Abstract:
Background. There is only limited evidence available to justify generalized clinical classification and treatment recommendations for iatrogenic bile duct lesions. Methods. Data of 93 patients with iatrogenic bile duct lesions was evaluated retrospectively to analyse the variety of encountered lesions with the Hanover classification and its impact on surgical treatment and outcomes. Results. Bile duct lesions combined with vascular lesions were observed in 20 patients (21.5%). 18 of these patients were treated with additional partial hepatectomy while the majority were treated by hepaticojejunostomy alone (). Concomitant injury to the right hepatic artery resulted in additional right anatomical hemihepatectomy in 10 of 18 cases. 8 of 12 cases with type A lesions were treated with drainage alone or direct suture of the bile leak while 2 patients with a C2 lesion required a Whipple’s procedure. Observed congruence between originally proposed lesion-type-specific treatment and actually performed treatment was 66–100% dependent on the category of lesion type. Hospital mortality was 3.2% (). Conclusions. The Hannover classification may be helpful to standardize the systematic description of iatrogenic bile duct lesions in order to establish evidence-based and lesion-type-specific treatment recommendations.

Abstract:
Endodontic-periodontal diseases often present great challenges to the clinician in their diagnosis, management, and prognosis. Understanding the disease process through cause-and-effect relationships between the pulp and supporting periodontal tissues with the aid of rational classifications leads to successful treatment outcomes. In this report, we present several treatment modalities in patients with different endodontic-periodontal lesions. A modification to the new endodontic-periodontic classification, Al-Fouzan’s classification, was also added. The first case was classified as retrograde periodontal disease (i.e., primary endodontic lesion with drainage through the periodontal ligament). The second case was diagnosed as an iatrogenic periodontal lesion caused by root perforation. The third case was diagnosed as an iatrogenic periodontal lesion caused by tooth trauma due to orthodontic treatment. The first two cases were managed with a nonsurgical approach, whereas the third case was managed with nonsurgical and surgical approaches. All patients showed complete healing of soft and hard tissue lesions. A thorough understanding of the disease history and the patient’s signs and symptoms, complete examination with full investigation, and the use of a systematic step-by-step approach in the management of such challenging endodontic-periodontal lesions with regular recall visits were very useful and successful.

Abstract:
the lesions of the urinary organs of a iatrogenic origin correlated to hysterectomy surgery almost exclusively concern the ureter and the bladder. Lesions of the urinary organs caused during abdominal and vaginal hysterectomy for benign pathology were studied at the 1st Clinic of Obstetrics and Gynaecology of the University of Catania between 1st January 1989 and 31st December 2000. During this period 3,138 hysterectomies were performed, of which 2,765 (88.11%) abdominally and 373 (11.89%) vaginally. Altogether there were 11 (0.35%) iatrogenic lesions of the urinary excretory organs and these included 5 (0.15%) ureteral lesions and 6 (0.19%) bladder lesions. There were no lesions of the urethra. In 2,765 abdominal hysterectomies 4 (0.14%) ureteral lesions and 4 (0.14%) bladder lesions occurred, and in 373 vaginal hysterectomies one (0.27%) ureteral lesion and 2 (0.54%) bladder lesions occurred. In all cases, after adequate treatment the urinary organs healed completely.

Abstract:
Pseudoaneurysms are rare lesions with a multitude of causes, including infectious, traumatic, and iatrogenic origins. In addition, there are a number of potential treatment options, all of which require consideration to determine the most appropriate management. Historically, surgical intervention has been the method of choice, but because the histopathological features of these lesions make them largely unsuitable for clipping, trapping or excision is often required. More recently endovascular methods have been used, including coil embolization, stent reconstruction, or parent artery occlusion. Although these methods are often successful, situations arise in which they are not technically feasible. The authors describe such a case in a pediatric patient with an iatrogenic pseudoaneurysm. Onyx was used to embolize the lesion and the results were excellent.

Abstract:
Trigeminal nerve branches injuries are more and more frequent because of the wide spread of oral surgery. When the nerve damage involves the lingual nerve (LN) or the inferior alveolar nerve (IAN), the negative impact of the nervous dysfunction on the daily life of patients is relevant. Patients usually describe their condition as a crippling disease interfering with their common daily activities (talking, eating and drinking) and, consequently, forcing them to give up their social life. This difficult situation is undoubtedly worse when pain is present. It is about a neuropathic pain due to the nerve damage and the wrong regeneration process that make a mixture of nervous fibres and scar tissue. It is a dull pain described by one of our patient as “a monster that never gives up, always present as a new life-mate”. Moreover, all these feelings and patients’ adaptability have always to be correlate to the kind of surgery that caused the symptoms themselves. It’s not easy to understand and accept a complete lingual anaesthesia associated with continuous pain appeared after the removal of an asymptomatic wisdom molar! The same symptoms appeared after the removal of a malign tumour are usually more acceptable. Unfortunately, even today, there is no worldwide consensus about how to early recognize and eventually treat this kind of lesions. Nowadays, these iatrogenic nerve damages culminate more and more frequent in legal matters. A standardization of diagnostic and therapeutic management is necessary, to clarify which the correct approach for each patient is. This project aimed to standardize through the founding of a specific Clinic the management of patients affected by lingual nerve and inferior alveolar nerve lesion, in order to propose a common diagnostic process, followed by both the patient-specific reconstructive surgery and the regular clinic and neurophysiological follow up. The standardized management allows to understand the actual efficacy of this kind of surgery.

Abstract:
A lesão do nervo alveolar inferior é a complicação cirúrgica mais prevalente em Cirurgia Oral e Maxilo-facial. A causa mais comum da lesão é a extração de terceiros molares inferiores devido à sua relação de proximidade com o nervo. A colocação de implantes, a cirurgia ortognática e a técnica anestésica podem levar também à lesão do nervo tanto por laceração, compressão, corte, neurotoxicidade ou esmagamento. A prevenção da lesão é fundamental em qualquer procedimento devendo nesse sentido o diagnóstico ser realizado corretamente, recolhendo o máximo de informação possível. O médico-dentista tem ao seu dispor no mercado auxiliares de diagnóstico convencionais como a ortopantomografia ou a tomografia computorizada mas tem também auxiliares menos comuns em medicina-dentária como a ressonância magnética ou os ultrassons. Em casos de risco elevado ou que possam potencialmente resultar em lesão, o médico-dentista pode alterar o plano cirúrgico. A regeneração do nervo após a lesão vai depender principalmente da sua extensão. O médico-dentista deve sempre que possível esperar a regeneração espontânea do nervo. Quando essa regeneração não ocorra ou simplesmente não seja possível devido à gravidade da lesão, o médico-dentista deve sugerir o tratamento microcirúrgico da lesão podendo realizar, de acordo com a presença de neuroma, da extensão da lesão e da presença de continuidade do nervo, a neurorrafia direta, a colocação de enxertos ou a tubelização. As palavras-chave utilizadas foram: “Inferior alveolar nerve lesion ”, “third molars inferior alveolar nerve lesion ”, “implants inferior alveolar nerve lesion”, “inferior alveolar nerve iatrogenic damage”, “treatment inferior alveolar nerve lesion ”.
The lesion of the inferior alveolar nerve is the most prevalente surgical complication in Oral and Maxillo-Facial Surgery. The most common cause is the extraction of inferior third molars due to its proximity with the nerve. The implant placement, orthognathic surgery and the anesthetic technique can also lead to damage of the nerve by laceration, compression, cutting, neurotoxicity and crushing. Preventing the lesion is importante in any procediment though requiring the right diagnosis. The dentist has at his disposal various diagnostic techniques in the market such as orthopantomography and computed tomography or less common techniques as magnetic resonance imaging or ultrasound. In high risk cases or cases which have a higher probability of leading to a lesion, the dentist may change his surgical planning. The dentist should, if possible, wait for the spontaneous regeneration of the nerve. When the regeneration is not possible or it doesn’t occur due to the severity of the lesion, the dentist should suggest the microsurgical treatment of the lesion. Depending on the presense of neuroma, the extension of the damage and the continuity of the nerve, the dentist may use direct neurorrahaphy, placement of grafts and tubelization. The keywords used were: “Inferior alveolar nerve lesion ”, “third molars inferior alveolar nerve lesion ”, “implants inferior alveolar nerve lesion”, “inferior alveolar nerve iatrogenic damage”, “treatment inferior alveolar nerve lesion ”.

Abstract:
La colecistectomia laparoscopica (VLC) è una delle procedure chirurgiche più frequentemente eseguite nei paesi industrializzati ed è diventata negli anni il gold standard nel trattamento della patologia litiasica e delle sue complicanze. Tuttavia, l’utilizzo della laparoscopia comporta un aumento dell’incidenza di lesioni della via biliare principale (VBP) di circa 2-3 volte superiore rispetto alla tecnica open. L’incidenza della lesione iatrogena della VBP (LIVB) in letteratura si attesta tra lo 0,2-0,7% con l'approccio laparoscopico, comportando una significativa morbilità e mortalità, aumentando la degenza post operatoria e di circa il 126% il costo sanitario rispetto ad un intervento senza complicanze. Tra le cause principali di LIVB c’è una errata identificazione intraoperatoria delle strutture anatomiche quali il dotto cistico (DC), l’arteria cistica (AC) e la VBP prima della loro sezione. Il mancato riconoscimento di tali strutture è dovuto, nella maggior parte dei casi, ad anomalie anatomiche o a processi infiammatori come pregressa colecistite, pancreatite o calcolosi della VBP trattata endoscopicamente con CPRE che causano aderenze e determinano un ispessimento dei tessuti che rende difficoltoso il discernimento delle varie componenti. Le procedure diagnostiche e operative volte al riconoscimento intraoperatorio delle strutture anatomiche sono attualmente due: Colangiografia (IOC) e somministrazione endovenosa di verde indocianina (ICG) con visione in near infra red (NIR). L'uso routinario della IOC è controverso in quanto c’è un aumento significativo dei tempi operatori, implica costi aggiuntivi, necessità di incannulamento del dotto cistico o biliare con un concomitante aumento del rischio di lesione della VBP; inoltre, aumenta l’esposizione a radiazioni e necessità di ulteriori attrezzature e personale addestrato e spesso non è disponibile nelle strutture ospedaliere periferiche. L’utilizzo dell’ICG combinato con una camera con visione NIR è, per contro, eseguibile prima della dissezione del triangolo di Calot, non necessita di personale specializzato e non espone a radiazioni. Allo stato attuale la maggior parte degli studi in letteratura riporta risultati dell’utilizzo dell’ICG nelle colecistectomie non complicate da processi infiammatori, mancando di evidenze nei casi in cui, a seguito di alterazioni post infiammatorie, sarebbe più utile una corretta valutazione anatomica. Scopo di questo studio è valutare l’efficacia nell’identificazione delle strutture anatomiche in pazienti sottoposti a VLC per calcolosi della colecisti complicata da processi infiammatori, con e senza uso del Verde Indocianina

Abstract:
Le lesioni del nervo laringeo inferiore (N.L.I.) sono tra le possibili complicanze della chirurgia del collo e del mediastino. Tutta la chirurgia del mediastino e della regione anteriore del collo, compresa la chirurgia della carotide e dei vasi epiaortici, nonché gli accessi anteriori alla colonna cervicale, sono gravati dal rischio di una lesione di tale nervo. Sono state, inoltre, descritte in letteratura lesioni ricorrenziali iatrogeniche nella chirurgia di distretti lontani dal decorso del nervo, a seguito di errori tecnici legati all’uso della maschera laringea, in corso di anestesia generale. È comunque nella chirurgia della tiroide che la lesione iatrogenica del N.L.I. acquista un’incidenza significativa, in considerazione degli stretti rapporti anatomici tra esso e la ghiandola tiroide. La paralisi ricorrenziale è una grave complicanza della chirurgia tiroidea, non solo dal punto di vista del deficit della fonazione, ma anche, e soprattutto, dei disturbi della ventilazione. È stato infatti documentato come la riduzione del flusso aereo, conseguente a lesione ricorrenziale unilaterale, sia assimilabile a quella determinata da una stenosi tracheale del 30%. L’incidenza di questa complicanza si è ridotta dal 30% di Billroth e Wolfer (1844) allo 0.3-3% delle più recenti casistiche, grazie alle acquisizioni in campo anatomico ed al miglioramento della tecnica chirurgica. Dovremmo, quindi, considerare attualmente inammissibili percentuali di lesioni ricorrenziali superiori all’1%. Oggi le lesioni del N.L.I. possono essere riparate con tecniche di ricostruzione microchirurgiche. La ricostruzione del nervo può essere effettuata tramite neurorrafia termino-terminale, fascicolare, od utilizzando un innesto sia intervenendo immediatamente, sia intervenendo in un tempo successivo. Alternativamente si può eseguire un’anastomosi tra il N.L.I. e l’ansa dell’ipoglosso, in particolare la branca terminale diretta al muscolo sterno-tiroideo. Scopo della tesi è una revisione critica dei casi di ricostruzione del N.L.I. con tecnica microchirurgica e dei principi di tecnica chirurgica nella identificazione e preparazione del N.L.I. nella chirurgia del collo. Vengono discussi i risultati delle ricostruzione del N.L.I., dopo lesione iatrogenica, in pazienti provenienti da centri chirurgici diversi, eseguite dal 1991 all’Aprile 2003, nell’Unità di Microchirurgia (Coordinatore: Prof. Andrea Ortensi) del Dipartimento di Scienze Chirurgiche dell’Università di Roma “La Sapienza”, trattati sia con neurorrafia termino-terminale che con reinnervazione mediante ansa dell’ipoglosso.
The inferior laryngeal nerve (ILN) injury are among the possible complications of surgery of the neck and mediastinum. All surgery of the mediastinum and the anterior neck, including carotid surgery and neck vessels, as well as access to the anterior cervical spine, are burdened by the risk of damage to that nerve. Have been also described in the literature recurrent lesions in surgery of iatrogenic districts away from the course of the nerve, as a result of technical errors related to the use of the laryngeal mask, in the course of general anesthesia. It is still in surgery of the thyroid and iatrogenic lesions of the recurrent laryngeal nerve acquires a significant impact, given the close anatomical relationships between it and the thyroid gland. The paralysis recurrent is a serious complication of thyroid surgery, not only from the point of view of the deficit of the phonation, but also, and above all, of disorders of ventilation. It has been documented as the airflow, resulting in recurrent lesion unilateral, is comparable to that determined by a tracheal stenosis of 30%. The incidence of this complication was reduced by 30% of Billroth and Wolfer (1844) to 0,3-3% of the most recent series, thanks to the acquisitions of anatomy and improved surgical technique. We should, therefore, currently considered unacceptable rates of recurrent lesions greater than 1%. Today lesions of the ILN can be repaired with microsurgical reconstruction techniques. The reconstruction of the nerve neurorrhaphy can be performed by end to end, sort, or by using a grafting is intervening immediately, either by acting at a later time. Alternatively one can perform an anastomosis between the ILN and the loop of the hypoglossal, in particular the branch terminal direct to the sternothyroid muscle. The aim of the thesis is a critical review of the cases of reconstruction of the ILN with microsurgical techniques and principles of surgical technique in the identification and preparation of the ILN in surgery of the neck. It discusses the results of reconstruction of the ILN after iatrogenic injury in patients from different surgical centers, carried out from 1991 to April 2003, the Unit of Microsurgery (Coordinator: Prof. Andrea Ortensi) Department of Surgical Sciences University of Rome "La Sapienza", is treated with termino-terminal neurorrhaphy or with reinnervation by the hypoglossal loop.

Iatrogenic nerve lesions are frequently neglected. The chapter stresses the importance of adequate assessment, surgical timing, surgical strategies, follow-up, and results. Using the example of a radial nerve lesion in discontinuity due to osteosynthesis after humeral fracture, the authors describe a typical patient history with delayed presentation, as well as the role of physical examination, electrophysiology, and high-resolution ultrasound in demonstrating substantial nerve damage incompatible with spontaneous recovery. Surgical findings are demonstrated, along with a stepwise approach for nerve reconstruction via sural nerve graft. Clinical approach and surgery for traumatic radial nerve lesions are detailed, as well as general information on iatrogenic nerve lesions.

Abstract:
Spinal accessory nerve (SAN) injuries can be idiopathic or iatrogenic. Providers who understand the essential anatomy of the SAN can direct the history, physical exam, and ancillary studies to localize the lesion, while considering the differential diagnosis. The differential diagnosis includes both traumatic and atraumatic causes, including penetrating or blunt trauma to the neck, fracture malunion, glenohumeral instability, brachial neuritis, progressive neuromuscular disease, and cerebrovascular accident. The chapter discusses the timing of, and indications for, operative exploration, with or without nerve repair, as well as the details of the surgical procedure. The authors provide instructive pearls for initial management, establishing patient expectations, and potential complications.

Abstract:
Transthoracic and transoesophageal echocardiography is the first-line diagnostic tool for imaging space-occupying lesions of the heart. Cardiac masses can be classified as tumours, thrombi, vegetations, iatrogenic material, or normal variants. Occasionally, extracardiac masses may compress the heart and create a mass effect. Cardiac masses may be suspected from the clinical presentation. This is the case in patients with an embolic event presumed of cardiac origin or in patients with infective endocarditis. Otherwise, a cardiac mass can be identified during the routine investigation of common, non-specific cardiac manifestations or as an incidental finding.In general, an integrated approach which correlates the patient’s clinical picture with the echocardiographic findings may reasonably predict the specific nature of encountered cardiac masses and, in the case of tumours, discriminate between primary versus secondary, and benign versus malignant. Furthermore, echocardiography alone or with complementary imaging modalities, can provide information to help decide on the resectability of cardiac tumours, enhance effective diagnosis and management of infective endocarditis, and assist in planning therapy and follow-up. Because several normal structures and variants may mimic pathological lesions, a thorough knowledge of potential sources of misinterpretation is crucial for a correct diagnosis. After surgical resection, histological investigation is mandatory to confirm the diagnosis.

Abstract:
Errors and violations are major contributors to iatrogenic harm in patients. Anesthesia is a complex process within the complex system that is healthcare. In complex systems, decisions need to be reviewed frequently and iteratively with reset baseline data. Errors are unintentional and cannot be avoided simply by trying harder or deterred by the threat of punishment; violations, on the other hand, are deliberate deviations from safe practice. Types of error are statistically predictable, and can be understood in relation to the cognitive processes involved in their generation: either System I thinking, or System II thinking. Safety depends on doing the right things correctly the first time, using a systems-based approach (drawing lessons from aviation and other high-reliability industries) within a just culture.

Abstract:
Introduction: Carpal tunnel syndrome is neuropathy of compressive origin, surgical treatment can present complications that are difficult to solve, among them, painful neuromas of the peripheral nerves, affecting 2–60% of patients with nerve damage. There is no consensus on the ideal treatment for painful neuroma. Consequently, numerous modalities to treat neuroma pain are described. Case report: Female, 45 years old, presented with a left hand carpal tunnel syndrome clinic. There is a report of having undergone a surgical procedure for decompression of the carpal tunnel with endoscopy, progressing with worsening of symptoms. Another surgical procedure was performed (conventional open route) in the region of the left wrist with intra-op visualization of total nerve rupture. Neurorrhaphy of the median nerve was performed. Patient came to our service complaining of severe pain (VAS 9/10) in median nerve topography associated with paresis of the muscles innervated by the same. Neuroma resection and sural nerve grafting for the tenar motor branch, ulnar and radial median group and patient evolved with significant pain improvement (VAS of 2/10). Discussion: A wide variety of surgical techniques are described to treat painful neuroma. In this case, the success of the chosen tchnique is evidenced by the drop of 07 points in the VAS. Conclusion: It is evident that the endoscopic correction of carpal tunnel syndrome is not without complications and should be indicated with caution. It is necessary to carry out more studies that can evidence the best conduct for each case.

Abstract:
Context: Central venous catheterization of the internal jugular vein is a common procedure that can be complicated with Horner`s Syndrome, caused by a direct lesion of cervical sympathetic pathways, pneumothorax compression, or carotid dissection. This entity should be considered when assessing new anisocoria in intensive care scenarios. Case Report: We report the case of a 64-year-old woman, who presented anisocoria during an intensive care unit hospitalization. She had been admitted with severe COVID-19 and need for mechanical ventilation. Her anisocoria was more evident in the dark, with right miosis, ipsilateral semi-ptosis, and preserved photoreaction reflexes. Before the anisocoria, she had a venous catheter inserted in her right jugular vein. Further evaluation showed a right pneumothorax, which was promptly drained after the mispuncture. The cervical arterial angiotomography showed no signs of carotid dissection. Conclusion: New anisocoria in critical patients is usually associated with impairment of the parasympathetic tonus, either by the use of topic or inhalatory anticholinergic drugs or cerebral herniation syndrome. However, in these situations, the anisocoria is more appreciable in light, with disruption of photoreaction in the greater pupil and ipsilateral ptosis. Therefore, we believe our patient developed an iatrogenic Horner`s Syndrome, secondary to a catheterization mispuncture, leading to a direct lesion of sympathetic pathways and their compression by the pneumothorax. Beyond parasympathetic pharmacologic blockade or cerebral herniation, Horner`s Syndrome constitutes a valuable differential diagnosis when evaluating patients with new anisocoria in the ICU.

Abstract:
Bile duct injury is a complication of cholecystectomy and may lead the patient to develop secondary biliary cirrhosis (SBC), an irreversible damage to the liver parenchyma caused by the chronic interruption of bile flow. Clinically, cirrhosis manifests when 80% of the liver parenchyma is affected with symptoms like pruritus, jaundice, coagulopathy, and ascites in advanced stages. Liver transplantation is an option of the treatment for SBC, especially when its progression leads to liver failure but there are conditions that strongly contraindicate the procedure, such as an active extrahepatic malignancy. We report a situation in which a patient with breast cancer underwent a liver transplant with good results over 10 years of follow-up. We report a 63-year-old woman, retired, healthy until 2001, when she was submitted for a cholecystectomy. After 15 days, the patient underwent a bile duct reconstruction due to an iatrogenic lesion of the bile duct. After 5 years of asymptomatic, she began to present anorexia, weight loss, jaundice, choluria, and fecal acholia, being diagnosed with SBC. The treatment with endoscopic retrograde cholangiopancreatography and the placement of stents in the bile ducts was initiated with no success. Therefore, she was referred to the liver transplant clinic of the Hospital Universitário Walter Cantídio, placed in Fortaleza-Ceará. On admission, the patient presented a regular general condition, oriented, icteric (++/4), and slimmer. The physical examination showed a symmetric thorax with a palpable lump in the right breast. Cardiac and pulmonary auscultations were normal. The patient had plane, flaccid, painless abdomen, with the presence of incisional hernia with spleen and palpable bowel loops. The laboratory tests showed the following results: creatinine 0.4 mg/dL; international normalized ratio (INR) 1.68; total bilirubin 17.9 mg/dL, being classified as CHILD B MELD 23. The patient also underwent an upper digestive endoscopy that exhibited esophageal varices. The abdominal ultrasound (US) presented signs of chronic liver disease, splenomegaly, and dilated intrahepatic bile ducts. In this case, it was also requested a breast US that revealed a lump on the right breast, measuring 1.5×1.1 cm. Then, she was referred to a mastologist, who requested a mammogram that showed an irregular, spiky, and high-density lump in the upper side quadrant of the right breast, measuring 12 mm. It was requested for a positron emission tomography, whose results excluded the possibility of metastasis. Then, the patient was submitted to a breast quadrantectomy with axillary dissection and removal of five lymph nodes, with freeze biopsy, confirming breast cancer with free margins and sentinel lymph node research. Histopathology of the breast piece revealed grade 2 infiltrating ductal carcinoma of the right breast, measuring 1.8×1.5 cm with angiolymphatic invasion and metastasis to 1 axillary lymph node of 3 mm. Immunohistochemistry examination was positive for estrogen and progesterone receptors, with low Ki-67 and negative HER-2, subtypes of LUMINAL A breast carcinoma. She underwent hormonal treatment, and adjuvant chemotherapy was not indicated. Due to the high risk of mortality associated with SBC, the patient was released by oncology and, in a multidisciplinary meeting with the participation of surgeons, hepatologists, and radiologists, it was decided to include the patient on the liver transplant list, performed 2 months after breast cancer surgery. After 10 years, the patient was monitored by the liver transplant service without recurrence of breast disease and with good liver graft function, using immunosuppressive therapy with everolimus 3.5 mg/day.

Abstract:
Chronic Pain (CP) affects one in five people in developing countries, and is the most frequent reason motivating medical visits. Some CP types rank as the most common symptomatic diseases affecting humans worldwide (eg, tension-type headache), and the most common cause of years lived with disability (eg, low back pain). Despite the high costs related to the diagnosis and management of CP, up to 40% of patients remain symptomatic despite best medical therapy. The relative inefficiency of CP management stems from several causes, lack of good predictors of response to treatment being one of them. Inefficient prognostication leads to low response to treatment, high odds of side-effect and iatrogeny, especially in CP syndromes where lesion to somatic or neural tissues are not the driving mechanisms leading to pain (primary headaches, low-back pain, fibromyalgia). We have developed an electronic medical record system specific for pain management and used it in 611 prospective patients addressed to our Institution. We then used structured and unstructured data from the first visit and used as an end-point of good outcome the two higher strata of the patients’ Global Impression of Change score (very much and much improved) systematically collected at the last visit, which took place within 12 months from the first. By using state of art AI algorithms in an interpretable approach, we obtained a list of 12 highly predictable variables, which included pain in specific pain areas of the body, sex, pain pattern and temporal profile. Using these variables, and their complex relationship, we developed a machine learning model that predicted a good long-term outcome at the moment of the first visit, yielding a sensitivity and specificity of 0.69 and 0.73, respectively, with an area under the curve of 0.71. When imputed with variables from the second visit, AUC numbers reached 0.85. Business Model: given the challenges that health systems around the world are facing, the main target today is to make the shift from a payper-use mode to a value-based approach. This will bring the patient to the center of medical decisions. Chronic pain is an ideal scenario to test new strategies directed to these goals. In fact, our strategy allowed the identification of patients who would not respond to traditional therapeutic approaches before they were implemented, potentially saving time, resources and mitigating suffering. Public health systems and integrated health operators can be greatly benefited using this tool by increasing treatment effectiveness and reducing losses. Lower costs for all enables more people to access good health faster. Market share: large health conglomerates with closed loops of care including diagnostic and health-care provider facilities using electronic data record systems.
