Pancreatitis aguda recurrente secundaria a disfunción del esfínter de oddi: Reporte de caso

La disfunción del esfínter de Oddi (DEO) es una patología poco frecuente que debe ser considerada en el diagnóstico diferencial de pacientes con episodios de dolor biliar o pancreatitis aguda recurrente y antecedente de colecistectomía. Generalmente son pacientes con múltiples consultas, en los cuales la patología ha afectado considerablemente su calidad de vida. El diagnóstico se sustenta en la clínica, los marcadores serológicos y los medios diagnósticos de soporte, que se solicitan según el componente esfinteriano sospechado. El tratamiento con mayor eficacia es la esfinterotomía endoscópica. El uso de prótesis es aceptado, pero discutido. Se presenta el caso de un paciente masculino en la cuarta década de la vida que consultó por múltiples episodios de pancreatitis aguda recurrente con estudios de etiología que sospecharon disfunción del esfínter de Oddi pancreático y quien fue llevado a manejo endoscópico, con mejoría de su cuadro clínico.

Sphincter of Oddi Dysfunction (SOD) is a rare pathology that should be considered in the differential diagnosis of patients with biliary pain episodes or recurrent acute pancreatitis and a background of cholecystectomy. Generally, these are patients with multiple consultations where this pathology has considerably affected their quality of life. Diagnosis is based on clinical findings, serological markers and supporting diagnostic tests requested according to the suspected sphincteric component. The most effective treatment is endoscopic sphincterotomy. The use of prosthesis is accepted but debated. We present the case of a male patient in his forties who consulted for multiple episodes of recurrent acute pancreatitis with etiology studies suspecting dysfunction of the pancreatic sphincter of Oddi and who was taken to endoscopic management with improvement of his clinical picture.

Comparing one-step common bile duct exploration plus cholecystectomy with two-step endoscopic sphincterotomy plus cholecystectomy in patients over 80 years with concomitant gallbladder and common bile duct stones / 中华肝胆外科杂志

Objective:To compare safety and efficacy of one-stage laparoscopic common bile duct exploration plus laparoscopic cholecystectomy (LCBDE+ LC) with endoscopic retrodrade cholangiopancreatography plus laparoscopic cholecystectomy (ERCP+ LC) in elderly patients with concomitant gallbladder and common bile duct (CBD) stones.Methods:This is a two-center retrospective study with clinical data on 492 patients aged over 80 years diagnosed with concomitant gallbladder and CBD stones treated between January, 2014 and December, 2020 at The First Affiliated Hospital of Wenzhou Medical University and Quzhou Hospital Affiliated to Wenzhou Medical University. There were 254 males and 238 females, aged (83.9±3.0) years. These patients were divided into two groups based on their operative methods: the one-stage group (LCBDE+ LC, n=186) and the two-stage group (ERCP+ LC, n=306). Differences in surgery, stones and hospitalization costs were compared between the two groups. Results:When compared with the ERCP+ LC group, the LCBDE+ LC group had significantly higher incidences of previous gastrectomy [21.5%(40/186) vs 4.2%(13/306)], multiple stones [77.4%(144/186) vs 49.3%(151/306)], larger stone diameter [13.7(6.4, 18.6)mm vs 10.9(5.7, 16.1) mm], and increased hospitalization expenditure [(2.37±0.31) Wanyuan vs (3.26±0.44) Wanyuan] (all P<0.05). However, the rates of residual stone [2.7%(5/186) vs 1.3%(4/306)], stone recurrence [2.2%(4/186) vs 5.2%(16/306)], postoperatively overall complications [3.2%(6/186) vs 1.3%(4/306)], and total hospital stay [(10.7±6.2) d vs (11.3±5.4) d] were not significantly different between the two groups (all P>0.05). Conclusions:Allowing for the similar safety and effectiveness, and lower hospitalization expenditure, LCBDE+ LC was a preferred choice for patients aged over 80 year, especially in patients who had previous gastrectomy, multiple large CBD stones, or who could not accept endoscopic procedures for treatment of CBD stones.

Clinical disputes between sphincter of Oddi function and biliary system diseases / 中华消化外科杂志

The link between sphincter of Oddi function with biliary system (gallbladder and bile duct) diseases is considered to be very complicated. Whether routine prophylactic laparos-copic cholecystectomy should be carried out after endoscopic sphincterotomy to remove bile duct stones has been controversial worldwide. Actually, this is a very common and important clinical question which needs to be answered. The author spends a lot of time and efforts to broadly read and analyze on published articles related to this topic, and tries, from the aspects of the anatomy and function of sphincter of Oddi, the biliary diseases causing by dysfunction or discordance of sphincter of Oddi, and the impacting of artificial destruction of sphincter of Oddi on the gallbladder and bile duct of patients, to come up with an answer to this question based on scientific and medical evidence.

Experiencia del manejo por colangiopancreatografía retrógrada endoscópica de las fístulas biliares poscolecistectomía en un hospital de referencia en Colombia / Experience in endoscopic retrograde cholangiopancreatography management of postcholecystectomy biliary leak in a Colombian referral hospital

Resumen Introducción: la fistula biliar poscolecistectomía es poco frecuente. El manejo principalmente es endoscópico, pero en la literatura no hay consenso en la técnica de primera línea entre papilotomía, prótesis biliar o su combinación. Metodología: se realizó un estudio observacional tipo serie de casos en el que se incluyeron todas las CPRE realizadas en el Hospital Universitario San Ignacio en Bogotá, Colombia, entre enero de 2010 y marzo del 2021 por fistula biliar posterior a colecistectomía. Se registraron las características demográficas, manifestaciones clínicas, resolución, eventos adversos y estancia hospitalaria según la técnica endoscópica. Resultados: se incluyeron 24 pacientes con fistula biliar poscolecistectomía que se manejaron con CPRE. La mediana de edad fue de 59 años (rango intercuartílico [RIC]: 53,5-67). En el 75% el tipo de cirugía fue laparoscópica. La manifestación clínica más frecuente fue aumento del drenaje biliar > 150 mL/24 horas (50%), seguido de dolor abdominal (39%). La principal localización fue el conducto cístico en el 40%. El manejo con papilotomía fue del 25%; con prótesis biliar, 8,4%, y combinado, 66%; la resolución de la fístula ocurrió en el 100%, 50% y 87%, respectivamente, con menor estancia hospitalaria en el manejo combinado de 3,5 días frente a 4 días en papilotomía. Solo se presentó 1 evento adverso de hemorragia en el grupo de papilotomía. Conclusión: la papilotomía y la terapia combinada son opciones terapéuticas con buenas tasas de resolución y baja estancia hospitalaria para el manejo de las fistulas biliares poscolecistectomía. Se requerirán estudios prospectivos, aleatorizados y multicéntricos para definir la técnica con mejores desenlaces clínicos.

Abstract Introduction: Postcholecystectomy biliary leak is rare. Management is mainly endoscopic, but in the literature, there is no consensus on the first-line technique between sphincterotomy, biliary stent, or combination. Materials and methods: A case series study was conducted that included all ERCP performed at the San Ignacio University Hospital in Bogotá, Colombia, between January 2010 and March 2021 due to biliary leak after cholecystectomy. Demographic characteristics, clinical manifestations, resolution, adverse events, and hospital length stay were recorded according to the endoscopic technique. Results: 24 patients with postcholecystectomy biliary leak managed with ERCP were included. The median age was 59 years (interquartile range [IQR]: 53.5-67). In 75% the surgery was laparoscopic. The most frequent clinical manifestation was increased biliary drainage > 150 mL/24 hours (50%), followed by abdominal pain (39%). The main fistula's location was the cystic duct in 40%. Management with sphincterotomy was 25%, with a biliary stent, 8.4%, and combined, 66%; leak resolution occurred in 100%, 50%, and 87%, respectively, with a shorter hospital length stay in the combined management of 3.5 days compared to four days in sphincterotomy. Only one adverse bleeding event occurred in the sphincterotomy group. Conclusion: Sphincterotomy and combined therapy are options with reasonable resolution rates and low hospital length stay for managing postcholecystectomy biliary leak. Prospective, randomized, and multicenter trials will be required to define the best technique.

Clinical trial combining botulinum toxin A injection and fissurectomy for chronic anal fissure: a dose-dependent study

ABSTRACT Background Anal fissure is a common surgical disease that is usually treated conservatively. The golden surgical treatment for anal fissure is lateral internal sphincterotomy, but it may result in multiple complications. Therefore, other treatment methods have recently been introduced, and one of them is the injection of botulinum toxin A (BTA) and fissurectomy. In the present study, we aim to evaluate the effectiveness of the combination of fissurectomy and BTA injection in the treatment of chronic anal fissure by single surgeon. Materials and Methods The present is a non-randomized prospective cohort study conducted by a single surgeon in Saudi Arabia. Our sample was composed of 116 female patients, with mean age of 36.57 ± 11.52 years, who presented to our Surgical Outpatient Clinic with chronic anal fissure between October 2015 and July 2020, and were treated with BTA injection combined with fissurectomy. They were followed up for 1, 2, 3, 4, and 8 weeks, and after one year to evaluate the efficacy and safety of the treatment. The main outcomes analyzed were symptomatic relief, complications, recurrence, and the need for further surgical intervention. Results The treatment with BTA injection combined with fissurectomy was effective and safe in 115 patients (99.1%) at 1 year of follow-up. A total of 5 patients experienced recurrence at 8 weeks, which resolved completely with pharmacological sphincterotomy, and 12 patients experienced minor incontinence, which disappeared later. Conclusion In total, 70 units of BTA injection combined with fissurectomy is a suitable second-line treatment of choice for chronic anal fissure, with a high degree of success and a low rate of major morbidity.

Esfinterotomía lateral interna vs. toxina botulínica como tratamiento de la fisura anal / Lateral Internal Sphincterotomy versus Botulinum Toxin as Treatment of Anal Fissure

Introducción: La fisura anal crónica es una entidad frecuente que produce molestias durante y después de la defecación, su fisiopatología no es clara y su manejo es variado. La esfinterotomia lateral interna es una de las técnicas más utilizadas, aunque su elevado porcentaje de incontinencia no es aceptado y la inyección de toxina botulínica es una alternativa tentadora. Objetivo: Comparar los resultados de la inyección de toxina botulínica tipo A con la esfinterotomia lateral interna para tratamiento de la fisura anal en cuanto a dolor postoperatorio, recurrencia, curabilidad e incontinencia. Métodos: Se realizó un estudio tipo cohorte. A un grupo de 40 pacientes se trató con inyección de 50 UI de Toxina Botulínica tipo A y el otro grupo de 42 pacientes se le realizó esfinterotomia lateral interna. Los resultados se comparan estadísticamente para CI95 y error de 0,05. Resultados: La esfinterotomia vs toxina botulínica, resultó en cuanto a curabilidad en un 85,4 por ciento de los casos contra un 77,5 por ciento. Las recidivas se presentaron en 4,8 por ciento / 12,5 por ciento, la incontinencia ocurrió en 9,5 por ciento / 2,5 por ciento y el dolor posoperatorio estuvo presente en el 14,8 por ciento / 5,0 por ciento. Conclusiones: La esfinterotomia resultó mejor en cuanto a curabilidad y recidivas, mientras la aplicación de la toxina botulínica presentó mejores resultados en la incontinencia fecal y el dolor posoperatorio(AU)

Introduction: Chronic anal fissure is a frequent entity that produces discomfort during and after defecation. Its pathophysiology is not clear and its management is varied. Lateral internal sphincterotomy is one of the most used techniques, although its high percentage of incontinence is not accepted; botulinum toxin injection is therefore a tempting alternative. Objective: To compare the results of botulinum toxin type A injection or lateral internal sphincterotomy for treatment of anal fissure in terms of postoperative pain, recurrence, healing and incontinence. Methods: A cohort study was carried out. One group of 40 patients were treated with injection of 50 IU of botulinum toxin type A and another group of 42 patients underwent lateral internal sphincterotomy. The results were statistically compared with a confidence interval of 95 percent and error of 0.05. Results: Sphincterotomy and botulinum toxin were effective in terms of healing in 85.4 percent and 77.5 percent of cases, respectively. Recurrences occurred in 4.8 percent and 12.5 percent of cases, respectively. Incontinence occurred in 9.5 percent and 2.5 percent of cases, respectively. Postoperative pain was present in 14.8 percent and 5.0 percent of cases, respectively. Conclusions: Sphincterotomy was better in terms of healing and recurrence, while botulinum toxin application showed better results regarding fecal incontinence and postoperative pain(AU)

Open versus minimally invasive sphincter-sparing surgery for rectal cancer: a single-center retrospective cohort study in Peru / Cirugía abierta versus mínimamente invasiva con preservación del esfínter para el cáncer de recto: un estudio de cohorte retrospectivo de un solo centro en Perú

ABSTRACT Objective : The study aimed to describe and compare minimally invasive surgery (MIS) and open surgery for rectal cancer in Peru. Material and methods : A retrospective single-center analysis was performed for all patients who underwent sphinctersparing surgery for non-metastatic rectal cancer at Instituto Nacional de Enfermedades Neoplásicas in Peru between January 2016 and December 2020. Clinical, perioperative, pathological, and survival outcomes were compared between both groups. A propensity score matching method was used to minimize bias. Results : 162 patients were included in the final analysis. 124 had open surgery and 38 had MIS. Patients, clinical tumour, pathological characteristics, and perioperative were similar between groups after matching. Similar circumferential resection margin (CRM) with optimal quality of the mesorectum (p=1.000) but higher number of lymph nodes resected in open surgery group (p=0.741) was described. The leakage rate was slightly higher in the MIS group (p=0.358) with 10.5%, while the postoperative hospital stay was longer in the open surgery group after matching (p=0.001; OR 95% 5.2 CI: 1.8-15.6). The estimated recurrence-free survival (RFS) and overall survival (OS) at 3 years in open surgery and MIS was 71.8% (95% CI; 0.58-0.89) and 70% (95% CI; 0.56-0.88) (p=0.431) and 77.7% (95% CI; 0.64-0.94) and 88.9% (95% CI; 0.79-0.99) (p=0.5), respectively. Conclusions: Shorter postoperative hospital stay in the minimally invasive surgery group was reported. RFS, OS, and recurrence rates were similar between both groups. This approach is for non-metastatic rectal cancer in referral centers in Peru.

RESUMEN Objetivo : El estudio tuvo como objetivo describir y comparar la cirugía mínimamente invasiva (CMI) y la cirugía abierta para el cáncer de recto en el Perú. Material y métodos : Se realizó un análisis retrospectivo unicéntrico de todos los pacientes que se sometieron a cirugía conservadora de esfínter por cáncer de recto no metastásico en el Instituto Nacional de Enfermedades Neoplásicas de Perú entre enero de 2016 y diciembre de 2020. Clínica, perioperatoria, patológica y supervivencia se compararon los resultados entre ambos grupos. Se utilizó un método de emparejamiento por puntaje de propensión para minimizar el sesgo. Resultados : 162 pacientes fueron incluidos en el análisis final. 124 tuvieron cirugía abierta y 38 CMI. Los pacientes, el tumor clínico, las características patológicas y el perioperatorio fueron similares entre los grupos después del emparejamiento. Se describió un margen de resección circunferencial (MRC) similar con calidad óptima del mesorrecto (p=1,000) pero mayor número de ganglios linfáticos resecados en el grupo de cirugía abierta (p=0,741). La tasa de fuga fue ligeramente superior en el grupo CMI (p=0,358) con un 10,5%, mientras que la estancia hospitalaria postoperatoria fue mayor en el grupo de cirugía abierta tras el emparejamiento (p=0,001; OR 95% 5,2 IC: 1,8-15,6). La supervivencia libre de recidiva (SLR) estimada y la supervivencia global (SG) a los 3 años en cirugía abierta y CMI fue del 71,8% (IC 95%; 0,58-0,89) y del 70% (IC 95%; 0,56-0,88) (p=0,431) y 77,7% (IC 95%; 0,64-0,94) y 88,9% (IC 95%; 0,79-0,99) (p=0,5), respectivamente. Conclusiones : Se reportó menor estancia hospitalaria postoperatoria en el grupo de cirugía mínimamente invasiva. Las tasas de SLR, SG y recurrencia fueron similares entre ambos grupos. Este abordaje es para cáncer de recto no metastásico en centros de referencia en Perú.

Clinical application of two kinds of minimally invasive methods in choledocholithiasis complicated with gallbladder stones / 中华胰腺病杂志

Objective:To compare the clinical effectiveness of laparoscopic cholecystectomy (LC)+ laparoscopic choledocholithotomy (LCBDE)+ one-stage suture and primary choledocholithotomy with endoscopic retrograde cholangiopancreatography (ERCP)+ endoscopic duodenal sphincterotomy (EST)+ nasobiliary drainage (ENBD)+ LC in the treatment of choledocholithiasis complicated with gallbladder stones.Methods:A total of 200 patients with choledocholithiasis complicated with gallbladder stones admitted to the General Surgery Department of Shanxi Bethune Hospital from June 2015 to February 2021 were collected, and patients were divided into LC+ LCBDE+ one-stage suture (one-stage suture group, n=130) and ERCP+ EST+ ENBD+ LC (endoscopic surgery group, n=70) according to different treatments. The amount of intraoperative blood loss, operation time, postoperative feeding time, postoperative incidence of pancreatitis, cholangitis and other complications (biliary leakage, abdominal bleeding, wound infection), hospitalization costs, postoperative hospital stay, etc were compared between two groups. Results:The postoperative incidence of pancreatitis in the one-stage suture group (0.7% vs 5.7%) and the hospitalization cost [(2.74±0.39) ten thousand yuan vs (3.86±0.63) ten thousand yuan] were significantly lower than those in the endoscopic surgery group. The operation time [(103.21±9.36) min vs (88.18±7.20)min] was significantly longer than that of the endoscopic surgery group, and postoperative feeding time [(3.3±0.3)d vs (2.2±0.8)d] were significantly later than the endoscopic surgery group ( P<0.05). The amount of intraoperative blood loss [(36.0±3.0)ml vs (37.3±2.7)ml], the incidence of postoperative cholangitis (1.5% vs 2.9%) and other complications [biliary leakage (2.3% vs 1.4%), abdominal bleeding (1.5% vs 4.3%), wound infection(0 vs 0)], postoperative hospital stay [(6.8±1.3)d vs (7.1)d] had no significant differences between the two group. Conclusions:The two minimally invasive methods for the treatment of choledocholithiasis complicated with gallbladder stones had good efficacy, but LC+ LCBDE+ one-stage suture can retain the sphincter function of Oddis, maintain the normal anatomy and physiology of the biliary tract, reduce the incidence of related complications, and contribute to the recovery of patients, with high safety, effectiveness and feasibility.

The Effect of Adjuvant Pudendal Nerve Block in Post-Operative Pain Following Perianal Surgery for Non Suppurative Conditions.

Background: Surgical management of non-suppurative perianal conditions are associated with intense pain in the postoperative period. Day case surgeries are often not possible for such conditions due to the need for post operative analgesia. The addition of pudendal nerve block lessens the post operative pain and hence avoids the need for opioids and its side effects. Aim: To assess the effectiveness of Pudendal nerve block in post -operative pain following perianal surgery for non suppurative conditions. Methods and material: Prospective cohort study. Patients undergoing surgical modality for anal fissures and hemorrhoids are divided into two groups. Group A receives pudendal nerve block (local infiltration) along with Spinal anaesthesia. Group B receives only Spinal anaesthesia. Post-operative pain (visual analog score) was analyzed and results compared. Results: It was found that there was a statistically significant association between being given pudendal nerve block and the need for analgesics post operatively. Conclusion: Pudendal block with local infiltration, if properly administered has excellent results with regard to patient’s pain tolerance, postoperative outcome and probable cost effectiveness. We conclude that the addition of pudendal nerve block with spinal anesthesia for non-suppurative anal conditions reduces the post operative pain and avoids the need for opioids and its side effects. It is safe and effective and it lessens the duration of hospital stay there by providing the patient with less stress of staying in the hospital for longer periods.

Canulação biliar difícil: devemos tentar uma segunda CPRE após uma fistulotomia papilar mal-sucedida? / Difficult biliary cannulation: should we always try a second ercp after a failed needle-knife fistulotomy?

ABSTRACT BACKGROUND: A successful bile duct cannulation is a prerequisite for the realization of endoscopic retrograde cholangiopancreatography (ERCP). When biliary cannulation is not possible, needle-knife fistulotomy (NKF) can be performed. However, when biliary access is not successfully achieved even after performing NKF, it is possible to interrupt the procedure, and repeat the ERCP after a short interval. OBJECTIVE: The aim of this study is to analyze if repeating an ERCP after a short interval of 48 hours is effective in achieving biliary access after an initial NKF was unsuccessfully performed. METHODS: A total of 1024 patients with a naive papilla, that underwent ERCP between the years of 2009-2019, were retrospectively reviewed. Difficult biliary cannulation was identified in 238 of these cases and NKF was performed. Success of biliary cannulation, NKF success at the first and second ERCPs, the associations between the type of the papilla, biliary dilatation, and overall success of NKF and adverse events rates were evaluated. RESULTS: Biliary access was initially achieved in 183 (76.8%) cases. Of the 55 (23.1%) remaining cases a second attempt was performed after 48 hours, and biliary access was successfully achieved in 46 (83.6%) of them. The overall success of NKF after the first and second ERCP, the success rate was 96.2%. Papilla located out of its normal position was related to a minor chance of success at NKF (P<0.05). CONCLUSION: We conclude that when biliary access is not achieved after the performance of a NKF, a second attempt is safe and effective and should be attempted.

RESUMO CONTEXTO: A canulação biliar de sucesso é pré-requisito para a realização da colangiopancreatografia retrógrada endoscópica (CPRE). Quando a canulação biliar não é possível, a fistulotomia com auxílio do cateter Needle-Knife (NKF) pode ser realizada. Entretanto, quando o acesso biliar não é atingido mesmo após a realização de um NKF, é possível optar-se pela interrupção do procedimento, e pela repetição da CPRE após curto intervalo de 48 horas. OBJETIVO: O objetivo desse estudo é analisar se a repetição da CPRE após um curto intervalo de 48 horas é efetivo em atingir o acesso biliar, quando um NKF foi realizado inicialmente sem sucesso. MÉTODOS: Um total de 1024 pacientes com papila virgem de tratamento, submetidos à CPRE entre os anos de 2009-2019, foram retrospectivamente analisados. Canulação biliar difícil foi identificada em 238 deles, e NKF foi então realizado. Foram avaliadas as taxas de sucesso durante a canulação biliar, assim como durante a realização de NKF na primeira e segunda CPREs. A associação entre o tipo de papila, dilatação biliar e o sucesso final na realização do NFK também foi avaliada, assim como a presença de eventos adversos associados à realização do NKF. RESULTADOS: Dentre todos os NKF realizados, acesso biliar foi inicialmente atingido em 183 (76,8%) casos. Os 55 (23,1%) casos restantes, foram submetidos a uma segunda CPRE após 48 horas e o acesso biliar foi atingido em 46 (83,6%) deles, resultando em uma taxa final de sucesso, após a primeira e segunda CPREs, de 96,2%. Papila localizada fora da sua posição habitual foi relacionada a menor chance de sucesso durante a realização de NKF (P<0,05). CONCLUSÃO: Concluiu-se que quando o acesso biliar não pode ser atingido após a realização de um NKF, uma segunda CPRE é segura, efetiva e deve ser realizada.

Disfunción del esfínter de Oddi: un reporte de caso / Sphincter of Oddi dysfunction: Case report

Resumen La disfunción del esfínter de Oddi es un síndrome clínico causado por una enfermedad funcional (discinesia) o estructural (estenosis). La prevalencia estimada de disfunción del esfínter de Oddi en la población en general es del 1 %; aumentando a 20 % para pacientes con dolor persistente posterior a colecistectomía y a 70 % en pacientes con pancreatitis aguda recurrente idiopática. Se caracteriza clínicamente por la presencia de dolor abdominal, similar al cólico biliar o dolor tipo pancreático en ausencia de patología biliar orgánica; así como en pacientes con pancreatitis recurrente idiopática asociada con elevación de enzimas pancreáticas o hepáticas, y dilatación del conducto biliar o pancreático. El tratamiento para la disfunción del esfínter de Oddi tipo I se basa en la realización de esfinterotomía endoscópica, pero existe controversia en el manejo de la disfunción del esfínter de Oddi tipo II y III. En este artículo se presenta el caso clínico de una paciente de 67 años con antecedente de colecistectomía por laparotomía. Después del procedimiento quirúrgico refirió un dolor abdominal de predominio en el hipocondrio derecho tipo cólico asociado con emesis de características biliares. En el reporte de colangiorresonancia se encontró una ligera dilatación de la vía biliar intrahepática y gammagrafía con ácido iminodiacético hepatobiliar (HIDA) diagnóstica de disfunción del esfínter de Oddi. Se realizó una esfinterotomía endoscópica. En el seguimiento, dos años después, la paciente se encontraba asintomática con la disfunción del esfínter de Oddi resuelta.

Abstract Sphincter of Oddi dysfunction is a clinical syndrome caused by functional (dyskinesia) or structural (stenosis) disease. The estimated prevalence of this condition in the general population is 1%, reaching 20% in patients with persistent pain after cholecystectomy and 70% in patients with idiopathic recurrent acute pancreatitis. It is clinically characterized by the presence of abdominal pain, similar to biliary colic or pancreatic pain in the absence of organic biliary disease. It is also observed in patients with idiopathic recurrent pancreatitis, associated with elevated pancreatic or hepatic enzymes, and bile duct and/or pancreatic duct dilatation. Treatment for sphincter of Oddi dysfunction type I is based on endoscopic sphincterotomy, but there is controversy regarding the management of sphincter of Oddi dysfunction types II and III. This article presents the clinical case of a 67-year-old female patient with a history of cholecystectomy by laparotomy. After the surgical procedure, she reported abdominal pain predominantly in the right hypochondrium, colicky, associated with emesis of biliary characteristics. Cholangioresonance report revealed mild intrahepatic bile duct dilatation, and scintigraphy with HIDA scan showed sphincter of Oddi dysfunction. Endoscopic sphincterotomy was performed. The patient was asymptomatic and the sphincter of Oddi dysfunction had resolved at two-year follow-up.

Valoración de la colangiopancreatografía retrógrada endoscópica como medio diagnóstico/terapéutico en pacientes con íctero obstructivo / Assessment of the endoscopic retrograde cholangiopancreatography as a diagnostic/therapeutic mean in patients with obstructive jaundice

RESUMEN Introducción: las enfermedades del eje pancreático/biliar son una consecuencia en la morbimortalidad del aparato digestivo, y es la causa en ocasiones de una obstrucción biliar. La colangiopancreatografía retrógrada endoscópica es un método preciso para el diagnóstico de la obstrucción biliar, y se asocia con una elevada tasa de sensibilidad y especificidad. Materiales y métodos: se realizó un estudio observacional descriptivo de corte transversal, con el objetivo de valorar el comportamiento de la colangiopancreatografía retrógrada endoscópica como medio diagnóstico y terapéutico en una muestra de 90 pacientes con dictamen presuntivo de íctero obstructivo. Resultados: predominaron las féminas en el grupo de edad superior a los 50 años. La coluria, la acolia y el íctero como representativos de una enfermedad obstructiva de las vías biliares, fueron las manifestaciones más frecuentes, corroboradas por el estudio endoscópico, donde la litiasis coledociana fue la principal causa de íctero. Conclusión: la esfinterotomía endoscópica fue el proceder terapéutico de elección, y la pancreatitis aguda postintervención fue la complicación más frecuente (AU).

ABSTRACT Introduction: the diseases of the pancreatic-biliary axis are a consequence in the digestive tract morbidity-mortality, and sometimes they are the cause of a biliary obstruction. The endoscopic retrograde cholangiopancreatography is a precise method for diagnosing the biliary obstruction, and is associated to high rates of sensitivity and specificity. Materials and methods: a cross-sectional, descriptive, observational study was carried out with the aim of assessing the behavior of endoscopic retrograde cholangiopancreatography as a therapeutic and diagnostic mean in a sample of 90 patients with presumptive report of obstructive jaundice. Results: women aged more than 50 years predominated. Choluria, acholia and jaundice, as representative of the biliary ducts obstructive disease, were the most frequent manifestations, corroborated by the endoscopic study, where choledocal lithiasis was the main cause of jaundice. Conclusions: endoscopic sphincterotomy was the elective therapeutic procedure, and post-intervention acute pancreatitis was the most frequent complication (AU).

Esfincterotomia isolada versus esfincterotomia associada a passagem de prótese biliar no tratamento de fístulas biliares: 10 anos de experiência de um hospital quaternário / Sphincterotomy alone versus sphincterotomy and biliary stent placement in the treatment of bile leaks: 10 year experience at a quaternary hospital

ABSTRACT BACKGROUND: Hepatobiliary surgery and hepatic trauma are frequent causes of bile leaks and this feared complication can be safely managed by endoscopic retrograde cholangiopancreatography (ERCP). The approach consists of sphincterotomy alone, biliary stenting or a combination of the two but the optimal form remains unclear. OBJECTIVE: The aim of this study is to compare sphincterotomy alone versus sphincterotomy plus biliary stent placement in the treatment of post-surgical and traumatic bile leaks. METHODS: We retrospectively analyzed 31 patients with the final ERCP diagnosis of "bile leak". Data collected included patient demographics, etiology of the leak and the procedure details. The treatment techniques were divided into two groups: sphincterotomy alone vs. sphincterotomy plus biliary stenting. We evaluated the volume of the abdominal surgical drain before and after each procedure and the number of days needed until cessation of drainage post ERCP. RESULTS: A total of 31 patients (18 men and 3 women; mean age, 51 years) with bile leaks were evaluated. Laparoscopic cholecystectomy was the etiology of the leak in 14 (45%) cases, followed by conventional cholecystectomy in 9 (29%) patients, hepatic trauma in 5 (16%) patients, and hepatectomy secondary to neoplasia in 3 (9.7%) patients. The most frequent location of the leaks was the cystic duct stump with 12 (38.6%) cases, followed by hepatic common duct in 10 (32%) cases, common bile duct in 7 (22%) cases and the liver bed in 2 (6.5%) cases. 71% of the patients were treated with sphincterotomy plus biliary stenting, and 29% with sphincterotomy alone. There was significant difference between the volume drained before and after both procedures (P<0.05). However, when comparing sphincterotomy alone and sphincterotomy plus biliary stenting, regarding the volume drained and the days needed to cessation of drainage, there was no statistical difference in both cases (P>0.005). CONCLUSION: ERCP remains the first line treatment for bile leaks with no difference between sphincterotomy alone vs sphincterotomy plus stent placement.

RESUMO CONTEXTO: Cirurgia hepatobiliar e trauma hepático são causas frequentes de fístulas biliares, e esta temida complicação pode ser manejada de forma segura através da colangiopancreatografia retrógrada endoscópica (CPRE). O procedimento consiste em esfincterotomia isolada, passagem de prótese biliar ou combinação das duas técnicas, porém a forma ideal permanece incerta. OBJETIVO: O objetivo desse estudo é comparar a realização de esfincterotomia isolada versus locação de prótese biliar no tratamento de fístulas pós-cirúrgicas e traumáticas. MÉTODOS: Foram analisados de forma retrospectiva 31 CPREs com diagnóstico final de "fístula biliar". A informação colhida incluía dados demográficos dos pacientes, etiologia das fístulas e detalhes dos procedimentos. As técnicas de tratamentos foram divididas em dois grupos: esfincterotomia isolada vs esfincterotomia associada a locação de prótese biliar. Foram analisados os volumes dos drenos abdominais cirúrgicos antes e depois de cada procedimento e o número de dias necessários para que ocorresse cessação da drenagem pelo dreno abdominal cirúrgico após a CPRE. RESULTADOS: Um total de 31 pacientes (18 homens e 3 mulheres; idade média de 51 anos) com fístulas biliares foram avaliados. Colecistectomia laparoscópica foi a etiologia da fístula em 14 (45%) casos, seguida de colecistectomia convenvional em 9 (29%) pacientes, trauma hepático em 5 (16%) pacientes, e hepatectomia secundária a neoplasia em 3 (9,7%) pacientes. As localizações mais frequentes das fístulas foram: coto do ducto císticos com 12 (38,6%) casos, seguido de ducto hepático comum em 10 (32%) casos, ducto colédoco em 7 (22%) cases e leito hepático em 2 (6,5%) casos. 71% dos pacientes foram tratados com esfincterotomia associada a passagem de prótese biliar e 29% com esfincterotomia isolada. Houve diferença estatística em relação ao volume drenado antes e depois de ambos os procedimentos (P<0,05). Entretanto, quando comparada esfincterotomia isolada e esfincterotomia associada a passagem de prótese biliar, em relação ao volume drenado e ao número de dias necessários para cessação da drenagem, não houve diferença estatística em ambos os casos (P>0,005). CONCLUSÃO: A CPRE permanece como tratamento de primeira linha no tratamento de fístulas biliares, sem diferença entra a esfincterotomia isolada versus esfincterotomia associada a passagem de prótese biliar.

Fisura anal: anatomía, patogenia y tratamiento / Anal fissure - anatomy, pathogenesis and treatment

RESUMEN La fisura anal es una patología proctológica frecuente caracterizada por un desgarro oval en el anoder mo que, si bien es pequeño, puede producir mucho dolor y angustia en el paciente. La etiología exacta aún se discute, pero está relacionada con una hipertonía del esfínter anal en la mayoría de los casos. El tratamiento inicial es médico, con fármacos que disminuyen el tono del esfínter anal. Las fisuras cróni cas generalmente requieren tratamiento quirúrgico. La esfinterotomía interna lateral tiene un elevado porcentaje de éxito y se considera el tratamiento de referencia. En este artículo haremos una revisión de la anatomía, fisiopatología y opciones terapéuticas actuales de las fisuras anales.

ABSTRACT Anal fissure is a common anorectal condition. While it often presents as a small oval tear in the anoderm, it can cause significant pain and anguish to the patient. The exact etiology is still debatable but increased anal tone is associated with most fissures. The initial management is medical with agents intended to reduce the anal tone. More chronic fissures usually require surgical intervention. Lateral internal sphincterotomy has a high success rates and is considered the gold standard of interventions. In this article we review the relevant anatomy, pathophysiology and contemporary treatment options for anal fissures.

Indications, outcomes and complications of therapeutic endoscopic retrograde cholangiopancreatography procedures in a tertiary care centre in North East India

Background: Therapeutic endoscopic retrograde cholangiopancreatography (ERCP) is one of the most complex endoscopic procedures in the management of several pancreatobiliary diseases. There is no comprehensive data available till date about ERCP procedures from North East India. The aim of this study was to review the indications, outcomes and complications of endoscopic retrograde cholangiopancreatography (ERCP) procedures in a tertiary care centre of North East India.Methods: We retrospectively analysed the clinical records of all patients undergoing ERCP between July 2011 and November 2019. ERCP was performed under sedation (Midazolam + Pentazocine). Patient’s demographic characters, ERCP indications, outcome and post-ERCP complications were reviewed. Potential important patient and procedure related risk factors for overall post-ERCP complications were investigated.Results: A total 1038 patients were included in the study. Cannulation of the desired duct was successful in 89.2% of ERCPs. Among them male patients were 392 and females were 646. Mean age was 45 years and the age range were 7 to 92 years. Commonest indication was choledocholithiasis followed by malignancy. Overall Success rate was 82.66% with 84.64% in CBD stone and 75.65% in stenting of malignancy. Post ERCP complications developed in 96 patients (9.2%) and pancreatitis was the most common post-ERCP complication. Sedation related complications occurred only in few cases.Conclusions: Despite its associated morbidity and risk of mortality, ERCP is an important method for managing the pancreatic-biliary diseases. Indications, outcomes, and complications of therapeutic ERCPs in our centre are comparable to those reported from other centres.

A Prospective Interventional Study of Outcome of Internal Sphincterotomy in Closed Haemorrhoidectomy.

Haemorrhoids are nowadays a very common anorectal disease in the community. It may be attributed to increased consumption of more refined and junk food by the present generation of people. We have been seeing symptomatic haemorrhoids as early as late teenagers, and early 20's. Well, there are plenty of treatment options available, among them, in our hospital we have been doing Ferguson's closed haemorrhoidectomy, but pain and urinary retention are frequently seen and sometimes troublesome requiring removal of per-anal pack overnight/Foley’s catheterization. And also, in those patients with tight sphincters, because of straining to pass the stools for the first time, the wound margins used to give away, converting into an open haemorrhoidectomy. Aim of this study was to assess the effect of sphincterotomy in patients undergoing closed haemorrhoidectomy, in terms of immediate post-operative pain and urinary retention.METHODSPatients who came with symptomatic haemorrhoids to our hospital during the period January 2018 to August 2019 were assessed and patients requiring haemorrhoidectomy were included in the study according to inclusion and exclusion criteria. Patients included in the study were randomly divided into 2 groups (without/with sphincterotomy) till target of 50 was achieved. Post-operative outcomes of pain and incidence of urinary retention was compared among the 2 groups.RESULTSOn analysing the data regarding severity of pain and incidence of urinary retention between the 2 groups, there was significant difference (p value <0.001) in perceiving pain on all the days of assessment, and incidence of urinary retention was significantly low in sphincterotomy group (p value 0.001).CONCLUSIONSDoing internal sphincterotomy at the base of haemorrhoidectomy wound significantly reduces the immediate post-operative pain and urinary retention following closed haemorrhoidectomy. So, when sphincter tone is high, it's better and safer to do sphincterotomy to alleviate immediate post-operative pain and urinary retention.

Single centre randomized comparative trial of lateral internal sphincterotomy versus 2% diltiazem in chronic anal fissure

Background: Anal fissures are often encountered in surgical practice with surgery the gold standard management for chronic anal fissures. Recently the widespread use of pharmacologic agents for chronic fissures has increased. In our study we compare topical 2% diltiazem with lateral sphincterotomy with respect to symptoms such as relief of pain, ulcer healing, and side effects of treatments.Methods: A prospective comparative study, a total of 80 patients were randomized into 2 groups 40 each. Group A patients were subjected to open internal lateral sphincterotomy and group B to 2% topical diltiazem. The patients in both groups were followed up at 1st, 4th, 14th weeks and 6 months in OPD and were assessed for pain, sphincter tone and complications.Results: In group A (lateral anal sphincterotomy), patients achieved a good pain relief with a mean pain score of 1.98 by one week post procedure whereas group B (2% diltiazem) had taken 14 weeks to achieve similar pain relief (pain score of 1.5). At the end of 6 months, healing of fissure was noted in 100% of group A and in 90% of group B. 4 patients (10%) had recurrences in group B. Flatus incontinence was reported in 2 patients (5%) in group A although transient.Conclusions: Lateral anal sphincterotomy is superior to 2% diltiazem especially in healing of fissure, pain relief, quality of life and recurrence. Pharmacologic agents should be reserved for patients who are unfit or unwilling for surgery or can be used as a bridge therapy till sphincterotomy can be planned.

Management of chronic anal fissures: a narrative review

Anal fissures are often encountered in surgical practice in both sexes. It is a distressing disease impacting quality of life and causes profound morbidity among those affected. If left untreated, it may lead onto perianal abscess or even malignancy in long standing cases. Surgery is the gold standard management for chronic anal fissures. Recently the widespread use of pharmacologic agents for chronic fissures has increased. The management of chronic anal fissures has migrated to an era of multifaceted approach. This narrative review looks into various studies spanning over a period of 16 years. Various articles were shortlisted and analyzed for efficacy of various treatment methods, their impact in hospital stay, quality of life improvement, recurrence rate and complications among various treatment methods. We concluded from this review, that open lateral internal sphincterotomy is still the gold standard method of treatment for chronic anal fissure. Among pharmacological agents, 2% diltiazem has the best effectiveness with good compliance rate. Modern surgical techniques like VY plasty can be reserved for special situations. We do not recommend the practice of manual anal dilatation.

Comparative study of closed versus open lateral internal sphincterotomy in the management of chronic anal fissure

Background: Anal fissure is a painful tear in distal anal canal extending from just below the dentate line to anal verge. Patient presents with pain during or after defecation and passage of bright red blood per anus. Various studies investigating chronic anal fissures show a large variation in healing rates for different modalities. The present study was carried out to evaluate effectiveness of closed versus open lateral internal sphincterotomy in treatment of patients with chronic anal fissure.Methods: A prospective study was conducted in the Department of Surgery, Pt. B.D. Sharma PGIMS, Rohtak. Group A and group B included 20 patients each with chronic anal fissure and managed by closed and open lateral internal sphincterotomy respectively and effectiveness was evaluated with regards to fissure healing, pain reduction, recurrence and incontinence after surgical treatment.Results: The mean pain scores on visual analogue scale at end of 1 week in group A and group B was not found to be statistically significant, whereas it was found to be statistically significant at 3 week and at 6 weeks. Delayed healing was seen in 1 patient of group B, whereas no patient in group A had delayed healing or absence of healing postoperatively.Conclusions:There was a significant difference between closed and open methods of lateral internal sphincterotomy in terms of relief in post-operative pain but as a whole both techniques did not show any statistically significant difference in terms of fissure healing, postoperative complications or recurrence at 3 months.
