Image-Guided Surgery for Common Bile Duct Stones After Roux-en-Y Gastric Bypass.

Background: The relationship between obesity with common bile duct stone (CBDS) is close and increases after a Roux-en-Y gastric bypass (RYGB). Due to the anatomical modification, direct endoscopic access is not always possible. For this reason, image-guided surgery (IGS) by percutaneous transhepatic biliary drainage (PTBD) of the common bile duct (CBD) could be a first-line approach for the treatment of post-RYGB choledocholithiasis. The aim of this study was to analyze the feasibility and safety of CBDS treatment after RYGB with IGS. Materials and Methods: We present a descriptive retrospective observational multicentric study on the treatment of choledocholithiasis in patients operated on for RYGB using IGS through a minimally invasive approach by PTBD. The diagnosis of CBDS was made according to the symptoms of the patients, supported by blood tests, and medical images. Treatment was planned in two stages: in the first step, a PTBD was performed, and in the second step the choledocholithiasis was removed. Results: Of a total of 1403 post-RYGB patients, 21 presented choledocholithiasis. Of these, n = 18 were included. Symptoms were reported in n = 15 (8 cholestatic jaundice, 7 cholangitis), whereas n = 3 were asymptomatic. Percutaneous treatment was performed in all these patients, treated with a balloon and stone basket. A hyperamylasemia without pancreatitis was observed in 3 patients. No complications or deaths associated with the procedure were reported. The average hospital stay was 8.6 days. Conclusion: IGS is an interesting option for the treatment CBDS after RYGB. For these patients, PTBD is feasible and safe.

Transhepatic Percutaneous Sustained Dilation with Multiple Catheters for the Management of Hepaticojejunostomy Benign Stricture.

Background: Benign biliary strictures (BBS) befall in ∼7%-23% after hepaticojejunostomy and in 0.3%-0.6% after cholecystectomies. Their treatment options include surgical, endoscopic, and percutaneous management. The percutaneous approach is an excellent mini-invasive option including balloon dilation, biodegradable stents, and sustained dilation, a procedure born endoscopically. However, when the endoscopic approach fails or it is not available, it is possible to perform it percutaneously. Aim: To estimate the technical and clinical success of sustained percutaneous dilation with multiple catheters (SPDMC) in hepaticojejunostomy strictures and the percentage of complications and recurrence. Materials and Methods: We conducted a retrospective study, from a prospective database from January 2010 to March 2019, of 17 patients with postoperative BBS who failed to percutaneous pneumatic balloon dilation and underwent SPDMC with a mean follow-up of 2 years. Results: Seventeen patients between 28 and 71 years of age underwent SPMDC with technical success of 100%; the average number of catheters used was 5.59 (95% confidence interval [CI] 5.12-6.06) achieving a dilatation diameter of 16.15 mm (95% CI 14.71-17.60), and the therapeutic success rate was 71%, with recurrences of stricture and complications of 29% and 18%, respectively. The mean time with SPMDC was 7.06 months (95% CI 5.56-8.56). The median follow-up after dilation was 16 months, with an average of 27.75 months (95% CI 14.15-41.34). Conclusion: SPMDC is a feasible technique with a high technical success rate, therapeutic success rate, and low morbidity and mortality.

Cirugía de Rescate, Una Opción Eficaz Para Colecistectomía Laparoscópica Difícil / Cohort Study: Rescue surgery, an effective option for difficult laparoscopic cholecystectomy

INTRODUCCIÓN: El tratamiento estándar de la colecistitis aguda es la colecistectomía laparos-cópica (CL). La colecistectomía laparoscópica estándar (CLE) requiere la disección del triángu-lo de Calot y la exposición del conducto cístico; este procedimiento está asociado a lesión del conducto biliar y sangrado del lecho hepático. La colecistectomía subtotal laparoscópica (CSL) podría ser una alternativa en estas situaciones, puesto que se considera como un procedimiento asociado a escasas complicaciones. MATERIALES Y MÉTODOS: Se realizó un estudio de cohortes prospectivo. El universo incluyó a 180 pacientes en quienes se realizó una colecistectomía difícil; la misma que fue definida como: empiema, gangrena, perforación, inflamación severa con fibrosis, síndrome de Mirizzi, plastrón vesicular, cirrosis hepática y variantes anatómicas. Se clasificó en dos grupos; Grupo 1 (colecis-tectomía tradicional, 90 pacientes), y Grupo 2 (colecistectomía de rescate, 90 pacientes), en el grupo 2 se emplearon técnicas de rescate como: Pribram, subtotal reconstructiva, fenestrativa y disección retrograda. Se consideró como evento resultante la presencia de complicaciones (le-sión de vía biliar, sangrado, colecciones y coledocolitiasis residual, infección del sitio quirúrgico). Para el análisis estadístico se usó el programa SPSS 22.0 y Epidat 3.1. RESULTADOS: Se observó que la incidencia general de complicaciones en los pacientes con co-lecistectomía difícil fue de 9.44%, la incidencia de complicaciones en expuestos (colecistectomía tradicional) fue del 14.44%, versus una incidencia en no expuestos (colecistectomía de rescate) del 4.44%; RR 3.25 (IC 95%: 1.02 ­ 9.58), p= 0.04. Entre las técnicas de rescate se empleó: cole-cistectomía retrógrada 63.33% (n=57), colecistectomía tipo Pribram modificada 21.1% (n=19), subtotal reconstructiva 14.44% (n=13), y subtotal fenestrativa 0.9% (n=1). CONCLUSIÓN: La colecistectomía de rescate en colecistectomía difícil es eficaz para disminuir el riesgo de complicaciones como sangrado y lesión de vía biliar, no existió diferencia entre la frecuencia de coledocolitiasis residual entre los dos grupos.(AU)

BACKGROUND: The standard treatment for acute cholecystitis is laparoscopic cholecystectomy. Standard laparoscopic cholecystectomy requires the dissection of Calot's triangle and exposure of the cystic duct; this procedure is associated with bile duct injury and bleeding from the liver vascular bed. Laparoscopic subtotal cholecystectomy could be an alternative in these situations, since it is considered as a procedure associated with few complications. METHODS: A prospective cohort study was conducted. The universe included 180 patients in whom a difficult cholecystectomy was performed; the same was defined as: empyema, gangrene, perfo-ration, severe inflammation with fibrosis, Mirizzi syndrome, vesicular plastron, liver cirrhosis and anatomical variants. It was classified into two groups; Group 1 (traditional cholecystectomy, 90 patients), and Group 2 (rescue cholecystectomy, 90 patients), group 2 used rescue techniques such as: Pribram, subtotal reconstructive, fenestrative and retrograde dissection. The presence of com-plications (bile duct injury, bleeding, collections and residual choledocholithiasis, infection of the surgical site) was considered as an event. The softwares SPSS 22.0 and Epidat 3.1 were used for the statistical analysis. RESULTS: It was observed that the general incidence of complications in patients with difficult cholecystectomy was 9.44%, the incidence of complications in exposed patients (traditional cho-lecystectomy) was 14.44%, versus an incidence in unexposed patients (salvage cholecystectomy). 4.44%; RR 3.25 (95% CI: 1.02 - 9.58), p= 0.04. The following techniques were used: retrograde chole-cystectomy 63.33% (n=57), modified Pribram cholecystectomy 21.1% (n=19), reconstructive subto-tal 14.44% (n=13), and fenestrative subtotal 0.9 % (n=1). CONCLUSION: Rescue cholecystectomy in difficult cholecystectomy is effective to reduce the risk of complications such as bleeding and bile duct injury; there was no difference between the frequen-cies of residual choledocholithiasis between the two groups.(AU)
