ABSTRACT
OBJECTIVE: Sphincter of Oddi dysfunction (SOD) has been used to describe patients with RUQ abdominal pain without an etiology. We conducted a systematic review and meta-analysis to evaluate the efficacy and safety of ES (endoscopic sphincterotomy) for SOD. METHODS: The study methodology follows the PRISMA guidelines. A comprehensive search was conducted using MEDLINE and EMBASE databases for RCTs with ES in patients with SOD. The primary outcome assessed was the improvement of abdominal pain after ES/sham. A random effects model was used to calculate pooled estimates for each outcome of interest. RESULTS: Of the initial 55 studies, 23 were screened and thoroughly reviewed. The final analysis included 3 studies. 340 patients (89.7% women) with SOD were included. All patients had a cholecystectomy. Most included patients had SOD type II and III. The pooled rate of technical success of ERCP was 100%. The average clinical success rate was 50%. The pooled cumulative rate of overall AEs related to all ERCP procedures was 14.6%. In the sensitivity analysis, only one study significantly affected the outcome or the heterogeneity. CONCLUSION: ES appears no better than placebo in patients with SOD type III. Sphincterotomy could be considered in patients with SOD type II and elevated SO basal pressure.

Introducción: la colocación endoscópica de stents para descomprimir una obstrucción biliar es un tratamiento comúnmente utilizado para enfermedades malignas de la vía biliar y para estenosis benignas de la misma. Se han descrito complicaciones inusitadas derivadas de la colocación de endoprótesis biliares, incluyendo la migración. Se presenta un caso clínico con el objetivo de compartir con la comunidad científica una rara complicación y la única publicada, secundaria a la migración de un stent biliar. Caso clínico: mujer de 47 años de edad, con estenosis de ámpula de Vater benigna, a quien se le colocó endoprótesis biliar, con la cual mejoró clínicamente. Posterior a la colocación del stent se le realizó colecistectomía abierta con exploración de vías biliares. Al año y medio posterior a la colocación del stent, la paciente presentó dolor vago en abdomen bajo y disuria; se le practicaron estudios de imagen donde se observó un extremo del stent biliar en colon sigmoides y otro en vejiga. Se realizó intervención quirúrgica encontrando fístula colovesical, la cual se resolvió en un solo tiempo quirúrgico. La paciente fue egresada con resultados satisfactorios.
BACKGROUND: The endoscopic placement of endoprostheses to decompress biliary obstruction is a commonly used treatment for malignant biliary diseases and is also used in the treatment of benign biliary strictures. Unusual complications of endoprosthesis placement have been described and include the migration of the stent. We present a case to share with the scientific community, an unusual complication secondary to the migration of a biliary stent that has not previously been reported to our knowledge. CASE REPORT: We present the case of a 47-year-old female with a diagnosis of benign papillary stenosis. The patient received a biliary endoprosthesis with clinical improvement. Later she underwent open cholecystectomy and common duct exploration. At consultation 18 months later, the patient presents with indistinct lower abdominal pain and dysuria. We performed imaging studies where the biliary stent was observed, partly in the sigmoid colon and partly in the bladder. The patient underwent surgery where a colovesical fistula was found and treated during the same surgical event. The patient was discharged succesfully.
