RESUMEN
La denominada cirugía bariátrica Bypass Gástrico es una de las operaciones bariátricas mayormente efectuadas a nivel mundial y en aumento en años recientes. La exclusión del estómago y duodeno, después del procedimiento, deja con gran dificultad, la ejecución vía oral, de la Colangiopancreatografía endoscópica (CPRE) y el acceso al tracto biliar y pancreático. Debido a la incrementada incidencia de litiasis biliar en pacientes luego del procedimiento bypass gástrico, habrá más requerimiento de la Colangiopancreatografía endoscópica. En los últimos años se ha demostrado que los pacientes con bypass gástrico que ameriten evaluar el tracto biliopancreático pueden someterse exitosamente a Colangiopancreatografía endoscópica terapéutica transgástrica asistida por laparoscopia, en forma segura y confiada. Presentamos nuestra paciente con litiasis residual: cálculo impactado en la papila, efectuando la Colangiopancreatografía endoscópica transgástrica asistida por laparoscopia e Fistulotomía con bisturí - aguja por cálculo impactado en la papila, resuelto satisfactoriamente.
The Gastric Bypass is one of the most performed bariatric operatio ns worldwide, and in recent years the number of former bypass patients accrues. The gastric bypass excludes the stomach and duodenum, and it makes very difficult, by oral route, the access to the biliopancreatic tract, by means the endoscopic retrograde cholangiopancreatography (ERCP). Due to the increased evidence of gallstones after bariatric operations, the ERCP could be more often required. In recent years, it has been demostrated that gastric bypass patients can be successfully evaluated endoscopically by laparoscopic transgastric ERCP, as a safe and reliable method. We describe a patient with residual billiary impacted stone in the papilla, who underwent laparoscopic transgastric ERCP and a precut fistulotomy technique with needle - knife, was highly successful, without add significant morbidity to the procedure.
RESUMEN
Objective To evaluate the effect of pre-cut-endoscopic mucosa resection of colorectal laterally spreading tumor. Methods 65 patients with LST were enrolled from January 2014 to February 2014. LST was detected by chromoendoscopy and NBI combined with magnifying endoscopy technique. The size, site, morphological features, were observed and the histopathological features of the specimen of LST was analyzed. All the 65 LSTs were resect by pre-cut-EMR. The clinical results including enbloc resection rate, all bloc resection rate, procedure time, complication and recurrence rates were retrospectively evaluated. Results All the 65 LSTs lesions ranged from 2.0 cm to 5.0 cm, with a mean diameter of (2.4 ± 1.7) cm. The site of 65 LSTs was in rectum 28 (43.1 %), 11 LSTs in sigmoid colon (16.9 %), 6 LSTs in descending colon (9.2 %), 2 LSTs in splenic flexure of colon (3.1 %), 9 LSTs in transverse colon (13.8 %), 4 LSTs in Hepatic flexure of colon (6.2 %), 2 LSTs in ascending colon(3.1 %), and 3 LSTs in cecum (4.6 %). Morphology of 23 LSTs were homogeneous granular type (35.4 %), 27 LSTs were mixed non-granular type (41.5 %), 13 LSTs were flat elevated type (20.0 %), and 2 LSTs were pseudo-depressed type (3.1 %). The histopathological diagnoses of LST included 12 tubular adenoma (18.5 %), 19 villous-tubular adenoma (29.2 %), 26 villous adenoma (40.0 %), 7 advanced intraepithelial tumor (10.7 %), 1 intramucosal carcinoma (1.5 %). Enbloc resection was achieved in 65 patients (100.0 %) with a mean operation time of (18.0 ± 11.7) min. 5 cases were bleeding during the operation (7.7 %), 1 case was bleeding 7 days after operation (1.5 %), no perforation was happened. 65 patients were followed up for 3 ~ 12 months, and no local recurrence was found. Conclusion Pre-cut-endoscopic mucosal resection an effective and safe therapy for colorectal LST larger than 2.0 cm.
RESUMEN
INTRODUCCIÓN: la canulación profunda de la via biliar principal es requisito para una Pancreato-colangiografía Retrograda Endoscópica (PCRE) de carácter terapéutico. El pre corte es una técnica practicada en casos de canulación difícil. Objetivo: Reportar los casos de pacientes con canulación difícil y fistulotomia suprapapilar como un método para la canulación selectiva del colédoco. Reportar la eficacia, hallazgos demográficos, endoscópicos y complicaciones de éste procedimiento. MATERIAL Y MÉTODOS: estudio prospectivo, descriptivo y observacional de casos. Se ha realizado en 93 pacientes sometidos a PCRE con canulación difícil en quienes se practicó el pre corte tipo Fistulotomia, en un Centro privado de Endoscopia Digestiva del 2000 al 2010 en Lima. RESULTADOS: En 1205 (100%) CPRE se hicieron 1152 (96%) papiloesfinterotomias, de éstos en 93 casos (8%) casos se hizo fistulotomia previa a la papiloesfinterotomia. El grupo atareo más frecuente fue de 61 a 70 años, la relación F:M, 2.4:1. La eficacia fue 96%, los hallazgos endoscópicos más frecuentes fueron Odditis, impactación de cálculo y la presencia de ampuloma, los diagnósticos finales fueron enfermedad litiásica (34%), seguida de la Odditis con o sin litiasis coledociana (29%), en el 75% de casos se realizó terapéutica, el 8.5% de casos presentó complicaciones (pancreatitis y sangrado). No se registró perforaciones ni colangitis. CONCLUSIONES: en esta serie la fistulotomia en casos de canulación difícil es eficaz, es más frecuente en casos de Odditis, cálculo impactado y ampuloma y las complicaciones son bajas. RECOMENDACIONES: el pre corte tipo fistulotomia está dirigida a pacientes que requieren PCRE terapéutica, la decisión de realizarla debe ser precoz, la firma de un consentimiento informado es primordial.
INTRODUCTION: Biliary conducts deep cannulation is a requirement for therapeutic Endoscopic Retrograde Cholangio-Pancreatography (ERCP). The pre-cut papillotomy is a technique for difficult cannulation cases. Aims: Report cases of hard cannulation and suprapapilar fistulotomy as a method for selective common bile duct cannulation. Report efficacy, demographic and endoscopic findings and complications of this procedure. MATERIALS AND METHODS: Observational, descriptive and prospective study of cases. Sample of 93 patients who had a difficult cannulation ERCP, in which suprapapilar fistulotomy pre-cut type was done, in a private digestive endoscopic center between 2000 and 2010 in Lima, Peru. RESULTS: 1205 (100%) ERCP were made 1152 (96%) papillosphincterotomies. Fistulotomy was done in 93 cases (8%) of these papillosphincterotomies. The most prevalent age group was 61 to 70 years old, the female-male proportion was 2.4:1. The efficacy was 96%. The most prevalent endoscopy findings were odditis, gallstone impactation and ampulloma presence, final diagnosis were lithiasic disease (34%), Odditis with or without common bile duct lithiasis (29%). Therapeutic ERCP was done in 75% of the cases, 8.5% showed complications (pancreatitis and bleeding). No perforation or cholangitis were registered. CONCLUSIONS: In this case series, fistulotomy in difficult cannulation procedures had good efficacy. Is most prevalent in cases with odditis, gallstone impactation and ampulloma. Complications of the procedure are low. RECOMMENDATIONS: The fistulotomy type of pre-cut is leaded for patients who require therapeutic ERCP. The decision for doing the procedure must be precocious and informed consent is primordial.
