ABSTRACT Objective: To determine the efficacy and safety of double guidewire technique in patients with difficult biliary cannulation during ERCP. Materials and methods: We conducted a retrospective cohort study of all ERCPs performed between January 2015 and July 2016. DGT was performed in patients for whom biliary cannulation was difficult and guidewire insertion into the pancreatic duct (PD) was inadvertently achieved while attempting the standard WGC technique. Results: 24 patients were enrolled with ERCP and DGT; 17 were female (70.8%) and 7 male (29.2%). The average age was 65.21±16.49 years. The most frequent indication was choledocholithiasis (62.5%), then cholangiocarcinoma (12.5%). Post ERCP diagnosis was choledocholithiasis (45.8%), and papillary fibrosis (29.2%). The success of DGT was 87.5%. Three cases of failure cannulation with the DGT were reported, two patients had pancreatitis post ERCP (8.3%), there were no cases of perforations. Conclusions: TDG, is an effective alternative to difficult biliary cannulation during ERCP with conventional methods; with a high success rate and low rate of post ERCP pancreatitis, similarly to reported in other countries.

Pancreatite aguda de etiologia desconhecida / Acute pancreatitis of unknown etiology

A pancreatite aguda (PA) é responsável por aproximadamente 210 mil hospitalizações por ano nos EUA, e cerca de 5% evoluem ao óbito. Após o primeiro episódio a conduta fundamental é identificar e tratar a causa, o que impedirá episódios recorrentes e mesmo a cronicidade da doença.

The acute pancreatitis (AP) is responsible for approximately 210,000 of hospitalizations in a year in USA, and about 5% lead to death. After the first episode, the mainly procedure to be adopted is to identify the cause of it and consequently treat it as well, which will block recurrent episodes and prevent that this ilness becomes chronic.

Role of Balloon-Sheathed Intraductal Ultrasonography for Patients with Extensive Pneumobilia

Intraductal ultrasonography (IDUS) is one of the most useful diagnostic tools for various extrahepatic biliary diseases. However, conventional IDUS has some limitations in providing accurate cross-sectional imaging of the bile duct in patients with extensive pneumobilia. Using a balloon-sheathed catheter, the US system (balloon-sheathed IDUS) can overcome these limitations. Sixteen patients underwent balloon-sheathed IDUS during endoscopic retrograde cholangiography. The balloon-sheathed IDUS was inserted via a transpapillary route when visualization of the bile duct with conventional IDUS was distorted by extensive pneumobilia. The patient group had a mean age of 65.5 years, and 56.3% (9/16) were male. The balloon-sheathed IDUS permitted successful visualization of the bile duct in all patients, regardless of the extent of pneumobilia. Using this system, remnant common bile duct stones were detected in five patients (31.3%), and cholangiocarcinoma was detected in one patient (6.3%). The balloon-sheath IDUS aided in stone sweeping. No significant complications, including bleeding, perforation, or pancreatitis, occurred in any of the patients. The balloon-sheathed catheter US system was useful and safe for biliary IDUS in patients with extensive pneumobilia.

Fibrinógeno-trombina como tratamiento puente en un caso de hemoptisis masiva / Fibrinogen-thrombin as bridge therapy in massive hemoptysis

Se presenta el caso de una paciente joven con hemoptisis masiva por tuberculosis que no pudo ser controlada de forma efectiva con la inserción de un catéter Fogarty por un fibrobroncoscopio. Ante esto y el alto riesgo de asfixia o desangramiento, se decidió infundir fibrinógeno-trombina a través de un catéter, introducido por el fibrobroncoscopio; con esto se logró controlar el sangrado, intubarla con un tubo orotraqueal de doble luz y estabilizarla para remitirla a otra institución, donde fue sometida a lobectomía y se le proporcionó tratamiento antituberculoso. La infusión de fibrinógeno-trombina podría considerarse como una opción terapéutica transitoria, de tipo puente, mientras se practica el manejo definitivo.

This article presents the case of a young woman with massive hemoptysis (1,000 mL in 6 hours) due to tuberculosis, which could not be controlled by insertion of a Fogarty catheter through a fiber-optic bronchoscope. Because of asphyxia and persistent bleeding risk we instilled fibrinogen-thrombin through a fiber-optic bronchoscope inserted catheter, achieving bleeding cessation and permitting the placing of a double-lumen oro-tracheal tube. Later on, the patient underwent lobectomy and anti-tuberculosis treatment. The fibrinogen-thrombin could be considered as a bridge, transitory measure for massive hemoptysis, while definitive treatment could be established.

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.

Colangiopancreatografía endoscópica retrógrada: análisis de sus complicaciones / Endoscopic retrograde cholangiopancreatography: complication analysis

El objetivo del estudio es el análisis de las complicaciones surgidas de la realización de la colangiografía endoscópica retrógrada (ERCP) y sus procedimientos asociados. Se estudian 677 procedimientos endoscópicos realizados por el autor durante un período de 4 años. De éstos, en 304 se efectuó además una papilotomía, 100 requirieron de una maniobra de pre cut previo a la canulación, mientras que en 83 el procedimiento fue efectuado en pacientes previamente papilotomizados. En 84 pacientes se requirió de la inserción de una prótesis endoscópica. La indicación para la ERCP más común fue coledocolitiasis: 346 (51 por ciento), dilatación de la vía biliar en 57 (8,4 por ciento) y la sospecha de una neoplasia en 41 (6 por ciento) pacientes, respectivamente. Nueve pacientes presentaron complicaciones (1,3 por ciento). Esta serie confirma el tipo de complicaciones habitualmente descrita para la ERCP. Por otra parte, destaca la ausencia de perforación y sangrado en la serie. Se confirma la seguridad del método, pero también se hace presente la potencial aparición de complicaciones graves muchas de ellas independientes de las características del procedimiento

Precut papillotomy using needle knife fashioned from discarded standard papillotomes.

AIM: To evaluate the results of precut papillotomy using needle-knife papillotomes fashioned from discarded standard sphincterotomes. METHODS: Case records of 50 patients undergoing precut papillotomy for access to either common bile duct or pancreatic duct during endoscopic retrograde cholangiopancreatography were reviewed. Precut was performed using needle-knife papillotomes fashioned from standard pull-type sphicterotomes that were discarded because of broken cutting wires. A diagnostic procedure was planned in all 50 patients (bile duct = 39, pancreatic duct = 9, both ducts = 2) and therapeutic procedure in 36 patients (bile duct = 31, pancreatic duct = 5). RESULTS: Of the 47 patients who needed precut prior to diagnostic ERCP, 44 (93.6%) underwent successful cannulation of the duct of choice. Therapeutic procedures were planned in 36 patients; these were successful in 24 (67%; bile duct = 22, pancreatic duct = 2). The complications included cholangitis in 8 patients (16%) and pancreatitis in 2 (4%). None had bleeding or perforation. CONCLUSIONS: Precut needle-knife papillotomes fashioned from discarded standard sphincterotomes can be used effectively and can help in cost containment in endoscopic retrograde cholangiopancreatography.

Endoscopic management of pancreatic diseases.

Endoscopic management has recently been used for a variety of chronic pancreatic diseases. We used this approach in five patients with pancreatic diseases (calcific pancreatitis 2, pancreatic pseudocyst 3). Nasocystic drain was placed in a patient with pancreatic pseudocyst at the tail end of the pancreas; a 5 Fr stent was placed over 0.021"/0.035" guide wire in the main pancreatic duct in the others. All patients had relief of pain. Nasocystic drain led to resolution of pseudocyst, perisplenic collection and pleural effusion. Endoscopic treatment is safe and effective in various pancreatic disorders.

ERCP in situs inversus: do we need to turn the other way?

Endoscopic procedures are difficult in patients with situs inversus owing to left-right reversal of viscera. Conventionally, reversal of the position of the endoscopist in relation to the patient is advocated to overcome the anatomical difficulty. We describe a patient with chronic calcific pancreatitis and pseudocyst of the pancreas who had situs inversus. ERCP was performed with minor modification of maneuvers with the patient in the usual left lateral decubitus and the endoscopist on the left of the table.
