Background: There is a paucity of data regarding the safety and efficacy of percutaneous endoscopic gastrostomy with jejunal extension (PEG-J). We evaluated adverse events related to PEG-J and determined the clinical impact of PEG-J in those with chronic pancreatitis (CP).Methods: This cohort study included all patients who underwent PEG-J placement in a tertiary-care academic medical center between 2010 and 2012. Main outcome measurements were (1) short- and long-term complications related to PEG-J and (2) changes in weight and hospitalizations during the 12-month period before and after PEG-J in the CP subgroup.Results: Of 102 patients undergoing PEG-J placement, the overall technical success rate was 97 %. During a median follow-up period of 22 months (1-46 months, n = 90), at least one tube malfunction occurred in 52/90 (58 %; 177 episodes) after a median of 53 days (3-350 days), requiring a median of two tube replacements. Short-term (<30 days) tube malfunction occurred in 28/90 (31 %) and delayed in 24/90 (27 %); these included dislodgement (29 %), clogging (26 %) and kinking (14 %). In the CP subgroup (n = 58), mean body weight (kg) (70 vs. 71, p = 0.06) and body mass index (kg/m2, 26 vs. 27, p = 0.05) increased post-PEG-J. Mean number of hospitalizations (5 vs. 2, p < 0.0001) and inpatient days per 12 months (22 vs. 12, p = 0.005) decreased.Conclusions: While we observed no major complications related to PEG-J, half of patients had at least one episode of tube malfunction. In the CP subgroup, jejunal feeding via PEG-J significantly reduced the number of hospitalizations and inpatients days, while improving nutritional parameters. [ABSTRACT FROM AUTHOR]

Background. There is little prospective data on whether bigger plastic stents are better for patients with malignant biliary obstruction with jaundice. Goals. Multicenter prospective study to compare technical success, clinical response, stent occlusion, and patient survival in patients with malignant biliary obstruction randomized to 10-French or 11.5-French plastic stent. Study. Patients with malignant biliary obstruction were randomized to 10-French or 11.5-French biliary stents. Patients were prospectively assessed for stent occlusion, stent-related interventions, hospital stay, and change in bilirubin. Main outcome measurements included technical success, clinical response, rates of stent occlusion, and survival. Results. 234 patients (47 hilar and 187 common bile duct strictures) were randomized. Outcomes were similar for the 10-French and 11.5-French groups (technical success 99.1% versus 97.4%, p = 0.37). Overall, median stent survival was 213 days, but there was no statistically significant difference in stent survival between 10-French and 11.5-French stents (149 versus 258 days, p = 0.16). Stent survival was significantly longer when placed for common bile duct versus hilar strictures (231 versus 115 days, p = 0.049). Conclusions. The theoretical advantage of improved bile flow for the 11.5-French stent does not translate into more prolonged patency, better clinical response, and longer patient survival than the 10-French stent.

Traditionally, patients with symptomatic sterile pancreatic necrosis or infected necrosis have been managed by open surgical debridement and removal of necrotic tissue. Within the last decade, however, reports of endoscopic pancreatic necrosectomy, an alternative minimally invasive approach, have demonstrated high success rates and low mortality rates. This report describes the indications, technique, and study outcome data of the procedure. While our experience with this technique has recently increased, better selection criteria are needed to identify patients who are most suitable for endoscopic therapy. [ABSTRACT FROM AUTHOR]
