ABSTRACT
BACKGROUND: Management of Sphincter of Oddi Dysfunction (SOD) requires advanced techniques (endoscopic retrograde cholangiopancreatography via gastrostomy [GERCP]) after Roux-en-Y gastric bypass (RYGB) for obesity. Transduodenal sphincteroplasty (TS) is also performed yet carries the risks of surgery. We hypothesized that TS would have increased morbidity and mortality but provide a more durable remission of symptoms. METHODS: All patients between 2005 and 2016 with RYGB for obesity undergoing endoscopic or surgical management for type I or II SOD were included in the study. Patients with type III SOD, or who underwent RYGB for nonobesity indications, were excluded. RESULTS: Thirty-eight patients were identified. GERCP was initially performed in 17 patients, whereas TS was performed in 21. Thirty-day mortality was 0% in our cohort, and 30-d morbidity was similar between GERCP and TS (29% versus 10%; P = 0.207). Resolution of symptoms after initial therapy was seen in 41% of GERCP (7/17) and 67% of TS (14/21) (P = 0.190), respectively, and overall after 35% (8/23) and 64% (16/24) of procedures performed (P = 0.042). Symptom resolution, as defined by the median ratio of days of total remission by total days of observed follow-up, was shorter after initial and all interventions with GERCP compared with TS (0.67 versus 1.00, P = 0.036 and 0.52 versus 1.00, P = 0.028, respectively). CONCLUSIONS: Endoscopic and surgical treatment of SOD had similar morbidity and mortality. However, treatment success and duration of remission was higher in those treated with surgery.

OBJECTIVES: Biliary complications are common after living-donor liver transplant. This retrospective study reviewed our experience with biliary complications in recipients of living-donor liver transplant. MATERIALS AND METHODS: Over our 9-year study period, 120 patients underwent living-donor liver transplant. Patients were divided into 2 groups, with group A having biliary complications and group B without biliary complications. Both groups were compared, and different treatment modalities for biliary complications were evaluated. RESULTS: Group A included 45 patients (37.5%), whereas group B included 75 patients (62.5%). Biliary complications included bile leak in 17 patients (14.2%), biliary stricture in 11 patients (9.2%), combined biliary stricture with bile leak in 15 patients (12.5%), and sphincter of Oddi dysfunction and cholangitis in 1 patient each (0.8%). Cold ischemia time was significantly longer in group A (P = .002). External biliary drainage was less frequently used in group A (P = .031). Technical success rates of endoscopic biliary drainage and percutaneous transhepatic biliary drainage were 68.3% and 41.7%. Survival rate following relaparotomy for biliary complications was 62.5%. CONCLUSIONS: Graft ischemia is an important risk factor for biliary complications. Bile leaks can predispose to anastomotic strictures. The use of external biliary drainage seems to reduce the incidence of biliary complications. Endoscopic and percutaneous trans-hepatic approaches can successfully treat more than two-thirds of biliary complications. Relaparotomy can improve survival outcomes and is usually reserved for patients with intractable biliary complications.
