OBJECTIVETo investigate the clinical characteristics, diagnosis and treatment of digestive tract leakage after orthotopic liver transplantation (OLT).

METHODSSixty-one recipients had digestive tract leakage in early stage after OLT among 1173 cases from January 2000 to December 2010. There were 55 male and 6 female patients, aging from 36 to 61 years, with a median of 45 years. Digestive tract leakage included bile leakage (46 cases), gastric leakage (5 cases), duodenal leakage (1 case), jejunal leakage (4 cases), ileal leakage (1 case) and colon transversum leakage (4 cases). Ten of recipients with gastrointestinal leakage had 1 to 3 times of abdominal surgery before OLT. Abdominal drainage was used in 28 cases with bile leakage, and additionally, endoscopic retrograde cholangiopancreatography, endoscopic nasobiliary drainage and stenting were performed for 8 of them, and surgical neoplasty for another 18 patients with bile leakage. Simple surgical neoplasty of perforation was performed for 13 patients with gastrointestinal leakage, and diverticulectomy and neoplasty for 1 case with duodenal leakage, and partial jejunostomy for one severe jejunal leakage. Nutritional support was administered for all of cases.

RESULTSThe incidence rate of digestive tract leakage in early stage after OLT was 5.20% (61/1173). Intra-operative iatrogenic injury of gastrointestinal tract was occurred in 6 cases with gastrointestinal leakage. After treatment, 11 cases died of multiple organ failure resulted from severe infection, with mortality of 18.0% (11/61), including 4 cases with bile leakage, with the mortality of 8.6% (4/46), and 7 cases with gastrointestinal tract leakage, with the mortality of 46.6% (7/15). The remanent 50 cases through comprehensive treatment with a span of 1 to 3 months recovered and discharged healthily. No digestive tract leakage reoccurred in the follow-up of 6 to 84 months.

CONCLUSIONSThe morbidity of digestive tract leakage in early stage after OLT is low, but its mortality is high, especially for gastrointestinal tract leakage. High dose corticosteroids therapy, history of abdominal operation and intra-operative iatrogenic injury may be high risk factor. Comprehensive treatment is crucial for improving prognosis.
