The application of vascularized stomach flap to repair postoperative biliary stricture.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Hepaticojejunostomy, which is the "gold standard" procedure for repairing postoperative biliary strictures, predisposes patients to reflux cholangitis from loss of sphincter of Oddi. The aim of this study was to assess the sphincter-preserving biliary reconstruction approach to repair postoperative biliary stricture. An autologous vascularized stomach flap was prepared and used to repair biliary defect caused by postoperative biliary stricture. Patient clinical data were analyzed retrospectively and long-term prognosis was evaluated based on the Lillemoe standard. Twenty-eight patients who underwent surgery from 2002 to 2010 were enrolled for the study. The original surgical procedure that caused biliary stricture consisted of patients having cholecystectomy (n = 22), biliary duct exploration (n = 5), and hepatectomy (n = 1). Eighteen (64%) of the 28 patients had previous repair surgery before being admitted. Based on the Bismuth level, 7 were classified as type I, 15 as type II, and 6 as type III. The mean length of biliary defect determined preoperatively by magnetic resonance cholangiopancreatography was 1.5 cm. The surgical procedure was successfully performed for all patients with a mean operation time of 261 ± 47.8 minutes. The postoperative complication rate was 10.7%, including minor bile leak (n = 2) and pulmonary infection (n = 1). There was no perioperative deaths. Two patients were absent during follow-up, and the remaining 26 patients had a mean follow-up period of 7.5 years (61-155 months). Twenty-four patients remained healthy during the follow-up period, while 2 patients (7.7%) had sporadic recurrent cholangitis that eventually resolved spontaneously. The overall long-term outcome rate was 92.3%. None of the patients had recurrence of stricture during the follow-up period. These results suggest that biliary repair using vascularized stomach flap could reduce reflux cholangitis and offer a satisfactory long-term outcome. This procedure could be a reliable method to repair postoperative biliary stricture with limited biliary defect.
