1 · What the graph read from it

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.

2 · The registry

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

backgroundA history of abdominal biliary tract surgery has been identified as a relative contraindication for laparoscopic common bile duct exploration (LCBDE), and there are very few reports about laparoscopic procedures in patients with a history of abdominal biliary tract surgery.

methodsWe retrospectively reviewed the clinical outcomes of 227 consecutive patients with previous abdominal biliary tract operations at our institution between December 2013 and June 2019. A total of 110 consecutive patients underwent LCBDE, and 117 consecutive patients underwent open common bile duct exploration (OCBDE). Patient demographics and perioperative variables were compared between the two groups.

resultsThe LCBDE group performed significantly better than the OCBDE group with respect to estimated blood loss [30 (5-700) vs. 50 (10-1800) ml; p = 0.041], remnant common bile duct (CBD) stones (17 vs. 28%; p = 0.050), postoperative hospital stay [7 (3-78) vs. 8.5 (4.5-74) days; p = 0.041], and time to oral intake [2.5 (1-7) vs. 3 (2-24) days; p = 0.015]. There were no significant differences in the operation time [170 (60-480) vs. 180 (41-330) minutes; p = 0.067]. A total of 19 patients (17%) in the LCBDE group were converted to open surgery. According to Clavien's classification of complications, the LCBDE group had significantly fewer postoperative complications than the OCBDE group (40 vs. 57; p = 0.045). There was no mortality in either group. Multiple previous operations (≥ 2 times), a history of open surgery, and previous biliary tract surgery (including bile duct or gallbladder + bile duct other than cholecystectomy alone) were risk factors for postoperative adhesion (p = 0.000, p = 0.000, and p = 0.000, respectively).

conclusionLCBDE is ultimately the least invasive, safest, and the most effective treatment option for patients with previous abdominal biliary tract operations and is especially suitable for those with a history of cholecystectomy, few previous operations (< 2 times), or a history of laparoscopic surgery.
