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

backgroundThe current management of choledocholithiasis remains a controversial topic. Popular options for treatment include preoperative endoscopic retrograde cholangiopancreatography (ERCP) with endoscopic sphincterotomy (EST) followed by laparoscopic cholecystectomy (LC), or LC and laparoscopic common bile duct exploration (LCBDE) with T-tube decompression. Some concerns suggest that sphincterotomy has significant long-term complications as a result of sphincter of Oddi (SO) dysfunction, and T-tube decompression is historically associated with many complications and discomfort. The purpose of this study was to demonstrate our simple, safe techniques of LCBDE without a T-tube and with an intact SO.

methodsBetween April 2006 and July 2009, a total of 44 selected patients with common bile duct (CBD) stones underwent laparoscopic exploration at our institution. Of 44 laparoscopic choledochotomies, primary choledochorrhaphy was performed on patients with preoperatively installed endoscopic retrograde biliary drainage (ERBD) tubes (n = 10, 22.73%) or endonasobiliary drainage (ENBD) tubes (n = 10, 22.73%) and on patients with intraoperative biliary drainage C-tubes (n = 9, 20.45%) or pigtail J biliary drainage tubes (n = 15, 34.09%).

resultsThe mean operating time for the ENBD, ERBD, J-tube, and C-tube groups were 97.8, 96.2, 102.1, and 98.7 min, respectively. There were no conversions to open surgery, and no intraoperative complications were experienced in any group. CBD clearance was achieved in 43 patients (97.73%). The mean lengths of follow-up for the ENBD, ERBD, J-tube, and C-tube groups were 27.0, 26.7, 23.8, and 30.4 months, respectively; and none of the patients developed major biliary complications including recurrent stones.

conclusionsLaparoscopic primary closure with internal and external biliary drainage tubes is safe and an effective alternative to T-tube placement, especially for younger patient groups able to endure bile duct exploration. Sphincter of Oddi function is well preserved to prevent recurrent bile duct stones and bile duct cancer. Procedures are safe with great feasibility.
