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

backgroundLaparoscopic Roux-en-Y gastric bypass (RYGB) is an effective treatment modality for severe obesity. Failure of weight loss and/or weight regain due to lack of restriction has been reported in long-term follow-up studies. The aim of this study is to determine the safety and effectiveness of reestablishing the restrictive component of the operation by trimming the pouch and/or anastomosis for pouch and/or anastomotic enlargement using a laparoscopic approach.

methodsWe retrospectively reviewed our prospectively collected database for all patients that underwent revisional surgery of RYGB for weight regain or failure of weight loss. Percent excess weight loss (%EWL) and BMI loss (BMIL) were characterized into the following three time periods: (1) primary operation to pre-revision, (2) pre-revision to post-revision, and (3) primary operation to post-revision. Post-operative follow-up was at 6, 12, 18, 24, 36, and 48 months.

resultsBetween 2005 and 2011, a total of 121 patients in the database underwent revision of RYGB. Forty-four patients were identified that fulfilled the aforementioned parameters. In this group, 30 patients underwent trimming of the pouch and/or redo anastomosis (TPA), 8 TPA and conversion from retrocolic to antecolic Roux limb, and 6 TPA with remnant gastrectomy. Mean follow-up period was 26.1 ± 22.7 months. The post-revision mean %EWL was 38%, and the BMI loss was 7 kg/m(2). In the pre-revision to 48 months post-revision time period, mean %EWL and BMIL were 28.6% and 4.9 kg/m(2) in the TPA-only group, 52% and 8.8 kg/m(2) in the TPA with conversion to antecolic, antegastric group, and 33.4% and 5.9 kg/m(2) in the TPA with gastrectomy group, respectively (%EWL, p = 0.096; BMIL, p = 0.227). One patient (2.3%) developed a left upper quadrant hematoma. There was no mortality in this series.

conclusionsTrimming of the pouch and/or anastomosis appears to be a safe and effective revisional modality for patients with insufficient weight loss or weight regain after gastric bypass in the hands of experienced surgeons.
