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

backgroundSeveral different procedures have been proposed as a revisional procedure for treatment of failed laparoscopic adjustable gastric banding (LAGB). Laparoscopic Roux-en-Y gastric bypass (LRYGB) has been advocated as the procedure of choice for revision. In this study, we compare the single- and two-step approaches for the revision of failed LAGB to LRYGB.

methodAll patients who underwent bariatric surgery were included in a prospective database. For the purpose of this study, patients who underwent revisional surgery from LAGB to LRYGB were selected. Records for individual patients were completed by data review. Complication rates and weight development were recorded until 2 years postoperatively. Data were compared between both procedures and with complications rates reported in literature.

resultsRevisional gastric bypass surgery was performed in 257 patients. This was done as a planned single-step procedure in 220 (86 %) patients without indications for acute band removal and in 32 patients as a planned 2 step procedure. Five patients were planned as a single-step procedure but were intraoperatively converted to a 2-step procedure based on poor pouch tissue quality. No postoperative mortality occurred in both groups. No differences in early major morbidity and stricture formation were seen between the two groups. Gastric ulceration was more frequently observed after 2-steps procedure (8.5 vs. 1.7 %, p < 0.05). In comparison with data reported in literature, the single-step procedure had similar to lower complication rates. Percentage excess weight loss two years after revisional gastric bypass procedure was, respectively, 53 versus 67 % (p = 0.147) for single- and two-step procedure.

conclusionIn patients without indications for acute band removal, the planned conversion of gastric banding to Roux-Y gastric bypass can be safely done in a single-step procedure without increase in morbidity and no difference in postoperative weight loss.
