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

backgroundEarly postoperative small bowel obstruction (ESBO) following roux-en-Y gastric bypass (RYGB) is a feared complication, generally estimated to occur in 1-2% of cases. Most surgeons advocate for prompt surgical exploration for ESBO after RYGB. There is currently a paucity of literature regarding conservative management approaches to ESBO after RYGB.

objectivesTo determine the safety and efficacy of non-operative management of early small bowel obstruction following RYGB.

settingAcademic-affiliated municipal hospital.

methodsWe performed a retrospective review of all patients at a single institution who underwent RYGB between July 1, 2020 and April 30, 2024 and were readmitted within 30 days of the procedure due to a small bowel obstruction. Mesenteric defects were closed with permanent suture in 100% of cases.

results2430 RYGBs were performed, 54 patients (2.2%) developed ESBO. The average interval from time of surgery to diagnosis of ESBO was 7.3 days [range 2-26 days]. The vast majority of patients (n = 43; 80%) were successfully managed conservatively including nasogastric decompression (n = 20; 47%). Most (73%) of the patients requiring reoperation were found to have kinking at the anastomosis or dense adhesions from the cut end of the staple line.

conclusionsThis study demonstrates that non-operative management may be a safe and effective treatment option for the majority of RYGB patients who develop ESBO. Clinical judgement is required to identify those who would benefit from early exploration.
