Small bowel obstruction following laparoscopic Roux-en-Y gastric bypass: is it always necessary to operate? A 5-year, high volume center experience.

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.
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
purposeThis study aims to describe the incidence, associated factors, etiology, and management of small bowel obstructions following laparoscopic Roux-en-Y gastric bypass (LRYGB).
methodsA retrospective analysis was conducted between January 15 and December 19 using the surgery database of our hospital. Included LRYGB patients were those that evolved with a prolonged length of stay; readmission; emergency room consult; and re-intervention due to small bowel obstruction (SBO) related symptoms with compatible radiological or intraoperative findings. The LRYGB technique implied an antecolic alimentary limb reconstruction and systematic closure of mesenteric defects. Descriptive and analytical statistics were carried out, using a parametric or non-parametric approach as needed.
resultsNine hundred forty-one LRYGB were performed. 9.9% were revisional surgeries of patients with a laparoscopic sleeve gastrectomy. During the study period, 36 SBOs occurred, representing 3.8% of operated patients, with no mortality. 58.3% had successful non-operative management, while 41.7% required surgical exploration, of which 73.3% were treated laparoscopically and 20% needed conversion to open surgery. Etiologies of SBO were jejuno-jejunostomy (JJO) related stenosis (22, 61.1%), internal hernias (6, 16.7%), adherences (3, 8.3%), and other diagnoses (5, 13.9%). Regarding JJO stenosis and internal hernias, median time to diagnosis was 8 days (IQR 7-11) and 12 months (IQR 8.7-16) respectively. Previous sleeve gastrectomy, age, or sex was not associated to the incidence of small bowel obstruction.
conclusionsLRYGB is safe when performed by experienced surgeons. SBO due to internal hernias were scarce in this series. JJO stenosis could explain most cases of SBO; under this diagnosis, non-surgical management was successful frequently.
