Weight loss one year after laparoscopic roux-en-Y gastric bypass is not dependent on the type of gastrojejunal anastomosis.
Article in Surgical endoscopy, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
backgroundLaparoscopic roux-en-Y gastric bypass (LRYGB) is the gold standard weight-loss procedure. There are different techniques to perform the gastrojejunal (GJ) anastomosis, but there is no consensus as to which one is superior for weight loss. Our goal in this study was to assess one-year weight loss after LRYGB comparing the three different techniques at our tertiary care center.
methodsThe American college of surgeons (ACS) Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP®) data for Montefiore Medical Center for years 2014-2017 were analyzed. Three surgeons were included in this study; each type of anastomosis was performed by a single surgeon. Patients were included if they underwent primary LRYGB. Patients were designated to one of three different groups depending of the type of gastrojejunal anastomosis performed: hand sewn, circular stapled, or linear stapled. One-year weight loss was assessed as primary endpoint of the study. A descriptive analysis of perioperative variables for each group was included as well.
resultsA total of 1011 patients underwent primary LRYGB. 429 (42.1%) were performed with circular-stapled GJ anastomosis, 433 (42.5%) with a hand-sewn GJ anastomosis, and 149 (14.6%) linear-stapled GJ anastomosis. The median BMI was 46.08 ± 6.43, with no difference between groups (p = .405). Procedure time was 106.70 ± 28.23 min for the circular group, 108.27 ± 28.59 min for the hand-sewn group, and 115.78 ± 36.11 min for the linear group (p > 0.005). There were no significant differences in complications except for the need of postoperative transfusions (p < 0.002). There was no statistically significant difference in %EWL one year after surgery: %EWL was 58.81 ± 16.54 kg for hand sewn, 58.86 ± 14.84 kg for circular, and 59.20 ± 17.58Kg for linear. (p = .595).
conclusionThere is no difference in weight loss one year after LRYGB based on the type of gastrojejunal anastomosis performed.
