Impacts of Gastrojejunal Anastomotic Technique on Rates of Marginal Ulcer Formation and Anastomotic Bleeding Following Roux-en-Y Gastric Bypass.
Article in Obesity surgery, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 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
backgroundMarginal ulceration (MU) and bleeding are possible complications following laparoscopic Roux-en-Y gastric bypass (RYGB). Our institution utilizes three techniques for performing the gastrojejunal anastomosis (GJA), providing a means to compare postoperative MU and bleeding as it relates to GJA technique.
objectivesWe sought to analyze the incidence of MU and bleeding between the 25-mm end-to-end anastomosis (EEA) stapler, linear stapler (LS), and robotic hand-sewn (RHS) GJA techniques.
methodsElectronic health records for all patients who had an upper endoscopy (EGD) after RYGB were queried (2010-2014). Charts were retrospectively reviewed for type of GJA, complications, endoscopic interventions, and smoking and NSAID use.
resultsOut of 1112 RYGBs, the GJA was created using an EEA, LS, or RHS approach in 58.6%, 33.6%, and 7.7% of patients, respectively. 17.4% had an EGD (19.9% EEA, 13.9% LS, and 14.0% RHS). Incidence of MU was 7.3% (9.3% EEA, 4.8% LS, and 5.8% RHS). Rates of EGD and MU were significantly higher after EEA vs. LS GJA (p<0.05). The bleeding rate was 1.5%, [1.1% EEA, 2.1% LS, and 2.3% RHS (p=NS)]. MU within 90 days of RYGB occurred in 4.1%, 0.8%, and 4.7%, respectively (p<0.05 for EEA vs LS only). NSAID and cigarette use were identified in 29.3%, 38.9%, and 60% and 17.2%, 22.2%, and 20%, respectively, for the EEA, LS, and RHS GJA (p=NS).
conclusionThe method of GJA has an impact on rate of MU formation. A GJA fashioned with a 25-mm EEA stapler tends to have higher rates of EGD and MU.
