Knotless tissue control devices for hand-sewn gastrojejunostomy in robotic-assisted Roux-en-Y gastric bypass.
Article in Obesity surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundLiterature on clinical and economic outcomes with hand-sewn gastrojejunostomy using Spiral Antibacterial Knotless Tissue Control Devices (KTCD) in Roux-en-Y gastric bypass (RYGB) is scant.
objectivesAssess clinical and economic outcomes of patients receiving KTCD for hand-sewn gastrojejunostomy vs. alternative means of anastomosis in robotic-assisted RYGB.
settingUS hospital.
methodsPatients who received gastrojejunostomy using KTCD in robotic-assisted RYGB between 01/01/2020-08/31/2023 identified in the Premier Healthcare Database (PHD) were evaluated via medical chart review (RYGB=index). Patients with alternative means of anastomosis, including non-KTCD sutures/staplers, in robotic-assisted RYGB in the PHD during the same timeframe were utilized as controls. Optimization-based stable balance weighting balanced the cohorts on baseline characteristics. Outcomes included a composite complication measure (anastomotic leak, bleeding, dilation of small intestine, infection, pelvic abscess, ileus/bowel obstruction) evaluated at index, index through 30 days and 90 days, anastomotic leak through 90 days, length of stay (LOS), and index costs.
results145 patients in two hospitals met KTCD selection criteria; 6,491 met control criteria. Incidences of complications at index, 30 days, and 90 days were lower for KTCD vs. controls (0.7% vs. 4.5%, 0.7% vs. 7.3%, 2.1% vs. 8.3%; all p<0.01). LOS was shorter for KTCD vs. controls (1.34 vs. 1.62 days; p=0.002). Anastomotic leaks (1.4% vs. 2.0%; p=0.143) and index costs ($17,042 vs. $16,431; p=0.494) did not differ between KTCD vs. controls.
conclusionsThis retrospective analysis of gastrojejunostomy in robotic-assisted RYGB found fully hand-sewn gastrojejunostomy with KTCD was associated with lower complication rates and shorter LOS vs. alternative means of anastomosis.
