The natural history of perforated marginal ulcers after gastric bypass surgery.

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
introductionAlthough perforated marginal ulcers (pMU) following Roux-en-Y Gastric Bypass (RYGB) represent a surgical emergency, the epidemiology and outcome of this condition is not well understood. The purpose of this study was to evaluate incidence of pMU following RYGB and assess the natural history of this complication.
methodsThe SPARCS administrative database was used to identify patients undergoing RYGB between 2005 and 2010. With the use of a unique identifier, we followed patients up to 2014 for subsequent admission and re-intervention (repair or revision) for perforated MU. Groups were compared using Chi square tests with exact p values based on Monte Carlo simulation, t test with unequal variances, and the Wilcoxon rank-sum test when appropriate.
resultsWe identified 35,080 RYGB patients; 292 patients (0.83%) developed pMU 937 (443-1546) days following RYGB [Median (Q1-Q3)]. Among these 292 patients, tobacco use was present in one-third of patients. Repair of the perforation was performed in 115 patients, while anastomotic revision was reported in 64. Patients who underwent revision were more likely to have respiratory complications. Hospital length of stay was significantly longer for patients managed with RYGB revision (Median, Q1-Q3:7, 5-14, vs 6, 4-7, days, p = 0.001). Recurrence of marginal ulcer was common after either intervention (26.09% for repair and 29.69% for revision, p = 0.726).
conclusionFollowing RYGB, the incidence of pMU is small. Anastomotic revision for pMU is associated with prolonged length of stay compared to repair alone. Importantly, recurrence after intervention of pMU is common, suggesting possible value of a routine surveillance program for patients following pMU.
