Long-Term Follow-up and Risk of Recurrence of Internal Herniation after Roux-en-Y Gastric Bypass.
Article in Obesity surgery, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
purposeInternal herniation (IH) is the most common complication after Roux-en-Y gastric bypass surgery (RYGB). Although primary closure has reduced the incidence, recurrences are a continued problem. This study aimed to investigate long-term follow-up and recurrence risk of IH surgery.
methodsA retrospective cohort study of laparoscopic RYGB operated patients operated for a first IH between April 2012 and April 2015 at Skåne University Hospital in Malmö, Sweden. Status of primary closure of mesenteric gaps, time since RYGB, and findings at IH surgery were retrieved from medical records. Follow-up until December 31st, 2019, included recurrences of IH, number of computed tomography (CT) scans, emergency visits, readmissions, and other acute surgeries.
resultsIH (n = 44) occurred almost equally in Petersen's space (n = 24) and beneath the jejunojejunostomy (n = 20). Long-term follow-up (median 75 months) of 43 patients registered an IH recurrence rate of 14% (n = 6). All recurrences occurred in the other mesenteric gap. One patient suffered a third IH, and one patient had four IH events. During follow-up, 56% (n = 24) had ER visits for abdominal pain, 47% (n = 20) had ≥ 1 abdominal CT scan, and 40% (n = 17) were readmitted. A third of readmitted (6/17) patients suffered a recurrence of internal herniation. Two other patients were readmitted ≥ 10 times for chronic abdominal pain.
conclusionSurgery for IH had a low risk of recurrence at the treated mesenteric gap, but a 14% recurrence risk at the other mesenteric gap, emphasizing the importance of carefully investigating weaknesses or gaps at the other mesenteric defect during surgery for IH.
