Internal Hernia After Laparoscopic One-Anastomosis (Mini) Gastric Bypass: Video Case Series of a Single-Center Experience.

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
Internal hernia (IH) after one-anastomosis gastric bypass (OAGB) was thought to have an extremely low incidence. In this video, we report three cases of post-OAGB symptomatic internal herniation. The first case is a 45-year-old female who presented 4 months after her OAGB with crampy abdominal pain and reflux symptoms. An exploratory laparoscopy showed Petersen's hernia; the hernia was reduced with no ischemia and the defect was closed. The second case is a 40-year-old male who presented 7 months after his surgery with abdominal pain and reflux. An exploratory laparoscopy showed Petersen's hernia; bowel was reduced and defect was closed through a laparotomy. The third case is a 64-year-old male who presented with refractory biliary reflux after OAGB. An elective diagnostic laparoscopy showed Petersen's hernia; the hernia was reduced and defect was closed. All patients recovered well with no recurrence of symptoms on follow-up. Internal hernia after OAGB is more common than the reported incidence. The threshold for diagnostic laparoscopy should be lowered for a OAGB patient with symptoms suggestive of IH.
