Successful revision surgery for very late-onset stomal obstruction following Gomez gastroplasty: a case report.
Article in Surgical case reports, 2021. 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
backgroundGomez gastroplasty, which was developed in the 1970s as one of the gastric restrictive surgeries for severe obesity, partitions the stomach using a stapler from the lesser towards the greater curvature at the upper gastric body, leaving a small channel. This procedure is no longer performed due to poor outcomes, but surgeons can encounter late-onset complications even decades after the surgery. Here, we report a case of very late-onset stomal obstruction following Gomez gastroplasty which was successfully treated by revision surgery. CASE PRESENTATION: A 58-year-old man was referred to our institution with sudden-onset nausea and vomiting. He underwent weight loss surgery in the USA in 1979, but the details of the surgery were unclear. Esophagogastroduodenoscopy demonstrated a stoma at the greater curvature of the upper gastric body, and fluoroscopy showed retention of contrast medium in the fundus and poor outflow through the stoma. Abdominal computed tomography revealed a staple line partitioning the stomach. Considering these preoperative investigation findings and the period during which the surgery was performed, the patient was diagnosed with very late-onset stomal obstruction following Gomez gastroplasty. Supporting the preoperative diagnosis, the surgical findings revealed a staple line extending from the lesser towards the greater curvature of the upper gastric body and a channel reinforced by a running seromuscular suture on the greater curvature. Moreover, gastric torsion caused by the enlarged proximal gastric pouch was found. Re-gastroplasty involving wedge resection of the original channel was performed followed by construction of a new channel. Postoperative course was uneventful, and the patient no longer had symptoms of stomal obstruction after revision surgery.
conclusionsRe-gastroplasty was safe and feasible for very late-onset stomal obstruction following Gomez gastroplasty. Accurate preoperative diagnosis based on the patient's interview and the investigation findings was important for surgical planning. A careful follow-up is required to prevent excessive weight regain after revision surgery.
