Per oral pyloromyotomy utilizing a lesser curvature approach: how we do it.

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
backgroundThe treatment of gastroparesis refractory to medical therapy has evolved to include purely endoscopic techniques. Per oral pyloromyotomy (POP) has evolved from traditional laparoscopic or open pyloroplasty to become a safe and effective minimally invasive option for patients with gastroparesis. As compared to laparoscopic pyloroplasty (LP), POP produces similar improvements in gastric emptying and symptom mitigation, while having shorter lengths of stay. There are slight variations in technique that vary by institution. Described here is a technique utilizing a lesser curve approach, with a mucosotomy closure using clips in an effort to maximize efficiency of the procedure.
methodsPreoperative workup includes a scintigraphic gastric emptying study or a wireless motility capsule study, and the Gastroparesis Cardinal Symptom Index (GCSI). After an upper endoscopy, the procedure begins with injection into the submucosal space with methylene blue in saline on the lesser curve, 3-5 cm proximal to the pylorus. A 1.5 cm incision is then made with the ERBE hybrid knife. A submucosal tunnel is created past the distal end of the pylorus, and the muscle is hooked, and divided with the hybrid knife. The mucosotomy is closed with clips (Boston Scientific Resolution 360, Boston, MA) after the completion of the myotomy. Post-operatively, patients are discharged home after an overnight stay with a proton pump inhibitor, sucralfate, and a full liquid diet for 2 weeks.
conclusionsA lesser curve approach with mucosotomy closure using clips is a safe, effective, and efficient modality for performing POP. As more centers adopt POP as a tool for gastroparesis management, the lesser curve method limits the length of the submucosal tunnel needed, and allows for wide adoption of the technique.
