Gastric bypass pouch and stoma reduction using a transoral endoscopic anchor placement system: a feasibility study.
Article in Surgical endoscopy, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02302898 (Characteristics Associated With Weight Regain After Roux-en-Y Gastric Bypass), which is not on this map. Cited by 19 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.

Abstract
backgroundWeight regain after Roux-en-Y gastric bypass may be caused by pouch enlargement or dilatation of the gastrojejunostomy (stoma). In order to avoid the substantial morbidity of revisional bariatric surgery, investigators have recently demonstrated the feasibility of reducing stoma diameter using transoral endoscopic suturing techniques. Our aim was to demonstrate the feasibility of performing both pouch and stomal reduction using transoral endoscopically placed tissue anchors in an ex vivo and acute animate model.
methodsPart I: We created an ex vivo model of a dilated gastric pouch and stoma using four explanted porcine stomachs. The stomach was divided to create an upper pouch of approx. 100 ml volume, which was reconnected to the lower portion of the stomach (gastric remnant) via an anastomosis of 18 to 20 mm diameter. Endoscopically placed anchors were then used to create plications of the stoma and reduce its diameter. In two stomachs, anchor plications were also used to decrease pouch volume. Pouch volumes and stoma diameters were measured pre- and post-procedure. Part II: A similar experimental model was created in vivo using three pigs. Anchors were placed in the stoma and pouch. The animals were immediately sacrificed and similar measurements were obtained.
resultsIn the ex vivo model, stoma diameter was successfully reduced in all four stomachs by a mean of 8 mm (41%). This represented a mean decrease in cross-sectional area of 65%. Pouch volume was reduced by a mean of 28 ml (30%) in two stomachs. Stomal plications were successfully placed in two of the live animals, with a mean stoma diameter reduction of 11.5 mm (53%). Feasibility of pouch reduction using plicating anchors was confirmed.
conclusionsThis is the first study to demonstrate the feasibility of using endoscopically placed tissue anchors to reduce both stoma diameter and pouch volume. This technique may ultimately be clinically useful in treating weight regain after gastric bypass surgery.
