Leak Pressure After Reinforcement in Gastric Specimens

NCT02272907 · Status: WITHDRAWN · Phase: NA · Type: INTERVENTIONAL

Last updated 2018-06-12

No results posted yet for this study

Summary

The investigators hypothesize that staple line reinforcement will result in a higher leak pressure than a non-reinforced staple line closure in the resected gastric specimens from laparoscopic sleeve gastrectomy. The primary endpoint of the study is leak pressure after various staple line treatments. The investigators will also analyze the most common site of specimen leak, association of stomach thickness to leak, association of stomach thickness to performance of the staple line techniques, and a cost analysis.

Conditions

Interventions

OTHER

Injection of saline solution into specimen to test bursting pressure.

A 1 cm gastrotomy will be made with a purse-string suture placed around the defect. A fluid-instillation catheter will be inserted into the specimen via the gastrotomy. The purse-string suture will then be secured around the catheter. The catheter will be fenestrated with a flange to prevent leakage from the gastrotomy site. The catheter will be attached to a Biopac pressure-monitoring device to monitor pressure within the lumen of the specimen. The specimen will then be suspended in a water bath and methylene blue saline solution will be injected into the specimen to a pressure reading of 0. This will be time zero for our experiment. Methylene blue saline solution will then be injected steadily in incremental levels. During this process, the study team will observe for any obvious blue dye leaks at the staple line or drop in pressure on the monitor.
