Laparoscopic partial gastric transection and devascularization in order to enhance its flow.
BACKGROUND
Esophagogastric fistula following an esophagectomy for cancer is very common. One of the most important factors that leads to its development is gastric ischemia. We hypothesize that laparoscopic gastric devascularization and partial transection is a safe operation that will enhance the vascular flow of the fundus of the stomach.


METHODS
Our study included eight pigs. Each animal had two operations. In the first one, a laparoscopic gastric devascularization and mobilization took place. Vascular flow was measured previous to the procedure and immediately after it with a laser doppler (endoscopic probe). After three weeks, a second operation took place. We re-measured the vascular flow and sent a sample of gastric fundus for histopathologic evaluation.


RESULTS
The gastric fundus showed signs of neovascularization after both macroscopic and microscopic evaluation. These findings correlated with laser doppler measurements.


CONCLUSIONS
Laparoscopic gastric devascularization and partial transection is a safe procedure that increases the vascular flow of the stomach in a three week period. This finding can have a positive impact in terms of decreasing fistula formation.
