Laparoscopic anterior gastroplasty. A preliminary report of a new technique.
BACKGROUND
The treatment of the morbidly obese patient is difficult because compliance with dietary regimens is poor. As a result, most weight reduction programs fail very quickly. Surgical treatment, on the other hand, provides a reliable method for sustained weight reduction. The most frequently performed procedure has been the vertical banded gastroplasty. Adaptation of the standard open procedure to laparoscopic techniques has been technically difficult and imprecise. We have developed, in the laboratory, an anterior wall banded gastroplasty that can be performed precisely and reproducibly using laparoscopic techniques.


METHODS
Five Yorkshire pigs were used in attempt to laparoscopically perform the standard vertical banded gastroplasty. The procedure was difficult and was associated with a risk of staple line leak and with bleeding along the lesser curvature of the stomach. Furthermore, a reproducible pouch of proper dimension could not be created reliably. Fifteen animals were then used to develop a new technique using a small gastric pouch based on the anterior gastric wall.


RESULTS
A reproducible pouch, 4 cm in length, was created over an 18-Fr nasogastric tube. A standard polyproylene band of 5.2 cm in length was utilized at the gastric pouch outlet.


CONCLUSIONS
This operation can be reproduced accurately and has not demonstrated any leaks on postmortem examination.
