Gastric body partition to avoid ulcerogenic risk and hypergastrinemia.
BACKGROUND
For treatment of giant perforated peptic ulcers, we hypothesized that partitioning of the gastric body instead of the antrum would prevent hypergastrinemia and minimize ulcerogenic risk. By maintaining part of the acid-secreting gastric body in continuity with the excluded distal stomach, gastrin-secreting cells in the antrum would still be inhibited by gastric acid secretion from the gastric body.


METHODS
We studied (1) gastric body partition with gastrojejunostomy in 8 critically ill patients with giant perforated peptic ulcers and (2) the influence of gastric partition on serum gastrin in 18 dogs with gastric antral partition + gastrojejunostomy, or gastric body partition + gastrojejunostomy, or gastrotomy.


RESULTS
No patient developed major postoperative complications. Serum gastrin levels were normal in 6 patients but showed an abnormal increase in 2 patients 1 month after gastric body partition. Serum gastrin levels had returned to the normal range at postoperative follow-up after 2 years. In the animal study, serum gastrin levels and the number of G-cells in the excluded antrum and acid-secreting parietal cells in the gastric body were increased when evaluated on day 60 postoperatively or after antral partition, compared with preoperative data in the same group. These changes did not occur in the group undergoing partition of the gastric body and the group undergoing gastrostomy. Postoperative serum gastrin levels, and the number of G-cells and parietal cells also was significantly greater in the antral partition group than in the other 2 groups. No ulcer was found in any dog in the gastric body partition and gastrostomy groups, but ulcers occurred in 4 dogs in the antral partition group, all of whom died of ulcer perforation.


CONCLUSIONS
Gastric body partition + gastrojejunostomy is a simple, dependable procedure for patients with perforated giant peptic ulcers. This procedure does not require extreme expertise and can be performed in a very short time, even by a trainee general surgeon in emergency.
