[A comparative study of CT and barium enema examination in diagnosis of peritoneal metastasis from gastric carcinoma].

Objective: To compare the results of CT and barium enema examination in the diagnosis of peritoneal metastasis from gastric carcinoma.

Materials: Peritoneal metastases were pathologically confirmed in nine patients with gastric carcinoma who had had abdominal CT and barium enema examinations prior to surgery.

Methods And Results: Five patients were reported to have colonic wall rigidity on preoperative barium enema examination.

A case of incarcerated lesser sac hernia protruding simultaneously through both the gastrocolic and gastrohepatic omenta.

Small bowel obstruction due to lesser sac herniation through both the gastrocolic and gastrohepatic omenta is extremely rare, and only a few reported cases have been concerned with imaging diagnosis. CT images showed distended bowel loops at the level of the cephalad part of the stomach, collapsed triangular loops and attached mesentery were depicted just behind the caudal part of the stomach. These findings provided clues to the diagnosis of this type of lesser sac hernia.
