Postoperative results of left upper abdominal evisceration for advanced gastric cancer

In spite of the improvement of surgical techniques, the prognosis of patients with advanced gastric cancer still remains poor. With the aim of achieving en bloc resection of primary tumor, peritoneal dissemination on the greater omentum and lymph node metastasis, left upper abdominal evisceration (LUAE) was performed for 75 patients. In this report, we investigated the prognostic difference between the LUAE group and standard gastrectomy (total gastrectomy + pancreatosplenectomy).

In the LUAE group, total gastrectomy was performed with the en bloc resection of the transverse colon, pancreas body and tail, spleen and left adrenal gland. In addition, omental bursa, covering retroperitoneum and pancreas body and tail was resected in combination with greater omentum, transverse mesocolon, and lesser omentum.

There were 3 (4.1%) postoperative death in the LUAE group, and 2 (1.7%) in the control group. However, there was no statistical difference in the incidence of postoperative complications between these 2 groups. The overall 5-year survival rates of the LUAE and control groups were 33% and 39%, respectively. There was no statistical survival difference between these 2 groups. Survival difference between the LUAE and control group was not found in terms of tumor location, wall invasion, lymph node status, peritoneal dissemination, and macroscopic type.

From these results, LUAE cannot improve the survival of patients with advanced gastric cancer. Consequently, LUAE should be indicated for T4 tumors, which directly invade into the transverse colon.
