Laparoscopy in the management of scirrhous gastric cancer.

BACKGROUND

Scirrhous gastric cancer frequently shows extensive tumor spread, and gastrectomy for cure of the disease is not possible in the presence of peritoneal dissemination, which is often overlooked by conventional computed tomography. The aim of this study was to evaluate our experience of 16 patients who underwent laparoscopy in the management of scirrhous gastric cancer, and to examine whether peritoneal dissemination could be diagnosed accurately by laparoscopy.

METHODS

All patients had nonobstructed, nonbleeding scirrhous gastric cancer and had no evidence of metastatic disease by ultrasonography and computed tomography. Laparoscopy was performed under general anesthesia with CO(2) pneumoperitoneum. A Hasson trocar and two manipulating forceps were inserted, and the surfaces of the peritoneum, omentum, stomach, spleen, pancreas, liver, and diaphragm were examined.

RESULTS

The mean time for laparoscopy was 20 min. Peritoneal dissemination was disclosed in 4 patients (25%), and systemic and intraperitoneal chemotherapy was done without laparotomy. In 12 patients, subsequent gastrectomy with a curative intent was successfully performed. Pathology revealed that the tumor diffusely invaded the whole thickness of the gastric wall; the mean size of resected tumors was 12 cm, and the mean number of positive nodes was 17. Nine patients died of the disease with a mean survival period of 10 months, and 7 patients were alive without recurrence during a mean follow-up period of 11 months.

CONCLUSIONS

Laparoscopy is useful for the evaluation of peritoneal spreads of advanced gastric cancer, can avoid unnecessary laparotomy because of peritoneal dissemination, and is important for the choice of treatments in patients with scirrhous gastric cancer.
