Abstract
Background: Since 1991, laparoscopy-assisted Billroth I gastrectomy has been used for patients with early gastric cancer. The aim of this study was to clarify the outcome of 40 patients who underwent this operation and to examine the indications based on a retrospective histological study of 248 resected cases of early gastric cancer. Methods: Operating time, blood loss, length of skin incision, and postoperative hospital stay and complications were examined using the operation records and medical charts. The presence or absence of lymph node metastasis, tumour size, site, gross type, histological type, depth of invasion, presence or absence of ulceration, and status of lymph node metastasis were investigated in 248 early gastric cancers. Results: The mean operating time was 3 h and 48 min and the mean length of skin incision was 5·8 cm. Although one patient who had suffered from chronic bronchitis developed pneumonia and wound dehiscence, no other patients had a postoperative complication. The mean hospital stay after operation was 16 days and all patients were alive without recurrence at a median follow-up of 21 months. The incidence of lymph node metastasis in early gastric cancer was 2 per cent (three of 130) in mucosal cancers and 14 per cent (17 of 118) in submucosal cancers. These lesions could have been completely resected by laparoscopy-assisted gastrectomy. Conclusion: All 40 patients were treated successfully by laparoscopy-assisted Billroth I gastrectomy without significant complications and with no recurrences to date. Pathological study of conventionally resected stomach and lymph nodes confirmed that laparoscopy-assisted Billroth I gastrectomy would be a safe and useful operation for most early gastric cancers.
