Purpose: A laparoscopy-assisted gastrectomy with lymph node dissection for gastric cancer is considered technically more complicated than the open method. To evaluate the short-term surgical validity, the surgical outcome of the laparoscopy-assisted distal gastrectomy (LADG) with extraperigastric lymph node dissection was compared with that of the conventional open distal gastrectomy (CODG) in patients with early gastric cancer.
Methods: One hundred and forty-seven patients with early gastric cancer received a radical distal gastrectomy during 2002 and 2003, where a LADG was performed on 71 patients. The clinicopathological characteristics, postoperative outcomes and courses, and the postoperative morbidities and mortalities were compared between the two groups. Data were retrieved from the stomach cancer database at Dong-A University Medical center.
Results: Baseline characteristics, including gender, age, body mass index (BMI), American Society of Anesthesiology (ASA) class, tumor size, T stage, and lymph node metastasis, were similar between the two groups. No significant differences were found between these groups in terms of the number of retrieved lymph nodes with respect to D1+ (D1+no. 7) and D1+β (D1+no. 7, 8a, and 9) lymphadenectomies. In the LADG group, the wound size was smaller (P＜0.0001), but the operation time was longer (P=0.0001) than in the CODG group. The perioperative recovery was faster in the LADG than in the CODG group, as reflected by the shorter hospital stay (P=0.0176) and less additional analgesics (P=0.0370). The serum albumin level in the LADG was higher (P=0.0002) on day 7 than that in the CODG group, and the leukocyte count in the LADG lower (P=0.0445) on day 1 than that in the CODG gruop. There were no significant differences in the postoperative morbidities and mortalities between the two groups.
Conclusions: Our data confirmed that a LADG with an extraperigastric (no. 7, 8, and 9) lymph node dissection was a feasible and acceptable surgical technique for early gastric cancer. From a surgical point of view, a LADG with an extraperigastric lymph node dissection is suggested to be a preferred surgical option for patients with early gastric cancer. Its oncological validity awaits larger and prospective multicenterd trials.
