Comparison of laparoscopy-assisted and totally laparoscopic Billroth-II distal gastrectomy for gastric cancer.

PURPOSE

In laparoscopic distal gastrectomy for gastric cancer, most surgeons prefer extra-corporeal anastomosis because of technical challenges and unfamiliarity with intra-corporeal anastomosis. Herein, we report the feasibility and safety of intra-corporeal Billroth-II anastomosis in gastric cancer.

METHODS

From April 2004 to March 2011, 130 underwent totally laparoscopic distal gastrectomy with intra-corporeal Billroth-II reconstruction, and 269 patients underwent laparoscopy-assisted distal gastrectomy with extra-corporeal Billroth-II reconstruction. Surgical efficacies and outcomes between two groups were compared.

RESULTS

There were no differences in demographics and clinicopathological characteristics. The mean operation and reconstruction times of totally laparoscopic distal gastrectomy were statistically shorter than laparoscopy-assisted distal gastrectomy (P = 0.019; P < 0.001). Anastomosis-related complications were observed in 11 (8.5%) totally laparoscopic distal gastrectomy and 21 (7.8%) laparoscopy-assisted distal gastrectomy patients, and the incidence of these events was not significantly different. Post-operative hospital stays for totally laparoscopic distal gastrectomy were shorter than laparoscopy-assisted distal gastrectomy patients (8.3 ± 3.2 days vs. 9.9 ± 5.3 days, respectively; P = 0.016), and the number of times parenteral analgesic administration was required in laparoscopy-assisted distal gastrectomy patients was more frequent after surgery.

CONCLUSION

Intra-corporeal Billroth-II anastomosis is a feasible procedure and can be safely performed with the proper experience for laparoscopic distal gastrectomy. This method may be less time consuming and may produce a more cosmetic result.
