Totally laparoscopic complete bursectomy and D2 lymphadenectomy in radical total gastrectomy: an outside bursa omentalis approach

Abstract

Background: Bursectomy is regarded as a standard surgical procedure during gastrectomy for serosa-positive gastric cancer in Japanese gastric cancer treatment guidelines (Japanese Gastric Cancer Association in Gastric Cancer 14:113–123, 2011). As a consequence, bursectomy is widely performed in open gastrectomy. However, laparoscopic gastrectomy with bursectomy is rare. Based on our previous experience of laparoscopic bursectomy in distal gastrectomy (Zou et al. in Oncol Lett 10:99–102, 2015), herein, we described the technique of totally laparoscopic radical total gastrectomy with complete bursectomy using an outside bursa omentalis approach. Methods: Firstly, the transverse mesocolon and distal gastric membrane were separated from right to left, and the right gastroepiploica vessels were ligated at root with No. 6 lymph nodes (LNs) dissection followed by the pancreas membrane dissection from pancreas head to pancreas tail. Secondly, the anterior plane of transverse mesocolon was dissected from left to right starting from the lower pole of spleen, and the membrane of pancreas tail was separated to combine the pancreas anterior plane with No. 4s, 10, 11d and 2 LNs dissection. Thirdly, the lesser omental was dissected from right to left with No. 5 and 12a LNs dissection, and the duodenum was transected. Then, the No. 7, 8, 9 and 11p LNs were dissected followed by No. 1 LNs dissection. Finally, a Roux-en-Y esophagojejunostomy was carried out intracorporeally with a linear cutter. Results: Thirty-two patients with advanced proximal gastric cancer underwent laparoscopic total gastrectomy with complete bursectomy using an approach outside bursa omentalis. One bowel obstruction and one pulmonary infection were recorded and cured with conservative measure. The mean operative time was 253.3 ± 31.3 min with a mean blood loss of 90.5 ± 23.1 ml. The mean length of stay was 10.6 ± 2.6 days. Conclusion: Laparoscopic radical total gastrectomy with complete bursectomy using an outside bursa omentalis approach is feasible and safe in experienced hands with favorable short outcome. Further studies were needed for its advanced application.
