Staged laparoscopic management of locally advanced gastric cancer with outlet obstruction.

BACKGROUND The prognosis of patients with locally advanced gastric cancer with outlet obstruction is poor. Gastrectomy with curative intent is often initially impossible or difficult. OBJECTIVE We report our experience of curative distal gastrectomy after laparoscopic gastrojejunostomy and fluorouracil, leucovorin, oxaliplatin, and docetaxel (FLOT) chemotherapy to examine the feasibility and safety of this modified strategy for locally advanced gastric cancer with outlet obstruction, initially deemed unresectable. METHODS Between October 2017 and June 2019, 15 patients diagnosed with locally advanced gastric cancer with outlet obstruction sequentially underwent gastrojejunostomy, received four cycles of FLOT chemotherapy, and underwent laparoscopic distal gastrectomy with curative intent (R0 resection + D2 lymphadenectomy). Clinical data were retrospectively collected and analyzed. RESULTS R0 resection was possible in 12/15 patients, laparoscopically in 11, and one conversion to laparotomy was necessary. There was no perioperative mortality in the 12 patients. Pathologic evaluation of the resected specimens revealed that complete tumor grade regression 1a (TRG1a), TRG1b, TRG2, and TRG3 occurred in 3, 2, 4, and 3 patients, respectively. CONCLUSION This case series showed that curative surgical resection was feasible as a staged approach for patients with locally advanced gastric cancer with outlet obstruction, after initial staged gastrojejunostomy and chemotherapy.
