Short-term clinical outcomes of laparoscopic gastrectomy for remnant gastric cancer: A single-institution experience and systematic review of the literature.

Aim: Application of laparoscopic approaches for the treatment of remnant gastric cancers (RGC) is still controversial. Therefore, in the present study, the safety and effectiveness of laparoscopic gastrectomy (LG) for RGC was investigated.
Methods: A total of 27 patients who underwent gastrectomy for RGC from June 2008 to September 2017 were enrolled in this study. A comprehensive review of the literature on LG for RGC published before December 2017 using the PubMed database was carried out.
Results: Laparoscopic gastrectomy was carried out in seven patients, and open gastrectomy (OG) was done in the remaining 20 patients. LG was associated with significantly less intraoperative blood loss (70 ± 71 vs. 1066 ± 1428 g; P  < 0.001), significantly more retrieved lymph nodes (22 ± 13 vs. 12 ± 9; P  = 0.03), a relatively lower postoperative complication rate, and a relatively shorter postoperative hospital stay than OG. A comprehensive review of the literature showed that LG for RGC was more likely to correlate with longer operative time, less blood loss, lower postoperative complication rate, shorter postoperative hospital stay, and more retrieved lymph nodes than OG.
Conclusion: The clinical outcome of our patients with RGC and the literature indicated that a laparoscopic approach contributed to faster recovery after surgery than an open approach without sacrificing its radicality and was a safe and secure treatment option for RGC.
