Background: A debate is still surrounding the use of laparoscopic surgery for advanced gastric cancer (AGC) related to doubts about the requirements to satisfy oncologic criteria. The aim of this study is to analyze the oncological results, the intraoperative complications, and the short-and medium-Term morbidity and mortality in patients with AGC who underwent subtotal laparoscopic gastrectomy (SLG) or total laparoscopic gastrectomy (TLG) with extended lymphadenectomy. Materials and Methods: We reviewed medical records of patients who underwent radical gastrectomy for AGC started laparoscopically with the intent of curative surgery, between July 2007 and October 2015. We recruited 74 patients and studied demographics, American Society of Anesthesiologists (ASA) score, pTNM stage, histologic pattern of the tumor, duration of surgery, conversion rate, estimated blood loss, number of resected lymph nodes, type of gastrointestinal reconstruction, postoperative complication, mortality rate, length of stay, time to canalization and resumption of food intake, and overall and disease-free survival rate. Results: We performed 74 interventions, with a conversion rate of 14.9% (11/74). Sixty-Three were performed totally as laparoscopic: 43 (68.25%) SLGs and 20 (31.75%) TLGs, all with an extended lymphadenectomy (D2 or more). Operative time was 150 ± 34 minutes (range 75-225 minutes), the mean number of resected lymph nodes 21.4 ± 6.2, global morbidity rate 25.39%, rate of reoperation 9.52%, and perioperative mortality at 30 days 0%. We performed an average follow-up of 48.7 months (range 18-60), and we observed 5-year overall and disease-free survival, respectively, of 48.6% and 42.7%. Conclusions: LG with extended lymphadenectomy for AGC is a feasible procedure with good results in terms of postoperative course, complications, and mortality. Thanks to the use of extremely precise and safe technologies the extended lymphadenectomy can be performed laparoscopically. The laparoscopic approach, when performed by experienced surgeons, ensures a correct oncological treatment in combination with the benefits of the laparoscopic technique.

The aim of this study is to analyze the oncological results, the intraoperative complications, and the short-and medium-Term morbidity and mortality in patients with AGC who underwent subtotal laparoscopic gastrectomy (SLG) or total laparoscopic gastrectomy (TLG) with extended lymphadenectomy. Materials and Methods: We reviewed medical records of patients who underwent radical gastrectomy for AGC started laparoscopically with the intent of curative surgery, between July 2007 and October 2015.
