Introduction: The debate is still open about laparoscopic treatment of gastric cancer. The aim of this retrospective study is to analyze our short-, medium-, and long-term surgical and oncological results in laparoscopic treatment of gastric cancer with D2 lymphadenectomy and omentum preservation. Materials and Methods: From January 2010 to June 2018, after >150 surgical procedures for gastric cancer performed by minimally invasive approach, we performed 100 laparoscopic subtotal gastrectomies and 38 total gastrectomies, both for early gastric cancer (EGC) and advanced gastric cancer (AGC). We always made a D2 lymphadenectomy or higher. As often as possible, we performed omentum-preserving technique. Primary outcomes analyzed included incidence of medical and surgical complications. Secondary outcomes analyzed were survival probability and incidence of relapse. Every patient read and signed informed consent before surgery. Results: Mean operative time: 2.4 ± 0.7 hours (range 1.2-4.7 hours). Rate of conversions: 14.5% (20/138); intraoperative complications: 1.4% (2/138) and positive resection margins: 6.5% (9/138). Overall incidence of duodenal fistula: 3.6% (5/138). Rate of reoperation was 7.3% (10/138). Postoperative complications according to Clavien-Dindo classification: I 3.6% (5/138); II 13.0% (18/138); III 5.8% (8/138); III B 0.7% (1/138); V 1.4% (2/138). Overall survival with 60 months follow-up was 58%. Overall 60 months incidence of relapse was 44%. Patients with omentum preservation had a lower incidence of relapse than patients with omentectomy (40% versus 57% P =.002). Conclusions: Laparoscopic treatment of gastric cancer with D2 lymphadenectomy and omentum preservation is safe and feasible, both for EGC and for AGC. Although this study has limitations, omentum-preserving technique was associated with a statistically lower recurrence rate.

Purpose: Although the modified Sugarbaker technique gives good results for the treatment of parastomal hernia (PH), there are other valid options for the treatment of this frequent complication. In our practice, the laparoscopic keyhole (KH) technique, with some specific modifications, can give similar results. Materials and Methods: We collected data on all the patients with symptomatic PHs who underwent surgical repair between January 2002 and December 2017 in our surgical department. The primary endpoint was to evaluate the recurrence rate after at least 1 year, determined on the basis of physical examination during follow-up and on postprocedure radiological results. Results: Ninety patients were treated with the KH technique. The stomas that were treated were 83 end colostomies and 7 ileal ureterostomies. Eighty-eight patients were treated with polyester mesh (Parietex™, Medtronic, Ireland) and 2 with a composite mesh (Physiomesh™, Ethicon). Patients had median follow-up period of 1 year. Seroma occurred in 4 patients, who were treated conservatively by clinical monitoring. Four patients had a recurrence: 1 occurred on the seventh postoperative day, due to a technical error; 1 after 6 months, due to the partial shrinkage of the mesh into the defect; the third after 1 year, but it occurred at the beginning of our experience, and the last recurrence was after 3 years in a patient who gained 15 kg after the procedure. Conclusions: If a few precautionary steps are added to the original technique, laparoscopic KH repair is feasible and safe, giving good results in terms of complications and recurrence rates.

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.
