D2 subtotal gastrectomy performed by MIS is reproducible and safe. The long-term outcomes and 5-year survival are acceptable. Extended lymphadenectomy was carried out for both EGC and AGC so as to ensure adequate nodal clearance and compensate preoperative underestimation.

Short-term results with laparoscopic gastrectomy were better than with open surgery in this study. Oncologic radicality was a major concern, but in the authors' experience the extent of lymphadenectomy was the same as in open surgery. This study suggests that laparoscopic gastrectomy in malignancies is a reliable tool and oncologic requirements can be warranted.

LL of the IMA in LAR + TME results in better GU function preservation without affecting initial oncological outcomes. HL does not seem to increase the anastomotic leak rate.

Laparoscopic surgery for sigmoid diverticulitis in experienced hands can be a safe and effective gold standard procedure also for patients with fistula or purulent peritonitis.
