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.

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.

No evidence of relevant differences in terms of functional and safety outcomes between the two laparoscopic procedures. TLC determines less abdominal manipulation and shorter incision length, but clear advantages must be still demonstrated. Larger series are necessary to test the superiority of totally laparoscopic procedures for right colectomy.
