[Emergencies in the surgery of colonic neoplasms. A review of the literature and the authors' cases].

The paper reports the personal experience of the 2nd Division of General Surgery of the Martini Hospital in Turin and compares it to the results of the most recently published studies. Of 123 patients who underwent emergency surgery, 101 were suffering from tumors of the colon complicated by intestinal occlusion and 22 by perforation. Only right hemicolectomy was performed in cases of perforation or resection with ileostomy and colic mucous fistula was used for neoplasms located in the right colon; Hartmann's operation or dual ostomy was performed in the event of neoplasms in the left colon. Surgical treatment of occlusive tumors of the left colon is still the subject of continued debate. The elective surgical technique is an amblée resection using colo-colic anastomosis with a protective ostomy. This is followed by Hartmann's operation, whereas decompressive colostomy should only be used in patients who are admitted to hospital in generally precarious conditions.
