Several studies have addressed the issue of the feasibility of laparoscopic colorectal surgery in elderly patients, usually by choosing an arbitrary cut-off age limit, and retrospectively evaluating patient outcomes. The aim of this study was to assess the effects of age on the outcome of laparoscopic colorectal surgery for cancer in a single department, by comparing younger and older patients, matched by ASA score and type of operation.The perioperative outcome of patients ≥75 years old who underwent laparoscopic colorectal surgery for cancer between June 2005 and January 2009 were compared with findings in younger patients, matched by ASA score and type of operation.The study included 100 patients, fifty75 years old (Group A) and fifty ≥75 (Group B) years old. There were 18 right hemicolectomies, 16 left hemicolectomies, 4 anterior resections, 9 low anterior resections, 2 Miles' operations and 1 segmental resection in each group. We observed a significantly higher overall morbidity rate among elderly patients than among younger patients (24 vs. 8%).Short-term results after laparoscopic colorectal surgery for cancer in patients ≥75 years old reveal that they have higher postoperative risk compared to their younger counterparts, even when matched by ASA score and type of operation. It suggests that although advanced age, per se, is not a contraindication, it is a risk for patients who undergo laparoscopic colorectal surgery for cancer. This surgery in elderly patients should be performed by experienced surgeons in specialized centers to keep postoperative risk to a minimum.

The use of laparoscopy for colorectal cancer resection is still controversial.We prospectively analyzed the outcome of minimally invasive resection for colorectal cancer, performed at our institution from 1998, when laparoscopic surgery became the treatment of choice for colorectal cancer, until 2004. All patients undergoing elective resection were assessed in terms of perioperative results (duration of surgery, number of lymph nodes removed, length of specimen, rate of conversion, complications) and survival. Patients were assessed yearly with follow-up visits and telephone interviews.In the study period, 302 patients (mean age 66.1 years; range, 32-93 years) underwent 114 left hemicolectomies, 108 low anterior resections, 61 right hemicolectomies, 12 Miles procedures, 4 subtotal colectomies, and 3 transverse colon resections. Surgery took an average of 226 minutes (SD=71 min). The number of lymph nodes removed was 14+/-8. The conversion rate was 10%; most of the conversions were due to locally advanced cancer (15 cases) and bowel distension (7 cases). Fifteen anastomotic leaks were observed (5%). Twenty patients needed reoperation and two died: one of septic shock due to an anastomotic leak; the other of electrolyte imbalance and dehydration after peritonitis due to a bowel loop injury. Follow-up was available for 91% of patients. Cancer-related survival curves showed a 90% survival for stage II, 85% for stage III, and 10% for stage IV disease, 30 months after surgery.Minimally invasive laparoscopic resection for colorectal cancer enables an oncologically adequate resection with complication and survival rates that are no worse than are to be expected after traditional open surgery. Locally advanced tumor and bowel distension are the most frequent reasons for conversion to open surgery.
