Efficacy of hand-assisted laparoscopic surgery (HALS) in older adult patients (≥80 years) with primary colorectal cancer

BACKGROUND: From 2004 to 2014, 821 colorectal cancer primary resections were conducted at our institution. Of these, 102 patients (12.4%) were older adults over 80 years old. underwent either the conventional laparotomy group (72 patients) or the hand-assisted laparoscopic surgery (HALS) group (30 patients). METHODS: Data were extracted for 102 patients over 80 years old who underwent primary resection for colorectal cancer and were divided into two groups: conventional laparotomy (CL) (n=72) and hand-assisted laparoscopy (n=30). Pre-operative characteristics and outcomes were compared. RESULTS: Baseline characteristics were similar between groups, except for age: CL group median 83.5 years old (range, 80–92 years old) and hand-assisted laparoscopy (HALS) group median 81.5 years old (range, 80–88 years old) (P=0.027). Pre-operative cardiac and lung function risk, performance status, and pathological classification stage (pStage) were almost similar between groups (P=0.668, P=0.176, P>0.999, P=0.217). No significant differences were found for operation time. The HALS group resulted in less blood loss (median 204 mL in the CL group and median 68 mL in the HALS group, P=0.003), shorter postoperative hospital stay (median was 18 days in the CL group and median was 12 days in the HALS group, P
