Open versus laparoscopic right hemicolectomy in the elderly population.

Area of Science:

• Colorectal Surgery
• Minimally Invasive Surgery
• Geriatric Surgery

Background:

• Elective right hemicolectomy (RH) is a common procedure for elderly patients.
• Laparoscopic surgery offers potential benefits, but its outcomes in older populations require specific evaluation.

Purpose of the Study:

• To compare short-term outcomes of elective laparoscopic versus open right hemicolectomy (RH) in patients aged 70 and above.
• To assess differences in operative duration, length of hospital stay, morbidity, and mortality.

Main Methods:

• A prospective database analysis of 206 patients (≥70 years) undergoing elective RH between 2006 and 2011.
• Comparison of open (n=125) versus laparoscopic (n=81) RH, with routine extracorporeal anastomosis in the laparoscopic group.
• Primary endpoints: morbidity and mortality. Secondary endpoints: operative time, hospital stay, and discharge destination.

Main Results:

• Laparoscopic RH had a significantly longer mean operative time (197 ± 53 min) compared to open RH (139 ± 36 min; P=0.001).
• Mean hospital stay was similar: 11.2 ± 7.8 days (open) vs. 9.6 ± 10.7 days (laparoscopic; P=0.28).
• Post-operative morbidity was 27% (open) vs. 38% (laparoscopic; P=0.12), and in-hospital mortality was 0.8% (open) vs. 1% (laparoscopic).

Conclusions:

• Laparoscopic RH in the elderly was associated with increased operative time compared to open RH.
• This study did not demonstrate reduced post-operative morbidity or shorter hospital stay with laparoscopic RH in this elderly cohort.
