Abstract
BACKGROUND: Cardiac and pulmonary complications account for a large part of postoperative mortality, especially in the growing number of elderly patients. This review studies the effect of laparoscopic surgery for colorectal cancer on short term non-surgical morbidity. METHODS: A literature search was conducted to identify randomised trials on laparoscopic compared to open surgery for colorectal cancer with reported cardiac or pulmonary complications. RESULTS: The search retrieved 3302 articles; 18 studies were included with a total of 6153 patients. Reported median or mean age varied from 56 years to 72 years. The percentage of included patients with ASA-scores ≥ 3 ranged from 7% to 38%. Morbidity was poorly defined. Overall reported incidence of postoperative cardiac complications was low for both laparoscopic and open colorectal resection (median 2%). There was a trend towards fewer cardiac complications following laparoscopic surgery (OR 0.66, 95% CI 0.41-1.06, p = 0.08), and this effect was most marked for laparoscopic colectomy (OR 0.28, 95% CI 0.11-0.71, p = 0.007). Incidence of pulmonary complications ranged from 0 to 11% and no benefit was found for laparoscopic surgery, although a possible trend was seen in favour of laparoscopic colectomy (OR 0.78, 95% CI 0.53-1.13, p = 0.19). Overall morbidity rates varied from 11% to 69% with a median of 33%. CONCLUSION: Although morbidity was poorly defined, for laparoscopic colectomies, significantly less cardiac complications occurred compared with open surgery and a trend towards less pulmonary complications was observed. Subgroup analysis from two RCTs suggests that elderly patients benefit most from a laparoscopic approach based on overall morbidity rates.
