In patients with colorectal cancer, laparoscopic resection reduced total hospital stay by a median of 2 days, compared with open surgery, researchers reported online May 5 in the Journal of Clinical Oncology.
However, laparoscopy did not significantly improve physical fatigue at 1 month, compared with open surgery, and it did not affect other secondary clinical outcomes, said Prof. Robin Kennedy of St. Mark’s Hospital, Harrow, England, and his associates.
The researchers conducted a multicenter, randomized trial of 204 patients with colorectal cancer, of whom 103 underwent laparoscopic resection and 101 had open surgery within a standardized enhanced recovery program (J. Clin. Oncol. 2014 May 5 [doi: 10.1200/JCO.2013.54.3694]).
Median total hospital stay was significantly shorter in the laparoscopy group (5 days; interquartile range, 4-9 days) vs. the open surgery group (7 days; IQR, 5-11 days; P = .033), the investigators reported. However, 1-month physical fatigue scores on the Multidimensional Fatigue Inventory 20 were similar between the two groups (mean for laparoscopy patients, 12.28; 95% confidence interval, 11.37-13.19; mean for open surgery patients, 12.05; 95% CI, 11.14-12.96; adjusted mean difference, –0.23; 95% CI, –1.52-1.07), the researchers reported. Other outcomes also were similar, including quality of the specimens based on central pathologic review, the researchers said.
The findings contradicted those of prior studies in which shorter duration of hospital stay correlated with less "pain, ileus, and other complications, leading to earlier mobilization, feeding, and recovery," the researchers noted. They recommended more studies to determine whether the similarities between other outcomes were due to a lack of power or truly indicated comparable short-term recoveries.
