Background:
The aim of the present study was to compare the clinical outcomes of emergency laparoscopic-assisted versus open right hemicolectomy for obstructing right-sided colonic carcinoma.
Methods:
Between July 2003 and July 2006, 43 consecutive patients with obstructing right-sided colonic carcinoma underwent emergency right hemicolectomy at our institution, 14 with the laparoscopic-assisted approach and 29 with the open approach. Clinical data were retrospectively recorded and compared between the two groups.
Results:
There were no significant differences between the two groups with respect to age, gender, co-morbidities, duration of obstructing symptoms, tumor length, and tumor staging. The laparoscopic-assisted group had longer operative time than the open group (187.5 min versus 145 min; p=0.034) but less blood loss (20 ml versus 100 ml; p=0.020). The median time to full ambulation was significantly shorter in the laparoscopic-assisted group (4 days versus 6 days; p=0.016), but the time to return of gastrointestinal function and the duration of hospital stay were similar between the two groups. More patients in the open group developed postoperative complications (55.2% versus 28.6%), but the difference was not statistically significant.
Conclusions:
Emergency laparoscopic-assisted right hemicolectomy for obstructing right-sided colonic carcinoma is feasible and safe. In comparison with the open approach, the laparoscopic-assisted procedure is associated with less blood loss, earlier ambulation, and possibly lower morbidity rate.
