Hernia incidence following single-site vs standard laparoscopic colorectal surgery.
AIM: Compared with standard laparoscopic (SDL) approaches, less is known about the incidence of hernias after single-site laparoscopic (SSL) colorectal surgery. This study hypothesized that SSL colorectal surgery was associated with an increased risk of hernia development.
METHOD: Institutional retrospective chart review (September 2008-June 2013) identified 276 evaluable patients who underwent laparoscopic colorectal procedures. The following data were collected: demographic data, risk factors for the development of a hernia, operative details and postoperative course including the development of a hernia. Patients were stratified by laparoscopic technique to compare the characteristics of those undergoing SDL and SSL. Patients were subsequently stratified by the presence or absence of a hernia to identify associated factors.
RESULTS: One hundred and nineteen patients (43.1%) underwent SDL and 157 patients (56.9%) underwent SSL surgery. The development of an incisional hernia was observed in 7.6% (9/119) of SDL patients compared with 17.0% (18/106) of SSL patients (P = 0.03) over a median 18-month follow-up. Similar proportions of patients developed parastomal hernias in both groups [SDL 16.7% (10/60) vs SSL 15.9% (13/80)]. Hernias were diagnosed at a median of 8.1 (SDL) and 6.5 (SSL) months following the index operation and were less likely to be incarcerated in the SSL group [SDL 38.9% (7/18) vs SSL 6.5% (2/31), P = 0.01].
CONCLUSION: SSL colorectal surgery is associated with an increase in the incidence of incisional hernias but not parastomal hernias. Site of specimen extraction in SSL may contribute to the development of an incisional hernia.
