Abdominal incisions: techniques and postoperative complications.
OBJECTIVE
The choice of incision for laparotomy depends on the area that needs to be exposed, the elective or emergency nature of the operation and personal preference. Type of incision may however have its influence on the occurrence of postoperative wound complications. Techniques and features of various incisions are discussed, as well as the incidence of their postoperative complications.


METHODS
A medline search was conducted identifying prospective randomised trials, as well as retrospective studies with sufficient follow-up, comparing midline, paramedian, transverse and oblique incisions.


RESULTS
Significant differences in wound infection and wound dehiscence rates were not reported. Transverse, oblique and paramedian incisions caused significantly less incisional hernias than midline incisions. However, trials comparing transverse and midline incisions for larger laparotomies did not show significant differences. All four trials comparing lateral paramedian with midline incisions reported incisional hernia rates of 0% after the lateral paramedian incision. Differences with the midline incision were significant.


CONCLUSIONS
Transverse or oblique incisions should be preferred for small unilateral operations. The paramedian incision should be used for major elective laparotomies. The use of the midline incision should be restricted to operations in which unlimited access to the abdominal cavity is useful or necessary.
