Abstract
Background
Incisional hernias are one of the most common long-term complications associated with open abdominal surgery. The aim of this review and meta-analysis was to systematically assess laparoscopic versus open abdominal surgery as a general surgical strategy in all available indications in terms of incisional hernia occurrence.
Methods
A systematic literature search was performed to identify randomized controlled trials comparing incisional hernia rates after laparoscopic versus open abdominal surgery in all indications. Random effects meta-analyses were calculated and presented as risk differences (RD) with their corresponding 95 % confidence intervals (CI).
Results
24 trials (3490 patients) were included. Incisional hernias were significantly reduced in the laparoscopic group (RD −0.06, 95 % CI [−0.09, −0.03], p = 0.0002, I
2 = 75). The advantage of the laparoscopic procedure persisted in the subgroup of total-laparoscopic interventions (RD −0.14, 95 % CI [−0.22, −0.06], p = 0.001, I
2 = 87 %), whereas laparoscopically assisted procedures did not show a significant reduction of incisional hernias compared to open surgery (RD −0.01, 95 % CI [−0.03, 0.01], p = 0.31, I
2 = 35 %). Wound infections were significantly reduced in the laparoscopic group (RD −0.06, 95 % CI [−0.09, −0.03], p < 0.0001, I
2 = 35 %); overall postoperative morbidity was comparable in both groups (RD −0.06, 95 % CI [−0.13, 0.00], p = 0.06; I
2 = 64 %). Open abdominal surgery showed a significantly longer hospital stay compared to laparoscopy (RD −1.92, 95 % CI [−2.67, −1.17], p < 0.00001, I
2 = 87 %). At short-term follow-up, quality of life was in favor of laparoscopy.
Conclusions
Incisional hernias are less frequent using the total-laparoscopic approach instead of open abdominal surgery. Whenever possible, the less traumatic access should be chosen.
