摘要

Background

Elective laparotomies account for a larger fraction of laparotomy procedures performed worldwide. Although surgical techniques continue to advance, the incidence of incisional hernia (IH) and other post-operative complications remain challenging to surgeons. This study aimed to evaluate the significance of using prophylactic mesh reinforcement during elective laparotomy.

Methods

A comprehensive search was conducted in PubMed, Scopus, and Web of Science to identify studies that included adults undergoing elective abdominal surgery and compared prophylactic mesh reinforcement of the abdominal wall using any type of mesh in any anatomical position to standard fascial closure with sutures alone, without mesh. The analysis aimed to assess the impact of mesh reinforcement on the incidence of IH at all possible timepoints, in addition to secondary outcomes based on mesh technique, such as wound infections, dehiscence, seroma, re-operation for IH, and prolonged hospital stay. Data analysis was performed using the R programming language.

Results

Fifteen RCTs, including 2,233 patients with follow-up durations ranging from 1.5 to 5 years, were analyzed. Prophylactic mesh reinforcement significantly reduced the incidence of IH following elective gastrointestinal surgeries at 12 months (risk ratio [RR] = 0.35, 95% confidence interval [CI] [0.14; 0.86], p = 0.02), 24 months (RR = 0.28, 95% CI [0.11; 0.68], p < 0.01), 36 months (RR = 0.62, 95% CI [0.36; 1.06], p = 0.08), and 48 months (RR = 0.35, 95% CI [0.11; 1.17], p = 0.09). Similarly, mesh significantly reduced IH rates following open abdominal aortic aneurysm repair at 12 months (RR = 0.13, 95% CI [0.04; 0.41], p < 0.01), 24 months (RR = 0.31, 95% CI [0.21; 0.45], p < 0.01), and 36 months (RR = 0.23, 95% CI [0.10; 0.54], p < 0.01).

Conclusions

Prophylactic mesh reinforcement during elective abdominal laparotomy significantly reduced the incidence of IH and the need for reoperation. However, it is associated with an increased risk of seroma formation and, to a lesser extent, wound infection, particularly with the Sublay technique.
