Sumario:AIMS: This study aims to evaluate comparative outcomes following midline versus off-midline specimen extractions following laparoscopic left-sided colorectal resections. METHODS: A systematic search of electronic information sources was conducted. Studies comparing ‘midline’ versus ‘off midline’ specimen extraction following laparoscopic left-sided colorectal resections performed for malignancies were included. The rate of incisional hernia formation, surgical site infection (SSI), total operative time and blood loss, anastomotic leak (AL) and length of hospital stay (LOS) was the evaluated outcome parameters. RESULTS: Five comparative observational studies reporting a total of 1187 patients comparing midline (n = 701) and off-midline (n = 486) approaches for specimen extraction were identified. Specimen extraction performed through an off-midline incision was not associated with a significantly reduced rate of SSI (odds ratio [OR]: 0.71; P = 0.68), the occurrence of AL (OR: 0.76; P = 0.66) and future development of incisional hernias (OR: 0.65; P = 0.64) compared to the conventional midline approach. No statistically significant difference was observed in total operative time (mean difference [MD]: 0.13; P = 0.99), intraoperative blood loss (MD: 2.31; P = 0.91) and LOS (MD: 0.78; P = 0.18) between the two groups. CONCLUSIONS: Off-midline specimen extraction following minimally invasive left-sided colorectal cancer surgery is associated with similar rates of SSI and incisional hernia formation compared to the vertical midline incision. Furthermore, there were no statistically significant differences observed between the two groups for evaluated outcomes such as total operative time, intra-operative blood loss, AL rate and LOS. As such, we did not find any advantage of one approach over the other. Future high-quality well-designed trials are required to make robust conclusions.
