Abstract
To compare the short-term results after left-sided laparoscopic colectomy with transanal and transabdominal specimen extraction. We selected 998 appropriate manuscripts and subsequently excluded 995 ones due to exclusion criteria. Thus, the meta-analysis was based on 3 randomized trials in accordance with PRISMA recommendations. A total of 353 patients were enrolled in meta-analysis including 169 resections with transanal specimen extraction and 184 surgeries with transabdominal extraction. Overall risk of postoperative complications (OR=0.60; 95% CI 0.31-1.14; p=0.12) including anastomotic leakage (OR=1.83; 95% CI 0.43-7.89; p=0.42) was similar in both groups. At the same time, severity of pain syndrome (mean difference = -2.35; 95% CI -2.51-2.19), time to the first flatus discharge (mean difference = -0.92; 95% CI -0.99-0.85) and postoperative hospital stay (mean difference = -1.5; 95% CI -2.03-0.98) were significantly lower in the group of transanal extraction (p<0.00001). Transanal specimen extraction in left-sided laparoscopic colectomy does not increase overall risk of postoperative complications. In addition, the NOSE technique has some advantages in short-term results compared to procedures with transabdominal specimen extraction.
