Abstract
Background
Despite increasing data regarding clinical outcomes following transvaginal hybrid NOTES cholecystectomy (TVC), a consensus regarding safety based on comparative studies has yet to be reached. The aim of this systematic review and meta-analysis was to compare safety and clinical outcomes of TVC with conventional laparoscopic cholecystectomy (CLC) for the treatment of benign gallstone disease.
Methods
A comprehensive search for published studies comparing TVC and CLC was performed. Review of each study was conducted and data were extracted. All pooled outcome measures were determined using random-effects models.
Results
Data were retrieved from 14 studies describing 1,145 patients. There was no difference in total complications (POR = 0.68; 95 % CI 0.40–1.14; P = 0.14), incidence of bile duct injury (POR = 1.33; 95 % CI 0.31–5.66; P = 0.70), Clavien–Dindo Grade II (POR = 0.48; 95 % CI 0.14–1.60; P = 0.23) or Grade III (POR = 0.63; 95 % CI 0.24–1.65; P = 0.34) complications between TCV and CLC. Time of return to normal activities was significantly reduced in the TVC group (WMD = −4.86 days; 95 % CI −9.33 to −0.39; P = 0.03), and there was a non-significant reduction in postoperative pain on days 1 (WMD = −0.80; 95 % CI −1.60 to 0.01; P = 0.05) and 3 (WMD = −0.89; 95 % CI −1.77 to −0.01; P = 0.05).
Conclusions
TVC is safe when performed by appropriately trained surgeons and may be associated with a faster return to normal activities and decreased postoperative pain.
