The \u201cconverted group\u201d has a significantly higher percentage of patients with severe pelvic adhesions (9\/19 [47.4%]) and pelvic endometriosis (2\/19 [10.5%]), which significantly predicates surgical conversion. The \u201cconverted group\u201d also had a longer duration of surgery (140.94\u2009\u00b1\u200988.73\u2009min, <jats:italic>P<\/jats:italic>\u00a0=\u20090.002) and an increased proportion of \u201cconverted from vNOTES\u201d patients experienced more than 50\u2009ml of intraoperative blood loss (7\/19 [36.9%]).
