“…A total of 86 studies were excluded for solely discussing laparoscopy (n = 15), comparing results of laparoscopic reversal versus open reversal of left-sided colostomy (n = 11), treatment of diverticulitis (n = 25), video vignettes (n = 4), using other novel techniques of stoma reversal (n = 5), case reports on stoma problems (n = 3) and other articles unrelated to singleport stoma reversal surgery (n = 23). Three previous published articles on this topic from our current collaborative group of authors were excluded [3,15,17], one article was excluded due to inclusion of their more recent manuscript [21], one meta-analysis on this topic was excluded since it had no additional new studies [22], leaving 5 included original articles [13,14,19,23,24]. This appraisal shows that since the introduction of the single-port approach in Hartmann's reversal in 2011 by Smith and Bettinger [13], additional case series have been published on this topic.…”
