Umbilical closure using 2‐octyl cyanoacrylate in transumbilical laparoscopic adrenalectomy: A randomized controlled trial

OBJECTIVES To evaluate postoperative pain and esthetic outcomes in patients undergoing transumbilical laparoscopic adrenalectomy with wound closure using 2-octyl cyanoacrylate. METHODS A total of 26 patients who underwent laparoscopic adrenalectomy with the transumbilical approach and agreed to participate in this study were included. Patients were randomly divided into two groups: the 2-octyl cyanoacrylate group (Glue group) or the non-use group (non-Glue group). A single surgeon (AM) carried out all procedures between 2014 and 2017. RESULTS There were no significant differences in the clinical background of the Glue and non-Glue groups. The number of patients with moderate or high levels of pain in the resting/moving period on postoperative days 1, 2 and 3 was 6/10 (46%/77%), 6/9 (46%/69%) and 3/5 (23%/38%) in the non-Glue group, and 5/7 (38%/54%), 2/7 (15%/54%) and 1/3 (8%/23%) in the Glue group. These differences were not significant. In the subgroup analysis of patients aged
