Abstract:
Objective:To investigate the clinical effects of the " rectangle plus triangle flaps" methods to repair the post-burn pseudo anal stenosis.
Methods:From Oct. 2014 to Jan. 2017, five cases of pseudo anal stenosis were hospitalized and the durations of their scar contraction were 0.5 to 2 years. Flaps were located: at 3 o′clock and 9 o′clock directions of anus with prone position. Flaps were designed as one rectangle flap plus two triangle flaps. Rectangle flap was located from the exit of the diverticulum (pedicle) to the anus (distal end). Triangle flaps were located between the anus and the distal end of the rectangle flap, perpendicular to the rectangle flap. Flap transfer: ① the rectangle flap was advanced to the anus direction and sutured with the incision edge of the triangle flap closer to the anus; ② the two triangle flaps were rotated by 90 degrees and transferred to the two longitudinal incisions of the rectangle flap.
Results:This design could enlarge the diverticulum exit and shorten its distance to the anus. All flaps survived and were well-healed. The follow-ups at 0.5 to 2 years presented favorable clinical results. No flap contracture, recurrent stenosis, unobstructed defecation or cleaning convenience occurred.
Conclusions:The " rectangle plus triangle flaps" methods was an effective way to repair the post-burn pseudo anal stenosis, which could enlarge the diverticulum exit and relocate the anus by making use of the perianal scar tissue.
