Rhomboid Island Flap Anoplasty in Post- Haemorroidectomy Anal Stenosis

Abstract

Background: Anal stenosis may occur after anal surgery especially after surgical haemorrhoidectomy. Many types of flaps have been described for anal stenosis. We aimed to evaluate the outcome of dermal rhomboid island flap in treatment of post haemorroidectomy anal stenosis. Patients and methods: The current study included twenty patients with a clinical diagnosis of post hemorrhoidectomy anal stenosis underwent rhomboid island flap anoplasty. We assessed the caliber of the anal canal (measured with a conical calibrator), clinical improvement and postoperative complications for all patients. Results: There was high significant improvement in anal calibration with a mean difference obtained on comparing preoperative and 1 month' anal caliber, of 15.95± 1.88 (p < 0.001). Also, there was high significant improvement in CCIS with a mean difference obtained on comparing preoperative and 12 months' CCIS, of 7.55± 1.28 (p < 0.001). The majority of patients had no postoperative complications (85%). Conclusion: The use of Rhomboid Island Flap Anoplasty is a safe and suitable option for the treatment of mild, moderate and severe Post-Hemorrhoidectomy Anal Stenosis.
