A Comparison Between the Results of Fissurectomy and Lateral Internal Sphincterotomy in the Surgical Management of Chronic Anal Fissure

Abstract

In the surgical treatment of chronic anal fissure not responding to conservative management, LIS may be the better treatment and, perhaps, the preferable surgical technique with fewer total complications (P < 0.005).

A prospective, randomize study of comparison of lateral internal sphincterotomy versus Lord’s anal dilatation in chronic anal fissure

“…These observations were in accordance with observations of previous studies. 6,[13][14][15][16][17] In this study, pain score in first 24 hours was significantly higher in LAD group as compared to LIS group reason might be due to inter-individual difference in the application of force in anal dilatation, intra-operatively. 4 This difference was negated in subsequent days and difference at the time of discharge was non-significant.…”

Advancement flap in the management of chronic anal fissure: a prospective study

“…It was recognized as effective therapy for CAF for many years and afterwards it was abandoned due to its consequences, such as keyhole deformity that may lead to faecal incontinence [16]. Nevertheless, it has recently been reconsidered for treating CAF both in children and in adults with success [19][20][21]. To improve the results and to reduce the incidence of complications, the fissurectomy has been associated with pharmacological sphincterotomy.…”

Fissurectomy combined with anoplasty and injection of botulinum toxin in treatment of anterior chronic anal fissure with hypertonia of internal anal sphincter: a pilot study

“…Fissure excision without a procedure on the internal sphincter is an old operation and was championed by Ashton in 1854 [25]. It was recognized as effective therapy for CAF for many years, and afterwards it was abandoned due to its consequences such as keyhole deformity that may lead to faecal incontinence [7]; only recently it has been reconsidered for treating CAF in adults [26][27][28]. The fissurectomy has been associated with surgical or pharmacological sphincterotomy.…”
