Sungurtekin Technique vs. Closed Lateral Internal Sphincterotomy Technique
- Conditions
- Anal Fissure
- Registration Number
- NCT04428697
- Lead Sponsor
- Pamukkale University
- Brief Summary
BACKGROUND: Currently, the lateral internal sphincterotomy is the treatment of choice for a chronic anal fissure. However, the length of the internal sphincter incision varies, due to lack of standardization. Insufficient length increases the risk of recurrence.
OBJECTIVE: To compare a new ultra-modified internal sphincterotomy technique to the closed lateral sphincterotomy for treating chronic anal fissures, based on internal anal sphincter function and postoperative complications.
DESIGN: Prospective, randomized, controlled trial (block randomization method) SETTING: Pamukkale University hospital in Denizli-Turkey PARTICIPANTS: 200 patients with chronic anal fissures INTERVENTION: Patients were randomly assigned to receive either Sungurtekin technique (n = 100; ultra-modified group), or the closed lateral internal sphincterotomy (n = 100; closed-lateral group). Follow-up was 2 years.
MAIN OUTCOME MEASURES: The primary outcome was chronic anal fissure healing. The secondary outcomes were complications, visual analog scale pain scores, sphincter pressures, and incontinence scores.
- Detailed Description
Although the lateral internal sphincterotomy is the treatment of choice for CAF, it has several drawbacks. First, the lower portion of the internal sphincter is nested in the lowermost part of the anus. Thus, an incision from the fissure base up to the dentate line removes support to the inner sphincter structure on the incision site. In our opinion; this is the main cause of different levels of incontinence developing in the postoperative period. Second, the internal sphincter muscle is shorter in women than in men. Therefore, women are at higher risk of postoperative anal incontinence than men. Third, because the lateral internal sphincterotomy is not standardized, the length of the internal sphincter incision varies, depending on the surgeon's discretion and competency. Fourth, an incision that is too short increases in the risk of recurrence.
The investigators believe that this observation could be explained by the fact that the length of the incision required for a lateral internal sphincterotomy procedure has not been standardized

- Primary Outcome Measures
Name Time Method Recurrence 1-24 month It has been reported in the literature that healing was completed in 6-8 weeks in patients undergoing this operation. During this period, it was accepted that the fissure was no longer detected as a visual examination finding and that patient complaints disappeared.
Incontinence Rate 12th month Pre and postoperative fecal continence were scored using the Cleveland Clinic Florida Fecal Incontinence (CCF-FI) scores. Cleveland Clinic Florida (CCF) scores were used to assess the severity of fecal incontinence at baseline, and at 12 months. The scores from 0 indicate perfect continence to a maximum of 20 indicates complete incontinence The CCF FI scale combines loss of flatus, liquid and solid stool, use of a pad and the impact on the quality of life a assess the severity of fecal incontinence.
Complications 1-24 month Urinary retansion,ecchymosis,itching,bleeding,abscess,fistula has been accepted as postoperative complications
Postoperatif pain Postopetaive 3th day The patients asked to record postoperative pain scores with VAS(Visual Analog Scale)Graded from 0.0 to 10.0. and measured postoperative day 3 .As low as possible this pain score value indicates that the patient is exposed to less pain.
