Summary
Lateral internal sphincterotomy effectively treats anal fissures and hemorrhoids, with high success rates and minimal incontinence. Postoperative anal pressures normalize, maintaining long-term results.
Area of Science:
- Colorectal Surgery
- Gastroenterology
- Surgical Innovation
Context:
- Anal fissures and hemorrhoids are common anorectal conditions.
- High anal resting pressure is a contributing factor to anal fissure pain.
- Lateral internal sphincterotomy is a surgical option for these conditions.
Purpose:
- To evaluate the efficacy and long-term outcomes of individualized lateral internal sphincterotomy.
- To assess the impact of the procedure on anal manometry.
- To determine the incidence of postoperative incontinence.
Summary:
- 75 patients with anal fissure or hemorrhoids underwent lateral internal sphincterotomy.
- High symptom-free rates (97% for fissures, 84% for hemorrhoids) were observed at 3 months and 3 years.
- Significant reductions in maximum resting and medium anal pressures were noted, with normalization in most patients.
- Only one patient reported minor incontinence, with no significant difference in manometric results between 3 months and 3 years.
Impact:
- Demonstrates the long-term effectiveness and safety of lateral internal sphincterotomy.
- Provides evidence for the procedure's role in normalizing anal pressures.
- Offers valuable data for surgical decision-making in treating anal fissures and hemorrhoids.
