Clinical Study on Application of Hemorrhoidectomy by Anal Canal Dilatation for Grade III or IV Internal Hemorrhoid Accompanied Anal Fissure

Abstract

Background and Aim: This study aimed to evaluate the efficacy of a novel surgical technique, hemorrhoidectomy by anal canal dilatation, for treating Grade III or IV internal hemorrhoids accompanied by anal fissures. Methods: A total of 202 patients were included in the study, with 96 patients in the study group undergoing hemorrhoidectomy by anal canal dilatation and 106 patients in the control group receiving the traditional Milligan-Morgan operation. Postoperative outcomes were assessed, including recovery rates, analgesic usage and duration of defecation difficulties. Results: The average recovery rate in the study group was 95.8%, significantly higher than the control group's rate of 86.8% (p<0.05). Additionally, the mean duration of analgesic use was significantly lower in the study group (2 days) compared to the control group (3 days) (p<0.05). The average duration of difficulty in defecation post-surgery was also shorter in the study group (2.0±0.75 days) compared to the control group (6.6±0.37 days) (p<0.05). Conclusion: The results indicate that hemorrhoidectomy by anal canal dilatation is an effective and satisfactory alternative to traditional methods for treating Grade III or IV internal hemorrhoids accompanied by anal fissures. This technique not only enhances recovery rates but also minimizes postoperative pain and complications.
