Evaluation of the clinical efficacy and safety of TST33 mega hemorrhoidectomy for severe prolapsed hemorrhoids.

BACKGROUND

The pathogenesis of hemorrhoids is mainly anal cushion prolapse. Although the traditional treatment has a certain curative effect, it is not ideal. The remission rate of postoperative symptoms is low. Even if temporary remission is achieved, patients with hemorrhoids easily relapse after 1-2 years. The new technique of using staplers to treat prolapsed hemorrhoids has good therapeutic effects in clinical practice.

AIM

To explore the effect of TST33 mega stapler prolapse and hemorrhoid mucosal resection in the treatment of patients with severe prolapsed hemorrhoids.

METHODS

A total of 204 patients with severe prolapse hemorrhoids who were admitted to the department of anorectal in our hospital from April 2018 to June 2020 were selected, and the patients were randomly divided into group A and group B with 102 cases in each group using a randomized controlled clinical research program. Patients in Group A were treated with a TST33 mega stapler and hemorrhoid mucosal resection to treat prolapse, and patients in Group B were treated according to the Procedure for Prolapse and Hemorrhoids; the operation time, intraoperative blood loss, hospital stay, the difference in operation time, intraoperative blood loss, hospitalization time, pain degree before and after operation, degree of anal edema, anal Wexner score, and surgical complications were compared between the two groups of patients.

RESULTS

The operation time, intraoperative blood loss and hospitalization time in Group A were significantly lower than those in Group B ( < 0.05). The cure rate of Group A was 98.04%, compared with 95.10% cure rate of Group B, and the difference was not statistically significant ( > 0.05). The visual analogue scale (VAS) at 12 h and 24 h postoperatively in Group A were significantly lower than those in Group B ( < 0.05). The comparison of the VAS scores between Group A and Group B at 48 h, 72 h and 96 h postoperatively revealed that the difference was not statistically significant ( > 0.05). One day postoperatively, the degree of perianal edema in Group A was compared with that in Group B, and the difference was not statistically significant ( > 0.05). Seven days postoperatively, the degree of perianal edema in Group A was significantly lower than that in Group B ( < 0.05). The comparison of anal Wexner scores between the two groups preoperatively and at 1 mo, 3 mo and 6 mo postoperatively showed that the difference was not statistically significant ( > 0.05). The Wexner scores of the two groups at 1 mo, 3 mo and 6 mo postoperatively were significantly lower than the scores preoperatively ( < 0.05). The postoperative complication rate of Group A was 2.94% lower than that of Group B (11.76%), which was statistically significant ( < 0.05).

CONCLUSION

TST33 mega anastomotic hemorrhoidectomy treatment for patients with severe prolapse hemorrhoids, leads to less postoperative pain, the rapid recovery of perianal edema and has fewer complications.
