Purpose
While the first defecation pain is a problem following hemorrhoidectomy, it is unknown whether the stool consistency has an influence on pain. This pilot study aimed to investigate whether the intensity of defecation pain varied according to stool consistency.
Methods
This prospective cohort study evaluated patients who underwent hemorrhoidectomy in combination with injection sclerotherapy for grade III or IV hemorrhoids. The pain intensity and stool form during the first postoperative defecation were self-recorded by the patients using a visual analogue scale (score of 0–10) and Bristol Stool Form Scale, respectively. The patients were classified into 3 groups according to stool consistency, and the intensity of defecation pain was compared among the groups using analysis of variance.
Results
A total of 61 patients were eligible for this study and were classified into the hard stool (n=15), normal stool (n=21), and soft stool groups (n=25). No significant intergroup differences were identified in the intensity of pain at defecation (P=0.29).
Conclusion
This pilot study demonstrated that there were no clear differences in pain intensity during the first defecation after surgery among the 3 groups with different levels of stool consistency.

Purpose

Injection sclerotherapy for hemorrhoids has been performed for many years. Currently, 5% phenol in almond oil (PAO) and aluminum potassium sulfate and tannic acid (ALTA) are used as the agents. The purpose of this study was to compare the efficacy of the two agents.

Methods

A retrospective study was conducted involving 135 patients who underwent injection therapy for grade 3 hemorrhoids for the first time between 2013 and 2014 (PAO, 55 patients; ALTA, 80 patients). The efficacy was established as the proportion (%) of patients without symptoms such as hemorrhage and prolapse one year after treatment. We investigated four factors—sex, age, number of hemorrhoids, and agent—that might have an influence on the efficacy.

Results

The efficacies of ALTA and PAO one year after treatment were 75% and 20%, respectively. Only the agent was a significant independent factor (P < 0.01).

Conclusion

The results suggest that ALTA is markedly more useful than PAO for injection sclerotherapy for grade 3 hemorrhoids.
