Segmental resection combined with anoplasty for the treatment of circumferential mixed hemorrhoids

ABSTRACT

Circumferential mixed hemorrhoids are very difficult to treat non-surgically. Therefore, it is important to explore the surgical methods for its complete resolution as well as maintenance of normal anal anatomy and function. The present study was designed to evaluate the effect of segmented and plastic hemorrhoidectomy (SPH) on patients with circumferential mixed hemorrhoids. A total of 300 patients with circumferential mixed hemorrhoids were divided into experimental group (n=150) undergoing SPH and control group (n=150) undergoing Milligan-Morgan hemorrhoidectomy. There were no differences in cure and effectiveness rates between two groups. Compared with the control group, patients in the experimental group had shorter healing time (15.7±1.3 vs 12.5±0.7 days) and recovery to normal activity (18.5±2.7 vs 14.7±1.2 days). In addition, anal function of all patients in the experimental group was normal during short- and long-term follow-up. However, more cases in the control group showed anal dampness and itching, and poor control of intestinal liquid. Compared with the control group, patients in the experimental group had better outcomes in overall anal function and smoothness at 6, 12, and 18 months after operation as well as patient satisfaction. Furthermore, the rating in the visual analogue scale for defecation pain and edema in the experimental group was less than that in the control group. SPH was more effective, had fewer complications, better protection of anal function, and a better cosmetic result.
