Comparison of clinical outcomes of multi-point umbrella suturing and single purse suturing with two-point traction after procedure for prolapse and hemorrhoids (PPH) surgery.

OBJECTIVES: To compare the clinical outcomes of multipoint umbrella suture and single-purse suture with two-point traction after procedure for prolapse and hemorrhoids surgery (PPH) for the treatment of mixed hemorrhoids.

METHODS: Ninety patients were randomly divided into a PPH plus single-purse suture group (Group A) and a PPH plus multipoint umbrella suture (Group B). All operations were performed by an experienced surgeon. Operation time, width of the specimen, hemorrhoids retraction extent, postoperative pain, postoperative bleeding, and length of hospitalization were recorded and compared. Statistical analysis was conducted by t-test and χ2 test.

RESULTS: There were no significant differences in sex, age, course of disease, and degree of prolapse of hemorrhoids between the two groups. The operative time in Group A was significantly shorter than that in Group B (P < 0.05). However, the incidence rates of submucosal hematoma and incomplete hemorrhoid core retraction were significantly lower in Group B (P < 0.05), whereas the width of the specimens in Group B was greater than that in Group A (P < 0.05). There were fewer redundant skin tags in Group B at three months follow-up. No significant difference in postoperative pain, postoperative bleeding, and time of hospital stay (P > 0.05 for all comparisons) was observed.

CONCLUSION: The multipoint umbrella suture showed better clinical outcomes because of its targeted suture according to the extent of hemorrhoid prolapse.
