Transanal hemorrhoidal dearterialization (THD) versus stapled hemorrhoidopexy (SH) in treatment of internal hemorrhoids: a systematic review and meta-analysis of randomized clinical trials

Although conventional hemorrhoidectomy proved effective in treatment of hemorrhoidal disease, postoperative pain remains a vexing problem. Alternatives to conventional hemorrhoidectomy as transanal hemorrhoidal dearterialization (THD) and stapled hemorrhoidopexy (SH) were described. The present meta-analysis aimed to review the randomized trials that compared THD and SH to determine which technique is superior in terms of recurrence of hemorrhoids, complications, and postoperative pain.
Electronic databases were searched for randomized trials that compared THD and SH for internal hemorrhoids. The PRISMA guidelines were followed when reporting this meta-analysis. The primary endpoint of the analysis was persistence or recurrence of hemorrhoidal disease. Secondary endpoints were postoperative pain, complications, readmission, return to work, and patients’ satisfaction.
Six randomized trials including 554 patients (THD = 280; SH = 274) were included. The mean postoperative pain score of THD was significantly lower than SH (2.9 ± 1.5 versus 3.3 ± 1.6). 13.2% of patients experienced persistent or recurrent hemorrhoids after THD versus 6.9% after SH (OR = 1.93, 95%CI = 1.07–3.51, p = 0.029). Complications were recorded in 17.1% of patients who underwent THD and 23.3% of patients who underwent SH (OR = 0.68, 95%CI 0.43–1.05, p = 0.08). The average duration to return to work after THD was 7.3 ± 5.2 versus 7.7 ± 4.8 days after SH (p = 0.34). Grade IV hemorrhoids was significantly associated with persistence or recurrence of hemorrhoidal disease after both procedures.
THD had significantly higher persistence/recurrence rate compared to SH whereas complication and readmission rates, hospital stay, return to work, and patients’ satisfaction were similar in both groups.
