Abstract

- Purpose
Perineal procedures are an important surgical option for frail and high-risk patients with rectal prolapse. This study aimed to evaluate the efficacy and safety of combined therapy using injection sclerotherapy, with aluminum potassium sulfate and tannic acid (ALTA), and the Thiersch procedure, using the Leeds-Keio ligament (ALTA-Thiersch).
Methods
This study included 106 consecutive patients (mean age, 81.2 years) who underwent ALTA-Thiersch for rectal prolapse. The procedure was performed under caudal epidural anesthesia. ALTA was injected into the submucosa from the tip of the prolapsed rectum down to the dentate line, circumferentially, at 20 to 40 locations. The ligament tape was placed outside the external sphincter muscle and at an approximate depth of 2 cm into the middle anal canal.
Results
Of 106 patients, rectal prolapse was cured shortly after surgery in 105 patients. An additional tape was inserted in 1 patient who had persistent prolapse. Postoperative complications were observed in 27 patients (25.5%). Fecal impaction occurred in 12 patients; however, since it was temporary, no tape removal was required. Of the 12 cases in which the tape was infected or exposed, 11 required tape removal. There were 18 cases of recurrence at a mean follow-up of 22.1 months. Cumulative recurrence rates at 3 and 5 years were 21.3% and 38.6%, respectively.
Conclusion
ALTA-Thiersch is a simple and safe procedure for rectal prolapse, having reasonable outcomes. The use of the Leeds-Keio ligament for anal encircling can help compensate for the disadvantages of the Thiersch operation.

Abstract

- Purpose
Aluminum potassium sulfate and tannic acid (ALTA; Zion, Mitsubishi Pharma Corp.) is an effective sclerosing agent for internal hemorrhoids. ALTA therapy with a rectal mucopexy (AM) is a new approach for treating hemorrhoidal prolapse. This study compared the early postoperative outcomes of AM surgery with Doppler-guided transanal hemorrhoidal dearterialization and mucopexy (DM) in patients with third-degree hemorrhoids.
Methods
AM surgery was performed on 32 patients with grade III hemorrhoids and was compared with a cohort of 22 patients who underwent DM surgery in a previous randomized controlled trial.
Results
The pain scores during defecation were significantly lower in the AM patients beginning 4 days after surgery. The total use of analgesics 2 weeks postoperatively was significantly lower in the AM patients than in the DM patients (3.5 tablets [range 1.6–5.5] vs. 7.6 tablets [range 3.3–11.9], P=0.04). The length of operation, blood loss, and incidence of postoperative complications were significantly lower in the AM patients than in the DM patients. During 12 months follow-up, recurrence of prolapse occurred in 1 patient who underwent AM surgery.
Conclusion
AM surgery is effective, with lower complication rates and postoperative analgesic requirements, and is a less invasive treatment for patients with grade III hemorrhoids compared to DM surgery.

- Purpose
Perianal injection of bulking agents is an attractive treatment option for patients with mild to moderate fecal incontinence (FI). Various bulking agents have been used for injection therapy, but the optimal injection materials and methods are yet to be standardized. This study aimed to evaluate the effects of injection therapy using aluminum potassium sulfate and tannic acid (ALTA) in the management of FI.
Methods
This study included consecutive patients who underwent ALTA injection therapy for FI at our institution. The procedure was performed with the patient in the jackknife position, under caudal epidural anesthesia. The procedure consisted of a 4-step injection to the 3 main cushions and a multipoint injection to the remaining submucosa of the anal canal.
Results
Seventy-seven patients (mean age, 76 years) were enrolled in the study. The mean Cleveland Clinic incontinence score of 11.9 ± 4.1 at baseline significantly improved to 7.3 ± 5.2 at 3 months following treatment. The mean maximal resting pressure also increased significantly 3 months after the intervention. Postoperative complications were observed in 3 patients (3.9%), and all events were mild. The mean duration of postoperative follow-up was 17.5 months. The cumulative recurrence-free rate at 3 years was 72.4%.
Conclusion
ALTA injection for FI is safe, easy to perform, and provides reasonable mid-term outcomes. Moreover, concomitant anorectal diseases that may be contraindicated by other injectable bulking agents could be treated simultaneously. Therefore, ALTA injection is a promising alternative in the absence of other injectable agents.

Abstract
PDF
A quick hemostatic effect, as well as sclerosing and shrinkage of hemorrhoids, can be attained when internal hemorrhoids are treated by using injection therapy with aluminum potassium sulfate and tannic acid (ALTA), the outcomes of treatment may be similar to those of a hemorrhoidectomy. However, if the type of hemorrhoid or the method of injection is not appropriate for ALTA treatment, complications peculiar to ALTA or recurrence may develop. Accordingly, sufficient understanding of the treatment mechanism of ALTA injection and repeated training for injection are required for effective use of the ALTA treatment.
