Topical Sucralfate Decreases Pain After Hemorrhoidectomy and Improves Healing: A Randomized, Blinded, Controlled Study

Oral and topical sucralfate is regularly used in ulcers of gastrointestinal tract, vaginal and perianal excoriations, and radiation burns. This study was designed to determine whether there was any advantage of topical application of sucralfate in reducing postoperative pain and promoting wound healing after open hemorrhoidectomy in patients with Grades III or IV hemorrhoids. A total of 116 patients were randomly assigned to receive sucralfate cream (sucralfate group) or placebo cream (control group) applied to the surgical site. Weekly pain score was evaluated by using Visual Analog Scale. The amount of analgesic tablets consumed in each week also was assessed. At the end of four weeks, two independent surgeons assessed the wound healing. There was no significant difference in age, gender distribution, and number of excised hemorrhoid piles between the two groups. Patients in the topical sucralfate group experienced significantly less pain at Day 7 (Visual Analog Scale +/- standard error of the mean, 3.7+/-0.3 vs. 6.1+/-0.7; P<0.002) and at Day 14 (1.6+/-0.2 vs. 3.1+/-0.6; P<0.01). Likewise patients who received sucralfate cream used less analgesic tablets compared with the placebo group. In the sucralfate group, the overall wound healing ranked significantly better than in controls (P<0.02). Topical sucralfate significantly reduces pain at Days 7 and 14 after hemorrhoidectomy and promotes faster wound healing compared with that of a placebo.

Clinical Experience with a Circular Stapled Hemorrhoidopexy without Circular Anal Dilator (CAD)

Purpose: The circular stapled hemorrhoidopexy (SH) reduces mucosal prolapse and interrupts the end branches of the upper hemorrhoidal artery through a suitable instrument, Procedure for Prolapse and Hemorrhoids (PPH). However, there are some technical difficulties in routine use of the circular anal dilator (CAD). The goal of this study was to evaluate the efficacy and the safety of a CSH without use of a CAD. Methods: Between April 2005 and November 2006, 250 patients with Grade III and IV prolapsed hemorrhoids who had undergone CSH with PPH without using a CAD were retrospectively analyzed. The sex and age, the operation time, the type of anesthesia, the number of excised hemorrhoid piles, the degree of hemorrhoids and postoperative pain (consumed analgesics), the hospital stay, the postoperative complications, and the number of follow-up examinations at the outpatient clinic were analyzed. Results: The operation time was 17.76 minutes (10∼35 minutes). Most patients (89%) experienced spinal anesthesia. The degrees of hemorrhoids were Grade III (45%) and Grade IV (55%). The numbers of excised piles were 3 (44%), 4 (43%), and more than 5 (13%). The number of consumed postoperative analgesics was 0.97 times (mean). The mean hospital stay was 2.83 days. The postoperative complications were pain, bleeding, and urinary retention. Conclusions: A CSH without use of a CAD was an effective and safe surgical modality compared with other procedures for treating hemorrhoids. This procedure is feasible and convenient. The procedure is a new alternative in the treatment of severe hemorrhoids.

Hemorrhoids: an experimental model in monkeys

Hemorrhoids are a matter of concern due to a painful outcome. We describe a simple, easy and reliable experimental model to produce hemorrhoids in monkeys. 14 monkeys (Cebus apella) were used. After general anesthesia, hemorrhoids were induced by ligation of the inferior hemorrhoidal vein, which is very alike to humans. The vein was located through a perianal incision, dissected and ligated with a 3-0 vicryl. The skin was sutured with a 4-0 catgut thread. Animals were kept in appropriate cages and evaluated daily. Nine days later there were hemorrhoidal piles in the anus in fifty percent (50%) of the animals. Outcome was unremarkable. There was no bleeding and all animals showed no signs of pain or suffering. This is an affordable and reliable experimental model to induce hemorrhoids for experimental studies.
