Efficacy of 0.2% GTN in Reducing Duration of Wound Healing after Fistulectomy

OBJECTIVE: To analysis the efficacy of 0.2% GTN in patients undergoing fistulectomy for fistula in ano low variety in terms of early wound healing. METHODOLOGY: A randomized controlled trail was conducted at general surgery department of Liaquat University Hospital Hyderabad from February 2013 to August 2013 among patients with low anal fistula. All participants underwent fistulectomy by a consultant general surgeon. Patients were divided into two groups using lottery methods. Group A treat fistula in ano with 0.2% glyceryl trinitrate ointment and group B treat fistula in ano without 0.2% glyceryl trinitrate ointment and wounds covered with pyodine soaked dressings. All patients were discharged on second postoperative day. Wound healing was assessed weekly for six weeks. Parameters of incomplete wound healing such as discharge, perineal irritation and pain were noted. Presence of granulation tissue at the end of 6 weeks was considered as sign of healing. Data was collected via study proforma. RESULTS: This study was conducted on 94 patients in Liaquat University Hospital Hyderabad. In GTN group 35(74.46%) were male while in Control group 38(80.85%) were male. In GTN group mostly observed single opening 37(78.72%) cases while in control group 35(74.46%) cases. The healing time in GTN Group was found to be between 21-36 days (mean 26.38 days), while the healing time control group was 32-46 days with a mean of 38.64 days (P. value <0.001). The complications were also found significantly higher in the control group CONCLUSION: In conclusion our study revealed that postoperative 0.2% GTN after fistulectomy can be used as a primary treatment of low fistula in ano as a shorter period of time for wound to early heal and the less incidence of complications is comparable to that of control group. Key words: fistula in ano, 0.2% GTN, Effectiveness

Objectives: To compare the efficacy of 0.2% glyceryl trinitrate ointment versus internal sphincterotomy after hemorrhoidectomy. Study Design: Randomized Controlled Trial. Setting: Department of Surgery Unit III, at Lahore General Hospital, Lahore. Period: 6 months (August 2017 to February 2018). Material & Methods: The OPD of the Department of Surgery included 124 patients who satisfied the inclusion criteria. There were two groups of patients, Group A and Group B. Group-A was told to use gloved finger three times daily for 0.2 percent GTN ointment topically. For Group B, lateral internal sphincterotomy was performed as day care procedure. On visit, patients were assessed for pain relief by using VAS. All data was collected using a pre-designed (attached) proforma. In SPSS v23.0 the data were input and analyzed. It was stratified for age, sex, disease duration and hemorrhoid stage. The effectiveness of both groups was compared by using a p-value of 0.05 as significant for a chi-square test. Results: Male predominance; in group-A, 41(66.1%) patients were male and 21(33.9%) were female, while in group-B, 52(83.9%) patients were male and 10(16.1%) were females. Efficacy was found in 11(17.7%) patients in group-A (0.2% GTN) while in 25(40.3%) patients in group-B (Internal sphincterotomy) with p-value of 0.006 which is statistically significant. Conclusion: Open hemorrhoidectomy internal sphincterotomy is an effective method to reduce pain after hemorrhoidectomy in contrast to Glyceryl Trinitrate (GTN) topical cream of 0.2 percent.

Efficacy of Glyceryl Trinitrate Ointment for Perianal- Intrarectal Local Anesthesia in Transrectal Ultrasound- Guided Prostate Biopsy- Compared to Topical Lignocaine

Objective: Anorectal pain and discomfort during transrectal ultrasound (TRUS)-guided prostate biopsy is an important issue of this procedure. Therefore present study was designed to compare whether the use of topical glyceryl trinitrate (GTN) ointment or lignocaine gel is more effective as an adjunct to periprostatic nerve block (PPNB) in reducing pain associated with transrectal ultrasound (TRUS)-guided prostate biopsy. Methods: In all, 120 consecutive patients having their first TRUS-guided prostate biopsy were randomized to receive either 0.4% GTN ointment or 2% lignocaine gel, 10 minutes or 5 minutes respectively before biopsy. All patients had a biopsy preceded by an injection with 5 ml of 2% lignocaine local anaesthesia. Results: A 100-point visual analogue score was used to record overall pain due to the presence of the probe, the biopsy itself and pain after the procedure. There was no significant difference in age, PSA level and prostate volume between the groups. There was a significantly lower mean pain score due to probe insertion, in the GTN than lignocaine group (18.32 vs 37.48, P < 0.001); pain perception was lower for the whole procedure in the GTN group (16.59 vs 35.17, P < 0.001); and was most pronounced in men aged d”65 years (21.45 vs 40.7, P < 0.001). Five patients (8.3%) in the GTN group complained of headache. Conclusion: So it can be concluded that, topical GTN ointment is safe and effective in reducing the discomfort and pain associated with TRUS-guided prostate biopsy, in particular the insertion of the ultrasound probe. It might be of maximum benefit in the younger patient(d”65years). Bangladesh Journal of Urology, Vol. 21, No. 1, January 2018 p.14-19

Comparative Study of 0.2% Glyceryl Trinitrate Ointment for Pain Reduction after Hemorrhoidectomy Surgery

Context Hemorrhoid is one of the most common diseases in both, men and women, affecting half of the world's population over the age of 50. Aims The aim of this study was to evaluate the analgesic effects of local ointment of glyceryl trinitrate ointment (GTN) after hemorrhoidectomy. Methods and Materials In this randomized double-blind, placebo-controlled study, the patients were grouped as the treatment, that is GTN, and placebo (P) group. After surgery, 0.2% gelatin GTN ointment (250 mg), and P ointment (n = 20 for each group) were applied topically on 1 cm on the anus using a standard ruler, three times a week in respective groups. visual analog scale was used to assess the intensity of the pain and complications of the drugs were observed at 6, 12, 18, and 24 hours. Statistical Analysis Used Data and questionnaires were analyzed statistically using SPSS17 software and results were recorded in the tabular form. Results Six hours after the application of the ointment, no significant difference was found among the groups, however, after 12, 18, and 24 hours significant reduction in pain was seen in GTN group, which was least after 18 hours. The mean values of the total pain score in the first 24 hours after surgery in the GTN group were 3.15 and 5.45 in the P group which were statistically significant. Nonetheless, headache was significantly increased in the GTN group. Conclusion Simple and safe topical GTN ointment can reduce the pain after hemorrhoidectomy, leading to the reduced need of other analgesics.

A proper application of chemotherapeutic agent at the site of anal fissure: a major concern in healing anal fissure

Background: To show the efficacy of chemotherapeutic agent by special emphasis on its proper application at the site of anal fissure.Methods: All patients were seen in outpatient department and were initially started with 0.2% Glyceryl trinitrate ointment along with sitz bath and psyllium fiber as a primary treatment while 2% diltiazem cream reserved for refractory cases. The follow up visits were made weekly for perianal pain relief and ulcer healing rate.Results: Results in terms of healing of anal fissure and perianal pain relief in 2 or 4 weeks duration were recorded in SPSS version 17. 0.2% GTN ointment showed 75% results in 2 weeks. While complete response was achieved in 95% cases in 4weeks. 2% diltiazem responded in 98% cases in 2 weeks. Non-compliant (2%) abandoned the medical treatment early in the course and proceeded for surgery where 99.99% results were seen in 2weeks only.Conclusions: Conservative treatment is the gold standard for managing anal fissure. Effective counseling of proper application of ointment at the site of anal fissure is emphasized, which is usually failed by the patient due to intense, excruciating peri anal pain and spasmodic sphincter contraction which led them to proceed to surgery.
