Local anal hypothermia with a frozen finger: a treatment for acute painful prolapsed piles

Cooled (4°C) lidocaine during office cystoscopy improves patient satisfaction and comfort: A prospective, randomized, double-blind, controlled study

INTRODUCTION

Office-based flexible cystoscopy is often associated with considerable discomfort in male patients. We devised this study to prospectively evaluate the efficacy of cooling intraurethral lidocaine jelly to 4°C prior to use in office-based cystoscopy in an effort to reduce male patient discomfort.

METHODS

A total of 600 male patients scheduled for office diagnostic cystoscopy were enrolled and randomized into three groups for a prospectively controlled, double-blind study. Each group received one of the three methods of intraurethral lubrication: plain room temperature lubricant (control) (CON), room temperature lidocaine (LI), or lidocaine at 4°C (LI4°C). Perceived pain was recorded on a Likert visual analog scale (VAS) of 1-10 where 0=no pain and 10=excruciating pain. Kruskal-Wallis test assessed the efficacy of cooling lidocaine compared to room temperature lidocaine and control. Subjective pain reporting was corroborated with instantaneous objective pulse rate recording eliminating perception bias.

RESULTS

There was no significant difference in cystoscopy duration between all groups. Mean pain scores (mean ± standard deviation) were 4.05±0.91, 2.74±1.01, and 1.8±0.84, respectively, for groups CON, LI, and LI4°C (p=0.02). There was a 32.34% reduction in the mean pain score of LI and a further reduction of 34.3% was achieved in LI4°C when compared to CON. Body mass index (BMI) and prostate weight had a significant positive correlation with pain score, whereas no such correlation was found with age.

CONCLUSIONS

Cooling lidocaine to 4°C provides additional analgesic benefit in men undergoing office cystoscopy and increases compliance.

Intrarectal ice application prior to transrectal prostate biopsy: a prospective randomised trial accessing pain and collateral effects

Objectives

To analyze the efficacy of intrarectal ice application as an anesthetic method prior to transrectal ultrasound (TRUS) guided prostate biopsy.

Materials and Methods

A total of 120 consecutive men were included into the study prospectively. Patients were equally randomized as group 1 and 2 with 60 patients each. Ice was applied as an anesthetic method 5 minutes before procedure to the patients in group 1. Patients in group 2 were applied 10 ml of 2% lidocaine gel 10 minutes before procedure. Twelve core biopsy procedure was performed for all patients. The pain level was evaluated using a visual analogue scale (VAS).

Results

Median pain score was 3.5 (1-8) in group 1 and 5 (1-8) in group 2. There is significantly difference between groups regarding the mean sense of pain level during the procedure. (p=0.007) There was also no difference in complications between two groups about presence and duration of macroscopic hematuria and rectal bleeding.

Conclusions

Intrarectal ice application prior to TRUS prostate biopsy has an effect on reducing pain. Development of new techniques about cold effect or ice can make this method more useful and decrease complication rates.

A novel device reduces anal pain after rubber band ligation: a randomized controlled trial

BACKGROUND

Anal pain is a well-known sequel of rubber band ligation (RBL). A plastic device, the anal cooler which can be frozen in a freezer, has been developed to reduce anal pain. It contains a mixture of glycols and has a minimum temperature of 4 °C. This study was designed to investigate the efficacy of the anal cooler in pain relief after RBL.

METHODS

Between 2009 and 2010, 100 patients who underwent RBL were prospectively randomized into an anal cooler group (n = 50) or a control group (n = 50). The anal cooler group was instructed to use the cooler when they had pain. All patients were asked to keep a pain diary (0 = no pain; 10 = extreme pain), and follow-up was performed after 3-6 weeks.

RESULTS

It was found that 24/50 patients (48 %) in the anal cooler group and 31/50 (62 %) in the control group needed oral analgesics (NS). In total, 36/50 patients (72 %) used the anal cooler. Of these, 9/36 patients (25 %) noticed improvement. Of the remaining 27/36 patients (75 %) who did not notice improvement, 5/36 patients (14 %) found the insertion of the cooler uncomfortable and 1/36 patients (3 %) experienced nausea. No complications occurred during or after the use of the cooler. The 14/50 patients (28 %), who did not use the cooler, had a lower post-banding pain score compared with patients who used the cooler (1.4 vs 6.4; P < 0.001).

CONCLUSIONS

Although post-banding pain after RBL is usually mild, the anal cooler seems to relieve anal pain in 25 % of the patients who used the device.

'Frozen finger' in anal fissures

Acute anal fissures are usually managed by various invasive and non-invasive modalities ranging from simple lifestyle changes to chemical and surgical sphincterotomies. Frozen finger, prepared using a water-filled ordinary rubber glove, was successfully used in one hundred patients, thus providing a cost-effective and simple solution to the problem.

Stapled mucosectomy for acute thrombosed circumferentially prolapsed piles: a prospective randomized comparison with conventional haemorrhoidectomy

OBJECTIVE

Stapled mucosectomy has been developed as an alternative to conventional haemorrhoidectomy for the elective treatment of haemorrhoids, but has not been assessed in the emergency setting. The aim of this study was to compare this technique with a conventional procedure for acute thrombosed circumferential prolapsed haemorrhoids.

PATIENTS AND METHODS

A prospective randomized comparison of conventional Milligan-Morgan haemorrhoidectomy and stapled mucosectomy was carried out on 35 consecutive patients presenting with acute thrombosed circumferential prolapsed haemorrhoids. Operative data, postoperative stay, pain assessment and persistent symptoms were compared at discharge and at 2 week and 6 week review. Additionally at 6 week review the time to return to work was recorded and an endoanal ultrasound was carried out.

RESULTS

Thirty patients were randomized and followed up for six weeks. Although postoperative stay and in-hospital analgesia were the same, patients from the stapled group reported significantly more pain at discharge. However, by 2 weeks the conventional group reported significantly higher pain scores particularly on passing stool. By this stage over half the stapled group patients reported no pain at all. More patients in the conventional group complained of persistent symptoms of pain, bleeding and discharge at 2 week and 6 week review with 20% requiring readmission compared with none in the stapled group. The median return to work was significantly shorter for the stapled group (14 days vs 28 days, P < 0.05). Although all patients claimed to be continent, two patients from each group had ultrasonic evidence of internal sphincter damage.

CONCLUSION

Stapled mucosectomy for acute thrombosed circumferential piles is feasible and may result in less pain, a more rapid resolution of symptoms and an earlier return to work compared with a conventional procedure.
