Efficacy of Lidocaine Gel Enema After Endoscopic Hemorrhoid Band Ligation for Relief of Post Procedural Pain

November 6, 2019


This clinical trial studies how a Lidocaine Hydrochloride gel enema reduces pain after endoscopic band ligation of internal hemorrhoids. The study will evaluate side effects and efficacy of the enema by recording pain following the procedure.


Study Information

During the band ligation procedure, patients will be randomly assigned to the treatment or control arm. Patients in the treatment arm will receive 15ml enema of Lidocaine gel and patients in the placebo arm will receive oral pain medications. Pain will be assessed at 1 hour, 24 hours, and 48 hours after the procedure by phone calls and patients will be monitored closely by nurses for 4 hours in an observation unit. Pain will be assessed with a numeric pain scale (0-10).


The data that will be collected for each patient includes gender, age, internal hemorrhoids grade, race, BMI, comorbid conditions, pain, and adverse side effects from the medication.


Before being enrolled, patients will undergo a comprehensive metabolic panel and blood count, as well as a urine pregnancy test if necessary. The researchers will exclude any patients with signs or symptoms of liver disease, renal or hepatic impairment, or any other exclusion criteria.
