Topical Lidocaine 23%/Tetracaine 7% Ointment for Post-Hemorrhoidectomy Analgesia: A Randomized Controlled Trial

The goal of this clinical trial is to learn if a topical ointment containing two local anesthetics (lidocaine 23% and tetracaine 7%) can reduce pain after hemorrhoid surgery in adults. The main questions it aims to answer are: * Does the ointment lower post-defecation pain movements in the first 10 days after surgery? * Does the ointment lower overall daily pain in the 10 days after surgery? * Does the ointment reduce the need for rescue pain medication (tramadol)? Researchers will compare the lidocaine/tetracaine ointment to a placebo (a look-alike ointment that contains no active drug) to see if the active ointment works better to reduce pain after hemorrhoid surgery. Participants will: * Apply the ointment or placebo to the anal area every 12 hours for 10 days after surgery * Rate their pain on a scale from 0 to 10 each day, including pain after bowel movements/defecation * Record how many times they take rescue pain medication each day * Receive check-in calls/mesages from the research team after surgery

Comparison of Laser Hemorrhoidoplasty Versus Conventional Milligan Morgan Hemorrhoidectomy in Grade II and III Hemorrhoids

Hemorrhoidal disease is one of the most common anorectal disorders. Conventional Milligan Morgan Hemorrhoidectomy remains the standard treatment but is associated with considerable postoperative pain. Laser Hemorrhoidoplasty has emerged as a minimally invasive alternative. This randomized controlled trial compares postoperative pain, patient satisfaction, and hospital stay between Laser Hemorrhoidoplasty and conventional hemorrhoidectomy in patients with Grade II and Grade III hemorrhoids.

Traditional Medicine Syndromes in Internal Hemorrhoids: a Cross-Sectional Study

This study aims to investigate the characteristics of Traditional Medicine (TM) syndromes in patients diagnosed with internal hemorrhoids at Le Van Thinh Hospital. Internal hemorrhoids are a common anorectal disorder, and their classification in Traditional Medicine remains inconsistent. The study will examine the prevalence of TM syndromes in patients with internal hemorrhoids and assess the correlation between Goligher's classification and TM diagnoses. The study will follow a cross-sectional observational design with an estimated 178 participants. Eligible patients are 18 years or older, diagnosed with internal hemorrhoids, and willing to participate. The primary outcomes include the prevalence of TM syndromes in internal hemorrhoids, severity classification according to Goligher's scale, and correlation analysis between TM syndromes and clinical severity. The study has received approval from the Institutional Review Board (IRB) of the University of Medicine and Pharmacy at Ho Chi Minh City and will be conducted from December 2024 to April 2025 at Le Van Thinh Hospital, Vietnam.
