Argon Plasma Coagulation in Open Excisional Hemorrhoidectomy

This prospective single-center randomized clinical trial evaluates whether the use of argon plasma coagulation (APC) during open excisional hemorrhoidectomy reduces postoperative pain and perioperative morbidity compared with conventional monopolar coagulation in adults with symptomatic grade III-IV hemorrhoids requiring surgical treatment. A total of 100 participants will be randomized in a 1:1 ratio to open hemorrhoidectomy performed with APC or open hemorrhoidectomy performed with monopolar coagulation. In two arms, the severity of pain will be assessed from day 1 to day 7 postoperatively, both before and after taking analgesics. Additional assessments will be conducted on days 14 and 28 post-surgery, as well as during the first and second defecation using a visual analog scale (VAS). Early postoperative complications, including intraoperative and postoperative bleeding, burning sensation and itching will be evaluated. Long-term complications such as anal canal stenosis, perianal scar deformation, and disease recurrence will be assessed six months after surgery using digital examination performed by consultant proctologist. The goal of this clinical trial is to discover the safety and efficacy of open excisional hemorrhoidectomy for hemorrhoids III-IV grade using argon plasma coagulation.

Topical Nifedipine 0.3% Plus Lidocaine 1.5% for Uncomplicated Hemorrhoidal Disease

The goal of this observational study is to evaluate the effectiveness of topical nifedipine 0.3% plus lidocaine 1.5% for uncomplicated hemorrhoidal disease. The main question it aims to answer is: Does topical nifedipine 0.3% plus lidocaine 1.5% lower symptoms in patients with uncomplicated acute hemorrhoidal disease? Participants already taking nifedipine 0.3% plus lidocaine 1.5% as part of their regular medical care for hemorrhoidal disease will undergo four visits over a 30-day period, including two telephone contacts and two in-person visits.

Acupuncture for Post-hemorrhoidectomy Pain Control

The goal of this clinical trial is to learn if acupuncture improves pain control after hemorrhoidectomy in patients with symptomatic hemorrhoids. It will also learn about the safety of using acupuncture in surgical patients. The main questions it aims to answer are: Does acupuncture lower the maximal pain intensity after hemorrhoidectomy? Does acupuncture reduce analgesics requirement, length of hospital stay and quality of recovery? Researchers will compare fully active acupuncture to a sham treatment (a look-alike procedure with minimum acupuncture stimulation) to see if active acupuncture works to improve pain control. Participants will: Receive acupuncture treatment for 7 times over first 5 days after surgery. Visit the clinic once 2 weeks after surgery for checkups and tests. Keep a diary of their symptoms and the number of times they take pain-killers.

Postoperative Pain in the Surgical Treatment of Hemorrhoids: Conventional Hemorrhoidectomy With a Monopolar Electric Scaler VS Bipolar Energy With Caiman® (Aesculap®)

To demonstrate that postoperative pain secondary to Milligan and Morgan hemorrhoidectomy with Caiman® (AESCULAP®) and subsequent oral conventional analgesia is at least not greater than that generated after hemorrhoidectomy with monopolar diathermy and intravenous analgesia with care home at discharge.
