This prospective, patient-blinded randomized controlled trial will be conducted at Kasr Al-Ainy Hospital, Cairo University. Adult patients with grade III or IV hemorrhoids undergoing elective surgery will be randomized (1:1) to either conventional hemorrhoidectomy or hemorrhoidectomy followed by intra-anal cryotherapy. All patients will undergo standardized preoperative assessment and receive the same postoperative analgesia and care. Postoperative pain will be assessed using the Visual Analogue Scale (VAS), with follow-up at postoperative day 2 and at 1, 2, 3, and 4 weeks.
This prospective, patient-blinded randomized controlled trial will be conducted at the General Surgery Department, Kasr Al-Ainy Hospital, Cairo University. Adult patients (≥18 years) with grade III or IV hemorrhoids who are scheduled for elective surgery will be enrolled. Patients with concomitant anorectal pathology, inflammatory bowel disease, impaired continence, or those requiring synchronous procedures will be excluded. Following informed consent, all patients will undergo standardized preoperative clinical assessment and routine laboratory investigations, with colonoscopy performed when clinically indicated. Participants will be randomized in a 1:1 ratio using computer-generated randomization with allocation concealment by sequentially numbered, opaque, sealed envelopes into either conventional Milligan-Morgan hemorrhoidectomy (control group) or Milligan-Morgan hemorrhoidectomy followed by intra-anal cryotherapy (cryotherapy group). In the cryotherapy group, a sterile ice pack will be inserted into the anal canal for 1 minute immediately after completion of hemorrhoidectomy. Postoperative management will be standardized in both groups, including analgesia, local care, antibiotics, and laxatives. Postoperative Pain will be assessed using the Visual Analogue Scale (VAS).

V-shaped incision around the hemorrhoidal base. The hemorrhoid will be dissected in the submucosal plane to the pedicle, which will be double ligated with a 2/0 Vicryl suture before excision. The procedure will be repeated for all affected hemorrhoids while preserving adequate skin bridges to prevent anal stenosis. Hemostasis will be achieved using cautery.Then, The surgeon will insert the ice pack transanally to the proximal anal canal for 1 minute while the patient remained under general anesthesia.

Pain at rest and after defecation at At day 1 postoperatively
Assessment of pain at rest and after defecation at postoperative day 1 in both treatment groups using Visual Analogue Scale (Visual Analogue Scale for Pain: ranges from 0 to 10 . Higher scores indicate a worse outcome {greater pain intensity})
Time frame: At day 1 postoperatively
Number of participants requiring rescue analgesia within the first 24 hours postoperatively

Assessment of Pain during rest and after defecation at postoperative day 2,7,14 and 28 in both groups using Visual Analogue Scale (Visual Analogue Scale for Pain: ranges from 0 to 10 . Higher scores indicate a worse outcome {greater pain intensity})
