Study summary

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.

Read the detailed description

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).

Interventions

  • ProcedureMilligan-Morgan Hemorrhoidectomy with Cryotherapy

    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.

What researchers measure

Primary outcomes

  1. 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

Secondary outcomes

  1. Number of participants requiring rescue analgesia within the first 24 hours postoperatively

    Number of participants requiring rescue analgesia within the first 24 hours postoperatively in both groups

    Time frame: within the first 24 hours postoperatively

  2. Pain during rest and after defecation at postoperative day 2,7,14 and 28

    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})

    Time frame: At day 2, day 7, day 14 and day 28 postoperatively

  3. Post operative urine retention

    compare incidence of postoperative urine retention in both groups. (Postoperative urinary retention: inability to void spontaneously after surgery with a bladder volume ≥500 mL on bladder ultrasound).

    Time frame: Within 48 hours postoperatively

  4. Number of participants with surgical site infection

    compare surgical site infection in both groups (surgical site infection: infection at or near a surgical incision within 30 days post-surgery, marked by redness, swelling, or pus.)

    Time frame: Up to 30 days postoperatively

  5. Number of participants with Postoperative bleeding in both groups

    Postoperative Bleeding will be assessed clinically and categorized as mild (self-limited), moderate (requiring medical treatment), or severe (requiring surgical intervention or blood transfusion).

    Time frame: Up to 30 days postoperatively

  6. Hospitalization period

    Compare how many days patients stay in hospital in both groups

    Time frame: From date of hospital admission until date of hospital discharge, assessed up to 10 days after surgery

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Aug 2026; primary completion for Jun 2027, 10 months later.

Of 65 non-industry interventional studies with no phase under Hemorrhoids, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 12 and three quarters within 35. This study's planned 10 months is below that.

Counting every sponsor, half of 70 studies reached it within 23 months; a quarter within 10 and three quarters within 35.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 22, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
