Brief Summary

Cap-assisted endoscopic sclerotherapy (CAES) is a new interventional therapy for internal hemorrhoids and rectal prolapse under colonoscopy. However, the long-term efficacy and safety of CAES in the treatment of internal hemorrhoids and rectal prolapse are still not clear due to the lack of large sample studies. Therefore, a nationwide multi-center, large sample, prospective and cohort study was designed to evaluate the efficacy and safety of CAES in the treatment of internal hemorrhoids and rectal prolapse, to provide reliable evidence for popularization of this minimally invasive technology.

Outcome Measures

Primary Outcomes (1)

  • Recurrence rate

    Recurrence rate defined as the proportion of patients with recurrent hemorrhoids at 24 weeks post-CAES, as derived from patients' self-reported answer. Patients will be considered to have recurrent hemorrhoids when any of the following are recorded: (1) "Unchanged or worse compared with before starting treatment" at 24th week as reported by the patient, or (2) seeking repeat CAES treatment, alternative non-surgical/surgical treatments for internal hemorrhoids within 24weeks (except medication treatment), or (3) presence of any symptoms or events that strongly indicated recurrent hemorrhoids among patients not meeting (1) or (2).

    1st week to 24th week

Secondary Outcomes (7)

  • Improvement rate

    1st day, 1st week, 2nd week and 24th week

  • Failure rate

    1st day, 1st week, 2nd week and 24th week

  • Three-level EuroQol five dimensions (ED-5Q) health scale scores

    24th week

  • Adverse events (AEs)

    1st day, 1st week, 2nd week and 24th week

  • severe adverse events (SAEs) severe adverse events (SAEs) severe adverse events (SAEs) Severe adverse events (SAEs)

    1st day, 1st week, 2nd week and 24th week

  • +2 more secondary outcomes
