A new surgical device, the EEA 34-mm circular stapler, simplifies stapled mucosectomy for hemorrhoids and prolapse. While effective, further improvements are needed to reduce recurrence rates in all patient cases.

Area of Science:

  • Colorectal Surgery
  • Surgical Devices
  • Gastroenterology

Background:

  • Stapled mucosectomy is a common procedure for hemorrhoids and rectal prolapse.
  • Challenges exist in deep gluteal clefts and narrow ischial distances, hindering PPH dilator insertion.
  • The EEA 34-mm circular stapler offers a potential solution for these anatomical difficulties.

Purpose of the Study:

  • To evaluate the efficacy and safety of the EEA 34-mm circular stapler in stapled mucosectomy.
  • To assess the performance of the ASA Kit in facilitating the procedure.
  • To determine complication and recurrence rates associated with this technique.

Main Methods:

  • Eighty-five patients with third/fourth-degree hemorrhoids or mucosal prolapse underwent stapled mucosectomy using the EEA 34-mm circular stapler.

  • The procedure utilized the ASA Kit, including a circular anal dilator and surgical anoscope.
  • Data on operative time, bleeding, complications, and follow-up outcomes were collected across four centers.

    • Main Results:

    • The mean operative time was 16 minutes, with a mean excised mucosal band width of 4.7 cm.
    • Postoperative complications included bleeding (11.7%), perianal hematomas (3.5%), and stapled suture strictures (2.3%).
    • Excellent or good anopexy was achieved in 88.2% of patients, with recurrence rates of 17.6% (small prolapses) and 2.3% (full prolapses).

    Conclusions:

    • The EEA 34-mm circular stapler, facilitated by the ASA Kit, simplifies stapled mucosectomy, especially in challenging anatomies.
    • While generally safe and effective, improvements in circular stapler design are necessary to optimize treatment for all prolapse sizes and minimize recurrence.
    • Further research may focus on refining stapler technology to enhance long-term outcomes in hemorrhoidal and prolapse surgery.
