Summary

Excisional laser surgery effectively treated 62 patients with superficial anal neoplasms, achieving high clearance rates and no significant complications. This laser technique offers a suitable outpatient option for perianal and anal canal tumor removal.

Area of Science:

  • Oncology
  • Surgical Technology
  • Dermatology

Background:

  • Perianal, perineal, and anal canal neoplasms require effective treatment options.
  • Excisional laser surgery presents a minimally invasive approach for tumor removal.

Purpose of the Study:

  • To evaluate the efficacy and safety of excisional laser surgery for various anal canal neoplasms.
  • To assess oncological outcomes and complication rates associated with this surgical technique.

Main Methods:

  • Excisional laser surgery performed under local anesthesia with an operating microscope.
  • Outpatient treatment for 62 patients with benign epithelial/pigmented tumors, carcinoma in situ, and invasive squamous cell carcinoma.
  • Assessment of resection margins, recurrence rates, and local complications.

Main Results:

  • 95% of patients achieved clear resection margins after primary laser surgery; 3 required secondary excision.
  • Recurrence or new disease occurred in 5 patients with carcinoma in situ, successfully managed with re-excision.
  • No significant local complications were observed post-surgery, with all patients disease-free at follow-up (median 25 months).

Conclusions:

  • Excisional laser surgery is a suitable and effective method for treating superficial perianal, perineal, and anal canal neoplasms.
  • The technique offers high clearance rates, minimal complications, and good long-term outcomes in an outpatient setting.
  • Laser surgery provides a viable alternative for managing these specific types of tumors.
