Transanal excision of rectal carcinoma

Area of Science:

• Colorectal Surgery
• Surgical Oncology
• Gastroenterology

Background:

• Rectal carcinoma presents with varied symptoms, including bleeding and changes in bowel habits.
• Early detection through screening proctosigmoidoscopy identifies asymptomatic cases.
• Tumor characteristics like size and histology influence treatment decisions.

Purpose of the Study:

• To evaluate the efficacy and safety of transanal excision for rectal carcinoma.
• To assess patient outcomes, including survival and local recurrence rates.
• To determine the suitability of transanal excision for specific patient profiles.

Main Methods:

• Retrospective analysis of 38 patients with rectal carcinoma treated by transanal excision.
• Data collection on patient demographics, tumor characteristics, and presenting symptoms.
• Evaluation of postoperative outcomes, complications, and long-term follow-up.

Main Results:

• The study included 38 patients (22 men, 16 women) with a mean age of 67 years.
• Tumor types included adenocarcinoma (92%), squamous cell carcinoma (4%), and cloacogenic carcinoma (4%).
• Operative mortality was 3%, morbidity 7%, with good postoperative hospitalization and successful management of recurrences.

Conclusions:

• Transanal excision is a safe and effective treatment option for carefully selected rectal carcinoma patients.
• The procedure demonstrates favorable overall survival and local control rates.
• Further research may refine patient selection criteria for optimal outcomes.
