[A Case of Sigmoid Colon Cancer with Rectal Intussusception Treated by Robotic Surgery]

Area of Science:

• Gastroenterology
• Surgical Oncology
• Colorectal Surgery

Background:

• Rectal intussusception is a rare condition, often associated with underlying pathology.
• Sigmoid colon cancer can present with unusual symptoms, including anal prolapse.

Purpose of the Study:

• To report a unique case of sigmoid colon cancer presenting as rectal intussusception.
• To describe the successful surgical management of this complex presentation.

Main Methods:

• A case report of an 82-year-old female patient.
• Diagnosis confirmed through clinical examination and subsequent histopathology.
• Surgical treatment involved robotic sigmoidectomy with D3 lymph node dissection.

Main Results:

• The patient presented with anal prolapse, diagnosed as sigmoid colon cancer with rectal intussusception.
• Histopathology revealed double sigmoid colon cancers without ischemic changes.
• The patient experienced no recurrence 16 months post-operation.

Conclusions:

• Sigmoid colon cancer can manifest as rectal intussusception, necessitating prompt surgical evaluation.
• Robotic sigmoidectomy with D3 lymph node dissection is an effective treatment for this condition.
• Early diagnosis and surgical management are crucial for favorable outcomes in complex colorectal cancer cases.
