Laparoscopic appendectomy for appendiceal intussusception assisted by colonoscopy: A case report.

Area of Science:

• Gastroenterology
• Surgical Oncology
• Minimally Invasive Surgery

Background:

• Appendiceal intussusception can be caused by appendiceal cancer.
• Ileocecal resection is often preferred over appendectomy due to the risk of tumor cell dissemination.
• Current treatment challenges include safely resecting the appendix without spreading cancer cells.

Purpose of the Study:

• To describe a new combined laparoscopic and colonoscopic technique for appendiceal intussusception.
• To demonstrate an oncologically safe method for appendix resection.
• To present an alternative to ileocecal resection when malignancy is not suspected.

Main Methods:

• A 40-year-old male with appendiceal intussusception underwent a combined laparoscopic and colonoscopic procedure.
• Resection was performed within the cecal lumen to prevent peritoneal dissemination.
• Histopathology confirmed chronic inflammation without malignancy.

Main Results:

• The combined technique successfully resected the appendix while preventing tumor cell spread.
• The patient experienced an uneventful postoperative recovery.
• Histological examination ruled out malignancy.

Conclusions:

• Simultaneous laparoscopy and intraoperative colonoscopy are feasible for appendiceal intussusception.
• This technique offers an oncologically sound alternative to ileocecal resection when malignancy is not suspected.
• It avoids unnecessary extensive surgery and lymph node dissection.
