Appendiceal mucocele. Contraindication to laparoscopic appendectomy

Summary

Laparoscopic appendectomy for mucinous tumors poses a risk of cancer spread. Surgeons should consider open surgery for suspected appendiceal tumors to prevent peritoneal carcinomatosis.

Area of Science:

  • Gastroenterology
  • Surgical Oncology
  • Minimally Invasive Surgery

Background:

  • Laparoscopic appendectomy is a common procedure for acute appendicitis.
  • Refining indications for laparoscopic surgery is ongoing.
  • Appendiceal mucinous tumors present unique surgical challenges.

Observation:

  • A case study involved laparoscopic resection of an appendiceal mucocele.
  • The mucocele was caused by a nonperforated mucinous adenocarcinoma.
  • Diffuse peritoneal carcinomatosis was observed 9 months post-laparoscopy.

Findings:

  • Laparoscopic resection of appendiceal mucinous tumors can lead to widespread peritoneal implantation.
  • This is the first reported case of laparoscopic appendiceal mucinous tumor resection associated with diffuse peritoneal carcinomatosis.

  • Even benign-appearing adenomas can cause peritoneal spread.

    • Implications:

    • Consider conversion to open appendectomy when an appendiceal mucinous tumor is suspected during laparoscopy.
    • Atraumatic technique is crucial if laparoscopic resection is pursued for appendiceal tumors.
    • This case highlights the risk of cancer dissemination with laparoscopic resection of malignancy.
