ABSTRACT

Introduction: Mucinous cystadenoma of the appendix is a rare condition that occurs from the storing of mucin in appendix. We describe a case of successful treatment by laparoscopic resection done very simply without rupture by using linear staple. This patient was discharged after five postoperative days without event. We tried to do non-touch operation with linear stapler. We strongly suggest this technique should become more popular around the world.

Case Report: A 70-year-old woman was referred to our hospital with appendiceal swelling which was incidentally discovered by CT scan. CT scan indicated 4 cm in-sized vermiform mass arising from cecum with hypodense cystic structure and calcification on edge without any malignant features. Under preoperative diagnosis of benign tumor, we performed laparoscopic appendectomy safely and rapidly with an endoscopic linear stapler. Depending on the surgical pathology, we made sure the stump was negative and there was no malignancy. The final pathological diagnosis also was mucinous cystadenoma of the appendix. This patient was discharged after five postoperative days without any event.

Conclusion: We recommend doing two step-operation for avoiding complications and to do minimum invasive surgery for this type of benign-like mucinous cystadenoma. In this case, we succeeded in non-touch operation with linear stapler.
