Abstract
We reported a case to perform laparoscopic fenestration of a large symptomatic liver cyst using two newly deviced microwave scalpels (blade type and round type electrode).
A 51-year-old female was admitted to our hospital with a chief complaint of upper abdominal fullness on April 4, 1993. Ultrasound examination and computed tomography of the abdomen revealed a large liver cyst of the left lateral segment and its protrusion fromliver surface. We decided to resect the dome of the liver cyst by laparoscopic means. The liver cyst was punctured and the contents, brown fluid evacuated. After incision of the collapsed cyst wall the cyst membrane was widely excised with blade type microwave electrode. And the internal surface of the cyst was coagulated with round type microwave electrode. The patient recovered well and discharged home on the 7th postoperative day. Three months later, she was still asymptmatic and showed small low density area of the lateral segment of the liver by abdominal CT examination. Laparoscopic fenestration of the liver cyst and coagulation of its internal surface using microwave coagurator was a new useful surgical procedure.
