Laparoscopic dissection with a monopolar, low-energy, high-frequency needle electrode:: Indications and complications

Objective: The monopolar, low-energy, high-frequency needle electrode is an innovative tool for electrosurgical dissection at laparoscopy. We reviewed the use of the needle and complications. Methods: A total of 1384 patients underwent laparoscopic operations including the new monopolar needle between 1990 and 1998. We reviewed indications for surgery, the intraoperative and postoperative course, indications for use of the needle, and complications. Results: The monopolar needle electrode was used for a wide range of indications, most commonly adhesiolysis (38.5%) and ovarian cystectomy (13%). Four patients developed superficial skin lesions, which were probably a result of patient positioning. Four patients with extensive adhesiolysis involving bowel developed bowel lesions. One patient developed postoperative bleeding after adnexectomy. Conclusion: The monopolar, low-energy, high-frequency needle electrode is a safe dissecting tool for laparoscopic surgery and has a wide range of indications.
