Laparoscopic KTP laser surgery effectively treated endometriosis-related dysmenorrhea and functional dysmenorrhea via vaporization, adhesiolysis, cystectomy, and uterosacral nerve ablation with minimal side effects.

The paper reports laparoscopic laser surgery using a potassium-titanyl-phosphate (KTP) laser emitting green light at 532 nm, applied via small abdominal ports and a 600-micron flexible fiber, in 24 clinically defined endometriosis cases and 9 cases of functional dysmenorrhea. For endometriosis, the authors describe effective treatment across various peritoneal involvements using vaporization, adhesiolysis, and ovarian cystectomy for “chocolate cyst,” with no apparent side effects such as perforation or bladder/ureter/rectum injury. For functional dysmenorrhea, laparoscopic uterosacral nerve ablation (LUNA) produced complete or symptomatic improvement in 7 of 9 cases (77.8%), and the authors attribute failures to insufficient ablation depth in the initial two. This paper is centrally about endometriosis — it evaluates laparoscopic KTP laser surgery (including vaporization, adhesiolysis, and ovarian cystectomy) for endometriosis-related disease and dysmenorrhea.

Abstract

Laparoscopic laser surgery has been performed on 24 cases of clinically defined endometriosis and 9 cases of functional dysmenorrehea, by applying the potassium-titanyl-phosphate (KTP) laser, which radiate a visible green-light laser beam at 532 run as the frequency doubled or second harmonic Eight of Nd: YAG laser of invisible 1064 nm. This laser has no need for an specific aiming beam and is easily applicable with minimum invasion of several small tapping holes into the abdominal cavity by easily delivering through flexible optic fiber of 600 micron in diameter.Clinically, in all cases of various per involvements of endometriosis has been effectively carried out by vaporization, adhesiolysis, and ovarian cystectomy on chocolate cyst, without any apparent side effect of perforation or bladder, ureter and/or rectum. Laparoscopic uterosacral nerve ablation (LUNA) has been performed on 9 cases of so-called functional dysmenorrhea, revealing 7 cases (77.8%) of complete or symptomatic improvements, all of which have been documented as the sufficient depth of ablation, excluding the ineffective initial two cases of minimum and superficial ablations.
