Histologic analysis of laparoscopic diagnosis of endometriosis

[Objective] To estimate the accuratissime of laparoscopic diagnosis to endometriosis of different pelvic focus of infection. [Methods] A study of 85 patients with diagnosis of endometriosis laparoscopically were excised and examined pathologically. Pathologic diagnosis was taken as the standard, positive predictive value (PPV) was calculated in different type of endometriosis with laparoscopic diagnosis. [Results] 55 patients in 85 had ovarian endometriotic cysts. Totally, 148 peritoneal endometriotic lesions, 69 ovarian endometriotic cysts were obtained. Black focus of infection was the most common in cavitas pelvis endometriosis (32.5% 70/217), next adenoma endometrioides ovarii cystis (31.8% 69/217). The PPV was 70% versus histologic diagnosis of peritoneal endometriosis. Lesions in black or adenoma endometrioides ovarii cystis were confirmed histologically in 94.2% and 84.7% respectively. [Conclusions] Laparoscopic diagnosis of cavitas pelvis endometriosis are not more likely to be histological confirmed, but laparoscopic diagnosis in black or adenoma endometrioides ovarii cystis consistent with pathologic diagnosis is to be trusted.
