The laparoscopic aspects were classified as red, black and white lesions. The histological perimeters used were presence of hemosiderin, vascularization of the stroma, occurrence of mitosis, presence of debris, fibrotic tissue, depth of the lesion and functional characteristics of glands and stroma. There was a statistically significant association with stroma vascularization, intraluminal debris, fibrotic tissue, depth os the lesion and functional characteristics of the glands and stroma with each of the three types of lesions. There was no significant statistical association between presence of hemosiderin and mitosis in red, black and white lesions. The findings showed an agreement regarding the evolution theory from red to black and finally to white lesions in peritoneal endometriosis.
Progression also occurs with depth.
Red lesions are superficial and as the progression occurs to black and white lesions, the depth increases. F. H. Loh presented Ovarian Follicular Response After Laparoscopic Cystectomy for Endometrial Ovarian Cysts . Dr. Loh pointed out that endometriotic cysts are some of the more common pathologies encountered during laparoscopic ovarian cystectomy. One hundred and eighty eight laparoscopic ovarian cystectomies were performed for endometriotic cysts. For women above the age of 35 years, there was no difference between the responses of post-cystectomy ovaries and normal ovaries in all of the different stimulation cycles.
