When one of my patients opts for an obliterative procedure, I almost always choose to perform a colpectomy.
The presence of subepithelial fibrosis is not a diagnostic discriminator but in general, this is mild in degree in asthmatic airways as opposed to the definite constrictive and/or proliferative/polypoid obliterative bronchiolitis of IBD.
DISCUSSION: Fournier's Gangrene is a relatively uncommon infection usually beginning with insidious onset of pruritus and discomfort of the external genitalia, perineal and perianal regions and characterized by widespread fascial necrosis with relative sparing of skin and underlying muscle leading to obliterative endarteritis resulting in gangrene [12,13] The disease is classified as type-1 when caused by a mixture of aerobic and anaerobic microorganisms and type-2 when caused by group A streptococcus alone or synergistic with a second organisms (s, aureus, coliforms, bacteroides spp).
Note the presence of obliterative bronchiolitis in a case of pleuroparenchymal fibroelastosis associated with bone marrow transplantation (hematoxylin-eosin, original magnification x200).
For that reason, he advised against performing vaginal hysterectomy at the time of colpocleisis; patients who can tolerate that should be undergoing reconstructive surgery, not an obliterative procedure, he said.
This is in contrast to the electrical and laser techniques, in which intense local heat destroys tissue by desiccating and charring it and produces hemostasis by obliterative coagulation.
Fetal disease is confirmed by extensive avascular villi, obliterative endarteritis, hemarragic endovasculitis vascular thrombi.
Worsey et al concluded that unilateral exploration in primary hyperparathyroidism is safe and cost-effective and avoids obliterative scarring of the contralateral neck.
1-3) Obliterative (constrictive) bronchiolitis, the histopathologic substrate of BOS, is rarely identified on conventional biopsies, at least in part owing to the relative paucity of small airways and sampling bias.
EHBA is an obliterative cholangiopathy of unknown cause affecting both the intra- and extrahepatic bile ducts.
In constrictive or obliterative bronchiolitis the airway has luminal narrowing due to subepithelial scarring (ie, between epithelium and smooth muscle cells, which are absent in the ex vivo contraction artifact).
