The morphological evaluation of ipsilateral and contralateral vasa deferentia in a rat model of unilateral spermatic cord torsion

Aim Spermatic cord torsion is a surgical emergency that requires early intervention to protect the effected testicle. The literature review about this ischemic reperfusion (I/R) injury reveals not only ipsilateral, but also contralateral testicular and epididymal injuries in a broad fashion. However, there is no data about vas deferens injury related with this surgical emergency. The aim of the study is to evaluate the morphological changes of the vas deferens due to testicular I/R injury. Materials and methods Eighteen Wistar-Albino rats were allocated to three groups. Bilateral vasa deferentia of control group (Gr C, n = 6) were harvested without any surgical intervention. The torsion group was subjected to 2 h torsion and 2 h detorsion of the left testicle (Gr T, n = 6) and the third group underwent sham operations (Gr S, n = 6). Bilateral vasa deferentia of Gr T and S were harvested after surgery. The either side of the vas deferens was divided into three equal segments and these regions (adjacent to urinary bladder, medial and adjacent to testicle) were evaluated histopathologically. Results The electron microscopic evaluation of bilateral vasa deferentia of Gr T revealed different degrees of degeneration on either side. The region adjacent to testicle of the contralateral vas deferens was the most effected segment when compared with the other segments. Conclusion In the light of these findings, it can be said that testicular I/R injury effects not only testis and epididymis, but also the adjacent vas deferens. This effect seems to be bilateral, like the testis and epididymis injury. Moreover, it mostly seems to depend on the apoptotic processes

Sponge in the belly: postoperative imaging findings of oxidised cellulose (Surgicel®)

Aim: Surgicel (R) is an absorbable material for local haemostasis. Its existence at surgical sites is troublesome since it interferes with the radiological images of postoperative complications. The aim of this study is to demonstrate the postoperative appearances of intraabdominal Surgicel. Materials and methods: Twelve guinea pigs were allocated to 2 groups. Animals with intraperitoneal (n = 6) and retroperitoneal (n = 6) Surgicel pieces were scanned postoperatively. Results: The density and intensity of Surgicel were compared with adjacent tissues. All retroperitoneal haemostats were hypointense compared to tissues next to them in T1W images but hyperintense compared to muscles, and 5 were hyperintense compared to the liver and hypointense compared to fat and the renal cortex in T2W images. All intraperitoneal haemostats were hypointense compared to the liver, fat, and renal cortex in T1W but hyperintense compared to muscles, the liver, and the renal cortex in T2W images. On CT scans, all retroperitoneal haemostats were hyperdense compared to fat tissue and 4 were hypodense compared to liver and muscles. All intraperitoneal haemostats were hypodense compared to muscles and the liver while 5 were isodense compared to fat and hypodense to the renal cortex. Conclusion: Surgicel located intraabdominally could appear radiologically distinct. Considering the surgical site and anatomical spaces of Surgicel could help clinicians to evaluate the situation
