Assessment of surgical resectability of pancreatic adenocarcinomas with multidetector computed tomography: what are the possibilities and problems?

Background/aims: To investigate the accuracy of multidetector computed tomography (MDCT) in preoperatively determining the surgical resectability of pancreatic adenocarcinomas.

Materials And Methods: Multidetector computed tomography, surgery, and pathological results of 274 patients with pancreatic adenocarcinoma were evaluated retrospectively. MDCT findings were compared with surgical and pathological findings to determine the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of MDCT in determining surgical resectability.

Effect of conditioning on visceral organs during indirect ischemia/reperfusion injury.

Background: The mortality and morbidity rates of even extensive thoracoabdominal replacement have improved markedly in recent years. We investigated the effects of a temporary occlusion of the aorta as a direct precondition and temporary occlusion of the axillary artery for remote preconditioning to determine any effects that preconditioning may have on indirect (nonischemic) injuries to visceral organs (indirect effects of remote ischemia/reperfusion injury).

Methods: Thirty-seven New Zealand white rabbits were divided into five groups: controls (sham-operated; group 1); direct ischemia to the infrarenal aorta without preconditioning (group 2); direct ischemic preconditioning to the infrarenal aorta (group 3); remote ischemic preconditioning before clamping the infrarenal aorta (group 4); and simultaneous direct aortic and remote ischemic preconditioning before the clamping and during clamping of the infrarenal aorta (group 5).

Giant anorectal condyloma acuminatum of buschke-lowenstein: successful plastic reconstruction with bilateral gluteal musculocutaneous v-y advancement flap.

A 58-year-old male patient presented with an anorectal verrucous carcinoma, also known as Buschke-Lowenstein tumor. Clinically, the lesion of the patient best resembled giant condyloma acuminatum with a cauliflower-like appearance. The diagnosis was confirmed with biopsy and an abdominoperineal resection was performed.

Giant hemorrhagic adrenal pseudocyst in a primiparous pregnancy: report of a case.

Adrenal cysts are rare and are usually discovered incidentally during diagnostic imaging, surgery, or autopsy. Most cystic lesions of the adrenal gland are nonfunctioning and become symptomatic when complicated by rupture, hemorrhage, or infection. A 40-year-old woman presented with a history of gradual-onset pain in her left flank region at 20 weeks' gestation.
