RESUMO
Bowel vaginoplasty is a well-described procedure utilizing a pedicled segment of large or small bowel. It has most commonly been used for vaginal agenesis, male-to-female gender affirmation surgery when the phallus skin is not sufficient, or a revision after failure of the primary reconstruction. Our case report describes the usage of a pedicled segment of large bowel to reconstruct the vagina after severe stricture of the original reconstruction. We were able to provide relief of the symptomatic Hartmann's pouch mucocele, urethral stricture, and provide a functional introitus and vaginal canal. This technique can provide a framework that can be used as a salvage plan in patients with previously irritated and inhospitable defects.
RESUMO
Gallbladder torsion or volvulus is a rare but potentially lethal entity. We report the imaging findings of gallbladder torsion and describe a potentially novel ultrasound sign for the preoperative diagnosis of torsion. An 87-year-old woman presented with a 4-day history of right upper quadrant pain. An initial right upper quadrant ultrasound exam demonstrated cholelithiasis and findings of acute cholecystitis which included gallbladder distension, wall thickening, trace pericholecystic fluid, and a positive sonographic Murphy's sign. Gallbladder torsion was prospectively diagnosed on the subsequent contrast-enhanced CT scan of the abdomen based upon the abnormal transverse orientation of the gallbladder with the neck directed laterally. Ultrasound images were reviewed and a "knot"-like hyperechoic nodular appearance of the torsed cystic duct close to the gallbladder neck was clearly apparent. Prospective identification of the torsed cystic duct may prompt the ultrasound diagnosis of gallbladder torsion.
