Otogenic brain abscess--a case report.

Brain abscess is one of the life-threatening complications of otitis media. Mortality and morbidity have decreased with the advent of antibiotic therapy. More frequently encountered in cases of acute otitis media in the preantibiotic era, in recent years otogenic brain abscess was noticed almost only in patients of chronic otitis media with cholesteatoma. A case of brain abscess in a 49-year-old female was initially diagnosed as a headache. A high resolution computed tomography (HRCT) scan of the temporal bones later revealed that there were two abscesses over the right side temporal lobe. A modified radical mastoidectomy was performed. Cultures of the middle ear cholesteatoma later grew Pseudomonas aeruginosa and Strenotrophomonas maltophilia. Antibiotic therapy was carried on for three months postoperatively. The patient improved but retained a conductive hearing loss.

Use of intraoperative ultrasonography during hepatolithectomy.

Complete clearance of intrahepatic stones has long been a major surgical challenge. To reduce the incidence of residual stones, we used intraoperative ultrasonography (IOUS) to localize them and guide lithectomy in 38 patients with hepatolithiasis between July 1988 and December 1993. All patients had multiple intrahepatic stones; 24 had accompanying extrahepatic calculi. Hepatic stones were confined to the left intrahepatic biliary tract in 13 patients, to the right in 9, and in both lobes in 16. Twenty-three patients underwent common bile duct exploration followed by T-tube drainage, 8 had transhepatic lithotomy with or without choledocholithotomy, 3 had choledocolithotomy and Roux-en-Y side-to-side choledochojejunostomy, and 2 had hepaticojejunostomy, left lobectomy was performed in the remainder. In 35 patients cholecystectomy was performed at the same time. Complete clearance of the stones was achieved in 36 patients (94.7%). The incidence of retained stone was decreased to 5.3%. No associated complications occurred. IOUS can accurately localize intrahepatic calculi, directly orient lithotomy instruments to approach the stones, demonstrate the spatial relation between stone and intrahepatic critical structure, and thereby choose an optical route for transhepatic lithotomy. Imaging can be repeated at any time with no radiation exposure to the patient or the medical staff.
