Diagnostic laparoscopy.

Diagnostic laparoscopy continues to play an important role in the accurate evaluation of patients with abdominal disorders. Combined with laparoscopic ultrasound, it is highly accurate in the staging of intra-abdominal malignancies, and it is superior to transcutaneous ultrasonography and computed tomography. Other important applications include the evaluation of patients with acute and chronic abdominal pain, acute abdomen, peritonitis, and blunt and penetrating abdominal trauma. Laparoscopy now rests firmly in the hands of surgeons. The majority of last year's papers originated from departments of surgery; papers on laparoscopy in hepatic disorders are sorely missing in this year's review.

Significance of solitary and multiple esophageal ulcers in patients with AIDS.

We endoscopically evaluated odynophagia and/or dysphagia in 23 patients with acquired immunodeficiency syndrome (AIDS). Eleven patients (48%) were found to have esophageal ulcers. Seven of them had deep, sharply demarcated, well-circumscribed ulcer craters with raised edges; in two the ulcer extended to the muscularis propria. Ulcers were single in four patients, multiple in six, and unspecified in one. Biopsies were nondiagnostic. In eight patients, mycobacterial, viral, and fungal cultures were negative. Specific infections diagnosed in three patients were treated with appropriate agents. Ulcers were treated symptomatically, and seven patients received therapy for suspected viral etiology. Symptoms remained unchanged in five patients, improved in three, and resolved in two. Fifty-five percent of patients died within 3.6 months (mean) of diagnosis. Large solitary and multiple esophageal ulcers are common in AIDS patients with odynophagia and dysphagia.

Niacin-induced hepatotoxicity: unusual presentations.

We report four cases of niacin-induced hepatotoxicity. All four patients were using sustained-release niacin preparations. When they stopped taking niacin, symptoms and laboratory abnormalities resolved. Two of the patients had focal fatty infiltration of the liver on imaging studies, a presentation of niacin hepatotoxicity not previously described. One patient had a coagulopathy even though aminotransferase levels were only mildly elevated. We recommend that patients using sustained-release preparations of niacin have periodic monitoring of liver enzymes and that the preparation be discontinued if any abnormalities develop.

Endoscopic diagnosis and treatment of esophageal cancer.

Esophageal carcinoma is one of the deadliest malignant tumors. This article reviews its epidemiology, etiology, and clinical and endoscopic presentation, as well as methods for proper staging to identify the patients who will not benefit from surgery and require palliative therapy. The various treatment options are discussed in detail with an emphasis on the latest endoscopic palliative measures.

Non 0-1 Vibrio cholerae septicemia and culture negative neutrocytic ascites in a patient with chronic liver disease.

Non 0-1 Vibrio cholerae infection is often associated with ingestion of contaminated seafood and its common presentation is gastroenteritis. Septicemia may be found in immunocompromised hosts resulting in mortality approaching 50%. A case is reported of non 0-1 Vibrio cholerae infection presenting with septicemia in a patient with neutrocytic ascites suggestive of spontaneous bacterial peritonitis.

Endoscopic orientation within the duodenal bulb.

Laparotomy performed for bleeding duodenal ulcer after diagnostic/therapeutic endoscopy revealed a disparity in location of the lesion on several occasions at our institution. The position of the duodenal lesion is important in assessing bleeding potential. Twenty consecutive patients underwent upper gastrointestinal endoscopy by a staff and trainee gastroenterologist to evaluate the ability to determine the true posterior position of the duodenal bulb. Documentation of the posterior bulb location was verified by pooled colored fluid with the patient in a supine position. True posterior location was chosen only 30% of the time by an experienced gastroenterologist. This observation may have clinical implications in assessing the patient's bleeding potential and in the use of coaptive coagulation for control of ulcer bleeding.
