Simultaneous pancreas-kidney transplantation: infectious complications and microbiological aspects.

OBJECTIVE: The purpose of this study was to describe the clinical and microbiological characteristics of the infectious complications among simultaneous pancreas-kidney transplantations (SPKT). MATERIALS AND METHODS: Among the first 45 SPKT the mean age was 34 years (range, 21 to 49) and the mean duration of follow-up 13 months (range, 2 to 27 months). RESULTS: Twenty-three patients (51%) presented at least one to three episodes (1.7 mean) of infectious complications that needed hospitalization. The etiology of the infections included 71% bacterial (44% gram-negative rods and 27% gram-positive cocci), 16% viral (12% from CMV and 4% from Herpes sp) and 13% fungal (8% by Candida sp and 4% by others fungus). Wound and urinary infections were most frequent, occurring in 22% and 28% of the patients, respectively. All patients who were submitted to vesical drainage developed infections in contrast a rate of only 44% among patients undergoing enteric drainage. CONCLUSION: Infectious complications are the main cause of morbidity and mortality following simultaneous pancreas-kidney transplantation, especially with vesical drainage. The use of enteric drainage combined with administration of broad spectrum prophylactic antibiotics is recommended.

Magnetic resonance cholangiography in the diagnosis of biliary complications after orthotopic liver transplantation.

OBJECTIVE: The aim of our study was to evaluate the role of magnetic resonance cholangiography (MRC) in the diagnosis of biliary tract complications (BC) after orthotopic liver transplantation (OLT). MATERIALS AND METHODS: Among 21 OLT patients who underwent routine follow-up MRC using a breath-hold T2-weighted turbo spin-echo sequence with half-Fourier acquisition (HASTE), 5 had an elevated serum alkaline phosphatase level. Diagnostic confirmation was obtained with endoscopic retrograde cholangiography (ERC) (n = 11), surgery (n = 3), or clinical and laboratory follow-up of at least 1 year (n = 8). RESULTS: In 13 patients, no abnormality of the biliary tract was detected using MRC. In 8 patients, anastomotic strictures were diagnosed, 7 of which were confirmed at surgery or using ERC. One patient with normal findings at MRC and abnormal liver function test results was found to have a stricture at ERC. All patients with normal MRC and liver function tests had 1 year of uneventful follow-up and were considered true-negative cases. We found that MRC had 87.5% sensitivity, 92.3% specificity, 87.5% positive predictive value, 92.3% negative predictive value, and 90.4% accuracy for the diagnosis of BC. CONCLUSION: MRC is a valuable examination to detect BC after OLT. It provides useful information for planning interventional procedures.

Laparoscopic cholecystectomy in a patient with a duplicated cystic duct.

Cystic duct duplication with a single gallbladder is one of the most uncommon abnormalities of the biliary tract, with fewer than 15 instances published. The authors describe a 49-year-old patient undergoing a laparoscopic cholecystectomy in whom a second cystic duct was found, initially misdiagnosed as the biliary tract. The cholecystectomy was performed successfully with the aid of intraoperative cholangiography. It is the first time a duplicated cystic duct has been treated successfully using a laparoscopic approach.

[Hepatocellular carcinoma: treatment of 23 cases].

In this study, we compared the clinical aspects of the patients with hepatocarcinoma treated in the Clinical and Surgical Gastroenterology Division, Federal University of São Paulo Medical School. Thirty three patients with hepatocarcinoma were treated between 1989 and 1997, 23 were treated surgically or by chemotherapy. Ten of them, in bad clinical conditions, were treated only with supportive treatment. Among the 23 treated patients, 12 were treated surgically, 10 with transcatheter arterial chemoembolization and one with systemic chemotherapy. The liver nodes size varied from 2.6 to 20 cm, being 82% greater than 5 cm. The mean survival was 14.8 months for the surgical treated patients and 9.8 months for the transcatheter arterial chemoembolization treated patients. These differences were not significant by the Kaplan-Meyer curve. The patients with liver nodes under 5 cm had better survival (P < 0.05). We can conclude that independent of the clinical stage, the size of the liver node is an important factor on prognosis. Patients with live nodes smaller than 5 cm have better survival than the others with greater tumors.

[Alkaline reflux gastritis. Surgical treatment].

The authors present the results of 35 patients with alcaline gastritis submitted to truncal vagotomy and jejunostomy by Roux in technic. Preoperative diagnosis was founded in clinical symptoms and endoscopy with histopathology. In a follow-up of 84,8% of the patients, clinical results were excellent or good in 92,8%, showing relief of pain and vomits, gastric endoscopy almost normal and on histopathology.

[Solid cystic tumor of the pancreas. Case report].

The solid and cystic tumour of the pancreas is a rare entity that occurs in young women. Clinically the patients are often asymptomatic, the tumor of variable size (2-10 cm) and show a fibrous encapsulation. In contrast to adenocarcinoma of pancreatic ductal cells, which is the most frequent tumor of the pancreas, this tumour have a slow growth, usually do not have metastases and have a favourable prognosis. The authors related the case and have done a revision of the illness.
