[Non-functional renal paraganglioma associated with carotid paraganglioma and appendicular mucocele].

OBJECTIVE: A case of nonfunctional renal paraganglioma associated with appendicular mucocele and metachronic carotid paraganglioma is presented. METHODS/RESULTS: A 68-year-old patient consulted for abdominal pain. Patient evaluation with US, CT and opague enema showed an elongated mass that compromised the cecum and a solid mass in the right kidney. The patient underwent appendectomy and radical right nephrectomy. The anatomopathological findings showed an appendicular mucocele and renal paraganglioma. The postoperative hormone analyses were normal. A carotid paraganglioma was removed 8 months later. CONCLUSIONS: Renal tumors arising from neural crest cells are uncommon. To our knowledge, this is the third case of nonfunctional renal paraganglioma reported in the literature. The associated appendicular mucocele was an incidental finding.

[Perioperative transfusion in prostatic surgery].

OBJECTIVE: To analyze the likelihood of perioperative transfusion in prostate surgery. METHODS: The records of patients who underwent prostate surgery at the Hospital Central de Asturias en 1996 were reviewed. The abstracted patient discharge records, encoded according to the ICD-9-CM, were analyzed for gender, age, diagnosis, surgical and non-surgical procedures, including transfusions of blood products. RESULTS: 29 (14.2%) of 204 operated patients required transfusion. By univariate analysis, the likelihood of requiring transfusion was significantly higher in patients with cancer (28.8%), patients undergoing radical prostatectomy (40%), and those undergoing more than one surgical procedure (21.2%). By multivariate logistic regression analysis, the surgical procedure, age and simultaneous urinary bladder surgery were related with the likelihood of requiring transfusion. The adjusted odds ratio for perioperative transfusion was 10.14 times in radical prostatectomy than in transurethral prostatectomy, 2.67 times for patients more than 75 years than in those aged less, and 2.85 times in patients undergoing simultaneous urinary bladder surgery than those who do not. CONCLUSIONS: Due to the wide range of variability of the adjusted likelihood for transfusion in prostate surgery (3.5% to 83.4%), estimation of the individual likelihood for transfusion could be useful for planning surgical transfusions, pretransfusion tests and autologous transfusion in these patients.

[Biliary lithiasis].

We have reviewed our experience with 2,430 cases of lithiasis of the biliary tract, 500 of them located in the common bile duct and 104 corresponding to residual lithiasis. We have made a general reflexion on the problems aroused by this very common al condition, which has an imprevisible, some times severe, outcome. The recent acquisition of new conservative methods, as disolvents and lithotrix, and the diagnostic and therapeutic role of endoscopy have revolutionated the state of the art and have introduced controversial points still unsolved. As it is common in clinical practice, biliary lithiasis should be approached in a multidisciplinary fashion, employing the most convenient diagnostic procedure for the clinical situation of the patient; a priori no accredited procedure should be disregarded.
