[Diagnostic role of ultrasound in the transplanted kidney].

Among diagnostic postoperative procedures in renal cadaver transplantation echographic examination shows high sensitivity and specificity (over 80%). Urographic examination is in fact often dangerous and impossible in non-functioning grafts. Echography can reveal several liquid and solid collections such as hematomas, urinomas, abscesses, lymphatic collections and so on. Urinary obstructions caused by ureteral clots, calculi, external masses can be also detected through echographic examination. Vascular complications can be evaluated through echo and US Doppler examination showing arterial and venous complications. In most of cases acute and chronic graft rejection can be revealed through echo examination whereas in few cases diagnosis can be made only with the help of renal biopsy, laboratory findings and clinical conditions. In conclusion echography is a safe and reliable procedure in renal graft postoperative monitoring.

Glucose tolerance after portacaval shunt in liver cirrhosis.

The liver plays a key role in glucose homeostasis and insulin metabolism. Altered glucose and insulin levels in peripheral blood are common findings in chronic liver disease. The aim of the present study was to investigate the effect of surgical portosystemic shunt on plasma glucose and insulin responses to glucose administration in a group of cirrhotic patients. For this purpose 10 cirrhotic subjects (8 males and 2 females) aged 42 to 65 years underwent an oral glucose tolerance test (OGTT, 75 g), and an intravenous glucose tolerance test (IVGTT, 0.33 g/kg) before and after undergoing a side-to side portocaval anastomosis (PCS). 6 noncirrhotic, nondiabetic patients matched for sex, age and body weight who underwent abdominal vascular surgery served as controls. In cirrhotic subjects, the PCS resulted in: increased plasma glucose and insulin levels during OGTT; decreased C-peptide level during OGTT; unmodified plasma glucose and insulin concentrations during IVGTT. In control subjects the abdominal surgery did not affect plasma glucose and insulin responses to oral or intravenous glucose loads. These results suggest that in cirrhotic subjects surgical portocaval shunt results in: deterioration of oral but not intravenous glucose tolerance, due to an escape of ingested glucose from the liver; increased peripheral insulin response to oral glucose administration as a consequence of reduction in hepatic removal of the hormone; and decreased pancreatic response to oral glucose due possibly to a greater feed back inhibition of beta-cell. These events seem to be a consequence of the shunt per se and not of a deterioration of hepatocellular function.

[Carbohydrate antigen 19-9 (CA 19-9) and carcinoembryonic antigen in gastrointestinal neoplasms. Comparison of markers].

CA 19-9, a new antigenic tumor marker for gastrointestinal tumors, has been assayed with Carcinoembriogenic antigen, in 90 healthy patients and 47 patients with gastric cancer (20) and colorectal cancer (27). A good specificity has been found for this antigen (97.7%). Its sensibility seems to be slightly superior to that of CEA. However the sensibility for tumors at Mo stage (38%) is indeed scarcely, on the contrary it clearly elevated for tumors at advanced stage (M1)(76%).

Percutaneous renal artery embolization of nonfunctioning allograft: preliminary experience.

Percutaneous renal artery embolization has been introduced as an alternative to nephrectomy for patients with a nonfunctioning allograft and Graft Intolerance Syndrome. The symptoms resulting from this syndrome include fever, local pain, hypertension, and hematuria. From April 2003 to October 2003, 5 patients were treated with this technique. The intraparenchymal renal arteries were embolized by injection of calibrated tris-acryl gelatin microspheres of increasing size (from 100-330 to 700-900 microm) and completed with the insertion of 5-mm-8-mm steel coils in the renal artery. The procedure was well tolerated in all cases; no major complications occurred. In 3 patients, the symptoms disappeared immediately. In 1 patient, it was necessary to perform a second embolization due to collateral circulation developing from a lumbar artery; this further procedure resolved the symptoms. In the last case, the patient underwent nephrectomy because of septic fever. In conclusion, patients with this syndrome refractory to medical treatment may be treated by the effective and minimally invasive procedures of percutaneous allograft artery embolization with no significant short-term or late complications.

Kidney transplantation from elderly donors: a prospective randomized study comparing celsior and UW solutions.

AIM: The aim of present study was to assess the effect of Celsior as compared with University of Wisconsin (UW) solution on immediate and long-term function of kidney transplants harvested from elderly donors. METHODS: A prospective multicenter randomized study was designed to evaluate the efficacy of Celsior versus UW solution for the clinical preservation of the kidney. Fifty renal transplants were performed from donors over 60 years old. Twenty-five kidneys were stored in Celsior and 25 in UW solution. The groups were comparable with regard to donor and recipient characteristics. Renal function outcomes were compared by evaluating delayed graft function rates, daily urinary output, as well as the evolution of mean serum creatinine at 1, 3, 5, 7, and 15 days. RESULTS: The warm ischemia time was 42.4 +/- 11 minutes among Celsior vs 46.9 +/- 17.9 minutes in the UW cohort (P = NS). The cold ischemia time was 18 +/- 4.5 hours in Celsior and 19 +/- 6.5 hours in UW (P = NS). Delayed graft function occurred in 48% of the Celsior group and in 52% of the UW group (P = NS). Mean serum creatinine levels and mean daily urinary output were also similar. One- and 5-year graft survivals of kidneys preserved with Celsior were 91.8% and 79.3% compared with 96% and 87.4% for UW without any significant statistical difference. CONCLUSIONS: Our data show that the preservation of kidneys from elderly donors in Celsior solution is equivalent to that of UW solution.

Acute diverticulitis with colon perforation in renal transplantation.

INTRODUCTION: Acute diverticulitis with colon perforation is a serious condition in transplant recipients. The aim of this study was to analyze our experience with colon perforations among 875 renal transplant recipients between January 1986 and September 2004. METHODS: Patients were analyzed by age, gender, steroid dosage, time interval from the transplantation, delay between symptoms and surgery, clinical presentation, surgical procedure, graft and patient outcomes. RESULTS: We identified 8 patients with colon perforation. The incidence of perforation was 0.9%. Mean age at the the time of perforation was 58.5 years. Fever, abdominal pain, localized or diffuse signs of peritonitis, and leukocytosis were present in 7 patients (87.5%). Three patients (37.5%) were on steroid-free immunosuppression, whereas in 2 cases (25%) the steroid dosage was >20 mg/d. The mean interval between transplantation and perforation was 4.1 years. Two episodes (25%) occurred within 1 month following transplantation and the other 6 (75%) between 1 and 15 years. The interval between the onset of symptoms and surgery was longer than 48 hours in 1 patient (12.5%). In 5 cases (62.5%), a Hartmann procedure was performed; in 2 patients (25%), a resection with primary anastomosis was preferred. The last patient had a direct suture of the colon. Mortality rate was 12.5%. At a median follow-up of 6.1 years, 6 patients (75%) are alive with 5 functioning grafts. CONCLUSIONS: Colon perforations in renal transplant recipients remain a challenging surgical problem. An aggressive diagnostic attitude and an immediate surgical treatment may contribute to significantly decrease the incidence and the mortality of this complication.

[Vascular homografts: clinical results].

The authors review the results of clinical experiences regarding arterial and venous homografts. For the treatment of mycotic aneurysms and infected prostheses, in situ repair with vascular homografts represents a valuable alternative to conventional surgical treatments. In fact the large caliber arterial homografts allow safe in situ reconstruction, decrease early and midterm mortality and reinfection rates; the best results are achieved in case of infected grafts, whereas the prognosis of vasculo-enteric fistula remains very poor. The small caliber arterial homografts also have demonstrated satisfactory results in term of patency, although further experiences with longer follow-up are required. Vein homograft constitutes an alternative by-pass conduit for limb revascularisation in patients who lack adequate autogenous vein: although limb salvage rate is satisfactory, long term patency rate is poor when compared with autogenous veins. Improvement of preservation methodics, pharmacological control of rejection and tissue engineering represent the future perspectives in this field.
