Surgical treatment of cholecystic disease in renal transplant candidates / 中国普通外科杂志

Objective To investigate the morbidity of cholecystic disease in renal transplant candidates and study the indications of prophylactic laparoscopic cholecystectomy(LC) for renal transplant candidates with cholecystic disease. Methods The incidence of cholecystic disease in 286 renal transplant candidates in our institution in recent four years was retrospectively reviewed.All the candidates had received one or more ultrasonographic examinations. Results Cholecystic disease was found in 32 of 286 candidates ((11.1)%), including cholelithiasis in twenty(62.4%, 20/32), sludge in six(18.8%, 6/32)and polypoid lesion in six(18.8%, 6/32). Cholecystectomy had been performed in twenty candidates with symptomatic chronic cholecystitis before transplantation, including LC in fourteen and open cholecystectomy with small incision in six .Five of twelve candidates without symptoms received prophylactic LC electively .In three of the other 7 candidates acute cholecystitis occured within six month after transplantation.There was no death of the (candidates) and no grafts function loss occurred in this series. Conclusions Cholelithiasis is the major cause of cholecystic disease in renal transplant candidates. Electively prophylactic LC is recommended for the (candidates) with or without symptomatic cholecystitis before transplantation or before acute cholecystitis has (occured).

Postoperatiive renal hemodynamic in orthotopic liver transplant recipents / 中国普通外科杂志

Objective To investigate the renal hemodynamic changes after orthotopic liver transplantation(OLT)and the correlative parameters. Methods In 20 patients undergoing OLT for cirrhosis,the following renal arterial resistance index(RI) was measured before surgery and 7days,30days, 6 months and 1 year after operation by using color Doppler flow imaging(CDFI) and serum creatinine detection.Meanwhile the same parameters were measured in 10 healthy as controls. Results Both RI and serum Cr rised after OLT ( P 0.05). Conclusions Most alteration of renal hemodynamic parameters in cirrhosis are restored to normal after OLT in 1 year. Preoperative renal abnormalities and intraopterative alteration of hemodynamic may contribute to postoperative renal dysfunction. Cyclosporine (CsA) is the most likely etiologic agent of postoperative renal dysfunction.

Infection occurred with in short-term after orthotopic liver transplantation / 中国普通外科杂志

Objective To study the diagnosis and prophylaxis of postoperative infections within 1 month after orthotopic liver transplantation(OLT). Methods Clinical date of 38 consecutive patients who underwent OLT at our institution from 2001 to 2003 were retrospectively reviewed. Result Eighteen patients( 47.4% ) developed twenty-nine times infection after operation .Respiratory tract and peritoneum were the common infectious sites(37.9% and 24.1%). Enterobacter cloacae(8 of 29, 27.6%) , Escherichia coli(7 of 29, 24.1%),staphylococcus aureus(6 of 29, 20.7%) were the commonest bacterial.The mortality of infection was 38.9%(7/18). Identified risk factors for infection including: previous transplantation ; duration of operation; transfusion requirements during surgery; type of biliary anastomosis; delayed restoration of gastrointestinal function and persistent postoperative hyperglucocemia . Perioperative decontamination of the digestive tract had a protective effect. Conclusions Infections are a major cause of death among liver transplant recipients. Reducing risk factors of infection and perioperative decontamination of the digestive tract may decrease the occurrence of postoperative infection.
