[Surgical treatment of hyperparathyroidism--personal experience].

The authors submit their own experience with the surgical treatment of all types of hyperparathyroidism (HPT). Since 1992 till the end of April 2002 in the Institute of Clinical and Experimental Medicine 151 operations were performed in 132 patients, in particular secondary HPT (69.8%). Among surgical operations partial parathyroidectomy (PTE) predominated, as a rule without peroperative implantation of parts of the removed parathyroid glands(PT)(64.8%). The high ratio of this type of operations was due among others to a recent increase of tertiary posttransplantation HPT. Advanced secondary HPT of haemodialyzed patients was treated by total PTE with implantation of PT tissue. The incidence of surgical complications was low (7.1%) and insignificant from the aspect of the long-term postoperative condition. Persisting or relapsing HPT was revised in 15 patients (in 12.6% of all operations).

[Pancreas transplantation: who and when?].

Hyperglycemia is an important factor in the development and progression of the complications of diabetes. Pancreas transplantation is currently the only method able to achieve sustained normoglycemia in type I diabetes. By now, this procedure has become an accepted treatment option combined with kidney transplantation for selected patients with end-stage diabetic nephropathy. The definite benefits of pancreas transplantation comprise relieve from insulin administration, superb glycemic control, improved quality of life and long-term survival of patient with severe autonomic neuropathy. Presumed benefits represent stabilization or slowing of progression of microvascular complications. Definite disadvantages are the risk of the surgical procedure, graft rejection and the necessity of permanent immunosuppression. Isolated pancreas transplantation in nonuremic type-1 diabetic patients is still controversial. Diabetic complications of the potential recipient have to be potentially correctable by the transplantation and their significance must exceed all risks of the operation and life-long immunosuppression. Currently, approx. 25 combined transplants are performed per year in IKEM with the results comparable to those reported by the International Pancreas Transplant Registry. Seven nonuremic type-1 diabetic recipients of 8 operated in IKEM by June 2000 have been insulin-independent for 1-33 months. The main indication for isolated pancreas transplantation is brittle diabetes with hypoglycemia unawareness syndrome and labile diabetes with severe autonomic neuropathy and rapid progression of microangiopathy despite appropriate intensified insulin therapy.

[The urinary tract in graft recipients and urologic complications after kidney transplantation].

BACKGROUND: Urological complications after renal transplantation condition reduce graft survival and function. It may be assumed that an important part, in addition to technical factors during removal and implantation of the organ may be played also by factors of the recipient. The authors investigated whether in the development of some urological complications (urinary fistulae and urinary tract dilatation) also pathological changes of the urinary tract of the recipient, kidney diseases leading to renal failure or the development of urinary flow rate during the first days after transplantation of the kidney participate. METHODS AND RESULTS: The authors investigated 77 patients after renal transplantation where during the period from Jan. 1992 till Dec. 1996 a urinary fistula developed (42 cases), dilatation of the urinary tract (32) or both complications (3). The control group was formed by 100 patients without urological complications who did not differ as to demographic data, basic immunosuppressive treatment and who had transplantations during the same period and by the same surgical techniques. The assembled data were evaluated statistically, the two groups being compared by means of t-test, chi 2 test and the non-parametric Mann-Whitney test resp. The authors investigated factors which might participate in the quality of the recipient urinary tract, in particular the recipient's age. In the group of urologically complicated cases there were significantly (p < 0.05) more patients above 55 years. There were also more males (67.5% vs. 32.5%, p < 0.05). In further factors such as the ratio of BMI ratio or the underlying kidney disease leading to renal failure and the presence of diabetes mellitus the authors did not record significant differences. The residual urinary flow rate, duration of dialysis treatment before transplantation and the number of transplantations did not differ significantly. The authors tried to evaluate the possible influence of urinary flow rate on the development of urological complications after transplantation of the kidney. CONCLUSIONS: The assembled findings support the idea that the development of a urinary fistula or dilatation of the urinary tract were not significantly influenced by changes in the urinary tract of the recipient conditioned by the period of the reduced function, as may be assumed on the basis of the time of dialysis treatment. The development of the investigated urological complications was not significantly influenced by the presence of underlying kidney diseases nor by increased urinary flow rate during the first days after transplantation. The authors did not confirm the risk of re-transplantation. An significant effect on the development of urological complications could be exerted by male sex and age above 55 years.

[Surgical treatment of ischemia in the diabetic foot syndrome].

The authors present their results of the treatment of diabetic foot critical ischemia by means of surgical revascularisation together with minor amputation or debridement. They discuss the causes of higher amputations and re-amputations in revascularised ischemic diabetic lower limbs and presents patency rates in different types of peripheral arterial bypasses. The authors evaluated 81 diabetic feet with chronic critical ischemia, where they performed 50 arterial bypass procedures in the 50 limbs (13 femoropopliteal, 13 femorodistal, 19 pedal bypasses and 5 aorto/ilicofemoral or extraanatomical bypasses). 41 minor amputations or debridements (82%), 6 minor re-amputations (12%) was performed in the group of 50 revascularised limbs. The primary patency rates, secondary patency rates and limb salvage was achieved 92%, 92% and 92% in femoropopliteal bypass, 91%, 91% and 92% in femorodistal bypass, 78%, 83% and 84% in pedal bypass, respectively. The average follow-up time was 11.4 months. 6 minor re-amputations (12%) and 5 high amputations was necessary to perform in the group of 50 revascularised lower limbs. The main cause of re-amputation and high amputation was continuing ischemia. 30 day mortality rate was 0%, 30 day morbidity rate was 8% (myocardial infarction and pulmonary embolism).

100 pancreas transplantations with extraperitoneal graft placement.

The authors present the results of 100 pancreatico-duodenal grafts placed extraperitoneally with the bladder drainage. The onset of pancreatic graft function was immediate in all cases and the patients became insulin free. Despite the extraperitoneal graft placement the incidence of surgical complications was low. The only exception was slightly impaired wound healing. The Authors claim that this surgical technique allows the elimination of intraperitoneal infection and easy performance of the graft biopsy.

Renal transplantation combined with aortofemoral bypass using a fresh arterial allograft.

Aortoiliac atherosclerosis is frequently encountered in renal failure patients waiting for renal transplantation. Staged or simultaneous surgical repair of aortoiliac lesions with renal transplantation is possible at reasonable risk. Arterial reconstruction is most commonly performed using an artificial prosthesis. Another option is the use of a fresh or preserved arterial allograft. In our institute, about 180 cadaveric transplantations are performed each year. Over the past 2 years, three patients with chronic renal failure and obliterative disease of the abdominal aorta and iliac arteries underwent aortofemoral bypass using a fresh arterial allograft combined with kidney transplantation from the same donor. The procedures as well as the postoperative course were uneventful. There was an immediate development of function of the renal transplant. Combined arterial reconstruction and transplantation, managing both conditions at a time, is convenient for the patient mainly because it means undergoing only one general anesthesia during one hospitalization. Moreover, the risk of infection of the vascular prosthesis is somewhat reduced. Disadvantages are that the availability of the arterial allograft is dependent on a suitable donor and the limited body of experience with the behavior of the arterial allograft in patients with chronic immunosuppression.

[Pedal bypass in the treatment of critical ischemia in the diabetic foot].

A formerly established theory on obliteration of diabetic foot arteries was dismissed. In the last decade, diabetic foot revascularization using so called very distal bypass has became a routine procedure. The reconstructions are undertaken in patients with chronic critical limb ischemia. This paper presents our initial experience with this, not yet widely used, operative technique in 16 patients who had a total of 14 pedal bypass procedures performed. The parameters we monitored included the 3-, 6-, and 12-month patency rates, defect healing, and limb salvage rates. The primary and secondary patency rates were 64.3% and 78.6% at 3 months; 55.5% and 66.7% at 6 months; and 50% and 75% at one year, respectively. The overall limb salvage rate for the above periods was 92.9%. All defects healed following successful revascularization using pedal bypass. In patients where bypass could not be established, limb salvage was accomplished in one in three cases only.

[Percutaneous lumbar sympathectomy--presentation of a new trans-diskal approach].

The authors present the technique of chemical lumbar sympathectomy by an anatomically new medial transdiscal approach. On a group of 80 operations they analyze the indication criteria, complications and results of this method. They compare the percutaneous technique of severing of the sympathetic nerve with the classical surgical approach. In 41 patients where a modified transdiscal approach was used the authors did not encounter any serious complications. Using thin needles (minimum 23-G) they recommend this method as an alternative of the classical approach of Kappis.

[Repeat kidney transplantation].

BACKGROUND: The objective of the study was an analysis of results of repeated kidney transplantations (Tx2, Tx3) implemented during the first 29 years of activities of the Transplantation Centre of the Institute of the Clinical and Experimental Medicine in subjects with a different maintenance immunosuppression. METHODS AND RESULTS: The retrospective study pertains to 134 Tx2 and 17 Tx3 in 134 non-diabetic subjects: 43 of them had during Tx1 and Tx2 (1966-1981 and 1966-1985 resp.) immunosuppression on the basis of azathioprin (Aza, sub-group AA), 42 during Tx1 (1972-85), Aza, while during Tx2 (1984-85) immunosuppression on the basis of cyclosporin (CyA, subgroup AC) and 49 both during Tx1 and Tx2 (1985-93 and 1986-95 resp.) CyA (subgroup CC). Compared was survival of grafts by the actuarial method (with regard to all losses regardless of cause) by the end of the 4th year inside the subgroups (Tx2, vs. Tx1 and Tx3 vs. Tx2 in the same subjects) and between subgroups (Tx1 vs. Tx1 and Tx2 vs. Tx2 in different subjects). Moreover in paired investigations the survival of recipients and grafts after Tx2 was compared after immunosuppression on the basis of CyA with the same parameters after Tx1 in different subjects with the same immunosuppression, operated at approximately the same time (n = 81) and survival of subjects with Tx1 + Tx2 on the CC regime regardless whether the second grafts functioned at the time of the last examination, with survival of subjects after Tx1 where after graft failure Tx2 was not performed (n = 34). Prophylaxis with antilymphocyte globulins was not used. Survival of second and first grafts did not differ in any of the subgroups, third grafts survived at the end of the third year more frequently than second grafts (66 vs. 18%, p < 0.01). Second grafts in CC survived more than in AA (55 vs. 28%, p < 0.01). In the paired study Tx2 vs. Tx1 the survival of grafts and recipients was the same (88 vs. 89%, N.S. and 47 vs. 62% resp.), in the paired study Tx1 + Tx2 vs. Tx1 more subjects with Tx1 + Tx2 survived 10 years after Tx1 than subjects who did not have Tx2 (82 vs. 49%, p < 0.05). CONCLUSIONS: A further transplantation of the kidney after functional loss of the first graft is the method of choice: the mortality is low, the probability of several years' function is considerable and the prognosis as regards quality and length of life better than with regular dialysis treatment.

[Conversion of drainage of a pancreatic transplant from the urinary bladder to the intestine in a recipient].

The most frequently used surgical technique in transplantations of the pancreas is to connect the duodenum of the graft with the urinary bladder of the recipient. Introduction of this method led during the last five years to marked improvement of results. On the other hand duodenocystoanastomosis is a frequent cause of metabolic and urological complications in patients after transplantation. The authors present the case-record of a female patient after combined transplantation of the pancreas and kidney where surgical conversion of the drainage of pancreatic juice from the urinary bladder to the gut was necessary.

[Techniques and tactics in multiorgan harvesting].

The eighties and nineties are characterized by potent development of transplantology. Despite this the number of patients with organ failures waiting for a suitable organ is steadily increasing. Due to the permanent shortage of donors transplantation surgery tries to implement the maximum possible multiple organ collection. In the conclusion the authors emphasize the importance of satisfactory cooperation of the anaesthesiologist attending donors and the organ collection teams.
