[Pancreas transplantation with isolated blood supply through the splenic artery]. / Transplantatsiia podzheludochnoi zhelezy s izolirovannym krovosnabzheniem po selezenochnoi arterii.

In multiple organ procurement, taking into consideration certain peculiarities of the vascular architectonics of the celiac trunk or an iatrogenic injury to the superior mesenteric artery, it is impossible to perform standard arterial reconstruction of a pancreas transplant with the use of a Y-shaped vascular allograft. This results in refusal from transplanting a potentially suitable organ. The purpose of our study was to assess the possibility of transplantation of the pancreatoduodenal complex with isolated blood supply via the splenic artery. Between January 2008 and November 2016, transplantation of the pancreas was carried out in a total of 20 patients (9 men and 11 women aged from 26 to 40 years, mean age 37.2±5.6 years). Depending on the number of the major arteries supplying the pancreas, the patients were divided into 2 groups. No statistically significant between-group differences in the parameters of volumetric blood flow determined by means of CT perfusion, in the majority of laboratory findings or therapeutic outcomes were revealed. Based on assessment of the function and quality of pancreatic blood supply, we proved feasibility of transplantation of the pancreatoduodenal complex with isolated blood supply through the splenic artery.

[Pancreas transplantation followed by stumpless duodenal exocrine drainage]. / Transplantatsiia podzheludochnoi zhelezy s bezkul'tevym duodenal'nym drenirovaniem.

Pancreas transplantation followed by stumpless duodenal exocrine drainage was performed in 2 patients. Primary kidney and pancreas graft function was noted in both cases. Two procedures of pancreas transplantation followed by stumpless duodenal exocrine drainage were carried out for the first time. Perhaps, absent donor duodenal stump has several advantages for the further course of postoperative period that may be confirmed in prospective trials.

[Preventive anterior abdominal wall repair in recipients of renal allograft]. / Preventivnaia proteziruiushchaia plastika perednei briushnoi stenki u retsipientov pochechnogo allotransplantata.

AIM: Retrospective analysis of safety and efficacy of preventive anterior abdominal wall repair in recipients of renal allograft. MATERIAL AND METHODS: Kidney transplantation was performed in 396 patients with terminal renal failure within January 2015 - May 2017. Preventive endoprosthetics (PE) was applied in 28 (7.1%) patients. There were 7 women (26.9%) and 19 men (73.1%) aged 25-69 years (mean 44.5 (35, 56) years). Median of body mass index (BMI) was 27.5 (23.9, 29.9) kg/m2. RESULTS: Postoperative morbidity was 42.3%. Complications were mild (type I and II) and did not require invasive treatment. Postoperative morbidity was similar regardless protocol of immunosuppressive therapy (IST). CONCLUSION: Preventive abdominal wall repair after kidney transplantation is effective and safe to prevent postoperative hernia.

Retroperitoneal Pancreas Transplantation With the Use of Duodenal Drainage via "Button Technique": First Clinical Practice (Case Report).

The persistent relative high incidence of duodenum-associated surgical complications significantly reduces pancreas grafts' (PG) and recipients' survival rates. A 31-year-old female patient underwent retroperitoneal pancreas transplantation with the use of PG exocrine drainage into the recipient's duodenum via the "button technique" approach. An uncomplicated postoperative period with satisfactory function of both transplants (pancreas and kidney) was noted. This was the 1st time ever that the transplantation was performed with the use of retroperitoneal placement of the pancreas transplant and duodenal drainage via the "button technique" approach. It is possible that the absence of the duodenal stump in the donor's transplant has a number of benefits in the postoperative period, which can be confirmed during the follow-up observations.

CURRENT CAPABILITIES OF COMPUTED TOMOGRAPHY AND MAGNETIC RESONANCE IMAGING FOR THE DETECTION OF COMPLICATIONS AFTER COMBINED PANCREAS AND KIDNEY TRANSPLANTATION.

Objective: to give computed tomography (CT)- and magnetic resonance imaging (MRI)-based new anatomic-topographic relationships in patients after combined pancreas and kidney transplantation and to describe main visualization tasks and the types and frequency of various complications occurring in different periods after transplantation. Material and methods. Spiral CT and MRI images were analyzed in 45 patients after pancreas and kidney transplantation. A total of 51 studies (35 CTs and 16 MRIs) using intravenous contrast enhancement (n=34 (66%)) were performed. Results. A total of 55 complications, among which pancreatitis after pancreas transplantation was most common (55%), were found. Necrotizing pancreatitis following pancreas transplantation, which required open operative or percutaneous intervention, was diagnosed in 6.6%. Vascular complications were detected in 22%. Conclusion. The current capabilities of CT and MRI enable us to quickly obtain objective information on the status of transplanted organs, their vascular architectonics, as well as on the presence and type of occurred complications. Timely correction of identified complications positively affects the survival of transplanted organs and quality of life in a recipient.

Simultaneous pancreas-kidney transplantation with duodeno-duodenal anastomosis.

Simultaneous pancreas-kidney transplantation (SPKT) is now accepted as the method of choice for patients with insulin-dependent diabetes mellitus (type I) who have end-stage renal disease (ESRD). We believe that retroperitoneal positioning of the donor pancreas with the formation of duodeno-duodenal anastomosis is the most physiologically relevant. Starting in January 2008, the SPKT was chosen as the treatment method of 32 patients with diabetes mellitus. In 15 cases comprising group I (46.9%), the pancreas was placed intra-abdominally (including the formation of the duodeno-jejunal anastomosis). In the remaining 17 patients (53.1%) comprising group II, the pancreas was positioned retroperitoneally (including the formation of the duodeno-duodenal anastomosis). We compared the main parameters of the early postoperative period in these groups. There were no substantial differences between the groups in the prevalence of immunological (13.3% and 11.8%, P = .9), surgical (20% and 23.5%, P = .81), and infectious complications (20% and 5.9%, P = .23). On discharge there were no significant differences in the values of the following between the two groups, respectively: serum creatinine values, 112.7 ± 31.2 and 104.8 ± 54.6 µmol/L, P = .17; glomerular filtration rate, 73.5 ± 28.6 and 78.7 ± 24.9 mL/min, P = .55; α-amylase, 121.9 ± 63.6 and 150.1 ± 72.1 U/L, P = .27; pancreatic amylase, 102 ± 51.5 and 122.5 ± 75.4 U/L, P = .6; lipase, 115.4 ± 67.3 and 96 ± 65.7 U/L, P = .5; С-peptide, 4.44 ± 1.9 and 4.02 ± 2.4 ng/mL, P = .47; HbA1c, 5.45 ± 0.8% and 5.56 ± 1.12%, P = .9; and intact insulin, 12.2 ± 5.4 and 12.9 ± 8.8 mcIU/mL, P = .95). SPKT remains the best method of medical and social rehabilitation for patients who have diabetes mellitus (type-I) with ESRD. Compared to the classic method, we have seen no significant deviations in either of the following: the qualitative features marking the restoration of function of the two transplanted organs and/or the quality of compensation of carbohydrate metabolism, incidence of rejection, and graft loss. At the same time, retroperitoneal positioning of the pancreas exhibited lower repeat surgery rates.

[Plasmapheresis in combined treatment of acute rejection crises after kidney transplantation]. / Primenenie plasmafereza v kompleksnoi terapii ostrykh krizov ottorzheniia posle peresadki pochki.

The aim of the study was assessment of effectiveness and safety of extracorporeal procedures (plasmapheresis) in prevention and combined treatment of acute rejection crises (ARC) after kidney transplantation in patients at high risk to develop acute immunological conflicts in early postoperative period. 94 patients aged 21-56 years after allotransplantation of cadaver kidney (ATCK) entered the study. They were divided into two groups: group 1 patients (n = 47) received plasmapheresis procedures in combined preventive and therapeutic treatment of ARC; matched group 2 patients (n = 47, retrospective) received the same therapy but plasmapheresis. In both groups there were many patients with a high titer of pre-existing antibodies and massive hemotransfusions in the past. The analysis covered also recipients with the second ATCK (9 and 4 patients, respectively). After ATCK both groups received three-component immunosuppressive treatment (neoral, prednisolone, azatioprin and/or sell-cept). The analysis of the transplant and recipient 11-month survival has estimated that it was 93.6 and 91.5% for the recipients, respectively, and 91.5 and 76.5% for the transplanted kidney for group 1 and 2, respectively. The conclusion is that plasmapheresis in combined prevention and treatment of ARC by humoral type in sensitized patients (high titer of the pre-existing antibodies, repeat transplantations, hemotransfusions) is pathogenetically grounded and lowers the percentage of irreversible episodes of acute transplant rejection early after surgery.
