|Surgical complications after pediatric liver transplantation|
On that 5-year period 60 pediatric liver transplants were performed in our centre. The average age at the transplant was 4,7±4,4 years (between 0,08-15,9 years).
The number of pediatric hepatic transplants in our centre has been increasing annually during the studied period (Fig. 5).
The main transplantation indication was Biliary Atresia (BA) (14 patients), followed by metabolopathies (10 patients), there were other indications such as cholestatic diseases, cirrhosis and other diseases that represent a lower percentage of transplants. Indications of pediatric liver transplantation varies in the different age groups (Fig. 6).
From all patients, 33 received a Partial Liver Transplant (PLT) and 27 received Total Liver Transplant (TLT) (Fig. 7). From partial transplants 13 patients received Partial Cadaveric Transplant (PCT) the 39% and 20 patients received Partial Live Donor Transplants (PLDT) the 61%. PLT represent the 55% of all pediatric liver transplants (Fig. 8).
The complications, 29 in total, occurred in 25 patients, 42% of patients receiving a liver transplant suffered complications from the surgery.
Of the patients who experienced complications, the majority were in patients who had received partial hepatic transplants, 72,4% of the complications were in this group, although it did not show a statistical significance (p=0,871). 14 complications appeared in PLDT (48%), 7 in PCT (24%) and 8 in TLT (27,6%).
Children under 2 years of age received 23 transplants and 10 developed complications (43,5%), 40% of all patients who developed complications, not statistically different from other age groups (p = 0,86).
The patients transplanted by a metabolopathy were 11, 6 of them developed a surgical complication (55%) which represents a significantly higher proportion than other indications (p=0,011). Of the other indications, the patients transplanted by cholestasis and tumour diseases also showed significantly more complications with respect to the other indications, with a p value of 0,002 and <0,001 respectively.
There were 11 arterial and biliary complications (18% of the patients) respectively and 7 of venous (12% of the patients). Of the arterial 5 were stenosis, 5 thrombosis and 2 pseudoaneurisms. Of the venous complications 5 were stenosis and 2 were thromboses. And biliary 9 were stenosis and 2 bile extravasation.
