Management of Chylous Ascites After Laparoscopic Nephrectomy for Living Kidney Donor: A Case Report and Literature Review.

Kidney transplant is currently the elective treatment of choice for end-stage renal disease. Laparoscopic living donor nephrectomy (LLDN) has substantial advantages over open nephrectomy. Chylous ascites (CA) is a rare surgical complication after the LLDN; there are few reports in the literature. We present a case report of a 58-year-old woman who started CA on the 21st day post operation. The recommended initial therapeutic approach to suspend the fat in the diet and place percutaneous drainage was not enough. It was decided to jointly introduce fasting and total parenteral nutrition with the administration of octreotide, resolving the complication completely in 15 days with no need for the patient to undergo surgery. The conservative management, during the first 4 to 8 weeks after the diagnosis is the best option. Surgery is generally recommended if conservative management fails. The prevalence of CA varied between 0% and 6.2% of LLDNs. In our experience of 87 LLDNs, we only presented 1.15% for this complication. There are 62 cases reported in the international literature. The mean presentation was 14 days after LLDN. All patients underwent conservative treatment, and only 15 patients (24%) went to surgery after the failure of conservative management. It would be highly useful, considering the disparity of the prevalence, if the bibliographic reports detail what hemostatic and sealing techniques are used in an LLDN. In this way it would be possible to identify which factor affects a complication like this one.

Timing of hepatic artery reperfusion and biliary strictures in liver transplantation.

During orthotopic liver transplantation (OLT), biliary tract perfusion occurs with hepatic artery reperfusion (HARP), commonly performed after the portal vein reperfusion (PVRP). We examined whether the average time interval between PVRP and HARP impacted on postoperative biliary strictures occurrence. Patients undergoing OLT from 2007 to 2009 were included if they were ≥18 years old, had survived 3 months postoperatively, and had data for PVRP and HARP. Patients receiving allografts from DCD donors were excluded. Patients were followed for 6 months post-OLT. Seventy-five patients met the study inclusion criteria. Of these, 10 patients had a biliary stricture. There was no statistical difference between those with and without biliary stricture in age, gender, etiology, MELD score, graft survival, and time interval between PVRP and HARP. Ninety percent of patients with biliary stricture had a PVRP-HARP time interval >30 minutes, as opposed to 77% of patients without biliary stricture. However, this was not statistically significant. The cold ischemia time was significantly different between the two groups. Time interval for HARP after PVRP did not appear to affect the development of biliary strictures. However, 30 minutes may be suggested as a critical time after which there is an increase in biliary stricture occurrence.
