RESUMO
Bile duct size discrepancy in liver transplantation may increase the risk of biliary complications (BCs). The aim of this study was to evaluate the safety and outcomes of the eversion bile duct anastomosis technique in deceased donor liver transplantation (DDLT) with duct-to-duct anastomosis. A total of 210 patients who received a DDLT with duct-to-duct anastomosis from 2012 to 2017 were divided into 2 groups: those who had eversion bile duct anastomosis (n = 70) and those who had standard bile duct anastomosis (n = 140). BC rates were compared between the 2 groups. There was no difference in the cumulative incidence of biliary strictures (P = 0.20) and leaks (P = 0.17) between the 2 groups. The BC rate in the eversion group was 14.3% and 11.4% in the standard anastomosis group. All the BCs in the eversion group were managed with endoscopic stenting. A severe size mismatch (≥3:1 ratio) was associated with a significantly higher incidence of biliary strictures (44.4%) compared with a 2:1 ratio (8.2%; P = 0.002). In conclusion, the use of the eversion technique is a safe alternative for bile duct discrepancy in DDLT. However, severe bile duct size mismatch may be a risk factor for biliary strictures with such a technique.

BACKGROUND: To assess the impact of participation of multiorgan procurement (MP) by general surgery (GS) residents on surgical knowledge and skills, a prospective cohort study of GS residents during transplant surgery rotation was performed. METHODS: Before and after participation in MPs, assessment of knowledge was performed by written pre and post tests and surgical skills by modified Objective Structured Assessment of Technical Skill (OSATS) score. Thirty-nine residents performed 84 MPs. RESULTS: Significant improvement was noted in the written test scores (63.3% vs 76.7%; P < 0.001). Better surgical score was associated with female gender (15.4 vs 13.3, P = <0.01), prior MP experience (16.2 vs 13.7, P = 0.03), and senior level resident (15.1 vs 13.0, P = 0.03). Supraceliac aortic dissection (P = 0.0017) and instrument handling (P = 0.041) improved with more MP operations. CONCLUSIONS: Participation in MP improves residents' knowledge of abdominal anatomy and surgical technique.

The inferior vena cava (IVC) is the most common site of leiomyosarcomas arising from a vascular origin. Leiomyosarcomas of the IVC are categorized by anatomical location. Zone I refers to the infrarenal portion of the IVC, Zone II from the hepatic veins to the renal veins, and Zone III from the right atrium to the hepatic veins. This is a rare presentation of a Zone I-III leiomyosarcoma. Fifty-two-years-old female with a medical history significant only for HTN was admitted to the hospital with bilateral lower extremity edema and dyspnea. Two-dimensional echo demonstrated a right atrial thrombus, extending into the IVC. On subsequent CT and MRI, a 15 cm mass was noted that began in the right atrium and extended into the IVC, with continuation below the renal veins to above the level of the confluence of the common iliac veins. The patient underwent a complete resection of the mass, replacement of the IVC with Dacron graft, total hepatectomy and bilateral nephrectomy, with liver and kidney autotransplantation. Pathology was consistent with a high grade spindle cell sarcoma of vena cava origin. Patient was readmitted approximately 4 weeks postoperatively to begin adjuvant chemotherapy. This case represents a zone I-III IVC leiomyosarcoma treated with surgical R0 resection. This included a hepatectomy, bilateral nephrectomy, and hepatic and left renal autotransplantation. These complex tumors should be treated with surgical resection, and require a multidisciplinary approach.

Posttransplant lymphoproliferative disorder (PTLD) is a well-known complication associated with the transplant recipient. We chronicle a case of PTLD in a failed graft presenting as a small bowel obstruction in a pancreas-only transplant patient. While typical symptoms may be elusive in the complex immunosuppressed patient, graft pain along with persistent graft pancreatitis and a positive Epstein-Barr viremia should raise suspicion for an underlying PTLD.
RESUMO
OBJECTIVES: Adequate hepatic arterial (HA) flow to the bile duct is essential in liver transplantation. This study was conducted to determine if the ratio of directly measured HA flow to weight is related to the occurrence of biliary complications after deceased donor liver transplantation. METHODS: A retrospective review of 2684 liver transplants carried out over a 25-year period was performed using data sourced from a prospectively maintained database. Rates of biliary complications (biliary leaks, anastomotic and non-anastomotic strictures) were compared between two groups of patients with HA flow by body weight of, respectively, <5 ml/min/kg (n = 884) and ≥5 ml/min/kg (n = 1800). RESULTS: Patients with a lower ratio of HA flow to weight had higher body weight (92 kg versus 76 kg; P < 0.001) and lower HA flow (350 ml/min versus 550 ml/min; P < 0.001). A lower ratio of HA flow to weight was associated with higher rates of biliary complications at 2 months, 6 months and 12 months (19.8%, 28.2% and 31.9% versus 14.8%, 22.4% and 25.8%, respectively; P < 0.001). CONCLUSIONS: A ratio of HA flow to weight of < 5 ml/min/kg is associated with higher rates of biliary complications. This ratio may be a useful parameter for application in the prevention and early detection of biliary complications.
