Laparoscopic Donor Nephrectomy of Dual Renal Artery Kidneys: Single Center Experience.

Unlabelled: Multiple renal artery (MRA) kidneys represent a special challenge for surgeons, during both donor nephrectomy and renal transplantation.

Aims: This study aims to evaluate both donors and recipients outcomes of laparoscopically procured dual renal artery (DRA) kidneys. Patients and We reviewed the medical records of all living kidney donors who underwent laparoscopic donor nephrectomy between April 2009 and December 2014, and their recipients.

Colorectal Cancer Carcinogenesis: a Multivariate Genetic Model in a Cohort of Romanian Population.

Background: The molecular mechanism of carcinogenesis of sporadic colorectal cancer (CRC) involves genes with roles in folate metabolism, genes involved in metabolization of carcinogenic compounds from diet and tobacco smoke, and genes related to the DNA repair process. The aim of the study was to examine whether the MTHFRC677T, MTHFR- A1298C, TS-2rpt/3rpt, TS-1494del6bp, NAT2*5C-C481T, NAT2*5A-T341C, NAT2*6B-G590A, NAT2*7B-G857A, NAT2*18-A845C, GSTM1-null, XRCC1-Arg399Gln, XRCC3-Thr241Met, XPD-Lys751Gln genetic variations are associated with CRC prognosis, in the presence of environmental and demographic factors.

Methods: We genotyped 150 patients diagnosed with sporadic CRC using PCR-RFLP and sequencing methods.

N-acetyl transferase 2/environmental factors and their association as a modulating risk factor for sporadic colon and rectal cancer.

Objectives: The aim of this study was to evaluate the association between environmental factors and colon or rectal cancer after adjusting for N-acetyl transferase 2 (NAT2) phenotypes.

Methods: Ninety-six patients with sporadic colon cancer, 54 with sporadic rectal cancer and 162 control subjects were genotyped for NAT2-T341C, G590A, G857A, A845C, and C481T using sequencing and PCR-RFLP analysis.

Results: The risk for colon cancer was increased in carriers of the homozygous negative genotypes for NAT2*5C-T341C, NAT2*6B-G590A, NAT2*7B-G857A, NAT2*18-A845C, and NAT2*5A-C481T.

Hepaticojejunostomy for the management of sump syndrome arising from choledochoduodenostomy in a patient who underwent bariatric Roux-en-Y gastric bypass: A case report.

Introduction: Rapid weight loss following bariatric surgery is associated with high incidence of gallstones and complications that may need bilioenteric diversion. This presents a specific challenge in the management of this group of patients.

Case Presentation: A 37 years old female underwent a Roux-en-Y gastric bypass (RYGB) in 2008 for morbid obesity.
