Objective: In this retrospective study, we compared the postoperative complications by using both the Clavien--Dindo classification and the Revised 2016 International Study Group on Pancreatic Surgery (ISGPS) classification methods after pancreaticoduodenectomy. Materials and Methods: The data of patients were retrospectively reviewed. Pancreaticojejunostomy (PJ) and pancreaticogastrostomy (PG) were performed on 41 and 40 patients, respectively. The patients were assigned into two groups for anastomosis types and compared with each other according to postoperative complications. The postoperative follow-up period of the patients was limited to 90 days. Results: No significant difference was detected between the two groups in terms of gender (P = .581) and age (P = .809). According to the Clavien--Dindo classification system, grade 1 complication rates were 29.3% and 35.0% in PJ and PG groups, respectively. Also, grade 2 complication rates were 34.1% and 32.5% in PJ and PG groups, respectively. Besides, grade 3B complication rates were 9.8% and 17.5% in PJ and PG groups, respectively. No grade 3A, grade 4A, and grade 4B complications were detected in both groups. But, grade 5 complications rates were 2.4% and 5.0% in PJ and PG groups, respectively. Based on the ISGPS classification system, the pancreatic fistulas were classified. The biochemical leak rates were calculated as 26.8% and 37.5% in PJ and PG groups, respectively. The rates were 14.6% and 10% in PJ and PG groups, respectively, for grade B complications. Also, grade C complication rates were 9.75% and 12.5% in PJ and PG groups, respectively. No statistically significant differences were detected between the two groups for postoperative complications. Conclusion: The evidence from this retrospective study suggests that there is no difference between the two types of pancreatic anastomosis techniques (PJ or PG) in terms of the rate of postoperative complications.

Objective: Multiple renal artery grafts of kidney transplant patients developing complications and results for long-term kidney function were evaluated. Material and Method: From 2010 to 2014, 115 kidney transplant patients were evaluated retrospectively. A sum of. 115 donor nephrectomies were performed in our instution. Kidney were transplanted with a single artery to 99 patients and sixteen (approximate 14%) with more than one. For five of these 16 patients, the organs were transplanted from a cadaver and eleven were transplanted from living donors. Results: Mean age was 38.5 years (range 9-58 years), mean follow up time was 22,5 month (min. 3,5 and max. 41 month) and mean cold ischemia time was 153 minutes for living donor transplantations and 1396 minutes for cadaveric transplantation, and also warm ischemia time was 236 seconds for living donor transplantation. In all cases, the grafted kidney began to function immediately after reperfusion. Fourteen of the recipients had no any early kidney dysfunction, a problem that is usually attributed to prolonged anastomosis time. Conclusion: Transplanting kidneys with multiple renal arteries may result in significant risks. Prolonged cold or hot ischemia time may elevate incidence of non functional graft and rejection. Results of this study points that unifying artery anastomosis at the backtable would reduce the risk. [ABSTRACT FROM AUTHOR]

Congenital choledochal cysts are rare in adults. Due to the risk of developing cholangiocarcinoma, the current standard of care is complete excision of the cyst and reconstruction with hepaticojejunostomy. So far, more than 200 laparoscopic resections have been reported in adults, the majority being from Far Eastern countries over the last five years. Herein, the technique of laparoscopic type I choledochal cyst excision and hepaticojejunostomy is presented in a 37-year-old male with an accompanying video. The advantages of laparoscopic surgery are applicable for choledochal cyst excision as well. We believe that teamwork, expertise on intracorporeal suturing and hepatobiliary surgery are central issues for this operation. [ABSTRACT FROM AUTHOR]

Methotrexate is a chemotherapeutic agent used for many cancer treatments. It leads to toxicity with its oxidative injury. The purpose of our study is investigating the medical ozone preconditioning and treatment has any effect on the methotrexate-induced kidneys by activating antioxidant enzymes in rats. Eighteen rats were divided into three equal groups; control, Mtx without and with medical ozone. Nephrotoxicity was performed with a single dose of 20 mg/kg Mtx intraperitoneally at the fifteenth day of experiment on groups 2 and 3. Medical ozone preconditioning was performed at a dose of 25 mcg/ml (5 ml) intraperitoneally everyday in the group 3 and treated with medical ozone for five more days while group 2 was received only 5 ml of saline everyday for twenty days. All rats were sacrificed at the end of third week and the blood and kidney tissue samples were obtained to measure the levels of TNF-α, IL-1β, malondialdehyde, glutathione and myeloperoxidase. Kidney injury score was evaluated histolopatologically. Medical ozone preconditioning and treatment ameliorated the biochemical parameters and kidney injury induced by Mtx. There was significant increase in tissue MDA, MPO activity, TNF-α and IL-1β (P<0.05) and significant decrease in tissue GSH and histopathology (P<0.05) after Mtx administration. The preconditioning and treatment with medical ozone ameliorated the nephrotoxicity induced by Mtx in rats by activating antioxidant enzymes and prevented renal tissue.
