Impact of cirrhosis on surgical outcome after pancreaticoduodenectomy.

Aim: To elucidate surgical outcomes of pancreaticoduodenectomy (PD) in patients with liver cirrhosis.

Methods: We studied retrospectively all patients who underwent PD in our centre between January 2002 and December 2011. Group A comprised patients with cirrhotic livers, and Group B comprised patients with non-cirrhotic livers.

Pancreatic anastomotic leakage after pancreaticoduodenectomy. Risk factors, clinical predictors, and management (single center experience).

Background: Postoperative pancreatic fistula (POPF) after pancreaticoduodenectomy (PD) remains a challenge even at high-volume centers.

Methods: This study was designed to analyze perioperative risk factors for POPF after PD and evaluate the factors that predict the extent and severity of leak. Demographic data, preoperative, intraoperative, and postoperative variables were collected.

Effect of melatonin on estrogen and progesterone receptors in relation to uterine contraction in rats.

The present study was designed to investigate the possible modulator effect of melatonin on uterine estrogen and progesterone receptors in rats as well as the uterine response to oxytocin. Non-pregnant rats were pretreated with melatonin in a dose of 0.8 mg kg(-1) per day for 15 consecutive days.
