comparison of analgesic effects of various administration methods of diclofenac sodium, transdermal, oral and intramuscular, in early postoperative period in laparoscopic cholecystectomy operations

The aim of this study was to compare the efficacy of oral, intra muscular and transdermal diclofenac sodium for pain treatment in patients undergoing laparoscopic cholecystectomy, and their effect on postoperative opioid consumption. Following informed consent, 90 ASA I-II patients scheduled for laparoscopic cholecystectomy were randomized into three groups. Group PO got oral diclofenac sodium 1 hour before the operation, Group IM 75 mg diclofenac sodium intra muscular and Group TD diclofenac sodium patch 6 hours before the operation. Patients were not premedicated. Routine anaesthesia induction was used. After the operation in post anaesthesia care unit tramadol HCl infusion was delivered by intravenous patient controlled analgesia [iv PCA]. Ramsey Sedation Score [RSS], Modified Aldrete's Score System[MASS] and Visual Analog Scale Pain Score [VAS] was used for postoperative evaluation. Postoperative opioid consumption was recorded. Demographic characteristics, intraoperative and postoperative hemodynamics of the patients were similar between groups. Postoperative VAS were lower at all time points in Group IM and Group TD than in Group PO. Lowest Postoperative RSS were in Group IM and the highest were in Group PO, and the difference between groups was significant. There was no significant difference in Postoperative MASS between groups. Postoperative tramadol consumption was statistically different between groups. Tramadol consumption in Group IM and Group TD was lower than Group PO. Postoperative nausea and vomiting was not observed. Local complications related to transdermal and intra muscular applications was not reported. In patients undergoing ambulatory laparoscopic cholecystectomy, a noninvasive application transdermal diclofenac sodium is as effective as intramuscular diclofenac sodium and can be preferred in postoperative pain treatment

Congenital Variants and Anomalies of the Pancreas and Pancreatic Duct: Imaging by Magnetic Resonance Cholangiopancreaticography and Multidetector Computed Tomography

Though congenital anomalies of the pancreas and pancreatic duct are relatively uncommon and they are often discovered as an incidental finding in asymptomatic patients, some of these anomalies may lead to various clinical symptoms such as recurrent abdominal pain, nausea and vomiting. Recognition of these anomalies is important because these anomalies may be a surgically correctable cause of recurrent pancreatitis or the cause of gastric outlet obstruction. An awareness of these anomalies may help in surgical planning and prevent inadvertent ductal injury. The purpose of this article is to review normal pancreatic embryology, the appearance of ductal anatomic variants and developmental anomalies of the pancreas, with emphasis on magnetic resonance cholangiopancreaticography and multidetector computed tomography.
