RESUMO
Background: common bile duct [CBD] stones exist among 12% of patients with cholelithiasis. They may result in some complications including pancreatitis and cholangitis. The common therapeutical method is endoscopic sphincterotomy during ERCP[Endoscopic Retrograde Cholangio-Pancreatography] and stones removal. This method does not have a reasonable success rate for stones with a diameter larger than 15 mm and may cause serious complications. The aim of this study was to evaluate the CBD stenting method in the treatment of large CBD stones
Materials and Methods: this study was performed on 32 patients who presented to the ERCP unit of Shahid Beheshti hospital in Qom with large CBD stones. Success rate in CBD clearing and rate of some complications including rupture of CBD, pancreatitis, and cholangitis were evaluated after the first ERCP for stent replacement, and the second for its removal
Results: the success rate in complete CBD clearing was 93.8%. A reduction in size and number of stones was seen during a 2-month period, which was statistically significant. No case of CBD rupture and cholangitis was detected and the incidence of pancreatitis was 18.8%
Conclusion: CBD stenting has a reasonable success rate for reducing the size and number of CBD stones
RESUMO
Background: This study aimed to evaluate the effect of two weeks oral administration of pomegranate seed extract (PGSE) on active and passive avoidance memories after permanent bilateral common carotid arteries occlusion (2CCAO) to induce permanent cerebral ischemia in adult female rats. Methods: Seventy adult female Wistar rats (250 ± 20 g) were used. Animals were divided randomly into seven groups with 10 in each: 1) Sham-operated; 2) Ischemic; 3–6) Ischemic received PGSE (100, 200, 400 and 800 mg/2mL/kg, orally) for 14 days; 7) Ischemic received vehicle. In order to create 2CCAO, carotid arteries were ligatured and then cut bilaterally. Active and passive avoidance task were measured using criterion condition responses (CCRs) in Y-maze and step-through latency (STL) in two-way shuttle box in all female rats. Results: Both active and passive avoidance memories were significantly impaired in rats after cerebral hypoxia-ischemia (CHI) (P < 0.001). PGSE treatment significantly improved passive and active memory impairments with 2CCAO (P < 0.05, P < 0.01, and P < 0.001). No toxicity was observed even with high-dose PGSE consumption (800 mg/kg, for 14 days). Conclusion: PGSE exhibits therapeutic potential for avoidance memories, which is most likely related at least in part to its antioxidative and free radical scavenging actions.
