Disappearance and appearance of an indigestible marker in feces from growing pigs as affected by previous-and currentdiet composition

Journal of Animal Science and Biotechnology 2017年第3期8卷 643-651页

Background： Indigestible markers are commonly utilized in digestion studies, but the complete disappearance or maximum appearance of a marker in feces can be affected by diet composition, feed intake, or an animal＇s *** objectives of this study were to determine the impact of previous（Phase 1, P1） and current-（Phase 2, P2）diet composition on marker disappearance（Cr） and appearance（Ti） in pigs fed 3 diets differing in NDF ***： When pigs were maintained on the 25.1, 72.5, and 125.0 g/kg NDF diets, it took 5.1, 4.1, and 2.5 d, respectively,for Cr levels to decrease below the limit of quantitation; or 4.6, 3.7, or 2.8 d, respectively, for Ti to be maximized. These effects were not, however, independent of the previous diet as indicated by the interaction between P1 and P2 diets on fecal marker concentrations（P 〈 0.01）. When dietary NDF increased from P1 to P2, it took less time for fecal Cr to decrease or fecal Ti to be maximized（an average of 2.5 d）, than if NDF decreased from P1 to P2 where it took longer for fecal Cr to decrease or fecal Ti to be maximized（an average of 3.4 d）.Conclusions： Because of the wide range in excretion times reported in the literature and improved laboratory methods for elemental detection, the data suggests that caution must be taken in considering dietary fiber concentrations of the past and currently fed diets so that no previous dietary marker addition remains in the digestive tract or feces such that a smal amount of maker is present to confound subsequent experimental results, and that marker concentration have stabilized when these samples are col ected.

Total laparoscopic removal of accessory gallbladder:A case report and review of literature

引用

世界胃肠外科杂志：英文版（电子版） 2015年第12期7卷 398-402页

作者： Yaniv Cozacov Gokulakkrishna Subhas Michael jacobs Janak Parikh Department of Surgery Providence Hospital and Medical Centers

Accessory gallbladder is a rare congenital anomaly occurring in 1 in 4000 births, that is not associated with any specific symptoms. Usually this cannot be diagnosed on ultrasonography and hence they are usually not diagnosed preoperatively. Removal of the accessory gallbladder is necessary to avoid recurrence of symptoms. h-type accessory gallbladder is a rare anomaly. Once identified intra-operatively during laparoscopic cholecystectomy, the surgery is usually converted to open. By using the main gallbladder for liver traction and doing a dome down technique for the accessory gallbladder, we were able to perform the double cholecystectomy with intra-operative cholangiogram laparoscopically. Laparoscopic cholecystectomy was performed in 27-year-old male for biliary colic. Prior imaging with computer tomography-scan and ultrasound did not show a duplicated gallbladder. Intraoperatively after ligation of cystic artery and duct an additional structure was seen on its medial aspect. Intraoperative cholangiogram confirmed the patency of intra-hepatic and extra-hepatic biliary ducts. Subsequent dissection around this structure revealed a second gallbladder with cystic duct(h-type). Pathological analysis confirmed the presence of two gallbladders with features of chronic cholecystitis. It is important to use cholangiogram to identify structural anomalies and avoid complications.
