In the treatment of patients with symptomatic cholelithiasis and choledocholithiasis (CBDS) detected during intraoperative cholangiography (IOC),or when the preoperative study of a patient at intermediate risk for CBDS cannot be completed due to the lack of imaging techniques required for confirmation,or if they are available and yield contradictory radiological and clinical results,patients can be treated using intraoperative endoscopic retrograde cholangiopancreatography (ERCP) during the laparoscopic treatment or postoperative ERCP if the IOC finds *** choice of treatment depends on the level of experience and availability of each option at each *** ERCP has the advantage of being a single-stage treatment and has a significant success rate,an easy learning curve,low morbidity involving a shorter hospital stay and lower costs than the two-stage treatments (postoperative and preoperative ERCP).Intraoperative ERCP is also a good salvage treatment when preoperative ERCP fails or when total laparoscopic management also fails.

AIM： To investigate the intestinal anti-inflammatory effect and mechanism of a probiotic Lactobacillus salivarius ssp. salivariusCECT5713 in the TNBS model of rat colitis. METHODS： Female Wistar rats （180-200 g） were used in this study. A group of rats were administered orally the probiotic L. salivarius ssp. salivarius （5 × 10^8 CFU suspended in 0.5 mL of skimmed milk） daily for 3 wk. Two additional groups were used for reference, a non-colitic and a control colitic without probiotic treatment, which received orally the vehicle used to administer the probiotic. Two weeks after starting the experiment, the rats were rendered colitic by intracolonic administration of 10 mg of TNBS dissolved in 0.25 mL of 500 mL/L ethanol. One week after colitis induction, all animals were killed and colonic damage was evaluated both histologically and biochemically. The biochemical studies performed in colonic homogenates include determination of myeloperoxidase （MPO） activity, glutathione （GSH） content, leukotriene B4 （LTB4） and tumor necrosis factor α （TNF-α） levels, as well as inducible nitric oxide synthase （iNOS） expression. In addition, the luminal contents obtained from colonic samples were used for microbiological studies, in order to determine Lactobacilli and Bifidobacteria counts. RESULTS： Treatment of colitic rats with L. salivarius ssp. salivarius resulted in amelioration of the inflammatory response in colitic rats, when compared with the corresponding control group without probiotic treatment. This antiinflammatory effect was evidenced macroscopically by a significant reduction in the extent of colonic necrosis and/or inflammation induced by the administration of TNBS/ethanol （2.3±0.4 cm vs3.4±0.3 cm in control group, P〈0.01） and histologically by improvement of the colonic architecture associated with a reduction in the neutrophil infiltrate in comparison with non-treated colitic rats. The latter was confirmed biochemically by a significant reduction of colonic MPO ac
