Introduction: In gallstone diseases, common bile duct stones and thickened bile could cause hepatitis or other difficulties. Therefore intraoperative cholangiography is helpful in many operations besides detecting and diagnosing the gallstones in common bile duct. Materials and Methods: Out of 266 patients who had undergone Laparoscopic Cholecystectomy surgery in GrandMed Hospital, 14 patients were found to have jaundice and cholestasis after undergoing laboratory and radiology tests. Results: These 14 patients have all undergone IOC. 7 out of 14 patients were found to have positive cholangiogram and the other 7 - negative. Biliary tract tumor and anatomic anomalies were not identified among these patients. Conclusion: Making analysis using only laboratory data is not adequate for directly detecting choledocholithiasis. IOC not only shows bile tract obstruction and determines cholestasis causes, but it also identifies the anatomy biliary tract, which is a procedure that facilitates dissection. Therefore IOCcan prevent the most serious complication of laparoscopic cholecystectomy - common bile duct injury. The sensitivity of IOC ensures the gathering of important information on time, so suggest to use it for every suspicious case.

Introduction: The complete blood count (CBC) is a frequently performed laboratory test today. This study evaluated the effects of temperature and sample storage time on parameters of CBC which could produce misleading results of clinical significance. Methods: In a cross-sectional study, CBC was checked in 20 randomly selected out-patients and baseline measurements were analyzed using the XN-2000 (Sysmex, Kobe, Japan) fully automated hematology analyzer. CBC was done all samples of storage at room temperature. Values were checked at time intervals of 0, 6, and 24 hr. Results: Among CBC parameters, white blood cell, red blood cell, hemoglobin, mean cell hemoglobin (MCH), neutrophils and lymphocytes were stable at time up to 6 h. Hematocrit increased between 0 and 24 hours, averaging 41.5% and 45.2%, respectively. MCV, RDW-SD, and RDW-CV increased between 0 and 24 hours. The mean value was statistically significant. There were 85.6fL/ 93.4fL (p<0.001), 40.7fL /48.2fL (p<0.001), 13.1% and 14.2% (p<0.05), respectively.
However, the MCHC was affected by time differences. (p <0.001 at 0 and 24 hours, p <0.001 at 3 and 24 hours). Platelet PDW, MPV, and P-LCR values increased between 0 and 24 h, respectively. Conclusion Whole blood samples were stored at room temperature for 24 hours for CBC tests, there were statistically significant differences in the size of red blood cells and platelets.
