| Backgroundlaparoscopic cholecystectomy have became the gold standard of laparoscopicoperation, for its advantages of tiny wound, effective results, less pain, rapid functional recovery, rapid healing with minute cicatricle, shorter length of stay and the satisfied psychological effects for patients. However, some complication of laparoscopic cholecystectomy always disturb both clinician and patients. It is fatal to injury the inner blood vessel of the gallbladder bed and cause CO2 air embolus. It is also the main reason for opening the abdomen of a patient again.At the beginning of laparoscopic cholecystectomy, blood vessel variation in gallbladder bed and adjoining structures have been observed by clinicians, and it was regarded as the main reason for heavily hemorrhage and the second operation. For old anatomic method, study was dedicated to only the distribution of vessels in the gallbladder bed. No comparing with the data of ultrasonic image and no guiding of it to ultrasound observation were even concerned. Despite of the observation for variant vessels in the gallbladder bed under the clinical ultrasound, the relationship between those vessels and the gallbladder bed were never been described.It is difficult to describe the position and relationship of those variant vessels accurately. Therefore, we wish to adopt different ways on the same sample, including ultrasound observation, anatomic dissection, and the cast sample survey to elucidate the position and relationship of those variant vessels, and provide supports for clinical application. It will be valuable to identify variant vessels in the gallbladder bed... |
