1.The sphincter of Oddi: from incision to repair
Journal of Clinical Hepatology 2017;33(2):209-212
The sphincter of Oddi is a valve that controls the biliopancreatic duct and plays an irreplaceable role in maintaining normal physiological functions of the biliopancreatic duct.However,sphincteroplasty and sphincterotomy may cause varying degrees of damage to the function of the sphincter of Oddi,which may further result in postoperative reflux of duodenal fluids and bacterial contamination in bile and increase the risks of recurrent common bile duct stones,reflux cholangitis,and even cholangiocarcinoma.Therefore,clinical physicians should protect the structure and function of the sphincter of Oddi.Based on our experience,under the premise that the extrahepatic bile duct can be preserved,patients with iatrogenic injury of the sphincter of Oddi can be treated with transduodenal sphincteroplasty to restore the structural integrity of the sphincter of Oddi and reduce biliopancreatic duct complications secondary to loss of function.

Optimization of surgical treatment of biliary dilatation (BD) depends on reasonable clinical classification and standardized classification-based treatment strategy.Due to increasing limits and defects of classic Todani classification,a new classification named Dong-classification has been proposed,which was based on a large series analysis from a single referral center.Some important parameters including anatomical location and range of BD,pathogenic factors,and different surgical managements were main considerations in the new classification.After practical application and evaluation,Dong-classification has been improved step by step.It is believed that Dong-classification may contribute to improving surgical treatment decision and selecting reasonable operative plan.

Objective To explore the diagnosis and treatment for pancreatic cystic neoplasms.Methods The clinical data of 10 cases with pancrestic cystic neoplasms treated from 2004 to 2008 was reviewed and both domestic and internal pertinent literatures were summarized.Results The pancreatic cystic neoplasms mostly happened in middle-aged women.The clinical manifestations showed no specificity.Ultrasonography, CT and MRI could offer important sign for diagnosis.The rate of surgical resection was high and the prognosis was satis-factory.Conclusions The pancreatic cystic neoplasms is being muh with the development of imagings.It is dif-ficuh to distinguish the feature of the cystic neoplasms before surgery, so surgerical resection should be done for all cystic tumors found.

Objective To explore the reasons and preventive measures for the postoperative complications of hilar cholangiocarcinoma.Methods The clinical features,diagnosis,surgical therapy,postoperative complications and follow-up result were retrospectively analyzed on 89 cases of hilar cholangiocarcinoma admitted into our hospital from January 2008 to September 2014.Surgical approach:47 cases of radical resection including hepatoduodenal ligament skeletonized resection in 18 cases; concurrent partial hepatectomy in 29 cases,palliative resection in 17 cases,biliary tract drainage in 25 cases.There were 6 cases receiving partial portal vein resection and reconstruction.Results Among 89 patients there were 93 postoperative complications.Biliary complications developed in 22 cases (24.7%,22/89) including bile leakage in 13 cases (14.6%),biliary tract infection in 7 cases,anastomotic stricture in 2 cases.Wound infection in 19 cases,lung infection in 4 cases,ascites in 31 cases,pleural effusion in 10 cases,liver abscess in 1 case,intraabdominal bleeding in 2 cases,postoperative gastrointestinal bleeding,intestinal fistula,liver failure and multiple organ failure (MODS) developed in one each cases.One case died of MODS with the mortality of 1.1%.Conclusions Postoperative complications were common in hilar cholangiocarcinoma combined liver resection and/or vascular resection and reconstruction.Bile leakage is the most frequently seen necessitating long term proper drainage.

BACKGROUND: With the advancements in helical CT myelography and computer image postprocessing, virtual medical imaging has acquired good outcomes in the diagnosis and treatment of complex cervical spondylosis. OBJECTIVE: To observe the effects and significance of helical CT myelography on multiplanar and three-dimensional reconstruction of virtual anatomical models of cervical spondylosis. DESIGN, TIME AND SETTING: The present computer three-dimensional reconstruction, gold standard control study was performed at the Second Hospital Affiliated to Soochow University between January 2001 and January 2006. PARTICIPANTS: Twenty patients with complex cervical spondylosis, who had received surgery, were employed for this study. METHODS: Virtual anatomical model of cervical spondylosis was established by multiplanar and three-dimensional reconstruction through the use of helical CT myelography in 20 patients. Scanning and reconstruction results were used for pre-surgery disease condition evaluation and virtual surgery. In addition, surgical intuitionistic results were considered gold standard to evaluate the accuracy and efficacy of virtual anatomical models. MAIN OUTCOME MEASURES: The accuracy and efficacy of virtual anatomical models. RESULTS: Virtual anatomical models could concurrently show bony and membranate vertebral canals. These exhibited comprehensive and minute bony anatomic structure of cervical vertebrae and anatomic information regarding dura mater, spinal cord, and nerve sleeve for pre-surgery evaluation and virtual surgery. The imaging virtual anatomic information was in accordance with practical anatomical information in patients. CONCLUSION: Virtual anatomical model can be used to comprehensively evaluate the disease condition of cervical spondylosis and simulate the surgery due to its intuitionistic, vivid, and accurate display of anatomy of cervical vertebrae.
