Methods： Two hundred patients undergoing PD at our hospital between December 1996 and September 2002 were reviewed retrospectively. Standard PD was performed on 176 cases, standard PD with extended lymphadenectomy on 24 patients, whereas pylorus-preserving PD was not used. An end-toside combined with mucosa-to-mucosa pancreaticojejunostomy was performed on the patients with a hard pancreas and a dilated pancreatic duct, and a traditional end-to-end invagination pancreaticojejunostomy on the patients with a soft pancreas and a non-dilated duct. The risk factors with the potential to affect the incidence of complications were analyzed with SAS 8.12 software. Logistic regression was then used to determine the effect of multiple factors on early complications. Results： The overall rate of the major com- plications was 21% （42/200）, with the failure of pancreaticojejunal anastomosis being the most frequently encountered. Age （odds ratio [OR] 2.162）, diabetes mellitus （OR 4.086）, total serum bilirubin level （OR 7.556）, end-to-end pancreaticojejunostomy （OR 2.616）, T tube through the choledochojejunostomy （OR 0.100）, and blood transfusion over 1000 mL （OR 2.410） were the significant risk factors for the morbidity. Conclusion： The results from published series concerning morbidity after pancreaticoduodenectomy are not comparable because of lack of homogeneity between them. The knowledge of the complications rate in each particular department turns out essentially to provide the patient with tailored information about risks before surgery. Additionally, management of postoperative complications is essential for improving the results of this operation.展开更多

The hospitalization time, hospitalization costs, operation time, operative complications and post-operative liver functions of the two groups of patients were studied.RESULTS: The operation time and post-operative liver functions of the two groups of patients had no significant differences, while the hospitalization time, hospitalization costs and operative complications of the laparoscopic hepatic left lateral lobectomy combined with fiber choledochoscopic exploration in the common bile duct group were significantly lower than those in the traditional open operation group.CONCLUSION: For patients with gallstones in the left lobe of liver and in the common bile duct, laparoscopic hepatic left lateral lobectomy combined with fiber choledochoscopic exploration of the common bile duct can significantly shorten the hospitalization time, reduce the hospitalization costs and the post-operative complications,without prolonging the operation time and bringing about more liver function damages compared with traditional open operation. This kind of operation has more advantages than traditional open operation.展开更多

This could partly be attributed to the tighter legislation imposed by the government in these countries on detergents and other corrosive products and general public awareness. Most busy upper gastrointestinal surgical units in these countries, especially in the developed countries will only encounter a small number of cases per year. Up to date knowledge on the best management approach is lacking. In this article, we present our experience of two contrasting cases of corrosive injury to the upper gastrointestinal tract in our thoracic unit in the last 2 years and an up-to-date Medline literature search has been carried out to highlight the areas of controversies in the management of corrosive injuries of the upper gastrointestinal tract. We concluded that the main principle in managing such patients requires a good understanding of the pathophysiology of corrosive injury in order to plan both acute and future management. Each patient must be evaluated individually as the clinical picture varies widely. Signs and symptoms alone are an unreliable guide to injury.展开更多

The effect on circulating levels of antioxidants and indicators of oxidative stress, such as F2-isoprostane, was studied. RESULTS: The antioxidant enteral supplement showed no adverse effects and was well tolerated. After surgery a decrease in the circulating levels of antioxidant parameters was observed. Only selenium and glutamine levels were restored to pre-operative values one week after surgery. F2-isoprostane increased in the first three postoperative days only in the antioxidant supplemented group. Lipopolysaccharide binding protein (LBP) levels decreased faster in the antioxidant group after surgery.CONCLUSION: Despite lower antioxidant levels there was no increase in the circulating markers of oxidative stress on the first day after major abdominal surgery. The rise in F2-isoprostane in patients receiving the antioxidant supplement may be related to the conversion of antioxidants to oxidants which raises questions on antioxidant supplementation. Module AOX restored the postoperative decrease in selenium levels. The rapid decrease in LBP levels in the antioxidant group suggests a possible protective effect on gut wall integrity. Further studies are needed on the role of oxidative stress on outcome and the use of antioxidants in patients undergoing major abdominal surgery.展开更多

It is currently estimated that approximately one in every 350 children will experience severe symptomatic gastroesophageal reflux necessitating surgical treatment. Surgery for GORD is currently one of the common major operations performed in infants and children. Most of the studies found favour laparoscopic approach which has surpassed open antireflux surgery as the gold standard of surgical management for GORD.However, it must be interpreted with caution due to the limitation of the studies, especially the small number of subject included in these studies. This review reports the changing trends in the surgical treatment of GORD inchildren.展开更多

METHODS:The medical records of thirteen patients with pyogenic liver abscess who underwent surgical treatment between January 1995 and December 2002 were retrospectively reviewed to determine the clinical presentation, indication and nature of surgery, and out-come of surgery. RESULTS:The patients were predominantly women (10/13) with a mean age of 65 ± 17 years. Their main presenting symptoms were abdominal pain (100%) and fever (77%). The aetiologies included biliary (n = 6), cryptogenic (n = 3), portal (n = 2), and trauma (n = 2). Seven patients underwent percutaneous drainage as the initial treatment. Of these, three patients developed peritonitis secondary to peritoneal spillage. Another four patients failed to respond because of multilocula-tion. Salvage surgery was required in these patients. Six patients proceeded to straight laparotomy:two had marked sepsis and multiloculated abscess that precluded percutaneous drainage, and four presented with perito-nitis of uncertain pathology. Surgical procedures included deroofment and drainage (n = 9), liver resection (n = 3), peritoneal lavage (n = 2), cholecystectomy (n = 4), and exploration of common bile duct (n = 2). One patient required reoperation because of bleeding. Three patients required further percutaneous drainage after surgery. The overall mortality was 46%. Four patients died of multiorgan failure and two patients died of pulmonary embolism. CONCLUSION:Surgical treatment of pyogenic liver ab-scess is occasionally needed when percutaneous drainage has failed due to various reasons. Mortality rate in this group of patients has remained high.展开更多

METHODS： From January 1987 to March 2003, 140 patients with adenocarcinoma of the cardia underwent resection in the authors＇ institution. They were divided into three groups with regard to age. Patients 〈70 and 〉 60 year old （31） were excluded; we also excluded 18 out of 109 patients with poor general status or systemic metastases. So, we compared 51 elderly （≥ 70 year old） and 58 younger patients （≤ 60 year old）. The treatment was esophagectomy for type I tumors, and extended gastrectomy and distal esophagectomy for type Ⅱ and Ⅲ lesions. RESULTS： Laparotomy was carried out in 91 patients （83.4%）, 38 in the elderly （74.5%） and 53 in younger patients （91.3%, P〈0.05）. Primary resection was performed in 81 cases （89%） without significant differences between the two groups. Postoperative death was higher in the elderly （12.1%） than the other group （4.1%, P〈0.05）, while morbidity was similar in both groups. A curative resection （R0） was performed in 59 patients （72.8%）, 69.6% in the elderly and 75% in the younger group （P〉0.05）. The overall 3- and 5-year survival rates were 26.7% and 17.8% respectively for the elderly and 40.7% and 35.1% respectively for younger patients （P = 0.1544）. Survival rates were significantly associated with R0 resection, pathological node-poskive category and tumor differentiation in both groups.CONCLUSION： As the age of the general population increases, more elderly patients with gastric cardia cancer will be candidates for surgical resection. Age alone should not preclude surgical treatment in elderly patients with gastric cardia cancer and a tumor resection can be carried out safely. Certainly, we should take care in defining the surgical treatment in elderly patients, particularly as regarding the surgical approach; although the surgical approach does not influence the survival rate, the transhiatal way still remains the best one due, to the lower incidence of respiratory morbidity and thoracic pain.展开更多

It is often an incidental finding and can be found at different sites in the gastrointestinal tract. It may become clinically evident when complicated by pathologic changes such as inflammation, bleeding, obstruction, and malignant transformation. In this report, a 40 years old woman with epigastric pain due to ectopic pancreatic tissue in the stomach is described. The difficulty of making an ac- curate diagnosis is highlighted. The patient has remained free of symptoms since she underwent wedge resection of the lesion three years ago. Frozen sections may help in deciding the extent of resection intraoperatively. Al- though ectopic pancreas is rare, it should be considered in the differential diagnosis of a submucosal gastric tumour.展开更多
