ObjectiveTo explore the prognostic factors of malignant tumors in ampulla, lower bile duct, head of pancreas, uncinate process, and neck of pancreas after operation.MethodThe recent literatures on malignant tumors in this region at home and abroad were summarized.ResultsThe prognosis of five groups of malignant tumors in ampulla, lower bile duct, head of pancreas, uncinate process, and neck of pancreas was correlated with their origin, growth site, tumor diameter, nerve invasion, vascular invasion, lymphatic metastasis, pathological and histological classification, and cutting edge status. The different location and pathological classification of tumors made the different neurovascular invasion rate, lymphatic metastasis rate, and R0 resection rate.ConclusionsBy summarizing and analyzing the origin, growth site, diameter, nerve invasion, vascular invasion, lymphatic metastasis, pathological and histological classification, and cutting edge status of tumors, we can improve the clinical prediction of tumors in this region, select appropriate surgical methods before operation, and formulate more reasonable adjuvant treatment plan after operation, in order to improve the pertinence of the treatment of tumors in this region, improve the prediction, and finally better serve the clinical work.
Objective To determine the safety and efficacy of surgical biliary bypass on the elderly patients with unresectable pancreatic head cancer. Methods The clinical data of 55 cases with unresectable pancreatic head cancer treated with palliation methods from July 2002 to June 2009 in our hospital were retrospectively analyzed. The patients were divided into three groups according to different age and therapeutic program: Nineteen patients, 65 years of age or older, were managed with surgical biliary bypass (group A), 19 patients under 65 years of age were treated by surgical biliary bypass (group B) and 17 patients with the age of 65 years or older received percutaneous transhepatic biliary drainage (group C). Then the therapeutic results were compared.Results With respect to the postoperative level of serum bilirubin, the incidence of early complications, postoperative hospitalization and mean survival time, no statistically significant difference was found between group A and B (Pgt;0.05). There was one case of recurrent jaundice and one case of gastric output obstruction in group B, while no one suffered postoperative complication in group A, and the difference was statistically significant (Plt;0.01). Compared with group A, the postoperative level of serum bilirubin, the number of patient readmitted, the rate of recurrent jaundice and gastric output obstruction were higher in group C (Plt;0.05 or Plt;0.01). The mean postoperative hospitalization and overall survival time were significantly shorter in group C than group A (Plt;0.05 or Plt;0.01, respectively). Conclusion Surgical palliation does not increase the morbidity rate, but it does improve the quality of life in elderly patients with unresectable pancreatic head cancer.
目的 探讨螺旋CT双期薄层增强扫描对胰头癌可切除性的评估价值。方法 回顾性分析24例经螺旋CT双期薄层增强扫描胰头癌的CT表现，观察肿块对邻近器官或组织侵犯情况，以及有无远处器官和淋巴结转移，据此判断肿块能否切除，并将其结果与手术病理结果相对照。结果 螺旋CT判断胰头癌可切除的敏感性为90.9%，特异性为84.6%，阳性预测值为83.3%，阴性预测值为91.7%，准确性为87.5%。结论 螺旋CT双期薄层增强扫描判断胰头癌可切除性的价值较高，对外科医生选择最佳治疗方案有较大的帮助。
Sixteen cases unresectable carcinoma of the head of the pancreas complicated with jaundice were treated by one stage cholecysto-jejunal and gastro-jejunal loop double anastomosis, the same result of jaundice drainage and prevention of bile reflux were obtained when compared with simple cholecysto-jejunal loop anastomosis, on the other hand, the obstructive symptoms resulting from postoperative cancerous comppression of duodenum and pylorus were avoided as well. The operation is simple with less physiologic disturbance and the patient can lead better postoperative live.
目的探讨如何减少胰十二指肠切除术后并发症及提高胰头及壶腹周围癌的疗效。方法总结我院41例胰头及壶腹周围癌患者行胰十二指肠切除术治疗的经验。结果癌肿切除率为17.7%，手术并发症发生率为26.8%，手术死亡率为14.6%。而1990年后仅发生2例且无胆、胰瘘发生，亦无死亡。结论应用胰肠、胆肠吻合口处双管减压引流，防止了术后胰、胆瘘的发生，是降低并发症及死亡率的重要手段。
Forty-five pancreatoduodenectomies had been performed in our hospital from 1981 to 1994, of which 35 cases were diagnosed as carcinomas of Vater’s ampulla or pancreatic head, and 10 (cases) as benign lesions. Through analysis of misdiagnosed cases, the authors emphasize that it is important to take correct history of jaundiced patients in detail according to the character of the jaundice and associated symptoms before any operation done. Secondly, all clinical materials must be thoroughly collected and special examinations for diagnosis should be chosen scientifically to avoid relying only on one sort of examination result as diagnostic standard. Thirdly, during operation the area of pancreatic head should be explored carefully and any lesions in doubt should be examined pathologically by puncture biopsy and frozen section to avoid misdiagnosis and thus performing pancreatoduodenectomy.
【Abstract】 Objective To summarize the experience in radical excision of carcinoma of head of pancreas in order to improve the surgical skills and reduce the occurrence of postoperative complications. Methods The clinical material of 55 patients (ages: 32-72 years; mean age: 56.5 years) with carcinoma of head of pancreas who received radical excision from January 1996 to March 2005 were analyzed retrospectively. All the cases were pathologically verified as ductal adenocarcinoma of head of pancreas. The treatment time following the operations was divided into two phases by year 2002 ( phaseⅠ: 1996-2002; phaseⅡ: 2002-2005). Different surgical treatment groups were fixed and ICU and other measures were implemented during the second phase. Results All the patients, consisting of 31 males and 24 females, underwent consecutive extended resection. The radically curative rates of phaseⅠand phaseⅡ were 25.9%(29/112) and 34.7%(26/75), respectively, and the complication rates were 48.3%（14/29） and 19.2%（5/26）, respectively. A variety of surgical skills would improve the operation, including extended regional lymphadenectomy, resection of involved nerve plexus, combined vessel resection and comprehensive bleeding-control technique and so on. Conclusion The improvement of radically curative effect and the reduction of complication rate depend on the advancement of surgical skills and the further understanding of pathophysiology of carcinoma of head of pancreas.
ObjectiveTo compare the efficacy between laparoscopic pancreaticoduodenectomy (LPD) and open pancreaticoduodenectomy (OPD) in treatment of carcinoma of head of pancreas. MethodsClinical data of 60 patients with locally advanced carcinoma of head of pancreas who underwent pancreaticoduodenectomy in our hospital from October 2004 to October 2009 were collected, of which 26 patients were in LPD group and 34 patients were in OPD group. ResultsOperative time and hospitalization expense of patients in LPD group were both longer or more than those of OPD group (P<0.05), but blood loss, time of starting activity, time of aeration, time of pulling out the drainage tube, time of pulling out the stomach tube, time of absolute resting on bed, and hospitalization time in LPD group were all shorter or lower than those of OPD group (P<0.05). There were 25 patients suffered with postoperative complications, including 10 patients in LPD group and 15 patients in OPD group, and there was no significant difference between the 2 groups in total incidence of postoperative complication (P>0.05). But in the specific postoperative complication, the incidences of pancreatic fistula and biliary fistula of LPD group were higher than those of OPD group (P<0.05), but incidences of incision infection, pulmonary infection, and systemic infection were all lower than those of OPD group (P<0.05). All patients were followed up for 1-60 months with the median time of 21.5 months. During the follow-up period, in LPD group, 24 patients suffered with recurrence, 20 patients suffered with tumor metastasis, and 24 patients died; in LPD group, 31 patients suffered with recurrence, 25 patients suffered with tumor metastasis, and 31 patients died. There were no significant difference between the 2 groups in the recurrence rate, metastasis rate, mortality, and survival situation (P>0.05). ConclusionsFor carcinoma of head of pancreas, postoperative recovery and infection complications of LPD are significantly superior than those of OPD. But compared with the OPD, it has no obvious advantage in reducing the pancreatic fistula, biliary fistula, delayed gastric emptying, and other complications, and it also has no obvious advantage in improving the long-term survival situation too.
