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.
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。
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.
ObjectiveTo explore value of preoperative neutrophil-to-lymphocyte ratio (NLR) combined with carbohydrate antigen 19-9 (CA19-9) in evaluating prognosis for patients with pancreatic head carcinoma.MethodsThe clinical data of patients with pancreatic head carcinoma underwent radical pancreaticoduodenectomy in the Lanzhou University Second Hospital from February 2011 to August 2017 were retrospectively analyzed. The preoperative serum albumin (ALB), CA19-9, NLR, carcino-embryonic antigen (CEA), alpha-fetoprotein (AFP), N stage, tumor differentiated degree, and other indicators were recorded and the patient’s overall survival was recorded. Linear correlation analysis was used to examine the association of NLR with serum CA19-9. The receiver operating characteristic (ROC) curve was used to calculate the cutoff values of NLR and CA19-9 corresponding to the overall survival rate of 2-year. Kaplan-Meier method was used for survival analysis. Cox proportional hazards regression model was used to evaluate the prognostic value of preoperative CA19-9 and NLR.Results① A total of 121 patients were enrolled in this study. There was no significant correlation between the preoperative serum CA19-9 and NLR (r=0.100 05, P=0.272 9). ② Multivariate analysis showed that higher NLR, higher CA19-9 level, higher N stage, and lower tumor differentiation were the risk factors for overall survival of pancreatic head carcinoma (P<0.05). ③ The cutoff values of CA19-9 and NLR in evaluating the 2-year overall survival rate were 123.3 U/mL and 2.34 respectively by the ROC curve analysis, the area under ROC curve of CA19-9, NLR, and CA19-9 combined with NLR were 0.763, 0.686, and 0.823, respectively. ④ The proportions of patients with CEA≥5 μg/L and ≥N1 stage were higher in the patients with CA19-9≥123.3 U/mL as compared with patients with CA19-9<123.3 U/mL (P<0.05); The proportions of patients with preoperative serum ALB level <35 g/L and CEA≥5 μg/L, ≥N1 stage, and poor differentiation were higher in the patients with NLR≥2.34 as compared with the patients with NLR<2.34 (P<0.05). ⑤ Kaplan-Meier survival analysis showed that patients with CA19-9≥123.3 U/mL and NLR≥2.34 had worse overall survival than those patients with CA19-9<123.3 U/mL and NLR<2.34 (HR=3.599, P<0.01; HR=2.506, P<0.01). The patients with CA19-9≥123.3 U/mL and NLR≥2.34 (n=42), CA19-9≥123.3 U/mL or NLR≥2.34 (n=48), CA19-9<123.3 U/mL and NLR<2.34 (n=31) had better overall survival in turn (overall and between groups, all P<0.01).ConclusionPreoperative serum CA19-9 combined with NLR has an important value in evaluating prognosis for patients with pancreatic head carcinoma.
【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.
Objective To explore the clinical therapeutic value of pancreatoduodenectomy in patients with carcinoma of ampulla of Vater (AVC). Methods The clinical data of 195 patients with AVC between March 1995 and March 2009 in this hospital were analyzed retrospectively. All the patients were divided into non-surgery group (n＝51), palliative surgery group (n＝96), and resection group (n＝48) according to the treatment methods. Results The 1-year, 3-year, and 5-year survival rates in the resection group were higher than those in the non-surgery group and the palliative surgery group (Plt;0.01). However, the incidence of complications in the resection group was higher than that in the nonsurgery group or the palliative surgery group (Plt;0.05). The radical resection rates, 1-year, 3-year, and 5-year survival rates of carcinomas of head of pancreas were significantly lower than those of carcinomas of the terminal of common bile duct or carcinomas of duodenal papilla (Plt;0.05, Plt;0.01). There was no significant difference of the perioperative mortality, complications rate, 1-year, 3-year, or 5-year survival rate between preoperative drainage jaundice group and preoperative nondrainage jaundice group (Pgt;0.05). The perioperative mortality in the resection group above the age of 70 years old was higher than that of less than or equal to 70 years old （Plt;0.05）. Compared with the non-surgery group or palliative surgery group, there were significant increasement of the incidence of serious or deadly perioperative complications in the resection group (Plt;0.05). Conclusions Surgical resection remains one of the most important measures of the treatment of AVC, in particular, the radical pancreatoduodenectomy is the only effect way for AVC, thus significantly prolonging the patient’s postoperative survivals and significantly improving the qualities of life.
Objective To summary the clinical effect of a special method of vascular reconstruction in pancreaticoduodenectomy (PD) combined with portal vein (PV) and superior mesenteric vein (SMV)/spleen vein(SV) confluence resection in the treatment of pancreatic head cancer with PV and SMV/SV confluence were both invaded by tumor. Methods Retrospectively summarized the clinical data of 1 pancreatic head cancer patient who got treatment at Shanghai General Hospital in March 2017, whose PV and SMV/SV confluence were both invaded by tumor. According to the preoperative CT judgement, the degree of tumor and vascular infiltration was determined as type of Loyer E, the invasion part was located on the right wall of the SMV/SV confluence, and the depth of infiltration did not exceed the lowest point of the SMV/SV confluence junction. This patient underwent PD combined with the invasion of the PV and the right part of SMV/SV confluence resection, with the left part of SMV/SV confluence was retained, and then vascular graft was used for the anastomosis between the PV and the SMV/SV confluence. Results The patient’s operative time was 380 min, and the blood loss was 200 mL. The blocking time of PV, SMV, and SV was 35, 30, and 30 min, respectively, without postoperative pancreatic fistula, biliary leakage, incision infection, pulmonary infection, vascular graft infection, blood clots, liver failure, and other complications. The patient recovered and discharged from hospital on postoperative twelfth day. In postoperative 1-month, the patient reviewed on abdomen CT angiography (CTA), showing the vascular graft unobstructed. In postoperative 3-, 6-, 9-, and 12-month, there was no obvious discomfort, and chest and abdominal CT found no tumor recurrence and metastasis in postoperative 12-months, as well as liver function was normal. Conclusions For pancreatic head cancer with PV and SMV/SV confluence are both invaded by tumor, PD combined with the invasion of the PV and the right part of SMV/SV confluence resection, then the left part of SMV/SV confluence and PV are anastomosed by vascular graft, this is a special method of vascular reconstruction. It can reduce SV to reconstruct the anastomosis separately, shorten PV blocking time and the liver ischemia time, so it is very important in the rapid recovery of the liver function.
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.
