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.
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.
Objective To explore the clinical value of preoperative neoadjuvant chemotherapy (NAC) combined with laparoscopic pancreatoduodenectomy (LPD) with multiple surgical approaches in the treatment of borderline resectable pancreatic head cancer. Methods The clinicopathologic data of 35 patients with critical resectable pancreatic head carcinoma admitted to the Department of Hepatobiliary and Pancreatic Surgery of Luoyang Central Hospital Affiliated to Zhengzhou University and the Department of Hepatobiliary and Pancreatic Surgery of the Fifth Affiliated Hospital of Zhengzhou University from January 2017 to June 2022 were retrospectively analyzed. All patients received NAC before operation (AG protocol). At the end of the course of treatment, according to the type of borderline resectable pancreatic cancer (BRPC) [venous invasion type (BRPC-V type) and arterial invasion type (BRPC-A type)], take the individualized surgical approach for LPD (BRPC-V type: inferior mesenteric vein approach; BRPC-A type: left posterior approach, medial uncinate process approach, anterior approach, or lower mesocolon approach). The intraoperative condition, R0/R1 resection rate, lymph node dissection, postoperative complications, average hospital stay, recovery, follow-up and survival were recorded. Results① Efficacy evaluation of NAC: 13 patients were partially relieved , 17 patients were stable and 5 patients were progressive after 4 weeks of treatment. Five progressive patients continued to receive comprehensive internal medicine treatment, and the remaining 30 patients underwent LPD. ② Intraoperative situation: LPD were successfully completed in 30 patients, 2 patients underwent extended pancreaticoduodenectomy combined with superior mesenteric vein (or) portal vein reconstruction among them. Among the 30 patients with LPD, there were 10 cases of inferior mesenteric vein approach, 10 cases of left posterior approach, 6 cases of medial uncinate process approach, 1 case of left posterior approach+medial uncinate process approach, 2 cases of anterior approach, and 1 case of inferior mesocolon approach. The mean operative time was (379.4±77.3) min, the intraoperative blood loss was (436.9±95.1) mL. ③ Postoperative situation: The incidence rate of postoperative surgery-related complications was 33.3% (10/30), including 4 cases of Clavien-Dindo grade Ⅰ [biliary fistula in 1 case (3.3%), A-grade pancreatic fistula in 1 case (3.3%), gastric draining dysfunction in 1 case (3.3%), diarrhea in 1 case (3.3%)], 5 cases of grade Ⅱ [pulmonary infection in 2 cases (6.6%), B-grade pancreatic fistula in 2 cases (6.6%), abdominal infection in 1 case (3.3%)], and 1 case of grade Ⅲ [gastroduodenal artery stump bleeding (3.3%)]. Among the 10 patients with complications, 9 cases recovered after symptomatic treatment, and 1 case died, with a fatality rate of 3.3% (1/30). The mean postoperative hospital stay was (17.3±5.5) days. ④ Excision rate and pathological results: R0 resection rate was 90.0% (9/10) in 10 patients with BR-PV type LPD, and R1 resection was performed in 1 patient. R0 resection rate was 75.0% (15/20) in 20 patients with BR-A type, and R1 resection was performed in 5 patients (2 patients with medial uncinate process approach; Left posterior approach in 2 cases; Submesocolon approach was used in 1 case). In 30 patients with LPD, the total R0 removal rate was 80.0% (24/30), the number of lymph nodes dissected was (11±5). Pathological type: There were 26 cases (86.7%) of ductal adenocarcinoma in 30 patients, 1 case of adeno-squamous carcinoma (3.3%), 1 case of mucinous carcinoma (3.3%), 2 cases of acinocytic cell carcinoma (6.7%). 23 cases (76.7%) of medium-high differentiation and 5 cases (16.6%) of low differentiation, two cases (6.7%) were undifferentiated. ⑤ Postoperative follow-up and survival: 30 patients were completely followed-up for 6-39 months, with a median follow-up time of 17 months. The median survival time of BRPC-V and BRPC-A patients was 24.0 months and 17.0 months, respectively. The overall survival rates of 30 patients at 1, 2 and 3 years after operation were 77.3%、46.5% and 13.7%, respectively. Conclusion The selection of preoperative NAC combined with individualized surgical approach for patients with borderline resectable pancreatic head cancer is beneficial to improve the radical resection rate and clinical therapeutic effect, and has good clinical application value.
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.
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.
ObjectiveTo compare surgical safety and postoperative efficacy of total mesopancreas excision (TMpE) with pancreaticoduodenectomy (PD) and standard PD (Whipple).MethodsA total of 123 patients underwent PD in the Affiliated Hospital of Southwest Medical University from August 2013 to December 2017 were included, including 47 patients with pancreatic head carcinoma and 76 patients with periampullary carcinoma, then were divided into a TMpE group and a Whipple group respectively. The operative time, intraoperative blood loss, postoperative hospitalization time, postoperative recovery time of gastrointestinal function, postoperative complications, and postoperative survival of patients with the same site between the Whipple group and the TMpE group were retrospectively compared.Results① There were no significant differences in the baseline data between the TMpE group and the Whipple group in the pancreatic head carcinoma and periampullary carcinoma (P>0.05). ② For the patients with pancreatic head carcinoma, there were no significant differences in the operative time, postoperative hospitalization time, and postoperative gastrointestinal function recovery time between the TMpE group and the Whipple group (P>0.05), but the intraoperative blood loss in the TMpE group was significantly higher than that in the Whipple group (P=0.038); For the patients with periampullary carcinoma, the above indexes had no significant differences between the TMpE group and the Whipple group (P>0.05). ③ The total incidence of complications in the TMpE group was significantly higher than that in the Whipple group for the patients with pancreatic head carcinoma (χ2=6.595, P=0.010), which had no significant difference between the TMpE group and the Whipple group for the patients with periampullary carcinoma (P>0.05). ④ The cumulative survival curve in the TMpE group was better than that in the Whipple group for the patients with pancreatic head carcinoma (χ2=9.597, P=0.002), which had no significant difference between the TMpE group and the Whipple group for the patients with periampullary carcinoma (χ2=0.844, P=0.358).ConclusionsFor patients with pancreatic head cancer, comparing with standard Whipple, although TMpE PD increases intraoperative blood loss and overall incidence of complications, it could significantly improve long-term survival and there are no significant differences in postoperative recovery time and operative safety between Whipple and TMpE; For patients with periampullary carcinoma, there are no significant differences in surgical safety, long-term survival rate, and survival time between TMpE and Whipple.
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.
ObjectiveTo investigate the proportion of peripheral blood CD4+CD25+ regulatory T cells (Tregs) in patients with pancreatic head carcinoma, the dynamic changes of these cells before and after pancreatoduodenectomy were also analyzed. MethodsThe proportions of peripheral blood CD4+CD25+ Tregs in patients with pancreatic head carcinoma and normal individuals were examined by using flow cytometric analysis. The CD4+/CD8+ ratio was also studied before and after operation. ResultsThe patients with pancreatic head carcinoma showed higher ratio of CD4+CD25+ and CD4+CD25high Tregs compared with normal control before operation (Plt;0.05). However, the percentage of these T cells reduced significantly after pancreatoduodenectomy, which was most obviously on the 3rd day after operation (Plt;0.01, Plt;0.05). After operation, CA199 level began to decrease, which was obvious on the fourteen day after operation. This tendency of CD4+CD25high Tregs changes was similar to that of CA199. The patients showed an decreased ratios of CD4+/CD8+ compared with normal controls, which further declined after operation, and reached the lowest point on the seventh day after operation (Plt;0.05). ConclusionsPancreatoduodenectomy may be helpful for the recovery of antitumor immunity. The perioperative period of patients with pancreatic head carcinoma may be a beneficial windowphase for immune intervention and Tregs may be served as target cells.
