ObjectiveTo evaluate the imaging examination in the diagnosis of periampullary carcinoma. MethodsA retrospective analysis of 125 patients with pathologically proven periampullary carcinomas enrolled in Zhongshan hospital between Jan. 1991 and Dec. 2000. ResultsThe accuracy of BUS or CT was higher than that of ERCP in patients with pancreatic head carcinoma (P=0.044,P=0.029, respectively). The accuracy of ERCP was higher than that of BUS or CT in patients with duodenal papillary carcinoma (P=0.005,P=0.03, respectively). The accuracy of ERCP was higher than that of BUS or CT in patients with ampullary carcinoma (P=0.157,P=0.282, respectively). The accurary of MRCP was 8/8,8/9 respectively in patients with duodenal papillary carcinoma and ampullary carcinoma. ConclusionBUS+CT is the manner of choice in the diagnosis of pancreatic head carcinoma, ERCP is suitable for nonpancreatic periampullary cancer. MRCP should be applied widely in the near future.
ObjectiveTo assess the value of palliative surgical treatment for patients with advanced periampullary carcinoma. MethodsThe clinical data of 292 cases of unresectably advanced periampullary carcinoma who had undergone palliative surgical treatment between June 1998 and June 2008 were analyzed retrospectively. ResultsThe mortality and incidence of complications after operation were 0.7% (2/292) and 24.0% (70/292), respectively. The average survival time was 10.3 months (range 4－29 months). Total bilirubin decreased to normal in 243 cases (83.2%) and decreased by 50% in 39 cases (13.4%) after operation. The totally effective rate was 96.6% (282/292). ConclusionsPalliative surgical treatment is a safe method for the patients with unresectably advanced periampullary carcinoma. Hepaticojejunostomy combined with gastrojejunostomy is recommended for these patients.
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.
【Abstract】Objective To investigate the detection and significance of micrometastasis in lymph nodes of periampullary carcinoma. MethodsThe immunoreactivity of CK19, CK7 and CK18 in 220 lymph nodes from 60 patients who had been carried out radical resection of periampullary carcinoma were revealed by immunohistochemical method. Combining with clinical data and the followup result discussion and analysis were made. All the lymph nodes collected from January 1997 to August 2004 in this hospital were examined to be nonlymphonodus metastasis by histological HE stain. The criterion of positive CK was established and micrometastasis will be diagnosed if CKs revealed to be positive combining with the morphological changes of lymph node tissue through the observation of microscope. ResultsFortythree of 220 lymph nodes of periampullary carcinoma had been micro metastasized. The detection rates of micrometastasis were 19.55%（43/220）， 14.55%（32/220）and 11.36%（25/220） with CK19，CK7 and CK18 antibody, respectively, which meant that CK19 were better than CK18 for detection of micrometastasis. Detection rates of CK7， CK19 were higher in Ⅲ， Ⅳ stage than inⅠ， Ⅱ（P＜0.05）, whereas it had no relationship with gender, age and tumor differentiation degree. The oneyear survival rate for micrometastasis patients was lower than nonmicrometastasis patients’ (P＜0.05). Conclusion Micrometastasis of periampullary carcinoma may be the early stage of tumor metastasia. The CK antibodies are significant levels to detect micrometastasis of periampullary carcinoma and to guide the clinical treatment and prognostic judgment.
Objective To summarize preliminary experience of laparoscopic pancreaticoduodenectomy for periampullary carcinoma. Method The clinical data of patients with periampullary carcinoma underwent laparoscopic pancreaticoduodenectomy from July 2016 to September 2016 in the Shengjing Hospital of China Medical University were analyzed retrospectively. Results Two patients underwent complete laparoscopic pancreaticoduodenectomy, 2 patients underwent laparoscopic resection and anastomosis assisted with small incision open. The R0 resection and duct to mucosa pancreaticojejunal anastomosis were performed in all the patients. The operative time was 510–600 min, intraoperative blood loss was 400–600 mL, postoperative hospitalization time was 15–21d, postoperative ambulation time was 6–7 d. Three cases of pancreatic fistula were grade A and all were cured by conservation. No postoperative bleeding, delayed gastric emptying, intra-abdominal infection, and bile leakage occurred. The postoperative pathological results showed that there was 1 case of pancreatic head ductal adenocarcinoma, 1 case of cyst adenocarcinoma of pancreas uncinate process, 1 case of papillary carcinoma of duodenum, and 1 case of terminal bile duct carcinoma. Conclusion The preliminary results of limited cases in this study show that laparoscopic pancreaticoduodenectomy has been proven to be a safe procedure, it could reduce perioperative cardiopulmonary complications, its exhaust time, feeding time, and postoperative ambulation time are shorter, but its operative complications could not be reduced.
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 summarize the research status and progress of imaging diagnosis of periampullary carcinoma. Methods The literatures on imaging diagnosis of periampullary carcinoma were reviewed. Results At present, the commonly used imaging diagnosis methods for periampullary carcinoma mainly include ultrasound, CT, MRI, and endoscopic retrograde cholangiopancreatography. Some other new imaging techniques had also been applied in the diagnosis and evaluation of periampullary carcinoma. Conclusions Different imaging methods have their own advantages and disadvantages in the diagnosis of periampullary carcinoma. Therefore, the detection rate and diagnostic accuracy of periampullary carcinoma can be improved by rational selection of imaging techniques or combined application of multiple techniques.
