ObjectiveTo evaluate the predictive value of the geriatric nutritional risk index (GNRI) for postoperative overall and severe complications after pancreaticoduodenectomy (PD) in the elderly patients with pancreatic cancer. MethodsThe clinical data of the elderly (65 years old or more) patients with pancreatic cancer underwent PD were retrospectively collected, who were admitted to the Fifth Affiliated Hospital of Xinjiang Medical University from January 2017 to October 2021. The incidences of postoperative overall and severe complications (Clavien-Dindo grade Ⅲ–Ⅴ was defined as severe complications) were summarized. The univariate and multivariate logistic regression models were used to analyze whether GNRI was a risk factor for overall and severe complications after PD. The area under the receiver operating characteristic curve (AUC) was used to evaluate the ability of GNRI to distinguish whether overall or severe complications occurred after PD and to confirm the optimal threshold. Then the patients were assigned into a high nutritional risk group (greater than the optimal threshold) and low nutritional risk group (the optimal threshold or less) based on this. Simultaneously, the clinical outcomes of the two groups were compared. ResultsIn this study, 190 elderly patients with pancreatic cancer were enrolled, 95(50.0%) of whom developed complications, including 28(29.5%) cases of serious complications. The results of multivariate logistic regression model analysis showed that the decreased GNRI was a risk factor for the occurrence of overall and severe complications after PD for the elderly patients [OR(95%CI)=0.361(0.154, 0.848), P=0.019; OR(95%CI)=0.906(0.834, 0.983), P=0.018]. The AUC of GNRI for assessing the occurrence of overall and severe complications was 0.765 and 0.715, respectively, with the optimal critical values of 98 and 96, respectively. Compared with the low nutritional risk group, the high nutritional risk group had higher postoperative total hospitalization costs (Z=–2.37, P=0.019), higher occurrences of overall complications (χ2=44.61, P<0.001) and severe complications (χ2=29.39, P＜0.001). ConclusionsIn elderly patients with pancreatic cancer underwent PD, incidence of serious complications is not lower. GNRI has a good discriminative value in terms of postoperative overall and severe complications. When preoperative GNRI is 98 or less and GNRI is 96 or less, patients should be given early preoperative nutritional support treatment in time.

【Abstract】ObjectiveTo determine the risk factors associated with development of pancreatic fistula after pancreatoduodenectomy (PD). Methods The clinical data of 123 consecutive patients who underwent PD from Dec. 1994 to Dec. 2003 were analysed retrospectively. Results The incidence of pancreatic fistula was 11.4% (14/123). Univariate analysis showed history of upper abdominal operation, texture of pancreas, postoperative serum hemoglobin level, type of pancreatojejunostomy and diameter of pancreatic duct were significantly associated with pancreatic fistula after PD. Multivariate analysis using Logistic regression identified four variables as independent factors associated with the occurrence of pancreatic fistula: history of upper abdominal operation, texture of pancreas, postoperative serum hemoglobin level and type of pancreatojejunostomy. Conclusion History of upper abdominal operation, soft texture of pancreas, postoperative serum hemoglobin level less than 90 g/L and routine invaginated pancreaticojejunostomy are main risk factors associated with development of pancreatic fistula after PD.
ObjectiveTo evaluate the various methods in prevention of pancreatic fistula after pancreaticoduodenectomy.MethodsThe literatures over the years related to prevention of pancreatic fistula were reviewed.ResultsManagement of the pancreatic stump following pancreaticoduodenectomy played the most important role in preventing pancreatic fistula. None of the methods of pancreatic stump had proved to be perfect in preventing pancreatic fistula, though pancreaticojejunostomy was the most widely practiced reconstruct strategy in varieties of option. For pancreaticojejunostomy and pancreaticogastrostomy, the rate of this complication was 12.3% and 11.1%,respectively. In recent years, a new procedure, bindingup pancreaticoduodenectomy, had shown a promise and excellent results in prevention of pancreatic fistula, the rate of fistula was 0 for consecutive 100 cases after pancreaticoduodenectomy.ConclusionBindingup pancreaticojejunostomy have a definite effect to avoid pancreatic fistula and be worthy of being recommended
【Abstract】ObjectiveTo investigate the relevant factors for fungal infection following pancreatoduodenectomy and offer the theoretical foundation for preventing the emergence of complications after operation． MethodsMedical records from 562 consecutive patients who underwent pancreatoduodenectomy in this hospital from 1995 to 2005 were retrospectively reviewed by using single factor and noncondition Logistic regression analyse. Results①Seventyeight patients (13.9%) developed invasive fungal infection. The most frequently isolated fungal were Candida albicans accounted for 67.0%， and followed by Candida glabrata, Candida papasilosis and Candida tropicalis and gastrointestinal tract was the most common infection site, followed by respiratory tract, abdominal cavity. ②Fungal infection occurred significantly more often in patients with the length of time in parenteral nutrition, antibiotic use or abdominal cavity complications. Conclusion The most common infection site and isolated fungal associated with pancreatoduodenectomy were gastrointestinal tract and Candida albicans. Abdominal cavity complications such as pancreatic fistula， biliary fistula and abdominal infection and extended use parenteral nutrition and antibiotic are the most important factors leading to invasive fungal infection after pancreatoduodenctomy. Eliminating the various risk factors will decrease the incidence of fungal infection.
ObjectiveTo investigate the occurrence and treatment of postoperative complications after laparoscopic laparoscopic pylorus-preserving pancreaticoduodenectomy (LPPPD) or pancreaticoduodenectomy (LPD). MethodThe clinical data of 130 patients undergoing LPD from October 2010 to December 2015 in West China Hospital of Sichuan University were analyzed retrospectively. ResultsOf 130 patients, postoperative complications occurred in 55 cases, including 24 cases of pancreatic fistula, 14 cases of gastric emptying disorder, 3 cases of anastomotic bleeding, 6 cases of peritoneal infection, 1 case of bile leakage, 1 case of venous thrombosis, 1 case of chylous leakage, 5 cases of peritoneal effusion, without the occurrence of stress ulcer and incision complications. There were significant difference in the incidence of pancreatic fistula (P=0.025), gastric emptying disorder (P=0.034), anastomotic bleeding (P=0.020), and peritoneal infection (P=0.016) among prophase group, metaphase group, and the later stage group. ConclusionsThe most common complication after LPD is pancreatic fistula. With the improvement of surgical techniques and procedures, incidences of some postoperative complications decreases gradually.
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.
