Objective To investigate safety and therapeutic effect of total pancreatectomy plus splenectomy for patient with pancreatic cancer. Methods The preoperative clinical data, surgical treatment, and postoperative conditions of 1 patient with pancreatic cancer who underwent the total pancreatectomy plus splenectomy in the Affiliated Hospital of Qinghai University in January 2018 were retrospectively analyzed. Results Combination of the patient clinical history, physical examination, laboratory and radiologic results, the patient was diagnosed with the pancreatic cancer. Then the patient underwent the Whipple procedure. During the operation, it was found that the texture of the pancreas was hard, and the spleen arteriovenous were considered to be invaded, and the multiple frozen section analysis during the operation showed that the surgical margin was positive. Eventually, the total pancreatectomy plus splenectomy was performed. The postoperative pathological analysis results revealed to the well-moderately differentiated tubular adenocarcinoma. When the condition of patient became stable, the pancreatin and insulin were required for long time. No severe complications occurred. The patient survived well after the surgery and no recurrence was observed for following-up of 3 months. Conclusion With improvement of surgical techniques and enhancement of postoperative management, total pancreatectomy can be used as a treatment for pancreatic cancer and it is still safe and feasible.
Objective To summarize the experiences of middle pancreatectomy. Methods Eleven female and 4 male with a mean age of 49.4 years (23.8-73.1 years) who underwent middle pancreatectomy from January 2001 to October 2005 were collected. Eight patients with neuroendocrine tumor (non-function of 5 cases), 5 with serous cystadenomas and 2 with mucinous cystadenomas were included. The proximal apical end of pancreas was sutured, while distal end of pancreas was anastomosed to a Roux-en-Y jejunal loop. Results Mean operative time was 275 min (179-370 min), mean length of resected pancreas was 45 mm (30-60 mm) and max diameter of tumor was 23 mm (15-40 mm). Complication after operation was pancreatic fistula 〔4 cases (26.7%)〕, in which 3 cases (20.0%) had intraabdominal blood. The mean time of follow-up was 23 months (3 months-5 years). one patient was died of multiple organs failure for pulmonary infections in month 3 after operation, and the others were alive without novo-diabetes. Conclusion Middle pancreatectomy is an effective operation for benign and borderline tumors of neck and body of pancreas without a significant increase of postoperative morbidity.
ObjectiveTo investigate the feasibility and safety of spleen-preserving distal pancreatectomy (SpDP), and to discuss the indications and techniques of SpDP. MethodsThe clinical data of seven patients underwent SpDP between January 2004 and December 2007 in Xinhua Hospital were analyzed retrospectively. ResultsOut of the seven cases, one case received the SpDP combined with partial splenic vessel resection, while the other cases received the SpDP with splenic vessel preservation. The operation time was (2.93±0.38) h and the intraoperative blood loss was (392.86±109.65) ml. Only one case suffered from pancreatic fistula, who finally recovered after medicine therapy and percutaneous drainage. There was no other complication or operative mortality. The postoperative platelet count was (273±43.76)×109/L and the postoperative hospital stay was (17.86±8.07) d. For six cases of patients, no recurrence and metastasis was found after the followup (49.2±14.4) months （30-72 months）. ConclusionSpDP is a safe and feasible procedure, which is worthy for selected cases such as benign neoplasm of the body and tail of the pancreas.
Four techniques in Whipple operation improved by the anthor in this article are as follow: ①the jejunum was pulled up to the area above transverse colon through the duodenal canal behide intestinal mesenteric radix. ②As Hofmeister’s method, the duodenojejunostomy or gastrojejunostomy was made through mesentery of transverse colon. ③The internal drainage tube inserted into the pancreatic duct was extended to about 25 to 30 cm. ④A silicon tube for feeding about 3 mm diameter was placed into distal jejudum through anterior wall of gastric antrum, pylorus and duodenojejunal anastomosis. The techniques and their advantages are elaborated in this paper.
ObjectiveTo explore risk factors for pancreatic fistula and severe pancreatic fistula (grade B and C) after distal pancreatectomy. MethodsOne hundred and fifty patients underwent distal pancreatectomy were collected and analyzed from January 2012 to December 2014 in this retrospective study,among which 61 cases were male,89 cases were female,age from 18 to 78 years old.The risk factors for pancreatic fistula and severe pancreatic fistula after distal pancreatectomy were analyzed by univariate and multivariate logistic regression analysis. ResultsIn these patients,136 cases were underwent laparotomy,8 cases were underwent total laparoscopic surgery,6 cases were underwent hand assisted laparoscopic surgery;39 cases were preserved spleen,111 cases were combined splenectomy.Technique for closure of the pancreas remnant,15 cases were used cut stapler (Echelon 60,EC60),77 cases were used cut stapler (Echelon 60,EC60) combined with manual suture,52 cases were underwent manual cut and suture,and 6 cases were underwent pancreatic stump jejunum anastomosis.The total incidence of complications was 36.0%(54/150),the postoperative hospitalization time was (9.1±6.2) d,the reoperation rate was 2.7%(4/150),the perioperative mortality was 0,the incidence of postoperative pancreatic fistula was 34.7%(grade B and C was 10.0%).In these patients with postoperative pancreatic fistula,the postoperative hospitalization time was (12.6±9.3) d,the reoperation rate was 7.7%(4/52).The results of the univariate and multivariate logistic regression analysis showed that the hypoproteinemia (OR=4.919,P<0.05) was the risk factor for pancreatic fistula after distal pancreatectomy,the malignancy (OR=4.125,P<0.05) was the risk factor for severe pancreatic fistula after distal pancreatectomy. ConclusionsIncidence of pancreatic fistula after distal pancreatectomy is related to hypoproteinemia before operation,it is needed to improve the nutritional status by nutrition treatment for reducing postoperative pancreatic fistula.If patient with malignancy has postoperative pancreatic fistula,it is likely to be severe pancreatic fistula.
Objective To analyze the risk factors of postoperative pancreatic fistula (POPF) after distal pancreatectomy (DP) and to explore the effective index of predicting POPF after DP. Methods The clinical data of 120 patients with pancreatic disease who were treated with DP in the Department of Tumor Surgery of Xuzhou Medical University from January 2010 to November 2017 were analyzed retrospectively. The influencing factors of POPF after DP were analyzed by non-conditional logistic regression. Results Of the 120 patients, 15 patients (12.5%) had clinically significant POPF, including 13 cases of grade B pancreatic fistula and 2 cases of grade C pancreatic fistula. The results of non-conditional logistic regression showed that, the soft pancreas and preoperative pancreatic CT value of the pancreas less than 40 Hu were the independent risk factors of POPF after DP (P<0.05). Conclusions Pancreatic texture and preoperative CT value are important factors influencing the occurrence of POPF after DP. Evaluating the preoperative CT value and intraoperative pancreatic texture can effectively predict the risk of POPF after DP.
The detection rate of benign and borderline/low-grade malignant tumors of pancreas has increased year by year. Most of the patients are middle-aged and young people, who have thirst for high quality of life in long-term. Pancreatic-duct-preserving partial pancreatectomy can meet the needs of reducing surgical trauma, preserving normal pancreatic function and improving patients’ quality of life. However, pancreatic-duct-preserving partial pancreatectomy often needs to face the problem of pancreatic duct defect. Repair of pancreatic duct needs to be applied ? according to different types of pancreatic duct defect. At the same time, the prevention and treatment of pancreatic fistula also require more patience, courage and creativity of pancreatic surgeons. Pancreatic-duct-preserving partial pancreatectomy can solve the current clinical problems. It is safe and feasible with carefully evaluate indications, characters of patients and the personal ability of surgeons.
ObjectiveTo investigate the role of local pancreatectomy for benign and low-grade malignant pancreatic tumors.MethodThe clinical data of 45 patients with benign and low-grade malignant pancreatic tumors who underwent local pancreatectomy from January 2014 to June 2019 in Union Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology were analyzed.ResultsForty-five patients underwent the local enucleation or resection with negative margin. The pathological results showed that there were 17 cases of solid pseudopapilloma, 5 cases of mucinous cystadenoma, 4 cases of serous cystadenoma, 10 cases of islet cell tumor, 5 cases of nonfunctional neuroendocrine tumor, 4 cases of congenital cyst. There were 6 cases of head of pancreas, 26 cases of body of pancreas, 8 cases of tail of pancreas, 5 cases of uncinate process. The tumor was 1.2 to 9.0 cm in diameter with an average of 3.2 cm. Among them, the diameter was more than 5.0 cm in 9 cases. The incidence of pancreatic fistula after operation was 57.8%, 65.4% was grade A fistula, 34.6% was grade B fistula, and no grade C fistula occurred. The incidence of abdominal infection was 13.3%, incidence of abdominal hemorrhage was 6.7%. There was no secondary diabetes mellitus and pancreatic endo- and exocrine dysfunction, and no death case.ConclusionsPancreatic enucleation for benign and low-grade malignant pancreatic tumors after strict preoperative evaluation can effectively preserve the pancreatic endocrine function of patients. Although the incidence of pancreatic fistula is high, it is mostly biochemical fistula, and the incidence of serious complications is low.
ObjectiveTo summarize recent research advancement on radically surgical therapy of carcinoma of the body and tail of pancreas． MethodsRelevant literatures about radically surgical therapy of carcinoma of the body and tail of pancreas were collected and reviewed． ResultsRecent experimental researches indicated that distal pancreatectomy was the common used surgical way to treat carcinoma of the body and tail of pancreas. Besides， spleenpreserving distal pancreatectomy, distal pancreatectomy with en bloc celiac axis resection, and laparoscopic distal pancreatectomy were also the choices to the treatment of carcinoma of the body and tail of pancreas. ConclusionThe surgical way to treat carcinoma of the body and tail of pancreas has advanced for these years, but furthermore development requires more great efforts.
ObjectiveTo explore effect of preoperative prognostic nutritional index (PNI) on clinically related postoperative pancreatic fistula (CR-POPF) after distal pancreatectomy (DP) and analyze its influencing factors in order to provide a basis for clinical prediction of CR-POPF. MethodsThe clinicopathologic data of patients who successfully completed DP in the Affiliated Hospital of Xuzhou Medical University and met the inclusion and exclusion criteria of this study from January 1, 2017 to January 31, 2021 were collected retrospectively. The preoperative PNI value was calculated and the optimal cut-off value was obtained according to the receiver operative characteristic (ROC) curve. The patients were divided into low and high PNI based on the optimal cut-off value. The clinicopathologic characteristics were compared between the patients with low and high PNI and CR-POPF or not. At the same time, multivariate logistic regression was used to analyze the influencing factors of CR-POPF. ResultsA total of 143 patients who met the inclusion and exclusion criteria were included in this study. The CR-POPF occurred in 33 cases (23.08%) after DP, and the average preoperative PNI was 52.26 (39.20–65.10), the optimal cut-off value of PNI was 50.55, with 49 cases in the low PNI group and 94 cases in the high PNI group. In patient with low PNI, the proportions of patients aged ≥65 years and with CR-POPF were higher than those with high PNI (P<0.05). In the patients with CR-POPF, the proportions of patients with soft pancreatic texture and with low preoperative PIN were higher than those without CR-POPF (P<0.05). Further, the multivariate logistic regression showed that the the preoperative low PNI (OR=5.417, P<0.001) and soft pancreatic texture (OR=4.126, P=0.002) increased the risk of CR-POPF. ConclusionLow preoperative PNI and soft pancreatic texture increase risk of CR-POPF after DP, and it is necessary to preoperatively evaluate PNI status of patients.
