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.
Objective To study the clinical significance of central pancreatectomy in treatment of benign tumor of neck and body of pancreas. Methods The clinical data of 29 patients with benign tumor of pancreas were reviewed retrospectively in our hospital during the past 5 years. Results There was no perioperative death. Mean of operative time was （165±45） min （125-270min）， mean of blood loss was （173±88） mL （50-450mL）. The pathological diagnosis of all the patients were benign. Pancreatic fistula occurred in 10 patients. One patient with bleeding after operation was treated with another two operations. Twenty-one patients were followed-up with the time ranged from 3 months to 4 years （average 16 months）. There were no complications related to diabetes. Conclusion Central pancreatectomy is reasonable for patients with benign tumor of pancreas， it could well preserve the endocrine and exocrine function of pancreas， and improve the quality of life of patients.
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 investigate the factors that affect the occurrence of postoperative pancreatic fistula (POPF) after distal pancreatectomy (DP).MethodsThe clinical data of 114 patients underwent DP who were performed in the First Affiliated Hospital of Xinjiang Medical University from Jan. 2014 to Jun. 2019, were retrospectively analyzed.ResultsIn this group of 114 patients, 43 cases (37.7%) of POPF occurred after DP, including 19 cases of grade A (biochemical fistula), 21 cases of grade B, and 3 cases of grade C. The univariate analysis results showed that: BMI value, drinking history, preoperative plasma albumin level, postoperative plasma albumin level, postoperative neutrophil/lymphocyte ratio (NLR), preoperative and postoperative prognostic nutrition index (PNI) levels were significant different between the POPF group and non-POPF group (P<0.05). Multivariate analysis results showed that: preoperative plasma albumin>35 g/L [OR=0.115, 95%CI was (0.038, 0.348)], postoperative plasma albumin>35 g/L [OR=0.126, 95%CI was (0.031, 0.516)], and postoperative NLR value≤6.65 [OR=0.149, 95%CI was (0.048, 0.461)] were the influencing factors of POPF after DP. The area under curve of postoperative NLR was 0.731 [95%CI was (0.639, 0.824)]. ConclusionPreoperative and postoperative plasma albumin>35 g/L, as well as postoperative NLR ≤6.65 are protective factors for POPF after DP, and postoperative NLR can be used as a predictor of POPF.
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.
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.
ObjectiveTo summarize the effect of the multi-disciplinary treatment (MDT) for a patient with giant pancreatic cystic lymphangioma.MethodsThe clinical data of a patient with pancreatic lymphangioma admitted to the Affiliated Hospital of North Sichuan Medical College in March 2020 was retrospectively analyzed, then reviewed the literatures, and summarized the preoperative diagnosis, treatment, and management of perioperative period and long-term period after surgery of this rare disease.ResultsAfter admission, the patient was diagnosed as pancreatic tumor by various imaging and laboratory examinations. The nature was unknown. After discussion by MDT, it was decided to undergo a total pancreatectomy (TP). After the operation, drugs and diet were given to regulate blood glucose. The patient’s tumor disappeared after the operation, and no tumor recurrence was found in the three months after discharge.ConclusionsPancreatic lymphangioma is rare and lacks a clear diagnosis and treatment plan. The MDT mode can bring a clearer diagnosis and more effective treatment for it.
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.
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 evaluate the short-term effectiveness of robotic distal pancreatectomy (RDP) and laparoscopic distal pancreatectomy (LDP) by meta-analysis.MethodsWe searched for manuscripts about RDP versus LDP form PubMed, The Cochrane Library, EMbase, CKNI, CBM, and WanFang Databases. The parallel quality assessment was selected according to the literature inclusion and exclusion criteria. Relevant data were extracted and meta-analysis was performed by using Revman 5.3 software.ResultsA total of 23 articles were included, and a total of3 487 patients enrolled who underwent pancreatic body resection. Meta-analysis results showed that compared with the LDP group, the RDP group had a longer operation time [MD=15.52, 95%CI was (0.60, 30.45), P=0.04], but the intraoperative blood loss was less [MD=–59.18, 95%CI was (–111.62, –6.73), P=0.03], the intraoperative spleen preservation rate was higher [OR=1.74, 95%CI was (1.02, 2.96), P=0.04], the intraoperative conversion to open rate was lower [ OR=0.45, 95%CI was (0.34, 0.60), P<0.000 01], and postoperative hospital stay was shorter [MD=–0.90, 95%CI was (–1.70, –0.10), P=0.03], while there were no significant differences in intraoperative blood transfusion rate [OR=0.88, 95%CI was (0.60, 1.30), P=0.52], incidence of postoperative overall complication [OR=0.88, 95%CI was (0.68, 1.13), P=0.32] and pancreatic leakage [OR=0.91, 95%CI was (0.72, 1.14), P=0.41], 90-day readmission rate [OR=1.32, 95%CI was (0.95, 1.83), P=0.10], and 90-day reoperation rate [OR=0.73, 95%CI was (0.40, 1.33), P=0.30].ConclusionsRDP has the advantages of less bleeding, low turnover rate, and short postoperative hospital stay. However, due to the quality limitations of the included studies, the above conclusions still need to be verified by more high-quality studies.
