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.
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 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 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 summarize the key technical points, applicability, feasibility, and safety of laparoscopic spleen-preserving distal pancreatectomy (LSPDP).MethodA retrospective analysis was performed for the clinical data of 22 patients who were admitted to the Affiliated Hospital of North Sichuan Medical College from September 2016 to November 2019, all patients planned to receive LSPDP.ResultsTwenty of the 22 patients successfully completed LSPDP, and 2 patients converted to laparotomy. One patient was transferred to laparotomy to suture the damaged splenic artery. The spleen was observed to have no ischemia and the spleen preservation operation was continued. One patient was converted to laparotomy due to the difficulty of dissecting the tail of the pancreas which caused by severe abdominal adhesion. The operation time of LSPDP patients was (191±86) minutes (170–480 min), intraoperative blood loss was (365±50) mL (200–1 000 mL), and postoperative hospital stay was (9.9±2.6) days (7–16 d). Six patients of pancreatic fistula occurred after operation, including 3 cases of biochemical fistula, which were cured and discharged after symptomatic treatment, 3 cases of grade B pancreatic fistula, who all improved after anti-inflammatory, acid suppression, enzyme suppression, and double catheter drainage. Twenty patients were interviewed after the operation, and the follow-up time was 3–24 months (median of 15 months). During the follow-up period, no patient had recurrence or metastasis.ConclusionsUnder the conditions of strict screening of suitable cases, adequate preoperative imaging evaluation, intraoperative fine manipulation, and the application of appropriate operating instruments and cutting closure devices, LSPDP is safe and feasible to treat benign tumors of the pancreatic body and tail and some borderline tumors. During the operation, attention should be paid to the reasonable treatment and protection of splenic arteries and veins.
ObjectiveTo explore the security and advantages of laparoscopic spleen-preserving distal pancreatectomy (LSPDP) for occupancy lesions in pancreatic body and tail. MethodsA total of 97 patients with occupancy lesions in pancreatic body and tail who underwent laparoscopic distal pancreatectomy in our hospital from June 2010 to August 2014 were collected retrospectively, and were divided into LSPDP group (n=60) and laparoscopic distal pancreatectomy with splenectomy (LDPS) group (n=37) according to the surgery, clinical effect was compared between the 2 groups. ResultsThe operations got well in all patients, no one died during perioperative period. The operation time was shorter in LSPDP group than that of LDPS group[(190.83±66.39) min vs. (224.46±83.23) min, P=0.030], but there was no significant difference between LSPDP group and LDPS group in the blood loss[45.35 mL vs. 54.92 mL], hospital stay[(8.38±4.06) d vs. (9.76±4.54) d], incidence of total postoperative complication[23.33% (14/60) vs. 13.51% (5/37)], and degree of postoperative complication (P>0.050). There were 86 patients were followed up for 3-54 months, with the median time of 18 months. For patients with tumor, no one suffered from recurrence, metastasis, and death during the follow-up period, and other patients with benign diseases had an excellent prognosis. ConclusionFor occupancy lesions in pancreatic body and tail, LSPDP is feasible and safe.
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.
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.
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 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.
