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 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.
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.
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 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 the safety and feasibility of spleen-preserving distal pancreatectomy for children with distal pancreatic injures.MethodsClinical data of 10 patients with severe distal pancreatic injures in The Second Affiliated Hospital of Guilin Medical University from January 2012 to July 2017 were retrospectively analyzed. The intraoperative and postoperative situation including operation time, intraoperative blood loss, postoperative blood platelet count, and perioperative complications were observed.ResultsAll the 10 patients underwent spleen-preserving distal pancreatectomy successfully. The median operation time was 3 h (2–6 h), the median intraoperative blood loss was100 mL (50–300 mL), the postoperative blood platelet count ranged from 75×109/L to 260×109/L with the median postoperative blood platelet count was 175×109/L. Two patients suffered from pancreatic leakage, one patient suffered from subphrenic infection, and one patient suffered from pulmonary infection. All patients suffered from complication recovered after symptomatic treatments. All patients were followed up in the outpatient department, the follow-up time was 4–60 months with a median of 30 months. Reexamination of abdominal ultrasound and blood routine (every 3 months after surgery) showed that, no abnormalities in blood supply, morphology, and structure of spleen, and platelet counts fluctuated within the normal range. During the follow-up period, none of the children suffered from severe infection due to hyposplenic function.ConclusionSpleen-preserving distal pancreatectomy is a safe and effective method for children with distal pancreatic injures.
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.
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.
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.
Objective To explore the risk factors of postoperative anxiety in patients with pancreatic cancer undergoing total pancreatectomy. Methods A total of 31 patients who underwent total pancreatectomy for pancreatic cancer between July 2011 and December 2016 were collected and analyzed in this retrospective study. The patients’ postoperative Self-Rating Anxiety Scale scores were collected, and the exposure factors were analyzed to identify the risk factors of postoperative anxiety through univariate analysis and multiple logistic regression analysis by SPSS 21.0 statistical software. Results In the 31 patients, there were 17 males and 14 females, with an average age of (66.16±9.09) years, an average body mass index of (21.11±3.10) kg/m2, and an average postoperative hospital stay of (14.58±7.47) days. There were 23 patients (74.2%) with postoperative anxiety, and 30 patients (96.8%) with hyperglycosemia required insulin therapy. The total perioperative mortality was 3.2%. In the univariate analysis, age (P=0.012), smoking history (P=0.043), preoperative diabetes mellitus (P=0.012), postoperative bile leakage (P=0.043), and postoperative abdominal infection (P=0.026) were related factors of the postoperative anxiety. In the multiple logistic regression analysis, patients without preoperative diabetes was an independent risk factor of postoperative anxiety (P=0.013). Conclusions For patients undergoing total pancreatectomy, it is needed to pay attention to the patients’ postoperative psychological conditions and assess the postoperative anxiety, especially for those without preoperative diabetes. To improve the life quality and long-term survival of these patients, health education and psychological intervention are needed.
