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 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 evaluate feasibility and clinical application value of laparoscopic spleen-preserving distal pancreatectomy (LSPDP). Method The clinical data of 17 patients underwent LSPDP from January 2015 to June 2017 in this hospital were retrospectively analyzed. Results The LSPDP was successfully completed in the 17 cases, with Kimura procedure and Warshaw procedure were performed in the 12 cases and 5 cases, respectively. The operative time was (218±60) min, the intraoperative blood loss was (136±114) mL, the time to get out of bed after surgery was (1.4±0.6) d, the postoperative fasting time was (2.0±0.8) d, and the postoperative hospital stay was (13.4±5.7) d. The rate of the postoperative pancreatic fistula was 17.6% (3/17). The spleen infarction occurred in the 2 cases following the Warshaw procedure. The pathologic examination showed that there were 2 patients with the serous cystadenoma, 7 patients with the mucinous cystadenoma, 3 patients with the solid pseudo-papillary tumor, 3 patients with the intraductal papillary mucinous cystadenoma neoplasm, and 2 patients with the insulinoma. All the patients were followed-up for 5 to 26 months (average 13 months), and the perigastric varice occurred in 1 patient, no recurrence or spleen infarction occurred during the following-up. Conclusion LSPDP is a safe, feasible and effective method with less injury and rapid recovery.
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.
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 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.
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 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.
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.
