Objective To summarize the risk factors, diagnosis, and treatment experience of intra-abdominal bleeding following surgeries for severe acute pancreatitis. Methods A retrospective review was conducted of 347 patients underwent necrosectomy for severe acute pancreatitis between January 2011 and December 2015 at West China Hospital of Sichuan University. Results Of the 347 patients, thirty-eight patients had intra-abdominal bleeding after surgeries, including 5 patients who had twice bleeding. The bleeding positions including splenic vein (n=7), splenic artery (n=2), pancreatic and peripancreatic vessels (n=8), colonic mesangial vessels (n=6), other vessels (n=12), and extensive osmotic bleeding in abdominal cavity (n=7). Hemostatic modes: suture (n=20), compression hemostasis (n=18), transcatheteranerial embolism (n=2), suture and compression hemostasis (n=4), and conservative treatment (n=1). There were 19 dead patients of 38 bleeding patients. There were statistically significant differences between the hemorrhage group and the non-hemorrhage group on gender, acute physiology and chronic health evaluation (APACHEⅡ) scores and modified Marshall scores at admission, interval onset to surgery, surgical approaches, and morbidity (P<0.05). Compared with the non-hemorrhage group, there were more males, higher APACHE Ⅱ scores and modified Marshall scores, longer interval onset to surgery, and higher mortality in the hemorrhage group. Multivariable logistic regression analysis showed that male patients had higher risk of intra-abdominal bleeding (OR=3.980, P=0.004), as the grow of APACHEⅡ scores, the risk of intra-abdominal bleeding increased (OR=1.487, P<0.001). Conclusions We should pay more attention on the male SAP patients as well as patients with multiple organ dysfunction.
Objective To compare anastomotic fistula of modified triple-layer duct-to-mucosa pancreaticojejunostomy and end-to-end invagination pancreaticojejunostomy following pancreaticoduodenectomy. Methods The clinical data of 147 patients underwent pancreaticoduodenectomy from January 2015 to June 2017 in the West China Hospital of Sichuan University were retrospectively analyzed. The modified triple-layer duct-to-mucosa pancreaticojejunostomy were used in 101 cases (MTL group) and end-to-end invagination pancreaticojejunostomy were used in 46 cases (IPJ group). The differences of intraoperative and postoperative statuses were compared between the two groups. Results The baseline data of these two groups had no significant differences (P>0.05). Except for the average time of the pancreaticoenterostomy of the MTL group was significantly longer than that of the IPJ group (P<0.05), the intraoperative blood loss, the first postoperative exhaust time, postoperative hospitalization time, reoperation rate, death rate, and rates of complications such as the pancreatic fistula, biliary fistula, anastomotic bleeding, gastric emptying disorder, and intraperitoneal infection had no significant differences between these two groups (P>0.05). Conclusions Both modified triple-layer duct-to-mucosa pancreaticojejunostomy and end-to-end invagination pancreaticojejunostomy following pancreaticoduodenectomy are safe and effective. An individualized selection should be adopted according to specific situation of patient.
Objective To explore the application of artificial intelligence in the risk assessment and diagnosis of pancreatic cancer, and to point out its limitations and future suggestions, so as to promote the further application of artificial intelligence in the future. Method The related literatures on the application of artificial intelligence in the risk assessment and diagnosis of pancreatic cancer at home and abroad in recent years were reviewed. Results The usage of artificial intelligence models to assess high-risk patients was beneficial to the diagnosis of pancreatic cancer, although more data were needed to support its role in pancreatic cancer screening. In terms of early diagnosis, artificial intelligence technology could rapidly locate high-risk groups through medical imaging, pathological examination, biomarkers, and so on, and then detected pancreatic cancer at an early stage. Conclusion Despite some limitations, artificial intelligence will play an important role in the early diagnosis and risk prediction of pancreatic cancer in the future due to its powerful computational power.
Objectives To identify the effect of procalcitonin (PCT) on the choice of operating time for severe acute pancreatitis and assessment of postoperative complications by monitoring the level of serum PCT and recording the incidence of postoperative complications. MethodsNinety-three patients who underwent debridement and drainage of infected necrosis from Sep. 2009 to Dec. 2011 were included. Serum PCT was tested on the day of admission (0 day), one week after admission, one day before surgery, one day after surgery, and one week after surgery. According to the level of serum PCT, all the 93 patients were divided into 3 groups:low level group (PCT < 2 ng/mL), middle level group (PCT 2-10 ng/mL), and high level group (PCT > 0 ng/mL). Postoperative complications were also recorded. ResultsThe incidence of postoperative complications was 19.4% (18/93). There were postoperative bleeding in 13 patients, intestinal fistula in 14 patients, pancreatic fistula in 18 patients, pulmonary infection in 4 patients, residual abscess in 10 patients; re-operation in 15 patients, and death in 8 patients (the death rate was 8.6%). Besides the pulmonary infection, and grade A and C of pancreatic fistula, the incidence of various complications in middle level group and high level group were lower than low level group (P < 0.05). Patients with complications had significantly higher PCT value in one week after admission than onset (P < 0.05). PCT value was higher in the patients with intestinal fistula and residual abscess on one day after operation than on one day before operation (P < 0.05). Patients who died or with re-operation had significantly higher PCT value in one week after operation than on one day after operation (P < 0.05). In the dead patients, the serum PCT sustained at a high level after operation. ConclusionsThe level of serum PCT is correlated with the incidence of postoperative complications. Dynamic monitoring the level of serum PCT can guide the choice of operative time and assessment of postoperative complications including intestinal fistula, pulmonary infection, and death, which can greatly improve the prognosis of SAP.
ObjectiveTo investigate the current status and research progress of radioactive 125I seed implantation in the treatment of unresectable pancreatic cancer.MethodsReviewed the relevant literatures to summarize and analyze the mechanism of action, indications and contraindications, implantation methods, clinical efficacy, complications, and treatment measures of radioactive 125I seed implantation in the treatment of pancreatic cancer.ResultsThe mechanism of radioactive 125I seed implantation in the treatment of pancreatic cancer had been deeply studied in terms of gene expression and molecular signal level. The procedure was applicable to a wide range of patients; the implantation methods were abundant, CT and ultrasound guidance had their advantages; it could effectively inhibit tumor growth and improve overall survival rate. It was dramatically for pain relief, as well as low overall complication rate, and the complications could be alleviated by symptomatic treatment.ConclusionRadioactive 125I seed implantation in the treatment of unresectable pancreatic cancer has been widely promoted due to its simple operation and small trauma, and it is effective in controlling tumor growth, prolonging survival, and relieving pain.
Objective To explore treatment strategy of pancreatic pseudocyst induced left-sided portal hypertension (LSPH) complicated with hypersplenism. Methods The clinical data of 49 cases of pancreatic pseudocyst induced LSPH complicated with hypersplenism from January 2010 to June 2015 in this hospital were retrospectively analyzed. Among them, 36 patients who were not complicated with upper gastrointestinal bleeding were designed to splenectomy group and non-splenectomy group based on splenectomy or not. The epidemiological and clinical features, intraoperative and postoperative results of these two groups were compared. Results There were 38 males and 11 females with age ranging from 22 to 67 years old. As for 13 patients suffering LSPH complicated with hypersplenism caused by pancreatic pseudocyst with upper gastrointestinal bleeding, one patient didn’t accept splenectomy, then the upper gastrointestinal bleeding recurred and the hypersplenism was not alleviated after operation; Whereas, the hypersplenisms were relieved in the others patients after operation. In the 36 patients without upper gastrointestinal bleeding who were complicated with hypersplenism, 23 patients were performed splenectomy (splenectomy group) and 13 patients were not (non-splenectomy group). In the splenectomy group, the blood loss, operation time, and intraoperative blood transfusion were significantly more than those of the non-splenectomy group (P<0.05). The hospital stay and the discharged laboratory examinations had no significant differences between the splenectomy group and the non-splenectomy group (P>0.05) except for the platelet count. Furthermore, the incidence of the postoperative upper gastrointestinal bleeding was lower (P<0.05) and the relief rate of hypersplenism was higher (P<0.05) in the splenectomy group as compared with the non-splenectomy group. Conclusions For pancreatic pseudocyst induced LSPH with hypersplenism, we should be vigilant and early intervent. Usually, primary focus can be treated only. However, splenectomy can effectively relieve hypersplenism and prevent recurrent bleeding for patients with upper gastrointestinal bleeding or patients with close adhesion of pancreas tail and spleen inflammatory lesions and constricting splenic hilus.
