ABSTRACT

Objective:To evaluate the early predictive value of serum procalcitonin (PCT) , C-reactive protein (CRP) , and white blood cell count (WBC) levels for pancreatic fistula after pancreaticoduodenectomy (PD) .Methods:Data of 93 patients undergoing PD in Department of Pancreatic Surgery at the First Affiliated Hospital of Xinjiang Medical University from Jan. 2017 to Nov. 2019 were retrospectively analyzed. The general information of patients before surgery and postoperative pancreatic fistula were recorded. The levels of serum PCT, CRP, and WBC before surgery and 1st, 3rd, and 5th days after operation were recorded. Patients were divided into pancreatic fistula group (63 cases) and non-pancreatic fistula group (30 cases) . The preoperative data were compared between the two groups. Box plot and the receiver operating characteristic curve (ROC) were drawn. The area under the ROC curve (AUC) was calculated. The sensitivity and specificity of PCT, CRP, and WBC levels in predicting pancreatic fistula alone and jointly were calculated.Results:There were no statistically significant differences in the age, gender, presence or absence of diabetes, total bilirubin, preoperative albumin, surgical time, or intraoperative bleeding in the general information of the pancreatic fistula group and the non-pancreatic fistula group. The difference in index (BMI) was statistically significant. The value of PCT, CRP, and WBC before operation and the value of PCT on the first day after operation were not statistically significant between the two groups ( P=0.424, 0.819, 0.484, and 0.072, respectively) . The PCT values on the 3rd and 5th days after surgery, the values of CRP and WBC on the 1st, 3rd, and 5th days after surgery were all statistically significant (all P values were<0.05) . The area under the ROC curve was jointly predicted by the three at the 3rd and 5th days after operation (AUC=0.792, 0.812) , and the sensitivity (62.9%, 71.4%) and specificity (83.3%, 80%) were better than the three alone. Conclusion:PCT, CRP, and WBC values on the 1st, 3rd, and 5th days after surgery alone have certain limitations in predicting pancreatic fistula, and the combined prediction of the three is more valuable.

ABSTRACT

Objective The risk of current pancreaticojejunostomy is carefully considered from the perspective of the morphology of remnant pancreas,and we aimed to discuss the clinical outcomes of selecting different pancreaticojejunostomy techniques based on pancreatic morphology.Methods This was a prospective cohort study.The histopathology of remnant pancreatic tissues was categorized into four types based on preoperative radiological images and intraoperative palpation:Type Ⅰ:pancreas with hard texture in palpation,pancreatic atrophy,dilated pancreatic duct larger than 5 mm and remnant pancreatic surface <3 cm;Type Ⅱ:pancreas with hard texture in palpation,pancreatic atrophy and mild dilatation of pancreatic duct with the diameter of 3-5 mm and remnant pancreatic surface <3 cm;Type Ⅲ:pancreas with slightly hard texture,no atrophy,and normal or slightly dilated pancreatic duct with the diameter of 3-5 mm and remnant pancreatic surface ≥3 cm;Type Ⅳ:pancreas with soft texture,normal morphology and pancreatic duct.Results From January 2008 to August 2017,116 consecutive patients underwent pancreaticoduodenectomy in our center.Among them,10 patients with type Ⅰ underwent classic pancreatic ductal mucosa to mucosa anastomosis.19 patients with type Ⅱ underwent classic end to end invaginated pancreaticojejunostomy.45 patients with type Ⅲ underwent classic end to end invaginated pancreaticojejunostomy with overlapping U sutures;42 patients with type Ⅵ underwent total invaginated pancreaticojejunostomy.The post-operative pancreatic fistula occurred in 6 patients (5.2%) with one patient died.Postoperative bleeding occurred in 10 patients (8.6%),and gastroparesis occurred in 22 patients (19.0%).Overall complication rate was 33.6%.Conclusions Classification of pancreatic morphology based on preoperative radiological images and intraoperative palpation and the selection of corresponding pancreaticojejunostomy technique is theoretically rational and has the advantage of potentially reducing the risk of remnant pancreatic tissue.

ABSTRACT

BACKGROUND:Central pancreatectomy is a surgical treatment for tumors at the neck or the middle part of the pancreas, which can reserve more normal pancreas, not cut adjacent organs, and reduce the incidence of postoperative internal and external pancreatic secretion deficiency with respect to the expanded proximal and distal pancreatectomy. OBJECTIVE: To systematicaly evaluate the clinical efficacy of the central pancreatectomy and distal pancreatectomy. METHODS: A computer-based search of Chinese and English databases was performed, and then 15 controled clinical trials were included and systematicaly evaluated using RevMa5.2 software. RESULTS AND CONCLUSION: Totaly 1 079 cases were included in this study, which consisted of 436 central pancreatectomy cases and 643 distal pancreatectomy cases. Meta-analysis showed that compared with the distal pancreatectomy group, the incidences of postoperative pancreatic fistula and complications were significantly higher, the risk of postoperative endocrine and exocrine insufficiency were significantly lower, while the surgical time (SMD: 59.23, 95%CI: 22.41-96.05, P < 0.01) and hospital stays (SMD: 7.01, 95%CI: 1.94-12.09,P< 0.01) were longer in the central pancreatectomy group. These findings indicate that although the central pancreatectomy has a high postoperative complication incidence, it can be accepted clinicaly, which may be a reasonable operation method to preserve pancreatic exocrine and endocrine function.

ABSTRACT

Objective To study the results of splenectomy for patients with idiopathic thrombocytopenic purpura(ITP), which refractory to medical therapy or with repeat recurrence of symptoms. Methods 58 ITP (patients) who failed to respond to conservative management were treated with splenectomy and the clinical (outcome) was observed. Postoperatively, 52 cases were followed up for 6 months to 12 years, and in 48 of these cases the followup was more than 1 year. Results Platelet count recovered to normal(≥100?10~9/L ) two weeks after operation in 47 cases(81.03%). The total effective rate was 79.31% when (followed-up) for 2 months, 78.85% when followed-up for 6 months and 11 cases had recurrence. (Conclusions) Splenectomy is a safe and effective therapy for patients with ITP who failed to respond to (conservative) management or have relapse of ITP. Patients who showed temporary response to preoperative (steroid) therapy and those who had an early or a high amplitude of increase of platelet count after operation have better prognosis.
