Aim
The aim was to determine the accuracy of C‐reactive protein (CRP), procalcitonin and neutrophils in the early detection (fourth postoperative day) of anastomotic leakage (AL) after colorectal surgery.
Methods
We conducted a multicentre, prospective study that included a consecutive series of patients who underwent colorectal resection with anastomosis without ostomy (September 2015 to December 2017). CRP, procalcitonin and neutrophil values on the fourth postoperative day after colorectal resection along with the postoperative outcome (60‐day AL, morbidity and mortality) were prospectively included in an online, anonymous database.
Results
The analysis ultimately included 2501 cases. The overall morbidity and mortality was 30.1% and 1.6%, respectively, and the AL rate was 8.6%. The area under the receiver operating characteristic curve values (95% CI) for detecting AL were 0.84 (0.81–0.87), 0.75 (0.72–0.79) and 0.70 (0.66–0.74) for CRP, procalcitonin and neutrophils, respectively. The best cut‐off level for CRP was 119 mg/l, resulting in 70% sensitivity, 81% specificity and 97% negative predictive value. After laparoscopic resection, the accuracy for CRP and procalcitonin was increased, compared with open resection. The combination of two or three of these biomarkers did not significantly increase their accuracy.
Conclusion
On the fourth postoperative day, CRP was the most reliable marker for excluding AL. Its high negative predictive value, especially after laparoscopic resection, allows for safe hospital discharge on the fourth postoperative day. The routine use of procalcitonin or neutrophil counts does not seem to increase the diagnostic accuracy.
Background: Pancreatic neuroendocrine tumors (PNET) are a heterogeneous group and constitute 1.3% of all pancreatic tumors. Approximately 10% of these occur in the context of hereditary syndromes, such as VHL disease.Case report: We report a case of a female patient of 37 years diagnosed VHL and intervened on several occasions by cerebral hemangioblastoma and renal carcinomas. During its follow-up she was diagnosed 2 gastrinomas functioning under 2 cm were enucleated. Later developed new PNET and underwent a total duodenopancreatectomy without pyloric preservation.Discussion: The management of PNET in VHL is difficult due to the association of multiple tumors in different organs and the morbidity and mortality associated with the surgery of the pancreas. Management must be individualized for each patient, based on the ability to produce hormones and present symptoms, the size and location, and in the context of other tumors that usually present in these patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
