Frequency of major complications after EUS-guided FNA of solid pancreatic masses: a prospective evaluation.
ABSTRACT EUS-guided FNA is effective for establishing tissue diagnosis in suspected pancreatic cancer. However, data on the frequency of major complications following EUS-FNA are limited.
To evaluate the frequency of major complications after EUS-FNA of solid pancreatic masses.
Prospective cohort study.
Tertiary University based referral center for pancreatico-biliary disorder.
Consecutive patients who underwent EUS-FNA of a solid pancreatic over a 42-month period. All immediate complications were recorded by the endosonographer. Late complications were assessed at 72 hours and at 30-days after the procedure.
Major complications were defined as acute pancreatitis, bleeding, infection, perforation, use of reversal medication, hospitalization or death.
A total of 355 consecutive patients with a solid pancreatic mass underwent EUS FNA. Major complications were encountered in 9 patients (2.54%, 95% CI 1.17-4.76). Acute pancreatitis occurred in 3 of 355 (0.85 %, 95% CI 0.17-2.45); 2 patients were hospitalized, and 1 patient recovered with outpatient analgesics. Three patients were admitted for severe pain after the procedure; all were treated with analgesics and subsequently discharged with no sequela. Two patients (0.56%, 95% CI 0.07-2.02) developed fever and were admitted for intravenous antibiotics; 1 patient recovered with intravenous antibiotics and the other required surgical debridement for necrosis. One patient required the use of reversal medication. Overall, 1.97% (95% CI 0.80-4.02) of the patients were hospitalized for complications (range 1-16 days). None of the patients experienced clinically significant hemorrhage, perforation, or death. No clear predisposing risk factors were identified.
Lack of surgical gold standard and referral to a tertiary center.
EUS-FNA of solid pancreatic masses infrequently leads to major complications. Our results can be used by endosonographers to counsel patients before EUS-FNA of solid pancreatic masses.

ABSTRACT: The aim of this study was to determine the frequency and the severity of pancreatitis after EUS-guided FNA of solid pancreatic masses. A survey of centers that offer training in EUS in the United States was conducted. A list of centers in which training in EUS is offered was obtained from the Web site of the American Society for Gastrointestinal Endoscopy. Designated program directors were contacted via e-mail. The information requested included the number of EUS-guided FNA procedures performed for solid pancreatic masses, the number of cases of post-procedure pancreatitis, and the method for tracking complications. For each episode of pancreatitis, technical details were obtained about the procedure, including the location of the mass, the type of fine needle used, the number of needle passes, and the nature of the lesion. Nineteen of the 27 programs contacted returned the questionnaire (70%). In total, 4909 EUS-guided FNAs of solid pancreatic masses were performed in these 19 centers over a mean of 4 years (range 11 months to 9 years). Pancreatitis occurred after 14 (0.29%): 95% CI[0.16, 0.48] procedures. At two centers in which data on complications were prospectively collected, the frequency of acute pancreatitis was 0.64%, suggesting that the frequency of pancreatitis in the retrospective cohort (0.26%) was under-reported (p=0.22). The odds that cases of pancreatitis would be reported were 2.45 greater for the prospective compared with the retrospective cohort (95% CI[0.55, 10.98]). The median duration of hospitalization for treatment of pancreatitis was 3 days (range 1-21 days). The pancreatitis was classified as mild in 10 cases, moderate in 3, and severe in one; one death (proximate cause, pulmonary embolism) occurred after the development of pancreatitis in a patient with multiple comorbid conditions. EUS-guided FNA of solid pancreatic masses is infrequently associated with acute pancreatitis. The procedure appears to be safe when performed by experienced endosonographers. The frequency of post EUS-guided FNA pancreatitis may be underestimated by retrospective analysis.Gastrointestinal Endoscopy 10/2004; 60(3):385-9. · 5.21 Impact Factor

ABSTRACT: Diagnosis of pancreatic tumors can be problematic. This study aimed to determine the performance of endoscopic ultrasound-guided fine needle aspiration biopsy (EUS FNA) in pancreatic malignancy when prior biopsies performed by CT guidance or ERCP were negative. A total of 185 patients with known or suspected pancreatic masses were prospectively evaluated with EUS FNA. Before EUS FNA, all patients were evaluated with abdominal CT (61 with CT-guided biopsy) and 91 with ERCP (41 had brushings or biopsy). EUS had greater sensitivity than CT in detecting a mass (99% vs 57%, p < 0.0001). In 58 patients with negative CT-guided biopsies, EUS FNA had 90% sensitivity for malignancy, 50% specificity for benign disease and 84% accuracy. Similarly, in 36 patients with negative ERCP tissue sampling, results for EUS FNA were 94%, 67% and 92%, respectively. Complications were mild and infrequent (0.5%). EUS FNA of pancreatic masses safely and accurately diagnoses pancreatic malignancy when prior biopsy techniques have been unsuccessful.The American Journal of Gastroenterology 06/2002; 97(6):1386-91. · 7.55 Impact Factor
