What is the purpose of this trial?

This trial explores better ways to diagnose pancreatic cysts, which are fluid-filled sacs in the pancreas. Researchers aim to determine if using a tiny tool called micro forceps, along with the standard fine needle aspiration (FNA), provides more accurate results in identifying potentially cancerous cysts. Participants will undergo either the usual FNA procedure alone (EUS-FNA Alone) or FNA combined with micro forceps biopsy (EUS-FNA plus MFB). This trial targets adults with pancreatic cysts larger than 20mm that are suitable for sampling, as determined by a doctor. The goal is to improve diagnostic methods, aiding doctors in choosing the best treatment paths. As an unphased trial, this study offers participants the chance to contribute to pioneering research that could enhance diagnostic accuracy for future patients.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What prior data suggests that this method is safe for diagnosing pancreatic cysts?

Research shows that both EUS-FNA and EUS-FNA with MFB are generally safe for diagnosing pancreatic cysts.

For EUS-FNA alone, studies indicate it is usually well-tolerated. Pancreatitis, an inflammation of the pancreas, occurs rarely and mildly after the procedure. No deaths were reported in the studies, suggesting it is low-risk.

EUS-FNA with MFB, which includes an additional small tissue sample, also appears safe. A study with 101 patients found it was well-tolerated. A review of multiple studies supports this, showing the method is safe and effective for diagnosing these cysts.

Overall, both methods have a strong safety record, with low rates of serious complications. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about exploring EUS-FNA with and without micro-forceps biopsy (MFB) for pancreatic cysts because it could enhance diagnostic precision. Unlike the standard EUS-FNA, which uses just a needle, the addition of micro-forceps allows for the collection of larger and more intact tissue samples, potentially leading to more accurate diagnoses. This could be a game-changer for patients, as a more precise diagnosis can lead to better treatment planning and potentially improved outcomes.

What evidence suggests that this trial's treatments could be effective for pancreatic cysts?

Research has shown that EUS-FNA, a procedure using a thin needle guided by ultrasound, effectively diagnoses pancreatic cysts. It is 91% accurate in identifying solid growths in the pancreas, though its accuracy can vary with cystic lesions. In this trial, one group of participants will receive EUS-FNA alone, while another group will receive EUS-FNA plus MFB. MFB, a technique using tiny forceps to take tissue samples from the cyst wall, seems to improve accuracy. Studies indicate that MFB can provide a better diagnosis by offering insights that fluid tests alone might miss. Together, these methods may help doctors better understand and treat pancreatic cysts. ^{4 6 7 8 9}

Published Research Related to This Trial

In a meta-analysis of 18 randomized controlled trials involving 2718 patients, endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB) showed better diagnostic accuracy and adequacy for solid gastrointestinal lesions compared to fine-needle aspiration (EUS-FNA), requiring fewer needle passes to obtain sufficient tissue.

For solid pancreatic lesions, there was no significant difference in diagnostic accuracy or tissue quality between EUS-FNA and EUS-FNB, indicating that both methods are equally effective for this specific type of lesion.

Endoscopic ultrasound (EUS) guided fine-needle aspiration (FNA) is a safe and accurate method for diagnosing intrathoracic and intraabdominal conditions, but it carries a low risk of adverse events such as perforation, infections, and bleeding.

The review highlights specific risks associated with EUS FNA, including complications like pancreatitis and bile duct leaks, and offers strategies to minimize these risks during the procedure.

In a study of 92 patients with small pancreatic cysts deemed benign on imaging, EUS-FNA successfully identified mucinous cysts in 41% of cases, aiding in patient management.

The cytologic examination showed a 99% negative predictive value for high-grade atypia, indicating that EUS-FNA is a reliable screening tool for determining the safety of conservative management of pancreatic cysts.

A nationwide survey of 101 medical professionals in Korea revealed that 79.2% routinely perform EUS-guided fine needle aspiration/biopsy for operable pancreatic solid masses, indicating its common use in clinical practice.

The study highlighted significant variability in techniques, such as needle types and sampling methods, suggesting a need for evidence-based guidelines to standardize practices and improve outcomes in EUS-FNA/FNB procedures.

In a study of 85 EUS-guided fine-needle aspirations (FNA) performed on pancreatic cysts, the use of single-dose piperacillin/tazobactam effectively prevented any cases of cyst infection, fever, or sepsis, demonstrating its efficacy as prophylaxis.

The study showed that administering piperacillin/tazobactam intravenously at the time of the procedure is safe and convenient, with only one patient experiencing a mild adverse event (nausea), indicating a low risk of complications.

EUS-FNA is generally a safe procedure with serious adverse events occurring in only 0.29% of cases, but certain risk factors can increase the likelihood of complications.

Key risk factors for adverse events include undergoing endoscopic retrograde cholangiopancreatography (ERCP) on the same day, performing more than 15 to-and-fro movements during the procedure, and a higher number of punctures, which can lead to pancreatitis and infection.

In a study of 332 fine needle aspirations (FNAs) from pancreatic masses, both FNAs and needle core biopsies demonstrated high sensitivity (89% for FNAs, 91% for core biopsies) and specificity (100% for both) in diagnosing pancreatic neoplasms.

Combining FNAs with needle core biopsies improved diagnostic yield, as it provided more cellular material for testing, leading to better detection of conditions like pancreatic adenocarcinoma.

In a study involving 67 patients, EUS-FNA combined with rapid on-site cytology demonstrated a high sensitivity of 94% and a specificity of 100% for diagnosing pancreatic cancer, making it a reliable method for early detection.

The use of rapid on-site cytology allowed for immediate evaluation of sample quality, which helped reduce the need for multiple sampling attempts, thus improving the efficiency of the diagnostic process.

In a study of 227 patients with pancreatic adenocarcinoma, both endoscopic ultrasound-guided fine needle aspiration (FNA) and fine needle biopsy (FNB) showed similar effectiveness in diagnosing malignancy, with rates of 69.4% for FNB and 65.5% for FNA.

The compatibility of cytology with histology was also comparable between the two methods, suggesting that FNB needles can be effectively used for cytological assessment in pancreatic lesions, just like FNA needles.

EUS-guided core biopsy using two passes showed comparable diagnostic performance to the gold standard EUS-guided FNA with on-site cytopathology, with sensitivity rates of 91.7% for core biopsy versus 83% for FNA.

The study involved 26 patients and found that the core biopsy method was more time-efficient, suggesting it could be a viable alternative to the more time-consuming FNA approach for diagnosing gastrointestinal lesions.

In a study of 202 patients undergoing EUS-FNA and EUS-FNB for pancreatic masses, the use of FNB needles was associated with a higher rate of minor bleeding, particularly in cystic pancreatic tumors, where 8.2% experienced minor bleeding.

Major bleeding was rare, occurring in only 0.7% of cases with solid tumors, indicating that while EUS-FNB may increase minor bleeding risks, it remains a safe procedure overall.

The new Franseen tip fine needle biopsy (FNB) device demonstrated significantly higher histology scores and a diagnostic yield of 96% for solid lesions, compared to 88% for the traditional fine needle aspiration (FNA) technique, based on a study involving 51 FNB and 50 FNA samples.

The FNB technique required fewer needle passes to achieve these results, indicating improved efficiency, although two patients experienced abdominal pain post-procedure, highlighting a need for monitoring safety.
