EUS-LB will be performed using a 22 g FNB needle. Specimens obtained from each pass will be placed in a separate biopsy jar. If the third pass does not result in sufficient diagnostic material, a 19 G will be used. A maximum of 3 passes will be made using the alternate needle. The total number of passes with the 22 G needle and the 19 G needle is 6. Data will be collected about the procedure and the performance of the needles for each procedure.

22 gauge needle liver biopsy

Muhammad Hasan, MD

This is a prospective study to determine the optimal technique for obtaining liver tissue with a smaller caliber (22 gauge) needle and whether a good core biopsy can be obtained without the use of suction and secondly to determine the diagnostic yield and safety of 22 g Fine Needle Biopsy needle for liver biopsy.

Liver biopsy (LB) has historically been performed by percutaneous route without image guidance (blind biopsy). However, in the last several years there has been more reliance on image guidance ultrasound-guided (USG) or computed tomography (CT) to direct the needle into the liver with the hope of limiting complications. Other ways of performing liver biopsy are transjugular fluoroscopy guided approach when percutaneous route is deemed not safe because of coagulopathy or ascites. Surgical LB (either laparoscopic or open) is yet another way of obtaining liver tissue.

Endoscopic ultrasound guided liver biopsy (EUS-LB) is proposed as a newer method that may offer several potential advantages over existing techniques for attaining liver tissue. It can be performed in an outpatient setting and offers the comfort of sedation and analgesia. Endoscopic Ultrasound (EUS) provides high resolution images of left lobe of the liver and a good portion of the right lobe of the liver. This coupled with Doppler capability the biopsy needle can be safely directed into the liver for sampling under real time image guidance. Intervening structures such as pleura, bowel loops and gallbladder can be easily seen by EUS and thus avoided that further decreases the risk of adverse events. It has been recognized that sampling error can lead to diagnostic inaccuracy of a biopsy from a single site. As compared to USG or CT scan the EUS allows easy and safe biopsy of both left and right lobes of the liver during same setting, potentially addressing concerns about sampling error.

The cost of the endoscopic procedure is the main expense of EUS-LB. Thus this approach is best used for patients requiring EUS for evaluation of elevated liver tests. If no obstructive lesion is identified by EUS that will require endoscopic retrograde cholangiopancreatography (ERCP) then it would cost-effective to perform EUS-LB during the same setting without much additional time and risks. This approach can spare the patient the additional discomfort and expense of a second dedicated LB procedure by any of the other available techniques (percutaneous, transjugular etc.). In such setting the equipment costs for the EUS-LB will mainly include only the Fine Needle Biopsy (FNB) needle, which is similar in expense to the cost of needles for the transjugular or percutaneous approach.

The traditionally used transcutaneous LB needle is 16 gauge (G) while largest EUS biopsy needle is 19 G. The smaller size of the needle is expected to decrease the complications rate (mainly pain and bleeding) even further. Many studies using a 19 G Tru-cut biopsy or Fine Needle Aspiration (FNA) needle to acquire liver tissue have obtained specimens adequate for histologic diagnosis but there has been a wide range of specimen adequacy (19-100%). The 19 G Tru-cut biopsy needle has been associated with several technical difficulties that could reflect negatively on tissue adequacy.

While it is easy and straight forward to biopsy the left lobe of the liver with any EUS needle. The 19 G needle is a large bore needle for EUS use and it is sometimes difficult to attain an adequate position for biopsy specially in duodenum where scope is torqued and this is the only area of access to right lobe.

In this study the investigators will use a 22 G needle. Smaller caliber of the needle would not only make it technically easier to access right lobe of the liver through the duodenum, it is also expected to decrease the risks further due to smaller size. Also, the 22 G EUS-FNB needle has three cutting points at the cutting edge of the needle that provide stability at puncture while the high quality, fully formed heels are designed to maximize tissue capture and minimize fragmentation, that would result in attaining a good histological specimen, a main stay for liver biopsy.

Eligible participants in Arm A enrolled in this imaging study will: be older than 18, have metastatic colorectal cancer with at least one hepatic lesion, and be treated with FOLFOX in combination with bevacizumab.

Eligible participants in Arm B enrolled in this imaging study will: be older than 18, must have prior histological documentation of any types of cancer with metastasis to the liver, and must be in stable treatment conditions prior to and between scans.

Participants will receive two (2) dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) prior to chemotherapy and one (1) DCE-MRI after the first cycle of chemotherapy. Participants will be followed for up to 2 years after the initiation of chemotherapy or until disease progression.

The objectives for this study include:

* Testing a unique way of imaging people with colorectal cancer and other cancers that has spread to the liver using magnetic resonance imaging (MRI);
* Seeing if the MRI process can be used across multiple imaging platforms;
* Determining whether the results of the imaging can be reproduced;
* Reviewing how MRI results relate to cancer response to combination therapy and to clinical endpoints.

This study will investigate the use of projection reconstruction dynamic contrast-enhanced MRI (DCE-MRI) as a surrogate marker of tumor vascularity in patients treated with the antiangiogenic agent bevacizumab. DCE-MRI is gaining popularity as a method to assess the functional response of tumors to agents targeting the vascular endothelial growth factor (VGEF) pathways. DCE-MRI measurements have been proposed as a non-invasive measure of both tumor biologic activity and (in the case of antivascular therapy) early response to treatment. A number of phase I and II studies demonstrate the ability for DCE-MRI to detect perfusion changes associated with tumor biologic response to vascularly targeted agents. It has been suggested that pre-treatment DCE-MRI might identify tumors with high intrinsic perfusion and that these tumors will be more likely to respond to antivascular-based therapies. However, the current use of DCE-MRI in clinical settings is challenging. Trade-offs between spatial coverage, time, and spatial resolution make this technique difficult to implement in human studies and may limit its reliability. The use of projection reconstruction-based acquisition can mitigate the need for these trade-offs and can simultaneously provide high temporal and spatial resolution data for DCE-MRI analysis.

Ultrasound guided liver resection

The search for communicating veins (CVs) between adjacent hepatic veins (HVs) has drawn its rationale from living donor liver transplantation (LDLT). Parenchymal sparing procedures although HVs are resected suggest that probably their presence is underestimated.

Taking profit from new improvements in ultrasound technology the investigators aim to better estimate the rate of CVs in a consecutive series of patients in whom resection of one HV at caval confluence is needed.

The search for communicating veins (CVs) between adjacent hepatic veins (HVs) has drawn its rationale from the need of reducing the risk of incomplete blood outflow in the medial portion of the hemiliver without the middle hepatic vein (MHV) in living donor liver transplantation (LDLT). However, only 24% of patients seems having CVs based on the findings of color-Doppler intraoperative ultrasound (CD-IOUS) exploration. On the other hand the safety of parenchymal sparing procedure despite HV resection let suppose that CVs are probably more frequent than expected.

Certainly, better in vivo knowledge of the rate of CVs and their direct detection would consolidate and probably further expand parenchymal sparing techniques. Taking profit from new advancements in ultrasound technology we have carried out the present study with the aim of better estimating the rate of CVs in a consecutive series of patients in whom resection of one HV at caval confluence was needed.
