“…Alternatives to avoid traversing vital organs during biopsy include hydrodissection and pneumodissection. [ 13 14 ] With these techniques, either a 0.9% saline solution (in hydrodissection) or air (in pneumodissection) is injected to displace the parietal pleura and expand the posterior paravertebral space while simultaneously advancing the coaxial needle carefully under CT control. The location of the lesion can also be confirmed with intravenous contrast administration to improve the diagnostic accuracy of the procedure.…”

Background/Aims:The purpose of this study is to report our results using a computed tomography (CT)-guided fat transversing coaxial biopsy technique for pancreatic lesion biopsy that avoids major organs and vessels. We retrospectively reviewed the records of patients referred to our department for pancreatic mass biopsy.Patients and Methods:The records of patients (from June 2008 to August 2014) in whom biopsy was performed under CT guidance with a coaxial needle using a fat transversing technique were reviewed. Patient demographic data and biopsy outcomes were collected. We aimed to compare differences between lesion size and biopsy outcome, the independent two-samples t-test was used.Results:A total of 122 patients who underwent 17-G coaxial needle biopsy were included. The mean pancreatic lesion size was 3.2 cm, and in 30 patients it was more than 4 cm. The majority of lesions were located in the head of the pancreas (44.3%). No transorgan biopsies were performed. In most patients, the biopsy was performed via a fat traversing detour route (93.4%), and a successful diagnosis was made based on the biopsy outcome in 96.7% patients. Complications occurred in five patients (4.1%); three of the patients developed a fever, and two developed pancreatitis. All patients recovered with symptomatic treatment.Conclusion:CT-guided coaxial core biopsy of pancreatic lesions using a fat detour route appears to be a safe and effective method for obtaining pancreatic lesion biopsies with a high success rate and low complication rate.

“…Ante el avance de la aguja, se deberá corroborar la posición de las asas intestinales (especialmente si la BP se realiza con TC). 1 En caso de ser necesario, la hidrodisección o la neumodisección pueden ser útiles para desplazarlas [25][26][27][28] .…”

Las biopsias percutáneas a nivel de la pelvis plantean un desafío dada la compleja anatomía regional. El conocimiento de las estructuras afectadas y el tipo de lesión a intervenir son algunos de los aspectos que van a influenciar la técnica que se utilice. Se han propuesto distintas vías de abordaje, pero aún carecen de sistematización. El objetivo de este artículo es destacar accesos seguros ejemplificando con casos ilustrativos de nuestra institución. Además, agregamos comentarios basados en nuestra experiencia.

“…Several techniques such as trans-hepatic, trans-gastric, hydrodissective, and pneumodissective approaches have been developed to avoid damage to visceral organs [15,16,17,18]. Over the past 10 years, our institute has developed a fat-transversing route approach for pancreatic biopsies which is able to reach most tumors in the pancreas without penetrating organs or vessels.…”

Percutaneous Computed Tomography-Guided Coaxial Core Biopsy for the Diagnosis of Pancreatic Tumors

Endoscopic, ultrasound-guided tissue acquisition (EUS-TA) with rapid on-site evaluation is recommended as a first choice in the diagnosis of pancreatic lesions. Since EUS facilities and rapid on-site evaluation are not widely available, even in medical centers, an alternative for precise diagnoses of pancreatic tumor is warranted. The percutaneous computed tomography-guided, core needle biopsy (CT-CNB) is a commonly applicable method for biopsies. Our institute has developed a fat-transversing approach for pancreatic biopsies which is able to approach most tumors in the pancreas without penetrating organs or vessels. Herein, we report a 15-year experiment of pancreatic tumor coaxial CT-CNB in 420 patients. The success rate of tissue yielding by the technique was 99.3%. The overall sensitivity, specificity, and accuracy were 93.2%, 100%, and 93.4%, respectively. The diagnostic accuracy could be increased to 96.4% in 2016–2018 (after the learning curve period). The overall complication rate was 8.6%. Neither life-threatening major complications, nor seeding through the biopsy tract, were observed. Our study supported the hypothesis that CT-CNB could be a complementary option for diagnostic tissue acquisition in patients with unresectable or metastatic pancreatic tumors when EUS-TA is either unsuitable or unavailable.
