ABSTRACT

The effect of plugging the puncture channel with a mixture of hemocoagulase injection on the complications of CT-guided percutaneous transthoracic need biopsy (PTNB) was discussed. The medical records of PTNB were retrospectively studied from June 2017 to May 2022. In the study, the puncture channel of 626 patients were blocked, while remain 681 patients' were not. The Mantel Haenszel method performed layered analysis and evaluated the correlation of adjusted confounding factors. The Odds Ratio and its 95% confidence interval were calculated using the Woof method. The incidence of high-level pulmonary hemorrhage was significantly reduced in patients with lesions ≤ 2 cm and different needle lengths. Patients with different pleural-needle tip angle and perineedle emphysema were blocked, and the incidence of pneumothorax and thoracic implants was significantly reduced. Through puncture channel plugging, the incidence of pulmonary hemorrhage, pneumothorax and thoracic catheterization of PTNB under CT guidance was reduced.

ABSTRACT

The overall incidence of rectal gastrointestinal stromal tumor (RGIST) has risen, but it remains a rare disease. Furthermore, tumor rupture is associated with poor prognosis. The present study reported a rare case of RGIST with indolent biological behavior. The biological behavior of this RGIST was analyzed and its malignant potential was evaluated using a guideline-based risk stratification assessment. The patient was diagnosed with a rectal tumor at the Third Affiliated Hospital of Qiqihar Medical University (Qiqihar, China) in April 2020 and a partial resection biopsy was then performed. This resection counts as a rupture. The biopsy confirmed RGIST and the patient refused further examination and treatment due to economic concerns. However, the patient survives with no tumor progression and metastasis until now, May 2022. In conclusion, based on the present case, tumor rupture in indolent RGIST is not necessarily associated with poor outcome.
