EUS-guided FNA of peritoneal carcinomatosis in patients with unknown primary malignancy

Diagnosis of tuberculous peritonitis using endoscopic ultrasound-guided fine-needle aspiration biopsy of the peritoneum

“…The presence of ascites helps in visualizing small peritoneal implants thus making EUS tissue sampling easier. Transgastric EUS has the disadvantage of not reaching the lower abdominal and thereby cannot detect TBP-related pathologies above the pelvic region (13). All patients in our study had no additional pathologies besides ascites and peritoneal deposits on CT and EUS.…”

Diagnosis of Metastatic Breast Cancer to an Intraabdominal Lymph Node by Endoscopic Ultrasound

“…However, it has also been utilized for sampling ascites, the adrenal glands, as well as lymph nodes surrounding the esophagus, stomach, proximal duodenum, and rectum to aid in the diagnosis of malignancy [2, 3, 4, 5]. While EUS has previously been shown to be useful in diagnosing metastatic breast cancer to the esophagus, mediastinum, pancreas, stomach, and peritoneum [2, 3, 4, 6, 7, 8], there have been no reports to our knowledge describing the use of EUS for diagnosing an intraabdominal lymph node recurrence of breast cancer as in this case. Since the diagnosis of metastatic breast cancer was established by EUS, the patient was able to receive adjuvant therapy without undergoing more invasive procedures to sample the concerning pulmonary nodule.…”

Diagnostic and therapeutic strategies in peritoneal carcinomatosis from breast cancer – literature minireview

“…The biopsy can be taken through surgical approach such as laparotomy or laparoscopy, or, more recently, through a less invasive procedure such as ultrasound guided biopsy or fine needle aspiration. An interesting study focused on this subject originates from Peter et al from Alabama, United States of America 10 . The authors reported a series of four patients submitted to endoscopic ultrasound and biopsy by using trans-gastric or trans-duodenal approach.…”

“…Among these cases, in one patient breast cancer origin was found for the peritoneal lesions; it was the case of a 54-year-old patient suspected for ovarian cancer presenting for mild ascites, peritoneal carcinomatosis and possible ovarian tumour. The fine needle aspiration obtained through echo-endoscopy raised the suspicion of a poorly differentiated, metastatic carcinoma, so the patient was submitted to total hysterectomy with bilateral adnexectomy and omentectomy, the histopathological studies revealing the presence of tumoral cells at the level of the uterus, both ovaries and cervix, suggestive for metastatic breast cancer 10 .…”
