“…The open surgical approach was replaced by laparoscopic techniques. The substantially high diagnostic accuracy stayed almost unchanged and recovery time became shorter, however general anesthesia was constantly required 6,8 . Percutaneous approach using imaging methods guidance provides the next possibility for obtaining tumorous tissue samples, this time without the necessity of general anesthesia.…”

Aims. To retrospectively evaluate the technical features, efficacy, accuracy, appropriate complications, and relationships among monitored parameters of computed tomography-guided biopsies of the retroperitoneum-located processes. Methods. From December 2008 to December 2018, 208 percutaneous biopsy procedures for tumors, sized 14-190 mm in diameter (median size 57.5 mm), were performed on patients with suspected retroperitoneal tumorous process on imaging examinations. The patients were men in 124 cases and women in 84 cases, aged 20 to 90 years (median age 63.2 years). Skin to lesion distance was variable; from 43 cm to 178 cm (median length 108.5 cm). Results. In 202 cases (97.1%) results were true positive or true negative; only 6 interventions (2.9%) were histologically false negative and had to be confirmed surgically. DLBCL and metastatic disease to the retroperitoneal lymphatic nodes were the most common diagnoses (23.1% each); lymphoma types were verified in 40.9% of cases. 7 complications in total were revealed, 6 of which were minor hemorrhages, and in one case ureteral injury was detected. A statistically significant relationship between the hypervascular process and complication incidence (P=0.00166) and needle gauge (P=0.01427) was identified. Conclusion. Percutaneous CT-guided biopsy performed in patients with a suspected retroperitoneal tumorous process had a high accuracy in establishing the correct diagnosis including histological subtyping. Simultaneously, the complication rate was low.

“…Historically, establishing the diagnosis was associated with a surgical procedure using laparotomy or laparoscopy 6 . The advantage was enormously high diagnostic accuracy, on the other hand this approach is demanding for patients who also carry all risks connected to general anesthesia.…”

“…Algunos autores realizan estudio histológico por congelación y después de confirmar adecuada muestra, terminan la cirugía 20 . Este recurso puede ser útil; sin embargo, no es el protocolo en nuestra institución y como hemos descrito, todas las muestras fueron adecuadas para diagnóstico, resultado que nos parece relevante, pues la confirmación histológica del diagnóstico es el objetivo fundamental del procedimiento y está relacionado con la cantidad y calidad de la muestra obtenida.…”

Introducción: La biopsia ganglionar retroperitoneal es un procedimiento frecuentemente requerido en el estudio de neoplasias; resulta deseable optimizar su rendimiento con baja morbilidad. Este trabajo describe la utilidad y complicaciones de biopsias ganglionares retroperitoneales por laparoscopia en una institución oncológica de Latinoamérica.Material y métodos: Cohorte retrospectiva de pacientes con biopsia ganglionar retroperitoneal o mesentérica laparoscópica entre 2011 y 2021 en el Instituto Nacional de Cancerología, en Bogotá, Colombia. Se recogieron datos demográficos, quirúrgicos, complicaciones y mortalidad a 30 días, resultados histopatológicos y su rol en la clínica.Resultados: Se incluyeron 41 pacientes; 73% con diagnóstico de malignidad, principalmente linfoma. La indicación fue mayormente sospecha de recaída, seguida por sospecha de enfermedad hematológica de novo. Siempre se obtuvo tejido adecuado y suficiente para diagnóstico histológico. Requirieron conversión a laparotomía cinco pacientes (12%). No hubo complicaciones Clavien-Dindo III /IV ni mortalidad a 30 días. Se presentó morbilidad grado I o II en 3 casos (7%) y un incidente intraoperatorio grado III.Conclusión: La naturaleza invasiva y el carácter diagnóstico de la biopsia retroperitoneal laparoscópica, constituyen un desafío frecuente en la práctica del cirujano general. La planeación estratégica e individualizada y la técnica quirúrgica depurada son las claves para lograr el máximo rendimiento, con baja morbimortalidad.

“…Since the tumor was adjacent to the abdominal aorta and intestines, the patient did not undergo ultrasound-or CT-guided biopsy, given the anticipated difficulty in performing either procedure. 5 Instead, laparoscopic resection of the para-aortic tumor was planned, which would also allow a definite diagnosis.…”

Introduction: Extra-adrenal pheochromocytomas (paragangliomas) are neuroendocrine tumors derived from extra-adrenal chromaffin cells. Although laparoscopic resection of adrenal pheochromocytomas is a common procedure, there are few reports of the use of this approach in extra-adrenal para-aortic paragangliomas. Here, we report the case of a patient with a subclinical functioning para-aortic paraganglioma that was successfully resected laparoscopically. Case presentation: A 58-year-old man was referred to our department for treatment of a para-aortic tumor after endoscopic submucosal dissection of early-stage colorectal cancer. Positron emission tomography-computed tomography showed abnormal accumulation by the para-aortic tumor. During its laparoscopic resection, the patient's blood pressure unexpectedly rose to over 180 mmHg, which suggested that the tumor was a paraganglioma. The diagnosis was confirmed by immunohistochemical staining, which showed chromogranin-positive cells forming a Zellballen pattern. The operation was successfully completed, and the patient's postoperative course was uneventful. Conclusion: Laparoscopic resection may be a suitable procedure for the treatment of retroperitoneal paraganglioma.
