[Subclinical Pheochromocytoma: The Surgeons Point fo View - A Single-Institution Experience]
Khirurgiia
|February 1, 2018
Summary
Silent pheochromocytomas, often undiagnosed, can lead to longer surgeries and more intraoperative complications. Early evaluation and treatment are crucial for patients with these rare neuroendocrine tumors.
Area of Science:
- Endocrinology
- Surgical Oncology
- Nephrology
Background:
- Pheochromocytoma is a rare neuroendocrine tumor with often non-specific or absent symptoms, leading to underdiagnosis.
- Subclinical pheochromocytoma presents a diagnostic challenge, as many cases remain undetected during a patient's lifetime.
- This study focuses on the institutional experience with silent pheochromocytomas, detailing their preoperative characteristics, intraoperative management, and postoperative outcomes.
Purpose of the Study:
- To analyze the preoperative characteristics, intraoperative management, and postoperative complications of silent pheochromocytomas.
- To highlight the challenges in diagnosing and managing pheochromocytomas that lack typical clinical presentation.
- To evaluate the surgical outcomes in patients with asymptomatic pheochromocytoma.
Main Methods:
- Retrospective analysis of 104 patients who underwent surgery for pheochromocytoma between 1978 and 2010.
- Identification and detailed review of 11 patients diagnosed with silent pheochromocytoma (no clinical symptoms).
- Assessment of diagnostic indications, surgical procedures, hospital stay, and intra- and postoperative complications.
Main Results:
- Eleven out of 104 surgically treated pheochromocytoma patients were asymptomatic.
- Patients with silent pheochromocytoma experienced significantly longer operative times (p=0.04).
- A higher incidence of intraoperative complications, including increased blood loss and transfusion requirements, was observed in the silent pheochromocytoma group (p=0.02), with no significant difference in postoperative complications.
Conclusions:
- Pheochromocytoma presentation is highly variable, underscoring the importance of thorough evaluation.
- Patients with incidentally discovered pheochromocytomas requiring surgery necessitate close preoperative assessment and medical management.
- Optimizing preoperative care is essential for achieving favorable outcomes in patients with silent pheochromocytoma.

01:29Econometric Views (EViews)
606
Econometric Views, often stylized as EViews, is a package that merges statistical analysis with econometric studies. It is designed to provide tools for time series analysis, forecasting, and econometric model simulation. The software originated from MicroTSP software and has evolved significantly since its inception in 1981. The history of EViews is marked by a continuous effort to enhance its computational speed and user interface. It was initially developed for large computing systems but...

01:27Cranial Bones: Lateral View
7.3K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:12What is an Experiment?
19.2K
An experiment is a planned activity carried out under controlled conditions. The purpose of an experiment is to investigate the relationship between two variables. When one variable causes change in another, we call the first variable the explanatory or independent variable. The affected variable is called the response or dependent variable. In a randomized experiment, the researcher manipulates values of the explanatory variable and measures the resulting changes in the response variable. The...

01:24Revisionist Views of Adolescent and Adult Cognition
319
A revisionist approach to Jean Piaget's theory of cognitive development has brought new insights that challenge and reinterpret his established ideas. Piaget proposed that the formal operational stage, emerging in adolescence, represents the culmination of cognitive maturity. During this stage, individuals are said to develop abstract thinking, engage in systematic problem-solving, and show a form of egocentrism, believing others are as preoccupied with their behavior as they are...

01:14Cranial Bones: Superior and Posterior View
8.0K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

7.0K
In a beam of charged particles created by a heated cathode, the particles move at different speeds. However, many applications need a beam with uniform particle speeds. An arrangement known as a velocity selector uses electric and magnetic fields to pick particles with a particular speed from the beam.
A particle with charge q, speed v, and mass m enters an area from the top, where the magnetic and electric fields are perpendicular both to the particle's motion and to one another. The magnetic...
