The VIPoma syndrome is also known as Verner-Morrison syndrome, watery diarrhea, hypokalemia, and hypochlorhydria or achlorhydria (WDHA) syndrome, and pancreatic cholera syndrome. metabolic acidosis loss of HCO3- normal anion gap. The condition is also alternately known as the Verner Morrison syndrome, pancreatic cholera syndrome or WDHA-syndrome. The eponym reflects the physicians who first described the syndrome. Imaging diagnostic techniques revealed a hypervascular tumor at the tail of the pancreas as well as a solitary liver metastasis. A vipoma is a non-beta pancreatic islet cell tumor secreting vasoactive intestinal peptide (VIP), resulting in a syndrome of watery diarrhea, hypokalemia, and achlorhydria (WDHA syndrome). fatigue VIPoma is also sometimes referred to as pancreatic cholera syndrome (PCS) or WDHA syndrome because of the three main symptoms that many patients experience: watery diarrhea, hypokalemia, and achlorhydria.

Tumor is localized with CT and endoscopic ultrasound. Metabolic acidosis,Acute renal failure,Hypovolemic shock & death are the complications . Stool output in patients with VIPomas ranges from 1 L to more than 3 L daily, leading to profound dehydration and acidosis. Abbreviation: WDHA, watery diarrhea, hypokalemia, acidosis. Other symptoms that are reported include flushing (which is one of the main features of carcinoid syndrome ), weight loss, lethargy, abdominal pain and bloating [12]. A right adrenal It was rhea, hypokalemia and achlorhydria (or metabolic acidosis); this collection of symptoms is also known as WDHA syndrome. Hyperkalemia (high potassium) reflects generally inadequate renal excretion, mobilization of potassium from the tissues, or excessive intake or administration. VIPomas are classically slow-growing, and previously reported cases consistently describe chronic diarrhoea and a 0020410 . Diagnosis is by serum VIP levels. In the three patients in which it was used, parachlorophenylalanine, an inhibitor of serotonin synthesis, improved the life‐threatening diarrhea.

Watery diarrhea, hypokalemia and hypochlorhydria or achlorhydria syndrome (WDHA) The acronym WDHHA (watery diarrhea [100%], hypokalemia [100%], achlorhydria) and acidosis from bicarbonate wasting is often present for 3 or 4 years before diagnosis, with volumes usually exceeding 6 to 8 liters of stool every 24 hours 8). Download. The VIPoma syndrome, also called the Verner-Morrison syndrome, pancreatic cholera, and the WDHA syndrome (for watery diarrhea, hypokalemia, and achlorhydria), results from an endocrine tumor, usually in the pancreas that ectopically secretes vasoactive intestinal polypeptide (VIP). Vasoactive intestinal peptide (VIP) secreting tumors (VIPoma) comprise several types of neuroendocrine tumor (NET), secreting VIP, which results in the "WDHA syndrome": watery diarrhea, hypokalemia, and achlorhydria ().Other presentations include hyperglycemia, metabolic acidosis, flushing, abdominal distention disproportionate to the nutritional state, and growth arrest (1-3). alcoholism, infectious enterocolitis, aldosteronism, renal tubular acidosis were reported to be possible causes of hypokalemic rhabdomyolysis. Case Report: Irreversible Watery Diarrhea, Severe Metabolic Acidosis, Hypokalemia and Achloridria Syndrome Related to Vasoactive Intestinal Peptide Secreting Malignant Pheochromocytoma. A vipoma is a non-beta pancreatic islet cell tumor secreting vasoactive intestinal peptide (VIP), resulting in a syndrome of watery diarrhea, hypokalemia, and achlorhydria (WDHA syndrome). Patients with WDHA syndrome may initially have an indolent course, or the disease may masquerade as other, more common conditions, leading to a delay in the diagnosis. A case of a metastasizing non-β-islet cell tumor of the pancreas with intractable watery diarrhea, hypokalemic acidosis, hypercalcemia, and alchlorhydria (WDHA syndrome) is presented. The VIPoma syndrome is also known as Verner-Morrison syndrome, watery diarrhea, hypokalemia, and hypochlorhydria or achlorhydria (WDHA) syndrome, and pancreatic cholera syndrome.

Watery diarrhea, hypokalemia, and achlorhydria (WDHA syndrome), also known as Vermer-Morrison syndrome or vipoma syndrome, was first reported by Verner and Morrison in 1958. The syndrome of watery diarrhea, hypokalemia, and achlorhydria (ie, WDHA syndrome) is a rare condition characterized by severe, watery diarrhea resulting from the oversecretion of vasoactive intestinal peptide (VIP) from non-beta pancreatic islet cells. Although only 11% of the patients in this series had bronchial carcinoid tumors, three of the four patients with severe diarrhea had . VIPomas symptoms. The diagnosis is established by determining the serum VIP level, tumor localization is determined by CT and endoscopic ultrasound.

This watery diarrhea, hypokalemia, achlorhydria (WDHA) syndrome caused by VIP-producing tumors is a well-known effect of VIPoma, but progression of the metabolic disturbance to the point of . VIPoma: Symptoms of Verner-Morrison or WDHA syndrome (ie, watery diarrhea, hypokalemia, achlorhydria, acidosis) are the result of the physiologic effects of overproduction of VIP by pancreatic endocrine neoplasms. Vasoactive intestinal peptide (VIP) secreting tumors (VIPoma) comprise several types of neuroendocrine tumor (NET), secreting VIP, which results in the "WDHA syndrome": watery diarrhea, hypokalemia, and achlorhydria ().Other presentations include hyperglycemia, metabolic acidosis, flushing, abdominal distention disproportionate to the nutritional state, and growth arrest (1-3).
