An important fact is that the giant villous adenomas may excrete large quantities of mucus and potassium, which can produce mucus diarrhea and electrolytic alterations. McKittrick-Wheelock syndrome, which is a disorder characterized by fluid and electrolyte depletion, is caused by a secretory colorectal tumor [ 32 ] Villous adenomas rarely cause a secretory diarrhea syndrome. The tumor usually is located at the rectosigmoid or rectum and often is 3-4 cm in diameter. Stool volumes of 350-3000 mL are reported.. A case of villous adenoma of the rectum with severe electrolyte abnormality is presented. Replacement therapy required the administration of both potassium and sodium salts

Villous adenomas are more likely to progress to carcinoma than are simple tubular adenomas of the same size. Extremely large adenomas can result in electrolyte imbalance because of the large amount of mucus secreted. These lesions are usually very soft—almost gelatinous—and frondlike; hence the term villous The electrolytes which are affected are particularly sodium and potassium. Not all patients with villous tumors show fluid and electrolyte imbalance (2, 8, 11, 22); when present, it is a late complication (19, 26) leading to death in some cases (7, 15, 18). This syndrome was apparently first recognized by McKittrick and Wheelock (16) A rare combination of severe volume depletion and electrolyte imbalance caused by a rectal villous adenoma is often referred to as the McKittrick-Wheelock syndrome. Patients usually seek medical care because of chronic hypersecretory diarrhea and display renal failure, metabolic acidosis, hyponatremia, and hypokalemia One of the most common electrolyte imbalances is hyponatremia, low levels of sodium in the blood. 1  Other particularly important types are elevated sodium (hypernatremia), abnormalities in potassium (hypokalemia or hyperkalemia), abnormalities in calcium (hypercalcemia or hypocalcemia), and imbalances in magnesium (hypermagnesemia or hypomagnesemia). 2 McKittrick-Wheelock syndrome describes the condition of extreme electrolyte and fluid depletion caused by large distal colorectal tumours, usually the benign villous adenoma. Patients generally present critically unwell with severe hyponatraemia, hypokalaemia and/or acute kidney injury

At the age of 50, serious electrolyte imbalance was manifested by neuromuscular symptoms including convulsions and coma, and the diagnosis of villous adenoma was made. The soft tumor, its surface covered with villous projections, was actively secreting mucus and completely lined the rectum A case of villous adenoma complicated by severe fluid and electrolyte depletion has been reported. Some unique features of the villous adenoma and the treatment of the electrolyte depletion syndrome have been discussed. Several points should be stressed in relation to this syndrome: (1) Villous adenomas are easily missed on digital examination because of their soft consistency villous adenoma it is important to set the diagnosis carefully.

EISENBERG HL , KOLB LH , YAM LT , GODT R Ann Surg , 159:604-610, 01 Apr 196 Discussion. McKittrick-Wheelock syndrome was described in 1954 and is a rare complication of villous adenoma.1 It is typified by large-volume secretory diarrhoea, prerenal acute renal failure, and severe electrolyte dysfunction (primarily hyponatraemia, hypochloraemia, hypokalaemia and metabolic acidosis). The causative lesion is usually in the rectosigmoid and is normally over 4 cm in. Two years later a severe electrolyte imbalance developed that was attributed to irradiation proctitis. In view of the recent report by Starr and his associates of a case of villous adenoma of the colon associated with severe hypopotassemia, 1 the question of the possibility that the electrolyte imbalance might be a complication of the primary.

McKittrick-Wheelock syndrome (MKWS) is caused by a villous tumor of the rectosigmoid colon with hypersecretion of mucus containing electrolytes. Complete resection of the tumor is needed to cure this disease. Transanal total mesorectal excision (TaTME) is currently a promising treatment for lower rectal tumor because of the reliability of its resection margin especially in bulky tumor In a review of the literature on possible mechanisms of fluid and electrolyte imbalances, the electrolyte composition of mucin secreted by abnormal cells within the causative lesion is of interest. Whereas a normal bowel absorbs sodium and water and secretes potassium, segments of intestine affected by villous adenoma have been found to secrete.

Other issues with the gastrointestinal tract that may contribute to poor potassium levels in the body include vomiting, villous adenoma and an ileostomy. In some cases, the cause of low potassium levels may lie with the kidneys. Renal tubular acidosis, low magnesium levels in the body, and high levels of aldosterone in the body are all possible.

Villous adenomas have been described as broad, shaggy lesions with a cauliflower-like surface. 5 They are frond-like and are comprised of a core of fibrovascular lamina propria lined with mucin-secreting columnar epithelium that, in larger lesions, can secrete copious quantities of mucinous fluid. 1,5,8 Adenoma size is one of the most important.

electrolyte imbalance, and giant rectosigmoid tumor. The distal location of the tumor prevents reabsorption of abnormally secreted electrolyte in normal colonic mucosa. This is a rare disease, which occurs only in 0.27-2.4% of villous adenomas representing 3-6% of colonic tumors [2, 7-9]. The size of tumors with MKW Biopsy revealed a villous adenoma. On the basis of these results, a villous adenoma associated with electrolyte depletion syndrome was diagnosed. After electrolyte abnormalities were improved by fluid replacement therapy, laparoscopic abdominoperineal resection was performed. The surgically resected specimen was a circumferential villous tumor. Acid-base, electrolyte, and metabolic disturbances are common in the intensive care unit (ICU). Indeed, critically ill patients often suffer from compound acid-base and electrolyte disorders. Successful evaluation and management of such patients requires recognition of common patterns (e.g., hypokalemia and metabolic alkalosis), and an ability.

Background. McKittrick-Wheelock syndrome (MWS) is a rare cause of acute kidney injury (AKI) with electrolyte depletion (ED). First described in 1954 by McKittrick and Wheelock, the syndrome is defined by the constellation of ED, AKI and secretory diarrhoea driven by a large neoplastic lesion of rectum or rectosigmoid colon, typically a villous adenoma electrolyte imbalance (pre-renal acute renal failure, metabolic acidosis, neurological signs and symptoms secondary to ionic imbalance); b) copious hypersecretory mucorrhea; and c) presence of a giant villous adenoma of the rectum or rectosigmoid.

Cardiovascular Physiology The gastrointestinal tract is a slumbering giant with regard to acid-base homeostasis. Large amounts of H + and HCO 3 − traverse the specialized epithelia of the various components of the gut every day, but under normal conditions, only a small amount of alkali (approximately 30 to 40 mmol) is lost in the stool (1,2).In contrast to the kidney, acid and alkali transport in the gut is adjusted. Hypokalemia is serum potassium concentration < 3.5 mEq/L (< 3.5 mmol/L) caused by a deficit in total body potassium stores or abnormal movement of potassium into cells. The most common cause is excess loss from the kidneys or gastrointestinal tract. Clinical features include muscle weakness and polyuria; cardiac hyperexcitability may occur with severe hypokalemia Diffenbaugh WG, Strohl EL, Anderson RE, et al: Papillary (villous) adenomas: Location in rectum and colon with electrolyte imbalance.
