Ogilvie's syndrome presented with delirium in an older lady with corticobasal syndrome.

OBJECTIVE: Corticobasal syndrome (CBS) is one of an atypical parkinsonian syndromes characterized by extrapyramidal features as well as cortical involvement signs. A variety of factors may lead to delirium in older adults with chronic progressive life-limiting neurological illnesses like CBS. Ogilvie's syndrome (OS) is an acute colonic pseudo-obstruction in which abdominal distension, nausea, vomiting, and constipation can be seen. We report a case of OS identified as the underlying possible cause of delirium in an 80-year-old woman with CBS. We also discuss the importance of holistic approach which is essential to manage the underlying cause and to preserve the quality of life in particular for the frail geriatric population who potentially needs palliative care or already benefits from palliative care. METHOD: An older patient with CBS presented with symptoms similar to that of acute colonic obstruction and subsequently developed delirium. The patient was found to have colonic pseudo-obstruction (OS). RESULT: Neostigmin infusion was therefore given to treat it and delirium was resolved. SIGNIFICANCE OF RESULTS: To the best of our knowledge, clinical manifestation of delirium as OS in a patient with CBS has not been previously reported. OS may be superimposed to CBS in older patients, and OS in such patients may play a role as a precipitating factor for the development of delirium. Given the fact that CBS is progressive and rare neurodegenerative disease and almost all of these patients need palliative care, eventually, health-care professionals, especially in palliative care, should be aware of distinctive challenges of life-limiting chronic neurological illnesses, such as conditions that may lead to the development of acute colonic pseudo-obstruction because the rapid treatment of them prevents the use of potentially harmful drugs, surgical procedures, or inappropriate interventions.

Secretory diarrhea and hypokalemia associated with colonic pseudo-obstruction: A case study and systematic analysis of the literature.

BACKGROUND: Colonic pseudo-obstruction (CPO) is characterized by colonic distention in the absence of mechanical obstruction or toxic megacolon. Concomitant secretory diarrhea (SD) with hypokalemia (SD-CPO) due to gastrointestinal (GI) loss requires further characterization. AIM: To perform a systematic review of SD-CPO, report a case study, and compare SD-CPO with classical CPO (C-CPO). METHODS: We performed a search of MEDLINE, EMBASE, Cochrane, and Scopus for reports based on a priori criteria for CPO, SD and GI loss of potassium. An additional case at Mayo Clinic was included. RESULTS: Nine publications met inclusion criteria, with a total of 14 cases. Six studies had high, three moderate, and our case high methodological quality. Median age was 74 years (66-97), with 2:1 male/female ratio. Kidney disease was present in 6/14 patients. Diarrhea was described as profuse, watery, or viscous in 10 patients. Median serum, stool, and urine potassium concentrations (mmol/L) were 2.4 (range: 1.9-3.1), 137 (100-180), and 17 (8-40), respectively. Maximal diameter of colon and cecum (median) were 10.2 cm and 10.5 cm, respectively. Conservative therapy alone was effective in five out of 14 patients. Median potassium supplementation was 124 mEq/d (40-300). Colonic decompression was effective in three out of six patients; one had a total colectomy; three out of 14 had died. The main differences between SD-CPO and C-CPO were lower responses to treatments: conservative measures (35.7% vs 73.6%, P=.01), neostigmine (17% vs 89.2%, P<.001), and colonic decompression (50% vs 82.4%, P=.02). CONCLUSION: SD-CPO is a rare phenotype associated with increased fecal potassium and is more difficult to treat than C-CPO.

Ogilvie's syndrome-related right colon perforation after cesarean section: a case series.

The objective of this article is to discuss and report three cases of right colon perforation secondary to postcesarean Ogilvie's syndrome (OS; colonic pseudo-obstruction) requiring right hemicolectomy. We retrospectively reviewed the case notes of three patients who underwent caesarean section and postoperatively developed OS. OS is an uncommon problem in patients undergoing caesarean section. Abdominal X-ray and water-soluble contrast enema are the main diagnostic modalities. Drip-suck therapy along with endoscopic or pharmacological decompression should be performed in early stages. In a significant percentage of patients, diagnosis is delayed resulting in bowel ischemia and perforation requiring surgical resection and adding significant mortality/morbidity. We recommend our obstetric colleagues to involve surgical team in earlier stages to avoid surgery-related mortality and morbidity. We also advocate general surgeons to be aware of OS in patients after caesarean section and recommend a stepwise systematic approach toward the diagnosis and management of OS.

Intestinal Necrosis Associated with Orally Administered Calcium Polystyrene Sulfonate Without Sorbitol.

OBJECTIVE: To describe a case of extensive intestinal necrosis with oral intake of calcium polystyrene sulfonate without sorbitol. CASE SUMMARY: A 73-year-old woman was admitted to the emergency department with abdominal pain. Abdominal computed tomography (CT) scan showed widespread dilatation of the bowel. The diagnosis of acute colonic pseudoobstruction was made. On day 3, her serum potassium level rose to 5.6 mEq/L. It was treated with hydrocortisone 100 mg/day and calcium polystyrene sulfonate 15 g/day via nasogastric tube from day 3 to day 6. On day 6, the severe abdominal pain recurred, with abdominal tenderness. CT scan showed pneumoperitoneum and peritoneal effusion. At surgery, 2 lenticular jejunal perforations and an ischemic cecum were found. Microscopic findings indicated that the transmural abscess contained massive inflammatory infiltrate and the cecal mucosa showed ulceration and inflammation with a fibrinous and purulent coating. Small gray-purple or blue angulated crystals were embedded in the cecal and most of the jejunal mucosal ulcers. On day 19, the patient died of multiple organ failure after her third laparotomy. DISCUSSION: Ion-exchanging resins are given orally or by retention enema for the treatment of hyperkalemia. The most commonly used and best-established resin is sodium polystyrene sulfonate. However, it is known to promote colonic necrosis when sorbitol is also given or especially in patients with renal failure or postoperative ileus. Calcium polystyrene sulfonate is another ion-exchange resin. There are few reports of adverse effects in the literature. Our case is interesting for 2 reasons: the resin given was calcium polystyrene sulfonate and sorbitol was not used. CONCLUSIONS: Like sodium polystyrene sulfonate, calcium polystyrene sulfonate is an ion-exchanging resin that can promote bowel necrosis. We believe that it should not be used with sorbitol or when bowel transit time is slowed.

Splenic flexure volvulus in a child with chronic idiopathic intestinal pseudo-obstruction syndrome.

Splenic flexure volvulus in a child with chronic idiopathic intestinal pseudo-obstruction syndrome is extremely rare. Here we present a case report of this unusual condition in a 7-year-old girl. The splenic flexure volvulus was managed by pressure reduction from the cecal antegrade continence enema, after which elective resection of the splenic flexure and primary anastomosis were performed because she had similar attacks during 4 months after the first detorsion. Postoperatively she made an uneventful recovery. Possible factors of pathogenesis and therapeutic measures are discussed.

A new approach to the cure of the Ogilvie's syndrome.

The Authors describe a their own observation of 25 cases of acute colonic pseudo obstruction, better known as "Ogilvie Syndrome" with the objective to demonstrate that an early recognition and prompt appropriate therapy, better if conservative, can reduce the morbidity and the mortality of the Syndrome. The surgical therapy is reserved only to that cases in which the risk of perforation of the cecum represent an absolute indication to intervention.

Spontaneous pneumoperitoneum associated with colonic pseudo-obstruction.

Pneumoperitoneum is almost always pathognomonic of a perforated abdominal viscus requiring urgent surgical intervention. Spontaneous or non-surgical pneumoperitoneum is a rare clinical condition arising secondary to abdominal, thoracic, gynaecologic or idiopathic causes. In addition to good clinical judgement, an important component in the management process is to rule out other causes of pneumoperitoneum by performing appropriate investigations. We describe a 60-year-old man who presented with clinical features of pseudo-obstruction, following an injury to his back which was compounded by hypokalaemia. Roentgenography revealed massive pneumoperitoneum and colonic distension. As there were no overt clinical features of peritonitis, the patient was managed conservatively with parenteral nutrition and close observation. A water-soluble contrast enema and computed tomography of the abdomen were of no help in identifying the cause of his pneumoperitoneum but were helpful in eliminating the presence of hollow viscus perforation or an obvious inflammatory focus. The aetiology of pneumoperitoneum in our patient was most likely due to dissection of air through the distended colonic wall, secondary to large bowel pseudo-obstruction. The diagnosis of spontaneous or non-surgical pneumoperitoneum is one of exclusion and we stress the importance of relying on clinical parameters when managing such patients conservatively.

Intestinal obstruction and perforation--the role of the gastroenterologist.

Intestinal obstruction belongs to highly severe conditions in gastroenterology, namely from the viewpoint of quick and correct diagnosis as well as at determining rational and effective therapy. Etiological multifactorial characteristics leading to processes resulting in mechanical or dynamic obstruction of the intestine, often referred to as paralytic ileus, are undoubtedly serious factors influencing the accuracy of diagnosis and therapeutic approach. Digestive endoscopy is a mandatory method in the diagnosis of intestinal obstructions. Diagnostic endoscopy, colonoscopy in the involvement of the large intestine or enteroscopy in the case of incomplete obstruction of the small intestine are the methods indicated in the majority of obstructive intestinal lesions. Besides their diagnostic importance, they also enable an effective therapeutic approach which may immediately follow the diagnostic intervention. Besides endoscopy that--due to the nature of performance--belongs to invasive methods, the diagnosis of obstructive intestinal processes is unthinkable without the use of non-invasive imaging methods. Abdominal ultrasound examination, a widely applied method, provides--under optimal examination conditions--information, e.g., about the width of the intestinal lumen or about the intestinal wall thickness; however, the specificity of investigation is not always sufficient. Both specificity and sensitivity of exploration are increased by a plain X-ray of the abdomen supplementing the ultrasound examination. Better results are achieved when the abdominal cavity is inspected by means of spiral CT examination that is nowadays not fashionable but highly effectively applied in the modification of the so-called CT enteroclysis or CT colonography. The usage of magnetic resonance (e.g. virtual colonography) is similar, but its efficacy is lower than that of CT examination. From a gastroenterologist's perspective, endoscopic examination is the fundamental diagnostic and therapeutic method. However, endoscopic examination is initially limited by the cardiopulmonary state of the patient--in a number of cases, first the cardiopulmonary condition must be stabilized, dysbalance of water and mineral state must be restored, and only then can endoscopic investigation be carried out. The application of enteroscopy in small intestine disorders is only suitable in cases where air must be aspirated from the region of the stomach and mainly small intestine as it happens, for example, in acute intestinal pseudo-obstruction. The success of complex conservative therapy in these states is reached in 80% of the cases. In acute and complete intestinal obstruction, a surgical treatment performed in time is the only method. In these cases, the importance of identification of obstruction and timing of the intervention performance from the viewpoint of the patient's survival is explicitly the principal and life-saving concern. In acute intestinal obstructions developing in patients with malignant affection of the intestine, it is necessary to choose--according to the obstruction location and general state of the patient--either urgently performed surgery or palliative endoscopic intervention which is the reduction of the intestinal lumen of the growing tumor mass and following insertion of a drain. This method also concerns lesions localized in the left half of the abdominal cavity, i.e. in the region of the rectosigmoid and descending part of the colon. Most patients in whom acute intestinal obstruction developed on the basis of malignant disease are risk and polymorbid subjects, and acute surgical intervention may be either impracticable or highly stressing. In such cases it is therefore helpful to insert a drain and to bridge the obstructed area after restoring the cardiopulmonary state including adjustment of the aqueous and mineral environment. Later, the performance of an elective surgical intervention is safer. Another alternative before inserting a drain is the dilatation of the stenotic site by means of a balloon, followed by stenting. Up until today, various types of intestinal drains have been introduced--they have always been self-expanding metallic stents. Just the application of self-expanding stents in patients with malignant intestinal obstruction and the endoscopic possibility of dilatations of benign intestinal obstructions with dilatation balloons are the most significant therapeutic contributions of digestive endoscopy in these states.

Seudoobstrucción aguda del colon: síndrome de Ogilvie / Acute colonic pseudo obstruction: Ogilvie's syndrome

Se presenta la experiencia en el diagnóstico y tratamiento de 24 pacientes complicados con una seudoobstrucción de colon en un período de 9 años, 95 por ciento de las mujeres, con un promedio etario de 37 años. La cesárea fue la intervención previa en el 63 por ciento de los casos y los signos clínicos más destacados fueron dolor y la distensión abdominal progresivos. La radiografía simple de abdomen es el examen de mayor utilidad en este cuadro, tanto en el diagnóstico como en la evolución y control del tratamiento instaurado. El tratamiento médico resolvió el cuadro en 11 casos y la colonoscopia aspirativa en 2. Los factores pronósticos más relevantes del síndrome de Ogilvie son la patología de base, la ruptura neumática del ciego y la edad, lo que explica la baja mortalidad de esta serie, 6 por ciento, compuesta en su mayoría por pacientes jóvenes y sin patología asociada. El seguimiento a largo plazo del 87 por ciento de los pacientes no logró demostrar alteraciones anatómicas o funcionales del colon
