Ogilvie's syndrome after lower extremity arthroplasty. (1/26)

OBJECTIVE: To alert surgeons who perform arthroplasty to the possibility of acute colonic pseudo-obstruction (Ogilvie's syndrome) after elective orthopedic procedures. To identify possible risk factors and emphasize the need for prompt recognition, careful monitoring and appropriate management so as to reduce morbidity and mortality. DESIGN: A case series. SETTING: A university-affiliated hospital that is a major referral centre for orthopedic surgery. PATIENTS: Four patients who had Ogilvie's syndrome after lower extremity arthroplasty. Of this group, 2 had primary hip arthroplasty, 1 had primary knee arthroplasty and 1 had revision hip arthroplasty. MAIN OUTCOME MEASURES: Morbidity and mortality. RESULTS: In all 4 patients Ogilvie's syndrome was recognized late and required surgical intervention. Two patients died as a result of postoperative complications. CONCLUSIONS: Our case series identified increasing age, immobility and patient-controlled narcotic analgesia as potential risk factors for Ogilvie's syndrome in the postoperative orthopedic patient. Prompt recognition and early consultation with frequent clinical and radiographic monitoring are necessary to avoid colonic perforation and its significant associated death rate.  (+info)

Neostigmine for the treatment of acute colonic pseudo-obstruction. (2/26)

BACKGROUND: Acute colonic pseudo-obstruction -- that is, massive dilation of the colon without mechanical obstruction -- may develop after surgery or severe illness. Although it may resolve with conservative therapy, colonoscopic decompression is sometimes needed to prevent ischemia and perforation of the bowel. Uncontrolled studies have suggested that neostigmine, may be an effective treatment. METHODS: We studied 21 patients with acute colonic pseudo-obstruction. All had abdominal distention and radiographic evidence of colonic dilation, with a cecal diameter of at least 10 cm, and had had no response to at least 24 hours of conservative treatment. We randomly assigned 11 to receive 2.0 mg of neostigmine intravenously and 10 to receive intravenous saline. A physician who was unaware of the patients' treatment assignments recorded clinical response (defined as prompt evacuation of flatus or stool and a reduction in abdominal distention), abdominal circumference, and measurements of the colon on radiographs. Patients who had no response to the initial injection were eligible to receive open-label neostigmine three hours later. RESULTS: Ten of the 11 patients who received neostigmine had prompt colonic decompression, as compared with none of the 10 patients who received placebo (P<0.001). The median time to response was 4 minutes (range, 3 to 30). Seven patients in the placebo group and the one patient in the neostigmine group without an initial response received open-label neostigmine; all had colonic decompression. Two patients who had an initial response to neostigmine required colonoscopic decompression for recurrence of colonic distention; one eventually underwent subtotal colectomy. Side effects of neostigmine included abdominal pain, excess salivation, and vomiting. Symptomatic bradycardia developed in two patients and was treated with atropine. CONCLUSIONS: In patients with acute colonic pseudo-obstruction who have not had a response to conservative therapy, treatment with neostigmine rapidly decompresses the colon.  (+info)

Review article: the pharmacological treatment of acute colonic pseudo-obstruction. (3/26)

Acute colonic pseudo-obstruction (Ogilvie's syndrome) can be defined as a clinical condition with symptoms, signs and radiological appearance of acute large bowel obstruction unrelated to any mechanical cause. Recent reports of the efficacy of cholinesterase inhibitors in relieving acute colonic pseudo-obstruction have fuelled interest in the pharmacological treatment of this condition. The aim of the present review is to outline current perspectives in the pharmacological treatment of patients with acute colonic pseudo-obstruction. The best documented pharmacological treatment of Ogilvie's syndrome is intravenous neostigmine (2-2.5 mg), which leads to quick decompression in a significant proportion of patients after a single infusion. However, the search for new colokinetic agents for the treatment of lower gut motor disorders has made available a number of drugs that may also be therapeutic options for Ogilvie's syndrome. Among these agents, the potential of 5-hydroxytryptamine-4 receptor agonists and motilin receptor agonists is discussed.  (+info)

Polymyositis as a cause of total gut failure. (4/26)

BACKGROUND: Gastrointestinal manifestations are seen in systemic sclerosis and mixed connective tissue disorders but are rare in pure polymyositis. CASE REPORT: A 44 year old woman with polymyositis who developed total gut failure requiring treatment with total parenteral nutrition is described. RESULTS: The patient's polymyositis is now fully controlled biochemically, but her gastrointestinal symptoms persist.  (+info)

Ogilvie's syndrome treatment. (5/26)

INTRODUCTION: Ogilvie's Syndrome (OS) is a rare condition caused by parasympathetic dysfunction of large bowel characterized by acute and massive colon distension without mechanical obstruction. Rarely this disease has to be treated by the surgeon but operations may be indicated in case of medical treatment failure. METHODS: A retrospective analysis was carried out at the Emergency Surgery DPT of St Orsola-Malpighi University Hospital Bologna Italy. From 1995 to 2002 11 patients were treated for severe OS: they were 8 males and 3 females and the mean age was 68 yrs. All these subjects had large bowel distension with caecum diameter more than 8 cm without any evidence of mechanical obstruction. RESULTS: In 4 patients (36%) OS was caused by trauma or surgical procedures whereas in 7 cases (64%) was produced by other conditions. Only in 3 cases (27%) conservative treatment was successful; the remaining 8 patients were submitted to surgical therapy. 6 patients were submitted to decompressive caecostomy and in 2 cases a subtotal colectomy was done. Mortality was 36%. DISCUSSION AND CONCLUSIONS: Surgical treatment of OS is indicated when there is a conservative treatment failure. The high mortality is related to diagnostic and therapeutic delays, advanced age and comorbidities.  (+info)

Systematic review: acute colonic pseudo-obstruction. (6/26)

Acute colonic pseudo-obstruction is the clinical syndrome of acute large bowel dilatation without mechanical obstruction that is an important cause of morbidity and mortality. Acute colonic pseudo-obstruction occurs in hospitalized or institutionalized patients with serious underlying medical and surgical conditions. The pathogenesis of acute colonic pseudo-obstruction is not completely understood but likely results from an imbalance in the autonomic regulation of colonic motor function. Metabolic or pharmacological factors, as well as spinal or retroperitoneal trauma, may alter the autonomic regulation of colonic function, leading to excessive parasympathetic suppression or sympathetic stimulation. This imbalance results in colonic atony and dilatation. Early recognition and appropriate management are critical to minimizing morbidity and mortality. The mortality rate is estimated at 40% when ischaemia or perforation occurs. The best-studied treatment of acute colonic pseudo-obstruction is intravenous neostigmine, which leads to prompt colon decompression in the majority of patients after a single infusion. In patients failing or having contraindications to neostigmine, colonoscopic decompression is the active intervention of choice. Surgery is reserved for those with peritonitis or perforation.  (+info)

Effect of polyethylene glycol electrolyte balanced solution on patients with acute colonic pseudo obstruction after resolution of colonic dilation: a prospective, randomised, placebo controlled trial. (7/26)

BACKGROUND AND AIMS: Conservative therapy for patients with acute colonic pseudo obstruction (Ogilvie's syndrome) may be successful initially but relapses are common. The aim of the present study was to evaluate the effect of polyethylene glycol (PEG) electrolyte balanced solution on the relapse rate of the syndrome after initial resolution with neostigmine or endoscopic decompression. PATIENTS AND METHODS: The study was performed on 30 consecutive patients who presented with abdominal distension and radiographic evidence of colonic dilation, with a caecal diameter > or = 10 cm, that resolved conservatively. Patients then were randomised to receive daily 29.5 g of PEG (n = 15) or similar placebo (n = 15). Patients were monitored daily for a seven day period for stool and flatus evacuations, and colonic diameter on abdominal radiographs. Administration of the test solutions and assessment of patient symptoms and x rays were performed in a blinded fashion. A caecal diameter > or = 8 cm with a concomitant > or =10% increase after initial successful therapeutic intervention was considered as a relapse and these patients, after a second therapeutic intervention, were eligible to receive open label PEG. RESULTS: Twenty five patients received neostigmine as the initial therapeutic intervention which resulted in resolution of colonic dilation in 88% of cases. Eight patients had successful endoscopic decompression. Five (33.3%) patients in the placebo group had recurrent caecal dilation compared with none in the PEG group (p = 0.04). Therapy with PEG resulted in a significant increase in stool and flatus evacuations (p = 0.001 and 0.032, respectively) as well as in a significant decrease in the diameter of caecum, ascending and transverse colon, and abdominal circumference (p = 0.017, 0.018, 0.014, and 0.008, respectively). CONCLUSIONS: Administration of PEG in patients with Ogilvie's syndrome after initial resolution of colonic dilation may increase the sustained response rate after initial therapeutic intervention.  (+info)

Treatment of pediatric Ogilvie's syndrome with low-dose erythromycin: a case report. (8/26)

Acute colonic pseudo-obstruction is a poorly understood syndrome, characterized by the signs, symptoms and radiological pattern of a large bowel obstruction without evidence for a mechanical obstruction. We report a case of a 2-year old boy who presented with progressive abdominal distention, vomiting and abdominal pain on postoperative d 3. Plain abdominal z-ray showed markedly dilated large bowel. Mechanical colonic obstruction was ruled out with hypaque enema. Ogilvie's syndrome was suspected. The patient received treatment with oral erythromycin which had an immediate beneficial effect. During the 6 mo follow-up, no recurrences of symptoms were observed. We provide a safe and effective therapy for Ogilvie's syndrome in pediatric individuals.  (+info)
