Acute colonic pseudo-obstruction post-cesarean section is not a benign entity: A case series and review of the literature

Acute colonic pseudo-obstruction (ACPO) is an infrequent occurrence after cesarean section. Anecdotal evidence suggests that the clinical course of ACPO in the obstetric setting is different to that seen in non-pregnant adult patients with ACPO secondary to alternative causes, such as systemic illnesses, the use of certain medications, and after non-abdominal surgery. The risk of progression to ischemia and perforation, as well as the need for emergency surgery, appears to be higher after cesarean section. Here we describe the clinical course of ACPO in four patients after cesarean section from our institution, followed by a review of the literature and a discussion of the important issues surrounding this condition in the postpartum time period. The findings from our cohort of patients and the reports from the medical literature support a hands-on combined approach from a group of specialists including obstetricians, surgeons, radiologists, and enterostomal therapists. Immediate imaging followed by regular observation is mandatory for any patient being managed conservatively. Early use of endoscopic decompression should be considered for patients who are not resolving with a conservative approach. Clinical signs of peritonism or radiological signs of ischemia or perforation in patients with ACPO mandate immediate surgical intervention. Appropriate postoperative care is necessary to deal with the complex physiological and psychological consequences of emergency surgery and potential stoma formation so soon after cesarean section.

Ogilvie's Syndrome in a Patient at 23 Weeks of Pregnancy: Report of a Rare Case with Successful Surgical Intervention

BACKGROUND Ogilvie's syndrome (acute colonic pseudo-obstruction) is a syndrome characterized by symptoms suggestive of intestinal obstruction without an identifiable mechanical cause. It presents with excessive dilation of the loops of the large intestine. The treatment options include conservative management, endoscopic methods, and surgical intervention. If appropriate treatment is not implemented promptly, this syndrome can lead to life-threatening complications for the patient. Acute colonic pseudo-obstruction typically occurs in elderly individuals with numerous chronic diseases, extensive surgeries, or trauma. In younger individuals, risk factors include gynecological procedures, pregnancy, and childbirth. CASE REPORT This work presents a case of a 30-year-old woman at 23 weeks of pregnancy. She presented with persistent abdominal pain, nausea, and vomiting for several days. The patient was initially treated at the Obstetrics Clinic, where conservative management was implemented. Due to worsening symptoms after confirming pathological distension of the colon in the magnetic resonance imaging examination, she was transferred to the surgery clinic. Due to her unstable general condition and lack of improvement with conservative treatment, she was qualified for an appendectomy with the formation of a cecostomy. The performed surgical treatment led to an improvement in the patient's condition and did not have a negative impact on the further development of the child. CONCLUSIONS Ogilvie's syndrome in pregnancy is an extremely rare condition that can lead to significant complications. Its treatment requires the coordinated efforts of a multidisciplinary team of specialists. During the course of therapy, it is important to consider the limitations imposed by pregnancy on diagnostic and therapeutic methods.

Update on the Diagnosis and Management of Acute Colonic Pseudo-obstruction (ACPO)

PURPOSE OF REVIEW

Acute Colonic Pseudo-obstruction (ACPO) is a cause of large intestinal dilation and obstruction without any physical transition point. It remains difficult to diagnose and treat. We review the recent updates on diagnosis and management of ACPO.

RECENT FINDINGS

Recent guidelines have posited that conservative management can be tried in most cases of ACPO, but that early decompression and surgery should be considered. Use of neostigmine is still a viable option but there is also promising data on pyridostigmine as well as prucalopride. Resolution of ACPO should be followed by daily use of polyethylene glycol (PEG) to help prevent recurrence. ACPO warrants early and accurate diagnosis with exclusion of alternate causes of large bowel dilation. Conservative management can be attempted for 48-72 h in those with cecal diameters < 12 cm and without signs of peritonitis and perforation. Early escalation of management should be attempted with neostigmine followed by endoscopy and/or surgery as needed, given that longer periods of dilation are associated with worse outcomes. There is promising new evidence for use of pyridostigmine and prucalopride, but further trials are needed prior to incorporating them into regular use. Finally, studies are lacking regarding prevention of ACPO after initial resolution.

A case of delayed oxaliplatin-induced pseudo-obstruction: an atypical presentation of oxaliplatin neurotoxicity

Chemotherapy-induced neurotoxicity is a serious complication of cancer treatment. Oxaliplatin, a third-generation platinum drug, has become one of the first-line therapies used in the treatment of metastatic colorectal cancer. Peripheral neuropathy is a common complication of platinum-based chemotherapy. Most commonly a sensory neuropathy occurs with cold-triggered symptoms in the acute phase and numbness and painful paresthesias as a late presentation. Autonomic neurotoxicity and late presentation, months after cessation of the therapy, has rarely been described. We report a patient who clinically presented with a pseudo-obstruction months after treatment with oxaliplatin for metastatic colorectal cancer. Intestinal adhesions and relapsing malignancy were carefully excluded. By exclusion the pseudo-obstruction was attributed to a toxic oxaliplatin-induced autonomic neuropathy which slowly improved during months of follow-up.

[Treatment of acute colonic pseudo-obstruction (Ogilvie's Syndrome). Systematic review]

BACKGROUND

Ogilvie's syndrome is acute colonic dilatation without organic obstacle in a previously healthy colon. Surgery is the only treatment of cases complicated by necrosis or perforation. In contrast, treatment of uncomplicated forms is not unanimous, and is the subject of this literature review.

AIMS

Determine the results of different therapeutic methods of uncomplicated forms of Ogilvie's syndrome in terms of efficiency of removal of colonic distension, recurrence, morbidity and mortality. Clarify their respective indications.

METHODS

An electronic literature search in the "MEDLINE" database, supplemented by hand searching on the reference lists of articles, was conducted for the period between 1980 and 2012.

RESULTS

Conservative treatment is effective in 53 to 96% of cases with a risk of colonic perforation less than 2.5% and a mortality of 0 to 14% % (level of evidence 4, recommendation grade C). Neostigmine is effective in 64 to 91% of cases after a first dose, with a risk of recurrence of 0 to 38%. It remains effective in 40 to 100% of cases after a second dose (evidence level 2, grade recommendation B). Endoscopic decompression is a safe and effective technique with a success rate of 61 to 100% at the first attempt , a recurrence rate of 0 to 50%, a rate of colonic perforation less than 5% and a mortality less than 5% (level evidence 4, recommendation grade C). PEG may be recommended for the prevention of recurrence of the ACPO after successful treatment with neostigmine or endoscopic decompression (evidence level 2, recommendation grade B). The cecostomy is more effective and safer than conventional colostomy (level of evidence 4, recommendation grade C). The cecostomy is highly effective in colonic decompression but associated with a high mortality (level of evidence 4, recommendation grade C).

CONCLUSION

Conservative treatment is recommended in first intention. In case of failure, neostigmine should be tried. If unsuccessful, the endoscopic decompression is proposed. The cecostomy is indicated as a last resort after failure of endoscopic decompression.

[Diagnosis and treatment of acute colonic pseudo-obstruction]

Acute colonic pseudo-obstruction (ACPO), also known as Ogilvie's syndrome, is a clinical condition with acute dilatation of the colon without a provable mechanical cause. Early recognition and treatment of the condition is important in order to improve the outcome. The diagnosis is based on clinical and radiographic findings. Supportive therapy should be the initial management. If no improvement occurs after 24 hours, medical treatment with neostigmine administered i.v. is instituted and repeated if necessary. Colonoscopic decompression is the next step, but if ischaemia or perforation appear surgery should be performed.

[Successful conservative treatment of coecal perforation in a patient with Ogilvie's syndrome]

The case report describes a 37-year-old woman who was diagnosed with Ogilvie's syndrome after caesarean section. Conservative treatment was initiated with minimal effect, and the patient was subsequently treated with IV neostigmine. A computed tomography of the abdomen revealed enlarged peritoneal cavity. However the patient was clinically unaffected without fever or signs of peritonitis. The perforation was managed with a conservative approach including antibiotics and close observation of the patient. After nine days the patient was discharged with normal gastrointestinal function and without further reported complications.

[Case-control study on acute colonic pseudo-obstruction after total hip or knee arthroplasty]

OBJECTIVE

To investigate the incidence, predisposing factors and therapeutic modalities of acute colonic pseudo-obstruction (ACPO) in patients after total hip arthroplasties (THA) and total knee arthroplasties (TKA).

METHODS

From January 2006 to December 2009, 12 patients with ACPO after THA and TKA operation were investigated retrospectively,who were viewed as the ACPO group. There were 10 males and 2 females with an average age of (78 +/- 12) years in the ACPO group. Other 853 patients without ACPO after THA and TKA operation were viewed as the control group treated at the same period. The incidence of ACPO was calculated. The clinical data were collected and compared between the two groups including patient age, gender, procedure, anesthetic class, clinical presentation, radiographic findings, duration from index surgery to diagnosis of ACPO, treatment, postoperative mobilization time, and length of hospital stay.

RESULTS

The incidence of ACPO was 1.4%. The incidence of primary THA (1.3%) was higher than that of primary TKA (0.4%); the incidence of hip and knee revisions (5.0%) was higher than that of primary THA and TKA (1.0%); there was no difference in incidence between hip revisions (5.5%) and knee revisions (4.0%). The mean age was (78 +/- 12) years old in ACPO group and (71 +/- 13) in the control group. The male/female ratio was 5:1 in ACPO group and 2:3 in control group. There were statistical differences in mean age and gender ratio between the two groups. No association was found with respect to anesthetic class. On average, ACPO occurred at 2.5 days after index surgery. The abdominal distention occurred in all 12 cases, nausea or vomiting in 8 cases and abdominal pain in 3 cases. Radiographically cecal dilation occurred in all cases and intestinal dilation in 3 cases. All patients initially were treated conservatively with immediate cessation of oral intake,a nasogastric tube and oral mineral oil. Three patients received a rectal tube. Only 1 patient required endoscopic decompression. There were no deaths after ACPO in the series. Mean mobilization time after surgery averaged (5.0 +/- 2.2) days in ACPO group compared with (2.5 +/- 1.1) days in the control group. Mean hospital stay averaged (16.5 +/- 6.4) days in ACPO group compared with (10.5 +/- 4.5) days in the control group. There were statistical differences in mean mobilization time after surgery and mean hospital stay between two groups.

CONCLUSION

ACPO mainly happened in old male patients. The majority cases response to conservative treatment and their prognoses are good. But ACPO will delay mobilization time after surgery and increase hospital stay.

[Ogilvie's syndrome after cesarean section: A case report]

Ogilvie's syndrome is a rare postsurgical complication. The high mortality rate (normally 15 to 31% and up to 45% after caecal perforation) explains the seriousness of this clinical situation. The early diagnosis is made by plain abdominal X-ray. Conservative treatment is usually effective and surgery should be reserved for complicated cases or refractory to conservative treatment. We report a case of Ogilvie's syndrome after cesarean section, which has been treated by conservative methods.

Safety and efficacy of colonoscopy during pregnancy: an analysis of pregnancy outcome in 20 patients

OBJECTIVE

To analyze maternal and fetal safety of colonoscopy during pregnancy.

STUDY DESIGN

Retrospective study comparing fetal outcomes at 2 hospitals from 1986 to 2007 of 20 pregnant women undergoing colonoscopy vs. 20 matched pregnant controls not undergoing colonoscopy.

RESULTS

Colonoscopic indications included diarrhea (8), hematochezia (4), bloody diarrhea (3), abdominal pain (2) and other (3). Colonoscopy was performed during the first trimester in 2, second trimester in 16 and third trimester in 2. Colonoscopic intubation was to cecum (11), hepatic flexure (2) and transverse colon (7). Excluding 1 successful therapeutic colonoscopy, colonoscopy was diagnostic in 10 of 19 cases, including ulcerative colitis (5), ischemic colitis (2), Crohn's colitis (2) and lymphocytic colitis (1). Colonoscopy led to therapeutic changes in 7 (35%). Two minor maternal procedural complications occurred (mild, transient hypotension). No fetal distress was detected during colonoscopy by fetal heart rate monitoring in 6 patients. Study patients had 1 involuntary abortion and 1 infant born with congenital defects; all other infants were born relatively healthy. Study patients had similar or lower rates than controls of these unfavorable fetal outcomes: involuntary abortion, premature delivery, low birth weight, congenital defects, neonatal ICU stay, infant postpartum hospitalization > or = 4 days and infant death after live birth. Study infants had similar or higher mean Apgar scores vs. controls at 1 and 5 minutes.

CONCLUSION

Pregnant patients undergoing colonoscopy tended to have better, but not statistically significant, fetal outcomes than matched pregnant controls not undergoing colonoscopy. Colonoscopy may be relatively safe, without large fetal risks, during the second trimester and may improve fetal outcome. Colonoscopy may be performed when strongly indicated during the second trimester.

Gastrointestinal motility in acute illness

Critical illness affects gastrointestinal motility - not only as a primary problem, which brings the patient to the intensive care unit (ICU), but also as a complication consecutive to the ICU stay. Motility disturbances may result from impaired function of gastrointestinal muscle, pacemaker cell function and nerve activity. The most important neural control system is the enteric nervous system that contains the largest collection of neurons (10(8) cells) outside the central nervous system. Through its organization it can operate independently of the brain and generate motility patterns according to need: a postprandial motility pattern starting after food intake, and an interdigestive motility pattern starting several hours after a meal. Undisturbed intestinal motility depends critically on a balanced interaction between inhibition and excitation, and a disturbance in this balance leads to severe derangements of intestinal motility. These motility disturbances differ in clinical appearance and location but can affect all parts of the gastrointestinal tract. This review focuses on select motility disturbances such as gastroparesis, postoperative ileus, and Ogilvie's syndrome. Generally effective methods to treat these conditions are given. Finally, we focus on special management options to prevent such motility disturbances or to reduce their severity.

Use of three lumen catheter facilitates bowel movement after pancreato-duodenectomy

BACKGROUND/AIMS

The advantages of jejunal nutrition in postoperative bowel paralysis following pancreato-duodenectomy were analyzed.

METHODOLOGY

Patients resected for pancreatic cancer received 25 kcal/kg/day and were followed up for 10 days postoperatively. Nasojejunal tube ensured enteral feeding in 16 patients (Gr. I), 6 patients (Gr. II) were nourished parenterally. Laboratory parameters, outcome were compared. Bowel movements were registered. Patients of Gr.1 received 25 kcal/kg parenterally. Jejunal nutriment (1.5 cal/mL) followed gradually up to 1500mL. Parenteral nutriment decreased reflecting enteral intake. Patients of Gr. II were nourished parenterally only for 8 days. Laboratory data were measured preoperatively, on the 1st, 4th, 10th days.

RESULTS

The first stool appeared on the 4th day in Gr. I In Gr. II the bowel movement was delayed by 8 days. Laboratory data from the 1st, and 10th days were compared. In Gr. I serum total protein increased from 48.06 to 58.7g/L (p<0.001), serum albumin from 27.5 to 32.2g/L (p<0.02), CRP decreased from 117.8 to 74.1mg/L (p<0.035). No changes were significant in Gr. II. Length of hospitalization, weight loss did not differ between the 2 groups.

CONCLUSIONS

Immediately postoperative use of a three-luminal tube ensured early enteral nutrition, improved serum total protein, albumin values and facilitated bowel movements.

Acute colonic pseudo-obstruction

Acute colonic pseudo-obstruction (ACPO) is a syndrome of massive dilation of the colon without mechanical obstruction that develops in hospitalised patients with serious underlying medical and surgical conditions. ACPO is associated with significant morbidity and mortality, and, therefore, requires urgent gastroenterologic evaluation. Appropriate evaluation of the markedly distended colon involves excluding mechanical obstruction and other causes of toxic megacolon such as Clostridium difficile infection, and assessing for signs of ischemia and perforation. Increasing age, cecal diameter, delay in decompression, and status of the bowel significantly influence mortality, which is approximately 40% when ischemia or perforation is present. The risk of colonic perforation in ACPO increases when cecal diameter exceeds 12cm and when the distention has been present for greater than 6days. Appropriate management includes supportive therapy and selective use of neostigmine and colonoscopy for decompression. Early recognition and management are critical in minimising complications.

Pseudoobstruktion

Die intestinale Pseudoobstruktion ist eine seltene Motilitätsstörung des Gastrointestinaltrakts, mit Symptomen eines akuten oder chronischen Darmverschlusses, ohne mechanisches Korrelat. Bei der akuten Pseudoobstruktion des Kolon (Ogilvie Syndrom) wird eine Imbalance des autonomen Nervensystems vermutet. Die chronisch intestinale Pseudoobstruktion kann angeboren oder erworben sein, und verschiedene Ursachen, unter anderem eine viszerale Neuro- oder Myopathie, sind beschrieben. Die Patienten leiden unter Bauchschmerzen, Erbrechen, Obstipation oder Diarrhö. Diagnostisch sollten eine mechanische Obstruktion, eine Ischämie oder eine Perforation ausgeschlossen werden. Die akute Pseudoobstruktion wird in Abhängigkeit des Ausmaßes und Dauer der Kolondilatation supportiv, medikamentös oder interventionell behandelt. Die Behandlung der chronischen Pseudoobstruktion ist abhängig vom Schweregrad der Erkrankung und erfolgt in aller Regel interdisziplinär.

[Acute colonic pseudoobstruction: Ogilvie's syndrome]

Based on literature and own original clinical data authors conclude that Ogilvie's syndrome is the form of dynamic obstruction of colon due to lesion of retroperitoneal neural nodes, heart failure and intoxication. Ogilvie's syndrome complicates therapeutic and surgical diseases. This syndrome can be manifested with acute abdomen symptoms and at 22% cases may be the cause of surgical treatment. Ogilvie's syndrome is successfully treated with evacuation of intestinal contents, but the risk of recurrence after this treatment is high. Ethiotropic therapy, correction of water-electrolytic balance and tissues oxygenation, administration of acetylcholinesterase inhibitors are the more effective treatment of this syndrome.

[The acute pseudobstruction of the colon, or Ogilvie's syndrome: a rare cause of acute abdomen, high mortality and associated pathologies in an internal medicine department]

The acute pseudobstruction of the colon or Ogilvie's syndrome is a infrequent pathology of acute or subacute evolution, that is associated to different clinical or surgical pathologies, and whose pathophysiology continues to be unknown. The treatment begins with general measures and if these are not effective, with the surgical decompression of colon to avoid the most serious complication, and frequently that is perforation of the cecum. We present a case of an acute and idiopathic dilatation of colon in an adult man who entered by an episode of acute respiratory insufficiency, and that was solved with preservative medical treatment.

Akute intestinale Kolonpseudoobstruktion 2 Tage nach Versorgung einer pertrochantären Femurfraktur

Acute colonic pseudoobstruction, following traumatic injuries, is a rare diagnosis. Nevertheless it is life threatening, if it is not recognized and treated promptly. We report one case of this so-called Ogilvie's syndrome, which followed fixation of a trochanteric fracture by intramedullary nailing within 2 days. Due to massive acute colonic distension, the patient suffered from respiratory failure. We excluded other intestinal diseases by CT scanning. After conservative colonic decompression, he recovered after 2 days in the intensive care unit. We describe a variable treatment depending on the severity of the colonic atony. Knowledge of Ogilvie's syndrome, or acute colonic pseudoobstruction, is a must for trauma surgeons, since it can occur within a few hours and can lead to dramatic situations.

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

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.

Acute colorectal obstruction treated by means of transanal drainage tube: effectiveness before surgery and stenting

OBJECTIVES

The aim of this study was to clarify the usefulness of the management of acute colorectal obstruction using a transanal drainage tube before surgery or stenting.

METHODS

Fifty-four patients (34 males and 20 females, aged 46-94 yr, mean = 69.7) treated between May 1998 and March 2004 for acute colorectal obstruction were identified in a colorectal obstruction database, and their clinical and radiological features were reviewed. Based on abdominal computed tomography findings, urgent colonoscopy was performed. Subsequently, endoscopic decompression using a Dennis Colorectal Tube (DCT) was attempted.

RESULTS

Endoscopic decompression using the DCT was technically successful in 52 of 54 patients (96.3%). The site of obstruction was the cecum in 4, the ascending colon in 2, the transverse colon in 7, the descending colon in 11, the sigmoid colon in 18, and the rectum in 12. The etiology of obstruction was primary colorectal carcinoma in 45, non-colonic metastatic carcinoma in 4, postoperative obstruction in 4, and retrograde intussusception in 1. Following adequate cleansing of the colon, 44 patients underwent a one-stage surgery after 7+/- 3 days (SD; range, 4-10 days). Stenting was successfully used as the final palliative treatment in 4. The use of the DCT alone relieved postoperative stenosis (3 patients) and retrograde intussusception (Prognosis in patients with obstructing colorectal carcinoma. Am J Surg 1982;143:742-7). During these treatments, perforation occurred in one patient with postoperative stenosis of the cecum.

CONCLUSIONS

Management of acute colorectal obstruction using the DCT was found to be effective and safe, irrespective of the site or etiology of the obstruction. Therefore, this procedure should be considered as a primary method for decompression of the obstructed colon before considering surgery or stenting.

Systematic review: acute colonic pseudo-obstruction

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.

Spinal anesthesia and Ogilvie's syndrome

Ogilvie's syndrome is an uncommon disorder of acute colonic pseudoobstruction that is often associated with concomitant medical disease or psychiatric medication. Therapeutic interventions include cholinesterase inhibitors, colonic decompression, and, in severe cases, surgery. We report a case of functional obstruction that was resolved after spinal anesthesia. The effect of spinal anesthesia on the autonomic control of colonic motility is discussed, and the literature on neuraxial blockade and Ogilvie's syndrome is reviewed.

Ogilvie's syndrome (acute colonic pseudo-obstruction): review of the literature and report of 6 additional cases

PURPOSE

Ogilvie's syndrome is defined as an acute pseudo-obstruction of the colon, characterized by the signs, symptoms and radiological pattern of a large-bowel obstruction, but without a detectable organic cause. The aetiology of Ogilvie's syndrome appears to be multifactorial, with a series of possibly interacting pathogenic noxae all resulting in colon inactivity. Our study reports on six cases of Ogilvie's syndrome diagnosed and treated between 1997 and 2002.

MATERIALS AND METHODS

From October 1997 to September 2002 we studied six patients affected by pseudo-obstruction of the colon. The pseudo-obstruction was recurrent in two cases. Acute dilatation of the colon without radiologically-detectable organic obstruction was the inclusion criterion for the study.

RESULTS

Plain abdominal radiography revealed colon dilatation that extended to the splenic flexure in three patients, to the hepatic flexure in two patients, and confined to the transverse colon in one patient. None of the patients showed air-fluid levels of the small intestine.

CONCLUSIONS

The most relevant clinical finding in Ogilvie's syndrome is abdominal distension, which arises suddenly, has a progressive course and reaches massive levels. The first-line diagnostic investigation is plain abdominal radiography which shows extreme colon dilation without air-fluid levels of the small intestine. In three of our patients, conservative therapy alone was able to restore normal conditions within five days; two patients required decompressive colonoscopy, and one patient died from cardio-circulatory arrest after 48 hours.

Acute large bowel pseudo-obstruction due to multiple myeloma

Involvement of the gastrointestinal (GI) tract by multiple myeloma (MM) is extremely rare. The small intestine and stomach are the most frequent sites of spread. We report 1 case of a 61-year-old woman who presented with clinical and radiographic features of an acute large bowel pseudo-obstruction. An abdominal computerized tomography (CT) showed a large tumor of the rectum. On morphological and immunohistochemical examination the tumor fulfilled the criteria of MM. The patient received combined chemotherapy and radiotherapy which led to the disappearance of the tumor. A review of the literature revealed that this is the first reported case of MM presented as acute large bowel pseudo-obstruction due to a rectal myeloma tumor.

Acute colonic pseudoobstruction

Acute colonic pseudoobstruction (ACPO) is a clinical condition of acute large bowel obstruction without mechanical blockage. ACPO occurs most often in hospitalized patients with serious underlying medical and surgical conditions. ACPO is an important cause of morbidity and mortality. The pathogenesis of ACPO is not completely understood but likely results from an imbalance in the autonomic regulation of colonic motor function. Metabolic or pharmacologic 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 pseudoobstruction. Early recognition and appropriate management are critical to minimizing morbidity and mortality. The mortality rate is estimated at 40% when ischemia or perforation occurs. The best documented treatment of ACPO is intravenous neostigmine, which leads to prompt 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 overt peritonitis or perforation.

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.

New solutions to an old problem: acute colonic pseudo-obstruction

Acute colonic pseudo-obstruction remains a serious medical disorder, carrying a mortality rate of 15%. It occurs in the setting of a wide variety of medical and surgical illnesses. The suspected pathogenesis consists of an autonomic imbalance resulting from decreased parasympathetic tone or excessive sympathetic output. Patients typically present with abdominal distension, pain, and altered bowel movements. Progression of disease can lead to colonic ischemia and perforation. The diagnostic evaluation excludes mechanical obstruction, toxic megacolon, perforation, and ischemia. Initial treatment most often consists of conservative measures that are followed by intravenous neostigmine when the patient fails to improve. When colonic distension persists, decompression colonoscopy is preformed. Occasionally, these measures fail necessitating surgical intervention.

Ogilvie's syndrome

Four cases of Ogilvie's syndrome (acute colonic pseudo-obstruction) are reported. All occurred in the early puerperium following cesarean section and cesarean hysterectomy. In three of the patients, the diameter of the distended cecum was less than 9.0 cm and so management was conservative while in the fourth patient it was more than 9.0 cm, and so surgical intervention was carried out. A cecal diameter of 9.0 cm or above is an indication for surgical intervention to prevent possible colonic perforation. Other indications for surgery include established cecal perforation and failed conservative management. It is important that an early diagnosis is made and management instituted in order to prevent complications and associated high mortality.

[Ogilvie syndrome in the elderly: retrospective study of 40 cases]

OBJECTIVE

To assess, in a population of elderly patients, the circumstances clinical and progressive characteristics and form of management of an acute colonic pseudo-obstruction (ACPO).

METHOD

Retrospective study of the files of 40 patients aged 70 and more having presented an acute colonic pseudo-obstruction and hospitalised in the university hospital in Dijon from January 1995 to June 2000.

RESULTS

The population was composed of 24 men (60%) and 16 women (40%) with a mean age of 80.8 years. The reasons for hospitalisation were varied: only 15 patients had been referred for an occlusive syndrome. 39 patients presented with abdominal distension, 30 suffered from abdominal pain. In this population, 17 patients exhibited reduced or clearly limited mobility, 20 patients had altered cognitive capacity with an MMS < 20. Thirty-eight patients suffered from a progressive heart disease and 8 patients presented with advanced dementia. The usual treatment of these patients to help the intestinal transit included diuretics in 25 cases and agents slowing the transit in 19 cases. Biologically speaking, hypokalaemia was observed in 21 cases and increased thyroid stimulating hormone (TSH) in 3 cases. An image was obtained of the abdomen without preparation in all patients: the mean caecum diameter was of 9.8 cm. A colon aspiration was performed in 20 patients and molecules to improve peristaltism were administered in 21 cases, with neostigmine prescribed for 9 patients. Surgery was required for 7 patients and 3 of them subsequently died. In terms of progression, 20 patients were cured after treatment, 13 relapsed and 7 patients worsened. Unfortunately, 10 patients died in our series.

DISCUSSION

In our study, the clinical profiles of acute colonic pseudo-obstruction were similar to those described in the literature: they occurred in varying circumstances, in medical or surgical settings ina predominantly male population of elderly, heavily dependent,patients. Treatment of this affection is not clearly codified for fragile patients with multiple diseases and the mortality rate observed should stimulate further studies, notably on pharmacological level.

Intestinal obstruction and perforation--the role of the surgeon

Intestinal obstruction and perforation are always a challenge for the surgeon, not only in respect to the surgical option offered to the patient, but also to the ability to accurately diagnose and stage the disease. The understanding of the underlying pathophysiological mechanism is also very important in order to classify each patient in order to receive the more appropriate treatment. Mechanisms of obstruction and perforation, methods of diagnosis as well as prevention and treatment of the disease were reviewed.

Ogilvie's syndrome--acute colonic pseudo-obstruction. Case report and review of the literature

We present a rare entity of colonic pseudo-obstruction, characterised by severe colonic dilatation in absence of any organic obstacle. Clinical symptoms, diagnostic approach, and therapeutic measures are analysed and discussed. Many factors have been associated with this syndrome which include electrolyte imbalance, systemic infection, drugs, and occasionally, neurologic disease. Reported here is a case of acute colonic pseudo-obstruction which developed in a patient with restrictive respiratory dysfunction. Colonic decompression by means of colonoscopy, the most effective therapeutic approach for pseudo - obstruction failed, and surgical cecostomy was required. The acute colonic pseudo-obstruction, Ogilvie's Syndrome, most often appears as a complication of other clinical conditions. It is characterized by massive colonic dilatation in the absence of a mechanical cause and may lead to cecal perforation in absence of treatment. When colonic obstruction is suspected, one should always consider the possibility of the occurrence of Ogilvie's syndrome

[Ogilvie's syndrome: a rare cause of the acute abdomen]

Ogilvie's syndrome (acute colonic pseudo-obstruction) is a rare clinical disease characterized by segmental distension of the proximal colon caused by a paralysis without mechanic obstruction. It may be a sequel of underlying neurological, medical or surgical disease. Risk factors are respiratory decompensation, electrolyte disturbances and different drugs. A special kind is the primary idiopathic pseudoobstruction with a high risk of perforation or necrosis. Especially elderly patients (> 70 years) with cardiovascular or neurologic diseases and accordant drugs are concerned. Clinical symptoms are progressive abdominal distension and abdominal pain like an acute abdomen. The differential diagnosis of a mechanic ileus is important for further treatment. This case report should draw attention to this rare disease.

Colonic pseudo-obstruction: the dilated colon in the ICU

Acute colonic pseudo-obstruction is a syndrome of massive dilation of the colon without mechanical obstruction that develops in hospitalized patients with serious underlying medical and surgical conditions. Increasing age, cecal diameter, delay in decompression, and status of the bowel significantly influence mortality, which is approximately 40% when ischemia or perforation is present. Evaluation of the markedly distended colon in the intensive care unit setting involves excluding mechanical obstruction and other causes of toxic megacolon such as Clostridium difficile infection, and assessing for signs of ischemia and perforation. The risk of colonic perforation in acute colonic pseudo-obstruction increases when cecal diameter exceeds 12 cm and when the distention has been present for greater than 6 days. Appropriate management includes supportive therapy and selective use of neostigmine and colonoscopy for decompression. Early recognition and management are critical in minimizing complications.

Ogilvie's syndrome treatment

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.
