Key Words: fecal impaction, fecal incontinence, systemic inflammatory response syndrome.
Constipation and fecal incontinence are common symptoms in patients with neurologic disorders. (1) Gastrointestinal complications of constipation include stercoral ulceration, rectal prolapse, intestinal obstruction, megacolon, and fecal incontinence. (2,3) We present a case of systemic inflammatory response syndrome (SIRS), attributed to fecal impaction.
The patient is a 34-year-old man who presented to the Emergency Department with a 3-day history of severe, diffuse, crampy abdominal pain and anorexia, associated with fever, chills, two episodes of vomiting and oliguria oliguria /ol·i·gu·ria/ (ol?i-gu´re-ah) diminished urine production and excretion in relation to fluid intake.oligu´ric

The patient's personal history was positive for cerebral palsy, mental retardation, and chronic constipation requiring laxatives. He was status post ventriculoperitoneal shunt insertion. He was maintained on phenytoin phenytoin /phen·y·to·in/ (fen´i-toin?) an anticonvulsant used in the control of various kinds of epilepsy and of seizures associated with neurosurgery.

Chest x-ray showed loss of volume of the right lobe, with a clear left lung, deformed chest wall and a dorsal rotoscoliosis. Abdominal films revealed a large fecaloma in the rectum with associated colonic and small bowel dilation (Fig. 1). Plain CT scan of abdomen and pelvis showed significant dilation of the rectum with large fecaloma associated with dilation of the colon, small bowel and stomach (Fig. 2). Digital disimpaction was done followed by water enemas and oral polyethylene glycol solution. The patient was also started empirically on ciprofloxacin and metronidazole. He made an unremarkable recovery. In view of the patient's overall condition and resolution of his symptoms, colonoscopy was not performed.

Typical symptoms of fecal impaction are anorexia, nausea, vomiting and abdominal pain. Paradoxical diarrhea and incontinence may occur. Urinary problems of frequency, retention, and overflow incontinence are also thought to be commonly caused by the mechanical effects of fecal impaction. In fact, the continuous seepage of moist bacteria-laden mucus and stool also fosters the development of decubitus ulceration. Infections of the urinary tract may also be caused by contamination, obstruction, or the direct passage of bacteria from the intestine to the bladder ("enterorenal syndrome"). (6)
Presenting signs may be confusing to the physician. Temperatures as high as 39.5[degrees]C (103[degrees]F), dysrhythmias, and tachypnea caused by the impaired motility of the diaphragm have all been reported with fecal impaction. (7-9) Laboratory abnormalities associated with impactions are nonspecific. Leukocytosis Leukocytosis Definition
Leukocytosis is a condition characterized by an elevated number of white cells in the blood.
Leukocytosis is a condition that affects all types of white blood cells. in which levels reach 15,000 per cubic millimeter may occur. (7) Electrolyte abnormalities, such as hyponatremia Hyponatremia Definition

Hypokalemia is a condition of below normal levels of potassium in the blood serum. Potassium, a necessary electrolyte, facilitates nerve impulse conduction and the contraction of skeletal and smooth muscles, including the heart. , may be associated with impaction. Stool that is positive for blood may reflect the mucosal irritation of an impaction. (7)

When a fecal impaction is suspected but the rectal examination is negative, plain abdominal radiography to look for fecaloma or signs of obstruction, such as colonic dilation and unusual air-fluid levels in the small bowel is indicated.

Our patient developed typical symptoms of fecal impaction, including abdominal pain, anorexia, and nausea. He also developed fecal incontinence, oliguria and prerenal azotemia secondary to decrease fluid intake and gastrointestinal losses. The peculiarity in our case is that the patient had parameters in line with the diagnosis of SIRS. These included:
1. General parameters: fever (>38.3[degrees]C); heart rate > 90 bpm; tachypnea > 30 bpm
2. Inflammatory parameters: leukocytosis (WBC WBC white blood cell; see leukocyte.

The 1992 statement from the American College of Chest Physicians/Society of Critical Care Medicine (ACCP/SCCM) Consensus Conference introduced into common parlance the term "systemic inflammatory response syndrome" (SIRS). The term provides a reference for the complex findings that result from a systemic activation of the innate immune response, regardless of cause. The statement hypothesized that SIRS is triggered by localized or generalized infection, or sterile inflammatory processes. SIRS is considered to be present when patients have more than one of the following: body temperature > 38[degrees]C or < 36[degrees]C; heart rate > 90 bpm/min; hyperventilation hyperventilation /hy·per·ven·ti·la·tion/ (-ven?ti-la´shun)
1. abnormally increased pulmonary ventilation, resulting in reduction of carbon dioxide tension, which, if prolonged, may lead to alkalosis.
2. evidenced by respiratory rate > 20/min or PaC[O.sub.2] < 32 mm Hg; WBC > 12,000 cells/[micro]L or < 4,000/[micro]L. (12) The 2001 Society of Critical Care Medicine/European Society of Intensive Care Medicine/The American College of Chest Physicians/American Thoracic Society/ Surgical Infection Society (SCCM/ESICM/ACCP/ATS/SIS) International Sepsis Definitions Conference (13) concluded that the 1992 consensus definitions are too widely considered to be of utility in diagnosing a cause of the syndrome, since the systemic inflammatory response can be triggered by a variety of infectious and noninfectious causes.
In fact, while the clinical manifestations of systemic inflammation are wide, the biochemical features may be more consistent. Investigators have detected elevated circulating levels of interleukin-6, adrenomedullin, soluble CD14, soluble endothelial cell/leukocyte adhesion molecule-1, macrophage inflammatory protein This article is about proteins. For the chemical compound CCl4, see Carbon tetrachloride.
Macrophage Inflammatory Proteins (MIP) belong to the family of chemotactic cytokines known as chemokines. 1 [alpha], extraphospholipase A2, and C-reactive protein in patients meeting the 1992 SIRS criteria. In the future, if supported by further epidemiologic data, it may be possible to use purely biochemical and/or immunologic inflammatory response markers. It may be that inflammation is present when the circulating concentration of IL-6, procalcitonin, or CRP is increased. No large prospective studies currently support such a conclusion. (14)
Our patient developed SIRS with a negative workup for underlying infectious etiology. To our knowledge, this is the second case of constipation resulting in SIRS. However, in the reported case by Hagen and Jones, (14) group G streptococcal streptococcal /strep·to·coc·cal/ (-kok´al) pertaining to or caused by a streptococcus.
Pertaining to any of the Streptococcus bacteria. bacteremia was identified. Watsky et al (15) suggested a greater role for breaching of the anatomic mucosal or epithelial barriers to infection rather than a specific immune defect in the pathogenesis of this bacteremia. It is possible that our patient could have had a transient group G streptococcal bacteremia or any other bacteremia not detected by blood cultures, with no clinically evident source of infection. Other possible causes of the inflammatory response can be the metabolic alteration associated with bowel obstruction, or the breaching of the anatomic mucosal or epithelial barriers to exotoxins produced by altered flora.
Our patient improved remarkably after digital disimpaction followed by water enemas, along with antibiotics. Reviewing the literature, we did not come across any study that looked at whether digital disimpaction is sufficient to resolve SIRS. This remains an issue to be answered by further workup, looking at the mechanisms of impaction and the effects of digital disimpaction per se.
Our case illustrates the serious sequelae of fecal impaction, which should be considered in patients with neurologic disorders and SIRS. Furthermore, SIRS may be a prelude to full blown sepsis and multiorgan failure.
