Gangrene and spontaneous perforation of the cecum as a complication of pseudo-obstruction of the colon: report of three cases and speculation as to etiology.

"Pseudo-obstruction of the colon" refers to a condition in which physical and radiologic findings identical to those associated with mechanical obstruction of the large bowel are found, but in which no organic cause of colonic distention can be identified. These cases may involve progressive proximal large-intestinal dilation to the point of cecal perforation or necrosis. Two cases of spontaneous perforation of the cecum and one case of gangrene of the cecum secondary to proximal distention of the right colon that followed pseudo-obstruction of the colon are presented. Various etiologic factors reported in the medical literature are discussed and analyzed, and an anatomicophysiologic explanation of a possible mechanism, based on sympathetic-parasympathetic neurostimulatory imbalance, is offered.

Small-bowel obstruction secondary to pericecal hernia.

Pericecal hernia is a rare type of internal hernia and, though congenital in origin, may occur at any age, usually with symptoms of acute intestinal obstruction. The pathophysiology and character of these defects are described, and the management of this situation in an 80-year-old patient is reported. Prompt operative intervention to avoid the associated high mortality secondary to strangulation is urged. It is suggested that closure of these defects be performed if incidentally found at laparotomy.

A case of appendiceal mucocele showing massive mucous production with concomitant colonic cancer.

A 58-year-old male patient presented with abnormal discharge of 200 ml transparent fecal mucus. Irregular protuberance of the ascending colon into the adjacent ileocecal region was observed by colonofiberscopy, and a cystic lesion in the ileocecal region was suggested by computerized axial tomography. Pale yellowish semitransparent jellied substances were observed exudating from the site of ileocecal resection. The diagnosis established was moderately differentiated colonic adenocarcinoma and a mucocele of the appendix. The mucus discharge disappeared after resection. Biochemical analysis of the mucus suggested the mucocele as a source of the discharged mucus. We report an extremely rare case of mucocele of the appendix that may be related to the cause of mucous stool.

Generation of reactive oxygen species by Kupffer cells and blood monocytes during intestinal amebiasis in guinea pigs.

The reactive oxygen species generation capacity of Kupffer cells and blood monocytes was studied through chemiluminescence (CL) in guinea pigs, infected intracecally with Entameba histolytica, on days 0, 3, 7, 14 and 21 post infection. There was an elevated response up to the 14th post-infection day. The CL response of these cells was diminished on the 21st post infection day though it was significantly higher than up the controls. The CL response increased exponentially with the severity of cecal lesions. A direct correlation was observed between the CL response of phagocytic cells and cecal lesions of animals. The role of oxygen species in causation of tissue injury during intestinal amebiasis is postulated.

Cecal duplications: a rare cause for secondary intussusception.

Duplications of the alimentary tract are rare congenital anomalies that may occur at any level from mouth to anus. While the oesophagus and the ileum are the most common sites, duplications of the colon are rare. Two cases of ileocolic intussusceptions in 8-month-old girl and 6-month-old boy who were admitted to our hospital with acute abdomen findings are presented. Intraoperatively, cecal cystic duplications leading intussusception were revealed. Intussusception is one of the most important surgical emergence in infancy and typically, it does not involve a lead point in childhood. Although duplication cyst may act as lead point, the review of literature reveals its rarity.

Pseudo-obstruction of the colon during pelvic radiotherapy.

Pseudo-obstruction of the colon, or Ogilvie's syndrome, is characterized by an adynamic, dilated, unobstructed colon, the exact cause of which remains obscure. Although several precipitating factors have been described in the literature, we have observed three patients whose pseudo-obstruction of the colon occurred during interstitial and intracavitary pelvic irradiation. Such a cause has not been noted previously. Pseudo-obstruction of the colon can have serious consequences if it is not recognized early and treated vigorously.

Oxidative parameters and mortality in sepsis induced by cecal ligation and perforation.

OBJECTIVE: This study assessed parameters of free radical damage to biomolecules, mitochondrial superoxide production, superoxide dismutase, and catalase activities and their relationship to sepsis mortality. DESIGN AND SETTING: Prospective animal study in a university laboratory for experimental. SUBJECTS: 140 male Wistar rats. INTERVENTIONS: The animals were randomly divided into three groups: sham-operated (n=20), cecal ligation and perforation resuscitated with normal saline (n=40), and cecal ligation and perforation with normal saline plus antibiotics (n=40). MEASUREMENTS AND RESULTS: Blood samples were collected from all animals 3, 12, and 24 h after CLP through a jugular catheter inserted before CLP. Rats were evaluated during 5 days after the intervention. Nonsurvivor animals were grouped according to the duration between sepsis induction and death, and oxidative parameters were compared to survivors and sham-operated. Lipid peroxidation, protein carbonyls, and superoxide dismutase were significantly increased in nonsurvivor septic rats and were predictive of mortality. We demonstrated that there is a different modulation of superoxide dismutase and catalase in nonsurvivors during the course of septic response. There was a marked increase in superoxide dismutase activity without a proportional increase in catalase activity in nonsurvivors. CONCLUSIONS: This is the first report of plasma superoxide dismutase as an earlier marker of mortality. Ours results might help to clarify an important aspect of oxidative response to sepsis, i.e., an increase in superoxide dismutase activity without a proportional increase in catalase activity

Malrotation with midgut volvulus: CT findings of bowel infarction.

Midgut volvulus, the most common serious complication of malrotation, can be diagnosed using conventional contrast fluoroscopy, US or CT. CT is a quick and comprehensive examination in the evaluation of complex acute abdominal pathology in children. Contrast-enhanced CT can readily help the radiologist recognize perfusion abnormalities of the bowel, which is vital for reducing morbidity and mortality in affected children. Our case emphasizes and demonstrates additional CT features of bowel infarction in a child with a proven malrotation with midgut volvulus.

Cecal volvulus: a rare cause of bowel obstruction in a pediatric patient diagnosed pre-operatively by conventional imaging studies.

Cecal volvulus is an acute surgical condition that is extremely rare in children, with a mortality rate of up to 40%. The clinical symptoms are often non-specific, and pediatric patients frequently have neurological deficits with associated communication difficulties, making the clinical diagnosis extremely challenging. Conventional radiographic imaging studies play a key role in the prospective diagnosis in children. We report a rare case of cecal volvulus in a 12-year-old boy who was diagnosed pre-operatively by abdominal radiographs and a contrast enema.
