Intestinal obstruction, progressive weight loss, and recurrent fever in two patients with mesenteric lesions.

We describe 2 patients who presented with fever and incomplete intestinal obstruction. Previously, both patients had had laparotomies showing unresectable lesions in the root of the mesentery which were histologically diagnosed as sclerosing mesenteritis in the first and mesenteric fibromatosis in the second patient. In spite of aggressive immunosuppressive therapy the first patient deteriorated with high-grade fever and progressive weight loss. Similar symptoms occurred in the second patient. Computed tomographic scanning revealed necrotic lesions in both patients which histologically were found to be an angiocentric T-cell lymphoma in the first and a superinfected necrotizing fibroma in the second patient. It is therefore clinically and radiologically impossible to distinguish between the different causes of mesenteric lesions. Reoperation for further biopsies needs to be considered if such patients do not respond to medical treatment.

[Intestinal obstruction due to phytobezoar in a Meckel's diverticulum].

Meckel's diverticulum is the most prevalent anomaly of the gastrointestinal tract, found in about 2% of the general population. Most are asymptomatic; but most frequent complications are intestinal obstruction, diverticulitis and lower gastrointestinal bleeding. A 33-year-old man was operated on for mechanical small bowel obstruction caused by a large Meckel's diverticulum filled with a phytobezoar. This mechanism of obstruction is rare. When the history of a patient without previous intestinal operations, as in this case, raises the possibility of phytobezoar, the probability of congenital anomaly is high.

CT in the early detection of strangulation in intestinal obstruction.

The role of CT in evaluating the gastrointestinal tract has increased recently because CT demonstrates pathological conditions involving the bowels, mesenteric vessels, and peritoneal cavity well. In patients who have an intestinal obstruction, the observation of both bowel loop configuration and mesenteric vessels on CT is the key to identifying the site and cause of obstruction and determining the absence or presence of intestinal strangulation. Although many clinical and radiological findings reported in the literature are not seen in the early stages of intestinal strangulation, CT might assist in its early detection. This article reviews the clinical, pathophysiological, and radiological aspects of strangulating obstruction with emphasis on the role of CT in its early diagnosis.

Distal neonatal intestinal obstruction: the choice of contrast material.

The use of barium sulfate as the contrast agent of choice in the radiographic evaluation of distal neonatal intestinal obstruction is advocated. The advantages of Gastrografin or other water-soluble contrast materials are far outweighed by their disadvantages, which include the hazards of hypertonic dehydration and the danger of missing the diagnosis of Hirschsprung's disease. Five patients are presented, all of whom had the diagnosis of Hirschsprung's disease missed in the neonatal period with one use of Gastrografin enemas. All five were subsequently admitted to the Surgical Neonatal Intensive Care Unit, critically ill with enterocolitis of Hirschsprung's disease.

Hypertrophy of mucosa and serosa in the obstructed intestine of rats.

After a surgically induced partial obstruction of the small intestine (ileum) in adult rats there is an accumulation of ingesta and a progressive enlargement of the lumen accompanied by wall thickening: over a period of 2-3 wk the circumference of the hypertrophic intestine increases by a factor of 2.7 and the thickness of the musculature increases more than threefold, while the length of the ileum (measured at the mesenteric attachment) remains unchanged. The villi become markedly larger and more elongated in the circumferential direction, and have a greater separation between one another. The number of villi per unit surface is markedly reduced but the number of villi per unit length of ileum, whilst appearing to show a small increase, was not significantly altered. The component epithelial cells (absorptive cells) appear unchanged in morphology and size (height). The microvilli of the epithelial cells have the same appearance, size (height) and packing density in the control and the hypertrophic ileum. Glands of Lieberkühn, Peyer's patches and single lymphatic follicles constituting the Peyer's patches are significantly increased in size in the hypertrophic intestine. The serosal surface of the hypertrophic ileum, in spite of the great expansion, remains regularly covered by mesothelial cells; these are much larger than in the controls and have an altered distribution of their microvilli.

[Eosinophilic enteritis causing intestinal obstruction].

Eosinophilic enteritis is an uncommon disorder of unknown etiology in which the digestive symptoms are associated with eosinophilic infiltration of the different layers of the intestinal wall. Clinical symptoms depend on the layers involved and are usually characterized by peripheral eosinophilia. Radiological findings depend on the layers involved. Definitive diagnosis is based on clinical and histopathological findings. Treatment of choice is currently with corticoids and prognosis is benign with relapses. The pathogenesis remains unclear. We report a patient who presented with intestinal obstruction and describe the follow-up.

Intestinal obstruction due to mesenteric panniculitis.

This report describes a case of mesenteric panniculitis in a 40-year-old male who presented with features of intestinal obstruction. Computed tomography scan showed a mass in the mesentery of small bowel. Resection of mass with associated small bowel and anastomosis resulted in complete recovery of the patient.

Colic motor complex of the cecum and proximal loop of the ascending colon observed in an experimental cow with large intestinal obstruction.

Myoelectric activity of the cecum and proximal loop of the ascending colon (PLAC) and the effect of xylazine on motility of this intestinal segment in an experimental cow with large intestinal obstruction are described and compared with the normal motility pattern. During obstruction, three major observations were made in the prestenotic area. (i) Mean spike duration, overall duration of spiking activity (expressed as percentage of total recording time), number of spikes propagated from the cecum towards the obstruction site, and velocity of propagated spikes were substantially increased. (ii) The spike frequency was in the physiologic range. (iii) A single injection of xylazine, administered intravenously at a dose of 0.05 mg/kg markedly reduced the mean spike duration, the overall spiking activity, and the number of propagated spike sequences, and abolished signs of abdominal discomfort. Our data indicate that obstruction of the bovine colon causes a similar pattern of prestenotic hypermotility (colic motor complex) as described for the small intestine of the horse. Xylazine may be a suitable drug to disrupt prestenotic hypermotility and alleviate abdominal discomfort during proximal colonic obstruction in cattle.

[Early postoperative intestinal obstructions. Contribution of radiography to diagnosis of the type and to the indication for reoperation (experience in 84 cases)].

The authors report 84 cases of post-operative intestinal obstruction and demonstrate the value of straight XRays and barium meal in the diagnosis of the variety of early post-operative obstruction and the indications for operation. In 74 cases out of 82, a precise diagnosis of the mechanical or paralytic nature of the obstruction was made and the operation always carried out under best possible conditions.
