About one case of necrotising enterocolitis following an extra-peritoneal and aseptic operation, it seems that a post-operative ileus, by the ischemia of mucous membrane and the swarming of anerobics that it involves, seems to be responsable of this dreadful complication. The macroscopic and deceiver aspect of intestine to an early re-operation can impeed this diagnosis. The hyperbaric oxygenotherapy seems to be a perceptible adjuvant treatment.

We describe our observations on abdominal roentgenograms without preparation in two cases of segmental colon infarct and eighteen cases of ischemic colitis. In both infarct cases a colic ileus was noted. In one patient the infarcted loop appeared as gas contrasted. In the ischemic cases there were, in addition to the bowel ileus: a colectasis in two patients, a collapsed segment in thirteen and a gas-filled segment in three. When associated to a significant clinical situation the two latter images have some diagnostic value. In the majority of patients, the contrast enema made possible a diagnosis of ischemic colitis; in three it shaved the sigmoid narrowing responsible for the ischemia.

Plain film of the abdomen is widely used in the diagnostic evaluation of intestinal occlusion. Even though this technique can yield a panoramic and high-resolution view of gas-filled intestinal loops, several factors, such as type and duration of occlusion, neurovascular status of the intestine and general patient condition, may reduce the diagnostic specificity of the plain film relative to the organic or functional nature of the occlusion. From 1987 to 1989, fifty-four patients with intestinal occlusion were studied combining plain abdominal film with abdominal ultrasound (US). This was done in order to evaluate whether the additional information obtained from US could be of value in better determining the nature of the ileus. US evaluation was guided by the information already obtained from plain film which better demonstrates gas-filled loops. The results show that in all 27 cases of dynamic ileus (intestinal ischemia, acute appendicitis, acute cholecystitis, acute pancreatitis or blunt abdominal trauma) US demonstrates: intestinal loops slightly increased in caliber, with liquid content, or loops containing rare hyperechoic particles, intestinal wall thickening and no peristalsis. In 27 cases of acute, chronic or complicated mechanical ileus (adhesions, internal hernia, intestinal neoplasm, peritoneal seedings) US shows: 1) in acute occlusion: hyperperistaltic intestinal loops containing inhomogeneous liquid; 2) in chronic occlusion: liquid content with a solid echogenic component; 3) in complicated occlusion: liquid stasis, frequent increase in wall thickness, moderate peritoneal effusion and inefficient peristalsis. In conclusion, based on the obtained data, the authors feel that the combination of plain abdominal film and abdominal US can be useful in the work-up of patient with intestinal occlusion. The information provided by US allows a better definition of the nature of the ileus.

Our patient with peritonitis, chronical ileus and ileostoma has had the atherosclerotic occlusive changes in aorto-iliac area on both sides. Hypotensive crises must have made hemodynamic conditions worse, permitting thrombosis in the collateral circulation to cause acute ischemia of the right leg. Because of the bad general condition and infection on the anterior abdomen wall, the axillo-femoral bypass has been the only way for the arterial reconstruction and salvation of the leg.

A previous article (Part I) described the patient population and operative management of 666 patients who had surgery for nonruptured abdominal aortic aneurysms. This article details the perioperative complications and, by chi-square and logistic regression analysis, identifies the variables that are associated with each complication. In summarizing the results (below) the incidence of each complication is listed, along with the predictive risk factors in parentheses that have significance levels less than 0.05. Vascular morbidity data are as follows: intraoperative bleeding, 4.8%; postoperative bleeding requiring transfusion, 2.3% or repeat operation, 1.4% (large volume of blood transfusion and/or use of an autotransfusion device); intraoperative limb ischemia, 3.5%; graft thrombosis, 0.9% (femoropopliteal disease and/or distal anastomosis at the femoral level); distal thromboembolism, 3.3% (male sex, femoral popliteal disease, and/or intraoperative graft thrombosis); amputation, 1.2%; graft infection, 1 case. General morbidity data are as follows: cerebrovascular event, 0.6%; paraplegia, 1 case; cardiac event, 15.1% (age, previous episode of congestive heart failure, and/or electrocardiogram [ECG] evidence of a previous myocardial infarction); myocardial infarction, 5.2% (advancing age, angina, and/or prolonged aortic cross-clamp time); congestive heart failure, 8.9% (previous history of congestive heart failure, ECG evidence of ischemia, and/or chronic obstructive lung disease); arrhythmia requiring treatment, 10.5% (preoperative ventricular premature beats and/or respiratory failure requiring ventilation for more than 48 hours); new arrhythmia, 8.4% (angina and/or chronic obstructive lung disease); respiratory failure, 8.4% (chronic obstructive lung disease, large volume of blood transfused, and/or occurrence of postoperative bleeding, cerebrovascular accident, congestive heart failure, or myocardial infarction); renal damage with rise in creatinine or blood urea nitrogen, 5.4% and/or renal failure requiring dialysis, 0.6% (elevated preoperative creatinine, suprarenal aortic cross-clamping, and/or renal vein ligation); diarrhea without evidence of ischemia colitis, 7.1% and ischemic colitis, 0.6% (pelvic flow interrupted); prolonged ileus, 11.0% (aortoiliac occlusive disease, deterioration of renal function, prolonged ventilation, and/or preoperative history of angina); superficial wound infection, 1.5% and deep infection, 0.5% (femoral anastomosis and/or female sex); coagulopathy, 1.1% (large volume of blood transfused).(ABSTRACT TRUNCATED AT 400 WORDS)

A variety of drugs and toxins can produce severe abdominal pain and, in some cases, a surgical abdomen. Toxins can be classified according to mechanisms of injury: 1. Corrosives often produce severe gastroenteritis and may result in gastric or esophageal perforations. Examples of corrosive substances include aspirin, iron, mercury, acids and alkali. 2. Drugs may cause intestinal ileus or obstruction by pharmacologic actions (i.e., anticholinergic drugs and narcotics) or by mechanical obstruction (charcoal and drug bezoars). 3. Abdominal pain simulating an acute abdomen may result from systemic effects of black widow spider envenomation or intoxication with heavy metals such as lead and arsenic. 4. Ischemic bowel disease may occur from use of vasoconstrictor drugs, such as ergotamines, amphetamines and cocaine, or may follow treatment with catecholamines or digitalis in critically ill patients. Small bowel ischemia is life-threatening and may require bowel resection. 5. Many drugs cause abdominal pain by directly injuring abdominal organs, such as the liver and pancreas. Antibiotic-associated colitis may present with abdominal pain and inflammatory diarrhea. Consideration of drugs and toxins plays an important role in the differential diagnosis of the acute abdomen.

Primary tissue closure of gastroschisis remains controversial. Some surgeons routinely place a silicone rubber sheet silo over the exposed bowel, planning a staged closure. In the past 14 1/2 years, we have cared for 106 newborns with gastroschisis, closing the defect primarily in 80%. The success of this technique depends on enlarging the abdominal cavity and decreasing the volume of bowel that must be replaced in the peritoneal cavity. Thorough preoperative rectal irrigation should evacuate all meconium. After undermining the skin around the abdominal wall defect for only 1 cm, a midline subcutaneous fasciotomy is created from the xiphoid to the pubis. The abdominal wall is then stretched in all quadrants beginning at the flanks. The eviscerated small bowel can often be returned without enlarging the initial skin defect. The skin is closed with subcuticular absorbable sutures reinforced by long skin tapes. The small ventral hernia that results is closed at about 1 year of age. Fascia could be closed primarily in 28% of these patients, and 17% required a prosthetic pouch. The duration of postoperative ileus and length of hospital stay were statistically significantly shorter in the infants who underwent primary closure. Even though more complicated patients were included in the primary closure group, the incidence of mortality and morbidity was not higher than in patients treated with silicone rubber pouches. Deaths were inevitable in five infants with gangrenous bowel, multiple anomalies, and extreme prematurity. Deaths were related to sepsis in three infants and were the result of operative or anesthetic technique in four. Only two preoperative factors were prognostic of morbidity and mortality: gestational age (but not birth weight) and the presence of intestinal ischemia or atresia.

Four newborn patients with congenital syphilis and intestinal obstruction are discussed in this report. In three cases, the obstruction was due to inspissated meconium, simulating the features of meconium ileus in one, meconium plug in the second, and associated with perforation of the terminal ileum in the third. An exocrine pancreatic insufficiency and a motility disturbance of the intestine due to syphilitic infection during fetal life could be the probable etiologic factor. The fourth patient had multiple ileal stenoses. Ischemia due to the prenatal syphilitic arteritis of the bowel wall can be responsible for this pathology. Attention is drawn to the association between congenital syphilis and neonatal intestinal obstruction.

After a 30 minute period of superior mesenteric artery occlusion in adult rats, there was a significant decrease in peritoneal inflammatory reaction, ileus, peritoneal adhesion formation, and histologically proved bowel wall necrosis in animals given intravenous dimethyl sulfoxide at the end of the ischemic period. In contrast, control rats given normal saline solution intravenously demonstrated severe inflammatory reaction, ileus, hemorrhagic peritoneal fluid, extensive adhesion formation, and areas of bowel wall necrosis. Intravenous glycerol did not have the beneficial effect seen with dimethyl sulfoxide. Neither compound was effective when given intraperitoneally. We conclude that intravenous dimethyl sulfoxide has a significant protective effect in rats with acute intestinal ischemia due to the superior mesenteric artery occlusion in the rat.

A 13-year-old girl with meningomyelocele and a cauda-equina-paraplegia-syndrome, with resulting long-standing ileus, developed an extensive gangrene of the stomach, the small bowel and parts of the colon. As pathogenesis a non-occlusive-ischemia is suspected; the exceptional neurological situation is discussed.
