The physiologic effects of fluid resuscitation were studied in 20 piglets with advanced small bowel obstruction. Two solutions were compared: 5% albumin in normal saline and normal saline. Animals resuscitated with albumin-containing solution showed higher serum colloid oncotic pressure, greater loss of peritoneal fluid, lower urine output, and progression of muscular dehydration, when compared to animals resuscitated with similar volumes of normal saline solution.

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.

Despite the advantages of aseptic nonoperative intubation of the small intestine for decompression of obstructed loops, 48% of the attempts lead to failure to pass the tube through the pylorus. The difficulty and inconvenience of passage beyond the stomach have been overcome by the development of a special tube attachment adapted to a fiberoptic duodenoscope (Olympus Model GIF-K). Under direct endoscopic vision the tube can be carried into the second and third portion of the duodenum, released from the scope, and then further prodded into the jejunum. The entire procedure takes less than 15 minutes. Rapid intubation has now been easily carried out in five patients. Three patients had mechanical bowel obstruction. Rapid and effective decompression allowed adequate time for stabilization of concomitant serious problems such as (1) marked cardiopulmonary dysfunction secondary to a near fatal pulmonary embolus, (2) severe peritonitis post appendectomy, and (3) acidosis and dehydration. Surgical correction of the obstructing lesions was safely deferred for up to one week until the concomitant problems improved. The fourth patient, who was a renal transplant recipient, had chronic gastric ileus secondary to duodenal ulcer. Rapid passage of the long tube into the jejunum allowed restoration of nutrition and avoidance of gastrostomy. The fifth patient, with an ileus secondary to an infected abdominal aortic graft, underwent successful decompression but died of sepsis. He represents the only mortality. We propose that jejunal intubation using our technic is not only rapid but relatively easy and should encourage the wider acceptance of aseptic long tube intestinal decompression.

Fifty-one children under the age of 10 years admitted to a general hospital in Trinidad had a confirmed diagnosis of malrotation of the intestines. This was the primary diagnosis in 20 cases. Analysis of the records of these 20 revealed that one-half were less than 1 month of age at first presentation. Vomiting was a universal complaint, and nearly two-thirds were malnourished. Disturbed bowel habit, anorexia and abdominal pain were also reported. In 30% (six of 20) there were signs of dehydration; an equal number had features of intestinal obstruction. Radiological investigation provided the diagnosis in all but one child, who underwent surgical exploration with a provisional diagnosis of appendicitis. Although a volvulus was found in 35% of cases, no resections were necessary. A high rate of morbidity and a mortality rate of 15% highlight the problems involved in the surgical care of young infants.

Eighty consecutive patients presenting with complete large intestinal obstruction from primary carcinoma were evaluated. A multivariate analysis was performed to evaluate perioperative morbidity and mortality. There were five deaths in the immediate postoperative period (30 days). Extensive and lesser complications occurred in eight and 11 patients, respectively. There were 25 lesions of the right colon, whereas in 55 patients, the lesion was located distal to the left branch of the middle colic artery. Females were more likely to present with obstructed carcinomas of the left colon than males. Patients with an obstruction of the left colon more frequently presented with dehydration than those with a tumor of the right colon (p less than 0.05). Most carcinomas of the right colon were resected, whereas lesions of the left colon were managed with diverting colostomy in 33 patients and by primary resection in 22. Thirteen patients with carcinomas of the left colon had an immediate anastomosis without mortality. Preoperative severe cardiopulmonary disease, Acute Physiology and Chronic Health Evaluation score and advanced carcinoma (Dukes' C or D) were statistically related to early hospital morbidity and mortality, while individual physiologic parameters, site of lesion or operation performed were not. Primary resection may be performed safely in selected patients. Multivariate assessment and clinical staging may allow for appropriate patient selection and improve immediate outcome.

Four hundred consecutive hip fractures were studied prospectively. Two hundred forty-seven patients were classified as unhealthy (poor cardiac status, pneumonia, cancer history, bowel obstruction history, malnutrition, dehydration, stroke history, renal failure history, cirrhosis). Twenty-two percent of this unhealthy group died, while only 6% of the remaining healthy group died. Death rates varied with admission activity level and mental status but not when patient health status was factored out. After factoring out health status, age was associated with higher death rates only in patients older than age 85. Confusion, a change of mental status in the hospital, occurred in 25% of patients. Confusion was associated with a medical complication in 94% of cases, was the presenting symptom of a medical complication in 79% of cases, and was associated with a 39% death rate. Major medical complications occurred in 9% of the healthy group (29% of them died) and 21% of the unhealthy group (64% of them died). Major medical complications in unhealthy, shut-in patients were associated with an 80% death rate. Vigorous urinary tract monitoring and early treatment of bacteriuria decreased death rate. Postfracture malnutrition was associated with higher complication rates. Hip surgery performed within 72 hours on patients with acute medical illnesses in addition to their fracture was associated with a higher death rate. Whether a patient walked postfracture seemed not to be correlated with the death rate. Patients who were not walking prefracture but treated by internal fixation had a 34% failure rate.

Late onset congenital diaphragmatic hernia is a rare condition that is difficult to diagnose. Complications such as intestinal obstruction and digestive perforation may occur. A previously healthy three year-old girl was admitted to hospital with dehydration, shock, and ketoacidosis. A chest X-ray film showed a left hydropneumothorax with an indefinable left diaphragm, that was confirmed by ultrasonography. Hexabrix introduced through a nasogastric tube showed opacification of the left hemithorax attributed to an intrathoracic gastric perforation. She recovered after surgery. Gastrointestinal complications of delayed congenital diaphragmatic hernia must be promptly recognized since surgery should not be delayed.

An 8-week-old infant presented with vomiting and failure to thrive due to small bowel obstruction caused by a diffusely enlarged pancreas. Surgical bypass of the obstruction was followed by secretory diarrhea, hypokalemia, and dehydration. Plasma vasoactive intestinal peptide (VIP) (823pg/ml), pancreatic polypeptide (4,500 pg/ml), and neurotensin (680 pg/ml) concentrations were markedly elevated. No neoplastic process was identified. Therapy with the long-acting somatostatin analogue SMS 201-995 was followed by decline in VIP concentrations (900 to 200-300 pg/ml), decrease in stool frequency, and normalization of serum electrolytes. During 12 months of somatostatin analogue therapy, length and weight progressed along the 3rd percentile on the Tanner growth chart.

Feeding animals large quantities of dry hydrophilic fiber sources, such as psyllium husk or guar gum, may lead to intestinal obstruction or to other mechanical effects unrelated to the normal function of these materials in human diets. Such fiber sources should be hydrated prior to feeding, rather than being incorporated into dry diets as is. The water-holding capacity of psyllium hydrophilic mucilloid, for example, is greater than or equal to 40 g/g, compared to 2-3 g/g of wheat bran. Consumption of the psyllium product dry would be much more likely to produce intestinal dehydration than would consumption of dry bran. Because of possible untoward effects of high levels of these materials, it may also be more appropriate to feed such fiber sources in quantities approximating that of their potential human dietary consumption, rather than very high quantities that would be unlikely to be attained in human diets.

Patients with intussusception who have necrotic bowel requiring bowel resection or who are at major risk of perforation from attempted hydrostatic reduction may be better managed without barium reduction. Ideally, the clinician would like to identify such patients at presentation. Two groups of patients, representing the extreme ends of the intussusception treatment spectrum were investigated in order to highlight the clinical features of patients in whom an attempted barium reduction is not justified. A group of 200 patients who had successful and safe hydrostatic reduction was compared with 104 patients who ultimately required bowel resection. Four features were found to be indicators of an increased likelihood of resection: age 3 months or less, or greater than 2 years, duration of symptoms greater than 24 h, presence of small bowel obstruction on plain radiology, and clinical assessment of dehydration greater than 5%. The validity of these features as prognostic indicators was assessed by applying them to all patients who had attempted barium reduction to see how they predicted patient outcome. In isolation, each feature was found to be compatible with a safe and successful hydrostatic reduction. The rate of resection was increased in patients with multiple adverse features and in these patients the enema technique may require modification. Patients with three or four adverse features had an unacceptably high incidence of gangrenous bowel requiring resection and a low likelihood of successful hydrostatic reduction. It is believed that attempts at reduction are not appropriate in these patients.
