A case of dysplasia umbilico-fetalis is demonstrated. The malformation comprises a rare and strange reduction anomaly of the feto-umbilical unit, which is caused during early embryonic life (around the 7 mm stage, corresponding to the end of the third week of gestation). The cause of the damage is not known. The folding off of the embryo from the yolk sac and the development of the abdominal stalk are impaired. No abdominal wall is formed, and the umbilicus and umbilical cord are not developed. The abdominal organs are enclosed in a short amnion-mesoderm tube, which is bordered by the retroperitoneum at the fetal side and by the chorionic plate at the placenta side. The umbilical vessels are only a few centimeters long and traverse in the mesodermal layer of the amnion-mesoderm tube. The thin wall of the tube usually ruptures before birth, thus causing an abacterial fibrinoid peritonitis by the chemical irritation of the peritoneum through the constituents of the amniotic fluid. The lower extremities of the fetus reveal varying degrees of reduction deformities. One leg and large parts of the pelvis may be entirely missing, if the side of origin of the extremity is included in the amnion-mesoderm tube. Severe kyphoscoliosis is probably a secondary phenomenon. In addition, malformations of the inner organs occur such as caudal displacement and hernia of the diaphragma, hypoplasia of the lungs, dysplasia of the genito-urinary tract and non-rotation of the gut. The pathophysiology of the rare developmental defect and its secondary implications are discussed with special reference to related malformations such as omphalocele and infraumbilical defect of the abdominal wall.

The authors describe external intestinal fistulae found within 11 years at 5000 urgent operations on abdominal organs in 56 patients. 20 of them showed fistulae of appendicular origin, 15 developed fistulae following various traumas of abdominal organs, 1--after intestinal ileus, in 3 cases fistulae were due to incarceration of hernia, in 17 cases external fistulae were applied in intestinal neoplasms. Small gut fistulae were noted in 15, colon fistulae--in 41 patients. The total of 19 patients died, most of them had malignant intestinal neoplasms.

An omphalocele is a congenital defect of the abdominal wall, through which intestines and other intraabdominal organs protrude outside the abdominal cavity. The defect in the abdominal wall is covered by a translucent sac composed of peritoneum internally and amniotic membrane externally, through which the viscera can be seen. Such an anomaly is obvious and easily recognized at birth when the defect in the abdominal wall is large, but a small defect, also designated as umbilical cord hernia, is often unnoticed and may, when the cord is clamped, result in an iatrogenic laceration of the gut. We report such an encounter to alert the physician and suggest a method to prevent the iatrogenic misadventure. A careful follow-up of the child, including developmental evaluation, is presented and compared with her healthy twin. A review of the relevant literature shows that the anomaly is not rare and that there is often a delay of several days in establishing the correct diagnosis, leading to a fatal outcome in some cases.

Emergency equine abdominal surgery is easiest and most efficiently carried out with a team of surgeons. The surgical site should be as protected as possible by the use of sterile drapes and wound protectors. A ventral midline laparotomy incision has been found to be the most convenient approach to most equine intestinal obstructions. A standing laparotomy through the left paralumbar fossa gives adequate exposure for exploration of the abdomen and is, therefore, useful as a diagnostic tool. Horses tolerate having both ventral midline and left paralumbar laparotomy incisions well. If the cause of the intestinal obstruction is not readily apparent upon opening the abdominal cavity, a thorough systematic exploration of the abdominal cavity is necessary. If the problem cannot be found with the bowel in situ, intestine must be exteriorized for examination. The decision as to the extent of adequate bowel resection often depends on a subjective assessment of bowel function. In equivocal cases, the surgeon should choose to resect some normal bowel rather than taking a chance on leaving compromised bowel in place. Incarcerations are frequent causes of small intestinal obstructions. The small intestine may become incarcerated in the epiploic foramen, the inguinal canal or in an umbilical hernia. Thromboembolic compromise to intestinal vessels results in the longest lengths of embarrassed bowel requiring resection. Impactions are the most common obstructions associated with the caecum. Large colon torsions of 270 degrees or less may be corrected by surgical manipulation; with 360 degrees torsions of the large colon, however, vascular compromise is usually sufficient to devitalize this organ. Enterotomy of the large colon allows retrieval of most enteroliths from its lumen. Enterotomy of the right dorsal colon is also useful for removal of foreign bodies which cause obstruction of the most proximal portion of the small colon. In our Clinic a two-layer end to end anastomosis is usually utilized. Recently introduced automated stapling and ligating instruments have been useful in decreasing surgical time. Antibiotics, usually furacin and sodium or potassium penicillin in 2 litres of Normasol-R, are placed in the peritoneal cavity before closure of the abdomen. A Penrose drain is commonly placed into the abdominal cavity to provide drainage of the peritoneal cavity after surgery. The peritoneum is sutured with No 0 chromic gut in a simple continuous pattern. A second Penrose drain may be placed between peritoneum and ventral body wall, with its ends retracted through stab incisions in the skin. The linea alba is closed with simple interrupted sutures of stainless steel wire or No. 3 chromic gut. Employing the above described principles and techniques has increased the success of abdominal surgery in our Clinic.

Intestinal malrotation may be complicated by volvulus and intestinal necrosis. One hundred two children (64 male, 38 female) undergoing surgical abdominal exploration from 1977 to 1987 had malrotation. Fifty-two patients were less than 7 days of age, 13 from 8 to 30 days, 26 from 31 to 365 days, and 11 were older than 1 year of age. Of infants, 39 of 65 had 40-week gestations, 18 of 65 had 36- to 39-week gestations, and 8 of 65 had less than 36-week gestations. Chief symptomatology included: bilious emesis (47), intestinal obstruction (19), abdominal pain (11), and bloody stools (7). Seventy patients had congenital anomalies (50 single, 20 multiple). Diagnostic evaluations included 56 upper gastrointestinal series and 27 barium enemas. Each patient underwent correction of malrotation and appendectomy, and correction of congenital anomalies (omphalocele-9, gastroschisis-6, diaphragmatic hernia-7). Complications included short gut (2), sepsis (5), feeding difficulties (2), pneumonia (3), small bowel obstruction (2), and other (15). Nine patients (8.8%) died (trisomy 18-1, trisomy 13-1, intestinal necrosis-3, hepatic failure-1, prematurity-1, other sepsis-2). Two hundred sixteen children with intestinal malrotation have been treated from 1937 to 1987. Mortality rate has improved from 23% to 2.9%.

Forty-two patients of typhoid perforation of the gut have been studied. All the patients were subjected to surgery after resuscitation. Simple closure (with or without serosal patch) and temporary ileostomy were the commonly performed surgical procedures. The overall mortality was 14.2%. Postoperative morbidity included wound dehiscence, fistula, encephalopathy, septicaemia, intra-abdominal abscesses and incisional hernia. Faecal fistula formed in 5 out of 42 cases. Ileostomy was found to be the best procedure with regard to morbidity and mortality.

Lesions identical to those observed in human intestinal atresia (IA) have been experimentally reproduced in several mammal models by either mesenteric vessels or intestinal wall injury. The recent availability of an avian model led us to investigate whether the same lesions could be studied at less expense. An intestinal loop within the body stalk hernia was coagulated on the 12th incubation day in 427 chick embryos (group 3), the lesions were studied in survivors 4 days later under light and scanning electronmicroscopy (EM), and the findings were compared with those in 12 control embryos (group 1) and 14 sham-operated ones (group 2). Types I or II atresias were obtained in 61 (73.4%) of the 83 survivors in group 3. Seromuscular layers were normal at both ends of the lesion; there was some flattening of villi at the proximal, dilated end, and hyperplasia with apparently lengthened, branched villi at the distal, unused one. Mucosal pattern under light microscopy was strikingly close to that observed in human IA and in the fetal lamb experimental model. On the other hand, scanning EM showed that in this model there were no villi as such, but rather prominent mucosal folds that were regularly arranged in a tire-rubber pattern in the normal intestine, flattened and distended in the dilated one, and again roughly normal in the distal unused gut. High-power magnification scanning EM showed that enterocytes were normal at all levels but, in agreement with previous findings in the fetal lamb model, that intercellular spaces were widened in the dilated portion adjacent to the obstruction.(ABSTRACT TRUNCATED AT 250 WORDS)

Medical records of 210 horses that survived ventral midline celiotomy for at least 4 months were examined and owners were queried to determine factors contributing to incisional hernia formation. The incidence rate of incisional hernias within 4 months was 16%. Factors significantly associated with occurrence of incisional hernias were incisional drainage, closure of the linea alba with chromic gut suture material, previous midline celiotomy, excessive incisional edema, castrated male sex, postoperative leukopenia, and postoperative pain (colic). Factors not significantly associated with occurrence of incisional hernias were suture pattern used for linea alba closure, concurrent enterotomy or intestinal resection, postoperative bandage or stent, postoperative fever, hypoproteinemia, diarrhea, respiratory disease (coughing), and peritonitis. Hernias developed in horses within 12 weeks of surgery, with the earliest hernia recognized at week 2. Of 30 horses for which information was available, only one hernia developed in 24 (80%) and two or more hernias developed in 6 (20%) along the incision. Multiple hernias tended to be smaller than single hernias.

To identify the factors responsible for total parenteral nutrition (TPN) associated jaundice in the neonate, 77 newborns who had been started on TPN during the past 12 years had their charts reviewed. Forty-four (57%) of these infants developed jaundice during the 1st month of life. The incidence of jaundice was significantly higher in the presence of those diseases which were associated with impaired intestinal passage such as congenital duodenal atresia, jejunal atresia, etc, and those with an abnormal rotation of the gut such as diaphragmatic hernia, gastroschisis, etc. Thirty-two (42%) of these 77 infants had accompanying infectious signs, and 28 (88%) of those 32 infants with infectious signs developed jaundice. This incidence was significantly higher than that (36%) among those who had no infectious signs. Of the possible etiologic factors other than infection, neither the length of intrauterine life nor birth weight showed significant correlation with the incidence of jaundice. The incidence of jaundice tended to be higher in infants started on TPN at a younger age. There was no significant correlation between the incidence of jaundice and the duration of TPN or fasting period. Infants receiving 110 cal/kg/day or more during TPN developed jaundice significantly more frequently than those receiving fewer calories. No definite correlation was obtained between the incidence of jaundice and the amount of amino acids administered.

A 20-year retrospective study was made of children with congenital posterolateral (Bochdalek) hernias presenting more than 8 weeks after birth. The records of 26 patients (16 boys and 10 girls) were evaluated. Sixteen infants and children (62%) were originally misdiagnosed clinically and radiologically as having either infective lung changes, congenital lung cysts, or pneumothoraces; inappropriate thoracentesis occurred in four patients misdiagnosed as having a pneumothorax. Five patients had previously normal chest radiographs. The most useful investigation was a plain radiograph following passage of a nasogastric tube. Coexisting abnormalities (in particular, gut malfixation and malrotation) were common. All patients except one were operated on within days of presentation, and as emergencies if symptoms were acute. More than one third of our patients were left with a smaller than normal ipsilateral lung after their diaphragmatic hernia repair, and these lungs must be considered hypoplastic to some degree. Chest tubes made no difference in the lung's eventual expansion. Two deaths occurred as a result of acute cardiorespiratory arrest in previously well children. Therefore, the symptoms, signs, and radiologic findings of patients with diaphragmatic hernias presenting after the neonatal period may be difficult to interpret, and may result in diagnostic delay, misguided therapy, and a potentially fatal outcome.
