Five cases presenting in late infancy and childhood with symptoms and signs referable to malrotation of the midgut are described. The condition may present with jaundice, malabsorption or the signs and symptoms of intestinal obstruction due to internal hernia or volvulus. It may also result in volvulus and gangrene of the midgut. A short root of the mesentery predisposing to this event will be seen on a barium meal and follow through examination and will warn of its impending occurrence.

Twenty-five patients with traumatic diaphragmatic hernia discovered at least five months after injury are described, of whom 18 were male and seven female. All but one hernia occurred on the left side. Stab wounds were the etiological factor in 22 patients and blunt trauma in three. The diagnosis was most often made by a chest or abdominal radiograph, but barium ingestion confirmed the diagnosis in ten patients. Intercostal drainage of gastric contents provided the diagnosis in two patients. In all nine patients initially approached by a thoracotomy or a thoracoabdominal incision, the hernia was easily reduced and the defect repaired. Although reduction and repair were easily accomplished by the abdominal route in seven patients, this approach was unsatisfactory or inadequate in six others. The colon and stomach were usually in the chest, and strangulation occurred in five patients. The mortality was 20% but rose to 80% when gangrene was present.

In addition to echinococcal cysts and mycetomas, a wide variety of disorders can occasionally produce an air meniscus sign on a chest radiograph. A proposed classification follows: I. Infections A. Lung abscess (with or without pulmonary gangrene) B. Fungus ball C. Bacterial ball D. Tuberculoma E. Blood clot in tuberculous cavity, Rasmussen aneurysm F. Echinococcal lung cyst II. Neoplastic A. Bronchogenic carcinoma B. Primary lung sarcoma C. Metastatic carcinoma, sarcoma to lung D. Bronchial adenoma E. Cystic hamartoma III. Developmental A. Bochdalek hernia (pseudocavity) IV. Traumatic A. Pulmonary hematoma V. Hemodynamic A. Congestive heart failure (with or without bullae)

The theory is advanced that increased pulmonary vascular resistance, resulting in a state of fetal circulation, with right-to-left shunting through the ductus arteriosus, is the main reason that many patients do not survive after repair of a diaphragmatic hernia. Three patients are presented (who, by Raphaely's criteria, were destined for a fatal outcome) in whom the ductus was ligated, and vasodilator drugs were infused into the pulmonary artery. All three demonstrated definite improvement in oxygenation. Two expired after 6 days, one of whom was found at autopsy to have intestinal volvulus and gangrene, and the other multiple plumonary emboli. One case, so managed, survived. The suggestion is made that pulmonary hypoplasia is not the main reason for the high mortality rate after diaphragmatic hernia repair, and that additional laboratory and clinical investigation of the pulmonary circulation may lead to significant improvement in results.

Gangrenous bowel most often results from hernia, adhesions and mesenteric insufficiency. The overall mortality rate for 151 cases was 37%. This figure was 20% for hernia, 23% for adhesions and 74% for mesenteric insufficiency. In the latter category where bowel resection was feasable the mortality rate was 40%. Other causes of bowel gangrene had a mortality rate of 28%. In many instances the pathophysiologic processes were of such a nature that current medical expertise has not reached a level of development to effectively cope with the situation. There were, however, a significant number of cases where survival may have been achieved had it not been for deficiences on the part of the patient, the primary health care personnel or those in attendence at the referral center. The basic keystone for a successful outcome in the management of patients with the gangrenous bowel problem is early surgical intervention. All will be lost if patient exposure to this source of lethal toxins is allowed to proceed to an irreversible stage. Liberal antibiotic administration probably postpones the arrival of intractable hypotension. Other factors which can be expected to improve the survival rate include minimization of technical errors, repair of incidental hernias, elemination of dependence upon nasogastric tubes for the definitive management of patients with complete bowel obstruction (with one or two exceptions), and a firm commitment to the diligent pursuit and early definitive management of postoperative complications.

Transomental hernia is a very rare condition with less than 50 cases reported. This hernia nearly always causes bowel obstruction and may result in a high mortality rate because of strangulation and gangrene. A typical case of transomental hernia is presented and the literature is reviewed with emphasis on the need for early diagnosis and operation.

Elective repair of simple (uncomplicated) inguinal and femoral hernias avoids incarceration and bowel obstruction (complicated presentations). To identify factors that perturb this strategy, we analyzed the records of 1,859 consecutive nonpediatric patients with groin hernias. Incarceration or bowel obstruction prompted operation in 22 of 77 (29%) women and in 15 of 34 (44%) patients with femoral hernia. Patients presenting with bowel obstruction were significantly older than those with incarceration only and/or uncomplicated presentation, and 13 of 25 (52%) required resection of necrotic bowel. Mortality was limited to five patients of advanced age with groin hernia and bowel obstruction. Four of the five patients had undergone resection of necrotic bowel. Complicated presentations of groin hernias are associated with a higher proportion of women and patients with femoral hernias. Gangrenous bowel was encountered only in those patients with groin hernia and bowel obstruction. Early diagnosis and elective repair of uncomplicated hernias should remain our strategy in patients of all ages.

In a prospective evaluation of acute intestinal obstruction in emergency surgery, 3550 consecutive patients were studied. In the vast majority of patients (75%), obstruction was due to the external hernia, the inguinal hernia being by far the commonest type. However, the ascaris worm in children, volvulus of the sigmoid colon in adults, and intussusception in both children and adults, were significant causes of the disorder, and together accounted for 18% of the patients. Obstruction by the ascaris worm is easy to diagnose (by stool microscopy), and effective treatment (with antihelminthics) is readily available and cheap. A large number (90%) of the volvulus patients required resection for gangrene of the colon, thus arguing a strong case in support of laparotomy and inspection of the colon whenever feasible. A significant (41%) proportion of intussusception cases were adult, and in 33% of this group the lesion was associated with a tumour of the small bowel. The chief reason for death (10%) was late reporting to hospital.

Thirty-two patients with acute acalculous cholecystitis are presented. The age of the patients ranged from 1 to 80 years, with an average of 46.3 years. Acute acalculous cholecystitis occurred during the postoperative period in only four patients. Three patients were receiving total parenteral nutrition and 16 patients had one or more associated medical diseases. One patient had acute acalculous cholecystitis due to mechanical obstruction of the cystic duct caused by a diaphragmatic hernia. The most frequent signs and symptoms were right upper quadrant abdominal pain, nausea, vomiting, fever, abdominal mass, and jaundice. All patients were subjected to cholecystectomy. Nine (28.1%) gallbladder specimens had gangrene. Pericholecystic perforation was observed in four patients (12.5%) free perforation in one patient (3.1%), and empyema of the gallbladder in one patient (3.1%). Bacteria were cultured from 18 of 24 bile specimens. E. coli was the most common organism isolated. The overall postoperative mortality and complication rates were 15.6% and 40.6% respectively. The average hospital stay was 16.4 days.

Thirty-six thousand two hundred fifty abdominal hernia repairs were performed in U.S. Army medical treatment facilities during a five-year period. This study presents data about the type of hernia, incidence of complications by obstruction or strangulation, age, sex, and mortality. Hernias occurring with intestinal obstruction or gangrene (strangulation) are referred to as complicated hernias. Inguinal hernias in children less than two years of age, femoral hernias, and unusual (such as internal or obturator) hernias were found to have an increased incidence of complications. Surgical repair of ventral, umbilical, and femoral hernias was done with a low surgical risk and the presence of complications did not significantly increase this risk. An increased risk of mortality is associated with the repair of complicated unusual hernias and complicated inguinal hernias in patients more than 60 years of age.
