Of 6,099 children treated for malignancy, 16 (ages 3.5 to 18 years) developed acute appendicitis between 1962 and 1989. Fourteen had leukemia (ALL 10, AML 4). One each had rhabdomyosarcoma and Ewing's sarcoma. Active malignancy at diagnosis was noted in 10, 4 of whom had severe neutropenia (absolute neutrophil count less than 500/mm3). Of all the leukemics (2,794/6,099), abdominal pain during induction was a frequent complaint. The incidence of appendicitis, however, was low (0.5%). Nine of the 16 patients presented classically, facilitating prompt diagnosis and treatment. Six diagnoses were delayed. Three of these patients presented atypically with vague, nonlocalized pain, abdominal distention, lack of abdominal guarding, fever, dehydration, diarrhea, and unusual symptoms such as upper gastrointestinal bleeding. In each of these 6 patients the appendix was ruptured. Delays led to complications and deaths. Three patients required perioperative transfusions to treat excessive bleeding and two patients with ruptured appendicitis developed wound abscesses. Two patients died; in one, ruptured appendix was diagnosed only at autopsy. The other patient died of uncontrolled sepsis. Typhlitis occurring during induction chemotherapy may present similarly and is the main differential diagnosis. Typhlitis will usually improve with medical treatment alone. Nausea and vomiting (13/16), right lower quadrant pain (13/16), guarding (14/16), tachycardia (12/16), fever (10/16), and rebound tenderness (10/16) were the most frequent signs and symptoms of appendicitis. Persistent localized abdominal pain and guarding, lack of improvement with medical treatment, clinical deterioration, and the development of a mass were our indications for laparotomy. Despite major improvements in therapy, there is still a 37.5% error rate in our ability to accurately diagnose appendicitis in pediatric cancer patients.

The reliability of the signs and symptoms of acute appendicitis are reviewed. The wide variation in clinical findings when the different studies are compared can probably be explained by the huge quantity of retrospective studies. Migration of pain to the right iliac fossa and/or guarding/rigidity support the diagnosis of appendicitis. The diagnosis of appendicitis should be doubted when anorexia, nausea and vomiting are absent, when symptoms have persisted for more than 72 h without apparent perforation, or when tenderness in the right iliac fossa is absent. Presentation in proximity to menstruation, cervical dislocation tenderness and bilateral adnexal tenderness indicates pelvic inflammatory disease. Small children have high perforation rates because of their uniform response to many illnesses and relative inability to express themselves and cooperate. The clinical findings in young and old patients are similar, except for a higher rate of abdominal distension in old patients. With a more thorough knowledge of the signs and symptoms of acute appendicitis and a constant awareness of its possible presence, it should be possible to increase the diagnostic accuracy.

Four cases of diabetic ketoacidosis presenting with abdominal pain are reported. Case 1: a 14-year-old boy suffered from sudden onset of mid-abdominal pain, then migrating to the right lower quadrant. Nausea and vomiting occurred subsequently. Appendectomy was performed under the impression of acute appendicitis in an outside surgical clinic. The patient became comatose the next day and then was transferred to our hospital. Diabetic ketoacidosis was diagnosed after the detection of hyperglycemia, glycosuria, and ketonuria on the day of admission. Unfortunately, he expired on the same day in spite of vigorous resuscitation. Case 2: a 9-year-old boy complained of abdominal pain for 10 days. There was no specific finding in the physical examination. Diabetic ketoacidosis was confirmed four days later when conscious disturbance, dehydration, and tachypnea were noticed. Case 3: a 10-year-old girl presented with a history of intermittent abdominal pain for one month. The character of the abdominal pain was nonspecific. Glycosuria was detected in a pediatric clinic. Diabetic ketoacidosis was confirmed after her referral to our hospital. Case 4: a 5-year-old girl suffered from acute abdominal pain for four hours. She was found to have tachypnea, lethargy, and ill-looking. Diabetic ketoacidosis was diagnosed after serial examinations. The abdominal pain in diabetic ketoacidosis may lead the pediatrician into diagnostic error. Therefore, when a child presented with non-specific abdominal pain, a routine urine sugar should be checked in order not to miss the possibility of diabetic ketoacidosis.

Twenty-four pregnant women with acute appendicitis received exploratory laparotomy during an 8-year period. Abdominal pain accompanied with nausea and vomiting were the most common symptoms. Abdominal tenderness and rebounding pain were the most reliable physical signs. Leukocytosis with WBC count greater than 15,000/cu mm and granulocytes greater than 87% and prolonged symptomatic duration were indications that appendiceal perforation might have occurred. A McBurney's incision and spinal anesthesia were preferred for appendectomy during pregnancy. In cases of uncomplicated appendicitis, tocolytic agents and antibiotics were not routinely used. Premature labor occurred in 21% of patients during postoperative period.

A retrospective study of 201 patients, 152 with simple and 49 with complicated, appendicitis is presented. Diagnosis of simple acute appendicitis was made on symptoms of abdominal pain, anorexia, nausea and vomiting, together with rebound abdominal tenderness and not on white blood cell count. Normal white blood cell count was found in 80.3% cases of simple acute appendicitis while elevated white cell count was associated with 85.7% of complicated appendicitis. There was no mortality in 152 patients who had appendectomies for uncomplicated acute appendicitis, but the mortality rate in the 49 patients with complications was 12.2%. This was responsible for the overall mortality rate of 3% for all appendectomies in this report. Complicated appendicitis in this review was largely due to pre-admission delays and the ingestion of strong cathartics, both of which could not be influenced by surgeons.

The etiology of cecal diverticulitis remains unclear. The majority of diverticula are solitary and probably false and may be the result of the same degenerative process seen in the more common left-sided diverticulosis. A minority are true diverticula and may be of congenital origin. Cecal diverticulitis is clinically indistinguishable from acute appendicitis although patients with cecal diverticulitis tend to be older (average age, 40 years), have a longer duration of symptoms, and present less often with nausea and vomiting. In patients with previous appendectomy and in those with more indolent symptoms, barium enema may be helpful in making the diagnosis. If nonoperative treatment is chosen, careful follow-up with air contrast barium enema and colonoscopy should be carried out. The majority of patients require surgery and two types of cecal diverticulitis are encountered at laparotomy. The usual type, accounting for two thirds of cases, is easy to recognize, has an inflamed projection from the cecal wall, and is dealt with by a limited local diverticulectomy. Some authors advocate nonsurgical treatment for this first group of patients. Incidental appendectomy is advocated to avoid confusion should symptoms occur postoperatively. The hidden variant presents as a large, indurated phlegmon and is difficult to distinguish from a perforated cecal carcinoma. With the hidden variant, right hemicolectomy is the surgical treatment of choice and carries a 1.4 percent mortality.

Duplications of the alimentary tract are unusual congenital anomalies that frequently present a diagnostic as well as therapeutic challenge to the surgeon. Because these lesions occur so infrequently, they are often not suspected until encountered intraoperatively. Due to the complicated anatomy and common blood supply shared between the duplication and associated native bowel, appropriate management requires a familiarity with the anatomy and clinical characteristics of this entity. To better define the range of patient characteristics, clinical presentation, and preferred therapy, 20 enteric duplications were reviewed in 17 patients treated at the Children's Hospital Medical Center from 1956 to 1986. Ages of patients ranged from 1 day to 11 years; 60% were less than 2 years of age at initial presentation. Seven duplications in six patients involved alimentary tract structures of foregut derivation (esophagus, stomach, and Parts I and II of duodenum), with a predominance of girls (4 of 6). Most of these patients (67%) presented with moderate to severe acute respiratory distress and a mass present on chest radiograph. In 67% of the patients, the correct diagnosis was established before operation. None required emergency operative intervention. By contrast, 13 duplications in 11 patients were of midgut or hindgut derivation (Parts III and IV of the duodenum, jejunum, ileum, and colon). In this group of patients, 62% of the duplications involved the cecum, 23% involved the ileum, and 16%, the jejunum. Seventy-eight per cent of the patients were boys. The most common symptoms were nausea and vomiting, and the most common sign was a palpable abdominal mass. Emergency operative intervention was required of eight of 11 patients with duplications involving the small bowel and colon. Three patients presented with an intussusception, four with signs and symptoms consistent with acute appendicitis, one with a small bowel obstruction, and two with gastrointestinal hemorrhage due to the presence of ectopic gastric mucosa within the duplication. It was found that two important points must be considered in regard to the management of enteric duplications: (1) the common blood supply shared between the duplication and native bowel must be carefully protected to avoid undue sacrifice of normal bowel, and (2) the presence of heterotopic gastric mucosa in 35% of patients negates internal drainage.(ABSTRACT TRUNCATED AT 400 WORDS)

A case of acute appendicitis in a 26-year-old woman apparently caused by a Copper-T IUD inserted 4 years previously is reported. Only 6 previous cases of this rare complication are recorded in the world literature. The woman was admitted as an emergency with a 12 hour history of epigastric pain radiating to the right iliac fossa and right lumbar region and associated with nausea and vomiting. The woman had had 2 children and 1 miscarriage. At admission her axillary temperature was 37.6 degrees Centigrade and her rectal temperature was 38.8 degrees Centigrade. She was tender in the right iliac fossa. On vaginal examination she was noted to have an IUD in situ. The woman had become pregnant and an abortion was performed. The IUD was not recovered. The possibility that the IUD had perforated the uterus was not considered, and 1 month following the termination a 2nd IUD (a Lippes Loop) was inserted. A diagnosis of acute appendicitis was made. The abdomen was opened through a McBurney incision. There was an inflammatory mass which included omentum involving the appendix with dense adhesions to the caecum. After dissection, a short and inflamed appendix was found with an IUD emerging from its proximal third. An appendectomy was performed. The right tube and ovary were noted to be mildly inflamed. The uterus appeared normal. No perforation site was observed, and the abdomen was closed. In this case it seemed likely that the IUD had perforated the uterus at the time of its initial insertion. The manner in which the device reached the appendix is unknown. In any instance of a "missing" IUD, an abdominal X-ray, ultrasound, or hysterography is indicated to exclude perforation and/or migration. If perforation of the uterus has occurred, the IUD should be recovered either by laparoscopy or, if necessary, laparotomy.

A case of small-bowel obstruction occurred secondary to an uncommon parasitic disease, anisakiasis. Intestinal obstruction is a rare manifestation of this disease. Anisakiasis may be seen initially with nausea and vomiting or may mimic acute appendicitis or Crohn's disease. The predisposing factor in all cases is the ingestion of raw fish, and the disease is preventable by cooking fish at greater than 60 degrees C for a short time or by freezing at less than -20 degrees C for more than 24 hours. Anisakiasis should be considered in the differential diagnosis of small-bowel obstruction in patients whose diet includes raw fish.

Goblet cell carcinoids of the vermiform appendix are uncommon. A comprehensive review of the literature revealed about 100 reported cases. Clinical presentation included: asymptomatic patients, acute appendicitis, and/or chronic intermittent lower abdominal pain with or without a palpable mass. We report the case of a 57 year-old woman with lower abdominal pain, nausea and vomiting. Normal blood tests. X-ray of the abdomen showed dilated small bowel loops with fluid levels. Initially, conservative treatment was started. After three days with no clinical improvement, the patient was operated on. An appendicocecal inflammation was found and a terminal ileum plus cecal resection with an end-to-side anastomosis was performed. The pathological diagnosis was goblet cell carcinoid. The patient shows no evidence of recurrence after 1 year follow-up.
