Percutaneous aspiration biopsy of abdomen and retroperitoneum.

Percutaneous fine needle aspiration biopsy was performed in 38 patients. Adequate material for histological diagnosis was obtained in all. No false positive results were obtained and there was only one false negative result. The procedure was without complication in all patients. The biopsy material was obtained by the radiologist in the X-ray department following localisation of the lesion by ultrasound. The advantages of the early use of this technique in the evaluation of patients presenting with suspected mass lesions in the abdomen and retroperitoneum are described, and its contribution to the formulation of further patient management stressed.

The acute abdomen in the immunologically compromised child.

From 1976 through 1982, 35 children with leukemia (27), aplastic anemia (4), and solid tumors (4), were evaluated for symptoms and signs of acute abdominal disease. Twenty-six patients required 34 operations, 14 of them for life-threatening events. Sixteen patients received a bone marrow transplant. The most common surgical emergencies were for acute massive Gl hemorrhage (10), biliary tract disease (4), and typhlitis (3). Thirteen (37%) of the children are alive and free of disease, 22 (63%) have died, 13 of them as a direct result of the abdominal complication which occurred. Alterations in the immune system and hematopoietic system caused by the malignant disease and its treatment with chemotherapy and irradiation appears to be responsible for a number of abdominal complications which the surgeon is asked to see. When symptoms and signs of an acute abdomen develop in patients with leukemia or solid tumors, prompt, thorough evaluation and early aggressive surgical treatment is needed if the patient is to survive. The surgeon should be aware of the unusual array of abdominal complications which can occur in this population of patients.

Ventriculoperitoneal shunt infection masquerading as an acute surgical abdomen.

Shunting of cerebrospinal fluid to the peritoneal cavity has brightened the outlook for children with hydrocephalus. Nine hundred sixty-nine primary ventriculoperitoneal shunts were inserted for hydrocephalus between 1970 and 1981. During this same period, 2205 shunt revisions were performed in 847 children, some of whose primary shunt had been inserted prior to 1970 or at other institutions. Nineteen patients with a ventriculoperitoneal shunt infection persented with abdominal pain, fever, and abdominal tenderness; each had acute peritonitis. Three underwent laparotomy with the preoperative diagnosis of appendicitis; however, only infected peritoneal fluid and nonobstructing adhesions were found. A fourth child underwent an unnecessary intestinal resection at another hospital and required prolonged nutritional support and treatment of severe postoperative complications. Fifteen children who presented with an "acute surgical abdomen" were managed with intravenous fluids, gastric decompression, antibiotics, and removal of the intraperitoneal shunt. External ventricular drainage was employed until the cerebrospinal fluid was sterile. The shunt was then internalized in the peritoneal cavity. The abdominal signs and symptoms improved after removing the peritoneal tubing in all children. This plan of therapy has eliminated unnecessary laparotomy in those who may require repeated procedures for control of hydrocephalus.

Streptococcal sepsis presenting as acute abdomen in a child with transient hypogammaglobulinemia of infancy.

Group A streptococcal sepsis was documented in a child who presented with an acute abdomen. Massive retroperitoneal edema was observed at laparotomy with no focus of infection. Immunologic evaluation revealed low serum immunoglobulins and deficient in vitro IgG synthesis consistent with transient hypogammaglobulinemia of infancy. Unusual or severe infections in infancy should be evaluated for congenital immunologic disease.

Approach to the acute abdomen.

As our population ages, more patients will be presenting with acute abdominal problems which require attention. Unlike younger patients, the aged present later in the course of their disease and also often have concomitant underlying diseases. The diagnosis of an acute abdomen is further complicated by the relative lack of physical findings which is due to the elderly's lack of pain perception. The surgical problems in the elderly also tend to be more rapidly life-threatening than in younger patients. This further emphasizes the need for rapid diagnosis should an elderly patient present with abdominal pain. Methods to decrease the mortality from acute surgical problems are limited, but are potentially very effective. The first is to arrange for elective correction of the problem should it be known, and the second is to refer the patients promptly for operative consideration before sepsis becomes firmly established. Exact diagnosis before referral, while intellectually satisfying, is often contributory to a poor outcome in these patients.

Subcutaneous fat in the fetal abdomen as a predictor of growth restriction.

OBJECTIVE: To determine if measuring fetal abdominal fat antenatally using ultrasound can predict fetal growth restriction (FGR). METHODS: One hundred thirty-seven unselected women with singleton pregnancies had serial ultrasound scans at 20, 26, 31, and 38 weeks' gestation. Subcutaneous fat in the fetal abdomen was measured using the same section as the abdominal circumference (AC). Outcome measures were birth weight, neonatal morbidity, and ponderal index. RESULTS: Infants with subcutaneous fat less than 5 mm at 38 weeks (n = 51) were almost five times more likely to have a birth weight below the 10th centile than those with subcutaneous fat of 5 mm or more (n = 75). The incidence of neonatal morbidity was significantly higher in infants with subcutaneous fat less than 5 mm, compared with those with subcutaneous fat of 5 mm or more (20% versus 8%, P < .05). Decreased subcutaneous fat was also associated with a high prevalence of low ponderal index, regardless of birth weight category. CONCLUSION: Measurement of fat in the abdominal wall is a simple technique with a sensitivity for predicting low birth weight similar to that of conventional sonography and might potentially predict FGR irrespective of fetal weight.

Selective role of nuclear medicine in evaluating the acute abdomen.

The imaging evaluation of the acute abdomen has clearly evolved with the introduction of high-resolution imaging techniques, such as CT, US, and MR imaging, leaving scintigraphic examinations an important, though selective, role based on their noninvasive, physiologic, and functional nature. Proper use of these examinations among all the diagnostic methods requires a good understanding of their strengths and limitations.

Ultrasonography of the acute abdomen: gastrointestinal conditions.

Although multislice, helical CT is increasingly replacing ultrasonography for the evaluation of patients with acute abdominal pain, ultrasound does have certain specific advantages over CT. This article discusses the advantages of ultrasound in imaging of the acute abdomen, exploring such areas as appendicitis, ileocecal Crohn's disease, infectious ileocolitis and infectious ileocecitis, mesenteric lymphadenitis, cecal carcinoma, sigmoid diverticulitis, right-sided colonic diverticulitis, and perforated peptic ulcer.

Antibiotics for the acute abdomen.

Antibiotics are only an adjunct to proper surgical therapy for the treatment of the acute abdomen associated with bacterial secondary peritonitis. Upon presentation, all patients require a preoperative dose of antibiotics for prophylaxis against infection of remaining sterile tissues. Patients found intraoperatively to have an established peritoneal infection benefit from an immediate postoperative course of therapeutic antibiotics. A regimen that adequately covers facultative and aerobic gram-negative bacilli and anaerobic organisms is essential. The duration of therapeutic antibiotics is probably best decided on an individual patient basis. The goal of antibiotics is to reduce the concentration of bacteria invading tissues. The pathogens of bacterial peritonitis are influenced by such factors as the patient's pre-existing chronic diseases, state of acute physiologic debilitation, immunocompetence, recent antibiotic use, recent hospitalization, and neutralization of gastric acidity. Intraoperative peritoneal cultures are most useful in patients suspected of having impaired local host defenses. In these patients, all identified organisms, such as Enterococcus or Candida, may be potential pathogens. The common practice of administering empiric and prolonged courses of broad-spectrum antibiotics in patients who manifest persistent signs of inflammation may be more harmful than beneficial. These patients warrant an exhaustive search for extra-abdominal and intraperitoneal sources of new infection. Otherwise, such use of antibiotics may continue to promote the selection of bacteria that are highly resistant to conventional antibiotics and permit the overgrowth of organisms commonly seen with tertiary peritonitis. The best chance of resolving bacterial peritonitis is through early, aggressive surgical management complemented by short courses of potent antibiotics and appropriate physiologic support. Through these efforts, the clinician tries to help the systemic inflammatory response to benefit the host and not become unregulated, result in MOFS, and produce a high mortality.

The open abdomen. The Marlex mesh and zipper technique: a method of managing intraperitoneal infection.

In conclusion, a zipper technique has been outlined that allows effective continuing drainage of the septic abdomen, permits early diagnosis of organ damage, is rapid and cost effective, minimizes ventilator dependency and gastrointestinal complications, is well tolerated by the patients, and has produced a modest 65 per cent survival rate in the first 34 critically ill patients in whom it was used. Selection of patients is critical. It is a technique that must not be undertaken lightly but that appears to have life-saving potential.

Computed tomography and magnetic resonance imaging of the acute abdomen.

CT is a noninvasive investigation that in many instances is more sensitive in elucidating intra-abdominal and retroperitoneal disease than is conventional radiography. With modern scanners, the procedure is rapid and efficient and suitable for the most severely ill and infirm. The scans are easily interpretable, and the anatomic and morphologic depiction of disease is readily understood by those with surgical training. Information regarding the state of the bowel wall, mesentery, and intraperitoneal and retroperitoneal structures is displayed in greater detail than by any other diagnostic imaging modality. The use of intravenous contrast medium is rarely essential. The concentration of iodinated contrast needed for opacification of the bowel is no greater than 2 per cent to 5 per cent and will not complicate bowel surgery, as would standard upper gastrointestinal or barium enema studies. Abscess, free air, calcium, and intraperitoneal fluid are very sensitively detected. CT is extremely useful in aiding surgical decision making in the acute abdomen and is complementary to or has replaced conventional studies.

Laparoscopic management of the acute abdomen, appendix, and small and large bowel.

The application of laparoscopy for diagnosis and treatment of the acute abdomen, appendicitis, and in the management of small and large bowel diseases is a natural step for the general surgeon. Acute appendicitis is a common general surgical problem that can be difficult to diagnose. Laparoscopy is an excellent aid in diagnosis and laparoscopic appendectomy can be performed easily. The controversy of incidental appendectomy and recommendations for management are discussed. Small and large bowel diseases and their surgical treatment now can be managed laparoscopically thus decreasing morbidity and mortality. The uses and limitations of these techniques are discussed as well as future trends in treatment.

Müllerian duct cyst extending into the abdomen.

Müllerian duct cysts occupying the pelvic/abdominal region are rare. We describe a müllerian duct cyst extending into the lower abdomen in a 47-year-old man complaining of urinary retention. We removed the cyst through a suprapubic retrovesical approach. No malignancy was found in the surgical specimen.

Acute diabetic abdomen in childhood.

Three children presented as acute surgical emergencies due to undiagnosed diabetes mellitus. Where diabetic ketoacidosis mimicks the acute abdomen three clinical features are important in reaching the right diagnosis-namely, a history of polydipsia, polyuria, and anorexia preceding the abdominal pain, the deep sighing and rapid respirations, and severe dehydration.

Meckel's diverticulitis secondary to carcinoid tumor: an unusual presentation of the acute abdomen in an adult.

This case reports the concomitant findings of carcinoid tumor within a Meckel's diverticulum presenting as an acute abdomen in an adult male. Most Meckel's diverticula remain asymptomatic throughout life, and symptomatic diverticula are virtually nonexistent in older adults. Meckel's diverticulitis is clinically indistinguishable from acute appendicitis, and abnormal or symptomatic diverticula are generally resected. Surgical treatment of Meckel's diverticula is recommended for children during exploration. However, resection is controversial in asymptomatic adults. Carcinoid tumors are the most common primary tumor of the small bowel. The duration of symptoms before diagnosis varies from 2 to 20 years, and half of all patients have incurable abdominal disease at first-look surgery. Metastatic events occur most commonly in the liver with a generally poor prognosis. Surgical resection is the treatment of choice. Both Meckel's diverticula and carcinoid tumor are rare clinical entities, and carcinoid tumors occurring within a Meckel's diverticulum are even more uncommon. Thus, the natural history is difficult to predict and treatment recommendations vary. Solitary, localized, asymptomatic nodules less than 1 cm are generally managed with diverticulectomy or segmental resection. Larger or multiple lesions require wide excision of bowel and mesentery, and hepatic resection may be required for metastatic disease.

Syndrome of the rectus abdominis muscle mimicking the acute abdomen.

The syndrome of the rectus abdominis muscle is a disorder of unknown etiology that produces rupture or tear of the epigastric artery, and stretches the rectus cutaneous medialis nerve, producing excruciating pain. The disorder is misdiagnosed in 60% to 93% of cases. We report two cases that presented as acute abdomen. One helpful diagnostic test was the lidocaine test, accomplished by subcutaneous injection of lidocaine into the sheath of the rectus abdominis muscle near the rectus cutaneous medialis nerve; the procedure provided immediate pain relief and the patients remained asymptomatic. In addition to helping establish a diagnosis quickly the lidocaine test may spare the patient the unnecessary morbidity or mortality of more invasive procedures.

Extramammary Paget's disease recurring on the skin of the lower abdomen and entire right leg two and half years after simple vulvectomy for minimally invasive Paget's disease of the vulva.

We encountered an unusual case of extramammary Paget's disease (EMPD) recurring on the skin of the lower abdomen and entire right leg two and a half years after simple vulvectomy for minimally invasive Paget's disease of the vulva. Histologic examination of the skin metastases demonstrated that the proliferation of Paget cells was confined to the dermis, most of them were located in lymphatic vascular spaces. This case confirms that minimally invasive Paget's disease of the vulva may sometimes be an aggressive disease. We consider that lymphatic metastases already existed in this patient at the time of initial surgery; thus, the recurrence of EMPD on extragenital skin sites may have been prevented if initial treatment would have included radical vulvectomy and bilateral groin lymph node dissection instead of simple vulvectomy without groin lymph node dissection.
