The correct and early diagnosis and treatment are essential for the outcome of the patient with an acute abdomen. In 520 patients with the initial diagnosis of acute abdomen early laparoscopy revealed certain advantages. 183 (35.2%) patients with 11 different diseases could be treated laparoscopically, 129 (24.8%) underwent a laparotomy. In 96.7% of our patients the initial diagnosis was correct, so that these patients received a suitable therapy. The method is economically justified because we have equal costs both with CT/szintiscanning and laparoscopy, whereas the costs of MRI are nearly 400 DM higher.

A 19-year-old man was admitted with fever, haematuria, general malaise, pain on the left side of the pelvis and a full feeling in the left lower abdominal quadrant of the abdomen. His history mentioned a varices operation. During admission he developed an acute abdomen and deep vein thrombosis in both legs. CT of the abdomen showed a pathologic mass and absence of the vena cava inferior. Laparotomy revealed extensive thrombosis in widened veins. Clinical improvement occurred following adequate thrombolysis. Congenital absence of the vena cava inferior results from aberrant development during organogenesis. Patients are typically asymptomatic, but may present with venous insufficiency at a young age and deep vein thrombosis. Absence of the vena cava inferior can be accompanied by other congenital abnormalities such as dextrocardia and congenital heart diseases. Diagnosis is made using CT or MRI. Treatment consists of lifelong anticoagulant therapy and, if necessary, surgery.

A case of an enlarged pelvic spleen, studied with MRI and MR angiography (MRA), is presented in a 32-year-old female wishing to become pregnant. An ectopic located spleen may be complicated by an acute abdomen due to torsion of the splenic vascular pedicle, resulting in splenic infarction. Displacement of the spleen and splenic pedicle during pregnancy may further increase the risk of torsion. Urgent splenectomy during pregnancy is associated with a high fetal and maternal mortality and morbidity. On the other hand, elective splenectomy of a pelvic spleen before pregnancy can result in adhesion formation, compromising the patient's fertility. The abilities of MRI and MRA in predicting the risk of these life-threatening complications during pregnancy are discussed, in order to evaluate the benefit-risk ratio of surgical treatment by splenectomy of splenopexia.

Diagnostic laparoscopy began in a surgical unit in a developing country in 1972. The developers of this technique aimed to hasten diagnosis, reduce patient distress, and improve bed utilization in an overcrowded teaching hospital wherein simple investigations such as x-rays took weeks to materialize. Over a period of 18 years reaching to 1990, 3,200 diagnostic laparoscopies were performed on adults under local anesthesia with no mortality, a complication rate of 0.09%, an 84% diagnosis rate, and 74% undergoing histologic biopsies targeting a wide spectrum of pathology. The equipment cost spread out over the 3,200 patients works out to 30 rupees (0.60 dollar) per patient. With the availability of noninvasive diagnostic aids such as ultrasound, computed tomography, and magnetic resonance imaging used US, CT, MRI under the control of target biopsy, the role of diagnostic laparoscopy has altered. Since 1990, clinicians have had the sophistication of the video camera and the pneumoperitoneum insufflator. Diagnostic laparoscopy is used for the evaluation of liver and peritoneal pathology, abdominal tuberculosis, malignancy, acute abdomen, and abdominal trauma. It often is a prelude to laparoscopic treatment of the underlying pathology, specifically in cases of acute appendicitis.

Although the spontaneous rupture of adrenal pheochromocytoma is rare, it can be lethal because it can induce serious changes in the circulation. We describe a 32 year old man with bilateral pheochromocyroma presenting as abdominal pain. In the emergency room, an abdominal MRI showed an aneurysmal vessel in the right adrenal mass and accompanying hemorrhage around the tumor capsule. The bleeding site was found by transfemoral abdominal angiography. Coil embolization was done in the bleeding vessels, specifically branches of the right adrenal artery. The hemorrhage was successfully controlled and vital signs of the patient were restored. Following emergency care, biochemical and imaging studies showed compatible findings of a bilateral adrenal pheochromocytoma. Postoperative histologic findings confirmed these observations. A ruptured pheochromocytoma should be considered as a cause of acute abdomen in cases of a concomitant adrenal mass. Intratumoral aneurysmal bleeding may be a cause of ruptured tumor, and careful angiographic intervention will help to ensure safe control of bleeding in such an emergency situation, even in cases of bilateral tumor.

Intussusception is defined as the telescoping of one segment of the gastrointestinal tract into an adjacent one. It is relatively common in children and is the second most common cause of an acute abdomen in this age group. It is much less common in adults and accounts for less than 5% of cases of mechanical small bowel obstruction. Whereas the diagnosis is usually already suspected in children before imaging, it is often made unexpectedly in adults. In addition, although in children there is usually no specific underlying cause, an underlying lead point is often present in adults. Plain film radiography, barium studies and ultrasound imaging play major roles in both the diagnosis and management of this condition, and it is increasingly common for the diagnosis to be made by CT and MRI, particularly in adults. This pictorial essay reviews the imaging features that may be found in patients with bowel intussusception. As well as describing the imaging features of the more commonly used tests, we also stress the role of emerging technologies such as MRI using ultrafast half-fourier sequences with single shot turbo spin echo.

Do advances in MR imaging and Computed Tomography have encroached upon the private territory of Ultrasound-Doppler imaging on paediatric practice? Do the enthusiasm promoted by the use of CT on non traumatic acute abdomen in adult has contaminated the indomitable village of paediatric radiologist? Undoubtfully, Ultrasound-Doppler stayed the first imaging modality to perform. However, the habits are less crystallised than a few years ago. The goal of this article is to describe the ultrasound findings and the potential indications for MRI or CT in the major non traumatic abdominal paediatric emergencies.

The ovarian fibroma is a rare benign tumor originating from the connective tissue of the ovarian cortex. On occasion, the general surgeon may encounter ovarian fibroma while operating an acute abdomen. We present a series of 15 ovarian fibromas encountered in 13 patients over 11 years experience in our general surgical ward. Only four cases required emergency operations due to either tumors or adnexal torsion. High-resolution ultrasound scan with color Doppler suggested an ovarian fibroma in only ten cases, while CT and MRI were suggestive for the diagnosis in three other cases. Surgical treatment consisted of five ovarectomies, three adnexal resections and five total hysterectomies with bilateral salpingo-oophorectomy. Seven patients underwent laparoscopic surgery, four of them for an ovarian resection and in three for an adnexectomy. Laparoscopic approach has significant advantages by limiting parietal aggression with better cosmetic results, short hospital admission, lower costs, few postoperative adhesions and rapid recovery.

Giant colonic diverticulum is a rare entity first described in 1946 by Bonvin and Bonte. It may be congenital or acquired and the average age of presentation is 65. There are less than 150 reported cases in the literature. A large abdominal mass was detected during a routine physical examination in an 82-year-old man. CT scan showed a large air-filled mass, barium enema showed multiple sigmoid diverticula, but no communication with the mass was found. A diagnosis of giant sigmoid diverticulum was made, elective sigmoidectomy and resection of the diverticulum was performed with no complications. The clinical picture may be different, varying from asymptomatic to acute abdomen, intestinal perforation or fistula. It can be diagnosed with abdominal X-ray, CT scan, barium enema or MRI, but colonoscopy is not effective. There are two accepted theories of the pathophysiology of this entity: first, a congenital origin and second, that inflammatory diverticula are caused by a perforation with a ball-valve that allows gas to enter, but not to leave the cyst, thus, enlarging the false diverticulum, and progressively destroying the bowel layers, causing secondary fibrosis. Elective treatment is a segmental resection of the affected colon with the diverticulum and in cases of acute abdomen two-stage bowel resection is preferred.

Pheochromocytoma is a tumor of the chromaffin cells which secretes catecholamines and 90% of it originates from adrenal medulla. The main symptoms and signs are hypertension, tachycardia, sweating and headache. Rarely, acute abdomen may occur as a result of the rupture of tumoral mass or bleeding inside the mass. Here we present a 43 year old male patient who applied with acute abdominal syndrome and severe hypertension. Abdominal MRI showed a large mass hemorrhagic in nature above the right kidney. At laparotomy, ruptured adrenal mass was seen and excised successfully. The histological evaluation confirmed the diagnosis as pheochromocytoma. Ruptured adrenal pheochromocytoma is a mortal situation potentially and it should be considered in patients who present with an acute abdominal syndrome and hypertension or shock. It should be known that early diagnosis and surgery with proper preoperative treatment is a life saver.
