We reviewed the clinical and pathologic finding of 22 resected allografts from 19 of the 83 children who underwent a variety of small intestinal transplant procedures in the years 1990-2000 at the Children's Hospital of Pittsburgh. Resections were compared with prior mucosal biopsies because resections allow for evaluation of the entire bowel thickness, including the feeding vessels, and obviate the problems of limited sampling. Partial resections that were done soon after the transplant, or soon after additional surgery, were for surgical problems such as leaks, adhesions, and volvulus. None had biopsy features suggestive of rejection or infection. Partial resections done late (6 months or more) after transplantation were more likely to be related to allograft immune biology; two had a sclerosing peritonitis that was confined to the allograft, and one had an obstructing carcinoma arising in the allograft mucosa. One patient had a localized stricture, demonstrated to be due to graft vascular disease at partial resection, and this patient went on to have the allograft removed a year later for chronic rejection. Early complete allograft enterectomies were for refractory acute cellular rejection, 1-2 months following transplant. One was removed for pancreatitis and liver failure from operative complications. Late allograft enterectomies were generally for chronic rejection, some with residual acute rejection, but there were also a number of patients who had multiple superimposed conditions such as cytomegalovirus, Epstein-Barr virus, and post-transplant lymphoproliferative disorder in various combinations. One had idiopathic scarring and developed an adynamic bowel that remains unexplained. Examination of the resected specimens allows for dissection of the multiple contributions to graft failure, especially the vascular disease that can rarely be seen on mucosal biopsy. An unexpected finding was the impressive hypertrophy of neural elements, nerves, and ganglion cells in many of the patients, the significance of which requires further investigation.

Intestinal failure requiring total parenteral nutrition (TPN) is associated with significant morbidity and mortality. Intestinal transplantation can be a lifesaving option for patients with intestinal failure who develop serious TPN-related complications. The aim of this study was to evaluate survival, surgical technique, and patient care in patients treated with intestinal transplantation. We reviewed data collected from 95 consecutive intestinal transplants performed between December 1994 and November 2000 at the University of Miami. Fifty-four of the patients undergoing intestinal transplantation were children and 41 were adults. The series includes 49 male and 46 female patients. The causes of intestinal failure included mesenteric venous thrombosis (n = 12), necrotizing enterocolitis (n = 11), gastroschisis (n = 11), midgut volvulus (n = 9), desmoid tumor (n = 8), intestinal atresia (n = 6), trauma (n = 5), Hirschsprung's disease (n = 5), Crohn's disease (n = 5), intestinal pseudoobstruction (n = 4), and others (n = 19). The procedures performed included 27 isolated intestine transplants, 28 combined liver and intestine transplants, and 40 multivisceral transplants. Since 1998, we have been using daclizumab (Zenepax) for induction of immunosuppression and zoom videoendoscopy for graft surveillance. We began to use intense cytomegalovirus prophylaxis and systemic drainage of the portal vein. The 1-year patient survival rates for isolated intestinal, liver and intestinal, and multivisceral transplantations were 75%, 40%, and 48%, respectively. Since 1998, the 1-year patient and graft survival rates for isolated intestinal transplants have been 84% and 72%, respectively. The causes of death were as follows: sepsis after rejection (n = 14), respiratory failure (n = 8), sepsis (n = 6), multiple organ failure (n = 4), arterial graft infection (n = 3), aspergillosis (n = 2), post-transplantation lymphoproliferative disease (n = 2), intracranial hemorrhage (n = 2), and fungemia, chronic rejection, graft vs. host disease, necrotizing enterocolitis, pancreatitis, pulmonary embolism, and viral encephalitis (n = 1 case of each). Intestinal transplantation can be a lifesaving alternative for patients with intestinal failure. The prognosis after intestinal transplantation is better when it is performed before the onset of liver failure. Rejection monitoring with zoom videoendoscopy and new immunosuppressive therapy with sirolimus, daclizumab, and campath-1H have contributed to the improvement in patient survival.

An increased concentration of fibrin(ogen) degradation products (FDPs) commonly is used in conjunction with other hemostatic test abnormalities to identify patients with disseminated intravascular coagulation (DIC). Positive FDP results, however, have been observed in dogs without clinical evidence of DIC. The purpose of this study was to evaluate FDP concentrations in a group of clinically ill dogs with a variety of disorders. Dogs included in the study had the following hemostatic parameters evaluated: prothrombin time, activated partial thromboplastin time, fibrinogen concentration, platelet count, and FDP concentration. Two rapid latex agglutination methods were compared for detecting FDP in serum samples (Thrombo-Wellcotest, International Murex Technologies Corp) and plasma samples (FDP Plasma, American Bioproducts Inc). Results of the serum FDP method were positive in 8% (4/50) of the dogs tested: 3 with DIC and 1 with immune-mediated hemolytic anemia and liver disease. Results of the plasma FDP test were positive in 60% (30/50) of the animals tested: 6 with DIC, 3 with confirmed thrombosis, and 21 with a variety of conditions, including neoplasia, immune-mediated hemolytic anemia, pancreatitis, gastric dilatation-volvulus, heat stroke, severe trauma, sepsis, protein-losing nephropathy, liver disease, hyperadrenocorticism, and chronic heart failure. Because the plasma FDP test was positive more frequently than the serum FDP test in ill dogs, it may be more sensitive for the detection of canine FDP.

Radiography is a familiar and available imaging modality for the evaluation of patients with acute abdominal distress. Potential causes for acute abdominal distress include the hepatobiliary system, spleen, urogenital tract, and gastrointestinal tract. Radiographic signs associated with specific conditions are described, including gastric-dilation volvulus, urinary bladder rupture, ureteral rupture, urethral rupture, pancreatitis, and small intestinal obstruction. Additionally, contrast procedures that can be beneficial in evaluating the patient with acute abdomen, including positive contrast cystography, urethrography, excretory urography, and peritoneography, are described.

A 35-year-old female who had previously undergone an open gastric bypass, underwent elective caesarian section and ventral hernia repair, complicated by a double closed-loop obstruction with resulting gastric perforation. Back pain and anemetic nausea predominated, as proximal bowel and pancreatobiliary obstruction followed an afferent limb volvulus. Pancreatitis, cholangitis, and gastric perforation ensued, leading to intraabdominal sepsis. This rare situation must be recognized as a potentially serious complication of gastric bypass surgery, and requires prompt recognition and aggressive surgical correction.

Acute abdominal pain in children occurs often and requires rapid clarification. Hints as to the condition are often given by the first impression and the case history of the patient. When the clinical examination and laboratory results do not lead to a clear finding, imaging methods such as a sonography can clarify the case. The most common cause for abdominal pain in infants is acute enteritis, mostly brought about by rotaviruses. Additional diagnoses are abdominal hernia, malrotation, hypertrophic pyloric stenosis, invagination or gastroesophageal reflux. In school-age children, the classic finding is "appendicitis". This should be differentiated from constipation, gastritis, pancreatitis, sigmoid volvulus, bowel and intestinal obstruction or, perhaps, gallstone trouble.

Ascaris lumbricoides is one of the most common parasitic infestations of the gastrointestinal tract worldwide. During the intestinal phase of the disease, the adult worms usually remain clinically silent, sometimes causing a variety of non-specific abdominal symptoms. When present in large numbers, the worms may get intertwined into a bolus, causing intestinal obstruction, volvulus or even perforation. Occasionally, the adult Ascaris worm may migrate into the Vater's ampulla and enter the bile duct, gall bladder or pancreatic duct, leading to a variety of complications such as biliary colic, gallstone formation, cholecystitis, pyogenic cholangitis, liver abscess and pancreatitis. Imaging plays a significant role in showing the presence of worms and possible complications in intestinal as well as hepatobiliary ascariasis. This pictorial essay aims to illustrate various imaging features of ascariasis and its associated complications.

A rare case of an Ascaris worm emerging through an intercostal chest tube is reported here because of its unusual presentation. A five-year-old male child had a liver abscess, which had ruptured into the right pleural cavity. An intercostal chest tube was inserted for right pleural effusion. On the 5th postoperative day, a 7 cm long worm was noticed emerging through the chest tube. Ascaris lumbricoides infestation can lead to serious complications because of the mobility of the worms. Though complications such as intestinal obstruction, volvulus, gangrene, pancreatitis, biliary obstruction, cholangiohepatitis, and liver abscess have been reported to occur, intrapleural ascariasis is an extremely rare situation. This report describes a clinical situation of intrapleural ascariasis and emphasizes the importance of remaining aware of this rare complication of ascariasis.

A 65-year-old male was operated for esophageal carcinoma. Transhiatal esophagogastrectomy with jejunostomy feeding tube was done. Orals were started on the 12th postoperative day. The jejunostomy feeding tube was removed on the 20th postoperative day. Immediately after removal of the feeding tube, a 10-12 cm ascaris was seen emerging through the jejunostomy tract. Ascaris lumbricoides can cause a variety of complications like intestinal obstruction, perforation, biliary obstruction, pancreatitis, liver abscess, cholangiohepatitis, volvulus, and gangrene, etc. Although the above-mentioned complications have been frequently reported, ascaris exit through the feeding jejunostomy tract is very rare. This case is reported here to emphasize the importance of this complication of wandering ascariasis.

Acute abdomen can be defined as a medical emergency in which there is sudden and severe pain in abdomen with accompanying signs and symptoms that focus on an abdominal involvement. It accounts for about 8 % of all children attending the emergency department. The goal of emergency management is to identify and treat any life-threatening medical or surgical disease condition and relief from pain. In mild cases often the cause is gastritis or gastroenteritis, colic, constipation, pharyngo-tonsilitis, viral syndromes or acute febrile illnesses. The common surgical causes are malrotation and Volvulus (in early infancy), intussusception, acute appendicitis, and typhoid and ischemic enteritis with perforation. Lower lobe pneumonia, diabetic ketoacidosis and acute porphyria should be considered in patients with moderate-severe pain with little localizing findings in abdomen. The approach to management in ED should include, in order of priority, a rapid cardiopulmonary assessment to ensure hemodynamic stability, focused history and examination, surgical consult and radiologic examination to exclude life threatening surgical conditions, pain relief and specific diagnosis. In a sick patient the initial steps include rapid IV access and normal saline 20 ml/kg (in the presence of shock/hypovolemia), adequate analgesia, nothing per oral/IV fluids, Ryle's tube aspiration and surgical consultation. An ultrasound abdomen is the first investigation in almost all cases with moderate and severe pain with localizing abdominal findings. In patients with significant abdominal trauma or features of pancreatitis, a Contrast enhanced computerized tomography (CECT) abdomen will be a better initial modality. Continuous monitoring and repeated physical examinations should be done in all cases. Specific management varies according to the specific etiology.
