Since June 1990, five girls and one boy have been evaluated for biliary colic. Gallstones were documented by sonography. Two girls, ages 8 and 14 years, had hereditary spherocytosis, and a 9-year-old boy had sickle cell disease. The other three girls, ages 13, 13, and 15 years, developed cholelithiasis and biliary colic without a history of hematological disease. Three children weighed less than 90 lb, with the smallest weighing 45 lb. All patients underwent laparoscopic cholecystectomy without complications. Operative cholangiography was performed in five of the six children. The KTP-532 laser was used for dissection of the gallbladder from the liver bed in two patients, and electrocautery was used in the remaining four. The average operating time was 1 hour 45 minutes. This is a report of the use of laparoscopic cholecystectomy in pediatric patients. The advantages of its use include a shorter hospitalization, decreased postoperative discomfort, and a much shorter interval between the surgical procedure and return to normal activities such as school and play. At this time, it is recommended for those children without complications from their cholelithiasis such as common duct obstruction and gallstone pancreatitis.

Pancreatitis in children is not common but can be associated with severe morbidity rates. We have treated 49 children with pancreatitis over the past 12 years ranging in age from 1 month to 18 years. One third of the patients had biliary tract disease as an etiology, with nearly half of these being related to underlying hematologic disease, usually sickle cell anemia. Another third of the pancreatitis was due to trauma, and one third of these were related to child abuse. Other etiologies were systemic disease (6 patients), congenital anomalies (8 patients), and idiopathic (3 cases). Eighty-two per cent of the patients presented with abdominal pain, but four children, all less than 4 years old, presented with an abdominal mass. Twenty-nine patients required 33 operations for pancreatitis. Fifteen of the 16 patients with biliary tract disease and all patients with congenital anomalies required operation. Six of the 16 patients with trauma required operation and none of those with systemic disease. As in adults ultrasonographic examination and CT scan are most important in the diagnosis; medical treatment consists of intravenous (I.V.) fluids, nasogastric suction, and total parenteral nutrition (TPN), and risk factors can help predict the severity of the disease while amylase alone is not related to severity. Different from adults, in children an etiology can usually be determined. The common etiologies, biliary tract disease, trauma, and congenital anomalies frequently require operation.

A case of pancreatitis that occurred as a complication of a vaso-occlusive crisis in a child with sickle cell anemia is reported. We encourage others to consider pancreatitis as a cause for abdominal pain in children with multisystem diseases, particularly those that may cause ischemic organ injury such as sickle cell anemia.

Osteonecrosis is a clinical entity characterized by death of bone marrow and trabecular bone as a result of disruption of blood supply to the bone (1,2). Other aspects of this condition include avascular necrosis, aseptic necrosis, and osseous ischemic necrosis of bones. Osteonecrosis is classified into two main forms; post-traumatic and nontraumatic. The post-traumatic form of osteonecrosis usually develops as a result of traumatic displacement of bone fragments, which leads to impaired blood supply and ischemia to the affected bone. Osteonecrosis of the femoral head is common following fracture of the femoral neck. A variety of systemic diseases and clinical conditions are associated with nontraumatic osteonecrosis. These include autoimmune rheumatic diseases, alcoholism, pregnancy, Gaucher's disease, thrombophilia, corticosteroid therapy, Sickle-cell anemia, pancreatitis, inflammatory bowel diseases, and use of cytotoxic drugs and others. Idiopathic forms of osteonecrosis have also been reported (2-4). Among the rheumatic diseases, osteonecrosis is strongly associated with systemic lupus erythematosus (SLE) (5). However, osteonecrosis has been diagnosed in patients with primary antiphospholipid syndrome (APS) (6), rheumatoid arthritis (7), and systemic vasculitis (8). This article reviews the causes, clinical and epidemiological features, diagnosis, and treatment options for osteonecrosis among patients with SLE.

All patients undergoing endoscopic retrograde cholangiopancreatography (ERCP) at the University Hospital of the West Indies (UHWI) were entered into a prospective database. Parameters included demographics, indication for the procedure, success of the ERCP and any immediate complications noted. Retrospectively, the patients' case notes were analyzed for complications developing after 24 hours, and outcome. During the period March 1999 to December 2002, a total of 120 consecutive patients were subjected to 123 ERCPs, all being performed by a single gastroenterologist. Of these 120 patients, eight had ERCP as outpatients and were transferred back to their referring hospitals. These patients were excluded from further analysis. Of the 115 UHWI patients, the case notes of 96 were available for analysis and this group formed the basis of this review. ERCP had successful cannulation in 95% of patients. There were 70 females and 26 males with a female to male ratio of 2.7:1. Age ranged from 13 to 85 years (mean +/- SD, 43 +/- 17), males being an average six years older than females. The most common indication for ERCP was a patient with cholelithiasis and abnormal liver function tests scheduled for laparoscopic cholecystectomy. This made up 33% of patients and in this subgroup, sickle cell disease accounted for 50% of cases. Patients with common bile duct stones preoperatively and post-cholecystectomy accounted for 13% and 17% respectively while gallstones pancreatitis accounted for 13% of cases, including three patients with severe pancreatitis. While 64% of the patients had normal cholangiogram, 66% of them had sphincterotomy. Common bile duct stones were seen in 23 cases and complete removal was successful in 48%. There were ten cases (10%) of ERCP pancreatitis and this was severe in three patients and the direct cause of death in one. One patient had ascending cholangitis post ERCP and there were no cases of post-sphincterotomy bleeding or duodenal perforation. Endoscopic retrograde cholangiopancreatography at the UHWI has high diagnostic yield but its therapeutic use needs further development.

The role and value of endoscopic retrograde cholangiopancreatography (ERCP) in the pediatric age group is not well established, because pancreatic and biliary diseases are less common in children. This however is not the case in areas like the Eastern Province of Saudi Arabia where sickle cell disease (SCD) and other hemoglobinopathies are common, with increased frequency of cholelithiasis and choledocholithiasis. The purpose of this study was to evaluate the indications, findings, safety and therapies of ERCP in children. One hundred and twenty five children had diagnostic and/or therapeutic ERCP as part of their management at our hospital. Their medical records were reviewed for: age at diagnosis, sex, Hb electrophoresis, indication for ERCP, findings, therapy and complications. There were 77 males and 48 females. Their age at presentation ranged from 5-18 year (mean 13.25 year). The majority of them had sickle cell disease (77.6%). The indications for ERCP were: obstructive jaundice (67.2%), recurrent biliary colic with or without jaundice (10.4%), acute and chronic pancreatitis (7.2%), postoperative bile leak (2.4%), cholangitis with obstructive jaundice (2.4%), hepatitis of unknown etiology (3.2%), cirrhosis of unknown etiology (4%), thalassemia with jaundice (0.8%), hemobilia (0.8%), acute cholecystitis with jaundice (0.8%), and sickle cell disease with ulcerative colitis and obstructive jaundice (0.8%). In six children, ERCP was done following laparoscopic cholecystectomy. ERCP was carried out under sedation in 91 (72.8%) children and under general anesthesia in 34. It was successful in 121 (96.8%) children while cannulation of the Ampulla failed in four. ERCP was normal in 43 children, but eight of them showed evidence of recent stone passage and in six, there were gallstones. In the remaining children, ERCP revealed: normal CBD with stones (18 patients), dilated CBD with stones (17 patients), dilated CBD without stones (19 patients), dilated biliary tree with stones (10 patients), dilated biliary tree without stones (six patients), bile leak (two patients), dilated biliary tree with stones and choledocho-duodenal fistula (one patient), choledochal cyst (two patients), septate gallbladder (one patient), normal ERCP with multiple pancreatic cysts (one patient) and biliary stricture (one patient). The following procedures were carried out: 35 had endoscopic sphincterotomy and stone extraction, 20 had endoscopic sphincterotomy, four had CBD stenting, one underwent removal of a stent, two had insertion of a nasobiliary tube and one had biliary endoprosethesis. There was no mortality. One had bleeding from the site of sphincterotomy which stopped after adrenaline injection. Four patients (3.2%) developed transient mild pancreatitis which settled conservatively. ERCP in the pediatric age group is safe both as a diagnostic and therapeutic procedure. ERCP can provide valuable information which aid in the diagnosis of biliary and pancreatic diseases in children as well as therapy with the technical feasibility of endoscopic sphincterotomy. This is specially so in the era of laparoscopic cholecystectomy, where ERCP should be the treatment of choice in children with CBD stones who are going or have previously undergone laparoscopic cholecystectomy.

Most asymptomatic gallstone carriers require no therapy. Laparoscopic cholecystectomy is the best definitive therapy for symptomatic gallstone disease. Selective laparoscopic cholecystectomy can provide secondary prevention of symptoms and complications in certain instances (in a complex clinical setting such as sickle cell disease or to prevent gallbladder carcinoma from developing in those at risk with large gallstones or with a calcified gallbladder). Primary prevention is unproven but focuses on early identification and risk alteration to decrease the possibility of developing gallstones. Ursodeoxycholic acid has a limited role for stone dissolution but can prevent stone development in severe obesity during rapid weight reduction with diet or after bariatric surgery. Endoscopic retrograde cholangiopancreatography with endoscopic sphincterotomy represents the therapeutic cornerstone for managing severe pancreatitis and cholangitis.

Choledocholithiasis can be caused by either primary or secondary bile duct stones. Although patients with sickle cell disease (SCD) are at high risk of development of pigmented gallstones due to chronic hemolysis, primary choledocholithiasis in SCD is very uncommon. The delay in the diagnosis of biliary tract pathology can occur in patients who had a prior cholecystectomy. There is a possible relationship between prior cholecystectomy and the subsequent occurrence of primary common bile duct stones, due to the higher probability of infection of the biliary system. Here, we report an unusual and severe case of multiple primary choledocholithiasis, associated with pancreatitis, in a patient with SCD, fourteen years after cholecystectomy.

Cell-free hemoglobin (Hb) has been blamed for a spectrum of problems, including vasoconstriction pancreatitis, myocardial infarction, and pulmonary hypertension in hemolytic anemia, malaria, and sickle cell anemia, and from Hb-based oxygen carriers (HBOCs). Toxicities have been attributed to scavenging of nitric oxide (NO). However, while NO scavenging may explain many in vitro effects, and some effects in animal models and clinical trials with HBOCs, key inconsistencies in the theory require alternative explanations. This review considers the hypothesis that cell-free Hb oversupplies oxygen to tissues, leading to oxygen-related toxicity, possibly through formation of reactive oxygen species and local destruction of NO. Evidence for this hypothesis comes from various sources, establishing that tissue oxygen levels are maintained over very narrow (and low) levels, even at high oxygen consumption. Tissue is normally protected from excessive oxygen by its extremely low solubility in plasma, but introduction of cell-free Hb, even at low concentration, greatly augments oxygen supply, engaging protective mechanisms that include vasoconstriction and ischemia. The requirement to limit oxygen supply by cell-free Hb suggests novel ways to modify it to overcome vasoconstriction, independent of the intrinsic reaction of Hb with NO. This control is essential to the design of a safe and effective cell-free HBOC.

Avascular necrosis of the femoral head (AVN) is an increasingly common cause of musculoskeletal disability, and it poses a major diagnostic and therapeutic challenge. Although patients are initially asymptomatic, AVN usually progresses to joint destruction, requiring total hip replacement, usually before the fifth decade. Avascular necrosis is characterized by osseous cell death due to vascular compromise. Avascular necrosis of bone results generally from corticosteroid use, trauma, pancreatitis, alcoholism, radiation, sickle cell disease, infiltrative diseases (e.g. Gaucher's disease), and Caisson disease. The most commonly affected site is the femoral head and patients usually present with hip and referred knee pain. The aim of diagnostic imaging procedures in avascular femoral head necrosis is to provide the patient with a stage-adapted therapy. Therefore, a differentiated diagnostic work-up is needed. Native radiography of the hip in two planes is still the first step. Over the past years, the diagnosis of femoral head necrosis has experienced tremendous improvement due to the use of MRI and CT scans. Because of these improvements the correct stage can be diagnosed early and the appropriate therapy can be initiated immediately. Today, MRI is the most sensitive diagnostic imaging procedure. CT scans can be particularly useful to exclude subchondral fractures. The use of bone scintigraphy is restricted to exceptional cases. In Europe, the ARCO classification of avascular femoral head necrosis has been widely accepted. In this overview, we describe the specific characteristics of the different diagnostic imaging procedures and illustrate them with appropriate imaging material.
