We analyzed clinical, biochemical, and histo- logic parameters of ten infants with parenteral nutrition-induced hepatobiliary dysfunction. The data were compared with the results of a rabbit model. All infants were born prematurely with low birth weight. Their clinical diagnoses were necrotizing enterocolitis (6), gastroschisis (1), intrauterine volvulus (1), and lung hypoplasia (2). All required total (TPN) or partial parenteral nutrition for at least 8 weeks. All had repeated episodes of infections or sepsis. A rise in bilirubin and aminotransferase levels occurred after a minimum of 5 weeks; peak bilirubin levels ranged from 4 to 14 mg% and aminotransferases from 40 to 140 IU/l. One child later developed gallstones. Liver biopsies after 1 to 24 months showed fibrosis, bile-duct proliferation, cholestasis, and hydropic degeneration. All of the above-mentioned clinical factors have been accused of causing the observed biochemical and histologic changes. In our rabbit model we were able to produce almost identical symptoms by TPN alone: gallbladder distension, sludge, and stones developed after 1-4 weeks of TPN as well as uncharacteristic changes in aminotransferases and bilirubin after 4 weeks. Liver histology revealed severe hydropic degeneration of zone 3 as early as 1 week after beginning TPN. A rise of fibrosis and bile-duct proliferation after 1 to 4 weeks of infusion was statistically significant. Cholestasis, as was observed in the infants, could not be detected. In our model, all alterations observed could be attributed exclusively to TPN. We therefore assume that TPN was the true cause of the dysfunction. In a second experimental series infusions were reduced to 80% PN and free access to lab chow. These animals produced normal feces, indicating physiologic enteral stimulation. They developed the same degenerative and proliferative histologic changes, whereas gallbladder distension, sludge, and stones were not noted. We conclude that: (1) The TPN solution itself is responsible for the histologic changes in the liver, which is supported by the fact that hydropic degeneration of zone 3 is typical of a direct toxic effect; and (2) Complete enteral starvation with an absence of enteral stimulation causes disease of the lower biliary tract.

The survival of infants with major abdominal-wall defects (AWD) has improved over the years in developed countries. In Zaria, northern Nigeria, survival from intact exomphalos (EX), has improved with the adoption of non-operative management. Ruptured EX (REX) and gastroschisis (GS), however, remain problematic. This is a report of the mortality in REX and GS in a retrospective review of 16 infants with REX and 14 with GS managed over 10 years at the Ahmadu Bello University Teaching Hospital, Zaria. The median age at presentation was 3 days and 24 h for REX and GS, respectively; 29 of the 30 patients were delivered at home. Two patients with REX and 4 with GS had associated anomalies involving mostly the gastrointestinal tract. Bowel or omental strangulation occurred in 13 patients, resulting in gangrene in 8. Fascial closure was achieved in 20 patients, skin closure only in 4, and in 4 improvised silo coverage was used, the latter associated with high infection rate. Neonatal intensive care units (NICU) and total parenteral nutrition (TPN) were not available. The overall mortality was 18.6% (gastroschisis 10, ruptured exomphalos 8, 11 from sepsis and 7 due to respiratory embarrassment). The management of these AWDs thus continues to be problematic in our environment, and mortality remains high. Provision of more modern supportive facilities (NICU and TPN) may improve the survival in our and similar environments.

The intrauterine surgical placement of vesicoamniotic shunts in the treatment of fetal obstructive uropathy associated with prune-belly syndrome to avoid such complications as renal damage and oligohydramnios remains controversial. We present a case of an infant born with prune-belly syndrome at 33 weeks and 5 days of estimated gestational age to a mother of two by vaginal delivery after a pregnancy complicated by fetal obstructive uropathy with attempted intrauterine intervention. After sonographic and laboratory diagnostic and prognostic evaluations, an intrauterine procedure was performed in which a vesicoamniotic shunt was placed under ultrasound guidance. Complications included dislodgment of the initial shunt, with a failed subsequent attempt at placement, oligohydramnios, preterm labor and delivery, and traumatic gastroschisis through the surgical abdominal wall defect. His hospital stay was further complicated by chronic renal insufficiency, prematurity, respiratory distress, bowel malrotation, an episode of gram-negative sepsis with Enterobacter cloacae, signs of liver failure, an exploratory laparotomy for severe enterocolitis, and orchiopexy for bilateral undescended testes. At present, it is unclear whether vesicoamniotic shunt placement can provide any significant improvement in the morbidity or mortality for patients with prune-belly syndrome. A large, prospective, randomized trial is needed to determine its efficacy.

The survival rate of patients with abdominal wall defects has gradually improved with the advances in the investigation and treatment modalities. The present paper reviews the results of various treatment modalities and also analyses the long term results in these patients. A meta-analysis was performed via a medline search of English written clinical studies containing the text words "abdominal wall defects", gastroschisis and 'omphalocele or exomphalos" from 1953 to 1998. The present consensus on operative management of abdominal wall defect is to provide primary closure, if it can be achieved without haemodynamic or respiratory compromise. Patients with primary closure on analysis were found to have better survival rates, reduced risk of sepsis and overall, a shorter hospital stay. However, resumptions of oral feeds, duration of total parenteral nutrition (usually lasting 10-15 days) and ventilatory support required postoperatively did not significantly differ in the primary and silo technique. Long term outcome of these patients is generally good, but they have high incidence of GER (40-50%) for which they should be on regular follow up.

The aim of the study was the definition of standard approach to a newborn with gastroschisis. The rules of treatment introduced in 1992 enabled the closure of the abdominal wall primarily in all newborns and made it possible to decrease the mortality considerably. This was achieved despite the fact that we usually did not have influence on time and method of delivery or quality of transportation to our department. In the Department of Pediatric Surgery of Institute Mother and Child, in the years 1992-1997, twenty three newborns with gastroschisis were admitted. The standard approach in all patients was the following: insertion of the catheters to the small bowel through the appenddicocaecostomy and to the large bowel through the rectum, intraoperative irrigation of the meconium (mucosolvan), forceful stretching of the abdominal wall, returning of extraabdominal viscera under control of central venous pressure or middle airway pressure (anesthesiologic control). In the postoperative period all patients routinely had controlled ventilation, administration of analgesic drugs, catecholamines, antibiotics and total parenteral nutrition. Intestinal catheters were gradually removed every day for irrigations of all levels. Oral nutrition was started after the return of effective peristalsis. From 23 treated newborns 16 are alive. 7 children died, 4 of them were resuscitated before operation because of severe general condition. Two patients died because of sepsis in the second month of life, one because of SIDS (sudden infant death syndrome) in the third week of life. Sixteen children are followed up. The development of all children is normal.

Between 1990 and 1999, 14 neonates with intestinal perforation were treated at the Ahmadu Bello University Teaching Hospital, Zaria, Nigeria. Median age at presentation was 9 days and median weight 2.65 kg. Five had high anorectal malformation, three Hirschsprung's disease and two ruptured exomphalos with bowel strangulation. Gastroschisis, strangulated inguinal hernia, ileal atresia and umbilical sepsis with evisceration accounted for one case each. Two of the perforations were iatrogenic during colostomy construction. Seven perforations were in the small bowel and seven in the colorectum. Three neonates had oedema and tenderness of the anterior abdominal wall, and pneumoperitoneum was seen in abdominal radiographs in two. All the infants had laparotomy, four under local anaesthesia, after resuscitation. Three had simple suture of the perforation, five had resection with primary anastomosis and six had exteriorization colostomy. Overall, eight (59%) died, five with colorectal perforation and three with small bowel perforation.

Pediococci are recently recognized Gram-positive human pathogens, resistant to vancomycin and generally susceptible to penicillin. Infection in adults has been seen in patients with chronic underlying conditions as well as those with previous abdominal surgery. Two previous infants with congenital gastrointestinal malformations requiring surgical correction have been reported with sepsis attributable to Pediococcus sp. We report a third infant born with gastroschisis who developed Pediococcus bacteremia and meningitis 3 months after surgery, and speculate regarding the role of probiotics in the pathogenesis of this infection.

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.

The aim of this study was to evaluate contemporary patterns of presentation and trends in the management and outcome of newborn infants with jejuno-ileal atresia at a regional paediatric surgical centre in the United Kingdom. The hospital neonatal surgical registry was used to identify patients with jejuno-ileal atresia (n = 83) admitted between 1976 - 1998, excluding those associated with gastroschisis. The clinical records were reviewed and antenatal information, patient demographics, associated anomalies, operative treatment, post-operative management and outcomes were analysed in three time periods to identify trends in management and survival: Group 1 1976 - 1982 (n = 32), Group 2 1983 - 1990 (n = 21), and Group 3 1991 - 1998 (n = 30). Overall survival was 90 %. The number of patients with associated anomalies were Group 1, 10 (31 %); Group 2, 7 (33 %); and Group 3, 11 (37 %). Cystic fibrosis was encountered in 4 (13 %), 1 (5 %) and 4 (13 %) patients, respectively. Resection with primary anastomosis was the definitive management in most of patients: Group 1, 25 (78 %); Group 2, 17 (81 %); and Group 3, 27 (90 %). Initial stoma followed by delayed primary anastomosis was performed in 14 infants; eight patients had divided stomas while 6 had Bishop-Koop stoma. Tapering was used in 10 patients (12 %) with proximal jejuno-ileal atresia. Parenteral nutrition was increasingly utilised over the three time periods studied. There were no deaths in Group 3 compared to 6 deaths in Group 1 and 2 in Group 2 (P = 0.02). Most of the deaths were due to overwhelming sepsis. Mortality did not correlate significantly with the TYPE of atresia, presence of associated anomalies or the need for long-term total parenteral nutrition. The overall complication rate in survivors was 18 %. In the infants undergoing Bishop-Koop operation the complication rate was 50 %. This study has shown a significant reduction in mortality from jejuno-ileal atresia, which may be attributed primarily to advances in perioperative management, including parenteral nutrition. Generous resection of the atretic segment with primary anastomosis is more frequently employed in preference to initial stoma formation. Cystic fibrosis remains an important co-morbid condition that must be excluded promptly in all newborns.

This retrospective study elicits information regarding the dependence of neonatal outcome in gastroschisis upon: (1) the mode of delivery, (2) place of birth, (3) time for birth to surgery, (4) method of closure, (5) time from operation to commencement of first enteral feeds. The neonatal intensive care database from five major tertiary centres was used to identify 181 neonates with gastroschisis from 1990 to 2000. There were 8 deaths. There were no significant differences in outcome for infants delivered vaginally (102) versus Caesarean section (79), those born near the tertiary centre (133) as compared to infants born away (48), ones operated within 7 hours (125) compared with those operated after 7 hours (56), with delayed closure (30) versus primary closure (151). Neonates fed within 10 days of operation (85) had significantly lower incidence of sepsis, duration of TPN and hospital stay when compared to those fed after 10 days (96). Early commencement of feeds decreases the incidence of sepsis, duration of total parenteral nutrition (TPN) and hospital stay. Place of delivery, mode of delivery, time to surgery and type of closure do not influence neonatal outcome.
