A hepaticojejunostomy: technical errors with 'twists and turns'.

Excision of a choledochal cyst followed by biliary reconstruction with a Roux-en-Y hepaticojejunostomy is the treatment of choice for type I and IV choledochal cysts. We present a rare complication which was identified 8 years after the original reconstructive surgery. Conventional imaging modalities failed to identify the pathology. Only a contrast enhanced CT scan supported by image rendering software allowed for the visualization of the underlying chronic obstruction of part of the mesentery.

Malrotation volvulus in a neonate: a novel surgical approach.

A newborn presented with bilious vomiting secondary to a malrotation and presumed perinatal-onset volvulus. Laparotomy was performed at 20 h of age at which the volvulus was derotated. Nevertheless the small but not the large bowel appeared to be completely ischaemic and non-viable. A second-look laparotomy was performed 24 h later with no significant improvement. In a new approach to the problem, nothing further was done and the child was left alone on parenteral nutrition and naso-gastric aspiration for 11 weeks. Further exploration showed that 40 cm of small bowel had survived intact and restorative surgery was carried out. Parenteral nutrition was discontinued after 9 months and the child, now aged 3.5 years, is thriving.

Segmental infarction of the omentum: a difficult diagnosis.

Segmental infarction of the greater omentum is a rare diagnosis. This report describes a case of omental torsion in an eight-year-old boy. The report assesses the predisposing factors, the classification and the place of ultrasonography.

Outcome analysis of pyeloplasty in infants.

The study examined the outcome of pyeloplasties done for decompensated ureteropelvic junction (UPJ) obstruction in infancy over a 13-year period. In a retrospective study, 186 children who underwent pyeloplasty in infancy were analysed with particular emphasis on the pre- and postoperative findings of 123I hippuran scintigraphy/diuretic renograms. The pre- and postoperative management is outlined in detail. The 186 patients underwent a total of 203 pyeloplasties during the period from January 1983 to 31 December 1996. Three children died; one required a nephrectomy. The postoperative scintigrapic results of 156 children (85%) done about 12 months after surgery were available for evaluation: 101 (64%) showed stable renal function and 43 (27%) revealed more than 5% improvement of renal function. In 12 cases (7%) renal function deteriorated after pyeloplasty by more than 5% compared to the preoperative scintigram. It is concluded that pyeloplasty in infants is a low-risk procedure. The encouraging results of this series support early correction of UPJ obstruction.

Diagnosing hypertrophic pyloric stenosis: does size matter?

This retrospective study examines the size of the pyloric tumour at the time of surgery in 100 patients (76 boys, 24 girls) operated over a 2.75 years period from June 1993 to March 1996. The size of the pyloric tumour was classified into one of three categories (short, moderate or large) by the operating consultant and documented in the operation note. This study supports the view that the pyloric tumour increases in size with the progressing age of a baby. Nowadays the diagnosis of hypertrophic pyloric stenosis (HPS) is made on average 2 weeks earlier than in a similar study 4 decades ago. Two thirds of the patients in the subgroup with short- and moderate-size pyloric tumours did not require any imaging technique to arrive at the diagnosis. Unexpectedly a more frequent use of imaging techniques was required in the subgroup of large pyloric tumours; large tumours tend to present as an ill-defined fullness in the right upper quadrant rather than a distinct olive.

Congenital hypertrophic pyloric stenosis with associated polyhydramnios in a premature infant.

Congenital pyloric stenosis is rare in premature infants. This is a report of pyloric stenosis in a premature infant (35 weeks gestation) discovered on the 2nd day of life. There appears to be an association with polyhydramnios. Congenital hypertrophic pyloric stenosis should be considered in the differential diagnosis of premature infants with upper gastrointestinal symptoms. A review of the literature is included.
