Scrotal fixation in the management of low undescended testes.

Aims: Scrotal fixation (SF) is a known technique for the management of low undescended testes (UDT). SF assumes that most low UDT have no patent processus vaginalis (PPV) and can be managed via scrotal mobilization alone. We report our experience of the role of SF in the management of low UDT.

Validity of 13C octanoic acid breath test for measurement of solid meal gastric emptying time in children.

Background/purpose: It is important to establish a physiologic range of gastric emptying (GE) in children. Gastric emptying time measured with (99)Tc-labeled solid meal (GE(Tc)) is the gold standard. Large-scale studies with GE(Tc) are ideal but not feasible because of radiation exposure.

Gastric emptying of solids in normal children--a preliminary report.

Objective: The physiological range of gastric emptying in healthy children has not previously been documented. The aim of this study was to establish the range of normal gastric emptying in children aged between 5 and 10 years with a Tc 99m-labelled solid meal acceptable to most of the children.

Methods: A list of 7 child-friendly foods was compiled.

Use of pelvic ultrasound in the diagnosis of megarectum in children with constipation.

Purpose: It has not been possible so far to differentiate slow transit constipation from functional fecal retention because the existing medical literature lacks data on rectal dimensions for healthy children or children with chronic idiopathic constipation (CIC). We, for the first time, describe the use of pelvic ultrasound (US) to achieve this.

Methods: A pelvic US was carried out on 82 children with a full or partially full bladder and with no history of bowel problems and on 95 children with CIC.

Denis Browne's thoracotomy revised.

The three main issues involved in thoracotomy technique for the repair of oesophageal atresia (OA) are: (1) prevention of chest wall deformities; (2) adequate surgical exposure; and (3) the cosmetic appearance of the skin scar. Adequate surgical exposure should be the first priority. The technique described is an endeavour to address all the above concerns, a modification of the technique described by Denis Browne that eliminates the risk of injury to the long thoracic nerve (LTN).
