AbstractThere is increasing awareness of the value of day case paediatric surgery in fulfilling the needs of the community. Is this cost effective, are there hidden complications and is there a need for routine follow-up? Seven hundred and thirty-one children attending the Red Cross War Memorial Children's Hospital day surgery unit over a 32-month period, and undergoing 912 procedures confined to the inguinoscrotal region, were enrolled in the study. Surgical procedures performed included inguinal herniotomy, orchidopexy and circumcision. Of the 731 children, 159 consecutive children had their inguinal and perineal skin flora analysed preoperatively and in 59 of these children three skin swabs were taken from the groin area: before routine skin preparation for surgery, after the skin preparation and on completion of the operation. Staphylococcus epidermidis predominated as the normal skin flora (70%), followed by Escherichia coli (19%) and Proteus mirabilis (10%), while S. aureus was only found in 2.5% of cases. The efficacy of cleaning with 4% chlorhexidine and 2% povidone-iodine in 70% alcohol is shown by virtual complete eradication of the organisms isolated from the preoperative skin cultures. In only 2 cases (3.4%) were organisms (S. aureus and S. epidermidis respectively) isolated following skin preparation. Cultures taken at the end of operative procedures grew predominantly S. epidermidis (5 cases, 8.5%). Children were discharged from the day unit once they had taken fluids and had passed urine. The wounds were also checked for any evidence of bleeding. Follow-up was done 2 weeks later by means of a visit to the day unit where the same surgeon assessed wound healing according to the Southampton Wound Assessment Scale. Ninety-four per cent of the wounds had healed by primary intention; 4.5% had minor complications and 1.5% had septic complications. Our trial confirms that wound sepsis is an infrequent but significant complication of day case groin surgery. Routine follow-up by surgical day units of minor surgical cases is not warranted and will incur unnecessary cost. Only 1.5% of postoperative cases will require further medical attention and septic lesions in the lymphatic drainage area should be regarded as risk factors.
