Anaesthetic management of laparoscopic pyloromyotomy for infantile hypertrophic pyloric stenosis: A retrospective study of 109 cases

Anaesthesia for laparoscopic pyloromyotomy poses multiple challenges. We have analysed our experience of anaesthetizing these infants by describing the perioperative events statistically in order to improve our anaesthetic technique. Pre-operative records, demographic details, intraoperative and post operative records of all cases of laparoscopic pyloromyotomy performed over a period of 5 years in a tertiary care unit were collected and reviewed. A statistical analysis of demographic details, preoperative clinical features with emphasis on metabolic derangements, adverse events during surgery and in the post operative period was done. We observed a combined intraoperative and post operative complication rate of 20% with no occurrence of mortality. Maximum morbidity post operatively was due to the development of emesis seen in 8 children (7.3%).
