OBJECTIVE: To institute and validate the Global Assessment of Laparoscopic Surgery score as a measure of intraoperative performance. METHODS: The observational study was conducted at the Services Hospital, Lahore, and the National Hospital and Medical Centre, Lahore, from August 1, 2013, to February 28, 2014, and comprised Residents, Senior Registrars and Consultants who were divided into 3 groups.

SPSS 20 was used for statistical analysis. RESULTS: Of the 24 subjects in the study, 12(50%) were Residents, 6(25%) Senior Registrars and 6(25%) Consultants. The mean score for Junior group was 7.64±0.988, for Intermediate group 16.25±2.602 and for Senior group 22.83±1.169The score was highly reliable with intra-class coefficient 0.96, and internal consistency was excellent with Cronbach's Alpha 0.981. CONCLUSIONS: Global Assessment of Laparoscopic Surgery was found to be a valid and reliable measure of intraoperative laparoscopic skills.
