OUTCOMES
DISCUSSION
• RETROSPECTIVE STUDIES, POSSIBLY HIGH LEVELS OF BIAS
• HETEROGENEITY BETWEEN STUDIES
• SURGEONS’ EXPERIENCE
• DIFFERENT METHODS OF LIGATION
• DIFFERENT PERIOPERATIVE ANTIBIOTIC REGIMENS
• SHORT FOLLOW-UP PERIODS (< 1 MONTH)
RECOMMENDATION
• LAPAROSCOPIC INTERVENTION IS SUPERIOR TO THE
OPEN PROCEDURE IN TERMS OF SECONDARY
OUTCOME MEASURES
• NO SIGNIFICANT DIFFERENCES IN IAA FORMATION
