Summary. Objective. Laparoscopic perforated duodenal ulcer repair is a minimally invasive technique. Just like any other type of surgery, the laparoscopic approach carries operative risks in itself. The primary goal of this article is to describe the possible risk factors in laparoscopic duodenal ulcer repair. The secondary goal is to clarify benefits of the laparoscopic surgery. Material and methods. The Medline/Pubmed database was used; 73 articles were analyzed and evaluated. Results. Six retrospective and nine prospective studies are summarized. The retrospective studies’ results are as follows: total complication rate is 728% (average 16%); conversion rate is 630% (average 18%); postoperative mortality rate is 020% (average 6%); and average hospital stay is 617 days (average 8 days). The results of the prospective studies are the following: total complication rate is lower 525% (average 11%); conversion rate is lower 027% (average 14%); postoperative mortality is lower 010% (average 3%); and average hospital stay is shorter 410 days (average 6 days). The difference is not significant but the results are better than in prospective studies. The risk factors were identical. Conclusions. Shock, delayed presentation (>24 hours), confounding medical condition, age >70 years, American Society of Anesthesiology IIIIV° and Boey score all above should be considered as preoperative laparoscopic repair risk factors. Inadequate ulcer localization, large perforation size (>6 mm diameter according to ones, >10 mm according to others) and ulcers with friable edges are also considered as laparoscopic repair risk factors: each of the factors independently is an indication for an open repair.
