Background: Single-port laparoscopic surgery (SPLS) is increasingly used in surgery and in the treatment of perforated duodenal ulcer. The aim of this study was to evaluate technical factors for perforated duodenal ulcer repair by SPLS.
Methods: A prospective study on 42 consecutive patients diagnosed with perforated duodenal ulcer and treated with SPLS at Hue university of medicine and pharmacy hospital and Hue central hospital from January 2012 to February 2015.
Results: The mean age was 48.1 ± 14.2 (17 - 79) years. 40 patients were treated with suture of the perforation by pure SPLS. There was one case (2.4%) in which one additional trocar was required. Conversion to open surgery was necessary in one patient (2.4%) in which the perforation was situated on the posterior duodenal wall. Two patients (4.8%) with history of abdominal surgery were successfully treated by pure SPLS. The size of perforation was correlated with suturing time (correlation coefficient r = 0.459) and operative time (correlation coefficient r = 0.528). Considering suture type, X stitches were used in 95.5% cases, simple stitches were used in one case (2.4%) while Graham patch repair technique was utilized in one case (2.4%) with large perforation. Most cases (95.1%) required only simple suture without omental patch. Peritoneal drainage was spared in most cases (90.2%).
Conclusions: SPLS is a safe method for the treatment of perforated duodenal ulcer. Posterior duodenal location is the main cause of conversion to open surgery. Factor related to operative time is perforation size.
Key words: perforated duodenal ulcer, single port laparoscopic repair, single port laparoscopy
