MID-TERM OUTCOME OF PERFORATED DUODENAL ULCER REPAIR USING SINGLE-PORT LAPAROSCOPIC SURGERY

Abstract

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 mid-term outcome of perforated duodenal ulcer repair using SPLS. Methods: A prospective study on 72 consecutive patients diagnosed with perforated duodenal ulcer and treated with SPLS at Hue University Hospital and Hue Central Hospital from January 2012 to Mars 2016. Results: The mean age was 48.8 ± 14.0 (17 - 79) years. Male/female ratio was 17.0. Four patients (5.6%) with history of abdominal surgery were successfully treated by pure SPLS. Patients were classified as ASA 1, ASA 2 and ASA 3 in 86.1%, 12.5%, and 1.4% of cases, respectively. Using Boey scoring system, there were 86.1% and 12.5% of cases classified as Boey 0 and Boey 1 while there were no Boey 2 and 3 cases. The average size of perforation was 4.1 ± 2.6 (1.5-22) mm. The perforation was situated on the anterior duodenal wall in 98.6% of cases and on the posterior duodenal wall in 1.4% of cases. There was one case (1.4%) in which one additional trocar was required. Conversion to open surgery was necessary in one patient (1.4%) in which the perforation was situated on the posterior duodenal wall. Average length of hospital stay was 5.7 ± 1.2 (4-12) days. Post-operative complications rate was 2.8%. There was no leakage from the repair site, no port-site hernia and no post-operative mortality. At 2-month follow-up visit, patients were classified as Visick 1 in 95.1% of cases and Visick 2 in 4.9% of cases and the duodenal ulcer was completely healed on gastroduodenoscopy in 86.7% of cases. At 12-month follow-up, patients were classified as Visick 1 in 93.5% of cases and Visick 2 in 4.3% of cases. There was one case (2.2%)diagnosed with recurrent duodenal ulcer perforation at 5 months after the repair of the first perforation. On gastroduodenoscopy, recurrent duodenal ulcer was seen in 8.9% of cases. Conclusions: SPLS is a safe method for the treatment of perforated duodenal ulcer. Conversion rate was 1.4%. Recurrent duodenal ulcer rate was 8,9% and recurrent duodenal ulcer perforation rate was 2.2% after 12-month follow-up.
