Aim. To estimate the frequency of ulcerative bleeding, pyloric stenosis, need for pyloroplasty and the justification of vagotomy for perforated duodenal ulcer.Materials and Methods. We analyzed the surgical treatment of patients with perforated duodenal ulcer admitted to Podgorbunskiy Regional Clinical Emergency Hospital during 1999-2019.Results. In 2018, the number of surgical interventions due to perforated duodenal ulcer decreased by 56.4% in comparison with 1998. In 8.6% and 2.1% of patients, perforated duodenal ulcer was combined with pyloric stenosis and bleeding, respectively, requiring Judd pyloroplasty (diamond- shaped transverse excision) or gastroduodenotomy followed by Heineke-Mikulicz pyloroplasty (transversely closed longitudinal incision across the pylorus) and vagotomy. Distal gastric resection by Billroth’s operation II was required in 2.8% of patients. Repeated admission of patients with duodenal ulcer complications has been observed after isolated suturing of perforated duodenal ulcer.Conclusion. Over the last 20 years, the amount of surgical interventions because of perforated duodenal ulcer in Kemerovo Region decreased more than twofold. In > 10% patients, pyloric stenosis and bleeding require a gastric drainage. In > 8% patients, perforated duodenal ulcer is combined with pyloric stenosis; in these cases, Heineke-Mikulicz pyloroplasty may be a treatment of choice. In > 2% patients, perforated duodenal ulcer is combined with ulcerative bleeding requiring excision of the ulcer and optional distal gastric resection. Pyloroplasty may be combined with vagotomy to normalise the proteolytic activity of gastric acid.
