Stapfer I and II duodenal perforations after endoscopic procedures: how surgical delay impacts outcomes

Post-endoscopic duodenal perforation is a severe adverse event with high morbidity and mortality rates. Managing this rare event is challenging owing to limited clear guidelines. This retrospective study aimed to examine the relationship between time-to-treatment and morbidity among patients with post-endoscopic duodenal perforations.

Over 20 years, 78 consecutive patients with post-endoscopic duodenal perforations were analyzed. Among these, most patients underwent endoscopic procedures at the Paoli-Calmettes Institute, whereas some were referred from other centers after a diagnosis of perforation. We described the characteristics of patients who underwent medical treatment alone or interventional procedures. Among patients who underwent interventional management, we compared the outcomes following early or delayed procedures (later than 24 h post-duodenal perforation diagnosis).

Overall, 78 patients with post-endoscopic duodenal perforation were identified between September 2003 and September 2022. Of these, 17 (22%) patients underwent non-operative management, and 61 (78%) with peritonitis or adverse clinical features were treated with endoscopic or surgical procedures. Additionally, among these patients, 40 (65%) underwent immediate invasive procedures, surgically (n = 20) or endoscopically (n = 20). Patients with delayed procedures experienced more major Clavien-Dindo ≥ 3 complications and had an increase by 21 of the median comprehensive complication index. Overall, mortality occurred in 7 (8.9%) patients in the entire cohort and in 3 (14.3%) with delayed invasive procedures.

Delayed decision-making is a key factor complicating post-endoscopic duodenal perforation. Therefore, invasive procedures should be performed promptly in cases of adverse conditions requiring additional procedures, ideally within the first 24 h of perforation diagnosis.
