Evaluating the Evolving Morbidity of Omentoplasty for Perforated Peptic Ulcer Disease

Abstract

Mortality for perforated peptic ulcer (PPU) surgery ranges from 2-22% with morbidity ranging from 15-45%. Traditionally, these had been repaired with vagotomy and antrectomy or pyloroplasty with smaller perforations repaired with an omentoplasty. Laparoscopic repair has become increasingly prevalent and demonstrated to have shorter length of stay (LOS) and fewer complications. We are evaluating the surgical repair of PPU with omentoplasty to determine trends of utilization and surgical outcomes. We conducted a 13-year (2005-2017) retrospective review, utilizing the National Surgical Quality Improvement Program database. A total of 6873 patients had open or laparoscopic repair of a PPU, with 2285 patients identified as utilizing omentoplasty. Five hundred eighty-eight omentoplasty patients were further identified as having a laparoscopic technique. We compared patient demographics, comorbidities, and perioperative morbidity and mortality for surgical patients between 2005-2011 and 2012-2017. We trended the perioperative outcomes across the study intervals. Parametric and nonparametric tests were used to evaluate outcomes. Between 2005 and between 2017, laparoscopic surgical repair with omentoplasty has increased from 3.8% to 34.6%. Overall mortality for open operations declined during this interval (12.7%-9.3%) while it remained unchanged for laparoscopic operations (4.6%-4.2%), there was not a significant difference between the laparoscopic and open 30-day mortality. Both open surgery and laparoscopic surgery are being used on an increasingly healthy cohort (increased functional status decreased predicted perioperative morbidity). Relative to the 2005-2011, the laparoscopic surgery 2012-2017 cohort had increases in both serious and overall morbidity, although this was not statistically significant. Compared to the 2005-2011, the 2012-2017 open surgery cohort had increasing serious morbidity (OR 2.03) and overall morbidity (OR 1.91). There was a trend of decreasing LOS and increased return to the operating room for patients with laparoscopic surgery. Laparoscopic Graham patch repair of peptic ulcers significantly increased, although open repair still constitutes the majority of the cases. Despite Graham patch repair being utilized on a healthier patient population, morbidity and mortality for laparoscopic repair have remained unchanged. Postoperative morbidity and mortality for open surgery have increased. This indicates that laparoscopic repair is more commonly utilized for low- or medium risk patients, leaving an increasingly sick patient population selected to open repair.
