Background: The link between Helicobacter pylori infection and peptic ulceration is well established. Recent studies have reported a decrease of H. pylori-related peptic ulcer disease; Helicobacter pylori eradication is likely the cause of this decrease. We hypothesized that patients with H. pylori-positive perforated peptic ulcer disease (PPUD) requiring surgical intervention had worse outcomes than patients with H. pylori-negative PPUD. Patients and Methods: A prospectively collected Acute and Critical Care Surgery registry spanning the years 2008 to 2015 was searched for patients with PPUD and tested for H. pylori serum immunoglobulin G (IgG) test. Patients were divided into two cohorts: H. pylori positive (HPP) and H. pylori negative (HPN). Demographics, laboratory values, medication history, social history, and esophagogastroduodenoscopy were collected. Student t-Test was used for continuous variables and χ2 test was used for categorical variables. Linear regression was applied as appropriate. Results: We identified 107 patients diagnosed with PPUD, of whom 79 (74%) patients had H. pylori serum IgG testing. Forty-Two (53.2%) tested positive and 37 (46.8%) tested negative. Helicobacter pylori-negative PPUD was more frequent in females (70.27%, p = 0.004), whites (83.78%, p = 0.001) and patients with higher body mass index (BMI) 28.81 ± 8.8 (p = 0.033). The HPN group had a lower serum albumin level (2.97 ± 0.96 vs. 3.86 ± 0.91 p = 0.0001), higher American Society of Anesthesiologists (ASA; 3.11 ± 0.85 vs. 2.60 ± 0.73; p = 0.005), and Charlson comorbidity index (4.81 ± 2.74 vs. 2.98 ± 2.71; p = 0.004). On unadjusted analysis the HPN cohort had a longer hospital length of stay (LOS; 20.20 ± 13.82 vs. 8.48 ± 7.24; p = 0.0001), intensive care unit (ICU) LOS (10.97 ± 11.60 vs. 1.95 ± 4.59; p = 0.0001), increased ventilator days (4.54 ± 6.74 vs. 0.98 ± 2.85; p = 0.004), and higher rates of 30-day re-Admission (11; 29.73% vs. 5; 11.91%; p = 0.049). Regression models showed that HPN PPUD patients had longer hospital and ICU LOS by 11 days (p = 0.002) and 8 days (p = 0.002), respectively, compared with HPP PPUD. Conclusion: In contrast to our hypothesis, HPN patients had clinically worse outcomes than HPP patients. These findings may represent a difference in the baseline pathophysiology of the peptic ulcer disease process. Further investigation is warranted.
