Successful Conservative Management of Hepatic Portal Venous Gas Following Percutaneous Endoscopic Gastrostomy: A Case Report.

BACKGROUND Hepatic portal venous gas (HPVG) is a rare radiologic finding mostly associated with life-threatening diseases like bowel necrosis, but can also be benign; its overall mortality rate is 39-75%. In rare cases HPVG is associated with endoscopic procedures such as percutaneous endoscopic gastrostomy (PEG) placement. However, due to the rarity of this condition, there is no recommendation about its management. The aim of this case report was to describe a successful conservative management of HPVG without antibiotic administration based on the clinical presentation. CASE REPORT A 78-year-old male patient known for a history of esophageal cancer treated with radio- and chemotherapy, complicated by a post-radiation esophageal stenosis requiring a PEG tube placement 1 month prior was admitted to our Emergency Department for vomiting and abdominal pain. A contrast-enhanced abdominal CT scan showed small-bowel dilatation without obstruction, as well as gastric wall pneumatosis and HPVG. We opted for a conservative approach. The PEG was put to suction for 2 days. The clinical evolution was favorable, with resolution of abdominal pain and a restored transit on day 2. A follow-up CT scan at day 5 showed resolution of HPVG. Nutrition through the PEG was restored at day 6 without complication. CONCLUSIONS HPVG can be a benign finding after a PEG tube placement. Conservative management without antibiotics can be used in oligosymptomatic and hemodynamically stable patients after life-threatening associated diseases like bowel necrosis have been ruled out.

Performance of quick sequential organ failure assessment and modified age disease adjusted qadSOFA for the prediction of outcomes in emergency general surgery patients.

BACKGROUND: Sepsis is a highly prevalent condition and is associated with a reported in-hospital mortality rate up to 40% in patients with abdominal sepsis requiring emergency general surgery (EGS). The quick sequential organ failure assessment score (qSOFA) has not been studied for EGS patients. METHODS: Retrospective cohort study in adult patients undergoing abdominal EGS at a university tertiary care center from 2016 to 2018. The primary outcome was mortality. The effect of clinical variables on outcomes was assessed in univariable and multivariable logistic regression analyses. Based on these results, the qSOFA score was modified. The performance of scores was assessed using receiver operating characteristics. RESULTS: Five hundred seventy-eight patients undergoing abdominal EGS were included. In-hospital mortality was 4.8% (28/578). Independent predictors for mortality were mesenteric ischemia (odds ratio [OR] 15.9; 95% confidence interval [CI] 5.2-48.6; p < 0.001), gastrointestinal tract perforation (OR 4.9; 95% CI 1.7-14.0; p = 0.003), 65 years or older (OR 4.1; 95% CI 1.5-11.4; p = 0.008), and increasing qSOFA (OR 1.8; 95% CI 1.2-2.8; p = 0.007). The modified qSOFA (qadSOFA) was developed. The area under the receiver operating characteristic curve of the qSOFA and qadSOFA for mortality was 0.715 and 0.859, respectively. Optimal cutoff value was identified as qadSOFA ≥ 3 (Youden Index 64.1%). CONCLUSION: This is the first study investigating the qSOFA as a predictor for clinical outcomes in EGS. Compared with the qSOFA, the new qadSOFA revealed an excellent predictive power for clinical outcomes. Further validation of qadSOFA is warranted. LEVEL OF EVIDENCE: Diagnostic test/criteria; Level II.

Impact of Inter-Hospital Transfer on Outcomes in Patients Undergoing Emergency Abdominal Surgery: A Tertiary Referral Center's Perspective.

BACKGROUND: In trauma patients, the impact of inter-hospital transfer has been widely studied. However, for patients undergoing emergency abdominal surgery (EAS), the effect of inter-hospital transfer on outcomes is largely unknown. METHODS: This is a single-center, retrospective observational study. Outcomes of transferred patients undergoing EAS were compared to patients primarily admitted to a tertiary care hospital from 01/2016 to 12/2018 using univariable and multivariable analyses. The primary outcome was in-hospital mortality. RESULTS: Some 973 patients with a median (IQR) age of 58.1 (39.4-72.2) years and a median body mass index of 25.8 (22.5-29.3) kg/m2 were included. The transfer group comprised 258 (26.3%) individuals and the non-transfer group 715 (72.7%). The population was stratified in three subgroups: (1) patients with low surgical stress (n = 483, 49.6%), (2) with hollow viscus perforation (n = 188, 19.3%) and (3) with potential bowel ischemia (n = 302, 31.1%). Neither in the low surgical stress nor in the hollow viscus perforation group was the transfer status associated with mortality. However, in the potential bowel ischemia group inter-hospital transfer was a predictor for mortality (OR 3.54, 95%CI 1.03-12.12, p = 0.045). Moreover, in the hollow viscus perforation group inter-hospital transfer was a predictor for reduced hospital length of stay (RC -10.02, 95%CI -18.14/-1.90, p = 0.016) and reduced severe complications (OR 0.38, 95%CI 0.18-0.77, p = 0.008). CONCLUSION: Other than in patients with low surgical stress or hollow viscus perforation, in patients with potential bowel ischemia inter-hospital transfer was an independent predictor for higher mortality. Taking into account the time sensitiveness of bowel ischemia, efforts should be made to avoid inter-hospital transfer in this vulnerable subgroup of patients.
