A simulation finite element model for the mechanics of the internal oblique muscle: A defense mechanism against inguinal hernia formation?

Hematemesis Secondary to Complex Incarcerated Pantaloon Hernia

Hematemesis with concomitant small bowel obstruction is an uncommon emergency department presentation. We report the case of a patient who presented with hematemesis and an incarcerated pantaloon hernia. While the patient initially had intact bowel movements and flatus, he eventually developed complete obstruction that required open surgical repair. In a patient with an incarcerated hernia and a history of recurrent small bowel obstruction, predicting strangulation or compromised bowel and the need for rapid surgical intervention can be difficult. Hematemesis concurrent with hernia incarceration may be suggestive of impending complete bowel obstruction and ischemia.

Causative factors for de novo inguinal hernia after robot-assisted radical prostatectomy

To determine causative factors for de novo inguinal hernia (IH), after robot-assisted radical prostatectomy (RARP). This was a retrospective, single-center study, which included patients undergoing RARP for prostate cancer at our institution, from February 2012 to January 2015. Cox proportional hazards models were used to determine the relationships between de novo IH and various factors. A total of 284 patients were included in the analysis. Forty-two (14.7%) patients developed IH at a median period of 8 months after RARP. On multivariate analysis, preoperative international prostate symptom score question 6 > 2, and a patent processus vaginalis were significantly correlated with de novo IH (hazard ratio (HR) 4.17, 95% confidence interval (CI) 2.07-8.37, p < 0.001; HR 3.67, 95% CI 2.36-5.69, p < 0.001). Preoperative urinary straining and a patent processus vaginalis were predictive of de novo IH after RARP.
