A closed loop obstruction caused by entrapment of the fallopian tube and herniation through the broad ligament
A 49-year-old female presented with one week history of severe abdominal pain, vomiting and constipation. Pertinent past surgical history consisted of caesarean section, laparoscopic right fallopian tube cystectomy and myomectomy. There was also recent left mastectomy and adjuvant chemotherapy for breast carcinoma. Clinical examination established a tensely distended abdomen with scanty bowel s...
متن کاملExtreme bradycardia and transient asystole after massive gastric air entrapment
A 72 year old male was scheduled for radiofrequency ablation of persistent atrial fibrillation under general anesthesia. After induction, and before orotracheal intubation, he developed severe bradycardia with a 4.3 second asystole and hypotension requiring atropin and external chest compressions (Panel A). Fluoroscopy revealed massive air entrapment inside the gastric cavity probably owing to ...
متن کاملAir entrainment in transient flows in closed water pipes: a two-layer approach
In this paper, we first construct a model for free surface flows that takes into account the air entrainment by a system of four partial differential equations. We derive it by taking averaged values of gas and fluid velocities on the cross surface flow in the Euler equations (incompressible for the fluid and compressible for the gas). The obtained system is conditionally hyperbolic. Then, we p...
متن کاملA transient-flow syringe air permeameter
In response to the need to better describe spatial variations in permeability, we designed and built a new portable field air permeameter for use on rocks in outcrop and core. In this instrument, a chamber containing a small volume of air in contact with the rock is suddenly increased in volume creating a vacuum, causing air to flow from the rock into the chamber. The instantaneous chamber volu...
متن کاملIntestinal Obstruction Caused by Phytobezoars
INTRODUCTION A 55-year-old woman with a 3-month history of abdominal pain presented to the emergency department with chief complaints of worsening abdominal pain and per os intolerance since 3 days ago. Her medical history was noteworthy for watery diarrhea without fever, loss of appetite, weight loss, and nausea and vomiting. Examination revealed abdominal tenderness over right and left lower ...
