A 63-year-old man presents to the ambulatory medical clinic with symptoms of dysphagia and ‘heartburn’, which he states have become more troublesome over the past year. Past medical history is significant for primary hypertension. On physical exam, he is somewhat tender to palpation over his upper abdomen. The vital signs include: temperature 36.7°C (98.0°F), blood pressure 126/74 mm Hg, heart rate 74/min, and respiratory rate 14/min. Barium swallow fluoroscopy demonstrates a subdiaphragmatic gastroesophageal junction, with herniation of the gastric fundus into the left hemithorax. Given the following options, what is the most appropriate next step in the management of this patient’s underlying condition?

A 63-year-old man is brought to the emergency department, 30 minutes after being involved in a high-speed motor vehicle collision. He is obtunded on arrival. He is intubated and mechanical ventilation is begun. The ventilator is set at a FiO2 of 60%, tidal volume of 440 mL, and positive end-expiratory pressure of 4 cm H2O. On the third day of intubation, his temperature is 37.3°C (99.1°F), pulse is 91/min, and blood pressure is 103/60 mm Hg. There are decreased breath sounds over the left lung base. Cardiac examination shows no abnormalities. The abdomen is soft and not distended.

An x-ray of the chest shows deepening of the costophrenic angle on the left side. Which of the following is the most appropriate next step in management?

A 68-year-old man is brought to the emergency department because of fever, progressive weakness, and cough for the past five days. He experienced a similar episode 2 months ago, for which he was hospitalized for 10 days while visiting his son in Russia. He states that he has never fully recovered from that episode. He felt much better after being treated with antibiotics, but he still coughs often during meals. He sometimes also coughs up undigested food after eating. For the last 5 days, his coughing has become more frequent and productive of yellowish-green sputum. He takes hydrochlorothiazide for hypertension and pantoprazole for the retrosternal discomfort that he often experiences while eating. He has smoked half a pack of cigarettes daily for the last 30 years and drinks one shot of vodka every day. The patient appears thin. His temperature is 40.1°C (104.2°F), pulse is 118/min, respirations are 22/min, and blood pressure is 125/90 mm Hg. Auscultation of the lungs shows right basal crackles. There is dullness on percussion at the right lung base. The remainder of the physical examination shows no abnormalities. Laboratory studies show: Hemoglobin 15.4 g/dL Leukocyte count 17,000/mm3 Platelet count 350,000/mm3 Na+ 139 mEq/L K+ 4.6 mEq/L Cl- 102 mEq/L HCO3- 25 mEq/L Urea Nitrogen 16 mg/dL Creatinine 1.3 mg/dL An x-ray of the chest shows a right lower lobe infiltrate. Which of the following is the most likely explanation for this patient's symptoms?

A 68-year-old man comes to the physician because of a 6-month history of difficulty swallowing pieces of meat and choking frequently during meal times. He also sometimes regurgitates foul-smelling, undigested food particles. Examination shows a 3 x 3 cm soft cystic, immobile mass in the upper third of the left side of his neck anterior to the left sternocleidomastoid muscle that becomes prominent when he coughs. A barium swallow shows an accumulation of contrast on the lateral aspect of the neck at the C5 level. Which of the following is the most likely underlying cause for this patient's condition?

A 68-year-old man presents to the office with his wife complaining of difficulty in swallowing, which progressively worsened over the past month. He has difficulty in initiating swallowing and often has to drink water with solid foods. He has no problems swallowing liquids. His wife is concerned about her husband's bad breath. Adding to his wife, the patient mentions a recent episode of vomiting where the vomit smelled 'really bad' and contained the food that he ate 2 days before. On examination, the patient's blood pressure is 110/70 mm Hg, pulse rate is 72/min, with normal bowel sounds, and no abdominal tenderness to palpation. A barium swallow radiograph is performed (shown below), which reveals a localized collection of contrast material in the cervical region suggestive of an outpouching. Which of the following statements best describes the lesion seen on the radiograph?
