2022-01-25 16:02:01 In patients with liver failure, the source of an upper GI bleed is esophageal varices in 50%, gastritis in 30%, and duodenal ulcers in only about 10%. Esophageal variceal bleeding is a potentially fatal complication of portal hypertension. The initial management should include fluid resuscitation and replacement of blood and clotting factors as needed. The second step is to control the source of bleeding. Medical management may include vasopressin or octreotide. Once the patient is stabilized, endoscopic evaluation of the bleeding is crucial. It can be both diagnostic and therapeutic. Endoscopic techniques for controlling hemorrhage can include sclerotherapy, banding, or balloon tamponade. If these methods are ineffective, or the patient has numerous recurrences, portal shunts can be considered. TIPS have increased in popularity as a method for portal decompression. This can be performed in the acute setting. Surgical shunts are also an option, but are primarily reserved for stable patients with recurrent bleeding episodes and not performed in an acutely unstable patient. Mesocaval shunts connect the SMV to the IVC in a variety of manners. Splenorenal shunts are actually the most common type of shunt. Nonselective shunts that completely divert portal blood flow from the liver can actually increase hepatic encephalopathy. Most surgeons prefer selective shunts, which preserve a component of hepatic blood flow and thus function. Synthetic graft material can be safely used to create the shunts. Postoperative mortality is directly related to the patient’s preprocedure medical condition and degree of hepatic failure (i.e., Child class). Open / Comment

2022-01-24 12:59:40 38) A55-year-old man with hepatic cirrhosis from alcohol abuse presents with a massive hematemesis. This is his third admission for upper GI hemorrhage in the past 2 months. He is currently receiving appropriate therapy for liver failure, including a beta-blocker and diuretics. He is lethargic and confused. His pulse is 100 and blood pressure is 85/40. His initial hematocrit is 20. After fluid resuscitation, which of the following is the most appropriate management strategy? Open / Comment

2022-01-17 09:05:00 Pyloric stenosis usually presents in the first 4–8 weeks of life. Parents usually report nonbilious emesis after feeding, which progresses to a projectile nature. Untreated, this will become a complete obstruction. On examination, an “olive sign” or mass in the right upper quadrant is often found. Ultrasound is the best radiologic test. These infants may present with dehydration and metabolic abnormalities from the emesis. The most common abnormality is hypokalemic, hypochloremic metabolic alkalosis. While surgical correction is urgent, it is not emergent. These infants should be resuscitated with IV fluids and their metabolic derangements corrected before an operation. The surgical treatment is a pyloromyotomy, which involves splitting the hypertrophic muscles of the pylorus while keeping the mucosa intact. This can be performed either open or laparoscopically. Patients are usually allowed to feed within hours of their operation. Open / Comment
