Lecture 11 Flashcards
common nutr diagnoses with PUD
inadequate oral intake, inadequate energy intake, altered GI fxn, unintended wt loss, food and nutrition related knowledge deficit
management of PUD pharmacotherapy:
antacids, PPI, prostaglandin analogs, mucosal barrier fortifiers, H2 receptor agonists
this med causes black stool
peptobismal
what is h pylori triple therapy?
7-14 day course 2 antibiotics + PPI (cause nausea, vomiting, ab pain)
management of PUD nutrition:
prevent wt loss and restore nutrient interactions, support med therapies and v symptoms, trial restriction of foods increasing acid secretion, avoid foods not tolerated, avoid lying down after eating, avoid larger meals close to bedtime, small/frequent meals, omega 3 and 6 f.a.?
historical diet treatment of PUD:
milk and cream (but now know that they increase gastrin and pepsin secretion so don’t recommend)
one of major diffs between GERD and PUD nutrition management:
don’t restrict acid foods/juices for PUD
acute symptomology of PUD:
sharp, sudden, persistent, severe pain; melena (bloody/black stools), hematemesis (vomiting blood, coffee ground emesis)
acute symptomology of PUD indicative of serious complications like:
acute/chronic GI bleed, perforation, obstruction (big drops in Hb)
when use surgery for PUD?
when severe, refractory to treatment, complications
types of surgery for PUD:
vagotomy, gastroenterostomy
what is vagotomy?
interruption of impulses carried by vagus nerve to parietal cells (v acid production, v response to gastrin)
preferred vagotomy for treating PUD
highly selective vagotomy (preserves antral motility)
what is truncal vagotomy with pyloroplasty?
vagus nerve cut at distal esophagus to decrease antral contraction, delay emptying of solids, v pylorus relaxation; pyloroplasty is surgical revision to widen pyloric canal that creates leaky pylorus to enhance emptying (can cause dumping, less control of food flow)
what is a gastrectomy?
resection of stomach (partial or total) –>used in gastric CA, more aggressive
alternative to pyloroplasty:
gastric remnant of partial gastrectomy anastomosed to small intestine
primary gastric surgeries for PUD:
gastroduodenostomy (billroth 1), gastrojejunostomy (Billroth 2) , roux-en-Y anastomosis
what is billroth 1?
removal of pylorus and/or antrum of stomach, anastomosis of proximal end of duodenum to distal end of remnant stomach
