    Secreted by parietal cells

    HCl- maintains acidity 1.0 pH

    - destroy some bacteria ingested

    - aids also in digestion of food

    Intrinsic factor- aids in absorption of Vit B12

    Secreted by entero- endocrine cells

    Gastrin, somatostatin ,serotonin, endorphins and histamines.

    Gastrin- regulates secretion and motility of the stomach

    Laparoscopy direct visualization of the organs and structures within the abdomen

    Laparoscopic surgery, also called minimally invasive surgery (MIS), band aid surgery, or keyhole surgery

    It is a modern surgical technique in which

    operations in the abdomen are performed

    through small incisions (usually 0.51.5 cm)

    Endoscopic retrograde

    cholangiopancreatography (ERCP)

    examination of the hepatobiliary system

    Paracentesis trans-abdominal removal of fluid from the peritoneal cavity for analysis

    Liver Biopsy

    Post- Procedure:

    Place on the right side with pillow under coastal margin.

    Avoid heavy lifting and strenuous activities for a week.

    Maintain bed rest for several hours.

    Urea breath test detects the presence of helicobacter pylori, the bacteria that causes_____

    Procedure: patient consumes a capsule of carbon-labeled urea and provides a breath sample 10 to 20

    mins later.

    Several medications has to be avoided prior to the test: antibiotics (1 month) carafate and omeprazole (

    1 week ) and H2 blockers (24 hrs)

    Sigmoidoscopy

    Colonoscopy

    Gastroscopy

    Gastroesophageal reflux

    DESCRIPTION:

    Backflow of gastric contents into the esophagus

    Usually due to incompetent lower esophageal sphincter , pyloric stenosis or motility disorder

    Symptoms may mimic heart attack

    Do you know why I took up nursing? It was in 4th year high school that I saw a vision of a great

    woman bearing a light in her right hand wearing a long gown and a headress calling me to serve

    her.

    TRY THIS!!!

    Is it possible that stomach will digest itself?

    No, because of

    MUCOUS GLANDS

    Mucous glands

    prevent autodigestion

    by providing

    an alkaline protective

    covering

    LAUGH BREAK

    Bakla at Macho nagkasabay sa CR...

    Bakla: Ang laki naman nyan sayo...

    Macho: Wala na tong silbi kasi iniwan na ako ng GF ko... puputulin ko na

    lang at ipapakain ko sa aso!

    Bakla: aw! aw! aw!

    Gastric Ulcer

    -50 y/o and above

    -lower socioeconomic class

    -20% incidence

    -normal to hyposecretion of HCl

    -pain at meal

    -hematemesis

    HIATAL HERNIA

    Esophageal or diaphragmatic hernia

    Portion of the stomach herniates diaphragm thorax

    Weakening of the muscles of the diaphragm & aggravated by fx that abdominal pressure

    i.e. pregnancy, ascites, obesity, tumors, and heavy lifting

    Cx:

    ulceration, hemorrhage, regurgitation and aspiration of stomach contents, strangulation, and

    incarceration of the stomach in the chest with possible necrosis, peritonitis, and mediastinitis

    HIATAL HERNIA

    Assessment

    Heartburn

    Regurgitation or vomiting

    Dysphagia

    Feeling of fullness

    HIATAL HERNIA

    Implementation

    Medical and surgical management is similar to that for GER

    Provide small, frequent meals and minimize the amount of liquids

    Advise the client not to recline for 1 hour after eating

    Avoid anticholinergics, which delay stomach emptying

    Destroys old RBC/blood reservoir

    Removes poisons from the blood

    Stores and releases glycogen as needed by the body

    Manufactures bile

    Storage of minerals and fat soluble vitamins

    Pancreas

    Both exocrine and endocrine gland

    Exocrine function is to secrete pancreatic enzymes amylase, lipase and trypsin

    Collects worn out RBC

    Disorders

    Liver Physiology and Pathophysiology

    fetor hepaticus (foul smelling breath)

    metabolism of nitrogenous waste products

    leads to azotemia to hepatic encephalitis (asterixis and decreased LOC)

    Predisposing Factors: 5 Fs

    Colorectal Cancer

    Cause: Unknown

    Most Common Site: rectosigmoid area

    Types of Colostomies

    Ascending colostomy

    Stoma is on the right of abdomen

    Fecal drainage is watery becomes pasty

    Transverse Colostomy-Transverse portion

    - middle of the abdomen

    - output: liquid initially-semiformed to paste like in 4-6weeks

    Descending and Sigmoid Colostomy

    Stoma on the left of the abdomen

    Fecal drainage is well-formed

    Colonic Surgery

    Postop Care

    Managing the perineal wound

    6months to completely heal

    Wound irrigations with NSS and absorbent dressings until wound closes.

    Drainage is initially copious and serosanguinous, to be drained regularly

    Stoma Monitoring

    Stoma is red and with slight edema for 5-7 days

    Dark, dusky or brown- black stoma indicates ischemia and necrosis

    Should protrude by to inches over abdomen Flatus and fecal drainage- begin in 4-7 days, as peristalsis returns Empty the pouch 1/3 full of stool

    - Teaching for self- care Stoma Care

    Gently encourage the client to look at the stoma Inform that stoma has no touch or pain sensation

    Skin care

    Wash the skin with warm water, pat dry when pouch seal leaks, change pouch immediately Use skin barrier to protect the peristomal skin from liquid stool Skin infection caused by Candida Albicans is treated with nystatin (

    Mycostatin) powder.

    Colostomy Irrigation

    Initial Irrigation- stimulate peristalsis; subsequent irrigations-promote evacuation of feces at a regular

    and convenient time

    Recommended with sigmoid colostomy

    Initiated 5-7 days postop

    Semi-fowlers position; sitting on a toilet bowl once able

    Use warm normal saline solution

    How to Irrigate..

    Initially, introduce 200ml of NSS then 500- 1000ml subsequently

    Dilate stoma with lubricated gloved finger before insertion of catheter

    Lubricate catheter before insertion

    Insert 2-4 inches of the catheter into the stoma

    Height of solution 18 inches above the stoma

    Abdominal cramps-temporarily stop the flow of solution until peristalsis relaxes

    Allow the catheter to remain in place for 5-10 minutes for better cleansing effect, then remove

    catheter to drain for 15-20 minutes.

    Clean the stoma, apply new pouch.

    Managing Odor

    Avoid gas- forming and foul odor foods

    Rinse pouch with tepid water or weak vinegar solution.

    Place deodorant tablet or small amount of mouthwash or a piece of charcoal into a pouch.

    Colonic Surgery

    Postop Care

    Supporting a Positive Self- Concept

    Encourage to view the stoma

    Encourage to verbalize feelings, fears and concern abou the stoma

    Encourage to participate in colostomy care

    Encourage to gradually resume all usual activities

    Preventing Sexual Dysfunctions

    Explore positions that minimize stress and pressure on the pouch

    Empty and clean the pouch before sexual activity

    Use smaller- sized pouch or pouch cover during sexual activity

    Use of a binder or special underwear to hold the pouch secure
