Crohn’s disease -
a chronic, segmental inflammation that affects the entire thickness of the wall and potentially every segment of the gastrointestinal tract (that is, from the mouth to the anus).
Crohn’s disease
Symptoms:
diarrhea, abdominal pain, weight loss, weakness, perianal changes, anal fissures, abscesses, fistulas, tumors in the abdomen, leukocytosis
Crohn’s disease
Complications:
ileus, internal and external fistulas (especially perianal ) interloop abscesses, peritonitis, bleeding
Crohn’s disease
Diagnosis:
barium enema (rectal infusion) revealing “rose thorn” or “collar button” appearance
USG, MR
colonoscopy - ulcers, ecchymosis, “cobblestone” appearance
capsule endoscopy
Crohn’s disease
Treatment: conservative:
conservative: high-protein diet with the appropriate amount of vitamins and electrolytes, smoking cessation, pharmacological treatment (GCS, sulfasalazine, antibiotics, antidiarrheals, immunosuppressive, biological agents)
Crohn’s disease
Treatment: surgical:
surgical:
-small intestine disease - conservative resection or intraoperative dilation of small intestinal stenoses
-right or left half of the colon - hemicolectomy
-more extensive changes in the colon - colectomy with ileorectal anastomosis or proctocolectomy with permanent ileostomy
Percutaneous endoscopic gastrostomy (PEG)
is an endoscopic medical procedure in which a tube (PEG tube) is passed into a patient’s stomach through the abdominal wall, most commonly to provide a means of feeding when oral intake is not adequate (for example, because of dysphagia or sedation).
This provides enteral nutrition (making use of the natural digestion process of the gastrointestinal tract) despite bypassing the mouth; enteral nutrition is generally preferable to parenteral nutrition (which is only used when the GI tract must be avoided).
The PEG procedure is an alternative to open surgical gastrostomy insertion, and does not require a general anesthetic; mild sedation is typically used.
PEG tubes may also be extended into the small intestine by passing a jejunal extension tube (PEG-J tube) through the PEG tube and into the jejunum via the pylorus
The most common malignant tumor is stomach is
adenocarcinoma
- reduction in the incidence of peripherally localized stomach cancer
- increase in the incidence of cancer of the proximal part and cardia.
- dissemination of metastases most often via* lymphatic vessels*
- Most often, it is diagnosed at the stage, in which it is not possible to perform an operation leading to cure
Which should you suspect in a female patient complaining of cyclic regular hypogastric pain occurring for a longer time and rectal bleeding that accompanies menstruation?
endometriosis extragenitalis
Endometriosis -
the occurrence of the endometrium (glandular cells and stroma) outside the uterine cavity.
Symptoms:
limitation of fertility
pelvic pain syndrome, tenderness during examination, and palpable nodules in the projection of the uterine ligaments
dysmenorrhea (pain begns several days before the onset of menstruation)
dyspareunia
enlarged tender, weakly mobile appendages
Treatment:
Surgical:
removal of isolated foci
removal of endometrial cysts
removal of the entire ovary
removal of the entire uterus with appendages
pharmacological:
Hormone therapy:
Pain relievers:
Hormone therapy:
Gonadoliberin analogues
progesterone preparations
estrogen-progesterone preparations
IUD with levonorgestrol
aromatase inhibitors
selective progesterone receptor modulators (SPRMs)
Pain relievers:
NSAIDs
obstructive jaundice = ___ = ___
obstructive jaundice = post-hepatic jaundice = cholestasis
-is a result of impaired physiological flow of bile
-dominant symptoms: conjugated hyperbilirubinemia, pruritus of the skin
-if it is caused by an acute disease (e.g. biliary obstruction caused by a gallstone),
-symptoms of biliary colic appear (sudden, severe pain in the right hypochondrium, radiating to the shoulder blade or the shoulder, accompanied by flatulence, nausea, vomiting)
-dark urine and pale stool
Causes:
primary cholangiocarcinoma.
PSC
inflammation of the extrahepatic bile ducts
pancreatic head cancer
choledocholithiasis - deposits in the bile ducts
Acute pancreatitis
is an acute inflammation of the gland associated with damage to the follicular cells of the pancreas, as a result of which active proteolytic enzymes enter the connective tissue stroma, causing a local inflammatory reaction.
In 15-20% of patients, the inflammatory process leads to the formation of necrotic and / or abscesses, which results in severe, necrotizing pancreatitis.
Causes of Acute Pancreatitis (“I get smashed”):
I - Idiopathic ACS
G - Gallstones, urolithiasis
E - Ethanol, alcohol abuse
T - Trauma, injuries of the abdominal cavity
S - Steroids, glucocorticoid abuse
M - Mumps, viral infections (mumps, AIDS)
A - Autoimmune, autoimmune
S - Scorpion, scorpion venom
H - Hyperlipidemia, Hypercalcemia
E - ERCP, iatrogenic
D - Drugs, drug abuse - ACEI, GKS, azathioprine, erythromycin, anti-epileptic
Symptoms: of Acute Pancreatitis
Symptoms:
strong, continuous, rapidly increasing, girdling pain, located in the epigastrium, often radiating to the back, sometimes also to the chest and abdomen, increasing in standing position,
nausea and vomiting
flatulence
fever,
yellowing of the proteins,
in severe acute pancreatitis, tachycardia, hypotonia, tachypnoea, dyspnoea, confusion, impaired consciousness, intestinal paralytic obstruction may develop, DIC may develop.
What is ERCP?
**Endoscopic retrograde cholangiopancreatography, or ERCP,
-is a procedure to diagnose and treat problems in the liver, gallbladder, bile ducts, and pancreas.
-It combines X-ray and the use of an endoscope—a long, flexible, lighted tube.
What is decompensated diabetes?
presence of diabetic ketoacidosis (DKA) or hyperglycemic hyperosmolar state (HHS).
What are three signs of diabetic ketoacidosis?
DKA Signs and Symptoms
Fast, deep breathing.
Dry skin and mouth.
Flushed face.
Fruity-smelling breath.
Headache.
Muscle stiffness or aches.
Being very tired.
Nausea and vomiting.
Indicate tests that should be ordered before the abdominal puncture in a patient with hepatic cirrhosis:
- Ultrasound - to assess the amount of free fluid in the abdominal cavity and determine the site of puncture
- **complete blood count **- to assess the number of platelets, hemoglobin concentration
- coagulogram - to rule out possible coagulation disorders that may cause bleeding after the examination
What happens in abdominal compartment syndrome?
In abdominal compartment syndrome, the displacement of the diaphragm cephalad leads to compression of the thorax, which causes an increase in work of breathing, ventilation/perfusion inequality, and increases in both peak and plateau pressures.
What organs are commonly affected in abdominal compartment syndrome?
-Abdominal compartment syndrome (ACS) and intra-abdominal hypertension (IAH) are increasingly recognized as potential complications in intensive care unit (ICU) patients.
-ACS and IAH affect all body systems, most notably the cardiac, respiratory, renal, and neurologic systems
What causes abdominal compartment syndrome 1?
Extensive surgery in your abdomen.
Infection in your abdomen.
Intestinal obstruction (blockage).
Large amount of IV fluids (called fluid resuscitation), often required for surgery or sepsis.
Major burns.
Massive blood transfusion.
Pancreatitis.
