What are the causes of melena?

A

gastric cancer, duodenal ulcers, right-sided colon cancer, portal hypertension with esophageal varices, severe erosive esophagitis, Mallory-Weiss syndrome

113

A

bright red blood per rectum (BRBPR) - lower GI bleed

114
Q

What are the causes of hematochezia?

A

hemorrhoids, anal fissure, polyps, proctitis, rectal ulcers, and colorectal cancer
-diverticulosis is generally an incidental finding, since diverticular bleeding is usually of greater volume

115
Q

What is postoperative nausea and vomiting?

A

an unpleasant complication affecting 30 percent of children and adults after anesthesia
-vomiting or retching can result in wound dehiscence, esophageal rupture, aspiration, dehydration, increased intracranial pressure, and pneumothorax

116
Q

What is the cause of nausea?

A

can have causes that aren’t due to underlying disease

  • examples include motion such as a car and plane, taking pill on an empty stomach, eating too much or too little, or drinking too much alcohol
  • gastroenteritis
  • common cold
  • migraine headache
  • food poisoning
  • influenza virus
  • pyloric stenosis
  • peptic ulcer disease
  • hiatal hernia
117
Q

What is pancreatic carcinoma?

A

an elderly man with large nontender palpable gallbladder (Courvoisier’s sign)
-painless jaundice is pathognomonic

118
Q

What are the characteristics of pancreatic carcinoma?

A
  • the 4th leading cause of death form cancer in the U.S.
  • the disease is slightly more common in men than in women and risk increases with age
  • the cause is unknown, but the incidence is greater in smokers
  • almost one-third of cases of pancreatic carcinoma can be attributed to cigarette smoking and ETOH abuse
  • most commonly ductal adenocarcinoma located at the pancreatic head
119
Q

What is the presentation of pancreatic carcinoma?

A
  • weight loss/epigastric pain, clay-colored stools
  • jaundice + palpable non-tender gallbladder (Courvoisier’s sign)
  • virchow’s node (or signal node) is a lymph node in the left suprclavicular fossa (the area above the left clavicle) that is associated with pancreatic cancer
120
Q

How is pancreatic carcinoma dx?

A
  • ERCP
  • abdominal CT scan: 75% show tumor at the head of the pancreas, 25% at the tail
  • pancreatic bx
  • abdominal MRI
  • elevated serum bilirubin
  • abnormal liver function tests
  • CA 19-9 is present in about 80% of patients who have pancreatic cancer
121
Q

What is the tx of pancreatic carcinoma?

A
  • at the time of diagnosis, only about 20% of pancreatic tumors can be removed by the standard procedure is called a pancreaticoduodenectomy (Whipple procedure)
  • when the tumor is confined to the pancreas but cannot be removed, a combination of radiation therapy and chemotherapy may be recommended
122
Q

What is pancreatic pseudocyst?

A

pancreatitis and a palpable epigastric mass

  • cystic collection of tissue, fluid, and necrotic debris surrounding the pancreas
  • classically occur 2-3 weeks after acute pancreatitis
  • presents with abdominal pain and a palpable epigastric mass
  • CT scan is the study of choice
123
Q

What is the tx for pancreatic pseudocyst?

A

if pseudocyst persists for 4-6 weeks or continues to enlarge

  • surgical decompression (pancreaticogastrostomy)
  • percutaneous drainage
  • can become infected and lead to peritonitis
124
Q

What is peptic ulcer disease?

A

duodenal ulcer (food classically relieves pain think duodenum = decease with food)

  • ct scan is the study of choice
  • gastric ulcer (food classically causes pain)
125
Q

What is pyloric stenosis?

A

an infant with projectile vomiting

  • palpable epigastric olive-shaped mass (is pathognomonic for the disorder)
  • on ultrasound, you will see a “double-track”
  • barium studies will reveal a “string sign” or “shoulder sign”
126
Q

What is the treatment for pyloric stenosis?

A

by pyloromyotomy - known as Ramstedt procedure

127
Q

What is small bowel carcinoma?

A

the most common presenting symptom of small bowel tumor is abdominal pain-typically intermittent and cramps in nature

128
Q

What are the characteristics of small bowel carcinoma?

A
  • adenocarcinomas represent from 25 to 40 percent of small bowel cancers - highest in the duodenum
  • Crohn’s disease predisposes to adenocarcinoma within the involved area of the small intestine
129
Q

How is small bowel carcinoma dx?

A

radiographic (computed tomography [CT] scan, small bowel series, enteroclysis ) or endoscopic (wireless capsule endoscopy, push enteroscopy, double-balloon endoscopy)

130
Q

What is the tx for small bowel carcinoma?

A

surgery - localized adenocarcinomas of the small bowel are best managed with wide segmental surgical reaction
-adjuvant chemotherapy to patients with lymph node-positive

131
Q

What is toxic megacolon?

A

a 24-year old man with ulcerative colitis receives Lomotil for excessive diarrhea and develops fever, abdominal pain and tenderness, and a massively dilated colon on abdominal x-ray

  • toxic patient: sepsis, febrile, abdominal pain
  • megacolon: acutely and massively distended colon
  • can occur with IBD (UC>Crohn’s)
132
Q

What is the tx for toxic megacolon?

A

decompression of the colon is required

-In some cases, colostomy or even complete clonic resection may be required
