Colorectal Flashcards
APR anatomical guidelines
Sacral promonotory (abdominal portion) Coccyx for the perineal and pelvic dissection
R hemi v extended R hemi
Ascending colon = R hemi
Transverse (hepatic flexure) = extended R hemi
Indications for Adjuvant in Colon cancer
stage II and high risk (lymphvascular invasion, t4, high preop CEA, close/pos margins, inadequate LN sample like 10)
Radionucleotide scan for LGIB
Capable of detecting bleeding rate as slow as 0.1-0.4 ml/min
high sensitivity
UC Severity scales
UC with colitis and signs of sepsis
IV Abx and steroids (methylpred 10 q8h or hydrocort 100 q 8 hours)
Most sensitive step while performing colonoscopy to r/o LGIB
Intubate the TI
MCC death for pts with FAP
Duodenal tumor – need EGD starting at 20
Cure for UC (under certain circumstances)
Total proctocolectomy with Ileal pouch anal anastomosis; ie high grade dysplasi in a polyp
Most likely place Cutaneous melanoma will metastasize?
Small bowel
Loop ileostomy closure is dictated by the resoultion of primary disease
usu 8-12 weeks ; def after chemotherapy
Infliximab (chimeric IgG-1 mAB with affintiy for TNFalpha) best for ___ Crohn’s
fistulizing
MCC of sever GI bleeding is older people is diverticular dz… when to take to the OR?
if HDU or if > 4 units of blood are needed
MAP (Mut Y homolog polyposis)
10 or more synchronous colon polyps
AR patterns
POST-Op surveillance for colorectal CA
Clinical exam and CEA every 3-6 months for 2 years, then every 6 mos for 5 years,
UC/Toxic megacolon (> 6 cm transverse, TTP, tachycardia and leukocytosis)
TAC and end ileostomy
