You are beginning a laparoscopic right colectomy in a 68-year-old woman with chronic obstructive
pulmonary disease and diabetes mellitus. After you have obtained pneumoperitoneum, you inspect
the abdomen and are alerted by your anesthesia colleagues that the patient is bradycardic to 38
beats/min and hypotensive. What is the best first response to this situation?
Desufflate the pneumoperitoneum and observe for response.
Likely this initial bradycardia and hypotension following insufflation is due to a vagal response from
which the patient will recover with desufflation of the abdomen.
In certain more debilitated patients, pneumoperitoneum is not tolerated because of its cardiovascular
and pulmonary effects, and laparoscopic surgery cannot be safely performed.
... is the rectosacral fascia in both males and females
Waldeyers fascia (posterior)
What should be added for acute flares of Ulcerative Colitis with possible infection or Toxic
Megacolon?
Ciprofloxacin and flagyl
What portions of the colonic layers does ulcerative colitis involve?
Mucosa and Submucosa (UC)
What portions of the colon are retroperitoneal?
Ascending, descending and sigmoid colon
What portions of fascia should be resected in patients with rectal tumors?
Waldeyer's and Denonvillier's
What portion of the colon is the most common site of primary colorectal cancer
Sigmoid colon
,What portion of the colon is likely involved with a perforation with ulcerative colitis?
Transverse colon
What portion of the colon is likely involved with a perforation with Crohn's?
Distal Ileum
What portion of the colon does ulcerative colitis tend to spare?
Anus (unlike crohn's)
What parts of the rectum are covered by the peritoneum?
Anterior upper and middle 1/3 of the rectum
What other portion of the GI tract needs to be checked for polyps in patients with FAP?
Duodenal polyps can occur so dudenum needs to be checked every 1-2 years with endoscopy
What other disease process is commonly seen in patients with angiodysplasia?
Aortic stenosis
What operation should be performed in patients with elective resections for ulcerative colitis?
Ileoanal anastomosis - rectal mucosectomy, J-pouch, and ileoanal (low rectal) anastomosis; not used
with Crohn's disease (Can protect bladder and sexual function, need lifetime surveillance of residual
rectal area, many ileoanal anastomoses need resection secondary to cancer, dysplastic changes,
refractory pouchitis, or pouch failure (incontinence) need temporary diverting ileostomy (6-8 weeks)
while pouch heals)
What operation should be performed in a patient with an emergent/urgent resection for ulcerative
colitis?
Total abdominal colectomy and bring up ileostomy (Hook it up later)
What must the rate of bleeding be for tagged RBC scan?
>0.1cc/min
What must the rate of bleeding be for arteriorgraphy?
>0.5cc/min
What margins are generally needed when operating on colon cancer?
2 cm
What is the treatment for Yersinia?
Tetracycline or Bactrim
What is the treatment for sigmoid volvulus?
, Decompress with colonoscopy (80% reduce, 50% will recur), give bowel prep, and perform sigmoid
colectomy during same admission (Pending success of decompression or viability of mucosa surgery may
be able to be done later if, unsuccessful or nonviable, surgery same admission)
What is the treatment for right-sided diverticulitis
Right hemicolectomy (80% found during incision for appy)
What is the treatment for patients with rectal pain and rectal caner?
APR
What is the treatment for patients with FAP?
All need total colectomy prophylactically at age 20 (Do not need colonoscopy for surveillance in patients
with suspected FAP just need flex sig to check for polyps)
What is the treatment for pathology showing T2 lesion after Transanal excision of villous rectal polyp?
Need APR or LAR
What is the treatment for ogilvie's syndrome if the colon is >10cm?
High risk of perforation --> decompression with colonoscopy and neostigmine, cecostomy if that fails
What is the treatment for ogilvie's syndrome <10cm?
IVFs; check and replace electrolytes (especially K and Mg); discontinue drugs that slow the gut (eg
morphine); NGT; neostigmine
What is the treatment for neutropenic typhlitis (entercolitis)?
ABX; patients improve when WBCs increase (surgery only if perforation)
What is the treatment for Lynch Syndromes?
Need for total proctocolectomy with first cancer operation
What is the treatment for low rectal T2 or higher cancer?
APR or LAR
What is the treatment for low rectal carcinoids that are >2cm or invasion of muscularis propria?
APR for >2cm or invasion of muscularis propria
What is the treatment for low rectal carcinoids that are <2cm?
Wide local excision with negative margins
What is the treatment for colovesicular fistula?
Close bladder opening, resect involved segment of colon, and perform reanastomsis, diverting
ileostomy; interpose omentum between the bladder and colon
