Video #1
A 68-year-old woman presented to the emergency room with lower abdominal pain and a large reducible right lower quadrant hernia. CT scan showed the origin of the hernia in the right inguinal region with the sac extending cephalad and laterally between the internal and external oblique muscles

Video #2
The patient was taken to the operating room for laparoscopic repair of the hernia. The initial approach was transabdominal (TAP) to visualize the defect and reduce the hernia.

Video #3
The defect is shown after reduction of the hernia contents.

Barium Enema and Double Contrast Study

Barium Enema and Double Contrast Study

http://info.med.yale.edu/surgery/anatomy/radiology/barium_enema_1_content.php

Yale school of medicine

SLIDES 1
Goals
1. GI tract is often injected with contrast medium to visualize abnormal anatomy and the contrast is frequently followed up with air for a “double contrast” study
2. The position of the patient is adjusted to visualize specific regions of the bowel
3. You should be able to relate the images to the surface anatomy of the patient and appreciate the changes in the position of the patient to achieve the various views.

SLIDE 2
Barium Study
- This is a double contrast BE (barium enema). For this test we put a small amount of contrast in the colon to coat the surface and then distend the colon with air.

SLIDE 3
Question: What is the main reason we perform a double contrast barium enema?
- to look for colon cancer
Question: This is an oblique view. The patient is lying on his left side. Do you see all of the contrast on the dependent side of the colon?
Qustion: What do you have to do to make sure that there is no polyps or cancers hiding in the dense contrast?
- flip the patient on to his right side

SLIDE 4
Question: Can you find the splenic and hepatic flexures on this image?
- hepatic flexure
- splenic flexure
Question: You could see how a lesion would be difficult to see in one of these flexures due to overlap of the colon. How could we clear this up?
- If we did more films with some obliquity we could eliminate this overlap

SLIDE 5
This is a single contrast barium enema (no air only contrast). Can you see the narrowing in the transverse colon?

Question: Do you know what this is?
- This is an adenocarcinoma. This is what is classically described as an apple core lesion.
Question: [...]

SLIDE 5
SUMMARY
1. In double contrast studies the patient often lies on one side and then the other to obtain films revealing the right and left walls of the large bowel.
2. Oblique views may be required to visualize the splenic and hepatic flexures

Angiograms of the Abdomen

Angiograms of the Abdomen

http://info.med.yale.edu/surgery/anatomy/radiology/abdominal_angiogram_content.php

SLIDE 1
Angiograms of the abdomen
- is a composite of angiograms taken from different patients.
- The position of the transumbilical plane is approximated by the red line.
- The three images on the right are standard x-ray films with reverse contrast (a positive was made from the x-ray negative)
- The image on the left was reconstructed from a CT study
- The individual images with labels can be viewed on the following pages

- celiac trunk
- superior mesenteric artery
- inferior mesenteric artery
- abdominal aorta with branches of the celiac trunk deleted

SLIDE 2
SUMMARY
1. The celiac and SMA originate close to each other, which the IMA originated more distally close to the transumbilical plane
2. Note the gross differences in the distribution of the vessels
3. The celiac branches are superior and on both sides of the midline
4. The SMA branches are widely distributed, through heavily in the upper left quadrant
5. The IMA branches are entirely on the left
6. In your further studies you should be able to identify what organs the major branches are supplying and where the vessels are located (i.e. in mesenteries or retroperitoneal)

Diverticulitis on CT scan

Diverticulitis on CT scan

http://info.med.yale.edu/surgery/anatomy/radiology/diverticulitis_content.php

SLIDE 1
Goals
To examine how diverticulitis affects the:
1. Wall of the colon
2. Lumen of the colon
3. Fat in the mesentery of the colon

SLIDE
Normal and diseases sigmoid colon are shown for comparison. The sigmoid colon is filled with contrast.
Compare:
- In the sigmoid colon: width of the colon, width of the lumen
- In the neighboring fat: stranding due to inflammatory response, normal fat

SLIDE 2
SUMMARY
1. Inflammation causes a thickening of the colon wall that narrows the lumen
2. Stranding is the radiographic appearance of an inflammatory response by the fat in the mesentery

Bookmark and Share

Renal Cell Carcinoma CT Scan

Renal Cell Carcinoma CT Scan

http://info.med.yale.edu/surgery/anatomy/radiology/renal_ca_content.php

SLIDE 1
Renal Cell Carcinoma
- Why does the right kidney look like a donut with bright stuff in the donut hole?
– the kidney treats venous contrast like a waste product and concentrates it in the urine

- Why is the tumor in the left kidney duller than the rest of the donut?
– the tumor is hypovascular in relation to the renal parenchyma

- Is this section closer to the transpyrolic, subcostal, or umbilical plane? Why?

– the transpyloric: the superior mesenteric artery branches off the aorta; the pancreas is present; ribs are present; renal arteries (subcostal plane) ureters (which whould be bright with contrast, are absent)

Bookmark and Share

Cholangiogram

Cholangiogram

http://info.med.yale.edu/surgery/anatomy/radiology/cholangiogram_content.php

SLIDE 1
Goals:
1. Relate the hepatoduodenal ligament and second portion of the duodenum to bony landmarks
2. Relate the pancreas to bony landmarks and the duodenum

SLIDE 2
- The gallbladder was removed
- To examine the integrity of the biliary system during surgery, a catheter was inserted in the ampulla of the duodenum.
Question 1. Besides the biliary tree, what other structure should be filed with contrast dye?
- the pancreatic duct, because it empties into the ampulla along with the bile duct.

SLIDE 3
Identify the following landmarks
- 12th rib
- L1 vertebrae
- L2 vertebrae
- catheter
- common bile duct and gallbladder
- pancreatic duct
- hepatoduodenal ligament
- 3rd portion of the duodenum (filled with contrast)
- infer the 2nd portion of the duodenum

SLIDE 4
SUMMARY
- The pancreatic and common bile ducts empty into the middle of the 2nd portion of the duodenum
- This portion of the duodenum is to the right of midline between L1 and L3; the 3rd portion crosses the midline at L3
- The body of the pancreas crosses the midline at L2
- The hepatoduodenal ligament begins near the midline near the L1/L2 disc (transpyloric plane) and angles towards the liver

- splenic vein (the left most arrow is the portal vein)
18d. What venous structure does this join to make up the portal vein?
- the splenic vein joins the superior mesenteric vein to make up the portal vein
19. What is the structure anterior and near the superior aspects of the left kidney?
- the left adrenal gland
20. Do you see the SMV in this image? Try tracing it from the junction of the splenic and portal veins. Trace the vein superiorly, where the splenic vein comes to join it from the portal vein.
21a. What part of the pancreas are these arrows defining?
Hint: it is the most inferior portion of the pancreas
- this is the pancreatic head
21b. What is this small pointed area medial to the head of the pancreas?
Hint: it is the most inferior portion of the pancreas
- this is the uncinate process
21c. What is this high attenuating structure (artery) just anterior to the uncinate process?
- the superior mesenteric artery
22a. What is this low attenuating structure in the pancreatic head?
- this is the intrapancreatic portion of the common bile duct.
22b. What is this tiny low attenuating structure in the pancreas?
- this is the pancreatic duct
23a. What are these 2 vascular structures?
- IVC (white arrow)
- Aorta (black arrow)
23b. Why is the aorta filled with contrast and the IVC is not?
Hint: Do we give our injections in the artery or vein? And do we inject in the upper or lower extremity?
- We inject intravenously in the upper extremity (arm), so the blood goes to the SVC to heart to arterial system then to lower extremity venous system
24. Do you see this patient’s tumor?
Hint: it is very subtle, it is right where the CBD enters the duodenum at the ampulla.
- If you picked up that tumor, you have a promising career in radiology!
25. What part of the colon is this?
Hint: it is anterior on a long mesentery
- this is the transverse colon

SUMMARY
- The exercise emphasizes important anatomy that should be traced superiorly and inferiorly to appreciate the three-dimensional structure

- The tumor is difficult to see in many images. Rather than focussing on pathology in the image you should be able to explain in simple terms how this tumor contributed to the patient’s jaundice.

Abdominal CT scan

Abdominal CT scan

http://info.med.yale.edu/surgery/anatomy/radiology/abdomen_ct_content.php

TOPICS
SLIDE 1
Goals
1. To understand vascular anatomy of the liver and how the vessels define the segmental anatomy of the liver
2. To review and understand the developmental anatomy and fetal circulation of the liver and what remnants are still present in the adult liver
3. To review colonic and small bowel anatomy and be able to predict where you may visualize different segments of bowel and axial CT
4. To understand the anatomy, relationships and orientation of the pancreas
5. To review and understand the relationships of major arterial and venous structures in the abdomen and pelvis and how they can be seen on axial CT

SLIDE 2
Questions
2. What is this high attenuation structure in the liver?
- this is the left portal vein.
1a. Do the portal veins divide the liver into segments?
- No. the hepatic veins do.
4a. What is this black line that runs through the liver?
- this is the fissure for the ligamentum teres
4b. What structure ran through this region?
- the umbilical vein
4c. What is this fissure anterior to the caudate lobe?
- this is the fissure for the ligamentum venosum
5a. what part of the colon is this?
- this is the distal transverse extending to the splenic flexure
5b. Why does the colon look white?
- the patient was given oral contrast
6. what portion of the pancreas is this?
- this is the tail
9. what portion of the colon is this?
- hepatic flexure
10. what is this venous structure extending from the left kidney to the IVC?
- this is the left renal vein
13. what portion of the colon is labeled by each arrow?
- ascending colon (black)
- descending colon (white)
14. What vessel is coming off the aorta?
- hint: it is colonic supply and below the level of the SMA
- inferior mesenteric artery
15. Look at the small bowel without contrast (white arrows) and the colon with contrast (black arrows) and note that the bowel wall is extremely thin. Normally it is approximately 3mm.
18. What is this small tubular structure partially filled with contrast on this and the subsequent image.
19. This is the appendix. Note this is normal; thin walled, filled with contrast and no inflammatory changes in the adjacent fat.
23. What portion of the colon is labeled with arrows?
- sigmoid colon
24. What vascular structures are marked by the arrows?
- the external iliac arteries and veins
26a. What is this fluid filled structure?
- the bladder
26b. What portion of bowel is this located posterior to the bladder and anterior to the sacrum?
- the rectum
26c. What is the significance of the space between the bladder and the sacrum?
- this is the most dependent portion of the peritoneal cavity in a male.

SLIDE 3
SUMMARY
- You will need to be able to navigate your way through CT and MRI images of the abdomen. This exercise focuses on important structures and represents an appropriate level of detail.
- You should become skilled at tracing structures superiorly and inferiorly to appreciate their relations in three dimensions.

http://info.med.yale.edu/surgery/anatomy/radiology/CT_kidney_content.php

TOPICS

SLIDE 1
Goals
1. Be able to identify the renal vessels, aorta and ureters as these structures are rotated in 3-D
2. Be able to explain the relative position of important nearby structures that are not shown such as the 12th rib and IVC

SLIDE 2
- CT reconstruction of the kidneys and renal arteries
- Rib 12 is colored blue, the abdominal aorta is pink and the renal arteries are red
- Transpyloric plane
- Subcostal plane

SLIDE 3
[...]

SLIDE 4
3-D reconstruction of kidneys and SMA vasculature
- aorta
- left renal artery
- left renal vein
- right renal artery
- left ureter
(and questions)
- right ureter
- SMA (superior mesenteric artery)
- IMA (inferior mesenteric artery)

SLIDE 5
- lumbar segmental arteries
(question)

SUMMARY
1. The renal vessels are at the subcostal plane
2. The left renal artery is posterior to the left renal vein
3. The kidneys are posterior to the aorta and IVC, so the vessels course posteriorly from the midline to reach their targets

- heart chambers
- liver
- air in the stomach
- arch of aorta
- manubrium
- sternal angle (angle of louis)

SUMMARY

1. The aorta moves from right to left as it arches from anterior to posterior, so the plane of the imaging must be oblique to capture the entirety of the arch

2. The arch of the aorta is at the same level as the angle of Louis

3. The major vessels from the arch arise posterior o the manubrium

Anal Cancer: Background Anal Cancer: Background

Malignancies of the anal cancer are relatively uncommon and represent only 2-3% of all anorectal carcinomas.

The position of the tumor in the anal canal relative to the dentate line is important with regard to the biologic behavior of the tumor.

This is based on the lymphatic drainage in these two areas.

Most tumors spread by direct extension and lymphatic drainage.

Hematologic spread is less common.

Anal tumors are classified into two groups based on location: 1) anal cana tumors  2) anal margin tumors

mnt reid p.452

Anal Cancer: Epidermoid carcinoma Anal Cancer: Epidermoid carcinoma

- Epidermoid carcinoma (1-2% of all colorectal carcinomas) are referred to as squamous, basaloid, cloacogenic, or transitional carcinomas.

- Although each has different histologic features, they exhiit similar biologic behavior and are thus grouped together.

- typically seen in patients 50-70 years of age

- seen more frequently in women

- two cell types – squamous cell (keratinizing) and transitional cell (nonkeratinizing)

- rectal pain, bleeding, or mass are common presenting symptoms

- 40-50% have pelvic lymph node involvement at diagnosis, whereas 15-36% have inguinal nodal involvement and 10% have distant metastasis

- excellent prognosis when discovered prior to nodal involvement and invasion to adjacent structures.

- 80% of tumors are cured by chemotherapy/radiation therapy alone

- chemotherapy with mitomycin C and 5-fluorouracil combined with radiation is the treatment of choice.

- this may be followed by surgical rsection

- abdominoperineal resection is indicated for residual disease or recurrence

mont reid p.453

Anal Cancer: Malignant melanoma Anal Cancer: Malignant melanoma

- 0.5-1% of malignant anal tumors

- anal canal is the 3rd most common site after skin and eyes

- typically occurs adjacent to the dentate line

- rectal bleeding is the most frequent complaint

- most are not highly pigmented, and diagnosis is difficult

- tumor is aggressive and often widely metastatic. abdominoperineal resection is indicated in selected patients.

- tumors often radioresistant and unresponsive to chemotherapy

- 5-yaer survival is <15%

Anal Cancer: Tumors of the anal margin

squamous cell carcinoma, basal cell carcinoma, bowen’s disease, paget’s disease of bone

Anal Cancer: Tumors of the anal margin

squamous cell carcinoma, basal cell carcinoma, bowen’s disease, paget’s disease of bone

- these tumors are similar to skin tumors elsewhere and are treated likewise

- include squamous cell and basal cell carcinomas, Bowen’s disease, and Paget’s disease of bone

Anal Cancer / Bowen: surgery resident handbook Anal Cancer / Bowen: surgery resident handbook

ANAL CANCER and BOWEN DISEASE

Anatomy-loosely speaking, above dentate line is columnar, below is squamous.  A 1cm transition zone (cloacogenic zone) is present which can contain columnar, cuboidal, or transitional epithelium.

Anal canal = 4cm tube from anal verge (what you see looking from outside) to anorectal ring (about 2cm above dentate line)

Anal margin = skin from anal verge to point 5cm away circumferentially.  Is the intersphincteric space.

Dentate line = transition point, located about 2cm above anal verge.

Term “anal cancer” comprises 2 entities: anal canal cancer (anal verge to 2cm above dentate line) and anal margin (anal verge out to 5cm skin) cancer.  Overlapping behavior and treatment.  Typically well-differentiated and slow growing.

Epidemiology: F:M 5:1, mean age 60s.  Associated with HPV genotypes 16 and 18, anal receptive intercourse, immunosuppressed states (HIV, organ transplant)

SSx: change in bowel habits, hematochezia, pain, urgency, tenesmus, pruritis.

Workup: punch or wedge biopsy diagnostic. Stage with EUS, exam of inguinal nodes with FNA for suspicious nodes, CT abdomen/pelvis, CXR.

ANAL CANAL LESIONS

EPIDERMOID (SQUAMOUS) CARCINOMA

Arises from the cloacogenic zone.  Includes

squamous cell carcinoma

basaloid carcinoma

cloacogenic

mucoepidermoid carcinoma.

generally spread to inguinal LNs. higher incidence of superior rectal LN metastasis.

Staging of anal canal cancers

T1  Tumor <2cm

T2  Tumor 2-5cm

T3  Tumor >5cm

T4  Tumor of any size with invasion into adjacent organ

N1 Perirectal nodes

N2  Unilateral internal iliac or inguinal lymph nodes

N3  N1 and N2, or bilateral N2.

M1 diatant metastases

Stage I  T1N0M0

Stage II T2-3 N0M0

Stage IIIa T1-3N1M0, T40M0

Stage IIIb T4N1M0, anyT N2-3 M0

Stage IV  M1

Treatment is wide local excision for small, well-differentiated, localized tumors confined to submucosa.  All others receive Nigro protocol. Historically, anal canal cancers were treated with APR but results were poor: 50% recurrence rates, 5-yr survival 24-62%.   In 1970s, sensitivity to chemoXRT established.

NIGRO protocol:

chemoradiation of 30Gy XRT of tumor, pelvic, and inguinal nodes from day 1 to 21, plus 5FU 1000mg/m^2 days 1-4 and 28-31 plus mitomycin C 15mg/m^2 on day1

If grossly disease disappears, no further treatment is necessary.  LNs treated as well regardless of status, outcomes as good as formal LAN. Repeat Biopsy at 6wks. If pos,

perform APR 4-6weeks after completion of radiation therapy OR repeat chemo (first line choice).  Complete response >90%.  5yr sur 85%.

Surveillance:

Most recurrences are locoregionally. If nodal recurrence, treat with chemoXRT.

anoscopy  q3mos x 2years, then q6mos

PE            q3mos x 2years, then q6mos

CT, LFTs, EUS: surveillance debatable.

ANAL MARGIN LESIONS

BASAL CELL CARCINOMA

Rare. Local excision.

BOWEN DISEASE

SSx: discrete scaly, crusty, or moist plaques surrounding the anus.  Diagnose with skin biopsy.  Treat with wide local excsion.

PERIANAL PAGET’S DISEASE

Rare intraepidermal neoplasm of apocrine glands.  Long preinvasive phase.  PE reveals scaly or red plaque.  Dx with biopsy.  Workup with full colonoscopy because 50% incidence of synchronous adenocarcinoma.  Rx with wide local excision.  Negative margins a must.  If underlying carcinoma, APR is required.

SQUAMOUS CELL CARCINOMA

Rare.  Less aggressive than SCCs of the anal canal.  Treat with local excision, not Nigro protocol.  Metastasizes to inguinal LNs.

BUSCHKE-LOWENSTEIN TUMOR – giant condyloma acuminatum.  Tend to erode into adjacent sturctures.  Local excision.  Consider chemoXRT for larger lesions.

Anal cancer: Multiple choice question
[copy and paste]
Multiple choice question

A 57 year old woman sees blood on the toilet paper. Her doctor notes the presence of an excoriated bleeding 2.8cm mass at the anus. Boipsy confirms the clinical suspicoin of anal cancer. In planning the management of a 2.8cm epidermoid carcinoma of the anus, which of the following is the best initial mangement strategy?

a. Abdominoperineal resection

b. Wide local resection with bilateral inguinal node dissection

c. Local radiation therapy

d. Systemic chemotherapy

e. Combined radiation therapy and chemotherapy

The aswer is e. (Greenfield, pp1131-1136)

Epidermoid cancers of the anal canal metastasize to inguinal nodes as well as to the perirectal and mesenteric nodes.

The results for local radical surgery have been disappointing.

Combined external radiation with synchronous chemotherapy (fluorouracil and mitomycin), also known as the Nigro protocol, has been used as the standard treatment of the disease, whereas radical surgical approaches are now generally reserved for treatment failures and recurrences.

Appendix addenocarcinoma: Multiple choice questions!

A 59 year old woman present with right lower quadrant pain, nausea, and vomiting. She undergoes an uncomplicated laparoscopic appendectomy. Postoperatively, the pathology reveals a 2.5cm mucinous adenocarcinoma with lymphatic invasion. Staging workup, including colonoscopy, chest x-ray, and CT can of the abdomen and pelvis, is negative. Which of the following is the best next step in her management?

a. No further intervention at this time; follow-up every 6 months for two years

b. Chemotherapy alone

c. Neoadjuvant chemotherapy followed by right hemicolectomy

d. Ileocecectomy

e. Right hemicolectoy

The answer is e. (Townsend, pp. 1395-1396; Brunicardi, p. 1134)

Patients with appendiceal adenocarcinoma, a rare neoplasm accounting for less than 0.5% of gastrointestinal tumors, should undergo formal right hemicolectomy. Often affecting older patients, they may present with symptoms mimicking those of acute appendicitis. A thorough initial workup and follow-up are necessary because of the high rate of synchronous and metachronous tumors. Five-year survival is 55% but depends on the tumor stage.

Color resection: ?? prophylactic antibiotics?? Multiple choice questions!

Preoperative Preparation:

- ?? perioperative antibiotics

- ?? bowel prep

Multiple choice questions!

A patient with a nonobstructing carcinoma of the sigmoid colon is being prepared for elective resection. Which of the following reduces the risk of postoperative infectious complications?

a. A single preoperative parenteral dose of antibiotic effective against aerobes and anaerobes

b. Avoidance of oral antibiotics to prevent emergence of Clostridium difficile

c. Postoperative administration for 48 hours of parenteral antibiotics effective against aerobes and anaerobes

d. Postoperative administration of parenteral antibiotics effective against aerobes and anaerobes until the patient’s intravenous lines and all other drains are removed

e. Redosing of antibiotics in the operating room if the case lasts for more than 2 hours

The answer is a. (Townsend, pp 261-262)

The appropriate dosing and timing of antibiotic prophylaxis to prevent surgical site infections in an elective procedure is a single dose, no greater than 1 hour prior to the incision.

Additionally, most textbooks recommend use of an oral, nonabsorbable antibiotic regimen effective against aerobes and anaerobes in combination with a mechanical bowel preparation before elective colon resections.

There is no evidence to support the continuation of antibiotics for more than 12 hours after an elective operation has been completed, and this practice should be avoided to prevent increasing microbial drug resistance.

For complex, prolonged procedures, redosing of antibiotics may be appropriate during the procedure based on the drug’s half-life.

Broad-spectrum antibiotic coverage, including against anaerobic organisms, is required only in cases where such flora are anticipated, such as during colon resections; otherwise, cefazolin is the antibiotic of choice for cases requiring antibiotic prophylaxis.

Colectomy: Background

In all colectomies, the bowel is either reconnected afterward (which is called an anastomosis) or the surgeon creates an ostomy, an opening of the bowel on the abdominal wall, to allow the contents of the bowel to exit from the body.

Total colectomy / Proctocolectomy

Total colectomy / Proctocolectomy

A special variant of colectomy is total colectomy, which is also called proctocolectomy. This is most commonly a treatment considered for people with ulcerative colitis, either because of failure to respond to treatment or because of the cancer risk associated with the disease.

Sigmoid resection: Multiple choice case

Multiple choice question

A 52 year old woman undergoes a sigmoid resection with primary anastomosis for recurrent diverticulitis. She returns to the emergency room 10 days later with left flank pain and decreased urine output; laboratory examination is significant for a white blood cell (WBC) count of 20,000/mm3. She undergoes a CT scan that demonstrates new left hydronephrosis, but no evidence of an intraabdominal abscess. Which of the following is the most appropriate next step in management?

a. Intravenous pyelogram

b. Intravenous antibiotics and repeat CT in one week

c. Administration of intravenous methylene blue

d. No further management if urinalysis is negative for hematuria

e. Immediate reexploration

The answer is a. (Brunicardi, pp 175, 1606)

The patient should undergo an intravenous pyelogram for a suspected ureteral injury.

After gynecologic surgeries, colorectal surgery is the most common cause of iatrogenic ureteral injuries.

Intraoperatively, intravenous administration of methylene blue or indigocyanine green may facilitate identification of an injury.

However, delay in diagnosis is common, and patients may present with flank pain, fevers, and signs of sepsis, ileus, or decreased urine output.

CT scan may demonstrate hydronephrosis or a fluid collection (urinoma).

Initial diagnosis and management should include urinalysis, although hematuria may not always be present; percutaneous nephrostomy tube or retrograde ureteral catheterization; percutaneous drainage of fluid collections; and identification of the location of ureteral injury.

Surgical management should be delayed if diagnosis is late (10 to 14 days), and operative strategy is dependent on the location of the injury.

Diagnostic imaging such as a pyelogram or nuclear medicine scan may be helpful to identify the site of injury.

Total colectomy with diverting ileostomy: Multiple choice case

Multiple choice case

A 60 y/o woman with no previous medical problems undergoes a total colectomy with diverting ileostomy for a cecal perforation secondary to a sigmoid stricture. Postoperatively, she has 2L of ileostomy output per day. Her heart rate is 110 beats per minute, her respiratory rate is 16 breaths per minute, and her oxygen saturation is 98% on 2L NC. Her laboratory values on postoperative day 6 are as follows: Na 128, K 3.0, Cl 102, and HCO3 20. Which of the following statements is true?

a. Her laboratory abnormalities are most likely secondary to a Type IV renal tubular acidosis

b. Her laboratory abnormalities are most likely compensatory for a primary respiratory problem

c. She should be treated with fluid replacement and empiric treatment with oral Vancomycin

d. She should be treated with fluid replacement and stool-bulking agents

e. She should undergo immediate dialysis

The answer is d. (Brunicardi, pp. 50-51)

The patient has a non-gap metabolic acidosis, [Na -(Cl + HCO3)] = 128-(102+20)= 6

sedondary to high output from her ileostomy with gastrointestinal losses of bicarbonate.

This should be managed with fluid replacement and stool-bulking agents.

The ionic composition of small-bowl fluid is Na 140, K 5.0, Cl 104, and HCO3 30.

Patients with large ileostomy outputs are at risk for dehydration with accompanying hyponaremia, hypokalemia, and non-anion-gap metabolic acidosis.

While renal tubular acidosis (RTA) can be associated with a non-anion-gap metabolic acidosis, type IV RTAs are typically associated with hyperkalemia.

Renal failure can result in an anion-gap, uremic acidosis and hyperkalemia, both of which may be indications for dialysis.

Finaly, while C. difficile colitis should be considered in postoperative patients with diarrhea, C. difficile enteritis is less common in a non-immunocomproised host, and Vancomycin is reserved for failures to metronidazole treatment.

Multiple choice questions

A 62 year old man has been diagnosed by endoscopic biopsy as having a sigmoid colon cancer. He is otherwise healthy and presents to your office for preoperative consultation. He asks a number of questions regarding removal of a portion of his colon. Which of the following statements is true regarding the effects of colon resection?

a. Net absorption of water by the rectum has been demonstrated in humans

b. Patients who undergo major colon resections suffer little change in their bowel habits following operation

c. The left colon is better adapted for water absorption than the right colon

d. The right colon is better adapted for electrolyte absorption than the left colon

e. The role of the ileocecal valve in normal fluid homeostasis is well established

The answer is b. (Greenfield, pp1063-1069)

Because the reserve capacity of the colon for water absorption greatly exceeds the normal requirements for maintaining stable bowel function, patients may undergo resection of a large fraction of the colon and suffer little change in bowel habits.

Neither the right nor the left colon appears to be a site of preferential water and electrolyte absorption, nor does the ileocecal valve play a noticeable role in fluid homeostasis.

However, in diseases characterized by increased fluid secretion of the small bowel, the colon is more likely to be overwhelmed by the absorptive demand following partial colectomy than in the intact state

The rectum does not appear to play a role in fluid absorption.
