>80% of cases have successful reduction (Conrmed by resolution of the mass and reux of air into the proximal ileum). Recurrence rates are 11% and usually recur within the rst 24h.
• First recurrence is managed with repeat enema.
• Further recurrence is an indication for surgery.
• Operative Management: – Indications to consider surgery: peritonitis, hemody-
namic instability, complete small bowel obstruction, small bowel location, failure of hydrostatic complete reduction, history of several recurrences.
– Laparoscopy or primary exploratory laparotomy
(transverse incision in pediatrics).
– Reduce by squeezing the mass retrograde from distal
to proximal until reduced. Do NOT pull out the intussusceptum.
– Bowel resection is indicated when the intussusception
cannot be reduced, bowel is not viable/viability is uncertain, or a led point is identied. Ileocolectomy w/ primary anastomosis is usually performed.

Common Curveballs

• Patient becomes peritoneal during air/barium enema
attempts.
• Multiple recurrences occur after successful reduction.
• Patient is an adult (concern that malignancy is the
problem).
• Patient is a post-bariatric surgery patient and the intus-
susception is at the jejunojejunostomy.
• Other causes are found to be the cause: polyps, the appen-
dix, intestinal neoplasm, submucosal hemorrhage associ­ated with Henoch-Schönlein purpura, a foreign body is
found, ectopic pancreatic or gastric tissue is found in the pathology specimen.
• This is a Meckel’s diverticulum (remember the rules of 2’s: 2% of the population, within 2feet of the IC valve, 2 inches in length, two types of mucosa (gastric/ pancreatic).

Clean Kills

• Taking a patient with peritonitis for enema reduction.
• Patient starts having signicant bloody stools.
• Not proceeding to surgery for hemodynamic instability/ peritonitis.
• Not resecting a clear lead point.

Summary

Children with intussusception can often be reduced with­out surgical intervention and are commonly due to benign causes like swollen lymphoid tissue from recent viral infection. Children are less likely to have a lead point but can be found in up to 12% in pediatric patients and this risk increases with age. In adults intussusception is more likely to require surgical resection as it is more commonly due to a pathologic lead point of some kind. Always proceed to surgery in any patient, regardless of age, who demonstrates peritonitis or hemodynamic instability.

Lower Gastrointestinal Hemorrhage

DanicaN.Giugliano
27

Lower Gastrointestinal Hemorrhage

• Bleeding source originates distal to the ligament of Treitz
• Common cause of hospital admissions
• Often stops spontaneously before denitive diagnosis can be made
• Etiologies:
– Hemorrhoidal bleeding and ssure (5–20%) usually
cause minor bleeding over time and unlikely to cause massive lower GI hemorrhage
– Diverticulosis coli bleeding (30–65%) can occur in
15% of patients with diverticulosis
Risk factors include NSAID use, hypertension, and anticoagulant use Up to 80% of these types of bleeds spontaneously stop
– Angioectasia (3–15%) is a submucosal dilated, tortu-
ous vascular abnormality
– Ischemic colitis (10%) is usually less severe bleeding
than diverticular bleeding or angioectasia bleeding
Splenic exure (Grifths’ point) and rectosigmoid colon (Sudeck’s point) are “watershed” regions and can cause ischemic colitis Cramping abdominal pain with abdominal tender­ness on the left side of the abdomen can accompany bleeding Symptoms usually resolve in 2–3days unless acute mesenteric vascular occlusion or non-occlusive mesenteric ischemia (NOMI) has occurred
– Neoplasm (<10%) can cause ulceration and bleeding
A 70-year-old man presents to the emergency department
with 2hours of bright red blood per rectum that is continu-

ous. He feels weak and dizzy and reports this has not hap­pened previously. He takes Eliquis for a history of atrial brillation.
What do you do next?
• Assessment of patient stability and placement of two large-bore intravenous lines
• Rapid volume resuscitation with crystalloid uid
• Get laboratory studies and order blood products
– Keep hemoglobin >9–10 if cardiac history, otherwise
>7
– May need concurrent administration of platelets and
fresh frozen plasma
• Continuous monitoring of vital signs and foley placement to monitor urine output
• History questions include duration of bleeding, frequency, color of blood, as well as surgical history and radiation history
• Physical examination include abdominal exam and digital rectal exam with anoscopic exam if possible
• Place an NG tube and assess for blood or bile. If blood clot or coffee grounds, obtain upper endoscopy
– Clear uid is indeterminate
If the patient stabilizes and bleeding stops over the next
24h, what do you do next?
• Colonoscopy

Evaluation

• Colonoscopy
– If bleeding is self-limiting, administer mechanical
bowel preparation prior to colonoscopy
– Advantageous since diagnosis and therapeutic inter-
ventions can be performed
Therapeutic interventions include clipping, band ligation, injection of epinephrine or saline, monop-

olar or bipolar electrocautery, laser coagulation or argon plasma coagulation (APC)
• Radionuclide Scintigraphy – Tc99-RBC scan cans how active hemorrhage with
high sensitivity and slow washout of tracer – Detection of bleeding as slow as 0.04–0.05cc/min – Screening test prior to proceeding with mesenteric
angiogram
• Computed Tomography Angiography (CTA) – Usually used prior to Tc99-RBC scan – Detection of bleeding as slow as 0.03cc/min – Sensitivity is 91–92% when bleeding is active or
45–47% when bleeding is intermittent
– Advantage of also being able to identify coexisting
pathology but disadvantage of small risk of nephropathy
– A positive scan should prompt angiographic emboliza-
tion or surgical resection for massive hemorrhage
• Diagnostic Angiography – Requires bleeding rate of 0.5–1.5cc/min – Provocative angiography can be used for recurrent
intermittent lower GI bleeding
– Risks include bleeding, access complications, throm-
boembolic events, contrast-induced nephropathy
What if the patient has recurrent bleeding and cta is posi­tive for active bleeding and the splenic exure? what do you do now?
• Therapeutic Angiography
– Microcoils, polyvinyl alcohol particles, and Gelfoam
can be used
– Cessation of active bleeding seen in up to 90% of
patients
– Complications include transmural ischemia and
colonic stricture formation

Surgery

• Emergency surgery without localization occurs in less
than 5% of patients
• Indicated if patient is hemodynamically unstable with
refractory, ongoing bleeding, if therapeutic efforts are
unsuccessful or not feasible despite localization, or if
massive transfusion requirements (6 units of PRBC in
24h period)
• Exploratory laparotomy
– Examine small bowel for Meckel’s diverticulum and
for masses
– Transilluminate small bowel for angioectasia
– Intraoperative colonoscopy and/or push enteroscopy
can be performed if patient is stable
– If no obvious source from stomach, small bowel, or
anorectum, perform a total abdominal colectomy with end ileostomy
• Rebleeding after TAC is <5%
• If bleeding site is localized, a targeted segmental resec­tion with or without an anastomosis can be performed
– Rebleeding rate is 4–10%

Clean Kills

• Not stabilizing patient with two large bore IVs and IV uids
• Not ruling out upper GI bleeding with NG tube lavage
• Performing segmental resection without localization of bleed

Bonus Points

• Other etiologies of lower intestinal hemorrhage:
– Post-polypectomy hemorrhage – Inammatory bowel disease – NSAIDs – Infectious colitides due to bacterial infection
(Campylobacter, Salmonella, Shigella, Escherichia
coli, Yersinia) – Radiation injury – Rectal ulceration – Dieulafoy’s lesions
Words ofWisdom
• The management of lower gastrointestinal hemorrhage is important to understand, as it is a common condition with many etiologies. Be sure to hemodynamically stabilize the patient and use diagnostic testing to try to localize the source of bleeding. Surgery is reserved for patients who either have localized bleeding and therapeutic angiogra­phy is not successful or able to be performed, or for patients who are unstable despite resuscitation.

Peri-Rectal Abscess

HannahSoeld andDanicaN.Giugliano
28

Perianal Abscess

• Most common, around 60% of anorectal abscesses. They are supercial and do not involve the external anal sphincter.

Ischioanal Abscess

• Occur in the ischiorectal fossa (Borders: inferior­perineum, superior- levator ani, lateral- ischium and obtu­rator internus, medial- external sphincter)

Intersphincteric Abscess

• Occur between the internal and external sphincters

Supralevator Abscess

• Occur superior to the levator ani

Horseshoe Abscess

• Abscess in any space that crosses the midline
A 25-year-old male presents with perianal pain for the
past 3days. He denies fevers or chills. On exam, you see a

2.5cm erythematous, uctuant, and tender area in the right posterolateral anal area. How do you proceed?
• Obtain further medical history, need to ask about fecal continence, history or risk factors for Crohn’s disease, and prior abscesses.
The patient has no fecal incontinence, denies prior
abscesses, and no symptoms of Crohn’s disease. What treat­ment would you offer this patient?
• Incision and drainage of the abscess under local anesthe­sia, if the patient can tolerate it. Otherwise, the patient will need operative debridement. Incision (elliptical or cruci­ate) should be made as close as possible to the anal verge, and this limits length of stula tract if it were to form.
How should you counsel the patient prior to surgery?
• Risk of fecal incontinence (8–50%), risk of recurrence (~50%), risk of stula formation (~50%)
Does the patient need antibiotics? What if the patient was
experiencing systemic symptoms?
• The patient does not need antibiotics given the absence of systemic symptoms; drainage of the abscess is sufcient treatment. Antibiotics are warranted when systemic symp­toms are present or the patient is immunocompromised.
Three months later, he returns with a recurrence of the
abscess. How do you manage this patient?
• This patient likely has a stula. The patient needs an exam under anesthesia to assess the presence or absence of a stula tract and, if found, surgical treatment of the stula.
• MRI pelvis can be used preoperatively to dene anatomic relationships of the stula if stula is recurrent or if mul­tiple external openings.

H. Soeld and D. N. Giugliano
How would management change if there was extension of
the abscess into the contralateral side?
• This is a horseshoe abscess and requires a counter inci­sion during the drainage procedure. A seton can also be used. The patient should be counseled that horseshoe abscesses carry a high risk of recurrence.
Intersphincteric Fistula (Parks Type 1)
• Involve a portion of the internal sphincter, course through the intersphincteric plane, external opening in perianal skin
Transsphincteric Fistula (Parks Type 2)
• Traverse both internal and external sphincters
Suprasphincteric Fistula (Parks Type 3)
• Track through anal crypt, encircles the entire external sphincter
Extrasphincteric Fistula (Parks Type 4)
• Least common type, not cryptoglandular in origin, encir­cle both internal and external sphincters
• This is a simple stula as it involves no external sphincter. Treatment would be primary stulotomy. This is accom­plished by unroong the entire length of the stula while a probe is in place.
How would you proceed if the stula was transsphincteric?
• Transsphincteric stulas involve both the internal and external sphincters and thus cannot be treated with stu­lotomy due to high risk of incontinence. There are two options, a seton can be placed to attempt to brose the tract, or a LIFT (ligation of the intersphincteric stula tract) procedure can be performed. During a LIFT proce­dure, the stula tract between the internal and external sphincters is identied and ligated.
• An Endorectal advancement ap can be used for high transsphincteric or suprasphincteric stulas. This includes debridement of the stula tract with mobilization of a mucosal ap and coverage of the internal opening with suture.
The patient returns 4months later with a new stula on
the left side. How do you proceed?
Further Classication
• Simple: managed through stulotomy without risk of fecal incontinence, involving minimal to no external sphincter.
• Complex: involve more than 30% of the external sphinc­ter, have multiple tracts, or are caused by Crohn’s disease, malignancy, or radiation; these cannot be managed by stulotomy.
Alternate Scenario A 25-year-old male with history of two prior anorectal abscesses presents with intermittent drain­age near his anus. How do you proceed?
• Obtain focused history of risk factors for anorectal abscesses and stulas including Crohn’s disease, hidrad­enitis suppurativa, pelvic sepsis, trauma, or malignancy.
• Perform an anorectal examination including a digital rec­tal exam.
The patient’s history is negative for risk factors. On exam-
ination you notice a small external opening 2cm lateral to the anal verge on the left side, when pressed a scant amount of serous uid is expressed. What is your next step?
• Proceed to an examination under anesthesia to assess the type and extent of stula.
In the operating room, the stula can be probed to its
internal opening, and there is partial internal sphincter involvement. How do you proceed?
• A new stula on the opposite side raises suspicion for Crohn’s disease. Patients should be referred to a gastroen­terologist for Crohn’s disease evaluation including a colo­noscopy. Crohn’s disease stulas, even if simple, should not be treated with primary stulotomies. The safest approach to management while pursuing diagnostic workup is placing a seton in the stula tract. More deni­tive stula management can be discussed with the patient once a stable Crohn’s disease treatment regimen is established.
What if a simple stula was observed in a 65-year-old
female with poor fecal continence at baseline?
• Primary fistulotomy is NOT recommended for patients if a patient has a history of fecal inconti­nence. Surgical options are seton placement or a LIFT procedure.

Clean Kills

• Not asking about history or symptoms of Crohn’s disease
• Offering a primary stulotomy to a Crohn’s patient
• Performing a primary stulotomy for an intersphincteric stula
• Not initiating antibiotics in a patient with systemic symptoms
• Not performing a counter incision for a horseshoe abscess
28 Peri-Rectal Abscess
85

Bonus Points

• Adipose-derived stem cells is a new technique to treat complex anal stulas, mostly in patients with Crohn’s dis­ease. Research with multicenter randomized controlled trials using this technique is currently underway.
Words ofWisdom
• The management of peri-rectal abscesses requires thor­ough knowledge of the pelvic oor anatomy and spaces occupying the anus. Draining these abscesses can be done
in the ofce or in the operating room. Necrotizing infec­tions should go immediately to the operating room and require aggressive surgical debridement. Fistulas occur in 50% of patients with perianal abscesses, and are managed based on their location in relation to the anal sphincter complex.

Rectal Cancer

MatthewC.Moccia andDanicaN.Giugliano
29
A 61-year-old man presents with occasional bright red blood per rectum. He had a Ct performed in the ER that is concerning for the presence of a rectal mass. He is hemodynamically stable and otherwise asymptomatic. How should you proceed?
• As with the workup of nearly every other disease process, the rst step includes a complete history and physical examination.
• Ask about changes in bowel habits (especially any obstructive symptoms), fecal continence history, environ­mental factors, history of colonoscopy, and family history of gastrointestinal, biliopancreatic, and gynecologic malignancies.
• Physical exam should almost always include a rectal exam.
• Standard laboratory tests should be ordered, with the addition of a CEA.
• A colonoscopy should be used to assess tumor location and characteristics and obtain biopsy for pathology review.
• Once the presence of a tumor is conrmed, obtain staging studies including a CT chest/abdomen/pelvis and rectal cancer protocol MRI (standard of care).
• If MRI is not available obtain endorectal ultrasound.
• Up to 98% of rectal cancers are adenocarcinoma, but just be aware that other histological types can occur (carci­noids, sarcomas, lymphomas, etc.).
• If an obstructing or near obstructing tumor is seen, this should prompt discussion for fecal diversion and decom­pression with a loop colostomy (must be distal to the ileo­cecal valve).

A 61-year-old man was recently in the ER and was diag-
nosed with a non-obstructing rectal adenocarcinoma. He is anxious to know his treatment options. What do you tell him?
• The management of rectal cancer has evolved signi­cantly since the turn of the millennium. Any patient with unresectable disease on presentation should be discussed at a multidisciplinary management meeting including sur­gical, medical, and radiation oncologists.
• For resectable disease, certain T1 tumors can be removed transanally via a variety of methods (transanal excision, transanal minimally invasive surgery, transanal endo­scopic microsurgery, endoscopic submucosal dissection), as long as there is no nodal involvement seen on staging examinations.
• For higher stage tumors or those not amenable to trans­anal removal, surgical technique is based mainly on tumor location within the rectum and the presence or absence of sphincter involvement.
– Surgical options include low anterior resection (LAR),
resection with coloanal anastomosis, or abdominoperi­neal resection (APR).
– The goal is to achieve a total mesorectal excision
(TME).
– High ligation of the inferior mesenteric artery should
be achieved and a minimum of 12 lymph nodes should also be removed.
– The involved segment should be completely removed,
ideally with 5-cm margins. However, a distal negative margin of 1cm or less is acceptable in patients under­going sphincter-preserving surgery.
– Any local structures or organs invaded by the primary
tumor should be removed en bloc.
• Patients with isolated hepatic metastases should be offered surgical resection of the metastases when feasible.
– If the hepatic metastases are unresectable, other treat-
ment options include radiofrequency ablation, chemo­embolization, and brachytherapy.

Total Neoadjuvant Therapy (TNT)

• TNT is administering all systemic chemotherapy and radiation therapy before surgery.
• TNT was developed and applied to a number of new mul­timodal treatment strategies for locally advanced rectal cancer that administer both radiation and systemic ther­apy before surgical resection. These strategies can vary substantially in their radiation dosages and fractionations, chemotherapy options and sequencing of modalities, but what they have in common is the administration of both radiation and full systemic chemotherapy (as opposed to lower radio-sensitizing chemotherapy doses) in the neo­adjuvant setting, before surgery.
• The sequence of TNT regimens can be classied as induc­tion chemotherapy (chemotherapy rst) or consolidation chemotherapy (radiation rst).
• Landmark randomized controlled trials (RAPIDO, PRODIGE-23), TNT has moved to the forefront of locally advanced rectal cancer treatment and is considered a stan­dard option in selected patients.
• TNT should be considered (although not necessarily always given) for all locally advanced rectal cancers.
• Indications for TNT include clinical T4 disease or close or involved circumferential resection margin, N2, lateral pelvic node involvement or extramural vascular invasion.
• TNT is associated with higher rates of pathologic com­plete response, better downstaging and downsizing, and improved chemotherapy completion rates over non-TNT approaches.
A 61-year-old man has recently nished treatment for his
stage II rectal adenocarcinoma. He sees you in the ofce and asks how frequently he should be seeing you in the future. What do you tell him?
between colonoscopies is 5years. Of note, proctoscopy should be performed every 6months for 3–5years if the patient underwent local instead of radical excision.
A 25-year-old patient presents to your ofce after being referred for the presence of rectal cancer. What special con­sideration is warranted in this patient?
• The diagnosis of rectal cancer in any patient younger than
45 should prompt consideration for genetic testing. There
are a few genetic syndromes with which you should be
aware.
– Familial adenomatous polyposis (FAP) is an autoso-
mal dominant disorder caused by a mutation in the adenomatous polyposis coli (APC) gene
– Lynch syndrome/hereditary nonpolyposis colorectal
cancer (HNPCC) is an autosomal dominant disorder affecting DNA mismatch repair (MMR) genes
– Peutz-Jeghers syndrome (PJS) is an autosomal domi-
nant disorder affecting the serine-threonine-kinase tumor suppressor (STK11) gene
– MUTYH-associated polyposis (MAP) is an autosomal
recessive disorder resulting from biallelic mutations in the MUTYH gene

Bonus Points

• Amsterdam criteria 3-2-1 rule: three relatives with
colorectal (one is a rst degree relative) cancer, two con-
secutive generations affected, one relative diagnosed
before age 50, FAP excluded
• Pathology specimens should undergo IHC for MMR pro-
tein expression and PCR for MSI analysis
• Surveillance is recommended for stage 1 disease with high-risk features, stage 2 and 3 disease, and stage 4 dis­ease when isolated metastases are resected for cure.
• An ofce visit with CEA is recommended every 3–6months for 2years, then every 6months until 5years.
• CT chest/abdomen/pelvis should be obtained every year for 5years.
• A colonoscopy needs to be completed 1year after sur­gery, unless the entire colon was not visualized preopera­tively, in which case colonoscopy should be performed 3–6months after surgery. Subsequent colonoscopies will be performed after either 1, or 3years, depending on the ndings from the colonoscopy. The longest time period patients with a history of rectal cancer should have
Words ofWisdom
• Rectal cancer can present without any symptoms, or with subtle symptoms such as change in bowel habits and/or rectal bleeding. Proper diagnosis and preoperative staging are essential for proper treatment. TNT has become increasingly common for more advanced tumors. The types of TNT have been evolving and being up-to-date with randomized controlled studies is important for future management of these patients. In combination with pre­operative treatment, proper surgical excision is also essential for the best outcomes. Performing a TME with negative margins is important for reducing the rate of tumor recurrence.
