Objectives 1.Office evaluation of rectal pain and bleeding. Not all rectal complaints are due to hemorrhoids. 2.Signs and symptoms of hemorrhoids and anal fissure. 3.Etiology and epidemiology of hemorrhoids. 4.Treatment options. 5.Colorectal Cancer Screening.
Presenting Ano-rectal complaints 1.Pain-50% 2.Bleeding-40% 3.Swelling-25% 4.Pruritus-24% 5.Associated with pregnancy, constipation, diarrhea, stress, certain foods, alcohol. Hemorrhoids, anal abscess and fissures, pruritus ani, colorectal cancer, or proctitis.
Hemorrhoids by the numbers 1.Over half the population will have some hemorrhoidal symptoms by age 50 and the incidence peaks between Men and women effected equally but men are more likely to seek treatment million Americans have active hemorrhoids and as many as 5 million seek medical help each year. 3. We spend over 250 million dollars each year on hemorrhoid products. 1.5 million prescriptions. 4. More than 120,000 surgical hemorrhoidectomies are done each year. Most are unnecessary million colonoscopies are done each year.
What are hemorrhoids? Internal hemorrhoids are dilated blood vessels and the surrounding tissue above the dentate line. Covered by mucosa. Direct arteriovenous communications of the terminal branches of the superior rectal and superior hemorrhoidal arteries and to a lesser extent the inferior and middle hemorrhoidal arteries. They usually form three anal cushions (right anterior, right posterior, left lateral) that help maintain continence. Symptoms come from dilation of the blood vessels and increased friability, weakening of the surrounding tissue and attachment to rectal wall, injury from passing stool, and prolapse. External hemorrhoids are below the dentate line and are covered with modified squamous epithelium and richly innervated with somatic nerves. Hemorrhoids tend to enlarge over time and prolapse.
Anatomy of hemorrhoids
Grades The severity is graded by the degree of prolapse Grade 1 -no prolapse and cause painless bleeding. Grade 2 - prolapse on defecation, go back spontaneously. Seen on straining. Grade 3 - prolapse and have to be pushed back leading to bleeding and aching pain. Grade 4 - Can’t be pushed back leading to mucoid discharge, bleeding, pain, necrosis.
Prolapsed Internal Hemorrhoids
What causes hemorrhoids? Lack of soluble fiber and enough water in the diet, straining, and sitting longer than 2 minutes on the toilet which promotes prolapse of the anal cushions. Hemorrhoids may be inherited, but it may only be the behaviors and diet habits that are passed along. Failure to eat breakfast. Increase in abdominal pressure e.g. pregnancy, obesity, pelvic tumors, lifting, sitting, coughing, constipation, diarrhea, anal intercourse, aging. Correlation with decreased connective tissue strength as seen in hernias and genitourinary prolapse. Hemorrhoids can be exacerbated by excessive cleaning, rubbing, steroids, and hemorrhoid creams. Enlargement comes from the dragging of the hemorrhoids downward, weakened supporting tissue. Elevated sphincter tone increases straining.
Risk Factors 1.Past history of hemorrhoid symptoms or anal fissure 2.Age Heavy lifting, prolonged sitting 4.Constipation/Diarrhea 5.Pregnancy 6.Failure to eat breakfeast. 7.Diet-Spicy food, fats, alcohol, smoking, low water intake. 8.Obesity 9.Spinal cord injuries 10.Increased sphincter tone
Hemorrhoid Prevention 1.Add fiber to prevent constipation and diarrhea 2.Drink lots of water 3.Do not ignore the urge to go 4.Do not strain 5.Limit time on commode to two minutes 6.Remove the library from the bathroom 7.Avoid obesity
Typical Hemorrhoid Symptoms Internal Hemorrhoids 1.chronic intermittent bright red bleeding with bowel movements. On tissue, in commode, or streaked on stool surface. 2.Feeling of fullness, swelling, extra tissue, incomplete BM. 3.Irritation or itching from seepage of mucus, fecal soiling or dermatitis from hemorrhoid creams causes rash. 4.Pain may occur with prolapse, associated external hemorrhoids or anal fissure. Visceral nerves above dentate line sense pressure not pain. External Hemorrhoids 1.Rectal pain from stimulation of somatic nerves of anal skin. 2.Bulge of tissue on anal skin 3.Blood on toilet tissue. 4.Thrombosis leading to a hard painful lump. 5.Skin tags left over after dilated external hemorrhoids, hemorrhoidectomy, or resolved thrombosis. Can trap stool and cause dermatitis and pruritus.
Diagnosis of Hemorrhoids 1. History and physical exam including perianal inspection and digital rectal exam. Done in left lateral position. Ask patient to strain. Side viewing anoscopy. Significant pain suggests thrombosis, fissure, spasm, proctitis, abscess. 2. Sigmoidoscopy-rigid vs. flexible to rule out tumors of lower colon and IBD (dull mucosa, absent vascular pattern, friable bleeding mucosa, ulcers, and pseudopolyps. 3. Manometry/endorectal ultrasound-incontinence 4. Colonoscopy for persistent bleeding, polyps, IBD 5. Anal complaints are not always hemorrhoids.

Bloody Stools-Lower GI Hemorrhage in Adults Melena-Black Tarry stools due to digested blood from upper digestive tract, esophagus, stomach, and jejunum. Esophagitis, varices, gastritis, gastric ulcer, peptic ulcer, angiodysplasia, jejunal diverticulum. Rarely from a slow bleeding right colon lesion. Black licorice, lead, iron, bismuth medicines-Pepto Bismol can also cause black stools. Hematochezia-Red or maroon-colored stools frequently foul smelling. Diverticulosis, angiodysplasia, inflammatory bowel disease, anorectal disease such as hemorrhoids, anal fissure, fistula in ano, colorectal polyps or cancer, ischemic colitis, infectious colitis, radiation enteritis, coagulopathy, aortoenteric fistula, post- polypectomy, post-hemorrhoidectomy, hemobilia, or massive UGI bleeding. Massive lower GI bleeding causes shock and may require transfusion. Diverticulosis is the most common cause of major lower GI bleeding. Blood mixed with stool, shorter duration of sx, and more episodes per month are more common with cancer, polyps, IBD when compared to hemorrhoids. Rectal Bleeding from Hemorrhoids or Anal Fissure-Blood on tissue, on outside of formed stool, or drips into commode after bowel movement. Blood is bright red in color. Typically mild and intermittent but occasionally massive. Hemorrhoids are the most common cause of chronic intermittent minor or non-massive lower GI bleeding associated with bowel movements.
Medical Management of Hemorrhoids 1.Add 15 grams of fiber and drink 6-8 glasses of water each day. Avoid constipation and diarrhea. Rx IBS. 2.Avoid straining and prolonged sitting on commode. Remove reading materials from bathroom. Weight loss. Moderate exercise but avoid heavy lifting and strenuous exercise. 3.Tub baths with warm water 4.Keep area clean with warm water and avoid scented or colored tissue 5.Lubricating ointment-Vaseline 6.Generic 2.5% HC + 1% Pramoxine HCL-$10 limit to two weeks. 7.Long airline flights aggravate hemorrhoids. 8.Micronized, purified flavonoid fraction. Not approved by FDA 9.Hemorrhoid products can reduce symptoms of itching or minor discomfort but will not help significant bleeding, prolapse, or cure the problem.
Fiber 1. Trials of fiber show a consistent beneficial effect for symptoms and bleeding in the treatment of symptomatic hemorrhoids. Fiber for the treatment of hemorrhoids complication: a systematic review and meta-analysis. Am J Gastroenterol Jan;101(1): About a 50% decrease in symptoms.
Fiber in food A healthy diet should include 30 grams of fiber. The typical western diet contains 15 grams. Low fiber diets can cause smaller harder stools leading to hemorrhoids and diverticulosis. Fiber is an indigestible polysaccharides found in plant cells. Soluble fibers (Gums, Pectin, Hemicelluloses) dissolve in water and form a thick jelly like substance, where insoluble fibers (Cellulose and Lignin) do not. Soluble fiber improves stool bulk and water content and is the important component for proper function of the colon. Also stays in stomach longer and reduces glycemic load and cholesterol levels. Bulkier stools preventing each end of lengths of the colon closing off with the normal segmentation movement of the colon preventing rise in colonic pressure and results in less cramps and lower rectal pressure on vessels. Try a variety of fibers, increase slowly, and wait up to six weeks to see benefit.
Low Fiber Diet Fiber has been removed during the refining of food particularly bread and starches. The typical diet has 15 grams of fiber. Low fiber contributes to obesity and disturbance of the enteroinsular axis and in many the onset of NIDDM. Adding fiber slows digestion, lowers cholesterol and blood sugar, decreases risk of cardiovascular disease, and may help reduce the risk of CRC.

Complications of Hemorrhoids Bleeding - can be severe but rarely life threatening unless the patient is taking meds like Warfarin. Severe Pain-anal fissure with spasm of the sphincter is often associated with hemorrhoids and the hemorrhoids can thrombose (clot), prolapse, or incarcerate (become trapped) and then are very painful and can become infected or gangrenous.
Hemorrhoid Procedures 1.Hemorrhoidectomy: Milligan-Morgan(open), Ferguson(closed). 1-2 days in hospital. Anesthesia required. Effective but more expense, pain, complications, and disability compared to office treatments. Its reputation causes many to avoid effective Rx and to buy ineffective hemorrhoid creams. 2.PPH-Procedure for Prolapse and Hemorrhoids. Introduced in Lower pain than above but may have higher recurrence rate and similar complication rate. Learning curve. Perforations, stenosis, bleeding, or chronic pain may occur. 3.Rubber Band Ligation causes ischemic necrosis and scarring, which results in shrinkage of tissue and fixation to rectal wall. Office procedure with minimal pain and complications. Low recurrence rate which can be Rx with rebanding. 4.IRC-infrared coagulation requires 5-7 Rx, is more expensive than banding, higher recurrence rate, and may make external disease worse. Coagulates and scleroses tissue with heat. Less painful than old banders but more painful than CRH bander. 5.Sclerotherapy-Phenol or vegetable oil, urea hydrochloride or hypertonic salt injected into base. Out of favor 2 nd to complications and high recurrence rate. 6.Bipolar diathermy-Coagulates and fibroses with heat. 7.Direct-current electrotherapy-Coagulates and fibroses with heat. 8.Doppler ligation-more expensive and no proven advantage over banding. 9.Cryosurgery and anal stretch no longer recommended because of complications
Procedure for Prolapsing Hemorrhoids - PPH 1.Learning curve may contribute to complications. 2.4% bleeding. Staple line bleeding to uncontrollable bleeding. 3.Reoperation % 4.Pain with BM or Urge to defecate for several weeks. 5-14% 5.Pain, anal fissure, missed polyps 6.Recurrence 7.Perforations, Stenosis, Retained staples 8.Pelvic Sepsis, Urinary retention 9.Rectovaginal fistula, incontinence 10.Inflammatory polyps causing late bleeding-11 % Stapled hemorrhoidectomy offers less pain than traditional hemorrhoidectomy but leaves persistent tags, higher recurrence rate, and rarely severe complications not usually seen. PPH33-03 is a new stapler reported to have fewer complications.

CRH-O’Regan Ligation System Barron report on 150 patients banded in office Dr. Patrick O’Regan develops a disposable ligation system featuring gentle suction instead of metal grasper Dr. Iain Cleator, Professor Emeritus of Surgery, University of British Columbia, opens Cleator Clinic Dr. Cleator reports on 5,424 bandings on 1,852 patients. Complication rate of.3%, 99.1% effective, 2 year recurrence rate of 5%. No pain medication and immediate return to normal activities CRH opens offices in Chicago, Atlanta, Las Vegas, San Francisco, Los Angeles Ligator has now been proven safe and reliable in over 15,000 applications. 7. Banding normalized the size of hemorrhoidal cushions. 8. Inflammation reattaches tissue to surrounding muscles. 8. External disease improves but skin tags may be left behind.
Who can be banded 1.All grades of hemorrhoids can be banded. Grade I may respond to conservative measures but should be considered for CRC screen using FIT. 2.Grade IV cases can be reduced with NTG and topical Lidocaine or a pudendal block. Banding done later after swelling reduced. Rx associated fissures and encourage sitz baths and supine position. Consider Flagyl Rx. 3.External disease can not be banded but will frequently shrink and be retracted by banding. 4.Associated symptomatic skin tags can be removed as a separate office procedure under local anesthesia. Less than 10% of cases.
Hemorrhoidectomy Indications 1.Failed Banding 2.Not capable of tolerating office procedure 3.Large external hemorrhoidal disease? 4.Grade III to IV hemorrhoidal disease? We have treated all grades of hemorrhoids and have not referred anyone to surgery to date.
Rectal Examination 1.Inspect for rash, skin tags, externals, fissure. 2.Use adequate lubrication and gentle palpation. If pain and spasm present consider NTG and lidocaine ointment. 3.Rigid Sigmoidoscopy to asses lower 15 cm. 4.Side viewing anoscope, rotate handle to banding area, remove obturator. 5.Insert ligator and apply suction 1-2 cm above dentate line. Rotate ligator, lock, and fire if no pain. 6.Check position with finger and roll up band if painful or too tight and muscle is caught in band. 7.Order of LL, RA, RP may be adjusted to avoid an external thrombosis, fissure, or to band a bleeding hemorrhoid.
CRH Banding via Slotted Anoscope
CRH Banding - by position
Rubber Band Ligation
Pre-banding Preparation 1.No laxatives, bowel preparation, enemas are needed. 2.Prophylactic antibiotics should be given in patients with valvular heart disease, stents, prosthesis, or those with decreased immunity. Amoxicillin or Biaxin plus Flagyl if neutropenic. 3.Stop aspirin and anticoagulants if possible for 5 days before and after banding. 4.Three hemorrhoids will require three bands in most patients. Appointments are two weeks apart.
After care 1.Patients may resume normal activities after the banding but should avoid strenuous activities till next day. 2.There may be a feeling of heaviness or fullness for 1-2 days. 3.Avoid constipation. Continue with fiber and fluids. 4.Bleeding may occur which may be from associated fissure or other hemorrhoids. Lie down on side, drink fluids, apply ice to anal area, and if persists call physician. Apply AgNO4, stop NTG for 2 days. 5.Call physician for urinary retention, fever, myalgia, flu like symptoms. Flagyl and Levaquin should be promptly started and hospitalization considered for suspected sepsis. 6.The band will fall off and pass in 1-7 days. 7.Fourth visit 3 weeks after last band for FIT.
Contraindications to Banding Anticoagulants such as Coumadin, Plavix, or aspirin are a relative contraindication to hemorrhoid treatment and if possible it is best to stop them for 5 days before and after banding. Dr. Cleator has banded patients on coumadin (30 times in 10 patients) and had only one moderate bleed which resolved with lying down. In portal hypertension the rectal varices are treated by treating the portal hypertension. Rx fissures with NTG. In pregnancy try to avoid rectal procedures to avoid the rare complication of pelvic sepsis or the liability of abortion. Anal fissures may be treated with NTG.
FIT-Immunochemical Fecal Blood Test At the end of the treatment a screening test for human blood in the stool is performed – the FIT, fecal immunochemical testing. Two-three stool samples are brushed. Tests for intact human hemoglobin from lower GI tract. Twice the yield of cancer and polyps compared to Hemocult II Sensa. Detects 80-94% of cancers and larger adenomas. No preparation required. InSure, HemeSelect. More expensive. Avoid test for hematuria, menstrual period, cuts on hands. About 2% of patients with typical symptoms of hemorrhoids turn out to have cancer or large polyps. Treating the hemorrhoids first decreases the rate of positive FIT and the need for colonoscopy to less than 10%.
FOBT Fecal occult blood test is noninvasive test for fecal blood to be done at home. Preferred-Sensitive guaiac Hemoccult II Sensa. Guaic based test-wood resin of Guajacum tree Hemoccult II, Hemoccult II Sensa - guaic smear test done on three samples and developed with hydrogen peroxidase. EZ Detect, ColoCARE-flushable reagent pads for home test uses chromogenic dye and not affected by meat or vitamin C. Patients prefer ease of use but not as sensitive (21 vs. 72%) Stop aspirin, NSAIDs, Vitamin C. No red meat, horseradish, cantaloupe/melon, grapefruit, figs, raw turnips, broccoli, cauliflower, red radishes, and parsnips for 3-5 days. Annual screening reduces death from colon cancer by 33%. 45% false positives. Hemorrhoids, diverticulosis, PUD, fissure.
FIT vs. FOBT HemeSelect, InSure, Flexsure use monoclonal or polyclonal antibodies to detect globin protein. Globin does not survive passage from upper GI tract. FIT true-positive. CRC 87.5% vs. 54.2%. Significant adenomas (high grade dysplasia, villous change, >10mm) 42-47% vs. 23 %. Reduces false positives and the need for colonoscopy No need to modify diet or avoid aspirin. Cost $5 for Hemoccult II Sensa vs $75 for FIT
ACS Advisory Group Recommendations FIT Immunochemical tests have advantages over guaiac tests….these tests offer enhanced specificity in colorectal cancer screening compared with guaiac- based testing. “in comparison with guaiac-based tests for the detection of occult blood, immunochemical tests are more patient-friendly, and are likely to be equal or better in sensitivity and specificity.”
Rectal Bleeding and Colonoscopy 1.Incidence of Colon Cancer in patients with chronic intermittent rectal bleeding that is typical of hemorrhoids with no abdominal pain, change in bowel habits and rectal cancer not present on anoscopy is %. In those under the age of 50 it is 0-3%. Other causes include polyps, fissures, diverticulosis, IBD. 2.The average approved reimbursement for colonoscopy is approximately $2200 compared to $1200 for banding. 3.Complications occur in 1-5% including perforation at a rate of.05-.3% and bleeding at a rate of.1-2%. 4.Colonoscopy misses 2-6% of colon cancers Bright red rectal bleeding with bowel movements is a common complaint. Benign lesions are the most common cause.
Do All Patients with Rectal Bleeding Typical of Hemorrhoids Need Colonoscopy Yes. Symptoms are unreliable and significant pathology is found in 20-40%; CRC, polyps, IBD, fissure, diverticulosis, angiodysplasia, rectal ulcers or proctitis, infectious or ischemic colitis. No. Having an effective office hemorrhoid treatment changes the approach. Banding the hemorrhoids first and restricting colonoscopy to those with positive FIT post banding is safe, cost effective, provides effective treatment, and avoids colonoscopy in over 90% of patients.
Indications for Colonoscopy in Evaluation of Hemorrhoids 1.History or physical findings suggestive of cancer or IBD. Abdominal pain, weight loss, change in bowel habits, no obvious source of bleeding. 2.Iron deficiency anemia 3.Positive FIT/after RX 4.Age over 40 with 1 st degree relative with CRC or adenoma<60 and no BE or colonoscopy within 10 years. 5.Age over 40 with two 1 st degree relatives and no evaluation within 3-5 years.
American Cancer Society Colorectal Cancer Screening Guidelines Beginning at age 50 (45 for African Americans), men and women who are at average risk for developing colorectal cancer should have 1 of the 5 screening options below: a fecal occult blood test (FOBT)* or fecal immunochemical test (iFOBT or FIT)* every year**, OR flexible sigmoidoscopy every 5 years, OR an FOBT* or FIT* every year plus flexible sigmoidoscopy every 5 years**, OR (Of these first 3 options, the combination of FOBT or FIT every year plus flexible sigmoidoscopy every 5 years is preferable.) double-contrast barium enema every 5 years**, OR colonoscopy every 10 years *For FOBT or FIT, the take-home multiple sample method should be used. **Colonoscopy should be done if the FOBT or FIT shows blood in the stool, if sigmoidoscopy results show a polyp, or if double-contrast barium enema studies show anything abnormal. If possible, polyps should be removed during the colonoscopy.
2007 ACS Current Guidelines iFOBT was added in Postpolypectomy and Postcolorectal cancer resection surveillance revised. Follow-up intervals were often shorter than recommended, raising cost and complications. Single FOBT in the office is not recommended because of low sensitivity.
Risk Category Age to BeginRecommendation Comments Increased Risk Single <1cm adenoma 5-10 years later Colonoscopy If normal resume average risk Multiple adenomas, Within 3 years Colonoscopy If normal repeat in 5 years, if >1cm, villous, normal resume average risk High grade dysplasia S/P Curative Resection 3-6 months then Colonoscopy If normal repeat in 3 years, if 1 year normal then repeat every 5 years or more often for HNPCC Colorectal cancer or Age 40 or 10 yrs Colonoscopy Every 5-10 years Adenomatous polyps, in before youngest 1 st degree relative <60, case or 2 or more 1 st degree relatives at any age (not a hereditary syndrome) ACS Guidelines on Screening and Surveillance for the Early Detection of Colorectal Adenomas and Cancer

Screening for CRC Ideal screening should be safe, easy, reliable, inexpensive. Current compliance for CRC screening is 35% 4-7% of people develop CRC during lifetime. Screening colonoscopy will result in no benefit to over 90% of us but subject us to the expense and morbidity of the exam. Sufficient colonoscopic and economic resources not available in most areas. Colonoscopy misses 5% of cancers and 20% of polyps. FIT is a reasonable recommendation in the average risk group.
CT Colonography 1. Helical CT scan creates two and three-dimensional images. Prepare with phospha-soda and bisacodyl. Air insufflation. 2. Accurate in detection of polyps greater than 10 mm and colon cancer. 3. False positives 15% unnecessary colonoscopy from retained stool, diverticular disease, thick or complex haustral folds, metal or motion artifacts. 4. May miss flat adenomas which are more aggressive. 5. Non therapeutic. 6. More expensive and not covered by insurance.
DNA Stool Testing Screening Stool for DNA Mutations Still under investigation. Only one sample required. Non-invasive, no preparation. Requires entire bowel movement be sent to lab. May be more specific for cancer and polyps Expensive at over $400 per test. K-ras, APC, p53, Bat-26, and long DNA tested.
Research Opportunity 4-7% of people develop CRC during their lifetime. A prospective study on the diagnosis and treatment of rectal bleeding typical of hemorrhoids. The role of hemorrhoidal banding, FIT, and colonoscopy. A cooperative project of primary care providers, GI specialists, and the Center for Colorectal Health. Patients with rectal bleeding typical of hemorrhoids will be evaluated, banded, undergo FIT, and then colonoscopy. When is colonoscopy indicated? Age, sex, length or type of symptoms.
Thrombosed External Hemorrhoid
Thrombosed External Hemorrhoids 1.Typical presentation is acute rectal pain and mass. 2.Associated with heavy lifting, straining, sitting, diarrhea. 3.Rx warm baths, stool softeners, Lidocaine ointment, analgesics, supine position, Nifedipine, NTG, or diltiazem ointment. 4.Surgical excision best done within first 72 hrs. for severe pain, ulceration, rupture. Open vs. closed excision. 5.When associated with 3-4 th degree hemorrhoids will require pudendal block and reduction of prolapse. Avoid surgery if possible. 6.Up to 50% will experience further hemorrhoid problems. After acute episode resolves proceed with anoscopy and banding. 7.Look for associated fissure.
Anal Fissure Acute posterior anal fissure producing pain on digital exam. Sphincter tone increased. Exam limited by pain that may respond to NTG and Lidocaine.
Anal Fissures 1.A linear tear in the skin of the anal canal caused by passage of a hard stool, diarrhea, straining, sitting too long. May be seen in IBD or after rectal surgery. Increased sphincter tone. 2.Deep fissures expose underlying internal sphincter, white color. 3.Spasm, irritation, itching, pain after BM, and bleeding. 4.Acute fissures may heal with sitz baths, fiber, brief Rx steroid cream, leading to thin skin and sentinel pile. Pile may shrink after Rx. If persists may be excised after Rx of fissure completed. 5.Associated hemorrhoids are common. 6.NTG, Lidocaine ointment, fiber, fluids, no straining, banding. 7.Infected fissures Rx Flagyl.
Anal Fissure Rx 6 weeks of twice a day intra-rectal NTG ointment,.12%, then 6 weeks of once a day NTG. Watch for headaches, tachycardia, or light headiness. Do not use NTG in patients on Viagra or Cialis. Recurrences require repeat NTG Rx and increasing fiber. 5% Lidocaine ointment as needed. 2 % Diltiazem, calcium channel blocker. ointment is an alternative in those with headaches and is used three time per day and may take longer. Botox effectively paralyzes internal sphincter but costs $600 per vial and may cause incontinence. May be used in combination with NTG. Surgery is effective but has a 10% incontinence rate. Pudendal block may be rarely required for pain relief.
NTG Nitroglycerin relaxes smooth muscle, decreases resting pressure, and improves blood supply. Side effects: hypotension, bradycardia, tachycardia, headache, rash, dizziness, dyspepsia, flushing, blurred vision, dry mouth, fainting. Avoid with congestive heart failure, calcium channel blockers, beta blockers, Viagra, Cialis. Has been used in pregnancy without difficulty so far but has not been adequately tested.
Diltiazem Calcium-channel blocker relaxes smooth muscle and increases blood supply. Side effects: dizziness, lightheadedness, flushing, headache, tiredness, bradycardia, dyspepsia, nausea, vomiting, diarrhea, constipation, abdominal pain, dry mouth, edema, nervousness, insomnia. Allergic reactions may occur. 2% ointment of Cardizem, Dilacor, Tiazac. Avoid in heart block, beta-blockers, heart failure. May increase Digoxin or Tegretol levels. Tagamet increases blood levels.
CRH Rx of Fissures The combined therapy at CRH of using fiber, bathroom behavior modification, NTG, and banding of internal hemorrhoids heals a high percentage of anal fissures while avoiding the expense, pain, disability, and risk of internal sphincterotomy and hemorrhoidectomy.
Skin tags Skin tags are extra folds of skin around the anal verge. Caused by stretching of skin from dilated external hemorrhoids. May interfere with cleaning and add to pruritus ani. Cosmetic issue to some. Skin tag and can be removed or left alone depending on preference. Removal requires local anesthesia and office excision. Takes 15 minutes and leads to 2-3 days of discomfort.
Associated skin tags
Pruritus Ani 1.Chronic itching and rash around the anus. 2.Caused by leakage of stool and mucous leading to inflammation of skin, dermatitis. 3.Hemorrhoids, fissures, and poor hygiene may lead to itch. 4.Fungal infections may occur, more common in DM. 5.Contact dermatitis may occur from soap, perfumes, dye in toilet paper, or hemorrhoid creams or wipes. 6.Citrus fruits, grapes, tomatoes, spices, beer, milk, tea, or coffee may exacerbate condition. 7.Laxatives, colpermin, and antibiotics may cause itch. 8.Keep area clean and dry at all times. Loose pants and cotton underwear. Balneol and Lotrimin or Lotrisone Rx. Band hemorrhoids and treat fissure.
