Rectal Pain & Bleeding
The rectum, the last segment of the digestive tract, plays a crucial role in maintaining our digestive health. Despite the prevalence of rectal problems, a significant number of adults hesitate to seek medical advice due to embarrassment. This article aims to provide a thorough understanding of common rectal issues, emphasizing the importance of early recognition and proper diagnosis.
Hemorrhoids, akin to varicose veins in the legs, can become swollen or stretched. They manifest in two types: external, visible under the skin, and internal, originating inside the rectum. The development of hemorrhoids is often linked to increased pressure during bowel movements, pregnancy, constipation, diarrhea, genetic factors, and aging. Diagnosis involves visual examination, rectal examination, and sometimes anoscopy or sigmoidoscopy. Medical treatment focuses on softening bowel movements, topical creams, sitz baths, and dietary adjustments.
Various procedures exist for treating hemorrhoids. These include banding (placing a rubber band to induce strangulation and scarring), sclerotherapy (injection of a chemical solution to shrink hemorrhoids), infrared coagulation (using a device to destroy internal hemorrhoids), radiofrequency ablation (employing high-intensity sound waves to close off hemorrhoids), and hemorrhoidectomy (surgical removal of hemorrhoid veins, typically requiring hospitalization).
An anal fissure is a common condition involving a tear in the lining of the anal canal. Diagnosis is achieved through a painful digital examination, external inspection, or anoscopy. Treatment involves prevention through a high-fiber diet, sitz baths, stool softeners, and topical creams. Surgical intervention may be necessary if symptoms persist.
Anal abscesses, pus-filled cavities, and fistulas, connections or tunnels between the anal gland and buttocks, present with symptoms such as pain, swelling, and fever for abscesses and drainage for fistulas. Medical options exist for abscesses caused by underlying conditions like Crohn’s disease, while surgical options involve cutting the sphincter muscle.
Fecal incontinence, characterized by the accidental loss of stool, has various causes. Evaluation methods include anorectal examination, digital examination, anal manometry, X-rays, and ultrasound. Treatment options range from dietary modification and medicines to biofeedback and surgery, depending on the underlying cause.
Pruritus ani, itching around the anal area often aggravated by excessive cleaning, can have causes such as excessive cleaning, sweating, certain beverages, and rarely infections or skin conditions. Treatment involves avoiding irritating soaps, blotting the area gently, eliminating irritating foods, and considering protective pastes.
SMALL BOWEL CAPSULE ENTEROSCOPY
A novel diagnostic tool that allows direct visualization of the small intestine. A vitamin-sized capsule containing a miniature camera is swallowed by the patient and takes thousands of pictures as it travels through the gastrointestinal tract.
Small bowel capsule enteroscopy was approved by the FDA in 2001 as a tool to examine the small intestine, which previously could not be visualized well with traditional endoscopy. The capsule camera takes approximately 50,000 images during its travels through the GI tract, providing significantly more visualization than other methods. Capsule endoscopy is a non-invasive way to diagnose small bowel abnormalities and diseases, such as Crohn’s disease, ulcers, celiac disease, small bowel tumors, and sources of GI bleeding.
Patients fast overnight before capsule endoscopy. The next morning, they ingest the vitamin-sized capsule with water. Images are transmitted to a data recorder worn in a belt around their waist. Patients go about normal daily activities as the capsule camera takes images, while the sensors track its location and collect the images. After 8-12 hours, the images are downloaded to a computer workstation for physician review. Patients pass the capsule naturally in their stool within 1-2 days.
A physician carefully reviews the thousands of capsule images looking for abnormalities. Diagnostic findings include ulcers, bleeding, tumors, blockages, polyps, villous atrophy from celiac disease, and signs of Crohn’s disease. The images provide direct visualization to confirm diagnoses. However, capsule location can only be estimated based on image transit times. If an abnormality is seen, its exact location may be unclear. Another endoscopic procedure may be required to take biopsies or provide therapy.
A major limitation of capsule endoscopy is the lack of therapeutic capabilities. It is strictly a diagnostic tool. Additionally, there is a small risk of capsule retention if a stricture is encountered. Capsule retention requires surgical or endoscopic removal. Some patients may have difficulty swallowing the capsule. Improper sensor placement or interference can also cause poor image quality. However, capsule endoscopy is considered very safe with few complications.
Upper Endoscopy/ EGD
An EGD utilizes an endoscope, a flexible tube equipped with a camera and light, to meticulously examine the upper digestive tract. This includes the esophagus, stomach, and the upper part of the small intestine known as the duodenum. Through this procedure, physicians obtain visual insights into the digestive tract, capturing detailed images and, if necessary, conducting biopsies of abnormal tissue.
The necessity for an EGD arises in cases where patients exhibit symptoms indicative of upper digestive tract disorders. These may include bleeding, heartburn, nausea, vomiting, abdominal pain, trouble swallowing, unexplained weight loss, and more. Conditions diagnosed through EGD encompass bacterial infections, celiac disease, Crohn’s disease, GERD, esophagitis, gastritis, duodenitis, narrowing or blockage of the esophagus, and both benign and malignant tumors.
Beyond diagnosis, EGD is a versatile tool for treating various conditions. Physicians may employ it to assess complications, control bleeding, monitor treatment effectiveness, open narrowed areas, and remove growths, tumors, or foreign objects. The adaptability of EGD makes it a valuable asset in managing a spectrum of upper digestive tract disorders.
While an EGD is not inherently painful, it can cause discomfort. To mitigate this, patients typically receive sedatives administered through an intravenous line. The choice of sedative and its administration method is tailored to individual needs, ensuring a comfortable and pain-free experience. Adequate preparation, including fasting and medication adjustments, is crucial for the success of the procedure.
The day of the procedure involves meticulous preparation, including changes into a hospital gown, vital sign measurements, IV placement, and a review of medical history. During the EGD, patients may undergo numbing of the throat, receive sedation, and assume a left-side position as the endoscope navigates the digestive tract. Post-procedure, patients are monitored in a recovery area, receiving instructions on diet, activities, and medications. Some cases may require overnight hospital stays, while others permit return home with a designated driver.
While EGD is generally safe, like any medical procedure, it carries some rare risks, including tears, bleeding, and infection. Potential reactions to sedatives are also considered. Alternatives to EGD include diagnostic imaging tests such as CT scans or upper GI series, offering non-invasive options with distinct considerations.
