Start with what you need treated.

Tonsillectomy removes the tonsils, lymphoid tissue at the back of the throat that can become chronically infected or enlarged enough to obstruct breathing, particularly during sleep in children. The surgeon removes the tonsils entirely through the mouth using traditional dissection or newer techniques like coblation, without any external incision. The procedure is performed under general anesthesia and typically takes 20 to 30 minutes. Patients, especially children, commonly experience throat pain, difficulty swallowing, and sometimes ear pain for one to two weeks following surgery, managed with pain medication and a soft, cool diet. There is a small risk of bleeding during the healing period, which is why activity restrictions are advised initially. Most patients experience a marked reduction in throat infections and improved sleep quality after full recovery.

Tympanoplasty repairs a hole or damage in the eardrum, often caused by chronic infection, trauma, or prior ear surgery, which can lead to hearing loss and recurrent middle ear infections if left untreated. The surgeon uses a small graft, typically taken from tissue near the ear such as fascia or cartilage, to patch the perforation, accessing the eardrum either through the ear canal or via a small incision behind the ear depending on the size and location of the defect. The procedure is performed under local anesthesia with sedation or general anesthesia and typically takes one to two hours. Patients are advised to keep the ear dry and avoid activities that increase middle ear pressure, such as flying or diving, for several weeks. Follow-up visits monitor graft healing and hearing improvement over the following weeks to months. Most patients experience significant improvement in hearing and a marked reduction in ear infections.

Tympanostomy tube insertion, often called ear tube surgery, treats recurrent middle ear infections or persistent fluid buildup behind the eardrum that causes hearing loss, most commonly performed in young children. The surgeon makes a tiny incision in the eardrum and inserts a small tube that allows air to enter the middle ear and fluid to drain out, preventing pressure buildup and reducing infection recurrence. The procedure is very quick, typically taking only 10 to 15 minutes, performed under brief general anesthesia in children or local anesthesia in cooperative older patients. Children usually return to normal activity the same day, with hearing often improving immediately once fluid drains from the middle ear. The tubes typically remain in place for six months to a year before naturally falling out as the eardrum heals. Most children experience a significant reduction in ear infections and improved hearing while the tubes are in place.

Anti-reflux procedures are used to treat gastroesophageal reflux disease (GERD) that does not respond adequately to medication, or when patients prefer to avoid long-term drug therapy. The most common surgical option, laparoscopic Nissen fundoplication, involves wrapping the upper part of the stomach around the lower esophagus to reinforce the natural valve and prevent acid from flowing backward. The procedure is performed under general anesthesia through small keyhole incisions, typically taking one to two hours. Patients follow a liquid to soft diet for the first couple of weeks to allow healing while minimizing strain on the new wrap. Most patients experience substantial and lasting relief from heartburn and regurgitation symptoms. Long-term follow-up ensures the repair remains effective over time.

Bowel obstruction treatment depends on the cause, severity, and whether the blockage is partial or complete, with conditions ranging from adhesions after previous surgery to hernias, tumors, or inflammatory bowel disease. Many partial obstructions are initially managed conservatively with bowel rest, intravenous fluids, and a nasogastric tube to decompress the stomach and intestines, allowing the bowel to recover on its own. Complete obstructions, or those not improving with conservative care, typically require surgery to remove the blockage, repair a hernia, or resect a segment of damaged bowel. Surgical treatment is performed under general anesthesia and can be done laparoscopically or through open surgery depending on the situation's urgency and complexity. Patients gradually reintroduce oral intake as bowel function returns, monitored closely for signs of recurrence. Prompt treatment prevents serious complications such as bowel perforation or tissue death.

Cyclic vomiting syndrome treatment combines preventive strategies with supportive care during acute episodes, since the exact cause of this condition, which involves recurrent bouts of intense nausea and vomiting, is not always identified but is often linked to migraine physiology, stress, or specific triggers. Preventive medications, such as certain antidepressants or anti-migraine drugs, are used between episodes to reduce their frequency and severity, alongside identifying and avoiding personal triggers like specific foods, stress, or sleep deprivation. During an acute episode, treatment focuses on intravenous fluids to prevent dehydration, anti-nausea medication, and pain relief, sometimes requiring a brief hospital stay for more severe episodes. Patients often keep a symptom diary to help identify patterns and triggers unique to their condition. With appropriate preventive treatment, many patients experience a significant reduction in the frequency and intensity of episodes over time. Long-term management by a gastroenterologist helps optimize the treatment plan.

The duodenal switch is one of the most effective bariatric procedures for severe obesity, combining a sleeve gastrectomy, which reduces stomach size, with a significant rerouting of the small intestine that limits calorie and nutrient absorption. This dual restrictive and malabsorptive approach leads to substantial and durable weight loss, along with notable improvement or resolution of type 2 diabetes and other obesity-related conditions. The surgery is performed laparoscopically under general anesthesia and typically takes two to four hours due to its complexity. Because of the malabsorptive component, patients require lifelong vitamin and mineral supplementation and regular blood monitoring to prevent nutritional deficiencies. Dietary changes and follow-up with a bariatric team are essential for long-term success. This procedure is generally reserved for patients with the highest degree of obesity or those who have not achieved sufficient results with other bariatric procedures.

GERD treatment follows a stepwise approach, beginning with lifestyle modifications such as weight loss, dietary changes, and avoiding late meals, combined with acid-suppressing medications like proton pump inhibitors to reduce stomach acid production and allow the esophagus to heal. For patients with severe symptoms, esophageal damage, or those who wish to avoid long-term medication, surgical options such as laparoscopic fundoplication can be considered to reinforce the valve between the esophagus and stomach. Diagnostic tests such as endoscopy or pH monitoring may be used to confirm the diagnosis and assess severity before deciding on treatment approach. Medical management is typically managed on an outpatient basis with regular follow-up to adjust medication as needed. Surgical treatment, when required, involves a short hospital stay with a gradual return to normal diet. Most patients achieve good symptom control with appropriate combined lifestyle and medical or surgical treatment.

Gastrointestinal stromal tumor (GIST) treatment is primarily surgical, involving complete removal of the tumor with clear margins, since these tumors generally do not spread to lymph nodes, making extensive lymph node dissection unnecessary in most cases. Surgery can often be performed laparoscopically for smaller, well-localized tumors, while larger tumors may require open surgery, both performed under general anesthesia. For patients with higher-risk features such as larger tumor size or high mitotic rate, or for tumors that cannot be completely removed surgically, targeted drug therapy with tyrosine kinase inhibitors like imatinib is used before or after surgery to shrink the tumor or eliminate residual disease. Recovery from surgery typically follows standard abdominal surgery timelines, with a gradual return to normal diet and activity. Regular follow-up imaging monitors for recurrence, as GISTs can occasionally return even after apparently complete removal. Most patients with localized GIST have excellent long-term outcomes with appropriate surgical and, when needed, targeted drug treatment.

IBS treatment is individualized based on whether the predominant symptom is diarrhea, constipation, or a mix of both, and typically combines dietary changes, such as a low-FODMAP diet, with medications targeting specific symptoms like antispasmodics for pain, laxatives for constipation, or anti-diarrheal agents as needed. Identifying and managing stress, since it commonly triggers or worsens symptoms, is an important part of a comprehensive treatment plan, sometimes including techniques like cognitive behavioral therapy or gut-directed hypnotherapy. Treatment is managed entirely on an outpatient basis with regular follow-up to adjust the approach based on symptom response. A trial-and-error process is often needed to find the most effective combination of dietary and medical strategies for each individual. Most patients achieve meaningful symptom improvement and better quality of life with a personalized, multi-faceted treatment approach. Long-term management focuses on sustaining symptom control and adapting the plan as triggers or symptoms change over time.

Peptic ulcer treatment addresses the underlying cause, most commonly infection with Helicobacter pylori bacteria or long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs), combined with acid-suppressing medications such as proton pump inhibitors to allow the ulcer to heal. When H. pylori infection is identified through testing, a combination of antibiotics along with acid suppression, known as triple or quadruple therapy, is prescribed for one to two weeks to eradicate the bacteria. Most uncomplicated ulcers are managed entirely on an outpatient basis, with follow-up testing to confirm healing and eradication of infection where relevant. Complications such as bleeding, perforation, or obstruction require urgent hospital admission and may need endoscopic treatment or emergency surgery to address the complication directly. Avoiding NSAIDs, alcohol, and smoking supports healing and reduces the risk of recurrence. With appropriate treatment, the vast majority of peptic ulcers heal completely and do not recur.

Hemorrhoid surgery is recommended for severe or persistent hemorrhoids that do not respond adequately to conservative measures like dietary fiber, topical treatments, or minimally invasive office procedures such as banding. The surgeon removes the enlarged hemorrhoidal tissue through a hemorrhoidectomy, or uses a stapling technique that repositions hemorrhoidal tissue and interrupts its blood supply, chosen based on the severity and pattern of the hemorrhoids. The procedure is typically performed under general, spinal, or local anesthesia with sedation, taking 30 minutes to an hour. Post-operative pain is common for the first one to two weeks, managed with pain medication, sitz baths, and stool softeners to ease bowel movements during healing. Most patients return to normal activity within one to two weeks, with complete healing over several weeks. Surgery offers the most definitive and long-lasting relief for severe hemorrhoid disease.
