Sleeve gastrectomy is a bariatric operation in which a substantial portion of the stomach is removed to create a smaller, tube-shaped stomach. The procedure can help reduce food intake and influence appetite-related hormones. It may be considered for appropriately selected patients with obesity after comprehensive medical assessment.
Roux-en-Y gastric bypass creates a small stomach pouch and redirects part of the small intestine. It supports weight loss through changes in food intake, digestion and hormonal signalling. The procedure may also improve certain obesity-related metabolic conditions, although it requires lifelong nutritional monitoring and follow-up.
One-anastomosis gastric bypass is a metabolic and weight-loss operation that creates a long gastric pouch connected to the small intestine. It changes nutrient passage and can support substantial weight reduction in selected patients. The procedure requires careful assessment of reflux risks, nutritional requirements and long-term follow-up.
Single-Anastomosis Duodeno-Ileal Bypass with Sleeve Gastrectomy combines sleeve gastrectomy with intestinal bypass. It is a specialised metabolic operation considered in selected patients with severe obesity or complex metabolic needs. Long-term monitoring is important because nutritional deficiencies and other complications can develop.
Revisional bariatric surgery may be considered when a previous weight-loss operation results in complications, inadequate weight reduction or significant weight regain. The procedure depends on the original surgery and current anatomy. Detailed evaluation is essential because revision operations can be more complex than initial bariatric procedures.
Gastric band removal involves removing an adjustable band previously placed around the stomach. It may be recommended because of complications such as slippage, erosion, intolerance or inadequate weight management. Some patients may require additional bariatric treatment after removal, depending on their clinical needs.
Metabolic surgery may improve blood glucose control in appropriately selected people with obesity and type 2 diabetes. Procedures alter gastrointestinal anatomy and hormonal responses. Treatment requires comprehensive assessment and continued diabetes monitoring because surgery does not guarantee permanent remission in every patient.
Fundoplication is an anti-reflux operation that reinforces the barrier between the stomach and oesophagus. It may be considered for selected patients with gastroesophageal reflux disease when medical treatment is insufficient or an anatomical problem is present. Preoperative investigations help determine whether surgery is appropriate.
A hiatal hernia occurs when part of the stomach moves upward through the diaphragm. Some patients experience reflux, regurgitation or swallowing symptoms. Surgical repair may be considered for selected symptomatic or complicated cases and can involve repositioning the stomach and repairing the diaphragmatic opening.
Laparoscopic hernia repair uses small incisions, a camera and specialised instruments to repair selected abdominal wall or groin hernias. Surgical mesh may be used when appropriate. Suitability depends on the hernia type, previous procedures, patient health and the surgeon's assessment.
Laparoscopic cholecystectomy removes the gallbladder using small abdominal incisions. It is commonly performed for symptomatic gallstones and selected gallbladder conditions. Surgical evaluation considers the severity of symptoms, imaging findings and potential complications before recommending treatment.
Robotic surgery uses computer-assisted instruments controlled by the surgeon to perform selected procedures through small incisions. It may provide additional instrument movement and visualisation in complex operations. The choice between robotic, laparoscopic and open surgery depends on the condition and clinical circumstances.
