General Surgery — Find Specialists & Top Hospitals Worldwide | MyMedicPlus

General surgery is a broad surgical specialty encompassing the diagnosis and surgical management of diseases affecting the abdomen, gastrointestinal tract, liver, pancreas, gallbladder, breast, thyroid and parathyroid glands, skin, soft tissues, and abdominal wall. It is the foundational surgical discipline from which virtually all other surgical subspecialties have evolved, and it remains the specialty of choice for a wide range of the most common and urgent surgical conditions encountered in clinical practice.

The term 'general surgery' is somewhat misleading today, as most practising general surgeons develop substantial subspecialty expertise in one or more areas: colorectal surgery (colon cancer, diverticular disease, inflammatory bowel disease); hepatobiliary and pancreatic surgery (liver, bile duct, and pancreatic disease); breast surgery (breast cancer, benign breast disease); minimally invasive and laparoscopic surgery; surgical oncology; and endocrine surgery (thyroid, parathyroid, adrenal). The generalist foundation allows these surgeons to also manage emergency and trauma cases across all of these organ systems, which remains a hallmark of the specialty.

The revolution in minimally invasive surgery has fundamentally transformed general surgery over the past three decades. Laparoscopic (keyhole) cholecystectomy — introduced in the late 1980s — became the standard of care within years of its introduction and represented a paradigm shift in surgical practice. Today, the vast majority of common general surgical procedures — cholecystectomy, appendectomy, hernia repair, colectomy, and many thyroid and foregut operations — can be performed laparoscopically or robotically, with dramatically reduced pain, shorter hospital stays, and faster recovery compared to traditional open surgery.

General surgeons diagnose and treat a wide range of conditions across the abdominal, gastrointestinal, breast, and endocrine systems:

• Appendicitis: Acute inflammation of the appendix causing right lower quadrant abdominal pain, nausea, fever, and localised tenderness; treated with laparoscopic appendectomy. A surgical emergency if perforation occurs.
• Gallbladder disease (cholelithiasis and cholecystitis): Gallstones and gallbladder inflammation causing right upper quadrant pain, nausea, and biliary colic; treated with laparoscopic cholecystectomy, the most commonly performed general surgical operation worldwide.
• Inguinal, umbilical, and incisional hernias: Protrusions of abdominal contents through weakness in the abdominal wall; symptomatic or enlarging hernias are repaired laparoscopically or with open mesh-based techniques to prevent strangulation.
• Hiatal hernia: Protrusion of the stomach through the oesophageal hiatus of the diaphragm causing GERD; large or symptomatic hiatal hernias require surgical repair with fundoplication.
• Colorectal cancer: Malignancy of the colon or rectum requiring surgical resection (colectomy or anterior resection) with curative or palliative intent, often combined with chemotherapy and radiotherapy.
• Diverticular disease: Diverticulitis (inflamed colonic diverticula) causing left lower quadrant pain, fever, and peritonitis; complicated cases or recurrent diverticulitis may require sigmoid colectomy.
• Bowel obstruction: Mechanical obstruction of the small or large intestine from adhesions, hernia, volvulus, or tumour; urgent surgical decompression or bowel resection may be required.
• Breast cancer and benign breast disease: Breast conservation surgery (lumpectomy), mastectomy, sentinel lymph node biopsy, and axillary clearance for breast malignancy; excision of fibroadenomas, breast cysts, and other benign lesions.
• Thyroid and parathyroid disease: Thyroidectomy for thyroid cancer, large goitre, or Graves disease; parathyroidectomy for primary hyperparathyroidism causing hypercalcaemia.
• Soft tissue and skin tumours: Excision of lipomas, sebaceous cysts, skin cancers, and sarcomas; sentinel lymph node biopsy and lymph node dissection for melanoma.
• Haemorrhoidal disease and anorectal conditions: Haemorrhoidectomy, lateral internal sphincterotomy for anal fissure, drainage of perianal abscess, and fistula surgery.

General surgeons perform a wide spectrum of elective and emergency operations:

• Laparoscopic cholecystectomy: Removal of the gallbladder through three or four small port incisions using a laparoscope and instruments; the gold standard treatment for symptomatic gallstones and cholecystitis. Typically requires 1 night in hospital and 1–2 weeks recovery.
• Laparoscopic appendectomy: Removal of an inflamed appendix through laparoscopic access; favoured over open appendectomy for lower infection rates and faster recovery. Urgent emergency procedure for acute appendicitis.
• Hernia repair (laparoscopic TEP/TAPP and open mesh): Defects in the abdominal wall are reinforced with prosthetic mesh; laparoscopic totally extraperitoneal (TEP) or transabdominal preperitoneal (TAPP) repair and open Lichtenstein mesh repair are established techniques for inguinal hernia.
• Colectomy and bowel resection: Removal of a diseased segment of colon or small bowel for cancer, diverticulitis, IBD, or ischaemia; performed laparoscopically or robotically when possible. May result in temporary or permanent stoma.
• Mastectomy and breast conservation surgery: Removal of the breast (total mastectomy) or tumour with clear margins (wide local excision/lumpectomy) for breast cancer; sentinel lymph node biopsy performed to assess axillary nodal status.
• Thyroidectomy: Partial or total removal of the thyroid gland for thyroid cancer, multi-nodular goitre, or Graves disease; performed through a cervical incision with meticulous care to preserve the recurrent laryngeal nerves and parathyroid glands.
• Haemorrhoidectomy: Surgical excision or ligation of prolapsed internal haemorrhoids that have failed conservative and rubber band ligation treatment.
• Emergency laparotomy: Open abdominal exploration for peritonitis, bowel perforation, major abdominal trauma, or other acute surgical emergencies; a high-risk procedure performed in extremis when less invasive options are not feasible.
• Nissen fundoplication: Anti-reflux operation wrapping the stomach fundus around the lower oesophagus to prevent acid reflux; performed laparoscopically for GERD refractory to medical therapy or hiatal hernia.

Referral to a general surgeon is appropriate when a condition has been identified that requires surgical evaluation or operative treatment. Many referrals come from primary care physicians, gastroenterologists, or emergency departments.

Emergency surgical referral is required immediately for: suspected appendicitis (right lower quadrant pain, fever, nausea, and localised guarding) — do not delay, as perforation increases morbidity significantly; abdominal rigidity suggesting bowel perforation or peritonitis; a tender, non-reducible hernia suggesting strangulation (a surgical emergency that may progress to bowel ischaemia within hours); and significant rectal bleeding or haematemesis requiring urgent endoscopic and possible surgical haemostasis.

Urgent outpatient referral within days to weeks is appropriate for: symptomatic gallstones causing recurrent biliary colic or prior cholecystitis (to prevent recurrence and possible complications such as pancreatitis or choledocholithiasis); a new breast lump in any adult, particularly if it is hard, fixed, or associated with skin or nipple changes; a skin lesion suspicious for melanoma or non-melanoma skin cancer; a suspected hernia causing discomfort, particularly if it is enlarging or was recently reducible and no longer is; and change in bowel habit with rectal bleeding or unexplained weight loss requiring combined gastroenterology and surgical evaluation.

Routine referral is appropriate for: elective hernia repair in patients with chronic symptoms but no signs of strangulation; evaluation for anti-reflux surgery after failure of maximal medical therapy for GERD; thyroid surgery referral from an endocrinologist for thyroid cancer or large symptomatic goitre; and haemorrhoidal disease not responding to conservative treatment or office-based procedures.

General surgery training in the USA begins with a 4-year medical degree (MD or DO) followed by a comprehensive 5-year general surgery residency — one of the longest residency programmes in medicine. During the residency, trainees rotate through all aspects of general surgery including abdominal, colorectal, hepatobiliary, breast, endocrine, trauma, critical care, vascular, and paediatric surgery, gaining increasing operative responsibility throughout.

American Board of Surgery (ABS) certification requires successful completion of the residency programme, a written qualifying examination (QE) typically taken in the final year of residency, and an oral certifying examination (CE) administered 1–2 years after residency. The CE uses standardised patient scenarios to assess the candidate's ability to make appropriate surgical decisions, handle complications, and demonstrate ethical and professional behaviour under examination conditions.

Following ABS certification, many general surgeons pursue 1–2 year subspecialty fellowships in minimally invasive surgery, colorectal surgery, surgical oncology, hepatopancreatobiliary (HPB) surgery, breast surgery, endocrine surgery, trauma and acute care surgery, or bariatric and metabolic surgery. These fellowships provide additional training, volume, and credentialling for complex subspecialty procedures. Subspecialty fellowship training is accredited by the Fellowship Council or relevant surgical societies (SSO for oncology, ASCRS for colorectal, ASMBS for bariatric).

In the UK, general surgical training leads to CCT in General Surgery after 7 years of specialty training (ST3–ST8) following core surgical training, with subspecialty interest certificates available through the Association of Upper Gastrointestinal Surgeons (AUGIS), the Association of Coloproctology of Great Britain and Ireland (ACPGBI), and the British Association of Endocrine and Thyroid Surgeons (BAETS).

Most referrals to general surgeons come from primary care physicians, gastroenterologists, or emergency departments, though self-referral is possible in many healthcare systems. Verify ABS board certification through the American Board of Surgery website. When selecting a surgeon for an elective procedure, ask specifically about their annual volume of the operation you require — surgical outcomes, particularly for complex procedures such as colectomy, oesophagectomy, or pancreatectomy, improve significantly with higher surgical volume and specialist subspecialty experience.

For cancer operations (colorectal, pancreatic, hepatic, gastric), seek surgeons affiliated with National Cancer Institute (NCI)-designated cancer centres or equivalent specialist oncological units, where multidisciplinary tumour boards review cases and combined surgical-oncological expertise is available. For emergency surgery — appendicitis, perforated peptic ulcer, bowel obstruction — the nearest hospital with general surgical services is appropriate.

For your elective pre-operative consultation, bring all relevant imaging (CT scans, ultrasounds, endoscopy reports), blood tests, specialist referral letters, and a complete list of medications. Discuss the choice between laparoscopic and open surgery, expected hospital stay, recovery timeline at home, specific complication risks for your procedure and individual health status, and what to expect at your post-operative follow-up. Most elective laparoscopic procedures are performed as day cases or require just 1–2 nights in hospital.
