General Surgery

General Surgery is a broad and profound medical specialty, representing the cornerstone and foundation upon which all other surgical specialties were built. Contrary to what its name might suggest, general surgery is not “simple” or “unspecialized,” but rather a complex specialty that requires a surgeon to have extensive knowledge of anatomy, physiology, pathology, and critical care. A general surgeon is a physician who possesses the superior skill to deal with a wide range of surgical conditions, especially those affecting the abdomen and its contents, in addition to other areas such as the breast, endocrine glands, and skin and soft tissues. The world of general surgery is a world of crucial decisions and extreme precision, where the surgeon intervenes to repair what has been damaged by disease or injury, restore function, relieve pain, and save lives.

In this comprehensive article, we will delve into the depths of the general surgery specialty, to explore its precise definition and wide scope of work, and we will review in detail the most famous surgical procedures that fall under it, and learn about the modern surgical techniques used. We will also shed light on the sub-specialties that branched from it, and map out the patient’s journey with it, thus providing an integrated guide to this pivotal and vital medical specialty.

?What Is General Surgery

In the world of medicine, general surgery is defined as the surgical specialty that focuses primarily on treating diseases and injuries affecting the contents of the abdominal cavity, including the esophagus, stomach, small and large intestines, liver, pancreas, gallbladder, and spleen. In addition, the scope of general surgery extends to include the treatment of breast diseases, endocrine disorders (such as the thyroid and parathyroid glands), hernia repair, skin and soft tissue surgery, and trauma and emergency surgery. The general surgeon is trained to provide complete care to the patient, starting from diagnosis, through pre- and post-operative care, and ending with the management of potential complications, which makes them a multi-skilled physician capable of dealing with a variety of surgical challenges.

Fields of General Surgery

The scope of work and expertise of a general surgery specialist is very wide, and covers many vital body systems, which makes them a pivotal physician in any hospital:

• Digestive System: This system constitutes the largest part of general surgery practice, as surgeons treat diseases of the esophagus, stomach, small intestine, colon, rectum, and anus, including tumors, inflammations, and obstructions.
• Abdomen and its contents: The general surgeon deals with all abdominal organs, and performs operations such as gallbladder removal, hernia repair of all types, spleen removal, and treatment of pancreatic and liver diseases.
• Breast Surgery: General surgery specialists diagnose and treat breast diseases, including the removal of benign and malignant lumps (cancerous tumors), and performing procedures such as lumpectomy or complete mastectomy.
• Endocrine Surgery: This branch of general surgery involves performing operations on endocrine glands, the most famous of which are total or partial thyroidectomy, parathyroidectomy, and adrenalectomy.
• Skin and Soft Tissues: The general surgeon treats a variety of conditions affecting the skin and the tissues beneath it, such as the removal of fatty cysts, skin tumors, and the treatment of severe abscesses and inflammations.
• Trauma and Critical Care Surgery: The general surgeon is the first person responsible for evaluating and treating patients with accidents and severe injuries. This aspect of general surgery requires making quick decisions to perform emergency operations to stop bleeding and repair injured organs.
• Laparoscopic Surgery: Most general surgeons have become skilled in using minimally invasive surgical techniques (laparoscopy), which use small incisions and a camera to perform many operations, which reduces pain and speeds up recovery.

Most Famous General Surgery Operations

There is a group of surgical procedures that are at the core of the practice of the general surgery specialty, and are performed frequently in hospitals around the world, the most important of which are:

Appendectomy

The appendectomy is one of the most common emergency operations in the field of general surgery. It involves the surgical removal of the appendix, a small tube attached to the large intestine, when it becomes inflamed and swollen:

• Indications for the procedure: The only reason is acute appendicitis, which is a medical emergency, as a delay in treatment can lead to the appendix rupturing and the infection spreading in the abdomen (peritonitis).
• Surgical technique: It can be performed in the traditional open method via a single incision in the lower right abdomen, or more commonly today via laparoscopic surgery, which uses several small incisions to insert a camera and precise instruments.
• Recovery: Recovery after laparoscopic surgery is much faster, as the patient can return home within a day or two, and return to normal activities within one to two weeks.

Cholecystectomy

It is a surgical procedure to remove the gallbladder, a small organ located under the liver that stores bile. This operation has become one of the safest and most common procedures in general surgery thanks to laparoscopic technique:

• Indications for the procedure: The most common reason is the presence of gallstones that cause repeated pain (biliary colic) or acute inflammation. It is also performed to treat gallbladder polyps or its dysfunction.
• Surgical technique: The gold standard today is laparoscopic cholecystectomy, which is performed through four small incisions in the abdomen. Open surgery is rarely resorted to, except in cases of severe inflammation or the presence of adhesions.
• Recovery: Most patients can return home on the same day or the day after the surgery, and can gradually resume their normal diet, as the body adapts to the absence of the gallbladder.

Hernia Repair

 A hernia is the bulging of an organ or tissue through a weak point in the surrounding muscles or tissues. Hernia repair surgery is one of the basic operations in the specialty of general surgery:

• Indications for the procedure: Surgery is performed to relieve pain and discomfort, and to prevent serious complications such as a “strangulated” hernia, where the bulging tissue becomes trapped and its blood flow is cut off, which is an emergency condition.
• Surgical technique: A hernia can be repaired by open surgery, where the surgeon makes an incision directly over the hernia and returns the tissue to its place, and then strengthens the muscle wall with sutures or by installing a synthetic mesh. It can also be performed laparoscopically, which is characterized by smaller incisions and less pain.
• Recovery: Recovery depends on the size of the hernia and the technique used. In general, the patient is advised to avoid lifting heavy objects for several weeks after surgery to allow the mesh to integrate with the tissues.

Colon and Rectal Surgery

This important branch of general surgery deals with diseases of the large intestine. Conditions such as colon cancer, severe diverticulitis, or Crohn’s disease may require the removal of part of the colon:

• Indications for the procedure: They include colorectal cancer, diverticulitis with complications (such as perforation or abscess), bowel obstruction, and Crohn’s disease or ulcerative colitis that does not respond to drug treatment.
• Surgical technique: The affected part of the colon is removed (Colectomy), and then the two healthy ends are reconnected. It can be performed by open surgery or laparoscopically. In some cases, the patient may need a colostomy bag temporarily or permanently.
• Recovery: It is considered one of the major surgeries that requires a hospital stay for several days. Recovery depends on the extent of the surgery and the patient’s general condition, and may take several weeks to months for a full return to activity.

Breast Surgery

Breast surgery is an integral part of general surgery practice, although some surgeons specialize in it precisely (breast oncology surgeons):

• Indications for the procedure: The most common reason is breast cancer, where the goal is to remove the cancerous tumor. It is also performed to remove large or painful benign lumps, or to reduce breast size in cases of severe enlargement.
• Surgical technique: It includes removing the tumor only with a margin of healthy tissue (Lumpectomy), or removing the entire breast (Mastectomy). Often some lymph nodes are removed from under the armpit to assess the extent of the disease spread.
• Recovery: Physical recovery depends on the type of operation, but it is often accompanied by psychological and emotional challenges that require great support for the patient.

Modern Techniques in General Surgery

The field of general surgery has witnessed tremendous development in the techniques used, which has led to improved outcomes and reduced patient suffering:

• Open Surgery: It is the traditional method that involves making one large surgical incision to access the target organ. This technique is still necessary in major and complex operations, or in cases of emergencies and injuries, or when laparoscopic surgery is not possible.
• Laparoscopic Surgery: This technique has revolutionized the practice of general surgery. It is based on using several small incisions (0.5-1 cm) to insert a thin tube equipped with a camera (the laparoscope) and precise surgical instruments. The surgeon sees a magnified, high-definition image of the internal organs on a screen, which allows them to perform the operation with precision.
• Robotic Surgery: It is the latest development in minimally invasive surgery. The surgeon sits at a separate control unit and controls very precise robotic arms that perform the surgery. This technique provides a magnified 3D view and greater freedom of movement for the instruments, which increases the surgeon’s accuracy, and is especially useful in complex operations in tight spaces.

Sub-specialties Evolving from General Surgery

Due to its wide scope, general surgery has led to the birth of many precise surgical sub-specialties, where a surgeon, after completing their basic training, chooses to focus on a specific field:

• Colorectal Surgery: Focuses on treating diseases of the colon, rectum, and anus.
• Trauma and Critical Care Surgery: Specializes in the surgical care of accident patients and surgical intensive care.
• Vascular Surgery: Deals with diseases of the arteries and veins.
• Pediatric Surgery: Focuses on treating surgical conditions in newborns, infants, and children.
• Transplant Surgery: Specializes in performing organ transplant operations such as the liver, kidneys, and pancreas.
• Surgical Oncology: Focuses on the surgical treatment of cancer.
• Bariatric and Metabolic Surgery: Specializes in surgical procedures for weight loss.

The Patient’s Journey with General Surgery

Undergoing a surgical procedure is an important experience in anyone’s life. The patient’s journey with general surgery includes three main stages, each of which requires special preparation and care:

• Pre-operative Stage: Preparation and Consultation: This stage begins with the diagnosis and meeting the surgeon. The surgeon will explain the nature of the condition, treatment options, the details of the proposed operation, and its risks and benefits. Medical tests will be performed to assess the patient’s fitness for surgery, and clear instructions will be given regarding stopping some medications and fasting before the operation.
• The Day of Surgery: What to expect? On the day of the operation, the patient is admitted to the hospital. The anesthesia team will assess the patient again before transferring them to the operating room. After anesthesia, the general surgery team performs the planned operation. After the surgery ends, the patient is transferred to the recovery room to be closely monitored until they wake up from anesthesia.
• Post-operative Stage: Recovery and Rehabilitation: This stage depends on the type of surgery. Pain is controlled using painkillers, and the patient is encouraged to move early to prevent blood clots. Clear instructions are given about wound care, diet, and permitted and prohibited activities upon discharge from the hospital, in addition to scheduling follow-up appointments.

Costs of General Surgery Operations

Financial costs are an important aspect when planning to undergo any procedure in the field of general surgery. The final bill is greatly affected by a set of variable factors, which makes it difficult to set a fixed and uniform price for any surgical procedure, as each case is unique:

Influential Factor on Cost	Simple Explanation
Type and complexity of the operation	The cost of a simple operation such as removing a fatty cyst is completely different from the cost of a complex operation such as removing a part of the colon.
Surgical technique used	Laparoscopic or robotic surgery is usually more expensive than traditional open surgery due to the advanced equipment used.
Surgeon and anesthesia team fees	The surgeon’s fees vary based on their experience and reputation, and the cost of anesthesia varies based on the duration of the operation and the type of anesthesia.
Type and location of the hospital	The costs of operations in major private hospitals in major cities are much higher than in government hospitals or those in smaller areas.
Length of hospital stay	Every day the patient spends in the hospital after the operation adds additional costs including accommodation, nursing care, and medications.
Tests, medications, and supplies	The costs include all tests performed before and after the surgery, in addition to the cost of any meshes or special tools used during the operation.
Insurance coverage	The health insurance plan and the percentage of coverage it provides are the decisive factor in determining the final amount the patient pays out of their own pocket.

Prices of General Surgery Operations

To provide a clearer picture of the potential expenses, here is a list of estimated prices for some common operations in the field of general surgery. It is very important to emphasize that these figures are averages that vary greatly based on the factors mentioned above, and they are mainly based on cost standards in the US healthcare system:
