General Surgery
General surgery encompasses a broad range of procedures primarily focused on abdominal organs but also includes other areas of the body. General surgeons are trained to perform operations related to the digestive system, thyroid, and hernias, among others.
Appendectomy
Application: Removal of the appendix, often due to appendicitis.
Indications: Acute appendicitis characterized by inflammation, infection, or rupture of the appendix.
Procedure Details: Typically performed laparoscopically, involving small incisions and the use of a camera to remove the appendix.
Recovery: Generally quick, with patients often discharged within 24-48 hours post-surgery if uncomplicated.
Cholecystectomy
Application: Removal of the gallbladder.
Indications: Gallstones causing pain, cholecystitis, or pancreatitis.
Procedure Details: Can be performed laparoscopically (minimally invasive) or through an open incision, depending on complexity.
Recovery: Minimally invasive procedures allow for same-day discharge; open surgery may require a longer hospital stay.
Hernia Repair
Application: Correction of hernias, which occur when an organ or tissue protrudes through a weakness in the surrounding muscle or connective tissue.
Indications: Inguinal, umbilical, incisional hernias, among others.
Procedure Details: Techniques include open repair or laparoscopic methods, often using mesh to reinforce the area.
Recovery: Varies by procedure type; laparoscopic repairs typically offer faster recovery times.
Mastectomy
Application: Removal of one or both breasts, partially or completely.
Indications: Breast cancer, prophylactic measures in high-risk individuals.
Procedure Details: Can be simple (removal of breast tissue) or radical (including chest wall muscles).
Recovery: Involves wound care and, if reconstructive surgery is planned, additional procedures.
Orthopedic Surgery
Orthopedic surgery deals with conditions involving the musculoskeletal system. Orthopedic surgeons treat injuries and diseases affecting bones, joints, ligaments, tendons, and muscles.
Total Knee Replacement
