Breast surgery may involve any of a variety of surgical procedures carried out on the breasts of women (generally) and men. These procedures may include removing a sample of tissue from a breasttumour (abnormal growth), as well as removing malignant (cancerous) tumours. Surgery may also include breast reconstruction following a mastectomy (breast removal) for breast cancer. The surgeons who perform this type of breast reconstruction may be breast oncology (cancer) surgeons or plastic surgeons. (Surgeons trained in both specialities are known as oncoplastic surgeons.) Some breast surgeons also do cosmetic breast surgery, including enlargement and reduction.moreDermatology is concerned with the diagnosis, treatment and prevention of diseases of the skin, hair, nails, oral cavity (mouth) and genitals. It is sometimes also involved in cosmetic care and enhancement.General surgery takes its name from general medicine, and is a surgical specialty focusing on the torso and abdominal organs. This may include the intestines comprising the oesophagus, stomach, small and large intestines, pancreas, liver, gallbladder and bile ducts. It also often deals with diseases and disorders involving the skin and breasts.moreLaparoscopic cholecystectomy is removal of the gallbladder with the aid of a camera inserted into the abdomen. A small incision is made in the abdominal wall near the navel, through which alaparoscope, a flexible lighted tube with a camera attached, is inserted to view the gallbladder. The surgery is carried out with instruments inserted in three other small cuts made in the right upper part of the abdomen. The gallbladder is then taken out through one of the incisions. Laparoscopic cholecystectomy is a minimally invasive technique that permits a shorter hospital stay and shorter recovery time with less pain.moreLaparoscopic surgery, also known as ‘keyhole surgery’, is carried out with the aid of a camera inserted into the abdomen or pelvis. A small incision is made in the abdominal wall through which alaparoscope, a flexible lighted tube with a camera attached, is inserted so that structures within the abdomen and pelvis can be examined. The abdominal cavity is made more visible by distending it with an absorbable gas, usually carbon dioxide. A number of major and minor surgeries may be carried out. A variety of tubes and long, narrow instruments can be inserted through the same incision in the skin, or via other small incisions, facilitating a number of procedures without the need for a large surgical incision. The surgeon uses these instruments to manipulate, cut and sew tissue. A number of procedures can be performed laparoscopically, including gallbladder removal (laparoscopic cholecystectomy), oesophageal surgery (laparoscopic fundoplication), colon surgery (laparoscopic colectomy), and surgery on the stomach and spleen. Most patients receive general anaesthetic during the procedure.moreA hernia is a sac or pouch of tissue formed by the peritoneum, the lining of the abdominal cavity. The sac protrudes through a hole or weak area in the fascia, the strong layer of the abdominal wallthat surrounds the muscle. Hernias occur in different places: femoral hernia (upper thigh); hiatial hernia (upper part of stomach); incisional hernia (can occur through a scar if you have had abdominal surgery); inguinal hernia (groin); umbilical hernia (around the navel). Surgery under general anaesthetic is used to permanently fix a hernia. The weakened abdominal wall tissue (fascia) is secured and any holes are closed. An umbilical hernia that fails to heal on its own by the time a child is five years old may be repaired. Emergency surgery for hernias is sometimes needed. In addition to open surgery, some hernias can be repaired using a laparoscope (flexible lighted tube tipped with a camera), which is less invasive.more
