Laparoscopy is an operation performed in the abdomen or pelvis using small incisions with the aid of a camera. The laparoscope aids diagnosis or therapeutic interventions with a few small cuts in the abdomen.
A hernia is the abnormal exit of tissue or an organ, such as the bowel, through the wall of the cavity in which it normally resides. Various types of hernias can occur, most commonly involving the abdomen, and specifically the groin. Groin hernias are most commonly of the inguinal type but may also be femoral. Other types of hernias include hiatus, incisional, and umbilical hernias. Symptoms are present in about 66% of people with groin hernias. This may include pain or discomfort in the lower abdomen, especially with coughing, exercise, or urinating or defecating. Often, it gets worse throughout the day and improves when lying down. A bulge may appear at the site of hernia, that becomes larger when bending down. Groin hernias occur more often on the right than left side. The main concern is bowel strangulation, where the blood supply to part of the bowel is blocked. This usually produces severe pain and tenderness in the area. Hiatus, or hiatal hernias often result in heartburn but may also cause chest pain or pain while eating.
Bowel obstruction, also known as intestinal obstruction, is a mechanical or functional obstruction of the intestines which prevents the normal movement of the products of digestion. Either the small bowel or large bowel may be affected. Signs and symptoms include abdominal pain, vomiting, bloating and not passing gas. Mechanical obstruction is the cause of about 5 to 15% of cases of severe abdominal pain of sudden onset requiring admission to hospital.
Diverticulitis, also called colonic diverticulitis, is a gastrointestinal disease characterized by inflammation of abnormal pouches—diverticula—that can develop in the wall of the large intestine. Symptoms typically include lower-abdominal pain of sudden onset, but the onset may also occur over a few days. There may also be nausea; and diarrhea or constipation. Fever or blood in the stool suggests a complication. Repeated attacks may occur.
A volvulus is when a loop of intestine twists around itself and the mesentery that supports it, resulting in a bowel obstruction. Symptoms include abdominal pain, abdominal bloating, vomiting, constipation, and bloody stool. Onset of symptoms may be rapid or more gradual. The mesentery may become so tightly twisted that blood flow to part of the intestine is cut off, resulting in ischemic bowel. In this situation there may be fever or significant pain when the abdomen is touched.
A Gastrostomy is the creation of an artificial external opening into the stomach for nutritional support or gastric decompression. Typically this would include an incision in the patient's epigastrium as part of a formal operation. When originally devised over a century ago the procedure was completed through open surgery using the Stamm technique. It can be performed through surgical approach, percutaneous approach by interventional radiology, percutaneous endoscopic gastrostomy (PEG) or percutaneous ultrasound gastrostomy (PUG).
Robot-assisted surgery or robotic surgery are any types of surgical procedures that are performed using robotic systems. Robotically assisted surgery was developed to try to overcome the limitations of pre-existing minimally-invasive surgical procedures and to enhance the capabilities of surgeons performing open surgery.
A Spigelian is the type of ventral hernia where aponeurotic fascia pushes through a hole in the junction of the linea semilunaris and the arcuate line creating a bulge. It appears in the abdomen lower quadrant between an area of dense fibrous tissue and abdominal wall muscles causing a.
Femoral hernias occur just below the inguinal ligament, when abdominal contents pass through a naturally occurring weakness in the abdominal wall called the femoral canal. Femoral hernias are a relatively uncommon type, accounting for only 3% of all hernias. While femoral hernias can occur in both males and females, almost all develop in women due to the increased width of the female pelvis. Femoral hernias are more common in adults than in children. Those that do occur in children are more likely to be associated with a connective tissue disorder or with conditions that increase intra-abdominal pressure. Seventy percent of pediatric cases of femoral hernias occur in infants under the age of one.
An incisional hernia is a type of hernia caused by an incompletely-healed surgical wound. Since median incisions in the abdomen are frequent for abdominal exploratory surgery, ventral incisional hernias are often also classified as ventral hernias due to their location. Not all ventral hernias are from incisions, as some may be caused by other trauma or congenital problems.
A bowel resection or enterectomy is a surgical procedure in which a part of an intestine (bowel) is removed, from either the small intestine or large intestine. Often the word enterectomy is reserved for the sense of small bowel resection, in distinction from colectomy, which covers the sense of large bowel resection. Bowel resection may be performed to treat gastrointestinal cancer, bowel ischemia, necrosis, or obstruction due to scar tissue, volvulus, and hernias. Some patients require ileostomy or colostomy after this procedure as alternative means of excretion. Complications of the procedure may include anastomotic leak or dehiscence, hernias, or adhesions causing partial or complete bowel obstruction. Depending on which part and how much of the intestines are removed, there may be digestive and metabolic challenges afterward, such as short bowel syndrome.
Tubal reversal, also called tubal sterilization reversal, tubal ligation reversal, or microsurgical tubal reanastomosis, is a surgical procedure that can restore fertility to women after a tubal ligation. By rejoining the separated segments of the fallopian tube, tubal reversal can give women the chance to become pregnant again. In some cases, however, the separated segments cannot actually be reattached to each other. In some cases the remaining segment of tube needs to be re-implanted into the uterus. In other cases, when the end of the tube has been removed, a procedure called a neofimbrioplasty must be performed to recreate a functional end of the tube which can then act like the missing fimbria and retrieve the egg that has been released during ovulation.
A surgical suture, also known as a stitch or stitches, is a medical device used to hold body tissues together and approximate wound edges after an injury or surgery. Application generally involves using a needle with an attached length of thread. There are numerous types of suture which differ by needle shape and size as well as thread material and characteristics. Selection of surgical suture should be determined by the characteristics and location of the wound or the specific body tissues being approximated.
An obturator hernia is a rare type of hernia, encompassing 0.07-1% of all hernias, of the pelvic floor in which pelvic or abdominal contents protrudes through the obturator foramen. The obturator foramen is formed by a branch of the ischial as well as the pubic bone. The canal is typically 2-3 centimeters long and 1 centimeters wide, creating a space for pouches of pre-peritoneal fat.
Pyloromyotomy is a surgical procedure in which a portion of the muscle fibers of the pyloric muscle are cut. This is typically done in cases where the contents from the stomach are inappropriately stopped by the pyloric muscle, causing the stomach contents to build up in the stomach and unable to be appropriately digested. The procedure is typically performed in cases of "hypertrophic pyloric stenosis" in young children. In most cases, the procedure can be performed with either an open approach or a laparoscopic approach and the patients typically have good outcomes with minimal complications.
Single-port laparoscopy (SPL) is a recently developed technique in laparoscopic surgery. It is a minimally invasive surgical procedure in which the surgeon operates almost exclusively through a single entry point, typically the patient's navel. Unlike a traditional multi-port laparoscopic approach, SPL leaves only a single small scar.
Inguinal hernia surgery is an operation to repair a weakness in the abdominal wall that abnormally allows abdominal contents to slip into a narrow tube called the inguinal canal in the groin region.
A morcellator is a surgical instrument used for division and removal of large masses of tissues during laparoscopic surgery. In laparoscopic hysterectomy the uterus is cut up in strips, or morcellated, into smaller pieces inside the patient's abdominal cavity in order to extract from the abdomen. It can consist of a hollow cylinder that penetrates the abdominal wall, ending with sharp edges or cutting jaws, through which a grasper can be inserted to pull the mass into the cylinder to cut out an extractable piece.
Vaginal evisceration is an evisceration of the small intestine that occurs through the vagina, typically subsequent to vaginal hysterectomy, and following sexual intercourse after the surgery. It is a surgical emergency.
Surgical knots (ligatures) are the knots used to bind suture materials together while binding tissue in surgery. They are used in medical and veterinary settings.
