Incisional hernia
Specialty General surgery

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.

Signs and symptoms

Clinically, incisional hernias present as a bulge or protrusion at or near the area of a surgical incision. Virtually any prior abdominal operation can develop an incisional hernia at the scar area (provided adequate healing does not occur due to infection), including large abdominal procedures such as intestinal or vascular surgery, and small incisions, such as appendix removal or abdominal exploratory surgery. While incisional hernias can occur at any incision, they tend to occur more commonly along a straight line from the xiphoid process of the sternum straight down to the pubis, and are more complex in these regions. Hernias in these areas have a high rate of recurrence if repaired via a simple suture technique under tension. For this reason, it is especially advised that these be repaired via a tension free repair method using a synthetic mesh.

Cause

Incisional hernias are usually caused by a weakness of the surgical wounds, which may be caused by hematoma, seroma, or infection, all of which result in decreased wound healing. They may also be caused by increased intra-abdominal pressure due to a chronic cough (as in COPD), constipation, urinary obstruction (as in BPH), pregnancy, or ascites. They can also result from poor surgical technique.

Treatment

Traditional "open" repair of incisional hernias can be quite difficult and complicated. The weakened tissue of the abdominal wall is re-incised and a repair is reinforced using a prosthetic mesh. Complications, particularly infection of the incision, frequently occur because of the large size of the incision required to perform this surgery. A mesh infection after this type of hernia repair most frequently requires a complete removal of the mesh and ultimately results in surgical failure. In addition, large incisions required for open repair are commonly associated with significant postoperative pain. Reported recurrence rates after open repair are up to 20% [1] [2] and influenced by mesh size and fixation type. [3] [4] [5] [6]

Regeneration by autologous tissue stem cells is a unique method for repair of large incisional hernias. It not only obviates causative factors responsible for herniation but utilises these factors to strengthen repair and regeneration of traumatised tissues. [7] [8]

Laparoscopic incisional hernia repair is a new method of surgery for this condition. [9] [10] [11] The operation is performed using surgical microscopes and specialized instruments. The surgical mesh is placed into the abdomen underneath the abdominal muscles through small incisions to the side of the hernia. In this manner, the weakened tissue of the original hernia is never re-incised to perform the repair, and one can minimize the potential for wound complications such as infections. In addition, performance of the operation through smaller incisions can make the operation less painful and speed recovery. Laparoscopic repair has been demonstrated to be safe and a more resilient repair than open incisional hernia repair.

It is uncertain whether wound drains insertion after incisional hernia repair is associated with better outcomes. [12]

A hiatal hernia or hiatus hernia is a type of hernia in which abdominal organs slip through the diaphragm into the middle compartment of the chest. This may result in gastroesophageal reflux disease (GERD) or laryngopharyngeal reflux (LPR) with symptoms such as a taste of acid in the back of the mouth or heartburn. Other symptoms may include trouble swallowing and chest pains. Complications may include iron deficiency anemia, volvulus, or bowel obstruction.

Hernia repair is a surgical operation for the correction of a hernia—a bulging of internal organs or tissues through the wall that contains it. It can be of two different types: herniorrhaphy; or hernioplasty. This operation may be performed to correct hernias of the abdomen, groin, diaphragm, brain, or at the site of a previous operation. Hernia repair is often performed as an ambulatory procedure.

An umbilical hernia is a health condition where the abdominal wall behind the navel is damaged. It may cause the navel to bulge outwards—the bulge consisting of abdominal fat from the greater omentum or occasionally parts of the small intestine. The bulge can often be pressed back through the hole in the abdominal wall, and may "pop out" when coughing or otherwise acting to increase intra-abdominal pressure. Treatment is surgical, and surgery may be performed for cosmetic as well as health-related reasons.

<span class="mw-page-title-main">Bowel resection</span> Surgical procedure in which a part of an intestine is removed

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.

<span class="mw-page-title-main">Diastasis recti</span> Medical condition

Diastasis recti, or rectus abdominis diastasis, is defined as a gap of about 2.7 cm or greater between the two sides of the rectus abdominis muscle. The distance between the right and left rectus abdominis muscles is created by the stretching of the linea alba, a connective collagen sheath created by the aponeurosis insertions of the transverse abdominis, internal oblique, and external oblique. This condition has no associated morbidity or mortality. Physical therapy is often required to repair this separation and surgery is an option for more severe cases. Standard exercise rarely results in complete healing of the separated muscles.

<span class="mw-page-title-main">Obturator hernia</span> Medical condition

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.

Single-incision laparoscopic surgery (SILS) is an advanced, minimally invasive (keyhole) procedure in which the surgeon operates almost exclusively through a single entry point, typically the patient's umbilicus (navel). Special articulating instruments and access ports eliminate the need to place trochars externally for triangulation, thus allowing the creation of a small, solitary portal of entry into the abdomen.

De Garengeot's hernia is a rare subtype of an incarcerated femoral hernia. This eponym may be used to describe the incarceration of the vermiform appendix within a femoral hernia. This mechanism is contrasted with the Amyand hernia, in which the appendix protrudes through an inguinal hernia.

<span class="mw-page-title-main">Surgical mesh</span> Material used in surgery

Surgical mesh is a medical implant made of loosely woven mesh, which is used in surgery as either a permanent or temporary structural support for organs and other tissues. Surgical mesh can be made from both inorganic and biological materials and is used in a variety of surgeries, although hernia repair is the most common application. It can also be used for reconstructive work, such as in pelvic organ prolapse or to repair physical defects created by extensive resections or traumatic tissue loss.
