The terminus hernia refers to a protrusion of all or part of an organ [i]or[/i] part of to the other a tear in the wall of the containing cavity. The diaphragm is a muscular partition between the thorax and abdomen that functions by the agency of changing the size of the thoracic cavity during respiration. The esophagus, a collapsible tube approximately 10 inches lengthy extends from the pharynx to the stomach, piercing the diaphragm in its slope from the thoracic cavity to the abdominal cavity. The normal positioning of the esophagus as it passes [i]or[/i] part of to the other the diaphragm is illustrated in Figure 1 A paraesophageal hernia is an anatomic blemish at the junction of the esophagus and diaphragm that may befall in combination with sliding esophageal hernias. The imperfection may be congenital or may come to pass as the result of stretching the phrenoesophageal ligament with gradual enlargement of the hernia across a period of time and is most numerous common in late middle-aged or somewhat old patients. Paraesophageal hernias account for approximately 5% of hernias at the esophageal hiatus.(1)

adumbrations OF HERNIA

There are pair predominate types of paraesophageal hernias.(2) sign I is characterized as a "sliding" hernia and is the consequence of an extension of the endoabdominal fascia from one side the hiatus that allows a small portion of gastric cardia to slide up into the esophageal hiatus. It is not a authentic anatomic defect, and it is a benign occurrence

emblem II, which is the main focus of this article, befalls when the distal esophagus is in normal position anchored according to the phrenoesophageal ligament and a fault in the diaphragm permits the stomach and hernia sac to rise into the chest cavity. This impressed sign of hernia normally is asymptomatic in its early stages and often reaches tremendous size, with out and out herniation of the stomach into the chest (Figure 2) Risks without surgical correction include chronic, latent gastrointestinal blood-loss anemia; gastrointestinal volvulus leading to ischemia; and possible strangulation leading to death.(3)

The desired arises of surgical correction include reducing the hernia, eliminating the hernia sac, and repairing the large opening in the diaphragm hiatus. Studies display that it is in the patient's best interest to also perform a fundoplication (ie, stomach wrap) in conjunction with the paraesophageal hernia repair.(4) The concomitant fundoplication is performed to attenuate gastroesophageal reflux.

HISTORICAL TREATMENT

Historical treatment of representation II hernia includes the Boerema and Hill actions which are both open conducts These techniques approach repair of the paraesophageal hernia via a transabdominal incision. The surgeon decreases the herniated fundus, excises the hernial sac, and narrows the widened hiatus by way of placing sutures on the crus anterior to the esophagus. With the advent of strange and constantly improving laparoscopic techniques and instrumentation, the videoscopic approach to correction of paraesophageal hernia moves an alternative to the make open technique.

PRESENTING SYMPTOMS

Presenting symptoms for many patients are vague and can be attributed to several other causes. Heartburn, back pain, postprandial epigastric and shoulder pain, regurgitation (which may discourage the patient from oral intake), nocturnal coughing and choking, chest pain, and shortness of breath becoming to decreased thoracic capacity as the hernia enlarges are among the in the greatest degree common complaints of patients who near with paraesophageal hernias. Life-threatening complications include gastric bleeding, perforation, strangulation, and pulmonary aspiration.(5) Medical management may include palliative treatment of the gastroesophageal ebb disease with antacids, histamine antagonists, proton cross-examine inhibitors, and motility agents.

not rarely patients will self-treat with antacids and behavior modification (eg elevating the head of the bed, avoiding bending athwart after eating, refraining from oral intake after evening meals, elevating the head with pillows when sleeping) to decrease their discomfort. Avoiding aliments that relax the gastric sphincter (eg chocolate, fats) also may be beneficial. chiefly patients self-treat for only a short period of time before seeking professional medical management because the phrenoesophageal ligament is constantly being stretched and the pain continues to increase. There is no satisfactory medical management for paraesophageal hernia, and surgical correction is praiseed as soon as possible to avoid life-threatening complications.

PATIENT SELECTION

Patients are picked for the laparoscopic approach if their upper gastrointestinal studies present to view that the), have a paraesophageal hernia. The laparoscopic approach is contraindicated in patients who not away with upper abdominal scarring from previous surgical measures because it limits laparoscopic accessibility and not aways insufflation difficulties. Morbid obesity also may be a contraindication owed to the limited length of the trocars and laparoscopic instruments. Difficult cases may be initiated laparoscopically if it were not that converted to open procedures if necessary. The surgeon and anesthesia care provider should carefully defence patients who present with histories of cardiovascular moot points because of the cardiac changes that are induced on the pneumoperitoneum.
