Discussion/General Information

PEH is a type of hiatal hernia, which is a protrusion of an abdominal structure, other than the esophagus, into the chest cavity. Hiatal hernias are categorized into Types I – IV. The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) published guidelines for the management of hiatal hernia (Kohn, 2013) with the following classifications:

Type I hernias are sliding hiatal hernias, where the gastroesophageal junction migrates above the diaphragm. The stomach remains in its usual longitudinal alignment and the fundus remains below the gastroesophageal junction.Type II hernias are pure paraesophageal hernias (PEH); the gastroesophageal junction remains in its normal anatomic position but a portion of the fundus herniates through the diaphragmatic hiatus adjacent to the esophagus.Type III hernias are a combination of Types I and II, with both the gastroesophageal junction and the fundus herniating through the hiatus. The fundus lies above the gastroesophageal junction.Type IV hiatal hernias are characterized by the presence of a structure other than stomach, such as the omentum, colon or small bowel within the hernia sac.

The majority of hiatal hernias are Type I, which are sliding hiatal hernias. Types II – IV are considered PEH with Type III being the most common and Type II being the least common.

PEH can be repaired through an open or laparoscopic transabdominal approach or through thoracotomy. Due to less postoperative pain, reduced rate of morbidity, and shorter hospital stays, SAGES recommends laparoscopic repair as the preferred method (Kohn, 2013). Several retrospective studies resulted in similar conclusions (Boushey, 2008; Dallemagne, 2011; El Khoury, 2015; Kubasiak, 2014). Other surgical procedures that are sometimes used in addition to PEH repair include hernia sac excision, reinforced repair with the use of mesh, fundoplication, mediastinal dissection of the esophagus, Collis gastroplasty, gastropexy, and gastrostomy tube insertion. The literature on these technical considerations consists of mainly low quality retrospective reports with small sample sizes and inadequate study designs.

Past studies have suggested PEH repair for both symptomatic and asymptomatic PEH; however, more recent studies indicate that PEH repair should only be performed in individuals with gastric outlet obstruction, severe gastroesophageal reflux, severe anemia, or possible gastric strangulation since asymptomatic PEH is safe to observe. In addition, PEH repair in asymptomatic individuals can decrease the quality-adjusted life expectancy for those aged 65 years and older (Kohn, 2013). For individuals with gastroesophageal reflux, the American College of Gastroenterology recommends non-surgical management of gastroesophageal reflux before surgical treatment. Interventions in the management of gastroesophageal reflux include weight loss counseling and attempting weight loss, head of bed elevation, avoidance of meals 2 to 3 hours before bedtime, elimination of foods that trigger reflux (for example, chocolate, caffeine, acidic foods, and spicy foods), tobacco and alcohol cessation, optimizing proton pump inhibitor therapy, excluding other etiologies, and reflux monitoring (Katz, 2013). Recurrent PEH repair is indicated when the symptoms match anatomical findings (Kohn, 2013), which occurs in 25.5% of primary PEH repairs (Rathore, 2007).

Some retrospective studies have reported gastroesophageal reflux as a complication after bariatric surgery that can lead to reoperation and concluded that hiatal hernias should be repaired if detected during these procedures (Dolan, 2003; El Chaar, 2016; Frezza, 2008). Another larger retrospective study (Gulkarov, 2008) reviewed charts of all individuals over a 5-year period who had laparoscopic adjustable gastric banding (n=1298) with an average follow-up of 24.8 months, and those who had laparoscopic adjustable gastric banding with concurrent hiatal hernia repair (n=520) with an average follow-up of 20.5 months. The authors found that adding hiatal hernia repair to laparoscopic adjustable gastric banding resulted in a significant reduction in the number of reoperations for band slippage, pouch dilation, and hiatal hernia (pDefinitions

Anemia: A condition of having too few red blood cells. Healthy red blood cells carry oxygen throughout the body. If the blood is low on red blood cells, the body does not get enough oxygen.

Collis gastroplasty: A surgical procedure to lengthen the esophagus.

Fundoplication: A surgical procedure designed to restore the barrier function of the lower esophageal sphincter. The most common type of fundoplication procedure is referred to as Nissen fundoplication, which is typically performed laparoscopically.

Gastric banding: This surgical procedure is intended to help a person lose weight. A band is placed around the upper part of the stomach, creating a small pouch that can hold only a small amount of food. The narrowed opening between the stomach pouch and the rest of the stomach controls how quickly food passes from the pouch to the lower part of the stomach. This system helps the person to eat less by limiting the amount of food that can be eaten at one time and increasing the time it takes for food to be digested.

Gastric bypass: This surgical procedure reduces the stomach capacity and diverts partially digested food from the duodenum to the jejunum (section of the small intestine extending from the duodenum).

Gastric outlet obstruction: A condition caused by any disease process that blocks emptying of the stomach.

Gastric strangulation: A condition caused by a hernia that cuts off blood supply to the intestines and tissues in the abdomen.

Gastroesophageal reflux: A condition caused by chronic back-flow of acid from the stomach into the esophagus, causing heartburn and leading to irritation and possible damage to the lining of the esophagus.

Gastropexy: A surgical procedure designed to suture the stomach to the abdominal wall.

Thoracotomy: A surgical procedure to open and access an individual’s chest.
