This is an investigator initiated pilot study to observe the short-term outcomes (a follow-up
period of up to six months) of patients who undergo a laparoscopic paraesophageal Hiatal
hernia (PEH) repair using the Veritas® Collagen Matrix brand biological mesh. This is a
preliminary study at the University of Washington.
A PEH occurs when the stomach protrudes through the diaphragm next to the esophagus. The
chance of recurrence of a Hiatal hernia after laparoscopic PEH repair is between 20-40%
within 6 months.During laparoscopic PEH repair, a mesh-type product is used as a scaffold.
The mesh serves as a reinforcing material during the surgical repair. It is cut to the
appropriate size needed for the hernia and sutured to the surrounding diaphragmatic tissue.
There are many different types of meshes available on the market, and vary in the degree of
manageability, strength, and adherence.
Although surgical meshes work on the same principal, the variance between materials may
affect patient outcomes. There is evidence that a biologic mesh, specifically one derived
from Small Intestinal Submucosa (SIS), decreases the short-term (6-month) recurrence rates
compared to a synthetic mesh or another type of biologic mesh. A biologic mesh, serving as a
scaffold, will be replaced by the patient's own tissue after about 6 months. Theoretically,
this would prevent the possible complications associated with synthetic mesh including mesh
erosion into the esophagus or stricture of the esophagus.
There are some case series showing similar short-term results between the different biologic
meshes, but there is no direct comparative data.

Eligibility |
Inclusion Criteria: A. Subjects must have a documented symptomatic paraesophageal hernia that: - 1. Is greater than 5 cm hiatal hernia on Upper Gastrointestinal (UGI) series - 2. Has evidence that the stomach or other viscera is present in the hernia and does not spontaneously reduce from the mediastinum - 3. Has significant symptoms or signs of a paraesophageal hernia: heartburn, dysphagia, chest pain, shortness of breath, post-prandial abdominal pain, early satiety, odynophagia or chronic anemia B. Consenting adult =18 years ~ documentation of informed consent will be recorded in the research records C. Must be able to participate in follow-up evaluations (subjects must be fully cognitive) D. Has a telephone E. Free of cognitive or speech impairment Exclusion Criteria: A. Previous operation of the esophagus or stomach B. Associated gastrointestinal diseases that require extensive medical or surgical intervention that might interfere with quality of life assessment (e.g. Crohn's disease) C. Emergent operation for acute volvulus (twisting/rotation of the bowel leading to obstruction) |

Primary | Recurrence Rate of Hiatal Hernia Rate Based on Upper Gastrointestinal (UGI) Series | Number of subjects experiencing recurrence greater than 2cm as well as 5cm post surgery. | 6 months post procedure | |
Secondary | Pre and Post-operative Symptoms | Heartburn frequency Pre and Post-operative was measured using the Paraesophagel Hernia Patient Questionnaire-Visual analog score (VAS). The VAS measures subjective characteristics that specify the respondents level of agreement to a statement. In this questionnaire, the patient indicated how frequent they had Heartburn. The Heartburn frequency measurement scale: 0=Never, 1=once/month,2=once/week,3=once/day,4=several/day. The lower the VAS score the better the outcome meaning less episodes of Heartburn. The Heartburn VAS score was measured pre-operative and post-operative. The comparison of Heartburn VAS score pre-operative and post-operative indicated that participants experienced Improvement and No Improvement. |
Pre-surgery and 6 month follow up | |
Secondary | Pre and Post-operative Symptoms | Regurgitation frequency Pre and Post-operative was measured using the Paraesophagel Hernia Patient Questionnaire-Visual analog score (VAS). The VAS measures subjective characteristics that specify the respondents level of agreement to a statement. In this questionnaire, the patient indicated how frequent they had Regurgitation. The Regurgitation frequency measurement scale: 0=Never, 1=once/month,2=once/week,3=once/day,4=several/day. The lower the VAS score the better the outcome meaning less episodes of Regurgitation. The Regurgitation VAS score was measured pre-operative and post-operative. The comparison of Regurgitation VAS score pre-operative and post-operative indicated that participants experienced Improvement and No Improvement. |
Pre-surgery and 6 month follow up | |
Secondary | Pre and Post-operative Symptoms | Dysphagia frequency Pre and Post-operative was measured using the Paraesophagel Hernia Patient Questionnaire-Visual analog score (VAS). The VAS measures subjective characteristics that specify the respondents level of agreement to a statement. In this questionnaire, the patient indicated how frequent they had Dysphagia. The Dysphagia frequency measurement scale: 0=Never, 1=once/month,2=once/week,3=once/day,4=several/day. The lower the VAS score the better the outcome meaning less episodes of Dysphagia. The Dysphagia VAS score was measured pre-operative and post-operative. The comparison of Dysphagia VAS score pre-operative and post-operative indicated that some participants experienced Improvement and others worsen. |
