Concomitant Paraesophageal Parahiatal Hernia: a Rare Entity

Paraesophageal hernia (PEH) is herniation of fundus of the stomach or very rarely other abdominal structures like colon/spleen through a hiatal opening in the diaphragm, usually towards the left side. PEH comprises about 3.5–5% of all hiatal hernias. They are more common in elderly population. Laparoscopic management of PEH is the preferred treatment of choice especially in elderly patients. The concomitant occurrence of parahiatal hernia (PH) with PEH is a very rare scenario with only a handful number of cases reported in the literature. A 72-year lady patient presented to us with chief complaints of pain abdomen in the right upper quadrant region and vomiting intermittently for the last 6 months. Upper GI endoscopy showed the presence of hiatal hernia with GE junction at 37 cm. The patient underwent laparoscopic repair of hiatus and paraesophageal hernia. The pre-operative diagnosis of PH is difficult, a laparoscopic approach is helpful both as a diagnostic as well as therapeutic tool for treatment of PH. The various things to keep in mind while dealing with such rare cases are the patient’s profile, symptoms, expected complications and outcomes.

Changes in esophageal physiology after paraesophageal hernia repair and Collis gastroplasty.

The surgical approach and technique for paraesophageal hernia (PEH) repair is much debated. The changes in the esophageal physiology after PEH repair with a concomitant Collis gastroplasty (PEH-CG) are not clearly known. The aim of this study was to determine the changes in high resolution esophageal manometry (HREM) and esophageal pH testing after PEH-CG. Retrospective analysis of all patients who underwent PEH-CG at our institution between 2006 and 2013 was performed. Patients had esophageal pH testing, HREM, barium swallow and an upper endoscopy before and after PEH-CG. A total of 182 patients underwent PEH-CG during the study period. Majority of patients had Nissen fundoplication (176, 96.7%) with Toupet in 6 (3.3%). Basal lower esophageal sphincter pressure (LESP) was lower after fundoplication (20.3mmHg ± 11.3 vs. 25.8mmHg ± 15.6, p < 0.001), whereas residual LESP was noted to be higher after fundoplication (7.7mmHg ± 4.9 vs. 6.1mmHg ± 6.7, p < 0.009). There were no significant changes in the esophageal motility patterns. There was an improvement in total pH and upright pH but not supine pH post PEH-CG. Normalization of total acid exposure after fundoplication was noted in 31 (59.6%) of the 52 patients who had abnormal total acid exposure prior to fundoplication. Objective clinical assessment in patients undergoing PEH-CG demonstrates an effective operation for this complex problem. There was an increase in residual LESP but interestingly, decrease in basal LESP. Additionally, there was an improvement in esophageal acid exposure afterwards. These findings will facilitate future management of PEH.

Paraesophageal Hernia and Reflux Prevention: Is One Fundoplication Better than the Other?

The management of paraesophageal hernia (PEH) is one of the most debated in surgery. Trends regarding indications, approach (open, laparoscopic, thoracoscopic), sac excision, mesh placement, and routine performance of fundoplication have changed over time. Today, most surgeons tend to perform a laparoscopic PEH repair that entails the excision of the sac, liberal use of a mesh to buttress the hiatus, and the addition of an anti-reflux procedure. Nevertheless, very little has been written on which type of fundoplication should be performed in these patients. Therefore, the goal of our study was to provide an evidence-based overview of which type of fundoplication should be performed during a PEH repair and the role of preoperative function tests in the decision-making METHODS: We searched the MEDLINE, Cochran, PubMed, Google Scholar, and Embase databases for papers published between 1996 and 2016 pertaining to the surgical treatment of PEH. We hand-searched the bibliographies of included studies and we excluded all reviews and case reports. We selected clinical studies and technical reports. We only considered papers stating rationales for the type of fundoplication performed. Our search yielded 24 articles: 17 clinical studies and 7 technical reports. In five of the clinical studies, a fundoplication was added only to patients with reflux symptoms. In all clinical studies, the most performed procedure was a total fundoplication (Nissen or Nissen-Rossetti), whereas a partial fundoplication (Toupet more frequently than Dor) or no fundoplication was reserved to those with impaired esophageal motility. All seven technical reports recommended a tailored approach and suggested adding a partial fundoplication (mainly Toupet) when the manometric findings showed esophageal dismotility. The argument of whether or not a fundoplication should be added to a PEH repair in patients without evidence of reflux still persists. However, this review highlights that, when a fundoplication is performed, a tailored approach based on preoperative function tests is almost always preferred.

Surgical Treatment of Paraesophageal Hernias: A Review.

The management of paraesophageal hernia (PEH) can be challenging due to the lack of consensus regarding indications and principles of operative treatment. In addition, data about the pathophysiology of the hernias are scant. Therefore, the goal of this review is to shed light and describe the classification, pathophysiology, clinical presentation, and indications for treatment of PEHs, and provide an overview of the surgical management and a description of the technical principles of the repair.

Age and BMI Should Not Preclude Elective Pararesophageal Hernia Repair

Introduction: There has been a paradigm shift in the management of paraesophageal hernias (PEH), in that elective surgical repair is usually limited to symptomatic patients. These operations represent a considerable technical challenge in patients who are older and have multiple comorbidities, especially in comparison to patients undergoing operations for gastroesophageal reflux disease (GERD). Given the modified indications for repair of PEHs, it is necessary to identify factors that are associated with increased rates of mortality and morbidity and to determine exclusion criteria, if any, to optimize outcomes in these complex patients.

Characterization and management of paraesophageal hernias in children after antireflux operation

Purpose: The aim of this study was to determine the important factors in the development and subsequent treatment of postoperative paraesophageal hernia (PPEH). Methods: A retrospective analysis was performed in 464 consecutive children (ages 3 days to 18 years) for PPEH after a primary antireflux operation performed at a Children's Hospital and University Hospital between 1985 and 1997. All operations included a crural repair, but the Nissen fundoplication was performed with (n = 162) and without (n = 70) plication of the esophagus to the crus at 3 points. Patients with and without PPEH were compared with respect to the type of antireflux operation, the patient's age at operation, and the preoperative and postoperative clinical courses. A preoperative corrected gastric emptying value was obtained from a radionuclide gastric emptying study in 289 patients. The treatment of PPEH also was examined. Results: The incidence of PPEH in our patients was 4.5% (21 of 464). Although there was a lower incidence of PPEH in patients with crural plication compared with patients without crural plication during Nissen fundoplication (5 of 162, 3% v 7 of 70, 10%; P = .035), 2 patients with crural plication had a postoperative esophageal leak. Patients with PPEH had a significantly increased prevalence of gagging before the initial antireflux operation compared with patients without PPEH (3 of 21, 14.3% v 7 of 443, 1.6%; P = .007). A higher prevalence of slow corrected gastric emptying preoperatively also was seen in patients with PPEH compared with patients without PPEH (8 of 15, 53% v 79 of 274, 29%; P = .046). The prevalences of central nervous system disease, young age (<6 months) at initial operation, and a particular type of antireflux operation were not higher in patients with PPEH. Nine patients with a small PPEH treated by simple observation alone subsequently had resolution of symptoms. Conclusions: Patients who have gagging or slow corrected gastric emptying before an antireflux operation are at higher risk for a postoperative paraesophageal hernia. Patients with a small postoperative paraesophageal hernia can be treated nonoperatively. Crural plication of the esophagus during Nissen fundoplication reduces the occurrence of postoperative paraesophageal hernia, but also may result in significant morbidity.

Management of paraesophageal hernia with a selective approach to antireflux surgery

Background: The role of an antireflux procedure in the management of paraesophageal hernia is controversial. To address this issue, we reviewed our experience with selective use of antireflux procedures in patients with pure paraesophageal hernia (type II; n = 26) and those with a partial sliding component (type III; n = 11). Patients and methods: Surgical repair was performed on diagnosis in all 37 patients. Competency of the lower esophageal sphincter was evaluated on the basis of reflux symptoms, and objectively, with endoscopy in 21 patients and 24-hour esophageal pH studies in 17 patients. Repair included an antireflux procedure in 11 patients, as indicated by reflux disease. Results: Preoperatively, 80% of both type II and type III patients reported obstructive symptoms. Reflux symptoms were present in 27% of patients—19% of type II and 45% of type III patients. Endoscopy revealed esophagitis in 5 cases, and 24-hour pH studies indicated significant reflux in 3 of 17 patients. There were no operative deaths and 1 recurrence. Symptoms improved in 92% of patients after surgery. Medically manageable reflux was identified in 2 patients. Conclusions: Frequent obstructive symptoms and the potential for gastric volvulus indicate elective repair of paraesophageal hernia on diagnosis. Significant gastroesophageal reflux is less common, especially in type II patients, and excellent symptomatic results are obtained with selective application of an antireflux procedure.
