Paraesophageal Hernia Repair Outcomes Using Minimally Invasive Approaches

Minimally Invasive Abdominal Repair of a Giant Paraesophageal Hiatal Hernia with Occupation of the Right Thorax in a 53-Year-Old Man

Paraesophageal giant hiatal hernia is a rare condition associated with serious complications if not treated surgically. There are no reports of the minimally invasive abdominal repair of a giant hiatal hernia of the stomach almost entirely occupying the right thoracic cavity. The most common clinical presentation includes pathological gastroesophageal reflux, dysphagia, chest pain, or respiratory symptoms such as chronic cough or dyspnoea. Chest computed tomography, upper gastrointestinal endoscopy, and high-resolution oesophageal manometry are used to indicate the best treatment. This article reports the minimally invasive abdominal repair of a case of paraesophageal giant hiatal hernia occupying the right thoracic cavity.

Health-related quality of life after laparoscopic repair of giant paraesophageal hernia: how does recurrence in CT scan compare to clinical success?

Background

Computed tomography (CT) is widely used in the diagnosis of giant paraesophageal hernias (GPEH) but has not been utilised systematically for follow-up. We performed a cross-sectional observational study to assess mid-term outcomes of elective laparoscopic GPEH repair. The primary objective of the study was to evaluate the radiological hernia recurrence rate by CT and to determine its association with current symptoms and quality of life.

Methods

All non-emergent laparoscopic GPEH repairs between 2010 to 2015 were identified from hospital medical records. Each patient was offered non-contrast CT and sent questionnaires for disease-specific symptoms and health-related quality of life.

Results

The inclusion criteria were met by 165 patients (74% female, mean age 67 years). Total recurrence rate was 29.3%. Major recurrent hernia (> 5 cm) was revealed by CT in 4 patients (4.3%). Radiological findings did not correlate with symptom-related quality of life. Perioperative mortality occurred in 1 patient (0.6%). Complications were reported in 27 patients (16.4%).

Conclusions

Successful laparoscopic repair of GPEH requires both expertise and experience. It appears to lead to effective symptom relief with high patient satisfaction. However, small radiological recurrences are common but do not affect postoperative symptom-related patient wellbeing.

The Association of Body Mass Index with Postoperative Outcomes After Elective Paraesophageal Hernia Repair

PURPOSE

To evaluate the association between body mass index (BMI) and postoperative outcomes in elective paraesophageal hernia (PEH) repairs.

METHODS

A retrospective review of patients who underwent elective PEH repair in the ACS NSQIP database (2005-2015) was performed. Patients were stratified into BMI groups (< 18.5, 18.5-24.9, 25.0-29.9, 30.0-34.9, 35-39.9, and ≥ 40.0 kg/m²) according to the World Health Organization classification criteria. A multivariable logistic regression model was developed to characterize the association between BMI class and outcomes, including readmission, reoperation, postoperative complications, and mortality.

RESULTS

The median (IQR) age of the 9641 patients who met inclusion criteria was 64 (55-72) and 72.7% were women. Across each BMI class, age, race, gender, type of procedure, frailty index, smoking, and ASA class varied (p < 0.05). Underweight patients (BMI < 18.5 kg/m²) had an increased risk of mortality (OR = 6.35, p < 0.05). Patients with a BMI 35-39.9 kg/m² (OR = 0.65, p < 0.05) and ≥ 40 kg/m² (OR = 0.36, p < 0.001) were associated with a decreased risk for readmissions.

CONCLUSION

Underweight patients have an increased risk for postoperative mortality after elective PEH repair. Higher BMI was associated with a diminished risk for readmission, but not for mortality, reoperations, or overall complications.

Treatment of giant paraesophageal hernia: pro laparoscopic approach

PURPOSE

Giant paraesophageal hernias (GPEH) are relatively uncommon and account for less than 5% of all primary hiatal hernias. Giant Secondary GPEH can be observed after surgery involving hiatal orifice opening, such as esophagectomy, antireflux surgery, and hiatal hernia repair. Surgical treatment is challenging, and there are still residual controversies regarding the laparoscopic approach, even though a reduced morbidity and mortality, as well as a shorter hospital stay have been demonstrated.

METHODS

A Pubmed electronic search of the literature including articles published between 1992 and 2016 was conducted using the following key words: hiatal hernia, paraesophageal hernias, mesh, laparoscopy, intrathoracic stomach, gastric volvulus, diaphragmatic hernia.

RESULTS

Given the risks of non-operative management, GPEH surgical repair is indicated in symptomatic patients. Technical steps for primary hernia repair include hernia reduction and sac excision, correct repositioning of the gastroesophageal junction, crural repair, and fundoplication. For secondary hernias, the surgical technique varies according to hernia type and components and according to the approach used during the first surgery. There is an ongoing debate regarding the best and safest method to close the hiatal orifice. The laparoscopic approach has demonstrated a lower postoperative morbidity and mortality, and a shorter hospital stay as compared to the open approach. A high recurrence rate has been reported for primary GPEH repair. However, recent studies suggest that recurrence does not reduce symptomatic outcomes.

CONCLUSIONS

The laparoscopic treatment of primary and secondary GPEH is safe and feasible in elective and emergency settings, especially in high-volume centers. The procedure is still challenging. The main steps are well defined. However, there is still room for improvement to lower the recurrence rate.
