Management of Recurrent Paraesophageal Hernia

Cruroplasty as a standalone treatment for recurrent hiatal hernia repair

PURPOSE

Following laparoscopic anti-reflux surgery (LARS), recurrence of hiatal hernia is common. Patients with symptomatic recurrence typically undergo revision of the fundoplication or conversion to magnetic sphincter augmentation (MSA) in addition to cruroplasty. However, patients with an intact fundoplication or MSA may only require repeat cruroplasty to repair their recurrent hiatal hernia. The purpose of this study is to compare outcomes following cruroplasty alone compared to full revision (i.e. redo fundoplication or MSA with cruroplasty) for the management of recurrent hiatal hernias.

METHODS

A retrospective review of patients undergoing surgical revision of a symptomatic recurrent hiatal hernia between February 2009 and October 2022 was performed. Preoperative characteristics, intraoperative details, and postoperative outcomes were compared between patients undergoing cruroplasty alone versus full revision.

RESULTS

A total of 141 patients were included in the analysis. 93 patients underwent full revision, and 48 patients underwent cruroplasty alone. The mean time between initial and revisional surgery was 8 ± 7.7 years. There was no significant difference in operative time or rates of intra-operative or post-operative complication between groups. Patients undergoing cruroplasty alone had a mean Gastroesophageal Reflux Disease Health Related Quality Life (GERD-HRQL) Questionnaire score of 9.6 ± 10.2 compared to a mean score of 8.9 ± 11.2 for full revision patients (p = 0.829). Recurrence rates following revision was 10.4% for cruroplasty alone patients and 11.8% in full revision patients (p > 0.999).

CONCLUSION

In patients with intact fundoplication or MSA, cruroplasty alone results in similar post-operative outcomes compared to full revision for recurrent hiatal hernia.

Elective Laparoscopic Paraesophageal Hernia Repair Leads to an Increase in Life Expectancy Over Watchful Waiting in Asymptomatic Patients: An Updated Markov Analysis

OBJECTIVE

The aim of this study was to perform an updated Markov analysis to determine the optimal management strategy for patients with an asymptomatic paraesophageal hernia (PEH): elective laparoscopic hernia repair (ELHR) versus watchful waiting (WW).

BACKGROUND

Currently, it is recommended that patients with an asymptomatic PEH not undergo repair based on a 20-year-old Markov analysis. The current recommendation might lead to preventable hospitalizations for acute PEH-related complications and compromised survival.

METHODS

A Markov model with updated variables was used to compare life-years (L-Ys) gained with ELHR versus WW in patients with a PEH. One-way sensitivity analyses evaluated the robustness of the analysis to alternative data inputs, while probabilistic sensitivity analysis quantified the level of confidence in the results in relation to the uncertainty across all model inputs.

RESULTS

At age 40 to 90, ELHR led to greater life expectancy than WW, particularly in women. The gain in L-Ys (2.6) was greatest in a 40-year-old woman and diminished with increasing age. Sensitivity analysis showed that alternative values resulted in modest changes in the difference in L-Ys, but ELHR remained the preferred strategy. Probabilistic analysis showed that ELHR was the preferred strategy in 100% of 10,000 simulations for age 65, 98% for age 80, 90% for age 85, and 59% of simulations in 90-year-old women.

CONCLUSIONS

This updated analysis showed that ELHR leads to an increase in L-Ys over WW in healthy patients aged 40 to 90 years with an asymptomatic PEH. In this new paradigm, all patients with a PEH, regardless of symptoms, should be referred for the consideration of elective repair to maximize their life expectancy.

Fundoplication with extensive dissection of the esophagogastric junction: Lessons learned and outcomes from 178 consecutives patients

INTRODUCTION

Antireflux surgery is commonly associated with significant recurrence and complication rates, and several surgical techniques have been proposed to minimize them. The aim of this study is to evaluate the results of a fundoplication with extensive dissection of the esophagogastric junction 1 and 3 years after the procedure.

METHODS

Retrospective observational study including 178 patients with gastroesophageal reflux disease or hiatal hernia who underwent fundoplication with extensive dissection of the esophagogastric junction between 2015 and 2020. Hernia recurrence, symptoms and quality of life at 1 and 3 years after surgery were assessed by barium transit, endoscopy and questionnaires for symptoms and quality of life (GERD-HRQL).

RESULTS

Heartburn rate was 7.5% and 10.7% at 1 and 3 years respectively, regurgitation 3.8% and 6.9% and dysphagia was 3.7% and 7.6%. The presence of hiatal hernia was evident preoperatively in 55.1% and in 7.8% and 9.6% at follow-up and the median GERD-HRQL scale was 27, 2 and 0 respectively. There were no cases of slippage of the fundoplication or symptoms suggestive of vagal injury. No differences were found when comparing the different types of fundoplication in terms of reflux and recurrence or complications.

CONCLUSIONS

Fundoplication with extensive dissection of the esophagogastric junction contributes to correct positioning and better anchorage of the fundoplication, which is associated with low rates of hiatal hernia and reflux recurrence, as well as absence of slippage and lower possibility of vagal injury.

Economic evaluation of robotic and laparoscopic paraesophageal hernia repair

BACKGROUND

Robotic approach in paraesophageal hernia (PEH) repair may improve outcomes over laparoscopic approach, though at additional cost. This study aimed to compare cost-effectiveness of robotic and laparoscopic PEH repair.

METHODS

A decision tree was created analyzing cost-effectiveness of robotic and laparoscopic PEH repair. Costs were obtained from 2021 Medicare data and were accumulated within 60 months after surgery. Effectiveness was measured in quality-adjusted life-years (QALYs). Branch-point probabilities and costs of robotic surgery consumables were obtained from published literature. The primary outcome of interest was incremental cost-effectiveness ratio (ICER). One-way, two-way, and probabilistic sensitivity analyses were performed. A secondary analysis including attributable capital and maintenance costs of robotic surgery was conducted as well.

RESULTS

Laparoscopic repair yielded 3.660 QALYs at $35,843.82. Robotic repair yielded 3.661 QALYs at $36,342.57, with an ICER of $779,488.62/QALY. Robotic repair was favored when rates of open conversion and symptom recurrence were low, or with reduced cost of robotic instruments. A probabilistic sensitivity analysis favored laparoscopic repair in 100% of simulations. When accounting for costs of robotic technology, robotic approach was preferred only in unrealistic clinical scenarios.

CONCLUSIONS

Laparoscopic repair is likely more cost-effective for most institutions, though results were relatively similar. With experienced surgeons who surpass the initial learning curve, robotic surgery may improve outcomes enough to be cost-effective, but only when excluding capital and maintenance fees.

Management of Recurrent Paraesophageal Hernia

Introduction: Recurrent paraesophageal hernias (rPEH) represent a clinical and surgical challenge. Even with a relatively high incidence, most of them are minimally symptomatic, and the need for reoperation is low. For those patients who are candidates for surgery, laparoscopic revision is a feasible and safe technique although there are other treatment options available. Methods: This article provides an overview of the definition, mechanisms of recurrence, epidemiology, clinical presentation, and indications for treatment of rPEH, as well as an overview of the surgical management options and a description of the technical principles of the repair and/or resection. Results: Surgeons should consider multiple factors when deciding the appropriate treatment of patients with rPEH, and all of them require a complete and comprehensive evaluation. The surgical options need to be individualized and include a redo PEH repair and revisional fundoplication, a partial or total gastrectomy with Roux-en-Y reconstruction, or an esophagectomy. There are key steps during the surgical repair that contribute to a successful operation and also auxiliary techniques that can improve postoperative outcomes. After laparoscopic redo most patients have improvement of their symptoms and an acceptable rate of perioperative complications when they are performed by experienced foregut surgeons. In obese patients with rPEH, bariatric surgery can be the best treatment option. Conclusions: Laparoscopic reoperative management should be considered in symptomatic patients who are not controlled with maximal nonoperative therapy, after a thorough work-up and appropriate counseling. In cases with multiple hernia repairs, it is important to consider alternative operations.

When should we use mesh in laparoscopic hiatal hernia repair? A systematic review

The use of mesh in laparoscopic hiatal hernia repair (LHHR) remains controversial. The aim of this systematic review was to determine the usefulness of mesh in patients with large hiatal hernia (HH), obesity, recurrent HH, and complicated HH. We performed a systematic review of the current literature regarding the outcomes of LHHR with mesh reinforcement. All articles between 2000 and 2020 describing LHHR with primary suturing, mesh reinforcement, or those comparing both techniques were included. Symptom improvement, quality of life (QoL) improvement, and recurrence rates were evaluated in patients with large HH, obesity, recurrent HH, and complicated HH. Reported outcomes of the use of mesh in patients with large HH had wide variability and heterogeneity. Morbidly obese patients with HH should undergo a weight-loss procedure. However, the benefits of HH repair with mesh are unclear in these patients. Mesh reinforcement during redo LHHR may be beneficial in terms of QoL improvement and hernia recurrence. There is scarce evidence supporting the use of mesh in patients undergoing LHHR for complicated HH. Current data are heterogeneous and have failed to find significant differences when comparing primary suturing with mesh reinforcement. Further research is needed to determine in which patients undergoing LHHR mesh placement would be beneficial.

[Collis gastroplasty in surgical treatment of hiatal hernia]

OBJECTIVE

To analyze the early and long-term postoperative outcomes after Collis gastroplasty in the treatment of patients with hiatal hernia complicated by gastroesophageal reflux disease and shortening of the esophagus.

MATERIAL AND METHODS

Postoperative outcomes after Collis gastroplasty were analyzed in 22 patients with hiatal hernia and shortening of the esophagus. The control group consisted of 166 patients after simple repair of hiatal hernia without Collis procedure.

RESULTS

In case of Collis gastroplasty, surgery time was 185 (160-250) min. Intraoperative complications were observed in 3 (13.6%) patients, incidence of postoperative complications - 18.2%. There were no lethal outcomes in this group of patients. Mild functional dysphagia was observed in 2 (9.1%) patients. Length of hospital stay was 7.8±2.4 days. Mean follow-up was 34 (6-52) months. There were no anatomical recurrences. A relapse of gastroesophageal reflux was noted in 1 (4.6%) case. GERD-HRQL score was 4.8±2.2 points. Additional Collis gastroplasty did not affect the immediate and long-term results of surgical treatment in comparison with simple cruroraphy and fundoplication.

CONCLUSION

Unreduced shortening of the esophagus may be followed by high incidence of recurrent hiatal hernia and GERD in long-term period. In case of shortening of the esophagus, surgery should include Collis gastroplasty. This effective and safe procedure does not impair treatment outcomes. Indications and optimal technique of Collis gastroplasty require clarification and further research.

Minimally Invasive Paraesophageal Hernia Repair in the Elderly: Is Age Really Just a Number?

Introduction: Paraesophageal hernias readily affect the elderly with a median age of presentation between 65 and 75 years. Laparoscopic paraesophageal hernia repair (PEHR) is a technically challenging operation with potential for dire complications. Advanced age and medical comorbidities may heighten perioperative risk and limit surgical candidacy, potentially refusing patients an opportunity toward symptom resolution. Given the increased prevalence in the elderly and associated surgical risks, we aim to assess age as an independent risk factor for perioperative morbidity and mortality after PEHR. Methods: A retrospective analysis using a prospectively maintained database assessed patients undergoing PEHR from 2007 to 2018. Patients were stratified by age: Group A (age <65 years), Group B (65≤ age <80 years), and Group C (age ≥80 years). Patient demographics, preoperative symptoms, postoperative outcomes, and mortality rate were analyzed. Barium esophagram was performed on symptomatic postsurgical patients. Recurrence was confirmed radiologically. Results: In total, 143 patients underwent laparoscopic (94.4%) or robotic-assisted (5.6%) PEHR. Average age per group was Group A (n = 49) 55.4 years (standard deviation [SD] ±8.91), Group B (n = 76) 71.4 years (SD ±4.40), and Group C (n = 17) 84.1 (years) (SD ±3.37). Group C had significantly higher rates of nonelective surgery (P = .018), preoperative weight loss (P = .014), hypertension (P = .031), ischemic heart disease (P = .001), and cancer (P = .039); preoperative body mass index was significantly lower (P = .048). Charlson comorbidity index differences between groups were significant (2.00 versus 3.61 versus 5.28, P < .001). Median follow-up was 426 days (6-3199). Symptom improvement was seen in 78.3% of patients. Recurrence and reoperation rates were not significantly different between groups. No differences were seen in mortality, length of stay, or postoperative complications between groups. Conclusions: PEHR in elderly patients proved to be safe and effective. Avoidance of emergent intervention may be achieved through a judicious elective approach to this anatomic problem. Symptom resolution and quality-of-life improvement can be safely achieved with surgical repair in this patient population, demonstrating that age is truly just a number for PEHR.

Evolution From the U-shaped to Keyhole-shaped Mesh Configuration in the Repair of Paraesophageal and Recurrent Hiatal Hernia

BACKGROUND

Paraesophageal hernia (PEH) and recurrent hiatal hernia (RHH) are prone to recurrences. One adjunct used to reduce recurrences is mesh reinforcement. The optimal configuration is yet to be determined. We present our evolution from the U-shaped to the keyhole pattern.

METHODS

All patients undergoing PEH/RHH repair with mesh between 2013 and 2019 were reviewed for demographic information, perioperative/intraoperative details, postoperative complications, and recurrences.

RESULTS

Of patients undergoing PEH/RHH repair between 2013 and 2019, 138 were repaired using mesh. Of these, 88 were repaired using the U-shaped configuration and 50 using the keyhole configuration. The U-shaped configuration was used for PEH in 72% and RHH in 28%, while the keyhole configuration was used for PEH in 66% and RHH in 34%. Thirty patients suffered postoperative complications, although there was no difference between the groups. Overall, 28 patients in the U-shaped configuration group (31.8%) had a recurrence of their hiatal hernia identified, compared with 7 patients (14.6%) in the keyhole group (P=0.039). The median time to last follow-up was 21 months (range: 1 to 85) in the U-shaped group and 8 months (range: 1 to 23) in the keyhole group. There was no difference in median time to recurrence, postoperative dysphagia, dilations, or strictures.

CONCLUSIONS

The keyhole pattern mesh was not associated with a higher complication rate compared with the U-shape pattern. Although this study was not a direct comparison between the configurations, it does suggest that the keyhole pattern may lead to fewer recurrences.
