RESUMEN
BACKGROUND: Hiatal hernia (HH) is a common condition. A multidisciplinary expert panel was convened to develop evidence-based recommendations to support clinicians, patients, and others in decisions regarding the treatment of HH. METHODS: Systematic reviews were conducted for four key questions regarding the treatment of HH in adults: surgical treatment of asymptomatic HH versus surveillance; use of mesh versus no mesh; performing a fundoplication versus no fundoplication; and Roux-en-Y gastric bypass (RYGB) versus redo fundoplication for recurrent HH. Evidence-based recommendations were formulated using the Grading of Recommendations, Assessment, Development, and Evaluations methodology by subject experts. When the evidence was insufficient to base recommendations on, expert opinion was utilized instead. Recommendations for future research were also proposed. RESULTS: The panel provided one conditional recommendation and two expert opinions for adults with HH. The panel suggested routinely performing a fundoplication in the repair of HH, though this was based on low certainty evidence. There was insufficient evidence to make evidence-based recommendations regarding surgical repair of asymptomatic HH or conversion to RYGB in recurrent HH, and therefore, only expert opinions were offered. The panel suggested that select asymptomatic patients may be offered surgical repair, with criteria outlined. Similarly, it suggested that conversion to RYGB for management of recurrent HH may be appropriate in certain patients and again described criteria. The evidence for the routine use of mesh in HH repair was equivocal and the panel deferred making a recommendation. CONCLUSIONS: These recommendations should provide guidance regarding surgical decision-making in the treatment of HH and highlight the importance of shared decision-making and consideration of patient values to optimize outcomes. Pursuing the identified research needs will improve the evidence base and may allow for stronger recommendations in future evidence-based guidelines for the treatment of HH.
RESUMEN
BACKGROUND: The surgical management of hiatal hernia remains controversial. We aimed to compare outcomes of mesh versus no mesh and fundoplication versus no fundoplication in symptomatic patients; surgery versus observation in asymptomatic patients; and redo hernia repair versus conversion to Roux-en-Y reconstruction in recurrent hiatal hernia. METHODS: We searched PubMed, Embase, CINAHL, Cochrane Library and the ClinicalTrials.gov databases between 2000 and 2022 for randomized controlled trials (RCTs), observational studies, and case series (asymptomatic and recurrent hernias). Screening was performed by two trained independent reviewers. Pooled analyses were performed on comparative data. Risk of bias was assessed using the Cochrane Risk of Bias tool and Newcastle Ottawa Scale for randomized and non-randomized studies, respectively. RESULTS: We included 45 studies from 5152 retrieved records. Only six RCTs had low risk of bias. Mesh was associated with a lower recurrence risk (RR = 0.50, 95%CI 0.28, 0.88; I2 = 57%) in observational studies but not RCTs (RR = 0.98, 95%CI 0.47, 2.02; I2 = 34%), and higher total early dysphagia based on five observational studies (RR = 1.44, 95%CI 1.10, 1.89; I2 = 40%) but was not statistically significant in RCTs (RR = 3.00, 95%CI 0.64, 14.16). There was no difference in complications, reintervention, heartburn, reflux, or quality of life. There were no appropriate studies comparing surgery to observation in asymptomatic patients. Fundoplication resulted in higher early dysphagia in both observational studies and RCTs ([RR = 2.08, 95%CI 1.16, 3.76] and [RR = 20.58, 95%CI 1.34, 316.69]) but lower reflux in RCTs (RR = 0.31, 95%CI 0.17, 0.56, I2 = 0%). Conversion to Roux-en-Y was associated with a lower reintervention risk after 30 days compared to redo surgery. CONCLUSIONS: The evidence for optimal management of symptomatic and recurrent hiatal hernia remains controversial, underpinned by studies with a high risk of bias. Shared decision making between surgeon and patient is essential for optimal outcomes.

BACKGROUND: Currently very little is known about the impact of anti-reflux surgery on extra-esophageal manifestations of gastroesophageal reflux disease (GERD) when compared with the typical symptoms of reflux. The aim of our study was to evaluate the clinical effect of total (360°) and partial (270°) laparoscopic fundoplication on extraesophageal GERD symptoms. METHODS: One hundred and twenty patients with documented extraesophageal GERD symptoms were randomized to either undergo floppy Nissen (n= 60) or Toupet fundoplication (n= 60). Symptom scores of throat clearing, globus sensation, cough, throat pain, and vocal changes were prospectively evaluated. A reflux symptom index (RSI) questionnaire was used to accurately document the improvement of extraesophageal symptoms. Quality of life was determined according to the laryngopharyngeal reflux-health-related quality of life (LPR-HRQL) questionnaire. RESULTS: No significant differences were identified between the groups regarding demographic data, such as age, gender, or body mass index. The median RSI score before operation and at 24-month follow-up was 22.8 ± 5.3 and 10.4 ± 5.4 respectively in the laparoscopic Nissen fundoplication (LNF) group (p < 0.05) and 21.7 ± 5.0 and 11.6 ± 5 respectively in the laparoscopic Toupet fundoplication (LTF) group (p < 0.05). The median LPR-HRQL score in the LNF group improved from 42.9 ± 13.8 before treatment to 10.7 ± 6.5 at 24 months (p < 0.05). In the LTF group, there was an improvement in the median LPR-HRQL score from 40.4 ± 10.9 prior to treatment to 11.7 ± 5.7 at 24 months (p < 0.05). The median RSI score and LPR-HRQL scores were similar between the groups at follow-up (p > 0.05). CONCLUSIONS: Our report demonstrates that LNF and LTF provide equivalently good results for patients with extraesophageal manifestations of GERD. Quality of life is similar after LNF and LTF.

BACKGROUND: According to recent studies, large hiatal hernias (HH) can be associated with a lower content of type-I and type-III collagen in the phrenoesophageal ligament (POL). We therefore hypothesize that the use of a mesh implant with autologous platelet-rich plasma (PRP) for repair of large HH would have a positive effect on long-term outcome.The purpose of our study was to determine the level of type-I and type-III collagens in the POL of patients with large HH with the aim of improving the technique of HH repair. MATERIALS AND METHODS: During the first phase of the study, the collagen content within the POL was assessed in 18 patients with HH and 14 cadaveric specimens without HH. During the second phase, 54 patients with large HH (defined as 10 to 20 cm2), that required surgery were recruited. Laparoscopic repair involved use of a nonabsorbable self-fixating ProGrip mesh infiltrated with 2 to 4 mL of autologous PRP was used for reinforcement of crural repair. Results were assessed using endoscopy, barium swallow, 24-hour impedance-pH monitoring and a quality of life gastroesophageal reflux disease-health related quality of life questionnaire. RESULTS: The content of collagen within POL in patients with HH was significantly lower than in the cadaveric specimens without HH. Of the 54 patients undergoing HH repair, all procedures were performed laparoscopically and there were no mortalities in this group. At 48 months, only 2 HH recurrences (3.7%) were detected. During this period, the mean gastroesophageal reflux disease-health related quality of life score decreased from 15.7±5.5 to 5.9±0.6 (P<0.05). CONCLUSION: Our study has shown that the collagen content is reduced in patients with large HH; thus, it is advisable to use mesh for HH repair in such patients. Use of mesh infiltrated in PRP is safe and can have positive impact on results of HH repair.

BACKGROUND: Different techniques of wrap fixation in laparoscopic Nissen fundoplication (LNF) have been proposed with of the aim to reduce the complications, but the optimal technique is yet to be determined. The aim of our prospective study was to evaluate several techniques of wrap fixation and determine whether the application of a combined approach to perform wrap fixation reduces the failure rate in short-term and long-term follow-up. MATERIALS AND METHODS: One hundred two patients with sliding or paraesophageal hiatal hernia (type I or type II), who underwent antireflux surgery were randomized into 2 groups. In group I, LNF was supplemented with suturing the wrap to the diaphragmatic crura (35 patients) or to the body of stomach (16 patients). This was dependent on the strength of the crura (defined as weak or strong). The control group (51 patients) underwent LNF without wrap fixation. All patients were assessed using a validated symptom and quality of life (gastroesophageal reflux disease-Health Related Quality of Life) questionnaire, 24-hour impedance-pH monitoring, and barium swallow. RESULTS: At the 48-month follow-up, the overall rate of complications was not significantly different between the 2 groups; however, there was a tendency toward a lower frequency of reoperations in the first group (P=0.059). Fixation of the fundoplication of wrap was noted to lead to significantly lower rates of postoperative dysphagia (P<0.05). These patients (group I) were also found to have significant improvement in gastroesophageal reflux disease-Health Related Quality of Life score (from 19.3±13.2 to 4.3±3.9 vs. from 18.7±11.9 to 9.3±7.7). CONCLUSION: Fixation of the Nissen fundoplication wrap has been shown to have a positive impact on the reduction of postoperative dysphagia and leads to an improvement in disease-specific quality of life.
