Comparison of patient-centered outcomes after laparoscopic Nissen fundoplication for gastroesophageal reflux disease or paraesophageal hernia

Fundoplication at the time of paraesophageal hernia repair does not decrease the rate of hernia recurrence or postoperative reflux

BACKGROUND

Fundoplication at the time of paraesophageal hernia (PEH) repair is thought to help prevent the development or persistence of postoperative gastroesophageal reflux (GERD) and might also prevent hernia recurrence. However, the published data is not strong enough to definitively recommend this approach. This study was designed to evaluate the effectiveness and complications of a fundoplication at the time of paraesophageal hernia repair.

METHODS

This was a retrospective cohort study of all patients who underwent a paraesophageal hernia repair at a single institution over a 14 year period from 2010 to 2023. Patients were divided into 2 cohorts, those who underwent fundoplication at the time of PEH repair and those who did not. Rates of PEH recurrence, rates of reoperation for a recurrent PEH, postoperative dysphagia rates, and postoperative GERD rates were then compared between the two cohorts.

RESULTS

There were 1,155 patients included in the study. There were 610 (53%) patients who underwent PEH repair with fundoplication and 545 (47%) who did not undergo a fundoplication. 113 (19%) of the patients who underwent fundoplication developed a hernia recurrence compared to 67 (12%) who had a PEH repair alone (p = 0.004). However, each cohort had similar rates of requiring reoperation (p = 0.4). Inclusion of a fundoplication did lead to higher rates of postoperative dysphagia > 30 days postoperatively, 12% vs 7% (p = 0.002), but did not lead to decreased rates of symptomatic GERD postoperatively, 7% with a fundoplication and 7% without (p = 0.93).

CONCLUSION

In this present study, fundoplication at the time of PEH repair did not prevent hernia recurrence, need for reoperation, or decrease postoperative GERD rates but does increase postoperative dysphagia. While there are definite indications for fundoplication at the time of PEH repair (i.e., type 1 hernia), these data do not support the routine use of fundoplication during PEH repair with a normal gastroesophageal flap valve intraoperatively.

[Surgical strategy for hiatal hernias]

The indications for surgical treatment of hiatus hernias differentiate between type I and types II, III and IV hernias. The indications for a type I hernia should include a proven reflux disease but the indications for surgical treatment of types II, III and IV hernias are mandatory due to the symptoms with problems in the passage of food and due to the sometimes very severe possible complications. The primary aims of surgery are the repositioning of the herniated contents and a hiatoplasty, which includes a surgical narrowing of the esophageal hiatus by suture implantation. In addition, depending on the clinical situation other procedures, such as hernia sac removal, mesh implantation, gastropexy and fundoplication can be considered. There are various approaches to the repair, all of which have individual advantages and disadvantages. An adaptation to the specific needs situation of the patient and the expertise of the surgeon is therefore essential.

Resolution and recurrence of anemia following repair of paraesophageal hernias

BACKGROUND

Iron deficiency anemia is a common paraesophageal hernia (PEH) symptom and may improve after repair. When present, anemia has also been proposed to be associated with an increase in length of hospital stay, morbidity, and mortality after PEH repair. This study aimed to determine anemia-related factors in patients with PEH, the rate of anemia resolution after PEH repair, and the risk of anemia recurrence when repair failed.

METHODS

We included patients who received a PEH repair between June 2019 and June 2020 and had 24 months of postoperative follow-up. Demographics and comorbidities were recorded. Anemia was defined as pre-operative hemoglobin values < 12.0 for females and < 13.0 for males, or if patients were receiving iron supplementation. Anemia resolution was determined at 6 months post-op. Length of hospital stay, morbidity, and mortality was recorded. Logistic regression and ANCOVA were used for binary and continuous outcomes respectively.

RESULTS

Of 394 patients who underwent PEH repair during the study period, 101 (25.6%) had anemia before surgery. Patients with pre-operative anemia had larger hernia sizes (6.55 cm ± 2.77 vs. 4.34 cm ± 2.50; p < 0.001). Of 68 patients with available data by 6 months after surgery, anemia resolved in 36 (52.9%). Hernia recurred in 6 patients (16.7%), 4 of whom also had anemia recurrence (66.7%). Preoperative anemia was associated with a higher length of hospital stay (3.31 days ± 0.54 vs 2.33 days ± 0.19 p = 0.046) and an increased risk of post-operative all-cause mortality (OR 2.7 CI 1.08-6.57 p = 0.05). Fundoplication type (p = 0.166), gastropexy, or mesh was not associated with an increased likelihood of resolution (OR 0.855 CI 0.326-2.243; p = 0.05) (OR 0.440 CI 0.150-1.287; p = 0.05).

CONCLUSIONS

Anemia occurs in 1 out of 4 patients with PEH and is more frequent in patients with larger hernias. Anemia is associated with a longer hospital stay and all-cause mortality after surgery. Anemia recurrence coincided with hernia recurrence in roughly two-thirds of patients.

Esophageal Motility Patterns in Paraesophageal Hernia Patients Compared to Sliding Hiatal Hernia: Bigger Is Not Better

BACKGROUND

In patients with paraesophageal hernias (PEH), the course of the esophagus is often altered, which may affect esophageal motility. High-resolution manometry (HRM) is frequently used to evaluate esophageal motor function prior to PEH repair. This study was performed to characterize esophageal motility disorders in patients with PEH as compared to sliding hiatal hernia and to determine how these findings affect operative decision-making.

METHODS

Patients referred for HRM to a single institution from 2015 to 2019 were included in a prospectively maintained database. HRM studies were analyzed for the appearance of any esophageal motility disorder using the Chicago classification. PEH patients had confirmation of their diagnosis at the time of surgery, and the type of fundoplication performed was recorded. They were case-matched based on sex, age, and BMI to patients with sliding hiatal hernia who were referred for HRM in the same period.

RESULTS

There were 306 patients diagnosed with a PEH who underwent repair. When compared to case-matched sliding hiatal hernia patients, PEH patients had higher rates of ineffective esophageal motility (IEM) (p<.001) and lower rates of absent peristalsis (p=.048). Of those with ineffective motility (n=70), 41 (59%) had a partial or no fundoplication performed during PEH repair.

CONCLUSION

PEH patients had higher rates of IEM compared to controls, possibly due to a chronically distorted esophageal lumen. Offering the appropriate operation hinges on understanding the involved anatomy and esophageal function of each individual. HRM is important to obtain preoperatively for optimizing patient and procedure selection in PEH repair.

[Mesh Implantation in Anti-Reflux and Hiatal Hernia Surgery - Contra Statement]

In the surgical treatment of gastroesophageal reflux disease and of hiatal hernias, the high rate of recurrence of hiatal hernias is a central problem. Against this background, various, primarily alloplastic, meshes are used to augment suture closure on the esophageal hiatus. Very different results have been reported in the past and the use of meshes in hiatus reconstruction is controversial. In addition to the frequency of recurrences, reports about complications of mesh augmentation are in the foreground. On the basis of several prospective randomised double-blinded comparative studies and meta-analyses (class Ia and Ib evidence), the current data do not show any advantages of mesh-augmented hiatoplasty for the prevention of recurrence of hiatal hernia. At the same time, there exist reports of more long-term postoperative complications, especially dysphagia, after use of meshes for augmentation of hiatus reconstruction. Therefore, routine use of mesh augmentation for hiatus reconstruction is currently not recommended.

Mind the Gap: Current Treatment Alternatives for GERD Patients Failing Medical Treatment and Not Ready for a Fundoplication

BACKGROUND

Gastroesophageal reflux disease is associated with Barrett esophagus, esophageal adenocarcinoma, and significantly impacts quality of life. Medical management is the first line therapy with surgical fundoplication as an alternative therapy. However, a small portion of patients who fail medical therapy are referred for surgical consultation. This creates a "gap" in therapy for those patients dissatisfied with medical therapy but are not getting referred for surgical consultation. Three procedures have been designed to address these patients. These include radiofrequency ablation (RFA) of the lower esophageal sphincter, transoral incisionless fundoplication (TIF), and magnetic sphincter augmentation.

MATERIALS AND METHODS

A Pubmed literature review was conducted of all publications for RFA, TIF, and MSA. Four most common endpoints for the 3 procedures were compared at different intervals of follow-up. These include percent of patients off proton pump inhibitors (PPIs), GERD-HRQL score, DeMeester score, and percent of time with pH <4. A second query was performed for patients treated with PPI and fundoplications to match the same 4 endpoints as a control.

RESULTS

Variable freedom from PPI was reported at 1 year for RFA with a weighted mean of 62%, TIF with a weighted mean of 61%, MSA with a weighted mean of 85%, and fundoplications with a weighted mean of 84%. All procedures including PPIs improved quality-of-life scores but were not equal. Fundoplication had the best improvement followed by MSA, TIF, RFA, and PPI, respectively. DeMeester scores are variable after all procedures and PPIs. All MSA studies showed normalization of pH, whereas only 4 of 17 RFA studies and 3 of 11 TIF studies reported normalization of pH.

CONCLUSIONS

Our literature review compares 3 rival procedures to treat "gap" patients for gastroesophageal reflux disease with 4 common endpoints. Magnetic sphincter augmentation appears to have the most reproducible and linear outcomes but is the most invasive of the 3 procedures. MSA outcomes most closely mirrors that of fundoplication.

Management of paraesophageal hernia review of clinical studies: timing to surgery, mesh use, fundoplication, gastropexy and other controversies

Despite paraesophageal hernias (PEH) being a common disorder, several aspects of their management remain elusive. Elective surgery in asymptomatic patients, management of acute presentation, and other technical aspects such as utilization of mesh, fundoplication or gastropexy are some of the debated issues. The aim of this study was to review the available evidence in an attempt to clarify current controversial topics. PEH repair in an asymptomatic patient may be reasonable in selected patients to avoid potential morbidity of an emergent operation. In acute presentation, gastric decompression and resuscitation could allow to improve the patient's condition and refer the repair to a more experienced surgical team. When surgical repair is decided, laparoscopy is the optimal approach in most of the cases. Mesh should be used in selected patients such as those with large PEH or redo operations. While a fundoplication is recommended in the majority of patients to prevent postoperative reflux, a gastropexy can be used in selected cases to facilitate postoperative care.

Role of fundoplication in treatment of patients with symptoms of hiatal hernia

Gastroesophageal reflux disease (GERD) is often associated with hiatal hernia (HH). However, the need for fundoplication during hiatal hernia repair (HHR) remains controversial. The objective of this study was to evaluate the effect of HHR with concomitant laparoscopic Nissen fundoplication (HHR-LNF) in HH patients. A total of 122 patients with symptomatic HH were randomized to receive either HHR (n = 61) or HHR-LNF (n = 61). The measures of evaluating outcomes included DeMeester scores (DMS), complications, Reflux Diagnostic Questionnaire and patients' satisfaction 24 months following surgery. Despite comparable values in both groups at randomization, the DMS, total numbers of reflux episodes and percentage of time with pH < 4 were significantly higher in HHR group than in HHR-LNF group (P = 0.017, P = 0.002 and P = 0.019, respectively) at 6 months after surgery. One months postoperatively, complications were higher in the HHR-LNF group than in the HHR group (all P < 0.001), and there was no difference between the two groups at 6 months. By the end of the 2-year follow-up, HHR-LNF group showed a significantly lower reflux syndrome frequency-intensity score and greater percentage of satisfaction compared with HHR group (all P < 0.001). Laparoscopic HHR should be combined with a fundoplication in GERD patients with HH. HHR-LNF is safe and effective, not only improve reflux-related symptom, but also reduce the incidence of complications.

Comparison of Dor and Nissen fundoplication after laparoscopic paraesophageal hernia repair

BACKGROUND

Fundoplication is performed routinely during laparoscopic repairs of a paraesophageal hernia, but the degree of fundoplication remains controversial. The purpose of this study is to assess postoperative dysphagia and reflux after a Dor versus a Nissen fundoplication in patients undergoing laparoscopic repair of giant paraesophageal hernias.

METHODS

We performed a retrospective cohort study of all patients undergoing laparoscopic repair of giant paraesophageal hernias with Nissen or Dor fundoplication between January 2012 and December 2017 at a high-volume center, excluding revisional and emergency cases. Primary outcomes were reflux and dysphagia at 1 and 6 months. Severe dysphagia was defined as intolerance to liquids. Balanced cohorts were created using coarsened exact matching.

RESULTS

A total of 106 patients were included, and 87 were matched (Dor = 48, Nissen = 58). Baseline characteristics were well balanced between matched groups. Mean follow-up duration was 17.7 months (standard deviation 16.4). The incidence of severe dysphagia at 1 month was less in the Dor group (0 of 48 vs 8 of 58, P = .02) with similar reflux symptoms. There was no difference in severe dysphagia and reflux symptoms at 6 months and at the latest visit.

CONCLUSION

Dor fundoplication is associated with less severe, early postoperative dysphagia. Future studies assessing the relative importance of dysphagia and reflux on quality of life should be conducted to tailor the operative technique and optimize patient satisfaction.

Endoluminal Therapy for Gastroesophageal Reflux Disease: In Between the Pill and the Knife?

Gastroesophageal reflux disease (GERD) is a chronic disease characterized by symptoms of heartburn and acid regurgitation. Uncontrolled GERD can significantly impact quality of life, can lead to complications, and increases the risk of esophageal cancer. Over the past few decades, there has been an increasing prevalence of GERD among adults in Western populations. The use of proton pump inhibitors (PPI) in conjunction with lifestyle modifications remains the mainstay therapy. However, the efficacy of this intervention is often hampered by adherence, costs, and the risks of long-term PPI use. Anti-reflux surgery is an option for patients with refractory symptoms or in those in whom medical therapy is contraindicated or not desirable. While conventional surgery has an acceptable safety profile, there has been an increasing interest in alternate treatments that may potentially offer similar results and be associated with a faster recovery. Recent advances in interventional endoluminal techniques have introduced novel incisionless anti-reflux procedures. While the current data are promising, further larger prospective studies are needed in order to assess the long-term efficacy of endoluminal therapies and its place among the treatment options for GERD.

Laparoscopic repair of giant hiatal hernia. A single center experience

INTRODUCTION

Giant hiatal hernia is a rare clinical entity with possibly serious complications, diagnosed mostly among older patients. The laparoscopic repair of such hernias is a therapeutic option, performed mostly in specialized centers by experienced surgeons.

METHODS

From 1997 to 2012 fifty-five patients with giant hiatal hernia (median age of 72) were primarily treated by laparoscopic surgery at the surgical department of the Catholic Clinic Oberhausen. Demographic data, operating times, conversion rate, morbidity and mortality were recorded prospectively. Follow-up was conducted by means of a mailed questionnaire.

RESULTS

Intraoperative complications occurred in 1,8% of the cases (n = 1). In this single case the procedure was converted to an open procedure due to technical difficulties imposed by hepatomegaly. The median operating time was 96 min (range, 30 to 350). Our rate of postoperative complications was 14,5% (n = 8). The median postoperative hospital stay was nine days. 14,5% (n = 8) of our patients underwent a redo-surgery for symptomatic recurrence. The median follow-up was 64 months by means of a self-designed questionnaire. 34,5% (19/55) of the questioned patients responded to our survey. The difference between pre- and postoperative symptom intensity was found to be significant for heartburn (p < 0,001) and retrosternal/epigastric pain (p = 0,028). The difference was not found to be statistically significant for dysphagia (p = 0,8) and bloating (p = 0,3). 85% of the questioned patients stated they would have the operation again, if necessary. 80% reported an improvement of their overall quality of life.

DISCUSSION

The laparoscopic repair of large hiatal hernias is a safe approach with an intraoperative complication rate of 1,8%, low post-operative morbidity (14,5%) and very low mortality (1,8%). There is a high patient satisfaction (85%) and a good postoperative quality of life (80%).

CONCLUSION

The laparoscopic approach for repair of large hiatal hernias is a relatively safe method with significant long-term efficacy in terms of symptom control and quality of life.

A clinical prediction rule for perioperative mortality and major morbidity after laparoscopic giant paraesophageal hernia repair

OBJECTIVE

In the current era, giant paraesophageal hernia repair by experienced minimally invasive surgeons has excellent perioperative outcomes when performed electively. However, nonelective repair is associated with significantly greater morbidity and mortality, even when performed laparoscopically. We hypothesized that clinical prediction tools using pretreatment variables could be developed that would predict patient-specific risk of postoperative morbidity and mortality.

METHODS

We assessed 980 patients who underwent giant paraesophageal hernia repair (1997-2010; 80% elective and 97% laparoscopic). We assessed the association between clinical predictor covariates, including demographics, comorbidity, and urgency of operation, and risk for in-hospital or 30-day mortality and major morbidity. By using forward stepwise logistic regression, clinical prediction models for mortality and major morbidity were developed.

RESULTS

Urgency of operation was a significant predictor of mortality (elective 1.1% [9/778] vs nonelective 8% [16/199]; P < .001) and major morbidity (elective 18% [143/781] vs nonelective 41% [81/199]; P < .001). The most common adverse outcomes were pulmonary complications (n = 199; 20%). A 4-covariate prediction model consisting of age 80 years or more, urgency of operation, and 2 Charlson comorbidity index variables (congestive heart failure and pulmonary disease) provided discriminatory accuracy for postoperative mortality of 88%. A 5-covariate model (sex, age by decade, urgency of operation, congestive heart failure, and pulmonary disease) for major postoperative morbidity was 68% predictive.

CONCLUSIONS

Predictive models using pretreatment patient characteristics can accurately predict mortality and major morbidity after giant paraesophageal hernia repair. After prospective validation, these models could provide patient-specific risk prediction, tailored for individual patient characteristics, and contribute to decision-making regarding surgical intervention.

Modern treatment of paraesophageal hernia: preoperative evaluation and technique for laparoscopic repair

This article reviews the preoperative evaluation of patients with paraesophageal hernia (PEH) and details the principles and components of a laparoscopic PEH repair. Complete hernia sac dissection and excision, adequate esophageal mobilization, reapproximation of the crura, and creation of an antireflux barrier make up the key steps in any repair and are described. Although the preferred operative approach to PEH has undergone significant modification, especially since the introduction of minimally invasive laparoscopic techniques, many controversies still exist. The decision of whether to use mesh to reinforce the crural closure remains an unresolved issue in the surgical literature, and further evolution in this and other areas of PEH surgery is sure to occur in the near future.

Pattern of esophageal eosinophilic infiltration in patients with achalasia and response to Heller myotomy and Dor fundoplication

Eosinophilic esophagitis (EoE) is now recognized as a common cause of dysphagia. Eosinophilic infiltration of the esophagus has also been associated with other conditions, such as gastroesophageal reflux disease (GERD); however, the incidence, pattern, and clinical significance of eosinophilic infiltration in achalasia are poorly documented. We sought to characterize this histological finding in patients undergoing Heller myotomy (HM) for achalasia. Ninety-six patients undergoing laparoscopic HM for primary achalasia between 1999 and 2008 were identified from a prospective database. Serial mid and distal per-endoscopic esophageal biopsies taken from patients before and after surgery were assessed for the presence of elevated intraepithelial eosinophils (EIEs). Slides from patients with reports suggestive of EIE were reviewed independently by two pathologists, and the highest eosinophil count/high-power field (eos/hpf) was recorded. Dysphagia scores (0 = none to 5 = severe dysphagia), GERD health-related quality of life scores (0 = best to 45 = worst), and 24-hour pH results were compared before and 3 months after surgery. We related the highest eos to the symptoms and response to HM. Data are presented as median (range). Paired t-test and Wilcoxon signed-rank test determined significance, *P < 0.05. Of 96 patients with achalasia, 50 had undergone pre-HM biopsies revealing EIE in 17/50 (34%), with a median of 3 eos/hpf (1-21). Two patients were found to have superimposed esophageal candidiasis. One patient met the pathologic criteria for EoE. Twenty-five of 50 (50%) postoperative biopsies demonstrated a median of 5 eos/hpf (1-62) for a total of 28/50 patients (56%) with EIE in either the preoperative or postoperative period. Four patients (8%) met the pathologic criteria for EoE, and two demonstrated persistent esophageal candidiasis. A decrease in eosinophils was found in 6/28 patients (21%) from 3/hpf (1-21) to 0.5/hpf (0-4). Increase in eosinophils was found in 22/28 patients (79%) from 0.5/hpf (0-8) to 5/hpf (1-62). Preoperative and postoperative dysphagia scores were available in 23 patients. Dysphagia scores improved in 22/23 patients. (3 [0-5] to 0 [0-2])*. Preoperative and postoperative GERD scores were available in 21 patients. GERD scores improved in 20/21 patients (10 [3-38] to 2 [2-14])*. Four of 13 patients (30.7%) demonstrated significant reflux in the postoperative period. No difference in clinical response to HM was detected between patients with preoperative EIE compared with patients with no EIE. No correlation between postoperative esophageal pH and eos was observed. A significant number of patients with achalasia demonstrate esophageal eosinophilic infiltration even at numbers demonstrable in patients with EoE (8% 4/50). While the interaction between achalasia and esophageal eosinophilic infiltration needs further investigation, this does not represent a distinct clinical entity. Thus, the presence of esophageal eosinophils in patients presenting with dysphagia should not preclude further work-up for other etiologies, including achalasia.

Efficacy of laparoscopic Nissen fundoplication versus anterior 180º fundoplication in the treatment of gastroesophageal reflux disease

AIM: To compare the efficacy and safety of laparoscopic Nissen fundoplication versus anterior 180^º fundoplication in patients with gastroesophageal reflux disease (GERD).

METHODS: A total of 409 patients with severe GERD who underwent laparoscopic Nissen fundoplication (group N, n = 253) or anterior 180^º fundoplication (group A, n = 156) from June 2004 to May 2008 were included in the study. The pre- and post-operative gastrointestinal quality of life index (GIALI) was assessed in all the patients.

RESULTS: Approximately 76.1% (311/409) of patients had a lower esophageal sphincter (LES) pressure less than 15 mmHg. The mean operation time was significantly longer in group N than in group A (116 min ± 8 min vs 96 min ± 5 min, P < 0.05). The mean duration of postoperative hospitalization was 3.6 d in group N and 3.4 d in group A. Postoperative complications occurred in 3 patients in group N and in 2 patients in group A, and no death occurred. There were 33 patients with postoperative abdominal bloating and 24 patients with postoperative dysphagia in group N, and the corresponding figures in group A were 16 and 14, respectively. The mean duration of follow-up was 46.3 mo ± 6.5 mo (57.2 mo ± 7.3 mo in group N vs 27.6 mo ± 4.2 mo in group A). No statistical differences were noted in life quality score and the results of esophageal manometry and ambulatory 24-h pH monitoring at 2 years of follow-up between the two groups.

CONCLUSION: Both laparoscopic Nissen fundoplication and anterior 180º fundoplication are effective for GERD. Anterior 180º fundoplication is associated with less postoperative adverse effects compared with Nissen fundoplication.

Guidelines for the diagnosis and management of gastroesophageal reflux disease: an evidence-based consensus

Gastroesophageal reflux disease (GERD) is one of the most common disorders in medical practice. A number of guidelines and recommendations for the diagnosis and management of GERD have been published in different countries, but a Brazilian accepted directive by the standards of evidence-based medicine is still lacking. As such, the aim of the Brazilian GERD Consensus Group was to develop guidelines for the diagnosis and management of GERD, strictly using evidence-based medicine methodology that could be clinically used by primary care physicians and specialists and would encompass the needs of physicians, investigators, insurance and regulatory bodies. A total of 30 questions were proposed. Systematic literature reviews, which defined inclusion and/or exclusion criteria, were conducted to identify and grade the available evidence to support each statement. A total of 11,069 papers on GERD were selected, of which 6,474 addressed the diagnosis and 4,595, therapeutics. Regarding diagnosis, 51 met the requirements for the analysis of evidence-based medicine: 19 of them were classified as grade A and 32 as grade B. As for therapeutics, 158 met the evidence-based medicine criteria; 89 were classified as grade A and 69 as grade B. In the topic Diagnosis, answers supported by publications grade A and B were accepted. In the topic Treatment only publications grade A were accepted: answers supported by publications grade B were submitted to the voting by the Consensus Group. The present publication presents the most representative studies that responded to the proposed questions, followed by pertinent comments. Follow examples. In patients with atypical manifestations, the conventional esophageal pH-metry contributes little to the diagnosis of GERD. The sensitivity, however, increases with the use of double-channel pH-metry. In patients with atypical manifestations, the impedance-pHmetry substantially contributes to the diagnosis of GERD. The examination, however, is costly and scarcely available in our country. The evaluation of the histological signs of esophagitis increases the diagnostic probability of GERD; hence, the observation of the dimensions of the intercellular space of the esophageal mucosa increases the probability of diagnostic certainty and also allows the analysis of the therapeutic response. There is no difference in the clinical response to the treatment with PPI in two separate daily doses when compared to a single daily dose. In the long term (>1 year), the eradication of H. pylori in patients with GERD does not decrease the presence of symptoms or the high recurrence rates of the disease, although it decreases the histological signs of gastric inflammation. It seems very likely that there is no association between the eradication of the H. pylori and the manifestations of GERD. The presence of a hiatal hernia requires larger doses of proton-pump inhibitor for the clinical treatment. The presence of permanent migration from the esophagogastric junction and the hernia dimensions (>2 cm) are factors of worse prognosis in GERD. In this case, hiatal hernias associated to GERD, especially the fixed ones and larger than 2 cm, must be considered for surgical treatment. The outcomes of the laparoscopic fundoplication are adequate.

Surgical therapy for gastroesophageal reflux disease: indications, evaluation, and procedures

Gastroesophageal reflux is a very common condition, and surgery remains a reasonable options in select patients. Successful surgical care for GERD depends on proper patient selection, workup and operative technique. This manuscript reviews surgical care for GERD.
