Quality of life and predictors of long-term outcome in patients undergoing open Nissen fundoplication for chronic gastroesophageal reflux

Two-Year Outcome after Laparoscopic Fundoplication in Pediatric Patients with Gastroesophageal Reflux Disease

Introduction: Many studies on short-term efficacy of laparoscopic antireflux surgery (LARS) have shown good to excellent results on reflux symptom control and health-related quality of life (HRQoL). Prospective studies on the long-term efficacy, however, are scarce and indicate that the efficacy of symptom control may decline over time. The aim of this study is to assess the 2-year outcome on reflux symptoms and HRQoL after LARS. Materials and Methods: Between 2011 and 2013, 25 children (12 males, median age 6 [2-18] years) with proton pump inhibitor-resistant gastroesophageal reflux disease were included in a prospective longitudinal cohort study. To assess reflux symptoms and HRQoL, patients and/or their caregivers were asked to fill out the validated age-appropriate gastroesophageal reflux symptom questionnaire and Pediatric Quality of Life Inventory™ before, 3 months, 1 year, and 2 years after LARS. Results: Two years after LARS, 29% of patients had moderate to severe reflux symptoms compared with 92% (P < .001) before operation and 12% 3-4 months after operation (P = .219). The significant increase in HRQoL shortly after fundoplication (80.0 compared with 69.5 (P = .004)) is not observed after 2 years (72.0 compared with 69.5, P = .312). Correlation between the impaired HRQoL scores and the recurrence of symptoms could not be verified. Conclusions: Although the efficacy of LARS tends to deteriorate after 2 years, LARS is still effective in controlling reflux symptoms in the majority of patients. The short-term improvement in HRQoL after LARS appears to be transient.

Preoperative factors predicting clinical outcome following laparoscopic fundoplication

BACKGROUND

Antireflux surgery is effective for the treatment of gastroesophageal reflux, but not all patients benefit equally from it. The challenge is to identify the patients who will ultimately benefit from antireflux surgery. The aim of this study was to identify preoperative factors that predict clinical outcome after antireflux surgery, with special interest in the influence of socioeconomic factors.

METHODS

Preoperative clinical and socioeconomic data from 1,650 patients who were to undergo laparoscopic fundoplication were collected prospectively. Clinical outcome measures (persistent heartburn, dysphagia, satisfaction) were assessed at short-term (1 year) and longer-term (≥ 3 years) follow-up.

RESULTS

At early follow-up, male gender (relative risk [RR] 1.091, p < 0.001) and the presence of a hiatus hernia (RR 1.065, p = 0.002) were independently associated with less heartburn. Male gender was also associated with higher overall satisfaction (RR 1.046, p = 0.034). An association was found between postoperative dysphagia and age (RR 0.988, p = 0.007) and the absence of a hiatus hernia (RR 0.767, p = 0.001). At longer-term follow-up, only male gender (RR 1.125, p < 0.001) was an independent prognostic factor for heartburn control. Male gender (RR 0.761, p = 0.001), the presence of a hiatus hernia (RR 0.823, p = 0.014), and cerebrovascular comorbidities (RR 1.306, p = 0.019) were independent prognosticators for dysphagia at longer-term follow-up. A hiatus hernia was the only factor associated with better overall satisfaction. Socioeconomic factors did not influence any clinical outcomes at short- and longer-term follow-up.

CONCLUSION

Male gender and hiatus hernia are associated with a better clinical outcome following laparoscopic fundoplication, whereas socioeconomic status does not influence outcome.

Evaluation of clinical outcome after laparoscopic antireflux surgery in clinical practice: still a controversial issue

Background. Laparoscopic antireflux surgery has shown to be effective in controlling gastroesophageal reflux (GERD). Yet, a universally accepted definition and evaluation for treatment success/failure in GERD is still controversial. The purpose of this paper is to assess if and how the outcome variables used in the different studies could possibly lead to an homogeneous appraisal of the limits and indications of LARS. Methods. We analyzed papers focusing on the efficacy and outcome of LARS and published in English literature over the last 10 years. Results. Symptoms scores and outcome variables reported are dissimilar and not uniform. The most consistent parameter was patient's satisfaction (mean satisfaction rate: 88.9%). Antireflux medications are not a trustworthy outcome index. Endoscopy and esophageal manometry do not appear very helpful. Twenty-four hours pH metry is recommended in patients difficult to manage for recurrent typical symptoms. Conclusions. More uniform symptoms scales and quality of life tools are needed for assessing the clinical outcome after laparoscopic antireflux surgery. In an era of cost containment, objective evaluation tests should be more specifically addressed. Relying on patient's satisfaction may be ambiguous, yet from this study it can be considered a practical and simple tool.

Diagnosis of gastroesophageal reflux disease in infants

Gastroesophageal reflux is commonly encountered in the infant population. Most children will outgrow their reflux but some develop pervasive disease and require medical or surgical treatment. Many tools exist for use in the workup of pediatric gastroesophageal reflux disease; however, the most effective method of diagnosis is not clear. Delineating which patients will benefit from more definitive therapy is a remarkable challenge in this group, often borrowing tools and principles from the adult patient population. Therefore, we reviewed the available literature to critically evaluate the merits and limitations of the current diagnostic modalities available for the evaluation of infantile gastroesophageal reflux.

Development of a quality of life instrument for pediatric gastroesophageal reflux disease: qualitative interviews

OBJECTIVES

Antireflux procedures (ARP) are commonly performed in children and there is no disease-specific quality of life (QOL) instrument for gastroesophageal reflux (GERD) in children. The aim of this study was to identify the relevant domains for developing such an instrument. These domains will be validated in a future study.

PATIENTS AND METHODS

Parents of 19 patients (age 2 months-18 years) clinically diagnosed with GERD were recruited to complete semistructured interviews. Seven patients with adequate verbal skills were also interviewed. Patients were treated medically (13 patients) or with an ARP (6 patients). The interviews were analyzed using grounded theory.

RESULTS

GERD affects QOL through the following domains: symptom severity, feeding quality, sleep quality, hygiene, growth and development, social quality, self-image, coping skills, family QOL, health care usage, and impact of ARP. A greater-than-expected effect on parental QOL and remarkable use of accommodation were identified.

CONCLUSIONS

A pediatric GERD-specific instrument cannot rely on QOL perception alone, but must address broadly the impact of the disease and the effect of coping skills on the child and his or her family in their activities of daily living and interaction with society. We have identified reproducible domains that will serve as the foundation for such an instrument.

Reflux events detected by pH-MII do not determine fundoplication outcome

BACKGROUND

Because of complications and its invasive nature, fundoplication is often a treatment of last resort for children with gastroesophageal reflux. Gastroesophageal reflux testing does not always predict who will benefit from antireflux surgery. Furthermore, there are no studies to determine whether a higher preoperative reflux burden, including acid and nonacid reflux, is associated with an improved postfundoplication outcome. The aim of the study was to determine predictors of fundoplication outcome including acid and nonacid reflux burden.

PATIENTS AND METHODS

We retrospectively reviewed preoperative pH-multichannel intraluminal impedance tracings and medical records of 34 patients who underwent fundoplication. Patients were categorized as improved or not improved, and the demographic and reflux characteristics were compared between groups. Multivariate analysis was performed to determine predictors of outcome.

RESULTS

No single reflux marker, including the number of acid, nonacid, total events, or the percentage of time that reflux was in the esophagus, predicted fundoplication outcome (P > 0.1). Neither a positive symptom index nor a positive symptom sensitivity index predicted postoperative improvement (P > 0.4). Receiver operating characteristic curve analysis failed to reveal an ideal value to maximize sensitivity for either the symptom index or the symptom sensitivity index.

CONCLUSIONS

pH-multichannel intraluminal impedance testing may not be a useful tool in predicting fundoplication outcome.

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.

Who will fail laparoscopic Nissen fundoplication? Preoperative prediction of long-term outcomes

BACKGROUND

A small but significant percentage of patients are considered failures after laparoscopic Nissen fundoplication (LNF). We sought to identify preoperative predictors of failure in a cohort of patients who underwent LNF more than 10 years ago.

METHODS

Of 312 consecutive patients undergoing primary LNF between 1992 and 1995, recent follow-up was obtained from 166 patients at a mean of 11.0 +/- 1.2 years. Eight additional patients who underwent reoperation were lost to follow-up but are included. Failure is broadly defined as any reoperation, lack of satisfaction, or any severe symptoms at follow-up. Potential predictors evaluated included sex, age, body-mass index (BMI), response to acid reducing medications (ARM), psychiatric history, typical versus atypical symptoms, manometry, esophageal pH, and others. Logistic regression was used to assess significance of predictors in univariate analysis.

RESULTS

Of 174 known outcomes, 131 were classified as successful (75.3%), while 43 were failures (24.7%): 26 reoperations, 13 unsatisfied, and 13 with severe symptoms. Response and lack of response to ARM were associated with 77.1% and 56.0% success rates respectively (P = 0.035). Eighty five percent of patients with typical symptoms had a successful outcome, compared to only 41% with atypical symptoms (P < 0.001). Preoperative morbid obesity (BMI > 35 kg/m2) was associated with failure (P = 0.036), while obesity (BMI 30-34.9 kg/m2) was not. A history of psychiatric illness trended toward significance (P = 0.06).

CONCLUSIONS

In a cohort with 11 years follow-up after LNF, factors predictive of a successful outcome include preoperative response to ARM, typical symptoms, and BMI < 35 kg/m2. Patients with atypical symptoms, no response to ARM, or morbid obesity should be informed of their higher risk of failure. Some patients in these groups do have successful outcomes, and further research may clarify which of these patients can benefit from LNF.
