Serum ammonia does not guide management and is overutilised in patients with cirrhosis in hospital settings.

BACKGROUND: Hepatic encephalopathy is a confusional state associated with cirrhosis. Serum ammonia levels are neither sensitive nor specific for the diagnosis. AIMS: We audited the ordering location and hospital unit whilst assessing the impact on management at a major Australian tertiary centre. METHODS: We conducted a single-centre retrospective chart review of the ordering of serum ammonia levels between 1 March 2019 and 29 February 2020 at The Royal Melbourne Hospital, a tertiary-referral centre in Melbourne, Victoria. Demographic, medication and pathology results, including serum ammonia measurements, were collected. The main outcomes assessed were ordering location, sensitivity, specificity and impact on management. RESULTS: A total of 1007 serum ammonia tests were ordered in 425 patients. Nearly all ammonia ordering was by non-gastroenterologists, 24.2% by the intensive care unit, 23.1% by general medicine and 19.5% by the emergency department (ED). Only 21.6% of patients had a history of cirrhosis, with hepatic encephalopathy diagnosed in 13.6%. On subgroup analysis, 217 ammonia tests were performed in 92 patients with cirrhosis. Cirrhotic patients were older (64 vs 59 years, P = 0.012) and had higher median ammonia levels (64.46 vs 59 µmol/L, P < 0.001) compared with non-cirrhotic patients. In cirrhotic patients, the sensitivity and specificity for serum ammonia and diagnosis of hepatic encephalopathy were 75% and 52.3% respectively. CONCLUSION: We affirm the poor utility of serum ammonia levels for guiding management of hepatic encephalopathy within the Australian context. ED and general medical units account for the majority of test ordering within the hospital. Understanding where ordering occurs provides a target for targeted education.

Pathophysiological Mechanisms of Gastro-esophageal Reflux After Sleeve Gastrectomy.

OBJECTIVE: To evaluate the mechanisms associated with reflux events after sleeve gastrectomy (SG). SUMMARY BACKGROUND DATA: Gastro-esophageal reflux (GERD) post-SG is a critical issue due to symptom severity, impact on quality of life, requirement for reoperation, and potential for Barrett esophagus. The pathophysiology is incompletely delineated. METHODS: Post-SG patients, stratified into asymptomatic and symptomatic, underwent protocolized nuclear scintigraphy (n = 83), 24-hour esophageal pH monitoring, and stationary manometry (n = 143) to characterize reflux patterns. Ten patients underwent fasting and postprandial concurrent manometry and pH for detailed analysis of reflux events. RESULTS: Baseline demographics between cohorts were similar: Age 47.2 ± 11.6 versus 44.1 ± 11.3 years ( P = 0.121); females 73.2% versus 90.8% ( P = 0.005); excess weight loss 53.8 ± 28.1% versus 57.4 ± 25.5% ( P = 0.422), follow-up duration 12.3 versus 7.4 months ( P = 0.503). Nuclear scintigraphy delineated bolus-induced deglutitive reflux events (29.6% vs 62.5%, P = 0.005) and postprandial reflux events [4 (IQR2) versus 4 (IQR 3) events, P = 0.356]. Total acid exposure was significantly elevated in the symptomatic population (7.7% vs 3.6%, P < 0.001), especially fasting acid exposure (6.0% vs 1.3%, P < 0.001). pH/manometry analysis demonstrated acute elevations of the gastro-esophageal pressure gradient (>10 mm Hg) underpinned most reflux events. Swallow-induced intragastric hyper-pressur-ization was associated with individual reflux events in most patients (90% in fasting state and 40% postprandial). CONCLUSIONS: We found reflux to be strongly associated with SG and identified 3 unique categories. Bolus-induced deglutitive and postprandial reflux occurred in most patients. Elevated fasting esophageal acid exposure mediated symptoms. Frequent, significant elevation in the gastro-esophageal pressure gradient was the mechanism of reflux and seemed to relate to the noncompliant proximal stomach.

Caustic ingestions over 10 years in Victoria, Australia: high rates in migrants and women.

BACKGROUND: Caustic ingestion is relatively common in developing countries and can result in life-threatening sequelae. There is limited understanding of the epidemiology and incidence in Australia. AIMS: This statewide 10-year audit aims to document the rate of caustic injury in a defined Australian pouplation. METHODS: A retrospective review was conducted over 10 years (2007-2016), including all admissions to hospitals in Victoria. This includes a population of 5.9 million people and 22 hospitals. RESULTS: Three hundred and eighty-four cases of caustic ingestion were admitted to hospital between January 2007 and December 2016. The overall incidence was 7 cases/million/year. This cohort included 217 (56.5%) females, 193 (50.2%) overseas born patients and 196 (51%) people with a history of mental illness. The countries of birth with the highest incidence of caustic ingestion were Ethiopia (11 patients; 227 cases/million/year; relative risk (RR) 31.7; P < 0.0001), Sudan (11 patients; 161 cases/million/year; RR 22.6; P < 0.0001) and India (38 patients; 27 cases/million/year; RR 3.9; P < 0.0001). All had a significantly higher incidence than the Australian-born population of only 6.5 cases/million/year (RR 0.4; P < 0.0001). Of those born in India, Sudan and Ethiopia, rates of females (72%) were considerably higher than males. The overall mortality rate in this cohort was 2.3%. CONCLUSIONS: Caustic ingestion remains a significant cause of morbidity and health expenditure in Victoria, particularly among vulnerable groups such as recent female migrants from areas in Africa and India. The high frequency of events seen in migrant populations highlights the significant need for awareness of risks in these groups for the development of possible prevention strategies that are required.

Outcomes of community-based hepatitis C treatment by general practitioners and nurses in Australia through remote specialist consultation.

BACKGROUND: A unique model of care was adopted in Australia following introduction of universal subsidised direct-acting antiviral (DAA) access in 2016 in order to encourage rapid scale-up of treatment. Community-based medical practitioners and integrated hepatitis nurses initiated DAA treatment with remote hepatitis specialist approval of the planned treatment without physical review. AIMS: To evaluate outcomes of community-based treatment of hepatitis C virus (HCV) through this remote consultation process in the first 12 months of this model of care. METHODS: A retrospective chart review of patients undergoing community-based HCV treatment from general practitioners and integrated hepatitis nurse consultants through the remote consultation model in three state jurisdictions in Australia from 1 March 2016 to 28 February 2017. RESULTS: Sustained virological response at 12 weeks (SVR12) was confirmed in 383 (65.1%) of 588 subjects intended for treatment with a median follow-up time of 12 months (interquartile range 9-14 months). The SVR12 test was not performed in 159 (27.0%) of 588 and 307 (52.2%) of 588 did not have liver biochemistry rechecked following treatment. Subjects who completed follow up exhibited high SVR12 rates (383/392; 97.7%). Nurse-led treatment was associated with higher confirmation of SVR12 (73.7% vs 62.4%; P = 0.01) and liver biochemistry testing post treatment (57.5% vs 45.0%; P = 0.01). CONCLUSIONS: Community-based management of HCV through remote specialist consultation may be an effective model of care. Failure to check SVR12, recheck liver biochemistry and appropriate surveillance in patients with cirrhosis may emerge as significant issues requiring further support, education and refinement of the model to maximise effectiveness of future elimination efforts.

Exploring Symptom Severity, Illness Perceptions, Coping Styles, and Well-Being in Gastroparesis Patients Using the Common Sense Model.

AIMS: This study aimed to examine the relationships between gastroparesis symptom severity, illness perceptions, coping styles, quality of life (QoL), and psychological distress in patients with gastroparesis, guided by the common sense model. METHODS: One hundred and seventy-nine adults with gastroparesis (165 females, 14 males; mean age 41.82 years) completed an online questionnaire. The Gastroparesis Cardinal Symptom Index was used to measure gastroparesis symptom severity, QoL was explored using the PAGI-QOL, illness perceptions were measured using the Brief Illness Perception Questionnaire, the Carver Brief COPE scale assessed coping styles, and psychological distress was investigated using the DASS21. RESULTS: Structural equation modeling resulted in a final model with excellent fit. Gastroparesis symptom severity directly influenced illness perceptions (ß = .52, p < .001) and QoL (ß = .30, p < .001). Illness perceptions directly influenced maladaptive coping (ß = - .64, p < .001), psychological distress (ß = - .32, p < .001), and QoL (ß = .30, p = .01). Maladaptive coping directly influenced psychological distress (ß = .62, p < .001), which in turn had a direct influence on QoL (ß = - .38, p < .001). CONCLUSIONS: The final model showed that the influence of gastroparesis symptom severity on psychological distress was fully mediated by illness perceptions, while the influence on QoL was partially mediated by illness perceptions. The study provides guidance for the development of psychological interventions targeted toward improving mediating psychological factors.

Exploration of the psychosocial issues associated with gastroparesis: a qualitative investigation.

AIMS AND OBJECTIVES: To build on the understanding of how individuals experience gastroparesis, how gastroparesis impacts on their lives and how they adapt to living with gastroparesis. BACKGROUND: Gastroparesis is a neurogastroenterological disorder associated with increased psychological distress and reduced quality of life. Research shows that gastroparesis poses a significant burden across many facets of life; however, less is known about how individuals cope and adapt to living with the condition. DESIGN: The study employed an interpretive phenomenological approach with semistructured interviews and thematic analysis. METHODS: Ten gastroparesis patients were interviewed over the telephone (n = 8), Skype (n = 1) or face-to-face (n = 1). All interviews were audio-recorded and transcribed. RESULTS: Key themes identified: (1) frustration, (2) identity and (3) coping and adaptation. Gastroparesis patients experience significant frustration around their diagnostic journey, being misunderstood and the burden of living with the illness. Patients differed in how they identified with the illness, and this appeared to be associated with adaptation and whether they remained socially engaged. CONCLUSIONS: Gastroparesis is associated with significant frustration and burden; however, some patients adapt to living with the condition more effectively than others. Identity appears to play an important role in this relationship. Support aimed at fostering a health-focused and resilient identity may assist gastroparesis patients in adaptation. RELEVANCE TO CLINICAL PRACTICE: The findings of this study can help nurses and other healthcare professionals better understand the experience of living with gastroparesis and the factors that help patients best adapt to living with the condition. Nurses can help promote resilience in patients by discussing the importance of being health-focused rather than illness-focused. Nurses can also support patients by helping them problem-solve issues that may arise around social eating and remaining socially engaged.

Relations between symptom severity, illness perceptions, visceral sensitivity, coping strategies and well-being in irritable bowel syndrome guided by the common sense model of illness.

Irritable Bowel Syndrome (IBS) is a common condition affecting around 10-20% of the population and associated with poorer psychological well-being and quality of life. The aim of the current study was to explore the efficacy of the Common Sense Model (CSM) using Structural Equation Modelling (SEM) in an IBS cohort. One hundred and thirty-one IBS patients (29 males, 102 females, mean age 38 years) participating in the IBSclinic.org.au pre-intervention assessment were included. Measures included IBS severity (Irritable Bowel Syndrome Severity Scoring System), coping patterns (Carver Brief COPE), visceral sensitivity (Visceral Sensitivity Index), illness perceptions (Brief Illness Perceptions Questionnaire), psychological distress (Depression, Anxiety and Stress Scale), and quality of life (IBS Quality of Life scale; IBS-QoL). Using SEM, a final model with an excellent fit was identified (χ2 (8) = 11.91, p = .16, χ2/N = 1.49, CFI > .98, TLI > .96, SRMR < .05). Consistent with the CSM, Illness perceptions were significantly and directly influenced by IBS severity (ß = .90, p < .001). Illness perceptions in turn directly influenced maladaptive coping (ß = .40, p < .001) and visceral sensitivity (ß = .70, p < .001). Maladaptive coping and visceral sensitivity were significantly associated with psychological distress (ß = .55, p < .001; ß = .22, p < .01) and IBS-QoL (ß = -.28, p < .001; ß = -.62, p < .001). Based on these findings, we argue that to augment the adverse impact of IBS severity on IBS-QoL and psychological distress, psychological interventions will be best to target the mediating psychological processes including illness beliefs, visceral sensitivity and maladaptive coping.

Australian clinical practice guidelines for the diagnosis and management of Barrett's esophagus and early esophageal adenocarcinoma.

Barrett's esophagus (BE), a common condition, is the only known precursor to esophageal adenocarcinoma (EAC). There is uncertainty about the best way to manage BE as most people with BE never develop EAC and most patients diagnosed with EAC have no preceding diagnosis of BE. Moreover, there have been recent advances in knowledge and practice about the management of BE and early EAC. To aid clinical decision making in this rapidly moving field, Cancer Council Australia convened an expert working party to identify pertinent clinical questions. The questions covered a wide range of topics including endoscopic and histological definitions of BE and early EAC; prevalence, incidence, natural history, and risk factors for BE; and methods for managing BE and early EAC. The latter considered modification of lifestyle factors; screening and surveillance strategies; and medical, endoscopic, and surgical interventions. To answer each question, the working party systematically reviewed the literature and developed a set of recommendations through consensus. Evidence underpinning each recommendation was rated according to quality and applicability.

Beyond the heart: Noncardiac chest pain.

BACKGROUND: Noncardiac chest pain (NCCP) is a diagnosis usually made after cardiac investigations have failed to demonstrate a specific diagnosis to explain either a single episode or recurrent episodes of chest pain. OBJECTIVE: The aim of this article is to describe the major causes and management of NCCP, with a focus on gastrointestinal conditions. DISCUSSION: Despite its generally benign prognosis, NCCP is a cause of significant morbidity and can be responsible for a high personal cost and healthcare burden. NCCP is commonly associated with gastrointestinal conditions, including gastro-oesophageal reflux disease and oesophageal spasm. However, the differential diagnosis extends to musculoskeletal, neurological and psychiatric conditions, and the broad range of causes of the syndrome, which are not mutually exclusive, means that clinicians need to remain vigilant for changes in clinical pattern.

Chicago Classification Update (v4.0): Technical review on diagnostic criteria for distal esophageal spasm.

Distal esophageal spasm (DES) is defined as a manometric pattern of at least 20% of premature contractions in a context of normal esophago-gastric junction relaxation in a patient with dysphagia or non-cardiac chest pain. The definition of premature contraction requires the measurement of the distal latency and identification of the contractile deceleration point (CDP). The CDP can be difficult to localize, and alternative methods are proposed. Further, it is important to differentiate contractile activity and intrabolus pressure. Multiple rapid swallows are a useful adjunctive test to perform during high-resolution manometry to search for a lack of inhibition that is encountered in DES. The clinical relevance of the DES-manometric pattern was raised as it can be secondary to treatment with opioids or observed in patients referred for esophageal manometry before antireflux surgery in absence of dysphagia and non-cardiac chest pain. Further idiopathic DES is rare, and one can argue that when encountered, it could be part of type III achalasia spectrum. Medical treatment of DES can be challenging. Recently, endoscopic treatments with botulinum toxin and peroral endoscopic myotomy have been evaluated, with conflicting results while rigorously controlled studies are lacking. Future research is required to determine the role of contractile vigor and lower esophageal sphincter hypercontractility in the occurrence of symptoms in patients with DES. The role of impedance-combined high-resolution manometry also needs to be evaluated.

The effect of laparoscopic adjustable gastric bands on esophageal motility and the gastroesophageal junction: analysis using high-resolution video manometry.

BACKGROUND: Laparoscopic adjustable gastric bands (LAGB) are a safe and effective treatment for obesity. Conflicting data exist concerning their effect on the esophagus, gastroesophageal junction, and mechanism of action. These patients will increasingly require accurate assessment of their esophageal function. METHODS: Twenty LAGB patients underwent high-resolution video manometry with the LAGB empty, 20% under, 20% over, and at their optimal volume. Twenty obese controls were also studied. Effects on esophageal motility, the lower esophageal sphincter (LES), and the gastroesophageal junction were measured. Transit during liquid and semisolid swallows was assessed. RESULTS: The intraluminal pressure at the level of LAGB was a mean of 26.9 (19.8) mm Hg. This pressure varied depending on the volume within the LAGB and was separate to and distal to the lower esophageal sphincter LES. The LES was attenuated compared to controls (10 vs 18 mm Hg; p < 0.01) although relaxed normally. Esophageal motility was well preserved at optimal volume compared to 20% overfilled, with 77% normal swallows vs 51%, p = 0.008. Repetitive esophageal contractions were observed in 40% of swallows at optimal volume compared to 16% in controls, p = 0.024. In comparison to controls, the transit of liquid, 21 vs 8 s (p < 0.001), and semisolids, 50 vs 16 s (p < 0.001), was delayed. CONCLUSIONS: In LAGB patients, the LES is attenuated, although relaxes normally. Esophageal motility is preserved, although disrupted by overfilling the band. In the optimally adjusted LAGB, a delay in transit of liquids and semisolids through the esophagus and band is produced, along with an increase in repeated esophageal contractions.

Value of spatiotemporal representation of manometric data.

BACKGROUND & AIMS: High-resolution manometry with spatiotemporal representation of pressure data is a technique that has developed during the past 10-15 years. We compared spatiotemporal and traditional line plot representation of manometry data in a group of medical students in terms of the ability of the user to come to a rapid and accurate diagnosis and evaluated user preferences for the 2 forms of data display. METHODS: After standardized paper-based and electronic tutorials, 60 medical students classified 30 typical examples of a range of motility disorders in both line plots (10 sensors, including a "virtual sleeve") and spatiotemporal plot format (derived from 16 sensors). Swallows were presented electronically in random order. The accuracy and speed of the assessment were compared between the 2 forms of data presentation, as well as a subjective rating of preference. Results are presented as mean +/- standard error of the mean. RESULTS: Classifications based on data presented in spatiotemporal format were more often correct (89% +/- 1.2% vs 86% +/- 1.3%, P = .002), and correct diagnoses were provided more promptly (25 +/- 2.9 seconds vs 31 +/- 3.2 seconds, P < .001) than in line plot format. Sixty-eight percent of the study population preferred the spatiotemporal presentation. CONCLUSIONS: The analysis of manometry data by manometry-naive individuals is faster and more accurate when data are presented in spatiotemporal than in line plot format. In addition, users preferred the spatiotemporal plots. Spatiotemporal presentation of manometric data is likely to be more easily understood by patients and the "non-expert" physician community.

Nausea and vomiting in adults--a diagnostic approach.

BACKGROUND: Most people experience nausea and vomiting at some stage, but when these symptoms recur frequently they can significantly reduce quality of life. In most cases, a thorough history, examination and simple investigations can yield a diagnosis. Chronic nausea is a more challenging problem with its many potential causes and with a significant number of patients remaining undiagnosed despite extensive investigation. OBJECTIVE: This article discusses the assessment and management of acute and chronic nausea and vomiting in adults. DISCUSSION: Gastrointestinal infections and food poisoning are the most common causes of acute nausea and vomiting. Medication side effects and pregnancy should always be suspected. Hospitalisation may be required for severe metabolic abnormalities, dehydration or surgical causes. There are many potential causes of chronic nausea and vomiting and a comprehensive history and examination is required. Symptoms are poor predictors of functional versus pathological illness. Type and extent of investigation must be tailored to the individual patient.

Psychological controversies in gastroparesis: A systematic review.

AIM: To systematically review literature addressing three key psychologically-oriented controversies associated with gastroparesis. METHODS: A comprehensive search of PubMed, CINAHL, and PsycINFO databases was performed to identify literature addressing the relationship between gastroparesis and psychological factors. Two researchers independently screened all references. Inclusion criteria were: an adult sample of gastroparesis patients, a quantitative methodology, and at least one of the following: (1) evaluation of the prevalence of psychopathology; (2) an outcome measure of anxiety, depression, or quality of life; and (3) evidence of a psychological intervention. Case studies, review articles, and publications in languages other than English were excluded from the current review. RESULTS: Prevalence of psychopathology was evaluated by three studies (n = 378), which found that combined anxiety/depression was present in 24% of the gastroparesis cohort, severe anxiety in 12.4%, depression in 21.8%-23%, and somatization in 50%. Level of anxiety and depression was included as an outcome measure in six studies (n = 1408), and while limited research made it difficult to determine the level of anxiety and depression in the cohort, a clear positive relationship with gastroparesis symptom severity was evident. Quality of life was included as an outcome measure in 11 studies (n = 2076), with gastroparesis patients reporting lower quality of life than population norms, and a negative relationship between quality of life and symptom severity. One study assessed the use of a psychological intervention for gastroparesis patients (n = 120) and found that depression and gastric function were improved in patients who received psychological intervention, however the study had considerable methodological limitations. CONCLUSION: Gastroparesis is associated with significant psychological distress and poor quality of life. Recommendations for future studies and the development of psychological interventions are provided.

The Physiology and Pathophysiology of Gastroesophageal Reflux in Patients with Laparoscopic Adjustable Gastric Band.

INTRODUCTION: The effect of the laparoscopic adjustable gastric band (LAGB) on esophageal acid exposure and reflux is poorly understood. Optimal technique and normative values for acid exposure have not been established in this group. METHODS: High-resolution manometry (HRM) and 24-h ambulatory esophageal pH monitoring were performed in three groups: asymptomatic LAGB, symptomatic LAGB, and pre-operative reflux patients. This technique utilized intraluminal pressure signatures during HRM to guide accurate pH sensor placement. RESULTS: The LAGB groups were well matched: age 48 vs 51 years (p = 0.249), weight loss 27.3 vs 26.7 kg (p = 0.911). The symptomatic group had a larger gastric pouch (5.2 vs 3.3 cm, p = 0.012), with higher esophageal acid exposure (10.8 vs 0.9%, p < 0.001). Two acidification patterns were observed: irritant and volume acidification, associated with substantial supine acidification. Symptomatic LAGB had altered esophageal motility, with poorer lower esophageal sphincter basal tone (8.0 vs 17.7 mmHg, p = 0.022) and impaired contractility of the lower esophageal segment (90 vs 40%, p = 0.009). Compared to pre-operative reflux patients, symptomatic LAGB patients demonstrated higher total and supine esophageal acid exposure (10.8 vs 7.0%, p = 0.010; 14.9 vs 5.1%, p < 0.001), less symptoms (2 vs 6, p = 0.001) and lower symptom index (0.7 vs 0.9, p = 0.010). CONCLUSIONS: Ambulatory pH monitoring is an effective technique if the pH sensor is positioned appropriately using HRM. The correctly positioned LAGB appears associated with low esophageal acidification. In contrast, patients with symptoms or pouch dilatation can have markedly elevated esophageal acidification, particularly when supine. This is a different pattern compared to pre-operative patients and importantly can be disproportionate to symptoms.

Changes in Outcomes, Satiety and Adverse Upper Gastrointestinal Symptoms Following Laparoscopic Adjustable Gastric Banding.

BACKGROUND: Patient-reported outcomes and perceptions are critical to the overall efficacy and acceptability of a surgical procedure. Outcomes, such as patient satisfaction and perceived success of the surgery and adverse symptoms, have not been described in detail following bariatric surgery. The associations and predictors of patient satisfaction have not been defined. This study aimed to examine long-term outcomes and perceptions after laparoscopic adjustable gastric banding (LAGB). METHODS: We conducted a prospective study of outcomes, satiety and adverse upper gastrointestinal symptoms, as well as quality of life and subjective patient satisfaction in LAGB patients. Data were collected at 3 years (T1) and 8 years post-operatively (T2). RESULTS: One-hundred and sixty patients completed follow-up at T1 and T2. The average age was 44.0 ± 11.2 years. At T2, the total body weight loss was 17.8 ± 11.9 %. Satisfaction decreased significantly between time points (8.6 ± 1.8 vs 7.2 ± 2.9, p < 0.01), and quality of life reduced slightly across all domains. Hunger scores remained low (3.8 ± 1.8 vs 3.9 ± 1.8, p = 0.61). The dysphagia score did not change significantly (p = 0.54). There was minimal change in frequency of regurgitation, although there was significant increase in patient assessment of how bothered they were by regurgitation. Multivariate analysis identified increased awareness of regurgitation as a principal driver of reduced satisfaction. CONCLUSIONS: Weight loss, satiety and adverse symptoms demonstrated only slight changes between 3 and 8 years post-operatively. Despite this, overall satisfaction and perception of success of the procedure reduced markedly. This appeared mediated by reduced tolerance of adverse symptoms. These data inform follow-up practises aimed at optimizing outcomes.

Concurrent Large Para-oesophageal Hiatal Hernia Repair and Laparoscopic Adjustable Gastric Banding: Results from 5-year Follow Up.

OBJECTIVE: The objective of the study is to identify the efficacy and safety of combining laparoscopic adjustable gastric banding with repair of large para-oesophageal hernias. BACKGROUND: Para-oesophageal hernias are more common in the obese with higher recurrence rates following repair. The effect and safety of combining para-oesophageal hernia repair with laparoscopic adjustable gastric banding is unknown. METHODS: One-hundred fourteen consecutive patients undergoing primary laparoscopic adjustable gastric banding with concurrent repair of a large para-oesophageal hernia were prospectively identified and matched to a control group undergoing primary laparoscopic adjustable gastric banding only. Weight loss and complication data were retrieved from a prospectively maintained database, and a standardised bariatric outcome questionnaire was used to assess post-operative symptoms, satisfaction with surgery and satiety scores. RESULTS: At a mean follow up of 4.9 ± 2.1 years, total weight loss was 16.4 ± 9.9% in the hernia repair group and 17.6 ± 12.6% in the control group (p = 0.949), with 17 vs. 11% loss to follow up rates (p = 0.246). No statistically significant difference in revisional surgery rate and symptomatic recurrence of hiatal hernia was documented in four patients in the hernia repair group (3.5%). No statistically significant difference in mean reflux (9.9 vs. 10.3, p = 0.821), dysphagia (20.7 vs. 20.1, p = 0.630) or satiety scores was identified. CONCLUSIONS: Concurrent repair of large para-oesophageal hiatal hernia and laparoscopic adjustable gastric banding placement is safe and effective both in terms of symptom control and weight loss over the intermediate term. In obese patients with large hiatal hernias, consideration should be given to combining repair of the hernia with a bariatric procedure.
