A novel modified endoscopic method for treating patients with refractory gastro-esophageal disease and moderate hiatus hernia

Background and aim: endoscopic anti-reflux mucosectomy (ARMS) is effective for patients with refractory gastroesophageal reflux disease (rGERD) with small hiatus hernia. However, evidence of its applicability in patients with larger hernia sac is lacking. This study aimed to evaluate the efficiency and safety of ARMS for patients with rGERD with moderate hiatus hernia (3-5 cm) and determine the appropriate resection range. Methods: thirty-six patients with rGERD with moderate hiatus hernia were enrolled. They were divided into 2/3 and 3/4 circumferential mucosal resection groups. The patients received modified ARMS. The gastroesophageal reflux disease questionnaire (GERD-Q) and DeMeester scores, endoscopy, 24-h pH monitoring results and lower esophageal sphincter (LES) resting pressure were compared pre- and post-procedure. Therapeutic effects and complications of the two mucosal resection ranges were analyzed. Results: thirty-six patients were enrolled in this study, all of whom had undergone ARMS surgery with at least six-month follow-up. In the 2/3 circumferential mucosal resection group, the GERD-Q score, acid exposure time (AET) and DeMeester score improved significantly compared with those before surgery (p < 0.001). In the 3/4 circumferential mucosal resection group, the GERD-Q score, AET and DeMeeter score worsened after six months (p < 0.001), but there was no difference between the two groups (p > 0.05). In both groups, there was no significant improvement in the ratio of esophagitis grade C/D and LES resting pressure after treatment compared with the baseline values (p > 0.05), and no postoperative bleeding or perforation was observed. The incidence of postoperative esophageal stenosis in the 2/3 circumferential mucosal resection group was lower than that in the 3/4 circumferential mucosal resection group (p = 0.041). (AU)

Clinical feasibility of a new antireflux ablation therapy on gastroesophageal reflux disease (with video).

BACKGROUNDS AND AIMS: New mucosal resective and ablative endoscopic procedures based on gastric cardiac remodeling to prevent reflux have appeared. We aimed to evaluate the feasibility of a new ablative technique named antireflux ablation therapy (ARAT) for control of GERD in patients without hiatal hernia. METHODS: Patients with proton pump inhibitor (PPI)-refractory GERD without hiatal hernia underwent ARAT between January 2016 and October 2019. Gastroesophageal Reflux Disease-Health-Related Quality of Life (GERD-HRQL), upper endoscopy, 24-hour pH monitoring, and PPI use were documented at 3, 6, 12, 24, and 36 months after ARAT. RESULTS: One hundred eight patients were included (61 men [56.5%]; median age, 36.5 years; range, 18-78 years). ARAT was performed on all patients. At the 36-month evaluation, 84 patients had completed the protocol. Median ARAT time was 35.5 minutes (range, 22-51 minutes), and median circumference ablation was 300° (range, 270°-320°). No major adverse events occurred, and 14 of 108 patients (12.9%) presented with stenosis that was responsive to balloon dilation (<5 sessions). At the 3-month evaluation, the acid exposure time (AET), DeMeester score, and GERD-HRQL score had decreased from 18.8% to 2.8% (P = .001), 42.5 to 9.1 (P = .001), and 36.5 to 10 (P = .02), respectively, and these values were maintained up to 36 months. Success (AET <4%) was achieved in 89% and 72.2% at 3 and 36 months, respectively. Related factors at 36 months were as follows: pre-ARAT Hill type II (odds ratio [OR], 3.212; 95% confidence interval [CI], 1.431-5.951; P = .033), post-ARAT 3-month Hill type I (OR, 4.101; 95% CI, 1.812-9.121; P = .042), and AET <4% at 3 months (OR, 5.512; 95% CI, 1.451-7.621; P = .021). CONCLUSIONS: ARAT is a feasible, safe, and effective therapy for early and mid-term treatment of GERD in patients without a sliding hiatal hernia. However, longer follow-up evaluations and randomized comparative studies are needed to clarify its real role. (Clinical trial registration number: NCT03548298.).

[The large hiatal hernia should be acknowledged and respected]. / Det stora hiatusbråcket ­ kräver stor uppmärksamhet och respekt - Vanligt och ofta asymtomatiskt tillstånd som snabbt kan bli potentiellt livshotande.

A hiatal hernia is a partial or total dislocation of the stomach, sometimes together with other intraabdominal organs, through the diaphragmatic esophageal hiatus into the thoracic cavity. The condition is common and often asymptomatic. Old age and obesity are risk factors for developing hiatal hernia. Small hernias might induce gastroesophageal reflux, which usually is satisfactorily treated pharmacologically. Larger hiatal hernias are more often associated with obstructive symptoms including dysphagia, vomiting or discomfort/pain due to compression of adjacent organs/tissues. In severe cases, large hiatal hernias may become incarcerated with ischemia in herniated tissues and need of acute surgical intervention. The risk of complications in association with operation for large hiatal hernias is high, particularly in acute surgery and in elderly patients with co-morbidities.

Liraglutide Effects on Upper Gastrointestinal Investigations: Implications Prior to Bariatric Surgery.

Liraglutide is a glucagon-like peptide type 1 (GLP-1) analogue that is approved for long-term obesity management in North America. While bariatric surgery remains the gold standard for weight loss, an increasing number of patients are on liraglutide in the setting of ongoing workup for bariatric surgery. The presence of gastrointestinal symptoms prior to bariatric surgery may prompt testing for dysmotility, which affects surgical decision making. Here we report six cases where treatment with liraglutide was associated with reversible reduction in gastric and esophageal motility in screening for bariatric surgery. While liraglutide is known to delay gastric emptying, there are minimal reports of how this medication affects gastrointestinal investigations used in this context. The implications of these abnormal screening investigations on candidacy for bariatric surgery are discussed.

The role of impedance monitoring in patients with extraesophageal symptoms.

OBJECTIVES/HYPOTHESIS: Ambulatory esophageal impedance monitoring is commonly employed to assess for nonacid reflux in patients with extraesophageal reflux. We aimed to determine if on therapy impedance data can be predicted from off therapy upper endoscopy, manometry, or pH parameters. STUDY DESIGN: Prospective Cohort Study. METHODS: Patients with extraesophageal reflux symptoms and either partial- or nonresponders to twice-daily PPI underwent impedance monitoring on twice-daily PPI, as well as manometry, upper endoscopy, and 48-hour wireless pH monitoring off acid-suppressive medications for 1 week. Percent time pH < 4 and number of reflux episodes were obtained. Multivariable linear regression was used to determine association between the impedance data on therapy and upper endoscopy, manometry, and pH parameters measured off therapy. RESULTS: Seventy-five patients (77% female, median BMI 29, 38% with hiatal hernia, and 19% with esophagitis) were studied both on and off therapy. Thirty-five percent had abnormal impedance monitoring on therapy and 84% had abnormal pH testing off therapy. There was no significant (P = 0.184) overall correlation between total number of impedance events and the baseline physiologic parameters of hiatal hernia, degree of acid reflux, or manometric findings, with only weak correlation (r = 0.54, P = 0.045) with % time pH < 4 among patients with esophagitis. CONCLUSIONS: In patients with suspected extraesophageal reflux refractory to PPI therapy, impedance measures on therapy cannot be predicted from traditional baseline esophageal physiologic parameters. We recommend caution regarding over-interpretation of impedance data. LEVEL OF EVIDENCE: 2b.

Effect of azithromycin on acid reflux, hiatus hernia and proximal acid pocket in the postprandial period.

BACKGROUND: The risk for acidic reflux is mainly determined by the position of the gastric acid pocket. It was hypothesised that compounds affecting proximal stomach tone might reduce gastro-oesophageal reflux by changing the acid pocket position. OBJECTIVE: To study the effect of azithromycin (Azi) on acid pocket position and acid exposure in patients with gastro-oesophageal reflux disease (GORD). METHODS: Nineteen patients with GORD were included, of whom seven had a large hiatal hernia (≥3 cm) (L-HH) and 12 had a small or no hiatal hernia (S-HH). Patients were randomised to Azi 250 mg/day or placebo during 3 days in a crossover manner. On each study day, reflux episodes were detected using concurrent high-resolution manometry and pH-impedance monitoring after a standardised meal. The acid pocket was visualised using scintigraphy, and its position was determined relative to the diaphragm. RESULTS: Azi reduced the number of acid reflux events (placebo 8.0±2.2 vs Azi 5.6±1.8, p<0.01) and postprandial acid exposure (placebo 10.5±3.8% vs Azi 5.9±2.5%, p<0.05) in all patients without affecting the total number of reflux episodes. Acid reflux occurred mainly when the acid pocket was located above, or at the level of, the diaphragm, rather than below the diaphragm. Treatment with Azi reduced hiatal hernia size and resulted in a more distal position of the acid pocket compared with placebo (below the diaphragm 39% vs 29%, p=0.03). Azi reduced the rate of acid reflux episodes in patients with S-HH (38% to 17%) to a greater extent than in patients with L-HH (69% to 62%, p=0.04). CONCLUSION: Azi reduces acid reflux episodes and oesophageal acid exposure. This effect was associated with a smaller hiatal hernia size and a more distal position of the acid pocket, further indicating the importance of the acid pocket in the pathogenesis of GORD.

Does the presence of a hiatal hernia affect the efficacy of the reflux inhibitor baclofen during add-on therapy?

OBJECTIVES: Reflux inhibitors, like the gamma-aminobutyric acid type B (GABA(B)) receptor agonist, baclofen, block transient lower esophageal sphincter relaxations (TLESRs) and are proposed as an add-on therapy in patients with proton pump inhibitor (PPI)-resistant gastroesophageal reflux. However, as other mechanisms of reflux become more important in the presence of a hiatal hernia (HH), the efficacy of reflux inhibitors to reduce acid and non-acid exposure may be hampered. Therefore, we compared the effect of baclofen in patients with no HH (-HH) and those with a large HH during PPI treatment. METHODS: A total of 27 gastroesophageal reflux disease (GERD) patients on PPI were included; 16 had -HH and 11 had a large (> or =3 cm) HH (+HH). During PPI treatment, the effect of baclofen (3 x 20 mg) on acid and non-acid reflux was evaluated in a randomized, double-blind, placebo-controlled cross-over study. Reflux was measured during 24 h using combined esophageal impedance and pH-metry. RESULTS: The majority of reflux events consisted of both gaseous and liquid reflux with a significant increase in non-acid, mixed reflux episodes in +HH patients compared with those in -HH patients. Acid exposure time was in the normal range in both patient groups during both placebo and baclofen. In this study, baclofen significantly reduced the total number of reflux episodes with 36% in -HH patients and 43% in +HH patients, but did not change the number of acid reflux episodes or total acid exposure time. CONCLUSIONS: This study shows that baclofen is also effective in patients with GERD with +HH, further underscoring the potential of reflux inhibitors as treatment of GERD.

Esophageal acid exposure on proton pump inhibitors in unselected asymptomatic gastroesophageal reflux disease patients.

BACKGROUND AND AIM: Efficacy of proton pump inhibitors (PPIs) on symptoms of gastroesophageal reflux (GER) is supposed to result from normalization of esophageal acid exposure; however, recent data in selected severe patients have challenged this concept. The aim of the study was to investigate 24-hour esophagogastric pH in unselected patients with GER disease in symptomatic remission during PPIs. METHODS: Thirty of the 31 consecutive patients with heartburn enrolled achieved adequate symptom control (4, nocturnal acid breakthrough being shorter (P=0.03) on PPIs b.d. compared with PPIs o.d., 125 minutes (90 to 247) versus 253 minutes (210 to 340). Esophageal acid exposure was 3.3% (1.4% to 7.9%) time at pH<4, 9 patients having increased exposure (ie, >5.5%), 7 of whom on PPIs o.d. Patients with increased acid GER on PPIs had a higher prevalence of esophagitis (67% vs. 22%, P<0.05) and hiatus hernia (78% vs. 39%, P<0.1) at endoscopy off PPIs. CONCLUSIONS: One third of unselected patients with GER disease asymptomatic on PPIs have an increased esophageal acid exposure, especially if their PPI is administered o.d.

Efficacy of a proton pump inhibitor given in the early postoperative period to relieve symptoms of hiatal hernia after open heart surgery.

PURPOSE: To evaluate the efficacy of a proton pump inhibitor, we retrospectively reviewed patients who underwent gastric fiberscopy (GFS) in the early phase after cardiac surgery. METHODS: The subjects were 103 patients who underwent GFS for poor appetite, gastric pain, heartburn, or hematemesis after cardiac surgery. We divided the patients into two groups: group I consisted of 49 patients who received an H2-receptor antagonist (ranitidine hydrochloride 300 mg/day), and group II consisted of 54 patients who received a proton pump inhibitor (PPI; sodium rabeprazole 10 mg/day) as prophylactic treatment. The incidence of upper gastrointestinal (GI) disease was compared in the two groups. RESULTS: Gastric fiberscopy confirmed that 82.5% of the patients had type I hiatal hernia. The incidences of gastric pain and heartburn were significantly higher in group I (12.2% and 83.7%) than in group II (0% and 37.0%). Moreover, gastric bleeding occurred in two patients from group I, one [corrected] of whom died of coagulopathy. The incidences of hemorrhagic gastritis, active ulcer, and reflux esophagitis were significantly higher in group I than in group II, at 22.4%, 22.4%, and 24.5% vs 1.9%, 0%, and 7.4%. CONCLUSIONS: Early postcardiotomy GFS confirmed a high incidence of type I hiatal hernia. However, the proton pump inhibitor given in the early postoperative period proved more effective than the H2-receptor antagonist for relieving GI symptoms and preventing upper GI disorders after cardiac surgery.

Comparison of one or two weeks of lansoprazole, amoxicillin, and clarithromycin in the treatment of Helicobacter pylori.

BACKGROUND: The simplest, most effective, and least expensive Helicobacter pylori therapy remains to be determined. Two weeks of 30 mg lansoprazole bid, 1 gm amoxicillin bid, and 500 mg clarithromycin bid (LAC2) had been shown to be an effective therapy for H. pylori. The aim of this study was to assess whether 1 week of this regimen (LAC1) would have a similar efficacy. MATERIALS AND METHODS: H. pylori-positive patients assessed histologically, by rapid urease test, microbiologically, and by a 13C-urea breath test (13C-UBT) were randomized to receive either LAC1 or LAC2 in a single-center open study. Patients were interviewed 1 to 3 days after completion of therapy to evaluate adverse events and compliance. Efficacy was determined by 13C-UBT at least 4 weeks after antibiotic therapy. RESULTS: Seventy evaluable patients were randomized to receive LAC1 (n = 33) LAC2 (n = 37). Of the 33 LAC1 patients, 30 (91%) were treated successfully (95% confidence interval (CI) = 76-98%), compared with 32 of 37 (86%) in the LAC2 group (95% CI = 71-96%). There was no difference in efficacy between the two groups (Fisher's exact test p = 1.0; 95% CI = -10.3%-19.2%). Patients taking LAC1 experienced significantly fewer severe adverse events than those taking LAC2 (Mann-Whitney U test). One of 64 patients had primary resistance to clarithromycin, and treatment was unsuccessful in this case. Six of the 7 remaining treatment failures developed secondary resistance to clarithromycin. CONCLUSIONS: LAC1 is as effective as LAC2 and is associated with less toxicity. Posttreatment clarithromycin resistance is common in patients who do not experience success with therapy.
