Background: It is questionable whether a symptomatic condition with few serious medical consequences requires proton pump inhibitor (PPI) treatment. If effective, a less-potent treatment may be preferable.
Aim: To compare an H2-blocker in an effervescent formulation with a PPI in on-demand treatment of endoscopy-negative gastro-oesophageal reflux disease (GERD).
Methods: Included were patients with heartburn and/or acid regurgitation for at least 3 months duration, a negative endoscopy and a positive response to 7 days of lansoprazole 60 mg daily. Following pH-metry, the patients were randomized to receive either ranitidine effervescent tablets 75 mg or lansoprazole capsules 15 mg to a maximum of four per day on-demand. The numbers taken were registered monthly for 6 months. If treatment was unsuccessful (lack of efficacy or side effects), patients were registered as failures.
Results: One hundred and three patients were included and 63 were considered for statistical analysis; 32 on lansoprazole and 31 on ranitidine. Seventeen (55%) on ranitidine and four (13%) on lansoprazole failed. The average number of tablets per day was 1.2 in the lansoprazole group and 3.1 in the ranitidine group.
Conclusions: On-demand treatment in patients with endoscopy-negative GERD gives a high success rate with a fairly low dose of PPI. The H2-blocker had significantly less success; nevertheless, almost half were satisfied with the treatment.

The Lyon Score: A Novel Reflux Scoring System Based on the Lyon Consensus 2.0 That Associates With Treatment Outcome From Antireflux Therapy.
Am J Gastroenterol
September 2024
Kenneth C. Griffin Esophageal Center, Northwestern Medicine, Division of Gastroenterology and Hepatology, Feinberg School of Medicine, Northwestern University, Chicago, Illinois, USA.
Article Synopsis
- The study aimed to enhance the diagnosis of gastroesophageal reflux disease (GERD) and predict treatment outcomes using a new scoring system called the Lyon score, based on esophageal test parameters.
- A prediction score was developed from endoscopy and pH-impedance metrics, showing strong performance in a cohort of patients, with an AUC of 0.819 for predicting a 50% reduction in symptoms.
- The Lyon score effectively differentiates reflux types and indicates how likely patients are to respond to antireflux therapy, outperforming existing scores in certain cohorts.
[Construction of a model based on multipoint full-layer puncture biopsy for predicting pathological complete response after neoadjuvant therapy for locally advanced rectal cancer].

To investigate the value of transanal multipoint full-layer puncture biopsy (TMFP) in predicting pathological complete response (pCR) after neoadjuvant radiotherapy and chemotherapy (nCRT) in patients with locally advanced rectal cancer (LARC) and to establish a predictive model for providing clinical guidance regarding the treatment of LARC. In this multicenter, prospective, cohort study, we collected data on 110 LARC patients from four hospitals between April 2020 and March 2023: Beijing Chaoyang Hospital of Capital Medical University (50 patients), Beijing Friendship Hospital of Capital Medical University (41 patients), Qilu Hospital of Shandong University (16 patients), and Zhongnan Hospital of Wuhan University (three patients). The patients had all received TMFP after completing standard nCRT.

Article Synopsis
- A study was conducted to evaluate a short, contrast-free MRI for detecting nasopharyngeal carcinoma (NPC) in patients screened positive for Epstein-Barr virus (EBV) DNA.
- Among 354 patients, MRI identified additional NPC cases that were missed by endoscopy, with high sensitivity and specificity for detecting the cancer.
- The results suggest that MRI can enhance NPC screening programs by finding cases that traditional methods might overlook, improving early detection and reducing the risk of missed diagnoses.
Poliprotect vs Omeprazole in the Relief of Heartburn, Epigastric Pain, and Burning in Patients Without Erosive Esophagitis and Gastroduodenal Lesions: A Randomized, Controlled Trial.
Am J Gastroenterol
November 2023
Dipartimento di Medicina Traslazionale e di Precisione, Sapienza University of Rome, Rome, Italy.
Article Synopsis
- Poliprotect (a mucosal protective agent) was found to be just as effective as omeprazole for treating heartburn and epigastric pain in patients without visible esophageal damage.
- In a 4-week study, 275 participants were treated with either omeprazole or Poliprotect, with Poliprotect showing similar symptom relief and no significant changes in gut microbiota.
- No serious side effects occurred in either treatment group, suggesting Poliprotect is a safe alternative for patients who cannot take proton-pump inhibitors like omeprazole.
Value of transrectal ultrasound-guided biopsy in endoscopy negative biopsy patients with rectal lesions.

Department of Ultrasound, Sichuan Cancer Hospital & Institute, Affiliate Cancer Hospital of University of Electronic Science and Technology of China (UESTC), Chengdu, China.
Objective: To evaluate the value of transrectal ultrasound (TRUS) guided biopsy in endoscopy negative biopsy patients with rectal lesions.
Methods: 150 endoscopy negative biopsy result rectal lesions adopted the transrectal ultrasound-guided biopsy. Based on whether the patients received contrast-enhanced ultrasound examination or not before the biopsies, all enrolled cases were divided into TRUS guided group and contrast-enhanced TRUS (CE-TRUS) guided group, and the safety and diagnostic performances were analyzed retrospectively.
