No-biopsy strategy for coeliac disease is applicable in adult patients: a 'real-world' Scottish experience.

Objective: Emergency interim guidance from the British Society for Gastroenterology (BSG) states that a no-biopsy strategy is possible to diagnose coeliac disease (CD) in adults with elevated transglutaminase IgA antibody (TGA-IgA) levels. We aimed to determine if the suggested TGA-IgA ≥10× ULN is safe and robust in making the diagnosis in adult patients in Scotland. We also aimed to establish if any important co-diagnoses would be missed if no biopsy was performed. Method: All positive coeliac serology results for patients aged >15 years in Scotland in 2016 (Grampian 2019) were accessed. Data were collected on demographics, TGA-IgA titres, D1 sampling, histology and macroscopic findings at upper and lower gastrointestinal (GI) endoscopy. Results: 1037/1429 patients with positive serology proceeded to biopsy, of which 796/1037 (76.8%) were diagnosed as CD. A total of 320/322 (99.37%) patients with TGA-IgA ≥10× ULN were diagnosed as CD giving the cut-off a positive predictive value of 99.38%. No significant co-pathology was found at endoscopy in these patients. Conclusion: Our results show that a no-biopsy strategy using a cut-off of TGA-IgA ≥10× ULN is safe to diagnose CD and that no important pathology would be missed. The European Society for Paediatric Gastroenterology, Hepatology and Nutrition 2020 and BSG COVID-19 interim guidelines are applicable to adult patients in Scotland.

Endoscopically placed venting gastrostomy can be a safe and effective palliative intervention in benign and malignant gastrointestinal obstruction.

Introduction: Chronic gastrointestinal obstruction can precipitate a constellation of symptoms including nausea, vomiting, abdominal distension and pain that negatively impact on health-related quality of life. Decompression via venting gastrostomy can offer symptomatic relief but safety and efficacy data are sparse. This study characterises the diverse venting percutaneous endoscopic gastrostomy (vPEG) cohort at our tertiary referral centre and defines the safety and efficacy of this procedure. Methods: Patients undergoing vPEG between May 2012 and June 2020 were identified from a prospectively maintained database and demographic, procedure-related and mortality data were extracted. Retrospective analysis of case notes provided data on patient symptoms. Last follow-up was May 2021. Results: 27 patients (median age 63, range 18-90 years) underwent vPEG insertion. The majority of vPEGs were for patients with obstruction secondary to locally advanced or metastatic malignancy (n=21/27, 77.8%). Six procedures were performed for benign disease (n=6/27, 22.2%). No patients developed the recognised serious complications of bleeding, perforation or peritonitis from vPEG insertion. Symptoms of nausea (p=0.006), vomiting (p<0.001), abdominal distension (p<0.001) and abdominal pain (p=0.002) were improved following vPEG. Pain beyond the expected postprocedural discomfort was associated with a lower number of days survived postprocedure (p=0.026). Conclusion: vPEG can be a safe and efficacious palliative intervention for benign and malignant chronic gastrointestinal obstruction. Severe postprocedural pain should be promptly investigated to exclude a potential complication. A defined clinical strategy for assessing and managing these patients would facilitate wider recognition of the benefits of vPEG and improve the safety profile in centres with more limited experience.

Gastropexy can be as safe as conventional percutaneous endoscopic gastrostomy (PEG), and biomarkers do not predict short-term or long-term outcomes: a 7-year follow-up audit.

OBJECTIVE: Gastrostomy facilitates artificial enteral feeding but controversy exists around associated morbidity and mortality. This study aimed to report short and long-term outcomes, and identify parameters associated with overall survival. METHODS: A 7-year follow-up audit was undertaken at Aberdeen Royal Infirmary, UK. All patients undergoing endoscopic gastrostomy insertion October 2011-September 2018 were included. Last follow-up was February 2019. Clinical data were prospectively collected. Blood results were retrospectively obtained from electronic records. Statistical analysis was with IBM SPSS V.25. RESULTS: 691 procedures were performed over the 7-year period (520 traditional pull-through percutaneous endoscopic gastrostomy (PEG) and 171 gastropexy procedures to facilitate gastrostomy). Frequency of complications (gastrointestinal bleeding, perforation and peritonitis) was low (each n=1). Overall 7-day and 30-day mortality was 2.2% and 8.4%, respectively. One-year mortality reached 47.6%. There was no difference in survival between PEG and gastropexy procedures (p=0.410). Multivariate analysis reported increased age (p<0.001), increased alkaline phosphatase (p<0.001) and clinical indication (p=0.002) as independently associated with an increased hazard of death. Only age was moderately predictive of mortality (area under the curve 0.74, 95% CI 0.70 to 0.78, p<0.001) in the PEG group. Clinical indication was the only parameter independently associated with mortality in the gastropexy cohort (p=0.003). CONCLUSION: Endoscopic gastrostomy placement can be safe with a low mortality and low risk of serious complications. Blood markers were not associated with short-term or long-term outcomes. Gastropexy to facilitate gastrostomy is a safe alternative to traditional pull-through PEG procedures. Future work should consider quality of life outcomes to assess the benefit of gastrostomy from a patient perspective.
