  • The identification and clinical significance of the curved bacilli remain uncertain. The pathogenicity of the bacteria remains unproven.

  • The principal strength of this report lies in the comprehensive longitudinal documentation of a rare disease entity, including serial high-resolution imaging and endoscopic photography that vividly illustrate its progression and resolution under therapy. The diagnosis was fortified by conclusive microbiological and histopathological evi- dence. However, several limitations must be acknowledged. First, as a single-case report, its generalisability is inherently limited. Second, while the K. pneumoniae isolate was thoroughly characterised pheno- typically, genotypic analysis to definitively identify hypervirulent (hvKP) or multidrug-resistant markers was not performed. Such data would have provided deeper insights into the pathogenicity of the strain. Finally, the patient declined long-term endoscopic follow-up, precluding a definitive anatomical assessment of healing despite sus- tained clinical remission.

    Case Report: A rare case of oesophageal cellulitis caused by Klebsiella pneumoniae: diagnosis, management, and literature review · 2026 · DOI

  • There is a need for a modified approach for closing cervical mTEF in patients with anatomical airway distortion. The current approaches for closing mTEF are often precluded in patients with anatomical airway distortion.

  • There is a lack of awareness about the risk of pneumothorax during endoscopic balloon dilation for oesophageal stricture. There is a need for prompt diagnosis and treatment of pneumothorax in this setting.

    Right pneumothorax during endoscopic balloon dilation for oesophageal stricture following tracheoesophageal fistula surgery: a case report · 2026 · DOI

  • There is a need for long-term surveillance in patients with repaired TEF/EA. There is a lack of understanding about the relationship between congenital foregut anomalies and gastric cancer.

    Case Report: gastric signet-ring-cell adenocarcinoma in a young adult with tracheoesophageal fistula/esophageal atresia and complex gastrointestinal history · 2026 · DOI

  • The study is limited by small sample size. The study is retrospective and descriptive in nature. Larger prospective studies should be conducted to confirm the findings.

    Endoscopic bougienage of cicatricial esophageal strictures in children: Experience of the clinic of the National Center for Maternal and Child Health · 2026 · DOI

  • Conventional EVL may be technically difficult or unsuccessful in cases of severe brosis

  • Further studies are needed to evaluate the performance of the gastroAI model-G in larger populations. Studies are needed to compare the performance of the gastroAI model-G with other AI systems. Research is needed to address the limitations and challenges of using AI systems in clinical practice.

    Usefulness of Artificial Intelligence for Transnasal Esophagogastroduodenoscopy in Clinical Practice · 2026 · DOI

    Usefulness of Artificial Intelligence for Transnasal Esophagogastroduodenoscopy in Clinical Practice · 2026 · DOI

  • Existing traction strategies do not adequately address endoscope instability. There is a need for a simple and dynamic endoscope tip traction technique to facilitate ESD in difficult locations.

  • The current understanding of the effects of balloon Eustachian tuboplasty on the Eustachian tube mucosa is limited. There is a need for further research on the tissue-level effects of the procedure in pediatric populations. The high cost of proprietary balloon systems restricts accessibility to the procedure.

  • Larger multi-centre longitudinal studies are needed to define the longterm trajectory of this phenomenon and its relationship to clinical outcomes. Studies should investigate the development of new treatments for post-EVBL dysphagia, chest pain, and odynophagia. The use of upright manometry, provocative testing, and structured symptom evaluation should be explored in future studies.
