[BACKGROUND] Foix-Alajouanine syndrome (FAS) is a subacute, progressive spinal cord disorder that usually shows abnormalities on spinal cord MRI. Here, the authors report a case of FAS that showed no abnormalities on MRI and was treated. […

[OBJECTIVE] The aim of this study was to introduce the visuo-operative angle (VOA) as a novel neuroanatomical metric for quantifying surgical exposure and visibility in skull base microsurgery. The VOA measures the alignment between surgica…

[INTRODUCTION] Endorectal ultrasound (EUS) is an essential tool for local staging of rectal neoplasia; however, its diagnostic accuracy in distinguishing non-invasive from invasive lesions before transanal endoscopic microsurgery (TEM) rema…

Endodontic microsurgery (EMS) is an important treatment option for endodontic disease when the nonsurgical endodontic treatment fails. However, EMS for maxillary molars often presents a clinical challenge due to the root apex close to the m…

[BACKGROUND]  Surgery is the only salvage treatment for radiotherapy (RT) failures in glottic carcinoma management, and total laryngectomy is performed in the majority of cases, resulting in a substantial decline in the quality of life for …

[BACKGROUND] Per-oral endoscopic myotomy (POEM), Heller myotomy (HM), and pneumatic dilation (PD) offer definitive interventions of achalasia, but comparative analysis of long-term healthcare resource utilization is not well described. This…

Esophageal achalasia is a rare smooth muscle disorder characterized by the absence of peristalsis and impaired relaxation of the lower esophageal sphincter (LES), ultimately leading to obstruction and impaired bolus transit. Pediatric achal…

Naltrexone is a competitive opioid receptor antagonist that is FDA-approved for the treatment of alcohol and opioid use disorders. It is also used as an off-label treatment for a plethora of conditions spanning multiple specialties, includi…

[BACKGROUND] Transanal endoscopic microsurgery (TEM) enables the local excision of rectal neoplasms with minimal invasiveness; however, the long-term oncologic safety for pTis and pT1 lesions, as well as the significance of traditional hist…

[OBJECTIVE] transkeyhole microsurgery for spinal cord tumors requires intraoperative imaging guidance to ensure safe and effective tumor resection. Although optical endoscopy has been widely adopted in clinical settings, it's limited to vis…

[PURPOSE] Achalasia is an uncommon primary esophageal motility disorder characterized by impaired relaxation of the lower esophageal sphincter and esophageal body peristalsis, with a rising prevalence among the elderly due to global populat…

[BACKGROUND] Rectal gastrointestinal stromal tumours (GIST) are uncommon and technically challenging to treat due to the confined pelvic anatomy and proximity to the anal sphincter complex. The oncological goal of surgery is R0 resection, b…

[BACKGROUND] Peritoneal opening (PO) during transanal endoscopic microsurgery (TEM) can cause the pneumorectum to collapse and complicate the procedure. As indications expand to larger, more proximal rectal lesions, understanding the real-w…

[BACKGROUND] Accurate in vivo assessment of rectal lesion invasion remains challenging despite advances in high-definition endoscopy and AI-assisted diagnostics. Some lesions resected endoscopically for presumed superficial pathology are ul…

[BACKGROUND] Minimally invasive surgery, particularly robotic-assisted platforms like the da Vinci systems, has revolutionized colorectal surgery by improving precision and recovery. The novel da Vinci Single-Port (SP) system enables proced…

[BACKGROUND] Minimally invasive approaches to manage early-stage rectal cancer have become popular, offering effective treatment with reduced morbidity. Among them, transanal endoluminal surgery (TES) and endoscopic submucosal dissection (E…

Skull base tumors, which compress the optic chiasm, include meningiomas, craniopharyngiomas, and pituitary macroadenomas and pose a serious neurosurgical problem. The best surgical route, that is, endoscopic endonasal (EEA) versus microsurg…

To evaluate the effectiveness of botulinum toxin injection in improving swallowing function in patients with cricopharyngeal muscle dysfunction (CPMD) following radiotherapy for nasopharyngeal carcinoma (NPC). Cohort study. Outpatients with…
