[BACKGROUND AND OBJECTIVES] Endoscopic assistance during microsurgical procedures offers several advantages, particularly by enhancing visualization of anatomical structures that are difficult to access using a conventional operating micros…

[PURPOSE] For clinical (c) T1N0M0 rectal adenocarcinoma without adverse pathological features, local excision by transanal endoscopic surgery (TEM) is standard; however, contemporary series still report local recurrence (LR) rates of 15-20%…

[OBJECTIVE] Surgical management of hypothalamic hamartomas (HHs) presents substantial challenges due to their deep-seated location and proximity to critical neurovascular structures. Less invasive techniques, such as endoscopic disconnectio…

Breast cancer is the most common malignant tumor among women worldwide. For patients with a high axillary lymph node burden, axillary lymph node dissection (ALND) remains an essential component of surgical management; however, its associate…

The surgical approach for ossiculoplasty, also known as ossicular chain reconstruction, is chosen based on the extent of concomitant middle ear or mastoid disease, such as chronic otitis media or cholesteatoma. The primary objective of the …

[OBJECTIVE] In this nationwide retrospective study, we sought to evaluate the oncologic and functional outcomes and safety of transoral surgery (TOS) for hypopharyngeal and laryngeal squamous cell carcinomas in Japan and to clarify the appr…

[INTRODUCTION] Photogrammetry holds promise for expanding the domains of microsurgical education. The authors present a technical note and scoping review that explore the use of photogrammetry in neurosurgical anatomy, existing technical gu…

[INTRODUCTION] The advent of the operating microscope revolutionized neurosurgery by introducing stereoscopic visualization and enabling microneurosurgery. Endoscopy, in turn, brought a compact, wide-angle view through minimal access corrid…

[BACKGROUND AND OBJECTIVES] Evaluate the feasibility and functional outcomes of extended transoral resection for anterior commissure (AC) tumors in canines, focusing on laryngeal framework, airway, and vocal function. [METHODS] Twelve dogs…

Gastroparesis is a chronic gastric motility disorder marked by delayed gastric emptying in the absence of mechanical obstruction. For patients with symptoms refractory to medical and dietary therapy, Gastric Peroral Endoscopic Myotomy (G-PO…

Gas bloat syndrome (GBS) is a recognized complication of fundoplication, most commonly associated with the Nissen technique and rarely reported after Toupet fundoplication. We present a 42-year-old man who developed acute GBS with necrotic …

Transaxillary breast augmentation has been long misunderstood, perceived as being more technically difficult, taking longer to perform, and having higher risk of contracture and other complications. This chapter focuses on the nuances of in…

[OBJECTIVE] To analyze the clinical effect of endoscopy-assisted functional rhinoplasty. [METHODS] Endoscopy-assisted functional rhinoplasty was performed in all patients. Deviated nasal septum was corrected, nasal septum cartilage graft w…

[BACKGROUND] Colorectal cancer is the third most common malignancy worldwide with rectal cancer accounting for approximately 30% of all new cases. Surgery is the standard of care in the treatment of localised malignancy and can be performed…

[BACKGROUND AND OBJECTIVES] Endoscopic surgery offers a minimally invasive alternative to microsurgical resection for intraventricular lesions such as colloid cysts, with potential advantages in morbidity and recovery. Although microsurgery…

[PURPOSE] The surgical management of pineal cysts (PC) remains controversial, particularly in non-hydrocephalic patients where radiological and clinical correlations are inconsistent. Most studies rely on cyst size or morphology as surgical…

[BACKGROUND] Polyacrylamide hydrogel, commercially referred to as Amazingel, was prohibited for use in China in 2006 owing to its associated high complication rates. Conventional techniques for its removal are frequently insufficient to ach…

Simultaneous rhytidectomy and laser resurfacing has become a common single-stage facial rejuvenation technique. However, concerns remain, particularly with photothermal injury to undermined tissue. This is the first methodologically robust …

An 80-year-old woman presented with inspiratory stridor after eating. Imaging revealed a decompensated esophagus. Endoscopy showed food retention and a narrowed lower esophageal sphincter. Achalasia, a rare motility disorder, was diagnosed …
