Craniovertebral Junction Transanasal and Transoral Approaches: Reconstruct the Surgical Pathways with Soft or Hard Tissue Endocopic Lines? This Is th…
2017
A variety of pathological conditions may affect the clivus and the craniovertebral junction (CVJ). These include congenital disorders, chronic inflammation, neoplasms, infections, and posttraumatic conditions that could all result in CVJ compression and myelopathy Endoscopic-assisted procedures have been further developed for CVJ decompression and they have now become conventional approaches. The aims of the present study were: (1) to compare “radiological” and “surgical” nasoaxial lines (NAxLs); (2) to introduce an analogous radiological line as a predictor of the superior extension of the transoral approach (palatine inferior dental arch line (PIA); (3) to compare the “radiological” nasop…
The Drainage System of the Paranasal Sinuses: A Review with Possible Implications for Balloon Catheter Dilation
2011
Background Intersinus connections and accessory ostia of the maxillary sinus are well known to rhinologic surgeons but are less known for the remaining paranasal sinuses. Probing and dilatation of the natural ostia of diseased sinuses is being popularized currently by the clinical value of balloon catheter dilation (BCD). Although short-term high success rates with treatment of the dilated ostia/duct have been reported with this technique, the potential impact of fractures of adjacent bony septae on accessory sinus ostia, on mucosally lined surfaces, and on intersinus drainage pathways still has not been considered. The aim of this study was to review the literature on accessory sinus ostia…

Robotic transanal total mesorectal excision: Is the future now?
2021
Total mesorectal excision (TME) is the standard surgical treatment for the curative radical resection of rectal cancers. Minimally invasive TME has been gaining ground favored by the continuous technological advancements. New procedures, such as transanal TME (TaTME), have been introduced to overcome some technical limitations, especially in low rectal tumors, obese patients, and/or narrow pelvis. The earliest TaTME reports showed promising results when compared with the conventional laparoscopic TME. However, recent publications raised concerns regarding the high rates of anastomotic leaks or local recurrences observed in national series. Robotic TaTME (R-TaTME) has been proposed as a nove…
Transnasal endoscopy for direct visual control of esophageal stent placement without fluoroscopy
2012
Placement of self-expanding metal stents (SEMSs) is a well-established treatment for esophageal stenosis and postoperative anastomotic leaks. Conventional endoscopic procedures for SEMS placement require fluoroscopic guidance, but transnasal endoscopy (TNE) with ultraslim endoscopes may allow precise stent release under direct visual control without the need for fluoroscopy. This prospectively collected data investigated the feasibility and safety of TNE-guided SEMS placement without fluoroscopy. Between March 2009 and February 2011, 20 consecutive patients underwent TNE-guided SEMS placement without fluoroscopy. The technical success rate was 100 % and no fluoroscopy was required during th…
Mini-laparoscopy, laparoendoscopic single-site surgery and natural orifice transluminal endoscopic surgery-assisted laparoscopy : novice surgeons’ pe…
2012
Study Type--Therapy (case series) Level of Evidence 4. What's known on the subject? and What does the study add? Over the last few years, minimally invasive urological surgery has evolved towards less invasive, 'scarless' procedures. New surgical concepts, such as those of natural orifice transluminal endoscopic surgery (NOTES) and laparoendoscopic single-site surgery (LESS) have been introduced. Mini-laparoscopy has been rediscovered in an attempt to reduce the invasiveness of standard laparoscopy. This study is the first to compare the perception of surgeons when first facing three different scarless options for performing a porcine nephrectomy and when dealing with the constraints of eac…
Rectal perforation during defecography: extraluminal barium impaction removed by TEM (Transanal Endoscopic Microsurgery).
2016
Defecography is the standard diagnostic technique for the diagnosis of functional disorders of the posterior pelvic compartment. However it has some limits as radiation exposure, low-contrast resolution, some degrees of embarrassment and discomfort for the patients. Furthermore it often fails to directly visualize the changes that affect the pararectal space. Here we present a never described case of rectal perforation after defecography with barium impaction removed by TEM (Transanal Endoscopic Microsurgery).We present a case of a 50 years old woman with extraluminal barium impaction due to perforation occurred during defecography. Both pelvic MR and endoanal ultrasound confirmed the prese…

Murine Microvideo Endoscopy of the Colonic Microcirculation
2007
Natural orifice endoscopy in small animal models has been limited in the past by instrument size and optical performance. In this report, we investigate the feasibility of using a recently developed microvideo endoscopy system to evaluate the colon microcirculation. Using a murine model of acute colitis, microvideo endoscopy was useful in mapping the topography of inflammation as well as identifying relevant structures in the microcirculation. We conclude that natural orifice endoscopy is a useful method for the minimally invasive longitudinal assessment of the colonic mucosal microcirculation.
