“…The length of AA , CC , AA 0 and CC 0 are represented by l AA , l CC , l AA 0 , l CC 0 respectively. The relation between ϕ, α, and l CC can be derived as below (11), as shown at the bottom of this page.…”

“…Hence, if we combine equations (8), (11), and (12), we will have three equations with as many as unknowns(α, θ, and ϕ). By transforming the equations (11) and (12), the unknowns θ and ϕ can be represented by the expressions of α. If we substitute the expressions into equation 8, a nonlinear equation of α can be obtained.…”

“…Therefore, discomfort or damage is more likely to occur when instruments pass through gastroesophageal junction. For example, in peroral endoscopic esophageal myotomy, mucosal perforation occurring around the esophagogastric junction is very common and considered as a serious complication [11]. In this paper, we focus on the method to reduce the forces exerted on the esophagus in transoral NOTES.…”

In natural orifice transluminal endoscopic surgery, the insertion of surgical instruments can cause patient discomfort, even bleeding and perforation. This paper proposes a design of an overtube which can vary its radial dimension. It can be inserted through the natural orifice in a small diameter configuration and then enlarge its size and form a hollow and rigid channel to allow passing instruments, while to reduce the friction between the instruments and the surrounding tissue. A Bricard linkage is used as the basic unit of the overtube and a mechanism is designed to drive multiple Bricard units to fold or unfold. Optimization of the design parameters has been studied and comparison experiments have been completed to verify the feasibility of the design on reducing the shear forces and normal forces exerted during surgical instrument insertion. The ex vivo experiment is also completed to prove the protection of the overtube on the esophagus during the insertion. INDEX TERMS Deployable structure, forces exerted on the esophagus, mechanical design, protective device, transesophageal surgery.

“…5 Postoperative management of POEM involves the assessment of esophageal leaks, perforations or submucosal bleeding before resuming oral intake given the potential severity of adverse events (AE) such as mediastinitis or peritonitis. 6 Second-look endoscopy (SE) on postoperative day (POD) 1 is thought to be important in order to evaluate the integrity of the entry site and the development of AE such as mucosal injury and hemorrhage. 7,8 Indeed, the current clinical practice guideline for POEM recommends performing SE after the operation.…”

Objectives Per‐oral endoscopic myotomy (POEM) is a safe and effective treatment for achalasia and esophageal motility disorders. The role of second‐look endoscopy (SE) on postoperative day 1 has not been examined. This study aimed to evaluate the findings and need of SE after POEM. Methods This is a single‐center, retrospective study. All consecutive patients who underwent POEM and SE on postoperative day 1 between December 2017 and September 2019 were included. The primary endpoint was the rate of newly‐detected adverse events (nAE) during SE that required endoscopic intervention or deviation from the normal postoperative course. Multivariate logistic regression was used to identify predictors of nAE. Results Four‐hundred‐ninety‐seven patients (mean age, 50.3 years; female, 49.9%) were included. SE identified abnormal findings in a total of 71 patients (14.3%). nAE which required endoscopic intervention or deviation from the normal postoperative course were identified in 12 patients (2.4%): eight (1.6%) entry site dehiscence; two (0.4%) submucosal hemorrhage or hematoma; and two (0.4%) dehiscence of an intraoperative perforation site after endoclip closure. Other findings such as mucosal thermal damage without perforation and small submucosal hematoma were found in 54 patients (10.9%) and five patients (1.0%), respectively. Multivariate analysis showed that longer operation time and intraoperative adverse events (AE) were associated with clinically significant nAE during SE. Conclusions Second‐look endoscopy can detect and treat nAE that may lead to severe AE. Thus, SE should be highly considered before starting oral ingestion in all cases, and especially in those who present an intraoperative AE and longer operation time.

“…Among the various complications associated with endoscopic procedures, a minority of them are still related to the limitations of the instruments that are used in achieving the goal of minimally invasive treatment [1,2]. This is especially true for novel indications, such as EUSguided gastroenterostomy [3], natural orifice transluminal endoscopic surgery (NOTES) [4], or submucosal endoscopy [5]. Similarly, endoscopic necrosectomy is cumbersome, being performed with tools borrowed from the armamentarium of other procedures, which may therefore have designs that are not suitable for the performance of all of the different steps in endoscopic necrosectomy.…”
