INTRODUCTION: Endoscopic discectomy and fusions have been gaining popularity in the recent past and are noted to be safe for its application in elderly population. It involves ultra-small incision for discectomy followed by placement of percutaneous screws in awake patients. Treatment of advanced spinal pathology using endoscope-assisted techniques are challenging. Although not common with endoscopic approach, post-operative infection can be problematic as there are no established guidelines on its management...

PURPOSE: The widely used external approach (Weber-Fergusson incision) for the removal of maxillary ethmoid tumors leaves stigmatizing scars and deformities on the patient's face. As an alternative technique, the scarless facial degloving approach was first described in the 1970s; since then, several modifications have been developed. PATIENTS AND METHODS: The authors have been using a modified facial degloving technique for 7 years to remove maxillary ethmoid tumors...

BACKGROUND AND AIMS: Small bowel and colorectal muscle biopsies require a surgical approach. Advancing our understanding of the pathophysiology of motility disorders, such as functional bowel disorders, intestinal pseudo-obstruction and slow transit constipation, is hindered by our inability to non-invasively obtain muscularis propria (MP) for evaluation of multiple cell types, including myenteric neurons. The aims of this study were to determine (1) technical feasibility, reproducibility and safety of performing duodenal endoscopic muscle biopsy (dEMB) and rectal endoscopic muscle biopsy (rEMB) using a clip-assist technique; and (2) presence of myenteric neurons in tissue samples...

BACKGROUND AND AIMS: Endoscopic full-thickness resection (EFTR) is still challenging and a reliable technique is desirable. The aim of this study was to evaluate the feasibility of controlled EFTR using a pseudopolyp made from suture loop needle-T-tag (SLNT) tissue anchors in ex vivo porcine stomachs. METHODS: Five pig stomachs were used. Two concentric circumferential border mucosal incisions were made to facilitate isolating a target lesion for full-thickness excision and pseudopolyp formation...

BACKGROUND: Conventional endoscopy and endoscopic ultrasonography (EUS) are used to estimate the invasion depth of early-stage gastric cancers (EGCs), but estimates made by either technique are often inaccurate. We developed a model to determine the invasion depth of EGCs using conventional endoscopy and EUS findings, with pathology results as the reference. METHODS: We performed a retrospective study of 195 patients (205 lesions) diagnosed with gastric cancers who underwent endoscopy and EUS followed by resection...

BACKGROUND: Peroral cholangioscopic lithotripsy is a useful procedure in patients with a normal gastrointestinal anatomy who have difficult-to-treat stones. We evaluated the usefulness of peroral direct cholangioscopy (PDCS) using single-balloon enteroscope (SBE) in patients with difficult-to-treat stones who had undergone Roux-en-Y reconstruction. METHODS: Among 118 patients (169 sessions) who underwent SBE-assisted endoscopic retrograde cholangiopancreatography to treat biliary stones after Roux-en-Y reconstruction, patients in whom it was difficult to remove biliary stones via a transpapillary or transanastomotic approach and difficult to switch to ultra-slim endoscope, were retrospectively enrolled...

BACKGROUND: In open surgery, extraperitoneal sublay mesh implantation is generally preferred to intraperitoneal placement, following the same principles as in "giant prosthetic reinforcement of the visceral sac" described for inguinal hernia repair [1, 2]. Miserez and Penninckx in 2002 described an endoscopic totally preperitoneal ventral hernia repair in a small cohort of 15 cases [3]. Unfortunately, this technique has not spread, probably because of the technical difficulties that require, but not for effectiveness...

Background and study aim Endoscopic ultrasound-guided rendezvous (EUS-RV) is increasingly reported as a treatment option after failed endoscopic retrograde cholangiopancreatography. We developed a novel "hitch-and-ride" catheter for biliary cannulation to reduce the risk of guidewire loss during EUS-RV. Patients and methods We retrospectively evaluated safety and technical success of EUS-RV between June 2011 and May 2016. Biliary cannulation during EUS-RV using three methods - over-the-wire, along-the-wire, and hitch-and-ride - were compared...

A 43-year-old man with complaints of increased difficulty of swallowing and weight loss underwent videofluorographic examination of swallowing, which revealed severely reduced cricopharyngeal opening. Endoscopic cricopharyngeal myotomy was performed using a modified technique (mECPM). A benign fibrotic stricture of the upper esophageal sphincter (UES) was identified under visualization of a distending operating laryngoscope. A vertical midline incision in the strictured mucosa and submucosal resection of the cricopharyngeal muscle were performed using a CO2 laser...

BACKGROUND: Cold polypectomy has been widely accepted for removal of small colorectal polyps. However, no large-scale prospective study exists as for its safety in Japan. We investigated this issue in this single-center, prospective cohort study in a total of 1198 colorectal polyps resected with cold polypectomy. PATIENTS AND METHODS: Four hundred and seventy-four patients who underwent cold polypectomy for colorectal neoplastic lesions less than 10-mm diameter between September 2014 and October 2016 were enrolled...

C A Gutschow, P Bauerfeind
Over the last 20-30 years, treatment of pharyngoesophageal diverticula was subject to a number of fundamental changes. Considering the classical open transcervical approaches, the necessity for myotomy of the upper esophageal sphincter with the goal of interrupting the pathogenesis of the disease has become a standard component of the operation. On the other hand, with the growing popularity of rigid and flexible endoscopic techniques, pharyngoesophageal diverticula are increasingly being treated by gastroenterologists and otorhinolaryngologists, often with the argument of a technically easier and less invasive procedure; however, it remains unclear whether this shift towards endoscopic techniques truly translates into better outcome quality...

The role of arthroscopic surgery for the treatment of various orthopedic pathologies has greatly improved during the last years. Recent publications showed that benign bone lesion may benefit from this minimally invasive surgical method, in order to minimize the invasiveness and the period of immobilization and to increase visualization. Unicameral bone cysts may be adequately treated by minimally invasive endoscopic surgery. The purpose of the current paper is to present the case report of a patient with a unicameral bone cyst of the calcaneus that underwent endoscopically assisted treatment with curettage and bone grafting with allograft from a bone bank, with emphasis on the surgical technique...

Open anterior repair for inguinal hernia offers several distinct advantages over endoscopic repair, especially when real-world effectiveness is taken into account. The learning curve for endoscopic techniques is long, whereas the Lichtenstein and other open tension-free techniques are easier to teach and replicate at all levels. The outcomes of Lichtenstein repairs for primary inguinal hernia as performed by non-experts and supervised residents are comparable to those of experts. Moreover, open tension-free repair does not require expensive instruments or dedicated equipment, other than the prosthetic mesh...

Gastric per oral endoscopic myotomy is a novel endoscopic technique, using mucosal incision and submucosal tunneling, to access and surgically divide the pyloric ring. It has been reported as a technically feasible procedure and minimally invasive therapy for refractory gastroparesis. We performed this procedure in a 63-year-old male patient with postoperative pylorospasm, with clinical success. Pylorospasm is one of pathophysiologic mechanisms underlying gastroparesis. As a subgroup of gastroparesis, pylorospasm should be identified to be an appropriate indication for gastric per oral endoscopic myotomy...

The goal of this work is to develop an innovative method that combines bioprinting and endoscopic imaging to repair tympanic membrane perforations (TMPs). TMPs are a serious health issue because they can lead to both conductive hearing loss and repeated otitis media. TMPs occur in 3 to 5% of cases after ear tube placement as well as in cases of acute otitis media (the second most common infection in pediatrics), chronic otitis media with or without cholesteatoma, or as a result of barotrauma to the ear. About 55,000 tympanoplasties, the surgery performed to reconstruct TMPs, are performed every year and the commonly used cartilage grafting technique has a success rate between 43% to 100%...

PURPOSE: TNF blockers are approved for intravenous or subcutaneous systemic therapy of many chronic inflammatory diseases. As it is not possible to achieve a sufficient local clinical improvement through systemic therapy in every patient, diverse approaches of topical therapy using TNF blockers have been investigated in recent years. METHODS: In this paper, we report on long-term clinical results of originator infliximab (IFX) injections into symptomatic combined scarring and inflammatory stenoses of the rectum in two patients with Crohn's disease...

Urethral stones can become impacted in the posterior urethra, typically presenting with varying degrees of acute urinary retention and lower urinary tract symptoms. These are traditionally treated in the inpatient setting, with external urethrotomy or endoscopic push-back of the calculus into the urinary bladder followed by cystolitholapaxy or cystolithotripsy. However, these methods are invasive, involve general anesthesia, and require radiation. In this report, we describe a simple, minimally invasive, and safe alternative technique to visualize and remove impacted prostatic urethral stones under the real-time guidance of transrectal ultrasonography (TRUS)...
