Differentiating between the cases of megaureter that require surgery and the ones in whom treatment can be delayed is challenging. A large number of surgical techniques for the treatment of POM been proposed aiming mainly to reduce renal damage by relieving the affected ureter. Resection of the affected ureteral segment followed by vesicoureteral reimplantation either with or without reduction ureteroplasty is the classic treatment, however posing a high rate of complications when performed in patients aged less than one year...

We show the use of a new endoscopic drill for the management of web-like tracheal stenosis. Our device creates radial holes within stenosis that facilitate the use of scissors for cutting the scar tissue and the subsequent mechanical dilatation.

BACKGROUND: Banded-gastric bypass is a highly effective bariatric procedure, yet the possibility of band erosion remains a significant drawback. Surgical removal of eroded bands may be associated with significant morbidity. In this study, we assess the efficacy and safety of a solely peroral endoscopic approach for the management of eroded bands in patients with a banded-gastric bypass. MATERIALS AND METHODS: Starting January 2012, all patients with banded-gastric bypass and an eroded band were subjected to an attempt at peroral endoscopic removal using endoscopic scissors and/or argon plasma coagulation (APC), regardless of the circumference of band eroding inside the lumen...

Diagnosing pleural effusion is challenging, especially in patients with malignant or benign fibrothorax, which is difficult to sample using standard flexible forceps (SFF) via flex-rigid pleuroscopy. An adequate sample is crucial for the differential diagnosis of malignant fibrothorax (malignant pleural mesothelioma, metastatic lung carcinoma, etc.) from benign fibrothorax (benign asbestos pleural disease, tuberculous pleuritis, etc.). Novel biopsy techniques are required in flex-rigid pleuroscopy to improve the sample size and quality...

BACKGROUND: The incidence of caudal stent migration in high tracheal stenting is 13-21% and is common with silicone stents. This can lead to major problems, including emergency repeat procedures. Several antimigration methods are described, but have limitations in terms of their success rate, availability, cost or ease of the procedure. OBJECTIVES: We describe an innovative method of stent migration prevention using a simple percutaneous anchoring "hitch stitch", validated in a large series...

BACKGROUND AND AIM: Colorectal endoscopic submucosal dissection (C-ESD) is recognized as a difficult procedure. Recently, scissors-type knives were launched to reduce the difficulty of C-ESD. The aim of this study was to evaluate the efficacy and safety of the combined use of a scissors-type knife and a needle-type knife with a water-jet function (WJ needle-knife) for C-ESD compared with using the WJ needle-knife alone. METHODS: This was a prospective randomized controlled trial in a referral center...

BACKGROUND AND STUDY AIMS: Endoscopic submucosal dissection (ESD) for early gastric cancer (EGC) is technically difficult for beginners. Few comparative studies of technical feasibility, efficacy, and safety using various devices have been reported. This study evaluated the feasibility, efficacy, and safety of ESD for EGC < 2 cm using grasping-type scissors forceps (GSF) or insulated-tip knife (IT2) for three resident endoscopists. PATIENTS AND METHODS: This was a randomized phase II study in a cancer referral center...

BACKGROUND: Sistrunk operation of the thyroglossal duct is a procedure for the removal of a cyst, the middle part of the hyoid bone and tract towards the foramen caecum. Unavoidably, this procedure results in a scar on the skin in the neck area. By performing a bilateral areolar endoscopic Sistrunk operation, this study is the first to develop a procedure that can solve the aesthetic problem. This operation results in both an excellent cosmetic result and the successful treatment of TGDC...

INTRODUCTION: We previously reported cases of laparoendoscopic single-site nephrectomy performed through an umbilical or pararectal incision. To improve cosmesis and operability, we performed three Pfannenstiel laparoendoscopic reduced-port nephrectomies. MATERIALS AND SURGICAL TECHNIQUE: In the first case, a GelPOINT access was placed through a 2-cm umbilical incision, and two additional 3-mm trocars were inserted. The specimen was extracted through a 4-cm Pfannenstiel incision...

BACKGROUND: Transanal endoscopic surgery (TES) can be technically difficult due to the constraints of operating through a narrow proctoscope channel. In this study, we compared the performance of surgical novices using instruments with and without articulating shafts to perform a simulated TES task. METHODS: Medical students each performed 10 repetitions of the Fundamentals of Laparoscopic Surgery circle-cut task. Participants were randomized into 3 groups: 2 performed the task through a TES proctoscope using scissors with either a rigid (TES-R) or articulating (TES-A) shaft...

PURPOSE: Isolated tenotomy of the long head of the biceps (LHB) is known to improve function in patients with massive and non-reparable cuff tears without osteoarthritis. This two step cadaveric study was performed with the purpose to identify the best surgical technique for isolated LHB tenotomy under USG guidance (pilot study) and evaluate its feasibility (subsequent study). METHODS: Pre-operative ultrasonographic evaluation of the rotator cuff was performed and any specimens whose long head of the biceps was not found to be intact during the pre-operative ultrasound evaluation were excluded...

BACKGROUND AND AIMS: Flexible endoscopic treatment of symptomatic Zenker's diverticulum (ZD) is an established treatment option. This study reports the first large cohort of ZD patients treated with the stag beetle knife (sb knife, a new scissor-like device) regarding feasibility, safety, and sustainability of mucomyotomy using this technique. METHODS: From August 2013 to January 2016, n = 52 patients (pts) were treated at Klinikum Augsburg, a tertiary referral center, with the sb knife junior or standard...

Inguinal lymphadenectomy is the indicated procedure in the regional lymph node management for patients with lower limb melanoma and positive nodes. This procedure is commonly associated with surgical site complications. Video endoscopic inguinal lymphadenectomy is a minimally invasive alternative with oncological principles and lower wound-related morbidity. Incorporation of robotic surgery with optimal vision and great maneuverability would offer great advantages. A 42-year-old male patient was diagnosed with acral lentiginous melanoma and palpable inguinal nodes T2 N1 M0...

AIM: To apply the laparoscopic and endoscopic cooperative surgery concept, we investigated whether endoscopic cholecystectomy could be performed more safely and rapidly via only 1 port or not. METHODS: Two dogs (11 and 13-mo-old female Beagle) were used in this study. Only 1 blunt port was created, and a flexible endoscope with a tip attachment was inserted between the fundus of gallbladder and liver. After local injection of saline to the gallbladder bed, resection of the gallbladder bed from the liver was performed...

Tracheal resection and primary anastomosis is the treatment of choice for the management of benign tracheal stenoses. Rigid endoscopy with laser-assisted mechanical dilatation is an alternative to surgery and helps to improve symptoms and quality of life in patients unfit for surgery. Here, we describe the treatment of a simple web-like stenosis, using a new endoscopic hand drill that was assembled by sharpening the blunt tip of a standard endoscopic cotton applicator. The bronchoscopy was positioned proximally to the stenotic lesion and radial holes were made at 12, 3 and 9 o'clock...

The endoscopic method is used to treat suprasellar arachnoid cysts (SACs) but it is sometimes difficult to make sufficiently sized fenestrations. Creating a larger fenestration on the cyst wall is preferable to prevent closure of the stoma. In this paper, we report a novel endoscopic approach for SAC treatment in which we use bilateral burr holes to achieve a more extensive cyst fenestration. A 7-year-old girl was referred to our hospital because of incidentally detected hydrocephalus by computed tomography scans...

OBJECTIVE: Open decompression of the superficial radial nerve is performed at the distal forearm in cases of circumscript entrapment. Broad-based entrapments can be treated by endoscopically assisted decompression. INDICATIONS: Entrapment of the nerve along its course between the brachioradialis and extensor carpi radialis longus muscles or tendons. Persistent neuropathic pain with Tinel's sign. Numbness distal to the entrapment in accordance to nerval innervation...
