INTRODUCTION: Advanced endoscopic therapy techniques have been developed and have created alternative treatment options to surgical therapy for several gastrointestinal diseases. This work will focus on new endoscopic tools for special indications of advanced endoscopic resections (ER), especially endoscopic submucosal dissection (ESD), which were developed in our institution. This paper aims to analyze these specialized instruments and identify their status. METHODS: Initially, the technical process of ESD was analyzed, and the following limitations of the different endoscopic steps and the necessary manipulations were determined: the problem of traction-countertraction, the grasping force needed to pull on tissue, the instrument tip maneuverability, the limited angulation/triangulation, and the mobility of the scope and instruments...

INTRODUCTION: Gas leaks polluting the operating room are common in laparoscopy. Studies defining methods for sensitive leak characterisation and mechanical mitigation in real world settings are, however, lacking. METHODS: Mobile optical gas imagers (both a miniaturised Schlieren system and sensitive tripod-mounted near-infrared carbon dioxide camera (GF343, FLIR)) prospectively defined trocar-related gas leaks occurring either spontaneously or with instrumentation during planned laparoscopic surgery at three hospitals...

INTRODUCTION: The number of patients with hiatal hernia has increased. Paraesophageal and mixed hiatal hernias are absolute indications for surgical treatment due to the possibility of blood flow disturbances to the stomach and other organs. CASE PRESENTATION: A 77-year-old woman with a history of type IV esophageal hiatal hernia (under observation), multiple operations presented with a chief complaint of vomiting. She was diagnosed with a type IV esophageal hiatal hernia with incarceration of the duodenal bulb into the mediastinum...

Background: Total extraperitoneal approach for laparoscopic inguinal hernia repair (L-TEP) allows for better dissection, lesser chance of bowel injury, and quicker operating time. However robotic groin hernia repair is currently performed only through transabdominal route as it allows for more mobility of the arms. This study is aimed at studying the feasibility and outcomes of robotic totally extraperitoneal (R-TEP). Methods: A prospective nonrandomized comparative study was conducted to compare R-TEP with L-TEP...

BACKGROUND: Patient engagement technologies (PET) are an area of growing innovation and investment, but whether PET use in the setting of electronic medical record (EMR) supported patient portals are associated with improved outcomes is unknown. Therefore, we assessed PET and EMR activation among patients undergoing elective colorectal surgery on an enhanced recovery pathway. METHODS: We identified adults undergoing elective colorectal surgery between 1/2017 and 7/2021...

BACKGROUND: Percutaneous endoscopic gastrostomy (PEG) is commonly chosen for long-term enteral nutrition support. However, common complications of PEG include wound infection, leakage, obstruction, bleeding, dislodgement, pneumonia, peritonitis, and more. The anticipation of these complications by both patients and their family caregivers underscores the essential requirement of ongoing technical guidance for the daily care of PEG and the adoption of preventative strategies. OBJECTIVE: This study aimed to establish and compare a health education program utilizing a tracking system for PEG using a mobile app (PEG app) and instant messaging software versus a paper-based health education program with instant messaging software...

Foregut surgical techniques have advanced significantly over the years and have become increasingly popular. However, new challenges and technical considerations have arisen when dealing with reoperation for complications or surgical failure. This study focuses on the technical considerations and approach when dealing with reoperative foregut surgery, particularly redo hiatal hernia repair. We describe our approach starting from the preoperative workup to the procedural steps of the surgery. The present study describes the main steps for robotic reoperative hiatal hernia repair in a patient who had previously undergone laparoscopic hiatal hernia repair with Nissen fundoplication but did not present a recurrence of reflux and dysphagia symptoms...

BACKGROUND: In pancreaticoduodenectomy (PD), the approach to superior mesenteric artery (SMA) is a critical process that supports adequate surgical margins and radicality for pancreatic tumors. In most of the reports on laparoscopic PD, the right-sided approach in which the jejunum is pulled out to the right side for peri-SMA dissection is used, since the left side of the SMA is difficult to dissect, and the only way to do this is to dissect the vein first. METHODS: We devised a method to simplify and safely perform peri-SMA dissection by reversing the process, starting from the left side of the SMA...

OBJECTIVE: This study aimed to construct a decision aid to estimate the likelihood of independence with a prosthesis following rehabilitation for limb loss secondary to advanced ischaemia (acute or chronic limb threatening ischaemia) or diabetic foot disease (DFD). A secondary aim was to determine whether prosthetic independence is a surrogate marker of long term survival. METHODS: A retrospective cohort study of a prospectively maintained database of unilateral amputations due to ischaemia or DFD entering rehabilitation between 2007 and 2020 was performed...

Patients with multiple system atrophy (MSA) frequently experience dysphagia but only few studies analyzed its characteristics. The aim of this study was to describe the swallowing characteristics in these patients using fiberoptic endoscopic evaluation of swallowing (FEES). In addition, the swallowing abilities in patients with predominantly cerebellar MSA (MSA-C) and predominantly parkinsonian MSA (MSA-P) were compared. Twenty-five patients with MSA (16 MSA-P and 9 MSA-C) were enrolled. Clinical data including age, sex, functional oral intake scale (FOIS) score, body mass index (BMI) and the results of the global disability-unified MSA rating scale (GD-UMSARS) were collected...

Purpose: Retrograde intrarenal surgery (RIRS) has been accepted as a first-line therapeutic option for kidney stones <2 cm. Renal mobility might be a challenging situation for the surgeon targeting the laser, thereby limiting the renal mobility during surgery might affect the surgical success. The main objective of the present trial was to evaluate the effect of two different ventilation modes on the efficacy and safety of RIRS performed under general anesthesia. Materials and Methods: The patients undergoing RIRS from January 2023 to April 2023 were prospectively enrolled in the trial...

BACKGROUND: The results of a recent pilot study suggest that steerable ureteroscopic renal evacuation (SURE) is safe and more effective in stone removal than basketing following laser lithotripsy. The objective of this retrospective study was to further assess the safety and efficacy of SURE using the CVAC® Aspiration System (Calyxo, Inc., Pleasanton, CA) in patients with large stone burdens. MATERIALS AND METHODS: Patients with a baseline stone burden of ≥10 mm who underwent SURE were identified...

BACKGROUND: This study aimed to compare the outcomes of non-intubated video-assisted thoracic surgery (N-VATS) and intubated video-assisted thoracic surgery (I-VATS) for primary spontaneous pneumothorax (PSP). MATERIALS AND METHODS: We retrospectively analyzed 120 consecutive patients who underwent VATS for PSP. The patients were divided into N-VATS and I-VATS groups. Demographics, clinical characteristics, postoperative results, pain scores, follow-up results, and management were evaluated and compared between the groups...

BACKGROUND AND AIMS: Duodenal polyps have a reported incidence of 0.3% to 4.6%. Sporadic, nonampullary duodenal adenomas (SNDAs) comprise less than 10% of all duodenal polyps, and ampullary adenomas are even less common. Nonetheless, the incidence continues to rise because of widespread endoscopy use. Duodenal polyps with villous features or those that are larger than 10 mm may raise concern for malignancy and require removal. We demonstrate endoscopic resection of SNDAs and ampullary adenomas using some of our preferred techniques...

INTRODUCTION: At our institute, we usually perform robot-assisted surgery for rectal cancer as minimally invasive surgery. It is necessary to recognize the tumor edge accurately when deciding where to place the distal cutting line of the rectum. In this article, with video presentation, we demonstrate the usefulness of intraoperative sonography (IOUS) for detecting the rectal tumor site in robotic surgery. This is the first report to discuss the IOUS image of rectal cancer. MATERIALS AND SURGICAL TECHNIQUE: After mobilization of the rectum in robotic procedure, the rectum should be straightened...

We report a case of Streptococcus mitis endocarditis associated with early gastric carcinoma. A 71-year-old man who had been diagnosed with aortic regurgitation (AR) two years previously was referred for valve surgery and evaluation of elevated inflammatory markers. Four months previously, atrophic gastritis, early gastric adenocarcinoma, and colon polyp had been identified in the patient during endoscopy. However, Helicobacter pylori testing was negative. On admission, he had no dental diseases or recent oral procedures...

We report our experience in a patient with adenoma located in the horizontal part of the duodenum, which was effectively treated with the transmesenteric laparoscopic endoscopic cooperative surgery (LECS) approach. This approach, which entails incising the mesentery of the colon, simplified laparoscopic access to the horizontal part of the duodenum, which was minimally mobilized. Thus, the bulb and descending part of the duodenum were fixed to the retroperitoneum, facilitating stable handling of the endoscope and enabled safe and effective excision of an adenoma located in the horizontal part of the duodenum...

Background: An aberrant vascular anatomy might present a technical pitfall for biliary atresia (BA) surgery. The purpose of this study was to report the rare cases and discuss the significance and management strategy for BA with an aberrant right hepatic artery (ARHA) by laparoscopic Kasai procedure in children. Methods: The subjects for this study were 10 consecutive type III BA patients with an ARHA who had laparoscopic Kasai procedure at our institute between January 2012 and August 2021. The common bile duct was mobilized between the right hepatic artery and the right branch of portal vein, and then lifted to the liver hilum...

Complete control of a beam pattern requires not only projecting a two-dimensional (2D) pattern but also focusing on a three-dimensional (3D) point cloud, which is typically achieved utilizing holography under the framework of diffraction. We previously reported direct focusing from on-chip size surface-emitting lasers that utilize a holographically modulated photonic crystal cavity based on 3D holography. However, this demonstration was of the simplest 3D hologram with a single point and single focal length, and the more typical 3D hologram with multiple points and multiple focal lengths has not yet been examined...

INTRODUCTION: Kidney stone disease (KSD) is a common urological condition that often requires long-term care. Mobile health (mHealth) and eHealth technologies have the potential to enhance chronic disease management and behavioral change. To assess opportunities to apply these tools to improve KSD treatment and prevention, we aimed to assess current evidence on the use, benefits, and limitations of mHealth and eHealth in KSD. METHODS: We performed a systematic review of primary research studies of mHealth and eHealth in the evaluation and management of KSD...
