Background: A variety of surgical and nonsurgical management options for small renal masses (SRMs) now exist. Surgery in the form of partial nephrectomy (PN) has three different approaches. It is unclear which PN approach, if any, offers superior clinical outcomes. Aim: The aim of this study is to compare outcomes in patients with SRMs <4 cm undergoing PN through the open partial nephrectomy (OPN), laparoscopic partial nephrectomy (LPN), or robotic partial nephrectomy (RPN) approach and to establish the advantages and disadvantages of the various approaches...

BACKGROUND AND AIMS: The widespread use of peroral endoscopic myotomy (POEM) has revolutionized the management of esophageal motility disorders (EMDs). The introduction of an endoluminal functional lumen imaging probe (EndoFLIP) can serve as a complimentary diagnostic tool to assess the mechanical properties (i.e., pressure, diameter, distensibility and topography) of the esophagus. During EndoFLIP measurements, different anesthesia techniques may induce variable degrees of neuromuscular blockade, potentially affecting esophageal motility and altering the results of EndoFLIP metrics...

INTRODUCTION: The benefits of routine follow-up after treatment of primary laryngeal squamous cell carcinoma (LSCC) remain disputed. Guidelines worldwide are consensus-based, and evidence for specific subgroups is lacking. This study evaluates routine LSCC follow-up including flexible endoscopy for detecting locoregional recurrence (LRR). METHODS: A retrospective cohort of 413 LSCC patients treated between 2006 and 2012 was analysed. The cumulative risk of LRR was calculated...

Background: In recent years, we have witnessed an evolving landscape in the management of chronic pancreatitis (CP). Endoscopy plays a pivotal role in CP management. Because the management of CP is problematic, we aimed to review and evaluate the role of endoscopy in the management of CP. Methods: This study was carried out in patients with painful chronic calcific pancreatitis who were admitted to the Department of Gastroenterology at the Sher-I-Kashmir Institute of Medical Sciences (SKIMS), Srinagar. This was an observational prospective study...

BACKGROUND: Patients may experience anxiety, discomfort, and pain during endoscopy, which cannot be tolerated without sedative drugs. OBJECTIVES: This study aimed to compare the sedative effects of dexmedetomidine and midazolam on patients undergoing endosonography outside the operating room. METHODS: This randomized, double-blind clinical trial was conducted on 126 patients aged 18 - 65 years old with American Society of Anesthesiologists (ASA) physical status I - II undergoing elective endosonography...

BACKGROUND AND AIMS: Inflammatory bowel disease (IBD) is associated with high rates of post-colonoscopy colorectal cancer (PCCRC), but further in-depth qualitative analyses are required to determine whether they result from inadequate surveillance or aggressive IBD cancer evolution. METHODS: All IBD patients who had a colorectal cancer (CRC) diagnosed between January 2015 to July 2019 and a recent (<4 years) surveillance colonoscopy at one of four English hospital trusts underwent root cause analyses as recommended by the World Endoscopy Organisation to identify plausible PCCRC causative factors...

BACKGROUND:  Screen-detected colorectal cancers (CRCs) are often treated less invasively than stage-matched non-screen-detected CRCs, but the reasons for this are not fully understood. This study evaluated the treatment of stage I CRCs detected within and outside of the screening program in the Netherlands. METHODS : Data from the Netherlands Cancer Registry for all stage I CRCs diagnosed between January 1, 2008 and December 31, 2020 were analyzed, comparing patient, tumor, and treatment characteristics of screen-detected and non-screen-detected stage I CRCs...

INTRODUCTION: Holmium laser lithotripsy is a standard energy source used for treatment of kidney stones during flexible ureteroscopy. Efficiency of laser surgery may be affected by patient and operator characteristics or perioperative management. Here, we sought to examine intraoperative data from patients undergoing high frequency dusting with high-powered holmium laser lithotripsy to evaluate surgical and demographic factors associated with lasing efficiency. METHODS: A total of 82 intraoperative reports were analyzed from an ongoing laser lithotripsy clinical trial evaluating the Lumenis Pulse™ 120H holmium laser with renal stones up to 20mm in diameter with and without Moses 2...

The main objectives of interventional stone treatment are stone removal, symptom elimination, and kidney function preservation. After treatment of kidney stones (extracorporeal shock wave lithotripsy [ESWL], or endoscopy), fragments may remain in the kidney, either deliberately left in place or due to treatment failure (i.e. residual stone [RS], resistant to ESWL, left or inaccessible by endoscopy), or due to failure to eliminate the obtained fragments (i.e. residual fragments [RF]). Their management may differ...

BACKGROUND: Inflammatory Bowel Diseases (IBD) are known to occur in association with Hirschsprung disease (HSCR). Most of cases are represented by Crohn Disease (CD) occurring in patients with Total Colonic Aganglionosis (TCSA) with an estimated prevalence of around 2%. Based on these considerations and on a number of provisional data belonging to our Center for Digestive Diseases, we developed a unicentric cross-sectional observational study aimed at describing phenotype, genotype, pathology and metagenomics of all patients with TCSA and Crohn-like lesions...

BACKGROUND AND STUDY AIMS: For a highly selected group of patients with unresectable perihilar cholangiocarcinoma (pCCA) liver transplantation (LT) is a treatment option. The Dutch screening protocol comprises non-regional lymph node (LN) assessment by endoscopic ultrasound (EUS) and whenever LN metastases are identified, further LT screening is precluded. The aim of this study is to investigate the yield of EUS in patients with pCCA who are potentially eligible for LT. METHODS: In this retrospective, nationwide cohort study, all consecutive patients with suspected unresectable pCCA who underwent EUS in the screening protocol for LT were included from 2011-2021...

Aims: This study aimed to review our surgical experience of laparoscopic adrenalectomy (LA) for adrenal masses in the pediatric age group. Materials and Methods: The electronic medical records of all patients younger than 18 years of age who underwent LA between 2016 and 2023 were retrospectively reviewed. Children with adrenal tumors localized to the site of origin without evidence of encasement of major vasculature or involvement of adjacent organs were considered for LA. Patients with diagnosis of malignant adrenal tumor on preoperative work-up underwent open adrenalectomy...

INTRODUCTION: Parastomal hernias are frequent and highly recurrent. The sandwich technique is a combination of the keyhole and Sugarbaker techniques, using a double intraperitoneal mesh. The objective of this study was to assess the outcomes of the sandwich technique, specifically focusing on recurrence rates. MATERIALS AND METHODS: Observational retrospective study conducted in two tertiary referral centers in Catalonia, Spain. All consecutive patients who underwent parastomal hernia repair using the sandwich technique between 1st January 2016 and 31st December 2021 were included...

BACKGROUND: Although propofol is widely used for gastrointestinal endoscopic sedation, cardiopulmonary adverse events remain common. Ciprofol is a new intravenous anaesthetic agent demonstrating respiratory and hemodynamic stability. AIMS: This study aimed to clarify the benefits of ciprofol combined with alfentanil in bidirectional endoscopy (esophagogastroduodenoscopy followed by colonoscopy) to reduce adverse events and improve post-endoscopic recovery. METHODS: A total of 185 patients scheduled to undergo bidirectional endoscopy were randomly divided into two groups: ciprofol combined with alfentanil or propofol combined with alfentanil...

BACKGROUND AND AIMS: The COVID-19 pandemic disrupted endoscopy practices creating unprecedented decreases in cancer screening and surveillance services. We aimed to assess the impact of the pandemic on the proportion of patients diagnosed with Barrett's esophagus (BE) and BE-related dysplasia and adherence to established quality indicators. METHODS: Data from all esophagogastroduodenoscopies (EGDs) in the GI Quality Improvement Consortium, a national repository of matched endoscopy and pathology data, were analyzed from 1/2018 - 12/2022...

Background: Frailty is a recent multidimensional concept of a contemporary growing interest for understanding the complex health status of elderly population. We aimed to assess the impact of frailty scores on the outcome and complication rate of holmium laser enucleation of prostate (HoLEP). Methods: A 7-year data of HoLEP patients in a single tertiary referral center were reviewed. The preoperative, operative, early, and late postoperative outcome data were collected and compared according to the preoperative frailty scores...

UNLABELLED: There is a generally recognized need for a morphological assessment of the individual risk of developing gastric cancer in a patient with chronic gastritis, according to the OLGA system (Operative Link for Gastritis Assessment). At the same time, the role of assessing the biopsy from the incisura angularis remains controversial. The aim of our study was to assess the value of incisura angularis biopsy in staging gastritis according to the OLGA system by examining the atrophic and inflammatory changes in the antrum, incisura angularis, and body...

In the field of medical image analysis, accurate lesion segmentation is beneficial for the subsequent clinical diagnosis and treatment planning. Currently, various deep learning-based methods have been proposed to deal with the segmentation task. Albeit achieving some promising performances, the fully-supervised learning approaches require pixel-level annotations for model training, which is tedious and time-consuming for experienced radiologists to collect. In this paper, we propose a weakly semi-supervised segmentation framework, called Point Segmentation Transformer (Point SEGTR)...

Background and objectives Propofol-based sedation is one of the most commonly used methods for endoscopic retrograde cholangiopancreatography (ERCP). The commonest complications during ERCP are in the form of adverse cardiopulmonary events as a result of sedation. Etomidate has a more stable cardiovascular and respiratory profile than propofol and has been used for sedation in simple gastrointestinal endoscopy but has not been studied for procedural sedation in ERCP. The objective of the present study was to compare the safety and feasibility of etomidate and propofol for sedation during ERCP procedures...
