Front Med (Lausanne) 2023; 10:1226748. [PMID: 37881626 PMCID: PMC10595015 DOI: 10.3389/fmed.2023.1226748] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2023] [Accepted: 09/25/2023] [Indexed: 10/27/2023] Open
Abstract
This paper presents a comprehensive exploration of endoscopic technologies in clinical applications across seven tables, each focusing on a unique facet of the medical field. The discourse begins with a detailed analysis of pediatric endoscopes, highlighting their diagnostic capabilities in various conditions. It then delves into the specifications and applications of globally recognized capsule endoscopy devices. Additionally, the paper incorporates an analysis of advanced imaging techniques, such as Narrow Band Imaging (NBI), Flexible Spectral Imaging Color Enhancement (FICE), and i-scan, which are increasingly being integrated into ultrathin gastrointestinal (GI) endoscopes. Factors like technological capabilities, light source, camera technology, and computational constraints are evaluated to understand their compatibility with these advanced imaging techniques, each offering unique advantages and challenges in clinical settings. NBI, for instance, is lauded for its user-friendly, real-time enhanced imaging capabilities, making it effective for early detection of conditions like colorectal cancer and Barrett's esophagus. Conversely, FICE and i-scan offer high customizability and are compatible with a broader range of endoscope models. The paper further delves into innovative advances in movement control for Nasojejunal (NJ) feeding tube endoscopy, elucidating the potential of AI and other novel strategies. A review of the technologies and methodologies enhancing endoscopic procedure control and diagnostic precision follows, emphasizing image and video technologies in pediatric endoscopy, capsule endoscopes, ultrathin endoscopes, and their clinical applications. Finally, a comparative analysis of leading real-time video monitoring endoscopes in clinical practices underscores the continuous advancements in the field of endoscopy, ensuring improved diagnostics and precision in surgical procedures. Collectively, the comparative analysis presented in this paper highlights the remarkable diversity and continuous evolution of endoscopic technologies, underlining their crucial role in diagnosing and treating an array of medical conditions, thereby fostering advancements in patient care and clinical outcomes.

Direct endoscopic placement of percutaneous endoscopic gastrostomies with jejunal extension tubes (PEG-J) using ultra-thin endoscopes - long-term outcomes from a U.S. tertiary referral center. Surg Endosc 2022; 36:4233-4238. [PMID: 34642797 DOI: 10.1007/s00464-021-08757-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2021] [Accepted: 09/27/2021] [Indexed: 01/29/2023]
Abstract
INTRODUCTION Several techniques for PEG-J tube placement have been described, commonly requiring fluoroscopic guidance and/or fixation of the jejunostomy tube (J-tube) into the small intestine. We describe a modified technique for placing jejunostomy tubes under direct visualization through a PEG with the use of ultra-thin endoscopes and steel guidewire. METHODS A retrospective study at a single tertiary academic center evaluating patients who underwent PEG-J placement between 2010 and 2020. All PEG tubes were placed with a pull-through technique. The Olympus GIF-N180 endoscope was advanced through the PEG to the jejunum and a Savary-Gilliard guidewire was used for placement of the J-tube extension. RESULTS Fifty-eight patients underwent PEG-J placement (median age 61 years; women 52%). Surgically altered gastric anatomy was observed in 11 patients (19%). Median procedure time was 44 min for new PEG-J tube placement (range 26-103) and 20 min for placement of a J-tube extension through an existing PEG tube (range 9-86) or gastrostomy tract. Technical success rate was in 100%. Sixty-two repeat procedures were performed for J-tube exchange in 27 patients (46%, range 1-9 per patient), of which 51 procedures (82%) were done using the same technique. The most common indication for tube replacement was tube dysfunction (63%, n = 39). The median procedure time for tube exchange was 20 min (range 2-62). No major adverse events were encountered. CONCLUSION PEG-J tubes can be placed effectively, rapidly, and safely using an ultra-thin caliber endoscope and a stiff steel wire through the PEG tube or mature gastrostomy site, precluding the need for fluoroscopy or oral access. J-tubes can be easily replaced utilizing the same technique.

Short- and long-term outcomes from percutaneous endoscopic gastrostomy with jejunal extension. Surg Endosc 2016; 31:2901-2909. [PMID: 27796601 DOI: 10.1007/s00464-016-5301-3] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2016] [Accepted: 10/14/2016] [Indexed: 01/20/2023]
Abstract
BACKGROUND There is a paucity of data regarding the safety and efficacy of percutaneous endoscopic gastrostomy with jejunal extension (PEG-J). We evaluated adverse events related to PEG-J and determined the clinical impact of PEG-J in those with chronic pancreatitis (CP). METHODS This cohort study included all patients who underwent PEG-J placement in a tertiary-care academic medical center between 2010 and 2012. Main outcome measurements were (1) short- and long-term complications related to PEG-J and (2) changes in weight and hospitalizations during the 12-month period before and after PEG-J in the CP subgroup. RESULTS Of 102 patients undergoing PEG-J placement, the overall technical success rate was 97 %. During a median follow-up period of 22 months (1-46 months, n = 90), at least one tube malfunction occurred in 52/90 (58 %; 177 episodes) after a median of 53 days (3-350 days), requiring a median of two tube replacements. Short-term (<30 days) tube malfunction occurred in 28/90 (31 %) and delayed in 24/90 (27 %); these included dislodgement (29 %), clogging (26 %) and kinking (14 %). In the CP subgroup (n = 58), mean body weight (kg) (70 vs. 71, p = 0.06) and body mass index (kg/m2, 26 vs. 27, p = 0.05) increased post-PEG-J. Mean number of hospitalizations (5 vs. 2, p < 0.0001) and inpatient days per 12 months (22 vs. 12, p = 0.005) decreased. CONCLUSIONS While we observed no major complications related to PEG-J, half of patients had at least one episode of tube malfunction. In the CP subgroup, jejunal feeding via PEG-J significantly reduced the number of hospitalizations and inpatients days, while improving nutritional parameters.
