[PMID: 39174707 DOI: 10.1007/s00464-024-11013-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2024] [Accepted: 06/30/2024] [Indexed: 08/24/2024]
Abstract
BACKGROUND Transcolonic endoscopic appendectomy (TEA) is rapidly evolving and has been reported as a minimally invasive alternative to appendectomy. We aimed to characterize the feasibility and safety of a novel unassisted single-channel TEA. METHOD We retrospectively investigated 23 patients with appendicitis or appendiceal lesions who underwent TEA from February 2016 to December 2022. We collected clinicopathological characteristics, procedure‑related parameters, and follow‑up data and analyzed the impact of previous abdominal surgery and traction technique. RESULTS The mean age was 56.0 years. Of the 23 patients with appendiceal lesions, fourteen patients underwent TEA and nine underwent traction-assisted TEA (T-TEA). Eight patients (34.8%) had previous abdominal surgery. The En bloc resection rate was 95.7%. The mean procedure duration was 91.1 ± 45.5 min, and the mean wound closure time was 29.4 ± 18.6 min. The wounds after endoscopic appendectomy were closed with clips (21.7%) or a combination of clip closure and endoloop reinforcement (78.3%), and the median number of clips was 7 (range, 3-15). Three patients (13.0%) experienced major adverse events, including two delayed perforations (laparoscopic surgery) and one infection (salvage endoscopic suture). During a median follow-up of 23 months, no residual or recurrent lesions were observed, and no recurrence of abdominal pain occurred. There were no significant differences between TEA and T-TEA groups and between patients with and without abdominal surgery groups in each factor. CONCLUSION Unassisted single-channel TEA for patients with appendiceal lesions has favorable short- and long-term outcomes. TEA can safely and effectively treat appendiceal disease in appropriately selected cases.

Abstract
Prevention of colorectal cancer (CRC) depends largely on the detection and removal of colorectal polyps. Despite the advances in endoscopic techniques, there are still a subgroup of polyps that cannot be treated purely by endoscopic approach, which comprise of about 10-15% of all the polyps. These so-called "difficult colorectal polyps" are polyps with large size, morphology, at difficult location, scarring or due to recurrence, which have historically been managed by surgical segmental resection. In treating benign difficult colorectal polyps, we have to balance the operative risks and morbidities associated with surgical segmental resection. Therefore, combined endoscopic and laparoscopic surgery (CELS) has been developed to remove this subgroup of difficult benign polyps. We review the currently use of CELS for difficult benign colorectal polyps which includes laparoscopy-assisted endoscopic polypectomy (LACP), full-thickness laparo-endoscopic excision (FLEX) and colonoscopy-assisted laparoscopic wedge resection (CAL-WR).

Abstract
Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract, primarily arising from the stomach. With the widespread utilization of and technical advancements in endoscopy, gastric GISTs are being increasingly detected at an early stage, enabling complete endoscopic resection. Endoscopic full-thickness resection (EFTR) is an advanced technique that has been recognized as a treatment tool for neoplasms in the digestive tract in selected patients. Although a number of methods are available, closing large iatrogenic defects after EFTR can be a concern in clinical practice. If this potential problem is appropriately solved, patients with gastric GISTs would be suitable candidates for resection utilizing this technique. To our knowledge, this is the first study to propose omental patching and purse-string endosuture closure following EFTR as a feasible endoscopic option in patients with gastric GISTs.

Abstract
Recent advances in minimally invasive endoscopic approaches have pushed the boundaries of well-established resection techniques for therapeutic and diagnostic applications. Endoscopic full thickness resection techniques are a key development in the management of challenging epithelial and subepithelial lesions that are not amenable to conventional endoscopic resection methods and previously required a surgical approach. Endoscopic full thickness biopsy represents a paradigm shift in tissue acquisition and will enhance our understanding of the pathophysiology, and guide therapy, of gastrointestinal neuromuscular diseases, as well as other inflammatory and neoplastic conditions. This review highlights current tools and techniques available for endoscopic full thickness resection and biopsy, as well as outcomes from such interventions.

Abstract
PUPRPOSE Benign polyps that are technically challenging and unsafe to remove via polypectomy are known as complex polyps. Concerns regarding safety and completeness of resection dictate they undergo advanced endoscopic techniques, such as endoscopic mucosal resection or surgery. We provide a comprehensive overview of complex polyps and current treatment options. METHODS A review of the English literature was conducted to identifyarticles describing the management of complex polyps of the colon and rectum. RESULTS Endoscopic mucosal resection is the standard of care for the majority of complex polyps. Only polyps that fail endoscopic mucosal resection or are highly suspicious of invasive cancer but which cannot be removed endoscopically warrant surgery. CONCLUSION Several factors influence the treatment of a complex polyp; therefore, there cannot be a "one-size-fitsall" approach. Treatment should be tailored to the lesion's characteristics, the risk of adverse events, and the resources available to the treating physician.

Abstract
Conventional endoscopic resection techniques such as endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD) are powerful tools for the treatment of gastrointestinal (GI) neoplasms. However, those techniques are limited to the superficial layers of the GI wall (mucosa and submucosa). Lesions without lifting sign (usually arising from deeper layers) or lesions in difficult anatomic positions (appendix, diverticulum) are difficult - if not impossible - to resect using conventional techniques, due to the increased risk of complications. For larger lesions (>2 cm), ESD appears to be superior to the conventional techniques because of the en bloc resection, but the procedure is technically challenging, time consuming, and associated with complications even in experienced hands. Since the development of the over-the-scope clips (OTSC), complications like bleeding or perforation can be endoscopically better managed. In recent years, different endoscopic full-thickness resection techniques came to the focus of interventional endoscopy. Since September 2014, the full-thickness resection device (FTRD) has the CE marking in Europe for full-thickness resection in the lower GI tract. Technically the device is based on the OTSC system and combines OTSC application and snare polypectomy in one step. This study shows all full-thickness resection techniques currently available, but clearly focuses on the experience with the FTRD in the lower GI tract.

Abstract
Secondary prevention of colorectal cancer relies on effective screening through colonoscopy and polypectomy. Resection of some polyps can present technical challenges particularly when polyps are large, flat, or behind colonic folds. Laparoscopy as an adjunct to endoscopy can aid in removing difficult colonic polyps without subjecting patients to radical segmental colectomy. Hybrid laparoendoscopic techniques are increasingly reported in literature as alternatives to segmental colectomy for the treatment of polyps that have a high likelihood of being benign. Laparoscopic-assisted colonoscopic polypectomy is the most frequently utilized technique; it harnesses the power of laparoscopy to aid endoscopic polypectomy by flattening folds, mobilizing flexures, and providing retraction. Colonoscopy-assisted laparoscopic wedge and transluminal resection are often reported in older studies and use the visualization provided by intraoperative colonoscopy to guide colonic resection that is limited to the area of the polyp. Laparoscopic-assisted endoscopic full-thickness resection (EFTR) is a relatively recent technique that provides laparoscopic monitoring of EFTR of polyp as well as endoscopic closure of the ensuing defect. Minimally invasive segmental colectomy based on oncologic principles should be utilized when none of the previous techniques are suitable or when malignancy is strongly suspected. The combined use of laparoscopy and endoscopy can expand the endoscopist's armamentarium when dealing with the most challenging polyps, while serving the patients' best interest by limiting the extent of colon resection.

Conventional endoscopic resection techniques such as endoscopic mucosal resection or endoscopic submucosal dissection are powerful tools for treatment of gastrointestinal neoplasms. However, those techniques are restricted to superficial layers of the gastrointestinal wall. Endoscopic full-thickness resection (EFTR) is an evolving technique, which is just about to enter clinical routine. It is not only a powerful tool for diagnostic tissue acquisition but also has the potential to spare surgical therapy in selected patients. This review will give an overview about current EFTR techniques and devices.

Abstract
BACKGROUND The benefit of endoscopic full-thickness resection is the improved diagnostic work-up with an integral wall specimen which allows a precise determination of the tumor or its precursor and its infiltration depth into the wall. MATERIALS AND METHODS A new endoscopic full-thickness resection device (FTRD), which is a combination of a modified over-the-scope-clip (OTSC) system with an electrocautery snare, has been tested in an experimental setting. In eleven pigs, divided into three groups, endoscopic full-thickness resection was performed in the colon at one or two sites, respectively. Seven days (n = 7) or 28 days (n = 4) after the intervention, the animals were euthanized following endoscopic examination of the resection and clip application sites. Furthermore, two different clips were tested during these animal trials in order to evaluate the most effective clip design. RESULTS The average diameter of the tissue resected with the FTRD was 3.1, 3.6, and 5.4 cm in the three groups. On follow-up endoscopy 7 days after the intervention, fibrin coating and stool residues were found at all clips, causing minor inflammatory reactions. However, the colon wall under the clip was non-inflamed. After 28 days, the serosa had primarily healed in all cases. There were also stool residues at all clips; however, no acute inflammatory reactions were seen anymore, due to complete healing. Histological assessment did not show any signs of dehiscence in the region of the scar, or ischemia in the clip area. In addition, no wound infections, such as abscess formation, were observed. CONCLUSIONS This study demonstrates the safety and efficacy of the clip-and-cut technique using the new FTRD system. With the device, a local full-thickness colon resection can be easily created, and the resulting wall defect is reliably sealed by the endoluminal application of a modified OTSC clip.

Abstract
The major role of colonoscopy with polypectomy in reducing the incidence of and mortality from colorectal cancer has been firmly established. Yet there is cause to be uneasy. One of the most striking recent findings is that there is an alarmingly high incomplete polyp removal rate. This phenomenon, together with missed polyps during screening colonoscopy, is thought to be responsible for the majority of interval cancers. Knowledge of serrated polyps needs to broaden as well, since they are quite often missed or incompletely removed. Removal of small and diminutive polyps is almost devoid of complications. Cold snare polypectomy seems to be the best approach for these lesions, with biopsy forcep removal reserved only for the tiniest of polyps. Hot snare or hot biopsy forcep removal of these lesions is no longer recommended. Endoscopic mucosal resection and endoscopic submucosal dissection have proven to be effective in the removal of large colorectal lesions, avoiding surgery in the majority of patients, with acceptably low complication rates. Variants of these approaches, as well as new hybrid techniques, are being currently tested. In this paper, we review the current status of the different approaches in removing polypoid and nonpolypoid lesions of the colon, their complications, and future directions in the prevention of colorectal cancer.

Abstract
GOALS The aim of this study was to evaluate the combination of endoscopic ultrasonography (EUS) and computed tomography (CT) in predicting the maneuvers for therapeutic endoscopy for gastrointestinal submucosal tumors (SMTs). METHODS Patients with SMTs, who were scheduled for endoscopic resection, were randomized to preoperative performance of both EUS and CT (group A) or EUS only (group B). The following data were collected: therapeutic maneuvers, duration of procedure, dose of propofol, resected lesion size, and complications. RESULTS A total of 36 patients were included in group A and 36 patients were included in group B. Endoscopic submucosal excavation was performed in 43 patients, endoscopic full-thickness resection in 18 patients, and submucosal tunneling endoscopic resection in 11 patients. No significant differences were observed between the two groups (P>0.05). The coincidence rate between the preoperative program and the actual endoscopic procedures in group A was higher than that in group B (83.3 vs. 61.1%, P<0.05). The procedural time in group A was less than that in group B (39.36±17.83 vs. 48.06±12.03 min, P<0.05), and the dose of propofol in group A was less than that in group B (249.18±125.12 vs. 304.16±102.61 mg, P<0.05). The mean resected lesion size was 2.32±1.46 cm in group A and 2.12±0.75 cm in group B, without differences (P>0.05). A total of 14 cardiopulmonary complications and seven endoscopic complications occurred, without significant differences between the two groups (P>0.05). CONCLUSION EUS combined with CT can better evaluate SMTs compared with EUS only in predicting the maneuvers for therapeutic endoscopy.

Abstract
The traditional approach to surgical resection of colonic cancer involves removal of the primary tumor together with the associated lymphovascular pedicle. In an attempt to improve oncological outcomes, several groups have recently published data describing improved outcomes with a more radical surgical approach termed complete mesocolic excision (CME) with central vessel ligation (CVL). Here we critically appraise this new surgical advance and discuss other surgical options suggested to offer improvements over current best practice.
