DEN OPEN 2024; 4:e364. [PMID: 38601270 PMCID: PMC11004545 DOI: 10.1002/deo2.364] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/25/2023] [Revised: 03/23/2024] [Accepted: 03/31/2024] [Indexed: 04/12/2024]
Abstract
We describe the case of a 66-year-old man with an anastomotic fistula after rectal surgery, which was treated colonoscopically using polyglycolic acid sheets and fibrin glue. Polyglycolic acid sheets and fibrin glue have been used in thoracic surgery and otolaryngology to reinforce sutures and prevent air leakage. There have been recent reports of their use in endoscopic surgery for the closure of intraoperative perforations after endoscopic submucosal dissection and for fistula closure after upper gastrointestinal tract surgery. However, anastomotic fistulas in colorectal surgery are difficult to visualize endoscopically and may be difficult to suture with clips due to fibrosis. Polyglycolic acid sheets can be easily trimmed, and the fistula can be easily filled using these sheets; moreover, using fibrin glue to fix the sheets may enable fistula closure in areas that are difficult to visualize endoscopically.

Abstract
Exposed endoscopic full-thickness resection (EFTR) without laparoscopic assistance is a minimally invasive natural orifice transluminal endoscopic surgery technique that is emerging as a promising effective and safe alternative to surgery for the treatment of muscularis propria-originating gastric submucosal tumors. To date, various techniques have been used for the closure of the transmural post-EFTR defect, mainly consisting in clip- and endoloop-assisted closure methods. However, the recent advent of dedicated tools capable of providing full-thickness defect suture could further improve the efficacy and safety of the exposed EFTR procedure. The aim of our review was to evaluate the efficacy and safety of the different closure methods adopted in gastric-exposed EFTR without laparoscopic assistance, also considering the recent advent of flexible endoscopic suturing.

Abstract
INTRODUCTION Anastomotic leak after colorectal surgery is a major problem associated with higher morbidity and mortality. In most cases of contained leaks, treatment recommendations are clear and effective. However, in rare cases like necrotizing pelvic infection, there is no clear treatment of choice, despite the mortality rate almost 21%. We present successful management with endoscopic vacuum-assisted closure therapy. THE PRESENTATION OF A CASE A 68-year-old female patient with BMI 26, hypothyroidism and high blood pressure was indicated to low anterior rectal resection because of high-risk neoplasia of lateral spreading tumor type of the upper rectum. Four days after the primary operation, sepsis (SOFA 12) with diffuse peritonitis and unconfirmed leak according to CT led to surgical revision with loop ileostomy. On postoperative days 6-10, swelling, inflammation and subsequent necrosis of the right groin and femoral region communicating with the leak cavity developed. The endoscopy confirmed a leak of 30% of the anastomotic circumference with the indication of debridement and endoscopic vacuum-assisted closure therapy. EVAC sessions with 3-4 day intervals healed the leak cavity. Secondary healing of the skin defects required 4 months. CONCLUSION Necrotizing pelvic infection after a leak of the colorectal anastomosis is a very rare complication with high morbidity and mortality. Endoscopic vacuum-assisted closure therapy should be implemented in the multimodal therapeutic strategy in case of major leaks, affecting up to 270° of the anastomotic circumference.

Abstract
Colon perforations are difficult to resolve because they occur unexpectedly and infrequently. If the clinician is unprepared or lacks training in dealing with perforations, the clinical prognosis will be affected, which can lead to legal issues. We describe here the proper approach to the management of perforations, including deciding on endoscopic or surgical treatment, selection of endoscopic devices, endoscopic closure procedures, and general management of perforations that occur during diagnostic or therapeutic colonoscopy.

Abstract
Submucosal tumors (SMT) are protuberant lesions with intact mucosa that have a wide differential. These lesions may be removed by standard polypectomy, endoscopic mucosal resection (EMR), endoscopic submucosal dissection (ESD), or surgically. However, in lesions that arise from the muscularis propria, full thickness resection is recommended. This can be completed using either endoscopic full thickness resection (EFTR) or submucosal tunneling endoscopic resection (STER). EFTR can be accomplished by completing a full thickness resection followed by defect closure or by securing gastrointestinal wall patency before resection. STER is an option that first creates a mucosal dissection proximal to the lesion to allow a submucosal tunnel to be created. Using this tunnel, the lesion may be resected. When comparing STER to EFTR, there was no significant difference when evaluating tumor size, operation time, rate of complications, or en bloc resection rate. However, suture time, amount of clips used, and overall hospital stay were decreased in STER. With these differences, EFTR may be more efficacious in certain parts of the gastrointestinal tract where a submucosal tunnel is harder to accomplish.

Abstract
Background and aims: The aim of this study was to compare and analyze the feasibility and safety of two methods of endoscopic full-thickness resection (EFTR) for the management of challenging epithelial and subepithelial neoplasms that are not amenable to resection techniques.Material and methods: This was a retrospective case series study of patients who underwent one of two methods of EFTR, resection using ESD knives and post-resection closure with OTSC (Group 1), or closure with OTSC and secondary EFTR with snare (Group 2).Results: Of 11 patients, six were in Group 1 and five in Group 2. The mean time of the EFTR procedure was 76.83 ± 34.97 min in Group 1 which is significantly longer than that of Group 2 (p = .0128). The mean time of OSTC closure and length of hospital stay of Group 1 were also longer compared to Group 2, but the difference was not significant. Complete resection (R0) and technical success rates of Group 1 and Group 2 were 83.3% and 100% (p = .338), respectively. VAS scores of Group 1 immediately after the operation and after 24 h are significantly higher than those of Group 2 (p = .047 and p = .009, respectively). In Group 1, one patient had delayed perforation which led to fever and pneumoperitoneum, and one patient developed abdominal pain. No complications associated with the endoscopic procedure were observed in Group 2.Conclusion: EFTR of pre-resection closure are potentially faster compared with the concept of applying closure after EFTR. Larger prospective controlled studies comparing these two techniques are warranted in the future.

Abstract
Bariatric surgery has rapidly emerged as a modality for managing morbid obesity; however, despite being considered safe, some complications do exist. Formation of a gastrobronchial fistula is a rare complication of laparoscopic sleeve gastrectomy that is associated with high morbidity and mortality. Nowadays, novel endoscopic techniques have widely been adopted in the management of such cases, as they provide minimally invasive options that decrease the morbidity and mortality. Here, the author presents a report of a middle-aged, morbidly obese male who had previously undergone laparoscopic sleeve gastrectomy and returned with a 3-month history of productive cough. On upper gastrointestinal series, the patient was found to have a fistula communicating the stomach to the bronchial tree of his left lung (gastrobronchial fistula). He was treated with endoscopic fistula closure using an over-the-scope clip and a fully-covered Niti-S metallic stent. After this treatment, the patient's symptoms improved dramatically, and the stent was successfully removed 12 weeks later. This report highlights the management of a patient with gastrobronchial fistula formation following laparoscopic sleeve gastrectomy as well as provides a literature review of using combined endoscopic management to treat gastrobronchial fistulas.

Abstract
AIM To investigate the effectiveness of over-the-scope-clip (OTSC)-based endoscopic closure in patients with perforated peptic ulcer (PPU). METHODS One hundred six patients diagnosed with PPU were treated with either OTSC (n = 26) or conservative treatments (n = 80), respectively. The outcome assessments included technical success rate, clinical success rate, post-treatment complications after 1 month, mortality rate, time to resume oral feeding, length of hospital stay, and the administration of antibiotics. RESULTS In the OTSC group, technical and clinical success was achieved in 100% of patients without any complications, including death, incomplete closure, duodenal obstruction, and gastrointestinal bleeding, with a median operation time of 10 min. All patients in the OTSC group were discharged, while the mortality rate in the control group was 13.8%. Subsequent surgeries were required in 30% of patients in the control group. The median times to resume oral feeding were 3.5 (interquartile range [IQR] 2.0-5.25) days in the OTSC group and 7.0 (IQR 5.0-9.0) days in the control group (p < 0.001). One month post-procedure, 30% (24/80) of patients in the control group and 0 (0/26) in the OTSC group required additional operations (p < 0.001). No significant difference was found in the length of the hospital stay and the administration of antibiotics between the two groups (p > 0.05). CONCLUSIONS OTSC-based endoscopic technique, with a high clinical success rate and a shorter time to resume oral feeding, was effective in achieving closure of PPU with a diameter < 15 mm.

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
Esophageal perforation is a medical emergency associated with high morbidity and mortality. There is no consensus on the optimal treatment of this life-threatening condition. Conventional treatment of esophageal perforation is surgical. However, more recently, endoscopic treatment has become the treatment of choice given its less invasive nature compared to surgical treatment. This includes endoscopic clip administration, endoscopic stent placement, endoscopic suturing, endoscopic vacuum therapy and tissue sealants which are all administered via the endoluminal route. Whilst small defects (<2 cm) may be closed with endoscopic clips, larger defects require stent placement or suturing. Removable esophageal stent is an effective method of treatment in cases with esophageal perforation as they allow minimal invasive repair of perforation and rapid nutrition. Endoscopic suturing can be used both to fix the stent to prevent migration and to primarily close the perforation. If perforation is associated with a mediastinal collection, drainage is mandatory and this procedure can be performed by computed tomography guided percutaneous drainage, thoracoscopy or endoscopic vacuum therapy. In some cases, a combination of these minimally invasive methods is required. Since endoscopic methods provide better quality of life and outcomes and shorten length of hospitalization, such methods have become the treatment of choice for esophageal perforation.

Abstract
Endoscopic submucosal dissection is established as a curative endoscopic method for gastrointestinal epithelial neoplasms with a high possibility of complete en bloc resection; however, postoperative adverse events of bleeding and delayed perforation remain. To prevent or minimize them, several techniques for endoscopic mucosal closure have been introduced, such as using endoscopic clips, combined use of hemoclips and supplement devices, and specially designed endoscopic suturing devices. Furthermore, endoscopic full-thickness suturing technique for gastrointestinal wall defect has been developed based on the concept in natural orifice transluminal endoscopic surgery and endoscopic full-thickness resection. Several closure techniques, including over-the-scope clip, threaded bars inserted in a hollow needle, stitches or staplers, and a curved needle and thread are reported. Secure closure of the iatrogenic defect may further expand the range of therapeutic endoscopy. Accumulation of evidence for the efficacy of endoscopic closure and establishment of these techniques are desired.

Abstract
BACKGROUND AND STUDY AIMS Classic endoscopic resection techniques (EMR and ESD) are limited to mucosal lesions. In the case of deeper growth into the gut wall and anatomic sites prone to perforation, the novel full-thickness resection device (FTRD®) opens a new dimension of possibilities for endoscopic resection. PATIENTS AND METHODS Sixty patients underwent endoscopic full-thickness resection (eFTR) at our institution. Safety, learning curve, R0 resection rate, and clinical outcome were studied. RESULTS In 97% (58/60) of the interventions, the FTRD®-mounted endoscope reached the previously marked lesion and eFTR was performed (technical success). Full-thickness resection was achieved in 88% of the cases, with an R0 resection on histological examination in 79%. The clinical success rate based on follow-up histology was even higher (88%). Adverse events occurred in 7%. Appendicitis of the residual cecal appendix after eFTR of an adenoma arising in the appendix led to the only post-eFTR surgery (1/58, 2%). Minor bleeding at the eFTR site (2/58, 3%) and an eFTR performed accidently without proper prior deployment of the OTSC® (1/58, 2%) were successfully treated endoscopically. There was no secondary perforation or eFTR-associated mortality. CONCLUSIONS After specific training, eFTR is a feasible, safe, and promising all-in-one endoscopic resection technique. Our data show that eFTR allows complete resection of lesions affecting layers of the gut wall beneath the mucosa with a low risk of adverse events. However, our preliminary results need to be confirmed in larger, controlled studies.

Abstract
There have been considerable advances in the endoscopic treatment of colorectal neoplasia. The development of endoscopic submucosal dissection and full thickness resection techniques is changing the way benign disease and early cancers are managed. This article reviews the evidence behind these new techniques and discusses where this field is likely to move in the future. Areas covered: A PubMed literature review of resection techniques for colonic neoplasia was performed. The clinical and cost effectiveness of endoscopic mucosal resection (EMR) is examined. The development of endoscopic submucosal dissection (ESD) and knife assisted resection is described and issues around training reviewed. Efficacy is compared to both EMR and transanal endoscopic microsurgery. The future is considered, including full thickness resection techniques and robotic endoscopy. Expert commentary: The perceived barriers to ESD are falling, and views that such techniques are only possible in Japan are disappearing. The key barriers to uptake will be training, and the development of educational programmes should be seen as a priority. The debate between TEMS and ESD will continue, but ESD is more flexible and cheaper. This will become less significant as the number of endoscopists trained in ESD grows and some TEMS surgeons may shift across towards ESD.

Abstract
BACKGROUND AND AIMS Closure of gastric wall defects after endoscopic full-thickness resection remains a clinical challenge. We aimed to introduce an endoscopic puncture-suture device (EPSD) for the closure of such defects. We evaluated the safety, efficacy, and outcomes of the EPSD for closure of gastric wall defects after endoscopic full-thickness resection (EFTR), compared with the metallic clips closure method. METHODS Twenty-four Bama mini pigs (20-25 kg) were randomly divided into 2 groups. The EPSD was used in the experimental group and metallic clips were used in the control group. Twelve pigs were randomly assigned to each group. Six pigs underwent EFTR on the anterior wall of the gastric body, whereas the other 6 pigs underwent the same procedure on the posterior wall. The diameter of the resection margin was 2 cm. Either EPSD or metallic clips were applied to close the defects. The duration of the resection and closure, incidence of operative adverse events, and wound recovery were compared and analyzed according to the method of closure. RESULTS For defects at the same sites, EPSD significantly reduced closure time compared with the metallic clips method (anterior wall, 8 min vs 27.5 min; posterior wall, 7.8 min vs 26.8 min). CONCLUSION EPSD is a quick, simple, safe, and effective method to close gastric wall defects after EFTR.

Abstract
Esophageal perforations can be spontaneous or iatrogenic. Although they are a rare occurrence, they are associated with a significant morbidity and mortality. Traditionally, management of esophageal perforation consisted of surgery. However, endoscopic management is now emerging as the primary treatment modality and is less invasive and morbid than surgery. Endoscopic modalities include through-the-scope clips (TTS), over-the-scope clips (OTSC), placement of covered stents, and suturing. Suturing can be used for primary closure of the perforation as well as anchoring of stents to prevent migration. Smaller defects (<2 cm) can be closed with clips (TTS or OTSC), whereas larger defects require a stent placement or suturing to achieve closure. If the perforation is associated with a mediastinal collection, drainage is mandatory and can be done via CT-guided percutaneous drainage, surgery, or endoscopic vacuum therapy.

Abstract
AIM To introduce natural orifice transgastric endoscopic surgery (NOTES) tube ileostomy using pelvis-directed submucosal tunneling endoscopic gastrostomy and endoscopic tube ileostomy.
METHODS Six live pigs (three each in the non-survival and survival groups) were used. A double-channeled therapeutic endoscope was introduced perorally into the stomach. A gastrostomy was made using a 2-cm transversal mucosal incision following the creation of a 5-cm longitudinal pelvis-directed submucosal tunnel. The pneumoperitoneum was established via the endoscope. In the initial three operations of the series, a laparoscope was transumbilically inserted for guiding the tunnel direction, intraperitoneal spatial orientation and distal ileum identification. Endoscopic tube ileostomy was conducted by adopting an introducer method and using a Percutaneous Endoscopic Gastrostomy Catheter Kit equipped with the Loop Fixture. The distal tip of the 15 Fr catheter was placed toward the proximal limb of the ileum to optimize intestinal content drainage. Finally, the tunnel entrance of the gastrostomy was closed using nylon endoloops with the aid of a twin grasper. The gross and histopathological integrity of gastrostomy closure and the abdominal wall-ileum stoma tract formation were assessed 1 wk after the operation.
RESULTS Transgastric endoscopic tube ileostomy was successful in all six pigs, without major bleeding. The mean operating time was 71 min (range: 60-110 min). There were no intraoperative complications or hemodynamic instability. The post-mortem, which was conducted 1-wk postoperatively, showed complete healing of the gastrostomy and adequate stoma tract formation of ileostomy.
CONCLUSION Transgastric endoscopic tube ileostomy is technically feasible and reproducible in an animal model, and this technique is worthy of further improvement.

Abstract
Anastomotic leakage is an unfortunate complication of colorectal surgery. This distressing situation can cause severe morbidity and significantly affects the patient’s quality of life. Additional interventions may cause further morbidity and mortality. Parenteral nutrition and temporary diverting ostomy are the standard treatments of anastomotic leaks. However, technological developments in minimally invasive treatment modalities for anastomotic dehiscence have caused them to be used widely. These modalities include laparoscopic repair, endoscopic self-expandable metallic stents, endoscopic clips, over the scope clips, endoanal repair and endoanal sponges. The review aimed to provide an overview of the current knowledge on the minimally invasive management of anastomotic leaks.

Abstract
BACKGROUND Gastrogastric fistulae (GGF) are a well-known complication of Roux-en-Y gastric bypass (RYGB). Endoscopic approaches for closure of GGF have gained popularity, but with limited data and efficacy. OBJECTIVES The primary arm of the study was to evaluate the safety and efficacy of the endoscopic closure of GGF using the over-the-scope clip (OTSC) device. SETTING University hospital, United States METHODS: This is a retrospective review of consecutive patients at a single academic center from September 2013 to December 2014 who underwent upper endoscopy with attempted OTSC placement for closure of GGF related to RYGB. Preprocedural, procedural, and postprocedural data were collected. Outcome measures included technical success, primary success, and long-term success. RESULTS A total of 14 patients underwent attempted GGF closure using OTSC. Twelve of the 14 patients (85.7%) had technical success. Four patients were lost to follow-up. Primary success was achieved in 5 of the 10 patients (50%) in which it was assessed, either by upper gastrointestinal series or endoscopy. One of the 5 patients who had primary success was then lost to follow-up. Of the 4 patients in whom primary success was achieved and had long-term follow up, 75% (n = 3) achieved long-term success at a mean follow-up of 6.6 months from initial OTSC placement (range, 3-9), making for a long-term success rate of 33% (3/9). There were no reported complications. CONCLUSION OTSC closure of small GGF is feasible, safe, and offers a reasonable alternative to surgical revision. Large GGF may undergo attempted endoscopic closure, acknowledging a high failure rate.

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
Aim. To study the efficacy and other treatment outcomes of Ovesco clip closure of iatrogenic perforation. Methods. Retrospective study from 3 tertiary-care hospitals in Thailand. Patients with iatrogenic perforation who underwent immediate endoscopic closure by Ovesco clip were included. Patients' demographic data, perforation size, number of Ovesco clips used, fasting day, length of hospital stay, success rates, and complication rate were recorded. Technical success was defined as closure achievement during endoscopic procedure and clinical success was defined as the patient can be discharged without the need of additional surgical or radiological intervention. Results. There were 6 iatrogenic perforations in 2 male and 4 female patients. The median age was 59 years (range 39-78 years). The locations of perforation were 5 duodenal walls and 1 rectosigmoid junction. The median perforation size was 13 mm (range 10-40 mm). The technical success was 100% and the clinical success was 83.3%. The success rates per locations were 100% in colon and 80% in duodenum, respectively. The median fasting time was 5 days (range 1-10 days) and the median length of hospital stay was 10 days (range 2-22 days). There was no mortality in any. Conclusion. Ovesco clip seems to be an effective and safe tool for a closure of iatrogenic perforation.

Abstract
BACKGROUND Iatrogenic gastrointestinal perforation is a life-threatening complication that arises very rarely in routine endoscopic procedures, with an incidence of 0.03-0.8%. It is more likely in highly complex and invasive therapeutic interventions. In certain situations, endoscopic closure of the perforation and treatment with antibiotics can obviate the need for emergency surgical repair. METHODS This review is based on pertinent articles retrieved by a selective literature search in PubMed and on a relevant position paper. RESULTS Existing clinical studies of treatment for iatrogenic gastrointestinal perforation are mainly retrospective and uncontrolled. No randomized and controlled trials have been performed to date. If the perforation is discovered soon after it arises, endoscopic treatment can be considered. Gastrointestinal perforations that are less than 30 mm in size can be closed with a clip. In the esophagus, expanding metal stents can be used as well. Clip application is successful in 80-100% of cases of gastrointestinal perforation, and the perforation remains permanently closed in 60-100% of cases. Reports on the endoscopic treatment of esophageal perforation show mixed results, with closure rates of roughly 90% and clinical success rates of roughly 80%. If endoscopic treatment is not possible, timely laparoscopic or open surgical repair is needed. CONCLUSION The endoscopic treatment of iatrogenic perforations is safe and reliable. Success depends on early detection, adequate endoscopic closure with properly mastered technique, and the early initiation of concomitant antibiotic treatment, which must be continued for a full course. Most patients who are treated in this way do not need emergency surgery.

Abstract
AIM: To investigate the efficacy and clinical outcome of patients treated with an over-the-scope-clip (OTSC) system for severe gastrointestinal hemorrhage, perforations and fistulas.
METHODS: From 02-2009 to 10-2012, 84 patients were treated with 101 OTSC clips. 41 patients (48.8%) presented with severe upper-gastrointestinal (GI) bleeding, 3 (3.6%) patients with lower-GI bleeding, 7 patients (8.3%) underwent perforation closure, 18 patients (21.4%) had prevention of secondary perforation, 12 patients (14.3%) had control of secondary bleeding after endoscopic mucosal resection or endoscopic submucosal dissection (ESD) and 3 patients (3.6%) had an intervention on a chronic fistula.
RESULTS: In 78/84 patients (92.8%), primary treatment with the OTSC was technically successful. Clinical primary success was achieved in 75/84 patients (89.28%). The overall mortality in the study patients was 11/84 (13.1%) and was seen in patients with life threatning upper GI hemorrhage. There was no mortality in any other treatment group. In detail OTSC application lead to a clinical success in 35/41 (85.36%) patients with upper GI bleeding and in 3/3 patients with lower GI bleeding. Technical success of perforation closure was 100% while clinical success was seen in 4/7 cases (57.14%) due to attendant circumstances unrelated to the OTSC. Technical and clinic success was achieved in 18/18 (100%) patients for the prevention of bleeding or perforation after endoscopic mucosal resection and ESD and in 3/3 cases of fistula closure. Two application-related complications were seen (2%).
CONCLUSION: This largest single center experience published so far confirms the value of the OTSC for GI emergencies and complications. Further clinical experience will help to identify optimal indications for its targeted and prophylactic use.

Abstract
Luminal perforations and anastomotic leaks of the gastrointestinal tract are life-threatening events with high morbidity and mortality. Early recognition and prompt therapy is essential for a favourable outcome. Surgery has long been considered the "gold standard" approach for these conditions; however it is associated with high re-intervention morbidity and mortality. The recent development of endoscopic techniques and devices to manage perforations, leaks and fistulae has made non-surgical treatment an attractive and reasonable alternative approach. Although endoscopic therapy is widely accepted, comparative data of the different techniques are still lacking. In this review we describe, benefits and limitations of the current options in the management of patients with perforations and leaks, in order to improve outcomes.

Abstract
The adoption of endoscopic surgery continues to expand in clinical situations with the recent natural orifice transluminal endoscopic surgery technique enabling abdominal organ resection to be performed without necessitating any skin incision. In recent years, the development of numerous devices and platforms have allowed for such procedures to be carried out in a safer and more efficient manner, and in some ways to better simulate triangulation and surgical tasks (e.g., suturing and dissection). Furthermore, new novel techniques such as submucosal tunneling, endoscopic full-thickness resection and hybrid endo-laparoscopic approaches have further widened its use in more advanced diseases.

Abstract
BACKGROUND AND AIMS Endoscopic resection of duodenal non-lifting adenomas and subepithelial tumors is challenging and harbors a significant risk of adverse events. We report on a novel technique for duodenal endoscopic full-thickness resection (EFTR) by using an over-the-scope device. METHODS Data of 4 consecutive patients who underwent duodenal EFTR were analyzed retrospectively. Main outcome measures were technical success, R0 resection, histologic confirmation of full-thickness resection, and adverse events. Resections were done with a novel, over-the-scope device (full-thickness resection device, FTRD). RESULTS Four patients (median age 60 years) with non-lifting adenomas (2 patients) or subepithelial tumors (2 patients) underwent EFTR in the duodenum. All lesions could be resected successfully. Mean procedure time was 67.5 minutes (range 50-85 minutes). Minor bleeding was observed in 2 cases; blood transfusions were not required. There was no immediate or delayed perforation. Mean diameter of the resection specimen was 28.3 mm (range 22-40 mm). Histology confirmed complete (R0) full-thickness resection in 3 of 4 cases. To date, 2-month endoscopic follow-up has been obtained in 3 patients. In all cases, the over-the-scope clip was still in place and could be removed without adverse events; recurrences were not observed. CONCLUSIONS EFTR in the duodenum with the FTRD is a promising technique that has the potential to spare surgical resections. Modifications of the device should be made to facilitate introduction by mouth. Prospective studies are needed to further evaluate efficacy and safety for duodenal resections.

Abstract
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 Endoscopic full-thickness resection (EFTR) is a mini-invasive technique for gastric subepithelial tumors originating from the muscularis propria, which enables a full-thickness resection of tumors and can provide a complete basis for pathological diagnosis. Gastric fistula closure after EFTR is a challenge for endoscopists. In this study, we introduced EFTR with fistula closure using the over-the-scope clip (OTSC) system for gastric subepithelial tumors originating from the muscularis propria. Objectives To evaluate the feasibility and safety of fistula closure with OTSC by a retrospective analysis on the cases of EFTR with defect closure using OTSC for gastric subepithelial tumors originating from the muscularis propria in our hospital. Methods The patients were selected who underwent EFTR for gastric subepithelial tumors originating from the muscularis propria (tumor diameter ≤2 cm) in our hospital from October 2013 to March 2014. After a full-thickness resection of tumors, the bilateral gastric mucous membranes of defect were clamped using twin graspers and then drawn into the transparent cap of OTSC, and the OTSC was released to close the defect after full suctioning. The success rate of defect closure with OTSC was observed, and the endoscopic follow-up was performed at 1 week, 1 and 6 months after operation to check OTSC closure. Results Totally 23 patients were included into the study. The full-thickness resection rate of gastric tumors in the muscularis propria was 100 % (23/23), the success rate of defect closure was 100 %, and the average time of defect closure was 4.9 min (range 2–12 min). All patients experienced no postoperative complications such as bleeding and perforation. The postoperative follow-up time was 1–6 months (mean 3 months), and no OTSC detachment was found. Conclusions OTSC can be used to perform EFTR with defect closure for gastric tumors in the muscularis propria (tumor diameter ≤2 cm). It is simple, convenient, safe and effective.

Abstract
With our case we have adopted an innovative approach of using endolooping for an early perforation that was within a short distance of the appendicular base, applied proximal to the site of the perforation. In our surgery, the area of ischemic injury can be easily visualized through the laparoscopy and including fresh and healthy tissue margins in the loop is the hallmark of safety for this simple technique. The endoloop technique described, undertaken during a laparoscopy is a novel approach. It is a simple and effective method, reminding clinicians to adapt techniques when necessary. Nevertheless, it is only limited to perforations around the appendicular base. The endolooping technique may not be suitable for late presentation, large perforations with ischemic or friable tissue, and severe peritonitis. In such cases, the use of other methods, such as wedge resection or stapling would be safer.
Introduction An iatrogenic caecal perforation is rare, but a serious complication associated with significant morbidity and mortality. We present a 4 min and 50 s video on a new improvisation undertaken during laparoscopic management of post-polypectomy caecal perforation. Presentation of case Our patient presented with an acute abdomen following endoscopic polypectomy. At surgery, the site of caecal perforation was close to the appendicular base with devitalization tissue, secondary to diathermy usage. The hallmark of safety within this novel technique included fresh healthy tissue margins within the endoloop (detachable snare ligation) and ensuring no ischemic tissue was gathered. Complete freeing of the appendix and meso-appendicular base was required and securing three endoloops proximal to the site of perforation. The post-operative course was uneventful. Discussion The World Society of Emergency Surgery (WSES) 2013 guidelines suggested an early laparoscopic approach is a safe and effective treatment for colonoscopy-related colonic perforation. There are no national guidelines and the management is dictated by the clinical condition of the patient, co-morbidity, size and site of perforation as well as the scale of bowel preparation, and surgical experience. Conclusion The endoloop technique described, undertaken during a laparoscopy is a novel approach. It is a simple and effective method, reminding clinicians to adapt techniques when necessary. Nevertheless, it is only limited to perforations around the appendicular base.

Current innovations in endoscopic therapy for the management of colorectal cancer: from endoscopic submucosal dissection to endoscopic full-thickness resection. BIOMED RESEARCH INTERNATIONAL 2014; 2014:925058. [PMID: 24877148 PMCID: PMC4022075 DOI: 10.1155/2014/925058] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/30/2014] [Revised: 04/11/2014] [Accepted: 04/14/2014] [Indexed: 12/11/2022]
Abstract
Endoscopic submucosal dissection (ESD) is accepted as a minimally invasive treatment for colorectal cancer. However, due to technical difficulties and an increased rate of complications, ESD is not widely used in the colorectum. In some cases, endoscopic treatment alone is insufficient for disease control, and laparoscopic surgery is required. The combination of laparoscopic surgery and endoscopic resection represents a new frontier in cancer treatment. Recent developments in advanced polypectomy and minimally invasive surgical techniques will enable surgeons and endoscopists to challenge current practice in colorectal cancer treatment. Endoscopic full-thickness resection (EFTR) of the colon offers the potential to decrease the postoperative morbidity and mortality associated with segmental colectomy while enhancing the diagnostic yield compared to current endoscopic techniques. However, closure is necessary after EFTR and natural transluminal endoscopic surgery (NOTES). Innovative methods and new devices for EFTR and suturing are being developed and may potentially change traditional paradigms to achieve minimally invasive surgery for colorectal cancer. The present paper aims to discuss the complementary role of ESD and the future development of EFTR. We focus on the possibility of achieving EFTR using the ESD method and closing devices.

Abstract
BACKGROUND AND AIMS This retrospective study evaluated the safety and efficacy of endoscopic full-thickness resection (eFTR) with defect closure using clips and an endoloop for the treatment of gastric subepithelial tumors (SETs) arising from the muscularis propria (MP). METHODS From January 2009 to December 2012, 51 patients with gastric SETs arising from the MP underwent eFTR with defect closure using clips and an endoloop. The key steps were (1) several milliliters of mixture solution was injected into the submucosa after dots were marked around the tumor; (2) a cross incision was made in the mucosa to reveal the tumor; (3) subsequently, circumferential excavation was performed as deep as the muscularis propria, and full-thickness resection of the tumor was performed with an insulated-tip knife, including its underlying MP and serosa; (4) the gastric wall defect was closed with clips and an endoloop was then placed to fix and tighten all of the clips together. RESULTS Successful complete resection by eFTR was achieved in 50 cases (98.0%). One case failed and was converted into a laparoscopic resection due to the tumor falling into the peritoneal cavity during the procedure. The mean procedure time was 52 min. No patients had severe complications, such as massive bleeding, delayed bleeding, peritonitis, or gastrointestinal tract leakage. The mean tumor length was 2.4 cm. Pathological diagnoses of the tumors were leiomyomas (21/51) and gastrointestinal stromal tumors (30/51). The median follow-up period after the procedure was 22.4 months (range 1-48 months), and no residual tumor or tumor recurrence was detected during the follow-up period. CONCLUSIONS eFTR with defect closure with clips and an endoloop appears to be a safe and effective technique for the treatment of patients with gastric SETs originating from the MP, especially for those with extraluminal growth or adhesions to the MP.

Abstract
BACKGROUND This study retrospectively reviewed 48 cases of gastric submucosal tumors (SMTs) treated by endolumenal endoscopic full-thickness resection (EFR) microsurgery in our gastrointestinal endoscopy center. PATIENTS AND METHODS From November 2009 to October 2012, 48 cases underwent endolumenal EFR for resection of muscularis propria-originating gastric SMTs. Characteristics of the 48 patients, clinical efficacy, safety of EFR, and post-EFR pathological diagnoses were evaluated retrospectively. RESULTS EFR was successfully performed in 48 cases with 52 lesions. The median operation time was 59.72 minutes (range, 30-270 minutes; standard deviation, 39.72 minutes). The mean tumor size was 1.59 cm (range, 0.50-4.80 cm; standard deviation, 1.01 cm). During the EFR process, dual-channel gastroscopy was applied in 20 cases of SMTs, and paracentesis during the EFR process was applied in 9 cases. EFR for larger SMTs and gastric corpus-originating SMTs had longer operative times. Pathological diagnosis included 43 gastrointestinal stromal tumors, 4 leiomyomas, and 1 schwannoma. A larger tumor size was associated with higher risk of malignancy. No severe postoperative complications were observed. No tumor recurrences were confirmed in follow-up gastroscopy. CONCLUSIONS The endolumenal EFR technique proved to be feasible and minimally invasive, even for the resection of large gastric tumors originating from the muscularis propria. However, more data on EFR must be obtained and analyzed.

Abstract
BACKGROUND Gastric submucosal tumors (SMTs) originating from the muscularis propria layer are treated endoscopically. Successful closure of the wall defect is a critical step. This study evaluated the safety and feasibility of the endoscopic purse-string suture (EPSS) method using an endoloop and several metallic clips after endoscopic full-thickness resection (EFTR) or perforation due to endoscopic submucosal dissection (ESD). METHODS From December 2009 to April 2013, 30 patients with SMTs originating from the muscularis propria layer who received EFTR or ESD were retrospectively analyzed. After successful tumor resection, an endoloop was anchored onto the circumferential margin of the gastric defect with several metallic clips and tightened gently. Patient characteristics, tumor size, en bloc resection, and postoperative complications were evaluated. RESULTS For all 30 patients, EPSS was successfully performed after EFTR or perforation due to ESD. The mean diameter of the resected specimen was 1.9 cm. No severe complications occurred during or after the procedure. The lesions were healed 1 month after the procedure, as confirmed endoscopically. CONCLUSION The EPSS method using an endoloop and clips is an effective and safe technique for closing the gastric defect after EFTR or perforation due to ESD.

Abstract
Abstract
Background
Patients requiring surgery for complex colonic polyps traditionally undergo colectomy, with significant risks. Typically in excess of 10–30 cm of colon is removed at laparoscopic or open surgery lasting over 60 min. This study details the preclinical development of a rapid, minimally invasive, limited full-thickness colonic resection.
Methods
Both survival and non-survival procedures were performed in anaesthetized 70-kg pigs. A simulated colonic polyp was created by endoscopic ink injection with a clearance margin delineated by circumferential placement of mucosal argon plasma coagulation marks. Full-thickness eversion of the bowel was achieved using endoscopically placed anchors and the polyp was excised using a laparoscopic stapler. In survival procedures, pigs were killed under anaesthetic 8 days after surgery. All pigs underwent post-mortem examination.
Results
Five procedures were performed (5 pigs). The median (range) procedure duration was 26 (20–31) min, with a specimen diameter of 5·1 (4·5–6·3) cm. The postoperative recovery of survival animals (4 pigs) was uneventful. At post-mortem evaluation the resection sites were well healed with no evidence of stenosis, intra-abdominal infection or inadvertent organ damage. Histological assessment of anastomoses showed mucosal repair and restoration of submucosal continuity.
Conclusion
Full-thickness localized colonic excision with this technique provides a large specimen with adequate healing in a porcine model.

Abstract
BACKGROUND AND AIM To evaluate the effectiveness and outcomes of endoscopic closure of a gastric fundus perforation using over-the-scope clips (OTSCs) system in a surviving canine model. METHODS Gastric fundus perforations (20-mm diameter) were created by an endoscopic needle-knife in six dogs. The perforations then were closed by the OTSC system. Gastroscopy was performed to evaluate the postoperative perforation healing every week. The animals were sacrificed 4 weeks later to examine the possible intraperitoneal complications, and the healing of the perforation was examined histopathologically. RESULTS The gastric fundus perforations could primarily be closed using one OTSC in each experimental dog, and the mean time of the procedure was 17.3 ± 7.6 min (9-26 min). All animals survived without postoperative complications. The OTSC retention was observed in one dog at the end of 4 weeks, and the apparent foreign-body reaction was examined pathologically. CONCLUSIONS Our surviving animal study demonstrated that the OTSC clip system could reliably close gastric fundus perforations without complications.

Abstract
Background. OTSCs are now available in the US for various indications. Methods. Retrospective review of OTSCs used from January 2011 to April 2012. Results. Twenty-four patients underwent placement of 28 OTSCs. Indications included postsurgical fistula, perforations, anastomotic leak, prophylactic closure after EMR, postpolypectomy bleeding, tracheoesophageal fistula, and jejunostomy site leak. Instruments used to grasp the tissue were dedicated (bidirectional forceps or tripronged device) and nondedicated devices (rat/alligator forceps or suction). Success was higher with nondedicated devices (12.5% versus 86.5%, P = 0.0004). Overall, OTSC was effective in 15/27 procedures. Defect closure was complete in 12/21. Mean followup was 2.9 months (1–8 m). Mean defect size was 10 mm (5–25 mm). A trend towards higher success was noted in defects <10 mm compared to defects >10 mm (90% versus 60%; P = 0.36). No difference was noted in closure of fresh (<72 hrs) versus chronic defects (>1 month) (75% versus 67%). There were no complications. Conclusion. The OTSC provides a safe alternative to manage fistula, perforation, and bleeding. No significant difference was seen for closure of early fistula or perforations as compared to chronic fistula. Rat-tooth forceps or suction was superior to the dedicated devices.

Abstract
PURPOSE This review summarizes the published methods of colonic EFTR, examining data on feasibility and safety. Due to the introduction of bowel cancer screening programs, there is an increasing incidence of complex colonic polyps and early colonic cancer that requires segmental colectomy. Traditional radical surgery is associated with significant morbidity, and there is a need for alternative treatments. METHODS Systematic literature search identified articles describing EFTR techniques of colon, published between 1990 and 2012. Complication rates, anastomotic bursting pressures, procedure duration, specimen size and quality, and postmortem findings were analyzed. RESULTS Five research groups reported four EFTR techniques using endoscopic stapling devices, T-tags, compression closure, or laparoscopic assistance for defect closure before or after specimen resection. A total of 113 procedures were performed in 99 porcine models, with an overall success rate of 89 and 4 % mortality. The intraoperative complication rate was 22 % (0-67 %). Post-resection closure methods more commonly resulted in failure to close the defect (5-55 %) and a high incidence of abnormal findings at postmortem examination (84 %). Significant heterogeneity was observed in procedure duration (median or mean 3-233 min) and size of the excised specimen (median or mean 1.7-3.6 cm). Anastomotic bursting pressures and specimen quality were poorly documented. CONCLUSIONS The technique of EFTR is developing, but the inability to close the resection defect reliably is a major obstacle. The review highlights the challenges that need to be addressed in future preclinical studies.

Abstract
BACKGROUND Many GI motility disorders are associated with underlying GI neuromuscular pathology, which requires full-thickness biopsies (FTB) for histopathologic diagnosis. Currently, none of the endoscopy-based attempts to obtain FTB specimens have proven suitable for routine use. This study evaluated a novel endoscopic prototype device (ED) for this purpose. OBJECTIVE To determine (1) the ability of the ED to obtain suitable FTB specimens, (2) associated complications, (3) feasibility of reliable defect closure, and (4) ability to evaluate intramural neuromuscular components. DESIGN Preclinical proof-of-concept study in 30 pigs. SETTING Animal laboratory. INTERVENTION Gastric FTB specimens were obtained with a circular cutter and anchor. The defect was closed by over-the-scope clips/T-tags. The resection site was inspected via laparoscopy. After 2 to 4 weeks, necropsy was carried out to evaluate late complications. MAIN OUTCOME MEASUREMENTS Feasibility, safety, and closure rate of the procedure. FTB specimens were assessed by histology/immunohistochemistry to visualize enteric neuromusculature. RESULTS A total of 29 of 30 procedures were successfully performed; one hemorrhage required endoscopic treatment. A total of 29 of 30 FTB specimens (mean diameter 9.1 mm) were retrieved in 7.1 ± 0.4 minutes (range 3.0-12.5 minutes), displaying optimal tissue quality. Defect closure took 10.8 ± 0.9 minutes (range 7.2-32 minutes). Laparoscopy did not reveal damage to adjacent organs. Necropsy showed well-healed scars at the resection site and no complications, peritonitis, or abscess formation. Histology showed smooth muscle layers and submucosal and myenteric ganglia. LIMITATIONS Survival animal pilot study, no patients. CONCLUSION The novel ED enabled safe harvesting of well-preserved FTB specimens. Defect closure proved to be reliable. All neuromuscular structures relevant for histopathologic evaluation of GI neuromuscular pathology were demonstrated. Further studies are needed to verify the efficacy of this prototype device in the entire gut and in humans.
