Endoscopic Management of Surgical Complications: Tools and Techniques

Endoscopic Suturing for Defect Closure

• 🧵 The Overstitch device is a key tool for full-thickness defect closure, evolving from earlier models to work on single-channel scopes.
• 💡 It's particularly useful for planned procedures like endoscopic sleeve gastroplasty and for closing iatrogenic perforations with fresh tissue.
• 🏥 While effective, the cost-effectiveness of Overstitch compared to clips depends on the number of clips needed, often becoming more economical for larger defects.
• ✅ Clinical success with endoscopic suturing is highly dependent on the indication, with less success in chronic fistulas but excellent results for stent fixation.

Clips and Stent Placement for Complications

• 📌 Hemostatic clips are effective for superficial mucosal tears, stopping bleeding, or closing small mucosies, while newer devices like the Mantis clip show promise for more significant closures.
• 🏥 Internal drainage using double pigtail drains is a preferred method for managing contained abscesses, such as those from sleeve gastrectomy leaks, allowing for gradual healing.
• 🗜️ Esophageal stents, particularly fully covered ones, are used for complications like leaks and strictures, with careful consideration for placement to avoid migration and obstruction.
• ⚠️ Stent migration is a significant concern, with techniques like using Overstitch sutures to fixate stents being employed to prevent complications.

Endovac Therapy for Contaminated Defects

• 🧽 EndoVac therapy involves placing a sponge on an NG tube into a contaminated cavity or defect to provide source control, especially for aortic leaks and perforations.
• ⏳ This is a temporizing measure that aids in wound healing and granulation, requiring commitment and multiple changes over weeks to months.
• 🏥 It's crucial to ensure adequate feeding access and consider potential discomfort for the patient during prolonged Endovvac therapy.

Case Studies and Practical Applications

• 🏥 A case of an esophageal perforation post-esophagectomy was managed with a combination of endoscopic mucosal closure and thoracic surgery intervention, leading to a good outcome.
• 🩹 A complex case of a sleeve gastrectomy stricture involved multiple interventions including stenting, PEG tube placement, and eventual stent removal, highlighting the challenges of managing GI tract breakdowns.
• 🎯 Management of a post-EMR perforation involved assessing the defect size, with options ranging from over-the-scope clips for smaller defects to endoscopic suturing for larger ones, followed by observation.
• 💡 The discussion emphasizes that endoscopic solutions can often mitigate the need for more invasive surgery, offering versatile tools for managing a range of complications.
