POP is a safe and feasible endoscopic intervention for medical refractory gastroparesis. Additional follow-up is required to determine the long-term success of this approach in alleviating gastroparesis symptoms.

Per-oral endoscopic pyloromyotomy (POP) is safe and effective for the treatment of medical refractory gastroparesis. POP has less perioperative morbidity compared to LP with comparative functional outcomes.

Duodenojejunostomy is the most common surgical intervention in management of SMAS. Our intermediate follow-up reveals infrequent improvement and rare resolution of preoperative symptomatology. Patients had a modest average weight gain postoperatively. This may suggest that different preoperative workup and treatment is indicated.

SMAS should be considered a potential diagnosis in patients who present with a history of persistent postprandial vomiting, epigastric pain, and weight loss and confirmatory radiographic findings. In well-selected patients, minimally invasive duodenojejunostomy is a safe and effective treatment for SMAS with excellent short-term outcomes.

All patients with meniscal repair required MR arthrography. All patients with meniscal resection of more than 25%, who did not have severe degenerative arthrosis, chondral injuries, or avascular necrosis required MR arthrography. Patients with less than 25% meniscal resection did not need MR arthrography.

Understanding the technical constructs of bariatric surgery is important to the treating endoscopist to maximize effective endoluminal therapy. Post-operative complication rates vary widely based on the complication of interest, and have been reported to be as high as 68% following adjustable gastric banding. Similarly, there is a wide range of presenting symptoms for post-operative bariatric complications, including abdominal pain, nausea and vomiting, dysphagia, gastrointestinal hemorrhage, and weight regain, all of which may provoke an endoscopic assessment. Bleeding and anastomotic leak are considered to be early (< 30 d) complications, whereas strictures, marginal ulcers, band erosions, and weight loss failure or weight recidivism are typically considered late (> 30 d) complications. Treatment of complications in the immediate post-operative period may require unique considerations. Endoluminal therapies serve as adjuncts to surgical and radiographic procedures. This review aims to summarize the spectrum and efficacy of endoscopic management of post-operative bariatric complications.

Conversion of SG to RYGB is safe and technically feasible when performed for complications of SG or to enhance weight loss. This operation can be successfully performed laparoscopically with a low rate of conversion and reasonable complication profile.

In patients with surgically altered foregut anatomy, DPEJ offers a less invasive alternative to operative jejunostomy tube placement. DPEJ can be placed in the endoscopy suite or operating room with an acceptable risk of perioperative complications.
