Summary: Endoscopic necrosectomy using LAMS is effective for treating complicated WOPN, but more than a third of patients may require necrosectomy. The percentage of necrosis in the collection detected in the CT scan appears to predict the need for necrosectomy.

Summary: This study found that half of patients with pancreatic fluid collections drained with lumen-apposing metal stents required step-up therapy, most commonly direct endoscopic necrosectomy. Patients with larger collections, paracolic extension, or higher solid necrosis content were more likely to need step-up therapy.

Summary: The study compared outcomes of different approaches for managing pancreatic fluid collections (PFCs) and found that an integrated approach using LAMS with selective use of plastic stents significantly improved treatment success compared to using only plastic stents.

Summary: The study aimed to evaluate the efficacy and safety of hybrid silicon Y stents and covered self-expanding metal stents in restoring airway patency in patients with inoperable malignant airway stenosis and fistulas. The results showed immediate relief of symptoms in a majority of patients after stent placement, significant improvements in dyspnea scores, performance scores, and performance status, with a majority of patients still alive at 6 months without major complications.

Summary: This study aims to evaluate the efficacy of self-expanding metallic stents (SEMSs) in inoperable esophageal cancer (EC) in the western region of Saudi Arabia. The study found that SEMSs are effective in palliating dysphagia without major complications. Rates of tumors in growth and migration were comparable to other studies.

Summary: Background: Pancreatic-enteric drainage procedures are commonly used for the treatment of pancreatic pseudocysts and walled-off pancreatic necrosis. However, the need for pancreatic resection after cyst-enteric drainage procedure in case of recurrence is not well studied. This study aimed to determine the percentage of patients requiring resection due to recurrence after surgical cystogastrostomy and identify predictors of drainage failure. Methods: A retrospective review was conducted on patients who underwent surgical cystogastrostomy between 2012 and 2020. The characteristics of patients, their diseases, and treatment were identified. Failure of surgical drainage was defined as the need for subsequent pancreatic resection due to recurrence. Results: Out of the 24 cystogastrostomies performed, 3 patients (12.5%) required a subsequent distal pancreatectomy after surgical drainage. There was no significant difference in comorbidities between the drainage alone group and the failure of drainage group. However, there seemed to be a trend suggesting that smaller cyst size may be associated with cystgastrostomy failure. Conclusion: Surgical pancreatic drainage was successful in managing pancreatic fluid collections initially. The study did not identify any predictors of failure of initial drainage. Resection with distal pancreatectomy for walled-off pancreatic necrosis and pancreatic pseudocysts should be reserved for cases of drainage failure.

Summary: The study evaluated the efficacy and safety of covered self-expanding metallic stents as a transition to silicone stent implantation for treating severe PTBS, finding that this approach could reduce complications and improve success rates. Patients who received transitional SEMSs had smaller luminal caliber and underwent fewer transbronchial dilations before silicone stent implantation.

Summary: The meta-analysis found that metal stents were more effective than plastic stents in terms of clinical success rate, adverse events rate, and recurrence rate in treating pancreatic fluid collections. Additionally, metal stents required shorter procedure time compared to plastic stents, but there was no significant difference in direct endoscopic necrosectomy use and length of hospital stay between the two.

Summary: Self-expanding sinus stents made of bioabsorbable materials are commonly used in sinus surgery, but complications can occur after implantation. This study evaluated three different materials and analyzed their biomechanical behavior during crimping and deployment. The results showed that the choice of material can significantly affect the contact characteristics of the stents, and PCL may be a suitable option. This study provides insight into the biomechanical characteristics of sinus stents during the implantation process.
