EUS-guided drainage of postsurgical fluid collections using lumen-apposing metal stents: a multicenter study

Retrospective cohort study comparing endoscopic ultrasound‐guided and percutaneous drainage of upper abdominal abscesses

“…Another study presented 47 cases of EUS-D of postsurgical abdominal fluid collections using LAMS; technical success rate was 93.6%, and clinical success rate was 89.3%. 23 Although our study confirms that EUS-D of hepatic and other intra-abdominal abscesses can be carried out safely and effectively using metal stents, its nonrandomized design does not allow us to assess the actual feasibility of EUS-D in difficult locations (e.g. right liver lobe or subphrenic abscesses), which might reduce its utility in a real-life scenario.…”

“…reported 43 EUS‐D using plastic stents of postoperative collections close to the upper GI tract with an overall clinical success rate of 80% and an acceptable adverse event rate (14.6%). Another study presented 47 cases of EUS‐D of postsurgical abdominal fluid collections using LAMS; technical success rate was 93.6%, and clinical success rate was 89.3% . Although our study confirms that EUS‐D of hepatic and other intra‐abdominal abscesses can be carried out safely and effectively using metal stents, its non‐randomized design does not allow us to assess the actual feasibility of EUS‐D in difficult locations (e.g.…”

Transgastric Endoscopic Lumen–Apposing Metal Stents for Intra‐abdominal Fluid Collections After Living Donor Liver Transplantation

“…In contrast, the new technique of EUS-LAMS facilitates access to fluid collections that are adjacent to the gastrointestinal tract, including pancreatic fluid collections caused by pancreatitis and pancreatic surgery. (3,4) Recently, 2 patients who underwent EUS-LAMS drainage after liver transplant were reported as part of a larger study, demonstrating that drainage of pancreatic leakage-associated fluid collections by LAMS has a high technical and clinical success rate with few adverse events. (4) LAMS have wide-flared ends, which minimize the risk of migration and provide a large lumen, allowing for better drainage of fluid collections.…”

“…(3,4) Recently, 2 patients who underwent EUS-LAMS drainage after liver transplant were reported as part of a larger study, demonstrating that drainage of pancreatic leakage-associated fluid collections by LAMS has a high technical and clinical success rate with few adverse events. (4) LAMS have wide-flared ends, which minimize the risk of migration and provide a large lumen, allowing for better drainage of fluid collections. Therefore, use of this new type of stent may result in faster patient recovery than the use of plastic stents or fully covered self-expanding stents.…”

“…Recently, a more advanced technique for EUS-guided drainage of fluid collections that uses lumen-apposing metal stents (LAMSs) to construct a temporary but secure fistula between the stomach and an intra-abdominal fluid collection has been developed and found to have impressive outcomes. (3,4) However, the efficacy of LAMSs for managing intra-abdominal fluid collections after liver transplantation is still unknown. We herein report 2 cases of pancreatic leakage-associated fluid collection after LDLT that were successfully treated by LAMS.Two patients who had developed splenectomyassociated fluid collections were treated with EUS-LAMS.…”
