Pancreatic Stent or Rectal Indomethacin-Which Better Prevents Post-ERCP Pancreatitis?: A Propensity Score Matching Analysis.

We investigated and compared 2 clinical strategies to prevent postendoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP).We retrospectively reviewed data from patients who underwent ERCP between 2008 and 2014. Of 623 patients at high risk for PEP, 145 were treated with prophylactic pancreatic stent placement (PSP) only, and 478 were treated with rectal indomethacin (RI) only, for PEP prevention.

Modified laparoscopic intragastric surgery and endoscopic full-thickness resection for gastric stromal tumor originating from the muscularis propria.

Background: This study aimed to evaluate the feasibility and security of the modified laparoscopic intragastric surgery (MLIGS) and the endoscopic full-thickness resection (EFR) for the treatment of gastric stromal tumors (GSTs) originating from the muscularis propria.

Methods: The study population was 18 patients with GSTs of the intraluminal muscularis propria layer. Eight were treated by MLIGS performed according to the following procedures: (1) gastroscopy was used to expose and confirm the location of the tumor; (2) a laparoscope light was placed in the cavity using the trocar at the navel, with the remaining two trocars penetrating both the abdominal and stomach walls; (3) the operation was performed in the gastric lumen using laparoscopic instruments with gastroscope monitoring, and the tumor was resected; (4) the tumor tissue was removed orally using a grasping forceps; (5) and the puncture holes and perforation in the stomach were sutured using titanium clips.

New-style laparoscopic and endoscopic cooperative surgery for gastric stromal tumors.

Aim: To evaluate the feasibility and safety of a new style of laparoscopic and endoscopic cooperative surgery (LECS), an improved method of laparoscopic intragastric surgery (LIGS) for the treatment of gastric stromal tumors (GSTs).

Methods: Six patients were treated with the new-style LECS. Surgery was performed according to the following procedures: (1) Exposing and confirming the location of the tumor with gastroscopy; (2) A laparoscopy light was placed in the cavity using the trocar at the navel, and the other two trocars penetrated both the abdominal and stomach walls; (3) With gastroscopy monitoring, the operation was carried out in the gastric lumen using laparoscopic instruments and the tumor was resected; and (4) The tumor tissue was removed orally using a gastroscopy basket, and puncture holes and perforations were sutured using titanium clips.
