About this trial
Postoperative visceral pain and autonomic symptoms after laparoscopic sleeve gastrectomy may reappear earlier in selected high-risk patients despite standard intraoperative autonomic neural blockade (ANB). Temporary in situ catheter placement permits postoperative ANB redosing when breakthrough visceral symptoms occur.
This prospective single-arm observational study will evaluate the feasibility, safety, and clinical effectiveness of temporary ANB catheter placement and selective postoperative redosing in high-risk patients undergoing laparoscopic sleeve gastrectomy.
