Feasibility of Pylorus-Preserving Gastrectomy With a Wider Scope of Lymphadenectomy

摘要: Objective To demonstrate the feasibility and safety of pylorus-preserving gastrectomy (PPG) accompanied by complete suprapyloric infrapyloric lymph node dissection. Design Retrospective review. Setting A university hospital in Japan. Patients Fifteen patients underwent PPG, 28 conventional distal (CDG) with Billroth I anastomosis. All had early gastric cancer, either limited invasion mucosal layer or into submucosal layer. Interventions In PPG procedure, part stomach was resected while retaining a 1.5-cm pyloric cuff. The right gastroepiploic artery, hepatic branches vagus nerve were divided, artery preserved. modified D1 D2 lymphadenectomy PPG. Main Outcome Measures undergoing CDG procedures assessed 1 year after their surgical procedure. Changes body weight, serum total protein levels, albumin incidence dumping syndromes, endoscopic findings remnant compared between 2 groups. Results Weight loss significantly less group than (P=.02). incidences especially vasomotor symptoms, lower (P=.03 andP=.02, respectively). sphincter function preserved, there no anastomotic leakage group. Conclusions procedure can be performed safely low major complications better postoperative outcome recommended for treatment cancer broader indications.
