Multidisciplinary team management for prevention of pneumonia and long-term weight loss after esophagectomy: a single-center retrospective study.

Background: In April 2017, we launched the multidisciplinary Hamamatsu Perioperative Care Team (HOPE) for all surgical patients. We developed a reinforced intervention strategy, particularly for esophagectomy. We herein report the outcomes of the HOPE at 2 years after commencement.

Methods: A total 125 patients underwent esophagectomy and gastric conduit reconstruction for esophageal or esophagogastric junction cancer between January 2014 and December 2018 at the Department of Surgery in Hamamatsu University School of Medicine. The patients were divided into the pre-HOPE group including 62 patients who underwent esophagectomy before the introduction of the HOPE and the HOPE group including 63 patients who underwent esophagectomy after the introduction of the HOPE. The outcomes of surgery were compared between the two groups.

Results: There were no significant differences in the clinicopathological characteristics between the two groups. The incidence rates of atrial fibrillation and pneumonia were significantly lower in the HOPE group than in the pre-HOPE group (6% vs. 19%, p = 0.027 and 14% vs. 29%, p = 0.037, respectively). The estimated calorie doses at the time of discharge were approximately 750 and 1500 kcal/day in the pre-HOPE group and the HOPE group, respectively. The body weight loss was significantly less in the HOPE group than the pre-HOPE group at 1, 3, 6, and 12 months postoperatively than that before the surgery (p < 0.001).

Conclusions: The introduction of the multidisciplinary HOPE was associated with a significant reduction in the incidence of postoperative pneumonia and significantly less weight loss.
