Laparoscopic distal gastrectomy and hyperthermic intraperitoneal chemotherapy in the treatment of advanced gastric cancer: a retrospective case-matched study on perioperative outcomes.

Abstract

BACKGROUND:

This study aimed to assess the safety and efficacy of laparoscopic distal gastrectomy (LDG) with intraoperative hyperthermic intraperitoneal chemotherapy (HIPEC) for advanced gastric cancer (AGC).

METHODS:

In this case-matched study, we retrospectively reviewed the database of 223 patients with AGC who underwent LDG in Tangdu Hospital from April 2016 to February 2019. Among all participants, 177 patients underwent LDG alone and 46 underwent LDG with HIPEC. We matched total of 138 (1:2) patients from the LDG + HIPEC group (n 46) and the LDG group (n 92) for gender, age, date of operation, and tumor-node-metastasis (TNM) stage of tumor.

RESULTS:

There was no significant difference in the Clavien-Dindo classification of complications between LDG alone and LDG + HIPEC patients. Further analysis showed the morbidity of gastroparesis to be significantly increased in LDG + HIPEC patients. At the same time, we found that the operation time, the time to 1st flatus, and hospital stay were longer in LDG + HIPEC patients and the incidence of abdominal recurrence 2 years after operation was significantly higher in the LDG group than the LDG + HIPEC group.

CONCLUSIONS:

The combination of LDG with intraoperative HIPEC is a safe and feasible method for AGC and HIPEC will limit the recovery of gastrointestinal functions. In addition, during the follow-up of our study, although there was no statistical difference between the two groups in abdominal recurrence at 2 years after surgery, a decreasing trend of abdominal recurrence in LDG + HIPEC patients could be seen in comparison to LDG patients.
