Summary

A Japanese study showed that the additional use of an "Extensive Intraperitoneal Lavage" (EIPL), i.e. an extensive washing of the abdominal cavity with water, during surgery for gastric cancer can lead to a significant increase in survival. However, the study was confined to patients in whom upon commencing surgery, free peritoneal tumor cells were detected, which is only a small fraction of patients.

The primary objective of our study is to assess in all patients undergoing removal of the stomach and adjacent lymph nodes for stomach cancer, if EIPL can eliminate free peritoneal tumor cells which have been present at the beginning of the surgery or after the stomach and lymph node removal. Secondary objectives are to assess how often free peritoneal tumor cells occur in patients with stomach cancer, how often surgical resection itself leads to a release of tumor cells, the safety of the EIPL procedure, and disease-free and overall survival of patients undergoing EIPL. Based on the outcome of this japanese study we want to test with special laboratory methods why this lavage leads to a better outcome.

Specifically, the trial will test the hypotheses that a) lymph node dissection causes a release of tumor cells in the abdominal cavity, and b) EIPL eliminates free peritoneal tumor cells.

Conditions

  • Adenocarcinoma
  • Stomach Neoplasms

Interventions

PROCEDURE

Extensive Intraperitoneal Lavage (EIPL)

EIPL is performed after completing resection and lymphadenectomy: the abdominal cavity has to be washed ten times with one liter Ringer's solution. Each liter has to be well dispersed manually in the abdominal cavity, and removed and disposed completely. 100 ml of the last liter of lavage fluid will be harvested and sent for analysis. Contrary to the Japanese trial, Ringer's solution will be used instead of normal saline solution because of a presumed higher likelihood of peritoneal adhesions when employing the latter (7). Ringer's solution is the standard used for all intraperitoneal lavage procedures at the study centre. To avoid hypothermia, the lavage fluid will be warmed to body temperature (37° Celsius).
