This study was designed as a prospective observational study.

In this study, the investigator planned to evaluate the effect of blood lactate levels on postoperative gastrointestinal morbidity after paraaortic retroperitoneal lymph node dissection. In gynaecological surgeries, following the removal of the intestines from the surgical field, the retroperitoneal space is entered and the main vessels such as the vena cava inferior and aorta are accessed through the left or right approach depending on the experience and habit of the per-operative surgeon, and total systemic lymph node dissection or bulky lymph node excision is performed depending on the case. During the removal of the intestines from the surgical field, hypoperfusion may develop due to decreased blood flow to the intestines. for this purpose, the investigator planned to investigate the relationship between the change in blood gas lactate values and postoperative gastrointestinal complications in this process.

Inclusion Criteria:

• 18 years

  • Patients undergoing paraaortic retroperitoneal lymph node dissection

Exclusion Criteria:

• Patients with chronic lung disease
• Patients with inflammatory bowel disease
