Summary: 
      Despite significant advances in perioperative care, major complications continue to be seen
      in patients undergoing major surgery. Enhanced recovery after surgery (ERAS) protocols are
      perioperative care practices designed to reduce perioperative complications, maintain
      preoperative organ function, and provide early recovery by reducing the psychological and
      physiological response to major surgery and the intense stress response that develops
      following surgery. In this context, ERAS protocols have been established for many surgical
      procedures. One is the thoracic ERAS (ERATS) protocol applied to thoracic surgery, and the
      evidence for ERATS is increasing; literature data support the application of ERATS. However,
      there are limited studies on the application of ERAS protocols to thoracic surgery, and more
      studies are needed to develop ERATS protocols.

      Postoperative complications may be reduced in patients who are treated with the ERAS
      protocol, their length of hospital stay (LOS) may be shortened, and patients may regain their
      initial functions faster. Objectively, a marker indicating whether the ERAS protocol can be
      implemented effectively has not yet been demonstrated. Reducing postoperative inflammation is
      thought to reduce LOS. Based on this, the investigators think that the early recovery seen in
      patients who undergo ERAS is due to the effect of ERAS protocols on the inflammatory process.
      Therefore, laboratory parameters such as C-reactive protein (CRP), white blood cell count,
      neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), lymphocyte/monocytes
      ratio (LMR) may differ in patients who have undergone the ERAS protocol compared to patients
      who have not. These parameters have been evaluated comprehensively in studies as inflammatory
      parameters. In addition, clinical studies indicate that the C-reactive protein to albumin
      ratio (CAR) can be used as inflammatory and prognostic markers. Also, the investigators
      hypothesized that inflammatory parameters used in routine clinical follow-up may be effective
      in evaluating the clinical consequences of ERATS protocols. In this study, the investigators
      aimed to evaluate the effects of the ERATS protocol on postoperative inflammatory parameters
      and investigate whether these parameters have a role in evaluating the effectiveness of the
      ERATS protocol.
