About this trial
The study evaluates the efficacy of Ropivacaine-Poloxamer 407 hydrogel in reducing postoperative pain following open gastrectomy.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Patients with a histologically confirmed diagnosis of gastric adenocarcinoma prior to surgery.
Patients who have undergone a complete surgical resection (R0 resection).
Patients with an ASA (American Society of Anesthesiologists) score of 3 or below.
Patients aged 20 years or older.
Disqualifiers
Patients under 19 years of age.
Presence of ascites or peritoneal metastasis.
Patients who have undergone preoperative chemotherapy or radiotherapy.
Diagnosis of malignancies other than gastric cancer.
Trial design
Parallel
Treatments tested in this trial
Arm I (Peritoneal application group)
Procedure/SurgeryAt the end of gastrectomy, during closure of incision, peritoneum and fascia are closed by suture, layer by layer. Skin approximation is doen with skin stapler. Ropivacaine-Poloxamer 407 hydrogel is applied on space between peritoneum and fascia in Arm I.
Arm II (Subcutaneous injection group)
Procedure/SurgeryAt the end of gastrectomy, during closure of incision, peritoneum and fascia are closed by suture, layer by layer. Skin approximation is doen with skin stapler. Ropivacaine-Poloxamer 407 hydrogel is injected on subcutaneous area in Arm II.
Treatment groups
Trial outcomes
Primary outcomes
Total fentanyl consumption within 72 hours postoperatively.
The total amount of fentanyl administered to the patient via IV PCA during the initial 72-hour postoperative period will be recorded and compared among groups to assess analgesic efficacy.
Secondary outcomes
Pain intensity scores (NRS) at rest and during movement.
Pain intensity: Numerical Rating Scale (NRS) scores ranging from 0 (no pain) to 10 (worst pain) assessed both at rest and during movement.
Time to first flatus and bowel movement.
Bowel function: Time to resume normal gastrointestinal activity.
Occurrence of postoperative nausea and vomiting (PONV).
PONV: Incidence of nausea and vomiting documented along with severity scores.
Wound healing assessment, including seroma and infection rates.
Wound healing: Observation of seroma or infection at the surgical site.
