Menthol Chewing Gum After Laparoscopic Colorectal Surgery

This randomized controlled trial was conducted to evaluate the effect of menthol chewing gum on postoperative nausea and vomiting, bowel function, and recovery in patients undergoing laparoscopic colorectal surgery. A total of 50 patients were randomly assigned to an intervention group (n=25) or a control group (n=25). Participants in the intervention group received menthol chewing gum in addition to standard postoperative care, while participants in the control group received standard postoperative care only. Nausea, bowel function, and postoperative recovery were assessed during the first three postoperative days.

Effect of Abdominal Ice Pack After vNOTES Hysterectomy

This randomized, controlled, open-label, parallel-group clinical trial is designed to investigate the efficacy of abdominal ice pack application as an adjunct to standard pain management following vNOTES (Vaginal Natural Orifice Transluminal Endoscopic Surgery) hysterectomy. Participants will be randomized in a 1:1 ratio into either the intervention group (ice pack application) or the control group (standard care). Patients in the control group will receive postoperative care adhering strictly to the standard ERAS (Enhanced Recovery After Surgery) protocol. The intervention group will receive abdominal ice pack applications using ice cubes enclosed in a 30x40 cm zipped bag inside a pillowcase, positioned directly on the abdomen from the symphysis pubis to the umbilicus and spanning the distance between both anterior superior iliac spines. Based on the patient's body mass, one or two ice packs will be applied for 20 minutes every two hours during the first 24 hours postoperatively. Physiologically, ice application slows down the metabolic rate of the contact tissue, thereby reducing free radical formation, promoting local vasoconstriction to minimize inflammation and edema, and inhibiting conduction in sensory nerve fibers. The primary hypothesis of this study is that patients receiving ice pack therapy will experience lower postoperative pain scores and decreased analgesic consumption compared to those receiving standard care alone. Ultimately, this trial aims to establish high-level clinical evidence regarding the effects of abdominal ice application on postoperative pain, bowel motility, and overall patient comfort, utilizing standardized questionnaires to assess pain levels and quality of life indices

Effects of HIPEC on Postoperative Bowel Motility and Complications

This retrospective cohort study was conducted at our institution, involving patients with gastric cancer, appendiceal mucinous neoplasm, or colon cancer who underwent CRS with or without HIPEC between January 2017 and December 2023. Patient selection criteria would include all the following: 1) Karnofsky performance status (KPS) score \>50; 2) stage T4b (American Joint Committee on Cancer \[AJCC\] 8th edition stage) or peritoneal metastasis was confirmed during or after surgery; 3) life expectancy \>3 months; 4) peripheral white blood cell count ≥3,500/mm3 and platelet count ≥80,000/mm3; and 5) acceptable liver, renal, cardiovascular, pulmonary, and coagulation function, and other major organ functions were able to endure a major operation. The exclusion criteria were defined as follows: 1) Performance of emergency surgery due to intestinal obstruction or perforation; 2) a history of inflammatory bowel disease (IBD); 3) two or more independent surgical procedures on the gastrointestinal tract; and 4) who received postoperative enema. Patients were divided into two groups based on the treatment strategy: (1) surgery alone (No-HIPEC group); (2) surgery combined with HIPEC (HIPEC group).
