RESUMO
Objective: The study aimed at explore the correlation between the CT-based Peritoneal Carcinomatosis Index (PCI) and pathological parameters of rectal cancer, as well as the correlation with short-term postoperative prognosis. Methods: A retrospective analysis was performed on 198 rectal cancer patients treated in our institution from January 2017 to December 2022. Based on preoperative CT-PCI, patients were classified into a normal and low CT-PCI groups. Baseline characteristics and short-term postoperative outcomes were compared between the two groups. Univariate and Multivariable logistic regression analyses were conducted to ascertain the independent risk factors for postoperative complications (Clavien-Dindo classification ≥ Grade II) following neoadjuvant treatment and radical rectal cancer surgery. Results: There were significant statistical differences between the two groups regarding age, ASA score, and surgical method (P < .05). Variations in overall postoperative complications and complications of Grade II or higher among patients with differing preoperative CT-PCI were statistically significant (P < .05). No significant statistical difference was found in the time to first liquid intake post-surgery between the preoperative low CT-PCI group and the normal CT-PCI group (P > .05); however, differences in the time to first flatus, duration of postoperative hospital stay, and total hospital expenditure were statistically meaningful (P < .05). Multivariate logistic regression revealed that CT-PCI (OR=2.254) was an influential factor for postoperative complications (Clavien-Dindo classification ≥ Grade II) (P < .05). The ROC curve demonstrated an AUC of 0.854 for CT-PCI in predicting postoperative complications (Clavien-Dindo classification ≥ Grade II). Conclusion: Preoperative CT-PCI may be utilized to evaluate the short-term prognosis of patients who undergo radical surgery for rectal cancer after neoadjuvant therapy. This evaluation assists in guiding clinical diagnostic and therapeutic decision-making, allowing for prompt interventions and enhancing short-term patient outcomes.
RESUMO
BACKGROUND AND OBJECTIVE: Transilluminated powered phlebectomy using the TriVex system is a new procedure for minimally invasive varicose vein surgery. We used the TriVex system for the removal of benign superficial subcutaneous soft tissue masses, and we also achieved satisfactory clinical effects. The objective of this study was to explore the feasibility, benefits, and technique-related complications of using the TriVex system for the removal of benign superficial masses as a novel and minimally invasive surgical technique. METHOD: Between January 2010 and August 2016, 452 patients with benign superficial soft tissue masses underwent surgical removal of masses using the TriVex II system in our department. The surgical complications, postoperative cosmetic outcome, and personal satisfaction were reviewed at a mean follow-up of 24 months. RESULTS: The TriVex procedure was successfully completed in all patients using only local tumescent anesthesia without any technical problem and serious complications. The mean operation duration was 8.5 minutes, and the average blood loss was 5 mL. Surgical complications were observed in 69 cases (15.3%) of subcutaneous ecchymosis, 34 cases (7.5%) of skin perforation, 14 cases (3.1%) of subcutaneous hematoma, 13 cases (2.9%) of wound infection, and 7 cases (1.5%) of induration of operation area. Eleven patients (2.4%) showed recurrence during the follow-up and were cured by reoperation by the TriVex system. Overall, the majority of patients (N = 436, 96.5%) were very satisfied or satisfied with the outcome. CONCLUSION: The TriVex procedure for the removal of benign superficial masses is simple, safe, and effective with advantages of short operation time, small incisions, and good cosmetic outcome, which is predicted as a new minimally invasive surgery of superficial masses.
