RESUMEN
Purpose: Surgical resection, the primary treatment for colorectal cancer (CRC), is often linked with postoperative complications that adversely affect the overall survival rates (OS). The pan-immune-inflammation value (PIV), a novel biomarker, is promising in evaluating cancer prognoses. We aimed to explore the impact of preoperative immune inflammation status on postoperative and long-term oncological outcomes in patients with CRC. Methods: A retrospective analysis of 203 patients with CRC who underwent surgery (January 2016-June 2020) was conducted. The preoperative PIV was calculated as [(neutrophil count + platelet count + monocyte count) / lymphocyte counts]. The PIV optimal cutoff value was determined based on the OS using the Contal and O'Quigley methods. Results: A PIV value ≥155.90 was defined as high. Patients were categorized into low-PIV (n = 85) and high-PIV (n = 118) groups. Perioperative clinical outcomes (total operation time, time to gas out, sips of water, soft diet, and hospital stay) were not significantly different between the groups. The high-PIV group exhibited more postoperative complications (P = 0.024), and larger tumor size compared with the low-PIV group. Multivariate analysis identified that American Society of Anesthesiologists grade III (P = 0.046) and high-PIV (P = 0.049) were significantly associated with postoperative complications. The low-PIV group demonstrated higher OS (P = 0.001) and disease-free survival rates (DFS) (P = 0.021) compared with the high-PIV group. Advanced N stage (P = 0.005) and high-PIV levels (P = 0.047) were the identified independent prognostic factors for OS, whereas advanced N stage (P = 0.045) was an independent prognostic factor for DFS. Conclusion: Elevated preoperative PIV was associated with an increased incidence of postoperative complications and served as an independent prognostic factor for OS.
RESUMEN
Purpose: This study was performed to evaluate the safety and feasibility of skin adhesives and to compare postoperative and cosmetic outcomes after wound closure in single-port laparoscopic appendectomy (SPLA) between skin adhesives and steri-strips. Methods: This was a single-center retrospective study. We included 22 and 47 patients in whom skin adhesive and steri-strips were used respectively, for skin closure after subcuticular suturing in SPLA between August 2014 and 2020. The patient scar assessment questionnaire (PSAQ) was completed postoperatively to assess postoperative cosmetic outcomes. Results: On the postoperative day, patients in whom skin adhesive was used had significantly lower numeric rating scores than in whom steri-strips were used (2.8 ± 0.8 vs. 3.9 ± 0.8, p < 0.001). The frequency of analgesic administration within 24 hours and between 24 and 48 hours after surgery was significantly lower in the skin adhesive group compared to the wound closure strip group (1.4 ± 0.8 vs. 2.7 ± 1.2, p = 0.013 and 0.2 ± 0.4 vs. 0.7 ± 0.9, p = 0.002, respectively). In the PSAQ, "satisfaction with appearance" and "satisfaction with symptoms" subitem scores were significantly lower in patients in whom skin adhesive was used (11.3 ± 3.0 vs. 15.1 ± 4.5, p = 0.006 and 6.5 ± 1.8 vs. 9.5 ± 3.3, p = 0.003), whereas, "appearance" and "consciousness" subitems revealed no statistically significant differences between the groups. Conclusion: Liquid skin adhesive closures seem to be safe and feasible and cause less postoperative pain, resulting in greater patient satisfaction with postoperative scars than wound closure strip closure after subcuticular suturing in SPLA.
