Purpose: The purpose of this study was to investigate the effects of postoperative complications on long-term survival after laparoscopic surgery for resectable colorectal cancer.

Methods: We retrospectively included 204 patients who underwent laparoscopic surgery for colorectal cancer from January 2016 to June 2020.

Results: Overall, 68 (33.3%) patients had postoperative complications, twelve (17.6%) of which were classified as Clavien-Dindo class 3a or higher. The 5-year overall survival rate of the non-complication and complication groups were 93.0% and 81.7%, respectively (p = 0.048; Kaplan-Meier analysis and log-rank test), and those among patients with stage III disease were 87.0% and 61.3%, respectively (p = 0.045). The 5-year disease-free survival rates were 85.6% and 77.4%, respectively (p = 0.042). Multivariable Cox proportional-hazards analysis revealed that nodal stage (hazard ratio, 8.392; 95% confidence interval, 1.892-37.175; p = 0.005) was an independent prognostic factor for overall survival, and postoperative complications (hazard ratio, 2.996; 95% confidence interval, 1.076-8.340; p = 0.036) were independent prognostic factors for disease-free survival.

Conclusion: Postoperative complications were associated with poor oncological outcomes, especially among patients with stage III colorectal cancer, and independent prognostic factors for disease-free survival.

Airway compromise due to prevertebral soft tissue swelling is a potentially devastating complication following anterior cervical discectomy and fusion (ACDF). However, there are no studies on the postoperative patient posture for enhancing airway patency after ACDF. This study aimed to analyze the effect of neck and mouth postures on airway patency following ACDF and to suggest the beneficial postoperative patient posture for improving airway patency.

Despite the growing adoption of laparoscopic hepatectomy (LH) for intrahepatic cholangiocarcinoma (ICC), there is no scoring system available designed to evaluate its surgical complexity. This paper aims to introduce a novel difficulty scoring system (DSS), designated as the Wei-DSS, exclusively tailored to assess the surgical difficulty of pure LH for ICC. We retrospectively collected clinical data from ICC patients who underwent pure LH at our institution, spanning from November 2018 to May 2024.

The management of papillary thyroid carcinoma (PTC) concurrent with Hashimoto's thyroiditis (HT) lacks standardized guidelines, especially concerning surgical strategies. This study aimed to compare unilateral thyroidectomy (UT) with total thyroidectomy (TT) in PTC-HT patients to optimize clinical management and improve postoperative outcomes. This retrospective study included PTC-HT patients undergoing thyroid surgery at a tertiary academic medical institution from January 2018 to August 2023.

Objective: This study aims to enhance compliance with lower limb lymphedema (LLL) prevention care measures post-gynecologic oncology surgery (GOS) through quality control circle (QCC) activity, aiming to improve patient recovery outcomes and reduce postoperative complications.

Methods: A 6-month QCC activity was conducted within the hospital, employing the ten-step plan-do-check-act model for QCC activity. The root causes of inadequate implementation of LLL prevention care measures were analyzed, leading to the development of relevant strategies and protocols.
