CC vs. CC-Plus: A Comparison between Two Cranial-to-Caudal Approaches for Laparoscopic Right Hemicolectomy: A Single-Center Retrospective Study
No full textBackground: Colorectal cancer is a leading cause of cancer-related deaths worldwide, with approximately 1.9 million new cases and over 935,000 deaths in 2020. Right-sided colon cancer, a subset of colorectal cancer, represents a significant health burden. Laparoscopic colon surgery has significantly improved postoperative recovery. The superiority of one approach or landmark over another is still argued about due to the lack of large-scale prospective studies. However, deep understanding both of the anatomical variation and characteristics of each approach is of extreme importance to minimizing adverse effects and maximizing patient benefit after laparoscopic right hemicolectomy. Among these, the cranial-to-caudal approach offers advantages such as reduced intraoperative blood loss, shorter operation time, and decreased risk of vascular injury. The purpose of this study is to compare the efficacy and safety of two cranial-to-caudal approaches for laparoscopic right hemicolectomy (LRH). Specifically, the study aims to evaluate the differences between the conventional cranial-to-caudal approach with medial ligation of the middle colic vein (MCV), and the cranial-to-caudal approach with cranial MCV ligation and surgical trunk sheath opening (CC-plus). The goal is to determine which method offers superior outcomes in terms of intraoperative blood loss, operation time, and overall patient recovery. Materials and Methods: This single-center retrospective study compared two cranial-to-caudal approaches for LRH. The study included 51 patients who underwent LRH between January 2021 and November 2023 at the Second Affiliated Hospital, Zhejiang University School of Medicine. Patients were divided into two groups: Group A (26 patients) used the cranial-to-caudal approach with medial ligation of the middle colic vein (MCV), and Group B (25 patients) used the cranial-to-caudal approach with cranial MCV ligation and surgical trunk sheath opening (CC-plus). General characteristics, intraoperative parameters, and postoperative outcomes were compared. Statistical analysis was performed using SPSS version 20.0, with significance set at p < 0.05. Results: There were no significant differences between the groups regarding age, gender, tumor location, or clinical staging. All patients achieved R0 resection with no perioperative deaths. The CC-plus group had significantly reduced intraoperative blood loss and shorter operation time compared to the CC group (p < 0.05). No significant differences were found in first postoperative exhausting time, first postoperative defecation time, and postoperative hospital stay between the two groups. Furthermore, no significant differences were evaluated in postoperative complications (surgical site infection (SSI), ileus or bowel obstruction, refractory diarrhea, anastomotic leakage, deep vein thrombosis (DVT), hemorrhage) between the two groups on a median follow up of 12.6 months. Pathological examination showed no significant differences in total lymph nodes dissected and tumor stage. Conclusions: The cranial-to-caudal approach with MCV ligation via the cranial approach (CC-plus) is a safe and effective method for LRH, offering advantages in terms of reduced operation time and intraoperative blood loss. This study’s findings suggest that the CC-plus approach may be superior to the conventional cranial-to-caudal approach
Turbulent drag reduction by traveling waves of spanwise forcing
No full textSeveral techniques based on spanwise focing were introduced in the last decade \cite{du-symeonidis-karniadakis-2002, quadrio-ricco-viotti-2009} in the form of traveling waves of spanwise forcing as generalization of the spanwise-wall oscillation technique to reduce skin-friction drag in a turbulent channel flow. Here we examine all their variants (including one that has never been considered before), by addressing the type of forcing (wall movement versus body force) as well as the traveling direction (streamwise versus spanwise) of the waves. We carry out a DNS-based study within an unified framework, to compare their capability to reduce skin-friction drag and, more importantly, net energy savings. The present results confirm the potential for drag reductions for every considered forcing. The best-performing spanwise traveling wave, in terms of either drag reduction or net energy saving, is found to be the one with infinite wavelength, i.e. still the spanwise wall oscillation. The streamwise-traveling waves consistently offer the best performance, especially in terms of net savings. The conditions under which body-force based control can be meaningfully compared to wall based control are discussed

A numerical study for turbulent flow and thermal influence over inhomogenous canopy of roughness elements
No full textA large-eddy simulation with transitional structure function(TSF) subgrid model we previously proposed was performed to investigate the turbulent flow with thermal influence over an inhomogeneous canopy, which was represented as alternative large and small roughness elements. The aerodynamic and thermodynamic effects of the presence of a layer of large roughness elements were modelled by adding a drag term to the three-dimensional Navier–Stokes equations and a heat source/sink term to the scalar equation, respectively. The layer of small roughness elements was simply treated using the method as described in paper (Moeng 1984, J. Atmos Sci. 41, 2052–2062) for homogeneous rough surface. The horizontally averaged statistics such as mean vertical profiles of wind velocity, air temperature, et al., are in reasonable agreement with Gao et al.(1989, Boundary layer meteorol. 47, 349–377) field observation (homogeneous canopy). Not surprisingly, the calculated instantaneous velocity and temperature fields show that the roughness elements considerably changed the turbulent structure within the canopy. The adjustment of the mean vertical profiles of velocity and temperature was studied, which was found qualitatively comparable with Belcher et al. (2003, J Fluid Mech. 488, 369–398)'s theoretical results. The urban heat island(UHI) was investigated imposing heat source in the region of large roughness elements. An elevated inversion layer, a phenomenon often observed in the urban area (Sang et al., J Wind Eng. Ind. Aesodyn. 87, 243–258)'s was successfully simulated above the canopy. The cool island(CI) was also investigated imposing heat sink to simply model the evaporation of plant canopy. An inversion layer was found very stable and robust within the canopy
