Single-port Versus Conventional Laparoscopic Colorectal Surgery

ABSTRACT: Conventional multi-port laparoscopic surgery (CL) is now a standard approach to colorectal resections, due to it’s short-term benefits over conventional open surgery. In recent years, several studies have demonstrated that - in suitable patients - single-port access surgery (SPA) has similar clinical outcome compared to CL, with additional cosmetic benefits. It remains, however, unclear whether the trauma of surgery is also less for SPA compared to CL. In this study, the investigators aim to randomise patients who are deemed suitable for SPA surgery to either SPA approach, or CL; in addition to clinical outcomes including length of operating time, post-operative pain scores, complications, quality of life indicators and cosmetic appearance, the investigators aim to compare the physiological response to trauma through biochemical markers (including C-reactive protein, White Blood Cell count) and cytokine expression (i.e. Interleukins IL-6 and IL-8). Patients will be analysed according to intention-to-treat analysis, with 25 patients in the SPA and 25 patients in the CL group. The patients will be operated by surgeons proficient in both CL and SPA surgery, and followed-up for the duration of their hospitalisation as well as at their routine out-patient visits, using questionnaires.

Project description:The study was aimed to identify mechanisms linked to complicated courses after severe trauma by a systems biology approach. In severe trauma, overwhelming systemic inflammation can result in adverse events and the development of complications, including sepsis. In a prospective study, RNA samples from circulating leukocytes from patients with multiple injury (injury severity score â¥ 17) were analyzed for dynamic changes in gene expression over a period of 21 days by whole genome screening. Based on their clinical presentation, patients were divided into two subgroups: patients with secondary sepsis after trauma (n=5) and patients with systemic inflammation without infection (n=5). Expression cluster were defined by correlating gene expression data with clinical outcome parameters. Using unsupervised clustering, patients with systemic inflammation only and patients with sepsis showed a distinct expression pattern and the discrimination of clinical presentation was reflected by clustering of the samples. Explorative gene set analysis revealed robust upregulation of genes related to âhemoglobin metabolism/oxygen transportâ and âpathogenic E.coli infectionâ. 10 patients with multi-system trauma (ISS â¥ 17 points) admitted to the Division of Trauma Surgery at the University Hospital Zurich were included. Whole blood from trauma patients was collected within the first 6 h after trauma (day 0) and on days 1, 2, 3, 5, 7, 10, 14, and 21. Total cellular RNA from circulating leukocytes was isolated using PaxGene Blood RNA Kit (PreAnalytix) for transcriptome profiling. RNA from blood of trauma patients was extracted and subjected to microarray analysis for comparison of longitudinal transcriptomic responses of patients. RNA samples of circulating leukocytes covering time points directly after admission (D0) and on the consecutive days (D1-D21) were subject to multifactorial microarray data analysis: Differences in dynamics of transcripts were assessed by contrasting time- and individual-resolved changes for sepsis and systemic inflammation without infection.
