Concomitant Cervical and Anal Screening for Human Papilloma Virus (HPV): Worth the Effort or a Waste of Time?

Background: This study represents a follow-up analysis of the (ANGY) study.

Methods: This prospective, cross-sectional, single-center study recruited women for concomitant cervical and anal screening of HPV genotypes and cytology during a single appointment. All women with findings of either HPV or any type of dysplastic lesions on anal smears were offered follow-up in a specialized high-resolution anoscopy (HRA) outpatient clinic, representing the study cohort for this follow-up study.

Cost Analysis of Outpatient Colectomy in a Tertiary Center: A Projected Medico-Economic Evaluation.

Aim Of The Study: Short stay processes are incentives to unburden chronically stressed healthcare systems. The aim of this study is to analyze financial implications of day admission (DAS) and outpatient strategies for colon resections in a prospective payment system (PPS) using Diagnosis Related Group (DRG) coding.

Methods: Consecutive patients undergoing left and right colonic resections between January 1, 2019 and December 31, 2020 were included.

On-demand robotics-The best of both worlds for robotic-assisted laparoscopic surgery.

A modular, combined use of robotic and laparoscopic platforms has been suggested to address challenges in optimal workspace utilization. The 3-arm on-demand open Dexter Robotic System was developed to combine the advantages of robot-assisted precision surgery in narrow spaces with the laparoscopic approach for frequent position changes in larger spaces. The system integrates 2 patient carts, a fully controllable endoscope arm, and a sterile surgeon open console, allowing for a rapid switch between robot-assisted surgery and laparoscopy.

Be prepared! Impact of structured video-assisted coaching on performance in a simulated bleeding exercise during laparoscopic surgery.

Background: Bleeding during laparoscopic surgery is stressful and requires immediate efficient management. Skills for complication management are rarely trained. This study aims to investigate the impact of video-assisted coaching on laparoscopic skills acquisition and performance in emergency bleeding situations.

Long-Term Outcome of Surgery for Perianal Crohn's Fistula.

: Patients with perianal Crohn's (CD) fistula often need repetitive surgeries and none of the established techniques was shown to be superior or preferable. Furthermore, the long-term outcome of fistula Seton drainage is not well described. The aims of this study were to analyze the long-term healing and recurrence rate of CD perianal fistulas in a large patient cohort.

The number of comorbidities as an important cofactor to ASA class in predicting postoperative outcome: An international multicentre cohort study.

Background: Multimorbidity is a growing burden in our ageing society and is associated with perioperative morbidity and mortality. Despite several modifications to the ASA physical status classification, multimorbidity as such is still not considered. Thus, the aim of this study was to quantify the burden of comorbidities in perioperative patients and to assess, independent of ASA class, its potential influence on perioperative outcome.

Short-term outcomes of surgical treatment for primary ileocaecal Crohn's disease: Results of the Crohn's(urg) study, a multicentre, retrospective, comparative analysis between inflammatory and complicated phenotypes.

Aim: Recent evidence challenges the current standard of offering surgery to patients with ileocaecal Crohn's disease (CD) only when they present complications of the disease. The aim of this study was to compare short-term results of patients who underwent primary ileocaecal resection for either inflammatory (luminal disease, earlier in the disease course) or complicated phenotypes, hypothesizing that the latter would be associated with worse postoperative outcomes.

Method: A retrospective, multicentre comparative analysis was performed including patients operated on for primary ileocaecal CD at 12 referral centres.

Virtual reality simulation training in laparoscopic surgery - does it really matter, what simulator to use? Results of a cross-sectional study.

Background: Virtual reality simulation training plays a crucial role in modern surgical training, as it facilitates trainees to carry out surgical procedures or parts of it without the need for training "on the patient". However, there are no data comparing different commercially available high-end virtual reality simulators.

Methods: Trainees of an international gastrointestinal surgery workshop practiced in different sequences on LaparoS® (VirtaMed), LapSim® (Surgical Science) and LapMentor III® (Simbionix) eight comparable exercises, training the same basic laparoscopic skills.

There is a need for a paradigm shift in laparoscopic surgical training: results of a nationwide survey among teaching hospitals in Switzerland.

Background: Surgical training curricula have changed little over the past decades. Current advances in surgical techniques, especially in minimally invasive surgery, as well as the rapidly changing socioeconomic environment pose a major challenge for the training of young surgeons. The aim of this survey was to provide a representative overview of the surgical training landscape in Switzerland focusing on laparoscopic surgical training: How do department chairs of teaching hospitals deal with the above challenges, and what should a future training curriculum look like?

Methods: This is a prospective, questionnaire-based, cross-sectional study among the heads of departments of all certified surgical teaching hospitals in Switzerland.

Feasibility of on-demand robotics in colorectal surgery: first cases.

Introduction: The key benefits of robotics are improved precision and control, thanks to fully articulated robotic instruments and enhanced, stable endoscope control. However, colorectal procedures also require large movements such as medialization of the colon where a robotic platform is not always needed. We present the world's first experience in colorectal surgery with a new open platform of on-demand robotics.

[Anal cancer screening. A decade's experience of a consultation in a tertiary centre].

Anal cancer is a disease with a low but gradually increasing incidence, especially in developed countries. Most of these cancers are caused by the HPV. In Switzerland, more than 70 % of the sexually active population is infected with HPV at least once, making it the most common sexually transmitted disease.

Impact of Diagnostic Delay on Disease Course in Pediatric- versus Adult-Onset Patients with Ulcerative Colitis: Data from the Swiss IBD Cohort.

Introduction: Given the lack of data, we aimed to assess the impact of the length of diagnostic delay on the natural history of ulcerative colitis (UC) in pediatric (diagnosed <18 years) and adult patients (diagnosed ≥18 years).

Methods: Data from the Swiss Inflammatory Bowel Disease Cohort Study were analyzed. Diagnostic delay was defined as the interval between the first appearance of UC-related symptoms until diagnosis.

[Obstructed colon cancer: which strategy in 2022?].

The key priority for obstructed colon cancer (OCC) is urgent resolution of the large bowel obstruction with ideally no compromise of oncological outcomes and low initial and permanent ostomy rates. Proactive management is pivotal to decrease the risk of perforation and septic shock. Staged procedures have an important place to provide optimal treatment and offer similar treatment and outcomes as in the elective setting.

Closed-wound negative pressure therapy dressing after loop ostomy closure: a retrospective comparative study.

Closed-wound negative pressure wound therapy (NPWT) dressings were recently introduced with the purpose to reduce incisional surgical site infections (iSSI) in high-risk wounds. The aim of this study was to compare iSSI rates in patients after ostomy closure with and without additional application of a closed-wound NPWT dressing. Single-center retrospective analysis of consecutive patients undergoing ileo- or colostomy closure over an 8-year period (January 2013-January 2021).

Modest agreement between magnetic resonance and pathological tumor regression after neoadjuvant therapy for rectal cancer in the real world.

Magnetic resonance imaging (MRI) is routinely used for preoperative tumor staging and to assess response to therapy in rectal cancer patients. The aim of our study was to evaluate the accuracy of MRI based restaging after neoadjuvant chemoradiotherapy (CRT) in predicting pathologic response. This multicenter cohort study included adult patients with histologically confirmed locally advanced rectal adenocarcinoma treated with neoadjuvant CRT followed by curative intent elective surgery between January 2014 and December 2019 at four academic high-volume institutions.

Outcomes of the Composite Anterolateral Thigh Flap for Perineal Reconstruction After Postoncological Abdominoperineal Resection.

Background: The vertical rectus abdominis flap is considered the gold standard in perineal reconstruction after oncological abdominoperineal resection; however, it has a nonnegligible donor site morbidity. The anterolateral thigh flap offers reliable soft tissue coverage.

Objective: The aim was to analyze long-term outcomes of composite anterolateral thigh-vastus lateralis flaps in oncological abdominoperineal resections.

Rate of stoma formation following damage-control surgery for severe intra-abdominal sepsis: a single-centre consecutive case series.

Background: Severe intra-abdominal sepsis (IAS) is associated with high mortality and stoma rates. A two-stage approach with initial damage-control surgery (DCS) and subsequent reconstruction might decrease stoma and mortality rates but requires standardization.

Methods: A standardized two-stage damage-control algorithm for IAS was implemented in April 2016 and applied systematically.
