Aim: The aim of this study was to assess the short-term outcomes of robotic colorectal surgery implemented through a structured, standardized training pathway in five colorectal centres in the United Kingdom.

Method: A multicentre retrospective observational study was conducted, involving 523 consecutive patients who underwent robotic colorectal resection between 2015 and 2019. All participating centres followed the European Academy of Robotic Colorectal Surgery training pathway.

Article Synopsis
  • The study evaluates "textbook oncological outcomes" (TOO), a composite measure of ideal postoperative outcomes from robotic colorectal cancer surgeries.
  • It involved analyzing data from 501 patients over a nine-year period, where 77.4% achieved TOO based on various clinical outcomes.
  • The findings suggest that robotic surgeries overall yield high quality care, but abdominoperineal resection presents a risk factor for not achieving these ideal outcomes.

Purpose: Laparoscopic ileal pouch-anal anastomosis (IPAA) surgery offers improved short-term outcomes over open surgery but can be technically challenging. Robotic surgery has been increasingly used for IPAA surgery, but there is limited evidence supporting its use. This study aims to compare the short-term outcomes of laparoscopic and robotic IPAA procedures.

Enhanced or accelerating recovery programs have significantly reduced hospital length stay after elective colorectal interventions. Our work aims at reporting an initial experience with ambulatory laparoscopic colectomy (ALC) to assess the criteria of discharge and outcomes. Between 2006 and 2016, data regarding patients having benefited from elective laparoscopic colorectal resections in two main centres in the United Kingdom have been analysed.

Purpose: This study was aimed to assess the feasibility of laparoscopic rectal surgery, comparing quality of surgical specimen, morbidity, and mortality.

Methods: Prospectively acquired data from consecutive patients undergoing laparoscopic surgery for rectal cancer, at 2 minimally invasive colorectal units, operated by the same team was included. Locally advanced rectal tumors were identified as T3B or T4 with preoperative magnetic resonance imaging scans.

Purpose: Laparoscopic approach to colonic tumor requires skill set and resources to be established as routine standard of care in most centers around the world. It presents particular challenge in country like Pakistan due to economic constrain and lack of teaching and training opportunities available for surgeons to be trained to deliver such service. The aim of this study is to look into changing practice of our institution from conventional approach of open to laparoscopic surgery for right colon cancer.

Background: Despite there being a considerable amount of published studies on robotic colorectal surgery (RCS) over the last few years, there is a lack of evidence regarding RCS training pathways. This study examines the short-term clinical outcomes of an international RCS training programme (the European Academy of Robotic Colorectal Surgery-EARCS).

Methods: Consecutive cases from 26 European colorectal units who conducted RCS between 2014 and 2018 were included in this study.

Purpose: Obesity, neoadjuvant-radiotherapy, tumour proximity to the anal verge and previous abdominal surgery are factors that might increase the intra-operative difficulty of laparoscopic rectal cancer surgery. However, whether patients with these 'high-risk' characteristics are subject to worse short- or long-term outcomes is debated. The aim of this study is to examine the short- and long-term clinical and oncological outcomes of patients receiving laparoscopic rectal surgery with any of these high-risk characteristics and compare them with patients that do not possess any of these high-risk features.

Purpose: Pilonidal sinus disease (PD) is a common acquired disease, responsible for discomfort and time off work. There is currently no consensus on the best surgical therapy. We aimed at comparing conservative sinusectomy (S) to excision and paramedian primary closure (PC).

Purpose: A structured training programme is essential for the safe adoption of robotic rectal cancer surgery. The aim of this study is to describe the training pathway and short-term surgical outcomes of three surgeons in two centres (UK and Portugal) undertaking single-docking robotic rectal surgery with the da Vinci Xi and integrated table motion (ITM).

Methods: Prospectively, collected data for consecutive patients who underwent robotic rectal cancer resections with the da Vinci Xi and ITM between November 2015 and September 2017 was analysed.

Purpose: Laparoscopic rectal surgery in obese patients is technically challenging. The technological advantages of robotic instruments can help overcome some of those challenges, but whether this translates to superior short-term outcomes is largely unknown. The aim of this study is to compare the short-term surgical outcomes of obese (BMI ≥ 30) robotic and laparoscopic rectal cancer surgery patients.

Aims: In rectal cancer, increasing the interval between the end of neoadjuvant chemoradiotherapy (CRT) and surgery could improve the pathological complete response (pCR) rates, allow full-dose neoadjuvant chemotherapy, and select patients with a clinical complete response (cCR) for inclusion in a "watch & wait" program (W&W). However, controversy arises from waiting more than 8-12 weeks after CRT, as it might increase fibrosis around the total mesorectal excision (TME) plane potentially leading to technical difficulties and higher surgical morbidity. This study evaluates the type of surgical approach and short term post-operative outcomes in patients with rectal cancer that were operated before and after 12 weeks post CRT.

Background: As obesity becomes more prevalent, it presents a technical challenge for minimally invasive colorectal resection surgery. Various studies have examined the clinical outcomes of obese surgical patients. However, morbidly obese patients (BMI ≥ 35) are becoming increasingly more common.

Laparoscopic colonic resections often require manipulation and surgical action in all abdominal quadrants. Port placement, a fundamental part of a successful procedure, often varies widely among surgeons and is currently dictated by individual experience and preference. This variability may be suboptimal for the operation at hand, can be confusing for trainees and many times provide inadequate working posture for the surgeons, resulting in discomfort due to muscular fatigue in the hands, arms, shoulders and cervical spine.

Background: Laparoscopic surgery for patients with Crohn's disease (CD) is considered challenging. The aim of this study is to evaluate the clinical outcomes of laparoscopic bowel resection in patients with CD. We also assessed the effectiveness of the laparoscopic approach in recurrent or emergency surgery due to CD.

Robotic rectal surgery is becoming increasingly more popular among colorectal surgeons. However, time spent on robotic platform docking, arm clashing and undocking of the platform during the procedure are factors that surgeons often find cumbersome and time consuming. The newest surgical platform, the da Vinci Xi, coupled with integrated table motion can help to overcome these problems.

Aim: Laparoscopic rectal surgery is associated with a steep learning curve and high conversion rate despite progress in equipment design and consistent practice. The robotic system has shown an advantage over the laparoscopic approach due to stable three-dimensional views, improved dexterity and better ergonomics. These factors make the robotic approach more favourable for rectal surgery.
