Review Meta Analysis
Incidence of incisional hernia in the specimen extraction site for laparoscopic colorectal surgery: systematic review and meta-analysis.
The incidence of incisional hernia(IH) may be affected by the choice of specimen extraction incision. The objective of this study was to perform a systematic review and meta-analysis comparing the incidence of IH after midline and off-midline incisions in patients undergoing laparoscopic colorectal surgery. ⋯ Midline incisions for specimen extraction in laparoscopic colorectal surgery are at significantly higher risk of IH compared to off-midline (transverse or Pfannenstiel) incisions, but these data are of poor quality and heterogeneous.

The challenge of performing a good total mesorectal excision (TME) dissection, particularly in the distal 1/3 of the rectum, has spurred interest in new techniques. Robotic surgery is advocated by some, and more recently, a "new" approach, the transanal total mesorectal excision, has been popularized to address this problem. While great interest in this technique exists, little long-term outcome data are available. We have been utilizing a transanal abdominal transanal approach to TME in order to facilitate the distal dissection, and here, we provide our long-term outcomes using this approach in the management of rectal cancer. ⋯ This is the first report of long-term data using a transanal approach to TME supporting this approach for rectal cancer. Our data with 5-year follow-up show that adequate distal and circumferential margins with very good-quality TME specimens, and a low risk for LR with excellent overall survival can be achieved using this technique. Our long-term results support the promising reports of early experiences in the literature.

Extending the clinical indications for laparoscopic liver resection (LLR) should be carefully considered based on a surgeon's experience and skill. However, objective indexes to help surgeons assess the estimated difficulty of LLR are scarce. The aim of our study was to develop the first objective numerical rating scale to predict the surgical difficulty of various LLR procedures. ⋯ Our novel model will be useful for surgeons to predict the difficulty of an LLR procedure relative to their own experience and skill.

Incisional hernia (IH) is a frequent occurrence following open surgery for Crohn's disease (CD). This study compares the IH rates of patients with CD undergoing open versus laparoscopic bowel resection. ⋯ A marked decrease or complete elimination of IH in patients with CD undergoing bowel resection may be possible using advanced laparoscopic techniques that require intra-abdominal anastomosis and use of the smallest transverse extraction incisions.

Observational Study
Development and validation of a tool for non-technical skills evaluation in robotic surgery-the ICARS system.
Non-technical skills (NTS) are being increasingly recognised as vital for safe surgical practice. Numerous NTS rating systems have been developed to support effective training and assessment. Yet despite the additional challenges posed by robotic surgery, no NTS rating systems have been developed for this unique surgical environment. This study reports the development and validation of the first NTS behavioural rating system for robotic surgery. ⋯ ICARS is the first NTS behavioural rating system developed for robotic surgery. Initial validation has shown it to be an effective and reliable tool. Implementation of ICARS will supported structured training and assessment of NTS within the robotic surgical curriculum.
