Supervised training of laparoscopic colorectal cancer resections does not adversely affect short- and long-term outcomes: a Propensity-score-matched cohort study.

Background: Supervised training of laparoscopic colorectal cancer surgery to fellows and consultants (trainees) may raise doubts regarding safety and oncological adequacy. This study investigated these concerns by comparing the short- and long-term outcomes of matched supervised training cases to cases performed by the trainer himself.

Methods: A prospective database was analysed retrospectively.

Postoperative morbidity of complete mesocolic excision and central vascular ligation in right colectomy: a retrospective comparative cohort study.

Background: To investigate morbidity and mortality following complete mesocolic excision (CME) and central vascular ligation (CVL) in patients undergoing right colectomy.

Methods: Data from consecutive patients undergoing elective right colectomy at a university-affiliated referral centre were retrospectively analysed. Patients who underwent conventional right-sided colonic cancer surgery (January 2001-April 2009, n = 84) were compared to patients who underwent CME/CVL (May 2009-January 2015, n = 71).

Prior experience in laparoscopic rectal surgery can minimise the learning curve for robotic rectal resections: a cumulative sum analysis.

Background: The learning curve for robotic colorectal surgery is ill-defined. This study aimed to investigate the learning curve of experienced laparoscopic rectal surgeons when starting with robotic total mesorectal excision (TME) using cumulative sum (CUSUM) charts.

Methods: This retrospective case series analysed patients who underwent curative and elective laparoscopic or robotic TMEs for rectal cancer performed by two surgeons.

Laparoscopic-assisted abdominoperineal resection for low rectal cancer provides a shorter length of hospital stay while not affecting the recurrence or survival: a propensity score-matched analysis.

Purpose: To compare the short- and intermediate-term outcomes of open versus laparoscopic abdominoperineal resection (APR) for low rectal cancer.

Methods: Elective open and laparoscopic APRs were identified in a prospective database and were 1:1 propensity score-matched for age, ASA grade, tumour stage and type of neoadjuvant therapy. The short- and intermediate-term outcomes were compared.

Short- and long-term outcomes for patients with splenic flexure tumours treated by left versus extended right colectomy are comparable: a retrospective analysis.

Purpose: To compare the outcomes of colonic splenic flexure tumours treated by extended right colectomy versus left colectomy.

Methods: Stage I-III splenic flexure tumours, treated either by extended right colectomy or left colectomy between 1996 and 2011, were identified in a prospective database, and the short- and long-term outcomes compared. The survival analyses were performed using the Kaplan-Meier method and adjusted using a Cox-proportional hazard model.

Percutaneous transluminal angioplasty of infrainguinal vein graft stenosis is not a negative predictor for long-term patency.

Background: To investigate whether maintenance percutaneous transluminal angioplasty (PTA) for significant stenosis after infrainguinal bypass grafting affects long-term patency of the bypass grafts in comparison to those not needing intervention.

Patients And Methods: The cohort includes 141 consecutive patients with 157 infrainguinal vein grafts performed from January 1996 to December 2005. Grafts occluded within three months after operation were excluded.

Short- and long-term outcomes after laparoscopic versus open emergency resection for colon cancer: an observational propensity score-matched study.

Background: Case series suggest the feasibility and safety of emergency resection of colon cancer by laparoscopy. The present study compares short- and long-term outcomes of laparoscopic and open resection for colon cancers treated as emergencies.

Methods: The study was a propensity score-matched design based on a prospective database.
