BACKGROUND: Incisional hernia (IH) remains a persistent and burdensome complication following colectomy. Through individualized risk-assessment and prediction models, we aim to: 1) improve preoperative risk counseling for patients undergoing colectomy; 2) identify modifiable preoperative risk factors; and 3) encourage the utilization of evidence-based risk prediction instruments in the clinical setting. STUDY DESIGN: A retrospective review of the Healthcare Cost and Utilization Project (HCUP) data was conducted for all patients undergoing either open or laparoscopic colectomy as identified through the state inpatient databases (SID) of California, Florida and New York in 2009...

Surgery that produces an optimal total mesorectal excision (TME) resection specimen remains the cornerstone of curative rectal cancer management. In the modern era, despite the results of recent randomised trials, laparoscopic TME is a crucial technique in the TME surgery armamentarium. Laparoscopic surgery offers the benefit of magnified views that aid sharp and precise dissection. However operating in the confines of a narrow pelvis, particularly when the mesorectum is bulky, requires significant technical skill...

BACKGROUND: Time and accuracy are commonly used metrics to assess laparoscopic skills in a simulated environment. However, they do not provide trainees with meaningful information about how to improve their skills. The objective of this study was to provide preliminary validity evidence for the creation a formative feedback tool (FFT) for advanced laparoscopic suturing skills. METHODS: Videotapes of senior surgical residents (PGY3-5; SRs) and minimally invasive surgeons (MIS) performing 3 advanced laparoscopic suturing tasks were analyzed: needle handling (NH), suturing under tension (UT), and continuous suturing (CS)...

The benefits of electrosurgery have been acknowledged since the early 1920s, and nowadays more than 80% of surgical procedures involve devices that apply energy to tissues. Despite its widespread use, it is currently unknown how the operator's choices with regard to instrument selection and application technique are related to complications. As such, the manner in which electrosurgery is applied can have a serious influence on the outcome of the procedure and the well-being of patients. The aim of this study is to investigate the variety of differences in usage of electrosurgical devices...

Minimally invasive surgery is regarded as an alternative to conventional open surgery in gastric cancer. More and more surgeons devote their efforts to reduce surgical incision and acquire better recovery. Nowadays, laparoscopic distal gastrectomy has been the standard method for early stage cancer with remarkable advantage in short-term outcomes and is widely accepted by patients. The indication of laparoscopic gastrectomy has been extended to local advanced gastric cancer. However, the oncological safety has long been debated...

While laparoendoscopic single-site surgery (LESS) appears to be feasible and safe, instrument triangulation, tissue handling, and other bimanual tasks are difficult even for experienced surgeons. Novel technologies emerged to overcome LESS' procedural and ergonomic difficulties of "tunnel vision" and "instrument clashing." Surgeon kinematics, self-reported workload and upper body discomfort were used to compare straight, bent and two articulating instruments while performing two basic surgical tasks in a LESS simulator...

We report our experience with single-port and multiple-port laparoscopic myomectomy with operative outcomes and surgical skills. Hundred consecutive patients underwent single-port laparoscopic myomectomy (SP-LM) and 69 multi-port laparoscopic myomectomy (MP-LM). The operative outcomes were compared between the two methods. All procedures were successfully completed without conversion to abdominal myomectomy. The mean maximum diameter of the largest myoma was 7.4 (5-13) vs. 6.8 (5-12) cm and the mean number of myomas was 1...

BACKGROUND: Proximal gastrectomy (PG) is widely performed in Japan as a function-preserving surgical approach. Since esophagogastrostomy (EG) was associated with increased reflux symptoms and anastomotic strictures, we have chosen double-tract reconstruction (DTR) as the standard reconstruction method since March 2013. In this study, we described a novel method of laparoscopic DTR using detachable ENDO-PSD and compared its 1-year outcome with EG performed formerly in our institution. METHODS: Patients who underwent laparoscopic PG between May 2005 and July 2014 were retrospectively divided into two groups based on the type of reconstruction and were subsequently analyzed (19 patients in the DTR group and 22 in the EG group)...
