None:
Minimally invasive right hemicolectomy for colon cancer has demonstrated better outcomes than those of open surgery. However, in certain patients, high body mass index, abdominal adhesions, and concomitant cardiopulmonary disease may limit the use of conventional laparoscopy. The use of the retroperitoneal approach preserves the benefits of the minimally invasive approach and expands the range of surgical options. All major steps were performed without access to the abdominal cavity: mobilization, D3 lymph node dissection and vessels ligation. Supplementary video demonstrates a retroperitoneal approach for right hemicolectomy with D3 lymph node dissection that can solve these challenges.

Rate-Determining Steps
In a multistep reaction mechanism, one of the elementary steps progresses significantly slower than the others. This slowest step is called the rate-limiting step (or rate-determining step). A reaction cannot proceed faster than its slowest step, and hence, the rate-determining step limits the overall reaction rate.
The concept of rate-determining step can be understood from the analogy of a 4-lane freeway with a short-stretch of traffic-bottleneck caused due to...

Steps in the Modeling Process
Attention is the first necessary component for observational learning. It involves focusing on what the model is doing and saying. For example, if you decide to take a drawing class to enhance your skills, you need to pay close attention to the instructor's words and hand movements. The characteristics of the model significantly...
