Abstract PDF Supplementary Material: Complete mesocolic excision and central vascular ligation with D3 lymphadenectomy are important surgical principles for improving oncological outcomes in colon cancer. The cranial-first approach is a colonic mobilization–first approach to radical right hemicolectomy, which has several advantages, including early feasibility assessment, safe dissection from surrounding organs, preestablished inferior margin of lymph node dissection, and revelation of the tangible anatomy of the tributaries of the gastrocolic trunk. This video demonstrates the cranial-first approach to radical right hemicolectomy in a 66-year-old man with locally advanced cecal cancer.

Abstract PDF Supplementary Material: The benefits of minimally invasive approaches in colorectal surgery have been well demonstrated. However, some hesitancy remains with regards to the utilization of the robotic platform for total colectomies, mostly due to the perceived need for multiple re-dockings in multiquadrant surgery. This video aims to demonstrate how the robotic platform can be efficiently utilized in multiquadrant surgery without the need for multiple re-dockings, as well as some tips on how to overcome the potential challenges that may be encountered during this procedure.

Abstract PDF Supplementary Material: Lateral pelvic node dissection can be challenging. In addition to detailed anatomical knowledge of the pelvic side wall, surgeons also need to be proficient in performing fine dissection within the confines of this limited operative field. While the incorporation of robotics can facilitate the safe completion of this technically demanding procedure, this is nonetheless dependent on the way the robotic system is used. This video aims to demonstrate several tips and tricks for performing robotic lateral pelvic node dissection.

The aim of this video is to present the procedural details of laparoscopic right hemicolectomy with aortocaval (infrarenal aortic bifurcation) lymphadenectomy, partial resection of the pelvic peritoneum (peritoneal carcinomatosis index, 3), and hyperthermic intraperitoneal chemotherapy in a patient who received neoadjuvant chemotherapy for stage IVc colorectal cancer. The total operation time was 290 minutes, and the patient was discharged on a postoperative day 13 without any complications. No postoperative complications occurred until postoperative day 60. The pathological stage of the tumor was determined to be T3N2bM1c. The pelvic peritoneal nodule was pathologically confirmed as a metastatic lesion. Among the 12 harvested aortocaval lymph nodes, 6 were metastatic lymph nodes. The minimally invasive approach was safe and feasible in this highly selected patient with colon cancer, aortocaval lymph nodes, and peritoneal metastases.

Tumors at the level of the anorectal junction had required abdominoperineal resection (APR) to achieve an adequate resection margin. However, in the cases of tumor invading ipsilateral levator-ani muscle (LAM), en-bloc resection of the rectum with LAM including tumor would be possible. This video is to show the critical anatomic steps of this procedure. A video was produced from the robotic right partial excision of LAM (PELM) performed in a 57-year-old female patient with rectal cancer at 3 cm from the anal verge, invading the ipsilateral anorectal ring, who had received neoadjuvant chemoradiotherapy. The patient discharged at postoperative day 8 without complication. The pathology of the surgical specimen revealed ypT3N1bM0. The secure resection margin from the tumor was achieved. Robotic PELM is the sphincter-preserving technique that can be an alternative treatment option for low rectal cancer invading the ipsilateral LAM, which has been an indication for APR or extralevator APR.

We aimed to show that a standardized step-by-step robotic approach using surgical landmarks could make lateral pelvic lymph node dissection (LPND) less complicated. We performed robot-assisted LPND consisting of 4 steps using surgical landmarks. The first step is a dissection of uretero-hypogastric fascia, which envelopes the ureter and the hypogastric nerve. The second step is a dissection of the medial side of the external iliac vein located at the lateral border of the obturator lymph nodes (LNs) group. The third step is a dissection of the vesico-hypogastric fascia, which is at the medial border of the obturator LNs group. The final step is a dissection of the internal iliac artery until the Alcock’s canal. Indocyanine green was injected just before surgery around the dentate line to identify the lateral pelvic LNs. Standardization using a robotic approach for LPND guided by surgical landmarks allows a safer and more effective surgery.

Abstract PDF Supplementary Material

Situs inversus is a rare hereditary disorder in which various anomalies have been reported with internal rotation abnormalities. This case involved an 85-year-old woman who had been diagnosed with transverse colon cancer and who underwent reduced-port laparoscopic surgery. All intra-abdominal organs were reversed left to right and right to left. The aberrant midcolic artery was identified during surgery. The total surgery time was 170 minutes, and the patient lost 20 mL of blood. The patient was discharged on the 8th postoperative day without complications.
