The transverse colon and splenic flexure remain among the most technically demanding territories in colorectal surgery. Dissection runs close to the pancreas, the jejunum and the middle colic vessels, where precision and thermal control make the difference. In Episode 4 of The Science Behind the Technology, Dr. Francisco Quinteros (Chicago Institute of Advanced Surgery) walks through a complex transverse colectomy step by step: identification and division of the inferior mesenteric vein, medial-to-lateral dissection, ligation of the left colic artery, flexure mobilization from both lateral and medial approaches, dissection of the middle colic branches and construction of the anastomosis. Alongside the case, Rachael Kabala from Medtronic explains the engineering behind LigaSure™ L-Hook and how its design supports precise energy dissection and reliable vessel sealing. A closing panel brings both perspectives together to discuss technique, device selection and practical tips for the OR. Introduced by Dr. Steven D. Wexner, this episode offers surgeons a rare combined view of the technique and the technology behind it.
