A novel caudal-dorsal approach for laparoscopic right hemicolectomy with complete mesocolic excision.

PURPOSE: We aimed to demonstrate a novel caudal-dorsal approach laparoscopic right hemicolectomy (LRH) for a patient diagnosed with right colon carcinoma.

METHOD: We performed a LRH with a caudal-dorsal approach. We started the operation from the distal root of the small intestine mesentery and the backside of the ascending colon. The ileocolic artery and vein were transected at the dorsal side of the mesocolon. The superior mesenteric vein (SMV) and the gastrocolic trunk were dissected from the dorsal approach. The study adhered to the IDEAL. We followed the recommendations of the LAP-VEGaS Consensus for the reporting of Laparoscopic Videos [1].

RESULTS

The operation lasted approximately 120 min, with an intraoperative blood loss of only 10 mL. Postoperative pathology showed pT1N0M0 (18 lymph nodes resected, all negative for metastasis). The patient was discharged on postoperative day 5 without complications.

CONCLUSION

The caudal-dorsal approach for LRH represents a novel surgical method, and we believe it offers several advantages over traditional approaches.
