The study was aimed to summarize the experience of camera assistant in the "page-turning" 3D laparoscopic right hemi-colectomy with cranial-to-caudal approach.

Data of 43 cases of 3D laparoscopic right colon cancer performed from Oct. 2019 to Feb. 2021 were retrospectively analyzed. Lymph node dissection was performed with Cranial-to-caudal, pre-transected, page-turning approach. Digestive tract reconstruction was performed introcorporally. Summarize skills and attentions of handling camera in the 3 key dissection areas(areas above the transverse mesocolon, areas below the transverse mesocolon, and the areas of page-turning dissection for the right colon).

All of the 43 patients were successfully completed by 3D laparoscopic right hemi-colectomy, without conversion to laparotomy. The mean operation time was(193.5±41.6)min, the average intra operative blood loss was(51.2±45.4)ml, the time-to-flatus was(62.9±15.0)h, and the mean postoperative hospital stay was(9.4±3.0)d. Postoperative tumor stageⅡ in 2 cases、Ⅲ in 18 cases、Ⅳ in 23 cases. The postoperative complications were 5 cases, and 4 of which improved after conservative treatment and 1 improved with laparoscopic surgery. All the patients were followed up for 6-12 months, there were no local recurrence or distant metastases.

The selection and identification of the reference plane, the laparoscopic camera assistant skills and understanding of surgical concept are an important guarantee in the "page-turning" 3D laparoscopic right hemi-colectomy with cranial-to-caudal approach.
