HIGHLIGHTSSurgical difficulty correlated positively with perioperative mortality and negatively with long-term survival.Prediction model of laparoscopic right hemicolectomy to evaluate the surgical difficulty.Computed tomography parameters were introduced to establish the prediction model.The nomogram incorporating seven independent predictors showed a high C-index.Since it was first described in 2009Previous studies have mainly focused on the establishment and validation of nomograms for predicting surgical difficulty in laparoscopic splenectomy and laparoscopic surgery for rectal cancer and sigmoid cancerPreoperative computed tomography (CT) scanning is recommended to determine the optimal therapeutic strategy for patients with colorectal cancer. CT is applied to detect distant metastasis and is also used as a local staging tool that can measure the tumor size and invasion depth with acceptable accuracies and sensitivitiesThe aim of the present study was to define preoperative predictors (including CT parameters) that affect the surgical difficulty and to establish a preoperative nomogram for predicting the surgical difficulty of minimally invasive right hemicolectomy, thus facilitating the appropriate selection of patients.
