“…In recent years, with the increasing popularity of multilayer spiral CT scanners and the rapid development of related postprocessing software technology, the diagnostic value of CT examination for gastrointestinal diseases has gained attention [14]. With the use of volumetric CT scan mode, the original data can be reconstructed, and the morphology of the gastrointestinal tract and its relationship with adjacent tissues and organs can be visualized in three dimensions, including multiplanar reconstruction, surface reconstruction, maximum density projection, and volumetric reconstruction [15]. In addition, some new CT examination techniques, such as CT virtual endoscopy (CTVE), gas casting technology, simulated gastrointestinal tract lumen, CT angiography (CTA), CT and perfusion imaging (CTP) [16], are also widely used in clinical practice.…”

Imaging methods for gastrointestinal diseases were based on X-ray imaging until the 1970s, but the development of fiberoptic endoscopy in the 1980s has replaced X-ray imaging. Endoscopy can directly observe the location, size, scope, and color of lesions and obtain pathological results through biopsy, while ligation and other treatments can be performed on polyps and other lesions. Studies have shown that multilayer spiral computed tomography (CT) examination after standardized gastrointestinal preparation and full use of the advantages of various 3D postprocessing reconstruction techniques are of great clinical value in the detection of gastrointestinal diseases, determination of the nature of lesions, localization of lesions, and staging of gastrointestinal malignancies and can make up for the shortcomings of fiberoptic endoscopy, and various 3D postprocessing reconstruction modes have their own advantages and disadvantages. Among them, conventional CT cross-sectional images are the basic images for the diagnosis of various gastric testicular lesions. Axial images, especially thin-layer axial images, can detect the absolute majority of lesions, but there are limitations in observing the anatomical position of lesions, invasion of surrounding tissues, lymph node metastasis, vascularity, and determination of the stage of malignant tumors.

“…As mentioned above, the key points of CME with CVL are to locate the roots of the ICV, ICA and GTH, the right side of the SMV and the left side of the SMA. Previous studies have reported CT-based vascular prediction techniques, but these lack accuracy comparisons [ 25 ] or require additional analysis techniques, such as CT angiography or colonography [ 26 ]. This study evaluated the accuracy of MSCT with coronal reconstruction in predicting critical anatomical sites, and this approach reduced the technical difficulties when used in practice.…”

Background Understanding the vascular anatomy is critical for performing central vascular ligation (CVL) in right hemicolectomy with complete mesocolic excision (CME). This study aimed to investigate the predictive value of multi-slice spiral computed tomography (MSCT) with coronal reconstruction in right hemicolectomy with CME. Methods This is a retrospective descriptive study. Eighty patients with right colon cancer who underwent right hemicolectomy from December 2015 to January 2020 were included. The intraoperative reports (including imaging data) and MSCT images with coronal reconstruction were analysed and compared. The detection rates of the ileocolic vein (ICV) and ileocolic artery (ICA) roots and the accuracy in predicting their anatomical relationship were analysed. The detection rate and accuracy in predicting the location of the gastrocolic trunk of Henle (GTH), middle colic artery (MCA) and middle colic vein (MCV) were analysed. The distance from the ICV root to the GTH root (ICV-GTH distance) was measured and analysed. The maximum distance from the left side of the superior mesenteric artery (SMA) to the right side of the superior mesenteric vein (SMV), named the ‘lsSMA-rsSMV distance’, was also measured and analysed. Results In seventy-four (92.5%) patients, both the ICV and ICA roots were located; their anatomical relationship was determined by MSCT, and the accuracy of the prediction was 97.2% (72/74). The GTH was located by MSCT in 75 (93.7%) patients, and the accuracy of the prediction was 97.33% (73/75). The MCA was located by MSCT in 47 (58.75%) patients, and the accuracy was 78.72% (37/47). The MCV was located by MSCT in 51 (63.75%) patients, and the accuracy of the prediction was 84.31% (43/51). The ICV-GTH distance was measured in 73 (91.2%) patients, and the mean distance was 4.28 ± 2.5 cm. The lsSMA-rsSMV distance was measured in 76 (95%) patients, and the mean distance was 2.21 ± 0.6 cm. Conclusions With its satisfactory accuracy in predicting and visualising the information of key anatomical sites, MSCT with coronary reconstruction has some predictive value in CME with CVL in right hemicolectomy.

“…e consistency between the 3D reconstruction of MSCTA and the actual surgical plane was compared, and the kappa 6 Scientific Programming consistency test K � 0.769 was obtained between the two, which proved that the 3D reconstruction of MSCTA had a good effect in guiding the treatment of laparoscopic CRC. Bian et al [20] also studied and analyzed the clinical guiding significance of MSCTA three-dimensional reconstruction for laparoscopic CRC radical resection. It was concluded that the 3D reconstruction of MSCTA for CRC patients before surgery was helpful to understand the location of colorectal tumors, the anatomical structure of mesenteric blood vessels, and their variations.…”

This study aimed to explore the application effect of magnetic resonance imaging (MRI) based on deep learning in laparoscopic surgery for colorectal carcinoma (CRC). 40 patients with CRC who were diagnosed and required laparoscopic surgery were selected in the research. The MRI scan images of all patients were processed based on the convolutional neural network algorithm. The MRI images before and after treatment were set as the control group and the experimental group, respectively. The consistency of MRI results with laparoscopic and postoperative pathological biopsy results was observed. Through the comparative analysis of the research results, in terms of consistency with the surgical plane, the assessment results of the experimental group were more consistent than those of the control group and direct observation under laparoscopy, and the difference was statistically significant ( P < 0.05 ). In terms of tumor T staging, the consistency between the experimental group and pathological biopsy results was superior to that of the control group, with considerable difference ( P < 0.05 ). In conclusion, practically speaking, the application of MR images based on convolutional neural network algorithm in laparoscopic CRC surgery was better than conventional MRI technology. However, the research was a small-scale pathological study, which was not very representative.
