“…Hirai et al [ 3 ] clarified the anatomic relationship among the ICA, RCA and SMV using 3D images. We also applied 3D imaging during LACS [ 11 ]. The reconstructed 3D image could easily be observed from any angle.…”

“…After predicting the direction of laparoscopic observation of the abdominal organs, a 3D image can be reconstructed for the field of view of the laparoscope [ 19 ]. Our prior study, which involved the use of 3D images, demonstrated that left coronary artery (LCA) branching patterns could be classified into three groups and that the specific distances from the inferior mesenteric artery (IMA) to the LCA branch and the inferior mesenteric vein (IMV) did not significantly differ across these three groups [ 11 ].…”

IntroductionDuring laparoscopic-assisted colorectal surgery (LACS) for right-sided colon cancer patients, we performed three-dimensional (3D) surgical simulation to investigate vascular anatomy, including the ileocolic artery (ICA), right colic artery (RCA) and superior mesenteric vein (SMV).AimWe also used 3D imaging to examine the shortest distance from the root of the ileocolic vein (ICV) to the gastrocolic trunk (GCT).Material and methodsWe analyzed 46 right-sided colon cancer patients who underwent 3D-simulated LACS. We also examined a control group of 20 right-sided colon cancer patients who underwent LACS without 3D imaging. Patients who received such assessments were classified into the following two groups based on the vessel arrangement patterns of the ICA and SMV: the type A group, in which the ICA crosses anterior to the SMV, and the type B group, in which the ICA crosses posterior to the SMV. The shortest length from the root of the ICV to the GCT (D mm) was measured via 3D imaging. Patient characteristics and perioperative outcomes for these three groups were compared.ResultsThe mean D mm for all cases was 29.2 ±5.21 mm. Mean D mm values for the type A and type B groups were 27.8 ±4.21 and 30.5 ±5.53 mm, respectively. Intraoperative blood loss was lower in the type A group (41.8 ±27.5 g) and the type B group (44.5 ±31.6 g) than that in the control group (86.8 ±27.5 g) (p = 0.013).Conclusions3D imaging was useful for understanding anatomical relationships during LACS.

“…A clear understanding of the vascular anatomy of the IMA and inferior mesenteric vein (IMV) is essential for this low-tie procedure. However, there are multiple types of branch vessels originating from the IMA that makes this surgical procedure technically demanding[ 6 ]. We studied the vascular anatomy of the IMA to safely and effectively dissect the lymph nodes around the IMA while preserving the LCA in a laparoscopic procedure for rectal cancer.…”

AIMTo investigate the vascular anatomy of inferior mesenteric artery (IMA) in laparoscopic radical resection with the preservation of left colic artery (LCA) for rectal cancer.METHODSA total of 110 patients with rectal cancer who underwent laparoscopic surgical resection with preservation of the LCA were retrospectively reviewed. A 3D vascular reconstruction was performed before each surgical procedure to assess the branches of the IMA. During surgery, the relationship among the IMA, LCA, sigmoid artery (SA) and superior rectal artery (SRA) was evaluated, and the length from the origin of the IMA to the point of branching into the LCA or common trunk of LCA and SA was measured. The relationship between inferior mesenteric vein (IMV) and LCA was also evaluated.RESULTSThree vascular types were identified in this study. In type A, LCA arose independently from IMA (46.4%, n = 51); in type B, LCA and SA branched from a common trunk of the IMA (23.6%, n = 26); and in type C, LCA, SA, and SRA branched at the same location (30.0%, n = 33). The difference in the length from the origin of IMA to LCA was not statistically significant among the three types. LCA was located under the IMV in 61 cases and above the IMV in 49 cases.CONCLUSIONThe vascular anatomy of the IMA and IMV is essential for laparoscopic radical resection with preservation of the LCA for rectal cancer. To recognize different branches of the IMA is necessary for the resection of lymph nodes and dissection of vessels.

“…The inferior mesenteric artery (IMA) has different branching pattern. Since Latarjet's classification of 1949, many authors, even when using volume‐rendered 3D‐CT, have tried to preoperatively assess the vascular anatomy of the IMA . In summary, three different patterns, types I, II and III, have been described.…”

Three-dimensional reconstruction of the vascular arrangement including the inferior mesenteric artery and left colic artery in laparoscope-assisted colorectal surgery

Abstract: The present 3D reconstruction technique was useful for determining the 3D vascular anatomical pattern including the relative positions of the IMA, SCA, and IMV during laparoscope-assisted left-side colorectal surgery.
