Abstract
Clinical studies have established the safety and advantages of laparoscopic surgery for gastric cancer; therefore, laparoscopic gastrectomy (LG) in clinical practice is increasing. We report the case of a 77-year-old patient with gastric cancer who was referred to our center for LG. Esophagogastroduodenoscopy revealed a type 3 tumor identified as adenocarcinoma on biopsy. Three-dimensional computed tomography-angiography revealed two left gastric arteries (LGAs) branching from the celiac trunk. By laparoscopically performing the outermost layer-oriented lymphadenectomy (OML-OL), the two LGAs were detected and appropriately divided. Subtotal gastrectomy was completed, and the patient had an uneventful postoperative course. The OML-OL was appropriate for LG in this situation. This case demonstrates the necessity of preoperative three-dimensional computed tomography-angiography with 1-mm slices and the importance of performing OML-OL.

Abstract
BACKGROUND To perform laparoscopic gastrectomy safely, we aimed to comprehensively re-evaluate perigastric vessel anatomies using a three-dimensional angiography reconstructed from enhanced multidetector-row computed tomography data. METHODS Perigastric vessel anatomy was preoperatively analyzed using a multidetector-row computed tomography-based three-dimensional angiography reconstructed in 127 patients undergoing gastric surgery. RESULTS Of the 67 left gastric veins that ran along the dorsal side of the arteries, 59 (88.1%) ran along the dorsal side of the common hepatic artery and flowed into the portal vein. In 18 cases, a common trunk of one to three left gastric arteries and the replaced left hepatic artery was observed. The left inferior phrenic artery ramified from the left gastric artery in 5.5% of the cases. The right gastric artery was classified into distal (73.2%), caudal (18.1%), and proximal (8.7%) types. The infra-pyloric artery was also classified into distal (64.6%), caudal (26.0%), and proximal (9.4%) types. The posterior gastric artery branched as a common trunk with the superior polar artery in the proximal (37.9%) and distal (18.4%) regions of the splenic artery. The left gastroepiploic artery ramified from the splenic (18.1%) and inferior terminal arteries (81.9%). No, one, and two gastric branches of the left gastroepiploic artery, which ramified between the roots of the left gastroepiploic artery and its omental branch, were found in 36.5%, 49.2%, and 14.3% of the cases, respectively. CONCLUSIONS Preoperative 3D angiography is useful for the precise evaluation of perigastric vessel anatomies, and may help us to perform laparoscopic gastrectomy and robotic surgery safely.

Abstract
Background Typically, the celiac trunk and superior mesenteric artery branch off separately from the anterior aspect of the abdominal aorta. The celiacomesenteric trunk (CMT) is a rare variant in which those arteries share a common origin. We sought to compare the prevalence of CMT in the Caribbean with the global prevalence as calculated by a systematic review. Methods In this study, we evaluated all consecutive patients who had multiphase contrast-enhanced CT scans at two major referral centres in the Caribbean from August 30, 2017, to September 1, 2019. In patients with a CMT, we recorded demographic and anatomic details. We then conducted a systematic literature search and retrieved raw data to calculate the global prevalence (number of individuals with a CMT divided by the sum total of study samples). We compared CMT prevalence in our sample with the global prevalence using Pearson's chi-square and Fisher's exact tests. Statistical significance was considered to be present when the P value was <0.05. Results From 832 CTs, 665 scans met the inclusion criteria. There were 16 (2.41%) CMTs: 3 (0.45%) classic CMTs, 12 (1.8%) hepato-mesenteric trunks, and 1 (0.15%) hepato-spleno-mesenteric trunk. Forty-two studies reported on CMTs in a total of 74,320 persons. The global CMT prevalence was comparable (3.88%; P = 0.054), but the incidence of hepato-mesenteric variants was significantly lower in our sample (1.8% vs. 3.24%; P = 0.0352). Conclusion There was no difference in the prevalence of a classic CMT in the Caribbean compared to the global prevalence. However, the hepato-mesenteric trunk (incomplete CMT variant) was significantly less prevalent in the Caribbean. Advances in Knowledge: Healthcare professionals performing hepatobiliary interventions must be aware of these differences in order to minimize morbidity during their interventions.

Abstract
To investigate the clinical value and significance of preoperative three-dimensional computerized tomography angiography (CTA) in laparoscopic radical gastrectomy for gastric cancer. The clinical data were analyzed retrospectively from 214 gastric cancer patients. We grouped according to whether to perform CTA, and we compared and analyzed the difference of the data between the two groups. The perigastric arteries were classified according to CTA images of patients in the CTA group. The celiac trunk was classified according to Adachi classification: Type I (118/125, 94.4%), Type II (3/125, 2.4%), Type III (0/125, 0%), Type IV (1/125, 0.8%), Type V (2/125, 1.6%), Type VI (1/125, 0.8%). Hepatic artery classification was performed according to Hiatt classification: Type I (102/125, 81.6%), Type II (9/125, 7.2%), Type III (6/125, 4.8%), Type IV (2/125, 1.6%), Type V (3/125, 2.4%), Type VI (0, 0%), Others (3/125, 2.4%). And this study combined vascular anatomy and surgical risk to establish a new splenic artery classification model. In comparison, the operation time, first exhaust time, and estimated blood loss in the CTA group were significantly lower than those in the non-CTA group. In addition, the blood loss in the CTA group combined with ICG (Indocyanine Green) labeled fluorescence laparoscopy was significantly less than that in the group without ICG labeled. Preoperative CTA could objectively evaluate patients' vascular route and variation and then help us avoid or decrease the risk of vascular injury and bleeding. When combined with ICG labeled fluorescence laparoscopy, it could further reduce the risk of iatrogenic injury during the operation and improve postoperative recovery.

Abstract
Background The left gastric vein (LGV) plays an important role in laparoscopic radical gastrectomy (LRG). However, the anatomy of the LGV is complicated with significant variation, and it is often damaged and bleeding during LRG. The purpose of this study was to observe and analyze the anatomic types of the LGV in patients undergoing LRG and to explore its clinical significance. Methods A total of 217 patients who underwent LRG from June 2016 to December 2020 were included. LGVs were divided into four types according to the relationship between the LGV and peripheral arteries [celiac artery (CA)/common hepatic artery (CHA)/splenic artery (SA)] and the pancreas during LRG. If a LGV was damaged during surgery (resulting in bleeding), it was included in the bleeding group. Non-bleeding groups were included if there was no impairment to the LGV. Results A total of four types of LGVs were observed, of which type I was the most prevalent, accounting for 58.8% (n=121). In 21 patients (9.7%), the LGV was injured and hemorrhagic during LRG; and the type IV LGV injury bleeding rate was as high as 41.7% (5/12). Univariate analysis revealed that the extent of lymph node dissection (LND), pathological stage, tumor (T) stage, and type of LGV were significantly associated with LGV injury and hemorrhage (P<0.05). Multivariate analysis showed that enlarged LND, late T stage, late pathological stage, and type IV LGV were independent risk factors for LGV injury hemorrhage. Conclusions LGVs that run between the CHA (posterior) and the CA into the portal venous system were the most common anatomical type. A LGV that runs between the SA (posterior) and the CA into the portal venous system is easily injured (resulting in bleeding). LGV injury and hemorrhage are affected by a variety of factors, and therefore, careful intraoperative dissection is necessary to avoid damage to the LGV.

Abstract
BACKGROUND Minimally invasive distal pancreatectomy (MIDP) is increasingly performed worldwide; however, the surgical anatomy required to safely perform MIDP has not yet been fully considered. This review evaluated the literature concerning peripancreatic vascular anatomy, which is considered important to conduct safe MIDP. METHODS A database search of PubMed and Ichushi (Japanese) was conducted. Qualified studies investigating the anatomical variations of peripancreatic vessels related to MIDP were evaluated using SIGN methodology. RESULTS Of 701 articles yielded by our search strategy, 76 articles were assessed in this systematic review. The important vascular anatomy required to recognize MIDP included the pancreatic parenchymal coverage on the root and the running course of the splenic artery, branching patterns of the splenic artery, confluence positions of the left gastric vein and the inferior mesenteric vein, forms of pancreatic veins including the centro-inferior pancreatic vein, characteristics of the left renal vein, and collateral routes perfusing the spleen following Warshaw's technique. Very few articles evaluating the relationship between the anatomical variations and surgical outcomes of MIDP were found. CONCLUSIONS The precise knowledge of peripancreatic vessels is important to adequately complete MIDP. More detailed anatomic analyses and descriptions will benefit surgeons and their patients who are facing these operations.

Abstract
Introducción. Al realizar una gastrectomía distal, el remanente gástrico es irrigado por los vasos gástricos cortos. En este estudio presentamos una serie de casos de gastrectomía distal laparoscópica, con la variante de preservar la rama superior de la arteria gástrica izquierda, con un remanente gástrico pequeño.
Métodos. Estudio observacional con intensión analítica, seguimiento de una cohorte retrospectiva de pacientes con cáncer gástrico sometidos a gastrectomía distal radical laparoscópica entre enero 2017 y junio 2019. Se incluyeron todos los pacientes con cáncer gástrico a quienes se les realizó gastrectomía distal radical por laparoscopia. Se estudiaron variables clínicas de los pacientes, variables intraoperatorias, información relacionada con el informe de patología y las complicaciones de la anastomosis gastro-yeyunal.
Resultados. Se revisó un total de 61 historias clínicas de pacientes sometidos a gastrectomía distal por laparoscopia, entre quienes se encontró la preservación de la rama ascendente de la arteria gástrica izquierda en el 73,8 % de los pacientes (n=45). El promedio de ganglios resecados fue de 24. Se presentaron un total de 10 complicaciones, ocho relacionadas con la anastomosis (tres estenosis, cuatro filtraciones y un paciente con hemorragia del tracto digestivo superior), y dos con colecciones intrabdominales. En el análisis estadístico no se encontró relación entre la preservación de la rama ascendente de la arteria gástrica izquierda con la presencia de complicaciones.
Discusión. La variación que presentamos de la técnica de la gastrectomía distal por laparoscopia cumple con los requisitos oncológicos en los pacientes con cáncer gástrico y no se relaciona con complicaciones de la anastomosis gastró-yeyunal.

Abstract
PURPOSE To investigate the prevalence and patterns of aberrant gastric venous drainage and associated atrophy of the hepatic segment on contrast-enhanced computed tomography (CT). METHODS Two radiologists retrospectively reviewed contrast-enhanced CT images from 2021 patients who underwent cone-beam CT-guided chemoembolization between January 2013 and December 2018. They determined the presence or absence of an aberrant gastric vein(s) and its drainage site by consensus, and qualitatively analyzed the presence or absence of atrophy of segments II or III. In cases of disagreement between the two reviewers regarding the presence of atrophy, quantitative analysis was performed using dedicated software. RESULTS A total of 31 aberrant right gastric veins were revealed on CT (1.5%), most of which drained into P2 (n = 8), the S2/3 border zone (n = 8), S2 (n = 6), or S4 (n = 5). An aberrant left gastric vein was observed in 21 (1.0%) patients, and P2 was the most common drainage site (n = 13) in these patients. Atrophy of segment II was more frequently observed among patients with aberrant gastric veins than among those without (26.9% versus 4.1%; p < 0.001). In addition, an aberrant gastric vein draining into P2 was most frequently accompanied by segment II atrophy (47.6%). CONCLUSION Aberrant right and left gastric veins were observed in 1.5% and 1.0% of patients, respectively. Atrophy of segment II was frequently observed in patients with aberrant gastric veins, especially those that drained into P2.

Abstract
In recent years multidetector computed tomography (MDCT) has been used to investigate vascular anatomy for scientific and diagnostic purposes. These studies allow for much larger sample sizes than traditional cadaveric studies. The aim of this research was to perform a systematic review and meta-analysis on studies investigating the variations of the celiac trunk using MDCT. Major medical databases were used to find studies investigating celiac trunk anatomy using MDCT. Extracted information included demographic details, number of normal celiac trunks, and number of each variant celiac trunk. Using a random effects meta-analysis the pooled prevalence of each variation was calculated. A total of 36 studies from 14 countries and four continents were included in the meta-analysis. The total number of subjects included was 17,391. The total prevalence of variant celiac trunks was 10.85%. The different types of celiac trunk variations with their prevalences were: gastrosplenic trunk (3.46%), hepatosplenic trunk (3.88%), hepatogastric trunk (0.24%), absent celiac trunk (0.28%), celiacomesenteric trunk (0.46%), hepatosplenomesenteric trunk (0.26%), gastrosplenomesenteric trunk (0.07%), and celiacomesenteric anastomosis (0.09%). A total of 61 cases (0.19%) were either not described or not described adequately to be included in our classification. Major variations of the celiac trunk are not uncommon and should be anticipated before radiological and surgical interventions. Knowledge of celiac trunk anatomy is important in hepatopancreatobiliary surgery, transplantology, and interventional radiology.

Abstract
BACKGROUND Surgeons normally encounter the left gastric vein (LGV) during laparoscopic gastrectomy (LG) for gastric cancer, and the various anatomic variants of this vessel make the procedure difficult. The objective of this study was to classify anatomic variants of the LGV in the laparoscopic operation field and clarify their clinical significance during LG. METHODS In total, 405 patients who underwent LG in 2013-2017 for gastric cancer were enrolled in the study. LGV drainage was classified into six types by the anatomic relation of the LGV to the arteries of the celiac axis: Type Ia [LGV runs anteriorly to the common hepatic artery (CHA)], Type Ip (LGV runs posteriorly to CHA), Type II (LGV runs anteriorly to the left gastric artery), Type IIIa [LGV runs anteriorly to the splenic artery (SA)], Type IIIp (LGV runs posteriorly to SA), and Type IV (LGV runs cranially into the proximal portal vein or liver parenchyma). If the LGV was injured during the operation, the patient was included as a member of the injury group (IG). RESULTS Most patients (n = 391, 96.5%) had a single LGV, whereas 14 (3.5%) patients had double LGVs. Type Ip was the most common of the six drainage types (n = 195, 48.1%). The number of patients in the IG was 49 (13.0%). Types I and III were relatively easily injured when compared with type II (p = 0.025). Patients in the IG had longer operation times, more blood loss, and more lymph node metastases than the non-IG patients. CONCLUSIONS In most patients, the LGV drains posteriorly to the CHA or anteriorly to the LGA. Gastric surgeons should take great care not to injure the LGV during LG when it is not present on the anterior side of the celiac axis.
