Median arcuate ligament syndrome(MALS)is compression of the celiac trunk by the median arcuate ligament.Median arcuate ligament release is the corner stone for the surgical treatment of MALS.Open surgery,laparoscopic surgery,and robot-assisted surgery have been developed,among which laparoscopic surgery has been proposed as the preferred approach in view of its minimal trauma and short hospital stay.Auxiliary celiac plexus neurolysis could further alleviate the patient's discomfort.Moreover,vascular reconstitution is of vital importance in the case of persistent stenosis in the celiac artery despite of median arcuate ligament decompression.Vascular reconstruction has satisfactory long-term patency rate,while endovascular treatment is less invasive.This article aims to summarize the consensuses and advances and shed light on the surgical treatment of MALS.

Objective: To compare the outcomes of modified Appleby procedure and sub-adventitial divestment technique for locally advanced or borderline resectable pancreatic body cancer. Methods: A total of consecutive 58 patients(33 males and 25 females) who were diagnosed as locally advanced or borderline resectable pancreatic body cancer and underwent distal pancreatectomy at Pancreas Center, First Affiliated Hospital of Nanjing Medical University between September 2013 and May 2019 were retrospectively reviewed. The age(M(IQR)) was 62(9)years(range: 43 to 79 years). Thirty-one patients underwent distal pancreatectomy with celiac axis resection (DP-CAR) and 27 patients underwent distal pancreatectomy with sub-adventitial divestment technique(SDT). Perioperative parameters and follow-up data of these patients were analyzed. Quantitative data were compared with Wilcoxon test while categorical variables were compared with χ² test or Fisher's exact test. Survival results were estimated by the Kaplan-Meier survival method with a Log-rank test. Results: There were no differences in age,gender,body mass index,abdominal symptoms,comorbidity or preoperative serum CA19-9 between two groups(all P>0.05). Obvious preoperative weight loss was more common in the group of SDT(48.1%(13/27) vs. 19.4%(6/31),χ²=5.431,P=0.020). Longer operative time(310(123) minutes vs. 254(137)minutes, Z=2.277,P=0.023),higher rate of combined organ resection(41.9%(13/31) vs. 14.8%(4/27),χ²=5.123,P=0.041) and longer postoperative hospital stay(15(10) days vs. 11(5)days,Z=2.292,P=0.022) were observed in the group of DP-CAR. Moreover,rate of overall morbidities was also higher (71.0%(22/31) vs. 29.6%(8/27),χ²=9.876,P=0.003),implicated by clinically relevant postoperative pancreatic fistula(61.3%(19/31) vs. 29.6%(8/27),χ²=5.814,P=0.020) in the DP-CAR group. Tumor size of the DP-CAR group was bigger(4.9(1.5)cm vs. 4.0(1.2)cm,Z=2.343,P=0.019) but no difference was seen between the DP-CAR group and SDT group in R0+R1(<1 mm) resection rate (84.0%(21/25) vs. 90.0%(18/20),P=0.678) and LNR(12.0(23.0)% vs. 9.0(18.0)%,Z=1.238,P=0.216),as well as median disease free survival(11.7 months vs. 11.4 months,Z=0.019,P=0.892) and median overall survival(16.3 months vs. 13.7 months,Z=0.172,P=0.679). Conclusions: Both DP-CAR and distal pancreatectomy with SDT are relatively safe and feasible for locally advanced or borderline resectable pancreatic body cancer. Compared with arterial resection,SDT may contribute to lower rates of postoperative complications and shorter duration of hospitalization,but no significant benefit is seen in long-term survival.

OBJECTIVETo discuss the change of blood supply pattern in visceral arteries of Stanford B dissection. The visceral arteries include celiac trunk (CA), superior mesenteric artery (SMA) and renal artery (RA).

METHODSBy retrospectively analysing the clinical data of 52 cases with Stanford B dissection, the blood supply pattern of visceral arteries was confirmed by aortography and the changes before and after endovascular repair were compared.

RESULTSAfter repair: the stenosis lesions disappeared in 7 cases supported by true channel completely but one. Twenty-two visceral arteries supported by true and false channel simultaneously recovered true channel chiefly but one. One recovered true channel chiefly and one had no change in 2 visceral arteries supported by false channel completely. Four recovered true channel chiefly and one had no change in 5 visceral arteries without blood support. 88.9% blood support got better and 11.1% blood support had no change in 36 damaged visceral arteries after endovascular repair.

CONCLUSIONBlood support from true and false channel simultaneously is the chief pattern in the injured visceral arteries before repair; Endovascular repair technique is benefit to recovering the blood support of true channel.

INTRODUCTIONKnowledge of anatomical variations of the great vessels of the abdomen, including the coeliac trunk, is important for clinicians planning surgical intervention and radiological imaging. The present study aimed to record the prevalence of variations in the vascular pattern of branches of the coeliac trunk in cadavers.

METHODSA total of 50 properly embalmed and formalin-fixed cadavers from the Indian population were selected for the study. Dissection included surgical incision, followed by mobilisation of the anatomical viscera, to observe and record the branching pattern of the coeliac trunk.

RESULTSThe left gastric, common hepatic and splenic arteries were found to arise from the coeliac trunk in 86% of cadavers. In 76% of cadavers, the origin of the gastric artery was proximal to the bifurcation of the coeliac trunk into the common hepatic and splenic arteries. In one case, all three branches arose directly from the abdominal aorta, and the origin of the splenic artery was 1 cm distal to the origin of the left gastric and common hepatic arteries. In another case, the common hepatic and left gastric arteries arose from the coeliac trunk, and the origin of the splenic artery was 1.5 cm distal to the abdominal aorta.

CONCLUSIONVessel ligation and anastomosis are important in surgical procedures like liver transplantation, and background knowledge of the different vascular patterns of branches of the coeliac trunk is vital. The findings of our study could help to minimise complications related to abdominal surgery, including bleeding and necrosis, and facilitate better and more accurate radiological interpretations.

Behcet's disease has been recognized as a systemic vasculitis characterized by the involvement of multiple organs such as orogenital ulcers, eye lesions including uveitis and optic neuritis, and skin lesions including folliculitis and erythema nodosum. Vascular involvement occurs occasionally and is classified into thrombosis and aneurysm. However, massive gastrointestinal bleeding from arterial aneurysm is a rare manifestation of intestinal Behcet's disease. Recently, we experienced a case of intestinal Behcet's disease presenting with massive gastrointestinal bleeding due to aneurysmal rupture of ileo-colic artery. A 30-year-old male with Behcet's disease was admitted because of massive gastrointestinal bleeding. A large ileo-cecal ulcer was revealed as a bleeding focus on colonoscopic examination. Celiac angiography showed aneurysm and stenosis of ileo-colic artery. After the failure of hemostasis with arterial embolization, ileocecectomy was performed. After the resection hematochezia was completely stopped.

To observe the mid- and long-term result of intentional coverage of celiac artery in thoracic endovascular aortic repair (TEVAR) surgery for aortic dissection.
 Methods: We retrospectively analyzed 21 cases who received TEVAR with celiac artery coverage during the operation. The existence of collaterals between celiac artery (CA) and superior mesenteric artery (SMA) was confirmed by preoperative CT angiography (CTA) or digital substract angiography (DSA) for each patient. We used the stent-graft precisely above the orifice of SMA. Follow-ups were carried out at 2 weeks, 1 month, 3 months, 6 months, 1 year after the operation, and once per year thereafter.
 Results: No signs of visceral artery ischemic syptoms such as liver dysfunction, abdominal pain or distention were observed after the operation. There was no signs of spinal cord ischemia (SCI). Seven cases showed type II endoleak upon completion DSA but stopped automatically within 3 months. CTA in follow-ups showed thrombosis formation in false lumen.
 Conclusion: The intentional coverage of CA during the TEVAR for aortic dissection is safe and effective. The incidence of post-operative SCI or visceral artery ischemia is low. Type II endoleak is a major complication but it can be ceased automatically after medication.

UNLABELLEDOBJECTIVE; To evaluate the clinical value of different CT diagnostic criteria for peripancreatic artery and vein invasion in pancreatic carcinoma through comparison with the findings on surgical exploration.

METHODSOf 72 patients of having suspected pancreatic carcinoma were examined by multiplane spiral CT. Among 43 confirmed by surgical pathology; 15 underwent pancreaticoduodenectomy; 28 were found to have unresectable tumors. The peri-pancreatic major vessels including the superior mesenteric artery, celiac artery, hepatic artery, superior mesenteric vein and portal vein were explored carefully during surgical exploration.

RESULTSThe criteria for peri-pancreatic artery invasion was the presence of one of the following signs: artery embeded in tumor, or more than half of the artery circumference involved by tumor with wall irregularity or stenosis. The sensitivity of the above described criteria was 75.0% (12/16). If the criteria of tumor involvement exceeding half of the vessel circumference were adhered to, the sensitivity was 87.5% (14/16), which was high than the former, but the specificity was lower than that of the former one (90.2% versus 95.1%). The criteria for peri-pancreatic vein invasion was presence of any of the following signs: vein obliteration, more than half of the vein circumference involved by tumor, vein wall irregularity, vein stenosis, tear-drop sign of superior mesenteric artery. The sensitivity of the above described criteria was 92.9% (39/42), higher than that of the criteria that more than half of the vessel circumference was involved by the tumor (69.0%, 29/42), but the specificity of both criteria was the same (97.4%, 37/38).

CONCLUSIONFor assessing peri-pancreatic artery and vein invasion, using the combination of different CT diagnostic criteria has higher accuracy than when using only criteria of more than half of vessel circumference involved by tumor.

OBJECTIVETo investigate the role of MRI in evaluating the peripancreatic vessel invasion and resectability of pancreatic carcinoma based on the comparison of MRI image with surgical exploration, and try to establish the criteria for assessment of the sensitivity, specificity and accuracy of resectability.

METHODSForty-one pancreatic carcinoma patients confirmed by pathology received preoperative plain and contrast enhanced MRI scan, and 37 of them had additional coronal MRA scan. Peripancreatic vessel invasion was preoperatively assessed based on MRI features, and the vessel invasion degree from the uninvolved to the severely involved was divided into 6 grades represented by 1, 2a, 2b, 3a, 3b and 4, respectively. Compared with the findings during the surgery, the sensitivity and specificity of each vessel invasion grade were studied and the receiver operator characteristic curve (ROC) was drawn. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of resectability evaluation based on 2 and 2a degree were calculated respectively. The resectability of involved arteries and veins of grade 2 were also analyzed.

RESULTSOf the 41 patients, 22 had resectable tumor, with 20 curative resection and 2 palliative. Compared with the findings during surgery, seven vessels including three arteries and four veins were not correctly interpreted by MRI. If grade 1,2a,2b,3a and 3b was used as the resectable standard,respectively, the sensitivity to predict the unresectbility was 78.3%, 84.8%, 67.4%, 56.5% and 47.8%, respectively. Receiver operator characteristic curve demonstrated that grade 2a was the optimal critical point. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of grade 2a in predicting the unresectbility were 84.8%, 98.5%, 92.9%, 96.6% and 95.9%.

CONCLUSIONOur data showed that grade 2a (tumor involvement < 2 cm long and < 1/2 circumference of the vessel) may be more sensitive and accurate in predicting the resectability, which may be considered as the line of demarcation between the respectable and unresectable cases in clinical practice.

OBJECTIVETo explore the feasibility, safety and efficacy of intraoperative regional infusion chemotherapy by celiac trunk in advanced gastric cancer patients.

METHODSOne hundred and twenty-six patients with advanced gastric cancer(stageII(-III() were screened from database of Gastrointestinal Surgery Department of Taizhou People's Hospital between January 2008 and December 2010 who underwent R0 resection and D2 lymphadenectomy, received postoperative chemotherapy(XELOX or FOLFOX), and had complete follow-up data. They were divided into infusion chemotherapy group (65 cases) and control group (61 cases) according to regional infusion chemotherapy or not (fluorine 1 000 mg and cisplatin 60 mg). The side effects of chemotherapy, parameters related to the operation, long-term survival and relapse rate were compared between the two groups.

RESULTSThe baseline data between the two groups were comparable(all P>0.05). Postoperative III( and IIII( adverse reaction of chemotherapy was not significantly different between the two groups (P>0.05). The time of postoperative intestinal function recovery [(67.9±14.8) hours vs. (68.9±15.0) hours, t=-0.380, P=0.705), volume of postoperative 1-week drainage [(66.1±17.1) ml vs.(61.9±18.2) ml, t=1.478, P=0.142], recent morbidity of complications[55.4%(36/65) vs. 49.2%(30/61), χ=0.256, P=0.613], and the long-term morbidity of complications [16.9% (11/65) vs. 14.8% (9/61), χ=0.111, P=0.739] were all not significantly different between the two groups. The 3-year survival rate and 3-year relapse-free survival rate in infusion chemotherapy group were significantly higher than those in control group(58.4% vs. 37.7%, χ=5.382, P=0.020; 58.4% vs. 34.4%, χ=6.636, P=0.010).

CONCLUSIONRegional infusion chemotherapy by celiac trunk during operation for advanced gastric cancer patients is safe and feasible, and can reduce the risk of local recurrence and improve survival rate.
