Clinical outcomes after surgical decompression of median arcuate ligament syndrome-An observational study.

BACKGROUND AND OBJECTIVES: Median arcuate ligament syndrome is caused by compression and stenosis of the celiac artery. Incision of the median arcuate ligament improves persistent abdominal symptoms. The study aimed at evaluating the outcomes in patients who underwent median arcuate ligament syndrome decompression using a self-report questionnaire. METHODS: This single-center retrospective study included patients with median arcuate ligament syndrome who underwent decompression surgery between April 2021 and February 2023. The medical records were retrospectively reviewed. RESULTS: Ten patients were included in the study. Laparotomy and laparoscopic surgeries were performed in seven and three patients, respectively. The median operation time was 147 minutes. The median hospitalization period after the operation was seven days. The degrees of celiac artery stenosis before and after surgery were compared and the per cent diameter stenosis did not significantly improve; five of 10 patients (50%) had > 50% stenosis in the celiac artery after the operation. Compared to the baseline, the scores of upper gastrointestinal symptoms significantly improved during the six months' period (p < 0.001). Additionally, we evaluated the influence of post-operative per cent diameter stenosis and divided the patients into two groups (≥ 50% vs, < 50%). The scores of upper gastrointestinal (GI) symptoms in both groups improved significantly from baseline. However, the symptomatic improvement at six months in the post-operative per cent diameter stenosis < 50% group was significantly greater than that in the ≥ 50% group (p = 0.016). The scores of lower gastrointestinal symptoms did not change significantly during the six-month period. CONCLUSION: Decompression surgery for median arcuate ligament syndrome could improve upper gastrointestinal symptoms regardless of the post-operative per cent diameter stenosis.

Periarterial and Sub-adventitial Divestment Along with Triangle Operation and RAMPS for Pancreatic Body Cancer.

BACKGROUND: Locally advanced cancers of the pancreatic body can abut or involve the celiac axis, hepatic artery, or superior mesenteric artery. Recent evidence suggests that these tumors are amenable to surgery after neoadjuvant chemotherapy (Hackert et al., Locally advanced pancreatic cancer: neoadjuvant therapy with FOLFIRINOX results in resectability in 60 % of the patients. Ann Surg 264:457-463, 2016; Rangelova et al., Surgery improves survival after neoadjuvant therapy for borderline and locally advanced pancreatic cancer: a single-institution experience. Ann Surg 273:579-86, 2021). An arterial divestment technique can be used for these cancers to get an R0 clearance, thereby avoiding morbid arterial resections (Miao et al., Arterial divestment instead of resection for locally advanced pancreatic cancer (LAPC). Pancreatology 16:S59, 2016; Habib et al., Periadventitial dissection of the superior mesenteric artery for locally advanced pancreatic cancer: surgical planning with the "halo sign" and "string sign." Surgery 169(5):1026-1031, 2021; Diener et al., Periarterial divestment in pancreatic cancer surgery. Surgery 169(5):1026-31, 2020). Two techniques are described for arterial divestment. In the periarterial divestment technique, the plane of the dissection is between the tumor and the adventitia (Habib et al., Periadventitial dissection of the superior mesenteric artery for locally advanced pancreatic cancer: surgical planning with the "halo sign" and "string sign." Surgery 169(5):1026-1031, 2021; Diener et al., Periarterial divestment in pancreatic cancer surgery. Surgery 169(5):1026-31, 2020). In sub-adventitial dissection, the plane of dissection is between the tunica adventitia and the external elastic lamina (Gao et al., Sub-adventitial divestment technique for resecting artery-involved pancreatic cancer: a retrospective cohort study. Langenbecks Arch Surg 406:691-701, 2021). The TRIANGLE operation also is one of the surgical techniques to achieve R0 resection in locally advanced pancreatic cancer (Hackert et al., The TRIANGLE operation: radical surgery after neoadjuvant treatment for advanced pancreatic cancer: a single-arm observational study. HPB Oxford 19:1001-1007, 2017). This multimedia article aims to demonstrate peri-arterial and sub-adventitial divestment techniques as well as the TRIANGLE operation for a locally advanced cancer of the body of the pancreas. The video also highlights the technique of posterior radical antegrade modular pancreato-splenectomy (RAMPS) together with lymph node clearance. PATIENT AND METHODS: A 57-year-old women was detected to have pancreatic body adenocarcinoma with tumor contact of the artery and superior mesenteric artery. After neoadjuvant chemotherapy, she was planned to undergo surgical resection. RESULTS: The surgical technique consisted of peri-arterial and sub-adventitial divestment, the TRIANGLE operation and RAMPS (Fig. 1). The procedure was performed within 240 min and involved blood loss of 250 mL. After the procedure, pancreatic leak (POPF-B), chyle leak and diarrhea developed, which were managed conservatively. The final histopathology showed residual, viable, moderately differentiated adenocarcinoma (ypT2N1M0) with all resection margins free. CONCLUSION: The surgical technique consisting of peri-arterial and sub-adventitial divestment, the TRIANGLE operation and RAMPS helps in R0 resection of locally advanced pancreatic body cancer without any compromise in oncologic outcomes and offers an alternative surgical approach to morbid arterial resection.

Indications for Multivisceral Transplantation: A Systematic Review.

Consensus remains elusive in the definition and indications of multivisceral transplantation (MVT) within the transplant community. MVT encompasses transplantation of all organs reliant on the celiac artery axis and the superior mesenteric artery in different combinations. Some institutions classify MVT as involving the grafting of the stomach or ascending colon in addition to the jejunoileal complex. MVT indications span a wide spectrum of conditions, including tumors, intestinal dysmotility disorders, and trauma. This systematic review aims to consolidate existing literature on MVT cases and their indications, providing an organizational framework to comprehend the current criteria for MVT.

[A Case of Adenocarcinoma of Pancreatic Head of Liver Disfunction after Pancreaticoduodenectomy with Celiac Artery Stenosis Treated by Urgent Median Arcuate Ligament Release].

This patient visited our hospital for the purpose of detailed examination of prostate cancer in his seventies. Abdominal contrast-enhanced computed tomography(CT)revealed a low-density mass of 2 cm in the pancreatic head. He was diagnosed with pancreatic cancer. Pancreaticoduodenectomy was performed after 2 courses of gemcitabine and S-1 therapy were performed as neoadjuvant chemotherapy. An intraoperative clamp test of the gastroduodenal artery showed that the pulsation of the common hepatic artery and the proper hepatic artery was weak but sufficient, so the gastroduodenal artery was cut and the operation was completed as planned. A blood test on the 1st day after the operation showed elevated levels of AST 537 U/L, ALT 616 U/L, and 7 hours later blood sampling showed further increases in AST 1,455 U/L, ALT 1,314 U/L. After a detailed review of the preoperative CT, celiac artery stenosis due to compression of the arcuate ligament was suspected, and urgent median arcuate ligament release was performed on the same day. Dissection of the arcuate ligament significantly improved the pulsation of the common hepatic artery and proper hepatic artery. Postoperatively, hepatic enzymes improved and ISGPS showed Grade B pancreatic juice leakage, but the patient was discharged from the hospital on the 49th postoperative day without any other complications. He took S-1 as adjuvant chemotherapy, and no signs of recurrence have been observed 9 months after the operation.

Dissection of the Celiac Trunk Is a Mild Disease.

BACKGROUND: The purpose of this study was to assess whether the presence of an aneurysmal or dissecting arterial disease was a risk factor of poor prognosis in patients presenting a dissection of the celiac trunk (CT). METHODS: All patients presenting a CT dissection between January 1, 2014, and June 30, 2022, were included. Patients with a CT dissection due to the extension of an aortic dissection were excluded. Les antécédents familiaux de dissection, de maladie anévrysmale, de maladie athéromateuse ou du tissu conjonctif, la pratique d'une activité physique ou sportive, un effort inhabituel les jours précédant la dissection ainsi qu'un traumatisme étaient recherchés. Family history of dissection, aneurysmal disease, atheromatous or connective tissue disease, physical activity or sport, an unusual effort in the days prior to the dissection and trauma were sought after. Ischemic or aneurysmal complications in the acute phase and the evolution of the dissection were evaluated and compared between patients with an isolated dissection and those presenting an aneurysmal or dissecting arterial disease. RESULTS: 45 patients were included in the study. Twenty-three (51.1%) patients presented with symptomatic CT dissection, and 22 (48.9%) with asymptomatic CT dissection. All the patients initially had medical management alone. The mean follow-up was 32 ± 25 months and all patients were asymptomatic at the time last news. 24 (53.3%) presented an isolated CT dissection, and 21 (46.7%) a CT dissection associated with aneurysmal or dissecting arterial disease. There was no significant difference between patients with an isolated CT dissection and those with an associated dissecting or aneurysmal pathology. CONCLUSIONS: CT dissection is a stable disease in the midterm, which makes it a mild arterial pathology, with or without aneurysmal or dissecting anomalies in another territory. The mechanical stress exerted on the CT by the arcuate ligament could be responsible for parietal trauma and favor the occurrence of a CT dissection.

Robotic Pancreaticoduodenectomy with 'SMA-First Approach (Posterior and Right Medial)' and 'Triangle Operation'.

BACKGROUND: Notable improvements in pancreatic cancer surgery have been due to utilization of the superior mesenteric artery (SMA)-first approach1 and triangle operation (clearance of triangle tissue between origin of SMA and celiac artery).2 The SMA-first approach was originally defined to assess resectability before taking the irreversible surgical steps. However, in the present era, resectability is judged by the preoperative radiology, and the benefit of the SMA-first approach is by improving the R0 resection rate and reducing blood loss. The basic principle is to identify the SMA at its origin and in the distal part, to guide the plane of uncinate dissection. This video demonstrates the combination of the posterior and right medial SMA-first approach along with triangle clearance during robotic pancreaticoduodenectomy (RPD). METHODS: The technique consisted of early dissection of SMA from the posterior aspect, by performing a Kocher maneuver using the 'posterior SMA-first approach'. The origin of the celiac artery, along with the SMA, was defined early in the surgery. During uncinate process dissection, the 'right/medial uncinate approach' was used to approach the SMA. 'Level 3 systematic mesopancreatic dissection' was performed along the SMA,3 culminating in the 'triangle operation'.2 RESULTS: The procedure was performed within 600 min, with a blood loss of 150 mL and no intraoperative or postoperative complications. The final histopathology report showed a moderately differentiated adenocarcinoma (pT2, pN2), with all resection margins free. CONCLUSION: The standardized technique of the SMA-first approach and triangle clearance during RPD is demonstrated in the video. Prospective studies should further evaluate the benefits of this procedure.

Intraoperative assessment of blood flow using transabdominal ultrasound during laparoscopic surgery of celiac artery compression syndrome.

Surgical treatment of celiac artery (CA) compression syndrome (CACS) is to release the median arcuate ligament (MAL) by removing the abdominal nerve plexus surrounding CA. In laparoscopic surgery of CACS, objective intraoperative assessment of blood flow in CA is highly desirable. We herein demonstrate a case of laparoscopic surgery of CACS with use of intraoperative transabdominal ultrasound. A 52-year-old woman was presented with epigastric pain and vomiting after eating. Contrast-enhanced computed tomography demonstrated significant stenosis at the origin of CA. Doppler study of CA was also performed, and she was diagnosed as CACS. Laparoscopic surgery was performed, and the MAL was divided. And then, Doppler study using intraoperative transabdominal ultrasound confirmed the successful decompression of CA. This patient was discharged on postoperative day 11, and her symptoms was improved. Intraoperative assessment of blood flow in CA using transabdominal ultrasound was a simple and useful method for laparoscopic surgery of CACS.

Median arcuate ligament release at the time of pancreaticoduodenectomy or total pancreatectomy.

BACKGROUND: Celiac artery compression can complicate the performance of pancreaticoduodenectomy or total pancreatectomy due to the need for ligation of the gastroduodenal artery. Median arcuate ligament release restores normal arterial flow to the liver, spleen, and stomach and may avoid complications related to poor perfusion of the foregut. METHODS: All patients who underwent median arcuate ligament release for celiac artery compression at the time of pancreatectomy between 2009 and 2023 were reviewed. Pre- and postoperative computed tomography was used to categorize celiac artery compression by the extent of compression (types A [<50%], B [50%-80%], and C [>80%]). RESULTS: Of 695 patients who underwent pancreatectomy, 22 (3%) had celiac artery compression, and a majority (17) were identified on preoperative imaging. Median celiac artery compression was 52% (interquartile range = 18); 8 (36%) patients had type A and 14 (64%) had type B compression with a median celiac artery compression of 39% (interquartile range = 18) and 59% (interquartile range = 14), respectively (P < .001). Postoperative imaging was available for 20 (90%) patients, and a reduction in the median celiac artery compression occurred in all patients: type A, 14%, and type B, 31%. Complications included 1 (5%) death after hospital discharge, 1 (5%) pancreatic fistula, 1 (5%) delayed gastric emptying, and 4 (18%) readmissions. No patient had evidence of a biliary leak or liver dysfunction. CONCLUSION: Preoperative computed tomography allows accurate identification of celiac artery compression. Ligation of the gastroduodenal artery during pancreaticoduodenectomy or total pancreatectomy in the setting of celiac artery compression requires median arcuate ligament release to restore normal arterial flow to the foregut and avoid preventable complications.

Use of selective visceral angiography in surgical strategy planning for celiac artery aneurysm in the celiacomesenteric trunk.

BACKGROUND: The celiacomesenteric trunk (CMT) is a common duct of the celiac artery (CA) and the superior mesenteric artery originating from the aorta, which is an uncommon anatomical variant of visceral artery circulation. Because of the variety of visceral circulation in those with CMT, the visceral circulation associated with each branch should be evaluated prior to surgical treatment of visceral artery aneurysm in the CMT. CASE PRESENTATION: A 64-year-old woman was diagnosed with a CA aneurysm in the CMT. Aneurysmectomy of the aneurysm was performed successfully. On preoperative selective visceral angiography, the CA was seen to bifurcate into the common hepatic and splenic artery. The left gastric artery was directly isolated from the aorta and perfused to the common hepatic and splenic artery through collateral circulation. These findings showed that celiac artery embolization is anatomically feasible, even in cases of celiac artery aneurysm rupture. CONCLUSIONS: Selective visceral angiography can contribute to surgical strategy planning for CA aneurysm with CMT.

Laparoscopic Median Arcuate Ligament Release: Surgical Technique and Clinical Outcomes.

BACKGROUND: Median arcuate ligament syndrome (MALS) is characterized by a constellation of symptoms related to the compression of the celiac artery trunk. Laparoscopic release of the ligament has demonstrated its effectiveness in alleviating these symptoms while showing lower postoperative complication rates, reduced hospital stays, and improved clinical outcomes. This study describes a single institution's experience with this procedure and reports on the preoperative assessment, surgical technique, and clinical outcomes of patients with MALS. METHODS: We performed a retrospective chart review of all patients who underwent a primary laparoscopic MAL release (MALR) at a single high-volume academic institution from June 2021 to July 2023. Patient demographics, preoperative assessment, postoperative complications, and resolution of preoperative symptoms data were collected. RESULTS: A total of 30 patients underwent laparoscopic MALR, with 76.7% being female and a mean age of 33.4±16.3 years. The most common presenting symptom was postprandial epigastric pain (100%), followed by abdominal pain and nausea (83.3%), among others. The preoperative evaluation for all patients included a duplex mesenteric doppler and CT angiogram during inspiration and expiration and 3D reconstruction. Successful laparoscopic decompression of the celiac artery was achieved in 96.6% of cases, with only one conversion to an open procedure. There was only one reported early (<30 d postoperatively) complication with no subsequent late complications or mortality. None of the patients required reintervention or reoperation. Only 1 patient required postoperative celiac plexus/splanchnic block injection to alleviate pain. CONCLUSIONS: MALS can be effectively and safely managed using a laparoscopic approach when performed by an experienced minimally invasive surgeon. Further studies with longer follow-ups are needed to confirm the long-term effectiveness of this technique.

Clinical Outcomes after Median Arcuate Ligament Release in Patients Responsive to Celiac Plexus Block.

PURPOSE: To determine if symptom relief with celiac plexus block (CPB) is associated with favorable clinical outcomes after median arcuate ligament release (MALR) surgery. MATERIALS AND METHODS: A retrospective review was performed from January 2000 to December 2021. Fifty-seven patients (42 women, 15 men; mean age, 43 years [range, 18-84 years]) with clinical and radiographic features suggestive of median arcuate ligament syndrome (MALS) underwent computed tomography (CT)-guided percutaneous CPB for suspected MALS. Clinical outcomes of CPB and MALR surgery were correlated. Adverse events were classified according to the Society of Interventional Radiology (SIR) guidelines. RESULTS: CT-guided percutaneous CPB was successfully performed in all 57 (100%) patients with suspected MALS. A cohort of 38 (67%) patients showed clinical improvement with CPB. A subset of 28 (74%) patients in this group subsequently underwent open MALR surgery; 27 (96%) responders to CPB showed favorable clinical outcomes with surgery. There was 1 (4%) CPB-related mild adverse event. There were no moderate, severe, or life-threatening adverse events. CONCLUSIONS: Patients who responded to CPB were selected to undergo surgery, and 96% of them improved after surgery.

Pancreaticoduodenal Artery Aneurysm Complicated by Median Arcuate Ligament Syndrome.

PURPOSE: To highlight median arcuate ligament syndrome as a potential cause for celiac artery stenosis and pancreaticoduodenal artery aneurysm, and describe treatment options in this setting. CASE REPORT: A 63-year-old male presented with a pancreaticoduodenal artery aneurysm and concomitant celiac artery stenosis that was treated with celiac artery stenting and aneurysm coiling. He subsequently developed stent fracture and celiac artery occlusion secondary to previously unrecognized median arcuate ligament syndrome causing reperfusion of the aneurysm. This was treated with open median arcuate ligament release and aorta to common hepatic artery bypass with good clinical result and stable 20-month surveillance imaging. CONCLUSION: It is critical to recognize median arcuate ligament syndrome as a cause of celiac artery stenosis in the setting of pancreaticoduodenal artery aneurysm given the high risk of failure of endovascular stenting. Open aorto-hepatic artery bypass and endovascular aneurysm coiling should be the preferred approach in these patients.

The anatomical relationship between the celiac artery and the median arch ligament in degenerative spinal surgery.

BACKGROUND: This study aimed to characterize the anatomical relationship between the spine, the celiac artery (CA), and the median arcuate ligament using preoperative contrast-enhanced computed tomography (CT) images of patients with spinal deformity who underwent surgical correction. METHODS: This retrospective study included 81 consecutive patients (34 males, 47 females; average age: 70.2 years). The spinal level at which the CA originated, the diameter, extent of stenosis, and calcification were determined using CT sagittal images. Patients were divided into two groups: CA stenosis group and non-stenosis group. Factors associated with stenosis were examined. RESULTS: CA stenosis was observed in 17 (21%) patients. CA stenosis group had significantly higher body mass index (24.9 ± 3.9 vs. 22.7 ± 3.7, p = 0.03). In the CA stenosis group, J-type CA (upward angling of the course by more than 90° immediately after descending) was more frequently observed (64.7% vs. 18.8%, p < 0.001). The CA stenosis group had lower pelvic tilt (18.6 ± 6.7 vs. 25.1 ± 9.9, p = 0.02) than non-stenosis group. CONCLUSIONS: High BMI, J-type, and shorter distance between CA and MAL were risk factors for CA stenosis in this study. Patients with high BMI undergoing fixation of multiple intervertebral corrective fusions at the thoracolumbar junction should undergo preoperative CT evaluation of the anatomy of CA to assess the poteitial risk of celiac artery compression syndrome.

A gastroduodenal artery that branched from the celiac artery in gastrectomy: A rare case of an anatomical variant.

Understanding anatomical anomalies of the branch of the celiac artery for safe gastrectomy is important. We report a case of laparoscopic distal gastrectomy with D1+ lymph node dissection for early gastric cancer with a vascular anatomical anomaly of the celiac artery. A 45-year-old woman was referred to our hospital because of early gastric cancer. Computed tomography showed an anatomical variation of the gastroduodenal artery, which branched from the celiac artery. The celiac artery also branched into the left gastric artery, the splenic artery, and the common hepatic artery. Preoperative understanding of an unusual branch of the celiac artery enabled a safe laparoscopic surgery. There were no postoperative complications. The Adachi classification or Michel classification is used for an anatomical anomaly of the celiac artery, but to the best of our knowledge, this case has not been previously classified and is the first reported case.

First description of a histopathologic grading system and relationship to outcomes after robotic median arcuate ligament release with celiac ganglionectomy and lymphadenectomy.

BACKGROUND: Two dominating theories regarding median arcuate ligament syndrome include vascular and neurogenic etiologies from celiac artery and ganglion compression, respectively. Celiac ganglionectomy is not routine during surgery, and specimens are rarely excised; therefore, the extent of nerve involvement and histopathology are unknown. Our study aims to characterize histopathologic findings in median arcuate ligament syndrome, establish a histopathologic grading system, and correlate with clinical outcomes. METHODS: Robotic median arcuate ligament release, celiac ganglionectomy, and lymphadenectomy were performed with specimens excised and stained using hematoxylin & eosin, trichrome, and S100. Neurofibrosis, adiposity, and reactive changes were described, a grading scale was developed, and results were analyzed with clinical outcomes. RESULTS: Fifty-four patients were evaluated, of whom 36 met inclusion criteria (81% female, 34.9 [25.9-47.5] years, body mass index 23.5 [19.6-28.1] kg/m2). Histopathologic evaluation revealed fibrosis (hematoxylin & eosin and trichrome median score 1.5 [0-2.5]), reactive lymphadenopathy (89%), intraparenchymal nerves (31%), and lipogranulomas (31%). Greater fibrosis was associated with a lack of preoperative celiac plexus block relief (100% vs. 30%, P = .044) and lower postoperative celiac artery velocities (198 vs 323 cm/s, P = .02). Intraparenchymal nerves were associated with greater decreases in pre to postoperative velocities (161 vs 84 cm/s, P = .037). Symptoms improved in 28 patients (78%). CONCLUSION: We developed the first histopathologic grading system and identified unique findings of intraparenchymal nerves and lipogranulomas. Histopathologic abnormalities were associated with objective improvement and symptomatic relief postoperatively. These findings support nerve compression and inflammation as predominant contributors to median arcuate ligament syndrome pain, celiac ganglia resection to treat symptoms, and continued histopathologic analysis to better elucidate median arcuate ligament syndrome etiology.

Celiac trunk stenosis by median arcuate ligament in orthotopic liver transplantation: a potential hidden foe to the biliary tree.

BACKGROUND: Celiac trunk compression by the median arcuate ligament (MAL) increases the risk of ischemic complications following gastrointestinal surgical procedures. Previous studies suggest increased risk of hepatic artery thrombosis (HAT) in orthotopic liver transplant (OLT) recipients. The aim of this study is to investigate the impact of untreated MAL compression (MAL-C) on biliary complications in OLT. METHODS: Contrast-enhanced imaging was used to classify celiac trunk stenosis by MAL-C. Medical records were reviewed to extract pre-transplant, transplant and post-transplant data. Patients were divided into two groups: no MAL compression (nMAL-C) and MAL-C. The primary endpoint was biliary complications. Secondary endpoints were HAT and graft survival. RESULTS: 305 OLT were performed from 2010 to 2021, of which 219 were included for analysis: 185 (84.5%) patients without and 34 (15.5%) with MAL-C. The incidence of HAT was 5.9% in both groups. Biliary complications were more common in the MAL-C group (35.3% vs. 17.8%, p = 0.035). Graft survival was decreased in patients with MAL-C (p = 0.035). CONCLUSIONS: MAL-C of the celiac trunk was associated with increased risk of biliary complications and inferior graft survival in OLT patients. These findings highlight the importance of preoperative screening and treatment of MAL in this population.

[Diagnosis and treatment of Dunbar syndrome]. / Diagnostik und Therapie des Dunbar-Syndroms.

The rare Dunbar syndrome or medial arcuate ligament syndrome (MALS) is defined as compression of the celiac trunk and/or ganglion by the medial arcuate ligament. It is often diagnosed after patients have suffered for a long time and is characterized by intermittent food-related pain, nausea, and unexplained weight loss. After exclusion of other causes of the above symptoms by gastroscopy, colonoscopy, CT, or MRI, the gold standard for diagnosis is dynamic color-coded duplex sonography, which may be supplemented by CT or MR angiography. The treatment of choice is a laparoscopic division of the arcuate ligament at the celiac trunk, although percutaneous transluminal angioplasty (PTA) with stent implantation may be performed in cases of postoperative persistence of symptoms or recurrent stenosis. Since symptoms persist postoperatively in up to 50% of cases, strict indication and complete diagnosis in designated centers are of great importance for successful treatment.

Prognostic impact of the distance from the root of splenic artery to tumor in the patients with pancreatic body or tail cancer.

BACKGROUND: The impact of the distance from the root of splenic artery to tumor (DST) on the prognosis and optimal surgical procedures in the patients with pancreatic body/tail cancer has been unclear. METHODS: We retrospectively analyzed 94 patients who underwent distal pancreatectomy (DP) and 17 patients who underwent DP with celiac axis resection (DP-CAR) between 2008 and 2018. RESULTS: The 111 patients were assigned by DST length (in mm) as DST = 0: n = 14, 0

A Case Series of Median Arcuate Ligament Syndrome With Varied Presentations.

Median arcuate ligament syndrome (MALS) is characterized by the constriction of the celiac trunk caused by fibrous connections originating from the median arcuate ligament (MAL) and diaphragmatic crura. It presents with symptoms often leading to misdiagnosis. In this study, we present three cases of MALS, with distinct manifestations. These cases were diagnosed through comprehensive investigations and managed successfully using laparoscopic decompression. The diagnosis of MALS poses challenges due to its variable presentations and overlap with other conditions. Diagnostic imaging techniques such as Doppler ultrasound, computed tomography (CT) scans and angiography play a role in confirming the diagnosis. Laparoscopic decompression has proven to be a treatment option that relieves symptoms and restores blood flow. This series highlights the importance of considering MALS as a cause for abdominal pain cases. Early detection and the use of diagnostic techniques can result in favorable outcomes.
