Furthermore, the development and rupture of pancreaticoduodenal artery aneurysms pose a potentially fatal risk. Median arcuate ligament release (MALR) is useful in the treatment of MALS, with most procedures performed laparoscopically. However, detailed descriptions of laparoscopic MALR (lap-MALR) procedures are rare. In this study, we performed lap-MALR via an anterior approach with dissection of the right lateral wall of the celiac artery (CA). For optimal visualization of the right side of the CA, the right branch of the inferior phrenic artery was divided. We believe that this procedure allows the MAL to be released within a sufficient surgical field and without excess or deficiency. Here, we present the details of six patients who underwent lap-MALR for varying indications; three for pancreaticoduodenal artery aneurysms due to CA obstruction (unruptured, <i>n</i> = 1; ruptured, <i>n</i> = 2), two cases prior to hepato-biliary-pancreatic surgery, and one symptomatic case. In all cases, lap-MALR was performed as described above, and the CA stenosis was successfully released.

Predictors were identified using logistic regression analysis of preoperative evaluable factors. The cutoff values for continuous variables were determined based on a minimum p‐value approach (model 1) or the value that maximized the rate of 5‐y RFS survivors (model 2).Fifty‐one patients (16.1%) achieved a 5‐y RFS. A tumor size ≤23 mm, the absence of serosal invasion on computed tomography (CT), and Neutrophil‐to‐Lymphocyte Ratio <1.0, were significantly associated with the 5‐y RFS in model 1. A Prognostic Nutritional Index ≥58 and the absence of serosal invasion and extrapancreatic nerve plexus invasion on CT were significantly associated with 5‐y RFS in model 2. Only six (11.8%, model 1) and four (7.8%, model 2) patients had all three prognostic factors, and their 5‐y RFS rates were 83.3% and 100%, respectively.A modest number of patients who underwent upfront surgery achieved 5‐y RFS, but only ~10% of them could be identified preoperatively. Based on these results, almost all R‐PC patients are forced to undergo neoadjuvant treatment in daily practice.","PeriodicalId":8030,"journal":{"name":"Annals of Gastroenterological Surgery","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141348301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
