Celiac artery stenosis presents significant risks in pancreatoduodenectomy (PD), including elevated incidences of postoperative hepatic ischemia and clinically relevant pancreatic fistulae. Addressing this stenosis preoperatively is crucial to avoid complication. While stenosis predominantly arises from vasculopathy, managed with stenting, median arcuate ligament syndrome (MALS) is an atypical cause characterized by the median arcuate ligament's extrinsic compression of the celiac artery. Pre-PD surgical release of this ligament has demonstrated nearly 90% success rate in resolving ischemic complications. The celiac axis can be decompressed through open or minimally invasive techniques. Robotic-assisted celiac artery decompression is an attractive approach due to superior visualization and enhanced dexterity, which facilitate the complex dissection required at the diaphragmatic hiatus. The patient is a 49-year-old male diagnosed with pancreatic adenocarcinoma, who also exhibited severe celiac axis stenosis on preoperative imaging. Median arcuate ligament release prior to PD was pivotal in preventing hepatic ischemia consequent to the ligation of the gastroduodenal artery during PD and in re-establishing normal arterial flow to the upper gastrointestinal tract, thereby circumventing otherwise preventable complications. The patient underwent an uneventful robotic PD following the median arcuate ligament release. Robotic-assisted median arcuate ligament release prior to pancreatoduodenectomy is a safe and effective technique for decompression of celiac axis stenosis. This procedure facilitates meticulous dissection while minimizing postoperative complications and helps to circumvent otherwise preventable outcomes.
腹腔干狭窄在胰十二指肠切除术(PD)中存在重大风险,包括术后肝缺血和具有临床意义的胰瘘发生率升高。术前处理这种狭窄对于避免并发症至关重要。虽然狭窄主要由血管病变引起,通过支架置入进行处理,但正中弓状韧带综合征(MALS)是一种非典型病因,其特征是正中弓状韧带对腹腔干的外部压迫。PD术前对该韧带进行手术松解已证明在解决缺血性并发症方面成功率近90%。腹腔干可通过开放或微创技术进行减压。机器人辅助腹腔干减压是一种有吸引力的方法,因为其视野更佳且灵活性增强,这有利于在膈裂孔处进行复杂的解剖。该患者为一名49岁男性,诊断为胰腺腺癌,术前影像学检查还显示存在严重的腹腔干狭窄。PD术前进行正中弓状韧带松解对于预防PD期间胃十二指肠动脉结扎导致的肝缺血以及恢复上消化道正常动脉血流至关重要,从而避免了原本可预防的并发症。在正中弓状韧带松解后,患者顺利接受了机器人辅助PD手术。胰十二指肠切除术前行机器人辅助正中弓状韧带松解是一种安全有效的腹腔干狭窄减压技术。该手术有助于精细解剖,同时将术后并发症降至最低,并有助于避免原本可预防的后果。
