Project description:PurposeThe purpose of this study is to evaluate the efficacy of laparoscopic pancreaticoduodenectomy (LPD) with superior mesenteric artery (SMA) left posterior first approach and circumferential lymphadenectomy with total meso-pancreas (MP) dissection for periampullary malignancies.Methods31 patients who underwent LPD with left posterior SMA first-approach and circumferential lymphadenectomy with total MP dissection between September 2021 and September 2023. General characteristics, operative techniques, short-term outcomes and pathological results were prospectively evaluated.ResultsThe mean operation time and SMA first-approach time were 441.9 ± 73.7 min and 99.9 ± 27.7 min, respectively. The median intraoperative blood loss was 143 ml (range: 50-1500 ml). The median number of total LNs and left-sided SMA LNs harvested were 32,7 ± 13 (16-74) and 7,4 ± 6 (range: 3-30), respectively. The rate of metastatic left-sided SMA LNs and meso-pancreas were 25.8% and 22.6%, respectively. 22.6% of patients had pancreatic fistula, but mostly in grade A, with only one case that required conversion. Only one case developed postoperative refractory diarrhea. The mean postoperative hospital stay was 14.1 days. No 90-day mortality was reported.ConclusionLPD with left posterior SMA first-approach and circumferential lymphadenectomy with total MP dissection was safe and effective with favorable short-term outcomes.

Project description:BackgroundThe superior mesenteric artery (SMA)-first approach for pancreatic cancer (PC) is common surgical technique in pancreaticoduodenectomy. To date, few studies have reported SMA-first approach in robot-assisted pancreaticoduodenectomy (RPD). Herein, we present the anterior SMA-first approach for PC during RPD.Patient and methodA 75-year-old man with resectable PC underwent RPD after neoadjuvant chemotherapy. As pancreatic head tumor contacted with the superior mesenteric vein (SMV), the anterior SMA approach was applied. After the mesenteric Kocher maneuver, the jejunum was divided and the left side of the SMA was dissected. Subsequently, the anterior plane of the SMA was dissected. Following the division of branches from the mesenteric vessels, the SMA was taped, and the circumferential dissection around the SMA was performed to detach the pancreatic neck from the SMA completely. Finally, the dissection between the SMV and the tumor was performed under vascular control to remove the specimen.ConclusionsThe anterior SMA-first approach can be optional in patients with PC undergoing RPD. This unique approach allows for the circumferential dissection around the SMA during RPD.

Project description:IntroductionTotal laparoscopic pancreaticoduodenectomy (tLPD) for cancer of the Vater remains a challenging procedure. Recently, several meta-analyses showed the superior aspects of "superior mesenteric artery (SMA)-first approach," "systematic mesopancreas dissection," and "circumferential lymphadenectomy around SMA" in increasing R0 resection rate and reducing postoperative complications including pancreatic fistula and bleeding as well as improving overall survival particularly.Case presentationOur patient is a 70-year-old female with a no special medical history, recruited because of jaundice. She was referred for pancreaticoduodenectomy because of a 10-mm-sized mass in distal bile duct referred to as Vater's tumor. We used 5 trocars, and the patient was placed in a Trendelenburg position. The transverse colon was lifted, the first loop of the jejunum was pulled to the left, and lymph node groups 14th and 15th were removed en bloc and then exposed the SMA from the anterior to the left posterior side from the caudal side to the origin. The first jejunal vessels and the posterior inferior pancreaticoduodenal artery were ligated as well as the extensive mobility of the duodenum and head of the pancreas from the left side. The systematic mesopancreas dissection from the right site of the SMA will be easily and conveniently done afterwards. Histopathological examination of ypT2N1 indicated that 1 of the 22 lymph nodes was positive, which was 1 of 7 LN no. 14. Pathological results showed a Vater adenocarcinoma with all margins being negative.ConclusionsThis technique was safe and effective to perform precise level 2 mesopancreas dissection and complete lymphadenectomy around SMA without dissection of pl-SMA in laparoscopic field.

Project description:The concept of the superior mesenteric artery (SMA)-first approach has been widely accepted in pancreatoduodenectomy. However, few studies have reported surgical approaches to the SMA in robotic pancreatoduodenectomy (RPD). Herein, we present our surgical strategies to dissect around the SMA in RPD. Among the various approaches, our standard protocol for RPD included the right approach to the SMA, which can result in complete tumor resection in most cases. In patients with malignant diseases requiring lymphadenectomy around the SMA, we developed a novel approach by combining the left and right approaches in RPD. Using this approach, circumferential dissection around the SMA can be achieved through both the left and right sides. This approach can also be helpful in patients with obesity or intra-abdominal adhesions. The present study summarizes the advantages and disadvantages of both the approaches during RPD. To perform RPD safely, surgeons should understand the different surgical approaches and select the best approach or a combination of different approaches, depending on demographic, anatomical, and oncological factors.

Project description:Major vascular injuries during robotic renal surgery are rare, but the close proximity of the superior mesenteric artery (SMA) to the left renal artery means that it is liable to iatrogenic injury with potentially catastrophic implications. In this review, we present a case of accidental SMA ligation during a robot-assisted laparoscopic nephrectomy for a 12-cm upper pole renal mass. Prompt recognition and early vascular surgical assistance with conversion to open surgery allowed a primary vascular anastomosis to be made. A computed tomography angiogram at 6 wk was normal. On review of the imaging, the left renal artery take-off was higher than the SMA, which represents an anatomical variant and may have contributed to the injury. The risk of accidental SMA ligation is highest in left-sided tumours and in larger medial tumours that lead to significant distortion of the anatomy. The anatomy of the renal artery can also vary greatly. Surgeons must be knowledgeable of common variations and meticulously review preoperative imaging for the number and course of renal vessels as well as the location of the SMA. In cases of significant bleeding, rapid conversion to open surgery and urgent vascular consultation are critical.Patient summaryIn this article, we describe an accidental injury to a major blood vessel (the superior mesenteric artery) during a left robotic radical nephrectomy (kidney removal) for a tumour. We discuss the anatomical relationships of the blood vessels of the small bowel and kidneys, and how to anticipate, recognise, and manage such accidental injuries.

Project description:Injury to the superior mesenteric artery (SMA) is a rare, underreported, and potentially devastating complication. This study aims to propose a systematic workup to describe how to prevent and manage SMA injury in a standardized stepwise manner. Three different instances of intraoperative injury to the SMA are described in an accompanying video. All three occurred when the SMA was misidentified as the left renal artery during left robotic radical nephrectomy. In the first case, the SMA was mistakenly identified as the renal artery, but after further dissection, the real renal artery was identified and SMA injury was prevented. In the second case, the SMA was clipped and the real left renal artery was subsequently identified, requiring clip removal. In the third case, the SMA was clipped and completely transected, requiring prompt repair by vascular surgery with a successful outcome. This study aims to propose a systematic workup to describe how to prevent and manage SMA injury in a standardized stepwise manner. The proper anatomic recognition of the SMA may prevent its injury. Intraoperative SMA injury should be promptly identified and repaired to avoid its devastating consequences.

Project description:BackgroundMesenteric ischaemia is often a manifestation of severe vascular disease involving the superior mesenteric artery (SMA). Endovascular revascularization is challenging in a chronic total occlusion (CTO) of SMA.Case presentationA-73-year-old male patient was referred to our hospital because of a 2-year history of post prandial abdominal angina. Computed tomography (CT) images revealed a heavily calcified CTO in the ostium of SMA and three-dimensional CT (3D-CT) detected pancreaticoduodenal arcade with filling from the celiac artery. Then, endovascular procedure was attempted; however, angiography did not show the collateral route suitable for transcollateral approach. As demonstrated on the CT, we were successful in passing a guidewire through the SMA-CTO via the celiac trunk transcollateral route. After pull-through of the guidewire, two balloon-expandable stents were deployed in the ostium of SMA. During 3 months after stent implantation, the patient had no further episodes of abdominal angina on dual-anti-platelet therapy.ConclusionWe demonstrate a case of a heavily calcified SMA occlusion successfully treated with endovascular stenting employing a transcollateral approach, guided by 3D-CT.

Project description:BackgroundAchieving margin negative resection is a significant determinant of outcome in pancreatic adenocarcinoma (PDA). However, because of the fibrotic nature of PDA, it can be difficult to discriminate fibrosis from active disease intra-operatively. We sought to determine if post-hoc video review of robotic pancreatico-duodenectomy (RPD) could predict the portal/superior mesenteric vein (PV/SMV) margin status on final pathology.MethodsExperienced pancreatic surgeons, blinded to patient and operative variables, reviewed the PV/SMV margin for available RPD videos of consecutive PDA patients from 9/2012 through 6/2017.Results107 RPD videos were reviewed. Of 76 patients (71%) predicted to have a negative vein margin on video review, 20 patients (26%) had a pathologic positive margin. 25 of 31 patients (81%) predicted to have positive margin on video review were positive on pathology. The specificity of video prediction was 90.3% with a sensitivity of 55.6% and an accuracy of 75.7%.ConclusionPost-hoc video review prediction is unable to reliably predict a positive (R1) margin at the portal vein/SMV, suggesting that intra-operative clinical assessment may be suboptimal in determining the need for more extensive resections.

Project description:Backgrounds/aimsA superior mesenteric artery first approach (SFA) technique can improve the complete resection rate. It can be used to determine whether an operation can be performed by invading the superior mesenteric artery before performing a pancreatic transection in patients with pancreatic ductal adenocarcinoma (PDAC). The aim of this study was to compare perioperative outcomes between laparoscopic and open SFA for PDAC.MethodsBetween January 2017 and August 2019, consecutive patients who underwent laparoscopic and open pancreaticoduodenectomy (PD) for PDAC using SFA procedures were included and compared between laparoscopic and open procedures.ResultsFourteen and 83 patients underwent laparoscopic and open surgeries, respectively. In perioperative outcomes, there were no significant differences in the amount of intraoperative blood loss or transfusion rate between the two groups. In the laparoscopic group, the operation time was longer with less patients showing wound infection. R0 resection rate and the number of retrieved lymph nodes showed no significant difference. The average time to adjuvant chemotherapy was longer in the open group. There was no significant difference in the mean survival time or the recurrence free period.ConclusionsPatients who underwent laparoscopic PD using SFA showed perioperative outcomes comparable compared to those of patients who underwent open procedures performed by experienced surgeons.
