Background And Aim: Superior mesenteric artery (SMA) first approach was a new improvement for pancreaticoduodenectomy (PD), but there is no evidence whether this approach is advantageous to PD. This meta-analysis aimed to determine the effects of the superior mesenteric artery (SMA) first approach on outcomes of pancreaticoduodenectomy (PD).
Methods: Literature searches were conducted on PubMed, The Cochrane Library, EMBASE, Web of Science, Clinical Trials Registry and China Biology Medicine disc. We completed a meta-analysis of the SMA first approach in PD, assessing overall survival, R0 resection, blood loss, postoperative complications, operation time and postoperative stay. The odds ratios and weighted mean differences with 95% confidence intervals (CIs) were pooled.
Results: Eighteen studies comprising 1483 participants were included. Patients who received SMA-PD had significantly lower overall complication rate (OR 0.62, 95% CI 0.47 to 0.81, P = 0.001) and less blood loss (WMD -264.84, 95% CI -336.1 to -193.58, P < 0.001). The obviously increased R0 resection rate (OR 2.92, 95% CI 1.72 to 4.96, P < 0.001) and 3-year OS (OR 2.15, 95% CI 1.34 to 3.43, P = 0.001) were found in the SMA-PD group.
Conclusion: The SMA-PD group had better clinical outcomes, particularly in long-term survival of pancreatic cancer patients; furthermore, the patients acquired superior clinical efficacy via the posterior approach in SMA-PD.

Aim: Complete mesocolic excision (CME) is an oncologically driven technique for treating right colon cancer. While laparoscopic CME is technically demanding and has been associated with more complications, the robotic approach might reduce morbidity. The aim of this study was to assess the safety of stepwise implementation of robotic CME.

In right-sided colon cancer surgery, lymph node dissection around the superior mesenteric artery is necessary but technically challenging. Here we introduce the concept of "outermost layer-oriented robotic surgery" to improve the safety, efficacy, and reproducibility of superior mesenteric artery nodal dissection. In this procedure, the thin, loose connective tissue layer between the autonomic nerve sheath of the superior mesenteric artery and adipose tissue bearing lymph nodes, termed "the outermost layer of the autonomic nerve," is dissected.

This was a case report and literature review, aimed to strengthen the understanding and therapy of mycoplasma pneumoniae (MP) pneumonia combined with cold agglutinin disease and pulmonary embolism in children. A 7-year-old boy was taken to the hospital with fever for 7 days, cough for 5 days, and recurrent cyanosis at the extremities of one day duration. Pulmonary artery computed tomography angiography (CTA) showed pulmonary embolism, double pneumonia, and pleural effusion.

Introduction: The duodeno-pancreatic region is a highly vascularized area. The superior and posterior pancreaticoduodenal artery is a vessel primarily originating from the gastroduodenal artery. It exhibits rare anatomical variations, such as its emergence from the right branch of the hepatic artery, which we fortuitously identified during a cadaver dissection.

Background: Splanchnic vein thrombosis (SpVT) occurs in 17%-23 % of acute pancreatitis cases. Serious sequelae include hepatic and bowel ischaemia. However, management with therapeutic anticoagulation remains controversial due to potential bleeding risk.
