Background/objective: To investigate the feasibility of three-dimensional (3D) reconstruction with an interactive Hisense computer-assisted system (CAS) for preoperative planning and intraoperative guidance during laparoscopic-assisted upper pancreatic lymph node dissection in distal gastrectomy for gastric cancer.
Methods: This study included 28 patients who underwent preoperative 3D reconstruction of the upper border of the pancreas using Hisense CAS (3D reconstruction group) for preoperative planning and intraoperative navigation. To determine its efficacy, the clinical data of these patients were compared with those of 28 patients who did not undergo 3D reconstruction (control group).
Results: Fifty-six cases of laparoscopic-assisted distal gastrectomy were performed. Three-dimensional reconstruction was successful in all the patients in the 3D reconstruction group, and real-time navigation was performed during the operation. The rate of correspondence between the 3D reconstruction images and intraoperative findings was 100%. The time taken for upper pancreatic lymph node dissection, number of upper pancreatic lymph node dissections, and number of unnecessary injuries during surgery were superior in the 3D reconstruction group than in the control group. The results of the remaining parameters were not statistically significant.
Conclusion: Preoperative planning with interactive Hisense CAS 3D reconstruction technology can improve surgeons' understanding of each patient's individual anatomy and can reveal anatomical variations, which is helpful for accurate preoperative planning and intraoperative navigation. This technique is helpful for the implementation of the precise dissection of lymph nodes at the upper edge of the pancreas and improves the quality and safety of the surgery.

Reducing Postoperative Opioid Use: A Comparison of Open Versus Ultrasound-Guided Regional Anesthesia for Patients Undergoing Open Pancreatoduodenectomy.
J Surg Oncol

Department of Surgery, Emory University School of Medicine, Atlanta, Georgia, USA.
Background: Opioid crisis is a national issue with significant economic burden and marked increase in opioid-related deaths, particularly following surgical procedures. Reducing opioid requirements while maintaining effective analgesia is critically challenging, perioperatively. Multimodal drug regimens and guided regional anesthesia (RA) have been adopted to address this issue.

Encountering Arc of Bühler during pancreaticoduodenectomy surgery.
BMJ Case Rep

The Arc of Bühler (AoB) is a rare anatomical variant in gastrointestinal vasculature where there is an aberrant anastomotic vessel between coeliac and superior mesenteric arteries. We present a rare case where AoB was noted intraoperatively to have haemodynamically significant flow in the context of coeliac artery stenosis, supplementing arterial supply to the hepatic artery proper via the gastroduodenal artery (GDA). An interpositional jump graft between the aorta and the GDA stump was created using the long saphenous vein, and flow was restored.

Department of General, Abdominal, Vascular and Transplant Surgery, Otto-von-Guericke University with University Hospital, Leipziger Str. 44, 39120 Magdeburg, Germany.
: Drawing upon over twenty years of clinical experience in endoscopic and endosonographic procedures, along with comprehensive literature research, we present an overview on EUS-guided pancreatography and pancreatic duct drainage (EUS-PD) as an alternative approach, encompassing indications, procedural methods, and outcomes, including complications and the success rate. Narrative review. (corner points): EUS-PD is indicated for cases, for which conventional methods are ineffective due to altered abdominal anatomy of the upper gastrointestinal (GI) tract, such as congenital or postoperative conditions that prevent access to the papilla or pancreatoenteric anastomosis.

Pancreaticobiliary maljunction (PBMJ) has a long common channel (CC) that causes pancreaticobiliary reflux (PBR), which has been implicated in gallstones, cholangiocarcinoma, and pancreatitis. By contrast, PBR has occurred in cases with normal and longer CCs than normal but shorter than PBMJ. This pathophysiology has been primarily reported in adults and rarely in children.
