An Inanimate Intracorporeal Anastomosis Model With Real-Time Force Feedback: An Initial Study.

Introduction: Laparoscopic intestinal anastomosis requires specific technical skills and should be trained in a safe simulation environment before performing surgery in daily practice. However, anastomosis simulation training with objective feedback is not widely available. This study aimed to analyze a laparoscopic intestinal anastomosis training task that utilizes objective force, motion, and time measurements.

Outcome of a 'step-up approach' for recurrent cholangitis in patients with a non-stenotic hepaticojejunostomy after hepato-pancreato-biliary surgery: single center series.

Background: Recurrent non-stenotic cholangitis (NSC) is a challenging and poorly understood complication of a surgical hepaticojejunostomy (HJ). Optimal treatment remains unclear.

Methods: A retrospective single center series including patients with recurrent cholangitis with a non-stenotic HJ after hepato-pancreato-biliary surgery was conducted (2015-2022).

Optimizing EUS-guided choledochoduodenostomy with lumen-apposing metal stents for primary drainage of malignant distal biliary obstruction (SCORPION-IIp): a prospective pilot study.

Background And Aims: Biliary drainage by ERCP in patients with malignant distal bile duct obstruction (MBO) is frequently associated with adverse events, such as pancreatitis, hampering patient outcomes. EUS-guided choledochoduodenostomy (EUS-CDS) with a lumen-apposing metal stent (LAMS) is a promising alternative in patients with MBO but is associated with a worrisome risk of stent dysfunction. Placement of a fully covered self-expandable metal stent (FCSEMS) through the LAMS, thereby changing the axis of biliary drainage toward the descending duodenum, may decrease the risk of stent dysfunction while maintaining high technical success and low adverse event rates.

Background: Breast cancer is the most common cancer in women, and breast reconstruction improves the patient's quality of life. Autologous breast reconstruction provides benefits of natural appearance, feel, and long-term results without implant-associated problems. However, thin patients are not always suitable for standard autologous reconstructions.

Artificial intelligence-aided ultrasound imaging in hepatopancreatobiliary surgery: where are we now?

Background: Artificial intelligence (AI) models have been applied in various medical imaging modalities and surgical disciplines, however the current status and progress of ultrasound-based AI models within hepatopancreatobiliary surgery have not been evaluated in literature. Therefore, this review aimed to provide an overview of ultrasound-based AI models used for hepatopancreatobiliary surgery, evaluating current advancements, validation, and predictive accuracies.

Method: Databases PubMed, EMBASE, Cochrane, and Web of Science were searched for studies using AI models on ultrasound for patients undergoing hepatopancreatobiliary surgery.

Risk Factor Targeted Perioperative Care Reduces Anastomotic Leakage after Colorectal Surgery: The DoubleCheck study.

Objective: The DoubleCheck study aimed to introduce pre- and perioperative interventions minimizing exposure to modifiable risk factors and determine its effect on CAL.

Summary Background Data: Colorectal anastomotic leakage (CAL) is a severe complication. In order to predict and prevent its occurrence, the LekCheck study identified intraoperative modifiable risk factors for CAL: anemia, hyperglycemia, hypothermia, incorrect timing of antibiotic prophylaxis, administration of vasopressors and epidural analgesia.

Robotic hepaticojejunostomy training in novices using robotic simulation and dry-lab suturing (ROSIM): randomized controlled crossover trial.

Background: Robotic suturing training is in increasing demand and can be done using suture-pads or robotic simulation training. Robotic simulation is less cumbersome, whereas a robotic suture-pad approach could be more effective but is more costly. A training curriculum with crossover between both approaches may be a practical solution.

Surgery for Locally Advanced Pancreatic Cancer Following Induction Chemotherapy: A Single-Center Experience.

Background: The use of surgery in patients with locally advanced pancreatic cancer (LAPC) following induction chemotherapy is increasing. However, most series do not report on the total cohort of patients undergoing surgical exploration; therefore, this single-center study investigates outcomes among all consecutive patients with LAPC who underwent surgical exploration.

Methods: We conducted a retrospective, single-center analysis including all consecutive patients with LAPC (Dutch Pancreatic Cancer Group criteria) who underwent surgical exploration with curative intent (January 2014-June 2023) after induction therapy.

Training in robotic-assisted surgery: a systematic review of training modalities and objective and subjective assessment methods.

Introduction: The variety of robotic surgery systems, training modalities, and assessment tools within robotic surgery training is extensive. This systematic review aimed to comprehensively overview different training modalities and assessment methods for teaching and assessing surgical skills in robotic surgery, with a specific focus on comparing objective and subjective assessment methods.

Methods: A systematic review was conducted following the PRISMA guidelines.

[Gastric rupture as a complication of anorexia nervosa].

Background: Anorexia nervosa may cause several gastro-intestinal complications.

Case Description: A 21-year-old woman presented herself with abdominal pain and vomiting a day after her first binge-eating episode. In her recent history she had lost 40 kg in weight and her BMI was 15 at presentation.

Surgical quality assessment of critical view of safety in 283 laparoscopic cholecystectomy videos by surgical residents and surgeons.

Introduction: Surgical quality assessment has improved the efficacy and efficiency of surgical training and has the potential to optimize the surgical learning curve. In laparoscopic cholecystectomy (LC), the critical view of safety (CVS) can be assessed with a 6-point competency assessment tool (CAT), a task commonly performed by experienced surgeons. The aim of this study is to determine the capability of surgical residents to perform this assessment.

Artificial intelligence-powered clinical decision making within gastrointestinal surgery: A systematic review.

Background: Clinical decision-making in gastrointestinal surgery is complex due to the unpredictability of tumoral behavior and postoperative complications. Artificial intelligence (AI) could aid in clinical decision-making by predicting these surgical outcomes. The current status of AI-based clinical decision-making within gastrointestinal surgery is unknown in recent literature.

Impact of FDG-PET/CT and Laparoscopy in Staging of Locally Advanced Gastric Cancer: A Cost Analysis in the Prospective Multicenter PLASTIC-Study.

Background: Unnecessary D2-gastrectomy and associated costs can be prevented after detecting non-curable gastric cancer, but impact of staging on treatment costs is unclear. This study determined the cost impact of F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) and staging laparoscopy (SL) in gastric cancer staging.

Materials And Methods: In this cost analysis, four staging strategies were modeled in a decision tree: (1) FDG-PET/CT first, then SL, (2) SL only, (3) FDG-PET/CT only, and (4) neither SL nor FDG-PET/CT.

Background: Prophylactic passive abdominal drainage is standard practice after distal pancreatectomy. This approach aims to mitigate the consequences of postoperative pancreatic fistula (POPF) but its added value, especially in patients at low risk of POPF, is currently being debated. We aimed to assess the non-inferiority of a no-drain policy in patients after distal pancreatectomy.
