Objective: To compare nationwide outcomes of robotic liver resection (RLR) with laparoscopic liver resection (LLR).
Background: Minimally invasive liver resection is increasingly performed using the robotic approach as this could help overcome inherent technical limitations of laparoscopy. It is unknown if this translates to improved patient outcomes.
Introduction And Purpose: It is unknown what the incidence of gastroscopy-diagnosed marginal ulceration is, while gastroscopy is a frequently chosen diagnostic modality in patients presenting with abdominal pain with a Roux-en-Y gastric bypass (RYGB) in history. The aim of this study was to examine the incidence and treatment of gastroscopy-diagnosed marginal ulceration in patients presenting with the first episode of abdominal pain after RYGB, in which gastroscopy is chosen as the first step in the diagnostic work-up.
Material And Methods: A post hoc analysis was performed of a prospective cohort of 2273 patients undergoing RYGB between 2014 and 2019 in a large non-academic hospital with a dedicated bariatric unit.
Article Synopsis
- * Out of 3,530 patients, 11.6% required conversion, with robotic procedures having a lower conversion rate compared to laparoscopic ones, and conversion associated with various complications, like increased blood loss and longer hospital stays.
- * Emergency conversions showed even more severe outcomes, such as significantly higher blood loss and increased rates of intensive care admissions compared to non-emergency cases.
Background: Postoperative cholangitis is a common complication after pancreatoduodenectomy that can occur with or without anatomical biliary obstruction. This study aimed to investigate the incidence, diagnosis, treatment, and risk factors of cholangitis after pancreatoduodenectomy.
Methods: We performed a retrospective cohort study of consecutive patients who underwent pancreatoduodenectomy in 2 Dutch tertiary pancreatic centers (2010-2019).
Importance: Unintended tumor-positive resection margins occur frequently during minimally invasive surgery for colorectal liver metastases and potentially negatively influence oncologic outcomes.
Objective: To assess whether indocyanine green (ICG)-fluorescence-guided surgery is associated with achieving a higher radical resection rate in minimally invasive colorectal liver metastasis surgery and to assess the accuracy of ICG fluorescence for predicting the resection margin status.
Design, Setting, And Participants: The MIMIC (Minimally Invasive, Indocyanine-Guided Metastasectomy in Patients With Colorectal Liver Metastases) trial was designed as a prospective single-arm multicenter cohort study in 8 Dutch liver surgery centers.
