Objective: To validate the ISGPS complexity grading system for minimally invasive pancreaticoduodenectomy (MIPD).
Background: Although concerns about patient safety persist, MIPD is gaining popularity. The ISGPS recently introduced a difficulty grading system to improve patient selection by aligning procedural complexity with surgeon and center expertise.
Background: Severe aortic stenosis (AS) coexists with coronary artery disease (CAD) in approximately 50% of patients. The preferred treatment is combined surgical aortic valve replacement (SAVR) and coronary artery bypass grafting (CABG). However, transcatheter aortic valve replacement (TAVR) along with percutaneous coronary intervention (PCI) has emerged as a viable alternative.

Its etiology is multifactorial and depends on the characteristics and co-morbidities of the patient, the tumor type and extension, and the oncological treatment. The management of VTE is more complex in patients with cancer due to an increased risk of recurrence and major bleeding complications during anticoagulation compared to the general non-oncological population.

- Zenker's diverticulum peroral endoscopic myotomy (Z-POEM) with mucosal flap incision (MFI) shows high effectiveness for treating symptomatic Zenker's diverticulum, as reported in a study involving 36 patients across eight international centers.
- Clinical success was achieved in 97% of patients, with significant improvement in symptoms measured by the Kothari-Haber symptom score (KHSS).
- The procedure demonstrated a strong technical success rate, with only one minor adverse event, indicating it is a safe option for patients with this condition, although further prospective evaluations are necessary for larger diverticulums.
Venous thromboembolism (VTE) after hospital discharge poses a serious health risk. Assessments of patient characteristics, prophylaxis, treatment, outcomes, and over time changes lack consistency. Data on 16,901 hospitalized patients in the Registro Informatizado Enfermedad TromboEmbolica registry (2003-2022) were analyzed to evaluate trends in baseline characteristics, prophylaxis, treatments, and 90-day outcomes among medical (6,218) and surgical (10,683) patient cohorts.

- A study was conducted to compare robotic minor liver resections (RMLR) with laparoscopic minor liver resections (LMLR) in patients undergoing surgery on the anterolateral liver segments.
- The analysis included over 10,000 patients and employed propensity score matching to balance the groups for accuracy in comparisons.
- Results indicated RMLR had benefits like less blood loss, lower major morbidity, and shorter hospital stays than LMLR, although the difference in 30-day readmission rates suggested RMLR may have some drawbacks.
Objective: To compare minimally invasive and open pancreatoduodenectomy in different subtypes of ampullary adenocarcinoma.
Summary Background Data: Ampullary adenocarcinoma (AAC) is widely seen as the best indication for minimally invasive pancreatoduodenectomy (MIPD) due to the lack of vascular involvement and dilated bile and pancreatic duct. However, it is unknown whether outcomes of MIPD for AAC differ between the pancreatobiliary (AAC-PB) and intestinal (AAC-IT) subtypes as large studies are lacking.
Introduction And Objectives: Impact of gender on long-term outcomes after transcatheter aortic valve implantation (TAVI) remains uncertain. We aimed to investigate gender-specific differences in TAVI and its impact on outcomes.
Methods: This analysis used data from the prospective Spanish TAVI registry, which included consecutive TAVI patients treated in 46 Spanish centers from 2009 to 2021.
Background And Aims: Patients with sigmoid-type achalasia can be challenging to treat with peroral endoscopic myotomy (POEM). A short myotomy improves technical success; however, outcomes have not previously been evaluated.
Methods: This was a multicenter, international, retrospective study of patients who underwent POEM with short (≤4 cm) or standard esophageal myotomy.
Article Synopsis
- The study is looking to see if a new program called VIDACTIVA can help older adults in Lima, Peru, who are feeling depressed, compared to regular care they usually get.
- They will have 64 older participants split into two groups: one will get the VIDACTIVA sessions, and the other will get some basic help and be told to go to healthcare centers.
- If this small study shows good results, they plan to do a bigger trial to see how well the VIDACTIVA program works overall.
High pathogenicity avian influenza viruses (HPAIVs) have caused major epizootics in recent years, with devastating consequences for poultry and wildlife worldwide. Domestic and wild ducks can be highly susceptible to HPAIVs, and infection leads to efficient viral replication and massive shedding (i.e.

- - This national survey aimed to assess the use of liver hypertrophy techniques in Italy, focusing on trends and differences among various medical centers.
- - In December 2022, 46 centers completed a detailed online questionnaire, revealing that hypertrophy techniques were used in 6.2% of liver resections, with PVE and ALPPS being the most common techniques employed.
- - The findings indicated that while these techniques play a crucial role in increasing resectability, there is substantial inconsistency in how centers define the need for them and the protocols used for patient allocation.
Introduction: Unlike high-income countries (HICs), there are few early intervention services for psychosis in low-and middle-income countries (LAMICs). In HICs, research spurred the growth of such services. Little is known about the state of EIP research in LAMICs, which we address by examining their research output and collaborations vis-à-vis that of HICs.

- It analyzed data from 854 patients across 57 centers globally, establishing key performance benchmarks for low-risk cases based on specific outcome indicators.
- The findings set standard benchmarks for metrics like operation time and complication rates, serving as a reference for surgical auditing and improvement.
Background: Cancer arising in the periampullary region can be anatomically classified in pancreatic ductal adenocarcinoma (PDAC), distal cholangiocarcinoma (dCCA), duodenal adenocarcinoma (DAC), and ampullary carcinoma. Based on histopathology, ampullary carcinoma is currently subdivided in intestinal (AmpIT), pancreatobiliary (AmpPB), and mixed subtypes. Despite close anatomical resemblance, it is unclear how ampullary subtypes relate to the remaining periampullary cancers in tumor characteristics and behavior.
View Article and Find Full Text PDFBackground: Despite differences in tumour behaviour and characteristics between duodenal adenocarcinoma (DAC), the intestinal (AmpIT) and pancreatobiliary (AmpPB) subtype of ampullary adenocarcinoma and distal cholangiocarcinoma (dCCA), the effect of adjuvant chemotherapy (ACT) on these cancers, as well as the optimal ACT regimen, has not been comprehensively assessed. This study aims to assess the influence of tailored ACT on DAC, dCCA, AmpIT, and AmpPB.
Patients And Methods: Patients after pancreatoduodenectomy for non-pancreatic periampullary adenocarcinoma were identified and collected from 36 tertiary centres between 2010 - 2021.

- The 2022 Barcelona Clinic Liver Cancer algorithm advises against liver resection for patients with multiple small tumors (2 or 3 nodules, each ≤3 cm) in hepatocellular carcinoma.
- This study retrospectively analyzed data from over 12,000 patients to compare survival outcomes among those undergoing liver resection (LR), percutaneous radiofrequency ablation (PRFA), and transarterial chemoembolization (TACE).
- Results showed that LR had the highest survival rates at 1, 3, and 5 years (89.11%, 70.98%, 56.44% respectively) compared to PRFA and TACE, indicating that LR may offer better long-term outcomes in treating early multin
Introduction And Objectives: The optimal chronic antithrombotic regimen for patients with atrial fibrillation undergoing transcatheter aortic valve implantation (TAVI) remains uncertain. Our aim was to compare the incidence of late bleeding events between patients on direct oral anticoagulants (DOACs) and those on vitamin-K antagonists (VKA).
Methods: This single-center observational study included TAVI patients requiring oral anticoagulation at discharge between 2015 and 2021.
Article Synopsis
- Minimally invasive liver surgery has become more common over the last 30 years, especially for treating colorectal liver metastases, but the effects of neoadjuvant chemotherapy on surgical outcomes are not well understood.
- A study analyzed a large database of nearly 5,000 patients who underwent minimally invasive liver surgeries to compare outcomes between those who received neoadjuvant chemotherapy and those who did not.
- The results showed that neoadjuvant chemotherapy did not significantly affect the short-term surgical outcomes in patients undergoing these liver procedures.
Article Synopsis
- Digital single-operator cholangioscopy (DSOC) is a technique for diagnosing and treating biliary duct disorders, but traditional systems faced issues like cost and image quality.
- A new system called eyeMAX was developed to improve these limitations; the study assessed its diagnostic accuracy and safety across 80 patients from two cohorts—diagnostic and therapeutic.
- Results showed high sensitivity (91.6%) and specificity (87.5%) for diagnosing neoplasms, with successful stone removal for 71% of patients who required treatment, and no adverse events reported during the procedures.
Background And Aims: EUS-guided radiofrequency ablation (EUS-RFA) has emerged as an alternative for the local treatment of unresectable pancreatic ductal adenocarcinoma (PDAC). We assessed the feasibility and safety of EUS-RFA in patients with unresectable PDAC.
Methods: This study followed an historic cohort compounded by locally advanced (LA-) and metastatic (m)PDAC-naïve patients who underwent EUS-RFA between October 2019 and March 2022.
