Article Synopsis
  • This study assessed the effectiveness of robotic versus laparoscopic limited liver resections for tumors in challenging areas of the liver from 2010 to 2019 across 24 centers.
  • The analysis included 983 patients and found that robotic techniques led to less blood loss, fewer conversions to open surgery, and shorter operation times compared to laparoscopic techniques.
  • Overall, both approaches were deemed safe and effective for removing tumors in the posterosuperior liver segments.

Article Synopsis
  • A study was conducted to assess the relationship between pancreatic duct size and the risk of postoperative pancreatic fistula (POPF) in patients undergoing duct-to-mucosa pancreaticojejunostomy (DTMPJ) after pancreaticoduodenectomy.
  • Out of 288 patients studied from 2003 to 2019, 56.3% experienced POPF, with the highest incidence occurring in those with duct diameters ≤ 1 mm, showing a significant risk increase compared to larger ducts.
  • The findings suggest that DTMPJ is safe for patients with pancreatic ducts larger than 1 mm, indicating that smaller duct size is a predictor for higher POPF rates, especially in patients with a soft pancreas.

Article Synopsis
  • The study aimed to compare survival outcomes for solitary hepatocellular carcinoma (HCC) patients under 5 cm treated with transarterial ethanol ablation (TEA) versus liver resection (LR), using the ALBI grading system for liver function.
  • After analyzing 225 treatment-naïve patients over a follow-up period of at least 7 years, results showed significantly longer overall and recurrence-free survival in the LR group compared to the TEA group.
  • However, for patients with ALBI grades 2 or 3, survival rates were similar between TEA and LR, indicating that ALBI grade can help in deciding the appropriate treatment for these patients.

Background: Robotic distal pancreatectomy has been accepted to be safe and effective for pancreatic tail lesion. Whether spleen preservation by preserving the splenic vessels with robot assistance is feasible and beneficial remains controversial. Here we would like to compare the operative outcomes of robotic distal pancreatectomy and splenectomy (DPS) with robotic spleen preserving distal pancreatectomy by means of splenic vessel preservation (SVP).

Background: Although endoscopic ultrasound (EUS) features and criteria have been described in chronic pancreatitis, challenges remain with interoperator variability and ease of adoption. The aim of this study was to define and validate the EUS features of chronic pancreatitis in a multicenter prospective study in Asia.

Method: The study was divided into two parts: the first part was conducted to derive the EUS features of chronic pancreatitis with adequate interoperator agreement; the second was to prospectively evaluate these features in a multicenter cross-sectional study and determine the optimal combination of features for the diagnosis of chronic pancreatitis.

Purpose: The objective was to evaluate the local treatment efficacy of transarterial ethanol ablation (TEA) as compared to radiofrequency ablation (RFA) for small hepatocellular carcinoma (HCC).

Materials And Methods: This was a retrospective study between January 2005 and April 2017, in which the treatment outcomes of all patients who received either percutaneous TEA or RFA for HCC tumors of size ≤ 3 cm, of Child-Pugh grade A or B, received no prior treatment other than surgical resection, were compared. For TEA, a mixture of absolute ethanol and ethiodized oil at a proportion of 1:2 by volume was administered superselectively into the tumor via a microcatheter placed at the feeding arteries.

The absence of potent therapeutic option accounts for the dismal prognosis of advanced hepatocellular carcinoma (HCC) with high mortality and recurrence rate. For a decade, sorafenib is the only approved systemic drug in the first-line setting and warrants as the standard-of-care for HCC in the advanced stage. Given the common failures of chemotherapies and targeted therapies in the field of HCC treatment, promising breakthroughs were eagerly needed and until recently, immunotherapies have opened a new era of anticancer treatment.

Background: Transarterial chemoembolization (TACE) is the most commonly used adjuvant therapy for hepatocellular carcinoma (HCC) after curative resection. Responses to TACE are variable due to tumor and patient heterogeneity. We had previously demonstrated that expression of Granulin-epithelin precursor (GEP) and ATP-dependent binding cassette (ABC)B5 in liver cancer stem cells was associated with chemoresistance.
