Graduated Autonomy of Laparoscopic Liver Resection Based on Liver Resection Complexity: A Western and Eastern Bi-Institution Study for Learning Curve.

Introduction: Laparoscopic liver resection (LLR) requires a high degree of expertise in both hepatobiliary and minimally invasive surgery. Our group previously reported a 3-level LLR complexity classification based on intra-postoperative outcomes: grade I (low), grade II (intermediate), and grade III (high). We evaluated the learning curve effect in each complexity grade to assess the experience needed for a surgeon to safely progress through the grades.

Debulking hepatectomy for colorectal liver metastasis: Analysis of risk factors for progression free survival.

Background: The study explores the role of liver debulking surgery in cases of unresectable colorectal liver metastases (CRLM), challenging the traditional notion that surgery is not a valid option in such scenarios.

Materials And Methods: Patients with advanced but resectable disease who underwent surgery with a curative intent (Group I) and those with advanced incompletely resectable disease who underwent a "debulking" hepatectomy (Group II) were compared.

Results: There was no difference in the intra-operative and post-operative results between the two groups.

Short-term outcomes of laparoscopic extended hepatectomy versus major hepatectomy: a single-center experience.

Introduction: Laparoscopic major hepatectomy (LMH) remains restricted to a few specialized centers and poses a challenge to surgeons performing laparoscopic resections. Laparoscopic extended resections are even more complex and rarely conducted.

Methods: From a single-institution database, we compared the short-term outcomes of patients who underwent major and extended laparoscopic resections, stratifying the entire retrospective cohort into four groups: right hepatectomy, left hepatectomy, right extended hepatectomy, and left extended hepatectomy.

Factors of oncological failure in two stage hepatectomy for colorectal liver metastases.

Background: Two-stage hepatectomy (TSH) has increased the chance of surgical resections for bilobar colorectal liver metastases (CRLM). Nevertheless, drop-out between stages and early recurrence rates raise the question of surgical futility in some situations. This study aimed to identify factors of TSH oncological failure.

Oncological Outcome After Laparoscopic 'No-touch' RAMPS 'Touch' Left Pancreatectomy for Pancreatic Adenocarcinoma.

Background/aim: The validity of laparoscopic distal pancreatectomy in left-sided pancreatic adenocarcinoma (PDAC) is still unclear. However, a meticulous surgical dissection through a "no-touch" technique might allow a radical oncological resection with minimal risk of tumor dissemination and seeding. This study aimed to evaluate the oncological outcomes of the laparoscopic "no touch" technique versus the "touch" technique.
