Conversion during Minimally Invasive Left Pancreatectomy: A Nationwide Study of Causes and Consequences.

Objectives: To identify risk factors for conversion, develop a predictive Conversion Risk Score (CRS), and assess the association between conversion and severe postoperative complications.

Background: Conversion occurs in 15-30% of minimally invasive left pancreatectomies (MILP). Risk factors and potential negative impacts on postoperative outcomes are poorly described.

Robotic surgery for inguinal and ventral hernia repair: a systematic review and meta-analysis.

Background: This systematic review and meta-analysis assessed the effectiveness of robotic surgery compared to laparoscopy or open surgery for inguinal (IHR) and ventral (VHR) hernia repair.

Methods: PubMed and EMBASE were searched up to July 2022. Meta-analyses were performed for postoperative complications, surgical site infections (SSI), seroma/hematoma, hernia recurrence, operating time (OT), intraoperative blood loss, intraoperative bowel injury, conversion to open surgery, length of stay (LOS), mortality, reoperation rate, readmission rate, use of opioids, time to return to work and time to return to normal activities.

Use and outcome of minimally invasive pancreatic surgery in the European E-MIPS registry.

Background: The European registry for minimally invasive pancreatic surgery (E-MIPS) collects data on laparoscopic and robotic MIPS in low- and high-volume centers across Europe.

Methods: Analysis of the first year (2019) of the E-MIPS registry, including minimally invasive distal pancreatectomy (MIDP) and minimally invasive pancreatoduodenectomy (MIPD). Primary outcome was 90-day mortality.

Robotic Right Posterior Sectionectomy by Intrafascial Approach for Pancreas Neuroendocrine Liver Metastasis.

Background: Liver resection is indicated for resectable liver metastases of neuroendocrine tumors. Minimally invasive liver resection offers decreased blood loss, reduces pain, reduces postoperative complications, and reduces time to functional recovery. However, access to posterior section remains difficult with conventional laparoscopic tools.

In Vivo Modeling of CLL Transformation to Richter Syndrome Reveals Convergent Evolutionary Paths and Therapeutic Vulnerabilities.

Unlabelled: Transformation to aggressive disease histologies generates formidable clinical challenges across cancers, but biological insights remain few. We modeled the genetic heterogeneity of chronic lymphocytic leukemia (CLL) through multiplexed in vivo CRISPR-Cas9 B-cell editing of recurrent CLL loss-of-function drivers in mice and recapitulated the process of transformation from indolent CLL into large cell lymphoma [i.e.

Ambulatory colectomy for cancer: Results from a prospective bicentric study of 177 patients.

Background: The implementation of an Enhanced Recovery After Surgery programme after colectomy reduces postoperative morbidity and shortens the length of hospital stay.

Objective: To evaluate the short and midterm outcomes of ambulatory colectomy for cancer.

Methods: This was a two-centre, observational study of a database maintained prospectively between 2013 and 2021.

Robotic Left Hepatectomy Extended to Caudate Lobe and Common Biliary Duct for Hilar Cholangiocarcinoma.

Background: The safety and efficiency of minimally invasive approaches for liver resection have been confirmed (Wakabayashi in Ann Surg, 2015). However, laparoscopy suffers from several limitations due to technical difficulties, particularly for difficult hepatectomy with lymphadenectomy, biliary, and vascular reconstruction. Robotic assets could improve accessibility for difficult liver resections (Liu in World J Gastroenterol 25: 1432-1444), (Chou in Zhonghua Wai Ke Za Zhi 58: 230-234, 2020).

Activation of and Signaling via B-cell-Restricted Depletion of Generates a Consistent Murine Model of Chronic Lymphocytic Leukemia.

Chronic lymphocytic leukemia (CLL) is characterized by disordered DNA methylation, suggesting these epigenetic changes might play a critical role in disease onset and progression. The methyltransferase is a key regulator of DNA methylation. Although somatic mutations in CLL are rare, we found that low expression is associated with more aggressive disease.

Robotic central hepatectomy for hepatocarcinoma by glissonean approach (with video).

Background: Central bisegmentectomy of the liver implies excising Couinaud's segments IV, V and VIII (Couinaud and Le Foie, 1957) [1]. In a recent classification of laparoscopic liver resections, it belongs to the highly advanced level procedure group (Kawaguchi and et al., 2018 Jan) [2].

Robotic hepatic parenchymal transection: a two-surgeon technique using ultrasonic dissection and irrigated bipolar coagulation.

Liver transection is the most challenging part of hepatectomy due to the risk of hemorrhage which is associated with postoperative morbidity and mortality and reduced long-term survival. Parenchymal ultrasonic dissection (UD) with bipolar coagulation (BPC) has been widely recognized as a safe, effective, and standard technique during open and laparoscopic hepatectomy. We here introduce our technique of robotic liver transection using UD with BPC and report on short-term perioperative outcomes.

Robotic Resection of a Central Liver Solitary Fibrous Tumor (with Video).

Background: Solitary fibrous tumor is a mesenchymal tumor rare in liver parenchyma 1 but must be considered as a differential diagnosis of a single large hepatic mass. Surgical resection is the treatment because of its potential malignancy, and previous interventions reported were open hepatectomy 2. Robotic assets could improve accessibility for difficult liver resection 3.

The technique and outcomes of central hepatectomy by the Glissonian suprahilar approach.

Introduction: Central hepatectomy (CH) is technically challenging and seldom-used to treat centrally located tumors. However, CH is a parenchyma-sparing resection that may decrease the risk of postoperative liver failure. This retrospective study presents our technique of CH and assesses the outcomes.

A Murine Model of Chronic Lymphocytic Leukemia Based on B Cell-Restricted Expression of Sf3b1 Mutation and Atm Deletion.

SF3B1 is recurrently mutated in chronic lymphocytic leukemia (CLL), but its role in the pathogenesis of CLL remains elusive. Here, we show that conditional expression of Sf3b1-K700E mutation in mouse B cells disrupts pre-mRNA splicing, alters cell development, and induces a state of cellular senescence. Combination with Atm deletion leads to the overcoming of cellular senescence and the development of CLL-like disease in elderly mice.

Splicing modulation sensitizes chronic lymphocytic leukemia cells to venetoclax by remodeling mitochondrial apoptotic dependencies.

The identification of targetable vulnerabilities in the context of therapeutic resistance is a key challenge in cancer treatment. We detected pervasive aberrant splicing as a characteristic feature of chronic lymphocytic leukemia (CLL), irrespective of splicing factor mutation status, which was associated with sensitivity to the spliceosome modulator, E7107. Splicing modulation affected CLL survival pathways, including members of the B cell lymphoma-2 (BCL2) family of proteins, remodeling antiapoptotic dependencies of human and murine CLL cells.

Do height and weight affect the feasibility of single-incision laparoscopic cholecystectomy?

Background: Laparoscopic cholecystectomy is the gold standard for gallbladder removal and the most common laparoscopic procedure worldwide. Single-incision laparoscopic surgery has recently emerged as a less invasive potential alternative to conventional three- or four-port laparoscopy. However, the feasibility of single-incision laparoscopic cholecystectomy (SILC) remains unclear, and there are no rigorous criteria in the literature.

Which treatment to choose for portal biliopathy with extensive portal thrombosis?

Background: Portal biliopathy refers to abnormalities of the biliary tract developing in relation to portal hypertension. Portosystemic splenorenal or mesenterico-caval shunting is a safe and effective method to relieve biliary obstruction in symptomatic patients but is unfeasible in cases of extensive thrombosis of the splenic and superior mesenteric veins. In such cases, a makeshift portosystemic shunt between a suitable portal varix and the caval system can be an interesting alternative.
