Objective: The aim of this study was to compare oncological outcomes after minimally invasive distal pancreatectomy (MIDP) with open (ODP) in patients pancreatic ductal adenocarcinoma (PDAC). Background: Cohort studies have suggested superior short-term MIDP vs. ODP. Recent international surveys, however, revealed that surgeons concerns about the for PDAC. Methods: This is a pan-European propensity score matched including who underwent (laparoscopic or robot-assisted) ODP PDAC between...
Objective: To develop and update evidence- consensus-based guidelines on laparoscopic robotic pancreatic surgery. Summary Background Data: Minimally invasive surgery (MIPS), including surgery, is complex technically demanding. Minimizing the risk for patients requires stringent, evidence-based guidelines. Since International Miami Guidelines MIPS in 2019, new developments key publications have been reported, necessitating an update. Methods: Evidence-based 22 topics 8 domains were proposed:...
Abstract Background Pancreatoduodenectomy with superior mesenteric–portal vein resection has become a common procedure in pancreatic surgery. The aim of this study was to compare standard pancreatoduodenectomy plus venous at high-volume centre, and examine trends management outcome over decade for the latter procedure. Methods This retrospective observational included all patients undergoing or without Oslo University Hospital between January 2006 December 2015. Trends were evaluated by...
Abstract Background Benchmarking is the process to used assess best achievable results and compare outcomes with that standard. This study aimed in minimally invasive distal pancreatectomy splenectomy (MIDPS). Methods retrospective included consecutive patients undergoing MIDPS for any indication, between 2003 2019, 31 European centres. Benchmarks of main clinical were calculated according Achievable Benchmark Care (ABC™) method. After identifying independent risk factors severe morbidity...
Abstract Background Every fifth patient undergoing left pancreatectomy develops a postoperative pancreatic fistula (POPF). Accurate POPF risk prediction could help. Two independent preoperative models have been developed and externally validated: DISPAIR D-FRS. The aim of this study was to validate, compare, possibly update the models. Methods Patients from nine high-volume surgery centres (8 in Europe 1 North America) were included retrospective cohort study. Inclusion criteria age over 18...
As a small country with population of 3 million, Armenia has been severely affected by the COVID-19 pandemic, and for several months was among countries highest prevalence COVID-19.1Our World In DataCoronavirus pandemic data explorer.https://ourworldindata.org/coronavirus-data-explorerDate accessed: October 23, 2020Google Scholar On Oct 2020, number confirmed cases 70 836 new daily diagnosed reached 2484. result, is now second in world per person (778 million day), overtaking only Czech...
Abstract Background Benchmarking is an important tool for quality comparison and improvement. However, no benchmark values are available minimally invasive spleen-preserving distal pancreatectomy, either laparoscopically or robotically assisted. The aim of this study was to establish benchmarks these techniques using two different methods. Methods Data from patients undergoing assisted pancreatectomy were extracted a multicentre database (2006–2019). Benchmarks 10 outcomes calculated the...
Understanding the learning curve of a new complex surgical technique helps to reduce potential patient harm. Current series on minimally invasive distal pancreatectomy (MIDP) are mostly small, single-center series, thus providing limited data.
Abstract Background Laparoscopic liver resection (LLR) of colorectal metastases (CLM) is increasingly performed in specialized centers. While there a trend towards parenchyma-sparing strategy multimodal treatment for CLM, its role yet unclear. In this study we present short- and long-term outcomes laparoscopic (LPSLR) at single center. Patients methods LLR were 951 procedures between August 1998 March 2017 Oslo University Hospital, Oslo, Norway. who primarily underwent LPSLR CLM included the...
ObjectiveSuperior mesenteric vein/portal vein (SMV/PV) resection and reconstruction during pancreatic surgery are increasingly common. Several techniques exist. The aim of this study was to evaluate characteristics patients clinical outcomes for SMV/PV using interposed cold-stored cadaveric venous allograft (AG+) or primary end-to-end anastomosis (AG−) after segmental resections surgery.MethodsAll undergoing with from 2006 2015 were identified. Clinical histopathologic as well preoperative...
Background The outcomes following laparoscopic distal pancreatectomy (LDP) in elderly patients have not been widely reported to date. This study aimed analyze perioperative and oncologic aged ≥70 years (elderly group) compare with those <70 (non-elderly group). Methods From April 1997 September 2015, 402 consecutive lesions the body tail of pancreas underwent LDP at Rikshospitalet, Oslo University Hospital. Results Of these, 118 (29.4%) were elderly, whereas 284 (70.6%) non-elderly. Despite...
Abstract Background Surgical factors, including resection of Gerota’s fascia, R0-resection, and lymph node yield, may be associated with survival after distal pancreatectomy (DP) for pancreatic ductal adenocarcinoma (PDAC), but evidence from large multicenter studies is lacking. This study aimed to identify predictors overall DP PDAC, especially those related surgical technique. Patients Methods Data an international retrospective cohort patients 11 European countries the USA who underwent...
Objective: To compare short-term clinical outcomes after Kimura and Warshaw MIDP. Background: Spleen preservation during distal pancreatectomy can be achieved by either (Kimura) or resection (Warshaw) of the splenic vessels. Multicenter studies reporting spleen-preserving MIDP are scarce. Methods: retrospective study including consecutive procedures intended to from 29 high-volume centers (≥15 pancreatectomies annually) in 8 European countries. Primary were secondary splenectomy for ischemia...
Resection margin status is considered one of the few surgeon-controlled parameters affecting prognosis in pancreatic ductal adenocarcinoma (PDAC). While studies mostly focus on resection margins pancreatoduodenectomy, little known about their role distal pancreatectomy (DP). This study aimed to investigate DP for PDAC.Patients who underwent PDAC between October 2004 and February 2020 were included (n = 124). associated studied two consecutive time periods during which different pathology...
Objective The aim of this study was to validate clinical risk scores in patients underwent laparoscopic resection colorectal liver metastases (CLM) with 5 years follow‐up or more, and assess 5‐ 10‐year actual survival group. Methods A total 516 resections were performed 406 CLM between February 1998 September 2015. 10 could be assessed 144 29 patients, respectively. Fong score, pre‐ postoperative Basingstoke Predictive Index (BPI), Nordlinger Iwatsuki score validated. Results Five‐ ten‐year...
