Article Synopsis
  • International guidelines for imaging follow-up after pancreatic resection for pancreatic ductal adenocarcinoma (PDAC) are inconsistent, leading to varied follow-up strategies globally.
  • The study aimed to compare clinical outcomes, including treatment for recurrence and survival rates, between patients who received either symptomatic follow-up or routine imaging after PDAC surgery across 33 international centers.
  • A total of 333 patients were analyzed, showing that 29% had symptomatic follow-up while 71% underwent routine imaging, with overall survival rates being examined through statistical methods to identify the impact of the follow-up strategy on patient outcomes.

The key to the successful management of pancreatic cystic neoplasm (PCN), among which intraductal papillary mucinous neoplasm (IPMN) is the one with the highest risk of advanced neoplasia in resected patients, is a careful combination of clinical, radiological, and histopathological findings. This study aims to perform the comparison of a preoperative evaluation with pathological reports in IPMN and further, to evaluate and compare the diagnostic performance of European evidence-based guidelines on pancreatic cystic neoplasms (EEBGPCN) and Fukuoka Consensus guidelines (FCG). We analyzed 106 consecutive patients diagnosed with different types of PCN, among whom 68 had IPMN diagnosis, at the Clinical Center of Serbia.

Objective: To assess outcomes among patients undergoing total pancreatectomy (TP) including predictors for complications and in-hospital mortality.

Background: Current studies on TP mostly originate from high-volume centers and span long time periods and therefore may not reflect daily practice.

Methods: This prospective pan-European snapshot study included patients who underwent elective (primary or completion) TP in 43 centers in 16 European countries (June 2018-June 2019).

Pancreatic cancer (PC) is very aggressive and it is estimated that it kills nearly 50% of patients within the first six months. The lack of symptoms specific to this disease prevents early diagnosis and treatment. Today, gemcitabine alone or in combination with other cytostatic agents such as cisplatin (Cis), 5-fluorouracil (5-FU), irinotecan, capecitabine, or oxaliplatin (Oxa) is used in conventional therapy.

One of the main reasons for the dismal prognosis of pancreatic ductal adenocarcinoma (PDAC) is its late diagnosis. At the time of presentation, only approximately 15-20% of all patients with PDAC are considered resectable and around 30% are considered borderline resectable. A surgical approach, which is the only curative option, is limited in borderline resectable patients by local involvement of surrounding structures.

Background: Clinically relevant postoperative pancreatic fistula (grades B and C of the ISGPS definition) remains the most troublesome complication after pancreatoduodenectomy. The approach to management of the pancreatic remnant via some form of pancreatico-enteric anastomosis determines the incidence and severity of clinically relevant postoperative pancreatic fistula. Despite numerous trials comparing diverse pancreatico-enteric anastomosis techniques and other adjunctive strategies (pancreatic duct stenting, somatostatin analogues, etc), currently, there is no clear consensus regarding the ideal method of pancreatico-enteric anastomosis.

Abdominal compartment syndrome (ACS) in patients with severe acute pancreatitis (SAP) is a marker of severe disease. It occurs as combination of inflammation of retroperitoneum, visceral edema, ascites, acute peripancreatic fluid collections, paralytic ileus, and aggressive fluid resuscitation. The frequency of ACS in SAP may be rising due to more aggressive fluid resuscitation, a trend towards conservative treatment, and attempts to use a minimally invasive approach.
