Background: This study aimed to evaluate the clinical significance of acinar content at the pancreatic resection margin after partial pancreatoduodenectomy (PD).

Methods: A total of 228 consecutive patients undergoing PD were included for analysis. Resection margins were assessed for acinar, fibrosis, and fat contents by 2 pathologists blinded to the patients' clinical data.

Purpose: To compare the predictive value of serum amylase and lipase regarding the occurrence of clinically relevant postoperative pancreatic fistula (cr-POPF) after partial pancreaticoduodenectomy (PD).

Methods: Data from 228 consecutive patients undergoing PD were obtained from a prospective database. Serum amylase and lipase were measured on postoperative days (PODs) 0-2.

Introduction: The present study aimed to examine the clinical implications of postoperative hyperamylasemia (POH) after partial pancreaticoduodenectomy (PD).

Methods: Data from all consecutive patients undergoing PD were obtained from a prospectively maintained database and reviewed. POH was defined as an elevation of serum pancreatic amylase above the upper limit of normal (53 U/L) on postoperative days 0-2.

Introduction: The goal of primary tumor resection with lymphadenectomy (PTR) in small intestine neuroendocrine neoplasms (SI-NENs) is to avoid local recurrence while sparing as much of the small bowel as possible, even in the case of extensive mesenteric fibrosis. The results of PTR with retrograde vessel-sparing lymphadenectomy (VS-LA) were compared to those of conventional lymphadenectomy (Con-LA).

Methods: Prospectively collected clinical, surgical and pathological data of consecutive patients with SI-NENs who underwent small bowel resections were retrospectively analyzed regarding the resection technique performed.

Purpose: To evaluate whether visualization of the colon perfusion with indocyanine green near-infrared fluoroangiography (ICG-NIFA) reduces the rate of anastomotic leakage (AL) after colorectal anastomosis.

Methods: Patients who underwent elective left colectomy, including all procedures involving the sigmoid colon and the rectum with a colorectal or coloanal anastomosis, were retrospectively analyzed for their demographics, operative details, and the rate of AL. Univariate and multivariate analyses were used to compare patients with and without ICG-NIFA-based evaluation.

Backround: The influence of postoperative morbidity on survival after potentially curative resection for pancreatic ductal adenocarcinoma (PDAC) remains unclear.

Methods: Medline, Web of Science and Cochrane Library were searched for studies reporting survival in patients with and without complications, defined according to the Clavien-Dindo classification, after primary, potentially curative resection for pancreatic cancer followed by adjuvant treatment. Meta-analysis was performed using a random-effects model.

Introduction: The impact of bacterobilia on postoperative surgical and infectious complications after partial pancreaticoduodenectomy (PD) is still a matter of debate.

Methods: All patients undergoing PD with and without a preoperative biliary drainage (PBD) with complete information regarding microbial bile colonization were included. Logistic regression was applied to assess the influence of bacterobilia on postoperative outcome.

Backround: C-reactive protein (CRP) and procalcitonin (PCT) have shown to be reliable predictors of inflammatory complications and anastomotic leak after colorectal surgery. Their predictive value after partial pancreaticoduodenectomy (PD) remains unclear.

Materials And Methods: All consecutive pancreaticoduodenectomies (2009-2018) at our hospital were included.

Background: Historical data indicate that surgical resection may benefit select patients with metastatic gastric and gastroesophageal junction cancer. However, randomized clinical trials are lacking. The current RENAISSANCE trial addresses the potential benefits of surgical intervention in gastric and gastroesophageal junction cancer with limited metastases.

Background And Purpose: A 2011 metaanalysis demonstrated no difference in postoperative complications between pancreatogastrostomy and pancreaticojejunostomy after pancreaticoduodenectomy with the limitation of heterogeneity among the analysed studies. The present study compares postoperative complications after duct-to-mucosa pancreaticojejunostomy with a modified binding purse-string-mattress sutures pancreatogastrostomy in a teaching hospital.

Methods: One-hundred consecutive pancreaticoduodenectomies were reconstructed either by pancreaticojejunostomy (n = 50, 2004-2008) or modified pancreatogastrostomy (n = 50, 2008-2011).
