Background: Red blood cell transfusions (RBCT) remain a concern for patients undergoing hepatectomy. The effect of tranexamic acid (TXA), an anti-fibrinolytic, on receipt of RBCT in colorectal liver metastases (CRLM) resection was examined.

Methods: Hepatectomies for CRLM over 2009-2014 were included.

Background: Arterial lactate is frequently monitored to indicate tissue hypoxia and direct therapy. We sought to determine whether early post-hepatectomy lactate (PHL) is associated with adverse outcomes and define factors associated with PHL.

Methods: Hepatectomy patients at a single institution from 2003 to 2012 with PHL available were included.

Background: Perioperative red blood cell transfusions (RBCTs) are common in patients undergoing partial hepatectomy. We sought to explore the relationship between RBCTs and posthepatectomy perioperative outcomes in the contemporary surgical era.

Methods: We reviewed all patients undergoing partial hepatectomy from 2003 to 2012.

Background: Perioperative red blood cell transfusion (RBCT) remains common after liver resection and carries risk of increased morbidity and worse oncologic outcomes. We sought to assess the factors associated with perioperative RBCT after hepatectomy with a focus on intraoperative hemodynamics.

Methods: We performed a retrospective review of our prospective hepatectomy database, supplemented by a review of anesthetic records of all patients undergoing hepatectomy with hemodynamic monitoring (arterial and central venous pressures [CVP]) from 2003-2012.

Introduction: Portal pedicle clamping (PPC) may impact micro-metastases' growth. This study examined the association between PPC and survival after a hepatectomy for colorectal liver metastases (CRLM).

Methods: A matched cohort study was conducted on hepatectomies for CRLM at a single institution (2003-2012).

Background: Non-steroidal anti-inflammatory drugs (NSAIDs) are used commonly for postoperative analgesia but can potentially impair healing. Their effect on pancreaticoduodenectomy (PD) outcomes is unknown. We sought to examine the impact of early postoperative NSAIDs on pancreatic fistula (PF) after PD.

Background: Red blood cell transfusions (RBCTs) are associated with cancer recurrence following resection of colorectal cancer. Their impact after colorectal liver metastases (CRLM) resection remains debated. We sought to explore the association between perioperative RBCT and oncologic outcomes following resection of CRLM.

Objectives: Reports on the sensitivity and accuracy of contrast-enhanced helical computed tomography (HCT) in the preoperative evaluation of colorectal liver metastases (CLM) have been conflicting. Few studies have controlled for and reported on the time interval between HCT and eventual surgery.

Methods: A multi-institution, retrospective review of consecutive patients who underwent hepatic resection for CLM from January 1999 to September 2004 was conducted.

Background: Substantial blood loss and the requirement for blood transfusion remain major considerations for hepatic surgeons. We analysed the impact of a systematic protocol aimed at reducing intraoperative blood loss and homologous blood (HB) transfusion associated with hepatic resection.

Methods: Prospective clinical data were collected from 151 elective liver resections performed during the period between 1980 and 1999.

Background: Two distinct genetic mutational pathways characterized by either chromosomal instability or high-frequency microsatellite instability (MSI-H) are currently recognized in the pathogenesis of colorectal cancer (CRC). Recently, it has been shown that patients with primary CRC that displays MSI-H have a significant, stage-independent, multivariate survival advantage. Untreated CRC hepatic metastases are incurable and are associated with a median survival of 4 to 12 months.

Introduction: With the improved quality and widespread availability of diagnostic abdominal imaging, incidental intra-abdominal lesions (incidentalomas) are being increasingly identified. Our objective was to characterize the clinical features of asymptomatic patients with incidentally discovered pancreatic lesions and to assess the accuracy of preoperative radiologic diagnosis against the final histologic diagnosis.

Methods: This cohort study is based on prospectively collected data from a surgical pancreatic database.

Background And Objectives: A minimum number of lymph nodes must be assessed for accurate diagnosis of stage II colon cancer. We assessed number of lymph nodes retrieved, pathological ultra-staging, and outcome in stage II colon cancer.

Materials And Methods: Consecutively treated patients with stage II colon cancer were identified.

Background: The diverse natural history of renal cell carcinoma (RCC) includes metastases to the pancreas, a very unusual site for distant spread of other cancers. Considering the relatively indolent behavior of some cases of metastatic RCC, pancreatic resection is offered to select patients.

Methods: We reviewed the records of patients at three affiliated university hospital centers who had prior nephrectomy for RCC and subsequent pancreatic resection of metastases.

Background: Optimal treatment of localized colorectal cancer (CRC) depends on accurate retrieval and assessment of lymph nodes (LN) in the resected specimen.

Methods: Formal CE, informal opinion leadership and reinforcing strategies aimed at pathologists and surgeons to improve LN assessment were implemented.

Results: In the pre-intervention period a median of 8 lymph nodes were assessed in making a designation of Stage II CRC (n = 115).
