Transversus abdominis plane blocks with liposomal bupivacaine after open major hepatectomy is associated with reduced early patient-reported pain scores and opioid administration.

Background: Opioid overprescription can contribute to suboptimal patient outcomes. Surgeon-performed transversus abdominis plane blocks appear to be associated with pain reduction. We compared the analgesic efficacy of surgeon-performed transversus abdominis plane blocks for major hepatectomy with or without concurrent neuraxial analgesia.

Outcomes following resection of intrahepatic cholangiocarcinoma.

Objectives: The aim of this analysis was to examine prognostic features and outcomes in patients undergoing resection for intrahepatic cholangiocarcinoma (ICC).

Methods: A retrospective chart review was performed in all patients who underwent R0 or R1 resection for primary ICC between 1995 and 2011. Clinical data were abstracted and statistical analyses were conducted in the standard fashion.

Outcome of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy on patients with diaphragmatic involvement.

Purpose: The purpose of this study is to assess the short-term morbidity and mortality in patients undergoing cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) with diaphragmatic involvement.

Methods: All patients undergoing CRS/HIPEC at a tertiary care institution from April 2007 to October 2013 were retrospectively reviewed. Patients with diaphragmatic disease (Group 1) were compared to those who did not (Group 2).

Differences in surgical outcomes between hepatitis B- and hepatitis C-related hepatocellular carcinoma: a retrospective analysis of a single North American center.

Objective: Compare surgical outcomes for hepatitis B virus (HBV)-hepatocellular carcinoma (HCC) versus hepatitis C virus (HCV)-hepatocellular carcinoma (HCC).

Background: HCC is the second leading cause of death from cancer worldwide and is associated with hepatitis virus infection in 80% of cases.

Methods: Between 1997 and 2011, 1008 patients with hepatitis B (HBV, n = 431) or hepatitis C (HCV, n = 577) underwent resection (n = 567) or transplantation (n = 441).

Cytoreductive surgery with or without hyperthermic intraperitoneal chemotherapy in patients with peritoneal hepatocellular carcinoma.

Background And Objectives: The benefit of Sorafenib is not well described in patients with peritoneal hepatocellular carcinoma (HCC). Although cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) have shown favorable outcomes in certain malignancies, their role in peritoneal HCC remains unknown. We present a series of patients with peritoneal HCC treated with CRS +/- HIPEC and evaluate their clinicopathologic characteristics and outcomes.

Actual 10-year survival following hepatectomy for hepatocellular carcinoma.

Objectives: This study was conducted to compare 10-year survivors with patients who survived <10 years in a large Western series of patients submitted to hepatectomy for hepatocellular carcinoma (HCC).

Methods: A retrospective review of a series of hepatic resections conducted in a referral centre for HCC between January 1987 and October 2002 was conducted.

Results: A total of 176 patients were analysed.

Genitourinary resection at the time of cytoreductive surgery and heated intraperitoneal chemotherapy for peritoneal carcinomatosis is not associated with increased morbidity or worsened oncologic outcomes: a case-matched study.

Background: Cytoreductive surgery (CRS) with heated intraperitoneal chemotherapy (HIPEC) has gained acceptance in the treatment of peritoneal carcinomatosis with reported morbidity and mortality rates of 27-56 and 0-11 %, respectively. The safety and oncologic outcome of genitourinary repair at the time of CRS and HIPEC remains unclear.

Methods: We identified 170 patients who underwent CRS-HIPEC at our institution between July 2007 and August 2011 with a minimum follow-up of 6 months.

Outcomes for cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in the elderly.

Background: Cytoreductive surgery (CRS) with heated intraperitoneal chemotherapy (HIPEC) has gained acceptance in the treatment of peritoneal carcinomatosis (PC) with reported morbidity and mortality rates of 27-56% and 0-11% respectively. The safety and outcome of such major operation in the elderly remains unclear. We report our experience at a high volume tertiary center.

Intraductal polypoid lipid-rich neuroendocrine tumor of the pancreas with entrapped ductules: case report and review of the literature.

Pancreatic neuroendocrine tumors of the main pancreatic duct are rare and usually small due to symptoms of pancreatic duct obstruction. We present a case of a large (3 cm), well-differentiated (G1) lipid-rich polypoid neuroendocrine tumor of the pancreas completely occluding the main pancreatic duct with non-neoplastic-entrapped ductules and CK19 positivity. Clinical, radiological, gross, microscopic, immunohistochemical, and ultrastructural findings are discussed.

Impact on quality of life after pancreatoduodenectomy: a prospective study comparing preoperative and postoperative scores.

Introduction: Few studies compare the direct impact of pancreatoduodenectomy (PD) on the patient's quality of life (QOL). The effect of PD in QOL, comparing the preoperative vs. postoperative status, was analyzed.

Transition from a low: to a high-volume centre for bile duct repair: changes in technique and improved outcome.

Background: Improvements in bile duct injury repairs have been shown in centres with specialized surgeons. The aim of the present study was to demonstrate the temporal change in the pattern of referral, technical variation associated with repair and long-term outcome of bile duct injuries at a tertiary referral centre in Mexico City.

Methods: A retrospective case note review was performed.

Liver segment IV hypoplasia as a risk factor for bile duct injury.

Introduction: Bile duct injury remains constant in the era of laparoscopic cholecystectomy and misidentification of structures remains one of the most common causes of such injuries. Abnormalities in liver segment IV, which is fully visible during laparoscopic cholecystectomy, may contribute to misidentification as proposed herein.

Methods: We describe the case of a 36-year-old female who had a bile duct injury during a laparoscopic cholecystectomy where the surgeon noticed an unusually small distance between the gallbladder and the round ligament.

Components-separation technique for closure of transverse non-midline abdominal wall incisional hernia.

The components-separation technique was originally described and has been popularised for the treatment of large midline hernias. In this report, we indicate that components separation can also be applied for the closure of transverse non-midline hernias, provided the largest diameter of the defect (i.e.

Pancreaticoduodenectomy in a Latin American country: the transition to a high-volume center.

Objective: To analyze data in a single institution series of pancreaticoduodenectomies (PD) performed in a 7-year period after the transition to a high-volume center for pancreatic surgery.

Background: PD has developed dramatically in the last century. Mortality is minimal yet complications are still frequent (around 40%).

[Pancreatoduodenectomy: results in a large volume center].

Objective: Analyze the experience with pancreaticoduodenectomy (PD) at the INCMNSZ.

Background Data: PD has become a popular procedure in hospitals throughout the USA and Europe in the last 25 years, where mortality is < 5% y morbidity remains around 40%. Nonetheless there are very few reports on PD in Latin America.

[Surgical techniques in liver transplantation].

Liver transplantation (LT) is probably the biggest surgical aggression that a patient can endure. It was considered only as a last option in the era of experimental LT, yet it evolved into the definitive treatment for some types of acute and chronic end stage liver disease. In terms of technique LT is the most complex of all types of transplantations.
