Perioperative and oncologic outcomes of minimally invasive liver resection for colorectal metastases: A case-control study of 130 patients.

Background: Our aim was to compare the perioperative and oncologic outcomes of open liver resection and minimally invasive liver resection in the management of colorectal liver metastases.

Methods: Patients who underwent minimally invasive liver resection for colorectal liver metastases between January 2006 and June 2015 at a single center were identified and matched by extent of resection to consecutive open liver resection patients from the same period. Clinicopathologic characteristics, perioperative data, recurrence, and survival outcomes were collected and analyzed based on intention-to-treat.

Prediction of intraoperative transfusion requirements during orthotopic liver transplantation and the influence on postoperative patient survival.

Background: Predicting blood product transfusion requirements during orthotopic liver transplantation (OLT) remains difficult. Our primary aim in this study was to determine which patient variables best predict recipient risk for large blood transfusion requirements during OLT. The secondary aim was to determine whether the amount of blood products transfused during OLT impacted patient survival.

Jejunal cavernous lymphangioma.

Cavernous lymphangiomas are usually identified in infants and children with the majority of lesions found around the head and neck, trunk or extremities. Tumours affecting the intra-abdominal organs are rare. The authors report a case of small bowel cavernous lymphangioma arising within the jejunum of a 34-year-old woman presenting with dyspnoea and anaemia, and review the existing literature relating to this uncommon tumour.

Is impaired hepatic arterial buffer response a risk factor for biliary anastomotic stricture in liver transplant recipients?

Background: Blood flow to the liver is partly maintained by the hepatic arterial buffer response (HABR), which is an intrinsic autoregulatory mechanism. Temporary clamping of the portal vein (PV) results in augmentation in hepatic artery flow (augHAF). Portal hyperperfusion impairs HAF due to the HABR in liver transplantation (LT).

Management of suspected pancreatic cystic neoplasms based on cyst size.

Background: Evaluation and management of cystic pancreatic neoplasms remain problematic. International consensus guidelines have advised resection for lesions greater than 3 cm.

Methods: We reviewed our prospective pancreatic cystic neoplasm database for outcomes based on a cyst size of 3 cm.

Long-term outcome of biliary reconstruction for bile duct injuries from laparoscopic cholecystectomies.

Background: Major bile duct injuries remain a potentially devastating complication after laparoscopic cholecystectomy. A retrospective review was conducted of patients who underwent a biliary-enteric reconstruction of a biliary injury to assess their long-term outcome.

Methods: Retrospective review of bile duct injury database from January 1990 to December 2005.

Natural history of indeterminate pancreatic cysts.

Background: The optimal treatment for incidental asymptomatic pancreatic cysts is not known. The purpose of this study was to determine whether nonmucinous cysts by cyst-aspiration analysis can be observed safely.

Methods: A prospective protocol was initiated in September of 1999 for all suspected cystic neoplasms.

Cystadenoma and cystadenocarcinoma of the liver: a single center experience.

Background: Biliary cystadenomas and cystadenocarcinomas comprise 5% of cystic lesions in the liver. Cystadenomas are often incorrectly diagnosed as simple cysts, which results in inadequate therapy. Recurrence and possible malignant transformation are consequences of incomplete excision.

Management of failed biliary repairs for major bile duct injuries after laparoscopic cholecystectomy.

Background: Many bile injuries are managed without referral to tertiary centers. Management of patients referred for a primary repair, or after a failed repair, was reviewed to compare outcomes.

Study Design: Retrospective review of data collected in prospective database.

Leukocyte reduction during orthotopic liver transplantation and postoperative outcome: a pilot study.

Study Objective: To investigate the effect of intraoperative leukocyte reduction of administered blood products on the incidence of acute cellular rejection and postoperative patient outcome.

Design: Prospective, nonrandomized, historical control study.

Setting: Academic tertiary medical center.

Gallbladder disease: an update on diagnosis and treatment.

This paper reviews the clinical presentation of gallstone disease, acalculous cholecystitis, biliary dyskinesia, and gallbladder cancer, as well as how to make best use of current diagnostic and treatment methods, particularly ultrasonography, cholescintigraphy, laparoscopic cholecystectomy, and endoscopic retrograde cholangiopancreatography.

Hepatic abscess after liver transplantation: 1990-2000.

Background: Infections following solid-organ transplants are a major cause of morbidity and mortality. Few studies have reported the complications of hepatic abscesses.

Methods: This investigation consisted of a retrospective chart review of all solid-organ transplant recipients from 1990 to 2000.

The long-term survival and causes of death in patients who survive at least 1 year after liver transplantation.

Background: The purpose of this study was to examine the long-term survival and causes of death in patients who survive the first year after liver transplantation.

Methods: The focus of the analysis was 433 patients who survived for at least 1 year after liver transplantation between November 1, 1984, and December 31, 2001. A total of 586 liver transplants were performed in 542 patients during this time period.

Prospective preoperative determination of mucinous pancreatic cystic neoplasms.

Background: Optimal management of pancreatic cystic neoplasms includes identification and resection of mucinous neoplasms. This study was performed to assess the accuracy of preoperative variables in determining a mucinous lesion.

Methods: Patients referred for a cystic neoplasm were prospectively assessed by presenting symptoms, blinded radiologic review, and endoscopic ultrasound-guided cyst aspirate analysis.

Intestinal malrotation: a rare but important cause of bowel obstruction in adults.

Purpose: Complications of intestinal malrotation are familiar to pediatric surgeons but are rarely encountered by those caring strictly for adults. The aim of this study was to review our experience with disorders of intestinal rotation in adult patients and to emphasize the clinical presentation, radiographic features, and results of surgical treatment.

Methods: Ten adult patients (mean age, 42 (range, 22-73) years) with complications of intestinal malrotation were identified by review of department records.
