Comparison of lipid-normalised concentrations of persistent organic pollutants (POPs) between serum and adipose tissue.

Human biomonitoring of persistent organic pollutants (POPs) is typically based on serum analysis and for comparison and modelling purposes, data are often normalised to the lipid content of the serum. Such approach assumes a steady state of the compound between the serum lipids and for example lipid-rich adipose tissue. Few published data are available to assess the validity of this assumption.

Early Experience with Laparoscopic Frey Procedure for Chronic Pancreatitis: a Case Series and Review of Literature.

The Frey procedure has been demonstrated to be an effective surgical technique to treat patients with painful large duct chronic pancreatitis. More commonly reported as an open procedure, we report our experience with a minimally invasive approach to the Frey procedure. Four consecutive patients underwent a laparoscopic Frey procedure at our institution from January 2012 to July 2015.

Synchronous colorectal liver metastases in pregnancy and post-partum.

Background: Metastatic colorectal cancer (mCRC) in pregnancy and post-partum is rare, but represents significant diagnostic and therapeutic challenges for clinicians. A multidisciplinary team (MDT) approach is essential. This study reports the first series in the Australasian literature, describing our experience with and management of pregnant and post-partum patients diagnosed with synchronous colorectal liver metastases (sCRLM).

A review of natural orifice translumenal endoscopic surgery (NOTES) for intra-abdominal surgery: experimental models, techniques, and applicability to the clinical setting.

Objective: Evaluation of models, techniques, outcomes, pitfalls, and applicability to the clinical setting of natural orifice translumenal endoscopic surgery (NOTES) for performing intra-abdominal surgery through a systematic review of the literature.

Summary Background Data: NOTES has attracted much recent attention for its potential to allow traditional surgical procedures to be performed entirely through a natural orifice. Amid the excitement for potentially scar-free surgery and abolishment of dermal incision-related complications, the safety and efficacy of this new surgical technology must be evaluated.

Postoperative ERCP versus laparoscopic choledochotomy for clearance of selected bile duct calculi: a randomized trial.

Objective: Prospectively evaluate whether for patients having laparoscopic cholecystectomy with failed trans-cystic duct clearance of bile duct (BD) stones they should have laparoscopic choledochotomy or postoperative endoscopic retrograde cholangiography (ERCP).

Summary Background Data: Clinical management of BD stones found at laparoscopic cholecystectomy in the last decade has focused on pre-cholecystectomy detection with ERCP clearance in those with suspected stones. This clinical algorithm successfully clears the stones in most patients, but no stones are found in 20% to 60% of patients and rare unpredictably severe ERCP morbidity can result in this group.

Jaundice due to extrabiliary gallstones.

Objective: Cholecystectomy is one of the most common general surgical procedures performed today. The laparoscopic approach is beneficial to patients in terms of length of stay, postoperative pain, return to work, and cosmesis. Some drawbacks are associated with the minimal access form of cholecystectomy, including an increased incidence of common bile duct injuries.
