Correlation of pathological examination with indocyanine green (ICG) intensity gradients: a prospective study in patients with liver tumor.

Background: Intraoperative indocyanine green (ICG) fluorescence imaging has been shown to be a new and innovative way to illustrate the optimal resection margin in hepatectomy for hepatocellular carcinoma. This study investigated its accuracy in resection margin determination by looking into the correlation of ICG intensity gradients with pathological examination results of resected specimens.

Methods: This was a prospective, single-center, non-randomized controlled study.

Impact of Three-Dimensional (3D) Visualization on Laparoscopic Hepatectomy for Hepatocellular Carcinoma.

Background: The impact of three-dimensional (3D) visualization on laparoscopic hepatectomy for hepatocellular carcinoma is largely unknown.

Methods: A retrospective review with propensity-score matched analysis of 3D and two-dimensional (2D) laparoscopic hepatectomy performed in a tertiary hepatobiliary surgery center.

Results: Since the availability of 3D laparoscopy, the proportion of laparoscopic major hepatectomies has significantly expanded (1.

Routine use of ICG to enhance operative safety in emergency laparoscopic cholecystectomy: a randomized controlled trial.

Objective: To test the hypothesis that ICG fluorescence cholangiography (ICG-FC) helps to identify critical structures during laparoscopic cholecystectomy (LC) and hence reduce biliary injuries and conversions. In LC, biliary injury and conversion often happen if the biliary anatomy is misidentified.

Methods: This was a single-center randomized controlled trial from 2017 to 2019.

Prognostic value of preoperative alpha-fetoprotein (AFP) level in patients receiving curative hepatectomy- an analysis of 1,182 patients in Hong Kong.

Background: The value of alpha-fetoprotein (AFP) as a prognostic indicator in patients with hepatocellular carcinoma (HCC) has been proposed in recent studies, but the evidence so far is still contradictory. This analysis aims to evaluate the prognostic value of preoperative AFP level in patients undergoing curative resection.

Methods: This retrospective study reviewed the prospectively collected data of all patients who underwent initial liver resection for HCC at Queen Mary Hospital during the period from March 1999 to March 2013.

Sarcopenia in pancreatic cancer - effects on surgical outcomes and chemotherapy.

Sarcopenia is found in up to 65% of pancreatic cancer patients. The definition and diagnostic methods for sarcopenia have changed over the years, and the measurement of skeletal muscle mass with cross-sectional imaging has become the most popular way of assessment, although the parameters measured vary among different studies. It is still debatable that there is an association between sarcopenia and postoperative pancreatic fistula, but most studies showed a higher risk in patients with sarcopenic obesity.

Prospective Study on Sexual Dysfunction in Male Chinese Liver Transplant Recipients.

In patients with end-stage liver disease, hypogonadism and erectile dysfunction are often seen. This study was to determine the incidence of erectile dysfunction before and after liver transplantation (LT) with correlation to change in sex hormone levels from a Chinese cohort. This prospective longitudinal study was registered with The University of Hong Kong Clinical Trials Centre (HKUCTR-1563).

Left hepatectomy in a patient with a Fontan circulation.

Patients with a Fontan circulation face the long term risk of cardiac cirrhosis and the subsequent development of hepatocellular carcinoma (HCC). A hepatectomy operation imposes significant risk on such patients as the Fontan circulation can be severely compromised. Here we present a 24-year-old woman post-Fontan operation who successfully underwent a left hepatectomy, and discuss the anaesthetic and surgical management.

Surgical management of neuroendocrine tumor-associated liver metastases: a review.

Liver metastasis is common among patients who suffer from neuroendocrine tumors (NETs). Radical surgery is the standard treatment whenever possible but there is still controversies concerning the treatment strategies such as resection of the primary, role of debulking surgery, liver transplantation (LT) and neoadjuvant or adjuvant therapies. This article aims to review the current evidence available, together with some latest updates, focusing on the surgical management.

Laparoscopic colorectal resections with and without routine mechanical bowel preparation: A comparative study.

Background: The benefit of mechanical bowel preparation (MBP) in patients undergoing laparoscopic colorectal resections remains a question. This study aimed to evaluate the effect of omitting MBP on patients undergoing laparoscopic bowel resections.

Methods: The outcomes of patients who underwent elective colorectal resections for cancer of colon and upper rectum without MBP were compared to a retrospective cohort who had MBP.

Is vocal cord asymmetry seen on transcutaneous laryngeal ultrasonography a significant predictor of voice quality changes after thyroidectomy?

Background: Vocal cord asymmetry (VCA) on laryngoscopic examination (LE) may suggest voice impairment after thyroidectomy, but LE may cause patient discomfort. We aimed to correlate the presence of postoperative VCA assessed by noninvasive transcutaneous laryngeal ultrasonography (TLUSG) with voice quality changes after thyroidectomy.

Methods: A total of 169 patients scheduled for thyroidectomy completed two validated voice symptoms questionnaires-the GRBAS (grade, roughness, breathiness, asthenia, strain) scale and the voice impairment score (VIS)-and underwent TLUSG and LE at 1 day before and 7-10 days after thyroidectomy.
