Morbidity following thyroid and parathyroid surgery: Results from key performance indicator assessment at a high-volume centre in New Zealand.

ANZ J Surg 2021 09 17;91(9):1804-1812. Epub 2021 Aug 17.

North Shore Hospital, Waitemata District Health Board, Auckland, New Zealand.

Background: Complications following thyroid/parathyroid surgery include recurrent laryngeal nerve (RLN) injury, hypocalcaemia and return to theatre for haematoma evacuation. Rates of these form the basis of key performance indicators (KPI). An endocrine database, containing results from 1997, was established at the North Shore Hospital in Auckland, New Zealand. We aimed to measure complication rates by procedure (thyroid and parathyroid), explore a temporal change in our unit and compare our results against international literature.

Methods: A retrospective review of the database between July 1997 and February 2020 was performed. The results for each KPI were analysed in total and over consecutive time periods. A review of the literature was carried out to find international complication rates for comparison. A cumulative sum (CUSUM) analysis was performed to give visual feedback on performance.

Results: There were 1062 thyroidectomies and 336 parathyroidectomies from July 1997 to February 2020. Thyroid surgery results found rates of temporary/permanent RLN injury of 1.9%/0.3%, temporary/permanent hypocalcaemia of 22.3/2.5%, and return to theatre for haematoma evacuation of 1.1%. Parathyroid surgery results were, temporary RLN injury of 0.8% (no permanent injury), temporary/permanent hypocalcaemia of 1.7%/0.4%, and return to theatre for haematoma evacuation of 0.3%. CUSUM analysis found KPI results to be comparable with international literature.

Conclusion: Our unit's KPI results are comparable to published results in the literature. The use of this clinical database will help in future monitoring of performance and help drive improvement in the service. Embedding prospective data collection as routine practice allows for continuous improvement for the unit.

Difficult diagnosis and management of a complicated Nellix graft infection.

J Vasc Surg Cases Innov Tech 2021 Sep 20;7(3):417-420. Epub 2021 May 20.

Department of Vascular Surgery, Auckland City Hospital, Auckland, New Zealand.

An 81-year-old man, with a complex vascular surgical history, presents with sepsis from an infected Nellix stent-graft. He required an urgent laparotomy, explantation of the graft, and extra-anatomical repair. Although now widely used for this indication, the preoperative 18F-fluorodeoxyglucose positron emission tomography/computed tomography was nondiagnostic for his stent-graft infection. We describe our management of a complicated Nellix graft infection and discuss the utility of positron emission tomography/computed tomography for stent-graft infections.

Delayed presentation of an iatrogenic, traumatic brachio-brachial fistula.

Trauma Case Rep 2021 Apr 18;32:100438. Epub 2021 Feb 18.

Vascular Department, Auckland City Hospital, ADHB, New Zealand.

Iatrogenic arteriovenous fistulae are rare occurrences after venepuncture, line placement or trauma. Presentations and symptoms can vary but they are usually identified soon after the causative injury due to the development of a visible, palpable, and pulsatile lump that can be concerning for patients. We describe the presentation and management of an unusual case of delayed presentation of an iatrogenic, traumatic brachio-brachial fistula.

A novel biopolymer device fabricated by 3D printing for simplifying procedures of pancreaticojejunostomy.

Mater Sci Eng C Mater Biol Appl 2019 Oct 21;103:109786. Epub 2019 May 21.

Department of General Surgery, Fujian Medical University Union Hospital, Fuzhou 350001, PR China. Electronic address:

The purpose of our research was to verify the feasibility and effectiveness of a novel three-dimensional printed biopolymer device (3DP-BPD) for duct-to-mucosa pancreaticojejunostomy (PJ) in minipigs. Polylactic acid (PLA) was selected as the raw materials for 3DP-BPD. Three components of a 3DP-BPD were designed and manufactured: hollow stent, supporting disk, and nut. A pancreatic duct dilation model was developed in six minipigs. After 4 weeks, minipigs underwent operations with duct-to-mucosa PJ using 3DP-BPD. The operation time and postoperative complications were analyzed. The anastomotic sites were evaluated grossly 4 weeks and 24 weeks after PJ, and the histological evaluation of anastomotic sites was performed 24 weeks after PJ. The operation time of six stitches duct-to-mucosa PJ was 9.1 ± 1.7 min. All minipigs survived without any adverse events like postoperative pancreatic fistula (POPF). Serum C reactive protein (CRP) and procalcitonin (PCT) levels were normal, and the anastomotic sites were connected tightly on gross observation and touch at 4 weeks and 24 weeks. Histological examinations indicated that the tissues were continuous between the pancreas and the jejunum. The use of 3DP-BPD did not increase the risk of severe local inflammation and POPF. 3DP-BPD used for duct-to-mucosa PJ is more convenient and clinically feasible for pancreatoenteric reconstruction.

Sugar-sweetened beverage intake and serum testosterone levels in adult males 20-39 years old in the United States.

Reprod Biol Endocrinol 2018 Jun 23;16(1):61. Epub 2018 Jun 23.

The First Division in the Department of Endocrinology, Guangdong General Hospital, Guangdong Academy of Medical Sciences, 106th of Zhongshan Er Road, Guangzhou, 510080, China.

Background: This population-based study was designed to investigate whether consumption of sugar-sweetened beverages (SSB) is associated with lower serum total testosterone concentration in men 20-39 years old.

Methods: All data for this study were retrieved from the National Health and Nutrition Examination Survey (NHANES) 2011-2012. The primary outcome was serum testosterone concentration, and main independent variable was SSB intake. Other variables included age, race/ethnicity, poverty/income ratio, body mass index (BMI), serum cotinine, heavy drinking, and physical activity.

Results: Among all subjects (N = 545), 486 (90.4%) had normal testosterone levels (defined as ≥231 ng/dL) and 59 (9.6%) had low testosterone levels (defined as < 231 ng/dL). Multivariate logistic regression revealed the odds of low testosterone was significantly greater with increasing SSB consumption (Q4 [≥442 kcal/day] vs. Q1 [≤137 kcal/day]), adjusted odds ratio [aOR] = 2.29, p = 0.041]. After adjusting for possible confounding variables, BMI was an independent risk factor for low testosterone level; subjects with BMI ≥ 25 kg/m had a higher risk of having a low testosterone level than those with BMI < 25 kg/m (aOR = 3.68, p = 0.044).

Conclusion: SSB consumption is significantly associated with low serum testosterone in men 20-39 years old in the United States.

Objective: To investigate the correlation between liver and skeletal muscle fat contents and insulin resistance in obese individuals with different levels of glucose tolerance.

Methods: RESULTS: Ten non-obese individuals with normal glucose tolerance (NGT), 9 obese individuals with NGT, and 7 obese individuals with impaired glucose tolerance (IGT) were enrolled in this study. All the participants were examined for insulin sensitivity by hyperinsulinemic-euglycemic clamp and for liver and skeletal muscle fat accumulation quantified by proton magnetic resonance spectroscopy (1H MRS). The data were collected from the subjects including somatometric measurements, fasting plasma glucose, 2-h plasma glucose (2hPG), fasting insulin, and blood biochemistry. Linear correlation analysis and multiple linear stepwise regression analysis were used to analyze the relationship between ectopic fat accumulation and insulin resistance.

Results: The glucose infusion rates (GIR, presented as the M value) differed significantly among IGT-obese (3.95∓1.66 mg·kg·min), NGT-obese (6.14∓1.90 mg·kg·min) and NGT-non-obese (8.78∓2.46 mg·kg·min) groups (P<0.05). The 3 groups also showed significant differences in liver fat contents [(15.23∓3.09)%, (6.25∓0.38)%, and (1.89∓0.90)%, respectively, P<0.05] and intramyocellular lipids in the tibialis anterior (2.69∓0.95, 2.61∓1.45, and 1.54∓0.66 mmol/kg, respectively, P<0.05). Linear analysis revealed that liver fat content, but not skeletal muscle fat content, was significantly correlated with the M value. Multiple linear stepwise regression analysis using M value as the dependent variable (Y) revealed that liver fat content (X) was an independent factor inversely correlated with the M value (regression equation: Y=-30.562X+9.007, R=0.717, P<0.01).

Conclusions: Liver fat accumulation, but not skeletal muscle fat accumulation, is correlated with insulin resistance and impaired glucose metabolism.

Optimal Dosing of Botulinum Toxin for Treatment of Chronic Anal Fissure: A Systematic Review and Meta-Analysis.

Dis Colon Rectum 2016 Sep;59(9):886-94

1 Faculty of Medical and Health Sciences, The University of Auckland, Auckland, New Zealand 2 Department of Surgery, The University of Auckland, Auckland, New Zealand.

Background: Chronic anal fissures are associated with significant morbidity and reduced quality of life. Studies have investigated the efficacy of botulinum toxin with variable results; thus, there is currently no consensus on botulinum toxin dose or injection sites.

Objective: This study aimed to systematically analyze trials studying the efficacy of botulinum toxin for treatment of chronic anal fissure to identify an optimum dosage and injection regimen.

Data Sources: A comprehensive review of the literature was conducted according to PRISMA guidelines. PubMed/Medline, Embase, Scopus, and the Cochrane Library were searched from inception to June 2015.

Study Selection: All clinical trials that investigated the efficacy of botulinum toxin for chronic anal fissure were selected according to specific criteria.

Intervensions: The interventions used were various doses of botulinum toxin.

Outcome Measures: Clinical outcomes, dosage, and injection site data were evaluated with weighted pooled results for each dosage and 95% confidence intervals.

Results: There were 1158 patients, with 661 in botulinum toxin treatment arms, from 18 clinical trials included in this review. The outcomes of interest were 3-month healing, incontinence, and recurrence rates. Meta-regression analysis demonstrated a small decrease in healing rate (0.34%; 95% CI, 0-0.68; p = 0.048) with each increase in dosage, a small increase in incontinence rate (1.02 times; 95% CI, 1.0002-1.049; p = 0.048) with each increase in dosage and a small increase in recurrence rate (1.037 times; 95% CI, 1.018-1.057; p = 0.0002) with each increase in dosage. The optimum injection site could not be determined.

Limitations: This study was limited by weaknesses in the underlying evidence, such as variable quality, short follow-up, and a limited range of doses represented.

Conclusions: Fissure healing with lower doses of botulinum toxin is as effective as with high doses. Lower doses also reduce the risk of incontinence and recurrence in the long term.
