How does thyroidectomy for benign thyroid disease impact upon quality of life? A prospective study.

BACKGROUND: Choosing which patients to recommend surgery for benign thyroid conditions can be difficult due to the subjective nature of compressive thyroid and hormonal symptoms. The aim of this prospective study was to analyse changes in quality of life (QOL) following thyroid surgery using a validated disease-specific assessment tool, the thyroid-related patient-reported outcome (ThyPRO) questionnaire. METHODS: Participants undergoing elective thyroid surgery for benign conditions were recruited. Patient demographics and clinical data were collected. ThyPRO consists of 85 questions grouped into 13 physical, mental and social symptom domains. Patients completed a ThyPRO questionnaire pre-operatively and at 6 weeks and 6 months post-operatively. ThyPRO items were scored according to protocol to produce 13 subscales. Repeated measures linear models with no random effects were performed using data for each outcome. RESULTS: Results were available for a total of 72 patients. The sample was predominately female (n = 63, 88%) with average age 49.8 years. The majority of patients underwent surgery for multi-nodular goitre. At 6 weeks post-operatively, significant improvement was demonstrated in the goitre, hypothyroid, hyperthyroid and anxiety symptom domains. At 6 months post-operatively, significant improvement was demonstrated in all but four domains. No domains demonstrated significant increase in impairment post-operatively. CONCLUSION: Patients had significant improvement in nine of 13 symptom domains following surgery. Patients did not experience a negative impact on QOL following surgery. Further studies with larger patient cohorts may be able to identify potential pre-operative predictive factors for a post-operative improvement in QOL for benign thyroid disease.

Treatment of colonoscopic perforation: outcomes from a major single tertiary institution.

BACKGROUND: The use of colonoscopy has been increasing in Australia. This case series describes management and outcomes of colonoscopic perforation managed by a single tertiary referral unit. METHODS: An analysis of 13 years (2003-2015) of prospectively collected data on patients who had a colonoscopic perforation and were managed by the colorectal unit at a single tertiary referral centre was performed. Main outcomes were time of diagnosis, modality of management, time to theatre, length of stay, cost of admission and complications. RESULTS: Sixty-two patients had perforations (median age of 69 years). Thirty-eight (61.2%) patients had their colonoscopy performed in another institution. The incidence rate decreased to 0.37 perforations per 1000 colonoscopies within Western Health. Overall, diagnostic colonoscopies accounted for 56% of perforations and perforations were likely to occur in the left colon (P = 0.006). Fifty-one (82%) patients underwent surgery during their admission, with 24% of these being laparoscopic procedures. An earlier diagnosis was associated with significantly less intra-abdominal contamination. Gross peritoneal contamination was more likely to be associated with the decision to form a stoma (37%, n = 19, P = 0.04). Thirty-day mortality was 1.6% (n = 1). CONCLUSIONS: Colonoscopic perforations occur in experienced hands and may have serious implications. We demonstrated a difference in patterns of injury between therapeutic and diagnostic colonoscopies. Those who have an earlier diagnosis are less likely to have severe intra-abdominal contamination requiring a stoma formation.

Systematic differences between ultrasound and pathological evaluation of thyroid nodules: a method comparison study.

BACKGROUND: The size of thyroid nodules as measured by ultrasound (ultrasound size, USS) is routinely used in clinical decision-making. Reports of discrepancy between USS and pathological size (PS) evaluation have not analysed their systematic differences. The objective of this study was to uncover the lack of agreement (bias) between USS and PS measurements. METHODS: A retrospective study was performed on 121 patients who had a total or hemi-thyroidectomy for a solitary nodule. Ordinary least product regression was used to detect and distinguish constant and proportional bias in unidimensional size measurements between USS and PS evaluation. Three-dimensional volume measurements were compared in a subgroup of 31 patients. Pre-specified acceptable limits of interchange were defined as 20% difference. RESULTS: Ordinary least product regression demonstrated no constant or proportional bias between the two methods; regression equation: USS = (0.863) + (1.040) × PS. When nodules were grouped by size, discrepancies between the two methods were observed in nodules <10 mm (P = 0.004). However, potential overtreatment of patients with USS >10 mm but PS <10 mm only accounted for 4.1% of total patients. Subgroup analysis of volume measurements showed no bias between USS and PS evaluation. CONCLUSIONS: USS and PS measurements were interchangeable, as there was no evidence of constant or proportional bias between the two measurements. However, USS may misclassify the size for smaller nodules and potentially lead to unnecessary workup and treatment. Discrepancy in size measurements between USS and PS should be taken into account in clinical practice, particularly in smaller nodules.

Prospective randomized trial of laparoscopic Nissen fundoplication with anterior versus posterior hiatal repair: late outcomes.

BACKGROUND: The technique used for hiatal closure in laparoscopic Nissen fundoplication might have an impact on the risk of postfundoplication dysphagia and hiatal herniation. In 1997, we commenced a randomized trial to evaluate the impact of anterior versus posterior hiatal repair techniques on these outcomes. In the present study, we evaluated the 10-year outcomes from this trial. METHODS: A total of 102 patients were randomized to undergo laparoscopic Nissen fundoplication with either anterior (47 patients) or posterior (55 patients) repair of the diaphragmatic hiatus. Outcomes were assessed using standardized clinical assessment scores that evaluated reflux symptoms, dysphagia, and satisfaction with the outcome following surgery. RESULTS: Clinical outcomes 10 years after surgery were available for 93% of patients, and outcome scores were obtained for 43 patients in each group. Patients undergoing anterior hiatal repair were less likely to report dysphagia for lumpy solid foods (14.0% vs. 39.5%, p = 0.01), although there were no significant differences in dysphagia outcomes for six other dysphagia assessment scores. There were no differences between the two groups for reflux symptoms, medication use, and overall satisfaction with the outcome of surgery. CONCLUSIONS: At the 10-year follow-up, the outcomes for the two groups were similar. Anterior hiatal repair is an acceptable technique for hiatal closure during laparoscopic Nissen fundoplication.
