Laparoscopic and open inguinal hernia repair: Patient reported outcomes in the elderly from a single centre - A prospective cohort study

Background

With those over 65 making up over 16% of the UK's population, surgeons are counselling increasing numbers of elderly patients for hernia repair. Data is currently lacking comparing different repair methods of inguinal hernias in the elderly population with regards to patient reported outcomes.

Aim

To compare open and laparoscopic hernia repair in patients >65 years old and those <65 years old with respect to patient reported outcomes.

Method

As part of a quality assurance process patients receive a telephone consultation day 2 post procedure. This includes an optional survey with questions to quantify pain, general feeling, nausea, dizziness, drowsiness, satisfaction and vomiting since the operation. Patients were then classified into age ≥ 65 years or <65 years and subclassified into totally extraperitoneal (TEP) or open inguinal hernia repair (IHR).

Results

Data is presented from patients treated between January 2009 and August 2016, totalling those included 1167 of 2522 (55.5%). Only five patients (4.42%) reported moderate pain; in the >65 TEP group this was significantly lower (10.2% open IHR <65; 6.7% TEP <65; 12.8% open IHR >65). Patient satisfaction with the surgery was satisfied or very satisfied in all patients in all groups.

Conclusion

Time off work is not an absolute appropriate measure of return to premorbid status with respect to the elderly as a substantial number of >65 year olds have retired. We therefore present this interesting insight into patient perceptions following hernia repair by age group. Overall patients over 65 can expect the same high levels of satisfaction and low levels of pain following either technique for inguinal hernia repair as younger patients.

•

Time off work is not an appropriate measure of laparoscopic hernia repair in the over 65 year old population as the majority of this cohort is retired.

•

Dizziness and drowsiness appeared to be no more prevalent in the over 65 year age group.

•

Patient satisfaction with the surgery was satisfied or very satisfied in all patients in all groups.

•

Overall a patient of any age can expect the same high levels of satisfaction and low levels of pain with either technique.

Temporal artery biopsy in the diagnosis of giant cell arteritis: Does the end justify the means?

BACKGROUND

Early temporal artery biopsy is recommended in all patients with suspected cranial GCA (Giant Cell Arteritis) by the BSR (British Society of Rheumatology) and BHPR (British Health Professionals in Rheumatology) guidelines. This should be performed within one week ideally.

AIM

To assess ACR (American College of Rheumatology) score at presentation and whether temporal artery biopsy result affects clinical management of the clinically suspected GCA patient.

METHOD

Case records of all temporal artery biopsies performed within January 2012 until December 2014 were analysed for size and result of biopsy and this was correlated to clinical management following result.

RESULTS

129 temporal arteries were biopsied with a total of 17 positive biopsy results. 10 biopsy samples were insufficient to confirm or refute GCA. 8 patients within the biopsies negative for GCA had their prednisolone therapy stopped. 5 patients had unknown follow up, with the remainder (89, 87.3%) of the patients continued prednisolone management for treatment of GCA for at least 6 weeks.

CONCLUSION

Overall 13.2% of our biopsies were positive for GCA and 87.3% of biopsy negative patients continued prednisolone therapy on clinical grounds. In the face of new diagnostic tests (high resolution MRI (Magnetic Resonance Imaging), colour duplex USS (Ultra Sound Scan) and PET (Positive Emission Topography) can we justify invasive surgery to all patients on histological grounds when the results may not alter management? Further investigation is needed directly comparing newer imaging modalities to histology.

Can the specificity of the FDT for glaucoma be improved by confirming abnormal results?

PURPOSE

To determine whether the specificity of the frequency-doubling technology (FDT) perimeter in the screening mode for glaucoma can be improved by repeating abnormal screening results.

METHODS

The FDT perimeter was used in C-20-5 screening mode, and the right eye was tested first. After both eyes were tested, the screening was repeated in eyes with any abnormal visual field defects on FDT perimetry. The printouts were categorized as possible visual field abnormality (zero or one miss), probable visual field abnormality (two to four misses), and definite visual field abnormality (more than five misses). A clinical ophthalmologic examination was conducted on the day of the FDT perimetry screening.

RESULTS

Complete data were available for 223 people. The participants ranged in age from 23 to 91 years (mean, 68.5 years; standard deviation. 13.7 years), and 119 (53%) were women. The sensitivity of the FDT perimetry screening was 100%; both cases of glaucoma showed an abnormality on FDT perimetry both times. The specificity improved moderately from the first screening to the second screening. The specificity the first time was 62% (95% confidence interval, 53.1-71.2). The specificity the second time was 68.5% (95% confidence interval, 59.8-77.1). Improvement on FDT perimetry rescreening varied by the language spoken at home. Seven of the 19 non-English speakers without glaucoma improved on rescreening, compared with none of the 23 English speakers (P = 0.002). Seven of the 25 right eyes with FDT perimetry abnormalities both times and no glaucoma had no other detectable diseases. Three of 24 left eyes with FDT perimetry abnormalities both times and no glaucoma had no other detectable diseases. Of the 85 patients who did not have glaucoma but had FDT perimetry abnormalities both times, only one did not have some other detectable disease.

DISCUSSION

In summary, the sensitivity for glaucoma of the C-20-5 screening mode is excellent, but a paradigm for screening with the FDT perimeter to improve the overall specificity for glaucoma still must be developed.

Analysis of myocilin mutations in 1703 glaucoma patients from five different populations

A glaucoma locus, GLC1A, was identified previously on chromosome 1q. A gene within this locus (encoding the protein myocilin) subsequently was shown to harbor mutations in 2-4% of primary open angle glaucoma patients. A total of 1703 patients was screened from five different populations representing three racial groups. There were 1284 patients from primarily Caucasian populations in Iowa (727), Australia (390) and Canada (167). A group of 312 African American patients was from New York City and 107 Asian patients from Japan. Overall, 61 different myocilin sequence variations were identified. Of the 61 variations, 21 were judged to be probable disease-causing mutations. The number of probands found to harbor such mutations in each population was: Iowa 31/727 (4.3%), African Americans from New York City 8/312 (2.6%), Japan 3/107 (2.8%), Canada 5/167 (3.0%), Australia 11/390 (2.8%) and overall 58/1703 (3. 4%). Overall, 16 (76%) of 21 mutations were found in only one population. The most common mutation observed, Gln368Stop, was found in 27/1703 (1.6%) glaucoma probands and was found at least once in all groups except the Japanese. Studies of genetic markers flanking the myocilin gene suggest that most cases of the Gln368Stop mutations are descended from a common founder. Although the specific mutations found in each of the five populations were different, the overall frequency of myocilin mutations was similar ( approximately 2-4%) in all populations, suggesting that the increased rate of glaucoma in African Americans is not due to a higher prevalence of myocilin mutations.

A clinical and cytological study of vitamin A deficiency in Kiribati

Vitamin A status was assessed clinically and by conjunctival impression cytology in a selected group under seven years of age in the Republic of Kiribati. A total of 230 children were studied. Of 185 with readable histology, 14.6% were clinically and histologically abnormal; 19.5% were clinically abnormal but histologically normal; and 15.7% were clinically normal and histologically abnormal. The remainder (50.3%) were clinically and histologically normal. There was a significant correlation between clinical disease and histology (P < 0.001). The prevalence of the disease in males was 45.8% and 26.3% in females. The risk of deficiency appeared to increase with advancing age. There was no significant difference between the two villages studied.
