The influence of anastomotic techniques on postoperative anastomotic complications: Results of the Oesophago-Gastric Anastomosis Audit. J Thorac Cardiovasc Surg 2022; 164:674-684.e5. [PMID: 35249756 DOI: 10.1016/j.jtcvs.2022.01.033] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/24/2021] [Revised: 12/22/2021] [Accepted: 01/18/2022] [Indexed: 12/08/2022]
Abstract
BACKGROUND The optimal anastomotic techniques in esophagectomy to minimize rates of anastomotic leakage and conduit necrosis are not known. The aim of this study was to assess whether the anastomotic technique was associated with anastomotic failure after esophagectomy in the international Oesophago-Gastric Anastomosis Audit cohort. METHODS This prospective observational multicenter cohort study included patients undergoing esophagectomy for esophageal cancer over 9 months during 2018. The primary exposure was the anastomotic technique, classified as handsewn, linear stapled, or circular stapled. The primary outcome was anastomotic failure, namely a composite of anastomotic leakage and conduit necrosis, as defined by the Esophageal Complications Consensus Group. Multivariable logistic regression modeling was used to identify the association between anastomotic techniques and anastomotic failure, after adjustment for confounders. RESULTS Of the 2238 esophagectomies, the anastomosis was handsewn in 27.1%, linear stapled in 21.0%, and circular stapled in 51.9%. Anastomotic techniques differed significantly by the anastomosis sites (P < .001), with the majority of neck anastomoses being handsewn (69.9%), whereas most chest anastomoses were stapled (66.3% circular stapled and 19.3% linear stapled). Rates of anastomotic failure differed significantly among the anastomotic techniques (P < .001), from 19.3% in handsewn anastomoses, to 14.0% in linear stapled anastomoses, and 12.1% in circular stapled anastomoses. This effect remained significant after adjustment for confounding factors on multivariable analysis, with an odds ratio of 0.63 (95% CI, 0.46-0.86; P = .004) for circular stapled versus handsewn anastomosis. However, subgroup analysis by anastomosis site suggested that this effect was predominantly present in neck anastomoses, with anastomotic failure rates of 23.2% versus 14.6% versus 5.9% for handsewn versus linear stapled anastomoses versus circular stapled neck anastomoses, compared with 13.7% versus 13.8% versus 12.2% for chest anastomoses. CONCLUSIONS Handsewn anastomoses appear to be independently associated with higher rates of anastomotic failure compared with stapled anastomoses. However, this effect seems to be largely confined to neck anastomoses, with minimal differences between techniques observed for chest anastomoses. Further research into standardization of anastomotic approach and techniques may further improve outcomes.

Abstract
Abstract
Background
Textbook outcome has been proposed as a tool for the assessment of oncological surgical care. However, an international assessment in patients undergoing oesophagectomy for oesophageal cancer has not been reported. This study aimed to assess textbook outcome in an international setting.
Methods
Patients undergoing curative resection for oesophageal cancer were identified from the international Oesophagogastric Anastomosis Audit (OGAA) from April 2018 to December 2018. Textbook outcome was defined as the percentage of patients who underwent a complete tumour resection with at least 15 lymph nodes in the resected specimen and an uneventful postoperative course, without hospital readmission. A multivariable binary logistic regression model was used to identify factors independently associated with textbook outcome, and results are presented as odds ratio (OR) and 95 per cent confidence intervals (95 per cent c.i.).
Results
Of 2159 patients with oesophageal cancer, 39.7 per cent achieved a textbook outcome. The outcome parameter ‘no major postoperative complication’ had the greatest negative impact on a textbook outcome for patients with oesophageal cancer, compared to other textbook outcome parameters. Multivariable analysis identified male gender and increasing Charlson comorbidity index with a significantly lower likelihood of textbook outcome. Presence of 24-hour on-call rota for oesophageal surgeons (OR 2.05, 95 per cent c.i. 1.30 to 3.22; P = 0.002) and radiology (OR 1.54, 95 per cent c.i. 1.05 to 2.24; P = 0.027), total minimally invasive oesophagectomies (OR 1.63, 95 per cent c.i. 1.27 to 2.08; P < 0.001), and chest anastomosis above azygous (OR 2.17, 95 per cent c.i. 1.58 to 2.98; P < 0.001) were independently associated with a significantly increased likelihood of textbook outcome.
Conclusion
Textbook outcome is achieved in less than 40 per cent of patients having oesophagectomy for cancer. Improvements in centralization, hospital resources, access to minimal access surgery, and adoption of newer techniques for improving lymph node yield could improve textbook outcome.

Postoperative outcomes in oesophagectomy with trainee involvement. BJS Open 2021; 5:zrab132. [PMID: 35038327 PMCID: PMC8763367 DOI: 10.1093/bjsopen/zrab132] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2021] [Accepted: 11/15/2021] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND The complexity of oesophageal surgery and the significant risk of morbidity necessitates that oesophagectomy is predominantly performed by a consultant surgeon, or a senior trainee under their supervision. The aim of this study was to determine the impact of trainee involvement in oesophagectomy on postoperative outcomes in an international multicentre setting. METHODS Data from the multicentre Oesophago-Gastric Anastomosis Study Group (OGAA) cohort study were analysed, which comprised prospectively collected data from patients undergoing oesophagectomy for oesophageal cancer between April 2018 and December 2018. Procedures were grouped by the level of trainee involvement, and univariable and multivariable analyses were performed to compare patient outcomes across groups. RESULTS Of 2232 oesophagectomies from 137 centres in 41 countries, trainees were involved in 29.1 per cent of them (n = 650), performing only the abdominal phase in 230, only the chest and/or neck phases in 130, and all phases in 315 procedures. For procedures with a chest anastomosis, those with trainee involvement had similar 90-day mortality, complication and reoperation rates to consultant-performed oesophagectomies (P = 0.451, P = 0.318, and P = 0.382, respectively), while anastomotic leak rates were significantly lower in the trainee groups (P = 0.030). Procedures with a neck anastomosis had equivalent complication, anastomotic leak, and reoperation rates (P = 0.150, P = 0.430, and P = 0.632, respectively) in trainee-involved versus consultant-performed oesophagectomies, with significantly lower 90-day mortality in the trainee groups (P = 0.005). CONCLUSION Trainee involvement was not found to be associated with significantly inferior postoperative outcomes for selected patients undergoing oesophagectomy. The results support continued supervised trainee involvement in oesophageal cancer surgery.

Mortality from esophagectomy for esophageal cancer across low, middle, and high-income countries: An international cohort study. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2021; 47:1481-1488. [PMID: 33451919 DOI: 10.1016/j.ejso.2020.12.006] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2020] [Accepted: 12/09/2020] [Indexed: 02/08/2023]
Abstract
BACKGROUND No evidence currently exists characterising global outcomes following major cancer surgery, including esophageal cancer. Therefore, this study aimed to characterise impact of high income countries (HIC) versus low and middle income countries (LMIC) on the outcomes following esophagectomy for esophageal cancer. METHOD This international multi-center prospective study across 137 hospitals in 41 countries included patients who underwent an esophagectomy for esophageal cancer, with 90-day follow-up. The main explanatory variable was country income, defined according to the World Bank Data classification. The primary outcome was 90-day postoperative mortality, and secondary outcomes were composite leaks (anastomotic leak or conduit necrosis) and major complications (Clavien-Dindo Grade III - V). Multivariable generalized estimating equation models were used to produce adjusted odds ratios (ORs) and 95% confidence intervals (CI95%). RESULTS Between April 2018 to December 2018, 2247 patients were included. Patients from HIC were more significantly older, with higher ASA grade, and more advanced tumors. Patients from LMIC had almost three-fold increase in 90-day mortality, compared to HIC (9.4% vs 3.7%, p < 0.001). On adjusted analysis, LMIC were independently associated with higher 90-day mortality (OR: 2.31, CI95%: 1.17-4.55, p = 0.015). However, LMIC were not independently associated with higher rates of anastomotic leaks (OR: 1.06, CI95%: 0.57-1.99, p = 0.9) or major complications (OR: 0.85, CI95%: 0.54-1.32, p = 0.5), compared to HIC. CONCLUSION Resections in LMIC were independently associated with higher 90-day postoperative mortality, likely reflecting a failure to rescue of these patients following esophagectomy, despite similar composite anastomotic leaks and major complication rates to HIC. These findings warrant further research, to identify potential issues and solutions to improve global outcomes following esophagectomy for cancer.

Disruption and bactericidal indices depicted in polygonal graphs to show multiple outcome effects of root canal irrigant supplements on single- and dual-species biofilms. Clin Oral Investig 2020; 24:3255-3264. [PMID: 31953683 DOI: 10.1007/s00784-020-03202-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2019] [Accepted: 01/07/2020] [Indexed: 11/30/2022]
Abstract
OBJECTIVES The aims of this study were to (1) investigate the relative time-dependent disruption and bactericidal effects of detergent-type surfactants on single- or dual-species biofilms of root canal isolates and (2) to examine the utility of polygonal graphs for depiction of biofilm disruption and cell killing. MATERIALS AND METHODS Single-species biofilms of Streptococcus sanguinis, Enterococcus faecalis, Fusobacterium nucleatum and Porphyromonas gingivalis were grown on nitro-cellulose membranes for 72 h and immersed in Tween®80, cetyltrimethylammoniumbromide (CTAB), and sodium dodecyl sulphate (SDS) for 1-, 5- or 10-min (n = 3 per test). The number of viable and non-viable bacteria "disrupted" from the biofilm and those "remaining-attached" was determined using a viability stain in conjunction with fluorescence microscopy. The data were analysed using non-parametric Kruskal-Wallis test with 5% significance level. RESULTS Gram-negative obligate anaerobes were more susceptible to cell removal than gram-positive facultative anaerobes. The majority of cells were disrupted after 1-min of exposure; however, the extent varied according to the agent and species. CTAB and SDS were more effective than Tween 80™ at disrupting biofilms and killing cells but all agents failed to achieve 100% disruption/kill. CONCLUSIONS Biofilm disruption and cell viability were influenced by the species, the test agent and the duration of exposure. CTAB and SDS were more effective in biofilm disruption than Tween 80™. Graphical depiction of biofilm disruption- and viability-outcomes provides an alternative means of simultaneously visualising and analysing relative efficacy in different domains. CLINICAL RELEVANCE Surfactants were not as effective at biofilm disruption as NaOCl but may be added to other non-disruptive antibacterial agents to enhance this property.

Abstract
BACKGROUND The prediction of long-term survival after surgery is complex. Natriuretic peptides can predict short-term postoperative cardiac morbidity and mortality. This study aims to determine the long-term prognostic significance of preoperative B-type natriuretic peptide (BNP) concentration after major non-cardiac surgery. METHODS We conducted a prospective single-centre observational cohort study in a West of Scotland teaching hospital. Three hundred and forty-five patients undergoing major non-cardiac surgery were included. The primary endpoint was long-term all-cause mortality. RESULTS Overall survival was 67.8% (234/345), with 27 postoperative deaths (within 42 days) and 84 deaths at subsequent follow-up (median follow-up 953 days). A BNP concentration of >87.5 pg ml(-1) best predicted mortality, and the mean survival of patients with an elevated BNP (>87.5 pg ml(-1)) was 731.9 (95% CI 613.6-850.2) days compared with 1284.6 days [(95% CI 1219.3-1350.0), P<0.001] in patients with a BNP<87.5 pg ml(-1). BNP was an independent predictor of survival. CONCLUSIONS BNP is an independent predictor of long-term survival after major non-cardiac surgery. A simple preoperative blood test can provide predictive information on future risk of death, and potentially has a role in preoperative risk assessment.

Abstract
BACKGROUND Isotretinoin is very frequently the drug of choice for the management of severe recalcitrant nodular acne. Recently, a new micronized and more bioavailable formulation of isotretinoin has been developed that permits once-daily administration in lower doses than usually used with standard isotretinoin (Accutane), regardless of whether it is taken with or without food. OBJECTIVE Our purpose was to determine whether micronized isotretinoin and standard isotretinoin are clinically equivalent. METHODS In this multicenter, double-blind, double-dummy study, 600 patients with severe recalcitrant nodular acne were treated with either 0.4 mg/kg of micronized isotretinoin once daily without food (n = 300) or 1.0 mg/kg per day of standard isotretinoin in two divided doses with food (n = 300). Lesion counts were monitored over 20 weeks. RESULTS Both treatment groups in this well-controlled clinical trial experienced an equivalent reduction in the number of total nodules (facial plus truncal). In addition, an equivalent proportion of patients achieved 90% clearance of the total number of nodules. Both formulations had similar results for other efficacy variables. CONCLUSION Once-daily use of the micronized and more bioavailable formulation of isotretinoin under fasted conditions is clinically equivalent to the standard twice-daily formulation under fed conditions in the treatment of severe recalcitrant nodular acne.

Abstract
BACKGROUND Isotretinoin is a very effective drug for treating severe recalcitrant nodular acne. A new micronized formulation of isotretinoin has been shown to be clinically equivalent to standard isotretinoin with improved bioavailability and minimal food effect. The safety profile of the micronized formulation has not been described previously. OBJECTIVE The objective of this article is to report the incidence and intensity of adverse events found in a comparative, double-blind efficacy study that showed clinical equivalence of the new micronized formulation of isotretinoin and the standard isotretinoin formulation (Accutane). METHODS Six hundred patients with severe recalcitrant nodular acne were treated with micronized isotretinoin (n = 300) under fasted conditions or standard isotretinoin (n = 300) under fed conditions. One cohort received single daily doses of 0.4 mg/kg of micronized isotretinoin without food and the other cohort received 1.0 mg/kg per day of standard isotretinoin in two divided doses with food. Adverse events were monitored during 20 weeks of drug therapy. RESULTS The proportion of adverse events in most body systems was generally lower in patients receiving micronized isotretinoin than in those receiving standard isotretinoin. CONCLUSION Micronized isotretinoin appears to have a safety profile similar to that of standard isotretinoin and to carry a lower risk of mucocutaneous events and hypertriglyceridemia.

Abstract
OBJECTIVE The goal of this study was to analyze temporal bone necrosis and classify its diagnosis and treatment according to extent of necrosis and cause. METHODS AND MATERIAL Twenty-six cases of temporal bone necrosis were retrospectively reviewed between 1988 and 1997 at the University of British Columbia. RESULTS Patients were classified on the basis of disease extent restricted to the tympanic bone or extension beyond the tympanic bone, as well as on the basis of the cause of disease; treatment based on classification. Patients with localized disease of the tympanic bone had minimal symptoms. Those with radiation-induced localized necrosis were less likely to respond to conservative medical management. Patients with diffuse disease were more likely to require surgical intervention. CONCLUSIONS Temporal bone necrosis comprises a spectrum of disease from idiopathic tympanic bone necrosis, which rarely requires surgery, to the more severe forms of radiation-induced diffuse temporal bone necrosis that may cause life-threatening complications requiring surgical intervention.

Abstract
OBJECTIVE To investigate issues influencing the role of general practitioners in managing child and adolescent mental health problems. DESIGN A postal questionnaire survey inviting respondents to rate statements about managing child and adolescent mental health issues. SETTING Population of urban Scottish general practitioners. SUBJECTS General practitioner principals. RESULTS Of the 56% who responded, 31.3% reported that child and adolescent mental health services (CAMHS) were easy to access. Only a minority agreed that users' concerns prevented them from referring to CAMHS, and that these were more likely with young people or parents than with children. The number of respondents who considered their knowledge base, experience or training in this area to be adequate was particularly low. CONCLUSION There may be a significant mismatch between what is expected of general practitioners in relation to child and adolescent mental health problems and what general practitioners themselves feel they are equipped to deliver.

Abstract
A set of 16 treatment goals, related to 4 areas of adolescent functioning, were defined and employed in the initial and discharge assessments of 276 patients, admitted to 4 inpatient units, examined during a multi-centre prospective study of adolescent psychiatric hospitalizations. At discharge, subjects showed a substantial improvement across all treatment goals; least improvement was observed amongst those goals most frequently targeted. The clinical investigators consider the treatment goal definitions used in this study a meaningful way of measuring psychiatric disturbances in adolescence as well as a useful measure of change in an inpatient population. Further development of the treatment goal definitions would produce a robust clinical and audit tool.

Abstract
Sixteen Axis 5 ICD-10 codes were applied to a prospective multicentre study of 276 adolescent psychiatric inpatients. Frequency distributions were obtained for the whole cohort and separately for each of the seven main ICD-9 psychiatric diagnoses. Certain abnormal psychosocial situations were associated with particular diagnoses, and many significant correlations were found between Axis 5 codes. Factor analysis with varimax rotation produced four factors accounting for 46% of the total variance.

Abstract
Through daily contact with injured people there was a feeling that most people are sufficiently aware of the dangers in specific risk factor activities, but were not fully aware that they could do a lot to prevent harm coming upon themselves. This paper describes the results of a self-administered questionnaire about the accidents people suffered at home, their level of awareness of the risk they were undertaking, whether they had had a similar accident before, what they think the recovery period from their injury is likely to be and knowledge of, and accidents involving, 17 generally known risk activities. The results confirm that most people are indeed aware of dangers yet a large number still have accidents in spite of that. The results also indicate that campaigns advising people how to avoid these dangers could be successful.

Abstract
Invasive external otitis occurs almost exclusively in patients with longstanding diabetes. Except for occasional cases, the etiologic agent has been Pseudomonas aeruginosa. We report a case caused by Aspergillus species in a diabetic patient with acute leukemia. Persistent infection was documented by culture and histology after a course of intravenous amphotericin B (total dose, 2 g). Clinical resolution occurred in association with a 3-month course of oral itraconazole. Four previously reported cases of invasive aspergillus otitis are reviewed.

Abstract
This paper describes the use of family therapy with adolescent school refusers. School refusal is assessed and formulated from a family systems perspective, and therapy proceeds with the crisis precipitated by insisting on the adolescent's early return to school. Some of the common problems encountered in this approach are considered along with its results.

Abstract
The objective of this study was to determine the effect of age on the blood levels of 1,25-dihydroxyvitamin D (1,25(OH)2D) and immunoreactive parathyroid hormone (iPTH) in normal, healthy males and females. A total of 855 normal subjects (361 males and 494 females) were studied. The results show that for healthy males, blood concentrations of 1,25(OH)2D remained essentially constant with increasing age up to age 65, and then the concentrations decreased significantly. For healthy females, 1,25(OH)2D increased up to age 65, and then decreased at a significant rate. Serum iPTH in males increased with advancing age, but the rate of increase was greater after age 65. In females a significant increase in iPTH concentrations did not occur until after age 65. Serum creatinine increased in both males and females with advancing age.

Abstract
Serum bone Gla protein (BGP) was measured by radioimmunoassay in 166 healthy men and women aged 30-90 years. Serum BGP levels increased with age in both sexes and were higher in women than in men at all ages. The most striking rise occurred in women after age 40-49. BGP was significantly correlated positively with serum alkaline phosphatase and negatively with midshaft and distal bone mass in both sexes. In women only, BGP levels were significantly positively related to levels of immunoreactive parathyroid hormone (iPTH). When age was included in the multiple regression analysis BGP was still correlated with alkaline phosphatase in both sexes and iPTH in women only. Serum BGP levels were significantly higher in 13 osteoporotic patients than in age-matched controls. It is postulated that with increasing age 1,25-dihydroxyvitamin D levels fall, causing a rise in iPTH and thus in bone turnover, which is reflected by a rise in BGP levels.

Abstract
To assess the relationship between the decreased bone mass observed in young insulin-requiring diabetic patients and vitamin D metabolism, we measured serum 25-hydroxyvitamin D, 24,25-dihydroxyvitamin D, and 1,25-dihydroxyvitamin D concentration in 45 white, insulin-dependent diabetic subjects, 7-18 yr of age. Metacarpal cortical thickness in 87% of these diabetics was below the mean for their respective ages, while 16% had a cortical thickness value greater than 2 sDs below the mean. Serum calcium and phosphate concentrations were normal, immunoreactive parathyroid hormone was in the low normal range, and total serum alkaline phosphatase was elevated compared to age- and sex-matched controls. Circulating 24,25-dihydroxyvitamin D concentrations were significantly elevated, and 1,25-dihydroxyvitamin D was significantly decreased. The increase in 24,25-dihydroxyvitamin D was greater in the diabetics with the most severe bone loss and was maximally increased during the first 5 yr of clinical diabetes. No apparent correlation was seen between metabolic control, as measured by hemoglobin A1C and urine and plasma glucose, and the circulating levels of the vitamin D metabolites. Despite appropriate insulin replacement, alterations in vitamin D metabolism occur in the young insulin-dependent diabetic and could relate to the decrease in cortical bone mass observed in these patients.
