Perioperative management of sarcopenia in patients undergoing major surgeries in Singapore: a modified delphi consensus. Int J Surg 2024:01279778-990000000-01419. [PMID: 38701514 DOI: 10.1097/js9.0000000000001515] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2024] [Accepted: 04/14/2024] [Indexed: 05/05/2024]
Abstract
BACKGROUND Ageing population is a worldwide phenomenon with correspondingly higher proportion of older patients being treated in the hospital setting. Sarcopenia, which increases with age, has serious negative implications on health, hospitalization and overall postoperative recovery. There is no mutual consensus on perioperative management of sarcopenia in surgical patients in Singapore. The purpose of this study is to create greater clarity pertaining to the recognition of sarcopenia, the application of assessment criteria of sarcopenia and perioperative management of surgical patients in Singapore. METHODS A modified Delphi consensus consisting of a panel of experts from Singapore forming a multidisciplinary team, including surgeons, geriatricians, anesthesiologists, physiotherapists and dieticians. Eight recommendations were proposed by the steering committee. Literature search from MEDLINE, Embase and Scopus for articles up till June 2023 were performed to support recommendation statements. The expert panel voted on agreement to recommendation statements and graded the level of evidence supporting each statement through surveys to achieve consensus, set at 85% a priori. RESULTS The panelists underwent two rounds of anonymized, independent voting before reaching consensus for all eight statements. After the first round, seven statements reached consensus, including the corresponding grading for level of evidence. The statement which did not achieve consensus was revised with supporting literature and after the second round of survey, all eight statements and level of evidence reached consensus, completing the Delphi process. These eight statements covered themes to (1) encourage the identification of sarcopenia, (2) guide pre-operative and (3) post-operative management of sarcopenia. CONCLUSION With the varying approaches in perioperative management, poor understanding of and identification of sarcopenia can result in suboptimal management of sarcopenia in surgical patients. Given the abundance of evidence linking beneficial impact on recovery and post-operative complications with prudent management of sarcopenia, it is imperative and urgent to achieve awareness and consensus.

Multimodal prerehabilitation for elderly patients with sarcopenia in colorectal surgery. Ann Coloproctol 2024; 40:3-12. [PMID: 37004990 PMCID: PMC10915526 DOI: 10.3393/ac.2022.01207.0172] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/27/2022] [Revised: 01/14/2023] [Accepted: 01/16/2023] [Indexed: 04/04/2023] Open
Abstract
Sarcopenia, which is characterized by progressive and generalized loss of skeletal muscle mass and strength, has been well described to be associated with numerous poor postoperative outcomes, such as increased perioperative mortality, postoperative sepsis, prolonged length of stay, increased cost of care, decreased functional outcome, and poorer oncological outcomes in cancer surgery. Multimodal prehabilitation, as a concept that involves boosting and optimizing the preoperative condition of a patient prior to the upcoming stressors of a surgical procedure, has the purported benefits of reversing the effects of sarcopenia, shortening hospitalization, improving the rate of return to bowel activity, reducing the costs of hospitalization, and improving quality of life. This review aims to present the current literature surrounding the concept of sarcopenia, its implications pertaining to colorectal cancer and surgery, a summary of studied multimodal prehabilitation interventions, and potential future advances in the management of sarcopenia.

Abstract
OBJECTIVES This case series would like to highlight hypophosphatemia related to ferric carboxymaltose and its adverse clinical consequences. BACKGROUND Intravenous iron supplementation is a good alternative to oral iron replacement in iron deficiency anaemia due to its ability to correct iron deficit with minimal infusions without incurring the gastrointestinal side effects of oral iron replacement. Ferric carboxymaltose is one common formula for intravenous iron supplementation. However, an increasingly recognised adverse side-effect of intravenous ferric carboxymaltose is hypophosphatemia. There has been increasing reports and studies highlighting hypophosphatemia related to intra-venous iron therapy. Though initially thought to be transient and asymptomatic, recent studies have shown that persistent hypophosphatemia in iron therapy can result in debilitating disease including myopathy, fractures and osteomalacia. METHODS A retrospective analysis of all patients who had ferric carboxymaltose was performed. RESULTS We highlight 3 cases where hyposphatemia affected the clinical outcomes. CONCLUSION With the increased use of IV iron it is important to be aware of the high potential for hypophosphatemia secondary to ferric carboxymaltose.

The imitation game: a review of the use of artificial intelligence in colonoscopy, and endoscopists' perceptions thereof. Ann Coloproctol 2023; 39:385-394. [PMID: 36907170 PMCID: PMC10626328 DOI: 10.3393/ac.2022.00878.0125] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/30/2022] [Revised: 12/22/2022] [Accepted: 01/09/2023] [Indexed: 03/14/2023] Open
Abstract
The development of deep learning systems in artificial intelligence (AI) has enabled advances in endoscopy, and AI-aided colonoscopy has recently been ushered into clinical practice as a clinical decision-support tool. This has enabled real-time AI-aided detection of polyps with a higher sensitivity than the average endoscopist, and evidence to support its use has been promising thus far. This review article provides a summary of currently published data relating to AI-aided colonoscopy, discusses current clinical applications, and introduces ongoing research directions. We also explore endoscopists' perceptions and attitudes toward the use of this technology, and discuss factors influencing its uptake in clinical practice.

Knowledge, perceptions and behaviours of endoscopists towards the use of artificial intelligence-aided colonoscopy. Surg Endosc 2023; 37:7395-7400. [PMID: 37670191 DOI: 10.1007/s00464-023-10412-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2022] [Accepted: 08/14/2023] [Indexed: 09/07/2023]
Abstract
BACKGROUND Recent developments in artificial intelligence (AI) systems have enabled advancements in endoscopy. Deep learning systems, using convolutional neural networks, have allowed for real-time AI-aided detection of polyps with higher sensitivity than the average endoscopist. However, not all endoscopists welcome the advent of AI systems. METHODS We conducted a survey on the knowledge of AI, perceptions of AI in medicine, and behaviours regarding use of AI-aided colonoscopy, in a single centre 2 months after the implementation of Medtronic's GI Genius in colonoscopy. We obtained a response rate of 66.7% (16/24) amongst consultant-grade endoscopists. Fisher's exact test was used to calculate the significance of correlations. RESULTS Knowledge of AI varied widely amongst endoscopists. Most endoscopists were optimistic about AI's capabilities in performing objective administrative and clinical tasks, but reserved about AI providing personalised, empathetic care. 68.8% (n = 11) of endoscopists agreed or strongly agreed that GI Genius should be used as an adjunct in colonoscopy. In analysing the 31.3% (n = 5) of endoscopists who disagreed or were ambivalent about its use, there was no significant correlation with their knowledge or perceptions of AI, but a significant number did not enjoy using the programme (p-value = 0.0128) and did not think it improved the quality of colonoscopy (p-value = 0.033). CONCLUSIONS Acceptance of AI-aided colonoscopy systems is more related to the endoscopist's experience with using the programme, rather than general knowledge or perceptions towards AI. Uptake of such systems will rely greatly on how the device is delivered to the end user.

Pre-operative erector spinae plane block should be considered a viable option for laparoscopic colectomies. Surg Endosc 2023; 37:7128-7135. [PMID: 37322360 DOI: 10.1007/s00464-023-10171-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2023] [Accepted: 05/08/2023] [Indexed: 06/17/2023]
Abstract
BACKGROUND The Erector Spinae Plane (ESP) block is a recent development in the field of regional anaesthesia and has been increasingly explored for abdominal surgeries to reduce opioid use and improve pain control. Colorectal cancer is the commonest cancer in multi-ethnic Singapore and requires surgery for curative treatment. ESP is a promising alternative in colorectal surgeries, but few studies have evaluated its efficacy in such surgeries. Therefore, this study aims to evaluate the use of ESP blocks in laparoscopic colorectal surgeries to establish its safety and efficacy in this field. METHODS A prospective two-armed interventional cohort study comparing T8-T10 ESP blocks with conventional multimodal intravenous analgesia for laparoscopic colectomies was conducted in a single institution in Singapore. The decision for doing an ESP block versus conventional multimodal intravenous analgesia was made by a consensus between the attending surgeon and anesthesiologist. Outcomes measured were total intra-operative opioid consumption, post-operative pain control and patient outcome. Post-operative pain control was measured by pain score, analgesia use, and amount of opioids consumed. Patient outcome was determined by presence of ileus. RESULTS A total of 146 patients were included, of which 30 patients received an ESP block. Overall, the ESP group had a significantly lower median opioid usage both intra-operatively and post-operatively (p = 0.031). Fewer patients required patient-controlled analgesia and rescue analgesia post-operatively for pain control (p < 0.001) amongst the ESP group. Pain scores were similar and post-operative ileus was absent in both groups. Multivariate analysis found that the ESP block had an independent effect on reducing intra-opioid consumption (p = 0.014). Multivariate analysis of post-operative opioid use and pain scores did not yield statistically significant results. CONCLUSIONS The ESP block was an effective alternative regional anaesthesia for colorectal surgery that reduced intra-operative and post-operative opioid use while attaining satisfactory pain control.

Incidence and predictors of hypophosphataemia after ferric carboxymaltose use-A 3-year experience from a single institution in Singapore. Br J Haematol 2023; 202:1199-1204. [PMID: 37455143 DOI: 10.1111/bjh.18979] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2023] [Revised: 06/26/2023] [Accepted: 07/04/2023] [Indexed: 07/18/2023]
Abstract
Ferric carboxymaltose (FCM) administration helps reduce transfusion requirements in the perioperative situation, which improves patient outcomes and reduces healthcare costs. However, there is increasing evidence of hypophosphataemia after FCM use. We aim to determine the incidence of hypophosphataemia after FCM administration and elucidate potential biochemical factors associated with the development of subsequent hypophosphataemia. A retrospective review of anonymised data of all FCM administrations in a single institution was conducted from August 2018 to August 2021. Each unique FCM dose administered was examined to assess its effect on Hb and serum phosphate levels within the subsequent 28 days from each FCM administration. Phosphate levels were repeatedly measured within the 28-day interval and the lowest phosphate level within that period was determined. Patients' serum phosphate levels within 28 days of FCM administration were compared against normal serum phosphate levels within 2 weeks before FCM administration. The odds ratios of various pre-FCM serum markers were calculated to elucidate potential biochemical predictors of post-FCM hypophosphataemia. In 3 years, a total of 1296 doses of FCM were administered to 1069 patients. The mean improvement in Hb was 2.45 g/dL (SD = 1.94) within 28 days of FCM administration, with the mean time taken to peak Hb levels being 6.3 days (SD = 8.63), which is earlier than expected, but was observed in this study and hence reported. The incidence of hypophosphataemia <0.8 mmol/L was 22.7% (n = 186), and <0.4 mmol/L was 1.6% (n = 9). This figure is lower than the numbers reported in previously published meta-analyses given that routine checks of serum phosphate levels were not conducted initially and hence could possibly be higher. The odds of developing hypophosphataemia (<0.8 mmol/L) were 27.7 (CI: 17.3-44.2, p < 0.0001) if baseline serum phosphate was less than 1 mmol/L. The odds of developing hypophosphataemia (<0.8 mmol/L) were 1.3 (CI: 1.08-1.59, p < 0.01) if the change in Hb levels observed after FCM administration were more than 4 g/dL. Hypophosphataemia after FCM administration is significant and FCM should be used by clinicians with caution.

One-year review of real-time artificial intelligence (AI)-aided endoscopy performance. Surg Endosc 2023:10.1007/s00464-023-09979-8.

Abstract
BACKGROUND Colonoscopies have long been the gold standard for detection of pre-malignant neoplastic lesions of the colon. Our previous study tried real-time artificial intelligence (AI)-aided colonoscopy over a three-month period and found significant improvements in collective and individual endoscopist's adenoma detection rates compared to baseline. As an expansion, this study evaluates the 1-year performance of AI-aided colonoscopy in the same institution. METHODS A prospective cohort study was conducted in a single institution in Singapore. The AI software used was GI Genius™ Intelligent Endoscopy Module, US-DG-2000309 © 2021 Medtronic. Between July 2021 and June 2022, polypectomy rates in non-AI-aided colonoscopies and AI-aided colonoscopies were calculated and compared. Some of the AI-aided colonoscopies were recorded and video reviewed. A "hit" was defined as a sustained detection of an area by the AI. If a polypectomy was performed for a "hit," its histology was reviewed. Additional calculations for polyp detection rate (PDR), adenoma detection rate (ADR), and adenoma detection per colonoscopy (ADPC) were performed. Cost analysis was performed to determine cost effectiveness of subscription to the AI program. RESULTS 2433 AI-aided colonoscopies were performed between July 2021 and June 2022 and compared against 1770 non-AI-aided colonoscopies. AI-aided colonoscopies yielded significantly higher rates of polypectomies (33.6%) as compared with non-AI-aided colonoscopies (28.4%) (p < 0.001). Among the AI-aided colonoscopies, 1050 were reviewed and a final 843 were included for additional analysis. The polypectomy to "hit" ratio was 57.4%, PDR = 45.6%, ADR = 32.4%, and ADPC = 2.08. Histological review showed that 25 polyps (3.13%) were sessile-serrated adenomas. Cost analysis found that the increased polypectomy rates in AI-aided colonoscopes led to an increase in revenue, which covered the subscription cost with an excess of USD 20,000. CONCLUSION AI-aided colonoscopy is a cost effective means of improving colonoscopy quality and may help advance colorectal cancer screening in Singapore.

Abstract
BACKGROUND Colonoscopy is a mainstay to detect premalignant neoplastic lesions in the colon. Real-time Artificial Intelligence (AI)-aided colonoscopy purportedly improves the polyp detection rate, especially for small flat lesions. The aim of this study is to evaluate the performance of real-time AI-aided colonoscopy in the detection of colonic polyps. METHODS A prospective single institution cohort study was conducted in Singapore. All real-time AI-aided colonoscopies, regardless of indication, performed by specialist-grade endoscopists were anonymously recorded from July to September 2021 and reviewed by 2 independent authors (FHK, JL). Sustained detection of an area by the program was regarded as a "hit". Histology for the polypectomies were reviewed to determine adenoma detection rate (ADR). Individual endoscopist's performance with AI were compared against their baseline performance without AI endoscopy. RESULTS A total of 24 (82.8%) endoscopists participated with 18 (62.1%) performing ≥ 5 AI-aided colonoscopies. Of the 18, 72.2% (n = 13) were general surgeons. During that 3-months period, 487 "hits" encountered in 298 colonoscopies. Polypectomies were performed for 51.3% and 68.4% of these polypectomies were adenomas on histology. The post-intervention median ADR was 30.4% was higher than the median baseline polypectomy rate of 24.3% (p = 0.02). Of the adenomas excised, 14 (5.6%) were sessile serrated adenomas. Of those who performed ≥ 5 AI-aided colonoscopies, 13 (72.2%) had an improvement of ADR compared to their polypectomy rate before the introduction of AI, of which 2 of them had significant improvement. CONCLUSIONS Real-time AI-aided colonoscopy have the potential to improved ADR even for experienced endoscopists and would therefore, improve the quality of colonoscopy.

Colorectal cancer patients advocating screening to their siblings: a randomized behavioral intervention. Gastrointest Endosc 2022; 95:519-526.e2.

Abstract
BACKGROUND AND AIMS Siblings of colorectal cancer (CRC) patients are at increased risk of developing CRC, but screening rates remain low. Through a randomized behavioral intervention, this study aimed to determine whether patients can advocate screening to their siblings using a tailored educational package. METHODS CRC survivors were recruited and randomized into relaying either tailored materials (intervention group) or existing national screening guidelines (control group) to their siblings. Siblings could respond to the study team if they were interested in learning about CRC screening. Study outcomes were patient advocacy rates (number of patients who had successfully contacted at least 1 eligible sibling) between groups and the proportion of eligible siblings who responded. RESULTS Between May 2017 and March 2021, 219 CRC patients were randomized to the intervention (n = 110) and control (n = 109) groups. Patient advocacy rates were high and did not differ significantly between groups. However, only 14.3% of eligible siblings (n = 85) responded to the study team. Siblings of patients from the intervention group were more likely to respond (adjusted odds ratio, 1.8; 95% confidence interval, 1.1-3.0; P < .05). Moreover, after controlling for potential confounders, siblings aged ≥60 years were significantly less likely to respond (adjusted odds ratio, .3; 95% confidence interval, .1-.7; P < .01). CONCLUSIONS CRC patients are willing advocates of screening, and siblings contacted by patients from the intervention group were also more likely to reach out to the study team. However, overall sibling response rates were low despite advocacy, suggesting that patient-led advocacy should at best be used as an adjunct to other, multipronged CRC screening promotion modalities.

Abstract
PURPOSE The COVID-19 pandemic and resultant lockdown measures potentially delay management of non-communicable, life-limiting diseases like colorectal cancer (CRC) through avoidance of healthcare facilities by the public and diversion of resources within healthcare systems. This study aims to evaluate the impact of Singapore's "Circuit Breaker (CB)" lockdown measures on CRC disease presentation and short-term surgical outcomes, while comparing Singapore's approach against other countries which employed similar lockdown measures. METHODS Patients whose initial diagnosis of CRC was made within the 6-month pre-CB (6/10/19-6/4/20) ("pre-CB group") and post-CB (7/4/20-7/10/20) ("post-CB group") period were enrolled retrospectively. The groups were compared based on severity of disease on presentation and short-term operative outcomes. RESULTS In total, 105 patients diagnosed with CRC were enrolled in this study. When comparing pre-CB and post-CB groups, there was no significant difference in stage of CRC on presentation (p = 0.850). There was also no increase in need for emergent operations (p = 0.367). For patients who had undergone an operation, postoperative morbidity was not significantly higher in the post-CB group (p = 0.201). Both groups of patients had similar length of stay in the hospital (p = 0.438). CONCLUSION Unlike similar high-income countries, Singapore did not see later stage disease on presentation and poorer operative outcomes after lockdown measures. Possible reasons include lesser healthcare avoidance behaviours amongst Singaporeans, and adequate preparation of resources and contingency plans formed by hospitals after previous pandemics.

Abstract
Background With increasing global life expectancy, the number of major surgeries performed on aged adults invariably increases. This study aimed to examine the effectiveness of a structured prehabilitative program for aged colorectal cancer patients in improving short‐term surgical outcomes. Methods A prospective philanthropically sponsored Programme for Enhanced Elderly Recovery at Sengkang General Hospital (PEERS) was initiated in February 2017 for patients ≥70‐years‐old who were due to undergo elective colectomies. These patients were put through a 2‐ to 4‐week‐long program before surgery, which included geriatric assessment, nutrition supplementation, and resistance training. They were compared with patients from a similar age group before PEERS was introduced (non‐PEERS). Results Fifty‐eight patients, with a median age of 78.5 (70–93) years, were recruited from a single institution to undergo PEERS. Baseline characteristics between the groups were similar. There was no significant improvement of anthropometric and functional characteristics before and after PEERS. Duration of hospitalization was shorter in the PEERS group (9 vs 11 days, P = 0.01). Both groups had similar 30‐days’ morbidity rates (8.6% vs 17.4%, P = 0.26). The PEERS group had significant improvement in their median EuroQol‐5 Dimension score (0.70 presurgery to 0.80 6‐months’ postsurgery, P = 0.01). After multivariate analysis, the average duration of hospitalization in the PEERS group was 6.8 days shorter (P = 0.018; CI, 1.2–12.4) after adjusting for modality of surgery and complications. This represented a cost saving of USD$11,838.80. Conclusion A standardized prehabilitation program for aged adults reduced the duration of hospitalization, improved the quality of life after surgery, and reduced costs.

Abstract
A growing body of evidence has demonstrated the prognostic significance of sarcopenia in surgical patients as an independent predictor of postoperative complications and outcomes. These included an increased risk of total complications, major complications, re-admissions, infections, severe infections, 30 d mortality, longer hospital stay and increased hospitalization expenditures. A program to enhance recovery after surgery was meant to address these complications; however, compliance to the program since its introduction has been less than ideal. Over the last decade, the concept of prehabilitation, or “pre-surgery rehabilitation”, has been discussed. The presurgical period represents a window of opportunity to boost and optimize the health of an individual, providing a compensatory “buffer” for the imminent reduction in physiological reserve post-surgery. Initial results have been promising. We review the literature to critically review the utility of prehabilitation, not just in the clinical realm, but also in the scientific realm, with a resource management point-of-view.

Abstract
Abstract
Introduction
Post-operative recurrence after Crohn’s surgery poses a significant challenge to clinicians with an estimated of 70-90% recurrence rate. However, with the advent of biologics, reduction of recurrence after surgery has been observed in various landmark trials. Hence, we aim to quantify the rate of recurrence with post-operative biologics.
Method
Searches were done on Embase and Medline database for articles using biologics for post-operative management. A single arm meta-analysis with generalized linear mixed model and Clopper-Pearson method confidence interval was applied in the synthesis of the data on six months, one year, two year and five year.
Results
A total of 1,864 abstracts were identified, with a final total of 24 articles and 1042 patients were included in the meta-analysis. The one-year rate of recurrence for surgical, endoscopic and clinical was 3.08% (CI: 0.74% - 11.95%), 19.93% (15.81% - 24.81%) and 13.06% (CI: 8.18% - 18.92%) respectively. Correspondingly, the five-year recurrence 16.90% (CI: 9.57% - 28.11%), 84.21% (CI: 72.35% - 91.57%), 5.60% (CI: 9.92% -23.66%) respectively.
Conclusions
An observed reduction in surgical rates was reduced at five years with post-operative Crohn’s disease with biologics. Biologics therapy thus can be considered as a suitable alternative for reducing post-operative recurrence in individuals with higher risk.

Abstract
Gastrointestinal stromal tumour (GIST are the most common mesenchymal tumours; however, rectal GISTs account for <5%. In the pelvis they represent a diagnostic challenge with giant GISTs likely to be malignant. They may present with urological, gynaecological or rectal symptoms. Sphincter-preserving surgery can be aided by neoadjuvant therapy. We present an uncommon case of giant rectal GIST masquerading as acute urinary retention.

Abstract
OBJECTIVES The United Kingdom abdominal aortic aneurysm (AAA) screening programme refers aneurysms with ultrasound (US) diameters of ≥5.5 cm to vascular services for consideration of computed tomography (CT) and intervention. We investigated the discrepancy between US and CT, implications on clinical decisions and question at which stage CT be used. DESIGN/METHODS AAA USs over 5 years were retrospectively analysed. Patients included had aneurysms measuring ≥5 cm on US with subsequent CT within 2 months (n = 123). Based on maximum US diameters, 44 patients had aneurysms between 5 and 5.4 cm (group I) and 79 patients ≥5.5 cm (group II). Results were cross-referenced. Correlation and limits of agreement were calculated. Two radiologists re-measured 44 pairs of CT/US scans and the inter-observer bias in determining discrepancies between imaging modalities calculated. RESULTS Mean difference between imaging modalities was 0.21 cm (±0.39 cm, p < 0.001). Limits of agreement were -0.55 to 0.96 cm, exceeding clinical acceptability. Mean difference was higher and significant in group I (0.39 cm, p < 0.001) compared to group II (0.10 cm, p > 0.05). Seventy-percent of group I patients had CT scans revealing diameters of ≥5.5 cm. Inter-observer bias was not significant. CONCLUSION Significant differences between imaging modalities, more in US diameters of below 5.5 cm, exist. We recommend AAAs measuring ≥5 cm on US should undergo earlier referral to a vascular service and CT.

Abstract
INTRODUCTION Conventional practice of parathyroidectomy has been collar incision with bilateral neck exploration and a four-gland evaluation. Our local practice involves simplified parathyroidectomy via mini-incision without routine use of intraoperative adjuncts. The aim of this study is to demonstrate that a good success rate can be achieved, which will hopefully encourage more to undertake minimally invasive parathyroid surgery. MATERIALS AND METHODS A prospective case series of the first 100 patients undergoing minimally invasive parathyroidectomy (MIP) by a single surgeon at a single institution were included. Preoperatively, patients underwent ultrasonography (US) and/or a sestamibi (MIBI) scan for localisation. Parathyroidectomy was performed following an algorithm of intraoperative decisions. Serum calcium and/or parathyroid hormone levels were checked at follow-up. Postoperative normocalcaemia was considered success independent of serum parathyroid hormone levels RESULTS The patients had a median age of 63 years. Of the 100 patients, 83 were female and 17 male. Seven patients had a conversion to bilateral exploration. The mean operative time for unilateral and bilateral exploration was 42.38 minutes and 76.43 minutes respectively. Separately, a MIBI scan and US lateralised the side of the lesion in 82.8% and 79.5% of cases respectively. When US and the MIBI scan agreed, the predictive accuracy of the side of the lesion was 87.5%. The majority of patients (96%) had a successful return to normocalcaemia. No complications were encountered. CONCLUSIONS Excellent results are achievable with simplified MIP even without intraoperative adjuncts. Preoperative localisation is helpful in determining the side of incision. Our technique demonstrates a key principle of surgery: to keep things simple.

Abstract
INTRODUCTION Antibiotics gained a place in the management of acute appendicitis when the bacterial aetiology was demonstrated. Culture swabs were obtained routinely during appendicectomies to guide antibiotic use. Although current antimicrobial therapy use has become prophylactic, empirical and broad spectrum, this age-old practice still remains. Our study questions the value of this traditional practice. MATERIALS AND METHODS All adult and paediatric patients undergoing emergency appendicectomy over three years were retrospectively reviewed. Microbiology and appendix histology reports were retrieved. Occurrence of infective post-operative morbidity was recorded via hospital notes. RESULTS A total of 652 appendectomies (age 1 month to 81 years, median 20 years) were performed in a 36 month period. Four hundred and thirty-five/six hundred and fifty-two (66.7%) had intra-operative swabs taken. One hundred and forty/four hundred and thirty-five (32%) revealed presence ofa pathogens. One hundred and twenty-two/four hundred and thirty-five (28%) were sensitive to broad spectrum empirical antibiotics and only 18/435 (4.1%) cultured resistant strains. Forty-two/six-hundred and fifty-two (6.4%) patients had postoperative infective complications. Twenty-nine/forty-two (68%) had a different organism responsible for this complication. The highest proportion of positive cultures and post-operative infective complications was observed in the extremes of ages (< 10 and > 50 years) and in gangrenous appendicitis. CONCLUSION A majority of intra-operative swabs were negative or isolated commensal flora. Pathogens causing postoperative morbidity were frequently different from those isolated intra-operatively. None of the patients had a change of management based on the swab results. Hence routine intra-peritoneal swabs remains of little clinical value.

Right-sided Bochdalek hernia obstructing in an adult: case report and review of the literature. Hernia 2007; 11:359-62.

Abstract
Bochdalek hernias on the right side of the diaphragm are very rarely diagnosed in adults. We review a case of a 35-year-old female who presented acutely with intestinal obstruction. Plain and cross-sectional imaging identified a large right-sided Bochdalek hernia, containing colon, causing a mechanical obstruction and, surprisingly, concurrent appendicitis. The patient underwent an emergency laparotomy. At surgery the colon was reduced and was viable. The diaphragmatic defect was repaired using non-absorbable sutures and an appendicectomy was then performed for purulent appendicitis. She made an uneventful recovery and remains well at 9-month follow-up. We discuss what we believe to be the first reported case of an obstructed right-sided Bochdalek's hernia associated with appendicitis in an adult and review the published literature on this rare condition.
