RESUMO
Introduction: The global rise in ageing populations poses challenges for healthcare systems. By 2030, Singapore anticipates a quarter of its population to be aged 65 or older. This study addresses the dearth of research on frailty's impact on emergency laparotomy (EL) outcomes in this demographic, emphasising the growing significance of this surgical intervention. Method: Conducted at 2 tertiary centres in Singapore from January to December 2019, a retrospective cohort study examined EL outcomes in patients aged 65 or older. Frailty assessment, using the Clinical Frailty Scale (CFS), was integrated into demographic, diagnostic and procedural analyses. Patient data from Tan Tock Seng Hospital and Khoo Teck Puat Hospital provided a comprehensive view of frailty's role in EL. Results: Among 233 participants, 26% were frail, revealing a higher vulnerability in the geriatric population. Frail individuals exhibited elevated preoperative risk, prolonged ICU stays, and significantly higher 90-day mortality (21.3% versus 6.4%). The study illuminated a nuanced connection between frailty and adverse outcomes, underlining the critical need for robust predictive tools in this context. Conclusion: Frailty emerged as a pivotal factor influencing the postoperative trajectory of older adults undergoing EL in Singapore. The integration of frailty assessment, particularly when combined with established metrics like P-POSSUM, showcased enhanced predictive accuracy. This finding offers valuable insights for shared decision-making and acute surgical unit practices, emphasising the imperative of considering frailty in the management of older patients undergoing emergency laparotomy.

BACKGROUND: Emergency laparotomy is associated with high morbidity and significant global health burden. This study aims to compare postoperative outcomes of patients who underwent emergency laparotomy before and after implementation of a emergency laparotomy pathway. METHODS: This is a single-center study of all patients who presented with an acute abdomen and/or conditions requiring emergency laparotomy during pre-emergency laparotomy pathway (retrospective cohort from January 2016 to December 2018) and after the emergency laparotomy pathway (prospective cohort from January 2019 to December 2021). Patients who underwent emergency laparotomy for trauma or vascular surgery were excluded. A 1:1 propensity score matching was performed to address for confounding factors. RESULTS: There were 888 patients (emergency laparotomy pathway, n = 428, and pre-emergency laparotomy pathway, n = 460) in the unmatched cohort. The mean age was 63.0 ± 15.4 years, and 43.8% had predicted mortality >10% using Portsmouth-Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity. The most common indication for emergency laparotomy was intestinal obstruction (30.5%). Overall incidence rates of major morbidity and 30-day mortality were 16.2% and 3.5%, respectively. There were 736 patients (n = 368 patients per arm) after propensity score matching. Demographic characteristics were comparable after propensity score matching. The emergency laparotomy pathway was associated with more patients assessed by geriatric medicine (odds ratio = 15.22; P < .001), reduced major morbidity (odds ratio = 0.63; P = .024), reduced intra-abdominal collection (odds ratio = 0.39; P = .006), and need for unplanned radiological and/or surgical intervention after index emergency laparotomy (odds ratio = 0.63; P = .024). Length of stay and 30-day mortality were comparable between the emergency laparotomy pathway and pre-emergency laparotomy pathway in both the unmatched and propensity score matched cohort. CONCLUSION: Sustained improved postoperative outcomes were achieved 3 years postimplementation of the emergency laparotomy pathway .

PURPOSE: Despite the widespread of ventral hernia repairs globally, the approach method, dissection planes, defect closure, and the choice and placement layer of mesh are an ongoing debate. We reported the details of surgical techniques, safety and feasibility for robot-assisted transabdominal transversalis fascial and preperitoneal repair (R-TATFPP) for small ventral hernia. METHODS: This study included 5 cases of R-TATFPP repair among 22 cases performed by robot-assisted ventral hernia repair from 2018 to 2023 with the approval of the Institutional Review Board at St. Luke's International University and clinical ethical committee at St. Luke's International Hospital (19-R147, 22-012). RESULTS: There were four males and one female, with mean age of 64.4 ± 10.0 years, inclusive of two umbilical and three incisional hernias. Mean height, weight, body mass index (BMI), hernia defect length, width, operation time, console time, and hospital stay were 171.2 ± 11.8 cm, 82.4 ± 13.4 kg, 28.0 ± 2.1 kg/m2, 2.8 ± 1.4 cm, 3.0 ± 1.3 cm, 180 min, 133.8 min, and 2.4 days, respectively. No conversion nor complication was observed except for one acute urinary retention. CONCLUSION: Robot-assisted transversalis fascial and preperitoneal repair was safe and feasible for small ventral hernia with the minimal disruption to the abdominal wall architecture and structures.

Background: Laparoscopic totally extraperitoneal (TEP) inguinal hernia repair (IHR) reduces risk of injury to intraperitoneal structures. Balloon dissection is more costly and has theoretical risk of injury to the surrounding structures compared with telescopic dissection (TD). This study aims to evaluate the learning curve (LC) for TEP IHR with TD of a single surgeon. Methods: This is a 3-year retrospective cohort study from January 2020 to December 2022 on patients who underwent elective laparoscopic TEP unilateral IHR with TD. Exclusion criteria were recurrent inguinal hernia. Cumulative sum (CUSUM) analysis was performed to evaluate the number of cases required to surmount the LC, that is, NLC for operating time (OT) and open conversion. One way analysis of variance was used to perform groupwise comparison. Results: There were 69 patients who underwent laparoscopic TEP unilateral IHR with TD. The median age was 58.0 years (range 24.0-80.0) and body mass index was 23.0 (range 18.6-30.0). Majority of the hernia was indirect (n = 48, 69.6%). The median OT was 70 minutes (range 35-210). Three cases (4.3%) had open conversion. One-year recurrence was 4.2% (n = 1/24). CUSUM analysis showed improvement in OT after the eighth case. However, this was followed by multiple inflection points with no apparent stabilization in OT. Pairwise comparison showed a decrease in OT between cases 18-36 and cases 37-54. There was no incidence of open conversion until the 56th case. Conclusion: Laparoscopic TEP IHR using TD is safe in the absence of a practor. A minimum of 36 cases is required to surmount the initial LC.

Objective: Patients with breast cancer who have indeterminate extra-mammary lesions, for example in lung, liver or bone, without other metastatic lesions pose a clinical dilemma regarding subsequent management. This study aimed to investigate the prevalence, characteristics and outcomes of such lesions detected on initial staging imaging, and address the clinical significance of these incidental findings. Materials and Methods: Medical records of patients with newly diagnosed breast cancer who underwent computed tomography scans and bone scintigraphy between January 1, 2015 and June 30, 2021 were reviewed. Patients with indeterminate extra-mammary lesions on imaging were included. Patients with obvious metastatic disease were excluded. Lesion characteristics, breast cancer staging, duration of follow-up and natural history of disease progression were analysed. Results: The study included 52 patients with indeterminate lesions on pre-operative imaging. The median follow-up duration was 14 (range: 6-41) months. The most common site of occurrence of indeterminate lesions was the lung (60.9%) followed by the liver (26.1%). Forty-six had lesions that remained stable (88.5%), while six (11.5%) had progression to metastatic disease. Out of these six, only two (3.8%) developed metastasis in the same site as the original indeterminate lesion, whereas the remaining four developed metastases in other sites. Conclusion: Patients with breast malignancy found to have indeterminate extra-mammary lesions without obvious distant metastasis on initial staging scans are associated with a small risk of subsequently developing metastatic disease. Although most of these lesions remain quiescent, surveillance imaging is recommended because a small but significant proportion of patients with such lesions eventually harbour actual metastatic disease.
RESUMO
AIM: Emergency laparotomy (EL) is a common surgery associated with high morbidity and mortality. An enhanced care pathway incorporates evidence-based care bundles with the aim of providing standardized perioperative care. Prior to 2019, EL management in our institution was not standardized. This study aims to assess whether implementation of a transdisciplinary perioperative Emergency Laparotomy (ELAP) pathway improves clinical and efficiency outcomes of EL. METHODS: A prospective single-center audit was undertaken between 1 January and 31 December, 2019 following the implementation of the ELAP pathway. Comparisons were made with retrospective data from the preimplementation period between 1 January and 31 December, 2017. Demographics and clinical and efficiency outcomes were compared for patients (age > 16 years old) requiring EL for acute abdominal conditions. RESULTS: There were 152 and 162 patients from preimplementation and postimplementation periods, respectively. There was a nonsignificant reduction of 30-day mortality in the intervention group receiving perioperative pathway care compared with the preintervention group (3.1% versus 5.3%, respectively; P = 0.40). There was a decrease in postoperative complications in the intervention group, in particular for Clavien-Dindo IV complications (11.2% versus 3.1%, p < 0.01). Efficiency outcomes improved postimplementation with increased consultant surgeon and anesthetist presence in operating theater and postoperative geriatric assessment for elderly patients. There was an overall reduction in cost of hospital stay from S$32,128 to $27,947 (p = 0.24). CONCLUSION: Implementation of a transdisciplinary perioperative care pathway was associated with significant reduction in postoperative complications, improvement in 30-day mortality and efficiency outcomes at reduced hospital costs for patients following EL in our institution.
RESUMO
Intercostal artery bleeding from trauma can result in potentially fatal massive hemothorax. Traumatic hemothorax has traditionally been treated with tube thoracostomy, video-assisted thoracoscopic surgery, or thoracotomy. Transcatheter arterial embolization (TAE), a well-established treatment option for a variety of acute hemorrhage is not widely practiced for the management of traumatic hemothorax. We present 2 cases of delayed massive hemothorax following chest trauma which were successfully managed by transarterial embolization of intercostal arteries. The published studies are reviewed and a systematic approach to the selection of patients for TAE versus emergency thoracotomy is proposed.

The aging population is an increasing healthcare concern in developing countries. In Singapore, 25% of the local population are expected to be older than 65 years old by 2030. Colorectal cancer (CRC) is ranked third most diagnosed cancers worldwide with up to 1.8 million new cases diagnosed in 2018. 60% of newly diagnosed CRC are among patients who are 70 years or older and hence majority of these patients will invariably face challenges with frailty and multiple comorbidities that require appropriate assessment and stratification. The standard of care in patients with stage I or II CRC is surgery with curative intent. For patients with stage III CRC, upfront surgical resection of tumor along with adjuvant chemotherapy is the internationally recommended treatment approach. As for those patients with metastatic disease, they are usually managed within a multidisciplinary team and considered for surgical resection if deemed feasible. Elderly patients are mostly burdened with frailty, functional dependency and existing co-morbidities, all of which are predictors of early postoperative mortality and morbidity in patients with CRC. This article thus aims to review existing evidence to discuss the intricate decision-making process for the surgical management of elderly patient with CRC.
RESUMO
PURPOSE: Low vitamin D status is prevalent worldwide and has been linked to a variety of pathologies including obesity in adults. The severity of vitamin D deficiency amongst the overweight and obese Singaporeans is not well documented. The purpose of this prospective observational study was to assess the prevalence and determinants of vitamin D deficiency in a multi-ethnic Asian population referred for weight management, including those seeking bariatric surgery. MATERIALS AND METHODS: This was a cross-sectional study conducted among 111 consecutive subjects referred to a single institution weight management service in Singapore. The data collected included their anthropometric data, body mass index (BMI), body fat percentage, waist circumference, 25-hydroxyvitamin D [25(OH)D] and other bone turnover markers. RESULTS: The average BMI among the 111 subjects was 40.1 ± 8.2 kg/m2 and mean age of 40 ± 10 years. Vitamin D deficiency was found in 75.7% of the population. There was a significant negative association of vitamin D with adiposity markers including BMI (r = - 0.31), body fat percentage (r = - 0.34) and waist circumference (r = - 0.26). Predictors of vitamin D deficiency included age > 50 years, female gender, waist circumference and body fat percentage. CONCLUSION: Vitamin D deficiency is prevalent among this target population in Singapore regardless of ethnicity. In particular, the elderly, females, those with larger waist circumference and body fat percentage were significantly associated with lower serum 25(OH)D level. Hence, routine screening for the overweight and obese subjects in multi-ethnic Singapore seeking weight management is indicated.

This report highlights the rare occurrence of a huge gangrenous Meckel's diverticulum in an adult, which was managed successfully with laparoscopic resection. A 45-year-old woman presented with a one-day history of right iliac fossa pain with fever and vomiting. Computed tomography showed a huge gangrenous Meckel's diverticulum. The patient underwent laparoscopic exploration and extracorporeal stapled resection of the Meckel's diverticulum. This case serves to highlight the safety and feasibility of performing a laparoscopic resection of a huge gangrenous Meckel's diverticulum in an adult.
