Abstract
BACKGROUND Older age and frailty are associated with worse postoperative outcomes and prolonged length of stay (LOS). In this study, we aimed to analyze the long-term outcomes after the implementation of our geriatric surgical service (GSS). METHODS This was a single-center retrospective study from July 2010 to December 2021 on patients aged ≥75 years or patients aged ≥65 years with frailty. Our GSS includes multidisciplinary assessment and optimization by specialized nurses, physiotherapists, anesthetists, dietitians, and geriatricians. Cumulative sum (CUSUM) analysis was used to assess the performance of our GSS. Our primary outcome was defined as the presence of 30-day mortality, prolonged LOS ≥ 14 days, and/or >10% decrease in the modified Barthel Index at 6 weeks, which depicts the failure of GSS. A downsloping CUSUM curve implies consecutive cases of success. RESULTS There were 233 patients with a mean age of 79.0 ± 4.9 years; of these, 73 patients (31.3%) were frail. The overall 30-day mortality (1.7%), Clavien-Dindo ≥ grade IIIA complications (12.0%), and LOS (median, 7.0 days) were low. The CUSUM analysis showed 3 phases with overall sustained improvement in outcomes. Transient inconsistency in the second phase (during midimplementation of GSS) may be due to the early adoption of laparoscopic surgery (44.6% vs 24.1%; adjusted P =.031) and expansion of service to include patients with higher perioperative risks (weighted Charlson Comorbidity Index score ≥4: 64.9% vs 38.0%; adjusted P =.002) in the second period compared with the first period. The outcomes subsequently improved in the third phase after overcoming the learning curve. CONCLUSION Our GSS showed sustained performance over the past decade. Good quality surgery and surgeon-led geriatric service are paramount for good postoperative outcomes.

Abstract
Introduction Singapore instituted lockdown measures from 7 February 2020 to 1 June 2020 in response to the coronavirus disease 2019 (COVID-19) pandemic. Methods A retrospective analysis of cases from the national trauma registry was carried out comparing the lockdown period (from 7 February 2020 to 1 June 2020) to the pre-lockdown period (from 7 February 2019 to 1 June 2019). Data extracted included the volume of Tier 1 (injury severity score [ISS] >15) and Tier 2 (ISS 9-15) cases and epidemiology. Subgroup analysis was performed for Tier 1 patient outcomes. Results Trauma volume decreased by 19.5%, with a 32% drop in Tier 1 cases. Road traffic and workplace accidents decreased by 50% (P < 0.01), while interpersonal violence showed an increase of 37.5% (P = 0.34). There was an 18.1% decrease in usage of trauma workflows (P = 0.01), with an increase in time to intervention for Tier 1 patients from 88 to 124 min (P = 0.22). Discharge to community facilities decreased from 31.4% to 17.1% (P < 0.05). There was no increase in inpatient mortality, length of stay in critical care or length of stay overall. Conclusion There was an overall decrease in major trauma cases during the lockdown period, particularly road traffic accidents and worksite injuries, and a relative increase in interpersonal violence. Redeployment of manpower and hospital resources may have contributed to decreased usage of trauma workflows and community facilities. In the event of further lockdowns, it is necessary to plan for trauma coverage and maintain the use of workflows to facilitate early intervention.

Abstract
Introduction: Sarcopenia, defined as low skeletal muscle mass and poor muscle function, has been associated with worse postoperative recovery. This study aims to evaluate the significance of low muscle mass in the elderly who require emergency surgeries and the postoperative outcomes.
Method: Data from the emergency laparotomy database were retrieved from Khoo Teck Puat Hospital, Singapore, between 2016 and 2019. A retrospective analysis was performed on patients aged 65 years and above. Data collected included skeletal muscle index (SMI) on computed tomography scan, length of stay, complications and mortality. Low muscle mass was determined based on 25th percentile values and correlation with previous population studies.
Results: A total of 289 patients were included for analysis. Low muscle mass was defined as L3 SMI of <22.09cm2/m2 for females and <33.4cm2/m2 for males, respectively. Seventeen percent of our patients were considered to have significantly low muscle mass. In this group, the length of stay (20.8 versus 16.2 P=0.041), rate of Clavien-Dindo IV complications (18.4% vs 7.5% P=0.035) and 1-year mortality (28.6% vs 14.6%, P=0.03) were higher. Further multivariate analysis showed that patients with low muscle mass had increased mortality within a year (odds ratio 2.16, 95% confidence interval 1.02–4.55, P=0.04). Kaplan-Meier analysis also shows that the 1-year overall survival was significantly lower in patients with low muscle mass.
Conclusion: Patients with low muscle mass have significantly higher post-surgical complication rates and increased mortality.

Abstract
INTRODUCTION The standard protocol for exsanguinating trauma patients involves initial evaluation and resuscitation in the emergency department which then sets the stage for subsequent definitive care and disposition. This involves major coordination and mobilisation of resources which may cause a delay in intervention especially when most of these cases present after office hours. Our centre has employed a second-tier activation system (CHOP protocol) that immediately mobilises all respective trauma specialists including interventional radiologists and allows rapid access to the operating room. OBJECTIVE We hypothesised that exsanguinating patients managed by CHOP protocol have better overall outcome and survival. METHODS We identified trauma patients that fulfilled CHOP criteria from 2016 to 2019 and divided them into two groups: preCHOP (standard protocol) and CHOP. Data was extracted from a prospectively maintained trauma registry. Demographics, injury pattern and in-hospital data were analysed. The key outcome studied was the impact of CHOP protocol on the mortality rate. Success and failure of the two groups were analysed using CUSUM methodology. RESULTS Thirty-seven patients were managed by CHOP protocol since its introduction in March 2018 compared to 36 patients who underwent standard protocol. Majority of the cases were blunt trauma (89% CHOP vs 92% preCHOP). The mean Injury Severity Score was 37 for CHOP group and 39 for preCHOP group. We observed a significant improvement in time to intervention in CHOP patients (78 min vs 113 min), both during and after office hours. CHOP patients had lower mortality compared to preCHOP group (11% vs 31%) and the effectiveness of the protocol was seen in achieving significantly lower mortality compared to the predicted model. CHOP protocol was able to produce a consistent trend of desired outcomes leading to the CUSUM curve exhibiting a sustained downward slope. CONCLUSION The CHOP protocol, a relatively novel system in the local context, was able to achieve sustained improved outcomes compared to standard protocol. The CUSUM analysis concurred that implementation of CHOP protocol has helped to achieve consistent desired outcomes. It also suggested that the uptake and use of this protocol has integrated well into the existing workflow.

Abstract
BACKGROUND Laparoscopic ventral hernia repair (LVHR) has been increasing in popularity over the years. Seroma formation is a common complication of LVHR. The aim of this study is to review the current evidence on seroma prevention strategies following LVHR. METHODS A systematic search of PubMed, Embase (1946-13 February 2019) and Medline (1946-13 February 2019) databases was conducted using terms which include "seroma", "hernia, ventral" and "laparoscopy". All studies are comparative retrospective or prospective human adult studies in peer-reviewed journals describing at least one intra-operative intervention designed to decrease the rate of seroma formation in laparoscopic ventral hernia repair. RESULTS The database searches identified 3762 citations, and 21 studies were included for final analysis. Five studies compared the different methods of mesh fixation, nine studies compared primary defect closure (PFC) and bridged repair, two studies compared the effect of different types of meshes, two studies looked into the use of electrical cauterization, one study compared single- site laparoscopy with conventional laparoscopy, one study looked into the use of fibrin sealant and one study compared transabdominal preperitoneal placement of mesh with conventional repair. PFC appears to be the most promising with large studies showing a low rate of seroma formation with additional benefits of decreasing wound infection and recurrence rate. Cauterisation of hernia sac and injection of fibrin sealant also show promising results but are mainly derived from small studies. Other strategies did not demonstrate benefit. CONCLUSION Currently, primary fascial closure appears to be the most promising strategy available to decrease seroma formation after LVHR based on the results of large studies. Other promising strategies that decrease dead space such as cauterisation of the sac and fibrin sealant injection will require further multicentre trials to confirm benefit before an increase in operative time and cost can be justified for their routine use.

Abstract
BACKGROUND Rib fractures are common sequelae after blunt chest wall trauma. They can occur in isolation or association with life-threatening injuries to the head, thorax, and abdomen and may be complicated by hemothorax, pneumothorax, or lung contusions. Contiguous rib fractures can result in flail chest, which is associated with increased morbidity and mortality. This study aims to compare the risk factors, treatment modalities, and outcomes between patients with flail chest and nonflail chest postblunt trauma. PATIENTS AND METHODS Data were retrospectively collected from all patients admitted with rib fractures from January 2016 to December 2016 to the Department of General Surgery, Khoo Teck Puat Hospital, Singapore. The outcomes identified were mortality, pain scores on injury day 1, 3, 5, and 7, injury severity score, duration of mechanical ventilation, worst partial pressure arterial oxygen/fraction of inspired oxygen (PaO2/FiO2) ratio, length of intensive care unit (ICU) stay, and pulmonary complications. RESULTS Motor vehicle accident was the most common cause of rib fractures (63.1%, n = 123). Patients with flail chest had more associated pneumothorax (53.8% vs. 35.2%) and lung contusions (53.8% vs. 30.2%) compared to those without flail chest and underwent more investigations such as inpatient-computed tomography scans (76.9% vs. 59.3%), interventions such as chest tube insertion (61.5% vs. 19.8%), and ICU admission (46.1 vs. 13.7%). Patients also had higher pain scores, used more analgesic modalities, and had increased inpatient mortality (30.8% vs. 4.4%). CONCLUSION Flail chest is associated with higher morbidity and mortality. Proactive management from a multidisciplinary team such as identification of high-risk patients in particular patients with flail chest, early admission to critical care, and protocols including multimodal pain management, respiratory support, and rehabilitation should be instituted.

Abstract
Introduction. The aim of this study was to compare the outcomes between laparoscopic and open omental patch repair (LOPR versus OR) in patients with similar presentation of perforated peptic ulcer (PPU). The secondary aim was to evaluate the outcomes according to the severity of peritonitis. Methods. All patients who underwent omental patch repair at two university-affiliated institutes between January 2010 and December 2014 were reviewed. Matched cohort between LOPR and OR groups was achieved by only including patients that had ulcer perforation <2 cm in size and symptoms occurring <48 hours. Outcome measures were defined in accordance with length of stay (LOS), postoperative complications, and mortality. Results. 148 patients met the predefined inclusion criteria with LOPR performed in 40 patients. Outcome measures consistently support laparoscopic approach but only length of hospital stay (LOS) achieved statistical significance (LOPR 4 days versus OR 5 days, p < 0.01). In a subgroup analysis of patients with MPI score >21, LOPR is also shown to benefit, particularly resulting in significant shorter LOS (4 days versus 11 days, p < 0.01). Conclusion. LOPR offers improved short-term outcomes in patients who present within 48 hours and with perforation size <2 cm. LOPR also proved to be more beneficial in high MPI cases.

Abstract
The adoption of endoscopic surgery continues to expand in clinical situations with the recent natural orifice transluminal endoscopic surgery technique enabling abdominal organ resection to be performed without necessitating any skin incision. In recent years, the development of numerous devices and platforms have allowed for such procedures to be carried out in a safer and more efficient manner, and in some ways to better simulate triangulation and surgical tasks (e.g., suturing and dissection). Furthermore, new novel techniques such as submucosal tunneling, endoscopic full-thickness resection and hybrid endo-laparoscopic approaches have further widened its use in more advanced diseases. Nevertheless, many of these new innovations are still at their pre-clinical stage. This review focuses on the various innovations in endoscopic surgery, with emphasis on devices and techniques that are currently in human use.

Abstract
The radiographs of 115 anterior shoulder dislocations (100 patients; 74 males, 26 female were reviewed to assess the radiographic views used in the management of this dislocation. Eighty-eight patients (88%) had only the anteroposterior (AP) view, 10 patients had 2 radiographic views taken and only 2 patients had three radiographic views. Hill-Sachs lesions were found in 18%, and glenoid rim fractures in 3% of the patients. A greater tuberosity fracture was found in 18% of the patients. Therefore, the current practice in the management of an acute anterior shoulder dislocation appears to be to perform a single view (AP) pre-reduction radiograph to confirm the diagnosis and a single view (AP) post reduction radiograph to confirm reduction after a close manipulative reduction has been performed. This practice is likely to result in an underestimate of associated Hill Sachs lesion and glenoid rim fractures, but not greater tuberosity fractures.

Abstract
The case notes of 102 patients (117 shoulder dislocations) were reviewed retrospectively to improve the understanding of the epidemiology of this common injury. Eighty-one dislocations were primary and 36 dislocations were second or recurrent dislocations. The age distribution was characterized by a peak in male patients aged between 21-30 years. The mean age for males was 30.5 years and 47.7 years for females. The male:female ratio in first time dislocations was 5:2, while it was 5:1 in recurrent dislocations. Ninety-eight percent were anterior dislocations and 2% were posterior dislocations. Greater tuberosity fractures were found in 17 patients and almost half of these patients were aged between 41-50 years. The most common cause of first time dislocation was a direct blow or fall onto the shoulder, accounting for 42 patients (55%). The majority of these patients were aged 40 years and above. Next common cause was motor vehicle accident which occurred mostly in the younger age group. Dislocations due to sporting injuries accounted for only 5.3% of all first time dislocations. Nearly 97% were successfully reduced without a general anaesthesia. Seventy-seven percent of the patients had their shoulders immobilized after reduction, mostly with body strapping only. Fifteen patients (14.7%) were referred for physiotherapy for stiffness. Few operations were performed for recurrent dislocations but surgery does not appear to be well accepted as yet by our patients.

Abstract
A retrospective study was conducted to determine the incidence of nerve injuries in anterior dislocations of the shoulder and to determine if a neurological examination is routinely performed in such cases. One hundred and fifteen shoulder dislocations in 100 patients (74 males, 26 females; mean age 35+/-18 years) were reviewed. Eighty-seven patients were examined for neurological injuries prior to reduction and 8 of these patients (9.2%) were found to have sustained neurological injuries. Following reduction, neurological examination was performed in 85 patients. Three patients who were not examined initially prior to reduction were subsequently found to have nerve injuries after reduction. Seven patients (7%) were not examined for neurological injury both before and after reduction of the dislocation. Eleven patients were found to have sustained nerve injuries in the final analysis. Axillary nerve injuries were the most common, occurring in 8 patients. In conclusion, nerve injuries are common in shoulder dislocations. The importance of performing and documenting the findings of neurological examination anterior shoulder dislocations needs to be reiterated.
