The impact of short-course total neoadjuvant therapy, long-course chemoradiotherapy, and upfront surgery on the technical difficulty of total mesorectal excision: an observational study with an intraoperative perspective.

Purpose: Total neoadjuvant therapy (TNT) is becoming the standard of care for locally advanced rectal cancer. However, surgery is deferred for months after completion, which may lead to fibrosis and increased surgical difficulty. The aim of this study was to assess whether TNT (TNT-RAPIDO) is associated with increased difficulty of total mesorectal excision (TME) compared with long-course chemoradiotherapy (LCRT) and upfront surgery.

Diagnosing Sarcopenia with AI-Aided Ultrasound (DINOSAUR)-A Pilot Study.

Sarcopenia has been recognized as a determining factor in surgical outcomes and is associated with an increased risk of postoperative complications and readmission. Diagnosis is currently based on clinical guidelines, which includes assessment of skeletal muscle mass but not quality. Ultrasound has been proposed as a useful point-of-care diagnostic tool to assess muscle quality, but no validated cut-offs for sarcopenia have been reported.

Colonic stenting: is the bridge to surgery worth its cost? A cost-effectiveness analysis at a single Asian institution.

Purpose: In patients with acute left-sided colonic obstruction, stenting can convert an emergency operation into a semi-elective procedure. However, its use continues to be debated. We performed a cost-effective analysis using our institution's experiences.

Analgesia efficacy of erector spinae plane block in laparoscopic abdominal surgeries: a systemic review and meta-analysis.

Background: Multimodal analgesia is now widely practised to minimise postoperative opioid consumption while optimising pain control. The aim of this meta-analysis was to assess the analgesic efficacy of erector spinae plane block (ESPB) in patients undergoing laparoscopic abdominal surgeries. This will be determined by perioperative opioid consumption, subjective pain scores, and incidences of postoperative nausea and vomiting.

Evaluating the surgical trainee ergonomic experience during minimally invasive abdominal surgery (ESTEEMA study).

Minimally invasive abdominal surgery (MAS) can exert a physical cost. Surgical trainees spend years assisting minimally-invasive surgeries, increasing the risk of workplace injury. This prospective questionnaire-based cohort study was conducted amongst general surgery residents in Singapore.

Safe discharge for patients admitted for lower gastrointestinal bleeding (LGITB): derivation and validation of a novel scoring system.

Aim: Bleeding from the lower gastrointestinal tract (LGITB) is a common clinical presentation. Recent guidelines have recommended for incorporation of clinical risk assessment tools in the management for LGITB. We derived and validated a novel clinical scoring system to predict safe discharge after LGITB admission, and compared it to other published scoring systems in current literature.

Ureteral Injury.

A 70-year-old man underwent laparoscopic low anterior resection for a rectal adenocarcinoma after neoadjuvant chemoradiotherapy. Postoperatively, the patient had high drain volume output, with 800 mL of clear serous fluid being drained on the second postoperative day. Drain creatinine returned as 300 mmol/L, with a corresponding serum creatinine of 100 mmol/L.

Pre-operative erector spinae plane block should be considered a viable option for laparoscopic colectomies.

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.

The Role and Effect of Multimodal Prehabilitation Before Major Abdominal Surgery: A Systemic Review and Meta-Analysis.

Background: For patients undergoing abdominal surgery, multimodal prehabilitation, including nutrition and exercise interventions, aims to optimize their preoperative physical and physiological capacity. This meta-analysis aims to explore the impact of multimodal prehabilitation on surgical and functional outcomes of abdominal surgery.

Methods: Medline, Embase and CENTRAL were searched for articles about multimodal prehabilitation in major abdominal surgery.

Systematic review and meta-analysis of postoperative pain and symptoms control following laser haemorrhoidoplasty versus Milligan-Morgan haemorrhoidectomy for symptomatic haemorrhoids: a new standard.

Purpose: Haemorrhoidal disease (HD) plagues one in every ten people, with a plethora of surgical treatment modalities, of which laser haemorrhoidoplasty (LHP) is a relatively novel option. This systematic review and meta-analysis objectively evaluated the efficacy, safety, and tolerability of LHP compared against conventional (Milligan-Morgan) open haemorrhoidectomy (CoH).

Method: A comprehensive search of MEDLINE, EMBASE, CENTRAL, and Google Scholar was conducted.

Structured presurgery prehabilitation for aged patients undergoing elective surgery significantly improves surgical outcomes and reduces cost: A nonrandomized sequential comparative prospective cohort study.

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.

Paradigm shift in gastrointestinal surgery - combating sarcopenia with prehabilitation: Multimodal review of clinical and scientific data.

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.

Colorectal cancer surgery in Asia during the COVID-19 pandemic: A tale of 3 cities.

Purpose: The COVID-19 pandemic has put tremendous strain on healthcare systems. Surgical societies worldwide have advised minimizing non-essential surgeries in order to preserve hospital resources. Given the medical resources and COVID-19 incidence between countries across the world differ, so should colorectal practices.

A prognostic score predicting survival following emergency surgery in patients with metastatic colorectal cancer.

Background: Survival of patients with metastatic colorectal cancer (mCRC) varies. We aim to develop a prognostic score for mCRC after emergency surgery to guide treatment decisions.

Methods: Newly diagnosed mCRC patients who presented with primary tumor-related complications and underwent emergency surgery between January 1999 and December 2013 were included.

Study Protocol for the Use of Conventional Open Haemorrhoidectomy versus Laser Haemorrhoidoplasty in the Treatment of Symptomatic Haemorrhoids: A Randomized Controlled Trial.

Background: Haemorrhoids result in a variety of symptoms that cause significant patient anxiety. Treatment has long been associated with post-operative complications, which cause significant symptoms and may result in readmissions. The open conventional haemorrhoidectomy (COH) is still regarded as the gold standard treatment for non-circumferential grade II-IV haemorrhoids.

Primary Tumor-Related Complications and Salvage Outcomes in Patients with Metastatic Rectal Cancer and an Untreated Primary Tumor.

Background: For rectal cancer with unresectable metastases, current practice favors omitting interventions directed at the primary tumor in asymptomatic patients.

Objective: This study aimed to determine the proportion of patients with primary tumor-related complications, characterize salvage outcomes, and measure survival in patients with metastatic rectal cancer who did not undergo upfront intervention for their primary tumor.

Design: This is a retrospective analysis.
