Background: Colorectal cancer is the third most common cancer and the second highest cause of cancer-related mortality worldwide. About 5%-10% of patients are diagnosed with locally advanced rectal cancer (LARC) on presentation. For LARC invading into other structures ( T4b), multivisceral resection (MVR) and/or pelvic exenteration (PE) remains the only potential curative surgical treatment.

Rectosigmoid intussusception is a rare cause of bowel obstruction, accounting for only approximately 1%-2% of all bowel obstruction cases. While intussusception in adults typically occurs intra-abdominally and presents with signs and symptoms of intestinal obstruction, in rare cases, it can mimic a rectal prolapse if the intussusceptum protrudes through the anal canal. We herein report a case where an octogenarian woman presented with rectosigmoid intussusception through the anal canal, due to a sigmoid colon submucosal lipoma, who eventually required an open Hartmann's procedure.

Spontaneous haemoperitoneum is a rare condition with a variety of aetiologies. Regardless of the cause, it is invariably a life-threatening condition that requires urgent diagnosis and management. The most common causes of spontaneous haemoperitoneum include gynaecological, hepatic, splenic and vascular causes.

Background: Complete mesocolic excision with D3 lymph node dissection in right-sided colon cancer is associated with improved oncological outcomes, but can potentially be associated with higher rates of complications compared to conventional D2 right hemicolectomy. This study aims to evaluate the oncological and perioperative outcomes of patients who underwent D3 right hemicolectomy, comparing to conventional right hemicolectomy.

Methods: From 2015 to 2020, 360 patients underwent right hemicolectomy for colonic malignancies.

: To evaluate outcomes after transmetatarsal amputation (TMA) in peripheral arterial disease (PAD) limb salvage in an Asian population and identify risk factors associated with TMA failure. : A retrospective review of 147 patients with PAD, who had undergone TMA between 2008 and 2014, was carried out. Univariate and multivariate analysis were used to identify predictors of TMA failure.

Synopsis of recent research by authors named "Ming Ngan Aloysius Tan"

  • - Ming Ngan Aloysius Tan's recent research primarily investigates surgical interventions and outcomes for complex gastrointestinal conditions, particularly focusing on rectal cancer and its advanced stages, as seen in his study on the feasibility and safety of minimally invasive multivisceral resection for T4b rectal cancer.
  • - His research also addresses rare presentations of intestinal issues, such as rectosigmoid intussusception caused by a submucosal lipoma, highlighting the importance of accurate diagnosis and management in adult bowel obstruction cases.
  • - Additionally, Tan explores the comparative outcomes of different surgical techniques, such as D2 vs. D3 right hemicolectomy for colon cancer, contributing to the understanding of oncological and perioperative results in surgical oncology, especially in Asian populations.
