ChatGPT as a patient education tool in colorectal cancer-An in-depth assessment of efficacy, quality and readability.

Aim: Artificial intelligence (AI) chatbots such as Chat Generative Pretrained Transformer-4 (ChatGPT-4) have made significant strides in generating human-like responses. Trained on an extensive corpus of medical literature, ChatGPT-4 has the potential to augment patient education materials. These chatbots may be beneficial to populations considering a diagnosis of colorectal cancer (CRC).

Emotional Intelligence as a Component of Surgical Coaching: A Scoping Review.

Objective: Surgical coaching has become more widespread and involves both technical and nontechnical skills. Emotional Intelligence (EI) is an important nontechnical skill and is associated with leadership skills, increased job satisfaction and superior nontechnical skills. This scoping review aimed to explore the use of EI as a component of surgical coaching.

Lymph node ratio prognosticates overall survival in patients with stage IV colorectal cancer.

Background: Lymph node ratio (LNR) is suggested to address the shortcomings of using only lymph node yield (LNY) or status in colorectal cancer (CRC) prognosis. This study explores how LNR affects survival in patients with metastatic colorectal cancer (mCRC), seeking to provide clearer insights into its application.

Methods: This observational cohort study investigated stage IV patients with CRC (1995-2021) who underwent an upfront resection of their primary tumour at Concord Hospital, Sydney.

Tissue morphometric measurements do not predict survival following colorectal cancer surgery.

Background: Ex vivo tissue morphometric (TM) measurements have been proposed as a quality marker for colorectal cancer (CRC) surgery. However, their survival associations require clarification. This study aimed to evaluate the feasibility of capturing TM measurements based on ex vivo fresh specimen images and explore the association between these TM measurements and survival outcomes.

Low anterior resection syndrome phenotypes-Different symptom profiles for different patients.

Aim: Attention is increasingly being turned to functional outcomes as being central to colorectal cancer (CRC) survivorship. The current literature may underestimate the impact of evacuatory dysfunction on patient satisfaction with bowel function after anterior resection (AR) for CRC. The aim of this study was to investigate the impact of post-AR symptoms of storage and evacuatory dysfunction on patient satisfaction and health-related quality of life (HRQoL).

Major low anterior resection syndrome has equivalent health-related quality of life implications as having a permanent colostomy.

Background: The literature is inconclusive when comparing health-related quality of life following restorative anterior resection (AR) compared with abdominoperineal resection (APR). Consideration of functional outcomes may explain this inconsistency. The aim of this study was to compare health-related quality of life in patients post-anterior resection, stratified by low anterior resection syndrome score, and post-abdominoperineal resection patients.

The use of adjuvant chemotherapy is not associated with recurrence or cancer-specific death following curative resection for stage III rectal cancer: a competing risks analysis.

Background: The role of adjuvant chemotherapy (AC) in stage III rectal cancer (RC) has been argued based on evidence from its use in colon cancer. Previous trials have analysed disease-free and overall survivals as endpoints, rather than disease recurrence. This study compares the competing risks incidences of recurrence and cancer-specific death between patients who did and did not receive AC for stage III RC.

Splenic flexure cancer survival: a 25-year experience and implications for complete mesocolic excision (CME) and central vascular ligation (CVL).

Background: The management of splenic flexure cancers (SFCs) in the era of complete mesocolic excision (CME) and central vascular ligation (CVL) is challenging because of its variable lymphatic drainage. This study aimed to compare survival outcomes for SFCs and non-SFCs, and better understand the clinicopathological characteristics which may define a distinct SFC phenotype.

Methods: An observational cohort study at Concord Hospital, Sydney was conducted with patients who underwent resection for colon adenocarcinoma (1995-2019).

Right hemicolectomy anastomotic leak study: a review of right hemicolectomy in the binational clinical outcomes registry (BCOR).

Backgrounds: Surgery remains mainstay management for colon cancer. Post-operative anastomotic leak (AL) carries significant morbidity and mortality. Rates of, and risk factors associated with AL following right hemicolectomy remain poorly documented across Australia and New Zealand.

Endoscopic findings after CT proven acute diverticulitis: a systematic review and meta-analysis.

Background: Traditionally, international guidelines recommend patients with acute diverticulitis should be followed up with a colonoscopy 6-8 weeks after discharge. However, the need for an interval colonoscopy has been increasingly challenged in the setting of computed tomography (CT). Previous meta-analyses have included studies which combined suspected rather than imaging confirmed diverticulitis and often without correlation with endoscopic findings.

Recurrence and colon cancer-specific death in patients with large bowel obstruction requiring urgent operation: a competing risks analysis.

Aim: Clinical presentation with large bowel obstruction has been proposed as a predictor of poor long-term oncological outcomes after resection for colorectal cancer. This study examines the association between obstruction and recurrence and cancer-specific death after resection for colon cancer.

Method: Consecutive patients who underwent resection for colon cancer between 1995 and 2014 were drawn from a prospectively recorded hospital database with all surviving patients followed for at least 5 years.

Apical Node Involvement Does Not Influence Prognosis After Potentially Curative Resection for Stage III Colorectal Cancer: A Competing Risks Analysis.

Objective: To examine the independent prognostic value of ALN status in patients with stage III CRC.

Summary Of Background Data: Early CRC staging classified nodal involvement by level of involved nodes in the operative specimen, including both locoregional and apical node status, in contrast to the American Joint Committee on Cancer/tumor nodes metastasis (TNM) system where tumors are classified by the number of nodes involved. Whether ALN status has independent prognostic value remains controversial.

Ileal Pouch-Anal Anastomosis for Ulcerative Colitis: An Australian Institution's Experience.

Purpose: We report outcomes and evaluate patient factors and the impact of surgical evolution on outcomes in consecutive ulcerative colitis patients who had restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) at an Australian institution over 26 years.

Methods: Data including clinical characteristics, preoperative medical therapy, and surgical outcomes were collected. We divided eligible patients into 3 period arms (period 1, 1990 to 1999; period 2, 2000 to 2009; period 3, 2010 to 2016).

Relative effects of direct spread, lymph node metastasis and venous invasion in relation to blood borne distant metastasis present at the time of resection of colorectal cancer.

Conventionally, lymphatic spread is regarded as the principal mechanism by which haematogenous metastasis occurs in colorectal cancer. The aim of this cross sectional study was to determine the relative strengths of direct tumour spread, the presence of lymph node metastasis and histologically demonstrated venous invasion as drivers of haematogenous metastasis diagnosed at the time of resection of colorectal cancer. The data were drawn from a hospital database of consecutive bowel cancer resections between 1995 and 2017 inclusive.

High prevalence of asymptomatic internal hernias after laparoscopic anterior resection in a retrospective analysis of postoperative computed tomography.

Purpose: Internal hernia (IH) after laparoscopic left-sided colorectal resection (small bowel herniating underneath the neo-descending colon) can be a potentially devastating complication, resulting in acute small bowel obstruction or ischemia. IH has been described as a rare occurrence in a few retrospective case series; however, patients undergoing laparoscopic resection seem to be more prone to this complication. We assessed the prevalence of IH in a large cohort of patients who had undergone laparoscopic left-sided colorectal resection for colon or rectal cancer (CRC).

Impact of post-haemorrhoidectomy pain relief checklists on pain outcomes: a randomized controlled trial.

Background: Haemorrhoidectomy is associated with significant post-operative pain which is primarily managed pharmacologically. Whether a non-pharmacological adjunct such as a checklist can improve pain outcomes after an open haemorrhoidectomy has yet to be studied. The purpose of this study was to determine if a patient-completed checklist of prescribed post-haemorrhoidectomy pain medications would improve pain management after surgery.

Review of emotional intelligence in health care: an introduction to emotional intelligence for surgeons.

Background: The aim of this review is to explain the components of emotional intelligence (EI) and explore the benefits within today's health care system with an emphasis on surgery. EI is a person's ability to understand their own emotions and those of the individuals they interact with. Higher individual EI has multiple proposed benefits, such as reducing stress, burnout and increasing work satisfaction.

Competing risks analysis of the association between perioperative blood transfusion and long-term outcomes after resection of colorectal cancer.

Aim: Despite numerous reports over three decades, the association between perioperative blood transfusion and long-term outcomes after resection of colorectal cancer remains controversial. This cohort study used competing risks statistical methods to examine the association between transfusion and recurrence and colorectal cancer-specific death after potentially curative and noncurative resection.

Method: A hospital database provided prospectively recorded clinical, operative and follow-up information.

Immunohistochemistry in screening for heritable colorectal cancer: what to do with an abnormal result.

Recent developments in our understanding of molecular genetics have transformed screening and diagnostic practices for Lynch syndrome. The current standard involves universal tumour analysis of resected colorectal cancer (and ideally polypectomy) specimens using immunohistochemistry and molecular techniques. Patients with abnormal immunohistochemical findings are subsequently referred for definitive mutational testing.
