OBJECTIVES: The cell cycle regulator cyclin D1 plays an important role in parathyroid tumourigenesis. The NciI polymorphism in exon 4 has recently been associated with early onset of hereditary nonpolyposis colorectal cancer and is a prognostic indicator of nonsmall cell lung cancer and squamous cell carcinomas. Furthermore, a limited study of 28 primary hyperparathyroidism (pHPT) patients display

OBJECTIVE: Hyperparathyroidism (HPT) refers to states of excessive production of parathyroid hormone (PTH). The eukaryotic cell cycle is driven forward by cyclins and their cyclin-dependent kinase (CDK) partners. Cyclin-dependent kinase inhibitors (CKIs), which generally inhibit cell cycle progression, modulate the activity of cyclin-CDK complexes.DESIGN: In order to quantify the expression of the

Vitamin D receptor (VDR) and 25-hydroxyvitamin D3 1-alpha-hydroxylase expression have recently been shown to be upregulated in several tumors and thought to represent an important endogenous response to tumor progression. Little is known about the expression of these proteins in thyroid carcinoma, although previous reports have documented evidence of the biological effect of vitamin D in thyroid c

SARS-CoV-2 has been associated with an increased rate of venous thromboembolism in critically ill patients. Since surgical patients are already at higher risk of venous thromboembolism than general populations, this study aimed to determine if patients with peri-operative or prior SARS-CoV-2 were at further increased risk of venous thromboembolism. We conducted a planned sub-study and analysis fro

We aimed to determine the impact of pre-operative isolation on postoperative pulmonary complications after elective surgery during the global SARS-CoV-2 pandemic. We performed an international prospective cohort study including patients undergoing elective surgery in October 2020. Isolation was defined as the period before surgery during which patients did not leave their house or receive visitors

Carcinoembryonic antigen (CEA) is not normally produced in significant quantities after birth but is elevated in colorectal cancer. The aim of this review was to define the current role of CEA and how best to investigate patients with elevated CEA levels. A systematic review of CEA was performed, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

BACKGROUND: Rates of parastomal hernia following stoma formation remain high. Previous systematic reviews suggested that prophylactic mesh reduces the rate of parastomal hernia; however, a larger trial has recently called this into question. The aim was to determine whether mesh placed at the time of primary stoma creation prevents parastomal hernia.METHODS: The Cochrane Central Register of Contro

BACKGROUND: Mesenteric panniculitis (MP) is a rare condition that historically has been associated with the presence of malignancy. Paraneoplastic phenomena in general regress with cure and in most cases with treatment of the cancer. This study was undertaken to determine whether MP regressed with cancer treatment and cure.METHODS: This was a retrospective review of a database of all patients with

INTRODUCTION: Anal squamous cell cancers are uncommon, and primary treatment is radical chemoradiotherapy. The role of radical surgery is in salvage of patients with residual and recurrent disease. The primary aim of the study is to determine how often such salvage surgery is required, while the secondary aim is to determine which features indicate salvage surgery may be required and to determine

OBJECTIVE: To compare the outcomes of laparoscopic lavage and sigmoid resection in perforated diverticulitis with purulent peritonitis.BACKGROUND: Peritonitis secondary to perforated diverticulitis has conventionally been managed by resection and stoma formation. Case series have suggested that patients can be safely managed with laparoscopic lavage, resulting in reduced mortality and stoma format

BACKGROUND: Colorectal cancer (CRC) is the third most common cancer worldwide. This study was undertaken to evaluate survival outcomes and changes of disease outcomes of CRC patients over the last decades.METHODS: A retrospective analysis of CRC patients in Christchurch was performed in four patient cohorts at 5 yearly intervals; 1993-94, 1998-99, 2004-05 and 2009. Data on cancer location, stage,

BACKGROUND: The management of diverticular disease and its complications are an increasing burden to the health system. The natural history of conservatively managed diverticular abscesses (Hinchey I and II) is poorly described and it remains open to debate whether subsequent sigmoid resection is indicated after conservative management. This observational study compares outcomes of patients treate

Background: Permanent stoma (PS) is common following treatment of anastomotic leakage (AL) after anterior resection (AR) and ways of predicting successful treatment outcome are missing.Purpose: To explore radiological variables in rectal contrast studies in their relation to end-result of PS following treatment for AL after AR.Material and Methods: The Swedish Cancer Registry (SCRCR) was explored

AIM: The Enhanced Recovery After Surgery (ERAS®) Society guidelines aim to standardize perioperative care in colorectal surgery via 25 principles. We aimed to assess the variation in uptake of these principles across an international network of colorectal units.METHOD: An online survey was circulated amongst European Society of Coloproctology members in 2019-2020. For each ERAS principle, responde

INTRODUCTION: Some evidence suggests that primary anastomosis following left sided colorectal resection in the emergency setting may be safe in selected patients, and confer favourable outcomes to permanent enterostomy. The aim of this study was to compare the major postoperative complication rate in patients undergoing end stoma vs primary anastomosis following emergency left sided colorectal res

INTRODUCTION: The optimal bowel preparation strategy to minimise the risk of anastomotic leak is yet to be determined. This study aimed to determine whether oral antibiotics combined with mechanical bowel preparation (MBP+Abx) was associated with a reduced risk of anastomotic leak when compared to mechanical bowel preparation alone (MBP) or no bowel preparation (NBP).METHODS: A pre-planned analysi

BACKGROUND: Laparoscopy has now been implemented as a standard of care for elective colonic resection around the world. During the adoption period, studies showed that conversion may be detrimental to patients, with poorer outcomes than both laparoscopic completed or planned open surgery. The primary aim of this study was to determine whether laparoscopic conversion was associated with a higher ma

INTRODUCTION: Transanal total mesorectal excision (TaTME) has rapidly emerged as a novel approach for rectal cancer surgery. Safety profiles are still emerging and more comparative data is urgently needed. This study aimed to compare indications and short-term outcomes of TaTME, open, laparoscopic, and robotic TME internationally.METHODS: A pre-planned analysis of the European Society of Coloproct

INTRODUCTION: The mainstay of management for locally advanced rectal cancer is chemoradiotherapy followed by surgical resection. Following chemoradiotherapy, a complete response may be detected clinically and radiologically (cCR) prior to surgery or pathologically after surgery (pCR). We aim to report the overall complete pathological response (pCR) rate and the reliability of detecting a cCR by c

Purpose: Hartmann's procedure is a well-established alternative in colorectal surgery when a primary anastomosis is contraindicated. However, the rectal remnant may cause complications. This study was designed to investigate the occurrence of pelvic sepsis after Hartmann's procedure and identify possible risk factors.Methods: All patients who underwent Hartmann's procedure between 2005 and 2012 we
