The aetiology of pouchitis in patients with inflammatory bowel disease.

Restorative proctocolectomy with ileal pouch-anal anastomosis is a treatment option for patients with refractory ulcerative colitis. Pouchitis is the most common complication, representing a spectrum of diseases ranging from acute antibiotic-responsive type to chronic antibiotic-refractory. Early accurate diagnosis using a combined assessment of symptoms, endoscopy and histology is important for both treatment and prognostication.

Clozapine-Induced Refractory Colonic Pseudo-Obstruction.

The management of treatment-resistant schizophrenia (TRS) is challenging as the medications involved, often atypical antipsychotics, have a host of associated adverse effects. While complications such as agranulocytosis are well established and necessitate close hematological monitoring, the gastrointestinal effects of particular atypical antipsychotics, such as clozapine, are recognized to a lesser extent. The following case of TRS leading to chronic treatment-resistant pseudo-obstruction, eventually requiring total colectomy, highlights the considerable sequelae of clozapine on the gastrointestinal tract.

Impact of obesity on patients undergoing surgery for rectal cancer in Australia and New Zealand.

Purpose: Patients with obesity undergoing rectal cancer surgery may have an increased risk of developing complications, though evidence is inconclusive. The aim of this study was to determine the direct impact of obesity on postoperative outcomes using data from a large clinical registry.

Method: The Binational Colorectal Cancer Audit registry was used to identify patients who underwent rectal cancer surgery in Australia and New Zealand from 2007-2021.

Metastatic osteosarcoma bowel perforation secondary to chemotherapy-induced tumour necrosis.

Osteosarcoma is the most common paediatric and adolescent primary bone malignancy and is highly chemosensitive. Gastrointestinal metastases from osteosarcomas are rare. Bowel perforation secondary to chemotherapy is a potential serious complication reported in ovarian, colorectal and haematological malignancies.

Impact of preoperative smoking on patients undergoing right hemicolectomies for colon cancer.

Purpose: The tobacco epidemic is one of the biggest global public health issues impacting quality of life and surgical outcomes. Although 30% of colon cancers warrant a right hemicolectomy (RH), there is no specific data on the influence of smoking on postoperative complications following RH for cancer. The aim of this study was to determine its effect on post-surgical outcomes.

Vesicocutaneous Fistula Following Radiation and Surgery for the Treatment of Rectal Cancer.

Vesicocutaneous fistulas (VCF) are abnormal tracts formed between the bladder and the cutaneous surfaces of the body. Although rare, it has been reported following radiotherapy to the pelvic region, surgery and trauma. We present a case of a 70-year-old male who underwent neoadjuvant chemoradiotherapy for the treatment of rectal cancer metastatic to the perineum prior to definitive abdominoperineal resection (APR).

Occult Para-Psoas Hernia during Routine Endoscopic Totally Extraperitoneal Inguinal Hernia Repair.

Background And Objectives: Advantage of the total extraperitoneal (TEP) technique over open inguinal hernia repair allows for exploration of other anatomical regions in search for occult hernias (OH).

Methods: Our institutional practice is to routinely explore the obturator and femoral regions for occult hernias. In addition to this technique, we routinely expose the psoas muscle extensively to perfect mesh placement followed by fibrin glue fixation on both 'triangles of doom and pain'.

A decade review of emergency obturator hernia repairs.

Background: Obturator hernia is a rare pelvic hernia associated with a high morbidity and mortality. It most commonly occurs in elderly, multiparous females with symptoms and signs of small bowel obstruction. We present an Australian hospital network experience on emergency presentations of obturator hernias highlighting differences between clinical profile and surgical management.

How to do a combined endoscopic and tailored open extraperitoneal approach for large congenital inguinoscrotal hernia.

Large inguinoscrotal hernias require experienced and skilful laparoscopic hernia surgeons to reap the benefits of laparoscopic versus open surgery. We advocate for an alternative hybrid TEP-open technique that allows tissue extraction away from the groin area, whenever necessary, thus avoiding more painful conventional open herniorrhaphy incision.

Diagnosis and Management of Adult Omental Infarction: 10-Year Case Series.

Background: Omental infarction is a rare cause of an acute abdomen with nonspecific signs that can be easily mistaken with other more common intra-abdominal pathologies. The increased use of radiological imaging has brought this diagnosis to attention with respect to management plan. We present the experience of an Australian hospital network with the diagnosis and management of omental infarction to raise awareness of this uncommon pathology.

A Fall Worth It: Cutaneous Metastatic Deposit of a Distant Colorectal Cancer With Fistula-in-Ano.

A seeded fistula-in-ano from a synchronous colon cancer is rare. We report an unconventional case of a 70-year old male who presented with an incidental post-traumatic perianal cutaneous lump following a fall. Lesion biopsy confirmed the presence of a cutaneous malignant deposit.

Extracolonic findings (ECF) on CT colonography (CTC) in patients presenting with colorectal symptoms.

Background: Computed tomographic colonography (CTC) is now an established method for imaging the colon and rectum in the screening and symptomatic setting. Additional benefit of CTC is the ability to assess for extracolonic findings especially in patients presenting with colorectal symptoms.

Purpose: To determine prevalence of extracolonic findings (ECF) in symptomatic patients undergoing CTC and determine accuracy of CTC for exclusion of significant abdominal disease and extracolonic malignancy (ECM).
