An imaging and diagnostic conundrum-the adrenal haemangioma.

The adrenal haemangioma, a rare benign vascular tumour, is increasingly detected through abdominal imaging. Just over 70 surgical cases have been reported since 1955. Their potential large size and overlapping imaging features with adrenocortical carcinoma poses a diagnostic challenge. Adrenalectomy is often needed for a definitive diagnosis due to inconclusive imaging. We report the case of a 61-year-old female presenting with an incidental finding of a right-sided 9.5-cm adrenal mass on imaging. Due to the risk of adrenocortical carcinoma with inconclusive imaging findings, an open right adrenalectomy was performed. The patient was discharged after 6 days with no complications. Post-surgical histopathology confirmed a diagnosis of adrenal haemangioma with a secondary adrenal pseudocyst. The presence of an adrenal incidentaloma with discordant radiological features proves to be a diagnostic conundrum. Therefore, in the setting of contradictory radiology and concerning mass size, we recommend adrenalectomy for definitive diagnosis of an adrenal haemangioma.

Proposed clinical operative synoptic report for ileocolic resection for Crohn's disease.

BACKGROUND: Crohn's disease patients may require multiple surgeries during their lifetime. Because operative reports are not standardized, information relevant to future management may not be documented. Synoptic reports used in other fields such as histopathology have proven to be effective and allow consistent documentation of results. The aim of this study was to retrospectively review the completeness of the operative reports for ileocolic Crohn's resections (ICR) and to propose a synoptic report. METHODS: A draft synoptic operative report for ICR for Crohn's disease was presented in the IBD multidisciplinary meeting and a Delphi process used to gain consensus for inclusion in the synoptic report. Retrospective analysis of consecutive ICR from January 2010 to April 2023 was undertaken to determine the presence of the standardized criteria. RESULTS: A total of 66 ICR were performed in 63 patients during the study period. No operation reports were excluded. The examination of bowel for macroscopic disease was partially documented in 88% cases. The extent of mesenteric resection and any difficulty encountered during dissection were poorly documented. The remaining length of small and large intestines was not documented in most operative reports. The clinical sections that were compulsory entrance in the electronic operative report achieved 100% compliance. CONCLUSION: This study has demonstrated that key information was often deficient in the operative report. This may have a significant impact on the future management of Crohn's patients and affects the interpretation of research outcomes. A proposed clinical synoptic operative report is easy to use and ensures compliance.

The impact of COVID-19 on adult burns: A statewide review of epidemiology and clinical outcomes.

INTRODUCTION: The COVID-19 pandemic has significantly impacted the clinical presentations of burns and the provision of services. This study aims to describe and analyse patterns and trends in adult burns across New South Wales (NSW) and the Australian Capital Territory. METHODS: A NSW statewide retrospective review was conducted from 2017 to 2022 for adult patients with burns. A comparative analysis was performed for the COVID-19 group (2020-2022) and control group between 2017 and 2019. RESULTS: We found a total of 11,433 patients (7102 non-COVID vs 4331 COVID-19). The average age in the COVID-19 group was 1.4 years older than counterparts (40.6 vs 42.0, p < 0.001). The 18 - 25 and 36 - 45 age groups experienced significantly lower proportions of presentations, whereas, the 76-85 years experienced significantly higher proportions. There was a significantly higher proportion of pressure injuries (0.1% vs 0.4%, p < 0.001) and contact burns (17.2% vs 18.7%), but lower explosions (1.3% vs 0.2%) for the COVID-19 group compared to their counterparts. The mean TBSA% was 0.4% greater in the COVID-19 group compared to their counterparts (2.4 vs 2.8, p < 0.001). There were significantly more operating sessions (0.2 vs 0.3, p < 0.001). The mean length of stay was significantly greater by 0.8 days for the COVID-19 group compared to their counterparts (1.5 vs 2.3, p < 0.001). CONCLUSIONS: Epidemiological changes were not greatly different to previous years from the impact of COVID-19. The shift in elderly presentations and operative interventions reflects the holistic care of burns units working in a new landscape with an invigorated focus on telehealth and outpatient care.

Xanthogranulomatous cholecystitis: diagnostic complexity and review of the literature.

We report the case of a 39-year-old male presenting with acute onset vomiting and diarrhoea. Initially treated empirically for gastroenteritis, imaging later confirmed a complicated episode of cholecystitis with fistular formation and intra-abdominal cyst. Following cholecystectomy, histology confirmed a case of xanthogranulomatous cholecystitis (XGC). This paper presents a detailed summary of the condition alongside a literature review of all available episodes of XGC since 2017 with the aim of highlighting diagnostic conclusions regarding the nature of the disease and its clinical manifestations.

Breast hibernoma in a male patient: a rare case report and review of the literature.

Hibernomas are uncommon, benign, lipomatous tumours of brown fat. Although hibernomas may arise from any region where brown fat exists, common locations include thigh, shoulder, back and neck. We report a rare finding of a breast hibernoma in a 43-year-old male. The patient was managed surgically with an excision of the breast mass. This report will outline the pathology and clinical findings of breast hibernomas and review of the literature.

Necrotising Fasciitis During the COVID-19 Pandemic: An Australian Hospital Network Experience.

BACKGROUND: The clinical presentations of diseases and the provision of global healthcare services have been negatively affected by the COVID-19 pandemic. Our study aimed to determine the impact of this global pandemic on presentations of necrotising fasciitis (NF). METHODS: A retrospective study was conducted of adult patients with NF in South West Sydney Local Health District from January 2017 to October 2022. An analysis of sociodemographic and clinical outcomes was performed comparing the COVID-19 cohort (2020-2022) and the pre-COVID-19 cohort (2017-2019). RESULTS: Sixty-five patients were allocated to the COVID-19 cohort, and 81 patients were in the control cohort. The presentation to hospitals of the COVID-19 cohort was significantly delayed compared to the control cohort (6.1 vs. 3.2 days, P < 0.001). Patients of the age group of 40 years and younger experienced prolonged operative time (1.8 vs. 1.0 h, P = 0.040), higher number of operations (4.8 vs. 2.1, P = 0.008), and longer total length of stay (LoS) (31.3 vs. 10.3 days, P = 0.035) during the pandemic. The biochemical, clinical, or post-operative outcomes of two groups were not significantly different. CONCLUSION: This multi-centre study showed that the COVID-19 pandemic delayed presentations of NF but did not result in any significant overall changes in operative time, ICU admissions, LoS, and mortality rate. Patients aged less than 40 years in the COVID-19 group were likely to experience prolonged operative time, higher number of operations, and greater LoS.

Female with multiple groin pathologies: inguinal hernia containing fallopian tube, obturator hernia and subcutaneous endometrioma.

Groin lumps in females can be challenging due to unique anatomy and vast differential diagnostic pathologies. We report the case of a 39-year-old female presenting with a six-month history of painful left groin lump. Laparoscopic total extraperitoneal (TEP) hernia repair showed an incarcerated left indirect inguinal hernia sac containing part of the left fallopian tube and fimbrial cyst, a left fat-containing obturator hernia and associated with ectopic subcutaneous inguinal endometrioma. The anatomical differences in women suggest that individualized preoperative imaging modalities such as magnetic resonance imaging have a place before considering laparoscopic hernia repair, to successfully identify and synchronously treat any concomitant pathologies.

Migratory biliary stent resulting in colonic perforation: a rare complication and review of literature.

Biliary stent insertion during endoscopic retrograde cholangiopancreatography is used as a therapeutic intervention allowing flow of bile into the duodenum. In rare circumstances, distal gastrointestinal perforation can be attributed to a migrated biliary stent, with the most common site being the sigmoid colon. In these cases, surgical and/or endoscopic intervention may be required. We report a case of a 98-year-old male presenting with small bowel obstruction secondary to migrated plastic and metal biliary stents placed for acute biliary pancreatitis. Due to advanced age and high-risk multiple comorbidities, conservative management was undertaken. The patient was discharged after 5 days after ongoing pain and obstipation with palliative care services in place.

Cutibacterium acnes in breast implants: an underestimated bacterial infection and review of the literature.

The role of bacteria and breast implant illness is an emerging area of interest for surgeons and clinicians. The most common cause of surgical readmission remains post-operative infectious complications. Cutibacterium acnes is an anaerobic, gram-positive organism that is part of the normal human microbiota. In certain circumstances, it may cause chronic infections and capsular contractures in breast implant-related complications. This case series outlines patients with bilateral capsular contractures and growth of C. acnes. The patients were managed surgically with the removal of bilateral breast implants with en bloc capsulectomy and oral antibiotics without complications. This report will outline the pathology of C. acnes, association with breast implant-associated anaplastic large cell lymphoma and review of the literature.

Facial Fractures in Indigenous and Non-indigenous Populations of South Australia.

INTRODUCTION: Maxillofacial trauma in indigenous populations is complex with sociocultural factors, access to health care, and poorer general health issues that impact outcomes. Assaults and road traffic accidents are disproportionately experienced by indigenous persons compared with non-indigenous. METHODS: A retrospective review was conducted from January 2012 to January 2017 at the Women and Children's Hospital and Royal Adelaide Hospital, Adelaide. All maxillofacial fractures that attended or were referred to the unit were included in this study. The primary objective was to analyze epidemiological trends of facial fractures and clinical outcomes in the South Australian indigenous and non-indigenous populations. RESULTS: Maxillofacial fractures in indigenous persons were less than in non-indigenous (31.2 versus 38.2 y, P < 0.001) with 3.8 odds of a facial fracture. Assault was 2.9 times more likely to result in a facial fracture, falls 40.9% less likely, and sports 29.4% less likely compared with non-indigenous ( P < 0.001). Alcohol-related facial fractures had significantly higher rates [odds ratio (OR = 3.8)] compared with non-indigenous. Indigenous from most disadvantaged areas and very remote areas also had significantly higher odds of a facial fracture. Indigenous persons had higher operative rates (OR = 2.8), postoperative complications (OR = 3.1), and a 3.7-day mean difference for the length of stay (6.6 versus 2.9 d, P < 0.001). CONCLUSIONS: Indigenous people are more likely to experience facial fractures from assault resulting in mandibular fractures, whereas non-indigenous people are likely to have sport or fall-related midface fractures. Young indigenous women from outer regional and very remote areas have greater odds of facial fractures caused by assault and alcohol with higher operative rates, postoperative complications, and extended length of stay.

Patterns and characteristics of maxillofacial fractures in women.

PURPOSE: Facial trauma in women is complex with physical, psychosocial, and cultural influences impacting clinical presentations. Although multifactorial, assaults and falls are principally reported as the main causes. METHODS: A retrospective review was conducted from January 2012 to January 2017 at the Women and Children's Hospital and Royal Adelaide Hospital, Adelaide. All maxillofacial fractures in women that attended or were referred to the unit were included in this study. The primary objective was to analyse epidemiological trends of facial fractures and clinical outcomes in the South Australian female population. RESULTS: There is a bimodal distribution of facial fractures at 25-35 years and 65 + years. Indigenous females were 19.5 years younger than non-indigenous females (30.5 vs 49.9, P < 0.001). Approximately half the cohort had a fall-related facial fracture, followed by assault (26.2%), and sports (10.3%). There was a higher proportion of non-alcohol-related trauma from assaults than alcohol-related assaults (72.5% vs 27.5%, P < 0.001). Over half (58.0%) of the cohort had a midface fracture. The elderly had increased odds of 1.9 fold for facial fractures in winter, largely from falls, compared to younger women. Associated injuries were present in almost half the elderly women with 2.6 times the risk compared to younger women. Younger women had higher incidences of surgical intervention (52.6% vs 14.3%, P < 0.05). CONCLUSIONS: Young women disproportionately experience larger incidences of non-alcohol-related assaults requiring operative intervention of the mandible, whereas elderly women principally suffer fall-related facial fractures with higher rates of associated injuries.

Outcomes following anastomotic leak from rectal resections, including bowel function and quality of life.

PURPOSE: Anastomotic leak (AL) is an uncommon but potentially devastating complication after rectal resection. We aim to provide an updated assessment of bowel function and quality of life after AL, as well as associated short- and long-term outcomes. METHODS: A retrospective audit of all rectal resections performed at a colorectal unit and associated private hospitals over the past 10 years was performed. Relevant demographic, operative, and histopathological data were collected. A prospective survey was performed regarding patients' quality of life and fecal continence. These patients were matched with nonAL patients who completed the same survey. RESULTS: One hundred patients (out of 1,394 resections) were included. AL was contained in 66.0%, not contained in 10.0%, and only anastomotic stricture in 24.0%. Management was antibiotics only in 39.0%, percutaneous drainage in 9.0%, operative abdominal drainage in 19.0%, transrectal drainage in 6.0%, combination of percutaneous drainage and transrectal drainage in 2.0%, and combination abdominal/transrectal drainage in 1.0%. The 1-year stoma rate was 15.0%. Overall, mean Fecal Incontinence Severity Instrument scores were higher for AL patients than their matched counterparts (8.06±10.5 vs. 2.92±4.92, P=0.002). Patients with an AL had a mean EuroQol visual analogue scale (EQ-VAS) of 76.23±19.85; this was lower than the matched mean EQ-VAS for non-AL patients of 81.64±18.07, although not statistically significant (P=0.180). CONCLUSION: The majority of AL patients in this study were managed with antibiotics only. AL was associated with higher fecal incontinence scores in the long-term; however, this did not equate to lower quality of life scores.

Inguinal bladder hernia: differentials for a male groin mass.

Inguinal bladder hernia (IBH) is an uncommon occurrence in males with a groin mass. It may be present with lower urinary tract symptoms but is often asymptomatic, making it a diagnostic challenge. IBH is frequently an incidental finding during surgery, which increases the risk of iatrogenic injury of the bladder. This report examines the case of a 77-year-old male who experienced a painful, reducible right-sided groin mass with acute urinary retention. Investigations conducted through computed tomography exhibited a right indirect inguinal hernia containing omental fat and a portion of the urinary bladder. The patient underwent a right open herniorrhaphy with mesh repair. This report presents a systematic approach to differential diagnoses for a male groin mass and its relationship to IBH.

Eosinophilic mastitis: a rare benign inflammatory condition and review of the literature.

We report the case of a 53-year-old nulliparous female presenting with a 9-month history of recurrent mastitis and a retro-areolar lesion. Histological assessment showed an inflammatory infiltrate predominantly composed of eosinophils without evidence of malignant changes. The patient was diagnosed with eosinophilic mastitis and commenced on a course of oral steroids with good effect. This case will outline the pathology, clinical manifestations and diagnosis of eosinophilic mastitis alongside a review of the literature.

Loop and drain technique for prevention of surgical site infection in upper gastrointestinal surgery.

INTRODUCTION: Hepatobiliary and pancreatic surgery is frequently complicated by surgical site infections (SSI) with significant postoperative morbidity and mortality rates contributing to the economic burden on healthcare. Advancements in operative techniques to prevent SSI are gaining traction in clinical practice. This study compares the effectiveness of the 'loop and drain technique (LDT)', a combination method utilizing a continuous subcutaneous vessel loop and subcuticular suture for surgical wound closure in patients undergoing upper gastrointestinal surgery at a Metropolitan Hospital in Sydney. METHODS: A retrospective review of patients who underwent an upper gastrointestinal procedure was conducted at Bankstown-Lidcombe hospital between 2017 and 2019. There were 77 patients in the LDT group and 123 patients included in the control group. The primary outcome assessed was the rate of SSI. Secondary outcomes included length of stay (LOS) and drainage of surgical site infections. RESULT: Two hundred adult patients were treated for an upper gastrointestinal procedure. The most common operation was a Whipple procedure (35.0%). The rate of SSI was 12.5% with all these patients receiving intravenous antibiotics. The LDT cohort had a significantly lower rate of SSI compared to their counterparts (3.9% vs. 17.9%, P = 0.004). CONCLUSION: The LDT method is associated with a decreased incidence of SSI and should be considered as a cost-effective operative technique to improve patient outcomes after upper gastrointestinal surgery.

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. METHODS: Patients who underwent elective RH for colon cancer between 2016 and 2019 were identified from the ACS-NSQIP database. Propensity score matching (PSM) was used with a maximum absolute difference of 0.05 between propensity scores. Primary outcome was to assess the 30-day complication risk profile between smokers and non-smokers. Secondary outcomes included smoking impact on wound and major medico-surgical complication rates, as well as risk of anastomotic leak (AL) using multivariable logistic regression models. RESULTS: Following PSM, 5652 patients underwent RH for colon cancer with 1,884 (33.3%) identified as smokers. Smokers demonstrated a higher rate of organ space infection (4.1% vs 3.1%, p = 0.034), unplanned return to theatre (4.8% vs 3.7%, p = 0.045) and risk of AL (3.5% vs 2.1%, p = 0.005). Smoking was found to be an independent risk factor for wound complications (OR 1.32, 95% CI 1.03-1.71, p = 0.032), primary pulmonary complications (OR 1.50, 95% CI 1.06-2.13, p = 0.024) and AL (OR 1.66, 95% CI 1.19-2.31, p = 0.003). CONCLUSION: Smokers have increased risk of developing major post-operative complications compared to non-smokers. Clinicians and surgeons must inform smokers of these surgical risks and potential benefit of smoking cessation prior to undergoing major colonic resection.

A diagnostic workup and laparoscopic approach for median arcuate ligament syndrome.

BACKGROUND: Median arcuate ligament syndrome (MALS) is a rare disorder characterized by the compression of the coeliac trunk and plexus by fibrous arches of the median ligament. It commonly occurs in young women with postprandial epigastric pain, weight loss and nausea. We present a single surgeon experience on the diagnostic approach and management of MALS with a focus on laparoscopic surgery. METHODS: A retrospective review of adult patients diagnosed with MALS during a 10-year period (2011-2021) was conducted at Bankstown-Lidcombe hospital in New South Wales, Australia. RESULTS: MALS was diagnosed in six patients (mean 46 years, range: 27-74 years old), all confirmed on mesenteric duplex ultrasound and computed tomography angiography. The most common presentations were women with post-prandial pain, exercise induced pain and an average weight loss of 14.5 kg. The median interval from onset of symptoms to surgical referral was 10.5 months. The average BMI was 24.1 kg/m2 and most had a grade III American Society of Anaesthesiologist physical status. All patients underwent laparoscopic release of median arcuate ligament with one patient requiring endovascular stenting. The mean operative time was 119 minutes with two minor post-operative complications, but no mortalities. The median hospital length of stay was 3.5 days with a median follow up of 3.5 years. CONCLUSION: Laparoscopic median arcuate ligament release with endovascular support for selected cases provides sound clinical resolution of symptoms and long-term results.

The impact of COVID-19 on delayed presentations of necrotising fasciitis.

The purpose of this study was to determine the impact of coronavirus disease 2019 (COVID-19) on the delayed presentation of necrotising fasciitis (NF). A retrospective study was conducted of adult patients (≥16 years old) diagnosed with NF at a hospital from 2017 to 2020. A quantitative comparative analysis for the COVID-19 group and control group between 2017 and 2019. Structured interviews were conducted to examine the impact of COVID-19 on patients. There were 6 patients in the COVID-19 group and 10 patients in the control group. The COVID-19 group had a longer mean onset of symptoms till hospital presentation of 4.1 days and a longer mean operative time. The COVID-19 group was more likely to be admitted to intensive care unit. Three patients in the COVID-19 group did not survive compared to survival in the counterparts. Participant responses indicated the COVID-19 pandemic did not prevent them from presenting to ED.

A comparative analysis of associated injuries in the elderly and youth for facial fractures.

INTRODUCTION: High-velocity and high-impact forces can yield life-threatening injuries that are not only limited to the face but can involve other regions of the body. Associated injuries are more frequent in the elderly impacting management and outcomes. The primary objective was to study the association between associated injuries and age groups by identifying epidemiological trends and differences among the elderly and younger population. METHODS: A retrospective review was conducted from January 2012 to January 2017 at the Royal Adelaide Hospital, Adelaide. A comparative analysis for elderly and younger controls was assessed for associated injuries, etiology, management, and length of stay. RESULTS: There were 355 elderly and 1884 younger controls for the study. There were differences between gender, alcohol, socioeconomic status, type of facial fracture, mechanism of injury, and associated injuries (p<0.05). The elderly were 3.6 times more likely to have an associated injury compared to the younger cohort (p<0.05). Total limb injuries were 2.2 times more likely in the elderly compared to the younger cohort, and neurological related injuries were 2.7 times more likely (p<0.05). Neurological injuries were most frequent in fall-related injuries, limb injuries in RTA; and soft-tissue injuries for assault, sport, animal, and work (p<0.001). The elderly had longer hospital stays as compared with younger controls (p<0.05). CONCLUSIONS: Associated injuries are more frequent in the elderly and impact other bodily systems leading to a longer length of stay. In the assessment and management of facial trauma, anatomical and disciplinary boundaries may cross requiring interdisciplinary care.
