Scope and Safety of Paediatric Surgery in a Model III Hospital

Introduction Elective and emergency paediatric general surgery is performed in numerous hospitals but with differing exclusion and transfer thresholds. Recent national guidelines detail necessary surgical, anaesthetic and nursing resources for safe and efficient delivery of services. Methods A retrospective review of paediatric surgical admissions was performed from January 2015 to December 2016. Charts of prolonged admissions or readmissions were reviewed. Results There was a total of 2,079 surgical admissions. 575 (27.2%) were elective and 1504 (71.2%) were emergency admissions. Significantly more surgical procedures were performed in 2016 (n=546, 56% versus n=433, 44.2%). Laparoscopic appendicectomy was the most commonly performed procedure. Re-admission rates were lower in 2016 (n=9, 0.8% versus n=21, 2.2%). All complications were Clavien-Dindo Grade I or II. Discussion Paediatric general surgery can be safely and efficiently performed by staffed and resourced Model III hospitals.

Effective communication enhances the patients' endoscopy experience.

BACKGROUND: Undergoing an endoscopy is a stressful experience for patients. AIMS: To audit the endoscopy pathway to improve patient satisfaction. METHODS: A prospective survey of endoscopy patients to identify system improvements that were then implemented. RESULTS: The survey was performed before (N = 71) and after (N = 60) process improvements identified by the initial survey. Information provision and staff communication skills were identified for optimisation. Patient anxiety at home was significantly reduced (median 2 vs. 1, p < 0.01). Education of endoscopy staff significantly improved the quality of information provided before and after the procedure with regard to sedation (median 4 vs. 5, p < 0.01), discomfort (median 4 vs. 5, p < 0.01), complications (28 vs. 82 %, p < 0.01), findings (89 vs. 100 %, p < 0.01) and follow-up (73 vs. 90 %, p = 0.015). Gloucester Comfort Scores during endoscopy improved (median 1 vs. 0, p < 0.01) without increasing sedation levels. Patient feelings of invasion/trauma significantly decreased. Overall 95 % of patients were satisfied. CONCLUSION: Structured information leaflets and improved staff communication skills reduce anxiety and enhance patients' experiences. They are now standard operating procedures.

Gloveport hernioscopy.

It can be difficult to exclude occult, necrotic bowel in incarcerated herniae that reduce prior to emergent surgical exploration without resorting to further abdominal wall incisions. This case illustrates the Gloveport hernioscopy technique to identify necrotic small intestine that had spontaneously reduced in a man with a strangulated umbilical hernia. This minimally invasive technique allowed a multichannel examination of the peritoneal cavity without any further insult to the abdominal wall.

Fatal herpes simplex virus hepatitis following neoadjuvant chemoradiotherapy and anterior resection for rectal cancer.

We describe the case of a young patient who contracted fatal herpes simplex virus hepatitis following neoadjuvant chemoradiotherapy and anterior resection for rectal cancer. The rarity and non-specific presentation of this treatable disease, which masqueraded as the sequelae of postoperative sepsis, resulted in a diagnosis following death. Features that should prompt inclusion of herpes simplex virus hepatitis in the differential diagnoses are suggested and the case is a reminder of how neoadjuvant therapy may subtly alter a patient's immunocompetency.

Novel use of an air-filled breast prosthesis to allow radiotherapy to recurrent colonic cancer.

AIM: The authors present the novel and successful use of an air-filled breast prosthesis for extra pelvic exclusion of small bowel to facilitate adjuvant radiotherapy following resection of recurrent adenocarcinoma of the ascending bowel. The therapeutic use of radiotherapy in colon cancer can cause acute or chronic radiation enteropathy. Mobile small bowel can be sequestered in 'dead space' or by adhesions exposing it to adjuvant radiotherapy. A variety of pelvic partitioning methods have been described to exclude bowel from radiation fields using both native and prosthetic materials. METHOD: In this case a 68 year old presented with ascending colon adenocarcinoma invading the peritoneum and underwent en bloc peritoneal resection. Thirty-seven months later surveillance CT identified a local recurrence. Subsequent resection resulted in a large iliacus muscle defect which would sequester small bowel loops thus exposing the patient to radiation enteropathy. The lateral position of the defect precluded the use of traditional pelvic partitioning methods which would be unlikely to remain in place long enough to allow radiotherapy. A lightweight air-filled breast prosthesis (Allergan 133 FV 750 cms) secured in place with an omentoplasty was used to fill the defect. RESULTS: Following well tolerated radiotherapy the prosthesis was deflated under ultrasound guidance and removed via a 7-cm transverse incision above the right iliac crest. The patient is disease free 18 months later with no evidence of treatment related morbidity. CONCLUSION: The use of a malleable air-filled prosthesis for pelvic partitioning allows specific tailoring of the prosthesis size and shape for individual patient defects. It is also lightweight enough to be secured in place using an omentoplasty to prevent movement related prosthesis migration. In the absence of adequate omentum a mesh sling may be considered to allow fixation. In this case the anatomy of the prosthesis position allowed for its removal without the need for repeat laparotomy. Pre-operative deflation of the air-filled prosthesis under ultrasound guidance also reduces the size of the incision required for removal. This technique may be valuable to prevent collateral small bowel irradiation following resection of renal or retroperitoneal malignancy.

COX-2, VEGF and tumour angiogenesis.

Epidemiological evidence suggests a protective effective of regular NSAID use against developing cancer. Cyclooxygenase-2, a target of NSAIDs, is upregulated in many cancers and has been associated with increased VEGF production and angiogenesis. Angiogenesis is the formation of new vessels from existing vasculature and as an essential process for tumour development represents an important therapeutic target. Following an extensive review of the literature this article details the current knowledge on the role of COX-2 in tumorigenesis focusing on its relationship to angiogenesis and VEGF production by tumour cells. While COX-2 is clearly detrimental to prognosis and NSAIDs have a beneficial effect, the possibility of COX-2 independent effects being partly or wholly responsible for this benefit cannot be excluded.

Autoimmune pancreatitis.

BACKGROUND: Approximately 2 per cent of pancreatic masses resected for suspected malignancy are found instead to be a form of chronic pancreatitis defined by a characteristic lymphoplasmacytic infiltrate. This condition is now commonly classified as 'autoimmune pancreatitis'. METHODS: A literature review of autoimmune pancreatitis was performed using Medline and PubMed. The reference lists of identified articles were searched for further relevant publications. RESULTS: Patients are predominantly 55-65 years old and present with obstructive jaundice, abdominal pain and weight loss. Imaging may show a mass of malignant appearance or pancreatobiliary tree strictures precipitating surgical exploration. Raised serum levels of IgG4 and specific autoantibodies, when combined with particular radiological features and a biopsy negative for malignancy, enable a preoperative diagnosis and successful treatment with steroids. CONCLUSION: Autoimmune pancreatitis is not uncommon and steroid treatment can effect a dramatic improvement. Care is needed to ensure that pancreatic cancer is not misdiagnosed.

Rapid assessment breast clinics--evolution through audit.

This observational, cohort study aimed to examine the potential utility of Rapid Assessment Breast Clinics (RABC) beyond cancer detection at presentation. One thousand four hundred and twenty nine women were studied over an 18 month period. 154 (10.7%) had breast cancer - 87.7% of whom were seen expediently with 92.9% being diagnosed at one attendance. One hundred and forty three (10%) of those with a benign diagnosis were found by routine questioning to have significant familial risk separate to their reason for referral. Despite careful triage, considerable contamination of appointment allotment occurred with many who were correctly triaged as non-urgent being seen 'urgently'. One hundred and seventy six attendees (12.3%) had neither the symptom that triggered referral, nor breast lump, nipple discharge nor family history of breast cancer, while 283 (19.8%) had no objective clinical or radiological abnormality. Although RABC reliably categorise malignant versus non-malignant diagnoses despite cluttering by low risk women, a significant proportion of non-cancer patients still require address of future risk rather than reassurance of their present status alone.

Radiation enteropathy.

Radiation enteritis is a functional disorder of the intestine that occurs during or after a course of radiotherapy to the abdomen, pelvis or rectum. It presents in both an acute and chronic form and has sequelae that can be life threatening. As radiotherapy is now being used more than ever before in the treatment of solid organ malignancies in the abdomen and pelvis, the incidence of radiation enteropathy is likely to increase in the future. We present two patients with severe forms of this condition in order to clarify the salient issues regarding its diagnosis and, in particular, its distinction from mechanical bowel obstruction. We also review its pathophysiology, management and current preventative strategies.
