Recto-anal intussusception is common in patients undergoing selective evacuation proctography for investigation of faecal incontinence. The role of recto-anal intussusception in the multifactorial aetiology of faecal incontinence has been largely overlooked. Evacuation proctography should be considered as part of routine work-up of patients with faecal incontinence.
The purpose of this study was to directly compare CT with fluoroscopy for the diagnosis of occult anastomotic leak following oesophagectomy. Patients undergoing oesophagectomy and gastric conduit formation for the treatment of oesophageal cancer were eligible for inclusion. Imaging was performed 6-8 days post-operatively. Patients underwent multislice CT examination of the chest and abdomen with a bolus of oral contrast, followed by fluoroscopic water-soluble contrast swallow (with subsequent use of barium if this was normal). The studies were reviewed by a consultant radiologist, who was blinded to the results of the other modality. Images were reported as showing "no leak", "possible leak" or "definite leak". The presence of mediastinal gas or fluid or extraluminal contrast at CT was recorded. The clinical outcome after reinstituition of oral intake was used as a reference standard. Patient preference for modality was recorded. 52 patients were recruited. Four were found to have leak on CT and fluoroscopy. 11 had possible leak at CT, but normal fluoroscopy: 2 of these had a leak confirmed later, whereas 9 had no leak. 37 had normal CT and fluoroscopy findings, and remained clinically well. The sensitivity, specificity, positive and negative predictive values were 100%, 80%, 40% and 100%, respectively, for CT, and 67%, 100%, 100% and 96%, respectively, for fluoroscopy. The positive predictive value of mediastinal air, air/fluid and extraluminal contrast were 25%, 75% and 50%, respectively. 35 patients found CT more tolerable. In conclusion, CT was better tolerated and more sensitive but less specific than fluoroscopy for detecting occult anastomotic leak.
Primary yolk sac tumour of the liver is exceedingly rare. A 28 year old woman presented with a cystic liver mass and a markedly raised serum a-fetoprotein concentration. She underwent a partial hepatectomy for a suspected hepatocellular carcinoma but histological examination of the tumour revealed the classical morphological and immunohistochemical features of a yolk sac tumour. There was no evidence of an extrahepatic primary source. Review of this case, together with the six previously reported adult cases of primary yolk sac tumours of the liver, revealed several features of the tumour that may aid differentiation from hepatocellular carcinoma, with potential therapeutic implications.

Naltrexone is a long acting opioid receptor antagonist used in controlled opioid withdrawal drug programmes. When taken by an opioid dependent patient an acute withdrawal reaction will be precipitated. The case is presented where a known opioid drug misuser inadvertently ingested naltrexone in conjunction with heroin resulting in severe agitation, requiring heavy sedation followed by general anaesthesia to enable investigation and management of his clinical condition. N altrexone is a long acting opioid receptor antagonist used in drug rehabilitation programmes to maintain opioid abstinence. However, when consumed in conjunction with an opioid substance, prolonged opioid withdrawal will be precipitated resulting in unpredictable and life threatening medical consequences. We present a case where a known drug misuser consumed naltrexone in conjunction with heroin. CASE REPORTA 39 year old man presented to the accident and emergency department having taken up to three, 50 mg tablets of naltrexone and having smoked an unknown quantity of heroin. He was known to be an injecting drug user and to suffer from epilepsy. No other recreational drugs, alcohol, or prescribed medications were known to have been consumed. On arrival he was extremely agitated being restrained by four police officers. He was confused, sweating, with episodes of profuse projectile diarrhoea and vomiting. Glasgow Coma Scale was 12 (spontaneous eye opening, localising to pain, and using inappropriate speech). Pupils were dilated but reactive to light. Heart rate was regular at 180 beats/minute and respiratory rate 40 breaths/minute. Blood pressure, oxygen saturation, blood glucose, and temperature were normal. There was no evidence of head injury and no history of seizure. Urea, electrolytes, full blood count, and arterial blood gas measurements were normal. Initial attempts at sedation using a combination of titrated intravenous midazolam and droperidol were unsuccessful. After receiving a total of 20 mg midazolam and 15 mg droperidol he continued to be confused, agitated, and increasingly violent. An urgent CT head scan was arranged to exclude any intracranial pathology. To expedite this he was anaesthetised and ventilated. Rapid sequence induction of anaesthesia was carried out using 200 mg propofol, and 100 mg suxamethonium. Anaesthesia was maintained with a propofol infusion and incremental paralysis with atracurium.CT of his brain was normal. A lumbar puncture was performed while the patient was still anaesthetised. This showed no abnormality. The patient was extubated four hours after induction and transferred to the medical high dependency unit for observation. Further episodes of agitation occurred overnight requiring additional sedation with intravenous midazolam. The following morning he took his own discharge. Retrospectively urine toxicology screen confirmed the presence of cannabinoids, benzodiazepines, and opioids.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
