Rectal foreign body insertion as a rare cause of persistent lumbosacral plexus injury.

Rectal foreign body insertion is a common condition in emergency surgery, which often requires surgical intervention. Here we report a clinical case of rectal foreign body insertion as a rare cause of persistent lumbosacral plexus injury. A 72-year-old man presented to the emergency department complaining of acute bilateral paraplegia with loss of sensation in both legs, as well as total urinary retention. The patient underwent abdominal computed tomography, which showed a rectal foreign body measuring 13 × 11.5 × 10 cm in the lower abdomen and pelvis. Extraluminal assistance through a median laparotomy was required after unsuccessful attempts at transanal recovery alone. After removal of the foreign body, the rectal wall and anorectal sphincter were massively dilated, with severe bruising of the rectal mucosa on proctoscopy. A protective loop-ileostomy was performed. The sacral plexus is located posteriorly in the pelvis. Physiologically, the nerves are well protected by surrounding anatomical structures. Post-traumatic lumbosacral plexus injuries with paraplegia, urinary retention and anorectal sphincter insufficiency occur quite frequently after heavy traffic accidents. Lumbosacral plexus injury as a result of rectal foreign body insertion is rare. Severe neurological deficits through rectal foreign body insertion are rare but known medical conditions. To the best of our knowledge, this is the first reported case of severe and persistent post-traumatic lumbosacral plexus injury through a rectal foreign body.

Gaining consent for carotid surgery: a simulation-based study of vascular surgeons.

AIM: Despite no formal training in consenting patients, surgeons are assumed to be competent if they are able to perform an operation. We tested this assumption for carotid endarterectomy (CEA). METHODS: Thirty-two surgeons [Group 1: junior surgical trainees--performed 0 CEA's (n=11); 2: senior vascular trainees--1-50 CEA's (n=11); 3: consultant vascular surgeons - > 50 CEA's (n=10)] consented two patients (trained actors) for a local anaesthetic CEA. The performance was assessed at post hoc video review by two independent assessors using a validated rating scale and checklist of risk factors. RESULTS: There was no difference in performance between the junior and senior trainees (1: median 91 range 64-121; 2: median 100.5 range 66-125; p=0.118 1 vs. 2 Mann-Whitney). There was a significant improvement between senior trainees and consultant surgeons (3: median 120 range 89-1 142; p=0.001 2 vs. 3). Few junior (1/11) and senior (2/11) trainees, and most (8/11) consultants, were competent. Inter-rater reliability was high (alpha=0.832). Consultant surgeons were significantly more likely to discuss cranial nerve injuries (p<0.0001 Chi-square test) as well as personal or hospital specific stroke risk (p<0.0001) than their junior counterparts. They were less likely to discuss infection (p<0.0001). CONCLUSION: Senior trainees, despite being able to perform a CEA, were not competent in consent. The majority of consultant surgeons had developed competence in consenting even though they had no formal training.
