Ergonomics in handheld and robot-assisted camera control: a randomized controlled trial.

BACKGROUND: Laparoscopic surgery potentially increases the physical burden to operating theater personnel and can cause physical discomfort. This study aims to evaluate if a robotic camera holder (AutoLap™ system) can improve ergonomics for the surgeon and the camera assistant during laparoscopic procedures. METHODS: A total of thirty cases were included and randomized (15 AutoLap™, 15 control). Five types of surgery were included: right hemicolectomy, fundoplication, sigmoid resection, rectopexy, and low anterior resection. The posture of the surgeon and assistant was photographed during predefined steps of the procedure. MATLAB was used to calculate angles relevant for the RULA score. The RULA score is a validated method to evaluate body posture, force and repetition of the upper extremities. Two investigators assessed the RULA score independently. Three subjective questionnaires (SMEQ, NASA TLX, and LED) were used to assess mental and physical discomfort. RESULTS: No differences in patient characteristics were observed. Sixteen fundoplications, seven right hemicolectomies, five sigmoid resections, one rectopexy, and one low anterior resection were included. The mean RULA score of the surgeon was comparable in both groups, 2.58 (AutoLap™) versus 2.72 (control). The mean RULA score of the assistant was significantly different in both groups, with 2.55 (AutoLap™) versus 3.70 (control) (p = 0.001). The inter-observer variability (ICC) was excellent with 0.93 (surgeon) and 0.97 (assistant). The questionnaires showed a significant difference in physical discomfort for the assistant. The LED and SMEQ score were significantly lower in the robotic group. The NASA TLX demonstrated a significant reduction in scores in all domains when using robotics with the exception of the mental domain. CONCLUSION: Use of the AutoLap™ system shows improvement in ergonomics and posture of the first assistant, and ergonomics of the surgeon are not affected. Furthermore, the subjective work load is significantly reduced by using a robotic camera holder.

[Acute abdominal pain caused by neuroborreliosis]. / Acute buikpijn bij neuroborreliose.

BACKGROUND: Lyme disease is a multisystem disease which can present itself in several ways. When the nervous system is involved, it is called Lyme neuroborreliosis. Both central and peripheral nervous systems can be affected. CASE DESCRIPTION: A 39-year-old man visited the emergency department multiple times with severe abdominal-pain attacks with motoric unrest. Extensive diagnostic work-up was done, which was initially inconclusive. Lyme neuroborreliosis was suspected when he developed a facial-nerve palsy during admission; the abdominal pain was thought to be caused by thoracic radiculoneuropathy. Serologic testing for antibodies against Borrelia burgdorferi was positive, confirming the diagnosis. The patient was treated with intravenous ceftriaxone. CONCLUSION: This case shows abdominal pain being caused by radiculoneuropathy at thoracic level, an uncommon presentation of Lyme neuroborreliosis. Often, this diagnosis is only made when neurological paralysis occurs. Information regarding skin lesions or a recent tick bite can lead to earlier recognition of the diagnosis.

Portal venous air in an adult patient with obstructive small bowel volvulus.

BACKGROUND: Diagnosis of small bowel volvulus is frequently delayed often resulting in bowel ischaemia and infarction and impairing clinical outcome. Instant and correct diagnosis and subsequent adequate surgery may improve the outcome. METHODS: We describe a 19-year-old female with small bowel obstruction due to volvulus in whom the diagnosis was suspected based on the finding of air in the bowel wall and in the portal vein on a plain abdominal radiograph. CONCLUSIONS: Air, present in the portal vein and bowel wall on a plain abdominal X-ray, suggests bowel ischaemia or necrosis and that the need for laparotomy is urgent.
