Laparoscopy for bowel adhesions

Laparoscopy is keyhole surgery of the abdomen in which a camera and instruments are inserted through holes in the skin, into the abdomen to see the structures within (diagnostic laparoscopy) and to correct pathology where possible (therapeutic laparoscopy). In patients that have had previous pathology or surgery to the abdomen, adhesions can develop whereby loops of bowel can get caught up in scar tissue. If this causes an obstruction of the bowel, it can be very serious, but often people just have abdominal pain that coexists with adhesions.

Prophylactic mastectomy

Prophylactic mastectomy reduces the risk of getting breast cancer (here), but does it reduce your overall risk of dying? And what are the other risks?

Sham physical therapy

Paradoxically, it is easier to perform a sham trial in surgery, the most invasive physical act, than in physiotherapy because the patient is asleep when it is delivered. Physical therapy involves physical acts that are hard to imitate as placebo treatment, but the influence of the patient-therapist interaction makes it important to tease out any placebo effect. Researchers have, however, performed sham trials in physiotherapy.

Fixing a hole

Migraine is common, affecting millions of people worldwide. A patent foramen ovale (PFO – a ‘hole in the heart’ that lets blood cross from the right heart to the left) is common as well, present in about 30% of people. When cardiologists started surgically closing PFOs, they noticed that many patients with migraine got better. As with the discovery of any association in medicine, theories of a causal link soon followed, and doctors started treating migraine by closing the hole in the heart; before properly testing it, of course.

Placebo trials of surgery

In a recent systematic review of placebo trials of surgery (here) it was found that in half of the 53 trials found, surgery was not better than placebo treatment. And in the ones where it was better, the difference wasn’t great. This may not be big news to my readers, but this review was important because it highlighted many of the problems with surgery, namely that:
1) placebo studies are needed to determine the true effectiveness of surgical procedures, but …
2) surgery and associated devices are regulated less strictly than drugs, consequently …
3) surgery is often not subjected to placebo / sham studies, even though …
4) such studies are ethical and practical.

My right foot: predicament versus illness

My right foot hurts. It hurts in the middle, underneath, but not all the time, and only when I walk or take any weight on it, especially when I get up in the morning, when it becomes difficult to walk. It has been hurting on and off since I did an 80km trek three months ago. It could be a stress fracture, or some kind of fasciitis, soft tissue tear, fatigue, injury or degeneration, but I don't really care, because I am not going to have any tests or see any health care practitioners to get their version of a diagnosis. I'm just going to leave it alone. I am going to be a person with a predicament that I can cope with, and not a patient with an illness.

Do shoulder fractures need surgery?

Fractures that occur at the upper end of the humerus near the shoulder (called humeral neck fractures) are common. They are often treated with surgery despite a lack of supporting evidence for this, particularly in older, osteoporotic patients. Now, thanks to a recent study from the UK, it is possible that most of these fractures don’t need surgery, even in young patients. This is big news, but will this research jump the gap from research into practice and influence the decision making of the end users – the patient and their surgeon?
