Open Minimally Invasive Parathyroidectomy Versus Minimally Invasive Video-Assisted Parathyroidectomy: A Systematic Review and Meta-Analysis

Various minimally invasive techniques exist for surgical parathyroidectomy. The aim of this study was to conduct a meta-analysis comparing two popular minimally invasive techniques: minimally invasive video-assisted parathyroidectomy (MIVAP) and open minimally invasive parathyroidectomy (OMIP). An extensive search was conducted of online databases to identify all previous studies that had compared MIVAP and OMIP. The primary outcome measures considered were visual analog scale (VAS) score 24 hours postoperatively, conversion of operation (to open), failure rate and analgesic consumption. The data from these studies was extracted and compiled into a meta-analysis. The literature search yielded 104 studies of which four were included, enrolling 903 patients in this analysis. A significant difference was found regarding rates of conversion to open parathyroidectomy between the two groups, with the OMIP group demonstrating fewer conversions (MD = 3.52, CI = (2.04-6.08), P< 0.00001). No statistically significant differences were found between the two groups when comparing postoperative VAS scores at 24 hours (MD = -1.75, CI = (-9.8-6.3), P = 0.67), consumption of analgesia (OR = 0.49, CI = 0.07-3.54, P = 0.48) or failure rates (OR = 1.81, CI = 0.58-5.72, P = 0.31). OMIP was seen to require less need to convert to open parathyroidectomy with shorter operative times, while similar complication rates and scar lengths to MIVAP. More studies are required to evaluate the superior technique for parathyroidectomy.

[Post-operative pain management in hospitals]

BACKGROUND

Relief of post-operative pain has a bearing on the patient's well-being, mobilisation and time confined to bed. The article discusses indications, contraindications and the efficacy of the various treatment modalities.

MATERIAL AND METHOD

We have examined review articles, meta-analyses and randomised controlled trials, identified through literature searches in PubMed.

RESULTS

The use of several medicines and techniques (multimodal pain treatment) is necessary to achieve a good balance between pain relief, side effects and risk. Systemic administration of paracetamol, NSAIDs, opioids and glucocorticoids is effective for post-operative pain. The same applies to epidural analgesia, peripheral nerve blocks and local anaesthetic wound infiltration. Subanaesthetic doses of ketamine have an opioid-sparing effect, but the optimal dosing regimen is uncertain. Gabapentinoids have an effect on post-operative pain, but the effect appears to vary depending on the type of operation and analgesic regimen. The effect of one analgesic will depend on which other drugs are used in multimodal pain treatment. Epidural analgesia, peripheral nerve blocks or extensive local infiltration analgesia is often necessary to relieve movement-related pain.

INTERPRETATION

Many treatment modalities are effective for post-operative pain. It is crucial that the treatment is well organised and that it includes routines for systematic pain assessment, efficacy and side effects of the pain management.

[Ambulatory surgery and anaesthesia]

BACKGROUND

Most surgical procedures in Norway are performed on an ambulatory basis. Many types of health professionals are involved and need training in how to handle these patients. The paper reviews important aspects of handling ambulatory surgical patients.

MATERIAL AND METHODS

The authors' research, clinical experience from ambulatory anaesthesiology and literature identified through a non-systematic search in Medline and EMBASE form the basis for the article.

RESULTS

With the advent of modern techniques, anaesthesia is no longer a limiting factor for whether surgery can be performed on an ambulatory basis or not. The decision to hospitalize a patient after elective surgery is based on limitations in the patient's general health, daily functioning and psychosocial status or the type of surgical procedure planned. When assessing whether surgery can be elective or not it is valuable to consider the entire treatment chain and ask the following questions: Can this patient who has undergone this procedure be expected to cope with transport and staying at home or in a hotel the same day as the operation, when escorted by an adult until the next day? - and is it safe?

INTERPRETATION

To ensure good planning and performance, it is important that the anaesthetist has access to up-to-date information on planned surgical procedures, the patient's general health, use of medication, allergies and level of daily functioning.
