Efficacy and safety of sclerotherapy with polidocanol foam in comparison with fluid sclerosant in the treatment of first-grade haemorrhoidal disease: a randomised, controlled, single-blind, multicentre trial.

Purpose: Sclerotherapy is the treatment of choice for first-grade haemorrhoidal disease. Numerous studies have shown that sclerotherapy with foamed sclerosants is more efficacious than liquid in the treatment of varicose veins. The aim of this study was to assess the efficacy and safety of polidocanol foam in comparison with liquid for haemorrhoidal disease.

Randomised clinical trial of pilonidal sinus operations performed in the prone position under spinal anaesthesia with hyperbaric bupivacaine 0.5 % versus total intravenous anaesthesia.

Purpose: The aim of this randomised clinical trial was to determine whether spinal anaesthesia (SPA) is superior to total intravenous anaesthesia (TIVA) in patients undergoing pilonidal sinus (PS) operations in the prone position.

Methods: After approval of the local ethics committee, suitable patients aged 19-49 years were randomised to SPA (7.5 mg hyperbaric bupivacaine) or TIVA (Propofol and Fentanyl).

Influence of the pre-operative time in upright sitting position and the needle type on the incidence of post-dural puncture headache (PDPH) in patients receiving a spinal saddle block for anorectal surgery.

Background: A spinal saddle block can be a safe method for anorectal surgery with a low rate of complications when performed with the right technique. A dreaded complication is the post-dural puncture headache (PDPH), which can be decreased by the use of non-cutting spinal needles. Regrettably, cutting Quincke (Q)-type needles are still widely used for economic reasons.

High incidence of post-dural puncture headache in patients with spinal saddle block induced with Quincke needles for anorectal surgery: a randomised clinical trial.

Purpose: Spinal saddle block represents nearly the ideal anaesthesia technique for anorectal surgery. Post-dural puncture headache (PDPH) is a dreaded complication but can be decreased by the use of non-cutting spinal needles to rates less than 1%. Though, cutting Quincke type needles are still widely used for economic reasons, leading to a higher rate of PDPH.

Influence of sedation on patients' perceptions and recovery in patients undergoing minor perianal procedures under spinal saddle block.

Objectives: Additional intra-operative sedation may help improve acceptability and comfort of anaesthesia in patients undergoing minor anorectal (perianal) procedures under spinal saddle block. This observational study was done to determine which patients request sedatives and to what extent sedatives affect the patients' recovery.

Subjects And Methods: During a 6-month period, 500 patients undergoing minor perianal procedures received 1.

Practicability and patients' subjective experiences of low-dose spinal anaesthesia using hyperbaric bupivacaine for transanal surgery.

Purpose: The safety, effectiveness and long lasting post-operative analgesia make spinal anaesthesia in saddle block technique an "ideal" method for transanal surgery. To improve patient satisfaction and offer reliable operation conditions to surgeons, this study quantifies practicability and patients' subjective experiences with this technique.

Methods: Within a 5-month period, 400 consecutive patients undergoing transanal surgery in saddle block technique were evaluated by a standardised questionnaire.
