Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Use of vault drain during vaginal hysterectomy. If the patient was randomised to 'drain' group, a non-suction drain was inserted in the vault at the time of hysterectomy. The drain was removed postoperatively at the discretion of the operating surgeon.
Duration of vault closure with drain: 10-15 minutes
Intervention code [1] 264211 0
Treatment: Devices
Comparator / control treatment
Standard vault closure without use of drains. Standard vault closure involves non closure of peritoneum and intermittent sutures to the vagina
Duration of standard vault closure: 10-15 minutes
Control group
Active

Outcomes
Primary outcome [1] 262321 0
reduction in postoperative febrile morbidity.
The postoperative care was according to standard hospital policy where temperature is recorded in the nursing observation chart every 4 hours. This observation was recorded from patient notes at the time of data collection
Timepoint [1] 262321 0
one or more episode of temperature of 37.5 degrees C
Secondary outcome [1] 273540 0
Hospital readmission rate
Timepoint [1] 273540 0
number of repeat inpatient admissions after discharge within 3 months of surgery
Secondary outcome [2] 273541 0
length of stay
Timepoint [2] 273541 0
calculated from date of surgery to date of discharge from patient notes

Minimum age
18 Years
Maximum age
No limit
Gender
Females
Can healthy volunteers participate?
No
Key exclusion criteria
patients in whom the hysterectomy was performed for malignant disease and also cases where it was felt by the operating surgeon that the insertion of a surgical drain to the vault would be clinically indicated.

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomisation (‘drain’ or ‘no drain’) was carried out using a sealed envelope technique. Randomisation envelopes were prepared at the beginning of the study. Envelopes were double sealed to prevent bias. The randomisation envelope was opened on surgeon’s request at the time of closure of the vaginal vault.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
350 envelopes were prepared, numbered and sealed at the beginning of study. After consent for recruitment 1 envelope was included in the noted by simple randomisation
Masking / blinding

Summary
Brief summary
Vaginal Hysterectomy (VH) is one of the most commonly performed gynaecological opaerations and is associated with a significant risk of vault hematomas (25%-40%). Hematoma represents the most common peri-operative complication following VH and is significantly associated with febrile morbidity, post-operative haemoglobin drop, need for blood transfusion, re-admission to hospital and length of hospital stay
Prophylactic measures to reduce hematoma formation such as use of vault drainage may help to reduce the post-operative complications and morbidity of VH. The role of drains in abdominal surgery is well recognised and clinicians have been debating if this can be applied to VH. However no formal evaluation of routine drain insertion at VH has ever been performed. The aim of our study was to evaluate the efficacy of vault drains in reducing the risk of early post-operative morbidity following VH for benign gynaecological conditions.
