Study type
Description of intervention(s) / exposure
Participants that meet the study exclusion inclusion criteria will be randomised into one of four study groups.

Group A - Participants will receive the combined treatment of closed drainage for 4 hours and the pulmonary recruitment maneuver.

Group B - Participants will receive the single treatment of closed drainage for 4 hours.

Group C - Participants will receive the single treatment of the pulmonary recruitment maneuver plus a sham drain.

Group D - Participants will receive the current standard of care (no treatment) plus a sham drain.

The method of entry into the patient’s abdomen will be left to the discretion of the surgeon.
The maximum number of ports allowed to complete the surgery will be four. Only one 10mm port will be allowed.

Intraabdominal pressure during the surgical procedure should not exceed 15mmHg and the maximum flow rate should not exceed 40ml/min.

Closed Drain method
The drain will be administered by the surgeon.

A 15cm Blakes drain will be inserted through one of the existing 5mm port sites at the end of the surgery if the patient is randomized to arm A or B of the study. The drain will be placed on low suction, sutured down at its proximal end and removed 4 hours later by the ward nurse.

Patient’s randomized to arm C or D of the study will have a sham drain tube placed beneath a strip of sterile gauze taped to the skin, with no intraperitoneal or subcutaneous insertion and removed 4 hours later by the ward nurse. Documentation will be provided to ward staff to ensure awareness of the presence of the sham drain tube.

Pulmonary recruitment maneuver
The pulmonary recruitment maneuver will be administered by the anaesthetist.

The pulmonary recruitment maneuver will involve a series of positive pressure ventilations after the completion of the laparoscopic procedure.

It will be restricted to a maximum of five inflations and to a positive ventilation pressure of 40 mmHg, with the patients placed in the Trendelenburg position (30º) and with the laparoscopic ports left open.

Post-operative assessment
The surgeon will note in the participant’s medical file that the Visual Analogue Scale (VAS) numerical score and 15-item Quality of Recovery questionnaire (QoR-15) are required to be completed approximately 24-36 hours after the start of the operation. The time of completion of these assessments must be clearly recorded on the assessment sheets.

A Study Coordinator will approach the participants the day after their operation to provide them with the VAS and QoR-15 for completion. The Study Coordinator will:

•Record the details of consultation, including the time, on the computer data sheet assessment (eCRF). The medical records will be used to assess adherence to the interventions.

•Book an appointment for follow-up consultation for 6 weeks’ time.

Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The allocation sequence will be implemented by using the central telephone (interactive voice response system).
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Generation of the allocation sequence will be by computer-generated random numbers.
The allocation sequence will be generated by the NHMRC Clinical Trials Centre, University of Sydney, and implemented by a telephone interactive voice response system (IVRS).
Masking / blinding

Statistical methods / analysis
All analyses will be on an “intention-to-treat” (ITT) basis and will be conducted by the DATaR Consulting (Western Australia) using STATA v14 software (StataCorp 4905 Lakeway Drive, College Station, Texas 77845 USA).
As per ITT methodology, no imputation for missing data will be performed and the number of analysed observations will be reported.

Brief summary
This study will compare four different techniques for reducing the incidence of shoulder tip pain after total laparoscopic hysterectomy. Shoulder tip pain occurs commonly after the procedure and although the exact cause is unknown, it is thought that the carbon dioxide (CO2) gas that is introduced into the abdomen to allow laparoscopic surgery to be performed safely may be the cause. We believe that by combining two techniques - closed drainage and the pulmonary recruitment maneuver - after surgery may allow CO2 gas to be removed more effectively from the abdomen and allow patients to experience less shoulder tip pain than if these techniques are used on their own or not used at all.
