The aim of the present study is to develop, implement a planning tool for rare and complex visceral surgical procedures. With the successful implementation of the planning tool the study will contribute to the improvement of intraoperative processes and their outcome in low volume surgery and offer an alternative to continued centralization of surgical care especially in case of geographical or disease specific premises.
The quality of the intraoperative process is still a blind spot, when it comes to clinical surgical research in the operating room. In contrast to pre and postop process optimization with tools like the World Health Organization (WHO) checklist or the Enhanced Recovery after Surgery (ERAS) protocol intraoperative processes tend to be poorly defined especially in rare and complex visceral surgery (e.g. esophageal, pancreatic rectal resection, sarcoma surgery, revisional bariatric surgery). This leads to delay, increased stress of the operating team and increased intraoperative mistakes and eventually increased complication rates. From previous investigations we know that step by step planning and briefing of the entire OR Team can reduce operative interruptions. With the development of a dedicated planning tool which allows to create and distribute step by step protocols for rare and complex visceral surgical procedures to the entire OR Team we hope to decrease delays and reduce OR time variance. Objective: Development and implementation of a planning tool for rare and complex visceral surgical procedures. Outcomes: Primary outcome: (delay/variability) operative times as defined as time from skin incision to skin closure Secondary outcomes: * Costs * Influence of preoperative augmented planning on degree of and quality of teaching * Level of stress of each operating team member * Number of intraoperative mistakes * Number and severity of intraoperative and postoperative complications

The study investigates the impact of augmented preoperative planning on OR time variance in complex and rare visceral surgical procedures.
University Hospital Basel/Dep. of General and Visceral Surgery
Basel, Canton of Basel-City, Switzerland
delay/variability of operative time
The primary outcome is the (delay/variability) of operative time as defined as time from skin incision to skin closure that will be recorded with the hospital OR planning program (Ismed Protect Data) and compared to preoperatively planned times.
Time frame: 1 year, measured after every operation
Costs
Costs will be calculated as intraoperative delay compared to preoperative planning in minutes multiplied with the OR minute costs of the institution in addition to the average salaries per minute of the involved surgical staff. OR minute costs will be calculated by dividing the OR and anesthesia cost units through the overall operative time in the institution. The OR cost unit includes the personnel expenses for operating nurses and other staff (including cleaner and others) as well as maintenance costs (single use equipment, depreciation on buildings and running expenses like water and electricity etc. The cost unit anesthesia includes all expenses for personnel (doctors and nurses), depreciation for respirators and other devices as well as expandable materials.
Time frame: 1 year, calculated after every case once patient is dismissed
Level of stress
Level of stress of each operating team member will be assessed directly postoperatively with a Visual Analogue Scale (VAS) report (operated on an ipad for data collection). The VAS Scale will consist of a 0 (no stress) to 7 (maximum stress) item scale.
Time frame: 1 year, measured during every operation
Number of intraoperative mistakes
Number of intraoperative mistakes will be recorded with a pedal button operated by the first assistant on the demand of the lead surgeon.
Time frame: 1 year, measured during every operation and compiled after the operation is finished
Number and severity of intraoperative complications
This platform is for informational purposes only and does not constitute medical advice. Always consult a qualified healthcare professional.
Number and severity of intraoperative complications will be assessed directly postoperatively by the lead surgeon and or first assistant, audio video records are available for review purposes. Postoperative complications will be recorded after discharge on the basis of discharge summary and proceeding notes of the patient.
Time frame: 1 year, measured during every operation and compiled after the operation
