INTRODUCTION
 
Ovarian torsion is the twisting of the ovary on its vascular support is the fifth most common gynecologic surgical emergency.1 The condition is more common in premenarcheal females (children or premenarcheal adolescents) constitute up to 15–50 % of adnexal torsion cases.2 The association of an ovarian cyst is a common finding in twisted ovaries, the size of the cyst is usually moderate (i.e. around 5 cm).3.4.5.6  Diagnosis is basically clinical, however, pelvic imaging, primarily by transvaginal ultrasound (TVUS) and Doppler evaluation of ovarian blood flow, confirms the diagnosis and excludes similar conditions.7,8
The gold standard to treat ovary torsion is surgery (laparoscopy and laparotomy.9 An ovarian cystectomy is often performed for a benign ovarian mass. If malignancy is highly suspected, a salpingo-oophorectomy is needed. According to many observational studies, detorsion is associated with preserved ovarian function. 10,11,12,13 
The risk of recurrence after detorsion, but the incidence and causes are unknown. 14,15,16,17 One method is suppression of ovarian cysts by oral contraceptives.18,19 Another method is an oophoropexy by plication of uteroovarian ligament 20,21
 
PRE-OPERATIVE PREPARATION:
 
1. Patient to be under General anesthetized
2. Patient return plate should be attached to the thigh.
3. Abdomen and perineum to be painted and draped
4. The surgeon has to be on the patient’s left side, an assistant on the right side and 2nd assistant if needed in between patients legs for uterine manipulation
5. Monitor to be placed 15 degrees below the visual axis of the surgeon on the opposite side. 
6. All the equipment placed on the opposite side of the surgeon
7. Camera, light source, insufflator, and electrosurgical unit to be plugged into their respective equipment and all cables tied over upper drape using a gauze and towel clip.
8. Telescope with a camera attached to the light source.
9. Laparoscopic mode to be “on “on the camera cable attachment instrument
10. White balancing and focussing of camera done by placing the camera at a focal length of 10cm from gauze piece.

OPERATIVE STEPS PROPER:

PNEUMOPERITONEUM
1. Over inferior crease of the umbilicus, place 2 Allis tissue holding forceps on either side and give 2mm stab incision with No.11 blade.
2. Dilate rectus muscle until rectus sheath with mosquito forceps 
3. Check Veress Needle of 12 cm for its spring action and patency
4. Lift up the abdominal wall at the umbilicus and assess its full thickness,
5. Veress Needle is held like a dart the thickness of the abdominal wall from its distal end.
6. Insertion of veress needle through the incision site in a manner that the veress needle makes an angle of 90’ with the abdominal wall and an angle of 45’ with the body of the patient, pointing towards the anus.
7. Insertion is achieved with two audible clicks; first of the Rectus Sheath and second of the
Peritoneum
8. Release the Allis forceps from the Abdominal wall
9. Hold the Veress Needle at an angle of 45’ making sure that no further length of the needle is advanced.
10. Confirm the intraperitoneal placement of the veress needle by aspiration test, irrigation test and hanging drop test.
11. Ensure that the Gas tubing is attached to the Insufflator and the Insufflator is switched ON. This will remove air from the Gas tubing and fill the gas tubing till its tip with CO2 gas.
12. Confirm Pre-Set Pressure to 15mmHg on the Insufflator and Attach the gas tubing to the veress needle and start the flow of CO2 gas at 1 liter per minute
13. Confirm obliteration of liver dullness and generalized distension of abdominal wall
14. Keep watch on patient’s vital parameters and EtCO2 readings during insufflation.
15. The total amount of gas and actual pressure should rise in a linear fashion.
16. When actual pressure has reached pre-set pressure and amount of gas used might vary between 1.5 to 6 liters for an averagely build young patient
17. Once the pressure reaches the pre-set pressure, remove the veress needle and use size 11 blade to make skin incision to fit a 10mm port. This can be prechecked by placing a 10mm port on the skin for estimation of incision size
 
PORT PLACEMENT
 
1. Insert the 10mm cannula with trocar by oscillatory screwing motion, the direction being
perpendicular till give way sensation is perceived and then change the direction towards the pelvis. Once you are in, the trocar should be removed and the telescope should be inserted to confirm the intraperitoneal placement
2. Connect the insufflator to the optical port and switch on the gas.
3. To begin with, an overview inspection of the entire abdomen must be done and noted.
4. Then reach out to the target organ (ovary of affected side), just about to touch it with the tip of the telescope, and trans-illuminate the anterior abdominal wall to delineate the site of the target.
5. Use the baseball diamond concept to mark the position of the additional 5 mm ports.
6. Make 15 to 30 degree Trendelenburg tilt aids in moving the bowel to the upper abdomen.
7. The surgeon must use transillumination to avoid any vessel injuries in prospective port sites. Use the size 11 blade to make small incisions to fit the 5mm ports at the pre-marked sites as per Baseball diamond concept.
8. Based on the baseball diamond concept, 2 ipsilateral 5mm secondary ports made. 1stport is 7.5cm from primary port and 2ndport, 7.5cm from 1stport along the 18 cm arc.
9. Insert both the 5mm ports under direct vision and using principles same as that used for the primary port to avoid inadvertent visceral and vascular injuries.
10. These ports have to be placed such that the manipulation angle is 60degrees, elevation angle is 30 degrees and azimuth angle from 30 degrees to a maximum of 60 degrees as they are ipsilateral ports
 
 
SURGICAL STEPS:
 
SALPINGOOOPHORECTOMY
 
1. The uterine manipulator can be used to lift up the uterus for proper visualization.
2. Grasp the ovary which has undergone torsion with an atraumatic grasper and with tritome puncture the cyst and aspire the contents.
3. Undo the torsion with the help of 2 graspers and wait for 3-5 minutes for the blood supply to return.
4. If the ovarian tissue has become gangrenous and has to be removed and so proceed with salpingooopharectomy with coagulate and cut infundibulo pelvicum ligament
5. Coagulate and cut ovarian ligament mesovarium, fallopian tube
6. Coagulate and cut mesosalpinx 3cm lateral to the uterus
 
OOPHOROPEXY
 
1. Oophoropexy  by suturing continues  and tightening the proximal to the distal end of the ovarii proprium ligament to prevent further torsion in the future
2. Take it out the cyst with endobag / take it out to the posterior fornix posterior wall vaginal with colpotomy 
3. Clean the peritoneal cavity with suction irrigation.
4. Keep watch on ETCO2 level during surgery
5. Deflate the abdomen, remove the ancillary port under the vision and the primary port removed along with trocar.
6. Close 10mm port with veress needle or port closure after desuffation
7. Extubate patient and shift patient to recovery room

Elaboration of Steps:

How to Perform and Implement Task Analysis of Laparoscopic and Robotic Procedures

Task analysis is a critical component of any complex surgical procedure, including laparoscopic and robotic surgeries. It involves breaking down the procedure into its constituent tasks, identifying the steps, skills, and cognitive processes required. Task analysis not only enhances the understanding of these intricate surgeries but also serves as a foundation for training, skill assessment, and continuous improvement in healthcare. In this essay, we will delve into how to conduct and implement task analysis for laparoscopic and robotic procedures.

Task Analysis of Laparoscopic Surgery

Understanding the Significance of Task Analysis

Before we explore the procedure for task analysis, it's essential to recognize why it is of paramount importance in the realm of surgery, particularly for laparoscopic and robotic procedures.

1. Enhanced Learning and Training: Task analysis helps in developing structured training programs. It breaks down complex procedures into manageable components, making it easier for trainees to learn and practice each step methodically.

2. Skill Assessment: By understanding the tasks and sub-tasks involved, it becomes possible to assess the competence of surgeons and surgical teams. This is crucial for ensuring patient safety and quality care.

3. Workflow Optimization: Task analysis can reveal inefficiencies in surgical workflows. Identifying these bottlenecks allows for process improvements, potentially reducing surgical times and enhancing outcomes.

4. Error Reduction: Recognizing potential points of error is vital for preventing surgical complications. Task analysis can highlight critical steps where errors are more likely to occur, leading to proactive measures to mitigate risks.

Procedure for Task Analysis of Laparoscopic and Robotic Procedures:

Task analysis for laparoscopic and robotic procedures involves several steps:

Step 1: Define the Surgical Procedure

Begin by clearly defining the surgical procedure you wish to analyze. Whether it's a laparoscopic cholecystectomy or a robotic prostatectomy, having a specific procedure in mind is essential.

Step 2: Gather Expert Input

Engage experts in the field, including experienced surgeons, nurses, and other surgical team members. Their input is invaluable in identifying and detailing the tasks involved.

Step 3: Identify the Tasks and Sub-Tasks

Break down the surgical procedure into tasks and sub-tasks. For instance, in a laparoscopic cholecystectomy, tasks could include trocar placement, camera insertion, gallbladder dissection, and suturing. Sub-tasks under "trocar placement" might involve choosing trocar sizes, making incisions, and inserting trocars.

Step 4: Sequence the Tasks

Establish the chronological order of tasks. Determine which tasks are dependent on others and identify any parallel processes. Sequencing tasks is essential for understanding the flow of the procedure.

Step 5: Define Task Goals and Objectives

For each task and sub-task, define the goals and objectives. What should be achieved in each step? For instance, in gallbladder dissection, the goal might be to safely detach the gallbladder from the liver while preserving nearby structures.

Step 6: Skill and Equipment Requirements

Specify the skills and equipment required for each task. Consider the level of expertise needed, such as basic laparoscopic skills or advanced robotic manipulation. Document the instruments and technology involved.

Step 7: Cognitive Processes

Identify the cognitive processes involved, such as decision-making, spatial orientation, and problem-solving. Understanding the mental aspects of surgery is critical for training and error prevention.

Step 8: Consider Variations and Complications

Acknowledge potential variations in the procedure and anticipate complications. How would the surgical team adapt if unexpected issues arise? Task analysis should encompass both the standard procedure and potential deviations.

Step 9: Develop Training and Assessment Tools

Use the task analysis results to create structured training modules. These modules should align with the identified tasks, objectives, and skill requirements. Additionally, design assessment tools to evaluate the competence of trainees and surgical teams.

Step 10: Continuous Improvement

Task analysis is not a one-time endeavor. Regularly revisit the analysis to incorporate new techniques, technology, and best practices. Continuous improvement is vital for staying at the forefront of surgical care.

Implementing Task Analysis Results:

Once task analysis is complete, it's crucial to implement the findings effectively:

1. Training Programs: Develop and deliver training programs based on the task analysis. These programs should encompass both simulation-based training and real-life surgical experience.

2. Skill Assessment: Use the assessment tools developed during task analysis to evaluate the skills of surgical teams. This can be done through structured evaluations and objective metrics.

3. Quality Improvement: Task analysis can reveal areas for process improvement. Work with the surgical team to implement changes that enhance efficiency and patient outcomes.

4. Error Prevention: Utilize the identified points of error to develop strategies for error prevention. This might involve checklists, preoperative briefings, and enhanced communication protocols.

5. Research and Innovation: Task analysis can also guide research efforts, leading to the development of new techniques and technologies that improve surgical procedures.

In conclusion, task analysis is an indispensable tool in understanding, teaching, and advancing complex surgical procedures such as laparoscopic and robotic surgeries. By meticulously dissecting each task and sub-task, identifying skill requirements, and considering cognitive processes, healthcare professionals can enhance patient safety, optimize surgical workflows, and continually improve the quality of surgical care. Task analysis is not merely an analytical exercise; it is a pathway to excellence in surgical practice.
