Robotic Surgery for Other Conditions Treatment

Robotic surgery has emerged as a groundbreaking approach in the treatment of gynaecological cancers. It offers a minimally invasive alternative for conditions such as:

Endometriosis

Endometriosis is a condition where tissues lining the uterus grow outside the uterus, often causing severe pain. Robotic surgery is a safe and effective technique for endometriosis patients. It allows surgeons to precisely remove endometrial tissue, resulting in less scarring, reduced pain and improved outcomes compared to regular laparoscopy.

Abdominal Pain And Pelvic Pain

Abdominal pain and pelvic pain can also be symptoms of gynaecological cancers, such as ovarian cancer and uterine cancer. These conditions require specialised treatment, and robotic surgery has emerged as an effective approach. By utilising robotic-assisted technology, surgeons can perform precise and targeted procedures to address gynaecological cancers, alleviating pain and improving outcomes for patients.

Uterine Fibroids

Robotic surgery, specifically robotic myomectomy (a type of laparoscopic myomectomy) is often used by surgeons to remove uterine fibroids. With robotic myomectomy, one may experience less blood loss, fewer complications, a shorter hospital stay and a faster return to everyday activities.

Gynaecological Cancer

Robotic surgery is highly effective in treating advanced gynaecological cancers. Procedures like oophorectomy, hysterectomy, lymphadenectomy and radical hysterectomy can be performed with precision. However, individual factors and cancer stage determine the specific treatment approach.

Complications Related With Robotic Surgery

Robot-assisted surgery is usually safe and the incidence of complications is low. However, complications may arise directly or indirectly related to the robotic system. The causes of complications are careless handling of instruments, insulation failure, lack of communication between doctors and inadequate uterine elevation resulting in organ damage.

Surgical Complications

Surgical complications can be broadly classified into two groups:

1. Intraoperative Complications: Ureteric damage, bladder damage, vascular damage etc.
2. Postoperative Complications: This group can be further divided into three subgroups:
• Immediate: Haemorrhage, nausea, vomiting etc
• Intermediate: Infection, haematomas etc
• Late: Incisional hernia, bowel obstruction etc

Instrument Or System Malfunctions

Robotic surgery has experienced rapid growth in the surgical field since its approval. In clinical practice, failure of robotic surgery occurs due to a surgeon’s fault or device malfunction. Device malfunctions are rare occasions. Data represents that only 20.9% of surgical complications arise due to malfunction of robotic surgery arms and instruments.

Surgeon Learning Curve

During the process of learning a new surgical procedure, surgeons typically enhance their performance and skills through experience and practice. This improvement can be represented by a learning curve when plotting performance against experience. Studies on robotic surgeries indicate that surgeons generally reach a point of proficiency, or complete their learning curve, after approximately two years or after completing 12-15 surgical cases. As surgeons gain more experience, they become more efficient, leading to reduced length of hospital stays for patients.

Pneumoperitoneum-Related Issues

Pneumoperitoneum is the presence of gas or air in the peritoneal or abdominal cavity. Pneumoperitoneum-related complications in robotic surgery include subcutaneous emphysema, pneumothorax and hypercarbia. The complication rate is nearly 2.3% for subcutaneous emphysema, 1.9% for pneumothorax and 5.5% for hypercarbia in patients which can be solved spontaneously within 2-3 days.

Other Robotic Surgery for Gynaecological Cancer Treatments

Robotic surgery is a minimally invasive approach to treating gynaecological cancers that often cause minimal bleeding, scarring and postoperative pain and discomfort than other traditional surgical options. Different surgical treatment methods for gynaecological cancers include:

Robotic Hysterectomy

Robotic hysterectomy is a surgical procedure that involves the removal of the uterus (hysterectomy) or the uterus along with the cervix (total hysterectomy). During this robotic surgery, doctors use instruments passed through small abdominal incisions. This allows the doctors to have a 3D view of the uterus, enabling them to perform the surgery with precision, flexibility, and control.

Robotic Lymph Node Dissection

Nowadays, lymph node dissections are commonly performed using robotic techniques, unlike traditional lymphadenectomy procedures. The main difference between these procedures is that in robotic surgery, the surgeon uses the da Vinci Robotic System to perform lymph node dissections. The advantages of robotic lymph node dissection are:

• Reduced visibility of bruising or cosmetic blemishes
• Decreased pain and discomfort for patients
• Shorter recovery period with improved outcomes
• Fewer activity restrictions during the recovery phase
• Enhanced surgical accuracy

Robotic Debulking Surgery

Robotic debulking surgery is a surgical procedure aimed at removing a significant portion of tumor tissue, without aiming for complete eradication. This may result in a small amount of cancerous tissue remaining in the body. Reports indicate that 79% of patients who underwent debulking surgery experienced a complete clinical response, compared to 59% of patients who did not undergo this surgery.
