Al-Khobar – Mouwasat Hospital 

In a remarkable achievement at the level of the Kingdom, the medical team at Mouwasat Hospital in Al-Khobar successfully removed a rare 15 cm desmoid tumor from the small bowel mesentery using advanced robotic surgical technology

Case Details 

A female patient in her thirties presented with abdominal swelling. After conducting the necessary diagnostic evaluations, imaging revealed a large tumor located within the mesentery of the small intestine, which was anatomically connected to the stomach due to a previous mini-gastric bypass procedure. 

Robotic Surgical Intervention 

The tumor was completely excised using the robotic surgical system with exceptional precision, while preserving the main arterial supply to the remaining small intestine. A classic bypass reconstruction was also performed to ensure optimal postoperative function. 

Dr. Sami Al-Assari – consultant of robotic surgery, oncology, colon & rectal surgery, and bariatric surgery explained that the robotic platform significantly contributed to the success of the operation by enabling:

What is a desmoid tumor? 

Desmoid tumors are rare and often challenging to remove due to their tendency to grow aggressively and adhere to surrounding tissues. This case highlights the critical role of robotic surgery in performing such delicate and complex procedures safely and effectively.

Al-Khobar – Mouwasat Hospital 

The medical team at Mouwasat Hospital in Al-Khobar has successfully performed a robotic-assisted excision of a cancerous tumor located in the lower rectum for a patient in his forties, achieving a highly precise and safe surgical outcome. 

Preoperative Treatment Plan 

The patient was diagnosed with lower rectal cancer, and a comprehensive treatment plan was established, beginning with chemotherapy followed by radiotherapy to reduce the tumor size and prepare for optimal surgical intervention. 

Robotic Surgical Intervention

The rectal excision procedure was carried out using the robotic surgical system under the leadership of Dr. Sami Al-Assari – Consultant of General Surgery, Robotic Surgery, and Colon & Rectal Surgery

The robotic platform played a crucial role in achieving excellent surgical precision, particularly in this challenging case, by enabling: 

  • Smooth access to the narrow pelvic cavity, 
  • Effective management of the additional complexity caused by the patient’s morbid obesity, 
  • High-precision preservation of pelvic muscles and critical nerves, 
  • Minimal intraoperative bleeding, 
  • Enhanced accuracy in stapling and reconnecting the colon in the lower pelvis. 

Surgical Outcome

By the grace of God, the surgery was completed successfully, the tumor was fully removed, and the patient recovered quickly. He was discharged in good health with no reported complications. 

This achievement reinforces the advanced capabilities of Mouwasat Hospital in Al-Khobar in performing highly complex oncological procedures using state-of-the-art robotic surgery, contributing to improved patient outcomes and faster recovery times.

Al-Khobar – Mouwasat Hospital 

The medical team at Mouwasat Hospital in Al-Khobar has successfully performed a corrective surgery for a recurrent inguinal hernia in a patient in his forties, using advanced robotic surgical technology. This achievement marks the first procedure of its kind in the private healthcare sector. 

Case Details 

The patient visited the general surgery clinic one year after undergoing a laparoscopic inguinal hernia repair with mesh placement at another hospital. Unfortunately, the hernia reappeared within the first month after the initial operation, causing discomfort and prompting the patient to seek specialized care at Mouwasat Hospital in Al-Khobar. 

Medical Evaluation and Surgical Intervention 

Following a comprehensive evaluation, the medical team—led by Dr. Sami Al-Assari, Consultant of General Surgery, Obesity Surgery, Robotic Surgery, and Colon & Rectal Surgery, decided to perform a corrective robotic surgery due to the complexity and sensitivity of the case. 

The robotic system enabled precise tissue dissection, complete removal of the recurrent hernia, and accurate placement of the mesh. The technology played a key role in reducing bleeding, minimizing postoperative pain, and protecting the vital structures surrounding the hernia site. 

Surgical Outcome 

By the grace of God, the surgery was successful, and the patient was discharged in good health and without complications. 
This accomplishment further strengthens the position of Mouwasat Hospital in Al-Khobar as a leading center for advanced robotic surgeries in the region.
