Robot-assisted vs. traditional sleeve gastrectomy
This study compares two types of weight-loss surgery: one done with the help of a robot and the other done by hand (laparoscopic).

This trial compares two different numbing injection techniques to help control pain after surgery above the belly button. It may help people who qualify have better or longer-lasting pain relief with fewer side effects.
Damanhūr, El-BeheiraAges 21–60 - NCT07507799Recruiting
Comparing low vs standard dose block for gallbladder surgery
This trial tests two different amounts of a numbing medicine (local anesthetic) given during gallbladder removal surgery. The goal is to see if a lower dose works just as well for pain control.
El Fayoum Qesm, Faiyum GovernorateAges 18–65 - NCT07388953Recruiting
Nerve block for better pain relief after colon surgery
This study tests adding a special nerve block (peripheral autonomic block) to a standard abdominal wall block to see if it provides better pain relief after minimally invasive left-sided colon surgery. It may help patients experience less pain and use fewer pain medications.
