Robotic Sleeve Gastrectomy in Ascension Saint Agnes Bariatric Surgery
About the clinic
Robotic sleeve gastrectomy is a surgical weight-loss option available at Ascension Saint Agnes Bariatric Surgery in Catonsville, Maryland. The procedure uses advanced robotic technology to help patients achieve significant weight loss. This program stands out for its extensive track record, having completed over 10,000 bariatric procedures since 2001.
Robotic Surgical Precision
The clinic uses the Da Vinci XI robotic system for gastric sleeve surgeries. This technology allows surgeons to work through small incisions with the help of high-definition 3D visualization. These tools provide better precision and control during the operation. Because the incisions are small, the approach focuses on reducing physical trauma compared to traditional open surgery. The robotic system translates the surgeon's hand movements into smaller, more precise movements of tiny instruments inside the body.
Expert Surgical Team
Dr. Isam Hamdallah leads surgical interventions at the center as a specialized bariatric and metabolic surgeon. Dr. Hamdallah has personally performed 2,500+ bariatric operations. His experience contributes to the clinic's high volume of successful cases. The surgical team works within a program that has managed weight-loss journeys for thousands of patients over two decades.
Accreditations and Quality Standards
Ascension Saint Agnes Bariatric Surgery holds several national recognitions for its quality of care. It is an ACS Fully Accredited Comprehensive Center of Excellence. The facility also carries MBSAQIP accreditation, which monitors surgical outcomes and patient safety standards. These credentials show that the clinic follows strict national protocols for weight-loss surgery and follow-up care.
Support for Long-Term Success
The program follows a team-based structure to help patients maintain their results. Before surgery, every patient undergoes a psychological evaluation to prepare for the lifestyle changes ahead. The process includes:
- Initial education about the robotic sleeve gastrectomy procedure
- Surgical intervention using the Da Vinci XI system
- Long-term nutritional support from dietary experts
- Behavioral support to help manage new eating habits

Accreditations and Achievements
The American College of Surgeons recognizes the clinic as a Fully Accredited Comprehensive Center of Excellence. It also holds accreditation through the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP). This signals adherence to national quality and safety standards for surgical weight loss.
Since its founding, the surgical team has performed over 10,000 bariatric procedures. Dr. Isam Hamdallah has personally completed more than 2,500 operations. The medical team includes surgeons recognized as "Top Docs" in bariatric surgery by their peers.
Weight Loss and Metabolic Surgery
The clinic treats obesity in patients with a BMI over 40. It also treats patients with a BMI over 35 when accompanied by co-morbidities like type II diabetes. Surgeons perform several laparoscopic and endoscopic procedures:
- Roux-en-Y gastric bypass – can lead to 70% loss of excess weight within two years
- Sleeve gastrectomy – a one-to-two-hour procedure that removes about 80% of the stomach
- Endoscopic Sleeve Gastroplasty (ESG) – a non-incisional option where sutures are placed via the throat
- Biliopancreatic diversion and complex revisional bariatric surgery
Every surgical candidate undergoes a mandatory psychological evaluation led by Dawn O'Meally, LCSW-C. This assessment confirms patients are ready for the lifestyle changes required after surgery. The clinical pathway also includes nutritional counseling and bariatric nursing support certified through the ASMBS.
General and Gastrointestinal Surgery
Beyond weight loss, the team manages complex abdominal wall hernias and severe acid reflux (GERD). Specialists use surgical mesh for durable tissue support during hernia repairs. The department treats several types of hernias:
- Hiatal and paraesophageal hernias
- Incisional hernias at previous surgical sites
- Inguinal and groin hernias
- Umbilical and ventral hernias
For patients with GERD, the clinic offers Transoral Incisionless Fundoplication (TIF). This endoscopic method recreates the stomach valve without external cuts. When a hiatal hernia exceeds 2 cm, doctors often combine TIF with laparoscopic hernia repair.
Advanced Surgical Technology
Surgeons at Maryland Bariatrics use the Da Vinci XI robotic system for high-precision operations. This platform provides 3D visualization and allows smaller incisions than traditional surgery. Robotic assistance is common for both weight loss procedures and advanced hernia repairs.
The facility also features advanced endoscopic suites for upper GI diagnostics and non-surgical treatments. Doctors use manometry and pH monitoring to distinguish hiatal hernias from other conditions. Minimally invasive techniques help shorten healing times.
International Patient Services
The clinic provides dedicated support for international patients, including help with document coordination. Staff members offer services in English and Spanish for consultations and care navigation. Online educational seminars are available 24/7 with English closed captioning.
Virtual appointments with surgeons are available to discuss treatment plans before travel. Bariatric care navigators help manage insurance requirements and coordinate the multidisciplinary team. Long-term follow-up care is provided through telehealth and structured annual visits.
