This video demonstrate Dr R K Mishra is performing da Vinci Robotic Cholecystectomy for Mirizzi's syndrome. Mirizzi's syndrome is a rare complication in which a gallstone becomes impacted in the cystic duct or neck of the gallbladder causing compression of the CBD (common bile duct), resulting in CBD obstruction and jaundice.

Mirizzi’s Syndrome (MS) remains one of the most formidable challenges in biliary surgery. It is a rare complication where a gallstone becomes impacted in the cystic duct or gallbladder neck, causing extrinsic compression of the Common Hepatic Duct (CHD). In advanced cases, this leads to a cholecystocholedochal fistula.

At World Laparoscopy Hospital (WLH), under the clinical leadership of Dr. R.K. Mishra, the approach to this condition has been refined into a standardized, "safety-first" laparoscopic protocol that challenges the traditional belief that MS is a mandatory indication for open surgery.

The Diagnostic Dilemma

The primary danger of Mirizzi’s Syndrome is the distortion of the Calot’s Triangle anatomy. Because the gallbladder is often densely adherent to the CHD, the risk of major bile duct injury is significantly higher than in elective cholecystectomy.

Dr. Mishra emphasizes a "pre-emptive diagnostic" approach at WLH, utilizing:

• MRCP (Magnetic Resonance Cholangiopancreatography): The gold standard for mapping the fistula and stone position.

• Intraoperative Ultrasound: Used at WLH to identify the "hidden" anatomy before the first incision is made into the biliary tissue.

Surgical Philosophy: The "Mishra Technique"

The core of Dr. Mishra’s teaching revolves around the CVS (Cygnet/Critical View of Safety). However, in Mirizzi’s Syndrome, the CVS is often impossible to achieve due to dense fibrosis. In these instances, the WLH protocol shifts to specific life-saving maneuvers:

1. The Fundus-First (Retrograde) Approach

When the anatomy at Calot’s Triangle is "frozen," Dr. Mishra advocates for the fundus-first technique. By dissecting from the fundus down to the neck, the surgeon can maintain a clearer plane of safety, preventing accidental clipping of a tented Common Bile Duct.

2. Subtotal Cholecystectomy

A hallmark of the WLH training program is knowing when to stop. If the stone is deeply embedded in the CHD wall, Dr. Mishra teaches the Laparoscopic Subtotal Cholecystectomy. By leaving a small cuff of the gallbladder neck (and removing the stones), the surgeon avoids tearing the bile duct, subsequently managing the cuff with an endoloop or internal drainage.

3. Management of Fistulas (Csendes Classification)

For Type II or III Mirizzi’s (where a fistula exists), the approach at WLH involves:

• Using the gallbladder wall remnant as a "patch" to close the defect in the CHD.

• Placement of a T-tube to act as a stent, ensuring the biliary tree remains patent during the healing phase.

Why World Laparoscopy Hospital?

The success of treating Mirizzi’s Syndrome laparoscopically at WLH is attributed to advanced ergonomics and instrumentation. Dr. Mishra’s use of high-definition 4K imaging and robotic-assisted laparoscopy allows for the precision suturing required to repair bile duct defects—a task that is exceptionally difficult in a standard laparoscopic setting.

"The goal in Mirizzi’s is not just to remove the gallbladder, but to preserve the integrity of the biliary tree at all costs." — Dr. R.K. Mishra

Conclusion

Cholecystectomy for Mirizzi’s Syndrome at World Laparoscopy Hospital represents the pinnacle of minimally invasive biliary surgery. By combining rigorous preoperative imaging with adaptive intraoperative techniques like the subtotal cholecystectomy, Dr. R.K. Mishra has demonstrated that even "impossible" gallbladders can be managed laparoscopically with outcomes that rival, or exceed, traditional open surgery.
