Gallbladder Surgery

Direct answer
Obtain the critical view of safety before anything is clipped — Calot's triangle cleared so that only two structures, the cystic duct and the cystic artery, enter the gallbladder, with the cystic plate visible — and most bile duct injuries never happen. Laparoscopic cholecystectomy for acute cholecystitis is done early, on the index admission and ideally within 72 hours of symptom onset, graded by the Tokyo Guidelines (TG18) severity framework. When inflammation obliterates the anatomy, the bailout is a subtotal cholecystectomy rather than a heroic dissection; a recognised injury is drained, referred and reconstructed in a hepatobiliary unit, not repaired on the spot. Incidental gallbladder cancer at T1b or deeper needs oncological re-resection — a scenario Indian surgeons meet more often than most of the world.
What you must remember
- Critical view of safety: Calot's triangle cleared so only the cystic duct and artery enter the gallbladder, with part of the cystic plate visible — the SAGES-endorsed standard.
- TG18 grades acute cholecystitis I (mild) to III (severe with organ dysfunction); grade III is drained first, while grades I and II get early laparoscopic cholecystectomy within 72 hours of symptom onset — waiting increases difficulty and complications.
- Bailout options: fenestrating subtotal cholecystectomy (posterior wall left open, drain placed) or reconstituting subtotal (stump closed); both trade a stone-bearing remnant for a safe common duct.
- Bile duct injuries are classified Strasberg A–E, with E injuries (transections, strictures) further graded by Bismuth level and needing delayed hepaticojejunostomy in a specialist unit.
- Postoperative jaundice or a biloma with a "clipped" duct on imaging is an injury until proved otherwise; MRCP defines anatomy before any reoperation.
- Incidental gallbladder cancer: T1a needs nothing more after cholecystectomy; T1b (muscularis) and beyond need re-resection — segments IVb and V with hepatoduodenal lymphadenectomy, bile duct excision when the cystic stump is involved.
- Gallbladder cancer is strikingly common in north and east India — Kamrup district in Assam records among the world's highest rates, especially in women — so every specimen gets a careful opening protocol.
- Retrieve every specimen in an endobag: port-site metastasis from unsuspected cancer is a recognised disaster.
Working through a hostile gallbladder
A 54-year-old diabetic woman, day 5 of acute cholecystitis, has a tender right hypochondrial mass and a thick-walled gallbladder on ultrasound. The plan is framed before the first port: TG18 grade II disease, operated on this admission — after fluids and antibiotics — not after an interval that lets a phlegmon organise. At laparoscopy the duodenum and omentum are plastered to a gangrenous fundus and Calot's triangle is a fibrous brick. The safe move is to abandon the triangle and work fundus-first — or convert. When the triangle is undecipherable, fenestrating subtotal cholecystectomy: fundus opened, stones evacuated, posterior wall left on the liver, drain placed. The cystic duct is never clipped blind — "the operation is not worth a duct injury" is a sentence worth saying in the viva. Postoperatively, watch the drain for bile: a small leak from the remnant usually settles, but rising bilirubin with ileus suggests an injury demanding MRCP and referral rather than early reoperation.
The examiner's favourite: the incidental T1b cancer
The stem writes itself: a cholecystectomy for "polyp" or stones returns as a moderately differentiated adenocarcinoma invading muscularis, margin status unclear. The expected answer: rescan with CT and MRCP, re-explore within two to four weeks before adhesions mature, and perform segments IVb and V resection with portal lymphadenectomy, excising the cystic duct stump and adding bile duct resection only if involved. Nodes beyond the hepatoduodenal ligament indicate incurable disease, and "nothing more needed" for T1b loses the mark — the T1a-observed versus T1b-re-resected distinction is the discriminator the examiner wants.
Frequently asked questions
What constitutes the critical view of safety?
Clearing Calot's triangle so only the cystic duct and artery can be seen entering the gallbladder, with the lower third of the cystic plate visible — before either structure is divided.
When should a subtotal cholecystectomy be performed?
When inflammation, fibrosis or bleeding makes the triangle undecipherable — a fenestrating or reconstituting subtotal protects the common bile duct at the cost of a possible stone-bearing remnant.
What does Tokyo Guideline grading change?
It separates mild (I), moderate (II) and severe (III) cholecystitis: grade III needs percutaneous drainage and stabilisation first; grades I and II get early cholecystectomy on the index admission.
How is a recognised bile duct injury managed acutely?
Drainage of biliary collections, control of sepsis, imaging with MRCP, and referral for delayed reconstruction — immediate repair by the injuring surgeon in an inflamed field yields poor outcomes.
Why does T1b gallbladder cancer need more surgery?
Because muscularis invasion carries a risk of liver-bed and nodal spread (commonly cited around 10–15 per cent nodal positivity), re-resection with segments IVb–V and lymphadenectomy improves survival.
Is gallbladder cancer common in India?
Unusually so — Kamrup (Assam), Chennai and Delhi registries record among the highest rates worldwide, with a strong female predominance, which is why specimens are opened carefully.
