Indications, contraindications and pre-operative workup

The SAGES guideline for laparoscopic biliary tract surgery, last revised in 2010, remains the reference list of indications in North America. It names laparoscopic cholecystectomy as the treatment of choice for symptomatic gallstones, acute cholecystitis, and gallstone pancreatitis once the pancreatitis has settled (SAGES guidelines for the clinical application of laparoscopic biliary tract surgery, 2010). Guideline, dated Its evidence grades predate the trials cited below, so where the two differ this page follows the newer source.

Gallstone pancreatitis: cholecystectomy during the index admission for mild pancreatitis, once settled, reduces readmission for recurrent biliary events (PONCHO trial, da Costa et al., Lancet 2015). Randomised trial UK guidance asks for definitive treatment of the gallstones during the same admission, or a clear plan for it within two weeks (UK working party guideline, Gut 2005); the NICE pancreatitis guideline (NG104, 2018) also covers gallstone treatment after pancreatitis. Polyp thresholds are from the joint European (ESGAR/EAES/EFISDS/ESGE) 2022 guidance (Foley et al., Eur Radiol 2022).

What to tell patients. In the Dutch SECURE trial, only about 60 percent of patients with gallstones and abdominal pain were pain-free at one year, whether they had usual care or a restrictive selection strategy. About 62 percent were pain-free at five years (Comes et al., JAMA Surg 2024).

C-GALL. In 434 adults with uncomplicated symptomatic gallstones at 20 British hospitals, surgery and observation gave no difference in bodily pain over 18 months (mean difference 0.0 on the SF-36 pain scale, 95 percent confidence interval −1.7 to 1.7). A quarter of the conservative group came to cholecystectomy within 18 months. Complications were similar (15 versus 20 percent), and conservative management was cheaper (Ahmed et al., BMJ 2023). Randomised trial Contested Patients with unsettled cholecystitis, duct stones, jaundice, pancreatitis or suspected cancer were not in the trial, and the longer-term results are still awaited.

Septic shock: Pisano et al., WSES 2020. Pregnancy: Kumar et al., SAGES pregnancy guideline 2024 conditionally favours surgery for acute cholecystitis (low certainty); third-trimester biliary colic may be managed operatively or non-operatively. See pregnancy.

WSES states plainly that raised liver tests or bilirubin alone are not enough to diagnose duct stones, and that a dilated duct alone is not enough either (Pisano et al., WSES 2020). Guideline The upper limit of duct diameter rises with age and after previous sphincterotomy.

About 10 to 15 percent of patients with symptomatic gallstones also have stones in the common bile duct, and SAGES estimates that 40 to 50 percent of those are silent. Among patients who have had pre-operative ERCP, a further 2 to 15 percent still have stones on intra-operative cholangiography (SAGES clinical spotlight review on laparoscopic common bile duct exploration; the 10 to 20 percent figure in the ASGE guideline refers to symptomatic cholelithiasis). The table uses the 2019 ASGE scheme (Buxbaum et al., Gastrointest Endosc 2019). Guideline

WSES uses a more cautious modified pathway for acute cholecystitis: a duct stone on ultrasound leads directly to therapeutic ERCP; bilirubin over 4 mg/dL, or duct dilatation with bilirubin 1.8 to 4 mg/dL, prompts EUS, MRCP, laparoscopic ultrasound or IOC first (WSES acute cholecystitis guideline, 2020, section 2). This stone-risk pathway does not replace urgent drainage for cholangitis.

MRCP is the usual test for the intermediate group in Europe and India because it is non-invasive; its sensitivity falls for stones under 5 mm. Endoscopic ultrasound is more sensitive for small stones but needs an endoscopist and sedation. ERCP is a treatment, not a screening test, with a 3 to 10 percent risk of pancreatitis. The 2019 ESGE guideline advises against diagnostic ERCP and recommends cholecystectomy within two weeks of ERCP in fit patients, because waiting longer increases recurrent biliary events (Manes et al., Endoscopy 2019). Guideline

ERCP first, or a single-stage operation? The SAGES spotlight review sets out the transcystic and transcholedochal techniques, the equipment and the case for a single-stage operation where the expertise exists. Laparoscopic cholecystectomy with laparoscopic duct exploration clears the duct in one anaesthetic with equal success and a shorter total stay compared with ERCP followed by cholecystectomy (Dasari et al., Cochrane 2013). In most units the limiting factor is skill with the choledochoscope, and the two-stage pathway remains commoner. Contested The choice is driven more by local expertise than by evidence.

For twenty years most surgeons outside Australia and Scandinavia used cholangiography selectively. In 2025 the SAGES guideline on intra-operative imaging of the common bile duct made two conditional recommendations, based on low-certainty evidence. It favoured routine rather than selective cholangiography in adults, with exceptions such as pregnancy, and X-ray cholangiography over ICG fluorescence (Kumar et al., Surg Endosc 2025). Guideline Contested The panel acknowledged that the benefit is uncertain, and the earlier WSES bile duct injury guideline recommended against routine cholangiography (de’Angelis et al., 2021). The June 2026 clarification is at SAGES clarification, June 2026. The detailed comparison with ICG is on the ICG page.

The Surgical Infection Society recommends against routine perioperative antibiotics in low-risk elective laparoscopic cholecystectomy (Colling et al., Surgical Infection Society 2022). This recommendation is distinct from proof of no benefit: the older Cochrane review found insufficient evidence to support or refute a reduction in infection (Sanabria et al., Cochrane 2010). Systematic review Many units still give a single dose to patients considered higher risk (age over 60 or 70, diabetes, jaundice, recent colic or cholecystitis, immunosuppression, bile spillage or prosthetic implants). Expert opinion

PEANUTS II randomised 457 patients having cholecystectomy for mild or moderate acute cholecystitis to a single pre-operative dose of cefazolin 2 g or no prophylaxis. Infectious complications occurred in 7.1 percent with prophylaxis and 12.6 percent without. Non-inferiority of omitting antibiotics was not shown, and surgical-site infection was significantly higher without prophylaxis (van Braak et al., Br J Surg 2022). Randomised trial In the French trial of 414 patients, continuing amoxicillin-clavulanate for five days after cholecystectomy did not reduce infection compared with stopping at the end of the operation (Regimbeau et al., JAMA 2014). WSES 2020 makes a strong recommendation against routine post-operative antibiotics for uncomplicated acute cholecystitis once the source is controlled. Guideline Tokyo Guidelines 2018 give a severity-based antimicrobial table (Gomi et al., 2018).

Foley et al., Eur Radiol 2022 (ESGAR, EAES, EFISDS and ESGE joint guideline). Guideline The American Hepato-Pancreato-Biliary Association consensus also advises resection of polyps over 1 cm or with a vascular stalk on imaging (Aloia et al., HPB 2015). Consensus
