Other complications and their management

Most complications are recognised late because nobody expected them. Expect them.

Three things to remember
  1. Control bleeding with pressure and a clear view, never blind clips or diathermy near the duct.
  2. A patient unwell on day two to four has a bowel injury or a bile leak until a CT says otherwise.
  3. Grade by Clavien-Dindo, retrieve spilled stones, and remember post-cholecystectomy syndrome is usually something else.

01How often things go wrong

8.0%
any complication at 30 days (AMBROSE, 21,706 operations, 57 countries)
1.3%
bile leak
0.2%
severe bile duct injury
0.4%
30-day mortality

Predictors: age, ASA grade, urgent setting and the Nassar difficulty grade. Bile duct injury has its own page. This page covers everything else: how it happens, how to recognise it, what to do, how to prevent it.

The rule for the first week
Pain needing opioids after 24 hours, a pulse over 100, a fever, a bilious drain, jaundice, or a patient who does not want to eat: none of these is “normal” after a laparoscopic cholecystectomy. Each needs an examination, bloods and, usually, imaging the same day.
Sources

AMBROSE, Ann Surg 2025. Observational benchmarks Estonian national series of 29,739 operations: bile duct injury of any kind 0.81 percent, major 0.13 percent (Reinsoo et al., Eur J Trauma Emerg Surg 2023).

02Bleeding

Sources

On the table: cystic artery or branch, liver bed, port sites, rarely middle hepatic vein branches near the cystic plate or a major vessel at entry.

After: slipped cystic artery clip, liver bed, a port-site vessel such as the inferior epigastric artery. Tachycardia, falling haemoglobin, distension, blood in the drain within 24 hours.

On the table

Pressure with the gallbladder or a swab, suck, irrigate, get a clear view before any clip or energy. A bleeding cystic stump retracts towards the right hepatic artery: blind clips here make vasculobiliary injuries.

Conversion for uncontrolled bleeding is the one unarguable indication

After the operation

Resuscitate, cross-match, reverse anticoagulation. Unstable: back to theatre. Stable with falling haemoglobin: CT angiogram; an arterial blush is embolised, a port-site bleed is explored.

Most post-operative bleeding is self-limiting

Prevent

Stop anticoagulants and antiplatelets per policy. Close port sites above the epigastric vessels under vision. Check the bed and stump at 8 mmHg before removing ports: 15 mmHg tamponades venous bleeding.

03Bowel and visceral injury

Know this
  • About 0.1 to 0.3 percent of operations (textbook-level figure, not re-verified). Three ways: at entry, during adhesiolysis of duodenum or colon stuck to the gallbladder, and thermal injury not seen (direct contact, capacitive coupling, insulation failure). The duodenum is the commonest victim.
  • Seen on the table: repair on the table, laparoscopically if exposure allows. The dangerous injury is the one not seen.
  • Thermal injuries declare at 3 to 7 days as the burn perforates. Severe pain and sepsis in the first week: CT with oral contrast and a low threshold for laparoscopy. Only about half of bowel injuries are recognised at surgery.
Prevent
  • Open (Hasson) or Palmer’s point optical entry after previous surgery.
  • Keep the whole uninsulated hook in view; short bursts.
  • Inspect handled bowel before closing. Expert opinion
Don’t
  • Activate the diathermy when it is not touching the target.
  • Activate it while it touches another metal instrument.
  • Send home the patient with pain and sepsis on day 4 as “normal”.

04Spilled gallstones

6–40%
of operations perforate the gallbladder
~16%
spill stones
16–50%
of spilled stones are not retrieved
36 months
median interval to a complication (abscess in 56 percent of reports)
27%
of spillage documented in the note
  • Complications are rare (well under 1 percent of all operations) but strange and late: abscess, fistula to skin or bowel, empyema from stones migrating through the diaphragm, masses mistaken for tumours.
  • Retrieve every stone you reasonably can with suction, a bag and irrigation. Fragments and bile that cannot be retrieved are not a reason to convert. Pigment stones and infected bile carry the higher risk.
  • Document the spillage, the approximate number and what was retrieved. Tell the patient. Stones near the liver on later imaging in a patient with an abscess are the diagnosis; drain and remove the stones, which are the nidus.

05Retained common bile duct stones

10–15%
of patients with gallstones have duct stones
40–50%
of those are silent at cholecystectomy
2–15%
still have stones on cholangiography after pre-operative ERCP
1–2%
symptomatic retained stones after cholecystectomy without duct imaging
Know this
  • Early (weeks): pain, jaundice, cholangitis, pancreatitis, or a cystic stump leak because the duct is obstructed downstream. Late (months to years): often stones formed since, especially above a stricture.
  • Liver tests and ultrasound first; magnetic resonance cholangiopancreatography (MRCP) if the duct is dilated or the picture is unclear; endoscopic retrograde cholangiopancreatography (ERCP) with sphincterotomy and extraction is the treatment after cholecystectomy (ASGE 2019). Failed ERCP: cholangioscopy and lithotripsy, percutaneous access, or surgical exploration.
  • Prevention is risk stratification and duct imaging (indications page). Routine cholangiography finds unsuspected stones in about 2 to 4 percent; SAGES 2025 suggests it on low-certainty evidence. Contested

06Bile leak: cystic stump and ducts of Luschka

Four sources: the cystic stump (slipped, cut-through or misplaced clip; the commonest), a subvesical duct of Luschka in the cystic plate, the remnant after a fenestrating subtotal, or a bile duct injury. The first three are Strasberg A with an excellent prognosis. The first task is to tell them from the fourth.

  1. Recognise. Bile in the drain, or more often a patient without a drain who returns on day 2 to 5 with pain, bloating, low fever, nausea and a raised bilirubin or CRP. Bile peritonitis takes days to develop and kills the patient sent home as “normal”.
  2. Drain the collection (ultrasound or CT, then a radiological drain). Bile in the drain confirms the leak.
  3. Define the anatomy: MRCP, or ERCP directly in a patient who will need one. A continuous normal duct means a minor leak. A duct that stops, is clipped or does not fill above a level is an injury: bile duct injury page.
  4. Treat the minor leak. If adequately drained and clinically improving, observe closely. Arrange ERCP for persistent or high-output leakage, retained stones, failure to improve or deterioration; do not wait seven days in a worsening patient. ERCP with biliary stenting, with or without sphincterotomy as appropriate, usually controls leaks with preserved duct continuity; arrange stent removal, commonly at 4 to 6 weeks. Re-laparoscopy with washout and re-clipping is reasonable in the first days with peritonitis and an obvious stump leak, but it does not treat an obstructed duct.
Do not
Do not treat a leak with antibiotics and watching without draining the collection. Do not assume a stump leak until imaging shows the common duct intact. A leak plus a clip on the common duct is the classic missed Strasberg E injury.

WSES 2021 bile duct injury guideline, 7.1–7.2: initial observation after adequate drainage is an option (weak recommendation, low quality); failure to improve or deterioration requires endoscopic management when anatomically appropriate (strong recommendation, low quality). The guideline does not prescribe a seven-day waiting period. Guideline

07Port-site hernia

  • Roughly 1 to 2 percent (textbook-level figure, not re-verified), at the umbilical or extraction site, usually within a year. More with ports of 10 mm or more, obesity, wound infection and unclosed fascia.
  • A bulge, pain or small bowel obstruction. A Richter hernia through a small port defect can strangulate without a lump.
  • Repair, with mesh beyond a small defect.
  • Prevent: close the fascia of every port of 10 mm or more, and any dilated extraction site, under vision; a closure device helps in the obese. Enlarge the umbilical incision rather than force the gallbladder through it. Expert opinion with observational support

08Post-cholecystectomy syndrome

5–47%
have persisting or new symptoms, depending on how the question is asked (Merck Manual)
61–63%
pain-free at five years in SECURE: more than a third still had pain
5–10%
bile-acid diarrhoea, which responds to a sequestrant

“Post-cholecystectomy syndrome” is a label, not a diagnosis.

Post-cholecystectomy syndrome
GroupCauses
BiliaryRetained or recurrent duct stones, stricture or injury, long cystic remnant with stones, sphincter of Oddi dysfunction
Abdominal, not biliaryPeptic ulcer, irritable bowel, functional dyspepsia, pancreatitis, hernia, bile-acid diarrhoea
Not abdominalMusculoskeletal, cardiac, psychological
The gallbladder was never the causeThe largest group
Do
  • Take the history again. Pain identical to the old colic, with abnormal liver tests or a dilated duct: MRCP first; endoscopic ultrasound for small stones.
  • Have the honest conversation at consent, before the operation (consent).
Don’t
  • Do an ERCP “to have a look” in a patient with different pain, normal bloods and a normal duct: post-ERCP pancreatitis in a normal duct is a disaster.

09Other problems worth knowing

Other problems worth knowing
ProblemPresentsManagement
Wound infection (umbilical port most often)Day 3 to 7, red, dischargingOpen and drain; antibiotics only for cellulitis; about 1 to 2 percent with prophylaxis in acute cholecystitis (PEANUTS II)
Subhepatic collection without leakDay 5 to 14, fever, painUltrasound or CT; drain if large or septic; antibiotics
Gas embolismOn the table, usually at insufflation: sudden fall in end-tidal CO2, hypotension, desaturation, a mill-wheel murmurStop insufflation and deflate, 100 percent oxygen, left lateral head-down, support the circulation, aspirate gas through a central line if one is in; rare but lethal
Subcutaneous emphysemaCrepitus of the abdominal wall, chest or neck with a rising end-tidal CO2Lower the insufflation pressure or deflate, increase ventilation; settles within hours; look for a pneumothorax if it is extensive
Pneumothorax (capnothorax)Rising airway pressures, falling saturation, a rising end-tidal CO2; hypotension if under tensionDeflate, 100 percent oxygen, decompress a tension pneumothorax at once; a capnothorax without tension often resolves with ventilation and does not always need a drain
Venous thromboembolismAny time in 90 daysRisk assess; mechanical and drug prophylaxis per policy; low baseline risk after day-case surgery
Diathermy burn, remote burnFound at the endDress; report as an equipment incident
Shoulder-tip pain, vasovagalDay 0 to 2Reassure, simple analgesia; lower pressure and evacuate gas at the end
Hepatic artery pseudoaneurysmWeeks later: haemobilia, pain, jaundice, upper GI bleedingCT angiogram and embolisation; nearly always after a difficult dissection or leak

VDeath

A leak treated by ERCP and stent is IIIa; a duct injury repaired at laparotomy is IIIb. Every exam expects it, and it makes your audit comparable with the literature.

11What examiners ask

  1. Day 3, pain and a bilirubin of 3.5 mg/dL: differential and what you do, in order.
  2. Sources of a bile leak and how you tell a minor leak from a duct injury.
  3. Why thermal bowel injuries present late, and what that means on day 5.
  4. What you write in the note after spilling stones, and why.
  5. What you tell a patient whose pain has not gone after an uncomplicated cholecystectomy.
