Overview
The term Postcholecystectomy syndrome (PCS) describes the presence of abdominal symptoms after surgery to remove the gallbladder (Cholecystectomy). Common symptoms include nausea, vomiting, bloating and diarrhea and persistent pain in the right upper quadrant of the abdomen. [1]
Historical Perspective
In 1960, a gastroenterologist named Freud M., surveyed 114 patients who had undergone cholecystectomy and found 93% of the patients had pain, 24% had jaundice and 38% had fever.[2]
Classification
There is classification of post cholecystectomy syndrome on basis of involvement of intestinal tract.
Pathophysiology
Most often laproscopic surgeries lead to trauma or remembrance of stone, which are background players of cholecystectomy syndrome. The pathogenesis of post-cholecystectomy syndrome also includes bile leakage from an overlooked transection of normal or aberrant bile ducts, obstructive jaundice due to inadvertent ligation of the common bile duct or its postsurgical stricture, instrumentation injuries induced during biliary tract exploration, and various types of biliary fistulas.[3]
Causes
Post-cholecystectomy syndrome may be caused due to bile duct injury, biliary leak, biliary fistula and retained bile duct stones. If left untreated it can lead to recurrent bile duct stones and bile duct strictures.[4][5][6]
Biliary causes:
Early post-cholecystectomy syndrome
The causes of early post-cholecystectomy syndrome include the following:
- Retained stones in the cystic duct stump and/or common bile duct
- Bile duct injury/ligature during surgery
- Bile leakage
Late post-cholecystectomy syndrome
The causes of late post-cholecystectomy syndrome include the following:
- Recurrent stones in the common bile duct
- Bile duct strictures
- Cystic duct remnant harbouring stones and/or inflammation
- Gallbladder remnant harbouring stones and/or inflammation
- Papillary stenosis
- Biliary dyskinesia
Extrabiliary causes:
The extrabiliary causes of post-cholecystectomy syndrome may be classified into gastrointestinal causes and conditions outside of the gastrointestinal tract that may lead to this syndrome. The causes are as follows:
Gastrointestinal causes
- Acute/chronic pancreatitis (and complications)
- Pancreatic tumors
- Pancreas divisum
- Hepatitis
- Esophageal diseases
- Unexplained pain syndromes
- Peptic ulcer disease
- Mesenteric ischemia
- Diverticulitis
- Organic or motor intestinal disorders
Extra-intestinal causes
- Psychiatric and/or neurological disorders
- Coronary artery disease
- Intercostal neuritis
- Wound neuroma
- Unexplained pain syndromes
Differentiating Postcholecystectomy syndrome from Other Diseases
Common differentials of post-cholecystectomy syndrome are:
- Organic extrabiliary diseases: Esophagitis, gastritis, pancreatitis, costochondritis.
- Organic biliary diseases: Residual stone, strictures, benign or malignant tumors of the Vater papilla and the periampullary, choledochal cyst
- Functional extrabiliary conditions: Irritable bowel syndrome (IBS)
- Functional biliary conditions: Sphincter of Oddi dysfunction (SOD)
Epidemiology and Demographics
Around 15 to 20 % of patients going through cholecystectomy experience PCS symptoms.
Risk Factors
Following are risk factors of PCS:
- Laparoscopic surgery
- Inexperienced surgeon
- Irritable bowel syndrome
Screening
Patients after cholecystectomy may experience symptoms as pain, jaundice and or fever should be evaluated for PCS.
Natural History, Complications, and Prognosis
PCS complications depend on the cause of behind it. Patients having functional cause are easy to recover in few weeks.
Natural History:
If left untreated PCS, can lead to possible discomfort in life style. In patients having stone left behind in their bile duct or gallbladder may develop obstructive jaundice.
Prognosis:
Prognosis depends on the cause behind the cause of PCS. In general, it is good in patients having no underlying cause.
Diagnosis
PCS is diagnosis for time being. Work done after symptoms com to medical attention help in categorizing the cause as either functional or organic.
Diagnostic Criteria:
Patient presenting with symptoms should be evaluated with Abdominal ultrasound and blood tests for CBC and LFT's.
History and Symptoms:
Patient may present with abdominal pain, jaundice or dyspeptic symptoms.
Physical Examination:
Patient may have jaundice or right upper quadrant pain.
Laboratory Findings:
Elevated levels of LFT's would indicate stone retention or stricture formation..
Following are normal levels:
- ALT. 7 to 55 units per liter (U/L)
- AST. 8 to 48 U/L
- ALP. 45 to 115 U/L
- Albumin. 3.5 to 5.0 grams per deciliter (g/dL)
- Total protein. 6.3 to 7.9 g/dL
- Bilirubin. 0.1 to 1.2 milligrams per deciliter (mg/dL)
- GGT. 9 to 48 U/L
- LD. 122 to 222 U/L
- PT. 9.5 to 13.8 seconds

Imaging Findings:
Trans abdominal ultrasound and ERCP helps in obtaining exact cause of post cholecystectomy syndrome.
Treatment
Treatment of PCS depends on the cause and symptoms. Once the cause is established the treatment can be wither surgical or medical.[7]
Medical Therapy
Treat options are available for following symptoms of PCS:
- 1 Irritable bowel syndrome :
- bulking agents
- sedatives
- antispasmodics
- 2 Irritable sphincter:
- high-dose calcium channel blockers
- nitrates
- 3 gastroesophageal reflux disease
- antacids,
- Histamine 2 (H2) blockers,
- Proton pump inhibitors (PPIs)
Surgery
Surgery is helpful for :
- Remnant gallbladder or remnant cystic duct lithiasis
- Sphincterotomy through for patient have debilitating, intermittent right-upper-quadrant pain, and no diagnosis is found.
- Bile duct injury/ligature during surgery
- Bile leakage
- Papillary stenosis
- Biliary dyskinesia
Prevention
Rowachol is being used to prevent PCS.[8]
