Postcholecystectomy syndrome: symptom clusters after laparoscopic cholecystectomy

Area of Science:

• Gastroenterology
• Surgical Outcomes Research

Background:

• Postcholecystectomy syndrome (PCS) presents with diverse abdominal symptoms after gallbladder removal.
• A lack of consensus exists regarding the precise definition and treatment strategies for PCS.
• Understanding PCS is crucial for improving patient care after cholecystectomy.

Purpose of the Study:

• To establish a clear definition for postcholecystectomy syndrome (PCS) based on symptom clusters.
• To identify potential risk factors associated with the development of PCS following laparoscopic cholecystectomy.

Main Methods:

• Factor analysis was employed to identify distinct symptom clusters from patient-reported outcomes.
• Ward's method and Dentogram were utilized for cluster analysis to evaluate risk factors.
• The European Organization for Research and Treatment of Cancer QLQ-C30 questionnaire assessed patient outcomes.

Main Results:

• Three significant symptom clusters were identified: 'insomnia and financial difficulties,' 'appetite loss and constipation,' and 'right upper quadrant (RUQ) pain and diarrhea.'
• The 'RUQ pain and diarrhea' cluster was determined to be characteristic of PCS.
• No significant risk factors were identified differentiating high and low symptomatic groups.

Conclusions:

• Postcholecystectomy syndrome (PCS) can be defined by the presence of right upper quadrant pain and diarrhea.
• Prospective studies are essential to elucidate the risk factors contributing to PCS.
