Management of Post-Cholecystectomy Constipation

Causes of Constipation

Opioid-induced constipation is the most frequent cause of constipation after cholecystectomy, as opioids given during anesthesia or for postoperative pain relief persistently slow gastrointestinal motility 1
Anesthesia effects on bowel function, with longer surgical duration associated with higher risk of constipation 1
Reduced mobility during the early recovery period contributes to constipation 1

The National Comprehensive Cancer Network recommends increasing fluid intake to promote softer stools 2
The National Comprehensive Cancer Network suggests increasing dietary fiber only if the patient has adequate fluid intake and physical activity 2
Encourage exercise and mobilization as appropriate for recovery stage, as recommended by the National Comprehensive Cancer Network 2
Discontinue non-essential constipating medications, as advised by the National Comprehensive Cancer Network 2

The National Comprehensive Cancer Network recommends bisacodyl 10-15 mg daily to three times daily with a goal of one non-forced bowel movement every 1-2 days 2
The National Comprehensive Cancer Network suggests senna plus docusate (stool softener): 2-3 tablets twice to three times daily 2
If inadequate response, add polyethylene glycol (MiraLAX): 1 capful in 8 oz water twice daily, as recommended by the National Comprehensive Cancer Network 2
Lactulose 30-60 mL twice to four times daily may be considered for constipation management, according to the National Comprehensive Cancer Network 2
Magnesium hydroxide (Milk of Magnesia) 30-60 mL daily to twice daily may be used for constipation relief, as suggested by the National Comprehensive Cancer Network 2

Rule out fecal impaction through physical examination, especially if diarrhea accompanies constipation, as recommended by the National Comprehensive Cancer Network 2
Glycerine suppository with or without mineral oil retention enema may be used for severe constipation, according to the National Comprehensive Cancer Network 2
Bisacodyl suppository (one rectally daily to twice daily) may be considered for constipation relief, as suggested by the National Comprehensive Cancer Network 2
Manual disimpaction following pre-medication with analgesic and/or anxiolytic if needed may be necessary for severe constipation, as recommended by the National Comprehensive Cancer Network 2

Methylnaltrexone 0.15 mg/kg subcutaneously every other day (no more than once daily) may be considered for opioid-induced constipation, except in cases of post-operative ileus or mechanical bowel obstruction, as recommended by the National Comprehensive Cancer Network 2
Multimodal analgesia combining regional analgesia, non-opioid analgesics (acetaminophen, NSAIDs), and other adjuncts has been shown to reduce opioid requirements and accelerate gastrointestinal recovery, according to the World Journal of Emergency Surgery 1

Do not ignore alarm symptoms: if constipation is accompanied by fever, severe abdominal pain, distention, jaundice, nausea, or vomiting, investigate immediately for serious complications, as advised by the National Comprehensive Cancer Network 2
Rule out mechanical obstruction: perform physical examination and consider abdominal x-ray if obstruction is suspected, as recommended by the National Comprehensive Cancer Network 2
Avoid increasing fiber without adequate hydration, as this can worsen constipation, according to the National Comprehensive Cancer Network 2
Monitor for impaction: diarrhea in the setting of constipation may represent overflow around an impaction, as suggested by the National Comprehensive Cancer Network 2

Consider further evaluation if constipation persists despite aggressive laxative therapy, as recommended by the National Comprehensive Cancer Network 2
Signs of bowel obstruction appear (distention, inability to pass gas, vomiting), according to the National Comprehensive Cancer Network 2
Systemic symptoms develop (fever, jaundice), as advised by the National Comprehensive Cancer Network 2
