Because of the stomach’s generous lumen, gastrostomy tubes rarely clog. In the event that they do get clogged, carbonated liquids, meat tenderizer, or enzymes can help dissolve the obstruction. If a gastrostomy tube is left to drain, the patient may experience significant fluid and electrolyte losses, so these need to be carefully monitored.
Jejunostomy tubes are used exclusively for feeding and are usually placed 10-20 cm distal to the ligament of Treitz. These tubes are indicated in patients who require distal feedings due to gastric dysfunction or in those who have undergone a surgery in which a proximal anastomosis requires time to heal. These tubes are more apt to clog and can be more difficult to manage because the lumen of the small bowel is smaller than the stomach. Some prefer not to put pills down the tube to mitigate this risk. Routine flushes with water or saline (30 mL every four to six hours) are also helpful in mitigating the risk of clogging. In the event that they do get clogged, they may be treated like gastrostomy tubes, using carbonated liquids, meat tenderizer, or enzymes to help dissolve the obstruction.
Percutaneous tube sites should be examined frequently for signs of infection. Though gastrostomy and jejunostomy tubes are typically well secured intraabdominally, they can become dislodged. If a gastrostomy or jejunostomy tube has been in place for more than two weeks, it can easily be replaced at the bedside with a tube of comparable caliber by a member of the surgical team or by an experienced hospitalist. If the tube has been in place less than two weeks, it requires replacement with radiographic guidance, as the risk of creating a false lumen is high. Over time, tubes can become loose and fall out. If they need replacement, the preceding guidelines apply.
Back to the Case
A potential major complication of cholecystectomy is severance of the common bile duct, which necessitates significant further surgery. Less severe complications include injuries to the cholecystohepatic ducts (otherwise known as the ducts of Luschka), which can result in leakage of bile into the peritoneal cavity. A bile leak can lead to abscess and systemic infection if left undrained.
Surgeons who are concerned for such a complication intraoperatively may opt to leave a closed suction drain in the gallbladder fossa, such as a Blake drain, for monitoring and subsequent drainage. The drain will remain in place at least until the patient’s diet has been advanced fully, because digestion promotes the secretion of bile and may elucidate a leak. Bilious fluid in the Blake drain is suspicious for a leak.
The surgeon should be notified, and imaging should be obtained to find the nature of the injury to the biliary tree (CT scan with IV contrast, hepatobiliary iminodiacetic acid scan, or endoscopic retrograde cholangiopancreatography). If injury to major biliary structures (the cystic duct stump, the hepatic ducts, or the common bile duct) is diagnosed, a stent may be placed in order to restore ductile continuity.
Minor leaks, with damage to the cystic duct stump, hepatic ducts, and common bile duct ruled out, more often resolve on their own over time, and thus the patient’s closed suction drain will be left in place until biliary drainage ceases, without further initial intervention.
Bottom Line
Surgical tubes and drains have several placement indications. Alterations in quality and quantity of output can indicate changes in clinical status, and hospitalists should be able to handle initial troubleshooting. TH
