Perioperative Nasogastric Decompression Strategies in Laparoscopic Pancreaticoduodenectomy: A Propensity Score–Matched Retrospective Cohort Study
This propensity score–matched retrospective study of 957 patients undergoing laparoscopic pancreaticoduodenectomy demonstrates that complete perioperative omission of nasogastric tubes is safe and feasible, resulting in fewer rescue insertions and better postoperative outcomes compared to routine tube placement.

Imagine your body's digestive system as a bustling, high-speed train station. When food arrives, it needs to be sorted, processed, and sent on its way to different platforms without causing a jam. Sometimes, after a major renovation project at the station—like rebuilding the main tracks and switching systems—the workers worry that the trains might get stuck or arrive too fast, causing a chaotic pile-up. To prevent this, they often install a temporary "safety valve" or a drain pipe (a nasogastric tube) to suck out any extra fluid or gas, hoping to keep the pressure low and the tracks clear. This is a common practice in surgery, especially for complex operations on the pancreas, a vital organ that acts like the station's central control tower.
For years, surgeons have debated whether this safety valve is actually necessary or if it's just an old habit that might even slow down the station's recovery. Some think the tube helps; others worry it might irritate the system, making it harder for the "trains" (food) to start moving again. This question is particularly tricky when the surgery is done using tiny cameras and long tools (laparoscopy) rather than a big open cut, because the way the body reacts to the air used to inflate the belly during these minimally invasive procedures is unique. Understanding whether we can skip the tube entirely is a big deal because it could mean patients feel less pain, eat sooner, and go home faster.
This study, conducted by a team at Tongji Hospital, decided to settle the debate by looking at nearly 1,000 patients who underwent a major laparoscopic pancreatic surgery called a pancreaticoduodenectomy. The researchers grouped these patients into three different "tube strategies" to see which one worked best. The first group had the tube put in before surgery and kept in afterwards (Routine Placement). The second group had the tube in during the operation but had it pulled out before they woke up (Postoperative Omission). The third group didn't have a tube at all, not even during the surgery (Routine Omission).
The results were surprisingly clear. The team found that keeping the tube in after surgery (the Routine Placement group) didn't actually help the patients recover better. In fact, it seemed to make things harder. Patients who had the tube kept in were significantly more likely to experience a specific problem called "delayed gastric emptying," where the stomach just refuses to empty its contents properly. When the researchers looked at a score that measures the total burden of all complications a patient faces (called the Comprehensive Complication Index), the group with the tube had a much higher score, meaning they had more and worse complications overall.
On the other hand, the patients who didn't have a tube at all (Routine Omission) did just as well as, or even better than, those who had the tube removed early. They had fewer cases of the stomach getting stuck, and their overall complication scores were much lower. Interestingly, even though some people worried that skipping the tube entirely might lead to more emergencies where a tube would need to be shoved back in later, the data showed the opposite: the group with no tube at all actually needed fewer "rescue" tubes inserted later on compared to the group that had the tube removed early.
The study suggests that for this specific type of advanced, minimally invasive surgery, the old habit of keeping the tube in might be doing more harm than good. It appears that letting the body recover without the tube is safe and might even speed up the return to normal eating. While the researchers note that their study was a look back at past records and not a new experiment, the evidence strongly points toward ditching the routine tube as a smart move for patient recovery.
