Effect of Press Needle Therapy on Gastrointestinal Function After Laparoscopic Radical Distal Gastrectomy: A Retrospective Cohort Study
This retrospective cohort study demonstrates that press needle therapy, particularly when augmented with auxiliary acupoints like LI4 or SP6, significantly accelerates gastrointestinal recovery, reduces inflammation, and alleviates pain in patients undergoing laparoscopic radical distal gastrectomy compared to standard treatment.

Imagine your body as a bustling city. After a major construction project, like a new highway being built inside a building, the city's traffic lights and delivery trucks often get confused. The roads are clear, but the trucks (your food and waste) just sit in the depot, refusing to move. In the medical world, this is called "postoperative ileus," a common hiccup after stomach surgery where the gut goes on strike, leaving patients feeling bloated, nauseous, and stuck in the hospital longer than necessary. While doctors have tried various chemical "traffic controllers" to get things moving again, they haven't always worked perfectly. This is where the ancient art of acupuncture steps in, acting like a skilled traffic manager who knows exactly which buttons to press to restart the flow. But traditional acupuncture can be tricky—it requires precise needle insertion and can be scary for some. Enter "press needle therapy," a gentler, modern twist where tiny, harmless pins are taped to the skin and pressed gently, acting like a continuous, low-volume reminder to the body's internal systems to wake up and get back to work.
This study, conducted by researchers at Ningbo University, decided to put this gentle "traffic management" to the test. They looked back at the records of 193 patients who had undergone a specific type of stomach cancer surgery called a laparoscopic radical distal gastrectomy between January 2022 and March 2025. The researchers wanted to see if taping these tiny press needles to specific points on the body could help the gut start working again faster than standard care alone. They didn't just test one combination; they played a bit of a "recipe game," comparing a basic two-point recipe against two upgraded versions that added a third point, to see if more points meant a faster recovery.
The results were quite clear: the press needle therapy worked. Compared to the group that received only standard hospital care, every group that got the press needles saw their guts start making noise (bowel sounds) much sooner. The basic recipe, which used two famous points known as Zusanli (ST36) and Neiguan (PC6), shaved off an average of 8.58 hours from the wait time. But the researchers found that adding a third point made the effect even stronger. The group with the three-point recipe (ST36-PC6-LI4) recovered about 5.04 hours faster than the basic two-point group, while the other three-point group (ST36-PC6-SP6) was about 6.02 hours faster. Interestingly, the two upgraded recipes were almost identical in how fast they got the gut moving, but the one with the extra point called Hegu (LI4) seemed to be a better "pain reliever," helping patients feel less discomfort in the first day after surgery.
Beyond just getting the gut moving, the therapy seemed to calm the body's internal alarm system. Patients who received the press needles had lower levels of inflammation markers (specifically CRP and IL-6) 72 hours after surgery and reported less pain. The study suggests that these tiny, taped-on needles act as a simple, effective way to jumpstart the digestive system after major surgery. While the researchers note that their study was a look back at past records (which means they can't prove cause-and-effect as strongly as a future experiment could), the data strongly suggests that adding these specific acupoints to the treatment plan is a smart move. It turns out that sometimes, the best way to get a city's traffic flowing again isn't a loud siren, but a gentle, persistent tap on the right buttons.
