Context: Advance the seeking catheter over the wire guide, then use the seeking catheter and wire guide as a unit to advance into the jejunum.
Remove the seeking catheter, leaving the wire guide in place.
Dilate the tract through the abdominal wall by advancing the supplied dilators, in sequential order, over the wire guide.
Question: Does the "tract" mean the gastrointestinal tract? Besides, why it is dilated "through the abdominal wall"?
Thank you in advance!

Could it possible be a "needle tract"..

Laparoscopic Insertion of Gastrostomy and Jejunostomy Feeding Tubes[14]
When PEG is contraindicated in situations like oesophageal malignancy, gross obesity (with poor transabdominal transillumination with gastroscope), and ascites, feeding gastrostomy or jejunostomy are performed by open surgery. Recently, techniques have been developed for laparoscopic insertion of gastrostomy and jejunostomy feeding tubes.
During laparoscopy the jejunum is first anchored to the posterior abdominal wall with the help of sutures. The jejunostomy tube is inserted using the Seldinger technique and using a standard introducer and peel-away sheath kit. A needle is introduced percutaneously into the jejunum and a guidewire is then passed through the needle. The tract is dilated over the guidewire with a 12 Fr dilator and sheath. The dilator is removed and a 10 Fr catheter is inserted through the sheath. The sheath is then peeled away leaving the feeding tube in the jejunum. The tube feeding can be started in the immediate post-operative period.
The technique for gastrostomy insertion is essentially identical except that a larger(18 Fr) balloon-tipped catheter is used.

: in The Image you can see they have made the track hole wider (Dilated) to allow for the next dilator (hole expander) to advance through the hole
