From the Guidelines
After a pyloromyotomy, patients should be initiated on normal food intake or enteral feeding early, with oral intake adapted to individual tolerance and the type of surgery carried out, as recommended by the ESPEN guidelines on enteral nutrition 1. The goal is to advance to full-strength formula or breast milk over 24-48 hours as tolerated, with close monitoring for vomiting, which may occur initially but should decrease in frequency and volume.
- Key points to consider post-operatively include:
- Initiating oral intake, including clear liquids, within hours after surgery, as this can be tolerated by most patients undergoing gastrointestinal surgery 1.
- Adapting oral intake to individual tolerance, taking into account the type of surgery performed.
- Considering tube feeding in patients who cannot initiate early oral nutrition, particularly those with severe trauma, obvious undernutrition, or inadequate oral intake expected to last more than 10 days 1.
- Post-operative care also involves:
- Keeping the incision clean and dry, with regular dressing changes as instructed, and watching for signs of infection such as redness, swelling, or drainage.
- Managing pain with acetaminophen (10-15 mg/kg every 4-6 hours) or ibuprofen (5-10 mg/kg every 6-8 hours) as needed.
- Gradually resuming normal activities, avoiding strenuous activity for 2-3 weeks.
- Scheduling follow-up with the surgeon for 1-2 weeks post-surgery to assess recovery and address any concerns. These instructions prioritize the patient's recovery, nutrition, and hydration, aiming to minimize complications and ensure the best possible outcome after pyloromyotomy, in line with the principles outlined in the ESPEN guidelines on enteral nutrition 1.
From the Research
Post-Operative Instructions for Pyloromyotomy
The following instructions are based on studies related to post-operative care for patients after pyloromyotomy:
- Wound Care: There is no significant decrease in wound infection rate with the use of prophylactic antibiotics after laparoscopic pyloromyotomy 2. However, mass closure with polydioxanone is associated with a lower wound sepsis rate 3.
- Emesis Management: Oral atropine can be used to treat persistent emesis after pyloromyotomy, reducing the need for a second operation due to incomplete pyloromyotomy 4.
- Feeding: A standardized postoperative care protocol can result in fewer patients with prolonged postoperative length of stay, shorter time to feeds, and fewer feeds to discharge 5.
- Pain Management: Laparoscopic pyloromyotomy can result in less analgesic requirement compared to open pyloromyotomy 6.
- Follow-Up: Patients should be followed up to monitor for any complications, such as wound infections or incomplete pyloromyotomy 2, 4, 6.
Complications
Possible complications after pyloromyotomy include:
- Wound infections 2, 3
- Incomplete pyloromyotomy 4
- Mucosal perforations 4
- Duodenal perforations 4
- Incisional hernias 4
- Apnea requiring reintubation 4
Surgical Approach
The choice of surgical approach (open, laparoscopic, or umbilical) can affect the outcome of pyloromyotomy, with laparoscopic pyloromyotomy resulting in fewer episodes of emesis and less analgesic requirement 6.
