Indications/Contraindications
Patients with perforated peptic ulcers usually present with acute onset of abdominal pain. Patients frequently report that the pain started “as if someone flipped a switch.” However, elderly patients frequently present with a less robust onset of pain. Occasionally, patients will complain of left shoulder pain from diaphragmatic irritation and some will complain of nausea and vomiting. While some patients report a history of recent gastritis, frequent steroid or nonsteroidal anti-inflammatory drug use, or use of cocaine, perforation may be the first clinical sign that patients have underlying peptic ulcer disease. On radiographic imaging, pneumoperitoneum is present in greater that 80% of patients.
Nonoperative management of perforated ulcers has been described since the 1940s; however, its use and patient selection remains a major debate. Patients who present with pneumoperitoneum who have a water-soluble contrast gastroduodenogram showing no extravasation, no signs of septic shock, and abdominal examination findings confined to the upper abdomen may be considered for nonoperative treatment. Nonoperative treatment routinely includes nasogastric decompression, antibiotics to cover enteric pathogens, antibiotics to cover Helicobacter pylori if present, and proton pump inhibitors. However, approximately 30% of patients treated nonoperatively do not improve and require surgical intervention. Patients treated nonoperatively also have about a 30% longer inpatient length of stay. Nonoperative management also has an extremely high failure rate (around 70%) in the elderly, patients with comorbidities, patients with hemodynamic instability, perforations greater than 48 hours old, and in patients with impaired wound healing. This creates a dilemma because the patients that you would prefer to treat nonoperatively are the ones most likely to fail nonoperative therapy. Therefore, operative treatment is the preferred modality except in an extremely selective subset of patients.
The classic indication for use of a patch for perforated ulcer is in the unstable patient with shock, the presence of extensive peritonitis or abdominal abscess formation, or patients with severe comorbidities. While patch repair of perforated ulcer was described as a damage control technique, with the development of effective medical therapy for ulcer disease and the corresponding decrease in patients requiring surgical therapy for ulcer disease, more surgeons are utilizing patch repair in the acute setting. In addition, the average age of patients presenting with perforated duodenal ulcers is increasing, with the average age now between 65 and 75 years. With this older age at presentation, it is more likely that these patients will have comorbidities that lead the surgeon to opt for a less involved procedure in the acute phase.
Preoperative Planning
While a large majority of patients do not present in hemodynamic shock, appropriate preoperative resuscitation is still needed. Placement of a nasogastric tube to decompress the stomach and limit peritoneal contamination should be performed. Antibiotics to cover enteric pathogens should be administered, along with appropriate goal-directed crystalloid resuscitation. If possible, a determination of the presence of H. pylori through a serum antibody test should be done to aid in operative planning. Urea breath tests should not be done in patients with suspected perforation. In addition, the operative plan should be decided based on the patient’s presentation. Patients who present with hemodynamic instability, signs of end-organ failure, or shock should be classified as unstable.
Gastric ulcer
Unstable patients should be treated with patch repair and biopsy of ulcer or ulcer resection depending on the location of gastric ulcer.
Patients with known H. pylori may be treated with patch repair and H. pylori eradication and biopsy.
In medication-induced ulcers, in which the medication regimen can be altered, patients may be treated with patch repair and biopsy.
Stable patients who are known to be H. pylori-negative, patients with a long history of peptic ulcer disease, or patients with essential medication needs (chronic steroid use) should undergo a definitive antiulcer procedure.
Duodenal ulcer
Unstable patients should be treated with patch repair.
Initial presentation of duodenal ulcer disease, especially if H. pylori is present, can be treated with patch repair, proton pump inhibitors, and H. pylori eradication.
Stable patients with ulcer disease refractory to proton pump inhibitors and H. pylori eradication should be treated with a definitive antiulcer procedure.
In patients who are profoundly septic, are hypotensive, or on vasopressors, one must carefully consider if a patient can tolerate pneumoperitoneum before proceeding with a laparoscopic repair. Also in patients with extensive previous abdominal surgery, significant duodenal scarring, or concomitant bleeding ulcer, the use of laparoscopy may be limited. Given the intra-abdominal inflammatory process caused by the perforation, the technique for obtaining initial intra-abdominal access may need to be modified.
Surgery
Open Technique
Patient is placed supine.
Sequential compression devices and urinary catheter are placed.
Abdomen is entered through an upper midline incision to allow for exploration of entire abdomen if gastric or duodenal perforation is not the cause of peritonitis.
Following repair of the perforation, a thorough irrigation of the abdomen with attention paid at the right and left subphrenic spaces and pelvis should be done.
The laparoscopic approach is becoming more widely used in these patients. Laparoscopy offers several advantages, most notably the magnification provided by the laparoscope, less postoperative pain, fewer postoperative pneumonias, and fewer wound
complications. Also laparoscopy affords the ability to examine the entire abdomen without extending or relocating incisions, which is especially helpful when the exact location of the perforation has not been identified preoperatively. It also aids in performing a thorough inspection and irrigation of the entire abdomen under direct visualization.
