Abstract

Perforation of the gastrointestinal tract due to ingested foreign bodies may manifest itself with different clinical signs or symptoms and correct diagnosis is rarely performed before the operation. In our case, we detected a perforation due to foreign body (chicken bone) without strangulation in a patient who was operated with the preliminary diagnosis of small intestinal perforation secondary to incisional hernia. It should be kept in mind that a possible foreign body inside the incarcerated bowel segment can cause ulceration and perforation in the bowel wall if it cannot progress due to the angulation occurring in the tract. The computed tomography scans of the patients should be interpreted with caution since there may be a foreign body within the herniated area.

Introduction

A large proportion of ingested impurities are usually excreted out of the gastrointestinal tract spontaneously without causing any problems. Small bowel perforation due to foreign bodies is a rare clinical finding and occurs in less than 1% of patients 1.As swallowing a foreign body is often accidental, it is difficult to diagnose. Intentionally swallowing a foreign body is more frequently seen in psychiatric patients 2. However, in a small proportion of patients who ingest foreign bodies, complications such as perforation or ileus due to impaction may develop 3,4. A 65-year-old male patient with incarceration due to the intestinal perforation who was operated with the diagnosis of aforeignbody attachment  (chicken bone) without strangulation is presented.

Case Report

A 65-year-old male patient presented to the emergency department with complaints of aggravated pain and nausea and vomiting after sudden onset of abdominal pain. Patient had a history of incisional hernia due to ileus-related colon resection and follow-ups. It was learned that there was swelling in the incision area for about 2 years. The patient's vital signs were 38.2 ° C fever, 110 / min heart rate, and 25 / minute breathing. The patient with tachycardia, tachypneia and fever,  had tenderness, defenses and rebound in the abdominal examination, especially in the region that had muscle-fascia defect in the incision area. Intestinal loops in the hernia area were incarcerated and could not be reduced. White blood cell count was 13.026x103 ,L, CRP: 32.2 mg / dl and Hgb: 12.7 g / dl. Biochemistry values were within normal limits. In the abdominal computed tomography of the patient with intravenous contrast, an abdominal obstruction was seen at the superior surface of the umbilicus at the 2 sides of the abdominal wall and the hernia under the skin was observed. Correlated doppler showed strangulated herniated bowel loops in ultrasound examination and free air and fluid values ​​were observed in the abdomen. The patient was thought to have perforated strangulated bowel and was decided that he should undergo an  emergency surgical exploration. In the exploration, purulent fluid and diffuse adhesions were observed inside the hernia sac and in the abdomen. There was perforation in the bowel of the hernia. In this area, a foreign body was seen as a chicken bone (Figure 1).

It was decided that the perforation in the bowel was due to the foreign body. After the perforated area was resected, it was repaired by side-to-side with anastomosis. The hernia defect was repaired primarily without patching. Postoperatively, when the patient's abdominal computed tomography was taken to the emergency department, a foreign body was observed in herniated area (Figure 2).

The patient was discharged from the hospital on the 8th postoperative day after gradual regeneration of the regimen due to the lack of significant return from the drains on the postoperative 5th day.

Discussion

It is defined as herniation of the organs of the gastrointestinal tract out of the abdominal compartment. This condition can cause normal anatomy to be impaired by decreasing blood supply and narrowing of the gastrointestinal tract and slowing the passage 6. Inadvertent swallowing of foreign bodies is common in childhood, but can be seen in all age groups. It is an emergency condition especially in adults with psychiatric disorders 2. The most important result of this condition is gastrointestinal perforation. The most common cause of perforation of the gastrointestinal tract is swallowing foreign bodies like  fish bones, chicken bones, and sharp objects such as toothpicks 1,3. Complications due to foreign body ingestion may not be diagnosed by routine physical examination and standard diagnostic methods. Patients may present with localized or extensive peritonitis, abdominal mass or abscess 2. The most common radiological finding is free air in  the abdomen after perforation, ileus and acute abdomen 2.

Sometimes foreign bodies can progress through the intestinal tract and can  be removed by defecation. However, during normal progression, they may cause ulceration or perforation if they coincide with  narrowed areas such as secondary to herniation 5. In our case, the patient developed an acute abdomen due to the fact that the chicken bone that he swallowed without noticing  could not progress in the narrowed area of the bowel segments within the existing incarcerated hernia sac, and perforated the area.

In conclusion, the reason of perforation in  patients with acute abdominal pain is not always strangulation. It should be kept in mind that a possible foreign body in the incarcerated bowel segment can cause ulceration and perforation in the bowel wall if it cannot progress due to the angulation occurring in the tract. The computed tomography scans of the patients, should be interpreted with caution since it may be a foreign body within the herniated area.
