Perforation of colon by ingested chicken bone diagnosed by colonoscope

Unusual Presentation of a Sigmoid Mass with Chicken Bone Impaction in the Setting of Metastatic Lung Cancer

Background

Ingestion of foreign bodies can cause various gastrointestinal tract complications including abscess formation, bowel obstruction, fistulae, haemorrhage, and perforation. While these foreign body-related complications can occur in normal bowel, diseased bowel from inflammation, strictures, or malignancy can cause diagnostic difficulties. Endoscopy is useful in visualising the bowel from within, providing views of the mucosa and malignancies arising from here, but its ability in diagnosing extramural malignancies arising beyond or external to the mucosa of the bowel as in the case of metastatic extramural disease can be limited.

Case Summary

We present the case of a 60-year-old female with an impacted chicken bone in the sigmoid colon with formation of a sigmoid mass, on a background of metastatic lung cancer. On initial diagnosis of her lung cancer, there was mild Positron Emission Tomography (PET) avidity in the sigmoid colon which had been evaluated earlier in the year with a colonoscopy with findings of diverticular disease. Subsequent computed tomography (CT) scans demonstrated thickening of the sigmoid colon with a structure consistent with a foreign body distal to this colonic thickening. A repeat PET scan revealed an intensely fluorodeoxyglucose (FDG) avid mass in the sigmoid colon which was thought to be inflammatory. She was admitted for a flexible sigmoidoscopy and removal of the foreign body which was an impacted chicken bone. She had a fall and suffered a fractured hip. During her admission for her hip fracture, she had an exacerbation of her abdominal pain. She developed a large bowel obstruction, requiring laparotomy and Hartmann's procedure to resect the sigmoid mass. Histopathology confirmed metastatic lung cancer to the sigmoid colon.

Conclusion

This unusual presentation highlights the challenges of diagnosing ingested foreign bodies in patients with metastatic disease.

Diverticular Perforation Secondary to a Chicken Bone: Food for Thought

A 56-year-old man presented to the emergency department with a one-day history of lower abdominal pain and fever. Clinical examination revealed generalized peritonitis. A computed tomography (CT) scan identified a linear hyperdensity straddling the site of a perforated sigmoid diverticulum. The patient proceeded to emergency laparotomy, which confirmed feculent peritonitis secondary to chicken bone perforation through the sigmoid colon diverticulum. After removal of the bone, Hartmann’s procedure was performed, and the patient subsequently made an excellent recovery.

Colon perforation caused by swallowing a shrimp leg: A case report

•

Colon perforation caused by swallowing a shrimp leg is the first reported case currently.

•

Chronic perforation of colon may not need emergent surgery.

•

Laparoscopic drainage and removal of shrimp leg is effect treatment to diminish hospital days.

Introduction

Ingestion of a foreign body rarely results in perforation of the gastrointestinal tract. Foreign bodies such as dentures, fish bones, chicken bones, toothpicks and cocktail sticks have been known to cause bowel perforation; however, bowel perforation caused by shrimp leg has not been reported so far.

Presentation of case

We report a case of a 69-years-old man who presented with a 4-months epigastric pain. Laboratory data revealed inflammation at the first hospital visit. Computed tomography revealed a hypodense lesion containing a hyperdense foreign body in the abdomen. Intra-abdominal abscess caused by foreign body perforation was diagnosed.

Discussion

An increased incidence of perforation has been reported in association with Meckel’s diverticulum, the appendix, and diverticular disease. The abdominal abscess in this case was located beside the diverticulum of transverse colon, so the perforation most likely occurred in the diverticulum of transverse colon.

Conclusion

Perforation of colon by shrimp leg is very rare and not reported currently. Although some cases have been successfully treated chronic foreign-body perforation with abscess by using antibiotics alone, typical treatments remains surgical drainage of the abscess and removal of foreign body.

Foreign bodies in sigmoid colon diverticulosis

This review addresses the management of sigmoid colon diverticular disease associated with foreign bodies. In addition, two novel cases are presented. One case describes the management of diverticular bleeding secondary to a chicken bone and the other case reports retrieval of a retained EndoRings™ Device. The review identified 40 relevant publications including 50 subjects. Foreign bodies within sigmoid diverticular disease may be associated with inflammation, perforation, abscess and fistula. In current practice, diagnosis is often achieved with CT scan. Patients with colonic perforation or fistula generally require colonic resection. Patients with inflammation may merit conservative management, including colonoscopic foreign body retrieval. Chicken bones, tooth picks, and biliary stents have been reported in patients with inflammation, perforation and fistula, whereas all published patients with fish bone related diverticulosis complications experienced inflammation. Treatment might be best guided by the consequences of the foreign body rather than the nature of the underlying retained object. Diverticular bleeding secondary to a chicken bone was diagnosed at CT angiography and treated with colonoscopic snare retrieval of the bone and clipping of the bleeding diverticulum. The EndoRings™ Device was retrieved with a colonoscopic balloon.

Successfully treated intra-abdominal abscess caused by fish bone with perforation of ascending colon: a case report

Ingestion of a foreign body is not uncommon, but rarely results in perforation of the gastrointestinal tract. The most common sites of perforation are reportedly the narrowest parts of the bowel, and perforation of the right side of the colon is rare. We report herein the case of a 69-year-old man who presented with an 8-week history of right upper abdominal pain. Laboratory data revealed inflammation at the first hospital visit. Computed tomography revealed a hypodense lesion containing a hyperdense foreign body in the abdomen. Intra-abdominal abscess caused by foreign body perforation was diagnosed. After administering antibiotics for 2 weeks, surgery was performed. Symptoms had resulted from perforation of the ascending colon by a fish bone.

Fish bone migration to the urinary bladder after rectosigmoid colon perforation

Fish bones are the most common foreign objects leading to bowel perforation. Most cases are confined to the extraluminal space without penetration of an adjacent organ. However, abscess formation due to the perforation of the rectosigmoid colon by a fish bone can lead to the penetration of the urinary bladder and may subsequently cause the fish bone to migrate into the urinary bladder. In the presented case, a 42-year-old female was admitted for lower abdominal pain. The computed tomography (CT) demonstrated a 5cm pelvic abscess containing a thin and curvilinear foreign body. After conservative management, the patient was discharged. After 1 mo, the subject developed a mechanical ileus. Surgery had to be delayed due to her hyperthyroidism. Migration of the foreign body to the urinary bladder was shown on additional CT. A Yellowish fish bone 3.5 cm in size was removed through intra-operative cystoscopy. The patient was discharged 8 d after the operation without any unexpected event.

Perforation of the transverse colon by a fish bone: a case report

The inadvertent swallowing of foreign bodies is common, but rarely results in perforation of the gastrointestinal tract. Because any site of the gastrointestinal tract may be perforated by a foreign body, the clinical presentation may vary and mimic diverse medical conditions. We report the case of a 60-year-old man who experienced left upper quadrant pain of 4 weeks duration before the onset of peritoneal signs. The symptoms were shown to result from perforation of the transverse colon by a fish bone (35 mm in length) with a developing abscess.
