Colonoscopic identification of a foreign body causing an hepatic abscess

Something Seems Fishy: Hepatic Abscess Due to Foreign Body Ingestion in a Pediatric Patient

Pediatric hepatic abscesses are uncommon in children. They are usually preceded by intra-abdominal infections or caused by acute or chronic biliary disease. Cases of hepatic abscesses secondary to foreign body ingestion are even rarer but are most reported in countries such as China, where ingestion of fish and chicken bones is common. We report a rare case of an adolescent patient who developed a hepatic abscess after ingestion of a fishbone foreign body. He presented to the emergency department with emesis, abdominal pain, and subjective fevers of unknown etiology. Initial imaging of the abdomen was pertinent for a heterogeneous hepatic mass with evidence of fluid collection, concerning for malignancy. Subsequent incision and drainage then confirmed fluid collection to be pus. However, his cryptogenic hepatic abscess was not responsive to broad-spectrum intravenous antibiotics. After imaging was re-reviewed and repeated, a 4.3 cm thin curvilinear hyperdensity was identified embedded in the liver parenchyma. Eventually, the patient underwent exploratory laparoscopy where a fishbone foreign body was removed. To our knowledge, this is one of the few reported pediatric cases of hepatic abscess formation caused by a foreign body ingestion. Hepatic abscesses that do not resolve with antibiotics and ultrasound-guided drainage via catheter should prompt reassessment of other uncommon etiologies, specifically migrated foreign bodies as a rare but important differential diagnosis. Compared to pyogenic hepatic abscesses, hepatic abscesses secondary to foreign bodies require expedited surgical intervention for source control; thus, timely recognition and prompt intervention are crucial to minimize morbidity and mortality.

Migrated toothpick causing a hepatic abscess with portal vein thrombosis: A case report and review of literature

Key Clinical Message

Accidental foreign body ingestion is the most common hidden cause of abdominal pain. A high index of suspicion should be implemented in patients with unresolved abdominal pain. Here we reported a 54-year-old patient with vague abdominal pain who had a successful laparoscopic removal of a toothpick.

Abstract

Toothpicks and fish bones are considered one of the most common accidentally ingested foreign bodies. Fortunately, most patients are asymptomatic. About 80%-90% of ingested foreign bodies pass through the gut spontaneously within a week. We present a case of a 54-year-old female with chronic epigastric pain and fever found to have a foreign body (toothpick) that penetrated the stomach and migrated to the liver causing liver abscess with portal vein thrombosis. The patient was managed with laparoscopic removal of the foreign body with an uneventful postoperative course.

Liver abscess caused by the ingested foreign body without sign of gastrointestinal perforation: A case report

The ingested foreign body is a very unusual etiology of liver abscess. This clinical scenario is infrequently reported in the literature. A 66-year-old male patient presented to the hospital because of abdominal pain along with 7 days of right upper quadrant pain and intermittent low-grade fever. He was living in an epidemiological area of Fasciola infection. Physical examination showed right hypochondria tenderness without guarding or rebounding. Laboratory results were significant for leukocytosis, predominant neutrophils, and increased inflammatory markers. The liver function tests were within normal limits. Abdominal ultrasonography and CT scan were consistent with a hepatic abscess spread from segment 4B to segment 3. The patient was preliminarily diagnosed with a parasitic hepatic abscess. After management with fluid infusion and antibiotics, the patient was discharged in stable condition. Two weeks later, on the follow-up visit, the patient reported intermittent low-grade fever had persisted. After consulting the CT scan, an abnormal high-attenuation linear structure was identified inside the liver lesion, which is suspected of being a foreign body. Laparoscopic surgery was performed, and a fishbone was removed from the abscess cavity. Perforation was not found in the stomach, duodenum, or in the bowel. One week later, their condition was fully resolved. Liver abscess due to a foreign body should be suspected when a patient has radiology findings suggestive of an abscess, but the clinical presentation does not indicate the common etiologies. Meticulous observation on abdominal CT scans or ultrasonography can help with diagnosis and guide treatment.

Hepatic abscess following foreign body perforation of the colon: A case report

Liver abscess following foreign body perforation of the gastrointestinal tract is uncommon. Preoperative diagnosis is challenging as the ingestion of foreign body most often goes unnoticed with non-specific presentation. We report a case of a 68-year-old male patient presenting with abdominal pain and anorexia. His investigations and cross-sectional imaging revealed a liver abscess. A colonoscopy performed to find an etiology revealed an incidental finding of a colonic perforation from an impacted denture, which was successfully removed endoscopically. Therefore, pyogenic liver abscesses remain a therapeutic challenge despite advances in imaging and therapy. The case reflects the importance of investigating for etiology of unexplained liver abscesses. The patient made an uneventful recovery following abscess drainage by image-guided pigtail stent insertion. The colonic perforation was managed conservatively.

Toothpick ingestion and migration into the liver through the colonic hepatic flexure: case presentation, management, and literature review

The approach to toothpick ingestion and its complications should not be underestimated. The surgeon should be prepared for life-threatening situations such as major vascular involvement, as well as highly specialized and technically challenging procedures, when the hepatic hilum is involved for instance. Referral to tertiary centers is sometimes mandatory.

Successful treatment of liver abscess secondary to foreign body penetration of the alimentary tract: A case report and literature review

Hepatic abscess caused by foreign body penetration of the alimentary tract is rare. We report a case of gastric antrum penetration due to a toothpick complicated by liver abscess formation. A 41-year-old man was admitted to our hospital with the chief complaint of upper abdominal pain for 2 mo. Esophagogastroduodenoscopy performed at a local clinic revealed a toothpick penetrating the gastric antrum. Computed tomography (CT) of the abdomen at our hospital revealed a gastric foreign body embedded in the posterior wall of gastric antrum with regional phlegmon over the lesser sac and adhesion to the pancreatic body without notable vascular injury, and a hepatic abscess seven cm in diameter over the left liver lobe. Endoscopic removal of the foreign body was successfully performed without complication. The liver abscess was treated with parenteral antibiotics without drainage. The patient’s recovery was uneventful. Abdominal ultrasonography demonstrated complete resolution of the hepatic abscess six months after discharge. Relevant literature from the PubMed database was reviewed and the clinical presentations, diagnostic modalities, treatment strategies and outcomes of 88 reported cases were analyzed. The results showed that only 6 patients received conservative treatment with parenteral antibiotics, while the majority underwent either image-guided abscess drainage or laparotomy. Patients receiving abscess drainage via laparotomy had a significantly shorter length of hospitalization compared with those undergoing image-guided drainage. There was no significant difference in age between those who survived and those who died, however, the latter presented to hospitals in a more critical condition than the former. The overall mortality rate was 7.95%.

Migration of two swallowed foreign bodies to different locations in the same case

Foreign body ingestion can be seen at all ages, especially in childhood. Most swallowed foreign objects are disposed from the body without any health problems through defecation. It is rare that a foreign object perforates the intestine and migrates into the liver or peritoneum. In our case two unintentionally swallowed needles pierced the intestine and were located in the left lobe of the liver and small intestine mesentery. Foreign objects were detected in the abdomen of a 20-year-old female patient during examination performed for abdominal pain that lasted for three months. After a follow up period of three weeks the patient's complaints continued. She underwent laparotomy and both needles were removed in one session. It should be kept in mind that swallowed foreign objects can sometimes perforate the gastrointestinal system and may be located in different organs in the abdomen.

Liver Abscess following Hematogenous Transmission due to Rectal Foreign Body Perforation

Liver abscess caused by hematogenous transmission from a gastrointestinal perforation by a foreign body is a rare but life-threatening condition. We present the case of a 57-year-old male with a pyogenic liver abscess generated on the basis of a foreign body perforation of the rectum. This has not been reported previously. During the examination of the patient, computed tomography scan showed not only the liver abscess but also an inflammatory presacral process, which communicated with the rectum through a 6.5-cm-long foreign body. Subsequent sigmoidoscopy showed a toothpick placed transmurally in the rectum; the toothpick was removed endoscopically. We discuss the importance of computed tomography scans and colonoscopies in relation to liver abscesses of unknown etiology, including the importance of detecting possible perforation caused by possible foreign bodies, polyps or cancer.

Liver abscess caused by toothpick and treated by laparoscopic left hepatic resection: case report and literature review

Hepatic abscesses caused by ingested foreign bodies have been reported in the medical literature but represent very uncommon events. Extra-luminal migration of sawing needles and pins is the most common cause of perforation of the gastrointestinal tract associated with liver infections. Other non-metallic sharp objects such as animal bones and toothpicks have been described but are less frequent. The authors present a case of a 45-year-old woman who suffered from sepsis and a liver abscess because of the migration of a toothpick that lodged in the left hepatic lobe. Review of the literature on the pathogenesis and clinical management of liver abscesses caused by ingested foreign is presented.

An unusual zoonosis: liver abscess secondary to asymptomatic colonic foreign body

A liver abscess may arise following any insult to gut integrity allowing portal drainage of bacteria to hepatocytes. Foreign bodies such as bones, toothpicks and items of stationery have previously been implicated in compromising gut epithelium. Here we present the case of a 57 year old man suffering from a left liver abscess. This was defined on CT which incidentally also identified a chicken bone protruding through the wall of the distal sigmoid colon. Whilst unwell with upper abdominal pain and sepsis, the presumed source of portal sepsis within the colon remained asymptomatic throughout. Following percutaneous drainage, the liver abscess resolved but the chicken bone had not passed at two months, necessitating atraumatic removal at colonoscopy. A high rate of incidental diagnoses suggests that unidentified foreign bodies may be vastly under recognised in cases of hepatic sepsis. Thus, identification of the precise mechanism of the liver insult demands thorough consideration; foreign body should be considered in all cases.

Pyogenic liver abscess: differences in etiology and treatment in Southeast Asia and Central Europe

Knowledge of etiology and timely treatment of underlying causes, when possible, play an important role in the successful therapy of patients with pyogenic liver abscess (PLA). Recent publications from Central Europe and Southeast Asia hint at considerable differences in etiology. In this article, we aim to elaborate these differences and their therapeutic implications. Apart from some special types of PLA that are comparable in Southeast Asia and Central Europe (such as posttraumatic or postprocedural PLA), there are clear differences in the microbiological spectrum, which implies different risk factors and disease courses. Klebsiella pneumoniae (K. pneumoniae) PLA is predominantly seen in Southeast Asia, whereas, in Central Europe, PLA is typically caused by Escherichia coli, Streptococcus or Staphylococcus, and these patients are more likely to be older and to have a biliary abnormality or malignancy. K. pneumoniae patients are more likely to have diabetes mellitus. Control of septic spread is crucial in K. pneumoniae patients, whereas treatment of the underlying diseases is decisive in many Central European PLA patients.

Hepatic abscess that formed secondary to fish bone and had a fistula with the ascending colon

We present the case of a liver abscess that formed secondary to foreign bodies and formed a fistula the ascending colon and was successfully treated with percutaneous abscess drainage and colonoscopic removal of foreign bodies. A 64-year-old man presented with right upper and lower quadrant pain of 2 weeks' duration. Abdominal computed tomography was performed, demonstrating a single 3.5 x 1.9-cm abscess of the liver's right lobe and eccentric thickening of the colon wall at hepatic flexure. A percutaneous hepatic drainage catheter was placed under ultrasound guidance. Colonoscopic examination revealed multiple diverticula of the ascending colon and two 1.5-cm long fish bones at the ascending colon near the hepatic flexure. One end of each fish bone had impacted the edematous colonic mucosa and was surrounded by exudate polypoid inflammatory tissue. The fish bones were extracted with forceps. The patient was feeling well and was discharged after 12 days of treatment.

Hepatic abscess secondary to a rosemary twig migrating from the stomach into the liver

The ingestion of a foreign body that penetrates the gastric wall and migrates to the liver, where it causes an abscess is uncommon. A case of an ingested rosemary twig perforating the gastric antrum, then migrating to the liver, complicated by hepatic abscess and Staphylococcus aureus sepsis is reported. A 59-year-old man without a history of foreign body ingestion was admitted to our hospital because of sepsis and epigastralgia, which had progressively worsened. No foreign body was identified at preoperative imaging, but a rosemary twig was discovered during laparotomy. The liver abscess and sepsis were controlled successfully with surgery and antibiotics. This unusual condition should be kept in mind when dealing with cases of hepatic abscess, or even sepsis of unknown origin. Despite the improvement of non-surgical techniques such as percutaneous drainage and interventional endoscopy, surgery still remains important in the treatment of hepatic abscess caused by an ingested foreign body.

Hepatic abscess induced by foreign body: Case report and literature review

Hepatic abscess due to perforation of the gastrointestinal tract caused by ingested foreign bodies is uncommon. Pre-operative diagnosis is difficult as patients are often unaware of the foreign body ingestion and symptoms and imagiology are usually non-specific. The authors report a case of 62-year-old woman who was admitted with fever and abdominal pain. Further investigation revealed hepatic abscess, without resolution despite antibiotic therapy. A liver abscess resulting from perforation and intra-hepatic migration of a bone coming from the pilorum was diagnosed by surgery. The literature concerning foreign body-induced perforation of the gastrointestinal tract complicated by liver abscess is reviewed.

Hepatic abscess secondary to foreign body perforation of the stomach

Foreign body penetration of the stomach is seldom encountered in general surgical practice. Liver abscess as a consequence of such occurrence has only been reported sporadically. We report three cases of liver abscesses due to direct penetration injury of the stomach by ingested foreign bodies. All three patients presented with clinical features of liver abscess without history of foreign body ingestion. All recovered with surgical treatment. Successful management relies on prompt recognition and early intervention as deaths have been reported due to missed or delayed diagnosis. The potential role of a minimally invasive approach in the management of this entity is also discussed.

Treatment of patients with pyogenic liver abscess

BACKGROUND

Pyogenic liver abscess (PLA) remains a serious disease with a mortality of 6-14%.

METHODS

Clinical data of 76 patients with PLA were analyzed. Treatment options comprised antibiotics, percutaneous puncture/drainage, endoscopic papillotomy/stenting and/or surgery as indicated.

RESULTS

Fifty-eight patients (76%) had single and 18 patients multiple PLA (right lobe: 65%; both lobes: 22%). The most frequent etiologies were: biliary (38%), hematogenous and posttraumatic (11%). Factors associated with the need for surgery included gallbladder empyema, biliary fistulas, malignancy, perforation, multicentricity, vascular complications and foreign bodies (e.g. infected ventriculo-peritoneal shunt, toothpick).

CONCLUSIONS

Microbiological testing provides important information for treatment monitoring and modification. Complementary assessment of risk factors for a complicated course is crucial for timely identification of patients requiring additional treatment.
