Liver abscess in the caudate lobe caused by a fishbone and treated by laparoscopy: a case report

Background Ingestion of fish bones leading to gastric perforation and inducing abscess formation in the caudate lobe of the liver is very rare. Case presentation A 67-year-old man presented to our hospital with a 2-day history of subxiphoid pain. There were no specific symptoms other than pain. Laboratory tests showed only an increase in the number and percentage of neutrophils. Contrast-enhanced Computerized tomography (CT) of the abdomen showed two linear dense opacities in the gastric cardia, one of which penetrated the stomach and was adjacent to the caudate lobe of the liver, with inflammatory changes in the caudate lobe. We finally diagnosed his condition as a caudate lobe abscess secondary to intestinal perforation caused by a fishbone based on the history and imaging findings. The patient underwent 3D laparoscopic partial caudate lobectomy, incision and drainage of the liver abscess, and fishbone removal. The procedure was successful and we removed the fishbone from the liver. The patient was discharged on the 9th postoperative day without other complications. Conclusions Liver abscess caused by foreign bodies requires multidisciplinary treatment. Especially when located in the caudate lobe, we must detect and remove the cause of the abscess as early as possible. Foreign bodies that perforate the gastrointestinal tract can penetrate to the liver and cause abscess formation, as in this case. When exploring the etiology of liver abscesses, we should investigate the general condition, including the whole gastrointestinal tract.

Association of ileocolic pedicle division with postoperative complications after restorative proctocolectomy and ileal pouch-anal anastomosis for ulcerative colitis

Background When performing a restorative proctocolectomy (RPC) with an ileal pouch-anal anastomosis (IPAA), it is common practice to divide the ileocolic artery (ICA) if the patient has a tumor or dysplasia, or in order to gain sufficient length to secure a tension-free anastomosis. However, it is unclear whether there is an association between division of the ICA and the rate of postoperative complications. Methods We retrospectively analysed all patients with ulcerative colitis who underwent RPC and IPAA in our department between January 2010 and December 2016. These were divided in two groups, with regard to the ICA being preserved (PRE group) or divided (DIV group). Complications such as stenosis or leakage of the IPAA, perianal fistulas, abscess formation within the lesser pelvis and pouchitis were analysed and compared between both groups. Results We identified 130 patients meeting the study inclusion criteria, 49 patients in the PRE and 81 patients in the DIV group. No statistical significance was observed in IPAA leakages (p = 0.71), anastomotic strictures (p = 0.33), fistulas (p = 0.19) and pouchitis (p = 0.72). Abscess formation frequency was similar in both groups (p > 0.99). Moreover, short-term (p = 0.53) and long-term complications (p = 0.11) were similar in both groups. A higher conversion rate was observed in obese (p = 0.006) and male (p = 0.02) patients. Within the entire study population, fistulas and IPAA leakages were associated with a higher rate of anastomotic strictures (p = 0.008 and p = 0.02 respectively). Conclusion Our data suggest similar IPAA related complications after either division or preservation of the ICA. Further trials are required in order to examine the trends observed in this study.

Clinical and Microbiological Factors Associated With Abscess Formation in Adult Acute Epiglottitis

Objectives: To evaluate clinical and microbiological findings that are correlated with abscess formation in adult acute epiglottitis (AE). Methods: We reviewed 140 cases of adult AE. Demographic, clinical, imaging, and microbiological findings are analyzed for all patients with AE in comparison to those with epiglottic abscess (EA). Results: A total of 113 patients presented with AE and 27 presented or progressed to EA (19.3%). Age, sex, seasonality, smoking, body mass index (BMI), and comorbidities were statistically insignificant between the 2 groups. Muffled voice ( P < .013), respiratory distress ( P < .001), and pre-existence of epiglottic cyst ( P < .001) are symptoms and signs connected with abscess formation. A total of 120 patients were treated conservatively. Surgical treatment was performed on 20 patients with EA. About 72 out of 80 cultures revealed monomicrobial infection. Mixed flora was isolated in 8 patients with EA. Streptococcus was isolated in 51 out of 80 positive cultures (64%). Haemophilus Influenza ( Hib) was not isolated in any sample. EA and mixed flora relates to a higher rate of airway intervention ( P < .001). Conclusion: A high level of suspicion for abscess formation is required if clinical examination reveals dyspnea, muffled voice, or an epiglottic cyst in adult with AE. The existence of EA doubles the duration of hospitalization. EA is typically found on the lingual surface of the epiglottis. Supraglottic or deep neck space expansion should be treated surgically. EA is associated with a mixed flora and a higher rate of airway obstruction. Streptococcus is discovered to be the most common pathogen.

Rathke’s Cleft Cyst Abscess—An Unusual Guest in The Sella

Abscess formation within a Rathkes’s cleft cyst (RCC) is extremely rare, particularly at a young age. We report the case of a young girl with abscess formation in RCC. A 21-year-old female presented with headache, vomiting, visual deterioration and features suggestive of hypopituitarism. She had bitemporal hemianopia with impairment of visual acuity. MRI revealed a cystic lesion in the sella with suprasellar extension and peripheral rim enhancement. On the basis of history and imaging, this was indistinguishable from more commonly encountered pituitary pathology. She underwent transsphenoidal decompression, which revealed yellowish purulent material that when cultured grew Staphylococcus epidermidis. Histological examination revealed numerous neutrophils and cyst wall lining with features characteristic of RCC. Postoperatively, she received antibiotics and replacement therapy for hypopituitarism. Three months later, she experienced deterioration in visual fields. Considering persistent disease, she underwent redo surgery which revealed similar findings. Postsurgery, pituitary MRI revealed an empty sella syndrome. Thereafter, follow-up for 1 year was stable with permanent diabetes insipidus and multiple pituitary hormone deficiency on supplementation. Although uncommon, we recommend considering RCC abscess as a differential diagnosis of a pituitary mass lesion, as predicting its presence can be difficult preoperatively. Persistent or recurrent disease is common in these cases, so timely diagnosis and adequate surgical drainage leads to lower morbidity and mortality.

Liver abscess after drug-eluting bead chemoembolization in patients with metastatic hepatic tumors

Objective: To investigate the incidence and risk factors for liver abscess formation after treatment with drug-eluting bead chemoembolization (DEB-TACE) in patients with metastatic hepatic tumors (MHT). Methods: The current study is a retrospective analysis of the clinical data of 137 patients with metastatic hepatic tumors who received DEB-TACE treatment in our institute between June 2015 and September 2020. Patients were evaluated for the presence or absence of post-DEB-TACE liver abscess. Univariate and multivariate analyses were used to identify risk factors for liver abscess formation. Results: The incidence of liver abscess formation after the DEB-TACE procedure was 8.76% per patient and 5.53% per procedure. Univariate analysis showed that larger maximum tumor diameter (p = 0.004), Grade one artery occlusion (p < 0.001) and systemic chemotherapy within 3 months before the DEB-TACE procedure (p < 0.001) were all associated with liver abscess formation. However, only systemic chemotherapy within 3 months before the DEB-TACE procedure (OR 5.49; 95% CI 0.34–13.54; p < 0.001) was identified by multivariate analysis to be an independent risk factor. Conclusions: Tumor size, Grade one artery occlusion and recent systemic chemotherapy may all be associated with increased risk of liver abscess formation following DEB-TACE treatment in patients with metastatic hepatic tumors. Advances in knowledge: Identification of risk factors for liver abscess formation following DEB-TACE in patients with MHT. These findings suggest the need for caution and consideration of the aforementioned risk factors on the part of interventional radiologists when designing DEB-TACE strategies and performing post-procedure patient management.
