Multiple pyogenic liver abscess

Blood purification for treatment of non-liquefied multiple liver abscesses and improvement of T-cell function: A case report

BACKGROUND

Non-liquefied multiple liver abscesses (NMLA) can induce sepsis, septic shock, sepsis-associated kidney injury (SA-AKI), and multiple organ failure. The inability to perform ultrasound-guided puncture and drainage to eradicate the primary disease may allow for the persistence of bacterial endotoxins and endogenous cytokines, exacerbating organ damage, and potentially causing immunosuppression and T-cell exhaustion. Therefore, the search for additional effective treatments that complement antibiotic therapy is of great importance.

CASE SUMMARY

A 45-year-old critically ill female patient presented to our hospital's intensive care unit with intermittent vomiting, diarrhea, and decreased urine output. The patient exhibited a temperature of 37.8 °C. Based on the results of liver ultrasonography, laboratory tests, fever, and oliguria, the patient was diagnosed with NMLA, sepsis, SA-AKI, and immunosuppression. We administered antibiotic therapy, entire care, continuous renal replacement therapy (CRRT) with an M100 hemofilter, and hemoperfusion (HP) with an HA380 hemofilter. The aforementioned treatment resulted in a substantial reduction in disease severity scores and a decrease in the extent of infection and inflammatory factors. In addition, the treatment stimulated the expansion of the cluster of differentiation 8+ (CD8+) T-cells and led to the complete recovery of renal function. The patient was discharged from the hospital. During the follow-up period of 28 d, she recovered successfully.

CONCLUSION

Based on the entire therapeutic regimen, the early combination of CRRT and HP therapy may control sepsis caused by NMLA and help control infections, reduce inflammatory responses, and improve CD8+ T-cell immune function.

A case of transverse colon cancer with a large liver abscess that could be treated with a radical operation after infection control

INTRODUCTION

Advanced colorectal cancer is known to be associated with liver abscesses. A strategy to treat liver abscesses as early as possible is necessary to ensure high surgical curability before the cancer progresses and to prevent worsening nutritional status of the patient during surgery.

PRESENTATION OF CASE

An 82-year-old woman was hospitalized due to fever. A 10 cm in diameter liver abscess and advanced colon cancer were diagnosed. After conservative treatment of the liver abscess with antibiotics and puncture drainage, colorectal cancer surgery was performed on a standby basis.

DISCUSSION

We propose that empiric antibiotic therapy should be administered early in cases of liver abscesses that may require early colorectal surgery. Abscess drainage should be performed promptly if the abscess is of a size that can be punctured easily.

CONCLUSION

In patients with advanced colorectal cancer complicated by liver abscesses that required early surgery, prompt drainage of the liver abscesses is mandatory.

Minimally Invasive Surgical Management as Effective First-Line Treatment of Large Pyogenic Hepatic Abscesses

Management of pyogenic hepatic abscesses (PHA) varies among surgeons and institutions. Recent studies have advocated for first-line percutaneous drainage (PD) of all accessible hepatic abscesses, with surgery reserved as rescue only. Our study aimed to internally validate an established multimodal algorithm for PHA at a high-volume hepatopancreatobiliary center. Patients treated by the hepatopancreatobiliary service for PHA were retrospectively reviewed from 2008 through 2018. The algorithm defined intended first-line treatment as antibiotics for type I abscesses (<3 cm), PD for type II (≥3, unilocular), and surgical intervention (minimally invasive drainage or resection, when possible) for type III (≥3 cm, multilocular). Outcomes were compared between patients who received first-line treatment following the algorithm versus alternate therapy. Of 330 patients with PHA, 201 met inclusion criteria. Type III abscesses had significantly lower failure following algorithmic approach with surgery compared with PD (4% vs 28%, P = 0.018). Type II abscesses failed first-line PD in 27 per cent (13/48) with 11 patients requiring surgical rescue, whereas first-line surgery failed in only 13 per cent (2/15). No deaths occurred after any surgical intervention, and there was no statistical difference in major complications between first-line surgical intervention and PD for type II or III abscesses. These results support the algorithmic approach and demonstrate that minimally invasive surgical intervention is a safe and effective modality for large PHA. We recommend that select patients with large, complex abscesses should be considered for a first-line minimally invasive surgical approach depending on surgical experience and available resources.

Sessile serrated adenoma/polyp leading to acute appendicitis with multiple pyogenic liver abscesses: A case report

•

Appendicitis with liver abscess and sessile serrated adenoma/polyp is rare.

•

Ileocecal resection was performed for an inflammatory mass in the ileocecum.

•

The patient was successfully treated with a combination of surgery and antibiotics.

Introduction

Although appendicitis is a common disease, appendicitis concurrent with liver abscesses and sessile serrated adenoma/polyp (SSA/P) is rare.

Presentation of case

A 69-year-old man presented with symptoms of abdominal pain and fever. Computed tomography (CT) revealed multiple liver abscesses and an enlarged appendix with a pseudotumoral appearance, which suggested acute appendicitis. In the emergency operation, ileocecal resection was performed for the perforated appendicitis with an inflammatory mass in the ileocecum. On macroscopic examination, the torose lesion was localized at next to the appendiceal orifice. The tumor was diagnosed as SSA/P based on the microscopic finding. The postoperative course was uneventful, and the liver abscesses were cured by antibiotic therapy. The patient was discharged 17 days after the surgery.

Discussion

In this case, SSA/P localization at next to the appendiceal orifice was suggested as the cause of the perforated appendicitis with multiple liver abscesses. The patient was successfully treated with a combination of surgery and antibiotic therapy.

Conclusion

This is the first reported case of a patient with SSA/P that led to acute appendicitis with multiple pyogenic liver abscesses.

A case of sudden onset septicemia in recurred gastric cancer following s1 plus docetaxel treatment

Pyogenic liver abscess in patients with malignant disease is a fatal state and is easily diagnosed. We presented a rare case of sudden fatal septicemia following anticancer treatment for recurred gastric cancer due to multiple liver abscesses which could not be diagnosed. A 72-year-old male with recurred gastric cancer received anticancer agents. He had a history of distal gastrectomy with right hepatic lobectomy for hepatic metastasis. He received anticancer treatment in the outpatient's service center periodically, and his performance status was preserved with nothing in particular. After administrating docetaxel, he suddenly developed septicemia and multiple organ failure and died 5 days after strong medical supports. Pathological autopsy revealed that multiple minute abscesses of the liver which could not be detected macroscopically were the causes of fatal septicemia. The etiology, therapies and prognosis of rare entity are being discussed.

Optimal Treatment of Hepatic Abscess

Many treatment strategies have been proposed for pyogenic liver abscesses; however, the indications for liver resection for treatment have not been studied in a systematic manner. The purpose of our study was to evaluate the role of surgical treatment in pyogenic abscesses and to determine an optimal treatment algorithm. We retrospectively reviewed the medical records of all patients who had a pyogenic liver abscess at Rhode Island Hospital between 1995 and 2002. Abscesses and treatment strategies were classified into three groups each. The abscess groups included Abscess Type I (small <3 cm), Abscess Type II (large >3 cm, unilocular), and Abscess Type III (large >3 cm, complex multilocular). The treatment strategy groups included Treatment Group A (antibiotics alone), Treatment Group B (percutaneous drainage plus antibiotics), and Treatment Group C (primary surgical therapy). Descriptive statistics were calculated and χ2 used for comparison with a P < 0.05 considered significant. Our study consisted of 107 patients with pyogenic liver abscess. The success rate for small abscesses treated with antibiotics was 100 per cent. The success rate with antibiotics and percutaneous drainage for large, unilocular abscesses was 83 per cent and for large, multiloculated abscesses was 33 per cent. None of the 27 patients who had surgical therapy for large, multiloculated abscesses had recurrences. Surgical treatment for large (>3 cm), multiloculated abscesses had a significantly higher success rate than percutaneous drainage plus antibiotic therapy (33% versus 100%, P ≤ 0.01). The mortality rate for the percutaneous drainage plus antibiotic group was not significantly different from the primary surgical group (4.2% versus 7.4%, P = 0.40). We propose a treatment algorithm with small abscesses being treated with antibiotics alone; large, uniloculated abscess with percutaneous drainage plus antibiotics; and large, multiloculated abscessed treated with surgical therapy.
