Percutaneous drainage of intra-abdominal abscesses guided by real-time ultrasonography

From October 1982 to October 1984, a percutaneous drainage under realtime ultrasound guidance was performed in 53 patients with abdominal abscesses. The location of the abscesses was subphrenic (23), retroperitoneal (16), and intrahepatic (14). A safe access route was found by using ultrasound and fluoroscopy in 53 out of 55 patients (96 p. 100). Percutaneous drainage failed in 8 patients and 3 of these patients died. The causes of death were: cerebral abscess (1), renal failure after surgery for correction of a duodenal fistula (1), and pancreatic abscess (1). The other five patients were cured by surgical drainage. Two complications were observed: one case each of pneumothorax and purulent peritonitis. Forty-five patients were healed by percutaneous drainage without operation. The duration of the catheter drainage was 14 days +/- 13 (m +/- 1 SD). Our results suggest that percutaneous drainage under realtime ultrasound guidance is an efficient and safe way to treat abdominal abscesses.     

Percutaneous postoperative intra-abdominal abscess drainage after elective colorectal surgery

Intra-abdominal abscesses are a frequent source of morbidity and mortality following both elective and emergent surgery of the alimentary tract. CT-guided percutaneous drainage of intra-abdominal abscess is an alternative to immediate surgical intervention. We studied the clinical characteristics and outcomes of patients undergoing percutaneous drainage of intra-abdominal abscesses arising after elective colorectal procedures. We retrospectively identified 40 patients with postoperative intraabdominal abscess following elective colorectal surgery who underwent CT-guided percutaneous drainage with a Von Sonnenberg sump drain between 1990 and 1998. The most common presenting symptoms were pyrexia in 39 (97%), abdominal tenderness in 32 (80%), guarding in 1 (2.5%) and abdominal mass in 3 (7.5%); no patient had generalized peritonitis. The most common index procedure was proctocolectomy with ileoanal anastomosis and ileal Jpouch in 12 (30%) patients. Drainage was performed using an anterior approach in 32 (80%) and a transgluteal window in 8 (20%) patients. Thirty-five (87.5%) patients had a single collection, while 2 (5.0%) patients had 2 collections and 3 (7.5%) patients had 3 collections. Thirteen (32.5%) patients had perioperative steroids, 30 (75%) had preoperative antibiotics, and 40 (100%) had postoperative antibiotics. Follow-up at a mean of 35.8 days revealed complete resolution of abscess in 26 (65%) patients; 14 (35%) patients had residual or recurrent abscess successfully treated by repeat drainage in 8 patients and requiring laparotomy in 6. Percutaneous CT-guided abscess drainage is an effective method for treating intra-abdominal abscess following elective colorectal surgery. The primary success was 65% after the first and 85% after a second drainage. In conclusion, this technique should be considered as the treatment of choice in patients with localized intra-abdominal abscess without signs of generalized peritonitis.

Computerized tomographic scan-guided drainage of intra-abdominal abscesses

PURPOSE: Computerized tomographic (CT) scan-guided percutaneous drainage of intra-abdominal abscesses has changed the colon and rectal surgeon's approach to preoperative and postoperative intra-abdominal infections. This study is an effort to prove the efficacy of CT scan-guided percutaneous drainage. METHODS: A retrospective study was performed on 133 patients who underwent CT scan drainage of intra-abdominal abscesses over a 6.3-year period. RESULTS: 67 patients had underlying lower gastrointestinal disease. Twenty-three of these patients (34 percent) had spontaneous abscesses and underwent drainage as a preoperative or final modality, whereas 44 patients (66 percent) were drained postoperatively. In 78 percent of patients, surgery was successfully avoided or delayed. Ten patients had acute diverticulitis associated with a large pelvic abscess. Eight patients underwent successful CT scanguided percutaneous drainage, yielding an 80 percent success rate. Morbidity from the CT scan-guided percutaneous drainage procedure in spontaneous and postoperative groups was 0 percent and 9 percent, respectively. Mortality was 9 percent and 11 percent, respectively, and associated with an elevated Acute Physiology and Chronic Health Evaluation II (APACHE II) score. CONCLUSION: CT scan-guided percutaneous drainage of intra-abdominal abscesses is an important adjunct to colon and rectal surgery because roughly 80 percent of spontaneous and postoperative abscesses were successfully managed.Poster presentation at the meeting of The American Society of Colon and Rectal Surgeons, Chicago, Illinois, May 2 to 7, 1993.     

Endoscopic transpapillary abscess drainage for a patient with giant pyogenic liver abscess

The primary modalities for management of liver abscesses are usually antibiotics and percutaneous drainage. However, in patients with ascites or bleeding tendency, the percutaneous puncture of liver abscesses may be unsuitable. We applied a new approach, nasobiliary tube drainage, for a giant pyogenic liver abscess following diagnostic endoscopic retrograde cholangiopancreatography. Pyogenic liver abscess is often biliary in origin, and this new approach includes assessment of biliary abnormality for the management of the abscess, enabling treatment of parients in whom puncture of the abscess is considered dangerous because of massive ascites around the liver. We propose that this procedure is useful in the management of a subgroup of patients with pyogenic liver abscess. To our knowledge, no previous reports of endoscopic transpapillary abscess drainage in pyogenic liver abscess are available.     

Percutaneous versus open operative drainage of intra-abdominal abscesses.

This article has tried to provide some perspective on the results of surgical and percutaneous drainage of intra-abdominal abscesses and the impact of CT localization on the successful management of this problem. It is most likely that the recent decrease in mortality for intra-abdominal abscesses over the past decade is due to a variety of factors, including better antibiotics, more aggressive critical care, and earlier diagnosis and treatment of the intraabdominal problem. These factors combined to reduce the incidence of pre-drainage organ failure and the degree of physiologic derangement of these patients at the time of their abscess drainage. Percutaneous drainage and surgical drainage techniques should not be considered competitive but rather complementary. If an abscess is accessible by percutaneous techniques, it is reasonable to consider a nonoperative approach to the problem. It is also clear that patients should respond promptly to whatever technique is employed to drain their intra-abdominal abscess. An improvement should be seen clinically within 24 to 48 hours following drainage. Should improvement not be forthcoming, the patient must be aggressively re-evaluated with repeat CT and decisions made by the responsible surgeon in consultation with the radiologist as to the next appropriate course of action. As our review of the Wayne State University experience suggested, patients are never too sick for an appropriate operation. Although it appears that most abscesses can be successfully treated by percutaneous drainage, pancreatic abscesses with pancreatic necrosis should generally be treated by surgical debridement, usually accompanied by repeated explorations. In addition, splenectomy has not yet been replaced by percutaneous drainage of splenic abscesses.     

Percutaneous drainage of abscesses in patients with Crohn's disease

The hospital courses of 9 patients with intraabdominal abscesses and Crohn's disease who underwent abscess drainage utilizing percutaneous techniques were reviewed. Percutaneous methods brought about resolution of fever, leukocytosis, and the abscess cavity in 8 patients. In 5 of these, definitive cure was achieved with percutaneous drainage. In 3, single-stage bowel surgery and fistulectomy were performed following resolution of the abscess cavities and improvement of clinical signs and symptoms. All patients had uncomplicated postoperative courses. Percutaneous drainage should be the initial drainage procedure in treating postoperative abscesses, and, when performed preoperatively, can diminish surgical morbidity.     

Management of abdominal and pelvic abscess in Crohn's disease

Patients with Crohn’s disease may develop an abdominal or pelvic abscess during the course of their illness.This process results from transmural in ammation and penetration of the bowel wall,which in turn leads to a contained perforation and subsequent abscess formation.Management of patients with Crohn’s related intra-abdominal and pelvic abscesses is challenging and requires the expertise of multiple specialties working in concert.Treatment usually consists of percutaneous abscess drainage(PAD)under guidance of computed tomography in addition to antibiotics.PAD allows for drainage of infection and avoidance of a two-stage surgical procedure in most cases.It is unclear if PAD can be considered a definitive treatment without the need for future surgery.The use of immune suppressive agents such as anti-tumor necrosis factor-α in this setting may be hazardous and their appropriate use is controversial.This article discusses the management of spontaneous abdominal and pelvic abscesses in Crohn’s disease.     

Transoralgastric gastroscopic debridement for peripancreatic abscess: a special case report

Transoralgastric debridement for pancreatic abscess is one of the successful applications of NOTES in clinical practice. We present a case report as follows: a 71-year-old female was hospitalized due to acute biliary pancreatitis. Three weeks after onset, the secondary abdominal CT showed a peripancreatic abscess. A passageway between the gastric wall and the abscess was made with a high-frequency puncher under the guidance of an ultrasonic gastroscope and then a gastroscope was directly inserted into the abscess, and a large amount of solid necrotic tissue was taken out with foreign body forceps and snare under the direct vision of a gastroscope. Then a 8.5F double-J stent and a nasobiliary drainage tube were inserted. After three times of intra-abdominal abscess debridement and repeated rinsing with an antibiotic solution, abdominal CT revealed the intra-abdominal abscess nearly disappeared and the patient discharged from hospital.     

Factors Affecting the Successful Management of Intra-Abdominal Abscesses With Antibiotics and the Need for Percutaneous Drainage

Purpose There is no definite consensus on the management of intra-abdominal abscesses in adults. This retrospective study evaluated the use of antibiotic therapy and percutaneous image-guided drainage in adult patients with intra-abdominal abscesses. Methods A retrospective chart review of 114 patients with intra-abdominal abscesses was conducted. Data collected included patient demographics, presenting symptoms, radiographic interpretation, vital signs, antibiotic coverage, laboratory values, and details of the hospital course. Bivariate statistical tests were performed using the Wilcoxon rank-sum test, chi-squared test, or Fisher's exact test, where appropriate. Results Sixty-seven of 114 patients (59 percent) had intra-abdominal abscesses resulting from appendicitis, diverticulitis in 30 patients (26 percent), postoperative in 13 patients (11 percent), and undetermined in 4 patients (4 percent). Three patients (3 percent; 95 percent confidence interval, 1–8 percent) failed conservative management and underwent urgent operation. Sixty-one (54 percent; 95 percent confidence interval, 44–63 percent) patients improved with intravenous antibiotic therapy alone. Fifty patients (44 percent; 95 percent confidence interval, 35–54 percent) underwent image-guided percutaneous drainage after 48 to 72 hours of antibiotic therapy. Patients who improved on antibiotics alone had average abscess diameter of 4 cm, whereas patients who underwent percutaneous drainage had average diameter of 6.5 cm (P < 0.0001). Maximal temperature at time of admission was 100.8°F for antibiotic group and 101.2°F for percutaneous drainage group (P = 0.0067). Conclusions The majority of the patients with intra-abdominal abscesses improved with antibiotic therapy alone. Those patients with an abscess diameter >6.5 cm and temperature at admission >101.2°F have higher likelihood of failing conservative therapy with antibiotics alone and requiring percutaneous drainage.

Percutaneous abscess drainage

We have drained 50 abscesses in 40 patients. The success rate was 100% for entering the abscess cavities and 98% for establishing catheter drainage. The success rate for treating the abscess (i.e., no surgery required) was 88%. We drained all abscesses for which a safe access route was available, regardless of the abscess's characteristics. Abscesses which are not unilocular may be successfully treated by percutaneous drainage. In critically ill patients and those unsuitable for surgery, catheter drainage is useful until the patient becomes stable. When surgery is not feasible, percutaneous procedures may be the patient's only hope for survival.     

Liver Abscess as a Complication of Regional Enteritis: Interventional Considerations

Although intra-abdominal abscesses are relatively frequent in the setting of regional enteritis, liver abscesses are rare. Pylephlebitis, steroid administration, and biliary fistulization have been suggested as inciting factors. This report describes the first attempted percutaneous drainage of a liver abscess which was a complication of regional enteritis. The percutaneous drainage proved inadequate therapy due to significant disease outside the liver involving the bowel. A review of all cases reported to date in the literature suggests that although percutaneous drainage might prove to be a satisfactory temporizing measure, all patients will require surgical exploration for definitive therapy.     

Percutaneous drainage of lung abscess

Most lung abscesses are successfully treated with antibiotics. However, occasional patients with lung abscesses that drain poorly, causing persistent fever and toxic symptoms, may require surgical intervention. Lobectomy is the most frequent surgical procedure. Some patients are debilitated and have underlying medical conditions such as heart disease, chronic pulmonary disease, or liver disease that may render surgical intervention risky. Recently there have been reports of percutaneous drainage of lung abscess with good results. We have successfully carried out percutaneous drainage of lung abscess in 4 patients and an infected bulla in 1. All patients had failed to respond to therapy with antibiotics and postural drainage. There was prompt disappearance of the fluid level in the cavity, decline in temperature, and abatement of toxic symptoms with drainage. The cavities closed gradually over the next 6-12 weeks. The patients tolerated the chest tube well and there were no side effects from the tube drainage. Percutaneous tube drainage is the surgical treatment of choice in the medically complicated patient with a poorly draining lung abscess.     

Treatment of Intra-Abdominal Abscesses in Crohn’s Disease: A Nationwide Analysis of Patterns and Outcomes of Care

Background

Abdominal abscesses are a common complication in Crohn’s disease (CD). Percutaneous drainage of such abscesses has become increasingly popular and may deliver outcomes comparable to surgical treatment; however, such comparative data are limited from single-center studies. There have been no nationally representative studies comparing different treatment modalities for abdominal abscesses.

Methods

We identified all adult CD-related non-elective hospitalizations from the Nationwide Inpatient Sample 2007 that were complicated by an intra-abdominal abscess. Treatment modality was categorized into 3 strata—medical treatment alone, percutaneous drainage, and surgery. We analyzed the nationwide patterns in the treatment and outcomes of each treatment modality and examined for patient demographic, disease, or hospital-related disparities in treatment and outcome.

Results

There were an estimated 3,296 hospitalizations for abdominal abscesses in patients with CD. Approximately 39 % were treated by medical treatment alone, 29 % with percutaneous drainage, and 32 % with surgery with a significant increase in the use of percutaneous drainage since 1998 (7 %). Comorbidity burden, admission to a teaching hospital, and complicated Crohn’s disease (fistulae, stricture) were associated with non-medical treatment. Use of percutaneous drainage was more common in teaching hospitals. Mean time to percutaneous drainage and surgical treatment were 4.6 and 3.3 days, respectively, and early intervention was associated with significantly shorter hospitalization.

Conclusions

We describe the nationwide pattern in the treatment of abdominal abscesses and demonstrate an increase in the use of percutaneous drainage for the treatment of this subgroup. Early treatment intervention was predictive of shorter hospitalization.

Endoscopically drained abdominal abscess compressing the sigmoid

Intra-abdominal abscesses (IAA) complicate numerous medical and surgical pathologic conditions. Accurate radiological diagnosis combined with percutaneous or surgical drainage and antibiotics is the current standard of care for IAA. We herein report a case of a 52-year-old woman with a 10-day history of fever and abdominal pain. An intra-abdominal abscess externally compressing the sigmoid was revealed and successfully drained during colonoscopy.     

CT-guided Percutaneous Drainage of an Amebic Liver Abscess

Computed tomogriiphy (CT) has been successfully applied to the diagnosis of abnormalities of the solid abdominal organs. In a patient with liver abscess, CT was used to direct percutaneous drainage of a loeulated portion of the abscess. The use of CT for liiopsy and treatment of intra-abdominal diseases should become more common as sean time decreases.     

Splenic abscess: sonographic diagnosis and percutaneous drainage or aspiration.

During a recent 5-year period, 12 patients with splenic abscesses were evaluated by abdominal ultrasound (US) examination. Multifocal abscesses were noted in seven patients, three of them were secondary to infectious endocarditis, three were in immunosuppressed state, and one was caused by tuberculosis. The latter four patients had developed splenic microabscesses with a diameter of less than 1.5 cm. The larger abscesses showed an irregular wall, weak or no internal echoes, ovoid or round in shape, and accompanied by mild to moderate distal acoustic enhancement. Wedge-shaped abscesses were typically noted in patients with infectious endocarditis and septic embolism. US-guided percutaneous drainage was done in five patients (abscesses greater than 4 cm). Simple aspiration in conjunction with antibiotic administration was done for seven smaller abscesses (diameter less than 3.5 cm) in five patients. A second drainage, either for a dislodged catheter or a recurrent abscess, was performed in two cases. All patients had uneventful clinical course following this therapeutic approach.     

Endoscopic drainage of lung abscesses: technique and outcome

BACKGROUND: Lung abscesses commonly respond well to antibiotic therapy. In patients in whom conventional therapy fails, either percutaneous catheter drainage or surgical resection are usually considered, but are frequently problematic. This study describes our experience with endoscopic lung abscess drainage in patients in whom antibiotic therapy fails. METHODS: Patients in whom antibiotic therapy for lung abscess (enlarging cavity or lack of improvement of clinical status) was unsuccessful were considered candidates if an airway connection to the cavity was present. Treatment decisions were made in a multidisciplinary chest conference. Pigtail catheters were placed via a guidewire approach into the cavities. The abscesses were flushed twice daily with gentamycin solution. If fungal infection was suspected, once-daily amphotericin B was added to the regimen. RESULTS: Forty-two patients, from January 2000 to May 2002 (17 woman and 25 men) were included in this study (mean age, 48.9 years). Catheter placement was successful in 38 patients and led to successful therapy after a mean of 6.2 days of treatment (range, 3 to 21 days). Two patients required transient ventilation after catheter placement; there were no other complications. CONCLUSIONS: Endoscopic lung abscess drainage in selected patients in whom antibiotic therapy fails is feasible and successful in experienced hands. This treatment represents an additional option for the chest physician other than percutaneous catheter drainage or surgical resection.     

Abscesses in Crohn's disease: outcome of medical versus surgical treatment

GOALS: To compare the long-term outcome of medical, percutaneous, and surgical treatment of abdominal and pelvic abscesses complicating Crohn's disease. STUDY: All patients with Crohn's disease and an abdominal abscess treated at one institution during a 10-year period were retrospectively identified. We reviewed hospital and outpatient records and contacted patients for telephone interviews. Outcome measures included abscess recurrence, subsequent surgery for Crohn's disease, and medications used at the time of most recent follow-up. RESULTS: Fifty-one subjects were identified, with a mean follow-up of 3.75 years. Fewer patients developed recurrent abscesses after initial surgical drainage and bowel resection (12%) than patients treated with medical therapy only or percutaneous drainage (56%) (p = 0.016). One half of the patients treated nonoperatively ultimately required surgery, whereas only 12% of those treated with initial surgery required reoperation during the follow-up period (p = 0.010). Most failures of nonoperative therapy occurred within 3 months. Medication use was similar between the treatment groups at the time of most recent follow-up. CONCLUSIONS: In this series, surgical management of abscesses in Crohn's disease was more effective than medical treatment or percutaneous drainage for prevention of abscess recurrence. However, nonoperative therapy prevented subsequent surgery in half of the patients and may be a reasonable treatment option for some patients.     

Endoscopic ultrasound‐guided drainage of pelvic abscess without fluoroscopy guidance

Background and Aims: Few case series are reported on endoscopic ultrasound (EUS)‐guided drainage of pelvic abscesses under fluoroscopy guidance. We hypothesized that EUS‐guided drainage of pelvic abscesses without fluoroscopy is an effective alternative to surgery in patients whose abscesses are not amenable to percutaneous drainage techniques. The aim of this study is to evaluate the clinical efficacy of EUS‐guided trans‐rectal/transcolonic drainage of pelvic abscess without fluoroscopy. Methods: Fourteen consecutive patients with pelvic abscesses not amenable to percutaneous drainage underwent EUS‐guided drainage over a period of 22 months. Main outcome measures were the resolution of the pelvic abscess on repeat imaging and improved clinical symptoms. Results: Fourteen consecutive patients were enrolled. EUS‐guided aspiration was performed in three patients. In two patients, dilatation and aspiration was performed, while trans‐rectal stent was placed in nine patients. All patients became afebrile within 72 h. Stent was removed in all patients, after confirming the resolution of the abscess on repeat computed tomography after 7 days. One patient in whom only aspiration was done had recurrence of fever and abscess on the seventh day and was treated by surgical drainage. A follow‐up EUS done in 13 of the patients after 3 months revealed no recurrence, and all patients were asymptomatic at 6 months. The procedure was uneventful in all patients. Conclusion: Endoscopic ultrasound‐guided drainage without fluoroscopy is a safe and effective modality of treatment for pelvic abscesses not amenable to radiologically guided drainage, thus reducing the need for surgical intervention.
