Computed tomography of intraperitoneal abscesses.

Eighty-seven patients with the clinical suspicion of an intraperitoneal abscess were examined by computed tomography. In 83 of these patients CT gave true positive or true negative results in reference to the diagnosis of local intraperitoneal fluids. The final diagnosis confirmed 28 abscesses in 26 patients. Most of these abscesses were in the left subphrenic space, the right subphrenic space, the right anterior subhepatic space, and the pelvis. The morphological criteria for intraperitoneal abscesses, shown by CT, are defined. Direct signs include form, impression on nonintestinal organs, density value, gas collection, pyogenic membrane, and infiltration in surrounding tissue. Indirect signs include ascites and pleural effusion and/or pulmonary infiltration. Differential diagnostic problems of intraperitoneal abscesses are discussed.

The clinical characteristics and outcome of intraabdominal abscess in Crohn's disease.

BACKGROUND: We aimed to elucidate the incidence and natural course of abdominal abscess complicating Crohn's disease (CD). METHODS: Of 352 patients with CD who were observed at our hospital between 1985 and October 2001, we studied 35 patients (9.9%) with abscesses in the mid-abdominal region (the abdominal wall, peritoneal cavity, retroperitoneum, and subphrenic region). RESULTS: The cumulative incidence of complication with an abscess was 9% and 25%, respectively, 10 and 20 years after CD onset. Of the 35 CD patients with abscess, 60% had had surgery by the time of the present study. The age when the abscess developed was 30.1 +/- 8.1 years, and the duration of illness from the onset of CD until development of an abscess was 10.8 +/- 6.3 years (range, 0-29 years). The location of involvement was: abdominal wall, n = 14 (40%); peritoneal cavity, n = 10 (29%); retroperitoneum or iliopsoas, n = 9 (26%); and subphrenic region, n = 2 (6%). In terms of location of abscess, it occurred most often on the right side (65.7%). Almost all abscesses occurred near the site of an anastomosis. Diseased segments of the bowel responsible for abscess formation were categorized radiographically as showing mild stenosis (6.5%), intermediate stenosis and/or simple fistula (41.9%), and severe stenosis and/or multiple fistulas (51.6%). Conservative treatment (including drainage of abscess) alone was effective in 7 patients (20%) and surgery was needed in 28 patients (80%). During the 5.3-year follow-up after treatment for the abdominal abscess, 9 of the 35 patients (26%) had recurrence of an abscess, mostly within 3 years. CONCLUSIONS: Abscess formation was noted in about 10% of patients with CD, with 46% of abscesses occurring in a diseased bowel segment near an anastomotic site. Of the diseased bowel segments responsible for abscess formation, half had neither severe stenosis nor multiple fistulas. Almost all patients underwent surgery for the abscess, and, in more than a quarter of the patients, there was recurrence within a few years after surgery.

Giant horseshoe intra-abdominal abscess.

A study of 12 patients with giant horseshoe abscess of the abdominal and pelvic cavities seen at the Surgical Services of the University of Cincinnati Medical Center has emphasized the complexity and bizarre nature of these lesions. These infections represented a huge abscess or series of communicating abscesses extending from one subphrenic space along the corresponding paracolic gutter into the pelvis, up and along the opposite paracolic space, and into the other subphrenic space. Since these lesions occurred infrequently, they were often not recognized until they had become far advanced and had produced profound effects on the patients. The diagnosis was difficult and obscured by various factors including the postoperative state after laparotomy for complex diseases or serious injuries of the biliary tract, the genitourinary tract, or the alimentary tract. An important etiologic component of the formation of these giant abscesses was the continuing escape and collection of large volumes of fluid resulting from lesions of the biliary tract, postoperative hemorrhage, or an unrecognized large perforated peptic ulcer. Nine patients were treated successfully and 3 died. The many diagnostic and therapeutic problems presented by the patients with this interesting and complex lesion have emphasized the importance of earlier and more accurate diagnosis, early and adequate surgical drainage, intelligently applied antibiotic therapy and appropriate supportive treatment. Failure to recognize and drain effectively each of the component sections of this lesion led to continuing sepsis with prolonged morbidity, progressive debility, and death.

Efficacy of combined liver-lung scintillation imaging.

Of 116 patients who had undergone combined liver-lung scintillation imaging, 23 with negative studies had abnormal subphrenic spaces at operation, and 5 with positive studies had abnormal subphrenic spaces at laparotomy (hematomas, bile spillage, serous fluid or abscess); 4 of 6 nonexplored positive studdies showed resolution of defects on serial imaging. Other information obtained included abnormalities intrinsic to liver, lungs or spleen; evidence suggestive of left subphrenic pathology; and reliable information about the right subphrenic space even in the presence of intrathoracic pathology, including effusions.

Intra-abdominal abscesses in children.

Forty-one intra-abdominal abscesses in 30 Nigerian children seen over a 2-year period at the Obafemi Awolowo University Teaching Hospital were studied prospectively to determine their location, aetiology, microbiology and clinical course. Thirty-four abscesses (83%) were intraperitoneal with the subphrenic spaces and pelvis being the commonly involved intraperitoneal sites. Six abscesses (15%) were retroperitoneal while there was only one visceral abscess (2%). Diseases of the gastrointestinal tract occurring in 20 patients (67%) were responsible for the majority of intraperitoneal abscesses, while suppurating external iliac adenitis was the major cause of retroperitoneal abscesses. There were 62 microbiological isolates, with 52% being anaerobic bacteria and 47% aerobic bacteria. A fungus, Candida, was isolated once (2%). Escherichia coli and Staphylococcus aureus were the commonest aerobic bacteria, while Bacteroides and anaerobic streptococci were the commonest anaerobes. Sixteen patients (53%) had a mixed flora of aerobic and anaerobic bacteria, while in seven patients each (23%) only aerobic or anaerobic bacteria were isolated. The mortality rate in this series was 23%. Association of an intra-abdominal abscess with remote organ failure, postoperative anastomotic leakage, non-localization of the abscess within the peritoneal cavity and gastrointestinal perforation due to typhoid enteritis was found to portend poor prognosis.

Bare area abscess: imaging findings and potential communication with the mediastinum.

The bare area of the liver is not usually visualized by standard cross-sectional imaging techniques except in patients with ascites or subphrenic collections where this area is spared of fluid. We present a case of an abscess in the bare area of the liver with imaging findings and demonstration of a communication with the mediastinum, not previously described.

Computed tomography of fluid collections within the abdomen.

Computed tomography is ideally suited for detecting mass lesions and for distinguishing "solid" from "cystic" masses. In the majority of cases, the recognition of fluid collections is unequivocal and lead to direct management decisions. Subphrenic, intrahepatic, and subhepatic abscesses can be recognized, aspirated, and drained. Using CT control, pancreatic pseudocysts can be managed similarly. Renal cysts can be accurately diagnosed with CT, especially with contrast enhancement, and then even the occasional case in which hydronephrosis may be a problem can be distinguished. Very occasionally, solid tumors containing mucinous material or lipoid can appear as cystic lesions, especially in the suprarenal, ovary, liver, or lymph nodes, and, conversely, abscesses may have higher tissue attenuation values, suggesting a solid lesion. It is most important to ensure that bowel is adequately labeled with contrast so that is is not misdiagnosed as a mass lesion.

Percutaneous imaging-guided abdominal and pelvic abscess drainage in children.

Percutaneous imaging-guided drainage is the first-line treatment for infected or symptomatic fluid collections in the abdomen and pelvis, in the absence of indications for immediate surgery. The technology and expertise needed to perform percutaneous abscess drainage are widely available and readily adapted for use in the pediatric population. Catheter insertion procedures include the trocar and Seldinger techniques. Imaging guidance for drainage is most commonly performed with ultrasonography (US), computed tomography, or US and fluoroscopy combined. Abscesses in locations that are difficult to access, such as those deep in the pelvis, subphrenic regions, or epigastric region, can be drained by using the appropriate approach-transrectal, transgluteal, intercostal, or transhepatic. Although the causes of abscesses in children differ slightly from those of abscesses in the adult population, the frequency of successful treatment with percutaneous abscess drainage in children is 85%-90%, similar to that in adults. With expertise in imaging-guided drainage techniques and the ability to adjust to the special needs of children, interventional radiologists can successfully drain most abscesses and obviate surgery. Successful adaptation of abscess drainage techniques for pediatric use requires attention to the specific needs of children with respect to sedation, dedicated resuscitation and monitoring equipment, avoidance of body heat loss, minimization of radiation doses, and greater involvement of family compared with that in adult practice.

Histopathology of mixed anaerobic intraabdominal infection in mice.

This study characterized acute peritonitis and chronic abscess formation resulting from experimental mixed anaerobic infection with Bacteroides melaninogenicus and Fusobacterium necrophorum. At intervals after infection liver and spleen samples were obtained, fixed, and processed for histological examination. An acute to chronic infection progressed in mice infected with this mixture of anaerobic bacteria, whereas, no infection resulted when either organism was injected alone. Acute inflammatory cell infiltrates were noted in tissue samples at 12 h postinfection. Small, discrete areas of liver cell necrosis with neutrophilic infiltrates were observed as early as 24 h. By 48 h after infection the liver parenchyma was infiltrated with both acute and chronic inflammatory cells, with moderate to severe hepatocyte degeneration recognized at 72 h. Large intrahepatic abscesses were present in the subphrenic (upper lobe) area 2 to 6 weeks after experimental infection.

CT of splenic and perisplenic abnormalities in septic patients.

Splenic and perisplenic pathology, demonstrated by CT examination in 14 septic patients, was correlated with the clinical course and with surgical and pathologic findings available. Twelve patients were intravenous drug addicts and two patients developed bacteremia associated with bacterial endocarditis. The CT findings were divided into three groups: (1) Single wedge-shaped peripherally located defects were seen in five patients; there was good response to medical therapy without other complications. (2) Larger and/or multiple, rounded or oval lesions were present in five patients; two of these patients had splenic abscesses proven on subsequent splenectomy. (3) Multiple splenic lesions and fissures associated with perisplenic and subphrenic fluid collections were seen in four patients; infected splenic infarcts, splenic fractures, and infected perisplenic hemorrhagic fluid collections were found in this group of patients. The CT examination in septic patients can reliably demonstrate splenic and perisplenic pathology, and its appearance contributes greatly to the overall clinical assessment and surgical approach.

Endoscopic drainage of esophageal suture line leaks.

Suture line leaks after esophageal or gastric surgery are associated with high morbidity and mortality rates. We report a new approach to the management of this problem, which has been used successfully in the treatment of nine patients with such leaks who were treated at or referred to our unit. The suture line defect is first visualized by endoscopy, after which a sump nasogastric tube is advanced down the esophagus and out through the defect into the abscess cavity. The tubes are irrigated intermittently to achieve patency and maintained with continuous suction. Separate pleural or subphrenic collections are drained by conventional techniques. After the injection of contrast down the tube, serial radiologic studies are used to monitor progress and to guide the slow withdrawal of the tube as the cavity collapses.

Determinants of death in patients with intraabdominal abscess.

To better define determinants of death in patients with intraabdominal abscess, 143 patients from a 5-year hospital experience were reviewed. Abscesses were most commonly results of trauma, spontaneous gastrointestinal perforations, and technical errors. Clinical presentation of abscess was quite variable as were criteria to justify reoperation for drainage. Abscesses occurred most commonly in the subphrenic space, pelvis, or subhepatic space. Complete abdominal exploration was employed most frequently for drainage. Those factors that were associated with a fatal outcome were: organ failure (P < 0.001), lesser sac abscess (P < 0.001), positive blood culture (P < 0.01), recurrent and/or persistent abscess (P < 0.01), multiple abscesses (P pE 0.01), age > 50 years (P < 0.03), and subhepatic abscess (P < 0.03). These data suggest that deaths from abdominal abscess are consequences of ineffective surgical drainage and failure of host defense mechanisms.

Chronic melioidosis: a report of the first case in Japan.

A 41-year-old Japanese male with uncontrolled diabetes mellitus and alcoholic liver dysfunction developed melioidosis after his business trip to Indonesia and Singapore in 1988. His disease started with spiked fever on the following day after extraction of a tooth, and a liver abscess developed, followed by abscesses in the spleen and in the subphrenic space. In spite of splenectomy and intensive antimicrobial treatments for three months, he developed parotitis, prostatitis, and abscess of the right submandibular gland at 5 to 16-month interval. Pseudomonas pseudomallei was isolated from the blood and pus from each abscess. The lung was not involved. At present, he has returned to work, with continued intravenous instillation of imipenem/cilastatin.

Percutaneous catheter versus open surgical drainage in the treatment of abdominal abscesses.

In the past 3 years, percutaneous catheter drainage (PCD) was performed for 24 abdominal and retroperitoneal abscesses while open surgical drainage (OSD) was used for treatment of 24 similar abscesses at the affiliated hospitals of UMDNJ-Rutgers Medical School. Although the method of treatment was arbitrarily selected by the attending physician, the two groups were similar with respect to abscess location, underlying illnesses, and previous operations. In the PCD group, 17 of 24 abscesses developed after operations versus 16 of 24 in the OSD group. Location of abscesses were: PCD group: abdominal (9), renal (5), pelvic (4), subphrenic (3), hepatic (2), pancreatic (1); OSD group: abdominal (10), renal (4), subphrenic (4), pelvic (3), hepatic (2), pancreatic (1). With PCD, the abscesses were localized by ultrasound or computerized tomography scan; a 20- or 22-gauge needle passed into the cavity, followed by progressively larger guide wires, dilators, and catheters; the pus evacuated; and abscess cavity thoroughly irrigated with sterile saline. Percutaneous catheter drainage was successful in 22 of 24 cases. There were two inconsequential complications. The mean post-PCD hospital stay was 11.7 days. With OSD, five patients developed major complications, including three deaths from sepsis. The mean post-OSD stay for surviving patients was 21.2 days. The advantages of PCD versus OSD are: 1) precise noninvasive localization of abscesses, 2) avoidance of general anesthesia, 3) avoidance of major complications, and 4) shorter postdrainage hospital stay. Open surgical drainage should be reserved for cases where PCD fails to control sepsis, close fistulae, or when noninvasive scanning either fails to demonstrate a discrete abscess in the face of intra-abdominal sepsis or identifies an abscess that cannot be percutaneously drained without traversing the bowel.

[The surgical procedure and treatment of paravesical abscesses in acute cholecystitis in middle-aged and elderly patients].

The results of 238 operations performed for acute cholecystitis within 1985-1990 have been analysed. Of them in 11 (4.6%), paravesical (8 cases) and intrahepatic (3) abscesses were revealed. In 8 patients, the presence of an abscess at the preoperative period was supposed. All the patients were admitted to the hospital later than 24 h from the onset of the disease and operated on within 1 to 5 days. Perforation of the gallbladder was revealed in 5 patients, gangrene with destruction of its wall--in 3. Abscess location near the gallbladder fundus was noted in 4 patients, near its neck--in 2, along the medial surface--in 2. A unicameral abscess was revealed in 5 cases, a multicameral one--in 3. The operative treatment presents technical difficulties and consists in performance of cholecystectomy (sometimes--Pribram's mucoclasis), external drainage of the common bile duct and abscess cavity, drainage of the subhepatic and subphrenic space. One 82-year old patient died.

Abscess formation following spilled gallstones during laparoscopic cholecystectomy.

OBJECTIVE: Our purpose was to report the occurrence of abscess following spilled gallstones during laparoscopic cholecystectomy as experienced at Good Samaritan Hospital, and to compare it to the experience of other institutions in order to identify the incidence, characteristics and possible risk factors for the development of this complication. METHODS: Four case reports of abscess following spilled gallstones during laparoscopic cholecystectomy are presented. The English literature was reviewed, and characteristics of the case reports found in the literature were compared. RESULTS: In four years at this institution, four reports of abscess formation following laparoscopic cholecystectomy have been identified. Two occurred in elderly females and were located in the right flank in both. Two were in middle-aged men, both diabetic. One abscess was in the right flank and one in the right pleural space. Twenty-three cases were found in the literature. The average age was 65 years; there were 12 men and 11 women. The locations of abscess formation were trocar sites (most common), right subphrenic space, right flank or retroperitoneum, and pelvis. The average time to presentation was 4-5 months (range 4 days-12 months). CONCLUSIONS: Abscess formation following spilled gallstones during laparoscopic cholecystectomy occurs infrequently, but can be debilitating and require more than one procedure. The older population appears to be at greater risk. Future prospective studies of patients who undergo laparoscopic cholecystectomy are needed to more accurately determine the incidence of this complication and to identify the population at risk.

Relaparotomy for postoperative intra-abdominal sepsis in jaundiced patients.

During the period 1979-84, 30 abdominal re-explorations were performed for postoperative intra-abdominal sepsis and single or multiple organ failure in jaundiced patients. Postoperative sepsis was caused by intra-abdominal abscess in 16 cases (53 per cent), by suture line leakage in 9 cases (30 per cent) and by technical error in 5 cases (17 per cent). Abscesses occurred most commonly in the subphrenic space (6 cases), in the subhepatic space (6 cases) and in the lesser sac (5 cases). Sepsis was associated with single organ failure in 20 cases and with multiple organ failure in 10 cases. The overall mortality rate was 50 per cent (15/30). Factors that were statistically associated with fatal outcome were: serum bilirubin greater than 100 mumol/l (P less than 0.008), positive blood culture (P less than 0.013), malignant disease (P less than 0.02), multiple organ failure (P less than 0.02) and age greater than 60 years (P less than 0.031). Mortality rose with the number of failed organs. Autopsy revealed continuing sepsis in 12 of the 15 fatal cases. Because mortality was high in spite of adequate operative drainage at relaparotomy, it is concluded that earlier definitive diagnostics are needed to lower the mortality rate.

Complications of laparoscopic cholecystectomy: an analysis of 200 cases.

Complications of the initial 200 cases of laparoscopic cholecystectomy (LC) at the Cathay General Hospital within a period of 11 months were reviewed from video documents of the operations and clinical records. The major complication rate was 3.5%, including one common bile duct (CBD) injury (0.5%), three retained CBD stones (1.5%), one subphrenic fluid accumulation (0.5%), one liver abscess (0.5%) and one cystic duct stump bile leakage (0.5%). All major complications were cholecystectomy-related, and only one of the seven occurred in cases of acute cholecystitis. Age and sex were not related to its occurrence. The rate of minor complications ranged from 0.5% to 10%; they were: shoulder and back pain (10%), gall bladder perforation (10%), retained stones in the abdominal cavity (5%), transient nausea and diarrhea (5%), extension of umbilical port to a mini-laparotomy (3.5%), prolonged operation time > three hours (2%), subcutaneous emphysema (1.5%), wound infection (1.5%) and prolonged ileus (0.5%). The minor complications occurred largely in patients with acute cholecystitis. The complications occurred mostly during the early period of our study, indicating a learning period phenomenon. These could have been avoided if we had had a thorough knowledge of the potential complications and had strictly followed the principles of laparoscopic surgery. We conclude that LC is safe and the complication rate is not higher than that for open cholecystectomy. Most of the complications are preventable if LC is performed by qualified biliary surgeons following strict precautions.
