One hundred patients with suspected acute abdominal inflammation were imaged at 0.5, 2-3, 4-6, and 24 hours after the administration of Tc-99m HMPAO labeled autologous leukocytes. Scan findings were retrospectively compared with final diagnosis, serum C-reactive protein (CRP), and antibiotic treatment. Clinical findings were confirmed with surgery, barium enema, or sigmoidoscopy in 61 patients, and diagnosis was based only on clinical findings in 13 patients. In 26 patients, symptoms subsided before a final diagnosis was made. Tc-99m leukocyte images were positive in 45 of the 61 patients with a confirmed diagnosis, including all patients with acute cholecystitis (N = 4) and inflammatory bowel disease (N = 8). They were also positive in nineteen out of 25 patients who had acute colonic diverticulitis and in 6 out of 7 who had intra-abdominal abscesses. Abnormal activity was found in patients with colonic carcinoma, small bowel infarction, and acute appendicitis. Abnormal activity was visualized in 0.5-hour images in all but one of the positive cases. With the exception of two postoperative cases, malignant lymphoma, and a liver abscess, a CRP level of greater than 75 mg/L was associated with positive image findings. Antibiotic treatment did not affect imaging findings. Imaging with Tc-99m labeled leukocytes appears to be valuable for detecting and localizing abdominal inflammation, and three-phase imaging during the first 4-6 hours is recommended. In some cases, 24-hour images may be useful for distinguishing small bowel from large bowel inflammation.

Fifteen cases of extrahepatic rupture of amebic liver abscess have been reviewed. Five patients had thoracic rupture and ten had intra-abdominal rupture. Celiotomies were performed in five patients, with a preoperative diagnosis of acute appendicitis with perforation in four patients and generalized peritonitis of unknown origin in one patient. All 15 patients were treated with amebicides, including three patients with documented free intraperitoneal perforation who were not treated surgically. Twelve patients recovered uneventfully. Two patients with thoracic rupture developed secondary bacterial complications and in one case of free intraperitoneal rupture, a mistaken diagnosis of ruptured pyogenic abscess was made. Amebicidal therapy was delayed for four days. The patient died of multisystem organ failure. Amebicidal therapy is effective in the treatment of both unruptured and extrahepatic rupture of amebic liver abscess. Surgery should be required only for secondary bacterial complications.

The right anterior extrarenal space is composed of the perirenal fascia, the right anterior perirenal space, the right anterior pararenal space, and the liver capsule. To clarify the probable causes of an increasing width of the right anterior extrarenal space, the width was measured using ultrasonography for a period of 8 months. The right anterior extrarenal space was measured 3 cm from the superior renal pole and the smallest width obtained in several different scan planes was used. In 1,114 ultrasound examinations, 35 patients were found to have an increased width of the right anterior extrarenal space. Among the 35 cases, the common probable causes for such a condition were found in 27 cases. Eight patients had hyperchogenicity in the right pararenal space, a condition considered to be due to an acute inflammation, including acute pancreatitis, acute cecal diverticulitis, acute appendicitis, ischemic bowel, acute cholangitis, liver abscess, and penetrated duodenal ulcer. Chronic inflammations of an adjacent organ, a previous history of laparotomy, a malignancy with peritoneal metastases, and treatment with corticosteroid were considered the causes behind the condition in the 19 patients with normal echogenicity. For the remaining 8 patients, causes were not found during the follow-up period. This study indicates that life-threatening diseases, such as acute or chronic inflammatory diseases and malignancy of the abdomen, could be the cause of an increase in the width of this space.

Amoebic liver abscess is the most common extra-intestinal manifestation of amebiasis with approximately 10% of the world's population infected by this parasite. Actually, incidence of this infection is also increasing in industrialized countries, as a consequence of the more frequent immigration or travelling. Only 3-10% of patients with intestinal amebiasis develop liver abscess. A clinical case of suprainfection of amoebic liver abscess consequent on acute appendicitis is presented.

18 patients with complicated forms of intestinal amebiasis were operated on acute appendicitis, liver abscess or total necrotic colitis. Appendectomy, abscess drainage and colon resection were performed respectively. There were no postoperative deaths. Features of amebic appendicitis and total necrotic amebic colitis are described using clinical cases demonstrations. Recommendations for the treatment of these forms of amebiasis are given.

Acute portal vein thrombosis is a rare but severe complication of intra-abdominal infection. It can be life-threatening, given the risk of developing liver abscess and subsequent liver failure. Various types of hereditary thrombophilia are known risk factors for acute portal vein thrombosis. In addition to surgical treatment and potent antibiotic therapy, systemic administration of anticoagulants and locoregional trans-catheter delivery of thrombolytic agents are known to be effective. We present a case report of acute portal vein thrombosis with pylephlebitis caused by acute appendicitis, successfully treated with catheter-directed thrombolysis through the operatively recanalized umbilical vein. The umbilical vein is a promising access route to the portal vein. Therefore, this procedure is an effective and preferred treatment option for portal septic thrombosis, particularly because it does not require puncture of the liver parenchyma or catheterization through an infected peritoneal cavity.

We reported a case of amoebic liver abscess (ALA) in a 6-year-old Malaysian boy who presented with fever, lethargy, diarrhoea and right hypochondriac pain. On admission he was diagnosed with perforated acute appendicitis and a laparotomy was done. After surgery he developed acute respiratory distress. Ultrasonography, chest X-Ray and CT scan revealed two ALAs in the posterior segment of right lobe of liver, pleural effusion and collapsed consolidation of lungs bilaterally. Percutaneous liver abscesses drainage was done and intravenous Metronidazole was started. PCR carried out on the pus from the abscess was positive for Entamoeba histolytica. Patient however succumbed to the infection one week after admission.

An elderly gentleman presented to our emergency with a 10-day history of right upper quadrant pain and nausea with associated tenderness on examination. His white cell counts were raised with predominant neutrophils with ultrasound evidence of a heterogeneous sub-hepatic collection, not associated with fever, diarrhoea or vomiting. He had a similar episode 3 weeks ago, which resolved with antibiotics. Initially thought to be a perforated acute appendicitis or a liver abscess a CT scan was done to further substantiate our finding. This to the contrary revealed a perforated sub hepatic appendix. Patient was treated conservatively with IV fluids and antibiotics and the sub hepatic collection was aspirated under ultrasound guidance. He responded well to treatment and made an uneventful recovery.

A 15-year old boy was referred for evaluation of fever, productive cough, and recurrent/persistent right lower lobe (RLL) pneumonia of 1-month duration. Chest computed tomography scan showed RLL consolidation, with minimal pleural effusion and a liver abscess with sharp borders, containing a solid calcification in the lower portion. History revealed acute appendicitis with laparoscopic appendectomy 6 months prior to presentation, during which a fecalith dropped to the peritoneal cavity. Following laparoscopically guided drainage of the abscess the patient improved. Herein we describe a rare case of non-resolving RLL pneumonia secondary to pyogenic liver abscess caused by dropped appendicolith.

Sub hepatic caecum and appendix is an uncommon condition. It occurs due to incomplete rotation of foetal foregut and mal descent of caecum. This condition may be mistaken for acute cholecystitis, liver abscess, duodenal perforation or right renal calculus. Diagnosis may be delayed when acute appendicitis develops complications - appendicular rupture, perforation or localized abscess. The condition may be missed on ultra sound and CT abdomen may be inconclusive. Thus, surgeon should have a high index of suspicion in such undiagnosed right upper abdominal pain. In such cases an early diagnostic laparoscopy is suggested to avoid further complications. The present case is being reported due to difficulty in diagnosis of the condition, need for timely surgical intervention to avoid life threatening complications.
