Hemangiomas represent the most common primary tumor of the liver. Clinically the significance of these lesions is highly variable. The management of hemangiomas is controversial and is intimately related to the size, symptoms, and associated comorbidities of the patients who harbor these benign tumors. Series suggest that the vast majority of hemangiomas are less than 4 cm, asymptomatic, and clinically incidental findings. Symptomatic hemangiomas are large and associated with a constellation of vague upper abdominal complaints including pain, mass, distention, early satiety, and weight loss. A number of small series of surgically treated symptomatic hemangiomas have demonstrated enucleation as a safe and effective intervention. We report a collection of case reports using embolization as a primary treatment of symptomatic hemangiomas. The first patient is a 73-year-old black man previously treated for prostate cancer by radical prostatectomy and radiation. He developed weight loss, abdominal fullness, and early satiety. His symptoms were attributed to a large left lateral segmental liver mass that was biopsy proven to be a hemangioma. The second patient is a 49-year-old black women who complained of weakness, fatigue, night sweats, and anemia. The only abnormality discovered was a large right posterior hemangioma. The third patient is a 49-year-old black women with unexplained right upper quadrant pain and anemia who was found to have a 19 x 11 x 7.5-cm left hepatic hemangioma by CT. All three patients underwent elective treatment of their hemangiomas with highly selective hepatic embolization. There were no significant complications related to the procedures. Symptoms resolved for all patients acutely after treatment. The use of embolization for hepatic hemangiomas provides safe and effective treatment of the patient's symptoms while avoiding operative intervention, extended hospitalization, or postoperative recuperation. This treatment modality should be considered for the symptomatic hemangioma under elective conditions.

In the first part of our review, we discussed the general evaluation and clinical presentation of the various hepatic infections occurring in patients with AIDS. In addition, we focused on specific hepatic parenchymal infections. In this article, we will discuss the major clinical syndromes arising from opportunistic infections affecting the gallbladder (acalculous cholecystitis), biliary tree (AIDS-cholangiopathy), and pancreas (pancreatitis). Acalculous cholecystitis can develop in patients with AIDS who have not experienced the severe precipitating physiologic stresses normally required in patients without AIDS. The most common presentation is with right upper quadrant (RUQ) pain and tenderness. The diagnosis is a clinical one since there is no standard test, other than surgery. Cholecystectomy is the treatment of choice. The most common AIDS-associated infective complication of the biliary tree is AIDS-cholangiopathy. This is best viewed as a form of secondary sclerosing cholangitis resulting from a variety of opportunistic infections within the biliary tree. Affected persons present with RUQ pain and have marked elevations in the canalicular enzymes, alkaline phosphatase, and gamma-glutamyl transferase. Morphologic abnormalities are identified by endoscopic retrograde cholangiopancreatography. These include stricturing, dilatation, and beading of the biliary tract. Endoscopic sphincterotomy of the papilla of Vater may provide symptomatic relief for patients with papillary stenosis. Opportunistic infections within the pancreas gland have been documented in both pre- and postmortem studies. However, the true incidence of pancreatitis related to infections is unknown. The presentation is similar to that of pancreatitis from other causes. A computerized tomogram of the abdomen is the investigation of choice. Tissue aspiration or biopsy of the pancreas is required to demonstrate the presence of an opportunistic infection. The management is usually supportive, as it is rare that a specific infection is identified and treated.

Although the hazards of using Demerol for pain management is well documented, physicians at a 350-bed tertiary-care center in the upper midwest continued to follow the antiquated practice of ordering intramuscular Demerol and Vistaril to manage pain for patients with acute pancreatitis. Their reasoning was based on early evidence that Demerol, unlike morphine, does not cause biliary-tract spasms resulting in epigastric or right upper quadrant pain. In an effort to change practice patterns, a multidisciplinary team was formed to study the efficacy of using Transdermal Therapeutic System (TTS) fentanyl to manage pain in this patient population. Thirty-two subjects were enrolled in a double-blind, placebo-controlled study to evaluate the efficacy of using TTS fentanyl with intramuscular Demerol for breakthrough pain in comparison to using a placebo system and intramuscular Demerol. There was no statistically significant difference in self-reported pain intensity between the control and experimental groups on the first day of hospitalization. This finding would be expected because serum fentanyl concentrations rise gradually during the first 12 to 14 hours after application of the TTS fentanyl and plateau at 24 hours. There was a statistically significant difference between groups at 36 hours (exact p <.0154) and 45 hours (exact p <.0132) after application of the TTS fentanyl. This is probably because of greater serum fentanyl concentrations observed during the 36- to 48-hour period after application of TTS fentanyl. Although not statistically significant, trends in the data revealed that the experimental group had lower self-reported pain intensity scores than the control group throughout the course of hospitalization. Even though the experimental group had significantly more previous hospitalizations for acute pancreatitis and a higher pain intensity score on admission, this group had a significantly shorter length of stay in the hospital c2 (1, N = 31) = 4.3706 p <.05. There was no statistically significant difference between the two groups for self-reported satisfaction with pain management.

Pleuropulmonary amebiasis is the common and pericardial amebiasis the rare form of thoracic amebiasis. Low socioeconomic conditions, malnutrition, chronic alcoholism, and ASD with left to right shunt are contributing factors to the development of pulmonary amebiasis. Although no age is exempt, it commonly occurs in patients aged 20 to 40 years, with an adult male to female ratio of 10:1. Children rarely develop thoracic amebiasis: when it does occur there is an equal sex distribution. The infection usually spreads to the lungs by extension of an amebic liver abscess. Infection may pass to the thorax directly from the primary intestinal lesion through hematogenous spread, however. Lymphatic spread is one possible route. Inhalation of dust containing cysts and aspiration of cysts or trophozoites of E histolytica in the lungs are some other hypothetical routes. The lung is the second most common extraintestinal site of amebic involvement after the liver. Usually the lower lobe, and sometimes the middle lobe of the right lung, are affected, but it may affect any lobe of the lungs. The patient develops fever and right upper quadrant pain that is referred to the tip of the right shoulder or in between the scapula. Hemophtysis is common. The diagnosis of thoracic amebiasis is suggested by the combination of an elevated hemidiaphragm (usually right), hepatomegaly, pleural effusion, and involvement of the right lung base in the form of haziness and obliteration of costophrenic and costodiaphragmatic angles. Infection is usually extended to the thorax by perforation of a hepatic abscess through the diaphragm and across an obliterated pleural space, producing pulmonary consolidation, abscesses, or broncho-hepatic fistula. Empyema develops when a liver abscess ruptures into the pleural space. Rarely, a posterior amebic liver abscess can burst into the inferior vena cava and develop an embolism of the inferior vena cava and thromboembolic disease of the lungs with congestive cardiac failure or corpulmonale. Diagnosis by finding E histolytica in stool specimens is of limited value. In a limited number of cases amebae might be found in aspirated pus or expectorated sputum. "Anchovy sauce-like" pus or sputum may be found. Presence of bile in sputum indicates that the pus is of liver origin. Serological tests are of immense value in diagnosis. Liver enzymes are usually normal and neutrophilic leucocytosis may or may not be found. ESR is invariably elevated. Anti-amebic antibodies can be detected by ELISA, IFAT, and IHA. Amebic antigen can be detected from serum and pus by ELISA. Detection of Entamoeba DNA in pus or sputum may be a sensitive and specific method. Pleuropulmonary amebiasis is easily confused with other illnesses and is treated as pulmonary TB, bacterial lung abscesses, and carcinoma of the lung. A single drug regimen with metronidazole with supportive therapy usually cures patients without residual anomalies. Aspiration of pus from empyema thoracis may be needed for confirmation and therapeutic purposes. The pericardium is usually involved by direct extension from the amebic abscess of the left lobe of the liver, sometimes from the right lobe of the liver, and rarely from the lungs or pleura. An initial accumulation of serous fluid due to reactive pericarditis followed by intrapericardial rupture may develop either (1) acute onset of severe symptoms with chest pain, dyspnea, and cardiac tamponade, shock, and death, or (2) progressive effusion with thoracic cage pain, progressive dyspnea, and fever. Chest radiograph, ultrasound examination, and CT scan usually confirm the presence of a liver abscess in continuity with the pericardium and fluid within the pericardial sac with or without the fistulous tract. Echocardiography may demonstrate fluid in the pericardial cavity. Patients should be cared for in the ICU and ambecides should be started without delay. Pericardiocentesis usually confirms the diagnosis and improves the general condition of the patient. Aspiration of the accumulated fluid should be performed urgently in cardiac tamponade; repeated aspiration may be needed. Surgical drainage should be done if needed. Acanthamoeba, a free-living ameba, may also infect the lungs in the form of pulmonary nodular infiltration and pulmonary edema in association with amebic meningoencephalitis in immunocompromised patients. It usually spreads to the meninges of the brain by way of the blood from its primary lesion in the lung or skin. Early diagnosis and institution of treatment may be life saving for these patients. A literature review shows that HIV/AIDS patients are not prone to infection with E histolytica. It is now clear that there are an increasing number of HIV-seropositive patients among amebic liver abscess patients, however, which suggests that although the incidence of intestinal infection is not high among HIV-seropositive or AIDS patients they are more susceptible to an invasive form of the disease.

Chronic acalculous cholecystitis is a diagnosis of exclusion in patients complaining acalculous biliary pain. The possible causes of acalculous biliary pain are chronic gallbladder (GB) inflammation, GB dysfunction, cholesterolosis, cystic duct stenosis or microlithiasis. Recently, laparoscopic cholecystectomy is the choice of treatment for acalculous biliary pain. We experienced a 32-year-old woman whose initial symptoms were right upper quadrant pain and nausea only. The abdominal computed tomography, DISIDA scan, and upper and lower endoscopic examinations were nonspecific. Up to 48 hours after endoscopic retrograde cholangiopancreatography, contrast emptying of GB was delayed, implying dysfunctional GB. As the patient's right upper quadrant pain and tenderness became aggravated, the laparoscopic cholecystectomy was done and the final diagnosis of chronic acalculous cholecystitis was confirmed.

Fitz-Hugh-Curtis syndrome has been defined as perihepatitis accompanying pelvic inflammatory disease caused by Neisseria gonorrhoeae and Chlamydia trachomatis. In the acute phase, patients usually complain of severe right upper quadrant pain of sudden onset. The pain is sharp, pleuritic and most intense at the level of the right lower rib margin and thus it is frequently confused with acute cholecystitis or pleurisy. Definitive diagnosis of Fitz-Hugh-Curtis syndrome needs invasive procedures such as laparoscopy or laparotomy, but considering that Fitz-Hugh-Curtis syndrome is a benign condition that can be cured by oral administration of appropriate antibiotics, noninvasive diagnosis is desirable. Recently, we have experienced two cases of Fitz-Hugh-Curtis syndrome in acute phase accompanied with sharp and pleuritic right upper quadrant pain. In one case, pelvic inflammatory disease was not definite, so at first we mistook it for acute cholecystitis and reactivation of chronic hepatitis B. In the other case, Fitz-Hugh-Curtis syndrome followed the preceding, typical pelvic inflammatory disease. Both cases were diagnosed noninvasively and treated successfully by oral administration of antibiotics.

Advancements in laparoscopic surgery have resulted in decreased length of hospitalization, reduced postoperative pain, and better cosmesis following general surgical procedures. Carbon dioxide gas embolism is a rare occurrence that can be fatal. We report the case of a patient with a venous gas embolism during laparoscopic cholecystectomy. A 63-year-old woman presented with intermittent right upper quadrant pain, and her abdominal ultrasound showed a possible gallbladder polyp. A laparoscopic cholecystectomy was planned. A Veress needle was placed in the right upper quadrant to initiate abdominal access. Shortly after carbon dioxide insufflation, the patient's hemodynamic status deteriorated, her oxygen saturation dropped, and her end-tidal CO2 decreased. Gas insufflation was immediately stopped, and the patient was resuscitated. She stabilized quickly, and the procedure was performed without further event. She did well postoperatively and was discharged home the next day. Carbon dioxide embolism during laparoscopy, albeit rare, can be a fatal complication of the procedure. Whenever sudden changes in hemodynamic stability occur, venous gas embolism should be considered. As laparoscopic techniques and applications are expanded, the general surgeon must be aware of this entity.

Serious abdominal injuries in athletics, including liver trauma, are relatively rare. When they do occur, the athletic trainer and the team physician must be able to recognize the signs and symptoms and employ the appropriate first aid and follow-up care. In this paper, we present a case study of a football player who suffered a lacerated liver as a result of a forceful blow to the right side of the chest. Although his case was typical of most isolated liver injuries and he did not experience massive internal bleeding, the potential for life-threatening exsanguination exists and must be recognized by by sports health care practitioners. Most isolated liver injuries can be treated nonsurgically. However, those patients with multiple organ trauma, deteriorating vital signs, or diminishing hemodynamic stability generally require immediate surgery. Athletes with persistent right upper quadrant pain, especially when accompanied by referred pain to the right shoulder, abdominal rigidity, guarding, or rebound pain should be considered to have a liver injury until ruled out by CT scan and liver enzyme studies. Our subject was typical of most athletic liver patients and he was able to resume light exercise after 5 weeks and full activity after 3 months.

Acute abdominal pain can represent a spectrum of conditions from benign and self-limited disease to surgical emergencies. Evaluating abdominal pain requires an approach that relies on the likelihood of disease, patient history, physical examination, laboratory tests, and imaging studies. The location of pain is a useful starting point and will guide further evaluation. For example, right lower quadrant pain strongly suggests appendicitis. Certain elements of the history and physical examination are helpful (e.g., constipation and abdominal distension strongly suggest bowel obstruction), whereas others are of little value (e.g., anorexia has little predictive value for appendicitis). The American College of Radiology has recommended different imaging studies for assessing abdominal pain based on pain location. Ultrasonography is recommended to assess right upper quadrant pain, and computed tomography is recommended for right and left lower quadrant pain. It is also important to consider special populations such as women, who are at risk of genitourinary disease, which may cause abdominal pain; and the elderly, who may present with atypical symptoms of a disease.

Fasciola hepatica, a liver fluke of livestock, rarely presents as chronic biliary tract infection in humans. We report a 38-year-old woman from Ethiopia who presented with right upper quadrant pain and a dilated common bile duct on ultrasound and magnetic resonance cholangiopancreatography (MRCP) without other abnormalities. She was suspected to have type II sphincter of Oddi dysfunction. She underwent endoscopic retrograde cholangiopancreatography (ERCP) and had a fluke, diagnosed as Fasciola hepatica, in the common hepatic duct. This report confirms the diagnostic and therapeutic role of ERCP in the management of biliary fascioliasis, and highlights the need to include fascioliasis in the differential diagnosis of biliary pain in patients emigrating from areas where this infection is endemic.
