Hepatic dysfunction is a common finding in patients with sickle cell disease but viral hepatitis appears to be an unusual complication in the adult SS patient. Only five cases of viral hepatitis were recorded in 378 admissions for SS crisis. In contrast, hepatic crisis occurred as a distinct event in 9% of 88 patients with sickle cell anemia. This entity must be differentiated from acute cholecystitis or viral hepatitis. Transiently abnormal results of hepatitic function tests were observed in another 26 patients with extrahepatic crisis. Cirrhosis is relatively common and often the terminal event in SS disease. Choledocholithiasis and cholecystitis are infrequent complications despite the prevalence of gallstones in SS anemia.

Sickle hemoglobinopathies include sickle cell disease, sickle-C disease, and sickle-beta thalassemia. Patients with these disorders commonly suffer a multitude of destructive events to vital organs, especially to the central nervous system, the spleen, the kidney, the lung, and the heart as a result of microvascular plugging by the sickled erythrocytes. Thoughtful preparation for anesthesia and operation, especially when directed by experienced individuals, can greatly reduce the hazard of inducing the sickle crises that formerly plagued individuals with sickle hemoglobinopathies who faced major operations under general anesthesia. The patient must be free of any acute illness, especially one involving the respiratory system. Adequate hydration preoperatively combined with avoiding perioperative hypoxia, hypothermia, and acidosis, the triggers for sickling, will go far toward avoiding sickle-induced complications. Modern transfusion therapy, consisting of multiple small transfusions of Hb A erythrocytes administered over several weeks prior to the operation, not only corrects the chronic anemia but suppresses erythropoiesis of cells containing Hb S in the patient's bone marrow and leaves him or her with a majority of cells containing Hb A. This provides a safety net in case a sickle-inducing insult occurs despite the best efforts to avoid one. Individuals with sickle hemoglobinopathies may require any of the operations common to all children, for example, herniorrhaphy, appendectomy, tonsillectomy, and circumcision, but a significant number will develop calcium bilirubinate cholelithiasis and possibly cholecystitis as a result of the continual increased load of bile salts resulting from the shortened lifespan of the cells containing Hb S. Also, although most individuals with Hb S will gradually suffer splenic infarction by late childhood, a significant number of infants will experience acute splenic sequestration crisis, a life-threatening entity, the recurrence of which is prevented by splenectomy. Several publications have demonstrated that such surgical procedures can be performed in large numbers of patients with sickle hemoglobinopathies without deaths and with minimal morbidity.

In three adults with acute leukaemia, acalculous cholecystitis was diagnosed with ultrasonography soon after bone marrow transplantation. The clinical picture of cholecystitis was progressive, and cholecystectomy was performed in all cases despite anaemia, granulocytopenia and thrombocytopenia. Postoperative recovery was uncomplicated.

Melanoma frequently disseminates to the gastrointestinal tract, being found post-mortem in 60 per cent of patients with disseminated disease, while during life it is diagnosed in only 4 per cent. During the period 1981-87, 835 melanoma patients were referred and 30 developed complaints caused by gastrointestinal metastatic melanoma. Twenty-three patients were treated surgically. The interval between treatment of the primary melanoma and detection of intestinal involvement was a median of 34 months (range 2-87 months). In four patients recurrence in the gut was the first evidence of dissemination. Major complaints were nausea and vomiting, abdominal pain, signs of anaemia, and blood in the stools. Complications were bleeding (ten cases), ileus due to intussusception (five cases), bowel perforation (four cases) and cholecystitis (one case). The metastases, mainly localized in the small bowel, were removed by relatively simple procedures. Symptoms were reduced in 19 patients. Two patients died after operation: one from sepsis due to suture leakage, the other from pneumonia and a cerebrovascular accident. Of the remaining patients, 16 survived a median of 7.5 (range 0.7-32.0) months. Five patients are still alive 72, 72, 70, 7 and 2 months after the metastasectomy, three of whom are tumour-free. The actuarial 5-year survival of all patients is 19 per cent. These results support surgical intervention for patients with complaints and/or complications attributable to gastrointestinal metastatic melanoma.

Chile is the country with the highest incidence of gallstone disease in the world. Nearly 44% of the women and 25% of the men over 20 years of age have gallstones. Biliary tract surgery accounts for about 35% of all the operations performed in Chilean general hospitals. The present paper aims at assessing the risk factors associated with a higher mortality in patients over 70 years of age subjected to elective or emergency surgery for gallstones or common bile duct stones. No specific factors of mortality were found in the group of elderly patients subjected to elective cholecystectomy. There was also no correlation between types of cholecystitis and postoperative mortality. However, acute suppurative cholangitis made the postoperative mortality rate increase almost 20-fold in patients with common bile duct stones. The mortality also shows a steep increase (up to 12%) if cholecystectomy is performed in acute cholecystitis. Cholecystostomy seems to be associated with a low mortality risk and hence should be appropriate in exceptionally high-risk patients, but is not considered useful by the authors in necrotic or gangrenous cholecystitis, or in cases with common bile duct stones and cholangitis. Postoperative mortality in patients submitted to cholecystectomy alone seems to depend exclusively on the concomitant presence of medical complications, mainly of a respiratory and cardiovascular nature. Septic complications are important causes of postoperative mortality in emergency cholecystectomy. Patients at high surgical risk are those suspected of cholangitis, those over 80 years of age, and those suffering from Charcot's triad, anemia, uremia, leukocytosis, hyperbilirubinemia or hypoprothrombinemia; in these, an endoscopic procedure could be chosen.

Sickle crises frequently manifest as abdominal pain that may simulate intra-abdominal infection. To establish parameters to distinguish these, we retrospectively studied 53 patients with sickle-cell anemia who had abdominal pain (genotype SS 62%, SC 15%, SA 11%, S-other 11%; 30% men and 70% women; mean age 23). A vaso-occlusive crises was responsible for the pain in 57 per cent; 23 per cent had a surgical entity and 20 per cent had a nonsurgical genitourinary disorder. Of the surgical conditions, 9 of 12 patients (95%) had cholecystitis and 4 of 12 patients (33%) had acute appendicitis (one patient had both). Vaso-occlusive crises were diffuse in 15 of 30 patients (50%), compared with proven surgical conditions, and was more often associated with remote pain such as limbs and chest (23 of 30 [77%] P less than 0.005). The pain of vaso-occlusive crises simulated prior crises in 21 of 30 patients (70%) compared with 1 of 12 patients (8%) who had surgical abdominal pain (P less than 0.005). A precipitating event (especially upper respiratory infection) was found in 50 per cent of abdominal vaso-occlusive crises versus 0 per cent of surgical abdomens (P less than 0.010). The pain was relieved with hydration and oxygen in 97 per cent of sickle crises within 48 hours versus 0 per cent of surgical abdomens (P less than 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)

In the past Actinomycosis has been associated with diverticular disease of the colon, abdominal surgery, cholecystitis, and penetrating trauma. Recent reports have demonstrated an increased incidence in women using IUDs. Such a case is presented. a 40-year-old woman experienced lower abdominal pain and a 20 pound weight loss over a 2 month period. The patient had had an IUD (a Dalkon shield) placed 7 years previously and had not sought medical attention since then. Pelvic examination revealed an IUD in place and an 8 cm mass fixed to the left side wall and displacing the rectum. The IUD was removed after the pelvic examination. Laboratory studies were all within normal limits except for mild anemia. A computed tomographic scan of the pelvis showed a left hydroureter, an 8 cm pelvic mass with left side wall extension, and displacement of the rectum to the right. A barium enema examination showed fixed narrowing of the rectum and mucosal irregularity. A fine needle aspiration biopsy showed endometritis and frank pus with the presence of Actinomyces. Surgery confirmed these findings. The patient responded to antibiotic therapy after surgery and did well. The colonization of the vagina, cervix, and uterus by Actinomyces and complications such as tubo-ovarian and pelvic abscesses have been reported in IUD users. 1 study reported Actinomyces in as many as 25% of IUD users, although all patients in that study were asymptomatic. In addition, this group had an increased incidence of abnormal pap smears, which may add a confusing note in the event of a pelvic mass. The association if IUD use and abscess appears increased in those patients who have had the same iud in place for more that 2 years, although the complication has been reported only 2 1/2 months following IUD insertion. Actinomycosis is a diagnosis seldom made before biopsy or surgery. Culture of the organism is essential and the diagnosis is best made using immunofluorescent staining of formaldehyde-fixed, paraffin-embedded tissue. This needle biopsy can provide a quick diagnosis. Therapy includes high dose penicillin, to which the disease responds quickly, and incision and drainage if necessary. Prompt diagnosis and adequate treatment reduce the morbidity of dissemination and of chronic infection.

Functional abnormalities of the liver uncovered during preoperative routine evaluation were analyzed in 109 donor candidates for 100 cases of living-related liver transplantation (LRLT) performed during the period from June, 1990 to May, 1994 at the Second Department of Surgery, Kyoto University Hospital. High serum transaminase (GOT, GPT) levels were noted in 10 (9.2%) cases among 109 candidates, high alkaline phosphatase in 4 (3.7%), hyperbilirubinemia in 3 (2.8%), anemia in 3 and high choline esterase in 3 cases. Positive hepatitis C antibody (HCV) was also noted in 1 case. Fatty liver was detected in 10 (9.2%) cases, cholecystitis in 2 cases, 1 case each of cyst and calcification in the liver by diagnostic imaging (ultra sonograph and/or computed tomography). These abnormalities of the liver necessitated replacing the initial candidate with the other parent in 9 cases, including 1 case without any functional abnormality whose graft liver was too large to fit the recipient abdominal cavity. There were 14 cases of ABO blood type incompatible combination. Switching the initial candidate due to these abnormalities mentioned above resulted in incompatible combinations in 4 of these 14 cases. Although the advantages of the LRLT are the superior viability of the donor graft and the genetic histocompatibility between recipient and donor, to optimize the advantage of LRLT, all donor candidates should be strongly advised to make every effort preoperatively to improve their physical condition in preparation for the LRLT protocol, since many of these abnormalities are typically reversible.

The authors report a case of massive hematobilia due to hemorrhagic cholecystitis. Hematobilia is a rare pathology which affects the biliary tract and gallbladder. The first authors to describe hematobilia defined it as a hemorrhage of the gastroenteric tract due to the communication of blood vessels with the intra and extra-hepatic biliary tract and in some rare cases to the communication of the branches of the cystic artery within the gallbladder wall. Sandblom, in particular, specified that bleeding must be within the biliary tract and not secondary to an enterobiliary fistula. In 55% of cases the pathogenesis of hematobilia is traumatic, whereas in the remaining 45% the cause may be attributed to a variety of pathologies. Trauma include both non-surgical and surgical traumas; in the first group the most frequent cause is hepatic trauma, although it is worth taking into account the presence of post-traumatic arteriobiliary fistulas, lesions of arterial vessel walls with subsequent necrosis and rupture within the biliary vessels. Surgical traumas comprise lesions caused by therapeutic or diagnostic transparenchymal manoeuvres (PTC, biopsy). Non-traumatic causes include pathologies of vascular, cholecystic, inflammatory-infective and neoplastic origin. Symptoms are varied and take the form of anemia, massive bleeding with the onset of jaundice and pain in the hypochondrium and sometimes the epigastrium, whereas enterorrhagia is manifested by melena and more rarely hematemesis. The diagnosis must be made as quickly as possible; mortality increases with the delay in controlling hemorrhage. Differential diagnosis must take into account other causes of enterorrhagia, obstructive jaundice and anemia.(ABSTRACT TRUNCATED AT 250 WORDS)

The clinical course of patients with hematological disease, especially after treatment, is often complicated by gastrointestinal infections. Between 1986 and 1990 a total of 18 patients affected with hematologic disease and presenting with an acute abdomen were admitted to the surgery department at the University of Rome "La Sapienza". Most patients were affected with acute or chronic myeloid leukemia (61%) and lymphoma. Five patients with acute appendicitis, three with necrotizing enterocolitis, three with spontaneous hemoperitoneum, three with cholecystitis, two splenic infarctions and two intestinal occlusions were diagnosed. Symptoms were often vague and non specific and blood counts revealed neutropenia in all but two patients, while anemia was characteristic in spontaneous hemoperitoneum and in neutropenic enterocolitis. Fungemia occurred in only two cases while bacteremia was present in seven. The most critical patients were those affected by neutropenic enterocolitis and acute cholecystitis. Sonography was meaningful in the diagnosis of hemoperitoneum, splenic infarct and acute cholecystitis. All patients underwent surgical procedures within 48 hours of admission to the department. In all cases peritoneal washing was performed and at least one peritoneal drainage was left. In all cases of necrotizing enterocolitis, intestinal resections, either ileal or colonic, were followed by an immediate anastomosis in two layers. Intensive hematological and antibiotic post surgical care was performed in all patients. Seven patients presented minor complications (38.8%), and only one died (5.5%). Emergency surgical treatment may be safely carried out in patients with hematological diseases presenting with an acute abdomen. Intensive postsurgical care is mandatory for the recovery of patients and the patient's critical condition should not be a deterrent to surgical intervention.
