Cholelithiasis in sickle cell anemia: surgical considerations

Management of the Sickle Cell Trait: An Opinion by Expert Panel Members

The number of individuals with the sickle cell trait exceeds 300 million worldwide, making sickle cell disease one of the most common monogenetic diseases globally. Because of the high frequency of sickle cell disease, reproductive counseling is of crucial importance. In addition, unlike other carrier states, Sickle Cell Trait (SCT) seems to be a risk factor for several clinical complications, such as extreme exertional injury, chronic kidney disease, and complications during pregnancy and surgery. This expert panel believes that increasing knowledge about these clinical manifestations and their prevention and management can be a useful tool for all healthcare providers involved in this issue.

Cholecystectomy for asymptomatic gallstones: Markov decision tree analysis

Gallstones are a common public health problem, especially in developed countries. There are an increasing number of patients who are diagnosed with gallstones due to increasing awareness and liberal use of imaging, with 22.6%-80% of gallstone patients being asymptomatic at the time of diagnosis. Despite being asymptomatic, this group of patients are still at life-long risk of developing symptoms and complications such as acute cholangitis and acute biliary pancreatitis. Hence, while early prophylactic cholecystectomy may have some benefits in selected groups of patients, the current standard practice is to recommend cholecystectomy only after symptoms or complications occur. After reviewing the current evidence about the natural course of asymptomatic gallstones, complications of cholecystectomy, quality of life outcomes, and economic outcomes, we recommend that the option of cholecystectomy should be discussed with all asymptomatic gallstone patients. Disclosure of material information is essential for patients to make an informed choice for prophylactic cholecystectomy. It is for the patient to decide on watchful waiting or prophylactic cholecystectomy, and not for the medical community to make a blanket policy of watchful waiting for asymptomatic gallstone patients. For patients with high-risk profiles, it is clinically justifiable to advocate cholecystectomy to minimize the likelihood of morbidity due to complications.

Prophylactic laparoscopic cholecystectomy in adult sickle cell disease patients with cholelithiasis: A prospective cohort study

INTRODUCTION

Prophylactic laparoscopic cholecystectomy remains controversial and has been discussed for selected subgroups of patients with asymptomatic cholelithiasis who are at high risk of developing complications such as chronic haemolytic conditions. Cholelithiasis is a frequent condition for patients with sickle cell disease (SCD). Complications from cholelithiasis may dramatically increase morbidity for these patients. Our objective was to evaluate the effectiveness of prophylactic cholecystectomy in SCD patients with asymptomatic gallbladder stones.

METHODS

From January 2000 to June 2014, we performed 103 laparoscopic cholecystectomies on SCD patients. Fifty-two patients had asymptomatic cholelithiasis. The asymptomatic patients were prospectively enrolled in this study, and all underwent a prophylactic cholecystectomy with an intraoperative cholangiography. The symptomatic patients were retrospectively studied. Upon admission, all patients were administered specific perioperative management including intravenous hydration, antibiotic prophylaxis, oxygenation, and intravenous painkillers, as well as the subcutaneous administration of low-molecular-weight heparin. During the same period, 51 patients with SCD underwent a cholecystectomy for symptomatic cholelithiasis. We compared these 2 groups in terms of postoperative mortality, morbidity, and hospital stay.

RESULTS

There were no postoperative deaths or injuries to the bile ducts in either group. In the asymptomatic group, we observed 6 postoperative complications (11.5%), and in the symptomatic group, there were 13 (25.5%) postoperative complications.

DISCUSSION

Regarding the SCD complications, we observed 1 case (2%) of acute chest syndrome in an asymptomatic cholelithiasis patient, while there were 3 cases (6%) in the symptomatic group. Vaso-occlusive crisis was observed in 1 patient (2%) with asymptomatic cholelithiasis, and in 4 patients (8%) in the other group. The mean hospital stay averaged 5.8 (4-17) days for prophylactic cholecystectomy and 7.96 (4-18) days for the comparative symptomatic group.

CONCLUSIONS

Postoperative complications related to SCD were less frequent for asymptomatic patients who had a laparoscopic prophylactic cholecystectomy. This intervention, if performed with perioperative specific management, is safe and helps avoid emergency operations for acute complications including cholecystitis, choledocholithiasis, and cholangitis. For SCD patients, a prophylactic cholecystectomy reduces hospital stays.

Acute liver function decompensation in a patient with sickle cell disease managed with exchange transfusion and endoscopic retrograde cholangiography

Sickle cell intrahepatic cholestasis is a relatively uncommon complication of homozygous sickle cell anemia, which may lead to acute hepatic failure and death. Treatment is mainly supportive, but exchange transfusion is used as salvage therapy in life threatening situations. We describe a case of a 16-year-old female with homozygous sickle cell anemia who presented to the emergency room with fatigue, malaise, dark urine, lower back pain, scleral icterus and jaundice. She was found to have marked hyperbilirubinemia, which persisted after exchange transfusion. Because of the concomitant presence of gallstones and choledocholithiasis, the patient underwent endoscopic ultrasound and laparoscopic cholecystectomy followed by endoscopic retrograde cholangiography and sphincterotomy.

Outcome and challenges of kidney transplant in patients with sickle cell disease

Sickle cell nephropathy is a common presentation in patients with sickle cell disease. End-stage kidney disease is the most severe presentation of sickle cell nephropathy in terms of morbidity and mortality. Sickle cell disease patients with end-stage kidney disease are amenable to renal replacement therapy including kidney transplant. Kidney transplant in these patients has been associated with variable outcome with recent studies reporting short- and long-term outcomes comparable to that of patients with HbAA. Sickle cell disease patients are predisposed to various haematological, cardiorespiratory, and immunological challenges. These challenges have the potential to limit, delay, or prevent kidney transplant in patients with sickle cell disease. There are few reports on the outcome and challenges of kidney transplant in this group of patients. The aim of this review is to highlight the outcome and challenges of kidney transplant in patients with sickle cell disease.

Anesthetic management of a patient with sickle β thalassemia

Sickle cell disease is a congenital condition and its most common clinical manifestation is anemia due to chronic hemolysis. Persistent and accelerated hemolysis associated with multiple transfusions is a recognized risk factor for the development of cholelithiasis. The occurrence of gallstones is one of the most important manifestations of sickle cell disease in the digestive tract. Most gallstones are pigmented and characteristically occur at younger ages and the prevalence of cholelithiasis increases progressively with age, affecting 50% of young adults. Cholecystectomy is the most common surgical procedure performed in sickle cell disease patients. Anesthesia in this population of patients for major surgeries deserves special attention due to various complications particularly silent infarctions of end organs are common. We are reporting a 14-year-old girl diagnosed with sickle cell anemia and β⁺ thalassemia with cholelithiasis went for cholecystectomy under general anesthesia. Although the patient has both β⁺ thalassemia and sickle cell disease component, the latter is of more concern for anesthesia.

Cholelithiasis in a toddler with sickle cell disease

Cholelithiasis is rarely seen in toddlers and school-aged children, even in the setting of sickle cell anemia. In addition to more common etiologies, such as gastroenteritis, constipation, and urinary tract infection, the differential diagnoses of acute abdominal pain in young children with sickle cell disease include vaso-occlusive pain crisis and splenic sequestration. We describe a case of a toddler with sickle cell disease initially presenting with abdominal pain who was found to have symptomatic cholelithiasis.

Gastrointestinal and hepatic complications of sickle cell disease

Sickle cell disease (SCD) is an autosomal recessive abnormality of the beta-globin chain of hemoglobin (Hb), resulting in poorly deformable sickled cells that cause microvascular occlusion and hemolytic anemia. The spleen is almost always affected by SCD, with microinfarcts within the first 36 months of life resulting in splenic atrophy. Acute liver disorders causing right-sided abdominal pain include acute vaso-occlusive crisis, liver infarction, and acute hepatic crisis. Chronic liver disease might be due to hemosiderosis and hepatitis and possibly to SCD itself if small, clinically silent microvascular occlusions occur chronically. Black pigment gallstones caused by elevated bilirubin excretion are common. Their small size permits them to travel into the common bile duct but cause only low-grade obstruction, so hyperbilirubinemia rather than bile duct dilatation is typical. Whether cholecystectomy should be done in asymptomatic individuals is controversial. The most common laboratory abnormality is an elevation of unconjugated bilirubin level. Bilirubin and lactate dehydrogenase levels correlate with one another, suggesting that chronic hemolysis and ineffective erythropoiesis, rather than liver disease, are the sources of hyperbilirubinemia. Abdominal pain is very common in SCD and is usually due to sickling, which resolves with supportive care. Computed tomography scans might be ordered for severe or unremitting pain. The liver typically shows sickled erythrocytes and Kupffer cell enlargement acutely and hemosiderosis chronically. The safety of liver biopsies has been questioned, particularly during acute sickling crisis. Treatments include blood transfusions, exchange transfusions, iron-chelating agents, hydroxyurea, and allogeneic stem-cell transplantation.

Sickle cell intrahepatic cholestasis with cholelithiasis

Sickle cell intrahepatic cholestasis (SCIC) is a rare complication seen in sickle cell patients who present with sudden onset of RUQ pain, progressive hepatomegaly, mild elevation of transaminases, coagulopathy, and extreme hyperbilirubinemia. Early recognition of this entity is essential to avoid life-threatening complications. Diagnosis can be challenging given the overlap in clinical presentation with other conditions affecting the hepatobiliary biliary system in sickle cell anemia such as hepatitis, cholecystitis, and hepatic crisis. Treatment is currently limited to exchange transfusion. The authors present two patients with SCIC and cholelithiasis; the clinical picture of one is complicated by choledocholithiasis.

Sickle cell 'girdle syndrome' progressing to ischaemic colitis and colonic perforation

Abdominal pain of presumed vasocclusive origin, often termed 'girdle syndrome' because of the circumferential distribution of the pain, is common in sickle cell anaemia (SCA). Evidence of progression to bowel infarction is rare. A 27-year-old man with SCA developed chest and abdominal pain unresponsive to opiate analgesia. Abdominal X-ray showed dilated bowel loops because of partial obstruction. Despite reduction of HbS to 23% by automated red cell exchange, abdominal pain worsened. A CT scan was the most informative investigation and showed free peritoneal air. He underwent emergency hemicolectomy and reversible ileostomy formation. Histology of the resected colon was consistent with acute ischaemic colitis. Early surgical intervention remains essential in SCA when abdominal pain does not respond to maximal therapy including red cell exchange: as this case illustrates, sickle girdle syndrome has the capacity to progress to irreversible ischaemic colitis and necrotic perforation of the bowel wall.

[Laparoscopic cholecystectomy in sickle cell disease]

STUDY AIM

Sickle cell affection is a public health problem in Africa. The aims of this prospective study were to evaluate the early results of laparoscopic cholecystectomy in sickle cell patients in Senegal.

METHOD

From January 1998 to June 2002 all the sickle cell patients undergoing a laparoscopic cholecystectomy were included. Intra- and post-operative protocol (blood transfusion if Hb < 9 g/dl, rehydration, oxygenotherapy) was standardized.

RESULTS

Forty-two patients with sickle cell of types SS-33 and AS9 were operated upon by same surgeon. One case of conversion due to an effraction of biliary junction was reported. One homozygote patient died post-operatively because of peritonitis. Two acute thoracic syndromes, three vaso-occlusive crisis, and two cases of wound infection constituted the post-operative morbidity. No case of complication was noted in those who underwent pre-operative transfusion.

CONCLUSION

Laparoscopic cholecystectomy can be carried out in sickle cell patients with biliary lithiasis provided that general anaesthetic rules are respected.

Anaesthetic management of the child with sickle cell disease

Sickle cell disease (SCD) is a relatively common inherited disorder of haemoglobin with significant morbidity and mortality. This review describes the epidemiology and pathophysiology of the disease, and discusses the clinical manifestations found in children with SCD. A discussion of the evidence concerning the perioperative management of such children is presented.

Laparoscopic cholecystectomy in adults with sickle cell disease

BACKGROUND

Chronic hemolysis predisposes adults with sickle cell disease (SCD) to the formation of bilirubinate cholelithiasis.

METHODS

To study the impact of laparoscopic cholecystectomy (LC) on this groups, we reviewed our records of all patients with SCD and cholelithiasis treated electively from 1991 to 1999. During that period, 13 consecutive patients with SCD underwent elective LC for symptomatic cholelithiasis. Nine patients (69.2%) were managed with a preoperative transfusion regimen to achieve a hemoglobin value of >/=10 g/dl, independent of hemoglobin S percentage. Five patients who presented with jaundice were referred for preoperative endoscopic retrograde cholangiopancreatography (ERCP), which identified choledocholithiasis in two of them. Three other patients underwent intraoperative cholangiography, which revealed common bile duct stones in one patient.

RESULTS

One patient developed pyrexia for 2 days. There were no vaso-occlusive crises or deaths. The mean hospital stay was 3.3 days.

CONCLUSIONS

LC has proven to be a safe and efficacious method for the treatment of symptomatic cholelithiasis in this high-risk population. Hematologists are now more willing to refer early, well-prepared patients with SCD and uncomplicated gallbladder disease for elective LC.

Gallstones in sickle cell disease: observations from The Jamaican Cohort study

The prevalence, incidence, risk factors, clinical associations, and morbidity of gallstones were studied in 311 patients with homozygous sickle cell disease and 167 patients with sickle cell-hemoglobin C disease in a cohort study from birth. Gallstones developed in 96 patients with homozygous sickle cell disease and 18 patients with sickle cell-hemoglobin C disease; specific symptoms necessitating cholecystectomy occurred in only 7 patients with homozygous sickle cell disease.

Surgery in patients with hemoglobin SC disease. Preoperative Transfusion in Sickle Cell Disease Study Group

While surgery is commonly required for complications related to hemoglobin SC (HbSC) disease, little is known about the perioperative complications or the indications for preoperative transfusion in this group. We describe the patient characteristics, preoperative transfusion regimens, and outcome in 92 patients with HbSC and sickle-variants undergoing elective surgery. Thirty-eight percent of the patients were transfused preoperatively. Patients transfused were more likely to have been hospitalized in the year prior to the surgery and scheduled for abdominal procedures. Abdominal and ear, nose and throat procedures were the most common surgeries in our study. The overall complication rate was 18% and sickle cell-related complications occurred in 9% of patients. In patients undergoing intra-abdominal procedures, the incidence of sickle cell-related complications was significantly higher in those patients not transfused prior to their surgery (35 vs. 0%). There were two deaths. We recommend selective use of preoperative transfusion in patients with HbSC disease undergoing surgery. Transfusion appears to be beneficial in abdominal cases but is not necessary with minor procedures such as myringtomy.

A comparison of conservative and aggressive transfusion regimens in the perioperative management of sickle cell disease. The Preoperative Transfusion in Sickle Cell Disease Study Group

BACKGROUND

Preoperative transfusions are frequently given to prevent perioperative morbidity in patients with sickle cell anemia. There is no consensus, however, on the best regimen of transfusions for this purpose.

METHODS

We conducted a multicenter study to compare the rates of perioperative complications among patients randomly assigned to receive either an aggressive transfusion regimen designed to decrease the hemoglobin S level to less than 30 percent (group 1) or a conservative regimen designed to increase the hemoglobin level to 10 g per deciliter (group 2).

RESULTS

Patients undergoing a total of 604 operations were randomly assigned to group 1 or group 2. The severity of the disease, compliance with the protocol, and the types of operations were similar in the two groups. The preoperative hemoglobin level was 11 g per deciliter in group 1 and 10.6 g per deciliter in group 2. The preoperative value for hemoglobin S was 31 percent in group 1 and 59 percent in group 2. The most frequent operations were cholecystectomies (232), head and neck surgery (156), and orthopedic surgery (72). With the exception of transfusion-related complications, which occurred in 14 percent of the operations in group 1 and in 7 percent of those in group 2, the frequency of serious complications was similar in the two groups (31 percent in group 1 and 35 percent in group 2). The acute chest syndrome developed in 10 percent of both groups and resulted in two deaths in group 1. A history of pulmonary disease and a higher risk associated with surgery were significant predictors of the acute chest syndrome.

CONCLUSIONS

A conservative transfusion regimen was as effective as an aggressive regimen in preventing perioperative complications in patients with sickle cell anemia, and the conservative approach resulted in only half as many transfusion-associated complications.

Perioperative management for cholecystectomy in sickle cell disease

Perioperative complications of surgical procedures are frequently encountered in patients with sickle cell disease. We have reviewed our series of patients with hemoglobinopathies who underwent cholecystectomy from 1978 to 1991 to evaluate their perioperative management and clinical outcome. Twenty-two children with major sickle hemoglobinopathy underwent cholecystectomy for symptomatic cholelithiasis. All 22 were transfused to achieve a hemoglobin (Hgb) level greater than 9 g/dL and hemoglobin S (HbS) less than 37%. Fourteen underwent immediate preoperative automated red cell exchange (ARCE). The median preexchange Hgb of these patients was 8.1 g/dL (range, 6.8 to 10.5). Their median HbS was 84% (range, 53% to 97%). These patients underwent placement of an apheresis catheter under local anesthesia followed by red cell exchange. The median volume of packed red blood cells (PRBC) exchanged was 28.1 mL/kg (range, 13.8 to 58.7). The median HbS after exchange was 21% (range, 16% to 37%) and the median Hgb was 10.6 g/dL (range, 6.5 to 16.7). Eight other patients underwent sequential transfusion (3 after an exchange for an acute pulmonary vasoocclusive crisis). These patients had been prepared over an interval of 2 to 8 weeks preoperatively and had received a median of 26.9 mL PRBC/kg (range, 12.8 to 95). Following sequential transfusion the median Hgb was 11.8 g/dL (range, 9 to 15.7) and the median HbS was 19% (range, 5% to 32%) at the time of surgery. All patients received extended antigen matched blood. Complications of preoperative transfusion were minor and included two febrile-/allergic reactions and one mild superficial catheter-induced phlebitis.(ABSTRACT TRUNCATED AT 250 WORDS)

Laparoscopic cholecystectomy in young patients with sickle hemoglobinopathies

Nine young patients with sickle hemoglobinopathies successfully underwent laparoscopic cholecystectomy; no complications resulted from the procedure. The mean postoperative hospital stay was 1.6 days. This technique appears to be a safe and efficacious procedure in children with sickle hemoglobinopathies who require cholecystectomy for cholelithiasis.

Experience of splenectomy and cholecystectomy in children with chronic haemolytic anaemia

Since 1973, 419 children (233 boys, 186 girls) with chronic haemolytic anaemia (mean age, 10.2 +/- 3.5 years) have been splenectomised. Fifty-three (12.6%) have also been cholecystectomised because of cholelithiasis. Between 1973 and 1982, cholecystectomy and splenectomy were performed at the same time in symptomatic patients. Later, between 1983 and 1987, cholecystectomy was also performed in clinically asymptomatic patients with positive sonographic findings. In the first period, 11 thalassaemic patients (45.8%) were cholecystectomised a short period after splenectomy (in two cases, only 2 and 3 weeks later). Between 1983 and 1987, when asymptomatic patients with cholelithiasis were screened by sonography, simultaneous cholecystectomy and splenectomy were performed in 13.6% of the patients with thalassaemia, in 41% of the patients with sickle cell or microdrepanocytic disease, and in 22.2% of the patients with spherocytosis. As there is a high incidence of asymptomatic cholelithiasis and hypersplenism in patients with chronic haemolytic anaemia, screening for gallstones should precede splenectomy. Simultaneous cholecystectomy should be performed in patients with cholelithiasis.

Elective cholecystectomy in children with sickle hemoglobinopathies. Successful outcome using a preoperative transfusion regimen

Twenty-seven children with major sickle hemoglobinopathies underwent elective cholecystectomy for cholelithiasis. All were managed with a preoperative transfusion regimen to achieve a hemoglobin concentration of 11-14 g/dl with greater than 65% hemoglobin A. Intraoperative cholangiography revealed common bile duct stones in five patients, although only one case was diagnosed by preoperative ultrasonographic examination. Twenty-four children underwent incidental appendectomy by total intussusception. There were no vaso-occlusive events nor any other perioperative morbidity or mortality. Four months after cholecystectomy, one boy had a small bowel obstruction requiring surgical re-exploration. No patients had transfusion-acquired infection, although one boy had erythrocyte allosensitization to Lewis A antigen. This preoperative transfusion regimen and careful perioperative management permits safe elective cholecystectomy in children with sickle cell disease.

Gall stones in sickle cell disease in the United Kingdom

The prevalence of gall stones was studied prospectively by abdominal ultrasound examination in 131 patients with sickle cell disease aged 10-65 years. Of 95 patients with homozygous sickle cell disease, 55 (58%) had gall stones or had had a cholecystectomy. Gall stones were present in four out of 24 (17%) patients with haemoglobin S + C disease and two out of 12 (17%) with haemoglobin S beta thalassaemia. The presence of gall stones was not related to sex, geographical origin, or haematological variables and was not associated with abnormal results of liver function tests. Symptoms typical of biliary colic were reported by 32 out of 47 adult patients with gall stones, and cholecystitis or cholestasis was diagnosed in 18. Cholecystectomy was performed in 29 patients with good relief of symptoms in most cases. Postoperative complications were common, occurring in 10 of the 28 patients who could be evaluated, but not generally serious; they were considerably lessened by a preoperative exchange transfusion that reduced the haemoglobin S concentration to below 40%. It is suggested that all patients with sickle cell disease should be screened for gall stones and that elective cholecystectomy should be performed in those with symptoms or complications.
