Cholecystectomy and cholelithiasis in sickle cell anemia

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.

Outcome of cholelithiasis in Sudanese children with Sickle Cell Anaemia (SCA) after 13 years follow-up

BACKGROUND

SCA causes chronic haemolysis which is a risk factor for cholelithiasis.

OBJECTIVE

To determine the prevalence and outcome of children with SCA complicated with gallstones treated at the sickle cell clinic at the children emergency hospital Khartoum state.

METHODS

261 patients age 4 months to 16 years were studied. AUS examination was carried out. The 30 patients in whom gall stones were detected followed prospectively from June 1996 to September 2009 when a second AUS examination was obtained.

RESULTS

Gall stones occurred in 30 patients of whom four were lost to follow up in the first year. The overall prevalence of cholelithiasis was 11.5% and it increased with age. The youngest patient with cholelithiasis was 2 1/2 years old. Haematological variables, bilirubin and sex did not identify a subgroup of patients at higher risk for gallstones. All the patients were asymptomatic at the time of diagnosis. One patient developed symptoms 3years after the diagnosis and he was submitted to surgery. The 25 remaining asymptomatic patients were followed up for 13 years and none of them presented complications related to cholelithiasis during this period.

CONCLUSION

The prevalence of cholelithiasis in Sudanese children and adolescents with SCA was significant. The large majority patients remained asymptomatic over a long period.

Elective laparoscopic cholecystectomy

BACKGROUND

Gallbladder stones are very common in patients with sickle cell disease and are the cause of recurrent abdominal pain. Their management has been highly controversial, especially for children. Nonoperated patients and those treated on an emergency basis have a very high rate of morbidity (>50%).

METHODS

We performed a retrospective review of a series of 29 homozygous SS sickle cell children who underwent laparoscopic cholecystectomy between 1991 and April 1998.

RESULTS

Only in one case a conversion was necessary (early in the series). Exploration of the common bile duct was done via intraoperative cholangiography. There were no mortalities. The morbidity rate was 17%; (however, of the five patients concerned, four suffered from hyperthermia for 2 days. All of the children were improved and enjoyed resolution of their abdominal pain.

CONCLUSIONS

We believe that elective laparoscopic cholecystectomy at the earliest time possible, along with correct perioperative management, is the treatment of choice for cholelithiasis in children with sickle cell disease.
