Postcholecystectomy syndrome with special regard to children--a review

Treatment of asymptomatic gallstones in children with hereditary spherocytosis requiring splenectomy

BACKGROUND

Gallstones are common in hereditary spherocytosis (HS) and other chronic hemolytic diseases, with most affected patients being asymptomatic. Whether and how asymptomatic gallstones should be treated is controversial.

METHODS

We conducted a retrospective cohort study of pediatric patients with HS and asymptomatic gallstones to compare the clinical outcomes between the observation group (followed up with gallstones in situ) and the intervention group (cholecystectomy or cholecystolithotomy). The primary outcome was the composite of adverse outcomes, including gallstone-associated, gallbladder surgery-associated, and splenectomy-associated events. Secondary outcomes included the changes in the size and number of gallstones and the recurrence of gallstones.

RESULTS

Fifty-two patients were included (38 in the observation group and 14 in the intervention group), with a mean follow-up length of 5.2 years. Patients in the intervention group had a lower incidence of primary outcomes (7.1% vs. 42.1%) than patients in the observation group (OR, 0.12; 95%CI, 0.01-0.99). Patients with gallstones >5 mm in diameter had the highest risk of adverse events (47.4%). In the observation group, gallstone growth, disappearance, and stability were observed in 19.4%, 29.0%, and 51.6% of splenectomized HS patients, respectively. Small gallstones (diameter ≤5 mm) or sludge were more likely to be associated with disappearance (P = 0.04).

CONCLUSIONS

Most asymptomatic gallstones grow or persist in splenectomized HS patients for an extended period. Surgical treatment of asymptomatic gallstones in HS patients requiring splenectomy is associated with a lower risk of adverse outcomes.

Post-cholecystectomy syndrome in pediatric patients: Occurrence and spectrum of symptoms

BACKGROUND

Post-cholecystectomy syndrome (PCS) refers to persistent or new abdominal symptoms after cholecystectomy. As there are very few reports on PCS in pediatric patients, we aimed to examine whether it was a frequent finding and which symptoms the affected children experienced.

METHOD

This is a retrospective cross sectional study of pediatric patients, who underwent cholecystectomy during 2003-2019 at Oslo University Hospital. The PedsQL™ gastrointestinal symptoms scale questionnaire and a self-designed questionnaire exploring satisfaction after surgery and current medical conditions were mailed to all eligible patients. Patient/parental consent and approval from the local data protection officer (19/09054) were obtained.

RESULTS

Questionnaires were sent to 82 patients of whom 44 (54%) answered. There were no significant demographic differences between the responders and the non responders. We identified 16 (36.7%) patients to have PCS. The most common symptoms were diarrhea (25%), bloating (16%), and heartburn/reflux (16%). Overweight was more common in patients with PCS (31%) than in patients without PCS (4%) (p = 0.014). Altogether 34/44 (77.3%) patients were satisfied with the result of the cholecystectomy; 92,6% of patients without PCS and 56.6% of those with PCS (p = 0.012).

CONCLUSION

PCS is not uncommon in pediatric patients, and they report a wide range of gastrointestinal symptoms. We identified overweight as a potential risk factor for developing PCS. Nonetheless, most patients got total relief of abdominal pain and were satisfied with outcome after cholecystectomy.

Systemerkrankungen

Systemerkrankungen als Ursache einer Lebererkrankung sind häufig, ohne dass man genaue Zahlen angeben kann. Die verschiedenen Grunderkrankungen sind für sich betrachtet zwar selten, nur dadurch, dass viele Erkrankungen in Betracht gezogen werden müssen, ergibt sich eine relative Häufung. Durch Fortschritte auf dem Gebiet der molekularbiologischen Diagnostik insbesondere bei den Stoffwechselerkrankungen lassen sich heute bereits viele der in Frage kommenden Grunderkrankungen eindeutig nachweisen. Allerdings ist bei keiner der Erkrankungen ein hundertprozentiger molekularbiologischer Nachweis möglich. Damit ergibt sich eine sichere Diagnose nur bei einem positiven Nachweis. Bei fehlendem Nachweis einer bisher bekannten für die Erkrankung spezifischen Mutation bleibt die Zuordnung entweder enzymatischen Tests oder klinischer Diagnose vorbehalten. Insbesondere bei der Manifestation als akutes Leberversagen ist die für die Diagnosesicherung erforderliche Zeit damit oft nicht vorhanden.

Surgical treatment of inspissated bile syndrome using a 2-stage pure laparoscopic approach: a case report

We describe a 99-day old girl with inspissated bile syndrome (IBS) unresponsive to treatment with oral ursodeoxycholic acid. We performed a pure laparoscopic 2-stage procedure, consisting of cholecystostomy and insertion of an indwelling balloon catheter for local ursodeoxycholic acid flushing for 13 consecutive days. Subsequently, the cholecystostomy was removed, preserving the gallbladder using the same laparoscopical approach when bilirubin values returned to normal and bile duct obstruction was no longer detectable radiologically. This is the first report of an exclusively laparoscopic management of IBS.

Gallstone disease in children

Gallstone disease in children is evolving, and for the previous 3 decades, the frequency for surgery has increased greatly. This is in part because of improved diagnostic modalities, but also changing pathology, an increased awareness of emerging comorbidities, such as childhood obesity, and other associated risk factors. This article outlines the pathophysiology, genetics, and predisposing factors for developing gallstones and includes a review of the literature on the current and more novel medical and surgical techniques to treat this interesting disease.

Paediatric cholecystectomy: Shifting goalposts in the laparoscopic era

BACKGROUND

Laparoscopic cholecystectomy is the treatment of choice in symptomatic paediatric cholelithiasis. However, controversy exists about its role in asymptomatic cholelithiasis and biliary dyskinesia. We have reviewed the experiences of two UK paediatric centres with laparoscopic cholecystectomy over an 8.5 year period and critically evaluated the indications and outcomes of surgery.

METHODS

Patients who underwent laparoscopic cholecystectomy by a single surgeon at the Royal Aberdeen and Royal Alexandra Hospitals between May 1996 to August 2003 and September 2003 to December 2005, respectively, were studied. Information was extracted from prospectively held databases and analysed.

RESULTS

A total of 27 cholecystectomies were performed during the period of study. The mean age of patients was 11.7 years with a female preponderance. Symptomatic idiopathic cholelithiasis was the main indication for surgery (14). Cholecystectomy was also performed for haemolytic disease (3), acute recurrent pancreatitis of unknown cause (2), gallbladder trauma (1), and for asymptomatic calcific non-resolving stones (7). All patients were investigated with ultrasound scans with four patients undergoing magnetic resonance cholangiopancreatography (MRCP) for suspected common bile duct (CBD) stones. A standard four-port approach was used with the gallbladder extracted through the umbilical port. The mean operative time in the latter 13 cases was 105 minutes with a median postoperative stay of one day for the whole series. Histology revealed chronic cholecystitis in all but three cases. All patients were discharged after a six-month follow-up period.

CONCLUSIONS

The advent of laparoscopy has resulted in an expansion of the traditional indications for cholecystectomy. MRCP is a useful investigation in selected children to exclude choledocholithiasis and avoid intraoperative cholangiography. There appears to be no clear correlation between histology and presenting symptoms. The natural history of asymptomatic gallstones in children is not known although a consensus is emerging to support cholecystectomy for all calcific non-resolving gallstones.

Minilaparotomy cholecystectomy in children

AIM

Scarcity of paediatric cholelithiasis limits the obtainable experience in paediatric laparoscopic cholecystectomy (LPC). We report minilaparotomy cholecystectomy (MLC) in children which may be a useful alternative to LPC avoiding the added cost of disposable laparoscopic equipment.

METHODS

Nineteen cases underwent a retrograde MLC using a 2-4 cm transverse right upper quadrant incision. Various parameters were assessed.

RESULTS

Mean age at presentation was 10.87 years, mean length of the incision 2.8 cm, mean operative time 36.5 min, mean analgesic requirement 2 days, mean time to feed/ mobilize 1 day each, and mean duration of hospital stay was 2.7 days. All had satisfactory cosmetic result without postoperative complications.

CONCLUSIONS

MLC in children involves a small incision, excellent cosmetic scar and rapid postoperative recovery at relatively low cost. It is a good alternative to LPC.
