Elective laparoscopic cholecystectomy

Complications in pediatric laparoscopic cholecystectomy: systematic review

Laparoscopic cholecystectomy (LC) is the gold standard for surgical management in symptomatic children, but it is not without complications, bile duct injury being among the most feared. This study reviewed the complications of LC in children. MEDLINE/PubMed, CENTRAL and Lilacs were reviewed for LC. Studies in patients ≤ 18 years of age published in English, Portuguese or Spanish were selected by two independent reviewers. Data were collected for patients' characteristics, surgical information, complications, mortality and follow-up. Twenty-four papers were identified and offered 2783 patients. Mean age was 11 years (3 months-18 years). In the 93/2783 (3.3%) complications, single-port procedures were associated with seven (7.5%), 3/4-port with 81 (87.1%) and the number of ports were not specified in five. Routine cholangiography was not part of the protocol in any of the reports. Complications included wound issues (n = 24), perforation (n = 14), bleeds (n = 13), biliary tree complications (n = 9), sickle cell crisis (n = 8), fever (n = 6), leaks (n = 4), pain (n = 3), nausea/emesis (n = 3) and others (n = 9). Two of these patients had a history of obesity and cholecystitis and only two biliary tree lesions were diagnosed intra-operatively. Seventeen cases (18.3%) required re-intervention: 15 surgical and two endoscopic. Issues related to biliary tree included: common bile duct lesion (n = 6), biliary fistula (n = 3), clip dislocation from cystic duct (n = 1), cholangitis (n = 1) and calculus (n = 1). There was no mortality, and the mean follow-up period was 10.3 months (1 month-5 years). LC is safe in children and, although most complications are minor, almost 1/5 complications require interventions, mostly due to bleeding and biliary tree complications. Mortality has not been reported in pediatric LC.

The Inflammatory Response to Surgery in Sickle Cell Disease Patients Undergoing Cholecystectomy

Background and Objectives:

Patients with sickle cell anemia (SCA) may have elevated inflammatory markers in health, and this may be heightened after open operations. The inflammatory response of patients with SCA after minimally invasive surgeries has not been fully explored.

Patients and Methods:

Consecutive patients with SCA and with hemoglobin AA (HbAA) undergoing laparoscopic cholecystectomy for acute cholecystitis were recruited into the study. Blood samples were taken before induction of anesthesia (0-h); at 4, 12, 24, and 48 h; and on postoperative day 7. Samples were analyzed for serum C-reactive protein and interleukin (IL)-1 through IL-18.

Results:

Twenty-three patients, including 9 with SCA and 14 with HbAA, were recruited with 4 cases performed by open laparotomy. At 0-h, proinflammatory IL-1 levels (6.1 versus 4.8) and C-reactive protein levels (32.5 versus 26.6) were higher in patients with hemoglobin SS (HbSS) than in patients with HbAA, respectively. Over time, inflammatory markers were generally higher at each time-point for patients with HbSS compared with patients with HbAA for both proinflammatory and anti-inflammatory cytokines, rising immediately after surgery and up to 48 hours, then returning to baseline by postoperative day 7. There was a higher mean IL-1 level across all time-points in the HbSS group than in the HbAA group (P = .04).

Conclusion:

This exploratory study found an enhanced inflammatory response to cholecystectomy in patients with SCA compared with patients with HbAA. Minimally invasive surgical strategies for this patient group may help to mediate this response.

Laparoscopic cholecystectomy for cholelithiasis in children with sickle cell disease

Patients with sickle cell disease (SCD) suffer from an increased incidence of gallstone formation due to hemolysis of sickled red blood cells; this leads to an increased level of bilirubin in secreted bile that becomes a nidus for pigment stone formation. Laparoscopic cholecystectomy (LC) is considered a standard operative procedure for gallstone disease mainly due to lower postoperative wound complaints, faster recovery, better postoperative cosmetic results, shorter hospital stay, and earlier return to work. Although numerous studies have been published addressing both the advantages and complications of LC in acute calcular cholecystitis, there is still limited evidence concerning the safety and efficacy of LC for the management of cholelithiasis in pediatric patients with SCD, and controversies remain unresolved. In this review, we aim to comprehensively study the available literature and propose evidence-based practice recommendations for the optimal management of gallstones in pediatric SCD patients. The current practice differs greatly depending on the prevalence of SCD in a particular geographic area. We acknowledge the limited number of patients reported, the lack of randomized control trials addressing the practice of specific recommendations, and the need for further evidence-based studies.

Cholecystectomy in sickle cell disease patients: is there more acute chest syndrome after laparoscopy? A case controlled study

Laparoscopy is increasingly being recommended in order to reduce postoperative complications among sickle cell disease patients undergoing cholecystectomy. Acute chest syndrome is the most deadly of these complications. The purpose of this study was to assess if laparoscopic approach reduces postoperative complications related to sickle cell disease after cholecystectomy. A retrospective study of records of sickle cell patients who underwent cholecystectomy for cholelithiasis, from January 1990 to December 2005 was conducted. 136 sickle cell patients underwent surgery: 47 (34.5%) by laparoscopy and 89 (63.5%) by laparotomy. The mean operative time was 71.4+/-18.9 min in the laparoscopy group and 61.2+/-15.3 min in the laparotomy group (non-significant difference). The mortality was not significantly different between the two groups: one patient died in the open cholecystectomy group but no death occurred in the laparoscopic one. The morbidity related to the sickle cell disease was significantly higher in the laparoscopy group [n=5 (10.5%)] than in the laparotomy group [n=4 (4.5%)] (p=0.04). This difference was associated with a higher rate of acute chest syndrome in the laparoscopy group [n=4 (8, 5%)] compared to that in the laparotomy group [n=1 (1.1%)] (p=0.01). There were more complications related to sickle cell disease in the laparoscopy group due to acute chest syndrome. Thus, these data should be confirmed in further randomized studies which must be undertaken.

Colelitíase no paciente pediátrico portador de doença falciforme

OBJETIVO: Considerando a alta freqüência da colelitíase no paciente pediátrico com doença falciforme e a controvérsia na literatura sobre a abordagem da condição, o presente texto objetiva revisar a literatura disponível. FONTE DE DADOS: Revisão dos estudos sobre colelitíase no paciente falciforme, publicados no período entre 1980 e 2007, em língua inglesa e portuguesa, envolvendo pacientes na faixa etária de zero a 18 anos e utilizando os bancos de dados Medline e Lilacs. SÍNTESE DOS DADOS: A colelitíase é a complicação digestiva mais comum no paciente falciforme e sua incidência aumenta com a faixa etária. Os mecanismos fisiopatológicos são conhecidos, assim como os métodos diagnósticos. A conduta terapêutica consensual na colelitíase sintomática é a colecistectomia, preferencialmente por via laparoscópica. Nos casos assintomáticos, a maioria dos autores recomenda a conduta cirúrgica, para evitar complicações, confusão no diagnóstico diferencial de dor abdominal futura e menor risco cirúrgico. Contudo, não existe consenso na literatura, havendo base para a adoção de conduta expectante. CONCLUSÕES: A doença falciforme tem grandes variações em sua apresentação clinica, história natural e gravidade da hemólise. Algumas populações podem apresentar menor freqüência de colelitíase e menor número de pacientes sintomáticos, possivelmente em razão de variações de haplótipos, fatores ambientais e diferentes manejos clínicos. Ainda não existem dados suficientes na literatura ou estudos randomizados e controlados que possibilitem definir o momento ideal para a colecistectomia no paciente falciforme com litíase assintomática. Dessa maneira, dependendo de características individuais e da população, podem ser aceitos o seguimento clínico ou a indicação precoce de colecistectomia.

Tolerance of laparoscopy and thoracoscopy in neonates

OBJECTIVES

Video-surgery in neonates is recent. Data on the respiratory, hemodynamic, and thermic effects during the first month of life are still sparse. This study aimed to evaluate the tolerance of video-surgery in neonates and to determine the risk factors of per-operative complications.

METHODS

From 1994 to 2004, 49 neonates (mean age: 11 days; weight: 3285 g) underwent 50 video-surgical procedures. Indications for laparoscopy were duodenal atresias, volvulus with malrotation, pyloric stenosis, gastroesophageal reflux, cystic lymphangiomas, ovarian cysts, biliary atresia, and congenital diaphragmatic hernias; indications for thoracoscopy were esophageal atresias and tracheoesophageal fistula.

RESULTS

Median operative time was 79 minutes. Mean insufflation pressure was 6.7 mm Hg (range: 3-13). Oxygen saturation decreased, especially with thoracic insufflation or high-pressure pneumoperitoneum. Systolic arterial pressure, which decreased in 20% of the patients, was controlled easily with vascular expansion. Thermic loss (mean postoperative temperature: 35.6 degrees C) was proportional to the duration of insufflation. No surgical incident was noted. Ten anesthetic incidents occurred (20%), 3 of which required temporary or definitive interruption of insufflation (O2 saturation <70%). Risk factors for an incident were low preoperative temperature, high variation of end-tidal pressure of CO2, surgical time >100 minutes, thoracic insufflation, and a high oxygen or vascular expansion requirement at the beginning of insufflation.

CONCLUSION

The neonate's high sensitivity to insufflation is an important limiting factor of video-surgery. The described profile of the neonate at risk may help to reduce the frequency of adverse effects of this technique and improve its tolerance.

Laparoscopic approach as primary treatment of common bile duct stones in children

BACKGROUND

Preoperative endoscopic retrograde cholangiopancreatography and endoscopic sphincterotomy (ES) are an effective strategy for choledocholithiasis, but complications such as pancreatitis and outcome in children are unknown. The laparoscopic cholecystectomy became the new gold standard in children for cholelithiasis. For the choledocholithiasis in children, the attitude is more controversial. We analyzed our series of laparoscopic approach for the management of choledocholithiasis in children to determine if it is an effective procedure.

PATIENTS AND METHOD

Between 1996 and 2001, 126 children were treated for cholelithiasis in our institution; 13 children (10.3%) were managed for a choledocholithiasis. We reviewed age at symptom onset results of paraclinical examinations, the type of laparoscopic management, and postoperative outcome.

RESULTS

The mean age at clinical signs was 9.9 years (range, 3 months-15.5 years). One child was excluded because he had a preoperative ES. Twelve children had a laparoscopic cholecystectomy and cholangiogram at the same time. A choledocholithiasis was found in 10 cases. A flush of the common bile duct (CBD) was performed in all cases with a 3F or 5F ureteral catheter; the stone was pushed into the duodenum in 3 cases and successfully extracted in 3 with a 4F Dormia or Fogarty catheter. One child needed a conversion to open surgery. Three times, an ES was necessary in postoperative course in each case for clinical and biologic signs of CBD obstruction or pancreatitis (30%). All children are symptom-free with an average follow-up of 28 months.

CONCLUSION

Laparoscopic CBD exploration for choledocholithiasis can be performed safely in children at the time of cholecystectomy and can clear all of the stones in the CBD in two thirds of cases. If there is residual obstruction, a postoperative ES can be performed. We suggest primary treatment of choledocholithiasis by laparoscopic approach in children.

[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.

[Biliary lithiasis in childhood: therapeutic approaches]

Until recently, biliary lithiasis was considered infrequent in childhood. According to their composition, gallstones can be classified into cholesterol stones and pigment stones. The latter are mainly composed of calcium salts of unconjugated bilirubin and are divided into hard black and soft brown stones. In children, up to 75 % of gallstones are pigment stones. Their etiology is often unknown. Biliary lithiasis in children differs from that in adults and there is very little scientific evidence on the most suitable therapeutic procedures. Symptom-free stones usually have a benign course and do not require medical or surgical treatment. Symptoms are often nonspecific and include dyspepsia and chronic abdominal pain. These symptoms are an indication for ultrasonographic scan to rule out the presence of gallstones. Cholecystectomy is the definitive treatment for gallstones but is not always indicated. Medical treatment with ursodeoxycholic acid is indicated in oligosymptomatic and asymptomatic lithiasis with transparent, soft, cholesterol-rich stones and a functional bladder and in patients with a high surgical risk.

Pediatric laparoscopic splenectomy: benefits of the anterior approach

INTRODUCTION

Splenectomy is frequently performed in children for various hematologic and autoimmune disorders. We reviewed our indication for splenectomy, our technique of laparoscopic, splenectomy, and our results. The aim of this study was to show if an anterior approach with elective vessel endoligature in a patient in decubitus position was a better and safer approach than the other techniques previously published.

PATIENTS AND METHODS

Between January 1996 and December 2002, 54 children underwent laparoscopic splenectomy. We use the anterior pedicle approach and elective vessel endoligature in order to prevent persistence of any exogenous material. Sixteen children also had a concomitant cholecystectomy. Their age ranged between 1 and 18 years (mean 7.5 years). Twenty children had hereditary spherocytosis, 15 were affected by sickle cell disease, six had an idiopathic thrombocytopenia, four had beta-thalassemia, and nine another hemolytic disease.

RESULTS

Mean operative time was 150 min (range, 115-230 min). Hospital stays ranged from 3 to 15 days (mean: 5.4). Seven patients had complications (four pneumonia and three deep abscess with successful antibiotic treatment). Median follow-up was 42 months (2 months-6 years) without problems regarding procedure.

DISCUSSION

With this technique consisting in first elective arterial and secondary venal ligature, we preserved blood splenic sequestration and pancreatic tail lesion. The procedure is safer. For us, considering the low complication rate for this type of patient, and the advantages of a small abdominal trauma in the postoperative period, laparoscopy with anterior approach for elective splenectomy and eventual cholecystectomy in hematologic disorders is the best technique.
