Patterns of care and burden of chronic idiopathic thrombocytopenic purpura in Brazil

AIMS

Although several therapeutic options are available for chronic immune thrombocytopenic purpura (cITP), little is known about the treatment of cITP in Brazil.

MATERIALS AND METHODS

A multi-center, retrospective chart review, observational study was designed to describe the treatment patterns, clinical burden, resources use, and associated costs for adult patients diagnosed with cITP and treated in public and private institutions in Brazil. Patient charts were screened in reverse chronological order based on their last visit post January 1, 2012. (All costs were calculated using 1.00 USD = 3.9571 BRL, from February 2016.) Results: Of 340 patient charts screened, 50 patients were eligible for inclusion in the study. Single-drug therapy (prednisone, dexamethasone, or dapsone) was the most commonly used treatment, followed by combination therapies (azathioprine + prednisone, azathioprine + prednisone + danazol, and prednisone + dapsone). Splenectomy was performed in 22% of patients after at least first-line treatment. Platelet count and number of bleeding episodes at diagnosis were 31,561.1/mm³ (SD = ±26,396.1) and 40 episodes, respectively; in first-line, 92,631.1/mm³ (SD = ±79,955.3) and 19 episodes, respectively; in second-line, 96,950.0/mm³ (SD = ±76,476.4) and 17 episodes, respectively. Private system patients had a higher median cost compared to public system patients (USD 17.49/month, range = 0-2,020.77 vs USD 9.51/month, range = 0-192.64, respectively).

LIMITATIONS

This study does not allow conclusions for causal explanations due to the cohort study design, and treatment patterns represent only the practices of physicians who have agreed to participate in the study.

CONCLUSIONS

The data indicate that available therapeutic strategies for second- and third-line therapies appear to be limited.

[Advanced schistosomiasis chemotherapy and assistance in Xinjian County, 2005-2009]

OBJECTIVE

To understand the status of chemotherapy and assistance for advanced schistosomiasis patients in Xinjian County, 2005-2009.

METHODS

The data of chemotherapy and assistance for patients with advanced schistosomiasis in Xinjian County from 2005 to 2009 were collected and analyzed statistically by using The Information Management System for Advanced Schistosomiasis Chemotherapy and Assistance in Jiangxi Province.

RESULTS

Among 636 cases, the sex ratio of male to female was 1.19: 1, and the average age was 61.52 +/- 11.2 years old. Ascites was the main symptoms of patients (93.71%), and the percentage of splenectomized ones was 32.38% among them. The IHA-positive rate, HBsAg-positive rate and repeat treatment rate were 31.6%, 24.37% and 44.50%, respectively. The clinical cure rate, recovery rate and death rate were 43.53%, 55.94% and 5.97%, respectively.

CONCLUSION

The advanced schistosomiasis chemotherapy and assistance improves the symptoms and life quality of these patients.

Outpatient laparoscopic surgery: feasibility and consequences for education and health care costs

BACKGROUND

The purpose of this paper is to describe the outcome of ambulatory laparoscopic cholecystectomy (LC), antireflux surgery, adrenalectomy and splenectomy and possible implications for surgical education and health care costs.

METHODS

Prospective, observational study 1994-2003.

RESULTS

The success rate of ambulatory treatment was 83.5% in 1060 LC patients, 80% in 113 antireflux procedures, 100% in 22 laparoscopic adrenalectomies, and 75% in 12 laparoscopic splenectomies. In a total number of 1207 patients, health care costs were reduced by almost 700,000 dollars, compared to 1-day hospital stay. The educational potential of same-day surgery is large, due to high numbers of patients, and 80% of our educational potential has been exploited.

CONCLUSION

Ambulatory laparoscopic surgery is cost effective, patient friendly, and appropriate for surgical resident training. Strict organization of security rules is mandatory.

Open versus laparoscopic splenectomy for idiopathic thrombocytopenic purpura: clinical and economic analysis

BACKGROUND

Since 1991, laparoscopic splenectomy (LS) has gained acceptance in the treatment of hematologic disorders, including idiopathic thrombocytopenic purpura (ITP). Several studies suggest that LS provides benefits over open splenectomy (OS). However, study design flaws hinder formal technology assessment.

METHODS

We retrospectively reviewed medical and administrative records of patients who underwent splenectomy for ITP between January 1995 and December 2000 to compare clinical and economic outcomes associated with LS and OS.

RESULTS

Eighty-six patients were identified; 42 underwent an attempted LS and 44 had OS. Preoperative patient characteristics were similar between groups. Mean operative and anesthesia times for LS and OS were 167 and 201 minutes and 119 and 151 minutes, respectively (P <.001). Overall transfusion and postoperative complication rates were similar between groups. On average, LS patients required 1.2 fewer days of parenteral analgesia and were able to tolerate a general diet 1.7 days earlier. Mean postoperative stay was 2 days lower for LS patients and mean total direct costs did not differ by surgical method (US dollars 8134 vs US dollars 8200).

CONCLUSIONS

This observational study shows that LS is safe and offers advantages over OS: less postoperative pain, earlier general diet tolerance, and shorter hospital stay. These benefits are obtained at no significant additional cost.

Current concepts in minimal access surgery for children

Since the introduction of minimal access surgery to general surgeons in the 1980s, pediatric surgeons have been employing this innovative technology to perform surgery on children. Video technology and miniaturized instruments have brought the laboratory to the operating room; in many cases several small incisions are the only access necessary to perform complicated procedures that would otherwise require a large wound. Additional benefits of minimal access surgery may include reduced postoperative analgesic requirements, shortened length of stay, and faster resumption of normal activities. Increased operative costs offset some of these gains. The pediatric surgical community has embraced minimal access techniques for some operations; others remain controversial.

Laparoscopic adrenalectomy and splenectomy are safe and reduce hospital stay and charges

The proposed benefits of laparoscopy for certain surgical procedures have been decreased post-operative pain and hospital stay balanced against the proposed deficits of increased costs. We have reviewed our data to evaluate factors associated with patient, procedure, and hospital charges for patients undergoing open versus laparoscopic adrenalectomy and splenectomy during the same time period. Eighty-seven patients underwent adrenalectomy (n = 47) or splenectomy (n = 40) from October 30, 1995 to June 6, 2001 and were retrospectively reviewed. Patient and operative factors were analyzed by intent to treat; the major endpoints were operating room (OR) time in minutes, blood loss in cm3, length of hospital stay in days, and charges broken down by anesthesia/operation [OR/recovery room (RR)] and total charges in dollars x 1000. Comparisons of means were analyzed by unpaired t test; data are presented as mean +/- SEM, and significance is defined as P < 0.05. Median age of the group was 47 years (range 20-77). Forty-five patients underwent a laparoscopic approach of which two were converted to open (4%) as compared with 42 undergoing an open operation; one patient from each group was excluded from outcome analyses because of prolonged hospitalization (>3 weeks). Operative mortality of the whole group was one per cent. There were no differences between the groups with respect to age, gender, or comorbidity. The laparoscopic group had significantly longer operative times and OR/RR charges. However, the length of hospital stay and the total charges for the patient undergoing a laparoscopic approach were significantly less (P < 0.05). We conclude that a laparoscopic approach for adrenalectomy or splenectomy can be accomplished in approximately 95 per cent of patients selected for this procedure. Despite prolonged OR time and increased OR/RR charges the laparoscopic procedures resulted in significantly decreased length of hospital stay and overall patient charges. Laparoscopy is a safe and cost-effective approach and should be strongly considered in patients requiring adrenalectomy or splenectomy.

Use of laparoscopic splenectomy in developing countries: analysis of cost and strategies for reducing cost

BACKGROUND

In general, laparoscopic surgery is more expensive than open surgery. However, recent reports showed lower overall cost.

PATIENT AND METHODS

Fourteen patients underwent laparoscopic splenectomy (LS) and 15 patients open splenectomy (OS). Patients were evaluated with regard to blood loss, complication rate, length of hospital stay, operative time, presence of accessory spleens, hospital cost, and total cost. For the OS group, there was no laparoscopic instrument cost, and the total cost was equal to the hospital cost. In the LS group, total cost was calculated by adding the hospital cost to the cost of laparoscopic instruments.

RESULTS

The postoperative hospitalization was shorter in the LS group than the OS group (3.4 vs. 7.5 days), but the operating time was significantly longer for the LS group. The mean hospital cost was calculated as US $1,055 in the LS group and $1,664 in the OS group. The overall total cost was $1,664 for the OS group and $2,064 for the LS group. In the LS group, less morbidity and shorter postoperative hospital stay resulted in lower hospital cost.

CONCLUSION

The cost for laparoscopic instruments is the main factor responsible for the high total cost of LS. Resterilization of disposable laparoscopic instruments is feasible and a more economic way of treatment compared with splenectomy with totally disposable laparoscopic instruments and has costs comparable to those of open surgery.

Pharmacoeconomics of therapy for ITP: steroids, i.v.Ig, anti-D, and splenectomy

Factors that influence the choice of therapeutic option in treating idiopathic thrombocytopenic purpura (ITP) include cost, toxicity, and efficacy of the agent. Today the most commonly used agents for treating ITP include glucocorticoids, intravenous immunoglobulin (i.v.Ig), anti-D, and splenectomy. Splenectomy cannot be avoided in some instances, but i.v.Ig, and anti-D offer viable treatment alternatives in many cases. i.v.Ig and anti-D are both equally efficacious; however, anti-D therapy may come with lower cost to the patient and the healthcare system. Thus, in treating patients with ITP, clinical and economic considerations should be considered when choosing among the various treatment options.

Laparoscopic versus open splenectomy in the pediatric population: a contemporary single-center experience

The purpose of this study was to compare a recent contemporaneous experience between laparoscopic (LS) and open (OS) splenectomy in children. All splenectomy cases between 1994 and 1999 at our institution were reviewed. The study included open and laparoscopic cases performed according to surgeon preference. Emergency splenectomies for trauma were excluded. The patient record was reviewed for the diagnosis, indications, postoperative length of stay, operative technique, postoperative complications, blood loss/blood transfusion, total amount of parenteral narcotics, and time to resumption of oral intake. Chi-square and t tests were used to compare measured differences for statistical significance. Between May 1994 and December 1999, 52 splenectomies were performed at Vanderbilt Children's Hospital. Of these, 45 were elective operations with 29 open and 16 laparoscopic procedures. During four OS and five LS operations a concomitant cholecystectomy was performed. The median patient age was 9.2 years (range 0.5 to 17.3). There was no statistical difference between the two groups in terms of age, weight, American Society of Anesthesiologists class, or estimated blood loss. There were no immediate postoperative complications in either group. There were no conversions from LS to OS. The mean duration of surgery was 264 minutes (LS) versus 169 minutes (OS) (P < 0.05). The average time to first oral intake was shorter in patients undergoing LS (1.1 vs 1.6 days, P < 0.05) and the mean postoperative length of stay was also shorter in the LS group (1.3 vs 3.1 days, P < 0.05). The use of postoperative intravenous narcotics (in morphine-equivalent doses) was significantly less in LS patients than in OS patients (7.5 mg or 0.15 mg/kg vs 46.9 mg or 1.5 mg/kg, P < 0.001), as was the need for PCA pump analgesia (90% in the OS group vs 25% in LS group, P < 0.01). Overall the average hospital charge (anesthesia fee, narcotics charge, and hospital room charge) was $5400 (range $4240-6250) in the OS group and $4950 (range $4450-6240) in the LS group (P < 0.05). Among the nine patients undergoing splenectomy with cholecystectomy, findings between the OS and LS groups were similar except for one late complication consisting of a diaphragmatic hernia in an LS patient. Both LS and OS with or without a concomitant procedure can be accomplished safely in children. LS appears to result in longer operative times but shorter lengths of stay, earlier first oral intake, and significantly fewer requirements for intravenous narcotics; all of these contribute to a reduction in hospital charges compared with the open operation.

Laparoscopic splenectomy in chronic idiopathic thrombocytopenic purpura

Splenectomy remains the definitive treatment for idiopathic thrombocytopenic purpura (ITP). Issues related to timing of splenectomy, perioperative management of platelet count, deep vein thrombosis prophylaxis, and preoperative vaccination are not standardized. Predicting the outcome of splenectomy is desirable but, again, consistent evidence for a particular approach is lacking. Laparoscopic splenectomy, first introduced in 1991, has removed some of the barriers to acceptance of splenectomy and may well change its place in the various treatment algorithms. This article reviews current knowledge with respect to laparoscopic splenectomy and provides an analysis of current evidence regarding issues of safety, efficacy, and cost effectiveness. Surgical technique is briefly reviewed. The information is drawn from a comprehensive analysis of the literature, as well as my own large experience with laparoscopic splenectomy, the majority of which has been focused on laparoscopic splenectomy for ITP.

The potential for treatment of idiopathic thrombocytopenic purpura with anti-D to prevent splenectomy: a predictive cost analysis

Idiopathic thrombocytopenic purpura (ITP) is an autoimmune disorder affecting both children and adults that can be manifested by severe bleeding episodes. Adult ITP patients have a low rate of spontaneous remission, and symptomatic patients commonly undergo splenectomy; however, maintenance therapy may increase the rate of remission, allowing splenectomy to be avoided. Anti-D is a recently licensed treatment for ITP that has the potential to delay, and possibly avoid, the need for splenectomy. We used preliminary data from an ongoing clinical trial to evaluate the costs involved in using anti-D therapy for 1 year with the intent of avoiding the need for splenectomy. We accounted for different possible outcomes at the completion of the clinical trial. An economic model with a theoretical cohort of 100 patients was developed using the model of an ongoing clinical trial. The average wholesale price was used to determine the cost of an infusion of anti-D based on an average dose ($1,213 per infusion). The cost of splenectomy was determined by a literature review ($16,000). Costs were calculated for all known patient outcomes; where outcomes were unknown and likely to vary, all possible outcomes were accounted for (splenectomy or no splenectomy). In our theoretical cohort, 31 of 100 patients were taken off anti-D and received splenectomy, 32 of 100 were stable after receiving anti-D and would not need splenectomy, and 37 of 100 had Indeterminate outcomes after receiving anti-D. When compared with the cost of the hypothetical scenario of initially giving all 100 patients splenectomy ($1.6 million), a minimum of 47 patients would have to avoid splenectomy to result in a cost savings for our cohort of 100 patients. The group of 47 patients avoiding splenectomy would be composed of the 32 patients comprising the stable group and at least 15 of the 37 patients comprising the group with indeterminate outcomes. If all 37 of the patients in the group with indeterminate outcomes avoid splenectomy, $363,000 and 69 spleens would be saved. Our data suggest that in the phase III trial of maintenance anti-D therapy versus immediate splenectomy, anti-D therapy will be a cost-effective option if 47% or more of patients avoid splenectomy.

Cost-effectiveness of laparoscopy in children

BACKGROUND

Laparoscopy may offer fast recovery and improved cosmesis, but its cost has been perceived as excessive.

OBJECTIVE

To analyze the total hospital costs of laparoscopy vs open surgery.

DESIGN

Retrospective cost-effectiveness analysis evaluating all cases performed in a 36-month period (September 1995 to August 1998). Cases were evaluated for operative time, itemized cost of supplies, and length of hospitalization.

SETTING

Operations performed by pediatric surgeons in a tertiary care children's hospital.

PATIENTS

Consecutive children undergoing laparoscopic or open appendectomies, cholecystectomies, fundoplications, and splenectomies. Patients were not randomized to laparoscopy, or open surgery.

INTERVENTIONS

Laparoscopic procedures performed with a core set of reusable equipment and a limited number of disposable instruments.

MAIN OUTCOME MEASURES

Cost surplus of laparoscopy was evaluated, and compared with savings associated with decreased hospital stay, to obtain cost-effectiveness of laparoscopy per procedure.

RESULTS

There were 26 laparoscopic and 359 open appendectomies; 33 laparoscopic and 3 open cholecystectomies; 16 laparoscopic and 18 open fundoplications; and 16 laparoscopic and 7 open splenectomies. Excess operating costs per procedure were $442.00 for appendectomy, $634.60 for fundoplication, $847.50 for cholecystectomy, and $1551.30 for splenectomy. Hospital stay was decreased for all laparoscopies, resulting in an overall savings per laparoscopic procedure of $2369.90 for appendectomy, $5390.90 for fundoplication, $1161.00 for cholecystectomy, and $858.90 for splenectomy.

CONCLUSIONS

Laparoscopy is cost-effective, particularly for fundoplication, appendectomy, and cholecystectomy. Detailing the costs of supplies, operating time, and length of stay allows interinstitutional comparison and critical cost-analysis of laparoscopy. With a more selective use of reusable instruments and further shortening of operative time, the global savings of laparoscopy may increase.

A case controlled comparison of open and laparoscopic splenectomy in children

BACKGROUND

This case controlled study compares the efficacy, safety, and cost of laparoscopic splenectomy (LS) and open splenectomy (OS) for hematologic disorders in children.

METHODS

The records of 82 consecutive children and adolescents undergoing splenectomy for hematologic disorders between August 1994 and September 1997 were reviewed retrospectively.

RESULTS

Fifty patients underwent LS by a lateral approach and 32 underwent OS through a left subcostal incision. Mean age was 7.76 years for LS and 6.9 years for OS. Patient weights were similar: (LS, mean 30.5 kg; OS, mean 27.6 kg). Hematologic indications included hereditary spherocytosis in 43 children (LS 26, OS 17), sickle cell anemia with sequestration in 13 (LS 7, OS 6), immune thrombocytopenic purpura in 14 (LS 8, OS 6), and 12 with other disorders (LS 9, OS 3). Concomitant cholecystectomy was performed in 10 of 50 LS and 6 of 32 OS cases. Accessory spleens were identified in 8 of 32 (25%) OS and 9 of 50 (18%) LS cases (P = .578). No LS procedures required conversion to OS. The mean estimated blood loss was 54.4 mL for LS and 49.0 mL for OS (P = .233). LS required a longer operative time (115 vs 83 minutes, P = .002), less need for postoperative intravenous narcotic (51% vs 100%, P < .0001), lower total narcotic doses (0.239 vs 0.480 mg/kg morphine, P = .006), shorter length of hospital stay (1.4 +/- 0.97 vs 2.5 +/- 1.43 days, P = .0001), and lower average total hospital charges ($5713 vs $6564) than OS. There were no deaths or major complications in either group.

CONCLUSIONS

Laparoscopic splenectomy is a safe and effective procedure in children with hematologic disorders resulting in longer operative times, less narcotic administration, shorter length of stay, and lower total hospital charge.

Laparoscopy improves outcomes for pediatric splenectomy

BACKGROUND

Pediatric laparoscopic splenectomy is a relatively new surgical procedure with a limited number of reports comparing its outcomes to that of the open procedure. The authors have minimized the invasiveness of our procedure by using only three ports and have described the technique as well as compared it with the open method.

METHODS

A retrospective review of seven laparoscopic splenectomies (LS) using a three port technique were compared with seven open splenectomies (OS) performed for similar indications at a single children's hospital.

RESULTS

The average age in the LS group was 8.7 years compared with 8.9 years for OS, (P value not significant), and the average weights were also similar. The indications for splenectomy were hereditary spherocytosis, idiopathic thrombocytopenic purpura, sickle cell anemia, and splenic cyst. All splenectomies were performed safely with an average estimated blood loss of 41 mL for LS and 34 mL for OS (P value not significant). Operative time averaged 147 minutes for LS and 86 minutes for OS (P < .05). LS patients recovered more rapidly and were discharged home on a median of postoperative day (POD) 2 versus POD 4 for OS (P < .05). LS patients received significantly less total amount of intravenous pain medication with an average of 0.18 mg/kg of morphine sulfate versus 0.8 mg/kg for OS (P< .05). Total hospital charges were higher for LS with an average of $10,899 versus $8,275 for OS (P < .05).

CONCLUSIONS

Laparoscopic splenectomy currently is a safe procedure, offering better cosmesis, much less pain, and a shorter hospital stay compared with the traditional open procedure. The more sophisticated equipment and time needed to carry out the procedure led to a modestly increased hospital cost.

[Gastrectomy with radical D2 lymph node excision--effective and economically standardized therapy of adenocarcinoma of the stomach]

In a retrospective single center study, the impact of radical D2-lymph adenectomy and splenectomy on operativ course, morbidity, mortality and long-term survival, in 243 patients who underwent radical surgical therapy for gastric cancer, was analyzed. D2-lymph node dissection during gastrectomy or gastric resection did not influence blood loss, artificial respiration time, ICU days or surgical morbidity, whereas splenectomy correlated with a higher hospital mortality, leakage and abscess rate. Due to routinely performed D2-lymphadenectomy long term survival rate (5 years) was 40.6% for all (in detail: 96% in stage IA; 68.5%/IB; 61.2%/II; 35.8%/IIIA; 17.3%IIIB; and 2.6% in stage IV and 58.1% for curative resected patients.

Laparoscopic splenectomy: reduction of hospital charges

Laparoscopic splenectomy has become our procedure of choice for the surgical management of immune thrombocytopenic purpura. Hospital charges for this procedure were analyzed for 24 consecutive patients undergoing laparoscopic splenectomy. Total charges have decreased over time and average a $233 decrease per patient treated. The decreased charges are related to decreased operating room charges. Furthermore, charges are shown to be related to the length of postoperative stay. Choice of instrumentation has kept intraoperative charges for disposables stable.

Cognitive trauma care is undervalued: adult splenic injury as a paradigm

Nonoperative management (NOM) of adult splenic injury is evolving. Economic aspects of NOM have not been examined. We hypothesize that NOM reduces hospital and professional charges. Surgeon, radiologist, and hospital charges and reimbursements, and clinical outcome were obtained for 77 consecutive adult splenic injury patients (> or = 15 years old) over a 3-year period. NOM succeeded in 30 of 31 patients. NOM was associated with lower surgeon fee ($1,148 vs $4,452; P < 0.0001), surgeon reimbursement ($587 vs $2,773; P = 0.0001), and hospital charge ($18,982 vs $48,790; P = 0.001) relative to operative management. Radiologist fee ($1,776 vs $2,285) and reimbursement ($1,069 vs $1,537) were not significantly affected. No significant difference existed between surgeon (primary care provider) and radiologist reimbursement for NOM. ISS poorly correlated with economic variables. We conclude that cost reductions are another potential advantage of NOM. Surgeon reimbursement for the cognitive skills involved in NOM is minimal. Future health finance policy should recognize the cognitive aspects of trauma care.

Is pediatric laparoscopic splenectomy safe and cost-effective?

OBJECTIVE

To determine whether laparoscopic splenectomy (LS) is a safe, cost-effective alternative to open splenectomy (OS).

DESIGN

Retrospective comparison and economic evaluation.

SETTING

Tertiary care children's hospital.

PATIENTS

Children with hematologic disease involving the spleen.

INTERVENTIONS

Laparoscopic splenectomy (10 patients); OS (10 patients).

MAIN OUTCOME MEASURES

Safety of LS and cost differential between LS and OS.

RESULTS

Operative time was longer for LS. Discharge occurred 64 hours postoperatively for LS and 79 hours for OS (P < .03). Patients who underwent LS returned to activity 1 to 5 weeks faster than patients who underwent OS. The average (+/-SD) operative charges for LS was $7176 +/- $2064 and for OS, $1977 +/- $344 (P < .001). Total hospital charges averaged $13,033 +/- $2976 for LS and $7106 +/- $1923 for OS (P < .001).

CONCLUSIONS

Laparoscopic splenectomy can be performed safely in children. In our hospital, LS is more expensive than OS. The faster return to school and normal activity warrants the continued use of this procedure despite the increased cost.

Comparison of laparoscopic and open splenectomy in children with hematologic disorders

OBJECTIVE

To compare laparoscopic and traditional open splenectomy in children with nonmalignant hematologic disorders.

STUDY DESIGN

Retrospective review of 36 consecutive nonrandomized splenectomies (16 laparoscopic and 20 open) performed for hematologic disorders at a single pediatric institution during the past 3 years. The two-sided Mann-Whitney U test for non-parametric variables was used for statistical analysis.

RESULTS

An open procedure was performed on 20 patients (mean age, 9.7 years), five of whom had a concomitant cholecystectomy. A laparoscopic splenectomy was performed on 16 children (mean age, 10.3 years), seven of whom had a concomitant cholecystectomy. The mean anesthesia and operative times were longer in the laparoscopic than in the open group (p < 0.001). However, the mean number of hours of postoperative analgesia was less in the laparoscopic group (p < 0.005). Patients who had laparoscopic splenectomy were also discharged home earlier (p < 0.01) and resumed a regular diet sooner. Mean operating room charges were higher in the laparoscopic group (p < 0.001), but total hospitalization costs were not significantly different. Postoperative complication rates were similar. The hematologic response was comparable.

CONCLUSIONS

laparoscopic splenectomy is feasible and safe in children with hematologic disorders. Although it currently requires more operative time than the open approach, it is superior with regard to duration of postoperative analgesia, duration of hospital stay, and recovery of bowel function.

A case-controlled study of laparoscopic splenectomy

BACKGROUND

The utility of laparoscopic splenectomy (LS) has not been tested in general surgical practice. This is a case controlled study comparing the clinical results and economics of L.S. and open splenectomy (OS) in a community hospital.

METHODS

The outcome of a series of 15 patients undergoing LS were compared to 15 patients undergoing OS matched for diagnosis, splenic weight, age, and main co-morbidites, selected by a person independent of the project.

RESULTS

In both series, the indications were immune thrombocytopenic purpura, hemolytic anemias, hairy cell leukemia and, staging for Hodgkin's disease. LS resulted in shorter hospitalization (2.3 vs 8.8 days) with fewer postoperative complications. However, the operation was 1.7 times as long, and the operating room charge 2.9 times as high, so that the total cost of LS ($18,015) was greater than that for OS ($14,524). If the cost of treatment of complications is included, then the total is the same for both at our institutions.

CONCLUSION

Except for a few indications not addressed in this study, LS can be used in lieu of OS.

Laparoscopic versus open splenectomy for immune thrombocytopenic purpura

BACKGROUND

We sought to determine whether laparoscopic techniques can reduce the operative morbidity of surgery in patients undergoing splenectomy for immune thrombocytopenic purpura (ITP).

METHODS

All patients (60) undergoing splenectomy for ITP at the Royal Adelaide Hospital from January 1985 to November 1995 were reviewed. Results of patients undergoing open operation were obtained by means of retrospective case note review, whereas details of all patients undergoing laparoscopic splenectomy were collected prospectively and maintained on a computerized database.

RESULTS

Forty-seven patients underwent splenectomy with an open technique and 13 with a laparoscopic technique. Patient groups were demographically similar. All laparoscopic procedures were completed with the laparoscopic technique. An accessory spleen was also removed at laparoscopic operation from two (15%) patients and at open operation from three patients (6%). Two more accessory spleens were missed at the original procedure, one at open operation and one at laparoscopic operation. These required later removal by using open and laparoscopic techniques, respectively. Blood and platelet transfusion requirements were reduced by the laparoscopic approach. Although mean operating times were similar (87 versus 88 minutes), laparoscopic splenectomy was associated with a greatly reduced postoperative hospital stay (10 versus 2 days, median; p < 0.0001) and no major morbidity. Long-term normalization of platelet counts was similar for the two techniques. The laparoscopic approach resulted in a reduction in hospital treatment costs from $4224 to $2238 per case (cost savings of $1986 per case).

CONCLUSIONS

Laparoscopic splenectomy results in improved clinical outcomes and reduced costs for patients undergoing elective splenectomy for ITP.

Laparoscopic splenectomy by the lateral approach: a safe and effective alternative to open splenectomy for hematologic diseases

BACKGROUND

The purpose of this study was to compare the clinical outcomes and expense of laparoscopic splenectomy by the lateral approach with open splenectomy for the treatment of hematologic diseases.

METHODS

Medical records of 20 matched patients undergoing open splenectomy and lateral approach laparoscopic splenectomy were retrospectively reviewed detailing perioperative course, clinical outcome, and hospital charges.

RESULTS

Patients undergoing laparoscopic splenectomy (n = 10) experienced longer anesthesia (324 versus 176 minutes; p < 0.05) and operative times (261 versus 131 minutes; p < 0.05) than those undergoing open splenectomy (n = 10). No difference was noted in both intraoperative and postoperative packed red blood cells transfused. Laparoscopic splenectomy resulted in a shorter duration of nasogastric decompression (1.2 versus 2.6 days), more rapid resumption of normal oral intake (1.9 versus 4.4 days), and earlier hospital dismissal (3.0 versus 5.8 days). Although hospital charges were not significantly higher in the laparoscopic group ($17,071.00 versus $13,196.00; p > 0.05), operative charges were always significantly higher.

CONCLUSIONS

When compared with open splenectomy, lateral approach laparoscopic splenectomy allows a more rapid return of normal gastrointestinal function and shorter hospital stay. The operative expense of laparoscopic splenectomy is significantly higher; however, the overall hospital expense is not. If costs can be decreased, the lateral approach laparoscopic splenectomy will be the preferred operative approach.

Laparoscopic splenectomy for idiopathic thrombocytopenic purpura: comparison of laparoscopic surgery and conventional open surgery

In chronic idiopathic thrombocytopenic purpura (ITP), the two main therapeutic choices are steroid treatment or splenectomy. The adult form of ITP is described as a disease found primarily in young adults, with a female predominance. Treatment with steroids effects a complete response in less than 30% of patients, whereas splenectomy is successful in more than 60% of patients who undergo it. The minimal access afforded by laparoscopic splenectomy is considered highly desirable for these patients. The purpose of this study was to compare the clinical benefits of a laparoscopic splenectomy with those of conventional open surgery for patients with ITP. From 1968 to 1993, splenectomy was performed on 51 patients: 10 operations done laparoscopically and 41 performed conventionally. Complications, postoperative pain, recovery, and hospital charges were then compared. Laparoscopic splenectomy involved minimal incisions, and a significantly lower frequency of analgesia was required for postoperative abdominal pain (1.3 vs. 3.3); hospital stay was shorter (8.2 vs. 20.1 days) (p < 0.005). Operative time was significantly longer for the laparoscopic surgery (249.2 vs. 99.8 min) (p < 0.0001), but blood loss was less (176.0 vs. 511.7 g) (p < 0.01). No intraoperative or postoperative major complications occurred with the laparoscopic procedures, compared with 46.3% with conventional surgery. Finally, the total hospital costs were lower with laparoscopic splenectomy, especially for postoperative care (p < 0.05). A laparoscopic splenectomy may well be considered the surgical treatment of choice for patients requiring a splenectomy in view of both quality of life and economy.

Laparoscopic splenectomy in childhood hematologic disorders

Laparoscopic splenectomy is a new technique that is being utilized in patients with a variety of mostly hematologic disorders. Its application in children has not been extensively documented. Between January 1994 and February 1995, 11 children less than 15 years of age underwent elective laparoscopic splenectomy. Data collected from this treatment group were compared to that from the ten most recent open splenectomy patients with comparable hematologic disorders. All procedures in both groups were successful in relief of symptoms, increase in platelet count, and/or increase in hematocrit. Operative times averaged 147 mm in the laparoscopic group, compared to 112 mm in the open group. Estimated blood loss was 32 ml in the laparoscopic group and 86 ml in the open group. Days to laparoscopic patient discharge were 3.6, compared to 5.3 days in the open group. There were no wound complications or need for perioperative platelet transfusions in the laparoscopic patients. Patient response has been uniformly positive in the laparoscopic group. Reusable access trocars are utilized for two of the four working ports. Stapling devices and special tissue morselizers are not required. There are no additional operating room or surgeons fees incurred in the laparoscopic procedures. This series demonstrates that laparoscopic splenectomy is a safe, cost-efficient alternative to open splenectomy in children with a variety of hematologic disorders.

A comparison of laparoscopic and traditional open splenectomy in childhood

This study aimed to determine whether laparoscopic splenectomy is more advantageous than open splenectomy in pediatric patients. Data from 61 patients treated between June 1983 and September 1994 were reviewed. Length of hospitalization, hospital costs, operating time, and postoperative complications were evaluated. Forty-seven patients had open splenectomy. Nineteen of these underwent concomitant procedures. Fourteen patients had laparoscopic splenectomy, and four had concomitant cholecystectomy. The data show a trend toward a 1-day reduction in hospital stay associated with laparoscopic splenectomy (P < .02). Operating time was 83% longer for the laparoscopic approach (P < .001), and operating costs were almost $3,000 more (P < .001) than for open splenectomy. The total hospital cost also was greater for laparoscopic procedures (P < .1), primarily reflective of a more than $3,000 difference for splenectomy alone (P < .02). Two of the fourteen laparoscopic patients (14%) had complications. One patient with Evan's syndrome had pneumonia that required antibiotics. Another patient required conversion to an open procedure because of poorly controlled hemorrhage from a short gastric vessel. Twelve of the open splenectomy patients (25%) had complications: atelectasis (3), fever (4), wound infection (2), pneumonia (1), laryngospasm (1), and pancreatitis (1). The authors conclude that laparoscopic splenectomy is a safe but currently more expensive alternative to open splenectomy, primarily because of the use of disposable instruments. Benefits include a shorter hospital stay, no greater risk of postoperative complications, and subjective improvement in the cosmetic result. Disadvantages include increased operating time and cost. Evaluation of larger series will be needed to determine the significance of the difference in complication rates between the two procedures.

Hand-assisted laparoscopic splenectomy

A method of performing a laparoscopic splenectomy with the aide of intraabdominal manipulation is described. We believe that this is a versatile technique that compares quite favorably with a pure cannula approach. It is likely that this approach is safer because vascular control can readily be assured by the intraabdominal operator. It is also less costly because it is more rapid than a procedure done solely by cannula techniques. Moreover, it is reproducible by an experienced general surgeon. The results appear equal in terms of access morbidity and hospitalization time to those seen with a purely laparoscopic approach. Experience with 21 splenectomies is described and compared with 20 others performed by the traditional open approach.

Laparoscopic splenectomy. The initial experience at University of California, San Francisco

OBJECTIVE

To evaluate the outcomes of patients undergoing laparoscopic splenectomy (LS) at a single institution.

DESIGN

Case control.

SETTING

University teaching hospital.

PATIENTS

The medical records of the initial 25 consecutive patients who underwent LS at a single institution were reviewed. For comparison, a control group of 25 patients undergoing open splenectomy (OS) matched for age, diagnosis, and splenic weight were also reviewed.

MAIN OUTCOME MEASURES

Data regarding operative time, blood loss, pathologic findings, complications, postoperative hospital stay, ileus duration, preoperative and postoperative hematocrit and platelet counts, blood and platelet transfusions, and hospital costs were collected.

RESULTS

Twenty-five patients underwent attempted LS. Four procedures (16%) were converted to OS. Operative time averaged 3.3 +/- 0.2 hours for LS and 2.6 +/- 0.1 hours for OS (P = .001). In the LS group, a regular diet was tolerated 2.1 +/- 0.3 days after surgery (P < .001), and mean postoperative hospital stay was 5.1 +/- 0.6 days (P = .037), compared with 4.3 +/- 0.3 and 6.7 +/- 0.5 days, respectively, in the OS group. No differences were observed in blood loss, complication rate, transfusion requirement, or hospital cost.

CONCLUSIONS

Compared with OS, LS requires more operative time, is comparable in blood loss, transfusion requirement, complication rate, and cost, and appears to be superior in terms of return of bowel function and hospital stay.

Cost-effectiveness of splenectomy versus intravenous gamma globulin in treatment of chronic immune thrombocytopenic purpura in childhood

Infusions of intravenous gamma-globulin (IVGG) are an effective, nontoxic therapy for chronic idiopathic thrombocytopenic purpura (ITP) that would be more widely accepted if the therapeutic agent were not so expensive. The costs and outcomes of managing such children with splenectomy and IVGG were modeled with Markov processes. Children unresponsive to one treatment were considered to have received the alternative. The model accounted for spontaneous remissions, therapeutic responses, traumatic events, episodes of sepsis, and operative deaths. For a 10-year-old child with chronic ITP, the strategy of initial treatment with splenectomy had associated costs of $17,000 and a 97.9% ten-year survival rate, whereas the strategy of initial treatment with IVGG had associated costs of $21,000 but a 98.6% survival rate. Each additional life saved by employing the IVGG strategy cost $540,000, or $8,000 per year for a life expectancy of 70 years. Sensitivity analyses demonstrated that for older children the IVGG strategy continued to result in improved survival rates but was more costly than the splenectomy strategy. For younger children, the IVGG strategy dominated, with improved survival rates and lower costs.
