Lessons Learned: Trapeziectomy and Suture Suspension Arthroplasty for Thumb Carpometacarpal Osteoarthritis.

In this study, we describe refinements of an accepted technique made by a single surgeon for trapeziectomy and suture suspension arthroplasty for thumb carpometacarpal (CMC) osteoarthritis after 220 cases over 4 years. Results are derived from 77 patients who underwent treatment using this technique comparing postoperative results with preoperative assessment and had sufficient data for inclusion. The surgical technique is described, including tips and modifications to avoid known possible complications. All patients in this study had advanced Eaton stage III or IV osteoarthritis. Grip strength and key pinch showed statistically significant improvement, and the improvement in palmar pinch approached significance. Pain scores were significantly decreased with over 50% of the patients rating their pain at 0 postoperatively. The overall complication rate was very low, and improvements in technique were made to mitigate future occurrence. This surgical technique for the treatment of thumb CMC arthritis achieved pain relief and recreated ligamentous support of the base of the first metacarpal to resist proximal migration after trapeziectomy, providing an increase in grip strength and key pinch with return of range of motion early in the postoperative period. Refinements on this technique through a large volume single surgeon experience provide technical tips for optimizing outcomes.

Migraine Treatment.

Migraine headaches affect more than 35 million Americans and are ranked the third-highest cause of disability worldwide, resulting in decreased quality of life and serious economic consequences. There are 4 types of migraine headaches: frontal, temporal, occipital, and rhinogenic. Each type has a well-described trigger site. Migraines headaches often are refractory to medical therapy and may respond well to botulinum toxin type A. Migraine surgery is another option to release trigger sites. A systematic review of the migraine surgery literature found an average success rate of 90%, with elimination or greater than 50% improvement of migraine headaches after migraine surgery.

Case Report of Clinical Vignette: Osteopetrosis.

INTRODUCTION: Osteopetrosis is a connective tissue disorder resulting from abnormally dense bone predisposing patients to fracture. The clinical pattern of fractures across time and space as well as suggestive radiographic findings usually raises diagnostic suspicion. Multiple genetic mutations resulting in dysfunctional osteoclasts have been implicated in the pathogenesis of osteopetrosis with variable inheritance patterns. In severe cases, usually inherited in an autosomal recessive pattern, the medullary cavity important in the production of normal blood cell progenitors is replaced by defective endochondral bone, leading to pancytopenia and consequential extramedullary hematopoiesis. MATERIALS AND METHODS: This is a case report from a patient presenting to Naval Medical Center San Diego, a large Military Treatment Facility constituting a regional referral center for Navy Medicine West and serving approximately 250,000 eligible patients with more than 6,200 military and civilian staff. The genetic analysis was performed by Connective Tissue Gene Tests (CTGT) using the CTGT Osteopetrosis NextGen sequencing panel, consisting of 13 genes associated with osteopetrosis. A literature review was performed using PUBMED and Google Scholar to identify information on osteopetrosis and mutation implications. RESULTS: We present a 19-year-old male with clinical osteopetrosis resulting from compound heterozygosity of several mutated alleles within the PLEKHM1 gene, which is important to endosomal and lysosomal vesicular function. To date, most mutations discovered involve genes coding for intracellular enzymes, like carbonic anhydrase, or cell surface transporters, such as the osteoclast H+-ATPase proton pump and the chloride channel, engaged in the acidification of bone at the interface of the osteoclastic ruffled border and the bone matrix. This case represents one of the few reports of inherited defects within the PLEKHM1 gene, resulting in defective osteoclastic ruffled border formation and consequential inadequate bone resorption. CONCLUSIONS: This patient's lack of hematologic deficiencies and survival into adulthood portend an improved long-term prognosis and may infer prognostic insight in future cases with similar genetic abnormalities. In patients presenting with skeletal abnormalities and pathologic fractures in early adulthood, the clinician should consider osteopetrosis as a potential explanatory mechanism. Genetic characterization can elucidate cellular pathophysiology and potentially guide treatment modalities. Patients are typically managed with lifestyle adjustments limiting traumatic fracture and antiresorptive medications, typified by the bisphosphonate class. Since osteoclasts derive from a hematopoietic precursor, the only definitive curative therapy present is hematopoietic stem cell transplant. In the future, novel genomic level modulation may confer the ability to correct underlying point mutations and spare individuals from the morbidity associated with bone marrow transplant.

Trapeziectomy Arthroplasty With Suture Suspension: Short- to Medium-Term Outcomes From a Single-Surgeon Experience.

PURPOSE: To describe the technique and a single-surgeon experience with a suture suspension and first dorsal compartment release treatment for thumb trapeziometacarpal (TMC) osteoarthritis. METHODS: We performed 19 procedures on 18 patients using this technique and compared results with preoperative assessment. At an average of 20 months (range, 8-45 months) after surgery, standard measures after TMC joint arthroplasty were performed. RESULTS: All patients had advanced Eaton stage III or IV osteoarthritis. Grip strength, key pinch, and thumb abduction showed statistically significant increases of 7 kg, 0.7 kg, and 4°, respectively. Seventeen of 18 patients no longer had reports of TMC joint pain on follow-up. There was one reoperation for pain because of osteophytes at the ulnar surface of the thumb metacarpal base, which resolved with proximal metacarpal excision. One case of index metacarpal fracture was treated with an orthosis. CONCLUSIONS: This surgical technique for the treatment of thumb TMC joint arthritis achieved pain relief and recreated support of the base of the metacarpal to resist proximal migration or radial deviation. This technique also provided an increase in grip strength and key pinch with return of range of motion early in the postoperative period. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Using Self-Guided Treatment Software (ePST) to Teach Clinicians How to Deliver Problem-Solving Treatment for Depression.

Problem-solving treatment (PST) offers a promising approach to the depression care; however, few PST training opportunities exist. A computer-guided, interactive media program has been developed to deliver PST electronically (ePST), directly to patients. The program is a six-session, weekly intervention modeled on an evidence-based PST protocol. Users are guided through each session by a clinician who is presented via hundreds of branching audio and video clips. Because expert clinician behaviors are modeled in the program, not only does the ePST program have the potential to deliver PST to patients but it may also serve as a training tool to teach clinicians how to deliver PST. Thirteen social workers and trainees used ePST self-instructionally and subsequently attended a day-long workshop on PST. Participants' PST knowledge level increased significantly from baseline to post-ePST (P = .001) and did not increase significantly further after attending the subsequent workshop. Additionally, attending the workshop did not significantly increase the participants' skill at performing PST beyond the use of the ePST program. Using the ePST program appears to train novices to a sufficient level of competence to begin practicing PST under supervision. This self-instructional training method could enable PST for depression to be widely disseminated, although follow-up supervision is still required.

Shape-based reprofiling of FDA-approved drugs for the H1 histamine receptor.

Reprofiling of existing drugs to treat conditions not originally targeted is an attractive means of addressing the problem of a decreasing stream of approved drugs. To determine if 3D shape similarity can be used to rationalize an otherwise serendipitous process, we employed 3D shape-based virtual screening to reprofile existing FDA-approved drugs. The study was conducted in two phases. First, multiple histamine H(1) receptor antagonists were identified to be used as query molecules, and these were compared to a database of approved drugs. Second, the hits were ranked according to 3D similarity and the top drugs evaluated in a cell-based assay. The virtual screening methodology proved highly successful, as 13 of 23 top drugs tested selectively inhibited histamine-induced calcium release with the best being chlorprothixene (IC(50) 1 nM). Finally, we confirmed that the drugs identified using the cell-based assay were all acting at the receptor level by conducting a radioligand-binding assay using rat membrane.

The role of phenotyping in chronic prostatitis/chronic pelvic pain syndrome.

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a chronic pain syndrome identified by the presence of noninfectious pelvic or perineal pain lasting longer than 3 months. Current diagnoses and treatments for the syndrome solely depend on and target symptoms, respectively. Thus far, the mechanistic disturbances responsible for the pathogenesis of CP/CPPS have remained largely elusive and treatments, and therefore, continue to be ineffective. To move toward successful management and treatment of CP/CPPS, it is necessary to elicit the underlying biological mechanisms responsible for the syndrome. Therefore, a phenotyping system that is able to bridge the gap between current symptom-based diagnosis and future mechanistic approaches to diagnosis and treatment is needed. In this article, we examine current CP/CPPS phenotyping systems, analyze their utility, and make suggestions for changes in clinical approaches to the syndrome that would both promulgate a mechanistic understanding and advance treatment approaches.

Lower extremity compartment syndrome in the acute care surgery paradigm: safety lessons learned.

BACKGROUND: Prompt diagnosis and decompression of acute lower extremity compartment syndrome (LECS) in the multisystem injured patient is essential to avoid the devastating complications of progressive tissue necrosis and amputation. Despite collaborative trauma and orthopedic management of these difficult cases, significant delays in diagnosis and treatment occur. Periodic system review of our trauma and orthopedic data for complications of LECS led us to hypothesize that delayed diagnosis and limb loss were potentially preventable events in our trauma center. SETTING: Academic level 1 trauma center. METHODS: We performed a prospective review of our trauma registry for all cases of LECS over a 7 year period (2/98-10/2005). Variables reviewed included demographics, injury patterns, tissue necrosis, amputation and mortality. RESULTS: Eighty-three (10 female, 73 male) cases were reviewed. Mean age = 33.3 years (range 1-78). Mean ISS = 19.4, GCS = 12.5. Five (6.0%) had amputations; 7 (8.4%) died. Fractures occurred in 68.7% (n = 57), and vascular injuries were present in 38.6% (n = 32). In 7 patients (8.4%), a delayed compartment release resulted in muscle necrosis requiring multiple debridements, subsequent wound closure problems, and long term disability. Of note, none of these patients had prior compartment pressure measurements. Furthermore, 6 patients (7%) had superficial peroneal nerve transections as complications of their fasciotomy. CONCLUSION: In the multisystem injured patient, LECS remains a major diagnostic and treatment challenge with significant risks of limb loss as well as complications from decompressive fasciotomy. These data underscore the importance of routine surveillance for LECS. In addition, a thorough knowledge of regional anatomy is essential to avoid technical morbidity.

Postinjury life threatening coagulopathy: is 1:1 fresh frozen plasma:packed red blood cells the answer?

BACKGROUND: Recent military experience suggests that immediate 1:1 fresh frozen plasma (FFP); red blood cells (RBC) for casualties requiring >10 units packed red blood cells (RBC) per 24 hours reduces mortality, but no clinical trials exist to address this issue. Consequently, we reviewed our massive transfusion practices during a 5-year period to test the hypothesis that 1:1 FFP:RBC within the first 6 hours reduces life threatening coagulopathy. METHODS: We queried our level I trauma center's prospective registry from 2001 to 2006 for patients undergoing massive transfusion. Logistic regression was used to evaluate the independent effect of FFP:RBC in 133 patients who received >10 units RBC in 6 hours on (1) Coagulopathy (international normalized ratio [INR] >1.5 at 6 hours), controlling for our previously described risk factors predictive of coagulopathy, as well as RBC, FFP, and platelet administration (2) Death (controlling for all variables plus age, crystalloids per 24 hours, INR >1.5 at 6 hours). RESULTS: Overall mortality was 56%; 50% died from acute blood loss in the operating room. Over 80% of the RBC transfusions were completed in the first 6 hours: (Median RBC: 18 units) Median FFP:RBC survivors, 1:2, nonsurvivors: 1:4. (p < 0.001) INR >1.5 at 6 hours occurred in 30 (23%); 81% died. Regarding mortality, logistic regression showed significant variables (p < 0.05) included: RBC per 6 hours (OR = 1.248, 95%CI: 1.957-53.255), INR at 6 hours >1.5 (OR = 10.208, 95% CI: 1.957-53.255), ED temperature <34 degrees C (OR = 15.491, 95% CI 1.376-174.396), and age >55 years (OR = 40.531, CI 5.315-309.077). The adjusted OR for FFP:RBC ratio including the quadratic term was found to follow a U-shaped association (quadratic term estimate 0.6737 +/- 0.0345, p = 0.0189). CONCLUSION: Although our data suggest that 1:1 FFP:RBC reduced coagulopathy, this did not translate into a survival benefit. Our findings indicate that the relationship between coagulopathy and mortality is more complex, and further clinical investigation is necessary before recommending routine 1:1 in the exsanguinating trauma patient.

Outcomes in surgical versus medical patients with the secondary abdominal compartment syndrome.

BACKGROUND: Secondary abdominal compartment syndrome (SACS) is a well-recognized sequelae of massive fluid resuscitation in surgical patients, but has only anecdotally been reported in the medical patient population. The purpose of this study was to compare the clinical scenarios, physiologic indices, and outcomes of patients with SACS due to medical versus trauma etiologies. METHODS: Patients undergoing decompression for SACS from January 1999 to January 2006 were identified using our computerized operative records. RESULTS: During the 7-year study period, 54 patients developed SACS (41 postinjury patients and 13 medical patients). There were no significant differences in demographics, physiologic indices, or fluid resuscitation between the medical and postinjury groups: age (46.6 +/- 4.7 vs 40.6 +/- 2.3), bladder pressure (33.5 +/- 1.1 vs 32.8 +/- 1.8), peak airway pressures (45.9 +/- 2.4 vs 49.3 +/- 2.1), base deficit (14.6 +/- 1.4 vs 13.6 +/- 1.1), and fluids (18.5 +/- 1.8 vs 16.0 +/- 1.5 liters). Patients with a medical cause of SACS had a significantly longer time to decompression (21 +/- 3.6 versus 6.5 +/- 1.9 hours), significantly higher incidence of MOF (62% v 27%), and trend toward greater mortality (54% versus 34%). CONCLUSIONS: Patients with diverse disease processes may develop SACS. Despite similar age and physiologic indices, the MOF and mortality rates associated with medical SACS are markedly higher. These findings highlight the need for routine monitoring in at-risk patients, prevention of pathologic intra-abdominal hypertension, and a low threshold for decompression.

Orchiectomy as a result of ischemic orchitis after laparoscopic inguinal hernia repair: case report of a rare complication.

BACKGROUND: Ischemic orchitis is an established complication after open inguinal hernia repair, but ischemic orchitis resulting in orchiectomy after the laparoscopic approach has not been reported. CASE PRESENTATION: The patient was a thirty-three year-old man who presented with bilateral direct inguinal hernias, right larger than left. He was a thin, muscular male with a narrow pelvis who underwent bilateral extraperitoneal mesh laparoscopic inguinal hernia repair. The case was complicated by pneumoperitoneum which limited the visibility of the pelvic anatomy; however, the mesh was successfully deployed bilaterally. Cautery was used to resect the direct sac on the right. The patient was discharged the same day and doing well with minimal pain and swelling until the fourth day after surgery. That night he presented with sudden-onset pain and swelling of his right testicle and denied both trauma to the area and any sexual activity. Ultrasound of the testicle revealed no blood flow to the testicle which required exploration and subsequent orchiectomy. CONCLUSION: Ischemic orchitis typically presents 2-3 days after inguinal hernia surgery and can progress to infarction. This ischemic injury is likely due to thrombosis of the venous plexus, rather than iatrogenic arterial injury or inappropriate closure of the inguinal canal. Ultrasound/duplex scanning of the postoperative acute scrotum can help differentiate ischemic orchitis from infarction. Unfortunately, testicular torsion cannot be ruled out and scrotal exploration may be necessary. Although ischemic orchitis, atrophy, and orhiectomy are uncommon complications, all patients should be warned of these potential complications and operative consent should include these risks irrespective of the type of hernia or the surgical approach.

Cervical spine fracture patterns mandating screening to rule out blunt cerebrovascular injury.

BACKGROUND: Aggressive screening for blunt cerebrovascular injury (BCVI) and prompt anticoagulation for documented injuries has resulted in a significant reduction in ischemic neurologic events. An association between vertebral artery injuries (VAIs) and specific cervical spine fracture patterns has been suggested; however, current screening guidelines would subject all patients with cervical spine fractures to imaging because no distinction has been made for carotid artery injuries (CAIs). We hypothesized that specific cervical spine fracture patterns that warrant screening evaluation exist, hence limiting unwarranted diagnostic imaging. METHODS: Patients undergoing screening for BCVI on the basis of injury patterns and mechanism have been prospectively followed at our regional trauma center since January 1996. RESULTS: During the study period from January 1996 to January 2005, there were 17,007 blunt trauma admissions. Twenty-three patients presented with symptoms of BCVI. Screening angiography was performed in 766 patients (4.5%), and diagnosed 258 (34%) patients with BCVI. One hundred twenty-five patients with BCVI had cervical spine fractures; 18 patients had isolated CAI; 84 had isolated VAI, and 23 had combined CAI and VAI. Eight patients with VAI had minor cervical fractures but underwent screening for other injury patterns. Fractures in the remaining patients with BCVI were 1 of 3 patterns. Subluxations in 56 (48%) patients, C1 to C3 cervical spine fractures in 42 (36%), or extension of the fracture through the foramen transversarium in 19 (16%). Cervical spine fractures were the sole indication for screening in 90% of the study population. Screening yield of all patients admitted with 1 of these 3 fracture patterns was 37%. CONCLUSIONS: Blunt cerebrovascular injury is associated with complex cervical spine fractures that include subluxation, extension into the foramen transversarium, or upper C1 to C3 fractures. Patients sustaining such cervical fractures should undergo prompt screening.

One hundred percent fascial approximation with sequential abdominal closure of the open abdomen.

BACKGROUND: Damage-control surgery and the recognition of the abdominal compartment syndrome have improved patient outcomes but at the cost of an open abdomen. Multiple techniques have been introduced to obtain fascial closure for the open abdomen to minimize morbidity and cost of care. We performed a modification of the vacuum-assisted closure (VAC) technique that provided constant fascial tension, hypothesizing this would result in a higher rate of primary fascial closure. METHODS: After initial temporary closure of the abdomen after post-injury damage control or decompressive laparotomy for abdominal compartment syndrome, we began the sequential closure technique. The technique begins by covering the bowel with the multiple white sponges overlapped like patchwork, and the fascia is placed under moderate tension over the white sponges with #1-PDS sutures. Large black VAC sponges are placed on top of the white sponges and affixed with an occlusive dressing and standard suction tubing is placed. Patients are returned to the operating room for sequential fascial closure and replacement of the sponge sandwich every 2 days, with a resulting decrease in the fascial defect. RESULTS: Fourteen patients underwent sequential abdominal closure during the study period: 9 owing to damage control surgery and 5 owing to secondary abdominal compartment syndrome. Average time to closure was 7.5 +/- 1.0 days (range 4-16) and average number of laparotomies to closure was 4.6 +/- 0.5 (range 3-8). All patients attained primary fascial closure. CONCLUSION: We propose a modification of the previously described vacuum-assisted closure technique that achieves 100% fascial approximation in our limited experience. Further application and refinement of this technique may eliminate the need for delayed complex and costly reconstructive abdominal wall procedures for the open abdomen.

Synthesis and SAR of 1,3-disubstituted cyclohexylmethyl urea and amide derivatives as non-peptidic motilin receptor antagonists.

A series of 1,3-disubstituted cyclohexylmethyl urea and amide derivatives were synthesized as motilin receptor antagonists. Starting from known motilin antagonists, 1a and 1b, the cyclopentene scaffold was replaced and the four recognition elements optimized to arrive at a potent novel series.

Complications of nonoperative management of high-grade blunt hepatic injuries.

BACKGROUND: Nonoperative management of blunt hepatic injuries is highly successful. Complications associated with high-grade injuries, however, have not been well characterized. The purpose of the present study was therefore to define hepatic-related complications and associated treatment modalities in patients undergoing nonoperative management of high-grade blunt hepatic injuries. METHODS: Three hundred thirty-seven patients from two regional Level I trauma centers with grade 3 to 5 blunt hepatic injuries during a 40-month period were reviewed. Complications and treatment of hepatic-related complications in patients not requiring laparotomy in the first 24 hours were identified. RESULTS: Of 337 patients with a grade 3 to 5 injury, 230 (68%) were managed nonoperatively. There were 37 hepatic-related complications in 25 patients (11%); 63% (5 of 8) of patients with grade 5 injuries developed complications, 21% (19 of 92) of patients with grade 4 injuries, but only 1% (1 of 130) of patients with grade 3 injuries. Complications included bleeding in 13 patients managed by angioembolization (n = 12) and laparotomy (n = 1), liver abscesses in 2 patients managed with computed tomography-guided drainage (n = 2) and subsequent laparotomy (n = 1). In one patient with bleeding, hepatic necrosis followed surgical ligation of the right hepatic artery and required delayed hepatic lobectomy. Sixteen biliary complications were managed with endoscopic retrograde cholangiopancreatography and stenting (n = 7), drainage (n = 5), and laparoscopy (n = 4). Three patients had suspected abdominal sepsis and underwent a negative laparotomy, whereas an additional three patients underwent laparotomy for abdominal compartment syndrome. CONCLUSION: Nonoperative management of high-grade liver injuries can be safely accomplished. Mortality is low; however, complications in grade 4 and 5 injuries should be anticipated and may require a combination of operative and nonoperative management strategies.

Screening for blunt cerebrovascular injuries is cost-effective.

BACKGROUND: Recent reports have argued that screening for blunt carotid injury is futile and have called for a cost analysis. Our data previously supported screening asymptomatic trauma patients for blunt cerebrovascular injury (BCVI) to prevent associated neurologic sequelae. Our hypothesis is that aggressive angiographic screening for BCVI based on a patient's injury pattern and symptoms allows for early diagnosis and treatment and is cost-effective because it prevents ischemic neurological events (INEs). METHODS: Beginning in January 1996, we began comprehensive screening using 4-vessel cerebrovascular angiography based on injury patterns; these patients have been followed-up prospectively. Patients without contraindications received antithrombotic therapy immediately for documented BCVI. RESULTS: From January 1996 through June 2004, there were 15,767 blunt-trauma patient admissions to our state-designated level I urban trauma center, of which 727 patients underwent screening angiography. Twenty-one patients presented with signs or symptoms of neurologic ischemia before diagnosis. BCVI was identified in 244 patients (34% screening yield); the majority were men (68%) with a mean age of 35 +/- 3.7 years and mean Injury Severity Score of 28 +/- 3.8. Asymptomatic patients (n = 187) were treated (heparin in 117, low molecular-weight heparin in 11, and antiplatelet in 59); 1 patient had a stroke (0.5%). Using estimated stroke rate by grade of injury, we averted neurologic events in 32 asymptomatic patients with antithrombotic treatment. Of the 48 asymptomatic patients who did not receive adequate anticoagulation, 10 (21%) had an INE. Patients with BCVI-related neurologic events had a statistically higher percentage requiring discharge to rehabilitation facilities (50% vs. 77% for carotid artery injury [CAI]), a higher percentage requiring rehabilitation for BCVI-related stroke (0% vs. 55% for CAI), and a higher stroke-related mortality rate (0% vs. 21% for CAI and 0% vs. 17% for vertebral artery injury) than those without neurologic events. CONCLUSIONS: The cost of long-term rehabilitation care and human life after BCVI-associated neurologic events is substantial. Surgeons caring for the multiply injured should screen for carotid and vertebral artery injuries in high-risk patients.

Can we afford to do laparoscopic appendectomy in an academic hospital?

BACKGROUND: Multiple studies have shown laparoscopic appendectomy to be safe for both acute and perforated appendicitis, but there have been conflicting reports as to whether it is superior from a cost perspective. Our academic surgical group, who perform all operative cases with resident physicians, has been challenged to reduce expenses in this era of cost containment. We recognize resident training is an expensive commodity that is poorly reimbursed, and hypothesized laparoscopic appendectomy was too expensive to justify resident teaching of this procedure. The purpose of this study was to determine if laparoscopic appendectomy is more expensive than open appendectomy. METHODS: From April 2003 to April 2004, all patients undergoing appendectomy for presumed acute appendicitis at our university-affiliated teaching hospital were reviewed; demographic data, equipment charge, minutes in the operating room (OR), hospital length of stay, and total hospital charge were analyzed. OR minute charges were gradated based on equipment use and level of skilled nursing care. Conversions to open appendectomy were included in the laparoscopic group for analysis. RESULTS: During the study period, 247 patients underwent appendectomy for preoperative diagnosis of acute appendicitis, with 152 open (113 inflamed, 37 perforated, 2 normal), 88 laparoscopic (69 inflamed, 12 perforated, 7 normal), and 7 converted (2 inflamed, 4 perforated, 1 normal) operations performed. The majority were men (67%) with a mean age of 31.4 +/- 2.2 years. Overall, there was significant difference (P < .05) in intraoperative equipment charge (125.32 dollars +/- 3.99 dollars open versus 1,078.70 dollars +/- 24.06 dollars lap), operative time charge (3,022.16 dollars +/- 57.51 dollars versus 4,065.24 dollars +/- 122.64 dollars), and total hospital charge (12,310 dollars +/- 772 dollars versus 16,773 dollars +/- 1,319 dollars) but no significant difference in operative minutes (56.3 +/- 1.3 versus 57.4 +/- 2.3), operating room minutes (90.5 +/- 1.7 versus 95.7 +/- 2.5), or hospital days (2.6 versus 2.2). In subgroup analysis of patients with uncomplicated appendicitis, open and laparoscopic groups had equivalent hospital days (1.47 versus 1.49) but significantly different hospital charges (9,632.44 dollars versus 14,251.07 dollars). CONCLUSIONS: Although operative time was similar between the 2 groups, operative and total hospital charges were significantly higher in the laparoscopic group. Unless patient factors warrant a laparoscopic approach (questionable diagnosis, obesity), we submit open appendectomy remains the most cost-effective procedure in a teaching environment.
