RESUMO
STUDY OBJECTIVE: To examine the recurrence rates of pediatric benign ovarian neoplasms METHODS: A retrospective review of females up to 21 years of age who underwent surgery for a benign ovarian neoplasm at 8 pediatric hospitals from January 2010 through December 2016 was conducted. Data include primary operation details, follow-up imaging, and reoperation details. RESULTS: Four hundred and twenty-six females were included in our cohort, with a median age of 15 years at the time of the primary operation. Of the patients, 69% had a mature teratoma, 18% had a serous cystadenoma, and 8% had a mucinous cystadenoma. Two-thirds of patients underwent ovarian-sparing surgery. There were 11 pathologically confirmed recurrences (2.6%) at a median follow-up of 12.8 months. The pathologically confirmed recurrence was 10.5 per 100 person-months at 12 months (SE = 5.7) for mucinous cystadenomas and 0.4 months (SE = 0.4) for mature teratomas (P = .001). For half of the patients, the pathologically confirmed recurrences occurred by 12.8 months, and for 75%, they occurred by 23.3 months. There were no differences in reoperation or recurrence on the basis of initial procedure (ovary-sparing surgery vs oophorectomy). CONCLUSION: We measured the pathologically confirmed recurrence rate for pediatric benign ovarian neoplasms in a large cohort. Oophorectomy was not protective against recurrence. Mucinous cystadenomas were at a greater risk of pathologically confirmed recurrence.

Oroxylum indicum is a traditionally used plant in Ayurvedic and folk medicines. The plant is useful for the management of gastrointestinal diseases as well as skin diseases. In the present study, we analyzed the antitumor potential of O. indicum in Dalton's lymphoma ascites tumor cells (DLA) and Ehrlich ascites carcinoma (EAC)-induced solid and ascites tumors. Further, the potential of O. indicum extract (OIM) on skin papilloma induction by dimethyl benz(a) anthracene (DMBA) and croton oil was evaluated. The chemical composition of the extract was analyzed using UPLC-Q-TOF-MS. The predominant compounds present in the extract were demethoxycentaureidin 7-O-rutinoside, isorhamnetin-3-O-rutinoside, baicalein-7-O-glucuronide, 5,6,7-trihydroxyflavone, 3-Hydroxy-3',4',5'-trimethoxyflavone, 5,7-dihydroxy-3-(4-methoxyphenyl) chromen-4-one, and 4'-Hydroxy-5,7-dimethoxyflavanone. Treatment with high-dose OIM enhanced the percentage of survival in ascites tumor-bearing mice by 34.97%. Likewise, high and low doses of OIM reduced the tumor volume in mice by 61.84% and 54.21%, respectively. Further, the skin papilloma formation was brought down by the administration of low- and high-dose groups of OIM (by 67.51% and 75.63%). Overall, the study concludes that the Oroxylum indicum root bark extract is a potentially active antitumor and anticancer agent.

STUDY OBJECTIVE: To evaluate failure of initial operative therapy (incomplete tumor removal) of ovarian-sparing surgery for pediatric benign ovarian neoplasms. METHODS: A retrospective review of patients up to 21 years of age who underwent ovarian-sparing surgery for a benign ovarian neoplasm from 2010 to 2016 at 8 pediatric hospitals was conducted. Failure of initial operative therapy is defined as a radiologically suspected or pathologically confirmed ipsilateral lesion with the same pathology as the primary neoplasm within 12 weeks of the initial operation. RESULTS: Forty patients received imaging within 12 weeks of their primary operation. Sixteen (40%) patients had a radiologically identified ovarian abnormality ipsilateral to the primary lesion, and 5 patients were suspected to have the same lesion as their primary neoplasm. Three of the 5 patients (7.5%) underwent reoperation with pathologic confirmation of the same lesion, resulting in a pathologically confirmed failure of therapy rate of 7.5%. The other 2 patients had serial imaging that subsequently demonstrated no recurrence with lesion resolution. Age, race/ethnicity, laparoscopy vs laparotomy, presence of torsion, pathology, size of lesion, and surgeon specialty were not associated with failure of therapy. CONCLUSION: In most patients who received imaging within 12 weeks of the primary operation for resection of a benign ovarian neoplasm, ovarian-sparing surgery was successful in complete tumor removal, with a low failure of therapy rate. Selected patients with suspected failure of therapy on initial imaging could be serially monitored to determine the need for repeat surgical intervention.

OBJECTIVE: This paper presents the case of a traumatic tracheal rupture in a pediatric patient. The body of literature of the clinical features, evaluation, and management of this uncommon presentation is discussed. CASE: A 13-year-old boy sustained an intrathoracic tracheal rupture whilst playing Australian Rules football. He developed hallmark clinical features of air extravasation and was intubated prior to transfer to a tertiary pediatric center for further management. After a short trial of conservative management, his respiratory status deteriorated and he was taken to the operating theater for open surgical repair of the defect. CONCLUSION: Traumatic rupture of the trachea is a rare injury in children. This case demonstrates the dynamic nature of this serious injury and the need for multidisciplinary care in achieving the optimal outcome.

STUDY OBJECTIVE: To assess postoperative management of pediatric patients with benign ovarian neoplasms, to develop recommendations for postoperative care. DESIGN: A retrospective cohort study. SETTING: Eight pediatric hospitals in the midwestern United States. PARTICIPANTS: Patients up to 21 years of age who underwent surgery for a benign ovarian neoplasm between January 2010 and December 2016 were included. INTERVENTIONS: No prospective interventions were evaluated. MAIN OUTCOME MEASURES: Main outcome measures included postoperative imaging findings, recurrence rates, reoperation rates, and the timing of the aforementioned results. RESULTS: A total of 427 patients met inclusion criteria. After the index surgery, 155 patients (36%) underwent a routine imaging study. Among those with routine imaging, abnormalities were noted in 48 patients (31%); 7 went on to have reoperation (5%), and no malignant pathologies or torsion were identified. Excluding the 7 patients who went on to have a reoperation as a result of routine imaging, 113 patients developed symptoms postoperatively and underwent imaging as a result (27%, 113/420). Abnormalities were noted in 44 (10%); 15 of these patients underwent reoperation (4%), among them 2 with malignancies and 3 with torsion. Of these 44 patients, 23 had initially undergone routine imaging and subsequently went on to have symptomatic imaging, with 17% (4/23) undergoing reoperation. CONCLUSIONS: Routine imaging did not identify malignancy; most lesions identified on routine imaging were incidental findings. Although the study was not powered to appreciate a statistically significant difference, patients with malignancy or torsion were identified in the symptomatic group. This suggests no benefit from routine imaging, and supports symptomatic imaging postoperatively to minimize costs and patient/family burden.

Long-acting reversible contraceptives are the most effective methods to prevent pregnancy and also offer noncontraceptive benefits such as reducing menstrual blood flow and dysmenorrhea. The safety and efficacy of long-acting reversible contraception are well established for adolescents, but the rate of use remains low for this population. The pediatrician can play a key role in increasing access to long-acting reversible contraception for adolescents by providing accurate patient-centered contraception counseling and by understanding and addressing the barriers to use.

BACKGROUND: Oroxylum indicum Vent., a Dasamula plant used in Ayurveda possesses antioxidant properties. OBJECTIVES: To evaluate the cardioprotective effect of 70% methanolic extract of O. indicum Vent. root bark (OIM) against doxorubicin induced cardiomyopathy in female Sprague Dawley rats. MATERIALS AND METHODS: Cardiotoxicity was induced by intra-peritoneal injection of doxorubicin 30 mg/kg body weight (b.w.) for 4 consecutive days after a ten-day pre-treatment of animals with OIM at 200 mg/kg b.w. and 400 mg/kg b.w (p.o.). Drug treatment continued up to day 14. Probucol, orally administered at a dose of 20 mg/kg b.w. served as standard. ECG was recorded. The animals were sacrificed on day 15 and comparative analysis of serum marker levels of creatine phosphokinase (CPK), lactate dehydrogenase (LDH), Serum Glutamate Oxaloacetate Transaminase (SGOT), Serum Glutamate Pyruvate Transaminase (SGPT), tissue antioxidant status based on Superoxide Dismutase (SOD), Glutathione Peroxidase (GPx), reduced Glutathione (GSH) and lipid peroxidation (LPO) was carried out. Histopathological examination was carried out using hematoxylin-eosin staining. RESULTS: ECG records of OIM treated animals showed normal pattern, in comparison to the control with ST depression and arrhythmia in cardiogram. Tissue antioxidant profile (SOD, GSH and GPx) was significantly (p < 0.01) elevated in the cardiac tissue of treated group in dose-dependent manner; lipid peroxidation level was found to decrease with treatment. Comparative analysis of serum markers - CPK, LDH, SGOT and SGPT - among untreated control, standard and extract treated groups revealed that OIM extract at 400 mg/kg b.w. dose significantly reduced the levels (p < 0.01). Histological analysis revealed normal myocardial architecture in OIM treated groups. HPTLC fingerprint of OIM revealed 8 bands and detected the presence of chrysin, apigenin and quercetin. CONCLUSION: O. indicum root bark shows marked cardio-protective activity, possibly due to the presence of antioxidant compounds acting synergistically.
RESUMO
OBJECTIVES: The management of pediatric mid-dermal burns is challenging. Anecdotal evidence suggests Biobrane™ (UDL Laboratories, Inc., Sugar Land, TX) may expedite epithelization, reducing the requirement for skin grafting. Our standard management for burns of this depth is Acticoat™ (Smith and Nephew, St. Petersburg, Fl, USA). No publications are known to compare Biobrane™ to Acticoat™ for treatment of mid-dermal burns. METHODS: A prospective, randomised controlled pilot study was conducted, comparing Biobrane™ to Acticoat™ for mid-dermal burns affecting ≥ 1% Total Body Surface Area (TBSA) in children. Mid-dermal burns were confirmed using Laser Doppler Imaging within 48 hours of injury. Participants were randomized to Biobrane™ with an Acticoat™ overlay or Acticoat™ alone. RESULTS: 10 participants were in each group. Median age and TBSA were similar; 2.0 (Biobrane™) and 1.5 years (Acticoat™), 8% (Biobrane™) and 8.5% TBSA (Acticoat™). Use of Biobrane™ had higher infection rates (6 children versus 1) (P = 0.057) and more positive wound swabs, although not significant (7 children versus 4) (P = 0.37). Healing time was shorter in the Biobrane™ group, this was not significant (19 days versus 26.5 days, P = 0.18). Median dressing changes were similar (5 versus 5.5) (P = 0.56). Skin grafting requirement was greater in the Acticoat™ group (7 versus 4 children, P = 0.37) and similar in % TBSA (1.75% TBSA). CONCLUSION: This pilot study suggests that the use of Biobrane™ for mid-dermal burns in children may be associated with increased risk of infection but appears to decrease the time to healing and therefore the need for skin grafting compared to Acticoat™ alone.
RESUMO
STUDY OBJECTIVE: On this study we sought to determine the relationship of bleeding disorders to iron deficiency anemia. Additionally, this study was undertaken to examine all current treatment modalities used in a menorrhagia clinic with respect to heavy menstrual bleeding management to identify the most effective options for menstrual management in the setting of an underlying bleeding disorder. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: We performed a retrospective chart review of adolescents younger than 21 years with heavy menstrual bleeding attending a multidisciplinary hematology-adolescent gynecology clinic. Information including demographic characteristics, bleeding diathesis, hematologic parameters, treatment, and the diagnosis was extracted from each chart. Subjects were grouped into 2 categories on the basis of the diagnosis of a bleeding disorder. Hemoglobin level, iron deficiency anemia, and need for transfusion were compared between a bleeding disorder and no bleeding disorder group. Subjects were grouped into categories depending on hormonal modality and treatment success of the groups were compared. RESULTS: Seventy-three subjects were tested for a bleeding disorder. Of the subjects who completed testing, 34 (46%) were diagnosed with a bleeding disorder. Thirty-nine subjects (54%) had heavy menstrual bleeding because of other causes. There was no significant difference in hemoglobin between those with and without a bleeding disorder. Iron deficiency anemia was significantly higher in subjects without a bleeding disorder. In a comparison of hormone therapy success, the levonorgestrel intrauterine device (89%, 8 out of 9 subjects) had the highest rate of menstrual suppression followed by norethindrone acetate 5-10 mg/d (83%, 5 out of 6 subjects), and the transdermal patch (80%, 4 out of 5 subjects). All subjects using tranexamic acid as well as hormonal therapy had 100% achievement of menstrual suppression. CONCLUSION: A high frequency of bleeding disorders was found in those tested. Subjects with a bleeding disorder were less likely to present with severe anemia requiring blood transfusion and less likely to have iron deficiency anemia. Although combined oral contraceptives were commonly used clinically for menstrual suppression, they were not found to be the most effective option.

OBJECTIVES: There is limited literature about physicians' adherence to 2010 Centers for Disease Control and Prevention (CDC) Sexually Transmitted Diseases Treatment Guidelines specific to specimen collection testing methods in adolescent females in the emergency setting is limited. The objectives are to (1) determine physician adherence to CDC guidelines for specimen collection/testing for chlamydia and gonorrhea, (2) determine physician characteristics associated with guideline adherence, and (3) describe physicians' knowledge of expedited partner therapy (EPT) laws. METHODS: This is a cross-sectional, anonymous, Internet-based survey of physician members of the American Academy of Pediatrics Section of Emergency Medicine. Questions addressed practice patterns and knowledge through clinical scenarios of adolescent girls. Descriptive statistics are used to report frequency. Fisher exact and χ analyses are used to compare physician subgroups: gender, years in practice, practice setting, and geographical region. RESULTS: Overall, 257 physicians responded and 231 were analyzed; 62.4% females; 46.0% in practice for ≤ 7 years; 86.2% in academic medicine. Specimen collection/testing in an asymptomatic patient were consistent with guidelines for 85.6% of respondents, but decreased to 37.4% for a symptomatic patient. Guideline adherence was not different between physician subgroups. Only 30.4% of physicians reported state EPT law knowledge. CONCLUSIONS: Adherence with the CDC guidelines for chlamydia/gonorrhea specimen collection/testing for adolescents in the emergency setting is inadequate, and EPT knowledge is poor. With increased emergency department use by adolescents, it is critical that physicians know and implement the current recommendations to improve adolescent health outcomes.

In traditional Indian medicine, the plant Gmelina arborea Linn. (GA) is described to have the ability to relieve edema. The present study evaluates the anticancer property of GA stem bark against 7,12-dimethylbenz(a) anthracene (DMBA)-croton oil-induced skin tumorigenesis along with the evaluation of anti-inflammatory activity. The observed inhibition of inflammation in carrageenan-induced (41.8%) and formalin-induced (34.07%) models may be due to inhibition of prostaglandins (PGs). Skin papilloma was induced by a single topical application of DMBA (470 nmol/200 µL acetone), followed by repeated application of croton oil (1% in 200 µL acetone). Low-concentration GA (GALC; 5% in 200 µL distilled water) and high-concentration GA (GAHC; 10% in 200 µL distilled water) were applied topically 30 min before croton oil application. The GALC and GAHC groups showed 85.7% and 57.14% tumor incidence, respectively. The number of papillomas per mouse was observed to be significantly (p ≤ 0.01) reduced in the treated groups. The onset of papilloma development was delayed considerably from 6 (control) to 12 wk (GAHC). Thus, results from the study give insights into the anticancer efficacy of Gmelina arborea, which may be due to prevention of inflammation-mediated tumor promotion by inhibiting PGs.

BACKGROUND: Gmelina arborea (GA) is widely used in traditional medicine for treating a number of ailments including gastrointestinal tract disorders. OBJECTIVE: To evaluate the gastroprotective effect of GA stem bark against ethanol-induced gastric ulcer in Wistar rats. MATERIALS AND METHODS: All animals were fasted for 36 h and received GA extract 250 and 500 mg/kg body weight (bw), 1 h before the administration of ethanol. The animals received ranitidine 50 mg/kg bw which served as the standard. The rats were sacrificed after 4 h. Then, the injuries to the gastric mucosa were estimated through gross evaluation of ulcer lesions and histology. The antioxidant parameters such as level of lipid peroxidation, superoxide dismutase (SOD), reduced glutathione (GSH), and glutathione peroxidase (GPx) in gastric tissue were also determined. RESULTS: GA treatment at a dose of 500 mg/kg bw offered 91.98% inhibition of ulcer formation, which is higher than that of ranitidine. The ethanol treatment extensively increased lipid peroxidation and it was significantly (P < 0.01) reduced in GA-treated group that eventually helped to prevent free radical accumulation. The GA enhanced the gastric mucosal antioxidant system, as indicated by a dose-dependent increase in the level/activities of GSH, GPx, and SOD. GA also attenuated the severity of histological signs of cell damage. Further, GA extract showed in-vitro 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity with IC50 value of 124.39 µg/ml. CONCLUSION: The results indicate that the gastroprotective effect of GA is probably related to its antioxidant activities that protect gastric mucosa against oxidative damage and antilipid peroxidative activity that maintain membrane integrity.
RESUMO
We conducted this study to evaluate a novel device to create a consistent and reproducible deep partial thickness burn in a porcine model. A thermostatically controlled, heated aluminium disc device was fashioned by the Biomedical Department of our institution. Contact burns were made on the flank of two Great White pigs by applying the device heated to 92°C at intervals of 5, 10, 15 and 20 seconds to four separate test areas area of skin. Biopsies for histological analysis of burn depth were taken on day 0 at 10 minutes post burn and on day 8. Biopsies taken at day 0 revealed superficial to mid-dermal burns, with minimal dermal edema and necrosis. Those from day 8 showed mid to deep dermal edema and necrosis in all four test areas following a 20 second contact duration burn. The new contact burn device was able to create a consistent deep dermal burn after 20 seconds of contact. We anticipate that this new device could be used to investigate the development of hypertrophic scarring in a porcine model.
RESUMO
OBJECTIVE: To evaluate the effect of gonorrheal and chlamydial cervicitis (GCC) on the risk of preterm labor (PTL) and preterm premature rupture of membranes (PPROM). STUDY DESIGN: A large cross-sectional sample of patients (N = 1,120) was studied. Data on samples for GCC and pregnancy outcome were entered into a database from a retrospective chart review. RESULTS: There were 1,120 pregnancies with adequate data for analysis. Of those pregnancies 933 were unaffected by GCC, and 187 were affected. The rates of preterm delivery were 17.79% and 16.58% for GCC-negative and GCC-positive pregnancies, respectively. PPROM occurred in 3.97% and 2.67% of GCC-negative and GCC-positive pregnancies, respectively. PTL occurred in 8.25% and 8.02% of GCC-negative and GCC-positive pregnancies, respectively. No outcomes met statistical significance. When pregnancy outcomes were analyzed by trimester of infection, there was a higher risk of preterm delivery but not preterm labor with earlier infection. This did meet statistical significance. There was a trend towards lower rate of cesarean section in the infected group of patients, which did not meet statistical significance. CONCLUSION: Maternal infection with gonorrhea and/or chlamydia is not associated with PPROM or PTL.

STUDY OBJECTIVE: Studies have suggested that low vitamin D levels may play a role in the pathogenesis of polycystic ovary syndrome (PCOS). The aim of our study was to compare 25-hydroxyvitamin D [25(OH)D] levels in adolescent females with and without PCOS. DESIGN, SETTING, AND PARTICIPANTS: Retrospective chart review at a tertiary care medical center for female adolescents aged 12-21 years with serum 25(OH)D measurements within a 5-year period. Participants were categorized as having PCOS or as controls based on National Institutes of Health PCOS diagnostic criteria. MAIN OUTCOME MEASURE: Exact logistic regression analysis was done to compare normal (≥30 ng/mL) vs low (<30 ng/mL) serum 25(OH)D levels in the PCOS and control groups. RESULTS: Two hundred ninety-nine charts were reviewed and 107 participants were included in the study. Of the included participants, 37 were in the PCOS group and 70 were in the control group, with a mean age of 15.2 years. In the PCOS group, 97.2% were obese and vitamin D deficiency was noted among 62.2% females. The mean serum 25(OH)D level was 18.4 and 21.6 ng/mL in PCOS and control groups, respectively. The difference in mean 25(OH)D levels between the 2 groups was not statistically significant (P > .05) when controlled for ethnicity, body mass index percentile, and season. CONCLUSION: In our study, there was no statistically significant difference in mean 25(OH)D levels between PCOS and control groups. The majority of participants in PCOS group were obese. Further studies in adolescent females with PCOS and normal body mass index could be helpful in delineating the role of vitamin D in the pathogenesis of PCOS.

INTRODUCTION: Conventional surgical debridement of burn wounds consists of tangential excision of eschar using a knife or dermabrasion until viable dermis or punctate bleeding occurs. The Versajet™ (Smith and Nephew, St. Petersburg, FL, USA) hydrosurgery system has also been advocated for burn wound debridement, with the suggestion that enhanced preservation of dermal tissue might reduce subsequent scarring. METHODS: A prospective randomised controlled trial was undertaken comparing Versajet™ to conventional debridement. After excluding those with facial burns, 61 children ≤16 years of age undergoing debridement and skin grafting for partial thickness burns were recruited. Adequacy of debridement was assessed by 2mm punch biopsies taken pre- and post-debridement. Surgical time, percentage graft take at day 10, time to healing, post-operative infection and scarring at 3 and 6 months were assessed. RESULTS: Thirty-one children underwent conventional debridement and 30 debridement using Versajet™. There was a significant difference in the amount of viable dermal preservation between the two groups (p=0.02), with more viable tissue lost in the conventional group (median 325 µm) versus the Versajet™ group (median 35 µm). There was no significant difference between graft take at day 10 (p=0.9), post-operative wound infection (p=0.5), duration of surgery (p=0.6) or time to healing after grafting (p=0.6). Despite better dermal preservation in the Versajet™ group, there was no significant difference between scarring at 3 or 6 months (p=1.0, 0.1). CONCLUSIONS: These findings suggest that Versajet™ hydrosurgery appears a more precise method of burn wound debridement. Although dermal preservation may be a factor in reducing subsequent hypertrophic scarring, there were no significant differences found between scarring at 3 or 6 months after-injury.

Scalp burns in the pediatric population appear relatively uncommon, with most reported cases occurring in adults secondary to electrical burns. We reviewed our experience with the management of these injuries in children. A retrospective review was conducted at our institution from March 2004 to July 2011. Scalp burns were defined as any burn crossing over the hairline into the scalp region. During the 7-year 4-month study, there were 107 scalp burns, representing 1.8% of the 6074 burns treated at our institution during that time. The cause was scald in 97, contact in 4, flame in 3, friction in 2, and chemical in 1. The majority (n = 93, 87%) appeared superficial to mid-dermal, with an average time to complete healing of 10.3 days. The remaining 14 cases (13%) were mid-dermal to full thickness, with an average time to complete healing of 50.8 days. Grafting was required in 12 cases (11%). The mean time to grafting was 4 weeks (range, 2 weeks to 2.5 months). The main complication of scalp burns was alopecia, which occurred in all grafted sites as well as in 4 patients treated conservatively. There were no other complications after grafting and no cases of graft loss. In our pediatric series, scalp burns were most commonly caused by scald injuries and were superficial to mid-dermal in depth. These generally healed rapidly but occasionally resulted in alopecia. The management of deep dermal and full-thickness scalp burns remains challenging in children, with the decision to graft often delayed.

Modern burn care techniques have reduced the risk of infection of the acute burn wound, resulting in more rapid healing and a lower incidence of graft loss. Secondary breakdown may still occur. The loss of epithelium in association with multifocal superficial abscesses and ulceration has been termed burns impetigo. This may result in considerable morbidity and require prolonged treatment. The events preceding development, the impact on the patient, and the ideal treatment appear unclear and poorly reported. In 5 years, between 2006 and 2011, 406 pediatric burns were treated with skin grafts, with 7% developing burns impetigo. Time to resolution ranged from 5 to 241 days: the mean time to complete healing was greatest with conservative management (96 days), followed by antibacterial dressings (37 days), oral antibiotics (36 days), topical steroids (16 days), and oral antibiotics in combination with topical steroids (13.5 days). Burns impetigo resulted in significant morbidity, requiring multiple visits to the treatment center and prolonged symptoms. Delay in diagnosis and treatment resulted in worse outcomes. Prompt consideration of burns impetigo should occur when postgraft patients present with suggestive clinical signs and treatment with oral antibiotics plus topical steroids should be considered.

INTRODUCTION: It is well supported in the literature that laparoscopic common bile duct exploration (LCBDE) for choledocholithiasis has equal efficacy when compared to ERCP followed by laparoscopic cholecystectomy. Decompression after supra-duodenal choledochotomy is common practice as it reduced the risk of bile leaks. We conducted a prospective non-randomized study to compare outcomes and length of stay in patients undergoing biliary stent insertion versus T-tube drainage following LCBDE via choledochotomy. METHODS AND PROCEDURES: The study involved 116 patients with choledocholithiasis who underwent LCBDE and decompression of the biliary system by either ante-grade biliary stent or T-tube insertion. A 7 French straight/duodenal curve biliary Diagmed™ stent (9-11 cm) was placed in 82 patients (Biliary Stent Group). T-tube insertion was used for 34 patients (T-tube group). The length of hospital stay and complications for the selected patients were recorded. All trans-cystic common bile duct explorations were excluded from the study. RESULTS: The mean hospital stay for patients who underwent ante-grade biliary stent or T-tube insertion after LBCDE were 1 and 3.4 days, respectively. This is a statistically significant result with a p value of less than 0.001. Of the T-tube group, two patients required laparoscopic washout due to bile leaks, one had ongoing biliary stasis and one reported ongoing pain whilst the T-tube was in situ. A complication rate of 11.2%, this was a significant finding. There were no complications or concerns reported for the Biliary Stent Group. CONCLUSION: Our results show that there is a significant reduction in length of hospital stay and morbidity for patients that have ante-grade biliary stent decompression of the CBD post laparoscopic choledochotomy when compared T-tube drainage. This implies that ante-grade biliary stent insertion is likely to reduce costs and increase overall patient satisfaction. We support the use of ante-grade biliary stent insertion during LCBDE when primary closure is not preferred.
