Abstract
This study reports perceived stress and associated sociodemographic factors from an international sample of adults, during the COVID-19 pandemic. The Perceived Stress Scale (PSS-10) along with socio-demographic questions were conducted between 8 April 2020 and 11 May 2020. The survey was translated from English into five languages. Recruitment was conducted worldwide using social media. A total of 1685 survey responses were collected across 57 countries with eleven countries (≥30 responses/country) included in the sub-analyses. Overall, the mean PSS-10 score was 19.08 (SD = 7.17), reflecting moderate stress compared to previously reported norms. Female gender was associated with a higher PSS score (3.03, p < 0.05) as well as four-year degree holders (3.29, p < 0.05), while adults over 75 years (-7.46, p < 0.05) had lower PSS scores. Personal care composite score (including hours of sleep, exercise, and meditation) was associated with lower PSS scores (-0.39, p < 0.01). Increases in personal care and changes in work expectations were associated with lower PSS scores (-1.30 (p < 0.05) and -0.38 (p < 0.01), respectively). Lower total PSS scores were reported in Germany (-4.82, p < 0.01) compared to the global response sample mean. This information, collected during the initial period of global mitigation orders, provides insight into potential mental health risks and protective factors during crises.

Abstract
BACKGROUND Low cost technologies are needed in resource poor rural settings for detection of pre-cancer and cancer lesions of the oral cavity. AIM The study was undertaken to investigate the feasibility of a low cost technology (Magnivisualizer) for the early detection any lesions of the oral cavity among tobacco users in a resource poor rural field setting. SUBJECTS AND METHODS A total of 1329 tobacco users were motivated to come forward for oral examination in the camp organized for this purpose. Their oral cavities were screened with a torch and Magnivisualizer by a Dentist. RESULTS With torch light, 104/1329 (7.8%) lesions were identified, though only 62/104 (59.6%) positive lesions could be differentiated into various categories. However, through Magnivisualizer 156/1329 (11.7%) lesions were detected and 153/156 (98.1%) positive lesions were differentiated into different categories. CONCLUSION Magnivisualizer offers an alternative instrument for detecting most of the early cancerous and high-grade precancerous lesions and it can be used in the rural field settings.

Abstract
In this study, we investigated and assessed the dependence of dummy head injury mitigation on the side curtain airbag and occupant distance under a side impact of a Dodge Neon. Full-scale finite element vehicle simulations of a Dodge Neon with a side curtain airbag were performed to simulate the side impact. Owing to the wide range of parameters, an optimal matrix of finite element calculations was generated using the design method of experiments (DOE); the DOE method was performed to independently screen the finite element results and yield the desired parametric influences as outputs. Also, analysis of variance (ANOVA) techniques were used to analyze the finite element results data. The results clearly show that the influence of moving deformable barrier (MDB) strike velocity was the strongest influence parameter on both cases for the head injury criteria (HIC36) and the peak head acceleration, followed by the initial airbag inlet temperature. Interestingly, the initial airbag inlet temperature was only a ~30% smaller influence than the MDB velocity; also, the trigger time was a ~54% smaller influence than the MDB velocity when considering the peak head accelerations. Considering the wide range in MDB velocities used in this study, results of the study present an opportunity for design optimization using the different parameters to help mitigate occupant injury. As such, the initial airbag inlet temperature, the trigger time, and the airbag pressure should be incorporated into vehicular design process when optimizing for the head injury criteria.

Abstract
Teeth which are present in the oral cavity of newborn infant at the time of birth are called "natal teeth" and which erupts in first month of postnatal life are called as "neonatal teeth." The incidence of these teeth is 1 in 2000 to 1 in 3500 live birth. The most common natal teeth reported are mandibular central incisors followed by maxillary incisors and mandibular canine. The natal or neonatal tooth in maxillary molar region is a rare occurrence. This article represents a rare case of bilateral neonatal maxillary molar teeth.

Abstract
Dental caries is a rapidly emerging oral health problem amongst the children of India. Its incidence in different states varies between 31 and 89%. This study was undertaken with a twin objective of assessing the prevalence of dental caries in parts of Uttaranchal state and designing the interventional strategies with a view to attend the oral health care needs of children. A total of 722 school children in the age range of 7-12 years of Nainital district were examined using WHO (1997) criteria. An overall caries prevalence of 77.7% was recorded, which is 67.26% in the age group of 7-9 years and 80.86% in 10-12 years with DMFT+deft of 1.97 and 2.61, respectively. It was observed that there were greater treatment needs in older age group. Another significant finding of the study was that the 59.96% required restorative treatment out of the various dental treatment needs evaluated.

Abstract
Albright hereditary osteodystrophy (AHO) is a rare hereditary metabolic disorder that may be associated with or without resistant to parathyroid hormone (pseudohypoparathyroidism). It is commonly characterized by a constellation of physical features of short stature, round face, short neck, and small metacarpals and metatarsals, mild mental retardation, osteoporosis, subcutaneous calcification, and sometimes olfactory and hearing functional defect. Hypocalcaemia and hyperphosphatemia are the most important manifestations of the case. We report a clinical case of siblings with AHO with reduced Gs-alpha activity and we discuss their clinical features with oral manifestations, radiographic findings, laboratory tests along with treatment.

Abstract
Dental lamina cyst, also known as gingival cyst of newborn, is a benign oral mucosal lesion of transient nature. These lesions are usually multiple but do not increase in size. Since the lesions are self-limiting and spontaneously shed a few weeks or months after birth no treatment is required. Clinical diagnoses of these conditions are important in order to avoid unnecessary therapeutic procedure and provide suitable information to parents about the nature of the lesion. In addition, it may be incorrectly diagnosed as natal teeth if present in mandibular anterior region. Here, we present a case of dental lamina cyst of newborn.

Abstract
BACKGROUND Residents often are sleep deprived after being on call. This study evaluated the effects of these sleep deficits on the acquisition of laparoscopic skills in the laboratory setting. METHODS The amount of sleep on the preceding night was recorded for 40 residents undergoing surgical skills training. The residents underwent a pretest, training, practice, and a posttest using basic (pegboard, cup drop, rope pass) and task-specific (pattern cutting, clip application, loop application) drills. Time to completion, penalty score, and total score were assessed. RESULTS Significant improvements were seen in the time and total score for all six drills, with a significant decrease in penalty scores noted for the pegboard and rope pass drills. No significant differences in skill acquisition were attributable to amount of sleep. CONCLUSION Training in the laboratory results in significant improvement of basic laparoscopic skills. Because short-term sleep deficits do not appear to hinder the acquisition of these skills, this model can be effectively applied, even after residents correct have been on call.

Abstract
The performance and ease of use of the recently introduced MRSA screen test (Denka Seiken Co. Ltd., Japan) for the identification of methicillin-resistant Staphylococcus aureus was evaluated in comparison with the BBL Crystal MRSA ID System (Becton Dickinson Europe, France). A total of 109 strains of S. aureus, consisting of 57 strains of MecA-negative S. aureus and 52 strains of MecA-positive S. aureus, were tested. With MecA PCR as the gold standard, the MRSA screen test had 98% sensitivity and 98% specificity, whereas the BBL Crystal MRSA ID System had 98% sensitivity and 95% specificity. The simplicity of use and rapid result make the MRSA screen test a valuable tool in the clinical microbiology laboratory pending demonstration of the MecA gene that should still always be done.

Abstract
BACKGROUND Controversy surrounds the need for ICU admission, prolonged bed rest, and the duration of activity restrictions for children sustaining blunt trauma. Adult literature supports management based on hemodynamic status, not CT grade. STUDY DESIGN A 3-year prospective study of a standardized management algorithm for hemodynamically normal pediatric patients with blunt liver or spleen injury was performed. Patient selection was based on vital signs, irrespective of injury grade on CT. Patients requiring ICU admission for nonliver or nonspleen injury were excluded. Patients were admitted to a surgical ward with serial hematocrit levels. Discharge occurred 48 hours postinjury if patients had no abdominal tenderness, tolerated a regular diet, and had a stable hematocrit. Patients were allowed noncontact activity, including school, after discharge. Patients were followed up at 1 month with ultrasonographic imaging. RESULTS Eighty-nine patients sustained blunt liver or spleen injury. Forty-five patients were excluded for other injuries (Glasgow Coma Scale < 13, 32 of 45); the remaining 44 patients had a mean age of 8.9 years (range 2 to 17 years), Injury Severity Score 10.6 (range 4 to 33), liver grade 2.1, and splenic injury grade 2.3. Mechanisms of injury were predominately motor vehicle collisions (59%). All patients were managed nonoperatively without transfusion; 43 of 44 patients completed the algorithm. Mean observation was 55.2 +/- 12.3 hours. One-month followup occurred in 33 of 44 patients, with one complication detected and no delayed bleeding. CONCLUSION Management of pediatric solid organ injury should be guided by hemodynamic status and not injury grade on CT. Hemodynamically normal children can be safely managed without intensive care monitoring, do not need prolonged hospitalization, and can resume school on discharge.

Abstract
Two patients, ages 72 and 71, who underwent lumbar decompressive surgery for spinal stenosis, were evaluated for postoperative sudden sensorineural hearing loss (SSHL). After two uncomplicated spinal procedures, both patients developed SSHL immediately after surgery. Hearing loss was moderate to profound in these two patients. None of the patients had a significant otologic history. Nitrous oxide administration, Valsalva maneuvers during general anesthesia, and transient drops in cerebrospinal fluid pressure stemming from spinal decompression may, in some combination, lead to an implosive force on the inner ear, causing SSHL. Further causes of postlumbar surgery SSHL may include microemboli or viral infections. SSHL is a rare but possible complication after nonotologic, noncardiac bypass surgery; only 26 cases of SSHL after this surgery have been reported. We encourage the continued reporting of sudden sensorineural hearing loss after spinal surgery.

Abstract
The aim of this study was to determine the effect of vertebral rotation, as seen in idiopathic scoliosis, on bone mineral density determination for the lumbar spine. Bone mineral content, biplanar vertebral segment area and calculated bone mineral density of each vertebra from L1 to L4 were obtained for a human cadaveric specimen. The average density for the entire L1-L4 segment was also recorded. This was done with the spine in the midline position as well as in rotation up to a maximum of 60 degrees either side of the midline. The spine was rotated in each direction using 10 degrees increments and two bone density readings were done at each rotation interval. The measured biplanar vertebral segment area increased with increasing rotation from 0 degrees to 50 degrees but decreased after 50 degrees of rotation (r = 0.73, p<0.001). The bone mineral density was significantly negatively correlated with the degree of rotation (r = -0.92, p<0.001). The decrease in measured bone mineral density was nearly 20% when the lumbar spine was rotated from neutral to 60 . This study demonstrates that degree of spinal rotation influences apparent bone mineral density by increasing the apparent vertebral segment area. The measurement change may be as high as 20%. This fact should be considered when investigating scoliotic patients with vertebral segment rotation.

Abstract
OBJECTIVE The appropriate timing, as well as the type of intervention, for the treatment of empyema in children is controversial. The advent of video-assisted thoracic surgery (VATS) has changed the way we treat these children. Therefore, we reviewed our experience with the early use of VATS in the treatment of empyema and formulated a treatment algorithm. METHODS We retrospectively reviewed medical records of all patients undergoing VATS for empyema at Arkansas Children's Hospital from December 1994 to February 1997. All patients were treated by the pediatric surgical service and had the diagnosis of empyema confirmed at surgery. Results are reported as means, unless otherwise noted. RESULTS Twenty-five children with empyema were treated with VATS during the review period. Their age was 48.3 months, and the duration of symptoms was 7.4 days. All the patients had parapneumonic empyemas and had received preoperative antibiotics for 10.1 days. Preoperative imaging included chest radiography in 25 (100%), ultrasonography in 20 (80%), and computed tomography in 10 (40%). All patients with documented loculated parapneumonic fluid collections underwent VATS within a mean of 2 days of hospitalization. Chest tubes were removed in 3.2 days, resulting in a postoperative length of stay of 4.9 days. Total length of stay was 7.3 days. One patient required conversion to minithoracotomy and required a transfusion. There were no other complications or deaths. Follow-up was available for 22 (88%) children, and there was resolution of symptoms in all children with no recurrences. CONCLUSIONS Earlier intervention with VATS in the treatment of empyema in children is safe and may reduce hospital charges by shortening hospital stay. A treatment algorithm based on early use of VATS is also described.

Abstract
BACKGROUND The limited supply of organ donors has led some groups to reconsider the role of retransplantation. Historically, except for children with malignancies, extrahepatic sources of sepsis, or severe irreversible neurologic injuries, our institution has offered all children with failing liver grafts the option of retransplantation regardless of their current severity of illness. The purpose of this study was to examine the outcome of hepatic retransplantation in children in an attempt to identify factors predictive of outcome and to assess the results of our approach to retransplantation. METHODS Between October 1984 and December 1995, 314 children less than 15 years of age underwent a total of 441 liver transplants. Data were obtained retrospectively by review of hospital records. RESULTS With a mean follow-up period of 5.3+/-2.7 years, the overall patient survival rates at 1 and 5 years were 77.1% and 67.1%, respectively. Primary allograft survival rates were 65.6% and 56.5%, respectively. Of the 137 patients who developed failure of their primary allograft, 92 underwent retransplantation (29.3% of all primary transplants). Both patient and allograft survival rates were significantly decreased after retransplantation (P<0.0001 versus primary transplants). Univariate and multivariate analysis of retransplanted patients revealed only two factors that were statistically related to patient and graft survival: age at the time of retransplantation (P<0.02 univariate and P<0.05 multivariate) and retransplantation with a reduced-size allograft (P<0.005 univariate and P<0.05 multivariate). In this series, the effect on patient survival of differences in medical condition as reflected by United Network for Organ Sharing (UNOS) status approached, but did not achieve, significance (P=0.08 for UNOS 1 versus UNOS 2 and 3). UNOS status did not affect graft survival. Neither the cause of primary allograft loss or the timing of retransplantation relative to the first transplant were related to outcome. CONCLUSIONS These data demonstrate that the failure of primary hepatic allografts remains a major problem in pediatric liver transplantation and that the overall results of retransplantation were significantly worse than those associated with primary transplants. We have identified a group of children who experienced a significantly worse outcome after retransplantation. This group consisted of children less than 3 years of age retransplanted using reduced-size grafts. Based on this finding, we now attempt to avoid retransplanting young children with reduced-size grafts. By using this approach, we hope to be able to offer children the option of retransplantation with improved results and simultaneously minimize the negative impact on patients awaiting primary transplants.

Abstract
Vancomycin-resistant Enterococcus (VRE) has become a significant nosocomial pathogen. For this study, the records of 325 patients who underwent orthotopic liver transplantation (OLT) were reviewed. Thirty-four patients were infected by VRE (incidence of 10.5%, 14% in adults vs. 5% in children, P < 0.01). Common features of patients who developed infections with VRE included previous antibiotic use (25 patients, 15 of whom received vancomycin), co-infection by other pathogens (28 patients), and relaparotomy following OLT (20 patients). Pulmonary and/or renal failure preceded infection by VRE in 11 and 4 adult patients, respectively. Biliary complications were exceedingly common in patients infected by VRE (28 patients) and significantly increased the risk of infection by VRE (21.5% vs. 3.1% for patients without biliary complications, P < 0.0001). Mortality associated with VRE infections was high (56% vs. 19% for patients not infected by VRE, P < 0.0005). The most frequent cause of death was sepsis (16 of 19 patient deaths), often polymicrobial. The high incidence of infection by VRE following OLT, the lack of effective antibiotics for the treatment of VRE, and the association of VRE with patient mortality emphasizes the need to define the risk factors associated with VRE infection. We suggest early surgical intervention to treat complications that may predispose patients to infection by VRE.

Abstract
BACKGROUND Penetrating laryngotracheal injuries are uncommon; however, these injuries are associated with significant morbidity and mortality. In an attempt to define the management of penetrating laryngotracheal injuries, we reviewed our experience with these injuries. METHODS We retrospectively analyzed the records of all patients admitted to a Level I trauma center who required operative management for penetrating laryngotracheal injuries. During the period of this study all patients with penetrating neck injuries were managed according to a protocol of selective exploration. RESULTS Of fifty-seven patients with penetrating laryngotracheal injury 32 patients sustained gunshot wounds and 25 had stab wounds. The injuries were to the larynx in 24 (42%) and trachea in 33 (58%). Forty-six (81%) had isolated airway injuries and 11 (19%) had combined airway and digestive-tract injuries. Emergent airway management in 32 (56%) patients included: tracheostomy (15), endotracheal intubation (14), and cricothyroidotomy (3). Respiratory distress and subcutaneous crepitus were the commonest clinical findings. Diagnostic evaluation included: laryngoscopy/ tracheoscopy (17), esophagoscopy (12), contrast esophagography (9), angiography (8), and bronchoscopy (3). Repair of laryngotracheal and esophageal injury was performed in the majority of patients. Selected patients with milder laryngotracheal injury did not have tracheostomy performed, with no increase in morbidity or mortality. There were 2 (3.5%) early deaths from associated major vascular injury. CONCLUSION Mortality can be minimized by aggressive airway control. Endotracheal intubation can be accomplished safely in selected patients with penetrating laryngotracheal injuries. Digestive-tract injuries can often clinically occult and contribute significantly to morbidity and mortality; therefore, early evaluation of the esophagus is vital. Simple repair of laryngotracheal and digestive-tract injuries can be performed safely with good results. In patients with minor injuries, tracheostomy does not appear to be mandatory.

Abstract
PURPOSE This study was designed to determine if p53 nuclear overexpression, as detected by immunohistochemistry, is a marker of prognostic significance in early (Stage I) colorectal cancer (CRC). METHODS Tissue sections obtained from archival blocks of 66 patients with surgically treated Stage 1 CRC were stained immunohistochemically for p53 using a monoclonal antibody (PAB 1801-Ab2). Differences in survival between p53 positive (p53+) and p53 negative (p53-) groups were compared using Kaplan-Meier survival curves and the log-rank test. RESULTS Thirty-four patients (51.5 percent) were p53+ and 32 (48.5 percent) were p53-. There were significantly more p53+ tumors in females (23 of 34) compared with males (11 of 34) (P = 0.01). Follow-up ranged from 1 to 128.5 (mean, 44.7; median, 38.2) months. Thirteen patients (19.7 percent) developed recurrence, of whom five died of disease. Univariate analysis of clinical and pathologic variables did not reveal my statistically significant differences between p53+ and p53- tumors. Mean actuarial survival was longer (48.2 months) in the p53- group compared with the p53+ group (41.5 months). However, comparison of survival curves using the log-rank test did not show a statistically significant difference in survival (log-rank chi-squared = 0.2; P = 0.6). CONCLUSION p53 nuclear overexpression does not appear to be an independent marker of prognostic significance in surgically treated early CRC. Females were more likely to have p53+ tumors. The biologic significance of this findings is unknown.

Abstract
We critically evaluated several diagnostic modalities (clinical criteria, subxiphoid pericardial window (SPW) and laparoscopy) used in the detection of occult cardiac injury in haemodynamically stable patients at high risk of cardiac injury. Over 5 years, 122 patients were admitted to a Level I trauma centre with such an injury. They sustained 69 stab wounds, and 53 gunshot wounds. Sites of penetration were: precordial (81), right chest (25), lateral chest (13), thoracoabdominal (40) and abdominal (19). Vital signs in the emergency room were (mean +/- SD): systolic BP, 111 +/- 23.2 mmHg; HR, 106 +/- 18.7; GCS, 13.6 +/- 1.3; and CVP, 17 +/- 7.8 cmH2O. SPW was performed in all patients and was positive for haemopericardium in 26 patients, 24 (92 per cent) of whom had a cardiac injury at operation. Two patients had pericardial lacerations without cardiac injury. In addition, 14 patients with lower precordial and thoracoabdominal wounds underwent laparoscopy. At laparoscopy, the pericardium was evaluated by transdiaphragmatic inspection in 10 patients. The presence (two) or absence (eight) of blood within the pericardium was accurately predicted and verified by SPW. Univariate and multiple logistic regression analysis of clinical data failed to reveal any significant predictor of cardiac injury. SPW remains the standard means of diagnosing occult cardiac injury in high-risk patients. Since the incidence of occult cardiac injury in haemodynamically stable patients is 20 per cent, SPW should be used liberally. Laparoscopy may have a role in evaluating the pericardium in the subgroup of patients with lower chest wounds, and it facilitates inspection of intra-abdominal viscera and diaphragm at the same time.

Abstract
PURPOSE This study was designed to evaluate the spectrum, clinical presentation, management, and outcome of anorectal disease in neutropenic leukemic patients and to compare operative and nonoperative management in neutropenic leukemic patients. METHODS A retrospective review of hospital records was performed. RESULTS One hundred fifty-one of 2,618 (5.8 percent) patients hospitalized with leukemia had concomitant symptomatic anorectal disease. Data from 81 patients were available for analysis. Fifty-two (64 percent) were treated nonoperatively and 29 (36 percent) underwent operative treatment. Fifty-seven (70.4 percent) had absolute neutrophil counts < 1,000/mm3, and 54 (66.7 percent) were severely neutropenic (absolute neutrophil count < 500/mm3). Management and outcomes of 54 severely neutropenic patients were analyzed. In 20 patients who underwent surgery there were 4 deaths (20 percent) and 4 recurrences (20 percent), whereas in 34 patients managed nonoperatively there were 6 deaths (18 percent) and 4 recurrences (12 percent) (P > 0.05). CONCLUSIONS Symptomatic anorectal disease afflicted 5.8 percent of hospitalized leukemic patients. In these patients, anorectal sepsis was a major source of mortality. Our data suggest that anorectal abscesses in neutropenic leukemic patients may be safely drained. Because we did not observe excessive morbidity or mortality (20 percent vs. 18 percent) in the operated neutropenic leukemics as compared with the nonoperated patients, selected neutropenic leukemic patients should not be denied anorectal surgery when otherwise indicated.

Abstract
Cephalometric characteristics of various races and ethnic groups have been described by several investigators as this information is essential for clinical and research purposes. The objective of this study was to describe the dentofacial and soft tissue pattern of Indo-Aryans and to compare it with accepted standards for Caucasians and other North Indian population groups. Lateral cephalometric radiographs of 30 females with pleasing profile and good occlusion, aged 16-21 years, were used. A computer aided cephalometric analysis was performed and the basic descriptive statistics for the various cephalometric variables were obtained. Indo Aryans have shown a mild convex Dental Pattern as compared to Caucasians but similar to North Indians. Their soft tissue pattern is characterised by increased thickness of upper lip and a thin lower lip.

Abstract
A 42-month experience with 100 patients with fatal head injuries was analyzed to identify areas of organ procurement failure. Thirty-six patients were ineligible for organ donation. Reasons for exclusion included advanced age (7), sepsis (16), hepatitis (1), systemic illnesses (3), and HIV infection or risk (9). Resuscitation failure (17 patients) and late deaths from failed support (16 patients) left 31 potential donors. Of the 30 families asked to donate, 17 consented (56.7%). Annual consent rates were 25%, 71%, 75%, and 67%. Efforts to improve organ procurement should focus on resuscitation and physiologic support of potential donors. To assess the impact of HIV infection or risk on organ procurement, a 3-year experience of the regional transplantation center (RTP) was reviewed. Of 1,714 referrals to the RTP from 102 hospitals, 1,120 were from trauma centers. The incidence of rejection because of HIV risk or infection was significantly higher in the trauma center group than in the group from non-trauma centers, 17.2% versus 10.2% (p less than 0.004). A similar difference was noted between metropolitan and suburban hospitals (p less than 0.0001). Hepatitis risk was comparable, 3.9% vs. 3.2%. The risk of HIV infection is emerging as a factor limiting organ donation at urban trauma centers.

Abstract
The use of calcium supplementation for the management of primary postmenopausal osteoporosis (PPMO) has increased significantly in the past few years. A review of the published data does not support calcium megadosing during postmenopause. Controlled studies showed no significant effect of calcium intake on mineral density of trabecular bone and a slight effect on cortical bone. Since PPMO is predominantly due to demineralization of trabecular bone, there is no justification for calcium megadosing in postmenopausal women. Soft tissue calcification is a serious risk factor during calcium megadosing under certain conditions. A total dietary program emphasizing magnesium instead of calcium for the management of PPMO takes into account the available data on the effects of magnesium, life-style and dietary habits on bone integrity and PPMO. When this dietary program was tested on 19 postmenopausal women on hormonal replacement therapy who were compared to 7 control postmenopausal women, a significant increase in mineral bone density of the calcaneous bone (BMD) was observed within one year. Fifteen of the 19 women had had BMD below the spine fracture threshold before treatment; within one year, only 7 of them still had BMD values below that threshold.

Abstract
We report our experience with nine adult patients (six females, three males) with Caroli's syndrome. Most of these patients were young (mean age 27.0 yr), and had presented at a mean interval of 12.1 yr after the onset of symptoms. Recurrent abdominal pain was the most common symptom, present in eight of nine patients. Mild jaundice (serum bilirubin 1.8-4.2 mg/dl) and raised serum alkaline phosphatase (18-36 King-Armstrong units) were the only other significant findings. Ultrasound proved to be a good screening test. However, the diagnosis was confirmed on cholangiography. Six of nine patients had associated extrahepatic biliary cysts (type IVa). The operative management was directed mainly at excising the extrahepatic cysts and draining the biliary tree, and was met with satisfactory results.

Abstract
Spontaneous choledochoduodenal fistula is a rare complication of peptic ulcer disease, the surgical therapy of which is generally directed towards the ulcer disease itself, in the form of vagotomy with antrectomy or gastrojejunostomy. The case reported herein is of a 40 year old man who presented with a spontaneous choledochoduodenal fistula which was successfully treated by a truncal vagotomy and posterior retrocolic gastrojejunostomy. Such procedures as cholecystectomy, common bile duct exploration and bilio-enteric reconstruction, should only be performed in the case of a biliary stricture, which occurs rarely.
