Laparoscopic cholecystectomy: review of 1430 cases in Cure International Hospital, Kabul, Afghanistan.

BACKGROUND: Laparoscopic cholecystectomy (LC) is the gold standard for the treatment of cholelithiasis in most countries of the world. The objective of this study was to evaluate the outcomes of LC in the surgery department of Cure International Hospital, Kabul, Afghanistan. METHODS: A retrospective study was conducted on 1430 LC cases performed by the general surgery department of Cure International Hospital. Data was collected from patient files and the operation theatre registry for whom LC was performed during January 2008 through December, 2019. RESULTS: Mean age was 45.77 ± 13.45 years (14-90 years), with male/female ratio of 1:4.7. One third (33%) had comorbidities. Most of patients (~ 97%) were classified as ASA grade I and II. Of all patients, 26.8% of males and 13.2% of females had gallbladder inflammation (OR = 2.203, 95% CI 1.56-2.61, P = 0.000). Overall mean duration of anesthesia was 75 ± 25.6 min. The conversion rate to OC was 4.6% (N = 66), most commonly dense adhesions at Callot's triangle (3.8%). The intraoperative complication rate was 17.5% (N = 249), where bile/stone spillage was the most common indication (N = 235, 16.4%). Immediate postoperative complication rate was 2.4% (N = 35). Average length of stay (ALOS) after LC was 2.23 ± 1.43 days (1-19 days). CONCLUSION: This study shows that elective LC can be performed safely in Afghanistan with comparable outcomes in terms of complications, conversion rates, and ALOS to other countries of the region and the world. Proper case selection and careful preoperative evaluation and management can decrease further conversion, intra- and postoperative complications.

A Novel Homozygous c.800C>G Substitution in GP1BA Exon 2 in a Kuwaiti Family with Bernard-Soulier Syndrome.

BACKGROUND: Bernard-Soulier syndrome (BSS) is a congenital bleeding disorder characterised by thrombocytopenia, giant platelets and decreased platelet adhesion resulting from genetic alterations of the glycoprotein (GP) Ib/IX/V complex. OBJECTIVES: Three sisters with a lifelong bleeding history and a provisional diagnosis of BSS were referred for further characterisation of their bleeding diathesis. The siblings' symptoms varied in severity from skin and gum bleeding to menorrhagia associated with iron-deficiency anaemia requiring regular transfusion of red cells and platelets. The parents were consanguineous but did not demonstrate any bleeding disorder. METHODS: The family were investigated using standard haematological techniques, platelet aggregometry, platelet membrane GP analysis and DNA sequencing of the genes encoding the GPIb/IX complex. RESULTS: All 3 sisters had thrombocytopenia and giant platelets. Platelet aggregation and flow cytometry studies confirmed the lack of aggregation with ristocetin and a markedly reduced GPIb/IX surface expression. Molecular analysis demonstrated a novel homozygous c.800C>G substitution in GP1BA exon 2 leading to a serine 267 Ter stop codon in all 3 siblings. CONCLUSIONS: A novel, nonsense mutation was identified as the cause of the bleeding disorder in this family. This is the first reported BSS mutation identified in a family from Kuwait.

Clinical phenotype, laboratory features and genotype of 35 patients with heritable dysfibrinogenaemia.

Heritable dysfibrinogenaemia (HD) is a rare qualitative disorder of fibrinogen (FGN). To better describe the clinical, laboratory and genotypic spectrum of HD, we evaluated 35 subjects identified at two UK centres using laboratory criteria. 12/35(34%) subjects with HD experienced bleeding (bleeding score >1 at any site), 3/35(9%) thrombosis and 20/35(57%) were asymptomatic. Amongst subjects with bleeding, symptoms were typically mild, at one anatomical site and seldom occurred after invasive procedures. All subject showed dry clot weight within or above laboratory reference interval (median 3·2 g/l; range 1·9-5·1), reduced Clauss fibrinogen (median 0·52 g/l; range 0·21-1·3), and prolonged thrombin (median 30·7 s; range 21·3-45·7) and reptilase (median 42·0 s; range 20·0-68·0) times. In all subjects, the prothrombin time ratio (PTR), determined by Sysmex CA-1500 coagulometer and Innovin activator, was abnormal (median 1·42; range 1·22-1·61). The activated partial thromboplastin time ratio and PTR with other coagulometers and activators were comparatively insensitive to HD. All subjects with HD harboured heterozygous candidate nucleotide variations within known hotspots in the FGN genes. The HD variants identified in this cross-sectional study seldom have significant clinical manifestations and show similar laboratory features irrespective of genotype. Selection of coagulometer and PT activator may markedly affect the detection of new HD cases using coagulation screening tests.

Disruption of AP3B1 by a chromosome 5 inversion: a new disease mechanism in Hermansky-Pudlak syndrome type 2.

BACKGROUND: Hermansky-Pudlak syndrome 2 (HPS2; OMIM #608233) is a rare, autosomal recessive disorder caused by loss-of-function genetic variations affecting AP3B1, which encodes the ß3A subunit of the adaptor-related protein complex 3 (AP3). Phenotypic characteristics include reduced pigmentation, absent platelet dense granule secretion, neutropenia and reduced cytotoxic T lymphocyte (CTL) and natural killer (NK) cell function. To date HPS2 has been associated with non-synonymous, stop-gain or deletion-insertion nucleotide variations within the coding region of AP3B1. CASE PRESENTATION: We describe a consanguineous female infant with reduced pigmentation, neutropenia and recurrent infections. Platelets displayed reduced aggregation and absent ATP secretion in response to collagen and ADP, indicating a platelet dense granule defect. There was increased basal surface expression of CD107a (lysosome-associated membrane protein 1(LAMP-1)) on NK cells and CTLs from the study subject and a smaller increase in the percentage of CD107a positive cells after stimulation compared to most healthy controls. Immunoblotting of protein extracts from EBV-transformed lymphoblasts from the index case showed absent expression of full-length AP-3 ß3A subunit protein, confirming a phenotypic diagnosis of HPS2.The index case displayed a homozygous pericentric inv(5)(p15.1q14.1), which was also detected as a heterozygous defect in both parents of the index case. No loss of genetic material was demonstrated by microarray comparative genome hybridisation at 60kb resolution. Fluorescence in-situ hybridisation using the 189.6kb probe RP11-422I12, which maps to 5q14.1, demonstrated dual hybridisation to both 5q14.1 and 5p15.1 regions of the inverted Chr5. The RP11-422I12 probe maps from intron 1 to intron 16 of AP3B1, thus localising the 5q inversion breakpoint to within AP3B1. The probe RP11-211K15, which corresponds to an intergenic region on 5p also showed dual hybridisation, enabling localisation of the 5p inversion breakpoint. CONCLUSION: This case report extends the phenotypic description of the very rare disorder HPS2. Our demonstration of a homozygous Chr5 inversion predicted to disrupt AP3B1 gene provides a novel pathogenic mechanism for this disorder.

Low serum iron levels are associated with elevated plasma levels of coagulation factor VIII and pulmonary emboli/deep venous thromboses in replicate cohorts of patients with hereditary haemorrhagic telangiectasia.

BACKGROUND: Elevated plasma levels of coagulation factor VIII are a strong risk factor for pulmonary emboli and deep venous thromboses. OBJECTIVES: To identify reversible biomarkers associated with high factor VIII and assess potential significance in a specific at-risk population. PATIENTS/METHODS: 609 patients with hereditary haemorrhagic telangiectasia were recruited prospectively in two separate series at a single centre. Associations between log-transformed factor VIII measured 6 months from any known thrombosis/illness, and patient-specific variables including markers of inflammation and iron deficiency, were assessed in stepwise multiple regression analyses. Age-specific incidence rates of radiologically proven pulmonary emboli/deep venous thromboses were calculated, and logistic regression analyses performed. RESULTS: In each series, there was an inverse association between factor VIII and serum iron that persisted after adjustment for age, inflammation and/or von Willebrand factor. Iron response elements within untranslated regions of factor VIII transcripts provide potential mechanisms for the association. Low serum iron levels were also associated with venous thromboemboli (VTE): the age-adjusted OR of 0.91 (95% CI 0.86 to 0.97) per 1 µmol/litre increase in serum iron implied a 2.5-fold increase in VTE risk for a serum iron of 6 µmol/litre compared with the mid-normal range (17 µmol/litre). The association appeared to depend on factor VIII, as once adjusted for factor VIII, the association between VTE and iron was no longer evident. CONCLUSIONS: In this population, low serum iron levels attributed to inadequate replacement of haemorrhagic iron losses are associated with elevated plasma levels of coagulation factor VIII and venous thromboembolic risk. Potential implications for other clinical populations are discussed.

Monitoring heparin anticoagulation in the acute phase response.

The anticoagulant effect of unfractionated heparin (UFH) is monitored using the activated partial thromboplastin time (APTT). An APTT of 1.5-2.5 times the control is usually taken as the therapeutic range and assumed to reflect an anti-activated factor X (anti-Xa) level of 0.35-0.7 u/ml. However, in some cases, despite administration of sufficient heparin to achieve a therapeutic anti-Xa assay level, the APTT remains sub-therapeutic. This 'apparent heparin resistance' is commonly due to high levels of factor VIII (FVIII). In these situations, the anti-Xa is usually preferred for monitoring in order to avoid, what might be, dangerously high levels of heparin. We hypothesized that at high FVIII levels, the heparin resistance encountered may be genuine rather than apparent and that higher doses of heparin may indeed be needed for an equivalent anticoagulant effect. The relationship between heparin level, APTT and anticoagulant effect at different FVIII concentrations was determined using thrombelastography and the thrombin generation assay. Thromboelastographic and thrombin generation parameters concurred with APTT, demonstrating a genuine heparin resistance in the presence of high FVIII levels. This suggests that APTT may be a more accurate measure of anticoagulant effect in vivo than anti-Xa.

Should laparoscopic cholecystectomy be practiced in the developing world?: the experience of the first training program in Afghanistan.

OBJECTIVE: We address the controversial issue of whether or not it is wise to perform and train laparoscopic cholecystectomy (LC) in a developing nation by reviewing the results of the first large series done in Afghanistan. Afghanistan has been devastated by 3 decades of war leaving it with deficiencies in training programs, medical technologies, and overall medical infrastructure that are among the worst in the developing world. METHODS: We retrospectively reviewed 137 consecutive cholecystectomies, 102 laparoscopic and 35 open, performed by 4 senior and 3 junior surgeons trained at our hospital in Kabul from July 2005 until February 2008. Deaths, complications, conversion rate, operative time, and hospital length of stay were compared. RESULTS: Unrecognized major operative injuries occurred in 4 LC patients, 3 bile leaks, and 1 duodenal perforation, although there were no such injuries in the open cholecystectomy group. Complication rates were much higher for patients operated on for acute cholecystitis for both surgeon groups. Even though junior surgeons converted to open cholecystectomy more frequently than senior surgeons, they had a higher major complication rate. Hospital length of stay was 28% shorter for the laparoscopic group. CONCLUSIONS: The high rate of major unrecognized intraoperative complications during LC in our series underscores the difficulties inherent in performing and training LC in developing nations. Practical changes are suggested to make LC more efficient and safer in a developing world hospital.

Pharmaceutical risk-sharing agreements.

Increased spending on pharmaceuticals continues to foster debate over healthcare policy. The increasing costs of bringing products to the market, as well as increased utilization of pharmaceuticals contribute to increased pharmaceutical expenditure; however, appropriate pharmaceutical use can, in certain cases, reduce overall healthcare costs. Nevertheless, the perception of high drug prices still puts pressure on pharmaceutical companies to build confidence in the proposition that their products are worth the additional expense. One potential approach to building this confidence, and maintaining investment incentives, is for the pharmaceutical company to share the risk of a situation in which there is uncertainty about whether the product is effective for the consumer and payer. Such risk-sharing arrangements for pharmaceuticals, like warranties, can be used to signal high quality when product quality is not fully observable. While there may be difficulties in devising such schemes for every product, such risk-sharing plans may become a staple feature of the market in the future.

A structural basis for the amphiphilic character of alginates - Implications for membrane fouling.

Ostensibly hydrophilic alginates are known to foul hydrophobic membranes, under various conditions. Here, controlled experiments have been conducted at high and low pH on the fouling of a polypropylene membrane by alginate and the results suggest that the observed fouling is due to an intrinsic property of the alginate. Thus quantum chemical calculations on the M and G monomers of alginate reveal that M adopts an equilibrium geometry that is hydrophilic on one face and hydrophobic on the other, i.e. is potentially amphiphilic. Molecular dynamics simulations on short alginate chains of different sequences interacting with a modelled polypropylene surface, show that this characteristic is carried over to the polymer and results in hydrophobic patches along the chain that facilitate attractive interactions with the polypropylene surface. This concept is buttressed by an analysis of the binding characteristics of a previously reported X-ray structure of the mannuronan C-5 epimerase AlgE4 enzyme.

Antithrombin Nagasaki (Ser 116 to Pro): a rare antithrombin variant with abnormal heparin binding presenting during pregnancy.

Quantitative antithrombin deficiency constitutes an important risk factor for venous thromboembolism, stillbirth, and other complications of pregnancy. Studies suggest, however, that individuals heterozygous for missense mutations involving the heparin-binding site of antithrombin do not have a significantly increased thrombotic risk. Owing to the rarity of such mutations, it remains unclear whether any specific heparin-binding site defects might be associated with thrombotic potential. We report here the case of a pregnant woman with an exceptionally rare Type II heparin-binding site antithrombin variant. This case highlights the difficult issues that are associated with the management of Type II antithrombin deficiency during pregnancy.

Confirmatory Factor Analysis and Multiple Linear Regression of the Neck Disability Index: Assessment If Subscales Are Equally Relevant in Whiplash and Nonspecific Neck Pain.

OBJECTIVE: Because of previously published recommendations to modify the Neck Disability Index (NDI), we evaluated the responsiveness and dimensionality of the NDI within a population of adult whiplash-injured subjects. The purpose of the present study was to evaluate the responsiveness and dimensionality of the NDI within a population of adult whiplash-injured subjects. METHODS: Subjects who had sustained whiplash injuries of grade 2 or higher completed an NDI questionnaire. There were 123 subjects (55% female, of which 36% had recovered and 64% had chronic symptoms. NDI subscales were analyzed using confirmatory factor analysis, considering only the subscales and, secondly, using sex as an 11th variable. The subscales were also tested with multiple linear regression modeling using the total score as a target variable. RESULTS: When considering only the 10 NDI subscales, only a single factor emerged, with an eigenvalue of 5.4, explaining 53.7% of the total variance. Strong correlation (> .55) (P < .0001) between all variables was found. Multiple linear regression modeling revealed high internal consistency with all coefficients reaching significance (P < .0001). The 4 NDI subscales exerting the greatest effect were, in decreasing order, Sleeping, Lifting, Headaches, and Pain Intensity. CONCLUSION: A 2-factor model of the NDI is not justified based on our results, and in this population of whiplash subjects, the NDI was unidimensional, demonstrating high internal consistency and supporting the original validation study of Vernon and Mior.

Dietary supplement use and nosebleeds in hereditary haemorrhagic telangiectasia - an observational study.

Understanding potential provocations of haemorrhage is important in a range of clinical settings, and particularly for people with abnormal vasculature. Patients with hereditary haemorrhagic telangiectasia (HHT) can report haemorrhage from nasal telangiectasia in real time, and suggested dietary factors may precipitate nosebleeds. To examine further, nosebleed severity, dietary supplement use, and blood indices were evaluated in an unselected group of 50 HHT patients recruited from a specialist UK service. Using the validated Epistaxis Severity Score, nosebleed severity ranged from 0 to 9.1 out of 10 (median 3.9). Using a Food Frequency Questionnaire, 24/50 (48%) participants reported use of dietary supplements in the previous year. A third (18/50; 36%) had used self prescribed, non-iron containing dietary supplements, ingesting between 1 and 3 different supplements each day. Eight (16%) used fish oils. Despite having more severe epistaxis (p = 0.012), the 12 iron supplement users had higher serum iron concentrations, and were able to maintain their red blood cell indices. In contrast, there was no evident benefit for the participants using non iron supplements. Furthermore, platelet counts and serum fibrinogen tended to be lower in fish oil/supplement users, and one fish oil user demonstrated reduced in vitro platelet aggregation. In conclusion, in this small study, a third of HHT patients used non-iron dietary supplements, and one in six ingested fish oils, unaware of their known anti-platelet activity. The scale of use, and potential of these "natural health supplements" to exacerbate nosebleeds has not been appreciated previously in HHT.

Amount of H antigen expressed on circulating von Willebrand factor is modified by ABO blood group genotype and is a major determinant of plasma von Willebrand factor antigen levels.

To investigate whether the effect of ABO blood group on plasma von Willebrand factor (vWF) levels is mediated by the ABH antigenic determinants carried on N-linked glycans of vWF, we studied 158 group A and group O healthy volunteers. vWF antigen (vWF:Ag) and factor VIII antigen (FVIII:Ag) levels were highest in A(1)A(1) individuals and higher in A(1)O(1) than in A(2)O(1) or O(1)O(1) individuals. Plasma A transferase activity and the amount of A antigen expressed per unit vWF (AvWF) were significantly higher in A(1)A(1) than in A(1)O(1) individuals and higher in A(1)O(1) than in A(2)O(1) individuals. AvWF was correlated strongly with plasma levels of A transferase activity. Thus, we have clearly demonstrated a direct relationship between ABO genotype, A transferase expression, and the amount of A antigen expressed on circulating vWF. H antigen expression per unit vWF (HvWF) was highest in group O individuals. Among group A individuals, the pattern of HvWF expression was A(2)O(1)>A(1)O(1)>A(1)A(1). In group O and group A(2)O(1) individuals, HvWF was inversely correlated with plasma vWF levels. In contrast, among group A(1)A(1) and A(1)O(1) individuals, there was no relationship between AvWF and plasma vWF levels. These findings suggest that it is H antigen expression that mediates the ABO effect on plasma vWF concentration.

Low-density lipoprotein receptor-related protein polymorphisms in patients with elevated factor VIII coagulant activity and venous thrombosis.

Elevated factor VIII coagulant activity (FVIII:C) levels (>150 IU/dl) represent a prevalent independent risk factor for venous thromboembolism (VTE). Low-density lipoprotein receptor-related protein (LRP) is involved in factor VIII clearance in vivo, and elevated FVIII:C was a feature of the LRP knockout mouse model. Three coding polymorphisms of LRP1 (exon 3, C766T; exon 14, A217V; and exon 39, D2080N), together with an insertion/deletion polymorphism within the first intron of lipoprotein receptor-associated protein (LRPAP1), have been identified. In addition, LRP1 2080D was recently reported to be associated with increased plasma FVIII:C levels in normal individuals. In this study, we investigated the role of these four polymorphisms in patients with objectively confirmed VTE and elevated FVIII:C levels. In our control group, genotype distributions were consistent with previous reports. Neither the allele frequencies nor genotype distributions at LRP1 A217V, LRP1 D2080N and LRPAP1 intron 1 were significantly different between the elevated FVIII:C and control groups. In contrast to previous reports, we found no effect of LRP1 D2080N genotype on plasma FVIII:C levels in normal individuals. More importantly, prevalence of the LRP1 2080D allele was not increased in the group of patients with high FVIII:C and VTE. We conclude that LRP1 and LRPAP1 polymorphisms are not responsible for high FVIII:C levels in patients with VTE.

Ischaemic strokes in patients with pulmonary arteriovenous malformations and hereditary hemorrhagic telangiectasia: associations with iron deficiency and platelets.

BACKGROUND: Pulmonary first pass filtration of particles marginally exceeding ∼7 µm (the size of a red blood cell) is used routinely in diagnostics, and allows cellular aggregates forming or entering the circulation in the preceding cardiac cycle to lodge safely in pulmonary capillaries/arterioles. Pulmonary arteriovenous malformations compromise capillary bed filtration, and are commonly associated with ischaemic stroke. Cohorts with CT-scan evident malformations associated with the highest contrast echocardiographic shunt grades are known to be at higher stroke risk. Our goal was to identify within this broad grouping, which patients were at higher risk of stroke. METHODOLOGY: 497 consecutive patients with CT-proven pulmonary arteriovenous malformations due to hereditary haemorrhagic telangiectasia were studied. Relationships with radiologically-confirmed clinical ischaemic stroke were examined using logistic regression, receiver operating characteristic analyses, and platelet studies. PRINCIPAL FINDINGS: Sixty-one individuals (12.3%) had acute, non-iatrogenic ischaemic clinical strokes at a median age of 52 (IQR 41-63) years. In crude and age-adjusted logistic regression, stroke risk was associated not with venous thromboemboli or conventional neurovascular risk factors, but with low serum iron (adjusted odds ratio 0.96 [95% confidence intervals 0.92, 1.00]), and more weakly with low oxygen saturations reflecting a larger right-to-left shunt (adjusted OR 0.96 [0.92, 1.01]). For the same pulmonary arteriovenous malformations, the stroke risk would approximately double with serum iron 6 µmol/L compared to mid-normal range (7-27 µmol/L). Platelet studies confirmed overlooked data that iron deficiency is associated with exuberant platelet aggregation to serotonin (5HT), correcting following iron treatment. By MANOVA, adjusting for participant and 5HT, iron or ferritin explained 14% of the variance in log-transformed aggregation-rate (p = 0.039/p = 0.021). SIGNIFICANCE: These data suggest that patients with compromised pulmonary capillary filtration due to pulmonary arteriovenous malformations are at increased risk of ischaemic stroke if they are iron deficient, and that mechanisms are likely to include enhanced aggregation of circulating platelets.

Extrapulmonary tuberculosis in Kabul, Afghanistan: a hospital-based retrospective review.

OBJECTIVES: The purpose of this study is to amplify the knowledge base of the epidemiology, symptoms, and signs of extrapulmonary tuberculosis (EPTB) in Afghanistan. METHODS: This is a retrospective review of EPTB diagnosed at CURE International Hospital and CURE Family Health Center (FHC) in Kabul, Afghanistan during a recent 20-month period. RESULTS: One hundred eighteen cases were identified from patients presenting to the hospital and FHC. This group represents the spectrum of EPTB seen at a single referral center in Kabul. The ratio of females to males was 2.03:1. Lymph node tuberculosis comprised the greatest number of EPTB cases (37.3%, n=44). The central nervous system was the next most frequent site of EPTB involvement (20.3%, n=24), followed in descending order by skeletal, pleural, abdominal, cutaneous, genitourinary, pericardial, miliary, and breast tuberculosis. CONCLUSIONS: The 2:1 ratio of female to male EPTB cases coincides with the unusual epidemiologic pattern seen in smear-positive pulmonary TB in Afghanistan. As the first epidemiological report of EPTB from Afghanistan, this study illustrates the varied presentations of EPTB that should be known by healthcare workers throughout the country.

Endothelial cell processing and alternatively spliced transcripts of factor VIII: potential implications for coagulation cascades and pulmonary hypertension.

BACKGROUND: Coagulation factor VIII (FVIII) deficiency leads to haemophilia A. Conversely, elevated plasma levels are a strong predictor of recurrent venous thromboemboli and pulmonary hypertension phenotypes in which in situ thromboses are implicated. Extrahepatic sources of plasma FVIII are implicated, but have remained elusive. METHODOLOGY/PRINCIPAL FINDINGS: Immunohistochemistry of normal human lung tissue, and confocal microscopy, flow cytometry, and ELISA quantification of conditioned media from normal primary endothelial cells were used to examine endothelial expression of FVIII and coexpression with von Willebrand Factor (vWF), which protects secreted FVIII heavy chain from rapid proteloysis. FVIII transcripts predicted from database mining were identified by RT-PCR and sequencing. FVIII mAb-reactive material was demonstrated in CD31+ endothelial cells in normal human lung tissue, and in primary pulmonary artery, pulmonary microvascular, and dermal microvascular endothelial cells. In pulmonary endothelial cells, this protein occasionally colocalized with vWF, centered on Weibel Palade bodies. Pulmonary artery and pulmonary microvascular endothelial cells secreted low levels of FVIII and vWF to conditioned media, and demonstrated cell surface expression of FVIII and vWF Ab-reacting proteins compared to an isotype control. Four endothelial splice isoforms were identified. Two utilize transcription start sites in alternate 5' exons within the int22h-1 repeat responsible for intron 22 inversions in 40% of severe haemophiliacs. A reciprocal relationship between the presence of short isoforms and full-length FVIII transcript suggested potential splice-switching mechanisms. CONCLUSIONS/SIGNIFICANCE: The pulmonary endothelium is confirmed as a site of FVIII secretion, with evidence of synthesis, cell surface expression, and coexpression with vWF. There is complex alternate transcription initiation from the FVIII gene. These findings provide a framework for future research on the regulation and perturbation of FVIII synthesis, and of potential relevance to haemophilia, thromboses, and pulmonary hypertensive states.

Management of biliary Ascaris lumbricoides in Kabul, Afghanistan: crossroads of advancing technology.

The case is presented of the successful removal of a dead Ascaris lumbricoides from the right hepatic duct of a middle aged woman from a rural province in Afghanistan. The case was started laparoscopically, but converted to an open procedure because of difficulty identifying the anatomic landmarks required to safely perform laparoscopic cholecystectomy. After worm removal, the common bile duct (CBD) was reconstructed with a Roux-en-Y hepaticojejunostomy. The patient was discharged on postoperative day 7 and was doing well when seen in the outpatient clinic 2 weeks later.
