RESUMO
BACKGROUND: Diets that include fruits and vegetables have been suggested as one way to reduce the risk of developing colorectal cancer (CRC); however, the association between consuming fruits and vegetables and CRC risk is not clear. The objective of the present study is to compare fruit and vegetable intake between 2 groups of Jordanians and further investigate this possible relationship. METHODS: A history of fruit and vegetable consumption was obtained from 220 people with CRC and 281 healthy controls, all of whom were from Jordan. Both groups were matched for age, sex, occupation, and marital status. Fruit and vegetable consumption was quantified for the previous 12 months in both groups. RESULTS: Total vegetable intake was associated with the risk of developing CRC. Consuming 5 servings of vegetables a day decreased the risk of developing CRC when compared with no more than 1 serving a day (odds ratio [OR] = 0.23; 95% confidence interval [CI]: 0.55-0.97). A significant direct relationship between CRC risk and consuming cauliflower and cabbage was found; however, no association was found for raw or cooked leafy vegetable and other vegetable types. Consuming several types of fruits also revealed no association with risk of CRC, although an increased intake of dates and figs was associated with a reduced risk of developing CRC. The ORs for the highest intake of servings compared with the lowest intake were 0.48 (95% CI: 0.27-0.87; P = .004) for dates and 0.604 (95% CI: 0.35-1.06; P = .003) for figs. CONCLUSIONS: Consuming fruits and vegetables did not significantly correlate with a lowered incidence of CRC. However, a trend of protection was detected for several types of fruits and vegetables.

Introduction: Objective: several dietary and non-dietary factors and genetic predisposition may play an important role in gastric carcinogenesis. The findings about associations between micronutrients and gastric cancer (GC) is still inconsistent. This study aimed to investigate the effect of dietary micronutrients on gastric cancer risk. Methods: a case-control study comprised of 173 GC (107 males: 66 females) patients and 313 (190 males: 123 females) population-based controls matched for age, occupation, and marital status. Demographics, medical history, physical activity, and nutrient intake information were collected using reliable interview-based questionnaires. Information on dietary micronutrient intake was collected from the participants using a validated food frequency questionnaire (FFQ). Multinomial logistic regression was used to calculate Odds ratios (ORs) and their corresponding 95 % confidence intervals (CIs) and evaluate associations between dietary micronutrients and GC risk. Results: GC was inversely associated with the consumption of vitamin A, beta-carotene, vitamins D, E, K, B2, B3, B6, B12, and C, folate, chromium, iodine, and selenium. Additionally, a protective effect was observed for consumption of calcium, copper, iron, magnesium, phosphate, sodium, and zinc. In almost all the micronutrients, the second tertile showed a more pronounced reduction in GC risk as compared to the first tertile. Conclusions: our data support favorable effects of dietary consumption of some vitamins and minerals against GC risk.
Introducción: Objetivo: varios factores dietéticos y no dietéticos y predisposiciones genéticas pueden jugar un papel importante en la carcinogénesis gástrica. Los hallazgos sobre las asociaciones entre los micronutrientes y el cáncer gástrico (CG) aún son inconsistentes. Métodos: este estudio tuvo como objetivo investigar el efecto de los micronutrientes sobre el riesgo de cáncer gástrico. Métodos: Un estudio de casos y controles comprendió 173 pacientes con GC (107 hombres: 66 mujeres) y 313 (190 hombres: 123 mujeres) controles basados en la población emparejados por edad, ocupación y estado civil. La información demográfica, el historial médico, la actividad física y la ingesta de nutrientes se recopilaron mediante cuestionarios confiables basados en entrevistas. La información sobre la ingesta de micronutrientes en la dieta se recopiló de los participantes mediante un cuestionario de frecuencia de alimentos (FFQ) validado. Se utilizó la regresión logística multinomial para calcular las razones de probabilidad (OR) y sus correspondientes intervalos de confianza (IC) del 95 % y evaluar las asociaciones entre los micronutrientes de la dieta y el riesgo de GC. Resultados: la GC se asoció inversamente con el consumo de vitamina A, betacaroteno, vitaminas D, E, K, B2, B3, B6, B12 y C, folatos, cromo, yodo y selenio. Adicionalmente, se observó un efecto protector para el consumo de calcio, cobre, hierro, magnesio, fosfato, sodio y zinc. En casi todos los micronutrientes, el tercer tercil mostró una reducción más pronunciada del riesgo de CG en comparación con el primer tercil en hombres. Por el contrario, el segundo tercil exhibió un nivel de protección significativamente marcado en comparación con el primer tercil en mujeres. Conclusiones: nuestros datos respaldan los efectos favorables del consumo dietético de algunas vitaminas y minerales para el riesgo de desarrollar cáncer gástrico.

Countries experiencing a significant shift toward Western lifestyle are facing an increased risk of gastric cancer (GC). While many studies have explored the link between diet and GC, the role of meat and dairy consumption remains uncertain. To delve deeper into this association, we conducted a case-control study in Jordan involving 173 GC cases and 314 controls, matched by age and marital status. Using a validated food frequency questionnaire, we assessed the intake of different dairy and meat products. The adjusted odds ratios and corresponding 95% confidence intervals indicated a strong correlation between high intake of red meat, milk, and buttermilk and GC. Our multinomial logistic regression analysis revealed that daily consumption of red meat (≥1 serving/day; OR, 3.34 [95% CI 1.85-6.03, p value of trend <.001], ≥1 serving/day) and weekly intake of milk (2-3 servings/week; OR, 2.04 [95% CI 1.14-3.64, p value of trend = .041]) and buttermilk (2-3 servings/week; OR, 2.07 [95% CI 1.12-3.83, p value of trend = .018], per 2-3 servings/week) were significantly associated with an increased risk of GC. Furthermore, consuming cooked eggs daily (OR = 2.44, 95% CI 1.24-4.79, p trend <.001) or weekly (OR, 3.34, 95% CI 1.58-7.10, p value of trend <.001) was also associated with an increased risk of GC. These findings highlight the potential health risks associated with excessive meat and some dairy products consumption and suggest that a balanced intake of these products, along with eggs, may help prevent GC.
RESUMO
OBJECTIVES: Pancreatic cancer (PC) has been related directly to many risk factors; however, diet is considered one of the most modifiable risk factors. This study is designed to observe the associations between the intake of macromicronutrients and the risk of pancreatic cancer in a Jordanian population. METHODS: A case-control study included 100 patients with the incident and histologically confirmed PC and 309 control subjects frequency-matched on age, educational level, occupation, and marital status. Face-to-face interview was used to collect the study's sociodemographic, physical activity, and dietary information. Intakes of macronutrients and micronutrients were assessed by a validated food-frequency questionnaire. Multinomial logistic regression was used to calculate odds ratios and confidence intervals. RESULTS: The patients reported higher consumption of almost all the macromicronutrients and micronutrients as compared with control subjects. The highest tertile of dietary intake of carbohydrates, sugars, fats, saturated fats, monounsaturated fats, trans fats, cholesterol, and vitamin B3 was positively associated with PC risk (Ptrend < 0.05). However, dietary intakes of polyunsaturated fats, omega-3, and some vitamins and minerals were not associated (Ptrend > 0.05) with the risk of PC. CONCLUSIONS: Our findings support the positive role of proteins, carbohydrates, sugars, fats, saturated fats, monounsaturated fats, trans fats, and cholesterol on pancreatic carcinogenesis.

Diet is an important modifiable lifestyle factor, but epidemiological studies evaluating the association between dietary patterns and pancreatic cancer (PC) have reported inconsistent findings. This study aimed to evaluate the impact of several dietary choices on the risk of PC among newly diagnosed Jordanian patients. A case-control study was conducted at major teaching and general hospitals, including a Jordanian oncology center. The study included 101 patients with incident pancreatic cancer and 314 controls. Data was collected using interview-based questionnaires. Dietary intake was estimated using a validated Arabic and reproducible food-frequency questionnaire. Dietary patterns were derived using Principal Component Analysis. Multinomial logistic regression was used to estimate the association between dietary patterns and PC. Four dietary patterns were identified. The "Traditional" dietary pattern, which presented a diet rich in fresh fruits, vegetables, milk, yogurt, and lentils, was associated with a significant decrease in the odds of PC (OR = 0.42, 95% CI = 0.21-0.84) for the third quartile compared to first one. The "High-fruit" dietary pattern, which was loaded with strawberry, melon, watermelon, and other fruits, significantly reduced the odds of PC (OR = 0.38, 95% CI = 0.19-0.75) for the second quartile compared to the first one. The "Soup" dietary pattern was mainly composed of vermicelli soup, vegetable soup, lentil soup, and mushroom soup, which decreased the odds of PC (OR = 0.18, 95% CI = 0.07-0.38). There was no relation between PC and the "Western" dietary pattern, loaded with beer, wine, roasted lamb, meat, chicken sandwich, beefsteak, and fried fish. The "Traditional," "High-fruit," and "Soup" dietary patterns were associated with reduced risk of PC among Jordanians.

Studies on the association between gastric cancer (GC) and the intake of nutrients in Jordan are very limited, while findings from other reports on the intake of energy and macronutrients are controversial. This study aimed to examine the associations between intake of energy and macronutrients and the risk of GC in a Jordanian population. A case-control study was carried out between March 2015 and August 2018 in four major hospitals, including an oncology center in Jordan. Study participants were 173 cases with incident and histologically confirmed GC and 314 frequency-matched controls. Interview-based questionnaires were used to obtain the study's information. Data on nutrient intake were collected using a validated Arabic food-frequency questionnaire (FFQ). Odds ratios (ORs) and their corresponding 95% confidence intervals (CIs) were calculated through multinomial logistic regression and adjusted for potential confounders, including age, marital status, education, body mass index (BMI), smoking, period of smoking, family history of gastric cancer, history of gastric ulcer, and physical activity. Intakes of total fat, saturated fat, monounsaturated fat, polyunsaturated fat, cholesterol, trans-fat, and omega-6 fatty acids were significantly associated with increased risk of GC. The ORs for the highest versus the lowest tertiles were 6.47 (95% Cl: 3.29-12.77), 2.97 (95% CI: 1.58-5.58), 6.84 (95% CI: 3.46-13.52), 6.19 (95% CI: 3.15-12.17), 3.05 (95% CI: 1.58-5.88), 8.11 (95% CI: 4.20-15.69), and 2.74 (95% CI: 1.47-5.09), respectively. No significant association was found for energy, protein, carbohydrate, sugar, fibers, and omega-3 fatty acids. The findings of this study suggest that high intake of selected types of fats was associated with an increased risk of GC.

Background: Diet pattern is an important modifiable lifestyle factor. However, epidemiological studies show that the association between dietary patterns and gastric cancer (GC) is conflicting. This study aims to assess the impact of several dietary choices on the risk of GC among newly diagnosed Jordanian patients. Methods: A case-control study was conducted at major oncology centers and hospitals in Jordan. Study participants included 172 patients with incident gastric cancer and 314 controls. Data was collected using interview-based questionnaires. Dietary intake was estimated using a validated Arabic and reproducible food-frequency questionnaire (FFQ). Dietary patterns were derived using Principal Component Analysis (PCA). Multinomial logistic regression was used to estimate the association between dietary patterns and GC. Results: Four dietary patterns were itemized; "Mediterranean", "Prudent", "Unhealthy" and "High-fruit" dietary patterns. The "Mediterranean" dietary pattern, which includes a diet rich in fresh fruits, vegetables, milk, yogurt, lentils, and olive oil was associated with a significant decrease in the odds ratio (OR) of GC for the third and fourth quartiles (OR, 0.394 (confidence interval (CI): 0.211-0.736); 0.212 (CI: 0.107-0.419), respectively) after adjusting for age, gender, body mass index, smoking, marital status, total energy intake, education level, and physical activity. While the "Unhealthy" and "Prudent" dietary patterns enhance the risk of developing GC, this risk was insignificant at any quartile. Additionally, the "High-Fruit" dietary pattern shows an insignificant protective effect against the risk of GC. Conclusion: The "Mediterranean" dietary pattern was associated with a reduced risk of GC among Jordanians. However, the other three identified dietary patterns were not significantly associated with the risk of GC.
RESUMO
Gastric cancer (GC) and pancreatic cancer (PC) are the third and seventh most likely cancers to cause death worldwide. We aimed to determine the dietary and lifestyle factors of patients with GC or PC and their associated risk among Jordanians. This case-control study enrolled 587 adults (patients with PC, 101; patients with GC, 172; healthy controls, 314) between March 2015 and August 2018, who were assessed using interview-based personal and physical activity questionnaires. Multivariable logistic regression models were taken as measures for predictors of GC and PC risk. We showed that GC and PC patients had higher pre-diagnosis body-mass indexes, a greater proportion smoked and had a family history of cancer than controls. Furthermore, consumption of two snacks [odds ratios (OR)=0.44, 95% confidence intervals (CI): 0.23~0.85], three snacks (OR=0.04, 95% CI: 0.01~0.23) and no meals eaten outside (OR=0.31, 95% CI: 0.09~0.99) showed a protective effect against GC, and consumption of three snacks (OR=0.08, 95% CI: 0.02~0.40) reduced significantly the risk of PC. These results suggest that bodyweight, physical activity, smoking, and family history of cancer are among factors that affect GC and PC risk among Jordanians.
RESUMO
Colorectal cancer (CRC) is the third most frequently diagnosed cancer worldwide. Leptin and adiponectin are hormones produced by adipose tissues, which exhibit opposing effects on tumor growth. Leptin promotes tumor development and metastasis, whereas adiponectin attenuates this. The aim of the present study was to assess the possible association between leptin and adiponectin [both high molecular weight (HMW) and non-HMW factions] levels with CRC, CRC response to chemotherapy, and to study the relationship between LEPR (rs6588147), ADIPO (rs266729), LEP (rs2167270), and ADIPO (rs822369) polymorphisms and CRC. A total of 32 blood samples collected from CRC patients were analyzed to identify the serum levels of leptin and adiponectin, and the presence of CRC related polymorphisms. A total of 25 healthy subjects were recruited in the control group. Serum levels of leptin and adiponectin were detected using ELISA whereas DNA from patients and controls was amplified and analyzed using PCR-restriction fragment length polymorphism assay. The results showed that the levels of leptin and non-HMW adiponectin were significantly higher in CRC patients compared with the controls (P<0.05). In addition, HMW adiponectin was significantly higher in patients receiving chemotherapy. The association between LEPR (rs6588147), ADIPO (rs266729), LEP (rs2167270) and ADIPO (rs822369) polymorphisms and CRC was not significant (P>0.05). In conclusion, higher leptin and non-HMW adiponectin levels may be associated with increased CRC. Chemotherapy may positively influence the levels of HMW adiponectin. No association between LEPR (rs6588147), ADIPO (rs266729), LEP (rs2167270) and ADIPO (rs822369) polymorphisms with CRC was found.

Background: The effects of consuming fast foods, sweets and beverages on the development of colorectal cancer (CRC) are unclear. The aim of this case-control study was to assess possible associations between the consumption of different fast foods, sweets and beverages and CRC risk in a Jordanian population. Methods: Two hundred and twenty diagnosed CRC cases and 281 controls were enrolled. Diet history was obtained using a validated quantitative questionnaire. Results: Consumption of some types of fast food, and particularly falafel, was associated with an increased risk of developing CRC. Elevated risk was found for potato and corn chips with an AOR of 4.36 (95%CI: 1.24-15.28) for daily consumption and 3.33 (95%CI: 1.00-11.11) for ≥5 servings/week. Consuming 1-2 or >5 servings per week of fried potatoes or 2-3 servings per week of chicken in sandwiches also increased the risk while exposure to fresh tomato juice and hot pepper sauce on a monthly basis appeared to exert a protective effect. Conclusions: Consumption of fried fast food items was significantly linked with an increased risk of developing CRC in Jordan.
RESUMO
BACKGROUND & AIMS: Dietary pattern and lifestyle have been reported to be important risk factors in the development of colorectal cancer (CRC). However, the mechanism of action of dietary factors in CRC disease is unclear. The aim of this study is the examination of several dietary choices and their potential association with the risk of developing CRC. METHODS: Dietary data was collected from 220 subjects who were previously diagnosed with CRC, and 281 control subjects (matched by age, gender, occupation and marital status). The data was collected between January 2010 and December 2012, using interview-based questionnaires. Multivariate logistic regression was used to estimate the relationship between dietary choices and risk of developing colorectal cancer. RESULTS: Factor analysis revealed three major dietary patterns. The first pattern we identified as the "Healthy Pattern", the second was identified as "High Sugar/High Tea Pattern" and the third as "Western Pattern". In the Healthy Pattern group we found a 10.54% variation in food intake, while the intake variation was 11.64% in the Western Pattern. After adjusting for confounding factors, the Western Pattern food choice was found to be significantly associated with an increased risk of developing CRC (OR = 1.88; 95% CI = 1.12-3.16). The results for the Healthy and High-Sugar/High Tea Patterns showed a decrease, but the statistic was not significant for the risk of CRC development. CONCLUSION: The Western Pattern of dietary choice was directly associated with CRC. The association between the dietary food choice in the Healthy and High-Sugar/High Tea Patterns and colorectal cancer needs further study in our Jordanian population.

Dietary components that promote inflammation of the colon have been suggested to be risk factors in the development of colorectal cancer (CRC). The possible link between inflammatory potential of diet and CRC has been investigated in several developed or Western countries. Despite the fact that dietary choices in the Middle East differ markedly from those in the West, results have not been reported from any study conducted in a Middle-Eastern population. We examined the association between dietary inflammatory index (DII) scores and CRC in a case-control study conducted in Jordan. This study included 153 histopathologically confirmed CRC cases and 202 disease-free control subjects' frequency matched on age, sex, and occupation. Data were collected between January 2010 and December 2012, using interviewer-administered questionnaires. DII scores were computed from dietary data reported using a food frequency questionnaire. Logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) adjusted for age, sex, education, physical activity, body mass index, smoking, and family history of CRC. Subjects with higher DII scores were at increased odds of CRC, with the DII being used both as a continuous variable (ORcontinuous = 1.45, 95% CI: 1.13-1.85; 1-unit increase corresponding to ≈20% of its range in the current study) and as a categorical variable (ORtertile 3 vs tertile 1 = 2.13, 95%CI: 1.23-3.72). Our results, based on a Jordanian population, add to the growing literature indicating that a pro-inflammatory diet is associated with increased odds of CRC.

The role of diet in colorectal cancer (CRC) in Jordan has not been studied previously. This study aimed at examining the association between food groups (including grains, fruits, vegetables, milk, and meat and legumes) and CRC risk in Jordan. We compared intakes of the different food groups among CRC patients (n=167) and matched controls (n=240) by age, sex, occupation, and marital status. A validated food frequency questionnaire was used to collect dietary data. Logistic regression was used to evaluate the association of quartiles of intakes of the different food groups with CRC risk. In addition, the association of selected food items with CRC risk was examined. Odds ratios (ORs) for the fourth versus the first quartile of intake were 2.92 [95% confidence interval (CI): 1.40-6.08] for grains, 1.66 (95% CI: 0.81-3.40) for vegetables, 0.55 (95% CI: 0.26-1.16) for fruits, 0.96 (95% CI: 0.46-1.97) for milk, and 1.43 (95% CI: 0.68-2.98) for meat and legumes. In a comparison of the highest with the lowest weekly frequency of consumption, there was a direct association between the risk of CRC and the frequency of consumption of chicken (OR=2.52, 95% CI: 1.33-4.77). An increase in risk was observed with increased consumption of white bread (OR=3.13, 95% CI: 1.18-9.25), whereas consumption of whole bread was associated with a decreased risk for CRC (OR=0.32, 95% CI: 0.12-0.84). Our results support a role of diet in CRC. Direct associations were found for grains, white bread, and chicken, whereas an inverse relation was reported for whole bread.

OBJECTIVE: Diet and lifestyle have been reported to be important risk factors for the development of colorectal cancer (CRC). However, the association between total energy and nutrient intake and the risk of developing CRC has not been clearly explained. The aim of our study is to examine the relationship between total energy intake and other nutrients and the development of CRC in the Jordanian population. RESEARCH METHODS AND PROCEDURES: Dietary data was collected from 169 subjects who were previously diagnosed with CRC, and 248 control subjects (matched by age, gender, occupation and marital status). These control subjects were healthy and disease free. Data was collected between January 2010 and December 2012, using interview-based questionnaires. Logistic regression was used to evaluate the association between quartiles of total energy, macro- and micronutrient intakes with the risk of developing CRC in our study population. RESULTS: Total energy intake was associated with a higher risk of developing CRC (OR = 2.60 for the highest versus lowest quartile of intake; 95% CI: 1.21-5.56, p-trend = 0.03). Intakes of protein (OR = 3.62, 95% CI: 1.63-8.05, p-trend = 0.002), carbohydrates (OR = 1.41, 95% CI: 0.67-2.99, p-trend = 0.043), and percentage of energy from fat (OR = 2.10, 95% CI: 0.38-11.70, p-trend = 0.009) significantly increased the risk for the development of CRC. Saturated fat, dietary cholesterol and sodium intake showed a significant association with the risk of developing CRC (OR = 5.23, 95% CI: 2.33-11.76; OR = 2.48, 95% CI: 1.18-5.21; and OR = 3.42, 95% CI: 1.59-7.38, respectively), while vitamin E and caffeine intake were indicative of a protective effect against the development of CRC, OR = 0.002 (95% CI: 0.0003-0.011) and 0.023 (95%CI: 0.008-0.067), respectively. CONCLUSION: Our results suggest an increased risk for the development of CRC in subjects with high dietary intake of energy, protein, saturated fat, cholesterol, and sodium, and diets high in vitamin E and caffeine were suggestive of a protective effect against the risk of developing CRC. IMPACT: This is the first study in Jordan to suggest that it may be possible to reduce CRC risk by adjusting the intake of some macro-and micronutrients.

BACKGROUND: Unexplained disturbances of liver function parameters after laparoscopic cholecystectomy have been reported in a few previous studies. We aimed to assess the incidence of these disturbances, and their relation to age, sex, duration of surgery, and type of gallbladder inflammation, as well as their clinical significance. PATIENTS AND METHODS: All patients undergoing laparoscopic cholecystectomy at Dallah Hospital, Riyadh, Saudi Arabia, during the year 2001 were prospectively evaluated. In all the patients, six parameters of liver function (direct bilirubin, indirect bilirubin, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, and gamma-glutamyltransferase) were assessed before and 24 hours after surgery. Patients with suspected chronic liver disease or common bile duct pathology were excluded. Patients who showed more than a 100% increase in at least one parameter (group I) were compared with those who did not (group II) regarding age, sex, duration of surgery, and type of gallbladder inflammation. RESULTS: Of the patients, 67.1% showed more than a 100% increase in at least one parameter of liver function. No significant difference was noticed between the two groups regarding age, duration of surgery, or type of gallbladder inflammation. Female patients, however, showed a significantly higher incidence of liver function changes (P = .011). No clinical adverse reactions were reported in those who showed liver function changes. CONCLUSION: Changes in liver function parameters after laparoscopic cholecystectomy are common, carrying no clinical sequalae. They are more common in female patients and are not related to age, duration of surgery, or the acuteness of gallbladder inflammation. Assessment of direct bilirubin and alkaline phosphatase is sufficient for the routine evaluation of these patients postoperatively.

BACKGROUND AND PURPOSE: Studies have shown the safety and effectiveness of laparoscopic cholecystectomy (LC) for acute cholecystitis (AC). Our aim was to establish the outcome of LC in patients with AC on the basis of duration of the attack before surgery took place, the type of gallbladder inflammation, and patient sex. PATIENTS AND METHODS: All 204 patients at Princess Basma Teaching Hospital who underwent LC for AC by the authors between September 1994 and June 1999, were retrospectively reviewed. They were categorized into Group I, where surgery took place within 72 hours of the acute attack (N = 78; 54 women and 24 men), and Group II, if later than that (N = 126; 70 women and 56 men). Gallbladder pathology was classified as gangrenous, empyema, edematous, mucocele, or AC along with contracted fibrosed gallbladder. RESULTS: Conversion to open cholecystectomy was needed in 12% of the total series. In Group I, 3.8% of the patients needed conversion compared with 16.7% in Group II patients (P = 0.01). Also, 4% of the female patients needed conversion compared with 24% of the male patients (P = 0.000). There was an association between the pathological type of AC and the likelihood of conversion (P = 0.002), conversion being least common in those with mucocele and most common in those with empyema and gangrene. The median operation time was 75 +/- 36 minutes, but the operation time for Group II patients was significantly longer (P = 0.001) than in Group I patients. Operation time in the male patients was significantly longer than in the female patients (P = 0.000). There was no statistically significant difference in the duration of hospital stay in the two groups or in men and women. There were no deaths or main bile duct injuries in the series. In successful LC, missed stones occurred in 3.3% of the patients. Bile collection, which was treated by open surgery, developed in one female patient. CONCLUSION: Laparoscopic cholecystectomy is a reliable and safe modality for the management of AC. It was not associated with an increased incidence of bile duct injury in this series. It should be the first choice before resorting to open surgery. Factors associated with increased conversion include delay in surgery of more than 3 days from the acute attack and certain pathology, with conversion being more likely in empyema. Conversion also was more likely in male patients.

OBJECTIVE: Juvenile polyposis syndrome is a rare autosomal dominant disorder with incomplete penetrance. The aim of this study was to review our experience with juvenile polyposis syndrome with emphasis on the diversity of polyp pathology and distribution and the recommended treatment. METHODS: Over the period January 1994 through February 2001, 10 family members were managed at Princess Basma Teaching Hospital, Irbid, Jordan. Two siblings with juvenile polyposis syndrome are discussed. RESULTS: The polyps were unusually concentrated in the rectum. In one patient the polyps were purely of the adenomatous type. The father suffered from non-polyposis colon cancer at the age of 35. CONCLUSION: Proctocolectomy and ileal pouch-anal anastomosis is recommended as the treatment of choice. Screening of juvenile polyposis syndrome patients and their relatives is emphasized for early detection of malignancy.

OBJECTIVE: To determine the incidence of colorectal cancer (CRC) in young Jordanians and to compare the clinical and pathological characteristics with those in older patients and with those in high risk populations. METHODS: Clinical and pathological data of all the patients with CRC managed at Princess Basma Teaching Hospital, Irbid, Jordan over a 10 year period (January 1990 through December 1999) were recorded. The patients were divided according to age into group one (those <40 years) and group 2 (> 40 years). The 2 groups were compared regarding sex, predisposing conditions, tumor stage at presentation, tumor differentiation, mucin secretion, tumor invasion, presentation with complications and tumor location. The data were compared with those of "high risk" Western populations and with the few reports coming from "low risk" populations, mainly from Kingdom of Saudi Arabia and Egypt. RESULTS: Out of 202 patients evaluated, 4 were excluded. Group 1 constituted 20.2% of the patients, 17.5% of them have predisposing conditions. Comparison between group 1 and 2 revealed the following: female sex (65% versus 50.6%, p=0.104), advanced stages at presentation (65% versus 41%, p=0.005), rectal tumors (50% versus 39.2%) and right side tumors (15% versus 29.1%) (p=0.18). Mucinous and signet ring tumors (30% versus 15.8%, p=0.04), poor tumor differentiation (20% versus 18.3%, p=0.78) and presentation with complications (21% versus 22.2%, p=0.96). CONCLUSION: The incidence of CRC in young Jordanians was much higher than high risk populations. Half of the tumors were rectal. Young patients have more advanced stage and more mucin secreting tumors. The relative high frequency and frequency of predisposing conditions calls for family screening and surveillance in the presence of predisposing conditions.

BACKGROUND: In evaluations of laparoscopic cholecystectomy for acute cholecystitis, the role of this technique specifically for empyema of the gall bladder has not been separately addressed. Therefore, we describe the demographic characteristics, clinical and laboratory findings, management and outcome of patients presenting with empyema of the gall bladder who were treated with open cholecystectomy or laparoscopic cholecystectomy. PATIENTS AND METHODS: Our retrospective evaluation included 1449 patients who underwent cholecystectomy over 88 months, including a 30-month period when open cholecystectomy was the standard operation and a 58-month period when laparoscopic cholecystectomy became the standard operation for acute and chronic cholecystitis. RESULTS: Of the 1449 cholecystectomies, 29 cases proved to have empyema, an incidence of 2%. Males constituted 48.3% of the patients (vs. 22% for the whole cholecystectomy group, P < or = 0.005) and the average age was 54.6 years (vs. 43 years for the whole cholecystectomy group, P < or = 0.005). The clinical picture was indistinguishable from other forms of acute cholecystitis. Laparoscopic cholecystectomy was attempted for all the patients in the laparoscopy era with a conversion rate of 42%, significantly higher than other forms of gall bladder diseases (P=0.002). CONCLUSION: Empyema of the gall bladder is more often encountered in males and the elderly. The clinical picture is indistinguishable from other forms of acute cholecystitis and a preoperative diagnosis is difficult. Early laparoscopic cholecystectomy is advisable for all patients with acute cholecystitis. A higher conversion rate is expected for patients with empyema.
