Background : The hepatopulmonary syndrome (HPS) is defined as the triad of liver disease, arterial deoxygenation, and pulmonary vascular dilatation. The reported prevalence of HPS in cirrhotic patients varies between 5% -17.5%.Objective : To estimate the prevalence of hepatopulmonary syndrome among patients with chronic liver disease and portal hypertension and to study the correlation between HPS and the severity of liver disease.Patients and methods : Thirty patients were studied for the presence of HPS using transthoracic contrast echocardiography for detection of pulmonary vasodilatation. Arterial oxygen saturation (SaO2) was determined in erect and supine position using a pulse oximeter , (SaO2 ≤ 92 % in supine position and/or a d

Background: Squamous carcinoma accounts for majority of esophaged cancinoma Most patients with esophaged cancer are middle aged or elderly with make to female ratio 2.5:1.
Aim of study : to present a fairly representative picture of the carcinoma of esophagus in' yemen.
Patients& Methods: Seventy-six patients were treated for carcinoma of esophagus over a 5 - year period by cardiothoracic and vascular surgeon working in Sana a - Yemen. Amongst them there were thirty one men and forty-five women, with male/female ratio 1:1.45, age incidence (range 38 - 40year).
Results:. Adenocarcinoma was 65% of cases and other 35% was squamous cel! carcinoma. The major risk factors were founded chewing quat, silicon particles, thermal injur

Background: The removal of an impacted foreign body in the esophagus is still a common practice in the Thoracic Department of the Medical City Hospital .The objective of this study is to cast a light on this rather a common phenomenon in our country , its risks and its management.
Patients and Methods: This is a retrospective study of 120 patients with foreign bodies in the esophagus managed successfully in our department during five years period 1998 – 2002 inclusive .The study included 65 males and 55 females . Their ages range between I year and 75 years. The most common age group was less than 10 years , which constitutes about 30% of our patients .Varieties of foreign bodies were encountered ,their

BACKGROUND:Gastrointestinal bleeding (GIB) in infants and children is one of the more alarming conditions encountered in pediatrics. It is nonetheless an anxiety-provoking complaint. Most etiologies are self-limited and benign.
AIM OF STUDY:To review the causes of upper gastrointestinal bleeding and its clinical presentations in children and evaluate the role of endoscopy for diagnostic and therapeutic purposes.
PATIENTS AND METHOD:Fifty eight patients from 4 days old up to the age of 18 years who referred with upper gastrointestinal bleeding to the Gastro intestinal&Hepatology unit in the Children Welfare Teaching Hospital/ Medical City/Baghdad, in the period from 1st of April 2010 to 1st of November 2010.
RESULTS: there we

Background: Laparoscopic sleeve gastrectomy has gained more popularity as an independent bariatric procedure because laparoscopic sleeve gastrectomy was reported to be an effective, safe, and time-savingprocedure, leading to adequate weight loss for morbidly obese patients and becoming one of the most common procedures performed for the treatment of morbidly obese patients in the last few years until now.
Objectives: The aim of this study is to compare two different techniques of the reinforcement of staple line during LSG in the reduction of major complications (bleeding and leak).
Patients and methods: prospective randomized study of a consecutive series of 126 patients that underwent LSG between April 20

Tigris River water that comes from Turkey represents the main water resource of this river in Iraq. The expansion in water river implementations has formed a source of trouble for the workers in the water resources management field in Iraqi. Unfortunately, there is no agreement between Iraq and Turkey till now to share the water of this international river. Consequently, the optimal operation of water resources systems, particularly a multi-objective, multi-reservoir, is of the most necessity at the present time.

 In this research two approaches, were used the dynamic programming (DP) approach and simulation model to find the optimal monthly operation of Ilisu Dam (from an Iraqi point of view) through a comp

Construction and operation of (2 m) parabolic solar dish for hot water application were illustrated. The heater was designed to supply hot water up to 100 oC using the clean solar thermal energy. The system includes the design and construction of solar tracking unit in order to increase system performance. Experimental test results, which obtained from clear and sunny day, refer to highly energy-conversion efficiency and promising a well-performed water heating system.
