Survival rates for infants and children who have choledochal cyst with or without spontaneous rupture have improved dramatically in the past decades. Despite excellent long-term survival for patients with choledochal cyst who undergo elective surgery, many significant complications can occur in the patients being operated in emergency for rupture of the cyst. Spontaneous rupture of the cyst is one such problem resulting in considerable morbidity and mortality in these patients. Majority of surgeons manage these cases with T-tube external drainage. The conventional methods of T-tube placement for long period has remained simple as described in choledochotomies where there is no deficit of the walls of common bile duct (CBD). The present technique has been designed specially for the cases of ruptured choledochal cyst, where the wall of the CBD gets necrosed leaving behind a long gap between the two ends. In these cases, placement of T-tube with conventional method is not possible because there is no wall to suture together, and make the CBD water tight again to prevent leakage of bile. We found only two patients of spontaneous rupture of choledochal cyst with a long gap between two ends of CBD because of necrosed anterior wall. In both of these patients, it was not possible to put T-tube with traditional method and one would have to opt for primary definitive repair despite poor general condition of patients.

Background/Aim: Current guidelines recommend screening cirrhotic patients with an endoscopy to detect esophageal varices and to institute prophylactic measures in patients with large esophageal varices. In this study, we aimed at identifying non-endoscopic parameters that could predict the presence and grades of esophageal varices. Patients and Methods: In a prospective study, 229 newly diagnosed patients with liver cirrhosis, without a history of variceal bleeding, were included. Demographic, clinical, biochemical and ultrasonographic parameters were recorded. Esophageal varices were classified as small and large, at endoscopy. Univariate analysis and multivariate logistic regression analysis were done to identify independent predictors for the presence and grades of varices. Results: Of the 229 patients (141 males; median age 42 years; range 17-73 years) with liver cirrhosis, 97 (42.3%) had small and 81 (35.4%) had large varices. On multivariate analysis, low platelet count (Odd's Ratio [OR], 4.3; 95% confidence interval [CI], 1.2-14.9), Child Pugh class B/C (OR, 3.3; 95% CI, 1.8-6.3), spleen diameter (OR, 4.3; 95% CI, 1.6-11.9) and portal vein diameter (OR, 2.4; 95% CI, 1.1-5.3) were independent predictors for the presence of varices. Likewise, for the presence of large esophageal varices, low platelet count (OR, 2.7; 95% CI, 1.4-5.2), Child Pugh class B/C (OR, 3.8; 95% CI, 2.3-6.5) and spleen diameter (OR, 3.1; 95% CI, 1.6-6.0) were the independent risk factors. Conclusion: The presence and higher grades of varices can be predicted by a low platelet count, Child-Pugh class B/C and spleen diameter. These may be considered as non-endoscopic predictors for the diagnosis and management of large grade varices.

Crohn's disease (CD) is known for wide anatomic distribution, different presentations, life-threatening complications, and multiple modalities of management. Its multiple implications are still unaddressed. Since all the patients do not show a good response to medical modalities of treatment, a significant percentage of these patients are referred to the surgeon for the palliation of complications or for the ultimate curative treatment. Since most surgeons come across such patients only rarely, it is sometimes difficult for them to choose the appropriate procedure at the time of need. Moreover, the various surgical modalities available for the different presentations and complications of the disease have not been adequately discussed. The aim of this review is to offer insight and a detailed account of the management of CD from a surgical perspective. This review offers an overview of the various surgical options available, their utility in context, and an approach to various scenarios of complicated CD.

Background/Aim: This study was conducted to provide sonographic measurements of the abdominal esophagus length in neonates and infants with and without gastroesophageal reflux disease (GERD) and to investigate its diagnostic value. GERD severity was also evaluated and correlated with esophageal length. It is a prospective case-control study. Materials and Methods: This prospective case-control study comprised 235 neonates and infants (120 without reflux and 115 with reflux). There were 40 children without reflux in each of three age categories: less than 1 month, 1-6 months, and 6-12 months. Of the children with reflux, 40 were less than 1 month old; 37, 1-6 months; and 38, 6-12 months. The abdominal esophagus was measured from its entrance into the diaphragm to the base of gastric folds in fed infants. GERD was sonographically diagnosed and confirmed by a barium meal. The number of refluxes during a 10-min period were recorded. Results: Neonates and infants with reflux had a significantly shorter abdominal esophagus than subjects without reflux: the mean difference in neonates, 4.65 mm; 1-6 months, 4.57 mm; 6-12 months, 3.61 mm. Conclusions: Children with severe reflux had a shorter esophagus compared with those with mild and moderate reflux only in the neonate group. Therefore, thinking of GERD and carefully looking for its symptoms is necessary to avoid unnecessary utilization of healthcare resources in children with severe reflux.

Background/Aim: Mesenchymal hamartoma of liver (MHL) is a rare liver tumor of childhood. About 200 cases have been reported till now. Most of the work on MHL is limited to case reports and there are not many long term follow-up studies. We present our 20 years of experience with this uncommon entity. This study aims to highlight clinical features, diagnosis and treatment of MHL. Materials and Methods: All patients with a diagnosis of MHL in last 20 years were included in this retrospective study. The patients were evaluated clinically, radiologically and pathologically. Results : The total number of patients with a diagnosis of MHL was nine. Mean age of the patients was 19.89 ± 2.75 months. Right lobe was involved in eight patients. The prominent clinical features were distension of abdomen and anorexia. Surgical options used were hepatic lobectomy, wedge resection and enucleation. Histopathology of the specimens showed cysts of variable size with normal hepatocytes, bile ducts and connective tissue stroma. Overall mortality was one (11.11%). Conclusion: MHL is a benign tumor that can present with various clinical features. It should be differentiated carefully from other liver masses especially malignant ones. The diagnosis can be made with the help of radiology and histopathology. Adequate resection is curative in most of the cases and long-term follow up is satisfactory.

Background/Aim: As totally laparoscopic colorectal surgery is considered challenging and technically demanding with a long steep learning curve, we adopted hand-assisted laparoscopic colorectal surgery as a bridge to totally laparoscopic assisted colorectal surgery. This prospective study aims to highlight the initial experience of a single surgeon with this technique. Materials and Methods: A prospective analysis of the first 25 cases of hand-assisted laparoscopic colorectal resections which were performed by a single surgeon over a 15-month period. There were 15 males and 10 females with a mean age of 55.5 (range 20-82) years. Results: The indication in majority of cases was cancer (76%). The procedures consisted of 18 (72%) various colectomies and 7 (28%) anterior resections. The operative time ranged between 110-400 (mean 180) min. There was one conversion (4%) and the mean operative blood loss was 80 (range 60-165) ml. The number of lymph nodes retrieved in the cancer cases was 5-31 (mean 15) nodes. The mean length of hospital stay was five (range 3-10) days. The total number of short-term complications was six (24%) and there was one death due to anastomatic leak and multiorgan failure. Long-term complications after a maximum follow up of 30 months were two incisional hernias at the hand port site, but none of the patients developed adhesive small bowel obstruction or late anastomotic stricture. Currently all our colorectal procedures are conducted laparoscopically. Conclusion: Hand-assisted laparoscopic colorectal procedures are easy to learn as a good bridge to master totally laparoscopic colorectal surgery.

Background/Aim: Pediatric non-alcoholic fatty liver disease (NAFLD) is a global problem which has been increasingly recognized with the dramatic rise in pediatric obesity. The aim of the present study was to identify the clinical, sonographic, and biochemical predictors for NAFLD in obese children. Materials and Methods: Seventy-six children (2-15 years) were included after an informed consent. All were subjected to full anthropometric assessment (including height, weight, body mass index, subscapular skin fold thickness, waist and hip circumference and calculation of waist: hip ratio), biochemical assessment of liver function tests, lipid profile and insulin resistance and sonographic assessment of hepatic echogenicity. Liver biopsy when indicated, was done in 33 patients. Results: Sixteen patients (21%) had elevated ALT and 6 (7.9%) had elevated AST. Significant dyslipidemia (low HDL-c, high total cholesterol, high LDL-c and triglycerides) and higher insulin resistance were found in obese patients (P<0.01). The main sonographic findings were hepatomegaly in 20 patients (26.3%) and echogenic liver in 41 patients (53.9%). Liver biopsy showed simple steatosis in eight cases (24.2%) and non-alcoholic steatohepatitis (NASH) in seven cases (21.2%). Anthropometric measurements, increased hepatic echogenicty by ultrasound, insulin resistance and lipid profile were good predictors of NAFLD in obese children if assessed together. However, LDL-c was the only sensitive predictor (independent variable) for NAFLD in both uni- and multivariate logistic regression analyses. Conclusion : Dyslipidemia per se is a strong predictor of NAFLD among obese Egyptian children.

Background/Aim: Occult hepatitis B infection (OBI) is identified as a form of hepatitis in which despite the absence of detectable HBsAg, HBV-DNA is observed in peripheral blood of patients. The main aim of this study has been to investigate the association between polymorphisms in +874 of IFN-γ and +1188 of IL-12 with their serum level in patients suffering from OBI. Materials and Methods: In this experimental study, plasma samples of 3700 blood donors were tested for the presence of hepatitis B surface antigen (HBsAg) and anti-HBc by ELISA. The HBsAg ^- /anti-HBc ⁺ samples were selected and screened for HBV-DNA by PCR. HBV-DNA positive samples were assigned as OBI cases and ARMS-PCR techniques were performed to examine the two known polymorphisms within IL-12 and IFN-γ. In addition, the serum levels of IL-12 and IFN-γ were also determined by ELISA. Results: Results of this study demonstrated that, 352 (9.5%) out of 3700 blood samples were HBsAg ^- /anti-HBc ⁺ and HBV-DNA was detected in 57/352 (16.1%) of HBsAg ^- /anti-HBc ⁺ samples. Our results showed that groups showed significant difference in CC allele of +1188 region of IL-12 and no difference was observed in the other evaluated genes. Our results also showed that the alleles of +1188 region of IL-12 and alleles of +874 of IFN-γ were also not associated with serum level of cytokines. Conclusion: According to the results of this study, it may be concluded that the polymorphisms in +1188 region of IL-12 and +874 region of IFN-γ would not affect the expression of both cytokines at serum level in OBI patients.

Background/Aim: Endoscopic retrograde cholangiopancreatography (ERCP) is associated with a considerable radiation exposure for patients and staff. While optimization of the radiation dose is recommended, few studies have been published. The purpose of this study has been to measure patient and staff radiation dose, to estimate the effective dose and radiation risk using digital fluoroscopic images. Entrance skin dose (ESD), organ and effective doses were estimated for patients and staff. Materials and Methods: Fifty-seven patients were studied using digital X-ray machine and thermoluminescent dosimeters (TLD) to measure ESD at different body sites. Organ and surface dose to specific radiosensitive organs was carried out. The mean, median, minimum, third quartile and the maximum values are presented due to the asymmetry in data distribution. Results: The mean ESD, exit and thyroid surface dose were estimated to be 75.6 mGy, 3.22 mGy and 0.80 mGy, respectively. The mean effective dose for both gastroenterologist and assistant is 0.01 mSv. The mean patient effective dose was 4.16 mSv, and the cancer risk per procedure was estimated to be 2 × 10 ^-5 . Conclusion: ERCP with fluoroscopic technique demonstrate improved dose reduction, compared to the conventional radiographic based technique, reducing the surface dose by a factor of 2, without compromising the diagnostic findings. The radiation absorbed doses to the different organs and effective doses are relatively low.

Mucosa-associated lymphoid tissue (MALT) tumors are a distinct subtype of non-Hodgkin's lymphoma. Synchronous appearance of adenocarcinoma and colonic MALT lymphoma in the same patient is quite rare. In the present report, we describe a 68-year-old female who presented with a history of bleeding per rectum. She had no history of fever, loss of weight or drenching night sweats. Rectal examination revealed no abnormality. Colonoscopy showed a large ulceroproliferative mass arising from the hepatic flexure, biopsy of which came out to be adenocarcinoma of colon. A right hemicolectomy was performed and microscopic study revealed the tumor type to be synchronous adenocarcinoma with lymphoma. The final diagnosis of this patient turned out to be a synchronous manifestation of both colonic adenocarcinoma and colonic MALT lymphoma. Although the patient remains asymptomatic two years after surgery, the case highlights the therapeutic dilemma that prevails in the definitive management in such scenarios.

Primary rectal teratomas are rare and only few cases have been reported in the literature worldwide. These usually occur in females. These are usually cystic but very rarely solid variants may occur. We present a case of a solid intra-rectal dermoid arising primarily in rectum from postero-lateral wall. Excision biopsy was done per rectally. Histology revealed the presence of squamous epithelium, fat cells, hair follicles, cartilaginous material and columnar lining of glandular structures suggestive of mature teratoma. It is usually benign but may become malignant, therefore complete resection is advised.

Background/Aim: Color Doppler examination of changes in hepatic venous waveforms is being evaluated as a means of prediction of severity of portal hypertension and presence of esophageal varices. Normal hepatic venous waveform shows a triphasic pattern. In cirrhosis, this pattern changes to a biphasic or monophasic pattern. We aimed to study the sensitivity of loss of normal hepatic venous waveforms in predicting large varices in a cross-sectional analysis. Materials and Methods: All patients, admitted or attending the outpatient department, with a diagnosis of cirrhosis were included in the study. All patients were subjected to oesophagogastroduodenoscopy and Color Doppler examination, and waveform patterns in hepatic vein were recorded. The sensitivity and specificity of changes in waveform in detecting large varices were studied. Results : A total of 51 cases were examined. Triphasic waves were seen in 4 (7.8%) cases, biphasic in 26 (51%) cases, and monophasic in 21 (41.2%) cases. Small varices were seen in 30 (58.8%) cases and large varices in 21 (41.2%) cases. The sensitivity of loss of the triphasic wave pattern in detecting significant varices (Grade 3 or 4) was very high (95.23%) and negative predictive value was also high (75%). Severity of liver disease as indicated by Child-Pugh and MELD scores did not correlate with changes in hepatic venous waveforms. Conclusion : Loss of triphasic hepatic venous waveform is highly sensitive in predicting significant varices in patients with cirrhosis.

Background/Aim: Malnutrition in elderly patients is common in hospitals, and many of the age associated chronic diseases have a common factor, which is oxidative stress. The aim of the study was to evaluate the nutritional status, glutathione, and oxidant status of elderly patients. Patients and Methods: The mini-nutritional assessment (MNA) was used to determine the nutritional status of elderly patients. Glutathione concentration in the whole blood, plasma albumin, and thiobarbituric acid-reactive substances (TBARS) levels was measured spectrophotometrically by the enzymatic recycling method. In addition, length of hospital stay was estimated. All measurements were taken within 48 h after admission. Results: The results showed that more than two-thirds of the elderly were classified as at risk of malnutrition and malnourished. About 45% and 53% elevation in the TBARS was found in at risk of being malnourished and in the malnourished groups, respectively, compared to the well-nourished group, but the elevation did not reach the significant level. No significant differences in the glutathione concentration and in the length of hospital stay were found among the three mini-nutritional assessment categories. Conclusions: The study indicated the necessity of performing the MNA test for elderly upon admission to hospitals, and more attention needs to be paid to this vulnerable group of people.

Gastrointestinal perforation in neonates with anorectal malformations is extremely uncommon. Delayed patient presentation is an important factor that demands special attention. We present a neonate with anorectal malformation and meconium peritonitis following spontaneous bowel perforation. A day 1 neonate was referred with features suggested of peritonitis. After adequate resuscitation and drainage under local anesthesia, patient was successfully operated for a sigmoid perforation and is now awaiting definitive surgery for the anorectal malformation.

Background/Aim: The first option for gallbladder surgery is laparoscopic cholecystectomy. The aim of this study is to analyze the outcomes for all patients who underwent laparoscopic cholecystectomy at a secondary level of care. Patients and Methods: Between 2005 and 2008, 968 consecutive laparoscopic cholecystectomies were performed at King Fahad Hospital. We collected and analyzed data including age, gender, body mass index (kg/m ² ), the American Society of Anesthesiologists (ASA) class, mode of admission (elective or emergency), indication for LC (chronic or acute cholecystitis [AC]), co-morbid disease, previous abdominal surgery, conversion to open cholecystectomy, complications, operation time, and length of postoperative hospital stay. Results : Nine hundred and sixty-eight patients had laparoscopic cholecystectomy at the center. There were 824 females and 144 males; the age range was 15-64 (mean 32.9± 12.7 years). The operating time was 45 to 180 min (median 85 min); the complication rate was 4.03% (39 patients). Conclusion: Laparoscopic cholecystectomy could be performed safely in the majority of patients with cholelithiasis, by an experienced surgical team at a secondary level of care.
