This scientific study aims to evaluate the effects of bowel preparation on the outcomes of scheduled colorectal surgery. The study included a group of 83 patients, 37 without bowel preparation and 46 with bowel preparation. Perioperative outcomes of patients were evaluated, including surgical site infection (SSI) rates, postoperative complications, and length of hospital stay. The results concluded that bowel preparation before scheduled colorectal surgery has no superiority in reducing SSI and postoperative complications (anastomotic leakage, occurrence of abdominal or pelvic abscesses), as well as shortening the length of hospital stay, and did not show any clear advantage over the patients without mechanical bowel preparation.

Research summary
تهدف هذه الدراسة إلى تقييم تأثير تحضير الأمعاء على نتائج جراحة القولون والمستقيم المبرمجة. شملت الدراسة 83 مريضًا، حيث تم تقسيمهم إلى مجموعتين: 37 مريضًا لم يخضعوا لتحضير الأمعاء و46 مريضًا خضعوا لتحضير الأمعاء. تم تقييم النتائج المحيطة بالجراحة مثل معدلات انتان ساحة العمل الجراحي (SSI)، المضاعفات بعد الجراحة، وطول مدة الإقامة في المستشفى. أظهرت النتائج أن تحضير الأمعاء لم يكن له تأثير كبير في تقليل معدلات SSI أو المضاعفات بعد الجراحة مثل التسريب من المفاغرة أو حدوث خراجات بطنية أو حوضية، ولم يساهم في تقليل مدة الإقامة في المستشفى. بناءً على هذه النتائج، يمكن القول أن تحضير الأمعاء الميكانيكي ليس ضروريًا قبل جراحات القولون والمستقيم المبرمجة، ويمكن إجراء هذه الجراحات بأمان دون زيادة الخطورة على المرضى.
Critical review
دراسة نقدية: تعتبر هذه الدراسة خطوة مهمة في تقييم فعالية تحضير الأمعاء قبل جراحات القولون والمستقيم. ومع ذلك، هناك بعض النقاط التي يمكن تحسينها. أولاً، حجم العينة صغير نسبيًا، مما قد يؤثر على قوة النتائج. ثانيًا، لم يتم توضيح بعض التفاصيل الهامة مثل المعايير الدقيقة لاختيار المرضى وتوزيعهم بين المجموعتين. ثالثًا، الدراسة تعتمد على بيانات بأثر رجعي، مما قد يؤدي إلى بعض التحيزات. على الرغم من ذلك، تقدم الدراسة إسهامًا قيمًا في النقاش حول ضرورة تحضير الأمعاء قبل الجراحة، وتدعو إلى إجراء مزيد من الدراسات المستقبلية بأحجام عينات أكبر وبروتوكولات موحدة.

Introduction: Liver surgery is a relatively recent and relatively major complex surgery, due to the anatomical and histological specialty of the liver Objective of the research: To evaluate the results of the cases of liver metastases from colorec tal carcinoma from November 2010 until the end of April 2017.The study included 11 patients with 63,4% of females and average age of 55,4 years. The primary tumor was located in the rectum at 36.4%. in 4 cases (36.4%) was the livermetastases as a synchron with the main tumor while the metachron metastases was in 63.6% of cases. The single metastases was found at 72.7% while the multiple metastases accounted for 27.3%. The transfusion diameter was less than 5 cm in 5 cases and 45.4% and it was larger or equal to 5 cm in 54.6% of all the cases. The liver resection for Hepatocellular lesions were performed concurrently with primary tumor resection in the colon in only one case and the metastases was a single and 9.1% of the cases. The most common surgical procedure was segment resection in 45.4% of all the cases. The left or right hemi hepatectomy was in two cases, 8.7% None of the patients had any complications which requiring a reoperation. Bleeding occurred in one case such as the Bilioma in one case and Biliary fistula occurred in two cases.
This retrospective study aims to assess the causes of the small bowel obstruction and their management during the last six years (1998-2003) in the Central Emergency Department at Al-Mowassat University Hospital in Damascus. This study included 163 patients, treated surgically and urgently for small bowel obstruction.
We conducted a randomized clinical trial on 32 subjects in 2 groups with chronic diseases of the sphenoid sinus (each consisting of 16 patients) to evaluate CT navigation during Functional Endoscopic Sinus Surgery. All patients registered in our st udy met the widely accepted criteria to be treated with FESS. 16 patients were operated on with FESS with CT navigation while 16 patients were operated on with FESS without navigation. The result drawn showed no significant statistical difference in the outcome of the operations when we used the CT navigation during FESS compared with the time we did not use it. However, we believe it is an asset to the ENT surgeon in difficult and critical operations like the sphenoid sinus surgery as it brings precision and peace to the surgeon. We recommend using CT navigation as a useful adjunct added to the surgeon’s knowledge & experience but not as a replacement to these necessities.
the lapse of rhinoplasty results in cleft lip patients is considered one of the challenges which limit of plastic surgery in oral facial deformities This research aimed to evaluate the usage of two kinds of nasal stints (plastic and acrylic) at the results of rhinoplasty in cleft lip patients.
Although complications of arteriovenous fistula infrequent, but they occur, the most important and common complications are: thrombosis, infection, stenosis vascular, bleeding, aneurysm, ischemia. It was observed that preparation and good care of AVF have an important role in reducing complications in addition to accelerate the maturation of arteriovenous fistula. Implementing A protocol of Postoperative Arteriovenous Fistula Care Contributes in preventing complications and improve the maturation of arterial venous connection. Objective: This study was conducted to determine the effect of the application of the policy of nursing care on the clinical outcomes of the arterial venous connection postoperatively in patients with end stage renal disease. Goal: the aim of the present study was to determine the effect of Implementing A Protocol Of Postoperative Arteriovenous Fistula Careon clinical outcomes in patients with end stage renal disease. Materials and Methods: the study was conducted at AL-Assad University Hospital (Lattakia), a convent sample of 20 patientsin the renal dialysis department and the Department of Surgery. Clinical results for AVF were evaluated and the results of application policy of nursing care to of AVF in the control and experimental groups after 40 days of follow-up by using tow development tools: Sociodemographic Data and Arteriovenous Fistula Assessment Sheet. Results: our results demonstrated important of application of A Protocol Of Postoperative Arteriovenous Fistula Care. It decreased the complications in the experimental group and improve maturation of AVF mostly in the twentieth day of the study, while there was complications higher and delay in the maturation of AVF to the fortieth day of the study and after in the control group, which left for routine hospital. Conclusions and recommendations: our present study results advice to apply a protocol of Postoperative Arteriovenous Fistula Care because its affect in decrease and preventing complication in addition to improve maturation of AVF on ESRD patients
