Abstract Aim To compare the proportions of malignancy between two modelled cohorts of referred and investigated by our colorectal 2 WW referrals pathway. Methods Two modelled cohorts were analysed from our prospectively maintained colorectal 2WW referrals database from August 2018 to July 2019. One cohort (group A) included patients without anemia, rectal mass or overt rectal bleeding. The other (group B) included the rest of referrals. Data collected and analysed in each group included total numbers of referrals, investigated referrals and malignancy proportion in each group. One tailed Z test was used to analysis statistical difference. Results 4240 referrals were made to our colorectal 2 WW pathway during the given period. 1333 (31%) were group A and 2907 (69%) were group B. Total number of patients investigated in group A was 1227, of those only 34 (2.8%) were colorectal cancer and 18 (1.5%) were extracolonic cancer. One the other hand, 2705 patients were investigated in group B, colorectal malignancy were found in 142 (5.3%) patients and 33 (1.2%) were extracolonic. There was a significant difference (p < 0.05) in total number of malignancies between Group A (53/4.3%) and Group B (175/6.5%). Conclusion While the 2 Week-Wait referral pathway plays an important role in rapid testing and identifying colorectal cancer, there was a difference between malignancy distribution within the referrals. this difference doesn’t reflect a clinical significance but it can be a good stratification tool.

Abstract Background Colorectal cancer (CRC) is one of the leading causes of mortality and morbidity in the world. It is the third most common malignancy after lung & breast and the fourth leading cause of cancer-related deaths worldwide, accounting for approximately 1,400,000 new cases and about 700,000 deaths worldwide. Objectives The aim of this retrospective study is to compare the epidemiology, clinicopathologic features, different treatment modalities and outcomes regarding disease free survival (DFS), progression free survival (PFS) & overall survival (OS) of colorectal cancer disease between cases presented to Ain shams university hospital & to Luxor international hospital in 3 consecutive years. Patients and Methods The study is retrospective comparative study. Clinical oncology department in Ain Shams University Hospital and Luxor International Hospital. The data Collected from January 2013 to December 2015. This study analyzed hospital records of patients who diagnosed with colorectal cancer (CRC) and allocated into two groups: Group A: CRC patients presented to Ain-Shams University Hospital from January 2013 to December 2015, group B: CRC patients presented to Luxor International Hospital from January 2013 to December 2015. Results There was no statistically significant difference regarding age parameter in LIH when compared to ASU, but the study was consistent with higher incidence in patients who were aged more than forty- accounted about 70.5% in all CRC cases. Cases less than 40 years old, in group A were 35.2%, while in Group B were 23.5%. Even there was no statistically significant difference but it may be attributable to more westernization in Lower Egypt. Other explanation may be due to decreased low socioeconomic status and different lifestyle factors in more developing region what increase risk of colorectal cancer. Among our cases, there is no statistically significant difference regarding gender between the two hospitals. Both sexes almost were affected equally, females appeared to be at a slightly higher risk of developing CRC cancer with current prevalence 1.3:1 in ASU group, and 1.1:1 in LIH group. Conclusion The need to increase awareness about CRC in Egypt especially upper Egypt, is recommended. An awareness campaign should be performed to promote detection of CRC at its earliest and most curable stage by recognizing early symptoms and enabling early referrals for colonoscopy. Those at higher risk should be offered more intensive surveillance. Similarity of the data from different centers suggests that this is the picture of colorectal cancer typical of Egypt.

Objective The purpose of this randomized study was to evaluate the effect on graft patency by adding clopidogrel to aspirin in off-pump coronary artery bypass (OPCAB) grafting and the possible side effects of such therapy. Methods Twenty patients who underwent standard OPCAB through median sternotomy were randomized immediately after surgery in two groups. Patients in group A (n = 10) received 100 mg of aspirin starting preoperatively, continuing indefinitely. Patients in group B received 100 mg of aspirin and, in addition, 75 mg of clopidogrel starting immediately after the operation and for 3 months. Postoperative bleeding and other perioperative parameters were compared. Angiography was repeated 3 months after surgery to determine the patency and quality of grafts. Results Preoperative risk factors were similar in the two groups. There was no significant difference in average number of distal anastomosis (P = 0.572), operation time (P = 0.686), postoperative bleeding (P = 0.256), ventilation time (P = 0.635), and intensive care unit stay (P = 0.065). Length of stay was shorter in group B (P = 0.024). There was no postoperative complication in either groups. Eight of 27 grafts in group A and 2 of 29 grafts in group B (P = 0.037) were occluded at the time of control angiography. Conclusions Early administration of a combined regimen of clopidogrel and aspirin after OPCAB grafting is not associated with increased postoperative bleeding or other major complications. Despite the small number of patients in this study and small number of examined grafts, the results suggest that the addition of clopidogrel may increase graft patency after OPCAB grafting.

Abstract Background Tuberculosis (TB) remains a significant public health concern, and exposure in healthcare settings is prevalent. Current guidelines recommend testing for TB by acid-fast bacilli (AFB) smear microscopy with 3 sputum samples and/or using nucleic acid amplification test (NAAT), and mycobacterium culture. The purpose of this project is to compare how different TB diagnostic tests affect the duration of stay in respiratory isolation. Methods This study was conducted at the Veteran Affairs South Texas hospital, which includes a total of 437 beds. Data were collected retrospectively from medical records. Eligibility included patients admitted to the hospital and placed in airborne isolation for TB screening and diagnosis, had 3 sputum samples collected 8 hours apart and/or had 2 PCR MTB/RIF. Patients were excluded if they had TB or were not undergoing evaluation for TB. Three time periods analyzed included, 3 AFB sputum samples analyzed in-house from December 2012 to January 2014 (Group A), 3 AFB sputum samples analyzed at outside facility during 2013 to 2014 as well as 2 months in 2012 (Group B), and 2 MTB PCR/RIF in house during 2017 and 2018 (Group C). Duration of isolation was compared between groups using the Kruskal–Wallis test. A total number of 815 patients were screened, leaving 105 patients for analysis after exclusion. There were 49 patients analyzed from Group A, 28 from Group B, and 28 from Group C. Results Crude analysis of the data showed numerical differences in the total number of days and hours in isolation between the 3 groups. The average (mean) days in isolation were 4.2 for Group A, 7.4 for Group B, and 5.5 for Group C. There was no statistically significant difference in either days or hours of airborne precautions by “rule out” method. Days of isolation in airborne precautions (median IQR) was 4 for all groups (P = 0.3313). Likewise, hours of airborne precautions had a median IQR of 96 for all groups P = 0.4347. Conclusion Although there was no statistical significance between the groups, crude analysis did show a numerical difference in the mean total airborne days and hours. Lack of statistical difference may be due to low number of patients, timing of order placement for in-house PCR, and longer than expected stay in airborne precautions.

610 Background: Both bevacizumab (Bev) and anti-EGFR agents are sequentially used for metastatic colorectal cancer (mCRC). Some basic studies reported the interaction between Bev and anti-EGFR agents in vivo. Therefore we hypothesized the shorter Bev-free interval may lead to poor outcome of anti-EGFR therapy. The aim of this study is to examine the association of the interval between last Bev administration and initial anti-EGFR agents with efficacy of anti-EGFR therapy. Methods: We retrospectively reviewed consecutive mCRC patients who underwent combination therapy of anti-EGFR agents and irinotecan after failure of fluoropyrimidines, oxaliplatin, irinotecan, and Bev at a single institution. We divided patients in two groups (group A: the interval between Bev and anti-EGFR agents <6M, group B: ≥6M). Results: A total of 114 patients constituted the cohort of analysis. The median age was 63; 78 (68%) patients were male. Most patients (N=100, 88%) were treated with cetuximab, and 14 patients were panitumumab. Seventy-four patients were group A and 40 patients group B, respectively. There was no significant difference in patient characteristics. Response rate was 24.7% in group A, and 50.0% in group B (p=0.0072). The patients in group B have significantly longer progression free survival (4.2 vs. 6.6 M, HR 0.65, 95% CI 0.43- 0.98, p=0.042) and longer overall survival (11.6 vs. 14.3 M, HR 0.62, 95% CI 0.39- 0.97, p=0.038). Conclusions: The short interval (<6M) between last Bev and anti-EGFR agents may interfere with the efficacy of anti-EGFR therapy.

725 Background: The safety and feasibility of laparoscopic surgery (LAP) for colorectal cancer has not yet been fully evaluated in elderly patients. The aim of this study was to compare the short term surgical outcomes of LAP and evaluate the safety and feasibility of LAP in colorectal cancer patients aged > 75 years. Methods: This retrospective study enrolled consecutive patients who underwent laparoscopic surgery for colorectal cancer between April 2013 and March 2014 at Yokohama City University Hospital and its related general hospitals. The patients were categorized into two groups: elderly patients (≧75 years of age: group A) and non-elderly patients ( < 75 years of age: group B). Surgical outcomes and postoperative complications were compared between the two groups. The severity of complications was evaluated using the Clavien–Dindo classification. Results: A total of 237 patients were evaluated in the present study. Eighty-four patients were classified into group A, and 153 into group B. Preoperative clinicopathological outcomes demonstrated no significant differences except for the ASA score. When comparing the surgical outcomes between group A and group B, the rate of conversion to open procedure (3.6 % vs 5.2 %, P = 0.751), median operation time (232 min vs 232 min, P = 0.318), median blood loss (20 ml vs 12 ml, P = 0.353). There was no significant difference in the surgical outcomes. Although the incidence of Japanese D3 dissection was significantly lower in Group A (56 % vs 69.3 %, P = 0.047), the incidences of postoperative surgical complications of grade ≧ Ⅱ were similar between two groups (15.5 % vs 11.8 %, p = 0.427). The length of postoperative hospital stay was also similar (10days vs 10days, p = 0.347). Conclusions: The present study suggested that laparoscopic surgery for colorectal cancer is safe and feasible, regardless of the age of the patient, especially for elderly patients who may be candidates for colorectal cancer surgery.

Objective: We wanted to see whether impacted third mandibular molar extractions resulted in Alveolar Osteitis if post-extraction socket irrigation was used or not. Methodology: A randomized control experiment on 70 patients study was conducted from July 2019 to January 2020 at Islamabad Dental Hospital's OMFS department. Patients presenting with the mandibular third molars fulfilling the inclusion criteria had their teeth extracted with and without socket irrigation using the computer lottery method. In cases of dry socket, clinical diagnosis was made between the 3rd, 5th, and 7th postoperative days. Results: 70 patients/sockets were evaluated with 35 having been irrigated and 35 non-irrigated. The age range was 16-50years with a mean of 29.49 and most patients were between the 16-35 age group. There were 48.6% males and 51.4% females. Dry Socket was evaluated on the 3rd, 5th, and 7th day between groups (A=irrigation, B=Non-irrigation). On the 3rd postop day, 14 (40%) patients in group A and 15(42.9%) patients were diagnosed as dry Sockets. A similar number of patients in both groups (20%) exhibited symptoms of dry socket on the fifth and seventh postoperative days, as did 5 (14.3 %) in group A, 3 (8.6 %) in group B, and 1(2.9 %t) in group A, all on the fifth postoperative day. Conclusion: On the third, fifth, and seventh postoperative days, there was no significant difference in the result of Alveolar Osteitis between the groups.

Purpose: The purpose of this study is to analyze the possible change in the characteristics of patients with colonic ileus from obstructive colorectal cancer in UMHATEM "N. Pirogov ". Material and Methods: For two separate periods of 2 years in the Department of General, Visceral and Emergency Surgery in University Hospital "N. I. Pirogov" from ileus caused by colorectal carcinoma were operated respectively: Group A (1.1.2010-31.12.2011) - 187 patients (average 71.2 years, women were 88, men 99) Group B (1.1.2014-31.12.2015) - 141 patients (average 73.5 years, women were 69, men 72). Results: In group B there was an increase in the infected patients at an earlier stage. There was no significant difference in the localization of the tumor process in the two groups. In contrast to the increased number of patients hospitalized at an earlier ileus stage, there was no difference in the two groups according to the tumor stage. Conclusions: Emergency surgery is indicated for cases with full bowel obstruction and significant prediction of rupture. Surgery procedure like proximal colostomy is reccomended for elderly patients and complicated comorbidity. Primary procedure like segmental and subtotal colectomy is appropriate for patients in good condition. Segmental resection is favorable in elderly patients and those with shock who may not tolerate lengthy surgery.

Hematological indication is an important finding for pathophysiology analysis of biological science. This study was designed with the aim to investigate the effects of residual antibiotics on hematological parameters of broiler following discriminate and indiscriminate use. 18 broiler DOC (Cobb-500) were reared up to 31 days. On day 16, they were randomly divided into 3 groups, namely Group–A (Control group), Group-B (Discriminate group) and Group-C (Indiscriminate group). Each group contains 6 birds. The discriminate and indiscriminate group was treated with antibiotic, enrofloxacin. In Group-B withdrawal period was followed and treatment was stopped before 7 days of sacrifice. On the other hand, withdrawal period was not maintained in indiscriminate group and the antibiotic treatment was continued until the day of sacrifice. The Total erythrocyte count (million/mm3) of control, discriminate, and indiscriminate groups were 3.15±0.047, 2.66±0.091, and 2.90±0.11 respectively. The Hb (gm%) of control, discriminate, and indiscriminate groups were 8.17±0.07, 7.37±0.09, and 7.28±0.07 respectively. The Packed Cell Volume (%) of control, discriminate, and indiscriminate group were 24.17±0.48, 23.17±0.48, and 22.33±0.67 respectively. There was no significant difference on blood parameter found among the groups. Therefore, discriminate and indiscriminate use of enrofloxacin has no bad effect on hematological parameters of broiler.

Introduction: Recurrent laryngeal nerve (RLN) injury one of the most serious complications of thyroid, parathyroid and cervical spine surgery. Injuries to external branches of superior laryngeal nerves are described as uncommon. This complication is so severe that it may actually result in disability of voice professionals (like teachers, singers, actors, speakers, managers, etc.). Enhanced efforts are developed in the current clinical practice to increase intraoperative RLN protection through electrophysiological monitoring of laryngeal innervation and simultaneous RLN visualisation. Methods: The study was designed as a prospective observational study. A set of 100 consecutive procedures was selected from the overall set, randomised by surgeons to two groups: A – neuromonitoring (IONM) was used; B – RLN identification and visualisation without IONM. One team included an expert (more than 1000 procedures) and a surgeon in training (less than 100 procedures), and the other team includeda two experienced surgeons (one with more than 150 procedures and the other with more than 500 procedures). Each team performed several procedures a week. The comparison was performed using statistical methods and using the Index of Recurrent Injury (IRI). The purpose of the study was to compare the incidence of RLN paresis in procedures using neuromonitoring (IONM) and intraoperative visualisation of the anatomic non-injured nerve, performed by the two teams. Results: We analysed 100 consecutive thyroid surgeries, 50 procedures both in group A and B. Group A included 43 total thyroidectomies and 7 hemithyroidectomies. Two cases of one-side temporary RLN palsy were found and IRI was 1.075. Group B included 48 total thyroidectomies and 2 hemithyroidectomies. Two cases of one-side temporary RLN palsy were found, as well, and IRI was 1.02. The IRI values thus characterise asymmetric patient sets, and although minor, the asymmetry is reflected in the result. Overall incidence of RLN injuries in the entire set of selected procedures followed during the given year was 1.3%. The set included 16 temporary and 4 permanent RLN palsies, unilateral in all cases. No bilateral permanent or temporary palsy was observed in the followed period. Thyroid surgery IRI was 2.26 in this period. The set was compared to group A and group B patients; the results show no statistically significant differences on 1% significance level (p=0.01). Conclusions: The study showed no statistically significant differences in RLN incidence (permanent unilateral palsy) between procedures without and with IONM, performed by surgeons with different levels of experience in thyroid surgery. As shown by the study, IONM can be helpful for surgeons in training and less experienced surgeons and it can limit the incidence of RLN morbidity in thyroid surgery.
