Prognostic roles and survival benefits of endoscopic resection versus surgical resection in the management of malignant colon polyps

Background: Due to few sufficient data regarding the comparison between endoscopic and surgical resection of malignant colorectal polyps regarding outcomes and survival benefits, there are no clear guidelines of management strategies of malignant colorectal polyps. The aims of the present study were to compare endoscopic resection alone and surgical resection in patients with malignant polyps in the colon (T1N0M0) readings advantages, disadvantages, recurrence risks, survival benefits, and long-term prognosis to detect how management strategy affects outcome. Patients and methods: we included 350 patients. All included patients were divided into 2 groups; the first group included 100 patients who underwent only endoscopic polypectomy and the second group included 250 patients who underwent endoscopic polypectomy followed by definitive surgical resection after histopathological diagnosis. We followed all patients for about 5 years, ranging from 18 to 55 months. The primarily evaluated parameters are surgical consequences and patients' morbidity. The secondary evaluated parameters are recurrence risks, recurrence free survival, and overall survival rates. Results: The age of patients who underwent polypectomy is usually younger than the surgical group, males have more liability to polypectomy in comparison with females. Patients with tumors in the left colon have more liability to polypectomy in comparison with the right colon (p< 0.0001). Tumor factors associated with more liability to surgical resection are presence of lymphovascular invasion, high grade, and poor tumor differentiation (p< 0.0001). The management strategy was the most significant predictor of overall and recurrence free survival rates in patients with malignant colon polyps (p< 0.001). Conclusions: We found that survival benefits and lower incidence of recurrence are detected in the surgical resection group more than in the polypectomy group. (AU)

Risk factors and outcomes of occurrence of anastomotic leakage and reoperations for its management after colorectal surgery

Background: Anastomotic leakage (AL) is still the most annoying postsurgery complication after colorectal resection due to its serious complications up to death. Limited data were available regarding differences in AL incidence, management, and consequences for different types of colorectal resection. The aim of the present work was to evaluate differences in incidence of AL, incidence of postoperative complications, and length of hospital stay in a large number of patients who underwent elective colorectal resection for management of colorectal lesions. In addition to detect when and what type of reoperation for management of AL occur after colorectal resection. Patients: All 250 included patients underwent elective surgeries for colorectal resection with performance of primary anastomosis for management of colorectal neoplastic and non-neoplastic diseases in the period between May 2016 and July 31, 2021. We followed the patients for 90 days; we registered the follow-up findings. Results: the rates of AL occurrence were variable after the different procedures. The lowest rate of AL occurrence was found in patients who underwent right hemicolectomy, then in patients who underwent sigmoidectomy, left hemicolectomy, transversectomy and anterior resection (p= 0.004). A stoma was frequently performed during reoperation (79.5%) which was significantly different between different procedures: 65.5% in right hemicolectomy, 75.0% in transversectomy, 85.7% in left hemicolectomy, and 93.0% in sigmoid resection (p< 0.001). Conclusion Rates, types, time of occurrence and severity of AL vary according to the type of colectomy performed and selective construction of stoma during AL reoperation is currently safely applied with comparable mortality rates for patients who did and who did not have a stoma after reoperation.

A comparison between different management surgical approaches in the treatment of splenic flexure colon cancer

Background: There are many surgical approaches which described extent of resection of the colon for adequate surgicalmanagement of splenic flexure cancer, but up till now there is no established surgical procedure, this is because the presence of double lymphatic drainage of themesenteric vessels. Segmental resection of the colon for the management of splenic flexure cancer was a recently accepted surgical procedure. Objective: In the present study, we aimed to compare three surgical management techniques to clarify the best management approach of Egyptian patients with splenic flexure cancer regarding operative, clinical, and oncological outcomes: segmental resection, and extended left or right hemicolectomy,. Materials and Methods In the present study, we included 90 patients with splenic flexure cancer. Cases were divided into 3 groups. Each group included 30 patients in order to compare three surgical techniques: segmental resection, extended left hemicolectomy, and extended right hemicolectomy. Results: We have found no statistically significant differences between the three included groups regarding operative findings, postoperative complications, local recurrence, distant recurrence, disease progression, recurrence-free survival rate, progression-free survival rate, and overall survival rate. The operative time was longer, and the number of lymph nodes was higher in the extended right hemicolectomy group (p<0.001). Conclusion: We have shown that segmental resection of the splenic flexure is surgically and clinically suitable for the adequate management of operable cases of carcinoma of the splenic flexure.

Serum and ascitic fluid high sensitive C reactive protein as prognostic marker in patients with spontaneous bacterial peritonitis

Background: Spontaneous Bacterial Peritonitis (SBP) is the most frequent bacterial infection in cirrhotic patients with ascites. The mortality rate in those patients ranges from 40-70%.Aim: to assess level of serum and ascetic fluid polymorph nuclear leucocytes (PMN), high sensitive C reactive protein (hs-CRP) in patients with SBP before and after treatment. Methods: A cohort study was done on 114 patients SBP admitted in the Internal Medicine, Faculty of Medicine, Zagazig University during the period from December 2017 to September 2018. All patients were subjected to full history taking, thorough clinical examination, routine laboratory investigation, ultrasonography and ascitic fluid sampling. They was followed up for 5 days from starting treatment by parenteral third generation cephalosporin and peripheral blood (PMN), serum (hs-CRP), ascitic fluid PMN and hs-CRP were measured again.Results: the largest percentage of the patients were male, had posthepatitic C cirrhosis and child C score. There was statistically non-significant difference between antibiotic responders and non-responders regarding peripheral blood PMN before or five days after antibiotic use. There was statistically non-significant difference in ascitic fluid PMN, serum and ascitic fluid hs-CRP before treatment while the difference is significant between both groups regarding them five days after treatment. Percent change in serum hs-CRP was equal to that of ascitic fluid PMN. Percent change in ascitic fluid hs-CRP was comparable to that of ascitic fluid PMN. Conclusion: Serum and ascitic fluid hs-CRP level can be considered as alternative prognostic markers in cirrhotic patients with SBP
