Background and Objectives. The use of complete mesocolic excision (CME) technique seems to be gaining popularity in the management of cancer colon. We aim to compare the laparoscopic approach for CME with the open approach in right colon cancer treatment with regard to the feasibility, safety, and perioperative and oncologic outcomes. Patients and Methods. A prospective study which included all patients that underwent radical right hemicolectomy for pathologic confirmed stage II or stage III tumor with CME at South Egypt Cancer Institute, Assiut University, from January 2012 to December 2019. Patients were grouped according to the surgical approach into the laparoscopic colectomy (LCME) group (n = 48) or open colectomy (OCME) group (n = 48). Results. The mean operative time was significantly longer in the LCME group than that in the OCME group with less mean intraoperative blood loss. Conversion was required in 4 patients (8.3%) in the LCME group. The use of laparoscopy increased the number of harvested lymph nodes compared to the open approach (39.81 ± 16.74 vs. 32.65 ± 12.28, respectively, P = 0.010 ). The laparoscopic approach was associated with a shorter time interval to first flatus as well as shorter time interval to liquid and normal diet after surgery. The postoperative hospital stay was significantly shorter in the LCME group. The complication rate was slightly lower in the LCME (14.7%) than in the OCME group (27.2%) ( P = 0.252 ). The 3-year OS in the LCME group was similar to that in OCME (78.2% vs. 63.2%, respectively, P value = 0.423). The three-year DFS in the laparoscopic group was higher (74.5%) than the open group (60.0%), but did not reach statistical significance ( P value = 0.266). Conclusions. In conclusion, laparoscopic CME right hemicolectomy is a technically feasible and safe procedure if surgeon expertise is present. LCME has long-term oncologic outcomes (recurrence and survival) comparable to open surgery for management of patients with stage II or III colon cancer.
Aberrant DNA methylation status reflected by decreased mRNA expression of DNMT3A and increased plasma SAH level may play an important role in the pathogenesis of ITP, although the precise underlying mechanisms still await further investigations, and extensive work in this field is clearly needed to provide novel therapeutic targets for ITP.
Background: This study discusses the effect of obesity on the number of lymph nodes harvested during systematic LND and the LND-related complications in ovarian cancer patients. Methods: This retrospective study enrolled women with ovarian cancer who were consecutively subjected to open surgical resection that included systematic LND (pelvic and para-aortic) in the Oncology Center in Mansoura University (OCMU) during the period between January 2012 and June 2017. Patients were categorized according to the recommendations of World Health Organization by their BMI as non-obese (BMI < 30.0 kg/m 2) and obese (BMI ≥ 30.0 kg/m 2). Results: Seventy-seven women with ovarian cancer were enrolled in the study according to our inclusion and exclusion criteria. 43 females (55.8%) were grouped as obese and 34 (44.2%) as non-obese. Lymph nodes retrieved in total and in different stations separately (pelvic and para-aortic) were all similar among patients in both groups. LND-related intraoperative complications were observed in 8 patients (18.6%) in the obese group and 3 patients in the non-obese group (8.8%) (P = 0.347). Hospital stay was the same in the two groups with a median of 4 days (IQR 3-5). Postoperative complications occurred in 13 patients (30.2%) in the obese group and only in one patient (3%) in the non-obese group (P = 0.004). Conclusion: Obese ovarian cancer patients may safely undergo comprehensive staging involving extensive lymph node dissection in open surgeries without significant increase in the rates of intraoperative complications.
