Feasibility and Safety of Laparoscopic Complete Mesocolic Excision (CME) for Right-sided Colon Cancer: Short-term Outcomes. A Randomized Clinical Study.

OBJECTIVE: The aim of this prospective clinical study is to compare short-term outcome of laparoscopic right hemicolectomy using the Complete Mesocolic Excision (CME group) with patients who underwent conventional right-sided colonic resection (NCME group). SUMMARY BACKGROUND DATA: Although CME with central vascular ligation in laparoscopic right hemicolectomy is associated with a significant decrease in local recurrence rates and improvements in cancer-related 5-year survival, there may be additional risks associated with this technique because of increased surgical complications. As a resul

There is debate regarding which is the optimal appro … vein was anastomosed to the SMA in a side-to-side fashion with the distal vein tunneled through the mesocolon and anastomosed in a end-to-side fashion to the hepatic artery. Statistical analysis was done using Student's t-test, Mann-Whitney U test, Fisher's exact test, and log-rank test with a P ≤ 0.05 considered significant. RESULTS: Forty-one patients un …

Posterior 'superior mesenteric artery first' approach for resection of locally advanced pancreatic cancer.

BACKGROUND: En bloc resection of the superior mesenteric vein (SMV), portal vein (PV), and/or splenic vein (SV) with concomitant venous reco … approval was required. RESULTS: The operation begins by dividing the attachment of the transverse mesocolon to the right perinephric area and extending this down to the white line of Toldt, followed by a wide Kocher maneuver. The lateral attachments to the pancreatic head are then divided, thereby exposing the left renal vein. The lesser sac is entered di …

Dissect the fascia plane between right gastroepiploic mesentery (RGEM) and transverse mesocolon. Turn to the pancreas head, remove the covering adipose tissues, identify the superior mesentery vein and expose the origins of right gastroepiploic vessels (RGEVs). Clip and cut. All the surrounding mobilized adipose tissues are defined as RGEM [10 …

Lymph node metastasis in cancer progression: molecular mechanisms, clinical significance and therapeutic interventions.

Lymph nodes (LNs) are important hubs for metastatic cell arrest and growth, immune modulation, and secondary dissemination to distant sites through a series of mechanisms, and it has been proved that lymph node metastasis (LNM) is an essential prognostic indicator in many different types of cancer. Therefore, it is important for oncologists to understand the mechanisms of tumor cells to metastasize to LNs, as well as how LNM affects the prognosis and therapy of patients with cancer in order to provide patients with accurate disease assessment and effective treatment strategies. In recent years
