Laparoscopic D3 lymph node dissection for transverse colon cancer is technically demanding because of complicated anatomy. Here, we reviewed the vascular structure of the transverse mesocolon, explored the extent of the base of the transverse mesocolon, and evaluated the feasibility and oncological safety of D3 lymph node dissection. We retrospectively reviewed the clinical records of 42 patients with advanced transverse colon cancer who underwent curative surgery and D3 dissection at Kyushu University Hospital between January 2008 and December 2015...

RATIONALE: Colonic lipomas are rare benign tumours, usually without any symptoms, and most occur in the caecum and ascending colon. We describe a patient with upper rectal intussusception caused by a giant rectal lipoma; no similar report of this type of case has been published. PATIENT CONCERNS: We report the case of a patient who suffered from repeated bloody stools. A wide pedicle polyp (size, 6.5 × 4.5 × 3.5 cm) was detected at the 15th centimetre of the anal canal via an electronic colonoscope...

BACKGROUND: Resection of the porto-mesenterico-splenic confluence is at times necessary during pancreatoduodenectomy with portal vein resection for pancreatic cancer. Although splenic vein ligation can cause sinistral portal hypertension, the incidence of clinically relevant sinistral portal hypertension remains unknown, and the roles of the preservation of potential collateral veins and splenic vein reconstruction are controversial. METHODS: Patients with pancreatic cancer who underwent pancreatoduodenectomy with porto-mesenterico-splenic confluence resection were assessed for incidence of development of varices by computed tomography at 6 months after pancreatoduodenectomy...

BACKGROUND AND OBJECTIVES: Tumors of the splenic flexure (TSF) can be associated with metastatic lymph nodes (LN) along the left colic pedicle, but also along the superior mesenteric vessels. We aimed to detail the anatomical distribution of metastatic LNs in patients undergoing elective subtotal colectomy for TSF. METHOD: Between 2000 and 2016, 65 patients were included. At pathological analysis, LNs were classified into two groups: locoregional LN (along the left colic artery) and distant LN (along the middle colic, right colic, and ileocolic arteries)...

AIM: To investigate the vascular anatomy of inferior mesenteric artery (IMA) in laparoscopic radical resection with the preservation of left colic artery (LCA) for rectal cancer. METHODS: A total of 110 patients with rectal cancer who underwent laparoscopic surgical resection with preservation of the LCA were retrospectively reviewed. A 3D vascular reconstruction was performed before each surgical procedure to assess the branches of the IMA. During surgery, the relationship among the IMA, LCA, sigmoid artery (SA) and superior rectal artery (SRA) was evaluated, and the length from the origin of the IMA to the point of branching into the LCA or common trunk of LCA and SA was measured...

Background: The optimal level for inferior mesenteric artery ligation during anterior resection for rectal cancer is controversial. The aim of this randomized trial was to clarify whether the inferior mesenteric artery should be tied at the origin (high tie) or distal to the left colic artery (low tie). Methods: Patients were allocated randomly to undergo either high- or low-tie ligation and were stratified by surgical approach (open or laparoscopic). The primary outcome was the incidence of anastomotic leakage...

BACKGROUND: In rectal anterior resection, a clear consensus regarding the optimal level of inferior mesenteric artery (IMA) ligation does not exist because of a lack of randomized trials. We conducted a randomized trial to determine if the IMA should be tied at the origin (high tie, HT) or distal to the left colic artery (low tie, LT) (HTLT study). This study is a subanalysis of HTLT study for laparoscopic surgery. METHODS: All candidates were randomly divided into the HT or LT groups...

INTRODUCTION: Exact assessment of intestinal viability is necessary, since the risk of anastomotic complications increases due to the reduction in anastomotic blood supply. Near-infrared spectroscopy is useful in assessing blood flow because it allows real-time monitoring and quantifying of tissue oxygen saturation. Herein, we report a case in which two intestinal resections were performed safely by using near-infrared spectroscopy to evaluate the blood flow at the anastomotic sites. PRESENTATION OF CASE: A 67-year-old man was diagnosed with multiple cancers of the transverse colon and rectum...

BACKGROUND: Two ligation techniques can be applied in laparoscopy for left-sided colorectal cancer: (1) high-tie (HT), transection at the level of the inferior mesenteric artery (IMA); and (2) low-tie (LT), transection below the IMA, at the level of superior rectal artery (SRA), preserving the left colic artery (LCA). However, even with preoperative images, it can still be a challenge to identify these structures due to intraoperative individual conditions. In this study, we assess the use intraoperative ultrasonography (IOUS) to aid us in identifying the IMA and its branches to the SRA, LCA, and sigmoid artery...

Xiaohui Du, Xiaowei Xing
With popularity of robotic surgery system, robotic rectal cancer surgery is increasing. Precautionary measures of different perioperative periods should be taken to reduce the risk for anastomotic leakage. First, the general condition of patients should be acquainted and improved, and the risk for anastomotic leakage should be evaluated preoperatively. Preoperative neoadjuvant chemoradiotherapy may not increase the risk for anastomotic leakage after rectal surgery. The impact of routine bowel preparation to prevent anastomotic leakage needs to be verified further...

Controversy remains on how to manage left colic artery (LCA) when it comes to laparoscopic proctectomy. With regard to the level of detachment, a high tie of inferior mesenteric artery (IMA) is meant as a ligation at the origin of aorta, while the low tie is the ligation of IMA below the initiation part of left colic artery which is left. Several key points of LCA preservation, including clinical value, oncologic safety and the difficulty of operation, have always been debated. Some scholars hold the point of view that the preservation of LCA will hamper the lymph nodes dissection around the inferior mesenteric artery, resulting in incorrect pathological staging and dismal outcome...
