BACKGROUND: Colorectal metastases from primary colorectal cancers are very rare, and little is known about their epidemiological aspects or the best diagnostic and therapeutic strategies. Herein, we report a case of a 65-year-old woman with suspected metachronous metastasis to the rectum from primary transverse colon cancer. CASE PRESENTATION: The patient underwent a laparoscopic extended right hemicolectomy for primary transverse colon cancer. Histopathological examination showed moderately differentiated adenocarcinoma, and the tumor was diagnosed as stage IIA (T3, N0, M0)...

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: Anastomotic leakage (AL) is a potential feared complication after colorectal resection, which is associated with an increased risk of postoperative mortality and frequently requires additional surgery. The aim of this study was to assess major independent risk factors for AL after elective colonic resection for cancer, including anastomotic location. METHODS: Among 1940 consecutive patients referred to our institution for colorectal adenocarcinoma, 1025 patients had elective colonic resection with intraperitoneal anastomosis without diverting stoma...

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...

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...

The surgeon dissecting the base of the mesenterium, around the superior mesenteric vein (SMV) and artery, is facing a complex tridimensional vascular anatomy and should be aware of the anatomical variants in this area. The aim of this systematic review is to propose a standardized terminology of the superior mesenteric vessels, with impact in colon and pancreatic resections. We conducted a systematic search in PubMed/MEDLINE and Google Scholar databases up to March 2017. Forty-five studies, involving a total of 6090 specimens were included in the present meta-analysis...

Introduction: Neoplastic invasion of the structures of the cervical region originating from a malignant tumour developed in one of the viscera of the throat may benefit from cervical exenteration. Defined as resection of the hypopharynx, cervical oesophagus, larynx and cervical trachea, exenteration has limited indications and is mandatorily accompanied by digestive tube reconstruction. The aim of this article is to highlight the indication, surgical strategy and important surgical stages illustrated by images from personal professional experience...

We report herein the successful laparoscopic resection of an asymptomatic 3-cm middle colic artery aneurysm in a young woman. Endovascular treatment represents nowadays the first-line option facing visceral artery aneurysm, but in this case, embolization was excluded because of hostile anatomy. Advantages of laparoscopic approach were the safe resection of the aneurysm with immediate evaluation of the bowel tolerance and the possibility of a histological examination of the arterial wall, without the disadvantages of laparotomy...

A 44-year-old woman underwent endoscopic incision of a right simple ureterocele with hydronephrosis discovered during gynecological assessment for stress urinary incontinence with Stage I cystocele. At the postoperative visits, she has reported a persistent flap of mucosa coming out from her urethra protruding in the vagina despite manual reduction. An endoscopic resection of the mucosa flap was programmed. After 24 months, she was asymptomatic with no history of renal colic or urinary tract infection. In patients with a history of pelvic organ prolapse, the resection of the ureterocele in the first instance may be the optimal choice...
