AIM: To describe the technique of a modified extraperitoneal retrotransversalis end colostomy as part of a laparoscopic abdomino-perineal resection (APR). METHOD: The colostomy site is preoperatively chosen and intraoperatively used for a trocar. After the rectum has been mobilized the descending colon is freed. The peritoneal margin is gently grasped and the parietal peritoneum, extraperitoneal together with the transversalis fascia are separated from the transverse abdominal muscle fibres upwards for 3-4 cm aiming at the trocar site to form the extraperitoneal retrotransversalis canal...

INTRODUCTION: Nowadays, after wide left colectomy, it is necessary to choose one of the following procedures: a definitive transverse colostomy, an ileo-rectal anastomosis or a right colo-rectal anastomosis (Deloyers procedure). PRESENTATION OF CASE: We performed our new procedure on a 63 years-old man. After an extensive left proctocolectomy, the intestinal continuity between the transverse colon and rectum was obtained by transposition and rotation of the right colon into the pelvis...

AIM: The Low Anterior Resection Syndrome (LARS) severely affects quality of life (QoL) after rectal cancer surgery. There are no data about functional complaints after sigmoid cancer surgery. We investigated LARS and QoL in patients with a resection for sigmoid cancer versus patients who had surgery for rectal cancer. METHODS: 506 patients after resection for rectal or sigmoid cancer who were at least one year colostomy-free were included between January 2008 and December 2013...

BACKGROUND: Studies suggest that defunctioning stomas reduce the rate of anastomotic leakage and urgent reoperations after anterior resection. Although the magnitude of benefit appears to be limited, there has been a trend in recent years towards routinely creating defunctioning stomas. However, little is known about post-operative complication rates in patients with and without a defunctioning stoma. We compared overall short-term post-operative complications after low anterior resection in patients managed with a defunctioning stoma to those managed without a stoma...

An 84-year-old man presented in 2009 with a sensation of discomfort in his anus, combined with difficulty in urination. He had previously undergone a haemorrhoidectomy in 1964. After examination, he was diagnosed with a rectal mucosal cyst and followed up for observation. In 2015, he presented to our hospital complaining that the cyst was prolapsing from his anus. CT revealed a 48×41 mm cystic mass in the anterior wall of the rectum. Tumour extirpation, via a transanal route, was performed. The postoperative pathological diagnosis confirmed a rectal mucocele...

Brachytherapy has known major improvements in recent decades. It represents an essential component of local treatment of cervix cancers. One major breakthrough was the advent of 3D imaging for image-guided brachytherapy. Doses could be prescribed to volumes. This allows better delineation and coverage of target volumes, as well as organs at risk (bladder, rectum, sigmoid) protection. Local recurrences have been consequently reduced and survival has been improved. In addition, improvement and development of new applicators have facilitated the delivery of interstitial treatments...

A 15-year-old adolescent boy presented with chronic constipation, difficulty in defecation, and episodic bloody stools. A rectal mass lesion was digitally palpated. Colonoscopy showed a large circumferential polypoid lesion of the mid-rectum. Snare polypectomy was performed, and histopathology confirmed a diagnosis of benign inflammatory cap polyposis. At 3-month follow-up, sigmoidoscopy showed multiple recurrences of polyps at the site of the previous rectal polypectomy, which were removed by combined hot snare polypectomy and argon plasma coagulation...

BACKGROUND: National databases show a recent significant increase in the incidence of colorectal cancer in people younger than 50. With current recommendations to begin average-risk screening at age 50, these patients do not have the opportunity to be screened. We hypothesized that most of the cancers among the young would be left sided, which would create an opportunity for screening the young by flexible sigmoidoscopy. OBJECTIVE: This study aims to analyze the anatomic distribution of sporadic colorectal cancers in patients under the age of 50...

BACKGROUND: Radical resection by multivisceral resection of colorectal T4 tumours is important to reduce local recurrence and improve survival. Oncological safety of laparoscopic resection of T4 tumours is controversial. However, robot-assisted resections might have advantages, such as 3D view and greater range of motion of instruments. The aim of this study is to evaluate the initial results of robot-assisted resection of T4 rectal and distal sigmoid tumours. METHODS: This is a cohort study of a prospectively kept database of all robot-assisted rectal and sigmoid resections between 2012 and 2017...

Background: Polyarteritis nodosa (PAN) is a vasculitis that affects medium sized arteries. PAN is a rare disease and requires a high vilgilance for diagnosis. For instance, PAN and Henoch-Schonlein purpura (HSP) have narrowing differential diagnosis. Here, we report a case of PAN. Case presentation : Our patient was a 65 year old woman that came to hospital due to abdominal pain and skin lesion on the right upper and right lower extremities. All rheumatologic tests were negative. A biopsy of the skin lesion was reported as mild hyperkeratosis, slight spongiosis with intact basal layer...

BACKGROUND: Prospective trials have demonstrated the advantage of dose-escalated radiotherapy for the biochemical and clinical control of intermediate risk prostate cancer. Dose escalation improves outcomes but increases risks of urinary and bowel toxicity. Recently the contribution of "spacers" positioned in the septum between the rectum and the prostate could improve the functional results of intensity modulated radiation therapy (IMRT). To date most of the evaluated devices were polyethylen glycol (PEG) and hyaluronic acid (HA)...

PURPOSE: Although a minimum of 12 lymph nodes (LNs) has been recommended for colorectal cancer, there remains considerable debates for rectal cancer patients. Inadequacy of examined LNs would lead to under-staging, and inappropriate treatment as a consequence. We describe statistical tool that allows an estimate the probability of false-negative nodes. METHODS: A total of 26,778 adenocarcinoma rectum cancer patients with tumour stage (T stage) 1-3, diagnosed between 2004 and 2013, who did not receive neoadjuvant therapies and had at least one histologically assessed LN, were extracted from the Surveillance, Epidemiology and End Results (SEER) database...

INTRODUCTION: Rectal duplication cysts are rare cystic lesions, arising from the hindgut and classified as congenital/developmental tumors of the presacral space. Their clinical presentation is nonspecific, the diagnosis remains difficult and their management is aided by a multidisciplinary evaluation. CASE REPORT: We report the case of a 55-year-old woman with a cystic mass located in the retrorectal space and identified incidentally on a CT scan. Following imaging studies, surgical resection by a posterior approach (Kraske procedure) was carried out and an adenocarcinoma arising in a duplication cyst of the rectum was present an uncommon case of a rectal duplication cyst with malignant transformation and distant metastasis, describe the clinical, radiologic and pathologic findings and discuss tidentified by microscopy...

PURPOSE: To compare CT- and MRI-based brachytherapy (BT) target volumes for patients with advanced cervical cancer so as to identify those who benefit most from MRI-based planning. We also studied how the natural mobility of the organ at risks (OARs) affects the given doses. METHODS AND MATERIALS: Subjects were 60 patients with International Federation of Gynecology and Obstetrics (FIGO) Stage IB-IVA cervical cancer. The CT high-risk clinical target volume (HR-CTV) was first delineated, then the MRI HR-CTV, with volume discrepancies calculated by subtraction...
