Abstract
CONTEXT Rectal cancer is common and it is often treated by surgery with or without chemoradiation. Cancer treatment frequently results in bowel symptoms. OBJECTIVES The review aim was to chart the management options for bowel symptoms following rectal cancer surgery. METHODS A scoping review was undertaken searching nine healthcare databases, using relevant search terms and Boolean operators following PRISMA-ScR guidance. Data were extracted into an Excel spreadsheet using headings from the United Kingdom Department of Health guidance and are reported narratively. RESULTS 30 heterogeneous studies met the inclusion criteria, including 853 patients. The most commonly reported bowel symptom was fecal incontinence; the most frequent management strategy was sacral nerve stimulation. Most studies reported on a single management option, often used to manage more than one bowel symptom. Often failure to satisfactorily improve symptoms using options such as medication was needed prior to progressing to other management options. In some studies more than one management option was used, such as rehabilitation programmes. CONCLUSION It is likely that to effectively manage the bowel symptoms experienced after rectal cancer treatment, more than one management option may be used-. Additionally, different management options may need to be tried concurrently.

Abstract
Most pelvic tumors originate from the organs. Less commonly, tumors can arise from the various anatomic pelvic compartments and are comprised of mesenchymal tissue: muscles, connective tissue, vessels, lymphatics, and fat. Among some of the rarer entities are benign tumors (eg, angiomyxoma, cellular angiofibroma, and desmoid fibromatosis), malignant tumors (eg, sarcoma), and tumors that can manifest as benign or malignant (eg, solitary fibrous tumor or nerve sheath tumor). Because these tumors are uncommon and often manifest with nonspecific clinical features, imaging (usually MRI) is an initial step in the evaluation. Radiologists interpreting these images are asked to help narrow the differential diagnosis and assess the likelihood of malignancy for treatment planning. Thus, the MRI report should include the imaging features that would indicate the underlying tissue histology for pathologic diagnosis as well as a description of the anatomic extent and pattern of growth. The authors describe multiple locally aggressive benign and malignant mesenchymal tumors and highlight characteristic clinical and imaging features that enable the radiologist to narrow the differential diagnosis. The anatomic spaces of the pelvis are reviewed with illustrations to aid the radiologist in describing these tumors, which often span multiple pelvic compartments. Tumor appearance at T2-weighted, diffusion-weighted, and postcontrast MRI is summarized and illustrated with correlation at CT or fluorodeoxyglucose PET/CT, when available. MRI features that correspond to specific types of tissue (eg, myxoid, fibrous, or vascular) are highlighted and correlated with images from pathologic evaluation.

Posterior mesorectal thickness as a predictor of increased operative time in rectal cancer surgery: a retrospective cohort study. Surg Endosc 2021; 36:3520-3532. [PMID: 34382121 DOI: 10.1007/s00464-021-08674-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2021] [Accepted: 08/04/2021] [Indexed: 10/20/2022]
Abstract
BACKGROUND In rectal cancer surgery, larger mesorectal fat area has been shown to correlate with increased intraoperative difficulty. Prior studies were mostly in Asian populations with average body mass indices (BMIs) less than 25 kg/m2. This study aimed to define the relationship between radiological variables on pelvic magnetic resonance imaging (MRI) and intraoperative difficulty in a North American population. METHODS This is a single-center retrospective cohort study analyzing all patients who underwent low anterior resection (LAR) or transanal total mesorectal excision (TaTME) for stage I-III rectal adenocarcinoma from January 2015 until December 2019. Eleven pelvic magnetic resonance imaging measures were defined a priori according to previous literature and measured in each of the included patients. Operative time in minutes and intraoperative blood loss in milliliters were utilized as the primary indicators of intraoperative difficulty. RESULTS Eighty-three patients (39.8% female, mean age: 62.4 ± 11.6 years) met inclusion criteria. The mean BMI of included patients was 29.4 ± 6.2 kg/m2. Mean operative times were 227.2 ± 65.1 min and 340.6 ± 78.7 min for LARs and TaTMEs, respectively. On multivariable analysis including patient, tumor, and MRI factors, increasing posterior mesorectal thickness was significantly associated with increased operative time (p = 0.04). Every 1 cm increase in posterior mesorectal thickness correlated with a 26 min and 6 s increase in operative time. None of the MRI measurements correlated strongly with BMI. CONCLUSION As the number of obese rectal cancer patients continues to expand, strategies aimed at optimizing their surgical management are paramount. While increasing BMI is an important preoperative risk factor, the present study identifies posterior mesorectal thickness on MRI as a reliable and easily measurable parameter to help predict operative difficulty. Ultimately, this may in turn serve as an indicator of which patients would benefit most from pre-operative resources aimed at optimizing operative conditions and postoperative recovery.

[PMID: 33248924 DOI: 10.1016/j.surge.2020.09.011] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2020] [Revised: 08/10/2020] [Accepted: 09/02/2020] [Indexed: 12/27/2022]
Abstract
BACKGROUND AND PURPOSE Total Mesorectal Excisions (TME) is the standard treatment of rectal cancer. It can be performed under laparoscopic, robotic or transanal approach. Inadvertent injury to surrounding structure like autonomic nerves is avoidable, no matter which approach is adopted. Lateral lymph node dissection (LLND) is a less commonly performed pelvic operation involving dissection in an unfamiliar area to most general surgeons. This article aims to clarify all the essential anatomy related to these procedures. METHODS We performed thorough literature search and revision on the pelvic anatomy. Our cases of TME and LLND, under either laparoscopic or transanal approach, were reviewed. We integrated the knowledge from literatures and our own experience. The result was presented in details, together with original figures and intra-operative photos. MAIN FINDINGS Anatomy of pelvic fascia, autonomic nerve system, anal canal and sphincter complex are core knowledge in performing TME and LLND. CONCLUSIONS Thorough understanding of the pelvic anatomy enables colorectal surgeons to master these procedures, avoid complication and perform extended resection. On the other hand, surgeons can appreciate the complex pelvic anatomy easier by seeing the pelvis in opposite angles (transabdominal and transaanal view).

Abstract
The primary goal to achieve cure in oncology is to reduce recurrence, maximize disease-free survival, maintain function, and optimize quality of life. Surgery remains the mainstay treatment modality in rectal cancer. The current trend is to perform least invasive method of doing complex surgeries while not compromising in the oncological of functional outcomes of patients. Total mesorectal excision (TME) for rectal cancer surgery entails removal of the rectum with its fascia as an intact unit while preserving surrounding vital structures. The procedure is technically challenging because of the narrow and deep pelvic cavity housing the rectum encased by fatty lymph vascular tissue within the perirectal fascia, distally the anal sphincter complex, and an intimate surrounded by vital structures like ureter, vessels, and nerves. Robotic technology enables overcoming these difficulties caused by complex pelvic anatomy. This system can facilitate better preservation of the pelvic autonomic nerve and thereby achieve favorable postoperative sexual and voiding functions after rectal cancer surgery. The nerve-preserving TME technique includes identification and preservation of the superior hypogastric plexus nerve, bilateral hypogastric nerves, pelvic plexus, and neurovascular bundles.

Abstract
The standard of care for stage T3 and stage T4 rectal adenocarcinomas involves neoadjuvant chemoradiotherapy followed by either low anterior resection or abdominopelvic resection. The presence of residual adenocarcinoma or positive surgical margins provides useful prognostic information and can influence ongoing adjuvant therapy. Although uncommon, mimics of treated adenocarcinoma may be present in the surgical specimen. A high index of suspicion is critical in avoiding potential false-positive pitfalls, and the exclusion of mimics of treated adenocarcinoma is paramount to accurate diagnosis and treatment. Seminal vesicle epithelium has long been a challenge in differentiating prostatic adenocarcinoma from benign epithelium. However, the role of incidental seminal vesiculectomy in rectal resections due to fibrous adhesion to the rectal wall secondary to chemoradiation has not been studied. As the seminal vesicle epithelium can show markedly atypical nuclei with radiation-type effect at baseline, the potential risk of misinterpretation as residual adenocarcinoma is high. In this article, we present 2 case reports of rectal adenocarcinoma treated with neoadjuvant chemoradiotherapy followed by transabdominal resection (low anterior resection or abdominopelvic resection) with incidental seminal vesiculectomies mimicking either residual adenocarcinoma or residual adenocarcinoma at a margin of resection.
