[PMID: 37958469 PMCID: PMC10650459 DOI: 10.3390/cancers15215295] [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: 09/17/2023] [Revised: 10/30/2023] [Accepted: 11/02/2023] [Indexed: 11/15/2023] Open
Abstract
A radical hysterectomy is the standard method of surgical treatment for patients with early-stage cancer of the uterine cervix. It was first introduced more than 100 years ago. Since then, various and many different radical procedures, which diverge in terms of radicality, have been described. Inconsistencies are clearly seen in practical anatomy, which were defined as surgically created artifacts. Moreover, the disparity of the procedure is most notable regarding the terminology of pelvic connective tissues and spaces. Despite these controversies, the procedure is widely performed and implemented in the majority of guidelines for the surgical treatment of cancer of the uterine cervix. However, a different and unique concept of surgical treatment of cervical cancer has been reported. It is based on ontogenetic anatomy and maps any tissue in the mature organism according to its embryologic development. The clinical implementation of this theory in the context of early cervical cancer is total mesometrial resection. The present article aims to describe and compare the anatomical and surgical basics of a radical hysterectomy (type C1/C2) and total mesometrial resection. Discrepancies regarding the terminology, resection lines, and surgical planes of both procedures are highlighted in detail. The surgical anatomy of the pelvic autonomic nerves and its surgical dissection is also delineated. This is the first article that compares the discrepancy of classic anatomy and ontogenic anatomy regarding surgical treatment of cancer of the uterine cervix. Clinical data, oncological outcome, and neoadjuvant and adjuvant treatment regarding both procedures are not the topic of the present article.

Abstract
In recent decades, surgery for rectal cancer has evolved from an operation normally performed under poor vision with a lot of blood loss, relatively high morbidity, and mortality to a safer operation. Currently, minimally invasive rectal procedures are performed with limited blood loss, reduced morbidity, and minimal mortality. The main cause is better knowledge of anatomy and adhering to the principle of operating along embryological planes. Surgery has become surgery of compartments, more so than that of organs. So, rectal cancer surgery has evolved to mesorectal cancer surgery as propagated by Heald and others. The focus on the mesentery of the rectum has led to renewed attention to the anatomy of the fascia surrounding the rectum. Better magnification during laparoscopy and improved optimal three-dimensional (3D) vision during robot-assisted surgery have contributed to the refinement of total mesorectal excision (TME). In this chapter, we describe how to perform a robot-assisted TME with particular attention to the mesentery. Specific points of focus and problem solving are discussed.

Abstract
Controversial surgical anatomical landmarks in the deep pelvis can be visualized and identified using current technologies. Performing the gate approach technique during deep lateral dissection for total mesorectal excision facilitates visualization of the pelvic neurovascular structures following simple dissection steps to preserve the pelvic autonomic nerves and avoid accidental vascular injuries. Here, we discuss laparoscopic exposure of an infrequent disposition of the middle rectal artery anterior to the lateral ligament of the rectum while performing the gate approach.

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
Rectal anatomy is one of the most challenging concepts of visceral anatomy, even though currently there are more than 23,000 papers indexed in PubMed regarding this topic. Nonetheless, even though there is a plethora of information meant to assist clinicians to achieve a better practice, there is no universal understanding of its complexity. This in turn increases the morbidity rates due to iatrogenic causes, as mistakes that could be avoided are repeated. For this reason, this review attempts to gather current knowledge regarding the detailed anatomy of the rectum and to organize and present it in a manner that focuses on its clinical implications, not only for the colorectal surgeon, but most importantly for all colorectal cancer-related specialties.

Abstract
Systematic study of the mesentery is now possible because of clarification of its structure. Although this area of science is in an early phase, important advances have already been made and opportunities uncovered. For example, distinctive anatomical and functional features have been revealed that justify designation of the mesentery as an organ. Accordingly, the mesentery should be subjected to the same investigatory focus that is applied to other organs and systems. In this Review, we summarise the findings of scientific investigations of the mesentery so far and explore its role in human disease. We aim to provide a platform from which to direct future scientific investigation of the human mesentery in health and disease.

Abstract
OBJECTIVE The aim of this study was to express the effects of demographic characteristics, the type of the surgery, tumour characteristics and adjuvant therapy on urinary and sexual dysfunctions. MATERIALS AND METHOD Pre-operational urinary and sexual dysfunctions of the patients were evaluated by using the surveys prepared according to International Prostate Symptom Score (IPSS) and International Index of Erectile Function (IIEF) in men and Index of Female Sexual Function (IFSF) in women. FINDINGS A total of 56 patients were included in the study; 20 of them were women and 36 of them were men. The mean age was 56. Abdominoperineal resection (APR) was performed on 11 patients, and low anterior resection (LAR) was performed on 45. The post-treatment IPSS classes were worsened at a rate of 12.7 % compared to the pre-treatment. The mean post-treatment sexual dysfunction score of both men and women were decreased by 27.5 and 17.8 %, respectively. Rectal tumours located in the lower part resulted in more sexual dysfunction. CONCLUSION The tumour in the 1/3 lower part of the rectal area was determined to be the most effective factor that caused both urinary and sexual dysfunction. Patients should be informed about the urinary and sexual dysfunctions in the pre-operative consultations.

Abstract
In 1986 Professor R J Heald published in The Lancet his new technique which he called Total Mesorectal Excision; today this is the gold standard for the surgical management of rectal cancer. In Total Mesorectal Excision (TME), the mesorectum is the term used to describe all the peri-rectal connective tissue including the posterior sheath of the endopelvic fascia containing the peri-rectal neurovascular structures. However, the mesenterium is a defined structure composed of a double layer of peritoneum which does not include the endopelvic fascia and the lateral rectal stalks, so these should not be included in the term 'mesorectum'. In our globalized medical culture it is important to use anatomic terms approved by the International Federation of Associations of Anatomists, as contained in the Terminologia Anatomica produced by the Federative International Programme for Anatomical Terminology (FIPAT). The term mesorectum is not listed in the Terminologia Anatomica.

Abstract
The double-stapling technique using a circular stapler (CS) to create an end-to-end anastomosis is currently used widely in laparoscopic-assisted rectal surgery. However, a high rate of anastomotic failure has been reported. We report new side-to-side anastomosis creation using a CS, the so-called circular side stapling technique (CST). After excising the rectum at the oral and anal sides of the tumor with a linear stapler, a side-to-side colorectal anastomosis was made on the anterior wall of the rectosigmoid colon and the anterior or posterior wall of the rectum with a CS. Between 2012 and 2013, we recorded 30 serial cases of rectal-sigmoid or rectal cancer that were treated with laparoscopic-assisted surgeries using this method. In the 30 cases, the mean age was 68 ± 12 years, operating time was 288 ± 80 minutes, and blood loss was 66 ± 67 mL. None of the patients suffered from anastomosis leakage or postoperative anastomotic bleeding, and none complained of their stool habits. Three months after the last surgery in this cohort, no anastomosis strictures were reported. Based on these results, we propose an alternative method of side-to-side anastomosis for low anterior resection by using a CS to prevent staple overlap. Our experience indicates that the CST is easy and safe. Therefore, this method is a useful alternative to the current method used in laparoscopic surgery.

Abstract
The ligaments of the rectum have been the subject of controversy for decades. Not only have their contents and components been a source of contention, but also the very existence of these ligaments has been called into question. This article explores the anatomical features of these ligaments with implications for surgical treatment of rectal prolapse, rectal cancer, and resection of the rectum and mesorectum. A theory about the evolution of the lateral rectal ligaments and the mesorectum in humans and higher mammals is also presented.

Abstract
BACKGROUND Efforts to improve approaches to the so called "parametrium" with minimally invasive and less dangerous techniques have led to a better study of the anatomic location and composition of that region. Nevertheless, many misconceptions and confusions about the anatomy of the posterior parametrium and its structures still remain. This study aimed to review anatomic and surgical data and to identify several clear landmarks and surgical steps for a nerve-sparing approach to posterior parametrectomy in the course of radical pelvic surgery with or without rectal resection. METHODS The literature and anatomic dissections of fresh, embalmed, and formalin-fixed female pelvis cadavers were reviewed. The authors' laparotomic and laparoscopic case series also was reviewed for deep-infiltrating endometriosis as well as uterine, ovarian, and rectal cancer. RESULTS The anatomic entity commonly termed the "posterior parametrium" can be identified as the conjunction of three important anatomic structures (ligaments): the cranial structure (uterosacral ligaments), the caudad structure (rectovaginal ligaments), and the laterocaudad structure (lateral rectal ligaments). Identification of these structures (containing autonomic innervations for pelvic viscera) may allow an accurate nerve-sparing surgical approach in many radical pelvic operations. CONCLUSIONS The incidences of urinary, rectal, and sexual morbidity after radical pelvic surgical procedures for oncologic diseases (rectal/ovarian cancer, advanced endometrial/cervical cancer, posterior pelvic recurrences) and deep severe endometriosis can be reduced by better knowing and dissecting the right embryo-anatomic planes of the so-called "posterior parametrium."

Abstract
BACKGROUND Long-term data from the CLASICC study demonstrated the oncologic equivalence of laparoscopic and open rectal cancer surgery despite an increased circumferential resection margin involvement in the laparoscopic group in the initial report. Moreover, laparoscopic total mesorectal excision (TME) may be associated with increased rates of male sexual dysfunction compared to conventional open TME. Robotic surgery could potentially obtain better results than laparoscopy. The aim of this study was to compare the clinical and functional outcomes of robotic and laparoscopic surgery in a single-center experience. METHODS This study was based on 100 patients who underwent minimally invasive anterior rectal resection with TME. Fifty consecutive robotic rectal anterior resections with TME (R-TME) were compared to the first 50 consecutive laparoscopic rectal resections with TME (L-TME). RESULTS Median operative time was 270 min in R-TME and 275 min in L-TME. No conversions occurred in the R-TME group whereas six conversions occurred in the L-TME group. The mean number of harvested lymph nodes was 16.5 ± 7.1 for R-TME and 13.8 ± 6.7 for L-TME. The circumferential margin (CRM) was <2 mm in six L-TME patients, whereas no one in R-TME group had a CRM <2 mm. The International Prostate Symptom Score (IPSS) scores were significantly increased 1 month after surgery in both the L-TME and R-TME groups, but they normalized 1 year after surgery. Erectile function worsened significantly 1 month after surgery in both the groups but it was restored completely 1 year after surgery in the R-TME group and partially in the L-TME group. CONCLUSIONS Robotic TME is oncologically safe and adequate for rectal cancer treatment, showing better results than laparoscopic TME in terms of CRM, conversions, and hospital length of stay. Better recovery in voiding and sexual function is achieved with the robotic technique.

Abstract
BACKGROUND The weight of surgical radicality, together with a lack of anatomical theoretical basis for surgery and inappropriate practical skills, can lead to serious impairments to bladder, rectal, and sexual functions after laparoscopic excision of deep infiltrating endometriosis. Although the "classical" laparoscopic technique for endometriosis excision involving segmental bowel resection has proven to relieve symptoms successfully, it is hampered by several postoperative long-term and/or definitive pelvic dysfunctions. METHODS In this prospective cohort study, we compare the laparoscopic nerve-sparing approach to the classical laparoscopic procedure in a series of 126 cases. Satisfactory data for bowel, bladder, and sexual function were considered as primary endpoints. RESULTS A total of 126 patients were considered for analysis: 61 treated with nerve-sparing radical excision of pelvic endometriosis with segmental bowel resection (group B), and 65 treated with the classical technique (group A). Intraoperative, perioperative, and postoperative complications were similar between the two groups. Mean days of self-catheterization were significantly lower in the nerve-sparing group (39.8 days) compared with the non-nerve-sparing group (121.1 days; p < 0.001). The relapse rate within 12 months after surgery was comparable between the two groups. Patients of group A suffered from urinary retention more frequently between 1 and 6 months (p = 0.035) compared with group B and did not experience any improvement between 6 months and 1 year (p = 0.018). Overall detection of severe bladder/rectal/sexual dysfunctions was significantly different between the two groups, and 56 patients of group A (86.2%) reported a significantly higher rate of severe neurologic pelvic dysfunctions vs. 1 patient (1.6%) of group B (p < 0.001). CONCLUSIONS Our technique appears to be feasible and offers good results in terms of reduced bladder morbidity and apparently higher satisfaction than the classical technique. Considering that this kind of surgery requires uncommon surgical skills and anatomical knowledge, we believe that it should be performed only in selected reference centers.

Abstract
BACKGROUND The significance of magnetic resonance imaging (MRI)-suspected pelvic sidewall (PSW) lymph node involvement in rectal cancer is uncertain. METHODS Magnetic resonance images were reviewed retrospectively by specialist gastrointestinal radiologists for the presence of suspicious PSW nodes. Scans and outcome data were from patients with biopsy-proven rectal cancer and a minimum of 5 years' follow-up in the Magnetic Resonance Imaging and Rectal Cancer European Equivalence Study. Overall disease-free survival (DFS) was analysed using the Kaplan-Meier product-limit method and stratified according to preoperative therapy. Binary logistic regression was used to match patients for propensity of clinical and staging characteristics, and further survival analysis was carried out to determine associations between suspicious PSW nodes on MRI and survival outcomes. RESULTS Of 325 patients, 38 (11·7 per cent) had MRI-identified suspicious PSW nodes on baseline scans. Such nodes were associated with poor outcomes. Five-year DFS was 42 and 70·7 per cent respectively for patients with, and without suspicious PSW nodes (P < 0·001). Among patients undergoing primary surgery, MRI-suspected PSW node involvement was associated with worse 5-year DFS (31 versus 76·3 per cent; P = 0·001), but the presence of suspicious nodes had no impact on survival among patients who received preoperative therapy. After propensity matching for clinical and tumour characteristics, the presence of suspicious PSW nodes on MRI was not an independent prognostic variable. CONCLUSION Patients with suspicious PSW nodes on MRI had significantly worse DFS that appeared improved with the use of preoperative therapy. These nodes were associated with adverse features of the primary tumour and were not an independent prognostic factor.
