[PMID: 38173914 PMCID: PMC10761226 DOI: 10.1155/2023/6653624] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2023] [Revised: 12/13/2023] [Accepted: 12/18/2023] [Indexed: 01/05/2024] Open
Abstract
Results Incidence of local recurrence was slightly higher in Group A (8.7%) than in Group B (4.3%) but was not statistically significant. There was no statistical significance between both groups regarding distant metastasis (8.7% in Group A and 13% in Group B). Urinary and sexual dysfunctions were higher in Group B (26.1%) compared to those in Group A (21.7%) but were not statistically significant. The incidence of lateral pelvic lymph node metastasis was 30.4%. Also, intraoperative blood loss was higher and operative time was longer in Group B which was statistically significant (P value <0.001). Conclusion Our conclusion was that prophylactic addition of LPLD to TME was not associated with a statistically significant decrease in the risk of local recurrence or distant metastasis in patients with rectal cancer, although it was numerically better. LPLD is associated with longer operative time and higher intraoperative blood loss.

Abstract
PURPOSE Anorectal, sexual, and urinary dysfunction are common issues after rectal cancer surgery, although seldom explored. The primary aim of this study was to investigate postoperative anorectal functional results. METHODS Patients with mid/low-rectal cancer treated with transanal TME (TaTME) with primary anastomosis with/without diverting stoma between 2015 and 2020 were reviewed and selected if they had a minimum follow-up of 6 months (from the primary procedure or stoma reversal). Patients were interviewed using validated questionnaires and the primary outcome was bowel function based on Low Anterior Resection Syndrome (LARS) scores. Statistical analyses were performed to identify clinical/operative variables correlated with worse outcomes. A random forest (RF) algorithm was computed to classify patients at a greater risk of minor/major LARS. RESULTS Ninety-seven patients were selected out of 154 TaTME performed. Overall, 88.7% of the patients had a protective stoma and 25.8% reported major LARS at mean follow-up of 19.0 months. Statistical analyses documented that age, operative time, and interval to stoma reversal correlated with LARS outcomes. The RF analysis disclosed worse LARS symptoms in patients with longer operative time (> 295 min) and stoma reversal interval (> 5.6 months). If the interval ranged between 3 and 5.6 months, older patients (> 65 years) reported worse outcomes. Finally, no statistical difference was documented when comparing the rate of minor/major LARS in the first 27 cases versus others. CONCLUSION One-quarter of the patients developed major LARS after TaTME. An algorithm based on clinical/operative variables, such as age, operative time, and time to stoma reversal, was developed to identify categories at risk for LARS symptoms.

Abstract
Aim To evaluate the efficacy and safety of simple TaTNE in the treatment of low rectal cancer compared with laparoscopic transabdominal TME. Methods We collected patients with low rectal cancer admitted to our hospital between January 2019 and November 2021 who received simple TaTME or laparoscopic transabdominal TME. The main outcome was the integrity of the TME specimen. Secondary outcomes were the number of lymph nodes dissected, intraoperative blood loss, operative time, surgical conversion rate, Specimen resection length, circumferential margin (CRM), and distal resection margin (DRM), complication rate. In addition, the Wexner score and LARS score of fecal incontinence were performed in postoperative follow-up. Results Pathological tissues were successfully resected in all patients. all circumferential margins of the specimen were negative. Specimen resection length was not statistically significant (9.94 ± 2.85 vs. 8.90 ± 2.49, P > 0.05). The incidence of postoperative complications in group A (n = 0) was significantly lower than that in group B (n = 3) (P > 0.05). There was no significant difference in operation time between group A and group B (296 ± 60.36 vs. 305 ± 58.28, P > 0.05). Among the patients with follow-up time less than 1 year, there was no significant difference in Wexner score and LARS score between group A and group B (P > 0.05). However, in patients who were followed up for more than 1 year, the Wexner score in group A (9.25 ± 2.73) was significantly lower than that in group B (17.36 ± 10.95) and was statistically significant (P < 0.05). Conclusion For radical resection of low rectal cancer, Simple TaTME resection may be as safe and effective as laparoscopic transabdominal TME, and the long-term prognosis may be better.

A systematic review and meta-analysis of minimally invasive total mesorectal excision versus transanal total mesorectal excision for mid and low rectal cancer. Front Oncol 2023; 13:1167200. [PMID: 37377919 PMCID: PMC10291686 DOI: 10.3389/fonc.2023.1167200] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2023] [Accepted: 05/10/2023] [Indexed: 06/29/2023] Open
Abstract
Background Minimally invasive total mesorectal excision (MiTME) and transanal total mesorectal excision (TaTME) are popular trends in mid and low rectal cancer. However, there is currently no systematic comparison between MiTME and TaTME of mid and low-rectal cancer. Therefore, we systematically study the perioperative and pathological outcomes of MiTME and TaTME in mid and low rectal cancer. Methods We have searched the Embase, Cochrane Library, PubMed, Medline, and Web of Science for articles on MiTME (robotic or laparoscopic total mesorectal excision) and TaTME (transanal total mesorectal excision). We calculated pooled standard mean difference (SMD), relative risk (RR), and 95% confidence intervals (CIs). The protocol for this review has been registered on PROSPERO (CRD42022374141). Results There are 11010 patients including 39 articles. Compared with TaTME, patients who underwent MiTME had no statistical difference in operation time (SMD -0.14; CI -0.31 to 0.33; I2=84.7%, P=0.116), estimated blood loss (SMD 0.05; CI -0.05 to 0.14; I2=48%, P=0.338), postoperative hospital stay (RR 0.08; CI -0.07 to 0.22; I2=0%, P=0.308), over complications (RR 0.98; CI 0.88 to 1.08; I2=25.4%, P=0.644), intraoperative complications (RR 0.94; CI 0.69 to 1.29; I2=31.1%, P=0.712), postoperative complications (RR 0.98; CI 0.87 to 1.11; I2=16.1%, P=0.789), anastomotic stenosis (RR 0.85; CI 0.73 to 0.98; I2=7.4%, P=0.564), wound infection (RR 1.08; CI 0.65 to 1.81; I2=1.9%, P=0.755), circumferential resection margin (RR 1.10; CI 0.91 to 1.34; I2=0%, P=0.322), distal resection margin (RR 1.49; CI 0.73 to 3.05; I2=0%, P=0.272), major low anterior resection syndrome (RR 0.93; CI 0.79 to 1.10; I2=0%, P=0.386), lymph node yield (SMD 0.06; CI -0.04 to 0.17; I2=39.6%, P=0.249), 2-year DFS rate (RR 0.99; CI 0.88 to 1.11; I2=0%, P = 0.816), 2-year OS rate (RR 1.00; CI 0.90 to 1.11; I2=0%, P = 0.969), distant metastasis rate (RR 0.47; CI 0.17 to 1.29; I2=0%, P = 0.143), and local recurrence rate (RR 1.49; CI 0.75 to 2.97; I2=0%, P = 0.250). However, patients who underwent MiTME had fewer anastomotic leak rates (SMD -0.38; CI -0.59 to -0.17; I2=19.0%, P<0.0001). Conclusion This study comprehensively and systematically evaluated the safety and efficacy of MiTME and TaTME in the treatment of mid to low-rectal cancer through meta-analysis. There is no difference between the two except for patients with MiTME who have a lower anastomotic leakage rate, which provides some evidence-based reference for clinical practice. Of course, in the future, more scientific and rigorous conclusions need to be drawn from multi-center RCT research.

The Quality of Life of Patients with Surgically Treated Colorectal Cancer: A Narrative Review. J Clin Med 2022; 11:jcm11206211. [PMID: 36294531 PMCID: PMC9604858 DOI: 10.3390/jcm11206211] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2022] [Revised: 10/14/2022] [Accepted: 10/18/2022] [Indexed: 11/12/2022] Open
Abstract
INTRODUCTION Quality of life is a topic increasingly being addressed by researchers. Due to the increasing incidence of colorectal cancer, this issue is particularly relevant. Despite the increasing number of publications on this topic each year, it still requires further research. The aim of this study was to analyze the available literature from the past 10 years, addressing the topic of QoL in patients with colorectal cancer which has been treated surgically. MATERIAL AND METHODS This review is based on 93 articles published between 2012 and 2022. It analyzes the impact of socioeconomic factors, the location and stage of the tumor, stoma and the method of surgical treatment on patients' QoL and sexual functioning. RESULTS CRC has a negative impact on patients' financial status, social functioning, pain and physical functioning. Patients with stage II or III cancer have an overall lower QoL than patients with stage I. The more proximally the lesion is located to the sphincters, the greater the negative impact on the QoL. There was a significant difference in favor of laparoscopic surgery compared with open surgery. In patients with a stoma, the QoL is lower compared with patients with preserved gastrointestinal tract continuity. The more time has passed since surgery, the more the presence of a stoma has a negative impact on QoL. Surgery for CRC negatively affects patients' sex lives, especially in younger people and among men. CONCLUSIONS This study may contribute to the identification of the factors that affect the QoL of patients with surgically treated colorectal cancer. This will allow even more effective and complete treatment, facilitating patients' return to normal physical, mental and social functioning.

Abstract
This study constitutes a prospective, three-stage evaluation of quality of life among patients receiving surgical treatment for colorectal cancer depending on the type of surgery performed (open anterior resection, laparoscopic anterior resection, abdominoperineal resection, or Hartmann’s procedure). The study included 82 patients treated at the Surgical Oncology Outpatient Department of the Oncology Center in Bydgoszcz from June 2019 to August 2021. The study tools consisted of diagnostic surveys and analyses of medical records. The standardized study tools were the surveys EORTC QLQ-C30 and QLQ-CR29. In addition, a proprietary questionnaire was developed to collect demographic data. Quality of life was measured at three time-points: the day before the surgery and 6 and 12 months post-surgery. Statistically significant differences (p < 0.05) were observed in the domains of role functioning (III, p = 0.030), body image (II, p < 0.001; III, p < 0.001), sexual functioning (II, p = 0.037), buttocks/anal area/rectum pain (III, p = 0.031), and embarrassment (II, p = 0.022; III, p = 0.010). Statistically significant differences in the functional and symptom scale scores were also observed within each group at different stages of cancer treatment. As shown by our study, the quality of life of patients treated for colorectal cancer is determined not only by the operating technique but also by sociodemographic and clinical factors. The use of minimally invasive surgical techniques enables patients to return to their social roles more quickly and improves their self-assessment of body image.

Preliminary functional results after transanal irrigation in patients undergoing SHiP procedure for low rectal cancer. Updates Surg 2022; 74:1787-1790. [PMID: 35843998 PMCID: PMC9481496 DOI: 10.1007/s13304-022-01334-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2022] [Accepted: 07/06/2022] [Indexed: 11/29/2022]
Abstract
The short-stump and high-anastomosis pull-through procedure (SHiP) is a newly introduced technique in the treatment of rectal cancer. This procedure does not involve the creation of a diverting ostomy with great improvement of the patients’ quality of life in the post-operative period. However, functional post-operative alterations such as low anterior rectal resection syndrome (LARS) may occur. In this context, trans-anal irrigation (TAI) may represent a viable option in the treatment and management of LARS symptoms. The aim of the present study is to investigate the role of TAI in patients operated on SHiP procedure for low rectal cancer. A prospective database of 17 patients who underwent a SHiP procedure was maintained from April 2019 to December 2021. Anal continence and functional outcomes were assessed through LARS score and Cleveland Clinic Incontinence Score (CCIS), respectively. All patients with a LARS score > 21 underwent TAI in the post-operative period. LARS median value was 36 (IQR = 8) and drastically improved after TAI treatment to 3 (IQR = 3), as the CCIS at a mean follow-up of 9 months (SD ± 5.02). Good functional result was reached in 12 out of 13 patients (92%). Our study confirms that patients with severe post-operative dysfunction could benefit from the use of TAI.

Abstract
Objectives: Lower rectal resection is associated with a high rate of postoperative complications and, therefore, adversely impacts the postoperative health-related quality of life (QoL). Though sporadically practiced in different centers, there is no standard perioperative protocol for the management of patients with rectal growths. The aim of this analysis is to evaluate the patient-reported outcomes after low rectal resections followed by an end-to-end-reconstruction and temporary covering ileostomy using a multidisciplinary fail-safe-concept. Methods: Between 2015 and 2020, we evaluated patient reported outcomes after open and laparoscopic rectal resections with end-to-end reconstruction with a primary straight anastomosis using a standardized perioperative pathway All patients with stoma were excluded from the study. The data for the QoL of patients was collected using the established Low Anterior Resection Syndrome (LARS)-score and the EORTC-C30 and CR-29 questionnaires at a single postoperative timepoint. Results: We recruited 78 stoma-free patients for this analysis. Of 78 patients included in the study, 87.2% were operated laparoscopically and the mean global health status was 67.95 points, while a major LARS was detected in 48 (61.5%) patients. No anastomotic leakage (AL) occurred within the study cohort. There was no significant change in the LARS-score or the global health status depending on the follow-up-period. Conclusion: This study shows that good QoL and functional outcomes with no AL are achievable following end-to-end straight anastomosis using a standardized perioperative surgical fail-safe protocol procedure.

Abstract
At inception, transanal total mesorectal excision (TaTME) was hypothesized to be a solution for several problems encountered in pelvic surgery, particularly for distal rectal cancer. The transanal part of the procedure is less hampered by patient related factors such as visceral obesity and a narrow bony pelvis and can thus overcome access and visualization problems encountered with a pure abdominal approach. Clearly, as for any new technique, a learning curve needs to be negotiated, ideally without unacceptable harm to patients. Once in experienced hands, TaTME might overcome challenges found in anatomically challenging rectal cancer patients as well as for other indications. The role of TaTME is not to replace, but rather complement its abdominal counterpart.

Abstract
PURPOSE Rectal cancer is common and is frequently treated with surgery which removes the rectum but retains anal sphincters. After sphincter-saving rectal cancer surgery, which can result in a reduced rectal storage capacity and nerve damage, symptoms frequently occur. METHOD A systematic review was undertaken to determine which symptoms occur and their effect on quality of life. Data from questionnaires and interviews were analysed thematically. RESULTS Fourteen heterogeneous studies were identified reporting both qualitative and quantitative data on over 1700 individuals. The most commonly reported symptoms related to bowel changes. The most problematic changes were bowel and sexual dysfunction. Quality of life was most affected by an inability to function as individuals desired, specifically in their chosen role and socially. Quality of life improved as time progressed or symptoms resolved; but symptoms could persist for many years. CONCLUSION After sphincter-saving rectal cancer surgery quality of life is affected by symptoms such as bowel dysfunction. Healthcare professionals need to gain a better understanding of which symptoms most bother individuals to enable patient-focussed interventions to be planned and improve quality of life.

Abstract
Background: During transanal total mesorectal excision (TaTME), sustained dilation of the anal canal occurs, which can cause anatomical and functional damage to the sphincter complex. This study aimed to analyze the impact of laparoscopic total mesorectal excision (LaTME) and TaTME in anorectal sphincter function. Materials and Methods: An observational study was conducted comparing two cohorts of patients who underwent LaTME or TaTME for rectal cancer. The two groups were paired for comparison based on age, gender, and distance of the neoplasm to the anal margin. The anorectal function was assessed by manometry before surgery and at least 6 months after primary intervention or stoma closure. The intestinal function was assessed using the low anterior resection syndrome (LARS) score. Results: Twenty-two patients were included. There were no significant differences in baseline characteristics between groups except for the time between surgery and testing. A decrease in the mean resting and squeeze pressures between pre- and postoperative manometry was observed in both the treatment groups, the difference being only significant in the squeeze pressure values (TaTME P = .003; LaTME P = .004). After surgery, squeeze pressure reduction correlated with a worsening of the LARS point count (rho 0.587; P = .004). The time elapsed since surgery was negatively correlated with the LARS point count (rho -0.696; P = .001) and the difference between pre- and postoperative mean squeeze pressures (rho -0.499; P = .018). Conclusion: Manometric findings after TME are comparable between the laparoscopic and the transanal approach. Deterioration of both anal sphincter function and LARS improves with time after surgery.

Abstract
Neuro-anatomy of the perineum has gained renewed attention due to its significance in the transanal procedures for rectal cancer (eg TaTME). Surgeons embarking on this technique must have sophisticated knowledge and a precise anatomical understanding of the perineum before proceeding with this reversed rectal approach. We report anatomical observations deriving from a relevant experience in the colorectal surgery field. The collective multicenter experience of the present study is clinically relevant and based on the rectal and transanal resections performed in colorectal centers of excellence from Greece, UK, and Italy over the last 10 years (2011-2020). From the original anatomical and intraoperative observations derived from collective cases operated by this multicenter group of colorectal surgical centers in three European countries, data were retrieved and analyzed in collaboration with specialist researchers of human anatomy and interpreted for their clinical significance and potential use for preoperative planning and intraoperative guidance during TaTME. This descriptive article demonstrates in detail the neurogenic pathways encountered in the perineum and pelvic cavity during transanal procedures. Specific anatomical and topographic implications are also included serving as a guide for colorectal surgeons to perform a nerve-sparing procedure. transanal approach for rectal excision offers new insights into the complex pelvic and perineal neuroanatomy while the procedure itself remains a challenge for surgeons. Preoperative anatomical planning and 3D reconstruction may help in anticipating technical difficulties, resulting in more precise surgical dissections and decreased postoperative complications.

Initial Experience with the Safe Implementation of Transanal Total Mesorectal Excision (TaTME) as a Standardized Procedure for Low Rectal Cancer. J Clin Med 2020; 10:jcm10010072. [PMID: 33379270 PMCID: PMC7795301 DOI: 10.3390/jcm10010072] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2020] [Revised: 12/18/2020] [Accepted: 12/23/2020] [Indexed: 02/07/2023] Open
Abstract
Introduction: The laparoscopic approach for TME is proven to be non-inferior in oncological outcome compared to open surgery. Anatomical limitations in the male and obese pelvis with resulting pathological shortcomings and high conversion rates were stimuli for alternative approaches. The transanal approach for TME (TaTME) was introduced to overcome these limitations. The aim of this study was to evaluate the outcomes of TaTME for mid and low rectal cancer at our center. Methods: TaTME is a hybrid procedure of simultaneously laparoscopic and transanal mesorectal excision. A retrospective analysis of all consecutive TaTME procedures performed at our center for mid and low rectal cancer between December 2014 and January 2020 was conducted. Results: A total of 157 patients underwent TaTME, with 72.6% receiving neoadjuvant chemoradiation. Mean tumor height was 6.1 ± 2.3 cm from the anal verge, 72.6% of patients had undergone neoadjuvant chemoradiotherapy, and 34.2% of patients presented with a threatened CRM upon pretherapeutic MRI. Abdominal conversion rate was 5.7% with no conversion for the transanal dissection. Early anastomotic leakage occurred in 7.0% of the patients. Mesorectum specimen was complete in 87.3%, R1 resection rate was 4.5% (involved distal resection margin) and in 7.6%, the CRM was positive. The three-year local recurrence rate of 58 patients with a follow-up ≥ 36 months was 3.4%. Overall survival was 92.0% after 12 months, and 82.2% after 36 months. Conclusion: TaTME can be performed safely with acceptable long-term oncological outcome. Low rectal cancer can be well addressed by TaTME, which is an appropriate alternative with low conversion, local recurrence, adequate mesorectal quality and CRM positivity rates.
