Trans‑anal minimally invasive surgery (TAMIS) versus rigid platforms for local excision of early rectal cancer: a systematic review and meta-analysis of the literature. Surg Endosc 2024; 38:4198-4206. [PMID: 39026004 PMCID: PMC11289048 DOI: 10.1007/s00464-024-11065-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2024] [Accepted: 07/06/2024] [Indexed: 07/20/2024]
Abstract
BACKGROUND Available platforms for local excision (LE) of early rectal cancer are rigid or flexible [trans‑anal minimally invasive surgery (TAMIS)]. We systematically searched the literature to compare outcomes between platforms. METHODS PRISMA-compliant search of PubMed and Scopus databases until September 2022 was undertaken in this random-effect meta-analysis. Statistical heterogeneity was assessed using I2 statistic. Studies comparing TAMIS versus rigid platforms for LE for early rectal cancer were included. Main outcome measures were intraoperative and short-term postoperative outcomes and specimen quality. RESULTS 7 studies were published between 2015 and 2022, including 931 patients (423 females); 402 underwent TAMIS and 529 underwent LE with rigid platforms. Techniques were similar for operative time (WMD 11.1, 95%CI - 2.6 to 25, p = 0.11), percentage of defect closure (OR 0.7, 95%CI 0.06-8.22, p = 0.78), and peritoneal violation (OR 0.41, 95%CI 0.12-1.43, p = 0.16). Rigid platforms had higher rates of short-term complications (19.1% vs 14.2, OR 1.6, 95%CI 1.07-2.4, p = 0.02), although no significant differences were seen for major complications (OR 1.41, 95%CI 0.61-3.23, p = 0.41). Patients in the rigid platforms group were 3-times more likely to be re-admitted within 30 days compared to the TAMIS group (OR 3.1, 95%CI 1.07-9.4, p = 0.03). Rates of positive resection margins (rigid platforms: 7.6% vs TAMIS: 9.34%, OR 0.81, 95%CI 0.42-1.55, p = 0.53) and specimen fragmentation (rigid platforms: 3.3% vs TAMIS: 4.4%, OR 0.74, 95%CI 0.33-1.64, p = 0.46) were similar between the groups. Salvage surgery was required in 5.5% of rigid platform patients and 6.2% of TAMIS patients (OR 0.8, 95%CI 0.4-1.8, p = 0.7). CONCLUSION TAMIS or rigid platforms for LE seem to have similar operative outcomes and specimen quality. The TAMIS group demonstrated lower readmission and overall complication rates but did not significantly differ for major complications. The choice of platform should be based on availability, cost, and surgeon's preference.

[PMID: 37170198 PMCID: PMC10176938 DOI: 10.1186/s12909-023-04296-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/28/2022] [Accepted: 04/23/2023] [Indexed: 05/13/2023]
Abstract
BACKGROUND The objective of our study is to develop an effective training platform for transanal endoscopic surgery and to validate a step-by-step training program for learning the basic skills necessary for this approach. METHODS We have designed a two-part study: an experimental study (with the aim to design the training platform and the training exercises - on synthetic and biological material) and a prospective analytical study, in order to validate the training program by enrolling as participants general surgery residents and specialists, without previous experience in transanal endoscopic interventions. The performance of the participants was assessed based on the time of completion, as well as the quality of the execution. RESULTS We have developed three different diameter platforms (5 cm, 7.5 and 10 cm), that can be used with both the TEO and TAMIS platforms; specific exercises were developed to train different surgical skills like manipulation of tissue, cutting, dissection and suturing. Forty participants were enrolled for the validation of the proposed training program (12 young residents, 16 senior residents and 12 specialist surgeons). A statistically significant improvement of the performance time, from round to round, was observed for all participants in all exercises. The time of completion for the exercises, considering the correct technical execution, was the shortest for more experienced surgeons: specialist surgeons, followed by senior residents and young residents. The biological material exercises, that closely recreate intraoperative conditions and had more strict technical requirements, were difficult to be performed by young residents; better completion rates were seen in senior residents, while all the participants in the specialist surgeons group have completed these exercises. CONCLUSIONS Our training program is an effective simulation based educational model for recreating intraoperative conditions particular to transanal endoscopic surgery. The proposed step-by-step training program has demonstrated to be useful in developing the important basic skills needed for transanal endoscopic surgery and assured the progress of all the participants, regardless of their surgical experience.

Abstract
Transanal endoscopic surgery (TES) was introduced in the 1980s, but more widely adopted in the late 2000s with innovations in instrumentation and training. Moreover, the global adoption of minimally invasive approaches to abdominal procedures has led to translatable skills for TES among colorectal and general surgeons. While there are similarities to laparoscopic surgery, TES has unique challenges related to the narrow confines of intraluminal surgery, angled instrumentation, and relatively uncommon indications limiting the opportunity to practice. The following review discusses the current evidence on TES learning curves, including potential limitations related to the broad adoption of TES by general surgeons. This article aims to provide general recommendations for the safe expansion of TES.

Abstract
Transanal endoscopic surgery encompasses the minimally invasive surgical techniques used to operate in the rectum under magnification while maintaining pneumorectum via a resectoscope or port. The view, magnification, and surgical precision afforded by these advanced transanal techniques have resulted in excellent specimen quality and low recurrence rates, especially compared with traditional transanal surgery. For rigid platforms, the surgeon operates through a rigid 4-cm diameter steel proctoscope of varying lengths that is clamped to the operating table with an articulating arm. Transanal minimally invasive surgery (TAMIS) is a newer flexible platform using a disposable port which "hooks" into the anorectal ring to remain in place. The cost-effectiveness and versatility of the TAMIS platform have resulted in its popularity and use in more advanced applications such as transanal total mesorectal excision. Ultimately, the choice of operating platform should be based on surgeon preference, patient characteristics, availability, and cost. The pros and cons of each platform will be discussed in this article.

Abstract
PURPOSE This study presents the surgical and postoperative results achieved with a rigid proctoscope using the transanal endoscopic technique to excise rectal adenomas. The results are compared to the results obtained with other currently employed transanal techniques. METHODS We investigated the medical records of patients who underwent transanal endoscopic operations from April 2000 to June 2018 at two tertiary referral centers for colorectal cancer. RESULTS This study included 99 patients. The mean age was 65.3 ± 13.3 years. The average size of the adenomas was 4.6 ± 2.3 cm, and their average distance to the anal border was 5.6 ± 3.3 cm. The average operative time was 65.3 ± 41.7 min. In 48.5% of the operations, the specimen was fragmented, and in 59.6% of the cases, the microscopic margins were free. The rates of postoperative complications and relapse were 5% and 19%, respectively. The mean follow-up was 80 ± 61.5 months. CONCLUSIONS The described proctoscope proved to be a viable technique with results similar to other techniques, with the advantage that it allowed greater accessibility for surgeons. Therefore, its use could be implemented and become widespread in surgical practice.

Abstract
AIM Transanal endoscopic microsurgery (TEM) is the current treatment of choice for rectal adenomas and early rectal cancer. Postoperative admission to hospital is common but possibly unnecessary. Our objective was to analyse predictors and outcomes of TEM patients having same day discharge (TEM-D) compared with those who were admitted to hospital (TEM-A). METHOD At St Paul's Hospital (SPH), demographic, surgical, pathological and follow-up data have been collected prospectively since TEM was started in 2007. Trends in admission and readmission rates were analysed using the Cochran-Armitage trend test, and predictors of admission were analysed using univariate and multivariate logistic regressions. RESULTS Between 2007 and 2016, 500 patients were treated by TEM at SPH. The overall admission rate was 29% (145/500), but this decreased to 19% in the last 3 years of the study (P < 0.001). The readmission rate was 5.2% (n = 26/500) and did not change significantly over the study period (P = 0.30). Reasons for admission included the following: surgeon discretion/monitoring (35%), urinary retention (26%), haemorrhage (10%), breach of peritoneal cavity (7%), infection (7%) and other (15%). The most common reasons for readmission were haemorrhage (54%, n = 14), pain (19%, n = 5) and infection (12%, n = 3). Factors associated with admission were as follows: tumour height (OR 1.09, 1.02-1.17), prolonged operative time (OR 1.25, 1.14-1.37), unsutured surgical defect (OR 1.99, 1.22-3.25) and surgeon experience (OR 4.62, 2.75-7.77). CONCLUSION Outpatient TEM is safe and carries a low risk of readmission. In centres with an outpatient TEM strategy, predictors of hospital admission include proximal tumours, prolonged surgical time and open management of the surgical defect.

Abstract
Background Trans-anal endoscopic operation (TEO) has developed to facilitate proper tumor location and ensure excision safely. Methods We reviewed 92 patients enrolled in our database between 2006 and 2014 who were diagnosed with early rectal tumors and who underwent conventional trans-anal excision (TAE) or TEO. Clinical data were collected prospectively to compare safety and feasibility between two techniques. Results Ninety-two patients underwent trans-anal local excision for lower rectal tumors. TEO and TAE were performed in 48 and 44 patients, respectively. Age, sex, and comorbidities were similar. There was no significant difference in tumor diameter (1.6 ± 1.68 cm vs. 1.17 ± 1.17, respectively). Tumor height, however, was higher in the TEO (7.46 ± 3 cm) than the TAE group (3.84 ± 1.88 cm, p < 0.001). Four complications, perianal abscess, and two perforations, occurred in the TEO group, whereas no major complications occurred in the TAE. Seven patients (14.6%) underwent TEO underwent a salvage operation compared to only a single patient in TAE group (2.3%, p = 0.039). Eight patients (17.4%) diagnosed with adenocarcinoma developed recurrence, four in each group. Disease-free survival was similar between groups (TEO – 41.8 months, 95% RI 39.4–44.1; TAE 79.7 months, 95% RI 72.2–87.3). However, more TAE patients (n = 7, 15.9%) than TEO patients (n = 2, 4.2%) underwent chemotherapy. Conclusions TEO treatment of local rectal tumors is safe and feasible and can achieve an adequate resection margin. Local recurrence was similar in both groups. However, the numbers of salvage operations and minor complications were higher in the TEO group. TEO is treatment modality of choice in addressing lower rectal lesions. Evolving of TEO technique facilitate higher standard of academic teaching. TEO has few drawbacks; first, long term learning curve; second, technique is demanding (through single port + narrow space). TEO has promising results in the field of surgical oncology with equivalent results to conventional surgery.
