Synchronous colorectal neoplasias: our experience about laparoscopic-TEM combined treatment. World J Surg Oncol 2010; 8:105.

Abstract
Synchronous colorectal neoplasias are defined as 2 or more primary tumors identified in the same patient and at the same time. The most voluminous synchronous cancer is called "first primitive" or "index" cancer. The aim of this work is to describe our experience of minimally invasive approach in patients with synchronous colorectal neoplasias.Since January 2001 till December 2009, 557 patients underwent colectomy for colorectal cancer at the Department of General and Emergency Surgery of the University of Perugia; 128 were right colon cancers, 195 were left colon cancers while 234 patients were affected by rectal cancers. We performed 224 laparoscopic colectomies (112 right, 67 left colectomies and 45 anterior resections of rectum), 91 Transanal Endoscopic Microsurgical Excisions (TEM) and 53 Trans Anal Excisions (TAE). In the same observation period 6 patients, 4 males and 2 females, were diagnosed with synchronous colorectal neoplasias. Minimal invasive treatment of colorectal cancer offers the opportunity to treat two different neoplastic lesions at the same time, with a shorter post-operative hospitalization and minor complications. According to our experience, laparoscopy and TEM may ease the treatment of synchronous diseases with a lower morbidity rate.

Abstract
PURPOSE The transanal procedure for rectal cancer surgery is one of the many techniques currently available. Different techniques for local excision of rectal tumors include: conventional transanal technique, posterior access surgery, therapeutic colonoscopy, transanal endoscopic surgery. METHODS The aim of the present study is to describe a new method of transanal endoscopic resection, transanal endoscopic operation (TEO), and performed with the aid of a surgical proctoscope especially designed for this purpose and report the results obtained in 32 patients submitted to the TEO and to compare these results with those obtained with other techniques currently available. The average proportions of recurrence, post-operation complications and posterior resections were analyzed by means of a metanalysis. Data on the distance and size of rectal lesions, the operative timing and hospitalization time were distributed in graphs according to authors and techniques. RESULTS The results were favorable and equivalent to those described in the literature. CONCLUSIONS The surgical proctoscope specially designed for this study is efficient and has a low cost; the TEO is easily performed with the aid of this equipment; the final results were favorable and similar to those obtained with other available techniques for endoscopic transanal intestinal resection, which are of high cost and less availability.

Abstract
Transanal access is one of many currently used procedures for rectal cancer treatment. The techniques used for local excision include conventional transanal excision, posterior access, therapeutic colonoscopy and transanal endoscopic approaches. The aim of the present study was to present a new surgical proctoscope for the endoscopic transanal excision of rectal lesions. A cylindrical proctoscope with a diameter of 4 cm was devised and built. The end inserted into the anus has a bevelled aspect and rounded borders, allowing correct exposure of the anal lesion. The rectoscope is fixed to the anal border with surgical thread through perforations in the external end. A base screw holds a fibre-light which illuminates the operative field. Part of the equipment is a guide which is positioned inside the rectoscope on insertion into the anus. In operations utilizing this proctoscope, 17 adenomas, 25 adenocarcinomas, 1 carcinoid and 1 endometrioma were excised. The diameter of the lesions varied from 1 to 6 cm. The range of procedures that are possible with this new proctoscope are similar to those achieved with conventional techniques which, however, require more expensive equipment. Hence, the present study demonstrates that this newly devised low-cost proctoscope is an efficient tool for the transanal endoscopic excision of rectal lesions.

Abstract
PURPOSE Transanal endoscopic microsurgery (TEM) is a minimally invasive procedure used to transanally excise select benign and malignant tumors of the rectum. In properly selected patients, TEM can provide for decreased postoperative morbidity without compromising oncologic outcome. This report summarizes the recent literature concerning TEM, comprehensively analyzes the authors' experience with TEM, and describes recent technical innovations and indications. PATIENTS AND METHODS Thirty-two consecutive patients scheduled for TEM were identified from our prospectively maintained colorectal service database. Clinicopathologic factors, postoperative complications, and oncologic outcomes were analyzed for all patients. In addition, a PubMed literature search was performed with use of the key words "transanal endoscopic microsurgery," "TEM," "rectal tumor," and "rectal cancer." RESULTS Transanal endoscopic microsurgery was performed for rectal adenocarcinoma (n = 17; 53%), adenoma (n = 12; 38%), and carcinoid tumors (n = 3; 9%). Median tumor location was 9 cm from the anal verge (range, 3-15 cm). Of the 32 attempted TEM procedures, 27 (84%) were completed. Reasons for inability to complete TEM included narrow rectal lumen or contour of bony pelvis prohibiting passage of the operating proctoscope into the upper rectum and inability to maintain the proctoscope in the rectal lumen with carbon dioxide insufflation because of the distal location of the tumor. Innovations used in the excision of rectal tumors via TEM included the use of the harmonic scalpel, closure of the rectal defect with an extracorporeal slip knot, and a hybrid approach incorporating TEM and traditional transanal techniques. CONCLUSION Transanal endoscopic microsurgery provides for low morbidity and does not appear to impair oncologic outcome in properly selected patients.

Abstract
PURPOSE The aim of this study was to systematically review the evidence relating to the safety and efficacy of transanal endoscopic microsurgery, a relatively new technique used to locally excise rectal tumors, compared with existing techniques such as anterior resections and abdominoperineal resections or local excisions. METHODS We conducted a systematic review of comparative studies and case series of transanal endoscopic microsurgery from 1980 to August 2002. RESULTS Three comparative studies (including one randomized, controlled trial) and 55 case series were included. The first area of study was the safety and efficacy of adenomas. In the randomized, controlled trial, no difference could be detected in the rate of early complications between transanal endoscopic microsurgery (10.3 percent) and direct local excision (17 percent) (relative risk, 0.61; 95 percent confidence interval, 0.29-1.29). Transanal endoscopic microsurgery resulted in less local recurrence (6/98; 6 percent) than direct local excision (20/90; 22 percent) (relative risk, 0.28; 95 percent confidence interval, 0.12-0.66). The 6 percent rate of local recurrence for transanal endoscopic microsurgery in this trial is consistent with the rates found in case series of transanal endoscopic microsurgery (median, 5 percent). The second area of study was the safety and efficacy of carcinomas. In the randomized, controlled trial, no difference could be detected in the rate of complications between transanal endoscopic microsurgery and direct local excision (relative risk for overall early complication rates, 0.56; 95 percent confidence interval, 0.22-1.42). No differences in survival or local recurrence rate between transanal endoscopic microsurgery and anterior resection could be detected in either the randomized, controlled trial (hazard ratio,1.02 for survival) or the nonrandomized, comparative study. There were 2 of 25 (8 percent) transanal endoscopic microsurgery recurrences in the randomized, controlled trial, but no figures were given for recurrence after anterior resection. In the case series, the median local recurrence rate for transanal endoscopic microsurgery was 8.4 percent, ranging from 0 percent to 50 percent. The third comparison was cost of the procedures. Transanal endoscopic microsurgery had both a lower recurrence rate and a lower cost than local excision or anterior resection for adenomas. Although the effectiveness of transanal endoscopic microsurgery could not be established for carcinomas, costs were lower than those for either anterior resection or abdominoperineal resection. CONCLUSIONS The evidence regarding transanal endoscopic microsurgery is very limited, being largely based on a single relatively small randomized, controlled trial. However, transanal endoscopic microsurgery does appear to result in fewer recurrences than those with direct local excision in adenomas and thus may be a useful procedure for several small niches of patient types--e.g., for large benign lesions of the middle to upper third of the rectum, for T1 low-risk rectal cancers, and for palliative, not curative, use in more advanced tumors.

Abstract
BACKGROUND The aim of this study is to determine whether gasless, video endoscopic transanal-rectal tumor excision (gasless VTEM) is a valid treatment for rectal carcinoid and laterally spreading tumors (LST). METHODS Eighty-four patients with an adenoma, adenocarcinoma (Tis/T1), or carcinoid tumor of the rectum were divided into three groups: (i) LST ( n = 17 patients), (ii) carcinoid ( n = 11), and (iii) control with other types of tumors ( n = 56). RESULTS The LST group had a longer median operating time than in the control group, whereas the carcinoid group had a shorter operating time. Two patients (11.7%) in LST group developed peritoneal entry during the operation, while 2 patients (3.6%) in the control group experienced postoperative complications. During a median follow-up length of 55.2 months, one patient in the LST group developed a recurrence. CONCLUSIONS Gasless VTEM is a simple, minimally invasive procedure used to treat LST and carcinoid tumors of the rectum. However, resection for the LST group had a high risk of peritoneal entry during operation.

Abstract
Local procedures for carefully selected distal rectal cancer offer significant advantages such as sphincter preservation and avoidance of radical surgery. However, since preoperative selection criteria including current imaging modalities are unable to definitively stage regional lymph node status, local therapies for rectal cancer have the inherent potential disadvantage of undertreating a fraction of patients due to unresected mesorectal/regional lymph node disease. Current available data suggests that the local approach may be appropriate only for carefully selected T1 tumors with favorable pathologic features. Inferior local control and survival reported for T2 tumors and T1 tumors with unfavorable features, despite the addition of chemoradiation, outweigh the advantages of the local approach. Patients with unfavorable tumors who are unable to tolerate radical resection or who refuse surgery may be treated with local excision with or without adjuvant chemoradiation. Other modalities, such as electrocoagulation and endocavitary radiation, may also be valuable in this setting, as well as preoperative chemoradiation followed by local excision. Regardless of the approach used, all patients undergoing local therapy of a rectal cancer require careful long-term follow-up, because these patients remain at significant risk for local recurrence and distant failure.

Abstract
BACKGROUND Transanal endoscopic microsurgery (TEM) is unpopular because of its high cost and most surgeons' unfamiliarity with microscopic surgery. This report describes an experience with a modification of TEM, gasless video endoscopic transanal rectal tumour excision (gasless VTEM), which incorporates a standard laparoscopic video camera and requires no carbon dioxide insufflation system. METHODS One hundred and one patients with 105 rectal tumours underwent gasless VTEM between 1993 and 2000. RESULTS Histological examination revealed 18 adenomas, 75 carcinomas (Tis, 47; T1, 23; T2, five), 11 carcinoid tumours and one lymphoma. The median height above the dentate line and maximum tumour diameter was 5.0 (range 2-14) cm and 2.0 (range 0.4-8.0) cm respectively. The peritoneal cavity was opened intraoperatively in two patients. The median operating time was 53 (range 15-202) min. Bleeding, suture dehiscence and transient incontinence developed after operation in four patients. There was no operative death. Median hospital stay was 5 (range 1-21) days. Eleven patients with T1/T2 staging underwent subsequent radical resection. The median duration of follow-up was 52.3 months. One patient with a carcinoma developed a recurrence. CONCLUSION Gasless VTEM is a feasible, safe and minimally invasive procedure for the treatment of selected rectal adenomas and early carcinomas. The suggested modifications may make the procedure more widely available.
