Abstract
BACKGROUND:
Of the few studies that have investigated quality-of-life (QoL) outcomes after transanal endoscopic microsurgery (TEM), the majority have reported only short-term follow-up data. This study assessed long-term clinical and instrumental outcomes (QoL, sexual, urinary and sphincter function) after TEM for extraperitoneal rectal cancer.
METHODS:
Preoperative and postoperative anorectal function was assessed in consecutive patients with benign rectal lesions or early rectal cancer, based on clinical scores and anorectal manometry.
RESULTS:
Between January 2000 and July 2005, 93 patients undergoing TEM completed the 60-month study protocol. The mean Wexner continence score increased from baseline at 3 months, began to decline within 12 months, and had returned to the preoperative value at 60 months. Urgency was reported by 65·0, 30·0 and 5 per cent of patients at 3, 12 and 60 months respectively (P < 0·050). A significant improvement was noted in various clinical and QoL scores at 12 and 60 months. Postoperative manometry values at 3 months were significantly lower than at baseline (P < 0·050), but had returned to preoperative values at 12 months. Tumour size of 4 cm or above was the only factor that significantly (P = 0·008) affected the rectal sensitivity threshold, the urge to defaecate threshold and the maximum tolerated volume at 3 months after TEM.
CONCLUSION:
TEM had no long-term effect on anorectal function or QoL. Lower anal resting pressure at early follow-up was not associated with defaecation problems in patients who were continent before surgery.

Abstract
Two different ways have been developed to perform endoscopic surgery. The standard way is multiport laparoscopic surgery. When entering through a natural orifice, we use single-port surgery for transanal work (transanal endoscopic microsurgery). In clinical routine, we moved from intralumenal surgery toward surgery in the perirectal area and finally the free abdomen. In the context of natural orifice translumenal endoscopic surgery, we have modified the length and diameter of optics and tube and developed new mechanisms for steering long curved instruments. This technology is then used for transvaginal cholecystectomy and transanal rectosigmoid resection. Global clinical application of transanal endoscopic microsurgery has proven superiority in preciseness and clinical results for adenomas and early cancer. The initial clinical study for transvaginal cholecystectomy is successfully performed in 6 female patients with an average operation time of 80 minutes and without major complication. Feasibility of transanal rectosigmoid resection is demonstrated in an ex vivo experimental model.

Abstract
The knowledge that due to the adenoma-cancer sequence polyps will develop sooner or later into invasive cancer demands the complete removal of colorectal polyps. The majority of polyps can be endoscopically removed. The indications for surgical removal of polyps are a previous incomplete endoscopic resection, location not amenable to endoscopic removal and lesions which are macroscopically highly suspicious for malignancy and cannot be detached by submucosal saline injection. If a surgical approach is indicated minimally invasive surgery in the hands of an experienced laparoscopic surgeon is a suitable option. Adenomas suspicious for malignancy in the lower two thirds of the rectum should not be treated by time-consuming endoscopic submucosal dissection (ESD) and can be quickly and safely removed transanally, conventionally or by transanal endoscopic microsurgery (TEM) by a full thickness én bloc resection. This allows the pathologist to determine the depth of invasion and the completeness of resection in terms of the circumferential margin and a definitive radical surgical approach is only necessary in high risk situations.

Abstract
Colorectal adenomas are frequent and are detected in about 20% of screening colonoscopies. Adenoma resection can be performed endoscopically or surgically. Endoscopic resection techniques include snare polypectomy, endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD). Endoscopic treatment of colorectal adenomas is highly effective and shows acceptable complication rates. After resection of large adenomas the recurrence rate is substantial. However endoscopic retreatment of recurrent events is mostly successful. Considering the minimally invasive nature of endoscopic resections and concerning logistic and economic aspects, endoscopic resection is the treatment of choice for colorectal adenomas.

Abstract
AIM:
Comparison of transanal excision (TE) and transanal endoscopic microsurgery (TEM) of rectal adenomas (RA) has rarely been performed.
METHOD:
From 1990 to 2007, the results of TE (43 RA) and TEM (216 RA) were compared. Rectal adenomas were matched for diameter and distance from the anal verge.
RESULTS:
Operation time was 47.5 min for TE and 35 min for TEM (P < 0.001). Morbidity was 10% after TE and 5.3% after TEM (P < 0.001). Negative resection margins were observed in 50% after TE and 88% after TEM (P < 0.001). Fragmentation of the excised specimen was observed in 23.8% after TE and 1.4% after TEM (P < 0.001). In cases of fragmentation, positive resection margins were observed more frequently. Recurrence was 28.7% after TE and 6.1% after TEM (P < 0.001). After TE, RA with a negative resection margin had a local recurrence rate of 0%, compared with 59.6% with a positive margin (P < 0.001), and after TEM these rates were 3.2 and 7.7% (P = 0.3), respectively.
CONCLUSION:
Transanal endoscopic microsurgery is superior to transanal excision of RA.

Abstract
INTRODUCTION:
Sex reassignment surgery (SRS) can be considered a reasonable and secure treatment for transsexualism, today. Because the population of patients who have received SRS is growing steadily, it can be expected that the number of patients who present with diseases specific to their original gender will increase as well.
AIM:
In female-to-male transsexuals, vaginal cancer has not been reported so far. This article reports, to our knowledge, the first case of a female-to-male transsexual who developed vaginal cancer.
METHODS:
Eighteen years after receiving female-to-male SRS, the patient presented with vaginal cancer, which infiltrated rectum and bladder and also showed involvement of inguinal lymph nodes. Surgery consisted of an anterior and posterior pelvic demolition and extended lymphadenectomy with preservation of the penoid and reconstruction of the pelvic defect with multiple flaps.
RESULTS:
The tumor was removed completely (R0), and 2 years after surgery, the patient has no signs or symptoms of tumor recurrence and enjoys good quality of life.
CONCLUSIONS:
In SRS patients, diseases of their original gender should always be considered and patients should be encouraged to participate in screening programs. When choosing the surgical approach for SRS, the risks for developing cancer from remaining structures of the genetic gender should be considered. Of course, removal of e.g., ovaries, cervix and vagina, will prevent cancer of these structures. When it comes to surgery in SRS patients with malignancies, an interdisciplinary approach should be chosen.
