Abstract
A case of tubulovillous adenoma arising in an augmented bladder is described. Ureteroileal substitution and ileocystoplasty was performed when the patient was 18 years old. She noticed gross hematuria 44 years after the surgery. Cystoscopy revealed a non-papillary multiple tumor at the site of ileovesical anastomosis and transurethral resection biopsy was performed. Histopathological examination revealed a tubulovillous adenoma. A tubulovillous adenoma developing at the augmented bladder is rare. To our knowledge, this is the second case in which a tubulovillous adenoma developed in an augmented bladder.

Abstract
AIMS Pseudomyxoma peritonei may have as its primary site a mucinous gastrointestinal adenoma or carcinoma that gains access to the peritoneal cavity. This manuscript describes this disease arising from a benign or malignant colonic polyp. METHODS From a database of over 1000 pseudomyxoma peritonei patients and colorectal carcinomatosis patients, three cases were identified in which the primary tumor site was a colonic polyp. The clinical history and course of these patients were studied. RESULTS In a review of the clinical management of these patients, all three had an event whereby neoplastic cells from the surface of the colonic polyp could have gained access to the free peritoneal cavity. The patients developed the characteristic pseudomyxoma peritonei syndrome. All three patients were treated with cytoreductive surgery plus perioperative hyperthermic intraperitoneal chemotherapy. CONCLUSIONS Colonic polyps can serve as a source of dysplastic cells whereby pseudomyxoma peritonei can result. Caution to prevent seeding to the free peritoneal cavity during surgery for colonic polyps should be observed. If pseudomyxoma peritonei develops, cytoreductive surgery and perioperative intraperitoneal chemotherapy should be considered for treatment.

Abstract
Villous adenomas of the duodenum (VAD) are infrequent lesions of the gastrointestinal tract but have a high risk of recurrence and malignancy. For these reasons and its specific topographic location, the surgical treatment of VAD is still controversial. Herein we present a case of large VAD located in the second duodenal portion that was successfully treated with a head of the pancreas, pylorus-preserving total duodenectomy (PPTD). PPTD should be an excellent option in patients with large adenomas because it allows preservation of the pancreas, gastrointestinal function is maintained, the possibility of a recurrence and of an invasive carcinoma of the ampulla is eliminated, and finally because it permits an adequate endoscopic follow-up. PPTD should not be used in the presence of malignancy and/or high-grade dysplasia.

Abstract
BACKGROUND Epithelial tumors of the papilla of Vater are rare neoplasms of the gastrointestinal tract. The carcinogenesis of these tumors seems to be fairly analogous to the genetic mechanisms which have been described for colorectal carcinoma. Patients with familial adenomatous polyposis bear a particularly increased risk for periampullary tumors. Data on whether the prevalence of colorectal tumors is increased in patients with sporadic ampullary neoplasms are scarce. METHODS 26 consecutive patients (16 women, 10 men; median age 59 years) with sporadic adenomas (n = 19) or adenocarcinomas (n = 7) of the ampulla of Vater were retrospectively evaluated. The study patients were compared with 104 age-matched asymptomatic controls. All patients had undergone total colonoscopy. RESULTS Neoplastic colorectal polyps were present in a similar proportion (23%) of patients of the study group compared with 26% in the control group (p > 0.05). Overall, 16 polyps were found among patients with ampullary tumors and 40 in asymptomatic controls (p > 0.05). Colonoscopy detected rectal carcinoma in 2 patients (8%) of the study group. Patients with and without colorectal polyps differed neither significantly by age nor by ampullary histological findings. 50% of the colonic polyps in patients with ampullary neoplasms were located in the ascending colon. CONCLUSIONS The frequency of colorectal polyps in patients with ampullary tumors did not exceed the risk in the control group. However, the finding of 2 rectal carcinomas among patients with ampullary neoplasms supports the place of screening colonoscopy for the diagnostic work-up of ampullary tumors. Prospective multicenter studies should address this issue to provide a broad basis for future recommendations.

Abstract
PURPOSE Intersphincteric resection of low rectal tumors is a surgical technique extending rectal resection into the intersphincteric space. This procedure is performed by a synchronous abdominoperineal approach with mesorectal excision and excision of the entire or part of the internal sphincter. This study was designed to evaluate the long-term results of this method focused on continence function and oncologic results. METHODS From 1984 to 2000, a total of 121 patients were operated on. The patients were evaluated prospectively according to a detailed preoperative and postoperative program. RESULTS One hundred seventeen patients had rectal cancers, two had dysplastic villous adenomas, and two had carcinoid tumors. Cancers were staged according to the Dukes classification (Stage A in 41 percent, Stage B in 28 percent, and Stage C in 31 percent; median distance from the anal margin, 3 (range, 1-5) cm). Postoperative complications were: one death because of pulmonary embolism, 5.1 percent developed an anastomotic fistula, one patient had a fistula to the bladder requiring reoperation, one patient with ileus needed relaparotomy as well as one for intra-abdominal hemorrhage and a small-bowel fistula. One patient developed a fistula after closing the protective colostomy. Five patients developed late strictures of the coloanal anastomosis. After a median follow-up of 72.86 months, 5.3 percent of patients developed local recurrence. The continence status was satisfactory with 16 patients (13.7 percent) showing continence for solid stool only, and 1 patient (0.8 percent) showing episodes of incontinence. A transient problem was a high stool frequency after closure of the protective stoma. CONCLUSIONS Intersphincteric resection is a valuable procedure for sphincter-saving rectal surgery. We showed that this technique has satisfactory long-term results in functional and oncologic respects. An important prerequisite is a careful preoperative evaluation of local tumor spread with rectal magnetic resonance imaging excluding infiltration of the external sphincter.

Abstract
Most colonic polyps are asymptomatic and the incidence rises during sixth and seventh decades. Symptoms and signs may vary with histological types and location. Clinical features include fresh rectal bleeding, mucoid diarrhea and prolapsus of stalked rectal polyps located near distal segment. Here we discuss a case with a rare clinical presentation, who had sessile malign villous adenoma located in the descending colon, which caused colocolic intussusception and prolapsed through the anus.

Abstract
INTRODUCTION Endoscopic mucosal resection is a safe resection tool for selected flat, sessile and lateral spreading tumours of the colon. Transanal microsurgical resection of select rectal neoplastic lesions is another accepted modality. Recent data suggests transanal microsurgery may have high complication rates. We conducted a prospective clinicopathological evaluation of an extended endoscopic mucosal resection technique for highly selected lesions of the rectum and assessed outcome data over a maximal 24-month period. PATIENTS AND METHODS Eighty-three patients with known rectal neoplastic lesions underwent chromoscopic colonoscopy and on-table staging using a high-frequency (12.5 MHz) mini-probe EUS by a single endoscopist. Patients with T2 or node positive disease were referred for surgery. Following extended endoscopic mucosal resection patients were followed-up at 3, 6, 12 and 24 months post 'index' resection with chromoscopic endoscopy and EUS. Procedural complications, recurrence rates and outcome data were collected. RESULTS Sixty-two patients fulfilled inclusion criteria. Median procedure time was 48 mins (range 32-126). Lateral spreading tumours (median diameter 30 mm; range 18-42 mm) and sessile lesions (median diameter 38 mm; range 25-86 mm) accounted for 19% and 81% of lesions, respectively. Ninety-seven percent of patients undergoing EMR were discharged within 6-h of procedure. Thirty-day re-admission and death rate was 0%. Bleeding complications occurred in 5/62 (8%) of patients with all achieving complete haemostasis using endo clips. None required transfusion. There were no procedural related complications or perforations. Overall 'cure' rate at a median follow-up of 16 months was 98%. CONCLUSIONS Extended endoscopic mucosal resection for rectal neoplastic lesions can achieve superior results to those of per-anal excision and trans-anal microsurgery with regard to complications and recurrence rates. Extended endoscopic mucosal resection may be an alternative therapeutic modality in selected patients.

Abstract
INTRODUCTION Adenomas are the most frequent tumors of the Vater s ampulla. Their capacity for malignant transformation following the adenoma-carcinoma sequence is well known. It is because of this that resection after diagnosis is required. The identification of the appropriate technique according to tumor features would require that patients not be undertreated or overtreated, which would give rise to serious consequences derived from their location. PATIENTS AND METHODS Villous adenomas and adenocarcinomas of the Vater s ampulla candidates for local resection were revised from January 1st, 1998 through June 30th, 2003. We describe the methods of diagnosis and ampulectomy techniques we performed. RESULTS We performed an ampulectomy by first intention in all 8 patients included in this study. However, pancreatoduodenectomy was necessary in two patients because of the closeness of resection margins. We had no mortality in this series, and morbidity was limited to two episodes of digestive bleeding that were controlled by electrocoagulation and embolization. The mean follow-up was 28.5 months (range, 6-72 months). CONCLUSIONS The difficulty of precise preoperatory diagnosis in adenomas of the Vater s ampulla demands resection after identification. Ampulectomy is the treatment of choice for villous adenomas and T1 adenocarcinomas, with 1 cm of resection margin to avoid local recurrence.

Abstract
We describe a successful simultaneous laparoscopic treatment of a gallstone and gastric and colonic neoplasms. The patient was a 72-year-old man with epigastric discomfort. Abdominal ultrasound revealed a gallstone 2 cm in diameter. Gastroscopy revealed a 3-cm protruding submucosal tumor in the gastric fundus and colonoscopy revealed a 2-cm sessile lesion in the sigmoid colon. He underwent simultaneous laparoscopic treatment of the 3 organs because of the high risk of perforation or bleeding after gastric or colonic resection. This required the use of 5 ports, and a 3.5-cm incision was made in the left lower quadrant to access the 3 organs. The laparoscopic procedures consisted of cholecystectomy, partial stapled resection of the gastric fundus, and partial resection of the sigmoid colon. The histopathologic diagnoses were chronic cholecystitis, leiomyoma of the stomach, and tubulovillous adenoma with severe dysplasia of the colon. The operation took 183 minutes and blood loss was minimal. The patient started oral intake from the second postoperative day and was discharged uneventfully. He had from no postoperative complications or abdominal symptoms during a 15-month follow-up period. To our knowledge, this is a first successful clinical report of simultaneous laparoscopic treatment of 3 organ disorders.

Abstract
PATIENT AND METHODS A 68-year-old woman presenting with bloody stools and anemia was referred to our hospital. Colonoscopy showed a Is-type tumor of 45 mm in diameter in the cecum and three Is-type tumors in the ascending colon. Ileocecal resection with regional lymph node dissection was performed. Microscopically, the large tumor consisted of a well-differentiated adenocarcinoma with a tubulovillous adenoma (TVA) component (carcinoma in adenoma). Some carcinoma (CA) cells had invaded the submucosal layer, but the lymph nodes were negative for malignancy. The other three polyps were diagnosed as TVAs. Because her family history fulfilled the Amsterdam criteria II for hereditary non-polyposis colorectal cancer (HNPCC), genetic analysis was performed. All of the four tumor tissues were classified as microsatellite stable (MSS) according to the National Cancer Institute guideline for analysis of microsatellite instability (MSI). K-ras mutation was detected in both CA and TVA lesions of the carcinoma in adenoma. To clarify relevant alterations of gene expression associated with adenoma-carcinoma progression, the gene expression profiles of these tumor tissues were analyzed by a cDNA array. RESULTS Although the gene expression profiles were similar, insulin-like growth factor-II (IGF-II) was expressed most differentially in CA and TVA tissues. The results were further substantiated by comparison of the gene expression profiles of CA and TVA lesions of the carcinoma in adenoma. CONCLUSION The results suggest that overexpression of IGF-II played an important role in the progression of adenoma to carcinoma in this patient.

Abstract
BACKGROUND Although there are many advantages of a posterior approach to rectal disease, these procedures are not widely accepted because many surgeons fear the postoperative complications. METHODS The medical records were reviewed of 57 patients who underwent a posterior approach to the rectum between January 1980 and December 2002. RESULTS Twenty-eight men and 29 women with a mean age of 70.5 (range 47-83) years underwent either a posterior transsacral (n = 52) or a transsphincteric (n = 5) procedure. Indications for surgery were benign lesions (n = 33), e.g. villous adenoma, rectal prolapse and endometriosis as well as invasive adenocarcinoma (n = 24). All patients with an invasive adenocarcinoma were classified as ASA grade III or IV. Postoperative morbidity occurred in 12 patients (21%), consisting of temporary incontinence, anastomotic leakage, wound infection, and hemorrhage. There was no mortality. During a mean follow-up of 29 (range 2-86) months, 3 patients with a villous adenoma and 2 patients who were treated for a malignant lesion had a locally recurrent lesion. CONCLUSION We believe that a posterior approach to the rectum should be considered for various benign and selected malignant diseases, especially in case of elderly patients or patients with a compromised general condition, and has to be a part of the surgeon's armamentarium.

Abstract
The local excision of a rectal polyp is often wrongly considered to be a minor surgical procedure. In reality, the malignant potential of adenomas and the not-infrequent presence of cancer in larger polyps, require, for their removal, an oncologically correct operation with strict indication and accurate execution. Despite an increasing inclination to extend the indications of endoscopic polypectomies to polyps of larger size and villous configuration, the local surgical approach remains the preferred treatment in most cases. Here the indications and the results of different surgical techniques proposed for the local excision of a rectal polyp are reported. Among these procedures, transanal endoscopic microsurgery is gaining a primary role in many circumstances.

Abstract
BACKGROUND Functional outcome after sphincter-saving operations can be improved by colonic pouch compared to the straight procedure. However, it is not clear whether the colonic pouch has a different behavior in patients treated by low anterior resection with colorectal (LAR) or coloanal anastomosis (CAA). METHODS We evaluated the 1-year results of 75 patients who underwent a sphincter-saving operation for rectal carcinoma or villous tumor of the middle or lower third of the rectum: 18 patients underwent coloanal anastomosis (CAA), in 13 patients we performed a coloanal anastomosis with a colonic pouch (PCAA), 20 patients had low anterior resection (LAR) and 24 had LAR with pouch construction (PLAR). The two groups of patients were similar in terms of age and gender. Anorectal function was assessed 12 months after the initial operation by an interview and anorectal manometry. RESULTS One year after surgery, the daily mean number of defecations was significantly higher in the LAR group than in the other groups (2.0+/-1.5 in CAA group, 2.2+/-1.0 in PCAA, 2.3+/-1.8 in PLAR, 4.1+/-0.7 in LAR; p<0.05). Frequent soiling was observed in all the groups except PLAR. A lower degree of incontinence and a lower frequency of urgency were found in PCAA than in CAA. There were no differences in anal resting pressure and squeeze pressure among the various groups. Greater distensibility and compliance of the neorectum were observed in CAA, PCAA and PLAR compared to LAR, respectively 8.5+/-7.0 ml air/mmHg for CAA, 8.7+/-5.0 ml air/mmHg for PCAA, 6.3+/-4.0 ml air/mmHg for PLAR and 3.1+/-2.7 ml air/mmHg for LAR. A significant inverse linear correlation was present between the mean daily number of defecations and compliance. No difference in sense of incomplete evacuation was observed among the groups of patients. CONCLUSIONS Colonic J-pouch provides an advantage over straight anastomosis in sphincter-saving operations by reducing the daily number of defecations, and the frequencies of fecal soiling and urgency. The role of the pouch seems to be different in LAR compared to CAA. In fact, in LAR the pouch increases compliance and consequently decreases the daily number of defecations. In CAA, the pouch does not reduce the number of defecations or the compliance, but reduces the frequency of fecal soiling and urgency.

Abstract
Large villous adenomas of the rectum are not uncommon and will be encountered often by general and colorectal surgeons in their practices. The approach to large adenomas can be via the colonoscope either transabdominally or transanally. A simple transanal method was instituted by the author in 1992 and has been used up to the time of writing. This involves using a 4-cm diameter transanal operating rectoscope with laparoscopic instruments and the laparoscope itself. The results for 13 patients from January 1992 to April 2001 are reviewed. The method is simple and allows access to lesions up to 15 cm from the anal verge with a low incidence of complications, residual disease, and recurrence.

Abstract
Cystitis glandularis is a benign proliferative disease of the bladder mucosa with a characteristic histopathologic appearance. If a mass lesion is identified, it is resected transurethrally. More extensive surgical management for severe or recurrent cases is poorly characterized in published studies. We present a patient with multiple rapid recurrences of polypoid masses on the trigone causing irritative voiding symptoms. He developed a low-compliance small-capacity bladder and bilateral ureteral obstruction. The patient underwent total cystoprostatectomy with cavernosal nerve sparing and ileal neobladder construction. We advocate such aggressive surgical management in select cases of this disease.

Abstract
INTRODUCTION Transanal resection of rectal villous adenomas or adenocarcinomas can be carried out using various modalities such as operative excision, fulguration, laser coagulation or cryotherapy. Transanal endoscopic microsurgery is currently not widely available. Transanal resection can provide effective palliation for locally advanced rectal tumours in patients unfit for abdomino-perineal excision of rectum. A urological resectoscope can be safely and repeatedly used to resect advanced primary or locally recurrent rectal tumours by colorectal surgeons with urological expertise. This study reports our experience of treating rectal lesions with endoscopic transanal resection (ETAR) using the urological resectoscope. METHODS Patients were identified from one surgeons' prospectively collected operating data. Charts were retrieved and reviewed. RESULTS Over a 13-year period a total of 43 ETAR procedures were carried out in 20 patients (11 males; mean age 74 years; range 54-92 years) using the urological resectoscope. Twelve (60%) patients had a single resection; 8 (40%) patients required more than one resection; the mean number of procedures per patient was 2.2 (range 1-8). The median interval between resections for recurrent disease (excluding planned repeat resections) was 340 days (range 168-2337 days). Histopathology revealed rectal adenoma (with varying degrees of dysplasia) in 11 (55%) patients and adenocarcinoma in 9 (45%). The majority (30; 70%) of resections were carried out in patients with benign disease, with 13 (30%) in patients with rectal adenocarcinoma. Mean operating time per resection was 25 min. Thirteen (30%) resections were carried out under spinal anaesthetic. There was no procedure related mortality. There were no cases of haemorrhage, rectal perforation, 'TUR syndrome' or pelvic sepsis. No patients with benign disease subsequently developed an invasive carcinoma. CONCLUSIONS Accepting that this technique provides limited histopathological information regarding extent of resection and tumour clearance, our experience demonstrates that ETAR of rectal tumours using the urological resectoscope can provide a minimally invasive, effective and safe means of treating and palliating patients with benign and malignant rectal disease. There remains a place for this technique in selected patients.

Abstract
BACKGROUND Patients with inoperable advanced rectal carcinoma require palliation for local symptoms. Endoscopic Nd-Yag laser ablation is a valid palliative treatment option in patients with advanced rectal carcinoma who are poor operative risks due to coexistent multiple comorbidities. METHODS All patients who cannot undergo radical surgery due to various factors such as tumour size, poor risk patients, distant metastasis and refusal to undergo surgery were offered palliation with endoscopic Nd-YAG laser ablation. Indications included troublesome bleeding, local recurrence, mucous discharge and impending obstruction. Patients were admitted on the day of treatment, phosphate enema given for bowel preparation and endoscopic ablation done through a flexible sigmoidoscope under intravenous sedation with midazolam. All patients were discharged the next day after overnight observation. Patients were reviewed every 3 months and laser ablation repeated if deemed necessary. RESULTS Eleven patients (7 males, 4 females; mean age 83.6 years, range 77-90 years) underwent endoscopic laser ablation in a District General Hospital --8 for rectal carcinoma, 2 for rectosigmoid tumour and 1 for recurrent tubulovillous adenoma. The number of treatment episodes varied from 1 to 12 with symptom free interval from 2 to 18 months between treatment episodes. There were 3 failures, one patient required defunctioning colostomy, one patient was referred for radiotherapy due to persistent symptoms and in one patient laser treatment had to be abandoned due to local extent. There were no immediate post-treatment complications, but one patient developed incontinence after 5 episodes which might be attributable to tumour infiltration. DISCUSSION Endoscopic laser ablation is a practical and feasible alternative to other palliative treatment modalities in the management of this unfortunate category of patients due to low morbidity and mortality, short hospitalization and low complication rates.

Abstract
OBJECTIVE The aim of this study was to assess one and a half years experience gained in Lithuania while treating rectal tumors with transanal endoscopic microsurgery in the Centre of Abdominal Surgery of Vilnius University Hospital "Santariskiu klinikos". MATERIALS AND METHODS The patients who had rectal adenomas and low-risk T1 carcinomas of good or moderate differentiation, with no lymphatic and vascular invasion were selected for surgery. Tumor stage was determined by transanal endosonoscopy and rectoscopy with multiple macrobiopsies before surgery. RESULTS A total of 47 patients were operated on. The average tumor size was 3.4+/-1.4 cm (ranged from 1 to 7 cm). Overall 25 (52.1%) carcinomas and 23 (47.9%) adenomas were removed. Pre-operative diagnoses did not correspond to the final clinical diagnoses in 14 (29.8%) cases. Forty-three (89.6%) radical operations (R0) and 5 (10.6%) doubtful complete operations (RX) were performed. One (2.1%) intra-operative complication and one (2.1%) post-operative complication were observed. After the removal of Ca T2 three patients underwent adjuvant radiotherapy. Twenty-six patients were followed up for 3-17 months after operation: 17 after removal of cancer and 9 after removal of adenoma. One (2.1%) recurrence of a tubulovillous adenoma was diagnosed. No other complications were reported. CONCLUSIONS Initial results of transanal endoscopic microsurgery obtained while treating rectal adenomas and low-risk T1 cancers are promising. The low rate of complications and recurrences in this group offers many hopes. The experience of the treatment of T2 cancers with transanal endoscopic microsurgery and adjuvant radiotherapy is limited but the results are encouraging. It is obvious that the results of randomized and controlled trials need to be awaited before definite conclusions can be drawn.

Abstract
Hyperplastic polyps are not thought to carry a malignant potential. They are, therefore, not regularly screened by the majority of clinicians. We present two case reports of serrated adenomas that add to a small but expanding body of clinical and histological evidence that suggests a hyperplastic to neoplastic pathway. Regular colonoscopic surveillance may be indicated in at least some cases of hyperplastic polyposis

Abstract
An 85-year-old woman was admitted to our hospital due to pain and swelling in her right inguinal region. She had a right inguinal hernia. Abdominal computerized tomography revealed an 8 x 8 cm cecal mass and also a 13.5 cm segmental asymmetric nodular thickening of the cecum. Colonoscopic examination revealed a sessile polypoid mucus-secreting mass mimicking carcinoma that narrowed the cecal lumen. Histopathological examinations of sections from colonoscopic biopsy materials on light microscopy revealed villous adenoma morphology. The patient underwent operation, and an 18 x 6 x 4 cm mass, which partially obstructed the cecum, was seen. A right hemicolectomy was performed for complete excision. Histopathological examination revealed a pure villous adenoma, and there was no sign of malignant degeneration. On the 6th postoperative day, the patient was discharged from the hospital. During follow-ups at three-month intervals throughout one year, no abnormal colonoscopic or laboratory findings were assessed. We believe that, in older patients with inguinal hernia, presence of intraabdominal mass should be considered. Furthermore, we showed in this report that villous adenomas can reach significant dimensions without causing any obstructing signs or electrolyte imbalance and can mimic colon carcinoma.
