ABSTRACT: OBJECTIVE: Patients with angiodysplastic bleeding in the small intestine have poor therapeutic outcomes. We aimed to evaluate outcomes in patients undergoing balloon-assisted enteroscopy with heat probe or argon plasma coagulation, and to identify risk factors for recurrent bleeding. METHODS: We studied 14 male and 25 female patients aged 12-89 years (64.46 ± 17.28) who were consecutively referred to our institution with angiodysplastic bleeding of the small intestine. These 39 patients underwent balloon-assisted enteroscopy and were followed up over 6 months. RESULTS: Thirty-one patients in our sample had melena and 8 had hematochezia. On balloon-assisted enteroscopy, 26 patients received endoscopic therapy, 3 underwent surgical intervention due to endoscopic therapy failure, and 10 underwent observation because a definite source of bleeding was not identified. Ten patients (25.6%) had recurrent bleeding during follow-up. Eight of these patients had received endoscopic therapy and 2 were under observation. Higher rates of recurrent bleeding were observed in association with presence of melena initially (P = 0.028), but there were no significant differences in the rate of recurrence between patients who did or did not receive endoscopic therapy (P = 0.47). Age greater than 65 years (P = 0.058) and jejunal bleeding (P = 0.05) had the trend towards to increase the risk of recurrent bleeding compared with other factors in the analysis. CONCLUSIONS: Balloon-assisted enteroscopy may be a beneficial approach to treat angiodysplastic bleeding in the small intestine. Elderly patients and those with melena or jejunal bleeding should be closely monitored for recurrent bleeding.

ABSTRACT: BACKGROUND: Gastric subepithelial tumors are usually asymptomatic and observed incidentally during endoscopic examination. Although most of these tumors are considered benign, some have a potential for malignant transformation, particularly those originating from the muscularis propria layer. For this type of tumor, surgical resection is the standard treatment of choice. With recent advent of endoscopic resection techniques and devices, endoscopic submucosal dissection (ESD) has been considered as an alternative way of treatment. The aim of this study is to demonstrate the feasibility of a modified ESD technique with enucleation for removal of gastric subepithelial tumors originating from the muscularis propria layer, and to evaluate its efficacy and safety. METHODS: From November 2009 to May 2011, a total of 16 patients received a modified ESD with enucleation for their subepithelial tumors. All tumors were smaller than 5 cm and originated from the muscularis propria layer of the stomach, as shown by endoscopic ultrasonography (EUS). The procedure was conducted with an insulated-tip knife 2. Patient's demographics, tumor size and pathological diagnosis, procedure time, procedure-related complication, and treatment outcome were reviewed. RESULTS: Fifteen of the sixteen tumors were successful complete resection. The mean tumor size measured by EUS was 26.1 mm (range: 20--42 mm). The mean procedure time was 52 minutes (range: 30--120 minutes). Endoscopic features of the 4 tumors were pedunculated and 12 were sessile. Their immunohistochemical diagnosis was c-kit (+) stromal tumor in 14 patients and leiomyoma in 2 patients. There was no procedure-related perforation or overt bleeding. During a mean follow up duration of 14.8 months (range: 6--22 months), there was no tumor recurrence or metastasis. CONCLUSIONS: Using a modified ESD with enucleation for treatment of gastric subepithelial tumors originating from the muscularis propria layer and larger than 2 cm, complete resection can be successfully performed without serious complication. It is a safe and effective alternative to surgical therapy for these tumors of 2 to 5 cm in size.

ABSTRACT: Abstract Background: Surgery of gastrointestinal stromal tumors (GISTs) has been modified, and laparoscopic resection of GIST has gained improvement and roles. Patients and Methods: We retrospectively reviewed clinical data and oncological outcomes of our GIST patients who underwent laparoscopic surgery and traditional open surgery. In total, 227 pathologically diagnosed GIST cases were retrospectively reviewed in Chang Gung Memorial Hospital at Linkou, Taipei, Taiwan, between 2005 and 2010. We excluded those with tumor size >5 cm, biopsy-only, combined other operation, endoscopic mucosal resection, tumor located in the duodenum, colon-rectum, esophagocardiac junction, omentum, pelvic area, or retroperitoneum, or metastasis when operated on and those diagnosed as other disease after immunohistologic examination of GIST. Fifty-eight cases were enrolled, including 16 patients in the laparoscopic surgery group (LSG) and 42 patients in the open surgery group (OSG). The patients' demography, perioperative, pathologic result, and oncology result were recorded and analyzed. Results: Both groups showed no difference in clinical demography, tumor size, and locations. LSG patients showed fewer days to resume diet, shorter postoperative hospital stays, and less use of patient-controlled analgesia. The postoperative morbidity in LSG and OSG was 6.3% and 19%, respectively. The median follow-up time was 32.73 months in LSG and 39.75 months in OSG. Recurrence or metastasis was observed in 3 patients (1 in LSG and 2 in OSG). The recurrence rate between LSG and OSG showed no significant difference. Conclusions: Laparoscopic surgery was technically feasible for GIST of no more than 5 cm located at the stomach and small bowel. In the current study, we demonstrated that LSG patients benefited from fewer days to resume diet (5 versus 5.71 days), shorter postoperative stays (8 versus 9.07 days), and less patient-controlled analgesia use (6.7% versus 90.9%) during the perioperative period with the same short-term oncology result compared with OSG patients.

ABSTRACT: Opinions regarding the impact of human epidermal growth factor receptor (HER)-2 overexpression or HER-2 amplification on the prognosis of gastric cancer patients are mixed. The present study attempted to clarify this issue by investigating a large cohort of surgical patients.
We investigated 1,036 gastric cancer patients undergoing curative-intent resection. Their surgical specimens were evaluated for HER-2 expression by immunohistochemistry (IHC), and those with HER-2 expression levels of 2+ were additionally subjected to fluorescence in situ hybridization (FISH). Data on demographic and clinicopathological features and relevant prognostic factors in these patients were analyzed.
HER-2 positivity was noted in 64 (6.1%) of 1,036 gastric cancer patients, including 46 patients whose HER-2 expression level was 3+ on IHC and 18 patients whose FISH results were positive. On univariate analysis, HER-2 positivity was more often associated with differentiated histology, intestinal type, and negative resection margins, whereas only differentiated histology was independently associated with HER-2 positivity in a logistic regression model. For stage I-IV gastric cancer, HER-2 was not a prognostic factor. In a subpopulation study, although HER-2 positivity emerged as a favorable prognostic factor for stage III-IV gastric cancer on univariate analysis, it failed to be an independent prognostic factor after multivariate adjustment.
The prevalence of HER-2 positivity, determined using standardized assays and scoring criteria in a large cohort of gastric cancer patients after resection, was 6.1%. HER-2 positivity was phenotypically associated with differentiated histology. HER-2 is not an independent prognostic factor for gastric cancer.

ABSTRACT: Most hepatocellular carcinoma (HCC) is generated from chronic hepatitis and cirrhosis. To discover new markers for early HCC in patients with chronic hepatitis and cirrhosis, we initiated our search in the interstitial fluid of tumor (TIF) via differential gel electrophoresis and antibody arrays and identified secreted ERBB3 isoforms (sERBB3). The performance of serum sERBB3 in diagnosis of HCC was analyzed using receiver operating characteristic curves (ROC). The serum sERBB3 level was significantly higher in HCC than in cirrhosis (p < 0.001) and chronic hepatitis (p < 0.001). The accuracy of serum sERBB3 in detection of HCC was further validated in two independent sets of patients. In discrimination of early HCC from chronic hepatitis or cirrhosis, serum sERBB3 had a better performance than alpha-fetoprotein (AFP) (areas under ROC [AUC]: sERBB3 vs AFP = 93.1 vs 81.0% from chronic hepatitis and 70.9 vs 62.7% from cirrhosis). Combination of sERBB3 and AFP further improved the accuracy in detection of early HCC from chronic hepatitis (AUC = 97.1%) or cirrhosis (AUC = 77.5%). Higher serum sERBB3 levels were associated with portal-vein invasion and extrahepatic metastasis of HCC (p = 0.017). Therefore, sERBB3 are serum markers for early HCC in patients with chronic hepatitis and cirrhosis.

ABSTRACT: Although the outcomes of caustic ingestion differ between children and adults, it is unclear whether such outcomes differ among adults as a function of their age. This retrospective study was performed to ascertain whether the clinical outcomes of caustic ingestion differ significantly between elderly and non-elderly adults.
Medical records of patients hospitalized for caustic ingestion between June 1999 and July 2009 were reviewed retrospectively. Three hundred eighty nine patients between the ages of 17 and 107 years were divided into two groups: non-elderly (< 65 years) and elderly (≥ 65 years). Mucosal damage was graded using esophagogastroduodenoscopy (EGD). Parameters examined in this study included gender, intent of ingestion, substance ingested, systemic and gastrointestinal complications, psychological and systemic comorbidities, severity of mucosal injury, and time to expiration.
The incidence of psychological comorbidities was higher for the non-elderly group. By contrast, the incidence of systemic comorbidities, the grade of severity of mucosal damage, and the incidence of systemic complications were higher for the elderly group. The percentages of ICU admissions and deaths in the ICU were higher and the cumulative survival rate was lower for the elderly group. Elderly subjects, those with systemic complications had the greatest mortality risk due to caustic ingestion.
Caustic ingestion by subjects ≥65 years of age is associated with poorer clinical outcomes as compared to subjects < 65 years of age; elderly subjects with systemic complications have the poorest clinical outcomes. The severity of gastrointestinal tract injury appears to have no impact on the survival of elderly subjects.

ABSTRACT: The technical performance of colonoscopy performed in deeply sedated patients differs from that performed without sedation or under minimal to moderate sedation. The aim of this study is to evaluate the factors affecting cecal intubation during colonoscopy performed under deep sedation.
A total of 5352 consecutive subjects who underwent a screening colonoscopy as part of a health check-up between January 2008 and December 2008 at an academic hospital were reviewed. All endoscopies were performed with deep sedation using combination propofol or propofol alone. Data collected included characteristics of the patients (age, gender, body mass index, bowel habits, history of abdominal or pelvic surgery, quality of bowel preparation, and presence/absence of colonic diverticula) and characteristics of the colonoscopists (experience level, colonoscopy procedure volume, and instrument handling method). These factors were analyzed to evaluate their impact on cecal intubation rates.
The crude cecal intubation rate was 98% and the adjusted cecal intubation rate was 98.3%. The mean cecal intubation time was 5.6 ± 3.2 min. Multivariate logistic regression analysis demonstrated that patient age greater than 60 years, constipation, poor colon preparation and a two-person colonoscopy procedure were independently associated with lower cecal intubation rates.
Colonoscopy performed under deep sedation by experienced colonoscopists results in high cecal intubation rates. Among the significant patient-related predictors influencing the cecal intubation, the quality of the bowel preparation was the only modifiable factor. When performed by experienced hands, the one-person method was associated with higher cecal intubation rates than the two-person method.

ABSTRACT: To assess the long-term outcome of endoscopic hemorrhoid ligation (EHL) for the treatment of symptomatic internal hemorrhoids.
A total of 759 consecutive patients (415 males and 344 females) were enrolled. Clinical presentations were rectal bleeding (593 patients) and mucosal prolapse (166 patients). All patients received EHL at outpatient clinics. Hemorrhoid severity was classified by Goligher's grading. The mean follow-up period was 55.4 mo (range, 45-92 mo).
The number of band ligations averaged 2.35 in the first session for bleeding and 2.69 for prolapsed patients. Bleeding was controlled in 587 (98.0%) patients, while prolapse was reduced in 137 (82.5%) patients. After treatment, 93 patients experienced anal pain and 48 patients had mild bleeding. Patient subjective satisfaction was 93.6%. Repeat treatment or surgery was performed if symptoms were not relieved in the first session. In the bleeding group, the recurrence rate was 3.7% (22 patients) at 1 year, and 6.6% and 13.0% at 2 and 5 years. In the prolapsed group, the recurrence rate was 3.0%, 9.6% and 16.9% at 1, 2 and 5 years, respectively.
EHL is an easy and well-tolerated procedure for the treatment of symptomatic internal hemorrhoids, with good long-term results.

ABSTRACT: To investigate the outcomes, as well as risk factors for 6-wk mortality, in patients with early rebleeding after endoscopic variceal band ligation (EVL) for esophageal variceal hemorrhage (EVH).
Among 817 EVL procedures performed for EVH between January 2007 and December 2008, 128 patients with early rebleeding, defined as rebleeding within 6 wk after EVL, were enrolled for analysis.
The rate of early rebleeding after EVL for acute EVH was 15.6% (128/817). The 5-d, 6-wk, 3-mo, and 6-mo mortality rates were 7.8%, 38.3%, 55.5%, and 58.6%, respectively, in these early rebleeding patients. The use of beta-blockers, occurrence of hypovolemic shock, and higher model for end-stage liver disease (MELD) score at the time of rebleeding were independent predictors for 6-wk mortality. A cut-off value of 21.5 for the MELD score was found with an area under ROC curve of 0.862 (P < 0.001). The sensitivity, specificity, positive predictive value, and negative predictive value were 77.6%, 81%, 71.7%, and 85.3%, respectively. As for the 6-mo survival rate, patients with a MELD score ≥ 21.5 had a significantly lower survival rate than patients with a MELD score < 21.5 (P < 0.001).
This study demonstrated that the MELD score is an easy and powerful predictor for 6-wk mortality and outcomes of patients with early rebleeding after EVL for EVH.

ABSTRACT: Several large studies revealed that selective intestinal decontamination (SID) prevented recurrence of spontaneous bacterial peritonitis (SBP) in cirrhotic patients. Nonetheless, there are no definitive patient selection parameters identifying who would benefit from SID.
To investigate long-term outcomes in cirrhosis patients with recurrence of SBP and to identify predictive factors for SBP recurrence.
We retrospectively studied 146 cirrhosis patients diagnosed with a first episode of SBP from 2005 to 2006. Of these, 89 patients survived; the survivors were divided into two groups based on recurrence and non-recurrence of SBP, and clinical parameters, survival time and cause of death were analysed.
The in-hospital mortality was 39% (57/146). The SBP recurrence rate was 42.7% (38/89). The survival rate between patients with recurrent SBP and those without recurrence did not differ (P=0.092). Sepsis was the major cause of death in the recurrent SBP group, but not in the non-recurrent group. Serum albumin level before discharge and β-blocker use between the two groups differed significantly (P<0.0001). Using the cut-off point for serum albumin level before discharge of 2.85 g/dl as a predictor for recurrence of SBP, the sensitivity was 70.2% and the specificity was 76.3%. Furthermore, long-term survival of the group with high albumin before discharge was better than that of the corresponding group with low albumin (P=0.007).
Spontaneous bacterial peritonitis was associated with high sepsis-related mortality in cirrhotic patients. Serum albumin before discharge was a useful single parameter to predict the recurrence of SBP and long-term survival.

ABSTRACT: A 62-year-old male patient was admitted to our hospital due to severe chest pain, odynophagia, and hematemesis. Chest computed tomography showed an esophageal submucosal tumor. Esophagogastroduodenoscopy (EGD) revealed a longitudinal purplish bulging tumor of the esophagus. Endoscopic ultrasound (EUS) showed a mixed echoic tumor with partial liquefaction from the submucosal layer. The patient was diagnosed with esophageal intramural hematoma as well as achalasia by upper gastrointestinal endoscopy, esophagography and esophageal manometry. The patient was managed conservatively with intravenous nutrition, and oral feeding was discontinued. Follow-up EGD and EUS showed complete recovery of the esophageal wall, and finally, the patient underwent endoscopic dilatation for achalasia. The patient was symptom free at the time when we wrote this manuscript.

ABSTRACT: To analyze the predictive factors for lymph node metastasis (LNM) in early gastric cancer (EGC).
Data from patients surgically treated for gastric cancers between January 1994 and December 2007 were retrospectively collected. Clinicopathological factors were analyzed to identify predictive factors for LNM.
Of the 2936 patients who underwent gastrectomy and lymph node dissection, 556 were diagnosed with EGC and included in this study. Among these, 4.1% of patients had mucosal tumors (T1a) with LNM while 24.3% of patients had submucosal tumors with LNM. Univariate analysis found that female gender, tumors ≥ 2 cm, tumor invasion to the submucosa, vascular and lymphatic involvement were significantly associated with a higher rate of LNM. On multivariate analysis, tumor size, lymphatic involvement, and tumor with submucosal invasion were associated with LNM.
Tumor with submucosal invasion, size ≥ 2 cm, and presence of lymphatic involvement are predictive factors for LNM in EGC.

ABSTRACT: To evaluate the efficacy of endoscopic diagnosis and therapy for jejunal diverticular bleeding.
From January 2004 to September 2009, 154 patients underwent double-balloon enteroscopy (DBE) for obscure gastrointestinal bleeding. Ten consecutive patients with jejunal diverticula (5 males and 5 females) at the age of 68.7 ± 2.1 years (range 19- 95 years) at Chang Gung Memorial Hospital, Academic Tertiary Referral Center, were enrolled in this study.
Of the 10 patients, 5 had melena, 2 had hematochezia, 2 had both melena and hematochezia, 1 had anemia and dizziness. DBE revealed ulcers with stigmata of recent hemorrhage in 6 patients treated by injection of epinephrine diluted at 1:10 000, Dieulafoy-like lesions in 4 patients treated by deploying hemoclips on the vessels, colonic diverticula in 2 patients, and duodenal diverticula in 3 patients, respectively. Of the 2 patients who underwent surgical intervention, 1 had a large diverticulum and was referred by the surgeon for DBE, 1 received endoscopic therapy but failed due to massive bleeding. One patient had a second DBE for recurrent hemorrhage 7 mo later, which was successfully treated with a repeat endoscopy. The mean follow-up time of patients was 14.7 ± 7.8 mo.
DBE is a safe and effective treatment modality for jejunal diverticular bleeding.

ABSTRACT: Signet ring cell carcinoma (SRC) is defined as a histological entity. The clinicopathological characteristics and prognosis of gastric SRC remain controversial.
From 1994 to 2006, 2,439 patients with gastric carcinoma who underwent gastrectomy were enrolled. Of these, 505 patients (20.7%) had SRC and were compared to 1,934 patients with other histological types.
Twenty-nine percent of patients in the SRC group (n = 149) had early gastric cancer, with tumor invasion limited to the mucosa or submucosa, compared to 22.2% of patients in the non-SRC group (n = 430). The proportion of regional LN metastases was 10.7 and 16.0% in early SRC and early non-SRC, respectively, (p = 0.115). The 5-year survival rates for patients with early SRC were better than those for patients with early non-SRC (96.1 vs. 89.6%, p = 0.01).
Early gastric SRC has favorable prognosis. There is no significant difference in terms of LN metastasis between SRC histologic type and other histological types. Less-invasive strategies may be acceptable in selected patients with early gastric SRC.

ABSTRACT: Peutz-Jeghers syndrome (PJS) is a very rare disease that often causes severe complications such as bowel obstruction or gastrointestinal tract bleeding. In the past, it was usually treated by using surgical intervention despite the associated complications. Balloon-assisted enteroscopy (BAE) has been documented as an effective and safe method for the diagnosis and treatment of small bowel lesions. Hence, we conducted this study to verify whether BAE is useful for patients with PJS.
To evaluate the safety and efficacy of BAE with prophylactic polypectomy in patients with PJS.
From August 2005 to February 2010, 6 consecutive patients were diagnosed with PJS after pathological and clinical examination, and underwent BAE examination and polypectomy at Chang Gung Memorial Hospital, an academic tertiary referral center.
Six consecutive patients (4 men and 2 women) diagnosed with PJS underwent BAE with polypectomy. BAE was performed 17 times for complete examination of the entire small bowel. The range of the diameter of the removed polyps was 1-6 cm. No immediate complications such as hemorrhage or hollow organ perforation were noted during the procedure, and no patient developed intussusception during the follow-up period (32 ± 17.5 months).
BAE with polypectomy is useful for patients with PJS in order to reduce the complications of the condition.

ABSTRACT: Immunoparalysis, defined as downregulation of human leukocyte antigen-DR (HLA-DR) expression on monocytes, is strongly associated with septic complications of acute pancreatitis. However, the possible causes of this immunoparalysis have been largely unknown. A prospective case control study was performed in 54 patients with acute pancreatitis and 24 normal volunteers. HLA-DR expression on monocytes and serum cytokine levels were measured. In addition, monocytes from normal volunteers treated with tumor necrosis factor (TNF)-α in vitro were evaluated for HLA-DR expression and cytokine release. HLA-DR expression was significantly lower in patients with severe pancreatitis than in those with mild acute pancreatitis and healthy volunteers (42.28% ± 11.49% vs. 86.85% ± 14.56% vs. 93.92% ± 7.40%, p < 0.0001). Pearson correlation analysis showed that serum TNF-α and serum interleukin-10 levels were both correlated with HLA-DR expression. In addition, exogenous TNF-α could enhance IL-10 secretion from normal monocytes in a dose-response manner. In addition, TNF-α could downregulate the HLA-DR expression on monocytes even in the presence of anti-IL-10 antibodies. Therefore, both TNF-α and IL-10 contributed to the development of immunoparalysis in patients with acute pancreatitis.

ABSTRACT: Double-balloon enteroscopy (DBE) is an effective tool for diagnosing and treating obscure gastrointestinal bleeding. The aim is to describe how outcomes differ with patient setting (with DBE diagnosis and intervention, with DBE diagnosis but without intervention, and without DBE diagnosis), and thus demonstrate the value of endoscopic intervention when encountering potential bleeder during DBE. From November 2003 to January 2008, 90 patients with obscure gastrointestinal bleeding presented with DBE at our tertiary referral center. A total of 113 DBE procedures were carried out. Overall diagnostic yield was 75.6% (68/90). Endoscopic intervention was performed in 58 (85.3%) of the 68 patients with potential bleeder. The 90 patients were divided into three settings: with endoscopic diagnosis and intervention (n = 58), with endoscopic diagnosis but without intervention (n = 10), and without endoscopic diagnosis (n = 22). Rebleeding rates for the three groups were 22.4%, 60%, and 22.7%, respectively. For the 35 patients diagnosed with vascular lesions, the rebleeding rates in patients with and without endoscopic intervention, were 38.5% (10/26) and 66.7% (6/9), respectively. One (0.9%) severe adverse event occurred during the 113 procedures, and the patient died. DBE is an effective tool for diagnosing and treating obscure gastrointestinal bleeding. DBE involves relatively safe procedures and has an acceptable complication rate. When potential bleeders are encountered during the procedure, especially for vascular lesions, therapeutic intervention should be attempted, since the intervention-related complication rate is acceptable, and such intervention can reduce the rebleeding rate and enhance the cost-effectiveness of DBE.

ABSTRACT: This report describes an integrated therapeutic method of double-balloon enteroscopy (DBE) and laparoscopically assisted bowel surgery (LABS) for small bowel diseases.
In this study, 34 patients with obscure gastrointestinal bleeding (OGIB, n=25) and abdominal pain (n=9) who underwent DBE and LABS were analyzed. Demographics, patient characteristics, diagnostic tests, DBE and LABS findings, surgical results, and long-term outcome were reviewed.
All 34 patients underwent DBE without significant complications. Biopsy was performed for 16 patients, ink mark for 25 patients, and temporary homeostasis during DBE for 5 patients. Laparoscopically assisted bowel resection was performed for 27 patients, converted laparotomy for 6 patients, and laparoscopic diagnosis alone for 1 patient. The pathologic diagnoses included gastrointestinal stromal tumor (GIST) for eight patients, primary adenocarcinoma for three patients, lymphoma for three patients, Meckel's diverticulum for three patients, angiodysplasia for three patients, ulcer for two patients, lipoma for four patients, metastasis for three patients, jejunal diverticulosis for two patients, and tuberculosis ileitis, ileal varix, and lymphangioma for one patient each. No surgical mortalities or significant morbidities were noted. After a follow-up period of 14+/-3 months, 29 patients were well without disease recurrence. Two patients had symptomatic recurrence, and three patients died of cancerous progression.
The combination of DBE and LABS represents an ideal therapeutic method, especially for OGIB caused by small bleeding neoplasms or vascular lesions.

ABSTRACT: For many physicians who ordinarily treat patients with colonic diseases, colonoscopy is considered a prime study interest. Developments in colonoscopic equipment and methods have led to larger numbers of endoscopic diagnoses and treatments for colorectal neoplasms. The purpose of this investigation is to evaluate the efficacy and outcomes of endoscopic treatment for colorectal neoplastic lesions and the development of colorectal cancers after colonoscopic therapy.
From September 1999 to May 2005, 19,815 consecutive colonoscopic examinations in 16,318 patients were gathered, totaling 9,534 endoscopic treatments for colorectal neoplasms. Macroscopic characteristics of the neoplasms were classified into protruded (N = 7,455), sessile (N = 1,569), lateral spreading tumor (N = 201), depressed lesions (N = 21), and flat lesions (N = 288). Snare polypectomy was conducted in 7,536 lesions, hot forceps removal in 1,545 lesions, and endoscopic mucosal resection in 353 lesions.
Histological diagnoses were 8,333 neoplastic lesions (8,246 adenomas with low/high-grade dysplasia and 87 invasive adenocarcinomas) and 1,201 non-neoplastic lesions (1,186 hyperplastic and 15 inflammatory polyps). For the adenocarcinoma group, all had received further operations, while 73 surgical specimens discovered no residual tumors. Four perforations and 146 bleedings were found following endoscopic treatment. No procedure-related mortality was found and no recurrent malignancy was found after 6-71 months follow-up.
To lower the incidence and mortality of advanced colorectal cancer, endoscopic treatment for colorectal neoplasms is a simple and safe procedure.
