A79 -year-old woman underwent colonoscopic examination for positive occult blood. Aneoplastic lesion was seen in the orifice of the vermiform appendix. She was referred to our hospital and underwent colonoscopic examination again. The biopsy revealed poorly differentiated adenocarcinoma or mixed adenoneuroendocrine carcinoma(MANEC), and she was diagnosed with carcinoma of the appendix. She was treated by laparoscopic ileocecal resection with lymph node dissection (D3). Histopathological examination revealed goblet cell carcinoid(GCC)of the appendix with serosal invasion...

AIM: To study the transcolonic extraction of the proximally resected colonic specimens by colonoscopic assistance at laparoscopic colonic surgery. METHODS: The diagnoses of our patients were Crohn's disease, carcinoid of appendix and adenocarcinoma of cecum. We preferred laparoscopic total mesocolic resections. Colon and terminal ileum were divided with endoscopic staplers. A colonoscope was placed per anal and moved proximally in the colon till to reach the colonic closed end under the laparoscopic guidance...

Carcinoids (neuroendocrine tumours) are considered the most common primary appendiceal neoplasm. Primary appendiceal tumours are uncommon. Routine histopathological examination of appendicectomy specimens is justified given the not infrequent incidental finding of appendiceal tumours. In cases of appendicitis in the elderly, the index of suspicion for epithelial tumours of the appendix should be raised. Moreover, once the diagnosis of an adenomatous lesion is made, colonoscopic examination of the entire large bowel is mandatory given the frequency of synchronous colorectal neoplasia in our population...

BACKGROUND: Difficulty with the proximal lesion approach and durability of endoscopic ultrasonography (EUS) instruments usually limits its application for lower gaotrointestina (GI) lesions to locoregional staging of rectal cancer. This study investigated the value of colonoscopic miniprobe ultrasonography for differential diagnosis and treatment strategy in patients with colorectal subepithelial lesions (SEL). METHODS: Miniprobe ultrasonography was Performed in 40 consecutive patients with suspected colorectal SEL or residual lesions after endoscopic resection at one medical center by the same endoscopist (C-J Lin)...

Goblet cell carcinoid of the appendix is a rare neoplasm and clinically tends to take a malignant course. Most cases are young and early stage, and the surgical strategy is available. But appropriate chemotherapy for inoperable cases with peritoneal dissemination is not established. A 77-year-old woman with a past history of appendectomy was admitted to our hospital complaining of abdominal fullness. Abdominal computed tomography showed massive ascites and slight contrast enhancement of appendix. A tumor was found by colonoscopic examination at the orifice of vermiform and was diagnosed pathologically as goblet cell carcinoid of the appendix...

The carcinoid tumour of the appendix and the mucocele are entities rather infrequent in children and are normally diagnosed in the course of an appendicectomy that is, in most of the cases, curative. The association of both processes is unusual. The authors present a case of carcinoid tumour of the appendix associated to mucocele in a male, aged 10 patient, who underwent an appendicectomy by suspicion of an acute appendicitis. The histologic study confirmed the presence of a mucocele of the appendix associated to a carcinoid tumour with a 0,7 cm diameter...

BACKGROUND: Since an increasing number of appendectomies are performed via laparoscopy, it is crucial to determine the impact of this approach on appendix carcinoid (AC) outcome. The goal of this study was to compare results of laparoscopic (LAP) versus open (OP) appendectomy for AC according to intend to treat approach. METHODS: A retrospective review (1991-2003) identified 39 patients (median age, 36 years; range, 12-83) treated by laparoscopy (LAP) or laparotomy (OP) for AC in a single institution...

BACKGROUND AND STUDY AIMS: Several factors predict difficult or incomplete colonoscopy with a standard colonoscope, including female gender, low body mass index, extensive diverticulosis, and prior pelvic surgery. PATIENTS AND METHODS: A push-and-pull enteroscopy device and a single-balloon technique was used in 14 patients (six men, eight women; mean age 62 +/- 15 years) after failure of ileocolonoscopy or endoscopic therapy using either a standard or a pediatric colonoscope...

Endocrine tumors (ET) of the digestive tract (formerly called neuroendocrine tumors) are rare. They are classified into two principal types: gastrointestinal ET's (formerly called carcinoid tumors) which are the most common, and pancreaticoduodenal ET's. Functioning ET's secrete polypeptide hormones which cause characteristic hormonal syndromes. The management of ET is multidisciplinary. Poorly-differentiated ET's have a poor prognosis and are treated by chemotherapy. Surgical excision is the only curative treatment of well-differentiated ET's...

Adenocarcinoid of the appendix is an infrequent tumor with histologic features of both adenocarcinoma and carcinoid tumor. Although its malignant potential remains unclear, adenocarcinoids seem to be biologically more aggressive than conventional carcinoids. The aim of this study was to analyze long-term results of surgical treatment for appendiceal adenocarcinoid. A retrospective review (1991-2003) identified seven patients (median age 72, range 27-81 years) treated for appendiceal adenocarcinoid. The clinical data of these patients were reviewed...
