Can we predict an incomplete capsule endoscopy? Results of a multivariate analysis using a logistic regression model

Background and aims: small bowel capsule endoscopy (SBCE) does not reach the cecum within the battery lifetime in approximately 15-35 % of patients. Incomplete examinations result in diagnostic delays and increase the economic burden. To date, risk factors for incomplete examinations have been described with contradictory results. The aims of this study were to analyze the rate and identify risk factors for incomplete examinations, excluding capsule retentions, in a large cohort of patients.Methods: data from 1,894 consecutive SBCE examinations performed from January 2009 to December 2015 were analyzed. Variables recorded included demographics, past medical and surgical history, biochemical parameters and procedure characteristics. The rate of incomplete examinations, excluding capsule retentions, was calculated and a multivariate analysis using a logistic regression model was performed in order to evaluate predictive factors.Results: the incidence of incomplete examinations, excluding capsule retentions, was 10.1 % (187 incomplete procedures). The multivariate analysis showed that age > 65 years, gastric transit time > 41 minutes and SB transit time > 286 minutes are predictive factors for incomplete examinations, increasing the probability of this event by 199 % (OR: 1.99; 95 % CI: 1.34-2.95), 260 % (OR: 2.60; 95 % CI: 1.72-3.93) and 352 % (OR: 3.52; 95 % CI: 2.26-5.48), respectively.Conclusions: age > 65 years, gastric transit time > 41 minutes and SB transit time > 286 minutes are predictive factors for incomplete examinations excluding capsule retentions. Both age and gastric transit time events are known before the procedure ends. Therefore, pharmacologic or endoscopic measures may be taken into account to avoid incomplete examinations. (AU)

Factors that predict the presence of non-small bowel lesions during capsule endoscopy examinations.

We read the papers by Juanmartiñena et al. entitled "Colonic lesions in patients undergoing small bowel capsule endoscopy: incidence, diagnostic and therapeutic impact" and "Gastroduodenal lesions detected during small bowel capsule endoscopy: incidence, diagnostic and therapeutic impact".

Therapeutic impact of colon capsule endoscopy with PillCam(TM) COLON 2 after incomplete standard colonoscopy: a Spanish multicenter study

Introduction: Colon capsule endoscopy (CCE) is an alternative approach for the examination of the colon in patients who refuse colonoscopy or after incomplete colonoscopy (IC). We conducted a study to determine the frequency of complete colonoscopy after IC, the diagnostic yield of CCE, the therapeutic impact of lesions found in CCE, the level of colon cleanliness and the safety of the procedure. Methods: We performed a prospective, multicenter study involving ten Spanish hospitals. Consecutive outpatients aged ≥ 18 years with previous IC were invited to participate. The latest version of the CCE device, PillCam(TM) COLON 2 (CCE-2), was administered to all patients according to the protocol. Results: The study population comprised 96 patients. The most frequent cause of IC was the inability to move past a loop using standard maneuvers (75/96 patients, 78%). Complete visualization of the colon was obtained with CCE-2 in 69 patients (71.9%). Of the 27 patients in whom the CCE-2 did not reach the hemorrhoidal plexus, it passed the colonic segment explored with the previous colonoscopy in 20 cases; therefore, it could be inferred that a combined approach (CCE-2 plus colonoscopy) enabled complete visualization of the colonic mucosa in 92.7% of patients. CCE-2 revealed new lesions in 58 patients (60.4%). Polyps were the most frequent finding (41 patients; 42.7% of the total number of patients). In 43 of the 58 patients (44.8% of the total number of patients), the new lesions observed led to modification of therapy, which included a new colonoscopy for polyp resection or surgery in patients with colonic neoplasm. Conclusions: CCE-2 is a suitable diagnostic procedure that can lead to more frequent diagnosis of significant colonic lesions after IC (AU)

Signet ring cell carcinoma of the jejunum: an uncommon finding within the reach of capsule endoscopy.

An 80 year-old female presented with ductal breast carcinoma (stage II) three years ago, complained of asthenia and iron-deficiency anemia. No diagnosis was obtained after conventional endoscopy and iron supplements were indicated. Ten months later visible digestive hemorrhage was presented. Upper and lower endoscopy was repeated but non-diagnosis was obtained. Thus, video capsule endoscopy was indicated identifying a stenotic lesion arising in the mucosa of distal jejunum. Histopathological examination revealed a poorly mucinous differentiated signet-ring cell adenocarcinoma with an intense peri-tumoral lymphoid (Crohn´s-like lymphoid reaction) and lympho-vascular infiltration with no nodal metastases (pT3N0;7ª edition TNM classification). Immunochemistry revealed negative stained for estrogen and progesterone receptors in contrast with prior breast cancer. Thus, metastatic origin was rule out. Primary small-bowel malignancies are extremely rare. They account for 2% of all gastrointestinal tract malignancies. Carcinoid tumor (40%), adenocarcinoma (33%), lymphoma (17%) and sarcoma (8%) are most common histological types. Symptomatic lesions are rare, but when present: gastrointestinal bleeding, abdominal pain and weight loss are most common digestive symptoms. Primary signet ring cell adenocarcinoma is a rarely histopathological variety of adenocarcinoma with poor prognosis, usually identified in esophageal or gastric locations (95%). They are less commonly detected in remaining gastrointestinal tract, and when present, metastatic origin must always rule out. Nowadays, diagnostic delayed is common and leads to detected small bowel neoplasms at late stages with poor treatment outcomes. Thus, capsule endoscopy may help to improve this situation as it may identify them at early stages.

Mixed adenoneuroendocrine carcinoma (MANEC) of the gastroesophageal junction: a case report and review of the literature

Esophageal cancer is the fourth most common neoplasm of the gastrointestinal tract. It is responsible for 1.7% of all deaths related with cancer. The two main types of esophageal cancer are squamous cell carcinoma and adenocarcinoma. Other types of esophageal cancer are uncommon. We present a 57-year-old man admitted to the hospital with nausea and vomiting due to a high-grade malignant mixed adenoneuroendocrine carcinoma of the gastroesophageal junction. The patient underwent Ivor-Lewis esophagectomy and adyuvant chemoradiotherapy. At 8-month follow-up he was alive without evidence of recurrence (AU)
