A case of coffee-ground emesis in an elderly patient

KEY CLINICAL MESSAGE: Black esophagus is an exceeding rare disorder with a multifactorial etiology. Clinical presentation is generally related to upper gastrointestinal bleeding. Diagnosis is based on endoscopic images. Overall mortality is largely related to the underlying medical condition

Metastatic tumors to the stomach: clinical and endoscopic features.

AIM: To evaluate the clinical and endoscopic patterns in a large series of patients with metastatic tumors in the stomach. METHODS: A total of 64 patients with gastric metastases from solid malignant tumors were retrospectively examined between 1990 and 2005. The clinicopathological findings were reviewed along with tumor characteristics such as endoscopic pattern, location, size and origin of the primary sites. RESULTS: Common indications for endoscopy were anemia, bleeding and epigastric pain. Metastases presented as solitary (62.5%) or multiple (37.5%) tumors were mainly located in the middle or upper third of stomach. The main primary metastatic tumors were from breast and lung cancer and malignant melanoma. CONCLUSION: As the prognosis of cancer patients has been improving gradually, gastrointestinal (GI) metastases will be encountered more often. Endoscopic examinations should be conducted carefully in patients with malignancies, and endoscopic biopsies and information on the patient's clinical history are useful for correct diagnosis of gastric metastases

Polypoid vascular malformation of the small intestine.

A 56-year-old man underwent capsule endoscopy because of obscure GI bleeding. Capsule endoscopy showed a pink and somewhat nodular polypoid lesion of the small bowel partially obstructing the intestinal lumen (A). The patient underwent an ileal resection and the operative specimen showed loss of mucosal folds and the presence of an erythematous area with a polypoid formation of 3.5 × 3 cm (B). Histologic examination revealed the presence of numerous ectatic thin-walled blood vessels and a small number of thick-walled vessels in the submucosa (C and D, arrows; H&E, orig. mag. ×4), surrounded by hypertrophic muscularis mucosae and a chronic inflammatory infiltrate that infiltrated the muscularis propria; the diagnosis of polypoid angiodysplasia was suggested. There has been no recurrence of GI bleeding 14 months after the ileal resection

Laparoscopic Cholecystectomy with a Mixed Approach in a Patient with Kartagener Syndrome: Technical Report and Review of Literature

Kartagener syndrome (KS) is a rare autosomal recessive disease. The disease is characterized by three typical symptoms: chronic sinusitis, situs viscerum inversus (SVI), and bronchiectasis. The laparoscopic cholecystectomy (LC) is the standard procedure in most cases of cholelithiasis, but in SVI patients it can be difficult, especially for right-handed surgeons. We report the case of a 24-year-old female affected by KS, presenting with a history of symptomatic cholelithiasis. Ultrasound and magnetic resonance cholangiopancreatography confirmed SVI totalis and cholelithiasis. The patient underwent a laparoscopic cholecystectomy by a right-handed surgeon performed with a mixed approach without complications. Laparoscopic cholecystectomy in SVI patients can be a safe and reliable technique especially for a left-handed surgeon. The described technique is also easy for a right-handed surgeon. However, it is considered a technically challenging procedure and often requires technical modification

Segmental transverse colectomy. Minimally invasive versus open approach: results from a multicenter collaborative study

The role of minimally invasive surgery in the treatment of transverse colon cancer is still controversial. The aim of this study is to investigate the advantages of a totally laparoscopic technique comparing open versus laparoscopic/robotic approach. Three hundred and eighty-eight patients with transverse colon cancer, treated with a segmental colon resection, were retrospectively analyzed. Demographic data, tumor stage, operative time, intraoperative complications, number of harvested lymph nodes and recovery outcomes were recorded. Recurrences and death were also evaluated during the follow-up. No differences were found between conventional and minimally invasive surgery, both for oncological long-term outcomes (recurrence rate p = 0.28; mortality p = 0.62) and postoperative complications (overall rate p = 0.43; anemia p = 0.78; nausea p = 0.68; infections p = 0.91; bleeding p = 0.62; anastomotic leak p = 0.55; ileus p = 0.75). Nevertheless, recovery outcomes showed statistically significant differences in favor of minimally invasive surgery in terms of time to first flatus (p = 0.001), tolerance to solid diet (p = 0.017), time to first mobilization (p = 0.001) and hospital stay (p = 0.004). Compared with laparoscopic approach, robotic surgery showed significantly better results for time to first flatus (p = 0.001), to first mobilization (p = 0.005) and tolerance to solid diet (p = 0.001). Finally, anastomosis evaluation confirmed the superiority of intracorporeal approach which showed significantly better results for time to first flatus (p = 0.001), to first mobilization (p = 0.003) and tolerance to solid diet (p = 0.001); moreover, we recorded a statistical difference in favor of intracorporeal approach for infection rate (p = 0.04), bleeding (p = 0.001) and anastomotic leak (p = 0.03). Minimally invasive approach is safe and effective as the conventional open surgery, with comparable oncological results but not negligible advantages in terms of recovery outcomes. Moreover, we demonstrated that robotic approach may be considered a valid option and an intracorporeal anastomosis should always be preferred

Can Computed Tomography Colonography Replace Optical Colonoscopy in Detecting Colorectal Lesions?: State of the Art

: Colorectal cancer is an important cause of morbidity and mortality worldwide. Optical colonoscopy (OC) is widely accepted as the reference standard for the screening of colorectal polyps and cancers, and computed tomography colonography (CTC) is a valid alternative to OC. The purpose of this review was to assess the diagnostic accuracy of OC and CTC for colorectal lesions. A literature search was performed in PubMed, Embase, and Cochrane Library, and 18 articles were included. CTC has emerged in recent years as a potential screening examination with high accuracy for the detection of colorectal lesions. However, the clinical application of CTC as a screening technique is limited because it is highly dependent on the size of the lesions and has poor performance in detecting individual lesions <5 mm or flat lesions, which, although rarely, can have a malignant potential

Detection of colonic dysplasia in patients with ulcerative colitis using a targeted fluorescent peptide and confocal laser endomicroscopy: A pilot study

Targeted molecular probes have been used to detect sporadic colonic dysplasia during confocal laser endomicroscopy (CLE) with promising results. This is a feasibility pilot study aiming to assess the potential role of CLE combined with a fluorescent-labeled peptide to stain and detect dysplasia associated with Ulcerative Colitis

SPECIFIC DYSPEPTIC SYMPTOMS ARE ASSOCIATED WITH POOR RESPONSE TO THERAPY IN PATIENTS WITH GASTROESOPHAGEAL REFLUX DISEASE

Background: In gastroesophageal reflux disease (GORD) patients, coexistence of functional dyspepsia (FD) is known to be associated with poor response to proton pump inhibitors (PPIs), but the contribution of specific dyspepsia symptoms has not been systematically investigated yet. Objective: To characterize the impact of dyspepsia symptoms on PPIs response in GORD patients. Methods:. The enrolled subjects were 100 patients with diagnosis of GORD. All patients underwent a 24 hour pH-impedance test, while on PPIs-therapy. Patients were divided into two groups, refractory and responders, according to the persistence of GORD symptoms. A standardized questionnaire for FD was also administered to assess presence of dyspepsia symptoms. Results: In the subgroup of refractory patients FD was more prevalent than in responder ones, with postprandial fullness, nausea, vomiting, early satiation and epigastric pain being significantly prevalent in refractory GORD-patients. In the multivariate analysis only early satiation and vomiting were significantly associated with poor response to PPIs Conclusion: Coexistence of FD is associated with refractory-GORD. We showed that only early satiation and vomiting are risk factors for poor response to PPIs therapy. Our findings suggest that symptoms of early satiation and vomiting would help to identify the subset of PPIs-refractory GORD patients
