ABSTRACT

OBJECTIVE: To establish the incidence and risk factors for progression to high-grade intraepithelial neoplasia (HG-IEN) or Barrett's esophageal adenocarcinoma (BAc) in a prospective cohort of patients with esophageal intestinal metaplasia [(BE)]. BACKGROUND: BE is associated with an increased risk of BAc unless cases are detected early by surveillance. No consistent data are available on the prevalence of BE-related cancer, the ideal surveillance schedule, or the risk factors for cancer. METHODS: In 2003, a regional registry of BE patients was created in north-east Italy, establishing the related diagnostic criteria (endoscopic landmarks, biopsy protocol, histological classification) and timing of follow-up (tailored to histology) and recording patient outcomes. Thirteen centers were involved and audited yearly. The probability of progression to HG-IEN/BAc was calculated using the Kaplan-Meier method; the Cox regression model was used to calculate the risk of progression. RESULTS: HG-IEN (10 cases) and EAc (7 cases) detected at the index endoscopy or in the first year of follow-up were considered to be cases of preexisting disease and excluded; 841 patients with at least 2 endoscopies {median, 3 [interquartile range (IQR): 2-4); median follow-up = 44.6 [IQR: 24.7-60.5] months; total 3083 patient-years} formed the study group [male/female = 646/195; median age, 60 (IQR: 51-68) years]. Twenty-two patients progressed to HG-IEN or BAc (incidence: 0.72 per 100 patient-years) after a median of 40.2 (26.9-50.4) months. At multivariate analysis, endoscopic abnormalities, that is, ulceration or nodularity (P = 0.0002; relative risk [RR] = 7.6; 95% confidence interval, 2.63-21.9), LG-IEN (P = 0.02, RR = 3.7; 95% confidence interval, 1.22-11.43), and BE length (P = 0.01; RR = 1.16; 95% confidence interval, 1.03-1.30) were associated with BE progression. Among the LG-IEN patients, the incidence of HG-IEN/EAc was 3.17 patient-years, that is, 6 times higher than in BE patients without LG-IEN. CONCLUSIONS: These results suggest that in the absence of intraepithelial neoplastic changes, BE carries a low risk of progression to HG-IEN/BAc, and strict surveillance (or ablative therapy) is advisable in cases with endoscopic abnormalities, LG-IEN or long BE segments.

ABSTRACT

This study is aimed to assess the long-term health-related quality of life (HRQL) of patients after esophagectomy for esophageal cancer in comparison with established norms, and to evaluate changes in HRQL during the different stages of follow-up after esophageal resection. A systematic review was performed by searching medical databases (Medline, Embase and the Cochrane Library) for potentially relevant studies that appeared between January 1975 and March 2011. Studies were included if they addressed the question of HRQL after esophageal resection for esophageal cancer. Two researchers independently performed the study selection, data extraction and analysis processes. Twenty-one observational studies were included with a total of 1282 (12-355) patients. Five studies were performed with short form-36 (SF-36) and 16 with European Organization for Research and Treatment of Cancer (EORTC) QLQ C30 (14 of them also utilized the disease-specific OES18 or its previous version OES24). The analysis of long-term generic HRQL with SF-36 showed pooled scores for physical, role and social function after esophagectomy similar to United States norms, but lower pooled scores for physical function, vitality and general health perception. The analysis of HRQL conducted using the Global EORTC C30 global scale during a 6-mo follow-up showed that global scale and physical function were better at the baseline. The symptom scales indicated worsened fatigue, dyspnea and diarrhea 6 mo after esophagectomy. In contrast, however, emotional function had significantly improved after 6 mo. In conclusion, short- and long-term HRQL is deeply affected after esophagectomy for cancer. The impairment of physical function may be a long-term consequence of esophagectomy involving either the respiratory system or the alimentary tract. The short- and long-term improvement in the emotional function of patients who have undergone successful operations may be attributed to the impression that they have survived a near-death experience.

ABSTRACT

Incidence of esophageal cancer (EC) is rising more rapidly in the Western world than that of any other cancer. Despite advances in therapy, more than 50% of patients have incurable disease at the time of presentation. This precludes curative treatment and makes palliative treatment a more realistic option for most of these patients. Dysphagia is the predominant symptom in more than 70% of patients with EC and although several management options have been developed in recent years to palliate this symptom, the optimum management is not established. Self-expanding metal stents (SEMS) are a well-established palliation modality for dysphagia in such patients. Health-related quality of life (HRQoL) is becoming a major issue in the evaluation of any therapeutic or palliative intervention. To date, only a few published studies can be found on Medline examining HRQoL in patients with advanced EC treated with SEMS implantation. The aim of this study was to review the impact on HRQoL of SEMS implantation as palliative treatment in patients with EC. All Medline articles regarding HRQoL in patients with advanced EC, particularly those related to SEMS, were reviewed. In most studies, relief of dysphagia was the only aspect of HRQoL being measured and SEMS implantation was compared with other palliative treatments such as brachytherapy and laser therapy. SEMS insertion provides a swift palliation of dysphagia compared to brachytherapy and no evidence was found to suggest that stent implantation is different to laser treatment in terms of improving dysphagia, recurrent dysphagia and better HRQoL, although SEMS insertion has a better technical success rate and also reduces the number of repeat interventions.

ABSTRACT

Endoscopic endoluminal radiofrequency ablation (RFA) is a novel and promising modality for Barrett's esophagus (BE) treatment. Actually the only surveillance method after the ablation treatment is random biopsies throughout the whole treated area. Confocal laser endomicroscopy (CLE) is a new endoscopic imaging tool that permits high-resolution microscopic examination of the gastrointestinal tract. The technology has garnered increasing attention because of its ability to provide real-time "optical" biopsy specimens, with a very high sensitivity and specificity. This paper summarize the potential application of CLE in the surveillance of the reepithelialization of BE, after endoscopic RFA.

ABSTRACT

CONTEXT: Cystic dystrophy in heterotopic pancreas is a rare and serious condition. Diagnosis is difficult because of non-specific clinical manifestations and radiologic and endoscopic imaging are pivotal. Therapeutic management is still under debate. CASE REPORT: We describe a case of cystic dystrophy of the duodenal wall in heterotopic pancreas complicated with chronic pancreatitis and pancreatic cystadenoma. DISCUSSION: Computed tomography and magnetic resonance are very useful in demonstrating the presence of cysts in a thickened duodenal wall but, for the most part, endoscopic ultrasonography is the most useful imaging examination. The choice of different therapeutic options is still under debate; although some authors have proposed a medical approach using octreotide or endoscopic treatment for selected patients, a pancreaticoduodenectomy is usually proposed for symptomatic patients. CONCLUSION: When surgery is needed, a pancreaticoduodenectomy is preferred, reserving by-pass procedures for high risk patients. Because of the non-specific clinical manifestation and the very difficult diagnosis and therapeutic management, these patients should be studied and treated in specialized and dedicated centers.

ABSTRACT

On the basis of a review of the literature and description of a clinical case, the aim of this paper was to evaluate the role of pancreaticoduodenectomy as the primary therapeutic choice in a rare, serious condition such as cystic dystrophy of the duodenal wall in heterotopic pancreas. The diagnosis is difficult because of the non-specific clinical manifestations, and radiological and endoscopic imaging are decisive. Computed tomography and magnetic resonance are very useful for demonstrating the presence of cysts in a thickened duodenal wall but endoscopic ultrasonography is the most useful imaging examination. The choice of therapeutic option is still debated. Although some Authors have proposed a medical approach using octreotide or endoscopic treatment for selected patients, pancreaticoduodenectomy is usually proposed for symptomatic patients. When surgery is needed, pancreaticoduodenectomy should be preferred, reserving by-pass procedures for high-risk patients. Because of the non-specific clinical manifestations and the very difficult diagnostic and therapeutic management, these patients need to be studied and treated in specialised, dedicated centres.

ABSTRACT

Hydatid disease of the liver is a relatively frequent disease. Although the natural history is almost completely known, several complications may occur. The aim of this study was to show that radical surgical resection of the hepatic hydatid cyst is a safe and very effective technique, based on our results after 30-year experience. A review of most significant studies was carried out. We retrospectively evaluated our surgical cases. From January 1973 to December 2003 we treated 216 patients, 98 males and 118 females. Survival was compared with the Kaplan-Meier test, using log-rank analysis to compare data. Differences with a p value less than 0.05 were considered significant. A total of 279 cysts were excised. We performed pericystectomy in 122 cases, 73 of which closed. We also performed 19 atypical resections, 10 segmentectomies, 20 lobectomies and 2 percutaneous treatments. In more than 90% of cases, preoperative data collection was completed by preoperative ultrasound. The cumulative morbidity was 13%. The recurrence rate amounted to 4.3% at 5 years and 7% at 10 years: of these, 6 occurred after non-radical surgery and 2 after total pericystectomy or liver resection (p < 0.001). Technical advances and accumulated experience permit safe treatment of hepatic hydatid cysts by radical resection, with an almost zero recurrence rate, making it the treatment of choice over partial resection. The utility of percutaneous treatment remains confined to limited indications, such as laparoscopy.

ABSTRACT

BACKGROUND: Placement and removal of the intragastric balloon for obesity are performed endoscopically often under general anesthesia. We propose a safer and faster technique for endoscopic removal of the intragastric balloon using standard sedation. METHODS: In 87 obese patients, we performed 3 removal techniques: 1) standard gastroscope and foreign body forceps, 2) standard gastroscope and retrieval snare, 3) double-channel gastroscope and foreign body forceps plus symmetrical "shark model" polypectomy snare. Balloon retrieval time, number of times the grasping devices lost the balloon, amount of antispasmodic drug, symptoms cumulative score and VAS score for discomfort were evaluated. RESULTS: The technique by double-channel gastroscope and foreign body forceps plus symmetrical polypectomy shark retrieval snare showed a significantly lower balloon retrieval time, number of lost balloons, total number of ampoules used, symptoms cumulative score and VAS score compared to the other two techniques (Dunn's P<0.05). Number of lost balloons was positively associated with number of antispasmodic ampoules used, balloon retrieval time and VAS score. CONCLUSIONS: Technique by double-channel gastroscope and foreign body forceps plus symmetrical polypectomy shark retrieval snare, allows balloon removal safely, quickly and easily, avoiding loss of the balloon, with good patient endurance.
