Active clinical trials for "Diverticulum"

Rationale: Older African Americans undergoing surgery are a vulnerable and growing population at high risk for poor surgical outcomes and disparities. Few programs have focused on this population due to a fragmented understanding of the needs of this population. Objectives: While socioecological determinants of health (SEDOH) such as health literacy and socioeconomic status are known drivers of surgical disparities, an estimated 36-47% of surgical disparities remains unexplained. This gap results from limitations of current clinical datasets in capturing SEDOHs. This pilot study aims to fill this gap by (i) collecting granular SEDOH data, (ii) identifying barriers to surgical care for older African Americans, and (iii) establishing a multi-institutional clinical database through a socioecological context. These findings will help understand how SEDOHs drive surgical disparities and inform development of interventions to eliminate them in elderly African Americans. Design and Methods: Guided by the socioecological model of health, the investigators will use mixed-methods to achieve the objectives. First, the investigators will assess the acceptability and feasibility of a 58-item SEDOH survey based on the NIH PhenX toolkit. After distributing this survey to 36 elderly (≥65 years) African American patients undergoing surgery at 3 rural, UAB-affiliated hospitals (Alex-City, Greenville, Demopolis) the investigators will conduct detailed theory guided assessments of acceptability and feasibility (SA1). Second, the investigators will conduct key informant interviews of individuals from all 5 socioecological levels at each rural hospital (n=10) to identify additional barriers and facilitators to surgical care. The investigators will purposively sample 100% of participants at the patient and caregiver level (n=12) to be elderly African Americans (SA2). Finally, the investigators will link measured SEDOH data with standardized clinical data at each hospital to establish a novel database (SA3). These findings will establish a process to measure SEDOHs across the Deep South and set the foundation for a unique database to study surgical disparities. Significance: Development of effective multilevel interventions to eliminate surgical disparities in older African Americans is dependent on a clearer understanding of the contextual drivers of these disparities. This pilot study will accelerate understanding of these mechanism(s) through SEDOHs. It will establish a process to measure SEDOHs, identify additional barriers to surgical care not captured by NIH instruments, and build the database to study these relationships. Such findings will have the potential to impact vulnerable surgical populations in the Deep South and support the Deep South RCMAR mission to promote health and optimize health outcomes for older and rural African Americans.

This study is to evaluate the performance of Hemospray for the teatment of nonvariceal lower gastrointestinal bleeding.

Patients were recruited over a four year period from 1996 to 1999. Those admitted in the years 1996 and 1997 were retrospectively accrued from the clinical records, while patients treated between 1998 and 1999 patients were entered on the database prospectively on admission. Inclusion criteria All consecutive patients with left sided acute diverticulitis diagnosed clinically by the presence of abdominal pain, associated with leukocytosis (>11x109) and/or fever >38°C, confirmed by imaging (CT scan, ultrasonography, water soluble contrast enema) either alone or in combination and/or by operative findings, entered the study. The CT criteria for the diagnosis included a localized thickening (≥4 mm) of the colonic wall and signs of inflammation of the pericolic fat, with abscess and/or extraluminal air and/or extraluminal contrast. The criteria for ultrasound included at least two of the following signs: bowel wall thickening (>4 mm), diverticular inflammation, pericolic fat edema, intramural or pericolic inflammatory mass, intramural fistula. The diagnostic criteria for water soluble contrast enema included segmental luminal narrowing and a tethered mucosa with or without a mass effect or extravasation of contrast and/or the presence of extraluminal air. Exclusion criteria Patients with inflammatory bowel disease, irritable bowel syndrome, colorectal cancer or diseases precluding adequate follow up, were excluded from the study. Treatment Patients were treated conservatively (antibiotics, I.V. nutrition, CT/US guided abscess drainage) or surgically according to the local policy of each center. Follow up Follow up was carried out according to local policy. The following data were collected: persistence or recurrence of chronic symptoms attributable to complicated diverticular disease, new episodes of AD, new hospital admissions for AD, type of treatment and outcome. Recurrence was defined as a new episode of AD requiring hospitalization that occurred at least 2 months after complete resolution of the index episode which resulted in inclusion in the study. If surgery was performed, the timing, type of procedure, Hinchey stage and complications were recorded. Data collection A standardized flow sheet was used to collect data on medical history, diagnostic work up, type of treatment and follow up to create a dedicated database. Gender, age, date of hospital admission and discharge, diagnosis on admission and discharge, co-morbidities (diabetes mellitus, cardiovascular disease, atherosclerosis, liver or renal failure), symptoms experienced before admission and their duration, history of diverticulosis, previous episodes of AD, laboratory tests, and treatment performed were recorded. Where surgery was performed, the date and type of procedure, the operative findings including Hinchey's classification (16) and details of the operation (incision, extension of resection, type of anastomosis, covering stoma, drains), pathology report, and postoperative complications occurring within 30 days, were all recorded. End points The primary endpoint was to assess the rate of recurrence of AD requiring hospitalization during the follow-up period. Additional endpoints were to assess the risks of emergency surgery, stoma and disease-related mortality during the follow up.

Transvaginal hybrid procedures are of interest as an available NOTES-Procedure for the clinical routine. Few authors have demonstrated the feasibility and safety of such procedures (e.g. cholecystectomy) in selected patient collectives. In 2008 Lacy at al. published the experience with a transvaginal sigmoidectomy as a first in human report. The aim of this prospective data collection is to evaluate the feasibility and safety of the transvaginal hybrid anterior resection in the clinical routine. Therefore all patients giving the informed consent to the transvaginal hybrid anterior resection will be included and assessed concerning feasibility to perform the transvaginal approach and complete the operation transvaginally.

This is a prospective randomized study of 114 patients. The purpose of this study is to compare the efficacy of two standard methods of analgesia for pain control in patients undergoing elective colon and rectal surgery, as measured by the Numeric Pain Scale (NPS) and by the need for supplemental narcotic analgesics. This study is designed to determine if postoperative pain control by local analgesics delivered through preperitoneally placed ON-Q Silver SoakerTM catheters (CPA) is equivalent to continuous epidural analgesia (CEA).

The General Objective of this study is to investigate the cost and efficacy of treating patients undergoing colorectal surgical resections with an opioid limited pain control regimen as part of an Enhanced Recovery After Surgery (ERAS) Protocol. This group will be compared to a traditional opioid based pain control regimen.

Background & Aims: Abnormal colonic pressure profiles have been associated with an increased risk of colonic diverticulosis. A surgical history is a known risk factor for abdominal adhesions, and these may lead to increased intraluminal colonic pressure. We assessed whether previous abdominal surgery is associated with colonic diverticulosis or diverticulitis. Methods: The investigators analyzed data from a prospective study of patients undergoing colonoscopy for different indications from 2020 through 2021. Patients completed a structured questionnaire concerning previous abdominal surgeries, dietary and lifestyle exposures including smoking and alcohol use, and co-morbidities.

To study the influence of different types of periampullary diverticulum(PAD) on ERCP difficult cannulation and postoperative complications.

Mental disorders have been shown to be associated with a number of general medical conditions (also referred to as somatic or physical conditions). The investigators aim to undertake a comprehensive study of comorbidity among those with treated mental disorders, by using high-quality Danish registers to provide age- and sex-specific pairwise estimates between the ten groups of mental disorders and nine groups of general medical conditions. The investigators will examine the association between all 90 possible pairs of prior mental disorders and later GMC categories using the Danish national registers. Depending on whether individuals are diagnosed with a specific mental disorder, the investigators will estimate the risk of receiving a later diagnosis within a specific GMC category, between the start of follow-up (January 1, 2000) or at the earliest age at which a person might develop the mental disorder, whichever comes later. Follow-up will be terminated at onset of the GMC, death, emigration from Denmark, or December 31, 2016, whichever came first. Additionally for dyslipidemia, follow-up will be ended if a diagnosis of ischemic heart disease was received. A "wash-out" period will be employed in the five years before follow-up started (1995-1999), to identify and exclude prevalent cases from the analysis. Individuals with the GMC of interest before the observation period will be considered prevalent cases and excluded from the analyses (i.e. prevalent cases were "washed-out"). When estimating the risk of a specific GMC, the investigators will consider all individuals to be exposed or unexposed to the each mental disorder depending on whether a diagnosis is received before the end of follow-up. Persons will be considered unexposed to a mental disorder until the date of the first diagnosis, and exposed thereafter.

The goal of this observational study is to study the emergency surgical treatment of diverticular disease in Sweden outside clinical trials. The main questions it aims to answer are: Which is the preferred surgical method of acute diverticular disease in Sweden? Which are the short and long-term outcomes of the different surgical methods? Researchers will compare the different methods to see if there is a surgical operation that is superior for the treatment of acute diverticulitis.
