NCT ID: NCT05983003 Completed - Surgery Clinical Trials

Research on Identifying and Treatment Prognosis of Chronic Rhinosinusitis Based on Image and Sequencing Data

Start date: March 2015
Phase:
Study type: Observational

This project focuses on researching chronic rhinosinusitis in patients, employing image processing techniques and molecular biology methods to jointly determine the research objectives: 1. Investigating heterogeneity. 2. Developing an intelligent assessment model. 3. Creating a visual tool for diagnosis and prognosis.

NCT ID: NCT05923151 Completed - Clinical trials for Postoperative Complications

The Cranial-caudal Mixed Medial Approach for Laparoscopic Right Hemicolectomy

Start date: February 1, 2017
Phase: N/A
Study type: Interventional

To explore the feasibility and effectiveness of the cranial-caudal mixed medial approach in laparoscopic right hemicolectomy with complete mesocolic excision. Laparoscopic right hemicolectomy using the cranial-caudal mixed medial approach is safe and feasible, can shorten the operation time, reduce the risk of intraoperative bleeding, and has good clinical results.

NCT ID: NCT05391269 Completed - Appendicitis Clinical Trials

Review of the Pathological Results of Appendectomy Specimens

Start date: January 1, 2021
Phase:
Study type: Observational

This is a retrospective review study to evaluate the histopathological findings post appendectomy

NCT ID: NCT04708119 Completed - Pathology Clinical Trials

Histopathologic Changes in Dental Follicle Associated With Radiographically Normal Impacted Lower Third Molars

Start date: April 1, 2019
Phase: N/A
Study type: Interventional

This study aimed to evaluate the incidence of histopathologic changes in dental follicles associated with radiographically normal impacted lower third molar and to determine the relationship between cystic changes in follicle tissues and age, gender, and the angular position of the impacted tooth.

NCT ID: NCT04675281 Completed - Covid19 Clinical Trials

Pathological Findings of Fatal COVID-19

HISTOCOVID
Start date: April 22, 2020
Phase:
Study type: Observational

The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a new coronavirus discovered in December 2019 in Wuhan, China and currently responsible of a worldwide outbreak and the death of more than 55,000 patients in France. The more severe form of COVID-19 disease induces a pneumonia with profound hypoxemia which may require invasive mechanical ventilation. It is estimated that 5% of COVID-19 patients are admitted to the Intensive Care Unit (ICU) for management. Hospital mortality in patients who develop severe acute respiratory distress syndrome (ARDS) ranges between 40% and 60%. The investigators purpose to investigate the pathological findings of COVID-19 patients who died from ARDS in the ICU by doing post-mortem lung biopsies

NCT ID: NCT04383249 Completed - Pathology Clinical Trials

Routine Pathological Examination of Hernia Sac; Is it a Workload or Necessary?

Start date: January 1, 2020
Phase:
Study type: Observational

Routine microscopic examination of the hernia sac is controversial. While some centers do not recommend a routine microscopic examination in inguinal hernias in adult patients, they recommend them in abdominal wall hernias. The investigators aimed to discuss the pathology results and unexpected histopathological findings who underwent abdominal wall and inguinal hernia operation in the light of the literature.

NCT ID: NCT04363125 Completed - Pathology Clinical Trials

Review of Isolated Hypoganglionosis and Presentation of a New Case Complicated With Sigmoid Volvulus

Start date: January 1, 2019
Phase:
Study type: Observational

Isolated hypoganglionosis is rare and constitutes 3-5% of all congenital neurological bowel diseases. Since hypoganglionosis is associated with symptoms such as chronic constipation or pseudo-obstruction, it can be confused with Hirschprung's disease and it is important to make a differential diagnosis before treatment. Our aim in this study; In addition to sharing the rarely isolated hypoganglionosis and sigmoid volvulus in a 45-year-old male patient with mental retardation, the investigators present a systematic comprehensive review of hypoganglionosis.

NCT ID: NCT04360525 Completed - Pathology Clinical Trials

Different Clinicopathological Features of Non-Elderly Sigmoid Volvulus Patients

Start date: January 1, 2020
Phase:
Study type: Observational

Sigmoid volvulus is frequently seen in male patients over 60 years old. In the sigmoid volvulus <60 age groups, the male/female ratio is close to each other. If sigmoid volvulus develops in <60 age groups, it is more likely to be another underlying organic pathology.

NCT ID: NCT04356768 Completed - Pathology Clinical Trials

Histological Analysis of Sacrococcygeal Pilonidal Sinus Specimens

Start date: March 1, 2020
Phase:
Study type: Observational

Minimally invasive techniques have been widely used routinely and reliably in the treatment of pilonidal sinus. In some of these methods, the cavity of sinus remains in the patient; this condition caused us to question the necessity of pathological examination. Except for prolonged duration of disease, elderly age, macroscopic suspicion, and recurrence; We think that routine pathological examination of the pilonidal sinus is unnecessary.

NCT ID: NCT04352478 Completed - Pathology Clinical Trials

Incidental Cancer in Gallbladder Surgical Specimens Focus on Elderly Patients

Start date: January 20, 2020
Phase:
Study type: Observational

Causes such as long-term stones and polyp are thought to play a role in the etiology of gallbladder cancer. The routine histopathological examination provides the detection of incidental gallbladder cancers. It should be remembered that acute or chronic cholecystitis accompanied by the thicked wall and a prolonged history of gallstones may be the cause of malignancy, especially in elderly patients.
