Factors predict prolonged colonoscopy before the procedure: prospective registry study.

Background: Colonoscopy difficulty and procedure time can vary between cases, posing challenges for daily scheduling in endoscopy units. In the literature, cecal intubation time (CIT) is commonly used to assess colonoscopy difficulty, yet there is debate regarding the factors influencing CIT. This prospective observational study aimed to evaluate the factors influencing CIT.

Management of Nonocclusive Mesenteric Ischemia in Patients with Cardiac Failure.

Aim: This study aimed to evaluate the surgical procedures, outcomes, and prognostic factors in patients with ischemic heart disease who were operated on due to nonocclusive mesenteric ischemia (NOMI).

Material And Methods: This research contains all patients diagnosed with congestive heart failure and NOMI between January 2011 to January 2020. The patients who had angiography or CT that showed occlusion of more than 50% in any of the main branches of the mesenteric artery or patients who presented with symptoms in correlation with a total occlusion were excluded from the study.

Usefulness of Endoscopic Tattooing Before Neoadjuvant Therapy in Patients with Clinical Complete Response in Locally Advanced Rectal Cancer for Providing a Safe Distal Surgical Margin.

Endoscopic tattooing of colorectal tumors enables tumor localization and determination of appropriate surgical margins. It becomes very difficult to detect the distal surgical margins (DSMs) of rectal tumors in patients who obtain clinical complete response (cCR) after neoadjuvant therapy. In this study, our aim is to examine the benefits of endoscopic tattooing of the tumor before neoadjuvant therapy in patients with locally advanced rectal cancer in accurate localization of the previous tumor and in providing appropriate DSMs in cases with cCR.

Emergency computed tomography for the diagnosis of acute appendicitis: How effectively we use it?

Background: Technological developments support using ultrasonography (US) in all patients, if available, and advanced diagnostic methods such as abdominal computed tomography (CT) in case of clinical suspicion during diagnostic process of acute appendicitis. We aimed to investigate whether CT was appropriately and efficiently used in the diagnosis of acute appendicitis.

Methods: Between May 2013 and February 2016, 811 patients who underwent appendectomy were retrospectively reviewed from an IRB-approved database, and those who underwent a preoperative CT were enrolled into the study.

Clinical Outcomes of Upper Gastrointestinal Stents and Review of Current Literature.

Background And Objectives: The self-expandable metal stent (SEMS) is an alternative for several possible surgical and palliative treatments of upper gastrointestinal obstructions that occur in several disease states. The present study was performed to describe a single-center experience with upper gastrointestinal stents.

Methods: All patients at a single center who had an SEMS placed for the treatment of obstruction over a 3-year period were retrospectively evaluated.

Ostomy in Nontraumatic Conditions: Our Experience and Review of the Literature.

A number of nontraumatic acute abdomen can result in peritonitis leading to sepsis. In emergent conditions, various procedures like segmentary colectomy and/or subtotal colectomy with anastomosis, Hartmann's procedure, transverse colectomy, and/or expandable metallic stent (SEMS) placement can be performed, considering the status of the patient and the facilitaties of the institution. In our study, we examined the cases diagnosed as acute abdomen without the history of trauma, which had lead to a procedure requiring colostomy.

A comparison of propofol and midazolam/meperidine sedation in upper gastrointestinal endoscopy.

Introduction: There is increasing interest in sedation for upper gastrointestinal endoscopy (UGE). Prospective randomized studies comparing sedation properties and complications of propofol and midazolam/meperidine in upper gastrointestinal endoscopy (UGE) are few.

Aim: To compare propofol and midazolam/meperidine sedation for UGE in terms of cardiopulmonary side effects, patient and endoscopist satisfaction and procedure-related times.

Delaying surgery after neoadjuvant chemoradiotherapy improves prognosis of rectal cancer.

Aim: To investigate the prognostic effect of a delayed interval between neoadjuvant chemoradiotherapy (CRT) and surgery in locally advanced rectal cancer.

Methods: We evaluated 87 patients with locally advanced mid- or distal rectal cancer undergoing total mesorectal excision following an interval period after neoadjuvant CRT at Şişli Hamidiye Etfal Training and Research Hospital, Istanbul between January 2009 and January 2014. Patients were divided into two groups according to the interval before surgery: < 8 wk (group I) and ≥ 8 wk (group II).

Giant perianal condyloma acuminatum: Reconstruction with bilateral gluteal fasciocutaneous V-Y advancement flap.

Condyloma acuminatum caused by human papilloma virus is the most common sexually transmitted infection in the anogenital region. On the other hand, giant condyloma acuminatum that is also known as Buschke-Lowenstein tumor is a rare disease. Its primary treatment is surgical excision.

Endoscopic stent placement in the management of malignant colonic obstruction: Experiences from two centers.

Objective: Intestinal obstruction due to colorectal tumors requires immediate surgical decompression. Endoscopic stent placement for acute malignant colonic obstruction is gaining widespread acceptance as an alternative to emergency surgery. Our aim in this study was to evaluate the success and complication rates of endoscopic stenting for malignant colonic obstruction.

Single Incision Laparoscopic Cholecystectomy for Gallbladder Duplication.

Duplication of the gallbladder is a rare congenital anomaly of the gallbladder, with an estimated prevalence of 1-3 per 3800 individuals. Unless properly diagnosed preoperatively, it can lead to biliary tract injuries and postoperative complications which may require reoperative surgeries. While previously reported cases have been treated with conventional laparoscopic cholecystectomy (LC), treatment with single incision laparoscopic surgery (SILS) has not been reported yet.

Prediction of the grade of acute cholecystitis by plasma level of C-reactive protein.

Background: Acute cholecystitis is the most common complication of gallbladder stones. Today, Tokyo guidelines criteria are recommended for diagnosis, grading, and management of acute cholecystitis.

Objectives: We aimed to evaluate the levels of C-reactive protein (CRP) at different cut-off values to predict the severity of the disease and its possible role in grading the disease with regard to the guideline.

Effects of totally extraperitoneal (TEP) and Lichtenstein hernia repair on testicular blood flow and volume.

Background: Laparoscopic totally extraperitoneal hernia repair (TEP) has been compared with the open technique in several studies in terms of technical properties and perioperative outcomes. There are few studies that compare the long-term effects of each technique on testicular structure and function on the side of the hernia repair. The objective of this study is to investigate the effects at 6 months of the TEP and the Lichtenstein technique on testicular volume and arterial flow by the use of Doppler ultrasonography.

Minimal invasive management of anastomosis leakage after colon resection.

The gold standard of surgical treatment of colorectal anastomotic leak is abdominal drainage of collected fluid and stoma formation. Conventional laparotomy has been the preferred approach for treatment. However, both laparoscopic surgical techniquesand endoscopic stenting have gained popularity over the past years as minimal invasive approaches, especially in the management and treatment of perforations of the gastrointestinal system.

Cardiopulmonary safety of propofol versus midazolam/meperidine sedation for colonoscopy: a prospective, randomized, double-blinded study.

Background: Different levels of pharmacological sedation ranging from minimal to general anesthesia are often used to increase patient tolerance for a successful colonoscopy. However, sedation increases the risk of respiratory depression and cardiovascular complications during colonoscopy.

Objectives: We aimed to compare the propofol and midazolam/meperidine sedation methods for colonoscopy procedures with respect to cardiopulmonary safety, procedure-related times, and patient satisfaction.
