RESUMO
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. METHODS: In this single-center, prospective, observational study, 915 patients who underwent colonoscopy between July 2023 and April 2024 were evaluated. Failure to achieve cecal intubation due to poor bowel preparation and a history of colorectal surgery were considered as exclusion criteria. Patients with a CIT ≥ 11 min or those with technically failed cecal intubation were categorized into the prolonged CIT subgroup, while those with a CIT < 11 min were analyzed in the normal CIT subgroup. Patients were evaluated based on demographic characteristics, clinical parameters, and colonoscopy results. RESULTS: A total of 902 patients included in the final analysis. The median age was 55 years and 55.4% of them were women. The cecal intubation rate was 97.5% (892 patients). The polyp, adenoma, and malignancy detection rate were 27.4, 20.7, and 1.9%, respectively. Median cecal intubation time (CIT) was 6 min (Interquartile range: 4-8). In multivariate analysis, body mass index ≤ 18.5, previous abdominal surgery, increased Wexner Constipation Score, and lesser endoscopist experience were associated with prolonged CIT. CONCLUSIONS: BMI, previous abdominal surgery, severity of constipation, and the experience of endoscopist may affect CIT. Considering these factors during daily planning in the endoscopy unit can lead to more efficient facility utilization.
RESUMO
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. Pre- and postoperative dysphagia scoring was calculated and used to evaluate postprocedure improvement in quality of life. Procedural success and early and late complication rates were investigated. RESULTS: A total of 171 endoscopic procedures were performed in 73 patients. Procedural success was 95.8% (n = 69) and dilatation was performed in 80 patients. The rate of perioperative complication was 26% (n = 19). After 1 month, stents were patent in all patients (n = 73). Stent obstruction was noted in 6 patients: 2 each at 2, 7, and 10 months. CONCLUSION: SEMS usage for palliative and curative purposes in benign or malignant upper gastrointestinal system obstructions is an efficient and reliable treatment method with advantages, such as shortening hospital stay, decreased pain, cost-effectiveness, and low mortality-morbidity rates when compared to surgical procedures, and a high rate of clinical success.

INTRODUCTION: Endoscopic retrograde cholangiopancreatography (ERCP) with sphincterotomy is the first step treatment modality of choledocholithiasis. In spite of an extended sphincterotomy, 10-15% of complex choledochal stones (larger than 15 mm and/or more than 3 stones) cannot be removed and recurrent ERCP procedures may be needed. AIM: To evaluate the role and efficiency of multiple biliary stent application in the treatment of large and multiple choledochal stones. MATERIAL AND METHODS: Patients with complex choledochal stones and patients with inadequate choledochal clearance during ERCP were included in the study. The study group was divided into 2 groups as the placement of single (n = 27 patients) or multiple stents (n = 58 patients). After a mean time interval of 21 days (10-28), the ERCP procedure was tried for the second time and a stent was placed in case of recurrence. RESULTS: Successful biliary drainage was provided in both groups. The decrease in the longitudinal or transverse size of the stones after stent placement was found to be statistically significant in both groups (p = 0.001). Cholestatic enzymes (alkaline phosphatase (ALP), γ-glutamyltransferase (GGT)) and bilirubin levels decreased significantly in both groups following stenting (p = 0.001). Additionally, multiple stents functioned as a bridge starting from the first ERCP to full clearance in patients with large and multiple stones which could not be removed at once and saved them from the possible morbidities of an invasive operation. CONCLUSIONS: Endoscopic multiple biliary stent placement should be preferred in the treatment of patients with complex choledochal stones and high rates of co-morbidity, as a safe alternative to surgery.
RESUMO
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. MATERIAL AND METHODS: This was a prospective, randomized, double-blind study of propofol versus midazolam and meperidine in 100 patients scheduled for diagnostic upper gastrointestinal endoscopy. The patients were divided into propofol and midazolam/meperidine groups. Randomization was generated by a computer. Cardiopulmonary side effects (hypotension, bradycardia, hypoxemia), procedure-related times (endoscopy time, awake time, time to hospital discharge), and patient and endoscopist satisfaction were compared between groups. RESULTS: There was no significant difference between the groups with respect to the cost, endoscopy time, or demographic and clinical characteristics of the patients. Awake time and time to hospital discharge were significantly shorter in the propofol group (6.58 ±4.72 vs. 9.32 ±4.26 min, p = 0.030 and 27.60 ±7.88 vs. 32.00 ±10.54 min, p = 0.019). Hypotension incidence was significantly higher in the propofol group (12% vs. 0%, p = 0.027). The patient and endoscopist satisfaction was better with propofol. CONCLUSIONS: Propofol may be preferred to midazolam/meperidine sedation, with a shorter awake and hospital discharge time and better patient and endoscopist satisfaction. However, hypotension risk should be considered with propofol, and careful evaluation is needed, particularly in cardiopulmonary disorders.
RESUMO
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. MATERIAL AND METHODS: Patients with acute malignant colonic obstruction who underwent endoscopic stenting between 2011-2014 were retrospectively reviewed. Data included demographic features, localization of obstruction, endoscopic stenting indications, rate of technical and clinical success, complications, morbidity and mortality. RESULTS: Endoscopic stent was successfully placed in 77 out of 82 procedures (93.9%). A colostomy was placed in five cases in which endoscopic stent could not be inserted. There were complications in seven patients with technically successful stents (9.0%). These included three stent migrations, one perforation, and rectal hemorrhage in three patients. There were no stent-related deaths. CONCLUSION: The mortality rate of emergency surgery for malignant bowel obstruction is relatively high. The use of colonic stents can avoid surgery in patients who are not suitable for emergency surgery and may allow adequate time for preoperative preparation, counseling and staging for those who are suitable for further intervention. We believe that self-expandable metallic stent placement is a safe, effective, and minimal invasive alternative treatment method for malignant colonic obstruction.
RESUMO
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. The purpose of this report is to present a case that reached immense dimensions in the perianal region, and to emphasize the importance of wide surgical excision. A 17-year-old woman presented with a giant mass in the perianal region for 2 years, which progressively increased in size. Local examination revealed a large vegetative lesion in the perianal area. Wide surgical excision of the involved skin and lesion was undertaken. The wound was reconstructed by bilateral gluteal fasciocutaneous V-Y advancement flap. Response to various treatments is often poor, with a high recurrence rate. In conclusion, surgical treatment with wide excision and plastic reconstruction is an effective therapy for giant anal condylomas.
RESUMO
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. METHODS: A total of 148 men with a unilateral hernia were randomized prospectively to undergo TEP or Lichtenstein repair. In both groups, unilateral resistive indices, pulsatile indices of capsular and intratesticular artery flow, and testicular volume (in milliliters) were measured preoperatively and 6 months postoperatively by the use of grayscale and color Doppler ultrasonography (CDUS). The primary outcomes of the study were postoperative findings from history, physical examination, and CDUS measurements at 6 months postoperatively. Demographics, clinical and operative data, CDUS measurements, and recurrence patterns were analyzed. RESULTS: Of 148 procedures, 134 cases consisting of 64 TEP and 70 Lichtenstein repairs were evaluated. Pre- and postoperative CDUS findings, rates of complications, and recurrence in both groups did not show any difference. Operative time was greater with a Lichtenstein repair (36 vs 30 minutes; P = .01). CONCLUSION: Complications and recurrence rates and effects on testicular perfusion and testicular volume in both laparoscopic and open techniques are similar, whereas the laparoscopic approach has shorter operative time than open hernia repair.
