Comparison of DaVinci Si and Xi robotic platforms for adrenal surgery. Effects on short term outcomes.

OBJECTIVES: To evaluate our experience and short term surgical outcomes between two robotic systems. METHODS: The present study retrospectively analyzed 38 cases, who underwent robotic adrenalectomy between 2012-2019 at our center. The patients were divided into Group Si (n=11) and Group Xi (n=27), and the results of these two groups were compared. RESULTS: Demographic characteristics of both groups were similar between two groups. While, 42% of the patients had Cushing syndrome, 22% had Pheochromocytoma and 22% had Conn syndrome in the Xi group, 72% of the patients were non-secreting adrenocortical adenoma in Si group (p=0.005). The mean docking time in Group Xi was shorter than Si group (p=0.027). Console and total operation times were similar in both groups (p=0.312 and p=0.424; respectively). The intraoperative complication rate (p=0.500) and hospital stay (3.2±1.0 vs. 2.52±1.42 days, respectively, p = 0.077) were similar in both groups. Postoperative 4th and 12th hour Visual Analog Scale (VAS) scores were similar (p=0.213 and p=0.857; respectively). The average cost of robotic consumables was $210 higher in Xi group (p=0.495). CONCLUSION: Our study shows that; the Xi robotic system is as safe as the Si system for adrenalectomy operations. KEY WORDS: Adrenal gland surgery, Minimally invasive adrenalectomy, Robotic surgery.

Is Helicobacter pylori eradication required after laparoscopic sleeve gastrectomy?

Introduction: Helicobacter pylori is the most common bacterial infection in humans. H. pylori is now known to be responsible for chronic gastritis, peptic ulcer, B-cell gastric lymphoma, and gastric adenocarcinoma. Laparoscopic sleeve gastrectomy (LSG) is increasingly preferred among surgical treatment methods in obese patients. Aim: To discuss the detection and treatment of H. pylori in patients undergoing LSG surgery. Material and methods: Patients who underwent biopsy with upper gastrointestinal endoscopy in the preoperative and postoperative period of LSG between 2014 and 2019 were included in the study, resulting in a sample of 162 patients who underwent preoperative and postoperative endoscopy. Endoscopic biopsies of these patients were collected in accordance with the preoperative Sydney protocol. The patients did not receive H. pylori-related eradication treatment. Endoscopy was performed to investigate dyspeptic complaints in the postoperative period. The biopsy results obtained in the endoscopy in the postoperative period were compared to those obtained in the preoperative period. Results: Of the 162 patients in our study, 39 were male and 123 were female. All patients were assigned to one of two groups in the preoperative period: H. pylori (+) and H. pylori (-). H. pylori was found to be positive in 99 patients in the preoperative period. H. pylori was negative in 62 patients in the biopsy results of these patients after the LSG. H. pylori was found to be negative in 63 patients in the preoperative period, and 51 patients were H. pylori-negative in the biopsy results of these patients following LSG. These changes were found to be statistically significant when the preoperative and postoperative pathology results were evaluated (p < 0.01). Conclusions: This study showed that LSG reduced the presence of H. pylori.

What is the Treatment Role of Transpapillary Cholecystostomy for Delayed Cholecystectomy in the Coexistence of Acute Cholecystitis and Cholangitis.

INTRODUCTION: This study aims to investigate the role of main bile duct drainage and gallbladder transpapillary drainage in the treatment of patients who diagnosed with acute cholecystitis and acute cholangitis because of choledocholithiasis. MATERIALS AND METHODS: Patients who were admitted to the hospital with the diagnosis of acute cholecystitis between January 2018 and December 2019, have hyperbilirubinemia in their laboratory tests, and who were diagnosed with choledochal stone by magnetic resonance imaging and magnetic resonance cholangiopancreatography imaging because of the findings of cholangitis were included in this study. These patients underwent endoscopic retrograde cholangiopancreatography (ERCP) and choledochus stone extraction procedure and gallbladder drainage with the transpapillary pigtail. The demographic data, success rates, and complications of the patients were evaluated. RESULTS: A total of 19 patients were included in the study. Choledochus was cannulated in all patients, but gallbladder drainage could not be achieved in 2 patients. These 2 patients were recorded under the unsuccessful method use. Although 2 patients could not be operated because of high comorbidity (American Society of Anesthesiologists IV), they underwent percutaneous cholecystostomy because of the development of cholecystitis arising from an obstruction in the pigtail catheter in the 11th and 12th weeks. Treatments of the remaining 15 patients and subsequent cholecystectomy procedures were successful. The mean age of the patients was 54.52 years. Of the patients, 9 were female and 6 were male. In the 6th week of follow-up, 15 patients underwent laparoscopic cholecystectomy with ERCP 1 day after removal of the stent and pigtail catheter. CONCLUSIONS: Transpapillary cholecystectomy with ERCP is a successful method of treatment in patients with acute cholecystitis with the symptoms of cholangitis because of choledochal stone.

Small bowel prolapse from anus: Atypical presentation of rectal perforation.

Non-traumatic rectum perforation is rarely seen if there is no underlying tumor formation. The perforations in the middle and lower parts of the rectum that are under the peritoneal reflex are asymptomatic unless there is intraabdominal infection or inflammation. In this study, we aim to present a patient who referred to the emergency surgery clinic with the small bowel prolapse from the anus.

Feasibility of Thyroid Imaging Reporting and Data System Classification in Predicting Thyroid Malignancy.

In this study, we aimed to evaluate the diagnostic value of thyroid imaging reporting and data system (TIRADS) in the estimation of malignancy and assess the concordance between TIRADS and the histopathology results of the postoperative specimens. Consecutive ultrasound imaging records of patients with multinodular goiter from January 2010 to December 2017 who underwent surgery were retrospectively reviewed. The risk of malignancy of each TIRADS category was determined, and correlation with pathology was assessed. The patients with malignant cytology findings (Bethesda 6) who were categorized TIRADS 6 were excluded from the study. The positive and negative predictive values, sensitivity, specificity, and accuracy of the TIRADS classification were calculated on a 2 × 2 table with their own formulas. A total of 1457 patients were evaluated, and 1122 of these were included in the study. The risk of malignancy for nodules evaluated as TIRADS 2 was 0.6 per cent, TIRADS 3 was 13.1 per cent, TIRADS 4a was 20 per cent, TIRADS 4b was 61.1 per cent, TIRADS 4c was 85.7 per cent, and TIRADS 5 was 93.3 per cent. The positive predictive value of TIRADS classification was found to be 43.4 per cent, negative predictive value was found to be 90.7 per cent, sensitivity was found to be 78 per cent, specificity was found to be 68.4 per cent, and accuracy was found to be 70.7 per cent for our institution. The TIRADS classification based on suspicious ultrasound findings is reliable in predicting thyroid malignancy and can be routinely used in daily practice.
