RESUMEN
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.
RESUMEN
BACKGROUND: Antioxidants have been considered a rational curative strategy to prevent and cure liver diseases involving oxidative stress. An acute obstructive jaundice rat model was established to investigate the in vivo hepatoprotective efficacy of Rosa pimpinellifolia L. METHODS: The experimental jaundice model was performed by binding the main bile duct in 25 male Sprague-Dawley rats. All rats were randomly divided into five groups: first group: laparotomy-sham-only, second group: biliary tract binding (control), and third, fourth, and fifth groups: treatment groups with 250, 500, and 750 mg/kg fruit extracts daily, respectively. RESULTS: Considering dosage, although there was no significant therapeutic effect in the 250 mg/kg of Rosa pimpinellifolia L. group, the best results were found in the 500 mg/kg dose group, while results in the 750 mg/kg dose group showed consistent correlation with proinflammatory response. With regard to biochemical parameters, lipid hydroperoxide level in the rat serum and liver tissue was significantly decreased in all treatment groups. Amadori products, which are one of the early markers of glycol-oxidative stress, showed statistical significance in the treatment. CONCLUSION: It was revealed that the antioxidant effect of Rosa pimpinellifolia L. was more prominent in the early stages of hepatic injury secondary to oxidative stress.

RESUMEN
Aim: The aim of this study was to investigate the effect of the largest metastatic lymph node (MLN) size on postoperative outcomes of patients with stage II-III gastric cancer (GC). Methods: A total of 163 patients with stage II/III GC who underwent curative surgery were included in this single-center retrospective study. The lymph nodes were counted, each lymph node was analyzed for metastatic involvement by histopathological examination, and the diameter of the largest metastatic lymph node was recorded. The severity of postoperative complications was assessed by Clavien-Dindo classification system. Two groups of 163 patients were defined according to ROC analysis with cut-off value of histopathologically maximum MLN diameter. A comparative analysis of demographic and clinicopathological characteristics of the patients and their postoperative outcomes were performed. Results: The median hospital stay was significantly longer in patients with major complications compared to patients without major complications [18 days (IQR: 13-24) vs. 8 days (IQR: 7-11); (p < 0.001)]. The median MLN size was significantly larger in deceased patients compared to survived [1.3â cm (IQR: 0.8-1.6) vs. 0.9â cm (IQR: 0.6-1.2), respectively; (p < 0.001)]. The cut-off value of MLN size predicting mortality was found as 1.05â cm. MLN size ≥1.05â cm had nearly 3.5 times more negative impact on survival. Conclusions: The largest metastatic lymph node size had a significant association with survival outcomes. Particularly, MLN size over 1.05â cm was associated with worse survival outcomes. However, the largest MLN was not shown to have any effect on major complications. Further prospective and large-scale studies are required to draw more precise conclusions.
RESUMEN
INTRODUCTION: The increasing incidence of Stenotrophomonas maltophilia ( S. maltophilia ) infections raises concern because of the high fatality/case ratio. This study aimed to evaluate the risk factors for infection and mortality associated with S. maltophilia bloodstream infections (BSIs) in children and compare them with Pseudomonas aeruginosa BSIs. METHODS: All BSIs caused by S. maltophilia (n:73) and P. aeruginosa (n:80) were enrolled in this study between January 2014 and December 2021 at the Medical School of Ege University. RESULTS: Previous Pediatric Intensive Care Unit (PICU) admission, prior glycopeptide, and carbapenem use were significantly more common in patients with S. maltophilia BSIs ( P = 0.044, P = 0.009, and P = 0.001, respectively) than with P. aeruginosa BSIs. C-reactive protein (CRP) levels were significantly higher in S. maltophilia BSIs ( P = 0.002). Multivariate analysis showed that prior carbapenem use was associated with S. maltophilia BSIs ( P = 0.014, adjusted odds ratio [AOR]: 2.710; 95% confidence interval [CI]: 1.225-5.992). PICU admission because of BSI, prior carbapenem and glycopeptide use, neutropenia, and thrombocytopenia were significantly more common in patients with mortality because of S. maltophilia BSIs ( P < 0.001, P = 0.010, P = 0.007, P = 0.008, P = 0.004, respectively), while only PICU admission because of BSI, and prior glycopeptide use were significant in multivariate analysis (AOR, 19.155; 95% CI: 2.337-157.018; P = 0.006 and AOR, 9.629; 95% CI: 1.053-88.013; P = 0.045, respectively). CONCLUSION: Prior carbapenem use is a significant risk factor for developing S. maltophilia BSIs. PICU admission because of BSI and prior glycopeptide use are risk factors associated with the mortality rate in patients with S. maltophilia BSIs. Therefore, S. maltophilia should be considered in patients with these risk factors, and empirical treatment should include antibiotics for S. maltophilia .

BACKGROUND: Candidemia is a life-threatening infection in hospitalied children. This study aimed to evaluate candidemia's demographic and clinical characteristics and identify the risk factors and outcomes of Candida albicans (CA) and non-albicans Candida (NAC) spp. METHODS: A retrospective cohort was designed to evaluate paediatric patients with candidemia between January 2008 and December 2020. RESULTS: A total of 342 episodes in 311 patients were evaluated. The median age of the patients was 2.1 years (1 month-17 years and 6 months), and 59.6% were male. The prevalence of NAC (67.5%) candidemia was higher than that of CA (32.5%). The most commonly isolated Candida species was Candida parapsilosis (43.3%), followed by C. albicans (32.5%), Candida glabrata (6.1%) and Candida tropicalis (5.0%). The length of hospital stay prior to the positive culture and the total length of hospital stay were longer in the NAC group (p = .003 and p = .006). The neutrophil count was lower in the NAC group (p = .007). In the multivariate analysis, total parenteral nutrition, antifungal prophylaxis and a history of coagulase-negative staphylococci (CoNS) culture positivity in the past month were risk factors for developing candidemia due to NAC (p values were .003, .003 and .045). C. albicans and C. parapsilosis fluconazole resistance were 9.5% and 46.6%, respectively. The rates of amphotericin B resistance were 1.1% and 7.6% in C. albicans and C. parapsilosis, respectively. Mortality (14-day and 30-day) rates did not differ between the groups. CONCLUSIONS: A history of CoNS culture positivity in the past month, total parenteral nutrition, and antifungal prophylaxis increases the risk of NAC candidemia.

Introduction: There have been some significant changes regarding healthcare utilization during the COVID-19 pandemic. Majority of the reports about the impact of the COVID-19 pandemic on diabetes care are from the first wave of the pandemic. We aim to evaluate the potential effects of the COVID-19 pandemic on the severity of diabetic ketoacidosis (DKA) and new onset Type 1 diabetes presenting with DKA, and also evaluate children with DKA and acute COVID-19 infection. Methods: This is a retrospective multi-center study among 997 children and adolescents with type 1 diabetes who were admitted with DKA to 27 pediatric intensive care units in Turkey between the first year of pandemic and pre-pandemic year. Results: The percentage of children with new-onset Type 1 diabetes presenting with DKA was higher during the COVID-19 pandemic (p < 0.0001). The incidence of severe DKA was also higher during the COVID-19 pandemic (p < 0.0001) and also higher among children with new onset Type 1 diabetes (p < 0.0001). HbA1c levels, duration of insulin infusion, and length of PICU stay were significantly higher/longer during the pandemic period. Eleven patients tested positive for SARS-CoV-2, eight were positive for new onset Type 1 diabetes, and nine tested positive for severe DKA at admission. Discussion: The frequency of new onset of Type 1 diabetes and severe cases among children with DKA during the first year of the COVID-19 pandemic. Furthermore, the cause of the increased severe presentation might be related to restrictions related to the pandemic; however, need to evaluate the potential effects of SARS-CoV-2 on the increased percentage of new onset Type 1 diabetes.
RESUMEN
BACKGROUND: The aim of this study was to compare chlorhexidine gluconate (CHG)-impregnated dressing and standard dressing with respect to the frequency of central-line-associated bloodstream infection (CLABSI), catheter-related bloodstream infection, primary bloodstream infection, and catheter colonization in critically ill pediatric patients with short-term central venous catheters. METHODS: Children who were admitted to the pediatric intensive care unit of a tertiary institution between May 2018 and December 2019 and received placement of a short-term central venous catheter were included in this single-center randomized controlled trial. Patients were grouped according to the type of catheter fixation applied. RESULTS: A total of 307 patients (151 CHG-impregnated dressing, 156 standard dressing), with 307 catheters (amounting to a collective total of 4,993 catheter days), were included in the study. The CHG-impregnated dressing did not significantly decrease the incidence of CLABSI (6.36 vs 7.59 per 1,000 catheter days; hazard ratio (HR): 0.93, P = 0.76), catheter related bloodstream infection (3.82 vs 4.18 per 1,000 catheter days; HR: 0.98; P = 0.98), and primary bloodstream infection (2.54 vs 3.42 catheter days; HR: 0.79; P = 0.67). The CHG-impregnated dressing significantly decreased the incidence of catheter colonization (3.82 vs 7.59 per 1,000 catheter days; HR: 0.40; P = 0.04). In both groups, the most frequent microorganisms isolated in CLABSI or catheter colonization were Gram-positive bacteria (the majority were coagulase-negative staphylococci). CONCLUSIONS: The use of CHG-impregnated dressing does not decrease CLABSI incidence in critically ill pediatric patients but it significantly reduced catheter colonization. Coagulase-negative staphylococci were the most common microorganisms causing CLABSI or catheter colonization.

OBJECTIVES: To investigate the association between the triggering receptor expressed on myeloid cells-1 (TREM-1) levels and prognosis in septic children. METHODS: Patients admitted to pediatric intensive care units (PICU) of three tertiary centers were included in this prospective observational study. Serum samples were taken at admission from patients who were hospitalized with sepsis. RESULTS: Of the 87 patients included, 34 (39.1%) had severe sepsis and 53 (60.9%) had septic shock. The median age was 2 y (2 mo to 16 y). TREM-1 values were found to be significantly higher in septic shock patients 129 pg/ml (min 9.85- max 494.90) compared to severe sepsis 105 pg/ml (min 8.21- max 289.17) (p = 0.048). Despite higher TREM-1 levels been measured in non-survivors compared to survivors, it was not statistically significant [168.98 pg/ml (min 9.85- max 494.90) vs. 110.79 pg/ml (min 8.21- max 408.90), (p = 0.075)]. CONCLUSIONS: Admission TREM-1 levels were higher in septic shock compared to severe sepsis patients. There was no association between mortality and TREM-1 levels in sepsis. TREM-1 measurements should be used carefully in pediatric sepsis prognosis.

AIM: Experienced surgeons usually prefer early laparoscopic cholecystectomy (ELC) instead of delayed laparoscopic cholecystectomy (DLC) for the treatment of acute cholecystitis (AC). However, the question remains, if ELC is also safe for beginner surgeons. This study compares ELC versus DLC for the treatment of AC as a beginner surgeon approach. MATERIAL AND METHODS: In this prospective randomized clinical trial, patients suffering AC in their first 72 hours of pain were enrolled either in Group L (n:88); patients were treated surgically with ELC immediately or Group D (n:88); patients were first treated medically and than treated surgically with DLC 4-8 weeks later. All operations and medical treatments were done by the same beginner surgeon. RESULTS: In Group L operation time was 60 (50-65) minutes, total hospital stay was 1.5 (1-7) days and total cost was 337.38±78.46 (287-827) USD. In Group D operation time was 50.5 (45-60) minutes, total hospital stay was 5.5(3-15) days and total cost was 499.29±199.38 (321-1506) USD. There were no significant differences regarding to the complications (p>0.05). Hospital stay and total costs were significantly higher in Group D (p<0.001). CONCLUSIONS: This study indicates, that ELC can definitely be chosen as a treatment approach for AC even by beginner surgeons, considering that it reduces hospital stay and total cost.

OBJECTIVES: Anal fissure is a common health problem that affects the quality of life of young patients. The aim of our study was to benchmark results of lateral internal sphincterotomy (LIS) and botulinum toxin injection in the treatment of chronic anal fissure. MATERIAL AND METHODS: This multi-center, retrospective study used data from 135 chronic anal fissure patients. Patients' demographic features, clinical findings, fissure characteristics, post-defecation pain score, rectal bleeding or pruritus, and treatment satisfaction scores were recorded. Patients' data were collected from the hospital records and patients with all of this data available were called and invited to the hospital for examination. RESULTS: Seventy-four LIS and 61 botulinum toxin applied patients were included. Symptom duration, hospitalization period, and duration of remission of complaints after the treatment were significantly higher in the LIS group (p<0.001). However, pruritus in anus and relapses were found to be higher in the botulinum toxin group (p=¬ 0.04 and p= 0.043, respectively). Abscess and fistula were observed in one patient's perianal region in the LIS group, and an abscess was observed in one patient in the botulinum toxin group. There was no significant difference in treatment satisfaction rates and postoperative complications. CONCLUSION: Botulinum toxin yields satisfying results that are comparable to LIS. Patient selection may help mitigate this disease and allow it to be considered a good alternative option to surgery.
RESUMEN
Background and Objectives: Invasive micropapillary carcinoma (IMPC) of the breast is a rare and aggressive variant of invasive ductal carcinoma characterized by high-grade lymphovascular invasion and high rates of nodal metastasis. The prognostic significance of the micropapillary component (MC) ratio that constitutes this aggressive variation is controversial. In this study, we aimed to investigate the effect of the MC ratio on the prognosis of these patients. Methods: The data of 47 patients with IMPC were retrospectively reviewed. Patients were divided into two groups: MC ratio of 10-75% (Group 1) and greater than 75% (Group 2). The demographic characteristics of the patients, histopathologic features of the tumors, and survival rates were compared. Results: We detected no significant difference in demographic characteristics between groups 1 and 2 (p = 0.21). No significant difference was detected in terms of tumor diameter, lymph node metastasis, lymphovascular invasion, histologic grade, multicentricity, local recurrence, distant metastasis, and overall survival. Conclusion: In the micropapillary subgroup of invasive ductal carcinoma, although positive receptor characteristics are directly proportional to the increase in MC ratio, recurrence and survival rates are not affected by micropapillary component level.

Background We aimed to investigate the outcomes of the immediate surgical repair of bile duct injuries (BDIs) following laparoscopic cholecystectomy. Materials and Methods Between January 2012 and May 2017, patients, who underwent immediate surgical repair (within 72 hours) for postcholecystectomy BDI, by the same surgical team expert in hepatobiliary surgery, were enrolled into the study. Data collection included demographics, type of BDI according to the Strasberg classification, time to diagnosis, surgical procedures, and outcome. Results There were 13 patients with a mean age of 43 ± 12 years. Classification of BDIs were as follows: type E in six patients (46%), type D in three patients (23%), type C in two (15%), and types B and A in one patient each (7.6%). Mean time to diagnosis was 22 ± 15 hours. Surgical procedures included Roux-en-Y hepaticojejunostomy for all six patients with type-E injury, primary repair of common bile duct for three patients with type-D injury, and primary suturing of the fistula orifice was performed in two cases with type-C injury. Other two patients with type-B and -A injury underwent removal of clips which were placed on common bile duct during index operation and replacing of clips on cystic duct where stump bile leakage was observed probably due to dislodging of clips, respectively. Mean hospital stay was 6.6 ± 3 days. Morbidity with a rate of 30% ( n = 4) was observed during a median follow-up period of 35 months (range: 6-56 months). Mortality was nil. Conclusion Immediate surgical repair of postcholecystectomy BDIs in selected patients leads to promising outcome.
RESUMEN
BACKGROUND: Liver transplantation (LT) is an important treatment for acute liver failure and end-stage liver disease. Due to the limited supply of livers, there are still thousands of candidates waiting for transplantation in Turkey. We aimed to analyze LT waiting list access by demographics and etiology, particularly the diagnosis of hepatocellular carcinoma (HCC), which has been prioritized for LT in recent years. MATERIALS AND METHODS: Between 2011 and 2018, all patients listed for LT in our center were retrospectively reviewed. Demographic features, etiology of liver disease, waiting time, Model for End-Stage Liver Disease (MELD) score, and survival data were recorded. Differences between the LT group and deceased patients on the waiting list were evaluated. RESULTS: During this period, 266 patients were included in the LT waiting list. Only 119 patients (44.7%) underwent LT (men, 94; women, 25; mean age, 53 years), whereas 103 (38%) died (men, 60; women, 43; mean age, 53 years) in the waiting period. Seventeen patients were status 1A or 1B and of these, 7 patients died from fulminant hepatic failure. MELD score was significantly higher in deceased group (28 ± 7 vs 25 ± 6; P = .014). The frequency of HCC was significantly higher in LT group (29% vs 11%; P = .002). Overall survival of the patients in the waiting list with and without liver transplantation were 63% and 41%, respectively. CONCLUSIONS: HCC is one of the leading etiologies that is considered for cadaveric LT from the waiting list in our center. These patients had slightly lower MELD scores compared to deceased patients with shorter waiting times. We recommend early referral and close monitoring of the patients who are LT candidates.

BACKGROUND: Chronic hepatitis C virus (HCV) infection is a global health problem, and the need for liver transplants is ever-growing. For optimal surgical success, risk factors must be identified and HCV viral load must be reduced to a minimum to avoid complications. In this study, we aimed to investigate the role of HCV viral load on the post-transplant biliary complications. METHOD: Between 2004 and 2018, the cases of 114 liver transplant recipients with HCV infection were retrospectively reviewed. Data collection included demographic variables, preoperative and postoperative amount of serum HCV RNA copies, preoperative diagnosis of hepatocellular carcinoma (HCC), and postoperative biliary complications in the early and late period. After missing values were excluded, the remaining 97 patients were divided into 2 groups according to preoperative HCV RNA status (Group A: HCV RNA [+] and Group B: HCV RNA [-]). RESULTS: Demographic parameters were similar among both groups. There were 67 patients in Group A and 30 patients in Group B. The overall rate of biliary complications was higher in Group A without statistical significance (20% [n = 14] vs 13% [n = 4], respectively, P = .573). Biliary stricture occurrence in the late period was also higher in Group A. In HCC (+) patients (n = 26), biliary complications were significantly higher compared to HCC (-) patients (34% vs 12%, P = .018). However, in patients with biliary complications, the rate of multiple duct anastomoses was higher with no statistical significance (45% vs 26%, respectively, P = .14). CONCLUSION: The biliary complications on patient survival has been previously established, and this is mostly evident in those patients with viral etiology and hepatocellular carcinoma. As was also suggested in our study, hepatocellular carcinoma and positive viral status should be considered as predisposing factors for postoperative biliary complications after liver transplantation. However, the rate of multiple duct anastomoses should also be taken into consideration. New standards of antiviral medications and bridge therapy for HCC may improve transplant outcomes.

PURPOSE: Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease of unknown origin. Although the course of PSC is variable, it frequently is progressive, leading to cirrhosis and requiring a liver transplantation (LT) in more than half of the patients. PSC is the fifth most common indication for LT in the United States and one of the leading indications in Scandinavian countries, whereas PSC affects fewer than 5% of patients undergoing LT in Turkey. In this study, we analyzed our results in the patients with LT owing to PSC. MATERIALS AND METHODS: Between March 2013 and August 2017, all adult patients (>18 years) with LT owing to PSC were analyzed, and clinical data were obtained via retrospective review of patient charts. Demographic features, presence of any concomitant inflammatory bowel disease (IBD), time to LT, and outcome data were recorded. RESULTS: There were 15 patients (8 men and 7 women) with a mean age of 46 ± 13 (age at diagnosis = 36 y). Median time to transplantation was 3 years (range: .5-14 yrs.). All patients had a pretransplant history of IBD. Concomitant cholangiocarcinoma was diagnosed in 1 patient (6.5%). Postoperative complications were observed in 4 patients (26%), and in 2 patients (13%) PSC recurred at a mean of 52 months postorthotopic LT. Disease-free survival and overall survival were 37.3 and 38 ± 21 months, respectively. One of the patients with recurrence and 1 with graft failure owing to rejection died in the follow-up period. CONCLUSIONS: In one single-center study of adults with PSC, we found that all patients with PSC had IBD at diagnosis. The recurrence rate (13%) was comparable to the literature (20% [5.7-59%]). Despite the low frequency of PSC in our clinic, LT in these patients resulted in favorable outcomes regarding postoperative morbidity and mortality compared with other etiologies.

PURPOSE: Estimation of graft volume is critical in living donor liver transplantation (LDLT). In this study, we aimed to evaluate the accuracy of software-aided automated computer tomography (CT) volumetry in the preoperative assessment of graft size for LDLT and to compare this method with manual volumetry. MATERIALS AND METHODS: Forty-one donors (27 men; 14 women) with a mean age in years ± standard deviation (28.4 ± 6.6) underwent contrast-enhanced CT prior to graft removal for LDLT. A liver transplant surgeon determined the weights of liver grafts using automated 3-dimensional volumetry software, and an abdominal radiologist specializing in liver imaging independently and blindly used the commercial interactive volumetry-assisted software on a viewing workstation to determine the liver volume on CT images. Both results were then compared to the weights of actual grafts obtained during surgery. Intraclass correlation coefficients were used to assess the consistency of numerical measurements and Pearson correlation coefficients were calculated to detect a linear relationship between numerical variables. To compare correlation coefficients, z scores were used. RESULTS: Regarding the right and left lobe graft volume estimation by the surgeon, there was a positive correlation between the results and actual graft weight (r = 0.834; P = .001; and r = 0.587; P = .001, respectively). Likewise, graft volume estimation by the radiologist for the right and left lobe was also positively correlated with the actual graft weight (r = 0.819; P = .001 and r = 0.626, P = .001, respectively). There was no significant difference between correlation coefficients (P = .836). CONCLUSION: Volumetric measurement of donor graft using 3-dimensional software provides comparable results to manual CT calculation of liver volume.

PURPOSE: Routine histopathological examination after cholecystectomy for gallstones is performed despite the low rates of incidental findings of malignancy. The aim of this study was to assess predictive values of macroscopic examination of cholecystectomy specimens by surgeons in gallstone disease. METHODS: A prospective multi-center diagnostic study was carried out between December 2015 and March 2017 at four different centers. All patients undergoing cholecystectomy for gallstone disease were consecutively screened for eligibility. Patients whose ages are 18 to 80 years, and preoperative imaging findings without any pathology except cholelithiasis were included. The gallbladder was first evaluated macroscopically ex situ by two operating surgeons and rated as macroscopically benign (group S1), suspicious for a benign diagnosis (group S2), and suspicious for malignancy (group S3). Thereafter, a pathologist made a final histopathological examination whose results are grouped as chronic cholecystitis (group P1), benign or precancerous lesions in which only cholecystectomy is the adequate treatment modality (group P2), and carcinoma (group P3). Diagnostic accuracy of the surgeon's assessment to the histopathological examination was evaluated using sensitivity, specificity, positive and negative predictive values, and accuracy, and correlated by a kappa agreement coefficient. RESULTS: A total of 1112 patients were included in this trial. The specificity rates were 96.5%, 100%, and 98.7% for group S1-group S2, group S1-group S3, and group S2-group S3, respectively. Accuracy rates to detect malignancy were 100% and 95. 2% for group S1 and group S2, respectively. Kappa coefficient values were 1.0 and 0.64 for group S1-group S3 and group S2-group S3, respectively (p < 0.001 for both). CONCLUSION: Assessment of the gallbladder specimen and selective histopathological examination may be adequate after cholecystectomy for gallstone diseases. Such a procedure would have the potential to reduce costs and prevent unnecessary loss of labor productivity without affecting patients' safety. However, higher number of patients in more centers is needed to confirm this hypothesis.

Background. Due to the variations in anatomic location, the identification of parathyroid glands may be challenging. Although there have been advances in preoperative imaging modalities, there is still a need for an accurate intraoperative guidance. Indocyanine green (ICG) is a new agent that has been used for intraoperative fluorescence imaging in a number of general surgical procedures. Its utility for parathyroid localization in humans has not been reported in the literature. Results. We report 3 patients who underwent reoperative neck surgery for primary hyperparathyroidism. Using a video-assisted technique with intraoperative ICG fluorescence imaging, the parathyroid glands were recognized and removed successfully in all cases. Surrounding soft tissue structures remained nonfluorescent, and could be distinguished from the parathyroid glands. Conclusions. This report suggests a potential utility of ICG imaging in intraoperative localization of parathyroid glands in reoperative neck surgery. Future work is necessary to assess its benefit for first-time parathyroid surgery.
