RESUMEN
Laparoscopic cholecystectomy (LC) following endoscopic retrograde cholangiopancreatography (ERCP) is the preferred treatment for cholelithiasis with common bile duct stones. However, the optimal timing of LC after ERCP remains controversial. This study aimed to identify the ideal time interval between ERCP and LC. Data from patients who underwent LC after ERCP between November 2016 and August 2022 were retrieved from the electronic medical information system. The patients were categorized into early cholecystectomy (within 72 h of ERCP) and delayed cholecystectomy (after 72 h). The impact of the time interval between ERCP and LC on perioperative outcomes was analyzed. A total of 197 patients were included in the study, with 45 undergoing early cholecystectomy and 152 undergoing delayed cholecystectomy. No significant differences in the preoperative characteristics or operative morbidity were observed between the groups (p = 0.286). However, a significant correlation was found between the time interval from ERCP to LC and the total length of stay (r = -350, p < 0.001). The findings suggest that early cholecystectomy after ERCP is feasible and safe, and performing LC within the first 72 h does not adversely affect postoperative outcomes.
RESUMEN
Objectives: The aim of this study was to evaluate the predictive value of the first postoperative day (POD1) drain fluid amylase in predicting pancreatic fistula formation following pancreaticoduodenectomy (PD). Material and Methods: One-hundred and eighty-five prospective patients undergoing PD between April 2014 and April 2018 were studied retrospectively. Cut-off point to predict the development of POPF was determined by median values for drain fluid amylase of 1883 U/L. Patients were classified into two groups according to POD1 drain fluid amylase values: <1883 U/L (Group 1) and ≥1883 U/L (Group 2). Differences between the groups with clinically relevant POPF and without POPF were evaluated. Results: The incidence of POPF was 17.2%. POD1 amylase level was the strongest predictor of POPF, with levels of higher than 1883 U/L demonstrating the best accuracy (87.5%), sensitivity (78.1%), specificity (89.5%), positive predictive value (60.9%), and negative predictive value (95.1%). One-hundred and forty-four patients (77.8%) had a POD1 drain amylase level of less than 1883 U/L, and POPF developed in only seven (3.7%) cases, whereas in patients with POD1 drain amylase level of 1883 U/L or higher (n= 41), the POPF rate was 31.4% [OR: 22.24, 95% CI (7.930-62.396), p<0.001]. Conclusion: The cut-off point of POD1 drain fluid amylase level (1883 U/L) might predict the clinically relevant POPF with adequate sensitivity and specificity rates in patients undergoing pancreatic resection.
RESUMEN
Benign anorectal diseases such as hemorrhoidal disease, anal fissure, anal pruritus, perianal abscess, and fistula are the most common ones. The aim of this study was to assess sexual function in patients after surgery for benign anorectal diseases. Sixty-one male patients with perianal fistulas, operated on at Department of General Surgery, Faculty of Medicine, completed a self-administered questionnaire including the International Index of Erectile Function (IIEF) score. The median IIEF score of the postoperative patients was significantly higher (24, range [10-25]) than that of preoperative patients (22, range [5-25]), p < .0001. Sexual function is significantly influenced by surgery for benign anorectal diseases.

OBJECTIVE: Rectal cancer is an important cause of mortality and morbidity globally. The aim of this study was to investigate whether the log odds of positive nodes system is a better indicator than tumor node metastasis and lymph node ratio systems to determine rectum cancer prognosis, which is an important cause of mortality and morbidity globally. METHODS: This was a single-center retrospective cross-sectional study. Data were obtained from the medical records of patients with rectum adenocarcinoma followed at Gazi University Hospital. The clinicopathological data of 128 patients with rectum adenocarcinoma who underwent low anterior resection or abdominoperineal resection between January 2010 and December 2018 was retrospectively reviewed. Patients with rectum adenocarcinoma as the first and only primary diagnosis, which was confirmed by histopathological examination, than those who had undergone complete curative resection via low anterior resection or abdominoperineal resection were included. Those with familial adenomatous polyposis or Lynch syndrome, those under 18 years of age, with a synchronous tumor, peritoneal spread, or metastatic disease at the time of diagnosis, and those with <12 lymph nodes dissected from the resection material were excluded from the study. RESULTS: In multivariate analysis, age, perineural invasion, tumor node metastasis stage, lymph node ratio stage, and log odds of positive nodes stage were found to be independent prognostic factors (p<0.05). LODDS2 patients' mortality rates were 9.495 times higher than LODDS0 patients [hazard ratio=9.495, (95%CI 4.155-21.694), p<0.001] while LNR2 stage patients' mortality rates were 7.016 times higher than LNR0 stage patients [hazard ratio=7.016, (95%CI 3.123-15.765), p<0.001] and N2 stage patients had a 5.135 times higher risk of mortality than those who were in N0 stage [hazard ratio=5.135 (95%CI 2.451-10.756), p<0.001]. CONCLUSION: Log odds of positive nodes is a more valuable prognostic factor for rectal cancer patients than tumor node metastasis and lymph node ratio systems to determine rectum cancer prognosis.

RESUMEN
The aim of this study was to perform a descriptive analysis of scientific articles about primary hyperparathyroidism (PHPT) using bibliometric approaches. By analyzing the links between the various research components (authors, journals, institutions, countries) of the academic outputs, it was aimed to summarize the intellectual structure of PHPT, identify recent research trends, and determine the global productivity. Three thousand nine hundred fifty-four articles on PHPT published between 1980 and 2022 were pulled from the Web of Science database and analyzed using bibliometric approaches. Bibliometric network visualization maps were used to identify trending topics, citation analysis, and international collaborations. Spearman correlation coefficient was used for correlation analysis. The 3 most prolific authors are Bilezikian JP. (n = 87), Silverberg SJ. (n = 72) and Akerstrom G. (n = 57). The top 3 most productive institutions were Columbia University (n = 133), Udice French Research Universities (n = 127) and Uppsala University (n = 98). The top 3 most productive journals were Surgery (n = 216), Journal of Clinical Endocrinology and Metabolism (n = 201) and World Journal of Surgery (n = 148). The top 3 contributing countries to the PHPT literature were United States of America (n = 1062, 26.8%), Italy (346, 8.7%) and United Kingdom (274, 6.9%). The most studied topics from past to present are parathyroidectomy, hypercalcemia, parathyroid hormone/adenoma/glands, calcium/calcimimetics, scintigraphy/sestamibi, bone mineral density, ultrasound, vitamin D, osteoporosis, minimally invasive parathyroidectomy, brown tumor, nephrocalcinosis/nephrolithiasis, multiple endocrine neoplasia type 1, normocalcemia, pregnancy, imaging/preoperative imaging, parathyroid cancer/carcinoma, asymptomatic primary hyperparathyroidism, and cinacalcet. The trending topics in recent years were normocalcemic primary hyperparathyroidism, trabecular bone score, children, CDC73, microwave ablation, radiofrequency ablation, denosumab, cinacalcet, preoperative imaging, imaging, diagnosis, CT, PET, PET/CT, 4D/CT, SPECT/CT, F-18-fluorocholine, quality of life, fractures, and metabolic syndrome. We can say that there will be an increasing research trend on PHPT in the coming years. In addition to the Western countries such as the United States and European countries with large economies, Japan and Turkey were also identified as leading countries in the development of the PHPT literature. This study provides significant information about the intellectual structure and global productivity of PHPT to clinicians and other researchers interested on PHPT.

Background: The incidence of retropancreatic lymph node metastasis in gastric cancer patients is not negligible. Aim: The aim of present study was to determine the risk factors for retropancreatic lymph node (LN) metastasis and to investigate its clinical significance. Patients and Methods: Clinical pathologic data of 237 patients with gastric cancer between June 2012 and June 2017 were analyzed retrospectively. Results: 14 patients (5.9%) had retropancreatic LN metastases. The median survival of patients with and without retropancreatic LN metastasis was 13.1 and 25.7 months. According to univariate analysis; tumor size ≥ 8 cm, Bormann type III/IV, undifferentiated type, presence of angiolymphatic invasion, depth of invasion (pT4), N3 stage, No. 3, No. 7, No. 8, No. 9, and No. 12p LN metastasis was found to be associated with retropancreatic LN metastasis. According to multivariate analysis; tumor size ≥ 8 cm, Bormann type III/IV, undifferentiated type, pT4, N3 stage, No. 9 LN metastasis, and No. 12p LN metastasis were found to be independent prognostic variables for retropancreatic LN metastasis. Conclusion: Retropancreatic LN metastasis is a poor prognostic factor for gastric cancer. Tumor size (≥ 8 cm), Bormann type III/IV, undifferentiated tumor, pT4, N3 stage, and No. 9 and No. 12p LN metastasis are risk factors for metastasis to retropancreatic lymph node.
RESUMEN
During liver surgery and transplantation, periods of partial or total vascular occlusion are inevitable and result in ischemia-reperfusion (IR) injury. Nanomedicine uses the latest technological advancement, which has emerged from interdisciplinary efforts involving biomedical sciences, physics and engineering to protect and improve human health. Antioxidant nanoparticles are potential therapeutic agents. The present study investigated the effects of cerium oxide (Co) administration and sevoflurane anesthesia on liver tissue with IR injury. A total of 36 rats were randomly divided into control, Co, IR, IR-Sevoflurane (IRS), Co + IR and Co + IRS groups. In the IR, IRS and Co + IRS groups, hepatic IR was induced. Intraperitoneal Co was administered to the Co groups 30 min before ischemia. Sevoflurane was administered to the IRS and Co + IRS groups during IR injury. Liver tissue samples were examined under the light microscope by staining with hematoxylin and eosin. Thiobarbituric acid (TBARS) levels as well as catalase (CAT) and glutathione-S-transferase (GST) enzyme activity were evaluated in liver tissue samples. The IR group had considerably more hydropic degeneration, sinusoidal dilatation and parenchymal neutrophil infiltration than the Co, IRS, Co + IR and Co + IRS groups. CAT and GST enzyme activity were significantly higher in Co and Co + IR groups compared with the IR group. TBARS levels were significantly lower in Co, IRS, Co + IR and Co + IRS groups compared whit those in the IR group. Intraperitoneal injection of Co with sevoflurane decreased oxidative stress and damage to the liver.
RESUMEN
INTRODUCTION: During liver surgery and transplantation, periods of partial or total vascular occlusion are inevitable and result in ischemia-reperfusion injury (IRI). Nanomedicine uses the latest technology, which has emerged with interdisciplinary effects, such as biomedical sciences, physics, and engineering, to protect and improve human health. Interdisciplinary research has brought along the introduction of antioxidant nanoparticles as potential therapeutics. The goal of this study was to investigate the effects of cerium oxide (CeO2) administration and desflurane anesthesia on liver tissue in liver IR injury. MATERIAL AND METHODS: Thirty rats were randomly divided into five groups: control (C), ischemia-reperfusion (IR), IR-desflurane (IRD), cerium oxide-ischemia reperfusion (CeO2-IR), and cerium oxide-ischemia reperfusion-desflurane (CeO2-IRD). In the IR, IRD, and CeO2-IRD groups, hepatic ischemia was induced after the porta hepatis was clamped for 120 min, followed by 120 min of reperfusion. Intraperitoneal 0.5 mg/kg CeO2 was administered to the CeO2 groups 30 min before ischemia. Desflurane (6%) was administered to the IRD and CeO2-IRD groups during IR. All groups were sacrificed under anesthesia. Liver tissue samples were examined under a light microscope by staining with hematoxylin-eosin (H&E). Malondialdehyde (MDA) levels, catalase (CAT), glutathione-s-transferase (GST), and arylesterase (ARE) enzyme activities were measured in the tissue samples. RESULTS: The IR group had considerably more hydropic degeneration, sinusoidal dilatation, and parenchymal mononuclear cell infiltration than the IRD, CeO2-IR, and CeO2-IRD groups. Catalase and GST enzyme activity were significantly higher in the CeO2-IR group than in the IR group. The MDA levels were found to be significantly lower in the IRD, CeO2-IR, and CeO2-IRD groups than in the IR group. CONCLUSION: Intraperitoneal CeO2 with desflurane reduced oxidative stress and corrected liver damage.

Parathyroid carcinomas are rare endocrine tumors which comprise 0.3-5.6% of all causes of hyperparathyroidism. 90% of them are hormonally active, while 10% of them may be non-functional. They mostly occur in a single parathyroid gland. Concurrent involvement of both parathyroid glands is quite rare. A 57-year-old male patient was admitted to emergency department with the complaint of dyspnea. Thorax tomography revealed a retrosternal mass. The mass was thoracoscopically excised by thoracic surgeons. Histopathological examination result of the mass was reported as parathyroid carcinoma. Parathyroid scintigraphy performed and focal activity increase in the lower pole of the left lobe. Parathyroid hormone level was 118 pg/ml and calcium level was measured as 11.4 mg/dl. The patient with these findings was operated and pathological examination of excised left lower parathyroid tissue was reported as carcinoma. In addition, micropapillary carcinoma was detected in left thyroid lobectomy specimen.Our case was also unusual in that double parathyroid carcinoma, which is a rare condition, was hormonally inactive. We aimed to present our case in the light of the literature due to its rare occurrence.
