Bouveret's Syndrome: A Case-Based Review, Clinical Presentation, Diagnostics and Treatment Approaches
No full textGastric outlet obstruction that arises from gallstones impacted in the distal stomach or proximal duodenum after passing through a cholecystoduodenal, cholecystogastric or rarely choledocoduodenal fistula is called as Bouveret's syndrome and it accounts for approximately 1-3% of all the patients with gallstone ileus. Although treatment modalities, including stone removal or fragmentation with classical endoscopic devices, such as snares, and forceps or fragmentation of gallstones with new devices, such as electrohydraulic lithotripsy, laser, extracorporeal shockwave lithotripsy have been described. However, only 29% of the patients benefit from nonsurgical methods. Removal of the stone through a gastrotomy or enterotomy and performing cholecystectomy and fistula repair with a second operation is an approach recommended for older patients with comorbid diseases. In this paper, a case of Bouveret's syndrome was presented. The authors also aimed to review the diagnosis, management and treatment of this rare disease and to update the previous reviews
Obesity, Hypertrichosis and Sex Steroids: Are these Factors Related to the Pilonidal Sinus Disease?
No full textferhatoglu, m ferhat/0000-0003-1520-7517Objectives: Pilonidal sinus disease causes chronic inflammation of the skin and subcutaneous fatty tissue, and it commonly localises in the sacrococcygeal region. This study evaluated the effects of hypertrichosis, family history, obesity and sex steroids in 298 patients with pilonidal sinus disease. Methods: The medical records of 618 patients treated at the General Surgery Clinic of Malatya State Hospital for primary pilonidal sinus disease between January 2014 and December 2017 were evaluated retrospectively. Results: Female sex and family histories of pilonidal sinus disease and hypertrichosis were significantly higher in patients with than without hypertrichosis (p=0.030, p=0.035, p<0.001). The mean progesterone level was significantly lower in female patients with hypertrichosis than female patients without hypertrichosis (p=0.003). Conclusion: Being overweight or obese, having an occupation that requires long-time sitting and having a family history predisposed to developing pilonidal sinus disease
Perioperative and Postoperative Effects of Preoperative Low-Calorie Restrictive Diets on Patients Undergoing Laparoscopic Sleeve Gastrectomy
No full textObjective A restrictive diet applied before bariatric surgery can be required to reduce the liver volume or as a necessity imposed by insurance companies. However, the benefits of preoperative weight loss remain controversial. The present study aimed to investigate the perioperative and postoperative outcomes of a restrictive diet applied before laparoscopic sleeve gastrectomy. Materials and Methods The data of 128 patients who received surgery in 2015 and 2016 were retrospectively analyzed. All patients were advised to follow a 4-week low-calorie (1000 cal) restrictive diet. Nevertheless, approximately 50% of patients did not accept the diet plan. We divided the patients into two groups as dieters (group 1) and non-dieters (group 2). Results In group 1, changes in after-diet BMI and liver size were statistically significant (p < 0.001). In group 2, mean operation duration, mean hospitalization duration values, mean BMI values, and mean body weight at postoperative 1, 3, 6, and 12 months were statistically significantly higher than in group 1. No statistically significant difference was found between early complication rates of the groups (p = 0.844). Conclusion Low-calorie restrictive diet applied before laparoscopic sleeve gastrectomy has reduced liver volume and shortens surgery and hospitalization time but does not have any significance concerning early complications and weight loss after operation in 1 year. Also, non-adherence of the bariatric surgery candidate patients to the diet seems to be a challenge

Effect of Visceral, Subcutaneous and Retroperitoneal Adipose Tissue on Renal Function After Living Donor Nephrectomy: A Retrospective Analysis of 69 Cases
No full textPurpose: Recent studies reported that the presence of metabolic syndrome is closely correlated with impaired kidney function after living donor nephrectomy. Since the measurement of body mass index cannot differentiate the amount of body adipose tissue from total body weight, body mass index is not a reliable parameter for determining metabolic syndrome. In the present study, we investigated the correlation between body adipose tissue and kidney function recovery following living donor nephrectomy. Materials and Methods: The patients who underwent living kidney donor nephrectomy consequently from July 2016 through December 2017 were enrolled in the study. We preoperatively measured the visceral (VAdT), retroperitoneal (RPAdT), and subcutaneous (SCAdT) adipose tissue volume by a computed tomography scan. Body mass index, adipose tissue measurements, and postoperative estimated glomerular filtration rate (eGFR) were evaluated. Results: The decrease between preoperative eGFR, and the first day, the first month and the sixth month eGFR after surgery were statistically significant (P = .001; P = .001; P = .001, respectively). The negative correlation between VAdT/SCAdT measurements and changes in eGFR at the first and the sixth postoperative month compared to preoperative eGFR were statistically significant (P = .049; P = .041, respectively). Additionally, RPAdT measurements and changes in eGFR at the first and the sixth postoperative month compared to preoperative eGFR (decreasing as RPAdT value increased) were statistically significant (P = .035; P = .026, respectively). Conclusion: According to a preoperative computed tomography scan, VAdT, RPAdT, and VAdT-to-SAdT ratio can predict impaired kidney function recovery. Furthermore, RPAdT measurement is a new variable to predict the impaired kidney function after living donor nephrectomy
A Holistic Assessment of Organ Transplantation Activities, Scientific Productivity on Brain Death in Islamic Countries, and Comparison of the Outcomes with the United Nations Development Statistics
No full textYilmaz Ferhatoglu, Sibel/0000-0001-8726-0996About one-fourth of the world population belongs to the religion of Islam, and a significant number of people in the Muslim society, including health professionals, are dedicated themselves to the holy book Qur'an but unclear about the religious teachings on organ donation and transplantation. These people are dependent on religious rulings declared by ecclesiastical authorities (scholars and imams). In this study, we aimed to question the attitude of Islamic nations on organ donation and transplantation. Secondly, we endeavored to investigate how the Islamic perspective on these issues influences scientific productivity about the subject of brain death, which is undeviatingly related to organ transplantation. The term "brain death" was searched in Thomson Reuters, Web of Science search engine, only including Muslim countries. All of the data obtained were subjected to bibliometric analysis. We also compared the transplantation statistics of Global Observatory on Donation and Transplantation Organization with the development statistics of the United Nations (UN). The two leading Muslim countries in terms of scientific productivity about brain death are Turkey and Iran. Transplantation proceedings is the leading scientific journal on this subject. These two countries have outperformed other Islamic countries in terms of organ donation and transplantation statistics. We also revealed that the human development index and education index of the UN have a positive correlation with the number of deceased transplantation, which is directly related to the number of brain-death-diagnosed cases (r 0.696, p < 0.05 and r 0.771, p < 0.05, respectively). Additionally, we found a positive correlation between expenditure on research and development data of the UN with the number of total transplantations performed and the number of scientific articles on brain death (r 0.889, p 0.01 and r 0.634, p < 0.05, respectively). There is not a consensus about brain death and organ transplantation in Islamic nations, and the majority of these countries have various hindrances about organ donation and transplantation. The legal authorities, health professionals, religious rulers, and media should spend every effort to educate the people on organ donation and transplantation. And, policymakers of Islamic nations should allocate extra funds for education and scientific activities to break down negative views on organ donation and transplantation
Lithobezoar: An Infrequent Cause Of Abdominal Pain, A Case Report And Review Of Literature
No full textA bezoar is the accumulation of indigestible substances in the gastrointestinal system. Presently described is the case of a 47-year-old male patient who was admitted to the clinic with nausea, vomiting, pain, and abdominal distension. He had a medical history of obsessive-compulsive disorder. He had begun eating soil in the previous 3 to 4 months. Gastroscopy revealed a large, solid, claylike mass in the stomach. Surgery was successfully performed to remove the collected soil, but unfortunately, the patient died due to an acute myocardial infarction on the postoperative fourth day. Physicians should keep bezoars in mind in cases of unexplained abdominal symptoms, especially in females and patients with psychiatric disorders. Psychiatric disorders are often ignored by surgeons during examinations, which can lead to serious and life-threatening complications
Prevalence of Left Kidney Vein Entrapment Signs on Computed Tomography Angiography Images of Kidney Donors
No full textBackground: The nutcracker phenomenon (NC-P) is the entrapment of the left kidney vein (LKV) between the superior mesenteric artery and the abdominal portion of the aorta. We aimed to evaluate the frequency of significant left renal vein compression in a healthy population. Materials and methods: The computed tomography angiography images of 131 healthy patients who underwent living kidney donor nephrectomy at our institution were enrolled in this retrospective, descriptive anatomic study. Results: Three (2.3%) cases had severe stenosis, and 26 (19.8) cases had moderate stenosis. The mean aorto-mesenteric angle was narrower in females (p < 0.05). The mean LKV diameter ratio and beak angle were shorter and narrower in females (p < 0.05, p < 0.01, respectively). Thirteen cases (9.9%) showed 3 or 4 positive criteria for NC-P. Younger pateitns and those with body mass index (BMI) < 30 kg/m(2) had increased rates of positive criteria determination (p < 0.05, p < 0.01, respectively). Conclusions: The NC-P criteria were seen with a high frequency in healthy individuals. Female and younger individuals with lower BMI showed a greater prevalence of positive criteria. Revision of the current standards for NC-P with a distinct classification between sex, age, and BMI is required to better assess LKV compression.Science Citation Index Expande
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
