Uncommon causes of acute appendicitis: Retrospective analysis of 6785 histopathological findings in a tertiary center.

BACKGROUND: This study aims to determine the uncommon causes of acute appendicitis in analyzed post appendectomy specimens. METHODS: Histopathology reports of 6785 removed appendices were analyzed retrospectively in order to confirm the uncommon cause of acute appendicitis in single tertiary institution. RESULTS: Unusual cause of acute appendicitis was found in 98 (1.44%) samples (40 female and rest 58 male patients). Neuroen-docrine tumor of the appendix was the most common pathology, followed by serrated adenoma, low-grade appendicular mucinous neoplasm, hyperplastic polyp, and intestinal parasite. In four patients (0.05%), appendicular adenocarcinoma was confirmed with an overall mortality of 75%. Age was significantly higher in uncommon acute appendectomies than in ordinary appendectomies. Survival analysis of unusual appendectomies showed that advanced age is of prognostic importance (Kaplan Meier p<0.0001). There was also a difference in survival between different disease groups in unusual appendectomies, but Cox multifactorial analysis showed that these two factors were not statistically significant. CONCLUSION: Although rare, unusual causes are the etiological factor responsible for acute appendicitis. These reasons should be kept in mind in the older age group and the diagnosis of appendicitis should be made carefully.

The Role of Ductal Lavage Cytology in the Diagnosis of Breast Cancer.

BACKGROUND: Nipple discharge is a common finding which may be a symptom of breast cancer, but it is mostly caused by benign causes. A surgical biopsy followed by a histopathological examination is considered to be the gold standard for the diagnosis of pathological nipple discharge. Non-surgical diagnostic methods should be considered to reduce the need for intervention. Ductal lavage cytology (DLC) is performed by washing and examining the ductal discharge. The usefulness of examining spontaneous discharge is controversial. This study's aim is to evaluate the usefulness in surgical decision-making of ultrasonography (USG), mammography (MMG), magnetic resonance imaging (MRI), ductography, and DLC in patients with pathological nipple discharge. METHODS: Between 2011 and 2018, we retrospectively analyzed 141 patients with pathological nipple discharge who were planned to undergo a surgical procedure and were found to have pathology. In our study, the diagnostic efficiency of DLC for breast cancer diagnosis was compared with USG, MMG, MRI, and ductography. RESULTS: USG was performed in all patients, MMG in 51, MRI in 56, ductography in 46 patients, and cytological samples were taken from 63 patients. Twelve of 17 patients with malignant pathology were reported cytologically as suspected malignancy. The sensitivity of DLC was 70.5% (95% CI: 0.489-0.922), and its specificity was 94.1% (95% CI: 0.862-1.020). CONCLUSION: Numerous studies report that cytology is not adequate for final diagnosis. Negative cytology does not exclude the possibility of malignancy, and positive results do not help in the differential diagnosis.

The importance of the scoring system in Fournier's gangrene.

BACKGROUND: The objective of the study was to investigate risk factors affecting mortality rates in patients with Fournier's gangrene (FG) and develop methods to increase the survival rate. METHODS: We collected data of 73 patients treated for FG between February 2012 and June 2021 at Istanbul Professor Doctor Cemil Tasçioglu City Hospital General Surgery Clinic. The data of living patients (Group 1, n=56) and deceased patients (Group 2, n=17) were analyzed separately. Demographic data of patients were sex, age, infection rate, Uludag FG severity index (UFGSI) scores and FG severity index (FGSI) scores, urea serum levels, the source of infection, the presence of diabetes, obesity, the presence of diversion stoma, duration of vacuum-assisted closure treatment in days, hospitalization time in days, intensive care period in days, and isolated bacterial species. RESULTS: The mortality rate was 23%. A significant difference in age and dissemination score of the infection was found between the two groups. According to UFGSI and FGSI scores, the scores of the two groups of patients were significantly higher. The UFGSI had 100% sensitivity and 68% sensitivity. FGSI had 82% sensitivity and 58% specificity. The cutoff values for UFGSI and FGSI were 8 and 6, respectively. CONCLUSION: Age and dissemination scores of diseases were important factors that cause mortality in patients with FG. However, an accurate scoring system is important in predicting patients to be treated in the intensive care unit (ICU). Patients with a UFGSI score above 8 face a higher risk of death and should be treated in the ICU.

The value of potassium, pH and D-dimer levels in early diagnosis of acute mesenteric ischemia: an experimental study on rats.

INTRODUCTION: The aim of this randomized controlled experimental study was to evaluate the efficacy of potassium, pH and D-dimer levels in blood, as well as potassium and pH levels in peritoneal lavage fluid, in the early diagnosis of acute mesenteric ischemia. MATERIAL AND METHODS: This study was conducted at the Istanbul University Center of Experimental Medicine after having received approval from the Istanbul University animal testing ethics committee. Male albino Wistar rats (n = 24; 250 to 350 g) were divided into two control groups and two ischemic groups. Levels of potassium, pH, and D-dimer in blood and levels of potassium and pH in peritoneal lavage fluid were analyzed for 1 h and 2 h after the induced acute mesenteric ischemia procedure. The degree of ischemic injury was determined using the histopathological damage score in tissue samples taken from the terminal ileum. RESULTS: Ischemic groups had statistically significant differences in potassium and pH in blood and peritoneal lavage fluid compared to non-ischemic groups (p < 0.05). There was no significant difference between control and ischemic groups in terms of D-dimer and histologic grading results after 1 h (p = 0.132, p = 0.475 respectively), while there was a significant difference between control and ischemic groups after 2 h (p < 0.05). CONCLUSIONS: The levels of potassium, pH, and D-dimer could be useful in daily practice for the early diagnosis of acute mesenteric ischemia.

Comparison of Mortality in Fournier's Gangrene with the Two Scoring Systems.

OBJECTIVE: To determine the factors associated with mortality in Fournier's gangrene (FG) toward informing the development of effective treatment strategies. STUDY DESIGN: A descriptive study. PLACE AND DURATION OF STUDY: Department of Surgery, University of Health Sciences, Okmeydani Education and Research Hospital, Istanbul, Turkey, from February 2012 to September 2017. METHODOLOGY: Informations of 30 patients treated for FG were examined retrospectively. The deceased patients (Group 1, n = 8) were analysed separately from the living ones (Group 2, n = 22). Informations in this analysis contained gender, age score, dissemination score, Uludag Fournier's Gangrene Severity Index (UFGSI) and Fournier's Gangrene Severity Index (FGSI) scores, serum levels of urea, infection source, the presence of diabetes, obesity, and other comorbidities, the presence of stoma for diversion, duration of the vacuum-assisted closure treatment, hospitalisation time, intensive care period, and species of bacteria isolated. RESULTS: The overall mortality rate was detected as 26%. A significant difference between the two groups concerning age score of UFGSI parameters was found. The dissemination score of the infection, which is one of the UFGSI parameters, was significantly higher in Group 1 than in Group 2. According to UFGSI and FGSI scores, the scores of group 1 patients were significantly higher. To determine the incidence of mortality, the UFGSI and FGSI had 87.5% sensitivity and had 96% and 91% specificity, respectively. The cut-off values for UFGSI and FGSI were 10 and seven, respectively. CONCLUSION: Based on the findings described in this study, age and dissemination scores from the UFGSI can be used to predict patient outcome. Patients with a UFGSI score greater than 10 have a higher mortality rate.

Neuroendocrine tumor of the appendix: Twelve years of results from a single institution.

BACKGROUND: The aim of this study was to investigate the incidence of appendiceal neuroendocrine tumors (NET) in an acute appendicitis cohort, as well as to investigate the behavioral form of the tumor. Our secondary aim was to investigate survival in patients with appendiceal NET. METHODS: Between February 2006 and June 2018, 6518 appendectomies were performed for acute appendicitis in the department of surgery, University of Health Sciences, Okmeydani Education and Research Hospital, Istanbul, Turkey. The medical records of these consecutive 6518 appendectomy patients were evaluated retrospectively. After the histopathological analysis, a total of 22 patients were identified as cases of appendiceal NET. These patients were included in the study. A retrospective analysis of data including gender, age, intraoperative surgical findings, duration of postoperative follow-up and survival, tumor localization, the diameter of the tumor, tumor grade, invasion, surgical margin, and stage of the tumor was performed. RESULTS: The incidence of appendiceal NET was 0.33%. Eleven patients were diagnosed as primary pathological stage pT1aN0M0 according to the European Neuroendocrine Tumor Society guidelines. One patient was diagnosed as primary pathological stage pT1bN0M0, and 10 patients were diagnosed as primary pathological stage pT2N0M0. The median tumor diameter was 7.6 mm. There was no patient with a tumor diameter greater than 20 mm. CONCLUSION: The incidence of appendiceal NET in our study is consistent with that stated in the literature. The results of our research suggest that further surgical procedures for NETs that occur coincidentally in patients of the AA cohort are often unnecessary. In addition, the study revealed that disease-free survival (100%) was good over a mean follow-up of 59.2 months.

Protective effects of pentoxifylline in small intestine after ischemia-reperfusion.

Objective This study was performed to determine the healing effects of pentoxifylline on molecular responses and protection against severe ischemic damage in the small intestine. Methods Thirty-six Wistar albino rats were divided into six groups. The superior mesenteric artery was clamped for 120 minutes, and reperfusion was performed for 60 minutes. Saline (0.4 mL), pentoxifylline (1 mg/kg), and pentoxifylline (10 mg/kg) were intraperitoneally administered to the rats in the C1, P1, and P3 groups, respectively, 60 minutes before ischemia and to the rats in the C2, P2, and P4 groups, respectively, during reperfusion onset. Malondialdehyde, myeloperoxidase, tumor necrosis factor alpha, interleukin-1 beta, and interleukin-6 in serum and tissue were measured by enzyme-linked immunosorbent assay. Intestinal ischemic injury was histopathologically evaluated by the Chiu score and immunohistochemical staining. Results All serum and tissue molecular responses were significantly blunted in the pentoxifylline-treated groups compared with the controls. Significant improvement in ischemic damage was demonstrated in the pentoxifylline-treated groups by histological grading and immunohistochemical scoring. Conclusions The protective effects of pentoxifylline were confirmed by molecular responses and histopathological examination.

Primary Hydatidosis of the Gluteus Muscle: Report of a Case and Review of the Literature.

Hydatid disease is a parasitic infestation of humans and herbivorous animals, caused by Echinococcus granulosus. A 55-year-old woman had no prior surgery for hydatid disease earlier. Total cystopericystectomy was performed without cyst rupture. Albendazole was given postoperatively. Neither systemic or local complications nor recurrences were found after minimum follow-up of 12 months, and the laboratory test results were within the normal ranges. Since primer muscular hydatidosis is a very rare disease, care should be taken in diagnosis of cystic mass of skeletal muscle, especially in endemic areas.

Bouveret syndrome: A fatal diagnostic dilemma of gastric outlet obstruction.

The patient presented in this study was a 54-year-old woman complaining of nausea and vomiting, onset preceding four days, with no significant past medical history and an unremarkable surgical history. The patient was afebrile and hypertensive. Physical examination revealed a non-tender abdomen, and initial laboratory evaluation revealed elevated blood glucose level, ketonuria, leukocytosis, elevated C-reactive protein, gamma glutamyl transferase, lactate dehydrogenase, and total bilirubin. The patient was admitted to the internal medicine ward due to new onset of diabetes mellitus. Due to persistent nausea and vomiting, gastroscopy revealed a healed duodenal ulcer, and abdominal ultrasonography revealed cholelithiasis. The medical condition of the patient deteriorated further in the internal medicine ward, with impending hypotension, tachycardia, leukocytosis, and acute renal failure, and she was admitted to the intensive care unit due to septic shock. A computerized tomography was obtained, which revealed an impacted gallstone in the distal duodenum. The patient was taken to the operating room. The gallstone was encountered in proximal jejunum immediately distal to the ligament of Treitz. A longitudinal enterotomy was made, and the stone was extracted. Her drains were cleared on postoperative day 5, and gastrointestinal function returned to normal. Unfortunately, the patient developed an overwhelming sepsis due to bacteremia and fungemia, and died on post-operative day 19.

Diagnostic and therapeutic value of ductoscopy in nipple discharge and intraductal proliferations compared with standard methods.

BACKGROUND: Fiberoptic ductoscopy is a practical and direct approach that allows the visualization of intraductal breast disease. The aim of this study was to assess the efficacy of ductoscopy in the diagnosis and management of intraductal lesions. METHODS: Data on 357 ductoscopic investigations from patients with nipple discharge were collected prospectively. Seventy-five patients were diagnosed as having intraductal papillary lesions and these cases were evaluated by final histopathology (55 solitary, 14 multiple papillomatosis, 6 premalignant or malignant lesions). Results of classical diagnostic studies using ultrasonography, mammography, and galactography were compared with those of ductoscopy and pathology. RESULTS: The sensitivities of investigation methods for papillomas in this study were 72 % in ultrasonography, 62.9 % in mammography, 81.4 % in galactography, and 86.6 % in ductoscopy. With ductoscopic papillomectomy (DP), almost 30 % of patient with solitary papilloma did not require further extensive surgery. CONCLUSION: Since there is an increased risk of malignancy, surgical excision is recommended for multiple, larger papillomas and for papillomas with atypia and in addition for papillomas where diagnostic tools produce suspicious findings. On the other hand DP is a minimally invasive intervention and can aid in the follow-up of lesions proven to have no atypia.

Comparison of the Haemodynamic Effects of Three Different Methods at the Induction of Anaesthesia.

OBJECTIVE: Haemodynamic variations are inevitable during induction of anaesthetic drugs. The present study investigates the haemodynamic variations of three different drugs (thiopental, propofol, and etomidate) used for induction of general anaesthesia together with fentanyl. METHODS: In a randomized, double-blind study, 45 patients were assigned to one of three groups (n=15 each). Fentanyl 1 µg kg(-1) was injected over 60 sec followed by propofol 2 mg kg(-1) (Group P), thiopentone 6 mg kg(-1) (Group T), or etomidate 0.3 mg kg(-1) (Group E). Noninvasive measurements of systolic arterial pressure (SAP), diastolic arterial pressure (DAP), mean arterial pressure (MAP), and heart rate (HR) was performed on admittance, immediately before the induction of anaesthesia, and 1, 3, and 5 min thereafter. Cardiac output (CO) values were recorded before induction, immediately after the injection of the drug, and at 1 min after the intubation. RESULTS: In all groups, during the study period, SAP, DAP, MAP, and CO values decreased with respect to time before induction. Following the administration of the induction dose of propofol (Group P), a significantly greater decrease of systolic and diastolic blood pressure was observed with etomidate (Group E) or thiopentone (Group T). Decrease in CO was also more marked with propofol (Group P) than with etomidate (Group E) or thiopentone (Group T). CONCLUSION: It's concluded that, in this study, the combination of fentanyl-etomidate is safer than both the groups of fentanyl-propofol and fentanyl-thiopental in terms of providing haemodynamic stability.

Effect of growth hormone, hyperbaric oxygen and combined therapy on the gastric serosa.

AIM: To investigate the role of growth hormone (GH), hyperbaric oxygen therapy (HBOT) and combined therapy on the intestinal neomucosa formation of the gastric serosa. METHODS: Forty-eight male Wistar-albino rats, weighing 250-280 g, were used in this study. The rats were divided into four groups (n = 12): Group 1, control, gastric serosal patch; Group 2, gastric serosal patch + GH; Group 3, gastric serosal patch + HBOT; and Group 4, gastric serosal patch + GH + HBOT. Abdominal access was achieved through a midline incision, and after the 1-cm-long defect was created in the jejunum, a 1 cm × 1 cm patch of the gastric corpus was anastomosed to the jejunal defect. Venous blood samples were taken to determine the insulin-like growth factor 1 (IGF-1) and insulin-like growth factor binding protein 3 (IGFBP-3) basal levels. HBOT was performed in Groups 3 and 4. In Groups 2 and 4, human GH was given subcutaneously at a dose of 2 mg per kg/d for 28 d, beginning on the operation day. All animals were sacrificed 60 d after surgery. The jejunal segment and the gastric anastomotic area were excised for histological examination. The inflammatory process, granulation, collagen deposition and fibroblast activity at the neomucosa formation were studied and scored. Additionally, the villus density, villus height, and crypt depth were counted and recorded. The measurements of villus height and crypt depth were calculated with an ocular micrometer. New vessel growth was determined by calculatingeach new vessel in a 1 mm(2) area. RESULTS: In the histological comparison of groups, no significant differences were observed between the control group and Groups 2 and 3 with respect to epithelialization, granulation, fibroblastic activity and the inflammatory process, but significant differences were present between the control group and all others groups (Groups 2-4) with respect to angiogenesis (P < 0.01) and collagen deposition (P < 0.05, P < 0.01). Significant differences between the control group and Group 4 were also observed with respect to epithelialization and fibroblastic activity (P < 0.01 and P < 0.05, respectively). There were significant differences in villus density in all of groups compared with the control group (P < 0.05). Crypt depth was significantly greater in Group 4 than in the control group (P < 0.05), but no other groups had deeper crypts. However, villus height was significantly longer in Groups 2 and 4 than in the control group (P < 0.05). The comparison of groups revealed, significant difference between control group and Groups 2 and 4) with respect to the levels of IGF-1 and IGFBP-3 (P < 0.01) 3 wk after the operation. CONCLUSION: HBOT or GH and combined therapy augmented on neomucosal formation. The use of combined therapy produced a synergistic effect on the histological, morphological and functional parameters.

A Case of Traumatic Asphyxia due to Motorcycle Accident.

Background. Perthe's syndrome (traumatic asphyxia) is rare, which is caused by sudden compressive chest trauma and characterized by subconjunctival hemorrhage, facial edema, craniocervical cyanosis, and petechiae on the upper chest and face and should always be kept in mind as a possible complication of injuries of the chest and abdomen. Case Report. In this case report a 36-years-old male patient brought to the emergency room due to thorax trauma related to motorcycle accident was discussed. Distinct cyanotic, edematous, and multiple petechiae were present on the face, neck, and upper thorax regions of the patient. Bilateral subconjunctival hemorrhage was determined. Conclusion. Treatment for traumatic asphyxia is supportive and patient recovery is related to the generally associated injuries. Prognosis of the patients is quite good with effective and timely treatment.

Penetrating cardiac injury: factors affecting outcome.

BACKGROUND: Penetrating cardiac injuries are rare but represent a high mortality. Early recognition of the injury and rapid intervention are necessary. We analyzed the characteristics of patients with penetrating injury and the factors affecting the outcome, including the experience of the general surgeon. METHODS: Twenty-three patients suffering penetrating cardiac injury were retrospectively evaluated in the Istanbul Okmeydani Training and Research Hospital, Department of General Surgery between 1995 and 2009. Patients with no sign of life on admission were excluded. RESULTS: All patients were male, and the median age was 25 years. Fifteen patients had left ventricular, 4 had right ventricular and 4 had right atrial injuries; in addition, 2 patients had accompanying intra-abdominal injuries. No coronary vascular injury was reported, and pericardial tamponade did not statistically influence the outcome. Ten of 23 patients suffering of penetrating cardiac injury were lost, and in 6 of the 10 cases, the patient represented the first experience for the operating surgeon. CONCLUSION: The characteristics of the penetrating cardiac injuries seen in our institution are consistent with the literature. However, we believe that the surgeon's experience is another prognostic factor. Dedicated level 1 emergency services and trained trauma surgeons are invaluable.

Iloprosta reduz o dano colônico na colite isquêmica em ratos / Iloprost reduces colonic injury in ischemic colitis in rats

PURPOSE: Evaluate the effects of iloprost administration in the early period of ischemic colitis and the mechanism that how these effects develop. METHODS: Thirty two Wistar albino female rats with an average weight of 220g were divided into four groups of eight rats. In group 1 the rats were given iloprost and sacrificed after 24 hours and in group 2 they were sacrificed after 24 hours without any iloprost. The rats in group 3 were administrated iloprost and sacrificed after 72 hours and in group 4 they were sacrificed at 72th hour without iloprost. The differences between the groups as tissue damage, vascularization or apoptosis were assessed statistically. RESULTS: Oxidative damage and apoptosis were less pronounced and vascularization was better developed in rats that were given iloprost and sacrificed at 24th hour later in contrast to the rats that were not treated with iloprost. But there was no statistical difference among the groups at 72th hour. CONCLUSION: Iloprost inhibited leucocyte infiltration, decreased proinflammatory cytokines and enhanced angiogenesis so that the oxidative stress and inflammatory response decreased resulting in lesser tissue damage.

OBJETIVO: Avaliar os efeitos da administração de iloprosta no período precoce da colite isquêmica e o mecanismo da evolução destes efeitos. MÉTODOS: Trinta e dois ratos Wistar fêmeas em torno de 220g foram distribuídos em quatro grupos de oito ratos. No grupo 1 administração de iloprosta e sacrificados após 24 horas; no grupo 2 foram sacrificados após 24 horas sem iloprosta; no grupo 3 foi administrado iloprosta e sacrificados após 72 horas; no grupo 4 foram sacrificados após 72 horas sem Iloprosta. As diferenças entre os grupos no referente a dano tecidual. vascularização ou apoptose foi apurada estatisticamente. RESULTADOS: Dano oxidativo e apoptose foram menos acentuados e a vascularização foi melhor nos ratos que receberam iloprosta e sacrificados após 24 horas em contraste com os ratos que não receberam iloprosta. Porém, não houve diferença estatisticamente significante entre os grupos de 72 horas. CONCLUSÃO: Iloprosta inibe infiltração leucocitária, diminui a ação inflamatória de citoquinas e estimula angiogênese resultando em menor dano tecidual.

Effects of glutamine and curcumin on bacterial translocation in jaundiced rats.

AIM: To investigate the effect of curcumin on bacterial translocation and oxidative damage in an obstructive jaundice model and compare the results to glutamine, an agent known to be effective and clinically used. METHODS: Twenty-four female Wistar-Albino rats, weighing 200-250 g, were randomly divided into three groups (8 in each group). After ligation of the common bile duct in all animals, Group I received oral normal saline, Group II received oral glutamine and Group III received oral curcumin for seven days. Blood samples via cardiac puncture, tissue samples (terminal ileum, liver and mesenteric lymph node) and peritoneal fluid were obtained from the animals at the time of death to investigate bacterial translocation and oxidative damage. RESULTS: We observed that both glutamine and curcumin reduced bacterial translocation in blood, hepatocellular damage, plasma cytokine levels, oxidative tissue damage and apoptosis significantly compared to the control group. Additionally, glutamine showed protective effects on ileal epithelium and reduced villus atrophy. CONCLUSION: On the basis of these findings, both curcumin and glutamine are thought to be effective in preventing or reducing bacterial translocation and oxidative damage in obstructive jaundice.

Ductoscopy in the evaluation and management of nipple discharge.

BACKGROUND: Nipple discharge is a relatively common complaint among patients visiting specialized outpatient clinics for disease of the breast. With advancing technology, it became possible to diagnose and manage nipple discharge using minimally invasive procedures. The aim of this study is to report our experience with ductoscopic evaluation of patients with nipple discharge. MATERIALS AND METHODS: Between September 2005 and February 2009, 236 patients with complaint of nipple discharge were admitted prospectively into the study. All patients were evaluated with ductoscopy. Data concerning age, ductoscopic and postsurgical diagnosis, duration, and complications with the procedure were statistically analyzed. RESULTS: For 236 patients evaluated, there were 249 ductoscopic investigations. Of these, 39 patients were found to have intraductal solitary papilloma of which 24 were excised ductoscopically. Of the 24 ductoscopically excised solitary papillomas, it was possible to remove 17 completely, but 7 papillomas could be removed partially. For 13 patients with solitary papillomas large enough or unfavorably localized so that they could not be snare-excised and for 14 patients with multiple papillomas, we offered surgical removal of the lesions by limited excision of the ducts with the help of ductoscopic localization and marking. There were 35 patients who had debris within the canalicular system, and the debris was washed out. Ductoscopy revealed atypical ductal hyperplasia in 3 patients, ductal carcinoma in situ in 6 patients, and invasive carcinoma in 3 patients; all patients underwent surgery. CONCLUSIONS: We believe that, as the technology quickly improves, ductoscopy will become more widely accepted and applied for breast disorders, not only as a diagnostic tool but also as a privileged therapeutic option for certain pathologies.

Meckel's diverticulum manifested by a subcutaneous abscess.

This case report describes an extremely rare complication of a Meckel's diverticulum: enterocutaneous fistula of the diverticulum. The presence of Meckel's diverticulum is a well known entity, but subcutaneous perforation of the diverticulum is very rare. Here we report the case of a patient with the complaint of a right lower quadrant abscess, preoperatively diagnosed as enterocutaneous fistula, which was determined intraoperatively to be a fistula resulting from Meckel's diverticulum.
