RESUMEN

Emergency surgeries are linked with increased morbidity and reduced life expectancy, often associated with low socioeconomic status, limited access to healthcare, and delayed hospital admissions. While the influence of socioeconomic status on elective surgery outcomes is well-established, its impact on emergency surgeries, including ostomy creation and closure, is less clear. This study aimed to explore how the pandemic and socioeconomic status affect emergency ostomy procedures, seeking to determine which has a greater effect. It emphasizes the importance of considering socioeconomic factors in patient care pathways for ostomy procedures. A total of 542 patients who underwent emergency ostomy formation between 2016 and 2022 were retrospectively analyzed and divided into pre-pandemic and pandemic periods. The pre-pandemic and pandemic periods were compared between themselves and against each other. Demographic data (age and sex), comorbidities, socioeconomic status, etiology of the primary disease, type of surgery, stoma type, length of hospital stay, ostomy closure time, and postoperative complications were retrospectively analyzed for all patients. In total, 290 (53%) patients underwent surgery during the pandemic period, whereas 252 (47%) underwent surgery during the pre-pandemic period. Emergency surgery was performed for malignancy in 366 (67%) patients. The number of days patients underwent ostomy closure was significantly higher in the low-income group (P = .038, 95% CI: 293,2, 386-945). The risk of failure of stoma closure was 3-fold (95% CI: 1.8-5.2) in patients with metastasis. The risk of mortality was 12.4-fold (95% CI: 6.5-23.7) when there was failure of stoma closure. When compared to pandemic period, the mortality risk was 6.3-fold (95% CI: 3.9-10.2) in pre-pandemic period. Pandemic patients had a shorter hospital stay than before the pandemic (P = .044). A high socioeconomic status was significantly associated with early hospital admission for ostomy closure, and lower probability of mortality. More metastases and perforations were observed during the pandemic period and mortality was increased during pandemic and in patients without ostomy closure. The socioeconomic status lost its effect in cases of emergency ostomy creation and had no impact on length of hospital stay in either the pre-pandemic or pandemic period.

RESUMEN

INTRODUCTION: Hemorrhage is a challenging complication of pelvic surgery. This study aimed to analyze the causes, management, and factors associated with morbidity in patients experiencing major pelvic hemorrhage during complex abdominopelvic surgery. METHODS: Patients who had major intraoperative pelvic hemorrhage during complex abdominopelvic surgery at 11 tertiary referral centers between 1997 and 2017 were included. Patient characteristics, management strategies to control bleeding, short- and long-term postoperative outcomes were evaluated retrospectively. RESULTS: There were 120 patients with a mean age of 56.6 ± 2.4 years and a mean BMI of 28.3 ± 1 kg/m2. While 104 (95%) of the patients were operated for malignancy, 16 (5%) of the patients had surgery for a benign disease. The most common bleeding site was the presacral venous plexus 90 (75%). Major pelvic hemorrhage was managed simultaneously in 114 (95%) patients. Electrocauterization 27 (23%), pelvic packing 26 (22%), suturing 7 (6%), thumbtacks application 7 (6%), muscle welding 4 (4%), use of energy devices 2 (2%), and topical hemostatic agents 2 (2%) were the management tools. Combined techniques were used in 43 (36%) patients. Short-term morbidity and mortality rates were 48 (40%) and 2 (2%), respectively. High preoperative CRP levels (p = 0.04), history of preoperative radiotherapy (p = 0.04), longer bleeding time (p = 0.006), and increased blood transfusion (p = 0.005) were the factors associated with postoperative morbidity. CONCLUSION: Postoperative morbidity related to major pelvic hemorrhage can be reduced by optimizing the risk factors. Prehabilitation prior to surgery to moderate inflammatory status and prompt action with proper technique to control major pelvic hemorrhage can prevent excessive blood loss in complex abdominopelvic surgery.

RESUMEN

Herein, we aimed to describe the outcomes of patients with blood stream infections due to carbapenem-resistant Klebsiella pneumoniae (CR-Kp) who received ertapenem plus meropenem combination treatment (EMCT). A total of 53 patients with culture proven CR-Kp bacteremia treated with ertapenem + meropenem were included. The patients with secondary bacteremia due to urinary tract infection exhibited a significantly lower 1-month mortality (OMM), particularly in those with microbiological eradication and those with end-of-treatment success. Salvage EMCT resulted in 49% 1-month survival.

RESUMEN

End-stage renal disease in the human immunodeficiency virus-positive population is increasing. Kidney transplant is the optimal therapy for this population rather than dialysis modalities if some criteria are met. These include undetectable plasma human immunodeficiency virus RNA, CD4 cell count over 200 cells/µL, and the absence of any AIDS-defining illness. Here, we describe the first living-donor kidney transplant in a human immunodeficiency virus-positive recipient in Turkey. The patient, a 52-year-old male diagnosed as human immunodeficiency virus positive, was on antiretroviral therapy, which consisted of 400 mg twice daily darunavir, 100 mg/day ritonavir, and 50 mg/day dolutegravir. He had been negative for human immunodeficiency virus RNA for the past 3 years. The patient developed renal insufficiency without any known cause and started hemodialysis. A living donor transplant from his son was performed, and the patient received ATG Fresenius-S (Neovii Biotech, Rapperswil, Switzerland) induction and a maintenance immunosuppression therapy consisting of methyl-prednisolone, mycophenolate mofetil, and tacrolimus. There were no incidences of delayed graft function or acute rejection. Because of tacrolimus and ritonavir interaction, tacrolimus trough levels were too high. With tacrolimus withdrawn, tacrolimus trough level decreased to detectable levels 2 weeks later. Antiretroviral therapy was continued on the same dosage. At month 4 posttransplant, the patient's creatinine level was 1.01 mg/dL. At present, the patient has had no complications and no episodes of rejection. Kidney transplant is the most favorable replacement therapy for HIV-positive patients who are under controlled AIDS care with highly active antiretroviral therapy. However, drug interactions should be carefully evaluated.

RESUMEN

Objectives: Currently, sphincter-saving procedures are increasingly performed in the treatment of low rectal cancers. This study aimed to evaluate the outcomes of patients who underwent intersphincteric resection. Material and Methods: This was a single-center, retrospective, cross-sectional study. We evaluated the electronic data files of 29 patients who had intersphincteric resections at our institute between 2008 and 2018. Bowel function outcomes were assessed prospectively using Wexner incontinence score. Histopathological, surgical and functional outcomes were analyzed. Results: Mean age of nine female and 20 male patients included in the study was 55.8 ± 12.8 (30-76) years. A tumor-free surgical margin was achieved in all patients. Anastomotic leakage was detected in two patients. Mean Wexner incontinence score of 20 patients who still had functional anastomosis was 8.35, whereas 65% of the patients (n= 13) had a good continence status. There was no relationship between the continence status and sex, tumor distance from anal verge, T stage, distal surgical margin, and lymph node involvement. Twenty-one patients underwent primary coloanal anastomosis and eight patients underwent two-stage coloanal anastomosis. Conclusion: In the treatment of distal rectal cancer, adequate oncological surgery and relatively acceptable functional outcomes can be obtained with intersphincteric resection technique in suitable patients.

RESUMEN

BACKGROUND: The novel coronavirus disease 2019 (COVID-19) has resulted in major changes in health-care systems and emer-gency surgical interventions. Here, we examined patients with acute appendicitis who presented to emergency departments and com-pared diagnosis, treatment, and post-treatment processes before and during the pandemic period and investigated how the pandemic affected management of acute appendicitis. METHODS: A national, multicenter, and cohort study model was designed that included patients older than 18 years of age diag-nosed with acute appendicitis clinically and/or radiologically, with patients compared before (pre-pandemic period: January 1-April 30, 2019) and after (pandemic period: January 1-April 30, 2020) the pandemic. Our investigation included comparisons of pre-operative imaging methods, presence of plastron appendicitis/abscess, conservative/surgical approach, type of anesthesia given, laparoscopic/open surgical approach, bowel resection rates, drain insertion rates, and presence of post-operative complications RESULTS: For the two study groups, 8972 patients from 69 centers were examined, with 4582 patients operated in the pre-pan-demic period and 4234 patients operated in the pandemic period. During the pandemic period, 63.6% of patients underwent open surgery, whereas 34.4% had laparoscopic surgery. Although 60 patients (1.3%) requested non-operative follow-up in the pre-pandemic period, 94 patients (2.2%) requested this in the pandemic period. When conditions of patients were evaluated regardless of their own wishes, 114 patients (2.4%) before and 163 patients (3.8%) during the pandemic received non-operative follow-up. CONCLUSION: Our study did not show the direct correlation between the application of COVID-19-related restrictions and the severity of acute appendicitis. Although non-operative management rates have been increased during the COVID-19 period, the incidences of both complicated and the uncomplicated appendicitis were similar during the COVID-19 crisis period. Given this infor-mation non-operative management can be employed for patients diagnosed with appendicitis.

RESUMEN

BACKGROUND: The optimal timing of surgery following chemoradiotherapy (CRT) is controversial. This trial aimed to assess disease recurrence and survival rates between patients with locally advanced rectal adenocarcinoma (LARC) who underwent total mesorectal excision (TME) after a waiting interval of 8 weeks or less (classic interval; CI) versus more than 8 weeks (long interval; LI) following preoperative CRT. METHODS: This was a phase III, single-centre, randomized clinical trial. Patients with LARC situated within 12 cm of the anal verge (T3-T4 or N+ disease) were randomized to undergo TME within or after 8 weeks after CRT. RESULTS: Between January 2006 and January 2017, 350 patients were randomized, 175 to each group. As of February 2022, the median follow-up time was 80 (6-174) months. Among the 322 included patients (CI, 159; LI, 163) the cumulative incidence of locoregional recurrence at 5 years was 10.1 per cent in the CI group and 6.9 per cent in the LI group (P = 0.143). The cumulative incidence of distant metastasis at 5 years was 30.8 per cent in the CI group and 18.6 per cent in the LI group (sub-HR = 1.78; 95 per cent c.i. 1.14 to 2.78, P = 0.010). The disease-free survival (DFS) in each group was 59.7 and 69.9 per cent respectively (P = 0.157), and overall survival (OS) rates at 5 years were 73.6 versus 77.9 per cent (P = 0.476). CONCLUSION: Incidence of distant metastasis decreased with an interval between CRT and surgery exceeding 8 weeks, but this did not impact on DFS or OS.

RESUMEN

BACKGROUND: Perforations related to endoscopic retrograde cholangiopancreatography (ERCP) are rare but life-threatening complications. The treatment of Type-II-periampullary perforations that develop during endoscopic sphincterotomy remains a topic of discussion. This study aimed to evaluate the usefulness of fully covered self-expanding metal stenting (FCSEMS) for treating Type-II perforations. METHODS: The files of all patients who underwent the ERCP procedures between January 2015 and October 2021 were retrospectively reviewed; patients with Stapher Type-II perforation were included in the current study. Patients with FCSEMS were classified into two groups: those who underwent FCSEMS and those who were conventionally followed up. Moreover, patients with FCSEMS were classified into two subgroups: those who underwent simultaneous stenting and those who underwent late stenting. Mortality, surgical intervention, percutaneous drainage, length of hospital stay, and inflammatory markers were all compared between the groups. RESULTS: Of the 9253 patients undergoing ERCP during the study period, 28 patients (0.3%) were found to have Type-II perforation. The mean age of these patients was 67.7 ± 3.9 years, and 15 patients were female. FCSEMS was performed on 19 patients, whereas 9 patients were on conventional follow-up. None of the patients developed mortality. In the conventional follow-up group, one patient required percutaneous drainage and one required surgical intervention. In contrast, none of the patients in the FCSEMS group required additional intervention. At a statistically significant level, the length of hospital stay was found to be shorter in the FCSEMS group. There was no difference in inflammatory markers between the two groups. In nine patients, FCSEMS was performed simultaneously, whereas, in ten patients, FCSEMS was performed later because they required a second intervention. These two subgroups did not differ in terms of outcomes. CONCLUSIONS: FCSEMS is a safe and effective treatment modality for patients with Type-II perforation. Moreover, it can be safely used in patients whose perforations are diagnosed during the ERCP procedure and in patients whose diagnoses are made after the procedure.

RESUMEN

This study aimed to evaluate the influencing variables for outcomes in patients with septic shock having culture-proven carbapenem-resistant Gram-negative pathogens. It included 120 patients (mean age 64.29 ± 1.35 years and 58.3% female). The mean Sequential Organ Failure Assessment score during septic shock diagnosis was found to be 11.22 ± 0.43 and 9 ± 0.79 among the patients with mortality and among the survivors, respectively (P = 0.017). The logistic regression analysis showed that empirical treatment as mono Gram-negative bacteria-oriented antibiotic therapy (P = 0.016, odds ratio (OR) = 17.730, 95% confidence interval (CI): 1.728-182.691), Charlson Comorbidity Index >2 (P = 0.032, OR = 7.312, 95% CI: 5.7-18.3), and systemic inflammatory response syndrome score 3 or 4 during septic shock diagnosis (P = 0.014, OR = 5.675, 95% CI: 1.424-22.619) were found as independent risk factors for day 30 mortality. Despite early diagnosis and effective management of patients with septic shock, the mortality rates are quite high in CRGNP-infected patients.

RESUMEN

INTRODUCTION: Severe local and systemic tissue injury develop during reperfusion, which is a period during which arterial blood flow and tissue oxygenation are re-established. In this study, we aimed to investigate the anti-inflammatory, antioxidant and protective effects of nesfatin in IR damage developing in liver. MATERIAL AND METHODS: Twenty-four male Wistar-Albino rats were divided to three groups which contained eight rats in all groups. The rats were subjected to 30 minutes of hepatic pedicule occlusion followed by 2h of reperfusion to induce I/R damage. Nesfatin1 (10 µg/ kg) was administered, 30 min prior to ischemia and immediately before the reperfusion period. RESULTS: The findings showed that while the blood levels of AST, ALT and LDH were markedly elevated in the I/R group, they returned to normal levels upon treatment in the Nesfatin group. While IL-1 α, IL-1ß, IL-6, TNF-α and IFN- γ levels in blood and tissue were lower after therapy in the Nesfatin group compared to the I/R group, statistically significant decreases were only noted in IL-1ß, IL-6, TNF-α and IFN- γ levels. TAS levels increased in the treatment group, while upon nesfatin treatment statistically significant decreases were noted in TOS and OSI levels. Histopathological investigations also showed statistically significant decreases in Bax and Caspase-3 staining intensity and the number of stained cells in the Nesfatin group. CONCLUSION: The nesfatin has antioxidant activity and anti-inflammatory effect on improvement of liver functions and histopathological findings in liver ischemia and reperfusion injury. KEY WORDS: Anti-inflammatory, Anti apoptotic Liver ischemia-reperfusion injury, Nesfatin-1.

RESUMEN

<b>Background:</b> Acute mesenteric ischaemia (AMI) is a catastrophic abdominal emergency characterized by sudden critical interruption to the intestinal blood flow which commonly leads to bowel infarction and death. AMI still has a poor prognosis with an in-hospital mortality rate of 50-69 %. This high mortality rate is related to the delay in diagnosis which is often diffucult and overlooked. Early intervention is crucial and the potential for intestinal viability. <br><b>Methods:</b> The charts of 140 patients who were hospitalazed with AMI between May 1997 and August 2013 in Ege University Faculty of Medicine, department of general surgery were retrospectively reviewed. Demographical and clinical features of patients determining the best predictors which effect on morbidity and mortality were evaluated by Multiple Logistic Regression analysis by Enter method after adjustment for all possible confounding factors. <br><b>Results:</b> After Multiple LR analysis by Enter method after adjustment for all possible confounding factors affecting morbidity; shock, exploration and stay in hospital were statistically significant. Age, cardiac comorbidities, ASA scores, the time delay between onset of acute abdominal pain to surgery, the presence of acidosis and shock, the involved organs (small bowel and both), type of surgery and medical treatment and small bowel length under 100 cm were statistically significant on mortality. <br><b>Conclusion:</b> Risk factors related to mortality and morbidity have been poorly analyzed due to lack of prospective studies and smaller number of patients. Early diagnosis generally depends on clinical awareness and suspicion. Age and time of delay between onset of acute abdominal pain to surgery longer than 24 hours are the most important parameters that predict the mortality for patients presenting with shock and acidosis.

RESUMEN

BACKGROUND: Both from a medical and legal point of view, the quality of operative notes are important. In this study we hypothesized that the quality of operation notes could be improved by audit, education session and using a proforma. METHODS: A total of 150 operation notes were audited for compliance with the Royal College of Surgeons guidelines. Results were announced in-clinic training session and guidelines were discussed. An aide-memoire containing guideline parameters placed in the operating theaters. After eight months, operation reports were re-audited on an equal number of patients. An operative note proforma was developed and third audit was carried out. The results of each audit were compared. RESULTS: In the first audit, it was found that fourteen parameters were written with more than 90% accuracy. The first audit revealed seven poor areas in documentation: time of operation (0%), identification of emergency/elective procedure (0%), identification of any prosthesis or devices used (65.3%), details of closure technique (36.6%), name of anesthesiologist (0%), patient position (1.3%), and amount of bleeding (0%). In the second audit there was an incomplete, but significant improvement in these seven parameters (28%, 28.6%, 82%, 75.3%, 31.3%, 32%, and 34% respectively). Following introduction of the proforma; third audit cycle demonstrated a clear improvement in operation note documentation with at least 80% compliance in all parameters. CONCLUSION: This study revealed that the accuracy of the operating room documents can be improved through audits, education of surgeon and using proformas. The use of proforma provides much better results.

RESUMEN

OBJECTIVE: Fine needle aspiration biopsy provides one of the most important data that determines the treatment algorithm of thyroid nodules. Nevertheless, the reliability of fine needle aspiration biopsy is controversial in large nodules. The aim of this study was to evaluate the adequacy of fine needle aspiration biopsy in thyroid nodules that are four cm or greater. MATERIAL AND METHODS: We retrospectively examined 219 patients files who underwent thyroidectomy for thyroid nodules that were greater than four centimeter between May 2007 and December 2012. Seventy-four patients with hyperthyroidism, and 18 patients without preoperative fine needle aspiration cytology were excluded from the study. Histopathologic results after thyroidectomy were compared with preoperative cytology results, and sensitivity and specificity rates were calculated. RESULTS: False-negativity, sensitivity and specificity rates of fine needle aspiration biopsy of thyroid nodules were found to be 9.7%, 55.5%, and 85%, respectively. Within any nodule of the 127 patients, 28 (22.0%) had thyroid cancer. However, when only nodules of at least 4 cm were evaluated, thyroid cancer was detected in 22 (17.3%) patients. CONCLUSION: In this study, fine needle aspiration biopsy of large thyroid nodules was found to have a high false-negativity rate. The limitations of fine-needle aspiration biopsy should be taken into consideration in treatment planning of thyroid nodules larger than four centimeters.

RESUMEN

INTRODUCTION: Paragangliomas are tumors that arise from extraadrenal chromaffin cells and most of them are asymptomatic presenting with painless mass. Retroperitoneal paragangliomas are mostly benign with good prognosis; however, they can present with abdominal pain, palpable mass, or hypertensive episodes. Surgical resection is still the main treatment and necessary for histological assessment. CASE REPORT: A 41 year old female patient presented with 6 months of loss of appetite, weight loss, weakness and breathlessness on exertion.. The patient's initial blood examination showed marked anemia, reduced leukocyte count with neutropenia and lymphopenia and a marked reduction in the platelet count. The patient was admitted for evaluation of her pancytopenia. Magnetic resonance imaging revealed a 8×7×8cm sized mass closed to the pancreatic tail invading splenic hilum. A large mass was identified retroperitoneally, closed to the tail of pancreas with a splenic hilum invasion. Total mass resection and splenectomy was performed. DISCUSSION: Complete surgical excision is the treatment of choice for extra-adrenal paragangliomas as well as for recurrent or metastatic neoplasms. Reactive thrombocytosis is a common cause of thrombocytosis. Splenectomy was found to be one of the main causes of extreme reactive thrombocytosis. Reactive thrombocytosis is a predictable finding after splenectomy and management of the thrombocytosis and prevention of complications should be initiated.

RESUMEN

INTRODUCTION: Metastatic tumors of the pancreas are uncommon and rarely detectable clinically. Metastases to the pancreas are rare. We present a patient with pancreatic metastases from a leiomyosarcoma of the uterus and review the literature about the clinical features of pancreatic metastasis and its surgical management. PRESENTATION OF CASE: A 40-year-old woman, who underwent hysterectomy, left oophorectomy, omentectomy and lymp node dissection for leiomyosarcoma of the uterus. At the follow up, the patient complained of non-specific abdominal discomfort. Preoperative diagnosis were pancreatic pseudocyst, cystadenoma or cystadenocarcinoma. At laparotomy, a cystic mass was found in the tail of the pancreas which was invased to the transverse colon mesenterium and the spleen. Distal pancreatectomy with splenectomy and transverse colon resection was performed. Histologically, the tumor was evaluated as poorly differentiated leiomyosarcoma. DISCUSSION: Metastatic lesions of the pancreas are uncommon and less than 2% of all pancreatic malignancies. However a few cases of leiomyosarcoma with metastases to the pancreas have been reported in the literature. Before deciding that the lesion in the pancreas was metastasis, primary leiomyosarcoma of the pancreas had to be ruled out. Histologically, leiomyosarcoma of the pancreas contains interlacing spindle cells with varying degrees of atypia and pleomorphism. The surgical approach to the pancreatic metastases must be aimed complete excision of the tumor with a wide negative margin of clear tissue and maximum preservation of pancreatic remnant if possible. CONCLUSION: In the absence of widespread metastatic disease, aggressive surgical approach with negative margins must be aimed.

RESUMEN

Introduction. Hydatid disease (HD) is an infestation that is caused by the larval stage of Echinococcus granulosus. The liver is affected in approximately two-thirds of patients, the lungs in 25%, and other organs in a small proportion. Primary retroperitoneal hydatid cyst is extremely rare. The most common complaint is abdominal pain; however, the clinical features of HD may be generally dependent on the location of the cyst. Case Presentation. A 43-year-old female was admitted with the complaint of abdominal pain. Her physical examination was normal. Computed tomography (CT) revealed a 17 × 11 cm cystic lesion, with a thick and smooth wall that is located among the left liver lobe, diaphragm, spleen, tail of the pancreas, and transverse colon and invading the splenic hilum. Total cystectomy and splenectomy were performed. Pathological examination was reported as cyst hydatid. Discussion. Cysts in the peritoneal cavity are mainly the result of the spontaneous or traumatic rupture of concomitant hepatic cysts or surgical inoculation of a hepatic cyst. Serological tests contribute to diagnosis. In symptomatic and large hydatid peritoneal cysts, surgical resection is the only curative treatment. Total cystectomy is the gold standard. Albendazole or praziquantel is indicated for inoperable and disseminated cases. Percutaneous aspiration, injection, and reaspiration (PAIR) technique is another nonsurgical option.
