Purpose The objective of this study is to evaluate the effect of the coronavirus disease 2019 (COVID-19) pandemic on elective and emergent colorectal surgical practice. Methods The population of this retrospective observational study consisted of all consecutive patients who underwent emergent or elective colorectal surgery between March 2019 and March 2021. The patients were divided into 2 groups: the prepandemic group who were treated between March 2019 and March 10, 2020, and the pandemic group who were treated between March 11, 2020 and March 2021. The rate of emergent operations was the primary outcome. The groups were compared based on the frequency of operations, distribution of tumoral features in malignant cases, and 90th-day mortality rates. Results There were 180 and 121 patients in the prepandemic and pandemic groups, respectively. There were significantly more patients of the American Society of Anesthesiologists physical status stage IV with comorbidity in the pandemic group than in the prepandemic group (P = 0.016 and P < 0.001, respectively). The rate of emergent operations was significantly higher in the pandemic group than in the prepandemic group (49.6% vs. 26.7%, P < 0.001). There were significantly more patients who received non-resectional surgery in the pandemic group than in the prepandemic group (P = 0.002). Additionally, there were significantly more patients without resection among patients with a defunctioning stoma (P = 0.001). The length of hospital stay (LoS) was significantly shorter in the pandemic group than in the prepandemic group (P = 0.039). On the other hand, the mortality rate was significantly higher in the pandemic group than in the prepandemic group (15.7% vs. 6.1%, P = 0.011). Conclusion The study findings suggested that the COVID-19 pandemic adversely affected colorectal surgical practices, resulting in more frequent emergent operations, non-resectional procedures with stoma formation, and higher mortality rates.
OBJECTIVE: This study aimed to examine the prognostic effect of the tumor-stroma ratio, which has been shown to have prognostic value in various cancers, in patients with gallbladder cancer who have undergone curative resection. METHODS: The records of gallbladder cancer patients who underwent surgical treatment in our clinic between December 2005 and March 2021 were analyzed retrospectively. The hematoxylin and eosin-stained sections representing the tumors were evaluated under light microscopy to determine tumor-stroma ratio, and based on the results, <50% was defined as the stroma-rich and ≥50% as the stroma-poor groups. RESULTS: A total of 28 patients, including 20 females and 8 males, with a mean age of 64.6 years, were included in this study. Stroma-poor and stromarich tumors were detected in 15 and 13 patients, respectively. There was no statistically significant relationship identified between tumor-stroma ratio and advanced age, gender, serum levels of carbohydrate antigen 19-9 and carcinoembryonic antigen, incidental or nonincidental diagnosis, jaundice, adjacent organ or structure resection, tumor location, grades 1-2 or 3, T1/T2 or T3/T4, N0 or N1/N2, M stage, American Joint Committee on Cancer stage, lymphovascular invasion, and perineural invasion. The stroma-poor and stroma-rich groups had a 5-year survival rate of 30% and 19.2% and a median overall survival of 25.7 and 15.1 months, respectively, with no statistically significant difference between the groups (p=0.526). CONCLUSIONS: A low tumor-stroma ratio tended to be a poor prognostic factor in gallbladder cancer, although not to a statistically significant degree. This can be considered one of the preliminary studies, as further studies involving larger groups are needed.
The aim of this study was to investigate clinicopathologic characteristics, diagnosis, treatment, and prognosis of patients who underwent surgery with a diagnosis of a gastrointestinal stromal tumor (GIST) of the stomach. Methods: In this single center study, the data of a total of 42 patients diagnosed with a GIST of the stomach in our center between 2010 and 2015 were retrospectively analyzed. The mean age was 60.6 years, with a male-to-female ratio of 1.47/1. Patients presented with various complaints (21 patients had stomach pain,14 patients were asymptomatic, 3 patients had hemorrhage, 2 patients had heartburn and acidity,1 patient had intumescence,1 patient had nausea and vomiting), and all patients underwent surgery. The initial diagnosis was made with endoscopy in 19 patients, with computed tomography in 21 patients, and with magnetic resonance imaging in 2 patients. Local excision or wedge resection was performed in 27 patients, whereas subtotal gastrectomy was performed in 15 patients. Results: The mean tumor diameter was 5.66 cm. Pathologically, 25 patients had very low, 5 patients had low, 6 patients had moderate, and 6 patients had high-grade malignancy. The patients with moderate-to high-grade malignancy received imatinib. Liver metastasis occurred in 2 patients. The mean follow-up was 33 months. The mean disease-free survival time was 31.72 months, and the mean disease-specific (n ¼ 2) survival time was 31.25 months. All patients including metastatic ones were still alive. Conclusions: Our study results show that frequent use of imaging studies and increased use of endoscopic scans for various reasons may increase the rate of incidentally detected
Background Exocrine pancreatic insufficiency (EPI) can be seen after bariatric/metabolic surgery. Fecal elastase level is a simple test in diagnosing and grading EPI. Quality of life changes in patients with bariatric/metabolic surgery related to gastrointestinal complaints is debated. Aim This study aimed to investigate rates and grades of EPI via fecal elastase levels and association between EPI and quality of life in bariatric surgery patients. Methods A prospective study was performed for patients with bariatric/metabolic surgery at their second-year follow-up. Fecal elastase levels were used to diagnose and grade EPI as severe or moderate. Patient’s gastrointestinal quality of life index (GIQLI) was calculated. Patients were grouped as sleeve gastrectomy (SG), one-anastomosis gastric bypass (OAGB), single-anastomosis sleeve ileal bypass (SASI), and transit bipartition (TB). Rates of severe or moderate EPI were primary outcome. Secondary outcome was an association between fecal elastase and GIQLI. Results There were 17, 29, 21, and 15 patients in OAGB, SG, TB, and SASI groups. There was no significant difference between groups in GIQLI scores and fecal elastase levels (p = 0.152 and p = 0.361). Rates of patients with moderate EPI in the groups OAGB, SG, TB, and SASI were 23.5%, 17.2%, 14.3%, and 20.0%. GIQLI scores were not significantly correlated with age, postoperative morphometric data, and fecal elastase values (p > 0.05). Conclusion Rates of patients with moderate EPI ranged from 14.3 to 23.5% at second-year follow-up. There was no patient with severe EPI. GIQLI scores were not significantly correlated with fecal elastase levels and different types of bariatric/metabolic surgery. Graphical Abstract
