Posterior fixation of gastric tube with fibrin sealant in laparoscopic sleeve gastrectomy: a promising method to prevent revision surgeries.

BACKGROUND: We aim to assess the effects of gastric posterior fixation with fibrin sealant in laparoscopic sleeve gastrectomy in aspects of 12th-month body mass index and gastric volume. METHODS: The patients who underwent laparoscopic sleeve gastrectomy between January 2019 and February 2021 were divided into two groups preoperatively. The first 75 patients were appointed to the posterior fixation group, and the second 75 were to the control group. Changes in gastric volume and body mass index were assessed in the postoperative 12th month. RESULTS: There were 110 patients in the final analysis. Fifty-four patients had posterior fixation, and 56 had only laparoscopic sleeve gastrectomy. The posterior fixation group was superior in terms of total weight loss rate (39.1% vs. 34.5%, p<0.001) and less gastric volume increase rate (39.8% vs. 164.7%, p<0.001) in the postoperative 12th month. CONCLUSION: Our study suggests that posterior fixation with fibrin sealant in laparoscopic sleeve gastrectomy is a promising method for preventing weight regain and creating a need for revision surgery.

Does the subtotal cholecystectomy rate for acute cholecystitis change with previous endoscopic retrograde cholangiopancreatography?

BACKGROUND: Acute cholecystitis is one of the most common emergent surgeries. As a safe alternative in challenging operations, laparoscopic subtotal cholecystectomy (LSC) is widely used. We questioned whether the results in acute cholecystitis cases changed with a history of endoscopic retrograde cholangiopancreatography (ERCP). When we searched the literature, we could not find a study focusing on the subtotal cholestectomy results in acute cholecystitis. In our study, we aimed to investigate whether the history of ERCP affects the rates of subtotal cholecystectomy (SC) in acute cholecystitis. METHODS: The results of patients (n=470) who underwent surgery for acute cholecystitis at our clinic between 2016 and 2019 were retrospectively evaluated. The patients were divided into two groups according to their history of ERCP. The primary outcome was the SC rate. The secondary outcomes were conversion to open, postoperative complications, serious complications, operative duration, and length of hospital stay. RESULTS: The standard group included 437 patients, whereas the ERCP group included 33 patients. A total of 16 patients underwent SC, with 15 in the standard group and 1 in the ERCP group. There was no significant difference in terms of SC rates between groups (P=0.902). While four cases of operation were completed with conversion to open in the non-ERCP group, no conversion was seen in the ERCP group (P=0.581). No significant differences were detected between the groups in terms of complications, serious compli-cations, operation duration, length of hospital stay, and mortality. CONCLUSION: The results of this study showed that ERCP is not related to an increased rate of SC and conversion in patients with acute cholecystitis. Laparoscopic cholecystectomy for acute cholecystitis can be safely performed in patients with a history of ERCP. LSC is a safe procedure in challenging patients, and fenestrating SC can be preferred to avoid hazardous consequences in such cases.

Analysis of factors related to the decision of Hartmann's procedure and its reversal: a single-center experience.

BACKGROUND: Hartmann's procedure (HP) is commonly applied to resolve acute clinical conditions in most cases with colonic obstruction or perforation. HP and the closure of the end colostomy are associated with high morbidity-mortality rates. In our study, we aimed to report our clinical experience in HP. METHODS: Demographic data and outcomes of Hartmann procedures performed between 2015 and 2023 were retrospectively reviewed. RESULTS: The median age of our study was 63 (18-94) years; 65 of the patients were female, and 97 were male. Colorectal malig-nancies were the primary etiology in 50% of patients who underwent HP, with 70% presenting with obstruction and 30% with perfora-tion. Two-thirds of the patients were American Society of Anesthesiologists-2 or higher. Postoperative complications did not develop in 74.7% of patients. Our mortality rate was 33.3%. The colostomy was closed in 59 patients during an average 2-year follow-up. The median closure time was 311 (57-1319) days. A stapler was used in 89.8% of patients during the closure. A diverting ileostomy was created in only two patients. The median hospital stay was 8 (5-70) days. Post-operative complications did not develop in 25.4% of patients, while four patients died. CONCLUSION: In our population, HP was more commonly performed for colorectal cancer. The procedure and closure of the ostomy result in low stoma closure rates, high morbidity, and mortality rates, as well as surgical difficulties.

Decreased Functioning and Contents of Worries Associated with Anxiety or Depression Symptom Levels Within Patients Hospitalized with COVID-19 Infection.

BACKGROUND: High levels of anxiety and depression symptoms have been reported in patients with COVID-19 compared to the general population. These symptoms were related to variables such as gender, age, and education level with anxiety/depression levels. We aimed to determine the relationship between anxiety and depression symptoms and epidemic-related decreased functioning, worry, and quality of life (QoL). SUBJECTS AND METHODS: The study included 238 hospitalized participants due to COVID-19 and 168 participants who were hospitalized for reasons other than COVID-19. The Hospital Anxiety and Depression Scale (HADS), Short Form 36 (SF-36) QoL Scale, and questionnaires prepared by the researchers were applied. The effects of current worries, impairment in QoL, and decreased functioning during quarantine on levels of anxiety and depressive symptoms were investigated by implementing multiple linear regression analyzes. RESULTS: Our study results suggested the anxiety and depression levels of patients with COVID-19 were not higher than those in the internal medicine inpatient unit at the same time. Worries about transmission to others, uncertainty, social media news, and health anxiety increased the psychiatric symptoms of participants with COVID-19. Disruptions in social relationships and health also have an effect on anxiety/depression symptom levels. Conversely, results indicated losses and worries in occupation and finance did not significantly affect mental symptoms. CONCLUSION: Worries about transmission to others, uncertainty and health anxiety are closely related to anxiety and depression among patients with COVID-19. There is a need for research in the mental health field for the later stages of the pandemic in different cultures.

Investigation of respiratory tract coinfections in Coronavirus disease 2019 infected and suspected cases.

OBJECTIVE: The aim of our study is to determine the risk of coinfection with COVID-19 due to the high prevalence of viral agents in Istanbul in autumn (September, October, and November) and winter (December and January) and to investigate the effects of age, gender, season and clinical features on the development of coinfection with COVID-19. METHODS: In the routine studies of our hospital, COVID-19, reverse transcriptase polymerase chain reaction (RTA kit, Turkiye) and Multiplex PCR Bio-Fire (Bio Merieux Company, France) methods were studied from the nasopharyngeal swab sample and the data were recorded. A total of 400 people with a mean age (7.91±17.80) were included in the study by retrospective scanning. RESULTS: Considering the virus distribution, Respiratory syncytial virus (RSV), COVID-19, rhino/entero virus did not show a significant difference in autumn and winter, while H. metapneumovirus, adeno virus, influenza A significantly higher rates were observed in winter months. Parainfluenza (1, 2, 3, 4) and Corona OC43 were detected at a higher rate in autumn compared to other viruses. Double and triple coinfection rates with other viral agents were high for 2 years and younger. CONCLUSION: The risk of coinfection of COVID-19 with influenza A, RSV, parainfluenza, and rhino/entero virus was found to be higher than other viral agents. Especially in winter, the risk of coinfection with influenza A and COVID-19 increases. In terms of treatment management, coinfection should be investigated in risky patients and influenza a vaccine should be offered to risky groups.

Angiotensin (1-7) peptide replacement therapy with plasma transfusion in COVID-19.

AIM: To determine whether convalescent angiotensin (1-7) peptide replacement therapy with plasma (peptide plasma) transfusion can be beneficial in the treatment of critically ill patients with severe coronavirus 2 (SARS-CoV-2) infection. STUDY DESIGN: Case series of 9 critically ill patients with laboratory-confirmed COVID-19 who met the following criteria: severe pneumonia with rapid progression and continuously high viral load despite antiviral treatment. Peptide plasma: Plasma with angiotensin (1-7) content 8-10 times higher than healthy plasma donors was obtained from suitable donors. Peptide plasma transfusion was applied to 9 patients whose clinical status and/or laboratory profile deteriorated and who needed intensive care for 2 days. RESULTS: In our COVID-19 cases, favipiravir, low molecular weight heparin treatment, which is included in the treatment protocol of the ministry of health, was started. Nine patients with oxygen saturation of 93% and below despite nasal oxygen support, whose clinical and/or laboratory deteriorated, were identified. The youngest of the cases was 36 years old, and the oldest patient was 85 years old. 6 of the 9 cases had male gender. 3 cases had been smoking for more than 10 years. 4 cases had at least one chronic disease. In all of our cases, SARS CoV2 lung involvement was bilateral and peptide plasma therapy was administered in cases when oxygen saturation was 93% and below despite nasal oxygen support of 5 liters/minute and above, and intensive care was required. Although it was not reflected in the laboratory parameters in the early period, 8 patients whose saturations improved with treatment were discharged without the need for intensive care. However, a similar response was not obtained in one case. Oxygen requirement increased gradually and, he died in intensive care process. An increase of the platelet count was observed in all cases following the peptide plasma treatment. CONCLUSION: In this preliminary case series of 9 critically ill patients with COVID-19, administration of plasma containing angiotensin (1-7) was followed by improvement in their clinical status. The limited sample size and study design preclude a definitive statement about the potential effectiveness of this treatment, and these observations require evaluation in clinical trials.

Treatment of COVID-19 patients with quercetin: a prospective, single center, randomized, controlled trial.

Scientific research continues on new preventive and therapeutic strategies against severe acute respiratory syndrome Coronavirus-2 (SARS-CoV-2). So far, there is no proven curative treatment, and a valid alternative therapeutic approach needs to be developed. This study is designed to evaluate the effect of quercetin in COVID-19 treatment. This was a single-centre, prospective randomized controlled cohort study. Routine care versus QCB (quercetin, vitamin C, bromelain) supplementation was compared between 429 patients with at least one chronic disease and moderate-to-severe respiratory symptoms. Demographic features, signs, laboratory results and drug administration data of patients were recorded. The endpoint was that QCB supplementation was continued throughout the follow-up period from study baseline to discharge, intubation, or death. The most common complaints at the time of hospital admission were fatigue (62.4%), cough (61.1%), anorexia (57%), thirst (53.7%), respiratory distress (51%) and chills (48.3%). The decrease in CRP and ferritin levels was higher in the QCB group (all Ps were < 0.05). In the QCB group, the increase in platelet and lymphocyte counts was higher (all Ps were < 0.05). QCB did not reduce the risk of events during follow-up. Adjustments for statistically significant parameters, including the lung stage, use of favipiravir and presence of comorbidity did not change the results. While there was no difference between the groups in terms of event frequency, the QCB group had more advanced pulmonary findings. QCB supplement is shown to have a positive effect on laboratory recovery. While there was no difference between the groups in terms of event frequency, QCB supplement group had more advanced pulmonar findings, and QCB supplement is shown to have a positive effect on laboratory recovery/results. Therefore, we conclude that further studies involving different doses and plasma level measurements are required to reveal the dose/response relationship and bioavailability of QCB for a better understanding of the role of QCB in the treatment of SARS CoV-2.

Treatment of Anastomotic Leaks With EndoVac After Low Anterior Resection in Colorectal Cancers.

INTRODUCTION: Endoscopic drainage should preferably be tried unless the abscess caused by the anastomotic leak is generalized and disseminated into the abdominal cavity. The aim of this study was to evaluate the results of patients treated with EndoVac. PATIENT AND METHODS: The medical records of patients who underwent low anterior resection and were treated using the EndoVac therapy system due to the detection of an anastomotic leak were retrospectively evaluated. RESULTS: Thirty-three of the patients with detection of anastomotic leaks were treated using EndoVac therapy system. The mean number of application of the EndoVac therapy system was 5.8 (1 to 12) for each patient. Mean duration of hospitalization of the patients was 24.5 (9 to 92) days. Five patients underwent a second operation during the follow-up period after application of the EndoVac therapy system. In our study, the number of patients recovering without the need for additional treatment is 30 (30/33). Our success rate was 90.1%. CONCLUSIONS: The EndoVac therapy system is an alternative and helpful system in the treatment of colorectal anastomotic leaks without reoperation needed. It can also prevent permanent stoma.

Over-the-scope clip application for severe gastrointestinal bleeding, leak, or perforation: A single-center experience.

BACKGROUND: Over-the-scope clip (OTSC) devices are now widely used by endoscopists for gastrointestinal bleeding, perforation, or leakage. The present study aims to examine the therapeutic success rate of this technique. METHODS: This was a single-center, retrospective study. In this study, 23 patients with gastrointestinal bleeding, leakage, or perforation were included. The procedure was performed by an experienced endoscopist. RESULTS: Of the patients with an upper gastrointestinal tract defect, six had a perforation and there was one case of anastomosis leakage. Eight patients had a perforation in the lower gastrointestinal tract, and there were two cases of anastomosis leakage. Bleeding was detected in only six patients and all of them were upper gastrointestinal bleeding. Anastomosis leaks, perforations, and bleeding were treated with OTSC and additional procedures. The success rate of OTSC clipping alone was 56.5%. However, the success rate was 86.9% with additional therapeutic procedures (clamp, stent, sclerotherapy). Analysis according to categories of bleeding, perforation, and anastomosis leak revealed that the success rate of the clip application in bleeding was significantly higher than that of perforation or anastomosis leak (p=0.002). The median length of stay in the hospital was five days (min-max: 2-30 days). There were no complications associated with the OTSC procedure. CONCLUSION: OTSC is a safe and effective method for the management of gastrointestinal bleeding, perforation, or anastomosis leak.

Percutaneous cholecystostomy instead of laparoscopy to treat acute cholecystitis during the COVID-19 pandemic period: single center experience.

BACKGROUND: Laparoscopic cholecystectomy (LC) is the accepted standard treatment for acute cholecystitis (AC) in patients eligible for surgery. Percutaneous cholecystostomy (PC) can provide a permanent treatment for high-risk patients for surgery or act as a bridge for later surgical treatment. This study is an evaluation of the use of PC during the current coronavirus 2019 (COVID-19) pandemic at a single hospital. METHODS: Fifty patients with AC were admitted as of the start of the COVID-19 pandemic in Turkey through June 2020. Patients with pancreatitis, cholangitis, and/or incomplete data were excluded from the study. Data of the remaining 36 patients included in the study were recorded and a descriptive statistical analysis was performed. The patients were divided into three groups: PC (n=14), only conservative treatment with antibiotherapy (OC) (n=14), and LC (n=8). The findings were compared with a group of 70 similar patients from the pre-pandemic period. RESULTS: The mean age of the pandemic period patients was 53 years (range: 26-78 years). The female/male ratio was 1.11. PC was preferred in eight (11%) patients in the same period of the previous year, whereas 14 (39%) patients underwent PC in the pandemic period. Four of the 36 pandemic patients were positive for COVID-19, including one member of the PC group. There was one (7.1%) mortality in the pandemic-period PC group due to cardiac arrest. The length of hospital stay between the groups based on the type of treatment was not statistically significant. CONCLUSION: LC is not recommended during the pandemic period; PC can be an effective and safe alternative for the treatment of AC.

A novel survival algorithm in COVID-19 intensive care patients: the classification and regression tree (CRT) method.

BACKGROUND/AIM: The present study aimed to create a decision tree for the identification of clinical, laboratory and radiological data of individuals with COVID-19 diagnosis or suspicion of Covid-19 in the Intensive Care Units of a Training and Research Hospital of the Ministry of Health on the European side of the city of Istanbul. MATERIALS AND METHODS: The present study, which had a retrospective and sectional design, covered all the 97 patients treated with Covid-19 diagnosis or suspicion of COVID-19 in the intensive care unit between 12 March and 30 April 2020. In all cases who had symptoms admitted to the COVID-19 clinic, nasal swab samples were taken and thoracic CT was performed when considered necessary by the physician, radiological findings were interpreted, clinical and laboratory data were included to create the decision tree. RESULTS: A total of 61 (21 women, 40 men) of the cases included in the study died, and 36 were discharged with a cure from the intensive care process. By using the decision tree algorithm created in this study, dead cases will be predicted at a rate of 95%, and those who survive will be predicted at a rate of 81%. The overall accuracy rate of the model was found at 90%. CONCLUSIONS: There were no differences in terms of gender between dead and live patients. Those who died were older, had lower MON, MPV, and had higher D-Dimer values than those who survived.

FICE vs Narrow Band Imaging for In Vivo Histologic Diagnosis of Polyps.

BACKGROUND AND OBJECTIVES: Gastrointestinal cancers are the most frequently occurring cancers worldwide. Diagnosis and removal of polyps during screening endoscopy decreases the prevalence of colon cancer and cancer-related mortality, and it is considered to be the gold standard in gastrointestinal system cancer prevention. Technological innovations in endoscopy have led to revolutionary developments in many areas. Flexible spectral imaging color enhancement (FICE) and narrow-band imaging (NBI) are forms of digital chromoendoscopy and enhance the endoscopic images without the need for a dye. This study seeks to evaluate the efficacy of FICE and NBI on polyp screening and real-time histologic diagnosis with endoscopy and to compare them. METHODS: A total of 134 patients (male/female = 72/62) and 161 polyps were evaluated with FICE or NBI, and real-time histologic diagnosis predictions were classified as neoplastic or nonneoplastic, according to Kudo's pit pattern classification. Pathological results and real-time endoscopic diagnoses were statistically interpreted for both FICE and NBI. Positive predictive value, negative predictive value, sensitivity, specificity, and accuracy rates were calculated and compared for both modalities. RESULTS: When both systems were compared, the negative predictive value of NBI was found to be higher than that of FICE statistically (P < .001). Specificity and positive predictive value in the FICE group were higher than in the NBI group, but the difference was not statistically significant (P = .082 and P = .153, respectively). CONCLUSIONS: Aside from being safe in polyp detection, digital chromoendoscopy also helps the endoscopist in selecting the type of simultaneous intervention (eg, polypectomy, endomucosal resection, or submucosal dissection) by enabling endoscopic histologic diagnosis.

Robotic versus conventional laparoscopic colorectal operations: a-single center experience.

OBJECTIVE: Robotic surgery was first introduced in 2000 especially to overcome the limitations of low rectum cancer surgery. There is still no consensus regarding the standard method for colorectal surgery. The aim of this study was to compare robotic surgery with laparoscopic colorectal surgery. MATERIAL AND METHODS: This is a retrospective study. Data of patients with a diagnosis of colon or rectal cancer were analyzed for robotic colorectal surgery and laparoscopic colorectal surgery. RESULTS: The cost of robotic surgery group was statistically higher than the laparoscopic surgery group (p=0.032). The average operation duration was 178 minutes in the laparoscopic surgery group and 228 minutes in the robotic surgery group, and this difference was statistically significant (p=0.044). There was no statistically significant difference between the groups regarding other parameters. DISCUSSION: Disadvantages of robotic surgery seem to be its higher cost and longer operation duration as compared to laparoscopic surgery. We claim that an increase in the number of cases and experience may shorten the operation time while the increase in commercial interest may decrease the cost disadvantage of robotic surgery.

Plasma calprotectin level: usage in distinction of uncomplicated from complicated acute appendicitis.

BACKGROUND: The aim of this study was to identify the diagnostic role of plasma calprotectin value for a distinction of presence acute appendicitis and the indifference of uncomplicated from complicated acute appendicitis. METHODS: Plasma calprotectin, white blood cell and C-reactive protein values of 89 patients, who have undergone laparoscopic appendectomy between January 2013 and May 2013 were evaluated. RESULTS: Calprotectin was 91 ng/mL (range 45-538) for acute appendicitis and 47 ng/ml (range 28-205) for the control group. There was a positive, statistically significant relation between calprotectin and C-reactive protein values (r = 0. 292 p = 0. 001, respectively). There was no statistically significant difference was determined between calprotectin and white blood cell values (r = 0. 142 p = 0. 187, respectively). CRP and Cal values were significantly higher in patients with a complicated AA group than in those with uncomplicated AA (p = 0. 014, p = 0. 0001, respectively) whereas white blood cell counts did not differ significantly between two groups (p = 0. 164). CONCLUSION: Plasma calprotectin levels were increased in patients with acute appendicitis and should use in a distinction of uncomplicated from complicated acute appendicitis patients.

The marker C-reactive protein is helpful in monitoring the integrity of anastomosis: plasma calprotectin.

BACKGROUND: Despite improved surgical techniques and materials, anastomotic leakage is a big problem for surgeons. The most frequently used laboratory parameters is leukocyte (white blood cell) and C-reactive protein (CRP). Availability of plasma calprotectin with CRP to detect anastomotic leakage was studied. METHODS: In this prospective study of 41 (male/female 18/23) patients in the anastomosis group, 30 (male/female 20/10) patients were included in the control group. The anastomosis groups viewed in preoperatively day and postoperatively 1st, 3rd, and 5th day of CRP, white blood cell, and plasma calprotectin values. RESULTS: Anastomosis group with complications and without complications were studied. Statistically significant similarities between plasma calprotectin and CRP levels in the postoperative period were observed. CONCLUSION: Plasma calprotectin in monitoring the integrity of the anastomosis can be used with a marker CRP.

Serum neural precursor cell-expressed, developmentally down regulated 9 (NEDD9) level may have a prognostic role in patients with gastric cancer.

BACKGROUND: Neural precursor cell-expressed, developmentally down regulated 9 (NEDD9), a member of Crk-associated substrate (CAS) family, is highly expressed in multiple cancer types and involved in cancer cell adhesion, migration and invasion. The prognostic value of NEDD9 has been evaluated before and its expression is a predictor of poor prognosis in cancer patients. The objective of this study was to determine the clinical significance of the serum levels of NEDD9 in gastric cancer (GC) patients. PATIENTS AND METHODS: A total of 68 patients with a pathologically confirmed diagnosis of GC were enrolled into this study. Serum NEDD9 concentrations were determined by the solid-phase sandwich (ELISA) method. Twenty-eight healthy age- and sex-matched controls were included into the analysis. RESULTS: The median age at diagnosis was 60years, range 21 to 84years. Forty-nine (72%) patients were male and cardia was the most common tumor localization (n=37, 77%) in GC patients. The most frequent histologic subtype was adenocarcinoma (n=45, 66%). Liver was the most common metastatic site in 32 patients with metastasis (n=14, 44%). Sixty-one percent of 23 metastatic patients who received palliative chemotherapy (CTx) were CTx-responsive. The median follow-up time was 8months (range 1 to 23months). At the end of the observation period, 17 patients (25%) experienced disease progression and 28 of the remaining patients (41%) died. Median progression-free survival (PFS) and overall survival (OS) of the whole group were 4.0±0.7months [95% confidence interval (CI)=3-5months] and 14.6±1.2months (95% CI=12-17months), respectively. One-year and 2-year OS rates were 54.4% (95% CI=41.3-67.5) and 51.2% (95% CI=37.3-65.1), respectively. The median serum NEDD9 levels of GC patients were significantly higher than controls (1339.51 vs. 1187.91pg/mL, P=0.02). There was no significant difference according to known disease-related clinicopathological or laboratory parameters (P>0.05). Serum NEDD9 levels had a significant impact on PFS (P=0.04). On the other hand, serum NEDD9 levels showed no significantly adverse effect on OS (P=0.50). CONCLUSION: Serum NEDD9 level may be a diagnostic marker for GC patients. Moreover, our study results showed that it was elevated in GC patients and had an unfavorable prognostic effect. However, it has no predictive role on CTx response.

Two Etiological Reasons of Constipation: Anterior Rectocele and Internal Mucosal Intussusception.

Chronic constipation is a common problem in the general population. Rome III criteria can be used for the diagnosis of chronic constipation. The aim of this study is to emphasize the importance of anterior rectocele and mucosal intussusception as two etiological factors for chronic constipation. One hundred patients were included in this study after excluding other causes of the constipation by medical history, physical examination, and laboratory and radiological studies in 108 total patients who were admitted consecutively to the outpatient clinic of the general surgery department of Dr. Sadi Konuk Bakirkoy Education and Research Hospital with the complaint of constipation between June 2009 and January 2010. It was found that 75 % of these patients had anterior rectocele and 66 % of them had internal intussusception which cause chronic constsipation. Anterior rectocele and internal rectal mucosal intussusception must be kept in mind as two significant reasons for chronic functional constipation.
