Aim The effects of conversion to open surgery during laparoscopic resection in rectal cancer on perioperative clinical and long-term oncological outcomes are still controversial. This study aimed to evaluate and compare the impact of conversion to laparoscopic resection for rectal cancer on perioperative and long-term oncological outcomes. Material and methods Between January 2019 and December 2023, 84 consecutive patients who underwent curative surgery for rectal cancer at a single academic center were evaluated retrospectively. Patients were classified and compared as the laparoscopic (LAP-G) and converted (CONV-G) groups. Perioperative, pathological, and long-term oncological outcomes were compared. Results Of the 84 consecutive patients included, 18 were converted to open surgery, leading to a 21.4% conversion rate. Intraoperative blood loss was higher in CONV-G (180 ml vs. 80 ml, p<0.001), but early clinical outcomes were similar in both groups. The median follow-up period was 23.5 (range 3-65) and 30.5 (range 6-61) months in the LAP-G and CONV-G, respectively, and recurrence occurred in 11 (16.7%) and 3 (16.6%) patients, respectively. Three-year overall survival was 96.9% and 89.4% (p=0.609) and 3-year disease-free survival was 92.4% and 83.3% (p=0.881) in LAP-G and CONV-G, respectively, and the results were similar. Conclusion Conversion from laparoscopic rectal resection to open surgery does not have a significant negative impact on morbidity and long-term oncological outcomes., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Purpose: Polymeric clips (Hem-o-lok ligation system) are now widely used to securing the base of the appendix during laparoscopic appendectomy. Studies comparing the use of single or double hem-o-lok clips are limited. The aim of this study was to compare the reliability of a single hem-o-lok clips with a double hem-o-lok clips for closure of an appendiceal stump., Methods: This prospective randomized study includes patients from two centers who underwent laparoscopic appendectomy with the diagnosis of appendicitis between September 2020 and March 2023. Demographic, operative and clinical outcomes of the use of single or double hem-o-lok clips for closure of the appendiceal stump were compared. Factors affecting long postoperative hospital stay were investigated using univariate and multivariate analyzes., Results: One hundred forty two (48.3%) patients in the single hem-o-lok arm and 152 (51.7%) patients in the double hem-o-lok arm were included in the analysis.The shortest operative time was noted in the single hem-o-lok group (52.1 ± 19.9 versus 61.6 ± 24.9 min, p < 0.001). The median hospital stay was 1 day (range 1-10) in the single hem-o-lok group and 1 day (range 1-12) in the double hem-o-lok group, and was shorter in the single hem-o-lok arm (1.61 ± 1.56 vs 1.84 ± 1.69, p = 0.019). Based on multivariate analysis, drain placement was identified as an independent predictive factor for long hospital stay., Conclusions: The use of single hem-o-lok clips for appendiceal stump closure during laparoscopic appendectomy is safe and effective.

Background: The present study aimed to explore the effect of neoadjuvant therapy and tumor regression grade (TRG) on the shrinkage in the distal surgical margin (DSM) induced by formalin fixation in rectal cancer. Materials and., Methods: In this prospective study, the DSM of resected 61 specimens of rectal and rectosigmoid junction adenocarcinoma were measured following fresh and formalin fixation. The measurements were performed within the first 15 min after resection and at 24 h after formalin fixation without pinning and were compared with regard to neoadjuvant treatment status and TRG., Results: In the patients that received neoadjuvant therapy, the fresh and postfixation DSM values were 32.2 mm and 22.7 mm, respectively, and the mean shrinkage rate was 34.7% (P < 0.001). In the patients that did not receive neoadjuvant therapy, the fresh and postfixation DSM values were 54.03 mm and 41.9 mm, respectively, and the mean shrinkage rate was 23.7% (P < 0.001). The mean shrinkage rate was 41.9% in TRG 1, 29.4% in TRG 2, and 31.9 in TRG 3 specimens. The mean shrinkage rate was higher in specimens with a DSM of ≤20 mm compared to specimens with a DSM of >20 mm (46.2% vs. 24.9%)., Conclusion: A complete or near-complete tumor regression in patients with rectal cancer undergoing neoadjuvant therapy increases the shrinkage of DSM. Moreover, this shrinkage rate is likely to be higher and the pathological DSM is likely to be closer than expected in cases that present a better clinical response to neoadjuvant therapy, particularly in distal rectal cancer., Competing Interests: None

Background: Median arcuate ligament syndrome (MALS) is a condition characterised by chronic abdominal symptoms associated with median arcuate ligament (MAL) compression of the coeliac artery., Aim: In this observational study, we aimed to evaluate the outcomes of laparoscopic treatment in patients with MALS., Materials and Methods: The data of ten patients with MALS who were subjected to laparoscopic sectioning of the MAL were retrospectively reviewed. The following data were evaluated: age, gender, clinical and diagnostic test findings, American Society of Anaesthesiologists score, operative findings and complications and mortality, hospital stay duration and hospital readmission. The diagnosis of MALS was established by computed tomography (CT) angiography., Results: Six (60%) of ten patients with MALS were female and four (40%) were male. The mean age was 42.4 ± 12.3. The main symptoms were epigastric pain (100%) and weight loss (60%). CT angiography showed high-grade stenosis of the anterior wall of the proximal coeliac trunk and post-stenotic dilation caused by extrinsic compression of the MAL. Surgical procedure was uneventful in all patients. Operating time was 155.5 min (120-200) and intra-operative blood loss was 150 ml (100-250). Length of stay was 3.1 day (2-9), with no mortality. The post-operative complications developed in two female patients. One of them developed ileus and the other patient developed pulmonary thromboembolism. At 6-month follow-up, all patients were asymptomatic., Conclusion: Laparoscopic decompression is an effective treatment for MALS and can provide symptomatic relief. This method may be the preferred modality of treatment in view of its lack of morbidity and good results., Competing Interests: None

Background: Colonic lipomas begin to be symptomatic when they reach a certain size, although the presentation can vary. In this study, we aimed to evaluate our experiences with the management of patients who presented with symptomatic giant colonic lipomas., Methods: The data of 7 patients with single colonic lipoma were retrospectively reviewed. The following data were evaluated: age, gender, clinical and diagnostic findings, American Society of Anesthesiologists (ASA) score, operative findings, postoperative complications, mortality, hospital stay duration, and hospital readmission. The diagnosis of colonic lipoma was established by computed tomography (CT)., Results: In this study, 4 (57.1%) of 7 patients with colonic lipoma were female, and 3 (42.9%) were male. The mean age was 56.7 years (range, 45-69). The main symptoms were abdominal pain (100%), and constipation (71.4%). The findings of intestinal occlusion detected on CT confirmed the diagnosis in all patients. Colon lipoma was located in the ascending colon in 2 patients, in the hepatic flexure in 2 patients, in the transverse colon in 2 patients, and in the cecum in 1 patient. The surgical procedure was uneventful in all patients. Four (57.1%) patients underwent laparoscopic colonic resection, while in the remaining 3 (42.9%) patients, a laparotomy was performed. The mean operating time was 185.7 min (150-210). Length of stay was 7.1 days (6-10), with no mortality. The mean diameter of the lesions was 7.4 cm (6-9). At a 6-month follow-up, all patients were asymptomatic with no signs of recurrence., Conclusion: Although colon lipomas are rare, they are of great importance because they can be symptomatic and can be confused with colon malignancies in the differential diagnosis. Being able to make a definitive preoperative diagnosis will change the surgical strategy. A minimally invasive surgical approach should be employed to resect symptomatic colonic lipomas with an experienced surgical team in eligible patients whenever possible.

Aim: The present study aimed to investigate the effect of the presence of polyposis in sporadic early-onset colorectal cancer (EOCRC) on clinicopathological and oncological outcomes., Methods: The retrospective study included patients with sporadic colorectal cancer aged 16 to 50 years who underwent curative resection at the general surgery clinics in two healthcare centers between 2013 and 2019. Patients were divided into two groups: polyposis and nonpolyposis. Clinicopathological characteristics and oncological outcomes were compared between the two groups., Results: A total of 127 patients were included, of whom 60.6% were men. There were 25 (19.68%) patients in the polyposis group and 102 (80.31%) patients in the nonpolyposis group. Seventy-one (69.6%) of the nonpolyposis group and 23 (92.0%) of the polyposis group had adenocarcinoma histological types. The total number of patients with mucinous tumor and signet ring cell carcinoma in the nonpolyposis and polyposis groups was 31 (30.4%) and 2 (8.0%), respectively ( p = 0.042). Five-year overall survival (OS) was 60 and 72% in the nonpolyposis and polyposis groups, respectively, and no significant difference was found ( p = 0.332). In univariate analysis, American Joint Committee on Cancer (AJCC) tumor stage (pT) ≥3-4, lymph node positivity, presence of mucinous tumor and signet ring cell carcinoma, lymphovascular invasion, and advanced tumor-lymph nodesmetastasis (TNM) stage (III-IV) were found to be significant negative prognostic factors for OS, whereas none of these parameters were found to be prognostic factors in multivariate analysis. The presence of polyposis was not a significant factor on both univariate and multivariate analyses., Conclusion: Although the sporadic EOCRC cases developing on the basis of polyposis can have slightly better oncological outcomes, these outcomes are mostly similar to those of cases with nonpolyposis., How to Cite This Article: Aday U, Kafadar MT, Oğuz A, et al.

Purpose: The purpose of our study was initially to explore the prognostic role of LDH-to-albumin ratio in patients with colorectal carcinoma (CRC) undergoing curative resection., Methods: The retrospective study included 295 CRC patients that underwent curative resection. According to time-dependent receiver operating characteristics (ROC) analysis, the optimal cutoff value for pretreatment LDH-to-albumin ratio was 52.7. Cox regression univariate and multivariate analyses were utilized to analyze the prognostic factors for disease-free survival (DFS) and overall survival (OS)., Results: The 295 participants included 117 women (39.7%) and had an overall mean age of 55.8 ± 14.1 years. The median follow-up period was 31.8 ± 21 months (range, 6-78 months) and 53 patients (18.0%) died from cancer during the follow-up period. The 5-year DFS and OS rates were 65.4% and 68.5% in patients with LDH-to-albumin ratio <52.7 (n = 152), and were 55.2% and 55.4% in patients with LDH-to-albumin ratio ≥52.7 (n = 143), respectively. Kaplan-Meier curves showed that LDH-to-albumin ratio ≥52.7 was significantly associated with worse DFS and OS (P = 0.003 and P < 0.001, respectively). Multivariate analyses revealed that LDH-to-albumin ratio was an independent predictor of resectable CRC (odds ratio, 2.104; 95% confidence interval, 1.112-3.982; P = 0.022)., Conclusion: Our study revealed that high pretreatment LDH-to-albumin ratio level was an unfavorable prognosticator in patients with CRC undergoing curative resection. LDH-to-albumin ratio is a candidate to be a prognostic biomarker in clinical practice., Competing Interests: Conflict of Interest: No potential conflict of interest relevant to this article was reported., (Copyright © 2020, the Korean Surgical Society.)

Aim of the Study: To investigate the prognostic role of lactate dehydrogenase-to-albumin ratio (LAR) in gastric cancer patients undergoing curative resection., Material and Methods: A retrospective study was conducted including resectable gastric cancer patients. According to the time-dependent receiver operating characteristics (ROC) analysis, the optimal threshold for pretreatment LAR was 5.5. The Kaplan-Meier method, Cox regression univariate and multivariate analyses were used to analyze the prognostic factors for disease-free survival and overall survival (OS)., Results: The study cohort consisted of 81 patients, mean age was 60.2 ±13.8 (range, 29-87) years and 55 (67.9%) were male. The median OS time was 34.8 and 45 months in patients with LAR ≥ 5.5 ( n = 50) and LAR < 5.5 ( n = 31), respectively. Kaplan-Meier curves showed that with the increase in LAR there was reduced survival, but it was not statistically significant ( p = 0.278). Multivariate analyses revealed that the positive lymph node ratio above 20% was an independent predictor in resectable gastric cancer patients (OR = 6.281, 95% CI: 1.135-34.767, p = 0.035)., Conclusions: With the increase in LAR survival in gastric cancer decreased, but it was not statistically significant. Studies involving a large patient series are needed., Competing Interests: The authors declare no conflict of interest., (Copyright © 2020 Termedia.)

Introduction: Whether complete splenic flexure mobilization (SFM) is required remains a controversial issue and there are numerous approaches regarding the performance of this procedure., Aim: To investigate the effect of SFM performed with a medial-to-lateral and superior-to-inferior approach on early clinical outcomes in laparoscopic resection of rectal cancer., Material and Methods: The SFM procedure was initiated by the ligation of the inferior mesenteric vein followed by dissection extending from the upper border of the pancreas to the splenic hilum through the gastrocolic space. The mesocolon was dissected in a superior-to-inferior and medial-to-lateral fashion and the presacral space was entered by dividing the inferior mesenteric artery. The procedure was completed by dividing all the splenocolic, phrenicocolic, gastrocolic, and pancreaticomesocolic ligaments., Results: A total of 43 patients were included in the study, comprising 26 (60.5%) men and 17 (39.5%) women with a mean age of 58.2 ±13.9 (range: 30-87) years. Of the 43 patients, 21 (48.8%) underwent neoadjuvant chemotherapy and a diversion stoma was performed in 37 (86%) patients. No adjacent organ injury occurred intraoperatively. Mean operative time was 271 ±50 min and mean blood loss was 144 ±83 ml. One (2.3%) patient might have developed anastomotic leakage secondary to bevacizumab therapy postoperatively and developed no anastomotic stenosis in the follow-up period. Mean length of hospital stay was 9.3 ±4.3 days and no mortality occurred in any patient., Conclusions: Splenic flexure mobilization performed via the superior-to-inferior and medial-to-lateral approach appears to be a safe and feasible procedure., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2019 Fundacja Videochirurgii.)

Background: Timing and adequacy of peritoneal source control are the most important pillars in the management of patients with acute peritonitis. Therefore, early prognostic evaluation of acute peritonitis is paramount to assess the severity and establish a prompt and appropriate treatment. The objectives of this study were to identify clinical and laboratory predictors for in-hospital mortality in patients with acute peritonitis and to develop a warning score system, based on easily recognizable and assessable variables, globally accepted., Methods: This worldwide multicentre observational study included 153 surgical departments across 56 countries over a 4-month study period between February 1, 2018, and May 31, 2018., Results: A total of 3137 patients were included, with 1815 (57.9%) men and 1322 (42.1%) women, with a median age of 47 years (interquartile range [IQR] 28-66). The overall in-hospital mortality rate was 8.9%, with a median length of stay of 6 days (IQR 4-10). Using multivariable logistic regression, independent variables associated with in-hospital mortality were identified: age > 80 years, malignancy, severe cardiovascular disease, severe chronic kidney disease, respiratory rate ≥ 22 breaths/min, systolic blood pressure < 100 mmHg, AVPU responsiveness scale (voice and unresponsive), blood oxygen saturation level (SpO 2 ) < 90% in air, platelet count < 50,000 cells/mm3, and lactate > 4 mmol/l. These variables were used to create the PIPAS Severity Score, a bedside early warning score for patients with acute peritonitis. The overall mortality was 2.9% for patients who had scores of 0-1, 22.7% for those who had scores of 2-3, 46.8% for those who had scores of 4-5, and 86.7% for those who have scores of 7-8., Conclusions: The simple PIPAS Severity Score can be used on a global level and can help clinicians to identify patients at high risk for treatment failure and mortality., Competing Interests: Competing interestsThe authors declare that they have no competing interests.

Objectives: With the widespread use of esophagogastroduodenoscopy (EGD) in recent years, upper gastrointestinal system polyps have started to be encountered more often. Although most patients with gastric polyps are asymptomatic, these are important due to their malign potential, and gastric cancer may develop if left untreated., Material and Methods: Records of 12.563 patients who underwent EGD at Kartal Kosuyolu High Specialization Health Application and Research Center for any reason between January 2013 and June 2016 were reviewed retrospectively. Patients with at least 1 histopathologically proven polyp were included in this study., Results: A total of 12.563 endoscopic procedures of the upper gastrointestinal system were investigated and 353 (2.8%) polypoid lesions were detected. Mean age of these patients was 56.3 years and 241 (68.3%) of the patients were female. Gastric polyps were found most commonly in the antrum (50.1%) and of all gastric polyps, 245 (69.5%) were less than 1 cm. Histopathological evaluation showed that hyperplastic polyp (HP) (n= 151, 42.8%) was the most common polyp type, followed by fundic gastric polyp (FGP) (n= 51, 14.4%). Non-polyp gastric mucosa evaluation of 298 patients revealed that 34.9% of the cases were Helicobacter pylori positive, 19.4% had intestinal metaplasia, and 11.4% had atrophic gastritis., Conclusion: Polyps of the upper gastrointestinal system are generally detected coincidentally as they have no specific symptoms. Polypectomy is required for gastric polyps because of their potential for malign transformation according to medical evidence., Competing Interests: Conflict of Interest: The authors have no conflicts of interest to declare., (Copyright © 2019, Turkish Surgical Society.)

Introduction: Trauma is the most frequent cause of splenic rupture. In contrast to traumatic rupture of the spleen, spontaneous splenic rupture (SSR) is a rare and life-threatening condition., Aim: To present the cases of patients with SSR, who had no history of trauma, and who had been receiving anticoagulant and/or antiaggregant treatment while hospitalised for cardiac reasons., Material and Methods: The cases of 6 patients with SSR at Gastroenterological Surgery Department, Kartal Koşuyolu High Speciality and Training Hospital were retrospectively evaluated. The clinicodemographic factors and the diagnostic and therapeutic methods utilised for these patients with SSR while hospitalised were investigated as well., Results: Five (83.3%) of the patients were male and 1 (16.6%) was female. The median age of the patients was 71 (61-73) years. Three of the patients had only been receiving antiaggregant treatment, while 2 had only been receiving anticoagulant treatment; only 1 patient had been receiving both anticoagulant and antiaggregant treatments. The decrease in haematocrit (HCT) levels ascertained on the day of SSR diagnosis and the HCT levels ascertained on the day of hospitalisation were statistically significant. All the patients received a blood transfusion. While 5 (83.33%) of the 6 patients had splenectomy, 1 (16.66%) patient received conservative treatment. Mortality was seen in 4 (66.6%) patients., Conclusions: Spontaneous splenic rupture is a condition that should be taken into consideration in the differential diagnosis of patients hospitalised for cardiac reasons, who are receiving anticoagulant and/or antiaggregant treatment in cases of newly developed abdominal pain and low HCT levels., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2019 Termedia Sp. z o. o.)

Introduction: Anatomical changes after surgery and fibrotic adhesions increase the organ laceration risk, including that of the ureter, in recurrent cases and secondary operations. The aim of this study was to investigate the changes in the anatomical localisations of the ureters via computed tomography urography in patients undergoing rectal cancer surgery., Material and Methods: The study involved prospectively collected data on the changes of ureteral location preoperatively and postoperatively in patients with operated rectal cancer. Distances (mm) of ureters determined midline in the computed tomography urogram phase., Results: A total of 18 patients were included. The mean distances between the right ( R 1 ) and left ( L 1 ) ureters and the mid-vertebral line before the surgery were 30.9 ±5.4 mm and 34.5 ±9.9 mm, respectively. The postoperative distances between them ( R 2 and L 2 ) were 26.4 ±9.1 mm and 29.5 ±9.9 mm, respectively. The R 2 measurement showed that 83.3% (15/18) of the right ureters had deviated medially, whereas 16.7% (3/18) of them had deviated laterally. The L 2 measurements showed that 88.8% (16/18) of the left ureters had deviated medially, whereas 11.2% (2/18) of them had deviated laterally. The differences between the preoperative and postoperative measurements of the right and left ureter positions were 4.5 ±9.2 mm and 4.9 ±4.6 mm, respectively, with the displacement in the left ureter being statistically significant ( p ≤ 0.001)., Conclusions: Rectal cancer surgery causes medially deviated changes in the positions of the ureters., (Copyright: © 2019 Termedia Sp. z o. o.)

Objective: Esophagojejunal anastomotic leakages, which occur in the reconstruction procedures performed after total or proximal gastrectomy, still account for one of the most significant causes of morbidity and mortality in spite of the developments seen in the perioperative management and surgical techniques in gastric cancer surgery. The aim of the presentstudy was to ascertain the risk factors for Esophagojejunal anastomotic leakages., Materialand Methods: A total of 80 patients with gastric cancer, who had total gastrectomy + D2 lymph node dissection and Esophagojejunal anastomotic between January 2013 and December 2016, were retrospectively evaluated. Patients who did not have anastomotic leakages during their clinical follow-ups were allocated to Group 1, whereasthose who had anastomotic leakages were allocated to Group 2., Results: A total of 58 (72.5%) out of 80 patients were males, whereas 22 (27.5%) were females.The mean age of the patients was 61.2±11.2 years. There were no demographic differences between the groups. Postoperative recurrent fever (p=0.001), C-reactive protein values on postoperative days 3 and 5 (p=0.01), and neutrophil-to-lymphocyte ratio on postoperative day 5 (p=0.022) were found to be statistically significant with regardto Esophagojejunal anastomotic leakages and other postoperative complications. The duration of operation (p=0.032) and combined organ resection (p=0.008) were ascertained as risk factors for Esophagojejunal anastomotic leakages., Conclusion: Surgeons should be careful about Esophagojejunal anastomotic leakages thatare significant postoperative complications seen especially in cases where the duration of operation is prolonged, and additional organ resections are performed. Recurrent fever, high C-reactive protein levels, and neutrophil-to-lymphocyte ratio may serve as warnings for complications in postoperative follow-ups.

Objective: The aim of this study was to investigate the effects of ruptured aneurysm on morbidity and mortality in patients with ischemic colitis (IC) and resection following infrarenal abdominal aortic aneurysms (AAA) surgery., Methods: Between January 2012 and December 2016, patients who underwent resection for ischemic colitis in our clinic were retrospectively reviewed. Data on the ruptured condition of the aneurysm, the emergency or elective form of aneurysm surgery, treatment method for the aneurysm (EVAR-open) were obtained. The patients were compared and divided into two groups as those with ruptured aneurysm and those without., Results: A total of 275 infrarenal AAA cases were treated by the cardiovascular surgery clinic between January 2012 and December 2016. Fourteen patients (5%) developed ischemic colitis requiring resection. Four (1.8%) patients with EVAR and 10 (17.5%) patients with open surgery were operated because of IC. No statistically significant difference was observed between the two groups in terms of demographic data and surgical procedures. The intergroup comparison did not reveal any statistically significant difference among gastrointestinal (GIS) symptoms, the time period until surgery, the involved colon segment, and the surgical procedures performed. The mortality rate in ruptured AAA group was 83.3%, while it was 62.5% in the non-ruptured AAA group. In spite of the fact that the mortality rate was high in the ruptured group, it was not statistically significant (p=0.393)., Conclusion: IC is a complication of AAA surgery with a high mortality rate. Rupture in abdominal aortic aneurysm increasing mortality in IC patients. This complication with a high mortality rate following open AAA surgery should be noted by surgeons and we believe that the liberal utilization of laparotomy and early intervention in suspected cases will decrease mortality rates., Competing Interests: Conflict of Interest: The authors declare no conflict of interest.

Introduction: Situs inversus totalis (SIT) is a very rare condition that is seen at a rate of one in about 6000-8000 births., Aim: To offer a general view on the coexistence of SIT and gastric cancer, accompanied by a literature review., Material and Methods: Within the scope of this study, the case of a patient with gastric adenocarcinoma and SIT has been presented. Previous research on gastric cancer cases with SIT was reviewed through a comprehensive search of the PubMed, Medline, and Google Scholar databases. The keywords used to conduct this research were "situs inversus totalis and gastric cancer," "situs inversus totalis and gastric malignant," and "situs inversus totalis and gastric resection." The database search covered English studies published between 2000 and 2016., Results: The results of our literature review revealed 20 studies of patients with gastric cancer and SIT, and 21 related cases. Overall, 12 of the patients were male, 9 were female, and their mean age was 61.8 ±10.97 years. The vascular assessment data showed that three out of the 13 mentioned cases had vascular anomalies. Eleven of the patients had laparoscopic resections, and one of the patients that had a surgical procedure exhibiting a postoperative mechanical obstruction., Conclusions: The coexistence of SIT and gastric cancer is a very rare condition, and a careful preoperative radiological assessment should be conducted because there can be accompanying vascular anomalies. Laparoscopies and robotic surgeries can be performed for suitable patients at experienced centres, consistent with oncological principles.

Objective: Our aim in this study was to present the cases of our patients who contracted colonic perforation during elective colonoscopy and became emergency cases; we also discuss treatment modalities along with literature reports on the subject., Material and Methods: Cases of patients who contracted iatrogenic colonic perforation following endoscopy of the colorectal system between January 2009 and December 2015 at Kartal Koşuyolu Yüksek İhtisas Training and Research Hospital's Endoscopy Unit were reviewed retrospectively., Results: Within the duration of the study, 5.586 patients underwent colonoscopies at our hospital; 7 (0.12%) of these patients contracted iatrogenic colonic perforation. Three (42.8%) of these patients were male, four (57.2%) were female, and their mean age was 69 years (46 to 84). Six (85.7%) patients were diagnosed intraoperationally, while one (14.3%) patient was diagnosed 12 hours after the procedure. The perforation area was the sigmoid colon in six patients and the ascending colon in one patient; all patients underwent surgery. Four patients were discharged with no complications. One of the remaining three patients had enterocutaneous fistula, one had acute renal failure, and one died of sepsis., Conclusion: The progress of perforation due to colonoscopy varies according to the underlying diseases, the mechanism of perforation formation, the treatment modality used, and the experience of the physicians treating the patient. Special attention should be paid to senior and comorbid patients receiving therapeutic procedures during colonoscopy., Competing Interests: Conflict of Interest: No conflict of interest was declared by the authors.

Background: This study presents the relationship between mortality and spontaneous rectus sheath hematoma (RSH) in inpatients receiving anticoagulant and antiaggregant treatment for cardiac pathology at cardiology and cardiovascular surgery clinics., Methods: Within the scope of our study, the cases of 27 patients who were diagnosed with spontaneous RSH between January 2010 and December 2015 at Kartal Kosuyolu High Speciality Training and Research Hospital were retrospectively evaluated., Results: Of the 27 patients, 19 (70.4%) were female and 8 (29.6%) were male. The mean age was 63±12 (32-84) years. All the patients had at least one comorbidity that necessitated follow-up. Fourteen patients received only anticoagulant treatment, 8 received only antiaggregant treatment, and the remaining 5 received both types of treatment. Physical examination of all patients revealed painful palpable masses in the lower quadrants of the abdomen. According to the results of computed tomography (CT) scans, which showed the size and localization of the masses, 7 of the cases were classified as Type I, 6 as Type II, and 14 as Type III. Although 23 of the cases received medical treatment, the remaining 4 patients received surgical treatment. Eight (29.6%) patients suffered mortality., Conclusion: RSH is rare, but its prevalence is increased among patients receiving anticoagulant and antiaggregant treatment for cardiac reasons. The mortality rate markedly increased among patients who contracted RSH during hospitalization for cardiac reasons, had comorbidities, and experienced additional complications due to extended hospitalization.

Objective: Cancers of the proximal colon are often diagnosed in advanced stages with iron deficiency anemia and nonspecific symptoms. Aspirin and clopidogrel are commonly used antiaggregant agents for various clinical conditions. The aim of this study was to investigate the effects of antiaggregant medication on the early diagnosis of proximal colon cancer., Methods: Cases of colon cancer patients who had received curative surgical procedures between January 1, 2013 and July 31, 2016 were retrospectively reviewed. The clinical and pathological results of patients who had used antiaggregant drugs were compared to those who had not., Results: During the studied period, 246 colorectal cancer patients underwent curative surgical procedures. Of the 67 patients with proximal colon cancer who were included in the study, 27 (40.3%) had taken antiaggregant medication. The mean age of the antiaggregant group was 67.1 years (range: 34-88 years), while it was 58.3 years (range: 34-83 years) for the non-antiaggregant group; the difference between the 2 groups was statistically significant (p=0.03). A pathological evaluation revealed that 74.1% of the antiaggregant group was in the early stages (Stage I/II: 7/13), while 42.5% of the non-antiaggregant group was in the early stages (Stage I/II: 2/15); the difference was statistically significant (p=0.011)., Conclusion: Antiaggregant medication has a positive effect on diagnosing proximal colon cancer at early stages. Patients using aspirin or clopidogrel should undergo a complete colonoscopic evaluation in the presence of gastrointestinal tract bleeding or newly developed anemia., Competing Interests: Conflict of Interest: None declared.

Introduction: There is little information available on the clinical aspects, results, treatment and management of cardiac catheterization-related retroperitoneal hematoma. Data on the subject are rather limited, and current publications are based on a limited number of retrospective cohort studies and case reports., Aim: To perform a retrospective analysis of the demographic, clinical, and in-hospital results of patients who developed retroperitoneal hematoma (RPH) after cardiac catheterization (CC)., Material and Methods: The cases of 124,064 patients who had CCs between January 2010 and October 2016 were retrospectively analyzed. Patients diagnosed with RPH were classified into three groups depending on the method of treatment: conservative (group 1), endovascular stenting (group 2), and surgery (group 3). The independent risk factors, based on RPH-related mortality, were determined by logistic regression analysis., Results: Of the 68 (0.054%) patients with RPH, 75% received conservative treatment, 13.2% underwent angiographic stent placement, and 11.7% had surgical treatment. Red blood cell packets (RBCPs) ( p = 0.043), duration of hospitalization ( p = 0.007), and mortality rates ( p = 0.006) were statistically significantly higher in group 3 in comparison to the other groups. Multivariate subgroup analysis was conducted to determine mortality rates, with post-procedural highest creatinine ≥ 2 mg/dl and RBCPs ≥ 10 established as independent risk factors., Conclusions: Hemodynamically stable patients with no active hemorrhaging are shown to have good results with conservative treatment. We believe that endovascular methods should be used initially for hemodynamically unstable patients, while surgical treatment should be employed in cases where endovascular methods fail or abdominal compartment syndrome develops., Competing Interests: The authors declare no conflict of interest.

Small intestinal stricture forming in the late phase following nonpenetrating abdominal trauma is rare cause of ileus. It has often been suggested that it is result of localized feeding deficiency on the intestinal wall related to minor trauma in the mesentery. Laparoscopy has been increasingly used for diagnosis and treatment. Diagnosis should be supported by pathological analyses in case of intestinal stenosis related to blunt abdominal traumas.

Introduction: Emergency abdominal surgery (EAS) in patients with long-term mechanical circulatory support and strong anticoagulation is very difficult., Aim: To present our experiences regarding the short- and long-term results of patients with a left ventricular assist device (LVAD) who underwent emergency abdominal surgery under general anesthesia at a large tertiary healthcare center., Material and Methods: The electronic medical records of 7 patients with LVAD who underwent EAS between January 1, 2010 and December 31, 2016 were retrospectively investigated in order to evaluate perioperative management and outcomes. The patients were divided into two groups based on the need for EAS procedures., Results: Seven (9.2%) of 76 patients with LVAD underwent EAS an average of 79.1 ±79.4 days after implantation. No statistically significant differences were found between the groups with and without EAS with regard to demographic characteristics, type of device, and rate of perioperative mortality ( p > 0.05). The indications for surgery, retroperitoneal hematoma in 2 patients and in 5 other patients; ileus, iatrogenic splenic injury associated with thoracentesis, splenic abscess, acute abdominal pain and rectal cancer surgery was a pelvic abscess in a patient who is connected to the stump. In all cases laparotomy was performed with median incision. The perioperative mortality rate was 28.6% ( n = 2). Two patients underwent orthotopic heart transplant during long-term follow-up., Conclusions: The EAS is not rare during LVAD treatment but is a rather complex procedure. General surgeons will be increasingly likely to encounter such patients as their numbers rise and their life expectancies are prolonged.

Aim of the Study: Examination of esophagojejunal (EJ) anastomosis with aqueous contrast swallow after total gastrectomy is still routinely conducted by many centres. The present study aimed to answer the question: Is it necessary to evaluate EJ anastomosis in terms of leakage by having every patient drink oral contrast agent before initiation of oral food intake after total gastrectomy (TG) performed due to gastric cancer?, Material and Methods: Clinical and radiological results of patients on whom total gastrectomy was performed due to gastric cancer between January 2013 and December 2016 were retrospectively reviewed. Diagnostic method used for patients in whom leak developed and therapeutic interventions were assessed. Evaluation results from aqueous contrast agent and clinical, laboratory, and tomographic findings were studied., Results: Sixty of the 69 patients who underwent total gastrectomy with a diagnosis of gastric adenocarcinoma swallowed aqueous contrast agent on postoperative day 7 ±2 days and were evaluated in terms of anastomotic leak. Leak developed in 14 patients (20.2 %), 10 of whom ingested contrast agent. Leak was identified in 6 of those patients; however, diagnosis was made with multislice computed tomography (CT) in four patients (40%). The sensitivity of the examination with aqueous contrast agent was 60%., Conclusions: Evaluating anastomotic leak with aqueous contrast agent after TG has low sensitivity, and it would be wise to resort to this procedure in cases with clinical suspicion, rather than routinely performing it in every patient., Competing Interests: The authors declare no conflict of interest.

Aim: To provide an overview of the medical literature on cutaneous fistulization in patients with hydatid disease (HD)., Methods: According to PRISMA guidelines a literature search was made in PubMed, Medline, Google Scholar, and Google databases were searched using keywords to identify articles related to cutaneous fistulization of the HD. Keywords used were hydatid disease, hydatid cyst, cutaneous fistulization, cysto-cutaneous fistulization, external rupture, and external fistulization. The literature search included case reports, review articles, original articles, and meeting presentations published until July 2016 without restrictions on language, journal, or country. Articles and abstracts containing adequate information, such as age, sex, cyst size, cyst location, clinical presentation, fistula opening location, and management, were included in the study, whereas articles with insufficient clinical and demographic data were excluded. We also present a new case of cysto-cutaneous fistulization of a liver hydatid cyst., Results: The literature review included 38 articles (32 full text, 2 abstracts, and 4 unavailable) on cutaneous fistulization in patients with HD. Among the 38 articles included in the study, 22 were written in English, 13 in French, 1 in German, 1 in Italian, and 1 in Spanish. Forty patients (21 males and 19 females; mean age ± standard deviation, 54.0 ± 21.5 years; range, 7-93 years) were involved in the study. Twenty-four patients had cysto-cutaneous fistulization (Echinococcus granulosus); 10 had cutaneous fistulization (E multilocularis), 3 had cysto-cutaneo-bronchio-biliary fistulization, 2 had cysto-cutaneo-bronchial fistulization; and 1 had cutaneo-bronchial fistulization (E multilocularis). Twenty-nine patients were diagnosed with E granulosis and 11 had E multilocularis detected by clinical, radiological, and/or histopathological examinations., Conclusion: Cutaneous fistulization is a rare complication of HD. Complicated HD should be considered in the differential diagnosis of cases presenting with cutaneous fistulization, particularly in regions where HD is endemic., Competing Interests: The authors have no have no funding and conflicts of interest to disclose.
