Is the increased incidence of pathologically proven acute appendicitis more likely seen in elderly patients? A retrospective cohort study.

AIM: Although appendicitis is a disease of the young, it has been speculated that its incidence has increased among the elderly people. In this study, it was aimed to evaluate annual changes of appendicitis seen in older patients (≥60 years) throughout a 10-year period. METHODS: All adult patients who were surgically treated for acute appendicitis were retrospectively analyzed with respect to pathological analysis, gender, age and proportion of the patients aged 60 or over in an annual base. Variability in the mean age and proportion of the older patients aged 60 or over throughout the study years were regarded as the main outcomes. RESULTS: There were 3296 patients with a mean age of 30.42 ± 12 years. Distribution of gender was similar (p = 0.636). There was a significant positive correlation in the mean age of the patients throughout the study years (p = 0.043). Stratification by the age of 60 yielded a significant increase in percent of the older patients, from 0.93% at 2007 to 4.28% at 2016 (p = 0.019). CONCLUSIONS: The mean age of the patients with acute appendicitis is going to increase. Therefore, it is expected that all surgeons are more likely to be confronted with elderly patients with appendicitis in the near-future.

Analysis of reporting quality for oral presentations of observational studies at 19th National Surgical Congress: Proposal for a national evaluation system.

OBJECTIVE: To compare the quality of oral presentations presented at the 19th National Surgical Congress with a national evaluation system with respect to the applicability of systems, and consistency between systems and reviewers. MATERIAL AND METHODS: Fifty randomly selected observational studies, which were blinded for author and institute information, were evaluated by using the Strengthening the Reporting of Observational Studies (STROBE), Timmer Score, and National Evaluation System by two reviewers. Abstract scores, evaluation periods, and compatibility between reviewers were compared for each evaluation system. Abstract scores by three different evaluation systems were regarded as the main outcome. Wilcoxon matched-pairs signed rank and Friedman tests for comparison of scores and times, kappa analysis for compatibility between reviewers, and Spearman correlation for analysis of reviewers based on pairs of evaluation systems were used. RESULTS: There was no significant difference between abstract scores for each system (p>0.05). A significant difference for evaluation period of reviewers was detected for each system (p<0.05). Compatibility between reviewers was the highest for the Timmer Score (medium, κ=0.523), and the compatibility for STROBE and National Evaluation System was regarded as acceptable (κ=0.394 and κ=0.354, respectively). Assessment of reviewers for pairs of evaluation systems revealed that scores increased in the same direction with each other significantly (p<0.05). CONCLUSION: The National Evaluation System is an appropriate method for evaluation of conference abstracts due to the consistent results between the referees similarly with the current international evaluation systems and ease of applicability with regard to evaluation period.

Intraoperative diagnosis of cecal diverticulitis during surgery for acute appendicitis: Case series.

OBJECTIVE: Cecal diverticulum is a rare entity, and can cause acute abdomen by the way of diverticulitis and perforation of diverticulitis. In this study, we aimed to perform an analysis of patients that have cecal diverticulitis, and presented with acute abdomen. MATERIAL AND METHODS: Patients who were admitted to emergency clinic between 2009-2012 and had acute abdomen due to cecal diverticulitis were included into study retrospectively. RESULTS: Six patients were included in the study with a mean age of 34 years (range 24-43). Four patients were male and two were female (male/female: 2). All six patients presented with abdominal pain, additional symptoms were nausea in five patients, and vomiting in one patient. The mean white blood cell count was 11.900/mm(3) (5850-17.400/mm(3)), while the remaining laboratory results were normal. There were no specific findings on abdominal X-ray or ultrasonography. The surgical exploration revealed an inflamed cecal diverticulitis and normal appendix in all patients. Five patients underwent appendectomy and diverticulectomy. Right hemicolectomy was performed in one patient due to suspicion of malignancy. The early postoperative period was uneventful in all patients. The mean length of hospital stay was 4.5 days with a range of 2-6 days. Histopathological examination showed acute perforated diverticulitis with underlying true diverticulum in three patients, and true diverticulum with acute diverticulitis in the remaining three patients. CONCLUSION: Pre-operative diagnosis of cecal diverticulitis is challenging due to symptoms and signs that resemble acute appendicitis. Diverticulectomy and incidental appendectomy is the treatment of choice in uncomplicated cases.

Interposition of the hernia sac as a protective layer in repair of giant incisional hernia with polypropylene mesh.

BACKGROUND AND PURPOSE: Repair of giant incisional hernia is still associated with high postoperative morbidity and recurrence rates. We evaluated the effectiveness of placing the hernia sac between the viscera and the polypropylene mesh in the repair. METHODS: The subjects of this study were patients with an incisional hernia at least 15 cm in diameter, diagnosed between June 2004 and October 2010 and treated with on-lay polypropylene mesh at least 25 cm in length. We operated using a simplified method of placing the hernia sac between the viscera and the mesh, and fixing the mesh with interrupted trans-fascial U sutures. We evaluated the patient demographics and postoperative complications retrospectively. RESULTS: A total of 25 patients (mean age 57.1 ± 10 years) were included. The mean length of hospital stay was 1.8 ± 1.2 days. Seroma developed in four patients (16 %), but only two with cystic seroma required excision of the cyst wall with preservation of the mesh. Twenty-two patients (88 %) were followed up for a mean period of 42.6 ± 23 months. There was no incidence of chronic pain, hospitalization for intestinal obstruction, or enterocutaneous fistulization. There was only one recurrence (4.55 %). CONCLUSION: The hernia sac can be interposed in all patients undergoing giant incisional hernia repair if direct contact between the polypropylene mesh and intestine is unavoidable.

Evaluation of reporting quality of the 2010 and 2012 National Surgical Congress oral presentations by CONSORT, STROBE and Timmer criteria.

OBJECTIVE: This study aimed to evaluate the abstracts of oral presentations that were accepted to the National Surgical Congress by CONSORT, STROBE and Timmer criteria and to recommend development of a national abstract assessment system. MATERIAL AND METHODS: Presentation scores were calculated for oral presentations that have been accepted to the 2010 and 2012 National Surgical Congresses and have been included in the digital congress abstract booklets by two independent reviewers who were blinded to information regarding both the author and the institution. The CONSORT and Timmer criteria were used for randomized controlled trials, and for observational studies the STROBE and Timmer criteria were used. The presentation score that was obtained by three different evaluation systems was accepted as the main variable. The score changes according to the two congresses, the influence of the reviewers on the presentation scores, and compatibility between the two reviewers were evaluated. Comparisons regarding study types and total presentation number were made by using the chi-square test, the compatibility between the total score of the presentations were made by the Mann-Whitney U test and the compatibility between the reviewers were evaluated by the Wilcoxon signed ranks test. RESULTS: There was no difference between the two Congresses in terms of study type distribution and total number of accepted presentations (p=0.844). The total scores of randomized controlled trials and observational studies from the 2010 and 2012 National Surgical Congresses that were evaluated by two independent reviewers with different assessment tools did not show any significant difference (p>0.05). A significant difference was observed between the reviewers in their evaluation by CONSORT, STROBE and Timmer criteria (p<0.05). CONCLUSION: Implementation of standard criteria for the evaluation of abstracts that are sent to congresses is important in terms of presentation reporting quality. The existing criteria should be revised according to national factors, in order to reduce the significant differences between reviewers. It is believed that discussions on a new evaluation system will be beneficial in terms of the development of a national assessment system.

The management of penetrating abdominal stab wounds with organ or omentum evisceration: The results of a clinical trial.

OBJECTIVE: The therapeutic approach to abdominal penetrating stab injuries has changed over the years from routine laparotomy to non-operative treatment. In case of organ or omental evisceration, although the laparotomy need is greater, non-operative treatment may be applied in selected cases. The aim of our study was to assess the follow-up and treatment outcomes of patients with organ or omental evisceration due to penetrating abdominal injuries. MATERIAL AND METHODS: Patients with organ or omental evisceration due to penetrating abdominal stab injuries were prospectively evaluated between April 2009 and July 2012. Emergent laparotomy was performed in cases that were hemodynamically unstable or had signs of organ evisceration or peritonitis, while other patients were managed conservatively. Patients' follow-up and treatment outcomes were assessed. RESULTS: A total of 18 patients with organ or omental evisceration were assessed. Six (33.3%) patients underwent emergent laparotomy, and 12 (66.7%) patients underwent conservative follow-up. Three patients in the emergent laparotomy group had signs of organ evisceration, and 3 had signs of peritonitis; five of these 6 patients underwent therapeutic laparotomy and 1 negative laparotomy. In the non-operative follow-up group, therapeutic laparotomy was carried out in a total of 7 patients, 4 being early and 3 late, due to development of peritonitis, whereas 5 (27.8%) patients were managed non-operatively. CONCLUSION: Although organ or omental eviscerations due to penetrating abdominal stab injuries have a high rate of therapeutic laparotomy, selective conservative therapy is a safe method in selected cases.

Standard laparoscopic cholecystectomy for malposition of the gallbladder caused by right-sided ligamentum teres.

Atypical localization of the gallbladder associated with right-sided ligamentum teres is a rare anomaly of the biliary system. Although the conventional nomenclature as being a left-sided gallbladder is usually used, this definition may be incomprehensive because of lacking the anatomical detail. This report describes atypical localization of the gallbladder associated with right-sided ligamentum teres and abnormal intrahepatic portal venous branching, surgically removed laparoscopically.

Enhanced Recovery After Surgery Promotes Recovery in Sleeve Gastrectomy: A Randomized Controlled Trial.

Introduction: The most popular approach for treating obesity is laparoscopic sleeve gastrectomy (LSG). The enhanced recovery after surgery (ERAS) protocol aims to reduce the patient's surgical stress response, optimize their physiological function, and facilitate recovery. The purpose of this study was to investigate the efficacy and safety of the ERAS protocol in patients who have undergone LSG. Methods: Between January 2020 and March 2021, a single-center randomized controlled study with patients undergoing LSG was planned. Patient demographics, duration of surgery and anesthetic induction, postoperative nausea-vomiting (PONV) and pain scores, length of hospital stay, and emergency room readmissions within the first 30 days were also documented. Patients were divided into two groups: those who followed the ERAS protocol and those who did not. The senior surgeon was blinded for the preoperative and postoperative period, whereas the other surgeon was not. The groups were compared in terms of length of hospital stay, duration of surgery, visual analog scale (VAS) scores, PONV effect scores, and emergency service admissions within the first 30 days after surgery. Results: A total of 96 patients were included in this study. Of these, 49 were in the ERAS protocol group and 47 were in the traditional treatment group. The mean age of the patients in the ERAS and traditional treatment groups were 37.47 ± 10.11 years and 35.77 ± 9.62 years, respectively. While the ERAS group patients were hospitalized for a mean of 30.46 ± 11.26 hours, the traditional group patients were hospitalized for 52.02 ± 6.63 hours (P: .001). There was no difference between the groups in terms of the first 30-day readmission to the emergency department (P: .498). Both VAS and PONV effect scores at the 2nd and 12th hours of the ERAS group patients were lower (P: .001, .002, .001, .001, respectively). Conclusions: When compared with the conventional method, the ERAS protocol reduced patient hospitalization time, decreased postoperative nausea, vomiting, and pain scores, and did not vary in postoperative emergency department readmissions. In patients receiving LSG, the ERAS protocol can be employed safely and successfully. Clinical Trial Registration number: NCT04442568.

What Value of Sixth Month Excess Weight Loss (Postsleeve Gastrectomy) Is Necessary for Better Sleep Quality?

BACKGROUND: Obesity, caused by caloric intake over output, is a global health problem. The relationship between sleep and obesity is discussed in the literature. Little is known about the compliance of sleep quality and patients' weight loss. This study aimed to review how sleep quality is affected by bariatric surgery, assess whether compliance with sleep quality can be predicted after bariatric surgery, and establish its correlation with excess weight loss. METHODS: A cross-sectional study was conducted for patients undergoing bariatric surgery (laparoscopic sleeve gastrectomy). Sleep quality was assessed with the Pittsburgh sleep quality index (PSQI) scale preoperatively and in the sixth postoperative month. A PSQI global score above 5 indicated poor sleep quality. Participants were divided into 2 groups: good and poor sleep quality. Receiver operating characteristics and logistic regression analysis were also performed to predict sleep quality. RESULTS: The questionnaire was completed by 100 subjects. All PSQI components, except the sixth (sleep medication) component, improved in patients at the sixth postoperative month versus baseline values. In the receiver operating characteristic analysis to test the availability of excess weight loss (EWL%) cutoff values relative to predict successful sleepers, 65.1 of the sixth month EWL% was found for the diagnosis of successful sleeper patients with 72.6% sensitivity and 63% specificity (area under the curve: 0.706, P =0.002, 95% CI, 0.586 to 0.825). CONCLUSIONS: For patients undergoing weight loss surgery, while assessing the sixth postoperative month, the EWL% value over 65.1 was recommended for better sleep quality.

The role of leukocytes in predicting whether laparotomy is required in patients with penetrating abdominal stab wound.

BACKGROUND: This study aimed to determine the importance of leukocytes, leukocyte subgroups, platelets, neutrophil-to-lymphocyte ratio, and platelet-to-lymphocyte ratio in deciding whether laparotomy is required during observation in patients with penetrating abdominal stab wounds who were followed up because there was no indication for an emergency laparotomy. METHODS: Patients who did not indicate an emergency laparotomy were monitored. After 48 hours from initial hospitalization, patients who did not require laparotomy were discharged nonoperatively. The total leukocytes, leukocyte subsets, platelets, neutrophil-to-lymphocyte ratio, and platelet-to-lymphocyte ratio of patients who underwent laparotomy during the follow-up compared with those who were discharged nonoperatively. The sensitivity and specificity of these laboratory values in predicting the necessity of laparotomy were calculated. RESULTS: In the operated group (n = 71), leukocytes, neutrophils, monocytes, neutrophil-to-lymphocyte ratio, and platelet-to-lymphocyte ratio examined during observation were significantly higher (P < .001). Eosinophils and lymphocytes were significantly lower (P < .001) than in nonoperated (n = 476). Based on the deviation in the reference ranges of leukocyte and its subgroups, we report the sensitivity and specificity for predicting the necessity of laparotomy as 86% and 72% for leukocyte, 88% and 75% for neutrophil, 92% and 83% for neutrophil-to-lymphocyte ratio, and 72% and 77% for platelet-to-lymphocyte ratio, respectively. In receiver operating characteristic curve analysis, the cut-off value was found to be 4 for neutrophil-to-lymphocyte ratio and 125 for platelet-to-lymphocyte ratio (area under the curve/receiver operating characteristic curve of 0.929 and 0.808, respectively). CONCLUSION: Leukocyte, leukocyte subgroups, neutrophil-to-lymphocyte ratio, and platelet-to-lymphocyte ratio may be useful to determine if a laparotomy is necessary in patients in whom the necessity of laparotomy is undetermined owing to unclear examination findings.

Gastric outlet obstruction caused by Riedel's lobe of the liver: a diagnostic and therapeutic challenge for surgeons.

Gastric outlet obstruction is commonly caused by gastric ulcers, pyloric stenosis, foreign bodies, and compression of the duodenum by pancreatic cancer and other intra-abdominal masses. There is no report on Riedel's lobe of the liver as a cause of this condition. This is the first report to describe Riedel's lobe of the liver as a cause of gastric outlet obstruction. An 81-year-old woman who complained of severe nausea and abdominal discomfort was admitted to our clinic. The physical examination revealed a mass in the right upper quadrant of the abdomen. An exploratory laparotomy showed an approximately 10x6-cm tongue-like mass arising from the left lobe of the liver, extending to the umbilicus and compressing the prepyloric area of the stomach. The nature and location of the mass were compatible with Riedel's lobe. A cholecystectomy was performed and the compressing mass was fixed to the abdominal wall with a simple suture. The patient did well postoperatively and was discharged from the hospital. We also reviewed the English-language literature to provide an update on this subject.

Relationship between monocyte-to-high-density lipoprotein cholesterol ratio and excess weight loss in laparoscopic sleeve gastrectomy.

Aim: The present study evaluates the relationship between the monocyte-to-high-density lipoprotein cholesterol ratio (MHR) and the percentage of excess weight loss (%EWL) in patients undergoing laparoscopic sleeve gastrectomy. Method: This prospective cohort study evaluated 125 patients who underwent laparoscopic sleeve gastrectomy. The MHR before and at 6 months after surgery were compared in patients with <50 and ≥50 %EWL. Results: The MHR was lower in patients with a %EWL of <50 than in patients with a %EWL of ≥50 (p = 0.019). The decrease in the MHR at postoperative 6 months was more remarkable in patients with a %EWL of ≥50 (p < 0.001). Conclusion: The present study suggests that MHR decreased more remarkably at postoperative 6 months in patients with high %EWL, predicting a decrease in cardiovascular risk.

Lay abstract The primary focus of laparoscopic sleeve gastrectomy is to achieve sufficient weight loss to reduce cardiovascular events while minimizing surgical morbidity. The present study found a significant relationship between the percentage of excess weight loss and monocyte-to-high-density lipoprotein cholesterol ratio (MHR), the decrease in MHR being more remarkable with increasing excess weight loss and mostly attributable to the monocyte component. MHR can be used as a marker of atherosclerosis to monitor patients if they have achieved a reduction in cardiovascular risks. Monocyte count can be used as a simple substitute in conditions where MHR is not readily available.

Presurgical Predictive Factors of Excess Weight Loss After Laparoscopic Sleeve Gastrectomy.

PURPOSE: Conditions associated with surgical technique and postoperative lifestyle changes, as well as the characteristics of patients, may affect weight loss following laparoscopic sleeve gastrectomy. In this study, the effects of age, gender, BMI, and excess weight at the time of surgery on weight loss during follow-up were examined. MATERIALS AND METHODS: Demographic data (age, gender), preoperative BMI, and weight values of the patients were recorded. TWL% and EWL% values of patients were recorded during follow-up at 1st, 3rd, 6th, 9th, 12th, and 18th months. Patients were grouped according to age (AGE1 < 30, AGE2 30-50, AGE3 ≥ 50 years), BMI at the time of surgery (BMI1 ≤ 50, BMI2 > 50 kg/m2), and EW at the time of surgery (EW1 ≤ 60, EW2 > 60 kg). EWL% values obtained in the follow-up visits were compared among the gender, age, BMI, and EW groups. RESULTS: A total of 456 patients (371 females, 85 males) were operated. Mean EWL% was lower in AGE3 group (p < 0.001). Patients in AGE1 group had the highest mean EWL%, while those in BMI2 and EW2 groups had lower mean EWL% values throughout the follow-up period (p < 0.001). Regression analysis showed that age and BMI were associated with EWL% at all follow-up visits (p < 0.05). CONCLUSION: Patients with less than 60 kg of excess weight, those with BMI ≤ 50 kg/m2 and younger patients may lose weight more effectively following LSG.

Recovery from hemorrhoids and anal fissure without surgery.

BACKGROUND/AIMS: An anal fissure (AF) is a linear tear in the distal anal canal and is one of the most common causes of anal pain. Hemorrhoidal disease (HD) is a symptomatic growth and distal displacement of normal anal cushions. Numerous studies have addressed the contributing factors of these conditions, yet the results remain controversial. In this study, we hypothesize that increasing patients' awareness of hidden risk factors could reduce the rate of HD and AF. MATERIALS AND METHODS: A questionnaire-based controlled study was planned. After power analysis, patients with HD (n=60) and AF (n=60) were enrolled consecutively into the study group and compared with the control group (n=60) of healthy individuals. The survey was designed to assess the participants' toilet and dietary habits and anxiety risk. Odds ratios were calculated and a binary logistic regression model was constructed to identify associated factors. RESULTS: Hard stools, spending more than 5 minutes in the toilet, frequent straining during defecation, and increased spice intake were more frequent in the patients with HD; and hard fecal consistency, time elapsed in toilet greater than 5 min, straining during defecation, and high anxiety risk were more frequent in the patients with AF as compared to the control group (p<0.05). CONCLUSION: Possible associations were identified between habitual factors or conditions (i.e., fecal consistency, the time elapsed in the toilet, straining during defecation) and anxiety and benign anorectal diseases (i.e., HD and AF). Patients should be advised about these hidden threats.

Risk factors for complications after endoscopic retrograde cholangiopancreatography A referral Center experience.

AIM: Endoscopic retrograde cholangiopancreatography (ERCP) is an important diagnostic and therapeutic tool in patients with hepato-pancreatobiliary diseases. In the present study, we sought to determine predictors of post-ERCP complications at our institution. METHODS: A retrospective analysis of patients who underwent ERCP in between January 2010 and November 2011 was done. Demographics, indications, ERCP findings, success rate, complications and the need of repeat procedure were evaluated with special emphasis on the difficulty in cannulation procedure, the primary etiology of the disease (benign/malign) and age. Chi-square analysis was applied for statistical analysis. The differences were considered statistically significant, if the p value was less than 0.05. RESULTS: A total of 112 ERCP was performed in 81 patients. Thirty-eight were male (46.9 %) and 43 were female (53.1%). Mean age was 61.3 (range 17-88), and 31 patients was seventy years and older (38.3 %). Complications were detected in 28 patients (34.6 %). Nine cases with difficult or unsuccessful cannulation (69.2 %) had complications (p=0.001). Patients with benign diseases showed less complications (21/70), in comparison with those with malignancies (7/11) (30 % vs. 63.6 %, respectively; p<0.05). Complication rate in patients 70 years and older was 32.2 % (n=10) compared to 35.3 % in patients younger than 70 (n= 18) (p<0.05). CONCLUSION: Risk factors such as difficult or incomplete cannulation and malignancy are considered as possible predisposing factors for complications. Age is an independent factor. KEY WORDS: Endoscopic cholangiopancreatography, Risk factors.

A clinical and surgical challenge: Retrorectal tumors.

AIMS: Retrorectal tumors are rare, mostly benign tumors and named due to their localization. Diagnoses of these tumors are usually delayed because of nonspecific complaints and symptoms. Magnetic resonance imaging has beneficial uses both for diagnosis and treatment. In this study, we reviewed a case series of retrorectal tumors. SUBJECTS AND METHODS: The patients who were diagnosed with retrorectal tumors between 2008 and 2015 were analyzed. This investigation was conducted at a Tertiary Education and Research Hospital. Sixteen patients were included in this study. Patients' demographic data, imaging workups, surgical operation reports, pathologic examination results, postoperative complications, and follow-up results were examined. Descriptive statistics, median, and standard deviation for continuous variables were used. The primary outcomes measured were diagnostic conflict, knowledge, and preference for surgery. STATISTICAL ANALYSIS USED: Definitive statistical methods (mean, standard deviation, median, frequency, and percentage) were used to evaluate the study data. RESULTS: One patient refused operation and one was in preoperative preparation period. Fourteen of sixteen patients were operated. Two (14.3%) of operated patients have malignant histopathological result (one gastrointestinal stromal tumor, one ganglioneuroblastoma). Rest of the operated patients' histopathological reports was as follows: Four schwannomas, three epidermoid cysts, two tailgut cyst, one dermoid cyst, one teratoma, and one angiomyolipoma. Eight patients were operated by posterior incision, five patients with transabdominal approach, and one patient with combined approach. CONCLUSIONS: Retrorectal tumors are rare cases, and treatment of retrorectal tumors is surgery and should be operated in referenced hospitals to avoid diagnostic and therapeutic problems.

Does it matter if it is appendix mucocele instead of appendicitis? Case series and brief review of literature.

AIMS: Appendiceal mucocele (AM) is a rare pathology, and its reported incidence is 0.3% in all appendectomy specimens. Here, we report a case series of AM and make a brief review of literature. SUBJECTS AND METHODS: We conducted a retrospective review of a prospectively collected data of patients who diagnosed as AM by histopathological evaluation between January 2009 and June 2015 were demographic data including age and gender, intraoperative findings, and histopathological reports were recorded. All cases were followed-up by routine examination and telephone interview. STATISTICAL ANALYSIS USED: Definitive statistical methods (mean, standard deviation, median, frequency, and percentage) were used to evaluate the study data. RESULTS: Twelve patients were examined in the study with diagnose of AM. The mean age was 51.8 ± 18.6 years (26-83). Female-to-male ratio was 1.4 (7/5). Indications for surgery were acute abdomen in 8 (72.7%) patients with presumptive diagnosis of acute appendicitis and were AM in four patients diagnosed by imaging. Histopathological evaluation revealed mucinous cystadenoma in eight patients, simple retention cysts in three, and borderline mucinous tumor (pseudomyxoma peritonei) in one. The neuroendocrine tumor was obtained on the remaining portion of the appendix in one of the simple retention cysts patients. None of the patients died because of the AM with an average follow-up of 43 months (range: 7-74). CONCLUSIONS: Surgical resection is the first choice therapy for AM. Precise treatment modality can remain unclear in some patients because of insufficient preoperative diagnosis. It is nonmalign AM mostly however having mucocele matters because of the significant association with synchronous tumors.

An incidental giant preperitoneal fibrolipoma diagnosed during laparoscopic cholecystectomy.

Preperitoneal lipomas are rare in clinical practice. Here we report an unexpected diagnosis of a giant preperitoneal fibrolipoma detected intraoperatively during laparoscopic cholecystectomy in a 56-year-old woman. The mass was excised and a histopathological examination confirmed fibrolipoma. No recurrence was found on follow-up. In the literature, there have been many cases with unexpected diagnoses during laparoscopy. Here, we present an incidental giant preperitoneal fibrolipoma, which was overlooked by ultrasound and physical examination, but was detected during laparoscopic cholecystectomy.

Evaluating factors affecting survival in colon and rectum cancer: A prospective cohort study with 161 patients.

CONTEXT: Colorectal cancers are frequent among cancers of gastrointestinal system. Whether there are any differences between survival in rectum and colon cancer patients is controversial. AIMS: In this study, we aimed to compare survival in surgically treated rectum and colon cancers and determine the factors affecting survival. SUBJECTS AND METHODS: The patients with colon and rectum cancer operated between 2009 and 2013 were examined retrospectively using prospective database. Patients were categorized as colon and rectum according to the tumor's location. Survival was identified as the primary outcome. Kaplan-Meier survival analysis and log-rank tests in survival assessment were used. RESULTS: One hundred and sixty-one patients with a mean age of 62.8 ± 12.7 years were included in the study. Male/female ratio was 1.6. Colon and rectum patients were counted as 92 (%57.1) and 69 (%42.9), respectively. Both groups were similar in demographic data (P > 0.05). It was observed that in 46 months (mean) of follow-up, 39.7% (n: 64) died, and 60.3% (n: 97) survived. Median survival time was 79 months, and 5-year cumulative survival rate was 60.8%. Five-year cumulative survival rates in stages for 1, 2, 3 and 4 were 88.2%, 64.7%, 48.5%, and 37.0%, respectively. It was noted that median survival time for colon cancer was 78 months and for rectum cancer was 79 months. Five-year cumulative survival rates for colon and rectum cancers were calculated as 56.7% and 63.4%, respectively. There were no significant differences in colon and rectum cancers in the means of survival rate (P: 0.459). CONCLUSIONS: While location of colorectal cancers shows no significant effect on survival, treatment in the early stages increases survival rate.

Efficacy of local sclerosing agents on hemostasis of hepatic bleeding.

BACKGROUND/AIMS: Hepatic bleeding following abdominal trauma is a serious problem. The implementation of various materials and techniques have been attempted to prevent bleeding but a standard method is indefinite. METHODOLOGY: Hepatic resection model was performed on rats. The efficacy of hemostasis with Polidocanol and Tetradecyl Sulfate has been evaluated through the comparison of perioperative bleeding amount and preoperative and postoperative hematocrit levels in the 24th hour. Also, histopathologic changes on parenchyma have been compared at a microscopic level. RESULTS: Preoperative and postoperative hematocrit differences were 5.50 +/- 0.59 in Polidocanol group and 10 +/- 1.30 in Tetradecyl Sulfate group (MW: 2, p < 0.001). Perioperative bleeding amounts were: 1.50 +/- 0.20 mL in the Polidocanol group, 3.50 +/- 0.15 mL in the Tetradecyl Sulfate group and 7.50 +/- 0.41 mL in the Control Group. Upon comparison of perioperative bleeding amounts: the Control Group values were very high in comparison to the Polidocanol group (p < 0.001) and the Tetradecyl Sulfate group values were higher than those of the Polidocanol group (p < 0.05). CONCLUSIONS: Local sclerosing agents, especially Polidocanol, appear to be an effective alternative method in hemostasis of hepatic bleeding.
