[An Important Problem in AdV-36 Seropositive Obesity Patients: Leptin Resistance]

Adenoviruses are naked viruses with an icosahedral nucleocapsid containing a 36 kb linear double-stranded DNA genome that encodes 30-40 proteins. The word "obesity" in Latin means "because of feeding". Obesity is an energy metabolism pathology that paves the way for physical and psychological problems with excessive fat accumulation that can impair health. Body mass index (BMI), unaffected by gender and age, is the most useful indicator of overweight and obesity at the population level. The concept of infectobesity was first introduced in 1978 after the data showed that viruses might also play a role in obesity cases. In the same year, adenovirus 36 (AdV-36) was isolated from the stool of a six-year-old girl with diabetes who was admitted to the hospital with the complaint of enteritis. One of the adipokines important for obesity is leptin. Leptin regulates food intake and energy metabolism by having a "negative feedback" effect on the hypothalamus. Leptin acts as a sensor that acutely regulates energy metabolism by creating hunger and satiety signals and it also regulates the amount of body fat and the required weight of the person by adjusting its concentration in the plasma according to the nutritional status. Changes in body weight and metabolic status are often associated with acute or chronic inflammatory processes. Human cells infected by AdV-36 showed greater differentiation and higher lipid accumulation than uninfected control cells, which increases the prevalence of obesity. There are two fractions of serum leptin, protein-bound and free form. The balance between these two fractions depends on serum leptin and soluble leptin receptor (sLR) plasma concentration, which is adversely affected by BMI. AdV-36 infection reduces norepinephrine and leptin levels. These two effects contribute to obesity by increasing appetite and food intake. In this study, it was aimed to determine the presence of immunoglobulin G against AdV-36 in the blood serum of obesity patients (BMI≥ 30) and healthy weight individuals (18.5≤ BMI≤ 25), and also aimed to determine and compare the leptin and soluble leptin receptor levels of these individuals. In this study, 10 ml of blood was collected on an empty stomach from obese individuals (n= 101; BMI≥ 30) and healthy individuals (n= 96; 18.5≤ BMI≤ 25) between the ages of 18-55. All participants consisted of who were not taking any medication and were not immunosuppressed. Blood samples separated into their serum were analyzed for AdV-36 IgG, leptin, and soluble leptin receptor levels. Mean, standard deviation, and percentage values were calculated by descriptive statistical analysis. The data with normal distribution were evaluated with the paired and independent sample t-test and data with abnormal distribution were evaluated with the paired and independent sample Mann-Whitney U test. Findings with a p-value less than 0.05 were considered statistically significant. In conclusion, leptin levels in obese individuals who were not infected with Adv-36 were found to be low, in line with the principle that "insufficient leptin synthesis has a role in the pathophysiology of obesity". When AdV-36 infection is added to the obesity picture, it may be due to the fact that it increases leptin synthesis in patients and the level of soluble leptin receptors increases in response to the increased leptin level, that AdV-36 suppresses the binding of the leptin molecule to its receptor, which leads to leptin resistance.

The role of selective venous sampling in patients with non-localized primary hyperparathyroidism

Objectives

The aim of this observational clinical study was to evaluate the success of angiographic selective venous sampling (ASVS) in locating parathyroid adenoma in patients with primary hyperparathyroidism (PHPT), in whom the other imaging modalities have failed, and and to evaluate its possible contribution to the applicability of minimal invasive surgery.

Material and Methods

Fifty-five patients who were admitted to our hospital's General Surgery department between January 2012 and January 2015 for PHPT in whom ultrasound and sestamibi scintigraphy have failed to localize the diseased gland were included to the study. Patients were divided into two groups: those who underwent ASVS and those who did not. The outcomes of patients were reviewed retrospectively.

Results

Among 55 patients, 20 underwent ASVS. ASVS successfully lateralized the diseased gland in 17 (85%) patients, and minimally invasive parathyroidectomy could be performed in 14 (70%) patients. The cut-off value of parathormon gradient was considered 10% for lateralization and the accuracy of ASVS in lateralization was 94.1%. In 11 (59%) patients, the superior-inferior discrimination could be achieved in addition to lateralization.

Conclusion

ASVS has a high sensitivity in locating the diseased gland in patients with PHPT in whom ultrasound and sestamibi scan have failed, and thereby, rendering the performance of minimally invasive surgery possible. Further studies may reveal the role of ASVS in providing useful information about not only lateralization but also the superior-inferior discrimination.

Colonic Stent Use in Patients With Malignant Flexure Tumors Presenting With Obstruction

Background and Objective:

Colonic stenting in left-sided tumor is being commonly used. However, placing a stent in the flexure tumors is rare because it is technically more difficult. In this study, we aimed to retrospectively screen patients with flexure tumors admitted to our clinic who were treated using a colonic stent and discuss our findings.

Methods:

Patients admitted to the emergency department for obstructive colonic tumors between 2012 and 2017 were retrospectively evaluated, and 21 patients treated using stents were included in the study. The expandable metal stent (Wallflex®, Boston Scientific, Marlborough, MA, USA) was placed at the obstruction through the lead wire.

Results:

The mean age of the patients was 62 years, and the ratio of females to males was 3:18. Splenic flexure tumors were detected in 18 patients and hepatic flexure tumors in 3 patients. Seven of the patients were stented for palliative purposes. Fourteen of the cases underwent surgery. Three of them underwent laparoscopic surgery and eleven underwent open surgery.

Conclusions:

Preoperative stenting in colonic flexura tumors is associated with faster healing, less postoperative complications, lower rates of colostomy, and higher rates of minimally invasive surgery, and can be safely used at experienced centers.

Laparoscopic resection and intracorporeal anastomosis of perforated small bowel caused by fish bone ingestion

Presently described is case of a 52-year-old man who was admitted to the emergency department with 3-day history of epigastric pain. Abdominal examination revealed diffuse tenderness and muscle guarding. Plain abdominal X-ray showed free subdiaphragmatic air. The patient underwent diagnostic laparoscopy with presumptive diagnosis of peptic ulcer perforation. Laparoscopy showed several inflamed, edematous jejunal loops with proximal obstruction and perforation by an impacted fish bone. Completely intracorporeal resection and anastomosis using laparoscopic linear stapler was performed and segment of resected bowel was removed through trocar site. Postoperative period was uneventful, and the patient was discharged on fourth day.

Endoscopic repair of rectal perforation due to colonoscopy with a clamp method

Colon perforation during colonoscopy is a rare complication that usually requires surgical intervention. Traditionally, primary repair by laparoscopy, laparotomy, resection, and anastomosis is performed for such perforations. More recently developed minimally invasive endoscopic instruments have also been used in the repair of these perforations; this is becoming increasingly common. An endoscopic over-the-scope clip clamp was used in a 59-year-old male patient who suffered a rectum perforation in connection with a diagnostic colonoscopy. He was referred to our clinic. A colonoscopy was performed in our clinic to assess the rectal perforation caused by a diagnostic colonoscopy 2 h after the initial colonoscopy, with the concurrent therapeutic purpose of repairing the perforation using an endoscopic clamping method. Oral feeding was started 24 h after the procedure. After three days, the patient was discharged. An endoscopic clamping method in appropriate cases can be a safe and appropriate alternative therapy in the management of colonoscopic perforations.

The effects of weight loss after sleeve gastrectomy on left ventricular systolic function in men versus women

PURPOSE

To evaluate and compare the effects of weight lost after sleeve gastrectomy on left ventricular (LV) systolic function using both two-dimensional speckle tracking (2D-STE) and three-dimensional echocardiography (3DE) in men versus women.

METHODS

In 53 obese patients referred for sleeve gastrectomy, 2D-STE and 3DE were performed prior to and 6 months after surgery.

RESULTS

The study included 53 obese patients (62.3% female; mean age 36.8 ± 10.7 years). Six months after surgery, all patients demonstrated a significant decrease in body mass index, body weight, blood pressure, heart rate, LV end-diastolic dimension, myocardial wall thickness, LV mass, LV mass index, LV mass/height(2.7) , LV end-diastolic volume, LV end-systolic volume, and stroke volume as well as an increase in SV index and ejection fraction. There was no significant difference in measured variables between men and women at baseline or postsurgery, except for baseline LV end-diastolic dimension, and baseline and after surgery LV mass, LV mass index, and LV mass/height(2.7) , which were all significantly higher in men.

CONCLUSIONS

Sleeve gastrectomy improves LV systolic function and contributes to reverse LV remodeling in both genders. © 2016 Wiley Periodicals, Inc. J Clin Ultrasound 44:492-499, 2016.

Evaluation of Serum Interleukin-17 (IL-17) Levels as a Diagnostic Marker in Pancreatic Adenocarcinoma

BACKGROUND

Inflammatory cytokines modulate immune responses in the tumor microenvironment during progression. The role of interleukin (IL-17) in cancer is currently under debate. This study was conducted to investigate the serum levels of IL-17 in patients with pancreatic adenocarcinoma (PA) and the relationship with tumor progression and known prognostic parameters.

MATERIAL AND METHODS

Thirty-five patients with PA were investigated. Serum samples were obtained on first admission before treatment and follow-up. Both serum IL-17 levels were determined using enzyme-linked immunosorbent assay (ELISA). Age- and sex-matched 35 healthy controls were included in the analysis.

RESULTS

The median age at diagnosis was 61 years, range 38-84 years; 21 (60%) patients were men. The tumor was located in the head of pancreas in 24 (69%) patients. The most common metastatic site was liver in 20 patients with metastasis (n = 18, 90%). The median follow-up time was 24.0 weeks (range 1.0-191.0 weeks). At the end of the observation period, 12 (34%) patients experienced disease progression and 23 patients (66%) were dead. Forty-four percent of 18 metastatic patients who received palliative chemotherapy (CTx) were CTx-responsive. Median progression-free survival and overall survival of the whole group were 13.7 ± 2.3 weeks [95% confidence interval (CI) = 9-18 weeks] and 48.0 ± 12.8 weeks (95% CI = 23-73 weeks), respectively. The baseline serum IL-17 levels were significantly higher in patients with PA than in the control group (p = 0.001). Moreover, serum IL-17 levels were significantly higher in the patients with large pathologic tumor status and low albumin levels (p = 0.04 and p = 0.03, respectively). However, serum IL-17 assays had no prognostic roles on outcome.

CONCLUSION

Although serum levels of IL-17 assays were found to be diagnostic value, no predictive and prognostic value was determined in PA patients.

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.

Giant juvenile fibroadenoma

Juvenile fibroadenoma is a common cause of breast masses seen in adolescents and young women. Giant juvenile fibroadenomas are usually single and unilateral. The etiology is thought to be due to increased levels of estrogen during adolescence, although it is not yet fully understood. Treatment options range from simple excision to sub-cutaneous mastectomy according to the size of the lesion. This article aimed to present a case that was diagnosed with "giant juvenile fibroadenoma".

Unilateral spontaneous adrenal hemorrhage in a young patient

The objective of this study was to report an unusual case of unilateral adrenal hematoma in; a 19-year-old young man who did not have a history of any specific systemic disease. The patient was admitted to hospital with chest pain that lasted for one day. Preoperative contrast-enhanced computerized tomography evaluated an adrenal mass (sized, 10.5 x 12.7 cm) adjacent to the anterior of the left kidney, and findings were indicative of adrenal hematoma. The final pathological diagnosis was adrenal adenoma.

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.

Comparison of open and laparoscopic appendectomy in uncomplicated appendicitis: a prospective randomized clinical trial

BACKGROUND

In the treatment of a subset of patients with uncomplicated appendicitis, no surgical method has been clearly established as superior.

METHODS

The present study was a prospective randomized clinical trial. Patients diagnosed with acute appendicitis were recruited for the study. Patients with a preoperative diagnosis of complicated appendicitis were excluded. The patients were randomly divided into two groups: a laparoscopic appendectomy group and an open appendectomy group. The primary outcome measure was the rate of postoperative septic complications. Secondary outcome measures were the length of hospital stay, postoperative pain score, and quality of life score.

RESULTS

Ninety-six patients were included in the study, 50 in the laparoscopic appendectomy group and 46 in the open appendectomy group. There were no significant differences between the two groups in terms of the rates of postoperative septic complications, hospital stay lengths, postoperative pain scores, or quality of life scores.

CONCLUSION

The laparoscopic approach to appendectomy in patients with uncomplicated appendicitis does not offer a significant advantage over the open approach in terms of length of hospital stay, postoperative pain score, or quality of life, which are considered the major advantages of minimally invasive surgery.

Management of acute appendicitis in pregnancy

BACKGROUND

Acute appendicitis is the most common surgical non-obstetric pathology during pregnancy. In this report, pregnant patients operated with a diagnosis of acute appendicitis in the last three years are evaluated retrospectively.

METHODS

Between January 2009 and January 2011, 20 pregnant patients were operated for acute appendicitis. Patients were evaluated regarding age, gestational age, clinical and laboratory examinations, imaging studies, operative findings, mean hospital stay, mean operative time, and outcome.

RESULTS

In 17 of 20 patients, acute appendicitis was confirmed and appendectomy was performed. Ten of the patients were operated with laparoscopic technique and the remaining 10 had open appendectomy. There was no fetal or maternal morbidity or mortality in any patient. All 20 patients delivered healthy babies during the postoperative course.

CONCLUSION

Acute appendicitis is a challenging diagnosis in the pregnant patient; however, early surgical intervention should be performed with any suspicion. The type of surgery depends on the surgeon's preference and experience.

The adaptation process of a teaching and research hospital to changing trends in modern breast surgery

OBJECTIVE

Minimally invasive surgery is increasingly gaining importance in breast surgery parallel to other surgical branches. Sentinel lymph node biopsy (SLNB) is a method that has radically changed the approach to breast surgery in the last decade of the 20(th) century. In this study, we aimed to evaluate the adaptation process to these alterations in breast surgery at our clinic.

MATERIAL AND METHODS

Patients who underwent surgery with a diagnosis of breast cancer in our clinic between April 2010 and November 2013 were retrospectively evaluated in terms of demographic characteristics, the number of operations and type of surgical methods applied according to years, SLNB performance rate, and results of frozen section and histopathological analysis. The first year of SLNB practice was accepted as part of the learning curve, and 24 patients who were operated during that period underwent routine axillary dissection.

RESULTS

The median age of 198 patients who were included in the study was 55 years (25-89). It was detected that the number of cases who underwent surgery for breast cancer increased in years, that the SLNB application rate increased from 37% to 66% between 2010 and 2013 (p=0.01), and SLNB staining rates increased from 70% to 94% (p=0.03). When only results from the last four years were evaluated, the mean staining rate in patients with SLNB (n=105) was 88% (n=92), with positive histopathology in 32% of these cases (n=30). Despite a decreasing trend over the years, a metastatic axillary lymph node was detected in paraffin block evaluation in spite of negative frozen section examination of SLNB in five cases, and 5 patients (5%) out of 97 patients who underwent breast conserving surgery required re-excision. The histopathological diagnosis was invasive ductal carcinoma in 84% (n=167) of patients.

CONCLUSION

It was observed that during the four-year period of adaptation, the application rate of breast conserving surgery and SLNB reached accepted standards, and that both the technical problems encountered in SLNB and the requirement for re-excision after breast conserving surgery significantly decreased with increasing case volume and experience.

Encapsulating peritoneal sclerosis as a late complication of peritoneal dialysis

Introduction

Encapsulating peritoneal sclerosis (EPS) is a rare cause of intestinal obstruction which is characterized by fibrotic encapsulation of the bowel. Although its pathogenesis is still not clear, many etiological factors have been stated.

Presentation of case

In this report, we present a 26-year old woman with peritoneal dialysis related EPS. Because of the unresolving intestinal obstructive symptoms, she underwent surgical intervention in which the thick dense whitish membranous sac was excised from the surrounding intestine along with adhesiolysis. She recovered uneventfully. She is symptom-free on the eight months of follow-up.

Discussion

EPS should be born in mind as a complication of the long term peritoneal dialysis in patients with progressive obstructive ileus and recurrent peritonitis. Its treatment either medically or surgically varies depending on the stage of this entity.

Conclusion

Early identification of EPS is important in order to achieve better prognosis.

•

We presented the patient experienced surgery because of encapsulating peritoneal sclerosis (EPS).

•

EPS should be born in mind as a complication of the long term peritoneal dialysis.

•

Diagnosis is primarily based on clinical finding, then generally confirmed by CT.

•

Early identification of EPS is important in order to achieve better prognosis.

Evaluation of the Probability of Non-sentinel Lymph Node Metastasis in Breast Cancer Patients with Sentinel Lymph Node Metastasis using Two Different Methods

OBJECTIVE

The aim of this retrospective clinical study was to evaluate the accuracy and feasibility of two different clinical scales, namely the Memorial Sloan-Kettering Cancer Center (MSKCC) nomogram and Tenon's axillary scoring system, which were developed for predicting the non-sentinel lymph node (NSLN) status in our breast cancer patients.

MATERIAL AND METHODS

The medical records of patients who were diagnosed with breast cancer between January 2010 and November 2013 were reviewed. Those who underwent sentinel lymph node biopsy (SLNB) for axillary staging were recruited for the study, and patients who were found to have positive SLNB and thus were subsequently subjected to axillary lymph node dissection (ALND) were also included. Patients who had neoadjuvant therapy, who had clinically positive axilla, and who had stage 4 disease were excluded. Patients were divided into two groups. Group 1 included those who had negative NSLNs, whereas Group 2 included those who had positive NSLNs. The following data were collected: age, tumor size, histopathological characteristics of the tumor, presence of lymphovascular invasion, presence of multifocality, number of negative and positive NSLNs, size of metastases, histopathological method used to define metastases, and receptor status of the tumor. The score of each patient was calculated according to the MSKCC nomogram and Tenon's axillary scoring system. Statistical analysis was conducted to investigate the correlation between the scores and the involvement of NSLNs.

RESULTS

The medical records of patients who were diagnosed with breast cancer and found to have SLNB for axillary staging was reviewed. Finally, 50 patients who had positive SLNB and thus were subsequently subjected to ALND were included in the study. There were 17 and 33 patients in Groups 1 and 2, respectively. Both the MSKCC nomogram and Tenon's axillary scoring system were demonstrated to be significantly accurate in the prediction of the involvement of NSLNs (p<0.05 for each). Among all the parameters, the only one that was found to be correlated with the risk of NSLN involvement was the presence of lymphovascular invasion.

CONCLUSION

The MSKCC nomogram and Tenon's axillary scoring system both seem to be reliable tools for the assessment of NSLN status in SLNB-positive breast cancer in our breast cancer population. Nevertheless, the omission of ALNB in SLNB-positive breast cancer cannot be yet recommended because of the lack of long-term results of current nomograms and scoring systems.

A Rare Entity of Breast Cancer: Primary Neuroendocrin Carcinoma

Breast cancer is the second leading cause of cancer throughout the world, however neuroendocrine tumors of the breast are rarely encountered. Herein we present a 75-year-old patient who was admitted to our clinic due to a mass in her breast and was operated on with a preliminary diagnosis of invasive breast carcinoma, However she was diagnosed with a neuroendocrine tumor after pathologic evaluation. The patient is the oldest one among others with a neuroendocrine tumor in the breast reported in the literature.

The early results of our initial experience with robotic adrenalectomy

OBJECTIVE

Robotic adrenalectomy is one of the minimally invasive surgical methods gaining wide acceptance due to the three-dimensional imaging system and ergonomics of the equipment. We aimed to present the early data on patients who underwent robotic adrenalectomy due to adrenal masses in our hospital.

MATERIAL AND METHODS

The records of eight cases, in which a unilateral robotic trans-peritoneal adrenalectomy was conducted due to an adrenal mass between 2011 and 2013, have been evaluated. Demographic characteristics of cases, body mass index (BMI), American Society of Anesthesiologists (ASA) score, preoperative diagnosis, diameter and localization of the adrenal mass, operative time, blood loss, conversion rate to open surgery, morbidity and mortality rates, length of hospital stay, total hospital charges and postoperative pathologic results were considered.

RESULTS

The female to male ratio was 6:2, the median age was 49.5 (26-71) and the median BMI was 29.7 (21.7-38.5). An adrenalectomy was performed in six cases for a right adrenal mass and in two cases for a left adrenal mass. The mean tumor diameter was 53.6 mm (20-90). The average surgical time (including docking) was 98 min. (55-175 min.) and the average blood loss was 50 mL. The only complication was a diaphragm injury which was repaired robotically. There were no conversions to traditional laparoscopic or open surgery and there have not been any mortality in the series. The median length of hospital stay was 4.1 days (range 2-11) and the average cost was 3617.12 TL ($1808.56).

CONCLUSION

Robotic adrenalectomy is an effective and safe surgical alternative to laparoscopic adrenalectomy. However its high cost has emerged as its main disadvantage.

The importance of defecography in the assessment of the etiology of chronic constipation: An analysis of 630 patients

OBJECTIVE

Chronic constipation is an entity with a high prevalence in the community. In our study, we analyzed the importance of defecography in the assessment of the etiology of chronic constipation.

MATERIAL AND METHODS

Patients who were admitted to our hospital outpatient general surgery clinic with complaints of constipation between July 2010 and January 2014, and who had their demographic data and defecography results recorded were included in the study. The demographic data of patients who underwent defecography and their results were recorded along with patient gender and age.

RESULTS

The defecography was abnormal in 573 patients (90.9%) while it was normal in 57 patients (9.1%).

CONCLUSION

Defecography is the current standard method of examination in etiological investigations for constipation, and it should be performed in each patient with a diagnosis of chronic constipation.

The chain of postoperative complications after laparoscopic cholecystectomy

Bile duct injuries are among the most dreadful complications of cholecystectomy. As laparoscopic cholecystectomy has become increasingly popular, the incidence of this complication increased and has remained unchanged in spite the learning curve being completed. A 50-year-old female underwent elective laparoscopic cholecystectomy for gallstone disease. A complicated bile duct injury occurred during the procedure. As the injury was immediately recognized, it was treated with concomitant hepaticojejunostomy. In the postoperative period, biliary fistula, which was assumed to be the result of an anastomotic leak, was encountered. Diagnostic and therapeutic percutaneous transhepatic biliary drainage was considered. It revealed that the anastomosis was intact and the source of biliary leak was an aberrant right posterior sectorial branch. A severe bleeding through the biliary catheter occurred due to transmigration of the catheter into the portal vein. Bleeding was controlled with embolization by the interventional radiologist. The patient thereafter was re-operated, and the leakage was sealed by ligation of the aberrant right posterior sectorial branch. The postoperative period was uneventful. As long as cholecystectomy is performed, bile duct injuries will always exist. Therefore, every abdominal surgeon should be aware of possible consequences of complications related to this procedure.

The growing role of laparoscopic repair in patients with early diagnosed peptic ulcer perforation

OBJECTIVE

Laparoscopy is gaining more importance in emergency abdominal surgery. Peptic ulcer perforation (PUP) constitutes a significant portion of surgical emergencies. The aim of this study was to evaluate the methods and results of patients who underwent surgery due to PUP in our department.

MATERIAL AND METHODS

Patients who were admitted to the hospital in the early period and received Graham-patch (GP) repair due to PUP from January 2009 to January 2013 were divided into two groups as laparoscopic (group L) or open (group O) surgery. Demographic data of the patients, duration of the operation, conversion to open surgery, length of hospital stay, secondary interventions, re-admissions, morbidity and mortality rates were retrospectively evaluated. Patients with conversion to open surgery were included in Group O.

RESULTS

Two hundred and nineteen patients were included in the study, 148 of which were in Group O (including the 47 patients with conversion), and 71 in group L. In patients with early admission, the rate of laparoscopically completed GP was 19.6% in the first year of the study, whereas this rate was 61.8% in the fourth year (p<0.001). The rate of conversion to open surgery was 50% in 2009, and 24.4% in 2012 (p=0.028). Length of hospital stay was shorter in group L (p=0.35). The complication rate was 4.2% in patients who had laparoscopic procedures, and was 6.1% in patients who underwent open surgery (p=0.57). Seventy-three percent (n=11) of re-hospitalized patients in the perioperative period (n=15) were treated conservatively. When costs related to secondary interventions and re-hospitalization were included, there was no significant difference between laparoscopic and open surgery groups in terms of cost (p=0.06).

CONCLUSION

Laparoscopic surgery for PUP is a reliable method and has been used increasingly over the years in our department. The operative time is longer, the length of hospital stay is shorter, the complication rates are less than open surgery, and the conversion rate is significantly reduced. Laparoscopic GP is feasible in early-admitted patients with PUP, due to the above-mentioned advantages. We believe the rate of conversion to open surgery decreases with increasing experience in laparoscopy.

Gastropleural fistula: a rare complication of ewing sarcoma

Gastropleural fistula (GPF) is a rare condition that can occur as a consequence of prior pulmonary surgery, trauma, or malignancy. Conservative management usually fails, and gastrectomy and even thoracotomy is often required, especially in debilitated patients. We present a patient with GPF who had a history of Ewing's sarcoma. Diagnosis of GPF was confirmed by upper gastrointestinal system endoscopy and radiographic contrast examination, and the patient underwent a laparoscopic wedge resection of the fistula. To our knowledge, this is the first report of a GPF, in the formation of which recurrence of Ewing's sarcoma had played a role and in the treatment of which wedge resection of the fistula was performed. Laparoscopic treatment of GPF may be associated with less morbidity and should be considered as the initial procedure of choice.

Prophylactic injection therapy is necessary for Forrest type 2b duodenal ulcers

BACKGROUND

We aimed to assess the effect of prophylactic injection therapy during the index gastroscopy on upper gastrointestinal bleeding due to Forrest type 2b duodenal ulcer.

METHODS

The patients who were admitted with upper gastrointestinal bleeding and who underwent emergency gastroscopy between January 2004 and January 2011 were recruited to the study retrospectively. Among those, the patients with Forrest type 2b duodenal ulcer were selected and divided into two groups. The patients in Group 1 had only diagnostic gastroscopy, whereas those in Group 2 had prophylactic injection therapy during the index gastroscopy.

RESULTS

Eighty-seven patients were included in the study. There were 41 patients in Group 1 and 46 patients in Group 2. There was a significant difference in the incidence of rebleeding (26.8% versus 6.5%, p=0.017). The mortality rate was similar in the two groups (9.7% versus 2.1%, p=0.184).

CONCLUSION

We recommend prophylactic injection therapy in patients with upper gastrointestinal bleeding who have Forrest type 2b duodenal ulcer.

A rare reason of abdominal compartment syndrome: non-Hodgkin lymphoma

Abdominal compartment syndrome (ACS) is characterized by intra-abdominal hypertension (IAH) which affects all body systems. In healthy individuals, normal intra-abdominal pressure (IAP) is <5 to 7 mmHg. The upper limit of IAP is generally accepted to be 12 mmHg. ACS has been classified into primary, secondary, and tertiary subtypes. Non-Hodgkin lymphoma (NHL) is a rare reason for ACS. We report here one case of NHL as a primary retroperitoneal mass in an 80-year-old male patient who presented with IAH.
