Pancreas transplantation: experience of single center.

BACKGROUND: Diabetes is the most common cause of renal failure. In patients with type I diabetes and renal failure,dialysis and insulin therapy can prevent a clinical context that causes rapid death, but they are insufficient to prevent longterm complications. Pancreas and islet cell transplantation inpatients with type I diabetes are the only curative treatment and have recently become more common. METHODS: Between December 2006 and August 2010 a total of 10 patients underwent pancreas transplantation. The patient's data were analysed retrospectively. RESULTS: 10 patients and their data were included in this study. Six patients were male and 4 patients were female. All patients are still alive, with functional grafts. CONCLUSIONS: Pancreas transplantation is the most effective treatment for patients with type I DM. This paper discusses the feasibility of this process and presents the experience of Ankara University in pancreas transplantation.

The effects of exercise on portal venous system in splenectomized adults.

OBJECTIVES: This study was designed to assess the effects of exercise on the portal venous system in splenectomized adults. BACKGROUND: Splenectomy is a surgical intervention commonly performed at surgery clinics and recognized as a cause of portal vein thrombosis. Intensive exercise increases blood flow to the contracting muscles, causes hypercoagulability and vasoconstriction in the splanchnic area, hence the portal vein diameter, blood flow velocity and discharge decrease. METHODS: Forty adults participated in this investigation. Subjects were trained to run for twenty minutes on a treadmill at a velocity of 6 km/h and ten-degree elevation. We compared the white blood cell count, portal vein diameter, portal venous blood flow velocity and discharge of splenectomized and healthy adults before and after exercise. RESULTS: After exercise, the blood leukocyte count was significantly increased and the portal vein diameter was significantly reduced in both groups (p<0.001) but there were no statistically significant differences between the two groups. The portal venous blood flow rate in splenectomy group were significantly lower than in the control group (p<0.001). Furthermore the portal venous blood flow rates in both groups were significantly reduced after exercise (p<0.001). CONCLUSION: Exercise in splenectomized individuals can cause serious problems in form of decreasing splanchnic flow and increasing blood viscosity. After splenectomy, both healthy individuals and patients with hematologic diseases ought to avoid intensive exercises (Tab. 2, Ref. 16).

Pancreatic cancer complicated by splenic infarction and abscess.

Pancreatic tail adenocarcinoma is both a diagnostic and therapeutic challenge. Despite technical and therapeutic advances, the prognosis remains dismal; the average survival time after diagnosis is characteristically only five to eight months. Both splenic infarction and abscess are very rare complications of pancreatic cancer. In this case of splenic infarction, the possible source of emboli should be carefully investigated. In addition, splenic abscess must be suspected in patients with splenic infarction, especially if the infectious signs persist despite appropriate treatment. Rapid diagnosis and treatment are essential as its course can prove fatal. The patient presented herein had a splenic infarct and abscess as complications of pancreatic tail carcinoma. The treatment of choice was splenectomy and distal pancreatectomy with resection of involved organs. The variability in clinical presentation and imaging studies warrants consideration of this entity in the differential diagnosis of many splenic and pancreatic lesions.

Effects of N-butyl-2-cyanoacrylate on high-level jejunojejunostomy.

BACKGROUND: Morbidity and mortality due to anastomotic complications in gastrointestinal surgery remain important problems. The tissue adhesive N-butyl-2-cyanoacrylate (NB2CA) is used in many fields of surgery. This study was designed to assess the effects of NB2CA on high-level jejunojejunostomy. MATERIALS AND METHODS: Forty male albino Wistar rats were divided into 4 groups of 10 each. The groups were treated as follows: group 1 underwent only a jejunojejunostomy, group 2 underwent jejunojejunostomy followed by NB2CA application around the anastomosis, group 3 underwent jejunojejunostomy after a 60-min ischemia and a 60-min reperfusion, and group 4 underwent jejunojejunostomy after a 60-min ischemia and a 60-min reperfusion followed by NB2CA application around the anastomosis. At postoperative day 7, the subjects in all groups were sacrificed. Intra-abdominal adhesions, anastomotic complications and anastomotic burst pressures (ABP) were recorded. RESULTS: The analysis of all the groups for adhesion scores and ABP showed statistical significance (p < 0.001). CONCLUSIONS: The use of NB2CA had positive effects in terms of increasing ABP both with and without the initial ischemia- reperfusion insult. However, it had the adverse effect of significantly increasing the number of intra-abdominal adhesions.

A very late-onset deep infection after prosthetic inguinal hernia repair.

Prosthetic repair of inguinal hernias has low recurrence and infection rates in practice. However, surgical site infection is still a potential complication. A limited number of cases have been reported to date describing late-onset deep mesh infection following prosthetic repairs. We herein report a new case of postherniorrhaphy infection with a very late onset.

Primary biliary cystadenocarcinoma mimicking a complicated hydatid cyst.

Cystadenocarcinoma of the liver is a rare neoplasm that originates from hepatobiliary epithelium. Primary location of this tumor is generally intrahepatic and most cases are in the right hepatic lobe. Herein we present a case of intrahepatic cystadenocarcinoma in a 53-year-old man who had been followed up for 8 years as hydatic cyst disease of the liver. He was admitted to our hospital with jaundice and loss of appetite. Ultrasound and computed tomography showed a cystic lesion that looked like type II cyst hidatic. Thereafter magnetic resonance imaging revealed a cystic lesion associated with biliary tree. On diagnostic laparotomy peritoneal infiltrations were observed and pathologic examination revealed a biliary cystadenocarcinoma and peritonitis carcinomatosa was diagnosed. Unfortunately correct diagnosis was extremely late and no curative management was possible.

Basic fibroblast growth factor loaded polypropylene meshes in repair of abdominal wall defects in rats.

BACKGROUND AND AIM: Incisional hernia following laparotomy and recurrent herniation after its repair are still common problems in spite of mesh augmentation. The underlying biological mechanism may be related to collagen metabolism. Recently, some members of growth factors family have been tested in the prevention of wound failure and incisonal hernia formation. Growth factors may promote fibroblast proliferation and collagen deposition. In the present study, we searched the effects of basic fibroblast growth factor (bFGF) loaded polypropylene meshes in an incisional hernia model in rats. METHODS: A total of 80 Wistar albino rats were randomly divided into five groups. A uniform surgical procedure was employed in all groups: a 5 cm skin incision was made at the midline and a full segment of the abdominal wall sized 3 x 2 cm was excised. Abdominal wall was closed with rapidly absorbable 3/0 catgut. Following this standard surgery, five different procedures were applied to the groups before closing the skin with 4/0 monofilament polypropylene sutures. Control subjects (Group 1) received no extra procedure after abdominal wall suturing. Polypropylene meshes were used in onlay position by fixing 4/0 monofimalent polypropylene interrupted sutures in other four groups. A standard mesh with no chemical treatment was used in Group 2. Gelatin coated meshes were used in Group 3, while Group 4 and 5 received bFGF loaded meshes with 1 microgram (microg) and 5 microg doses respectively. All the groups then divided into 1st month (early: E) and 2nd month (late: L) subgroups (n=8 each) according to sacrification dates. Tensiometric and histopathological evaluations were done. The specimens for histopathology were obtained from the interface area of the meshes and stained with hematoxylin and eosin, and also Masson trichrome. The variables were examined and evaluated by a single blinded pathologist under light microscopy in respect of inflammation, vascularization, fibroblast activity, collagen fibers and connective tissue organization. The avidin-biotin-peroxidase method was performed using the primary monooclonal antibodies against collagen type I and collagen Type III. RESULTS: bFGF loaded meshes showed higher tensile strength values in comparison with a standard polypropylene mesh after 2 months. Histopathological and immunohistochemistry studies also revealed somewhat better scores in favor of bFGF loaded mesh over a standard polypropylene mesh. These limited effects of bFGF did not seem to be dose dependent. CONCLUSIONS: The use of bFGF loaded polypropylene mesh in the abdominal wall healing may cause somewhat higher tensile strength values in comparison with a standard polypropylene. However, histopathological and immunohistochemistry studies revealed only a slightly better healing in favor of bFGF loaded mesh over a standard polypropylene mesh.

Partial cholecystectomy is a safe and efficient method.

AIM: When there is excess inflammation, fibrosis and portal hypertension around gall bladder or in presence of Mirizzi syndrome, bile ducts and hepatic artery may be possibly damaged during dissection of Calot triangle. In this study, we examined safety and efficiency of partial cholecystectomy operation which we perform when dissection of Calot triangle is challenging. METHOD AND MATERIAL: Eighteen patients who were undergone partial cholecystectomy in our clinic between 1996 and 2008 were retrospectively evaluated. Mean age of patients was 66 years (range: 55-88 years) and ratio of male/female was 2/1 (12 men, 6 women). Fourteen patients were undergone general anesthesia, whereas 4 patients were operated under epidural anesthesia. Partial cholecystectomies were performed by right subcostal incision in 16 patients and by right paramedian incision in 2 patients. RESULTS: No intra-operative or early post-operative mortality was found among patients. Post-operative subhepatic abscess occurred in one patient (5.5%) and superficial wound site infection occurred in 4 patients (22,2%). Controlled bile fistula occurred in early post-operative period in two patients (11.1%) and fistula spontaneously closed without requiring additional surgical procedure. Escherichia coli were most common microorganism found in bile culture. Mean hospitalization period of patients was 8 days (range: 15-14 days) and mean follow-up period was 80 months (8-150 months). During follow up, hepatobiliary ultrasonography could be re-performed in 8 patients and no new stone formation was observed. In 7 patients, it was understood verbally that no postoperative gastrointestinal symptoms were present. CONCLUSION: Where dissection of Calot triangle is changeling, partial cholecystectomy can be safely and efficiently performed.

A late onset carotido-jugular fistula following shotgun injury.

The incidence of arteriovenous fistulae (AVF) is quite rare in the head and neck region comprising less than 4% of all the traumatic AVF encountered elsewhere in the body. A 42-year-old man presented with a palpable thrill in the cervical region and headache. He had a shotgun injury 10 years ago and had no problem until the previous three months. Diagnosis of a high output traumatic AVF between right common carotid artery and internal jugular vein was made arteriographically. Presence of a neighbouring traumatic aneurysm on the common carotid artery and 9 mm diameter of the fistula tractus suggested open surgery. At the operation ligation of the tractus and aneurysmorraphy was performed and the patient was discharged in the third postoperative day. He has still no problem. This case documented that a shotgun injury even 10 years later may result with an AVF.

Delayed presentation of a traumatic diaphragmatic rupture with intrapericardial herniation.

Thoracic and abdominal blunt traumas are the major causes of diaphragmatic rupture. These ruptures may be recognized at the time of the initial trauma, but are diagnosed months or even years later during the workup for related symptoms. We present herein a patient who suffered from abdominal pain and dyspnea years after a motor vehicle accident. A chest computed tomography (CT) demonstrated diaphragmatic rupture with intrapericardial herniation of intraabdominal organs. Exploratory laparotomy confirmed the diagnosis. In this report, we describe our management of this unusual diaphragmatic rupture.

Pure laparoscopic versus open live donor nephrectomy: evaluation of health survey and graft functions.

BACKGROUND: Laparoscopic donor nephrectomy (LDN) has become the gold standard in many kidney transplantation centers seeking to increase the number of potential live donors. This study was designed to compare the health surveys and graft functions between LDN and open donor nephrectomy (ODN). METHODS: We retrospectively analyzed all patients who underwent donor nephrectomy between December 2005 and September 2009 who had at least 1 year of follow-up. We reviewed demographic data, operative time, warm ischemia period, graft function, and quality of life. RESULTS: Among the 132 cases, 98 were pure LDN and 34 were ODN. Demographic data were similar in both groups. Operative times were significantly longer in the ODN group but warm ischemia times significantly longer in the LDN group. However, graft functions were similar in both groups. There was 1 graft loss due to arterial thrombosis of the transplanted kidney among the LDN group. Short-Form 36 health survey scores were similar except for the role-physical subscale. CONCLUSION: Although we failed to observe a significant difference between ODN and LDN as far as the quality of life and graft functions were concerned, the previously documented advantages of laparoscopy with similar operative results suggest? LDN to be the gold standard for this procedure in our institution.

Living-donor hepatectomy.

BACKGROUND: Organ transplantation from deceased donors is still far below the need. Because of this deficiency, liver transplantations are performed mostly from live donors in many transplant centers in our country. Living-donor liver transplantation (LDLT) has evolved dramatically over the past decade. The aim of this study was to present our clinical experience with living-donor hepatectomy. METHODS: We retrospectively analyzed all patients who underwent donor hepatectomy between March 2000 and September 2010. We reviewed demographic data, operation type, operation and cold ischemia times, duration of hospital stay, and postoperative complications. RESULTS: During the study period, 140 living donors underwent operations for liver transplantation. We performed 108 right hepatectomies, 17 left hepatectomies, and 15 left lateral hepatectomies. The mean age of the donors was 30.8 years. There was no operative or postoperative mortality. Overall morbidity rate was 13.57% (n = 19). Nine patients had biliary leakages, 4 biliomas; 2 urinary tract infections, and 1 each inferior vena caval injury, pneumonia, portal vein thrombosis, and acute tubular necrosis. Reoperation was not required in any of these patients. CONCLUSIONS: Living-donor liver transplantation is a valuable alternative for patients awaiting a cadaver organ. Live-donor hepatectomy can be performed with low morbidity. The greatest disadvantage of this procedure is the risk of the surgical operation for the individual who will experience no medical benefit from this procedure.

Single stapler technique in laparoscopic donor nephrectomy.

BACKGROUND: Laparoscopic donor nephrectomy (LDN) is usually performed with at least 2 separate vascular staplers for division of the renal artery and vein. However, we used a single stapler regardless of the number of renal arteries and veins. Furthermore, the graft was quickly retrieved by hand without using an extraction bag using our technique. Herein we have presented our experience with LDN of grafts with single or multiple renal arteries and/or veins using a single stapler and hand removal. METHODS: We reviewed demographic data, operative and warm ischemia times, postoperative complications, and graft function. RESULTS: Between December 2005 and September 2009, we performed 85 cases with 1 renal artery (group LDN-1), 8 cases with two renal arteries (group LDN-2), and 5 cases with 3 or more renal arteries (group LDN-3). The demographic data among the groups were similar. The mean operative time was significantly longer among groups LDN-2 (100.3 ± 9.5 minutes) and LDN-3 (120.6 ± 10.3 minutes) compared with LDN-1 (76.1 ± 9.3 minutes; P < .001). Similar results were observed with respect to warm ischemia times. There were no significant differences related to graft function and outcomes among these groups. CONCLUSION: The single stapler and hand removal technique was safe, technically feasible, and cost effective regardless of the number of renal arteries and veins. This technique removes the necessity of additional staplers and extraction bags, lowers the operative and warm ischemia times, and thus decreases the cost.

Evaluation of the therapeutic use of antibiotics in Aegean Region hospitals of Turkey: a multicentric study.

PURPOSE: The antibiotic restriction policy has been validated nationwide since February 2003 by the Ministry of Health because the excessive consumption of antimicrobials causes a high cost. The aim of this study was to evaluate the therapeutic use of antibiotics in Aegean Region hospitals and to assess the impact of this nationwide antibiotic restriction policy. This new policy is based on justification that the infectious disease (ID) physicians should be primarily responsible for the prescription of antimicrobials. MATERIALS AND METHODS: Eight university and government hospitals were included in the study. The criteria of the Council for Appropriate and Rational Antibiotic Therapy (CARAT) were considered. Both patient-based and antibiotic-based analyses were performed. For the analysis of inappropriate use, logistic regression was modeled. RESULTS: Therapeutic use was determined in 540 patients by a total of 29 ID physicians.In the study, 30.2% of the patients were given antimicrobials and empirically started antibiotics accounted for 79% cases of therapeutic antibiotic use, and 60% of those were inappropriate (P = 0.001). The appropriate use of ID level antibiotics (P = 0.000) were very compatible with other antimicrobial groups. CONCLUSION: The study shows that the Turkish government's new intervention policy on antimicrobial prescribing has been effective.

Gynecologic symptoms and sexual function in female kidney allograft recipients.

BACKGROUND: There is little information in the literature about changing menstrual patterns, sexuality, and fertility after kidney transplantation. The purpose of this study was to describe gynecologic symptoms, menstrual characteristics, sexual functions, details of pregnancies and gynecologic care before and after women underwent renal transplantation. METHODS: A detailed Turkish questionnaire was prepared for gynecologic evaluation. Fifty women of reproductive age who underwent renal transplantation took part in this study. The questionnaires were filled out at the time of the postoperative follow-up. RESULTS: The mean age and body mass index of all study participants at the time of interview was 33.9 years (range, 18-52) and 23.5 kg/m(2) (range, 16.5-33.3), respectively. There were no differences between bleeding between periods, heavy period, painful period, and period duration before and after transplantation. Eight women left active working life after grafting on their own accord. Thirteen women ceased sexual activity after transplantation. None of the women reported pregnancy after grafting. A total of 98% of women reported that they were never instructed about regular gynecologic care. CONCLUSION: We found that restrictions in the lives of women with transplanted kidneys included ceasing sexual activity and leaving active working life and that these were due to fear of possible organ damage. Women with transplanted kidneys must be informed about posttransplant sex life and the requirement for regular examinations by a gynecologist. Hence, close collaborations should be formed between patients, primary care physicians, and gynecologists.

The effects of polypropylene mesh on femoral artery and femoral vein in mesh repair.

PURPOSE: Since the first description, the use of polypropylene mesh in hernia repair has gained wide acceptance. The aim of this study was to assess whether polypropylene mesh implantation has any effects on femoral blood vessels. METHODS: A 0.5 × 1.0 cm polypropylene mesh was inserted into the rat femoral artery and vein on the right side. After 14, 28 and 90 days, the rats were reoperated. The meshes were excised for histological processing. Blood flow in the dorsum of the foot skin, femoral artery and vein were measured in all groups before mesh implantation and at 14, 28, and 90 days after mesh implantation. RESULTS: Following placement of mesh graft on vascular structures, inflammation and fibrosis developed to a varying degree depending on the time elapsed. On the other hand, fibrosis did not change the histological structure of vessels. There was a decrease in both arterial and venous circulation due to the pressure of the graft. CONCLUSIONS: These data suggest that fibrosis due to mesh graft can negatively affect blood flow in vessels due to mechanical pressure.
