Laparoscopic cholecystectomy in patients aged 80 years and older: an analysis of 111 patients.

INTRODUCTION: The incidence of cholelithiasis increases with age. More octogenarian (≥80 y) patients are undergoing laparoscopic cholecystectomy (LC) operation throughout the world. PATIENTS AND METHODS: A retrospective study was conducted on patients older than 80 years (group 1: 111 patients) and those in the 18 to 79 years age group (group 2: 185 patients), who underwent LC between July 2005 and October 2009. The variables analyzed were the presentation, demographics, comorbid illnesses, American Society of Anaesthesiology (ASA) scores, history of previous abdominal surgery, the operative time, postoperative morbidity and mortality, and the length of hospital stay. A comparison was made between the two groups. Data was evaluated by using the χ and the Fisher exact test. P<0.005 was considered significant. RESULTS: The difference in both groups in the mean age and ASA scores were significant. The indication for LC was gallstone disease in 87 (78.4%) patients, acute cholecystitis in 16 (14.4%), and gallstone pancreatitis in 8 (7.2%) of group 1 patients. The conversion rate was not statistically significant. The mean operative time was 77 minutes in group 1 patients, and this was significantly longer than that of group 2 patients. The postoperative oral intake within 24 hours of surgery was significantly earlier in group 2 patients. Other parameters were not significantly different between the 2 groups. CONCLUSIONS: LC in octogenarians is a relatively safe procedure that can be performed with low morbidity and mortality rates. The comorbidities and higher ASA scale are major risk factors for postoperative complications in this age group of patients.

Acute small bowel obstruction due to ileal endometriosis: a case report and review of the most recent literature.

INTRODUCTION: Endometriosis is defined as the presence of benign endometrial glands and stroma outside the normal anatomical location. Endometriosis of the small bowel, especially symptomatic small bowel involvement, is very unusual. CASE REPORT: We presented a 45-year-old woman with acute intestinal obstruction due to ileal endometriosis The patient complained of severe abdominal pain, nausea and vomitting. Immediate laparotomy was carried out. Above the ileocecal valve there was an ulcerated, edematous and fragile segmental lesion that caused intestinal obstruction. Histology of this ileal segment revealed endometriosis and an annular stricture that again showed foci of endometriosis. CONCLUSION: In reproductive-age women with the symptoms of intestinal obstruction, intestinal endometriosis should be kept in mind.

Determinants of postoperative hypocalcemia in vitamin D-deficient Graves' patients after total thyroidectomy.

BACKGROUND: The etiology of postoperative hypocalcemia after total thyroidectomy appears to be multifactorial, that is, postoperative transient hypoparathyroidism, low 25-hydroxy vitamin D (25-OHD) concentrations, aging, and hyperthyroidism with increased bone turnover. Our aim was to evaluate the factors responsible for postoperative hypocalcemia in euthyroid vitamin D-deficient/insufficient Graves patients who underwent total thyroidectomy at our institution. METHODS: Thirty-five consecutive patients with Graves disease treated by total thyroidectomy were included in the present study. All patients were vitamin D deficient/insufficient (ie, 25-OHD concentrations of <20/<30 ng/mL, respectively). Patients were divided into 2 groups according to postoperative serum albumin corrected calcium concentrations: group 1 (n = 13) patients had postoperative serum calcium concentrations of 8 mg/dL or less; group 2 (n = 22) patients had serum calcium concentrations greater than 8 mg/dL. Bone turnover markers (deoxypiridinoline, bone-specific alkaline phosphatase) and 25-OHD were determined the day before surgery. RESULTS: In group 1 patients, disease duration was significantly longer, 25-OHD and postoperative parathyroid hormone concentrations were significantly lower, and bone turnover markers were significantly higher. Logistic regression analysis revealed that a postoperative parathyroid hormone concentration less than 10 pg/mL was the most powerful parameter to predict postoperative hypocalcemia (odds ratio, 23; 95% confidence interval, 3.3-156). CONCLUSIONS: In Graves patients with vitamin D deficiency/insufficiency, postoperative (transient) hypoparathyroidism is the most significant parameter to determine the development of postoperative hypocalcemia.

Gallbladder perforation: clinical presentation, predisposing factors, and surgical outcomes of 46 patients.

BACKGROUND/AIMS: We aimed to investigate the clinical features and the relation between patient characteristics and the different types of gallbladder perforation and to determine the predisposing factors. MATERIAL AND METHODS: The medical records of 478 patients who received urgent surgical treatment with the diagnosis of acute cholecystitis and underwent urgent surgery in our clinics between January 1997 and November 2008 were reviewed retrospectively. The demographic data of patients, time elapsed from the onset of the symptoms to the time of surgery, comorbidity status, American Society of Anesthesiologists classification, laboratory data, imaging results, surgical procedures, postoperative complications, and postoperative length of stay of the patients were analyzed. RESULTS: There were 46 (9.6%) patients with the diagnosis of gallbladder perforation. Morbidity and mortality occurred in 15 (32.6%) and 7 (15.2%) patients, respectively. Advanced age, male gender, fever >38°C, high white blood cell count, and presence of cardiovascular comorbidity were found to be significant risk factors for gallbladder perforation. CONCLUSIONS: While early diagnosis and early surgical intervention are the keys to managing gallbladder perforation, we suggest that patients having the above-mentioned clinical features should be carefully investigated.

[Prognostic factors for hospital mortality in patients with acute mesenteric ischemia who undergo intestinal resection due to necrosis]. / Nekroz nedeniyle bagirsak rezeksiyonu uygulanan akut mezenterik iskemili olgularda hastane mortalitesi için prognostik faktörler.

BACKGROUND: The purpose of this study was to review our experience in patients with acute mesenteric ischemia (AMI) and to identify prognostic factors associated with hospital mortality. METHODS: Clinical data of patients with AMI were reviewed and analyzed retrospectively. A total of 67 patients (34 female, overall mean age 66 years) were evaluated in the study. RESULTS: Small bowel necrosis was detected in all patients, while colonic involvement was present in 21 (31.3%). Necrosed small bowels were resected in 59 (88%) in the first intervention. Embolectomy was also performed in 2 (3%) of these cases. Anastomosis was established in 22 (32.8%). Second-look operation was performed in 31 (46.3%) and primary resection and re-resection were performed in 8 (11.9%) and 11 (16.4%) patients, respectively. Hospital mortality rate was 56.7% (n=38). Logistic regression analysis showed prolonged symptom duration (>24h) (p=0.000), sepsis (p=0.022) and colonic necrosis accompanied with small bowel necrosis (p=0.002) as the independent prognostic factors in hospital mortality. CONCLUSION: AMI has a high hospital mortality rate due to late diagnosis and sepsis. Another risk factor is colonic involvement. Early evaluation in high-risk patients and resection for necrosed intestinal segments as soon as possible prior to sepsis may reduce the hospital mortality rate.

Preventive effect of pentoxifylline on acute radiation damage via antioxidant and anti-inflammatory pathways.

PURPOSE: The aim of the present study was to investigate whether pentoxifylline (PTX) treatment could protect against induced acute radiation enteritis. METHOD: Rats received 100 mg/kg/day PTX for 7 days before irradiation and continued on treatment for 3 days after irradiation. The intestinal myeloperoxidase (MPO) activities and malondialdehyde (MDA), glutathione (GSH), prostaglandin E2, and thromboxane B2 levels were determined. Terminal ileum tissue was evaluated for morphological changes. Also, nuclear factor kappa (NF-kappa), tumor necrosis factor-alpha (TNF-alpha), and intercellular adhesion molecule 1 (ICAM-1) expressions were analyzed with immunohistochemisty methods. RESULTS: PTX treatment was associated with increased GSH levels and decreased MPO activity and MDA, prostaglandin E2, and thromboxane B2 levels. Histopathologic examination showed that intestinal mucosal structure was preserved in the PTX-treated group while having significant decreases in NF-kappaB, TNF-a, and ICAM-1 expression. CONCLUSIONS: PTX appears to have a protective effect against radiation damage. This protective effect is mediated in part by decreasing both inflammatory reactions and oxidative stress.

Effect of sildenafil on wound healing: an experimental study.

PURPOSE: We aimed to investigate the effect of sildenafil on the healing process of abdominal wall wound in rats. MATERIALS AND METHODS: The study was performed with adult female Wistar-Albino rats. Control group (n = 50) were fed on standard laboratory diet until 12 h before surgery. Study group (n = 50) were applied orally with orogastric tube 10 mg/kg once a day for 10 days of sildenafil therapy. Each rat was anesthetized, and a 4-cm-long midline laparotomy was performed. Ten animals from each group were killed at postoperative days (PODs) 4, 7, 14, 21, and 35. Breaking strength analysis was measured, and the abdominal incision wounds were examined histologically. RESULTS: Breaking strength for the midline incision, acute inflammation score on POD 14, and neovascularization on PODs 7, 14, 21, and 35 were significantly higher in the study group. CONCLUSIONS: Sildenafil can be used as a supporting factor in wound healing.

[Outcomes of surgical therapy and prognostic factors in spontaneous gastric tumor perforation]. / Mide tümör perforasyonlarinda cerrahi tedavi sonuçlari ve prognostik faktörler.

BACKGROUND: The aim of the present study was to evaluate the clinicopathological features in patients with perforated gastric cancer, to point out the surgical approaches, and to analyze the factors that affect morbidity and mortality. METHODS: The data of 24 patients with perforated gastric cancer who underwent emergency intervention between 1996 and 2006 were retrospectively analyzed. The overall age was 60.6 years, and 62.5% of the patients were male. RESULTS: The tumor was localized at the antrum most frequently (66.7%), and stage IV disease was present in 66.7% of the patients (n = 16). Concomitant disease was present in 58.3% of the patients (n = 14). In 54.2% of patients (n = 13) primary repair and omentopexy, in 20.8% (n = 5) D0 or D1 total gastrectomy, in 8.3% (n = 2) D0 subtotal gastrectomy, in 8.3% (n = 2) D0 wedge resection, and in 8.3% (n = 2) staged D2 total gastrectomy were performed. The morbidity rate was 29.2% (n = 7) and the mortality rate was 25% (n = 6). Multivariant analysis showed that diffuse peritonitis and the period between perforation and operation (longer than 24 hours) were effective on prognosis, either on morbidity (p = 0.002 and p = 0.002, respectively) or on mortality (p = 0.009 and p = 0.000, respectively). CONCLUSION: Postoperative morbidity and mortality rates are high in patients with perforated gastric cancer. In resectable cases, one-stage radical gastrectomy should be encouraged if conditions allow. In patients with diffuse peritonitis and poor general condition, palliative surgery or staged radical gastrectomy should be considered. High rates of mortality and morbidity can be reduced with early diagnosis and with the surgical control of gastric perforation before peritonitis.

Cardiovascular risk in patients with nonfunctional adrenal incidentaloma: myth or reality?

BACKGROUND: It is not clear whether nonfunctional adrenal incidentaloma (NFA) increases the risk of atherosclerosis and metabolic syndrome or whether this type of adrenal tumor has been found more frequently in patients with cardiometabolic risk factors. We aimed to determine the effects of NFA on cardiometabolic risk factors and endothelial function and to compare the patients with a 1:1 cardiometabolic risk factor matched control group. METHODS: Thirty-five patients with NFA were studied, and 35 body mass index-, age-, and sex-matched subjects were regarded as group 2 controls. Thirty-five cardiometabolic risk factors-matched subjects were then regarded as group 3 controls. RESULTS: Patients with NFA had significantly lower flow-mediated dilation (FMD)-a parameter for endothelial function-measurements compared with groups 2 and 3 (7.1 +/- 2.9% vs. 12.9 +/- 3.8% and 13.5 +/- 4.5%; P < 0.02). Frequency of metabolic syndrome was also significantly higher in NFA patients than in control groups 2 and 3 (31.4, 5.7, and 20.0%, respectively; P < 0.05). Age (Odds Ratio [OR] = 2.9), total cholesterol (OR = 2.3), and presence of adrenal incidentaloma (OR = 10) were significant independent predictors of lower FMD (P < 0.05 for all). CONCLUSIONS: Patients with NFA have increased prevalence of metabolic syndrome and impaired endothelial function compared with 1:1 cardiometabolic risk factor-matched controls.

Early prediction of hypocalcemia after thyroidectomy by parathormone measurement in surgical site irrigation fluid.

BACKGROUND: Improvements in surgical technique cannot eliminate the risk of hypocalcemia. We aimed to evaluate the accuracy of PTH levels in surgical site irrigation fluid (irPTH) in predicting patients at risk for postoperative hypocalcemia. METHODS: Prospective analysis of 160 consecutive patients undergoing thyroidectomy was performed. Patients were divided into 2 groups based on postoperative serum calcium levels. Patients with hypocalcemia were assigned to Group 1 (n=38), while those with normocalcemia were assigned to Group 2 (n=122). Preoperative and postoperative serum calcium levels and PTH level of surgical site irrigation fluid (irPTH), and the difference in serum calcium levels before and after thyroidectomy were determined. RESULTS: The difference in serum calcium levels and irPTH levels in Group 1 were significantly higher than those in group 2 (p=0.001). There was a negative correlation between postoperative serum calcium level and irPTH level (r=-0.641, p=0.0001). Patients who had irPTH level higher than 250 pg/mL had a 69-fold increased risk for postoperative hypocalcemia (OR=69.88; 95% CI: 15.37-309.94). CONCLUSIONS: High irPTH level is significantly associated with postoperative hypocalcemia. The irPTH assay is sufficient to identify hypocalcemia in the majority of patients and it is a sensitive tool to identify patients at risk of developing postoperative hypocalcemia.

Asymptomatic occult cysto-biliary communication without bile into cavity of the liver hydatid cyst: a pitfall in conservative surgery.

BACKGROUND: An occult cysto-biliary communication in liver hydatid disease is still a major problem in surgical practice. Radiologic and intraoperative findings may not be helpful to detect cysto-biliary communications in some asymptomatic patients with liver hydatid disease. Biliary leakage is a troubling complication that arises after conservative surgery in patients who have occult "insidious" cysto-biliary communications. We aimed to identify the factors which are associated with the risk of occult insidious cysto-biliary communications in patients preoperatively who developed biliary leakage after surgery. PATIENTS AND METHODS: We investigated the records of 183 asymptomatic patients treated for liver hydatid cyst and analyzed potential predictors of occult insidious cysto-biliary communication, retrospectively. RESULTS: There were 115 female and 68 male patients; the mean age was 42.3 years. Occult insidious cysto-biliary communications which presented as postoperative biliary leakage found in 24 (13.1%). Independent clinical predictors were alkaline phosphatase >133 U/L, total bilirubin levels >1.2 mg/dL, white blood cell count >10,000/mm(3) and cyst diameter >10 cm on multivariate analysis. Seventeen of 24 were low output biliary fistula which resolved spontaneously within 9.2 days. The remaining 7 were high output biliary fistula for which endoscopic sphincterotomy was performed in all patients, fistulas resolved within 22.6 days. Average interval between endoscopic sphincterotomy and fistula closure was 10.3 days. Mean hospital stay was longer in patients with biliary leakage than in those without (9.8 vs. 4.2 day p<0.001). There was no hospital mortality. CONCLUSION: The predictors demonstrated in this study should allow the likelihood of occult insidious cysto-biliary communication to be determined and, thus, indicate the need for additional procedures during operations to prevent the complications of biliary leakage.

[Traumatic extracranial carotico-juguler fistulation]. / Travmatik ekstrakraniyal karotiko-juguler fistüller.

BACKGROUND: Extracranial caroticovenous fistulae, if left untreated, may cause stroke, cerebral edema, and high output cardiac failure and may present with oculofacial signs. In this study, 5 cases with extracranial arteriovenous fistulae who were diagnosed and surgically treated promptly after trauma are presented. METHODS: Five patients with extracranial traumatic caroti-cojuguler fistulation underwent urgent surgery in our department. Their mean age was 32.4 (range: 27-38). Mean door to operating room time was 2.4 hours. One patient underwent arcus aortography due to a large hematoma in the mediastinum. One patient underwent arterial Doppler ultrasound examination. The remaining three patients were diagnosed via physical examination. RESULTS: There were three gunshot and two stab wounds. The right common carotid artery was injured in three cases and left common carotid artery in two. There was no early or late mortality. Cross-clamp time was 14.3+/-4.7 minutes. There was no major bleeding. One patient developed ischemic stroke secondary to hypotension due to massive bleeding before surgery and was transferred to the Department of Neurology on the 5th postoperative day. CONCLUSION: We suggest that as soon as the diagnosis of traumatic caroti-cojuguler fistula is made, a surgical approach is effective and safe and may prevent possible complications due to delayed diagnosis and treatment.

Does near total thyroidectomy offer advantage over total thyroidectomy in terms of postoperative hypocalcemia?

Total thyroidectomy (TT) has emerged as a surgical option in the surgical treatment of patients with multinodular goiter. TT carries potential risk to all parathyroid glands and both recurrent laryngeal nerve. The aims of this study are to evaluate the difference between serum calcium levels before and after total and near total thyroidectomy and to compare the rate of postoperative hypocalcemia according to surgical procedures. This prospective study included 143 consecutive patients undergoing surgical therapy for non-toxic multinodular goiter. Patients were randomly assigned to surgical procedures. Patients in group 1 (n=75) performed TT, and patients in group 2 (n=68) performed near total thyroidectomy (NTT). The difference between serum calcium levels and percentage decrease in serum calcium levels before and after thyroidectomy were calculated. TT had a 33-fold (OR: 33.1; 95% CI: 7.5-145.02) increased risk for hypocalcemia. Moreover, TT had a 8-fold (OR: 8.09; 95% CI: 3-21.4) and a 27-fold (OR: 27.9; 95% CI: 3.5-219.6) higher risk than NTT for moderate and severe percentage decreases in serum calcium level, respectively. NTT can offer an advantage over TT in terms of postoperative hypocalcemia in the patients with benign multinodular goiter.

Analysis of early relaparotomy after lower gastrointestinal system surgery.

PURPOSE: To evaluate the complications after lower gastrointestinal system (GIS) operations, and to investigate the reasons for and outcomes of relaparotomy (RL), and the factors influencing its mortality rate. METHODS: The subjects of this retrospective study were 38 patients who underwent early RL for complications of lower GIS surgery. We analyzed the demographic features and initial diagnoses of the patients, the reasons for their initial surgery and their postoperative complications, and the number, duration, and outcome of early RLs. RESULTS: The average patient age was 54.8 +/- 16.2 years and the male:female ratio was 30:8. Early RL was performed for the following complications: leakage of an intestinal repair or anastomosis (n = 17, 44.7%); intraabdominal infection or abscess (n = 8, 21%); stomal complications (n = 5, 13.2%); necrosis caused by mesenteric arterial thrombosis (n = 4, 10.5%); hemorrhage (n = 2, 5.3%); and intestinal rupture (n = 2, 5.3%). A mortality rate of 36.8% (n = 14) was attributed mainly to infections (n = 27, 71.4%). The average interval between the first laparotomy and RL was 5.5 +/- 3.5 days, and the average hospital stay was 27.1 +/- 19.4 days. CONCLUSIONS: Relaparotomy performed soon after major lower GIS surgery is associated with a high mortality rate. Thus, to decrease both the RL and mortality rates, complicated surgery should ideally be performed by experienced surgeons in fully equipped facilities.

Early diagnosis and prediction of severity in acute pancreatitis using the urine trypsinogen-2 dipstick test: a prospective study.

AIM: To evaluate the use of the trypsinogen-2 dipstick (Actim Pancreatitis) test for early diagnosis and prediction of severity in acute pancreatitis (AP). METHODS: Ninety-two patients with AP were included in this study. The control group was 25 patients who had acute abdominal pain from non-pancreatic causes. Urine trypsinogen-2 dipstick test (UTDT) and conventional diagnostic tests were performed in all patients. Patients were divided by the Atlanta classification into two groups as having mild or severe pancreatitis. RESULTS: UTDT was positive in 87 (94.6%) of the AP patients and in two (8%) controls (P < 0.05). Positive UTDT was found in 61 (92.4%) of 66 (71.7%) patients with mild pancreatitis and in all (100%) of the 26 (28.3%) with severe pancreatitis (P > 0.05). UTDT positivity lasted longer in severe pancreatitis compared with that in mild pancreatitis (6.2 +/- 2.5 d vs 2.0 +/- 1.43 d, P < 0.05). The sensitivity, specificity, positive predictive value, negative predictive value (NPV), positive likelihood ratio (PLR) and negative likelihood ratio (NLR) of UTDT were 91%, 72%, 96.6%, 70.4%, 3.4 and 0.1, respectively. CONCLUSION: UTDT is a simple, rapid and reliable method for use on admission. It has high specificity and low NLR for early diagnosis and prediction of severity in AP. However, its relatively low NPV does not allow trypsinogen-2 dipstick test to be a stand-alone tool for diagnosis of acute pancreatitis; the use of other conventional diagnostic tools remains a requirement.

Analysis of risk factors affecting the development of seromas following breast cancer surgeries: seromas following breast cancer surgeries.

This study aimed to determine the effects of demographic, clinical, and therapeutic variables in development of seromas. The relation between development of seromas and age, preference for surgery, tumor size, existence of axillary lymph nodes and lymph nodal metastases, number of lymph nodes removed, type of surgical equipments used, drainage duration, drainage flow rate, and whether or not neoadjuvant chemotherapy was received; dead volume was reduced; or pressure garment was used in patients who received surgery due to breast cancer between 2000 and 2005 years. Mean age of 119 patients included in the study was 53.13+/-13.26 (range 26-79). Seromas were observed in 17 (14.28%) patients. In multivariate logistic regression analysis an association of postoperative seroma formation was noted with a drainage flow rate greater than 50 mL/day after 48th hours following breast surgery (p=0.007), while other variables investigated herein are not associated with development of seromas. We conclude that a drainage flow rate greater than 50 mL/day after 48th hours is a predicting factor for seroma formation in breast cancer patients. Thus, we do not recommend terminating the drainage before flow rate at 48 hours is seen and daily drainage is lower than acceptable limit.

[Thick-needle vacuum-assisted biopsy technique for inflammatory breast carcinoma diagnosis]. / Técnica de biópsia aspirativa por agulha de grosso calibre para o diagnóstico do carcinoma inflamatório da mama.

PURPOSE: Inflammatory breast carcinoma (IBC) is a rare clinicopathological cancer type with unique clinical features and a poor prognosis. In this disease, there is generally no palpable mass in the breast. IBC can be mistakenly diagnosed as mastitis and patients may receive a delayed diagnosis and treatment, since these two disorders cause similar pathological appearences on the breast. Clinical suspicion of the disease followed by histopathological observation of occluded dermal lympthatics by tumor emboli leads to definitive diagnosis of IBC. METHODS: Here, we report our experiences in diagnosing IBC using Thick-Needle Aspiration Biopsy (TNAB). RESULTS: Eight patients having clinically suspected IBC, received TNAB. IBC was definitively diagnosed upon observation in histopathological examination of occluded dermal lymphatics by tumor emboli since TNAB allowed adequate tissue sampling. CONCLUSION: In this study, we showed that IBC can be reliably diagnosed using TNAB.

OBJETIVO: O carcinoma inflamatório da mama (CIM) é um raro tipo histopatológico do câncer mamário, com características clínicas especiais e prognóstico reservado. Nesta doença, geralmente não se palpa nódulos mamários. O CIM pode equivocadamente ser diagnosticado como mastite e gerando um retardo no diagnóstico e tratamento, visto que ambas as doenças tem apresentação semelhante. A suspeita clínica da doença seguida da observação histopatológica de embolia tumoral com oclusão dos linfáticos da derme conduz ao diagnóstico definitivo de CIM. MÉTODOS: Relata-se o procedimento no diagnóstico de CIM utilizando a biópsia de aspiração por agulha de grosso calibre (BAAGC). RESULTADOS: Oito pacientes com suspeita clínica CIM foram submetidos a BAAGC. Todos os casos receberam diagnóstico definitivo de CIM após caracterização histopatológica da biópsia. BAAGC permitiu a amostragem adequada do tecido. CONCLUSÃO: O CIM pode ser diagnosticado utilizando BAAGC.

Urgent abdominal re-explorations.

BACKGROUND: Treatment of a number of complications that occur after abdominal surgeries may require that Urgent Abdominal Re-explorations (UARs), the life-saving and obligatory operations, are performed. The objectives of this study were to evaluate the reasons for performing UARs, outcomes of relaparotomies (RLs) and factors that affect mortality. METHODS: Demographic characteristics; initial diagnoses; information from and complications of the first surgery received; durations and outcomes of UAR(s) performed in patients who received early RLs because of complicated abdominal surgeries in our clinic between 01.01.2000 and 31.12.2004 were investigated retrospectively. Statistical analyses were done using the chi-square and Fisher exact tests. RESULTS: Early UAR was performed in 81 out of 4410 cases (1.8%). Average patient age was 50.46 (13-81) years with a male-to-female ratio of 60/21. Fifty one (62.96%) patients had infection, 41 (50.61%) of them had an accompanying serious disease, 24 (29.62%) of them had various tumors and 57 (70.37%) patients were operated under emergency conditions during first operation. Causes of urgent abdominal re-explorations were as follows: leakage from intestinal repair site or from anostomosis (n:34; 41.97%); hemorrhage (n:15; 18.51%); intestinal perforation (n:8; 9.87%); intraabdominal infection or abscess (n:8; 9.87%); progressive intestinal necrosis (n:7; 8.64%); stomal complications (n:5; 6.17%); and postoperative ileus (n:4; 4.93%). Two or more UARs were performed in 18 (22.22%) cases, and overall mortality was 34.97% (n:30). Interval between the first laparotomy and UAR averaged as 6.95 (1-20) days, and average hospitalization period was 27.1 (3-78) days.Mortality rate was found to be higher among the patients who received multiple UARs. The most common (55.5%) cause of mortality was sepsis/multiple organ failure (MOF). The rates for common mortality and sepsis/MOF-dependent mortality that occured following UAR were significantly higher in patients who received GIS surgery than in those who received other types of surgeries (p:0.000 and 0.010, respectively). CONCLUSION: UARs that are performed following complicated abdominal surgeries have high mortality rates. In particular, UARs have higher mortality rates following GIS surgeries or when infectious complications occur. The possibility of efficiently lowering these high rates depends on the success of the first operations that the patient had received.
