    The CT-examinations of 131 patients were analyzed after abdominal surgery. After nephrectomy, splenectomy, partial hepatectomy and pancreatectomy a displacement of the neighbouring intraabdominal and retroperitoneal organs was seen. Scar-tissue was observed containing fat, which faciltated the differential diagnosis to tumor recurrency. The changes of the roentgenmorphology were not so obvious after gastrointestinal surgery. After vascular surgery the permeability of an anastomosis or an operated artery could be demonstrated by bolus injection. (orig.).

    In spite of many advances in medicine, anesthetic technique and surgical managements, pulmonary problems are the most frequent postoperative complications, particularly after abdominal surgery. As postoperative pulmonary complications, atelectasis, pleural effusion, pneumonia, chronic bronchitis and lung abscess can be occurred. This study include evaluation of chest films of 2006 patients (927 male, 1079 female), who had been operated abdominal surgery from Jan. 1979 to June, 1980 in the Hanyang university hospital. The results were as follows: 1. 70 cases out of total 2006 cases (3.5%) developed postoperative chest complications, 51 cases (5.5%) in male, 19 cases (1.8%) in female. 2. The complication rate was increased according to the increase of age. The incidence of the postoperative complications over 40 years of age was higher than the overall average complications rate. 3. The most common postoperative pulmonary complication was pleural effusion, next pneumonia, atelectasis and pulmonary edema respectively. 4. The complication rate of the group of upper abdominal surgery is much higher than the group of lower abdominal surgery. 5. Complication rate was increased according to increase of the duration of operation. 6. There were significant correlations between the operation site and side of the complicated hemithorax

    Prolonged postoperative ileus (PPOI) is among the common complications adversely affecting postoperative outcomes. Predictors of PPOI after major abdominal surgery remain unclear, although various PPOI predictors have been reported in patients undergoing colorectal surgery. This study aimed to devise a model for stratifying the probability of PPOI in patients undergoing abdominal surgery. Between 2012 and 2013, 841 patients underwent major abdominal surgery after excluding patients who underwent less-invasive abdominal surgery, ileus-associated surgery, and emergency surgery. Postoperative managements were generally based on enhanced recovery after surgery (ERAS) program. The definition of PPOI was based on nausea, no oral diet, flatus absence, abdominal distension, and radiographic findings. A nomogram was devised by evaluating predictive factors for PPOI. Of the 841 patients, 73 (8.8%) developed PPOI. Multivariable logistic regression analysis revealed smoking history (P = 0.025), colorectal surgery (P = 0.004), and an open surgical approach (P = 0.002) to all be independent predictive factors for PPOI. A nomogram was devised by employing these three significant predictive factors. The prediction model showed relatively good discrimination performance, the concordance index of which was 0.71 (95%CI 0.66-0.77). The probability of PPOI in patients with a smoking history who underwent open colorectal surgery was calculated to be 19.6%. Colorectal surgery, open abdominal surgery, and smoking history were found to be independent predictive factors for PPOI in patients who underwent major abdominal surgery. A nomogram based on these factors was shown to be useful for identifying patients with a high probability of developing PPOI.

    Intra-abdominal pressure is the pressure's state of balance within the abdominal cavity when a patient is at rest. This pressure may vary during mechanical ventilation or spontaneous breathing. The objective was to establish the intra-abdominal pressure as a surgery predictor in patients with acute abdominal pain. From April to December, 2013, it was carried out a nested case-control study on patients with acute abdominal pain in the emergency room of a second level hospital. Thirty-seven patients fit the inclusion criteria; they all underwent surgery with a previous measurement of the intra-abdominal pressure. Based on the results of the anatomopathological study, we divided the patients into two groups: those with evidence of acute abdominal inflammatory process (n=28) (case group), and patients without evidence of acute abdominal inflammatory process (n=9) (control group). In the case group, 100 % of patients shown high intra-abdominal pressure with a p=0.01 (OR=5 [95 % CI=2.578-9.699]. In the case group, the mean intra-abdominal pressure was 11.46, and in the control group 9.2 (p=0.183). Abdominal pain requiring surgical intervention is directly related to intra-abdominal pressure>5 mmHg.

    The objective of this study was to support our hypothesis that surgical resection of abdominal metastases of melanoma, regardless of symptomatology, could provide prolonged palliation and improved survival. We performed a retrospective chart review at M.D. Anderson Cancer Center. A series of 251 melanoma patients (stages I, II, or III at registration) who developed intraabdominal metastases during follow-up were studied. Altogether, 96 patients underwent 119 laparotomies; 51 underwent endoscopic or percutaneous procedures; and 116 patients were treated medically. Surgery was associated with a median survival of 11 months, significantly longer than that with other treatment (p < 0.001). Tumor was extirpated during 37% of the first laparotomies, and in an additional 33% very good palliation was achieved with incomplete resection. Tumor extirpation was associated with 10-month symptom-free survival (SFS), significantly longer than that with any other approach (p < 0.0001). In the nonsurgically treated patients, good palliation was achieved in 8% to 17% of patients with no complete response. The median SFS after surgery was 5 months, but 23% of patients were symptom-free more than 12 months; 87 patients with minimal symptoms; and 72 severely symptomatic patients underwent surgery. Complete resection was feasible in 42% and 34%, respectively. Surgery was associated with 12 months median survival in both groups. There was a significant survival benefit from surgery in patients with gastrointestinal (GI) tract metastases in contrast to those who had non-GI metastases. For the 96 surgically treated patients, a time interval of more than 4 years between diagnosis of the primary lesion and the abdominal recurrence predicted decreased risk of death (p = 0.038). The 30-day postoperative complication and mortality rates were 19.0% and 3.3%, respectively. Complete surgical resection of melanoma metastases in the abdomen is associated with median and symptom-free survival

    Full Text Available Aim: We aimed at analysing the patients, who underwent surgical treatment in our hospital after having abdominal wounding by firearm in the war at Syria, retrospectively. Material and Method: The files of Syrian patients, who applied to Emergency Service of Harran University Medical Faculty because of gunshot wounds and had operation after being hospitalized in General Surgery Clinic due to abdominal injuries between the years of 2011 and 2014, were analysed retrospectively. Results: 175 Syrian patients, who had abdominal injuries by firearms, underwent operation in our general surgery clinic. 99.4% (n=174 of the patients were male, and 0.6% (n=1 were female. Trauma-admission to hospital times of all cases were %u2265 6 hours. 62.8% (n=110 of the patients had isolated abdominal injuries, and 37.1% (n=65 had two or more system injuries. The frequency of more than one organ injuries in abdominal region was 44.5% (n=78 and the most frequent complication was wound infection (10%. Negative laparoscopy was 2.8% (n=5, support for intensive care was 38.2% (n=67, average duration of intensive care unit stay was 5.57 days and mortality was 9.7% (n=17. Discussion: In our study, it was seen that infectious morbidity and mortality increased for the patients, who applied to our hospital because of abdominal injuries by firearm, particularly the ones with gastrointestinal perforation, if trauma-admission to hospital times were %u2265 6 hours. And this shows us that the early intervention to injuries that perforate gastrointestinal tract was an important factor for decreasing morbidity and mortality.

    Full Text Available BACKGROUND: Clinical experiences of adults who underwent surgery for esophageal atresia at birth is limited. There is some evidence that suggests considerable long-term morbidity, partly because of dysphagia, which has been reported in up to 85% of adult patients who undergo surgery for esophageal atresia. The authors hypothesized that dysphagia in this population is caused by dysmotility and/or anatomical anomalies.

    Full Text Available Minimal invasive surgery has become the standard of care for operations involving the thoracic and abdominal cavities for all ages. Laparoscopic complications can occur as well as more invasive surgical procedures and we can classify them into non-specific and specific. Our goal is to analyze the most influential available scientific literature and to expose important and recognized advices in order to reduce these complications. We examined the mechanism, risk factors, treatment and tried to outline how to prevent two major abdominal wall complications related to laparoscopy: bleeding and port site herniation .

    Objective: The aim of the present study was to compare female sexual function between women who underwent conventional abdominal or laparoscopic hysterectomy. Materials and Methods: Seventy-seven women who were scheduled to undergo hysterectomy without oophorectomy for benign gynecologic conditions were included in the study. The women were assigned to laparoscopic or open abdominal hysterectomy according to the surgeons preference. Women with endometriosis and symptomatic prolapsus were excluded. Female sexual function scores were obtained before and six months after the operation from each participant by using validated questionnaires. Results: Pre- and postoperative scores of three different quationnaires were found as comparable in the group that underwent laparoscopic hysterectomy (p>0.05). Scores were also found as comparable in the group that underwent laparotomic hysterectomy (p>0.05). Pre- and postoperative values were compared between the two groups and revealed similar results with regard to all three scores (p>0.05). Conclusion: Our data showed comparable pre- and the postoperative scores for the two different hysterectomy techniques. The two groups were also found to have similar pre- and postoperative score values. PMID:28913149

    Patients treated with antithrombotic therapy that require abdominal surgical procedures has progressively increased overtime. The management of antithrombotics during both the peri- and post- operative period is of crucial importance. The goal of this review is to present current data concerning the management of antiplatelets in patients with coronary artery disease and of anticoagulants in patients with atrial fibrillation who had to undergo abdominal surgical operations. For this purpose, incidence of major adverse cardiovascular events (MACE) and risk of antithrombotic use during surgical procedures, as well as the recommendations based on recent guidelines were reported. A thorough search of PubMed, Scopus and the Cochrane Databases was conducted to identify randomized controlled trials, observational studies, novel current reviews, and ESC and ACC/AHA guidelines on the subject. Antithrombotic use in daily clinical practice results to two different pathways: reduction of thromboembolic risk, but a simultaneous increase of bleeding risk. This may cause a therapeutic dilemma during the perioperative period. Nevertheless, careless cessation of antithrombotics can increase MACE and thromboembolic events, however, maintenance of antithrombotic therapy may increase bleeding complications. Studies and current guidelines can assist clinicians in making decisions for the treatment of patients that undergo abdominal surgical operations while on antithrombotic therapy. Aspirin should not be stopped perioperatively in the majority of surgical operations. Determining whether to discontinue the use of anticoagulants before surgery depends on the surgical procedure. In surgical operations with a low risk for bleeding, oral anticoagulants should not be discontinued. Bridging therapy should only be considered in patients with a high risk of thromboembolism. Finally, patients with an intermediate risk for thromboembolism, management should be individualized according to patient

    1984-01-01

    During a 36-month period, 89 patients have undergone percutaneous endoscopic gastrostomy without mortality. Of these patients, 25 (13 infants and children, 12 adults) had prior abdominal procedures that increased their risk for the endoscopic procedure. With two exceptions, all gastrostomies were performed utilizing local anesthesia. There was one major complication, a gastrocolic fistula, which was successfully managed by repeating the endoscopic gastrostomy procedure at a location more cephalad in the stomach. Twenty-two of the gastrostomies were placed for feeding purposes and all of these patients were able to leave the hospital with alimentation accomplished via the tube. Three of the endoscopically placed gastrostomies were for gastrointestinal tract decompression. A total of 255 patient months have been accumulated in these patients with the endoscopically placed gastrostomy in situ. The technique can be safely performed in patients with prior abdominal surgery and in the majority of cases is the technique of choice for establishing a tube gastrostomy. PMID:6428334

    To determine the effectiveness of using multidetector computed tomography (MDCT) data in preoperative planning of robot-assisted surgery. Fourteen patients indicated for surgery underwent MDCT using 64 and 256-slice MDCT. Before the examination, a specially constructed navigation net was placed on the patient's anterior abdominal wall. Processing of MDCT data was performed on a Brilliance Workspace 4 (Philips). Virtual vectors that imitate robotic and assistant ports were placed on the anterior abdominal wall of the 3D model of the patient, considering the individual anatomy of the patient and the technical capabilities of robotic arms. Sites for location of the ports were directed by projection on the roentgen-positive tags of the navigation net. There were no complications observed during surgery or in the post-operative period. We were able to reduce robotic arm interference during surgery. The surgical area was optimal for robotic and assistant manipulators without any need for reinstallation of the trocars. This method allows modeling of the main steps in robot-assisted intervention, optimizing operation of the manipulator and lowering the risk of injuries to internal organs.

    Full Text Available Background. S100B protein, previously proposed as a consolidated marker of brain damage in congenital heart disease (CHD newborns who underwent cardiac surgery and cardiopulmonary bypass (CPB, has been progressively abandoned due to S100B CNS extra-source such as adipose tissue. The present study investigated CHD newborns, if adipose tissue contributes significantly to S100B serum levels. Methods. We conducted a prospective study in 26 CHD infants, without preexisting neurological disorders, who underwent cardiac surgery and CPB in whom blood samples for S100B and adiponectin (ADN measurement were drawn at five perioperative time-points. Results. S100B showed a significant increase from hospital admission up to 24 h after procedure reaching its maximum peak (P0.05 have been found all along perioperative monitoring. ADN/S100B ratio pattern was identical to S100B alone with the higher peak at the end of CPB and remained higher up to 24 h from surgery. Conclusions. The present study provides evidence that, in CHD infants, S100B protein is not affected by an extra-source adipose tissue release as suggested by no changes in circulating ADN concentrations.

    Compare the visual acuity of patients who underwent cataract surgery by phacoemulsification with IOL AcrySof(®) toric implantation versus AcrySof(®) IQ and evaluate the reduction of cylindrical diopters (CD) in the postoperative period. Analytical and retrospective study of 149 eyes with 1 or more diopters of regular symmetrical keratometric astigmatism, which underwent cataract surgery by phacoemulsification. The eyes were divided into two groups: the toric group with 85 eyes and the non-toric group with 64 eyes. In the pre-operative phase, topographic data and refraction of each eye to be operated were assessed. In the postoperative phase, refraction and visual acuity with and without correction were measured. The preoperative topographic astigmatism ranged from 1.00 to 5.6 DC in both groups. Average reduction of 1.37 CD (p<0.001) and 0.16 CD (p=0.057) was obtained for the toric and non-toric group when compared to the refractive astigmatism, respectively. Considering visual acuity without correction (NCVA), the toric group presented 44 eyes (51.7%) with NCVA of 0 logMAR (20/20) or 0.1 logMAR (20/25) and the toric group presented 7 eyes (10.93%) with these same NCVA values. The results show that patients with a significant keratometric astigmatism presented visual benefits with the toric IOL implantation. The reduction of the use of optical aids may be obtained provided aberrations of the human eye are corrected more accurately. Currently, phacoemulsification surgery has been used not only for functional improvement, but also as a refraction procedure.

    Postoperative pulmonary complications (PPCs) after major abdominal surgery are common and associated with significant morbidity and high cost of care. The objective of this study was to identify the risk factors for PPCs after major abdominal surgery. The American College of Surgeons' National Surgical Quality Improvement Program database from 2005-2012 was queried for patients who underwent major abdominal surgery (esophagectomy, gastrectomy, pacnreatectomy, enterectomy, hepatectomy, colectomy, and proctectomy). Predictors of PPCs were identified using multivariate logistic regression. Of 165,196 patients who underwent major abdominal surgery 9595 (5.8%) suffered PPCs (pneumonia 3.2%, prolonged ventilator support ≥48 h 3.0%, and unplanned intubation 2.8%). On multivariate analysis, significant predictors of overall and individual PPCs include esophagectomy, advanced American Society of Anesthesiology Classification System, dependent functional status, prolonged operative time, age ≥80 y, severe chronic obstructive pulmonary disease, preoperative shock, ascites, and smoking. Obesity was not a risk factor. Female gender was overall protective for PPCs. PPCs after abdominal procedures are associated with a number of clinical variables. Esophageal operations and American Society of Anesthesiology Classification System were the strongest predictors. These results provide a framework for identifying patients at risk for developing pulmonary complications after major abdominal surgery. Copyright © 2015 Elsevier Inc. All rights reserved.

    The authors analyzed the data of 281 cases of iatrogenes of manipulator character in abdominal surgery in order to investigate the circumstances and character of origin. There were 187 cases of operative confirmation and 84 cases of unintentional intraoperative retained foreign bodies. It was detected, that primary planned intervention of higher category of complexity should be related to the high risk group of the development of the operative confirmation. Retained foreign bodies with soft fabric base were diagnosed in early postoperative period as the result of the beginning of postoperative complications. The retained foreign bodies with tough backer material as a rule didn't cause the complications in early postoperative period. They were diagnosed in long-term postoperative period in majority of cases.

    To identify the risk factors for morbidity and mortality after elective and emergency abdominal surgeries in maintenance hemodialysis patients. We retrospectively evaluated the medical records of 63 hemodialysis patients who underwent elective (group 1) and 24 who underwent emergency (group 2) abdominal surgeries, and classified them according to the presence/absence of postoperative complications. The clinical, laboratory and procedure-related data were obtained and compared between the groups. Group 2 had significantly higher morbidity and mortality rates than group 1 (58.3 and 16.6 % vs. 33.3 and 16.6 %, respectively, P high BUN levels in the elective surgery patients and hypoproteinemia, hypoalbuminemia, a longer operation and older age in patients undergoing emergency surgery. Perioperative blood transfusion was also associated with a high complication rate in the emergency surgery group.

    Damage control surgery (DCS) was a major paradigm change in the management of critically ill trauma patients and has gradually expanded in the general surgery arena, but data in this setting are still scarce. The study aim was to evaluate outcomes of DCS in patients with general surgery emergencies. Between 2005 and 2015, 164 patients (104 men, age 66) underwent DCS for non-traumatic abdominal emergencies. The decision to perform DCS was triggered by the presence of at least one trauma DCS criterion: hypotension (5 RBC) transfusion. Statistical tests were performed to identify risk factors for operative mortality. Observed outcomes were compared to those predicted by commonly employed scores (APACHE II, POSSUM, P-POSSUM, SAPS II). DCS was performed for acute mesenteric ischemia (n = 68), peritonitis (n = 44), pancreatitis (n = 28), bleeding (n = 14) and other (n = 10). Abdominal compartment syndrome was associated in 52 patients (32%). Seventy-four (45%) patients died and 150 patients (91%) experienced complications. On multivariate analysis, age (p = 0.018) and INR ≥ 1.7 (p = 0.001) were independent predictors of mortality. Mortality was 24% (13/55), 48% (22/46) and 62% (39/63) in patients with one, two and ≥3 DCS criteria, respectively. Comparison of observed and score-predicted mortality suggested DCS use resulted in significant survival benefit of the whole cohort and of patients with pancreatitis and postoperative peritonitis. DCS can be lifesaving in critically ill patients with general surgery emergencies. Patients with peritonitis and acute pancreatitis are those who benefit most of the DCS approach.

    Roux-en-Y gastric bypass (RYGB) is a highly effective treatment for obesity and results in long-term weight loss and resolution of co-morbidities. However, weight regain may occur as soon as 1-2 years after surgery. This retrospective study aimed to investigate the prevalence of weight regain and possible preoperative predictors of this phenomenon after RYGB. An academic medical center in the United States. A total of 1426 obese patients (15.8% male) who underwent RYGB during January 2000 to 2012 and had at least a 2-year follow-up were reviewed. We included only patients who were initially successful, having achieved at least 50% excess weight loss at 1 year postoperatively. Patients were then categorized into either the weight regain group (WR) or sustained weight loss (SWL) group based upon whether they gained≥15% of their 1-year postoperative weight. Weight regain was observed in 244 patients (17.1%). Preoperative body mass index was similar between groups. Body mass index was significantly higher and percent excess weight loss was significantly lower in the WR group (Pweight regain was 19.5±9.3 kg and-.8±8.5 in the WR and SWL groups, respectively (Pweight loss. Moreover, a longer duration after RYGB was associated with weight regain. Multivariate analysis revealed that younger age was a significant predictor of weight regain even after adjusting for time since RYGB. The present study confirmed that a longer interval after RYGB was associated with weight regain. Younger age was a significant predictor of weight regain even after adjusting for time since RYGB. The findings of this study underscore the complexity of the mechanisms underlying weight loss and regain after RYGB. Future prospective studies are needed to further explore the prevalence, predictors, and mechanisms of weight regain after RYGB. Copyright © 2016 American Society for Bariatric Surgery.

    Anterior longitudinal ligament perforation and abdominal vascular injury is one of the most critical complications that may develop during lumbar disc surgery. The vascular injury-related symptoms that warns the surgeon may be late to appear; they usually turn out to be mortal. The hypotension during the operation, tachycardia and pulsatile unstoppable hemorrhage observed in the disc space are the major findings. Urgent detection of this complication and the repair of the vascular injury prevent the case from turning out to be fatal. In the present study, three patients who underwent surgical treatment of abdominal vascular injuries that had developed during lumbar disc surgery, were presented.

    The impact of previous abdominal surgeries on the need for conversion to open surgery and on short-term outcomes during/after laparoscopic colectomy was retrospectively investigated. This retrospective cohort study was conducted from December 1996 through December 2009. This study was conducted at Osaka Medical College Hospital. A total of 1701 consecutive patients who had undergone laparoscopic resection of the colon and rectum were classified as not having previous abdominal surgery (n = 1121) or as having previous abdominal surgery (n = 580). Short-term outcomes were recorded, and risk factors for conversion to open surgery were analyzed. There were no significant differences in operative time, blood loss, number of lymph nodes removed, or conversion rate between the groups. The rate of inadvertent enterotomy was significantly higher in the previous abdominal surgery group than in the not having previous abdominal surgery group (0.9% versus 0.1%; p = 0.03), and the postoperative recovery time was significantly longer in the previous abdominal surgery group than in the not having previous abdominal surgery group. Ileus was more frequent in the previous abdominal surgery group than in the not having previous abdominal surgery group (3.8% versus 2.1%; p = 0.04). Significant risk factors for conversion to open surgery were T stage ≥3 (OR, 2.81; 95% CI, 1.89-3.75), median incision (OR, 4.34; 95% CI, 1.23-9.41), upper median incision (OR, 2.78; 95% CI, 1.29-5.42), lower median incision (OR, 1.82; 95% CI, 1.09-3.12), and transverse colectomy (OR, 1.76; 95% CI, 1.29-2.41). The incidence of successfully completed laparoscopic colectomy after previous abdominal surgery remains high, and the short-term outcomes are acceptable.

    Hiroshi Ueda

    Full Text Available Abstract Background and objectives: The number of laparoscopic surgeries performed is increasing every year and in most cases the pneumoperitoneum method is used. One alternative is the abdominal wall lifting method and this study was undertaken to evaluate changes of functional residual capacity during the abdominal wall lift procedure. Methods: From January to April 2013, 20 patients underwent laparoscopic cholecystectomy at a single institution. All patients were anesthetized using propofol, remifentanil and rocuronium. FRC was measured automatically by Engstrom Carestation before the abdominal wall lift and again 15 minutes after the start of the procedure. Results: After abdominal wall lift, there was a significant increase in functional residual capacity values (before abdominal wall lift 1.48 × 103 mL, after abdominal wall lift 1.64 × 103 mL (p < 0.0001. No complications such as desaturation were observed in any patient during this study. Conclusions: Laparoscopic surgery with abdominal wall lift may be appropriate for patients who have risk factors such as obesity and respiratory disease.

    Postoperative complications have been identified as an important and potentially preventable cause of increased hospital costs. While older adults are at increased risk of experiencing complications and other adverse events, very little research has specifically examined how these events impact inpatient costs. We sought to examine the association between postoperative complications, hospital mortality and loss of independence and direct inpatient health care costs in patients 70 years or older who underwent nonelective abdominal surgery. We prospectively enrolled consecutive patients 70 years or older who underwent nonelective abdominal surgery between July 1, 2011, and Sept. 30, 2012. Detailed patient-level data were collected regarding demographics, diagnosis, treatment and outcomes. Patient-level resource tracking was used to calculate direct hospital costs (2012 $CDN). We examined the association between complications, hospital mortality and loss of independence cost using multiple linear regression. During the study period 212 patients underwent surgery. Overall, 51.9% of patients experienced a nonfatal complication (32.5% minor and 19.4% major), 6.6% died in hospital and 22.6% experienced a loss of independence. On multivariate analysis nonfatal complications (p abdominal surgery in older adults and accounted for 44% of overall costs. This represents a substantial opportunity for better patient outcomes and cost savings with quality improvement strategies tailored to the needs of this high-risk surgical population.

    Due to the recent advances in radiological diagnostic technology, the role of video-assisted thoracoscopic surgery in thoracic disease has expanded, surgical indication extended to the elderly patients. Cancer patients receiving surgery, radiation therapy and/or chemotherapy may encounter complications in conjunction with the oral cavity such as aspiration pneumonia, surgical site infection and various type of infection. Recently, it is recognized that oral health care management is effective to prevent the postoperative infectious complications, especially pneumonia. Therefore, oral management should be scheduled before start of therapy to prevent these complications as supportive therapy of the cancer treatment. In this background, perioperative oral function management is highlighted in the remuneration for dental treatment revision of 2012,and the importance of oral care has been recognized in generally. In this manuscript, we introduce the several opinions and evidence based on the recent previous reports about the perioperative oral health care and management on thoracic surgery.

    We clinically investigated 34 patients with obstructive colorectal cancer who underwent placement of a colonic stent as a bridge to surgery(BTS), focusing on endoscopic findings after stent placement.Twenty -nine patients(85.3%)underwent colonoscopy after stent placement, and the entire large intestine could be observed in 28(96.6%).Coexisting lesions were observed in 22(78.6%)of these 28 patients.The lesions comprised adenomatous polyps in 17 patients(60.7%), synchronous colon cancers in 5 patients(17.9%), and obstructive colitis in 3 patients(10.7%), with some overlapping cases.All patients with multiple cancers underwent one-stage surgery, and all lesions were excised at the same time.Colonoscopy after colonic stent placement is important for preoperative diagnosis of coexisting lesions and planning the extent of resection. These considerations support the utility of colonic stenting for BTS.

  2. Respiratory muscle activity and respiratory obstruction after abdominal surgery.

    2006-04-01

    Respiratory movements in patients after abdominal surgery are frequently abnormal, with associated disturbances in the pattern of inspiratory pressure generation. The reasons for these abnormalities are not clear and have been attributed to impaired action of the diaphragm. However, an alternative is that partial airway obstruction could trigger reflex activation of the inspiratory ribcage muscles, which would cause a similar pattern of inspiratory pressure change. Direct measurement of electrical activity can indicate if reflex activation of inspiratory muscles occurs when partial airway obstruction is present. In an open study, we implanted electrodes to measure the EMG of scalene, intercostal and external oblique abdominal muscles in patients after lower abdominal surgery. Analgesia was with morphine i.v. by patient control. We used nasal cannulae to measure nasal airflow and compared EMG activity when airway obstruction was present with activity when breathing was not obstructed. The pattern of activity of the different muscles was distinct. Intercostal activity reached a maximum during inspiration, before the scalene muscles, whereas scalene activity increased in phase with increasing lung volume. Abdominal muscle activity commenced when expiratory flow had ceased and continued until the next inspiration. In all three muscle groups, partial airway obstruction did not alter muscle activity. Partial airway obstruction does not activate inspiratory ribcage muscles, in patients receiving morphine for postoperative analgesia after lower abdominal surgery. Changes in respiratory pressures and abnormalities of chest wall movement described in previous studies cannot be attributed to reflex responses and probably result from increased airway resistance and abdominal muscle action.

    Abdominal emergencies can also be operated on through the laparoscopic approach: the approach can be diagnostic laparoscopy, surgery assisted by laparoscopy or laparotomy directed according to the findings of the laparoscopy. The general contraindications refer above all to the state of haemodynamic instability of the patient and to seriously ill patients (ASA IV). In the absence of any specific counter-indications for the specific laparoscopic procedure to be carried out, many abdominal diseases requiring emergency surgery can be performed with the laparoscopic approach. The most frequent indications are appendicitis, acute colecistitis, gastroduodenal perforation, occlusion of the small intestine, and some abdominal traumas. With a correct selection of patients and the appropriate experience of the surgeon, the results are excellent and better than open surgery (less infection of the wound, complications, hospital stay and postoperative pain). A detailed explanation is given of the basic aspects of the surgical technique in the most frequent procedures of emergency laparoscopy.

    Metatarsal head resection is a common and standardized treatment used as part of the surgical routine for metatarsal head osteomyelitis. The aim of this study was to define the influence of the amount of the metatarsal resection on the development of reulceration or ulcer recurrence in patients who suffered from plantar foot ulcer and underwent metatarsal surgery. We conducted a prospective study in 35 patients who underwent metatarsal head resection surgery to treat diabetic foot osteomyelitis with no prior history of foot surgeries, and these patients were included in a prospective follow-up over the course of at least 6 months in order to record reulceration or ulcer recurrences. Anteroposterior plain X-rays were taken before and after surgery. We also measured the portion of the metatarsal head that was removed and classified the patients according the resection rate of metatarsal (RRM) in first and second quartiles. We found statistical differences between the median RRM in patients who had an ulcer recurrence and patients without recurrences (21.48 ± 3.10% vs 28.12 ± 10.8%; P = .016). Seventeen (56.7%) patients were classified in the first quartile of RRM, which had an association with ulcer recurrence (P = .032; odds ratio = 1.41; 95% confidence interval = 1.04-1.92). RRM of less than 25% is associated with the development of a recurrence after surgery in the midterm follow-up, and therefore, planning before surgery is undertaken should be considered to avoid postsurgical complications. © The Author(s) 2015.

    There is overlap between general, abdominal and vascular surgery on one hand and plastic surgery on the other hand, e.g., in hernia surgery, in particular, recurrent hernia, reconstruction of the abdominal wall or defect closure after abdominal or vascular surgery. Bariatric operations involve both special fields too. Plastic surgeons sometimes use skin and muscle compartments of the abdominal wall for reconstruction at other regions of the body. This article aims to i) give an overview about functional, anatomic and clinical aspects as well as the potential of surgical interventions in plastic surgery. General/abdominal/vascular surgeons can benefit from this in their surgical planning and competent execution of their own surgical interventions with limited morbidity/lethality and an optimal, in particular, functional as well as aesthetic outcome, ii) support the interdisciplinary work of general/abdominal/vascular and plastic surgery, and iii) provide a better understanding of plastic surgery and its profile of surgical interventions and options.

    To determine the effects of beating heart surgery on patients undergoing simultaneous coronary artery bypass grafting and abdominal aortic surgery, we performed such surgery on 20 patients (mean age, 64.55 ± 7.96 SD years). Abdominal aortic disease was defined as an abdominal aortic aneurysm larger than 5 cm in diameter or as end-stage aortic occlusive disease. Hemodynamic measurements, inotropic requirements, and incidence of perioperative myocardial infarction and arrhythmias were recorded, as were subsystem clinical outcomes, length of intensive care unit and hospital stays, blood loss, and transfusion requirements. There was no incidence of death, perioperative myocardial infarction, stroke, or acute renal failure. The mean number of grafts per patient was 1.95 ± 0.69. Only 4 minor postoperative complications were observed: three patients (15%) had evidence of supraventricular tachyarrhythmias, and 1 patient (5%) had chest infection that required a longer-than-average intubation period. Six patients (30%) required minimal-to-moderate inotropic support. The mean blood loss was 673 ± 246.8 mL and transfusion requirements were low. The mean intensive care unit and hospital lengths of stay were 2.12 ± 0.33 days and 7.08 ± 1.44 days, respectively. Clinical follow-up (mean, 10 months) showed all patients to be in New York Heart Association functional class I or II with no late cardiac or abdominal events. We conclude that simultaneous coronary artery bypass grafting and abdominal aortic surgery on the beating heart is safe and effective, and has a low perioperative clinical morbidity rate. To our knowledge, ours is the 1st report on this procedure. Larger studies with longer follow-up are needed. PMID:10830623

    Abdurrahim Çolak

    Full Text Available Abstract Objetive: Saline-irrigated radiofrequency ablation, which has been widely used for surgical treatment of atrial fibrillation in recent years, is 80-90% successful in achieving sinus rhythm. In our study, our surgical experience and mid-term results in patients who underwent mitral valve surgery and left atrial radiofrequency ablation were analyzed. Methods: Forty patients (15 males, 25 females; mean age 52.05±9.9 years; range 32-74 underwent surgery for atrial fibrillation associated with mitral valvular disease. All patients manifested atrial fibrillation, which started at least six months before the surgical intervention. The majority of patients (36 patients, 90% were in NYHA class III; 34 (85% patients had rheumatic heart disease. In addition to mitral valve surgery and radiofrequency ablation, coronary artery bypass, DeVega tricuspid annuloplasty, left ventricular aneurysm repair, and left atrial thrombus excision were performed. Following discharge from the hospital, patients' follow-up was performed as outpatient clinic examinations and the average follow-up period of patients was 18±3 months. Results: While the incidence of sinus rhythm was 85.3% on the first postoperative day, it was 80% during discharge and 71% in the 1st year follow-up examination. Conclusion: Radiofrequency ablation is an effective method when it is performed by appropriate surgical technique.

    Full Text Available Tae Hoon Kim, Jae Seung Lee, Sei Won Lee, Yeon-Mok Oh Department of Pulmonary and Critical Care Medicine, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Korea Abstract: Postoperative pulmonary complications (PPCs are one of the most important causes of postoperative morbidity and mortality after abdominal surgery. Although chronic obstructive pulmonary disease (COPD has been considered a risk factor for PPCs, it remains unclear whether mild-to-moderate COPD is a risk factor. This retrospective cohort study included 387 subjects who underwent abdominal surgery with general anesthesia in a tertiary referral hospital. PPCs included pneumonia, pulmonary edema, pulmonary thromboembolism, atelectasis, and acute exacerbation of COPD. Among the 387 subjects, PPCs developed in 14 (12.0% of 117 patients with mild-to-moderate COPD and in 13 (15.1% of 86 control patients. Multiple logistic regression analysis revealed that mild-to-moderate COPD was not a significant risk factor for PPCs (odds ratio [OR] =0.79; 95% confidence interval [CI] =0.31–2.03; P=0.628. However, previous hospitalization for respiratory problems (OR =4.20; 95% CI =1.52–11.59, emergency surgery (OR =3.93; 95% CI =1.75–8.82, increased amount of red blood cell (RBC transfusion (OR =1.09; 95% CI =1.05–1.14 for one pack increase of RBC transfusion, and laparoscopic surgery (OR =0.41; 95% CI =0.18–0.93 were independent predictors of PPCs. These findings suggested that mild-to-moderate COPD may not be a significant risk factor for PPCs after abdominal surgery.Keywords: postoperative pulmonary complications, spirometry, risk factor, abdominal surgery, postoperative complications, postoperative care

    This study aims to estimate the value of embryonal natural orifice transluminal endoscopic surgery (ENOTES) as a treatment for severe acute pancreatitis (SAP) complicated by abdominal compartment syndrome (ACS). The patients who were randomized into ENOTES group and surgery group underwent ENOTES and laparotomy, respectively. The Efficacy and complications of these two treatments were compared. Enterocinesia was observed earlier in patients of ENOTES group than that of surgery group. Acute Physiology and Chronic Health Evaluation II (APACHE II) score of patients in ENOTES group was superior to that of surgery group on the 1st, 3rd and 5th day after treatment (P complications and mortality were observed between two groups (P complications.

  20. [Nononcologic abdominal surgery in the elderly].

    Due to rising life expectancy of the population, the proportion of elderly patients requiring surgery is rising as well. Present aspects of selected, typical, nononcologic diseases of elderly people are discussed. The key to success in their treatment is not to consider primarily the patient's calendrical age but to assess the individual profile of risk factors on the basis of comorbidities. The kind, extent, and timing of an operation has to be based on this assessment. For the treatment of acute diseases (e.g., complicated ulcera, cholecystitis, appendicitis, mesenteric ischemia, and diverticulitis), a rapid and efficacious diagnostic algorithm is essential that takes into account the reduced functional reserve of old people. Constructive interdisciplinary cooperation and minimally invasive techniques play dominant roles in both diagnosis and therapy. Given these prerequisites, there is no reason to withhold surgical intervention from elderly patients.

    Intra-abdominal drains are frequently used after pancreatic surgery whereas their benefit in other gastrointestinal operations has been questioned. The objective of this meta-analysis was to compare abdominal drainage with no drainage after pancreatic surgery. PubMed, the Cochrane Library and Web of Science electronic databases were searched systematically to identify RCTs comparing abdominal drainage with no drainage after pancreatic surgery. Two independent reviewers critically appraised the studies and extracted data. Meta-analyses were performed using a random-effects model. Odds ratios (ORs) were calculated to aggregate dichotomous outcomes, and weighted mean differences for continuous outcomes. Summary effect measures were presented together with their 95 per cent confidence intervals. Some 711 patients from three RCTs were included. The 30-day mortality rate was 2·0 per cent in the drain group versus 3·4 per cent after no drainage (OR 0·68, 95 per cent c.i. 0·26 to 1·79; P = 0·43). The morbidity rate was 65·6 per cent in the drain group and 62·0 per cent in the no-drain group (OR 1·17, 0·86 to 1·60; P = 0·31). Clinically relevant pancreatic fistulas were seen in 11·5 per cent of patients in the drain group and 9·5 per cent in the no-drain group. Reinterventions, intra-abdominal abscesses and duration of hospital stay also showed no significant difference between the two groups. Pancreatic resection with, or without abdominal drainage results in similar rates of mortality, morbidity and reintervention. © 2017 BJS Society Ltd Published by John Wiley & Sons Ltd.

  2. Intra-abdominal pressure and abdominal compartment syndrome in acute general surgery.

    LENUS (Irish Health Repository)

    Sugrue, Michael

    2012-01-31

    BACKGROUND: Intra-abdominal pressure (IAP) is a harbinger of intra-abdominal mischief, and its measurement is cheap, simple to perform, and reproducible. Intra-abdominal hypertension (IAH), especially grades 3 and 4 (IAP > 18 mmHg), occurs in over a third of patients and is associated with an increase in intra-abdominal sepsis, bleeding, renal failure, and death. PATIENTS AND METHODS: Increased IAP reading may provide an objective bedside stimulus for surgeons to expedite diagnostic and therapeutic work-up of critically ill patients. One of the greatest challenges surgeons and intensivists face worldwide is lack of recognition of the known association between IAH, ACS, and intra-abdominal sepsis. This lack of awareness of IAH and its progression to ACS may delay timely intervention and contribute to excessive patient resuscitation. CONCLUSIONS: All patients entering the intensive care unit (ICU) after emergency general surgery or massive fluid resuscitation should have an IAP measurement performed every 6 h. Each ICU should have guidelines relating to techniques of IAP measurement and an algorithm for management of IAH.

    To evaluate the influence of prior abdominal surgery on surgical outcomes of robot-assisted radical prostatectomy in an early single center experience in Japan. We reviewed medical records of patients with localized prostate cancer who underwent robot-assisted radical prostatectomy from October 2010 to September 2013 at Tottori University Faculty of Medicine, Yonago, Tottori, Japan. Patients with prior abdominal surgery were compared with those with no prior surgery with respect to total operative time, port-insertion time, console time, positive surgical margin and perioperative complication rate. Furthermore, the number of patients requiring minimal adhesion lysis was compared between the two groups. Of 150 patients who underwent robot-assisted radical prostatectomy, 94 (63%) had no prior abdominal surgery, whereas 56 patients (37%) did. The mean total operative time was 329 and 333 min (P = 0.340), mean port insertion time was 40 and 34.5 min (P = 0.003), mean console time was 255 and 238 min (P = 0.145), a positive surgical margin was observed in 17.9% and 17.0% patients (P = 0.896), and the incidence of perioperative complications was 25% and 23.4% (P = 0.825), respectively, in those with and without prior abdominal surgery. In the prior abdominal surgery group, 48 patients (80.4%) required adhesion lysis at the time of trocar placement or while operating the robotic console. Robot-assisted radical prostatectomy appears to be a safe approach for patients with prior abdominal surgery without increasing total operative time, robotic console time, positive surgical margin or the incidence of perioperative complications. © 2014 The Japanese Urological Association.

    Clinical studies have shown that sevoflurane is cardio-protective in cardiac surgery patients, but this effect is doubtful in general surgery patients. This study has researched the influence of sevoflurane on the perioperative cardiac function and the incidence of cardiac ischaemic events in abdominal surgical patients. Out of 80 patients scheduled for elective colorectal surgery, 42 received balanced sevoflurane-fentanyl anaesthesia, while 38 received intravenous midazolam-fentanyl anaesthesia. The cardiac index (CI) and cardiac function index (CFI) were measured by the PiCCO device, and Troponin I levels were measured at the beginning of surgery, as well as 4, 12 and 24 h afterwards. BNP was measured at the beginning of surgery, and 24 h afterwards. The data analysis was conducted using the Mann-Whitney nonparametric test, with statistical significance set at p abdominal surgical patients. Further research on the preconditioning effect of volatile anaesthetics in general surgical population should be concentrated on the population of patients with a high perioperative cardiac risk.

    Full Text Available Citrus aurantium is rich in flavonoids, which may prevent osteosarcoma progression, but its related molecular mechanism remains unclear. Flavonoids were extracted from C. aurantium and purified by reparative HPLC. Each fraction was identified by using electrospray ionisation mass spectrometry (ESI-MS. Three main components (naringin, naringenin, and hesperetin were isolated from C. aurantium. Naringenin inhibited the growth of MG-63 cells, whereas naringin and hesperetin had no inhibitory function on cell growth. ROS production was increased in naringin- and hesperetin-treated groups after one day of culture while the level was always lowest in the naringenin-treated group after three days of culture. 95 osteosarcoma patients who underwent surgery were assigned into two groups: naringenin group (NG, received 20 mg naringenin daily, n=47 and control group (CG, received 20 mg placebo daily, n=48. After an average of two-year follow-up, osteosarcoma volumes were smaller in the NG group than in the CG group (P>0.01. The rate of osteosarcoma recurrence was also lower in the NG group than in CG group. ROS levels were lower in the NG group than in the CG group. Thus, naringenin from Citrus aurantium inhibits osteosarcoma progression and local recurrence in the patients who underwent osteosarcoma surgery by improving antioxidant capability.

    Full Text Available Objective: To explore the effect of advanced blood pressure control with nifedipine delayedrelease tablets on the blood pressure in patients underwent nasal endoscope surgery and its feasibility. Methods: A total of 80 patients who were admitted in ENT department from June, 2012 to June, 2015 for nasal endoscope surgery were included in the study and randomized into the observation group and the control group with 40 cases in each group. The patients in the observation group were given nifedipine delayed-release tablets for advanced blood pressure control before operation, and were given routine blood pressure control during operation; while the patients in the control group were only given blood pressure control during operation. The changes of blood pressure, mean central arterial pressure, and heart rate before anesthesia (T0, after intubation (T1, during operation (T2, extubation when waking (T3, 30 min after extubation (T4, and 3 h after back to wards (T5 in the two groups were compared. The intraoperative situation and the surgical field quality in the two groups were compared. Results: SBP, DBP, and MAP levels at T1-5 in the two groups were significantly lower than those at T0. SBP, DBP, and MAP levels at T2 were significantly lower than those at other timing points, and were gradually recovered after operation, but were significantly lower than those at T0. The effect taking time of blood pressure reducing, intraoperative nitroglycerin dosage, and postoperative wound surface exudation amount in the observation group were significantly less than those in the control group. The surgical field quality scores in the observation group were significantly superior to those in the control group. Conclusions: Advanced blood pressure control with nifedipine delayed-release tablets can stabilize the blood pressure during the perioperative period in patients underwent nasal endoscope surgery, and enhance the surgical field qualities.

    This study compared perioperative restrictive fluid therapy to liberal (conventional) fluid therapy in patients undergoing major abdominal surgery and investigated the rate of post-operative morbidity (complication rates), recovery (time to flatus), and the length of hospital stay. The Medline, PubMed, Cochrane, and EMBASE databases were searched until June 18, 2015. Randomized controlled trials, two-arm prospective studies, and retrospective studies were included in our analyses. A sensitivity analysis, publication bias assessment, and quality assessment were performed. The effects of the two therapies were similar in the subgroup analysis of patients who underwent hepato-gastroenterological surgery (P = 0.287). However, in a subgroup of patients who underwent vascular abdominal surgery, the restricted fluid treatment regimen was associated with a lower risk of complications in comparison with the conventional regimen (pooled OR = 0.12, 95 % CI 0.03-0.47, P = 0.002). There was no difference between the two regimens with respect to the incidence of cardiopulmonary complications (P = 0.733). However, the patients who received the restricted fluid treatment regimen had a shorter time to flatus (P = 0.031) and a shorter hospital stay (P = 0.033) than the patients who received the conventional regimen. Restrictive fluid therapy and liberal conventional therapy were associated with similar rates of overall and cardiopulmonary complications; however, restrictive fluid therapy was associated with a more rapid recovery and a shorter length of hospital stay.

    The purpose of this paper is to demonstrate the effect of the transfusion of blood received 1500 rad exposure upon the immune response in 14 patients underwent various type of cardiac surgery. 13 patients received known amounts banked blood and irradiated fresh blood, while one patient received a lot of amounts of banked and irradiated and non-irradiated fresh blood. The authors studied the numbers of lymphocytes as well as lymphocyte subsets such as pan-T cells, B cells, helper/inducer T cells (T H/I ), cytotoxic/supressor T cells (T C/S ), active T cells, natural killer (NK) cells and NK cell activity during two weeks after surgeries. In all 14 patients, pan-T lymphocytes decreased markedly in a few days after surgeries, but increased to higher levels on the eight postoperative day than the levels preoperatively. T H/I and T C/S lymphocytes changed on the similar pattern as pan-T lymphocytes. Active T and B cells did not change significantly in two weeks. The number and activity of NK cells gave the lowest levels on the second postoperative day and did not recovery to the preoperative levels in two weeks. One patient received non-irradiated fresh blood showed the similar immune response as other 13 patients, while he gave the lower levels than others did. This patient died of graft-versus-host disease (GVHD)-like syndrome on the 36th postoperative day. It may be thought that the transfusion of irradiated blood would prevent the host from GVHD and gave the better effects on the immune response than that of non-irradiated blood following open-heart surgeries.

    To determine the value of a raw data-based metal artifact reduction (SEMAR) algorithm for image quality improvement in abdominal CT for patients with small metal implants. Fifty-eight patients with small metal implants (3-15 mm in size) who underwent treatment for hepatocellular carcinoma were imaged with CT. CT data were reconstructed by filtered back projection with and without SEMAR algorithm in axial and coronal planes. To evaluate metal artefact reduction, mean CT number (HU and SD) and artefact index (AI) values within the liver were calculated. Two readers independently evaluated image quality of the liver and pancreas and visualization of vasculature using a 5-point visual score. HU and AI values and image quality on images with and without SEMAR were compared using the paired Student's t-test and Wilcoxon signed rank test. Interobserver agreement was evaluated using linear-weighted κ test. Mean HU and AI on images with SEMAR was significantly lower than those without SEMAR (P < 0.0001). Liver and pancreas image qualities and visualizations of vasculature were significantly improved on CT with SEMAR (P < 0.0001) with substantial or almost perfect agreement (0.62 ≤ κ ≤ 0.83). SEMAR can improve image quality in abdominal CT in patients with small metal implants by reducing metallic artefacts. (orig.)

    OBJECTIVE: Surgery launches a systemic inflammatory reaction that reaches the brain and associates with immune activation and cognitive decline. Although preclinical studies have in part described this systemic-to-brain signaling pathway, we lack information on how these changes appear in humans....... This study examines the short- and long-term impact of abdominal surgery on the human brain immune system by positron emission tomography (PET) in relation to blood immune reactivity, plasma inflammatory biomarkers, and cognitive function. METHODS: Eight males undergoing prostatectomy under general...... anesthesia were included. Prior to surgery (baseline), at postoperative days 3 to 4, and after 3 months, patients were examined using [11C]PBR28 brain PET imaging to assess brain immune cell activation. Concurrently, systemic inflammatory biomarkers, ex vivo blood tests on immunoreactivity...

    OBJECTIVE: To reach an evidence-based consensus on the relative merits of vertical and transverse laparotomy incisions. DESIGN: Review of all published randomised controlled trials that compared the postoperative complications after the two main types of abdominal incisions, vertical and transverse...... postoperative pain and fewer pulmonary complications. Vertical laparotomy, however, is associated with shorter operating time and better possibilities for extension of the incision. The pooled odds ratio for burst abdomen in the vertical incision group was 2.86 (95% confidence interval 1.72 to 4.73, p = 0.......0001), and regarding late incisional hernia the pooled odds ratio was 1.68 (95% confidence interval 1.10 to 2.57. p = 0.02). CONCLUSIONS: Transverse incisions in abdominal surgery are based on better anatomical and physiological principles. They should be recommended, as the early postoperative period is associated...

    In recent 20 years, hernia and abdominal wall surgery has made great progress in China. However, what we've done still leaves much to be desired. Related guidelines of hernia disease had been conducted, but China is short of multi-center, prospective, and large-sample research evidence. These guidelines are still with low evidence level, and contents need additional modified to well meet Chinese real situation. In terms of treatment of inguinal and abdominal wall incisional hernia, some consensus has been reached from certain key issues globally, but further exploration are still needed. To stand at top of the world, we are a long distance. We should not only strengthen training and quality control but also establish patient registration system and overall management process.

    Bariatric surgery patients enter into a catabolic state postoperatively, which can lead to an aberrant wound healing process. To improve the future treatment of morbidly obese patients, the aim of our study was to understand the link between bariatric surgery and alterations in the wound healing processes. A total of 18 morbidly obese Zucker rats were separated into three groups and underwent one of three surgical procedures: Roux-en-Y gastric bypass (RYGB; n = 6); sleeve gastrectomy (GS; n = 6); or midline laparotomy only (n = 6). The rats were weighed on postoperative day 0, 3, 7, and 14. On day 14, the abdominal wall was harvested and underwent histologic and biomechanical evaluation. A significant difference was found in the weight gain between the laparotomy control group (LC) and bariatric surgical groups at 7 and 14 d. By postoperative day 7, the GS and RYGB rats weighed significantly less than the LC group, losing, on average, 7% and 6% of their initial body weight, respectively, and the LC gained 4% of their weight (P gained 20% of their original weight, and the two bariatric groups both weighed significantly less (P bariatric surgery negatively affects wound healing both histologically and biomechanically compared with nonbariatric models. Although obesity remains a significant factor in the wound healing process, understanding the link between bariatric surgery and alterations in wound healing is imperative before advocating simultaneous repair of ventral hernias during concomitant bariatric surgery.

    Assessment of dehydration in the preoperative setting is of potential clinical value. The present study uses urine analysis and plasma volume kinetics, which have both been validated against induced changes in body water in volunteers, to study the incidence and severity of dehydration before open abdominal surgery begins. Thirty patients (mean age 64 years) had their urine analysed before major elective open abdominal surgery for colour, specific weight, osmolality and creatinine. The results were scored and the mean taken to represent a 'dehydration index'. Thereafter, the patients received an infusion of 5 ml/kg of Ringer's acetate intravenously for over 15 min. Blood was sampled for 70 min and the blood haemoglobin concentration used to estimate the plasma volume kinetics. Distribution of fluid occurred more slowly (P dehydrated as compared with euhydrated patients. The dehydration index indicated that the fluid deficit in these patients corresponded to 2.5% of the body weight, whereas the deficit in the others was 1%. In contrast, the 11 patients who later developed postoperative nausea and vomiting had a very short elimination half-life, only 9 min (median, P dehydration before major surgery was modest as evidenced both by urine sampling and volume kinetic analysis. © 2014 The Acta Anaesthesiologica Scandinavica Foundation.

    Abstract Background: Laparoscopic and robot-assisted surgeries are performed under carbon dioxide insufflation. Switching from gas to an isotonic irrigant introduces several benefits and avoids some adverse effects of gas insufflation. We developed an irrigating device and apparatus designed for single-incision laparoscopic surgery and tested its advantages and drawbacks during surgery in a porcine model. Materials and Methods: Six pigs underwent surgical procedures under general anesthesia. A 30-cm extracorporeal cistern was placed over a 5–6-cm abdominal incision. The abdomen was irrigated with warm saline that was drained via a suction tube placed near the surgical field and continuously recirculated through a closed circuit equipped with a hemodialyzer as a filter. Irrigant samples from two pigs were cultured to check for bacterial and fungal contamination. Body weight was measured before and after surgery in four pigs that had not received treatments affecting hemodynamics or causing diuresis. Results: One-way flow of irrigant ensured laparoscopic vision by rinsing blood from the surgical field. Through a retroperitoneal approach, cystoprostatectomy was successfully performed in three pigs, nephrectomy in two, renal excision in two, and partial nephrectomy in one, under simultaneous ultrasonographic monitoring. Through a transperitoneal approach, liver excision and hemostasis with a bipolar sealing device were performed in three pigs, and bladder pedicle excision was performed in one pig. Bacterial and fungal contamination of the irrigant was observed on the draining side of the circuit, but the filter captured the contaminants. Body weight increased by a median of 2.1% (range, 1.2–4.4%) of initial weight after 3–5 hours of irrigation. Conclusions: Surgery under irrigation is feasible and practical when performed via a cistern through a small abdominal incision. This method is advantageous, especially in the enabling of continuous and free

    Currently, hospital benchmarking organizations are often limited to short-term surgical quality comparisons among hospitals. The goal of this study was to determine whether long-term rates of incisional hernia repair after common abdominal operations could be used to compare hospital long-term surgical quality. This was a cohort study with up to 4 years of follow-up. Patients who underwent 1 of 5 common inpatient abdominal operations were identified in 2005-2008 American College of Surgeons NSQIP data linked to Medicare inpatient records. The main outcomes included occurrence of an incisional hernia repair. A multivariable, shared frailty Cox proportional hazards regression was used to compare each hospital's incisional hernia rate with the overall mean rate for all hospitals and control for American College of Surgeons NSQIP preoperative clinical variables. A total of 37,134 patients underwent 1 of 5 common inpatient abdominal operations, including colectomy, small bowel resection, ventral hernia repair, pancreatic resection, or cholecystectomy, at 1 of 216 hospitals participating in American College of Surgeons NSQIP during the 4-year period. There were 1,474 (4.0%) patients who underwent an incisional hernia repair, at a median follow-up time of 16 months (interquartile range 8 to 25 months) after initial abdominal surgery. After risk adjustment, there was no significant difference in the ratio of any one hospital's adjusted hazard rate for incisional hernia repair vs the average hospital adjusted hazard rate. Risk-adjusted hospital rates of incisional hernia repair do not vary significantly from the average. This suggests that incisional hernia repair might not be sensitive enough as a long-term quality metric for benchmarking hospital performance. Copyright © 2015 American College of Surgeons.

    The objective of this study was to evaluate the potential benefits of immunonutrition in major abdominal surgery with special regard to subgroups and influence of bias. A systematic literature search from January 1985 to July 2015 was performed in MEDLINE, Embase and CENTRAL. Only RCTs investigating immunonutrition in major abdominal surgery were included. Outcomes evaluated were mortality, overall complications, infectious complications and length of hospital stay. The influence of different domains of bias was evaluated in sensitivity analyses. Evidence was rated according to the GRADE Working Group grading of evidence. A total of 83 RCTs with 7116 patients were included. Mortality was not altered by immunonutrition. Taking all trials into account, immunonutrition reduced overall complications (odds ratio (OR) 0·79, 95 per cent c.i. 0·66 to 0·94; P = 0·01), infectious complications (OR 0·58, 0·51 to 0·66; P high and unclear risk of bias. Publication bias seemed to be present for infectious complications (P = 0·002). Non-industry-funded trials reported no positive effects for overall complications (OR 1·13, 0·88 to 1·46; P = 0·34), whereas those funded by industry reported large effects (OR 0·66, 0·48 to 0·91; P = 0·01). Immunonutrition after major abdominal surgery did not seem to alter mortality (GRADE: high quality of evidence). Immunonutrition reduced overall complications, infectious complications and shortened hospital stay (GRADE: low to moderate). The existence of bias lowers confidence in the evidence (GRADE approach). © 2017 BJS Society Ltd Published by John Wiley & Sons Ltd.

    BACKGROUND Patient volume is assumed to affect quality, whereby complex procedures are best performed by those who perform them frequently. We have conducted a systematic review of the research on the association between patient volume and quality of vascular surgery. In this article we describe the outcomes for abdominal aortic aneurysm surgery.MATERIAL AND METHOD We undertook systematic searches in relevant databases. We searched for systematic reviews, and randomised and observational studies. The search was concluded in December 2015. We have summarised the results descriptively and assessed the overall quality of the evidence.RESULTS Forty-six observational studies fulfilled our inclusion criteria. We found a possible association for both hospital and surgeon volume. Higher patient volume may possibly be associated with lower 30-day mortality and lower hospital mortality for both open and endovascular surgery. Although the association appears to apply to both elective and acute hospitalisations, there is greater uncertainty with regard to the most ill patients. For hospital volume there may also be fewer complications for open and endovascular surgery, as well as for all surgery assessed as a whole. We considered the evidence base to be medium to very low quality.INTERPRETATION We found a possible correlation between patient volume and quality indicators such as mortality and complications. It may be advantageous to allocate planned procedures to institutions and surgeons with high volume, while this is less certain with regard to acute hospitalisations.

    To compare efficacy and safety of thromboprophylaxis with semuloparin started postoperatively versus enoxaparin started preoperatively in major abdominal surgery. Venous thromboembolism is an important complication following major abdominal surgery. Semuloparin is a novel ultra-low-molecular-weight heparin with high antifactor Xa and minimal antifactor IIa activity. In this double-blind noninferiority trial, adult patients undergoing major abdominal or pelvic operation under general anesthesia lasting more than 45 minutes were assigned to either daily enoxaparin 40 mg commenced preoperatively or daily semuloparin 20 mg commenced postoperatively, for 7 to 10 days. Patients underwent bilateral leg venography between 7 and 11 days postsurgery. The primary efficacy end point was the composite of any deep vein thrombosis, nonfatal pulmonary embolism, or all-cause death. The primary safety outcome was bleeding. Both were independently adjudicated. In total, 4413 patients were randomized; 3030 (1499 in the enoxaparin and 1531 in the semuloparin groups) were evaluable for the primary efficacy end point, which occurred in 97 patients (6.3%) in the semuloparin group and 82 patients (5.5%) in the enoxaparin group [odds ratio (OR) = 1.16, 95% confidence interval (CI): 0.84-1.59]. On the basis of a noninferiority margin of 1.25, postoperative semuloparin did not demonstrate noninferiority to preoperative enoxaparin. Major bleeding occurred in 63 of 2175 patients (2.9%) in the semuloparin group and 98 of 2177 patients (4.5%) in the enoxaparin group (OR = 0.63, 95% CI: 0.46-0.87). Semuloparin commenced postoperatively did not demonstrate noninferiority to enoxaparin initiated preoperatively for thromboprophylaxis after major abdominal surgery. Study registered with clinicaltrials.gov: NCT00679588.

    To compare the rates of abdominal surgery during pregnancy among women with previous bariatric surgery (women in the case group) and women with first-trimester body mass index (BMI) greater than 35 and no previous bariatric surgery (women in the control group). We conducted a national cohort study, merging data from the Swedish Medical Birth Registry and the Swedish National Patient Registry, comparing women who had bariatric surgery from 1987 to 2011 with women in a control group with first-trimester BMI greater than 35 who had not had bariatric surgery. Primary outcome variables were diagnosis and surgical procedure codes grouped as five outcome categories: 1) intestinal obstruction, 2) gallbladder disease, 3) appendicitis, 4) hernia, and 5) diagnostic laparoscopy or laparotomy without the presence of a diagnosis or surgical code for outcomes in outcome categories 1-4. Odds ratios were computed using multivariate linear regression analysis for each separate pregnancy. For all pregnancies in a given woman, general estimating equations with robust variance estimation were used. Adjustment was made for smoking, year of delivery, maternal age, and previous abdominal surgery. During the first pregnancy after bariatric surgery, the rate of surgery for intestinal obstruction was 1.5% (39/2,543; 95% confidence interval [CI] 1.1-2.0%) in women in the case group compared with 0.02% (4/21,909; 95% CI 0.0-0.04%) among women in the control group (adjusted odds ratio [OR] 34.3, 95% CI 11.9-98.7). Similarly, the rate of diagnostic laparoscopy or laparotomy was 1.5% (37/2,542; 95% CI 1.0-1.9%) among women in the case group compared with 0.1% (18/21,909; 95% CI 0.0-0.1%) among women in the control group (adjusted OR 11.3, 95% CI 6.9-18.5). Bariatric surgery is associated with an increased risk of abdominal surgery during pregnancy.

    To describe the use of postoperative intrajejunal feeding and to evaluate the association of preoperative plasma albumin concentrations with intrajejunal feeding-related complications and clinical outcome. Prospective, observational study. University veterinary teaching hospital. Sixty-four dogs. Jejunostomy tube placement during abdominal surgery. Most dogs (81%) survived. The median intrajejunal feeding period was 2.1 days (range: 1-16 days; n = 64). Only 3 (5%) dogs received their estimated resting energy requirement by intrajejunal feeding. Of dogs that were fed intrajejunally (58 out of 64), most (55 out of 58) received intrajejunal feeding within 24 hours after surgery. Energy provision via the jejunal feeding tube did not differ between dogs with and without complications (P = 0.592), or between nonsurvivors and survivors (P = 0.298). Thirty-five dogs ate voluntarily concurrently with intrajejunal feeding. Of dogs that ate voluntarily concurrently with intrajejunal feeding for ≤50% of the postoperative period, most (74%) survived to discharge. Complications were seen in 22% of dogs, and none were life-threatening; gastrointestinal signs were most common. There was no difference in preoperative plasma albumin concentration between dogs with and without complications (P = 0.432) and between nonsurvivors and survivors (P = 0.727). Fecal score was not significantly different between the 2 liquid diets studied (FormulaV Enteral Care HLP and CliniCare Canine/Feline; P = 0.927). A jejunostomy tube placed during abdominal surgery was likely to be used at the study institution. Few complications were seen and none were life-threatening. Intrajejunal feeding was initiated early after surgery and did not interfere with the initiation of voluntary oral intake. Fecal scores were high and were useful for an objective assessment of fecal consistency in dogs with intrajejunal feeding. © Veterinary Emergency and Critical Care Society 2016.

    In-depth historical research is made on Arabic contributions to surgery of the abdominal cavity highlighting their specific achievements in laparotomy and caesarian section. Albucasis (936-1013) in his book "Al Tasrif" produced the first authentic description ever contained in the literature on surgery of the abdomen. He described methods of bowel reduction and abdominal wall closure. Albucasis used Arabian ant-nippers for intestinal anastomosis; he was the first to sew the intestine with fine suture extracted from animal's gut. The manuscript of Shahnama or "Book of Kings" written by Ferdowsi (1560-1580) (possessed by the Metropolitan Museum of Art in New York), described the earliest caesarian section performed on Persian Rustam many centuries B.C. Edinburgh University Library has the manuscript entitled "Al-Athar Al-Baqiya An Alqurun Al-Khaliyah" by Al-Biruni (1307-1308); it revealed that section had probably been performed on living wives of Muslim Kings. Plates No. 65, 73, 81 and 82 illustrating Muslim Surgeons performing section were gathered from last two books by Brandenburg in 1982.

    The approach to the abdominal wall surgical repair is dramatically changed in the last years. This study evaluates our institutional outcomes about the usage of biological meshes for abdominal wall repair in different setting: in elective surgery, in emergency surgery and in abdominal wall repair following open abdomen (OA) procedure. A database was prospectively conducted (January-December 2014) and data were reviewed for patients who underwent to an abdominal wall reconstruction with swine dermal non-cross linked collagens prostheses either in elective or emergency setting, and following OA/laparostomy procedure. Demographic data, co-morbidities, indications for surgery, intra-operative details, post-operative complications and outcome (peri-operative, 3, 6, 9-months) were analyzed. A total of 30 cases were reported: 9 in elective surgery (Group 1), 4 in emergency surgery (Group 2) and 17 with abdominal wall closure following OA management (Group 3). Two meshes were removed: 1 in the Group 1 and 1 in the Group 3. During follow-up only one patient in the Group 3 had a recurrence of the incisional hernia. Mortality rate was 11.1 % at 3 months in Group 1, 0 % in the Group 2, and 29.4 % in peri-operative period in the Group 3. The use of non-cross linked biological meshes can be safe and versatile in different situations from elective to emergency surgery, and also for the reconstruction of the abdominal wall after OA procedure, with an acceptable recurrence and mortality rate.

    Acute postoperative pain is still an issue in patients undergoing abdominal surgery. Postoperative pain and side effects of analgesic treatment, in particular those of opioids, need to be minimized. Opioid-sparing analgesics, possibly including dexmedetomidine, seem a promising avenue by which to improve postoperative outcomes. Our primary aim was to determine the analgesic efficacy and opioid-sparing effect of perioperative dexmedetomidine for acute pain after abdominal surgery in adults.Secondary aims were to establish effects of dexmedetomidine on postoperative nausea and vomiting (PONV), gastrointestinal function and mobilization, together with the side effect profile of dexmedetomidine. We searched the following databases: Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, Institute for Scientific Information (ISI), Web of Science and Cumulative Index to Nursing and Allied Health Literature (CINAHL), and reference lists of articles to May 2014. We searched the Science Citation Index, ClinicalTrials.gov and Current Controlled Trials, and we contacted pharmaceutical companies to identify unpublished and ongoing studies. We applied no language restrictions. We reran the search in May 2015 and found nine studies of interest. We will deal with the studies of interest when we update the review. We included randomized, controlled trials of perioperative dexmedetomidine versus placebo or other drug during abdominal surgery in adults. Trials included one of the following outcomes: amount of 'rescue' opioid, postoperative pain, time to 'rescue' analgesia, participants requiring 'rescue' analgesia, postoperative sedation, PONV, time to first passage of flatus and stool or time to first out-of-bed mobilization. Two review authors independently screened the titles and abstracts for eligibility. We retrieved full trial reports if necessary, and we extracted relevant data from the included studies using a data collection form and assessed risk of bias. We

    The objective of this study was to evaluate whether major abdominal surgery leads to complement activation and interleukin response and whether the kind of anaesthesia influence complement activation and the release of inflammatory interleukins. The study design was prospective and randomised. Fifty patients undergoing open major colorectal surgery due to cancer disease or inflammatory bowel disease were studied. Twenty-five patients were given total intravenous anaesthesia (TIVA) with propofol and remifentanil, and 25 patients were given inhalational anaesthesia with sevoflurane and fentanyl. To determine complement activation (C3a and SC5b-9) and the release of pro- and anti-inflammatory interleukins (tumour necrosis factor-a (TNF-a)), interleukin-1b (IL-1b), IL-6, IL-8, IL-4 and IL-10), blood samples were drawn preoperatively, 60 minutes after start of surgery, 30 minutes after end of surgery and 24 hours postoperatively. Complement was activated and pro-inflammatory interleukins (IL-6 and IL-8) and anti-inflammatory interleukins (IL-10) were released during major colorectal surgery. There was no significant difference between TIVA and inhalational anaesthesia regarding complement activation and cytokine release. Major colorectal surgery leads to activation of the complement cascade and the release of both pro-inflammatory and anti-inflammatory cytokines. There are no significant differences between total intravenous anaesthesia (TIVA) with propofol and remifentanil and inhalational anaesthesia with sevoflurane and fentanyl regarding complement activation and the release of pro- and anti-inflammatory interleukins. © 2012 The Authors.

    Chronic abdominal pain after bariatric surgery is associated with diagnostic and therapeutic challenges. The aim of this study was to evaluate the yield of laparoscopy as a diagnostic and therapeutic tool in post-bariatric surgery patients with chronic abdominal pain who had negative imaging and endoscopic studies. A retrospective analysis was performed on post-bariatric surgery patients who underwent laparoscopy for diagnosis and treatment of chronic abdominal pain at a single academic center. Only patients with both negative preoperative CT scan and upper endoscopy were included. Total of 35 post-bariatric surgery patients met the inclusion criteria, and all had history of Roux-en-Y gastric bypass. Twenty out of 35 patients (57%) had positive findings on diagnostic laparoscopy including presence of adhesions (n = 12), chronic cholecystitis (n = 4), mesenteric defect (n = 2), internal hernia (n = 1), and necrotic omentum (n = 1). Two patients developed post-operative complications including a pelvic abscess and an abdominal wall abscess. Overall, 15 patients (43%) had symptomatic improvement after laparoscopy; 14 of these patients had positive laparoscopic findings requiring intervention (70% of the patients with positive laparoscopy). Conversely, 20 (57%) patients required long-term medical treatment for management of chronic abdominal pain. Diagnostic laparoscopy, which is a safe procedure, can detect pathological findings in more than half of post-bariatric surgery patients with chronic abdominal pain of unknown etiology. About 40% of patients who undergo diagnostic laparoscopy and 70% of patients with positive findings on laparoscopy experience significant symptom improvement. Patients should be informed that diagnostic laparoscopy is associated with no symptom improvement in about half of cases.

    The risk of post-operative pneumonia is a latent complication. A study was conducted to determine its risk factors in abdominal surgery. A cross-sectional study was performed that included analysing the variables of age and gender, chronic obstructive pulmonary disease and smoking, serum albumin, type of surgery and anaesthesia, emergency or elective surgery, incision site, duration of surgery, length of hospital stay, length of stay in the intensive care unit, and time on mechanical ventilation. The adjusted odds ratio for risk factors was obtained using multivariate logistic regression. The study included 91 (9.6%) patients with pneumonia and 851 (90.4%) without pneumonia. Age 60 years or over (OR=2.34), smoking (OR=9.48), chronic obstructive pulmonary disease (OR=3.52), emergency surgery (OR=2.48), general anaesthesia (OR=3.18), surgical time 120 minutes or over (OR=5.79), time in intensive care unit 7 days or over (OR=1.23), time on mechanical ventilation greater than or equal to 4 days (OR=5.93) and length of post-operative hospital stay of 15 days or over (OR=1.20), were observed as independent predictors for the development of postoperative pneumonia. Identifying risk factors for post-operative pneumonia may prevent their occurrence. The length in the intensive care unit of greater than or equal to 7 days (OR=1.23; 95% CI 1.07 - 1.42) and a length postoperative hospital stay of 15 days or more (OR=1.20; 95% CI 1.07 - 1.34) were the predictive factors most strongly associated with lung infection in this study.

    Full Text Available Abstract Background There is no consensus regarding the management of ovarian cancer patients, who have shown complete clinical response (CCR to primary therapy and have rising cancer antigen CA-125 levels but have no symptoms of recurrent disease. The present study aims to determine whether follow-up CA-125 levels can be used to identify the need for imaging studies and secondary cytoreductive surgery (CRS. Methods We identified 410 ovarian cancer patients treated at The University of Texas MD Anderson Cancer Center between 1984 and 2011. These patients had shown CCR to primary therapy. Follow-up was conducted based on the surveillance protocol of the MD Anderson Cancer Center. We used the Cox proportional hazards model and log-rank test to assess the associations between the follow-up CA-125 levels and secondary CRS and survival duration. Results The CA-125 level of 1.68 × nadir was defined as the indicator of recurrent disease (p  1.68 × nadir at relapse (55.7 and 10.4 months; p = 0.04 and 0.01, respectively. The overall and progression free survival duration of patients with asymptomatic relapse and underwent a secondary CRS was longer than that of patients with symptomatic relapse (p = 0.02 and 0.04 respectively. Conclusions The increase of serum CA-125 levels is an early warning of clinical relapse in ovarian cancer. Using CA-125 levels in guiding the treatment of patients with asymptomatic recurrent ovarian cancer, who have shown CCR to primary therapy, can facilitate optimal secondary CRS and extend the survival duration of the patients.

    As the integrated vascular residency program reaches almost a decade of maturity, a common area of concern among trainees is the adequacy of open abdominal surgical training. It is our belief that although their overall exposure to open abdominal procedures has decreased, integrated vascular residents have an adequate and focused exposure to open aortic surgery during training. National operative case log data supplied by the Accreditation Council for Graduate Medical Education were compiled for both graduating integrated vascular surgery residents (IVSRs) and graduating categorical general surgery residents (GSRs) for the years 2012 to 2014. Mean total and open abdominal case numbers were compared between the IVSRs and GSRs, with more in-depth exploration into open abdominal procedures by organ system. Overall, the mean total 5-year case volume of IVSRs was 1168 compared with 980 for GSRs during the same time frame (P surgery, representing 57% of all open abdominal cases. GSRs completed an average of 116 open alimentary tract surgeries during their training. Open abdominal surgery represented an average of 7.1% of the total vascular case volume for the vascular residents, whereas open abdominal surgery represented 21% of a GSR's total surgical experience. IVSRs reported almost double the number of total cases during their training, with double chief-level cases. Sixty-five percent of open abdominal surgeries performed by IVSRs involved the aorta or its renovisceral branches. Whereas open abdominal surgery represented 7.1% of an IVSR's surgical training, GSRs had a far broader scope of open abdominal procedures, completing nearly double those of IVSRs. The differences in open abdominal procedures pertain to the differing diseases treated by GSRs and IVSRs. Copyright © 2017 Society for Vascular Surgery. Published by Elsevier Inc.

    We provide a continuation of the existing Activity Table Modeling methodology with a modular spreadsheets simulation. The simulation model developed is comprised of 28 modeling elements for the abdominal surgery cycle process. The simulation of a two-week patient flow in an abdominal clinic with 75 beds demonstrates the applicability of the methodology. The simulation does not include macros, thus programming experience is not essential for replication or upgrading the model. Unlike the existing methods, the proposed solution employs a modular approach for modeling the activities that ensures better readability, the possibility of easily upgrading the model with other activities, and its easy extension and connectives with other similar models. We propose a first-in-first-served approach for simulation of servicing multiple patients. The uncertain time duration of the activities is modeled using the function "rand()". The patients movements from one activity to the next one is tracked with nested "if()" functions, thus allowing easy re-creation of the process without the need of complex programming.

    1990-01-01

    Adrenaline-induced changes in heart rate, blood pressure, plasma adrenaline and noradrenaline, cortisol, glucagon, insulin, cAMP, glucose lactate, glycerol and beta-hydroxybutyrate were studied preoperatively and 4 and 24 h after skin incision in 8 patients undergoing elective cholecystectomy. Late...... postoperative responses of blood glucose, plasma cAMP, lactate and glycerol to adrenaline infusion were reduced, whereas other responses were unaffected. Blood glucose appearance and disappearance rate as assessed by [3H]3-glucose infusion was unchanged pre- and postoperatively. The increase in glucose...... appearance rate following adrenaline was similar pre- and postoperatively. These findings suggest that several beta-receptor-mediated responses to adrenaline are reduced after abdominal surgery....

    In this paper, a novel robot-assisted platform for single-port minimally invasive surgery is presented. A miniaturized seven degrees of freedom (dof) fully internalized in-vivo actuated robotic arm is designed. Due to in-vivo actuation, the system has a smaller footprint and can generate 20 N of gripping force. The complete work envelop of the robotic arms is 252 mm × 192 mm × 322 m. With the assistance of the cannula-swivel system, the robotic arms can also be re-positioned and have multi-quadrant reachability without any additional incision. Surgical tasks, such as lifting, gripping suturing and knot tying that are commonly used in a standard surgical procedure, were performed to verify the dexterity of the robotic arms. A single-port trans-abdominal cholecystectomy in a porcine model was successfully performed to further validate its functionality.

    Major resections for esophageal, gastric, hepatic, pancreatic, and colorectal cancer continue to be associated with a high peri-operative morbidity of up to 30%-40%. To a large extent, this morbidity is caused by infectious complications that add up to a considerable burden to patients and hospital costs. The objective of this large retrospective cross-sectional study was to determine independent patient and operation-related risk factors for infectious complications after major abdominal cancer operations to elucidate how infection rates can be reduced and improve health-care quality. In 1,389 cancer patients who underwent a major resection procedure between 2009 and 2013, infectious complications and their independent determinants were analyzed by multivariable logistic regression (p abdominal drainage (OR 1.41; p = 0.024) and a duration of surgery of ≥180 min (OR 1.85; p = 0.001) were risk factors for surgical site infections. Total parenteral nutrition was significantly associated with intravascular catheter-induced infections (OR 18.09; p abdominal cancer operations were identified, providing opportunities for further reducing peri-operative infections. General awareness and focus on preventing infectious complications may have a significant impact on health-care outcomes and costs.

    We compared two surgical approaches in patients with symptomatic prolapse of the vaginal apex with normal controls by analyzing pelvic landmark relationships measured using magnetic resonance imaging (MRI) before and after surgery. In this prospective multicenter pilot study involving 16 participants, nulliparous controls (n = 6) were compared with ten parous (3.0 ± 1.0) women with uterine apical prolapse equal to or greater than stage 2. Group A (n = 5) underwent abdominal sacral colpopexy with monofilament polypropylene mesh and group B (n = 5) with vaginal mesh kit repair (Total ProLift). Subtotal hysterectomy was performed in all group A and no group B women. All patients underwent preoperative and 3-month postoperative Pelvic Organ Prolapse Quantification (POP-Q) and dynamic MRI. Comparison of MRI pelvic angles and distances was performed and analyzed by Mann-Whitney rank sum test and chi-square test. Vaginal apical support is similar at 3 months for abdominal sacral colpopexy (ASCP) and ProLift by POP-Q examination and MRI analysis. In both treatment groups, the postoperative POP-Q point C and MRI parameters were similar to nulliparous controls at 3 months. Anatomic outcomes for ASCP compared with ProLift were similar at 3 months in terms of vaginal apical support by POP-Q and MRI analysis. Continued comparative analysis of postoperative support with objective imaging seems warranted.

    Background There is no consensus regarding the management of ovarian cancer patients, who have shown complete clinical response (CCR) to primary therapy and have rising cancer antigen CA-125 levels but have no symptoms of recurrent disease. The present study aims to determine whether follow-up CA-125 levels can be used to identify the need for imaging studies and secondary cytoreductive surgery (CRS). Methods We identified 410 ovarian cancer patients treated at The University of Texas MD Anderson Cancer Center between 1984 and 2011. These patients had shown CCR to primary therapy. Follow-up was conducted based on the surveillance protocol of the MD Anderson Cancer Center. We used the Cox proportional hazards model and log-rank test to assess the associations between the follow-up CA-125 levels and secondary CRS and survival duration. Results The CA-125 level of 1.68 × nadir was defined as the indicator of recurrent disease (p CA-125 biochemical progression prior to clinically-defined relapse was 31 days (ranging from 1 to 391 days). The median number of the negative imaging studies for the clinical relapse findings in patients with a CA-125 level of CA-125 level at relapse was an independent predictor of overall and progression free survival in patients who had shown CCR to primary therapy (p = 0.04 and 0.02 respectively). The overall and progression free survival durations in patients with a CA-125 level ≤ 1.68 × nadir at relapse (69.4 and 13.8 months) were longer than those with a CA-125 level > 1.68 × nadir at relapse (55.7 and 10.4 months; p = 0.04 and 0.01, respectively). The overall and progression free survival duration of patients with asymptomatic relapse and underwent a secondary CRS was longer than that of patients with symptomatic relapse (p = 0.02 and 0.04 respectively). Conclusions The increase of serum CA-125 levels is an early warning of clinical relapse in ovarian cancer. Using CA-125 levels in

    To investigate the survival and prognostic factors of stage 0 to III rectal cancer in 10 years. Clinical data and follow-up of 856 rectal cancer patients with stage 0-III underwent curative surgery from January 2000 to December 2010 were retrospective analyzed. There were 470 male and 386 female patients, with a mean age of (58 ± 12) years. Kaplan-Meier method was used to analyze the overall survival and disease free survival. Log-rank test was used to compare the survival between groups. Cox regression was used to analyze the independent prognostic factors of rectal cancer. The patients in each stage were stage 0 with 18 cases, stage I with 209 cases, stage II with 235 cases, and stage III with 394 cases. All patients received curative surgery. There were 296 patients evaluated as cT3, cT4 and any T with N+ received preoperative radiotherapy. 5.4% patients got pathological complete response (16/296), and the recurrence rate was 4.7% (14/296). After a median time of 41.7 months (range 4.1 to 144.0 months) follow-up, the 5-year overall survival rate in stage 0 to I of was 91.0%, stage II 86.2%, and stage III 60.0%, with a significant difference (P=0.000). The cumulative local recurrence rate was 4.8% (41/856), of which 70.7% (29/41) occurred within 3 years postoperatively, 97.6% (40/41) in 5 years. The cumulative distant metastasis rate was 16.4% (140/856), of which 82.9% (129/140) occurred within 3 years postoperatively, 96.4% (135/140) in 5 years. The incidence of abnormal imaging findings was significantly higher in pulmonary than liver and other sites metastases (75.0% vs. 21.7%, χ² =25.691, P=0.000). The incidence of CEA elevation was significantly higher in liver than lung and other sites metastases (56.8% vs. 37.8%, χ² =25.691, P=0.000). Multivariable analysis showed that age (P=0.015, HR=1.385, 95% CI: 1.066 to 1.801), surgical approach (P=0.029, HR=1.337, 95% CI: 1.030 to 1.733), differentiation (P=0.000, HR=1.535, 95% CI: 1.222 to 1.928), TNM stage (P

    This is an update of the review published in 2013.Laparoscopic surgery is now widely performed to treat various abdominal diseases. Currently, carbon dioxide is the most frequently used gas for insufflation of the abdominal cavity (pneumoperitoneum). Although carbon dioxide meets most of the requirements for pneumoperitoneum, the absorption of carbon dioxide may be associated with adverse events. People with high anaesthetic risk are more likely to experience cardiopulmonary complications and adverse events, for example hypercapnia and acidosis, which has to be avoided by hyperventilation. Therefore, other gases have been introduced as alternatives to carbon dioxide for establishing pneumoperitoneum. To assess the safety, benefits, and harms of different gases (i.e. carbon dioxide, helium, argon, nitrogen, nitrous oxide, and room air) used for establishing pneumoperitoneum in participants undergoing laparoscopic general abdominal or gynaecological pelvic surgery. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library, 2016, Issue 9), Ovid MEDLINE (1950 to September 2016), Ovid Embase (1974 to September 2016), Science Citation Index Expanded (1970 to September 2016), Chinese Biomedical Literature Database (CBM) (1978 to September 2016), ClinicalTrials.gov (September 2016), and World Health Organization International Clinical Trials Registry Platform (September 2016). We included randomised controlled trials (RCTs) comparing different gases for establishing pneumoperitoneum in participants (irrespective of age, sex, or race) undergoing laparoscopic abdominal or gynaecological pelvic surgery under general anaesthesia. Two review authors identified the trials for inclusion, collected the data, and assessed the risk of bias independently. We performed the meta-analyses using Review Manager 5. We calculated risk ratio (RR) for dichotomous outcomes (or Peto odds ratio for very rare outcomes), and mean difference (MD) or standardised

    The advantages of 3D reconstruction, immersive virtual reality (VR) and 3D printing in abdominal surgery have been enunciated for many years, but still today their application in routine clinical practice is almost nil. We investigate their feasibility, user appreciation and clinical impact. Fifteen patients undergoing pancreatic, hepatic or renal surgery were studied realizing a 3D reconstruction of target anatomy. Then, an immersive VR environment was developed to import 3D models, and some details of the 3D scene were printed. All the phases of our workflow employed open-source software and low-cost hardware, easily implementable by other surgical services. A qualitative evaluation of the three approaches was performed by 20 surgeons, who filled in a specific questionnaire regarding a clinical case for each organ considered. Preoperative surgical planning and intraoperative guidance was feasible for all patients included in the study. The vast majority of surgeons interviewed scored their quality and usefulness as very good. Despite extra time, costs and efforts necessary to implement these systems, the benefits shown by the analysis of questionnaires recommend to invest more resources to train physicians to adopt these technologies routinely, even if further and larger studies are still mandatory.

    The purpose of this study was to explore the effectiveness of the aromatherapy product QueaseEASE (QE) for decreasing postdischarge nausea (PDN) in patients undergoing outpatient abdominal surgery. Prospective exploratory study. Informed Consent was obtained preoperatively from a convenience sample of adult patients scheduled for outpatient abdominal surgery procedures. Prior to discharge, subjects were instructed in the use of QE and given instructions on how to rate their nausea on a 0-10 scale. They recorded nausea scales > 0 any time they occurred for the next 24 hours, used the QE, and recorded their nausea scales 3 minutes later. A study nurse called subjects the next day to collect the information. The sample included 70 outpatients who underwent abdominal surgery. Twenty-five participants (36%) reported experiencing PDN and their concomitant use of QE. There was a significant difference in mean age of those reporting PDN (37 years) versus those without nausea (48 years, P = .004) as well as a significant difference in mean intravenous fluid intake during hospitalization of those reporting PDN (1,310 mL) versus those without nausea (1,511 mL, P = .04). The PDN group had more female participants (72% vs 42%, P = .02), more participants that were less than 50 years of age (84% vs 53%, P = .02), and received more opioids (100% vs 76%, P = .006) than the no nausea group. The 25 PDN participants reported 47 episodes of PDN in which they used QE. For all of the 47 PDN episodes experienced, participants reported a decrease in nausea scale (0 to 10) after the use of QE; for 22 (47%) of the PDN episodes experienced, a nausea scale of 0 after using QE was reported. The mean decrease in nausea scale for all 25 participants was 4.78 (±2.12) after using QE. This study found that the aromatherapy QE was an effective treatment of PDN in select same-day abdominal surgery patients. Copyright © 2015 American Society of PeriAnesthesia Nurses.

    Frailty is associated with poor surgical outcomes in elderly patients but is difficult to measure in the emergency setting. Sarcopenia, or the loss of lean muscle mass, is a surrogate for frailty and can be measured using cross-sectional imaging. We sought to determine the impact of sarcopenia on 1-year mortality after emergency abdominal surgery in elderly patients. Sarcopenia was assessed in patients 70 years or older who underwent emergency abdominal surgery at a single hospital from 2006 to 2011. Average bilateral psoas muscle cross-sectional area at L3, normalized for height (Total Psoas Index [TPI]), was calculated using computed tomography. Sarcopenia was defined as TPI in the lowest sex-specific quartile. Primary outcome was mortality at 1 year. Secondary outcomes were in-hospital mortality and mortality at 30, 90, and 180 days. The association of sarcopenia with mortality was assessed using Cox proportional hazards regression and model performance judged using Harrell's C-statistic. Two hundred ninety-seven of 390 emergency abdominal surgery patients had preoperative imaging and height. The median age was 79 years, and 1-year mortality was 32%. Sarcopenic and nonsarcopenic patients were comparable in age, sex, race, comorbidities, American Society of Anesthesiologists classification, procedure urgency and type, operative severity, and need for discharge to a nursing facility. Sarcopenic patients had lower body mass index, greater need for intensive care, and longer hospital length of stay (p Sarcopenia was independently associated with increased in-hospital mortality (risk ratio, 2.6; 95% confidence interval [CI], 1.6-3.7) and mortality at 30 days (hazard ratio [HR], 3.7; 95% CI, 1.9-7.4), 90 days (HR, 3.3; 95% CI, 1.8-6.0), 180 days (HR, 2.5; 95% CI, 1.4-4.4), and 1 year (HR, 2.4; 95% CI, 1.4-3.9). Sarcopenia is associated with increased risk of mortality over 1 year in elderly patients undergoing emergency abdominal surgery. Sarcopenia defined by TPI is

  4. Principles of safe abdominal entry in laparoscopic gynecologic surgery

    Full Text Available Laparoscopic gynecologic surgery has been widely used with a range of benefits. However, there are complications that are related to the abdominal entry process. Serious complications are gastrointestinal tract and major blood vessel injuries. This review introduces the recent available literature to prevent and eliminate the laparoscopic entry complications. The open entry technique is associated with a significant reduction of failed entry, compared to the closed entry technique; however there is no difference in the incidence of visceral or vascular injury. Laparoscopic entry by the left upper abdomen (i.e., Palmer's point or the middle upper abdomen (i.e., the Lee-Huang point could be considered in patients with suspected periumbilical adhesions or a history of umbilical hernia, or after three failed attempts of insufflation at the umbilicus. The Lee-Huang point has its own benefit for the operative laparoscopy in large pelvic pathologies and gynecology malignancy cases. The angle of Veress needle insertion varies from 45° in nonobese women to 90° in extraordinarily obese women. The high intra-peritoneal pressure entries, which range from 20 mmHg to 25 mmHg, minimize the risk of vascular injury. Therefore, this will not adversely affect the cardiopulmonary function in healthy women. The Veress intraperitoneal pressure (<10 mmHg is a reliable indicator of correct intraperitoneal placement of the Veress needle. The elevation of anterior abdominal wall for placement of a Veress needle increases the risks of failed entry and shows no advantage in regard to vascular or visceral complications. Surgeons should continue to increase their knowledge of anatomy, their training, and their experience to decrease laparoscopic complications.

    Intraoperative hypothermia during both open and laparoscopic abdominal surgery may be associated with adverse events. For laparoscopic abdominal surgery, the use of heated insufflation systems for establishing pneumoperitoneum has been described to prevent hypothermia. Humidification of the insufflated gas is also possible. Past studies on heated insufflation have shown inconclusive results with regards to maintenance of core temperature and reduction of postoperative pain and recovery times. To determine the effect of heated gas insufflation compared to cold gas insufflation on maintaining intraoperative normothermia as well as patient outcomes following laparoscopic abdominal surgery. We searched Cochrane Colorectal Cancer Specialised Register (September 2016), the Cochrane Central Register of Controlled Trials (CENTRAL; The Cochrane Library 2016, Issue 8), Ovid MEDLINE (1950 to September 2016), Ovid Embase (1974 to September 2016), International Pharmaceutical Abstracts (IPA) (September 2016), Web of Science (1985 to September 2016), Scopus, www.clinicaltrials.gov and the National Research Register (1956 to September 2016). We also searched grey literature and cross references. Searches were limited to human studies without language restriction. Only randomised controlled trials comparing heated (with or without humidification) with cold gas insufflation in adult and paediatric populations undergoing laparoscopic abdominal procedures were included. We assessed study quality in regards to relevance, design, sequence generation, allocation concealment, blinding, possibility of incomplete data and selective reporting. Two review authors independently selected studies for the review, with any disagreement resolved in consensus with a third co-author. Two review authors independently performed screening of eligible studies, data extraction and methodological quality assessment of the trials. We classified a study as low-risk of bias if all of the first six main

    Current practice guidelines for antimicrobial prophylaxis in surgery recommend a cephamycin or cefazolin plus metronidazole for various abdominal surgeries. In February 2016, cephamycin drug shortages resulted in a change in The Johns Hopkins Hospital's (JHH) recommendation for peri-operative antibiotic prophylaxis in abdominal surgeries from cefotetan to cefazolin plus metronidazole. The primary objective of this study was to quantify the percentage of abdominal surgeries adherent to JHH peri-operative antibiotic prophylaxis guidelines. A sub-group analysis investigated whether prophylaxis with cefazolin plus metronidazole was associated with a lower rate of surgical site infections (SSIs) versus cefotetan. This retrospective cohort study included adult inpatients who underwent an abdominal surgery at JHH in September 2015 (Study Period I: cefotetan) or February to March 2016 (Study Period II: cefazolin plus metronidazole). Two hundred abdominal surgery cases were included in the primary analysis. A subset of 156 surgical cases were included in the sub-group analysis. The overall adherence rate to JHH guidelines was 75% in Study Period I versus 17% in Study Period II (p operative administration time (87% vs. 23%, p site infections occurred in 14% (12/83) of surgeries with cefotetan versus 8.2% (6/73) with cefazolin plus metronidazole for prophylaxis (p = 0.19). Adherence to an institution-specific peri-operative antibiotic prophylaxis guideline for abdominal surgeries was limited primarily by the longer infusion time required for pre-operative metronidazole. A higher percentage of SSIs occurred among abdominal surgeries with cefotetan versus cefazolin plus metronidazole for prophylaxis.

    Objectives Increasing number of mechanical circulatory assist devices (MCADs) are being placed in heart failure patients. Morbidity from device placement is high and the outcome of patients who require noncardiac surgery after, is unclear. As laparoscopic interventions are associated with decreased morbidity, we examined the impact of such procedures in these patients. Methods A retrospective review was conducted on 302 patients who underwent MCAD placement from 2005 to 2012. All laparoscopic abdominal surgeries were included and impact on postoperative morbidity and mortality studied. Results Ten out of 16 procedures were laparoscopic with 1 conversion to open. Seven patients had a HeartMate II, 2 had Total Artificial Hearts, and 1 had CentriMag. Four patients had devices for ischemic cardiomyopathy and 6 cases were emergent. Surgeries included 6 laparoscopic cholecystectomies, 2 exploratory laparoscopies, 1 laparoscopic colostomy takedown, and 1 laparoscopic ventral hernia repair with mesh. Median age of the patients was 63 years (range, 29-79 years). Median operative time was 123 minutes (range, 30-380 minutes). Five of 10 patients were on preoperative anticoagulation with average intraoperative blood loss of 150 mL (range, 20-700 mL). There were 3 postoperative complications; acute respiratory failure, acute kidney injury and multisystem organ failure resulting in death not related to the surgical procedure. Conclusion The need for noncardiac surgery in post-MCAD patients is increasing due to limited donors and due to more durable and longer support from newer generation assist devices. While surgery should be approached with caution in this high-risk group, laparoscopic surgery appears to be a safe and successful treatment option. © The Author(s) 2016.

    Full Text Available Acute pericarditis is common but illusive, often mimicking acute coronary syndrome in its clinical and electrocardiographic presentation. Regional pericarditis, though rare, presents further challenge with a paucity of published diagnostic criteria. We present a case of postoperative regional pericarditis and discuss helpful electrocardiographic findings. A 66-year-old male with history of open drainage of a liver abscess presented with abdominal pain and tenderness. CT of the abdomen was concerning for pneumatosis intestinalis of the distal descending colon. He underwent lysis of liver adhesions; exploration revealed only severe colonic impaction, for which he had manual disimpaction and peritoneal irrigation. Postoperatively, he developed sharp chest pain. Electrocardiogram revealed inferior ST elevation. Echocardiogram revealed normal left and right ventricular dimensions and systolic function without wall motion abnormalities. Emergent coronary angiography did not identify a culprit lesion, and left ventriculogram showed normal systolic function without wall motion abnormalities. He received no intervention, and the diagnosis of regional pericarditis was entertained. His cardiac troponin was 0.04 ng/dL and remained unchanged, with resolution of the ECG abnormalities in the following morning. Review of his preangiography ECG revealed PR depression, downsloping baseline between QRS complexes, and reciprocal changes in the anterior leads, suggestive of regional pericarditis.

    The Centers for Medicare & Medicaid Services (CMS) recently released the Overall Hospital Quality Star Rating to help patients compare hospitals based on a 5-star scale. The star rating was designed to assess overall quality of the institution; thus, its validity toward specifically assessing surgical quality is unknown. To examine whether CMS high-star hospitals (HSHs) have improved patient outcomes and resource use in advanced laparoscopic abdominal surgery compared with low-star hospitals (LSHs). Using the University HealthSystem Consortium database (which includes academic centers and their affiliate hospitals) from January 1, 2013, through December 31, 2015, this administrative database observational study compared outcomes of 72 662 advanced laparoscopic abdominal operations between HSHs (4-5 stars) and LSHs (1-2 stars). The star rating includes 57 measures across 7 areas of quality. Patients who underwent advanced laparoscopic abdominal surgery, including bariatric surgery (sleeve gastrectomy, Roux-en-Y gastric bypass), colorectal surgery (colectomy, proctectomy), or hiatal hernia surgery (paraesophageal hernia repair, Nissen fundoplication), were included. Risk adjustment included exclusion of patients with major and extreme severity of illness. Main outcome measures included serious morbidity, in-hospital mortality, intensive care unit admissions, and cost. A total of 72 662 advanced laparoscopic abdominal operations were performed in patients at 66 HSHs (n = 38 299; mean [SD] age, 51.26 [15.25] years; 12 096 [31.5%] male and 26 203 [68.4%] female; 28 971 [75.6%] white and 9328 [24.4%] nonwhite) and 78 LSHs (n = 34 363; mean [SD] age, 49.77 [14.77] years; 9902 [28.8%] male and 24 461 [71.2%] female; 21 876 [67.6%] white and 12 487 [32.4%] nonwhite). The HSHs were observed to have fewer intensive care unit admissions (1007 [2.6%] vs 1711 [5.0%], P abdominal surgery. No significant difference was found in serious morbidity between HSHs and

    To examine the effect of an alpha-2 agonist, clonidine, on oxygen uptake and on the incidence of postoperative shivering, 28 patients presenting for major abdominal surgery were randomly assigned in a double-blind manner to one of two groups. Intraoperatively, 14 patients received 5 micrograms.kg-1 clonidine infused over 3 h (clonidine group), and 14 patients received placebo (placebo group). Oxygen uptake was measured continuously over the first 3 postoperative hours with a mass spectrometer system. Circulatory variables, esophageal temperature, and skin temperature were measured over the first 6 postoperative hours. Heart rate, mean arterial pressure, rate pressure product, and norepinephrine concentration were decreased in the clonidine group (P less than 2 x 10(-4)). There were no differences among groups in the incidence of shivering and in the rate of increase of esophageal temperature. By contrast, oxygen uptake was lower in the clonidine group (P = 4 x 10(-4)). This contrasting pattern may be secondary to a reduction in the intensity of mean muscular tremor in the clonidine group.

    Measurement of central venous oxygen saturation has become a surrogate parameter for fluid administration, blood transfusions and treatment with catecholamines in (early) goal directed therapy in the treatment of acute septic patients. These strategies are not easily transferred to the postoperative management of abdominal surgery due to the different conditions in surgical patients. A study population of 15 patients (8 females/7 males) underwent elective major abdominal surgery: 6 gastrectomies, 5 major liver resections and 4 lower anterior rectum resections. Surgery was performed for primary or secondary malignancy. The patients' age was 65.4+/-12.7 (mean+/-standard deviation, range 44-84, median 62) years. Blood samples were taken intraoperatively from indwelling central venous lines as well as from draining veins at the surgical site. Blood gas analyses to determine the oxygen saturations were performed immediately. All patients were operated in standardized general anesthesia including epidural analgesia and in a balanced volume status. Central venous oxygen saturations and oxygen saturations in blood from the draining veins of the surgical site showed a wide range with high intra- and interindividual differences intraoperatively. Overall, at most time points no correlation between the two oxygen saturations could be detected in three operation types. A significant correlation was only observed at one time point during liver resections. Our results show a lack of correlation between central venous oxygen saturations and oxygen saturations in the draining veins of the surgical site during major abdominal surgery. Measurement of central venous oxygen saturations does not seem to be a good surrogate for the local oxygen supply in the field of interest in major abdominal surgery even under standardized conditions.

    Measuring the quality of surgical care is essential to identifying areas of weakness in the delivery of effective surgical care and to improving patient outcomes. Our objectives were to (1) assess the quality of surgical care delivered to adult patients; and (2) determine the association between quality of surgical care and postoperative complications. This retrospective, pilot, cohort study was conducted at a single university-affiliated institution. Using the institution's National Surgical Quality Improvement Program database (2009-2010), 273 consecutive patients ≥18 years of age who underwent elective major abdominal operations were selected. Adherence to 10 process-based quality indicators (QIs) was measured and quantified by calculating a patient quality score (no. of QIs passed/no. of QIs eligible). A pass rate for each individual QI was also calculated. The association between quality of surgical care and postoperative complications was assessed using an incidence rate ratio, which was estimated from a Poisson regression. The mean overall patient quality score was 67.2 ± 14.4% (range, 25-100%). The mean QI pass rate was 65.9 ± 26.1%, which varied widely from 9.6% (oral intake documentation) to 95.6% (prophylactic antibiotics). Poisson regression revealed that as the quality score increased, the incidence of postoperative complications decreased (incidence rate ratio, 0.19; P = .011). A sensitivity analysis revealed that this association was likely driven by the postoperative ambulation QI. Higher quality scores, mainly driven by early ambulation, were associated with fewer postoperative complications. QIs with unacceptably low adherence were identified as targets for future quality improvement initiatives. Copyright © 2014 Mosby, Inc. All rights reserved.

    Postoperative pneumonia is a common complication of abdominal surgery in the elderly. The aim of this study was to determine risk factors and bacterial spectrum for pneumonia after abdominal surgery in elderly Chinese patients. We performed a case-control study in a total of 5431 patients aged 65 years and over who had undergone abdominal surgery at the 2nd affiliated hospital of Kunming medical college between June 2003 and June 2011. Postoperative pneumonia developed in 86 patients (1.58%). Gram-negative bacilli were the principal microorganisms (82.86%) isolated from patients. The most common organisms isolated were Klebsiella spp. (28.57%), Acinetobacter spp. (17.14%) and Pseudomonas aeruginosa (17.14%). Multivariate analysis confirmed the following to be independent risk factors for postoperative pneumonia in the elderly after abdominal surgery: age ≥70 (OR 1.93, 95% CI 1.16-3.22, p=0.01), upper abdominal surgery (OR 2.07, 95% CI 1.18-3.64, p=0.01) and duration of operation >3 h (OR 2.48, 95% CI 1.49-4.15, p=0.00). Identifying these risk factors may help achieve better prevention and treatment for postoperative pneumonia in elderly patients after abdominal surgery. Copyright © 2014 Elsevier Ireland Ltd.

    Full Text Available Cardiac surgery associated acute kidney injury is a major postoperative complication and has long been associated with adverse outcomes. However, the association of lactate and AKI has not been well established. The study aimed to explore the association of normalized lactate load with AKI in patients undergoing cardiac surgery.This was a prospective observational cohort study conducted in a 47-bed ICU of a tertiary academic teaching hospital from July 2012 to January 2014. All patients undergoing cardiopulmonary bypass surgery were included. Normalized lactate load (L was calculated by the equation: [Formula: see text], where ti was time point for lactate measurement and vi was the value of lactate. L was transformed by natural log (Lln to improve its normality. Logistic regression model was fitted by using stepwise method. Scale of Lln was examined by using fractional polynomial approach and potential interaction terms were explored.A total of 117 patients were included during study period, including 17 AKI patients and 100 non-AKI patients. In univariate analysis Lln was significantly higher in AKI as compared with non-AKI group (1.43±0.38 vs 1.01±0.45, p = 0.0005. After stepwise selection of covariates, the main effect logistic model contained variables of Lln (odds ratio: 11.1, 95% CI: 1.22-101.6, gender, age, baseline serum creatinine and fluid balance on day 0. Although the two-term fractional polynomial model was the best-fitted model, it was not significantly different from the linear model (Deviance difference = 6.09, p = 0.107. There was no significant interaction term between Lln and other variables in the main effect model.Our study demonstrates that Lln is independently associated with postoperative AKI in patients undergoing CPB. There is no significant interaction with early postoperative fluid balance.

    2016-12-01

    and purpose: Postoperative atrial fibrillation (POAF) is a frequent complication post high-risk abdominal surgery in elderly patients. This study aimed to develop a predictive model of POAF based on preoperative transthoracic echocardiography (TTE) findings in these patients. We conducted a prospective study of 300 consecutive patients, age ≥ 65 years (mean age 72±6 years, 61% men), who underwent high-risk abdominal surgery under general anesthesia. Preoperative TTE was performed in all patients, including tissue Doppler imaging (TDI). We measured the time interval between the onset of the P-wave on ECG and a point of the peak-A wave on TDI from the lateral mitral annulus (PA lateral) and septal mitral annulus (PA septal). Left atrial (LA) dyssynchrony was measured by subtracting the PA septal from PA lateral. Right ventricular systolic pressure was estimated by using the tricuspid regurgitation jet (TRJ) Doppler velocity method. The primary endpoint was the occurance of new-onset POAF. Thirty-seven (12%) patients developed POAF. Multiple echocardiographic parameters were measured and tested in different combinations. The final model included the following variables with cutoff points predictive of POAF: PA lateral > 139 ms (69% sensitivity, 92% specificity), LA dyssynchrony > 35 ms (78% sensitivity, 89% specificity), and TRJ Doppler velocity >2.6 m/s (89% sensitivity, 64% specificity). A value of 0 was assigned when the result was below the cutoff point and a value of 1 if above the cutoff point. Coding of these three variables in the following order: PA lateral- TRJ Doppler- left atrial dyssynchrony can predict the probability of POAF. The model showed a postive predictive value of 79% and a negative predictive value of 95%. A model using three echocardiographic variables: PA lateral, LA dyssynchrony and TRJ Doppler velocity, can predict the incidence of POAF after high-risk abdominal surgery. The model can be used preoperatively to identify high-risk patients

    The study aimed to estimate the value of embryonal natural orifice transluminal endoscopic surgery (ENOTES) in treating severe acute pancreatitis (SAP) complicated with abdominal compartment syndrome (ACS). The patients, who were randomized into an ENOTES group and an operative group, underwent ENOTES and laparotomy, respectively. The results and complications of the two groups were compared. Enterocinesia was observed earlier in the ENOTES group than in the operative group. Acute Physiology and Chronic Health Evaluation II (APACHE II) score of patients in the ENOTES group was lower than that of the operative group on the 1st, 3rd and 5th post-operative day (Pcomplications and mortality between the two groups (Pcomplications.

    A 14-year-old girl weighing 32 kg was diagnosed with suprasellar tumor causing hydrocephalus, hypothyroidism, adrenal dysfunction and central diabetes insipidus. She was treated with levothyroxine and hydrocortisone and urged to take fluid to replace urine. She was scheduled to undergo ventricular drainage to relieve hydrocephalus prior to tumor resection. For the first surgery, desmopressin was not started and urine output reached 4,000 to 6,000 ml x day(-1), urine osmolality 64 mOsm x l(-1) and urine specific gravity 1.002. Anesthesia was induced with sevoflurane and maintained with propofol and remifentanil. Maintenance fluid was with acetated Ringer's solution and urine loss was replaced with 5% dextrose. Bradycardia and hypotension occurred after intubation, which was treated with volume load. Infusion volume was 750 ml and urine output was 1100 ml during 133 min of anesthesia. Postoperative day 1 nasal desmopressin was started. Ten days later, partial tumor resection was performed. Anesthesia was induced with propofol and fentanyl and maintained with sevoflurane and remifentanil. Infusion volume was 610 ml, urine output 380 ml, and blood loss 151 ml during 344 min of anesthesia. Hemodynamic parameters were stable throughout the procedure. Pathology of the tumor was revealed to be germinoma. Bradycardia and hypotension experienced during the first surgery was suspected to be caused by preoperative hypovolemia brought by polyuria. Desmopressin was proved to be effective to treat excessive urine output and to maintain good perioperative water balance.

    Full Text Available The goal of the study was to evaluate the effect of a recruitment maneuver on respiratory biomechanics, oxygenation, and hemodynamics in patients suffering from chronic heart failure with different peripheral chemoreflex sensitivity. The study was conducted in 115 elderly patients which underwent major abdominal surgery under general/epidural surgery. Peripheral chemoreflex sensitivity (PCS was evaluated with breath-holding duration (BHD during breath-holding test. All patients were divided into two groups: group H had a high PCS (BHD = 38 seconds or less, n=49; Group M had a middle PCS (BHD more than 38 seconds, n=66. Recruitment maneuver improved oxygenation and respiratory biomechanics in all cases. However, cardiac output decreased by an average of 18%–31% in group H compared to 18%–28% in group M. SVR either remained unchanged or decreased by up to 14% of the initial value in group H, while, in group M, it had a tendency to increase, which was 24% of the initial value. So, recruitment maneuver is an effective method to improve oxygenation and biomechanical properties of the respiratory system but in patients with increased peripheral chemoreflex sensitivity it associates with the risk of hemodynamic disturbances.

    The purpose of the study was to compare laparoscopic total radical hysterectomy with classic radical hysterectomy regarding parametrial, and vaginal resection, and lymphadenectomy. Laparoscopic or laparotomic total radical hysterectomy with advantages and disadvantages was offered to the patients diagnosed as having operable cervical cancer between 2007 and 2010. Lymph node status, resection of the parametria and vagina, and margin positivity were recorded for both groups. Data were collected prospectively. Statistical analysis was performed with the SPSS statistical software program. Totally, 53 cases had classical abdominal radical hysterectomy and 35 laparoscopic radical hysterectomy, respectively. Parametrial involvement was detected in four (11.4%) cases in laparoscopic radical surgery versus nine (16.9%) in laparatomic surgery. All the cases with parametrial involvement had free surgical margins of tumor. Also there were no significant statistical differences in lymph node number and metastasis between the two groups. There is no difference in anatomical considerations between laparoscopic and laparatomic radical surgery in the surgical management of cervical cancer.

    to verify the physiotherapy performance in the respiratory and motor affections during postoperative period in pediatric patients undergoing abdominal surgery. was a literature review of articles published in the databases Lilacs, Medline and SciELO in the period 1983 to 2010 as well as books, papers presented at scientific meetings and journals of the area, who approached the post-therapy of abdominal surgery in children. The keywords used were: abdominal surgery, children and physiotherapy. 28 articles, one book chapter and one dissertation had been selected that examined the question and proposed that contained all, or at least two of the descriptors listed. Most of the material included covers the incidence of respiratory complications after surgery for pediatric abdominal surgery due to immaturity of the respiratory system of this population, abdominal manipulation of surgical period, the prolonged time in bed, pain at the incision site and waste anesthetic. Some authors also discuss the musculoskeletal and connective tissue arising from the inaction and delay of psychomotor development consequent to periods of hospitalization in early childhood, taking on the role of physiotherapy to prevent motor and respiratory involvement. there are few publications addressing this topic, but the positive aspects of physiotherapy have been described, especially in relation to the prevention of respiratory complications and motor, recognized the constraints and consequences of hospitalizations and surgeries cause in children.

    The reoperation is considered as the access to the abdominal cavity before complete healing of the surgical wound from a previous operation within the first 60 days after the first procedure. It occurs in 0.5 to 15% of patients undergoing abdominal surgery and generates significant increase in morbidity and mortality in patients undergoing abdominal surgery. Identify the number of unplanned abdominal surgical reoperations and identify the causes of these unplanned reoperations were performed in our department. This is a retrospective study conducted at the University Hospital of Puebla in the period between April 2009 to February 2012, a total of 1,709 abdominal surgeries performed by the Service of General Surgery were included. Ninety-seven cases of reoperation of which 50 cases were not planned surgery cases were identified; 72% (36 cases) from emergency operations, and 28% of elective surgery. The incidence found in our study is low compared to similar studies. Prospective studies and focus on risk factors and causes of unplanned reoperations are required, in order to know them in detail and, consequently, reduce its incidence and morbidity and mortality they add.

    2008-01-01

    The abdominal compartment syndrome is a life threatening clinical entity which can develop within the first 12 hours of intensive care unit admission in high-risk surgical patients. The aim of this paper is to show the definitions, ethiology, pathophysiology, diagnosis and treatment of this serious, not only surgical problem. The mortality due to the abdominal compartment syndrome is extremely high (38-71%). It can be defined as adverse physiologic consequences that occur as a result of an acute increase in the intraabdominal pressure. The most common causes are retroperitoneal haemorrhage, visceral oedema, pancreatitis, bowel obstruction, tense ascites, peritonitis, tumor. The mostly affected systems are cardiovascular, pulmonary, renal, central nervous systems and splanchnic organs. The gold standard diagnostic method is the continuous intra-abdominal pressure monitoring. The treatment consists of adequate fluid resuscitation and surgical decompression. We show three typical short case reports treated by the above mentioned theories. Intraabdominal hypertension and abdominal compartment syndrome are frequent clinical findings among acute general surgical patients. Patients with comparable demographics and acute severity of illness are more likely to die if intraabdominal hypertension or abdominal compartment syndrome is present. We conclude that the early recognition and surgical decompression is urgent.

    Administration of supplemental oxygen in the perioperative period is controversial, as it may increase long-term mortality. Our aim was to assess the association between 80% oxygen and occurrence of subsequent cancer in patients undergoing abdominal surgery in a post hoc analysis of the PROXI trial. The 1386 patients in the PROXI trial underwent elective or emergency laparotomy between 2006 and 2008 with randomization to either 80% or 30% oxygen during and for 2 h after surgery. We retrieved follow-up status regarding vital status, new cancer diagnoses, and new histological cancer specimens. Data were analysed using the Cox proportional hazards model. Follow-up was complete in 1377 patients (99%) after a median of 3.9 yr. The primary outcome of new cancer diagnosis or new malignant histological specimen occurred in 140 of 678 patients (21%) in the 80% oxygen group vs 150 of 699 patients (21%) assigned to 30% oxygen; hazards ratio 1.06 [95% confidence interval (CI) 0.84, 1.34], P=0.62. Cancer-free survival was significantly shorter in the 80% oxygen group; hazards ratio 1.19 (95% CI 1.01, 1.42), P=0.04, as was the time between surgery and new cancer, median 335 vs. 434 days in the 30% oxygen group. In patients with localized disease, non-significant differences in cancer and cancer-free survival were found with hazard ratios of 1.31 and 1.29, respectively. Although new cancers occurred at similar rate, the cancer-free survival was significantly shorter in the 80% oxygen group, but this did not appear to explain the excess mortality in the 80% oxygen group.

    Full Text Available OBJECTIVE: Mohs micrographic surgery is a specialized surgical procedure used to treat skin cancer. The purpose of this study was to better understand the profile of the patients who underwent the procedure and to determine how histology might be related to complications and the number of stages required for complete removal. METHODS: The records of patients who underwent Mohs micrographic surgery from October 2008 to November 2013 at the Dermatology Division of the Hospital of the Campinas University were assessed. The variables included were gender, age, anatomical location, histology, number of stages required and complications. RESULTS: Contingency tables were used to compare the number of stages with the histological diagnosis. The analysis showed that patients with superficial basal cell carcinoma were 9.03 times more likely to require more than one stage. A comparison between complications and histological diagnosis showed that patients with superficial basal cell carcinoma were 6.5 times more likely to experience complications. CONCLUSION: Although superficial basal cell carcinoma is typically thought to represent a less-aggressive variant of these tumors, its propensity for demonstrating “skip areas” and clinically indistinct borders make it a challenge to treat. Its particular nature may result in the higher number of surgery stages required, which may, as a consequence, result in more complications, including recurrence. Recurrence likely occurs due to the inadequate excision of the tumors despite their clear margins. Further research on this subtype of basal cell carcinoma is needed to optimize treatments and decrease morbidity.

    The rs9939609 single nucleotide polymorphism (SNP) in the fat mass and obesity-associated (FTO) gene is involved in obesity. Few studies have been conducted on patients who underwent bariatric surgery. The aim of this study was to evaluate the influence of FTO SNPs on body weight, body composition, and weight regain during a 60-mo follow-up period after bariatric surgery. The rs9939609 was genotyped in 146 individuals using a real-time polymerase chain reaction TaqMan assay. Data for lifestyle, comorbidities, body weight, body mass index (BMI), excess weight loss (EWL), and body composition were obtained before and 6, 12, 18, 24, 36, 48, and 60 mo after surgery. Data were analyzed by comparing two groups of patients according to rs9939609 FTO gene polymorphism. Mixed-regression models were constructed to evaluate the dynamics of body weight, BMI, and EWL over time in female patients. No differences were observed between the groups during the first 24 mo after surgery. After 36, 48, and 60 mo, body weight, fat mass, and BMI were higher, whereas fat-free mass and EWL were lower in the FTO-SNP patient group. Weight regain was more frequent and occurred sooner in the FTO-SNP group. There is a different evolution of weight loss in obese carriers of the FTO gene variant rs9939609 after bariatric surgery. However, this pattern was evident at only 2 y postbariatric surgery, inducing a lower proportion of surgery success and a greater and earlier weight regain. Copyright © 2015 Elsevier Inc.

    To recognize and document the small bowel reactions following major abdominal surgery is an important key for a correct diagnosis. Usually, plain abdominal radiography is the initial imaging examination requested in the immediate postoperative period, whereas gastrointestinal contrast studies are used to look for specific complications. In some countries, especially in Europe, sonography is widely employed to evaluate any acute affection of the abdomen. CT is commonly used to assess postoperative abdominal complications; in our institution also CT enteroclysis is often performed, to provide additional important informations. Radiologist should be able to diagnose less common types of obstruction, such as afferent loop, closed loop, strangulating obstruction as well as internal hernia. This knowledge may assume a critical importance for surgeons to decide on therapy. In this article, we focus our attention on the imaging (particularly CT) in small bowel complications following abdominal surgery.

    We hypothesised that intraoperative non-depolarising neuromuscular blocking agent (NMBA) dose is associated with 30-day hospital readmission. Data from 13,122 adult patients who underwent abdominal surgery under general anaesthesia at a tertiary care hospital were analysed by multivariable regression, to examine the effects of intraoperatively administered NMBA dose on 30-day readmission (primary endpoint), hospital length of stay, and hospital costs. Clinicians used cisatracurium (mean dose [SD] 0.19 mg kg-1 [0.12]), rocuronium (0.83 mg kg-1 [0.53]) and vecuronium (0.14 mg kg-1 [0.07]). Intraoperative administration of NMBAs was dose-dependently associated with higher risk of 30-day hospital readmission (adjusted odds ratio 1.89 [95% Confidence Interval (CI) 1.26-2.84] for 5th quintile vs 1st quintile; P for trend: Psurgery) significantly modified the risk (interaction term: aOR 1.31 [95% CI 1.05-1.63], P=0.02), and the adjusted odds of readmission in patients undergoing ambulatory surgical procedures who received high-dose NMBAs vs low-dose NMBAs amounted to 2.61 [95% CI 1.11-6.17], P for trend: Phigh doses of NMBAs given during abdominal surgery was associated with an increased risk of 30-day readmission, particularly in patients undergoing ambulatory surgery.

    Patients with liver cirrhosis have an increased risk of postoperative mortality. In addition, cirrhotic patients per se have a reduced life expectancy. Little is known about the combined effect of these factors on long-term outcomes after surgery. We thus evaluated early -and long-term survival in patients with cirrhosis who underwent abdominal surgery. We evaluated 30- and 90-day mortality as well as long-term survival after 212 general surgical procedures performed in 194 patients with liver cirrhosis. Risk factors for early and late mortality were assessed by uni- and multivariate methods. To avoid multicollinearity of data, different models (Child Turcotte Pugh [CTP], model for end-stage liver disease [MELD], or American Society of Anesthesiologists [ASA] score) were used in multivariate analysis. The 30- and 90-day mortality rates were 20% and 30%, respectively. CTP, MELD, and ASA were all independently associated with 30- and 90-day mortality. Although emergency operations and intraoperative transfusions independently influenced 30-day mortality, 90-day mortality also was influenced by the extent of the procedure and thrombocytopenia. Survival after surgery (n = 180) was 54% after one and 25% after 5 years (median survival 1.24 years). Long-term survival was independently influenced by CTP, MELD, ASA, hyponatremia, emergency operations, thrombocytopenia, and underlying malignancies. Survival in patients discharged after surgery (n = 140) was 69% after 1 and 33% after 5 years (median survival 2.8 years). Survival after discharge was independently influenced by MELD, CTP, hyponatremia, underlying malignant disease, and (partially) by serum creatinine. The inclusion of serum sodium into MELD scores did not further facilitate prediction of early and late mortality. A high postoperative mortality as well as a strongly reduced survival even after hospital discharge contribute to the very poor life expectancy in patients with liver cirrhosis requiring general

    There are little data currently available to guide surgical decision making regarding emergent surgical interventions in leukopenic patients. The purpose of this study was to investigate the impact of leukopenia among patients undergoing emergency abdominal operations to better guide preoperative decision making.

Patients were stratified by preoperative white blood cell (WBC) count (leukopenia and mortality, taking into account the robust array of patient-related factors. Of the 20,443 patients who met study criteria, 2,057 (8.2%) were leukopenic (WBC leukopenia compared with patients with a normal preoperative WBC count. Only 46.0% (n = 947) of patients with leukopenia before surgery were able to avoid major morbidity or mortality compared with 69.4% (n = 15,974) of patients with a normal preoperative WBC count (p leukopenia was maintained as a significant predictor of mortality. Although leukopenia remains associated with mortality in patients undergoing emergent laparotomy despite adjustment for other patient-related factors, it is not necessarily prohibitive. Understanding the risk of complications and mortality associated with these procedures is pertinent for preoperative clinical decision making. Prognostic and epidemiologic study, level III.

    Purpose: To compare the diagnostic value of dual-phase multidetector-row CT (MDCT) and MR imaging with dual-phase three-dimensional MR angiography (MRA) in the prediction of vascular involvement and resectability of pancreatic ductal adenocarcinoma. Methods and materials: 116 patients with proven pancreatic adenocarcinoma underwent both MDCT and combined MR imaging prior to surgery. Of 116 patients, 56 who underwent surgery were included. Two radiologists independently attempt to assess detectability, vascular involvement and resectability of pancreatic adenocarcinoma on both images. Results were compared with surgical findings and statistical analysis was performed. Results: MDCT detected pancreatic mass in 45 of 56 patients (80.3%) and MR imaging in 44 patients (78.6%). In assessment of vascular involvement, sensitivities and specificities of MDCT were 61% and 96% on a vessel-by-vessel basis, respectively. Those of MR imaging were 57% and 98%, respectively. In determining resectability, sensitivities and specificities of MDCT were 90% and 65%, respectively. Those of MR imaging were 90% and 41%, respectively. There was no statistical difference in detecting tumor, assessing vascular involvement and determining resectability between MDCT and MR imaging (p = 0.5). Conclusion: MDCT and MR imaging with MRA demonstrated an equal ability in detection, predicting vascular involvement, and determining resectability for a pancreatic ductal adenocarcinoma.

    Over the last decades longevity has increased significantly, with more octogenarians undergoing surgery. Here, we assess surgical outcomes after major abdominal surgery in octogenarians. Observational cohort of 874 patients undergoing major abdominal elective surgery between January 2009 and March 2014. Seventy-six octogenarians were propensity matched to 76 younger patients, corrected for sex, body mass index, American Society of Anesthesiologists classification, comorbidity, indication, and type of surgery. Minor complications were more prevalent in octogenarians (P = .01) and consisted mainly of respiratory complications; progressing to respiratory insufficiency requiring intubation in 28.6%. Preoperative weight loss (odds ratio 3 [1.1 to 8.3]) and upper gastrointestinal surgery (odds ratio 11 [2 to 60]) were associated with minor complications. Octogenarians are at increased risk of minor complications after major abdominal surgery. Major complication rates were similar, indicating the importance of preoperative assessment and standardized surgical techniques. Taking into account preoperative morbidities and type of surgery and techniques. Implementation of quality control algorithms may further improve outcomes in octogenarians.

    Emergency abdominal surgery results in a high rate of post-operative complications and death. There are limited data describing the emergency surgical population in details. We aimed to give a detailed analyses of complications and mortality in a consecutive group of patients undergoing acute abdominal surgery over a 4-year period. This observational study was conducted between 2009 and 2013 at Copenhagen University Hospital Herlev, Denmark. All patients scheduled for emergency laparotomy or laparoscopy were included. Pre-, intra-, and post-operative data were collected from medical records. Complications were registered according to the Clavien-Dindo classification. Cox regression analysis was performed to identify risk factors for mortality. A total of 4,346 patients underwent emergency surgery, of whom 14 % had surgical complications and 23 % medical complications. The overall 30-day mortality was 8 % with 50 % of those in this group over 80 years of age. The 30-day mortality rates were 0.8 % (95 % CI 0.5-1.1) and 17 % (95 % CI 15.5-18.9), respectively, for the laparoscopy and the laparotomy groups. The overall death rate within 24 h of surgery was 21 %. Several risk factors for 30- and 90-day mortality were identified: age, ASA ≥3 (American Society of Anaesthesiologists physical status classification), performance score (Zubroed/WHOclassification), cirrhosis of the liver, chronic nephropathy, several medical conditions, and malignancy. Almost one in five patients died after emergency laparotomy, of whom one in five died within 24 h of surgery. Predictors for poor outcome were identified.

    Laparoscopic surgery has generated a revolution in operative medicine during the past few decades. Although strongly criticized during its early years, minimization of surgical trauma and the benefits of minimization to the patient have been brought to our attention through the efforts and vision of a few pioneers in the recent history of medicine. The German gynecologist Kurt Semm (1927-2003) transformed the use of laparoscopy for diagnostic purposes into a modern therapeutic surgical concept, having performed the first laparoscopic appendectomy, inspiring Erich Mühe and many other surgeons around the world to perform a wide spectrum of procedures by minimally invasive means. Laparoscopic cholecystectomy soon became the gold standard, and various laparoscopic procedures are now preferred over open approaches, in the light of emerging evidence that demonstrates less operative stress, reduced pain, and shorter convalescence. Natural orifice transluminal endoscopic surgery (NOTES) and single-incision laparoscopic surgery (SILS) may be considered further steps toward minimization of surgical trauma, although these methods have not yet been standardized. Laparoscopic surgery with the use of a robotic platform constitutes a promising field of investigation. New technologies are to be considered under the prism of the history of surgery; they seem to be a step toward further minimization of surgical trauma, but not definite therapeutic modalities. Patient safety and medical ethics must be the cornerstone of future investigation and implementation of new techniques.

    Enhanced recovery after surgery (ERAS) is a well-established pathway of perioperative care in surgery in an increasing number of specialties. To implement protocols and maintain high levels of compliance, continued support from care providers and patients is vital. This survey aimed to assess the perceptions of care providers and patients of the relevance and importance of the ERAS targets and strategies. Pre- and post-operative surveys were completed by patients who underwent major hepatic, colorectal, or oesophagogastric surgery in three major centers in Scotland, Norway, and The Netherlands. Anonymous web-based and article surveys were also sent to surgeons, anesthetists, and nurses experienced in delivering enhanced recovery protocols. Each questionnaire asked the responder to rate a selection of enhanced recovery targets and strategies in terms of perceived importance. One hundred nine patients and 57 care providers completed the preoperative survey. Overall, both patients and care providers rated the majority of items as important and supported ERAS principles. Freedom from nausea (median, 10; interquartile range [IQR], 8-10) and pain at rest (median, 10; IQR, 8-10) were the care components rated the highest by both patients and care providers. Early return of bowel function (median, 7; IQR, 5-8) and avoiding preanesthetic sedation (median, 6; IQR, 3.75-8) were scored the lowest by care providers. ERAS principles are supported by both patients and care providers. This is important when attempting to implement and maintain an ERAS program. Controversies still remain regarding the relative importance of individual ERAS components. Copyright © 2015 Elsevier Inc. All rights reserved.

  4. Nutrition management in enhanced recovery after abdominal pancreatic surgery.

    Márquez Mesa, Elena; Baz Figueroa, Caleb; Suárez Llanos, José Pablo; Sanz Pereda, Pablo; Barrera Gómez, Manuel Ángel

    Multimodal rehabilitation programs are perioperative standardized strategies with the objective of improving patient recovery, and decreasing morbidity, hospital stay and health cost. The nutritional aspect is an essential component of multimodal rehabilitation programs and therefore nutritional screening is recommended prior to hospital admission, avoiding pre-surgical fasting, with oral carbohydrate overload and early initiation of oral intake after surgery. However, there are no standardized protocols of diet progression after pancreatic surgery. A systematic review was been performed of papers published between 2006 and 2016, describing different nutritional strategies after pancreatic surgery and its possible implications in postoperative outcome. The studies evaluated are very heterogeneous, so conclusive results could not be drawn on the diet protocol to be implemented, its influence on clinical variables, or the need for concomitant artificial nutrition.

    An abdominal advancement flap (AAF) is a flap that pulls the elevated abdominal skin up, creating the shape of the inferior portion of the breast by making a neo-inframammary fold. We used an AAF combined with volume displacement techniques to fill the defect left after breast-conserving surgery (BCS). Forty-one small- to medium-sized breast patients whose resection area included the lower portion of the breast underwent this procedure from October 2010 to December 2014. We evaluated efficacy of this procedure. The excision volume ranged from 10 to 35 %. Complications after surgery were observed in two patients (partial necrosis of the nipple-areola complex and partial necrosis of the breast skin in one patient each). There was no fat necrosis of the flap in any of the patients. The cosmetic results were found to be excellent in 7 cases, good in 23, fair in 9 and poor in 2. In 11 cases with an unacceptable outcome, 9 cases were in the inner portion. In patients with the tumor in the inner portion, the proportion of unacceptable cases was 50 %. In the cases other than the inner portion, the proportion of unacceptable cases was 8.7 % (p breasts, unacceptable cases were more frequently observed (p breast, except in cases where the tumors is located in the inner potion.

    CONCLUSION: Surgeons and cardiologists should be aware of this cerebrovascular complication secondary to PFO following major reconstructive surgery such as microvascular breast reconstruction. It also serves to challenge microvascular surgeons to reconsider routine use of central venous pressure lines in free flap patients who might otherwise have good peripheral vessels for postoperative fluid and antibiotic administration.

    Endometriosis is a complex disease primarily affecting women of reproductive age worldwide. The management goals are to improve the quality of life (QoL), alleviate the symptoms and prevent severe disease. This prospective cohort study was to assess the QoL in women with endometriosis that underwent primary surgery. A pre- and post-operative questionnaire via ED-5Q and general VAS score used for the evaluation for endometrial-like pain such as dysmenorrhoea and dyspareunia. A total of 280 patients underwent intervention; 224 laparoscopically and 56 via laparotomy mostly with stage II disease with ovarian endometriomas. Improvements in dysmenorrhoea pain scores from 5.7 to 4.15 and dyspareunia from 4.05 to 2.17 (p <.001) were observed. The Self Rate Assessment was improved; 6.66-4.68 post-operatively (p < .05). In EQ-5 D Index, the anxiety and activities outcomes showed a significant worsening post-intervention. There was no correlation between the stage of disease and endometrial pain; (p = .289), method of intervention (p = .290) and usage of post-operative hormonal therapy (p = .632). This study concluded that surgical treatment improved the QoL with added hormonal therapy post-intervention, despite not reaching statistical significance, showed a promising result. Impact statement Surgical intervention does improve the QoL for women with endometriosis however post interventional hormonal therapy is remain inconclusive.

    Blood potassium levels were very important during perioperative management of patients undergoing abdominal surgery. According to various worldwide studies on the causes of hypokalemia and fast-track surgeries, prehospital hypokalemia was ignored. The aim of this study to construct a prevention and control system of hypokalemia through proper clinical pathways and investigate the effects in terms of fast postoperative recovery of patients undergoing open abdominal surgery. A total of 104 patients were randomized to an observation group or a control group. The prevention and control system of hypokalemia was constructed; it was composed of 3 major modules: blood potassium monitoring, etiologic intervention, and treatment of hypokalemia. In the observation group, blood was sampled at scheduled time points (the blood potassium monitoring module) and interventions involved the preadmission and pre- and postoperative periods (etiologic intervention module). In the control group, blood sampling was delayed until after admission (blood potassium monitoring module) and interventions were only performed during the pre- and postoperative periods (etiologic intervention module). In terms of blood potassium, indices regarding gastrointestinal motility and postoperative complications were compared. The severity of hypokalemia, postoperative defecation time, arrhythmia, fatigue syndrome, and urine retention differed statistically between the 2 groups (P control system of hypokalemia with the starting point being before admission was more effective and allows early prevention, detection, correction, surgery, and recovery of patients undergoing open abdominal surgeries and also could be used in other specialized nursing fields.

  12. Perioperative Nutrition in Abdominal Surgery: Recommendations and Reality

    Full Text Available Introduction. Preoperative malnutrition is a major risk factor for increased postoperative morbidity and mortality. Definition and diagnosis of malnutrition and its treatment is still subject for controversy. Furthermore, practical implementation of nutrition-related guidelines is unknown. Methods. A review of the available literature and of current guidelines on perioperative nutrition was conducted. We focused on nutritional screening and perioperative nutrition in patients undergoing digestive surgery, and we assessed translation of recent guidelines in clinical practice. Results and Conclusions. Malnutrition is a well-recognized risk factor for poor postoperative outcome. The prevalence of malnutrition depends largely on its definition; about 40% of patients undergoing major surgery fulfil current diagnostic criteria of being at nutritional risk. The Nutritional Risk Score is a pragmatic and validated tool to identify patients who should benefit from nutritional support. Adequate nutritional intervention entails reduced (infectious complications, hospital stay, and costs. Preoperative oral supplementation of a minimum of five days is preferable; depending on the patient and the type of surgery, immune-enhancing formulas are recommended. However, surgeons' compliance with evidence-based guidelines remains poor and efforts are necessary to implement routine nutritional screening and nutritional support.

    Despite recent advances in the treatment of advanced gastric carcinomas, no satisfactory outcomes are available because of micrometastases and free-floating carcinoma cells already existing in the peritoneal cavity. From 1990, we started using intraperitoneal hyperthermo-chemo-perfusion (IHCP) to prevent and to treat peritoneal metastasis after surgical resection of stomach cancer. We analyzed 103 serosa-invasive gastric carcinoma patients who underwent surgical resection between 1990 and 1995. Fifty-two patients who received surgery plus IHCP were compared with 51 patients who underwent surgery only, as controls. IHCP was administered for 2 h with an automatic IHCP device (closed-circuit system) just after surgical resection, with the patient under hypothermic general anesthesia (32.4 degrees C-34.0 degrees C). As perfusate, we used 1.5% peritoneal dialysis solution mixed with 10 micrograms/ml of mitomycin-C (MMC), warmed at an inflow temperature of over 44 degrees C. The overall 5-year survival rate (5-YSR) of the 103 patients was 29.97%. The 5-YSR was higher in the IHCP group than in the control group, at 32.7% and 27.1%, respectively, but this difference was not significant. However, in the 65 serosa-invasive gastric carcinoma patients (excluding those in stage IV) the 5-YSR was significantly higher (P = 0.0379) in the IHCP group than in the control group, at 58.6% and 44.4%, respectively. On multivariate analysis of all 103 patients, depth of tumor invasion and lymph node metastasis were significant factors for survival, whereas significant factors on univariate analysis, such as combined operation, distant metastasis, and peritoneal metastasis, were not significant. The most common recurrence patterns were loco-regional in the IHCP group and peritoneal in the control group. Complete cytoreductive surgery plus IHCP is effective to prevent and to treat peritoneal metastasis, and it should lead to long-term survival for serosa-invasive gastric carcinoma patients

    Uterine leiomyosarcoma (LMS) in some cases may disseminate through the abdominal cavity, without extra-abdominal spreading, determining a condition of abdominal sarcomatosis, which represents a peculiar situation. Only radical surgical removal offers a chance of long-term survival in such cases of LMS. Here we describe a case of diffuse abdominal sarcomatosis from uterine LMS in a 51-year-old perimenopausal woman who underwent laparoscopic radical hysterectomy, bilateral salpingo-oophorectomy, total pelvic peritonectomy, pelvic lymphadenectomy to the mesenteric inferior artery, and omentectomy. Then, given the high probability of disease recurrence, the patient underwent a close follow-up consisting of positron emission tomography (PET)/computed tomography every 3 months and diagnostic (and if necessary operative) laparoscopy every 6 months. To date, the patient had 11 laparoscopies; 5 of them were preceded by a PET indicative of the presence of disease with high metabolic activity, which was confirmed at surgery and each time completely removed laparoscopically with no evidence of residual disease. To date, 5 years from diagnosis the patient is alive and continues her follow-up. Our report brings to light the ability of laparoscopic surgery to obtain disease control in a case of LMS with abdominal dissemination. Moreover, laparoscopic surgery, as demonstrated in our case, may have an important role in the close follow-up of the disease and allow a timely and early radical surgical approach of relapses before they become extremely large and difficult to remove radically.

    Blunt abdominal traumas are common. We retrospectively reviewed the medical records of 49 patients with blunt abdominal trauma who underwent surgery at the General Hospital of National Reference of N'Djamena, Chad over a period of 5 years. Epidemiological, clinical and therapeutic parameters of patients were studied. The study included 42 men and 7 women, mean age 21.3 years. The causes of blunt abdominal traumas were: road traffic accidents in 61.2% of cases; wall collapses (14.3%); assaults (8.2%). Blunt abdominal traumas were more frequent in August (14.28%) and October (16.32%). The waiting time for admission in hospital was 6-12h in 43% of cases. At discharge, wounded patients used private car in 85.7% of cases. Clinically, patients were often hemodynamically stable (55.1%). Medical imaging was dominated by direct radiography of the abdomen (57.1%). The most observed lesions were those located only in the small intestine (16.32%) or related to that of the bladder (8.16%) and spleen (2.04%). Laparotomy was negative in 6.12% of cases. Morbidity (12.2%) was dominated by abdominal wall abscess. Mortality rate was 6.1%. Road traffic accidents are the leading cause of blunt abdominal traumas. It is important to minimize delays in diagnosis, and treatment. Road safety measures should be implemented to prevent accidents.

    Electrical impedance tomography (EIT) of the lungs facilitates visualization of ventilation distribution during mechanical ventilation. Its intraoperative use could provide the basis for individual optimization of ventilator settings, especially in patients at risk for ventilation-perfusion mismatch and impaired gas exchange, such as patients undergoing major open upper abdominal surgery. EIT throughout major open upper abdominal surgery could encounter difficulties in belt positioning and signal quality. Thus, we conducted a pilot-study and tested whether EIT is feasible in patients undergoing major open upper abdominal surgery. Following institutional review board's approval and written informed consent, we included patients scheduled for major open upper abdominal surgery of at least 3 hours duration. EIT measurements were conducted prior to intubation, at the time of skin incision, then hourly during surgery until shortly prior to extubation and after extubation. Number of successful intraoperative EIT measurements and reasons for failures were documented. From the valid measurements, a functional EIT image of changes in tidal impedance was generated for every time point. Regions of interest were defined as horizontal halves of the picture. Monitoring of ventilation distribution was assessed using the center of ventilation index, and also using the total and dorsal ventilated lung area. All parameter values prior to and post intubation as well as extubation were compared. A p abdominal surgery lasting 4-13 hours were planned in 14 patients. The electrode belt was attached between the 2(nd) and 4(th) intercostal space. Consecutive valid measurements could be acquired in 13 patients (93%). 111 intraoperative measurements could be retrieved as planned (93%). Main obstacle was the contact of skin electrodes. Despite the high belt position, distribution of tidal volume showed a significant shift of ventilation towards ventral lung regions after intubation. This

    The number of citations a scientific article receives provides a good indication of its impact within any given field. This bibliometric analysis aimed to identify the 100 most cited articles in Emergency Abdominal Surgery (EAS), to highlight key areas of interest and identify those that have most significantly shaped contemporary clinical practice in this newly evolving surgical specialty. This is of increasing relevance as concerns grow regarding the variable and suboptimal outcomes in Emergency General Surgery. The Thomson Reuters Web of Science database was used to search using the terms [Emergency AND Abdom* AND Surg*] to identify all English language, full manuscripts. Results were ranked according to citation number. The top 100 articles were further analysed by subject, author, journal, year of publication, institution, and country of origin. The median (range) citation number of the top 100 out of 7433 eligible papers was 131 (1569-97). The most cited paper (by Goldman et al., Massachusetts General Hospital, New England Journal of Medicine; 1569 citations) focused on cardiac risk stratification in non-cardiac surgery. The Journal of Trauma, Injury, Infection and Critical Care published the most papers and received most citations (n = 19; 2954 citations. The majority of papers were published by centres in the USA (n = 52; 9422 citations), followed by the UK (n = 13; 1816 citations). The most common topics of publication concerned abdominal aneurysm management (n = 26) and emergency gastrointestinal surgery (n = 26). Vascular surgery, risk assessment and gastrointestinal surgery were the areas of focus for 59% of the contemporary most cited emergency abdominal surgery manuscripts. By providing the most influential references this work serves as a guide to what makes a citable emergency surgery paper. Crown Copyright © 2016. Published by Elsevier Ltd. All rights reserved.

    "Candy cane" syndrome (a blind afferent Roux limb at the gastrojejunostomy) has been implicated as a cause of abdominal pain, nausea, and emesis after Roux-n-Y gastric bypass (RYGB) but remains poorly described. To report that "candy cane" syndrome is real and can be treated effectively with revisional bariatric surgery SETTING: All patients underwent "candy cane" resection at University Hospitals of Cleveland. All patients who underwent resection of the "candy cane" between January 2011 and July 2015 were included. All had preoperative workup to identify "candy cane" syndrome. Demographic data; pre-, peri-, and postoperative symptoms; data regarding hospitalization; and postoperative weight loss were assessed through retrospective chart review. Data were analyzed using Student's t test and χ 2 analysis where appropriate. Nineteen patients had resection of the "candy cane" (94% female, mean age 50±11 yr), within 3 to 11 years after initial RYGB. Primary presenting symptoms were epigastric abdominal pain (68%) and nausea/vomiting (32%), particularly with fibrous foods and meats. On upper gastrointestinal study and endoscopy, the afferent blind limb was the most direct outlet from the gastrojejunostomy. Only patients with these preoperative findings were deemed to have "candy cane" syndrome. Eighteen (94%) cases were completed laparoscopically. Length of the "candy cane" ranged from 3 to 22 cm. Median length of stay was 1 day. After resection, 18 (94%) patients had complete resolution of their symptoms (PCandy cane" syndrome is a real phenomenon that can be managed safely with excellent outcomes with resection of the blind afferent limb. A thorough diagnostic workup is paramount to proper identification of this syndrome. Surgeons should minimize the size of the blind afferent loop left at the time of initial RYGB.

    During robot-assisted radical prostatectomy (RARP), the prostate may be approached extraperiteoneally (extraperitoneal robot-assisted radical prostatectomy [eRARP]) or transperitoneally (transperitoneal robot-assisted radical prostatectomy [tRARP]). The former avoids the abdominal cavity, which might be of benefit in patients who have had prior abdominal or pelvic surgery (PAPS). Our objective was to compare the outcomes of patients with PAPS undergoing either technique. A retrospective review of patients treated with RARP from July 1, 2003 to December 31, 2014 with a minimum follow-up of 3 months was undertaken. Of 2927 patients, 620 were identified as having undergone RARP (without concomitant unrelated procedures) and PAPS (excluding patients with prior inguinal hernia repair with mesh or unclear surgical histories) for prostate adenocarcinoma without prior pelvic radiotherapy. Of these, 340 patients underwent eRARP and 280 patients underwent tRARP. Patients in the eRARP group were younger (61.04 years vs 62.32, p = 0.02), had a higher body mass index (29.65 vs 28.98, p = 0.09), lower American Society of Anesthesiologists scores (p = 0.03), and lower D'Amico risk classification disease (p 2 PAPS. On univariate analysis, the eRARP group had lower operative time (188.96 minutes vs 197.92 minutes, p = 0.003), extensive lysis of adhesions (0.9% vs 14.3%, p surgeries. A lower incidence of gastrointestinal complications and a shorter length of stay were noted in the extraperitoneal cohort.

    A best evidence topic in vascular surgery was written according to a structured protocol. The question addressed was whether the use of intraoperative cell-salvage (ICS) leads to negative outcomes in patients undergoing elective abdominal aortic surgery? Altogether 305 papers were found using the reported search, of which 10 were judged to represent the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers were tabulated. None of the 10 papers included in the analysis demonstrated that ICS use led to significantly higher incidence of cardiac or septic postoperative complications. Similarly, length of intensive treatment unit (ITU) or hospital stay and mortality in elective abdominal aortic surgery were not adversely affected. Indeed two trials actually show a significantly shorter hospital stay after ICS use, one a shorter ITU stay and another suggests lower rates of chest sepsis. Based on these papers, we concluded that the use of ICS does not cause increased morbidity or mortality when compared to standard practise of transfusion of allogenic blood, and may actually improve some clinical outcomes. As abdominal aortic surgery inevitably causes significant intraoperative blood loss, in the range of 661-3755 ml as described in the papers detailed in this review, ICS is a useful and safe strategy to minimise use of allogenic blood.

    Full Text Available Abstract Background Pre-marketing clinical studies of tegaserod suggested an increased risk of abdominal surgery, particularly cholecystectomy. We sought to quantify the association between tegaserod use and the occurrence of abdominal or pelvic surgery, including cholecystectomy. Methods This cohort study was conducted within an insured population. Tegaserod initiators and similar persons who did not initiate tegaserod were followed for up to six months for the occurrence of abdominal or pelvic surgery. Surgical procedures were identified from health insurance claims validated by review of medical records. The incidence of confirmed outcomes was compared using both as-matched and as-treated analyses. Results Among 2,762 tegaserod initiators, there were 94 abdominal or pelvic surgeries (36 gallbladder: among 2,762 comparators there were 134 abdominal or pelvic surgeries (37 gallbladder (hazard ratio HR] = 0.70, 95% confidence interval [C.I.] = 0.54-0.91 overall, HR = 0.98, 95% C.I. = 0.62-1.55 for gallbladder. Current tegaserod exposure compared to nonexposure was associated with a rate ratio [RR] of 0.68 (95% C.I. = 0.48-0.95 overall, while the RR was 0.99 (95% C.I. = 0.56-1.77 for gallbladder surgery. Conclusions In this study, tegaserod use was not found to increase the risk of abdominal or pelvic surgery nor the specific subset of gallbladder surgery.

    Intraoperative hypothermia during both open and laparoscopic abdominal surgery may be associated with adverse events. For laparoscopic abdominal surgery, the use of heated insufflation systems for establishing pneumoperitoneum has been described to prevent hypothermia. Humidification of the insufflated gas is also possible. Past studies have shown inconclusive results with regards to maintenance of core temperature and reduction of postoperative pain and recovery times. To determine the effect of heated gas insufflation on patient outcomes following minimally invasive abdominal surgery. The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE (PubMed), EMBASE, International Pharmaceutical Abstracts (IPA), Web of Science, Scopus, www.clinicaltrials.gov and the National Research Register were searched (1956 to 14 June 2010). Grey literature and cross-references were also searched. Searches were limited to human studies without language restriction. All included studies were randomized trials comparing heated (with or without humidification) gas insufflation with cold gas insufflation in adult and pediatric populations undergoing minimally invasive abdominal procedures. Study quality was assessed in regards to relevance, design, sequence generation, allocation concealment, blinding, possibility of incomplete data and selective reporting. The selection of studies for the review was done independently by two authors, with any disagreement resolved in consensus with a third co-author. Screening of eligible studies, data extraction and methodological quality assessment of the trials were performed by the authors. Data from eligible studies were collected using data sheets. Results were presented using mean differences for continuous outcomes and relative risks with 95% confidence intervals for dichotomous outcomes. The estimated effects were calculated using the latest version of RevMan software. Publication bias was taken into

    Ventral incisional hernias (VIH) develop in up to 20% of patients after abdominal surgery. No widely applicable preoperative risk-assessment tool exists. We aimed to develop and validate a risk-assessment tool to predict VIH after abdominal surgery. A prospective study of all patients undergoing abdominal surgery was conducted at a single institution from 2008 to 2010. Variables were defined in accordance with the National Surgical Quality Improvement Project, and VIH was determined through clinical and radiographic evaluation. A multivariate Cox proportional hazard model was built from a development cohort (2008 to 2009) to identify predictors of VIH. The HERNIAscore was created by converting the hazards ratios (HR) to points. The predictive accuracy was assessed on the validation cohort (2010) using a receiver operator characteristic curve and calculating the area under the curve (AUC). Of 625 patients followed for a median of 41 months (range 0.3 to 64 months), 93 (13.9%) developed a VIH. The training cohort (n = 428, VIH = 70, 16.4%) identified 4 independent predictors: laparotomy (HR 4.77, 95% CI 2.61 to 8.70) or hand-assisted laparoscopy (HAL, HR 4.00, 95% CI 2.08 to 7.70), COPD (HR 2.35; 95% CI 1.44 to 3.83), and BMI ≥ 25 kg/m(2) (HR1.74; 95% CI 1.04 to 2.91). Factors that were not predictive included age, sex, American Society of Anesthesiologists (ASA) score, albumin, immunosuppression, previous surgery, and suture material or technique. The predictive score had an AUC = 0.77 (95% CI 0.68 to 0.86) using the validation cohort (n = 197, VIH = 23, 11.6%). Using the HERNIAscore: HERNIAscore = 4(∗)Laparotomy+3(∗)HAL+1(∗)COPD+1(∗) BMI ≥ 25, 3 classes stratified the risk of VIH: class I (0 to 3 points),5.2%; class II (4 to 5 points),19.6%; and class III (6 points), 55.0%. The HERNIAscore accurately identifies patients at increased risk for VIH. Although external validation is needed, this provides a starting point to counsel patients and guide

    Conclusion: Epidural, PCIA and opioid infusions are used for pain relief after major abdominal surgeries at our hospital. Although there is limited drug availability, regular assessments and appropriate dose adjustments by acute pain management service (APMS and use of multimodal analgesia led to a high level of patient satisfaction. We recommend that feedback to the primary anesthesiologists by APMS is of utmost importance to enable improvement in practice.

    Full Text Available OBJECTIVES: The development of sepsis after abdominal surgery is associated with high morbidity and mortality. Due to inflammation, it may be difficult to diagnose infection when it occurs, but measurement of C-reactive protein could facilitate this diagnosis. In the present study, we evaluated the predictive value and time course of C-reactive protein in relation to outcome in patients admitted to the intensive care unit (ICU after abdominal surgery. METHODS: We included patients admitted to the ICU after abdominal surgery over a period of two years. The patients were divided into two groups according to their outcome: favorable (F; left the ICU alive, without modification of the antibiotic regimen and unfavorable (D; death in the ICU, surgical revision with or without modification of the antibiotic regimen or just modification of the regimen. We then compared the highest C-reactive protein level on the first day of admission between the two groups. RESULTS: A total of 308 patients were included: 86 patients had an unfavorable outcome (group D and 222 had a favorable outcome (group F. The groups were similar in terms of leukocytosis, neutrophilia, and platelet count. C-reactive protein was significantly higher at admission in group D and was the best predictor of an unfavorable outcome, with a sensitivity of 74% and a specificity of 72% for a threshold of 41 mg/L. No changes in C-reactive protein, as assessed based on the delta C-reactive protein, especially at days 4 and 5, were associated with a poor prognosis. CONCLUSIONS: A C-reactive protein cut-off of 41 mg/L during the first day of ICU admission after abdominal surgery was a predictor of an adverse outcome. However, no changes in the C-reactive protein concentration, especially by day 4 or 5, could identify patients at risk of death.

    Abdominal surgery in critically ill patients has high mortality, contributing to high US healthcare costs. This study sought to identify specific predictors of mortality in this population. Using the National Surgical Quality Improvement Program database 2006 to 2012, we identified 4,901 patients who were intubated for more than 48 hours before undergoing common abdominal procedures. Mortality and predictors of mortality were determined using chi-square and/or regression analysis. Overall 30-day mortality was 44.2% with increasing mortality for additional procedures performed. Ventilated patients with the following preoperative risk factors were 2 to 3 times as likely to die within 30 days of surgery: age greater than 65-years old, coma, preoperative international normalized ratio greater than 3.0, esophageal varices, and disseminated cancer. Mortality is significant in ventilated patients who undergo abdominal surgery and is especially high with advanced age, disseminated cancer, and complications of liver disease. Physicians should carefully discuss this with patients and/or family and consider palliative options when appropriate. Copyright © 2016 Elsevier Inc. All rights reserved.

    To assess the clinical and economical validity of glutamine dipeptide supplemented to parenteral nutrition (PN) in patients undergoing abdominal surgery. A meta-analysis of all the relevant randomized controlled trials (RCTs) was performed. The trials compared the standard PN and PN supplemented with glutamine dipeptide in abdominal surgery. RCTs were identified from the following electronic databases: the Cochrane Library, MEDLINE, EMBASE and ISI web of knowledge (SCI). The search was undertaken in April 2006. Literature references were checked by computer or hand at the same time. Clinical trials were extracted and evaluated by two reviewers independently. Statistical analysis was performed by RevMan4.2 software from Cochrane Collaboration. A P value of nitrogen balance (weighted mean difference (WMD = 8.35, 95% CI [2.98, 13.71], P = 0.002), decreasing postoperative infectious morbidity (OR = 0.24, 95% CI [0.06, 0.93], P = 0.04), shortening the length of hospital stay (WMD= -3.55, 95% CI [-5.26, -1.84], P nitrogen balance in patients undergoing abdominal surgery. Further high quality trials in children and severe patients are required, and mortality and hospital cost should be considered in future RCTs with sufficient size and rigorous design.

    Full Text Available Background:Postoperative pain is an important surgical problem. Recent studies in pain pathophysiology have led to the hypothesis that with perioperative administration of analgesics (pre-emptive analgesia it may be possible to prevent or reduce postoperative pain. This study was planned to investigate the efficacy of pre-emptive analgesia on postoperative pain after major gynecologic abdominal surgeries. Methods: In this prospective, double-blinded, randomized, and placebocontrolled trial, 60 ASA physical status I and II patients undergoing major abdominal gynecologic surgeries were randomized to receive 45 mL of bupivacaine 0.375% or 45mL of normal saline; 30 mL and 15 mL of the treatment solution was administered into the peritoneal cavity and incision, respectively, before wound closure. The pain score of the patients was evaluated by the visual analogue scale (VAS on awakening, and at 6, 12, and 24h after surgery. Time to first analgesia request and total analgesic requirements in the first 24h were recorded. Results: Pain scores were significantly higher in the placebo group than in the bupivacaine group on awakening (5.98±1.01 v.s 1.05±1.05; p<0.001, and at 6h after surgery (5.37±0.85 vs. 2.51±1.02; p<0.001.

    Chronic postsurgical pain (CPSP) is a common complication of surgery with high impact on quality of life. Peripheral and central sensitization caused by enhanced and prolonged afferent nociceptive input are considered important mechanisms for the development of CPSP. This case-control study investigated whether epidural analgesia is associated with a reduced incidence of CPSP after open abdominal surgery. Six months after surgery, Short-Form-36 Health Survey (SF-36) pain scores, possible predictors of chronic pain, and quality of life were assessed. Patients treated with epidural analgesia in combination with general anesthesia (epidural group, N = 51) were compared to patients undergoing matched surgical procedures receiving general anesthesia alone (GA-group, N = 50). Multivariate analysis was performed by logistic regression analysis. Twenty-six (25.7%) patients experienced chronic pain, 9 in the epidural group (17.6%), 17 in the GA-group (34%), crude odds ratio (OR) 0.42 (95% confidence interval (CI) 0.16 to 1.05). After adjustment for the most prominent predictors of CPSP, such as age, sex, pre-operative pain, and acute postoperative pain, the OR for chronic pain in the epidural group was 0.19 (95% CI 0.05 to 0.76). Patients with CPSP reported a significantly lower quality of life compared to patients without CPSP (SF-36 total score median (IQR) 39.2 (27.2 to 56.7) vs. 84.3 (69.9 to 92.5, P abdominal surgery.

    Radiooncological therapies are an integral part of the multimodal oncological treatment concepts in general and abdominal surgery. These include therapeutic approaches with a curative intention such as the neoadjuvant (pre-operative) radiotherapy of locoregionally advanced and/or N+ oesophageal and rectal cancer, definitive combined chemoradiotherapy of locally advanced, unresectable oesophageal cancer or oesophageal tumour lesions of the upper third, definitive radiotherapy of anal cancer (sphincter sparing) and pre- or post-operative radiotherapy of soft tissue sarcoma on the one hand. A yT0 stage achieved as characteristic of a curative effect by radiation in oesophageal and rectal cancer (omitting subsequent surgical intervention, naturally under clinical and imaging-based controls within short-term follow-up intervals) can be considered as a very interesting set-up with regard to its reasonable integration in daily clinical practice, which needs to be further and critically discussed. By integrating radiotherapy in interdisciplinary therapy concepts, improved tumour control and survival rates with clinically acceptable toxicity can be achieved. On the other hand, non-invasive, locally ablative radiooncological therapies such as extracranial stereotactic body radiotherapy constitute an effective and feasible treatment method for liver metastases in oligometastatic colorectal cancer or other tumour entities according to the decisions by the institutional tumour board, offering high local tumour control rates which can be part of multistep, multimodal procedures with curative intention. This review aims at providing an overview for the general and abdominal surgeon, outlining relevant radiooncological treatment aspects in the multimodal cancer therapy with a focus on the treatment of rectal, oesophageal and anal cancer as well as soft tissue sarcoma and hepatic metastases in oligometastatic colorectal cancer.

    The components separation technique (CST) is a widely described abdominal wall reconstructive technique. There have, however, been no UK reports of its use, prompting the present review. Between 2008 and 2012, 13 patients who underwent this procedure by a single plastic surgeon (C.M.M.) were retrospectively evaluated. The indications, operative details, and clinical outcomes were recorded. There were 7 women and 6 men in the series with a mean age of 53 years (range: 30-80). Patients were referred from a variety of specialties, often as a last resort. The commonest indication for CST was herniation following abdominal surgery. All operations except 1 were jointly performed with general surgeons (for bowel resection, stoma reversal, and hernia dissection). The operations lasted a mean of 5 hours (range: 3-8 hours). There were no major intra- and postoperative problems, except in 1 patient who developed intra-abdominal compartment syndrome, secondary to massive hemorrhage. All patients were satisfied with the cosmetic improvement in their abdominal contours. None of the patients have developed a clinical recurrence after a mean follow-up of 16 months (range: 3-38 months). The components separation technique is an effective method of treating large recalcitrant hernias but appears to be underutilized in the United Kingdom. The management of large abdominal wall defects requires a multidisciplinary approach, with input across a variety of specialities. Liaison with plastic surgery teams should be encouraged at an early stage and the CST should be more widely considered when presented with seemingly intractable abdominal wall defects.

  11. Intra-operative tissue oxygen tension is increased by local insufflation of humidified-warm CO2 during open abdominal surgery in a rat model.

    Directory of Open Access Journals (Sweden)

    Jean K Marshall

    Full Text Available Maintenance of high tissue oxygenation (PtO2 is recommended during surgery because PtO2 is highly predictive of surgical site infection and colonic anastomotic leakage. However, surgical site perfusion is often sub-optimal, creating an obstructive hurdle for traditional, systemically applied therapies to maintain or increase surgical site PtO2. This research tested the hypothesis that insufflation of humidified-warm CO2 into the abdominal cavity would increase sub-peritoneal PtO2 during open abdominal surgery.15 Wistar rats underwent laparotomy under general anesthesia. Three sets of randomized cross-over experiments were conducted in which the abdominal cavity was subjected to alternating exposure to 1 humidified-warm CO2 & ambient air; 2 humidified-warm CO2 & dry-cold CO2; and 3 dry-cold CO2 & ambient air. Sub-peritoneal PtO2 and tissue temperature were measured with a polarographic oxygen probe.Upon insufflation of humidified-warm CO2, PtO2 increased by 29.8 mmHg (SD 13.3; p<0.001, or 96.6% (SD 51.9, and tissue temperature by 3.0°C (SD 1.7 p<0.001, in comparison with exposure to ambient air. Smaller, but significant, increases in PtO2 were seen in experiments 2 and 3. Tissue temperature decreased upon exposure to dry-cold CO2 compared with ambient air (-1.4°C, SD 0.5, p = 0.001.In a rat model, insufflation of humidified-warm CO2 into the abdominal cavity during open abdominal surgery causes an immediate and potentially clinically significant increase in PtO2. The effect is an additive result of the delivery of CO2 and avoidance of evaporative cooling via the delivery of the CO2 gas humidified at body temperature.

    The use of histological degeneration scores in surgically-treated herniated lumbar discs is not common in clinical practice and its use has been primarily restricted to research. The objective of this study is to evaluate if there is an association between a higher grade of histological degeneration when compared with clinical or radiological parameters. Retrospective consecutive analysis of 122 patients who underwent single-segment lumbar disc herniation surgery. Clinical information was available on all patients, while the histological study and preoperative magnetic resonance imaging were also retrieved for 75 patients. Clinical variables included age, duration of symptoms, neurological deficits, or affected deep tendon reflex. The preoperative magnetic resonance imaging was evaluated using Modic and Pfirrmann scores for the affected segment by 2 independent observers. Histological degeneration was evaluated using Weiler's score; the presence of inflammatory infiltrates and neovascularization, not included in the score, were also studied. Correlation and chi-square tests were used to assess the association between histological variables and clinical or radiological variables. Interobserver agreement was also evaluated for the MRI variables using weighted kappa. No statistically significant correlation was found between histological variables (histological degeneration score, inflammatory infiltrates or neovascularization) and clinical or radiological variables. Interobserver agreement for radiological scores resulted in a kappa of 0.79 for the Pfirrmann scale and 0.65 for the Modic scale, both statistically significant. In our series of patients, we could not demonstrate any correlation between the degree of histological degeneration or the presence of inflammatory infiltrates when compared with radiological degeneration scales or clinical variables such as the patient's age or duration of symptoms.

    2016-01-01

    Objectives In this study, we examined whether (1) positive end-expiratory pressure (PEEP) has a protective effect on the risk of major postoperative respiratory complications in a cohort of patients undergoing major abdominal surgeries and craniotomies, and (2) the effect of PEEP is differed by surgery type. Background Protective mechanical ventilation with lower tidal volumes and PEEP reduces compounded postoperative complications after abdominal surgery. However, data regarding the use of intraoperative PEEP is conflicting. Methods In this observational study, we included 5915 major abdominal surgery patients and 5063 craniotomy patients. Analysis was performed using multivariable logistic regression. The primary outcome was a composite of major postoperative respiratory complications (respiratory failure, reintubation, pulmonary edema, and pneumonia) within 3 days of surgery. Results Within the entire study population (major abdominal surgeries and craniotomies), we found an association between application of PEEP ≥5cmH2O and a decreased risk of postoperative respiratory complications compared with PEEP 5cmH2O was associated with a significant lower odds of respiratory complications in patients undergoing major abdominal surgery (odds ratio 0.53, 95% confidence interval 0.39 – 0.72), effects that translated to deceased hospital length of stay [median hospital length of stay : 6 days (4–9 days), incidence rate ratios for each additional day: 0.91 (0.84 - 0.98)], whereas PEEP >5cmH2O was not significantly associated with reduced odds of respiratory complications or hospital length of stay in patients undergoing craniotomy. Conclusions The protective effects of PEEP are procedure specific with meaningful effects observed in patients undergoing major abdominal surgery. Our data suggest that default mechanical ventilator settings should include PEEP of 5–10cmH2O during major abdominal surgery. PMID:26496082

    Surgical site infections (SSI) following abdominal surgery are frequent and a major cause of postoperative morbidity and prolonged hospital stay. Besides antibiotic prophylaxis, antiseptic skin preparation is an important measure to prevent SSI. Here we prospectively analyzed the effectiveness of antiseptic skin preparation in a cohort of 93 patients undergoing laparotomy, with special emphasis on the umbilical region. The microflora of the umbilicus contained a large number of resident (mostly staphylococci species and corynebacteria) and transient germs (including enterococci species). Following antiseptic skin preparation, bacteria could still be cultured from 24.7% of the patients' umbilici. In case of postoperative SSI, only one of seven SSI was caused by the microorganism that was present in the umbilicus before and after skin preparation. Antiseptic skin preparation fails to completely eradicate the microflora of the umbilical region in one quarter of the patients. However, at least in abdominal surgery, the vast majority of SSI are caused by intra-abdominal contamination rather than the skin microflora.

  15. The association between frequent alcohol drinking and opioid consumption after abdominal surgery: A retrospective analysis.

    Directory of Open Access Journals (Sweden)

    Sheng-Chin Kao

    Full Text Available It is perceived that patients with a history of frequent alcohol consumption require more opioids for postoperative pain control and experience less postoperative nausea and vomiting than patients without such a history. However, there is scarce evidence supporting this notion. The aim of this study was to assess association between frequent alcohol consumption and opioid requirement for postoperative pain control and occurrence of postoperative nausea and vomiting.The medical records for 4143 patients using intravenous patient-control analgesia with opioids after abdominal surgery between January 2010 and September 2013 were obtained, and associations were sought between the cumulative opioid consumption (in intravenous morphine equivalence per body weight (mg/kg in the first 2 days after abdominal operation and several demographic and clinical variables by multiple regression analysis. The association between the occurrence of postoperative nausea and vomiting and several demographic and clinical variables was also sought by multiple logistic regression analysis.Frequent alcohol drinking, among other previously reported factors, was associated with increased opioid consumption for postoperative pain control (p < 0.001. The estimate effect of frequent alcohol drinking was 0.117 mg/kg. Frequent alcohol drinking was also associated with decreased risks of postoperative nausea (odds ratio = 0.59, p = 0.003 and vomiting (odds ratio = 0.49, p = 0.026.Frequent alcohol drinking was associated with increased opioid consumption for postoperative pain control and decreased risks of postoperative nausea and vomiting after abdominal surgery.

    Full Text Available Abstract Background To assess the construct validity and responsiveness of the PROMIS Physical Function v1.2 short form 8b (PROMIS-PF, and the PROMIS Ability to Participate in Social Roles and Activities v2.0 short form 8a (PROMIS-APS in postoperative recovery. Methods An observational pilot study was conducted in which 30 patients participated, undergoing various forms of abdominal surgery. Patients completed the PROMIS-PF and PROMIS-APS, the Short Form 36 Health Survey (SF-36 and the World Health Organization Disability Assessment Schedule 2.0 (WHODAS at several time points before and after surgery. The construct validity and responsiveness of the two PROMIS short forms were evaluated by testing pre-defined hypotheses and were considered adequate when at least 75% of the data was consistent with the hypotheses. Construct validity was evaluated by calculating Spearman correlations and the responsiveness by calculating effect sizes. Results 6/7 (85.7% of the results were consistent with the hypotheses supporting the construct validity of the PROMIS-PF. For the PROMIS-APS this was the case in 7/15 (46.7% of the results. For the PROMIS-PF, 6/7 (85.7% of the results were consistent with the hypotheses, supporting responsiveness. Regarding the responsiveness of the PROMIS-APS, only 7 out of 13 (53.8% of these results were consistent with the hypotheses. Conclusions This study supported the construct validity and the responsiveness of the PROMIS-PF v1.2 short form 8b for measuring recovery in abdominal surgery. Considering the major advantages of PROMIS, we recommend the use of the PROMIS-PF in abdominal surgery.

    To evaluate the results of the introduction of new measures to accelerate the postoperative recovery of patients undergoing elective abdominal surgery. We observed 162 patients and interviewed them on two distinct periods: the first between October to December 2009 (n = 81) comprised patients who underwent conventional perioperative monitoring (pre-intervention) and the second between March and May 2010 (n = 81), formed by a new group of patients, submitted to the new protocol of perioperative monitoring. Data collection in the two periods occurred without the knowledge of the professionals in the service. The variables were: indication for preoperative nutritional support, duration of fasting, post-operative volume of hydration, use of catheters and drains, length of stay and postoperative morbidity. when comparing the two periods we observed a decrease of 2.5 hours in the time of preoperative fasting (p = 0.0002) in the post-intervention group. As for the reintroduction of oral diet, there was no difference between the two periods (p = 0.0007). When considering the patients without postoperative complications, there was a significantly decreased length of stay (p = 0.001325). There was a reduction of approximately 50% in antibiotic use in the post-intervention group (p = 0.00001). The adoption of multidisciplinary perioperative measures is feasible within our reality, and although there was no statistically significant changes in the present study, it may improve morbidity and reduce length of stay in general surgery.

    Purpose: To identify the prognostic role of adjuvant abdominal radiation therapy (RT) on oncologic outcomes as a part of multimodal treatment in the management of desmoplastic small round cell tumor (DSRCT) and to determine its impact according to the quality of surgical resection. Methods and Materials: All patients treated for primary abdominal DSRCT in 8 French centers from 1991 to 2014 were included. Patients were retrospectively staged into 3 groups: group A treated with adjuvant RT after cytoreductive surgery, group B without RT after cytoreductive surgery, and group C by exclusive chemotherapy. Peritoneal progression-free survival (PPFS), progression-free survival (PFS), and overall survival (OS) were evaluated. We also performed a direct comparison between groups A and B to evaluate RT after cytoreductive surgery. Radiation therapy was also evaluated according to completeness of surgery: complete cytoreductive surgery (CCS) or incomplete cytoreductive surgery (ICS). Results: Thirty-seven (35.9%), thirty-six (34.9%), and thirty (28.0%) patients were included in groups A, B, and C, respectively. Three-year OS was 61.2% (range, 41.0%-76.0%), 37.6% (22.0%-53.1%), and 17.3% (6.3%-32.8%) for groups A, B, and C, respectively. Overall survival, PPFS, and PFS differed significantly among the 3 groups (P<.001, P<.001, and P<.001, respectively). Overall survival and PPFS were higher in group A (RT group) compared with group B (no RT group) (P=.045 and P=.006, respectively). Three-year PPFS was 23.8% (10.3%-40.4%) for group A and 12.51% (4.0%-26.2%) for group B. After CCS, RT improved PPFS (P=.024), but differences in OS and PFS were not significant (P=.40 and P=.30, respectively). After ICS, RT improved OS (P=.044). A trend of PPFS and PFS increase was observed, but the difference was not statistically significant (P=.073 and P=.076). Conclusions: Adjuvant RT as part of multimodal treatment seems to confer oncologic benefits for patients treated for abdominal DSRCT

    Full Text Available Background. Malnutrition has serious implications for recovery after surgery. Early detection of malnutrition with nutritional support minimizes postoperative complications. Nutritional assessment tools need to be simple and suitable for use in everyday practice. In our study we wanted to determine, how many patients might benefit from nutritional support.Methods. From April to August 1999 fifty consecutively admitted patients predicted to major abdominal surgery have been examined. We used Mini nutritional assessment (MNA, Buzby’s nutrition risk index (NRI, blood albumin level and weight loss in the last 3 months period prior to the examination, to assess nutritional status.Results. We examined 50 patients (27 males and 23 females, age 76.5 ± 16.5 and confirmed malnutrition in 40% of patients with MNA and serum albumin level. The increased risk for nutrition-associated complications was confirmed by NRI and weight loss in 44%.Conclusions. A confident diagnosis of malnutrition and increased risk for nutrition-associated complications can be established by using a combination of simple methods like MNA, NRI, weight loss and serum albumin level. Almost half of the patients admitted for major abdominal surgery in General hospital Celje suffer from malnutrition and they may benefit with early nutritional intervention.

    Rupture of abdominal aortic aneurysm is still a difficult challenge for the vascular surgeon due to the high perioperative mortality. The aim of our study is to describe the characteristics of the population as well as to compare morbidity and mortality in patients undergoing open surgery or endovascular repair in our center. Database with 82 rAAA between January 2002-December 2014, studying two cohorts, open surgery and endovascular repair. Epidemiologic, clinical, surgical techniques, perioperative mortality and complications are analyzed. 82 rAAA cases were operated (men: 80, women: 2). Mean age 72±9.6 years. 76.8% (63 cases) was performed by open surgery. smokers 59, 7%, alcoholism 19.5%, DM 10.9%, AHT: 53.6%, dyslipidemia 30.5%. The most frequent clinical presentation was abdominal pain with lumbar irradiation: 50 cases (20.7% associating syncope). Overall hospital mortality was 58.5%. Hemodynamic shock prior to intervention was associated with increased mortality (p .05). The presence of iliac aneurysms was associated with increased mortality (p .05). Hospital stay was lower in the endovascular group (p=.3859). Hemodynamic shock and the presence of concomitant iliac aneurysms have a statistically significant association with perioperative mortality in both groups. We found clinically significant differences in mortality, complications and hospital stay when comparing both groups with better results for EVAR, without statistically significant differences.

    The purpose of this study was to investigate endotracheal tube cuff pressure alteration in patients during laparoscopic cholecystectomy surgery. Forty patients with ASA I-II physical status, who were scheduled for elective laparoscopic (group I) or open abdominal surgery (group II) were enrolled in the study. Tracheal intubation was always performed by an experienced anesthesiologist. The endotracheal tube cuff was inflated with air through a 10-ml syringe. The cuff was connected to a manometer. The endotracheal cuff pressure was registered every 5 min after tracheal intubation. At the time of discharge from the Post-Anesthesia Care Unit (PACU) and 12 h after tracheal extubation, patients were asked about their laryngotracheal condition by an independent observer who was uninformed of the patient allocation groups. We investigated laryngotracheal complaints such as sore throat, dysphasia, and hoarseness. The endotracheal cuff pressures in group I were significantly higher than those in the group II at all time points studied (P pressures exceeded the critical pressure of 30 cmH(2)O after 5 min in the group I (intra-abdominal pneumoperitoneum was started). The incidence of sore throat was higher in group I than in group II in the PACU and at 12 h. This study indicates that the CO(2) pneumoperitoneum and Trendelenburg position used during laparoscopy increase endotracheal cuff pressure and lead to discomfort in the postoperative patient. Measurement of endotracheal cuff pressure is a simple and inexpensive procedure and should be applied in patients under going laparoscopic surgery.

    Full Text Available Abstract Background Intravenous (IV fluid administration is an essential part of postoperative care. Some studies suggest that a restricted post-operative fluid regime reduces complications and postoperative hospital stay after surgery. We investigated the effects of postoperative fluid restriction in surgical patients undergoing major abdominal surgery. Methods In a blinded randomized trial, 62 patients (ASA I-III undergoing elective major abdominal surgical procedures in a university hospital were allocated either to a restricted (1.5 L/24 h or a standard postoperative IV fluid regime (2.5 L/24 h. Primary endpoint was length of postoperative hospital stay (PHS. Secondary endpoints included postoperative complications and time to restore gastric functions. Results After a 1-year inclusion period, an unplanned interim analysis was made because of many protocol violations due to patient deterioration. In the group with the restricted regime we found a significantly increased PHS (12.3 vs. 8.3 days; p = 0.049 and significantly more major complications: 12 in 30 (40% vs. 5 in 32 (16% patients (Absolute Risk Increase: 0.24 [95%CI: 0.03 to 0.46], i.e. a number needed to harm of 4 [95%CI: 2–33]. Therefore, the trial was stopped prematurely. Intention to treat analysis showed no differences in time to restore gastric functions between the groups. Conclusion Restricted postoperative IV fluid management, as performed in this trial, in patients undergoing major abdominal surgery appears harmful as it is accompanied by an increased risk of major postoperative complications and a prolonged postoperative hospital stay.

    The aim of this study was to evaluate the analgesic efficacy, safety, opioid sparing effects and improvement of respiratory function when using 0.2% ropivacaine continuous wound infiltration after major intra-abdominal surgery. Forty patients undergoing major intra-abdominal surgery requiring a midline incision of > or = 20 cm were enrolled into this IRB-approved, randomized, prospective controlled study. Group 1: 20 patients, parenteral analgesia (control group). Group II: 20 patients, with local anesthetic wound infiltration (pain pump group). At the end of the procedure, in the pain pump group of patients, a multi hole, 20-gauge catheter was inserted percutaneously, above the fascia. An initial dose of 10 ml of 0.2% ropivacaine was injected in the wound through the catheter. A device provided continuous delivery of 0.2% ropivacaine; the infusion was initiated at 6 ml/h for the following two days. The total "rescue" morphine and oxycodone/acetaminophen tablets administered were significantly lower in the pain pump group. At all time intervals, resting pain scores were significantly lower in the pain pump group when compared with the control group. However, at the 4-48 and 12-48 hours pain scores generated after leg raise and coughing, respectively, were significantly lower in group II. The patient vital capacities were insignificantly higher in group II. We conclude that after major abdominal surgery, infiltration and continuous wound instillation with 0.2% ropivacaine decreases postoperative pain, opioid requirements and oral analgesia. Early patient rehabilitation, hastening convalescence, and preventing respiratory complications are expected outcomes of this approach.

    Background: Post-operative pain is often inadequately treated. Optimal utilization of the available resources is essential for improving pain management. Aims: The aim of our study was to determine pain management strategies employed after major abdominal surgeries at our institute and their efficacy and safety. Settings and Design: Prospective observational study conducted at a tertiary care hospital. Materials and Methods: Patients undergoing elective major abdominal surgeries were included. Post-operative analgesic strategy, co-analgesics used, pain and sedation scores, motor block, nausea and vomiting were recorded and patient satisfaction was determined. Results: Data was collected on 100 patients. Epidural analgesia was used in 61, patient controlled intravenous analgesia (PCIA) in 25 and opioid infusion in 14 patients. Multimodal analgesia was employed in 98 patients. The level of epidural was between L1-L3 in 31, T10-L1 in 20 and T8-T10 in 10 patients. Pethidine was used in 80% of patients receiving PCIA. Patients with epidurals at T8-T10 had lower pain scores. Fifteen patients had motor block, 73% of which were with epidural at L1-L3. Fourteen patients complained of nausea. Ninety nine out of 100 patients were satisfied with their analgesia. Conclusion: Epidural, PCIA and opioid infusions are used for pain relief after major abdominal surgeries at our hospital. Although there is limited drug availability, regular assessments and appropriate dose adjustments by acute pain management service (APMS) and use of multimodal analgesia led to a high level of patient satisfaction. We recommend that feedback to the primary anesthesiologists by APMS is of utmost importance to enable improvement in practice. PMID:24249983

    Background Current methods to predict patients' peri-operative morbidity utilize complex algorithms with multiple clinical variables focusing primarily on organ-specific compromise. The aim of the present study is to determine the value of a timed stair climb (SC) in predicting peri-operative complications for patients undergoing abdominal surgery. Study Design From March 2014 to July 2015, 362 patients attempted SC while being timed prior to undergoing elective abdominal surgery. Vital signs were measured before and after SC. Ninety day post-operative complications were assessed by the Accordion Severity Grading System. The prognostic value of SC was compared to the ACS NSQIP risk calculator. Results A total of 264 (97.4%) patients were able to complete SC. SC time directly correlated to changes in both mean arterial pressure and heart rate as an indicator of stress. An Accordion grade 2 or higher complication occurred in 84 (25%) patients. There were 8 mortalities (2.4%). Patients with slower SC times had an increased complication rate (P<0.0001). In multivariable analysis SC time was the single strongest predictor of complications (OR=1.029, P<0.0001), and no other clinical co-morbidity reached statistical significance. Receiver operative characteristic curves predicting post-operative morbidity by SC time was superior to that of the ACS risk calculator (AUC 0.81 vs. 0.62, P<0.0001). Additionally slower patients had a greater deviation from predicted length of hospital stay (P=0.034) Conclusions SC provides measurable stress, accurately predicts post-operative complications, and is easy to administer in patients undergoing abdominal surgery. Larger patient populations with a diverse group of operations will be needed to further validate the use of SC in risk prediction models. PMID:26920993

    This article presents general principles and recent advancements in the clinical application of augmented reality-based navigation surgery (AR based NS) for abdominal procedures and includes a description of our clinical trial and subsequent outcomes. Moreover, current problems and future aspects are discussed. The development of AR-based NS in the abdomen is delayed compared with another field because of the problem of intraoperative organ deformations or the existence of established modalities. Although there are a few reports on the clinical use of AR-based NS for digestive surgery, sophisticated technologies in urology have often been reported. However, the rapid widespread use of video- or robot assisted surgeries requires this technology. We have worked to develop a system of AR-based NS for hepatobiliary and pancreatic surgery. Then we developed a short rigid scope that enables surgeons to obtain 3D view. We recently focused on pancreatic surgery, because intraoperative organ shifting is minimal. The position of each organ in overlaid image almost corresponded with that of the actual organ with about 5 mm of mean registration errors. Intraoperative information generated from this system provided us with useful navigation. However, AR-based NS has several problems to overcome such as organ deformity, evaluation of utility, portability or cost.

    The need for nonobstetric abdominal surgical interventions in pregnant females arises periodically in practice and can be a source for concern for both the patient and the surgeon because of the risk of adverse outcome. To determine the indications for, and assess maternal and fetal outcome following nonobstetric abdominal surgeries in Jos University Teaching Hospital. This was a retrospective cross-sectional study analyzing clinical records of pregnant women, who had nonobstetric abdominal surgeries in Jos University Teaching Hospital between January 2007 and December 2011. Fifty patients had nonobstetric abdominal surgery during the study period (January 2007 to December 2011). The ages of the women ranged 15-49 years with a mean of 29 ± 8.13 years. Intraoperative findings in the patients were consistent with acute appendicitis in 43 (86%) patients, two patients (4%) had ruptured spleen while one patient each (2.0%) had a transverse colon injury, postoperative adhesion bands, ruptured uterus and urinary bladder, and mesenteric injury. One (2.0%) mother died after surgery. 38 (76%) had spontaneous deliveries, and there were 11 miscarriages (22%) and 1 perinatal death. The perinatal mortality rate was 0.093/1000 deliveries. The mean hospital stay was 5.52 days. Nonobstetric abdominal surgeries in pregnant women are an infrequent occurrence at Jos University Teaching Hospital but when they do occur, they are indicated by acute appendicitis in pregnancy.

    Early mobilization after major abdominal surgery decreases postoperative complications and length of stay, and has become a key component of enhanced recovery pathways. However, objective measures of patient movement after surgery are limited. Real-time location systems (RTLS), typically used for asset tracking, provide a novel approach to monitoring in-hospital patient activity. The current study investigates the feasibility of using RTLS to objectively track postoperative patient mobilization. The real-time location system employs a meshed network of infrared and RFID sensors and detectors that sample device locations every 3 s resulting in over 1 million data points per day. RTLS tracking was evaluated systematically in three phases: (1) sensitivity and specificity of the tracking device using simulated patient scenarios, (2) retrospective passive movement analysis of patient-linked equipment, and (3) prospective observational analysis of a patient-attached tracking device. RTLS tracking detected a simulated movement out of a room with sensitivity of 91% and specificity 100%. Specificity decreased to 75% if time out of room was less than 3 min. All RTLS-tagged patient-linked equipment was identified for 18 patients, but measurable patient movement associated with equipment was detected for only 2 patients (11%) with 1-8 out-of-room walks per day. Ten patients were prospectively monitored using RTLS badges following major abdominal surgery. Patient movement was recorded using patient diaries, direct observation, and an accelerometer. Sensitivity and specificity of RTLS patient tracking were both 100% in detecting out-of-room ambulation and correlated well with direct observation and patient-reported ambulation. Real-time location systems are a novel technology capable of objectively and accurately monitoring patient movement and provide an innovative approach to promoting early mobilization after surgery.

    Single incision laproscopic surgery (SILS) involves performing abdominal operations with laparoscopic instruments placed through a single, small umbilical incision. The primary goal is to avoid visible scarring. This is the first report of SILS cholecystectomy in children and the first report in the literature of SILS splenectomy. A retrospective chart review was performed in 20 consecutive inpatient SILS procedures (13 males, 7 females; ages 2-17 years) from May to December 2008. Outcome measures included need for conversion, operative time, time to oral analgesia, length of hospitalization, cosmetic outcome, and complications. There were 4 total splenectomies, 3 cholecystectomies, 2 combined splenectomy/cholecystectomies, and 11 appendectomies performed. All procedures were completed successfully without need for conversion to standard laparoscopy or open surgery. Mean operative time was 90 minutes for splenectomy, 68 minutes for cholecystectomy, 165 minutes for combined splenectomy/cholecystectomy, and 33 minutes for appendectomy. Mean hospital stay was 1 day for appendectomy, 1 day for cholecystectomy, and 2.5 days for splenectomy. One splenectomy patient received 1 U packed red blood cell transfusion. All appendectomy patients were converted to oral analgesia within 24 hours and splenectomy patients within 48 hours. All families were very pleased with the cosmetic outcome. Single incision laparoscopic surgery is feasible for a variety of pediatric general surgical conditions, allowing for scarless abdominal operations. This early experience suggests that outcomes are comparable to standard laparoscopic surgery but with improved cosmesis, however, a larger series is necessary to confirm these findings and to determine if there are any benefits in pain or recovery. Surgeons performing SILS should have a firm foundation of advanced minimal access surgical skills and a cautious, gradated approach to attempting the various procedures. Technological refinements will

    This paper investigates different types of crimped, braided sleeve used for a soft arm for robotic abdominal surgery, with the sleeve required to contain balloon expansion in the pneumatically actuating arm while it follows the required bending, elongation and diameter reduction of the arm. Three types of crimped, braided sleeves from PET (BraidPET) or nylon (BraidGreyNylon and BraidNylon, with different monofilament diameters) were fabricated and tested including geometrical and microstructural characterisation of the crimp and braid, mechanical tests and medical scratching tests for organ damage of domestic pigs. BraidPET caused some organ damage, sliding under normal force of 2-5 N; this was attributed to the high roughness of the braid pattern, the higher friction coefficient of polyethylene terephthalate (PET) compared to nylon, and the high frequency of the crimp peaks for this sleeve. No organ damage was observed for the BraidNylon, attributed to both the lower roughness of the braid pattern and the low friction coefficient of nylon. BraidNylon also required the lowest tensile force during its elongation to similar maximum strain as that of BraidPET, translating to low power requirements. BraidNylon is recommended for the crimped sleeve of the arm designed for robotic abdominal surgery.

    The impact of postoperative complications after Major Abdominal Surgery (MAS) is substantial, especially when socio-economical aspects are taken into account. This systematic review focuses on the effects of preoperative exercise therapy (PEXT) on physical fitness prior to MAS, length of hospital admission and postoperative complications in patients eligible for MAS, and on what is known about the most effective kind of exercise regime. A systematic search identified randomised controlled trials on exercise therapy and pulmonary physiotherapy prior to MAS. The methodological quality of the included studies was rated using the 'Delphi List For Quality Assessment of Randomised Clinical Trials'. The level of agreement between the two reviewers was estimated with Cohen's kappa. A total of 6 studies were included, whose methodological quality ranged from moderate to good. Cohen's kappa was 0.90. Three studies reported on improving physical fitness prior to MAS with the aid of PEXT. Two studies reported on the effect of training on postoperative complications, showing contradictory results. Three studies focused on the effect of preoperative chest physiotherapy on postoperative lung function parameters after MAS. While the effects seem positive, the optimal training regime is still unclear. Preoperative exercise therapy might be effective in improving the physical fitness of patients prior to major abdominal surgery, and preoperative chest physiotherapy seems effective in reducing pulmonary complications. However consensus on training method is lacking. Future research should focus on the method and effect of PEXT before high-risk surgical procedures. Copyright © 2013 Surgical Associates Ltd.

    There has been recent interest in using high-concentration oxygen to prevent surgical site infections (SSIs). Previous meta-analyses in this area have produced conflicting results. With the publication of 2 new randomized controlled trials (RCTs) that were not included in previous meta-analyses, an updated review is warranted. Our objective was to perform a meta-analysis on RCTs comparing high- and low- concentration oxygen in adults undergoing open abdominal surgery. We completed independent literature reviews using electronic databases, bibliographies and other sources of grey literature to identify relevant studies. We assessed the overall quality of evidence using grade guidelines. Statistical analysis was performed on pooled data from included studies. A priori subgroup analyses were planned to explain statistical and clinical heterogeneity. Overall, 6 studies involving a total of 2585 patients met the inclusion criteria. There was no evidence of a reduction in SSIs with high-concentration oxygen (risk ratio 0.77, 95% confidence interval 0.50-1.19, p = 0.24). We observed substantial heterogeneity among studies. There is moderate evidence that high-concentration oxygen does not reduce SSIs in adults undergoing open abdominal surgery.

    Even though wound dehiscence is a surgical complication, under certain medical conditions, repetition of the laparotomy (LT) (relaparotomy) can become inevitable. In addition to the risks associated with this surgical operation, relaparotomy can interfere with the tissue healing and contribute to the development of chronic wounds. In an experimental relaparotomy wounding model, this study investigated the impact of repeated surgery on wound healing and on the immune cells of myeloid origin. The first repeat of the LT triggered fibrosis and marginally interfered with the wound healing; however, the second operation completely abrogated the healing process. Splenomegaly was observed as an indicator of the chronic inflammation and the systemic effect of repeated laparotomies. In the blood stream, the spleen, and the liver, these repeated surgeries exhibited a major impact on the CD11b + Ly6C + Ly6G - monocytes. On the other hand, especially, whespecially the second relaparotomy resulted in a massive purging of neutrophil granulocytes into the circulation. These CD11b + Ly6C + Ly6G + neutrophils that were disseminated on repeated abdominal laparotomies had a proinflammatory character that positively influenced T cell proliferation and displayed a high capacity for production of reactive oxygen species. The repetition of abdominal LT not only interferes with the wound healing but also contributes to the development of imperfectly healing wounds which have systemic impact on immune compartments.

    2016-01-01

    Summary Purpose of Investigation Pain control and early ambulation are two important postoperative goals. Strategies that decrease morphine use while increasing ambulation have the potential to decrease postoperative complications. In this study the authors sought to determine the effect of an abdominopelvic binder on postoperative morphine use, pain, and ambulation in the first day after surgery. Materials and Methods The authors randomly assigned 75 patients undergoing abdominal gynecologic surgery to either binder or not after surgery. Demographic data and surgical characteristics were collected. Outcome variables included morphine use, pain score, time to ambulation, and number of ambulations. Results A group at high risk for decreased mobility was identified and the binder increased the number of ambulatory events by 300%, 260%, and 240% in patients with vertical incisions, age over 50 years, and complex surgeries, respectively. Morphine use and pain scores were not significantly different. Conclusion The binder increased ambulations in the subset of patients at the highest risk for postoperative complications: elderly, cancer patients, and vertical incisions. Routine use of the binder may benefit particularly high-risk gynecologic surgical patients. PMID:25864252

    Acute kidney injury (AKI) is a frequent complication in high-risk patients undergoing major surgery and is associated with longer hospital stay, increased risk for nosocomial infection and significantly higher costs. A prospective observational study exploring the incidence of AKI (AKIN classification at any stage) in high-risk patients within 48 hours after major abdominal surgery was conducted. Patients' preoperative characteristics, intraoperative management, and outcome were evaluated for associations with AKI using a logistic regression model. Data from 258 patients were analyzed. Thirty-one patients (12%) developed AKI, reaching the AKIN stage 1. No patient reached an AKIN stage higher than 1. AKI patients were older (75.2 vs 70.2 years; P = 0.0113) and had a higher body mass index (26.5 vs 25.1 kg/m(2)). In addition, AKI patients had a significantly longer ICU length of stay (3.4 vs 2.4 days; P= .0017). Creatinine levels of AKI patients increased significantly compared to the preoperative levels at 24 (P= .0486), 48 (P= .0011) and 72 hours (P= .0055), while after 72 hours it showed a downwards trend. At ICU discharge, 28 out of 31 patients (90.3%) recovered preoperative levels. Multivariate analysis identified age (OR 1.088; P= .002) and BMI (OR 1.124; P= .022) as risk factors for AKI development. Moreover, AKI development was an independent risk factor for ICU stays longer than 48 hours (OR 2.561; P= .019). Mild AKI is a not rare complication in high-risk patients undergoing major abdominal surgery. Although in almost the totality of cases, the indicators of renal function recovered to preoperative levels, post-operative AKI represents a primary risk factor for a prolonged ICU stay.

    Full Text Available Abdominal surgery inhibits food intake and induces c-Fos expression in the hypothalamic and medullary nuclei in rats. Rikkunshito (RKT, a Kampo medicine improves anorexia. We assessed the alterations in meal microstructure and c-Fos expression in brain nuclei induced by abdominal surgery and the modulation by RKT in mice. RKT or vehicle was gavaged daily for 1 week. On day 8 mice had no access to food for 6-7 h and were treated twice with RKT or vehicle. Abdominal surgery (laparotomy-cecum palpation was performed 1-2 h before the dark phase. The food intake and meal structures were monitored using an automated monitoring system for mice. Brain sections were processed for c-Fos immunoreactivity (ir 2-h after abdominal surgery. Abdominal surgery significantly reduced bouts, meal frequency, size and duration, and time spent on meals, and increased inter-meal interval and satiety ratio resulting in 92-86% suppression of food intake at 2-24 h post-surgery compared with control group (no surgery. RKT significantly increased bouts, meal duration and the cumulative 12-h food intake by 11%. Abdominal surgery increased c-Fos in the prelimbic, cingulate and insular cortexes, and autonomic nuclei, such as the bed nucleus of the stria terminalis, central amygdala, hypothalamic supraoptic (SON, paraventricular and arcuate nuclei, Edinger-Westphal nucleus (E-W, lateral periaqueduct gray (PAG, lateral parabrachial nucleus, locus coeruleus, ventrolateral medulla and nucleus tractus solitarius (NTS. RKT induced a small increase in c-Fos-ir neurons in the SON and E-W of control mice, and in mice with surgery there was an increase in the lateral PAG and a decrease in the NTS. These findings indicate that abdominal surgery inhibits food intake by increasing both satiation (meal duration and satiety (meal interval and activates brain circuits involved in pain, feeding behavior and stress that may underlie the alterations of meal pattern and food intake inhibition

    2016-09-01

    Full Text Available This article provides a review of the causes of respiratory tract infection after abdominal surgery. These causes include general anesthesia, intubation factors, factors inherent to the patient, surgical factors, the injudicious use of antimicrobial agents, and the environmental factors of the ward. The perioperative management of the respiratory tract should be strengthened. Health education, respiratory function training, oral nursing intervention, atomization inhalation, and personalized expectoration methods should receive more attention to decrease the complications and promote the early rehabilitation of patients after abdominal surgery.

    Introduction Surgical procedures in abdominal area lead to changes in pulmonary function, respiratory mechanics and impaired physical capacity leading to postoperative pulmonary complications, which can affect up to 80% of upper abdominal surgery. Aim To evaluate the effects of flow and volume incentive spirometry on pulmonary function and exercise tolerance in patients undergoing open abdominal surgery. Materials and Methods A randomized clinical trial was conducted in a hospital of Mangalore city in Southern India. Thirty-seven males and thirteen females who were undergoing abdominal surgeries were included and allocated into flow and volume incentive spirometry groups by block randomization. All subjects underwent evaluations of pulmonary function with measurement of Forced Vital Capacity (FVC), Forced Expiratory Volume in the first second (FEV1), Peak Expiratory Flow (PEF). Preoperative and postoperative measurements were taken up to day 5 for both groups. Exercise tolerance measured by Six- Minute Walk Test during preoperative period and measured again at the time of discharge for both groups. Pulmonary function was analysed by post-hoc analysis and carried out using Bonferroni’s ‘t’-test. Exercise tolerance was analysed by Paired ‘T’-test. Results Pulmonary function (FVC, FEV1, and PEFR) was found to be significantly decreased in 1st, 2nd and 3rd postoperative day when compared with preoperative day. On 4th and 5th postoperative day the pulmonary function (FVC, FEV1, and PEFR) was found to be better preserved in both flow and volume incentive spirometry groups. The Six-Minute Walk Test showed a statistically significant improvement in pulmonary function on the day of discharge than in the preoperative period. In terms of distance covered, the volume- incentive spirometry group showed a greater statistically significant improvement from the preoperative period to the time of discharge than was exhibited by the flow incentive spirometry group

    Dislodgement of ports from the abdominal wall is a common problem during laparoscopic surgery. The aim of this study was to evaluate port stability using either cutting or blunt-tipped trocars. Patients undergoing laparoscopic surgery were randomized to have the secondary ports inserted using either cutting or blunt-tipped trocars. The fixity of ports to the abdominal wall was evaluated at the start and completion of surgery by measuring the total traction force required to displace the ports. Similarly, the friction forces required to displace instruments within the ports were measured. Thirty patients were randomized into two groups (15 patients in each group), and a total of 114 ports (cutting, n = 51; blunt, n = 63) were evaluated. The groups were comparable in age, gender, body mass index, and operating time. The total traction forces needed to displace the 5-mm and 10-mm ports were significantly lower when cutting trocars were used at both the beginning (2.6 vs. 11.8 N, p fixity to the abdominal wall during laparoscopic surgery declines with time. The insertion of ports using a blunt-tipped trocar is associated with significantly greater stability and fixity of the port to the abdominal wall. The use of blunt-tipped trocars is recommended for routine practice in laparoscopic surgery.

Retrospective analysis of 86 patients with T 1-2 N 0-1 OSCC who received surgery between January 2000 and December 2006. Fourteen patients (16.3%) received postoperative radiotherapy (PORT). Patient characteristics, tumor characteristics, treatment modality, failure patterns, and survival rates were analyzed. The median follow-up was 45 months. The five-year overall survival (OS) and disease-free survival (DFS) rates were 80.8% and 80.2%, respectively. Higher tumor grade and invasion depth ≥ 0.5 cm were the significant prognostic factors affecting five-year OS and DFS (OS rate; 65% vs. 91%, p = 0.001 for grade; 66% vs. 92%, p = 0.01 for invasion depth: DFS rate; 69% vs. 88%, p = 0.005 for grade; 66% vs. 92%, p = 0.013 for invasion depth). In the risk group, there was no local failure in patients with postoperative radiotherapy. In T 1-2 N 0-1 OSCC, factors that affected prognosis after primary surgery were higher tumor grade and deep invasion depth over 0.5 cm. Postoperative radiotherapy should be considered in early oral tongue cancer patients with these high-risk pathologic features

    2006-03-01

    Long-term follow-up of patients born with classical bladder exstrophy-epispadias complex (EEC) reveals that many of them suffer from poor self-image, and the aesthetic aspects of the genitalia and lower abdomen acquire greater significance with age. In this article, we review the aesthetic outcomes in performing puboplasty, umbilicoplasty, and genitoplasty in patients born with EEC. Retrospective review of the cosmetic and functional outcomes in 116 patients born with EEC treated by puboplasty, umbilicoplasty, or genitoplasty was performed. Satisfaction with the cosmetic and functional outcomes of these three reconstructive surgeries was high following initial reconstructive efforts (> 90%). Attention to cosmesis during abdominal wall and genital reconstruction for EEC helps to improve a patient's perception of body image and self-esteem. Our experience with these procedures over the past 25 years demonstrated that the efforts directed toward aesthetics have been well worthwhile.

    The techniques derived from abdominal transplant surgery have become a major actor in recent surgical evolution by providing a more optimal solution for urologic malignancies hosted in the upper abdomen. To describe in detail the objectives, rationale, relevant milestones, and surgical maneuvers of the so-called transplant techniques as applied to complex urologic oncology cases. The transplant-based surgical approach aims to decrease perioperative complications by improving tumor accessibility and field visibility through an enhanced exposure (via the use of a transverse incision, a specific retractor, and specific surgical maneuvers). A sequence of milestones inspired these advances, which finally brought the technique into maturation. The transplant-based approach has demonstrated its safety and usefulness even in the low-volume practice of more complicated urologic oncology, offering protection against the occurrence of perioperative adverse events and placing us at the gates of a new stage of surgical innovation.

Postoperatively she developed abdominal and lower back pain, which was treated with an injection of analgesics in an epidural catheter. The following morning it was discovered that the patient had cold legs with pallor and no palpable femoral pulse. Rigor mortis and livor mortis were diagnosed in both legs, even though the patient was still alive and awake. Doppler ultrasound examination revealed the absence of blood flow in the lower part of the abdominal aorta and distally. A cross disciplinary conference including specialists in urology, orthopaedics, vascular surgery, anaesthesiology, internal medicine, and intensive care concluded that no lifesaving treatment was possible, and the patient died the following day. A forensic autopsy revealed severe atherosclerosis with thrombosis and dissection of the abdominal aorta. This case clearly demonstrates that a vascular emergency should be considered when patients complain about pain in the lower back, abdomen or limbs. Clinicians should be especially aware of symptoms of tissue death that can be masked by epidural analgesia.

    Incisional hernias are one of the most common long-term complications associated with open abdominal surgery. The aim of this review and meta-analysis was to systematically assess laparoscopic versus open abdominal surgery as a general surgical strategy in all available indications in terms of incisional hernia occurrence. A systematic literature search was performed to identify randomized controlled trials comparing incisional hernia rates after laparoscopic versus open abdominal surgery in all indications. Random effects meta-analyses were calculated and presented as risk differences (RD) with their corresponding 95 % confidence intervals (CI). 24 trials (3490 patients) were included. Incisional hernias were significantly reduced in the laparoscopic group (RD -0.06, 95 % CI [-0.09, -0.03], p = 0.0002, I (2) = 75). The advantage of the laparoscopic procedure persisted in the subgroup of total-laparoscopic interventions (RD -0.14, 95 % CI [-0.22, -0.06], p = 0.001, I (2) = 87 %), whereas laparoscopically assisted procedures did not show a significant reduction of incisional hernias compared to open surgery (RD -0.01, 95 % CI [-0.03, 0.01], p = 0.31, I (2) = 35 %). Wound infections were significantly reduced in the laparoscopic group (RD -0.06, 95 % CI [-0.09, -0.03], p abdominal surgery showed a significantly longer hospital stay compared to laparoscopy (RD -1.92, 95 % CI [-2.67, -1.17], p hernias are less frequent using the total-laparoscopic approach instead of open abdominal surgery. Whenever possible, the less traumatic access should be chosen.

There are several different clinical variations in the approaches used for achieving analgesia via TAP infiltration, and methods for identification of the TAP have evolved considerably since the landmark-guided technique was first described in 2001. There are many factors that impact the analgesic outcomes following TAP infiltration, and the various nuances of this technique have led to debate regarding procedural classification of TAP infiltration. Based on our current understanding of fascial and neuronal anatomy of the anterior abdominal wall, as well as available evidence from studies assessing local anesthetic spread and cutaneous sensory block following TAP infiltration, it is clear that TAP infiltration techniques are appropriately classified as field blocks. While the objective of peripheral nerve block and TAP infiltration are similar in that both approaches block sensory response in order to achieve analgesia, the technical components of the two procedures are different. Unlike peripheral nerve block, which involves identification or stimulation of a specific nerve or nerve plexus, followed by

    To examine the efficacy of respiratory physiotherapy for prevention of pulmonary complications after abdominal surgery. We searched in databases and bibliographies for articles in all languages through November 2005. Randomized trials were included if they investigated prophylactic respiratory physiotherapy and pulmonary outcomes, and if the follow-up was at least 2 days. Efficacy data were expressed as risk differences (RDs) and number needed to treat (NNT), with 95% confidence intervals (CIs). Thirty-five trials tested respiratory physiotherapy treatments. Of 13 trials with a "no intervention" control group, 9 studies (n = 883) did not report on significant differences, and 4 studies (n = 528) did: in 1 study, the incidence of pneumonia was decreased from 37.3 to 13.7% with deep breathing, directed cough, and postural drainage (RD, 23.6%; 95% CI, 7 to 40%; NNT, 4.3; 95% CI, 2.5 to 14); in 1 study, the incidence of atelectasis was decreased from 39 to 15% with deep breathing and directed cough (RD, 24%; 95% CI, 5 to 43%; NNT, 4.2; 95% CI, 2.4 to 18); in 1 study, the incidence of atelectasis was decreased from 77 to 59% with deep breathing, directed cough, and postural drainage (RD, 18%; 95% CI, 5 to 31%; NNT, 5.6; 95% CI, 3.3 to 19); in 1 study, the incidence of unspecified pulmonary complications was decreased from 47.7% to 21.4 to 22.2% with intermittent positive pressure breathing, or incentive spirometry, or deep breathing with directed cough (RD, 25.5 to 26.3%; NNT, 3.8 to 3.9). Twenty-two trials (n = 2,734) compared physiotherapy treatments without no intervention control subjects; no conclusions could be drawn. There are only a few trials that support the usefulness of prophylactic respiratory physiotherapy. The routine use of respiratory physiotherapy after abdominal surgery does not seem to be justified.

    The Dutch Surgical Aneurysm Audit (DSAA) is mandatory for all patients with primary abdominal aortic aneurysms (AAAs) in the Netherlands. The aims are to present the observed outcomes of AAA surgery against the predicted outcomes by means of V-POSSUM (Vascular-Physiological and Operative Severity Score for the enUmeration of Mortality and Morbidity). Adjusted mortality was calculated by the original and re-estimated V(physiology)-POSSUM for hospital comparisons. All patients operated on from January 2013 to December 2014 were included for analysis. Calibration and discrimination of V-POSSUM and V(p)-POSSUM was analysed. Mortality was benchmarked by means of the original V(p)-POSSUM formula and risk-adjusted by the re-estimated V(p)-POSSUM on the DSAA. In total, 5898 patients were included for analysis: 4579 with elective AAA (EAAA) and 1319 with acute abdominal aortic aneurysm (AAAA), acute symptomatic (SAAA; n = 371) or ruptured (RAAA; n = 948). The percentage of endovascular aneurysm repair (EVAR) varied between hospitals but showed no relation to hospital volume (EAAA: p = .12; AAAA: p = .07). EAAA, SAAA, and RAAA mortality was, respectively, 1.9%, 7.5%, and 28.7%. Elective mortality was 0.9% after EVAR and 5.0% after open surgical repair versus 15.6% and 27.4%, respectively, after AAAA.

    AIM: To investigate distal small bowel motility and lipid absorption in patients following elective abdominal aortic aneurysm (AAA) repair surgery. METHODS: Nine patients (aged 35-78 years; body mass index (BMI) range: 23-36 kg/m2) post-surgery for AAA repair, and seven healthy control subjects (20-50 years; BMI range: 21-29 kg/m2) were studied. Continuous distal small bowel manometry was performed for up to 72 h, during periods of fasting and enteral feeding (Nutrison®). Recordings were analyzed for the frequency, origin, length of migration, and direction of small intestinal burst activity. Lipid absorption was assessed on the first day and the third day post surgery in a subset of patients using the 13C-triolein-breath test, and compared with healthy controls. Subjects received a 20-min intraduodenal infusion of 50 mL liquid feed mixed with 200 μL 13C-triolein. End-expiratory breath samples were collected for 6 h and analyzed for 13CO2 concentration. RESULTS: The frequency of burst activity in the proximal and distal small intestine was higher in patients than in healthy subjects, under both fasting and fed conditions (P < 0.005). In patients there was a higher proportion of abnormally propagated bursts (71% abnormal), which began to normalize by d 3 (25% abnormal) post-surgery. Lipid absorption data was available for seven patients on d 1 and four patients on d 3 post surgery. In patients, absorption on d 1 post-surgery was half that of healthy control subjects (AUC 13CO2 1 323 ± 244 vs 2 646 ±365; P < 0.05, respectively), and was reduced to the one-fifth that of healthy controls by d 3 (AUC 13CO2 470 ± 832 vs 2 646 ± 365; P < 0.05, respectively). CONCLUSION: Both proximal and distal small intestinal motor activity are transiently disrupted in critically ill patients immediately after major surgery, with abnormal motility patterns extending as far as the ileum. These motor disturbances may contribute to impaired absorption

    Full Text Available Background: Cardiopulmonary bypass is known to cause inflammatory events. Inflammation occurs due to many known important biological processes. Numerous mechanisms are known to be responsible for the development of inflammatory processes. Currently, there are many defined mediators as a tumor necrosis factor-α (TNF-α playing an active role in this process. Aims: This research was to investigate the effects of preoperative steroid use on inflammatory mediator TNF-α and on time to extubation postoperatively in ventricular septal defect patients undergoing cardiopulmonary bypass surgery. Study Design: Controlled clinical study. Methods: This study included 30 patients. These patients were assigned into two groups, each containing 15 patients. 5 micrograms/kg methylprednisolone was injected intravenously 2 hours before the surgery to Group I, whereas there was no application to the patients in Group II. TNF-α (pg/mL level was measured in arterial blood samples obtained at four periods including: the preoperative period (Pre TNF; at the 5th minute of cross-clamping (Per TNF; 2 hours after termination of cardiopulmonary bypass (Post TNF; and at the postoperative 24th hours in cardiovascular surgery intensive care unit (Post 24 h TNF. Results: The mean cross-clamp time was 66±40 and 55±27 minutes in Group I and Group II respectively. No significant difference was found between the groups in terms of cross-clamp time (p>0.05. The mean time to extubation was 6.1±2.3 hours in Group I and 10.6±3.4 hours in Group II. Group I extubation time was significantly shorter than Group II. Group I TNF-α levels at Post TNF and Post24h TNF was lower than Group II. These differences are also statistically significant (p<0.05. Conclusion: There is a strong indication that preoperative steroid treatment reduced the TNF-α level together with shortens duration of postoperative intubation and positively contributes to extubation in ventricular septal defect

    Full Text Available Cerebrospinal fluid (CSF leak is the most commonly encountered perioperative complication in transsphenoidal surgery for pituitary lesions. Direct closure with a combination of autologous fat, local bone, and/or synthetic grafts remains the standard of care for leaks encountered at the time of surgery as well as postoperatively. The development of the vascularized nasoseptal flap as a closure technique has increased the surgeon’s capacity to correct even larger openings in the dura of the sella as well as widely exposed anterior skull base defects. Yet these advances in the technical nuances for management of post-transsphenoidal CSF leak are useless without the ability to recognize a CSF leak by physical examination, clinical history, biochemical testing, or radiographic assessment. Here, we report a case of a patient who developed a CSF leak 28 years after transsphenoidal surgery, precipitated by a robotic-assisted hysterectomy during which increased intra-abdominal pressure and steep Trendelenberg positioning were both factors. Given the remote nature of the patient’s transsphenoidal surgery and relative paucity of data regarding such a complication, the condition went unrecognized for several months. We review the available literature regarding risk and pathophysiology of CSF leak following abdominal surgery and propose the need for increased vigilance in identification of such occurrences with the increasing acceptance and popularity of minimally invasive abdominal and pelvic surgeries as standards in the field.

    MARIA VITÓRIA FRANÇA DO AMARAL

    Full Text Available ABSTRACT We describe the preliminary national experience and the early results of the use of robotic surgery to perform the posterior separation of abdominal wall components by the Transversus Abdominis Release (TAR technique for the correction of complex defects of the abdominal wall. We performed the procedures between 04/2/2015 and 06/15/2015 and the follow-up time was up to six months, with a minimum of two months. The mean surgical time was five hours and 40 minutes. Two patients required laparoscopic re-intervention, since one developed hernia by peritoneal migration of the mesh and one had mesh extrusion. The procedure proved to be technically feasible, with a still long surgical time. Considering the potential advantages of robotic surgery and those related to TAR and the results obtained when these two techniques are associated, we conclude that they seem to be a good option for the correction of complex abdominal wall defects.

    To correlate spinopelvic balance with the development of degenerative spondylolisthesis and disk herniation. This was a descriptive retrospective study that evaluated 60 patients in this hospital, 30 patients with degenerative spondylolisthesis at the L4-L5 level and 30 with herniated disk at the L4-L5 level, all of whom underwent Surgical treatment. Patients with lumbar disk herniation at L4-L5 level had a mean tilt of 8.06, mean slope of 36.93, and mean PI of 45. In patients with degenerative spondylolisthesis at the L4-L5 level, a mean tilt of 22.1, mean slope of 38.3, and mean PI of 61.4 were observed. This article reinforces the finding that the high mean tilt and PI are related to the onset of degenerative spondylolisthesis, and also concluded that the same angles, when low, increase the risk for disk herniation.

    Full Text Available Introduction: There is a steady increase in the number of elderly patients with severe cardiovascular diseases who require a surgical procedure to recover some quality of life that allows them a socially meaningful existence, despite the risks. Objectives: To analyze the behavior of elderly patients who underwent cardiac surgery with cardiopulmonary bypass. Method: A descriptive, retrospective, cross-sectional study was conducted with patients over 65 years of age who underwent surgery at the Cardiocentro Ernesto Che Guevara, in Santa Clara, from January 2013 to March 2014. Results: In the study, 73.1% of patients were men; and there was a predominance of subjects between 65 and 70 years of age, accounting for 67.3%. Coronary artery bypass graft was the most prevalent type of surgery and had the longest cardiopulmonary bypass times. Hypertension was present in 98.1% of patients. The most frequent postoperative complications were renal dysfunction and severe low cardiac output, with 44.2% and 34.6% respectively. Conclusions: There was a predominance of men, the age group of 65 to 70 years, hypertension, and patients who underwent coronary artery bypass graft with prolonged cardiopulmonary bypass. Renal dysfunction was the most frequent complication.

    The Estimation of Physiologic Ability and Surgical Stress (E-PASS) scoring system, which quantifies a patient's reserve and surgical stress, is used to predict morbidity and mortality in patients before elective gastrointestinal surgery. We conducted this study to clarify whether the E-PASS scoring system is useful for assessing the risks of emergency abdominal surgery. The subjects of this retrospective study were 51 patients who underwent emergency gastrointestinal surgery at a public general hospital. The main outcomes were the E-PASS scores and the postoperative course, defined by mortality and morbidity. Postoperative complications developed in 15 of the 51 patients (29.4%). The E-PASS score was significantly higher in the patients with postoperative complications than in those without (0.61 ± 0.31 vs 0.20 ± 0.35, respectively; n = 36). The morbidity rates were significantly lower in the patients with a value less than 0.5 than in those with a value more than 0.5 (17.1% and 56.3%, respectively; P high score, versus none among the 9 patients with a low score (P surgery. Minimally invasive therapy would assist in lowering the risk of complications.

    Postoperative nausea and vomiting (PONV) is the most common postoperative complication. The postoperative use of opioids is known to increase the incidence. We compared fosaprepitant, a neurokinin-1 (NK1) receptor antagonist, and ondansetron for their preventive effects on PONV in patients who underwent gynecologic abdominal surgery with patient-controlled epidural analgesia. This prospective, double-blind, randomized study comprised 44 patients who underwent gynecologic abdominal surgery. They were randomly allocated to receive 150 mg intravenous fosaprepitant (n = 24; NKI group) or 4 mg ondansetron (n = 20; ONS group) before anesthesia, which was maintained with volatile anesthetics, remifentanil, fentanyl, and rocuronium. All patients received postoperative fentanyl by patient-controlled epidural anesthesia. The incidence of nausea and vomiting, complete response rate (i.e., no vomiting and no rescue antiemetic use), rescue antiemetic use, nausea score (0-3), and visual analog scale score (VAS 0-10) for pain were recorded at 2, 24, 48, and 72 h after surgery. No (0 %) patient in the NKI group experienced vomiting after surgery; however, 4-6 (20-30 %) of 20 patients in the ONS group experienced vomiting. This difference was significant at 0-24, 0-48, and 0-72 h. During the study period, no significant differences existed between the NK1 and ONS groups in the incidence of PONV, complete response rate, rescue antiemetic use, nausea score, and VAS score for pain. Compared to ondansetron, fosaprepitant more effectively decreased the incidence of vomiting in patients who underwent gynecologic abdominal surgery with patient-controlled epidural analgesia.

    With current literature quoting mortality rates up to 45%, emergency high-risk abdominal surgery has, compared with elective surgery, a significantly greater risk of death and major complications. The Surgical Apgar Score (SAS) is predictive of outcome in elective surgery, but has never been validated exclusively in an emergency setting. A consecutive prospective single-center cohort study of 355 adults undergoing emergency high-risk abdominal surgery between June 2013 and May 2014 is presented. The primary outcome measure was 30-day mortality. Secondary outcome measures were postoperative major complications, defined according to the Clavien-Dindo scale as well as the American College of Surgeons' National Surgical Quality Improvement Program guidelines, and intensive care unit admission. The SAS was calculated postoperatively. Cochran-Armitage test for trend was used to evaluate the incidence of both outcomes. Area under the curve was used to demonstrate the scores' discriminatory power. One hundred eighty-one (51.0%) patients developed minor or no complications. The overall incidence of major complications was 32.7% and the overall death rate was 16.3%. Risk of major complications, death, and intensive care unit admission increased significantly with decreasing SAS (P high-risk abdominal surgery. Despite its predictive value, the SAS cannot in its current version be recommended as a standalone prognostic tool in an emergency setting.

    To determine which abdominal CT findings predict severe fibrosis and post-operative pain relief in chronic pancreatitis (CP). Pre-operative abdominal CTs of 66 patients (mean age 52 ± 12 years, 53 % males) with painful CP who underwent the Whipple procedure (n = 32), Frey procedure (n = 32) or pancreatic head biopsy (n = 2), between 1/2003-3/2014, were evaluated. CT was evaluated for parenchymal calcifications, intraductal calculi, main pancreatic duct dilation (>5 mm), main pancreatic duct stricture, and abnormal side branch(es). The surgical histopathology was graded for fibrosis. CT findings were evaluated as predictors of severe fibrosis and post-operative pain relief using regression and area under receiver operating curve (AUC) analysis. Thirty-eight (58 %) patients had severe fibrosis. Parenchymal calcification(s) were an independent predictor of severe fibrosis (p = 0.03), and post-operative pain relief over a mean follow-up of 1-year (p = 0.04). Presence of >10 parenchymal calcifications had higher predictive accuracy for severe fibrosis than 1-10 parenchymal calcification(s) (AUC 0.88 vs. 0.59, p = 0.003). The predictive accuracy of >10 versus 1-10 parenchymal calcifications increased after adjusting for all other CT findings (AUC 0.89 vs. 0.63, p = 0.01). Parenchymal calcification(s) independently predict severe fibrosis and are significantly associated with post-operative pain relief in CP. The presence of >10 parenchymal calcifications is a better predictor of severe fibrosis than 1-10 parenchymal calcification(s). (orig.)

CT was evaluated for parenchymal calcifications, intraductal calculi, main pancreatic duct dilation (>5 mm), main pancreatic duct stricture, and abnormal side branch(es). The surgical histopathology was graded for fibrosis. CT findings were evaluated as predictors of severe fibrosis and post-operative pain relief using regression and area under receiver operating curve (AUC) analysis. Thirty-eight (58 %) patients had severe fibrosis. Parenchymal calcification(s) were an independent predictor of severe fibrosis (p = 0.03), and post-operative pain relief over a mean follow-up of 1-year (p = 0.04). Presence of >10 parenchymal calcifications had higher predictive accuracy for severe fibrosis than 1-10 parenchymal calcification(s) (AUC 0.88 vs. 0.59, p = 0.003). The predictive accuracy of >10 versus 1-10 parenchymal calcifications increased after adjusting for all other CT findings (AUC 0.89 vs. 0.63, p = 0.01). Parenchymal calcification(s) independently predict severe fibrosis and are significantly associated with post-operative pain relief in CP. The presence of >10 parenchymal calcifications is a better predictor of severe fibrosis than 1-10 parenchymal calcification(s). (orig.)

    Surgical mortality data are collected routinely in high-income countries, yet virtually no low- or middle-income countries have outcome surveillance in place. The aim was prospectively to collect worldwide mortality data following emergency abdominal surgery, comparing findings across countries with a low, middle or high Human Development Index (HDI). This was a prospective, multicentre, cohort study. Self-selected hospitals performing emergency surgery submitted prespecified data for consecutive patients from at least one 2-week interval during July to December 2014. Postoperative mortality was analysed by hierarchical multivariable logistic regression. Data were obtained for 10 745 patients from 357 centres in 58 countries; 6538 were from high-, 2889 from middle- and 1318 from low-HDI settings. The overall mortality rate was 1·6 per cent at 24 h (high 1·1 per cent, middle 1·9 per cent, low 3·4 per cent; P high 4·5 per cent, middle 6·0 per cent, low 8·6 per cent; P surgery (high 74·2 per cent, middle 68·8 per cent, low 60·5 per cent). After adjustment, 30-day mortality remained higher in middle-income (odds ratio (OR) 2·78, 95 per cent c.i. 1·84 to 4·20) and low-income (OR 2·97, 1·84 to 4·81) countries. Surgical safety checklist use was less frequent in low- and middle-income countries, but when used was associated with reduced mortality at 30 days. Mortality is three times higher in low- compared with high-HDI countries even when adjusted for prognostic factors. Patient safety factors may have an important role.

    to evaluate the association between serum levels of procalcitonin and C-reactive protein, on the first 3 postoperative days, and the appearance of postoperative intra-abdominal infection. Prospective observational study including 67 patients operated on for colo-rectal, gastric and pancreatic cancer. Serum levels of procalcitonin and C-reactive protein were analyzed before surgery and daily until the third postoperative day. Values of procalcitonin (PCT) and C-reactive protein (CRP) were recorded as well as their accuracy for detection of postoperative intra-abdominal infection (PIAI). The incidence of postoperative intra-abdominal infection was 13.4%. CRP serum levels at 72h, PCT serum levels at 24, 48 and 72h and the ratio between serum levels of CRP at 72hours and serum levels of CRP at 48hours (CRP D3/CRP D2) were significantly associated with the appearance of postoperative intra-abdominal infection. The highest sensitivity corresponded to PCT at 72hours (88.9%); the highest specificity and positive predictive value corresponded to the ratio CRP D3/CRP D2 (96.49% and 71.4%, respectively); the highest negative predictive value to procalcitonin at 72h and 24h. Serum levels of PCT are significantly associated with the appearance of postoperative intra-abdominal infection. Sensitivity and predictive positive values are low, but negative predictive value is high, even at 24h after surgery. Copyright © 2013 AEC. Published by Elsevier Espana. All rights reserved.

    Postoperative non-cardiac complication rates are as high as 11-28% after high-risk abdominal procedures. Emerging evidence indicates that postoperative cardiac troponin T elevations are associated with adverse outcome in non-cardiac surgery. The aim of this study was to determine the relationship between postoperative high-sensitive cardiac troponin T elevations and non-cardiac complications in patients after major abdominal surgery. This prospective observational single-centre cohort study included patients at risk for coronary artery disease undergoing elective major abdominal surgery. Cardiac troponin was measured before surgery and at day 1, 3, and 7. Multivariable logistic regression analysis was performed to examine the adjusted association for different cut-off concentrations of postoperative myocardial injury and non-cardiac outcome. In 203 patients, 690 high-sensitive cardiac troponin T measurements were performed. Fifty-three patients (26%) had a non-cardiac complication within 30 days after surgery. Hospital mortality was 4% (8/203). An increase in cardiac troponin T concentration ≥100% compared with baseline was a superior independent predictor of non-cardiac postoperative clinical complications (adjusted odds ratio 4.3, 95% confidence interval 1.8-10.1, Phigh-sensitive cardiac troponin T increase ≥100% is a strong predictor of non-cardiac 30 day complications, increased hospital stay and hospital mortality in patients undergoing major abdominal surgery.

    Individualised risk prediction is crucial if targeted pre-operative risk reduction strategies are to be deployed effectively. Radiologically determined sarcopenia has been shown to predict outcomes across a range of intra-abdominal pathologies. Access to pre-operative cross-sectional imaging has resulted in a number of studies investigating the predictive value of radiologically assessed sarcopenia over recent years. This systematic review and meta-analysis aimed to determine whether radiologically determined sarcopenia predicts post-operative morbidity and mortality following abdominal surgery. CENTRAL, EMBASE and MEDLINE databases were searched using terms to capture the concept of radiologically assessed sarcopenia used to predict post-operative complications in abdominal surgery. Outcomes included 30 day post-operative morbidity and mortality, 1-, 3- and 5-year overall and disease-free survival and length of stay. Data were extracted and meta-analysed using either random or fixed effects model (Revman ® 5.3). A total of 24 studies involving 5267 patients were included in the review. The presence of sarcopenia was associated with a significant increase in major post-operative complications (RR 1.61 95% CI 1.24-4.15 p = sarcopenia predicted 1-, 3- and 5-year survival (RR 1.61 95% CI 1.36-1.91 p = sarcopenia may benefit patients undergoing abdominal surgery.

    Up to 93% of patients undergoing abdominal surgery will develop intra-abdominal adhesions with the subsequent morbidity that they represent. Various substances have been tested for the prevention of adhesions with controversial results; the aim of our study is to compare the capability of pirfenidone in adhesion prevention against sodium hyaluronate/carboxymethylcellulose. A randomized, prospective, longitudinal experimental study with Winstar rats. They were divided into 3 groups. The subjects underwent an exploratory laparotomy and they had a 4cm(2) cecal abrasion. The first group received saline on the cecal abrasion, and groups 2 and 3 received pirfenidone and sodium hyaluronate/carboxymethylcellulose respectively. All rats were sacrificed on the 21st day after surgery and the presence of adhesions was evaluated with the modified Granat scale. Simple frequency, central tendency and dispersion measures were recorded. For the statistical analysis we used Fisher's test. To evaluate adhesions we used the Granat's modified scale. The control group had a median adhesion formation of 3 (range 0-4). The pirfenidone group had 1.5 (range 0-3), and the sodium hyaluronate/carboxymethylcellulose group had 0 (range 0-1). There was a statistically significant difference to favor sodium hyaluronate/carboxymethylcellulose against saline and pirfenidone (P<0.009 and P<.022 respectively). The use of sodium hyaluronate/carboxymethylcellulose is effective for the prevention of intra-abdominal adhesions. More experimental studies are needed in search for the optimal adhesion prevention drug. Copyright © 2015 AEC. Publicado por Elsevier España, S.L.U. All rights reserved.

    Morbidity and mortality are increased after urgent surgery for complicated abdominal wall hernia. We analysed prospectively early morbidity and mortality after implementing specific management measures in patients undergoing urgent hernia repair. The study population included 244 patients with complicated abdominal wall hernia requiring surgical repair on an emergency basis over 1-year period. Patients were managed according to a protocol that included specific actions to be implemented in the pre-, intra- and postoperative periods. Outcomes of these patients were compared with those of 402 undergoing similar operations before development of the protocol. Patients in whom acute complication was the first hernia symptom had higher mortality (7.2% vs 2.5%; P = 0.07) and were consulted later than 24 h (49.4% vs 36%; P = 0.044). Patients consulting later than 24 h had higher mortality (8.1% vs 1.4%, P = 0.017). Femoral hernias exhibited specific characteristics and were associated with higher mortality (13% vs 1.6%; P = 0.001). Overall, both groups had similar mortality (4.5% vs 4.1%; P = 0.8); complications (38.8% vs 37.7%; P = 0.2), and bowel resection rates (12.2% vs 11.5%; P = 0.8). Excluding the group of femoral hernias, the measures achieved a lower rate of severe complications (21.2% vs 10.3%; P = 0.04) and a decrease in mortality (2.9% vs 0.6%; P = 0.05) after bowel resection. Specific measures for improvement of management and prevention of complications and mortality were effective in patients without femoral hernia. To reduce mortality, the best applicable measure is early detection and to prioritize the scheduled operation of femoral hernias and those affecting high risk patients. The implementation of preventive and educational programs in high risk patients is essential.

    Decreased scarring is an advantage of minimally invasive surgery. The new experimental technique of natural orifice transluminal surgery (NOTES) aims at totally scarless surgery. We examined the general attitudes of patients and unaffected persons towards scarless surgery. We used a 7-item questionnaire in structured interviews with hospital visitors, following detailed standardized explanation of terms used and of possible complications, to groups of 10 participants, during an "open ward" day. A visual analog scale (VAS) from 1 (none) to 10 (very much) was used for all but one item. Questions concerned the importance of cosmetic results in abdominal surgery, satisfaction regarding existing scars, hypothetical acceptance of increased risk as a trade-off for the absence of scars, and other issues. Data were analyzed for participants overall, and for three age groups and both sexes. 292 participants (male : female 1 : 1; mean age 43 years) completed the questionnaire. Cosmetic issues were rated as important (median 8), but acceptance of existing scars was also high in those affected (median 8, n=68). Approval of scarless surgery decreased with a presumed risk increase (from score 9 down to score 5), and overall an increase in risk of 10 % was judged to be acceptable as a trade-off for total absence of scarring. Younger people tended to be less satisfied with scars, but were also less inclined than older people to accept higher surgical risk in this hypothetical context. People generally seem to favor scarless abdominal surgery, even with some increase in risk.

    Low health literacy is known to adversely affect health outcomes in patients with chronic medical conditions. To our knowledge, the association of health literacy with postoperative outcomes has not been studied in-depth in a surgical patient population. To evaluate the association of health literacy with postoperative outcomes in patients undergoing major abdominal surgery. From November 2010 to December 2013, 1239 patients who were undergoing elective gastric, colorectal, hepatic, and pancreatic resections for both benign and malignant disease at a single academic institution were retrospectively reviewed. Patient demographics, education, insurance status, procedure type, American Society of Anesthesiologists status, Charlson comorbidity index, and postoperative outcomes, including length of stay, emergency department visits, and hospital readmissions, were reviewed from electronic medical records. Health literacy levels were assessed using the Brief Health Literacy Screen, a validated tool that was administered by nursing staff members on hospital admission. Multivariate analysis was used to determine the association of health literacy levels on postoperative outcomes, controlling for patient demographics and clinical characteristics. The association of health literacy with postoperative 30-day emergency department visits, 90-day hospital readmissions, and index hospitalization length of stay. Of the 1239 patients who participated in this study, 624 (50.4%) were women, 1083 (87.4%) where white, 96 (7.7%) were black, and 60 (4.8%) were of other race/ethnicity. The mean (SD) Brief Health Literacy Screen score was 12.9 (SD, 2.75; range, 3-15) and the median educational attainment was 13.0 years. Patients with lower health literacy levels had a longer length of stay in unadjusted (95% CI, 0.95-0.99; P = .004) and adjusted (95% CI, 0.03-0.26; P = .02) analyses. However, lower health literacy was not significantly associated with increased rates of 30-day

    Since 1986, 32 patients with metastatic colorectal cancer have undergone second-look radioimmunoguided surgery (RIGS system). The primary tumor was located in the right and transverse colon in 11 patients, left and sigmoid colon in 16, and rectum in five. The carcinoembryonic antigen level was elevated in 30 patients (94%); all patients underwent a computed tomographic scan of the abdomen and pelvis. The overall sensitivity of the computed tomographic scan was 41% (abdomen other than liver, 27%; liver, 58%; and pelvis, 22%). The RIGS system identified recurrent tumor in 81% of the patients. The most common site of metastasis was the liver (41%), independent of the primary location. Local/regional recurrences alone accounted for 40% of all recurrences. In six patients (18%), recurrent tumor was found only with the RIGS system. The RIGS system is more dependable in localizing clinically obscure metastases than other methods, and carcinoembryonic antigen testing remains the most accurate preoperative method to indicate suspected recurrences

    This study aimed to evaluate the efficacy of low-level laser therapy (LLLT) and light-emitting diodes (LEDs) for reducing pain in hyperglycemic and normoglycemic patients who underwent coronary artery bypass surgery with internal mammary artery grafts. This study was conducted on 120 volunteers who underwent elective coronary artery bypass graft (CABG) surgery. The volunteers were randomly allocated to four different groups of equal size (n = 30): control, placebo, LLLT [λ = 640 nm and spatial average energy fluence (SAEF) = 1.06 J/cm(2)], and LED (λ = 660 ± 20 nm and SAEF = 0.24 J/cm(2)). Participants were also divided into hyperglycemic and normoglycemic subgroups, according to their fasting blood glucose test result before surgery. The outcome assessed was pain during coughing by a visual analog scale (VAS) and the McGill Pain Questionnaire. The patients were followed for 1 month after the surgery. The LLLT and LED groups showed a greater decrease in pain, with similar results, as indicated by both the VAS and the McGill questionnaire (p ≤ 0.05), on the 6th and 8th postoperative day compared with the placebo and control groups. The outcomes were also similar between hyperglycemic and normoglycemic patients. One month after the surgery, almost no individual reported pain during coughing. LLLT and LED had similar analgesic effects in hyperglycemic and normoglycemic patients, better than placebo and control groups.

    Dex medetomidine is a highly selective α2 agonist with anesthetic, analgesic and sympatholytic properties. Its neuromuscular effects in humans are unknown. This study evaluates the effect of dex medetomidine on neuromuscular block and hemodynamics during thiopental/ isoflurane anesthesia for patients with complex abdominal or pelvic surgery. Patients and methods: During thiopental/isoflurane anesthesia, the rocuronium infusion rate was adjusted in 20 complex surgery patients to maintain a stable first response (T1) in the train of four sequence of 50% ± 3 of the pre-rocuronium value. Dex medetomidine was then administered by infusion pump, targeting a plasma dex medetomidine concentration of 0.6 ng/dL for 45 min. The evoked mechanical responses of the adductor pollicis responses (T1 response and T4/T1 ratio), systolic blood pressure, diastolic blood pressure and heart rate (HR) were measured during the dex medetomidine infusion using repeated measures analysis of variance. Plasma levels ranged from 0.73 to 1.38 ng/mL. Results: T1 values decreased during the infusion from 55(ρ2 to 38±9 ((ρ< 0.05). T4/Tl values did not change during the infusion. Dex medetomidine increased SBP (ρ< 0.001) and decreased HR ((ρ< 0.05) (10 min median values) during the infusion compared with values before the infusion. This study demonstrated that dex medetomidine decreased T1, increased SBP and decreased HR during thiopental/isoflurane anesthesia. Conclusion: We conclude that dex medetomidine induced direct vasoconstriction may alter pharmacokinetics of rocuronium, therefore increasing plasma rocuronium concentration. Although these effects were statistically significant, further studies should be held for understanding and characterizing the peripheral vasoconstrictive effects of a2 agonists that allow better management and determination of drug dosing regimens

    To evaluate the vital capacity after two chest therapy techniques in patients undergoing abdominal surgical. A prospective randomized study carried out with patients admitted to the Intensive Care Unit after abdominal surgery. We checked vital capacity, muscular strength using the Medical Research Council scale, and functionality with the Functional Independence Measure the first time the patient was breathing spontaneously (D1), and also upon discharge from the Intensive Care Unit (Ddis). Between D1 and Ddis, respiratory therapy was carried out according to the randomized group. We included 38 patients, 20 randomized to Positive Intermittent Pressure Group and 18 to Volumetric Incentive Spirometer Group. There was no significant gain related to vital capacity of D1 and Ddis of Positive Intermittent Pressure Group (mean 1,410mL±547.2 versus 1,809mL±692.3; p=0.979), as in the Volumetric Incentive Spirometer Group (1,408.3mL±419.1 versus 1,838.8mL±621.3; p=0.889).

    Aminophylline can elicit thermogenesis in rats or increase metabolic rate during cold stress in lambs. We tested the hypothesis that aminophylline would reduce the change in core body temperature during laparoscopic abdominal surgery requiring pneumoperitoneum. Fifty patients were randomly divided into an aminophylline group (n=25) and a saline control group (n=25). Esophageal temperature, index finger temperature, and hemodynamic variables, such as mean blood pressure and heart rate, were measured every 15 min during sevoflurane anesthesia. In the aminophylline group, esophageal temperatures at T45 (36.1±0.38 vs. 35.7±0.29, P=0.024), T60 (36.0±0.39 vs. 35.6±0.28, P=0.053), T75 (35.9±0.34 vs. 35.5±0.28, P=0.025), T90 (35.8±0.35 vs. 35.3±0.33, P=0.011), and T105 (35.8±0.36 vs. 35.1±0.53, P=0.017) and index finger temperatures at T15 (35.8±0.46 vs. 34.9±0.33, Ptemperature through a thermogenic effect, despite reduced peripheral thermoregulatory vasoconstriction.

    In patients with perforated peptic ulcer, surgical delay has recently been shown to be a critical determinant of survival. The aim of the present population-based cohort study was to evaluate the association between surgical delay by hour and mortality in high-risk patients undergoing emergency abdominal surgery in general. All in-patients aged ≥ 18 years having emergency abdominal laparotomy or laparoscopy performed within 48 h of admission between 1 January 2009 and 31 December 2010 in 13 Danish hospitals were included. Baseline and clinical data, including surgical delay and 90-day mortality were collected. The crude and adjusted association between surgical delay by hour and 90-day mortality was assessed by binary logistic regression. A total of 2803 patients were included. Median age (interquartile range [IQR]) was 66 (51-78) years, and 515 patients (18.4%) died within 90 days of surgery. Over the first 24 h after hospital admission, each hour of surgical delay beyond hospital admission was associated with a median (IQR) decrease in 90-day survival of 2.2% (1.9-3.3%). No statistically significant association between surgical delay by hour and 90-day mortality was shown; crude and adjusted odds ratio with 95% confidence interval 1.016 (1.004-1.027) and 1.003 (0.989-1.017), respectively. Sensitivity analyses confirmed the primary finding. In the present population-based cohort study of high-risk patients undergoing emergency abdominal surgery, no statistically significant adjusted association between mortality and surgical delay was found. Additional research in diagnosis-specific subgroups of high-risk patients undergoing emergency abdominal surgery is warranted.

    Blinding is a measure in randomized controlled trials (RCT) to reduce detection and performance bias. There is evidence that lack of blinding leads to overestimated treatment effects. Because of the physical component of interventions, blinding is not easily applicable in surgical trials. This is a protocol for a systematic review and empirical study about actual impact on outcomes and future potential of blinding in general and abdominal surgery RCT. A systematic literature search in CENTRAL, MEDLINE and Web of Science will be conducted to locate RCT between 1996 and 2015 with a surgical intervention. General study characteristics and information on blinding methods will be extracted. The risk of performance and detection bias will be rated as low, unclear or high according to the Cochrane Collaboration's tool for assessing risk of bias. The main outcome of interest will be the association of a high risk of performance or detection bias with significant trial results and will be tested at a level of significance of 5 %. Further, trials will be meta-analysed in a Mantel-Haenszel model comparing trials with high risk of bias to other trials at a level of significance of 5 %. Detection and performance bias distort treatment effects. The degree of such bias in general and abdominal surgery is unknown. Evidence on influence of missing blinding would improve critical appraisal and conduct of general and abdominal surgery RCT. PROSPERO 2015: CRD42015026837.

    The aim of this study was to assess the impact of personalized prehabilitation on postoperative complications in high-risk patients undergoing elective major abdominal surgery. Prehabilitation, including endurance exercise training and promotion of physical activity, in patients undergoing major abdominal surgery has been postulated as an effective preventive intervention to reduce postoperative complications. However, the existing studies provide controversial results and show a clear bias toward low-risk patients. This was a randomized blinded controlled trial. Eligible candidates accepting to participate were blindly randomized (1:1 ratio) to control (standard care) or intervention (standard care + prehabilitation) groups. Inclusion criteria were: i) age >70 years; and/or, ii) American Society of Anesthesiologists score III/IV. Prehabilitation covered 3 actions: i) motivational interview; ii) high-intensity endurance training; and promotion of physical activity. The main study outcome was the proportion of patients suffering postoperative complications. Secondary outcomes included the endurance time (ET) during cycle-ergometer exercise. We randomized 71 patients to the control arm and 73 to intervention. After excluding 19 patients because of changes in the surgical plan, 63 controls and 62 intervention patients were included in the intention-to-treat analysis. The intervention group enhanced aerobic capacity [ΔET 135 (218) %; P high-risk candidates for elective major abdominal surgery, which can be explained by the increased aerobic capacity.

    To assess the effectiveness and safety of perioperative growth hormone (GH) in patients undergoing abdominal surgery. We searched the following electronic databases: MEDLINE, EMBASE, the Cochrane Controlled Trials Register, Chinese Bio-medicine Database. The search was undertaken in February 2003. No language restrictions were applied. Randomized controlled trials (RCT) comparing GH with placebo in patients undergoing abdominal surgery were extracted and evaluated. Methodological quality was evaluated using the Jadad scale. Eighteen trials involving 646 patients were included. The combined results showed that GH had a positive effect on improving postoperative nitrogen balance (standardized mean difference (SMD) = 3.37, 95%CI (2.46, 4.27), P<0.00001), and decreasing the length of hospital stay (weighted mean difference (WMD) = -2.07, 95%CI (-3.03, -1.11), P = 0.00002), and reducing the duration of postoperative fatigue syndrome (SMD = -1.83, 95%CI (-2.37, -1.30), P<0.00001), but it could increase blood glucose levels (WMD = 0.91, 95%CI (0.56, 1.25), P<0.00001). GH for patients undergoing abdominal surgery is effective and safe, if blood glucose can be controlled well. Further trials are required with a sufficient size to account for clinical heterogeneity and to measure other important outcomes such as infection, morbidity, mortality, fluid retention, immunomodulatory effects, and tumor recurrence.

    Giant hiatal hernia (GHH) comprises 5% of hiatal hernia and is associated with significant complications. The traditional operative procedure, no matter transthoracic or transabdomen repair of giant hiatal hernia, is characteristic of more invasion and more complications. Although laparoscopic repair as a minimally invasive surgery is accepted, a part of patients can not tolerate pneumoperitoneum because of combination with cardiopulmonary diseases or severe posterior mediastinal and neck emphesema during operation. The aim of this article was to analyze our experience in gasless laparoscopic repair with abdominal wall lifting to treat the giant hiatal hernia. We performed a retrospective review of patients undergoing gasless laparoscopic repair of GHH with abdominal wall lifting from 2012 to 2015 at our institution. The GHH was defined as greater than one-third of the stomach in the chest. Gasless laparoscopic repair of GHH with abdominal wall lifting was attempted in 27 patients. Mean age was 67 years. The results showed that there were no conversions to open surgery and no intraoperative deaths. The mean duration of operation was 100 min (range: 90-130 min). One-side pleura was injured in 4 cases (14.8%). The mean postoperative length of stay was 4 days (range: 3-7 days). Median follow- up was 26 months (range: 6-38 months). Transient dysphagia for solid food occurred in three patients (11.1%), and this symptom disappeared within three months. There was one patient with recurrent hiatal hernia who was reoperated on. Two patients still complained of heartburn three months after surgery. Neither reoperation nor endoscopic treatment due to signs of postoperative esophageal stenosis was required in any patient. Totally, satisfactory outcome was reported in 88.9% patients. It was concluded that the gasless laparoscopic approach with abdominal wall lifting to the repair of GHH is feasible, safe, and effective for the patients who cannot tolerate the pneumoperitoneum.

    Readmission rates after operative procedures are used increasingly as a measure of hospital care quality. Patient access to care may influence readmission rates. The objective of this study was to determine the relationship between patient cost-sharing, insurance arrangements, and the risk of postoperative readmissions. Using the MarketScan Research Database (n = 121,002), we examined privately insured, nonelderly patients who underwent abdominal surgery in 2010. The main outcome measures were risk-adjusted unplanned readmissions within 7 days and 30 days of discharge. Odds of readmissions were compared with multivariable logistic regression models. In adjusted models, $1,284 increase in patient out-of-pocket payments during index admission (a difference of one standard deviation) was associated with 19% decrease in the odds of 7-day readmission (odds ratio [OR] 0.81, 95% confidence interval [CI] 0.78-0.85) and 17% decrease in the odds of 30-day readmission (OR 0.83, 95% CI 0.81-0.86). Patients in the noncapitated point-of-service plans (OR 1.19, 95% CI 1.07-1.33), preferred provider organization plans (OR 1.11, 95% CI 1.03-1.19), and high-deductible plans (OR 1.12, 95% CI 1.00-1.26) were more likely to be readmitted within 30 days compared with patients in the capitated health maintenance organization and point-of-service plans. Among privately insured, nonelderly patients, increased patient cost-sharing was associated with lower odds of 7-day and 30-day readmission after abdominal surgery. Insurance arrangements also were significantly associated with postoperative readmissions. Patient cost sharing and insurance arrangements need consideration in the provision of equitable access for quality care. Copyright © 2016 Elsevier Inc. All rights reserved.

    Dopexamine has been shown to reduce both mortality and morbidity in major surgery when it is used as part of a protocol to increase oxygen delivery in the perioperative period. A European multicenter study has examined the use of dopexamine in patients undergoing major abdominal surgery, showing a trend toward improved survival and reduced complications in high-risk patients when receiving low-dose dopexamine (0.5 μg · kg(-1) · min(-1)). A reduced oxygen uptake at the anaerobic threshold (AT) has been shown to confer a significant risk of mortality in patients undergoing major abdominal surgery and allows objective identification of a high-risk operative group. In this study, we assessed the effects of low-dose dopexamine on morbidity after major abdominal surgery in patients who were at increased risk by virtue of a reduced AT. Patients undergoing elective major colorectal or urological surgery who had an AT of surgery, a radial arterial cannula was placed and attached to an Edwards Lifesciences FloTrac/Vigileo system for measuring cardiac output. Patients were given a 250-mL bolus of Voluven (6% hydroxyethyl starch 130/0.4 in 0.9% sodium chloride) until the stroke volume no longer increased by 10%, then received either dopexamine (0.5 μg · kg(-1) · min(-1)) or saline 0.9% for 24 hours. During surgery, fluid boluses of Voluven were given if the stroke volume variation was >10%. No crystalloid was given during surgery. A standardized postoperative fluid regime with Hartmann solution was prescribed at 1.5 mL · kg(-1) · h(-1) for 24 hours. The primary outcome measure was postoperative morbidity measured by the Postoperative Morbidity Survey. One hundred twenty-four patients were recruited over a 23-month period. The incidence of morbidity as measured by the Postoperative Morbidity Survey on day 5 was 55% in the control group versus 47% in the dopexamine group (P = 0.14). There was no significant reduction in morbidity on any measured postoperative day

    Surgical site infection (SSI) remains to be one of the most frequent infectious complications following abdominal surgery. Prophylactic intra-operative wound irrigation (IOWI) before skin closure has been proposed to reduce bacterial wound contamination and the risk of SSI. However, current recommendations on its use are conflicting especially concerning antibiotic and antiseptic solutions because of their potential tissue toxicity and enhancement of bacterial drug resistances. To analyze the existing evidence for the effect of IOWI with topical antibiotics, povidone-iodine (PVP-I) solutions or saline on the incidence of SSI following open abdominal surgery, a systematic review and meta-analysis of randomized controlled trials (RCTs) was carried out according to the recommendations of the Cochrane Collaboration. Forty-one RCTs reporting primary data of over 9000 patients were analyzed. Meta-analysis on the effect of IOWI with any solution compared to no irrigation revealed a significant benefit in the reduction of SSI rates (OR = 0.54, 95 % confidence Interval (CI) [0.42; 0.69], p < 0.0001). Subgroup analyses showed that this effect was strongest in colorectal surgery and that IOWI with antibiotic solutions had a stronger effect than irrigation with PVP-I or saline. However, all of the included trials were at considerable risk of bias according to the quality assessment. These results suggest that IOWI before skin closure represents a pragmatic and economical approach to reduce postoperative SSI after abdominal surgery and that antibiotic solutions seem to be more effective than PVP-I solutions or simple saline, and it might be worth to re-evaluate their use for specific indications.

    Porcine small intestinal submucosa (SIS) is used as a biological implant for abdominal wall hernia repair to facilitate wound healing and augment local tissue strength. This prospective, randomized, blinded study evaluated local pain control provided by bupivacaine adsorbed to SIS for repair of acutely created abdominal wall full thickness muscle/fascial defects in ferrets. Eighteen healthy ferrets were randomly and equally assigned to three groups: (1) SIS with bupivacaine subjected to surgery, (2) SIS with no bupivacaine subjected to surgery, and (3) anesthesia only control group. Ferrets in groups 1 and 2 were anesthetized with butorphanol and sevoflurane for the surgery. Control ferrets were anesthetized in the same fashion for the same duration without surgery. Behavior and pain were evaluated in all ferrets by behavioral observation, algometer, and palpometer measurements, and heart and respiratory rates each obtained before surgery and at various intervals for 96 h after surgery. When pain reached a predetermined threshold, buprenorphine was used as a rescue analgesic. The serum and combined tissue concentrations of bupivacaine were analyzed. Overall, the palpometer testing was better tolerated in the bupivacaine treated SIS group than by the untreated SIS group (P = 0.04). There was an observed physiologically significant difference in algometer and other palpometer readings as well as heart and respiratory rates. All ferrets in the untreated SIS group were rescued while 33% of the SIS-bupivacaine groups were rescued (P pain relief over 2-4 days with no clinical adverse effects observed in the ferrets.

    Surgical site infection (SSI) is one of the main causes of morbidity and death after surgical intervention. The use of physical barriers, including gloves, drapes, and gowns to reduce SSI after abdominal surgery is long-standing practice. The aim of this systematic review and meta-analysis was to determine the efficacy of ring incision retractors in reducing the risk of SSI in abdominal surgery. PubMed, CINAHL, the Cochrane randomized controlled trials (RCTs) Central Register, and the ISRCTN registry were searched for RCTs in which ring retractors were utilized to reduce SSI in abdominal surgery. The PRISMA guidelines and RevMan 5.3 were used for study selection and analysis. Additional subgroup analyses were performed, including trials using incision class (clean, clean-contaminated contaminated, and dirty) and trials that used the U.S. Centers for Disease Control and Prevention's SSI definition in their protocol. A total of 19 RCTs inclusive of 4,229 patients were included. The utility of ring retractors in reducing SSI was suggested by an overall risk ratio of 0.62 (95% confidence interval 0.48-0.81). However, study heterogeneity caused by differences in effect size between individual RCTs, the non-standardized utilization of concomitant measures to reduce SSI, and an overall lack of high-quality trials was found. A reduction in SSI incidence with the use of ring retractors is suggested by the findings. However, this result must be treated with caution because in addition to some old trials poor quality and the large number of factors affecting SSI, there were substantial differences between trials in effect sizes in statistical heterogeneity. Further RCTs are needed to confirm this provisional finding.

    To compare the diagnostic accuracy of ultrasonography (US), F18-fluorodeoxyglucose positron emission tomography/CT (PET/CT), contrast enhanced CT (CECT), serum anti-thyroid antibody for detecting Hashimoto's thyroiditis in thyroid cancer patients who underwent neck surgery. A total of 150 patients with suspicious for thyroid cancer, who had previously undergone US guided needle aspiration of thyroid, were evaluated with the use of US, PET/CT, CECT and serum anti-thyroid antibody. The four studies were performed within two months before neck surgery. Hashimoto's thyroiditis was confirmed by histopathological results. The diagnostic accuracy of US, PET/CT, CECT and serum anti-thyroid antibody were calculated statistically. Hashimoto's thyroiditis was diagnosed in 51 out of the 150 patients, following neck surgery. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of US were 76.5%, 92.9%, 84.8%, 88.5%, and 87.3%, respectively. The corresponding values of PET/CT were 37.3%, 96.0%, 82.6%, 74.8%, and 76.0%, and CECT were 62.7%, 89.9%, 76.2%, 82.4%, and 80.7%, and serum anti-thyroid antibody level were 90.2%, 93.9%, 88.5%, 94.9%, and 92.7%, respectively. McNemar test revealed significant difference among PET/CT and others, but no significant differences among US, CECT and serum anti-thyroid antibody. Overall, serum anti-thyroid antibody showed most accurate diagnostic performance. In detecting Hashimoto's thyroiditis, serum anti-thyroid antibody showed higher diagnostic accuracy than others. US also showed relatively high diagnostic accuracy.

    Acute heparin-induced thrombocytopenia (HIT) patients present a myriad of anticoagulation management challenges, in clinical settings where unfractionated heparin (UFH) is the traditional drug of choice. UFH use in cardiac surgery is a known entity that has been subject to rigorous research. Research has, thus, led to its unparalleled use and the development of well-established protocols for cardiac surgery. In comparison to UFH, bivalirudin use for acute HIT patients requiring urgent cardiac surgery with cardiopulmonary bypass (CPB) is still in its infancy. We describe the tailored post-CPB management of refractory bleeding in a 65-year-old infective endocarditis, acute HIT patient with renal failure who underwent urgent aortic valve replacement and mitral valve repair with bivalirudin anticoagulation. A management approach that entailed a combination of continuous venovenous haemofiltration (CVVH), 4-Factor prothrombin complex concentrate (PCC) (Beriplex), recombinant factor VIIa (rFactor VIIa) and desmopressin (DDAVP) were consecutively used post-operatively in theatre. Based on this case study experience, two modifications to institutional protocols are recommended. The first is the use of CVVH in theatre to eliminate bivalirudin in renal failure patients or in patients where bivalirudin elimination is prolonged. Secondly, a 'rescue therapy/intervention' algorithm for the swift identification of refractory bleeding post-CPB is also recommended. Rescue therapy agents, such as a 4-Factor PCCs and rFactor VIIa, should be incorporated into the protocol after a robust evidence-based search and agreement with the haematologist. The aim of these recommendations is to reduce the risk of bleeding associated with bivalirudin use for inexperienced institutions and experienced institutions alike, until larger randomized, controlled studies provide more in-depth knowledge to expand our clinical practice.

    Acute renal failure (ARF) often complicates the postoperative period of patients undergoing orthotopic liver transplantation (OLT); it is habitually associated with high mortality rates. Similarly, patients undergoing major nonelective abdominal surgery are prone to ARF because of their frequent preexistent morbidities, abdominal sepsis, and needed for extended surgical procedures. The aim of this study was to evaluate the incidence of ARF and use of renal replacement therapy (RRT) among OLT versus nonelective abdominal surgery patients and associations with clinical outcomes. We studied all the patients admitted to a surgical intensive care unit (ICU) from January 2008 to December 2009 after OLT or nonelective abdominal surgery. The inclusion criteria were an ICU stay of at least 48 hours and without prior end-stage renal failure. OLT patients (n=84) were younger and less severly ill than surgery patients (n=60). ARF occurrence was lower among the OLT (29%) than the surgery group (47%) requiring RRT in 71% and 53% of patients due to ARF, respectively. The ICU mortality of ARF patients in both groups (29% OLT and 51% surgery) were greater than among subjects without ARF (2% and 6%). The occurrence of ARF is common among these two patient groups, and associated with increased risk of death among in surgery (+45%) versus in OLT (+27%) patients. Copyright © 2011 Elsevier Inc.

    The optimal intravenous fluid regimen for patients undergoing major abdominal surgery is unclear. However, results from many small studies suggest a restrictive regimen may lead to better outcomes. A large, definitive clinical trial evaluating perioperative fluid replacement in major abdominal surgery, therefore, is required. We designed a pragmatic, multicentre, randomised, controlled trial (the RELIEF trial). A total of 3000 patients were enrolled in this study and randomly allocated to a restrictive or liberal fluid regimen in a 1:1 ratio, stratified by centre and planned critical care admission. The expected fluid volumes in the first 24 hour from the start of surgery in restrictive and liberal groups were ≤3.0 L and ≥5.4 L, respectively. Patient enrolment is complete, and follow-up for the primary end point is ongoing. The primary outcome is disability-free survival at 1 year after surgery, with disability defined as a persistent (at least 6 months) reduction in functional status using the 12-item version of the World Health Organisation Disability Assessment Schedule. The RELIEF trial has been approved by the responsible ethics committees of all participating sites. Participant recruitment began in March 2013 and was completed in August 2016, and 1-year follow-up will conclude in August 2017. Publication of the results of the RELIEF trial is anticipated in early 2018. ClinicalTrials.gov identifier NCT01424150. Published by the BMJ Publishing Group Limited.

    Full Text Available Ischemic-reperfusion injury (IRI is defined as tissue damage, organ dysfunction or failure developed in the course of inflammatory response following ischemia and reperfusion (IR. Abdominal aortic aneurysm (AAA repair required IR of distal parts of the body carries a risk of organ injury and postoperative mortality of between 4% and 12%. The aim of this study was the evaluation of IL-12 serum level during AAA repair in relation to IR. Blood samples were taken before surgery (Preop, before aortic unclamping (Pre-Xoff, 90 min after unclamping (90 min-Xoff and 24 h after surgery (Postop from 37 AAA patients; and before surgery (Preop, at 90 min of surgery (90 min-surg, at 180 min of surgery (180 min-surg and 24 h after operation (stop from ten patients scheduled for elective surgery of lumbar discopathy (SC; and once from ten healthy controls. IL-12 was measured using the ELISA technique. Preoperative IL-12 was higher in AAA (0.21 pg/ml and SC (0.31 pg/ml patients than in controls (0.05 pg/ml. A significant decrease in IL-12 (0.09 pg/ml was observed at 90 min-Xoff in comparison to the preoperative value in AAA but not in the SC group. 24 h after surgery, IL-12 levels were still low in the AAA group (0.13 pg/ml, and nonsignificantly surpassed the preoperative value in the SC group (0.36 pg/ml. We conclude that operative injury was associated with increased IL-12 levels, and IR with decreased IL-12 levels. Diminished IL-12 during AAA repair might be associated with a higher risk of postoperative complications, but this needs further evaluation.

    Post traumatic anterior abdominal wall hernia can be ignored in emergency settings. We here report the case of a 32-year-old patient with a BMI of 30 kg/m 2 , suffering from anterior abdominal wall hernia as a result of a road accident. This lesion wasn't detected during clinical examination. Abdominal tomodensitometry showed a defect of 8 cm in the anterior abdominal wall. The patient underwent surgery during which a musculoaponeurotic defect of 12 cm was detected. The repair was carried out using interrupted suture. The postoperative course was marked by a secondarily infected skin necrosis. The evolution was satisfactory after directed cicatrization. At 3 months postoperatively the patient was doing well with a healed wound and a strong abdominal wall.

    Postoperative pleural-pulmonary changes (PPC) are very common following elective abdominal surgery, resolving without clinical manifestations in most patients. The incidence and risk factors associated are unknown. Objective: to determine the incidence of PPC and possible association with risk factors using computerized tomography (CT). Material and method: thirty seven patients submitted to elective abdominal surgery were prospectively analyzed using CT performed in the preoperative period and 48 hours after surgery. The PPC was scored from 0 to III. The risk factors evaluated were: age, sex, obesity, smoking history, alcoholism, comorbid conditions, cancer, ASA classification, duration of surgery, surgical incision type and number of days of hospitalization. Results: Pleura effusion was detected by CT in 70.3% (26/37) of the patients and pulmonary atelectasis in 75.5% (28/37). Grade I and II PPC was found in 59.5% (22/37) of the patients and grade III in 21.6% (8/37). Two (5.4%) of these patients developed serious pulmonary complications whereas one patient died. Surgery due to cancer, class ASA >2, longitudinal incision and > 15 cm showed statistical significance and were associated with pleural effusion. The hospitalization was over 2.4 longer for patients with PPC. Conclusion: PPC is frequently seen in patients submitted to abdominal surgery. The use of the CT for the detection of pulmonary atelectasis and pleural effusion proved to be effective. Most cases of PPC are self-limited, resolving without symptoms. (author)

    Damage control surgery (DCS) was developed to manage exsanguinating trauma patients, but is increasingly applied to the management of peritoneal sepsis and abdominal catastrophes. Few manuscripts compare the outcomes of these surgeries on disparate patient populations. A multi-institutional three group propensity score matched case cohort study comparing penetrating trauma (PT-DCS), blunt trauma (BT-DCS), and intraperitoneal sepsis (IPS-DCS) was performed comparing patients treated with DSC between 2008 and 2013. Propensity scoring was performed using demographic and presenting physiologic data. Four hundred and twelve patients were treated with DCS across two institutions. Propensity matching for age, gender, and initial Acute Physiology and Chronic Health Evaluation II score 80 identified 80 patients per group for comparison. Rate of primary fascial closure was lowest in the IPS-DCS group, and highest in the penetrating trauma DCS group. Intra-abdominal complication rates were highest in the IPS-DCS group. IPS-DCS had increased time to definitive closure compared with the other two groups (RR 1.8; 1.3-2.2; P eight days were more than twice the risk of death at 90 days across all groups.

    Surgical site infection is one of the most common postoperative complications after gastroenterologic surgery. This study investigated the effect of triclosan-coated sutures in decreasing the incidence of surgical site infections after abdominal wall closure in gastroenterologic surgery. A prospective, double-blind, randomized, controlled parallel adaptive group-sequential superiority trial was conducted from March 2014 to March 2017 in a single center. Eligible patients were those who underwent gastroenterologic surgery. Patients were allocated randomly to receive either abdominal wall closure with triclosan-coated sutures (the study group) or sutures without triclosan (the control group). The primary end point was the incidence of superficial or deep surgical site infections within 30 days after operation. This study was registered with the University Hospital Medical Information Network-Clinical Trials Registry (http://www.umin.ac.jp/ctr/), identification number UMIN000013054. A total of 1,013 patients (study group, 508 patients; control group, 505 patients) were analyzed by a modified intention-to-treat approach. The wounds in 990 (97.7%) of the 1,013 patients were classified as clean-contaminated. The primary end point (incidence of superficial or deep surgical site infections) was 35 (6.9%) of 508 patients in the study group and 30 (5.9%) of 505 in the control group. The incidence of surgical site infections did not differ markedly between the 2 groups (95% confidence interval: 0.686-2.010, P = .609). Of the 65 infections, 42 (64.6%) were superficial surgical site infections, with similar frequencies in the 2 groups, and 23 (35.4%) were deep surgical site infections, again with similar frequencies in the 2 groups. Triclosan-coated sutures did not decrease the incidence of surgical site infections after abdominal wall closure in gastroenterologic surgery. Copyright © 2017 Elsevier Inc. All rights reserved.

  2. Abdominal trauma

    Abdominal injury is an important cause of morbidity and mortality in childhood. Ten percent of trauma-related deaths are due to abdominal injury. Thousands of children are involved in auto accidents annually; many suffer severe internal injury. Child abuse is a second less frequent but equally serious cause of internal abdominal injury. The descriptions of McCort and Eisenstein and their associates in the 1960s first brought to attention the frequency and severity of visceral injury as important manifestations of the child abuse syndrome. Blunt abdominal trauma often causes multiple injuries; in the past, many children have been subjected to exploratory surgery to evaluate the extent of possible hidden injury. Since the advent of noninvasive radiologic imaging techniques including radionuclide scans and ultrasound and, especially, computed tomography (CT), the radiologist has been better able to assess (accurately) the extent of abdominal injury and thus allow conservative therapy in many cases. Penetrating abdominal trauma occurs following gunshot wounds, stabbing, and other similar injury. This is fortunately, a relatively uncommon occurrence in most pediatric centers and will not be discussed specifically here, although many principles of blunt trauma diagnosis are valid for evaluation of penetrating abdominal trauma. If there is any question that a wound has extended intraperitonelly, a sinogram with water-soluble contrast material allows quick, accurate diagnosis. The presence of large amounts of free intraperitoneal gas suggests penetrating injury to the colon or other gas-containing viscus and is generally considered an indication for surgery

    Many adverse events occur due to poor communication between surgical and anesthesia unit personnel. The aim of this study was to identify strategies to reduce risks unveiled by a national survey on patient safety. During 2011-2015, specially trained survey teams visited the surgery departments at Swedish hospitals and documented routines concerning safety in abdominal surgery. The reports from the first seventeen visits were reviewed by an independent group in order to extract findings related to routines in communication between anesthesia and surgical unit personnel. In general, routines regarding preoperative risk assessment were safe and well- coordinated. On the other hand, routines regarding medication prior to surgery, reporting between the different units, and systems for reporting and providing feedback on adverse events were poor or missing. Strategies with highest priority include: 1. a uniform national health declaration form; 2. consistent use of admission notes; 3. systems for documenting all important medical information, that is accessible to everyone; 4. a multidisciplinary forum for the evaluation of high-risk patients; 5. weekly and daily scheduling of surgical programs; 6. application of the WHO check list; 7. open dialog during surgery; 8. reporting based on SBAR; 9. oral and written reports from the surgeon to the postoperative unit; and 10. combined mortality and morbidity conferences. One repeatedly occurring hazard endangering patient safety was related to communication between surgical and anesthesia unit personnel. Strategies to reduce this hazard are suggested, but further research is required to test their effectiveness.

    The increased intracranial pressure can significantly complicate the perioperative period in major abdominal surgery, increasing the risk of complications, the length of recovery from the surgery, worsening the outcome. Epidural anesthesia has become a routine component of abdominal surgery, but its use in patients with increased intracranial pressure remains controversial. The goal of the study was to evaluate the safety and efficacy of epidural anesthesia, according to monitoring of intracranial pressure in patients with increased intracranial pressure. The study includes 65 surgical patients who were routinely undergone the major abdominal surgery under combined epidural/general anesthesia. Depending on the initial ICP all patients were divided into 2 groups: 1 (N group) - patients with the normal intracranial pressure (≤12 mm Hg, n = 35) and 2 (E group) - patients with the elevated intracranial pressure (ICP > 12 mm Hg, n = 30). During the surgery we evaluated ICP, blood pressure, cerebral perfusion pressure (CPP). The parameters of recovery from anesthesia and the effectiveness of postoperative analgesia were also assessed. In N group ICP remained stable. In E group ICP decreased during anesthesia, the overall decline was 40% at the end of the operation (from 15 to 9 mm Hg (P intracranial pressure undergoing elective abdominal surgery under the condition of maintaining the arterial pressure. Its use is not associated with the increase in intracranial pressure during the anesthesia, but it needs an intraoperative monitoring of ICP in order to prevent CPP reduction.

    Full Text Available Abstract Background Surgery after (chemoradiation (RCTX/RTX is felt to be plagued with a high incidence of wound healing complications reported to be as high as 70%. The additional use of vascularized flaps may help to decrease this high rate of complications. Therefore, we examined within a retrospective single-institutional study the peri--and postoperative complications in patients who underwent surgery for salvage, palliation or functional rehabilitation after (chemoradiation with regional and free flaps. As a second study end point the Karnofsky performance status (KPS was determined preoperatively and 3 months postoperatively to assess the impact of such extensive procedures on the overall performance status of this heavily pretreated patient population. Findings 21 patients were treated between 2005 and 2010 in a single institution (17 male, 4 female for salvage (10/21, palliation (4/21, or functional rehabilitation (7/21. Overall 23 flaps were performed of which 8 were free flaps. Major recipient site complications were observed in only 4 pts. (19% (1 postoperative haemorrhage, 1 partial flap loss, 2 fistulas and major donor site complications in 1 pt (wound dehiscence. Also 2 minor donor site complications were observed. The overall complication rate was 33%. There was no free flap loss. Assessment of pre- and postoperative KPS revealed improvement in 13 out of 21 patients (62%. A decline of KPS was noted in only one patient. Conclusions We conclude that within this (chemoradiated patient population surgical interventions for salvage, palliation or improve function can be safely performed once vascularised grafts are used.

Prospective, pragmatic, multicentre, patient and assessor blinded, parallel group, randomised placebo controlled superiority trial. Multidisciplinary preadmission clinics at three tertiary public hospitals in Australia and New Zealand. 441 adults aged 18 years or older who were within six weeks of elective major open upper abdominal surgery were randomly assigned through concealed allocation to receive either an information booklet (n=219; control) or preoperative physiotherapy (n=222; intervention) and followed for 12 months. 432 completed the trial. Preoperatively, participants received an information booklet (control) or an additional 30 minute physiotherapy education and breathing exercise training session (intervention). Education focused on PPCs and their prevention through early ambulation and self directed breathing exercises to be initiated immediately on regaining consciousness after surgery. Postoperatively, all participants received standardised early ambulation, and no additional respiratory physiotherapy was provided. The primary outcome was a PPC within 14 postoperative hospital days assessed daily using the Melbourne group score. Secondary outcomes were hospital acquired pneumonia, length of hospital stay, utilisation of intensive care unit services, and hospital costs. Patient reported health related quality of life, physical function, and post-discharge complications were measured at six weeks, and all cause mortality was measured to 12 months. The incidence of PPCs within 14 postoperative hospital days, including hospital acquired pneumonia, was halved (adjusted hazard ratio 0.48, 95% confidence interval 0.30 to 0.75, P=0.001) in the intervention group compared with the control group, with an absolute risk reduction of 15% (95% confidence interval 7% to 22%) and a number needed to treat of 7

    Preoperative risk stratification is a critical element in assessing the risks and benefits of surgery. Prior work has demonstrated that intra-abdominal general surgery patients can be classified based on their comorbidities and risk factors using latent class analysis (LCA), a model-based clustering technique designed to find groups of patients that are similar with respect to characteristics entered into the model. Moreover, the latent risk classes were predictive of 30-day mortality. We evaluated the use of latent risk classes to predict the risk of major postoperative complications. An observational, retrospective cohort of patients undergoing intra-abdominal general surgery in the 2005 to 2010 American College of Surgeons National Surgical Quality Improvement Program was obtained. Known preoperative comorbidity and risk factor data were entered into LCA models to identify the latent risk classes. Complications were defined as: acute kidney injury, acute respiratory failure, cardiac arrest, deep vein thrombosis, myocardial infarction, organ space infection, pneumonia, postoperative bleeding, pulmonary embolism, sepsis/septic shock, stroke, unplanned reintubation, and/or wound dehiscence. Relative risk regression determined the associations between the latent classes and the 30-day complication risks, with adjustments for the surgical procedure. The area under the curve (AUC) of the receiver operator characteristic curve assessed model performance. LCA fit a 9-class model on 466,177 observations. The composite complication risk was 18.4% but varied from 7.7% in the lowest risk class to 56.7% in the highest risk class. After adjusting for procedure, the latent risk classes were significantly associated with complications, with risk ratios (95% confidence intervals) (compared to the class with the average risk) varying from 0.56 (0.54-0.58) in the lowest risk class to 2.15 (2.11-2.20) in the highest risk class, a 4-fold difference.

    Full Text Available Abstract Background Surgical site infections are common, so effective antibiotic concentrations at the sites of infection are required. Surgery can lead to physiological changes influencing the pharmacokinetics of antibiotics. The aim of the study is to evaluate contemporary peri-operative prophylactic dosing of cefazolin by determining plasma and subcutaneous interstitial fluid concentrations in patients undergoing elective of semi-elective abdominal aortic aneurysm (AAA open repair surgery. Methods/Design This is an observational pharmacokinetic study of patients undergoing AAA open repair surgery at the Royal Brisbane and Women's Hospital. All patients will be administered 2-g cefazolin by intravenous injection within 30-minutes of the procedure. Participants will have samples from blood and urine, collected at different intervals. Patients will also have a microdialysis catheter inserted into subcutaneous tissue to measure interstitial fluid penetration by cefazolin. Participants will be administered indocyanine green and sodium bromide as well as have cardiac output monitoring performed and tetrapolar bioimpedance to determine physiological changes occurring during surgery. Analysis of samples will be performed using validated liquid chromatography tandem mass-spectrometry. Pharmacokinetic analysis will be performed using non-linear mixed effects modeling to determine individual and population pharmacokinetic parameters and the effect of peri-operative physiological changes on cefazolin disposition. Discussion The study will describe cefazolin levels in plasma and the interstitial fluid of tissues during AAA open repair surgery. The effect of physiological changes to the patient mediated by surgery will also be determined. The results of this study will guide clinicians and pharmacists to effectively dose cefazolin in order to maximize the concentration of antibiotics in the tissues which are the most common site of surgical site infections.

    The first aim of the present study was to evaluate the pre- and postoperative B-type natriuretic peptide (BNP) levels in patients undergoing surgery for repair of an infrarenal abdominal aortic aneurysm (AAA) and analyze their power as a predictor of in-hospital cardiac events. The second aim was to evaluate the association among pre- and postoperative BNP levels, postoperative patient complications, and length of hospital stay. Prospective observational study. A university hospital. Forty-five patients undergoing elective surgery for an abdominal aortic aneurysm. The plasma BNP level was assessed just before surgery and then on postoperative day 1. Cardiac troponin I levels were measured postoperatively on arrival to the intensive care unit (time 0) and then 12, 48, and 72 hours later. The preoperative BNP concentration in patients who developed an acute myocardial infarction was 209 (IQR 84-346) pg/mL compared with 74 (IQR 28-142) pg/mL in those who did not. The difference between groups was statistically significant (p = 0.04). The Spearman correlation showed that postoperative BNP levels correlated significantly with preoperative BNP levels (r = 0.73, p = 0.0001), length of hospital stay (r = 0.35, p = 0.04), and troponin I concentration at 0 hour (r = 0.42, p = 0.02), 12 hours (r = 0.51, p = 0.0052), and 48 hours (r = 0.40, p = 0.033). In contrast, preoperative BNP levels correlated with troponin I at only 12 hours (r = 0.34, p = 0.02). Postoperative BNP levels were influenced significantly by transfusions (p = 0.035) and cross-clamping times (p = 0.038). The present results confirm the high negative predictive value of preoperative BNP levels; and postoperative BNP levels showed a better correlation with postoperative troponin levels, blood transfusion, and postoperative cardiac events.

    The aim of this study was to evaluate the effectiveness of implementing a physical therapy guideline for patients undergoing upper abdominal surgery (UAS) in reducing the incidence of atelectasis and length of hospital stay in the postoperative period. A "before and after" study design with historical control was used. The "before" period included consecutive patients who underwent UAS before guideline implementation (intervention). The "after" period included consecutive patients after guideline implementation. Patients in the pre-intervention period were submitted to a program of physical therapy in which the treatment planning was based on the individual experience of each professional. On the other hand, patients who were included in the post-intervention period underwent a standardized program of physical therapy with a focus on the use of additional strategies (EPAP, incentive spirometry and early mobilization). There was a significant increase in the use of incentive spirometry and positive expiratory airway pressure after guideline implementation. Moreover, it was observed that early ambulation occurred in all patients in the post-intervention period. No patient who adhered totally to the guideline in the post-intervention period developed atelectasis. Individuals in the post-intervention period presented a shorter length of hospital stay (9.2±4.1 days) compared to patients in the pre-intervention period (12.1±8.3 days) (p<0.05). The implementation of a physical therapy guideline for patients undergoing UAS resulted in reduced incidence of atelectasis and reduction in length of hospital stay in the postoperative period.

    Hospital-specific surgical site infection (SSI) performance following colon surgery and abdominal hysterectomies can impact hospitals' relative rankings around quality metrics used to determine financial penalties. Current SSI surveillance largely focuses on SSI detected at the operative hospital. Retrospective cohort study to assess the impact on hospitals' relative SSI performance rankings when SSI detected at non-operative hospitals are included. We utilized data from a California statewide hospital registry to assess for evidence of SSI following colon surgery or abdominal hysterectomies performed 3/1/2011-11/30/2013 using previously validated claims-based SSI surveillance methods. Risk-adjusted hospital-specific rankings based on SSI detected at operative hospitals versus any California hospital were generated. Among 60,059 colon surgeries at 285 hospitals and 64,918 abdominal hysterectomies at 270 hospitals, 5,921 (9.9%) colon surgeries and 1,481 (2.3%) abdominal hysterectomies received a diagnosis code for SSI within the 30 days following surgery. 7.2% of colon surgery and 13.4% of abdominal hysterectomy SSI would have been missed by operative hospital surveillance alone. The proportion of individual hospital's SSI detected during hospitalizations at other hospitals varied widely. Including non-operative hospital SSI resulted in improved relative ranking of 11 (3.9%) colon surgery and 13 (4.8%) hysterectomy hospitals so that they were no longer in the worst performing quartile, mainly among hospitals with relatively high surgical volumes. Standard SSI surveillance that mainly focuses on infections detected at the operative hospital causes varying degrees of SSI under-estimation, leading to inaccurate assignment or avoidance of financial penalties for approximately one in eleven to sixteen hospitals.

    Abdominal complications following cardiopulmonary bypass (CPB) procedures may have mortality rates as high as 25%. Advanced procedures such as ventricular assist devices, artificial hearts and cardiac transplantation are being increasingly employed, changing the complexity of interventions. This study was undertaken to examine the changing trends in complications and the impact of cardiac surgery on emergency general surgery (EGS) coverage. A retrospective review was conducted of all CPB procedures admitted to our ICU between Jan. 2007 and Mar. 2010. The procedures included coronary bypass (CABG), valve, combination (including adult congenital) and advanced heart failure (AHF) procedures. The records were reviewed to obtain demographics, need for EGS consult/procedure and outcomes. Mean age of the patients was 66 ± 8.5 years, 71% were male. There were 945 CPB procedures performed on 914 patients during this study period. Over 39 months, 23 EGS consults were obtained, resulting in 10 operations and one hospital death (10% operative mortality). CABG and valve procedures had minimal impact on EGS workload while complex cardiac and AHF procedures accounted for significantly more EGS consultations (p surgery, advanced technology has increased the volume of complex CPB procedures increasing the EGS workload. Emergency general surgeons working in institutions that perform advanced procedures should be aware of the potential for general surgical complications perioperatively and the resultant nuances that are associated with operative management in this patient population.

    Exact surgical planning is necessary for complex operations of pathological changes in anatomical structures of the pediatric abdomen. 3D visualization and computer-assisted operational planning based on CT data are being increasingly used for difficult operations in adults. To minimize radiation exposure and for better soft tissue contrast, sonography and MRI are the preferred diagnostic methods in pediatric patients. Because of manifold difficulties 3D visualization of these MRI data has not been realized so far, even though the field of embryonal malformations and tumors could benefit from this. A newly developed and modified raycasting-based powerful 3D volume rendering software (VG Studio Max 1.2) for the planning of pediatric abdominal surgery is presented. With the help of specifically developed algorithms, a useful surgical planning system is demonstrated. Thanks to the easy handling and high-quality visualization with enormous gain of information, the presented system is now an established part of routine surgical planning. (orig.) [de

Using flow cytometry, we examined the surface expression of TREM-1 and HLA-DR in peripheral blood monocytes from 11 septic patients, 7 elective gastrointestinal surgical patients, and 10 healthy volunteers. svTREM-1 levels were analyzed by RT-PCR. Basal expression of TREM-1 and HLA-DR in healthy volunteers was 35.91+/-14.75 MFI and 75.8+/-18.3%, respectively. In septic patients, TREM-1 expression was 59.9+/-23.9 MFI and HLA-DR expression was 44.39+/-20.25%, with a significant difference between healthy and septic groups (PSIRS, CARS, and sepsis.

    Full Text Available Blood transfusion is associated with well-known risks. We investigated the difference between a restrictive versus a liberal transfusion strategy on the immune response, as expressed by the production of inflammatory mediators, in patients subjected to major abdominal surgery procedures. Fifty-eight patients undergoing major abdominal surgery were randomized preoperatively to either a restrictive transfusion protocol or a liberal transfusion protocol (with transfusion if hemoglobin dropped below 7.7 g dL−1 or 9.9 g dL−1, respectively. In a subgroup of 20 patients randomly selected from the original allocation groups, blood was sampled for measurement of IL-6, IL-10, and TNFα. Postoperative levels of IL-10 were higher in the liberal transfusion group on the first postoperative day (49.82±29.07 vs. 15.83±13.22 pg mL−1, P<0.05. Peak postoperative IL-10 levels correlated with the units of blood transfused as well as the mean duration of storage and the storage time of the oldest unit transfused (r2=0.38, P=0.032, r2=0.52, P=0.007, and r2=0.68, P<0.001, respectively. IL-10 levels were elevated in patients with a more liberal red blood cell transfusion strategy. The strength of the association between anti-inflammatory IL-10 and transfusion variables indicates that IL-10 may be an important factor in transfusion-associated immunomodulation. This trial is registered under ClinicalTrials.gov Identifier: NCT02020525.

    Full Text Available Background: Postoperative pulmonary complications (PPC are of the major reasons for death. Prolonged mechanical ventilation (PMV and delayed extubation are leading to the incidence of more seriously complications. The effect of hyperinflation has not been investigated in control of these complications in patients who have been weaned from mechanical ventilation and are undergoing T-tube support. Aim: Investigation of MHI effect on oxygenation of patients following abdominal surgery and T-tube support. Method: This clinical trial was performed on 40 patients undergoing abdominal surgery and T-tube support hospitalized in intensive care units of hospitals in Mashhad, Iran, in 2015-2016. The participants were divided randomly into two experimental and control groups. In the experimental group, MHI technique was performed using Mapleson circuit for three twenty-minute periods. The control group received routine hospital care. The two groups were compared for PaO2, PaCO2 and SpO2 before intervention, 5 and 20 minutes after intervention. Data were analyzed using SPSS software. Results: The mean age was 66.7±8.3 and 67.5±9.0 years in experimental and control groups, respectively. In intergroup comparison using independent t-test, the mean PaCO2, PaO2 and SpO2 had no significant differences in the experimental group before the intervention. However, the means SpO2 and PaO2 at 5 and 20 minutes after intervention were significantly higher in the experimental group (p

    Early oral nutrition (EON) has been shown to improve recovery of gastrointestinal function, length of stay and mortality after abdominal surgery; however, early oral nutrition often fails during the first week after surgery. Here, a multi-modal early oral nutrition program is introduced to promote recovery of gastrointestinal function and tolerance of oral nutrition. Consecutive patients scheduled for abdominal surgery were randomized to the multimodal EON group or a group receiving conventional care. The primary endpoint was the time of first defecation. The secondary endpoints were outcomes and the cost-effectiveness ratio in treating infectious complications. The rate of infectious-free patients was regarded as the index of effectiveness. One hundred seven patients were randomly assigned to groups. Baseline characteristics were similar for both groups. In intention-to-treat analysis, the success rate of oral nutrition during the first week after surgery in the multimodal EON group was 44 (83.0%) versus 31 (57.4%) in the conventional care group (P = 0.004). Time to first defecation, time to flatus, recovery time of bowel sounds, and prolonged postoperative ileus were all less in the multimodal EON group (P oral nutrition group (P oral nutrition program was an effective way to improve tolerance of oral nutrition during the first week after surgery, decrease the length of stay and improve cost-effectiveness after abdominal surgery.

    The analgesia nociception index (ANI) is an online heart rate variability analysis proposed for assessment of the antinociception/nociception balance. In this observational study, we compared ANI with heart rate (HR) and systolic blood pressure (SBP) during various noxious stimuli in anaesthetized patients. 15 adult patients undergoing laparoscopic appendectomy or cholecystectomy were studied. Patients received target controlled infusions of propofol (adjusted to maintain the Bispectral index in the range [40-60]) and remifentanil (with target increase in case of haemodynamic reactivity [increase in HR and/or SBP >20% of baseline]), and cisatracurium. Medical staff was blind to the ANI monitor. ANI and haemodynamic data were recorded at predefined times before and during surgery, including tetanic stimulation of the ulnar nerve before start of surgery. Anaesthesia induction decreased HR and SBP, while high ANI values (88 [17]) were recorded, indicating parasympathetic predominance. In 10 out of 11 patients, tetanic stimulation led to a transient (surgery, ANI decreased to 60 (39) and decreased further to 50 (15) after the pneumoperitoneum was inflated, while there was no significant change in HR or SBP. When haemodynamic reactivity occurred, ANI had further decreased to 40 (15). After completion of surgery, ANI returned to 90 (34). ANI seems more sensitive than HR and SBP to moderate nociceptive stimuli in propofol-anaesthetized patients. Whether ANI monitoring may allow preventing haemodynamic reactivity to noxious stimuli remains to be demonstrated.

    2012-08-01

    Somatoform disorders (SD) or medically unexplained physical symptoms (MUPS) are a group of disorders that represent a group of symptoms that cannot be explained by an organic or physical pathology. These disorders are widely prevalent, and, if unrecognised, SD may lead medical professionals to embark on tests or procedures which may inflict unnecessary iatrogenic complications. Despite the high prevalence, they are only poorly included in medical training curricula, at both undergraduate and postgraduate levels. In this article, we review the literature and present two cases. The first one presented with a recurrent acute abdomen had an unnecessary CT abdomen. The second case had laparoscopy for acute right-sided abdominal pain which turned out to be normal, and was readmitted again after a short period with acute urine retention which resolved spontaneously following discussion with the patient and family. Both cases were referred for psychiatric assessment and their family doctors were informed.

    To prospectively evaluate predictive factors of hospital readmission rates in patients undergoing abdominal surgical procedures. Recommendations from MedPAC that the Centers for Medicare and Medicaid Services (CMS) report upon and determine payments based in part on readmission rates have led to an attendant interest by payers, hospital administrators and far-sighted physicians. Analysis of 266 prospective treated patients undergoing major abdominal surgical procedures from September 2009 to September 2010. All patients were prospectively evaluated for underlying comorbidities, number of preop meds, surgical procedure, incision type, complications, presence or absence of primary and/or secondary caregiver, their education level, discharge number of medications, and discharge location. Univariate and multivariate analyses were performed. Two hundred twenty-six patients were reviewed with 48 (18%) gastric-esophageal, 39(14%) gastrointestinal, 88 (34%) liver, 58 (22%) pancreas, and 33 (12%) other. Seventy-eight (30%) were readmitted for various diagnoses the most common being dehydration (26%). Certain preoperative and intraoperative factors were not found to be significant for readmission being, comorbidities, diagnosis, number of preoperative medications, patient education level, type of operation, blood loss, and complications. Significant predictive factors for readmission were age (≥69 years), number of discharged (DC) meds (≥9 medications), ≤50% oral intake (52% vs. 23%), and DC home with a home health agency (62% vs. 11%) Readmission rates for surgeons WILL become a quality indicator of performance. Quality parameters among Home Health agencies are nonexistent, but will reflect on surgeon’s performance. Greater awareness regarding predictors of readmission rates is necessary to demonstrate improved surgical quality.

    Directory of Open Access Journals (Sweden)

    P Kashefi

    2005-03-01

    Full Text Available Background: Perioperative pain is prevalent and poorly treated. Apart from that it makes the recovery from surgery unpleasent, pain often remains as a residual side effect of surgery, even though the tissue healing is complete. An essential observation is that tissue injury and the resulting nociceptor barrage initiates a cascade of events that can indelibly alter pain perception. Preemptive analgesia is the concept of initiating analgesic therapy before the onset of the noxious stimulus so as to prevent the nociceptor barrage and its consequences. However, anticipated clinical potency of preemptive analgesia, though has firmly grounded in the neurobiology of pain, has not been yet realized. As data accumulates, it has become clear that clinical studies emulating those from the laboratory and designed around a relatively narrow definition of preemptive analgesia have been largely unsupportive of its use. Nevertheless, preemptive analgesic interventions that recognize the intensity, duration, and somatotopic extent of major surgery can help reduce perioperative pain and its longer-term sequelae. surgeons spend a lot of time treating the pain of lower abdominal surgery. Methods: A total number of 48 consecutive patients who were going to undergo elective lower abdominal surgery. Were randomly assigned in two groups of 24 each. In one group the patients received an injection of 0.5 % bupivacaine in the planned skin for incision just before lower abdominal surgery, and in the other group, they received an equal amount of 0.5% bupivacaine after the surgery had been done. Pain was objectified by a numerical visual pain score, in the 24 hours following the lower abdominal surgery. Results: There were no differences in postoperative pain scores on the visual analog scale (VAS: In groups 1and 2, VAS at hour 4 were 6.37±1.13 versus 6.29±1.19; At hour 8 were 5.54 ± 1.17 versus 5.37±1.09; and at hour 12 were 4.5 ± 1.31 versus 4.45 ± 1

    This Data-in-Brief article contains a detailed method for the conduct of this survey and additional original data. In this survey, we also provided vascular surgery colleagues with contemporary epidemiologic and surgical outcome data. This was followed by a hypothetical scenario whereby a patient had just been diagnosed with a small (40 mm AAA and a novel biomarker predicted it to be fast growing in the coming years. We assessed the vascular professionals' perception of the patient's preference for management in this scenario, and their willingness to refer patients for a surgical trial that investigates the outcome of early versus late surgery in this setting. The survey then asked the vascular professionals to assume the role of the patient, and provided their own preferences in such a scenario.

    Full Text Available The aim of the study was to discuss the possibility and appropriateness of simultaneous operations in patients with metabolic syndrome (MS and obesity (O. Material and methods. The analysis of 50 simultaneous operations in patients with MS and O was performed. Gender, age, medical history and clinical-laboratory features were explored. Duration of operations, the number of complications, length of hospital stay were analyzed. Results and discussion. Body mass index ranged from 33 kg/m2 to 51 kg/m2. Skin and fat flaps weight ranged from 3 to 12 kg. Weight loss of patients in one week after surgery ranged from 5 to 14 kg. There were no complications in the early and late postoperative period. Analysis of carbohydrate metabolism showed no significant differences in pre- and post-operative period. Nevertheless simultaneous abdominoplasty as corrective surgery reduces weight, improves the self-perception of body image, physical and mental components of quality of life. Conclusion. The introduction of simultaneous operations will contribute: - for state: to increase and maintain the reproductive potential of the nation, to save the hospital beds, to save finances, to reduce the incidence of metabolic forms of cancer pathology; - for the patient: performing one operation instead of two ones, allowing to go through preoperative stress, anesthesia, postoperative period and the rehabilitation period once; during one operation to solve two-three issues; during surgical treatment of main disease to prevent oncological, cardio-vascular disease, diabetes, etc. Of course, the widespread adoption of the program of simultaneous gynecology, surgery requires the dissemination of knowledge and techniques refinement. simultaneous surgery; metabolic syndrome; obesity

    Acute pancreatitis clinically manifests various degrees of severity. In the present study, we performed a retrospective study on 39 cases of acute pancreatitis and examined the indications for surgery and infection as an aggravating factor in acute pancreatitis on the basis of CT in the early stage (about 48 hours after onset). CT in the early stage of acute pancreatitis permits objective determination of the extent of lesion enlargement. The cases could be classified into three grades: severe (CT score ≥ 6; surgical therapy), moderate (CT score = 5, 4; medical therapy possible), and mild (CT score ≤ 3; medical therapy) as determined by CT. Emergency surgery was performed in seven of 10 patients in whom pancreatitis was judged to be severe on the basis of CT and clinical findings. Of the seven, four had infection in the early stage (within 48 hours after onset). Three of the four had MOF complications and died. Two of the three patients without infection were relieved. The extent of inflammatory lesions of severe pancreatitis was severe by CT, and the CT scores were especially high in cases with infection. Infection in the early stage of acute pancreatitis was thus thought to be an serious aggravating factor. It was concluded, therefore, that, in the early stage, CT was very useful as a helpful guide to early judgement and an indicator for emergency surgery. (author)

    Effective analgesia after midline laparotomy surgery is essential for enhanced recovery programs. We compared three types of continuous abdominal wall block for analgesia after midline laparotomy for gynaecological oncology surgery. We conducted a single-centre, double-blind randomised controlled trial. Ninety-four patients were randomised into three groups to receive two days of programmed intermittent boluses of ropivacaine (18 ml 0.5% ropivacaine every four hours) via either a transversus abdominis plane (TAP) catheter, posterior rectus sheath (PRS) catheter, or a subcutaneous (SC) catheter. All groups received patient-controlled analgesia with morphine, and regular paracetamol and non-steroidal anti-inflammatory medication. Measured outcomes included analgesic and antiemetic usage and visual analog scores for pain, nausea, vomiting, and satisfaction. Eighty-eight patients were analysed (29 SC, 29 PRS and 30 TAP). No differences in the primary outcome were found (median milligrams morphine usage on day two SC 28, PRS 25, TAP 21, P =0.371). There were differences in secondary outcomes. Compared with the SC group, the TAP group required less morphine in recovery (0 mg versus 6 mg, P =0.01) and reported less severe pain on day one (visual analog scores 36.3 mm versus SC 55 mm, P =0.04). The TAP group used fewer doses of tropisetron on day one compared with the PRS group (8 versus 21, P =0.016). Programmed intermittent boluses of ropivacaine delivered via PRS, TAP and SC catheters can be provided safely to patients undergoing midline laparotomy surgery. Initially TAP catheters appear superior, reducing early opioid and antiemetic requirements and severe pain, but these advantages are lost by day two.

    The surgical site infection (SSI) is a common complication of abdominal operation. It relates to increased hospital stay, increased healthcare cost, and decreased patient's quality of life. Obesity, usually defined by BMI, is known as one of the risks of SSI. However, the thickness of subcutaneous layers of abdominal wall might be an important local factor affecting the rate of SSI after the abdominal operations. The objective of this study is to assess the importance of the abdominal wall thickness on incisional SSI rate. The subjects of the present study were patients who had undergone major abdominal operations at Thammasat University Hospital between June 2013 and May 2014, and had been investigated with CT scans before their operations. The demographic data and clinical information of these patients were recorded. The thickness ofsubcutaneous fatty tissue from skin down to the most superficial layer of abdominal wall muscle at the surgical site was measured on CT images. The wound infectious complication was reviewed and categorized as superficial and deep incisional SSIfollowing the definition from Centersfor Disease Control and Prevention (CDC) guidelines. The significance ofeach potentialfactors on SSI rates was determined separately with student t-test for quantitative data and χ2-test for categorical data. Then all factors, which had p operative CTscans. Post-operative SSI was 25.2% (35/139), superficial and deep types in 27 and 8 patients, respectively. The comparison of abdominal wall thickness between patients with and without infection was significantly different (20.0 ± 8.4 mm and 16.0 ± 7.2 mm, respectively). When the thickness at 20 mm was used as the cut-off value, 43 of 139 patients had abdominal wall thickness ≥ 20 mm. The incidence of SSI of the thickness ±20 mm group was 37.2% (16/43) and of the less thickness group was 19.8% (19/96), with p operation. However, only abdominal wall thickness and wound classification were still significant

    We report three cases of abdominal wall necrotizing fasciitis that occurred as a result of leakage from displaced percutaneous endoscopic gastrostomy tubes. This is the first report of such a series. Patients underwent extensive operative excisions of their abdominal walls down to their posterior fascia. All patients tolerated their initial surgery, however, two patients ultimately expired from respiratory complications. The surviving patient underwent multiple repeat debridements and reconstructive abdominal wall surgery. We review the epidemiology of patients at risk for this complication and discuss its presentation, as well as the appropriate workup and management. We also address the issues of closure of large abdominal wall defects and future alimentation in this patient group. Finally, abdominal wall necrotizing faciitis from gastrostomy tube leakage is a devastating complication, and the development of preventative strategies for patients at risk is of paramount importance.

    Infectious complications occur frequently after major abdominal surgery and have a major influence on patient outcome and hospital costs. A marker that can rule out postoperative infectious complications (PICs) could aid patient selection for safe and early hospital discharge. C-reactive protein (CRP) is a widely available, fast, and cheap marker that might be of value in detecting PIC. Present meta-analysis evaluates the diagnostic value of CRP to rule out PIC following major abdominal surgery, aiding patient selection for early discharge. A systematic literature search of Medline, PubMed, and Cochrane was performed identifying all prospective studies evaluating the diagnostic value of CRP after abdominal surgery. Meta-analysis was performed according to the PRISMA statement. Twenty-two studies were included for qualitative analysis of which 16 studies were eligible for meta-analysis, representing 2215 patients. Most studies analyzed the value of CRP in colorectal surgery (eight studies). The pooled negative predictive value (NPV) improved each day after surgery up to 90% at postoperative day (POD) 3 for a pooled CRP cutoff of 159 mg/L (range 92-200). Maximum predictive values for PICs were reached on POD 5 for a pooled CRP cutoff of 114 mg/L (range 48-150): a pooled sensitivity of 86% (95% confidence interval (CI) 79-91%), specificity of 86% (95% CI 75-92%), and a positive predictive value of 64% (95% CI 49-77%). The pooled sensitivity and specificity were significantly higher on POD 5 than on other PODs (p < 0.001). Infectious complications after major abdominal surgery are very unlikely in patients with a CRP below 159 mg/L on POD 3. This can aid patient selection for safe and early hospital discharge and prevent overuse of imaging.

    Purpose: To assess the feasibility and toxicity of consolidative intensity-modulated whole abdominal radiotherapy (WAR) after surgery and chemotherapy in high-risk patients with advanced ovarian cancer. Methods and Materials: Ten patients with optimally debulked ovarian cancer International Federation of Gynecology and Obstetrics Stage IIIc were treated in a Phase I study with intensity-modulated WAR up to a total dose of 30 Gy in 1.5-Gy fractions as consolidation therapy after adjuvant carboplatin/taxane chemotherapy. Treatment was delivered using intensity-modulated radiotherapy in a step-and-shoot technique (n = 3) or a helical tomotherapy technique (n = 7). The planning target volume included the entire peritoneal cavity and the pelvic and para-aortal node regions. Organs at risk were kidneys, liver, heart, vertebral bodies, and pelvic bones. Results: Intensity-modulated WAR resulted in an excellent coverage of the planning target volume and an effective sparing of the organs at risk. The treatment was well tolerated, and no severe Grade 4 acute side effects occurred. Common Toxicity Criteria Grade III toxicities were as follows: diarrhea (n = 1), thrombocytopenia (n = 1), and leukopenia (n = 3). Radiotherapy could be completed by all the patients without any toxicity-related interruption. Median follow-up was 23 months, and 4 patients had tumor recurrence (intraperitoneal progression, n = 3; hepatic metastasis, n = 1). Small bowel obstruction caused by adhesions occurred in 3 patients. Conclusions: The results of this Phase I study showed for the first time, to our knowledge, the clinical feasibility of intensity-modulated whole abdominal radiotherapy, which could offer a new therapeutic option for consolidation treatment of advanced ovarian carcinoma after adjuvant chemotherapy in selected subgroups of patients. We initiated a Phase II study to further evaluate the toxicity of this intensive multimodal treatment.

    The effects of individualised perioperative lung-protective ventilation (based on the open-lung approach [OLA]) on postoperative complications is unknown. We aimed to investigate the effects of intraoperative and postoperative ventilatory management in patients scheduled for abdominal surgery, compared with standard protective ventilation. We did this prospective, multicentre, randomised controlled trial in 21 teaching hospitals in Spain. We enrolled patients who were aged 18 years or older, were scheduled to have abdominal surgery with an expected time of longer than 2 h, had intermediate-to-high-risk of developing postoperative pulmonary complications, and who had a body-mass index less than 35 kg/m 2 . Patients were randomly assigned (1:1:1:1) online to receive one of four lung-protective ventilation strategies using low tidal volume plus positive end-expiratory pressure (PEEP): open-lung approach (OLA)-iCPAP (individualised intraoperative ventilation [individualised PEEP after a lung recruitment manoeuvre] plus individualised postoperative continuous positive airway pressure [CPAP]), OLA-CPAP (intraoperative individualised ventilation plus postoperative CPAP), STD-CPAP (standard intraoperative ventilation plus postoperative CPAP), or STD-O 2 (standard intraoperative ventilation plus standard postoperative oxygen therapy). Patients were masked to treatment allocation. Investigators were not masked in the operating and postoperative rooms; after 24 h, data were given to a second investigator who was masked to allocations. The primary outcome was a composite of pulmonary and systemic complications during the first 7 postoperative days. We did the primary analysis using the modified intention-to-treat population. This trial is registered with ClinicalTrials.gov, number NCT02158923. Between Jan 2, 2015, and May 18, 2016, we enrolled 1012 eligible patients. Data were available for 967 patients, whom we included in the final analysis. Risk of pulmonary and systemic

    Intraoperative mechanical ventilation may yield lung injury. To date, there is no consensus regarding the best ventilator strategy for abdominal surgery. We aimed to investigate the impact of the mechanical ventilation strategies used in 2 recent trials (Intraoperative Protective Ventilation [IMPROVE] trial and Protective Ventilation using High versus Low PEEP [PROVHILO] trial) on driving pressure (ΔPRS), mechanical power, and lung damage in a model of open abdominal surgery. Thirty-five Wistar rats were used, of which 28 were anesthetized, and a laparotomy was performed with standardized bowel manipulation. Postoperatively, animals (n = 7/group) were randomly assigned to 4 hours of ventilation with: (1) tidal volume (VT) = 7 mL/kg and positive end-expiratory pressure (PEEP) = 1 cm H2O without recruitment maneuvers (RMs) (low VT/low PEEP/RM-), mimicking the low-VT/low-PEEP strategy of PROVHILO; (2) VT = 7 mL/kg and PEEP = 3 cm H2O with RMs before laparotomy and hourly thereafter (low VT/moderate PEEP/4 RM+), mimicking the protective ventilation strategy of IMPROVE; (3) VT = 7 mL/kg and PEEP = 6 cm H2O with RMs only before laparotomy (low VT/high PEEP/1 RM+), mimicking the strategy used after intubation and before extubation in PROVHILO; or (4) VT = 14 mL/kg and PEEP = 1 cm H2O without RMs (high VT/low PEEP/RM-), mimicking conventional ventilation used in IMPROVE. Seven rats were not tracheotomized, operated, or mechanically ventilated, and constituted the healthy nonoperated and nonventilated controls. Low VT/moderate PEEP/4 RM+ and low VT/high PEEP/1 RM+, compared to low VT/low PEEP/RM- and high VT/low PEEP/RM-, resulted in lower ΔPRS (7.1 ± 0.8 and 10.2 ± 2.1 cm H2O vs 13.9 ± 0.9 and 16.9 ± 0.8 cm H2O, respectively; Pmechanical power (63 ± 7 and 79 ± 20 J/min vs 110 ± 10 and 120 ± 20 J/min, respectively; P = .007). Low VT/high PEEP/1 RM+ was associated with less alveolar collapse than low VT/low PEEP/RM- (P = .03). E-cadherin expression was higher in

    Vacuum-assisted fascial closure (VAFC-KCI(®)) of an open abdomen is one of the latest methods. A prospective observational study was performed with medical records of nine patients who had been treated by abdominal VAFC-KCI(®) from March 2006 to October 2007 in the Department of Surgical Sciences, University of Insubria. The mean Acute Physiology and Chronic Health Evaluation II and Sequential Organ Failure Assessment scores were 22.62 and 10.62, respectively. All patients had abdominal compartment syndrome and a sepsis source that was difficult to control. All patients survived. The mean duration of open abdomen was 22.7 days (range, 3-50 days). Primary fascial closure was possible in six patients (66%), with a closure rate of 100% when early control of the infectious source was possible (Group A) but only 40% in patients with difficult and delayed control of infection (Group B). The mean durations of open abdomen in the two groups were statistically different: 8.5 days for Group A vs. 34.2 days for Group B (p high fascial closure rate. The complexity of the management of abdominal source control has a role in the success of primary fascial closure. The VAFC-KCI(®) system seems to contribute positively in fascia-to-fascia abdominal closure in cases of severe abdominal infection, in particular when early surgical source control is obtained.

    SI is a significant medical problem. DFA-02 is an investigational bioresorbable modified release gel consisting of both gentamicin (16.8 mg/mL) and vancomycin (18.8 mg/mL). A Phase 2a study, where the drug was applied during surgical incision closure, suggested safety and tolerability but was not designed to assess its efficacy. In a Phase 2b randomized, blinded trial patients undergoing abdominal, primarily colorectal, surgery were randomized (4:1:1) to one of three study arms: DFA-02, matching placebo gel, or standard of care (SOC) involving irrigation of the wound with normal saline. The DFA-02 and placebo gel groups received up to 20 mL of study drug inserted above the fascia during wound closure, and were treated in a double-blind manner; the SOC group was treated in a single-blind manner. The primary endpoint was SSI (adjudicated centrally by a blinded committee) through postoperative day 30. Overall, 445 subjects (intention-to-treat) were randomized at 35 centers with 425 subjects completing the study and being evaluable. There were 67 SSIs (15.8%): 64.2% superficial, 7.5% deep, and 28.4% organ space. The incidence of SSI was not statistically significantly different between the DFA-02 and the placebo gel/SOC arms combined, 42/287 = 14.6% vs 25/138 = 18.1% (p = 0.36), respectively. Rehospitalization within 30 days was also similar between study groups (DFA-02 28.6%, placebo gel 21.4%, SOC 27.3%). In this multicenter, blinded, randomized trial with central adjudication, the gentamicin/vancomycin gel was not associated with a significant reduction in SSI. Patients undergoing abdominal surgery were randomized to one of three study arms: DFA-02 gel consisting of both gentamicin and vancomycin, matching placebo gel, or standard of care (SOC). Of 425 patients completing the study at 35 sites the gentamicin/vancomycin gel was not associated with a significant reduction in SSI. Copyright © 2016 Elsevier Inc. All rights reserved.

    Elderly patients are more prone than younger patients to develop cerebral desaturation because of the reduced physiologic reserve that accompanies aging. To evaluate whether monitoring cerebral oxygen saturation (rSO(2)) minimizes intraoperative cerebral desaturation, we prospectively monitored rSO(2) in 122 elderly patients undergoing major abdominal surgery with general anesthesia. Patients were randomly allocated to an intervention group (the monitor was visible and rSO(2) was maintained at > or =75% of preinduction values; n = 56) or a control group (the monitor was blinded and anesthesia was managed routinely; n = 66). Cerebral desaturation (rSO(2) reduction <75% of baseline) was observed in 11 patients of the treatment group (20%) and 15 patients of the control group (23%) (P = 0.82). Mean (95% confidence intervals) values of mean rSO(2) were higher (66% [64%-68%]) and the area under the curve below 75% of baseline (AUCrSO2(2)< 75% of baseline) was lower (0.4 min% [0.1-0.8 min%]) in patients of the treatment group than in patients of the control group (61% [59%-63%] and 80 min% [2-144 min%], respectively; P = 0.002 and P = 0.017). When considering only patients developing intraoperative cerebral desaturation, a lower Mini Mental State Elimination (MMSE) score was observed at the seventh postoperative day in the control group (26 [25-30]) than in the treatment group (28 [26-30]) (P = 0.02), with a significant correlation between the AUCrSO(2) < 75% of baseline and postoperative decrease in MMSE score from preoperative values (r(2)= 0.25, P = 0.01). Patients of the control group with intraoperative cerebral desaturation also experienced a longer time to postanesthesia care unit (PACU) discharge (47 min [13-56 min]) and longer hospital stay (24 days [7-53] days) compared with patients of the treatment group (25 min [15-35 min] and 10 days [7-23 days], respectively; P = 0.01 and P = 0.007).

    To compare the efficacy of chlorhexidine-gluconate versus povidone iodine in preoperative skin preparation in the prevention of surgical site infections (SSIs) in clean-contaminated upper abdominal surgeries. This was a prospective randomized controlled trial conducted on patients undergoing clean-contaminated upper abdominal surgeries. A total of 351 patients 18-70 years old were randomized into two groups; chlorhexidine and povidone iodine skin preparation before surgery. The incidence of SSIs in the chlorhexidine group was 10.8 %, in comparison to 17.9 % in the povidone iodine group. The odds ratio was 0.6 in favor of chlorhexidine use, but the results were not statistically significant (P = 0.06). In the first postoperative week, SSIs developed in 7 % of patients in the chlorhexidine group and 14.1 % in the povidone iodine group (P = 0.03), and in the second postoperative week, SSIs were present in 4.1 % of the patients in the chlorhexidine group and 4.4 % in the povidone iodine group, which was not statistically significant (P = 0.88). The incidence of SSIs after clean-contaminated upper abdominal surgeries was lower with the use of chlorhexidine skin preparation than with povidone iodine preparation, although the results were not statistically significant. However, the odds ratio between the two groups favored the use of chlorhexidine over povidone iodine for preventing SSIs.

    This study was undertaken to evaluate the safety, feasibility, and the long-term effectiveness of laparoscopy in endometrial cancer patients aged 80 years or older. Data of consecutive patients aged 80 years and older undergoing laparoscopic, open abdominal, and vaginal approaches were compared. Postoperative complications were graded per the Accordion Severity Classification. Survival outcomes within the first 5 years were analyzed using the Kaplan-Meier method. Among 726 patients, 63 (9%) were aged 80 years and older. Laparoscopic, open abdominal, and vaginal surgery were performed in 22 (35%), 25 (40%), and 16 (25%) cases, respectively. All laparoscopic procedures were completed laparoscopically, whereas a conversion from vaginal to open procedure occurred (0% vs 6%; P = 0.42). Patients undergoing laparoscopy experienced similar operative time (P > 0.05), lower blood loss (P vaginal surgery. No intraoperative complications were recorded. Laparoscopy is related to a lower rate of postoperative complications (P = 0.09) and Accordion grade greater than or equal to 2 complications (P = 0.05) in comparison to open abdominal and vaginal surgery. The route of surgical approaches did not influence the 5-year disease-free (P = 0.97, log-rank test) and overall (P = 0.94, log-rank test) survivals. Laparoscopy seems to represent a safe and effective treatment of endometrial cancer in women aged 80 years or older. Our data suggest that in elderly women, laparoscopic surgery improves perioperative outcomes compared with open and vaginal approaches without compromising long-term survival.

The global risk score of abdominal wound dehiscence group (mean: 4.97; IC 95%: 4.15-5.79) was better than the global risk score of No abdominal wound dehiscence group (mean: 3.41; IC 95%: 3.20-3.62). This difference is statistically significant (P<.001). The preoperative risk score of abdominal wound dehiscence group (mean: 3.27; IC 95%: 2.69-3.84) was better than the preoperative risk score of No abdominal wound dehiscence group (mean: 2.77; IC 95%: 2.64-2.89), also a statistically significant difference (P<.05). The global risk score (area under the ROC curve: 0.79) has better accuracy than the preoperative risk score (area under the ROC curve: 0.64). The risk model developed by van Ramshorst et al. to predict the abdominal wound dehiscence's risk in the preoperative phase has a limited usefulness. Additional refinements in the preoperative risk score are needed to improve its accuracy. Copyright © 2012 AEC. Published by Elsevier Espana. All rights reserved.

    Post-operative pulmonary complications are a significant problem following open upper abdominal surgery. Preliminary evidence suggests that a single pre-operative physiotherapy education and preparatory lung expansion training session alone may prevent respiratory complications more effectively than supervised post-operative breathing and coughing exercises. However, the evidence is inconclusive due to methodological limitations. No well-designed, adequately powered, randomised controlled trial has investigated the effect of pre-operative education and training on post-operative respiratory complications, hospital length of stay, and health-related quality of life following upper abdominal surgery. The Lung Infection Prevention Post Surgery - Major Abdominal- with Pre-Operative Physiotherapy (LIPPSMAck POP) trial is a pragmatic, investigator-initiated, bi-national, multi-centre, patient- and assessor-blinded, parallel group, randomised controlled trial, powered for superiority. Four hundred and forty-one patients scheduled for elective open upper abdominal surgery at two Australian and one New Zealand hospital will be randomised using concealed allocation to receive either i) an information booklet or ii) an information booklet, plus one additional pre-operative physiotherapy education and training session. The primary outcome is respiratory complication incidence using standardised diagnostic criteria. Secondary outcomes include hospital length of stay and costs, pneumonia diagnosis, intensive care unit readmission and length of stay, days/h to mobilise >1 min and >10 min, and, at 6 weeks post-surgery, patient reported complications, health-related quality of life, and physical capacity. The LIPPSMAck POP trial is a multi-centre randomised controlled trial powered and designed to investigate whether a single pre-operative physiotherapy session prevents post-operative respiratory complications. This trial standardises post-operative assisted ambulation and

    Full Text Available Abstract Background To summarize the diagnostic and therapeutic experiences on the patients who suffered abdominal complications after cardiovascular surgery with cardiopulmonary bypass(CPB. Methods A total of 2349 consecutive patients submitted to cardiovascular surgery with CPB in our hospital from Jan 2004 to Dec 2010 were involved. The clinical data of any abdominal complication, including its incidence, characters, relative risks, diagnostic measures, medical or surgical management and mortality, was retrospectively analyzed. Results Of all the patients, 33(1.4% developed abdominal complications postoperatively, including 11(33.3% cases of paralytic ileus, 9(27.3% of gastrointestinal haemorrhage, 2(6.1% of gastroduodenal ulcer perforation, 2(6.1% of acute calculus cholecystitis, 3(9.1% of acute acalculus cholecystitis, 4(12.1% of hepatic dysfunction and 2(6.1% of ischemia bowel diseases. Of the 33 patients, 26 (78.8% accepted medical treatment and 7 (21.2% underwent subsequent surgical intervention. There were 5(15.2% deaths in this series, which was significantly higher than the overall mortality (2.7%. Positive history of peptic ulcer, advanced ages, bad heart function, preoperative IABP support, prolonged CPB time, low cardiac output and prolonged mechanical ventilation are the risk factors of abdominal complications. Conclusions Abdominal complications after cardiovascular surgery with CPB have a low incidence but a higher mortality. Early detection and prompt appropriate intervention are essential for the outcome of the patients.

    We studied whether reported physical activity and measurements of fitness (hand, leg and inspiration) were associated with postoperative in-hospital mortality, length of stay and discharge destination in 169 patients after major oncological abdominal surgery. In multivariate analysis, adequate activity level (OR 5.5, 95% CI 1.4-21.9) and inspiratory muscle endurance (OR 5.2, 95% CI 1.4-19.1) were independently associated with short-term mortality, whereas conventional factors, such as age and heart disease, were not. Adequate activity level (OR 6.7, 95% CI 1.4-3.0) was also independently associated with discharge destination. The factors that were independently associated with a shorter length of hospital stay were as follows: absence of chronic obstructive pulmonary disease (HR 0.6, 95% CI 0.3-1.1); adequate activity level (HR 0.6, 95% CI 0.4-0.8); and inspiratory muscle strength (HR 0.6, 95% CI 0.5-0.9). For all postoperative outcomes physical activity and fitness significantly improved the predictive value compared with known risk factors, such as age and comorbidities. We conclude that pre-operative questionnaires of physical activity and measurements of fitness contribute to the prediction of postoperative outcomes.

    The aims of this study were to reveal how using the antibiotics recommended by the 2010 Surgical Infection Society (SIS) and Infectious Disease Society of America (IDSA) guidelines can affect the therapeutic outcomes. We reviewed the cases of 53 patients with a postoperative intra-abdominal abscess without anastomotic leakage after gastrointestinal surgery who underwent image-guided percutaneous abscess drainage (PAD) and concomitant antibiotic therapy. The type of antibiotic initially administered was determined based on the surgeon's judgment. A persistent abscess was defined as one or more PAD procedures resulting in complete resolution after 21 or more days. The recommended antibiotics were defined according to 2010 SIS/IDSA guidelines. All 53 patients had complete resolution without the need for surgery. The results of a multivariable analysis revealed that a C-reactive protein level ≥12 mg/dL and non-recommended antibiotics were significant risk factors for a persistent abscess (P = 0.042 and 0.013, respectively). With regard to a fever lasting more than 48 h, there was a significant difference between the recommended (45.1%) and non-recommended (72.7 %) antibiotic groups (P = 0.046). Using the recommended antibiotics may shorten the time to defervescence and reduce the risk of a persistent abscess in patients undergoing PAD for a postoperative abscess after gastrointestinal surgery.

    Male, 74 FINAL DIAGNOSIS: Abdominal aortic aneurysm (AAA) Symptoms: Palpable abdominal mass Medication: - Clinical Procedure: Abdominal aortic aneurysm repair Specialty: Surgery. Rare disease. Coronary artery disease is common in elderly patients with abdominal aortic aneurysms. Here we report a case of the combination of surgical repair for abdominal aortic aneurysm and off-pump and minimally invasive coronary artery bypass surgery. A 74-year-old man who presented at our clinic with chest pain was diagnosed with an abdominal aortic aneurysm. His medical history included right coronary artery stenting. Physical examination revealed a pulsatile abdominal mass on the left side and palpable peripheral pulses. Computed tomography scans showed an infrarenal abdominal aneurysm with a 61-mm enlargement. Coronary angiography revealed 80% stenosis in the stent within the right coronary artery and 20% stenosis in the left main coronary artery. The patient underwent elective coronary artery bypass grafting and abdominal aortic aneurysm repair. Abdominal aortic aneurysm repair and transdiaphragmatic off-pump and minimal invasive coronary artery bypass grafting with right gastroepiploic artery were performed simultaneously in a single surgery. We report this case to emphasize the safety and effectiveness of transdiaphragmatic off-pump and minimally invasive coronary artery bypass surgery with abdominal aortic aneurysm repair. This combined approach shortens hospital stay and decreases cost.

    In surgery prophylaxis for infection is necessary, because patients are immunocompromised due to the underlying disease and the operation while at the same time being increasingly exposed to potentially pathogenic germs. Prophylaxis is based on the control of endogenous and exogenous microorganisms. For this purpose either systemic or locally active topical agents may be employed. Systemically active substances are applied with the aim to kill and eliminate invasive microorganisms in deep tissue levels, either by their own biological activity or by stimulating specific or unspecific host immune reactions. Local topical measures in contrast are to prevent the primary contact between microorganisms and host. The central pillar of systemic measures is the perioperative systemic antibiotic prophylaxis, immunonutrition is beginning to gain importance, and in the future possibly substances such as G-CSF, which directly stimulate the immune system, may be employed. Standard topical measures are sterilization and desinfection while decontamination of the digestive tract has until now not found a wide spread acceptance. For certain indications especially high risk surgical resections with anastomoses at the level of the oesophagus or the lower rectum it is possible to eliminate endogenous intestinal microorganisms effectively using topical decontamination in combination with systemic antibiotics and improve the surgical results, especially anastomotic healing.

    AIM: The technical performance of abdominal ultrasound in the investigation of acute abdominal pain has been thoroughly investigated but its therapeutic effects are less well understood. We aimed to determine the therapeutic effect of abdominal ultrasound in the investigation of acute abdominal pain. MATERIAL AND METHODS: A pre- and post-intervention observational study design was used to determine the diagnostic and therapeutic effects of abdominal ultrasound for acute abdominal pain. Referring clinicians completed a pre-ultrasound questionnaire that detailed their leading diagnosis, confidence in this and intended management in 100 consecutive adult patients. Following ultrasound a second questionnaire was completed. This again detailed the leading diagnosis, confidence in this and their intended management. Clinicians quantified the management contribution of ultrasound both for the individual case in question and in their clinical experience generally. RESULTS: The leading diagnosis was either confirmed or rejected in 72 patients and a new diagnosis provided where no prior differential diagnosis existed in 10. Diagnostic confidence increased significantly following ultrasound (mean score 6·5 pre-ultrasound vs 7·6 post-ultrasound, P < 0·001). Intended management changed following ultrasound in 22 patients; 15 intended laparotomies were halted and a further seven patients underwent surgery where this was not originally intended. Ultrasound was rated either 'very' or 'moderately' helpful in 87% of patients, with 99% of clinicians finding it either 'very' or 'moderately' helpful generally. CONCLUSION: Abdominal ultrasound has considerable diagnostic and therapeutic effect in the setting of acute abdominal pain. Dhillon, S. et al. (2002)

O objetivo foi comparar duas técnicas de incentivo respiratório na recuperação da dinâmica toracoabdominal em pacientes submetidos à cirurgia abdominal alta. O grupo de estudo experimental foi constituído por 16 pacientes internados na Clínica Cirúrgica do Hospital Universitário de Santa Maria distribuídos aleatoriamente em dois grupos: o grupo 1 foi constituído por dez pacientes que usaram o dispositivo Voldyne e o grupo 2, por seis pacientes submetidos ao padrão ventilatório com inspiração fracionada em três tempos. A expansibilidade toracoabdominal foi avaliada por cirtometria antes da cirurgia e no 1º, 3º¸ e 5º dias do pós-operatório (PO. Observou-se redução significativa dos valores de cirtometria no 1º PO que, gradualmente, foram sendo recuperados, não mais havendo diferença significativa no 5o PO em relação aos valores pré-operatórios em ambos os grupos. O grupo 1 obteve significativamente melhores índices de recuperação da mobilidade toracoabdominal do que o grupo 2. Também o tempo de recuperação do grupo 1 atingiu médias mais elevadas durante todo o período de PO investigado. Embora ambas as técnicas utilizadas fossem efetivas, o incentivo inspiratório por meio do Voldyne mostrou melhores resultados na recuperação da expansibilidade pulmonar após cirurgia abdominal alta.Upper abdominal surgery is associated to increased risk of pulmonary complications, which may be lessened by judicious use of therapeutic maneuvers aimed at lung expansion.

    Industry sponsorship has been identified as a factor correlating with positive research findings in several fields of medical science. To date, the influence of industry sponsorship in general and abdominal surgery has not been fully studied. This protocol describes the rationale and planned conduct of a systematic review to determine the association between industry sponsorship and positive outcome in randomised controlled trials in general and abdominal surgery. A literature search in the Cochrane Library, MEDLINE and EMBASE and additional hand searches in relevant citations will be conducted. In order to cover all relevant areas of general and abdominal surgery, a new literature search strategy called multi-PICO search strategy (MPSS) has been developed. No language restriction will be applied. The search will be limited to publications between January 1985 and July 2014. Information on funding source, outcome, study characteristics and methodological quality will be extracted.The association between industry sponsorship and positive outcome will be tested by a chi-squared test. A multivariate logistic regression analysis will be performed to control for possible confounders, such as number of study centres, multinational trials, methodological quality, journal impact factor and sample size. This study was designed to clarify whether industry-sponsored trials report more positive outcomes than non-industry trials. It will be the first study to evaluate this topic in general and abdominal surgery. The findings of this study will enable surgical societies, in particular, to give advice about cooperation with the industry and disclosure of funding source based on empirical evidence.

    The objective of this study was to evaluate the impact of perioperative glutamine-supplemented parenteral nutrition (GLN-PN) on clinical outcomes in patients undergoing abdominal surgery. MEDLINE, EMBASE, and the Cochrane Controlled Clinical Trials Register were searched to retrieve the eligible studies. Eligible studies were randomized controlled trials (RCTs) that compared the effect of GLN-PN and standard PN on clinical outcomes in patients undergoing abdominal surgery. Clinical outcomes of interest were postoperative mortality, length of hospital stay, morbidity of infectious complication, and cumulative nitrogen balance. Statistical analysis was conducted by RevMan 5.0 software from the Cochrane Collaboration. Sixteen RCTs with 773 patients were included in this meta-analysis. The results showed a significant decrease in the infectious complication rates of patients undergoing abdominal surgery receiving GLN-PN (risk ratio [RR], 0.48; 95% confidence interval [CI], 0.32 to 0.72; P = 0.0004). The overall effect indicated glutamine significantly reduced the length of hospital stay in the form of alanyl-glutamine (weighted mean difference [WMD], -3.17; 95% CI, -5.51 to -0.82; P = 0.008) and in the form of glycyl-glutamine (WMD, -3.40; 95% CI, -5.82 to -0.97; P = 0.006). A positive effect in improving postoperative cumulative nitrogen balance was observed between groups (WMD, 7.40; 95% CI, 3.16 to 11.63; P = 0.0006), but no mortality (RR, 1.52; 95% CI, 0.21 to 11.9; P = 0.68). Perioperative GLN-PN is effective and safe to shorten the length of hospital stay, reduce the morbidity of postoperative infectious complications, and improve nitrogen balance in patients undergoing abdominal surgery.

    Full Text Available Postoperative complications frequently follow major abdominal surgery and are associated with increased morbidity and mortality. Early diagnosis and treatment of complications is associated with improved patient outcome. In this study we assessed the value of a step-up diagnosis plan by C-reactive protein and CT-scan (computed tomography-scan imaging for detection of postoperative complications following major abdominal surgery. An observational cohort study was conducted of 399 consecutive patients undergoing major abdominal surgery between January 2009 and January 2011. Indication for operation, type of surgery, postoperative morbidity, complications according to the Clavien-Dindo classification and mortality were recorded. Clinical parameters were recorded until 14 days postoperatively or until discharge. Regular C-reactive protein (CPR measurements in peripheral blood and on indication -enhanced CT-scans were performed. Eighty-three out of 399 (20.6 % patients developed a major complication in the postoperative course after a median of seven days (IQR 4-9 days. One hundred and thirty two patients received additional examination consisting of enhanced CT-scan imaging, and treatment by surgical reintervention or intensive care observation. CRP levels were significantly higher in patients with postoperative complications. On the second postoperative day CRP levels were on average 197.4 mg/L in the uncomplicated group, 220.9 mg/L in patients with a minor complication and 280.1 mg/L in patients with major complications (p < 0,001. CT-scan imaging showed a sensitivity of 91.7 % and specificity of 100 % in diagnosis of major complications. Based on clinical deterioration and the increase of CRP, an additional enhanced CT-scan offered clear discrimination between patients with major abdominal complications and uncomplicated patients. Adequate treatment could then be accomplished.

    Full Text Available Abstract Background In patients undergoing open cardiothoracic and upper abdominal surgery, postoperative pulmonary complications remain an important cause of postoperative morbidity and mortality, impacting upon hospital length of stay and health care resources. Adequate preoperative respiratory muscle strength may help protect against the development of postoperative pulmonary complications and therefore preoperative inspiratory muscle training has been suggested to be of potential value in improving postoperative outcomes. Methods/Design A systematic search of electronic databases will be undertaken to identify randomized trials of preoperative inspiratory muscle training in patients undergoing elective open cardiothoracic and upper abdominal surgery. From these trials, we will extract available data for a list of predefined outcomes, including postoperative pulmonary complications, hospital length of stay and respiratory muscle strength. We will meta-analyze comparable results where possible, and report a summary of the available pool of evidence. Discussion This review will provide the most comprehensive answer available to the question of whether preoperative inspiratory muscle training is clinically useful in improving postoperative outcomes in patients undergoing cardiothoracic and upper abdominal surgery. It will help inform clinicians working in the surgical arena of the likely effectiveness of instituting preoperative inspiratory muscle training programs to improve postoperative outcomes.

    Poor communication between surgical and anesthesia unit personnel may jeopardize patient safety.  Review reports from a national survey on patient safety performed at 17 units 2011-2013 were analyzed in order to identify strategies to reduce risks related to the interaction between surgery and anesthesia. The reports were reviewed in this study by an independent group in order to extract findings related to communication between anesthesia and surgical unit personnel. Suggested strategies to improve patient safety included: uniform national health declaration forms; consistent use of admission notes; uniform systems for documenting medical information; multidisciplinary forum for evaluation of high-risk patients; weekly and daily scheduling of surgical programs; application of the WHO check list; open dialog during surgery; oral and written reports from the surgeon to the postoperative unit; and combined mortality and morbidity conferences.

    Problems associated with prosthetic graft replacement are stenosis at the anastomosis site and thrombus formation on the inner surface. Cilostazol is known to have antiplatelet activity and inhibit vascular smooth muscle cell proliferation and neointima thickening. A cilostazol derivative, (-)-6-[3-[3-cyclopropyl-3-[(1R,2R)-2-hydroxycyclohexyl]ureido]-propoxy]-2-(1H)-quinolinone (K-134), has more potent anti-platelet activity and anti-neointimal thickening activity than cilostazol in the in-vitro platelet aggregation and in-vivo anti-hyperplastic activity assay. The aim of this study was to investigate effects of cilostazol and K-134 on thrombus formation and neointimal thickening at the site of prosthetic graft replacement. Beagle dogs underwent infrarenal abdominal aortic resection with straight Dacron graft replacement, which were allocated to the control, cilostazol, and K-134 groups. Two dogs were dead without confirming the cause of death. After 6 months, all dogs were necropsied. All prosthetic grafts were patent in each group. Ratios of red thrombus to prosthetic graft area were 0.3+/-6.4%, and 3.3+/-4.5% in the cilostazol and K-134 groups, respectively, which were significant different from that in the control group (24.4+/-16.8%). However, no clear difference was seen among the 3 groups with respect to neointimal thickness (control group, 0.70+/-0.13 mm; cilostazol group, 0.59+/-0.14 mm; K-134 group, 0.67+/-0.14 mm). Cilostazol and K-134 significantly inhibited thrombus formation on the inner surface of the prosthetic graft at 6 months after graft replacement. Neointimal thickening on the inner surface was slight even in control-group animals, and the effects of cilostazol and K-134 on such thickening were unclear.

    Full Text Available Background: Post-operative nausea and vomiting is one of the most common and distressing complications after anesthesia and surgery. It may lead to serious post-operative complications. Ramosetron is a newer 5-HT3 receptor antagonist and has more potent and longer duration of antiemetic effects compared to first generation 5HT3 receptor antagonists. The purpose of this study was to compare the efficacy of Ramosetron for the prevention of post-operative nausea and vomiting with that of Ondansetron in patients undergoing abdominal surgeries under general anesthesia. Methods: In this randomized, double-blind study, 60 patients, 18-60 years of both genders falling under ASA I-II category scheduled for abdominal surgery were included. Group I received I.V ramosetron 0.3 mg while group II received I.V Ondansetron 4 mg at the time of extubation. The standard general anesthetic technique was used throughout. Postoperatively the incidences of nausea, vomiting, and safety assessments were performed at 1, 2, 6, and 24 h during the first 24 h after surgery. Results: There were no differences between groups with respect to patient demographics. The percentage of patients who had complete response (no PONV, and no need for another rescue antiemetic from 0 to 24 h after anesthesia was 56% with ramosetron and 33% with ondansetron. The corresponding rates at 1, 2, 6, and 24 h after anesthesia were 76% and 63%, 76% and 50%, 100 and 83%, 100 and 93%, respectively. Safety profiles of the two drugs were comparable, as no clinically serious adverse effects caused by study drugs were observed in either of the groups. Conclusion: Our study concludes that prophylactic therapy with ramosetron is highly efficacious than ondansetron in preventing PONV in patients undergoing abdominal surgery under general anesthesia.

    Data on safety and efficacy of robot-assisted radical prostatectomy (RARP) after previous abdominal surgery are scarce. Hence, we assessed perioperative, oncological and functional outcomes, and complications of RARP in patients with previous abdominal surgery after 1-year minimum follow-up. Prospectively collected data from 339 consecutive patients undergoing transperitoneal RARP by a single surgeon (AM) between November 2008 and May 2014 were analysed. Complications were classified according to Modified Clavien System. Biochemical recurrence (BCR) was defined as two consecutive PSA values ≥ 0.2 ng/ml. Functional outcomes were assessed using validated, self-administered questionnaires. In particular, only patients undergoing nerve-sparing RARP with no erectile dysfunction (baseline IIEF-5 score >21) and no use of phosphodiesterase-5 inhibitors preoperatively who were interested in erections and required no adjuvant therapy (radiation, orchiectomy and androgen-deprivation therapy) were evaluated concerning potency recovery. Patients without and with previous abdominal surgery were compared using Mann-Whitney and chi-square tests (or Fisher exact test). On 339 patients, 247 (71.6%) had not undergone previous abdominal surgery (Group 1) and 92 (28.4%) were pre-operated (Group 2). There were no statistically significant differences between Groups 1 and 2 regarding mean operative time (260 vs. 257 min; p = 0.597), median number of resected nodes (16 vs. 17; p = 0.484), mean length of stay (7.2 vs. 7.1 d; p = 0.151), positive surgical margin (12.5% vs. 16.3%; p = 0.233) and complication rates (26.7% vs. 31.5%; p = 0.187). Median (IQR) follow-up was 36 (12-48) months. For Groups 1 and 2, BCR-free survival rates were 78.5% and 79.8% (p = 0.467); continence rates were 97.9% and 100% (p = 0.329), whereas a potency recovery was achieved in 69.5% and 62.2% of patients (p = 0.460), respectively. Transperitoneal RARP is a safe and efficient treatment for

    In order to rigorously validate techniques for image-guided liver surgery (IGLS), an accurate mock representation of the intraoperative surgical scene with quantifiable localization of subsurface targets would be highly desirable. However, many attempts to reproduce the laparoscopic environment have encountered limited success due to neglect of several crucial design aspects. The laparoscopic setting is complicated by factors such as gas insufflation of the abdomen, changes in patient orientation, incomplete organ mobilization from ligaments, and limited access to organ surface data. The ability to accurately represent the influences of anatomical changes and procedural limitations is critical for appropriate evaluation of IGLS methodologies such as registration and deformation correction. However, these influences have not yet been comprehensively integrated into a platform usable for assessment of methods in laparoscopic IGLS. In this work, a mock laparoscopic liver simulator was created with realistic ligamenture to emulate the complexities of this constrained surgical environment for the realization of laparoscopic IGLS. The mock surgical system reproduces an insufflated abdominal cavity with dissectible ligaments, variable levels of incline matching intraoperative patient positioning, and port locations in accordance with surgical protocol. True positions of targets embedded in a tissue-mimicking phantom are measured from CT images. Using this setup, image-to-physical registration accuracy was evaluated for simulations of laparoscopic right and left lobe mobilization to assess rigid registration performance under more realistic laparoscopic conditions. Preliminary results suggest that non-rigid organ deformations and the region of organ surface data collected affect the ability to attain highly accurate registrations in laparoscopic applications.

    The infusion of large amounts of Ringer's lactate prolongs the functional gastrointestinal recovery time and increases the number of complications after open abdominal surgery. We performed an open-labelled clinical trial to determine whether hydroxyethyl starch or Ringer's lactate exerts these adverse effects when the surgery is performed by laparoscopy. Eighty-eight patients scheduled for major abdominal cancer surgery (83% by laparoscopy) received a first-line fluid treatment with 9 ml/kg of either 6% hydroxyethyl starch 130/0.4 (Voluven) or Ringer's lactate, just after induction of anaesthesia; this was followed by a second-line infusion with 12 ml/kg of either starch or Ringer's lactate over 1 hour. Further therapy was managed at the discretion of the attending anaesthetist. Outcome data consisted of postoperative gastrointestinal recovery time, complications and length of hospital stay. The order of the infusions had no impact on the outcome. Both the administration of ≥ 2 L of Ringer's lactate and the development of a surgical complication were associated with a longer time period of paralytic ileus and food intolerance (two-way ANOVA, P food intolerance time amounted to 2 days each. The infusion of ≥ 1 L of hydroxyethyl starch did not adversely affect gastrointestinal recovery. Ringer's lactate, but not hydroxyethyl starch, prolonged the gastrointestinal recovery time in patients undergoing laparoscopic cancer surgery. Surgical complications prolonged the hospital stay.

    Full Text Available Abstract Background Emergency abdominal surgery carries a 15% to 20% short-term mortality rate. Postoperative medical complications are strongly associated with increased mortality. Recent research suggests that timely recognition and effective management of complications may reduce mortality. The aim of the present trial is to evaluate the effect of postoperative intermediate care following emergency major abdominal surgery in high-risk patients. Methods and design The InCare trial is a randomised, parallel-group, non-blinded clinical trial with 1:1 allocation. Patients undergoing emergency laparotomy or laparoscopic surgery with a perioperative Acute Physiology and Chronic Health Evaluation II score of 10 or above, who are ready to be transferred to the surgical ward within 24 h of surgery are allocated to either intermediate care for 48 h, or surgical ward care. The primary outcome measure is all-cause 30-day mortality. We aim to enrol 400 patients in seven Danish hospitals. The sample size allows us to detect or refute a 34% relative risk reduction of mortality with 80% power. Discussion This trial evaluates the benefits and possible harm of intermediate care. The results may potentially influence the survival of many high-risk surgical patients. As a pioneer trial in the area, it will provide important data on the feasibility of future large-scale randomised clinical trials evaluating different levels of postoperative care.

    Patients with severe cardiovascular disease are frequently hemodynamically unstable during abdominal surgery. Improving the safety of such patients by stabilizing intraoperative hemodynamics remains a major concern for anesthesiologists. Transversus abdominis plane (TAP) block in combination with general anesthesia may facilitate optimum anesthetic management of these high-risk patients. Patients with cardiovascular disease classified as American Society of Anesthesiologists (ASA) physical status 3 were enrolled. The patients were undergoing elective abdominal surgery and were randomized to a group receiving general anesthesia and TAP block (Group T, N.=33) or a group receiving general anesthesia alone (Group G, N.=35). We compared the groups for intraoperative hemodynamic stability, anesthesia emergence time, amounts of anesthetics and opioids given, and frequency of emergency treatment with cardiovascular agents. A preliminary study demonstrated that systolic blood pressure and heart rate were maintained stable within 70-110% of their preanesthesia values throughout surgery in ASA 1 elderly patients without cardiovascular disease. Thus, the hemodynamically stable time was defined as the time when systolic blood pressure and heart rate were 70-110% of their preanesthesia values. The ratio of hemodynamically stable time to total operative time was used as an index of hemodynamic stability. The median (minimum-maximum) percentage of hemodynamically stable time was longer in Group T (91[50-100]%) than Group G (79[40-91]%, Pabdominal surgery in patients with severe cardiovascular disease, combining TAP block with general anesthesia promotes intraoperative hemodynamic stability and early emergence from anesthesia.

    Transversus abdominis plane (TAP) block used for management of surgical abdominal pain by injecting local anesthetics into the plane between the internal oblique and transversus abdominis muscles. We aimed to explore the effect of adding morphine to bupivacaine in ultrasound guided TAP-block in patients undergoing lower abdominal cancer surgery. Randomized, double-blind, prospective study. Clinical trial identifier: NCT02566096. Academic medical center. Sixty patients were enrolled in this study after ethical committee approval. Patients divided into 2 groups (30 each): Bupivacaine group (GB): given ultrasound guided TAP-block 20ml 0.5% bupivacaine diluted in 20ml saline; Morphine group (GM): given ultrasound guided TAP-block with 20ml 0.5% bupivacaine+10mg morphine sulphate diluted in 20ml saline. Patients were observed for total morphine consumption, time for first request of rescue analgesia, sedation scores, hemodynamics and side effects for 24h postoperatively. Morphine added to bupivacaine in TAP block compared to bupivacaine alone reduced total morphine consumption (5.33±1.28mg) (10.70±3.09mg) respectively (p0.05). Addition of morphine to bupivacaine in TAP block is effective method for pain management in patients undergoing major abdominal cancer surgery without serious side effects.

    Full Text Available Ovarian cancer remains one of the most aggressive gynecologic malignancies with high capacity to recur even in cases submitted to surgery with curative intent. However, even in these cases the best therapeutic option in order to achieve a good control of the disease remains radical surgery. We present the case of a 65-year-old patient diagnosed submitted to surgery for stage IIIC ovarian cancer five years before. At two years follow up she was diagnosed with an isolated recurrence at the level of the hepatic pedicle which was successfully removed. At 18 months follow up she was diagnosed with a large recurrence in the left superior abdominal quadrant and a liver metastasis which were resected. At 18 months follow up she is free of recurrent disease.

    To evaluate the feasibility and safety of single-incision laparoscopic surgery for totally extraperitoneal inguinal hernia repair (SILS-TEP) with previous lower abdominal surgery (PLAS). A retrospective analysis of 350 patients undergoing SILS-TEP for a primary inguinal hernia from January 2012 to December 2015 at Osaka Police Hospital was performed, and the outcomes of the patients with and without PLAS were compared. SILS-TEP was performed in 84 patients with PLAS and 266 patients without PLAS. Appendectomy was the most common previous operative procedure. There were more patients with an ASA score of ≥3 in the PLAS group than in the control group (p < 0.05). The mean operative time, and the rates of conversion and postoperative complications were comparable between the two groups. There were no cases of recurrence in either group. SILS-TEP could be safely performed in patients with PLAS and achieved better cosmetic outcomes than conventional laparoscopic surgery.

    To explore the feasibility and clinical efficacies of umbilical one-trocar laparoendoscopic surgery versus trans-umbilicus and abdominal wall two-trocar laparoendoscopic surgery in the treatment of pediatric hydrocele. Retrospective comparative analysis was conducted for 78 cases of hydrocele undergoing laparoscopic surgery at our hospital from January 2012 to May 2012. They were divided into two groups of umbilical one-trocar laparoscopic surgery (one-trocar, n = 32) and trans-umbilicus and abdominal wall two-trocar laparoscopic surgery (two-trocar, n = 46). And their profiles of operative duration, post-operative hospital stay and treatment cost were compared. All procedures were successful. No case converted into open surgery. Visual field of both methods was similar, but two-trocar group had a flexible visual angle. During a follow-up period of 3 - 6 months, there was no occurrence of postoperative complications. The average operative duration was (20 ± 10) min at one side and (31 ± 11) min at both sides in one-trocar group versus (20 ± 8) min and (29 ± 9) min in two-trocar group. There were no statistical significance (all P > 0.05). Cost in one-trocar group was (5199 ± 599) yuan RMB and (5117 ± 684)yuan RMB in two-trocar group (P > 0.05). Trans-umbilicus laparoendoscopic one-trocar surgery is both feasible and safe in the treatment of pediatric hydrocele. Compared with two-trocar laparoscopic surgery, both approaches are similar in terms of operative duration, post-operative hospital stay and treatment cost. Since there is a single hidden navel scar, the former is labor-saving, may be handled by one operator and offers better cosmetic outcomes.

    The authors consider their early results in radiological drainage management of abscesses and fistulas complicating abdominal surgery by integrated use of angiographic materials and interventional methods. Twenty-five patients, affected by isolated (32%) or communicating (68%) abscesses, were treated. Cavity obliteration and clinical recovery were obtained in 18 patients (72%), partial success in 1 (4%); a patient was treated unsuccessfully. Five patients were not evaluated because they died or underwent surgery again. Average drainage intervall was 54 days. Drainage management was carried out by replacement of surgical catheters and fibrin occlusion. Fibrin occlusion was performed in 7 patients with the following results: 3 successes, one partial success and one failure. Two cases were not evaluated. Although a comparison with a control group was not performed, the authors consider the procedure a safe, economic and simple method for abdominal abscess management

    Endovascular aneurysm repair (EVAR) is an alternative treatment for ruptured abdominal aortic aneurysms (rAAA) in hemodynamically (hd) stable patients. Treatment for patients with hd-unstable rAAA remains controversial. The aim of this study was to compare the outcomes of EVAR and open surgery (OS) in hd-stable and hd-unstable rAAA patients using meta-analysis. The first part of this study included 48 articles that reported the treatment outcomes of rAAA managed with EVAR (n = 9610) and OS (n = 93867). The second part, which is the focus of this study, included 5 out of 48 articles, which further reported treatment results in hd-stable (n = 198) and hd-unstable (n = 185) patients. When heterogeneity among the groups was observed, a random-effects model was used to calculate the adjusted odds ratios (OR) or in cases of non-heterogeneity, a fixed-effects model analysis was employed. In the first part of this study, the in-hospital mortality rate was found to be lower in the EVAR group than in the OS group (29.9 vs 40.8 %; OR 0.59; 95 % CI 0.52-0.66; P OS. The total mortality was 147/383 (38.4 %), while the mortality of the EVAR group and the OS group was 25.7 % (39/152) and 46.8 % (108/231), respectively. In the hd-stable group, the in-hospital mortality after EVAR was significantly lower than that after OS [18.9 % (18/95) vs 28.2 % (29/103); OR 0.47; 95 % CI 0.22-0.97; P = 0.04]. For the hd-unstable rAAA patients, the in-hospital mortality after EVAR was significantly lower than that after OS [36.8 % (21/57) vs 61.7 % (79/128); OR 0.40; 95 % CI 0.20-0.79; P OS, EVAR in hd-unstable rAAA patients is associated with improved outcomes. Available publications are currently limited; thus, the best treatment strategy for this subgroup of patients remains unclear. Further clinical studies are needed to provide more detailed data, such as the shock index and long-term results.

    Early stages of Crohn's disease [CD] are predominantly inflammatory and early treatment could be useful to change the natural history of CD. We aimed to evaluate the impact of early treatment in our cohort of CD patients. We retrospectively reviewed clinical records of all CD patients at our centre who have received immunomodulators. Time from diagnosis to first CD-related major abdominal surgery or end of follow-up was considered. Dates of diagnosis, of starting immunomodulators (thiopurines / anti-tumour necrosis factor [TNF]), and of the first CD-related surgery when appropriate were collected. Of 422 patients who received thiopurines, 189 operated patients started thiopurines after a median of 117 months (interquartile range [IQR] 44-196) since diagnosis; non-operated patients, after a median of 30 months [IQR 6-128], p risk of major abdominal surgery in Crohn's disease.

    Full Text Available A classification of intraoperative cardio-vascular complications (CVC was performed, based on data from 466 patients subjected to emergency surgery, due to severe abdominal surgical diseases or traumas, in accordance with the severe criteria of ACC/AHA for CVC in noncardiac surgery. There were 370 intraoperative CVC registered, distributed as follows: groups with low risk (148, moderate risk (200, and high risk (22. Patient groups were formed, according to the CVC risk level, during the intraoperative period, for which the determinant factor for the group distribution of patients was the complication with the highest risk. Individual data was collected for each patient, based on 65 indices: age, physical status, diseases, surgical interventions, anaesthesiological information, intra and postoperative cardio-vascular complications, disease outcome, causes of death, cardiovascular disease anamnesis, anamnesis of all other nonsurgical diseases present, laboratory results, results from all imaging and instrumental examinations, etc. On the basis of these indices, a new distribution of the risk factors was implemented, into groups with different levels of risk of CVC during intraoperative period. This result is a solid argument, substantiating the proposal to introduce these adjustments for determining the severity of CVC in the specific conditions of emergency abdominal surgery.

    to evaluate the ventilatory function by Peak Expiratory Flow (PEF) in the immediate pre and postoperative periods of patients undergoing elective surgical procedures in the upper abdomen. we conducted a prospective cohort study including 47 patients admitted to the Hospital Regional de Mato Grosso do Sul from July to December 2014, who underwent elective surgeries of the upper abdomen, and submiited to spirometric evaluation and measurement of PEF immediately before and after surgery. of the 47 patients, 22 (46.8%) were male and 25 (53.20%) female. The mean preoperative PEF was 412.1±91.7, and postoperative, 331.0±87.8, indicating significant differences between the two variables. Men had higher PEF values than women, both in the pre and postoperative periods. There was a reasonable inverse correlation between age and decreased PEF. Both situations showed statistical significance (pvalores de PFE do que o feminino, tanto no pré-cirúrgico quanto no pós-cirúrgico. Observou-se razoável correlação inversamente proporcional entre as variáveis idade e diminuição do PFE. Ambas as situações mostraram significância estatística (pvalores de PFE tanto no pré como no pós-operatório. O grupo composto por portadores de co-morbidades (HAS e/ou DM) apresentou menores valores de PFE tanto no pré como no pós-operatório (p=0,005). Em ambos os grupos, o pós-operatório determinou uma diminuição significativa do PFE (p<0,001). O tipo de cirurgia realizada e o tipo de anestesia não mostraram diferenças significantes em relação ao PFE. as variáveis mais implicadas na diminuição da função ventilatória, avaliadas através da PFE, foram: idade avançada, tabagismo e presença de comorbidades.

    Transversus abdominis plane block is a safe, simple and effective technique of providing analgesia for lower abdominal surgeries with easily identifiable landmarks. To compare the analgesic efficacy of transversus abdominis plane block with that of direct infiltration of local anesthetic into surgical incision in lower abdominal procedures. Prospective randomized controlled trial in lower abdominal surgeries done under general anesthesia. 52 ASA I-II patients undergoing lower abdominal gynecological procedures under general anesthesia were divided randomly into two groups each after written informed consent. A bilateral TAP block was performed on Group T with 0.25% bupivacaine 0.6 ml/kg with half the volume on either side intra-operatively after skin closure before extubation using a short bevelled needle, whereas Group I received local infiltration intra-operatively after skin closure with the same amount of drug. The time taken for the first rescue analgesic and visual analog score (VAS) was noted, following which, the patient was administered intravenous morphine 0.1 mg/kg and connected to an intravenous patient controlled analgesia system with morphine for 24 hrs from the time of block administration. 24 h morphine requirement was noted. VAS and sedation scores were noted at 2, 4, 6 and 24 h postoperatively. The results were analyzed with SPSS 16. A P value < 0.05 was considered significant. Duration of analgesia and 24 h morphine requirement was analysed by Student's t-test. VAS scores, with paired comparisons at each time interval, were performed using the t-test or Mann-Whitney U-test, as appropriate. Categorical data were analyzed using Chi square or Fisher's exact test. In Group T, the time to rescue analgesic was significantly more and the VAS scores were lower (P = 0.001 and 0.003 respectively). The 24 hr morphine requirement and VAS at 2, 4, 6 and 24 h were less in the Group T (P = 0.001). Incidence of PONV was significant in Group I (P = 0

    Colonoscopy is widely used for management of colorectal diseases. A history of abdominal or pelvic surgery is a well-recognized factor associated with difficult colonoscopy. Although water exchange colonoscopy (WEC) was effective in small groups of male U.S. veterans with such a history, its application in other cultural settings is uncertain. To investigate the application of WEC in such patients. Prospective, randomized, controlled, patient-blinded study. Tertiary-care referral center in China. Outpatients with prior abdominal or pelvic surgery undergoing unsedated diagnostic, screening, or surveillance colonoscopy. Patients were randomized to examination by either WEC or conventional air colonoscopy (AC). Cecal intubation rate. A total of 110 patients were randomized to the WEC (n = 55) or AC (n = 55) group. WEC significantly increased the cecal intubation rate (92.7% vs 76.4%; P = .033). The maximum pain scores (± standard deviation) were 2.1 ± 1.8 (WEC) and 4.6 ± 1.7 (AC), respectively (P WEC would be willing to have a repeat unsedated colonoscopy (90.9% vs 72.7%, P = .013). Single center; unblinded but experienced endoscopists. This randomized, controlled trial confirms that the water exchange method significantly enhanced cecal intubation in potentially difficult colonoscopy in unsedated patients with prior abdominal or pelvic surgery. The lower pain scores and higher proportion accepting repeat of the unsedated option suggest that WEC is promising. It may enhances compliance with colonoscopy in specific populations.

    Full Text Available A 21-year-old female patient with abdominal pain, vomiting and constipation was admitted to the hospital with the possible diagnosis of diabetic ketoacidosis. Due to increased abdominal pain and constipation the patient underwent a surgery with the diagnosis of ileus. However, no pathological findings were found in the abdominal organs apart from serous fluid in the abdominal cavity. The patient became hypertensive, tachycardic and had an episode of seizures postoperatively. Neurological manifestations with unexplained abdominal pain indicated a diagnosis of acute intermittent porphyria (AIP. Acute intermittent porphyria diagnosis is based on elevated urinary δ-aminolevulinic acid (ALA and porphobilinogen (PBG levels as well as hydroxymethylbilane synthase (HMBS IVS13-2 A>G heterozygous mutation. Familial Mediterranean Fever (FMF gene mutations were not confirmed. Porphyria should be considered in the differential diagnosis of patients with recurrent abdominal pain, neurological symptoms and lack of FMF gene polymorphism.

    Full Text Available Abstract Cardiac angiosarcomas are extremely rare in childhood, they are rapidly progressive tumours that often present themselves as diagnostic dilemmas, resulting in delayed diagnosis. Also, extracardiac manifestations, including abdominal pain, are extremely rare in patients with intracardiac tumors. We herein present the case of a 15-year-old girl who presented with abdominal pain. Echocardiography and thoracic computed tomography showed right atrial mass. The patient underwent surgery, chemotherapy, and radiotherapy. Eight months after treatment, abdominal recurrence was detected. The abdominal mass was resected, and radiotherapy and new chemotherapy protocol were given. The present case illustrates a rare case of primary cardiac angiosarcoma posing a diagnostic dilemma in an adolescent girl.

    Studies were undertaken to determine if computed tomography (CT) could reliably assist physical examination in the initial assessment of blunt abdominal trauma, and also to examine how various abdominal injuries were managed with the guidance of CT. A total of 255 patients underwent emergency abdominal CT following blunt abdominal trauma over a period of seven years. One hundred and fifty two patients had abnormal CT scans, including 58 hepatic, 36 renal, 25 splenic and 9 pancreatic injuries as well as 67 patients with intra-abdominal hemorrhage and 21 patients with free abdominal air. A comparative study on the detection of pneumoperitoneum revealed CT to be far superior to plain radiography. One hundred and three patients had normal CT scans, all of whom were managed nonoperatively, except for three false-negative cases and two nontherapeutic cases. The patients with injury to the parenchymal organs were given nonoperative treatment if they had stable vital signs and no evidence of associated injuries demanding immediate surgery and the majority of these patients were managed well nonoperatively. CT was thus found to be a useful adjunct in the management of victims of blunt abdominal trauma, since in a rapid and noninvasive fashion, CT accurately defined the extent of parenchymal organ injury and also disclosed any other abdominal injuries.

    Combined abdominal and breast surgery presents a convenient and relatively cost-effective approach for accomplishing both procedures. This study is the largest to date assessing the safety of combined procedures, and it aims to develop a simple pretreatment risk stratification method for patients who desire a combined procedure. All women undergoing abdominoplasty, panniculectomy, augmentation mammaplasty, and/or mastopexy in the TOPS database were identified. Demographics and outcomes for combined procedures were compared to individual procedures using χ(2) and Student's t-tests. Multiple logistic regression provided adjusted odds ratios for the effect of a combined procedure on 30-day complications. Among combined procedures, a logistic regression model determined point values for pretreatment risk factors including diabetes (1 point), age over 53 (1), obesity (2), and 3+ ASA status (3), creating a 7-point pretreatment risk stratification tool. A total of 58,756 cases met inclusion criteria. Complication rates among combined procedures (9.40%) were greater than those of aesthetic breast surgery (2.66%; P risk (0 points total) with a 9.78% complication rates. Medium-risk patients (1 to 3 points) had a 16.63% complication rate, and high-risk (4 to 7 points) 38.46%. Combining abdominal and breast procedures is safe in the majority of patients and does not increase 30-day complications rates. The risk stratification tool can continue to ensure favorable outcomes for patients who may desire a combined surgery. 4 Risk. © 2015 The American Society for Aesthetic Plastic Surgery, Inc.

    qualitative stage, 10 semi-structured interviews were performed with men selected according to purposeful criteria of level of schooling and number of children. Then, a structured form was provided for 202 men, drawn from the complete list of those who had had a vasectomy between 1998 and 2004. A thematic analysis of the content of the semi-structured interviews was carried out. The quantitative data were keyboarded and a descriptive analysis was conducted. RESULTS: It was observed that 97% of the men were satisfied because they had undergone the surgery and only a few of them mentioned undesired effects. Among the few dissatisfied men, only one had had vasectomy reversal because he lived with a new partner and wanted to have children; among the others, dissatisfaction was due to the pain caused by the surgical procedure. The majority of the interviewees attributed to vasectomy changes for the best in their health, body, general relationship with their families and wives, in their sexual life and economic situation. The idea that prevailed was that vasectomy had brought only benefits. The possibility of regret was mentioned by the interviewees as something that would not happen to them. CONCLUSION: The results of this study allowed to verify that men who decide to have a vasectomy tend to see the method as a factor of positive changes, mainly in the sexual life and in the relationship with the partner and family in general.

    Full Text Available Background/Aim. Abdominal aorta aneurysm (AAA represents a pathological enlargment of infrarenal portion of aorta for over 50% of its lumen. The only treatment of AAA is a surgical reconstruction of the affected segment. Until the late XX century, surgical reconstruction implied explicit, open repair (OR of AAA, which was accompanied by a significant morbidity and mortality of the treated patients. Development of endovascular repair of (EVAR AAA, especially in the last decade, offered another possibility of surgical reconstruction of AAA. The preliminary results of world studies show that complications of such a procedure, as well as morbidity and mortality of patients, are significantly lower than with OR of AAA. The aim of this paper was to present results of comparative clinical prospective study of early inflammatory response after reconstruction of AAA between endovascular and open, conventional surgical technique. Methods. A comparative clinical prospective study included 39 patients, electively operated on for AAA within the period of December 2008 - February 2010, divided into two groups. The group I counted 21 (54% of the patients, 58-87 years old (mean 74.3 years, who had been submited to EVAR by the use of excluder stent graft. The group II consisted of 18 (46% of the patients, 49-82 (mean 66.8 years, operated on using OR technique. All of the treated patients in both groups had AAA larager than 50 mm. The study did not include patients who have been treated as urgent cases, due to the rupture or with simptomatic AAA. Clinical, biochemical and inflamatory parameters in early postoperative period were analyzed, in direct postoperative course (number of leucocytes, thrombocytes, serum circulating levels of cytokine - interleukine (IL-2, IL-4, IL-6 and IL-10. Parameters were monitored on the zero, first, second, third and seventh postoperative days. The study was approved by the Ethics Commitee of the Military Medical Academy. Results

    Intra-abdominal surgical intervention can cause the development of intra-peritoneal adhesions. To reduce this problem, different agents have been tested to minimize abdominal adhesions; however, the optimal adhesion prophylaxis has not been found so far. Therefore, the A-Part(®) Gel was developed as a barrier to diminish postsurgical adhesions; the aim of this randomized controlled study was a first evaluation of its safety and efficacy. In this prospective, controlled, randomized, patient-blinded, monocenter phase I-II study, 62 patients received either the hydrogel A-Part-Gel(®) as an anti-adhesive barrier or were untreated after primary elective median laparotomy. Primary endpoint was the occurrence of peritonitis and/or wound healing impairment 28 ± 10 days postoperatively. As secondary endpoints anastomotic leakage until 28 days after surgery, adverse events and adhesions were assessed until 3 months postoperatively. A lower rate of wound healing impairment and/or peritonitis was observed in the A-Part Gel(®) group compared to the control group: (6.5 vs. 13.8 %). The difference between the two groups was -7.3%, 90 % confidence interval [-20.1, 5.4 %]. Both treatment groups showed similar frequency of anastomotic leakage but incidence of adverse events and serious adverse events were slightly lower in the A-Part Gel(®) group compared to the control. Adhesion rates were comparable in both groups. A-Part Gel(®) is safe as an adhesion prophylaxis after abdominal wall surgery but no reduction of postoperative peritoneal adhesion could be found in comparison to the control group. This may at least in part be due to the small sample size as well as to the incomplete coverage of the incision due to the used application. NCT00646412.

    To explore the clinical effects of pedicled omentum covering and wrapping the ureteral anastomosis to prevent ureteral anastomotic leakage after surgery of abdominal and pelvic tumors. Clinical data of 64 patients with ureteral anastomosis after surgery of abdominal and pelvic tumors treated in our department from May 2005 to May 2012 were retrospectively analyzed. They were assigned into 2 groups. There were 23 patients of ureteral anastomosis combined with pedicled omentum surrounding and wrapping the anastomotic site (optimization group), and 41 cases of ureteral anastomosis alone (control group). The clinical data of all the 64 patients were reviewed and the therapeutic effects of the two treatment approaches were compared. At one week after the operation, there were 8 cases (34.8%, 8/23) with ureteral anastomotic fistula in the optimization group and 31 cases (75.6%, 31/41) in the control group (P = 0.010). In the postoperative days 1-3, the average drainage everyday from abdominal tube around the anastomotic site was 260.4 ml and 320.8 ml, respectively (P = 0.446). The average drainage volume everyday was 80.5 ml and 160.5 ml from the postoperative day 4 to day 7 (P = 0.015). The average time of removal of the peritoneal cavity drainage tube was 18.5 d in the optimization group and 32.6 d postoperatively in the control group (P = 0.015). Covering and wrapping the ureteral anastomosis with pedicled omentum can promote the rapid adhesion of surrounding tissues to reduce urine leakage and postoperative complications, and shorten the surgical treatment cycle.

    Full Text Available Objective: The aim of this study was to evaluate the effectiveness of implementing a physical therapy guideline for patients undergoing upper abdominal surgery (UAS in reducing the incidence of atelectasis and length of hospital stay in the postoperative period. Materials and methods: A “before and after” study design with historical control was used. The “before” period included consecutive patients who underwent UAS before guideline implementation (intervention. The “after” period included consecutive patients after guideline implementation. Patients in the pre‐intervention period were submitted to a program of physical therapy in which the treatment planning was based on the individual experience of each professional. On the other hand, patients who were included in the post‐intervention period underwent a standardized program of physical therapy with a focus on the use of additional strategies (EPAP, incentive spirometry and early mobilization. Results: There was a significant increase in the use of incentive spirometry and positive expiratory airway pressure after guideline implementation. Moreover, it was observed that early ambulation occurred in all patients in the post‐intervention period. No patient who adhered totally to the guideline in the post‐intervention period developed atelectasis. Individuals in the post‐intervention period presented a shorter length of hospital stay (9.2 ± 4.1 days compared to patients in the pre‐intervention period (12.1 ± 8.3 days (p < 0.05. Conclusion: The implementation of a physical therapy guideline for patients undergoing UAS resulted in reduced incidence of atelectasis and reduction in length of hospital stay in the postoperative period.

    ós-operatório de cirurgia abdominal eletiva é muito freqüente. A maioria dos DPPO é autolimitada, evoluindo de modo assintomático. A ecografia na constatação do DPPO mostrou-se efetiva e sua utilização merece ser difundida.BACKGROUND: Pleural effusion is frequently seen on imaging examinations following elective abdominal surgery and has no clinical significance in most patients. This condition should be distinguished from pulmonary complications that require treatment. OBJECTIVE: To prospectively determine the incidence of pleural effusion in patients submitted to elective abdominal surgery using ultrasound (US, and to assess the possible association with risk factors related to the patients and anesthetic-surgical procedures. MATERIALS AND METHODS: Thirty-seven patients, 21 (56.8% female, and 16 (43.2% male aged 29 to 76 years submitted to elective abdominal surgery were evaluated. US was performed preoperatively and 48 hours after surgery in all patients. Associated risk factors were also assessed - age > 60 years, sex, obesity, smoking history, alcoholism and associated diseases -, and anesthetic-surgical procedure - cancer resection, class ASA > 2, duration of surgery, longitudinal incision and incision > 15 cm. Biliar lithiasis (43.2% and gastrointestinal cancer (43.2% were the main causes leading to surgery. RESULTS: The incidence of postoperative pleural effusion (PPE detected by US was 70.3% (26/37. Two of these patients (5.4% developed pulmonary complications, and one died. The risk factors age > 60 years, smoking history, alcoholism, obesity and associated diseases had no influence on the development of the PPE whereas cancer resection, class ASA > 2, longitudinal incision and incision > 15 cm were significantly statistically associated with the presence of PPE. PPE developed even during antibiotic therapy. The duration of hospitalization was more than 2.4 longer in the patients with PPE. CONCLUSION: PPE is a very frequent condition observed in patients

    EstabLishment of hepato-pancreato-biliary (HPB) surgery and abdominal organ transplantation as defined subspecialties of general surgery has been boosted over the Last decade. However, the affiliation (independent service vs. integration within the division of surgery), the training course (transplantation vs. surgical oncology) and the referral patterns are still controversial. Dedicated HPB and transplantation units were defined within the surgical division of the Tel Aviv Medical Center. The principles of operation included muttidisciplinary expert teams, unified and standard treatment protocols, exposure and involvement of all residents and attending surgeons of the division to patients, decision-making and perioperative care, peer review and periodic publication of clinical results. Between the years 2003-2007, 870 major HPB procedures were performed: 70 Liver transplants (9 from live donors), 100 organ procurements, 165 kidney and kidney-pancreas transplants (30% from Live donors), 250 hepatic resections of various types and indications, 35 complex biliary reconstructions and 250 pancreatectomies. The short- (morbidity and mortality) and long-term (survival and disease free survival) rates are compatible with the reported results from Centers of Excellence around the world. Operating HPB and transplantation surgery by trained experts and defined professional units, but within an academic surgical division, promotes the achievement of high volume and excellent results together with optimal exposure, education and training of the surgical residents.

    High-flow nasal cannula (HFNC) oxygen therapy is attracting increasing interest in acute medicine as an alternative to standard oxygen therapy; however, its use to prevent hypoxaemia after major abdominal surgery has not been evaluated. Our trial was designed to close this evidence gap. A multicentre randomised controlled trial was carried out at three university hospitals in France. Adult patients at moderate to high risk of postoperative pulmonary complications who had undergone major abdominal surgery using lung-protective ventilation were randomly assigned using a computer-generated sequence to receive either HFNC oxygen therapy or standard oxygen therapy (low-flow oxygen delivered via nasal prongs or facemask) directly after extubation. The primary endpoint was absolute risk reduction (ARR) for hypoxaemia at 1 h after extubation and after treatment discontinuation. Secondary outcomes included occurrence of postoperative pulmonary complications within 7 days after surgery, the duration of hospital stay, and in-hospital mortality. The analysis was performed on data from the modified intention-to-treat population. This trial was registered with ClinicalTrials.gov (NCT01887015). Between 6 November 2013 and 1 March 2015, 220 patients were randomly assigned to receive either HFNC (n = 108) or standard oxygen therapy (n = 112); all of these patients completed follow-up. The median duration of the allocated treatment was 16 h (interquartile range 14-18 h) with standard oxygen therapy and 15 h (interquartile range 12-18) with HFNC therapy. Twenty-three (21 %) of the 108 patients treated with HFNC 1 h after extubation and 29 (27 %) of the 108 patients after treatment discontinuation had postextubation hypoxaemia, compared with 27 (24 %) and 34 (30 %) of the 112 patients treated with standard oxygen (ARR 4, 95 % CI -8 to 15 %; p = 0.57; adjusted relative risk [RR] 0.87, 95 % CI 0.53-1.43; p = 0.58). Over the 7-day postoperative follow-up period

    The role of positive end-expiratory pressure in mechanical ventilation during general anaesthesia for surgery remains uncertain. Levels of pressure higher than 0 cm H2O might protect against postoperative pulmonary complications but could also cause intraoperative circulatory depression and lung injury from overdistension. We tested the hypothesis that a high level of positive end-expiratory pressure with recruitment manoeuvres protects against postoperative pulmonary complications in patients at risk of complications who are receiving mechanical ventilation with low tidal volumes during general anaesthesia for open abdominal surgery. In this randomised controlled trial at 30 centres in Europe and North and South America, we recruited 900 patients at risk for postoperative pulmonary complications who were planned for open abdominal surgery under general anaesthesia and ventilation at tidal volumes of 8 mL/kg. We randomly allocated patients to either a high level of positive end-expiratory pressure (12 cm H2O) with recruitment manoeuvres (higher PEEP group) or a low level of pressure (≤2 cm H2O) without recruitment manoeuvres (lower PEEP group). We used a centralised computer-generated randomisation system. Patients and outcome assessors were masked to the intervention. Primary endpoint was a composite of postoperative pulmonary complications by postoperative day 5. Analysis was by intention-to-treat. The study is registered at Controlled-Trials.com, number ISRCTN70332574. From February, 2011, to January, 2013, 447 patients were randomly allocated to the higher PEEP group and 453 to the lower PEEP group. Six patients were excluded from the analysis, four because they withdrew consent and two for violation of inclusion criteria. Median levels of positive end-expiratory pressure were 12 cm H2O (IQR 12-12) in the higher PEEP group and 2 cm H2O (0-2) in the lower PEEP group. Postoperative pulmonary complications were reported in 174 (40%) of 445 patients in the higher

    Previous abdominal wall surgery is viewed as a contraindication to abdominal free tissue transfer. We present two patients who underwent multiple abdominal liposuction procedures, followed by successful free deep inferior epigastric artery perforator flap. We review the literature pertaining to reliability of abdominal free flaps in those with previous abdominal surgery. Review of case notes and radiological investigations of two patients, and a PubMed search using the terms "DIEP", "deep inferior epigastric", "TRAM", "transverse rectus abdominis", "perforator" and "laparotomy", "abdominal wall", "liposuction", "liposculpture", "fat graft", "pfannenstiel", with subsequent appraisal of relevant papers by the first and second authors. Patient 1 had 3 episodes of liposuction from the abdomen for fat grafting to a reconstructed breast. Subsequent revision reconstruction of the same breast with DIEP flap was preceded by CT angiography, which demonstrated normal perforator anatomy. The reconstruction healed well with no ischaemic complications. Patient 2 had 5 liposuction procedures from the abdomen to graft fat to a wide local excision defect. Recurrence of cancer led to mastectomy and immediate reconstruction with free DIEP flap. Preoperative MR angiography demonstrated a large perforator right of the umbilicus, with which the intraoperative findings were consistent. The patient had an uneventful recovery and good healing with no fat necrosis or wound dehiscence. We demonstrate that DIEP flaps can safely be raised without perfusion-related complications following multiple liposuction procedures to the abdomen. The safe interval between procedures is difficult to quantify, but we demonstrate successful free flap after 16 months.

    Full Text Available Background: Regional anesthetic techniques can be used to alleviate postoperative pain in patients undergoing major upper abdominal surgery. Our aim was to evaluate the efficacy of bilateral ultrasound (US-guided rectus sheath (RS and transversus abdominis plane (TAP blocks for better perioperative analgesia. Patients and Methods: It is a prospective, observer-blinded, randomized clinical study. 40 eligible patients undergoing elective liver resection or Whipple procedure were included. All patients received a standardized anesthetic technique. Group 1 (n = 20 received preincisional US-guided bilateral RS and TAP blocks using 20 ml volume of bupivacaine 0.25% for each, and group 2 (n = 20 received local wound infiltration at end of surgery with 40 ml of bupivacaine 0.25%. A standardized postoperative analgesic regimen composed of intravenous paracetamol and a morphine patient-controlled analgesia (PCA. The use of intraoperative fentanyl and recovery room morphine boluses, PCA-administered morphine, pain scores as well as number of patients′ experienced postoperative nausea and vomiting in the ward at 6 and 24 h were recorded. Results: Group 1 patients received a significantly lower cumulative intraoperative fentanyl, significantly lesser boluses of morphine in postanesthesia care unit, as well, significantly lower cumulative 24 h postoperative morphine dosage than the group 2 patients. Pain visual analog scale scores were significantly lower at both 6 and 24 h postoperatively in TAP group when compared with the no-TAP group. There were no complications related to the TAP block procedures. No signs or symptoms of local anesthetic systemic toxicity were detected. Conclusion: The combination of bilateral US-guided RS and TAP blocks provides excellent perioperative analgesia for major upper abdominal surgery.

    To evaluate whether intraoperative high-dose remifentanil infusion increased local anesthetic consumption in postoperative epidural analgesia and postoperative pain scores compared with low-dose remifentanil infusion. Prospective, randomized controlled study. Operating room, university hospital. Thirty female patients scheduled for elective gynecological abdominal surgery. After epidural catheter placement and induction of general anesthesia, patients were randomly assigned to 2 anesthetic regimens. In the first group (high-dose remifentanil group), sevoflurane concentration was held constant at 1.2%, and the remifentanil infusion rate was titrated to maintain systolic blood pressure within 20% of baseline. In the second group (low-dose remifentanil group), the remifentanil infusion rate was held constant at 0.1μg/(kg min), and the sevoflurane concentration was titrated to maintain systolic blood pressure within 20% of baseline. As abdominal wall closure began, 6mL of 0.2% ropivacaine was administrated via epidural catheter; a patient-controlled analgesia device was set to deliver 4mL/h of 0.2% ropivacaine with 3μg/mL of fentanyl, with 2-mL incremental doses and a 15-minute lockout time. Local anesthetic consumption via postoperative epidural catheter and pain intensity with the Prince Henry pain scale were assessed for 48hours after surgery. The mean remifentanil infusion rate was 0.23μg/(kg min) in the high-dose remifentanil group, 2.3 times the rate used in the low-dose remifentanil group. The cumulative amount of local anesthetic used within 48hours of surgery was significant greater in the high-dose remifentanil group than in the low-dose remifentanil group (212±25mL vs. 181±35mL, respectively; Phigh-dose remifentanil infusion increased local anesthetic consumption in postoperative epidural analgesia relative to low-dose remifentanil.

    The use of a new therapeutic alternative involving cytoreductive surgery with perioperative intraperitoneal chemotherapy in the treatment of patients suffering from peritoneal carcinomatosis represents a new challenge for the multidisciplinary teams caring for these patients. Their post-operative progress and care needs, apart from differing from those of conventional patients, have not yet been completely defined or protocolised. In this presentation we explain the special characteristics of these patients compared to the usual surgical patients, the possible physiopathological mechanisms which may give rise to the different types of complications, the circumstances when a temporary abdominal closure is necessary, the ideal conditions required for an optimal technique, and finally our experience with the open vacuum abdomen technique in the treatment of the complications that appear in patients treated by this new triple combined therapy. Based on our personal experience in the treatment of 110 cytoreductions carried out between February 1997 and February 2007 on 71 patients suffering from peritoneal carcinomatosis of various origins. Of the 71 patients, 50 (70%) suffered some kind of complication during their postoperative evolution, 28 of them requiring re-operation for a Grade III-IV postoperative complication. The abdominal situation made a temporary closure desirable in 17 patients, having applied an open vacuum abdomen technique on every occasion. We study this group of patients according their original type of tumour and stage of the disease at the cytoreductive procedure, peritonectomies and visceral resections required, type of postoperative complications, treatment applied and evolution. A total of 52 open vacuum abdomen procedures were required (median, 2.8 per patient; range, 1-10) before the abdominal complication could be completely kept under control in these 17 patients. Only 2 postoperative intestinal fistulas were directly related to this

    Full Text Available In the work we present comparative results of treatment of patients with generalized secondary and tertiary peritonitis depending on the way of surgery completion. Patients in group I (n=27 underwent only skin suturing after the surgery, in group II –laporostoma was formed with VAC in the abdominal cavity. We have evaluated the level of microbe contamination and condition after wound surgery, intensity of adhesion process in the abdominal cavity, multiple organ failure after surgery. The use of laporostoma combined with VAC at different stages of generalized peritonitis treatment helps to achieve illness rigress, less number of planned saniations of abdominal cavity. Even after the first use of VAC, quicker clearance of operation wound and appearance of new granulation tis¬sues occurred. In group II in secondary saniation the frequency of fixing of abdominal cavity is developing 31,9% higher (p<0,05 and in the third saniation the use of VAC therapy resulted in growing number of patients with frozen abdomen.

    Cerebrospinal fluid (CSF) leak is the most commonly encountered perioperative complication in transsphenoidal surgery for pituitary lesions. Direct closure with a combination of autologous fat, local bone, and/or synthetic grafts remains the standard of care for leaks encountered at the time of surgery as well as postoperatively. The development of the vascularized nasoseptal flap as a closure technique has increased the surgeon’s capacity to correct even larger openings in the dura of the se...

  13. Abdominal Aortic Dissection with Acute Mesenteric Ischemia in a Patient with Marfan Syndrome

    2006-07-01

    Full Text Available Marfan syndrome is an autosomal dominant inherited disorder of connective tissue, with various complications manifested primarily in the cardiovascular system. It potentially leads to aortic dissection and rupture, these being the major causes of death. We report a patient who complained of acute abdominal pain, which presented as acute mesenteric ischemia combined with abdominal aortic dissection. Echocardiography showed enlargement of the aortic root and mitral valve prolapse. Abdominal computed tomography scan revealed acute mesenteric ischemia due to abdominal aortic dissection. Finally, the patient underwent surgery of aortic root replacement and had a successful outcome. Therefore, we suggest that for optimal risk assessment and monitoring of patients with Marfan syndrome, both aortic stiffness and the diameter of the superior mesenteric vein compared with that of the superior mesenteric artery are useful screening methods to detect acute mesenteric ischemia secondary to abdominal aortic dissection. Early diagnosis and early treatment can decrease the high mortality rate of patients with Marfan syndrome.

    Full Text Available Desmoid tumors (also called desmoids fibromatosis are rare slow growing benign and musculoaponeurotic tumors. Although these tumors have a propensity to invade surrounding tissues, they are not malignant. These tumors are associated with women of fertile age, especially during and after pregnancy. We report a young female patient with a giant desmoid tumor of the anterior abdominal wall who underwent primary resection. The patient had no history of an earlier abdominal surgery. Preoperative evaluation included abdominal ultrasound, computed tomography, and magnetic resonance imaging. The histology revealed a desmoid tumor. Primary surgical resection with immediate reconstruction of abdominal defect is the best management of this rarity. To the best of our knowledge and PubMed search, this is the first case ever reported in the medical literature of such a giant desmoid tumor arising from anterior abdominal wall weighing 6.5 kg treated surgically with successful outcome.

    To evaluate whether preoperative inspiratory muscle training is effective in preventing postoperative pulmonary complications and reducing length of hospital stay in people undergoing cardiothoracic or upper abdominal surgery. Medline, CINAHL, AMED, PsychINFO, Scopus, PEDro, and the Cochrane Library. A systematic review and meta analysis of randomized controlled trials (or quasi-randomized controlled trials) investigating a form of preoperative inspiratory muscle training, compared with sham or no inspiratory muscle training. Participants were adults (16 years and over) awaiting elective open cardiac, thoracic, or upper abdominal surgery. Methodological quality was assessed using the PEDro scale. Eight studies involving 295 participants were eligible for inclusion. The trained group had significantly higher maximal inspiratory pressure at the end of the preoperative training period (mean difference: 15 cm H2O, 95% confidence interval (CI): 9 to 21). This benefit was maintained through the early postoperative period, when lung function also recovered significantly more quickly in the trained group. Inspiratory muscle training also substantially reduced postoperative pulmonary complications (relative risk 0.48, 95% CI 0.26 to 0.89). Although not statistically significant, length of hospital stay also tended to favour the trained group. There were no statistically significant differences between the groups for the remaining outcomes. Participant satisfaction with inspiratory muscle training was high. Preoperative inspiratory muscle training significantly improves respiratory (muscle) function in the early postoperative period, halving the risk of pulmonary complications. The training does not increase length of stay, but more data are required to confirm whether it reduces length of stay. © The Author(s) 2014.

    Full Text Available Background: This study was designed to evaluate the postoperative analgesic efficacy of levobupivacaine (L alone and its combination with clonidine (C or dexmedetomidine (D in wound infiltration technique for abdominal surgeries. Materials and Methods: After ethical committee approval, a double-blind randomized controlled study was conducted on 90 patients (power of study 80%, physical status American Society of Anesthesiologists Grade I and II, aged 18–60 years scheduled for abdominal surgeries over 1 year duration. A standard general anesthetic technique was used. Patients were randomly allocated into three groups, by computer-generated random number table. Patients received wound infiltration during wound closure. Group L received 29 ml of 0.25% levobupivacaine plus 1 ml 0.9% normal saline, Group LC received 29 ml of 0.25% levobupivacaine with 1 ml (3 mcg/kg clonidine, and Group LD received 29 ml of 0.25% levobupivacaine with 1 ml (2 mcg/kg dexmedetomidine. Postoperative rescue analgesia was provided with injection tramadol. Statistical analysis for duration of analgesia was determined by one-way analysis of variance and side effects by Chi-square test. Results: The total duration of analgesia in LD group was 23.4 h, when compared to LC group 20.9 h and L group 11.65 h (P = 0.0001 with excellent to good quality of analgesia in adjuvant group (P < 0.001 and incidence of minimal side effects such as sedation, nausea, and vomiting. Conclusion: Clonidine and dexmedetomidine were the effective adjuvants to levobupivacaine for single shot wound infiltration analgesic technique; however, dexmedetomidine was found to be superior to clonidine.

  19. COMPARISON OF ROPIVACAINE (0.75% AND BUPIVACAINE (0.5% FOR EPIDURAL ANAESTHESIA IN PATIENTS POSTED FOR ELECTIVE LOWER ABDOMINAL AND EXTREMITY SURGERY

    Full Text Available Regional anaesthesia is becoming one of the most useful and versatile procedures in modern anesthesiology. Bupivacaine is a long acting amide local anaesthetic which is widely used since years, but it is associated with a many side effects like Central Nervous System (CNS toxicity and cardio toxicity. Ropivacaine is a newly introduced long acting amide local anaesthetic drug in India which has been developed as a possible alternative to Bupivacaine. It has a lower lipophilicity than bupivacaine and hence associated with a decreased potential f or CNS and cardiotoxicity. AIMS : The aim of the study was to compare the time of onset of sensory block and duration of sensory and motor blockade, duration of analgesia of epidural anaesthesia produced by bupivacaine 0.5% and ropivacaine 0.75% for lower a bdominal & limb surgery. METHODS : A prospective randomised study 60 patients, aged between 18 - 60 years, ASA 1 and 2, undergoing various lower abdominal & limb surgeries were randomly allocated to 2 groups of 30 each. Group B received 15ml of 0.5% bupivacai ne and group R received 15 ml of 0.75% bupivacaine epidurally. The time of onset of sensory, intensity of motor block, duration of sensory and motor block and hemodynamic changes were assessed. RESULTS : The time of onset and duration of sensory block was comparable for both the drugs. Bupivacaine 0.5% produced more intensity and longer duration of motor block than ropivacaine 0.75%. Both the drugs were comparable with respect to hemodynamic changes. CONC LUSION : Epidural ropivacaine 0.75% can be safely used as a possible alternative to bupivacaine 0.5% in lower abdominal and extremity procedures

    Capnometry detects hypoventilation earlier than pulse oximetry while supplemental oxygen is being administered. We compared the end-tidal CO 2 (P ETCO 2 ) measured using a newly developed oxygen nasal cannula with a CO 2 -sampling port and the P aCO 2 in extubated subjects after abdominal surgery. We also investigated whether the difference between P aCO 2 and P ETCO 2 is affected by resting, by spontaneous breathing with the mouth consciously closed, and by deep breathing with the mouth closed. Adult post-abdominal surgery subjects admitted to the ICU were enrolled. After extubation, oxygen was supplied at 4 L/min using a capnometry-type oxygen cannula. The breathing frequency, P ETCO 2 , and P aCO 2 were measured after 30 min of oxygen supplementation. P ETCO 2 was continuously measured during rest, during breathing with the mouth consciously closed, and during deep breathing with the mouth closed. The difference between P ETCO 2 and P aCO 2 during various breathing patterns was analyzed using the Bland-Altman method. Twenty subjects were included. The bias ± SD (limits of agreement) for breathing frequency measured by capnometry compared with those obtained by direct measurement was 0.4 ± 3.6 (-6.7 to 7.4). In P ETCO 2 compared with P aCO 2 , the biases (limits of agreement) were 14.8 ± 8.2 (-1.3 to 30.9) at rest, 10.2 ± 6.4 (-2.3 to 22.7) with the mouth closed, and 7.7 ± 5.6 (-3.2 to 18.6) for deep breathing with the mouth closed. P ETCO 2 determined using the capnometry device yielded unreliable and widely ranging values under various breathing patterns. However, deep breathing with the mouth closed decreased the difference between P ETCO 2 and P aCO 2 , as compared with other breathing patterns. P ETCO 2 measurements under deep breathing with mouth closed with a capnometry-type oxygen cannula improved the prediction of the absolute value of P aCO 2 in extubated post-abdominal surgical subjects without respiratory dysfunction.

    2007-01-01

    Purpose: To evaluate the effect of abdominal surgery on the volume effects of small-bowel toxicity during whole-pelvic irradiation in patients with gynecologic malignancies. Methods and Materials: From May 2003 through November 2006, 80 gynecologic patients without (Group I) or with (Group II) prior abdominal surgery were analyzed. We used a computed tomography (CT) planning system to measure the small-bowel volume and dosimetry. We acquired the range of small-bowel volume in 10% (V10) to 100% (V100) of dose, at 10% intervals. The onset and grade of diarrhea during whole-pelvic irradiation were recorded as small-bowel toxicity up to 39.6 Gy in 22 fractions. Results: The volume effect of Grade 2-3 diarrhea existed from V10 to V100 in Group I patients and from V60 to V100 in Group II patients on univariate analyses. The V40 of Group I and the V100 of Group II achieved most statistical significance. The mean V40 was 281 ± 27 cm 3 and 489 ± 34 cm 3 (p 3 and 132 ± 19 cm 3 (p = 0.003). Multivariate analyses revealed that V40 (p = 0.001) and V100 (p = 0.027) were independent factors for the development of Grade 2-3 diarrhea in Groups I and II, respectively. Conclusions: Gynecologic patients without and with abdominal surgery have different volume effects on small-bowel toxicity during whole-pelvic irradiation. Low-dose volume can be used as a predictive index of Grade 2 or greater diarrhea in patients without abdominal surgery. Full-dose volume is more important than low-dose volume for Grade 2 or greater diarrhea in patients with abdominal surgery

  6. Nutritional risk in major abdominal surgery: NURIMAS Liver (DRKS00010923 – protocol of a prospective observational trial to evaluate the prognostic value of different nutritional scores in hepatic surgery

    Directory of Open Access Journals (Sweden)

    Pascal Probst

    Full Text Available Background: Malnutrition is commonly known as a risk factor in surgical procedures. The nutritional status seems particularly relevant to the clinical outcome of patients undergoing hepatic resection. Thus, identifying affected individuals and taking preventive therapeutic actions before surgery is an important task. However, there are only very few studies, that investigate which existing nutritional assessment score (NAS is suited best to predict the postoperative outcome in liver surgery. Objective: Nutritional Risk in Major Abdominal Surgery (NURIMAS Liver is a prospective observational trial that analyses the predictive value of 12 different NAS for postoperative morbidity and mortality after liver resection. Methods: After admission to the surgical department of the University Hospital in Heidelberg or the municipal hospital of Karlsruhe, all patients scheduled for elective liver resection will be screened for eligibility. Participants will fill in a questionnaire and undergo a physical examination in order to evaluate nutritional status according to Nutritional Risk Index, Nutritional Risk Screening Score, Subjective Global Assessment, Malnutrition Universal Screening Tool, Mini Nutritional Assessment, Short Nutritional Assessment Questionnaire, Imperial Nutritional Screening System, Imperial Nutritional Screening System II, Nutritional Risk Classification and the ESPEN malnutrition criteria. Postoperative morbidity and mortality will be tracked prospectively throughout the postoperative course. The association of malnutrition according to each score and occurrence of at least one major complication will be analysed using both chi-squared tests and a multivariable logistic regression analysis. Already established risk factors in liver surgery will be added as covariates. Discussion: NURIMAS Liver is a bicentric, prospective observational trial. The aim of this study is to investigate the predictive value of clinical nutritional assessment

    Invasive mechanical ventilation during general anaesthesia for surgery typically causes atelectasis and impairs postoperative lung function. We investigated the effect of intraoperative ventilation with high positive end-expiratory pressure (PEEP) and recruitment manoeuvres (RMs) on postoperative spirometry. This was a preplanned, single-centre substudy of an international multicentre randomised controlled trial, the PROVHILO trial. University hospital from November 2011 to January 2013. Nonobese patients scheduled for major abdominal surgery at a high risk of postoperative pulmonary complications (PPCs). Intraoperative low tidal volume ventilation with PEEP levels of 12 cmH2O and RM (the high PEEP group) or with PEEP levels of 2 cmH2O or less without RM (the low PEEP group). Time-weighted averages (TWAs) of the forced expiratory volume in 1 s (FEV1) and the forced vital capacity (FVC) up to postoperative day five. Thirty-one patients were allocated to the high PEEP group and 32 to the low PEEP group. No postoperative spirometry test results were available for 6 patients. In both groups, TWA of FEV1 and FVC until postoperative day five were lower than preoperative values. Postoperative spirometry test results were not different between the high and low PEEP group; Data are median [interquartile range], TWA FVC 1.8 [1.6 to 2.4] versus 1.7 [1.2 to 2.4] l (P = NS) and TWA FEV1 1.2 [1.1 to 2.5] versus 1.2 [0.9 to 1.9] l (P = NS). Patients who developed PPCs had lower FEV1 and FVC on postoperative day five; 1.1 [0.9 to 1.6] versus 1.6 [1.4 to 1.9] l (P = 0.001) and 1.6 [1.2 to 2.6] versus 2.3 [1.7 to 2.6] l (P = 0.036), respectively. Postoperative spirometry is not affected by PEEP and RM during intraoperative ventilation for open abdominal surgery in nonobese patients at a high risk of PPCs, but rather is associated with the development of PPCs.

    Full Text Available Endometriosis is a frequent benign disorder. Malignancy arising in extraovarian endometriosis is a rare event. A 49-year-old woman is presented with a large painful abdominal wall mass. She underwent a myomectomy, 20 years before, for uterus leiomyoma. Computed tomography suggested that this was a desmoid tumor and she underwent surgery. Histological examination showed a clear cell adenocarcinoma associated with endometriosis foci. Pelvic ultrasound, computed tomography, and endometrial curettage did not show any malignancy or endometriosis in the uterus and ovaries. Adjuvant chemotherapy was recommended, but the patient was lost to follow up. Six months later, she returned with a recurrence of the abdominal wall mass. She was given chemotherapy and then she was reoperated.

    A simultaneous case of abdominal aortic aneurysm and lung cancer occurs rarely in clinical practice (fewer than 1% of all cases treated). Treating patients with a simultaneous ruptured abdominal aortic aneurysm and inoperable lung cancer still arouses a great deal of controversy throughout the world. A ruptured abdominal aortic aneurysm poses immediate danger to the patient's life. Several authors express the opinion that in case of a ruptured abdominal aortic aneurysm and inoperative lung cancer life-saving surgery should not be imdertaken, and state that the doctor shoidd let the patient die with dignity. In the following article we present the case of an 84-year-old patient who, having been diagnosed earlier with an inoperative lung tumor, underwent surgery because of a ruptured abdominal aortic aneurysm. We also present a review of literature concerning this issue and discusses its ethical and legal aspects. (authors)

    Full Text Available CONTEXTO: O tratamento cirúrgico convencional do aneurisma da aorta abdominal (AAA infra-renal pode resultar em complicações graves. A fim de otimizar os resultados na evolução do tratamento, é importante que sejam identificados os pacientes predispostos a determinadas complicações e instituídas condutas preventivas. OBJETIVOS: Avaliar a taxa de mortalidade operatória precoce, analisar as complicações pós-operatórias e identificar os fatores de risco relacionados com a morbimortalidade. MÉTODO: Foram analisados 134 pacientes com AAA infra-renal submetidos a correção cirúrgica eletiva no período de fevereiro de 2001 a dezembro de 2005. RESULTADOS: A taxa de mortalidade foi de 5,2%, sendo secundária principalmente a infarto agudo de miocárdio (IAM e isquemia mesentérica. As complicações cardíacas foram as mais freqüentes, seguidas das pulmonares e renais. A presença de diabetes melito (DM, insuficiência cardíaca congestiva (ICC, insuficiência coronariana (ICO e cintilografia miocárdica positiva para isquemia estiveram associadas às complicações cardíacas. A idade avançada, a doença pulmonar obstrutiva crônica (DPOC e a capacidade vital forçada reduzida aumentaram os riscos de atelectasia e pneumonia. História de nefropatia, tempo de pinçamento aórtico prolongado e níveis de uréia elevados aumentaram os riscos de insuficiência respiratória aguda (IRA. A isquemia dos membros inferiores esteve associada ao tabagismo e à idade avançada, e a maior taxa de mortalidade, à presença de coronariopatia, tempos prolongados de pinçamento aórtico e de cirurgia. CONCLUSÃO: A taxa de morbimortalidade esteve compatível com a literatura nacional e internacional, sendo secundária às complicações cardíacas, respiratórias e renais. Os fatores de risco identificados no pré e transoperatório estiveram relacionados com essas complicações.BACKGROUND: Conventional surgical treatment of infrarenal abdominal

    Full Text Available BACKGROUND: There is currently no consensus on the indication and benefits of breathing exercises for the prevention of postoperative pulmonary complications PPCs and for the recovery of pulmonary mechanics. OBJECTIVE: To undertake a systematic review of randomized and quasi-randomized studies that assessed the effects of breathing exercises on the recovery of pulmonary function and prevention of PCCs after upper abdominal surgery UAS. METHOD: Search Strategy: We searched the Physiotherapy Evidence Database PEDro, Scientific Electronic Library Online SciELO, MEDLINE, and Cochrane Central Register of Controlled Trials. Selection Criteria: We included randomized controlled trials and quasi-randomized controlled trials on pre- and postoperative UAS patients, in which the primary intervention was breathing exercises without the use of incentive inspirometers. Data Collection and Analysis: The methodological quality of the studies was rated according to the PEDro scale. Data on maximal respiratory pressures MIP and MEP, spirometry, diaphragm mobility, and postoperative complications were extracted and analyzed. Data were pooled in fixed-effect meta-analysis whenever possible. RESULTS: Six studies were used for analysis. Two meta-analyses including 66 participants each showed that, on the first day post-operative, the breathing exercises were likely to have induced MEP and MIP improvement treatment effects of 11.44 mmH2O (95%CI 0.88 to 22 and 11.78 mmH2O (95%CI 2.47 to 21.09, respectively. CONCLUSION: Breathing exercises are likely to have a beneficial effect on respiratory muscle strength in patients submitted to UAS, however the lack of good quality studies hinders a clear conclusion on the subject.

    This double-blind randomised controlled trial investigated whether normal saline or a balanced crystalloid has distinct effects on vasopressor use in patients undergoing major abdominal surgery. Patients received either normal saline 0.9% or an acetate-buffered crystalloid for intraoperative volume replacement in a goal-directed fashion. The primary outcome was need for vasopressors; the secondary outcomes were the total dose of catecholamines, total perioperative fluid, and unplanned intensive care admissions. This study was terminated early for safety reasons. A total of 60 out of the planned 240 patients were randomized. Thirty patients received normal saline and 30 patients received the balanced crystalloid, with a total volume of 3427 (2732-4130) ml and 3144 (1673-4926), respectively. The normal-saline group developed hyperchloraemic metabolic acidosis. More patients needed vasopressors for circulatory support in the normal-saline group compared with the buffered crystalloid group (97% vs 67%, respectively; P=0.033). The median weight and anaesthesia duration-adjusted dose of norepinephrine were 0.11 (0.00-0.45) ng kg -1  min -1 and 0.00 (0.00-0.00) kg -1  min -1 in the normal-saline and balanced-crystalloid groups, respectively (P=0.003). Cox regression revealed that the need for vasopressors was related to a high volume of administered fluid, normal-saline resuscitation, and lower mean arterial blood pressure. There was no difference between the groups in total perioperative fluid and unplanned intensive-care-unit admissions. Between-group differences in the duration of anaesthesia did not influence the necessity for a vasopressor. Compared with patients receiving a balanced crystalloid, normal saline in patients undergoing major abdominal surgery was associated with an increased need for vasopressor support. This should be interpreted in view of the large volume of fluid resuscitation and the small sample size because of the preliminary termination of

    To investigate whether the inclusion of deep breathing exercises in physiotherapy-directed early mobilisation confers any additional benefit in reducing postoperative pulmonary complications (PPCs) when patients are treated once daily after elective open upper abdominal surgery. This study also compared postoperative outcomes following early and delayed mobilisation. Cluster randomised controlled trial. Single-centre study in a teaching hospital. Eighty-six high-risk patients undergoing elective open upper abdominal surgery. Three groups: early mobilisation (Group A), early mobilisation plus breathing exercises (Group B), and delayed mobilisation (mobilised from third postoperative day) plus breathing exercises (Group C). PPCs and postoperative outcomes [number of days until discharge from physiotherapy, physiotherapy input and length of stay (LOS)]. There was no significant difference in PPCs between Groups A and B. The LOS for Group A {mean 10.7 [standard deviation (SD) 5.0] days} was significantly shorter than the LOS for Groups B [mean 16.7 (SD 9.7) days] and C [mean 15.2 (SD 9.8) days; P=0.036]. The greatest difference was between Groups A and B (mean difference -5.93, 95% confidence interval -10.22 to -1.65; P=0.008). Group C had fewer smokers (26%) and patients with chronic obstructive pulmonary disease (0%) compared with Group B (53% and 14%, respectively). This may have led to fewer PPCs in Group C, but the difference was not significant. Despite Group C having fewer PPCs and less physiotherapy input, the number of days until discharge from physiotherapy and LOS were similar to Group B. The addition of deep breathing exercises to physiotherapy-directed early mobilisation did not further reduce PPCs compared with mobility alone. PPCs can be reduced with once-daily physiotherapy if the patients are mobilised to a moderate level of exertion. Delayed mobilisation tended to increase physiotherapy input and the number of days until discharge from physiotherapy

    Previous studies have demonstrated that amino acid infusions exert enhanced thermogenic effects during general anesthesia. This study was conducted to investigate whether amino acid infusions started after development of intraoperative core hypothermia can accelerate rewarming. Twenty-two patients scheduled for major abdominal surgery were included in this study. When tympanic temperature reached 35.5°C, patients were randomly assigned to receive amino acids (amino acid group; n = 11) or saline (saline group; n = 11). A continuous infusion of a mixture of 18 amino acids or saline was started at 200 ml h(-1). Tympanic, forearm, and digit temperatures were recorded. Forearm minus fingertip skin-surface temperature gradients (temperature gradient) were calculated. Postoperative shivering was also evaluated. Tympanic membrane temperature and temperature gradient were similar between the two groups at each time point during the study period. Temperature gradient at extubation in the amino acid group was significantly lower than in the saline group although tympanic temperature at extubation was similar between the two groups. Postoperative shivering score was significantly lower in the amino acid group than in the saline group. Amino acid infusions started after development of intraoperative core hypothermia failed to accelerate rewarming. However, amino acid infusions reduced the incidence of postoperative shivering. Use of amino acid infusions to reduce thermoregulatory vasoconstriction at emergence might contribute to a decrease in the development of postoperative shivering.

    Full Text Available We report on 4 cases of abdominal compartment syndrome complicated by acute renal failure that were promptly reversed by different abdominal decompression methods. Case 1: A 57-year-old obese woman in the post-operative period after giant incisional hernia correction with an intra-abdominal pressure of 24 mm Hg. She was sedated and curarized, and the intra-abdominal pressure fell to 15 mm Hg. Case 2: A 73-year-old woman with acute inflammatory abdomen was undergoing exploratory laparotomy when a hypertensive pneumoperitoneum was noticed. During the surgery, enhancement of urinary output was observed. Case 3: An 18-year-old man who underwent hepatectomy and developed coagulopathy and hepatic bleeding that required abdominal packing, developed oliguria with a transvesical intra-abdominal pressure of 22 mm Hg. During reoperation, the compresses were removed with a prompt improvement in urinary flow. Case 4: A 46-year-old man with hepatic cirrhosis was admitted after incisional hernia repair with intra-abdominal pressure of 16 mm Hg. After paracentesis, the intra-abdominal pressure fell to 11 mm Hg.

    We have studied the effect of continuous extradural analgesia with bupivacaine and morphine, initiated before or after colonic surgery, in a double-blind, randomized study. Thirty-two patients were allocated randomly to receive an identical extradural block initiated 40 min before surgical incision...... (n = 16) or at closure of the surgical wound (n = 16). The extradural regimen consisted of a bolus of 7 ml of plain bupivacaine 7.5 mg ml-1 plus morphine 2 mg and continuous extradural infusion of a mixture of bupivacaine 7.5 mg ml-1 plus morphine 0.05 mg ml-1, 4 ml h-1 for 2 h, followed...... by a continuous extradural infusion of a mixture of bupivacaine 2.5 mg ml-1 plus morphine 0.05 mg ml-1, 4 ml h-1, continued for 72 h a
