One of the key challenges in perioperative care is to reduce postoperative morbidity and mortality. Patients who develop postoperative morbidity but survive to leave hospital have often reduced functional independence and long-term survival. Mechanical ventilation provides a specific example that may help us to shift thinking from treatment to prevention of postoperative complications. Mechanical ventilation in patients undergoing surgery has long been considered only as a modality to ensure gas exchange while allowing maintenance of anesthesia with delivery of inhaled anesthetics. Evidence is accumulating, however, suggesting an association between intraoperative mechanical ventilation strategy and postoperative pulmonary function and clinical outcome in patients undergoing abdominal surgery. Non-protective ventilator settings, especially high tidal volume (VT) (>10-12mL/kg) and the use of very low level of positive end-expiratory pressure (PEEP) (PEEPventilator-associated lung injury in patients with healthy lungs. Stimulated by previous findings in patients with acute respiratory distress syndrome, the use of lower tidal volume ventilation is becoming increasingly more common in the operating room. However, lowering tidal volume, though important, is only part of the overall multifaceted approach of lung protective mechanical ventilation. In this review, we aimed at providing the most recent and relevant clinical evidence regarding the use of mechanical ventilation in patients undergoing abdominal surgery.

To understand statewide variation in preoperative cardiology consultation prior to major vascular surgery and to determine whether consultation was associated with differences in perioperative myocardial infarction (poMI). Medical consultation prior to major vascular surgery is obtained to reduce perioperative risk. Despite perceived benefit of preoperative consultation, evidence is lacking specifically for major vascular surgery on the effect of preoperative cardiac consultation. Patient and clinical data were obtained from a statewide vascular surgery registry between January 2012 and December 2014. Patients were risk stratified by revised cardiac risk index category and compared poMI between patients who did or did not receive a preoperative cardiology consultation. We then used logistic regression analysis to compare the rate of poMI across hospitals grouped into quartiles by rate of preoperative cardiology consultation. Our study population comprised 5191 patients undergoing open peripheral arterial bypass (n = 3037), open abdominal aortic aneurysm repair (n = 332), or endovascular aneurysm repair (n = 1822) at 29 hospitals. At the patient level, after risk-stratification by revised cardiac risk index category, there was no association between cardiac consultation and poMI. At the hospital level, preoperative cardiac consultation varied substantially between hospitals (6.9%-87.5%, P 66%) had a reduction in poMI (OR, 0.52; confidence interval: 0.28-0.98; P cardiology consultation for vascular surgery varies greatly between institutions, and does not appear to impact poMI at the patient level. However, reduction of poMI was noted at the hospitals with the highest rate of preoperative cardiology consultation as well as a variety of medical services, suggesting that other hospital culture effects play a role.

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

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.

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.

Full Text Available Purpose. Transversus abdominis plane (TAP blocks have been shown to reduce pain and opioid requirements after abdominal surgery. The aim of the present case series was to demonstrate the use of TAP catheter injections of bupivacaine after major abdominal surgery. Methods. Fifteen patients scheduled for open colonic resection surgery were included. After induction of anesthesia, bilateral TAP catheters were placed, and all patients received a bolus dose of 20 mL bupivacaine 2.5 mg/mL with epinephrine 5 μg/mL through each catheter. Additional bolus doses were injected bilaterally 12, 24, and 36 hrs after the first injections. Supplemental pain treatment consisted of paracetamol, ibuprofen, and gabapentin. Intravenous morphine was used as rescue analgesic. Postoperative pain was rated on a numeric rating scale (NRS, 0–10 at regular predefined intervals after surgery, and consumption of intravenous morphine was recorded. Results. The TAP catheters were placed without any technical difficulties. NRS scores were ≤3 at rest and ≤5 during cough at 4, 8, 12, 18, 24, and 36 hrs after surgery. Cumulative consumption of intravenous morphine was 28 (23–48 mg (median, IQR within the first 48 postoperative hours. Conclusion. TAP catheter bolus injections can be used to prolong analgesia after major abdominal surgery.

Since atherosclerotic heart disease results in more than half of the perioperative deaths that follow abdominal aortic surgery, a prospective protocol was designed for preoperative evaluation and intraoperative hemodynamic monitoring. Twenty men who were prepared to undergo elective operation for aortoiliac occlusive disease (12 patients) and abdominal aortic aneurysm (eight patients) were evaluated with a cardiac scan and right heart catheterization. The night prior to operation, each patient received volume loading with crystalloid based upon ventricular performance curves. At the time of the operation, all patients were anesthetized with narcotics and nitrous oxide, and hemodynamic parameters were recorded throughout the operation. Aortic crossclamping resulted in a marked depression in CI in all patients. CI remained depressed after unclamping in the majority of patients. There were two perioperative deaths, both from myocardial infarction or failure. Both patients had ejection fractions less than 30% and initial CIs less than 2 L/M2, while the survivors' mean ejection fraction was 63% +/- 1 and their mean CI was 3.2 L/M2 +/- 0.6. The authors conclude that preoperative evaluation of ejection fraction can select those patients at a high risk of cardiac death from abdominal aortic operation. These patients should receive intensive preoperative monitoring with enhancement of ventricular performance

We describe FDG-PET/CT findings of postoperative fat necrosis in patients following abdominal surgery, and evaluate their changes in size and FDG uptake over time. FDG-PET/CT scans from January 2007-January 2016 containing the term 'fat necrosis' were reviewed. Lesions meeting radiological criteria of fat necrosis in patients with prior abdominal surgery were included. Forty-four patients, 30 males, mean age 68.4 ± 11.0 years. Surgeries: laparotomy (n=37; 84.1 %), laparoscopy (n=3; 6.8 %), unknown (n=4; 9.1 %). CTs of all lesions included hyperdense well-defined rims surrounding a heterogeneous fatty core. Sites: peritoneum (n=34; 77 %), omental fat (n=19; 43 %), subcutaneous fat (n=8; 18 %), retroperitoneum (n=2; 5 %). Mean lesion long axis: 33.6±24.9 mm (range: 13.0-140.0). Mean SUVmax: 2.6±1.1 (range: 0.6-5.1). On serial CTs (n=34), lesions decreased in size (p=0.022). Serial FDG-PET/CT (n=24) showed no significant change in FDG-avidity (p=0.110). Mean SUVmax did not correlate with time from surgery (p=0.558) or lesion size (p=0.259). Postsurgical fat necrosis demonstrated characteristic CT features and may demonstrate increased FDG uptake. However, follow-up of subsequent imaging scans showed no increases in size or FDG-avidity. Awareness of this entity is important to avoid misinterpretation of findings as recurrent cancer. • Postsurgical fat necrosis may mimic cancer in FDG-PET/CT. • Follow-up of fat necrosis showed no increase in FDG intensity. • CT follow-up showed a decrease in lesion size. • FDG uptake did not correlate with time lapsed from surgery.

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.

The greater omentum is the largest peritoneal fold and can be the origin of primary pathologic conditions, as well as a boundary and conduit for disease processes. Most diseases involving the omentum manifest with nonspecific and overlapping features on computed tomography (CT). In particular, varying benign disease processes of traumatic, inflammatory, vascular, or systemic origin can occur in the omentum during the follow-up period after surgery for intra-abdominal malignancy. It can be challenging for radiologists due to various spectrum of CT findings. Thus, we reviewed the CT findings of various benign omental lesions after surgery for intra-abdominal malignancy.

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.

Abdominal aortic surgery is a form of major vascular surgery, which traditionally involves long hospital stays and significant postoperative morbidity. Experiences with transit ileus are often encountered after the aortic surgery. Thus traditional postoperative care involves delayed oral feeding until the patients regain their normal bowel activities. This report examines the feasibility of early postoperative feeding after abdominal aortic aneurysm (AAA) open-repair. From May 2002 through May 2003, 10 consecutive patients with infrarenal AAA who underwent elective surgical open-repair by the same surgeon in our department were reviewed. All of them had been operated upon and cared for according to the early feeding postoperative care protocol, which comprised of adjuvant epidural anesthesia, postoperative patient controlled analgesia, early postoperative feeding and early rehabilitation. The postoperative recovery and length of hospital stay were reviewed and analyzed. All patients were able to sip water within 1 day postoperatively without trouble (Average; 12.4 hours postoperatively). All but one patient was put on regular diet within 3 days postoperatively (Average; 2.2 days postoperatively). The average postoperative length of stay in hospital was 5.8 days. No patient died or had major morbidity. Early postoperative feeding after open repair of abdominal aorta is safe and feasible. The postoperative recovery could be improved and the length of stay reduced by simply using adjuvant epidural anesthesia during surgery, postoperative epidural patient-controlled analgesia, early feeding, early ambulation, and early rehabilitation. The initial success of our postoperative recovery program of aortic repair was demonstrated.

With the increasing diffusion of percutaneous interventions (PCI), surgeons are often faced with the problem of operating on patients under dual antiplatelet treatment. Replacing dual antiplatelet regiment with low molecular weight heparin may expose to the abrupt thrombosis of coronary stent and massive myocardial infarction. The purpose of this study was to test the hypothesis that abdominal operations can be safely performed under dual antiplatelet treatment. Eleven patients underwent 5 colectomies, 3 nefrectomies, 2 gastrectomies and 1 hysterectomy under aspirin and plavix without any significant perioperative hemorrhage. These preliminary results show that abdominal operations can be safely performed under dual antiplatelet regimen. Abdominal surgery, Dual antiplatelet treatment.

Abdominal compartment syndrome following abdominoplasty: A case report and review

Full Text Available Abdominoplasty is among the most commonly performed aesthetic procedures in plastic surgery. Despite high complication rate, abdominal contouring procedures are expected to rise in popularity with the advent of bariatric surgery. Patients with a history of gastric bypass surgery have an elevated incidence of small bowel obstruction from internal herniation, which is associated with non-specific upper abdominal pain, nausea, and a decrease in appetite. Internal hernias, when subjected to elevated intra-abdominal pressures, have a high-risk of developing ischemic bowel. We present a case report of patient with previous laparoscopic Roux-en-y gastric bypass who developed acute ischemic bowel leading to abdominal compartment syndrome following abdominoplasty. To the best of our knowledge, this is the first reported case in the literature. We herein emphasise on the subtle symptoms and signs that warrant further investigations in prospective patients for an abdominal contouring procedure with a prior history of gastric bypass surgery.

2003-01-01

The purpose of our study is to demonstrate the value of CT in the emergency department (ED) for patients with non-traumatic abdominal pain. Between August 1998 and April 1999, 536 consecutive patients with non-traumatic abdominal pain were entered into our study. Using a computer order entry system, physicians were asked to identify: (a) their most likely diagnosis; (b) their level of certainty in their diagnosis; (c) if they thought CT would be normal or abnormal; (d) their treatment plan (prior to knowledge of the CT results); and (e) their role in deciding to order CT. This information was correlated with each patient's post-CT diagnosis and subsequent management. Pre- and post-CT diagnoses were concordant in 200 of 536 (37%) patients. The physicians' certainty in the accuracy of their pre-CT diagnosis was less than high in 88% of patients. Prior to CT, the management plan included hospital admission for 402 patients. Following CT, only 312 patients were actually admitted; thus, the net impact of performing CT was to obviate the need for hospital admission in 90 of 536 (17%) of patients with abdominal pain. Prior to CT, 67 of 536 (13%) of all patients would have undergone immediate surgery; however, following CT only 25 (5%) actually required immediate surgery. Among patients with the four most common pre-CT diagnoses (appendicitis, abscess, diverticulitis, and urinary tract stones) CT had the greatest impact on hospital admission and surgical management for patients with suspected appendicitis. For patients with suspected appendicitis, CT reduced the hospital admission rate in 28% (26 of 91) of patients and changed the surgical management in 40% (39 of 91) of patients. Our study demonstrates the advantage of performing abdominal CT in the ED for patients with non-traumatic abdominal pain. (orig.)

Full Text Available Adriana Toro, Maurizio Mannino, Giulio Reale, Isidoro Di CarloDepartment of Surgical Sciences, Organ Transplantation, and Advanced Technologies, University of Catania, Cannizzaro Hospital, Catania, ItalyAbstract: The success of any surgical procedure is based on adequate hemostasis. Many different biomaterial products can be used to achieve that aim. The products that can be used during surgery may be classified as topical hemostats, sealants, and adhesives. Hemostats can clot blood. Sealants can create sealing barriers. Adhesives bond tissue together. Collagen, gelatin, and cellulose are hemostat agents. TachoSil® is a development of TachoComb® and TachoComb® H. TachoComb is made with equine collagen, bovine thrombin, bovine aprotinin, and human fibrinogen. The clinical efficacy of TachoSil was shown firstly by a clinical study of hepatic surgery. In the study, TachoSil proved to be superior to argon beamer in obtaining effective and fast intraoperative hemostasis. Following the study, many applications in different fields of surgery have been reported in the literature. The use of TachoSil in open abdominal surgery and its relevant results have encouraged the use of TachoSil in laparoscopic surgery. Unfortunately, its use in laparoscopy has not become as popular as it is in open surgery, due to a lack of efficacious techniques. Immunologic reactions to compounds of TachoSil and the transmission of infectious diseases are two major risks concerning topical hemostasis. Even though the risk of severe immunologic reactions to bovine material is low, TachoSil has gradually replaced all bovine material with material of human origin and has therefore eliminated the associated risks of bovine material. TachoSil has a good satisfaction rate among surgeons and reduces both the operating time for patients and the time spent in intensive care units.Keywords: TachoSil, abdominal surgery, hemostasis

Frederiksen, Sven G; Ekelund, Mikael

2016-04-01

Gastric bypass (GBP) has been the most common surgical way to treat obesity and its comorbidities. Late abdominal pain may occur by gastro-jejunal ulcers, gallstones, internal herniation or, rarely, intussusception. In an area with more than 1000 GBPs performed yearly, three patients with primary small bowel volvulus causing abdominal pain and requiring emergency or semi-urgent surgery were identified. Patients' histories, radiology, and surgery performed are presented. Weight loss followed by mesenteric narrowing of the root and thus relative elongation may make rotation of the small bowel mesentery possible. Such a torsion might be an overlooked differential diagnosis in obscure abdominal pain after GBP.

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

A double-blinded randomized controlled study to compare discharge time and patient satisfaction between two groups of patients submitted to open surgeries for abdominal malignancies using segmental thoracic spinal or general anesthesia. Open surgeries for abdominal malignancy are usually done under general anesthesia, but many patients with major medical problems sometimes can't tolerate such anesthesia. Regional anesthesia namely segmental thoracic spinal anesthesia may be beneficial in such patients. A total of 60 patients classified according to American Society of Anesthesiology (ASA) as class II or III undergoing surgeries for abdominal malignancy, like colonic or gastric carcinoma, divided into two groups, 30 patients each. Group G, received general anesthesia, Group S received a segmental (T9-T10 injection) thoracic spinal anesthesia with intrathecal injection of 2 ml of hyperbaric bupivacaine 0.5% (10 mg) and 20 ug fentanyl citrate. Intraoperative monitoring, postoperative pain, complications, recovery time, and patient satisfaction at follow-up were compared between the two groups. Spinal anesthesia was performed easily in all 30 patients, although two patients complained of paraesthesiae, which responded to slight needle withdrawal. No patient required conversion to general anesthesia, six patients required midazolam for anxiety and six patients required phenylephrine and atropine for hypotension and bradycardia, recovery was uneventful and without sequelae. The two groups were comparable with respect to gender, age, weight, height, body mass index, ASA classification, preoperative oxygen saturation and preoperative respiratory rate and operative time. This preliminary study has shown that segmental thoracic spinal anesthesia can be used successfully and effectively for open surgeries for abdominal malignancies by experienced anesthetists. It showed shorter postanesthesia care unit stay, better postoperative pain relief and patient satisfaction than

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. First request to analgesia was significantly longer in the bupivacaine patients than in the placebo group (5.87±3.04 h vs.1.35±0.36; p<0.001.Meperidine consumption over 24h was 96.00 ±17.53 mg in the placebo group compared with 23.28 ±14.89 mg in the bupivacaine patients (p<0.001.Conclusion:A combination of intraperitoneal and incisional bupivacaine infiltration at the end of abdominal gynecologic surgeries reduces postoperative pain on awakening and for 6 hours after surgery, and provides significant opioidsparing analgesia for 24 h after gynecologic abdominal surgeries.

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

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.

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.

Chest physiotherapy with positive expiratory pressure breathing after abdominal and thoracic surgery: a systematic review.

Orman, J; Westerdahl, E

A variety of chest physiotherapy techniques are used following abdominal and thoracic surgery to prevent or reduce post-operative complications. Breathing techniques with a positive expiratory pressure (PEP) are used to increase airway pressure and improve pulmonary function. No systematic review of the effects of PEP in surgery patients has been performed previously. The purpose of this systematic review was to determine the effect of PEP breathing after an open upper abdominal or thoracic surgery. A literature search of randomised-controlled trials (RCT) was performed in five databases. The trials included were systematically reviewed by two independent observers and critically assessed for methodological quality. We selected six RCT evaluating the PEP technique performed with a mechanical device in spontaneously breathing adult patients after abdominal or thoracic surgery via thoracotomy. The methodological quality score varied between 4 and 6 on the Physiotherapy Evidence Database score. The studies were published between 1979 and 1993. Only one of the included trials showed any positive effects of PEP compared to other breathing techniques. Today, there is scarce scientific evidence that PEP treatment is better than other physiotherapy breathing techniques in patients undergoing abdominal or thoracic surgery. There is a lack of studies investigating the effect of PEP over placebo or no physiotherapy treatment.

The caudal epidural block is one of the most commonly used regional anesthetic techniques in children. Administration of morphine via caudal injection enables analgesia, even for upper abdominal surgery. The thoracic paravertebral block has also been successfully used to treat perioperative pain during upper abdominal procedures in pediatric patients. In the current study, we compared the two regional techniques for upper abdominal surgery in infants to determine whether one of them was preferable to the other. Consecutive patients under 12 months of age who underwent upper abdominal surgery were retrospectively divided according to the chosen postoperative analgesia: Group C, caudal ropivacaine-morphine; Group P, paravertebral catheter. We analyzed the following outcomes: requirement for additional analgesics, pain scores, need for mechanical ventilation and oxygen dosage, postoperative blood pressure and heart rate, time to pass first stool, time until first full meal, and complications. Twenty-one consecutive patients were included: 10 in Group C and 11 in Group P. Median age at surgery was 80 (47.5-270.0) and 84.5 (34.3-287.5) days, respectively. No difference was found between the two groups in requirement for additional analgesics at 24 h after surgery (median 1 in Group C vs 1 in Group P, P = 0.288, 95% CI: -2 to 1). BOPS pain scores were only lower in Group P when compared to Group C at 24 h after surgery (median 1 vs 2, P = 0.041, 95% CI: -2 to 0). None of the patients had perioperative complications. In this small series, there was no significant difference between caudal ropivacaine-morphine and paravertebral catheter for postoperative care in infants undergoing upper abdominal surgery. Further prospective studies are needed to compare the efficacy and incidence of complications of caudal block and paravertebral catheter for postoperative analgesia. © 2017 John Wiley & Sons Ltd.

[Globalization: challenges in abdominal surgery for migrants and refugees].

Science.gov (United States)

Wilhelm, T J; Post, S

2018-03-01

The increasing number of refugees, migrants and international travelers influences the surgical spectrum of abdominal diseases. The aim of this review is to familiarize surgeons with specific diseases which are endemic in the patients' countries of origin and are likely to be diagnosed with increasing incidence in Germany. Low levels of hygiene in the countries of origin or refugee camps is associated with a high incidence of numerous infections, such as helminth infections, typhoid fever or amoebiasis, which if untreated can cause surgical emergencies. Historically, some of them were common in Germany but have been more or less eradicated because of the high socioeconomic standard. Echinococcosis and Chagas disease are frequently treated surgically while schistosomiasis can mimic intestinal cancer. Abdominal tuberculosis presents in a variety of abdominal pathologies and frequently causes diagnostic uncertainty. Sigmoid volvulus has a very low incidence among Europeans, but is one of the most common abdominal surgical conditions of adults in endemic countries. The number of patients who eventually undergo surgery for these conditions might be relatively low; however, surgeons must be aware of them and consider them as differential diagnoses in refugees and migrants with acute or chronic abdominal symptoms.

Right Lower Quadrant Abdominal Pain in a Patient with Prior Ventriculoperitoneal Shunting: Consider the Tip!

2012-01-01

Full Text Available Introduction. Ventriculoperitoneal (VP shunting is the treatment of choice for nonobstructive hydrocephalus. In patients with such a device, right lower quadrant abdominal pain can puzzle the surgeon, posing a differential diagnostic problem among appendicitis, nonsurgical colicky pain, and primary shunt catheter tip infection. Treatment is different in either case. Presentation of Case. We hereby present a case of a young woman with prior ventriculoperitoneal shunt positioning who presented to our department with right lower quadrant abdominal pain. The patient underwent a 24-hour observation including a neurosurgery consult in order to exclude acute appendicitis and VP shunt tip infection. Twenty four hours later, the patient’s symptomatology improved, and she was discharged with the diagnosis of atypical colicky abdominal pain seeking a gastroenterologist consult. Discussion. This case supports that when a patient with prior VP shunting presents with right lower quadrant abdominal pain, differential diagnosis can be tricky for the surgeon. Conclusion. Apart from acute appendicitis, primary or secondary VP catheter tip infection must be considered because the latter can be disastrous.

Interhospital transfer delays emergency abdominal surgery and prolongs stay.

Interhospital transfer of patients requiring emergency surgery is common practice. It has the potential to delay surgical intervention, increase rate of complications and thus length of hospital stay. A retrospective cohort study was conducted of adult patients who underwent emergency surgery for abdominal pain at a large metropolitan hospital in New South Wales (Hospital A) in 2013. The impact of interhospital transfer on time to surgical intervention, post-operative length of stay and overall length of stay was assessed. Of the 910 adult patients who underwent emergency surgery for abdominal pain at Hospital A in 2013, 31.9% (n = 290) were transferred by road ambulance from a local district hospital (Hospital B). The leading surgical procedures performed were appendicectomy (n = 299, 32.9%), cholecystectomy (n = 174, 19.1%), gastrointestinal endoscopy (n = 95, 10.4%), cystoscopy (n = 86, 9.5%), hernia repair (n = 45, 4.9%), salpingectomy (n = 19, 2.1%) and oversewing of perforated peptic ulcer (n = 13, 1.4%). Overall, interhospital transfer (n = 290, 31.9%) was associated with increases in mean time to surgical intervention (14.2 h, P < 0.001), post-operative length of stay (1.1 days, P = 0.001) and overall length of stay (1.6 days, P < 0.001). Delayed surgical intervention was observed across all procedure types except surgery for perforated peptic ulcer, where transferred patients underwent surgery within a comparable timeframe to direct admissions. Interhospital transfer delays surgical intervention and increases length of hospital stay. This mandates attention due to the implications for patient outcomes and added burden to the healthcare system. The system did, however, show capability to appropriately expedite surgery for acutely life-threatening cases. © 2016 Royal Australasian College of Surgeons.

Clinical utility and cost-effectiveness of carotid duplex examination prior to cardiac surgery have been questioned by the multidisciplinary committee creating the 2012 Appropriate Use Criteria for Peripheral Vascular Laboratory Testing. We report the clinical outcomes and postoperative neurologic symptoms in patients who underwent carotid duplex ultrasound prior to open heart surgery at a tertiary institution. Using the combined databases from our clinical vascular laboratory and the Society of Thoracic Surgery, a retrospective analysis of all patients who underwent carotid duplex ultrasound within 13 months prior to open heart surgery from March 2005 to March 2013 was performed. The outcomes between those who underwent carotid duplex scanning (group A) and those who did not (group B) were compared. Among 3233 patients in the cohort who underwent cardiac surgery, 515 (15.9%) patients underwent a carotid duplex ultrasound preoperatively, and 2718 patients did not (84.1%). Among the patients who underwent carotid screening vs no screening, there was no statistically significant difference in the risk factors of cerebrovascular disease (10.9% vs 12.7%; P = .26), prior stroke (8.2% vs 7.2%; P = .41), and prior transient ischemic attack (2.9% vs 3.3%; P = .24). For those undergoing isolated coronary artery bypass grafting (CABG), 306 (17.8%) of 1723 patients underwent preoperative carotid duplex ultrasound. Among patients who had carotid screening prior to CABG, the incidence of carotid disease was low: 249 (81.4%) had minimal or mild stenosis (duplex scanning and those who did not. Primary outcomes of patients who underwent open heart surgery also showed no difference in the perioperative mortality (5.1% vs 6.9%; P = .14) and stroke (2.6% vs 2.4%; P = .85) between patients undergoing preoperative duplex scanning and those who did not. Operative intervention of severe carotid stenosis prior to isolated CABG occurred in 2 of the 17 patients (11.8%) identified who

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.

Full Text Available Myocardial injury after noncardiac surgery (MINS is a newly proposed concept that is common among adults undergoing noncardiac surgery and associated with substantial mortality. We analyzed whether MINS was a risk factor for weaning failure in critical patients who underwent major abdominal surgery.This retrospective study was conducted in the Department of Critical Care Medicine of Peking University People's Hospital. The subjects were all critically ill patients who underwent major abdominal surgery between January 2011 and December 2013. Clinical and laboratory parameters during the perioperative period were investigated. Backward stepwise regression analysis was performed to evaluate MINS relative to the rate of weaning failure. Age, hypertension, chronic renal disease, left ventricular ejection fraction before surgery, Acute Physiologic and Chronic Health Evaluation II score, pleural effusion, pneumonia, acute kidney injury, duration of mechanical ventilation before weaning and the level of albumin after surgery were treated as independent variables.This study included 381 patients, of whom 274 were successfully weaned. MINS was observed in 42.0% of the patients. The MINS incidence was significantly higher in patients who failed to be weaned compared to patients who were successfully weaned (56.1% versus 36.5%; P<0.001. Independent predictive factors of weaning failure were MINS, age, lower left ventricular ejection fraction before surgery and lower serum albumin level after surgery. The MINS odds ratio was 4.098 (95% confidence interval, 1.07 to 15.6; P = 0.04. The patients who were successfully weaned had shorter hospital stay lengths and a higher survival rate than those who failed to be weaned.MINS is a risk factor for weaning failure from mechanical ventilation in critical patients who have undergone major abdominal surgery, independent of age, lower left ventricular ejection fraction before surgery and lower serum albumin levels after

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.

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.

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

Full Text Available Surgery in cirrhotic patients is associated with high morbidity and mortality related to portal hypertension and liver insufficiency. Therefore, preoperative portal decompression is a logical approach to facilitate abdominal surgery and hopefully to improve postoperative survival. The present study evaluated the clinical outcomes of 18 patients (mean age 58 years with cirrhosis (seven alcoholics and 11 nonalcoholics who underwent transjugular intrahepatic portosystemic shunt (TIPS placement before antrectomy (n=5, colectomy (n=10, small-bowel resection (n=1, pancreatectomy (n=1 and nephrectomy (n=1. TIPS was performed a mean (± SD of 72±21 days before surgery and induced a marked mean decrease in portohepatic gradient from 21.4±3.9 mmHg to 8.4±3.4 mmHg. Cirrhotic patients (n=17 who underwent elective abdominal surgery without preoperative TIPS placement were used as the control group. Both groups were matched for age, etiology of cirrhosis, indications for surgery, type of surgery and coagulation parameters. The mean Pugh score was significantly higher in the TIPS group (7.7 versus 6.2. No significant differences were observed for operative blood loss, postoperative complications, duration of hospitalization and one-month (83% versus 88% or one-year (54% versus 63% cumulative survival rate. Analysis using the Cox proportional hazards model showed that neither TIPS placement nor preoperative Pugh score were independent predictors for survival. The present study suggests that preoperative TIPS placement does not improve postoperative evolution after abdominal surgery in cirrhotic patients with good or moderately impaired liver function.

We previously described an endoscopic-assisted transvaginal mesh excision technique. This study compares surgical outcomes after transvaginal mesh excision vs endoscopic-assisted transvaginal mesh excision. In addition, we reviewed our postoperative outcomes with excision via laparotomy. This was an inclusive retrospective analysis of patients presenting to our institution from 1997 to 2006 for surgical management of vaginal erosion of permanent mesh after sacrocolpopexy. Three techniques were utilized: transvaginal, endoscopic-assisted transvaginal, and laparotomy. For the patients undergoing transvaginal excision, data recorded included number and type of excisions performed, number of prior excisions performed at outside facilities, intraoperative and postoperative complications (including blood transfusions, pelvic abscess, or bowel complications), use of postoperative antibiotics, persistent symptoms of vaginal bleeding and discharge at follow-up, and demographic characteristics. The intraoperative and postoperative complications and the postoperative symptoms were recorded for the laparotomy cases. Thirty-one patients underwent transvaginal mesh excision during this time period: 17 endoscopic-assisted transvaginal and 14 transvaginal without endoscope assistance. In addition, a total of 7 patients underwent abdominal excision via laparotomy. Comparison of the 2 vaginal methods revealed no difference in the demographics or success rate, with success defined as no symptoms at follow-up. Endoscopic-assisted transvaginal excision was successful in 7 of 17 patients and transvaginal without endoscopic assistance in 9 of 13 patients (1 patient excluded for lack of follow-up data) for a total vaginal success rate of 53.3%. No intraoperative and only minor postoperative complications occurred with either vaginal method. Three patients underwent 3 vaginal attempts to achieve complete symptom resolution. The average follow-up time for the entire vaginal group was 14

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

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.

Evaluation of the macula prior to cataract surgery.

2018-01-01

To describe recent evidence regarding methods of evaluation of retinal structure and function prior to cataract surgery. Studies in patients with cataract but no clinically detectable retinal disease have shown that routine use of optical coherence tomography (OCT) prior to cataract surgery can detect subtle macular disease, which may alter the course of treatment or lead to modification of consent. The routine use of OCT has been especially useful in patients being considered for advanced-technology intraocular lenses (IOLs) as subtle macular disease can be a contraindication to the use of these lenses. The cost-effectiveness of routine use of OCT prior to cataract surgery has not been studied. Other technologies that assess retinal function rather than structure, such as microperimetry and electroretinogram (ERG) need further study to determine whether they can predict retinal potential in cataract patients. There is growing evidence for the importance of more detailed retinal evaluation of cataract patients even with clinically normal exam. OCT has been the most established and studied method for retinal evaluation in cataract patients, but other technologies such as microperimetry and ERG are beginning to be studied.

Full Text Available An adequate mechanical colon preparation prior to abdominal surgery is mandatory in order to prevent infectious and mechanical complications after surgery. The standard strategies for mechanical bowel preparation are based in the use of oral solutions.Aim: To compare effectiveness, security and tolerance of two methods for mechanical bowel preparation (Fosfosoda® and Solución Evacuante Bohm®.Methodology: Descriptive study of the prospective cohort of patients admitted for surgery requiring previous bowel preparation in the Fundación Hospital Alcorcón (Madrid, between October 01 and June 02 Results: Within patients who received Fosfosoda® as preparative solution (24/47%, 66% did not experience associated symthomatology at all, but 5 (21% experienced vomiting. The bowel cleaning quality was classified as good or excellent in 92% of them according to nursing evaluation and as excellent in 70% according to surgeon evaluation. Due to an inadequate bowel cleaning 2 patients (8% required an enema administration prior to surgery. Within patients who were treated with Solución Evacuante Bohm® (27/53%, 57% experienced no associated symthoms, 2 of them (7,5% experienced vomiting, the bowel cleaning quality was classified as good/excellent in 85% by nurses and as excellent in 73% by surgeons.

Predictive value of C-reactive protein in critically ill patients after abdominal surgery

Directory of Open Access Journals (Sweden)

Frédéric Sapin

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.

Conclusion:. Surgical outcomes of bilateral reconstructions in patients with abdominal scars are generally comparable with ones in patients without prior surgery; however, some problems have been identified. These procedures might have some intraoperative considerations and often require increased operative times. Apart from the traditional preoperative computed tomography angiography, intraoperative imaging (e.g., fluorescence angiography may be advocated in patients with abdominal scars.

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.

Late Onset of CSF Rhinorrhea in a Postoperative Transsphenoidal Surgery Patient Following Robotic-Assisted Abdominal Hysterectomy

Directory of Open Access Journals (Sweden)

Justin T. Dowdy MD

2014-01-01

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.

The paper addresses the automated segmentation of multiple organs in upper abdominal CT data. We propose a framework of multi-organ segmentation which is adaptable to any imaging conditions without using intensity information in manually traced training data. The features of the framework are as follows: (1) the organ correlation graph (OCG) is introduced, which encodes the spatial correlations among organs inherent in human anatomy; (2) the patient-specific organ shape and location priors obtained using OCG enable the estimation of intensity priors from only target data and optionally a number of untraced CT data of the same imaging condition as the target data. The proposed methods were evaluated through segmentation of eight abdominal organs (liver, spleen, left and right kidney, pancreas, gallbladder, aorta, and inferior vena cava) from 86 CT data obtained by four imaging conditions at two hospitals. The performance was comparable to the state-of-the-art method using intensity priors constructed from manually traced data.

Background Single ventricle patients undergoing surgical reconstruction experience a high rate of brain injury; incidental findings on pre-operative brain scans may result in safety considerations involving hemorrhage extension during cardiopulmonary bypass that result in surgical postponement. Methods Single ventricle patients were studied with brain scans immediately preoperatively as part of a National Institute of Health study and were reviewed by neuroradiology immediately prior to cardiopulmonary bypass. Results One hundred and thirty four consecutive subjects recruited into the project were studied: 33 prior to stage I (3.7±1.8 days), 34 prior to bidirectional Glenn (5.8±3.5 months) and 67 prior to Fontan (3.3±1.1 years). Six (4.5%) surgeries were postponed because of concerning imaging findings on brain MRI; 2 prior to stage I, 3 prior to bidirectional Glenn and 1 prior to Fontan. Five were due to unexpected incidental findings of acute intracranial hemorrhage and one due to diffuse cerebellar cytotoxic edema; none who proceeded to surgery had these lesions. Prematurity as well as genetic syndromes were not present in any with postponed surgery. Four of 4 prior to bidirectional Glenn/Fontan with surgical delays had hypoplastic left heart syndrome compared with 44/97 who did not (P=0.048). After observation and follow up, all eventually had successful surgeries with bypass. Conclusion Preoperative brain MRI performed in children with single ventricles disclosed injuries in 4.5% leading to surgical delay; hemorrhagic lesions were most common and raised concerns for extension during surgery. The true risk of progression and need for delay of surgery due to heparinization associated with these lesions remains uncertain. PMID:25149046

Rafael Luis Sakai

Full Text Available CONTEXT AND OBJECTIVE: The significant relationship between upper abdominal surgery and early (perioperative pulmonary events was investigated among patients with preoperative pulmonary conditions undergoing general anesthesia. DESIGN AND SETTING: Retrospective study for which data were obtained prospectively from 1999 to 2004, at a tertiary university hospital. METHODS: We retrospectively studied 3107 patients over 11 years old presenting American Society of Anesthesiologists (ASA status I, II or III who underwent upper abdominal surgery under general anesthesia and were discharged to the recovery room. The preoperative conditions analyzed using logistic regression were: age, sex, ASA physical status, congestive heart failure, asthma, chronic obstructive pulmonary disease (COPD, respiratory failure and smoking. The outcomes or dependent variables included intraoperative and postoperative events: bronchospasm, hypoxemia, hypercapnia, prolonged intubation and airway secretion. RESULTS: Among these patients (1500 males, 1607 females, mean age 48 years, 1088 ASA I, 1402 ASA II and 617 ASA III, there were 80 congestive heart failures, 82 asthmatics, 122 with COPD, 21 respiratory failures and 428 smokers. Logistic regression analysis showed that female sex (p < 0.001, age over 70 years (p < 0.01, smoking (p < 0.001 and COPD (p < 0.02 significantly influenced pulmonary event development, particularly hypoxemia and bronchospasm, at both times but not in the same patients. Asthma and congestive heart failure cases did not present pulmonary events in the recovery room. CONCLUSION: In upper abdominal surgery under general anesthesia, female sex, age over 70, smoking and COPD were independent risk factors for intra and postoperative pulmonary events.

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)

This paper addresses the automated segmentation of multiple organs in upper abdominal computed tomography (CT) data. The aim of our study is to develop methods to effectively construct the conditional priors and use their prediction power for more accurate segmentation as well as easy adaptation to various imaging conditions in CT images, as observed in clinical practice. We propose a general framework of multi-organ segmentation which effectively incorporates interrelations among multiple organs and easily adapts to various imaging conditions without the need for supervised intensity information. The features of the framework are as follows: (1) A method for modeling conditional shape and location (shape-location) priors, which we call prediction-based priors, is developed to derive accurate priors specific to each subject, which enables the estimation of intensity priors without the need for supervised intensity information. (2) Organ correlation graph is introduced, which defines how the conditional priors are constructed and segmentation processes of multiple organs are executed. In our framework, predictor organs, whose segmentation is sufficiently accurate by using conventional single-organ segmentation methods, are pre-segmented, and the remaining organs are hierarchically segmented using conditional shape-location priors. The proposed framework was evaluated through the segmentation of eight abdominal organs (liver, spleen, left and right kidneys, pancreas, gallbladder, aorta, and inferior vena cava) from 134 CT data from 86 patients obtained under six imaging conditions at two hospitals. The experimental results show the effectiveness of the proposed prediction-based priors and the applicability to various imaging conditions without the need for supervised intensity information. Average Dice coefficients for the liver, spleen, and kidneys were more than 92%, and were around 73% and 67% for the pancreas and gallbladder, respectively. Copyright © 2015

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

We initiated a research program to develop a novel patient-reported outcome measure (PROM) to assess postoperative recovery from the perspective of abdominal surgery patients. In light of FDA recommendations, the first stage of our program aimed to, based on previous literature and expert input, develop a hypothesized conceptual framework portraying the health domains that are potentially relevant to the process of recovery after abdominal surgery. This study was conducted in three phases: (1) systematic review to identify PROMs with measurement properties appraised in the context of recovery after abdominal surgery, (2) content analysis to categorize the health domains covered by the PROMs according to the ICF, and (3) two-round Delphi study to gain expert input regarding which of these health domains are relevant to the process of recovery. Participants were experts in perioperative care identified through two major surgical societies (35 invited). The systematic review identified 19 PROMs covering 66 ICF domains. 23 experts (66%) participated in the Delphi process. After Round 2, experts agreed that 22 health domains (8 body functions, 14 activities and participation) are potentially relevant to the process of recovery after abdominal surgery. These domains were organized into a diagram, representing our hypothesized conceptual framework. This hypothesized conceptual framework is an important first step in our research program and will be further refined based on in-depth qualitative interviews with patients. The sound methodological approach used to derive this framework may be valuable for studies aimed to develop PROMs according to FDA standards.

Preoperative simulation and planning of surgical robot setup should accompany advanced robotic surgery if their advantages are to be further pursued. Feedback from the planning system will plays an essential role in computer-aided robotic surgery in addition to preoperative detailed geometric information from patient CT/MRI images. Surgical robot setup simulation systems for appropriate trocar site placement have been developed especially for abdominal surgery. The motion of the surgical robot can be simulated and rehearsed with kinematic constraints at the trocar site, and the inverse-kinematics of the robot. Results from simulation using clinical patient data verify the effectiveness of the proposed system.

Full Text Available Background: Postoperative pain is a significant problem in pediatrics. Preemptive administration of analgesics has recently emerged as a method to enhance pain management associated with surgery. The objective of this study was to compare the analgesic efficacy of a single-dose of preoperative oral ibuprofen versus acetaminophen in preventing pain after lower abdominal surgery in pediatrics. Methods: In this randomized, double-blind study, following lower abdominal surgery, 75 children, aging 3 to 12 years, were assigned to receive either ibuprofen 20 mg /kg (n=25 or acetaminophen 35 mg/kg (n=25 or placebo (n=25 2 hours before surgery. Agitation in recovery was measured and postoperative pain was quantified 3 and 24 hours after surgery by Oucher’s scale. The amount of postoperative analgesic needed in the ward was also assessed. Results: It was found that preoperative administration of ibuprofen and acetaminophen can reduce agitation in recovery but there was no difference in the agitation score between ibuprofen and acetaminophen groups (P=0.145. Agitation score was significantly lower in ibuprofen group compared to placebo (P>0.005. Similarly, patients in the acetaminophen group were considerably less agitated than those in the placebo group (P=0.002. No significant difference was observed in pain intensity 3 and 24 hours after operation between the three groups [(P=0.495 and (P=0.582 respectively]. The amount of postoperative analgesic needed during ward hospitalization was not significantly different among the three groups (P>0.005. Conclusion: These results provide evidence that preemptive acetaminophen and ibuprofen may reduce agitation during recovery but they neither improve the postoperative pain nor reduce analgesics consumption in ward Key words: Postoperative analgesia, Acetaminophen, Ibuprofen, Preemptive analgesia

The impact of intraoperative ventilation on postoperative pulmonary complications is not defined. The authors aimed at determining the effectiveness of protective mechanical ventilation during open abdominal surgery on a modified Clinical Pulmonary Infection Score as primary outcome and postoperative pulmonary function. Prospective randomized, open-label, clinical trial performed in 56 patients scheduled to undergo elective open abdominal surgery lasting more than 2 h. Patients were assigned by envelopes to mechanical ventilation with tidal volume of 9 ml/kg ideal body weight and zero-positive end-expiratory pressure (standard ventilation strategy) or tidal volumes of 7 ml/kg ideal body weight, 10 cm H2O positive end-expiratory pressure, and recruitment maneuvers (protective ventilation strategy). Modified Clinical Pulmonary Infection Score, gas exchange, and pulmonary functional tests were measured preoperatively, as well as at days 1, 3, and 5 after surgery. Patients ventilated protectively showed better pulmonary functional tests up to day 5, fewer alterations on chest x-ray up to day 3 and higher arterial oxygenation in air at days 1, 3, and 5 (mmHg; mean ± SD): 77.1 ± 13.0 versus 64.9 ± 11.3 (P = 0.0006), 80.5 ± 10.1 versus 69.7 ± 9.3 (P = 0.0002), and 82.1 ± 10.7 versus 78.5 ± 21.7 (P = 0.44) respectively. The modified Clinical Pulmonary Infection Score was lower in the protective ventilation strategy at days 1 and 3. The percentage of patients in hospital at day 28 after surgery was not different between groups (7 vs. 15% respectively, P = 0.42). A protective ventilation strategy during abdominal surgery lasting more than 2 h improved respiratory function and reduced the modified Clinical Pulmonary Infection Score without affecting length of hospital stay.

Major upper abdominal surgery is often associated with reduced health-related quality of life and reduced survival. Patients with upper abdominal malignancies often suffer from cachexia, represented by preoperative weight loss and sarcopenia (low skeletal muscle mass) and this might affect both health-related quality of life and survival. We aimed to investigate how health-related quality of life is affected by cachexia and how health-related quality of life relates to long-term survival after major upper abdominal surgery. From 2001 to 2006, 447 patients were included in a Norwegian multicenter randomized controlled trial in major upper abdominal surgery. In this study, six years later, these patients were analyzed as a single prospective cohort and survival data were retrieved from the National Population Registry. Cachexia was derived from patient-reported preoperative weight loss and sarcopenia as assessed from computed tomography images taken within three months preoperatively. In the original trial, self-reported health-related quality of life was assessed preoperatively at trial enrollment and eight weeks postoperatively with the health-related quality of life questionnaire Short Form 36. A majority of the patients experienced improved mental health-related quality of life and, to a lesser extent, deteriorated physical health-related quality of life following surgery. There was a significant association between preoperative weight loss and reduced physical health-related quality of life. No association between sarcopenia and health-related quality of life was observed. Overall survival was significantly associated with physical health-related quality of life both pre- and postoperatively, and with postoperative mental health-related quality of life. The association between health-related quality of life and survival was particularly strong for postoperative physical health-related quality of life.

Patients scheduled for heart valve surgery should be free of any oral infectious disorders that might pose a risk in the postoperative period. Few studies have been made on the dental conditions of such patients prior to surgery. The present study describes the most frequent prior oral diseases in this population group. A prospective, observational case-control study was designed involving 60 patients (30 with heart valve disease and 30 controls, with a mean age of 71 years in both groups). A dental exploration was carried out, with calculation of the DMFT (decayed, missing and filled teeth) index and recording of the periodontal parameters (plaque index, gingival bleeding index, periodontal pocket depth, and attachment loss). The oral mucosa was also examined, and panoramic X-rays were used to identify possible intrabony lesions. Significant differences in bacterial plaque index were observed between the two groups ( p <0.05), with higher scores in the patients with valve disease. Probing depth and the presence of moderate pockets were also greater in the patients with valve disease than among the controls ( p <0.01). Sixty percent of the patients with valve disease presented periodontitis. Patients scheduled for heart valve surgery should be examined for possible active periodontitis before the operation. Those individuals found to have periodontal disease should receive adequate periodontal treatment before heart surgery. Key words: Valve disease, aortic, mitral, heart surgery, periodontitis.

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

Full Text Available Background: The pain caused by surgery is one of the major problems of the patients. Therefore, pain reduction through using noninvasive and simple methods is one of the nursing priorities. This study aimed to evaluate the effect of reflexology massage on pain intensity in the patients following the abdominal surgery. Methods: This clinical trial was conducted on 90 patients undergoing abdominal surgery, referring to the Imam Khomeini Hospital in Tehran, Iran, in 2016. The participants were selected using the purposive sampling technique, and then randomly divided into three groups of 30 cases. The a 30-minute session of reflexology and simple massage were applied by the researcher for the first and second groups, respectively, after transferring the patients to the ward and regaining full consciousness. The pain was measured immediately, 10 min, and 24 h after the massage (30 min after the pre-test using the visual analogue scale. The data analysis was performed in the SPSS version 19, using the one-way and repeated measures ANOVA as well as Chi-square test. Results: According to the results of this study, 24 h after the intervention, the foot reflexology group had lower mean score of pain intensity (1.9±1.6, compared to the simple massage (3.3±1.64 and control groups (3.8±02 (P<0.001. The decrease in the pain score was significant between the groups only 10 min and 24 h after the intervention (P<0.001 Conclusion: As the findings of the present study indicated, the reflexology massage could alleviate the pain in the patients after abdominal surgery. Given the simple and non-invasive nature of this method, it could be used to reduce the pain in the patients along with other healthcare measures.

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)

Full Text Available Gut barrier loss has been implicated as a critical event in the occurrence of postoperative complications. We aimed to study the development of gut barrier loss in patients undergoing major non-abdominal surgery.Twenty consecutive children undergoing spinal fusion surgery were included. This kind of surgery is characterized by long operation time, significant blood loss, prolonged systemic hypotension, without directly leading to compromise of the intestines by intestinal manipulation or use of extracorporeal circulation. Blood was collected preoperatively, every two hours during surgery and 2, 4, 15 and 24 hours postoperatively. Gut mucosal barrier was assessed by plasma markers for enterocyte damage (I-FABP, I-BABP and urinary presence of tight junction protein claudin-3. Intestinal mucosal perfusion was measured by gastric tonometry (P(rCO2, P(r-aCO2-gap. Plasma concentration of I-FABP, I-BABP and urinary expression of claudin-3 increased rapidly and significantly after the onset of surgery in most children. Postoperatively, all markers decreased promptly towards baseline values together with normalisation of MAP. Plasma levels of I-FABP, I-BABP were significantly negatively correlated with MAP at (1/2 hour before blood sampling (-0.726 (p<0.001, -0.483 (P<0.001, respectively.

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.

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 appraise the level of evidence supporting the measurement properties of patient-reported outcome measures (PROMs) in the context of postoperative recovery after abdominal surgery. There is growing interest in using PROMs to support value-based care in abdominal surgery; however, to draw valid conclusions regarding patient-reported outcomes data, PROMs with robust measurement properties are required. Eight databases (MEDLINE, EMBASE, Biosis, PsycINFO, The Cochrane Library, CINAHL, Scopus, Web of Science) were searched for studies focused on the measurement properties of PROMs in the context of recovery after abdominal surgery. The methodological quality of individual studies was evaluated using the consensus-based COSMIN checklist. Evidence supporting the measurement properties of each PROM was synthetized according to standardized criteria and compared against the International Society of Quality of Life Research minimum standards for the selection of PROMs for outcomes research. We identified 35 studies evaluating 22 PROMs [12 focused on nonspecific surgical populations (55%), 4 focused on abdominal surgery (18%), and 6 generic PROMs (27%)]. The great majority of the studies (74%) received only poor or fair quality ratings. Measurement properties of PROMs were predominantly supported by limited or unknown evidence. None of the PROMs fulfilled International Society of Quality of Life Research's minimum standards, hindering specific recommendations. There is very limited evidence supporting the measurement properties of existing PROMs used in the context of recovery after abdominal surgery. This precludes the use of these PROMs to support value-based surgical care. Further research is required to bridge this major knowledge gap.

2010-07-01

Full Text Available Abstract Background Postoperative adhesions occur when fibrous strands of internal scar tissue bind anatomical structures to one another. The most common cause of intra-abdominal adhesions is previous intra-abdominal surgical intervention. Up to 74% of intestinal obstructions are caused by post surgical adhesions. Although a variety of methods and agents have been investigated to prevent post surgical adhesions, the problem of peritoneal adhesions remains largely unsolved. Materials serving as an adhesion barrier are much needed. Methods/Design This is a prospective, randomised, controlled, patient blinded and observer blinded, single centre phase I-II trial, which evaluates the safety of A-Part® Gel as an adhesion prophylaxis after major abdominal wall surgery, in comparison to an untreated control group. 60 patients undergoing an elective median laparotomy without prior abdominal surgery are randomly allocated into two groups of a 1:1- ratio. Safety parameter and primary endpoint of the study is the occurrence of wound healing impairment or peritonitis within 28 (+10 days after surgery. The frequency of anastomotic leakage within 28 days after operation, occurrence of adverse and serious adverse events during hospital stay up to 3 months and the rate of adhesions along the scar within 3 months are defined as secondary endpoints. After hospital discharge the investigator will examine the enrolled patients at 28 (+10 days and 3 months (±14 days after surgery. Discussion This trial aims to assess, whether the intra-peritoneal application of A-Part® Gel is safe and efficacious in the prevention of post-surgical adhesions after median laparotomy, in comparison to untreated controls.

Previous abdominal surgery has traditionally been considered an additional element of difficulty to later laparoscopic procedures. The aim of the study is to analyze the effect of previous surgery on the feasibility and safety of laparoscopic liver resection (LLR), and its role as a risk factor for conversion. After matching, 349 LLR in patients known for previous abdominal surgery (PS group) were compared with 349 LLR on patients with a virgin abdomen (NPS group). Subgroup analysis included 161 patients with previous upper abdominal surgery (UPS subgroup). Feasibility and safety were evaluated in terms of conversion rate, reasons for conversion and outcomes, and risk factors for conversion assessed via uni/multivariable analysis. Conversion rate was 9.4%, and higher for PS patients compared with NPS patients (13.7% versus 5.1%, P = .021). Difficult adhesiolysis resulted the commonest reason for conversion in PS group (5.7%). However, operative time (P = .840), blood loss (P = .270), transfusion (P = .650), morbidity rate (P = .578), hospital stay (P = .780), and R1 rate (P = .130) were comparable between PS and NPS group. Subgroup analysis confirmed higher conversion rates for UPS patients (23%) compared with both NPS (P = .015) and PS patients (P = .041). Previous surgery emerged as independent risk factor for conversion (P = .033), alongside the postero-superior location and major hepatectomy. LLR are feasible in case of previous surgery and proved to be safe and maintain the benefits of LLR carried out in standard settings. However, a history of surgery should be considered a risk factor for conversion.

Data on specific abdominal surgery and Cushing's syndrome are infrequent and are usually included in the adrenalectomy reports. Current literature suggests the feasibility and reproducibility of the surgical adrenalectomies for patients diagnosed with non-functioning tumours and functioning adrenal tumours including pheochromocytoma, Conn's syndrome and Cushing's syndrome. Medical treatment for Cushing's syndrome is feasible but follow-up or clinical situations force the patient to undergo a surgical procedure. Laparoscopic surgery has become a gold standard nowadays in a broad spectrum of pathologies. Laparoscopic adrenalectomies are also standard procedures nowadays. However, despite the different characteristics and clinical disorders related to the laparoscopically removed adrenal tumours, the intraoperative and postoperative outcomes do not significantly differ in most cases between the different groups of patients, techniques and types of tumours. Tumour size, hormonal type and surgeon's experience could be different factors that predict intraoperative and postoperative complications. Transabdominal and retroperitoneal approaches can be considered. Outcomes for Cushing's syndrome do not differ depending on the surgical approach. Novel technologies and approaches such as single-port surgery or robotic surgery have proven to be safe and feasible. Laparoscopic adrenalectomy is a safe and feasible approach to adrenal pathology, providing the patients with all the benefits of minimally invasive surgery. Single-port access and robotic surgery can be performed but more data are required to identify their correct role between the different surgical approaches. Factors such as surgeon's experience, tumour size and optimal technique can affect the outcomes of this surgery.

To report on outcomes of gonioscopy-assisted transluminal trabeculotomy (GATT) in eyes with prior incisional glaucoma surgery. A retrospective review was performed for all patients who underwent a GATT procedure with a history of prior incisional glaucoma surgery. Thirty-five eyes of 35 patients were treated. The mean age was 67.7 years. Nineteen eyes had a prior trabeculectomy, 13 eyes had a prior glaucoma drainage device, 4 eyes had a prior trabectome, and 5 eyes had prior endocyclophotocoagulation. Mean follow-up time was 22.7 months. For all eyes, the mean preoperative intraocular pressure (IOP) (SD) was 25.7 (6.5) mm Hg on 3.2 (1.0) glaucoma medications and at 24 months, the mean IOP (SD) was 15.4 (4.9) mm Hg on 2.0 (1.4) glaucoma medications (P<0.001). The prior trabeculectomy group had a preoperative IOP (SD) of 24.6 (6.4) mm Hg on 3.2 (1.0) medications and at month 24, the mean IOP (SD) was 16.7 (5.6) mm Hg on 2.1 (1.4) glaucoma medications. In the prior glaucoma drainage device group, the mean preoperative IOP (SD) was 27.0 (7.1) mm Hg on 3.4 (1.1) glaucoma medications and at 24 months, the mean IOP (SD) was 12.9 (2.6) mm Hg on 2.1 (1.2) glaucoma medications. At 24 months, the cumulative proportion of failure was 0.4 and the cumulative proportion of reoperation was 0.29. GATT appears to be safe and successful in treating 60% to 70% of open-angle patients with prior incisional glaucoma surgery. When considering all eyes, there was a significant decrease in IOP and required glaucoma medications at 24 months. This surgery should be considered in certain patients with open angles who have failed a primary traditional glaucoma surgery.

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

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.

BACKGROUND: Emergency abdominal surgery carries a considerable risk of death and postoperative complications. Early detection and timely management of complications may reduce mortality. The aim was to evaluate the effect and feasibility of intermediate care compared with standard ward care...... ward within 24 h of emergency abdominal surgery. Participants were randomized to either intermediate care or standard surgical ward care after surgery. The primary outcome was 30-day mortality. RESULTS: In total, 286 patients were included in the modified intention-to-treat analysis. The trial...... was terminated after the interim analysis owing to slow recruitment and a lower than expected mortality rate. Eleven (7·6 per cent) of 144 patients assigned to intermediate care and 12 (8·5 per cent) of 142 patients assigned to ward care died within 30 days of surgery (odds ratio 0·91, 95 per cent c.i. 0·38 to 2...

Subcostal transversus abdominis plane (TAP) catheters have been reported to be an effective method of providing analgesia after upper abdominal surgery. We compared their analgesic efficacy with that of epidural analgesia after major upper abdominal surgery in a randomised controlled trial. Adult patients undergoing elective open hepatobiliary or renal surgery were randomly allocated to receive subcostal TAP catheters (n=29) or epidural analgesia (n=33), in addition to a standard postoperative analgesic regimen comprising of regular paracetamol and tramadol as required. The TAP group patients received bilateral subcostal TAP catheters and 1 mg.kg(-1) bupivacaine 0.375% bilaterally every 8 h. The epidural group patients received an infusion of bupivacaine 0.125% with fentanyl 2 μg.ml(-1) . The primary outcome measure was visual analogue pain scores during coughing at 8, 24, 48 and 72 h after surgery. We found no significant differences in median (IQR [range]) visual analogue scores during coughing at 8 h between the TAP group (4.0 (2.3-6.0 [0-7.5])) and epidural group (4.0 (2.5-5.3) [0-8.5])) and at 72 h (2.0 (0.8-4.0 [0-5]) and 2.5 (1.0-5.0 [0-6]), respectively). Tramadol consumption was significantly greater in the TAP group (p=0.002). Subcostal TAP catheter boluses may be an effective alternative to epidural infusions for providing postoperative analgesia after upper abdominal surgery. © 2011 The Authors.

Transversus abdominal plane (TAP) block for postoperative pain management: a review.

Science.gov (United States)

Jakobsson, Jan; Wickerts, Liselott; Forsberg, Sune; Ledin, Gustaf

2015-01-01

Transversus abdominal plane (TAP) block has a long history and there is currently extensive clinical experience around TAP blocks. The aim of this review is to provide a summary of the present evidence on the effects of TAP block and to provide suggestions for further studies. There are several approaches to performing abdominal wall blocks, with the rapid implementation of ultrasound-guided technique facilitating a major difference in TAP block performance. During surgery, an abdominal wall block may also be applied by the surgeon from inside the abdominal cavity. Today, there are more than 11 meta-analyses providing a compiled evidence base around the effects of TAP block. These analyses include different procedures, different techniques of TAP block administration and, importantly, they compare the TAP block with a variety of alternative analgesic regimes. The effects of TAP block during laparoscopic cholecystectomy seem to be equivalent to local infiltration analgesia and also seem to be beneficial during laparoscopic colon resection. The effects of TAP are more pronounced when it is provided prior to surgery and these effects are local anaesthesia dose-dependent. TAP block seems an interesting alternative in patients with, for example, severe obesity where epidural or spinal anaesthesia/analgesia is technically difficult and/or poses a risk. There is an obvious need for further high-quality studies comparing TAP block prior to surgery with local infiltration analgesia, single-shot spinal analgesia, and epidural analgesia. These studies should be procedure-specific and the effects should be evaluated, both regarding short-term pain and analgesic requirement and also including the effects on postoperative nausea and vomiting, recovery of bowel function, ambulation, discharge, and protracted recovery outcomes (assessed by e.g., postoperative quality of recovery scale).

Splenic involvement secondary to blunt abdominal trauma is often treated by performing a splenectomy. The severity of the post-splenectomy syndrome is currently well known (blood loss, sepsis), so there is an increasing tendency to preserve the spleen. The case is presented of splenic preservation after blunt abdominal trauma with hilum involvement, emphasising the role of Floseal as a haemostatic agent, as well as the use of resorbable meshes to preserve the spleen. A 22-year-old woman presenting with a grade IV splenic lesion secondary to a blunt abdominal trauma after a traffic accident. Partial splenic resection was performed and bleeding was controlled with Floseal and use of a reinforcing polyglycolic acid mesh. No postoperative complications occurred, being discharged on day 5. The long-term follow-up has been uneventful. The use of haemostatic agents such as thrombin and the gelatine gel (FloSeal) and the use of polyglycolic acid meshes enable spleen-preserving surgery, making it a feasible and reproducible procedure and an alternative to classical splenectomy.

Abdominal Non-Hodgkin lymphomas (NHL) are the most common extra nodal presentation of pediatric NHL. Our aim is to assess the role of surgery as a risk factor and to evaluate the impact of risk-adjusted systemic chemotherapy on survival of patients with stages II and III disease. This study included 35 pediatric patients with abdominal NHL treated over five years at South Egypt Cancer Institute (SECI), Assiut University, between January 2005 and January 2010. The data of every patient included: Age, sex, and presentation, staging work up to determine extent of the disease and the type of resection performed, histopathological examination, details of chemotherapy, disease free survival and overall survival. The study included 25 boys and 10 girls with a median age of six years (range: 2.5:15). Thirty patients (86%) presented with abdominal pain, 23 patients (66%) presented with abdominal mass and distention, 13 patients (34%) presented with weight loss, and intestinal obstruction occurred in six patients (17%). The ileo-cecal region and abdominal lymph nodes were the commonest sites (48.5%, 21% respectively). Burkitt's lymphoma was the most common histological type in 29 patients (83%). Ten (28.5%) stage II (group A) and 25 (71.5%) stage III (group B). Complete resections were performed in 10 (28.5%), debulking in 6 (17%) and imaging guided biopsy in 19 (54%). A11 patients received systemic chemotherapy. The median follow up duration was 63 months (range 51-78 months). The parameters that significantly affect the overall survival were stage at presentation complete resection for localized disease. In conclusion, the extent of disease at presentation is the most important prognostic factor in pediatric abdominal NHL. Surgery is restricted to defined situations such as; abdominal emergencies, diagnostic biopsy and total tumor extirpation in localized disease. Chemotherapy is the cornerstone in the management of pediatric abdominal NHL.

This paper presents an approach for kidney segmentation on abdominal CT images as the first step of a virtual reality surgery system. Segmentation for medical images is often challenging because of the objects' complicated anatomical structures, various gray levels, and unclear edges. A coarse to fine approach has been applied in the kidney segmentation using Chan-Vese model (C-V model) and anatomy prior knowledge. In pre-processing stage, the candidate kidney regions are located. Then C-V model formulated by level set method is applied in these smaller ROI, which can reduce the calculation complexity to a certain extent. At last, after some mathematical morphology procedures, the specified kidney structures have been extracted interactively with prior knowledge. The satisfying results on abdominal CT series show that the proposed approach keeps all the advantages of C-V model and overcome its disadvantages.

A prior analysis of patients undergoing laparotomy for ovarian malignancies at our institution revealed an increased rate of intra-abdominal collections using HA-CMC film during debulking surgery. The primary objective of the current study was to determine whether the use of HA-CMC is associated with the development of postoperative intra-abdominal collections in patients undergoing laparotomy for uterine or cervical malignancies. We retrospectively identified all laparotomies performed for these malignancies from 3/1/05 to 12/31/07. We identified cases involving the use of HA-CMC via billing records and operative reports. Intra-abdominal collections were defined as localized intraperitoneal fluid accumulations in the absence of re-accumulating ascites. We noted incidences of intra-abdominal collections, as well as other complications. Appropriate statistical tests were applied using SPSS 15.0. We identified 169 laparotomies in which HA-CMC was used and 347 in which HA-CMC was not used. The following were statistically similar in both cohorts: age, body mass index (BMI), primary site, surgery for recurrent disease, prior intraperitoneal surgery, and extent of current surgery. Intra-abdominal collections were seen in 6 (3.6%) of 169 HA-CMC cases compared to 10 (2.9%) of 347 non-HA-CMC cases (p=0.7). The rate of infected collections was similar in both groups (1.2% vs. 1.4%). In the subgroup that underwent tumor debulking, intra-abdominal collections were seen in 3 (11.5%) of 26 HA-CMC cases compared to 2 (5.4%) of 37 non-HA-CMC cases (p=0.6). HA-CMC use does not appear to be associated with postoperative intra-abdominal collections in patients undergoing laparotomy for uterine or cervical cancer. Copyright © 2010 Elsevier Inc.

Robotic Transversus Abdominis Release (TAR: is it possible to offer minimally invasive surgery for abdominal wall complex defects?

Directory of Open Access Journals (Sweden)

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.

It is known that smokers and patients with chronic obstructive pulmonary disease (COPD) experience a higher rate of pulmonary-related complications following abdominal surgery. The impact of anesthetic technique (regional [RA] versus general [GA] versus combination of both) on the complication rate has not been established. This study examined the outcomes of abdominal surgery performed using RA (epidural or continuous spinal) as the sole anesthetic technique in patients with severe pulmonary impairment (SPI). We reviewed a series of 8 general surgery cases performed using RA alone (T4-T6 sensory level) in patients with SPI, as evidenced by an forced expiratory volume in 1 second (FEV(1)) less than 50% predicted and/or home oxygen requirement. One patient also received postoperative epidural analgesia. FEV(1) ranged from 0.3 to 1.84 L; 3 patients required home oxygen therapy, and 5 of the 8 were American Society of Anesthesiology (ASA) class 4. Operations included segmental colectomy (n = 2), open cholecystectomy (n = 1), incisional herniorrhaphy (n = 1), and laparoscopic herniorrhaphy (n = 4). Intraoperative conditions were adequate with RA alone for successful completion of the procedure in all cases. All patients recovered uneventfully except for 1 who developed postoperative pneumonia that resolved with standard therapy. Length of stay was less than 24 hours for 5 of 8 patients. Mortality was 0%. Abdominal surgery can be safely performed using RA alone in selected high-risk patients, making this option an attractive alternative to GA for those with severe pulmonary impairment.

The purpose of this study was to examine the effectiveness of aromatherapy with ginger essential oil on nausea and vomiting in abdominal surgery patients. This was a quasi-experimental study with a nonequivalent control group and repeated measures. The experimental group (n = 30) received ginger essential oil inhalation. The placebo control group (n = 30) received normal saline inhalation. The level of postoperative nausea and vomiting was measured using a Korean version of the Index of Nausea, Vomiting, and Retching (INVR) at baseline and at 6, 12, and 24 h after aromatherapy administration. The data were collected from July 23 to August 22, 2012. Nausea and vomiting scores were significantly lower in the experimental group with ginger essential oil inhalation than those in the placebo control group with normal saline. In the experimental group, the nausea and vomiting scores decreased considerably in the first 6 h after inhaled aromatherapy with ginger essential oil. Findings indicate that ginger essential oil inhalation has implications for alleviating postoperative nausea and vomiting in abdominal surgery patients.

Incisional hernia is a common long-term complication to abdominal surgery, occurring in more than 20% of all patients. Some of these hernias become giant and affect patients in several ways. This patient group often experiences pain, decreased perceived body image, and loss of physical function......, which results in a need for surgical repair of the giant hernia, known as abdominal wall reconstruction. In the current thesis, patients with a giant hernia were examined to achieve a better understanding of their physical and psychological function before and after abdominal wall reconstruction. Study...... was lacking. Study II was a case-control study of the effects of an enhanced recovery after surgery pathway for patients undergoing abdominal wall reconstruction for a giant hernia.

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.

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

In the current study, a case of recurrent desmoplastic small round cell tumor (DSRCT) is presented, which was successfully treated by repetitive debulking surgery. In May 2010, a 39-year-old male, with a history of surgical resection of intra-abdominal DSRCT, visited the Ibaraki Medical Center, Tokyo Medical University Hospital (Ami, Japan) with severe lower abdominal discomfort. Abdominal computed tomography revealed a large tumor in the pouch of Douglas with a small number of nodules in the abdominal cavity. The recurrent DSRCT was diagnosed and removed via lower anterior resection; however, complete resection was impossible due to multiple peritoneal metastases. One year later, the patient developed pain in the right groin due to the growth of metastasized tumor cells in the groin lymph nodes. The affected lymph nodes were removed utilizing an extra-peritoneal approach. At the time of writing, the patient continues to survive without any symptoms 60 months since the initial surgery. In conclusion, surgical debulking is a significant procedure for relieving patient symptoms as well as improving the survival time of patients with metastatic and recurrent DSRCT.

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....

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.

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)

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.

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.

General anesthesia usually requires mechanical ventilation, which is traditionally accomplished with constant tidal volumes in volume- or pressure-controlled modes. Experimental studies suggest that the use of variable tidal volumes (variable ventilation) recruits lung tissue, improves pulmonary function and reduces systemic inflammatory response. However, it is currently not known whether patients undergoing open abdominal surgery might benefit from intraoperative variable ventilation. The PROtective VARiable ventilation trial ('PROVAR') is a single center, randomized controlled trial enrolling 50 patients who are planning for open abdominal surgery expected to last longer than 3 hours. PROVAR compares conventional (non-variable) lung protective ventilation (CV) with variable lung protective ventilation (VV) regarding pulmonary function and inflammatory response. The primary endpoint of the study is the forced vital capacity on the first postoperative day. Secondary endpoints include further lung function tests, plasma cytokine levels, spatial distribution of ventilation assessed by means of electrical impedance tomography and postoperative pulmonary complications. We hypothesize that VV improves lung function and reduces systemic inflammatory response compared to CV in patients receiving mechanical ventilation during general anesthesia for open abdominal surgery longer than 3 hours. PROVAR is the first randomized controlled trial aiming at intra- and postoperative effects of VV on lung function. This study may help to define the role of VV during general anesthesia requiring mechanical ventilation. Clinicaltrials.gov NCT01683578 (registered on September 3 3012).

This study compared the total joint arthroplasty (TJA) surgical outcomes of patients who had bariatric surgery prior to TJA to TJA patients who were candidates but did not have bariatric surgery. Patients were retrospectively grouped into: Group 1 (n=69), those with bariatric surgery >2 years prior to TJA, Group 2 (n=102), those with surgery within 2 years of TJA, and Group 3 (n=11,032), those without bariatric surgery. In Group 1, 2.9% (95%CI 0.0–6.9%) had complications within 1 year compared to 5.9% (95%CI 1.3–10.4%) in Group 2, and 4.1% (95%CI 3.8–4.5%) in Group 3. 90-day readmission (7.2%, 95%CI 1.1–13.4%) and revision density (3.4/100 years of observation) was highest in Group 1. Bariatric surgery prior to TJA may not provide dramatic improvements in post-operative TJA surgical outcomes. PMID:24674730

Szender, J.B.; Hall, K.L.; Kost, E.R.

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

Experimental studies showed that controlled variable ventilation (CVV) yielded better pulmonary function compared to non-variable ventilation (CNV) in injured lungs. We hypothesized that CVV improves intraoperative and postoperative respiratory function in patients undergoing open abdominal surgery. Fifty patients planned for open abdominal surgery lasting >3 h were randomly assigned to receive either CVV or CNV. Mean tidal volumes and PEEP were set at 8 ml kg -1 (predicted body weight) and 5 cm H 2 O, respectively. In CVV, tidal volumes varied randomly, following a normal distribution, on a breath-by-breath basis. The primary endpoint was the forced vital capacity (FVC) on postoperative Day 1. Secondary endpoints were oxygenation, non-aerated lung volume, distribution of ventilation, and pulmonary and extrapulmonary complications until postoperative Day 5. FVC did not differ significantly between CVV and CNV on postoperative Day 1, 61.5 (standard deviation 22.1) % vs 61.9 (23.6) %, respectively; mean [95% confidence interval (CI)] difference, -0.4 (-13.2-14.0), P=0.95. Intraoperatively, CVV did not result in improved respiratory function, haemodynamics, or redistribution of ventilation compared to CNV. Postoperatively, FVC, forced expiratory volume at the first second (FEV 1 ), and FEV 1 /FVC deteriorated, while atelectasis volume and plasma levels of interleukin-6 and interleukin-8 increased, but values did not differ between groups. The incidence of postoperative pulmonary and extrapulmonary complications was comparable in CVV and CNV. In patients undergoing open abdominal surgery, CVV did not improve intraoperative and postoperative respiratory function compared with CNV. NCT 01683578.

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.

Full Text Available Transversus abdominal plane (TAP block has a long history and there is currently extensive clinical experience around TAP blocks. The aim of this review is to provide a summary of the present evidence on the effects of TAP block and to provide suggestions for further studies. There are several approaches to performing abdominal wall blocks, with the rapid implementation of ultrasound-guided technique facilitating a major difference in TAP block performance. During surgery, an abdominal wall block may also be applied by the surgeon from inside the abdominal cavity. Today, there are more than 11 meta-analyses providing a compiled evidence base around the effects of TAP block. These analyses include different procedures, different techniques of TAP block administration and, importantly, they compare the TAP block with a variety of alternative analgesic regimes. The effects of TAP block during laparoscopic cholecystectomy seem to be equivalent to local infiltration analgesia and also seem to be beneficial during laparoscopic colon resection. The effects of TAP are more pronounced when it is provided prior to surgery and these effects are local anaesthesia dose-dependent. TAP block seems an interesting alternative in patients with, for example, severe obesity where epidural or spinal anaesthesia/analgesia is technically difficult and/or poses a risk. There is an obvious need for further high-quality studies comparing TAP block prior to surgery with local infiltration analgesia, single-shot spinal analgesia, and epidural analgesia. These studies should be procedure-specific and the effects should be evaluated, both regarding short-term pain and analgesic requirement and also including the effects on postoperative nausea and vomiting, recovery of bowel function, ambulation, discharge, and protracted recovery outcomes (assessed by e.g., postoperative quality of recovery scale.

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

Previous studies have shown that preincisional epidural morphine, bupivacaine, and ketamine combined with epidural anesthesia (EA) and general anesthesia (GA) provided pre-emptive analgesia for upper abdominal surgery. Recent studies reported that ultralow-dose naloxone enhanced the antinociceptive effect of morphine in rats. This study investigated the benefits of preincisional and postoperative epidural morphine + ropivacaine + ketamine + naloxone (M + R + K + N) treatment for achieving postoperative pain relief in upper abdominal surgery. Eighty American Society of Anesthesiology I-II patients scheduled for major upper abdominal surgery were allocated to four groups in a randomized, single-blinded study. All patients received combined GA and EA with a continuous epidural infusion of 2% lidocaine (6-8 mL/h) 30 minutes after pain regimen. After GA induction, in Group I, an epidural pain control regimen (total 10 mL) was administered using 1% lidocaine (8 mL) + morphine (2 mg) + ropivacaine (20 mg; M + R); in Group II, 1% lidocaine 8 (mL) + morphine (2 mg) + ropivacaine (20 mg) + ketamine (20 mg; M + R + K); in Group III, 1% lidocaine (8 mL) + morphine (2 mg) + ropivacaine (20 mg) + naloxone (2 μg; M + R + N); and in Group IV, 1% lidocaine (8 mL) + morphine (2 mg) + ropivacaine (20 mg) + ketamine (20 mg) + naloxone (2 μg; M + R + K + N), respectively. All patients received patient-controlled epidural analgesia (PCEA) with different pain regimens to control subsequent postoperative pain for 3 days following surgery. During the 3-day period following surgery, PCEA consumption (mL), numerical rating scale (NRS) score while cough/moving, and analgesic-related adverse effects were recorded. Total PCEA consumption for the 3-day observation period was 161.5±17.8 mL, 103.2±21.7 mL, 152.4±25.6 mL, and 74.1±16.9 mL for Groups I, II, III, and IV, respectively.

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.

Full Text Available Colorectal carcinoma in children and adolescents is extremely rare, with an annual incidence <0.3 cases per million, most frequently reported in the second decade of life. It accounts for severe morbidity and poor prognosis owing to the low index of suspicion, delayed diagnosis, advanced stage at presentation and the aggressive tumor nature. Patients present with abdominal pain, vomiting, constipation, abdominal distension, rectal tenesmus, iron-deficiency anemia, change in bowel habit and weight loss. Rectal bleeding is an uncommon presentation in children. Bowel obstruction presents frequently in children compared to adults. In 90% of pediatric cases, colorectal carcinoma occurs sporadically. In 10%, predisposing conditions and syndromes are identified. We present a case study of a 12-year-old female with advanced colorectal cancer without a predisposing disease or syndrome, who received radio-chemotherapy ten weeks prior to radical abdominopelvic surgery, followed by radio-chemotherapy postoperatively, with a positive outcome.

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.

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.

The aim of this study was to prospectively evaluate ostomy-related complications and describe ostomy configuration in patients undergoing acute abdominal surgery. The study sample comprised 144 patients with a median age of 67 years (IOR: 53.5-78 years) who underwent an intestinal ostomy as part of an acute abdominal surgical procedure. The research setting was the surgical and gynecological clinics at the Sahlgrenska University Hospital in Gothenburg, Sweden. Ostomy configuration, diameter, height, and the presence of stomal and peristomal complications were assessed by a WOC nurse 1 to 2 times while in hospital, once at the ostomy outpatient clinic 2 weeks after discharge, and at 3, 6, 12, and 24 months following ostomy creation. The types of ostomies evaluated were end colostomy (58%), end ileostomy (18%), loop ileostomy (17%), and loop colostomy (7%). Most stomal or peristomal complications occurred within 1 year after surgery (31 of 57; 54.4%). Necrosis, separation, and stenosis were most common in patients with an end colostomy. Peristomal skin complications occurred in 45% of subjects during the first 6 months after surgery. The ostomy's diameter decreased significantly during the hospital course and over the first 2 weeks following hospital discharge in patients with end colostomy (Postomy had peristomal skin problems ranging between 21% and 57% over this time period. The frequency of using a pouching system that incorporated convexity was highest in the case of loop ileostomy, used in 67% at 6 months. During the first 2 weeks after discharge, the physical configuration of the ostomy evolves and the pouching system must be frequently adjusted by a WOC nurse. Stomal and peristomal complications are prevalent during the first 2 postoperative years and especially during the first 6 months.

Computerized Tomography has gained an important role in the diagnosis of the complications of prosthetic surgery of the abdominal aorta: the importance of such complications come from their frequency, which is proportional to the increasing number of interventions, and their severity. The authors investigated the CT patterns of the most frequent complications. 24 patients referred for strongly suspected postoperative complications were examined in 2 years: fever and leukocytosis (20 cases) and progressive anemia (4 cases) were the most frequent findings. The operation had been performed 7± 12 weeks before (2 patients were excluded because surgery dated less than 3 weeks. 14 patients had infective complications: thickening (57%) and inhomogeneity (43%) of the periprosthetic wrap and ectopic gas bubble (78%) were the most frequent Computerized Tomography findings. The authors also observed 2 periprosthetic hematomas, 1 aneurysm relapse and 1 prosthetic graft rupture. In conclusion, CT confirmed its important role in the study of the complications of prosthetic aortic surgery, despite its know poor specificity in the demonstration of the aorta in the first 2-3 months postoperatively, in the initial stages of infection and in the diagnosis of aorta-enteric fistulas

Evidence or eminence in abdominal surgery: Recent improvements in perioperative care

Science.gov (United States)

Segelman, Josefin; Nygren, Jonas

2014-01-01

Repeated surveys from Europe, the United States, Australia, and New Zealand have shown that adherence to an evidence-based perioperative care protocol, such as Enhanced Recovery After Surgery (ERAS), has been generally low. It is of great importance to support the implementation of the ERAS protocol as it has been shown to improve outcomes after a number of surgical procedures, including major abdominal surgery. However, despite an increasing awareness of the importance of structured perioperative management, the implementation of this complex protocol has been slow. Barriers to implementation involve both patient- and staff-related factors as well as practice-related issues and resources. To support efficient and successful implementation, further educational and structural measures have to be made on a national or regional level to improve the standard of general health care. Besides postoperative morbidity, biological and physiological variables have been quite commonly reported in previous ERAS studies. Little information, however, has been obtained on cost-effectiveness, long-term outcomes, quality of life and patient-related outcomes, and these issues remain important areas of research for future studies.

To assess the outcomes of endovascular aortic aneurysm repair (EVAR) for the treatment of an abdominal aortic aneurysm in patients undergoing curative surgical treatment for concomitant abdominal malignancy. The study included 12 patients with abdominal neoplasia and an abdominal aortic aneurysm (AAA), which was treated by surgery and stent EVAR. The neoplasm consisted of the gastric, colorectal, pancreas, prostate, and gall bladder. The follow up period was 3-21 months (mean 11.8 months). All medical records and imaging analyses were reviewed by CTA and/or color Doppler US, retrospectively. Successful endoluminal repair was accomplished in all twelve patients. The mean interval time between EVAR and surgery was 58.6 days. Small amounts of type 2 endoleaks were detected in two patients (17%). One patient developed adult respiratory distress syndrome after Whipple's operation 20 days after surgery, which led to hopeless discharge. No procedure-related mortality, morbidity, or graft-related infection was noted. Exclusion of AAA in patients with accompanying malignancy show with a relatively low procedure morbidity and mortality. Hence, endoluminal AAA repair in patients with synchronous neoplasia may allow greater flexibility in the management of an offending malignancy

a comprehensive assessment of the water balance on the basis of daily, cumulative balance and 10% of the body weight gain and their role in the development of early complications after major abdominal surgery. A retrospective study of the perioperative period in 150 patients who underwent major abdomi- nal surgery was performed. The physical condition of the patients corresponded to ASA 3 class. The average age was 46 (38-62) years. The following stages ofresearch: an analysis of daily balance and cumulative balance in complicated and uncomplicated group and their role in the development of complications; the timing of development ofcomplications and possible relationship with fluid overload and the development of complications; changes in the level of albumin within 10 days of the postoperative period. The analysis of complications didn't show significant differences between complicated and uncomplicated groups according to the water balance during the surgery and by the end of the first day. When constructing the area under the ROC curve (A UROC) low resolution ofthe balance in intraoperative period and the first day and the balance on the second day to predict complications was shown. Significant diferences according to the cumulative balance was observed from the third day of the postoperative period Also with the third day of the postoperative period there is a good resolution for prediction ofpostoperative complications according to the cumulative balance with the cut-offpoint > of 50,7 ml/kg. the excessive infusion therapy is a predictor of adverse outcome in patients after major abdominal surgery. Therefore, after 3 days of postoperative period it is important to maintain mechanisms for the excretion of excess fluid or limitations of infusion therapy.

Abdominal hernias are a common clinical problem Clinical diagnosis of abdominal hernias can sometimes be challenging, particularly in obese patients or patients with previous abdominal surgery. CT scan of the abdomen allows visualization of hernias and their contents and the differentiation from other masses of the abdominal wall such as tumors, hematomas and abscesses. Moreover, CT may identify complications such as incarceration, bowel obstruction, volvulus and strangulation. This study illustrates the CT scan findings observed in different types of abdominal wall hernias. (author)

Evaluation of outcomes after aesthetic surgery still is a challenge in plastic surgery. The evaluation frequently is based on subjective criteria. This study used a new clinical grading scale to evaluate aesthetic results for plastic surgeries to the abdomen. The method scores each of the following five parameters: volume of subcutaneous tissue, contour, excess of skin, aspect of the navel, and quality of the scar on the abdominal wall. The scale options are 0 (poor), 1 (fair), and 2 (good), and the total rate can range from 0 to 10. The study included 40 women ages 18-53 years. Of these 40 women, 20 underwent traditional abdominoplasty, and 20 had liposuction alone. Preoperatively and at least 1 year later, photographic results were analyzed and scored by three independent plastic surgeons. In the abdominoplasty group, the average grade rose from 2.9±0.4 to 6.8±0.4 postoperatively. In the liposuction group, the average grade was 5.3±0.5 preoperatively and 7.7±0.4 postoperatively. In both groups, the average postoperative grade was significantly higher than the preoperative grade. The mean scores for groups A and L were significantly different, demonstrating that the scale was sensitive in identifying different anatomic abnormalities in the abdomen. The rating scale used for the aesthetic evaluation of the abdomen was effective in the analysis of two different procedures: conventional abdominoplasty and liposuction. Abdominoplasty provided the greater gain according to a comparison of the pre- and postoperative scores.

Post-operative pulmonary complications add to the morbidity and mortality of surgical patients, in particular after general anesthesia >2 hours for abdominal surgery. Whether a protective mechanical ventilation strategy with higher levels of positive end-expiratory pressure (PEEP) and repeated recruitment maneuvers; the "open lung strategy", protects against post-operative pulmonary complications is uncertain. The present study aims at comparing a protective mechanical ventilation strategy with a conventional mechanical ventilation strategy during general anesthesia for abdominal non-laparoscopic surgery. The PROtective Ventilation using HIgh versus LOw positive end-expiratory pressure ("PROVHILO") trial is a worldwide investigator-initiated multicenter randomized controlled two-arm study. Nine hundred patients scheduled for non-laparoscopic abdominal surgery at high or intermediate risk for post-operative pulmonary complications are randomized to mechanical ventilation with the level of PEEP at 12 cmH(2)O with recruitment maneuvers (the lung-protective strategy) or mechanical ventilation with the level of PEEP at maximum 2 cmH(2)O without recruitment maneuvers (the conventional strategy). The primary endpoint is any post-operative pulmonary complication. The PROVHILO trial is the first randomized controlled trial powered to investigate whether an open lung mechanical ventilation strategy in short-term mechanical ventilation prevents against postoperative pulmonary complications.

Full Text Available Surgical site infections remain one of the most frequent complications following abdominal surgery and cause substantial costs, morbidity and mortality.To assess the effectiveness of wound edge protectors in open abdominal surgery in reducing surgical site infections.A systematic literature search was conducted according to a prespecified review protocol in a variety of data-bases combined with hand-searches for randomized controlled trials on wound edge protectors in patients undergoing laparotomy. A qualitative and quantitative analysis of included trials was conducted.We identified 16 randomized controlled trials including 3695 patients investigating wound edge protectors published between 1972 and 2014. Critical appraisal uncovered a number of methodological flaws, predominantly in the older trials. Wound edge protectors significantly reduced the rate of surgical site infections (risk ratio 0.65; 95%CI, 0.51-0.83; p = 0.0007; I2 = 52%. The results were robust in a number of sensitivity analyses. A similar effect size was found in the subgroup of patients undergoing colorectal surgery (risk ratio 0.65; 95%CI, 0.44-0.97; p = 0.04; I2 = 56%. Of the two common types of wound protectors double ring devices were found to exhibit a greater protective effect (risk ratio 0.29; 95%CI, 0.15-0.55 than single-ring devices (risk ratio 0.71; 95%CI, 0.54-0.92, but this might largely be due to the lower quality of available data for double-ring devices. Exploratory subgroup analyses for the degree of contamination showed a larger protective effect in contaminated cases (0.44; 95%CI, 0.28-0.67; p = 0.0002, I2 = 23% than in clean-contaminated surgeries (0.72, 95%CI, 0.57-0.91; p = 0.005; I2 = 46% and a strong effect on the reduction of superficial surgical site infections (risk ratio 0.45; 95%CI, 0.24-0.82; p = 0.001; I2 = 72%.Wound edge protectors significantly reduce the rate of surgical site infections in open abdominal surgery.

Full Text Available A cirurgia abdominal alta está associada a um risco elevado de complicações pulmonares que podem ser reduzidas pelo uso criterioso de manobras terapêuticas visando a expansão pulmonar. 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. The purpose here was to compare two respiratory incentive techniques on recovery of thoracic-abdominal dynamics in patients having undergone upper abdominal surgery. Sixteen patients in such condition were randomly divided into group 1 (n=10, who did respiratory training

Full Text Available Gossypiboma is a mass lesion at the site of surgery due to a forgotten surgical sponge. Forgotten foreign bodies are mostly retained in the abdominal cavity but there are some cases in the thorax, cranium, breast, and an extremity. Gossypiboma should be considered, especially by radiologists, in patients with a history of surgery, who present with non-specific symptoms and abdominal mass. In this report, we describe the case of a female patient who presented with non-specific abdominal discomfort and fever about six months after open cholecystectomy.

Full Text Available Background and Objective: Pain is a common postoperative complaint, and the use of analgesics before surgical trauma can effectively prevent peripheral and central sensitization. We aimed to compare the preemptive effects of ibuprofen and celecoxib on post-operative pain after lower abdominal surgery in addicted patients. Materials and Methods: In this clinical trial, after obtaining informed consent, 114 addicted patients undergoing lower abdominal surgery were randomly divided into three groups of 38. The first group was given a 200 mg dose of oral celecoxib, 400 mg of ibuprofen was orally administered to patients in the second group, and the third group was given redsop hcrats as placebo by a nurse who prepared these drugs in the form of capsules. Postoperative pain was assessed by using a 10-cm ruler as the visual analogue scale at intervals of 1 and 6 hours after surgery. Postoperative opioid consumption was recorded in those periods. The obtained data were analyzed using the appropriate statistical tests in SPSS software. Results: Mean pain scores at 1 hour after surgery were not significantly different across the three groups, whereas at 6 hours after surgery, pain scores were significantly lower in the ibuprofen and celecoxib groups in comparison to the placebo group (P=0.001 and P=0.005, respectively. Postoperative nausea and vomiting was not significantly different among the three groups. Conclusion: Despite the significant difference in mean pain scores among the study groups, the opioid consumption doses were not significantly different among the groups. Thus, the preemptive prescription of nonsteroidal anti-inflammatory drugs in addicted patient does not have any noticeable effects.

To evaluate the imaging findings of abdominal wall endometriosis. In seven of 17 patients with surgically proven endometriosis of the abdominal wall, we retrospectively reviewed the findings of radiologic studies such as abdominal US (n=3), CT (n=4), and MRI (n=1). One patient under went more than one type of imaging, apparently. The surgical history of the seven, and their symptoms and preoperative diagnosis were reviewed, and the size, location, margin and nature of the mass, and the contrast enhancement patterns observed at radiologic studies, were assessed. The chief symptoms were palpable abdominal wall mass (n=5) and lower abdominal pain (n=2) around a surgical scar. Previous surgery included cesarean section (n=5), cesarean section with oophorectomy (n=1) and appendectomy (n=1). Masses were located in the subcutaneous fat layer (n=5) or rectus abdominis muscle (n=2), and their maximum diameter was 2.6 cm. Imaging findings, which correlated closely with the pathologic findings, included a well (n=5) or poorly marginated (n=2) solid mass, with a focal cystic area apparent in two cases. Although imaging findings of abdominal wall endometriosis may not be specific for diagnosis, the presence of a solid abdominal mass in female patients of reproductive age with a history of surgery is a diagnostic pointer.

Prophylactic continuous positive airway pressure (CPAP) can prevent pulmonary adverse events following upper abdominal surgeries. The present meta-regression evaluates and quantifies the effect of degree/duration of (CPAP) on the incidence of postoperative pulmonary events. Medical databases were searched for randomized controlled trials involving adult patients, comparing the outcome in those receiving prophylactic postoperative CPAP versus no CPAP, undergoing high-risk abdominal surgeries. Our meta-analysis evaluated the relationship between the postoperative pulmonary complications and the use of CPAP. Furthermore, meta-regression was used to quantify the effect of cumulative duration and degree of CPAP on the measured outcomes. Seventy-three potentially relevant studies were identified, of which 11 had appropriate data, allowing us to compare a total of 362 and 363 patients in CPAP and control groups, respectively. Qualitatively, Odds ratio for CPAP showed protective effect for pneumonia [0.39 (0.19-0.78)], atelectasis [0.51 (0.32-0.80)] and pulmonary complications [0.37 (0.24-0.56)] with zero heterogeneity. For prevention of pulmonary complications, odds ratio was better for continuous than intermittent CPAP. Meta-regression demonstrated a positive correlation between the degree of CPAP and the incidence of pneumonia with a regression coefficient of +0.61 (95 % CI 0.02-1.21, P = 0.048, τ (2) = 0.078, r (2) = 7.87 %). Overall, adverse effects were similar with or without the use of CPAP. Prophylactic postoperative use of continuous CPAP significantly reduces the incidence of postoperative pneumonia, atelectasis and pulmonary complications in patients undergoing high-risk abdominal surgeries. Quantitatively, increasing the CPAP levels does not necessarily enhance the protective effect against pneumonia. Instead, protective effect diminishes with increasing degree of CPAP.

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)

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.

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

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.

Abnormal pretreatment flexion-relaxation in chronic disabling occupational lumbar spinal disorder patients has been shown to improve with functional restoration rehabilitation. Little is known about the effects of prior lumbar surgeries on flexion-relaxation and its responsiveness to treatment. To quantify the effect of prior lumbar surgeries on the flexion-relaxation phenomenon and its responsiveness to rehabilitative treatment. A prospective cohort study of chronic disabling occupational lumbar spinal disorder patients, including those with and without prior lumbar spinal surgeries. A sample of 126 chronic disabling occupational lumbar spinal disorder patients with prior work-related injuries entered an interdisciplinary functional restoration program and agreed to enroll in this study. Fifty-seven patients had undergone surgical decompression or discectomy (n=32) or lumbar fusion (n=25), and the rest had no history of prior injury-related spine surgery (n=69). At post-treatment, 116 patients were reevaluated, including those with prior decompressions or discectomies (n=30), lumbar fusions (n=21), and no surgery (n=65). A comparison group of 30 pain-free control subjects was tested with an identical assessment protocol, and compared with post-rehabilitation outcomes. Mean surface electromyography (SEMG) at maximum voluntary flexion; subject achievement of flexion-relaxation (SEMG≤3.5 μV); gross lumbar, true lumbar, and pelvic flexion ROM; and a pain visual analog scale self-report during forward bending task. Identical measures were obtained at pretreatment and post-treatment. Patients entered an interdisciplinary functional restoration program, including a quantitatively directed, medically supervised exercise process and a multimodal psychosocial disability management component. The functional restoration program was accompanied by a SEMG-assisted stretching training program, designed to teach relaxation of the lumbar musculature during end-range flexion

Mortality from abdominal abscesses ranges from 30% in treated cases up to 80% to 100% in patients with undrained or nonoperated abscesses. Various computed tomographic (CT) imaging features have been suggested to indicate infection of postoperative abdominal fluid collections; however, features are nonspecific and substantial overlap between infected and noninfected collections exists. The purpose of this study was to develop and validate a scoring system on the basis of CT imaging findings as well as laboratory and clinical parameters for distinguishing infected from noninfected abdominal fluid collections after surgery. The score developmental cohort included 100 consecutive patients (69 men, 31 women; mean age, 58 ± 17 years) who underwent portal-venous phase CT within 24 hours before CT-guided intervention of postoperative abdominal fluid collections. Imaging features included attenuation (Hounsfield unit [HU]), volume, wall enhancement and thickness, fat stranding, as well as entrapped gas of fluid collections. Laboratory and clinical parameters included diabetes, intake of immunosuppressive drugs, body temperature, C-reactive protein, and leukocyte blood cell count. The score was validated in a separate cohort of 30 consecutive patients (17 men, 13 women; mean age, 51 ± 15 years) with postoperative abdominal fluid collections. Microbiologic analysis from fluid samples served as the standard of reference. Diabetes, body temperature, C-reactive protein, attenuation of the fluid collection (in HUs), wall enhancement and thickness of the wall, adjacent fat stranding, as well as entrapped gas within the fluid collection were significantly different between infected and noninfected collections (P collection (in HUs), as well as entrapped gas as significant independent predictors of infection (P collection, ≥ 20 HU: 4 points; entrapped gas: 3 points). The model was well calibrated (Hosmer-Lemeshow test, P = 0.36). In the validation cohort, scores of 2 or lower

Full Text Available Context: Supraglottic airway devices have been used as an alternative to tracheal intubation during laparoscopic surgery. Aims: The study was designed to compare the efficacy of Streamlined Liner of the Pharynx Airway (SLIPA for positive pressure ventilation and postoperative complications with the Laryngeal Mask Airway ProSeal (PLMA for patients undergoing lower abdominal laparoscopies under general anesthesia with controlled ventilation. Settings and Design: Prospective, crossover randomized controlled trial performed on patients undergoing lower abdominal laparoscopic surgeries. Methods: A total of 120 patients undergoing lower abdominal laparoscopic surgeries were randomly allocated into two equal groups; PLMA and SLIPA groups. Number of intubation attempts, insertion time, ease of insertion, and fiberoptic bronchoscopic view were recorded. Lung mechanics data were collected 5 minutes after securing the airway, then after abdominal insufflation. Blood traces and regurgitation were checked for; postoperative sore throat and other complications were recorded. Statistical Analysis: Arithmetic mean and standard deviation values were calculated and statistical analyses were performed for each group. Independent sample t-test was used to compare continuous variables exhibiting normal distribution, and Chi-squared test for noncontinuous variables. P value <0.05 was considered significant. Results: Insertion time, first insertion success rate, and ease of insertion were comparable in both groups. Fiberoptic bronchoscopic view was significantly better and epiglottic downfolding was significantly lower in SLIPA group. Sealing pressure and lung mechanics were similar. Gastric distension was not observed in both groups. Postoperative sore throat was significantly higher in PACU in PLMA group. Blood traces on the device were significantly more in SLIPA group. Conclusions: SLIPA can be used as a useful alternative to PLMA in patients undergoing lower

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.

Full Text Available Abstract Background Post-operative pulmonary complications add to the morbidity and mortality of surgical patients, in particular after general anesthesia >2 hours for abdominal surgery. Whether a protective mechanical ventilation strategy with higher levels of positive end-expiratory pressure (PEEP and repeated recruitment maneuvers; the "open lung strategy", protects against post-operative pulmonary complications is uncertain. The present study aims at comparing a protective mechanical ventilation strategy with a conventional mechanical ventilation strategy during general anesthesia for abdominal non-laparoscopic surgery. Methods The PROtective Ventilation using HIgh versus LOw positive end-expiratory pressure ("PROVHILO" trial is a worldwide investigator-initiated multicenter randomized controlled two-arm study. Nine hundred patients scheduled for non-laparoscopic abdominal surgery at high or intermediate risk for post-operative pulmonary complications are randomized to mechanical ventilation with the level of PEEP at 12 cmH2O with recruitment maneuvers (the lung-protective strategy or mechanical ventilation with the level of PEEP at maximum 2 cmH2O without recruitment maneuvers (the conventional strategy. The primary endpoint is any post-operative pulmonary complication. Discussion The PROVHILO trial is the first randomized controlled trial powered to investigate whether an open lung mechanical ventilation strategy in short-term mechanical ventilation prevents against postoperative pulmonary complications.

The PerfecTemp is an underbody resistive warming system that combines servocontrolled underbody warming with viscoelastic foam pressure relief. Clinical efficacy of the system has yet to be formally evaluated. We therefore tested the hypothesis that intraoperative distal esophageal (core) temperatures with the PerfecTemp (underbody resistive) warming system are noninferior to upper-body forced-air warming in patients undergoing major open abdominal surgery under general anesthesia. Adults scheduled for elective major open abdominal surgery (liver, pancreas, gynecological, and colorectal surgery) under general anesthesia were enrolled at 2 centers. Patients were randomly assigned to underbody resistive or forced-air warming. Resistive heating started when patients were transferred to the operating room table; forced-air warming started after patients were draped. The primary outcome was noninferiority of intraoperative time-weighted average core temperature, adjusted for baseline characteristics and using a buffer of 0.5°C. Thirty-six patients were randomly assigned to underbody resistive heating and 34 to forced-air warming. Baseline and surgical characteristics were generally similar. We had sufficient evidence (P=0.018) to conclude that underbody resistive warming is not worse than (i.e., noninferior to) upper-body forced-air warming in the time-weighted average intraoperative temperature, with a mean difference of -0.12°C [95% confidence interval (CI) -0.37 to 0.14]. Core temperatures at the end of surgery averaged 36.3°C [95% CI 36 to 36.5] in the resistive warming patients and 36.6°C [95% CI 36.4 to 36.8] in those assigned to forced-air warming for a mean difference of -0.34°C [95% CI -0.69 to 0.01]. Mean intraoperative time-weighted average core temperatures were no different, and significantly noninferior, with underbody resistive heating in comparison with upper-body forced-air warming. Underbody resistive heating may be an alternative to forced

The aim of this study was to predict acute postsurgical pain and coping with pain following surgery based on preoperative time perspectives. Time perspective is a basic dimension of psychological time. It is a tendency to focus on a particular time area: the past, the present and the future. Seventy-six patients completed measures of time perspective and pain 24 h before abdominal surgery. During the 3 days after surgery, measures of pain and coping with pain were completed. We performed hierarchical regression analyses to identify predictors of acute postsurgical pain and how patients cope with it. These analyses suggested that a preoperative past-negative time perspective can be a predictor of postoperative pain level and catastrophizing after surgery. The findings of our study indicate the importance of time perspective, especially the past perspective, in dealing with postoperative pain. Our research indicates that a preoperative past-negative time perspective is a significant predictor of acute postsurgical pain intensity and the strongest predictor of pain catastrophizing. © 2016 European Pain Federation - EFIC®.

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 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.

Full Text Available Early diagnosis and treatment of complications after major abdominal surgery can decrease associated morbidity and mortality. Postoperative CRP levels have shown a strong correlation with complications. Aim of this systematic review and pooled-analysis was to assess postoperative values of CRP as a marker for major complications and construct a prediction model.A systematic review was performed for CRP levels as a predictor for complications after major abdominal surgery (MAS. Raw data was obtained from seven studies, including 1427 patients. A logit regression model assessed the probability of major complications as a function of CRP levels on the third postoperative day. Two practical cut-offs are proposed: an optimal cut-off for safe discharge in a fast track protocol and another for early identification of patients with increased risk for major complications.A prediction model was calculated for major complications as a function of CRP levels on the third postoperative day. Based on the model several cut-offs for CRP are proposed. For instance, a two cut-off system may be applied, consisting of a safe discharge criterion with CRP levels below 75 mg/L, with a negative predictive value of 97.2%. A second cut-off is set at 215 mg/L (probability 20% and serves as a predictor of complications, indicating additional CT-scan imaging.The present study provides insight in the interpretation of CRP levels after major abdominal surgery, proposing a prediction model for major complications as a function of CRP on postoperative day 3. Cut-offs for CRP may be implemented for safe early-discharge in a fast-track protocol and, secondly as a threshold for additional examinations, such as CT-scan imaging, even in absence of clinical signs, to confirm or exclude major complications. The prediction model allows for setting a cut-off at the discretion of individual surgeons or surgical departments.

Previous investigations of short-term outcomes after preoperative exposure to biological therapy in inflammatory bowel disease (IBD) were conflicting. The authors aimed to assess postoperative outcomes in patients who underwent abdominal surgery with recent exposure to anti-tumour necrosis factor therapy. A retrospective case-control study with detailed matching was performed for subjects with IBD with and without exposure to biologics within 180 days of abdominal surgery. Postoperative outcomes were compared between the groups. 473 procedures were reviewed consisting of 195 patients with exposure to biologics and 278 matched controls. There were no significant differences in most postoperative outcomes such as: length of stay, fever (≥ 38.5°C), urinary tract infection, pneumonia, bacteraemia, readmission, reoperations and mortality. On univariate analysis, procedures on biologics had more wound infections compared with controls (19% vs 11%; p=0.008), but this was not significant in multivariate analysis. Concomitant therapy with biologics and thiopurines was associated with increased frequencies of urinary tract infections (p=0.0007) and wound infections (p=0.0045). Operations performed ≤ 14 days from last biologic dose had similar rates of infections and other outcomes when compared with those performed within 15-30 days or 31-180 days. Patients with detectable preoperative infliximab levels had similar rates of wound infection compared with those with undetectable levels (3/10 vs 0/9; p=0.21). Preoperative treatment with TNF-α antagonists in patients with IBD is not associated with most early postoperative complications. A shorter time interval from last biological dose is not associated with increased postoperative complications. In most cases, surgery should not be delayed, and appropriate biological therapy may be continued perioperatively.

Hand-assisted laparoscopic surgery and its applications in gynecology

Directory of Open Access Journals (Sweden)

Yueqian Wu

2016-02-01

Full Text Available Laparoscopic surgery has been used extensively since it was first applied in the 1980s. The advantages are generally accepted and include less pain, smaller incisions, faster recovery, and shorter hospital stays. However, several limitations associated with standard laparoscopic surgery (SLS have become apparent and include the loss of tactile sensation, problems with the removal of bulky and intact specimens, and the restriction of visualization of the entire operating field. These problems with SLS helped to inspire the development of laparoscopically assisted surgery followed by hand-assisted laparoscopic surgery (HALS. In a hand-assisted laparoscopic procedure, an incision is made in the patient’s abdomen. Then, a uniquely designed appliance is introduced into the abdominal cavity through the incision to maintain pneumoperitoneum. With the inserting hand, surgeons can provide manual exposure, traction, palpation, and dissection because of the feedback of tactile sensation. HALS has gained acceptance for a wide range of abdominal procedures in general surgery and urology and is now feasible for complicated surgeries such as splenectomy, nephroureterectomy, and colectomy. It has been demonstrated in numerous specialties that HALS is a safe and efficacious technique that combines the benefits of laparoscopy with the advantages of a conventional laparotomy. Standard laparoscopic surgery also has limitations in gynecological surgery. A patient may have high risks with conventional laparoscopic surgery when she has deep invasive endometriosis, multiple or massive myoma, or dense pelvic adhesions from prior surgery. HALS overcomes many of the aforementioned limitations, has less conversion to open surgery, and broadens the indications for minimally invasive surgery, not only for benign tumors but also for pelvic malignancies.

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.

Full Text Available  Background: Calcium (Ca+2 plays an important role in many biophysiological mechanisms .The present study was carried out to assess alterations in total serum calcium level before and after operations in consider to the type of anesthesia. Materials and Methods: This descriptive study was conducted on 74 women who candidate for gynecological abdominal operations during one year at Al-zahra maternity Hospital in Rasht, Iran. The patients underwent General Anesthesia (GA (N=37 or Spinal Anesthesia (SA (N=37 randomly. Blood samples (2 cc, were obtained an hour before the anesthesia and two hours after that. The blood samples had been sent to the laboratory for analyzing .Total serum calcium level, magnesium (Mg and albumin level were measured by photometric methods. Inferential statistic was analyzed with the Vilkson non-parametric and Pearson's correlation test. P-values less than 0.05 have been considered as significant different. Results: There was a significant trend to decrease in calcium levels after all gynecological abdominal operations, but there was a significant correlation between General anesthesia (GA and reduction of serum calcium level (p=0.026 . Therefore, General Anesthesia (GA is accompanied by more calcium reduction than Spinal Anesthesia (SA. Conclusion: Serum Calcium levels tend to decrease after all gynecological abdominal surgeries, but General Anesthesia (GA is accompanied by more calcium reduction than Spinal one. It needs to further specific studies, to illustrate association between different methods of anesthesia and Ca+2 changes.

Anthropometric measurements can be used to define pediatric malnutrition. Our study aims to: (1) characterize the preoperative nutritional status of children undergoing abdominal or thoracic surgery, and (2) describe the associations between WHO-defined acute (stunting) and chronic (wasting) undernutrition (Z-scores +2) with 30-day postoperative outcomes. We queried the Pediatric NSQIP Participant Use File and extracted data on patients' age 29days to 18years who underwent abdominal or thoracic procedures. Normalized anthropometric measures were calculated, including weight-for-height for nutritional outlier status as an independent predictor of postoperative outcome. 23,714 children (88% ≥2y) were evaluated. 4272 (18%) were obese, while 2640 (11.1%) and 904 (3.8%) were stunted and wasted, respectively, after controlling for gender, ASA/procedure/wound classification, preoperative steroid use, need for preoperative nutritional support, and obese children had higher odds of SSIs (OR 1.29, 95% CI 1.1-1.5, p=0.001), while stunted children were at increased risk of any 30-day postoperative complication (OR 1.16, 95% CI 1.0-1.3, p=0.036). Children who are stunted or obese are at increased risk of adverse outcome after abdominal or thoracic surgery. III. Copyright © 2018 Elsevier Inc. All rights reserved.

A randomized controlled trial to compare pregabalin with gabapentin for postoperative pain in abdominal hysterectomy

Directory of Open Access Journals (Sweden)

Anju Ghai

2011-01-01

Full Text Available Background: Pregabalin is a potent ligand for alpha-2-delta subunit of voltage-gated calcium channels in the central nervous system, which exhibits potent anticonvulsant, analgesic and anxiolytic activity. The pharmacological activity of pregabalin is similar to that of gabapentin and shows possible advantages. Although it shows analgesic efficacy against neuropathic pain, very limited evidence supports its postoperative analgesic efficacy. We investigated its analgesic efficacy in patients experiencing acute pain after abdominal hysterectomy and compared it with gabapentin and placebo. Methods: A randomized, double-blind, placebo-controlled study was conducted in 90 women undergoing abdominal hysterectomy who were anaesthetized in a standardized fashion. Patients received 300 mg pregabalin, 900 mg gabapentin or placebo, 1-2 hours prior to surgery. Postoperative analgesia was administered at visual analogue scale (VAS ≥3. The primary outcome was analgesic consumption over 24 hours and patients were followed for pain scores, time to rescue analgesia and side effects as secondary outcomes. Results: The diclofenac consumption was statistically significant between pregabalin and control groups, and gabapentin and control groups; however, pregabalin and gabapentin groups were comparable. Moreover, the consumption of tramadol was statistically significant among all the groups. Patients in pregabalin and gabapentin groups had lower pain scores in the initial hour of recovery. However, pain scores were subsequently similar in all the groups. Time to first request for analgesia was longer in pregabalin group followed by gabapentin and control groups. Conclusion: A single dose of 300 mg pregabalin given 1-2 hours prior to surgery is superior to 900 mg gabapentin and placebo after abdominal hysterectomy. Both the drugs are better than placebo.

The prognosis of ovarian cancers, which are frequently diagnosed at a late stage, can probably be improved by whole abdominal radiotherapy. 45 patients in Lyon and 8 patients in Montelimar (7 stage I or C, 10 stage II and 36 stage III) were treated by whole abdominal radiotherapy, generally after 6 courses of chemotherapy (46 cases). The overall 5-year survival of this group of patients was 48% (Kaplan-Meier method). When the patients treated by complete resection at 1st look surgery (19 cases) are compared with those in whom 1st look surgery was incomplete (34 cases), the actuarial survival was 83% versus 27%. This study demonstrates that whole abdominal radiotherapy is feasible without any serious long-term complications after two operations and 6 courses of chemotherapy. These encouraging results need to be confirmed by randomized prospective studies [fr

Coronary artery disease (CAD) was evaluated by noninvasive examination in abdominal aortic aneurysm (AAA) patients. A simultaneous operation or a 2-staged operation was performed depending on the seriousness of the condition when both diseases were combined. A total of 36 patients underwent elective repair of AAA between 1996 and 2001. Coronary angiography (CAG) was performed only in patients with suspected CAD by dipyridamole myocardial scintigraphy. Significant CAD was found in 8 patients. Simultaneous operation was performed in 4 patients, and off-pump coronary artery bypass grafting (OPCAB) was performed in all cases of simultaneous operation. In 4 patients receiving 2-staged operations, 1 standard coronary artery bypass grafting (CABG), 1 OPCAB and 2 percutaneous transluminal coronary angioplasties (PTCA) were performed prior to AAA surgery. Twenty-eight patients underwent only AAA operation. Though there were no incidents of perioperative myocardial infarction or cardiac related deaths in this group, 2 patients died due to other causes (hemorrhage and duodenal perforation). In the 8 patients associated with CAD, 1 patient died of myonephrotic metabolic syndrome (MNMS) after simultaneous operation. The other 7 patients revived their social function soon of the discharge. Dipyridamole cardiac scintigraphy was considered to be an effective examination for evaluation of CAD in AAA patients. There was no need to perform CAG in all AAA patients. The policy of choosing simultaneous operation or 2-staged operation according to the seriousness of the 2 diseases seemed to be appropriate. (author)

Objectives The relationship between preoperative medical consultations and postoperative complications has not been extensively studied. Thus, we investigated the impact of preoperative consultation on postoperative morbidity following elective abdominal aortic aneurysm repair. Methods A retrospective review was conducted on 469 patients (mean age 72 years, 20% female) who underwent elective abdominal aortic aneurysm repair from June 2007 to July 2014. Data elements included detailed medical history, preoperative cardiology consultation, and postoperative complications. Primary outcomes included 30-day morbidity, consult-specific morbidity, and mortality. A bivariate probit regression model accounting for the endogeneity of binary preoperative medical consult and patient variability was estimated with a maximum likelihood function. Results Eighty patients had preoperative medical consults (85% cardiology); thus, our analysis focuses on the effect of cardiac-related preoperative consults. Hyperlipidemia, increased aneurysm size, and increased revised cardiac risk index increased likelihood of referral to cardiology preoperatively. Surgery type (endovascular versus open repair) was not significant in development of postoperative complications when controlling for revised cardiac risk index ( p = 0.295). After controlling for patient comorbidities, there was no difference in postoperative cardiac-related complications between patients who did and did not undergo cardiology consultation preoperatively ( p = 0.386). Conclusions When controlling for patient disease severity using revised cardiac risk index risk stratification, preoperative cardiology consultation is not associated with postoperative cardiac morbidity.

Abstract Objective To assess the efficacy of a single preoperative physiotherapy session to reduce postoperative pulmonary complications (PPCs) after upper abdominal surgery. Design Prospective, pragmatic, multicentre, patient and assessor blinded, parallel group, randomised placebo controlled superiority trial. Setting Multidisciplinary preadmission clinics at three tertiary public hospitals in Australia and New Zealand. Participants 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. Interventions 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. Main outcome measures 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. Results 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

Plasma osmotic changes during major abdominal surgery.

Fluid balance across the capillary membrane is maintained normally by a balance of hydrostatic and colloid osmotic pressures (COP). In 12 patients having major intra-abdominal procedures, the COP was followed during the operative and immediate postoperative periods. The patients' intraoperative fluid management consisted of replacing shed blood with blood and following Shires' concept of crystalloid replacement. Significant decreases in COP to approximately two thirds of the initial value occurred in patients having intra-abdominal procedures versus only a 10 percent decrease in those having peripheral procedures (greater than .001). As a result of this decrease in COP, the balance between hydrostatic and colloid osmotic pressures is lost and risk of pulmonary intersitial edema is increased.

Thirty-six h following surgery the animals were killed and blood taken for full blood count, total protein, albumin, α, β and γ globulin fractions on serum electrophoresis, complement C3 and transferrin levels. Danazol increased the α1, α2 and β1 globulin serum protein fractions in comparison with no surgery and CLP alone groups. These results indicate that danazol increases plasma acute phase proteins, as measured by electrophoresis, in this model of intra-abdominal sepsis.

Trauma, especially chest and abdominal trauma are increasing due to the growing number of vehicles on the roads, which leads to an increased incidence of road accidents. Urbanization, industrialization and additional problems are the other associated factors which accelerate this phenomenon. A better understanding of the etiology and pattern of such injuries can help to improve the management and ultimate the outcomes of these patients. This study aimed to evaluate the patients with chest and abdominal trauma hospitalized in the surgery ward of Poursina teaching hospital, Guilan, Iran. In this cross-sectional study, the data of all chest and abdominal trauma patients hospitalized in the surgery ward of Poursina teaching hospital were collected from March 2011 to March 2012. Information about age, gender, injured areas, type of injury (penetrating or blunt), etiology of the injury, accident location (urban or rural) and patients' discharge outcomes were collected by a questionnaire. In total, 211 patients with a mean age of 34.1 ± 1.68 years was entered into the study. The most common cause of trauma was traffic accidents (51.7%). Among patients with chest trauma, 45 cases (35.4%) had penetrating injuries and 82 cases (64.6%) blunt lesions. The prevalence of chest injuries was 35.5% and rib fractures 26.5%. In chest injuries, the prevalence of hemothorax was 65.3%, pneumothorax 2.7%, lung contusion 4% and emphysema 1.3%, respectively. There were 24 cases (27.9%) with abdominal trauma which had penetrating lesions and 62 cases (72.1%) with blunt lesions. The most common lesions in patients with penetrating abdominal injuries were spleen (24.2%) and liver (12.1%) lesions. The outcomes of the patients were as follow: 95.7% recovery and 4.3% death. The majority of deaths were observed among road traffic victims (77.7%). Considering the fact that road-related accidents are quite predictable and controllable; therefore, the quality promotion of traumatic patients' care

The laparoscopic approach in colorectal complications is controversial because of its difficulty. However, it has been proven that it can provide advantages over open surgery. The aim of this study is to compare laparoscopic approach in reoperations for complications after colorectal surgery with the open approach taking into account the severity of the patient prior to reoperation. Patients who underwent laparoscopic colorectal surgery from January 2006 to December 2015 were retrospectively reviewed. Patients requiring urgent surgical procedures for complications in the postoperative period were divided in two groups: laparoscopic surgery (LS) and open surgery (OS). To control clinical severity prior to reoperation, The Mannheim Peritonitis Index (MPI) was calculated. A total of 763 patients were studied, 40 required urgent surgery (24 OS/16 LS). More ileostomies were performed in the LS group (68.7% vs. 29.2%) and more colostomies in the OS group (37.5% vs. 6.2%), pstart of oral tolerance and less surgical wound infection (pstart of oral tolerance and a lower abdominal wall complication rate in patients with low severity index.

During the last four years 102 patients with abdominal trauma were examined by CT for preoperative evaluation in our hospital. In 35 patients (34 %), the CT scans revealed no abnormal findings. They were all managed conservatively except for one case of perforated small bowel. In 67 patients (66 %) CT revealed evidences of substantial abdominal or retroperitoneal trauma. In 30 of them CT findings were confirmed by surgery. Hepatic injury is usually easily recognized by CT. CT is also useful for the detection of renal or splenic injuries. The majority of those parenchymatous organ injuries were successfully managed with conservative therapy, despite apparent traumatic lesions revealed by CT. Repeat CT scans is proved to be very useful to follow the changes of these traumatic lesions. In conclusion, application of abdominal CT is extremely useful for the initial decision making in treatment of patients with abdominal trauma and for the follow-up observation of injured lesions.

Primary or neoadjuvant chemotherapy prior to definitive local therapy has potential advantages for locally advanced cervix cancer. It can down stage a cancer and allow definitive local therapy to be technically possible (surgery), or potentially more effective (radiotherapy). It can also eradicate subclinical systemic metastases. This report reviews a single institution's experience of neoadjuvant chemotherapy prior to definitive local therapy for cervix cancer over a 13-year period. One hundred and six patients were treated with this intent. The patients were analysed for their response to chemotherapy, treatment received, survival, relapse and toxicity. The chemotherapy was feasible and the majority of patients had a complete or partial response (58.5%). Eight patients did not proceed to local treatment. Forty-six patients had definitive surgery and 52 had definitive radiotherapy. The 5-year overall survival was 27% and the majority of patients died with disease. The first site of relapse was usually in the pelvis (46.2%). Late complications that required ongoing medical therapy (n = 6) or surgical intervention (n = 2) were recorded in eight patients (7.5%). On univariate analysis stage (P= 0.04), tumour size (P = 0.01), lymph node status (P=0.003), response to chemotherapy (P = 0.045) and treatment (P = 0.003) were all significant predictors of survival. On multivariate analysis, tumour size (P < 0.0001) and nodal status (P = 0.02) were significant predictors of survival. Despite the impressive responses to chemotherapy of advanced cervix cancer, there is evidence from randomized trials that it does not improve or compromise survival prior to radiotherapy. As its role prior to surgery remains unclear, it should not be used in this setting outside a prospective randomized trial. Copyright (2001) Blackwell Science Pty Ltd

A previously healthy 3-week-old boy presented with 5 hours of marked fussiness, abdominal distention, and poor feeding. He was afebrile and well perfused. His examination was remarkable for localized abdominal tenderness and distention. He was referred to the emergency department in which an abdominal radiograph revealed gaseous distention of the bowel with a paucity of gas in the pelvis. Complete blood cell count and urinalysis were unremarkable. His ongoing fussiness and abnormal physical examination prompted consultation with surgery and radiology. Our combined efforts ultimately established an unexpected diagnosis. Copyright © 2017 by the American Academy of Pediatrics.

This study aims to determine the long-term prognostic value of coronary CT angiography (CCTA) prior to bariatric surgery in severely obese patients with a body mass index (BMI) ≥35 kg/m 2 . Seventy consecutive patients undergoing cardiac CT for coronary assessment prior to bariatric surgery were prospectively included. Images were analysed for the presence of coronary calcification and for non-obstructive (50% stenosis) coronary artery disease (CAD). A median clinical follow-up of 6.1 years in 54 patients was obtained for major adverse cardiovascular events (MACEs), defined as death, non-fatal myocardial infarction or coronary revascularisation. Weight loss and BMI decrease following bariatric surgery were recorded. The median BMI prior to surgery was 46.9 kg/m 2 . The median percentage of excess BMI loss after surgery was 75%. CT showed coronary calcification in 26 (48%) patients, whereas 28 (52%) patients had no calcification. CCTA revealed normal coronaries in 47 (87%) and non-obstructive CAD in 7 (13%) patients. No obstructive CAD was found. All patients successfully underwent bariatric surgery, and no MACE occurred neither perioperatively nor in the follow-up period. The negative predictive value of CCTA was 100% (95% confidence interval of 90.1-100.0%). In severely obese patients, the absence of obstructive CAD in cardiac CT prior to bariatric surgery with subsequently marked weight reduction has strong long-term prognostic implications for ruling out major adverse cardiac events in the postoperative period.

This study comprises 25 cases of blunt abdominal trauma proved by surgery. It is concluded that visceral damage by blunt abdominal trauma may be suspected, but can not be satisfactorily diagnosed upon a single plane abdominal roentgenologic examination with clinical support. Contrary to some reports in the literature, rupture of the hallow, viscus is more susceptible than solid organ and ileum is more than jejunum. It is a useful roentgenologic sign denoting distension and small cresent air shadow in the duodenal sweep of the damaged pancreas.

Full Text Available Appendecitis is one of the most frequent surgeries. Inflammation of appendix may be due to variable causes such as fecalit, hypertrophy of Peyer’s plaques, seeds of fruits and parasites. In this study we presented an uncommon type of appendicitis which occurred after abdominal blunt trauma. In this article three children present who involved acute appendicitis after blunt abdominal trauma. These patients were 2 boys (5 and 6-year-old and one girl (8-year-old who after blunt abdominal trauma admitted to the hospital with abdominal pain and symptoms of acute abdomen and appendectomy had been done for them.Trauma can induce intramural hematoma at appendix process and may cause appendicitis. Therefore, physicians should be aware of appendicitis after blunt abdominal trauma

Injury to the abdomen can be blunt or penetrating. Abdominal injury can damage internal organs such as the liver, spleen, kidneys, intestine, and large blood vessels. There are controversies about the best approach to manage abdominal injuries. To assess the effects of surgical and non-surgical interventions in the management of abdominal trauma in a haemodynamically stable and non-peritonitic abdomen. We searched the Cochrane Injuries Group's Specialised Register, The Cochrane Library, Ovid MEDLINE(R), Ovid MEDLINE(R) In-Process & Other Non-Indexed Citations, Ovid MEDLINE(R) Daily and Ovid OLDMEDLINE(R), EMBASE Classic+EMBASE (Ovid), ISI WOS (SCI-EXPANDED, SSCI, CPCI-S & CPSI-SSH), CINAHL Plus (EBSCO), and clinical trials registers, and screened reference lists. We ran the most recent search on 17 September 2015. Randomised controlled trials of surgical interventions and non-surgical interventions involving people with abdominal injury who were haemodynamically stable with no signs of peritonitis. The abdominal injury could be blunt or penetrating. Two review authors independently applied the selection criteria. Data were extracted by two authors using a standard data extraction form, and are reported narratively. Two studies are included, which involved a total of 114 people with penetrating abdominal injuries. Both studies are at moderate risk of bias because the randomisation methods are not fully described, and the original study protocols are no longer available. The studies were undertaken in Finland between 1992 and 2002, by the same two researchers.In one study, 51 people were randomised to surgery or an observation protocol. None of the participants in the study died. Seven people had complications: 5 (18.5%) in the surgical group and 2 (8.3%) in the observation group; the difference was not statistically significant (P = 0.42; Fischer's exact). Among the 27 people who had surgery, 6 (22.2%) surgeries were negative laparotomies, and 15 (55.6%) were non

To provide clinical guidelines for the evaluation of women with stress urinary incontinence prior to primary anti-incontinence surgery. The modalities of evaluation range from basic pelvic examination through to the use of adjuncts including ultrasound and urodynamic testing. These guidelines provide a comprehensive approach to the preoperative evaluation of urinary incontinence to ensure that excessive evaluation is avoided without sacrificing diagnostic accuracy. Published opinions of experts, supplemented by evidence from clinical trials, where appropriate. The quality of the evidence is rated using the criteria described by the Canadian Task Force on the Periodic Health Examination. Comprehensive evaluation of women considering surgery to treat urinary incontinence is essential to rule out causes of incontinence that may not be amenable to surgical treatment. Simplifying the evaluation minimizes the discomfort and embarrassment potentially experienced by women. VALIDATION: These guidelines have been approved by the Urogynaecology Committee and the Executive and Council of The Society of Obstetricians and Gynaecologists of Canada. Copyright © 2018.

The Hospital Readmissions Reduction Program reduces payments to hospitals with excess readmissions for three common medical conditions and recently extended its readmission program to surgical patients. We sought to investigate readmission intensity as measured by readmission cost for high-risk surgeries and examine predictors of higher readmission costs. We used the Healthcare Cost and Utilization Project's State Inpatient Database to perform a retrospective cohort study of patients undergoing major chest (aortic valve replacement, coronary artery bypass grafting, lung resection) and major abdominal (abdominal aortic aneurysm repair [open approach], cystectomy, esophagectomy, pancreatectomy) surgery in 2009 and 2010. We fit a multivariable logistic regression model with generalized estimation equations to examine patient and index admission factors associated with readmission costs. The 30-d readmission rate was 16% for major chest and 22% for major abdominal surgery (P readmission costs for both chest (odds ratio [OR]: 1.99; 95% confidence interval [CI]: 1.60-2.48) and abdominal surgeries (OR: 1.86; 95% CI: 1.24-2.78). Comorbidities, length of stay, and receipt of blood or imaging was associated with higher readmission costs for chest surgery patients. Readmission >3 wk after discharge was associated with lower costs among abdominal surgery patients. Readmissions after high-risk surgery are common, affecting about one in six patients. Predictors of higher readmission costs differ among major chest and abdominal surgeries. Better identifying patients susceptible to higher readmission costs may inform future interventions to either reduce the intensity of these readmissions or eliminate them altogether.

Anesthesiologists play an important role in postoperative pain management. For analgesia after lower abdominal surgery, epidural analgesia and ultrasound-guided transversus abdominis plane (TAP) block are suitable options. The study aims to compare the analgesic efficacy of both techniques. Seventy-two patients undergoing lower abdominal surgery under spinal anesthesia were randomized to postoperatively receive lumbar epidural catheter (Group E) or ultrasound-guided TAP block (Group T) through intravenous cannulas placed bilaterally. Group E received 10 ml 0.125% bupivacaine stat and 10 ml 8 th hourly for 48 h. Group T received 20 ml 0.125% bupivacaine bilaterally stat and 20 ml bilaterally 8 th hourly for 48 h. Pain at rest and on coughing, total paracetamol and tramadol consumption were recorded. Analgesia at rest was comparable between the groups in the first 16 h. At 24 and 48 h, Group E had significantly better analgesia at rest ( P = 0.001 and 0.004 respectively). Patients in Group E had significantly higher number of patients with nil or mild pain on coughing at all times. Paracetamol consumption was comparable in both groups, but tramadol consumption was significantly higher in Group T at the end of 48 h ( P = 0.001). For lower abdominal surgeries, analgesia provided by intermittent boluses of 0.125% is comparable for first 16 h between epidural and TAP catheters. However, the quality of analgesia provided by the epidural catheter is superior to that provided by TAP catheters beyond that both at rest and on coughing with reduced opioid consumption.

Full Text Available Objective. This study aims to explore the usage of intraocular pressure measurements as the early indicator of the increase in intra-abdominal pressure. Methods. In this prospective study, 40 patients undergoing elective surgery were included. Patients were divided into four groups of 10 patients. The control group (Group C was not subjected to laparoscopic intervention. Laparoscopic surgery was, respectively, performed with an intra-abdominal pressure of 9, 12, and 15 mmHg in Groups L (low, M (medium, and H (high pressure. Intraocular pressure was measured binocularly in each patient at three different times (before, during, and end of surgery using a contact tonometer. Results. Patients’ gender, age, body mass index (BMI, American Society of Anesthesiology (ASA class, and operative times were not different among the groups. No complications occurred with either the surgery or measurement of intraocular pressure. Intubation was associated with a severe rise in IOP (P<0.05. An increase in intraocular pressure was seen in groups M and H (P<0.05. Conclusion. Intraocular pressure was increased in the groups with an intra-abdominal pressure of 12 mmHg or more. Measuring the intraocular pressure might be a useful method to estimate the intra-abdominal pressure. This trial is registered with NCT02319213.

The organ injury scale grading system proposed by the American Association for the Surgery of Trauma provides guidelines for operative versus nonoperative management in solid organ injuries; however, major shortcomings of the American Association for the Surgery of Trauma injury scale may become apparent with low-grade injuries, in which conservative management may fail. Nonoperative management of common intra-abdominal solid organ injuries relies increasingly on computed tomographic findings and other clinical factors, including patient age, presence of concurrent injuries, and serial clinical assessments. Familiarity with characteristic imaging features is essential for the prompt diagnosis and appropriate treatment of blunt abdominal trauma. In this pictorial essay, the spectrum of the American Association for the Surgery of Trauma organ injury scale grading system is illustrated, and a multidisciplinary management algorithm for common intra-abdominal solid organ injuries is proposed.

Malnutrition is a clinical condition of multifactorial etiologies and it is associated with several adverse outcomes. In high-income countries, malnutrition has been described as a determinant of delayed wound healing, surgical site infections and mortality in the postoperative period. There is limited information available regarding the outcome of surgery in malnourished patients in sub-Saharan Africa. A cross-sectional analytic study was carried out between March and August 2014 in the visceral surgery and the emergency departments of the Yaounde Central Hospital in Cameroon. All consecutive consenting preoperative and postoperative patients of abdominal surgical procedures were enrolled. Variables studied were: socio-demographic characteristics, medical and surgical past histories, nutritional survey, anthropometric parameters and serum albumin level in order to determine the nutritional risk index (or Buzby score). A total of 85 patients aged from 19 to 50 years with mean age of 34.4 ± 8 years were included. The most performed abdominal surgical procedure was appendectomy (30.6%). The prevalence of preoperative malnutrition according to the Buzby score was 39.1%. Mean postoperative weight lost was 2.9 ± 1.2 kg and mean decrease in postoperative serum albumin was 4.2 ± 0.2 g.

1994-01-01

Multiple injury patients with blunt abdominal trauma (n = 110) were examined by abdominal CT. An i.v., but not peroral, contrast medium was used, thereby eliminating the delay caused by administering peroral contrast medium and any subsequent delay in making the diagnoses and beginning operative treatment. Eighteen patients underwent emergency laparotomy after the initial CT examination. The preoperative CT findings were compared to the laparotomy findings. CT revealed all but one of the severe parenchymal organ lesions requiring surgery. The one liver laceration that went undetected had caused hemoperitoneum, which was diagnosed by CT. The bowel and mesenteric lesions presented as intra-abdominal blood, and the hemoperitoneum was discovered in every patient with these lesions. Fourteen patients also initially had positive abdominal CT findings; 10 of them underwent an additional abdominal CT within 3 days, but the repeat studies did not reveal any lesions in need of surgery. Omission of the oral contrast medium did not jeopardize making the essential diagnoses, but it did save time. (orig.)

Full Text Available Abstract Background A prerequisite for safe cataract surgery is an adequately dilated pupil. The authors conducted a trial to assess the efficacy (in terms of pupil diameter of a depot method of pre-operative pupil dilatation, as compared with repeated instillations of drops (which is time-consuming for the nursing staff and uncomfortable for the patient. Methods A prospective randomised masked trial was conducted comprising 130 patients with no significant ocular history undergoing elective clear corneal phacoemulsification. 65 patients had mydriatic drops (Tropicamide 1%, Phenylephrine 2.5%, Diclofenac sodium 0.1% instilled prior to surgery, 65 had a wick soaked in the same drop mixture placed in the inferior fornix. Horizontal pupil diameters were recorded on a millimetre scale immediately prior to surgery. Results There was no significant difference in pupil size between the two groups (p = 0.255, Student's t-test. Conclusion There was no significant difference between the mydriasis obtained with the depot system compared with conventional drop application. Use of a depot mydriatic delivery system appears to be a safe and efficient method of drug delivery.

CT of abdominal abscesses

International Nuclear Information System (INIS)

Korobkin, M.T.

1987-01-01

The imaging search for a suspected abdominal abscess is common in hospitalized patients, especially after recent abdominal surgery. This paper examines the role of CT in the detection, localization, and treatment of abdominal abscess. The accuracy, limitations, and technical aspects of CT in this clinical setting are discussed. The diagnosis of an abscess is based on the demonstration of a circumscribed abnormal fluid collection. Although percutaneous aspiration with gram stain and culture is usually indicated to differentiate abscess from other fluid collections, the CT-based detection of extraluminal gas bubbles makes the diagnosis of an abscess highly likely. CT is compared with conventional radiographic studies, US, and radio-nuclide imaging. Specific CT and clinical features of abscesses in the following sites are emphasized: subphrenic space, liver, pancreas, kidneys, psoas muscle, appendix, and colonic diverticula. Most abdominal abscesses can be successfully treated with percutaneous drainage techniques. The techniques, results, and limitations of percutaneous abscess drainage are reviewed

Abdominal organ segmentation with clinically acquired computed tomography (CT) is drawing increasing interest in the medical imaging community. Gaussian mixture models (GMM) have been extensively used through medical segmentation, most notably in the brain for cerebrospinal fluid / gray matter / white matter differentiation. Because abdominal CT exhibit strong localized intensity characteristics, GMM have recently been incorporated in multi-stage abdominal segmentation algorithms. In the context of variable abdominal anatomy and rich algorithms, it is difficult to assess the marginal contribution of GMM. Herein, we characterize the efficacy of an a posteriori framework that integrates GMM of organ-wise intensity likelihood with spatial priors from multiple target-specific registered labels. In our study, we first manually labeled 100 CT images. Then, we assigned 40 images to use as training data for constructing target-specific spatial priors and intensity likelihoods. The remaining 60 images were evaluated as test targets for segmenting 12 abdominal organs. The overlap between the true and the automatic segmentations was measured by Dice similarity coefficient (DSC). A median improvement of 145% was achieved by integrating the GMM intensity likelihood against the specific spatial prior. The proposed framework opens the opportunities for abdominal organ segmentation by efficiently using both the spatial and appearance information from the atlases, and creates a benchmark for large-scale automatic abdominal segmentation.

Directory of Open Access Journals (Sweden)

Roberts Michael S

2011-02-01

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.

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.

Fast-track (FT) postoperative protocol in oncological patients after major abdominal surgery reduces complications and length of postoperative stay compared to the conventional (CON) protocol. However, stress and pain responses have not been compared between the two protocols. To compare stress, pain, and related neuropeptidic responses (adrenocorticotropic hormone [ACTH], cortisol, and neuropeptide Y [NPY]) between FT and CON protocols. A clinical trial with repeated measurements was conducted (May 2012 to May 2014) with a sample of 63 hepatectomized or pancreatectomized patients randomized into two groups: FT ( n = 29) or CON ( n = 34). Demographic and clinical data were collected, and pain (Visual Analog Scale [VAS] and Behavioral Pain Scale [BPS]) and stress responses (3 self-report questions) assessed. NPY, ACTH, and cortisol plasma levels were measured at T1 = day of admission, T2 = day of surgery, and T3 = prior to discharge. ACTH T1 and ACTH T2 levels were positively correlated with self-reported stress levels (ρ = .43 and ρ = .45, respectively, p .05). Neuropeptidic levels were higher in the FT group. Future research should evaluate this association further, as these biomarkers might serve as objective indicators of postoperative pain and stress.

Intra-abdominal testes can be treated with several surgical procedures. We evaluated factors influencing the outcome of orchiopexy for intra-abdominal testis. We retrospectively reviewed 156 consecutive orchiopexies performed for intra-abdominal testis, defined as a nonpalpable testis on examination and located in the abdomen at surgery. All surgical approaches were included in the study. Primary outcome was the overall success rate and secondary outcomes were success based on surgical approach, age and a patent processus vaginalis. Success was considered a testis with normal texture and size compared to the contralateral testis at followup. Multivariate analysis was performed to determine factors predictive of success. The overall success rate of all orchiopexies was 79.5%. Median patient age at orchiopexy was 12 months and mean followup was 16 months. Of the patients 117 had a patent processus vaginalis at surgery. One-stage abdominal orchiopexy was performed in 92 testes with 89.1% success. Of these cases 32 were performed laparoscopically with 96.9% success. One-stage Fowler-Stephens orchiopexy was performed in 27 testes and 2-stage Fowler-Stephens orchiopexy was performed in 37 with success in 63.0% and 67.6%, respectively. Multivariate analysis revealed that 1-stage orchiopexy without vessel division had more successful outcomes than 1 and 2-stage Fowler-Stephens orchiopexy (OR 0.24, p = 0.007 and 0.29, p = 0.19, respectively). Neither age at surgery nor an open internal ring was significant (p = 0.49 and 0.12, respectively). The overall success of orchiopexy for intra-abdominal testis is 79.5%. While patient selection remains a critical factor, 1-stage orchiopexy without vessel division was significantly more successful and a laparoscopic approach was associated with the fewest failures for intra-abdominal testes.

Full Text Available Background. The increase in intra-abdominal pressure (IAP during closed abdominal hyperthermic intraperitoneal chemotherapy (HIPEC leads to major haemodynamic changes and potential organ dysfunction. We investigated these effects on hepatic blood flow (HBF and liver function in patients undergoing HIPEC following cytoreductive surgery and fluid management guided by dynamic preload indices. Methods. In this prospective observational clinical study including 15 consecutive patients, we evaluated HBF by transesophageal echocardiography and liver function by determination of the indocyanine green plasma disappearance rate (ICG-PDR. Friedman’s two-way analysis of variance by ranks and Wilcoxon signed-rank test were performed for statistical analysis. Results. During HIPEC, HBF was markedly reduced, resulting in the loss of any pulsatile Doppler flow signal in all but one patient. The ICG-PDR, expressed as median (interquartile 25–75, decreased from 23 (20–30 %/min to 18 (12.5–19 %/min (p<0.001. Despite a generous crystalloid infusion rate (27 (22–35 ml/kg/h, cardiac index decreased during the increased IAP period, inferior vena cava diameter decreased, stroke volume variation and pulse pressure variation increased, lung compliance dropped, and there was an augmentation in plateau pressure. All changes were significant (p<0.001 and reversed to baseline values post HIPEC. Conclusion. Despite optimizing intravenous fluids during closed abdominal HIPEC, we observed a marked decrease in HBF and liver function. Both effects were transient and limited to the period of HIPEC but could influence the choice between closed or open abdominal cavity procedure for HIPEC and should be considered in similar clinical situations of increased IAP.

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.

The aim of this study is to investigate the feasibility and effectiveness of laparoscopic surgery (LS) in management of abdominal lymphatic cyst (ALC) in children. Medical records of all patients undergoing LS for ALC at the National Hospital of Pediatrics, Hanoi, Vietnam, from May 2007 to June 2011 were reviewed. For LS, one umbilical port of 10 mm and up to three other 3-5-mm ports were used. Cystic fluid was aspirated prior to removal of the cyst. When intestinal resection was indicated, the mesenteric cyst with the bowel loop was delivered out of the abdomen through a minimally enlarged umbilical incision; resection of the intestinal segment together with the cyst and the bowel anastomosis were both performed extracorporally. Forty-seven patients were identified, with a mean age of 4.3 ± 3.7 years. The most common symptoms were abdominal pain (72.3%) and abdominal distention (34.0%). Four patients presented with acute abdomen due to infection or hemorrhage of the cyst. Mean size of the ALC was 9.5 ± 5.5 cm (range, 3.4-30 cm). In 12 cases the ALC was omental, and in 35 cases it was mesenteric. Laparoscopic cyst excision was performed in 36 cases (76.6%) versus laparoscopy-assisted bowel resection en bloc with the cyst in 8 cases (17.0%); in 3 patients (6.4%), conversion to open surgery was required. Mean operative time was 79 ± 39 minutes. There were no intra- or postoperative complications. Mean length of hospital stay after laparoscopic management was 3.8 ± 1.6 days. The results of pathologic investigation showed benign cystic lymphangioma in all cases. During follow-up ranging from 1 month to 4 years, recurrence was seen in 1 patient (2.1%) with complex mesenteric cyst. All other patients remained in good health. Laparoscopic management is safe, feasible, and effective and should be the treatment of choice for most cases of ALC in children.

A diagnostic approach based on clinical and radiographic examinations for evaluation of young foals and small ponies with acute abdominal discomfort is presented. Standing right to left lateral abdominal radiographs were taken of 54 foals and 6 ponies using a previously described technique. Interpretation of the radiographs was in conjuction with all clinical and laboratory findings and patient management. Using this approach, the site and cause of acute abdominal discomfort could be diagnosed accurately in 55 of 60 (91%) patients as confirmed by clinical, surgical or PM findings. Typical radiographs and photographs taken at surgery or at PM examination are presented. Typical radiographic findings, their interpretation and possible underlying gastrointestinal diseases are listed. It is concluded that the incorporation of standing lateral abdominal radiography in the clinical evaluation of foals and ponies with acute abdominal diseases gives findings of high diagnostic significance and should contribute to clinical decision-making, and that abdominal radiography can replace data from rectal palpation in foals and ponies

2015-01-01

Full text: Heterotopic bone formation within the abdominal cavity is a rare complication of the posttraumatic abdominal surgery. There are only few cases reported in the medical literature and most of them involve the mesentery or the abdominal wall. A case of 49y-old men is presented who developed intraabdominal heterotopic ossifications as a consequence of numeral exploratory laparotomies performed after a blunt abdominal trauma. The condition was detected during the follow-up MDCT 11 months later. The case is of interest because of the rarity of the condition and the diffuse character of the calcifications in the abdominal structures, which could pose some differential diagnostic difficulties

To compare the electrocautery incision with scalpel incision in patients undergoing abdominal surgery using a midline incision with respect to incision time, blood loss during incision, postoperative incision site pain and wound infection. Patients undergoing midline abdominal surgery were randomized into electrocautery and scalpel groups. The incision dimensions, incision time and blood loss during incision were noted intraoperatively. Postoperative pain and wound infection were recorded on every postoperative day for one week. 41 patients in each of the two groups were analyzed. Gender and age distribution was similar in both the groups. The mean incision time per unit wound area in the electrocautery group and scalpel group was 9.40 ± 3.37 s/cm(2) and 9.07 ± 3.40 s/cm(2) (p = 0.87) respectively. The mean blood loss per unit wound area was significantly lower in the electrocautery group at 6.46 ± 3.94 ml when compared to that of 23.40 ± 15.28 ml in the scalpel group (p= electrocautery and scalpel groups (14.63% vs. 12.19%; p = 0.347). With a comparable Postoperative incision site pain, wound infection rate and significantly lower blood loss with the equal time taken for the incision, electrocautery can be considered safe and effective in making skin incision in midline laparotomy compared to scalpel incision.

Chronic Abdominal Wall Pain.

Koop, Herbert; Koprdova, Simona; Schürmann, Christine

2016-01-29

Chronic abdominal wall pain is a poorly recognized clinical problem despite being an important element in the differential diagnosis of abdominal pain. This review is based on pertinent articles that were retrieved by a selective search in PubMed and EMBASE employing the terms "abdominal wall pain" and "cutaneous nerve entrapment syndrome," as well as on the authors' clinical experience. In 2% to 3% of patients with chronic abdominal pain, the pain arises from the abdominal wall; in patients with previously diagnosed chronic abdominal pain who have no demonstrable pathological abnormality, this likelihood can rise as high as 30% . There have only been a small number of clinical trials of treatment for this condition. The diagnosis is made on clinical grounds, with the aid of Carnett's test. The characteristic clinical feature is strictly localized pain in the anterior abdominal wall, which is often mischaracterized as a "functional" complaint. In one study, injection of local anesthesia combined with steroids into the painful area was found to relieve pain for 4 weeks in 95% of patients. The injection of lidocaine alone brought about improvement in 83-91% of patients. Long-term pain relief ensued after a single lidocaine injection in 20-30% of patients, after repeated injections in 40-50% , and after combined lidocaine and steroid injections in up to 80% . Pain that persists despite these treatments can be treated with surgery (neurectomy). Chronic abdominal wall pain is easily diagnosed on physical examination and can often be rapidly treated. Any physician treating patients with abdominal pain should be aware of this condition. Further comparative treatment trials will be needed before a validated treatment algorithm can be established.

In 2009, the NHS evidence adoption center and National Institute for Health and Care Excellence (NICE) published a review of the use of endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms (AAAs). They recommended the development of a risk-assessment tool to help identify AAA patients with greater or lesser risk of operative mortality and to contribute to mortality prediction.A low anaerobic threshold (AT), which is a reliable, objective measure of pre-operative cardiorespiratory fitness, as determined by pre-operative cardiopulmonary exercise testing (CPET) is associated with poor surgical outcomes for major abdominal surgery. We aimed to assess the impact of a CPET-based risk-stratification strategy upon perioperative mortality, length of stay and non-operative costs for elective (open and endovascular) infra-renal AAA patients. A retrospective cohort study was undertaken. Pre-operative CPET-based selection for elective surgical intervention was introduced in 2007. An anonymized cohort of 230 consecutive infra-renal AAA patients (2007 to 2011) was studied. A historical control group of 128 consecutive infra-renal AAA patients (2003 to 2007) was identified for comparison.Comparative analysis of demographic and outcome data for CPET-pass (AT ≥ 11 ml/kg/min), CPET-fail (AT 11 ml/kg/min was associated with reduced perioperative mortality (open cases only), LOS, survival and inpatient costs (open and endovascular repair) for elective infra-renal AAA surgery.

Abdominal aortic aneurysms and abdominal hernias become an important health problems of our times. Abdominal aortic aneurysm and its rupture is one of the most dangerous fact in vascular surgery. There are some theories pointing to a multifactoral genesis of these kinds of diseases, all of them assume the attenuation of abdominal fascia and abdominal aortic wall. The density and continuity of these structures depend on collagen and elastic fibers structure. Reducing the strength of the fibers may be due to changes in the extracellular matrix (ECM) by the proteolytic enzymes-matrix metalloproteinases (MMPs) that degrade extracellular matrix proteins. These enzymes play an important role in the development of many disease: malignant tumors (colon, breast, lung, pancreas), cardiovascular disease (myocardial infarction, ischemia-reperfusion injury), connective tissue diseases (Ehler-Danlos Syndrome, Marfan's Syndrome), complications of diabetes (retinopathy, nephropathy). One of the most important is matrix metalloproteinase-2 (MMP-2). The aim of the study was an estimation of the MMP-2 blood levels in patients with abdominal aortic aneurysm and primary abdominal hernia, and in patients with only abdominal aortic aneurysm. The study involved 88 patients aged 42 to 89 years, including 75 men and 13 women. Patients were divided into two groups: patients with abdominal aortic aneurysm and primary abdominal hernia (45 persons, representing 51.1% of all group) and patients with only abdominal aortic aneurysm (43 persons, representing 48,9% of all group). It was a statistically significant increase in MMP-2 blood levels in patients with abdominal aortic aneurysm and primary abdominal hernia compared to patients with only abdominal aortic aneurysm. It was a statistically significant increase in the prevalence of POCHP in patients with only abdominal aortic aneurysm compared to patients with abdominal aortic aneurysm and primary abdominal hernia. Statistically significant

To determine the cosmetic appeal of different incision types used in gynecologic surgery. One hundred women between the ages of 20 and 40 years were shown 4 color photographs of a female abdomen with incision sites marked for Pfannenstiel, minilaparotomy, traditional laparoscopy, and robotic-assisted laparoscopy. The women were asked to rank the photographs on cosmetic appeal alone. An additional photograph depicting single-port laparoscopy was then added, and patients were asked to again rank the photographs. Participants were also asked basic demographic information and prior surgical history. Office practice. One hundred women between the ages of 20 and 40. Participants. Minilaparotomy was ranked as the most appealing incision among the first set of photographs by 74% of the participants, and the remaining 26% preferred traditional laparoscopy. Robotic-assisted laparoscopy was ranked as the least appealing scar type by 42%, and no patient selected it as their first choice. Sixty-four percent preferred the appearance of a single-port laparoscopic scar when that option was added. The only demographic variable that reached statistical significance was the presence of prior abdominal surgery. Patients without prior surgery ranked minilaparotomy as more cosmetically appealing. When several minimally invasive surgical approaches are possible, the patient should be counseled regarding the cosmetic results of each. Patients in this study strongly preferred the appearance of minilaparotomy and single-port incisions over full Pfannenstiel or robotic incisions. Copyright © 2014 AAGL. Published by Elsevier Inc.

Contrast-enhanced computed tomography colonography (CE-CTC) is a useful guide for the laparoscopic surgeon to avoid incorrectly removing the colonic segment and the failure to diagnose of synchronous colonic and extra-colonic lesions. Lymph node dissection and vessel ligation under a laparoscopic approach can be time-consuming and can damage vessels and organs. Moreover, mesenteric vessels have extreme variations in terms of their courses and numbers. We describe the benefit of using an abdominal vascular map created by CE-CTC in laparoscopic colorectal surgery candidates. We describe patients with different diseases (colorectal cancer, diverticular disease, and inflammatory bowel disease) who underwent CE-CTC just prior to laparoscopic surgery

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.

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.

2013-02-01

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.

Six patients with abdominal aortic aneurysm (AAA) were studied with three-dimensionally reconstructed CT angiography (3D-CTA) in order to evaluate its usefulness as a diagnostic tool for vascular surgery patients. Images of the intravenously contrasted abdominal aorta were obtained with spiral scan during a single breath hold. The images of the abdominal aorta and its major branches were three-dimensionally reconstructed with a shaded surface display mode. The three-dimensional image reconstruction was successful in all the six cases and performed without difficulties. Shaded surface display presented a deficit to depict the aortic wall with mural thrombus. However, multidirectional display of the abdominal aorta and its branches facilitated interpretation of the anatomical details of the lesions and planning of surgical repair. 3D-CTA is an alternative to conventional aortography for preoperative diagnosis of AAA. Moreover it was shown to be noninvasive, easy to proceed. It presented good angiographical resolution that can be used as a precise diagnostic tool in vascular surgery. (author)

Delayed gastrointestinal recovery after abdominal operation – role of alvimopan

Directory of Open Access Journals (Sweden)

Berger NG

2015-08-01

Full Text Available Nicholas G Berger, Timothy J Ridolfi, Kirk A LudwigDivision of Colorectal Surgery, Department of Surgery, Medical College of Wisconsin, Milwaukee, Wisconsin USAAbstract: Postoperative Ileus (POI, which occurs after surgical manipulation of the bowel during abdominal operations, is associated with prolonged hospital stay, increasing medical costs, and delayed advancement of enteral diet, which contributes to a significant economic burden on the healthcare system. The use of accelerated care pathways has shown to positively impact gut function, but inevitable postoperative opioid use contributes to POI. Alvimopan is a peripherally acting µ-opioid receptor antagonist designed to mitigate antimotility effects of opioids. In our review, we examined ten trials on alvimopan's use after abdominal operations. Several of the earlier studies on patients undergoing bowel resection showed correlations between the study group and GI recovery as defined by passage of flatus, first bowel movement, and time to readiness for discharge. Data in patients undergoing total abdominal hysterectomy showed similarly decreased GI recovery time. Additionally, data within the past few years shows alvimopan is associated with more rapid GI recovery time in patients undergoing radical cystectomy. Based on our review, use of alvimopan remains a safe and potentially cost-effective means of reducing POI in patients following open GI surgery, radical cystectomy, and total abdominal hysterectomy, and should be employed following these abdominal operations.Keywords: postoperative ileus, alvimopan, ileus, bowel resection, return of bowel function

The authors report the personal techniques and the results of CT-guided percutaneous drainage of postoperative abdominal fluid collections. CT-guided percutaneous drainage offers many advantages over surgery: it is less invasive, can be repeated and requires no anesthesia, there are not surgery-related risks and lower morbidity and mortality rates. Moreover, subsequent hospitalization is shorter and costs are consequently reduced. The authors conclude that CT-guided percutaneous drainage is the method of choice in the treatment of postoperative abdominal fluid collections [it

Increased pressure within the abdominal compartment: intra-abdominal hypertension and the abdominal compartment syndrome.

Roberts, Derek J; Ball, Chad G; Kirkpatrick, Andrew W

2016-04-01

This article reviews recent developments related to intra-abdominal hypertension (IAH)/abdominal compartment syndrome (ACS) and clinical practice guidelines published in 2013. IAH/ACS often develops because of the acute intestinal distress syndrome. Although the incidence of postinjury ACS is decreasing, IAH remains common and associated with significant morbidity and mortality among critically ill/injured patients. Many risk factors for IAH include those findings suggested to be indications for use of damage control surgery in trauma patients. Medical management strategies for IAH/ACS include sedation/analgesia, neuromuscular blocking and prokinetic agents, enteral decompression tubes, interventions that decrease fluid balance, and percutaneous catheter drainage. IAH/ACS may be prevented in patients undergoing laparotomy by leaving the abdomen open where appropriate. If ACS cannot be prevented with medical or surgical management strategies or treated with percutaneous catheter drainage, guidelines recommend urgent decompressive laparotomy. Use of negative pressure peritoneal therapy for temporary closure of the open abdomen may improve the systemic inflammatory response and patient-important outcomes. In the last 15 years, investigators have better clarified the pathogenesis, epidemiology, diagnosis, and appropriate prevention of IAH/ACS. Subsequent study should be aimed at understanding which treatments effectively lower intra-abdominal pressure and whether these treatments ultimately affect patient-important outcomes.

Evidence-Based Assignment of Diagnostic Peritoneal Lavage (DPL Sensitivity in Penetrating Abdominal Trauma

2008-02-01

Full Text Available Background:There are a large number of patients with penetrating abdominal trauma who have normal vital signs and negative abdominal examination when referred to trauma centers. Agreat deal of controversy exists between authorities about screening these patients for emergency explorative laparotomy. Many references have reported more than 90% sensitivity for DPL as a diagnostic method to determine whether intraabdominal injuries were present and emergent laparotomy is indicated or not. This study is for reassignment of this sensitivity according to our own evidence. Methods: All of the patients with abdominal stab wounds and normal vital signs plus negative abdominal examination who were referred to Shohada-e-Tajrish hospital between March 2004 to December 2005, underwent local wound exploration and those confirmed to have peritoneal penetration, underwent emergency laparotomy. In the operating room and prior to surgery, under general anesthesia, DPL was performed. Then DPL results were compared with laparotomy findings and DPL sensitivity was assigned. Results: Of the total number of 34 patients, 8 had a positive DPL and positive laparotomy; 2 had a positive DPL and negative laparotomy; 8 had negative DPL and positive laparotomy, and 16 patients had negative DPL and negative laparotomy. Conclusion: According to our study, DPL sensitivity is much less than mentioned in trauma texts (approximately 50%. So, it is not a valuable tool to discriminate between operative and conservative approaches in penetrating abdominal trauma. We suggest more sensitive modalities. Laparotomy is the most sensitive approach but at the price of a high negative laparotomy rate.

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.

Objective: to propose a model to standardize computed tomography reports on abdominal aortic aneurysms. Materials and methods: interviews were carried out with members of the Vascular Surgery Division of our institution, in the period between April and October 2004, aiming at developing a standardized model of computed tomography reports on abdominal aortic aneurysms. Based on this model, a questionnaire was elaborated and sent to other nine surgeons, all of them experienced in the field of abdominal aortic surgery. The questionnaires response rate was 55.5% (5/9). Results: the most frequently mentioned parameters of interest for evaluation of abdominal aortic aneurysms were: maximum diameter of proximal aortic neck, proximal aortic neck length to lower renal arteries, shape of proximal aortic neck, maximum diameter of the aneurysm and diameter of the common iliac arteries. These data allowed the development of a proposal for a model to standardize computed tomography reports. Conclusion: a model for standardized tomographic analysis of abdominal aortic aneurysms has met vascular surgeons' needs for following-up patients and planning their treatment. (author)

This study evaluated the safety, feasibility, and clinical utility of transhepatic drainage of inaccessible abdominal abscesses retrospectively under real-time computed tomographic (CT) guidance. For abdominal abscesses, 12 consecutive patients received percutaneous transhepatic drainage. Abscesses were considered inaccessible using the usual access route because they were surrounded by the liver and other organs. The maximum diameters of abscesses were 4.6-9.5 cm (mean, 6.7 ± 1.4 cm). An 8-Fr catheter was advanced into the abscess cavity through the liver parenchyma using real-time CT fluoroscopic guidance. Safety, feasibility, procedure time, and clinical utility were evaluated. Drainage catheters were placed with no complications in abscess cavities through the liver parenchyma in all patients. The mean procedure time was 18.8 ± 9.2 min (range, 12-41 min). All abscesses were drained. They shrank immediately after catheter placement. In conclusions, this transhepatic approach under real-time CT fluoroscopic guidance is a safe, feasible, and useful technique for use of drainage of inaccessible abdominal abscesses.

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

A background in minimally invasive colorectal surgery (MICS) has been thought to be essential prior to robotic-assisted colorectal surgery (RACS). Our aim was to determine whether MICS is essential prior to starting RACS training based on results from our initial experience with RACS. Two surgeons from our centre received robotic training through the European Academy of Robotic Colorectal Surgery (EARCS). One surgeon had no prior formal MICS training. We reviewed the first 30 consecutive robotic colorectal procedures from a prospectively maintained database between November 2014 and January 2016 at our institution. Fourteen patients were male. Median age was 64.5 years (range 36-82) and BMI was 27.5 (range 20-32.5). Twelve procedures (40%) were performed by the non-MICS-trained surgeon: ten high anterior resections (one conversion), one low anterior resection and one abdomino-perineal resection of rectum (APER). The MICS-trained surgeon performed nine high and four low anterior resections, one APER and in addition three right hemicolectomies and one abdominal suture rectopexy. There were no intra-operative complications and two patients required re-operation. Median post-operative stay was five days (range 1-26). There were two 30-day re-admissions. All oncological resections had clear margins and median node harvest was 18 (range 9-39). Our case series demonstrates that a background in MICS is not essential prior to starting RACS training. Not having prior MICS training should not discourage surgeons from considering applying for a robotic training programme. Safe and successful robotic colorectal services can be established after completing a formal structured robotic training programme.

The Impact of Two Different Transfusion Strategies on Patient Immune Response during Major Abdominal Surgery: A Preliminary Report

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 In the recent times there has been increased incidence of abdominal trauma cases due to several causes. Quick and prompt intervention is needed to decrease the mortality of the patients. So we conducted a study to assess the cause and the management of abdominal trauma cases in our institution. The aim of this study was to know the incidence of blunt and penetrating injuries and their causes, age and sex incidence, importance of various investigations, mode of treatment offered and post-operative complications. To study the cause of death and evolve better management. MATERIALS AND METHODS The present study comprises of patients admitted to and operated in various surgical units in the Department of Surgery at Government General Hospital, attached to Guntur Medical College Guntur, from August 2014 to October 2016. RESULTS Increase incidence seen in age group 20-29 years (30%. Male predominance 77.5%. Mechanism of injury–road traffic accidents 65%. Isolated organ injury–colon and rectum 40%. Other associated injuries–chest injuries with rib fractures 7.5%. Complications–wound infection 17.5%. Duration of hospital stay 8–14 days. Bowel injury management–closure of perforation 84.6%. Resection anastomosis 15.38%. CONCLUSION Thorough clinical examination, diagnostic paracentesis, plain X-ray erect abdomen and ultrasound proved to be very helpful in the diagnosis of intra-abdominal injuries. Spleen is the commonest organ involved in blunt trauma and colon is the commonly injured organ in penetrating abdominal trauma, many patients have associated extremity and axial skeleton injuries. With advances in diagnosis and intensive care technologies, most patients of solid visceral injuries with hemodynamic stability can be managed conservatively. Surgical site infection is the most common complication following surgery. The mortality is high; reason might be patient reaching the hospital late, high incidence of postoperative septic

The management of splenic injuries has shifted from splenectomy to splenic preservation owing to the risk of overwhelming post-splenectomy infection (OPSI). This study aimed to identify the factors that determine splenectomy in patients with isolated splenic injuries, with a view to increasing the rate of splenic preservation. Files of 55 patients managed for isolated splenic injuries from blunt abdominal trauma between 1998 and 2007 were retrospectively analysed using a pro forma. Management options were classified into nonoperative, operative salvage and splenectomy. The majority of patients suffered splenic injury as a result of motor vehicle accident (MVA) trauma or falls. Splenectomy was undertaken in 33 (60%) patients, 12 (22%) had non-operative management, and operative salvage was achieved in 10 (18%) patients. Significant determinants of splenectomy were grade of splenic injury, hierarchy of the surgeon, and hierarchy of the assistant. MVA injury and falls accounted for the vast majority of blunt abdominal trauma in this study. The rate and magnitude of energy transferred versus splenic protective mechanisms at the time of blunt abdominal trauma seems to determine the grade of splenic injury. Interest in splenic salvage surgery, availability of technology that enables splenic salvage surgery, and the experience of the surgeon and assistant appear to determine the surgical management. Legislation on vehicle safety and good parental control may reduce the severity of splenic injury in blunt abdominal trauma. When surgery is indicated, salvage surgery should be considered in intermediate isolated splenic injury to reduce the incidence of OPSI.

Abdominal pregnancy, a rare diagnosis, belongs to the ectopic pregnancy group, the leading cause of pregnancy related exitus. The positive diagnosis is very difficult to establish most often in an acute setting, leading to a staggering percent of feto-maternal morbidity and mortality. We present the case of 26-weeks-old abdominal pregnancy with partial feto-placental detachment in a patient, after hysteroscopy and in vitro fertilization, which until the acute symptoms that led to emergency laparotomy went unrecognized. The patient recovered completely and satisfactorily after surgery and, due to the high risk of uterine rupture with regard to a second pregnancy, opted for a surrogate mother. Abdominal pregnancy can be regarded as a difficult to establish diagnosis, with a greater chance in case of increased awareness. It is compulsory to be well informed in order not to be surprised by the diagnosis and to apply the correct treatment immediately as the morbidity and mortality rate is elevated.

Intra-abdominal hemorrhage after open heart surgery is very uncommon in routine clinical practice. There are case reports of having bleeding from spleen or liver after starting low molecular weight heparin (LMWH) postoperatively. Our patient is a 58-year-old man with mitral valve regurgitation, who underwent mitral valve repair and developed intra-abdominal hemorrhage 8h after open heart surgery. The exploratory laparotomy revealed the source of bleeding from ruptured sub-capsular liver hematoma and oozing from raw areas of the liver surface. Liver packing was done to control the bleeding. The gastrointestinal complications after open heart surgery are rare and spontaneous bleeding from spleen has been reported. This is the first case from our hospital to have intra-abdominal hemorrhage after open heart surgery. Spontaneous bleeding from liver is a possible complication after open heart surgery. We submit the case for the academic interest and to discuss the possible cause of hemorrhage. Copyright © 2013 The Authors. Published by Elsevier Ltd.. All rights reserved.

INTRODUCTION The aim of this study was to assess the value of the Hardman Index and the Glasgow Aneurysm Score in predicting postoperative mortality in patients with ruptured abdominal aortic aneurysm (rAAA), and to assess the correlation between the two. PATIENTS AND METHODS Patients admitted with rAAA were identified from a hospital database. Hospital records were reviewed and a retrospective Hardman Index and Glasgow Aneurysm Score was calculated. Poor postoperative prognosis was considered at a Glasgow Aneurysm Score > 95 or a Hardman Index ≥ 3. RESULTS A total of 96 patients with a median age of 77.5 years (interquartile range, 71–83 years) and a male:female ratio of 2:1 were identified. Of these, 37 patients were not offered surgery and this was associated with 100% mortality. Of the 59 operated patients, 36 (61%) patients died postoperatively. Operated patients had a median Glasgow Aneurysm Score of 91 (interquartile range, 77–101) and a Hardman Index of 2 (interquartile range, 1–2). In this group, a Glasgow Aneurysm Score > 95 or a Hardman Index ≥ 3 was not associated with mortality (P = 0.10 and P = 0.79, respectively). Correlation between the scoring systems was poor (+0.42 τb). CONCLUSIONS The scoring systems assessed did not help predict the outcome of rAAA surgery, and correlated poorly with each other. They do not aid clinical judgement. PMID:19102824

Abdominal hernias are a common clinical problem Clinical diagnosis of abdominal hernias can sometimes be challenging, particularly in obese patients or patients with previous abdominal surgery. CT scan of the abdomen allows visualization of hernias and their contents and the differentiation from other masses of the abdominal wall such as tumors, hematomas and abscesses. Moreover, CT may identify complications such as incarceration, bowel obstruction, volvulus and strangulation. This study illustrates the CT scan findings observed in different types of abdominal wall hernias. (author)

Full Text Available Introduction: Respiratory and blood pressure changes as well as fluid administration alter the acid-base balance during the perioperative period which may cause consciousness disturbance and additional hemodynamic disorders. The aim of this study was to identify frequent postoperative acid-base disturbances in order to control postoperative complications. Materials and Methods:This prospective, observational study design was used on patients who underwent abdominal surgery during a six-month period. Gasometry was performed immediately after the patients’ admittion to ICU and six and 12 hours postoperatively. SPSS v13 software was used, and PResults: 213 patients (123 male and 90 female aged 14-85 years (51.7± 22.4 were evaluated. During admission, PH and PaCO2 were (7.29±0.13 and (38.3±11.9, respectively; however, although PH increased gradually (P=0.001, PaCO2 was reduced (P=0.03. Bicarbonate and base excess had opposite effects; bicarbonate initially decreased but increased after 12 hours (P=0.001, whereas base excess initially increased (-6.3±11.6 and then decreased gradually (P=0.003. The arterial oxygen pressure was reduced for 22.5% of the patients throughout the admission period, and this did not significantly change (P=0.57. Conclusion: According to the results, in admission, 65.7% had metabolic acidosis, but metabolic alkalosis was the least. Gradually, metabolic acidosis was modified, but metabolic alkalosis increased. Intraoperative hypotension and fluid infusion may be the main factors of early metabolic acidosis and control of hypotension, or correction of acidosis may increase metabolic alkalosis.

Full Text Available Background: Infectious complications of hysterectomy remain common despite the use of antibiotic. The usual existing methods of preoperative antisepsis do not control the vaginal bacteria that are the primary cause of contamination at the surgical site. Our goal was to assess whether febrile morbidity after total abdominal hysterectomy is decreased by the addition of povidone-iodine gel at the vaginal apex after the routine vaginal preparation with povidone-iodine solution.Methods: We carried out a prospective randomized trial on women admitted for elective abdominal hysterectomy. Inclusion criteria included planned abdominal hysterectomy for benign or malignant gynecologic conditions. Exclusion criteria consisted of emergency surgery, current treatment for pelvic infection, and known povidone-iodine allergy. A total of 168 patients were randomized to either the control group or the intervention group, who received 20 cc povidone-iodine gel placed at the vaginal apex immediately before the operation. Both groups received the routine preoperative preparation of antimicrobial prophylaxis, abdominal and vaginal scrubbing with povidone-iodine solution prior to the operation. The primary outcome was post-operative febrile morbidity. Other outcomes included abdominal wound infection, vaginal cuff cellulitis or pelvic abscess. Data was analyzed using Fisher's exact test. p<0.05 was considered statistically significant.Results: The overall rate of febrile morbidity was 20.5%. Febrile morbidity occurred in ten of 80 (12.5% women receiving the povidone-iodine gel preparation and 24 of 86 (27.9% women not receiving the gel (p<0.05. The rate of abdominal wound infection was 18.6% (16 in the control group, and 5% (4 in the gel group (p<0.05. Vaginal cuff cellulitis was seen in three patients from the control group versus one woman from the gel group (p>0.05.

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 Adnexal torsion is an infrequent but significant cause of acute lower abdominal pain in women. While adnexal torsion is generally considered in premenopausal women presenting with acute abdominal pain and a pelvic mass, it is a rare cause of acute abdominal pain during postmenopausal period. The diagnosis of adnexal torsion is often challenging due to nonspesific clinical, laboratory and physical examination findings. Causes of adnexal torsion is also different in premenopausal and postmenopausal women. While a simple functional cyst is often the cause of torsion in premenopausal women, it is more rarely the cause in postmenopausal women. Adnexal torsion is a surgical emergency. The surgery of adnexal torsion is performed either via conventional exploratory laparotomy or laparoscopic surgery. Adnexal torsion in postmenopausal women should be considered not only in the setting of sudden onset pain, but also in long-term abdominal discomfort. In this article, we presented a case with adnexal torsion that rarely cause acute abdominal pain in postmenopausal women. [Cukurova Med J 2016; 41(1.000: 167-170

Daniella Matos da Silva

Full Text Available ABSTRACT: Intraoperative ultrasonography (IOUS is used in medicine for diagnosis and guidance during oncologic surgery. The aims of this study were to assess the performance, feasibility, advantages and difficulties of the IOUS technique in dogs with suspected intra-abdominal tumors. The study included nine client-owed dogs that had suspected intra-abdominal tumors (spleen, liver or bowel based on transabdominal ultrasound examination and that were subsequently referred for exploratory laparotomy surgery. During surgery, IOUS was performed; results of preoperative transabdominal ultrasonography, inspection by the surgeon and IOUS were compared on a case-by-case basis. IOUS was helpful in determining lesion resection in all cases. Lesions detected solely by the use of IOUS were observed in seven out of nine cases. Analysis of these cases demonstrated that IOUS can be a tool to assist during oncology surgery on the liver, spleen or bowel. Dogs with hepatic tumors can have small non-palpable intraparenchymal nodules, which may be visible by IOUS.

Intra-abdominal cryptococcosis was diagnosed in two young dogs. The first, an entire male border collie, was presented with vomiting. An abdominal mass detected during physical examination proved to be cryptococcal mesenteric lymphadenitis on exploratory laparotomy. The second dog, a female neutered giant schnauzer, was presented with neurological signs suggestive of encephalopathy. Intestinal cryptococcal granulomas were detected in an extensive diagnostic investigation which included abdominal ultrasonography. The gastrointestinal tract was considered the most likely portal of entry for cryptococcal organisms in both cases. Both dogs were treated using surgery and multiagent antifungal chemotherapy. The first case succumbed despite therapy, while the second dog was treated successfully as gauged by return to clinical normality and a substantial decline in the cryptococcal antigen titre which continued to fall after cessation of treatment.

Full Text Available Epiploic appendagitis (EA is an uncommon cause of abdominal pain. It is a benign condition but may mimic other serious causes of acute abdomen such as appendicitis, diverticulitis, and gynecological emergency in severe cases. Knowledge of this condition in the differential diagnosis of abdominal pain can save unnecessary hospital admission, antibiotics, and surgery. In this article, we present the case of a 43-year-old female who presented to our hospital with a 2-day history of right lower quadrant abdominal pain and diarrhea. She was diagnosed with EA with computed tomography of abdomen with contrast and was managed conservatively with good outcome.

An abnormal dilatation of the abdominal aorta is referred to as an abdominal aortic aneurysm (AAA). Due to the risk of rupture, surgical repair is offered electively to individuals with aneurysms greater than 5.5 cm in size. Traditionally, conventional open surgical repair (OSR) was considered the first choice approach. However, over the past two decades endovascular aneurysm repair (EVAR) has gained popularity as a treatment option. This article intends to review the role of EVAR in the management of elective AAA. To assess the effectiveness of EVAR versus conventional OSR in individuals with AAA considered fit for surgery, and EVAR versus best medical care in those considered unfit for surgery. This was determined by the effect on short, intermediate and long-term mortality, endograft related complications, re-intervention rates and major complications. The Cochrane Peripheral Vascular Diseases Group Trials Search Co-ordinator (TSC) searched the Specialised Register (January 2013) and the Cochrane Central Register of Controlled Trials (CENTRAL) (2012, Issue 12). The TSC also searched trial databases for details of ongoing or unpublished studies. Prospective randomised controlled trials (RCTs) comparing EVAR with OSR in individuals with AAA considered fit for surgery. and comparing EVAR with best medical care in individuals considered unfit for surgery. We excluded studies with inadequate data or using an inadequate randomisation technique. Three reviewers independently evaluated trials for appropriateness for inclusion and extracted data using pro forma designed by the Cochrane PVD Group. We assessed the quality of trials using The Cochrane Collaboration's 'Risk of bias' tool. We entered collected data in to Review Manager (version 5.2.3) for analysis. Where direct comparisons could be made, we determined odds ratios (OR). We tested studies for heterogeneity and, when present, we used a random-effects model; otherwise we used a fixed-effect model.

Full Text Available OBJECTIVE AND METHODS: Screening for abdominal aortic aneurysms may be useful to decrease mortality related to rupture. We conducted a study to assess the prevalence of abdominal aortic aneurysms in southern Brazil and to define risk factors associated with high prevalence of this disorder. The screening was conducted using abdominal ultrasound. Three groups were studied: Group 1 - cardiology clinic patients; Group 2 - individuals with severe ischemic disease and previous coronary surgery, or important lesions on cardiac catheterism; Group 3 - individuals without cardiac disease selected from the general population. All individuals were male and older than 54 years of age. The ultrasonographic diagnosis of aneurysm was based on an anteroposterior abdominal aorta diameter of 3 cm, or on an abdominal aorta diameter 0.5 cm greater than that of the supra-renal aorta. RESULTS: A total of 2.281 people were screened for abdominal aortic aneurysms in all groups: Group 1 - 768 individuals, Group 2 - 501 individuals, and Group 3 - 1012 individuals. The prevalence of aneurysms was 4.3%, 6.8% and 1.7%, respectively. Age and cigarette smoking were significantly associated with increased prevalence of aneurysms, as was the diagnosis of peripheral artery disease. DISCUSSION: We concluded that screening may be an important tool to prevent the mortality associated with abdominal aortic aneurysms surgery. Additionally, the cost of screening can be decreased if only individuals presenting significant risk factors, such as coronary and peripheral artery disease, smokers and relatives of aneurysm patients, are examined.OBJETIVO E MÉTODOS: O rastreamento de aneurisma da aorta abdominal infra-renal é importante pois pode diminuir a mortalidade relacionada à ruptura.

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.

Intestinal stomas (ostomies) have been associated negatively with multiple aspects of health-related quality of life. This article examines the relationship between employment status and psychological well-being (PWB) in veterans who underwent major bowel procedures with or without ostomy. Veterans from 3 Veterans Affairs (VA) medical centers were surveyed using the City of Hope ostomy-specific questionnaire and the Short Form 36 item Veteran's version (SF-36V). Response rate was 48% (511 of 1,063). Employment and PWB relationship was assessed using multiple regression with age, income, SF-36V physical component summary (PCS), and employment status as independent variables. Employed veterans reported higher PWB compared with unemployed veterans (P = .003). Full-time workers also reported higher PWB than part-time or unemployed workers (P = .001). Ostomy was not an independent predictor of PWB. Employment among veterans after major abdominal surgery may have intrinsic value for PWB. Patients should be encouraged to return to work, or do volunteer work after recovery. Published by Elsevier Inc.

Abdominal surgical site infections (SSI) cause substantial morbidity and mortality for patients undergoing operative procedures. We determined the incidence of and risk factors for SSI after abdominal surgery in the Department of Abdominal Surgery at the University Clinical Centre of Kosovo (UCCK). Prospective surveillance of patients undergoing abdominal surgery was performed between December 2005 and June 2006. CDC definitions were followed to detect SSI and study forms were based on Europe Link for Infection Control through Surveillance (HELICS) protocol. A total of 253 surgical interventions in 225 patients were evaluated. The median age of patients was 42 years and 55.1% of them were male. The overall incidence rate of SSI was 12%. Follow-up was achieved for 84.1% of the procedures. For patients with an SSI, the median duration of hospitalization was 9 days compared with 4 days for those without an SSI (p 2, use of antibiotic prophylaxis and NNIS class of > 2 were all significant at p < .001. The SSI rates for the NNIS System risk classes 0, 1 and 2-3 were 4.2%, 46.7% and 100%, respectively. SSI caused considerable morbidity among surgical patients in UCCK. Appropriate active surveillance and infection control measures should be introduced during preoperative, intra-operative, and postoperative care to reduce infection rates.

Endometriomas are a rare cause of abdominal wall pain. We report a case of a port site endometrioma presenting with an umbilical swelling. The patient underwent a laparoscopy for pelvic endometriosis 6 months previously and presented with a swelling around her umbilical port site scar associated with cyclical pain during menses. Ultrasound scan reported a well-defined lesion in the umbilicus and MRI scanning excluded other pathology. As she was symptomatic, she underwent an exploration of the scar and excision of the endometrioma with resolution of her symptoms. Precautions should be taken to reduce the risk of endometrial seeding during laparoscopic surgery. All tissues should be removed in an appropriate retrieval bag and the pneumoperitoneum should be deflated completely before removing ports to reduce the chimney effect of tissue being forced through the port site. The diagnosis should be considered in all women of reproductive age presenting with a painful port site scar. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

To describe the success rate and the complications after procedures to diagnose abdominal non-Hodgkin's lymphoma in children and adolescents. A retrospective cross-sectional study was conducted with a population consisting of children and adolescents with abdominal non-Hodgkin's lymphoma diagnosed between September 1994 and December 2012. The sample comprised of 100 patients who underwent 113 diagnostic procedures, including urgent surgery (n=21), elective surgery (n=36), and non-surgical diagnosis (n=56). The most frequent procedures were laparotomy (46.9%) and ultrasound-guided core biopsy (25.6%). The rate of diagnostic success was 95.2% for urgent surgeries; 100% for elective surgeries and 82.1% for non-surgical procedures (p<0.05). The rates of complication during the three diagnosis procedures considered were significant (p<0.001; 95.2% of the urgent surgeries, 83.8% of the elective surgeries, and 10.7% of the non-surgical procedures). The length of time before resuming a full diet and starting chemotherapy was significantly reduced for patients who underwent non-surgical procedures when compared with the other procedures (p<0.001). Non-surgical procedures for the diagnosis of pediatric abdominal non-Hodgkin's lymphoma are an effective option with low morbidity rate, allowing an earlier resumption of a full diet and chemotherapy initiation. Furthermore, non-surgical procedures should also be considered for obtaining tumor samples from patients with extensive disease. Copyright © 2017. Published by Elsevier Editora Ltda.

Traditionally, stab wounds violating the abdominal wall fascia led to exploratory celiotomy that was often nontherapeutic. In an attempt to limit the number of nontherapeutic celiotomies (NTC), we devised a protocol to prospectively study stab wounds violating the anterior abdominal wall fascia. Through protocol, abdominal stab wounds were explored in stable adults. If the anterior fascia was violated, paracentesis and, if necessary, peritoneal lavage was undertaken in the absence of previous abdominal surgery. If evisceration was noted, it was reduced and the patient lavaged. Fascial penetration was noted in 72 patients. 46 patients underwent celiotomy: because of shock/peritonitis in 8 (2 NTC), fascial penetration with a history of previous celiotomy in 7 (5 NTC), positive paracentesis in 20 (5 NTC), or positive lavage in 10 (4 NTC). One patient underwent late celiotomy without ill-effect after a negative lavage because she subsequently developed fever and localized peritonitis (ice pick injury to cecum). Eleven patients had evisceration; nine underwent celiotomy. Patients with abdominal stab wounds can be selectively managed safely. More than one-third with fascial penetration, some with evisceration, avoided exploration. Only one patient underwent delayed celiotomy and did so without detriment. Nontherapeutic celiotomy rates were highest in patients with previous abdominal surgery who, thereby, could not undergo paracentesis/lavage; excluding these patients, the nontherapeutic celiotomy rate was 17% (11/65) for those with fascial penetration.

In this case we presented a patient who were admitted to surgery department with complaints of abdominal pain and nausea. There were no pathological findings on physical examination, direct abdominal x-ray, chest radiograph and biochemical parameters. At proximal of the celiac trunk, it was shown approximately 3x2 cm in size fusiform aneurysmal dilatation on the patient%u2019s abdominal ultrasonography and turbulence, arterial flow on the patient%u2019s abdominal doppler ultrasonography subsequently. In abdominal computed tomography we detected dense calcifications, dilatation and hypodensities that may belong to a thrombus in the lumen superior mesenteric vein (SMV. At the same time, approximately 3.5 cm segment of trunk celiak we observed aneurysm dilatation which reaching 2 cm at the widest point. Celiac trunk aneurysm is a rare cause of abdominal pain and often noticed after the complicated, thus it must always be kept in mind in the differential diagnosis.

Full Text Available In recent years, the concept of comprehensive treatment for military trauma has been comprehensively updated. The application of damage control surgery has significantly improved the clinical outcome of severe abdominal injury. With appropriate surgical intervention, post-trauma fluid resuscitation plays an increasingly important role in the treatment of abdominal injury. The damage control resuscitation strategy addresses the importance of permissive hypotension and haemostatic resuscitation for patients with severe trauma, under the guidance of damage control surgical principle.

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.

Background: Abdominal lymphangioma is a rare benign congenital malformation of the mesenteric and/or retroperitoneal lymphatics. Clinical presentation is variable and may be misleading; therefore, complex imaging studies are necessary in the evaluation of this condition. US and CT have a major role in the correct preoperative diagnosis and provide important information regarding location, size, adjacent organ involvement, and expected complications. Objective: To evaluate the clinical and imaging findings of seven children with proven abdominal cystic lymphangioma. Materials and methods: Clinical and imaging files of seven children with pathologically proven abdominal lymphangioma, from three university hospitals, were retrospectively evaluated. Patient's ages ranged from 1 day to 6 years (mean, 2.2 years). Symptoms and signs included evidence of inflammation, abnormal prenatal US findings, chronic abdominal pain, haemorrhage following trauma, clinical signs of intestinal obstruction, and abdominal distension with lower extremities lymphoedema. Plain films of five patients, US of six patients and CT of five patients were reviewed. Sequential imaging examinations were available in two cases. Results: Abdominal plain films showed displacement of bowel loops by a soft tissue mass in five of six patients, two of them with dilatation of small bowel loops. US revealed an abdominal multiloculated septated cystic mass in five of six cases and a single pelvic cyst in one which changed in appearance over 2 months. Ascites was present in three cases. CT demonstrated a septated cystic mass of variable sizes in all available five cases. Sequential US and CT examinations in two patients showed progressive enlargement of the masses, increase of fluid echogenicity, and thickening of walls or septa in both cases, with multiplication of septa in one case. At surgery, mesenteric lymphangioma was found in five patients and retroperitoneal lymphangioma in the other two. Conclusions: US

Trinh, Victoria T; Duckworth, Edward A M

2015-02-01

Background Abdominal fat grafts are often harvested for use in skull base reconstruction and cerebrospinal fluid (CSF) leak repairs, and for operations traversing the nasal sinuses or mastoid bone. Although the endoscopic transnasal surgery has gained significant popularity, in part because it is considered "scarless," a common adjunct, the abdominal fat graft, can result in a disfiguring scar across the abdomen. Objective This is the first report of a scarless abdominal fat graft technique for skull base reconstruction. Methods Ten patients with a median age of 56.5 years (range: 45-73 years) underwent endoscopic transsphenoidal tumor resection with intraumbilical fat graft harvest. Careful circumferential fat dissection at the umbilicus, with progressive retraction of the graft, was crucial to ensure maximal visualization and to prevent injury to the subcutaneous vessels and rectus fascia. Results Following reconstruction of the sellar skull base, all patients did well postoperatively with no evidence of CSF leak. At 12-week follow-up for all patients, there was no evidence of scar, intracavity hematoma, or wound infection. Conclusions Fat graft harvest through an intraumbilical incision results in a scar-free abdominal harvest, and is a useful procedural adjunct to complement "scarless" brain surgery.

Frail patients have decreased physiological reserves and consequently, they are unable to recover as quickly from surgery. Frailty, as an entity, is a risk factor of increased morbidity and mortality. It is also associated with a longer time to discharge. This trial is undertaken to determine if a novel prehabilitation protocol (10-day bundle of interventions-physiotherapy, nutritional supplementation and cognitive training) can reduce the postoperative length of stay of frail patients who are undergoing elective abdominal surgery, compared with standard care. This is a prospective, single-centre, randomised controlled trial with two parallel arms. 62 patients who are frail and undergoing elective abdominal surgery will be recruited and randomised to receive either a novel prehabilitation protocol or standard care. Participants will receive telephone reminders preoperatively to encourage protocol compliance. Data will be collected for up to 30 days postoperatively. The primary outcome of the trial will be the postoperative length of stay and the secondary outcomes are the postoperative complications and functional recovery during the hospital admission. This study has been approved by the Singapore General Hospital Institutional Review Board (CIRB Ref: 2016/2584). The study is also listed on ClinicalTrials.gov (Trial number: NCT02921932). All participants will sign an informed consent form before randomisation and translators will be made available to non-English speaking patients. The results of this study will be published in peer-reviewed journals as well as national and international conferences. The data collected will also be made available in a public data repository.

Full Text Available The emergent abdominal surgeries from either of traumatic or non traumatic causes can result in situations in which the abdominal wall cannot initially be closed. Many techniques have been reported for temporary coverage of the exposed viscera, but the result of various techniques remains unclear. During 94 months, 19 critically ill patients whit an open abdomen underwent surgery using plastic bags (Bogotá bag. The study population comprised of 11 (57.9% male and 8 (42.1% female with an average age of 32.26+14.8 years. The main indications for temporary abdominal coverage were as follows: planned reoperation in 11 (57.9% patients, subjective judgment that the fascia closure is too tight in 6 (31.6% patient's damage control surgery in one patient (5.3% and development of abdominal compartment surgery in one patient (5.3%. Surgical conditions requiring temporary abdominal closure was severe post operative peritonitis in 9 (47.4% patients, post operative intestinal fistula in 4 (21.1% patients, post traumatic intra abdominal bleeding in 3 (15.8% patients and intestinal obstructions in 3 (15.8% patients. Length of hospitalization was 45+23.25 days and the mean total number of laparotomies was 6.2+3.75 times per patient. Three bowel fistulas occurred due to a missed injury at the time of initial operation that was discovered during changing the plastic sheet. They were unrelated to coverage technique. All of them were treated by repair of the defect and serosal patch by adjacent bowel loop. Only one (10.0% patient underwent definitive closure within 6 months of initial operation. The remaining survivor has declined to have hernia repaired. There were 4 (%21.1 early postoperative deaths that were not related to the abdominal coverage technique. Also, there were 5 (26.3% late deaths that were due to dissemination of malignancy with a mean survival time of 20.8+13 (range 2-54 months. Currently 10 patients (52.6% are alive at a follow up of 45 (range 1

Computed tomography findings of early abdominal postoperative complications

Various surgical approaches are used for different abdominal pathological conditions. Postoperative complications occur not infrequently and vary according to the type of the surgery and the clinical context. Nowadays, multidetector computed tomography (MDCT) provides superb anatomic detail and diagnostic accuracy for various intraabdominal pathological processes, even if clinically unsuspected, and it thus has become an essential diagnostic tool for evaluating postoperative insults. Other advantages of abdominal MDCT include its accessibility and its speed, which allow scanning of uncooperative, marginally stable patients. Computed tomography (CT)-guided percutaneous (PC) drainage of postoperative collections is another advantage of CT. Therefore, although CT requires transportation of a critically ill, postoperative patient, it is recommended in any suspicious clinical setting because several conditions require prompt management and a correct diagnosis is crucial. In assessing a patient for suspected postoperative complications, several points should be taken into consideration, including the relevant clinical and laboratory data, the surgical findings, the type of the surgery, the time elapsed since surgery, and the operative technique (either open laparotomy of laparoscopic procedure).

Vomiting, often caused by mechanical intestinal obstruction, is common in dogs. Equivocal radiographic signs often necessitate repeat radiographs or additional imaging procedures. For our prospective, case-controlled, accuracy study, we hypothesized the following: (1) using computed tomography (CT), radiologists will be more sensitive and specific for detecting mechanical intestinal obstruction and recommending surgery compared to using radiographs; and (2) using measurements, radiologists will be more sensitive and specific using radiographs or CT for detecting mechanical intestinal obstruction and recommending surgery. Twenty dogs had abdominal radiographs and abdominal CT. Seventeen dogs had abdominal surgery and three dogs were not obstructed based on clinical follow-up. Confidence levels (five-point scale) of three experienced radiologists for mechanical intestinal obstruction and recommending surgery were recorded before and after making selected measurements. Eight dogs had surgically confirmed mechanical intestinal obstruction, and 12 dogs did not have obstruction. For detecting mechanical intestinal obstruction, CT was more sensitive (95.8% vs. 79.2%) and specific (80.6% vs. 69.4%) compared to radiographs, but the difference was not statistically significant. For recommending surgery, radiography was more sensitive (91.7% vs. 83.3%) and specific (83.3% vs. 72.2%) than using CT, but differences were not statistically significant. We reported objective CT measurements for predicting small mechanical intestinal obstruction. By incorporating these objective data, the diagnosis of mechanical intestinal obstruction changed in five of 120 instances (radiographs and CT). In no instance (0/120), did the objective data change the recommendation for surgery. Using CT or abdominal radiographs for the detection of canine mechanical intestinal obstruction is sensitive and specific when evaluated by experienced veterinary radiologists. © 2016 American College of

Rigor mortis and livor mortis in a living patient: A fatal case of acute total occlusion of the infrarenal abdominal aorta following renal surgery

Directory of Open Access Journals (Sweden)

Høyer Christian Bjerre

2016-06-01

Full Text Available A 63-year-old woman underwent a nephrectomy on the right side for renal cancer. 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.

A Rare Cause of Abdominal Pain in Childhood: Cardiac Angiosarcoma

Directory of Open Access Journals (Sweden)

Elvan Caglar Citak

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.

Building a Simulator with Life-like Realism for Teaching Abdominal Operations.

The objective of this communication is to provide an evolutionary description of an attempt to replicate the success of the Rampahl Cardiac Simulator using perfused abdominal organ blocks the way that the Rampahl Simulator uses ex vivo porcine hearts. This descriptive paper makes no attempt to prove the effectiveness of the described educational tool, but rather, outlines the successes and failures in development. The proven value of a perfused organ teaching tool, as the Rampahl Simulator, suggests that others can build upon the work described in this paper so that, in the future, perfused abdominal organs will be available to students of general surgery as a routine part of their pre-operative preparation. The Animal Resource Facility of the University of Utah, under the oversight of the University Institutional Animal Use and Care Committee (IACUC), provided the animals, operating suites and technical support. During each development phase, General Surgery Residents and Medical Students from all levels participated. In addition, operating room staff with an interest in either medical school or perfusion were invited to participate. The efforts described in this paper eventually resulted in a reliable teaching tool for abdominal procedures in that viability of the porcine abdominal organs for up to three hours after euthanasia was regularly achieved. General Surgery Teaching Programs of a size similar to the University of Utah may have access to the resources necessary to replicate this teaching tool in a cost-effective manner. However smaller teaching programs, such as those without a research facility, may not be able to adapt the procedures described in this paper.

"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 (Psyndrome 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.

Automated segmentation and recognition of abdominal wall muscles in X-ray torso CT images and its application in abdominal CAD

The information of abdominal wall is very important for the planning of surgical operation and abdominal organ recognition. In research fields of computer assisted radiology and surgery and computer-aided diagnosis, the segmentation and recognition of the abdominal wall muscles in CT images is a necessary pre-processing step. Due to the complexity of the abdominal wall structure and indistinctive in CT images, the automated segmentation of abdominal wall muscles is a difficult issue and has not been solved completely. We propose an approach to segment the abdominal wall muscles and divide it into three categories (front abdominal muscles including rectus abdominis; left and right side abdominal muscles including external oblique, internal oblique and transversus abdominis muscles) automatically. The approach, first, makes an initial classification of bone, fat, and muscles and organs based on the CT number. Then a layer structure is generated to describe the 3-D anatomical structures of human torso by stretching the torso region onto a thin-plate for easy recognition. The abdominal wall muscles are recognized on the layer structures using the spatial relations to the skeletal structure and CT numbers. Finally, the recognized regions are mapped back to the 3-D CT images using an inverse transformation of the stretching process. This method is applied to 20 cases of torso CT images and evaluations are based on visual comparison of the recognition results and the original CT images by an expert in anatomy. The results show that our approach can segment and recognize abdominal wall muscle regions effectively. (orig.)

Full Text Available Aim: We investigated total fentanyl dose, its side effects and the quality of Patient Controlled Analgesia (PCA using preemptive paracetamol, lornoxicam and their combination after abdominal surgery. Material and Method: After approval of the Hospital Ethic Committee of Atatürk University, Erzurum, Turkey, The study included 120 ASA I or II, patients aged between 18 to 70 years, scheduled to undergo elective abdominal surgery (midline incision surgery. Patients were randomly divided into four groups. In all cases, anesthesia was induced with 2mg/kg propofol and 0.6mg/kg rocuronium. Anesthesia was maintained by using 1-1.5% sevoflurane in 60% 40% nitrous oxide - O2. Group control (Group C, n=30: received intravenous (i.v. fentanyl through Patient Controlled Analgesia (PCA Group Lornoxicam (Group L, n=30: a one-time 8mg dose of i.v. lornoxicam was added, which was completed approximately 30 minutes before intubation.; Group paracetamol (Group P, n=30: received 1g i.v. paracetamol before intubation, followed by every 6 hours for a total of four times. Group lornoxicam and paracetamol (Group PL, n=30: received 8mg i.v. lornoxicam before intubation, and 1g i.v. paracetamol before intubation every 6 hours for a total of 4 times. During the postoperative 2, 4, 8, 12 and 24 hours, visual analogue scale (VAS, sedation, and nausea-vomiting scores, patient satisfaction, incidence of side effects and total amount of fentanyl used were recorded. Results: Total postoperative fentanyl consumption was significantly higher in GC than of the other groups. At 2, 8, 12, 24. hours, fentanyl consumption was found to be significantly lower in GL than that in GC. In GPL, fentanyl consumption was significantly lower than in GC at all time points. Discussion: We observed that preemptive 8 mg lornoxicam decreased PCA fentanyl consumption but a combination of lornoxicam and paracetamol was not superior to lornoxicam alone.

Abdominal wall Actinomycosis is a rare disease associated with the use of intrauterine device and as a complication of abdominal surgery. Diagnosis is difficult because it is unusual and behaves like a malignant neoplasm. A case report is presented of a patient who had used an intrauterine device for four years and developed a stony tumour in the abdominal wall associated with a set of symptoms that, clinically and radiologically, was simulating a peritoneal carcinomatosis associated with paraneoplastic syndrome, even in the course of an exploratory laparotomy. The patient attended our hospital with a two-month history of abdominal pain and symptoms that mimic a paraneoplastic syndrome. The diagnosis of abdominal actinomycosis was suspected by the finding of the microorganism in cervical cytology together with other cultures and Actinomyces negative in pathological studies, confirming the suspicion of a complete cure with empirical treatment with penicillin. Actinomycosis should be considered in patients with pelvic mass or abdominal wall mass that mimics a malignancy. Antibiotic therapy is the first treatment choice and makes a more invasive surgical management unnecessary. Copyright © 2015 Academia Mexicana de Cirugía A.C. Published by Masson Doyma México S.A.

Surgery for athletic pubalgia usually consists in abdominal wall repair combined with routine bilateral adductor tenotomy. We currently confine the surgical procedure to the injured structure(s) (abdominal wall only, adductor tendon only, or both) to limit morbidity and expedite recovery. Outcomes of this à la carte approach are unclear. The objectives of this retrospective study were to determine the return to play (RTP) time, evaluate the potential influence of injury location, and assess the frequency of recurrence or contralateral involvement. À la carte surgery for athletic pubalgia is associated with similar RTP times as the conventional procedure and is not followed by recurrence. Consecutive adults younger than 40 years of age who underwent surgery for athletic pubalgia with injury to the abdominal wall and/or adductor attachment sites between 2009 and 2015 were included. Patients with intra-articular hip disorders, isolated pubic symphysis involvement, or herniation were not eligible. The diagnosis was established clinically then confirmed by at least one imaging technique (ultrasonography plus either a radiograph of the pelvis or magnetic resonance imaging of the pelvis). The criterion for performing surgery was failure of appropriate conservative therapy followed for at least 3 months. Of the 27 included patients, eight had abdominal wall involvement only, seven adductor tendon involvement only, and 12 both. Overall, 25 (92.6%) patients returned to play at their previous level, after a mean of 112±38 days (range, 53-223 days), and experienced no recurrence during the 1-year follow-up. Mean RTP time was significantly shorter in the group with abdominal wall injury only (91.1±21.0 days) compared to the groups with adductor tendon injury only (101.7±42.0 days) or combined injuries (132.5±39.0) (p=0.02). In patients with athletic pubalgia, à la carte surgery confined to the injured structure(s) produces excellent RTP outcomes. RTP time is shortest in

Post-operative collections are a recognized source of morbidity after abdominal surgery. Percutaneous drainage is currently considered the standard treatment but not all collections are accessible using this method. Since the adoption of EUS, endoscopic transmural drainage has become an attractive option in the management of such complications. The present study aimed to assess the efficacy, safety and modalities of endoscopic transmural drainage in the treatment of post-operative collections. Data of all patients referred to our dedicated multidisciplinary facility from 2014 to 2017 for endoscopic drainage of symptomatic post-operative collections after failure of percutaneous drainage or when it was deemed impossible, were retrospectively analyzed. Thirty-two patients (17 males and 15 females) with a median age of 53 years old (range 31-74) were included. Collections resulted from pancreatic (n = 10), colorectal (n = 6), bariatric (n  = 5), and other type of surgery (n  = 11). Collection size was less than 5 cm in diameter in 10 (31%), between 5 and 10 cm in 17 (53%) ,and more than 10 cm in 5 (16%) patients. The median time from surgery to endoscopic drainage was 38 days (range 6-360). Eight (25%) patients underwent endoscopic guided drainage whereas 24 (75%) patients underwent EUS-guided drainage. Technical success was 100% and clinical success was achieved in 30 (93.4%) after a mean follow-up of 13.5 months (1.2-24.8). Overall complication was 12.5% including four patients who bled following trans-gastric drainage treated with conservative therapy. The present series suggests that endoscopic transmural drainage represents an interesting alternative in the treatment of post-operative collection when percutaneous drainage is not possible or fails.

Extra-abdominal desmoid fibromatosis (EADF) is a benign tumoral condition, classically managed by more or less radical and sometimes mutilating excision. This treatment strategy is associated with a recurrence rate of nearly 50% according to various reports. EADF may show spontaneous stabilization over time. A retrospective series of 26 cases of EADF managed by simple observation was studied to assess spontaneous favorable evolution and identify possible factors impacting evolution. Eleven cases were of primary EADF with no treatment or surgery, and 15 of recurrence after surgery with no adjuvant treatment. MRI was the reference examination during follow-up. Twenty-four cases showed stabilization at a median 14 months; there were no cases of renewed evolution after stabilization. One primary tumor showed spontaneous regression, and one recurrence still showed evolution at end of follow-up (23 months). The sole factor impacting potential for evolution was prior surgery. No radiologic or pathologic criteria of evolution emerged from analysis. The present series, one of the largest dedicated to EADF managed by observation, confirmed recent literature findings: a conservative "wait-and-see" attitude is reasonable and should be considered when large-scale resection would entail significant functional or esthetic impairment.

Evidence-based information on the resumption of daily activities following uncomplicated abdominal surgery is scarce and not yet standardized in medical guidelines. As a consequence, convalescence recommendations are generally not provided after surgery, leading to patients' insecurity, needlessly delayed recovery and prolonged sick leave. The aim of this study was to generate consensus-based multidisciplinary convalescence recommendations, including advice on return to work, applicable for both patients and physicians. Using a modified Delphi method among a multidisciplinary panel of 13 experts consisting of surgeons, occupational physicians and general practitioners, detailed recommendations were developed for graded resumption of 34 activities after uncomplicated laparoscopic cholecystectomy, laparoscopic and open appendectomy, laparoscopic and open colectomy and laparoscopic and open inguinal hernia repair. A sample of occupational physicians, general practitioners and surgeons assessed the recommendations on feasibility in daily practice. The response of this group of care providers was discussed with the experts in the final Delphi questionnaire round. Out of initially 56 activities, the expert panel selected 34 relevant activities for which convalescence recommendations were developed. After four Delphi rounds, consensus was reached for all of the 34 activities for all the surgical procedures. A sample of occupational physicians, general practitioners and surgeons regarded the recommendations as feasible in daily practice. Multidisciplinary convalescence recommendations regarding uncomplicated laparoscopic cholecystectomy, appendectomy (laparoscopic, open), colectomy (laparoscopic, open) and inguinal hernia repair (laparoscopic, open) were developed by a modified Delphi procedure. Further research is required to evaluate whether these recommendations are realistic and effective in daily practice.

ABSTRACT Objectives: to describe the feelings and perceptions resulting from gynecologic surgery by women and analyze how they experience the changes caused by the surgery. Method: a qualitative, descriptive and exploratory study, which had Symbolic Interactionism and Grounded Theory as its theoretical framework. Participants of the study: 13 women submitted to surgery: Total Abdominal Hysterectomy, Total Abdominal Hysterectomy with bilateral Adnexectomy, Wertheim-Meigs surgery, Oophorectomy, Salpingectomy, Mastectomy, Quadrantectomy and Tracheloplasty. Individual interviews were conducted, recorded and analyzed according to the comparative analysis technique of the Grounded Theory. Results: from the data two categories emerged - Perceiving a different body and feeling as a different person and; building the meaning of mutilation. The changes experienced make women build new meanings and change the perception of themselves and their social environment. From the interaction with their inner self, occurred a reflection on relationships, the difference in their body and themselves, the functions it performs and the harm caused by the surgery. Conclusions: the participants felt like different women; the mutilation developed in concrete feelings, due the loss of the organ, and in abstract, linked to the impact of social identity and female functionality. The importance of the nurse establishing a multidimensional care, to identify the needs that go beyond the biological body is perceived. PMID:27579935

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.

To study the clinical presentation and outcome of cases of Abdominal Tuberculosis. Fifty four patients of Abdominal Tuberculosis were seen during the study period. Four patients were lost to follow-up, which were excluded. Detailed information of all the patients including age, sex, symptoms, signs, investigations and management was recorded, analyzed and compared with local and international data. Out of the 50 patients with Abdominal Tuberculosis, 31 were females and 19 males. Their ages ranged from 17 to 63 years, with a mean age of 25.1 years. Thirty five cases were admitted through Emergency and 15 through Outpatients departments. Abdominal pain was the most common symptom found in 44 (88%) patients followed by vomiting in 33 (66%). Abdominal tenderness was seen in 22 (44%) patients, while 16 (32%) patients had rigidity and other features of peritonitis. Surgery was performed in all these patients, limited right hemicolectomy in 17 (34%), segmental resection and anastomosis in 12 (24%), ileostomy and strictureplasty in six (12%) each, repair of perforation in five (10%) and adhesiolysis in four (8%) patients. Overall mortality was 8% due to septicaemia and multiorgan failure. Abdominal Tuberculosis is a significant clinical entity with lethal complications in neglected cases. It affects a younger age group and is more common in females. Clinical features are rather non-specific but vague ill health, low grade fever, weight loss and anorexia may help to diagnose the case.

Techniques for Abdominal Wall Closure after Damage Control Laparotomy: From Temporary Abdominal Closure to Early/Delayed Fascial Closure—A Review

Full Text Available Open abdomen (OA has been an effective treatment for abdominal catastrophes in traumatic and general surgery. However, management of patients with OA remains a formidable task for surgeons. The central goal of OA is closure of fascial defect as early as is clinically feasible without precipitating abdominal compartment syndrome. Historically, techniques such as packing, mesh, and vacuum-assisted closure have been developed to assist temporary abdominal closure, and techniques such as components separation, mesh-mediated traction, bridging fascial defect with permanent synthetic mesh, or biologic mesh have also been attempted to achieve early primary fascial closure, either alone or in combined use. The objective of this review is to present the challenges of these techniques for OA with a goal of early primary fascial closure, when the patient’s physiological condition allows.

Multi-organ segmentation from CT images is an essential step for computer-aided diagnosis and surgery planning. However, manual delineation of the organs by radiologists is tedious, time-consuming and poorly reproducible. Therefore, we propose a fully automatic method for the segmentation of multiple organs from three-dimensional abdominal CT images. The proposed method employs deep fully convolutional neural networks (CNNs) for organ detection and segmentation, which is further refined by a time-implicit multi-phase evolution method. Firstly, a 3D CNN is trained to automatically localize and delineate the organs of interest with a probability prediction map. The learned probability map provides both subject-specific spatial priors and initialization for subsequent fine segmentation. Then, for the refinement of the multi-organ segmentation, image intensity models, probability priors as well as a disjoint region constraint are incorporated into an unified energy functional. Finally, a novel time-implicit multi-phase level-set algorithm is utilized to efficiently optimize the proposed energy functional model. Our method has been evaluated on 140 abdominal CT scans for the segmentation of four organs (liver, spleen and both kidneys). With respect to the ground truth, average Dice overlap ratios for the liver, spleen and both kidneys are 96.0, 94.2 and 95.4%, respectively, and average symmetric surface distance is less than 1.3 mm for all the segmented organs. The computation time for a CT volume is 125 s in average. The achieved accuracy compares well to state-of-the-art methods with much higher efficiency. A fully automatic method for multi-organ segmentation from abdominal CT images was developed and evaluated. The results demonstrated its potential in clinical usage with high effectiveness, robustness and efficiency.

Carotid and coronary disease management prior to open and endovascular aortic surgery. What are the current guidelines?

Science.gov (United States)

Thompson, J P

2014-04-01

Several bodies produce broadly concurring and updated guidelines for the evaluation and treatment of cardiovascular disease in both surgical and non-surgical patients. Recent developments include revised recommendations on preoperative stress testing, referral for possible coronary revascularization and medical management. It is recognized that non-invasive cardiac tests are relatively poor at predicting perioperative risk, and "prophylactic" coronary revascularization has a limited role. The planned aortic intervention (open or endovascular repair) also influences preoperative management. Patients presenting for elective abdominal aortic aneurysm (AAA) repair should only be referred for cardiological testing if they have active symptoms of coronary artery disease (CAD), known CAD and poor functional exercise capacity, or multiple risk factors for CAD. Coronary revascularization before AAA surgery should be limited to patients with established indications, so cardiac stress testing should only be performed if it would change management i.e. the patient is a candidate for and would benefit from coronary revascularization. When endovascular aortic repair is planned, it is reasonable to proceed to surgery without further cardiac stress testing or evaluation unless otherwise indicated. All non-emergency patients require medical optimization, but perioperative beta blockade benefits only certain patients. Some of the data informing recent guidelines have been questioned and some guidelines are being revised. Current guidelines do not specifically address the management of patients with known or suspected carotid artery disease who may require aortic surgery. For these patients, an individualized approach is required. This review considers recent guidelines. Algorithms for investigation and management based on their recommendations are included.

An Intra-Abdominal Desmoid Tumor, Embedded in the Pancreas, Preoperatively Diagnosed as an Extragastric Growing Gastrointestinal Stromal Tumor

Mari Mizuno

Full Text Available A 45-year-old woman was found to have a pancreatic tumor by abdominal ultrasound performed for a medical check-up. Abdominal contrast-enhanced computed tomography showed a hypovascular tumor measuring 30 mm in diameter in the pancreatic tail. Endoscopic ultrasound-guided fine needle aspiration was performed. An extragastric growing gastrointestinal stromal tumor was thereby diagnosed preoperatively, and surgical resection was planned. Laparoscopic surgery was attempted but conversion to open surgery was necessitated by extensive adhesions, and distal pancreatectomy, splenectomy, and partial gastrectomy were performed. The histological diagnosis was an intra-abdominal desmoid tumor. A desmoid tumor is a fibrous soft tissue tumor arising in the fascia and musculoaponeurotic tissues. It usually occurs in the extremities and abdominal wall, and only rarely in the abdominal cavity. We experienced a case with an intra-abdominal desmoid tumor that was histologically diagnosed after laparotomy, which had been preoperatively diagnosed as an extragastric growing gastrointestinal stromal tumor. Although rare, desmoid tumors should be considered in the differential diagnosis of intra-abdominal tumors. Herein, we report this case with a literature review.

Postoperative hemorrhage is a significant cause of morbidity and mortality following liver resection. It typically presents early within the postoperative period, and conservative management is possible in the majority of cases. We present a case of late post-hepatectomy hemorrhage associated with overt abdominal compartment syndrome resulting from a localized functional compartment within the abdomen. A 68-year-old white man was readmitted with sudden onset of upper abdominal pain, vomiting, and hemodynamic instability 8 days after an uneventful hepatic resection for metachronous colon cancer metastasis. A frozen abdomen with adhesions due to complicated previous abdominal surgeries was encountered at the first intervention, but the surgery itself and initial recovery were otherwise unremarkable. Prompt response to fluid resuscitation at admission was followed by a computed tomography of his abdomen that revealed active arterial hemorrhage in the liver resection site and hemoperitoneum (estimated volume abdominal compartment syndrome. Surgical exploration confirmed a small volume of ascites and blood clots (1.2 L) under significant pressure in his supramesocolic region, restricted by his frozen lower abdomen, which we evacuated. Dramatic improvement in his ventilatory pressure was immediate. His abdomen was left open and a negative pressure device was placed for temporary abdominal closure. The fascia was formally closed after 48 hours. He was discharged home at postoperative day 6. Intra-abdominal pressure and radiologic findings of intra-abdominal hemorrhage should be carefully interpreted in patients with extensive intra-abdominal adhesions. A high index of suspicion and detailed understanding of abdominal compartment mechanics are paramount for the timely diagnosis of abdominal compartment syndrome in these patients. Clinicians should be aware that abnormal anatomy (such as adhesions) coupled with localized pathophysiology (such as hemorrhage) can create a so

The transversus abdominal plane (TAP) block has been described as an effective pain control technique after abdominal surgery. We performed a systematic review and meta-analysis of randomized-controlled trials (RCTs) to account for the increasing number of TAP block studies appearing in the literature. The primary outcome we examined was the effect of TAP block on the postoperative pain score at six, 12, and 24 hr. The secondary outcome was 24-hr morphine consumption. We searched the United States National Library of Medicine database, the Excerpta Medica database, and the Cochrane Central Register of Controlled Clinical Studies and identified RCTs focusing on the analgesic efficacy of TAP block compared with a control group [i.e., placebo, epidural analgesia, intrathecal morphine (ITM), and ilioinguinal nerve block after abdominal surgery]. Meta-analyses were performed on postoperative pain scores at rest at six, 12, and 24 hr (visual analogue scale, 0-10) and on 24-hr opioid consumption. In the 51 trials identified, compared with placebo, TAP block reduced the VAS for pain at six hours by 1.4 (95% confidence interval [CI], -1.9 to -0.8; P consumption at 24 hr after surgery (mean difference, -14.7 mg; 95% CI, -18.4 to -11.0; P consumption in the TAP block group after gynecological surgery, appendectomy, inguinal surgery, bariatric surgery, and urological surgery. Nevertheless, separate analysis of the studies comparing ITM with TAP block revealed that ITM seemed to have a greater analgesic efficacy. The TAP block can play an important role in the management of pain after abdominal surgery by reducing both pain scores and 24-hr morphine consumption. It may have particular utility when neuraxial techniques or opioids are contraindicated.

Clinical application of PET in abdominal cancers

Clinical application of positron emission tomography (PET) is rapidly increasing for the detection and staging of cancer at whole-body studies performed with the glucose analogue tracer 2-[fluorine-18]fluoro-2-deoxy-D-glucose (FG). Although FDG PET cannot match the anatomic resolution of conventional imaging techniques in the liver and the other abdominal organs, it is particularly useful for identification and characterization of the entire body simultaneously. FDG PET can show foci of metastatic disease that may not be apparent at conventional anatomic imaging and can aid in the characterizing of indeterminate soft-tissue masses. Most abdominal cancer requires surgical management. FGD PET can improve the selection of patients for surgical treatment and thereby reduce the morbidity and mortality associated with inappropriate surgery. FDG PET is also useful for the early detection of recurrence and the monitoring of therapeutic effect. The abdominal cancers, such as gastroesophageal cancer, colorectal cancer, liver cancer and pancreatic cancer, are common malignancies in Korea, and PET is one of the most promising and useful methodologies for the management of abdominal cancers

A good patient-surgeon relationship relies on adequate preoperative education and counseling. Several multimedia resources, such as web-based education tools, have become available to enhance aspects of perioperative care. The purpose of this study was to evaluate the effect of an interactive web-based education tool on perioperative patient satisfaction scores after outpatient orthopaedic surgery. It was hypothesized that web-based education prior to outpatient orthopaedic surgery enhances patient satisfaction scores. Randomized controlled trial; Level of evidence, 1. All patients undergoing knee arthroscopy with meniscectomy, chondroplasty, or anterior cruciate ligament reconstruction or shoulder arthroscopy with rotator cuff repair were eligible for inclusion and were randomized to the study or control group. The control group received routine education by the surgeon, whereas the study group received additional web-based education. At the first postoperative visit, all patients completed the OAS CAHPS (Outpatient and Ambulatory Surgery Consumer Assessment of Healthcare Providers and Systems) survey. Differences in patient satisfaction scores between the study and control groups were determined with an independent t test. A total of 177 patients were included (104 [59%] males; mean age, 42 ± 14 years); 87 (49%) patients were randomized to receive additional web-based education. Total patient satisfaction score was significantly higher in the study group (97 ± 5) as compared with the control group (94 ± 8; P = .019), specifically for the OAS CAHPS core measure "recovery" (92 ± 13 vs 82 ± 23; P = .001). Age, sex, race, workers' compensation status, education level, overall health, emotional health, procedure type and complexity, and addition of a video did not influence patient satisfaction scores. Supplemental web-based patient education prior to outpatient orthopaedic surgery enhances patient satisfaction scores.

Full Text Available BACKGROUND Blunt abdominal trauma is an emergency and is associated with significant morbidity and mortality. The aim of the study is to study incidence, demographic profile, epidemiological factors, mechanism of trauma, treatment modalities, associated injuries, postoperative complications and morbidity and mortality. MATERIALS AND METHODS A retrospective analysis of 72 patients of blunt abdominal trauma who were admitted in government general hospital between May 2013 to April 2015 in Department of General Surgery, Government General Hospital, Guntur, with in a span of 24 months were studied. Demographic data, mechanism of trauma, management and outcome were studied. RESULTS Most of the patients in our study were in the age group of 21-30 years. Spleen was the commonest organ involved and most common procedure performed was splenectomy. Most common extra-abdominal injury was rib fractures. Wound infection was the commonest complication. CONCLUSION Initial resuscitative measures, thorough clinical examination and correct diagnosis forms the vital part of the management. FAST is more useful in blunt abdominal trauma patients who are unstable. X-ray revealed 100% accuracy in hollow viscous perforation in blunt abdominal trauma patients. CT abdomen is more useful in stable patients. Definitive indication for laparotomy was haemodynamic instability and peritonitis. Associated injuries influenced morbidity and mortality. Early diagnosis and prompt treatment can save many lives.

Intra-abdominal infections are a common problem for the general surgeon and major sources of morbidity and mortality in the intensive care unit. Some of these patients present with peritonitis that can rapidly progress to septic shock. The basic principles of care include prompt resuscitation, antibiotics, and source control. This article will use a detailed case study to outline the management of a patient with severe intra-abdominal infection from diverticulitis from initial resuscitation to reconstruction. Components of the Surviving Sepsis Campaign as they pertain to surgical patients are discussed and updated, and the concept of damage control general surgery is applied. Copyright © 2012.

This multicenter prospective study aimed to assess the utility of dynamic enhanced magnetic resonance imaging (MRI) prior to breast-conserving surgery for breast cancer. The research subjects were drawn from patients with primary early resectable breast cancer treated in the breast disease centers of six three-level hospitals in Beijing from 1 January 2010 to 31 December 2012. The participants were allocated to a breast-conserving surgery group (breast-conserving group) or a total mastectomy group (total mastectomy group). Enhanced MRI was used to measure breast volume, longest diameter of tumor and tumor volume. The correlations between these measurements and those derived from histopathologic findings were assessed. The relationships between the success rate of breast-conserving surgery and MRI- and pathology-based measurement results were statistically analyzed in the breast-conserving group. The study included 461 cases in the total mastectomy group and 195 in the breast-conserving group. Allocation to these groups was based on clinical indications and patient preferences. The cut-off for concurrence between MRI- and pathology-based measurements of the longest diameter of tumor was set at 0.3 cm. In the total mastectomy group, the confidence interval for 95% concurrence of these measurements was 35.41%-44.63%. Correlation coefficients for MRI and histopathology-based measurements of breast volume, tumor volume and tumor volume/breast volume ratio were r = 0.861, 0.569, and 0.600, respectively (all P surgery were 100% and 88.54%, respectively. There were significant correlations between dynamic enhanced MRI- and histopathology-based measurements of the longest diameter of breast lesions, breast and tumor volumes, and breast volume/tumor volume ratios. Preoperative MRI examination improves the success rate of breast-conserving surgery.

The incidence of depression and anxiety is higher in patients with acute coronary syndrome. The aim of this study is to determine whether experiencing acute coronary syndrome prior to open heart surgery affects patients in terms of depression, hopelessness, anxiety, fear of death and quality of life. The study included 63 patients who underwent coronary bypass surgery between January 2015 and January 2016. The patients were divided into two groups: those diagnosed after acute coronary syndrome (Group 1) and those diagnosed without acute coronary syndrome (Group 2). Beck depression scale, Beck hopelessness scale, Templer death anxiety scale and death depression scale, State-Trait anxiety inventory and WHOQOL-Bref quality of life scale were applied. There was no significant difference between the two groups in terms of the total score obtained from Beck depression scale, Beck hopelessness scale - future-related emotions, loss of motivation, future-related expectations subgroups, death anxiety scale, the death depression scale, State-Trait Anxiety Inventory - social and environmental subgroups. The mental quality of life sub-scores of group 2 were significantly higher. The patients in both groups were found to be depressed and hopeless about the future. Anxiety levels were found to be significantly higher in all of the patients in both groups. Acute coronary syndrome before coronary artery bypass surgery impairs more the quality of life in mental terms. But unexpectedly there are no differences in terms of depression, hopelessness, anxiety and fear of death.

Placement of a drain following abdominal surgery is common despite a lack of convincing evidence in the current literature to support this practice. The use of intra-abdominal drain is associated with many potential and serious complications. We report a drain site evisceration of the right fallopian tube after the removal of an intra-abdominal drain. The drain was placed in the right iliac fossa in a patient who underwent a lower segment Caesarean section (LSCS) for meconium liquor with fetal distress. The Pfannenstiel incision made for LSCS was reopened and the protruding inflamed fimbrial end of the right fallopian tube was excised. The patient made an uneventful recovery. Routine intra-abdominal prophylactic drain following an abdominal surgery including LSCS should be discouraged.

Unexplained abdominal pain is a common but difficult presenting feature faced by the clinicians. Such patients can undergo a number of investigations with failure to reach any diagnosis. The objective of this study was to evaluate the use of laparoscopy in the diagnosis and management of patients with unexplained abdominal pain. Methods: This cross-sectional study was conducted at Pakistan Institute of Medical Sciences Islamabad from January 2009 to December 2013. This study included 91 patients of unexplained abdominal pain not diagnosed by routine clinical examination and investigations. These patients were subjected to diagnostic laparoscopy for evaluation of their conditions and to confirm the diagnosis. These patients presented 43% of patients undergoing investigations for abdominal pain. Patients diagnosed with gynaecological problems were excluded to see surgeon's perspective. The findings and the outcomes of the laparoscopy were recorded and data was analyzed. Results: Unexplained abdominal pain is common in females than in males. The most common laparoscopic findings were abdominal tuberculosis followed by appendicitis. Ninety percent patients achieved pain relief after laparoscopic intervention. Conclusion: Laparoscopy is both beneficial and safe in majority of patients with unexplained abdominal pain. General surgeons should acquire training and experience in laparoscopic surgery to provide maximum benefit to these difficult patients. (author)

Many minimally invasive surgical procedures and assisting robotic systems have been developed to further minimize the number and size of incisions in the body surface. This paper presents a new idea combining the advantages of modular robotic surgery, single incision laparoscopic surgery and needlescopic surgery. In the proposed concept, modules carrying therapeutic or diagnostic tools are inserted in the abdominal cavity from the navel as in single incision laparoscopic surgery and assembled to 3-mm needle shafts penetrating the abdominal wall. A three degree-of-freedom robotic module measuring 16 mm in diameter and 51 mm in length was designed and prototyped. The performance of the three connected robotic modules was evaluated. A new idea of modular robotic surgery was proposed, and demonstrated by prototyping a 3-DOF robotic module. The performance of the connected robotic modules was evaluated, and the challenges and future work were summarized.

The aim of our study is to investigate the effect of two different methods of continuous positive airway pressure (CPAP) and bilevel positive airway pressure (BIPAP) and oxygen support under spontaneous ventilation on respiration mechanics, gas exchange, dry mouth and face mask lesion during an early postoperative period in patients undergoing upper abdominal surgery. Eighty patients undergoing elective abdominal surgery with laparotomy, between the age of 25 and 75 years and American Society of Anesthesiologists Physical Status score (ASA) II-III with chronic obstructive pulmonary disease (COPD) diagnosis were included to the study. Subjects were randomly allocated in to four groups. During the first postoperative hour, the first group received BIPAP, second group received high-flow CPAP, third group received low-flow CPAP and fourth group received deep breathing exercises, respiratory physiotherapy and O2 therapy. Preoperative, postoperative before and after treatment PaO2, PaCO2, SpO2, tidal volume (TV), respiratory rate (RR) levels were recorded. Subjects with dry mouth or face mask lesion were recorded. In all groups, PaO2 and TV measurements were higher at the postoperative first hour than the postoperative zero hour. We found that low-flow CPAP increased PaO2 and SpO2 values more, and TV levels were higher in the postoperative period than the preoperative period. PaCO2 levels were elevated at the zero hour postoperatively and at the end of the first hour; they decreased approximately to preoperative values, except in the fourth group. Administration of prophylactic respiratory support can prevent the deterioration of pulmonary functions and hypoxia in patients with COPD undergoing upper abdominal surgery. In addition, we found that low-flow CPAP had better effects on PaO2, SpO2, TV compared to other techniques.

Abdominal Splenosis Mimicking Hepatic Tumor: A Case Report

2008-11-01

Full Text Available Diagnosis of abdominal splenosis is often undiagnosed until treatment for splenic rupture or splenectomy. This report describes a patient with splenosis mimicking hepatic tumor. The patient had a history of splenic trauma with splenectomy and chronic hepatitis C. After routine abdominal ultrasound revealed a liver nodule, further imaging studies, including magnetic resonance imaging, computed tomography and angiography, were performed. After the patient eventually underwent surgery, pathology revealed splenic tissue. Despite its distinguishable clinical features, splenosis is difficult to identify by modern imaging modalities. Therefore, accurate and timely diagnosis of this disease requires constant vigilance.

Two main causes for nutrient deficiencies following bariatric surgery (BS) are pre-operative deficiencies and favoring foods with high-energy density and poor micronutrient content. The aims of this study were to evaluate nutritional status and gender differences and the prevalence of nutritional deficiencies among candidates for laparoscopic sleeve gastrectomy (LSG) surgery. A cross-sectional analysis of pre-surgery data collected as part of a randomized clinical trial on 100 morbidly obese patients with non-alcoholic fatty liver disease (NAFLD) admitted to LSG surgery at Assuta Medical Center between February 2014 and January 2015. Anthropometrics, food intake, and fasting blood tests were evaluated during the baseline visit. One-hundred patients completed the pre-operative measurements (60 % female) with a mean age of 41.9 ± 9.8 years and a mean BMI of 42.3 ± 4.7 kg/m(2). Pre-operatively, deficiencies for iron, ferritin, folic acid, vitamin B1, vitamin B12, vitamin D, and hemoglobin were 6, 1, 1, 6, 0, 22, and 6 %, respectively. Pre-surgery, mean energy, protein, fat, and carbohydrate intake were 2710.7 ± 1275.7 kcal/day, 114.2 ± 48.5, 110.6 ± 54.5, and 321.6 ± 176.1 gr/day, respectively. The intakes for iron, calcium, folic acid, vitamin B12, and vitamin B1 were below the Dietary Reference Intake (DRI) recommendations for 46, 48, 58, 14, and 34 % of the study population, respectively. We found a low prevalence of nutritional deficiencies pre-operatively except for vitamin D. Most micronutrient intake did not reach the DRI recommendations, despite high-caloric and macronutrient intake indicating a poor dietary quality.

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

Lumbar surgery is regularly applied in cases of discal hernia and acquired lumbar stenosis. In this report, we present a case of a laceration in the left common iliac artery and iliac vein during a lumbar surgery and discuss the literature concerning this kind of event. In the present case, the surgical procedure was followed by a sudden decrease in blood pressure, and the surgeon discovered an intra-abdominal haemorrhage that led to the patient's death. Postmortem investigation confirmed the intra-abdominal haemorrhage and revealed a laceration of the proximal portion of the left common iliac artery and left iliac vein. The source of bleeding could be detected especially thanks to multi-phase postmortem CT angiography (MPMCTA), which was performed prior to autopsy. We also found a haemorrhagic path through the intervertebral disc between the L4-L5 vertebrae, caused by the surgeon's instrument (pituitary rongeur). To date, a few cases have been described of iatrogenic death resulting from a tear in the iliac vessels during lumbar surgery, but not from the postmortem perspective. Such investigations have recently been modernized thanks to the introduction of forensic imaging. In particular, MPMCTA offers new possibilities in postmortem investigations and can be considered the new gold standard for investigating deaths related to medical intervention. Here we describe the first case of a death during lumbar surgery using this new method. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Abdominal wall leiomyoma arising de novo is very rare, hence the reported imaging findings of this disease are also rare. We reported the case of a 33-year-old woman who presented with an abdominal wall mass without antecedent gynecological surgeries. The initial abdominal computed tomography (CT) showed thickening of the left rectus abdominis and the loss of intervening fat between the rectus abdominis and the lateral abdominal muscles. After 8 months, the follow-up contrast-enhanced CT and ultrasonography (US) showed a lentiform-shaped mass with isodensity to the adjacent muscles. The US-guided biopsy was consistent with leiomyoma

Persistent variation in practice surrounds preoperative clopidogrel management at the time of vascular surgery. While some surgeons preferentially discontinue clopidogrel citing a perceived risk of perioperative bleeding, others will proceed with surgery in patients taking clopidogrel for an appropriate indication. The purpose of this study was to determine whether preoperative clopidogrel use was associated with significant bleeding complications during peripheral arterial surgery. We reviewed a prospective regional vascular surgery registry recorded by 66 surgeons from 15 centers in New England from 2003 to 2009. Preoperative clopidogrel use within 48 hours of surgery was analyzed among patients undergoing carotid endarterectomy (CEA), lower extremity bypass (LEB), endovascular abdominal aortic aneurysm repair (EVAR), and open abdominal aortic aneurysm repair (oAAA). Ruptured AAAs were excluded. Endpoints included postoperative bleeding requiring reoperation, as well as the incidence and volume of blood transfusion. Statistical analysis was performed using analysis of variance, Fisher exact, χ(2), and Wilcoxon rank-sum tests. Over the study interval, a total of 10,406 patients underwent surgery, including 5264 CEA, 2883 LEB, 1125 EVAR, and 1134 oAAA repair. Antiplatelet use among all patients varied, with 19% (n = 2010) taking no antiplatelet agents, 69% (n = 7132) taking aspirin (ASA) alone, 2.2% (n = 229) taking clopidogrel alone, and 9.7% (n = 1017) taking both ASA and clopidogrel. Clopidogrel alone or as dual antiplatelet therapy was most frequently used prior to CEA and least frequently prior to oAAA group (CEA 16.1%, LEB 9.0%, EVAR 6.5%, oAAA 5%). Reoperation for bleeding was not significantly different among patients based on antiplatelet regimen (none 1.5%, ASA 1.3%, clopidogrel 0.9%, ASA/clopidogrel 1.5%, P = .74). When analyzed by operation type, no difference in reoperation for bleeding was seen across antiplatelet regimens. There was also no

Canine cryptococcosis cases are typically reported as neurologic, disseminated, or both. There have been few reports of other parenchymal organ involvement. Dogs infected with Cryptococcus spp. are likely to develop central nervous system involvement, and those that are severely affected are treated aggressively with surgery and/or amphotericin B. This report describes two cases of canine abdominal cryptococcosis: one boxer with primary alimentary cryptococcosis alone and one miniature schnauzer with pancreatic and disseminated cryptococcosis. The boxer is unique in that the dog suffered from primary alimentary cryptococcosis without dissemination, secondary anemia due to gastrointestinal losses, and is the second case to have Cryptococcus spp. identified on fecal examination as part of the diagnostic workup. Unlike previous reports, surgery was not performed in either case, and both dogs were treated with fluconazole alone. Currently, both dogs are free from clinical signs, and Cryptococcus spp. antigen titers are negative at 17 and 15 mo after initial presentation. These cases suggest fluconazole may be effective therapy alone for canine abdominal cryptococcosis, negating the need for high-risk therapy options such as surgery and/or amphotericin B in some cases.

Over 9.6 million ED visits occur annually for abdominal pain in the US, but little is known about the medical outcomes of these patients based on demographics. We aimed to identify disparities in outcomes among children presenting to the ED with abdominal pain linked to race and SES. Data from 4.2 million pediatric encounters of abdominal pain were analyzed from 43 tertiary US children's hospitals, including 2.0 million encounters in the emergency department during 2004-2011. Abdominal pain was categorized as functional or organic abdominal pain. Appendicitis (with and without perforation) was used as a surrogate for abdominal pain requiring emergent care. Multivariate analysis estimated likelihood of hospitalizations, radiologic imaging, ICU admissions, appendicitis, appendicitis with perforation, and time to surgery and hospital discharge. Black and low income children had increased odds of perforated appendicitis (aOR, 1.42, 95% CI, 1.32- 1.53; aOR, 1.20, 95% CI 1.14 - 1.25). Blacks had increased odds of an ICU admission (aOR, 1.92, 95% CI 1.53 - 2.42) and longer lengths of stay (aHR, 0.91, 95% CI 0.86 - 0.96) than Whites. Minorities and low income also had lower rates of imaging for their appendicitis, including CT scans. The combined effect of race and income on perforated appendicitis, hospitalization, and time to surgery was greater than either separately. Based on race and SES, disparity of health outcomes exists in the acute ED setting among children presenting with abdominal pain, with differences in appendicitis with perforation, length of stay, and time until surgery.

INTRODUCTION Reporting surgeons' outcomes has recently been introduced in the UK. This has the potential to result in surgeons becoming risk averse. The aim of this study was to investigate whether reporting outcomes for abdominal aortic aneurysm (AAA) surgery impacts on the number and risk profile (level of fitness) of patients offered elective treatment. METHODS Publically available National Vascular Registry data were used to compare the number of AAAs treated in those centres across the UK that reported outcomes for the periods 2008-2012, 2009-2013 and 2010-2014. Furthermore, the number and characteristics of patients referred for consideration of elective AAA repair at a single tertiary unit were analysed yearly between 2010 and 2014. Clinic, casualty and theatre event codes were searched to obtain all AAAs treated. The results of cardiopulmonary exercise testing (CPET) were assessed. RESULTS For the 85 centres that reported outcomes in all three five-year periods, the median number of AAAs treated per unit increased between the periods 2008-2012 and 2010-2014 from 192 to 214 per year (p=0.006). In the single centre cohort study, the proportion of patients offered elective AAA repair increased from 74% in 2009-2010 to 81% in 2013-2014, with a maximum of 84% in 2012-2013. The age, aneurysm size and CPET results (anaerobic threshold levels) for those eventually offered elective treatment did not differ significantly between 2010 and 2014. CONCLUSIONS The results do not support the assumption that reporting individual surgeon outcomes is associated with a risk averse strategy regarding patient selection in aneurysm surgery at present.

To evaluate the effects of music listening on pain intensity and pain distress on the first and second postoperative days in abdominal surgery patients and the long-term effects of music on the third postoperative day. Music has been found to relieve pain intensity in surgery patients. There are only a few studies on music intervention in abdominal surgery. Music intervention studies assessing multidimensional pain such as pain intensity and pain distress are also scarce. Prospective clinical study with two parallel groups. Patients undergoing elective abdominal surgery (n = 168) were divided into either a music group (n = 83) or a control group (n = 85). Patients assessed pain intensity and pain distress in bed rest, during deep breathing and in shifting position once in the evening of the operation day and on the first and second postoperative days in the morning, at noon and in the evening. On the third postoperative day, the patients assessed their pain intensity and pain distress only once. In the music group, the patients' pain intensity and pain distress in bed rest, during deep breathing and in shifting position were significantly lower on the second postoperative day compared with control group of patients. On the third postoperative day, when long-term effects of music on pain intensity and pain distress were assessed, there were no significant differences between music and control groups. This study demonstrates that the use of music alleviates pain intensity and pain distress in bed rest, during deep breathing and in shifting position after abdominal surgery on the second postoperative day. Music intervention is safe, inexpensive and easily used to improve the healing environment for abdominal surgery patients. Music intervention should be offered as an adjunct alternative to pharmacological pain relief after abdominal surgery in nursing practice. © 2011 Blackwell Publishing Ltd.

The aim of this study was to describe the CT features of abdominal plasma cell neoplasms. We reviewed CT imaging findings in 11 patients (seven men, four women; mean age 62 years) with plasma cell neoplasms and abdominal involvement. Helical CT of the entire abdomen and pelvis was performed following intravenous administration of contrast material. Images were analyzed in consensus by two radiologists. Diagnoses were made from biopsy, surgery and/or clinical follow-up findings. Multiple myeloma was found in seven patients and extramedullary plasmacytoma in four patients. All patients with multiple myeloma had multifocal disease with involvement of perirenal space (4/7), retroperitoneal and pelvic lymph nodes (3/7), peritoneum (3/7), liver (2/7), subcutaneous tissues (2/7) and kidney (1/7). In three of the four patients with extramedullary plasmacytoma, a single site was involved, namely stomach, vagina and retroperitoneum. In the fourth patient, a double site of abdominal involvement was observed with rectal and jejunal masses. Plasma cell neoplasm should be considered in the differential diagnosis of single or multiple enhancing masses in the abdomen or pelvis. Abdominal plasma cell neoplasms were most frequently seen as well-defined enhancing masses (10/11). (orig.)

Twenty six patients were studied with 67 Gallium to detect and localize the site of intra-abdominal and intraperitoneal infection. They were divided in two groups: a) with and b) without physical symptoms that could localize an abcess in the abdominal cavity. All the patients with suppuration had persistent up-take of 67 Ga in one anatomic area of the abdomen, subsequently documented by computarized axial tomography (CAT) in 58% of the cases or by laparotomy in 88% of them. Scintigraphy with 67 Ga in the patients with recent surgery not only detected focal infection in 67% of the cases but excluded subphernic collection. In 78% of patients with prolonged fever, the infection was localized. There was no false positive result. The comparison in 56% of the cases with CAT demonstrated that both techniques are 100% sensitive for the diagnosis of abdominal suppurative processes. Three of the 26 patients, after six weeks of medical treatment, were restudied with 67 Ga and CAT, showing total resolution of their previous abnormalities. It is concluded that 67 Ga scintigraphy performed as the first study in febrile patients independent of the presence or absence of physical symptoms that could localize the abdominal infection, is sensitive for the detection and localization of an abdominal abscess and that a negative result excludes it.

Despite progress in surgical techniques and modern medical treatment, postoperative complications occur not infrequently and vary according to type of surgery, clinical setting, and time elapsed since surgery. In general, they can be divided into early and delayed complications. Delayed postoperative complications can be classified as specific and nonspecific. The common nonspecific delayed complications are incisional hernia and postoperative bowel obstruction. Bowel obstruction can be further categorized as obstruction related to benign or neoplastic etiology, the latter occurring in oncology patients in whom the primary surgery was related to an underlying abdominal neoplasm. Gossypiboma is another, fortunately rare, postoperative complication. Specific complications appear after specific operations and include the following: Splenosis - following splenectomy. Retained gallstones and spilled gallstones - following cholecystectomy, mainly laparoscopic. Dropped appendicolith and stump appendicitis - following appendectomy, mainly laparoscopic. Obturation obstruction by a bezoar - following gastric surgery. Afferent loop syndrome (ALS) - following Bilroth II gastrectomy. (author)

Objective: To investigate CT findings of concealed rupture of intestine following abdominal trauma. Methods: CT findings of 11 cases with concealed rupture of intestine following abdominal trauma proved by surgery were identified retrospectively. Results: The main special signs included: (1) Free air in 4 cases, mainly around injured small bowel or under the diaphragm, or in the retroperitoneal space or and in the lump. (2) High density hematoma between the intestines or in the bowel wall (4 cases). (3) Bowel wall injury sign, demonstrated as low density of the injured intestinal wall, attenuated locally but relatively enhanced in neighbor wall on enhanced CT. (4) Lump around the injured bowel wall with obvious ring-shaped enhancement (4 cases). Other signs included: (1) Free fluid in the abdominal cavity or between the intestines with blurred borders. (2) Bowel obstruction. Conclusion: CT is valuable in diagnosing concealed rupture of intestine following abdominal trauma. (authors)

Background Intra-abdominal adhesion is one of the most common complications after abdominal surgery. The efficacy of current treatments for intra-abdominal adhesion is unsatisfactory. In this study, we investigated the effect of gallic acid on the prevention and treatment of intra-abdominal adhesions after abdominal surgery using an intra-abdominal adhesion rat model. Material/Methods The experimental rats were randomly divided into the sham operation group, the control group, the chitosan group, and 3 gallic acid groups of different concentrations. All rats except those in the sham operation group received cecal abrasion to induce adhesion. From the first postoperative day, the rats in the gallic acid groups were administered different concentrations of gallic acid in a 2-ml gavage daily. All rats were sacrificed on postoperative day 7, and the degree of intra-abdominal adhesion was evaluated by the naked eye. The amount of collagen deposited between the injured peritoneal tissues was assessed by Sirius red staining. Serum levels of interleukin-6 (IL-6), tumor necrosis factor (TNF-α), and transforming growth factor-β (TGF-β) were measured by ELISA. Western blot was used to detect the level of NF-κB phosphorylation in the injured peritoneal or adhesion tissues of the rats. Results Compared with the control group, the scores of intra-abdominal adhesions in the rats treated with larger doses of gallic acid were significantly decreased, and the degree of inflammation and fibrosis was also significantly decreased. Gallic acid significantly reduced IL-6, TNF-α, and TGF-β1 serum levels. NF-κB phosphorylation in the higher gallic acid groups was significantly reduced. Conclusions Gallic acid inhibits the formation of postoperative intra-abdominal adhesions in rats by inhibiting the inflammatory reaction and fibrogenesis. Gallic acid is a promising drug for preventing intra-abdominal adhesions. PMID:29429982

Radiation therapy rather than prior surgery reduces extent of resection during endonasal endoscopic reoperation for craniopharyngioma.

Radiation therapy is often advocated for residual or recurrent craniopharyngioma following surgical resection to prevent local recurrence. However, radiation therapy is not always effective and may render tumors more difficult to remove. If this is the case, patients may benefit more from reoperation if gross total resection can be achieved. Nevertheless, there is little data on the impact of radiation on reoperations for craniopharyngioma. In this study, we sought to analyze whether a history of previous radiation therapy (RT) affected extent of resection in patients with recurrent craniopharyngiomas subsequently treated with reoperation via endoscopic endonasal approach (EEA). The authors reviewed a prospectively acquired database of EEA reoperations of craniopharyngiomas over 13 years at Weill Cornell, NewYork-Presbyterian Hospital. All procedures were performed by the senior author. The operations were separated into two groups based on whether the patient had surgery alone (group A) or surgery and RT (group B) prior to recurrence. A total of 24 patients (16 male, 8 female) who underwent surgery for recurrent craniopharyngioma were identified. The average time to recurrence was 7.64 ± 4.34 months (range 3-16 months) for group A and 16.62 ± 12.1 months (range 6-45 months) for group B (p < 0.05). The average tumor size at recurrence was smaller in group A (1.85 ± 0.72 cm; range 0.5-3.2) than group B (2.59 ± 0.91 cm; range 1.5-4.6; p = 0.00017). Gross total resection (GTR) was achieved in 91% (10/11) of patients in group A and 54% (7/13) of patients in group B (p = 0.047). There was a near significant trend for higher average Karnofsky performance status (KPS) score at last follow-up for group A (83 ± 10.6) compared with group B (70 ± 16.3, p = 0.056). While RT for residual or recurrent craniopharyngioma may delay time to recurrence, ability to achieve GTR with additional surgery is reduced. In the case of

Treatment strategy for ruptured abdominal aortic aneurysms.

Davidovic, L

2014-07-01

Rupture is the most serious and lethal complication of the abdominal aortic aneurysm. Despite all improvements during the past 50 years, ruptured abdominal aortic aneurysms are still associated with very high mortality. Namely, including patients who die before reaching the hospital, the mortality rate due to abdominal aortic aneurysm rupture is 90%. On the other hand, during the last twenty years, the number of abdominal aortic aneurysms significantly increased. One of the reasons is the fact that in majority of countries the general population is older nowadays. Due to this, the number of degenerative AAA is increasing. This is also the case for patients with abdominal aortic aneurysm rupture. Age must not be the reason of a treatment refusal. Optimal therapeutic option ought to be found. The following article is based on literature analysis including current guidelines but also on my Clinics significant experience. Furthermore, this article show cases options for vascular medicine in undeveloped countries that can not apply endovascular procedures at a sufficient level and to a sufficient extent. At this moment the following is evident. Thirty-day-mortality after repair of ruptured abdominal aortic aneurysms is significantly lower in high-volume hospitals. Due to different reasons all ruptured abdominal aortic aneurysms are not suitable for EVAR. Open repair of ruptured abdominal aortic aneurysm should be performed by experienced open vascular surgeons. This could also be said for the treatment of endovascular complications that require open surgical conversion. There is no ideal procedure for the treatment of AAA. Each has its own advantages and disadvantages, its own limits and complications, as well as indications and contraindications. Future reductions in mortality of ruptured abdominal aortic aneurysms will depend on implementation of population-based screening; on strategies to prevent postoperative organ injury and also on new medical technology

Abdominal emergencies during pregnancy.

Bouyou, J; Gaujoux, S; Marcellin, L; Leconte, M; Goffinet, F; Chapron, C; Dousset, B

Abdominal emergencies during pregnancy (excluding obstetrical emergencies) occur in one out of 500-700 pregnancies and may involve gastrointestinal, gynecologic, urologic, vascular and traumatic etiologies; surgery is necessary in 0.2-2% of cases. Since these emergencies are relatively rare, patients should be referred to specialized centers where surgical, obstetrical and neonatal cares are available, particularly because surgical intervention increases the risk of premature labor. Clinical presentations may be atypical and misleading because of pregnancy-associated anatomical and physiologic alterations, which often result in diagnostic uncertainty and therapeutic delay with increased risks of maternal and infant morbidity. The most common abdominal emergencies are acute appendicitis (best treated by laparoscopic appendectomy), acute calculous cholecystitis (best treated by laparoscopic cholecystectomy from the first trimester through the early part of the third trimester) and intestinal obstruction (where medical treatment is the first-line approach, just as in the non-pregnant patient). Acute pancreatitis is rare, usually resulting from trans-ampullary passage of gallstones; it usually resolves with medical treatment but an elevated risk of recurrent episodes justifies laparoscopic cholecystectomy in the 2nd trimester and endoscopic sphincterotomy in the 3rd trimester. The aim of the present work is to review pregnancy-induced anatomical and physiological modifications, to describe the main abdominal emergencies during pregnancy, their specific features and their diagnostic and therapeutic management.

Full Text Available Publications of recent years do not reflect the regional dynamics of hospitalization of patients with acute surgical pathology of the abdominal cavity and anterior abdominal wall. Goal – to determine the volume of hospitalizations and treatment of patients with acute surgical pathology of the abdominal and anterior abdominal wall in the Kuzbass in the dynamics from 1993 to 2016. Materials and methods. A comparative analysis of the volume of treatment of patients with acute appendicitis, acute cholecystitis, acute pancreatitis, intestinal obstruction, perforated ulcer of the stomach and duodenum and strangulated hernia in surgical departments of Kuzbass from 1993 to 2016 to understand the changes occurring in abdominal surgery. Estimated in the comparative aspect for two decades (1993-2002 and 2007-2016 the average annual number of treated. The estimation of indicators in calculation on 100000 population is executed. The statistical processing was carried out using IBM SPSS Statistica computer version 24 and the nonparametric Mann-Whitney test. Result. Statistically significantly decreased the number of patients with acute appendicitis and perforated ulcers of the stomach and duodenum. The average annual hospitalization of patients with acute pancreatitis and strangulated abdominal hernias has significantly increased in the last decade. There are no significant differences in the increase in the total number of patients with acute cholecystitis and acute intestinal obstruction. Conclusions: 1. Over the past decade compared with 1993-2002, the incidence of acute appendicitis per 100000 thousand of the population decreased in the region by 39.9 %, the incidence of perforated gastric ulcer and duodenal ulcer by 30.2 %. 2. At this time, the number of people treated with 100000 people with acute pancreatitis increased by 94.7 %; with acute cholecystitis by 12.4 %; with an acute intestinal obstruction by 9.8 % and with a strangulated

Full Text Available Background If a chronically infected abdominal wound develops, complications such asperitonitis and an abdominal wall defect could occur. This could prolong the patient’s hospitalstay and increase the possibility of re-operation or another infection as well. For this reason,a solution for infection control is necessary. In this study, surgery using a rectus abdominismuscle myofascial splitting flap was performed on an abdominal wall defect.Methods From 2009 to 2012, 5 patients who underwent surgery due to ovarian rupture,cesarean section, or uterine myoma were chosen. In each case, during the first week afteroperation, the wound showed signs of infection. Surgery was chosen because the wounds didnot resolve with dressing. Debridement was performed along the previous operation woundand dissection of the skin was performed to separate the skin and subcutaneous tissue fromthe attenuated rectus muscle and Scarpa’s fascial layers. Once the anterior rectus sheath andmuscle were adequately mobilized, the fascia and muscle flap were advanced medially sothat the skin defect could be covered for reconstruction.Results Upon 3-week follow-up after a rectus abdominis myofascial splitting flap operation,no major complication occurred. In addition, all of the patients showed satisfaction in termsof function and esthetics at 3 to 6 months post-surgery.Conclusions Using a rectus abdominis myofascial splitting flap has many esthetic andfunctional benefits over previous methods of abdominal defect treatment, and notably, itenabled infection control by reconstruction using muscle.

Invasive meningococcal disease (IMD) is recognized as septicemia and/or meningitis. However, early symptoms may vary and are frequently nonspecific. Early abdominal presentations have been increasingly described. We aimed to explore a large cohort of patients with initial abdominal presentations for association with particular meningococcal strains. Confirmed IMD cases in France between 1991-2016 were screened for the presence within the 24 hours before diagnosis of at least one of the following criteria (1) abdominal pain, (2) gastro-enteritis with diarrhea and vomiting, (3) diarrhea only. Whole genome sequencing was performed on all cultured isolates. We identified 105 cases (median age 19 years) of early abdominal presentations with a sharp increase since 2014. Early abdominal pain alone was the most frequent symptom (n=67, 64%), followed by gastro-enteritis (n=26, 25%) and diarrhea alone (n=12, 11%). Twenty patients (20%) had abdominal surgery. A higher case fatality rate (24%) was observed in these cases compared to 10.4% in all IMD in France (p=0.007) with high levels of inflammation markers in the blood. Isolates of group W were significantly more predominant in these cases compared to all IMD. Most of these isolates belonged to clonal complex ST-11 (cc11) of the sublineages of the South American-UK strain. Abdominal presentations are frequently provoked by hyperinvasive isolates of meningococci. Delay in the management of these cases and the virulence of the isolates may explain the high fatality rate. Rapid recognition is a key element to improve their management.

THE ROLE OF LAPAROSCOPY IN BLUNT ABDOMINAL TRAUMA: DIAGNOSTIC, THERAPEUTIC OR BOTH?

Mosai, F

2017-09-01

The use of laparoscopy in blunt abdominal trauma is gaining popularity as a useful diagnostic tool to avoid unnecessary laparotomies where there is diagnostic dilemma. But the feasibility of using laparoscopy for therapeutic intervention in these patients has been debated. Even though recent case reports seem to suggest that these patients can be managed using laparoscopy, the practice is not yet wildly adopted. A retrospective analysis of a prospectively collected data was done. All adult patients who presented with abdominal trauma and were offered laparoscopic surgery at DGMAH from 2012 to 2015 were reviewed. Data was retrieved from our departmental database and analysed using descriptive statistics. A total of 318 patients were reviewed and 35 patients had blunt abdominal trauma and were included in the study. All the patients were offered laparoscopy. The median age was 30, with 91% of our patients being males. The highest injury severity score calculated was 38. At least 77% of the patients were managed using laparoscopy. This includes 43% who had both diagnostic and therapeutic intervention and 34% had only diagnostic laparoscopy. Eight patients were converted to open surgery mainly due to active bleeding and complex injuries. We did not have any non-therapeutic laparotomies, with no documented procedure related morbidity and mortality. The positive outcomes seen from the study suggest that laparoscopy can be safe and feasible in both diagnostic and therapeutic interventions in carefully selected blunt abdominal trauma patients. A conversion to open surgery should not be regarded as a failure but rather as a sign of mature and sound clinical judgement acknowledging the limitations of laparoscopy and/or the surgeon.

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

A rare case of symptomatic mesenteric cysts in a patient with Gorlin-Goltz syndrome, associated with various neoplasms, is presented. The patient, known with Gorlin-Goltz syndrome, consulted with increasingly severe abdominal pain and large abdominal cysts. At surgery, the cysts were excised and the postoperative course was uneventful. In conclusion, this case reminds clinicians to always maintain a wide differential diagnosis when dealing with patients known with Gorlin-Goltz syndrome.

To identify CT findings predictive of surgical management in non-emergency small bowel obstruction (SBO). Contrast-enhanced abdominal CT of 129 patients with non-emergency SBO were evaluated for small bowel luminal diameter, wall thickness, presence of the small bowel faeces sign (intraluminal particulate matter in a dilated small bowel) and length, transition point, submucosal oedema, mesenteric stranding, ascites and degree of obstruction (low grade partial, high grade partial and complete obstruction). Medical records were reviewed for age, gender, management and history of abdominal surgery, abdominal malignancy, or SBO. Statistical analyses were performed with Stata Release 9.2. Degree of obstruction was the only predictor of need for surgery. Whereas 18.0% of patients with low-grade partial obstruction (n = 50) underwent surgery, 32.5% of patients with high-grade partial obstruction (n = 77) and 100% of patients with complete obstruction (n = 2) required surgery (P = 0.004). The small bowel faeces sign was inversely predictive of surgery (P = 0.018). In non-emergency SBO patients with contrast-enhanced CT imaging, grade of obstruction predicts surgery, while the small bowel faeces sign inversely predicts need for surgery. (orig.)
