BACKGROUND AND PURPOSE Electrical stimulation of the vagus nerve reduces intestinal inflammation following mechanical handling, thereby shortening post-operative ileus in mice. Previous studies in a sepsis model showed that this cholinergic anti-inflammatory pathway can be activated pharmacologically by central administration of semapimod, an inhibitor of p38 mitogen-activated protein kinase. We therefore evaluated the effect of intracerebroventricular (i.c.v.) semapimod on intestinal inflammation and post-operative ileus in mice. EXPERIMENTAL APPROACH Mice underwent a laparotomy or intestinal manipulation 1 h after i.c.v. pre-treatment with semapimod (1 µg·kg−1) or saline. Drugs were administered through a cannula placed in the left lateral ventricle 1 week prior to experimentation. Twenty-four hours after surgery, gastric emptying was measured using scintigraphy, and the degree of intestinal inflammation was assessed. Finally, activation of brain regions was assessed using quantitative immunohistochemistry for c-fos. KEY RESULTS Intestinal manipulation induced inflammation of the manipulated intestine and significantly delayed gastric emptying, 24 h after surgery in saline-treated animals. Semapimod significantly reduced this inflammation and improved gastric emptying. Vagotomy enhanced the inflammatory response induced by intestinal manipulation and abolished the anti-inflammatory effect of semapimod. Semapimod but not saline induced a significant increase in c-fos expression in the paraventricular nucleus, the nucleus of the solitary tract and the dorsal motor nucleus of the vagus nerve. CONCLUSIONS AND IMPLICATIONS Our findings show that i.c.v. semapimod reduces manipulation-induced intestinal inflammation and prevented post-operative ileus. This anti-inflammatory effect depends on central activation of the vagus nerve. PMID:21371006

There is no consensual definition of postoperative ileus (POI), which leads to a lack of reproducibility. The aims of this study were (i) to propose and evaluate a classification of postoperative ileus based on its consequences and (ii) to assess the reproducibility of the classification. A national global survey was carried out according to the DELPHI method in order to create a classification of primary POI. The classification was subsequently tested on a cohort of patients who underwent colorectal surgery. Finally, a reproducibility test was performed in five teaching hospitals with junior and senior surgeons. A five-stage classification was proposed: grade A (least) to grade E (worst). For better differentiation, subcategories (D1/D2) were included. Overall, 173 patients were included who underwent colorectal surgery. Forty of them experienced primary postoperative ileus (23.1%). Grade A occurred in 10 cases, grade B in 10 cases, grade C in 14 cases, grade D1 in 2 cases, and grade D2 in 2 cases. POI-related death (grade E) occurred in 2 cases. Patients with grade A POI recovered their gastrointestinal function significantly faster than those with higher grades (p = 0.01), and were more likely to undergo laparoscopic surgery (p = 0.04). The Intraclass Correlation Coefficient (ICC) was 0.83 in the overall population, and 0.83 and 0.82 respectively in the junior and senior surgeon populations. This classification is easy to both use and reproduce. It will improve the reproducibility, evaluation, and assessment of POI. These preliminary results should be confirmed in a multi-centric international study.

Postoperative ileus is one of the main complications in the postoperative period. New measures appeared with the introduction of «fast-track surgery» to accelerate recovery: coffee, chewing gum and gastrograffin. We performed a summary of current evidence, reviewing articles from MEDLINE, Cochrane Database of Systematic Reviews, ISI Web of Science, and SCOPUS databases. Employed search terms were «postoperative ileus» AND («definition» OR «epidemiology» OR «risk factors» OR «Management»). We selected 44 articles: 9 systematic reviews 11 narrative reviews, 13 randomized clinical trials, 6 observational studies, and the remaining 5 scientific letters, assumptions, etc. There is little literature about this topic, studies are heterogeneous, with disparity in the results. In addition, they only focus on colorectal and gynecological surgery. New high-quality studies are needed, preferably randomized clinical trials, in order to clarify the usefulness of these measures.

Post-operative ileus (POI) is a serious condition which any horse undergoing abdominal surgery is at risk of developing, leading to increased hospitalisation time and resulting costs. Advances in the understanding of the development of equine POI are mainly based on human and rodent literature, where manipulation-induced inflammation has been identified as a trigger, with activation of resident muscularis externa macrophages playing a crucial role in the pathophysiology. Despite many pharmacological trials in all species, there is no single completely successful treatment for POI, highlighting that the condition is multifactorial in cause and requires a multimodal approach to minimise its incidence. © 2017 EVJ Ltd.

Inflammatory reactions are par- tially responsible for postoperative ileus (POI). Serum C-reactive protein (CRP) is an acknowledged marker of inflammation. In this study the CRP response with respect to POI in elective colorectal surgery was exam- ined to define the role of serum CRP as an early predic- tor of POI. Three hundred eighty-three patients who underwent elective colorectal resection were identified for inclusion in this study. We defined early POI as that occurring within 30 days following the surgery. Thirty-five patients with POI were com- pared to a subgroup of 348 patients with an unevent- ful postoperative course, and the correlation between postoperative serum CRP levels and POI in colorectal surgery was investigated. In the univariate analysis, length of operation, surgical blood loss, and serum CRP were factors significantly associated with POI following colorectal surgery; however, these fac- tors lost their significance on multivariate analysis. Our results suggest that an increase in CRP levels alone is not a predictor for POI following surgery for colorectal surgery. Although inflammatory responses are known to contribute to the ileus, ad- ditional study is required to identify risk factors that would be more useful for prediction of POI.

Small intestinal function returns first after surgery, and then the function of the stomach returns to normal after postoperative ileus (POI). The aim of this study was to investigate inflammatory responses in the muscle coat of stomach and small intestine in guinea pig POI model. The distance of charcoal migration from pylorus to the distal intestine was measured. Hematoxylin and eosin (H&E) and immunohistochemical stain for calprotectin were done from the histologic sections of stomach, jejunum and ileum obtained at 3 and 6 hour after operation. Data were compared between sham operation and POI groups. The distance of charcoal migration was significantly reduced in the 3 and 6 hour POI groups compared with sham operated groups (p<0.05). On H&E staining, the degree of inflammation was significantly higher in the stomach of 3 hour POI groups compared with jejunum and ileum of POI groups or sham operated groups (p<0.05). Calprotectin positive cells were significantly increased in the muscle coat of stomach of 3 hour POI groups compared with jejunum and ileum of POI groups or sham operated groups (p<0.05). There was strong association between the degree of inflammation and calprotectin positive cells in stomach. Postoperative ileus induced by cecal manipulation significantly increased the degree of inflammation and calprotectin positive cells in the muscle coat of stomach as a remote organ. The relevance of degree of inflammation and the recovery time of ileus should be pursued in the future research.

Management of prolonged post-operative ileus: evidence-based recommendations.

Prolonged post-operative ileus (PPOI) occurs in up to 25% of patients following major elective abdominal surgery. It is associated with a higher risk of developing post-operative complications, prolongs hospital stay and confers a significant financial load on health-care institutions. Literature outlining best-practice management strategies for PPOI is nebulous. The aim of this text was to review the literature and provide concise evidence-based recommendations for its management. A literature search through the Ovid MEDLINE, EMBASE, Google Scholar and Cochrane databases was performed from inception to July 2012 using a combination of keywords and MeSH terms. Review of the literature was followed by synthesis of concise recommendations for management accompanied by Strength of Recommendation Taxonomy (either A, B or C). Recommendations for management include regular evaluation and correction of electrolytes (B); review of analgesic prescription with weaning of narcotics and substitution with regular paracetamol, regular non-steroidal anti-inflammatory drugs if not contraindicated, and regular or as-required Tramadol (A); nasogastric decompression for those with nausea or vomiting as prominent features (C); isotonic dextrose-saline crystalloid maintenance fluids administered within a restrictive regimen (B); balanced isotonic crystalloid replacement fluids containing supplemental potassium, in equivalent volume to losses (C); regular ambulation (C); parenteral nutrition if unable to tolerate an adequate oral intake for more than 7 days post-operatively (A) and exclusion of precipitating pathology or alternate diagnoses if clinically suspected (C). Recommendations have a variable and frequently inconsistent evidence base. Further research is required to validate many of the outlined recommendations and to investigate novel interventions that may be used to shorten duration of PPOI. © 2013 The Authors.

Postoperative ileus (POI), an interruption of coordinated bowel motility after operation, is exacerbated by opioids used to manage pain. Alvimopan, a peripherally acting mu-opioid receptor antagonist, accelerated gastrointestinal (GI) recovery after bowel resection in randomized, double-blind, placebo-controlled, multicenter phase III POI trials. The effect of alvimopan on POI-related morbidity for patients who underwent bowel resection was evaluated in a post-hoc analysis. Incidence of POI-related postoperative morbidity (postoperative nasogastric tube insertion or POI-related prolonged hospital stay or readmission) was analyzed in four North American trials for placebo or alvimopan 12 mg administered 30 minutes or more preoperatively and twice daily postoperatively until hospital discharge (7 or fewer postoperative days). GI-related adverse events and opioid consumption were summarized for each treatment. Estimations of odds ratios of alvimopan to placebo and number needed to treat (NNT) to prevent one patient from experiencing an event of POI-related morbidity were derived from the analysis. Patients receiving alvimopan 12 mg were less likely to experience POI-related morbidity than patients receiving placebo (odds ratio = 0.44, p < 0.001). Fewer patients receiving alvimopan (alvimopan, 7.6%; placebo, 15.8%; NNT = 12) experienced POI-related morbidity. There was a lower incidence of postoperative nasogastric tube insertion, and other GI-related adverse events on postoperative days 3 to 6 in the alvimopan group than the placebo group. Opioid consumption was comparable between groups. Alvimopan 12 mg was associated with reduced POI-related morbidity compared with placebo, without compromising opioid-based analgesia in patients undergoing bowel resection. Relatively low NNTs are clinically meaningful and reinforce the potential benefits of alvimopan for the patient and health care system.

Intravenous opioids represent a major component in the pathophysiology of postoperative ileus (POI). However, the most appropriate measure and threshold to quantify the association between opioid dose (eg, average daily, cumulative, maximum daily) and POI remains unknown. To evaluate the relationship between opioid dose, POI, and length of stay (LOS) and identify the opioid measure that was most strongly associated with POI. Consecutive patients admitted to a community teaching hospital who underwent elective colorectal surgery by any technique with an enhanced-recovery protocol postoperatively were retrospectively identified. Patients were excluded if they received epidural analgesia, developed a major intraabdominal complication or medical complication, or had a prolonged workup prior to surgery. Intravenous opioid doses were quantified and converted to hydromorphone equivalents. Classification and regression tree (CART) analysis was used to determine the dosing threshold for the opioid measure most associated with POI and define high versus low use of opioids. Risk factors for POI and prolonged LOS were determined through multivariate analysis. The incidence of POI in 279 patients was 8.6%. CART analysis identified a maximum daily intravenous hydromorphone dose of 2 mg or more as the opioid measure most associated with POI. Multivariate analysis revealed maximum daily hydromorphone dose of 2 mg or more (p = 0.034), open surgical technique (p = 0.045), and days of intravenous narcotic therapy (p = 0.003) as significant risk factors for POI. Variables associated with increased LOS were POI (p < 0.001), maximum daily hydromorphone dose of 2 mg or more (p < 0.001), and age (p = 0.005); laparoscopy (p < 0.001) was associated with a decreased LOS. Intravenous opioid therapy is significantly associated with POI and prolonged LOS, particularly when the maximum hydromorphone dose per day exceeds 2 mg. Clinicians should consider alternative, nonopioid-based pain

Paralytic postoperative ileus (POI) is associated with increased morbidity and mortality after abdominal surgery. Despite increased awareness and implementation of various measures, POI remains a problem, perhaps moreso for those patients undergoing extensive oncological surgical treatment. The aim of this study was to describe the extent of POI after advanced cancer surgery in the era of contemporary treatment modalities of POI. A retrospective analysis of all patients who underwent either abdominoperineal excision with transpelvic vertical rectus abdominal musculocutaneous (VRAM)-flap after anal cancer or pelvic exenteration at single institution from January 2012 to November 2013 was carried out. Patients were identified from operative codes, and data were retrieved from patient records. Eighty-nine patients were included in the study, 21 abdominoperineal excision and 68 pelvic exenteration procedures. Median nasogastric tube duration was 4 days (range: 0-44). Median time to first flatus was 1 day (range 0-15). Median time to defecation was 3 days (range 0-16 days). Twenty-three patients (28%) experienced prolonged ileus. There was a significant longer time to first defecation for patients who received a VRAM flap (P = 0.046). There was also a significant association between longer operative times and first flatus (P = 0.007). This retrospective study reveals that POI remains as a significant clinical problem in patients undergoing advanced pelvic cancer surgery, despite the increased awareness and implementation of enhanced recovery protocols. New regimens for better prophylaxis are needed, and further research on POI treatment is important. Copyright © 2017 Elsevier Inc. All rights reserved.

Postoperative ileus (POI) is an important factor prolonging the length of hospital stay following colorectal surgery. We retrospectively explored whether there is a clinically relevant association between intraoperative hypothermia and POI in patients who underwent laparoscopic colorectal surgery for malignancy within the setting of an enhanced recovery after surgery (ERAS) program between April 2016 and January 2017 at our institution. In total, 637 patients were analyzed, of whom 122 (19.2%) developed clinically and radiologically diagnosed POI. Overall, 530 (83.2%) patients experienced intraoperative hypothermia. Although the mean lowest core temperature was lower in patients with POI than those without POI (35.3 ± 0.5°C vs. 35.5 ± 0.5°C, P = 0.004), the independence of intraoperative hypothermia was not confirmed based on multivariate logistic regression analysis. In addition to three variables (high age-adjusted Charlson comorbidity index score, long duration of surgery, high maximum pain score during the first 3 days postoperatively), cumulative dose of rescue opioids used during the first 3 days postoperatively was identified as an independent risk factor of POI (odds ratio = 1.027 for each 1-morphine equivalent [mg] increase, 95% confidence interval = 1.014-1.040, P <0.001). Patients with hypothermia showed significant delays in both progression to a soft diet and discharge from hospital. In conclusion, intraoperative hypothermia was not independently associated with POI within an ERAS pathway, in which items other than thermal measures might offset its negative impact on POI. However, as it was associated with delayed discharge from the hospital, intraoperative maintenance of normothermia is still needed.

Postoperative ileus is a significant clinical challenge lacking effective management strategies. Ghrelin-receptor stimulation has promotility effects in the upper and lower gastrointestinal tract. This proof-of-concept, phase 2, randomized study evaluated the safety and efficacy of the ghrelin-receptor agonist ipamorelin in the treatment of postoperative ileus following abdominal surgery (ClinicalTrials.gov NCT00672074). The design was a multicenter, double-blind, placebo-controlled, clinical trial. The settings include hospital inpatients. The patients were adults undergoing small and large bowel resection by open or laparoscopic surgery. The intervention was intravenous infusions of 0.03-mg/kg ipamorelin vs placebo twice daily, on postoperative day 1 to 7 or hospital discharge. Safety was assessed by monitoring adverse events and laboratory tests. The key efficacy endpoint was time from first dose of study drug to tolerance of a standardized solid meal. One hundred seventeen patients were enrolled, of whom 114 patients composed the safety and modified intent-to-treat populations. Demographic and disease characteristics were balanced between groups. Overall incidence of any treatment-emergent adverse events was 87.5 % in the ipamorelin group and 94.8 % in placebo group. Median time to first tolerated meal was 25.3 and 32.6 h in the ipamorelin and placebo groups, respectively (p = 0.15). This proof of concept study was small and enrolled patients with a broad range of underlying conditions. Ipamorelin 0.03-mg/kg twice daily for up to 7 days was well tolerated. There were no significant differences between ipamorelin and placebo in the key and secondary efficacy analyses.

Postoperative ileus (POI) is characterized by impaired propulsive function of the gastrointestinal tract after surgery. Although inflammation is considered to be an important pathogenesis of POI, significant data are lacking. We aim to correlate the recovery time of postoperative dysmotility with that of inflammation and mucosal permeability. An experimental POI model of guinea pig was used. Contractile activity of the circular muscle of the stomach, jejunum, ileum, and proximal colon was measured through a tissue bath study. Inflammatory cells were counted, and the expression of calprotectin and tryptase were analyzed. The expression of protease-activated receptor 2 (PAR-2), claudin-1, and claudin-2 were analyzed with immunofluorescence. The small bowel and colon showed decreased contractile amplitude in the POI groups compared to control. In contrast to the colon, the contractile amplitude of the small bowel significantly recovered in the POI group at 6 hours after the operation compared to the control group. Inflammation was highly significant in the POI groups compared to the control and sham groups, especially in the colon. Immunofluorescence showed increased PAR-2 expression in the POI groups compared to sham. The decreased claudin-1 expression and increased claudin-2 expression may suggest increased mucosal permeability of the small bowel and colon in the POI groups. Increased inflammation and mucosal permeability may play an important role in the differential recovery stages in POI. These data may provide further insights into the pathophysiology and potential new therapeutic prospects of POI.

Postoperative ileus (POI) is a common consequence of abdominal surgery that increases the risk of postoperative complications and morbidity. We investigated the cellular mechanisms and immune responses involved in the pathogenesis of POI. We studied a mouse model of POI in which intestinal manipulation leads to inflammation of the muscularis externa and disrupts motility. We used C57BL/6 (control) mice as well as mice deficient in Toll-like receptors (TLRs) and cytokine signaling components (TLR-2(-/-), TLR-4(-/-), TLR-2/4(-/-), MyD88(-/-), MyD88/TLR adaptor molecule 1(-/-), interleukin-1 receptor [IL-1R1](-/-), and interleukin (IL)-18(-/-) mice). Bone marrow transplantation experiments were performed to determine which cytokine receptors and cell types are involved in the pathogenesis of POI. Development of POI did not require TLRs 2, 4, or 9 or MyD88/TLR adaptor molecule 2 but did require MyD88, indicating a role for IL-1R1. IL-1R1(-/-) mice did not develop POI; however, mice deficient in IL-18, which also signals via MyD88, developed POI. Mice given injections of an IL-1 receptor antagonist (anakinra) or antibodies to deplete IL-1α and IL-1β before intestinal manipulation were protected from POI. Induction of POI activated the inflammasome in muscularis externa tissues of C57BL6 mice, and IL-1α and IL-1β were released in ex vivo organ bath cultures. In bone marrow transplantation experiments, the development of POI required activation of IL-1 receptor in nonhematopoietic cells. IL-1R1 was expressed by enteric glial cells in the myenteric plexus layer, and cultured primary enteric glia cells expressed IL-6 and the chemokine monocyte chemotactic protein 1 in response to IL-1β stimulation. Immunohistochemical analysis of human small bowel tissue samples confirmed expression of IL-1R1 in the ganglia of the myenteric plexus. IL-1 signaling, via IL-1R1 and MyD88, is required for development of POI after intestinal manipulation in mice. Agents that interfere with

Intestinal manipulation (IM) during abdominal surgery results in intestinal inflammation leading to hypomotility or ileus. Mast cell activation is thought to play a crucial role in the pathophysiology of postoperative ileus (POI). However, this conclusion was mainly drawn using mast cell-deficient mouse models with abnormal Kit signaling. These mice also lack interstitial cells of Cajal (ICC) resulting in aberrant gastrointestinal motility even prior to surgery, compromising their use as model to study POI. To avoid these experimental weaknesses we took advantage of a newly developed knock-in mouse model, Cpa3(Cre/+) , devoid of mast cells but with intact Kit signaling. The role of mast cells in the development of POI and intestinal inflammation was evaluated assessing gastrointestinal transit and muscularis externa inflammation after IM in two strains of mice lacking mast cells, i.e. Kit(W-sh/W-sh) and Cpa3(Cre/+) mice, and by use of the mast cell stabilizer cromolyn. Kit(W-sh/W-sh) mice lack ICC networks and already revealed significantly delayed gastrointestinal transit even before surgery. IM did not further delay intestinal transit, but induced infiltration of myeloperoxidase positive cells, expression of inflammatory cytokines and recruitment of monocytes and neutrophils into the muscularis externa. On the contrary, Cpa3(Cre/+) mice have a normal network of ICC and normal gastrointestinal. Surprisingly, IM in Cpa3(Cre/+) mice caused delay in gut motility and intestinal inflammation as in wild type littermates mice (Cpa3(+/+) ). Furthermore, treatment with the mast cell inhibitor cromolyn resulted in an inhibition of mast cells without preventing POI. Here, we confirm that IM induced mast cell degranulation. However, our data demonstrate that mast cells are not required for the pathogenesis of POI in mice. Although there might be species differences between mouse and human, our results argue against mast cell inhibitors as a therapeutic approach to shorten POI.

Aim To explore the effects of abdominal surgery and interleukin-1 signaling on antimicrobial defense in a model of postoperative ileus. Methods C57BL/6 and Interleukin-1 receptor type I (IL-1R1) deficient mice underwent intestinal manipulation to induce POI. Expression of mucosal IL-1α, IL-1β and IL-1R1 and several antimicrobial peptides and enzymes were measured by quantitative PCR or ELISA, western blotting or immunohistochemistry. Bacterial overgrowth was determined by fluorescent in-situ hybridization and counting of jejunal luminal bacteria. Translocation of aerobic and anaerobic bacteria into the intestinal wall, mesenteric lymph nodes, liver and spleen was determined by counting bacterial colonies on agar plates 48h after plating of tissue homogenates. Antimicrobial activity against E. coli and B. vulgatus was analyzed in total and cationic fractions of small bowel mucosal tissue homogenates by a flow cytometry-based bacterial depolarization assay. Results Jejunal bacterial overgrowth was detected 24h after surgery. At the same time point, but not in the early phase 3h after surgery, bacterial translocation into the liver and mesenteric lymph nodes was observed. Increased antimicrobial activity against E. coli was induced within early phase of POI. Basal antimicrobial peptide and enzyme gene expression was higher in the ileal compared to the jejunal mucosa. The expression of lysozyme 1, cryptdin 1, cryptdin 4 and mucin 2 were reduced 24h after surgery in the ileal mucosa and mucin 2 was also reduced in the jejunum. Postoperative IL-1α and IL-1β were increased in the postoperative mucosa. Deficiency of IL-1R1 affected the expression of antimicrobial peptides during homeostasis and POI. Conclusion Small bowel antimicrobial capacity is disturbed during POI which is accompanied by bacterial overgrowth and translocation. IL-1R1 is partially involved in the gene expression of mucosal antimicrobial peptides. Altered small bowel antimicrobial activity may

Although postoperative ileus (POI) is considered multifactorial, intestinal inflammation resulting from manipulation-induced mast cell activation is recognized as an important pathophysiological mechanism. Therefore, mast cell stabilization may represent a new therapeutic approach to shortening POI. The aim of this paper was to study the effect of ketotifen, a mast cell stabilizer, on postoperative gastrointestinal transit in patients who underwent abdominal surgery. In this pilot study, 60 patients undergoing major abdominal surgery for gynecological malignancy with standardized anesthesia were randomized to treatment with ketotifen (4 or 12 mg) or placebo. Patients were treated for 6 days, starting 3 days before surgery. Gastric emptying of liquids, selected as a primary outcome parameter, was measured 24 h after surgery using scintigraphy. Secondary end points were (scintigraphically assessed) colonic transit, represented as geometrical center of activity (segment 1(cecum) to 7(stool)) and clinical parameters. Gastric retention 1 h after liquid intake was significantly reduced by 12 mg (median 3% (1-7), P=0.01), but not by 4 mg ketotifen (18% (3-45), P=0.6) compared with placebo (16% (5-75)). Twenty-four hour colonic transit in placebo was 0.8 (0.0-1.1) vs. 1.2 (0.2-1.4) colon segments in the 12 mg ketotifen group (P=0.07). Abdominal cramps were significantly relieved in patients treated with 12 mg ketotifen, whereas other clinical parameters were not affected. Ketotifen significantly improves gastric emptying after abdominal surgery and warrants further exploration of mast cell stabilizers as putative therapy for POI.

Introduction Intestinal manipulation (IM) during abdominal surgery results in intestinal inflammation leading to hypomotility or ileus. Mast cell activation is thought to play a crucial role in the pathophysiology of postoperative ileus (POI). However, this conclusion was mainly drawn using mast cell-deficient mouse models with abnormal Kit signaling. These mice also lack interstitial cells of Cajal (ICC) resulting in aberrant gastrointestinal motility even prior to surgery, compromising their use as model to study POI. To avoid these experimental weaknesses we took advantage of a newly developed knock-in mouse model, Cpa3Cre/+, devoid of mast cells but with intact Kit signaling. Design The role of mast cells in the development of POI and intestinal inflammation was evaluated assessing gastrointestinal transit and muscularis externa inflammation after IM in two strains of mice lacking mast cells, i.e. KitW-sh/W-sh and Cpa3Cre/+ mice, and by use of the mast cell stabilizer cromolyn. Results KitW-sh/W-sh mice lack ICC networks and already revealed significantly delayed gastrointestinal transit even before surgery. IM did not further delay intestinal transit, but induced infiltration of myeloperoxidase positive cells, expression of inflammatory cytokines and recruitment of monocytes and neutrophils into the muscularis externa. On the contrary, Cpa3Cre/+ mice have a normal network of ICC and normal gastrointestinal. Surprisingly, IM in Cpa3Cre/+ mice caused delay in gut motility and intestinal inflammation as in wild type littermates mice (Cpa3+/+). Furthermore, treatment with the mast cell inhibitor cromolyn resulted in an inhibition of mast cells without preventing POI. Conclusions Here, we confirm that IM induced mast cell degranulation. However, our data demonstrate that mast cells are not required for the pathogenesis of POI in mice. Although there might be species differences between mouse and human, our results argue against mast cell inhibitors as a therapeutic

To investigate the therapeutic value of Gastrografin in shortening duration of prolonged postoperative ileus (PPOI) after elective colorectal surgery. Gut wall edema is central to the pathogenesis of PPOI. Hyperosmotic, orally administered, water-soluble contrast media such as Gastrografin are theoretically capable of mitigating this edema. A double-blinded, placebo-controlled, randomized trial was conducted. Participants were allocated to receive 100 mL of Gastrografin (Exposure Group) or flavored distilled water (Control Group) administered enterally. Other aspects of management were standardized. Resolution of PPOI was assessed 12-hourly. Eighty patients were randomized equally, with 5 in the Exposure Group and 4 in the Control Group excluded from analysis. Participants were evenly matched at baseline. Mean duration of PPOI did not differ between Exposure and Control Groups (83.7 vs 101.3 hours; P = 0.191). When considering individual markers of PPOI resolution, Gastrografin did not affect time to resolution of nausea and vomiting (64.5 vs 74.3 hours; P = 0.404) or consumption of oral diet (75.8 vs 90.0 hours; P = 0.297). However, it accelerated time to flatus or stool (18.9 vs 32.7 hours; P = 0.047) and time to resolution of abdominal distension (52.8 vs 77.7 hours; P = 0.013). There were no significant differences between groups in nasogastric output; analgesia, antiemetic, or fluid requirement; complications; or length of stay. Gastrografin is not clinically useful in shortening an episode of PPOI characterized by upper and lower gastrointestinal symptoms. It may however be of therapeutic benefit in the subset of PPOI patients who display lower gastrointestinal symptoms exclusively after surgery.

Postoperative ileus (POI) is a transient bowel dysmotility that occurs following many types of operations and is one of the most common complications of gastrointestinal surgery. We hypothesized that enteral supplementation of glutamine after abdominal surgery would restore fuel to the small intestine, suppress oxidative stress, and lead to improvement in POI. Twelve dogs underwent distal gastrectomy and were each randomly assigned to one of two groups based on postoperative treatment: the water injection (control) group and the glutamine injection group. Water (40 ml) or L(+)-glutamine (1 g/40 ml water) was injected into the residual stomach through the gastric tube every 12 h after surgery for 7 days. Changes in the plasma and intestinal intracellular concentration of glutamine and in gastrointestinal motility were measured. The plasma and intracellular glutamine levels decreased after the operation in both groups, although the decreased intracellular glutamine levels were not significantly different than preoperative levels. The glutamine group showed a significantly smaller decrease of the plasma glutamine level compared with the control group (P < 0.05). All the dogs showed gastrointestinal dysmotility after the operation. The mean length of time between the operation and the appearance of interdigestive migrating contractions in the glutamine group was significantly shorter than in the control group (22.4 +/- 3.1 h versus 37.8 +/- 4.0 h, respectively; P < 0.05). In conclusion, glutamine could act as a motility-recovery agent after abdominal surgery and thereby decrease the duration of POI.

Ghrelin and ghrelin mimetics stimulate appetite and enhance gastric motility. The present study investigates whether ipamorelin, a selective growth hormone secretagogue and agonist of the ghrelin receptor, would accelerate gastrointestinal transit and ameliorate the symptoms in a rodent model of postoperative ileus (POI). Fasted male rats were subjected to laparotomy and intestinal manipulation. At the end of surgery, a dye marker was infused in the proximal colon to evaluate postsurgical colonic transit time, which was the time to the first bowel movement. In addition, fecal pellet output, food intake, and body weight were monitored regularly for 48 h. Ipamorelin (0.01-1 mg/kg), growth hormone-releasing peptide (GHRP)-6 (20 microg/kg), or vehicle (saline) were administered via intravenous bolus infusion after a single dosing or a 2-day repetitive dosing regimen (four doses a day at 3-h intervals). Compared with the vehicle, a single dose of ipamorelin (1 mg/kg) or GHRP-6 (20 microg/kg) decreased the time to the first bowel movement but had no effect on cumulative fecal output, food intake, or body weight gain measured 48 h after the surgery. In contrast, repetitive dosing of ipamorelin (0.1 or 1 mg/kg) significantly increased the cumulative fecal pellet output, food intake, and body weight gain. The results suggest that postsurgical intravenous infusions of ipamorelin may ameliorate the symptoms in patients with POI.

Postoperative ileus (POI) is an iatrogenic complication of abdominal surgery, mediated by a severe inflammation of the muscularis externa (ME). Previously, we demonstrated that intravenous application of the tetravalent guanylhydrazone semapimod (CNI-1493) prevents POI, but the underlying mode of action could not definitively be confirmed. Herein, we investigated the effect of a novel orally active salt of semapimod (CPSI-2364) on POI in rodents and distinguished between its inhibitory peripheral and stimulatory central nervous effects on anti-inflammatory vagus nerve signaling. Distribution of radiolabeled orally administered CPSI-2364 was analyzed by whole body autoradiography and liquid scintillation counting. POI was induced by intestinal manipulation with or without preoperative vagotomy. CPSI-2364 was administered preoperatively via gavage in a dose- and time-dependent manner. ME specimens were assessed for p38-MAP kinase activity by immunoblotting, neutrophil extravasation, and nitric oxide production. Furthermore, in vivo gastrointestinal (GIT) and colonic transit were measured. Autoradiography demonstrated a near-exclusive detection of CPSI-2364 within the gastrointestinal wall and contents. Preoperative CPSI-2364 application significantly reduced postoperative neutrophil counts, nitric oxide release, GIT deceleration, and delay of colonic transit time, while intraoperatively administered CPSI-2364 failed to improve POI. CPSI-2364 also prevents postoperative neutrophil increase and GIT deceleration in vagotomized mice. Orally administered CPSI-2364 shows a near-exclusive dispersal in the gastrointestinal tract and effectively reduces POI independently of central vagus nerve stimulation. Its efficacy after single oral dosage affirms CPSI-2364 treatment as a promising strategy for prophylaxis of POI.

Gastrografin has been suggested as a rescue therapy for prolonged post-operative ileus (PPOI) but trial data has been inconclusive. This study aimed to determine the benefit of gastrografin use in patients with PPOI by pooling the results of two recent randomized controlled trials assessing the efficacy of gastrografin compared to placebo given at time of PPOI diagnosis. Anonymized, individual patient data from patients undergoing elective bowel resection for any indication were included, stoma closure was excluded. The primary outcome was duration of PPOI. Secondary outcomes were time to tolerate oral diet, passage of flatus/stool, requirement and duration of nasogastric tube, length of post-operative stay and rate of post-operative complications. Individual patient data were pooled for analysis (53 gastrografin, 55 placebo). Gastrografin trended towards a reduction in PPOI duration compared to placebo, respectively, median 96 h (interquartile range, IQR, 78 h) versus median 120 h (IQR, 84 h), however, this result was non-significant (P = 0.11). In addition, no significant difference was detected between the two groups for time to passage of flatus/stool (P = 0.36) and overall length of stay (P = 0.35). Gastrografin conferred a significantly faster time to tolerate an oral diet compared to placebo (median 84 h versus median 107 h, P = 0.04). There was no difference in post-operative complications between the two interventions (P > 0.05). Gastrografin did not significantly reduce PPOI duration or length of stay after abdominal surgery, but did reduce time to tolerate a solid diet. Further studies are required to clarify the role of gastrografin in PPOI. © 2018 Royal Australasian College of Surgeons.

To conduct a systematic review and Meta-analysis of the effectiveness of acupuncture and common acupoint selection for postoperative ileus (POI). Randomized controlled trials (RCTs) comparing acupuncture and non-acupuncture treatment were identified from the databases PubMed, Cochrane, EBSCO (Academic Source Premier and MEDLINE), Ovid (including Evidence-Based Medicine Reviews), China National Knowledge Infrastructure, and Wanfang Data. The data from eligible studies were extracted and a Meta-analysis performed using a fixed-effects model. Results were expressed as relative risk (RR) for dichotomous data, and 95% CI (confidence intervals) were calculated. Each trial was evaluated using the CONSORT (Consolidated Standards of Reporting Trials) and STRICTA (STandards for Reporting Interventions in Controlled Trials of Acupuncture) guideline . The quality of the study was assessed using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. Of the 69 studies screened, eight RCTs were included for review. Among these, four RCTs (with a total of 123 patients in the intervention groups and 124 patients in the control groups) met the criteria for Meta-analysis. The Meta-analysis results indicated that acupuncture combined with usual care showed a significantly higher total effective rate than the control condition (usual care) (RR 1.09, 95% CI 1.01, 1.18; P = 0.02). Zusanli (ST 36) and Shangjuxu (ST 37) were the most common acupoints selected. However, the quality of the studies was generally low, as they did not emphasize the use of blinding. The results suggested that acupuncture might be effective in improving POI; however, a definite conclusion could not be drawn because of the low quality of trials. Further large-scale, high-quality randomized clinical trials are needed to validate these findings and to develop a standardized method of treatment. We hope that the present results will lead to improved research, resulting in better

Gallstone ileus is a rare but potentially serious complication of cholelithiasis. It is usually preceded by history of biliary symptoms. It usually occurs as a result of a large gallstone creating and passing through a cholecysto-enteric fistula. Most of the time, the stone will pass the GI tract without any problems, but large enough stones can cause obstruction. The two most common locations of impaction are the terminal ileum and the ileocaecal valve because of the anatomical small diameter and less active peristalsis. We present an unusual case of small bowel obstruction secondary to gallstone ileus 24 years after an open cholecystectomy.

Accelerated recovery programs are clinical pathways which outline the stages, and streamline the means, and techniques aiming toward the desired end a rapid return of the patient to his pre-operative physical and psychological status. Recovery from colo-rectal surgery may be slowed by the patient's general health, surgical stress, post-surgical pain, and post-operative ileus. Both surgeons and anesthesiologists participate throughout the peri-operative period in a clinical pathway aimed at minimizing these delaying factors. Key elements of this pathway include avoidance of pre-operative colonic cleansing, early enteral feeding, and effective post-operative pain management permitting early ambulation (usually via thoracic epidural anesthesia). Pre-operative information and motivation of the patient is also a key to the success of this accelerated recovery program. Studies of such programs have shown decreased duration of post-operative ileus and hospital stay without an increase in complications or re-admissions. The elements of the clinical pathway must be regularly re-evaluated and updated according to local experience and published data.

Gallstone ileus represents 4% of the causes of bowel obstruction in the general population, but increases to 25% in patients above the age of 65 years. Gallstone ileus does not present with unique symptoms, making diagnosis difficult. Its management is surgical, but there is no consensus as to which of the different surgical techniques is the procedure of choice. At present, there is no recent review of this pathology. To conduct an up-to-date review of this disease. Articles published within the time frame of 2000 to 2014 were found utilizing the PUBMED, EMBASE, and Cochrane Library search engines with the terms "gallstone ileus" plus "review" and the following filters: "review", "full text", and "humans". The results of this review showed that gallstone ileus etiology was due to intestinal obstruction from a gallstone that migrated into the intestinal lumen through a bilioenteric fistula. The presence of 2 of the 3 Rigler's triad signs was considered diagnostic. Abdominal tomography was the imaging study of choice for gallstone ileus diagnosis and the surgical procedures for management were enterolithotomy, one-stage surgery, and two-stage surgery. Enterolithotomy had lower morbidity and mortality than the other 2 procedures. The aim of gallstone ileus treatment is to release the obstruction, which is done through enterolithotomy. It is the recommended technique for gallstone ileus management because of its lower morbidity and mortality, compared with the other techniques.

A 60-year-old woman with a history of distal gastrectomy for gastric cancer presented with a chief complaint of epigastric pain. Duodenal ileus due to the migration of a gastric bezoar was diagnosed, and she was hospitalized. We performed endoscopic lithotripsy and injection of cola, but the bezoar migrated toward the anus. Her abdominal pain worsened the following day, and she was diagnosed with ileus induced by the gastric bezoar. After decompression with an ileus tube, 1000ml/day of cola was injected via the ileus tube, and the ileus resolved on the 5th day of therapy. Based on this experience, we believe that dissolution therapy with cola via an ileus tube is effective in the treatment of bezoar-induced small bowel ileus.

He presented with epigastric pain, vomiting, and low-grade fever. Plain abdominal radiography showed some intestinal gas and niveau, and he was admitted to our hospital with a diagnosis of ileus. The next day, the abdominal pain increased and was accompanied by muscular defense. Plain radiography and computed tomography of the abdomen were carried out, and an emergency laparotomy was performed under a diagnosis of panperitonitis due to a perforation of the gallbladder caused by acute emphysematous cholecystitis. The patient made favorable progress after the operation and was discharged on postoperative day 14. Percutaneous transhepatic gallbladder drainage has been increasingly performed for the treatment of acute emphysematous cholecystitis. but when a perforation of the gallbladder is suspected, a laparotomy first should be considered.

Postoperative ileus (POI) is a transient gastrointestinal (GI) dysmotility that commonly develops after abdominal surgery. YH12852, a novel, potent and highly selective 5-hydroxytryptamine 4 (5-HT 4 ) receptor agonist, has been shown to improve both upper and lower GI motility in various animal studies and may have applications for the treatment of POI. Here, we investigated the effects and mechanism of action of YH12852 in a guinea pig model of POI to explore its therapeutic potential. The guinea pig model of POI was created by laparotomy, evisceration, and gentle manipulation of the cecum for 60 seconds, followed by closure with sutures under anesthesia. Group 1 received an oral administration of vehicle or YH12852 (1, 3, 10 or 30 mg/kg) only, while POI Group 2 was intraperitoneally pretreated with vehicle or 5-HT 4 receptor antagonist GR113808 (10 mg/kg) prior to oral dosing of vehicle or YH12852 (3 or 10 mg/kg). Upper GI transit was evaluated by assessing the migration of a charcoal mixture in the small intestine, while lower GI transit was assessed via measurement of fecal pellet output (FPO). YH12852 significantly accelerated upper and lower GI transit at the doses of 3, 10, and 30 mg/kg and reached its maximal effect at 10 mg/kg. These effects were significantly blocked by pretreatment of GR113808 10 mg/kg. Oral administration of YH12852 significantly accelerates and restores delayed upper and lower GI transit in a guinea pig model of POI. This drug may serve as a useful candidate for the treatment of postoperative ileus. © 2017 John Wiley & Sons Ltd.

Gallstone ileus is a mechanical intestinal obstruction due to gallstone impaction within the gastrointestinal tract. Less than 1% of cases of intestinal obstruction are derived from this etiology. The symptoms and signs of gallstone ileus are mostly nonspecific. This entity has been observed with a higher frequency among the elderly, the majority of which have concomitant medical illness. Cardiovascular, pulmonary, and metabolic diseases should be considered as they may affect the prognosis. Surgical relief of gastrointestinal obstruction remains the mainstay of operative treatment. The current surgical procedures are: (1) simple enterolithotomy; (2) enterolithotomy, cholecystectomy and fistula closure (one-stage procedure); and (3) enterolithotomy with cholecystectomy performed later (two-stage procedure). Bowel resection is necessary in certain cases after enterolithotomy is performed. Large prospective laparoscopic and endoscopic trials are expected. PMID:26843914

Backgrounds/Aims Major hepato-pancreato-biliary (HPB) surgery is usually performed via an open method rather than a laparoscopic method. Postoperative ileus (POI) is a classic complication after open surgery. The purpose of this study was to determine whether polylactic film is useful in the prevention of POI. Methods A total of 179 patients who underwent major HPB surgery between 2005 and 2014, were retrospectively reviewed. A diagnosis of POI was made by a physical examination, laboratory, and radiological findings. Surgi-Wrap® polylactic film was preferentially used intraperitoneally by surgeons, just before wound closure. Results Major HPB surgery included pancreatoduodenectomy (n=48), distal or subtotal pancreatectomy (n=24), hepatectomy (n=67), other bile duct or gallbladder operations (n=35), and others (n=5). Although patients with polylactic film showed a significantly lower incidence of POI (n=3, 4.1% vs. n=14, 13.3%, p=0.041), they showed a significantly higher complication rate (n=20, 27.0% vs. n=19, 18.1%, p=0.004), particularly intra-abdominal fluid collection (n=7, 9.4% vs. n=2, 1.9%), and wound infections (n=6, 8.1% vs. n=3, 2.9%), than those who did not receive the film, respectively. Conclusions Although the polylactic film prevented POI, more complications other than POI were observed. Well-designed randomized controlled trials, using this anti-adhesive product, are needed to evaluate its effect on POI after major HPB surgery. PMID:28261699

Postoperative ileus (POI) is a common complication after spine surgery, with particularly high rates after adult spinal deformity surgery (ASD). Few investigations have been conducted, however, on predictors of POI following ASD. The objective of this investigation was to determine risk factors for POI in patients undergoing ASD. We also sought to determine the association between POI and in-hospital mortality, length of stay, and total charges. Data were obtained from the National/Nationwide Inpatient Sample, years 2010 - 2014. ASD patients aged ≥26 years-old were selected using ICD-9-CM codes. Multiple logistic and linear regression were utilized. In total, 59,410 patients were included in the analysis. 7.4% of patients experienced POI. On adjusted analysis, the following variables were associated with increased risk of POI: male sex (OR 1.43, CI 1.10 - 1.85), anterior surgical approach (OR 1.78, CI 1.22 - 2.60), 9+ levels fused (OR 1.84, CI 1.24 - 2.73), electrolyte disorders (OR 2.70, CI 2.15 - 3.39), and pathologic weight loss (OR 1.94, CI 1.08 - 3.46). POI was associated with significantly longer length of stay (+39%, CI 29% - 51%) and higher total charges (+23%, CI 14% - 31%). Risk factors for POI were identified. Patients suffering from ileus exhibited 2.9 days longer length of stay and ∼$80,000 higher total charges. These results may be applied clinically to identify patients at risk of POI and to consider addressing modifiable risk factors preoperatively. Future studies should be conducted with additional data to develop models capable of accurately predicting and preventing POI. Copyright © 2018 Elsevier Inc. All rights reserved.

To investigate the efficacy and safety of alvimopan, 12 mg, administered orally 30 to 90 minutes preoperatively and twice daily postoperatively in conjunction with a standardized accelerated postoperative care pathway for managing postoperative ileus after bowel resection. This multicenter, randomized, placebo-controlled, double-blind, phase 3 trial enrolled adult patients undergoing partial bowel resection with primary anastomosis by laparotomy and scheduled to receive intravenous, opioid-based, patient-controlled analgesia. A standardized accelerated postoperative care pathway including early ambulation, oral feeding, and postoperative nasogastric tube removal was used to facilitate gastrointestinal (GI) tract recovery in all of the patients. The primary end point was time to GI-2 recovery (toleration of solid food and first bowel movement). Secondary end points included time to GI-3 recovery (toleration of solid food and first flatus or bowel movement), hospital discharge order written, and actual hospital discharge. Postoperative length of hospital stay based on calendar day of hospital discharge order written, opioid consumption, and overall postoperative ileus-related morbidity were recorded. Alvimopan, 12 mg, was well tolerated and significantly accelerated GI-2 recovery, GI-3 recovery, and actual hospital discharge compared with a standardized accelerated postoperative care pathway alone (hazard ratio = 1.5, 1.5, and 1.4, respectively; P < .001 for all). Time to hospital discharge order written as measured by hazard ratio (1.4) and by postoperative calendar days (mean for alvimopan, 5.2 days; mean for placebo, 6.2 days) was also accelerated. Opioid consumption was comparable between groups, and alvimopan was associated with reduced postoperative ileus-related morbidity compared with placebo. Alvimopan, 12 mg, administered 30 to 90 minutes before and twice daily after bowel resection is well tolerated, accelerates GI tract recovery, and reduces postoperative

Postoperative ileus (POI) is a common complication after major abdominal surgery. Gum chewing has been shown to stimulate bowel motility and decrease duration of POI after abdominal surgery. We evaluated the effect of gum chewing in reducing the time to first flatus and on oral calorie intake in patients undergoing living or deceased donor liver transplantation. Patients were randomized into the sham feeding group or the control group. The sham feeding group chewed two pieces of xylitol flavored gum for 15 minutes, three times a day after extubation until oral nutrition was tolerated. The control group received the same routine care except for the gum chewing. Fifty-nine patients were randomized into the sham feeding group (n=30) or the control group (n=29). There was no difference in the time to first flatus (72 [66.1-82.9] hours vs 69.0 [57.6-77.2] hours, P=.422). Cumulative energy intake (2.8 [5.8-23.2] % vs 10.0 [8.5-15.9] %, P=.695) and length of intensive care unit stay (4.2 [3.9-5.3] days vs 4.0 [6.7-4.5] days, P=.077) were also similar. In conclusion, sham feeding with gum chewing did not shorten the duration of POI nor facilitate oral intake after liver transplantation.

Chewing gum, as an alternative to sham feeding, had been shown to hasten the recovery of gut function following abdominal surgery. However, conclusions remained contradictory. We sought to conduct an updated meta-analysis to evaluate the efficacy of gum chewing in alleviating ileus following colorectal surgery. We searched PubMed, EMBASE, and Cochrane Library Databases through February 2017 to identify randomized controlled trials (RCTs) evaluating the efficacy of the additional use of chewing gum following colorectal surgery. After screening for inclusion, data extraction, and quality assessment, meta-analysis was conducted by the Review Manager 5.3 software. The outcomes of interest were the time to first flatus, time to first bowel movement, length of hospital stay, and some clinically relevant parameters. We also performed subgroup analyses according to the type of surgical approaches or on trials that adopted enhanced recovery after surgery (ERAS) protocol or sugared gum. A total of 18 RCTs, involving 1736 patients, were included. Compared with standardized postoperative care, Chewing gum resulted in a shorter passage to first flatus [WMD = -8.81, 95%CI: (-13.45, -4.17), P = 0.0002], earlier recovery of bowel movement [WMD = -16.43, 95%CI: (-22.68, -10.19), P < 0.00001], and a reduction in length of hospital stay [WMD = -0.89, 95%CI: (-1.72, -0.07), P = 0.03]. Chewing gum was also associated with a lower risk of postoperative ileus [OR = 0.41, 95%CI: (0.23, 0.73), P = 0.003]. No evidence of significant advantages in overall postoperative complication, nausea, vomiting, bloating, readmission and reoperation towards the addition of chewing gum was observed. Subgroup analyses all favored gum chewing. However, the findings are hampered by the significant heterogeneity between trials. Based on current evidence, chewing gum offers an inexpensive, well-tolerated, safe and effective method to ameliorate ileus following colorectal surgery. However

Daikenchuto (DKT), a gastrointestinal prokinetic Japanese herbal medicine, is prescribed for patients with postoperative ileus (POI) and adhesive bowel obstruction following abdominal surgery. Several mechanisms for the amelioration of POI by DKT have been suggested; however, it has remained unclear whether DKT shows anti-inflammatory effects in POI. In the present study, we investigated the effects of DKT in a mouse POI model and attempted to clarify the detailed mechanisms of action. Intestinal manipulation (IM) was applied to the distal ileum of mice. DKT was administered orally to the animals 4 times before and after IM. Gastrointestinal transit in vivo, leukocyte infiltration, cytokine mRNA expression and gastrointestinal motility were analyzed. We also investigated the effects of the α7nAChR antagonist methyllycaconitine citrate (MLA) on the DKT-mediated ameliorative action against POI, and we studied the effects of DKT on inflammatory activity in α7nAChR knockout mice. DKT treatment led to recovery of the delayed intestinal transit induced by IM. DKT significantly inhibited the infiltration of neutrophils and CD68-positive macrophages, and inhibited mRNA expressions of TNF-α and MCP-1. MLA significantly reduced the anti-inflammatory action of DKT, and the amelioration of macrophage infiltration by DKT was partially suppressed in α7nAChR knockout mice. In conclusion, in addition to the gastrointestinal prokinetic action, DKT serves as a novel therapeutic agent for POI characterized by its anti-inflammatory potency. The DKT-induced anti-inflammatory activity may be partly mediated by activation of α7nAChR.

Postoperative ileus (POI) is common following bowel resection for radical cystectomy with ileal conduit (RCIC). We investigated perioperative factors associated with prolonged POI following RCIC, with specific focus on opioid-based analgesic dosage. From March 2007 to January 2013, 78 open RCICs and 26 robot-assisted RCICs performed for bladder carcinoma were identified with adjustment for age, gender, American Society of Anesthesiologists grade, and body mass index (BMI). Perioperative records including operative time, intraoperative fluid excess, estimated blood loss, lymph node yield, and opioid analgesic dose were obtained to assess their associations with time to passage of flatus, tolerable oral diet, and length of hospital stay (LOS). Prior to general anaesthesia, patients received epidural patient-controlled analgesia (PCA) consisted of fentanyl with its dose adjusted for BMI. Postoperatively, single intravenous injections of tramadol were applied according to patient desire. Multivariate analyses revealed cumulative dosages of both PCA fentanyl and tramadol injections as independent predictors of POI. According to surgical modality, linear regression analyses revealed cumulative dosages of PCA fentanyl and tramadol injections to be positively associated with time to first passage of flatus, tolerable diet, and LOS in the open RCIC group. In the robot-assisted RCIC group, only tramadol dose was associated with time to flatus and tolerable diet. Compared to open RCIC, robot-assisted RCIC yielded shorter days to diet and LOS; however, it failed to shorten days to first flatus. Reducing opioid-based analgesics shortens the duration of POI. The utilization of the robotic system may confer additional benefit.

Background Delayed gastric emptying is a common disorder with few effective therapeutic options. The goal of this study was to investigate whether ipamorelin, a synthetic peptidomimetic that acts on the ghrelin receptor, accelerates gastric emptying in a rodent model of gastroparesis induced by abdominal surgery and intestinal manipulation. Methods Fasted adult male rats were subjected to laparotomy and intestinal manipulation. Following the surgery rats received ipamorelin (0.014–0.14 µmol/kg) or vehicle control via intravenous administration. Gastric emptying was measured by the percent of total recovered radioactivity remaining in the stomach 15 minutes after intragastric gavage of 1.5 mL of 99mTc (technicium-99m) sulfur colloid in 0.5% methylcellulose. In a separate group of rats subjected to laparotomy and intestinal manipulation, the gastric fundus was isolated and tissue segments were suspended in an organ bath to assess the effect of ipamorelin (1 µM) on gastric smooth muscle contractility induced by acetylcholine and electrical field stimulation. Results Abdominal surgery caused a delay in gastric emptying with 78% ± 5% of the meal remaining in the stomach in vehicle controls. Ipamorelin (0.014 µmol/kg intravenous) resulted in a significant acceleration (P < 0.05 vs vehicle-treated rat) of gastric emptying with 52% ± 11% of the meal remaining in the stomach compared to nonsurgical control animals with 44% ± 6%. Following abdominal surgery and intestinal manipulation, isolated preparations of gastric smooth muscle exhibited a marked inhibition of acetylcholine and electrical field stimulation-induced contractile responses, which were reversed by ipamorelin and ghrelin. Conclusion These results suggest that ipamorelin accelerates gastric emptying in a rodent model of postoperative ileus through the stimulation of gastric contractility by activating a ghrelin receptor-mediated mechanism involving cholinergic excitatory neurons.

Epidural anaesthesia and analgesia - effects on surgical stress responses and implications for postoperative nutrition.

PubMed

Holte, K; Kehlet, H

2002-06-01

Surgical injury leads to an endocrine-metabolic and inflammatory response with protein catabolism, increased cardiovascular demands, impaired pulmonary function and paralytic ileus, the most important release mechanisms being afferent neural stimuli and inflammatory mediators. Epidural local anaesthetic blockade of afferent stimuli reduces endocrine metabolic responses, and improve postoperative catabolism. Furthermore, dynamic pain relief is achieved with improved pulmonary function and a pronounced reduction of postoperative ileus, thereby providing optimal conditions for improved mobilization and oral nutrition, and preservation of body composition and muscle function. Studies integrating continuous epidural local anaesthetics with enforced early nutrition and mobilization uniformly suggest an improved recovery, decreased hospital stay and convalescence. Epidural local anaesthetics should be included in a multi-modal rehabilitation programme after major surgical procedures in order to facilitate oral nutrition, improve recovery and reduce morbidity.

Special postoperative diet orders: Irrational, obsolete, and imprudent.

There are no indications to prescribed special diets for postoperative patients. Low-sodium and low-fat or low-cholesterol diets are examples of restricted diets, especially in patients with heart disease and atherosclerosis. These restricted diets are unpalatable. Postoperative nausea, paralytic ileus, and vomiting caused by residual anesthetic effects and opioids used for pain control further contribute to the problem. Long-term adherence to these diets is necessary to derive benefits. Prescribing regular and palatable diets in the immediate postoperative period to meet protein and energy goals is important for wound healing and is commensurate with best clinical practices. In the following, we review the pertinent literature and offer clinical evidence that routine special diet orders for postoperative patients are not necessary. Published by Elsevier Inc.

Bouveret syndrome: gallstone ileus of the duodenum.

Englert, Zachary P; Love, Katie; Marilley, Mark D; Bower, Curtis E

2012-10-01

This is a case of a 59-year-old woman with Bouveret syndrome. An initial endoscopic approach to management is described. Gallstone ileus occurs when a gallstone passes from a cholecystoduodenal fistula or a choledochoduodenal fistula into the gastrointestinal tract and causes obstruction, usually at the ileocecal valve. Bouveret syndrome is a variant of gallstone ileus where the gallstone lodges in the duodenum or pylorus causing a gastric outlet obstruction. The endoscopic and surgical management of this process are important to keep in mind and may be evolving as endoscopic therapies improve.

Cystic fibrosis (CF) pigs develop disease with features remarkably similar to those in people with CF, including exocrine pancreatic destruction, focal biliary cirrhosis, micro-gallbladder, vas deferens loss, airway disease, and meconium ileus. Whereas meconium ileus occurs in 15% of babies with CF, the penetrance is 100% in newborn CF pigs. We hypothesized that transgenic expression of porcine CF transmembrane conductance regulator (pCFTR) cDNA under control of the intestinal fatty acid–binding protein (iFABP) promoter would alleviate the meconium ileus. We produced 5 CFTR–/–;TgFABP>pCFTR lines. In 3 lines, intestinal expression of CFTR at least partially restored CFTR-mediated anion transport and improved the intestinal phenotype. In contrast, these pigs still had pancreatic destruction, liver disease, and reduced weight gain, and within weeks of birth, they developed sinus and lung disease, the severity of which varied over time. These data indicate that expressing CFTR in intestine without pancreatic or hepatic correction is sufficient to rescue meconium ileus. Comparing CFTR expression in different lines revealed that approximately 20% of wild-type CFTR mRNA largely prevented meconium ileus. This model may be of value for understanding CF pathophysiology and testing new preventions and therapies. PMID:23676501

Severely malnourished children aged under five years requiring hospital admission for diarrheal illness frequently develop ileus during hospitalization with often fatal outcomes. However, there is no data on risk factors and outcome of ileus in such children. We intended to evaluate predictive factors for ileus during hospitalization and their outcomes. This was a retrospective chart review that enrolled severely malnourished children under five years old with diarrhea, admitted to the Dhaka Hospital of the International Centre for Diarrhoeal Disease Research, Bangladesh between April 2011 and August 2012. We used electronic database to have our chart abstraction from previously admitted children in the hospital. The clinical and laboratory characteristics of children with (cases = 45), and without ileus (controls = 261) were compared. Cases were first identified by observation of abnormal bowel sounds on physical examination and confirmed with abdominal radiographs. For this comparison, Chi-square test was used to measure the difference in proportion, Student's t-test to calculate the difference in mean for normally distributed data and Mann-Whitney test for data that were not normally distributed. Finally, in identifying independent risk factors for ileus, logistical regression analysis was performed. Ileus was defined if a child developed abdominal distension and had hyperactive or sluggish or absent bowel sound and a radiologic evidence of abdominal gas-fluid level during hospitalization. Logistic regression analysis adjusting for potential confounders revealed that the independent risk factors for admission for ileus were reluctance to feed (odds ratio [OR] = 3.22, 95% confidence interval [CI] = 1.24-8.39, p = 0.02), septic shock (OR = 3.62, 95% CI = 1.247-8.95, p<0.01), and hypokalemia (OR = 1.99, 95% CI = 1.03-3.86, p = 0.04).

BACKGROUND This study aimed to determine the effects of use of a local hemostatic gelatin sponge (GS) on postoperative morbidity in patients undergoing cesarean section (CS). MATERIAL AND METHODS The records of 318 patients who underwent CS surgery were retrospectively evaluated. Group 1 consisted of 59 patients with gelatin sponge (GS) applied, and Group 2 consisted of 259 patients with no GS applied. The groups were compared for time to the first flatus, nausea and vomiting, requirement for anti-emetic drugs, development of postoperative ileus, and the length of hospitalization. RESULTS The patients in Group 1 and Group 2 were statistically similar in mean age, gravida, parity, and body mass index (BMI) (p=0.352, p=0.275, p=0.458, and p=0.814, respectively). No significant difference was determined in the number of patients with nausea, vomiting, anti-emetic drug use, febrile morbidity, and postoperative ileus (p=0.063, p=0.436, p=328, p=0.632, and p=0.179, respectively). Time to the first flatus and length of hospitalization were significantly longer in Group 2 (p<0.001 and p<0.001, respectively). CONCLUSIONS Delay in recovery of bowel motility may be due to the local hypersensitivity reaction caused by GS and/or dislocation of this local hemostat. Women who receive gelatin sponge treatment during CS should be monitored closely for the recovery of postoperative intestinal motility.

Objective Postoperative ileus (POI), the most frequent complication after intestinal surgery, depends on dendritic cells (DCs) and macrophages. Here, we have investigated the mechanism that activates these cells and the contribution of the intestinal microbiota for POI induction. Design POI was induced by manipulating the intestine of mice, which selectively lack DCs, monocytes or macrophages. The disease severity in the small and large intestine was analysed by determining the distribution of orally applied fluorescein isothiocyanate-dextran and by measuring the excretion time of a retrogradely inserted glass ball. The impact of the microbiota on intestinal peristalsis was evaluated after oral antibiotic treatment. Results We found that Cd11c-Cre+ Irf4flox/flox mice lack CD103+CD11b+ DCs, a DC subset unique to the intestine whose function is poorly understood. Their absence in the intestinal muscularis reduced pathogenic inducible nitric oxide synthase (iNOS) production by monocytes and macrophages and ameliorated POI. Pathogenic iNOS was produced in the jejunum by resident Ly6C– macrophages and infiltrating chemokine receptor 2-dependent Ly6C+ monocytes, but in the colon only by the latter demonstrating differential tolerance mechanisms along the intestinal tract. Consistently, depletion of both cell subsets reduced small intestinal POI, whereas the depletion of Ly6C+ monocytes alone was sufficient to prevent large intestinal POI. The differential role of monocytes and macrophages in small and large intestinal POI suggested a potential role of the intestinal microbiota. Indeed, antibiotic treatment reduced iNOS levels and ameliorated POI. Conclusions Our findings reveal that CD103+CD11b+ DCs and the intestinal microbiome are a prerequisite for the activation of intestinal monocytes and macrophages and for dysregulating intestinal motility in POI.

To evaluate the preventive effect of Zusanli (ST36) acupoint injections with various agents, for postoperative ileus (POI). We searched electronic databases for randomized controlled trials from inception to 1st February 2015 evaluating ST36 acupoint injection for preventing POI. Revman 5.2.0 was used for data analysis with effect estimates presented as mean difference (MD) with 95% confidence interval (CI). Statistical heterogeneity was tested using I(2) (defined as significant if I(2)>75%). We used a random effects model (REM) for pooling data with significant heterogeneity. Thirty trials involving 2967 participants were included. All trials were assessed as high risk of bias (poor methodological quality). For time to first flatus, meta-analysis favored ST36 acupoint injection of neostigmine (MD -20.70h, 95% CI -25.53 to -15.87, 15 trials, I(2)=98%, REM), vitamin B1 (MD -11.22h, 95% CI -17.01 to -5.43, 5 trials, I(2)=98%, REM), and metoclopramide (MD -15.65h, 95% CI -24.77 to -6.53, 3 trials, I(2)=94%, REM) compared to usual care alone. Meta-analysis of vitamin B1 favored ST36 acupoint injection compared to intra-muscular injection (MD -17.21h, 95% CI -21.05 to -13.36, 4 trials, I(2)=89%, REM). Similarly, for time to bowel sounds recovery and first defecation, ST36 acupoint injection also showed positive effects. ST36 acupoint injections with various agents may have a preventive effect for POI. Safety is inconclusive as few of included trials reported adverse events. Due to the poor methodological quality and likely publication bias further robust clinical trials are required to arrive at a definitive conclusion. Copyright © 2015 Elsevier Ltd.

Effects of nerve growth factor antagonist K252a on peritoneal mast cell degranulation: implications for rat postoperative ileus.

PubMed

Berdún, Sergio; Rychter, Jakub; Vergara, Patri

2015-11-15

Stabilization of mast cell (MC) degranulation has been proposed to prevent postoperative ileus (POI). Nerve growth factor (NGF) mediates MC degranulation. The aim of the study was to evaluate whether NGF receptor antagonist K252a acts as a MC stabilizer in vitro and in vivo model of POI. Peritoneal mast cells (PMCs) were obtained from Sprague-Dawley rats and were incubated with K252a and exposed to NGF or Compound 48/80 (C48/80). MC degranulation was assessed by β-hexosaminidase assay. POI was induced in rats by intestinal manipulation (IM). Rats were pretreated with K252a (100 μg/kg sc) 20 min prior to POI induction. At 20 min after IM, release of rat mast cell protease 6 (RMCP-6) was evaluated in peritoneal lavage. At 24 h, intestinal transit (IT) and gastric emptying (GE) were evaluated. Ileal inflammation was assessed by myeloperoxidase (MPO) activity, expression of IL-6, NGF, TrkA, RMCP-2 and 6, and MC density within the full-thickness ileum. C48/80 and NGF evoked degranulation of PMCs in a dose-dependent manner. K252a prevented NGF-evoked, but not C48/80-evoked, MC degranulation. IM evoked the release of peritoneal RMCP-6 and subsequently delayed IT and GE. IM increased MPO activity and expression of IL-6. In IM rats, K252a prevented upregulation of IL-6 expression and reduced TrkA. IT, GE, and inflammation were not affected by K252a. K252a inhibited NGF-evoked degranulation of PMCs in vitro. In vivo, K252a decreased IL-6 and PMC degranulation. This may be of relevance for the development of new therapeutic targets for POI. Copyright © 2015 the American Physiological Society.

A gallstone colonic ileus is a very rare condition. The case is reported of an 87 year-old patient who came to the Emergency Department due to an intestinal obstruction of several days onset, which was caused by a gallstone affected sigmoid colon. Colonic gallstone ileus is a rare disease that usually occurs in older patients due to the passage of large gallstone directly from the gallbladder to colon, through a cholecystocolonic fistula. It has a high morbidity and mortality. Copyright © 2016 Academia Mexicana de Cirugía A.C. Publicado por Masson Doyma México S.A. All rights reserved.

We present a patient who developed a paralytic ileus requiring extended hospitalization. Providers should minimize antipsychotic and concurrent anticholinergic medications, consider prophylactic bowel regimens and monitor for constipation. Copyright © 2011 Elsevier Inc.

Acupuncture is a therapy effective in treating postoperative ileus (POI); its underlying mechanisms remain unclear. MicroRNAs (miRNAs) participate in inflammation and injury to the interstitial cells of Cajal (ICCs), both of which are considered to be contributors to POI. C-kit, encoding KIT, a specific marker of ICCs, is predicted to be targeted by miR-19a, an inflammation-related miRNA. Therefore, we investigated a possible link between inflammation, miR-19a, and ICCs in POI, as well as the mechanism by which these factors are affected by acupuncture. The effects of acupuncture on POI were assessed in patients after colorectal resection and in colocolic anastomosis mice. Immunofluorescence staining demonstrated that KIT[Formula: see text]/ano1[Formula: see text] ICCs dramatically decreased around the colonic incision in mice, which was negatively correlated with the pronounced increase in macrophage. However, this decrease was not due to apoptosis. IL-6R was expressed in ICCs, and IL-6 level was significantly increased, as measured by ELISA, in accompaniment with high miR-19a expression. The increase in IL-6 and miR-19a levels was negatively correlated with the decrease in KIT[Formula: see text]/ano1[Formula: see text] ICCs. A luciferase reporter assay demonstrated that miR-19a directly targeted C-kit, indicating that miR-19a caused ICC damage. Interestingly, acupuncture inhibited macrophage activation, IL-6 release, and miR-19a upregulation, while promoting KIT and ano1 restoration in ICCs. High serum miR-19a level in patients after colorectal resection was also reduced by acupuncture. Conclusively, the IL-6 released by macrophages during gastrointestinal surgery upregulated miR-19a, which downregulated KIT in ICCs and finally resulted in POI. Acupuncture can interfere with the "IL-6-miR-19a-KIT" axis, suggesting that it may be a therapeutic mechanism that works against POI.

We evaluated the effect of alvimopan treatment vs placebo on health care utilization and costs related to gastrointestinal recovery in patients treated with radical cystectomy in a randomized, phase 4 clinical trial. Resource utilization data were prospectively collected and evaluated by cost consequence analysis. Hospital costs were estimated from 2012 Medicare reimbursement rates and medication wholesale acquisition costs. Differences in base case mean costs between the study cohorts for total postoperative ileus related costs (hospital days, study drug, nasogastric tubes, postoperative ileus related concomitant medication and postoperative ileus related readmissions) and total combined costs (postoperative ileus related, laboratory, electrocardiograms, nonpostoperative ileus related concomitant medication and nonpostoperative ileus related readmission) were evaluated by probabilistic sensitivity analysis using a bootstrap approach. Mean hospital stay was 2.63 days shorter for alvimopan than placebo (mean±SD 8.44±3.05 vs 11.07±8.23 days, p=0.005). Use of medications or interventions likely intended to diagnose or manage postoperative ileus was lower for alvimopan than for placebo, eg total parenteral nutrition 10% vs 25% (p=0.001). Postoperative ileus related health care costs were $2,340 lower for alvimopan and mean total combined costs were decreased by $2,640 per patient for alvimopan vs placebo. Analysis using a 10,000-iteration bootstrap approach showed that the mean difference in postoperative ileus related costs (p=0.04) but not total combined costs (p=0.068) was significantly lower for alvimopan than for placebo. In patients treated with radical cystectomy alvimopan decreased hospitalization cost by reducing the health care services associated with postoperative ileus and decreasing the hospital stay.

Ghrelin agonist TZP-101 is a potent prokinetic. This phase 2b study evaluated TZP-101 safety and efficacy in postoperative ileus management. Adults undergoing open partial colectomy were adaptively randomized to receive 20, 40, 80, 160, 320, 480 or 600 microg/kg TZP-101 (n = 168) or the placebo (n = 68) by 30-minute IV infusion within 1 hour of surgical closure and then daily for up to 7 days. The primary efficacy end point was the time to first bowel movement. Secondary end points included the percentage of patients with return of gastrointestinal function within 72 hours, and the time to readiness for discharge. TZP-101 accelerated the time to first bowel movement in all groups, with Cox proportional hazard ratios of 1.57 (P = .056) for the low-efficacious dose (80 microg/kg) and 1.67 (P = .03) for the most efficacious dose (480 microg/kg). Using Kaplan-Meier analysis, the median time to first bowel movement was reduced in all TZP-101 groups by 10 to 22 hours vs. the placebo. A greater number of patients who received TZP-101 achieved recovery (P

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.

For radical cystectomy, historical practice trends have favored the use of preoperative bowel preparations to reduce complications, including surgical site infections, ileus, and anastomotic leaks. However, emerging data has questioned this practice. Postoperative cystectomy care also remains in flux, as new pharmacologic agents that may potentiate earlier return of bowel function are studied. We review the current literature with regards to preoperative and postoperative cystectomy bowel management.

Previous incomplete studies investigating the potential of chewing gum (CG) in patients undergoing colorectal resection did not obtain definitive conclusions. This updated meta-analysis was therefore conducted to evaluate the effect and safety of CG versus standard postoperative care protocols (SPCPs) after colorectal surgery. Total 26 RCTs enrolling 2214 patients were included in this study. The CG can be well-tolerated by all patients. Compared with SPCPs, CG was associated with shorter time to first flatus (weighted mean difference (WMD) -12.14 (95 per cent c.i. -15.71 to -8.56) hours; P < 0.001), bowl movement (WMD -17.32 (-23.41 to -11.22) hours; P < 0.001), bowel sounds (WMD -6.02 (-7.42 to -4.63) hours; P < 0.001), and length of hospital stay (WMD -0.95 (-1.55 to -0.35) days; P < 0.001), a lower risk of postoperative ileus (risk ratio (RR) 0.61 (0.44 to 0.83); P = 0.002), net beneficial and quality of life. There were no significant differences between the two groups in overall complications, nausea, vomiting, bloating, wound infection, bleeding, dehiscence, readmission, reoperation, mortality. The potentially eligible randomized controlled trials (RCTs) that compared CG with SPCPs for colorectal resection were searched in PubMed, Embase, Cochrane library, China National Knowledge Infrastructure (CNKI), and Chinese Wanfang databases through May 2016. The trial sequential analysis was adopted to examine whether a firm conclusion for specific outcome can be drawn. CG is benefit for enhancing return of gastrointestinal function after colorectal resection, and may be associated with lower risk of postoperative ileus.

Introduction Postoperative ileus (POI) is a frequent complication after abdominal surgery (AS). Until today, neither a prophylaxis nor an evidence-based therapy exists. This originates from the absence of objective parameters evaluating the severity and duration of POI resulting in clinical trials of modest quality. The SmartPill®, a capsule which frequently measures pH value, temperature and intraluminal pressure after swallowing, offers an elegant option for analysing gastrointestinal (GI) transit times and smooth muscle activity in vivo. As the use in patients in the first months after AS is not covered by the marketing authorisation, we aim to investigate the safety and feasibility of the SmartPill® immediately after surgery. Additionally, we analyse the influence of prokinetics and laxatives as well as standardised physiotherapy on postoperative bowel contractility, as scientific evidence of its effects is still lacking. Methods and analysis The PIDuSA study is a prospective, single-centre, two-arm, open-label trial. The SmartPill® will be applied to 55 patients undergoing AS having a high risk for POI and 10 patients undergoing extra-abdominal surgery rarely developing POI. The primary objective is the safety of the SmartPill® in patients after surgery on the basis of adverse device effects/serious adverse device effects (ADE/SADE). The sample size suggests that events with a probability of 3% could be seen with a certainty of 80% for at least once in the sample. Secondary objective is the analysis of postoperative intestinal activity in the GI tract in both groups. Furthermore, clinical signs of bowel motility disorders will be correlated to the data measured by the SmartPill® to evaluate its significance as an objective parameter for assessing POI severity. Additionally, effects of prokinetics, laxatives and physiotherapy on postoperative peristaltic activity recorded by the SmartPill® will be analysed. Ethics and dissemination The protocol was

Cholesterol crystal embolization (CCE) is a rare systemic embolism caused by formation of cholesterol crystals from atherosclerotic plaques. CCE usually occurs during vascular manipulation, such as vascular surgery or endovascular catheter manipulation, or due to anticoagulation or thrombolytic therapy. We report a rare case of intestinal obstruction caused by spontaneous CCE. An 81-year-old man with a history of hypertension was admitted for complaints of abdominal pain, bloating, and anorexia persisting for 4 mo. An abdominal computed tomography revealed intestinal ileus. His symptoms were immediately relieved by an ileus tube insertion, and he was discharged 6 d later. However, these symptoms immediately reappeared and persisted, and partial resection of the small intestine was performed. A histopathological examination indicated that small intestine obstruction was caused by CCE. At the 12-mo follow-up, the patient showed no evidence of CCE recurrence. Thus, in cases of intestinal obstruction, CCE should also be considered.

Air Swallowing Caused Recurrent Ileus in Tourette’s Syndrome

PubMed Central

Frye, Richard E.; Hait, Elizabeth J.

2008-01-01

This report describes an adolescent boy who has Tourette’s syndrome and developed a subtle but significant increase in vocal tics after an 8-month respite. The increase in vocal tics was associated with an acute increase in psychological stressors and resulted in recurrent air swallowing, which, in turn, caused abdominal cramping, eructation, and flatus, eventually leading to aeroenteria. Air swallowing was recognized only after a second hospital admission for recurrent ileus. Air swallowing and associated symptoms were mitigated by reinstitution of psychopharmacologic treatment and an increase in the patient’s self-awareness of the air-swallowing behavior. Clinically significant air swallowing has not been described previously in Tourette syndrome or a tic disorder. This case is important for pediatricians and pediatric gastroenterologists because either may be the first to evaluate a child or an adolescent with unexplained recurrent ileus. This report also documents the importance of the connection between the brain and the body. PMID:16651280

Although it has been widely demonstrated that administration of Daikenchuto (DKT), a traditional Japanese herbal medicine, improves gastrointestinal (GI) motility in patients undergoing abdominal surgery, few studies have investigated the efficacy of perioperative DKT administration for relief of postoperative ileus (PI) in patients undergoing surgery for GI cancer. Therefore, the aim of this study was to investigate whether perioperative administration of DKT relieves PI in patients with GI cancer. We performed a comprehensive electronic search of the literature (Cochrane Library, PubMed, the Web of Science and ICHUSHI) up to December 2016 to identify studies that had shown the efficacy of perioperative DKT administration for relief of PI in patients with GI cancer. To integrate the individual effect of DKT, a meta-analysis was performed using random-effects models to calculate the risk ratio (RR) and 95% confidence interval (CI), and heterogeneity was analyzed using I 2 statistics. Seven studies involving a total of 1,134 patients who had undergone GI cancer surgery were included in this meta-analysis. Among 588 patients who received DKT perioperatively, 67 (11.4%) had PI, whereas among 546 patients who did not receive DKT perioperatively, 87 (15.9%) had PI. Perioperative administration of DKT significantly reduced the occurrence of PI (RR=0.58, 95% CI=0.35-0.97, p=0.04, I 2 =48%) in comparison to patients who did not receive DKT or received placebo. The result of this meta-analysis suggests that perioperative administration of DKT relieves PI in patients undergoing surgery for GI cancer.

Postoperative paralytic ileus follows all significant gastrointestinal surgery. Its duration is variable and has led to a variety of empirical and time-consuming oral fluid regimens. We have compared a traditional method of fluid administration with an unstructured, simpler, patient-determined approach. A series of 102 patients on a general surgical ward who required intravenous fluids on the day after surgery were randomised by a closed envelope system to one of two protocols and followed prospectively. Of these, 12 patients were erroneously randomised or unable to fulfil trial requirements. The first, 'regulated' group (n = 41) received hourly aliquots of oral fluid as determined by twice daily ward rounds according to ward routine. The second, 'unregulated' group (n = 49) were given a jug of water and instructed to drink as desired. Patients in the regulated group received less of their postoperative fluids by the oral route at all stages of recovery but there were no significant differences in the mean durations of intravenous therapy, nasogastric intubation or hospital stay. Postoperative complication and mortality rates were also similar. Patients who underwent gastric or duodenal procedures (n = 14) showed a similar pattern of results. We conclude that 'patient-determined' regulation of postoperative oral fluid intake is safe and effective and may greatly simplify ward management.

To report about an additional case of biliary ileus after bariatric surgery is reported and extensively reviewing the literature on this topic. We reviewed the literature and found three cases of gallstone ileus (GI) that occurred after bariatric surgery. A 41 year old patient presented a GI eight years after a biliointestinal bypass (BIB) for morbid obesity. The patient complained of abdominal pain for two weeks. Computed tomography (CT) and abdominal ultrasound (US) allowed a preoperative diagnosis of GI and planning of surgical strategy. Surgical treatment was carried out through laparoscopic-assisted enterolithotomy alone procedure. This choice is supported discussing the related issues: morbidity, potential recurrence, eventual developing of gallbladder carcinoma. It is the first reported case of GI after BIB preoperatively diagnosed through CT scan and US, and treated with a laparoscopic assisted approach. Additional considerations concerning preoperative diagnosis, surgical strategy, technical details and follow-up can be usefully applied even in non post-bariatric biliary ileus.

The authors report their experience with 33 tetraplegics undergoing surgery. The operations were varied, endoscopic (resection of the bladder neck, of the prostate or striate sphincter, lithot-itiasis) or surgical (lombotomies, transintentinal cutaneous ureterostomies). The post-operative course may be dramatic or even fatal (acute hypertension with cerebral haemorrhage). Respiratory insufficiency poses no particular problem and can be controlled. Epidural anaesthesia maintained for several days makes it possible to avoid the more serious problems: -- autonomic hyperreflectivity, -- delayed resolution of ileus and digestive complication. The authors hence use epidural anaesthesia routinely and are satisfied with the technique.

Rectus sheath catheter infusions for post-operative pain management.

PubMed

Layzell, Mandy

2014-06-24

Managing pain following major abdominal surgery remains a challenge. Traditionally, patient-controlled analgesia (PCA) or epidural analgesia have been used, which have improved post-operative pain and the patient experience, but have presented some problems in recovery. PCA can cause adverse effects, including sedation, nausea, vomiting, and prolonged gastric ileus. While epidurals do have some advantages over PCA, there are risks involved related to catheter insertion and adverse effects, such as hypotension and motor blocks which limit mobility. This article examines rectus sheath catheter infusions, a relatively new and alternative technique to epidural analgesia, and presents some early audit data related to pain scores, analgesic use and mobility.

Prolonged ileus as a sole manifestation of pseudomembranous enterocolitis.

Pseudomembranous colitis usually manifests as fever and diarrhea in hospitalized patients treated with systemic antibiotics. We present a case that represents a unique variant. The 44-year-old man suffered of several weeks of abdominal pain, low-grade fever, nausea, vomiting, and lack of bowel movements. Upper gastrointestinal barium swallow and passage series revealed evidence of severe intestinal hypomotility. A thorough evaluation for the cause of the patient's ileus and abdominal pain was unrevealing, and symptomatic treatment was ineffective. Following the administration of opiates and dietary fiber supplementation the patient's abdominal pain and distention rapidly worsened, requiring an urgent subtotal colectomy. The macroscopic and microscopic appearance of the excised colon as well as results of the colonic cytotoxin essay and fecal enzyme-linked immunosorbent assay essay confirmed the diagnosis of severe Clostridium difficile induced pseudomembranous colitis as the cause of the patient's illness. To our knowledge, this is the first reported case of Clostridium-difficile induced disease consisting of prolonged ileus in the absence of diarrhea in a patient not previously taking antibiotics.

Intestinal pseudo-obstruction is considered to be one of the most frequent gastrointestinal manifestations of myasthenia gravis, accompanied by the presence of neoplasia of the thymus gland in the vast majority of the cases presented in the international literature. Despite the fact that myasthenia gravis has been implicated to be the cause of recurrent episodes of intestinal pseudo-obstruction, adhesive ileus has never been reported to complicate this - in any sense rare - condition. We present a unique case of a patient with myasthenia gravis, free of thymus neoplasia, who was submitted to emergency surgery due to the presence of extended adhesive ileus as a complication of chronic intestinal functional obstruction.

To compare sugammadex with conventional reversal of neuromuscular block in terms of postoperative gastrointestinal motility. Double blinded, randomized, controlled clinical trial. Operating room, postoperative recovery area. Seventy-two patients with ASA physical status I or II, scheduled for total thyroid surgery were studied. When 4 twitches were observed on train-of-four stimulation, neuromuscular block was reversed conversatively in the control group, and with sugammadex in the study group. Time to first flatus and feces, incidence of postoperative nausea, vomiting, diarrhea and constipation were collected. Median time of first flatus was 24 hours (18-32 [10-36]) in the neostigmine group, and 24 (18-28 [12-48]) in the sugammadex group (P > .05). Median (IQR) time of first feces was 24 hours (18-36 [10-48]) in neostigmine group, 32 hours (28-36 [12-72]) in sugammadex group (P > .05). There were no occurrences of nausea, vomiting, diarrhea, or constipation. Sugammadex may be safely used in cases where postoperative ileus is expected. Copyright © 2016 Elsevier Inc.

We identified pediatric UC and CD patients treated with vedolizumab at our institution from 2014 to 2016. We compared postoperative outcomes in the vedolizumab exposed group to a cohort of vedolizumab naïve patients who required diverting ileostomy. Of the 31 patients who were treated with vedolizumab, 13 patients required surgery. Eight of 13 (62%) vedolizumab exposed patients had a postoperative complication, including mucocutaneous separation at the stoma (3), readmission for pain/dehydration (2), bowel obstruction at the ostomy, and intraoperative colonic perforation. In comparison, four of 16 (25%) vedolizumab naive patients had a postoperative complication, including readmission for ileus and for high stoma output with mucocutaneous separation. p=0.07. At our institution, patients treated with vedolizumab prior to surgery have a high prevalence of postoperative complications, notably mucocutaneous separation of the stoma. A prospective, multicenter study is needed to determine if these observed complications are attributable to vedolizumab. Level III. Copyright © 2018 Elsevier Inc. All rights reserved.

The postoperative complication is one of an indicator of poor prognosis in patients with several gastroenterological cancers after curative operations. We, herein, examined prognostic impacts of postoperative complications in patients with intrahepatic cholangiocarcinoma after curative operations. We retrospectively analyzed 60 patients with intrahepatic cholangiocarcinoma who underwent primary curative operations from June 2002 to February 2016. Prognostic impacts of postoperative complications were analyzed using log-rank test and Cox proportional hazard model. Postoperative complications (Clavien-Dindo classification grade 3 or more) occurred in 13 patients (21.7%). Overall survival of patients without postoperative complications was significantly better than that of patients with postoperative complications (p = 0.025). Postoperative complications are independent prognostic factor of overall survival (hazard ratio 3.02; p = 0.030). In addition, bile duct resection and reconstruction (Odds ratio 59.1; p = 0.002) and hepatitis C virus antibody positive (Odds ratio 7.14; p= 0.022), and lymph node dissection (Odds ratio 6.28; p = 0.040) were independent predictors of postoperative complications. Postoperative complications may be an independent predictor of poorer survival in patients with intrahepatic cholangiocarcinoma after curative operations. Lymph node dissection and bile duct resection and reconstruction were risk factors for postoperative complications, therefore we should pay attentions to perform lymph node dissections, bile duct resection and reconstruction in patients with intrahepatic cholangiocarcinoma.

This study investigated the impact of early enteral nutrition (EEN) on the clinical outcomes of gastric cancer patients after radical gastrectomy. Four hundred gastric cancer patients undergoing radical gastrectomy of any extend with D2 nodal dissection were randomly divided into an experimental and a control group with 200 cases in each group. Patients in the control group received postoperative parenteral nutrition (PN), while patients in the experimental group received postoperative EEN. After treatment, the clinical outcomes, postoperative immune function, and nutritional status of the two groups were evaluated. The postoperative fever time, intestinal function recovery time, anal exhaust time, and the length of hospital stay for patients in the experimental group were significantly shorter than those of the control group. We did not find significant differences in anastomotic leak, postoperative ileus and regurgitation between the two groups. The activities of multiple immune cell types, including CD3⁺, CD4⁺, CD4⁺/CD8⁺, and natural killer (NK) cells, were significantly lower in both groups on postoperative day 1 when compared with the preoperative levels (p<0.05). The level of CD8⁺ was not significantly different between the two groups (p>0.05). After treatment, levels of CD3⁺, CD4⁺, CD4⁺/CD8⁺, and NK cells in the experimental group patients were 35.6 ± 4.2, 42.2 ± 3.0, 1.7 ± 0.3, and 27.3 ± 5.3%, respectively, on postoperative day 7, which were similar to the preoperative levels. The immune cell levels from the control group patients remained significantly lower when compared with preoperative values; in addition, these values were also significantly lower when compared with the EEN patients (p<0.05) CONCLUSION: For gastric cancer patients undergoing radical gastrectomy, the clinical outcome, immune function and nutritional status after EEN were significantly improved. These data suggest the widespread use of EEN in clinical practice.

Gallstone ileus is a non-strangulated mechanical obstruction of the small bowel or colon as a result of the passage of gallstones through a biliary enteric fistula. It is a rare complication of cholelithiasis, affects patients over 65 years, and the disease occurs predominantly in females. Preoperative diagnosis is difficult due to the lack of specific signs and symptoms in elderly patients with multiple comorbidities. A 93-year-old female presenting with a one-week history of upper gastrointestinal bleeding, electrolyte imbalance and community- acquired pneumonia pneumonia. During her prolonged hospital stay she presented an intestinal obstruction. The diagnosis of gallstone ileus was made by CT scan. Despite surgical treatment, she died due to late diagnosis. Gallstone ileus is a rare pathology, difficulty in diagnosis prolongs hospital stay, which directly influences mortality. Copyright © 2016 Academia Mexicana de Cirugía A.C.

Old age is regarded as the risk factor of major abdominal surgery due to the lack of functional reserve and the increased presence of comorbidities. This study aimed to evaluate the impact of old age on the surgical outcomes of totally laparoscopic gastrectomy for gastric cancer. This study enrolled 389 gastric cancer patients who underwent totally laparoscopic gastrectomy at Hanyang University Guri Hospital and ASAN Medical Center. The patients were classified into two groups according to age as those older than 70 years and those younger than 70 years. Early surgical outcomes such as operation time, postoperative complications, time to first flatus, days until soft diet began, and hospital stay were evaluated. No patient was converted to open surgery. The two groups differed significantly in terms of overall postoperative complication rate, time to first flatus, days until soft diet began, and hospital stay. The patients who underwent Roux-en-Y gastrojejunostomy differed in incidence of postoperative ileus but not in severe postoperative complication rate. The results of this study demonstrated that old age can have an effect on the surgical outcomes of totally laparoscopic gastrectomy. This study especially showed that elderly patients are affected by the return of bowel movement after totally laparoscopic gastrectomy. On the other hand, however, it is presumed that old age has not had a serious impact on surgical outcomes in totally laparoscopic gastrectomy because no difference in the severe postoperative complication rate was observed.

This study aims to assess the impact of postoperative intravenous (IV) acetaminophen on opioid requirements and pain scores in patients following gynecologic procedures. A retrospective cohort study of patients undergoing gynecologic procedures was conducted to assess the impact of adding scheduled IV acetaminophen to postoperative analgesic regimens. The control group consisted of patients admitted prior to formulary addition of IV acetaminophen; the study group consisted of patients admitted after formulary addition of IV acetaminophen who received scheduled IV acetaminophen for at least the first 24 hours postoperatively. Opioid requirements 0 to 24 hours postoperatively served as the primary end point. Secondary end points included average pain score, cumulative acetaminophen dose, nonopioid analgesic requirements, and rate of adverse events 0 to 24 hours postoperatively. One hundred and thirty-seven patients who underwent a gynecologic procedure from January 2009 to April 2013 were included in this study. Baseline characteristics were similar between the groups. In the first 24 hours postoperatively, there was no difference in opioid requirements between the groups (21 mg [interquartile range, IQR, 15-39.8 mg] vs 32.6 mg [IQR, 16.75-41 mg], P = 0.150). The average pain score and incidence of adverse events did not differ between the 2 groups. Postoperative administration of IV acetaminophen did not provide a significant opioid-sparing effect in patients undergoing gynecologic procedures. © The Author(s) 2015.

Meconium ileus, intestinal obstruction in the newborn, is caused in most cases by CFTR mutations modulated by yet-unidentified modifier genes. We now show that in two unrelated consanguineous Bedouin kindreds, an autosomal-recessive phenotype of meconium ileus that is not associated with cystic fibrosis (CF) is caused by different homozygous mutations in GUCY2C, leading to a dramatic reduction or fully abrogating the enzymatic activity of the encoded guanlyl cyclase 2C. GUCY2C is a transmembrane receptor whose extracellular domain is activated by either the endogenous ligands, guanylin and related peptide uroguanylin, or by an external ligand, Escherichia coli (E. coli) heat-stable enterotoxin STa. GUCY2C is expressed in the human intestine, and the encoded protein activates the CFTR protein through local generation of cGMP. Thus, GUCY2C is a likely candidate modifier of the meconium ileus phenotype in CF. Because GUCY2C heterozygous and homozygous mutant mice are resistant to E. coli STa enterotoxin-induced diarrhea, it is plausible that GUCY2C mutations in the desert-dwelling Bedouin kindred are of selective advantage.

Background Postoperative (PO) pain interferes with the recovery and mobilization of the surgical patients. The impact of the educational status has not been studied adequately up to now. Methods This prospective study involved 400 consecutive general surgery patients. Various factors known to be associated with the perception of pain including the educational status were recorded as was the preoperative and postoperative pain and the analgesia requirements for the 1st PO week. Based on the educational status, we classified the patients in 3 groups and we compared these groups for the main outcomes: i.e. PO pain and PO analgesia. Results There were 145 patients of lower education (junior school), 150 patients of high education (high school) and 101 of higher education (university). Patients of lower education were found to experience more pain than patients of higher education in all postoperative days (from the 2nd to the 6th). No difference was identified in the type and quantity of the analgesia used. The subgroup analysis showed that patients with depression and young patients (< 40 years) had the maximum effect. Conclusions The educational status may be a significant predictor of postoperative pain due to various reasons, including the poor understanding of the preoperative information, the level of anxiety and depression caused by that and the suboptimal request and use of analgesia. Younger patients (< 40), and patients with subclinical depression are mostly affected while there is no impact on patients over 60 years old. PMID:26495081

Encapsulating peritoneal sclerosis is a rare complication of long-term peritoneal dialysis ranging from moderate inflammation of peritoneal structures to severe sclerosing peritonitis and encapsulating peritoneal sclerosis. Complicated it, ileus may occur during or after peritoneal dialysis treatment or after kidney transplant. We sought to evaluate 3 posttransplant encapsulating peritoneal sclerosis through clinical presentation, radiologic findings, and outcomes. We analyzed 3 renal transplant patients with symptoms of encapsulating peritoneal sclerosis admitted posttransplant to our hospital with ileus between 2012 and 2013. Conservative treatment was applied to the patients whenever necessary to avoid surgery. One patient improved with medical therapy. Surgical treatment was delayed and we decided it as a last resort, in 2 cases with no response to conservative treatment for a long time. Finally, patients with peritoneal dialysis history should be searched carefully before renal transplant for intermittent bowel obstruction story.

Postoperative hypocalcemia is a common complication of thyroidectomy. Magnesium is known to modulate serum calcium levels and hypomagnesemia may impede correction of hypocalcemia. The purpose of this study was to investigate whether hypomagnesemia after thyroidectomy has any impact on early hypocalcemia and/or permanent hypoparathyroidism. We conducted a retrospective review of prospectively maintained databases. Inclusion criteria were total or completion total thyroidectomy with postoperative magnesium levels available. The incidence of postoperative hypocalcemia was correlated with postoperative hypomagnesemia and other risk factors. Two hundred one cases were included. Twenty-six patients (13%) developed postoperative hypomagnesemia. Hypomagnesemia (p = .002), cancer diagnosis (p = .01), central neck dissection (p = .02), and inadvertent parathyroid resection (p = .02) were significantly associated with hypocalcemia. On multivariate analysis, only hypomagnesemia (p = .005) remained significant. Hypomagnesemia was also a significant predictor of permanent hypoparathyroidism (p = .0004). Hypomagnesemia is significantly associated with early hypocalcemia and permanent hypoparathyroidism after thyroidectomy. Magnesium levels should be closely monitored in patients with postthyroidectomy hypocalcemia. © 2015 Wiley Periodicals, Inc.

Complete resection of hepatoblastoma (HB) is a demanding procedure in advanced tumors. Perioperative complications are still common. The influence of complication rates on course of disease and survival of patients with HB has not been analyzed yet. Patients with high risk (HR) HB and standard-risk (SR) HB registered from 1999 to 2008 to the German prospective multicenter study HB99 were evaluated regarding perioperative complications, reasons (e.g., tumor size and vessel involvement) and impact on further treatment and overall survival (OS). Surgical data from 126 patients were available (47 HR-HB, 79 SR-HB). Postoperative complications occurred in 26 (21%) patients consisting of biliary leakage (n = 9), cholestasis (n = 5), deficit of liver perfusion (n = 5) and others (n = 7). Twenty of these 26 patients (77%) required a second operation. The rate of postoperative complications was higher in the HR-group (26%) compared to the SR-group (17%). Patients with vessel involvement had significantly more complications (17% vs. 54%, P = 0.01). Patients with PRETEXT I/II-tumors had the same rate of postoperative complications (19% vs. 20%) as patients with PRETEXT III/IV. Patients of HR-group with postoperative complications showed delayed start in adjuvant chemotherapy (>21 d) (75% vs. 25%, n.s.) combined with significant lower 5-year-OS (75% vs. 50%, P = 0.02). In multivariate analysis postoperative complications were an independent negative prognostic factor for HR-patients (HR 3.1, P = 0.04). Postoperative complications after HB resection are frequent and associated with worsened OS of patients with HR-HB. One possible reason is delay in postoperative chemotherapy. The approach to precarious liver resection should be carefully planned and executed by specialists. © 2014 Wiley Periodicals, Inc.

Gallstone ileus is a diagnosis of rarity, and a proximal site of obstruction in a young patient is even rare. Of the three cases in our experience, we found two cases of gallstone ileus (GSI) with typical epidemiology and presentation, one had combination of multiple rare associations. We report such a case, suspected to have gallstone ileus on ultrasound and confirmed diagnosis on computed tomography. Presence of biliary-enteric fistula, old age, and obstructive features, as in typical cases, was a bigger asset for diagnosis, but it was difficult to entertain diagnosis of GSI in young girl in absence of a demonstrable biliary-enteric fistula, with uncommon association of choledochal cyst and sickle cell disease. A very surprising finding, dilated major papilla, could however explain the pathogenesis which has also been reported in the past. Although differential opinions regarding management exist, we decided to follow two-stage surgery as our institute protocol. A minimal access approach has been immensely helpful in accurate diagnosis, and expedative management with early recovery has been proven in the past studies which we agreed with our experience.

Despite technical advances, bile leak remains a significant complication after hepatectomy. The current study uses a targeted multi-institutional dataset to characterize perioperative factors that are associated with bile leakage after hepatectomy to better understand the impact of bile leak on morbidity and mortality. Adult patients in the 2014-2015 ACS NSQIP targeted hepatectomy dataset were linked to the ACS NSQIP PUF dataset. Bivariable and multivariable regression analyses were used to assess the associations between clinical factors and post-hepatectomy bile leak. Of 6859 patients, 530 (7.7%) had a postoperative bile leak. Proportion of bile leaks was significantly greater in patients after major compared to minor hepatectomy (12.6 vs. 5.1%, p < 0.001). The proportion of patients with bile leak was significantly greater in patients after major hepatectomy who had concomitant enterohepatic reconstruction (31.8 vs. 10.1%, p < 0.001). Postoperative mortality was significantly greater in patients with bile leaks (6.0 vs. 1.7%, p < 0.001). After adjusting for significant covariates, bile leak was independently associated with increased risk of postoperative morbidity (OR = 4.55; 95% CI 3.72-5.56; p < 0.001). After adjusting for significant effects of postoperative complications, liver failure, and reoperation (all p<0.001), bile leak was not independently associated with increased risk of postoperative mortality (p = 0.262). Major hepatectomy and enterohepatic biliary reconstruction are associated with significantly greater rates of bile leak after liver resection. Bile leak is independently associated with significant postoperative morbidity. Mitigation of bile leak is critical in reducing morbidity and mortality after liver resection.

Arteriosclerosis is a disease effecting large elastic, elastic muscular and large muscular arteries. The primary pathological changes are found inside the arteries. Salient feature is atherosclerotic plaque. The main purpose of this paper is to determine whether early kinesitherapy with verticalization and mobilization can give better rehabilitation results with patients after lower extremities operation, in comparison to patients which were not mobilized early in this stage. In this paper we have analyzed two groups of 40 patients that were operatively treated for circulation obstruction to lower extremities. The first, tested group was treated with early kinesiotherapy with early verticalization and mobilization. The second, controlled group was treated with kinesitherapy in bed. All the patients were analyzed according to their gender, age, primary diagnosis, postoperative complications, as well as capabilities for everyday activities. For the evaluation of the everyday life activities we used the Barthel index at hospital admission and discharge. Both groups of patients were equable in gender and age. The most common age group within the tested groups was between 61-70 for males and 51-60 for woman.The most common type of obstruction in both groups was occlusion of femoral artery. The complications which occurred among the tested patients were thrombosis, ileus and contracture in 7.5% of cases, while 85% of patients did not have any complications. Within the controlled group, decubitus occurred in 7.5% of cases, as well as gangrene and ileus. Ulcus occurred in 5% of patients, thrombosis in 10%, and contracture in 4% of cases. 40% of patients in this group were without complications. Based on the results stated above we can conclude that early kinesitherapy with verticalization and mobilization of patients in postoperative phase after the treatment of lower extremities obstruction, have shown much better results in comparison to the patients which were only

While the prevalence of obesity in IBD patients is rapidly increasing, it is unclear if obesity impacts surgical outcomes in this population. We aim to investigate the effects of BMI on perioperative and postoperative outcomes in IBD patients by stratifying patients into BMI groups and comparing outcomes between these groups. This is a retrospective cohort study where IBD patients who underwent intestinal surgeries between the years of 2000 to 2014 were identified. The patients were divided into groups based on BMI: underweight (BMI <18.5), normal weight (BMI 18.5-24.9), overweight (BMI 25-29.9), and obese (BMI ≥30). Preoperative patient demographics, operative variables, and postoperative complications were collected and compared between BMI groups. A total of 391 surgeries were reviewed (34 underweight, 187 normal weight, 105 overweight, and 65 obese) from 325 patients. No differences were observed in preoperative patient demographics, type of IBD, preoperative steroid or biologic mediator use, or mean laboratory values. No differences were observed in percent operative procedures with anastomosis, surgeries converted to open, estimated blood loss, intraoperative complications, and median operative time. Thirty-day postoperative complication rates including total complications, wound infection, or anastomotic leak were similar between groups. There was a statistically significant increased postoperative bleeding risk (p = 0.029) in underweight patients. The relative percent for increased postoperative bleeding risk between BMI groups was as follows: 2.9% in underweight, zero in normal weight, 2.9% in overweight, and zero in obese. Obesity does not appear to impact intraoperative variables nor does obesity appear to worsen postoperative complication rates in IBD patients.

Effect of preoperative suggestion on postoperative gastrointestinal motility.

Autonomic behavior is subject to direct suggestion. We found that patients undergoing major operations benefit more from instruction than from information and reassurance. We compared the return of intestinal function after intra-abdominal operations in 2 groups of patients: the suggestion group received specific instructions for the early return of gastrointestinal motility, and the control group received an equal-length interview offering reassurance and nonspecific instructions. The suggestion group had a significantly shorter average time to the return of intestinal motility, 2.6 versus 4.1 days. Time to discharge was 6.5 versus 8.1 days. Covariates including duration of operation, amount of intraoperative bowel manipulation, and amount of postoperative narcotics were also examined using the statistical model analysis of covariance. An average savings of $1,200 per patient resulted from this simple 5-minute intervention. In summary, the use of specific physiologically active suggestions given preoperatively in a beleivable manner can reduce the morbidity associated with an intra-abdominal operation by reducing the duration of ileus.

Postoperative infectious complications increase disease recurrence in colorectal cancer patients. We herein investigated the impact of infectious complications on gastric cancer recurrence after curative surgery. In total, 502 patients who underwent R0 resection for gastric cancer were reviewed. Patients were classified into those with infectious complications (IC group) and those without infectious complications (NO group). The risk factors for recurrence-free survival (RFS) were identified. Infectious complications, which occurred in 52 patients (10.4%), included pneumonia, ileus with a systemic inflammatory reaction, anastomotic leakage, and intraperitoneal abscess. The overall 5-year RFS rate was 83% in the NO group and 58% in the IC group (p = 0.000). Multivariate analysis demonstrated that age, ASA score, stage, and infectious complications were significant predictors of RFS. Infectious complications were a risk factor for gastric cancer recurrence. To avoid causing infectious complications, the surgical procedure, surgical strategy, and perioperative care should be carefully planned.

Optimal nutrition is essential to the recovery of burned patients. The authors evaluated the efficacy of an aggressive nutrition delivery protocol. The following protocol was implemented: initiation of tube feeds within 4 hours, acceleration to goal rate within 8 hours, and tolerance of gastric residual volumes of 400 ml. Patients on the protocol formed the study group whereas patients admitted immediately before implementation served as controls for a study period of 7 days after admission. Outcome variables included ileus, prokinetic medication use, intensive care unit and overall length of stay, ventilator days and mortality. Variables were compared using bivariate analysis. The 42 study subjects and 34 controls were similar at baseline. Time to initiation was similar (6.8 vs 9.4 hours; P = .226), however, goal rate was achieved much sooner in the study group (11.2 vs 20.9 hours; P < .001). Number of hours spent at goal was different on days 1 and 2 (6.62 vs 2.74, P = .003 and 17.24 vs 13.18, P = .032) with no difference thereafter. Residual volumes in the study group were higher from day 2 onward, and remained increased throughout the study period (401 vs 234 ml average; P = .449). Clinical ileus was much more common in the study group (8 cases vs 1, P = .037). There was no difference in length of stay or mortality. The protocol was successfully implemented and resulted in early achievement of goal tube feed rates. However, this resulted in tube feed intolerance as manifested by more cases of clinical ileus.

Concentration of Potassium in Plasma, Erythrocytes, and Muscle Tissue in Cows with Decreased Feed Intake and Gastrointestinal Ileus.

Healthy cows consume large amounts of potassium and a sudden loss in appetite can lead to hypokalemia. The routine method to evaluate potassium homeostasis is the measurement of the extracellular potassium in plasma or serum, but this does not provide information about the intracellular potassium pool. To evaluate potassium homeostasis by comparing the extracellular and intracellular potassium concentration in cows with reduced feed intake and gastrointestinal ileus. Twenty cows 1-3 days postpartum (group 1) and 20 cows with gastrointestinal ileus (group 2). Observational cross-sectional study. Plasma potassium was measured by using an ion-sensitive electrode. Intracellular potassium was measured in erythrocytes and muscle tissue (muscle biopsy) by using inductively coupled plasma optical emission spectroscopy. Cows of group 1 did not have hypokalemia. Overall cows with gastrointestinal ileus were hypokalemic (mean ± SD, 2.9 mmol/L ± 0.78), but potassium concentration in erythrocytes and muscle tissue was not lower than in postpartum cows. Intracellular potassium in erythrocytes varied very widely; group 1: 3497-10735 mg/kg (5559 ± 2002 mg/kg), group 2: 4139-21678 mg/kg (7473 ± 4034 mg/kg). Potassium in muscle tissue did not differ between group 1 (3356 ± 735 mg/kg wet weight) and group 2 (3407 ± 1069 mg/kg wet weight). No association between extracellular and intracellular potassium concentrations was detected. That measurement of plasma potassium concentration is not sufficient to evaluate potassium metabolism of cows. Copyright © 2016 The Authors.

On one side amoxicillin (or clindamycin) was used (antibiotics group) from 1 h pre-operation to 3 d post-operation. On the other side, placebo was used (placebo group) the same time. Postoperative inflammatory complications including alveolar osteitis (AO), surgical site infection (SSI), pre-buccal site infection and anterior isthmus faucium space infection were monitored and recorded 2 d and 10 d after the surgery. The pain, swelling, and trismus were also recorded. All 96 patients completed the study. Two AO (2.1%), one SSI (1.0%) and seven other infections were observed in the treatment group. Also three AO (3.1%), one SSI (1.0%) and eleven other infections were observed in the placebo group. However, no statistically significant differences were found in the incidence of various postoperative inflammatory complications and reactions between the groups (P > 0.05). There was no significant difference on the postoperative reaction, except pain on 10 d. Patients who had inflammatory infection recovered well with symptomatic anti-infection treatment. The use of amoxicillin (or clindamycin) cannot effectively prevent and reduce the postoperative inflammatory complications after surgical extraction of the impacted mandibular third molar.

This study compared serotonin concentrations in platelet poor plasma (PPP) from healthy horses and horses with surgical small intestinal (SI) colic, and evaluated their association with postoperative ileus, strangulation and non-survival. Plasma samples (with EDTA) from 33 horses with surgical SI colic were collected at several pre- and post-operative time points. Serotonin concentrations were determined using liquid-chromatography tandem mass spectrometry. Results were compared with those for 24 healthy control animals. The serotonin concentrations in PPP were significantly lower (P < 0.01) in pre- and post-operative samples from surgical SI colic horses compared to controls. However, no association with postoperative ileus or non-survival could be demonstrated at any time point. In this clinical study, plasma serotonin was not a suitable prognostic factor in horses with SI surgical colic. PMID:25694668

The impact of obesity on surgical morbidity in adults with congenital heart disease is currently unknown. The aim of our study was to investigate the impact of obesity on postoperative outcomes in adults with congenital heart disease undergoing reoperation for pulmonary valve replacement. A retrospective analysis was performed assessing the influence of obesity on surgical outcomes. Obesity was defined as a body mass index ≥30 kg/m2. The mean body mass index of the cohort was 25.9 ± 6.9 kg/m2 . The cohort included 71 patients with 17 patients (24%) being obese. There was no postoperative mortality. Obese patients had a longer hospital length of stay (6.6 vs. 4.7 days; P < .001) and increased incidence of postoperative arrhythmias (29% vs. 5.6%; P = .003) compared with nonobese patients. Multivariable analysis performed using logistic regression with backwards elimination demonstrated obesity was independently associated with hospital length of stay >5 days (odds ratio [OR] = 5.2; 95% confidence interval [CI]: 1.5-18.2, P = .01) and with increased postoperative arrhythmias (OR = 4.2; 95% CI: 1.7-40, P < .01). Obesity is associated with increased morbidity in adults with congenital heart disease undergoing pulmonary valve replacement, including longer hospitalization and higher risk for postoperative arrhythmias. © 2015 Wiley Periodicals, Inc.

Compliance of postoperative instructions following the surgical extraction of impacted lower third molars: A randomized clinical trial

Objectives: The understanding and adherence to postoperative care instructions are factors that influence the recuperation process after any surgical procedure. The aim of this study was to determine the percentage of patients who strictly follow the postoperative instructions after the extraction of an impacted lower third molar in relation to sociocultural level, preoperative anxiety scores and how postoperative information is provided to the patient. Study Design: Patients were randomly assigned to one of three different test groups according to how the postoperative instructions were presented: verbal, written and a group that received additional information. Before surgery, patients were required to complete the Corah Dental Anxiety Scale and personal information (age, gender and educational level) was also collected. P<0.05 was considered significant. Patients were surveyed a week after surgery regarding their adherence to postoperative instructions. Results: 84 patients (45 women and 39 men with an average of 28.23 ± 7.41 years) completed the study. There were no statistically significant differences regarding adherence of postoperative care instructions depending on the manner of instruction presentation, preoperative anxiety level and sociocultural level (p> 0.05). Quitting smoking or drinking of alcoholic/carbonated beverages were the main influential factors for the lack of adherence to postoperative care instructions during the week after surgery. Conclusions: Presentation of postoperative instructions, preoperative anxiety scores and sociocultural level do not appear to be key factors that promote the adherence to postoperative instructions. Key words:Compliance, postoperative instructions, treatment, third molar. PMID:25475774

Rationale The current standard surgical treatment for the cervix and uterine cancer is the radical hysterectomy (lymphadenohysterocolpectomy). This has the risk of intraoperative accidents and postoperative associated morbidity. Objective The purpose of this article is the evaluation and quantification of the associated complications in comparison to the postoperative morbidity which resulted after different types of radical hysterectomy. Methods and results Patients were divided according to the type of surgery performed as follows: for cervical cancer – group A- 37 classic radical hysterectomies Class III Piver - Rutledge -Smith ( PRS ), group B -208 modified radical hysterectomies Class II PRS and for uterine cancer- group C -79 extended hysterectomies with pelvic lymphadenectomy from which 17 patients with paraaortic lymphnode biopsy . All patients performed preoperative radiotherapy and 88 of them associated radiosensitization. Discussion Early complications were intra-abdominal bleeding ( 2.7% Class III PRS vs 0.48% Class II PRS), supra-aponeurotic hematoma ( 5.4% III vs 2.4% II) , dynamic ileus (2.7% III vs 0.96% II) and uro - genital fistulas (5.4% III vs 0.96% II).The late complications were the bladder dysfunction (21.6% III vs 16.35% II) , lower limb lymphedema (13.5% III vs 11.5% II), urethral strictures (10.8% III vs 4.8% II) , incisional hernias ( 8.1% III vs 7.2% II), persistent pelvic pain (18.91% III vs 7.7% II), bowel obstruction (5.4% III vs 1.4% II) and deterioration of sexual function (83.3% III vs 53.8% II). PRS class II radical hysterectomy is associated with fewer complications than PRS class III radical hysterectomy , except for the complications of lymphadenectomy . A new method that might reduce these complications is a selective lymphadenectomy represented by sentinel node biopsy . In conclusion PRS class II radical hysterectomy associated with neoadjuvant radiotherapy is a therapeutic option for the incipient stages of cervical cancer

The purpose of this case-control study was to evaluate the impact of hybrid minimally invasive esophagectomy for cancer on surgical stress response and nutritional status. All 34 consecutive patients undergoing hybrid minimally invasive esophagectomy for cancer at our surgical unit between 2008 and 2013 were retrospectively compared with 34 patients undergoing esophagectomy with open gastric tubulization (open), matched for neoadjuvant therapy, pathological stage, gender and age. Demographic data, tumor features and postoperative course (including quality of life and systemic inflammatory and nutritional status) were compared. Postoperative course was similar in terms of complication rate. Length of stay in intensive care unit was shorter in patients undergoing hybrid minimally invasive esophagectomy (P = 0.002). In the first postoperative day, patients undergoing hybrid minimally invasive esophagectomy had lower C-reactive protein levels (P = 0.001) and white cell blood count (P = 0.05), and higher albumin serum level (P = 0.001). In this group, albumin remained higher also at third (P = 0.06) and seventh (P = 0.008) postoperative day, and C-reactive protein resulted lower at third post day (P = 0.04). Hybrid minimally invasive esophagectomy significantly improved the systemic inflammatory and catabolic response to surgical trauma, contributing to a shorter length of stay in intensive care unit. © 2015 International Society for Diseases of the Esophagus.

Sarcopenia has been proposed to be a prognostic factor of outcomes for various diseases but has not been applied to Crohn's disease (CD). We aimed to assess the impact of sarcopenia on postoperative outcomes after bowel resection in patients with CD. Abdominal computed tomography images within 30 days before bowel resection in 114 patients with CD between May 2011 and March 2014 were assessed for sarcopenia as well as visceral fat areas and subcutaneous fat areas. The impact of sarcopenia on postoperative outcomes was evaluated using univariate and multivariate analyses. Of 114 patients, 70 (61.4%) had sarcopenia. Patients with sarcopenia had a lower body mass index, lower preoperative levels of serum albumin, and more major complications (15.7% vs 2.3%, P = .027) compared with patients without sarcopenia. Moreover, predictors of major postoperative complications were sarcopenia (odds ratio [OR], 9.24; P = .04) and a decreased skeletal muscle index (1.11; P = .023). Preoperative enteral nutrition (OR, 0.13; P = .004) and preoperative serum albumin level >35 g/L (0.19; P = .017) were protective factors in multivariate analyses. The prevalence of sarcopenia is high in patients with CD requiring bowel resection. It significantly increases the risk of major postoperative complications and has clinical implications with respect to nutrition management before surgery for CD.

Third molar surgery is one of the most common surgical procedures performed in general dentistry. Post-operative variables such as pain, swelling and trismus are major concerns after impacted mandibular third molar surgery. Use of passive tube drain is supposed to help reduce these immediate post-operative sequelae. The current study was designed to compare the effect of tube drain on immediate post-operative sequelae following impacted mandibular third molar surgery. To compare the post-operative sequelae after surgical removal of impacted mandibular third molar surgery with or without tube drain. Thirty patients with bilateral impacted mandibular third molars were divided into two groups: Test (with tube drain) and control (without tube drain) group. In the test group, a tube drain was inserted through the releasing incision, and kept in place for three days. The control group was left without a tube drain. The post-operative variables like, pain, swelling, and trismus were calculated after 24 hours, 72 hours, 7 days, and 15 days in both the groups and analyzed statistically using chi-square and t-test analysis. The test group showed lesser swelling as compared to control group, with the swelling variable showing statistically significant difference at post-operative day 3 and 7 (p≤ 0.05) in both groups. There were no statistically significant differences in pain and trismus variables in both the groups. The use of tube drain helps to control swelling following impacted mandibular third molar surgery. However, it does not have much effect on pain or trismus.

Heme oxygenase (HO-1) protects against inflammation. In this study, we investigated the protective function of hemin-induced HO-1 against lipopolysaccharide (LPS)-induced ileus. Rats received LPS intraperitoneally 24 h after intraperitoneal hemin pretreatment or placebo. We also injected zinc protoporphyrin (ZnPP, 3rd group), an inhibitor of HO-1, intraperitoneally 2 h before LPS administration. To assess intestinal muscle function, we examined muscularis strip contractility in an organ bath and measured gastrointestinal transit in vivo. We investigated inflammation within the muscularis using polymerase chain reaction (interleukin [IL]-6, inducible nitric oxide synthase (iNOS), HO-1 and IL-10) 6 and 24 h after LPS. Hemin significantly improved in vitro intestinal muscularis contractility (P < 0.001). In addition, hemin prevented LPS-induced dysmotility in vivo (gastrointestinal transit, geometric center: 8.39 ± 0.33 versus 5.68 ± 0.44; P < 0.001). In Zinc protoporphyrin (ZnPP)-treated animals, both parameters were significantly decreased compared with the hemin group. Messenger RNA expression demonstrated a significant reduction in IL-6 (6 h, hemin: 127.6 ± 36.7 versus LPS: 14,431 ± 5407; 24 h: 1.58 ± 0.39 versus 11.15 ± 2.59; P < 0.01) and iNOS (6 h: 2516 ± 985 versus 50,771 ± 13,321; 24 h: 55.11 ± 10.55 versus 257.1 ± 43.18; P < 0.001) in hemin-treated animals. Anti-inflammatory HO-1 messenger RNA levels (6 h, hemin: 116.3 ± 18.55 versus LPS: 26.02 ± 3.64; 24 h: 18.46 ± 2.69 versus 2.80 ± 0.32; P < 0.001) were increased. There was no significant difference in IL-10 levels at 6 and 24 h. ZnPP reversed the anti-inflammatory hemin effects. Hemin induction of HO-1 diminishes LPS-induced sepsis. Heme oxygenase-1 has a central role in preventing sepsis-induced ileus. This benefit is reversed by HO-1 inhibition with ZnPP. Copyright © 2012 Elsevier Inc. All rights reserved.

In some studies, gum-chewing was demonstrated to have a beneficial effect on resumption of bowel function; however, other contradictory findings in other studies refute the effects of gum-chewing on peristaltic movements and digestive system stimulation. In addition, most previous studies were after colorectal or gynecology surgery, whereas few reports focused on the effect of gum-chewing after gastrectomy. The aim of this randomized controlled trial was to assess the effectiveness of gum-chewing on postoperative bowel function in patients who had undergone laparoscopic gastrectomy. From March 2014 to March 2016, 75 patients with gastric cancer received elective laparoscopic surgery in Shanghai Tongji hospital and were postoperatively randomly divided into 2 groups: 38 in a gum-chewing (Gum) group and 37 in a control (No gum) group. The patients in the Gum group chewed sugarless gum 3 times daily, each time for at least 15 minutes, until the day of postoperative exhaust defecation. The mean time to first flatus (83.4 ± 35.6 vs. 79.2 ± 24.2 hours; P = 0.554) and the mean time to first defecation (125.7 ± 41.2 vs. 115.4 ± 34.2 hours; P = 0.192) were no different between the no gum and Gum groups. There was also no significant difference in the incidence of postoperative ileus (P = 0.896) and postoperative hospital stay (P = 0.109) between the 2 groups. The postoperative pain score at 48 hours (P = 0.032) in the Gum group was significantly higher than in the no gum group. There was no significant difference between the 2 groups in regards to patient demographics, comorbidities, duration of surgery, complications, and nausea/vomiting score. Gum-chewing after laparoscopic gastrectomy did not hasten the return of gastrointestinal function. In addition, gum-chewing may increase patient pain on the second postoperative day.

The knowledge of the influence of anesthetic techniques in postoperative outcomes has opened a large field of research in recent years. In this second part, we review some of the major controversies arising from the literature on the impact of anesthetic techniques on postoperative outcomes in 6 areas: postoperative cognitive dysfunction, chronic postoperative pain, cancer recurrence, postoperative nausea/vomiting, surgical outcomes, and resources utilization. The development of protective and preventive anesthetic strategies against short and long-term postoperative complications will probably occupy an important role in our daily anesthetic practice. Dynamic postoperative pain control has been confirmed as one of the basic requirements of accelerated postoperative recovery programs ("fast-track surgery"), and it is also a preventive factor for development of chronic postoperative pain. The weight of anesthetic technique on postoperative immunosuppression is to be defined. The potential influence of anesthesia on cancer recurrence, is a highly controversial area of research. The classic pattern of perioperative fluid therapy may increase postoperative complications. On the other hand, the maintenance of normoglycemia and normothermia was associated with a decreased postoperative morbidity. The high volume of surgical procedures means that the adequacy of human, organizational and technological resources have a major impact on overall costs.

The impact of early enteral nutrition (EEN) on clinical outcomes of gastric cancer patients was investigated. Three hundred pa-tients undergoing gastric cancer surgery from July 2010 to May 2014 were randomly divided into experimental and control groups (n = 150/group). Experimental group patients received enteral nutrition in water during the early postoperative period. Control group patients received conventional perioperative treatment. Patients' clinical outcomes, post-operative immune function, and nutritional statuses were compared, which revealed that the postoperative fever duration (80.2 ± 6.0 vs 88.1 ± 8.1 h, P < 0.05), anal exhaust time (78.8 ± 9.3 vs 85.3 ± 8.4 h, P < 0.05), and length of hospitalization (7.73 ± 2.13 vs 9.77 ± 1.76 days, P < 0.01) differed significantly. Treatment costs in thousands of dol-lars were 31.24 ± 3.21 for the experimental group and 35.61 ± 2.32 for the control group; this difference was statistically significant (P < 0.01). The incidence of postoperative complications did not significantly differ between the experimental and control groups [14.0% (21/150) vs 17.3% (26/150), P > 0.05]. At postoperative days 3 and 7, the CD3(+), CD4(+), natural killer cell, albumin, and prealbumin levels and CD4(+)/CD8(+) ra-tio were significantly higher in the experimental group than the control group (all P < 0.05). CD8(+) cell counts were significantly lower in the experimental group than the control group (P < 0.05). Postsurgical oral EEN can improve nutritional status and immune function and promote early recovery of intestinal function in patients with gastric cancer.

Background Sarcopenia is a surrogate marker of patient frailty that estimates the physiologic reserve of an individual patient. We sought to investigate the impact of sarcopenia on short- and long-term outcomes in patients having undergone surgical intervention for primary hepatic malignancies. Methods Ninety-six patients who underwent hepatic resection or liver transplantation for HCC or ICC at the John Hopkins Hospital between 2000 and 2013 met inclusion criteria. Sarcopenia was assessed by the measurement of total psoas major volume (TPV) and total psoas area (TPA). The impact of sarcopenia on perioperative complications and survival was assessed. Results Mean age was 61.9 years and most patients were men (61.4 %). Mean adjusted TPV was lower in women (23.3 cm3/m) versus men (34.9 cm3/m) (P<0.01); 47 patients (48.9 %) had sarcopenia. The incidence of a postoperative complication was 40.4 % among patients with sarcopenia versus 18.4 % among patients who did not have sarcopenia (P=0.01). Of note, all Clavien grade ≥3 complications (n=11, 23.4 %) occurred in the sarcopenic group. On multivariable analysis, the presence of sarcopenia was an independent predictive factor of postoperative complications (OR=3.06). Sarcopenia was not associated with long-term survival (HR=1.23; P=0.51). Conclusions Sarcopenia, as assessed by TPV, was an independent factor predictive of postoperative complications following surgical intervention for primary hepatic malignancies. PMID:25389056

The objective of this study was to analyze the impact on overall survival (OS) from the addition of postoperative radiation with or without chemotherapy after esophagectomy, using a large, hospital-based dataset. Previous retrospective studies have suggested an OS advantage for postoperative chemoradiation over surgery alone, although prospective data are lacking. The National Cancer Data Base was queried to select patients diagnosed with stage pT3-4Nx-0M0 or pT1-4N1-3M0 esophageal carcinoma (squamous cell or adenocarcinoma) from 1998 to 2011 treated with definitive esophagectomy ± postoperative radiation and/or chemotherapy. OS was analyzed using the Kaplan-Meier method and compared using the log-rank test. Multivariate Cox regression analysis was used to identify covariates associated with OS. There were 4893 patients selected, of whom 1153 (23.6%) received postoperative radiation. Most patients receiving radiation also received sequential/concomitant chemotherapy (89.9%). For the entire cohort, postoperative radiation was associated with a statistically significant but modest absolute improvement in survival (hazard ratio 0.77; 95% CI, 0.71-0.83; P < 0.001). On subgroup analysis, postoperative radiation was associated with improved OS for patients with node-positive disease (3-yr OS 34.3 % vs 27.8%, P < 0.001) or positive margins (3-yr OS 36.4% vs 18.0%, P < 0.001). When chemotherapy usage was incorporated, sequential chemotherapy was associated with the best survival (P < 0.001). Multivariate analysis revealed that the addition of chemotherapy to radiation therapy, whether sequentially or concurrently, was a strong prognostic factor for OS. In this hospital-based study, the addition of postoperative chemoradiation (either sequentially or concomitantly) after esophagectomy was associated with improved OS for patients with node-positive disease or positive margins.

To evaluate the impact of glycemic control and nutritional status after total pancreatectomy (TP) on complications, tumor recurrence and overall survival. Retrospective records of 52 patients with pancreatic tumors who underwent TP were collected from 2007 to 2015. A series of clinical parameters collected before and after surgery, and during the follow-up were evaluated. The associations of glycemic control and nutritional status with complications, tumor recurrence and long-term survival were determined. Risk factors for postoperative glycemic control and nutritional status were identified. High early postoperative fasting blood glucose (FBG) levels (OR = 4.074, 95%CI: 1.188-13.965, P = 0.025) and low early postoperative prealbumin levels (OR = 3.816, 95%CI: 1.110-13.122, P = 0.034) were significantly associated with complications after TP. Postoperative HbA1c levels over 7% (HR = 2.655, 95%CI: 1.299-5.425, P = 0.007) were identified as one of the independent risk factors for tumor recurrence. Patients with postoperative HbA1c levels over 7% had much poorer overall survival than those with HbA1c levels less than 7% (9.3 mo vs 27.6 mo, HR = 3.212, 95%CI: 1.147-8.999, P = 0.026). Patients with long-term diabetes mellitus (HR = 15.019, 95%CI: 1.278-176.211, P = 0.031) and alcohol history (B = 1.985, SE = 0.860, P = 0.025) tended to have poor glycemic control and lower body mass index levels after TP, respectively. At least 3 mo are required after TP to adapt to diabetes and recover nutritional status. Glycemic control appears to have more influence over nutritional status on long-term outcomes after TP. Improvement in glycemic control and nutritional status after TP is important to prevent early complications and tumor recurrence, and improve survival.

The impact of age and oral calcium and vitamin D supplements on postoperative hypocalcemia after total thyroidectomy. A prospective study

PubMed Central

2013-01-01

Background Hypocalcemia caused by transient or definitive hypoparathyroidism is the most frequent complication after total thyroidectomy (TT). We aimed to compare the impact of age and the clinical usefulness of oral calcium and vitamin D supplements on postoperative hypocalcemia after TT, and to determine which risk factors are important for hypocalcemia incidence. Methods Two hundred consecutive patients treated by TT were included prospectively in the present study. All patients supplemented oral calcium and vitamin D in the post-operative time. The data concerning symptomatic and laboratoristichypocalcemia were collected. Patients were evaluated according to age, sex, postoperative serum calcium levels, and preoperative serum alkaline phosphatasis levels. Results Symptomatic hypocalcemia developed only in 19 patients (9.5%), whereas laboratory hypocalcemia developed in 36 patients (18%). The risk for postoperative hypocalcemia was increate 20-fold for patients older than 50 years. Conclusions Age is significantly associated with postoperative hypocalcemia. Implementing oral calcium and vitamin D after total thyroidectomy can reduce the incidence of hypocalcemia related to surgery. PMID:24267491

2012-02-01

It is commonly perceived that surgery in obese patients is associated with worse outcomes than in nonobese patients. Because of the increasing prevalence of obesity and colonic diseases in the world population, the impact of obesity on outcomes of laparoscopic colectomy remains an important subject. The aim of this review was to evaluate the feasibility and safety of laparoscopic colectomy for colorectal diseases in obese patients compared with nonobese patients. We conducted a comprehensive review for the years 1983-2010 to retrieve all relevant articles. A total of 33 studies were found to be eligible and included 3 matched case control studies and 1 review article. Obesity, often accompanied by preexisting comorbidities, was associated with longer operative times and higher rates of conversion to open procedures mainly because of the problem of exposure and difficulties in dissection. Although some studies showed obesity was associated with increased postoperative morbidity including cardiopulmonary and systemic complications, or ileus leading to longer hospital stay, there was no evidence about the negative impact of obesity on intraoperative blood loss, perioperative mortality, and reoperation rate. Whether obesity is a risk factor for wound infection after laparoscopic colectomy remains unclear. Though sometimes in obese patients, additional number of ports were necessary to successfully complete the procedure laparoscopically, obesity did not influence the number of dissected lymph nodes in cancer surgery. Lastly, the postoperative recovery of gastrointestinal function was similar between obese and nonobese patients. Laparoscopic colorectal surgery appears to be a safe and reasonable option in obese patients offering the benefits of a minimally invasive approach, with no evidence for compromise in treatment of disease.

Post-operative complications of various degrees of severity are commonly observed in third molar impaction surgery. For this reason, a surgical procedure that decreases the trauma of bone and soft tissues should be a priority for surgeons. In the present study, we compare the efficacy and the post-operative complications of patients to whom two different surgical techniques were applied for impacted lower third molar extraction. Patients of the first group underwent the classical bur technique, while patients of the second group underwent another technique, in which an elevator was placed on the buccal surface of the impacted molar in order to luxate the alveolar socket more easily. Comparing the two techniques, we observed a statistically significant decrease in the duration of the procedure and in the need for tooth sectioning when applying the second surgical technique, while the post-operative complications were similar in the two groups. We also found a statistically significant lower incidence of lingual nerve lesions and only a slightly higher frequency of sharp mandibular bone irregularities in the second group, which however was not statistically significant. The results of our study indicate that the surgical technique using an elevator on the buccal surface of the tooth seems to be a reliable method to extract impacted third molars safely, easily, quickly and with the minimum trauma to the surrounding tissues.

Most of the textbooks of anesthesia do not devote any chapter to anesthesia for abdominal surgery. Whereas the choice of anesthetics has minimal impact on postoperative outcome of the patient scheduled for these procedures global perioperative anesthetic management however affects postoperative recovery, convalescence, or even morbidity. This presentation highlights practical measures susceptible of reducing postoperative complications and of shortening patient convalescence.

The removal of wisdom teeth is often associated with severe postoperative edema and pain, and operation on the third molar can cause local inflammation that impairs lymph transport. The objective of the study was to assess the efficacy of manual lymph drainage (MLD) in reducing swelling following bilateral wisdom tooth removal. Ten consecutive patients with bilateral impacted wisdom teeth that required surgical removal were enrolled in the study. Each patient was postoperatively treated with MLD (after Vodder's method) on one side of the neck region with the untreated contralateral side as a control. Swelling was evaluated using a tape-measure placed in contact with the skin. The six landmarks of measurement included tragus-lip junction, tragus-pogonion, mandibular angle-external corner of eye, mandibular angle-ala nasi, mandibular angle-lip junction, and mandibular angle-median point of chin. Subjective assessment of MLD was conducted with self-evaluation using a visual analogue bar scale (VAS, range 0-100 mm). Of the 6 linear measurements, 4 lines (2, 4, 5, 6) showed a significant reduction of swelling on the side of MLD compared to the untreated side. Mean score of VAS of pretreatment condition was 35.5 +/- 20.60 mm that decreased to 22 +/- 19.32 mm measured after MLD (p=0.0295). This initial study demonstrates that MLD may promote an improvement of lymph circulation and work in an adjunctive role for reduction of postoperative swelling and pain following removal of impacted third molars.

Exercise in the preoperative period, or prehabilitation, continues to evolve as an important tool in optimising patients awaiting major intra-abdominal surgery. It has been shown to reduce rates of post-operative morbidity and length of hospital stay. The mechanism by which this is achieved remains poorly understood. Adaptations in mesenteric flow in response to exercise may play a role in improving post-operative recovery by reducing rates of ileus and anastomotic leak. To systematically review the existing literature to clarify the impact of exercise on mesenteric arterial blood flow using Doppler ultrasound. PubMed, EMBASE and the Cochrane library were systematically searched to identify clinical trials using Doppler ultrasound to investigate the effect of exercise on flow through the superior mesenteric artery (SMA). Data were extracted including participant characteristics, frequency, intensity, timing and type of exercise and the effect on SMA flow. The quality of each study was assessed using the Downs and Black checklist. Sixteen studies, comprising 305 participants in total, were included. Methodological quality was generally poor. Healthy volunteers were used in twelve studies. SMA flow was found to be reduced in response to exercise in twelve studies, increased in one and unchanged in two studies. Clinical heterogeneity precluded a meta-analysis. The weight of evidence suggests that superior mesenteric arterial flow is reduced immediately following exercise. Differences in frequency, intensity, timing and type of exercise make a consensus difficult. Further studies are warranted to provide a definitive understanding of the impact of exercise on mesenteric flow.

Retrospective case series. To elucidate the impact of postoperative occiput-C2 (O-C2) angle change on subaxial cervical alignment. In the case of occipito-upper cervical fixation surgery, it is recommended that the O-C2 angle should be set larger than the preoperative value postoperatively. The present study included 17 patients who underwent occipito-upper cervical spine (above C4) posterior fixation surgery for atlantoaxial subluxation of various etiologies. Plain lateral cervical radiographs in a neutral position at standing were obtained and the O-C2 angle and subaxial lordosis angle (the angle between the endplates of the lowest instrumented vertebra (LIV) and C7 vertebrae) were measured preoperatively and postoperatively soon after surgery and ambulation and at the final follow-up visit. There was a significant negative correlation between the average postoperative alteration of O-C2 angle (DO-C2) and the average postoperative alteration of subaxial lordosis angle (Dsubaxial lordosis angle) (r=-0.47, p=0.03). There was a negative correlation between DO-C2 and Dsubaxial lordosis angles. This suggests that decrease of mid-to lower-cervical lordosis acts as a compensatory mechanism for lordotic correction between the occiput and C2. In occipito-cervical fusion surgery, care must be taken to avoid excessive O-C2 angle correction because it might induce mid-to-lower cervical compensatory decrease of lordosis.

Effectiveness of green tea mouthwash in postoperative pain control following surgical removal of impacted third molars: double blind randomized clinical trial

PubMed Central

2013-01-01

Background Pain following surgical removal of impacted molars has remained an important concern among practitioners. Various protocols have been proposed to reduce postoperative pain. However, each one has special side effects and limitations. As green tea possesses anti-inflammatory and antibacterial properties, the aim of the current study was to evaluate the effectiveness of green tea mouthwash in controlling postoperative pain. Materials and methods In a study with split-mouth and double blind design, 44 patients in need of bilateral removal of impacted third molars underwent randomized surgical extraction; following one surgery patients rinsed with a green tea mouthwash from the first to seventh postoperative day and after other extraction rinsed with placebo mouthwash in the same duration. Both patients and surgeon were blinded to the type of mouthwash. The predictor variable was type of mouthwash and primary outcome variable was postoperative pain measured by visual analogue scale (VAS) during first week after surgery. In addition, number of analgesics patients used after surgery recorded. To measure the effect of green tea mouthwash, repeated measures test with confidence interval of 95% was performed. Results Total of 43 patients with mean age of 24 years underwent total of 86 surgeries. VAS value had no statistically difference prior rinsing among groups (P-value > 0.05). However, the mean value of VAS following rinsing with green tea was statistically lower than placebo in postoperative days of 3–7 (P-value < 0.05). In addition, while rinsing with green tea, patients took significantly lower number of analgesics after surgery (P-value < 0.05). No side effects reported. Conclusion Green tea mouthwash could be an appropriate and safe choice to control postoperative pain after third molar surgery. PMID:23866761

To identify the risk factors associated with development of postoperative elevation of creatine kinase (CK) and study its effect on renal function in patients who underwent complex multifocal partial nephrectomy (PN). Patients who underwent PN at National Cancer Institute between January 2007 and December 2012 were included in the study. Elevated serum CK was defined as >2000 U/L. Kidney function was assessed using serum creatinine and estimated glomerular filtration rate (eGFR). Changes were reported as percent change from preoperative values and compared using the Wilcoxon test. Regression analysis was performed to identify the predictors of elevation in CK and decline in eGFR. From 407 total cases, 207 had adequate CK data for analysis. Median number of tumors removed was 3 (1-70). Median peak CK was 1458 (82-36,788). Forty-two percent developed CK elevation >2000 U/L. Factors associated with postoperative elevation of CK > 2000 were young age (p = 0.009), high BMI (p = 0.003) and operating room time (p < 0.001). Although CK > 2000 was associated with significantly greater decline in eGFR (37.4 vs. 20.3 %, p < 0.001) in immediate postoperative period, this change largely resolved to a much less clinically relevant (9.2 vs 3.3 %, p = 0.040) change after 3 months. On multivariate analysis, postoperative elevation in CK was not found to be an independent factor determining renal function at 3 months. In our cohort, a significant proportion of patients developed CK elevations >2000 U/L. While patients with elevated CK had more decline in eGFR in immediate postoperative period, postoperative elevations of CK did not appear to impact overall long-term renal function in patients undergoing PN.

The meconium disease represents a problem of great impact over the vital prognosis of the newborn, the mortality of this disease being rated in various studies between 30 and 50%. The meconial disease that reunites the meconial ileus and the meconial peritonitis is often associated with cystic fibrosis a disease of general impact over the entire organism increasing the gravity and influencing the vital prognosis of these patients. The authors' purpose is to evaluate the results obtained after the treatment of the meconial disease in the Pediatric Surgery Clinic of the Emergency Hospital of Craiova over a period of 10 years. The study has been made on a number of 16 cases of meconial ileus, plug and peritonitis analising the difficulty of the diagnostic process, the preoperative care as well as the possibilities of surgical treatment. The surgical treatment is composed of multiple procedures including simple suture of the bowel defect and segmentary bowel resections with primary anastomosis and/or secondary anastomosis after ileostoma. The mortality on the studied cases was of 37.5% despite recent progresses achieved in postoperative care of these type of patients.

Recent studies have found vedolizumab to be an independent predictor of increased rates of postoperative complications and surgical site infections (SSIs) in adults with inflammatory bowel disease (IBD), but studies in the pediatric surgical population are lacking. We sought to determine the 30-day postoperative infectious complication rate among pediatric IBD patients who received vedolizumab within 12weeks of a major abdominal operation. A retrospective chart review was performed on pediatric IBD patients who underwent an abdominal operation between 5/20/2014 and 6/1/2017. The study cohort was comprised of pediatric patients (≤18years) who received vedolizumab within 12weeks prior to their abdominal operation. The control cohort was all patients operated on for IBD during the same time on anti-TNF therapy within 12weeks of their abdominal operation. Thirteen pediatric patients (5 female) received vedolizumab within 12weeks of an abdominal operation and 36 patients received anti TNF therapy (20 female). There were no differences in the vedolizumab and anti-TNF therapy with regard to sex, median age of diagnosis or operation, IBD type, body mass index (BMI), smoking status, diabetes mellitus (DM), preoperative serum laboratory values, steroid or immunomodulatory use. The number of biologics previously exposed to was significantly higher in the vedolizumab treated patients (p<0.0001). There were no significant differences in operative characteristics including laparoscopic versus open surgery, construction of an anastomosis, or diversion of an anastomosis. There were also no significant differences found in 30-day postoperative complications including nonsurgical site infections (SSIs), all SSIs, small bowel obstruction (SBO)/ileus, hospital readmission, or return to the operating room (ROR). There were four RORs in total: one in the vedolizumab group was for a missed enterotomy and stoma revision; three in the anti-TNF cohort were for ileostomy revisions. None of

Right ventricular (RV) dysfunction after pulmonary resection in the early postoperative period is documented by reduced RV ejection fraction and increased RV end-diastolic volume index. Supraventricular arrhythmia, particularly atrial fibrillation, is common after pulmonary resection. RV assessment can be done by non-invasive methods and/or invasive approaches such as right cardiac catheterization. Incorporation of a rapid response thermistor to pulmonary artery catheter permits continuous measurements of cardiac output, right ventricular ejection fraction, and right ventricular end-diastolic volume. It can also be used for right atrial and right ventricular pacing, and for measuring right-sided pressures, including pulmonary capillary wedge pressure. This study included 178 patients who underwent major pulmonary resections, 36 who underwent pneumonectomy assigned as group (I) and 142 who underwent lobectomy assigned as group (II). The study was conducted at the cardiothoracic surgery department of Benha University hospital in Egypt; patients enrolled were operated on from February 2012 to February 2016. A rapid response thermistor pulmonary artery catheter was inserted via the right internal jugular vein. Preoperatively the following was recorded: central venous pressure, mean pulmonary artery pressure, pulmonary capillary wedge pressure, cardiac output, right ventricular ejection fraction and volumes. The same parameters were collected in fixed time intervals after 3 hours, 6 hours, 12 hours, 24 hours, and 48 hours postoperatively. For group (I): There were no statistically significant changes between the preoperative and postoperative records in the central venous pressure and mean arterial pressure; there were no statistically significant changes in the preoperative and 12, 24, and 48 hour postoperative records for cardiac index; 3 and 6 hours postoperative showed significant changes. There were statistically significant changes between the preoperative and

Preoperative immobility in general surgery patients has been associated with an increased risk of postoperative complications. It is unknown if immobility affects bariatric surgery outcomes. The aim of this study was to determine the impact of immobility on 30-day postoperative bariatric surgery outcomes. This study took place at a university hospital in the United States. The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program 2015 data set was queried for primary minimally invasive bariatric procedures. Preoperative immobility was defined as limited ambulation most or all the time. Logistic regression analysis was performed to determine if immobile patients are at increased risk (odds ratio [OR]) for 30-day complications. There were 148,710 primary minimally invasive bariatric procedures in 2015. Immobile patients had an increased risk of mortality (OR 4.59, P<.001) and greater operative times, length of stay, reoperation rates, and readmissions. Immobile patients had a greater risk of multiple complications, including acute renal failure (OR 6.42, P<.001), pulmonary embolism (OR 2.44, P = .01), cardiac arrest (OR 2.81, P = .05), and septic shock (OR 2.78, P = .02). Regardless of procedure type, immobile patients had a higher incidence of perioperative morbidity compared with ambulatory patients. This study is the first to specifically assess the impact of immobility on 30-day bariatric surgery outcomes. Immobile patients have a significantly increased risk of morbidity and mortality. This study provides an opportunity for the development of multiple quality initiatives to improve the safety and perioperative complication profile for immobile patients undergoing bariatric surgery.

Gum chewing has been reported to enhance bowel motility and reduce postoperative ileus (POI). However, the efficacy remains imprecise for women following caesarean section. To summarise and evaluate the current evidence for postoperative gum chewing on the recovery of bowel function following caesarean section. We searched studies from the following electronic databases: PubMed, EMBASE, SCOPUS and Cochrane Library from inception to 30 May 2013. We included randomised controlled trials (RCTs) of women after caesarean section; these RCTs should compared gum chewing with no gum chewing and reported on at least one of the outcomes: time to flatus, time to bowel sound, time to passing stool and length of hospital stay (LOS). Study outcomes were presented as mean differences (for continuous data) with 95% confidence interval (95% CI). The risk of bias in the study results was assessed using the assessment tool from the Cochrane Handbook. Six RCTs including 939 women were included in our meta-analysis. The pooled results demonstrated that gum chewing is superior to no gum chewing with a reduction of 6.42 hours (95% CI -7.55 to -5.29) for time to first flatus, 3.62 hours (95% CI -6.41 to -0.83) for time to first bowel sound, 6.58 hours (95% CI -10.10 to -3.07) for time to first stool and 5.94 hours (95% CI -9.39 to -2.49) for LOS. In addition, no evidence emerged for any side effects caused by gum chewing. The current evidence suggests that gum chewing is associated with early recovery of bowel motility and shorter LOS for women after caesarean section. This safe and inexpensive intervention should be included in routine postoperative care following a caesarean section. © 2014 Royal College of Obstetricians and Gynaecologists.

Impact of Operative and Postoperative Factors on Neurodevelopmental Outcomes After Cardiac Operations.

PubMed

2016-09-01

Neurodevelopmental disability is common after operations for congenital heart defects. We previously showed that patient and preoperative factors, center, and calendar year of birth explained less than 30% of the variance for the Psychomotor Development Index (PDI) and the Mental Development Index (MDI) of the Bayley Scales of Infant Development-Second Edition. Here we investigate how much additional variance in PDI and MDI is contributed by operative variables and postoperative events. We analyzed neurodevelopmental outcomes after operations with cardiopulmonary bypass at age 9 months or younger between 1996 and 2009. We used linear regression to investigate the effect of operative factors (age, weight, and cardiopulmonary bypass variables) and postoperative events on neurodevelopmental outcomes, adjusting for center, type of congenital heart defect, year of birth, and preoperative factors. We analyzed 1,770 children from 22 institutions with neurodevelopmental testing at age 13.3 months (range, 6 to 30 months). Among operative factors, longer total support time was associated with lower PDI and MDI (p < 0.05). When postoperative events were added, use of either extracorporeal membrane oxygenation or ventricular assist device support, and longer postoperative length of stay were associated with lower PDI and MDI (p < 0.05). Longer total support time was not a significant predictor in these models. After adjusting for patient, preoperative, intraoperative, and postoperative factors, measured intraoperative and postoperative factors accounted for 5% of the variances in PDI and MDI. Operative factors may be less important than innate patient and preoperative factors and postoperative events in predicting early neurodevelopmental outcomes after cardiac operations in infants. Neurodevelopmental outcomes improved over calendar time when adjusted for patient and medical variables. Copyright © 2016 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights

The aim of this prospective randomised study was to assess the effects of tube drainage on postoperative discomfort after the extraction of impacted mandibular third molars. We studied 40 patients (11 men and 29 women) 18 years or older (mean (SD) 21 (3), range 18-29) who required extraction of mandibular third molars. We used a randomised crossover design by which if a drain was inserted on one side, then the other side was managed without a drain on a later occasion. Pain, swelling, and mouth opening were evaluated after 48 h and 7 days postoperatively in both groups. Facial swelling (p=0.001), pain p=0.001), and trismus (p=0.001) were significantly less common in the drained group compared with those not drained. We conclude that the use a tube drain is of benefit in minimising postoperative swelling, pain, and trismus after extraction of mandibular third molars.

Colectomy is one of the most common major abdominal procedures performed in the USA. A better understanding of risk factors and the effect of operative approach on adverse postoperative outcomes may significantly improve quality of care. Adult patients with a primary diagnosis of colon cancer undergoing colectomy were selected from the National Surgical Quality Improvement Program 2013-2015 targeted colectomy database. Patients were stratified into five groups based on specific operative approach. Univariate and multivariate analyses were used to compare the five groups and identify risk factors for 30-day anastomotic leak, readmission, and mortality. In total, 25,097 patients were included in the study, with a 3.32% anastomotic leak rate, 1.20% mortality rate, and 9.57% readmission rate. After adjusting for other factors, open surgery and conversion to open significantly increased the odds for leak, mortality, and readmission compared to laparoscopy. Additionally, smoking and chemotherapy increased the risk for leak and readmission, while total resection was associated with increased mortality and leak. Operative approach and several other potentially modifiable perioperative factors have a significant impact on risk for adverse postoperative outcomes following colectomy. To improve quality of care for these patients, efforts should be made to identify and minimize the influence of such risk factors.

The primary driver of length of stay after bowel surgery, particularly colorectal surgery, is the time to return of gastrointestinal (GI) function. Traditionally, delayed GI recovery was thought to be a routine and unavoidable consequence of surgery, but this has been shown to be false in the modern era owing to the proliferation of enhanced recovery protocols. However, impaired GI function is still common after colorectal surgery, and the current literature is ambiguous with regard to the definition of postoperative GI dysfunction (POGD), or what is typically referred to as ileus. This persistent ambiguity has impeded the ability to ascertain the true incidence of the condition and study it properly within a research setting. Furthermore, a rational and standardized approach to prevention and treatment of POGD is needed. The second Perioperative Quality Initiative brought together a group of international experts to review the published literature and provide consensus recommendations on this important topic with the goal to (1) develop a rational definition for POGD that can serve as a framework for clinical and research efforts; (2) critically review the evidence behind current prevention strategies and provide consensus recommendations; and (3) develop rational treatment strategies that take into account the wide spectrum of impaired GI function in the postoperative period.

Postoperative ileus occurs in different degrees, in the majority of patients undergoing radical cystectomy, which may increase the length of hospital stay. The use of chewing gum has demonstrated its effectiveness in reducing time-to-bowel function and the length of hospital stay in several surgical procedures. To evaluate the benefit of post-operative chewing gum use in patients undergoing radical cystectomy through a systematic review of the literature and meta-analysis. We performed a literature search of MedLine, Scopus, CochraneLibrary and ClinicalTrials.Gov in March 2017 according to the Cochrane Handbook and the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes. The studies were evaluated according to the "Oxford Center for Evidence-Based Medicine" criteria. The outcome measures evaluated were time-to-flatus, time-to-defecation, length of the hospital stay, and the rates of general and gastrointestinal postoperative complications. Continuous and dichotomous variables were compared respectively using weighted means differences and odds ratios with 95 % confidence intervals. The presence of publication bias was examined by funnel plots. Three studies (including 274 patients in total) met the inclusion criteria. The pooled results demonstrated a 11.82hour reduction in time-to-flatus (95 % CI : -15.43, -8.22h, P <0.00001), and 19.57hours in time-to-defecation (95 % CI : -29.33, -9.81h, P <0.0001), and a decreasing trend of 2.85 days in the length of the hospital stay (95 % CI : -6.13, -0.43, P=0.09), by the use of chewing gum. There was no significant difference between the "chewing gum" and "control" groups in terms of general and gastrointestinal complications (Peto Odds ratio 1.04 [0.60, 1.79], 95 % CI, P=0.89 and Peto Odds ratio 0.65 [0.26, 1.61], 95 % CI, P=0.35 respectively). Chewing gum may be recommended postoperatively in patients undergoing radical cystectomy to improve time-to-bowel function. Copyright © 2017 Elsevier

Assessment of impact of late postoperative physical functional disabilities on quality of life in breast cancer survivors.

Breast cancer is the second most common malignancy among women. Surgical and supplemental (or adjuvant) therapies to combat the disease may implicate physical functional consequences for the ipsilateral upper extremity. These dysfunctions may persist for many years and have repercussions on the performance of daily living activities. The aim of this study was to assess the impact of physical functional disabilities on quality of life in women after breast cancer surgery. Eighty-two women in the postoperative period of conservative surgery for breast cancer participated in the study. Axillary lymph node dissection was performed in all patients and mean time since surgery was 5.78 (± 4.60) years. The women responded to a questionnaire to assess quality of life (FACT-B) and to another to assess functional capacity (QuickDASH). They were then referred to physical therapy examination to measure shoulder range of motion (flexion, abduction and external rotation) and arm volume. Range of motion in the ipsilateral shoulder was limited: shoulder flexion range of motion reached a mean value of 155.44º (± 28.31), mean abduction was 149.05º (± 29.51), and mean external shoulder rotation was 58.44º (± 29.17). These limitations had a negative impact on functional capacity and global quality of life. Lymphedema was present in 28.04% of women assessed and did not impair quality of life or functional capacity. Physical functional disabilities were present in the late postoperative period of breast cancer survivors and limited shoulder range of motion negatively influenced their functional capacity and quality of life. The presence of lymphedema did not impair functional capacity or quality of life in the postoperative period.

Acupuncture is a widely serviced complementary medicine. Although acupuncture is suggested for managing postoperative ileus and pain, supporting evidence is weak. The AcuLap trial is designed to provide high-level evidence regarding whether or not electroacupuncture is effective in promoting gastrointestinal motility and controlling pain after laparoscopic surgery. This study is a prospective randomized controlled trial with a three-arm, parallel-group structure evaluating the efficacy of electroacupuncture for gastrointestinal motility and postoperative pain after laparoscopic appendectomy. Patients with appendicitis undergoing laparoscopic surgery are included and randomized into three groups: 1) electroacupuncture group, 2) sham acupuncture group, and 3) control group. Patients receive 1) acupuncture with electrostimulation or 2) fake electroacupuncture with sham device twice a day or 3) no acupuncture after laparoscopic appendectomy. The primary outcome is time to first passing flatus after operation. Secondary outcomes include postoperative pain, analgesics, nausea/vomiting, bowel motility, time to tolerable diet, complications, hospital stay, readmission rates, time to recovery, quality of life, medical costs, and protocol failure rate. Patients and hospital staff (physicians and nurses) are blinded to which group the patient is assigned, electroacupuncture or sham acupuncture. Data analysis personnel are blinded to group assignment among all three groups. Estimated sample size to detect a minimum difference of time to first flatus with 80 % power, 5 % significance, and 10 % drop rate is 29 × 3 groups = 87 patients. Analysis will be performed according to the intention-to-treat principle. The AcuLap trial will provide evidence on the merits and/or demerits of electroacupuncture for bowel motility recovery and pain relief after laparoscopic appendectomy.

The relief of post-cesarean delivery pain is important. Good pain relief improves mobility and reduces the risk of thromboembolic disease, which may have been increased during pregnancy. Pain may impair the mother's ability to optimally care for her infant in the immediate postpartum period and may adversely affect early interactions between mother and infant. It is necessary, therefore that pain relief be safe and effective and results in no adverse neonatal effects during breast-feeding. Music may be considered as a potential method of post cesarean pain therapy due to its noninvasiveness and lack of side effects. In this study we evaluated the effect of intraoperative music under general anesthesia for reducing the postoperative morphine requirements after cesarean section. In a double blind placebo-controlled trial, 100 women (ASA I) scheduled for elective cesarean section under general anesthesia, were randomly allocated into two groups of fifty. After standardization of anesthesia, patients in the music group were exposed to a compact disk of Spanish guitar after induction of anesthesia up to the time of wound dressing. In the control group patients were exposed to white music. Post operative pain and anxiety were evaluated by visual analog scale (VAS) up to six hours after discharge from PACU. Morphine was given intravenously for reducing pain to VAS < or = 3 postoperatively. There was not statistically significant difference in VAS for pain between two groups up to six hours postoperatively (P>0.05). In addition, morphine requirements were not different between two groups at different time intervals up to six hours postoperatively (P>0.05). There were not statistically significant difference between two groups regarding postoperative anxiety score and vomiting frequency (P>0.05). As per conditions of this study, intraoperative Spanish music was not effective in reducing postoperative pain after cesarean section. In addition postoperative morphine

Our objective was to evaluate the significance of the R.E.N.A.L. nephrometry score (RNS)--developed to quantitatively evaluate the complexity of renal tumors in a reproducible manner--in perioperative and renal functional outcomes following robot-assisted partial nephrectomy (RAPN). This study assessed 48 consecutive patients with renal tumors who underwent RAPN. Preoperative RNS for each patient was calculated, and its impact on several parameters associated with perioperative outcomes, including postoperative renal function, was investigated with Spearman's rank correlation test. Mean RNS in the 48 patients was 6.8; of these 48 patients, 21 (43.7%), 24 (50.0%), and three (6.3%) were classified into low-, moderate-, and high-complexity groups, respectively. The RNS was significantly correlated with resected tumor weight and postoperative changes in estimated glomerular filtration rate (eGFR) at both 1 and 4 weeks--but not age, body mass index (BMI), preoperative eGFR, operative time, warm ischemia time, estimated blood loss, postoperative complications, or eGFR-- after RAPN. No component of the RNS (R: radius; E: exophytic/endophytic properties; N: nearness of tumor to the collecting system or sinus; A: anterior/posterior; L: location relative to polar lines) alone had a significant impact on postoperative changes in eGFR at 1 and 4 weeks, whereas resected tumor weight was significantly associated with the R and E subcategories. Measurement of total RNS is useful for predicting renal functional outcomes early after RAPN.

Surgical handling of the bowel evokes degranulation of peritoneal mast cells (PMC). Nonetheless, role of PMCs in postoperative ileus (POI) is somewhat controversial. We aimed to investigate if intestinal manipulation elicits changes in afferent mediators related to MC activation and alteration of gastrointestinal (GI) motility. Postoperative ileus was induced by intestinal manipulation in Sprague-Dawley rats. Additionally, compound 48/80 (C48/80) and ketotifen were used to modulate MC activity. Rat mast cell protease 6 (RMCP-6, ELISA) release was determined in peritoneal lavage 20 min after intestinal manipulation. At 24 h, GI transit was determined. Gene expression of calcitonin gene-related peptide (CGRP), protease-activated receptor-2 (PAR-2), nerve growth factor (NGF), and TrkA receptor was determined (PCR) in dorsal root ganglia (DRG). Ileal wall inflammation was assessed by myeloperoxidase (MPO) activity, interleukin-6 expression (IL-6). Intestinal manipulation and exposure to C48/80-induced degranulation of PMCs delayed GI transit and up-regulated IL-6 and MPO activity. Intestinal manipulation, but not C48/80, up-regulated CGRP, PAR-2, and NGF/TrkA in DRGs. Ketotifen only improved gastric emptying and fecal output. Up-regulation of CGRP and TrkA expression in DRG was not prevented by ketotifen. Postoperative ileus is accompanied by activation of CGRP, NGF-TrkA, and PAR-2 in DRGs. Our results suggest that these mediators could be a target in further POI studies in order to find new therapeutic targets for this medical condition. © 2016 John Wiley & Sons Ltd.

Head and neck mucosal melanoma (HNMM) is a rare type of malignant tumor that frequently exhibits postoperative recurrence and distant metastasis. Many clinicians administer postoperative adjuvant radiotherapy to improve patient prognosis and enhance quality of life; however, the effects of this treatment remain controversial. Therefore, in this study, a meta-analysis was performed to evaluate the practical value of postoperative adjuvant radiotherapy for head and neck mucosal melanoma. Articles in the PubMed, MEDLINE, Cochrane Library, Web of Science and EMBASE databases were systematically retrieved. Analyses were conducted to compare the impact of treatments involving postoperative radiotherapy with treatments entailing surgery alone on patient overall survival time, local recurrence and distant metastasis. The hazard ratio (HR) was used to evaluate the time-to-event data employing RevMan version 5.2 and Stata/SE version 13.0 software according to the principles specified for systematic reviews of interventions in the Cochrane handbook. Twelve cohort studies involving 1593 patients satisfied the desired conditions. In comparing surgery alone with postoperative radiotherapy, there was no significant difference regarding a decrease in the death risk in HNMM patients (HR, 1.07; 95 % CI, 0.95-1.2; p = 0.903; low heterogeneity, I(2) = 0); this was also the case for sinonasal melanoma after subgroup meta-analysis (HR, 1.04; 95 % CI, 0.8-1.36; p = 0.983; low heterogeneity, I(2) = 0 %). A sensitivity analysis and subgroup meta-analysis showed that disease progression was the main source of the instability in the results. Surgery combined with postoperative radiotherapy reduced the risk of local recurrence (HR, 0.51; 95 % CI, 0.35-0.76; p = 0.155) but did not reduce the risk of distant metastasis (HR, 2.26; 95 % CI, 1.01-5.05; p = 0.006). This study demonstrated that for HNMM patients surgery is recommended if indicated, and surgery combined with

The aim of this study was to evaluate the effectiveness of submucosal application of tramadol, for acute postoperative facial pain, following the extraction of impacted third molar teeth. This prospective, double-blind, randomised placebo-controlled study included 60 ASA I-II patients undergoing impacted third molar surgery under local anaesthesia. Following the surgical procedure, patients were randomly divided into two groups; group T (1 mg/kg tramadol) and group S (2-mL saline). Treatments were applied submucosally after surgery. Pain after extraction was evaluated using a visual analogue scale (VAS) 0.5, 1, 2, 4, 6, 12, 24, and 48 h postoperatively. The time at which the first analgesic drug was taken, the total analgesic dose used, and adverse tissue reactions were also evaluated. In group T, postoperative VAS scores were significantly lower compared to that in group S (p < 0.05). This study demonstrated that post-operative submucosal application of tramadol is an effective method for reducing acute post-operative facial pain after impacted third molar surgery.

The aim of this study was to determine the impact of hypovitaminosis D on Gastric Bypass outcomes. We retrospectively reviewed all patients who underwent primary intention Gastric Bypass in our center between January 2012 and December 2013. Postoperative complications, 1 and 2-year excess weight loss were compared between patients with and without hypovitaminosis D. Among 258 patients who met inclusion criteria, 56 (21.7%) presented with vitamin D deficiency. Mean age was 41.73 ± 12.95 years. Mean BMI was 40.90 kg/m 2 (34-58 kg/m 2 ). No statistically significant difference in postoperative complication rate was found between patients with and without hypovitaminosis D. Mean 1-year excess weight loss was 75.24%. In patients with vitamin D deficiency mean 1-year excess weight loss was 71.90 versus 76.15% in patients with optimal serum vitamin D level (p = 0.17). No significant difference was found after a 2-year follow-up. In patients presenting with vitamin D insufficiency, 1-year excess weight loss was 75.64 versus 79.34% in patients with optimal serum vitamin D level (p = 0.53). After a 2-year follow-up, there was a significant difference between patients presenting with and without vitamin D insufficiency (79.45 versus 91.71%; p = 0.01) and between patients presenting with and without hypovitaminosis D (80.50 versus 91.71%; p = 0.01). In our study, hypovitaminosis D seemed to have a negative impact on long term excess weight loss, but not on short-term outcome or postoperative complications. The role of systematic supplementation before bariatric surgery has to be explored in prospective studies.

This study aimed to assess the efficacy of daikenchuto (DKT), a commonly prescribed, traditional Japanese herbal medicine, on postoperative intestinal dysfunction after gastric cancer surgery. Patients with gastric cancer scheduled for a total gastrectomy were randomly assigned before surgery to receive either no treatment (n = 40; control group) or DKT (7.5 g/day, t.i.d.) for 3 months (n = 41) postoperatively. We examined gastrointestinal motility, stool attributes, the quantity of bowel gas, the quality of life, and the incidence of postoperative ileus. During the hospital stay, significant differences were observed between the DKT group and controls in the number of stools per day (1.1 ± 0.6 vs 0.8 ± 0.4, respectively; P = 0.037) and stool consistencies (Bristol scale ratings were 3.7 ± 0.8 vs 3.1 ± 0.8, respectively; P = 0.041). The DKT group showed significant reductions in gas volume scores, calculated from abdominal radiographs, at 7 days, 1 month, and 3 months after surgery. The groups did not show significant differences in quality of life scores (based on the Gastrointestinal Symptom Rating Scale) or in the incidence of postoperative ileus. DKT improved bowel movements, stool properties, and bowel gas. These results suggested that DKT promoted early postoperative bowel functions after total gastrectomy.

The clinical impact of intraoperative autofluorescence-based identification of parathyroids using a near-infrared camera remains unknown. In a before and after controlled study, we compared all patients who underwent total thyroidectomy by the same surgeon during Period 1 (January 2015 to January 2016) without near-infrared (near-infrared- group) and those operated on during Period 2 (February 2016 to September 2016) using a near-infrared camera (near-infrared+ group). In parallel, we also compared all patients who underwent surgery without near-infrared during those same periods by another surgeon in the same unit (control groups). Main outcomes included postoperative hypocalcemia, parathyroid identification, autotransplantation, and inadvertent resection. The near-infrared+ group displayed significantly lower postoperative hypocalcemia rates (5.2%) than the near-infrared- group (20.9%; P < .001). Compared with the near-infrared- patients, the near-infrared+ group exhibited an increased mean number of identified parathyroids and reduced parathyroid autotransplantation rates, although no difference was observed in inadvertent resection rates. Parathyroids were identified via near-infrared before they were visualized by the surgeon in 68% patients. In the control groups, parathyroid identification improved significantly from Period 1 to Period 2, although autotransplantation, inadvertent resection and postoperative hypocalcemia rates did not differ. Near-infrared use during total thyroidectomy significantly reduced postoperative hypocalcemia, improved parathyroid identification and reduced their autotransplantation rate.

The relative contribution of specific postoperative complications on mortality after emergency operations has not been previously described. Identifying specific contributors to postoperative mortality following acute care surgery will allow for significant improvement in the care of these patients. Patients from the 2005 to 2011 American College of Surgeons' National Surgical Quality Improvement Program database who underwent emergency operation by a general surgeon for one of seven diagnoses (gallbladder disease, gastroduodenal ulcer disease, intestinal ischemia, intestinal obstruction, intestinal perforation, diverticulitis, and abdominal wall hernia) were analyzed. Postoperative complications (pneumonia, myocardial infarction, incisional surgical site infection, organ/space surgical site infection, thromboembolic process, urinary tract infection, stroke, or major bleeding) were chosen based on surgical outcome measures monitored by national quality improvement initiatives and regulatory bodies. Regression techniques were used to determine the independent association between these complications and 30-day mortality, after adjustment for an array of patient- and procedure-related variables. Emergency operations accounted for 14.6% of the approximately 1.2 million general surgery procedures that are included in American College of Surgeons' National Surgical Quality Improvement Program but for 53.5% of the 19,094 postoperative deaths. A total of 43,429 emergency general surgery patients were analyzed. Incisional surgical site infection had the highest incidence (6.7%). The second most common complication was pneumonia (5.7%). Stroke, major bleeding, myocardial infarction, and pneumonia exhibited the strongest associations with postoperative death. Given its disproportionate contribution to surgical mortality, emergency surgery represents an ideal focus for quality improvement. Of the potential postoperative targets for quality improvement, pneumonia, myocardial

Many studies have implicated operative length as a predictor of post-operative complications, including venous thromboembolism [deep vein thrombosis (DVT) and pulmonary embolism (PE)]. We analyzed the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) database from 2006 to 2014, to evaluate whether length of operation had a statistically significant effect on post-operative complications in patients undergoing surgical resection of meningioma. Patients were included for this study if they had a post-operative diagnosis of meningioma. Patient demographics, pre-operative comorbidities, and post-operative 30-day complications were analyzed. Of 3743 patients undergoing craniotomy for meningioma, 13.6 % experienced any complication. The most common complications and their median time to occurrence were urinary tract infection (2.6 %) at 10 days postoperatively (IQR 7-15), unplanned intubation (2.5 %) at 3 days (IQR 1-7), failure to wean from ventilator (2.4 %) at 2.0 days (IQR 2-4), and DVT (2.4 %) at 6 days (IQR 11-19). Postoperatively, 3.6 % developed VTE; 2.4 % developed DVT and 1.7 % developed PE. Multivariable analysis identified older age (third and upper quartile), obesity, preoperative ventilator dependence, preoperative steroid use, anemia, and longer operative time as significant risk factors for VTE. Separate multivariable logistic regression models demonstrated longer operative time as a significant risk factor for VTE, all complications, major complications, and minor complications. Meningioma resection is associated with various post-operative complications that increase patient morbidity and mortality risk. this large, multi-institutional patient sample, longer operative length was associated with increased risk for postoperative venous thromboembolisms, as well as major and minor complications.

To describe pain severity and pain interference and to explore the impact of pain severity on postoperative health-related quality of life of older people during their first year after discharge for hip surgery in Taiwan. Few studies have examined the impact of pain on postoperative quality of life for hip-fractured older persons. A descriptive, correlational design was used for this longitudinal study. Pain intensity, pain interference and quality of life were investigated prospectively for 87 elders within 12 months after discharge for hip surgery at a medical centre in Taiwan. Pain intensity and pain interference were measured by items from the Bodily Pain scale of the Medical Outcomes Study Short Form-36, Taiwan version. Quality of life dimensions were measured by all instrument scales, except bodily pain. Moderate to severe pain was reported by 41.3% and 24(.)8% of subjects at one and 12 months following discharge, respectively. Pain interference with life was reported as quite a bit or extreme by 31.1% of subjects at 12 months after discharge. Subjects who reported moderate/severe pain at one month after discharge experienced declines in general health (p = 0.03) and vitality (p = 0.02) from 6-12 months after discharge. Around a quarter of hip-fractured older persons experienced moderate to very severe pain and quite a bit to severe pain interference from six months to one year after discharge. Furthermore, pain experienced during the first month after discharge significantly impacted quality of life throughout the year following discharge, even after controlling for covariates. Nurses must pay attention and intervene with long-term postoperative pain in hip-fractured elders to prevent further declines in physically related outcomes. The findings of this study can be used to develop effective pain-management strategies for hip-fractured older patients.

The management of asymptomatic patients with mitral regurgitation (MR) remains controversial. Exercise-induced pulmonary hypertension (ExPHT) was recently reported as a strong predictor of rapid onset of symptoms. We hypothesised that ExPHT is a predictor of postoperative cardiovascular events in patients with primary MR. One hundred and two patients with primary MR, no or mild symptoms (New York heart association (NYHA) ≤2), and no LV dysfunction/dilatation, were prospectively recruited in 3 centres and underwent exercise-stress echocardiography. The presence of ExPHT was defined as an exercise systolic pulmonary arterial pressure >60 mm Hg. All patients were closely followed up and operated on when indication for surgery was reached. Postoperative events were defined as the occurrence of atrial fibrillation (AF), stroke, cardiac-related hospitalisation or death. Among the 102 patients included, 59 developed ExPHT (58%). These patients were significantly older than those without ExPHT (p=0.01). During a mean postoperative follow-up of 50±23 months, 28 patients (26%) experienced a predefined cardiovascular event. Patients with ExPHT had significantly higher rate of postoperative events (39% vs 12%, p=0.005); the rate of events was still higher in these patients (32% vs 9%, p=0.013), even when excluding early postoperative AF (ie, within 48 h). Event-free survival was significantly lower in the ExPHT group (all events: 5-year: 60±8% vs 88±5%, p=0.007, events without early AF: 5-year: 67±7% vs 90±4%, p=0.02). Using Cox multivariable analysis, ExPHT remained independently associated with higher risk of postoperative events in all models (all p≤0.04). ExPHT is associated with increased risk of adverse cardiac events following mitral valve surgery in patients with primary MR. Published by the BMJ Publishing Group Limited.

The aim of this study was to investigate the impact of Daikenchuto (DKT) on early postoperative outcomes after living donor liver transplantation (LDLT), focusing on the prevention of abdominal distension and bacterial translocation. Adult LDLT recipients were prospectively divided into 2 groups, who were administered DKT (n = 20, group A) or not (n = 20, group B). The area of bowel gas defined as gas volume score (GVS) 7 days after LDLT was calculated. Postoperative liver function tests, the development of bacterial, viral, and fungal infections, and GVS after LDLT were reviewed. There were no significant differences in liver function tests and ammonia level after LDLT. Also, the rates of infection and the result of culture study were not different between groups. The median GVS 7 days after LDLT was not significantly different between groups A (0.26 (range, 0.12-0.58)) and B (0.23 (range, 0.15-0.42)). No positive impact was observed for 14-day DKT administration after LDLT, in terms of preventing infection or abdominal distension. Copyright © 2018. Published by Elsevier Taiwan.

Nephrolithiasis has been reported in 20-28% of patients, of whom 50% are symptomatic for stone disease and 20% require definite urologic intervention. The management of nephrolithiasis includes oral alkali dissolution therapy, extracorporeal shock wave lithotripsy and surgical treatment. In such patients, percutaneous nephrolithotomy (PNL) as a method of stone treatment has been reported in few cases with limited experience. The aim of this study is to present our experience of PNL in autosomal dominant polycystic kidney disease (ADPKD) and assessing the outcome results. From 2002 to 2011, 22 patients (26 renal units) suffering from ADPKD with stone were managed by PNL. Demographic characteristics, operative parameters and postoperative complications were recorded and analysed. The overall success rate of PNL was 82.1% and PNL with extracorporeal shock wave lithotripsy for clinically significant residual fragments was 92.85% respectively. The hematuria required blood transfusion (n = 9), postoperative fever due to cyst infection (n = 4) and paralytic ileus (n = 3) were recorded. The PNL in ADPKD PNL is safe and effective but have more postoperative complications such as bleeding requiring transfusions, fever due to cyst infection and paralytic ileus.

Recently, skeletal muscle depletion (sarcopenia) has been reported to influence postoperative outcomes after certain procedures. This study investigated the impact of sarcopenia on postoperative outcomes following pancreaticoduodenectomy (PD). We performed a retrospective study of consecutive patients (n = 219) who underwent PD at our institution between January 2007 and May 2013. Sarcopenia was evaluated using preoperative computed tomography. We evaluated postoperative outcomes and the influence of sarcopenia on short-term outcomes, especially infectious complications. Subsequently, multivariate analysis was used to assess the impact of prognostic factors (including sarcopenia) on postoperative infections. The mortality, major complication, and infectious complication rates for all patients were 1.4%, 16.4%, and 47.0%, respectively. Fifty-five patients met the criteria for sarcopenia. Sarcopenia was significantly associated with a higher incidence of in-hospital mortality (P = 0.004) and infectious complications (P < 0.001). In multivariate analyses, sarcopenia (odds ratio = 3.43; P < 0.001), preoperative biliary drainage (odds ratio = 2.20; P = 0.014), blood loss (odds ratio = 1.92; P = 0.048), and soft pancreatic texture (odds ratio = 3.71; P < 0.001) were independent predictors of postoperative infections. Sarcopenia is an independent preoperative predictor of infectious complications after PD. Clinical assessment combined with sarcopenia may be helpful for understanding the risk of postoperative outcomes and determining perioperative management strategies.

To compare postoperative outcomes in children undergoing cardiac surgery during the viral respiratory season and nonviral season at our institution. This was a retrospective cohort study and secondary matched case-control analysis. The setting was an urban academic tertiary-care children's hospital. The study was comprised of all patients <18 years of age who underwent cardiac surgery at Johns Hopkins Hospital from October 2002 through September 2007. Patients were stratified by season of surgery, complexity of cardiac disease, and presence or absence of viral respiratory infection. Measurements included patient characteristics and postoperative outcomes. The primary outcome was postoperative length of stay (LOS). A total of 744 patients were included in the analysis. There was no difference in baseline characteristics or outcomes, specifically, no difference in postoperative LOS, intensive care unit (ICU) LOS, and mortality, among patients by seasons of surgery. Patients with viral respiratory illness were more likely to have longer postoperative LOS (p < 0.01) and ICU LOS (p < 0.01) compared with matched controls. We identified no difference in postoperative outcomes based on season in patients undergoing cardiac surgery. Children with viral respiratory infection have significantly worse outcomes than matched controls, strengthening the call for universal administration of influenza vaccination and palivizumab to appropriate groups. Preoperative testing for respiratory viruses should be considered during the winter months for children undergoing elective cardiac surgery.

To identify the incidence and associated factors of the postoperative hydronephrosis in pediatric patients who underwent ureterorenoscopy (URS) for renal or ureteral stones. We evaluated the results of 116 patients who underwent semirigid or flexible URS retrospectively. Primary end points of the study were to determine the incidence of postoperative hydronephrosis and factors associated with the development of postoperative hydronephrosis. Logistic regression analysis was used to define factors associated with the presence of hydronephrosis. Mean age of the population was 9.5 years and mean stone size was 9.4 mm. Hydronephrosis was detected in 32 (27.6%) patients. Stone-free status was achieved in 101 (87%) patients. Univariate analysis revealed history of ipsilateral URS, duration of operation, presence of impacted stone, development of ureteral injury during operation, and presentation with a renal colic episode as the parameter associated with increased risk of hydronephrosis. History of ipsilateral URS (odds ratio: 1.664, P = .027), presence of impacted stones (odds ratio: 1.788, P = .014), and development of ureteral injury during operation (odds ratio: 1.106, P = .039) were found to be the independent markers of developing postoperative hydronephrosis in a multivariate analysis. Ipsilateral hydronephrosis following URS develops in a significant portion of patients. In patients with history of ipsilateral procedure and those with an impacted stone and had ureteral injury, the risk of postoperative hydronephrosis is higher; therefore, physicians should keep these parameters in mind in the decision-making process of selective imaging postoperatively.

We describe an unusual case of a 74-year-old woman who presented with signs and symptoms of small-bowel obstruction and a clinically appreciable, irreducible, left-sided lumbar hernia associated with previous iliac crest bone graft harvesting. Palpation of the hernia demonstrated a small, firm mass within the loops of herniated bowel. CT scanning recognised an intraluminal gallstone at the transition point, establishing the diagnosis of gallstone ileus within an incarcerated lumbar hernia. The proposed explanatory mechanism is that of a gallstone migrating into an easily reducible hernia containing small bowel causing obstruction at the hernia neck by a ball-valve mechanism, resulting in proximal bowel dilation and thus hernia incarceration; it remains unclear when the stone entered the hernia, and whether it enlarged in situ or prior to entering the enteral tract. This is only the second reported instance in the literature of an intraluminal gallstone causing hernia incarceration. 2014 BMJ Publishing Group Ltd.

To investigate the impact of the orientation of preoperative corneal astigmatism on achieving the postoperative target refraction following monofocal intraocular lens (IOL) implantation. This study enrolled 339 eyes who had uneventful cataract surgery or refractive lens exchange (RLE) with subsequent monofocal IOL implantation. Eyes were initially categorized dependent upon axial length and then on the orientation of preoperative anterior corneal astigmatism. Group 1 had against-the-rule (ATR) anterior corneal astigmatism, group 2 had with-the-rule (WTR) anterior corneal astigmatism, and group 3 had oblique (OB) anterior corneal astigmatism. The preoperative corneal astigmatism was determined by the IOLMaster (Carl Zeiss Meditec AG). Postoperative refraction was completed for all eyes, and the results were calculated and compared for the separate groups. In eyes with axial lengths greater than 22.0 mm and less than 25.0 mm there was a significant difference between the magnitude of preoperative corneal astigmatism between groups 2 and 3 with 0.827 ± 0.376 D in group 2, and 0.677 ± 0.387 D in group 3. The mean postoperative spherical equivalent (SE) prediction error was - 0.132 ± 0.475 D in group 1, 0.026 ± 0.497 D in group 2, and - 0.130 ± 0.477 D in group 3. There was a significant difference between groups 1 and 2. There was no significant difference in the magnitude of preoperative corneal astigmatism and postoperative SE prediction error between the anterior corneal astigmatism orientation groups in eyes with axial lengths of less than or equal to 22.0 mm and greater than or equal to 25.0 mm. The orientation of preoperative anterior corneal astigmatism significantly affected the postoperative biometry prediction error in eyes with astigmatism of 1.75 D or less in eyes with the axial length between 22.0 mm and 25.0 mm. However, the results were not clinically significant.

This study aimed to determine the predictors of ipsilateral hydronephrosis after ureteroscopic lithotripsy for ureteral calculi. From January 2010 to December 2014, a total of 204 patients with ureteral calculi who underwent ureteroscopic lithotripsy were reviewed. Patients with lack of clinical data, presence of ureteral rupture, and who underwent simultaneous percutaneous nephrolithotomy (PNL) were excluded. Postoperative hydronephrosis was determined via computed tomographic scan or renal ultrasonography, at 6 months after ureteroscopic lithotripsy. Multivariable analysis was performed to determine clinical factors associated with ipsilateral hydronephrosis. A total of 137 patients were enrolled in this study. The mean age of the patients was 58.8±14.2 years and the mean stone size was 10.0±4.6 mm. The stone-free rate was 85.4%. Overall, 44 of the 137 patients (32.1%) had postoperative hydronephrosis. Significant differences between the hydronephrosis and nonhydronephrosis groups were noted in terms of stone location, preoperative hydronephrosis, impacted stone, operation time, and ureteral stent duration (all, p<0.05). On multivariable analysis, increasing preoperative diameter of the hydronephrotic kidney (adjusted odds ratio [OR], 1.21; 95% confidence interval [CI], 1.12-1.31; p=0.001) and impacted stone (adjusted OR, 3.01; 95% CI, 1.15-7.61; p=0.031) independently predicted the occurrence of postoperative hydronpehrosis. Large preoperative diameter of the hydronephrotic kidney and presence of impacted stones were associated with hydronephrosis after ureteroscopic stone removal. Therefore, patients with these predictive factors undergo more intensive imaging follow-up in order to prevent renal deterioration due to postoperative hydronephrosis.

To determine the effect of a critical pathway on postoperative length of stay and outcomes after infrainguinal bypass. A critical pathway for care of patients after infrainguinal bypass was introduced in December 1995 to coordinate postoperative care at our institution. We compared care of 67 consecutively treated patients before institution of the pathway with care of 69 consecutively treated patients with the critical pathway in place. Data collection was done by means of chart review. Univariate analyses were used to identify differences between prepathway and postpathway patients and to identify factors influencing postoperative length of stay. Multivariate analysis was used to identify factors that influenced length of stay and to examine the effect of use of the pathway after adjusting for other factors. Patients on the pathway were similar to prepathway controls with respect to comorbid illnesses, vascular risk factors, indications for surgical treatment, type of conduit, and type of operation. Factors associated with longer postoperative stays included distal anastomoses to tibial rather than popliteal vessels (p = 0.02), preexisting cardiac disease (p = 0.005), postoperative complications (p = 0.0003), lower preoperative hematocrit (p = 0.01), and elevated preoperative creatinine level (p = 0.006). Overall, pathway patients had somewhat shorter postoperative lengths of stay (median value 7 days; range 2 to 29 days) than prepathway patients (median value 6 days; range 2 to 35; p = 0.01), and the two groups had similar frequencies of postoperative complications, readmission, and 6-month mortality. However, patients on the pathway were more likely to be discharged to an intermediate-care facility rather than directly home. After 12 patients with extraordinarily prolonged postoperative stays were excluded, multivariate analysis indicated that pathway patients had significantly shorter postoperative stays (p = 0.001). However, the difference was not significant

Although some surgeons prescribe prolonged postoperative antibiotics after autologous breast reconstruction, evidence is lacking to support this practice. We used the Tracking Operations and Outcomes for Plastic Surgeons database to evaluate the association between postoperative antibiotic duration and the rate of surgical site infection (SSI) in autologous breast reconstruction. The intervention of interest for this study was postoperative duration of antibiotic prophylaxis: either discontinued 24 hours after surgery or continued beyond 24 hours. The primary outcome variable of interest for this study was the presence of SSI within 30 days of autologous breast reconstruction. Cohort characteristics and 30-day outcomes were compared using χ² and Fischer exact tests for categorical variables and Student t tests for continuous variables. Multivariate logistic regression was used to control for confounders. A total of 1036 patients met inclusion criteria for our study. Six hundred fifty-nine patients (63.6%) received antibiotics for 24 hours postoperatively, and 377 patients (36.4%) received antibiotics for greater than 24 hours. The rate of SSI did not differ significantly between patients given antibiotics for only 24 hours and those continued on antibiotics beyond the 24-hour postoperative time period (5.01% vs 2.92%, P = 0.109). Furthermore, antibiotic duration was not predictive of SSI in multivariate regression modeling. We did not find a statistically significant difference in the rate of SSI in patients who received 24 hours of postoperative antibiotics compared to those that received antibiotics for greater than 24 hours. These findings held for both purely autologous reconstruction as well as latissimus dorsi reconstruction in conjunction with an implant. Thus, our study does not support continuation of postoperative antibiotics beyond 24 hours after autologous breast reconstruction.

Gastric cancer is a major health problem, and frailty and sarcopenia will affect the postoperative outcomes in older people. However, there is still no systematic review to determine the role of frailty and sarcopenia in predicting postoperative outcomes among older patients with gastric cancer who undergo gastrectomy surgery. We searched Embase, Medline through the Ovid interface and PubMed websites to identify potential studies. All the search strategies were run on August 24, 2016. We searched the Google website for unpublished studies on June 1, 2017. The data related to the endpoints of gastrectomy surgery were extracted. Odds ratios (ORs) and their 95% confidence intervals (CIs) were pooled to estimate the association between sarcopenia and adverse postoperative outcomes by using Stata version 11.0. PRISMA guidelines for systematic reviews were followed. After screening 500 records, we identified eight studies, including three prospective cohort studies and five retrospective cohort studies. Only one study described frailty, and the remaining seven studies described sarcopenia. Frailty was statistically significant for predicting hospital mortality (OR 3.96; 95% CI: 1.12-14.09, P = 0.03). Sarcopenia was also associated with postoperative outcomes (pooled OR 3.12; 95% CI: 2.23-4.37). No significant heterogeneity was observed across these pooled studies (Chi 2  = 3.10, I 2  = 0%, P = 0.685). Sarcopenia and frailty seem to have significant adverse impacts on the occurrence of postoperative outcomes. Well-designed prospective cohort studies focusing on frailty and quality of life with a sufficient sample are needed.

Pulsed electromagnetic fields (PEMF) reduce postoperative pain and narcotic requirements in breast augmentation, reduction, and reconstruction patients. PEMF enhances both calmodulin-dependent nitric oxide and/or cyclic guanosine monophosphate signaling and phosphodiesterase activity, which blocks cyclic guanosine monophosphate. The clinical effect of these competing responses on PEMF dosing is not known. Two prospective, nonrandomized, active cohorts of breast reduction patients, with 15 min PEMF per 2 h; "Q2 (active)", and 5 min PEMF per 20 min; "5/20 (active)", dosing regimens were added to a previously reported double-blind clinical study wherein 20 min PEMF per 4 h, "Q4 (active)", dosing significantly accelerated postoperative pain reduction compared with Q4 shams. Postoperative visual analog scale pain scores and narcotic use were compared with results from the previous study. Visual analog scale scores at 24 h were 43% and 35% of pain at 1 h in the Q4 (active) and Q2 (active) cohorts, respectively (P < 0.01). Pain at 24 h in the 5/20 (active) cohort was 87% of pain at 1 h, compared with 74% in the Q4 (sham) cohort (P = 0.451). Concomitantly, narcotic usage in the 5/20 (active) and Q4 (sham) cohorts was not different (P = 0.478), and 2-fold higher than the Q4 (active) and Q2 (active) cohorts (P < 0.02). This prospective study shows Q4/Q2, but not 5/20 PEMF dosing, accelerated postoperative pain reduction compared with historical shams. The 5/20 (active) regimen increases NO 4-fold faster than the Q4 (active) regimen, possibly accelerating phosphodiesterase inhibition of cyclic guanosine monophosphate sufficiently to block the PEMF effect. This study helps define the dosing limits of clinically useful PEMF signals. Copyright © 2015 Elsevier Inc. All rights reserved.

Sleep disordered breathing (SDB) is common in patients with coronary disease, but its impact on post-operative recovery after coronary artery bypass graft surgery (CABG) is unclear. We therefore determined the effects of SDB on post-operative outcome after elective CABG.In this prospective two-centre study, 219 patients due to receive elective CABG underwent cardiorespiratory polygraphy for SDB prior to surgery and were monitored for post-operative complications. The primary end-point was a composite of 30-day mortality or major post-operative complications (cardiac, respiratory, surgical, infectious, acute renal failure or stroke). Key secondary end-points were single components of the primary end-point.SDB was present in 69% and moderate/severe SDB in 43% of the CABG patients. There was no difference in the composite of 30-day mortality or major postoperative complications between patients with and without SDB (OR 0.97, 95% CI 0.49-1.96) and between patients with moderate/severe SDB and no/mild SDB (OR 1.07, 95% CI 0.55-2.06). However, moderate/severe SDB was associated with higher rates of mortality (crude OR 10.1, 95% CI 1.22-83.5), sepsis (OR 2.96, 95% CI 1.17-7.50) and respiratory complications (OR 2.85, 95% CI 1.46-5.55).Although SDB was not associated with higher overall morbidity/mortality, moderate/severe SDB may increase the risk of death, and septic and respiratory complications, after elective CABG.

Preoperative teaching is an important part of patient care and can prevent complications, as well as promote patient fulfillment during hospitalization. A study was conducted at Alton Ochsner Medical Foundation in New Orleans, LA, in 1989, to determine the impact of a preoperative teaching program on the incidence of postoperative atelectasis and patient satisfaction. Results showed no significant difference of postoperative complications and patient gratification after participating in a structured preoperative teaching program. As part of this study, it was identified that a patient evaluation tool for a preoperative teaching class needed to be developed. The phases of this process are explained in the following article.

Despite modern advancements in transosseous fixation and operative technique, hallux valgus (i.e., bunion) surgery is still associated with a higher than usual amount of patient dissatisfaction and is generally recognized as a complex and nuanced procedure requiring precise osseous and capsulotendon balancing. It stands to reason then that familiarity and skill level of trainee surgeons might impact surgical outcomes in this surgery. The aim of this study was to determine whether podiatry resident experience level influences midterm outcomes in hallux valgus surgery (HVS). Consecutive adults who underwent isolated HVS via distal metatarsal osteotomy at a single US metropolitan teaching hospital from January 2004 to January 2009 were contacted and asked to complete a validated outcome measure of foot health (Manchester-Oxford Foot Questionnaire) regarding their operated foot. Resident experience level was quantified using the surgical logs for the primary resident of record at the time of each case. Associations were assessed using linear and logistic regression analyses. A total of 102 adult patients (n = 102 feet) agreed to participate with a mean age of 46.8 years (standard deviation 13.1, range 18-71) and average length of follow-up 6.2 y (standard deviation 1.4, range 3.6-8.6). Level of trainee experience was not associated with postoperative outcomes in either the univariate (odds ratio 0.99 [95% confidence interval, 0.98-1.01], P = 0.827) or multivariate analyses (odds ratio 1.00 [95% confidence interval, 0.97-1.02], P = 0.907). We conclude that podiatry resident level of experience in HVS does not contribute appreciably to postoperative clinical outcomes. Copyright © 2014 Elsevier Inc. All rights reserved.

Introduction To evaluate the impact of intermittent portal clamping (IPC) on long-term postoperative outcomes in patients with hepatocellular carcinoma (HCC). Methods Clinical records of 355 patients underwent curative liver resection for HCC in January 2007 to December 2010 were retrospectively reviewed. According to how portal clamping was performed, patients were grouped as: IPC, n=113; other portal clamping (OPC), n=190; and no portal clamping (NPC), n=52. Results Median recurrence-free survival (RFS) was statistically significantly shorter in the IPC (39.4 months) than OPC (47.3 months, p=0.010) and NPC groups (51.4 months, p=0.008). Median overall survival (OS) was also significantly shorter with IPC (46.3 months), versus 52.9 months with OPC (p=0.022) and 56.2 months with NPC (p=0.015). Kaplan-Meier survival analysis revealed that 5-year cumulative RFS was much lower in the IPC (42.5%) than OPC (50.9%, p=0.014) and NPC groups (49.6%, p=0.013). Five-year cumulative OS was also much lower in the IPC (44.9%) than OPC (58.0%, p=0.020) and NPC groups (57.7%, p=0.025). On univariate analysis, tumour grade, size and number, TNM stage, blood transfusion, vascular invasion and IPC were significantly inversely correlated with RFS and OS. On multivariate analysis, tumour size and number, blood transfusion, vascular invasion and IPC remained significant. Conclusions Our study suggests that IPC is an independent risk factor for poor long-term postoperative outcomes in patients with HCC.

The feasibility and safety of robotically assisted procedures in general surgery have been reported from various groups worldwide. Because postoperative complications may lead to longer hospital stays and higher costs overall, analysis of risk factors for postoperative surgical complications in this subset of patients is clinically relevant. The goal of this study was to identify risk factors for postoperative morbidity after robotic surgical procedures in general surgery. We performed an observational monocentric retrospective study. All consecutive robotic surgical procedures from November 2001 to December 2013 were included. One thousand consecutive general surgery patients met the inclusion criteria. The mean overall postoperative morbidity and major postoperative morbidity (Clavien >III) rates were 20.4 and 6 %, respectively. This included a conversion rate of 4.4 %, reoperation rate of 4.5 %, and mortality rate of 0.2 %. Multivariate analysis showed that ASA score >3 [OR 1.7; 95 % CI (1.2-2.4)], hematocrit value <38 [OR 1.6; 95 % CI (1.1-2.2)], previous abdominal surgery [OR 1.5; 95 % CI (1-2)], advanced dissection [OR 5.8; 95 % CI (3.1-10.6)], and multiquadrant surgery [OR 2.5; 95 % CI (1.7-3.8)] remained independent risk factors for overall postoperative morbidity. It also showed that advanced dissection [OR 4.4; 95 % CI (1.9-9.6)] and multiquadrant surgery [OR 4.4; 95 % CI (2.3-8.5)] remained independent risk factors for major postoperative morbidity (Clavien >III). This study identifies independent risk factors for postoperative overall and major morbidity in robotic general surgery. Because these factors independently impacted postoperative complications, we believe they could be taken into account in future studies comparing conventional versus robot-assisted laparoscopic procedures in general surgery.

Understanding postoperative fatigue.

PubMed

Rose, E A; King, T C

1978-07-01

Performance characteristics of the central nervous, cardiovascular, respiratory and muscular systems in man postoperatively have received little investigative attention, despite the well known syndrome of postoperative fatigue. The impairmen in perception and psychomotor skills that has been shown to result from caloric restriction, bedrest, sedation and sleep deprivation suggests that a similar deficit may occur after surgical procedures. After a simple elective surgical procedure, maximal oxygen uptake decreases and the adaptability of heart rate to submaximal workloads is impaired. Similar deleterious effects on cardiorespiratory performance have been documented with starvation and bedrest; an understanding of cardiorespiratory performance postoperatively awaits further investigation. Maximal muscular force of contraction is also impaired by caloric restriction and bedrest, suggesting that similar effects may be seen in the postoperative state, although this has not been studied. A better understanding of the syndrome of postoperative fatigue could be achieved by a descriptive analysis of physiologic performance postoperatively. Such descriptive data could form the basis for objective evaluation of therapeutic measures intended to improve performance, such as nutritional supplementation and pharmacologic intervention. The observation that exercise with the patient in the supine position may decrease the impairment in maximal aerobic power otherwise expected in immobilized patients suggests that controlled exercise therapy may be of value in reducing physiologic impairment postoperatively.

180 total thyroidectomy case studies performed by the same operator in the years 2006-2010, all done with sutureless technique (Ligasure precise(®)). The monitoring of patients involved a dose of serum calcium on the 1st, 2nd, 3rd and seventh post-operative, before the ambulatory monitoring of the patient. Treatment of post-operative thyroidectomy also includes the administration from the first day of post-surgery, of 2 g/day of calcium (calcium lactate gluconate 2940 mg, calcium carbonate 300 mg). Hypocalcemia was observed in 27 cases (15%) of which 23/180 (12.8%) were transitional and 4/180 (2.2%) were permanent. The average postoperative hospitalization was 2.5 days with a minimum of 30 h. The peak of hypocalcemia was of 11 patients on the first postoperative day (40.7%) in 6 patients on the second postoperative day (22.2%), in 8 patients on the third postoperative day (29.6%), in 1 patient on the fourth postoperative day (3.7%) and in another one on the fifth postoperative day (3.7%). The second postoperative day is crucial for the determination of early discharge (24-30 h). When the surgeon identifies and manages to preserve at least 3 parathyroid glands during surgery, the risk of hypocalcemia together with evaluations of serum calcium on the first and second post-operative day, eliminates the hypocalcemic risk.

Individual response to opioid analgesics varies among patients. This study sought to clarify the impact of distinct genetic variations on pain, opioid consumption, and opioid side effects in patients with postoperative pain. A systematic review and meta-analysis of associations between genetic single-nucleotide polymorphisms (SNPs) and opioids used for acute postoperative pain. This meta-analysis examined all studies involving an association between genetic polymorphisms and the analgesic efficacy or clinical outcome of opioid analgesics for postoperative pain. A literature search was performed up to January 31, 2014, using the PubMed, EMBase, ISI Web of Science, and Cochrane Library databases. Fifty-nine studies were included in this systematic review, and 23 studies (a total of 5,902 patients) were included in the final meta-analysis. The results showed that human μ-opioid receptor gene (OPRM1) 118G allele variant carriers consumed more opioids for analgesia (SMD = -0.17, 95% CI = [-0.25, -0.10], P < 0.00001), but reported higher pain scores (MD = -0.11, 95% CI = [-0.17, -0.04], P = 0.002) and less nausea and vomiting (odds ratio = 1.30, 95% CI = [1.08, 1.55], P = 0.005) than the homozygous 118AA patients during the first 24 hour but not the 48 hour postoperative period. Moreover, CYP3A4*1G carriers consumed less opioids than homozygous CYP3A4*1/*1 patients during the first 24 hours postoperative period (MD = 45.12, 95% CI = [36.17, 54.06], P < 0.00001). No significant differences were found in CYP3A5*3, ABCB1 C3435T, and G2477T/A genetic polymorphisms. Some potential non-genetic factors can modify the effects of gene SNP on pain and opioid consumption during the postoperative period, such as age, gender, mood, anxiety, and drug-drug interactions. But further analyses could not be performed in the present meta-analysis due to limited information. The results indicate that among the genetic SNPs we studied which include those affecting analgesic drug metabolism

The prevention of postoperative complications is of prime importance after complex elective abdominal operations. Preoperative patient education may prevent postoperative complications and improve patients' wellbeing, but evidence for its efficacy is poor. The aims of the PEDUCAT trial were (a) to assess the impact of preoperative patient education on postoperative complications and patient-reported outcomes in patients scheduled for elective complex visceral surgery and (b) to evaluate the feasibility of cluster randomization in this setting. Adult patients (age ≥ 18 years) scheduled for elective major visceral surgery were randomly assigned in clusters to attend a preoperative education seminar or to the control group receiving the department's standard care. Outcome measures were the postoperative complications pneumonia, deep vein thrombosis (DVT), pulmonary embolism, burst abdomen, and in-hospital fall, together with patient-reported outcomes (postoperative pain, anxiety and depression, patient satisfaction, quality of life), length of hospital stay (LOS), and postoperative mortality within 30 days after the index operation. Statistical analysis was primarily by intention to treat. In total 244 patients (60 clusters) were finally included (intervention group 138 patients; control group 106 patients). Allocation of hospital wards instead of individual patients facilitated study conduct and reduced confusion about group assignment. In the intervention and control groups respectively, pneumonia occurred in 7.4% versus 8.3% (p = 0.807), pulmonary embolism in 1.6% versus 1.0% (p = 0.707), burst abdomen in 4.2% versus 1.0% (p = 0.165), and in-hospital falls in 0.0% versus 4.2% of patients (p = 0.024). DVT did not occur in any of the patients. Mortality rates (1.4% versus 1.9%, p = 0.790) and LOS (14.2 (+/- 12.0) days versus 16.1 (+/- 15.0) days, p = 0.285) were also similar in the intervention and control groups. Cluster

To investigate whether preoperative enteral diets -enriched in eicosapentaenoic acid (EPA) supplements could reduce the incidence of hypercytokinemia after pancreatoduodenectomy (PD) in a double-blinded randomized -controlled trial. Patients with resectable periampullary cancer were randomized into either the control group or the treatment group. Patients in the treatment group received oral supplementation (600 kcal/day) containing EPA for 7 days before surgery. Patients in the control group received isocaloric isonitrogenous standard nutrition (600 kcal/day) without EPA for 7 days before surgery. The primary endpoint was postoperative serum concentrations of interleukin-6 (IL-6). The secondary endpoints were the postoperative nutritional status and the incidence of postoperative infectious complications. Twenty-four patients were enrolled in the present study. After exclusion, 20 patients (control group, n = 9; treatment group, n = 11) were analyzed. There were no significant differences in the curves for the serum concentration of IL-6 (p = 0.68) or the incidence of infectious complications between the 2 groups (control group: 78%, treatment group: 55%, p = 0.37). The results of a double-blinded randomized controlled trial indicated that preoperative immunonutrition had no marked impact on the rates of postoperative hypercytokinemia or infectious complications after PD. © 2018 S.

The objective of this study was to clarify significant risk factors for postoperative complications in the oral cavity in patients who underwent oral surgery, excluding those with oral cancer. This study reviewed the records of 324 patients who underwent mildly to moderately invasive oral surgery (e.g., impacted tooth extraction, cyst excision, fixation of mandibular and maxillary fractures, osteotomy, resection of a benign tumor, sinus lifting, bone grafting, removal of a sialolith, among others) under general anesthesia or intravenous sedation from 2012 to 2014 at the Department of Oral and Maxillofacial Reconstructive Surgery, Hiroshima University Hospital. Univariate analysis showed a statistical relationship between postoperative complications (i.e., surgical site infection, anastomotic leak) and diabetes (p=0.033), preoperative serum albumin level (p=0.009), and operation duration (p=0.0093). Furthermore, preoperative serum albumin level (<4.0 g/dL) and operation time (≥120 minutes) were found to be independent factors affecting postoperative complications in multiple logistic regression analysis results (odds ratio 3.82, p=0.0074; odds ratio 2.83, p=0.0086, respectively). Our results indicate that a low level of albumin in serum and prolonged operation duration are important risk factors for postoperative complications occurring in the oral cavity following oral surgery.

Postoperative infection increases cancer recurrence and worsens survival in colorectal cancer, but the relationship for esophagogastric adenocarcinoma after esophagectomy is not well defined. We aimed to determine whether recurrence and survival after minimally invasive esophagectomy for esophagogastric adenocarcinoma were influenced by postoperative infection using propensity-matched analysis. We abstracted data for 810 patients (1997-2010) and defined exposure as at least 1 in-hospital or 30-day infectious complication (n = 206 [25%]). Using 29 pretreatment/intraoperative variables, patients were propensity-score matched (caliper = 0.05). Time to cancer recurrence and survival (Kaplan-Meier curves and the Breslow test), and associated factors (Cox regression with shared frailty) were assessed. After propensity matching (n = 167 pairs), median bias across propensity-score variables was reduced from 12.9% (p < 0.001) to 4.4% (p = 1.000). Postoperative infection was not associated with rate (n = 60 versus 63; McNemar p = 0.736) or time to recurrence in those in whom disease recurred (median, 10.7 versus 11.1 months; Wilcoxon signed-rank p = 0.455) but was associated with shorter overall survival (n = 124 versus 102 deaths; median, 26 versus 41 months; Breslow p = 0.002). After adjusting for age, body mass index, neoadjuvant therapy, sex, comorbidity score, positive resection margins, pathologic stage, R0 resection, and recurrence, postoperative infection was associated with a 44% greater hazard for death (hazard ratio, 1.44; 95% confidence interval, 1.10-1.89). In patients with esophagogastric adenocarcinoma, infections after esophagectomy were not associated with an increased rate or earlier time to recurrence when baseline characteristics associated with infection risk were balanced using propensity-score matching. Despite this, overall survival was shorter in patients with infectious complications. After adjusting for other important survival predictors

Daikenchuto (DKT) has widely been used to improve abdominal symptoms by being expected to accelerate bowel motility. The purpose of this study is to examine the efficacy and safety of DKT for prevention of ileus and associated gastrointestinal symptoms after total gastrectomy. Two hundred and forty-five gastric cancer patients who underwent total gastrectomy were enrolled. Patients received either DKT (15.0 g/d) or matching placebo from postoperative days 1 to 12. Primary end points were time to first flatus, time to first bowel movement (BM), and frequency of BM. Secondary end points included quality of life, C-reactive protein level, symptoms indicative of a severe gastrointestinal disorder, and incidence of postoperative ileus. A total of 195 patients (DKT, n = 96; placebo, n = 99) were included in the per-protocol set analysis. There were no significant differences between the groups in terms of patient background characteristics. Median time to first BM was shorter in the DKT group than in the placebo group (94.7 hours vs 113.9 hours; p = 0.051). In patients with high medication adherence, median time to first BM was significantly shorter in the DKT group than in the placebo group (93.8 hours vs 115.1 hours; p = 0.014). Significantly fewer patients in the DKT group had ≥2 symptoms of gastrointestinal dysfunction than those in the placebo group on postoperative day 12 (p = 0.026). Administration of DKT during the immediate postoperative period after total gastrectomy appears to promote early recovery of postoperative bowel function.

The impact of vedolizumab, a gut-selective monoclonal antibody, on postoperative outcomes is unclear. This study aimed to assess the impact of preoperative vedolizumab treatment on the rate of postoperative complications in patients with inflammatory bowel disease [IBD] undergoing abdominal surgery. A systematic search of multiple electronic databases from inception until May 2017 identified studies reporting rates of postoperative complications in vedolizumab-treated IBD patients compared to no biologic exposure or anti-tumor necrosis factor (anti-TNF) treated IBD patients. Outcomes of interest included postoperative infectious complications and overall postoperative complications. Pooled risk ratios and 95% confidence intervals were estimated using the random-effects model. Five studies comprising 307 vedolizumab-treated IBD patients, 490 anti-TNF-treated IBD patients and 535 IBD patients not exposed to preoperative biologic therapy were included. The risk of postoperative infectious complications (risk ratio [RR] 0.99, 95% confidence interval [CI] 0.37-2.65) and overall postoperative complications [RR 1.00, 95% CI 0.46-2.15] were not significantly different between vedolizumab-treated patients and those who received no preoperative biologic therapy. In addition, the risk of postoperative infectious complications [RR 0.99, 95% CI 0.34-2.90] and overall postoperative complications [RR 0.92, 95% CI 0.44-1.92] were not significantly different between vedolizumab-treated vs anti-TNF-treated patients. Preoperative vedolizumab treatment in IBD patients does not appear to be associated with an increased risk of postoperative infectious or overall postoperative complications compared to either preoperative anti-TNF therapy or no biologic therapy. Future prospective studies which include perioperative drug level monitoring are needed to confirm these findings.

To evaluate the impact of rectal balloon (RB) inflation on post-transurethral resection of the prostate (TURP) bleeding in patients with symptomatic benign prostatic hyperplasia. After institutional review board approval, patients who were eligible for TURP were randomized into two equal groups, depending on whether they received postoperative endorectal balloon (RB) (GII) or not (GI). The tip of three-way Foley catheter was fixed to a balloon by a blaster strip to prepare air-tight RB. Postoperatively, the RB was inflated for 15 minutes by a pressure-controlled sphygmomanometer. Perioperative data were compared between both groups, including hemoglobin (Hb) deficit 24-hour postoperatively and at time of discharge. Functional outcomes, anorectal complaints, and adverse events were assessed perioperatively and after 1 and 3 months. Fifty patients were enrolled, including 13 (26%) patients who presented with indwelling urethral catheters. Baseline data and mean resected tissue weight were comparable between both groups, including preoperative Hb (p = 0.17). Immediate postoperative Hb deficit was, comparable between GI and GII patients (0.58 ± 0.18 vs 0.60 ± 0.2, p = 0.56) before RB inflation, respectively. However, compared to GI patients, mean Hb deficit significantly decreased in GII patients 24-hour postoperatively (0.2 ± 0.2 vs 0.7 ± 0.3 g, p = 0.002) and at time of discharge (0.8 ± 0.2 vs 1.3 ± 0.4 g, p = 0.003). GII patients needed significantly less postoperative irrigation (2.1 ± 1.6 vs 8.3 ± 1.8 L, p < 0.001), shorter catheterization time (2.3 ± 0.8 vs 3.8 ± 1.3 days, p < 0.001), and shorter hospital stay (2.6 ± 0.5 vs 4.3 ± 1.0 days, p < 0.001). Both groups were comparable in all functional outcomes at the most recent follow-up. Blood transfusion was needed in only one patient (4%) in GI. No patient needed recystoscopy for hematuria or clot retention in either

To determine the effect of body mass index on postoperative complications and the performance of lymph node dissection in women undergoing laparoscopy or laparotomy for endometrial cancer. Retrospective chart review of all patients undergoing surgery for endometrial cancer between 8/2004 and 12/2008. Complications graded and analyzed using Common Toxicity Criteria for Adverse Events ver. 4.03 classification. 168 women underwent surgery: laparoscopy n=65, laparotomy n=103. Overall median body mass index 36.2 (range, 18.1 to 72.7) with similar distributions for age, body mass index and performance of lymph node dissection between groups. Following laparoscopy vs. laparotomy the percent rate of overall complications 53.8:73.8 (p=0.01), grade ≥3 complications 9.2:34.0 (p<0.01), ≥3 wound complications 3.1:22.3 (p<0.01) and ≥3 wound infection 3.1:20.4 (p=0.01) were significantly lower after laparoscopy. In a logistic model there was no effect of body mass index (≥36 and<36) on complications after laparoscopy in contrast to laparotomy. Para-aortic lymph node dissection was performed by laparoscopy 19/65 (29%): by laparotomy 34/103 (33%) p=0.61 and pelvic lymph node dissection by laparoscopy 21/65 (32.3%): by laparotomy 46/103 (44.7%) p=0.11. Logistic regression analysis revealed that for patients undergoing laparoscopy for stage I disease there was an inverse relationship between the performance of both para-aortic lymph node dissection and pelvic lymph node dissection and increasing body mass index (p=0.03 and p<0.01 respectively) in contrast to the laparotomy group where there was a trend only (p=0.09 and 0.05). For patients undergoing laparoscopy, increasing body mass index did not impact postoperative complications but did influence the decision to perform lymph node dissection.

Postoperative paralytic ileus can be a difficult complication for both surgeons and patients. Causes and treatments have been discussed for more than two centuries, but have not yet been fully resolved. Daikenchuto (TJ-100, DKT) is a traditional Japanese herbal medicine. Recently, some beneficial mechanisms of DKT to relieve paralytic ileus have been reported. DKT can suppress inflammation, increase intestinal blood flow, and accelerate bowel movements. Therefore, we have designed a randomized controlled trial to investigate the effects of DKT on postoperative gastrointestinal symptoms following laparoscopic colectomy in patients with left-sided colon cancer at a single institution. As primary endpoints, the following outcomes will be evaluated: (i) grade of abdominal pain determined using the numeric rating scale (NRS), (ii) grade of abdominal distention determined using the NRS, and (iii) quality of life determined using the Gastrointestinal Quality Life Index (GIQLI). As secondary endpoints, the following will be evaluated: (i) postoperative nutritional status (Onodera's Prognostic Nutritional Index (PNI) and the Controlling Nutritional Status score (CONUT score)), (ii) duration to initial flatus, (iii) duration to initial defecation, (iv) bowel gas volume, (v) character of stool (Bristol Stool Form Scale), (vi) defecation frequency per day, (vii) postoperative complications (Clavien-Dindo classification), (viii) length of postoperative hospital stay, and (ix) metabolites in the stool and blood. This trial is an open-label study, and needs to include 40 patients (20 patients per group) and is expected to span 2 years. To our knowledge, this is the first randomized controlled trial to investigate the effects of DKT on postoperative subjective outcomes (i.e., postoperative quality of life) following laparoscopic colectomy as primary endpoints. Exploratory metabolomics analysis of metabolites in stool and blood will be conducted in this trial, which previously has

The aim of this study was to evaluate the effects of a traditional Chinese herbal medicine, dai-kenchu-to (DKT), on obstructive bowel diseases in children. We have treated 46 pediatric patients with various obstructive bowel diseases with DKT: six patients with postoperative ileus, 12 with large abdominal surgery (including three neonates), one with ano-rectal anomaly, three with Hirschsprung's disease, two with functional bowel obstructions, one with SMA syndrome, and 21 patients with chronic constipation. DKT (0.1-0.15 g/kg) was mixed with 5-10 ml of warm water, and was given orally two to three times a day. DKT was effective for 39 patients (85%) and their clinical symptoms improved. DKT was ineffective in seven patients: two with postoperative ileus, two with Hirschsprung's disease, and three with chronic constipation. DKT had mild but significant effects for various obstructive bowel diseases in children, while no side effects were encountered. Our current strategy for pediatric patients with obstructive bowel disease is to use DKT first and then test its efficacy. If DKT is effective, the regimen is continued. However, in cases where DKT is not effective, we will consider laparotomy or will further investigate the illness.

Survival after pancreatic head adenocarcinoma surgery is determined by tumor characteristics, resection margins, and adjuvant chemotherapy. Few studies have analyzed the long-term impact of postoperative morbidity. The aim of the present study was to assess the impact of postoperative complications on long-term survival after pancreaticoduodenectomy for cancer. Of 294 consecutive pancreatectomies performed between January 2000 and July 2011, a total of 101 pancreatic head resections for pancreatic ductal adenocarcinoma were retrospectively analyzed. Postoperative complications were classified on a five-grade validated scale and were correlated with long-term survival. Grade IIIb to IVb complications were defined as severe. Postoperative mortality and morbidity were 5 and 57 %, respectively. Severe postoperative complications occurred in 16 patients (16 %). Median overall survival was 1.4 years. Significant prognostic factors of survival were the N-stage of the tumor (median survival 3.4 years for N0 vs. 1.3 years for N1, p = 0.018) and R status of the resection (median survival 1.6 years for R0 vs. 1.2 years for R1, p = 0.038). Median survival after severe postoperative complications was decreased from 1.9 to 1.2 years (p = 0.06). Median survival for N0 or N1 tumor or after R0 resection was not influenced by the occurrence and severity of complications, but patients with a R1 resection and severe complications showed a worsened median survival of 0.6 vs. 2.0 years without severe complications (p = 0.0005). Postoperative severe morbidity per se had no impact on long-term survival except in patients with R1 tumor resection. These results suggest that severe complications after R1 resection predict poor outcome.

As the prevalence of obesity continues to increase, it now includes the growing number of patients with congenital heart disease (CHD). This particular obese patient population may pose additional intraoperative as well as postoperative challenges that may contribute to poor outcomes. Our aims were to determine the influence of obesity on morbidity and mortality in adults with CHD undergoing surgical repair at a free standing children's hospital. A retrospective analysis of adult (≥18 years) CHD surgery cases from 2002 to 2008 was performed. Congenital heart lesions were defined as mild, moderate, or complex. Patients were categorized by body mass index (BMI): underweight (BMI < 20 kg/m(2)), normal (BMI 20-24.9 kg/m(2)), overweight (BMI 25-29.9 kg/m(2)), and obese (BMI ≥ 30 kg/m(2)). Demographics, incidence of mortality, or specific morbidities were statistically compared using Fisher's exact test and analyses of variance (anovas). In this population (n = 165), overweight (29%) and obese (22%) patients were prevalent. Hypertension (HTN) and pre-HTN were more prevalent in obese and overweight patients. Postoperative renal dysfunction was observed in obese patients with complex CHD (P = .04). Mortality was not different among groups. Obesity is becoming increasingly common among adults with CHD. Despite marginal evidence of postoperative renal complications in obese patients with CHD of severe complexity, the overall presence of obesity did not influence mortality or short term postoperative morbidities. © 2011 Copyright the Authors.

Cancer developing from more than one origin is called multiple primary cancer (MPC) and is a rare situation. In this article, we report a case presenting to the Emergency Clinic with symptoms of ileus who was diagnosed with synchronous colon and breast cancer. A 57year old male patient presented to the Emergency Clinic with abdominal pain, vomiting, constipation and lack of flatulence. The patient was taken to the operating room for emergency surgery with the diagnosis of intestinal obstruction. While still hospitalized, breast ultrasound was performed, revealing a mass lesion in the right breast measuring 2cm. The core biopsy result was suggestive of invasive ductal adenocarcinoma. Right modified radical mastectomy with removal of the level 2 axillary lymph nodes was performed. The result of the histopathological investigation of the right hemicolectomy specimen was reported as moderately differentiated adenocarcinoma, while that of the mastectomy material was invasive ductal adenocarcinoma. Synchronous colorectal cancer is recognized as an important clinical entity, its clinical and pathological properties as well as prognosis are still undetermined. A family history of cancer might be a significant factor in synchronous cancers. Many of the theories about the etiology of multiple primary malignant neoplasia suggest the role of genetic, hormonal, environmental and immunological factors as well as iatrogenic causes. Especially for patients whose treatment begins in the emergency settings, meticulous systemic physical examination is recommended to initiate treatment of a possible synchronous tumor at an earlier stage.

A Comparative Study between the Effect of Combined Local Anesthetic and Low-dose Ketamine with Local Anesthetic on Postoperative Complications after Impacted Third Molar Surgery.

PubMed

Kumar, Anuj; Kale, Tejraj Pundalik

Postoperative pain, swelling and trismus are the most common outcome after third molar surgery. Many methods have been tried to improve postoperative comfort after surgery. Ketamine is a phencyclidine derivative that induces a state of dissociative anesthesia. It is a noncompetitive N-methyl-D-aspartate (NMDA) receptor antagonist and has a distinct suppression effect on central nervous system (CNS) sensitization. Ketamine in a subanesthetic dose is set to produce analgesic and anti-inflammatory effect. Sixty patients, between the age group of 18 and 38 years, undergoing the extraction of impacted mandibular third molar, reporting to the department of oral and maxillofacial surgery were included in the study. Patients were divided randomly into two groups: local anesthetic alone (LAA) and local anesthetic and ketamine (LAK). Statistical analysis was performed using the Mann-Whitney U/unpaired--t-test and Wilcoxon signed-rank test. There was a significant difference in mouth opening in the LAA and LAK group in the immediate postoperative period. There was a significant difference between the two groups after 1 hour (LAA: 2.37; LAK: 1.40), and 4 hours (LAA: 2.37; LAK: 1.40). There was a significant difference in terms of facial swelling in the immediate postoperative period and day 1 between the LAA and LAK group. Use of subanesthetic dose of ketamine is not only safe but also valuable in reducing patient morbidity after third molar surgery. Combination of a local anesthetic and subanesthetic dose of ketamine during surgical extraction of third molars provides good postoperative analgesia with less swelling and significantly less trismus.

Although revascularization surgery for patients with moyamoya disease can effectively prevent ischemic events and thus improve the long-term clinical outcome, the incidence of postoperative ischemic complications affects patients' quality of life. This study aimed to clarify the risk factors associated with postoperative ischemic complications and to discuss the appropriate perioperative management. Fifty-eight revascularization operations were performed in 37 children with moyamoya disease. Patients with moyamoya syndrome were excluded from this study. Magnetic resonance imaging was performed within 7 days after surgery. Postoperative cerebral infarction was defined as a diffusion-weighted imaging high-intensity lesion with or without symptoms. We usually use fentanyl and dexmedetomidine as postoperative analgesic and sedative drugs for patients with moyamoya disease. We used barbiturate coma therapy for pediatric patients with moyamoya disease who have all postoperative cerebral infarction risk factors. Postoperative ischemic complications were observed in 10.3% of the children with moyamoya disease (6 of 58). Preoperative cerebral infarctions (P = 0.0005), younger age (P = 0.038), higher Suzuki grade (P = 0.003), and posterior cerebral artery stenosis/occlusion (P = 0.003) were related to postoperative ischemic complications. Postoperative cerebral infarction occurred all pediatric patients using barbiturate coma therapy. The risk factors associated with postoperative ischemic complications for children with moyamoya disease are preoperative infarction, younger age, higher Suzuki grade, and posterior cerebral artery stenosis/occlusion. Barbiturate coma therapy for pediatric patients with moyamoya disease who have the previous risk factors is insufficient for prevention of postoperative cerebral infarction. More studies are needed to identify the appropriate perioperative management. Copyright © 2018 Elsevier Inc. All rights reserved.

Evaluation of diagnostic and treatment procedures in children with cystic fibrosis (CF) operated on because of meconium ileus (MI). The authors retrospectively reviewed the documentation of 10 CF newborn patients operated on in the years 2000-2014 because of MI. In prenatal ultrasound (US) examinations, suspicion of bowel abnormalities was raised in 2 cases, even though all the 10 mothers had a minimum of 3 US examinations during pregnancy. The mean gestational age of the newborns was 39.2 weeks - 36-41 weeks), their mean birth weight 3472g (2560-4550 g). Family history of CF was positive in two patients. Genetic testing was performed in all the children operated on. In all the children operated on, mutations in both alleles of the CFTR gene were found. Five patients were F508del homozygotic, 4 were heterozygotic for this mutation, one had another mutation. Sweat tests were positive in all the children. Abdominal distention was observed in 9 patients, vomiting and retention of gastric contents in 5. In 8 children meconium was not passed at all. 2 children passed a small amount of viscid meconium. Before the operation, rectal saline washouts were done in 5 newborns. Five patients were operated on during the first day of life, four on the second day and one on the third day of life. Intra-operatively a simple form of MI was diagnosed in 8 cases, a complicated form in 2 cases. In patients with the simple form of MI, a Bishop-Koop stoma was created after the evacuation of meconium. Two of these children needed a resection of some centimetres of dilated terminal ileum with doubtful viability. In newborns with the complicated form of MI, the treatment was individualized, always with stoma formation. The time of postoperative meconium evacuation through enterostomy ranged from 6 to 15 days. Enteral feeding was started on average on the 9th day postoperatively. The mean hospital stay was 22.9 days. In 8 children the stoma was taken out at the mean age of 19.4 months, in

To improve the surgical outcome of hypospadias repair surgery, preoperative hormonal stimulation (PHS) has been proposed. We conducted a meta-analysis to evaluate the impact of preoperative hormonal stimulation (PHS) treatment on complication rates following hypospadias repair surgery. A comprehensive literature search up to June 1st, 2015 was carried out for relevant studies. After literature identification and data extraction, relative ratio (RR) was calculated to compare postoperative complication rates. Heterogeneity among individual studies was tested using the Cochran χ2 Q test and quantified by calculating the I2 index. Meta-regression was applied to find potential affective factors. Overall, 428 patients from 6 studies had undergone primary hypospadias repair, of which 171 (39.95%) received some form of PHS with human chorionic gonadotropin (HCG), dihydrotestosterone (DHT) or testosterone (T). They underwent three different types of surgical techniques, including onlay island flap (N.=277), tubularized incised plate (N.=99) and Koyanagi urethroplasty (N.=52). These 6 studies classified the complication rates based on PHS. The relative ratio (RR) for a complication occurring following PHS use was 1.18 (95% CI: 0.70-2.00, Z=0.91, P=0.539). Significant heterogeneity (I2=47.1%, P=0.092) among various research literature was found and meta-regression was undertaken for the heterogeneity, but surgical technique, mean age of patients at time of surgery, types of PHS and the quality of studies were not the cause of heterogeneity. Use of T, DHT and HCG prior to hypospadias repair does not appear to increase the incidence of postoperative complications, but further investigation is needed.

Given the extent of the surgical indications for pulmonary lobectomy in breathless patients, preoperative care and evaluation of pulmonary function are increasingly necessary. The aim of this study was to assess the contribution of preoperative pulmonary rehabilitation (PR) for reducing the incidence of postoperative pulmonary complications in non-small cell lung cancer (NSCLC) patients with chronic obstructive pulmonary disease (COPD). The records of 116 patients with COPD, including 51 patients who received PR, were retrospectively analyzed. Pulmonary function testing, including slow vital capacity (VC) and forced expiratory volume in one second (FEV 1 ), was obtained preoperatively, after PR, and at one and six months postoperatively. The recovery rate of postoperative pulmonary function was standardized for functional loss associated with the different resected lung volumes. Propensity score analysis generated matched pairs of 31 patients divided into PR and non-PR groups. The PR period was 18.7 ± 12.7 days in COPD patients. Preoperative pulmonary function was significantly improved after PR (VC 5.3%, FEV 1 5.5%; P < 0.05). The FEV 1 recovery rate one month after surgery was significantly better in the PR (101.6%; P < 0.001) than in the non-PR group (93.9%). In logistic regression analysis, predicted postoperative FEV 1 , predicted postoperative %FEV 1 , and PR were independent factors related to postoperative pulmonary complications after pulmonary lobectomy (odds ratio 18.9, 16.1, and 13.9, respectively; P < 0.05). PR improved the recovery rate of pulmonary function after lobectomy in the early period, and may decrease postoperative pulmonary complications. © 2017 The Authors.

Adhesions after recurrent abdominal operations remain extremely common and are sources of severe morbidity. Fibrin-glued plication of the small gut in a meander-like formation is supposed to guarantee a decreased risk of intestinal obstruction postoperatively. This retrospective study analyses the clinical outcome after recurrent laparotomy in children treated with bowel plication by fibrin sealant. The surgical technique of performing the fibrin-glued plication is rather simple and quick: after taking off all adhesions two to four loops of the small gut are positioned so that they lie side by side. Beginning proximal fibrin [Tissucol fibrin sealant (Baxter)] is applied between the loops; approximately 20-30 s are needed to keep the loops in position until the fibrin dries. This manoeuvre is continued until all of the small gut is fixed in one block. The gut is brought back into the abdominal cavity without loosening the loops. This fixed formation by sero-serosal adhesions or mesenterial plications is supposed to guarantee postoperative free passage. The charts of 60 children who had undergone a fibrin plication of the small bowel between 1991 and 1999 were evaluated. Additionally, questionnaires were sent to all patients, and they were invited for an examination. Sixty patients (38 boys and 22 girls) received a fibrin sealant plication because of recurrent laparotomies with heavily serosal defects or recurrent ileus because of adhesions. The youngest baby was 10 days. Since 23 patients were premature the oldest patient was 11 years old. There were no intraoperative complications attributed to the method. In the postoperative period 7/60 (12%) patients had a recurrent ileus or subileus, leading in three (5%) patients to an early relaparotomy. The fibrin-glued plication of the small bowel decreases the risk of recurrent ileus or subileus considering the high figures in the literature concerning this issue. The time-saving method is very simple and easily feasible

In recent years, the use of laparoscopic techniques for surgical operations has been increasing, because this procedure is less invasive and is excellent in regard to patient's quality of life. Normally, complications are rare in laparoscopic surgery. However, we experienced a case of pulmonary embolism and one case of ileus as complications after laparoscopic radical prostatectomy. Especially, in this type of operation, the danger of complications is increased due to the severe head down and lithotomy position, which is employed to ensure a good view during operation. In this particular case, the long duration of operation may have been another related risk factor. There were no risk factors for pulmonary embolism such as those encountered when a patient is aged, obese, or bed ridden for a long time. However, an intermittent air massage must be applied to the lower legs to prevent thrombus due to poor blood circulation of the lower extremities below the knee during the surgery. It is also necessary to change the posture of the patient frequently after the operation. In addition, the administration of low molecular weight heparin may also be effective.

Removal of impacted third molar is a procedure that is often associated with post-operative complications. The rate of complications is somewhat high because of its proximity to the vital structures. Inferior alveolar nerve paresthesia is one of the common complications of impacted their molar surgery. This is due to intimate relationship between roots of mandibular third molar and inferior alveolar canal. To access the proximity of inferior alveolar canal to third molar many diagnostic methods are suggested but in conventional radiography orthopantamogram is considered as the best. There are many findings onorthopantamogram that are suggestive of close proximity of nerve to the canal. In this study authors reviewed seven radiographic findings related to proximity of roots to the inferior alveolar nerve as seen on orthopantamogram and try to find a relationship between these radiographic variables and presence of post-operative paresthesia. The study containd 100 impacted third molars need to be removed. Presence of radiographic findings on orthopantamogram were noted and analyzed, to find a relationship with occurrence of post-operative inferior alveolar nerve paresthesia. This study comprises of 100 impacted third molar teeth indicated for extraction. Cases were randomly selected from the patients, needs to undergo extraction of impacted mandibular third molar. After extraction cases were evaluated for occurrence of inferior alveolar nerve paresthesia. Stastical Analyisis: Data was transferred to SPss 21 software for frequency calculation, and two tailed p-values were obtained betweens these variables and post-operative paresthesia, by applying Fischer's exact test (GRAPH PAD SOFTWARE). Out of seven, four radiological findings that are grooving of roots, hooked roots, bifid roots and obliteration of white line are significantly related to post-operative paresthesia while bending of canal, narrow canal and darkening of tooth roots over the canal are not

Background To analyze the pre- and postoperative anxiety level in patients undergoing ambulatory oral surgery (AOS) in a primary healthcare center (PHC). Material and Methods Prospective and descriptive clinical study on 45 patients who underwent AOS procedures in the dental clinic of a public PHC of Spain between April and September 2015. Anxiety analysis was carried out with pre- and postoperative anxiety-state (STAI-S), anxiety-trait (STAI-T) and dental anxiety (MDAS) questionnaires. A descriptive, inferential and binary logistic regression analysis were performed for the variables age, sex, educational level, previous experience of oral treatment, type of oral surgery, degree of third molar impaction, surgical time, intraoperative complications, postoperative complications, and pain score with a visual analogue scale (VAS). Results The majority were female (57.8%) with a mean age of 33.5+9.6 years. The most frequent procedure was the lower third molar removal (82.2%). The mean pain score on the VAS was 1.6+1.8. The incidence of complications was low (7.8%). There was a statistically significant association between post- and preoperative anxiety (r=0.56, p<0.001) and a correlation between pain score and postoperative anxiety (Rho= -0.35, p=0.02). The likelihood of postoperative anxiety was related to preoperative anxiety (OR=1.3, p=0.03). Conclusions AOS in a HPC is safe and should be more encouraged in the public primary care. The emotional impact on users was relatively low, highlighting that the preoperative anxiety levels were higher than the postoperative ones. Psychological factors related to pre- and postoperative anxiety should be considered in the AOS carried out in PC. Key words:Anxiety, oral surgery, ambulatory surgery, primary care, STAI scale, postoperative pain. PMID:29053655

Purpose Emergency operations for perforated peptic ulcer are associated with a high incidence of postoperative complications. While several studies have investigated the impact of perioperative risk factors and underlying diseases on the postoperative morbidity after abdominal surgery, only a few have analyzed their role in perforated peptic ulcer disease. The purpose of this study was to determine any possible associations between postoperative morbidity and comorbid disease or perioperative risk factors in perforated peptic ulcer. Materials and Methods In total, 142 consecutive patients, who underwent surgery for perforated peptic ulcer, at a single institution, between January 2005 and October 2010 were included in this study. The clinical data concerning the patient characteristics, operative methods, and complications were collected retrospectively. Results The postoperative morbidity rate associated with perforated peptic ulcer operations was 36.6% (52/142). Univariate analysis revealed that a long operating time, the open surgical method, age (≥60), sex (female), high American Society of Anesthesiologists (ASA) score and presence of preoperative shock were significant perioperative risk factors for postoperative morbidity. Significant comorbid risk factors included hypertension, diabetes mellitus and pulmonary disease. Multivariate analysis revealed a long operating time, the open surgical method, high ASA score and the presence of preoperative shock were all independent risk factors for the postoperative morbidity in perforated peptic ulcer. Conclusions A high ASA score, preoperative shock, open surgery and long operating time of more than 150 minutes are high risk factors for morbidity. However, there is no association between postoperative morbidity and comorbid disease in patients with a perforated peptic ulcer. PMID:22500261

Cognitive dysfunctions are relatively common in postoperative and critically ill patients. This complication not only compromises recovery after surgery, but, if persistent, it minimizes and compromises surgery itself. Risk factors of postoperative cognitive disorders can be divided into age and comorbidity dependent, and those related to anesthesia and surgery. Cardiovascular, orthopedic and urologic surgery carries high risk of postoperative cognitive dysfunction. It can also occur in other types of surgical treatment, especially in elderly. Among risk factors of cognitive disorders, associated with comorbidity, underlying psychiatric and neurological disorders, substance abuse and conditions with elevation of intracranial pressure are in the first place in postoperative patients. Preoperative and perioperative predisposing conditions for cognitive dysfunction and their incidence were described in our paper. These are: geriatric patients, patients with substance abuse, preexisting psychiatric or cognitive disorders, neurologic disease with high intracranial pressure, cerebrovascular insufficiency, epilepsia, preeclampsia, acute intermittent porphyria, operation type, brain hypoxia, changes in blood glucose level, electrolyte imbalance, anesthetic agents, adjuvant medication and intraoperative awareness. For each of these factors, evaluation, prevention and treatment strategies were suggested, with special regard on anesthetic technique.

Thoraco-lumbar posterior fusion surgery is a frequent procedure used for patients with spinal instability due to tumor, trauma or degenerative disease. In the perioperative phase, many patients may experience vomiting, bowel irritation, constipation, or may even show symptoms of adynamic ileus possibly due to immobilization and high doses of opioid analgesics and narcotics administered during and after surgery. Retrospective single-center study on patients undergoing thoraco-lumbar fusion surgery for degenerative lumbar spine disease with instability in 2012. Study groups were built according to presence/absence of postoperative constipation, with postoperative constipation being defined as no bowel movement on postoperative days 0-2. Ninety-nine patients (39 males, 60 females) with a mean age of 57.1 ± 17.3 years were analyzed, of which 44 patients with similar age, gender, BMI and ASA-grades showed constipation (44.4%). Occurrence of constipation was associated with longer mean operation times (247 ± 62 vs. 214 ± 71 min; p=0.012), higher estimated blood loss (545 ± 316 vs. 375 ± 332 ml; p<0.001), and higher mean morphine dosages in the postoperative days 0-7 (the difference being significant on postoperative days 1 (48 mg vs. 30.9 mg, p=0.041) and 2 (43.2mg vs. 29.1mg, p=0.028). The equivalence dose of morphine administered during surgery was similar (339 ± 196 vs. 285 ± 144 mg; p=0.286). The use of laxatives in the postoperative days 0-7 was generally high in both study groups, while it was more frequent in patients experiencing constipation. One patient with constipation developed a sonographically confirmed paralytic ileus. Patients with constipation showed a tendency toward longer postoperative hospitalization (7.6 vs. 6.7 days, p=0.136). The rate of constipation was high after thoraco-lumbar fusion surgery. Moreover, it was associated with longer surgery time, higher blood loss, and higher postoperative morphine doses. Further trials are needed to

Background Postoperative pleural drainage markedly influences the length of postoperative stay and financial costs of medical care. The aim of this study is to retrospectively investigate potentially predisposing factors related to pleural drainage after curative thoracic surgery and to explore the impact of mediastinal micro-vessels clipping on pleural drainage control after lymph node dissection. Methods From February 2012 to November 2013, 322 consecutive cases of operable non-small cell lung cancers (NSCLC) undergoing lobectomy and mediastinal lymph node dissection with or without application of clipping were collected. Total and daily postoperative pleural drainage were recorded. Propensity score matching (1:2) was applied to balance variables potentially impacting pleural drainage between group clip and group control. Analyses were performed to compare drainage volume, duration of chest tube and postoperative hospital stay between the two groups. Variables linked with pleural drainage in whole cohort were assessed using multivariable logistic regression analysis. Results Propensity score matching resulted in 197 patients (matched cohort). Baseline patient characteristics were matched between two groups. Group clip showed less cumulative drainage volume (P=0.020), shorter duration of chest tube (P=0.031) and postoperative hospital stay (P=0.022) compared with group control. Risk factors significantly associated with high-output drainage in multivariable logistic regression analysis were being male, age >60 years, bilobectomy/sleeve lobectomy, pleural adhesion, the application of clip applier, duration of operation ≥220 minutes and chylothorax (P<0.05). Conclusions This study suggests that mediastinal micro-vessels clipping during lymph node dissection may reduce postoperative pleural drainage and thus shorten hospital stay. PMID:27076936

Objective To evaluate the effect of preoperative anaemia and blood transfusion on 30-day postoperative morbidity and mortality in patients undergoing gynecological surgery. Study Design Data were analyzed from 12,836 women undergoing operation in the American College of Surgeons National Surgical Quality Improvement Program. Outcomes measured were; 30-day postoperative mortality, composite and specific morbidities (cardiac, respiratory, central nervous system, renal, wound, sepsis, venous thrombosis, or major bleeding). Multivariate logistic regression models were performed using adjusted odds ratios (ORadj) to assess the independent effects of preoperative anaemia (hematocrit <36.0%) on outcomes, effect estimates were performed before and after adjustment for perioperative transfusion requirement. Results The prevalence of preoperative anaemia was 23.9% (95%CI: 23.2–24.7). Adjusted for confounders by multivariate logistic regression; preoperative anaemia was independently and significantly associated with increased odds of 30-day mortality (OR: 2.40, 95%CI: 1.06–5.44) and composite morbidity (OR: 1.80, 95%CI: 1.45–2.24). This was reflected by significantly higher adjusted odds of almost all specific morbidities including; respiratory, central nervous system, renal, wound, sepsis, and venous thrombosis. Blood Transfusion increased the effect of preoperative anaemia on outcomes (61% of the effect on mortality and 16% of the composite morbidity). Conclusions Preoperative anaemia is associated with adverse post-operative outcomes in women undergoing gynecological surgery. This risk associated with preoperative anaemia did not appear to be corrected by use of perioperative transfusion. PMID:26147954

OBJECTIVE Lumbar epidural steroid injections (LESIs) are performed for both diagnostic and therapeutic purposes for a variety of indications, including low-back pain, the leading cause of disability and expense due to work-related conditions in the US. The steroid agent used in epidural injections is reported to relieve nerve root inflammation, local ischemia, and resultant pain, but the injection may also have an adverse impact on spinal surgery performed thereafter. In particular, the possibility that preoperative epidural injections may increase the risk of surgical site infection after lumbar spinal fusion has been reported but has not been studied in detail. The goal of the present study was to use a large national insurance database to analyze the association of preoperative LESIs with surgical site infection after lumbar spinal fusion. METHODS A nationwide insurance database of patient records was used for this retrospective analysis. Current Procedural Terminology codes were used to query the database for patients who had undergone LESI and 1- or 2-level lumbar posterior spinal fusion procedures. The rate of postoperative infection after 1- or 2-level posterior spinal fusion was analyzed. These study patients were then divided into 3 separate cohorts: 1) lumbar spinal fusion performed within 1 month after LESI, 2) fusion performed between 1 and 3 months after LESI, and 3) fusion performed between 3 and 6 months after LESI. The study patients were compared with a control cohort of patients who underwent lumbar fusion without previous LESI. RESULTS The overall 3-month infection rate after lumbar spinal fusion procedure was 1.6% (1411 of 88,540 patients). The infection risk increased in patients who received LESI within 1 month (OR 2.6, p < 0.0001) or 1-3 months (OR 1.4, p = 0.0002) prior to surgery compared with controls. The infection risk was not significantly different from controls in patients who underwent lumbar fusion more than 3 months after LESI

Background Hypocalcemia occurs after total thyroidectomy (TT) for Graves’ disease via parathyroid injury and/or from increased bone turnover. Current management is to supplement calcium after surgery. This study evaluates the impact of preoperative calcium supplementation on hypocalcemia after Graves’ TT. Methods A prospective study of Graves’ patients undergoing TT was performed. Graves’ patients managed over a 9 month period took 1gm of calcium carbonate (CC) three times a day for two weeks before TT. Those managed the previous year, without supplementation served as historic controls. Age-, gender-, and thyroid weight-matched, non-Graves’ TT patients were procedure controls. Patient demographics, postoperative laboratory values, complaints and medications were reviewed. PTH based postoperative protocols dictated postoperative CC and calcitriol use. Results 45 Graves’ patients were treated with CC before TT, while 38 Graves’ patients were not. 40 non-Graves’ controls were identified. Age, gender and thyroid weight were comparable. Pre-operative calcium and PTH levels were equivalent. PTH values immediately after surgery, POD 1 and at 2 week follow-up were equivalent. Post-operative use of scheduled CC(p=0.10) and calcitriol(p=0.60) was similar. Post-operatively, untreated Graves’ had lower serum calcium levels than pre-treated Graves’ or non-Graves’ controls(8.3mg/dL vs. 8.6 vs. 8.6, p=0.05). Complaints of numbness and tingling were more common in non-treated Graves’(26%) than pretreated Graves’(9%) or non-Graves’ controls(10%, p<0.05). Conclusions Calcium supplementation before TT for Graves’ significantly reduced biochemical and symptomatic postoperative hypocalcemia. Preoperative calcium supplementation is a simple treatment that can reduce symptoms of hypocalcemia after Graves’ TT. PMID:25212835

To determine the impact of preoperative serum creatinine level in non-dialyzable patients on postoperative morbidity and mortality. This is a prospective study, where serum creatinine was used to give primary assessment on renal function status preoperatively. This study includes 1,033 patients, who underwent coronary artery bypass grafting, or valve(s) operations. The study took place at Al-Hada Military Hospital, Taif, Kingdom of Saudi between May 2008 and January 2012. Data were statistically analyzed using Chi square (x2) test and multivariable logistic regression, to evaluate the postoperative morbidity and mortality risks associated with low serum creatinine levels. Postoperative mortality increased with high serum creatinine level >1.8 mg/dL (ppostoperative renal failure, prolonged ventilatory support, ICU stay, and total hospital stay. Perioperative serum creatinine is strongly related to post operative morbidity and mortality in open heart surgery. High serum creatinine in non-dialyzable patients can predict the increased morbidity and mortality after cardiac operations.

Clinical stage II/III esophageal cancer (EC), as defined by the Japanese Classification, relapses at a moderately high rate even after curative resection. The number of lymph node metastases is known to be associated with tumor relapse. Recently, the prognostic significance of occult metastatic lymph nodes (MLNs), as well as that of overt MLNs, has been reported. The aim of this study was to investigate the impact of the total number of MLNs including occult MLNs on postoperative relapse in clinical stage II/III EC. One hundred and five patients with clinical stage II/III EC who underwent esophagectomy accompanied by radical lymphadenectomy at the Department of Surgical Oncology in Osaka City University Hospital between January 2000 and October 2008 were included in this study. Occult MLNs, metastases not detected by hematoxylin-eosin staining, were identified by immunohistochemistry (IHC) using antipancytokeratin antibody AE1/AE3. The clinicopathological features of occult MLNs were compared between the relapse and no relapse groups. A total of 6558 lymph nodes (1357 from two-field dissection and 5201 from three-field dissection) were examined by IHC staining; 362 overt MLNs and 143 occult MLNs were detected. The number of occult MLNs increased in proportion to the International Union Against Cancer pathological (p)N-status and pStage. When the number of occult MLNs was added to the number of pNs, the number of total MLNs was associated with postoperative relapse. With respect to tumor, node, metastasis stage, 6 of 22 patients (27%) who were pathological node-negative converted to node-positive by considering total MLNs. The number of N3 patients with relapse increased markedly with restaging by total MLNs. The number of total MLNs, but not overt MLNs, was an independent prognostic factor on multivariate analysis. These results suggest that occult MLNs were often found, and they were associated with postoperative relapse of resectable esophageal cancer. The total

Background Microvascular decompression (MVD) is a surgical treatment for cranial nerve disorders via a small craniotomy. The postoperative pain of this procedure can be classified as surgical site somatic pain and postcraniotomy headache similar in nature to a migraine, including its association with photophobia, nausea, and vomiting. This headache can be difficult to treat and can impact on postoperative recovery. Sumatriptan is used to treat migraine-like headaches in various settings. This single-centre randomized controlled trial investigated whether postoperative administration of sumatriptan after MVD surgery impacts the quality of postoperative recovery. Methods Fifty patients who complained of postoperative headache after MVD were randomized to receive an s.c. injection of sumatriptan (6 mg) or saline. The primary outcome was quality of recovery as measured by the Quality of Recovery-40 (QoR-40) score at 24 h. Results The QoR-40 scores were significantly higher in the sumatriptan group (median 184; interquartile range 169–196) than in the placebo group (133; 119–155; P<0.01), suggesting higher quality of recovery. The sumatriptan group also had significantly lower headache scores at 4, 12, and 24 h. There were no significant differences in other secondary outcomes. Conclusions Use of sumatriptan improved the quality of recovery as measured by the QoR-40 and reduction of headache at 24 h after surgery. Sumatriptan is a useful alternative treatment for postcraniotomy headache. The mechanism remains unknown but could be related to reduction in headache, mood modulation, or both, mediated by a serotonin effect. Clinical trial registration NCT01632657. PMID:27317706

Abdominal surgery represents a physiologic stress and is associated with a period of recovery during which functional capacity is often diminished. "Prehabilitation" is a program to increase functional capacity in anticipation of an upcoming stressor. We reported recently the results of a randomized trial comparing 2 prehabilitation programs before colorectal surgery (stationary cycling plus weight training versus a recommendation to increase walking coupled with breathing exercises); however, adherence to the programs was low. The objectives of this study were to estimate: (1) the extent to which physical function could be improved with either prehabilitation program and identify variables associated with response; and (2) the impact of change in preoperative function on postoperative recovery. This study involved a reanalysis of data arising from a randomized trial. The primary outcome measure was functional walking capacity measured by the Six-Minute Walk Test; secondary outcomes were anxiety, depression, health-related quality of life, and complications (Clavien classification). Multiple linear regression was used to estimate the extent to which key variables predicted change in functional walking capacity over the prehabilitation and follow-up periods. We included 95 people who completed the prehabilitation phase (median, 38 days; interquartile range, 22-60), and 75 who were also evaluated postoperatively (mean, 9 weeks). During prehabilitation, 33% improved their physical function, 38% stayed within 20 m of their baseline score, and 29% deteriorated. Among those who improved, mental health, vitality, self-perceived health, and peak exercise capacity also increased significantly. Women were less likely to improve; low baseline walking capacity, anxiety, and the belief that fitness aids recovery were associated with improvements during prehabilitation. In the postoperative phase, the patients who had improved during prehabilitation were also more likely to have

Background: Systematic screening and treatment of sleep-disordered breathing (SDB) or obstructive sleep apnea (OSA) in presurgical patients would impose a significant cost burden; therefore, it is important to understand whether SDB is associated with worse postoperative outcomes. We sought to determine the impact of SDB on postoperative outcomes in patients undergoing four specific categories of elective surgery (orthopedic, prostate, abdominal, and cardiovascular). The primary outcomes were in-hospital death, total charges, and length of stay (LOS). Two secondary outcomes of interest were respiratory and cardiac complications. Methods: Data were obtained from the Nationwide Inpatient Sample database. Regression models were fitted to assess the independent association between SDB and the outcomes of interest. Results: The cohort included 1,058,710 hospitalized adult patients undergoing elective surgeries between 2004 and 2008. SDB was independently associated with decreased mortality in the orthopedic (OR, 0.65; 95% CI, 0.45-0.95; P = .03), abdominal (OR, 0.38; 95% CI, 0.22-0.65; P = .001), and cardiovascular surgery groups (OR, 0.54; 95% CI, 0.40-0.73; P < .001) but had no impact on mortality in the prostate surgery group. SDB was independently associated with a small, but statistically significant increase in estimated mean LOS by 0.14 days (P < .001) and estimated mean total charges by $860 (P < .001) in the orthopedic surgery group but was not associated with increased LOS or total charges in the prostate surgery group. In the abdominal and cardiovascular surgery groups, SDB was associated with a significant decrease in adjusted mean LOS of 1.1 days and 0.35 days, respectively (P < .001 for both groups), and adjusted mean total charges of $3,814 and $4,592, respectively (P < .001 for both groups). SDB was independently associated with a significantly increased OR for emergent intubation and mechanical ventilation, noninvasive ventilation, and atrial

To evaluate the impact of hypocaloric and hypo-nitrogen parenteral nutrition (PN) on infective complication rate, postoperative hospital stay and treatment cost in postoperative period. 120 patients with gastrointestinal tumors with the Nutrition Risk Screening (NRS) score of 3 or 4 undergoing radical gastrectomy in 5 hospitals were randomly assigned into 2 equal groups: control group, receiving PN with 30 (28 - 32) kcal x kg(-1) x d(-1) and nitrogen 0.20 (0.19 - 0.21) g x kg(-1) x d(-1) in regular "3 liter bag", and study group receiving calorie of 18 (range 16 - 20) kcal x kg(-1) x d(-1) and nitrogen of 0.10 (0.09 - 0.11) g x kg(-1) x d(-1) with triple chamber bag. PN support was infused continuously for at least six postoperative days through peripheral vein or peripherally inserted central catheter. The differences between these two groups in blood glucose level, infectious complication, phlebitis, systemic inflammatory response syndrome (SIRS), and duration of hospital stay after operation, and treatment cost. All data were evaluated by both intention to treat (ITT) analysis and per protocol (PP) analysis. There were no significant differences in the clinical baseline and operative types between the two groups. ITT analysis showed that the occurrence of hyperglycemia in postoperative period in the control group was 43.3%, significantly much higher than that in the study group (6.6%, P = 0.000). The infectious complication rate of the study group was 3.3%, significantly lower than that of the control group (16.6%, P = 0.0149), the phlebitis rate of the study group was 0.0%, significantly lower than that of the control group (18.3%, P = 0.0005). The SIRS rate of the study group was 25.0%, significantly lower than that of the control group (45.0%, P = 0.0216). PP analysis showed that the postoperative duration of hospital stay of the control group was 14.1 days +/- 5.8 days, significantly longer than that of the study group (12.4 days +/- 4.0 days, P = 0

The number of geriatric patients with esophageal cancer is increasing in step with the aging of the population. Geriatric patients have a higher risk of postoperative complications, including delirium that can cause a fall or impact survival. Therefore, it is very important that we evaluate risks of postoperative complications before surgery. The aim of this study was to predict postoperative delirium in elderly patients. We retrospectively reviewed the medical records of 91 patients aged 75 years and over who underwent esophagectomy between January 2006 and December 2014. We investigated the association between postoperative delirium and clinicopathological factors, including comprehensive geriatric assessment (CGA). Postoperative delirium developed in 24 (26 %) patients. Postoperative delirium was significantly associated with low mini-mental state examination (MMSE) and high Geriatric Depression Scale 15 (GDS15), which are components of CGA, and psychiatric disorder (P < 0.0001, P = 0.002, and P = 0.017, respectively). With multiple logistic regression analysis, MMSE (odds ratio [OR], 1.4; 95 % confidence interval [CI], 1.2-1.6; P < 0.0001] and GDS15 (OR, 1.3; 95 % CI, 1.1-1.6; P = 0.004) were independently associated with postoperative delirium. Preoperative CGA, especially MMSE and GDS15, was useful for predicting postoperative delirium in elderly patients undergoing esophagectomy for esophageal cancer. Intervention by a multidisciplinary team using CGA might help prevent postoperative delirium.

Few studies have addressed the role of residents' participation in morbidity and mortality after orthopaedic surgery. The present study utilized the 2005-2010 National Surgical Quality Improvement Program (NSQIP) dataset to assess the risk of 30-day post-operative complications and mortality associated with resident participation in orthopaedic procedures. The NSQIP dataset was queried using codes for 12 common orthopaedic procedures. Patients identified as having received one of the procedures had their records abstracted to obtain demographic data, medical history, operative time, and resident involvement in their surgical care. Thirty-day post-operative outcomes, including complications and mortality, were assessed for all patients. A step-wise multivariate logistic regression model was constructed to evaluate the impact of resident participation on mortality- and complication-risk while controlling for other factors in the model. Primary analyses were performed comparing cases where the attending surgeon operated alone to all other case designations, while a subsequent sensitivity analysis limited inclusion to cases where resident participation was reported by post-graduate year. In the NSQIP dataset, 43,343 patients had received one of the 12 orthopaedic procedures queried. Thirty-five percent of cases were performed with resident participation. The mortality rate, overall, was 2.5 and 10 % sustained one or more complications. Multivariate analysis demonstrated a significant association between resident participation and the risk of one or more complications [OR 1.3 (95 % CI 1.1, 1.4); p < 0.001] as well as major systemic complications [OR 1.6 (95 % CI 1.3, 2.0); p < 0.001] for primary joint arthroplasty procedures only. These findings persisted even after sensitivity testing. A mild to moderate risk for complications was noted following resident involvement in joint arthroplasty procedures. No significant risk of post-operative morbidity or mortality was

Background Although circumcision for phimosis in children is a minor surgical procedure, it is followed by pain and carries the risk of increased postoperative anxiety. This study examined predictive factors of postoperative pain and anxiety in children undergoing circumcision. Methods We conducted a prospective cohort study of children scheduled for elective circumcision. Circumcision was performed applying one of the following surgical techniques: sutureless prepuceplasty (SP), preputial plasty technique (PP), and conventional circumcision (CC). Demographics and base-line clinical characteristics were collected, and assessment of the level of preoperative anxiety was performed. Subsequently, a statistical model was designed in order to examine predictive factors of postoperative pain and postoperative anxiety. Assessment of postoperative pain was performed using the Faces Pain Scale (FPS). The Post Hospitalization Behavior Questionnaire study was used to assess negative behavioral manifestations. Results A total of 301 children with a mean age of 7.56 ± 2.61 years were included in the study. Predictive factors of postoperative pain measured with the FPS included a) the type of surgical technique, b) the absence of siblings, and c) the presence of postoperative complications. Predictive factors of postoperative anxiety included a) the type of surgical technique, b) the level of education of mothers, c) the presence of preoperative anxiety, and d) a history of previous surgery. Conclusions Although our study was not without its limitations, it expands current knowledge by adding new predictive factors of postoperative pain and postoperative anxiety. Clearly, further randomized controlled studies are needed to confirm its results. PMID:26495079

A 63-year-old woman with abdominal pain was referred to our hospital. Her pancreatic enzymes were elevated, and an abdominal computed tomography (CT) scan showed an enlarged pancreas, consistent with pancreatitis, and gas collection containing an impacted stone adjacent to Vater's papilla. This finding raised the suspicion of a duodenal diverticulum. A subsequent ERCP showed a juxtapapillary duodenal diverticulum (JPDD) filled with calculi and pus. The pancreatitis improved with 2 weeks of conservative treatment. Subsequently, the patient underwent resection of the uterus and bilateral adnexa to remove a large ovarian cyst that was also identified on the admission CT scan. On the third postoperative day, she developed abdominal pain and vomiting. CT revealed small bowel obstruction caused by an enterolith expelled from JPDD. Enterotomy was performed to remove the stone. To our knowledge, only three similar cases have been previously reported in Japan.

Postoperative peritonitis is still a life-threatening complication after abdominal surgery and approximately 10,000 patients annually develop postoperative peritonitis in Germany. Early recognition and diagnosis before the onset of sepsis has remained a clinical challenge as no single specific screening test is available. The aim of therapy is a rapid and effective control of the source of infection and antimicrobial therapy. After diagnosis of diffuse postoperative peritonitis surgical revision is usually inevitable after intestinal interventions. Peritonitis after liver, biliary or pancreatic surgery is managed as a rule by means of differentiated therapy approaches depending on the severity.

The impact of anesthetic choice on postoperative mortality and morbidity has not been determined with certainty. The authors evaluated the effect of type of anesthesia on postoperative mortality and morbidity in a retrospective cohort study of consecutive hip fracture patients, aged 60 yr or older, who underwent surgical repair at 20 US hospitals between 1983 and 1993. The primary outcome was defined as death within 30 days of the operative procedure. The secondary outcomes were postoperative 7-day mortality, postoperative myocardial infarction, postoperative pneumonia, postoperative congestive heart failure, and postoperative change in mental status. Numerous comorbid conditions were controlled for individually and by several comorbidity indices using logistic regression. General anesthesia was used in 6,206 patients (65.8%) and regional anesthesia in 3,219 patients (3,078 spinal anesthesia and 141 epidural anesthesia). The 30-day mortality rate in the general anesthesia group was 4.4%, compared with 5.4% in the regional anesthesia group (unadjusted odds ratio = 0.80; 95% confidence interval = 0.66-0.97). However, the adjusted odds ratio for general anesthesia increased to 1.08 (0.84-1.38). The adjusted odds ratios for general anesthesia versus regional anesthesia for the 7-day mortality was 0.90 (0.59-1.39) and for postoperative morbidity outcomes were as follows: myocardial infarction: adjusted odds ratio = 1.17 (0.80-1.70); congestive heart failure: adjusted odds ratio = 1.04 (0.80-1.36); pneumonia: adjusted odds ratio = 1.21 (0.87-1.68); postoperative change in mental status: adjusted odds ratio = 1.08 (0.95-1.22). The authors were unable to demonstrate that regional anesthesia was associated with better outcome than was general anesthesia in this large observational study of elderly patients with hip fracture. These results suggest that the type of anesthesia used should depend on factors other than any associated risks of mortality or morbidity.

To compare the efficacy of preoperative submucosal injection of 4 mg of dexamethasone versus 40 mg of methylprednisolone in reducing postoperative sequelae after surgical removal of impacted mandibular third molars. This prospective, randomized, double-blind study included 65 patients who required surgical removal of impacted mandibular third molars with Class II or position B impaction (Pell and Gregory classification). Patients were randomly assigned to 1 of 3 groups: dexamethasone, methylprednisolone, or placebo (control). Surgery was performed with patients under local anesthesia. Baseline measurements were obtained preoperatively, and subsequent assessments were made on postoperative day 1, 2, 5, and 7 to measure postoperative facial swelling by use of 2 linear measurements: interincisal mouth opening width and visual analog scale score for pain. The amount of analgesics consumed was recorded. Wound healing also was assessed on postoperative day 7. Descriptive and multivariate statistics were computed, and significance was set at P < .05. Both methylprednisolone and dexamethasone significantly reduced swelling and trismus (P < .05, Kruskal-Wallis test), whereas the methylprednisolone group had significantly less pain (P < .05, Kruskal-Wallis test) and consumed a lower amount of analgesics (P < .05, χ 2 test) during the early postoperative days. The study findings suggest that a single preoperative dose of dexamethasone versus methylprednisolone was equally effective in reducing postoperative swelling and trismus. Pain control by these corticosteroids, however, was variable. Copyright © 2017 American Association of Oral and Maxillofacial Surgeons. Published by Elsevier Inc. All rights reserved.

This study measured the tip-apex distance (TAD) values in the immediate postoperative period and following weight-bearing and fracture impaction in patients undergoing osteosynthesis with dynamic hip screw and cephalomedullary nail. To correlate the Baumgaertner index in the immediate postoperative period with values obtained after impaction of the fracture with the accommodation of the cephalic implant in the femoral head. Radiographic TAD measurements were taken with AGFA-VIEW ® of 82 patients with a mean age of 72 years with pertrochanteric fractures who were operated on and the fracture fixed with DHS- Synthes ® , TFN-Synthes ® , or Gamma Nail III-Stryker ® in the immediate postoperative period, and following weight-bearing and fracture impaction (mean 3-8 weeks after surgery). The overall average TAD decreased from 20.3mm to 18.2mm. Regardless of the instability of the fracture, the age of the patient or the implant used, TAD decreased between the immediate postoperative period and following fracture impaction. The osteosynthesis of pertrochanteric fractures was associated with important accommodation of the cephalic implant in the femoral head with decreased TAD values after weight-bearing. © 2017 Elsevier Ltd.

The benefits of early enteral feeding (EEN) have been demonstrated in gastrointestinal surgery. But, the impact of EEN has not been elucidated yet. We assessed the postoperative nutritional status of patients who had undergone pancreaticoduodenectomy (PD) according to the postoperative nutritional method and compared the clinical outcomes of two methods. A prospective randomized trial was undertaken following PD. Patients were randomly divided into two groups; the EEN group received the postoperative enteral feed and the control group received the postoperative total parenteral nutrition (TPN) management. Thirty-eight patients were included in our analyses. The first day of bowel movement and time to take a normal soft diet was significantly shorter in EEN group than in TPN group. Prealbumin and transferrin were significantly reduced on post-operative day (POD) 7 and were slowly recovered until POD 90 in the TPN group than in the EEN group. EEN group rapidly recovered weight after POD 21 whereas it was gradually decreased in TPN group until POD 90. EEN after PD is associated with preservation of weight compared with TPN and impact on recovery of digestive function after PD. PMID:22379336

Primary aldosteronism causes hypertension and hypokalemia and is often surgically treatable. Diagnosis includes elevated plasma aldosterone, suppressed plasma renin activity, and elevated aldosterone renin ratio. Adrenalectomy improves hypertension and hypokalemia. Postoperative plasma aldosterone and plasma renin activity may be useful in documenting cure or failure. A retrospective analysis of patients who underwent adrenalectomy for primary aldosteronism from 2010 to 2016 was performed, analyzing preoperative and postoperative plasma aldosterone, plasma renin activity, hypertension, and hypokalemia. The utility of postoperative testing was assessed. Clinical cure was defined as improved hypertension control and resolution of potassium loss. Biochemical cure was defined as aldosterone renin ratio reduction to <23.6. Forty-four patients were included; 20 had plasma aldosterone and plasma renin activity checked on postoperative day 1. In the study, 40/44 (91%) were clinically cured. All clinical failures had of biochemical failure at follow-up. Postoperative day 1aldosterone renin ratio <23.6 had PPV of 95% for clinical cure. Cured patients had mean plasma aldosterone drop of 33.1 ng/dL on postoperative day 1; noncured patient experienced 3.9 ng/dL increase. A cutoff of plasma aldosterone decrease of 10 ng/dL had high positive predictive value for clinical cure. Changes in plasma aldosterone and plasma renin activity after adrenalectomy correlate with improved hypertension and hypokalemia. The biochemical impact of adrenalectomy manifests as early as postoperative day 1. We propose a plasma aldosterone decrease of 10 ng/dL as a criterion to predict clinical cure.

To understand parents' experiences of managing their child's postoperative pain at home. Recent changes in children's health care services often shift the responsibility of managing children's postoperative pain to parents. Although pain management is important for good postoperative outcomes, it can be a challenging task for families, and children's pain is often under-managed. This qualitative study used semi-structured interviews to explore parents' experiences of managing their child's postoperative pain at home. Participants were parents of 10 typically developing 5- and 6-year olds, who underwent (adeno)tonsillectomy, and experienced no complications leading to hospitalisation in the postoperative period. One-on-one interviews were conducted with parents within three months of their child's surgery. Interviews were transcribed verbatim and content analysis was used to identify themes in parents' experiences. All children experienced some postoperative pain. Parents' experiences of managing their child's pain were impacted by balancing the pros and cons of administering analgesic medications, managing the emotional and psychological effects of their child's pain, as well as parents' information needs. Most parents' information needs were met yet they still struggled to manage their child's pain. These findings provide insight into some of the barriers that make this process challenging for many families, and what health care centres can do to help support parents manage their child's postoperative pain at home. The results of this study may aid in the design of interventions that will support parents when managing their child's postoperative pain at home and thus improve children's experiences. © 2016 John Wiley & Sons Ltd.

Universal postoperative guidelines for cataract extraction surgery are yet to be introduced. Artificial tears are gaining popularity as an additional integral component of the postoperative regime. The primary objective of this study was to explore the impact of two prevalent artificial tear preparations on postoperative discomfort following cataract extraction surgery. A total of 180 patients that underwent cataract extraction surgery were randomly divided into three groups according to their postoperative regime: a) Study group 1 (SG1) received a fixed combination of tobramycin and dexamethasone (FCTD) quid for 3 weeks and, additionally polyethylene glycol 400/propylene glycol/hydroxypropyl-guar quid, for 6 weeks, b) Study group 2 (SG2) received FCTD quid for 3 weeks and, additionally 0.1% sodium hyaluronate provided in the COMOD® device quid, for 6 weeks, and, c) Control Group (CG) received only FCTD quid for 3 weeks. The following indexes were evaluated at three postoperative checkpoints: 1) Subjective discomfort index (SDI) derived from four direct 10-scale Likert-type questions that were addressed to the patient and pertained to: a) foreign body sensation (FBS), b) blinking discomfort (BD), c) stinging sensation (SS), d) tearing sensation (TS), 2) Tear break-up time (TBUT), 3) Central corneal thickness (CCT) and, 4) Central Corneal Sensitivity (CCS). Both groups showed increased CCT values at the first examination point and reduced CCS values at all examination points. Furthermore, both SGs had better TBUT times at all examination points compared to CG (CG: 8.86 ± 1.08, SG1: 9.59 ± 1.45, CG2: 9.45 ± 1.33, p  < 0.05). BD was significantly better in both SGs only at the 1 st week of examination, while SDI values were better until the 3 rd week and only borderline better at 6 th week. Lastly, no significant differences were detected between SGs, regarding all parameters, at all examination points. Polyethylene glycol 400/propylene glycol

Does major surgery induce immune suppression and increase the risk of postoperative infection?

Torrance, Hew D T; Pearse, Rupert M; O'Dwyer, Michael J

2016-06-01

Infection is the commonest cause of a postoperative complication. Following major surgery alterations in immune function are commonplace and these may contribute to an enhanced susceptibility to acquire nosocomial infections. This review will discuss postoperative infections in the context of an altered perioperative immune response and the factors influencing this response. Up to 10% of patients undergoing elective in-patient surgery may develop a postoperative infection. Laboratory advances now permit systematic monitoring of single-cell immune signatures, which enable a clearer description of the interaction between tissue damage, immune modulation and clinical outcomes. Traditional candidate gene expression has identified pathways that define the detrimental immune modulating effects of perioperative allogeneic blood transfusion. Large clinical studies have demonstrated that the choice of anaesthetic technique may have an impact on postoperative infections through differential immune modulation. Point of care tests are emerging that allow monitoring of the perioperative immune response. These could be further developed to introduce personalised care pathways. Consideration must also be given to anaesthesia techniques and perioperative treatments that may be associated with poor outcomes through immune modulation.

Postoperative intraspinal subdural collections in children after posterior fossa tumor resection may temporarily hinder metastasis detection by MR imaging or CSF analysis, potentially impacting therapy. We investigated the incidence, imaging and clinical features, predisposing factors, and time course of these collections after posterior fossa tumor resection. Retrospective review of postoperative spine MRI in 243 children (5.5 ± 4.6 years of age) from our clinical data base postresection of posterior fossa tumors from October 1994 to August 2010 yielded 37 (6.0 ± 4.8 years of age) subjects positive for postoperative intraspinal subdural collections. Their extent and signal properties were recorded for postoperative (37/37), preoperative (15/37), and follow-up spine (35/37) MRI. Risk factors were compared with age-matched internal controls (n = 37, 5.9 ± 4.5 years of age). Associations of histology, hydrocephalus and cerebellar tonsillar herniation, and postoperative intracranial subdural collections with postoperative intraspinal subdural collections were assessed by the Fisher exact test or χ(2) test. The association between preoperative tumor volume and postoperative intraspinal subdural collections was assessed by the Wilcoxon rank sum test. The overall incidence of postoperative intraspinal subdural collections was 37/243 (15.2%), greatest ≤7 days postoperatively (36%); 97% were seen 0-41 days postoperatively (12.9 ± 11.0 days). They were T2 hyperintense and isointense to CSF on T1WI, homogeneously enhanced, and resolved on follow-up MR imaging (35/35). None were symptomatic. They were associated with intracranial subdural collections (P = .0011) and preoperative tonsillar herniation (P = .0228). Postoperative intraspinal subdural collections are infrequent and clinically silent, resolve spontaneously, and have a distinctive appearance. Preoperative tonsillar herniation appears to be a predisposing factor. In this series, repeat MR imaging by 4 weeks

To investigate direct postoperative outcome and plasma amino acid concentrations in a study comparing early enteral nutrition versus early parenteral nutrition after major rectal surgery. Previously, it was shown that a low plasma glutamine concentration represents poor prognosis in ICU patients. A preplanned substudy of a previous prospective, randomized, open-label, single-centre study, comparing early enteral nutrition versus early parenteral nutrition in patients at high risk of postoperative ileus after surgery for locally advanced or locally recurrent rectal cancer. Early enteral nutrition reduced postoperative ileus, anastomotic leakage, and hospital stay. Tertiary referral centre for locally advanced and recurrent rectal cancer. A total of 123 patients with locally advanced or recurrent rectal carcinoma requiring major rectal surgery. Patients were randomized (ALEA web-based external randomization) preoperatively into two groups: early enteral nutrition (early enteral nutrition, intervention) by nasojejunal tube (n = 61) or early parenteral nutrition (early parenteral nutrition, control) by jugular vein catheter (n = 62). Eight hours after the surgical procedure artificial nutrition was started in hemodynamically stable patients, stimulating oral intake in both groups. Blood samples were collected to measure plasma glutamine, citrulline, and arginine concentrations using a validated ultra performance liquid chromatography-tandem mass spectrometric method. Baseline concentrations were comparable for both groups. Directly after rectal surgery, a decrease in plasma amino acids was observed. Plasma glutamine concentrations were higher in the parenteral group than in the enteral group on postoperative day 1 (p = 0.027) and day 5 (p = 0.008). Arginine concentrations were also significantly increased in the parenteral group at day 1 (p < 0.001) and day 5 (p = 0.001). Lower plasma glutamine and arginine concentrations were measured in the enteral group, whereas a

Eighty-four consecutive patients requiring surgical removal of a single mandibular impacted third molar under local anesthesia were randomly assigned to receiving no drug (control group, Group A), postoperative 40 mg bromelain every 6 hours for 6 days (Group B), preoperative 4 mg dexamethasone sodium phosphate as a submucosal injection (Group C), and preoperative 4 mg dexamethasone sodium phosphate as a submucosal injection plus postoperative 40 mg bromelain every 6 hours for 6 days (Group D). Standardized surgical and analgesic protocols were adopted. Maximum interincisal distance and facial contours were measured at baseline and on postoperative days 2 and 7. Pain was measured objectively by counting the number of analgesic tablets required. Patient perception of the severity of symptoms was assessed with a follow-up questionnaire (PoSSe scale). On postoperative day 2, there was a statistically significant reduction in facial edema in both Groups C and D compared with the control group, but no statistically significant differences were observed between Group B and the control group. At evaluation on postoperative day 7, Group D showed a statistically significant reduction in postoperative swelling compared with the control group. The combined use of bromelain and dexamethasone (Group D) induced a statistically significant reduction in the total number of analgesic tablets taken after surgery compared with the control group. The treatment groups had a limited, nonsignificant effect on trismus when compared with the control group. Bromelain used singly showed moderate anti-inflammatory efficacy, reducing postoperative swelling, albeit not to any significant extent compared with no drug administration. The combined use of bromelain and dexamethasone sodium phosphate yielded

Studies on the 'gut origin of sepsis' have suggested that stressful insults, such as surgery, can affect intestinal permeability, leading to bacterial translocation. Symbiotics have been reported to be able to improve gut permeability and modulate the immunologic system, thereby decreasing postoperative complications. Therefore we aimed to evaluate the postoperative use of symbiotics in head and neck cancer surgical patients for intestinal function and permeability, as well as the postoperative outcomes. Patients were double-blind randomised into the symbiotic (n 18) or the control group (n 18). Samples were administered twice a day by nasoenteric tube, starting on the 1st postoperative day until the 5th to 7th day, and comprised 109 colony-forming units/ml each of Lactobacillus paracasei, L. rhamnosus, L. acidophilus, and Bifidobacterium lactis plus 6 g of fructo-oligosaccharides, or a placebo (6 g of maltodextrin). Intestinal function (day of first evacuation, total stool episodes, stool consistency, gastrointestinal tract symptoms and gut permeability by diamine oxidase (DAO) enzyme) and postoperative complications (infectious and non-infectious) were assessed. Results of comparison of the pre- and postoperative periods showed that the groups were similar for all outcome variables. In all, twelve patients had complications in the symbiotic group v. nine in the control group (P>0·05), and the preoperative-postoperative DAO activity ranged from 28·5 (sd 15·4) to 32·7 (sd 11·0) ng/ml in the symbiotic group and 35·2 (sd 17·7) to 34·1 (sd 12·0) ng/ml in the control group (P>0·05). In conclusion, postoperative symbiotics did not impact on intestinal function and postoperative outcomes of head and neck surgical patients.

The health benefits of probiotics and synbiotics are well established in healthy adults, but their role in preventing postoperative sepsis remains controversial. This meta-analysis assesses the impact of probiotics and synbiotics on the incidence of postoperative sepsis in gastrointestinal (GI) surgical patients. A comprehensive literature search of all published randomized control trials (RCTs) was conducted using PubMed, Cochrane Central Registry of Controlled Trials, and Google Scholar (1966-2015). Inclusion criteria included RCTs comparing the use of any strain or dose of a specified probiotic/synbiotic with placebo or a "no treatment" control group. The incidence of postoperative sepsis (within 1 month of surgery) and postoperative mortality were analyzed. Fifteen RCTs involving 1201 patients (192 receiving probiotics, 413 receiving synbiotics, and 596 receiving placebo) were analyzed. Overall, probiotic and synbiotic uses significantly reduced the risk of developing postoperative sepsis by 38 % (relative risk (RR) = 0.62, 95 % confidence interval (CI) 0.52-0.74, p < 0.001). The use of probiotic/synbiotic supplementation is associated with a significant reduction in the risk of developing postoperative sepsis in patients undergoing elective GI surgery. Probiotic/synbiotic supplementation is a valuable adjunct in the care of patients undergoing GI surgery. Additional studies are required to determine the optimal dose and strain of probiotic/synbiotic.

The correlation between incidental parathyroidectomy (IP) during thyroidectomy and postoperative hypocalcemia remains controversial. Our aim was to investigate the incidence of IP, risk factors, and impact on patient outcomes. Retrospective cohort study. This was a retrospective observational study including 3,186 consecutive patients who underwent thyroidectomy between January 2007 and December 2014. The patients were divided into two groups: the IP group and the non-IP. Numerous clinical parameters were collected and analyzed. The overall incidence of incidentally excised parathyroid glands during thyroidectomy was 6.4%. Patients with IP had significantly higher incidences of postoperative hypocalcemia and hypoparathyroidism than those without IP (P < 0.001). Intrathyroidal parathyroid glands presented only 2.2% of all removed parathyroid glands. Total thyroidectomy, central compartment lymph node dissection, and reoperation were independent risk factors for IP. Incidental parathyroidectomy during thyroidectomy is associated with the increased likelihood of postoperative hypocalcemia. All independent risk factors examined in the study for IP are surgery-related. Surgeons should perform meticulous dissection with the intention of avoiding IP and resultant hypocalcemia. 4.

Gastrointestinal Stromal Tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract (GIT). Importance of GISTs is increasing while surgeons are facing with more frequent either in emergency setting of elective cases. Delineating the presentation and management of emergency GIST is important. From 2005 to 2014, emergency cases with final diagnosis of GIST were examined retrospectively. Total of 13 operated cases were evaluated by patients characteristics, clinical presentation, operational findings and postoperative prognosis. There were 9 male and 4 female with the mean age of 48.15 years. The most frequent presentations are ileus and GIT hemorrhage both covering the 84% of patients. Small bowel was the dominating site with ileus. Stomach was the second frequent site of the disease with the finding of hemorrhage. Emergency patients are more likely to come with small bowel GIST and obstruction symptoms. Hemorrhage is the most frequent symptom for emergency GIST of stomach and duodenum.

[Therapeutic approach to postoperative anemia].

Postoperative anemia is a common finding in patients who undergo major surgery, and it can affect early rehabilitation and the return to daily activities. Allogeneic blood transfusion is still the most widely used method for restoring hemoglobin levels rapidly and effectively. However, the potential risks of transfusions have led to the review of this practice and to a search for alternative measures for treating postoperative anemia. The early administration of intravenous iron appears to improve the evolution of postoperative hemoglobin levels and reduce allogeneic transfusions, especially in patients with significant iron deficiency or anemia. What is not clear is whether this treatment heavily influences rehabilitation and quality of life. There is a lack of well-designed, sufficiently large, randomized prospective studies to determine whether postoperative or perioperative intravenous iron treatment, with or without recombinant erythropoietin, has a role in the recovery from postoperative anemia, in reducing transfusions and morbidity rates and in improving exercise capacity and quality of life.

Coma is a state of profound unresponsiveness that can occur as a serious perioperative complication. The study of risk factors for, and sequelae of, postoperative coma has been limited due to the rarity of the event. To determine the incidence, risk factors and impact of postoperative coma in a large patient population. Observational study using a prospectively gathered national dataset. Data from 858 606 patients were analysed. The incidence of postoperative coma of more than 24-h duration was identified. Logistic regression was used to identify independent predictors and develop a risk model of postoperative coma in derivation and validation cohorts; 30-day mortality was also analysed. The incidence of postoperative coma was 0.06%. Multivariate analysis revealed the following independent predictors: liver disease, systemic sepsis, age at least 63 years, renal disease, emergency operation, cardiac disease, hypertension, prior neurological disease, diabetes mellitus and BMI 25 to 29.99 kg m (protective). These predictors were incorporated into a risk index classification; odds ratios for postoperative coma increased from 2.5 with one risk factor to 18.4 with three. Coma was associated with 74.2% all-cause mortality; coma associated with cardiac arrest had a 1.9-fold higher mortality. This is the largest study of postoperative coma ever reported and will be useful for determining risk of coma of more than 24 h duration when evaluating an unresponsive patient following surgery. Data on prognosis will aid medical and ethical decision-making for the comatose surgical patient.

The authors hypothesized that the use of incentive spirometry by orthopedic patients is less than the recommended level and is affected by patient-related factors and type of surgery. To determine its postoperative use, the authors prospectively surveyed all patients in their institution's general orthopedic ward who had undergone elective spine surgery or total knee or hip arthroplasty during a consecutive 3-month period in 2010, excluding patients with postoperative delirium or requiring a monitored bed. All 182 patients (74 men, 108 women; average age, 64.5 years; range, 32-88 years; spine group, n=55; arthroplasty group, n=127), per protocol, received preoperative spirometry education by a licensed respiratory therapist (recommended use, 10 times hourly) and reinforcement education by nurses. Patients were asked twice daily (morning and evening) regarding their spirometry use during the previous 1-hour period by a registered nurse on postoperative days 1 through 3. All data were collected by the same 2 nurses using the same standardized questionnaire. Spirometry use was correlated with surgery type, postoperative day/time, and patient's age and sex. Student's t test, Spearman test, and one-way analysis of variance were used to compare differences (P<.05). Spirometry use averaged 4.1 times per hour (range, 0-10 times). No statistical correlations were found between spirometry use and age. Sex did not influence spirometry use. The arthroplasty group reported significantly higher use than did the spine group: 4.3 and 3.5 times per hour, respectively. Mean use increased significantly between postoperative days 1, 2, and 3.

This study was designed to investigate the clinical impact of postoperative serum albumin level on severe postoperative complications (SPCs) and prognosis. Data for a total of 728 consecutive patients who underwent curative gastrectomy for gastric cancer between 2004 and 2013 were retrospectively analyzed. From these patients, a propensity score-matched analysis was performed based on 14 clinicopathological and surgical factors. Short-term decrease in postoperative serum albumin level was not associated with the occurrence of SPCs. Regarding long-term decrease in serum albumin level, a decrease of ≥0.5 g/dl at 3 months did not affect the long-term survival of patients without SPCs, but was related to a significantly poorer prognosis in patients with SPCs. By multivariate analysis, long-term decrease of serum albumin level was an independent prognostic factor in patients with SPCs. Long-term postoperative nutritional status as shown by a low level of albumin was related to prognosis in patients with SPCs.

Neonatal leukemia is a rare disease with an estimated prevalence of about one to five in a million neonates. The majority being acute myeloid leukemia (AML), neonatal leukemia can present with a variety of symptoms including hyperleucocytosis, cytopenia, hepatosplenomegaly, and skin infiltrates. Chromosomal rearrangements including mixed lineage leukemia (MLL) translocations are common in neonatal AML. A female neonate born at 34 weeks gestation presented with cardiorespiratory failure, hepatosplenomegaly, pancytopenia, and coagulopathy. She required intensive care treatment including mechanical ventilation, high-dose catecholamine therapy, and multiple transfusions. Small intestinal biopsy obtained during laparotomy for meconium ileus revealed an infiltrate by an undifferentiated monoblastic, MLL-rearranged leukemia. No other manifestations of leukemia could be detected. After spontaneous clinical remission, lasting 5 months without any specific treatment, the patient presented with leukemia cutis and full-blown monoblastic leukemia. MLL-AF10-rearranged AML could be re-diagnosed and successfully treated with chemotherapy and hematopoietic stem cell transplantation. Our patient exhibited a unique manifestation of neonatal MLL-AF10 rearranged AML with cardiorespiratory failure and intestinal infiltration. It highlights the importance of leukemia in the differential diagnosis of neonatal distress, congenital hematological abnormalities, and skin lesions.

Objectives: To evaluate the anti-inflammatory and analgesic effect of Bromelain (pineapple extract) administered orally in the postoperative after extraction of impacted lower molars. Study Design: This is a prospective, placebo-controlled, unicentric, double-blind study; the sample size was 34 patients. The pre and postoperative outcomes, evaluated on the third (D3) and eighth day (D8), included inflamtion, pain and oral aperture, as well as the need for analgesics. One group received bromelain 150mg per day for three days and 100mg on days 4 to 7. The other group received placebo in the same dosage. All outcomes werrecorded quantitatively and analyzed with the Mann-Whitney U test for independent samples. Results: Although there were no statistically significant differences between the treatment groups, a trend towards less inflammation and improved oral aperture was observed in the group that received bromelain, compared to the group that received placebo. This trend can be attributed completely to random reasons, since there is no statistical difference in the results. Conclusions: Further studies are necessary to analyze different administration patterns and doses of bromelain for the use in the postoperative of impacted third molars. Key words:Tooth extraction, third molar, postoperative period, bromeline, clinical study. PMID:24316697

Vitamin C has critical features relavant to postoperative pain management and functional improvement; however, no study has yet evaluated the effectiveness of vitamin C on improving the surgical outcomes for spine pathologies. Thus, this study aimed to explore the impact of vitamin C on postoperative outcomes after single-level posterior lumbar interbody fusion (PLIF) for lumbar spinal stenosis in prospectively randomized design. We conducted a 1-year prospective, randomized, placebo-controlled, double-blind study to evaluate the impact of vitamin C on the postoperative outcomes after PLIF surgery. A total of 123 eligible patients were randomly assigned to either group A (62 patients with vitamin C) or group B (61 patients with placebo). Patient follow-up was continued for at least 1 year after surgery. The primary outcome measure was pain intensity in the lower back using a visual analogue scale. The secondary outcome measures were: (1) the clinical outcome assessed using the Oswestry Disability Index (ODI); (2) the fusion rate assessed using dynamic radiographs and computed tomography scans; and (3) complications. Pain intensity in the lower back was significantly improved in both groups compared with preoperative pain intensity, but no significant difference was observed between the 2 groups over the follow-up period. The ODI score of group A at the third postoperative month was significantly higher than the score of group B. After the sixth postoperative month, the ODI score of group A was slightly higher than the score of group B; however, this difference was not significant. The fusion rates at 1 year after surgery and the complication rates were not significantly different between the 2 groups. Postoperative pain intensity, the primary outcome measure, was not significantly different at 1 year after surgery between the 2 groups. However, vitamin C may be associated with improving functional status after PLIF surgery, especially during the first 3

Impact of postoperative non-steroidal anti-inflammatory drugs on adverse events after gastrointestinal surgery.

Recent evidence has suggested an association between postoperative non-steroidal anti-inflammatory drugs (NSAIDs) and increased operation-specific complications. This study aimed to determine the safety profile following gastrointestinal surgery across a multicentre setting in the UK. This multicentre study was carried out during a 2-week interval in September-October 2013. Consecutive adults undergoing elective or emergency gastrointestinal resection were included. The study was powered to detect a 10 per cent increase in major complications (grade III-V according to the Dindo-Clavien classification). The effect of administration of NSAIDs on the day of surgery or the following 2  days was risk-adjusted using propensity score matching and multivariable logistic regression to produce adjusted odds ratios (ORs). The type of NSAID and the dose were registered. Across 109 centres, early postoperative NSAIDs were administered to 242 (16·1 per cent) of 1503 patients. Complications occurred in 981 patients (65·3 per cent), which were major in 257 (17·1 per cent) and minor (Dindo-Clavien grade I-II) in 724 (48·2 per cent). Propensity score matching created well balanced groups. Treatment with NSAIDs was associated with a reduction in overall complications (OR 0·72, 95 per cent confidence interval 0·52 to 0·99; P  = 0·041). This effect predominantly comprised a reduction in minor complications with high-dose NSAIDs (OR 0·57, 0·39 to 0·89; P = 0·009). Early use of NSAIDs is associated with a reduction in postoperative adverse events following major gastrointestinal surgery. © 2014 BJS Society Ltd. Published by John Wiley & Sons Ltd.

As adjuvant chemotherapy in colorectal cancer relies on the identification of lymph node metastases, the pathologist's dedication may have a considerable influence on postoperative survival. The aim of this retrospective study was to assess the impact of the pathologist's dedication on lymph node detection rate and postoperative survival in patients operated on by a single experienced colorectal surgeon within a 5-year period. We assessed 229 patients undergoing total mesorectal excision or complete mesocolic excision by the senior author between 1 January 2009 and 31 December 2013. Pathologists were grouped as 'general pathologist' or 'dedicated pathologist' depending on their dedication/specialization. Dedicated pathologists found statistically significantly more lymph nodes in colorectal specimens than general pathologists [23 (interquartile range 24) vs 14 (interquartile range 11), respectively; P < 0.001]. The detection rate of ≥ 12 lymph nodes per specimen was significantly higher in the dedicated pathologist group [65/74 (87.8%) vs 105/155 (67.7%); P = 0.016]. However, postoperative survival did not differ in the respective subgroups. In the multivariable analysis by Cox proportional hazard model, International Union against Cancer Stage IV was the only factor associated with decreased disease-specific survival (hazard ratio 28.257; 95% CI 3.850-207.386; P = 0.001). In our centre, the pathologist's dedication has an impact on lymph node detection rate but does not influence postoperative disease-specific survival.

Unrelieved postoperative pain may have a negative impact on the physiological and psychological well-being of patients. Pharmacological methods are currently used to relieve such pain in gynecological patients; however, inadequate pain control is still reported, and the use of nonpharmacological pain-relieving methods is increasingly being advocated, one of which is music therapy. The purpose of this literature review was to identify, summarize, and critically appraise current evidence on music therapy and postoperative pain management among gynecological patients. A systematic search of MEDLINE, CINAHL, PsycINFO, British Nursing Index, and Allied and Complementary Medicine was conducted using the search terms music, gynecological, pain, surgery, operative, and post-operative to identify relevant articles in English from 1995 to the present. All identified articles were assessed independently for inclusion into review. A total of 7 articles were included after removal of duplicates and exclusion of irrelevant studies. All the included studies assessed the effects of music therapy on postoperative pain intensity, and three of them measured pain-related physiological symptoms. The findings indicated that music therapy, in general, was effective in reducing pain intensity, fatigue, anxiety, and analgesic consumption in gynecological patients during the postoperative period. It is recommended as an adjunct to pharmacological pain-relieving methods in reducing postoperative pain. Future researches on music therapy to identify the most effective application and evaluate its effect by qualitative study are recommended.

Ultrasonography of the postoperative musculoskeletal system plays an important role in the accurate diagnosis of abnormal lesions in the bone and soft tissues. Ultrasonography is a fast and reliable method with no harmful irradiation for the evaluation of postoperative musculoskeletal complications. In particular, it is not affected by the excessive metal artifacts that appear on computed tomography or magnetic resonance imaging. Another benefit of ultrasonography is its capability to dynamically assess the pathologic movement in joints, muscles, or tendons. This article discusses the frequent applications of musculoskeletal ultrasonography in various postoperative situations including those involving the soft tissues around the metal hardware, arthroplasty, postoperative tendons, recurrent soft tissue tumors, bone unions, and amputation surgery.

We report the case of a 39-year-old woman with ileus resulting from a small bowel incarceration underneath the right common iliac artery. The patient had a history of a radical trachelectomy with laparoscopic pelvic lymphadenectomy ("Dargent's operation") for cervical carcinoma. After dissection of the iliac vessels, a small bowel loop could slide underneath the common iliac artery. The hernia was closed by gluing a collagen patch over the right common iliac artery onto the retroperitoneal cavity. To our knowledge, such a case has not previously been reported in the medical literature.

To investigate the impact of preoperative oral liquid carbohydrate on postoperative insulin resistance (IR) in gastric cancer patients undergoing elective resection, and to examine the association of IR index (homeostasis model assessment, HOMA-IR) with tumor necrosis factor-α (TNF-α). Between January 2013 and September 2013, 35 patients undergoing elective resection for gastric cancer were prospectively enrolled and randomized into two groups. Patients in trial group (n=18) received oral 500 ml of 10% glucose solution two hours before surgery. Patients in control group (n=17) were asked to fast for 8-12 hours before operation. About 300 mg of rectus abdominis and subcutaneous fatty tissues was removed before the closure of abdominal wall. Blood samples were collected to measure the serum concentration of TNF-α with double antibody sandwich ELISA in perioperative period (3-hour before operation, end of operation, 1-day and 3-day after operation). HOMA-IR was calculated on preoperative 3-hour and postoperative 1-day. Western blotting was used to detect protein expression of TNF-α. Correlation of HOMA-IR with TNF-α was examined. HOMA-IR on the first day after surgery was not different from that at 3-hour before surgery in trial group (P=0.090), which was significantly lower than that in control group (P=0.000). In trial group, serum TNF-α at the end of operation was higher than that at 3-hour before surgery, which declined rapidly on the first day after surgery and had no significant difference compared with that on the third day after surgery. In control group, serum TNF-α at the end of operation was also higher than that before surgery, which rose to the peak on the first day after surgery and was still higher than that at 3-hour before surgery. The TNF-α protein expression in muscle tissues of trial group was higher than that of control group (P=0.001), while no significant difference was observed between two groups in adipose tissues (P=0

Peripancreatic collections occur frequently after distal pancreatectomy. However, the sequelae of peripancreatic collections vary from case to case, and their clinical impact is uncertain. In this study, the correlations between CT findings of peripancreatic collections and complications after distal pancreatectomy were investigated. Ninety-six consecutive patients who had undergone distal pancreatectomy between 2010 and 2015 were retrospectively investigated. The extent and heterogeneity of peripancreatic collections and background clinicopathological characteristics were analyzed. The extent of peripancreatic collections was calculated based on three-dimensional computed tomography images, and the degree of heterogeneity of peripancreatic collections was assessed based on the standard deviation of their density on computed tomography. Of 85 patients who underwent postoperative computed tomography imaging, a peripancreatic collection was detected in 77 (91%). Patients with either a large extent or a high degree of heterogeneity of peripancreatic collection had a significantly higher rate of clinically relevant pancreatic fistula than those without (odds ratio 5.95, 95% confidence interval 2.12-19.72, p = 0.001; odds ratio 8.0, 95% confidence interval 2.87-24.19, p = 0.0001, respectively). A large and heterogeneous peripancreatic collection was significantly associated with postoperative complications, especially clinically relevant postoperative pancreatic fistula. A small and homogenous peripancreatic collection could be safely observed.

A 24-h-stay in the post-anesthesia care unit (PACU) is a common postoperative procedure after deep brain stimulation surgery (DBS). We evaluated the impact of a fast-track (FT) postoperative care protocol. An analysis was performed on all patients who underwent DBS in 2 periods: 2006, overnight monitored care (OMC group), and 2007-2013, FT care (FT group). The study included 19 patients in OMC and 95 patients in FT. Intraoperative complications occurred in 26.3% patients in OMC vs. 35.8% in FT. Post-operatively, one patient in OMC developed hemiparesis, and agitation in 2 patients. In FT, two patients with intraoperative hemiparesis were transferred to the ICU. While on the ward, 3 patients from the FT developed hemiparesis, two of them 48h after the procedure. Thirty eight percent of FT had an MRI scan, while the remaining 62% and all patients of OMC had a CT-scan performed on their transfer to the ward. One patient in OMC had a subthalamic hematoma. Two patients in FT had a pallidal hematoma, and 3 a bleeding along the electrode. A FT discharge protocol is a safe postoperative care after DBS. There are a small percentage of complications after DBS, which mainly occur within the first 6h. Copyright © 2016 Sociedad Española de Neurocirugía. Publicado por Elsevier España, S.L.U.

Laparoscopic approach in colorectal surgery has demonstrated to give advantages in terms of postoperative outcomes, particularly in high-risk patients. The aim was to assess the impact of patients' age on the short-term outcomes after laparoscopic right colectomy for cancer. From January 2004 to September 2014, all patients who underwent laparoscopic right colectomy for cancer in a single institution were divided into four groups (A: <64 years; B: 65-74 years; C: 75-84 years; D ≥85 years). Risk factors for postoperative complications were determined on multivariable analysis. Laparoscopic right colectomy was performed in 507 patients, including 171 (33.7%) in A, 168 (33.1%) in B, 131 (25.8) in C and 37 (7.4%) in D. Patients in Group C and Group D had higher ASA score (p<0.0001) and presented more frequently with anaemia (20.6% and 29.7%, p=0.001). Stages III and IV were more frequently encountered in groups C and D. Overall morbidity was 27.5% without any difference in the four groups (24.5%, 29.1%, 7.5% and 18.4% respectively, p=0.58). The rate of minor complications (such as wound infection or postoperative ileus) was higher in Group D compared to other groups (p=0.05). The only independent variable correlated with postoperative morbidity was intraoperative blood transfusion (OR 2.82; CI 95% 1.05-4.59, p<0.0001). The present series suggests that patient's age did not significantly jeopardize the postoperative outcomes after laparoscopic right colectomy for cancer.

To describe psychosocial concerns associated with the postoperative cancer patient and to discuss current psychosocial evidence-based approaches to manage these psychosocial concerns. Published peer-reviewed literature. The postoperative phase of cancer care may be associated with a range of overlapping acute and chronic psychosocial concerns related to the surgery itself, the cancer diagnosis, and the need for ongoing cancer treatments. The postoperative period of cancer care represents an essential time to detect unmet psychosocial concerns and begin timely interventions for these concerns. Nurses are in a key position to detect, triage, refer, or manage psychosocial concerns in the postoperative patient with cancer. Current psychosocial evidence-based approaches may be used by surgical oncology nurses or other nurses who care for cancer patients during postoperative recovery. Copyright © 2016.

Legionella pneumophila postoperative pneumonia may be an important cause of morbidity and mortality in selected surgical patients. This report presents five postoperative neurosurgical patients in whom the diagnosis of Legionnaires' disease was made. Their clinical course and treatment are presented. Clinical manifestations, methods of diagnosis, and treatment of L. pneumophila pneumonia are discussed. It is pointed out that neurosurgical patients who have received high doses of corticosteroids and who develop nosocomial postoperative pneumonias should be suspected of having Legionnaires' disease.

Postoperative cerebrovascular accidents in general surgery.

Larsen, S F; Zaric, D; Boysen, G

1988-11-01

In a prospective study of postoperative complications, strokes occurred in 6 out of 2463 patients (0.2%) who underwent non-cardiac, non-carotid artery surgery. The patients who experienced cerebrovascular accidents, including three cases of transient ischemic attack, were significantly older than the rest of the group (mean age 79 years versus 65 years) and had manifestations of atherosclerosis in at least one organ preoperatively. Significant predictors of risk for postoperative cerebrovascular accidents were previous cerebrovascular disease, heart disease, peripheral vascular disease, and hypertension. Cerebrovascular accidents occurred late in the postoperative period, 5-26 days after surgery, and were not directly related to surgery and anesthesia. They were more frequent after acute than after elective operations. Precipitating factors for some of the stroke incidents were rapid atrial fibrillation and postoperative dehydration.

This study used a theoretical model to determine whether an efficacy-enhancing teaching protocol was effective in improving immediate postoperative behaviors and selected short- and long-term health outcomes in women who underwent abdominal hysterectomies. The model used was the self-efficacy theory of Albert Bandura, PhD. One hundred eight patients in a 486-bed teaching hospital in the Midwest who underwent hysterectomies participated. The participation rate was 85%, and the attrition rate was 17% during the six-month study. The major finding was that participants in the efficacy-enhancing teaching group ambulated significantly longer than participants in the usual care group. This is an important finding because the most prevalent postoperative complications after hysterectomy are atelectasis, pneumonia, paralytic ileus, and deep vein thrombosis, and postoperative ambulation has been shown to decrease or prevent all of these complications. This finding could affect the overall health status of women undergoing hysterectomies.

Four patients among a total of 2814 patients with a postoperative pneumothorax. Laparoscopic surgery for gynecologic benign disease. The main outcome was the clinical frequency and characteristics of the patients with postoperative pneumothorax. We observed 4 (0.14%) cases of postoperative pneumothorax after laparoscopic surgery, all of whom were diagnosed with endometriomas and developed a right-sided pneumothorax. The incidence of postoperative pneumothorax in 1097 patients with endometriomas was 0.36%, which was significantly higher than those without endometriomas. The presence of endometrioma should be considered a risk factor for postoperative pneumothorax in gynecologic laparoscopic surgery. Copyright © 2015 AAGL. Published by Elsevier Inc.

INTRODUCTION Between 4% and 13% of patients with operable pancreatic malignancy are found unresectable at the time of surgery. Double bypass is a good option for fit patients but it is associated with high risk of postoperative complications. The aim of this study was to identify pre-operatively which patients undergoing double bypass are at high risk of complications and to assess their long-term outcome. METHODS Of the 576 patients undergoing pancreatic resections between 2006 and 2011, 50 patients who underwent a laparotomy for a planned pancreaticoduodenectomy had a double bypass procedure for inoperable disease. Demographic data, risk factors for postoperative complications and pre-operative anaesthetic assessment data including the Portsmouth Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity (P-POSSUM) and cardiopulmonary exercise testing (CPET) were collected. RESULTS Fifty patients (33 men and 17 women) were included in the study. The median patient age was 64 years (range: 39–79 years). The complication rate was 50% and the in-hospital mortality rate was 4%. The P-POSSUM physiology subscore and low anaerobic threshold at CPET were significantly associated with postoperative complications (p=0.005 and p=0.016 respectively) but they were unable to predict them. Overall long-term survival was significantly shorter in patients with postoperative complications (9 vs 18 months). Postoperative complications were independently associated with poorer long-term survival (p=0.003, odds ratio: 3.261). CONCLUSIONS P-POSSUM and CPET are associated with postoperative complications but the possibility of using them for risk prediction requires further research. However, postoperative complications following double bypass have a significant impact on long-term survival and this type of surgery should therefore only be performed in specialised centres.

Background Vitamin C has critical features relavant to postoperative pain management and functional improvement; however, no study has yet evaluated the effectiveness of vitamin C on improving the surgical outcomes for spine pathologies. Thus, this study aimed to explore the impact of vitamin C on postoperative outcomes after single-level posterior lumbar interbody fusion (PLIF) for lumbar spinal stenosis in prospectively randomized design. We conducted a 1-year prospective, randomized, placebo-controlled, double-blind study to evaluate the impact of vitamin C on the postoperative outcomes after PLIF surgery. Methods A total of 123 eligible patients were randomly assigned to either group A (62 patients with vitamin C) or group B (61 patients with placebo). Patient follow-up was continued for at least 1 year after surgery. The primary outcome measure was pain intensity in the lower back using a visual analogue scale. The secondary outcome measures were: (1) the clinical outcome assessed using the Oswestry Disability Index (ODI); (2) the fusion rate assessed using dynamic radiographs and computed tomography scans; and (3) complications. Results Pain intensity in the lower back was significantly improved in both groups compared with preoperative pain intensity, but no significant difference was observed between the 2 groups over the follow-up period. The ODI score of group A at the third postoperative month was significantly higher than the score of group B. After the sixth postoperative month, the ODI score of group A was slightly higher than the score of group B; however, this difference was not significant. The fusion rates at 1 year after surgery and the complication rates were not significantly different between the 2 groups. Conclusions Postoperative pain intensity, the primary outcome measure, was not significantly different at 1 year after surgery between the 2 groups. However, vitamin C may be associated with improving functional status after PLIF surgery

Postoperative hand therapy in patients after surgery for Dupuytren's contracture is common medical practice to improve outcomes. Until now, patients are referred for postoperative hand rehabilitation on an empirical basis. To evaluate whether referral criteria after surgery because of Dupuytren's disease were actually adhered to, and, to analyse differences in outcomes between patients who were referred according to the criteria (correctly referred) and those who were not referred but should have been (incorrectly not referred). Referral pattern was evaluated prospectively in 46 patients. Total active/passive range of joint motion (TAM/ TPM), sensibility, pinch force, Disability Arm Shoulder Hand questionnaire (DASH) and Michigan Hand outcomes Questionnaire (MHQ) were used as outcome measures preoperatively and 10 months postoperatively. In total 21 patients were referred correctly and 17 patients were incorrectly not referred. Significant improvements on TAM/TPM, DASH and MHQ were found at follow-up for the total group. No differences in outcomes were found between patients correctly referred and patients incorrectly not referred for postoperative hand therapy. Referral criteria were not adhered to. Given the lack of differences in outcomes between patients correctly referred and patients incorrectly not referred, postoperative hand therapy in Dupuytren's disease should be reconsidered.

The efficacy of postoperative incentive spirometry is influenced by the device-specific imposed work of breathing.

The study evaluated the impact of the additional imposed work of breathing (WBimp) generated by two different spirometers on postoperative incentive spirometry performance in patients at high risk and moderate risk for postoperative pulmonary complications (PPCs). Additionally, we investigated whether maximal inspiratory pressure (PImax) is an easy estimate of the WBimp imposed by incentive spirometers. Prospective, randomized, single-blind clinical trial. ICU of a university hospital. Thirty male patients were assigned to a group at high risk for PPCs (group A; inspiratory capacity [IC], < 1.6 L) or to a group at moderate risk for PPCs (group B; IC, 1.6 to 2.5 L) after upper-abdominal, thoracic, or two-cavity surgery. On the first or second postoperative day WBimp, IC, and PImax were recorded without spirometers (baseline) and during incentive spirometry with the Mediflo spirometer (Medimex; Hamburg, Germany) (high WBimp) and the Coach spirometer (Kendall; Neustadt, Germany) (low WBimp) using a pneumotachograph. In group A, the baseline and the ICs for both spirometers only differed slightly. In group B, the IC was significantly reduced for the Mediflo (p < 0.05), which imposed a WBimp twice as high as the Coach (p < 0.01). PImax was significantly increased for both the Mediflo and the Coach (p < 0.01). PImax was positively correlated with WBimp (r = 0.8). Incentive spirometers differ considerably in their additional Wbimp with a potential impact on the efficacy of postoperative incentive spirometry performance. PImax might be an easy clinical estimate for the WBimp during incentive spirometry. Incentive spirometers with low WBimp permit increased maximal sustained inspiration and, thus, enhanced incentive spirometry performance, and, therefore, it might be more suitable for use in postoperative respiratory care.

Effects of preoperative one week enteral nutrition (EN) support on the postoperative nutritional status, immune function and inflammatory response of gastric cancer patients were investigated. 106 cases of gastric cancer patients were randomly divided into preoperative one week EN group (trial group) and early postoperative EN group (control group), which were continuously treated with EN support until the postoperative 9th day according to different treatment protocols. All the patients were checked for their body weight, skinfold thickness, upper arm circumference, white blood cell count (WBC), albumin (ALB), prealbumin (PA), C-reactive protein (CRP), humoral immunity (IgA, IgG), T cell subsets (CD4, CD8 and CD4/CD8), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), etc. on the preoperative and the postoperative 1st and 10th day, respectively. PA and IgG levels of the experimental group were higher than those of the control group on the postoperative 10th day, whereas IL-6 level of the experimental group was lower than that of the control group. EN support for preoperative gastric cancer patients will improve the postoperative nutritional status and immune function, alleviate inflammatory response, and facilitate the recovery of patients.

Evidence-based perianesthesia care: accelerated postoperative recovery programs.

Pasero, Chris; Belden, Jan

2006-06-01

Prolonged stress response after surgery can cause numerous adverse effects, including gastrointestinal dysfunction, muscle wasting, impaired cognition, and cardiopulmonary, infectious, and thromboembolic complications. These events can delay hospital discharge, extend convalescence, and negatively impact long-term prognosis. Recent advances in perioperative management practices have allowed better control of the stress response and improved outcomes for patients undergoing surgery. At the center of the current focus on improved outcomes are evidence-based fast-track surgical techniques and what is commonly referred to as "accelerated postoperative recovery programs." These programs require a multidisciplinary, coordinated effort, and nurses are essential to their successful implementation.

Our goal was to determine the optimal timing for repair of bile duct injuries sustained during cholecystectomy. Bile duct injury during cholecystectomy is a serious complication that often requires surgical repair. There is heterogeneity in the literature regarding the optimal timing of surgical repair, and it remains unclear to what extent timing determines postoperative morbidity and long-term anastomotic function. A single institution prospective database was queried for all E1 to E4 injuries from 1989 to 2014 using a standardized tabular reporting format. Timing was stratified into 3 groups [early (<7 days), intermediate (8 days until 6 weeks), and late (>6 weeks) after injury]. Analysis was stratified between those who had a previous bile duct repair or not, including postoperative complications and anastomotic failure as outcome variables in 2 separate multivariate logistic regression models. There were 614 patients included in the study. The mean age was 41 years (range, 15-85 yrs), and the majority were female (80%). The mean follow-up time was 40.5 months. Side-to-side hepaticojejunostomy was performed in 94% of repairs. Intermediate repair was associated with a higher risk of postoperative complications [odd ratio = 3.7, 95% confidence interval (1.3-10.2), P = 0.01] when compared with early and late in those with a previous repair attempt. Sepsis control and avoidance of biliary stents were protective factors against anastomotic failure. Adequate sepsis control and delayed repair of biliary injuries should be considered for patients presenting between 8 days and 6 weeks after injury to prevent complications, if a previous bile duct repair was attempted.

Postoperative refraction in the second eye having cataract surgery.

Leffler, Christopher T; Wilkes, Martin; Reeves, Juliana; Mahmood, Muneera A

2011-01-01

Introduction. Previous cataract surgery studies assumed that first-eye predicted and observed postoperative refractions are equally important for predicting second-eye postoperative refraction. Methods. In a retrospective analysis of 173 patients having bilateral sequential phacoemulsification, multivariable linear regression was used to predict the second-eye postoperative refraction based on refractions predicted by the SRK-T formula for both eyes, the first-eye postoperative refraction, and the difference in IOL selected between eyes. Results. The first-eye observed postoperative refraction was an independent predictor of the second eye postoperative refraction (P < 0.001) and was weighted more heavily than the first-eye predicted refraction. Compared with the SRK-T formula, this model reduced the root-mean-squared (RMS) error of the predicted refraction by 11.3%. Conclusions. The first-eye postoperative refraction is an independent predictor of the second-eye postoperative refraction. The first-eye predicted refraction is less important. These findings may be due to interocular symmetry.

Meconium ileus (MI) is a perinatal complication in cystic fibrosis (CF), which is only minimally influenced by environmental factors. We derived and examined MI prevalence (MIP) scores to assess CFTR phenotype-phenotype correlation for severe mutations. MIP scores were established using a Canadian CF population (n = 2,492) as estimates of the proportion of patients with MI among all patients carrying the same CFTR mutation, focusing on patients with p.F508del as the second allele. Comparisons were made to the registries from the US CF Foundation (n = 43,432), Italy (Veneto/Trentino/Alto Adige regions) (n = 1,788), and Germany (n = 3,596). The prevalence of MI varied among the different registries (13-21%). MI was predominantly prevalent in patients with pancreatic insufficiency carrying "severe" CFTR mutations. In this severe spectrum MIP scores further distinguished between mutation types, for example, G542X (0.31) with a high, F508del (0.22) with a moderate, and G551D (0.08) with a low MIP score. Higher MIP scores were associated with more severe clinical phenotypes, such as a lower forced expiratory volume in 1 second (P = 0.01) and body mass index z score (P = 0.04). MIP scores can be used to rank CFTR mutations according to their clinical severity and provide a means to expand delineation of CF phenotypes.Genet Med 18 4, 333-340.

Infliximab was approved for use in ulcerative colitis in recent years. It has been debated if infliximab increases the risk of post-operative complications in patients with ulcerative colitis. To perform a meta-analysis that examines the relationship between preoperative infliximab treatment and short-term post-operative complications in patients with ulcerative colitis. We searched the PubMed and MEDLINE databases to identify observational studies on the impact of pre-operative infliximab use on short-term post-operative complications in ulcerative colitis. Infectious complications mainly included wound infection, sepsis and abscess, whereas non-infectious complications included intestinal obstruction, thromboembolism and gastrointestinal haemorrhage. Pooled odds ratios (ORs) were calculated for each relationship. A total of 5 studies and 706 patients were included in our meta-analysis. Overall, we did not find a strong association between pre-operative treatment of infliximab and short-term infectious [OR 2.24, 95% confidence interval (CI) 0.63-7.95] or non-infectious (OR 0.85, 95% CI 0.50-1.45) post-operative complications in ulcerative colitis patients. On the contrary, we discovered that pre-operative infliximab use increased short-term total post-operative complications (OR 1.80, 95% CI 1.12-2.87). Pre-operative infliximab use increased the risk of short-term post-operative complications. Subgroup analysis is underpowered to assess the nature of these complications but shows a trend towards increased post-operative infection.

To investigate the impact of different cochleostomy techniques on vestibular receptor integrity and vertigo after cochlear implantation. Retrospective cohort study. A total of 62 patients (17 to 84 years of age) underwent implantation via an anterior or round window insertion approach. Two groups of cochlear implant patients were compared with respect to their pre- and postoperative vestibular function and the occurrence of postoperative vertigo. The data were related to the different cochleostomy techniques. The patients were tested by a questionnaire (dizziness handicap inventory, DIH), caloric irrigation (vestibulo-ocular reflex, VOR) for the function of the lateral SCC and by vestibular evoked myogenic potential (VEMP) recordings for saccular function. Significant differences of postoperative VEMP responses (50% vs 13%) and electromystagmography (ENG) results (42.9% vs 9.4%) were found with respect to the 2 different insertion techniques. The number of patients with vertigo after the surgery as evidenced by DHI (23% vs 12.5%) was significantly different. The used round window approach for electrode insertion should be preferred to decrease the risk of loss of vestibular function and the occurrence of vertigo.

To evaluate the anti-inflammatory and analgesic effect of Bromelain (pineapple extract) administered orally in the postoperative after extraction of impacted lower molars. This is a prospective, placebo-controlled, unicentric, double-blind study; the sample size was 34 patients. The pre and postoperative outcomes, evaluated on the third (D3) and eighth day (D8), included inflamtion, pain and oral aperture, as well as the need for analgesics. One group received Bromelain 150mg per day for three days and 100mg on days 4 to 7. The other group received placebo in the same dosage. All outcomes werrecorded quantitatively and analyzed with the Mann-Whitney U test for independent samples. Although there were no statistically significant differences between the treatment groups, a trend towards less inflammation and improved oral aperture was observed in the group that received Bromelain, compared to the group that received placebo. This trend can be attributed completely to random reasons, since there is no statistical difference in the results. Further studies are necessary to analyze different administration patterns and doses of Bromelain for the use in the postoperative of impacted third molars.

Postoperative effect of music listening has not been established in pediatric age. Response on postoperative distress and pain in pediatric day care surgery has been evaluated. Forty-two children were enrolled. Patients were randomly assigned to the music-group (music intervention during awakening period) or the non-music group (standard postoperative care). Slow and fast classical music and pauses were recorded and played via ambient speakers. Heart rate, blood pressure, oxygen saturation, glucose and cortisol levels, faces pain scale and Face, Legs, Activity, Cry, Consolability (FLACC) Pain Scale were considered as indicators of response to stress and pain experience. Music during awakening induced lower increase of systolic and diastolic blood pressure levels. The non-music group showed progressive increasing values of glycemia; in music-group the curve of glycemia presented a plateau pattern (P<0.001). Positive impact on reactions to pain was noted using the FLACC scale. Music improves cardiovascular parameters, stress-induced hyperglycemia. Amelioration on pain perception is more evident in older children. Positive effects seems to be achieved by the alternation of fast, slow rhythms and pauses even in pediatric age.

We studied the effects of enteral nutrition (EN) support initiated 1 week before surgery on postoperative nutritional status, immune function, and inflammatory response in gastric cancer patients. A total of 200 gastric cancer patients were randomly divided into two groups: EN starting 1 week before surgery (study group) and EN starting early after surgery (control group). The two groups received EN support, following different therapeutic schedules, until the 9th day after operation. In the patients, body weight, skinfold thickness, upper-arm circumference, white blood cell count, albumin, prealbumin, C-reactive protein, peripheral immunoglobulins (IgA, IgG, and IgM), T lymphocyte subsets, interleukin-6, and tumor necrosis factor-α were measured 10 days before and after surgery and on the first day after surgery. There was no statistically significant difference in the results of recovery time of passage of gas by anus, abdominal distension, stomachache, blood glucose, hepatic and renal functions, and electrolytes between the two groups of patients (P > 0. 05). Adverse reactions occurred to both groups at 1 and 2 days after operation. Such conditions was improved after the intravenous drip rate was adjusted. The albumin and prealbumin levels of the patients in both groups decreased at 1 day after operation (P < 0. 05). The levels rose when the research was finished (P < 0. 05). The prealbumin level of the study group was higher than that of the control group at 10 days after operation (P < 0. 05). The IgG level of the study group was higher than that of the control group at 10 days after operation (P < 0. 05). The two groups of inflammatory reaction indicators of the study group were lower than those of the control group at 10 days after operation (P < 0. 05). This study indicates that appropriate preoperative EN support for gastric cancer patients can improve their postoperative nutritional status and immune function, can reduce inflammatory response, and is

Brain natriuretic peptide (BNP) is a cardiac neurohormone known to correlate with left ventricular (LV) dilation, decreased contractility, and increased stiffness. Consequently, BNP has been used as a prognostic tool to assess the degree of LV unloading for patients supported by continuous-flow LV assist devices (LVADs). We assessed the prognostic value of changes in BNP in the 2 weeks after LVAD implantation. This retrospective study analyzed laboratory findings and outcomes of 189 LVAD patients. Patients were separated into two groups based on whether serum BNP levels had improved from preoperative levels by postoperative day 14. Group 1 had improvement in BNP levels, whereas group 2 had no improvement or worsening in BNP. There were no significant differences between the groups in age, gender, race, body mass index, or comorbidities. Group 1 had preoperative BNP 1,125 ± 1,078.3 pg/dl and postoperative BNP 440.2 ± 267.7 pg/dl (ΔBNP = -693.09 ± 942.4 pg/dl), whereas group 2 had preoperative BNP 346.0 ± 309.1 pg/dl and postoperative BNP 631.57 ± 483.4 pg/dl (ΔBNP = 289.32 ± 329.7 pg/dl). Postoperative survival in group 2 was significantly worse than in group 1. Rates of right ventricular failure (RVF) were significantly higher in group 2 (group 1: 39%, group 2: 52.7%; p = 0.01). In most patients implanted with a LVAD, BNP improves significantly in the postoperative period as the LV is unloaded. Our results indicate that lack of improvement in postoperative BNP is associated with longer length of stay, increased rates of RVF, and is an independent risk factor for reduced postoperative survival.

To analyze the safety of a standardized pediatric tracheostomy care protocol in the immediate postoperative period and its impact on tracheostomy related complications. Retrospective case series. Pediatric patients undergoing tracheotomy from February 2010-February 2014. In 2012, a standardized protocol was established regarding postoperative pediatric tracheostomy care. This protocol included securing newly placed tracheostomy tubes using a foam strap with hook and loop fastener rather than twill ties, placing a fresh drain sponge around the tracheostomy tube daily, and performing the first tracheostomy tube change on postoperative day 3 or 4. Outcome measures included rate of skin breakdown and presence of a mature stoma allowing for a safe first tracheostomy tube change. Two types of tracheotomy were performed based on patient age: standard pediatric tracheotomy and adult-style tracheotomy with a Bjork flap. Patients were analyzed separately based on age and the type of tracheotomy performed. Thirty-seven patients in the pre-protocol group and 35 in the post-protocol group were analyzed. The rate of skin breakdown was significantly lower in the post-protocol group (standard: p=0.0048; Bjork flap: p=0.0003). In the post-protocol group, all tube changes were safely accomplished on postoperative day three or four, and the stomas were deemed to be adequately matured to do so in all cases. A standardized postoperative pediatric tracheostomy care protocol resulted in decreased rates of skin breakdown and demonstrated that pediatric tracheostomy tubes can be safely changed as early as 3 days postoperatively.

To describe the preoperative and postoperative experience of children who have undergone heart-lung transplantation for cystic fibrosis. Retrospective descriptive study. Paediatric Surgical Unit, Harefield Hospital, Middlesex, Great Britain. Twelve children less than 15 years of age (mean age 11 years 10 months; range 7 to 14 years), six boys and six girls, who received heart-lung transplants between September 1987 and March 1991. All 12 children were alive and well 1 year after surgery, although one girl had undergone retransplantation in the eighth postoperative month. Actuarial survival rate was 66% at 2 years. Early results suggest that heart-lung transplantation is a successful therapeutic option for children with cystic fibrosis. Cystic fibrosis-related postoperative complications were malabsorption of immunosuppressive drugs, meconium ileus equivalent, and persisting infection in the upper respiratory tract. These and general complications of acute rejection and infection did not prevent 66% of the group from returning to their normal schooling within the first postoperative year. Obliterative bronchiolitis remains the most serious late complication after lung transplantation, and further research is needed into treatment and prevention.

Objective: To investigate the effect of postoperative precision nutrition therapy on postoperative recovery (PR) of patients with advanced gastric cancer (AGC) after neoadjuvant chemotherapy (NC). Methods: 71 subjects were randomly divided into 2 groups. The 34 patients of research group were treated with postoperative precision nutrition treatment according to the indirect energy measurement method. The 31 patients of control group were treated with traditional postoperative nutrition treatment. All participants were measured for body mass index (BMI), NRS2002, PG-SGA and relevant laboratory test within the 1st day before surgery and 7th day after surgery. Moreover, the difference between two groups in short-term effects were evaluated. Results: The daily energy supply of control group was 30.1%-43.74% higher than that of the experimental group ( P <0.05). The resting energy expenditure (REE) of the research group after surgery was lower than that before operation. The levels of prealbumin, albumin and lymphocyte count were higher in research group than the controls at the 7th day after surgery whereas the opposite was true for the creatinine, urea nitrogen, C-reactive protein and procalcitonin ( P <0.05). Similarly, the rate of malnutrition and nutritional risk became lower in the research group ( P <0.05). The gastrointestinal function recovery of patients in the research group was comparable to that of the control group ( P >0.05). Moreover, the complication rate and hospitalization costs of in research group were significantly lower than that of in control group ( P <0.05). For patients with or without nutritional risks before surgery, the nutritional index and inflammatory index in the research group were better than those in the control group. Conclusion: Postoperative precision nutrition therapy may improve the postoperative nutritional status and short-term effects of patients with AGC after NC.

The fibrosis score 4 (FIB-4) score is a useful tool to determine the degree of hepatic fibrosis. Liver fibrosis and cirrhosis are well-known predictors of postoperative complications after hepatectomy. This study examined the impact of FIB-4 on postoperative short-term outcomes of patients with hepatocellular carcinoma (HCC). Three hundred and fifty patients undergoing hepatectomy for HCC between 2008 and 2013 were enrolled. The receiver operating characteristic (ROC) curve analysis was performed to determine the cutoff value of the FIB-4. Univariate and multivariate analysis was performed to identify the risk factors. The correlation of the preoperative FIB-4 value with clinicopathological parameters was examined. Postoperative complications were observed in 202 (57.7%) patients. The optimal cutoff value of the FIB-4 was set at 2.88 and 3.85 for postoperative complications and intraoperative blood loss respectively. It was also an independent prognostic factor for postoperative complications (hazard ratio [HR], 1.202; 95% CI, 1.076-1.344; P = 0.001) and intraoperative blood loss (HR, 1.196; 95% CI, 1.091-1.343; P < 0.001) by multivariate analysis. The FIB-4 was significantly correlated with age, liver function, coagulation function, blood loss, intraoperative blood transfusion (all P < 0.05). Preoperative FIB-4 is a useful index to predict postoperative outcomes in patients with HCC. The FIB-4 should be assessed routinely for hepatocellular carcinoma patients.

Incidental gastrointestinal findings are commonly detected on MDCT exams performed for various medical indications. This review describes the radiological MDCT spectrum of appearances already present in the past literature and in today's experience of several gastrointestinal acute conditions such as abdominal hernia, giant colon diverticulum, GIST, intestinal pneumatosis, colon ischemia, cold intussusception, gallstone ileus, and foreign bodies which can require medical and surgical intervention or clinical follow-up. The clinical presentation of this illness is frequently nonspecific: abdominal pain, distension, nausea, fever, rectal bleeding, vomiting, constipation, or a palpable mass, depending on the disease. A proper differential diagnosis is essential in the assessment of treatment and in this case MDCT exam plays a central rule. We wish that this article will familiarize the radiologist in the diagnosis of this kind of incidental MDCT findings for better orientation of the therapy. PMID:28638830

The impact of intraoperative neuromonitoring on recurrent laryngeal nerve palsy remains debated. Our aim was to evaluate the potential protective effect of intraoperative neuromonitoring on recurrent laryngeal nerve during total thyroidectomy. This was a prospective, multicenter French national study. The use of intraoperative neuromonitoring was left at the surgeons' choice. Postoperative laryngoscopy was performed systematically at day 1 to 2 after operation and at 6 months in case of postoperative recurrent laryngeal nerve palsy. Univariate and multivariate analyses and propensity score (sensitivity analysis) were performed to compare recurrent laryngeal nerve palsy rates between patients operated with or without intraoperative neuromonitoring. Among 1,328 patients included (females 79.9%, median age 51.2 years, median body mass index 25.6 kg/m 2 ), 807 (60.8%) underwent intraoperative neuromonitoring. Postoperative abnormal vocal cord mobility was diagnosed in 131 patients (9.92%), including 69 (8.6%) and 62 (12.1%) in the intraoperative neuromonitoring and nonintraoperative neuromonitoring groups, respectively. Intraoperative neuromonitoring was associated with a lesser rate of recurrent laryngeal nerve palsy in univariate analysis (odds ratio = 0.68, 95% confidence interval, 0.47; 0.98, P = .04) but not in multivariate analysis (oddsratio = 0.74, 95% confidence interval, 0.47; 1.17, P = .19), or when using a propensity score (odds ratio = 0.76, 95% confidence interval, 0.53; 1.07, P = .11). There was no difference in the rates of definitive recurrent laryngeal nerve palsy (0.8% and 1.3% in intraoperative neuromonitoring and non-intraoperative neuromonitoring groups respectively, P = .39). The sensitivity, specificity, and positive and negative predictive values of intraoperative neuromonitoring for detecting abnormal postoperative vocal cord mobility were 29%, 98%, 61%, and 94%, respectively.

Postoperative pulmonary edema is a well-known postoperative complication caused as a result of numerous etiological factors which can be easily detected by a careful surveillance during postoperative period. However, there are no preoperative and intraoperative criteria which can successfully establish the possibilities for development of postoperative pulmonary edema. The aims were to review the possible etiologic and diagnostic challenges in timely detection of postoperative pulmonary edema and to discuss the various management strategies for prevention of this postoperative complication so as to decrease morbidity and mortality. The various search engines for preparation of this manuscript were used which included Entrez (including Pubmed and Pubmed Central), NIH.gov, Medknow.com, Medscape.com, WebMD.com, Scopus, Science Direct, MedHelp.org, yahoo.com and google.com. Manual search was carried out and various text books and journals of anesthesia and critical care medicine were also searched. From the information gathered, it was observed that postoperative cardiogenic pulmonary edema in patients with serious cardiovascular diseases is most common followed by noncardiogenic pulmonary edema which can be due to fluid overload in the postoperative period or it can be negative pressure pulmonary edema (NPPE). NPPE is an important clinical entity in immediate post-extubation period and occurs due to acute upper airway obstruction and creation of acute negative intrathoracic pressure. NPPE carries a good prognosis if promptly diagnosed and appropriately treated with or without mechanical ventilation. PMID:23439791

Postoperative cerebrospinal fluid (CSF) leak is a serious complication following trans-sphenoidal surgery for which elevated body mass index (BMI) has been implicated as a risk factor, albeit only in two recent North American studies. Given the paucity of evidence, we sought to determine if this association held true in an Asian population, where BMI criteria for obesity differ from the international standard. A retrospective study of 119 patients who underwent 123 trans-sphenoidal procedures for sellar lesions between May 2000 and May 2012 was conducted. Univariate and multivariate logistic regression analyses were performed to investigate the impact of elevated BMI and other risk factors on postoperative CSF leak. We found 10 (8.1%) procedures in ten patients that were complicated by postoperative CSF leak. The median BMI of patients with postoperative leak following trans-sphenoidal procedures was significantly higher than that of patients without postoperative CSF leak (27.0 kg/m2 vs. 24.6 kg/m2; p = 0.018). Patients categorised as either moderate or high risk under the Asian BMI classification were more likely to suffer from a postoperative leak (p = 0.030). Repeat procedures were also found to be significantly associated with postoperative CSF leak (p = 0.041). Elevated BMI predicts for postoperative CSF leak following trans-sphenoidal procedures, even in an Asian population, where the definition of obesity differs from international standards. Thus, BMI should be borne in mind during local and regional management decision-making processes prior to such procedures.

Postoperative atrial fibrillation or flutter (AF) is one of the most common complications of cardiac surgery and significantly increases morbidity and health care utilization. A few small trials have evaluated whether long-chain n-3-polyunsaturated fatty acids (PUFAs) reduce postoperative AF, with mixed results. To determine whether perioperative n-3-PUFA supplementation reduces postoperative AF. The Omega-3 Fatty Acids for Prevention of Post-operative Atrial Fibrillation (OPERA) double-blind, placebo-controlled, randomized clinical trial. A total of 1516 patients scheduled for cardiac surgery in 28 centers in the United States, Italy, and Argentina were enrolled between August 2010 and June 2012. Inclusion criteria were broad; the main exclusions were regular use of fish oil or absence of sinus rhythm at enrollment. Patients were randomized to receive fish oil (1-g capsules containing ≥840 mg n-3-PUFAs as ethyl esters) or placebo, with preoperative loading of 10 g over 3 to 5 days (or 8 g over 2 days) followed postoperatively by 2 g/d until hospital discharge or postoperative day 10, whichever came first. Occurrence of postoperative AF lasting longer than 30 seconds. Secondary end points were postoperative AF lasting longer than 1 hour, resulting in symptoms, or treated with cardioversion; postoperative AF excluding atrial flutter; time to first postoperative AF; number of AF episodes per patient; hospital utilization; and major adverse cardiovascular events, 30-day mortality, bleeding, and other adverse events. At enrollment, mean age was 64 (SD, 13) years; 72.2% of patients were men, and 51.8% had planned valvular surgery. The primary end point occurred in 233 (30.7%) patients assigned to placebo and 227 (30.0%) assigned to n-3-PUFAs (odds ratio, 0.96 [95% CI, 0.77-1.20]; P = .74). None of the secondary end points were significantly different between the placebo and fish oil groups, including postoperative AF that was sustained, symptomatic, or treated (231

Cardiac transplantation can be complicated by refractory hemorrhage particularly in cases where explantation of a ventricular assist device is necessary. Recombinant activated factor VII (rFVIIa) has been used to treat refractory bleeding in cardiac surgery patients, but little information is available on its efficacy or cost in heart transplant patients. Patients who had orthotopic heart transplantation between January 2009 and December 2014 at a single center were reviewed. Postoperative bleeding and the total costs of hemostatic therapies were compared between patients who received rFVIIa and those who did not. Propensity scores were created and used to control for the likelihood of receiving rFVIIa in order to reduce bias in our risk estimates. Seventy-six patients underwent heart transplantation during the study period. Twenty-one patients (27.6%) received rFVIIa for refractory intraoperative bleeding. There was no difference in postoperative red blood cell transfusion, chest tube output, or surgical re-exploration between patients who received rFVIIa and those who did not, even after adjusting with the propensity score (P = 0.94, P = 0.60, and P = 0.10, respectively). The total cost for hemostatic therapies was significantly higher in the rFVIIa group (median $10,819 vs. $1,985; P < 0.0001). Subgroup analysis of patients who underwent redo-sternotomy with left ventricular assist device explantation did not show any benefit for rFVIIa either. In this relatively small cohort, rFVIIa use was not associated with decreased postoperative bleeding in patients undergoing heart transplantation; however, it led to significantly higher cost.

Postoperative ileus (POI) is one of the most common complications of gastrointestinal surgery. The present study was performed to evaluate the effects of glutamine administration on POI after gastric surgery in humans. The subjects were 31 patients who underwent partial distal gastrectomy for gastric cancer and who were randomly assigned to one of two groups based on postoperative treatment: the glutamine group (3 g/day) and the control group. Manometric recording was done 12 days after surgery, and plasma glutamine concentrations were measured preoperatively and on postoperative day 12. Motor activities of the duodenum in the glutamine group were significantly greater than those of the control group in the interdigestive state. The incidence of phase III motor activity (interdigestive migrating motor contractions) in the glutamine group was significantly higher than that in the control group (60 versus 19%). The glutamine group showed a significantly smaller decrease of plasma glutamine levels compared with the control group. Glutamine could act as a motility-recovery agent after gastrectomy in humans.

Sleep-disordered breathing (SDB) is highly prevalent in the general population and has been associated with cognitive impairment in older individuals. Delirium is an acute decline in cognitive function and attention that often occurs after surgery, especially in older individuals. Several recent studies suggest an association between SDB and postoperative delirium. The aim of this systematic review is to examine the current literature on SDB, postoperative delirium, and cognitive impairment and to discuss the pathophysiology and perioperative considerations. A literature search was performed of Medline (1946-2016), Medline In-Process (June 2016), Embase (1947-2016), Cochrane Central Register of Controlled Trials (May 2016), and Cochrane Database of Systematic Reviews (2005 to June 2016). Inclusion criteria for studies were (1) polysomnography confirmed SDB; (2) postoperative delirium or cognitive impairment confirmed by a validated diagnostic tool; and (3) publications in the English language. All study designs including randomized controlled trials and observational studies were included. The literature search identified 2 studies on SDB and postoperative delirium, 15 studies on SDB and cognitive impairment, and 5 studies on the effect of continuous positive airway pressure on cognitive impairment and delirium in older individuals. SDB was associated with cognitive impairment, and this systematic review revealed that SDB may be a risk factor for postoperative delirium, especially in older individuals. Although the pathophysiology of SDB and postoperative delirium is unclear and effective treatments for SDB to reduce the incidence of delirium have not been studied extensively, preliminary evidence suggests that continuous positive airway pressure therapy may lower the risk of delirium. Health care professionals need to be aware that undiagnosed SDB may contribute to postoperative delirium. Preoperative screening for SDB and strategies to reduce the risk for

We evaluate the impact of extent of surgery (EOS) on survival of patients with supratentorial nonpilocytic low-grade gliomas (LGG) treated with postoperative radiation therapy (PORT). Sixty-five patients with pathologically confirmed supratentorial nonpilocytic LGG (36 astrocytomas and 29 oligodendrogliomas) were treated with PORT after different extents of surgery: 12 gross total resections (GTR), 27 minimal or subtotal resections (MR/SR), and 26 biopsies (B). EOS was confirmed with postoperative imaging. The median radiation dose delivered was 5,940 cGy (range, 4,950-6,620 cGy). One of 12 patients (8%) in the GTR group and 12 of 53 patients (23%) in the less than GTR group demonstrated contrast enhancement. The median follow-up was 61 months (range 5-194 month). The 10-year overall survival (OS) was 82.5% and 32% for the GTR and the less than GTR groups, respectively (P = 0.0008). The corresponding 10-year disease-specific survival (DSS) was 90% and 41.4%%, respectively (P = 0.001). Multivariate analysis showed that only contrast enhancement and EOS were predictors for OS and DSS. Our data suggest that EOS correlates with OS and DSS in patients who have PORT. GTR should be the goal if technically achievable without causing significant morbidity, and its combination with PORT is compatible with long-term survival. Copyright 2002 Wiley-Liss, Inc.

Paralytic ileus that develops after elective surgery is a common and uncomfortable complication and is considered inevitable after an intraperitoneal operation. The purpose of this study was to investigate whether coffee consumption accelerates the recovery of bowel function after complete staging surgery of gynecologic cancers. In this randomized controlled trial, 114 patients were allocated preoperatively to either postoperative coffee consumption with 3 times daily (n=58) or routine postoperative care without coffee consumption (n=56). Total abdominal hysterectomy and bilateral salpingo-oophorectomy with systematic pelvic and paraaortic lymphadenectomy were performed on all patients as part of complete staging surgery for endometrial, ovarian, cervical, or tubal cancer. The primary outcome measure was the time to the first passage of flatus after surgery. Secondary outcomes were the time to first defecation, time to first bowel movement, and time to tolerance of a solid diet. The mean time to flatus (30.2±8.0 vs 40.2±12.1 hours; P<.001), mean time to defecation (43.1±9.4 vs 58.5±17.0 hours; P<.001), and mean time to the ability to tolerate food (3.4±1.2 vs 4.7±1.6 days; P<.001) were reduced significantly in patients who consumed coffee compared with control subjects. Mild ileus symptoms were observed in 17 patients (30.4%) in the control group compared with 6 patients (10.3%) in the coffee group (P=.01). Coffee consumption was well-tolerated and well-accepted by patients, and no intervention-related side-effects were observed. Coffee consumption after total abdominal hysterectomy and systematic paraaortic lymphadenectomy expedites the time to bowel motility and the ability to tolerate food. This simple, cheap, and well-tolerated treatment should be added as an adjunct to the postoperative care of gynecologic oncology patients. Copyright © 2016 Elsevier Inc. All rights reserved.

Studies suggest Asian Americans may have improved oncologic outcomes compared with other ethnicities. We hypothesized that Asian Americans with colorectal cancer would have improved surgical outcomes in mortality, postoperative complications (POCs), length of stay (LOS), and readmissions compared with other racial/ethnic groups. We queried the 2011-2014 American College of Surgeons National Surgical Quality Improvement Program for patients who underwent surgery for colorectal cancer and stratified patients by race. Primary outcome was 30-d mortality with secondary outcomes including POCs, LOS, and 30-d readmission. Stepwise backward logistic regression analyses and incident rate ratio calculations were performed to identify risk factors for disparate outcomes. Of the 28,283 patients undergoing colorectal surgery for malignancy, racial/ethnic groups were divided into Caucasian American (84%), African American (12%), or Asian American (4%). On unadjusted analyses, compared with other racial/ethnic groups, Asian Americans were more likely to have normal weight, not smoke, and had lower American Society of Anesthesiologists score of 1 or 2 (P < 0.001). Postoperatively, Asian Americans had the shortest LOS and the lowest rates of complications due to ileus, respiratory, and renal complications (P < 0.001). There were no racial differences in 30-d mortality or readmission. On adjusted analyses, Asian American race was independently associated with less postoperative ileus (odds ratio 0.8, 95% confidence interval 0.66-0.98, P < 0.001) and decreased LOS by 13% and 4% compared with African American and Caucasian American patients, respectively (P < 0.001). Asian Americans undergoing surgery for colorectal cancer have shorter LOS and fewer POCs when compared with other racial/ethnic groups without differences in 30-d mortality or readmissions. The mechanism(s) underlying these disparities will require further study, but may be a result of patient, provider, and

To investigate risk factors to predict postoperative fever after endovascular treatment of ruptured intracranial aneurysms. Patients undergoing endovascular coiling to treat subarachnoid hemorrhage in Nantong University between November 2011 and September 2014 were retrospectively reviewed. Postoperative temperature and patient demographic data, admission status, characteristic features of aneurysms, and endovascular coiling procedure were documented and analyzed. There were 336 consecutive patients included in this study, and 111 were classified as febrile (tympanic temperature >38.3°C for at least 2 consecutive days). Univariate analysis demonstrated that age, interval from onset of subarachnoid hemorrhage to operation, history of hypertension and smoking, Hunt and Hess grade, Fisher grade, temperature before coiling, leukocyte count on admission, and infectious complications were correlated with postoperative fever. Five variables were independent risk factors to predict fever by multivariate logistic regression: age >70 years (odds ratio [OR] = 2.6, 95% confidence interval [CI] = 1.2-5.6), Fisher grade 3 or 4 (OR = 2.2, 95% CI = 1.1-4.3), leukocyte count >10,000/mm(3) on admission (OR = 2.3, 95% CI = 1.3-4.0), temperature >37.5°C before coiling (OR = 4.6, 95% CI = 2.0-10.7), and infectious complications (OR = 4.4, 95% CI = 2.2-8.6). Postoperative fever after coil embolization was predicted by changeable and unchangeable risk factors in subarachnoid hemorrhage. However, characteristic features of aneurysms and the coiling procedure had no impact on development of postoperative fever. Preventing any infectious complications, lowering temperature before embolization, and draining bloody cerebrospinal fluid may assist in the prevention of subsequent fever.

Impact of duloxetine and dexamethasone for improving postoperative pain after laparoscopic gynecological surgeries: A randomized clinical trial

PubMed Central

Kassim, Dina Y.; Esmat, Ibrahim M.; Elgendy, Mohammed A.

2018-01-01

Background: Patients’ surgical experiences are influenced by their perception of pain management. Duloxetine (Dulox) and dexamethasone (Dex) are used in multimodal analgesia to reduce opioid use and side effects. Dulox is a selective serotonin and norepinephrine reuptake inhibitor and has efficacy in chronic pain conditions. Dex enhances postoperative (PO) analgesia and reduces PO nausea and vomiting (PONV). Methods: Seventy-five female patients were randomly allocated into one of three equal groups. GI received Dulox 60 mg orally and 100 ml 0.9% sodium chloride (normal saline [NS]) intravenous infusion (IVI) over 15 min, GII: received as GI except Dex 0.1 mg/kg was mixed with NS and GIII received identical placebo for Dulox capsule and Dex IVI, 2 h preoperatively. Patients’ vitals, visual analog scale (VAS), and sedation score were assessed at 30 min, 1 h, 2 h, 6 h, and 12 h postoperatively. Total pethidine requirements, plasma cortisol, PONV, and patients satisfaction were recorded. Results: PO time for 1st rescue analgesic was significantly high in GI and GII compared to GIII and in GII compared to GI. There was a significant less VAS score, heart rate, mean arterial pressure, and a high sedation score in GI and GII compared to GIII at 30 min, 1, 2, and 6 h postoperatively. Total pethidine requirements were significantly less in GI and GII compared to GIII 12 h postoperatively. There was a significant reduction in the 2 h PO serum cortisol (μg/dl) and a significant increase in the PO patients satisfaction score in GI and GII compared to GIII. PONV was decreased significantly in GII compared to GI and GIII. Conclusion: The use of oral Dulox 60 mg combined with Dex 0.1 mg/kg IVI is more effective than oral Dulox 60 mg alone, 2 h preoperatively, for improving PO pain by reducing the requirements for rescue analgesia and PONV.

Cystic fibrosis (CF) is a monogenic disease due to mutations in the CFTR gene. Yet, variability in CF disease presentation is presumed to be affected by modifier genes, such as those recently demonstrated for the pulmonary aspect. Here, we conduct a modifier gene study for meconium ileus (MI), an intestinal obstruction that occurs in 16–20% of CF newborns, providing linkage and association results from large family and case–control samples. Linkage analysis of modifier traits is different than linkage analysis of primary traits on which a sample was ascertained. Here, we articulate a source of confounding unique to modifier gene studies and provide an example of how one might overcome the confounding in the context of linkage studies. Our linkage analysis provided evidence of a MI locus on chromosome 12p13.3, which was segregating in up to 80% of MI families with at least one affected offspring (HLOD = 2.9). Fine mapping of the 12p13.3 region in a large case–control sample of pancreatic insufficient Canadian CF patients with and without MI pointed to the involvement of ADIPOR2 in MI (p = 0.002). This marker was substantially out of Hardy–Weinberg equilibrium in the cases only, and provided evidence of a cohort effect. The association with rs9300298 in the ADIPOR2 gene at the 12p13.3 locus was replicated in an independent sample of CF families. A protective locus, using the phenotype of no-MI, mapped to 4q13.3 (HLOD = 3.19), with substantial heterogeneity. A candidate gene in the region, SLC4A4, provided preliminary evidence of association (p = 0.002), warranting further follow-up studies. Our linkage approach was used to direct our fine-mapping studies, which uncovered two potential modifier genes worthy of follow-up. PMID:19662435

Pyoderma gangrenosum (PG) is an uncommon inflammatory ulcerative skin disease. It is characterized by painful progressive necrosis of the wound margins. Rarely, postoperative pyoderma gangrenosum (PPG) manifests as a severe disturbance of wound healing following surgical interventions. Only rare cases of this complication have been reported after appendectomy. We report a case of PPG in a 29-year-old female after appendectomy. She was successfully treated with oral prednisolone. Postoperative pyoderma gangrenosum should be kept in mind in the differential diagnosis of any postoperative delayed wound healing, because this disease is simply distinguished from a postoperative wound.

Much attention in the volume-outcomes literature has focused on the empirical impact of surgical caseload on outcomes. However, relevant studies on the association between surgical volume and variables that potentially contribute to healthcare costs are limited. The objective of this study was to systematically elucidate a contemporary analysis of the empirical relationship between hospital esophagectomy volume and postoperative length of stay, a cost-related outcome. OvidSP, PubMed, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), ISI Web of Science and OpenGrey were searched for relevant articles published from 2000 to 2016. High hospital esophagectomy volume was associated with reduced postoperative length of stay (mean: 3 days; 95%CI: 2.8, 3.2) and risk of prolonged length of stay (RR: 0.80, 95%CI: 0.74, 0.87) in a dose-response fashion. Complex surgeries performed at high surgical volume centers may be associated with overall decrease in postoperative length of stay, a cost-related outcome. Copyright © 2017 Elsevier Inc.

Roberge, C W; McEwen, M

1998-12-01

This study was performed to determine if intraoperative local anesthesia improved control of postoperative pain after inguinal herniorrhaphy and to compare the effects of two commonly used local anesthetics on pain management. The Gate Control Theory of Pain formed the theoretical basis for this study. A retrospective nonexperimental study in an ex post facto design was used. Data were collected from 1990 through 1997 on 120 patient charts. The use of local anesthetic intraoperatively significantly decreased patients' lengths of stay postoperatively (P = 0.00) and need for postoperative narcotics (P = 0.00). Bupivacaine was found to be superior to lidocaine in decreasing the need for postoperative narcotic analgesia. Researchers concluded that many patients would benefit from intraoperative injection of local anesthesia. This information can affect patient care outcomes through decreasing recovery time, reducing postoperative pain, and reducing health care costs.

In patients seeking aesthetic rhinoplasty, a high prevalence of body dysmorphic disorder symptoms has recently been reported. However, the impact of these symptoms on the outcomes after rhinoplasty remains elusive. This large-scale study determines the influence of preoperative body dysmorphic disorder symptoms on patients' postoperative satisfaction and quality of life, using validated questionnaires. A 1-year prospective study of 166 adult patients undergoing cosmetic rhinoplasty in a tertiary referral center was performed. Severity of body dysmorphic disorder symptoms was assessed by the modified Yale-Brown Obsessive Compulsive Scale. Postoperative satisfaction was evaluated using a visual analog scale for patients' appraisal of nasal shape and the Rhinoplasty Outcome Evaluation. Generic quality of life was quantified by the Sheehan Disability Scale, whereas the appearance-related disruption of everyday life was measured by the Derriford Appearance Scale-59. Preoperative body dysmorphic disorder symptom scores inversely correlated with postoperative satisfaction at 3 months (visual analog scale nasal shape: rho = -0.43, p < 0.001; Rhinoplasty Outcome Evaluation: rho = -0.48, p < 0.001) and 12 months (rho = -0.40, p < 0.001; and rho = -0.41, p < 0.001, respectively) after surgery. In addition, body dysmorphic disorder symptom scores positively correlated with Sheehan Disability Scale scores and Derriford Appearance Scale-59 scores at 3 months (rho = 0.43, p < 0.001 and rho = 0.48, p < 0.001, respectively) and 12 months (rho = 0.32, p < 0.001, and rho = 0.48, p < 0.001, respectively) postoperatively. This study provides the first evidence of the negative impact of preoperative body dysmorphic disorder symptoms on subjective outcomes after rhinoplasty, hence unveiling a crucial factor in patient dissatisfaction after aesthetic rhinoplasty.

Eleven patients with dysphagia caused by severe esophageal stricture (length 2 to 10 cm) resulting from reflux esophagitis were treated with fibroendoscopic dilation (Eder-Puestow) and Roux-en-Y partial gastrectomy with vagotomy during 10 years (1979 to 1988). There was no operative mortality, but complications developed in three patients: One patient had a mediastinal abscess demanding thoracotomy as a result of esophageal perforation after dilatation; one had postoperative pneumonia; and one patient had ileus. After a mean follow-up of 4 years (range 1 to 10 years) esophagitis healed in all cases, as judged by endoscopy. Eight patients were asymptomatic, but three had slight transient dysphagia. Postoperatively one to eight dilations (average three to four) were needed to relieve dysphagia in the first postoperative year, but later the stricture healed in every case. Postoperative pH measurement was performed in six latest patients and showed complete absence of reflux in all cases. It is concluded that Roux-en-Y partial gastrectomy with vagotomy and endoscopic dilation is an effective, simple, and safe procedure in the management of severe peptic esophageal (acid or alkaline esophagitis) stricture. However, occasional postoperative dilations at the outpatient clinic are often needed in severe cases in the first postoperative year.

In recent years, thoracic wall nerve blocks, such as the pectoral nerve (PECS) block and the serratus plane block have become popular for peri-operative pain control in patients undergoing breast cancer surgery. The effect of PECS block on quality of recovery (QoR) after breast cancer surgery has not been evaluated. To evaluate the ability of PECS block to decrease postoperative pain and anaesthesia and analgesia requirements and to improve postoperative QoR in patients undergoing breast cancer surgery. Randomised controlled study. A tertiary hospital. Sixty women undergoing breast cancer surgery between April 2014 and February 2015. The patients were randomised to receive a PECS block consisting of 30 ml of levobupivacaine 0.25% after induction of anaesthesia (PECS group) or a saline mock block (control group). The patients answered a 40-item QoR questionnaire (QoR-40) before and 1 day after breast cancer surgery. Numeric Rating Scale score for postoperative pain, requirement for intra-operative propofol and remifentanil, and QoR-40 score on postoperative day 1. PECS block combined with propofol-remifentanil anaesthesia significantly improved the median [interquartile range] pain score at 6 h postoperatively (PECS group 1 [0 to 2] vs. Control group 1 [0.25 to 2.75]; P = 0.018]. PECS block also reduced propofol mean (± SD) estimated target blood concentration to maintain bispectral index (BIS) between 40 and 50 (PECS group 2.65 (± 0.52) vs. Control group 3.08 (± 0.41) μg ml; P < 0.001) but not remifentanil consumption (PECS group 10.5 (± 4.28) vs. Control group 10.4 (± 4.68) μg kg h; P = 0.95). PECS block did not improve the QoR-40 score on postoperative day 1 (PECS group 182 [176 to 189] vs. Control group 174.5 [157.75 to 175]). In patients undergoing breast cancer surgery, PECS block combined with general anaesthesia reduced the requirement for propofol but not that for remifentanil, due to the inability of the PECS block to reach

The aim of our study was the early detection and treatment of patients with unknown alterations of the hydrocarbon metabolism subject to total knee arthroplasty in order to reduce the incidence of postoperative complications. Patients were classified as non-diabetic patients (group 1), diabetic patients (group 2) and patients with stress hyperglycaemia (group 3). The last two groups were recommended assessment by a primary care physician (PCP). After one year follow-up the groups were compared with respect to incidence of postoperative complications. The groups were also compared regarding the decrease or increase of HbA1c levels with the incidence of complications. Of the 228 patients, 116 (50%) were included in group 1, 40 (17.5%) in group 2 and 72 (31.6%) in group 3. Patients that consulted their PCP presented lower medical complication rates than those who did not (9.2% vs. 26.4%, P=0.020). Not being attended by a PCP was an independent predictive factor of medical complication (odds ratio (OR): 21.3; 95% confidence interval (95% CI): 4.6-98.5), surgical site infection (OR: 4.1; 95% CI: 1.1-15.0) and mechanical complication (OR: 5.0; 95% CI: 1.3-18.8). A decrease of HbA1c value was related to less medical systemic complications (7.3% vs. 24.2%, P=0.035). Patients with hyperglycaemia during the postoperative total knee arthroplasty period, who are controlled by the PCP present lower incidence of complications. Decrease of HbA1c value during postoperative total knee arthroplasty period leads to a lower rate of medical complications. Copyright © 2016 Elsevier B.V. All rights reserved.

Despite extensive research in the international arena into pain and its management, there is, as yet, little research on the topic of pain in children in Saudi Arabia and in the Gulf countries generally. A systematic review was conducted to explore the impact of education programs on factors affecting paediatric nurses' postoperative pain management practice. This was done in order to advise the creation of an educational program for nurses in Saudi Arabia. Knowledge about pain, attitudes towards pain, beliefs about children's pain, perceptions of children's reports of pain, self-efficacy with regard to pain management, and perceptions of barriers to optimal practice were all considered to be relevant factors. The review was restricted to randomized controlled trials and quasi-experimental designs, excluding studies focussed on chronic pain or populations other than solely children. Studies published in English between 2000 and 2016 were identified using CINAHL, MEDLINE, Ovid SP, The Cochrane Library, ProQuest, and Google Scholar databases. Of 499 published studies identified by the search, 14 met the inclusion criteria and were included in the review. There was evidence of educational programs exerting a postive impact on enhancing pediatric nurses' knowledge of pain and modifing their attitudes towards it, but only limited evidence was available about the impact on nurses' beliefs and perceptions of children's reports of pain, nurses' self-efficacy, or barriers to optimal practice. None of the studies was conducted in Saudi Arabia. Studies were needed to address additional aspects of preparedness for effective postperative pain management. Details of educational programs used as experimental intervention must be included in reports.

BACKGROUND Hip and knee arthroplasty infections are associated with considerable healthcare costs. The merits of reducing the postoperative surveillance period from 1 year to 90 days have been debated. OBJECTIVES To report the first pan-Canadian hip and knee periprosthetic joint infection (PJI) rates and to describe the implications of a shorter (90-day) postoperative surveillance period. METHODS Prospective surveillance for infection following hip and knee arthroplasty was conducted by hospitals participating in the Canadian Nosocomial Infection Surveillance Program (CNISP) using standard surveillance definitions. RESULTS Overall hip and knee PJI rates were 1.64 and 1.52 per 100 procedures, respectively. Deep incisional and organ-space hip and knee PJI rates were 0.96 and 0.71, respectively. In total, 93% of hip PJIs and 92% of knee PJIs were identified within 90 days, with a median time to detection of 21 days. However, 11%-16% of deep incisional and organ-space infections were not detected within 90 days. This rate was reduced to 3%-4% at 180 days post procedure. Anaerobic and polymicrobial infections had the shortest median time from procedure to detection (17 and 18 days, respectively) compared with infections due to other microorganisms, including Staphylococcus aureus. CONCLUSIONS PJI rates were similar to those reported elsewhere, although differences in national surveillance systems limit direct comparisons. Our results suggest that a postoperative surveillance period of 90 days will detect the majority of PJIs; however, up to 16% of deep incisional and organ-space infections may be missed. Extending the surveillance period to 180 days could allow for a better estimate of disease burden. Infect Control Hosp Epidemiol 2017;38:147-153.

As the population ages, increasing numbers of older adults are undergoing surgery. Frailty is prevalent in older adults and may be a better predictor of post-operative morbidity and mortality than chronological age. The aim of this review was to examine the impact of frailty on adverse outcomes in the 'older old' and 'oldest old' surgical patients. A systematic review was undertaken. Electronic databases from 2010 to 2015 were searched to identify articles which evaluated the relationship between frailty and post-operative outcomes in surgical populations with a mean age of 75 and older. Articles were excluded if they were in non-English languages or if frailty was measured using a single marker only. Demographic data, type of surgery performed, frailty measure and impact of frailty on adverse outcomes were extracted from the selected studies. Quality of the studies and risk of bias was assessed by the Epidemiological Appraisal Instrument. Twenty-three studies were selected for the review and they were assessed as medium to high quality. The mean age ranged from 75 to 87 years, and included patients undergoing cardiac, oncological, general, vascular and hip fracture surgeries. There were 21 different instruments used to measure frailty. Regardless of how frailty was measured, the strongest evidence in terms of numbers of studies, consistency of results and study quality was for associations between frailty and increased mortality at 30 days, 90 days and one year follow-up, post-operative complications and length of stay. A small number of studies reported on discharge to institutional care, functional decline and lower quality of life after surgery, and also found a significant association with frailty. There was strong evidence that frailty in older-old and oldest-old surgical patients predicts post-operative mortality, complications, and prolonged length of stay. Frailty assessment may be a valuable tool in peri-operative assessment. It is possible that

Background Limited communication and care coordination following discharge from hospitals may contribute to surgical complications. Smartphone apps offer a novel mechanism for communication and care coordination. However, factors which may affect patient app use in a postoperative, at-home setting are poorly understood. Objective The objectives of this study were to (1) gauge interest in smartphone app use among patients after colorectal surgery and (2) better understand factors affecting patient app use in a postoperative, at-home setting. Methods A prospective feasibility study was performed at a hospital that principally serves low socioeconomic status patients. After colorectal surgery, patients were enrolled and given a smartphone app, which uses previously validated content to provide symptom-based recommendations. Patients were instructed to use the app daily for 14 days after discharge. Demographics and usability data were collected at enrollment. Usability was measured with the System Usability Scale (SUS). At follow-up, the SUS was repeated and patients underwent a structured interview covering ease of use, willingness to use, and utility of use. Two members of the research team independently reviewed the field notes from follow-up interviews and extracted the most consistent themes. Chart and app log reviews identified clinical endpoints. Results We screened 115 patients, enrolled 20 patients (17.4%), and completed follow-up interviews with 17 patients (85%). Reasons for nonenrollment included: failure to meet inclusion criteria (47/115, 40.9%), declined to participate (26/115, 22.6%), and other reasons (22/115, 19.1%). There was no difference in patient ratings between usability at first-use and after extended use, with SUS scores greater than the 95th percentile at both time points. Despite high usability ratings, 6/20 (30%) of patients never used the app at home after hospital discharge and 2/20 (10%) only used the app once. Interviews revealed three

Under-treatment of acute postoperative pain can lead to chronic pain with neuronal plasticity and result in poor surgical outcomes. A multimodal approach is therefore necessary to reduce postoperative pain by combining various analgesics with a non-pharmacological strategy. The current use of multimodal approaches, even for the management of postoperative pain, can reduce the side effects of pharmaceutical therapy alone as well as reducing the length of hospital stay. Adequate pain control is an important prerequisite for the application of rehabilitation programmes and will thereby influence functional outcome. In addition, patient satisfaction, as a major benchmarking factor after surgical treatment, is significantly influenced by the quality of postoperative pain management.

Though postoperative radiation for esophageal squamous cell carcinoma is offered in selected cases, there is conflicting evidence as to whether it improves overall survival (OS). A retrospective investigation was performed to analyze the prognostic impact of postoperative radiation therapy (PORT) in a large cohort of patients. From 2001 to 2009, 725 patients underwent radical esophagectomy (R0) with or without PORT were eligible for retrospective analysis. Patients were grouped into surgery alone (n = 467) and surgery plus PORT (n = 258). Median irradiation doses were 50 Gy (range: 40-56 Gy). Radiation fields encompassed the bilateral supraclavicular fossa, mediastinum, subcarinal area, and the tumor bed for the upper/middle-third disease; the bilateral supraclavicular fossa, mediastinum, the tumor bed, subcarinal area, and lower thoracic paraesophageal area for the lower-third disease. Kaplan-Meier and Cox regression analysis were used to compare OS. After median follow-up of 53 months, the median OS was 29 months in the PORT group and 23 months in the surgery alone group. The addition of PORT improved OS at 3 years from 36.6 to 43.6% compared with surgery alone. The use of PORT was associated with significantly improved OS (p = 0.018). For American Joint Committee on Cancer (AJCC) stage III esophageal cancer (T1-2N2M0, T3N1-2M0, T4N1-3M0), there was significant improvement in OS (p = 0.002) in the PORT group, not only for lymph-node metastatic ratio (LNMR) ≥0.25 (p = 0.001), but also for LNMR <0.25 (p = 0.043). However, for stage IIB disease (T1-2N1M0) there was no significant differences. The addition of POCT didn't prolong the OS significantly (Surgery alone group, p = 0.079; PORT group, p = 0.111). This large retrospective analysis supports the use of PORT for pathologic lymph node positive stage III esophageal squamous cell carcinoma. Given the retrospective nature of this study, the results should be confirmed by appropriately powered randomized trials

To investigate the feasibility of continuation of aspirin before tooth extraction in the elderly. The patients enrolled in this study were the elderly requiring a single non-impacted tooth extraction. 300 elderly outpatients used lidocaine local infiltration anesthesia, 200 patients without using aspirin before tooth extraction served as control group I, 100 patients with prolong use of aspirin before tooth extraction as observation group I. 300 elderly outpatients used compound articaine local infiltration anesthesia, 200 patients without using aspirin before tooth extraction served as control group II, 100 patients with prolong use of aspirin before tooth extraction as observation group II.Bleedings at 5, 10, 30 min, 24 h after tooth extraction were observed and the relationship between postoperative bleeding and intake of aspirin was analyzed. There was no significant difference at 5, 10, 30 min, 24 h in postoperative bleeding after extraction between control group I and observation group. The incidence of bleeding of observation group II after tooth extraction at 5 min was higher than that of control group II and there was no significant difference at 10, 30 min, 24 h between the two groups. Continuation of aspirin have no influence on postoperative bleeding. Therefore we suggest that there was no indication to discontinue aspirin for the elderly before a single non-impacted tooth extraction.

To develop new technique of abdominal wall repair for postoperative ventral hernia without disadvantages which are intrinsic for open and laparoscopic surgery. Combined open and laparoscopic hernia repair was used in 18 patients with postoperative ventral hernia. Open stage provided safe dissection of abdominal adhesions and defect closure by autoplasty, laparoscopic procedure consisted of prosthesis deployment without separation of abdominal wall layers. Two types of composite endoprostheses with anti-adhesive coating were used for abdominal wall repair. There were no cases of recurrence or infectious complications in long-term period (from 3 to 106 months). Hybrid repair of postoperative ventral hernia is safe and effective procedure. Further studies are necessary to assess cost-effectiveness ratio of this method in view of expensive composite endoprostheses and laparoscopic supplies.

Data about prognostic value of postoperative fever in gastric cancer was lacking. Thus, the present study aims to investigate the prognostic value of postoperative fever in gastric cancer. From September 2008 to March 2015, 2938 gastric cancer patients were enrolled in the present study. Clinicopathological features were recoded. The association between postoperative fever and prognosis of gastric cancer were analyzed. There were 2294 male (78.1%) and 644 female (21.9%). Seven hundred and fifty-six patients suffered from fever. Among them, the duration of fever less than 48h occurred in 508 cases, and duration of fever over 48h occurred in 248 cases. Univariate and multivariate analysis showed that postoperative fever was an independent risk factor for prognosis of gastric cancer ( P < 0.001). For the entire cohort, duration of fever over 48h was significantly associated with decreased survival ( P < 0.001). In subgroup analysis, duration of fever over 48h was significantly associated with poor prognosis of stage I and II gastric cancer (both P < 0.001). However, postoperative fever was not associated with the prognosis of stage III gastric cancer ( P = 0.334). Considering the type of gastrectomy, postoperative fever was not associated with the prognosis of patients with proximal ( P = 0.318) and distal gastrectomy ( P = 0.806), but duration of fever over 48h was significantly associated with poor prognosis of patients with total gastrectomy ( P = 0.004). In conclusion, postoperative fever was associated with poor prognosis of gastric cancer.

Face lift postoperative recovery.

Mottura, A Aldo

2002-01-01

The purpose of this paper is to describe what I have studied and experienced, mainly regarding the control and prediction of the postoperative edema; how to achieve an agreeable recovery and give positive support to the patient, who in turn will receive pleasant sensations that neutralize the negative consequences of the surgery.After the skin is lifted, the drainage flow to the flaps is reversed abruptly toward the medial part of the face, where the flap bases are located. The thickness and extension of the flap determines the magnitude of the post-op edema, which is also augmented by medial surgeries (blepharo, rhino) whose trauma obstruct their natural drainage, increasing the congestion and edema. To study the lymphatic drainage, the day before an extended face lift (FL) a woman was infiltrated in the cheek skin with lynfofast (solution of tecmesio) and the absorption was observed by gamma camera. Seven days after the FL she underwent the same study; we observed no absorption by the lymphatic, concluding that a week after surgery, the lymphatic network was still damaged. To study the venous return during surgery, a fine catheter was introduced into the external jugular vein up to the mandibular border to measure the peripheral pressure. Following platysma plication the pressure rose, and again after a simple bandage, but with an elastic bandage it increased even further, diminishing considerably when it was released. Hence, platysma plication and the elastic bandage on the neck augment the venous congestion of the face. There are diseases that produce and can prolong the surgical edema: cardiac, hepatic, and renal insufficiencies, hypothyroidism, malnutrition, etc. According to these factors, the post-op edema can be predicted, the surgeon can choose between a wide dissection or a medial surgery, depending on the social or employment compromises the patient has, or the patient must accept a prolonged recovery if a complex surgery is necessary.

Ambulance organisations in Sweden have introduced prehospital fast track care (PFTC) for patients with suspected hip fracture. This means that the ambulance nurse starts the pre-operative procedure otherwise implemented at the accident & emergency ward (A&E) and transports the patient directly to the radiology department instead of A&E. If the diagnosis is confirmed, the patient is transported directly to the orthopaedic ward. No previous randomised, controlled studies have analysed PFTC to describe its possible advantages. The aim of this study is to examine whether PFTC has any impact on outcomes such as time to surgery, length of stay, post-operative complications and mortality. The design of this study is a prehospital randomised, controlled study, powered to include 400 patients. The patients were randomised into PFTC or the traditional care pathway (A&E group). Time from arrival to start for X-ray was faster for PFTC (mean, 28 vs. 145 min; p<0.001), but the groups did not differ with regard to time from start of X-ray to start of surgery (mean 18.40 h in both groups). No significant differences between the groups were observed with regard to: time from arrival to start of surgery (p=0.07); proportion operated within 24h (79% PFTC, 75% A&E; p=0.34); length of stay (p=0.34); post-operative complications (p=0.75); and 4 month mortality (18% PFTC, 15% A&E p=0.58). PFTC improved time to X-ray and admission to a ward, as expected, but did not significantly affect time to start of surgery, length of stay, post-operative complications or mortality. These outcomes were probably affected by other factors at the hospital. Patients with either possible life-threatening conditions or life-threatening conditions prehospital were excluded.

A total of 109 maintenance hemodialysis patients underwent major operations. Anuria was defined as urine output <30 mL in the 8 hours before the first session of postoperative dialysis. Propensity scores for postoperative anuria were developed. Postoperative residual urine output was 159.2 mL/8 h (SD, 115.1) in 33 patients; 76 patients were anuric. Preoperative residual urine output and adequate perioperative blood transfusion were positively related to postoperative urine output. Propensity-adjusted 30-day mortality was associated with postoperative anuria (odds ratio [OR], 4.56; 95% confidence interval [CI], 1.16-17.96; P = .03), prior stroke (OR, 4.46; 95% CI, 1.43-13.89; P = .01) and higher disease severity (OR, 1.10; 95% CI, 1.00-1.21; P = .049) at the first postoperative dialysis. OR of 30-day mortality was 5.38 for nonanuria to anuria vs nonanuria to nonanuria (P = .03) and 5.13 for preoperative anuria vs nonanuria to nonanuria (P = .01). By Kaplan-Meier analysis, 30-day mortality differed significantly among patients for nonanuria to nonanuria, anuria, and nonanuria to anuria (log rank, P = .045). Patients with preoperative nonanuria and postoperative anuria had higher mortality than did patients with no anuria before and after surgery and patients with anuria before surgery. Postoperative residual urine output is an important surrogate marker for disease severity.

To evaluate the long-term impact of bilateral cataract surgery on postoperative complications, influence of age at surgery on the pattern of axial growth and central corneal thickness (CCT), and visual and orthoptic assessment in microphthalmic eyes. Iladevi Cataract and IOL Research Centre, Ahmedabad, India. Prospective longitudinal study. This study assessed children with microphthalmos who had bilateral congenital cataract surgery. Microphthalmos was defined as an eye that has an axial length (AL) that was 2 standard deviations smaller than what is normally expected at that age. All eyes were left aphakic. One of the 2 eyes was randomly selected for analysis. Postoperative complications, AL, CCT, and visual acuity were documented. This study included 72 eys of 36 children. The mean age of the patients was 4.8 months ± 6.2 (SD) (range 0.5 to 15 months). Postoperative complications included secondary glaucoma (11/36, 30.6%), visual axis obscuration (4/36, 11.1%), and posterior synechiae (10/36, 27.8%). A significant rate of change was observed in axial growth up to 4 years and in CCT up to 3 years postoperatively. When age at the time of surgery was correlated with the profile of the rate of change in AL and CCT at 1 month and 1, 2, and 4 years, statistically significant differences in AL and CCT at all timepoints were found. Loss of vision after surgery occurred in 2 eyes. After early surgical intervention, an acceptable rate of serious postoperative complications and good visual outcomes were obtained in microphthalmic eyes.

A single-subject study of two methods of postoperative ambulation of patients recovering from thoracic surgery. During the postoperative setting, patients are often burdened by their condition that reduces their ability to ambulate. This problem is compounded by the addition of devices that make walking more cumbersome. To simplify the process of ambulation during the postoperative period, an intravenous pole/walker (IVPW) was specifically designed to allow all patient devices and attachments to accompany the patient during ambulation, without the need for supplemental caregiver assistance. The IVPW method of ambulation was compared with standard method of ambulation (SMA) in a single-subject clinical trial. Thirty-nine consecutive thoracic surgery patients with at least an IV and chest tube were ambulated using alternatively either the IVPW or the SMA. Immediately following the ambulation periods, the patient and patient's health care worker assessed both methods using satisfaction surveys consisting of several questions about the episodes of ambulation and the number of health care workers needed to assist during ambulation. Patient satisfaction was significantly higher in the ability of the IVPW to provide support and assist in ambulation in comparison with the SMA (p < 0·001). Nurses felt the IVPW both facilitated and provided a safer method for ambulation compared with the SMA (p < 0·001). On average, one less employee was required during ambulation with the IVPW (p < 0·001). The IVPW provided better support and was perceived as a safer method for ambulation compared with the SMA. The IVPW also required one less person to assist with ambulation. Facilitation of ambulation in the postoperative setting can impact nursing care and patient satisfaction. © 2012 The Authors.

Recently published data show that postoperative apnea-hypopnea index (AHI) is significantly increased in some patients without preoperative sleep apnea. These patients may be at risk of developing perioperative adverse events related to sleep-disordered breathing (SDB). The objective of this study was to investigate the incidence and predictors of postoperative moderate-to-severe SDB (AHI > 15 events/h) in patients without sleep apnea preoperatively. In a prospective observational fashion, patients were invited to undergo sleep studies with a portable device (Embletta X100) preoperatively at home and postoperatively on the first and third night after surgery in the hospital or at home. The primary outcome was the incidence of postoperative moderate-to-severe SDB (AHI > 15 events/h) in non-sleep apnea patients (preoperative AHI ≤ 5 events/h). Logistic regression was used to evaluate the association of clinical factors and preoperative sleep parameters with the occurrence of postoperative moderate-to-severe SDB. A total of 120 non-sleep apnea patients completed the study, of which 31 (25.8% [95% confidence interval: 18.3%-34.6%]) patients were found to have AHI > 15 events/h on postoperative night 1 and/or postoperative night 3 (postoperative SDB group), and 89 (74%) patients had an AHI ≤ 15 events/h on both postoperative night 1 and 3 (postoperative non-SDB group). The patients in the postoperative SDB group were older (60 ± 13 vs 53 ± 12 years, P = 0.008) with more smokers (32.3% vs 15.7%, P = 0.048) and had a greater increase in the obstructive apnea index (adjusted P = 0.0003), central apnea index (adjusted P = 0.0012), and hypopnea index (adjusted P = 0.0004). Multivariate logistic regression analysis found that age and preoperative respiratory disturbance index (RDI) were significantly associated with the occurrence of postoperative moderate-to-severe SDB, P = 0.018 and P = 0.006, respectively.

The anaesthetic technique may influence clinical outcomes, but inherent confounding and small effect sizes makes this challenging to study. We hypothesized that regional anaesthesia (RA) is associated with higher survival and fewer postoperative organ dysfunctions when compared with general anaesthesia (GA). We matched surgical procedures and type of anaesthesia using the US National Surgical Quality Improvement database, in which 264,421 received GA and 64,119 received RA. Procedures were matched according to Current Procedural Terminology (CPT) and ASA physical status classification. Our primary outcome was 30-day postoperative mortality and secondary outcomes were hospital length of stay, and postoperative organ system dysfunction. After matching, multiple regression analysis was used to examine associations between anaesthetic type and outcomes, adjusting for covariates. After matching and adjusting for covariates, type of anaesthesia did not significantly impact 30-day mortality. RA was significantly associated with increased likelihood of early discharge (HR 1.09; P< 0.001), 47% lower odds of intraoperative complications, and 24% lower odds of respiratory complications. RA was also associated with 16% lower odds of developing deep vein thrombosis and 15% lower odds of developing any one postoperative complication (OR 0.85; P < 0.001). There was no evidence of an effect of anaesthesia technique on postoperative MI, stroke, renal complications, pulmonary embolism or peripheral nerve injury. After adjusting for clinical and patient characteristic confounders, RA was associated with significantly lower odds of several postoperative complications, decreased hospital length of stay, but not mortality when compared with GA. © The Author 2016.

A retrospective analysis. To evaluate the association between early postoperative dural sac cross-sectional area (DCSA) and radicular pain. The correlation between postoperative magnetic resonance imaging (MRI) findings and postoperative neurological symptoms after lumbar decompression surgery is controversial. This study included 115 patients who underwent lumbar decompression surgery followed by MRI within 7 days postoperatively. There were 46 patients with early postoperative radicular pain, regardless of whether the pain was mild or similar to that before surgery. The intervertebral level with the smallest DCSA was identified on MRI and compared preoperatively and postoperatively. Risk factors for postoperative radicular pain were determined using univariate and multivariate analyses. Subanalysis according to absence/presence of a residual suction drain also was performed. Multivariate regression analysis showed that smaller postoperative DCSA was significantly associated with early postoperative radicular pain (per -10 mm; odds ratio, 1.26). The best cutoff value for radicular pain was early postoperative DCSA of 67.7 mm. Even with a cutoff value of <70 mm, sensitivity and specificity are 74.3% and 75.0%, respectively. Early postoperative DCSA was significantly larger before suction drain removal than after (119.7±10.1 vs. 93.9±5.4 mm). Smaller DCSA in the early postoperative period was associated with radicular pain after lumbar decompression surgery. The best cutoff value for postoperative radicular pain was 67.7 mm. Absence of a suction drain at the time of early postoperative MRI was related to smaller DCSA.

Background: Chronic rhinosinusitis has a major impact on the quality of life of patients with cystic fibrosis (CF) and may contribute to progression of chronic lung disease. Despite multiple sinus surgeries, maxillary sinus involvement is a recurrent problem. The modified endoscopic medial maxillectomy (MEMM) permits debridement in the clinic, improves mucus clearance with nasal irrigations, and increases access for topical delivery of therapeutics. However, clinical outcomes of aggressive sinus surgery with regimented postoperative medical treatment have not been systematically evaluated. Methods: CF patients completed the 22-Item Sinonasal Outcome Test questionnaires before sinus surgery (and bilateral MEMM) and at sequential postoperative visits. Objective measures included Lund-Kennedy endoscopic score and pulmonary function tests (forced expiratory volume at 1 second percent [FEV1%] predicted). Culture-directed antibiotic therapy, prednisone, and topical irrigations were initiated postoperatively. Results: Twenty-two patients (mean age, 26.5 years; 4.9 prior sinus operations) underwent MEMM and sinus surgery. Symptom scores were significantly reduced at 60 days (primary outcome, 64.7 ± 18.4 presurgery versus 27.5 ± 15.3 postsurgery; p < 0.0001) and up to a year postoperatively (27.6 ± 12.6; p < 0.0001). Endoscopic scores were also reduced after surgery (10.4 ± 1.1 presurgery versus 5.7 ± 2.4 [30 days], 5.7 ± 1.4 [60 days], 5.8 ± 1.3 [120 days], and 6.0 ± 1.1 [1 year]; p < 0.0001)]. There were no differences in FEV1% predicted up to 1 year postoperatively, but hospital admissions secondary to pulmonary exacerbations significantly decreased (2.0 ± 1.4 versus 3.2 ± 2.4, respectively; p < 0.05). Conclusion: Prospective evaluation indicates sinus surgery with MEMM is associated with marked improvement in sinus disease outcomes. Additional studies are necessary to confirm whether this treatment paradigm is associated with improved CF pulmonary disease

Intraoperative neuromonitoring (IONM) through electromyography (EMG) studies has been shown to be a safe, effective way to determine the laterality of the spinal cord and guide electrode placement during spinal cord stimulation (SCS). However, the use of IONM to predict post-operative energy requirements and midline has not been examined and offers a new avenue to streamline programming and device selection. Further, the impact of cerebrospinal fluid (CSF) thickness on intraoperative and post-operative amplitudes is understood but has not been explicitly characterized. A total of 24 patients undergoing SCS implantation for chronic pain had intraoperative EMG studies performed to determine physiologic midline. The intraoperative midline was compared to the midline determined on post-operative day 1 based on paresthesia patterns during programming. For patients who had thoracic leads placed, the amplitudes needed to induce abdominal and extremity lateralization during SCS placement were compared with the intensities needed to induce therapy at post-operative day 1. Additionally, we examined whether CSF thickness, body mass index, diabetes, drug use, and smoking correlated with intraoperative and post-operative amplitudes. Intraoperative EMG was able to predict post-operative paresthesia-based midline in 70.83% of patients. There was a statistically significant relationship between the intraoperative intensity needed to induce extremity lateralization with the post-operative intensity to induce therapy (p = 0.009) as well as the intraoperative intensity needed to stimulate abdominals with the post-operative intensity (p = 0.033). There was also a relationship seen between CSF thickness and the post-operative energy requirements in patients (p = 0.039). EMG accurately predicts post-operative energy requirements and midline in SCS patients. While 29.17% of patients did not have a match between their intraoperative and post-operative midlines, EMG testing was

Introduction: The analgesic effect of low-level laser therapy (LLLT) after mandibular third molar (MTM) extraction is controversial. The aim is to evaluate the effect of intraoral LLLT on postoperative pain after MTMs extraction. Methods: Thirty patients with bilateral symmetrical impacted MTMs underwent surgical extractions. Experimental and control sides were randomly selected to receive LLLT or placebo. Following suturing, a dental assistant applied 810 nm gallium aluminum arsenide (GaAlAs) at three points for 30 s each with a total energy of 9 J. Pain was recorded on a visual analog scale on the 7 successive days. Results: Data analyzed by IBM SPSS Statistics 23 for Windows with P ≤ 0.05 significance level. LLLT appeared to have a high significant effect on pain reduction; however, there was a mild increase in pain after the 4th day. Conclusion: Intraoral 810 nm GaAlAs is effective in reducing postoperative pain when a dose of 32.86 J/cm2 is used. PMID:29264287

Patient safety is foundational to neurosurgical care. Postprocedural "debrief" checklists have been proposed to improve patient safety, but data about their use in neurosurgery are limited. Here, we implemented an initiative to routinely perform postoperative debriefs and evaluated the impact of debriefing on operating room (OR) safety culture. A 10-question safety attitude questionnaire (SAQ) was sent to neurosurgical OR staff at a major academic medical center before and 18 months after the implementation of a postoperative debriefing initiative. Rates of debrief compliance and changes in attitudes before and after the survey were evaluated. The survey used a Likert scale and analyzed with standard statistical methods. After the debrief initiative, the rate of debriefing increased from 51% to 86% of cases for the neurosurgery service. Baseline SAQ responses found that neurosurgeons had a more favorable perception of OR safety than did anesthesiologists and nurses. After implementation of the postoperative debriefing process, perceptions of OR safety significantly improved for neurosurgeons, anesthesiologists, and nurses. Furthermore, the disparity between nurses and surgeons was no longer significant. After debrief implementation, neurosurgical OR staff had improved perceptions of patient safety compared with surgical services that did not commonly perform debriefing. Debriefing identified OR efficiency concerns in 26.9% of cases, and prevention of potential adverse events/near misses was reported in 8% of cases. Postoperative debriefing can be effectively introduced into the OR and improves the safety culture after implementation. Debriefing is an effective tool to identify OR inefficiencies and potential adverse events. Copyright © 2017 Elsevier Inc. All rights reserved.

Postoperative cognitive dysfunction (POCD) is a subtle impairment of cognitive abilities and can manifest on different neuropsychological features in the early postoperative period. It has been proved that the use of mechanical ventilation (MV) increased the development of delirium and POCD. However, the impact of variable and conventional lung protective mechanical ventilation on the incidence of POCD still remains unknown, which was the aim of this study. 162 patients scheduled to undergo elective gastrointestinal tumor resection via laparotomy in Ningbo No. 2 hospital with expected duration >2 h from June, 2013 to June, 2015 were enrolled in this study. Patients included were divided into two groups according to the scheme of lung protective MV, variable ventilation group (VV group, n=79) and conventional ventilation group (CV group, n=83) by randomization performed by random block randomization. The plasma levels of inflammatory cytokines, characteristics of the surgical procedure, incidence of delirium and POCD were collected and compared. Postoperative delirium was detected in 36 of 162 patients (22.2%) and 12 patients of these (16.5%) belonged to the VV group while 24 patients (28.9%) were in the CV group (P=0.036). POCD on the seventh postoperative day in CV group (26/83, 31.3%) was increased in comparison with the VV group (14/79, 17.7%) with significant statistical difference (P=0.045). The levels of inflammatory cytokines were all significantly higher in CV group than those in VV group on the 1st postoperative day (P<0.05). On 7th postoperative day, the levels of IL-6 and TNF-α in CV group remained much higher compared with VV group (P<0.05). Variable vs conventional lung protective MV decreased the incidence of postoperative delirium and POCD by reducing the systemic proinflammatory response.

Background Numerous studies report that bariatric surgery patients report more physical activity (PA) after surgery than before, but the quality of PA assessment has been questionable. Methods The Longitudinal Assessment of Bariatric Surgery-2 is a 10-center longitudinal study of adults undergoing bariatric surgery. Of 2458 participants, 455 were given an activity monitor, which records steps/minute, and an exercise diary before and 1 year after surgery. Mean step/day, active minutes/day, and high-cadence minutes/week were calculated for 310 participants who wore the monitor at least 10 hours/day for at least 3 days at both time points. Pre- and post-surgery PA were compared for differences using the Wilcoxon signed-rank test. Generalized Estimating Equations identified independent pre-operative predictors of post-operative PA. Results PA increased significantly (p<.0001) pre- to post-operative for all PA measures. Median values pre- and post-operative were: 7563 and 8788 steps/day; 309 and 340 active minutes/day; and 72 and 112 high-cadence minutes/week, respectively. However, depending on the PA measure, 24–29% of participants were at least 5% less active post-operative than pre-operative. Controlling for surgical procedure, sex, age and BMI, higher PA preoperative independently predicted higher PA post-operative (p<.0001, all PA measures). Less pain, not having asthma and self-report of increasing PA as a weight loss strategy pre-operative also independently predicted more high-cadence minutes/week post-operative (p<.05). Conclusion The majority of adults increase their PA level following bariatric surgery. However, most remain insufficiently active and some become less active. Increasing PA, addressing pain and treating asthma prior to surgery may have a positive impact on post-operative PA. PMID:21944951

The aim of this preliminary randomized clinical trial was to compare: (1) post-operative morbidity after application of laser or scalpel incision for flap advancement during implant surgery and bone grafting and (2) implant survival rate following flap advancement with laser or scalpel incision after 6 months of loading. Eighteen patients who were scheduled for dental implant placement and simultaneous bone grafting were randomly assigned to test or control groups. Diode laser (810 nm, 2 W, pulse interval 200 μs; pulse length 100 μs, 400-μm initiated fiber tip), or scalpel (control) was used to sever the periosteum to create a tension-free flap. Visual analogue scale (VAS) pain score, rate of nonsteroid anti-inflammatory drug (NSAID) consumption, intensity of swelling, and ecchymosis were measured for the six postsurgical days. Six months after loading, implant survival was assessed. VAS pain score (during the first four postoperative days), rate of NSAID consumption (during the first three postoperative days), and intensity of swelling (during the first five postoperative days) were significantly lower in the test group compared to the control group (All P values < 0.05). One patient in the control group experienced ecchymosis. All implants were successful in function. Application of laser for performing periosteal releasing incision reduced the incidence and severity of postoperative morbidity of the patients undergone implant surgery in conjunction with bone augmentation procedure. We did not find any detrimental effect of laser incision on the implant survival within 6 months of loading.

Despite the widespread use of minimally invasive radical prostatectomy (MIRP), there remain concerns regarding its safety in patients with a history of prior abdominopelvic or inguinal surgery. A prospective database of 1165 MIRP procedures performed by a single surgeon at a high-volume tertiary care center from 2001 to 2013 was analyzed. After an initial period of transperitoneal MIRP (TP), an extraperitoneal (EP) approach was used preferentially beginning in 2005 (for both laparoscopic and robotic cases), and robotics were used preferentially beginning in 2010. Overall perioperative complications, major complications (Clavien-Dindo III or IV), and abdominal complications (e.g., ileus, bowel/organ injury, or vascular injury) were compared for patients with and without a prior surgical history. Uni- and multivariate logistic regression were used to control the impact of robotics, approach, operative time, estimated blood loss, case number, prostate weight, and primary Gleason on complications. Three hundred patients undergoing MIRP had prior abdominopelvic or inguinal surgery (25.8%). Of these, 102 (34%) underwent TP and 198 (66%) EP MIRP. Robotics was used in 286 cases (24.6%) and pure laparoscopy in 879 (75.4%). Complications occurred in 111 patients (9.5%) from the total cohort, with major complications in 32 (2.75%) and abdominal complications in 19 (1.63%). Prior surgery was not associated with overall, major, or abdominal complications. Of the controlling factors, only increasing operative time was associated with postoperative abdominal complications (most of which were ileus) on multivariate analysis. In this large single-surgeon series where both EP and TP approaches to MIRP are utilized, prior abdominopelvic or inguinal surgery was not associated with an increased risk of perioperative complications.

Lobectomy is preferred in thyroid cancer to decrease surgical complications and avoid lifelong thyroid-hormone replacement. However, postoperative hypothyroidism, requiring thyroid-hormone replacement, may occur. We aimed to identify the incidence and risk factors of postoperative hypothyroidism to develop a surveillance strategy after lobectomy for papillary thyroid microcarcinoma (PTMC). This historical cohort study involved 335 patients with PTMC treated by lobectomy. Postoperative thyroid functions were measured regularly, and patients were prescribed levothyroxine according to specific criteria. Patients not satisfying hormone-replacement criteria were closely followed up. Postoperative hypothyroidism occurred in 215 patients (64.2%) including 5 (1.5%) with overt hypothyroidism and 210 (62.7%) with subclinical hypothyroidism. Forty patients (11.9%) were required thyroid hormone replacement. One hundred nineteen patients (33.5%) experienced temporary hypothyroidism and spontaneously recovered to euthyroid state. High preoperative thyroid-stimulating hormone (TSH) was the most important factor predicting postoperative hypothyroidism and failure of recover from hypothyroidism (odds ratio [OR], 2.82 and 1.77; 95% confidence interval [CI], 2.07 to 3.95 and 1.22 to 2.63; P < 0.001 and 0.002, respectively). Of the 215 patients eventually developing postoperative hypothyroidism, 70 (32.6%) developed hypothyroidism after the first postoperative year. Postoperative 1-year TSH levels were able to differentiate patients developing late hypothyroidism or euthyroidism (OR, 2.29; 95% CI, 1.68 to 3.26; P < 0.001). Preoperative and postoperative TSH levels might be predictive for patients who develop postlobectomy hypothyroidism and identify those requiring long-term surveillance for hypothyroidism. Additionally, mild postoperative hypothyroidism cases should be followed up without immediate levothyroxine replacement with the expectation of spontaneous recovery. Copyright �

Diabetes type 2 (DM) or impaired glucose tolerance (IGT) are linked with a 3-fold increased risk of renal failure after heart valve surgery. The increase of proinflammatory cytokines is detected in patients with DM or IGT, moreover cardiac surgery promotes the proinflammatory response, which may be responsible for the development of postoperative kidney failure. To assess the impact of perioperative pro- and antiinflammatory reaction after heart valve surgery and other clinical parameters on the risk of postoperative acute kidney injury in patients with DM or IGT. Thirty patients with DM or IGT, without fibrate or statin treatment, with a mean LDL-cholesterol below 129 mg/dL, ejection fraction > 45%, in NYHA class II and III, referred for surgery due to acquired heart valve disease entered the study. Patients with acute or chronic inflammatory conditions, coronary artery disease or creatinine clearance below 50 mL/min were excluded. Serum creatinine, glycosylated hemoglobin, LDL-cholesterol and interleukin-10 as well as TNF-alpha were assessed before surgery. Interleukin-10 and TNF-alpha were also measured 4 hours after weaning from cardiopulmonary bypass. Moreover, serum creatinine and hemoglobin were measured 18 +/- 2 hours after surgery. The relationship between postoperative creatinine clearance, its postoperative change and other parameters was assessed. These parameters included: age, weight and body mass index, pre- and postoperative serum level of TNF-alpha and interleukin-10, preoperative concentration of LDL-cholesterol and glycosylated hemoglobin, duration of cardiopulmonary bypass and postoperative hemoglobin. The significant postoperative decrease of creatinine clearance was noted in the study group. Eight (27%) patients developed postoperative kidney failure, of them 2 (6.5%) patients required hemodialysis. The level of TNF-alpha and interleukin-10 increased significantly postoperatively.

The aim of this study was to determine the types, incidence, and risk factors for early postoperative pulmonary complications in heart transplant recipients. We retrospectively collected data from the records of consecutive heart transplantations from January 2003 to December 2013. A total of 83 patients underwent heart transplantation. The data collected for each case were demographic features, duration of mechanical ventilation, respiratory problems that developed during the intensive care unit (ICU) stay, and early postoperative mortality (<30 d). Of the 72 patients considered, 52 (72.2%) were male. The overall mean age at the time of transplantation was 32.1 ± 16.6 years. Twenty-five patients (34.7%) developed early postoperative respiratory complications. The most frequent problem was pleural effusion (n = 19; 26.4%), followed by atelectasis (n = 6; 8.3%), acute respiratory distress syndrome (n = 5; 6.9%), pulmonary edema (n = 4; 5.6%), and pneumonia (n = 3; 4.2%). Postoperative duration of mechanical ventilation (44.2 ± 59.2 h vs 123.8 ± 190.8 h; P = .005) and the length of postoperative ICU stay (10.1 ± 5.8 h vs 19.8 ± 28.9 h; P = .03) were longer among patients who had respiratory problems. Postoperative length of stay in the hospital (22.3 ± 12.5 d vs 30.3 ± 38.3 d; P = .75) was similar in the 2 groups. The overall mortality rate was 12.5% (n = 9). The patients who had respiratory problems did not show higher mortality than those who did not have respiratory problems (16.0% vs 10.6%; P = .71). Respiratory complications were relatively common in our cohort of heart transplant recipients. However, these complications were mostly self-limiting and did not result in worse mortality.

After hepatic resection, delayed flatus and impaired bowel movement often cause problematic postoperative ileus. Kampo medicine, Dai-kenchu-to (DKT), is reported to have a various beneficial effects on bowel systems. The aim of this study was to prospectively evaluate effects of DKT after hepatic resection. Thirty-two patients who underwent hepatic resection between July 2007 and August 2008 in Tokushima University Hospital were prospectively divided into DKT group (n=16) and control group (n=16). In DKT group, 2.5 g of DKT was administered orally three times a day from postoperative day (POD) 1. Blood was examined on POD 1, 3, 5 and 7. Postoperative first flatus, bowel movement and full recovery of oral intake, hospital stays and complications were checked. In DKT group, levels of c-reactive protein and beta-(1-3)-D-glucan on POD 3 were significantly decreased (p<0.05). Moreover, postoperative periods for the first flatus, bowel movement and the full recovery of oral intake were significantly shortened in DKT group (p<0.05). DKT suppressed inflammatory reaction, stimulated bowel movement and improved oral intake after hepatic resection, which may decrease serious morbidity after hepatic resection.

Postoperative Delirium in the Geriatric Patient

PubMed Central

Schenning, Katie J.; Deiner, Stacie G.

SYNOPSIS Postoperative delirium, a common complication in older surgical patients, is independently associated with increased morbidity and mortality. Patients over the age of 65 years receive greater than 1/3 of the over 40 million anesthetics delivered yearly in the United States. This number is expected to increase with the aging of the population. Thus, it is increasingly important that perioperative clinicians who care for geriatric patients have an understanding of the complex syndrome of postoperative delirium. PMID:26315635

Cosmetic tourism is defined as patient mobility across borders, typically constituted by patients seeking cosmetic surgery at lower costs abroad. The most common procedures are abdominoplasty, fat grafting and breast augmentation. Very little is known about the complication rates after cosmetic tourism, and there is a paucity of evidence in all aspects of cosmetic tourism. In this review, we focus on post-operative complications i.e. post-operative infections, in particular with rare microorganisms such as mycobacteria.

The objective of this study was to investigate the effect of preoperative diastolic dysfunction on postoperative mortality and morbidity after cardiovascular surgery. We systematically searched for articles that assessed the prognostic role of diastolic dysfunction on cardiovascular surgery in PubMed, Cochrane Library, Web of Science, Embase, and Scopus until February 2016. Twelve studies (n = 8224) met our inclusion criteria. Because of the scarcity of outcome events, fixed-effects meta-analysis was performed via the Mantel-Haenszel method. Preoperative diagnosis of diastolic dysfunction was associated with greater postoperative mortality (odds ratio [OR], 2.41; 95% confidence interval [CI], 1.54-3.71; P < .0001), major adverse cardiac events (OR, 2.07; 95% CI, 1.55-2.78; P ≤ .0001), and prolonged mechanical ventilation (OR, 2.08; 95% CI, 1.04-4.16; P = .04) compared with patients without diastolic dysfunction among patients who underwent cardiovascular surgery. The odds of postoperative myocardial infarction (OR, 1.29; 95% CI, 0.82-2.05; P = .28) and atrial fibrillation (OR, 2.67; 95% CI, 0.49-14.43; P = .25) did not significantly differ between the 2 groups. Severity of preoperative diastolic dysfunction was associated with increased postoperative mortality (OR, 21.22; 95% CI, 3.74-120.33; P = .0006) for Grade 3 diastolic dysfunction compared with patients with normal diastolic function. Inclusion of left ventricular ejection fraction (LVEF) <40% accompanying diastolic dysfunction did not further impact postoperative mortality (P = .27; I(2) = 18%) compared with patients with normal LVEF and diastolic dysfunction. Presence of preoperative diastolic dysfunction was associated with greater postoperative mortality and major adverse cardiac events, regardless of LVEF. Mortality was significantly greater in grade III diastolic dysfunction. Copyright © 2016 The American Association for Thoracic Surgery. Published by Elsevier Inc. All rights

Delirium after surgery is a common condition that leads to poor outcomes. Few studies have examined the effect of postoperative delirium on outcomes after cardiac surgery. To assess the relationship between delirium after cardiac surgery and the following outcomes: length of stay after surgery, prevalence of falls, discharge to a nursing facility, discharge to home with home health services, and use of inpatient physical therapy. Electronic medical records of 656 cardiac surgery patients were reviewed retrospectively. Postoperative delirium occurred in 161 patients (24.5%). Patients with postoperative delirium had significantly longer stays (P < .001) and greater prevalence of falls (P < .001) than did patients without delirium. Patients with delirium also had a significantly greater likelihood for discharge to a nursing facility (P < .001) and need for home health services if discharged to home (P < .001) and a significantly higher need for inpatient physical therapy (P < .001). Compared with patients without postoperative delirium, patients who had this complication were more likely to have received zolpidem and benzodiazepines postoperatively and to have a history of arrhythmias, renal disease, and congestive heart failure. Patients who have delirium after cardiac surgery have poorer outcomes than do similar patients without this complication. Development and implementation of an extensive care plan to address postoperative delirium is necessary for cardiac surgery patients who are at risk for or have delirium after the surgery. ©2015 American Association of Critical-Care Nurses.

We herein report a case of abdominal actinomycosis in a 12-year-old girl in whom an omental primary tumor was suspected before surgery. The patient began to experience intermittent lower left abdominal pain. Abdominal computed tomography (CT) scans were inconclusive at this time, but 6 months later, CT and magnetic resonance imaging (MRI) examinations showed a 7-cm, tumor-like lesion in the left abdominal cavity; malignancy could not be ruled out. The tumor, which originated in the omentum and adhered strongly to the left abdominal wall, was resected along with approximately 90 % of the omentum, the peritoneum in contact with the mass, and the posterior layer of the rectus abdominal sheath, under suspicion of a malignant tumor. However, omental actinomycosis was the final pathological diagnosis. The patient's antibiotic treatment was changed to a penicillin-series oral antibiotic to prevent recurrence of the actinomycosis. The patient was discharged from our hospital 16 days after the first surgery, but she developed three episodes of ileus; the first two required surgery. The patient has had no further recurrences of actinomycosis or postoperative ileus 20 months after discharge.

evidence using GRADE (Grading of Recommendations Assessment, Development and Evaluation). We identified seven studies that met inclusion criteria for this review. Three were recorded as completed (or terminated) but no results were published. Of the remaining four studies (299 participants): two investigated liposomal bupivacaine transversus abdominis plane (TAP) block, one liposomal bupivacaine dorsal penile nerve block, and one ankle block. The study investigating liposomal bupivacaine ankle block was a Phase II dose-escalating/de-escalating trial presenting pooled data that we could not use in our analysis.The studies did not report our primary outcome, cumulative pain score between 0 and 72 hours, and secondary outcomes, mean pain score at 12, 24, 48, 72, or 96 hours. One study reported no difference in mean pain score during the first, second, and third postoperative 24-hour periods in participants receiving liposomal bupivacaine TAP block compared to no TAP block. Two studies, both in people undergoing laparoscopic surgery under TAP block, investigated cumulative postoperative opioid dose, reported opposing findings. One found a lower cumulative opioid consumption between 0 and 72 hours compared to bupivacaine hydrochloride TAP block and one found no difference during the first, second, and third postoperative 24-hour periods compared to no TAP block. No studies reported time to first postoperative opioid or percentage not requiring opioids over the initial 72 hours. No studies reported a health economic analysis or patient-reported outcome measures (outside of pain). The review authors sought data regarding adverse events but none were available, however there were no withdrawals reported to be due to adverse events.Using GRADE, we considered the quality of evidence to be very low with any estimate of effect very uncertain and further research very likely to have an important impact on our confidence in the estimate of effect. All studies were at high risk of bias

The Post-operative Morbidity Index (PMI) is a quantitative utility measure of a complication burden created by severity weighting. The Fistula Risk Score (FRS) is a validated model that predicts whether a patient will develop a post-operative pancreatic fistula (POPF). These novel tools might provide further discrimination of the ISGPF grading system. From 2001 to 2012, 1021 pancreaticoduodenectomies were performed at four institutions. POPFs were categorized by ISGPF standards. PMI scores were calculated based on the Modified Accordion Severity Grading System. FRS scores were assigned according to the relative influence of four recognized factors for developing a clinically relevant POPF (CR-POPF). In total, 231 patients (22.6%) developed a POPF, of which 54.1% were CR-POPFs. The PMI differed significantly between the ISGPF grades and patients with no or non-fistulous complications (P < 0.001). 64.9% of POPFs and 84.0% of CR-POPFs contributed the highest Accordion grade to the PMI. Overall, the FRS correlated well with PMI (R(2) = 0.81, P < 0.001). These data quantitatively reinforce the ISGPF grades that were developed qualitatively around the concept of clinical severity. CR-POPFs usually reflect the patient's highest Accordion score whereas biochemical POPFs are often superseded. The correlation between FRS and PMI indicates that risk factors for a fistula contribute to overall pancreaticoduodenectomy morbidity. © 2013 International Hepato-Pancreato-Biliary Association.

Background Given their ability to process highly dimensional datasets with hundreds of variables, machine learning algorithms may offer one solution to the vexing challenge of predicting postoperative pain. Methods Here, we report on the application of machine learning algorithms to predict postoperative pain outcomes in a retrospective cohort of 8071 surgical patients using 796 clinical variables. Five algorithms were compared in terms of their ability to forecast moderate to severe postoperative pain: Least Absolute Shrinkage and Selection Operator (LASSO), gradient-boosted decision tree, support vector machine, neural network, and k-nearest neighbor, with logistic regression included for baseline comparison. Results In forecasting moderate to severe postoperative pain for postoperative day (POD) 1, the LASSO algorithm, using all 796 variables, had the highest accuracy with an area under the receiver-operating curve (ROC) of 0.704. Next, the gradient-boosted decision tree had an ROC of 0.665 and the k-nearest neighbor algorithm had an ROC of 0.643. For POD 3, the LASSO algorithm, using all variables, again had the highest accuracy, with an ROC of 0.727. Logistic regression had a lower ROC of 0.5 for predicting pain outcomes on POD 1 and 3. Conclusions Machine learning algorithms, when combined with complex and heterogeneous data from electronic medical record systems, can forecast acute postoperative pain outcomes with accuracies similar to methods that rely only on variables specifically collected for pain outcome prediction.

Our purposes were to determine the influence of psychological profile on hemodynamic changes in patients who undergo surgical removal of the third molars under intravenous sedation and to evaluate the effect on patients' anxiety and postoperative recovery. We performed a prospective study of 100 patients (American Society of Anesthesiologists classes I and II; aged ≥18 years) seen in the CIMIVClinic (Department of Oral Surgery, Casa de Salud University Hospital, Valencia, Spain) who underwent extractions of all third molars under intravenous sedation. All patients were administered the Symptom Checklist 90 Revised (SCL-90-R). The following parameters were monitored at different times during the surgical interventions: systolic blood pressure, diastolic blood pressure, oxygen saturation, and heart rate. Position and depth of impaction of the tooth (Pell and Gregory classification and Winter classification), surgery duration, and surgical technique also were recorded. Finally, the degree of pain experienced the week after the surgical intervention was measured using a visual analog scale. Patients' anxiety levels preoperatively were significantly higher in patients with psychological distress (P = .023). Postoperative pain significantly decreased from the first day to the seventh day in healthy patients but not in patients with altered psychological conditions (P < .05). Nevertheless, the hemodynamic changes were not correlated with the psychological impairment. Intravenous sedation enables the control of hemodynamic changes in all patients independently of their psychological profile. Patients with psychological distress present with higher levels of dental anxiety and postoperative pain. Future studies are needed to further clarify this interaction.

Grade C postoperative pancreatic fistula refers to those postoperative pancreatic fistula that require reoperation or lead to single or multiple organ failure and/or mortality attributable to the pancreatic fistula. This new definition and grading system of postoperative pancreatic fistula should lead to a more universally consistent evaluation of operative outcomes after pancreatic operation and will allow for a better comparison of techniques used to mitigate the rate and clinical impact of a pancreatic fistula. Use of this updated classification will also allow for more precise comparisons of surgical quality between surgeons and units who perform pancreatic surgery. Copyright © 2016 Elsevier Inc.

Copeptin is a stable surrogate marker of vasopressin release; the peptides are stoichiometrically secreted from the neurohypophysis due to elevated plasma osmolality or nonosmotic stress. We hypothesized that following stress from pituitary surgery, patients with neurohypophyseal damage and eventual diabetes insipidus (DI) would not exhibit the expected pronounced copeptin elevation. The objective was to evaluate copeptin's accuracy to predict DI following pituitary surgery. This was a prospective multicenter observational cohort study. Three Swiss or Canadian referral centers were used. Consecutive pituitary surgery patients were included. Copeptin was measured postoperatively daily until discharge. Logistic regression models and diagnostic performance measures were calculated to assess relationships of postoperative copeptin levels and DI. Of 205 patients, 50 (24.4%) developed postoperative DI. Post-surgically, median [25th-75th percentile] copeptin levels were significantly lower in patients developing DI vs those not showing this complication: 2.9 [1.9-7.9] pmol/L vs 10.8 [5.2-30.4] pmol/L; P < .001. Logistic regression analysis revealed strong association between postoperative copeptin concentrations and DI even after considering known predisposing factors for DI: adjusted odds ratio (95% confidence interval) 1.41 (1.16-1.73). DI was seen in 22/27 patients with copeptin <2.5 pmol/L (positive predictive value, 81%; specificity, 97%), but only 1/40 with copeptin >30 pmol/L (negative predictive value, 95%; sensitivity, 94%) on postoperative day 1. Lack of standardized DI diagnostic criteria; postoperative blood samples for copeptin obtained during everyday care vs at fixed time points. In patients undergoing pituitary procedures, low copeptin levels despite surgical stress reflect postoperative DI, whereas high levels virtually exclude it. Copeptin therefore may become a novel tool for early goal-directed management of postoperative DI.

Enduring prevention and transient reduction of postoperative pain by intrathecal resolvin D1

Postoperative pain slows surgical recovery, impacting the return of normal function for weeks, months, or longer. Here we report the antihyperalgesic actions of a new compound, resolvin D1 (RvD1), known to reduce inflammation and to suppress pain after peripheral nerve injury, on the acute pain occurring after paw incision and the prolonged pain after skin-muscle retraction. Injection of RvD1 (20–40 ng) into the L5–L6 intrathecal space 30 minutes before surgery reduces the postincisional primary mechanical hypersensitivity, lowering the peak change by approximately 70% (with 40 ng) and reducing the area under the curve (AUC) for the entire 10-day postincisional course by approximately 60%. Intrathecal injection of RvD1 on postoperative day (POD) 1 reduces the hyperalgesia to the same level as that from preoperative injection within a few hours, an effect that persists for the remaining PODs. Tactile allodynia and hyperalgesia following the skin/muscle incision retraction procedure, measured at the maximum values 12 to 14 days, is totally prevented by intrathecal RvD1 (40 ng) given at POD 2. However, delaying the injection until POD 9 or POD 17 results in RvD1 causing only transient and incomplete reversal of hyperalgesia, lasting for <1 day. These findings demonstrate the potent, effective reduction of postoperative pain by intrathecal RvD1 given before or shortly after surgery. The much more limited effect of this compound on retraction-induced pain, when given 1 to 2 weeks later, suggests that the receptors or pathways for resolvins are more important in the early than the later stages of postoperative pain.

Postoperative delirium is a serious and common complication in older adults following total joint arthroplasties (TJA). It is associated with increased risk of postoperative complications, mortality, length of hospital stay and postdischarge institutionalisation. Thus, it has a negative impact on the health-related quality of life of the patient and poses a large economic burden. This study aims to characterise the incidence of postoperative delirium following TJA in the South East Asian population and investigate any risk factors or associated outcomes. This is a single-centre prospective observational study recruiting patients between 65 and 90 years old undergoing elective total knee arthroplasty or total hip arthroplasty. Exclusion criteria included patients with clinically diagnosed dementia. Preoperative and intraoperative data will be obtained prospectively. The primary outcome will be the presence of postoperative delirium assessed using the Confusion Assessment Method on postoperative days 1, 2 and 3 and day of discharge. Other secondary outcomes assessed postoperatively will include hospital outcomes, pain at rest, knee and hip function, health-related quality of life and Postoperative Morbidity Survey-defined morbidity. Data will be analysed to calculate the incidence of postoperative delirium. Potential risk factors and any associated outcomes of postoperative delirium will also be determined. This study has been approved by the Singapore General Hospital Institutional Review Board (SGH IRB) (CIRB Ref: 2017/2467) and is registered on the ClinicalTrials.gov registry (Identified: NCT03260218). An informed consent form will be signed by all participants before recruitment and translators will be made available to non-English-speaking participants. The results of this study will be presented at international conferences and submitted to a peer-reviewed journal. The data collected will also be made available in a public data repository.

Use of postoperative steroids to reduce pain and inflammation.

PubMed

Fleischli, J W; Adams, W R

1999-01-01

Postoperative injection of a steroid is used by many podiatric surgeons to reduce pain and inflammation after foot surgery. The authors present a review of the literature on postoperative steroid use from many medical specialties as well as a review of wound and bone healing. The literature indicates that using a steroid is a safe and effective means to reduce postoperative pain and edema. Studies have shown steroids to delay healing, inhibit collagen synthesis, and increase the risk of postoperative infection. No author reported a delay in wound or bone healing or increased infection rate in patients in which a steroid was used. Although there is literature to support this practice, many questions remain and further investigation is needed.

Epilepsy is one of the most common manifestations in gliomas and has a severe effect on the life expectancy and quality of life of patients. The aim of our study was to assess the potential connections between clinicopathological factors and postoperative seizure. We retrospectively investigated a group of 147 Chinese high-grade glioma (HGG) patients with preoperative seizure to examine the correlation between postoperative seizure and clinicopathological factors and prognosis. Univariate analyses and multivariate logistic regression analyses were performed to identify factors associated with postoperative seizures. Survival function curves were calculated using the Kaplan-Meier method. 53 patients (36%) were completely seizure-free (Engel class I), and 94 (64%) experienced a postoperative seizure (Engel classes II, III, and IV). A Chi-squared analysis showed that anaplastic oligodendroglioma/anaplastic oligoastrocytoma (AO/AOA) (P=0.05), epidermal growth factor receptor (EGFR) expression (P=0.0004), O(6)-methylguanine DNA methyltransferase (MGMT) expression (P=0.011), and phosphatase and tensin homolog (PTEN) expression (P=0.045) were all significantly different. A logistic regression analysis showed that MGMT expression (P=0.05), EGFR expression (P=0.001), and AO/AOA (P=0.038) are independent factors of postoperative seizure. Patients with lower MGMT and EGFR expression and AO/AOA showed more frequent instances of postoperative seizure. Postoperative seizure showed no statistical significance on overall survival (OS) and progression-free survival (PFS). Our study identified clinicopathological factors related to postoperative seizure in HGGs and found two predictive biomarkers of postoperative seizure: MGMT and EGFR. These findings provided insight treatment strategies aimed at prolonging survival and improving quality of life. Copyright © 2016 British Epilepsy Association. Published by Elsevier Ltd.

Poorly controlled postoperative pain: prevalence, consequences, and prevention

PubMed Central

Gan, Tong J

2017-01-01

This review provides an overview of the clinical issue of poorly controlled postoperative pain and therapeutic approaches that may help to address this common unresolved health-care challenge. Postoperative pain is not adequately managed in greater than 80% of patients in the US, although rates vary depending on such factors as type of surgery performed, analgesic/anesthetic intervention used, and time elapsed after surgery. Poorly controlled acute postoperative pain is associated with increased morbidity, functional and quality-of-life impairment, delayed recovery time, prolonged duration of opioid use, and higher health-care costs. In addition, the presence and intensity of acute pain during or after surgery is predictive of the development of chronic pain. More effective analgesic/anesthetic measures in the perioperative period are needed to prevent the progression to persistent pain. Although clinical findings are inconsistent, some studies of local anesthetics and nonopioid analgesics have suggested potential benefits as preventive interventions. Conventional opioids remain the standard of care for the management of acute postoperative pain; however, the risk of opioid-related adverse events can limit optimal dosing for analgesia, leading to poorly controlled acute postoperative pain. Several new opioids have been developed that modulate μ-receptor activity by selectively engaging intracellular pathways associated with analgesia and not those associated with adverse events, creating a wider therapeutic window than unselective conventional opioids. In clinical studies, oliceridine (TRV130), a novel μ-receptor G-protein pathway-selective modulator, produced rapid postoperative analgesia with reduced prevalence of adverse events versus morphine.

Pre-operative autologous blood donation is used to reduce the need of allogeneic blood in patients undergoing coronary bypass surgery operations, but it is not clear what impact the blood donation has on the post-operative course of these patients. We studied the post-operative course of 210 patients who pre-donated autologous blood before their coronary bypass operation (donors) and of 67 patients who were eligible to pre-donate but did not (controls). The clinical variables and the technical operative parameters of the patients in the two groups were similar. There was no significant difference between the duration of assisted ventilation post-operatively (756 +/- 197 vs. 802 +/- 395 min; P=0.54) or length of stay in the intensive care unit (1.8 +/- 1.1 vs. 1.7 +/- 0.9 days; P=0.52) of the two groups. The number of autologous units of packed red cells and of fresh frozen plasma (FFP) received by the donors was significantly higher than the number of units of allogeneic packed red cells (1.5 +/- 0.9 vs. 0.3 +/- 0.9; P=0.001) and the units of homologous FFP received by the controls (2.3 +/- 0.8 vs. 0.6 +/- 1; P=0.001). We found no evidence that autologous blood donation exerted a negative influence on the post-operative course of patients undergoing coronary bypass surgery. Patients who pre-donated blood received no allogeneic blood products, but the number of autologous blood products received by donors was higher than the number of blood products received by patients who did not pre-donate.

Flurbiprofen axetil is an injectable non-selective cyclooxygenase inhibitor that has a high affinity for inflammatory tissues to achieve targeted drug therapy and prolonged duration of action. This meta-analysis examined the use of preoperative flurbiprofen axetil and its impact on postoperative analgesia. An electronic literature search of the Library of PubMed, Cochrane CENTRAL, and EMBASE databases was conducted in Feb 2016. Searches were limited to randomized controlled trials. The primary outcome was pain scores. The secondary outcomes included cumulative postoperative opioid consumption and opioid-related adverse effects. A total of nine RCT studies involving 457 patients were included in this study. Compared to patients without perioperative flurbiprofen axetil, patients treated with preoperative flurbiprofen axetil had lower pain scores at 2 h (SMD -1.00; 95% CI -1.57 to -0.43, P = 0.0006), 6 h (SMD -1.22; 95% CI -2.01 to -0.43; P = 0.002), 12 h (SMD -1.19; 95% CI -2.10 to -0.28; P = 0.01), and 24 h (SMD -0.79; 95% CI -1.31 to -0.27; P = 0.003) following surgery. Preoperative flurbiprofen axetil had no significant effect on postoperative opioid consumption (SMD -13.11; 95% CI -34.56 to 8.33; P = 0.23). There was no significant difference between the groups with regard to adverse effects. Compared to patients with postoperative flurbiprofen axetil, however, preoperative flurbiprofen axetil resulted in decreased pain score only at 2 h after operation. Preoperative use of flurbiprofen axetil will result in significantly lower postoperative pain scores, but no difference in nausea, vomiting, and opioid consumption compared to those who did not receive flurbiprofen axetil. However, more homogeneous and well-designed clinical studies are necessary to determine whether preoperative flurbiprofen axetil administration has

The aim of this comparative, prospective, randomized, controlled study was to evaluate two different regimens of analgesics: a preoperative intravenous dose of either Tramadol or Ketorolac given 10 min prior to surgery to assess their impact on clinical recovery after third molar surgery. Forty patients requiring surgical extraction of unilateral impacted mandibular third molars similar in position were enrolled in the study. Patients were randomly divided into two groups based on permuting the numbers. Patients in Group 1 and Group 2 were administered either Tramadol 50 mg or Ketorolac 30 mg, intravenously, 10 min prior to surgery. The difference in postoperative pain was assessed by four primary points: pain intensity as measured by a 10 mm visual analogue scale hourly for 12 h, median time to rescue analgesics, number of analgesics consumed and patient's overall 5-point global assessment scale. Throughout the 12 h investigation period, patients treated with Ketorolac reported significantly lower pain intensity scores, significantly longer time to rescue analgesics (Acetaminophen 500 mg) and less intake of postoperative analgesics. In Group 2, 40% of the patient had good overall assessment as compared to Group 1 where only 25% of patients had good overall assessment. The current study shows that pre-emptive use of Inj. Ketorolac 30 mg intravenously can reduce the severity of the postoperative sequelae of asymptomatic impacted mandibular third molar surgery.

Anesthesia and perioperative stress: consequences on neural networks and postoperative behaviors.

PubMed

Borsook, David; George, Edward; Kussman, Barry; Becerra, Lino

2010-12-01

Anesthesia is a state of drug-induced unconsciousness with suppression of sensory perception, and consists of both hypnotic and analgesic components. The anesthesiologist monitors the clinical response to noxious stimuli and adjusts drug dosage(s) to achieve an adequate depth of anesthesia, with the aim of reducing operative stress. Acute stress in the perioperative period has four major contributors: anxiety, pain, the surgical stress response, and the potential neurotoxicity of anesthetic agents. Any or all of these may act deleteriously on multiple systems in the brain and have known significant effects on brain regions such as the hippocampus and the hypothalamic-pituitary-adrenal axis. Perioperative stress on the nervous system and the resultant central nervous system (CNS) changes are likely to be causative for altered behaviors that are seen postoperatively, including chronic pain, posttraumatic stress disorder, and learning difficulties. Improving the ability of the anesthesiologist to control all four components of acute perioperative stress could potentially reduce the negative impact of surgery on the brain. Currently, there is no objective measurement for any of these stressors. The development and application of objective measures for perioperative stressors is the first step towards controlling these risk factors and eliminating or reducing their serious postoperative consequences. In this paper we review known and likely effects of perioperative stressors on brain systems and how they may play a significant role in altered postoperative behaviors. We discuss the role of current (and developing) measures of brain function and their potential for monitoring perioperative stress, with an emphasis on functional neuroimaging.

Purpose: To evaluate the impact of postoperative radiation therapy on the clinical course of patients with carcinoma ex pleomorphic adenoma of the parotid gland. Methods and Materials: Between 1960 and 2004, 63 patients were treated with definitive surgery for carcinoma ex pleomorphic adenoma of the parotid gland. Forty patients (63%) received postoperative radiation therapy to a median dose of 60 Gy (range, 45-71 Gy). Adenocarcinoma (29 patients), salivary duct carcinoma (16 patients), and adenoid cystic carcinoma (9 patients) were the most common malignant subtypes. Pathologic T -stage was: 16% T1, 33% T2, 32% T3, and 19% T4. Twenty-one patients (33%)more » had microscopically positive margins and 39 (62%) had perineural invasion. Median follow-up was 50 months (range, 2-96 months). Results: The use of postoperative therapy significantly improved 5-year local control from 49% to 75% (p = 0.005) and was associated with an improvement in survival among patients without evidence of cervical lymph node metastasis (p = 0.01). A Cox proportional hazard model identified pathologic involvement of cervical lymph nodes as an independent predictor of overall survival. Overall survival was 16% for patients with pathologic N-positive disease compared with 67% for those whose lymph node status was negative or unknown (p = 0.001). Conclusion: Surgery followed by postoperative radiation should be considered the standard of care for patients with carcinoma ex pleomorphic adenoma.« less

Postoperative Delirium in the Geriatric Patient.

Postoperative delirium, a common complication in older surgical patients, is independently associated with increased morbidity and mortality. Patients older than 65 years receive greater than one-third of the more than 40 million anesthetics delivered yearly in the United States. This number is expected to increase with the aging of the population. Thus, it is increasingly important that perioperative clinicians who care for geriatric patients have an understanding of the complex syndrome of postoperative delirium.

Postoperative pneumonia is a common complication of surgery, and is associated with marked morbidity and mortality. Despite advances in surgical and anesthetic technique, it persists as a frequent postoperative complication. Many studies have aimed to assess its burden, as well as associated risk factors. However, this complication varies among the different surgical specialties, and there is a paucity of reports that comprehensively evaluate this complication. Therefore, the purpose of this study was to review the epidemiology and risk factors of postoperative pneumonia in the setting of: 1) general surgery; 2) cardiothoracic surgery; 3) orthopedic and spine surgery; and 4) head and neck surgery.

We hypothesised, that the inclusion of the ilium for multilevel lumbosacral fusions reduces the incidence of postoperative sacroiliac joint (SIJ) pain. The primary objective of this study was to compare the frequency of postoperative SIJ pain in patients undergoing multilevel stabilization with and without sacropelvic fixation for multilevel degenerative spine disease. In addition, we aimed at identifying factors that may predict the worsening or new onset of postoperative SIJ pain. A total of 63 patients with multisegmental fusion surgery with a minimum follow up of 12 months were evaluated. 34 patients received sacral fixation (SF group) and 29 patients received an additional sacropelvic fixation device (SPF group). Primary outcome parameters were changes in SIJ pain between the groups and the influence of pelvic parameters, the patient́s age, the patient́s body mass index (BMI) and the length of the stabilization on the SIJ pain. Between the two surgical groups there were no differences concerning age (p=0.3), BMI (p=0.56), length of follow up (p=0.96), length of the construct (p=0.56). In total 31.7% of the patients had a worsening/new onset of SIJ pain after surgery. An additional fixation of the SIJ with iliac screws or iliosacral plate did not have an influence on the SIJ pain (p=0.67). Likewise, pelvic parameters were not predictive for the outcome of the SIJ pain. Only an increased preoperative BMI correlated with a higher chance of a new onset of SIJ pain (p=0.037). In our retrospective study there was no influence of a sacropelvic fixation techniques on the SIJ pain in patients with multilevel degenerative spine disease after multilevel stabilization surgeries. The patients' BMI is the only preoperative factor that correlated with a higher incidence to develop postoperative SIJ pain, independently of the implantation of a sacropelvic fixation device.

The effectiveness of cryotherapy on joint arthroplasty recovery remains controversial. This systematic review was conducted to assess the effectiveness of cryotherapy in patients after joint arthroplasty. Comprehensive literature searches of several databases including Cochrane Library (2013), MEDLINE (1950-2013), and Embase (1980-2013) were performed. We sought randomised controlled trials that compared the experimental group received any form of cryotherapy with any control group after joint arthroplasty. The main outcomes were postoperative blood loss, adverse events, and pain. Analyses were performed with Revman 5.0. Results were shown as mean differences (MD) and standard deviations or as risk difference and 95 % confidence intervals (CIs). Ten trials comprised 660 total knee arthroplastys and three trials comprised 122 total hip arthroplastys (THAs) met the inclusion criteria. Blood loss was significantly decreased by cryotherapy (MD = -109.68; 95 % CI -210.92 to -8.44; P = 0.03). Cryotherapy did not increase the risk of adverse effect (n.s.). Cryotherapy decreased pain at the second day of postoperative (MD = -1.32; 95 % CI -2.37 to -0.27; P = 0.0003), but did not decreased pain at the first and third day of postoperative (n.s.). Cryotherapy appears effective in these selected patients after joint arthroplasty. The benefits of cryotherapy on blood loss after joint arthroplasty were obvious. However, the subgroup analysis indicated that cryotherapy did not decreased blood loss after THA. Cryotherapy did not increase the risk of adverse effect. Cryotherapy decreased pain at the second day of postoperative, but did not decreased pain at the first and third day of postoperative. II.

It is believed that patients who undergo thyroidectomy for Graves' disease are more likely to experience postoperative hypocalcemia than patients undergoing total thyroidectomy for other indications. However, no study has directly compared these two groups of patients. The aim of this study was to determine whether there was an increased incidence or severity of postoperative hypocalcemia in patients who underwent thyroidectomy for Graves' disease. An institutional review board-approved database was created of all patients who underwent thyroidectomy from 1998 to 2009 at the Johns Hopkins Hospital. There were a total of 68 patients with Graves' disease who underwent surgery. Fifty-five patients who underwent total thyroidectomy were randomly selected and served as control subjects. An analysis was conducted that examined potential covariates for postoperative hypocalcemia, including age, gender, ethnicity, preoperative alkaline phosphatase level, size of goiter, whether parathyroid tissue or glands were present in the specimen, and the reason the patient underwent surgery. Specific outcomes examined were calcium levels on postoperative day 1, whether or not patients experienced symptoms of hypocalcemia, whether or not Rocaltrol was required, the number of calcium tablets prescribed upon discharge, whether or not postoperative tetany occurred, and calcium levels 1 month after discharge. Each outcome was analyzed using a logistic regression. Graves' disease patients had a significantly (p-value < 0.001) higher odds of greater number of calcium tablets prescribed upon discharge. Further, 6 of 68 patients with Graves' disease and no patient in the control group were readmitted with tetany (p = 0.033). There was a trend, though not significant, toward patients with Graves' disease having a higher prevalence of hypocalcemia the day after thyroidectomy and 1 month later. Patients with Graves' disease are more likely to require increased dosages of calcium as well as

Tam, Louisa; Chung, Yin-Yin

2016-01-01

Night extension splinting has been used to treat patients with Dupuytren contracture to improve active range of motion (AROM) of the hand. A published case study demonstrated the benefit of splinting following needle aponeurotomy; however, no larger studies have evaluated the impact of postoperative splinting. To compare the impact of night extension splinting on AROM, specifically extension, following needle aponeurotomy for Dupuytren contracture. A retrospective chart review was conducted in which the charts of 53 patients who underwent needle aponeurotomy for Dupuytren contracture between 2009 and 2013 were reviewed. The control group consisted of patients who underwent needle aponeurotomy only, whereas the treatment group was also referred for fabrication of custom night extension splints after surgery. Comparisons in pre- and postoperative AROM measurements for the metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints were made between both groups of patients. The degrees of change in AROM for each joint were categorized in terms of levels of change: mild (0° to 29°); moderate (30° to 60°); and significant (≥61°). All patients exhibited increased AROM after surgery for both MCP and PIP joints. Both groups had a greater increase in AROM in the MCP joint. Twelve joints from the control group had moderate changes and two from the treatment group had significant changes. When both groups were compared, the levels of change of AROM between both groups did not vary significantly. Night extension splinting following needle aponeurotomy may not improve AROM of the MCP or PIP joints.

The objectives of this study are to survey the weight-bearing limitation practices and delay for returning to running and impact sports of high volume hip arthroscopy orthopedic surgeons. The study was designed in the form of expert survey questionnaire. Evidence-based data are scares regarding hip arthroscopy post-operative weight-bearing protocols. An international cross-sectional anonymous Internet survey of 26 high-volume hip arthroscopy specialized surgeons was conducted to report their weight-bearing limitations and rehabilitation protocols after various arthroscopic hip procedures. The International Society of Hip Arthroscopy invited this study. The results were examined in the context of supporting literature to inform the studies suggestions. Four surgeons always allow immediate weight bearing and five never offer immediate weight bearing. Seventeen surgeons provide weight bearing depending on the procedures performed: 17 surgeons allowed immediate weight bearing after labral resection, 10 after labral repair and 8 after labral reconstruction. Sixteen surgeons allow immediate weight bearing after psoas tenotomy. Twenty-one respondents restrict weight bearing after microfracture procedures for 3-8 weeks post-operatively. Return to running and impact sports were shorter for labral procedures and bony procedures and longer for cartilaginous and capsular procedures. Marked variability exists in the post-operative weight-bearing practices of hip arthroscopy surgeons. This study suggests that most surgeons allow immediate weight bearing as tolerated after labral resection, acetabular osteoplasty, chondroplasty and psoas tenotomy. For cartilage defect procedures, 6 weeks or more non-weight bearing is suggested depending on the area of the defect and lateral central edge angle. Delayed return to sports activities is suggested after microfracture procedures. The level of evidence was Level V expert opinions.

To study the impact on postoperative costs of a patient's antithrombin levels associated with outcomes after cardiac surgery with extracorporeal circulation. An analytic decision model was designed to estimate costs and clinical outcomes after cardiac surgery in a typical patient with low antithrombin levels (<63.7%) compared with a patient with normal antithrombin levels (≥63.7%). The data used in the model were obtained from a literature review and subsequently validated by a panel of experts in cardiothoracic anesthesiology. Multi-institutional (14 Spanish hospitals). Consultant anesthesiologists. A sensitivity analysis of extreme scenarios was carried out to assess the impact of the major variables in the model results. The average cost per patient was €18,772 for a typical patient with low antithrombin levels and €13,881 for a typical patient with normal antithrombin levels. The difference in cost was due mainly to the longer hospital stay of a patient with low antithrombin levels compared with a patient with normal levels (13 v 10 days, respectively, representing a €4,596 higher cost) rather than to costs related to the management of postoperative complications (€215, mostly owing to transfusions). Sensitivity analysis showed a high variability range of approximately ±55% of the base case cost between the minimum and maximum scenarios, with the hospital stay contributing more significantly to the variation. Based on this analytic decision model, there could be a marked increase in the postoperative costs of patients with low antithrombin activity levels at the end of cardiac surgery, mainly ascribed to a longer hospitalization.

Early walking as part of a perioperative care program benefits patients who have had surgery. However, the impact of early walking by itself on the mental and physical recovery of postoperative patients has not been examined. We established a program called walking to recovery (WTR) in which college volunteers provided walking assistance to patients recovering after abdominal surgery. Patients who participated in the program were compared with patients who did not. The postoperative recovery profile survey (PRP-17) was administered on day of discharge to 15 participants and 15 non-participants. Medical records were reviewed to obtain indication for surgery, type of surgery, length of hospital stay, and postoperative complications. At 1 month post-discharge, a short form (SF)-12v2 questionnaire was administered by telephone to assess postoperative quality of life as defined by mental and physical level of function and measured with the mental component score (MCS) and the physical component score (PCS). The average age of participants and non-participants was similar (48.9 ± 9.8 vs. 51.4 ± 8.7 years; p = 0.28). When the two groups were approximately matched by type and severity of surgery, participants had lower PRP-17 composite scores (9.9 vs. 12.5, p = 0.003) and higher indicator sums (9.8 vs. 8.4, p = 0.04) than non-participants, both of which indicate better postoperative recovery in participants. The mean immobilization score was significantly lower in participants (0.3 vs. 0.8, p = 0.04). Postoperative length of stay and MCS did not differ between the two groups, but in participants there was a trend for higher scores in the PCS. Walking with volunteers was associated with a better PRP during the hospitalization period but not at 1 month follow-up. The WTR program is a sustainable, cost-effective model program for other hospitals to emulate as part of the standard of care of postoperative patients.

Hospital readmission after major thoracic surgery has a marked effect on health care delivery, particularly in the era of value-based reimbursement. We sought to investigate the additive impact of comorbidity and postoperative complications on the risk of readmission after thoracic lobectomy. We queried the Nationwide Readmission Database of the Healthcare Cost and Utilization Project between 2010 and 2014 for discharges after pulmonary lobectomy with a primary diagnosis of lung cancer. We compared 90-day all-cause readmission rates across the presence of Elixhauser comorbidities and postoperative complications. Adjusted logistic and linear regression, accounting for patient and hospital factors were used to calculate the mean change in readmission rate by the number of comorbidities and postoperative complications. A total of 87,894 patients undergoing pulmonary lobectomies were identified during the study period, of whom 15,858 (18.0%) were readmitted for any cause within 90 days of discharge. After adjusting for other factors, each additional comorbidity and postoperative complication were associated with a 2.0% and 2.7% increased probability of readmission, respectively (both P < .0001). Patients with a low burden of low comorbidities were readmitted more frequently for postoperative complications, while those with a high burden of comorbidities were readmitted more frequently for chronic disease. Among patients with the lowest risk profile, there was an 11.7% readmission rate. Adjusting for other factors, each additional comorbidity and complication increased this rate by approximately 2.0% and 2.7%, respectively. These results demonstrate that the avoidance of postoperative complications may represent an effective mechanism for decreasing readmissions after thoracic surgery. Copyright © 2018 Elsevier Inc.

Preoperative carbohydrate (CHO) reduces perioperative insulin resistance and improves preoperative patient comfort. We tested the hypotheses that preoperative CHO reduces the risk of postoperative nausea and vomiting (PONV) and improves early postoperative patient comfort. Two hundred women scheduled for thyroidectomy were randomly allocated to drink 50 g CHO in 400 ml of water or 0.5 g aspartam in 100 ml of water 2 h before surgery. The incidence and the severity of PONV, pain scores, and analgesic consumption were recorded postoperatively. Intensity of thirst, hunger, anxiety, fatigue were recorded on 100-mm visual analog scales just before the induction of anesthesia, 2, 6, and 24 h postoperatively. The incidence and severity of PONV were similar in both groups. Patients from the CHO group reported significantly less thirst (P = 0.007), hunger (P = 0.04), and fatigue (P = 0.01) than patients from the control group. Postoperative pain scores did not differ significantly between both groups (P = 0.34). However patients from the CHO group requested less acetaminophen during the first 24 postoperative h: 3 g vs. 2 g (median, P = 0.002). Oral carbohydrate before thyroidectomy improves pre- and postoperative patient comfort, as well as postoperative analgesia, but has no effect on the PONV.

Previous studies have suggested that there may be long-term harm associated with postoperative complications. Uncertainty exists however, because of the need for risk adjustment and inconsistent definitions of postoperative morbidity. We did a longitudinal observational cohort study of patients undergoing major surgery. Case-mix adjustment was applied and morbidity was recorded using a validated outcome measure. Cox proportional hazards modelling using time-dependent covariates was used to measure the independent relationship between prolonged postoperative morbidity and longer term survival. Data were analysed for 1362 patients. The median length of stay was 9 days and the median follow-up time was 6.5 yr. Independent of perioperative risk, postoperative neurological morbidity (prevalence 2.9%) was associated with a relative hazard for long-term mortality of 2.00 [P=0.001; 95% confidence interval (CI) 1.32-3.04]. Prolonged postoperative morbidity (prevalence 15.6%) conferred a relative hazard for death in the first 12 months after surgery of 3.51 (P<0.001; 95% CI 2.28-5.42) and for the next 2 yr of 2.44 (P<0.001; 95% CI 1.62-3.65), returning to baseline thereafter. Prolonged morbidity after surgery is associated with a risk of premature death for a longer duration than perhaps is commonly thought; however, this risk falls with time. We suggest that prolonged postoperative morbidity measured in this way may be a valid indicator of the quality of surgical healthcare. Our findings reinforce the importance of research and quality improvement initiatives aimed at reducing the duration and severity of postoperative complications. © The Author 2014.

Optimising postoperative pain management in the ambulatory patient.

PubMed

Shang, Allan B; Gan, Tong J

2003-01-01

Over 60% of surgery is now performed in an ambulatory setting. Despite improved analgesics and sophisticated drug delivery systems, surveys indicate that over 80% of patients experience moderate to severe pain postoperatively. Inadequate postoperative pain relief can prolong recovery, precipitate or increase the duration of hospital stay, increase healthcare costs, and reduce patient satisfaction. Effective postoperative pain management involves a multimodal approach and the use of various drugs with different mechanisms of action. Local anaesthetics are widely administered in the ambulatory setting using techniques such as local injection, field block, regional nerve block or neuraxial block. Continuous wound infusion pumps may have great potential in an ambulatory setting. Regional anaesthesia (involving anaesthetising regional areas of the body, including single extremities, multiple extremities, the torso, and the face or jaw) allows surgery to be performed in a specific location, usually an extremity, without the use of general anaesthesia, and potentially with little or no sedation. Opioids remain an important component of any analgesic regimen in treating moderate to severe acute postoperative pain. However, the incorporation of non-opioids, local anaesthetics and regional techniques will enhance current postoperative analgesic regimens. The development of new modalities of treatment, such as patient controlled analgesia, and newer drugs, such as cyclo-oxygenase-2 inhibitors, provide additional choices for the practitioner. While there are different routes of administration for analgesics (e.g. oral, parenteral, intramuscular, transmucosal, transdermal and sublingual), oral delivery of medications has remained the mainstay for postoperative pain control. The oral route is effective, the simplest to use and typically the least expensive. The intravenous route has the advantages of a rapid onset of action and easier titratibility, and so is recommended for the

Pain may be associated with postoperative cognitive dysfunction (POCD); however, this relationship remains under investigated. Therefore, we examined the impact of postoperative pain on cognitive functions in aged animals. Rats were allocated to the following groups: control (C), 1.2 % isoflurane for 2 hours alone (I), I with laparotomy (IL), IL with analgesia using local ropivacaine (IL+R), and IL with analgesia using systemic morphine (IL+M). Pain was assessed by rat grimace scale (RGS). Spatial memory was evaluated using a radial maze from postoperative days (POD) 3 to 14. NMDA receptor (NR) 2 subunits in hippocampus were measured by ELISA. Finally, effects of memantine, a low-affinity uncompetitive N-methyl-d-aspartate (NMDA) receptor antagonist, on postoperative cognitive performance were tested. Postoperative RGS was increased in Group IL, but not in other groups. The number of memory errors in Group I were comparable to that in Group C, whereas errors in Group IL were increased. Importantly, in Group IL+R and IL+M, cognitive impairment was not found. The memory errors were positively correlated with the levels of NMDA receptor 2 subunits in hippocampus. Prophylactic treatment with memantine could prevent the development of memory deficits observed in Group IL without an analgesic effect. Postoperative pain contributes to the development of memory deficits after anesthesia and surgery via up-regulation of hippocampal NMDA receptors. Our findings suggest that postoperative pain management may be important for the prevention of POCD in elderly patients. Copyright © 2013 Elsevier Inc. All rights reserved.

Three-dimensional datasets acquired using computed tomography and magnetic resonance imaging are ideally suited for characterization of the aortic root. These modalities offer different advantages and limitations, which must be weighed according to the clinical context. This article provides an overview of current aortic root imaging, highlighting normal anatomy, pathologic conditions, imaging techniques, measurement thresholds, relevant surgical procedures, postoperative complications and potential imaging pitfalls. Patients with a range of clinical conditions are predisposed to aortic root disease, including Marfan syndrome, bicuspid aortic valve, vascular Ehlers-Danlos syndrome, and Loeys-Dietz syndrome. Various surgical techniques may be used to repair the aortic root, including placement of a composite valve graft, such as the Bentall and Cabrol procedures; placement of an aortic root graft with preservation of the native valve, such as the Yacoub and David techniques; and implantation of a biologic graft, such as a homograft, autograft, or xenograft. Potential imaging pitfalls in the postoperative period include mimickers of pathologic processes such as felt pledgets, graft folds, and nonabsorbable hemostatic agents. Postoperative complications that may be encountered include pseudoaneurysms, infection, and dehiscence. Radiologists should be familiar with normal aortic root anatomy, surgical procedures, and postoperative complications, to accurately interpret pre- and postoperative imaging performed for evaluation of the aortic root.

The purpose of this study was to compare postoperative pain and neuropathy after primary caesarean sections with either blunt or sharp fascial expansions. A total of 123 women undergoing primary caesarean sections were included in the study. The sharp group had 61 patients, and the blunt group had 62. In the sharp group, the fascia was incised sharply and extended using scissors. In blunt group, the fascia was bluntly opened by lateral finger-pulling. The primary outcome was postoperative pain. The long-term chronic pain scores were significantly lower in the blunt group during mobilisation (p = .012 and p = .022). Neuropathy was significantly more prevalent in the sharp group at both 1 and 3 months postoperatively (p = .043 and p = .016, respectively). The odds ratio (OR) and 95%CI for postoperative neuropathy at 1 and 3 months were as follows; OR 3.71, 95%CI 0.97-14.24 and OR 5.67, 95%CI 1.18-27.08, respectively. The OR for postoperative pain after 3 months was 3.26 (95%CI 1.09-9.73). The prevelance of postsurgical neuropathy and chronic pain at 3 months were significantly lower in the blunt group. Blunt fascial opening reduces the complication rate of postoperative pain and neuropathy after caesarean sections. Impact statement What is already known on this subject? The anatomic relationship of the abdominal fascia and the anterior abdominal wall nerves is a known fact. The fascia during caesarean sections can be opened by either a sharp or blunt extension. Data on the isolated impact of different fascial incisions on postoperative pain is limited. What do the results of this study add? The postoperative pain scores on the incision area are lower in the bluntly opened group compared to the sharp fascial incision group. By extending the fascia bluntly, a decrease in trauma and damage to nerves was observed. What are the implications of these findings for clinical practice and/or future research? The lateral extension of the fascia during

Objective: The aim of the following study is to determine the effect of primary closure or dressing on post-operative morbidity after impacted lower third molar surgery. Materials and Methods: This was a randomized clinical study of 72 patients who had surgical extraction of impacted mandibular third molars. The subjects were divided into two groups of A and B. Group A had total closure (primary closure) and Group B had whitehead varnish dressing of the socket. Pain, swelling and trismus were evaluated pre-operatively using visual analogue scale, flexible tape measuring method and inter-incisal distance measurement with Vernier Callipers respectively as well as post-operatively on 1st, 2nd, 3rd, 5th and 7th day. Results: The study participants consisted of 27 males and 45 females in a ratio 1:1.7. With a mean age of 24.7 ± 4.9 years (range 19-33 years) for Group A and 25.5 ± 4.3 years (range 20-39 years) for Group B. Post-operative pain was not significantly affected by the closure techniques (P > 0.05). Dressing was found to significantly reduce the degree of swelling and trismus peaking on the 2nd day (P = 0.0207 and P = 0.010 respectively). Conclusion: The use of dressing was more effective than primary closure to reduce the degree of swelling and trismus though its effect on post-operative pain reduction was not significant.

Context Post-operative atrial fibrillation/flutter (AF) is one of the most common complications of cardiac surgery and significantly increases morbidity and healthcare utilization. A few small trials have evaluated whether long-chain n-3-polyunsaturated fatty acids (PUFA) reduce post-op AF, with mixed results. Objective To determine whether peri-operative n-3-PUFA supplementation reduces post-op AF. Design Randomized, double-blind, placebo-controlled, multinational, clinical trial. Patients A total of 1,516 patients scheduled for cardiac surgery across 28 centers in the US, Italy, and Argentina, enrolled between Aug 2010 and Jun 2012. Inclusion criteria were broad; the main exclusions were regular use of fish oil or absence of sinus rhythm at enrollment. Forty-eight percent of screened patients and 94% of eligible patients were enrolled. Intervention Patients were randomized to receive fish oil (1 g capsules containing ≥840 mg n-3-PUFA as ethyl esters) or placebo, with pre-operative loading of 10g over 3-5 days (or 8g over 2 days) followed post-operatively by 2g/d until hospital discharge or post-op day10, whichever first. Main Outcome Measures The primary endpoint was occurrence of post-op AF >30 sec. We also evaluated post-op AF lasting >1hr, resulting in symptoms, or treated with cardioversion; other secondary post-op AF endpoints; other tachyarrhythmias; hospital utilization; and major adverse cardiovascular events, 30-day mortality, bleeding, and other adverse events. All endpoints and analyses plans were prespecified. Results At enrollment, mean±SD age was 64±13 years, 72.2% were male, and 51.8% had planned valvular surgery. The primary endpoint occurred in 233 (30.7%) and 227 (30.0%) patients assigned to placebo and n-3-PUFA, respectively (OR=0.96, 95%CI=0.77-1.20; P=0.74). None of the secondary endpoints were significantly different, including post-op AF that was sustained, symptomatic, or treated (n=231 [30.5%] vs. n=224 [29.6%], P=0.70) or number of

Improved life-expectancies have seen increased rates of older patients undergoing surgery worldwide. These patients are at increased risk of post-operative complications. Australian evidence is limited regarding the association between age and post-operative outcomes, especially rapid response calls (RRCs) as indicators of adverse outcomes. The aim was to compare the post-operative outcomes of older patients (≥80 years) to younger patients. Specifically, 30-day in-hospital mortality; unplanned intensive care unit (ICU) admission; and RRC activation within 72 h post-operatively. Single-centre retrospective observational study conducted over 12 months in a metropolitan Australian hospital. All adult patients (≥16 years) undergoing surgical procedures were included, excluding cardiac and obstetric/gynaecological surgeries. Patient co-morbidities were quantified using Charlson co-morbidity index (CCI) and American Society of Anesthesiologists physical status classification. Seven thousand four hundred and seventy-nine patients met inclusion criteria, 14.5% (n = 1086) aged ≥80 years. Most procedures (65%) were elective; and general surgical procedures were most common (24.2%). Compared to younger patients, older patients had significantly higher 30-day mortality (2.3% versus 0.2%; P < 0.001), increased post-operative RRC rates (7.3% versus 1.2%; P < 0.001), and unplanned ICU admissions (3.2% versus 1.6%; P < 0.001). Increasing age was associated with increased risk of post-operative RRC, unplanned ICU admission, and in-hospital mortality (all P < 0.01), with associations remaining significant after controlling for surgery type and CCI. Older patients are at increased risk of adverse post-operative outcomes, including post-operative RRC, unplanned ICU admission, and mortality, especially if they underwent emergency procedures. This has implications for preoperative risk stratification and post-operative management. Incidence of post-operative

Background Recently, the use of smartphones to deliver health-related content has experienced rapid growth, with more than 165,000 mobile health (mHealth) apps currently available in the digital marketplace. With 3 out of 4 Canadians currently owning a smartphone, mHealth apps offer opportunities to deliver accessible health-related knowledge and support. Many individuals experience pain after surgery, which can negatively impact their health-related quality of life, including sleep, emotional, and social functioning. Smartphone apps that provide remote real-time monitoring and symptom management have the potential to improve self-management skills in patients experiencing postoperative pain. Increased confidence and practice of self-management skills could contribute to decreased postoperative pain and reduce risk of developing persistent pain. Published reviews of general pain self-management apps demonstrate a lack of evidence-based content, theoretical grounding, and health care professional involvement. However, no review to date has focused on the app marketplace specific for individuals with postoperative pain. Objective The aim of this study was to characterize and critically appraise the content and functionality of commercially available postoperative pain self-management apps. Methods An electronic search and extraction was conducted between December 2016 and March 2017 of the official Canadian app stores for the three major smartphone operating systems (iPhone operating system [iOS], Android, and Windows). Stores were searched separately using predetermined search terms. Two authors screened apps based on information provided in the public app description. Metadata from all included apps were abstracted into a standard spreadsheet. Two authors verified the data with reference to the apps and downloaded apps themselves. The content and functionality of each app as it pertained to postoperative pain self-management was rated. Results A total of 10 apps

Summary Objectives The authors investigated the impact of computerized provider order entry (CPOE) on the delivery times of analgesia and subsequent patient outcomes. We hypothesized that patients would report less pain and use less pain medications compared with the previous paper-based system. Methods Two groups of patients after a total hip (THA) or knee arthroplasty (TKA) were retrospectively compared: one comprising 106 patients when the paper-based ordering system was in effect (conventional group), and one comprising 96 patients after CPOE was installed (electronic group). All patients received a regional anaesthetic at surgery (combined spinal-epidural). TKA patients also received a single-injection femoral nerve block. After transfer to the postoperative anaesthesia care unit (PACU), a patient-controlled epidural analgesia (PCEA) infusion was initiated. The following data was collected from the PACU record: time to initiation of analgesia, visual analog scale (VAS) pain scores at initiation of analgesia and hourly for the first postoperative day (POD), volume of pain medication used, length of stay (LOS) in the PACU and the hospital. Results The time to initiation of analgesia from arrival in the PACU was significantly lower in the electronic group compared to the conventional group (24.5 ± 28.3 minutes vs. 51.1 ± 26.2 minutes; mean ± SD, p < 0.001), as were VAS pain scores (0.82 ± 1.08 vs. 1.5 ± 1.52, p < 0.001) and the volume of PCEA needed to control pain (27.9 ± 20.2 ml vs. 34.8 ± 20.3 ml, p = 0.001) at 4 hours postoperatively. PACU LOS and hospital LOS did not significantly differ in the two groups. Conclusions After implementation of CPOE, patients received their postoperative analgesia faster, had less pain, and required less medication. PMID:26448800

To investigate the impact of prognostic nutritional index (PNI) on the postoperative complications and long-term outcomes in gastric cancer patients undergoing total gastrectomy. The data for 386 patients with gastric cancer were extracted and analyzed between January 2003 and December 2008 in our center. The patients were divided into two groups according to the cutoff value of the PNI: those with a PNI ≥ 46 and those with a PNI < 46. Clinicopathological features were compared between the two groups and potential prognostic factors were analyzed. The relationship between postoperative complications and PNI was analyzed by logistic regression. The univariate and multivariate hazard ratios were calculated using the Cox proportional hazard model. The optimal cutoff value of the PNI was set at 46, and patients with a PNI ≥ 46 and those with a PNI < 46 were classified into PNI-high and PNI-low groups, respectively. Patients in the PNI-low group were more likely to have advanced tumor (T), node (N), and TNM stages than patients in the PNI-high group. The low PNI is an independent risk factor for the incidence of postoperative complications (OR = 2.223). The 5-year overall survival (OS) rates were 54.1% and 21.1% for patients with a PNI ≥ 46 and those with a PNI < 46, respectively. The OS rates were significantly lower in the PNI-low group than in the PNI-high group among patients with stages II (P = 0.001) and III (P < 0.001) disease. The PNI is a simple and useful marker not only to identify patients at increased risk for postoperative complications, but also to predict long-term survival after total gastrectomy. The PNI should be included in the routine assessment of advanced gastric cancer patients.

This study aims to evaluate the efficacy of processed images to predict postoperative appearance following levator resection. Analysis involved 109 eyes from 65 patients with blepharoptosis who underwent advancement of levator aponeurosis and Müller's muscle complex (levator resection). Predictive images were prepared from preoperative photographs using the image processing software (Adobe Photoshop ® ). Images of selected eyes were digitally enlarged in an appropriate manner and shown to patients prior to surgery. Approximately 1 month postoperatively, we surveyed our patients using questionnaires. Fifty-six patients (89.2%) were satisfied with their postoperative appearances, and 55 patients (84.8%) positively responded to the usefulness of processed images to predict postoperative appearance. Showing processed images that predict postoperative appearance to patients prior to blepharoptosis surgery can be useful for those patients concerned with their postoperative appearance. This approach may serve as a useful tool to simulate blepharoptosis surgery.

There remains concern that moderate hypothermic circulatory arrest (MHCA) with antegrade cerebral perfusion (ACP) may provide suboptimal distal organ protection compared with deep hypothermic circulatory arrest (DHCA) with retrograde cerebral perfusion (RCP). We compared postoperative acute kidney injury (AKI) in in patients who underwent elective hemiarch repair with either DHCA/RCP or MHCA/ACP. This was a retrospective review of all patients undergoing elective aortic hemiarch reconstruction for aneurysmal disease between 2009 and 2014. Patients were stratified according to the use of DHCA/RCP versus MHCA/ACP. The primary outcome was the occurrence of AKI at 48 hours, as defined by the Risk, Injury, Failure, Loss, End-Stage (RIFLE ) criteria. A multivariable logistic regression identified risk factors for AKI. One hundred eighteen patients who underwent ACP and 471 patients who underwent RCP were included. The mean lowest temperature was 26.4°C in patients who underwent MHCA/ACP and 17.5°C in patients who underwent DHCA/RCP. Baseline demographics were similar except that patients who underwent DHCA/RCP were more likely to have peripheral arterial disease or bicuspid aortic valves. Cardiopulmonary bypass and aortic cross-clamp times were shorter in the MHCA/ACP group. AKI occurred in 19 (16.2%) patients who underwent MHCA/ACP and 67 (14.3%) patients who underwent DHCA/RCP. Four (0.8%) patients who underwent DHCA/RCP required postoperative dialysis. In-hospital mortality tended to increase with increasing RIFLE classification (RIFLE class-0 (No AKI) = 0.41%; Risk = 1.35%, and Injury = 10.0%; p = 0.09). On multivariable analysis, the lowest temperature and cerebral perfusion strategy were not significant predictors of AKI. Lower baseline glomerular filtration rate (GFR), lower preoperative ejection fraction, and longer cardiopulmonary bypass (CPB) time were independently associated with higher AKI. We applied the sensitive RIFLE criteria to examine AKI in

Patients who undergo surgical resection of brain metastases are at significant risk of cavity local recurrence without additional radiation therapy. Postoperative stereotactic radiosurgery (SRS) is a method of focal treatment to the cavity to maximize local control while minimizing the risk of neurocognitive detriment associated with whole brain radiation therapy. Recently published randomized trials have demonstrated the benefit of postoperative SRS in terms of cavity tumor control and preserving neurocognition. However, there are several potential drawbacks with postoperative SRS including a possible increase in symptomatic radiation necrosis because of the need for cavity margin expansion due to target delineation uncertainty, the variable postoperative clinical course and potential delay in administering postoperative SRS, and the theoretical risk of tumor spillage into cerebrospinal fluid at the time of surgery. Preoperative SRS is an alternative paradigm wherein SRS is delivered prior to surgical resection, which may effectively address some of these potential drawbacks. The goal of this review is to examine the rationale, technique, outcomes, evidence, and future directions for the use of SRS as an adjunct to surgical resection. This can be delivered as either preoperative or postoperative SRS with potential advantages and disadvantages to both approaches that will be discussed.

Our study quantifies the effectiveness of perioperative pain control in a cohort of patients undergoing major head and neck surgery with free flap reconstruction. Our long-term goal is to improve pain control and thereby increase mobility, decrease postoperative complications and decrease hospital stay. A retrospective analysis was performed at a tertiary, academic head and neck surgical oncology program in Calgary, Alberta, Canada from January 1, 2015 - December 31, 2015. Pain scores were recorded prospectively. Primary outcomes were frequency of postoperative pain assessments and pain intensity using the numeric rating scale. The cohort included 41 patients. Analysis was limited to pain scores recorded from postoperative days 1-14. There was an average of 7.3 pain measurements per day (SD 4.6, range 1-24) with the most frequent monitoring on postoperative days 1-4. Median pain scores ranged from 0 to 4.5 with the highest median score on postoperative day 6. The daily maximum pain scores recorded ranged from 8 to 10 with scores of 10 recorded on postoperative days 1, 2, 3, 5, 7, 8, and 10. Patients most frequently had inadequate pain control on postoperative days 1, 2, 4, and 5 with the majority occurring on postoperative day 1. Postoperative pain control could be improved at our centre. The frequency of pain assessments is also highly variable. Ongoing measurement, audit, and feedback of analgesic protocol effectiveness is an excellent first step in improving perioperative pain management in patients undergoing major head and neck cancer surgery with free flap reconstruction.

Awake craniotomy pursues a balance between extensive tumor resection and preservation of postoperative language function. A dilemma exists in patients whose tumor resection is restricted due to signs of language impairment observed during awake craniotomy. In order to determine the degree to which recovery of language function caused by tumor resection can be achieved by spontaneous neuroplasticity, the change in postoperative language function was compared to quantified intraoperative linguistic performance. The modified, short-form Boston Diagnostic Aphasia Examination (sfBDAE) was used to assess pre- and postoperative language functions; visual object naming (DO 80) and semantic-association (Pyramid and Palm Tree Test, PPTT) tests assessed intraoperative linguistic performance. DO 80 and PPTT were performed alternatively during subcortical functional monitoring while performing tumor resection and sfBDAE was assessed 1-week postoperatively. Most patients with observed language impairment during awake surgery showed improved language function postoperatively. Both intraoperative DO 80 and PPTT showed significant correlation to postoperative sfBDAE domain scores (p < 0.05), with a higher correlation observed with PPTT. A linear regression model showed that only PPTT predicted the postoperative sfBDAE domain scores with the adjusted R 2 ranging from 0.51 to 0.89 (all p < 0.01). Receiver operating characteristic analysis showed a cutoff value of PPTT that yielded a sensitivity of 80% and specificity of 100%. PPTT may be a feasible tool for intraoperative linguistic evaluation that can predict postoperative language outcomes. Further studies are needed to determine the extent of tumor resection that optimizes the postoperative language following neuroplasticity.

SSI rates after gynecologic oncology surgery vary from 5% to 35%, but are up to 45% in patients with diabetes mellitus (DM). Strict postoperative glucose control by insulin infusion has been shown to lower morbidity, but not specifically SSI rates. Our project studied continuous postoperative insulin infusion for 24h for gynecologic oncology patients with DM and hyperglycemia with a target blood glucose of <139 mL/dL and a primary outcome of the protocol's impact on SSI rates. We compared SSI rates retrospectively among three groups. Group 1 was composed of patients with DM whose blood glucose was controlled with intermittent subcutaneous insulin injections. Group 2 was composed of patients with DM and postoperative hyperglycemia whose blood glucose was controlled by insulin infusion. Group 3 was composed of patients with neither DM nor hyperglycemia. We controlled for all relevant factors associated with SSI. We studied a total of 372 patients. Patients in Group 2 had an SSI rate of 26/135 (19%), similar to patients in Group 3 whose rate was 19/89 (21%). Both were significantly lower than the SSI rate (43/148, 29%) of patients in Group 1. This reduction of 35% is significant (p = 0.02). Multivariate analysis showed an odd ratio = 0.5 (0.28-0.91) in reducing SSI rates after instituting this protocol. Initiating intensive glycemic control for 24h after gynecologic oncology surgery in patients with DM and postoperative hyperglycemia lowers the SSI rate by 35% (OR = 0.5) compared to patients receiving intermittent sliding scale insulin and to a rate equivalent to non-diabetics.

Anti-TNF prevents postoperative Crohn's disease recurrence in most patients but not all. This study aimed to define the relationship between adalimumab pharmacokinetics, maintenance of remission and recurrence. As part of a study of postoperative Crohn's disease management, some patients undergoing resection received prophylactic postoperative adalimumab. In these patients, serum and fecal adalimumab concentration and serum anti-adalimumab antibodies [AAAs] were measured at 6, 12 and 18 months postoperatively. Levels of Crohn's disease activity index [CDAI], C-reactive protein [CRP] and fecal calprotectin [FC] were assessed at 6 and 18 months postoperatively. Body mass index and smoking status were recorded. A colonoscopy was performed at 6 and/or 18 months. Fifty-two patients [32 on monotherapy and 20 on combination therapy with thiopurine] were studied. Adalimumab concentration did not differ significantly between patients in endoscopic remission vs recurrence [Rutgeerts ≥ i2] [9.98µg/mL vs 8.43 µg/mL, p = 0.387]. Patients on adalimumab monotherapy had a significantly lower adalimumab concentration [7.89 µg/mL] than patients on combination therapy [11.725 µg/mL] [p = 0.001], and were significantly more likely to have measurable AAA [31% vs 17%, p = 0.001]. Adalimumab concentrations were lower in patients with detectable AAA compared with those without [3.59 µg/mL vs 12.0 µg/mL, p < 0.001]. Adalimumab was not detected in fecal samples. Adalimumab serum concentrations were lower in obese patients compared with in non-obese patients [p = 0.046]. Adalimumab concentration in patients treated with adalimumab to prevent symptomatic endoscopic recurrence postoperatively is, for most patients, well within the therapeutic window, and is not significantly lower in patients who develop recurrence compared with in those who remain in remission. Mechanisms of anti-TNF failure to prevent postoperative recurrence remain to be determined in these patients.

Postoperative adhesions are pathological attachments that develop between abdominopelvic structures following surgery. Considered unavoidable and ubiquitous, postoperative adhesions lead to bowel obstructions, infertility, pain, and reoperations. As such, they represent a substantial health care challenge. Despite over a century of research, no preventive treatment exists. We hypothesized that postoperative adhesions develop from a lack of movement of the abdominopelvic organs in the immediate postoperative period while rendered immobile by surgery and opiates, and tested whether manual therapy would prevent their development. In a modified rat cecal abrasion model, rats were allocated to receive treatment with manual therapy or not, and their resulting adhesions were quantified. We also characterized macrophage phenotype. In separate experiments we tested the safety of the treatment on a strictureplasty model, and also the efficacy of the treatment following adhesiolysis. We show that the treatment led to reduced frequency and size of cohesive adhesions, but not other types of adhesions, such as those involving intraperitoneal fatty structures. This effect was associated with a delay in the appearance of trophic macrophages. The treatment did not inhibit healing or induce undesirable complications following strictureplasty. Our results support that that maintained movements of damaged structures in the immediate postoperative period has potential to act as an effective preventive for attenuating cohesive postoperative adhesion development. Our findings lay the groundwork for further research, including mechanical and pharmacologic approaches to maintain movements during healing.

The objective of this narrative review was to examine the usage of ketamine as a postoperative analgesic agent across a wide variety of surgeries. A literature search was performed using the phrases "ketamine" and "postoperative pain." The authors analyzed the studies that involved testing ketamine's effectiveness at controlling postoperative pain. Effectiveness was assessed through various outcomes such as the amount of opiate consumption, visual analog scale (VAS) pain scores, and persistent postoperative pain at long-term follow-up. While many different administration protocols were evaluated, delivering ketamine both as a pre- or perioperative bolus and postoperative infusion for up to 48 hours appeared to be the most effective. These effects are dose-dependent. However, a number of studies analyzed showed no benefit in using ketamine versus placebo for controlling postoperative pain. While ketamine is a safe and well-tolerated drug, it does have adverse effects, and there are concerns for possible neurotoxicity and effects on memory. In a number of limited situations, ketamine has shown some efficacy in controlling postoperative pain and decreasing opioid consumption. More randomized controlled trials are necessary to determine the surgical procedures and administrations (i.e., intravenous, epidural) that ketamine is best suited for.

Selection of patients for hepatectomy for hepatocellular carcinoma conventionally has been based upon Child-Pugh grading. However, postoperative liver failure after hepatectomy is a major cause of hospital mortality. A new predictor of postoperative liver failure is required. The objective of this study was to identify risk factors for postoperative liver failure after hepatectomy. Perioperative risk factors for liver failure after hepatectomy were analyzed in 112 patients with hepatocellular carcinoma Eight of these patients died of liver failure. Stepwise multivariate logistic regression was performed to investigate significant independent factors among 17 variables, including the serum alkaline phosphatase ratio (ALPR) on the first day after hepatectomy. ALPR was calculated as the postoperative ALP level divided by the ALP level before surgery. Significant risk factors of postoperative liver failure were ALPR on postoperative day 1 (ALPR1), sex, operative blood loss, and operative procedure. As an indicator of liver failure, the diagnostic accuracy of the ALPR1 was 93.7% when the ALPR was less than 0.4 on the first postoperative day. The ALPR and the serum total bilirubin concentration after hepatectomy were uncorrelated. ALPR1 is a useful predictor of liver failure after hepatectomy.

Nasal packing is associated with post-operative Eustachian tube dysfunction in patients undergoing nasal surgical procedures. The effect of cannulated nasal packs which may improve nasopharyngeal ventilation was investigated in a prospective randomized controlled trial. Adult elective patients without tympanometric evidence of pre-operative Eustachian tube dysfunction were recruited. All subjects underwent single or combined intranasal surgical procedures and were randomized to receive either bilateral cannulated or non-cannulated Merocel nasal packs. Middle ear pressures (MEP) were recorded pre-operatively and post-operatively before nasal pack removal. Left and right ear results were amalgamated for analysis and 40 adults, 20 in each group were analysed. There was no difference in pre-operative MEP, -15 dPa (median value) in both groups. Post-operatively the MEP changed in both groups P < 0.0001. There was no significant inter group difference in the post-operative median MEP, -85 dPa in the cannulated and -70 dPa in the control groups, (95% c.i. for the difference in the medians -25-55 dPa). Nasal surgery with post-operative packing leads to an objective reduction in MEP which is not altered by venting the packs.

Postoperative insulin resistance is a well-characterized metabolic state that has been shown to correlate with the length of postoperative stay in hospital. Preoperative intravenous or oral carbohydrate treatment has been shown to attenuate the development of postoperative insulin resistance measured 1 day after surgery. To study the effects of preoperative oral carbohydrate treatment on postoperative changes in insulin resistance and substrate utilization, in the absence of postoperative confounding factors, 15 patients were double-blindly treated with either a carbohydrate-rich beverage (12.5%) (n = 8) or placebo (n = 7) before undergoing total hip replacement surgery. Insulin sensitivity, endogenous glucose release, and substrate oxidation rates were measured before and immediately after surgery. Whole body insulin sensitivity decreased by 18% in the treatment group vs. 43% in the placebo group (P < 0.05, Student's t-test for unpaired data). In both groups, the major mechanism of insulin resistance was an inhibition of insulin-induced nonoxidative glucose disposal after surgery. The better preservation of insulin sensitivity in the treatment group was attributable to a less reduced glucose disposal in peripheral tissues and increased glucose oxidation rates.

Cerebrospinal fluid (CSF) hypovolemia is a common neurosurgical condition, which may be spontaneous or iatrogenic. At our institution, a substantial number of the reported cases of early post-operative CSF hypovolemia were identified to have unintentional or unrecognized post-operative continuous excessive CSF leakage. Cases who presented with post-operative CSF hypovolemia several days after uneventful intracranial surgeries without continuous CSF leakage were rarely reported. A retrospective review of the medical records of these patients was performed to identify those patients who developed early post-operative CSF hypovolemia without the presence of post-operative continuous CSF leakage. A total of 7 patients, 5 of which were males, were identified in this retrospective study. They experienced CSF hypovolemia between days 1 and 7 after emergency or scheduled intracranial surgeries. Ventricular collapse, cisternal effacement and midline shift are the most common radiological observations. With early diagnosis and management, 4 of the patients achieved a Glasgow Outcome Scale (GOS) score of 5, 1 achieved a GOS score of 4 and the remaining 2 had a GOS score of 3. No mortality was noted in this series. Although rare in incidence, early post-operative CSF hypovolemia may occur without the existence of post-operative continuous CSF leakage. When the diagnosis of CSF hypovolemia is reached, factors that may exacerbate CSF compensation should be promptly terminated. Trendelenburg position and sufficient intravenous hydration are practical and effective managements, and CSF hypovolemia may thereby be reversed in a substantial number of patients.

Hypocalcaemia is a complication of parathyroidectomy. We retrospectively analyzed data on patients who underwent parathyroidectomy for primary hyperparathyroidism (pHPT) to identify predictive factors for severe postoperative hypocalcaemia. Since 2004 we performed 87 parathyroidectomies for pHPT. We divided the patients into two groups: subjects who presented with postoperative hypocalcaemia (group B) or otherwise (group A). We looked for a correlation between several variables and the incidence of postoperative hypocalcaemia. The median calcemia in group B (19 patients) was 6.9 mg/dL on the first postoperative day and 7.6 mg/dL on the third day. We observed hypocalcemia related clinical symptoms in every patient. In all 19 cases the reduction of intraoperative parathyroid hormone above 85 per cent after parathyroidectomy was related to the development of severe postoperative hypocalcaemia (P = 0.042). We found that the reduction of intraoperative parathyroid hormone over 85 per cent after parathyroidectomy can be considered a reliable predictive factor of postoperative hypocalcaemia after parathyroidectomy for primary hyperparathyroidism.

Purpose This study aims to evaluate the efficacy of processed images to predict postoperative appearance following levator resection. Methods Analysis involved 109 eyes from 65 patients with blepharoptosis who underwent advancement of levator aponeurosis and Müller’s muscle complex (levator resection). Predictive images were prepared from preoperative photographs using the image processing software (Adobe Photoshop®). Images of selected eyes were digitally enlarged in an appropriate manner and shown to patients prior to surgery. Results Approximately 1 month postoperatively, we surveyed our patients using questionnaires. Fifty-six patients (89.2%) were satisfied with their postoperative appearances, and 55 patients (84.8%) positively responded to the usefulness of processed images to predict postoperative appearance. Conclusion Showing processed images that predict postoperative appearance to patients prior to blepharoptosis surgery can be useful for those patients concerned with their postoperative appearance. This approach may serve as a useful tool to simulate blepharoptosis surgery. PMID:27757008

Questions persist about the management of postoperative chylothorax in infants and children. Our experience with postoperative chylothorax over the most recent decade (1980 to 1990) has been reviewed. The type and amount of drainage, data from cardiac catheterization and echocardiography, operative decisions and details, and eventual outcomes have been cataloged. All patients were initially treated with total gut rest, with operation reserved for unabated drainage. Chylothorax developed postoperatively in 15 infants and 11 children (18 with a cardiac procedure and 8 with a noncardiac procedure). The average age was 3.1 years. Spontaneous cessation and cure occurred in 19 (73.1%) of these 26 patients, with an average drainage duration of 11.9 days (range, 4 to 30 days). Those for whom operation was chosen drained preoperatively for an average of 29.2 days (range, 25 to 40 days). There were no deaths in either group. Complications were lymphopenia (2 patients) and fungal sepsis (1 patient). The amount of drainage per day was not significantly different between patients treated operatively and those treated nonoperatively. Failure of nonoperative management was associated with venous hypertension from increased right-sided cardiac pressures or central venous thrombosis (p < 0.05, Fisher's exact test). Presumably this increased pressure is transmitted to the lymphatic system. These patients should be identified early and considered for thoracic duct suture or pleuroperitoneal shunting.

Cardiac surgery (CS) ranks among the most frequently performed interventions worldwide and persistent postoperative pain (PPP) has been recognized as a relevant clinical outcome in this context. We aimed to evaluate its incidence, characteristics, associated factors and patient's quality of life (QoL). Observational prospective study conducted in patients undergoing CS in a tertiary university hospital. PPP was defined as persistent pain after surgery with higher than 3 months' duration, after excluding other causes of pain. We used a set of questionnaires for data collection: Pain Catastrophizing Scale, Duke Health Profile, Brief Pain Inventory Short Form, McGill Pain Questionnaire Short Form, Douleur Neuropathique en 4 Questions and standardized questions regarding pain periodicity. A total of 288 patients have completed the study and 43% presented PPP assessed at 3 months (PPP3M); out of which 84% were not under any treatment. PPP patients reported significantly lower QoL, and a neuropathic pain (NP) component was present in 50% of them. Younger age, female gender, higher body mass index, catastrophizing, coronary artery bypass graft, osteoarthritis, history of previous surgery (excluding sternotomy) and moderate to severe acute postoperative pain were independent predictors of PPP3M. This is the first study comprehensively describing PPP after CS and identifying NP in half of them. Our results support the important role that PPP plays after CS in considering its interference in patients' daily life and their lower QoL, which deserves the attention of health care professionals in order to improve prevention, assessment and treatment of these patients. WHAT DOES THIS STUDY ADD?: This study comprehensively describes persistent postoperative pain (PPP) after cardiac surgery (CS) and identifies neuropathic pain (NP) in half of them. Our results support the important role that PPP plays after CS in considering its interference in patients' daily life and their

Colorectal cancer is one of the most common types of cancer in the Western world. Apart from surgery - which remains the mainstay of treatment for resectable primary tumours - postoperative (i.e., adjuvant) chemotherapy with 5-fluorouracil (5-FU) based regimens is now the standard treatment in Dukes' C (TNM stage III) colon tumours i.e. tumours with metastases in the regional lymph nodes but no distant metastases. In contrast, the evidence for recommendations of adjuvant therapy in rectal cancer is sparse. In Europe it is generally acknowledged that locally advanced rectal tumours receive preoperative (i.e., neoadjuvant) downstaging by radiotherapy (or chemoradiotion), whereas in the US postoperative chemoradiotion is considered the treatment of choice in all Dukes' C rectal cancers. Overall, no universal consensus exists on the adjuvant treatment of surgically resectable rectal carcinoma; moreover, no formal systematic review and meta-analysis has been so far performed on this subject. We undertook a systematic review of the scientific literature from 1975 until March 2011 in order to quantitatively summarize the available evidence regarding the impact of postoperative adjuvant chemotherapy on the survival of patients with surgically resectable rectal cancer.

Post-Operative Cognitive Dysfunction (POCD) is a highly prevalent condition with significant clinical, social and financial impacts for patients and their communities. The underlying pathophysiology is becoming increasingly understood, with the role of neuroinflammation and oxidative stress secondary to surgery and anaesthesia strongly implicated. This review aims to describe the putative mechanisms by which surgery-induced inflammation produces cognitive sequelae, with a focus on identifying potential novel therapies based upon their ability to modify these pathways.

Objective To evaluate the impact of the renal dysfunction (RD) type and change of postoperative cardiac function on the risk of developing acute kidney injury (AKI) in patients who underwent cardiac valve surgery. Method Reversible renal dysfunction (RRD) was defined as preoperative RD in patients who had not been initially diagnosed with chronic kidney disease (CKD). Cardiac function improvement (CFI) was defined as postoperative left ventricular ejection function – preoperative left ventricular ejection function (ΔEF) >0%, and cardiac function not improved (CFNI) as ΔEF ≤0%. Results Of the 4,805 (94%) cardiac valve surgery patients, 301 (6%) were RD cases. The AKI incidence in the RRD group (n=252) was significantly lower than in the CKD group (n=49) (36.5% vs 63.3%, P=0.018). The AKI and renal replacement therapy incidences in the CFI group (n=174) were significantly lower than in the CFNI group (n=127) (33.9% vs 50.4%, P=0.004; 6.3% vs 13.4%, P=0.037). After adjustment for age, gender, and other confounding factors, CKD and CKD + CFNI were identified as independent risk factors for AKI in all patients after cardiac valve surgery. Multivariate logistic regression analysis showed that the risk factors for postoperative AKI in preoperative RD patients were age, gender (male), hypertension, diabetes, chronic heart failure, cardiopulmonary bypass time (every 1 min added), and intraoperative hypotension, while CFI after surgery could reduce the risk. Conclusion For cardiac valve surgery patients, preoperative CKD was an independent risk factor for postoperative AKI, but RRD did not add to the risk. Improved postoperative cardiac function can significantly reduce the risk of postoperative AKI. PMID:29184415

Transversus abdominis plane (TAP) block is a locoregional anaesthesia technique of growing interest in abdominal surgery. However, its efficacy following laparoscopic colorectal surgery is still debated. This meta-analysis aimed to assess the efficacy of TAP block after laparoscopic colorectal surgery. All comparative studies focusing on TAP block after laparoscopic colorectal surgery have been systematically identified through the MEDLINE database, reviewed and included. Meta-analysis was performed according to the Mantel-Haenszel method for random effects. End-points included postoperative opioid consumption, morbidity, time to first bowel movement and length of hospital stay. A total of 13 studies, including 7 randomized controlled trials, were included, comprising a total of 600 patients who underwent laparoscopic colorectal surgery with TAP block, compared with 762 patients without TAP block. Meta-analysis of these studies showed that TAP block was associated with a significantly reduced postoperative opioid consumption on the first day after surgery [weighted mean difference (WMD) -14.54 (-25.14; -3.94); P = 0.007] and a significantly shorter time to first bowel movement [WMD -0.53 (-0.61; -0.44); P < 0.001] but failed to show any impact on length of hospital stay [WMD -0.32 (-0.83; 0.20); P = 0.23] although no study considered length of stay as its primary outcome. Finally, TAP block was not associated with a significant increase in the postoperative overall complication rate [OR = 0.84 (0.62-1.14); P = 0.27]. Transversus abdominis plane (TAP) block in laparoscopic colorectal surgery improves postoperative opioid consumption and recovery of postoperative digestive function without any significant drawback.

Postoperative radiotherapy to the craniospinal axis is standard-of-care for pediatric medulloblastoma but is associated with long-term morbidity, particularly in young children. With the advent of modern adjuvant chemotherapy strategies, postoperative radiotherapy deferral has gained acceptance in children younger than 3 years, although it remains controversial in older children. To analyze recent postoperative radiotherapy national treatment patterns and implications for overall survival in patients with medulloblastoma ages 3 to 8 years. Using the National Cancer Data Base, patients ages 3 to 8 years diagnosed as having histologically confirmed medulloblastoma in 2004 to 2012, without distant metastases, who underwent surgery and adjuvant chemotherapy with or without postoperative radiotherapy at facilities nationwide accredited by the Commission on Cancer were identified. Patients were designated as having "postoperative radiotherapy upfront" if they received radiotherapy within 90 days of surgery or "postoperative radiotherapy deferred" otherwise. Factors associated with postoperative radiotherapy deferral were identified using multivariable logistic regression. Overall survival (OS) was compared using Kaplan-Meier analysis with log-rank tests and multivariable Cox regression. Statistical tests were 2-sided. Postoperative radiotherapy utilization and overall survival. Among 816 patients, 123 (15.1%) had postoperative radiotherapy deferred, and 693 (84.9%) had postoperative radiotherapy upfront; 36.8% of 3-year-olds and 4.1% of 8-year-olds had postoperative radiotherapy deferred (P < .001). On multivariable logistic regression, variables associated with postoperative radiotherapy deferral were age (odds ratio [OR], 0.57 per year; 95% CI, 0.49-0.67 per year) and year of diagnosis (OR, 1.18 per year; 95% CI, 1.08-1.29 per year). On survival analysis, with median follow-up of 4.8 years, OS was improved for those receiving postoperative radiotherapy upfront vs

Impact of surgical care improvement project inf-9 on postoperative urinary tract infections: do exemptions interfere with quality patient care?

The Surgical Care Improvement Project (SCIP) Inf-9 guideline promotes removal of indwelling urinary catheters (IUCs) within 48 hours of surgery. To determine whether a correlation exists between SCIP Inf-9 compliance and postoperative urinary tract infection (UTI) rates and whether an association exists between UTI rates and SCIP Inf-9 exemption status. DESIGN Retrospective case control study. Southeastern academic medical center. American College of Surgeons National Surgical Quality Improvement Program (NSQIP) and SCIP Inf-9 compliance data were collected prospectively on randomly selected general and vascular surgery inpatients. Monthly UTI rates and SCIP Inf-9 compliance scores were tested for correlation. Complete NSQIP data for all the inpatients with postoperative UTIs were compared with a group of 100 random controls to determine whether an association exists between UTI rates and SCIP Inf-9 exemption status. Postoperative UTI. In 2459 patients reviewed, SCIP Inf-9 compliance increased over time, but this was not correlated with improved monthly UTI rates. Sixty-one of the 69 UTIs (88.4%) were compliant with SCIP Inf-9; however, 49 (71.0%) of these were considered exempt from the guideline and, therefore, the IUC was not removed within 48 hours of surgery. Retrospective review of 100 random controls showed a similar compliance rate (84.0%, P = .43) but a lower rate of exemption (23.5%, P < .001). The odds of developing a postoperative UTI were 8 times higher in patients deemed exempt from SCIP Inf-9 (odds ratio [OR], 7.99; 95% CI, 3.85-16.61). After controlling for differences between the 2 groups, the adjusted ORs slightly increased (OR, 8.34; 95% CI, 3.70-18.76). Most UTIs occurred in patients deemed exempt from SCIP Inf-9. Although compliance rates remain high, practices are not actually improving. Surgical Care Improvement Project Inf-9 guidelines should be modified with fewer exemptions to facilitate earlier removal of IUCs.

Peripheral nerve injuries often undergo surgical repair, but poor postoperative functional recovery is frequently observed. We describe four cases of traumatic nerve lesions in whom postoperative recovery was prevented by complications such as detachment of nerve sutures or neuroma growth. To the best of our knowledge no similar cases have been reported in literature so far. It is important an early diagnosis of such condition because it prevents recovery and delays re-intervention, which should be performed before complete muscle denervation and atrophy. Nerve ultrasound is a valuable tool in traumatic nerve injury and has proven to be useful in postoperative follow-up, especially in diagnosing surgical complications such as detachment of nerve direct sutures.

Transthoracic esophagectomy using 3-field lymphadenectomy (TTE-3FL) for esophageal cancer is one of the most aggressive gastrointestinal surgeries. Early enteral nutrition (EN) for TTE-3FL patients is useful and valid for early recovery; however, EN using a fat-containing formula risks inducing chyle leak. In the present study, we retrospectively examined esophageal cancer patients treated byTTE-3FL and administered postoperative EN to elucidate the validity of lowering the fat levels in elemental formulas to prevent postoperative chyle leak and improve postoperative recovery. A total of 74 patients who received TTE-3FL for esophageal cancer were retrospectively examined. Patients were classified into two groups according to the type of postoperative EN: Group LF patients received a low-fat elemental formula, and Group F patients received a standard fat-containing polymeric formula. The following clinical factors were compared between the groups: EN start day, maximum EN calories administered, duration of respirator use, length of ICU stay, incidence of postoperative infectious complications, use of parenteral nutrition (PN), and incidence of postoperative chyle leak. Patients in Group LF were started on EN significantly earlier after surgery and they consumed significantly higher maximum EN calories compared to Group F patients (P < 0.01). Duration of respirator use and length of ICU stay were also significantly shorter, and TPN was used significantly less in Group LF compared to Group F (P < 0.05). Postoperative chyle leak was observed in six patients in total (8.1%); five patients in Group F and one patient in Group LF, although there was no significant difference in frequency of chyle leak per patient between Group LF and Group F. Early EN using low-fat elemental formula after esophagectomy with three-field lymphadenectomy was safe and valid for postoperative recovery and potentially useful in preventing chyle leak.

To determine whether opioids during the first 24 postoperative hours were significantly altered when receiving intravenous (IV) acetaminophen during that time compared with those receiving placebo (normal saline). One hundred forty patients undergoing any type of craniotomy were randomly assigned to receive either 1 g of IV acetaminophen or placebo upon surgical closure, and every 6 hours thereafter, up to 18 hours postoperatively. Analgesic requirements for the first 24 postoperative hours were recorded. Time to rescue medications in the postanesthesia care unit (PACU)/intensive care unit (ICU), amount of rescue medication, ICU and hospital lengths of stay, number of successful neurological examinations, sedation, delirium, satisfaction, and visual analog scale pain scores were also recorded. Compared with the placebo group, more patients in the IV acetaminophen group (10/66 [15.2%] vs. 4/65 [6.2%] in the placebo group) did not require opioids within the first 24 postoperative hours, but this did not reach significance (odds ratio, -9.0%, 95% confidence interval -20.5% to 1.8%; P = 0.166). Both groups had similar times to rescue medications, amounts of rescue medications, ICU and hospital lengths of stay, numbers of successful neurological examinations, sedation, delirium, satisfaction scores, visual analog scale pain scores, and temperatures within the first 24 postoperative hours. The opioid requirements within the first 24 postoperative hours were similar in the placebo and acetaminophen groups. This study is informative for the design and planning of future studies investigating the management of postoperative pain in patients undergoing craniotomies. Copyright © 2017 Elsevier Inc.

Postpancreatectomy hemorrhage (PPH) is an uncommon but serious complication of Whipple surgery. To evaluate the radiologic features associated with late PPH at the first postoperative follow up CT, before bleeding. To evaluate the radiological features associated with late PPH at the first follow-up CT, two radiologists retrospectively reviewed the initial postoperative follow-up CT images of 151 patients, who had undergone Whipple surgery. Twenty patients showed PPH due to vascular problem or anastomotic ulcer. The research compared CT and clinical findings of 20 patients with late PPH and 131 patients without late PPH, including presence of suggestive feature of pancreatic fistula (presence of air at fluid along pancreaticojejunostomy [PJ]), abscess (fluid collection with an enhancing rim or gas), fluid along hepaticojejunostomy or PJ, the density of ascites, and the size of visible gastroduodenal artery (GDA) stump. CT findings including pancreatic fistula, abscess, and large GDA stump were associated with PPH on univariate analysis ( p ≤ 0.009). On multivariate analysis, radiological features suggestive of a pancreatic fistula, abscess, and a GDA stump > 4.45 mm were associated with PPH ( p ≤ 0.031). Early postoperative CT findings including GDA stump size larger than 4.45 mm, fluid collection with an enhancing rim or gas, and air at fluid along PJ, could predict late PPH.

General anesthesia has been widely used in pediatric dentistry in recent years. However, there remain concerns about potential postoperative dental morbidity. The goal of this study was to identify the frequency of postoperative dental morbidity and factors associated with such morbidity in children. From March 2012 to February 2013, physically and mentally healthy children receiving dental treatment under general anesthesia at the Department of Pediatric Dentistry of the Chang Gung Memorial Hospital in Taiwan were recruited. This was a prospective and observational study with different time evaluations based on structured questionnaires and interviews. Information on the patient demographics, anesthesia and dental treatment performed, and postoperative dental morbidity was collected and analyzed. Correlations between the study variables and postoperative morbidity were analyzed based on the Pearson's chi-square test. Correlations between the study variables and the scale of postoperative dental pain were analyzed using the Mann-Whitney U test. Fifty-six pediatric patients participated in this study, with an average age of 3.34 ± 1.66 years (ranging from 1 to 8 years). Eighty-two percent of study participants reported postoperative dental pain, and 23% experienced postoperative dental bleeding. Both dental pain and bleeding subsided 3 days after the surgery. Dental pain was significantly associated with the total number of teeth treated, while dental bleeding, with the presence of teeth extracted. Patients' gender, age, preoperative dental pain, ASA classification, anesthesia time, and duration of the operation were not associated with postoperative dental morbidity. Dental pain was a more common postoperative dental morbidity than bleeding. The periods when parents reported more pain in their children were the day of the operation (immediately after the procedure) followed by 1 day and 3 days after the treatment.

To explore postoperative pain management experiences among school-aged children. Ineffective postoperative pain management among children has been commonly reported. School-aged children are able to evaluate how their pain is managed and what their preferred strategies are. Most studies in pain management have adopted quantitative methods and have overlooked children's pain management experiences. This is a qualitative study using face-to-face interviews. Data were collected from 15 school-aged children admitted to a tertiary hospital in Singapore by in-depth interviews conducted between November 2010 and January 2011. Data were analysed by thematic analysis. Five themes were identified: children's self-directed actions to relieve their postoperative pain (e.g. using cognitive-behavioural methods of distraction and imagery, physical method of positioning, sleeping and drinking, seeking other people's help by informing parents and crying and using pain medications); children's perceptions of actions parents take for their postoperative pain relief (assessing pain, administering pain medications, using various cognitive-behavioural, physical methods and emotional support strategies, assisting in activities and alerting health professionals); children's perception of actions nurses take for their postoperative pain relief (administering medication, using cognitive-behavioural methods, emotional support strategies and helping with activities of daily living) and suggestions for parents (using distraction and presence) and nurses (administering medications, distraction and positioning) for their postoperative pain relief improvement. This study contributed to the existing knowledge about children's postoperative pain management based on their own experiences. Children, their parents and nurses used various strategies, including pain medication and non-pharmacological methods, especially distraction, for children's postoperative pain relief.

Prolonged paralytic ileus occurring in hepatectomized patients may induce hyperammonemia or bacterial translocation, which injures the remnant liver function and sometimes causes post-resection liver failure. We examined the effectiveness of the herbal medicine, Dai-kenchu-to (DKT), on postoperative serum ammonia levels in patients with liver resection and compared it with lactulose. Patients with liver resection were divided into three groups. Lactulose group (n=31), 16g of lactulose was administered orally three times a day from the first postoperative day. DKT group (n=27), 5g of DKT was administered in the same fashion. Control group (n=26), neither lactulose nor DKT was administered. In all three groups, 16g of lactulose was administered three times a day for three days preoperatively. There was no significant difference among the groups in age, gender and preoperative hepatic functional values, such as ICG-R15 or galactose tolerance test. There was also no difference in parenchymal hepatic resection rate, operative time and amount of intraoperative bleeding volume. Postoperative serum ammonia levels were significantly lower in the DKT group than control and lactulose groups. Instances of delayed flatulence and occurrence of diarrhea were also fewer in the DKT group. DKT may become a more effective and safe agent than lactulose in postoperative management of liver resection.

While prevalent in everyday life, smartphones are also finding increasing use as a medical care adjunct. The use of smartphone technology as a postoperative cosmetic surgery adjunct for care has received little attention in the literature. The purpose of this effort was to assess the potential efficacy of a smartphone-based cosmetic surgery early postoperative follow-up program. Specifically, could smartphone photography provided by the patient to the plastic surgeon in the first few days after surgery allay patient's concerns, improve the postoperative experience and, possibly, detect early complications? From August 2015 to March 2016 a smartphone-based postoperative protocol was established for patients undergoing cosmetic procedures. At the time of discharge, the plastic surgeon sent a text to the patient with instructions for the patient to forward a postoperative photograph of the operated area within 48 to 72 hours. The plastic surgeon then made a return call/text that same day to review the patient's progress. A postoperative questionnaire evaluated the patients' postoperative experience and satisfaction with the program. A total of 57 patients were included in the study. Fifty-two patients responded to the survey. A total of 50 (96.2%) patients reported that the process improved the quality of their postoperative experience. The protocol allowed to detect early complications in 3 cases. The physician was able to address and treat the complications the following day prior to the scheduled clinic follow up. The smartphone can be effectively utilized by the surgeon to both enhance the patient's postoperative experience and alert the surgeon to early postoperative problems. 4. © 2017 The American Society for Aesthetic Plastic Surgery, Inc.

Cesarean delivery is one of the most common surgical procedures performed by obstetricians. Infectious morbidity after cesarean delivery can have a tremendous impact on the postpartum woman's return to normal function and her ability to care for her baby. Despite the widespread use of prophylactic antibiotics, postoperative infectious morbidity still complicates cesarean deliveries. To determine if cleansing the vagina with an antiseptic solution before a cesarean delivery decreases the risk of maternal infectious morbidities, including endometritis and wound complications. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (21 July 2014). We included randomized and quasi-randomized trials assessing the impact of vaginal cleansing immediately before cesarean delivery with any type of antiseptic solution versus a placebo solution/standard of care on post-cesarean infectious morbidity. We independently assessed eligibility and quality of the studies. Five trials randomizing 1946 women (1766 analyzed) evaluated the effects of vaginal cleansing (all with povidone-iodine) on post-cesarean infectious morbidity. The risk of bias was generally low, with the quality of most of the studies being high. Vaginal preparation immediately before cesarean delivery significantly reduced the incidence of post-cesarean endometritis from 7.2% in control groups to 3.6% in vaginal cleansing groups (average risk ratio (RR) 0.39, 95% confidence interval (CI) 0.16 to 0.97, five trials, 1766 women). The risk reduction was particularly strong for women with ruptured membranes (1.4% in the vaginal cleansing group versus 15.4% in the control group; RR 0.13, 95% CI 0.02 to 0.66, two trials, 148 women). No other outcomes realized statistically significant differences between the vaginal cleansing and control groups. No adverse effects were reported with the povidone-iodine vaginal cleansing.The quality of the evidence using GRADE was low for post-cesarean endometritis

Low serum albumin (SA) is a prognostic factor for poor outcome after cardiac surgery. The aim of this study was to estimate the association between pre-operative SA, early post-operative SA and postoperative myocardial injury. This single center cohort study included adult patients undergoing cardiac surgery during 4 consecutive years. Postoperative myocardial damage was defined by calculating the area under the curve (AUC) of troponin (Tn) values during the first 72 h after surgery and its association with SA analyzed using linear regression and with multivariable linear regression to account for patient related and procedural confounders. The association between SA and the secondary outcomes (peri-operative myocardial infarction [PMI], requiring ventilation >24 h, rhythm disturbances, 30-day mortality) was studied using (multivariable) log binomial regression analysis. In total 2757 patients were included. The mean pre-operative SA was 29 ± 13 g/l and the mean post-operative SA was 26 ± 6 g/l. Post-operative SA levels (on average 26 min after surgery) were inversely associated with postoperative myocardial damage in both univariable analysis (regression coefficient - 0.019, 95%CI -0.022/-0.015, p < 0.005) and after adjustment for patient related and surgical confounders (regression coefficient - 0.014 [95% CI -0.020/-0.008], p < 0.0005). Post-operative albumin levels were significantly correlated with the amount of postoperative myocardial damage in patients undergoing cardiac surgery independent of typical confounders.

To assess postoperative pain in endodontic therapy and its association with clinical factors such as gender, age, tooth type, pulpal diagnosis, and preoperative pain, length of obturation and sealer extrusion. Cross-Sectional study. Dental section of the Aga khan university hospital, Karachi, Pakistan from January to December 2009. One hundred and forty patients (140) requiring endodontic therapy for molar and premolar teeth were included in this study. Local Anesthesia (2% Lidocain with 1:80,000 Epinephrine) was administered. The tooth was isolated with rubber dam. Access cavity was prepared with the help of round carbide No. 2 bur. Canal preparation was completed using crown-down technique. Access was sealed with sterile dry cotton pallet and restored temporarily with double layer of Glass ionomer cement and Cavit. After one week patients were recalled and access was re-opened, obturation was done using cold lateral condensation technique. Ca(OH)(2) based sealer was used. Postoperative radiographs were taken. Patients were recalled after 24 hours and postobturation pain was recorded using Visual analogue scale (VAS).Data was obtained on a structured Performa. χ(2) test was used for statistical analysis. Pain was present in 42.9% of patients. Females more frequently experienced pain (65%) than males (35%). Preoperative pain was found to be significantly associated with postoperative pain (p value < 0.001). Obturation length was not found to be significantly associated with postoperative pain (p value 1.0). Sealer extrusion was not found to be significantly associated with postoperative (P value 0.547).

The effect of hospital organizational characteristics on postoperative complications.

Knight, Margaret

2013-12-01

To determine if there is a relationship between the risk of postoperative complications and the nonclinical hospital characteristics of bed size, ownership structure, relative urbanicity, regional location, teaching status, and area income status. This study involved a secondary analysis of 2006 administrative hospital data from a number of U.S. states. This data, gathered annually by the Agency for Healthcare Research and Quality (AHRQ) via the National Inpatient Sample (NIS) Healthcare Utilization Project (HCUP), was analyzed using probit regressions to measure the effects of several nonclinical hospital categories on seven diagnostic groupings. The study model included postoperative complications as well as additional potentially confounding variables. The results showed mixed outcomes for each of the hospital characteristic groupings. Subdividing these groupings to correspond with the HCUP data analysis allowed a greater understanding of how hospital characteristics' may affect postoperative outcomes. Nonclinical hospital characteristics do affect the various postoperative complications, but they do so inconsistently.

Tricuspid regurgitation (TR) is common in patients with heart failure undergoing left ventricular assist device (LVAD) implantation. Whether the TR should be surgically managed at the time of LVAD surgery is controversial. We searched SCOPUS, Web of Science, Ovid EMBASE, and Ovid MEDLINE (through May 10, 2014) for randomized controlled trials and observational studies comparing postoperative outcomes in patients treated with LVAD with concomitant tricuspid valve surgery (TVS) compared with LVAD alone. Six observational studies including 3,249 patients compared outcomes following LVAD + TVS versus LVAD. Four studies were single-center and most did not adjust for potential confounders. Addition of TVS prolonged cardiopulmonary bypass times by an average of 31 minutes (three studies, 95% CI 20-42). There was no difference in need for right ventricular assist device (six studies, HR 1.42, 95% CI 0.54-3.76), acute renal failure (four studies, HR 1.07, 95% CI 0.55-2.10), or early mortality (six studies, HR 1.28, 95% CI 0.78-2.08) in patients treated with LVAD + TVS versus LVAD alone. TVS prolongs cardiopulmonary bypass times, but available data demonstrate no significant association with early postoperative outcomes. However, differences in baseline risk of patients treated with TVS versus not limit our ability to draw conclusions.

Diabetes insipidus (DI) after endoscopic transsphenoidal surgery (ETSS) can lead to increased morbidity, longer hospital stays, and increased medication requirements. Predicting which patients are at high risk for developing DI can help direct services to ensure adequate care and follow-up. The objective of this study was to review our institution's experience with ETSS and determine which clinical/laboratory variables are associated with DI in this patient population. The authors wanted to see if there was an easily determined single value that would help predict which patients develop DI. This represents the largest North American series of this type. We retrospectively reviewed the charts of patients who had undergone ETSS for resection of sellar and parasellar pathology between 2006 and 2011. We examined patient and tumor characteristics and their relationship to postoperative DI. Out of 172 endoscopic transsphenoidal surgeries, there were 15 cases of transient DI (8.7%) and 14 cases of permanent DI (8.1%). Statistically significant predictors of postoperative DI (p < 0.05) included tumor volume and histopathology (Rathke's cleft cyst and craniopharyngioma). Significant indicators of development of DI were postoperative serum sodium, preoperative to postoperative change in sodium level, and urine output prior to administration of 1-deamino-8-D-arginine vasopressin. An increase in serum sodium of ≥2.5 mmol/L is a positive marker of development of DI with 80% specificity, and a postoperative serum sodium of ≥145 mmol/L is a positive indicator with 98% specificity. Identifying perioperative risk factors and objective indicators of DI after ETSS will help physicians care for patients postoperatively. In this large series, we demonstrated that there were multiple perioperative risk factors for the development of DI. These findings, which are consistent with other reports from microscopic surgical series, will help identify patients at risk for diabetes insipidus

Postoperative-treatment following open incisional hernia repair: A survey and a review of literature.

Incisional hernias of the abdominal wall are frequent complication after laparotomy (9-20%). Open incisional hernia repair with sublay mesh placement (SMP) on the posterior rectus sheath is described as being a sufficient method for repairing incisional hernia. In order to ensure wound healing and to therefore prevent recurrence, carrying an abdominal binder (AB) or a pressure dressing (PD) and physical rest for a certain time is the common postoperative recommendation, though the evidence for post-operative treatment is low. Hence, we conducted a survey to reveal the different recommendations given by surgical departments (SD). We conducted a survey among 65 German SDs of the XXX Hospital Group. The SDs were interviewed about the number of open incisional hernia repair with SMP in the time frame of 2013-2014, the known recurrence rate (RR), their recommended prescription of the AB/PD and the time of physical rest. The head physicians of 48 surgical departments answered the questionnaire. The survey revealed 42 different recommendations of postoperative-treatment. The majority of the SDs advices 4 weeks (20,5%) of physical rest and no prescription of the AB (29,5%). No correlation between the known RR and the duration of physical rest was detected. No head physician's prescribes a PD. Due to our findings we assume that a short period of physical rest is a considerable postoperative treatment following an open incisional hernia repair with SMP. By reducing the individual incapacity for work and immobility this would have a social-economic impact. The use of a PD may prevent seroma formation. Further investigations with randomized clinical trials are mandatory to support our hypothesis. Copyright © 2018 IJS Publishing Group Ltd. Published by Elsevier Ltd. All rights reserved.

To evaluate the relationship between cataract density and the deviation from the predicted refraction. Department of Ophthalmology, Nara Medical University, Kashihara, Japan. Axial length (AL) was measured in eyes with mainly nuclear cataract using partial coherence interferometry (IOLMaster). The postoperative AL was measured in pseudophakic mode. The AL difference was calculated by subtracting the postoperative AL from the preoperative AL. Cataract density was measured with the pupil dilated using anterior segment Scheimpflug imaging (EAS-1000). The predicted postoperative refraction was calculated using the SRK/T formula. The subjective refraction 3 months postoperatively was also measured. The mean absolute prediction error (MAE) (mean of absolute difference between predicted postoperative refraction and spherical equivalent of postoperative subjective refraction) was calculated. The relationship between the MAE and cataract density, age, preoperative visual acuity, anterior chamber depth, corneal radius of curvature, and AL difference was evaluated using multiple regression analysis. In the 96 eyes evaluated, the MAE was correlated with cataract density (r = 0.37, P = .001) and the AL difference (r = 0.34, P = .003) but not with the other parameters. The AL difference was correlated with cataract density (r = 0.53, P<.0001). The postoperative refractive outcome was affected by cataract density. This should be taken into consideration in eyes with a higher density cataract. (c) 2010 ASCRS and ESCRS. Published by Elsevier Inc. All rights reserved.

2009-06-01

The results of the surgical treatment of 82 patients with postoperative abdominal hernias were analysed. All of the patients underwent surgery with polypropylene endoprosthesis. The choice of a hernioplasty method depended on relative volume of postoperative hernia. Middle-sized hernias were indications for reconstructive surgery (complete adaptation of muscular and aponeurotic layers was maintained). The large and gigantic hernias were indications for correcting surgery (specified diastasis of muscular and aponeurotic layers was maintained). In case of lacking of peritoneum (30 patients) greater omentum was used for isolation of the net from intestinal loops. It is concluded that greater omentum provides good extraperitonisation of transplant from intestinal loop and prevents complications due to contact of net with abdominal organs. Postoperative complications mainly were local and seen in 29% cases. There were no lethal outcomes.

Music and the reduction of post-operative pain.

PubMed

Dunn, Kelly

The prevention and treatment of post-operative pain, and the promotion of comfort are the challenges facing practitioners working in the recovery room setting. Surgical pain produces autonomic, psychological, immunological and behavioural responses that can delay or inhibit normal healing. Nurses spend more time with patients experiencing pain than any other healthcare professional. Therefore, they are in an ideal position to consider other pain-relieving strategies to complement the analgesics currently used. The studies reviewed cannot prove that music is effective in reducing post-operative pain, because the research methodology in the majority is poor. Patients, experience of listening to music post-operatively was positive, aiding distraction and increasing comfort. This shows the difference between inconsistent results for the objective measures of pain and what the patient is reporting.

Effective pain management is an essential component in the perioperative care of surgical patients. However, postoperative pain after maxillofacial fracture repair and its optimal therapy has not been described in detail. In a prospective cohort study, 95 adults rated their pain on the first postoperative day after maxillofacial fracture repair using the questionnaire of the Quality Improvement in Postoperative Pain Management (QUIPS) project. Quality Improvement in Postoperative Pain Management allowed for a standardized assessment of patients' characteristics and pain-related parameters. Overall, the mean maximal pain and pain on activity (numeric rating scales) were significantly higher in patients with mandibular fractures than in patients with midface fractures (P = 0.002 and P = 0.045, respectively). In patients with mandibular fractures, a longer duration of surgery was significantly associated with higher satisfaction with pain intensity (P = 0.015), but was more frequently associated with postoperative vomiting (P = 0.023). A shorter duration of surgery and an absence of preoperative pain counseling in these patients were significantly correlated to desire for more pain medication (P = 0.049 and P = 0.004, respectively). Patients with mandibular fractures that received opioids in the recovery room had significantly higher strain-related pain (P = 0.017). In patients with midface fractures, a longer duration of surgery showed significantly higher levels of decreased mobility (P = 0.003). Patients receiving midazolam for premedication had significantly less minimal pain (P = 0.021). Patients with mandibular fractures seem to have more postoperative pain than patients with midface fractures. Monitoring of postsurgical pain and a procedure-specific pain-treatment protocol should be performed in clinical routine.

Recently, the use of smartphones to deliver health-related content has experienced rapid growth, with more than 165,000 mobile health (mHealth) apps currently available in the digital marketplace. With 3 out of 4 Canadians currently owning a smartphone, mHealth apps offer opportunities to deliver accessible health-related knowledge and support. Many individuals experience pain after surgery, which can negatively impact their health-related quality of life, including sleep, emotional, and social functioning. Smartphone apps that provide remote real-time monitoring and symptom management have the potential to improve self-management skills in patients experiencing postoperative pain. Increased confidence and practice of self-management skills could contribute to decreased postoperative pain and reduce risk of developing persistent pain. Published reviews of general pain self-management apps demonstrate a lack of evidence-based content, theoretical grounding, and health care professional involvement. However, no review to date has focused on the app marketplace specific for individuals with postoperative pain. The aim of this study was to characterize and critically appraise the content and functionality of commercially available postoperative pain self-management apps. An electronic search and extraction was conducted between December 2016 and March 2017 of the official Canadian app stores for the three major smartphone operating systems (iPhone operating system [iOS], Android, and Windows). Stores were searched separately using predetermined search terms. Two authors screened apps based on information provided in the public app description. Metadata from all included apps were abstracted into a standard spreadsheet. Two authors verified the data with reference to the apps and downloaded apps themselves. The content and functionality of each app as it pertained to postoperative pain self-management was rated. A total of 10 apps met the inclusion criteria. All

Background Preoperative anaemia is associated with adverse outcomes after surgery but outcomes after liver surgery specifically are not well established. We aimed to analyze the incidence of and effects of preoperative anemia on morbidity and mortality in patients undergoing liver resection. Methods All elective hepatectomies performed for the period 2005–2012 recorded in the American College of Surgeons' National Surgical Quality Improvement Program (ACS-NSQIP) database were evaluated. We obtained anonymized data for 30-day mortality and major morbidity (one or more major complication), demographics, and preoperative and perioperative risk factors. We used multivariable logistic regression models to assess the adjusted effect of anemia, which was defined as (hematocrit <39% in men, <36% in women), on postoperative outcomes. Results We obtained data for 12,987 patients, of whom 4260 (32.8%) had preoperative anemia. Patients with preoperative anemia experienced higher postoperative major morbidity and mortality rates compared to those without anemia. After adjustment for predefined variables, preoperative anemia was an independent risk factor for postoperative major morbidity (adjusted OR 1.21, 1.09–1.33). After adjustment, there was no significant difference in postoperative mortality for patients with or without preoperative anemia (adjusted OR 0.88, 0.66–1.16). Conclusion Preoperative anemia is independently associated with an increased risk of major morbidity in patients undergoing hepatectomy. Therefore, it is crucial to readdress preoperative blood management in anemic patients prior to hepatectomy. PMID:27017165

To examine the role of ethnicity and language in parent report of children's postoperative behavioral recovery. To compare incidence of new onset negative behavior change in English- and Spanish-speaking White and Hispanic children following outpatient surgery. Postoperative behavioral change in children is common; however, it is unknown whether cultural variables including ethnicity and language may influence parent report of children's behavioral recovery. Participants included 288 parents (English-speaking White, English-speaking Hispanic, Spanish-speaking Hispanic parents) of children undergoing outpatient elective surgery. Parents completed the post-hospitalization behavior questionnaire (PHBQ) and parents' postoperative pain measure (PPPM) on postoperative days one, three, and seven at home. Most parents (83%) reported onset of new negative behavioral change in children postoperatively. Generalized estimating equations revealed significant group differences in overall behavior change [Wald χ(2)(12) = 375.69, P < 0.0001] after controlling for demographic and socioeconomic differences. At all three postoperative days, Spanish-speaking Hispanic (SSH) parents reported lower negative behavioral changes in their children compared to English-speaking White (ESW) parents (day 1: P < 0.01; day 3: P < 0.001; day 7: P < 0.10). On postoperative days one and three, SSH parents also reported lower total PHBQ scores than English-speaking Hispanic (ESH) parents [day 1: χ(2)(1) = 6.72, P = 0.01; day 3: χ(2)(1) = 7.98, P = 0.005]. The present study provides evidence that parent report of children's postoperative behavioral recovery may be influenced by cultural variables, such as ethnicity and language. The present results contribute to a growing body of evidence that highlights the need for culturally sensitive assessment and care of families in the medical setting. The findings may reflect differences in cultural values such as stoicism; however, future studies would

Abstract Introduction: Pain management after surgery continues to be suboptimal; there are several reasons including lack of translation of results from basic science studies and scientific clinical evidence into clinical praxis. Objectives: This review presents and discusses basic science findings and scientific evidence generated within the last 2 decades in the field of acute postoperative pain. Methods: In the first part of the review, we give an overview about studies that have investigated the pathophysiology of postoperative pain by using rodent models of incisional pain up to July 2016. The second focus of the review lies on treatment recommendations based on guidelines and clinical evidence, eg, by using the fourth edition of the “Acute Pain Management: Scientific Evidence” of the Australian and New Zealand College of Anaesthetists and Faculty of Pain Medicine. Results: Preclinical studies in rodent models characterized responses of primary afferent nociceptors and dorsal horn neurons as one neural basis for pain behavior including resting pain, hyperalgesia, movement-evoked pain or anxiety- and depression-like behaviors after surgery. Furthermore, the role of certain receptors, mediators, and neurotransmitters involved in peripheral and central sensitization after incision were identified; many of these are very specific, relate to some modalities only, and are unique for incisional pain. Future treatment should focus on these targets to develop therapeutic agents that are effective for the treatment of postoperative pain as well as have few side effects. Furthermore, basic science findings translate well into results from clinical studies. Scientific evidence is able to point towards useful (and less useful) elements of multimodal analgesia able to reduce opioid consumption, improve pain management, and enhance recovery. Conclusion: Understanding basic mechanisms of postoperative pain to identify effective treatment strategies may improve patients

Paralytic ileus after laparoscopic-assisted surgery often occurs. We investigated whether daikenchuto (DKT), a traditional Japanese herbal medicine, improves intestinal motility in patients undergoing laparoscopic-assisted colectomy for colon cancer. Fifty-four patients who underwent colectomy at Iwate Medical University Hospital between October 2010 and March 2012 were randomized to either the DKT group (7.5 g/day, p.o.) or the control group (lactobacillus preparation, 3g/day, p.o.). Primary endpoints included time to first flatus, bowel movement, and tolerance of diet after extubation. Secondary endpoints were WBC count, C-reactive protein (CRP) level, length of hospital stay, and postoperative ileus. Colonic transit time was measured using radiopaque markers and abdominal radiographs. Fifty-one patients (DKT, 26 vs. control, 25) were included in the per-protocol analysis. The DKT group had significantly faster time until first flatus (67.5 +/- 13.6h vs. 77.9 +/- 11.8h, P < 0.01) and bowel movement (82.9 +/- 17.8h vs. 99.5 +/- 18.9h, P < 0.01) and colonic transit time (91.9 +/- 19.8h vs. 115.2 +/- 12.8 h, P < 0.05). There were no significant intergroup differences in secondary endpoints and adverse events. DKT accelerates colonic motility in patients undergoing laparoscopic-assisted colectomy for colon cancer.

Aspergillus fungi can cause serious infections, including intra-abdominal infection, particularly in patients with compromised immune system. Described in the present report is case of 46-year-old female patient who had undergone laparoscopic cholecystectomy (LC) at another healthcare facility. In early postoperative period, she had increasing complaints of swelling, nausea, and vomiting. On postoperative 19th day, she was referred to our clinic with diagnosis of acute abdomen. Surgery was performed with suspected possibility of bile leakage. However, pathological examination of soft, yellow-green mass found in subhepatic space determined it was fungus ball caused by fungi of the genus Aspergillus. Patient was diagnosed postoperative intra-abdominal aspergillosis (IAA).

To assess the impact of a short hypnotic session on postoperative anxiety and pain in major orthopaedic surgery. Despite specific information given before a scheduled paediatric surgery, perioperative anxiety can become important. Randomised Clinical Study. The study is an open single-centre randomised clinical study comparing a "control" group versus a "hypnosis" group receiving a short hypnosis pre-induction session as additional experimental analgesic procedure. The primary endpoint was the postoperative anxiety, blindly assessed using a visual analogue scale. The study involved 120 children (age 10-18 years). The results showed no difference between control group versus hypnosis group. Twenty-four hours after surgery (Day+1), the patient's anxiety score was not different between control and hypnosis groups (median [Q1-Q3]: 1 [0; 3] vs. 0 [0; 3], respectively, p = .17). Each group experienced a significant decrease in anxiety level between the day before surgery (Day-1) and the day after surgery (Day+1) (median ([Q1-Q3]) difference of the anxiety score: 2 [4; 0] and 2 [4; 0], respectively, p < .0001 in each group). The postoperative pain scores were low and not different between groups (median [Q1-Q3]: 2 [0; 3] in control group vs. 3 [1; 3] in hypnosis group, p = .57). This randomised study on a short hypnosis session performed in the operating room prior to a major surgery showed no difference in postoperative anxiety and pain levels. The decrease in anxiety and pain levels may be due to the addition of nurse pre-operative interviews and optimisation in communication in the operating room. As postoperative anxiety level was low in both control and hypnosis groups, nurse pre-operative interviews and nurse training in hypnosis may contribute to the optimisation of global management and decrease the postoperative anxiety level. © 2017 John Wiley & Sons Ltd.

Patients with rectus free flap harvest extending below the arcuate line are predisposed to postoperative hernia formation. As such, many authors have advocated the use of closure adjuncts to increase the integrity of the closure and prevent hernia or abdominal wall bulging. Busy level 1 public trauma center in metropolitan Fort Worth, Texas Following harvest of the rectus free flap, 48 patients underwent primary closure; 24 of these patients had defects extending below the arcuate line. Forty patients were closed with an acellular dermal graft; 22 of these patients had defects extending below the arcuate line. Postoperative hernia formation and local infection rate were examined in a minimum follow-up period of 1 year. Regardless of closure method, no hernias were observed in the postoperative period. Using an unpaired t test and an alpha value of 0.05, there was no statistically significant difference in the infection rate between the two groups. Following rectus abdominis myocutaneous free flap harvest, the use of an acellular dermal graft in abdominal wall closure may not be of any further advantage in the prevention of hernia. Retrospective (Level III).

This study was performed to assess surgical outcomes when externally irrigated slow-speed surgical handpieces (30,000 rpm) were compared to externally irrigated high-speed handpieces (90,000 rpm) in the removal of impacted lower third molar teeth. One hundred patients with bilater ally impacted third molar s were enrolled in the study; 53 remained to completion. Each patient served as his/her own control. The experimental side was treated using a 30,000 rpm electric rotary drill incorporating irrigation, while the control side was treated using the same drill system, but with a 90,000 rpm handpiece. Drill speeds used were alternated between the right and left sides of patients to avoid bias introduced by the dominant hand of the surgeon. Patients were blinded to drill speed, and were asked to complete a standardized pain/swelling questionnaire for seven days immediately following surgery. Data was analyzed to determine differences in pain, swelling, and complications in relation to the drill type used. No statistically significant differences were found in degree of pain, swelling, or complications when the slower drill was compared to the high-speed instrument. The study suggests that there is no difference in postoperative outcome when impacted third molar teeth are removed with either slow- or high-speed instrumentation, and that the choice of the drill type should be determined solely by the preference of the operator.

The objective of this study was to determine the prevalence, severity, and duration of postoperative pain in children undergoing general anesthesia for dentistry. This prospective cross-sectional study included 33 American Society of Anesthesiology (ASA) Class I and II children 4–6 years old requiring multiple dental procedures, including at least 1 extraction, and/or pulpectomy, and/or pulpotomy of the primary dentition. Exclusion criteria were children who were developmentally delayed, cognitively impaired, born prematurely, taking psychotropic medications, or recorded baseline pain or analgesic use. The primary outcome of pain was measured by parents using the validated Faces Pain Scale-Revised (FPS-R) and Parents' Postoperative Pain Measure (PPPM) during the first 72 hours at home. The results showed that moderate-to-severe postoperative pain, defined as FPS-R ≥ 6, was reported in 48.5% of children. The prevalence of moderate-to-severe pain was 29.0% by FPS-R and 40.0% by PPPM at 2 hours after discharge. Pain subsided over 3 days. Postoperative pain scores increased significantly from baseline (P < .001, Wilcoxon matched pairs signed rank test). Moderately good correlation between the 2 pain measures existed 2 and 12 hours from discharge (Spearman rhos correlation coefficients of 0.604 and 0.603, P < .005). In conclusion, children do experience moderate-to-severe pain postoperatively. Although parents successfully used pain scales, they infrequently administered analgesics. PMID:26650492

Tramadol was found to be more effective than dexamethasone in post-operative pain control, with long-lasting relief of pain. This study aimed to compare the effects of pre-operative local injections of tramadol and dexamethasone on post-operative pain, nausea and vomiting in patients who underwent tonsillectomy. Sixty patients between 3-13 years of age who were planned for tonsillectomy were included in the study. Patients were divided into three groups. Group 1 was the control group. Patients in Group 2 received 0.3 mg/kg Dexamethasone and Group 3 received 0.1 mg/kg Tramadol injection to the peritonsillary space just before the operation. Patients were evaluated for nausea, vomiting, and pain. When the control and the dexamethasone groups were compared; there were statistically significant differences in pain scores at post-operative 15 and 30 min, whereas there was no statistically significant difference in pain scores at other hours. When the control and tramadol groups were compared, there was a statistically significant difference in pain scores at all intervals. When tramadol and dexamethasone groups were compared, there was no statistically significant difference in pain scores at post-operative 15 and 30 min, 1 and 2 h, whereas there was a statistically significant difference in pain scores at post-operative 6 and 24 h.

Results of an interprofessional formulary initiative to decrease postoperative prescribing of i.v. acetaminophen are reported. After a medical center added i.v. acetaminophen to its formulary, increased prescribing of the i.v. formulation and a 3-fold price increase resulted in monthly spending of more than $40,000, prompting an organizationwide effort to curtail that cost while maintaining effective pain management. The surgery, anesthesia, and pharmacy departments applied the Institute for Healthcare Improvement's Model for Improvement to implement (1) pharmacist-led enforcement of prescribing restrictions, (2) retrospective evaluation of i.v. acetaminophen's impact on rates of opioid-related adverse effects, (3) restriction of prescribing of the drug to 1 postoperative dose on select patient care services, and (4) guideline-driven pain management according to an enhanced recovery after surgery (ERAS) protocol. Monitored metrics included the monthly i.v. acetaminophen prescribing rate, the proportion of i.v. acetaminophen orders requiring pharmacist intervention to enforce prescribing restrictions, and prescribing rates for select adjunctive analgesics. Within a year of project implementation, the mean monthly i.v. acetaminophen prescribing rate decreased by 83% from baseline to about 6 doses per 100 patient-days, with a decline in the monthly drug cost to about $4,000. Documented pharmacist interventions increased 2.7-fold, and use of oral acetaminophen, ketorolac, and gabapentin in ERAS areas increased by 18% overall. An interprofessional initiative at a large medical center reduced postoperative use of i.v. acetaminophen by more than 80% and yielded over $400,000 in annual cost savings.

In Chiari I patients, postoperative pain and discomfort frequently slow the transition back to the home setting. We sought to determine the effect of standardized ketamine infusion protocols on hospital length of stay (LOS). This retrospective cohort study reviewed 100 consecutive adult patients undergoing Chiari I decompression. Fifty-nine patients were placed on a 2-3 mg/hr ketamine drip until postoperative day 1. This group was compared with a group who received 2-3 mg/hr of ketamine until postoperative day 2 (19 patients) and patients who did not receive ketamine at all (22 patients). Clinical characteristics, opioid use, LOS, and relative hospitalization costs were assessed. All narcotic amounts were converted into milligram equivalents of morphine. LOS of the short-ketamine group was 46.5 hours when compared with the long-ketamine group (66.8 hours) and no-ketamine group (56.9 hours). There was a statistically significant difference when comparing the short-ketamine group with the long-ketamine group and no-ketamine group together (P < 0.001), as well as when compared individually (P = 0.001 and 0.004). The mean cost of hospitalization was 20% less when a short-ketamine protocol was used (P < 0.001). Mean morphine milligram equivalents used postoperatively were 148 mg in the short-ketamine group, 196 mg in the long-ketamine group, and 187 mg in the no-ketamine group (P = 0.65). No adverse events from ketamine were noted. Ketamine at subanesthetic levels may be an effective tool to facilitate early return home postoperatively and may significantly reduce medical costs.

To evaluate the effect of cataract density on the postoperative refractive outcome. For 59 nuclear cataract eyes, the axial length was preoperatively measured by the IOL Master (Zeiss, Germany) and ultrasound (US; UD-6000, Tomey, Japan) and the cataract density by EAS-1000 (Nidek, Japan). The prediction error was used as evaluation of the accuracy of ocular biometry. There were significant differences between IOL Master and US in the mean error (0.24 +/- 0.63 vs. 0.69 +/- 0.64 dpt, p < 0.001) and the mean absolute error (0.57 +/- 0.36 vs. 0.79 +/- 0.53 dpt, p < 0.001). The cataract density was significantly correlated with the prediction error with IOL Master (r = 0.24, p = 0.03) and US (r = 0.29, p = 0.01). Measurements with the IOL Master are slightly affected by the cataract density due to the refractive index change, but its accuracy is less affected than US. (c) 2007 S. Karger AG, Basel.
