Psychosocial outcomes following emergency laparotomy (POLO) study: a study protocol for a multicentre mixed-methods prospective cohort study assessing the psycho-social outcomes following emergency laparotomy in adults.

INTRODUCTION: Morbidity from an emergency laparotomy (EmLap) is difficult to define and poorly understood. Morbidity is a holistic concept, reliant upon an interplay of bio-psychosocial outcomes that evolve long after discharge. To date, no previous study has explored the psychosocial outcomes following EmLap as a collective, nor their change over time. This study aims to describe the holistic morbidity following EmLap within the first year following surgery. METHODS AND ANALYSIS: This is a multicentre, mixed-methods prospective 12-month cohort study with two participant populations: patient participants and family caregivers (FCGs). A target of 160 adult patients who undergo EmLap and can give informed consent will be included in the patient participant group. Patient participants will be asked to complete three patient surveys, incorporating validated patient-reported outcome measures (PROMs) to assess bio-psychosocial outcomes (EuroQol five-dimension five-level (EQ5D-5L), Gastrointestinal Quality Life Index-36, Patient Health Questionnaire-9, Generalised Anxiety Disorder 7, International Trauma Questionnaire, Caregiver Interaction Scale and Fatigue Severity Scale) in the 12 months following surgery. A subgroup of 15 patient participants will be asked to take part in two semistructured interviews at 6 and 12 months. A target of 15 associated family caregivers will be included in the FCG group. FCGs will be asked to take part in a semi-structured interview at 6 months to assess the EmLap impact on the wider support network. The primary outcome will be a change in quality of life (EQ5D-5L) at 12 months. Secondary outcomes will be changes in bio-psychosocial status at 3 and 12 months. Qualitative analysis will allow contextualisation of PROMS and further explore themes of EmLap morbidity. It is anticipated that the results of this study will help inform and develop standards of aftercare for future EmLap patients. ETHICS AND DISSEMINATION: This study has received ethical approval (Wales REC7;12/WA/0297) and will be undertaken in accordance with the principles of Good Clinical Practice. We intend to disseminate study results in peer-reviewed journals and medical conferences, as well as a lay report to study participants. TRIAL REGISTRATION NUMBER: Clinical Trials.gov NCT05281627.

Deleterious synergistic effects of distress and surgery on cancer metastasis: Abolishment through an integrated perioperative immune-stimulating stress-inflammatory-reducing intervention.

The perioperative period holds disproportionate impact on long-term cancer outcomes. Nevertheless, perioperative interventions to improve long-term cancer outcomes are not clinical routines, including perioperative stress-reducing or immune-stimulating approaches. Here, mimicking the clinical setting of pre-operative distress, followed by surgery, we examined the separate and combined effects of these events on the efficacy of pre-operative immune stimulation in rats and mice, and on post-operative resistance to tumor metastasis of the syngeneic mammary adenocarcinoma MADB106 in F344 rats and the CT26 colon carcinoma in Balb/C mice. The novel immune stimulating agents, GLA-SE or CpG-C (TLR-4 and TLR-9 agonists, respectively), were employed pre-operatively. Sixteen hours of pre-operative behavioral stressors (i) lowered CpG-C induced plasma IL-12 levels, and reduced resistance to MADB106 and CT-26 experimental metastases, and (ii) worsened the deleterious effects of laparotomy on metastasis in both tumor models. In rats, these effects of pre-operative stress were further studied and successfully abolished by the glucocorticoid receptor antagonist RU-486. Additionally, in vitro studies indicated the dampening effect of corticosterone on immune stimulation. Last, we tested a perioperative integrated intervention in the context of pre-operative stress and laparotomy, based on (i) antagonizing the impact of glucocorticoids before surgery, (ii) activating anti-metastatic immunity perioperatively, and (iii) blocking excessive operative and post-operative adrenergic and prostanoid responses. This integrated intervention successfully and completely abolished the deleterious effects of stress and of surgery on post-operative resistance to experimental metastasis. Such and similar integrated approaches can be studied clinically in cancer patients.

Impact of self-inflicted injury on nontherapeutic laparotomy in patients with abdominal stab wounds.

INTRODUCTION: Because Japan has high suicide rates and low violent crime rates, it is likely that most abdominal stab wounds (ASWs) in Japan are self-inflicted. Although physical examination is one of the most important factors in surgical decision making, such evaluations can be difficult in patients with self-inflicted ASWs due to patient agitation and uncooperative behavior. Therefore, the self-inflicted nature of an injury may strongly affect clinical practice, particularly in Japan, but its influence remains uncertain. We hypothesized that the rates of exploratory laparotomy and nontherapeutic laparotomy (NTL) would be higher in self-inflicted patients. METHODS: We reviewed ASW patients from 2004 to 2014 in the Japan Trauma Data Bank. The rates of exploratory laparotomy and NTL were compared between self-inflicted and non-self-inflicted ASWs. RESULTS: Of the 1705 eligible patients, 1302 patients (76.4%) had self-inflicted ASWs, and 403 patients (23.6%) had non-self-inflicted ASWs. Self-inflicted patients had a significantly higher rate of psychiatric history, but lower injury severity. The in-hospital mortality rate was similar between the two groups (4.5% vs. 5.2%, p = 0.576). Self-inflicted patients had significantly higher rates of exploratory laparotomy and NTL (69.1% vs. 56.7%, p < 0.001, 22.5% vs. 13.6%, p = 0.03, respectively). Self-inflicted patients were also associated with significantly longer hospital stays (10.0 [5.0-21.0] vs. 9.0 [4.0-18.0] days, P = 0.045). In a multivariable analysis, self-inflicted patients were independently associated with exploratory laparotomy (odds ratio [OR], 2.05; 95% confidence interval [CI]: 1.55-2.72) and NTL (OR, 1.61; 95% CI: 1.01-2.56). CONCLUSION: ASWs in Japan were predominantly self-inflicted. The clinical patterns of self-inflicted ASWs had some unique features. Patients with self-inflicted ASWs had higher rates of laparotomy and NTL. Further studies are needed to develop a useful protocol specific to self-inflicted ASWs.

Single-Institution Propensity-Matched Study to Evaluate the Psychological Effect of Minimally Invasive Interval Debulking Surgery Versus Standard Laparotomic Treatment: From Body to Mind and Back.

STUDY OBJECTIVE: To further investigate the psycho-oncologic effect of minimally invasive surgery comparing patients submitted to minimally invasive interval debulking surgery (MI-IDS) with a balanced population treated by standard laparotomy (L-IDS). DESIGN: Single-institution propensity-matched study (Canadian Task Force classification II-2). SETTING: Division of Gynecologic Oncology, "Policlinico A. Gemelli" Foundation, Rome, Italy. PATIENTS: The investigational arm included 30 patients with advanced ovarian cancer treated with MI-IDS, whereas the control arm included a consecutive series of 30 patients with advanced ovarian cancer submitted to L-IDS. For every patient preoperative data were collected to assess the response to neoadjuvant chemotherapy. Perioperative data were also recorded. INTERVENTIONS: A General Well-Being Schedule (GWBS) and a clinical assessment of body uneasiness, the Body Uneasiness Test, were administered by a psycho-oncologist immediately before IDS and within 30 days after surgery to evaluate the psychological burden in both groups. MEASUREMENT AND MAIN RESULTS: Both groups were matched as closely as possible. No statistical differences were registered in terms of surgical procedures and residual tumor. A significantly longer median operative time in patients was counterbalanced by more favorable estimated blood loss and median length of stay and time to chemotherapy. No statistically significant differences were registered in terms of postoperative complications. Starting from a substantially homogenous psychological condition, psychometric evaluation underlined statistically significant differences in favor of MI-IDS. The mean GWBS score was 64.17 ± 11.77 in patients and 54.15 ± 14.76 in control subjects, with a statistically significant difference between the 2 groups (p = .004). CONCLUSION: MI-IDS seems to play an important role in the quality of life and oncologic outcomes. Even if presented data testified a further evolutionary step in oncologic patient care, more experience with larger groups of patients is desirable to deeply investigate and assess our results.

An evaluation of quality of life in women with endometriosis who underwent primary surgery: a 6-month follow up in Sabah Women & Children Hospital, Sabah, Malaysia.

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

An Experience of an Individual With a Chronic Wound in an Open Abdomen: A Grounded Theory.

The open abdomen (OA) surgical technique has become an option for treating complex abdominal injuries; however, complications leading to late closure conditions might arise. In these cases the wound must be left open, which greatly impacts the patient's life. OBJECTIVE: The author aims to describe the experiences of individuals with a chronic OA wound. METHODS: Qualitative design using grounded theory was utilized. This study was carried out with a group of 28 adults who were treated with OA technique and whose wound had remained open for more than a month in duration and only received outpatient wound care. Data were collected through open interviews and examined under continuous comparison. The average age of the respondents was 45 years, and their wound, treated with OA due to severe abdominal infection, remained open between 2 months and 8 years. RESULTS: An emergent theory was developed to describe how people facing this experience undergo a process of 4 stages: 1) finding an OA wound upon waking, 2) feeling desperate about the healing process and the limitations involved, 3) regaining control of their life, and 4) taking advantage of their second chance at life with an OA wound. CONCLUSION: This study provides insight for nurses and other health care professionals into the experiences of patients with a chronic OA wound and proposes an emerging theory based on the conceptualization of these experiences.

[The Psychometric Properties of the Abdominal Surgery Impact Scale]. / Übersetzung und Testung der Abdominal Surgery Impact Scale.

Background: Assessment of quality of life immediately after abdominal surgery is critical; however, potent tools that provide timely information about patient health are required in order to assess and improve postoperative quality of care. Interestingly, such assessment scales for early postoperative quality of life do not exist in German. The aim of this pilot study was to translate the English version of the "Abdominal Surgery Impact Scale" (ASIS) into German and to empirically test the German version. Methods: After the standardized translation, 30 German-speaking patients who had undergone visceral surgery (laparotomy) were recruited at the ward of the Bern University Hospital Visceral Surgery and Medicine. The internal consistency of the translated instrument (ASIS-D) was assessed on the third postoperative day; reliability, retest-reliability and construct validity were also assessed on the fifth postoperative day. Results: ASIS-D faithfully represented the content of the original version. Cronbach's α overall was 0.85 and for the 6 subscales 0.45-0.88. The overall score of retest-reliability was 0.57** and the construct validity was confirmed. Conclusion: The ASIS-D was shown to be reliable and valid even if other investigations are necessary. It provides specific insights into special postoperative symptoms such as wound pain and postoperative quality of sleep. After further tests, it might be suitable not only for capturing the short-term postal-surgical quality of life, but possibly also for evaluating nursing interventions.

Impact of Preoperative Environmental Enrichment on Prevention of Development of Cognitive Impairment following Abdominal Surgery in a Rat Model.

BACKGROUND: Sustained neuroinflammation may contribute to the pathogenesis of postoperative cognitive dysfunction (POCD). Here, the authors evaluated the preventive effect of preoperative environmental enrichment (PEE) on the development of neuroinflammation and concomitant POCD in a rat abdominal surgery model. METHODS: Young and aged rats were assigned to one of four groups using a 2 × 2 experimental design: PEE versus sedentary condition for 14 days, by abdominal surgery versus anesthesia alone (n = 8 in each group). After a 7-day postsurgical recovery period, cognitive function was assessed using a novel object recognition test, followed by measurement of hippocampal levels of proinflammatory cytokines. Under identical conditions, microglia were isolated from the hippocampus for assessment of cytokine response to lipopolysaccharide. RESULTS: In the sedentary group, aged, but not young, rats receiving surgery showed memory deficits (novel object preference during testing phase of 54.6 ± 7.8% vs. 76.9 ± 11.3% in nonsurgery group, P < 0.05) and increased hippocampal levels of cytokines compared with nonsurgical rats. PEE had no effects on novel object preference in nonsurgery animals (78.6 ± 10.7%), whereas it attenuated surgery-induced impairment of novel object preference (70.9 ± 15.0%, P < 0.05 vs. sedentary/surgery group) as well as increase of cytokine levels in hippocampus. Furthermore, upon ex vivo stimulation with lipopolysaccharide, cytokines release from hippocampal microglia isolated from aged rats before intervention was significantly higher in comparison with young rats. PEE resulted in reduction of these age-related microglial phenotypic changes. CONCLUSIONS: PEE could prevent the development of neuroinflammation and related POCD in aged rats by reversion of a proinflammatory phenotype of hippocampal microglia.

Management of a patient with autism following ingestion of a foreign body.

Patients with autism often find admission to hospital an anxious time. Awareness of the condition, a speedy diagnosis and flexibility in adapting treatment plans will facilitate early discharge and return to their familiar environment. We describe a patient with severe autism who presented with an acute abdomen secondary to ingestion of a foreign body which required laparotomy. Communication directly to medical staff was greatly limited due to severe autism and close liaison with family members was essential in interpreting scant clinical signs. At the time of surgery a rubber bottle teat was found causing transection of small bowel due to erosion of the foreign body. The postoperative course was fraught with challenges and ensuring side room nursing care with family members present throughout his admission minimised postoperative stress and confusion. We recommend awareness of management strategies for patients with autism to ensure rapid recovery and early discharge home.

[The quality of life after cholecystectomy].

The quality of life (QOL) of three groups of patients who had undergone the routine cholecystectomy (RCE), laparoscopic cholecystectomy (LCE), or cholecystectomy using the minilaparatomy approach (MCE). QOL was assessed using the standard SF-36 questionnaire and on selected criteria. The postoperative complications rate after any version of cholecystectomy did not exceed the average rate in other studies. Patients with a history of LCE and MCE, returned to their normal social and intellectual activity faster; they reported higher perception and judgment on the state of their health and well-being, which in turn suggests the higher quality of life. Patients after RCE reported worse results due to a longer recovery period.

Staged abdominal repairs reduce long-term quality of life.

INTRODUCTION: Damage control surgery increasingly requires serial operations and a staged abdominal repair (STAR) for ultimate abdominal closure. The effects of multiple operations on quality of life are unknown. We hypothesized that this population of patients had a lower quality of life than the general U.S. population. METHODS: Patients requiring STAR for general surgical and trauma diagnoses during a 5-year period from January 2002 to December 2006 were identified from the operative database of a single institution. Demographic, illness, and injury information were obtained from record review. Survivors were 3-7 years from their hospitalization for STAR when they were contacted and the SF-12v2 was administered by phone. The physical (PCS) and mental component (MCS) scores were calculated and compared to US population norms and a population of trauma patients. The non-STAR trauma population completed the SF-12v2 six months after injury. RESULTS: A total of 27 patients with a mean age of 46.5 years (SD = 15.9) participated in the survey. The participants were interviewed a median of 4.7 years after injury. The mechanism of injury included 8 (29.6%) general surgical causes including 4 perforated viscus, 3 intra-abdominal infections, and 1 wound dehiscence from a urological procedure. The remaining 19 (70.4%) were trauma-related, including 13 blunt and 6 penetrating injuries. Patients who had undergone a STAR procedure reported lower levels of physical quality of life [z = -15.42, p<0.001] and mental quality of life [z = -6.79, p<0.001] compared to population norms for healthy adults. Also, STAR patients reported lower physical [z = -2.22, p<0.05] and mental [z = -2.59, p<0.05] quality of life as the non-STAR trauma group. DISCUSSION: The number of patients undergoing STAR for a variety of reasons is increasing. Measurements of quality of life of STAR patients show that quality of life is reduced compared to a healthy U.S. adult population and to non-STAR trauma patients. CONCLUSIONS: The significant impact of severe abdominal injuries continues to affect the physical and mental health of patients years later. Injuries of this type are associated with lower quality of life than those observed in patients experiencing non-STAR trauma.

Effects of listening to music on pain intensity and pain distress after surgery: an intervention.

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

[Level of depression in women undergoing gynecologic surgery]. / Analiza poziomu depresji u kobiet leczonych operacyjnie na oddziale ginekologii.

STUDY OBJECTIVE: To determine the level of depression in women during the early post-operative period. MATERIAL AND METHOD: 220 women treated surgically for various gynecologic conditions were enrolled. The study was done between day 4-6 after surgery using Beck's Depression Inventory (BDI). The results were analyzed statistically. RESULTS: It was found that the mean level of depression on the BDI scale in the study group of women was 12.24 +/- 8.73. The mean level of depression in patients who underwent surgery using the vaginal route was significantly greater (p = 0.003) than in patients after laparoscopy and patients after laparotomy. CONCLUSIONS: The mean level of depression in the study group approached values found in depression. Patients after surgery using the vaginal route demonstrated higher levels of depression than patients after laparoscopy. Age, education, source of subsistence, and number of children had an impact on the level of depression in the study group. Marital status and place of residence were without effect on the level of depression in the patients.

A comparison of nurses' perceptions of elective laparoscopic or elective open colorectal resections.

The purpose of this study was to develop an instrument to measure the perceived benefits nurses observe in the recovery of patients who have undergone elective laparoscopic colorectal resections vs. traditional open elective colorectal resections. Secondly, to determine if there are perceived differences in the intensity of nursing required to care for these patients. A twenty-three-point questionnaire was developed and distributed to 23 colorectal nurses working in a single tertiary referral hospital. There was an 83.6% response rate. The findings demonstrate that the participants believe there are significantly better outcomes for the laparoscopic patients in the postoperative period. These benefits include more rapid resumption of independence, decreased pain and fewer complications. The nurses also perceived less time and effort was required when caring for these patients.

Ghost Ileostomy with or without abdominal parietal split.

BACKGROUND: In patients who undergo low anterior rectal resection, the fashioning of a covering stoma (CS) is still controversial. In fact, a covering stoma (ileostomy or colostomy) is worsened by major complications related to the procedure, longer recovery time, necessity of a re-intervention under general anesthesia for stoma closure and poorer quality of life. The advantage of Ghost Ileostomy (GI) is that an ileostomy can be performed only when there is clinical evidence of anastomotic leakage, without performing further interventions with related complications when anastomotic leak is absent and therefore the procedure is not necessary. Moreover, in case of anastomotic dehiscence and necessity of delayed stoma opening, mortality and morbidity in patients with GI are comparable with the ones that occur in patients which had a classic covering stoma. On the other hand, is simple to think about the possible economic saving: avoiding an admission for performing the closure of the ileostomy, with all the costs connected (OR, hospitalization, post-operative period, treatment of possible complications) represents a huge saving for the hospital management and also raise the quality of life of the patients. METHODS: In this study we prospectively analyzed 20 patients who underwent anterior extra-peritoneal rectum resection for rectal carcinoma with TME and fashioning of GI realized with or without abdominal parietal split. RESULTS: In the group of patients that received a GI without split laparotomy mortality was absent and in one case an anastomotic leak occurred. In the group of patients in which GI with split laparotomy was fashioned, one death occurred and there were one case of infection and one respiratory complication. Clinical follow-up was 12 months. CONCLUSIONS: The use of different techniques for fashioning a GI do not present significant differences when they are performed by expert surgeons, but further evidence is needed with more randomized trials, in order to have more data supporting the clinical observation.

Characterization of Fyn signaling on the age-dependent immuno-modulation on traumatic rats.

Traumatic stress is well characterized to develop immuno-depression in our previous report. Here, we provide evidence that adult and aged rats showed similar decrease in lymphocyte proliferation and natural killer (NK) cell activity. However, compared with beginning recovering from traumatic stress after 3 day and fully recovered by 7 day in adult rats, aged rats begin the recovery phage later than 3 day and do not fully recovered by 7 day. In parallel, Fyn expression in cerebral cortex was augmented with the highest level at 3 day of trauma in both age groups of rats, although aged rats exhibited lower level than the younger cohorts. Immune consequences were consequently modified by intracerebroventricular (i.c.v.) injection of Fyn antibody or recombinant adenovirus expressing active Fyn. Finally, the increase in Fyn expression was converged on ERK1/2 (extracellular signal regulated kinase 1/2) activation. Taken together, the data indicated that immunological processes in response to traumatic stress was age dependent, Fyn-ERK1/2 signal pathway was required to convey the recovery signals.

Circumumbilical pyloromyotomy in the era of minimally invasive surgery.

BACKGROUND/PURPOSE: No studies have investigated the cosmetic outcome of current approaches to pyloromyotomy in infants with hypertrophic pyloric stenosis. The purpose of this study was to evaluate the final appearance of the scar in patients undergoing circumumbilical pyloromyotomy. METHODS: During a 16-year period, 86 infants underwent circumumbilical pyloromyotomy at our institution. A detailed questionnaire was created to document the family members' perceptions of the esthetic appearance of the scar. Data were collected by telephone interview and at clinic visit. In addition, cosmesis was assessed by 5 staff members who scored blindly the esthetic outcome of the scars with comparative photographs, using a categorical scale. RESULTS: Fifty-seven families were tracked by telephone contact. In the family questionnaire, 100% of families reported an excellent or good scar. Of these, forty-one (72%) were available for cosmetic assessment. Follow-up ranged between 5 months and 15 years (mean, 6 years). The panel members ranked the scar, on average, as excellent or good for 90% of the patients. No assessor stated that a scar was unacceptable. Intra- and interobserver agreement was 0.72 and 0.78, respectively. CONCLUSIONS: Overall satisfaction with the cosmetic outcome of circumumbilical pyloromyotomy is very high.

Health related quality of life six months following surgical treatment for secondary peritonitis--using the EQ-5D questionnaire.

BACKGROUND: To compare health related quality of life (HR-QoL) in patients surgically treated for secondary peritonitis to that of a healthy population. And to prospectively identify factors associated with poorer (lower) HR-QoL. DESIGN: A prospective cohort of secondary peritonitis patients was mailed the EQ-5D and EQ-VAS 6-months following initial laparotomy. SETTING: Multicenter study in two academic and seven regional teaching hospitals. PATIENTS: 130 of the 155 eligible patients (84%) responded to the HR-QoL questionnaires. RESULTS: HR-QoL was significantly worse on all dimensions in peritonitis patients than in a healthy reference population. Peritonitis characteristics at initial presentation were not associated with HR-QoL at six months. A more complicated course of the disease leading to longer hospitalization times and patients with an enterostomy had a negative impact on the mobility (p = 0.02), self-care (p < 0.001) and daily activities: (p = 0.01). In a multivariate analysis for the EQ-VAS every doubling of hospital stay decreases the EQ-VAS by 3.8 points (p = 0.015). Morbidity during the six-month follow-up was not found to be predictive for the EQ-5D or EQ-VAS. CONCLUSION: Six months following initial surgery, patients with secondary peritonitis report more problems in HR-QoL than a healthy reference population. Unfavorable disease characteristics at initial presentation were not predictive for poorer HR-QoL, but a more complicated course of the disease was most predictive of HR-QoL at 6 months.

Assessment of patient functional status after surgery.

BACKGROUND: Improvement in day-to-day functioning is a valued outcome of surgical intervention. A new functional status assessment instrument, the Activities Assessment Scale (AAS), was designed for a randomized clinical trial evaluating laparoscopic versus open hernia repair procedures. STUDY DESIGN: The study data set included 2,164 patients at baseline and 1,562 patients at 3-month followup. Only male patients were enrolled in the trial. The psychometric characteristics of the AAS were examined in statistical analyses of cross-sectional and longitudinal data from the trial. Correlational analyses, factor analyses, and t-tests were used to evaluate scale performance. RESULTS: We found that the AAS was a reliable measure (Cronbach's Coefficient Alpha =0.85) in the patient population studied. Factor analyses identified three subscales (sedentary activities; ambulatory activities; work and exercise activities). Construct validity was demonstrated by a correlation of 0.65 between the AAS and the physical functioning (PF) dimension of the SF-36 (p < 0.001); comparisons between clinical subgroups further confirmed its validity (p < 0.001). Patients reporting improvement on the physical functioning dimension after surgery showed an effect size of 1.20 for preoperative-postoperative change in their AAS scores. CONCLUSIONS: The AAS has been demonstrated to be a reliable, valid, and clinically responsive instrument that can be used to evaluate patient functioning after hernia surgery. It is easy to administer and requires less than 5 minutes of patient time to complete. This measurement system may prove useful in assessing surgical outcomes in both research and office practice settings.

Effects of laparotomy on spontaneous exploratory activity and conditioned operant responding in the rat: a model for postoperative pain.

BACKGROUND: Treatment of postsurgical pain is a major use of analgesics, particularly after abdominal surgery. Analgesics display a number of limiting side effects, including sedation, cognitive impairment, and ileus. Although several postoperative rodent models have been developed, these models do not address these concerns. METHODS: A model is presented in the rat in which a subcostal incision is performed, penetrating into the peritoneal cavity. The behavioral effects of this surgical procedure are assessed using exploratory locomotor activity and conditioned operant responding. The effects of morphine and ketorolac were assessed in both behavioral paradigms. RESULTS: Laparotomy decreased ambulation and rearing by approximately 50% 24 h after surgery, and stereotypy (small confined movements) was affected to a lesser degree. The effects of laparotomy on conditioned operant responding were more complex. Total number of sucrose pellets earned was decreased for 2-3 days after laparotomy; however, the amount of time required was increased for up to 2 weeks. Morphine reversed the effects of surgery on ambulation and stereotypy but not rearing, and the dose-effect curve for morphine was shifted to the left by 5 mg/kg ketorolac. Ketorolac produced significant improvement in operant responding after laparotomy, and coadministration of ineffective doses of morphine and ketorolac produced a positive response. CONCLUSION: The current model is consistent with behavioral aspects of postoperative pain seen clinically. The effects of morphine and ketorolac alone and in combination were consistent with the reported analgesic efficacy and occurrence of side effects found with these agents clinically.
