Preoperative screening and prehabilitation strategies prior to ileocolic resection in patients with Crohn's disease are not incorporated in routine care

PURPOSE

Recently, recommendations on perioperative care have been published to optimize postoperative outcomes in preoperative patients with inflammatory bowel disease. This study evaluated the current use of preoperative screening and prehabilitation strategies (PS) prior to elective ileocolic resection (ICR) in patients with Crohn's disease (CD).

METHODS

Patients with CD who underwent an elective ICR were identified from a Dutch prospective cohort study. Primary endpoint was to evaluate to what extent IBD-relevant PS were applied in patients with CD prior to ICR according to the current recommendations.

RESULTS

In total, 109 CD patients were included. Screening of nutritional status was performed in 56% of the patients and revealed malnutrition in 46% of these patients. Of the malnourished patients, 46% was referred to a dietitian. Active smoking and alcohol consumption were reported in 20% and 28%; none of these patients were referred for a cessation program. A preoperative anemia was diagnosed in 61%, and ferritin levels were assessed in 26% of these patients. Iron therapy was started in 25% of the patients with an iron deficiency anemia. Exposure to corticosteroids at time of ICR was reported in 29% and weaned off in 3%. Consultation of a dietitian, psychologist, and physiotherapist was reported in 36%, 7%, and 3%. Physical fitness was assessed in none of the patients.

CONCLUSION

PS are not routinely applied and not individually tailored in the preoperative setting prior to elective ICR in patients with CD. Prior to implementation, future research on the costs and effectiveness of PS on postoperative outcomes and quality of life is necessary.

The multi-societal European consensus on the terminology, diagnosis and management of patients with synchronous colorectal cancer and liver metastases: an E-AHPBA consensus in partnership with ESSO, ESCP, ESGAR, and CIRSE

BACKGROUND

Contemporary management of patients with synchronous colorectal cancer and liver metastases is complex. The aim of this project was to provide a practical framework for care of patients with synchronous colorectal cancer and liver metastases with a focus on terminology, diagnosis and management.

METHODS

This project was a multi-organisational, multidisciplinary consensus. The consensus group produced statements which focused on terminology, diagnosis and management. Statements were refined during an online Delphi process and those with 70% agreement or above were reviewed at a final meeting. Iterations of the report were shared by electronic mail to arrive at a final agreed document comprising twelve key statements.

RESULTS

Synchronous liver metastases are those detected at the time of presentation of the primary tumour. The term "early metachronous metastases" applies to those absent at presentation but detected within 12 months of diagnosis of the primary tumour with "late metachronous metastases" applied to those detected after 12 months. Disappearing metastases applies to lesions which are no longer detectable on MR scan after systemic chemotherapy. Guidance was provided on the recommended composition of tumour boards and clinical assessment in emergency and elective settings. The consensus focused on treatment pathways including systemic chemotherapy, synchronous surgery and the staged approach with either colorectal or liver-directed surgery as first step. Management of pulmonary metastases and the role of minimally invasive surgery was discussed.

CONCLUSIONS

The recommendations of this contemporary consensus provide information of practical value to clinicians managing patients with synchronous colorectal cancer and liver metastases.

Development and validation of a remote monitoring tool for assessment of mild, moderate, and severe infections in Inflammatory Bowel Disease

BACKGROUND

Immunomodulators and biologicals are cornerstones in the management of Inflammatory Bowel Disease (IBD), but are associated with increased risk of infections. Post-marketing surveillance registries are pivotal to assess this risk, yet mainly focus on severe infections. Data on the prevalence of mild and moderate infections are scarce. We developed and validated a remote monitoring tool for real-world assessment of infections in IBD patients.

METHODS

A 7-item Patient-Reported Infections Questionnaire (PRIQ) covering 15 infection categories was developed with a 3-month recall period. Infection severity was defined as mild (self-limiting or topical treatment), moderate (oral antibiotics, antivirals or antifungals) or severe (hospitalisation or IV treatment). Comprehensiveness and comprehensibility were ascertained through cognitive interviewing of 36 IBD outpatients. After implementation in telemedicine platform myIBDcoach, a prospective multicentre cohort study was performed between June 2020 and June 2021 in 584 patients to assess diagnostic accuracy. Events were cross-checked with GP and pharmacy data (gold standard). Agreement was evaluated using linear-weighted kappa with cluster-bootstrapping to account for within-patient level correlation.

RESULTS

Patient understanding was good and interviews did not result in reduction of PRIQ-items. During validation, 584 IBD patients (57.8% female, mean age 48.6 [SD: 14.8], disease duration 12.6 years [SD: 10.9]) completed 1386 periodic assessments, reporting 1626 events. Linear-weighted kappa for agreement between PRIQ and gold standard was 0.92 (95%CI 0.89-0.94). Sensitivity and specificity for infection (y/n) were 93.9% (95%CI 91.8-96.0) and 98.5% (95%CI 97.5-99.4).

CONCLUSIONS

The PRIQ is a valid and accurate remote monitoring tool to assess infections in IBD patients, providing means to personalise medicine based on adequate benefit-risk assessments.

Assessing the development status of intraoperative fluorescence imaging for anatomy visualisation, using the IDEAL framework

Objectives

Intraoperative fluorescence imaging is currently used in a variety of surgical fields for four main purposes: visualising anatomy, assessing tissue perfusion, identifying/localising cancer and mapping lymphatic systems. To establish evidence-based guidance for research and practice, understanding the state of research on fluorescence imaging in different surgical fields is needed. We evaluated the evidence on fluorescence imaging used to visualise anatomical structures using the IDEAL framework, a framework designed to describe the stages of innovation in surgery and other interventional procedures.

Design

IDEAL staging based on a thorough literature review.

Setting

All publications on intraoperative fluorescence imaging for visualising anatomical structures reported in PubMed through 2020 were identified for five surgical procedures: cholangiography, hepatic segmentation, lung segmentation, ureterography and parathyroid identification.

Main outcome measures

The IDEAL stage of research evidence was determined for each of the five procedures using a previously described approach.

Results

225 articles (8427 cases) were selected for analysis. Current status of research evidence on fluorescence imaging was rated IDEAL stage 2a for ureterography and lung segmentation, IDEAL 2b for hepatic segmentation and IDEAL stage 3 for cholangiography and parathyroid identification. Enhanced tissue identification rates using fluorescence imaging relative to conventional white-light imaging have been documented for all five procedures by comparative studies including randomised controlled trials for cholangiography and parathyroid identification. Advantages of anatomy visualisation with fluorescence imaging for improving short-term and long-term postoperative outcomes also were demonstrated, especially for hepatobiliary surgery and (para)thyroidectomy. No adverse reactions associated with fluorescent agents were reported.

Conclusions

Intraoperative fluorescence imaging can be used safely to enhance the identification of anatomical structures, which may lead to improved postoperative outcomes. Overviewing current research knowledge using the IDEAL framework aids in designing further studies to develop fluorescence imaging techniques into an essential intraoperative navigation tool in each surgical field.

Consensus Conference Statement on the General Use of Near-infrared Fluorescence Imaging and Indocyanine Green Guided Surgery: Results of a Modified Delphi Study

BACKGROUND

In recent decades, the use of near-infrared light and fluorescence-guidance during open and laparoscopic surgery has exponentially expanded across various clinical settings. However, tremendous variability exists in how it is performed.

OBJECTIVE

In this first published survey of international experts on fluorescence-guided surgery, we sought to identify areas of consensus and nonconsensus across 4 areas of practice: fundamentals; patient selection/preparation; technical aspects; and effectiveness and safety.

METHODS

A Delphi survey was conducted among 19 international experts in fluorescence-guided surgery attending a 1-day consensus meeting in Frankfurt, Germany on September 8th, 2019. Using mobile phones, experts were asked to anonymously vote over 2 rounds of voting, with 70% and 80% set as a priori thresholds for consensus and vote robustness, respectively.

RESULTS

Experts from 5 continents reached consensus on 41 of 44 statements, including strong consensus that near-infrared fluorescence-guided surgery is both effective and safe across a broad variety of clinical settings, including the localization of critical anatomical structures like vessels, detection of tumors and sentinel nodes, assessment of tissue perfusion and anastomotic leaks, delineation of segmented organs, and localization of parathyroid glands. Although the minimum and maximum safe effective dose of ICG were felt to be 1 to 2 mg and >10 mg, respectively, there was strong consensus that determining the optimum dose, concentration, route and timing of ICG administration should be an ongoing research focus.

CONCLUSIONS

Although fluorescence imaging was almost unanimously perceived to be both effective and safe across a broad range of clinical settings, considerable further research remains necessary to optimize its use.

Supervisors' transformational leadership style and residents' job crafting in surgical training: the residents' views

OBJECTIVES

This study aims to explore the effects of three supervisors' leadership styles (transformational, transactional, and laissez-faire) on residents' job crafting.

METHODS

Sequential explanatory mixed-methods. First, a purposive sample of residents rated the leadership style of their supervisors and their own job crafting on the Multifactor Leadership Questionnaire and the Dutch Job Crafting Scale. The effects were tested through linear mixed effects regression analysis. Thereafter we conducted semi-structured interviews with residents and conducted a thematic analysis.

RESULTS

A total of 116 residents participated. A transformational style had a positive effect on residents' job crafting (b = .19, t₍₁₁₂₎ =3.76, p=. 009), whereas the transactional and laissez-faire styles did not. This could be explained by the fact that residents felt a positive influence of the supervisors with such style on the atmosphere for training, on the job resources available to them, and on their modelling function for how to handle the demands of the environment.

CONCLUSIONS

A transformational style of the supervisor has a positive effect on residents' job crafting. Future research should explore the supervisors' perspective, as well as the effectiveness of leadership training for supervisors with a focus on resident outcomes, such as job crafting.

Fluorescence-based bowel anastomosis perfusion evaluation: results from the IHU-IRCAD-EAES EURO-FIGS registry

BACKGROUND

Anastomotic leakage (AL) is one of the dreaded complications following surgery in the digestive tract. Near-infrared fluorescence (NIRF) imaging is a means to intraoperatively visualize anastomotic perfusion, facilitating fluorescence image-guided surgery (FIGS) with the purpose to reduce the incidence of AL. The aim of this study was to analyze the current practices and results of NIRF imaging of the anastomosis in digestive tract surgery through the EURO-FIGS registry.

METHODS

Analysis of data prospectively collected by the registry members provided patient and procedural data along with the ICG dose, timing, and consequences of NIRF imaging. Among the included upper-GI, colorectal, and bariatric surgeries, subgroup analysis was performed to identify risk factors associated with complications.

RESULTS

A total of 1240 patients were included in the study. The included patients, 74.8% of whom were operated on for cancer, originated from 8 European countries and 30 hospitals. A total of 54 surgeons performed the procedures. In 83.8% of cases, a pre-anastomotic ICG dose was administered, and in 60.1% of cases, a post-anastomotic ICG dose was administered. A significant difference (p < 0.001) was found in the ICG dose given in the four pathology groups registered (range: 0.013-0.89 mg/kg) and a significant (p < 0.001) negative correlation was found between the ICG dose and BMI. In 27.3% of the procedures, the choice of the anastomotic level was guided by means of NIRF imaging which means that in these cases NIRF imaging changed the level of anastomosis which was first decided based on visual findings in conventional white light imaging. In 98.7% of the procedures, the use of ICG partly or strongly provided a sense of confidence about the anastomosis. A total of 133 complications occurred, without any statistical significance in the incidence of complications in the anastomoses, whether they were ICG-guided or not.

CONCLUSION

The EURO-FIGS registry provides an insight into the current clinical practice across Europe with respect to NIRF imaging of anastomotic perfusion during digestive tract surgery.

Learner involvement in the co-creation of teaching and learning: AMEE Guide No. 138

This AMEE guide aims to emphasize the value of active learner involvement in the design and development of education, referred to as co-creation, and provides practical tips for medical educators interested in implementing co-created educational initiatives at their own institutions. Starting with definitions of co-creation and related terms, we then describe its benefits and summarize the literature in medical and higher education to provide an appropriate context and a shared mental model for health professions educators across the world. Potential challenges and barriers to implementation of co-creation in practice are described in detail from the perspective of learners, teachers, and institutions. Challenges are linked to relevant principles of Self-Determination Theory, Positioning Theory and theory on Psychological Safety, to provide direction and fundamental reasons for implementation of co-creation. Finally, solutions to listed challenges and practical approaches to education design and implementation using co-creation are described in detail. These tips include strategies for supporting learners and teachers in the process, enhancing the collaboration between them, and ensuring appropriate support at the organizational level.

How Surgical Leaders Transform Their Residents to Craft Their Jobs: Surgeons' Perspective

BACKGROUND

Surgeons should transform their residents to take the lead in their jobs and optimize their working conditions, so-called job crafting. We investigated the actions undertaken by surgeons with a transformational leadership style to encourage residents' job crafting, about which there is at present a paucity of information.

METHODS

We performed a qualitative study based on principles of constructivist grounded theory. In-depth interviews were held with a purposive sample of surgeons who were perceived as transformational leaders by their residents. During data analysis (open, axial, and selective coding), we compared inductive codes with deductive codes drawn from the job demands-resources and transformational leadership theories to reach a consensus on the interpretation of data and identification of the main themes.

RESULTS

Sixteen surgeons participated. Surgeons undertook five actions that enhanced job crafting in residents. They: one) modeled positive behaviors of a good surgeon; two) used a stepwise individual approach toward autonomy; three) connected with the resident as a person; four) supported residents in handling complications and errors; and five) they coached the resident to deal with competing interests. These actions had four consequences for residents. They led to: one) more responsibilities in patient care; two) more constructive relationships in the workplace; three) less pressure from workload and surgical care duties; and four) less personal difficulties and errors in patient care.

CONCLUSIONS

The actions undertaken by surgeons with a transformational leadership style have a positive association with the residents' ability to craft their jobs. This knowledge has implications for surgeons' leadership development with a view to workplace education.

Discrete choice experiment on educating value-based healthcare

INTRODUCTION

Identifying costs and values in healthcare interventions as well as the ability to measure and consider costs relative to value for patients are pivotal in clinical decision-making and medical education. This study explores residents' preferences in educating value-based healthcare (VBHC) during postgraduate medical education. Exploring residents' preferences in VBHC education, in order to understand what shapes their choices, might contribute to improved medical residency education and healthcare as a whole.

METHODS

A discrete choice experiment (DCE) examined which conditions for educating VBHC are preferred by residents. DCE gives more insight into the trade-off's residents make when choosing alternatives, and which conditions for educating VBHC have the most influence on residents' preference.

RESULTS

This DCE shows that residents prefer knowledge on both medical practice as well as the process of care-to be educated by an expert on VBHC together with a clinician. They prefer limited protected time to conduct VBHC initiatives (thus while at work) and desire the inclusion of VBHC in formal educational plans.

CONCLUSION

When optimising graduate and postgraduate medical education curricula, these preferences should be considered to create necessary conditions for the facilitation and participation of residents in VBHC education and the set-up of VBHC initiatives.

ECCO Guidelines on Therapeutics in Crohn's Disease: Surgical Treatment

This article is the second in a series of two publications relating to the European Crohn's and Colitis Organisation [ECCO] evidence-based consensus on the management of Crohn's disease. The first article covers medical management; the present article addresses surgical management, including preoperative aspects and drug management before surgery. It also provides technical advice for a variety of common clinical situations. Both articles together represent the evidence-based recommendations of the ECCO for Crohn's disease and an update of previous guidelines.

The Struggle Is Real: How Residents Learn to Provide High-Value, Cost-Conscious Care

Phenomenon: Rising healthcare expenditures threaten the accessibility and affordability of healthcare systems. Research has demonstrated that teaching (junior) physicians to deliver high-value, cost-conscious care can be effective when learning is situated in a supportive environment. This study aims to offer insight into how residents learn to provide high-value, cost-conscious care in the workplace and how the postgraduate training environment influences this learning. Approach: Six homogeneous focus groups were held between August 2015 and July 2016 with 36 residents from six residency programs (dermatology, n = 5; elderly care, n = 8; family medicine, n = 5; internal medicine, n = 6; orthopedic surgery, n = 6; surgery, n = 6). An iterative grounded theory approach was used to analyze the qualitative data. Findings: Influential factors in learning of high-value, cost-conscious care delivery operated on three levels: individual resident, training program, and the workplace. On the individual level, we discerned three types of beliefs regarding HV3C. At the training program level, perceived determinants of learning included resident-supervisor interactions, involvement in decision-making over time, and exposure to variation in care delivery. At the workplace level, learning depended on the availability of professional healthcare expertise and the presence of institutional policy. Insights: Residents struggle to seize high-value, cost-conscious care learning opportunities in the workplace setting. Both residency training programs and workplaces can contribute to creating these learning opportunities. An important starting point is being aware of the different personal beliefs of residents and the approaches to high-value, cost-conscious care on the level of the training program and workplace.

Taking control: Is job crafting related to the intention to leave surgical training?

OBJECTIVE

The intention to leave surgical training, hereinafter referred as proxy of "attrition," is associated with poor well-being in the workplace. Attrition is suggested to diminish when residents possess job-crafting skills, that is, the ability to redefine their job in meaningful ways and maximize well-being at work by increasing structural and social resources and challenges and decreasing hindering demands. However, the evidence supporting this relationship is scant. This study sought to: 1) investigate to what extent residents possess job-crafting skills and compare residents' levels of job-crafting skills across years of residency training; 2) investigate the relationship between job crafting, well-being as measured by burnout and work-engagement rates, and the intention to leave; and 3) compare the levels of job-crafting skills and well-being between residents with and without serious intentions to leave.

METHODS

This cross sectional study was conducted in fifteen residency programs in Colombia. Surgical residents completed different questionnaires including the Dutch Job Crafting Scale (DJCS), MBI-Human Services Survey (MBI-HSS), Utrecht Work Engagement Scale (UWES-17) and an adapted version of the Nurse Turnover Intention Scale (NTIS). The objectives were addressed by independent analyses of variance (ANOVA), structural equation modeling techniques (SEM) and independent t-tests, respectively.

RESULTS

A total of 202 residents participated. Residents generally scored high on their job-crafting skills to increase structural and social resources as well as challenging demands, but were less positive about their skills to reduce hindering demands. No differences across years of training were found. Job crafting correlated positively with work-engagement, which was inversely related to the intention to leave. Conversely, job crafting correlated negatively with burnout, which bore a positive relationship to the intention to leave. Residents with serious intentions to leave exhibited lower levels of most job-crafting skills and work-engagement, compared to those without such intentions.

CONCLUSIONS

This study adds evidence that attrition is a process mediated by residents' well being at work, which can be molded by their job-crafting endeavors. Future research is needed to evaluate the effectiveness of interventions aimed at cultivating resident's job-crafting abilities in order to reduce attrition.

Use of Transcutaneous Oxygen Tension Before, During, and After Arterial Reconstructive Surgery

The diagnostic and predictive value of transcutaneous oxygen tension (tcPO2) measurements in patients undergoing lower extremity arterial recon structive surgery were evaluated. Foot tcPO2 was measured preoperatively in 114 patients, intraoperatively in 59 patients, and again seven days after surgery in 82 patients. Preoperative tcPO 2 values less than 30 mmHg were indicative of severe limb ischemia in 90% of patients with rest pain, impending gangrene, or ischemic ulcer. Fifteen minutes after revascularization, tcPO2 greater than 30 mmHg was predictive of a "good" result (determined clinically at one month) in 94% of patients, whereas values less than 30 mmHg predicted a "poor" result in 70% of patients. Measurements obtained seven days postoperatively exhibited an improved negative predictive tcPO2 value (85%) as compared with those ob tained intraoperatively. TCPO2 changes induced by oxygen inhalation were the most promising predictor of the outcome of surgery. TCPO2 was uniformly more reliable than hemodynamic tests (pulse volume recording and Doppler systolic pressure) when more severe disease was present and vice versa; their comple mentary nature suggests the two techniques can be used together to maximize noninvasive diagnostic value.

Assessment of Clinical Complete Response After Chemoradiation for Rectal Cancer with Digital Rectal Examination, Endoscopy, and MRI: Selection for Organ-Saving Treatment

Background

The response to chemoradiotherapy (CRT) for rectal cancer can be assessed by clinical examination, consisting of digital rectal examination (DRE) and endoscopy, and by MRI. A high accuracy is required to select complete response (CR) for organ-preserving treatment. The aim of this study was to evaluate the value of clinical examination (endoscopy with or without biopsy and DRE), T2W-MRI, and diffusion-weighted MRI (DWI) for the detection of CR after CRT.

Methods

This prospective cohort study in a university hospital recruited 50 patients who underwent clinical assessment (DRE, endoscopy with or without biopsy), T2W-MRI, and DWI at 6–8 weeks after CRT. Confidence levels were used to score the likelihood of CR. The reference standard was histopathology or recurrence-free interval of >12 months in cases of wait-and-see approaches. Diagnostic performance was calculated by area under the receiver operator characteristics curve, with corresponding sensitivities and specificities. Strategies were assessed and compared by use of likelihood ratios.

Results

Seventeen (34 %) of 50 patients had a CR. Areas under the curve were 0.88 (0.78–1.00) for clinical assessment and 0.79 (0.66–0.92) for T2W-MRI and DWI. Combining the modalities led to a posttest probability for predicting a CR of 98 %. Conversely, when all modalities indicated residual tumor, 15 % of patients still experienced CR.

Conclusions

Clinical assessment after CRT is the single most accurate modality for identification of CR after CRT. Addition of MRI with DWI further improves the diagnostic performance, and the combination can be recommended as the optimal strategy for a safe and accurate selection of CR after CRT.

The value of the 'buccal pad of fat' in the reconstruction of oral defects following removal of intraoral tumours--a clinical assessment

The buccal pad of fat (BPF) is an important structure found in the orofacial region of humans. It is larger in infants and gradually becomes smaller in adults. We present twenty seven (27) cases with an average age of 60 years, with a variety of pathological lesions in which we have used the BPF to reconstruct the defects following resection of tumours. Twenty (74%) patients were diagnosed with Squamous Cell Carcinma. The commonest surgical sites were the soft palate and maxilla (46%). A clinical analysis of the value of BPF in reconstruction was made by using assessment criteria, mouth opening, cosmesis, fistula formation, approved by the ethical committee of the Hospital. Our findings show that the BPF is an excellent pedicled graft for the reconstruction of defects up to 10x5.5x1.1 cm in size. The donor site had no morbidity in terms of fuctions including, mouth opening (normal), masticatory movement, deglution, motor / sensory loss and patients were unaffected cosmetically (no temporal hollwing). There was no abnormal finding e.g. fistula, Frey's syndrome, speech and movement of the soft palate was unaffected. Salivary function was not affected (parotid duct). Speech outcomes were normal. We used a pre-surgery constructed blow--down soft or a preformed acrylic plate to support the fat pad in 13 (50%) patients, secured with mini screws. The use of a splint to support and protect the flap allowed early feeding.

Single incision laparoscopic cholecystectomy: A review on the complications

BACKGROUND:

The aim of this study was to establish the incidence of postoperative complications after single incision laparoscopic cholecystectomy.

MATERIALS AND METHODS:

A literature search was performed using the PubMed database. Search terms included single incision laparoscopic cholecystectomy, single port cholecystectomy, minimal invasive laparoscopic cholecystectomy, nearly scarless cholecystectomy and complications.

RESULTS:

A total of 38 articles meeting the selection criteria were reviewed. A total of 1180 patients were selected to undergo single incision laparoscopic cholecystectomy. Introduction of extra ports was necessary in 4% of the patients. Conversion to open cholecystectomy was required in 0.4% of the patients. Laparoscopic cholangiography was attempted in 4% of the patients. The incidence of major complications requiring surgical intervention or ERCP with stenting was 1.7%. The mortality rate was zero.

CONCLUSION:

Although the number of complications after single incision laparoscopic cholecystectomy seems favourable, it is too early to conclude that single incision laparoscopic cholecystectomy is a safe procedure. Large randomised controlled trials will be necessary to further establish its safety.

The use of curved vs. straight instruments in single port access surgery, on standardized box trainer tasks

Background

Single-port access (SPA) surgery is a novel surgical technique to create nearly “scarless” surgery. SPA surgery appears to be safe and feasible, but the exposure and handling of tissue may not be optimal. Therefore, the performance of SPA surgery with different instruments used and conventional laparoscopy is compared.

Methods

Fifteen participants (>50 laparoscopic procedures) performed three basic tasks (translocation, clip & cut, and tissue dissection, based on the fundamentals of laparoscopic surgery) in the box trainer in laparoscopy and SPA settings with both (conventional) crossed and curved instruments. All participants completed a questionnaire, which asked their opinion on the use of instruments and preference.

Results

Translocation was performed significantly faster in both laparoscopy and SPA crossed than SPA curved (means, 130.3 and 137.7 vs. 170.7 sec; p < 0.001 and p = 0.005). The errors also were less in laparoscopy and SPA crossed (means, 0.9 and 1.2 vs. 1.6), but not significant. The time to complete the dissection was almost equal between laparoscopy and SPA curved settings, but took longer for SPA crossed, although not significantly (148.1 and 150.8 vs. 179.5 sec). The errors only differed significantly between laparoscopy and SPA crossed (means, 0.5 vs. 1.27; p = 0.044). Fourteen participants still favored conventional laparoscopy and one SPA curved. They also thought SPA curved was better than crossed (means, 3.6 vs. 2.47; p = 0.003) and that exposure is superior in curved (means, 3.4 vs. 2.27; p = 0.002).

Conclusions

Although conventional laparoscopy may appear most effective for proper dissection and exposure of tissue, single-port access surgery shows potential. Especially in the tissue dissection task, there is no significant difference in time or errors between conventional laparoscopy and SPA surgery, using specially designed curved instruments. Although the participants favor conventional laparoscopy, this could evolve to a more accepting mind when SPA surgery becomes more available and used in the clinical setting.

Follow-up period of 13 years after endoscopic total extraperitoneal repair of inguinal hernias: a cohort study

BACKGROUND

Endoscopic inguinal hernia repair was introduced in the Netherlands in the early 1990s. The authors' institution was among the first to adopt this technique. In this study, long-term hernia recurrence among patients treated by the total extraperitoneal (TEP) approach for an inguinal hernia is described. A cohort study was conducted.

METHODS

Between January 1993 and December 1997, 346 TEP hernia repairs were performed for 318 patients. After a mean follow-up period of 13-years, a senior resident examined each patient. An experienced surgeon subsequently examined the patients with a diagnosis of recurrent hernia. Data were collected on an intention-to-treat basis, meaning that conversions were included in the analysis. Univariant tests were used to analyze age older than 50 years, chronic obstructive pulmonary disease, body mass index, smoking habit, hernia type, history of open hernia repair, conversion, and surgeon as potential risk factors.

RESULTS

The analysis included 191 patients (62%) with 213 hernias. Of the original 318 patients, 59 patients died, and 68 were lost to follow-up evaluation. Perioperatively, 105 lateral, 55 medial, and 53 pantalon hernias were observed. Of the 213 hernias, 176 were primary and 37 were recurrent. The overall recurrence rate was 8.9% (8.5% for primary and 10.8% for recurrent hernias). Of the total study group, 48% of the patients experienced a bilateral inguinal hernia during their lifetime. No predicting factor for recurrent hernia could be identified.

CONCLUSIONS

The current long-term results for TEP repair of primary and secondary inguinal hernia show an overall recurrence rate of 8.9%, which is slightly higher than in previous studies. The thorough examination at follow-up assessment, the learning curve effect, and the intention-to-treat-analysis may have influenced the observed recurrence rate. Also, the percentage of bilateral hernias was higher than known to date. Therefore, examination of the contralateral side should be standard procedure.

Laparoscopic diagnosis and treatment of idiopathic segmental infarction of the greater omentum. Case report

Acute pain at the right side of the abdomen rarely is caused by idiopathic segmental infarction of the greater omentum (ISIGO). In most cases the patient is presumed to suffer from appendicitis or cholecystitis. Although some radiologic signs might suggest ISIGO, this rare clinical entity mostly is diagnosed perioperatively and confirmed by postoperative pathologic findings. In the reported case, a patient is described with acute right-side abdominal pain of unknown origin, in whom ISIGO was encountered during diagnostic laparoscopy and successfully resected. Because of this minimally invasive approach, the patient was discharged the day after surgery and returned to work after 5 days. The pathogenesis, symptoms, and treatment methods are discussed.

Peri-implant soft tissue maintenance in patients with craniofacial implant retained prostheses

The aim of this pilot study was to describe the effectiveness of a hygiene protocol prescribed for patients receiving craniofacial implant retained prostheses. Eleven subjects receiving either orbital or auricular prostheses were instructed by a hygienist in debris removal procedures. Patients were re-examined on at least four occasions over the following 18 months, and tissue health around the implant abutments was evaluated using standard criteria. In most cases, adequate debris removal was demonstrated, particularly when hygiene procedures were reinforced at the second follow-up visit. Barriers to maintenance of tissue health included inadequate space between fixtures and thickness of skin around abutments. Occasionally, prostheses had to be replaced due to inappropriate cleaning methods. The intensive hygiene regimen helped maintain tissue health around implant abutments, although it was demanding in terms of professional time.

Do you care? A national register for cleft lip and palate patients

The Cleft Palate Index and, more recently, the Craniofacial Anomalies Register--CARE--have been in operation since 1982. This paper summarizes its development and plans for the future. CARE is a multidisciplinary committee involving all specialties involved in the treatment of this group of patients therefore it should and can be well placed to co-ordinate the cleft data arising from these patients.

Bacteraemia during prostatectomy and other transurethral operations: influence of timing of antibiotic administration

The relation between the timing of prophylactic antibiotic administration and the occurrence of bacteraemia during transurethral operations was studied in 112 patients whose urine was infected before operation. Blood cultures taken during operation were positive in 15 (60%) of 25 patients who did not receive appropriate antibiotics, in 13 (21%) of 63 patients who were given appropriate antibiotics less than 24 h before operation, and in none of 24 patients in whom antibiotic "cover" was started more than 24 h before operation. In all cases the bacteraemia was transient. No patient developed septicaemia. The implications of these findings for the optimum timing of antibiotic administration to patients with preoperative bacteriuria are discussed.
