Laparoscopic insertion of a magnetic ring for gastro-oesophageal reflux disease

Evidence-based recommendations on laparoscopic insertion of a magnetic ring for gastro-oesophageal reflux disease. This involves placing a ring of beads outside of the food pipe, just above the stomach. Magnets inside the beads hold them together to keep the food pipe closed but are weak enough to move apart to allow food or liquid to be swallowed. The aim is to prevent acid reflux. Is this guidance up to date? Next review: this guidance will be reviewed if there is new evidence or safety concerns.

System Factors Affecting Intraoperative Risk and Resilience: Applying a Novel Integrated Approach to Study Surgical Performance and Patient Safety.

OBJECTIVE: To identify and categorize system factors in complex laparoscopic surgery that have the potential to either threaten patient safety or support system resilience. BACKGROUND: The operating room is a uniquely complex sociotechnical work system wherein surgical successes prevail despite pervasive safety threats. Holistically characterizing intraoperative factors that thus support system resilience in addition to those that threaten patient safety using contextual methodologies is critical for optimizing surgical safety overall. METHOD: In this prospective descriptive interdisciplinary study, 19 audio/video recordings of complex laparoscopic general surgical procedures were directly observed and transcribed. Using a qualitative systems-based approach, intraoperative human factors with the potential to impact patient safety, either as a safety threat or as a support for resilience, were identified. Adverse events were further assessed for shared threats and supports. Data collection was guided by the Systems Engineering Initiative for Patient Safety 2.0 work system model. RESULTS: A total of 1083 relevant observations were made over 39.8 hours of operative time, enabling the identification of 79 distinct safety threats and 67 resilience supports within the surgical system. Safety threats associated with the physical environment, tasks, organization, and equipment were prevalent and observed in equal measure, whereas supports for resilience were predominantly attributed to clinician behaviors, including proactive team management and skills coaching. Two subclinical adverse events were identified; shared safety threats included suboptimal technology design, whereas shared resilience supports included calm clinician behavior and redundant intraoperative resourcing. CONCLUSIONS: Safety threats and resilience supports were found to be systematic in the surgical setting. Identified safety threats should be prioritized for remediation, and clinician behaviors that contribute to fostering resilience should be valued and protected.

Implementation of a pediatric enhanced recovery pathway decreases opioid utilization and shortens time to full feeding.

BACKGROUND: We hypothesized that an enhanced recovery after surgery (ERAS) pathway for pediatric patients undergoing surgery for inflammatory bowel disease (IBD) would be beneficial. METHODS: This is a single institution retrospective comparative study comparing patients treated with an ERAS pathway to consecutive patients in a Preimplementation Cohort (PIC) with similar open and laparoscopic surgeries for IBD. The pathway emphasized minimal preoperative fasting, multimodal and regional analgesia, and early enteral nutrition after surgery. Primary endpoints were time to 120 mL of PO intake (POI), length of stay (LOS), opioid utilization, and 30-day surgical outcomes. Continuous and categorical variables were compared (p < 0.05). RESULTS: There were 23 PIC and 28 ERAS patients with similar demographic data and surgical and anesthetic approaches. ERAS patients experienced a significant increase in the use of regional anesthesia, faster time to POI, and a nonsignificant decrease in mean LOS. ERAS patients had decreased total and daily opioid use with similar complication rates. CONCLUSION: This study demonstrates the effectiveness of a pediatric ERAS pathway for IBD patients requiring laparoscopic and (unique to this study) open surgery. The study demonstrates that opioid utilization and time to feeding can be positively impacted using ERAS pathways without negatively impacting outcomes. TYPE OF STUDY: Retrospective comparative study. LEVEL OF EVIDENCE: Level III.

Role of diagnostic laparoscopy in patients with suspicion of colorectal peritoneal metastases to evaluate suitability for cytoreductive surgery with hyperthermic intraperitoneal chemotherapy.

Background: The aim of the present study was to determine the feasibility and safety of performing diagnostic laparoscopy (DLS) routinely in patients with suspicion of colorectal peritoneal metastases (PM) to evaluate suitability for cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS + HIPEC). Methods: Data for consecutive patients who underwent DLS between 2012 and 2018 were extracted retrospectively from an institutional database. The primary outcome was the degree of visibility of the abdominal cavity during DLS. Good laparoscopic evaluation of the abdominal cavity was defined as visibility of at least the regions of the diaphragm, pelvis and small bowel. Secondary outcomes were reasons for perioperative exclusion for CRS + HIPEC, major postoperative complications (Clavien-Dindo grade III or above) and difference in overall survival (OS) between patients deemed suitable or unsuitable for CRS + HIPEC. Kaplan-Meier analyses were performed. Results: Some 184 patients were analysed. Good laparoscopic evaluation was possible in 138 patients (75·0 per cent), and 24 (13·0 per cent) had conversion to an open procedure. Ninety-three patients (50·5 per cent) were excluded for CRS + HIPEC, most commonly because of absence of colorectal PM (34 patients, 37 per cent) or extensive disease (Peritoneal Cancer Index 20 or above) (33 patients, 35 per cent). Major complications occurred in five patients (2·7 per cent), with no postoperative deaths. Median OS was significantly decreased in patients who were excluded due to extensive disease (14 (95 per cent c.i. 10 to 18) months) compared with patients suitable for CRS + HIPEC (36 (27 to 45) months) (P < 0·001). Conclusion: Routinely performing DLS in patients with suspicion of colorectal PM to evaluate suitability for CRS + HIPEC is feasible and safe, avoiding the morbidity of an unnecessary laparotomy in patients with extensive disease.

Antecedentes: El objetivo del presente estudio fue determinar la viabilidad y seguridad de realizar una laparoscopia diagnóstica (diagnostic laparoscopy, DLS) de rutina en pacientes con sospecha de metástasis peritoneal (peritoneal metastasis, PM) de origen colorrectal para evaluar la idoneidad para la cirugía citorreductora con quimioterapia intraperitoneal hipertérmica (cytoreductive surgery + hyperthermic intraperitoneal chemotherapy, CRS+HIPEC). Métodos: Los datos de los pacientes consecutivos que fueron sometidos a DLS entre 2012 y 2018 se obtuvieron retrospectivamente de una base de datos institucional. La visualización de al menos las regiones de los diafragmas, pelvis e intestino delgado se definió como una correcta evaluación laparoscópica de la cavidad abdominal. Los resultados secundarios fueron las complicaciones postoperatorias mayores (Clavien­Dindo grado ≥ III), razones para la exclusión perioperatoria para CRS+HIPEC y diferencia en supervivencia global (overall survival, OS) entre pacientes que se consideraron apropiados y no apropiados para CRS+HIPEC. Se realizaron análisis de Kaplan­Meier y análisis de riesgos proporcionales. Resultados: Se analizaron 181 pacientes. En 138 pacientes (75,0%) fue posible una adecuada evaluación laparoscópica, mientras que 24 casos (13%) fueron convertidos a un procedimiento abierto. Se excluyeron 93 (50,5%) pacientes para CRS+HIPEC, más comúnmente por la ausencia de PM colorrectales (36,6%) o enfermedad extensa (37,6%). En cinco pacientes aparecieron complicaciones mayores (2,7%), sin mortalidad postoperatoria. La mediana de la OS disminuyó de forma significativa en pacientes que fueron excluidos debido a enfermedad extensa (14 meses, i.c. del 95% 10­18) en comparación con pacientes idóneos para CRS+HIPEC (35 meses, i.c. del 95% 30­40, P < 0,0001). Conclusión: La realización rutinaria de DLS en pacientes con sospecha de PM de origen colorrectal para evaluar la idoneidad de la CRS+HIPEC es viable y segura. La morbilidad de una laparotomía innecesaria puede prevenirse en pacientes con enfermedad extensa o ausencia de PM colorrectales.

Update of Guidelines for laparoscopic treatment of ventral and incisional abdominal wall hernias (International Endohernia Society (IEHS)): Part B.

In 2014 the International Endohernia Society (IEHS) published the first international "Guidelines for laparoscopic treatment of ventral and incisional abdominal wall hernias". Guidelines reflect the currently best available evidence in diagnostics and therapy and give recommendations to help surgeons to standardize their techniques and to improve their results. However, science is a dynamic field which is continuously developing. Therefore, guidelines require regular updates to keep pace with the evolving literature. METHODS: For the development of the original guidelines all relevant literature published up to year 2012 was analyzed using the ranking of the Oxford Centre for Evidence-Based-Medicine. For the present update all of the previous authors were asked to evaluate the literature published during the recent years from 2012 to 2017 and revise their statements and recommendations given in the initial guidelines accordingly. In two Consensus Conferences (October 2017 Beijing, March 2018 Cologne) the updates were presented, discussed, and confirmed. To avoid redundancy, only new statements or recommendations are included in this paper. Therefore, for full understanding both of the guidelines, the original and the current, must be read. In addition, the new developments in repair of abdominal wall hernias like surgical techniques within the abdominal wall, release operations (transversus muscle release, component separation), Botox application, and robot-assisted repair methods were included. RESULTS: Due to an increase of the number of patients and further development of surgical techniques, repair of primary and secondary abdominal wall hernias attracts increasing interests of many surgeons. Whereas up to three decades ago hernia-related publications did not exceed 20 per year, currently this number is about 10-fold higher. Recent years are characterized by the advent of new techniques-minimal invasive techniques using robotics and laparoscopy, totally extraperitoneal repairs, novel myofascial release techniques for optimal closure of large defects, and Botox for relaxing the abdominal wall. Furthermore, a concomitant rectus diastasis was recognized as a significant risk factor for recurrence. Despite still insufficient evidence with respect to these new techniques it seemed to us necessary to include them in the update to stimulate surgeons to do research in these fields. CONCLUSION: Guidelines are recommendations based on best available evidence intended to help the surgeon to improve the quality of his daily work. However, science is a continuously evolving process, and as such guidelines should be updated about every 3 years. For a comprehensive reference, however, it is suggested to read both the initially guidelines published in 2014 together with the update. Moreover, the presented update includes also techniques which were not known 3 years before.

Implementing Cognitive Training Into a Surgical Skill Course: A Pilot Study on Laparoscopic Suturing and Knot Tying.

Mini-invasive surgery-for example, laparoscopy-has challenged surgeons' skills by extending their usual haptic space and displaying indirect visual feedback through a screen. This may require new mental abilities, including spatial orientation and mental representation. This study aimed to test the effect of cognitive training based on motor imagery (MI) and action observation (AO) on surgical skills. A total of 28 postgraduate residents in surgery took part in our study and were randomly distributed into 1 of the 3 following groups: (1) the basic surgical skill, which is a short 2-day laparoscopic course + MI + AO group; (2) the basic surgical skill group; and (3) the control group. The MI + AO group underwent additional cognitive training, whereas the basic surgical skill group performed neutral activity during the same time. The laparoscopic suturing and knot tying performance as well as spatial ability and mental workload were assessed before and after the training period. We did not observe an effect of cognitive training on the laparoscopic performance. However, the basic surgical skill group significantly improved spatial orientation performance and rated lower mental workload, whereas the 2 others exhibited lower performance in a mental rotation test. Thus, actual and cognitive training pooled together during a short training period elicited too high a strain, thus limiting potential improvements. Because MI and AO already showed positive outcomes on surgical skills, this issue may, thus, be mitigated according to our specific learning conditions. Distributed learning may possibly better divide and share the strain associated with new surgical skills learning.

Technical standardization of laparoscopic repair of Morgagni diaphragmatic hernia in children: results of a multicentric survey on 43 patients.

BACKGROUND: This study aimed to standardize the surgical correction technique of congenital Morgagni diaphragmatic hernia (CMDH), analyzing the results of an international multicentric survey. METHODS: The medical records of 43 patients (29 boys, 14 girls) who underwent laparoscopic repair of CMDH in 8 pediatric surgery units in a 5-year period were retrospectively reviewed. Their average age was 3.3 years. Ten patients (23.2%) presented associated malformations: 9 Down syndrome (20.9%) and 1 palate cleft (2.3%). Thirty-five patients (81.4%) were asymptomatic, whereas 8 patients (18.6%) presented symptoms such as respiratory distress, cough or abdominal pain. As for preoperative work-up, all patients received a chest X-ray (100%), 15/43 (34.8%) a CT scan, 8/43 (18.6%) a barium enema and 4/43 (9.3%) a US. RESULTS: No conversion to open surgery was reported. Average operative time was 61.2 min (range 45-110 min). In 38/43 (88.3%) patients, a trans-parietal stitch was positioned in order to reduce the tension during the repair. In 14/43 cases (32.5%), the sac was resected; in only 1/43 case (2.3%) a dual mesh of goretex was adopted to reinforce the closure. Average hospital stay was 2.8 days. The average follow-up was 4.2 years, and it consisted in annual clinical controls and chest X-ray. We recorded 2 complications (4.6%): one small pleural opening that required no drain and one recurrence (2.3%), re-operated in laparoscopy, with no further recurrence. CONCLUSIONS: To the best of our knowledge, this is the largest series published in the literature on this topic. Laparoscopic CMDH repair is well standardized: The full-thickness anterior abdominal wall repair using non-resorbable suture with interrupted stitches is the technique of choice. Postoperative outcome was excellent. Recurrence rate was very low, about 2% in our series. We believe that children with CMDH should be always treated in laparoscopy following the technical details reported in this paper.

[Hysterectomy for benign pathology: Guidelines for clinical practice]. / Hystérectomie pour pathologie bénigne: recommandations pour la pratique clinique.

OBJECTIVE: The objective of the study was to provide guidelines for clinical practice from the French college of obstetrics and gynecology (CNGOF), based on the best evidence available, concerning hysterectomy for benign pathology. METHODS: Each recommendation for practice was allocated a grade which depends on the level of evidence (guidelines for clinical practice method). RESULTS: Hysterectomy should be performed by a high volume surgeon (>10 procedures of hysterectomy per year) (grade C). Rectal enema stimulant laxatives are not recommended prior to hysterectomy (grade C). It is recommended to carry out vaginal disinfection using povidone iodine solution prior to an hysterectomy (grade B). Antibioprophylaxis is recommended during a hysterectomy, regardless of the surgical route (grade B). The vaginal or the laparoscopic routes are recommended for hysterectomy for benign pathology (grade B), even if the uterus is large and/or the patient is obese (grade C). The choice between these two surgical approaches depends on others parameters, such as the surgeon's experience, the mode of anesthesia and organizational constraints (operative duration and medico economic factors). Hysterectomy by vaginal route is not contraindicated in nulliparous women (grade C) or in women with previous c-section (grade C). No specific technique to achieve hemostasis is recommended with a view to avoid urinary tract injuries (grade C). In the absence of ovarian pathology and personal or family history of breast/ovarian carcinoma, it is recommended to conserve ovaries in pre-menopausal women (grade B). Subtotal hysterectomy is not recommended in order to diminish the risk of per- or postoperative complications (grade B). CONCLUSION: The application of these recommendations should minimize risks associated with hysterectomy.

Feasibility and impact of an evidence-based program for gastric bypass surgery.

BACKGROUND: Health care in the United States is expensive and quality is variable. The aim of this study was to investigate whether our integrated health system, composed of academic hospitals, a practice plan, and a managed care payer, could reliably implement an evidence-based program for gastric bypass surgery. A secondary aim was to evaluate the impact of the program on clinical outcomes. STUDY DESIGN: A standardized program for delivery of clinical best-practice elements for patients undergoing initial open or laparoscopic Roux-en-Y gastric bypass was implemented in 2008. Best-practice elements were embedded into the workflow. The best-practice elements were refined after reviewing failures observed during the early implementation period. The study period was divided into 3 groups: group α = year preceding program implementation (control), group ß = first year of implementation (unreliable), and group Ω = 2nd to 4th years of implementation (reliable). Outcomes data were collected for all patients who had undergone Roux-en-Y gastric bypass between May 2008 and April 2012 and were compared with a control group from the preceding year using multiple logistic regression analysis. RESULTS: Two thousand and sixty-one patients were studied, with no significant demographic differences between study groups. Best-practice elements delivery was 40% in group ß, but was >90% for group Ω (p < 0.001). Length of stay for group α was 3.5 days and improved to 2.2 days (p < 0.001) for group Ω. Complications and readmission rates improved considerably with reliable delivery of best-practice elements. CONCLUSIONS: Standardization of evidence-based care delivery for Roux-en-Y gastric bypass was feasible and reliable delivery of this pathway improved clinical outcomes.

Randomized clinical trial to evaluate mental practice in enhancing advanced laparoscopic surgical performance.

BACKGROUND: Mental practice, the cognitive rehearsal of a task without physical movement, is known to enhance performance in sports and music. Investigation of this technique in surgery has been limited to basic operations. The purpose of this study was to develop mental practice scripts, and to assess their effect on advanced laparoscopic skills and surgeon stress levels in a crisis scenario. METHODS: Twenty senior surgical trainees were randomized to either conventional training or mental practice groups, the latter being trained by an expert performance psychologist. Participants' skills were assessed while performing a porcine laparoscopic jejunojejunostomy as part of a crisis scenario in a simulated operating room, using the Objective Structured Assessment of Technical Skill (OSATS) and bariatric OSATS (BOSATS) instruments. Objective and subjective stress parameters were measured, as well as non-technical skills using the Non-Technical Skills for Surgeons rating tool. RESULTS: An improvement in OSATS (P = 0.003) and BOSATS (P = 0.003) scores was seen in the mental practice group compared with the conventional training group. Seven of ten trainees improved their technical performance during the crisis scenario, whereas four of the ten conventionally trained participants deteriorated. Mental imagery ability improved significantly following mental practice training (P = 0.011), but not in the conventional group (P = 0.083). No differences in objective or subjective stress levels or non-technical skills were evident. CONCLUSION: Mental practice improves technical performance for advanced laparoscopic tasks in the simulated operating room, and allows trainees to maintain or improve their performance despite added stress.

Ductal pancreatic adenocarcinoma.

BACKGROUND: Ductal adenocarcinoma of the pancreas is the fourth most common cause of death from cancer in men and women in Germany: about 15 000 persons die of this disease each year. METHOD: The S3 guideline on exocrine pancreatic carcinoma was updated with the aid of systematic literature reviews on the surgical, neoadjuvant, and adjuvant treatment of ductal pancreatic carcinoma, and on treatment in the metastatic stage. These reviews covered the periods 2002 to February 2012 (for radiotherapy) and 2006 to August 2011 (for all other topics). RESULTS: The criteria for borderline resectable pancreatic tumors are the same as those of the guidelines of the National Comprehensive Cancer Network. Preoperative biliary drainage with a stent is recommended only if cholangitis is present or if a planned operation cannot be performed soon after the diagnosis is made. When a pancreatic carcinoma is resected, at least 10 regional lymph nodes should be excised, and the ratio of affected to excised nodes should be documented in the pathology report. Gemcitabine and 5-fluorouracil are recommended for adjuvant therapy. Neither of these drugs is preferred over the other; if the one initially given is poorly tolerated, the other one should be given instead. When gemcitabine and erlotinib are given for palliative treatment, erlotinib should be given for no longer than 8 weeks if no skin rash develops. In selected patients, the folfirinox protocol yields markedly better results than gemcitabin. Moreover, the new combination of nab-paclitaxel and gemcitabine can be used as first-line treatment. In the event of disease progression under first-line treatment, second-line treatment should be initiated. CONCLUSION: In recent years, new chemotherapeutic protocols have brought about marked improvement in palliative care. Further trials are needed to determine whether the perioperative or adjuvant use of these protocols might also improve the outcome of surgical treatment with curative intent.

Multidisciplinary laparoscopic treatment for bowel endometriosis.

Endometriosis is a handicapping disease affecting young females in the reproductive period. It mainly occurs in the pelvis and affects the bowel in 3-37%. Endometriosis can cause menstrual and non-menstrual pelvic pain and infertility. Colorectal involvement results in alterations of bowel habit such as constipation, diarrhoea, tenesmus, and rarely rectal bleeding. A precise diagnosis about the presence, location and extent is necessary. Based on clinical examination, the diagnosis of bowel endometriosis can be made by transvaginal ultrasound, barium enema examination and magnetic resonance imaging. Multidisciplinary laparoscopic treatment has become the standard of care and depending on size of the lesion and site of involvement full-thickness disc excision or bowel resection is performed by an experienced colorectal surgeon. Anastomotic complications occur around 1%. Long-term outcome after bowel resection for severe endometriosis is good with a pregnancy rate of 50%.

Quality of laparoscopic radical hysterectomy in developing countries: a comparison of surgical and oncologic outcomes between a comprehensive cancer center in the United States and a cancer center in Colombia.

OBJECTIVE: To help determine whether global collaborations for prospective gynecologic surgery trials should include hospitals in developing countries, we compared surgical and oncologic outcomes of patients undergoing laparoscopic radical hysterectomy at a large comprehensive cancer center in the United States and a cancer center in Colombia. METHODS: Records of the first 50 consecutive patients who underwent laparoscopic radical hysterectomy at The University of Texas MD Anderson Cancer Center in Houston (between April 2004 and July 2007) and the first 50 consecutive patients who underwent the same procedure at the Instituto de Cancerología-Clínica las Américas in Medellín (between December 2008 and October 2010) were retrospectively reviewed. Surgical and oncologic outcomes were compared between the 2 groups. RESULTS: There was no significant difference in median patient age (US 41.9 years [range 23-73] vs. Colombia 44.5 years [range 24-75], P=0.09). Patients in Colombia had a lower median body mass index than patients in the US (24.4 kg/m(2) vs. 28.7 kg/m(2), P=0.002). Compared to patients treated in Colombia, patients who underwent surgery in the US had a greater median estimated blood loss (200 mL vs. 79 mL, P<0.001), longer median operative time (328.5 min vs. 235 min, P<0.001), and longer postoperative hospital stay (2 days vs. 1 day, P<0.001). CONCLUSIONS: Surgical and oncologic outcomes of laparoscopic radical hysterectomy were not worse at a cancer center in a developing country than at a large comprehensive cancer center in the United States. These results support consideration of developing countries for inclusion in collaborations for prospective surgical studies.

Impact of clinical pathways in surgery.

BACKGROUND: One strategy to reduce the consumption of resources associated to specific procedures is to utilize clinical pathways, in which surgical care is standardized and preset by determination of perioperative in-hospital processes. The aim of this prospective study was to establish the impact of clinical pathways on costs, complication rates, and nursing activities. METHOD: Data was prospectively collected for 171 consecutive patients undergoing laparoscopic cholecystectomy (n = 50), open herniorrhaphy (n = 56), and laparoscopic Roux-en-Y gastric bypass (n = 65). RESULTS: Clinical pathways reduced the postoperative hospital stay by 28% from a mean of 6.1 to 4.4 days (p < 0.001), while the 30-day readmission rate remained unchanged (0.5% vs. 0.45%). Total mean costs per case were reduced by 25% from euro 6,390 to euro 4,800 (p < 0.001). Costs for diagnostic tests were reduced by 33% (p < 0.001). Nursing hours decreased, reducing nursing costs by 24% from euro 1,810 to euro 1,374 (p < 0.001). A trend was noted for lower postoperative complication rates in the clinical pathway group (7% vs. 14%, p = 0.07). CONCLUSIONS: This study demonstrates clinically and economically relevant benefits for the utilization of clinical pathways with a reduction in use of all resource types, without any negative impact on the rate of complications or re-hospitalization.

Electrical stimulation for gastroparesis. Gastric motility restored.

BACKGROUND: Gastroparesis is a disabling, and sometimes fatal, disease that often does not respond to medical treatment. This single-surgeon prospective study examines the safety and 6-month efficacy of electrical stimulation for the treatment of gastroparesis. METHODS: Sixteen patients with medically refractory gastroparesis underwent laparoscopic implantation of an electrical stimulator device (Enterra Therapy, Medtronic, Minneapolis, MN, USA) consisting of a subcutaneous stimulator and two gastric wall leads. Gastric emptying scans (GES) confirmed the diagnosis of gastroparesis. Patients were evaluated preoperatively using a self-administered GI symptomatology questionnaire and RAND 36 Health Survey. Once patients were >6-months from implantation, a repeat GES was obtained and patients completed a postoperative GI symptomatology questionnaire and RAND 36 Health Survey. Ten of 16 patients in this case series were >6-months from implantation. One was lost to follow-up. An F-test was used to establish equality of standard deviations between the 16 patients evaluated preoperatively and the subset of 10 patients evaluated postoperatively. A Student's t-test was used to evaluate the significance of differences in pre- and postoperative results. RESULTS: Average operating time was 117 min with no intraoperative complications. The majority of patients were discharged on postoperative day 1. There were two complications in the postoperative period. Patients experienced a significant decrease in nausea and vomiting as measured by the GI symptomatology questionnaire. Half of all patients no longer required gastric prokinetic medications and there was a subjective reduction of pyrosis, early satiety, and epigastric pain. A significant increase in quality of life as measured by the RAND 36 Health Survey was seen, and six of eight patients no longer demonstrated gastroparesis on GES. CONCLUSION: Laparoscopic implantation of an electrical stimulation device is a safe and effective treatment by subjective and objective standards for the management of medically refractory gastroparesis.

[Diagnostic laparoscopy under local anaesthesia]. / Diagnostisk laparoskopi under lokal anaestesi.

Laparoscopy under local anaesthesia (LULA) is a safe, feasible and well-tolerated procedure. LULA has been successfully used for such outpatient gynaecological procedures as diagnosis of chronic pelvic pain and sterilisation. Single studies have indicated that LULA can be performed for diagnosis of possible intra-abdominal catastrophe in ICU patients, appendectomy and preperitoneal inguinal hernia repair. LULA in abdominal surgery for diagnosis of conditions presenting with acute lower abdominal pain is being introduced at our institution. This paper describes the possible applications of LULA in current practice as well as the technical aspects of the procedure.

Utilidad de la laparoscopia en el abdomen agudo de la mujer en edad fértil / Utility of laparoscopy in acute abdomen in women of childbearing age

Introducción. El objetivo de este trabajo es analizar la utilidad del abordaje laparoscópico para establecer un diagnóstico y tratamiento correcto en mujeres jóvenes que se operan con dolor agudo en la fosa ilíaca derecha. Pacientes y método. Operamos por laparoscopia a 167 mujeres de entre 12 y 49 años de edad que fueron vistas en urgencias de nuestro hospital con dolor agudo en la fosa ilíaca derecha. Las mujeres con sospecha de apendicitis aguda eran operadas por laparoscopia siempre que hubiera el material necesario y un cirujano con experiencia suficiente en esta técnica. No hubo otros criterios de exclusión. El período estudiado fue entre junio de 1991 y diciembre de 1997. Estudiamos los hallazgos operatorios, la tasa de conversión a laparotomía, las complicaciones, el tiempo operatorio y la estancia operatoria. Resultados. Se confirmó una apendicitis aguda en 128 de las 167 pacientes (76,6 por ciento). De las 39 restantes (23,3 por ciento), 26 (66,6 por ciento) presentaban alguna patología ginecológica que justificaba los síntomas. En sólo 4 pacientes no encontramos ninguna patología abdominal causante del dolor abdominal. La tasa de conversión fue del 6 por ciento. Diez pacientes (6 por ciento) sufrieron complicaciones directamente relacionadas con la cirugía. Conclusiones. La laparoscopia es un método con alta capacidad diagnóstica (97,6 por ciento) que permite diagnosticar y resolver la mayoría de los cuadros que causan dolor agudo en la fosa ilíaca derecha (AU)

How well can surgeons perform colonoscopy?

BACKGROUND: Little recent data exist relative to the efficacy or postprocedural complications of surgeons performing diagnostic or therapeutic colonoscopy. Therefore, the aim of this study was to retrospectively assess the outcome of colonoscopy performed by surgeons. METHODS: The charts of 2,069 patients who underwent colonoscopy between January 1992 and April 1995 by one of four surgeons at one of two centers were reviewed. Parameters included demographics, indications, procedures and findings, pathology, major complications, length of procedures and dosage of medication. RESULTS: 2,069 colonoscopies were performed for the following indications: 877 polyp surveillance, 509 cancer surveillance, 287 rectal bleeding, 282 family history of colon cancer, 127 change in bowel habits, 112 polyps found by flexible sigmoidoscope or barium enema, 92 inflammatory bowel disease, 48 preoperation, and 58 other indications. Some patients had more than one indication. The cecum could not be intubated in 73 cases (3.5%) due to narrowing and stricture [33] redundancy [18], poor preparation [14], and other miscellaneous conditions [8]. The average procedure time in the 1, 023 cases in which it was measured was 34.7 min. Average sedation doses were 2.1 mg of midazolam and 75.2 mg of meperedine in these same cases. The 2,069 colonoscopies included 1,878 biopsies, 353 polypectomies, and 139 other procedures. Some patients had multiple therapeutic interventions. Findings included 2,107 polyps, the pathology of which included 907 tubular; 62 tubulovillous and 41 villous adenomas, 325 hyperplastic polyps, and 68 carcinomas. There were five major complications after polypectomies (0.2%) including two cases of bleeding and three perforations. The two patients with bleeding were admitted to hospital, one for observation for 2 days and the other for colonoscopy, coagulation, and transfusion of 3 units of blood. Of the three patients with perforation, one underwent hospitalization for intravenous antibiotics and the other two for surgery (0.01%). Surgery included one resection with primary closure of the sigmoid perforation and one colostomy. CONCLUSIONS: This study confirms the observation that colonoscopy performed by surgeons is safe and rapid whether performed as a therapeutic or as a diagnostic procedure.
