Incidence and risk factors for trocar-site incisional hernia detected by clinical and ultrasound examination: a prospective observational study.

BACKGROUND: Trocar site incisional hernia (TSIH) is the most frequent complication associated with laparoscopic surgery. Few studies currently describe its incidence or risk factors. The aim of this report is to determine the real incidence of TSIH and to identify risk factors. METHODS: A cross-sectional prospective study was performed including consecutive patients who underwent a laparoscopic procedure during a 4 months period. All the patients were assessed both clinically (TSIHc) and by an ultrasonographic examination (TSIHu). The main variable studied was the incidence of TSIH. A multivariate analysis was performed to identify risk factors. RESULTS: 76 patients were included. 27.6% of patients were clinically diagnosed as having TSIH (TSIHc) but only 23.7% of those cases were radiologically confirmed (TSIHu). In the logistic regression analysis, age > 70 years (OR 3.462 CI 1.14-10.515, p = 0.028) and body mass index (BMI) ≥ 30 kg/m2 (OR 3.313 CI 1.037-10.588, p = 0.043) were identified as risk factors for TSIH. The size of the trocar also showed statistically significant differences (p < 0.001). Mean follow-up time was 34 months. CONCLUSIONS: TSIH is under-diagnosed due to the lack of related symptomatology and the inadequacy of the postoperative follow-up period. We detected discrepancies between the clinical and ultrasonographic examinations. TSIHu should be considered as the gold standard for the diagnosis of TSIH. Risk factors such as age, BMI and size of the trocar were confirmed. Patients should be followed-up for a minimum of 2 years. Trial registration The study has been retrospectively registered in Clinicaltrials.gov on June 4, 2020 under registration number: NCT04410744.

Sleeve gastrectomy effects on hunger, satiation, and gastrointestinal hormone and motility responses after a liquid meal test.

BACKGROUND: The relation between hunger, satiation, and integrated gastrointestinal motility and hormonal responses in morbidly obese patients after sleeve gastrectomy has not been determined. OBJECTIVE: The objective was to assess the effects of sleeve gastrectomy on hunger, satiation, gastric and gallbladder motility, and gastrointestinal hormone response after a liquid meal test. DESIGN: Three groups were studied: morbidly obese patients (n = 16), morbidly obese patients who had had sleeve gastrectomy (n = 8), and nonobese patients (n = 16). The participants fasted for 10 h and then consumed a 200-mL liquid meal (400 kcal + 1.5 g paracetamol). Fasting and postprandial hunger, satiation, hormone concentrations, and gastric and gallbladder emptying were measured several times over 4 h. RESULTS: No differences were observed in hunger and satiation curves between morbidly obese and nonobese groups; however, sleeve gastrectomy patients were less hungry and more satiated than the other groups. Antrum area during fasting in morbidly obese patients was statistically significant larger than in the nonobese and sleeve gastrectomy groups. Gastric emptying was accelerated in the sleeve gastrectomy group compared with the other 2 groups (which had very similar results). Gallbladder emptying was similar in the 3 groups. Sleeve gastrectomy patients showed the lowest ghrelin concentrations and higher early postprandial cholecystokinin and glucagon-like peptide 1 peaks than did the other participants. This group also showed an improved insulin resistance pattern compared with morbidly obese patients. CONCLUSIONS: Sleeve gastrectomy seems to be associated with profound changes in gastrointestinal physiology that contribute to reducing hunger and increasing sensations of satiation. These changes include accelerated gastric emptying, enhanced postprandial cholecystokinin and glucagon-like peptide 1 concentrations, and reduced ghrelin release, which together may help patients lose weight and improve their glucose metabolism after surgery. This trial was registered at clinicaltrials.gov as NCT02414893.

Hernioplastia inguinal electiva en pacientes con anticoagulación oral. ¿Son candidatos a cirugía ambulatoria? / Elective inguinal hernioplasty in patients on chronic anticoagulation therapy. Management and outcome

Introducción El tratamiento perioperatorio de los pacientes con anticoagulantes orales (ACO) incrementa la complejidad de la hernioplastia inguinal electiva. Objetivo Analizar la seguridad de nuestro protocolo de tratamiento en pacientes con ACO intervenidos de hernioplastia inguinal electiva y valorar el porcentaje de pacientes tratados mediante cirugía ambulatoria y cirugía de corta estancia. Material y métodos Se revisaron los datos administrativos de 1.184 pacientes intervenidos de hernioplastia inguinal en 2005 2007 y se identificó a 47 pacientes en tratamiento con ACO. Se utilizó, como tratamiento puente perioperatorio, un protocolo estandarizado con heparinas de bajo peso molecular (HBPM). Los resultados se analizaron hasta 30 días después del procedimiento e incluían las siguientes variables: hemorragia, episodios tromboembólicos o muerte y régimen hospitalario (cirugía mayor ambulatoria, corta estancia o ingreso convencional).Resultados La media de edad fue 74±10 años; 12 (25%) pacientes tenían un alto riesgo tromboembólico y 31 (67%) pacientes tenían la categoría ASA III. La técnica quirúrgica de elección fue la hernioplastia sin tensión con mallas de polipropileno. En 6 (13%) pacientes se diagnosticó hematoma de la herida quirúrgica y 1 (2,1%) paciente sufrió una hemorragia mayor que precisó de reintervención. Ningún paciente tuvo episodios tromboembólicos y no hubo fallecimientos. A 11 (23%) pacientes se trató de forma ambulatoria y a 16 (34%), en régimen de cirugía de corta estancia. La media de estancia hospitalaria fue 2,4±5,1 días. Conclusiones La hernioplastia inguinal electiva en pacientes con ACO, mediante una terapia puente con HBPM, es un procedimiento seguro. La anticoagulación oral no es una contraindicación absoluta para la cirugía ambulatoria (AU)

Background Perioperative management of patients on anticoagulant therapy increases the complexity of elective inguinal hernia repair. We assessed the safety of our standardised anticoagulation protocol and investigated the outpatient and one day surgery rates. Material and methods The records of 1184 patients undergoing elective inguinal hernioplasty between 2005 and 2007 were reviewed; 14 patients on chronic anticoagulation therapy were identified. We used a standard bridging therapy protocol with low-molecular-weight heparins. Outcomes were assessed at 30 days post-procedure and included bleeding, thromboembolic events or death and type of hospital admission. Results Mean age was 74±10 years; 12 (25%) patients were high risk for thromboembolism and 31 (67%) patients were ASA III. Almost all inguinal repairs were performed using a polypropylene mesh; 6 (13%) patients had a surgical site haematoma and there was 1 (2.7%) major bleeding, that was re-operated on. No thromboembolic events or deaths occurred; 11 (23%) patients were treated on an outpatient basis and 16 (34%) on a one day surgery regimen. Mean hospital stay was 2.4±5.1 days. Conclusions Elective inguinal hernioplasty in patients on chronic oral anticoagulation therapy using a standard bridging protocol is a safe procedure. Chronic anticoagulation therapy is not a contraindication for ambulatory surgery (AU)

Mil trasplantes hepáticos en el Hospital Clínic i Provincial de Barcelona / One thousand liver transplants in Hospital Clinic i Provincial de Barcelona (Spain)

Objetivo. El objetivo de este trabajo fue estudiar una serie de 1.000 trasplantes hepáticos (TH) y evaluar los cambios experimentados en el tiempo de los donantes y receptores utilizados, así como los resultados obtenidos. Material y método. Con el fin de evaluar las diferencias entre el inicio y la actualidad, se compararon los primeros 100 trasplantes (entre junio 1988 y junio de 1990) con los últimos 200 trasplantes (entre enero de 2001 y junio de 2003). Resultados. Destaca el aumento en la edad de los donantes (23 ± 10 frente a 45 ± 19), el cambio en la etiología de la muerte cerebral (traumatismo craneoencefálico: el 78 frente al 23,5%; accidente cerebrovascular: el 17 frente al 52,5%) y el mayor porcentaje de donantes procedentes de programas alternativos a la donación estándar de cadáver en el segundo período (donante vivo: 12,5%). Asimismo, el inicio de la técnica de Piggy-back y la realización de la anastomosis biliar sin tutorización. La supervivencia actuarial del paciente al año fue superior en el segundo período con respecto al primero (el 84 frente al 91,3%).El porcentaje de retrasplante total de toda la serie fue del 9,5%. La supervivencia actuarial del retrasplante fue a 1, 5 y 10 años del 67,7, 51,3 y 39,4%, respectivamente. Conclusión. La falta de donantes y el aumento de la lista de espera han hecho que aceptemos donantes de peor calidad, receptores en situaciones más críticas y que iniciemos programas alternativos e innovadores. Pese a ello, no se han alterado los buenos resultados alcanzados, debido a una mejoría del manejo del paciente antes, durante y después del trasplante (AU)

The aim of this study was to evaluate a consecutive series of 1000 liver transplants performed in our institution and to evaluate changes over time in donors and recipients, as well as results. Material and method. To clearly evaluate the differences between the initial transplantation period and the present period, the first 100 consecutive liver transplantations performed (June 1988-June 1990) and the last 200 consecutive liver transplantations performed (January 2001-June 2003) were compared. Results. Donor age increased (23±10 vs. 45±19), the etiology of brain death changed (severe head injury: 78% vs. 23.5%; stroke: 17% vs. 52.5%) and the percentage of donors from alternative methods to cadaveric donors increased (living donors: 12.5%) in the second period. Regarding recipients, the piggy-back technique and biliary anastomosis without T-tube were introduced in the second period. Actuarial 1-year survival was higher in the second period than in the first (84% vs. 91.3%). The need for retrasplantation in the entire series was 9.5%, with actuarial survival at 1, 5 and 10 years of 67.7%, 51.3% and 39.4%, respectively. Conclusion. Because of the lack of donors and the greater number of patients on the waiting list, poorer quality donors and more critical recipients have been accepted and alternative and innovative programs have been started. Nevertheless, due to improvement in patient management before, during and after transplantation, the previous good results have been maintained (AU)
