Gastric bypass - 10 years' results.

INTRODUCTION: Gastric bypass has not gained as much popularity in the Czech Republic as technically simpler restrictive bariatric procedures, frequently with a fading long-term effect. The aim of the presentation is to point out the long-term results after two types of gastric bypasses. METHOD: Retrospective analysis of prospectively collected data in an initial set of patients after laparoscopic RYGB (Roux Y gastric bypass) and OAGB/MGB (one anastomosis/mini gastric bypass) performed at Breclav Hospital in 2010-2013. Evaluation based on the BAROS system, according to weight development, comorbidities, psychological aspects, complications and reoperations. RESULTS: Data available for evaluation are from 32 patients out of a total of 60; the follow-up rate is 53%. The patients are lighter by 34 kg on average (0-64 kg); TBWL (total basic weight loss): 25.7%. The majority of operated diabetics are free of signs of diabetes, and all others have a reduced need for antidiabetic medication. Hypertension, sleep apnea and psychological assessment of life in 6 domains improved. Eight of the 32 followed patients underwent reoperation during 10 years; only 2 of these procedures were acute for complications (anastomotic ulceration), both in smokers; further elective reoperations included 2 conversions of OAGB/MGB to RYGB due to reflux, 2 corrective surgeries, and 2 procedures for a suspected internal hernia. There was no conversion from laparoscopic to open surgery, no peritonitis associated with a leak, and no mortality within 30 days. The BAROS score (5.56) indicates a "very good result" of the gastric bypasses after 10 years. CONCLUSION: Gastric bypasses are safe and provide a high and lasting metabolic effect that meets the general expectations of an invasive intervention that can fundamentally improve the quality of treatment for otherwise incurable chronic diseases related to adiposity (so-called ABCD), especially type 2 diabetes.

Clinical practice guidelines for perioperative care in bariatric surgery 2023: Adapted ERAS (enhanced recovery after surgery) guidelines with consensual voting of the working group of the Joint Bariatric and Metabolic Surgery Section of the Czech Surgery .

INTRODUCTION: Currently, bariatric surgery is the most effective treatment for the morbid obesity. It provides sustained weight loss as well as demonstrated positive effects on obesity-related comorbidities. The number of procedures performed worldwide has seen a sharp increase in the past twenty years. Therefore, an effort has been developed to establish a consensus in perioperative care based on best evidence. METHODS: The working group of the Joint Bariatric and Metabolic Surgery Section of the Czech Surgery Society and Czech Society of Obesitology prepared clinical practice guidelines for the ERAS (enhanced recovery after surgery) concept in perioperative care in bariatric surgery. The working group based its guidelines on ERAS guidelines published in 2021. The working group adopted the original text and then adapted the text and added its comments to specific items as appropriate. Electronic voting of all members of the working group was the final phase, by which the strength of consensus was expressed with respect to individual elements of the guidelines. RESULTS: The Czech working group reached a consensus with ERABS (enhanced recovery after bariatric surgery) guidelines for most elements. The quality of evidence is low for some interventions of the ERAS protocol for bariatric surgery. Therefore, extrapolation from other surgeries and fields is needed for evidence-based practice. CONCLUSION: The guidelines are intended for clinical practice in bariatric surgery with the ERAS protocol based on updated evidence and guidelines. It is based on recent and comprehensive ERAS guidelines adopted and adapted by the Czech working group of the Joint Bariatric and Metabolic Surgery Section of the Czech Surgery Society and Czech Society of Obesitology. Some supplementations and specifications are reflected in comments added to the Czech version.

Gastric bypass and its role in metabolic and bariatric surgery.

INTRODUCTION: Historically, gastric bypass (GB) has been the oldest procedure used in bariatric surgery. Even though technically demanding, it had been the most widely used method for decades worldwide and still holds an irreplaceable position for its pronounced and long-term metabolic effect as well as for the therapeutic effect in gastroesophageal reflux (GERD). METHOD: The authors retrospectively analyse a series of 268 cases of GB, focusing on short-term weight loss, the metabolic effect on type two diabetes (T2DM), complication and reoperation rates and the BAROS scoring system in Roux-en-Y bypass (RYGB) and in minigastric bypass with one anastomosis (MGB/OAGB), comparing both of them to more frequently used gastric plication and sleeve gastrectomy. RESULTS: Both GB, without any increase in complication and reoperation rates, lead to a higher weight loss and the best BAROS scoring in comparison to other, simpler restrictive procedures. One year after GB, resolution of T2DM is seen in most diabetes patients operated on, the number needed to treat being.

[10 years of sleeve gastrectomy in the Czech Republic in terms of the surgical procedure]. / 10 let sleeve gastrectomy - tubulizace zaludku v Ceské republice z hlediska operacního výkonu.

INTRODUCTION: Sleeve gastrectomy (SG) as a single bariatric/metabolic procedure has been performed since 2003 in the world, and since 2006 in the Czech Republic. We report 10 years experience with SG in the Czech Republic from 2006 to 2015. METHOD: Prospectively collected data from 14 surgical departments was evaluated retrospectively using descriptive statistics for every year from 2006 to 2015 and subsequently evaluated and compared for the entire period. The number of the patients, mean age, mean weight and BMI at the time of surgery, the number of patients with T2DM after SG, mean follow-up, mean %BMIL (% Body Mass Index Loss), distance of the starting point of the resection line from the pylorus, the size of the calibration bougie, the rate of complications, and the number and type of conversion procedures were evaluated. RESULTS: 4134 sleeve gastrectomies were done in the Czech Republic from 2006 to 2015 with the mean follow-up of 32.9 months (range 2145 months) from the procedure. The mean weight at the time of surgery fluctuated between 114.2 kg and 128.9 kg; mean BMI fluctuated between 42.3 and 46.7. Mean %BMIL was 63.2% for the entire evaluated period. The distance of the starting point of the resection line from the pylorus changed from the mean 6.1 cm (range 67 cm) to mean 4.2 cm (range 36 cm) and the size of the calibration bougie changed from the mean 39.2 F (range 3642 F) to mean 37.1 F (range 3542 F). As regards early postoperative complications, bleeding from the resection line occurred in 1.4% and a leak from the staple line occurred in 1.1%. The gastroesophageal reflux disease and hiatal hernia occurred in 17.3% as the most frequent late complications. Conversion to another bariatric procedure was approached in 3.8% in the event of an unsatisfactory effect of the SG. CONCLUSION: Bariatric or metabolic surgery, respectively, is a safe and effective surgical method for the treatment of severe obesity and T2DM in morbidly obese patients. Currently, SG is the most widely used bariatric/metabolic procedure in the Czech Republic as well as in most other countries and the long-time results are similar in comparison with other authors.Key words: bariatric surgery - sleeve gastrectomy - resection line - complications.

[Czech bariatry in 2010]. / Ceská bariatrie v roce 2010.

INTRODUCTION: It is only during the past two decades, when obesity has become to be considered a pandemic disorder. However, in 1953 Varco performed jejunoileal bypass as the world's first bariatric surgical procedure. 30 years later, Pesková performed the first bariatric surgery--a gastroplasty--in Czechoslovakia. From 1984 she started to perform fixed gastric bandages, through laparotomic app- roach at that time. The first laparoscopic fixed bandage in Czechoslovakia was performed in 1993. Over the years, the number of surgical procedures to treat morbid obesity, as well as the number of bariatric surgeons, continued to increase. In 2004, Czech Bariatric Section of the Czech Surgical Society and the Czech Society of Obesitology of the Czech Medical Association of J. E. Purkyne, were established. MATERIAL AND METHODS: 170 bariatric surgeries were performed in the Czech Republic in 1999. The majority of procedures included fixed gastric bandage, rarely, adjustable bandage was performed. At that time, bariatric procedures were performed at five sites only. However, over the past 10 years, bariatric surgery has largely developed in the Czech Republic. The exact number of bariatric procedures completed per year was unknown, therefore, 21 surgical clinics, at which bariatric procedures are performed, were contacted from January to June 2010. Heads of the clinics were asked to provide basic data on surgical treatment of obesity. The aim of the study was to analyze the situation in bariatric surgery in the Czech Republic at the end of 2009. A total of 18 clinics (85.8%) joined the study and provided their own statistical data. 14 of them perform over 20 bariatric procedures a year. RESULTS: The analysis data showed that, in 2009, a total of 1558 bariatric procedures were completed at 18 surgical clinics and approximately 1600 procedures were performed in the whole Czech Republic. However, out of the total, over 230 patients were foreigners. In 99% of bariatric procedures in morbid obese subjects, laparoscopic approach was used. CONCLUSION: Over the ten year period, the number of clinics performing over 20 bariatric procedures a year increased from five to 14 clinics and the number of bariatric procedures increased from 170 to 1600 procedures a year. It is 900% increase, compared to the year 1999! Nevertheless, compared to other countries, e.g. Austria, the number of bariatric procedures does not correspond with prevalence rates of obesity in the Czech Republic.

The use of oxidized regenerated cellulose (surgicel) in closing Schneiderian membrane tears during the sinus lift procedure / El uso de celulosa oxidada regenerada (Surgicel®) para cerrar las roturas de la membrana de Schneider durante el procedimiento quirúrgico del levantamiento del seno

During the sinus lift procedure, undesirable perforations of the Schneiderian membrane can occur in up to 58of cases. Several methods for their closing exist. This article presents a method of covering the perforation with a strip of oxidized regenerated cellulose (Surgicel). One or two layers of material swell after being saturated with blood, turning into a gelatinous mass and forming a tight and mechanically resistant seal. This simple method has been successfully tested on 223 perforations of the Schneiderian membrane that occurred over a period of 58 months.

Durante el procedimiento quirúrgico del levantamiento del seno, pueden producirse perforaciones indeseables de la membrana sinusal, hasta en el 58% de los casos. Existen varios métodos de cierre. Este artículo presenta un método para cubrir la perforación con una lámina de celulosa oxidada regenerada (Surgicel®). Una o dos capas del material se hinchan luego de ser saturadas con sangre, transformándose en una masa gelatinosa, y formando así un sello consistente y mecánicamente resistente. Este método simple ha sido probado con éxito en 223 perforaciones de la membrana de Schneider ocurridas en un período de 58 meses.

A six-year study of hydroxyapatite-coated root-form dental implants / Un estudio de seis años sobre implantes dentales de raíz con recubrimiento de hidroxiapatita

BACKGROUND: The effect of hydroxyapatite coating of dental implants is controversial. The long-term fate of hydroxyapatite-coated implants has been the subject of some criticism. PURPOSE: The aim of this retrospective study was to assess the clinical outcome of hydroxyapatite-coated cylindrical root-form endosseous Impladent dental implants (LASAK Ltd, Prague, Czech Republic) during a six-year course. METHODS: Three-hundred and ninety-one consecutively placed implants were used in 169 patients and followed for four to six years. Interval and cumulative success of implants and prostheses survival was tabulated. Marginal bone loss was measured RESULTS: Of the total number of implants, 98.5achieved initial osseointegration. The cumulative success was 98.3after one year, 97.0after three years, 92.8after five years and 90.4after six years. The prostheses survival at the end of the study was 100for fixed bridges totally supported by implants, 96.5for fixed bridges with combined implant and tooth support, 94.2for single crowns, 90.9for mandibular overdentures and 81.3for maxillary overdentures. Marginal bone loss averaged 2.4 +/- 0.8 mm at the end of five years. CONCLUSION: The success rate of the investigated hydroxyapatite-coated implants was comparable with the data presented in the literature and with the results of the similar implants without hydroxyapatite-coating. However, the marginal bone loss was of interest. Longer monitoring of the implants is necessary.

ANTECEDENTES: El efecto del recubrimiento de los implantes dentales con hidroxiapatita es un asunto controversial. El destino a largo plazo de los implantes recubiertos con hidroxiapatita ha sido objeto de críticas. PROPÓSITO: El objetivo de este estudio retrospectivo fue evaluar los resultados clínicos de los implantes dentales endo-óseos de raíz con recubrimiento de hidroxiapatita de la marca Impladent (LASAK Ltd., Praga, República Checa), durante el transcurso de seis años. MÉTODOS: Un número de 391 implantes colocados consecutivamente, fueron usados en 169 pacientes, y sujetos a seguimiento por un período de 4 a 6 años. Se tabuló el éxito de lo implantes – por intervalos y de forma cumulativa – así como la supervivencia de las prótesis. Se midió la pérdida de hueso marginal. RESULTADOS: El 98.5% de los implantes alcanzó óseo-integración en la fase inicial. El éxito cumulativo fue de 98.3% después de un año, 97.0% después de tres años, 92.8% luego de cinco años, y 90.4% tras seis años. La supervivencia de las prótesis al final del estudio fue de 100% para puentes fijos soportados totalmente por implantes, 96.5% para puentes fijos con combinación de soporte sobre dientes e implantes, 94.2% para coronas solas, 90.9% para sobredentaduras mandibulares, y 81.3% para sobredentaduras maxilares. La pérdida marginal de hueso tuvo un promedio de 2.4 ± 0.8 mm al final de los cinco años.CONCLUSIÓN: La tasa de éxito de los implantes recubiertos con HA investigados, resultó comparable a los datos presentados en la literatura, y a los resultados de implantes similares sin revestimiento de HA. Sin embargo, la pérdida marginal de hueso fue una alerta: se necesita monitorear los implantes por un período más largo de tiempo.

Tumors of the rectum and anus.

Within a ten year period we have performed 433 radical operations on the rectum. An anterior resection of rectum was done in 110 cases, low anterior resection in 60 patients, very low anterior resection was done by stapler in 32 patients and was sewn by hand in 10 patients. Colo-anal anastomoses were performed 86 times and abdominoperineal amputation of rectum sec. Miles 20 times. Local transsphincteric procedures were used 14 times. In 12 patients the colo-anal anastomosis was performed either for recurrence of tumor or after a Hartmann's procedure. In the carcinoma of the lower half of the rectum there is still an unsolved question: whether to perform a low or a very deep low anastomosis or whether an extirpation of rectum with sparing the sphincters and sewing a colo-anal anastomosis is more beneficial. In the years 1980-1995 we treated surgically 64 patients with a tumor in anal area. All patient underwent preoperative radio- and chemotherapy. In our group adenocarcinoma was demonstrated in 6 patients, squamous carcinoma in 48 patients and squamous cells of the carcinoma in situ in 10 patients.

[Laparoscopy in abdominal injuries]. / Laparoskopia pri úrazoch brucha.

Application of laparoscopy in trauma was studied in Traumatological Hospital in Brno, within a more widely concipated project of grant IGA, Ministry of Health in Czech Republic. In the series of 28 patients there was detected neither a single complication, nor a reoperation nor any significant damage to the patient in connection with the use of the endoscopic method detected. Results of the research and author's observations act as a guide for use of more precise indication criteria and adequate selection of patients and for the proper evaluation of the method. Provided that basic principles and priorities of the urgencies management are kept, the application of this minimally invasive method in the management of patients with selected both the blunt and the penetrating abdominal trauma is justified, including associated extraabdominal injuries and polytrauma. It's diagnostic contribution exceeds the therapeutic one.

[Laparoscopic inguinal hernioplasty--results in the initial group 2 years after surgery]. / Laparoskopická inguinální hernioplastika--výsledky v iniciálním souboru dva roky po operaci.

The authors evaluate retrospectively after a two-year interval the results of laparoscopic inguinal hernioplasty (L.I.H.) in an initial group of 49 patients (52 hernias) operated by three surgeons using the method of transabdominal preperitoneal plastic operation (TAPP) in 1993, 1994 and 1995. They confirmed the expected favourable results, except for the very high incidence of relapses (6.7%). In view of the small number of patients other conclusions cannot be drawn except analyse the three early failures of L.I.H., indicate technical mistakes made when introducing the new operation and emphasize the necessity to adhere to the known basic technical details when performing this relatively pretentious laparoscopic operation.

[Trauma and emergency thoracoscopy]. / Trauma a casná torakoskopie.

Authors present their first experience with urgent videothoracoscopy in polytraumatism and in isolated thoracic trauma patients. During the prospective study in 1993-1995 thoracoscopically was treated 41 (18%) from 229 multiple trauma patients including thorax trauma, hospitalised in our Institute. Thoracoscopy underwent 62 (4%) from 1452 patients with simple thoracic trauma. Thoracoscopy has been indicated above all for continued bleeding into peritoneal cavity, for suspected diafragmatic injury and for the diagnosis and treatment of posttraumatic complications. Authors suggest that thoracoscopy is in experienced hands and adequatelly equipped workplaces an accurate and safe method for the diagnosis and in some cases also for therapy of hemodynamic stabile patients with thoracic trauma.

[Injuries of organs in the abdominal and retroperitoneal cavities]. / Poranení orgánu brisní dutiny a retroperitonea.

In the Traumatological Hospital Brno approx. 100 polytraumatised patients yearly are admitted with involvement of 2, 3 or 4 systems. During the period of years 1982-1991 authors operated 308 injured patients with increasing haemoperitoneum, 254 patients with profuse bleeding into retroperitoneum, 77 patients with traumatic perforative peritonitis and 61 patients with severe thoracoabdominal trauma. Mortality in this group was 26%. Authors evaluate the contribution of new diagnostic methods for the indication of early surgical treatment, and results of operations, complications and problems.
