RESUMO

Background: Until now, working with others has been shaped by a style where 1 person made the main decisions at the top of the hierarchical pyramid. These days this one-directional model no longer makes sense. That is why we need to change to a collaborative style. Methods: An overview on the change in our surgical work and definitions on the collaborative work, coaching, and teamwork will be discussed and analyzed. Results and Discussion: The system is defined by the boundaries that we set; they can often be the type of activity to be carried out or the way it is achieved. Collaboration means accompanying processes with a clear idea of what needs to be achieved and what values need to be followed. In work contexts that are globalized, diverse, virtual, and made up of highly educated specialists, isolation and a lack of collaboration are common. We would like to highlight four of them: (1) Signature relationship practices: The importance of building relationships on the basis of "who I am," not "what I am." (2) Ambidextrous leadership: Collaborative work needs to concentrate first on the task and on performing it effectively. (3) Mentoring versus "tit-for-tat culture": Collaborative work helps the design of individual and team identities. (4) Training in relationship skills: for communication and conflict resolution. Conclusions: Working on relationship building conversations generates a systemic view that allows the creation of a communication context that facilitates collaborative work. They are all key skills to achieve a collaborative culture on work.

RESUMO

Background: Online education is not new. Their main options are talks, videos, and virtual courses. The quality and quantity of talks, together with the level of the speakers, is variable and heterogeneous. The arrival of the COVID-19 pandemic accelerated this process. The objective of this study was to analyze the result of a questionnaire on the current state of online education. Methods: Retrospective descriptive observational study based on a questionnaire. The participants consulted were Latin American physicians with different specialties. Results: A total of n = 361 participants were recruited. 26.9% had between 6 and 15 years of work experience. 63.1% carried out teleconsultation with their patients, and 96.1% attended between 1 and 10 talks/courses/webinar during the pandemic, whereas 1.6% did not attend any. "Talks" given received a rating of "Very Good" by 51.2%, and a 59.5% considered that the "Hybrid" option would be the best modality for future medical congresses in the postpandemic era. 84.7% considered that other possibilities of online teaching and online surgical training should be explored. Conclusion: Online education has marked the way of transmitting knowledge in recent years. It has been well accepted by those attending academic meetings.

RESUMO

Background: Gastrostomy is a widely used procedure that aims to obtain access to the stomach. Its purpose may be feeding or gastric decompression. Currently, the most common techniques are endoscopic and radiologic. Sometimes, these accesses are not available due to technical or patient-specific factors. In these cases, laparoscopic and percutaneous approaches combined could be an option. The aim of this study was to describe a laparoscopic-percutaneous combined gastrostomy procedure, feasibility, and complications. Materials and Methods: Retrospective descriptive observational study. All patients underwent laparoscopic-percutaneous combined gastrostomy required for feeding or decompressive gastrostomy. We analyzed variables: demographics, surgical indication, operation time, hospitalization stay, success, and morbidity/mortality associated to the procedure. Results: A total of n = 17 patients were recruited (58.8% women and 41.2% men), with mean age of 53. Regarding the indications of laparoscopic-percutaneous combined gastrostomy, 47% were due to upper gastrointestinal/head and neck tumor, 29.4% stomach location in a retrocostal position, 17.7% colonic interposition, and 5.9% acute gastric dilation of remnant after Roux-en-Y gastric bypass. The mean time of the procedure was 25 minutes, and mean hospitalization stay was 1.2 days. The success of the procedure was 100%. No complications and mortality associated with the procedure were reported. Conclusion: Laparoscopic-percutaneous combined gastrostomy is fast, feasible, safe, and cost effective. It is an option in patients where it is not possible to perform standard minimally invasive approaches.

RESUMO

Introducción: La colecistitis aguda es una patología quirúrgica común. Su resolución ideal es a través de la colecistectomía. En ocasiones, no es posible el abordaje quirúrgico, tomando protagonismo la colecistostomía percutánea. El objetivo de este trabajo fue analizar los resultados de la colecistostomía percutánea y de la colecistectomía quirúrgica en pacientes con colecistitis aguda. Material y Métodos: Se diseñó una revisión de trabajos clínicos que realizaron colecistostomías percutáneas y/o colecistectomías quirúrgicas en pacientes críticos con colecistitis aguda litiásica y/o alitiásica. Resultados: La búsqueda bibliográfica arrojó 12 artículos, de los cuáles se excluyeron 8 y se analizaron 4. De los artículos revisados, se reunieron 11374 pacientes con colecistitis (litiásica: 84,6% vs. alitiásica: 15,4%) analizando sus datos epidemiológicos. En el 21,4% de los casos se realizó colecistostomía percutánea y en el 78,6% colecistectomía quirúrgica. La morbilidad y mortalidad de los procedimientos percutáneos fue 11% y 9,8%, mientras que la de los procedimientos quirúrgicos fue 17,2% y 5,4%, respectivamente. El promedio de días de hospitalización fue 15.3 y 15.5, respectivamente. Conclusión: La colecistostomía percutánea presentó menor morbilidad, aunque reportó una mayor mortalidad. No hubo diferencias con respecto a la estadía hospitalaria. Los procedimientos percutáneos fueron menos costosos.

Introduction: Acute cholecystitis is a common surgical pathology. Its ideal resolution is through cholecystectomy. On occasions, a surgical approach is not possible, with percutaneous cholecystostomy taking center stage. The objective of this work was to analyze the results of percutaneous cholecystostomy and surgical cholecystectomy in patients with acute cholecystitis. Methods: A review of clinical studies that performed percutaneous cholecystostomies and / or surgical cholecystectomies in critically ill patients with acute lithiasic and / or alithiasic cholecystitis was designed. Results: The bibliographic search yielded 12 articles, of which 8 were excluded and 4 were analyzed. Of the articles reviewed, 11,374 patients with cholecystitis (lithiasic: 84.6% vs. alithiasic: 15.4%) were collected, analyzing their data epidemiological. Percutaneous cholecystostomy was performed in 21.4% of the cases and surgical cholecystectomy in 78.6%. The morbidity and mortality of percutaneous procedures was 11% and 9.8%, while that of surgical procedures was 17.2% and 5.4%, respectively. The average days of hospitalization were 15.3 and 15.5, respectively. Conclusion: Percutaneous cholecystostomy presented lower morbidity, although it reported higher mortality. There were no differences regarding hospital stay. Percutaneous procedures were less expensive.

RESUMO

Background: Obesity treatment requires surgical procedures included in bariatric surgery. Bleeding complications are reported in 1%-4%. Image-guided surgery (IGS) includes minimally invasive procedures that have the advantage of less aggression to the patient, fewer complications, and a quick recovery. Endovascular therapy by interventional radiology (IR) is a minimally invasive image-guided procedure widely used in central, peripheral, and splanchnic vascular pathology. Treatment of postoperative bleeding in bariatric surgery can be aided by image-guided endovascular procedures. Objectives: The aim of this study is to carry out an update on the application of IR in bariatric surgery bleeding complications. Bleeding Complications: General rate of postoperative complications in bariatric surgery is 0%-10%. Postoperative bleeding (1%-4%) can be gastrointestinal (endoscopic treatment) or intra-abdominal (surgical treatment/relaparoscopy). In the case of arterial vascular lesions that cannot be resolved either endoscopically or surgically, the option of endovascular treatment with IR should be considered. Conclusions: Endovascular approach through IR and IGS in bleeding complications after bariatric surgery is presented as a valid minimally invasive therapy option in this group of patients.

RESUMO

Background: Malignant or benign biliary obstructions can be successfully managed with minimally invasive percutaneous interventions. Since percutaneous approaches are challenging, extensive training using relevant models is fundamental to improve the proficiency of percutaneous physicians. The aim of this experimental study was to develop an in vivo training model in pigs to simulate bile duct dilatation to be used during percutaneous biliary interventions. Materials and Methods: Twenty-eight large white pigs were involved and procedures were performed in an experimental hybrid operating room. Under general anesthesia, animals underwent a preoperative magnetic resonance cholangiography (MRC). Afterward, the common bile duct was isolated and ligated laparoscopically. A postoperative MRC was performed 72 hours after the procedure to evaluate bile duct dilatation. The In vivo models presenting an effective dilatation model were included in the hands-on part of a percutaneous surgery training course. Animals were euthanized at the end of the training session. Results: Postoperative MRC confirmed the presence of bile duct dilatation in the survival pigs (n = 25). No intraoperative complications occurred and mean operative time was 15.8 ± 5.27 minutes. During the course, 27 trainees could effectively perform percutaneous transhepatic cholangiography, bile duct drainage, biliary duct dilatation, and stent placement, with a > 90% success rate, thereby validating the experimental model. All animals survived during the training procedures and complications occurred in 28.3% of cases. Conclusion: The creation of an in vivo bile duct dilatation animal model is feasible with a low short-term mortality. It provides a realistic and meaningful training model in percutaneous biliary procedures.

RESUMO

Background: Bariatric surgery is an effective treatment for obesity and its associated morbidities. They are safe surgeries, their general complication rate is 0%-10%. However, acute gastric dilation is an unusual complication. It requires rapid diagnosis and treatment to avoid major complications. Image-guided surgery represents a group of minimally invasive procedures. Acute gastric dilation is a complication that can benefit from the application of this type of procedure. We present a report of patients with acute gastric dilation of the remnant as a complication after bariatric surgery, its resolution through image-guided surgery, and updating. Materials and Methods: A retrospective review of patients who presented postoperative complications after bariatric surgery was carried out. The time period was 10 years. All patients were operated on in a single center by the same surgical team. Results: A total of 3507 bariatric procedures were analyzed (sleeve gastrectomy, 1929-55.1% ± 0.49%; Roux-en-Y gastric bypass [RYGB], 1403-40% ± 0.48%; other techniques, 175-4.9% ± 0.21%). The RYGB branch reported a total of 11 (0.78% ± 0.08%) complications, of which 2 (0.14% ± 0.03%) were reported as acute gastric dilation of the remnant. Conclusions: Acute gastric dilation of the post-RYGB remnant is a rare complication, but it can be serious. It is necessary to have a high suspicion to obtain an early diagnosis and treatment. Percutaneous gastrostomy is an image-guided procedure that can solve the problem temporarily or permanently.

RESUMO

Background: The relationship between obesity with common bile duct stone (CBDS) is close and increases after a Roux-en-Y gastric bypass (RYGB). Due to the anatomical modification, direct endoscopic access is not always possible. For this reason, image-guided surgery (IGS) by percutaneous transhepatic biliary drainage (PTBD) of the common bile duct (CBD) could be a first-line approach for the treatment of post-RYGB choledocholithiasis. The aim of this study was to analyze the feasibility and safety of CBDS treatment after RYGB with IGS. Materials and Methods: We present a descriptive retrospective observational multicentric study on the treatment of choledocholithiasis in patients operated on for RYGB using IGS through a minimally invasive approach by PTBD. The diagnosis of CBDS was made according to the symptoms of the patients, supported by blood tests, and medical images. Treatment was planned in two stages: in the first step, a PTBD was performed, and in the second step the choledocholithiasis was removed. Results: Of a total of 1403 post-RYGB patients, 21 presented choledocholithiasis. Of these, n = 18 were included. Symptoms were reported in n = 15 (8 cholestatic jaundice, 7 cholangitis), whereas n = 3 were asymptomatic. Percutaneous treatment was performed in all these patients, treated with a balloon and stone basket. A hyperamylasemia without pancreatitis was observed in 3 patients. No complications or deaths associated with the procedure were reported. The average hospital stay was 8.6 days. Conclusion: IGS is an interesting option for the treatment CBDS after RYGB. For these patients, PTBD is feasible and safe.

RESUMO

Background: Benign biliary strictures (BBS) befall in ∼7%-23% after hepaticojejunostomy and in 0.3%-0.6% after cholecystectomies. Their treatment options include surgical, endoscopic, and percutaneous management. The percutaneous approach is an excellent mini-invasive option including balloon dilation, biodegradable stents, and sustained dilation, a procedure born endoscopically. However, when the endoscopic approach fails or it is not available, it is possible to perform it percutaneously. Aim: To estimate the technical and clinical success of sustained percutaneous dilation with multiple catheters (SPDMC) in hepaticojejunostomy strictures and the percentage of complications and recurrence. Materials and Methods: We conducted a retrospective study, from a prospective database from January 2010 to March 2019, of 17 patients with postoperative BBS who failed to percutaneous pneumatic balloon dilation and underwent SPDMC with a mean follow-up of 2 years. Results: Seventeen patients between 28 and 71 years of age underwent SPMDC with technical success of 100%; the average number of catheters used was 5.59 (95% confidence interval [CI] 5.12-6.06) achieving a dilatation diameter of 16.15 mm (95% CI 14.71-17.60), and the therapeutic success rate was 71%, with recurrences of stricture and complications of 29% and 18%, respectively. The mean time with SPMDC was 7.06 months (95% CI 5.56-8.56). The median follow-up after dilation was 16 months, with an average of 27.75 months (95% CI 14.15-41.34). Conclusion: SPMDC is a feasible technique with a high technical success rate, therapeutic success rate, and low morbidity and mortality.
