Role of Research Working Group (RWG) can expedite research progress by fostering collaboration between scientists, clinicians, and stakeholders. Benefits of a Global RWG include pooling resources and expertise to develop new research ideas, addressing disparities, and building local research capacity, with the potential to improve breast cancer research and outcomes.

Anterolateral Thoracotomy: A Novel and Simple Technique to Improve the Closure Using the Self Locking Knot.

Thoracotomy is defined as an incision made by the surgeon in the chest wall in order to allow visibility of the thoracic cavity content. This can be used by surgeons to treat thoracic cavity content diseases including the heart, lungs, esophagus, and other organs. Thoracic incision closure remains an item with no consensus. Therefore, we present an easy way and give a little tip for closure using the slipknot that will allow the correct approach of ribs and the successful closure of the intercostal space.

Translation, adaptation, and validation of the MeNTS score in colombian population: The MeNTS Col score.

Objective: To evaluate and validate the medically necessary and time sensitive score by testing the variables, in order to create a surgical preoperative score for procedure prioritization in COVID-19 pandemic in Colombia. Methods: A multicenter retrospective cross-sectional study of instrument validation with a cultural adaptation and translation into the Spanish language was carried out in Bogota, Colombia. Patients over 18 years of age who had undergone elective procedures of general surgery and subspecialties were included. The translation of the medically necessary and time sensitive score into Spanish was performed independently by two bilingual surgeons fluent in both English and Spanish. A final version of the Spanish questionnaire (MeNTS Col) for testing was then produced by an expert committee. After translation and cultural adaptation, it was submitted to evaluate the psychometric properties of the medically necessary and time sensitive score. Cronbach's α was used to represent and evaluate the internal consistency and assess reliability. Results: A total of 172 patients were included, with a median age of 54 years; of which 96 (55.8%) patients were females. The vast majority of patients were treated for general surgery (n = 60) and colon and rectal surgery (n = 31). The evaluation of the internal consistency of the scale items in Spanish version was measured, and values of 0.5 for 0.8 were obtained. In the reliability and validation process, Cronbach's α values in all items remained higher than 0.7. The new MeNTS Col model was analyzed, and a result of 0.91 was obtained. Conclusions: The Spanish version of the medically necessary and time sensitive, the MeNTS Col score, and its respective Spanish translation perform similarly to the original version. Therefore, they can be useful and reproducible in Latin American countries.

Single incision laparoscopic appendectomy with surgical-glove port is cost-effective and reliable in complicated acute appendicitis: A casecontrol multicenter study in Colombia.

Background: The single-port (SPL) and multi-port (MPL) laparoscopic approach are the gold standard of management of acute appendicitis, due to its multiple advantages over open surgery, mainly because of its direct effects on recovery, esthetics and costs of the procedure. However, in third-world countries, the laparoscopic approach is not yet fully reproducible due to the costs of the technique. The surgical-glove port single incision laparoscopic appendectomy (SGP-SILA) has been proposed as a viable option. However, it has never been studied in Colombia. Objective: To evaluate the cost-effectiveness and reliability of SGP-SILA in the management of complicated acute appendicitis, compared to traditional MPL approach. Materials and methods: A retrospective case control study was carried out comparing patients undergoing laparoscopic appendectomy by SGP-SILA vs. MPL, evaluating operating costs associated with intraoperative and postoperative variables in two tertiary centers in Bogota, Colombia. The data were analyzed and expressed according to their nature and distribution. Results: 116 patients were included (SGP-SILA: 62 and MPL: 54). The median surgical time for SGP-SILA was 60 min vs. 39 min for MPL. SGP-SILA was shown to cause lower frequency of surgical site infection (4 vs. 8 patients; p = 0.047). It was found a significant correlation between Grade III surgical site infection and surgery time (p = 0.047) in the MPL group; also, with hospital stay (p < 0.001). Also, a lower risk of surgical site infection was found with the SGP-SILA technique (22% vs. 31%). SGP-SILA generated a reduction in both direct and indirect operating costs of approximately 10% (616 USD vs. 683 USD). Conclusion: SGP-SILA and MPL are feasible and comparable procedures in the resolution of complicated acute appendicitis. SGP-SILA turns out to be more cost-effective compared to MPL, due to the use of more easily accessible instruments. This may be a reproducible technique in low- and middle-income countries.

Long-Term Outcomes of Laparoscopic Common Bile Duct Exploration Through Diathermy, Choledochotomy, and Primary Closure: A 6-Year Retrospective Cohort Study.

Background and Objective: Choledocholithiasis is a frequent pathology, unfortunately when its endoscopic management fails, there is no consensus of how it should be addressed. The aim of this study was to evaluate the safety, feasibility, and long-term outcomes of laparoscopic common bile duct exploration (LCBDE) using electrosurgery (coagulation) for choledochotomy followed by primary closure after endoscopic treatment failure. Materials and Methods: A retrospective cohort study of patients who underwent LCBDE from 2013 to 2018 was conducted in Bogotá, Colombia. Clinical demographics, operative outcomes, recurrence rate of common bile duct stones, and long-term bile duct complications were analyzed. A descriptive analysis was performed. Results: A total of 168 patients were analyzed. Most of the patients were males (53.37%) with a median age of 73 years with no comorbidities (65%). Stone clearance was successful in 167 patients (99.4%). Nonlethal complications were noted in 3 patients during the surgery or in the immediate postoperative (1.79%) and managed with T-tube or endoscopically. No cases of mortality surgery related were observed. There were no signs of any type of biliary injury or stricture observed in any of the patients during the 24-month follow-up period. Conclusions: LCBDE with diathermy and primary closure is a safe and effective treatment option for choledocholithiasis for failed endoscopic retrograde cholangiopancreatography in terms of long-term outcome as well as short-term outcome.

Impact on infectious outcomes during laparoscopic cholecystectomy with the use of home-made vs commercial gallbladder retrieval bag: a retrospective comparative study in a high-volume center.

BACKGROUND: Laparoscopic cholecystectomy (LC) is one of the most commonly performed emergency procedures, with approximately 600,000 patients undergoing the procedure every year in the United States. Although LC is associated with fewer complications when compared with open cholecystectomy, the risk for infectious complications, including surgical site infection and intra-abdominal abscess, remains a significant source of postoperative morbidity. The goal of this study is to determine whether the gallbladder retrieval technique during LC affects risk of infectious complications. METHODS AND PROCEDURES: We conducted a retrospective comparative study in a minimally invasive surgery high-volume center in Bogota, Colombia. Patients who underwent LC in 2018 to 2020 were identified. The patients were divided into three groups. One group of LC performed using home-made gallbladder retrieval bag (HMGRB), and another group of LC performed using commercial gallbladder retrieval bag (CGRB). The primary outcomes were infectious complications of superficial site infection and intra-abdominal abscess. RESULTS: A total of 68 (7.58%) patients underwent LC using an HMGRB, and 828 (92.41%) using a CGRB. There was no significant difference in preoperative sepsis, or sex distribution between patient groups. Using t test, we found differences on age distribution among groups (p < 0.01), surgical times (p < 0.01), and length of stay (p = 0.01). When using Chi square, we found differences in Tokyo and Parkland Grading Scale severity (p < 0.01), use of postoperative antibiotics (p < 0.01), and drain use (p < 0.01). Nonetheless, there was no difference in the rate of superficial surgical site infection (p = 0.92). CONCLUSION: HMGRB are not associated with increased risk of postoperative intra-abdominal abscess or superficial surgical site infection in comparison with CGRB but imply longer surgical times and length of stay. The use of HMGRB is safe, feasible, and has lower cost during LC.

Predictors for limb amputation in war vascular trauma: A 20-years retrospective analysis from the Colombian armed conflict.

BACKGROUND: The Latin American military vascular trauma is virtually unknown. The aim of this study was to describe severe war vascular trauma during the last 20 years of the Colombian armed conflict, and to identify predictors of limb amputation. METHODS: Retrospective analysis of a follow-up cohort from 1999 to 2019 of patients with associated severe vascular injuries (ISS >15) in the Colombian armed conflict treated at the Hospital Militar Central. RESULTS: Out of 5948 patients, 243 had military vascular trauma with 430 vascular injuries. The most frequent trauma mechanisms were gunshot wounds (n = 153; 63%). The most common injured vessels were femoral. 24 (10%) patients required amputations. Mortality was 4.1%. Amputation was associated with arteriovenous lesions (RR 4.82, p = 0.025), compartment syndrome (RR 4.2, p = 0.007), arteriovenous femoropopliteal injuries (RR 3.5, p = 0.0026), multiple arterial injuries (RR 3.35, p = 0.0218), associated fractures (RR 3.1, p = 0.0032). CONCLUSIONS: Concomitant arteriovenous injuries in popliteal and femoropopliteal lesions, multiple arterial lesions, bone fractures, and compartment syndrome are associated with amputation in severe vascular injury.

Surgical research in Colombia part 2: Scientific production of Colombian academic surgeons.

Introduction: The production of quality surgical evidence and the development of academic surgery have emerged as priorities for the solution of current barriers to achieving the objectives of global surgery. The academic training and scientific production of academic surgeons is essential for the production of new knowledge. In Latin America, specifically in Colombia, there are no studies that have analyzed this production. Methods: A retrospective cross-sectional bibliometric study was carried out, in which the Colombian Ministry of Science database was consulted with the validated results up to July 2021. In the search section for research profiles, the key word "Surgery" was used, and all associated CvLAC (profiles where the information of Colombian researchers can be found) and their registered products were reviewed. Results: A total of 1701 researchers in surgery were registered in the database of the Colombian Ministry of Science, of which only 380 corresponded to academic surgeons with correct registration. Only 6 (1.6%) were found to have a Ph.D., 45 (11.8%) a fellow, and 20 (5.3%) a master's degree. 79.5% (n = 302) of Colombian academic surgeons are men. Only 10.2% (n = 39) are formally categorized as researchers. 45.3% (n = 172) have not published scientific articles. The total number of published articles was 2386, and most of them were published in Q4 journals (n = 1121; 47%) or not indexed by SJR/Publindex (n = 517; 21.6%). Only 3 surgeons have more than 100 articles. 9.5% have published at least 1 book, and 40% have participated in at least 1 project. Conclusions: According to data registered with the Colombian Ministry of Science, a large part of the scientific production of Colombian academic surgeons is concentrated in scientific articles, most of which are found in Q4 or non-categorized journals. Approximately half of the academic surgeons have not published at least one scientific article. However, one fifth of those who have, have published at least 8 articles. Less than 20% of surgeons have additional postgraduate studies, and only 1 in 4 academic surgeons is a woman.

Laparoscopic Hartmann's reversal has better clinical outcomes compared to open surgery: An international multicenter cohort study involving 502 patients.

Background: Hartmann's procedure (HP) is used in surgical emergencies such as colonic perforation and colonic obstruction. "Temporary" colostomy performed during HP is not always reversed in part due to potential morbidity and mortality associated with reversal. There are several contributing factors for patients requiring a permanent colostomy following HP. Therefore, there is still some discussion about which technique to use. The aim of this study was to evaluate perioperative variables of patients undergoing Hartmann's reversal using a laparoscopic and open approach. Methods: The multicenter retrospective cohort study was done between January 2009 and December 2019 at 14 institutions globally. Patients who underwent Hartmann's reversal laparoscopic (LS) and open (OS) approaches were evaluated and compared. Sociodemographic, preoperative, intraoperative variables, and surgical outcomes were analyzed. The main outcomes evaluated were 30-day mortality, length of stay, complications, and postoperative outcomes. Results: Five hundred and two patients (264 in the LS and 238 in the OS group) were included. The most prevalent sex was male in 53.7%, the most common indication was complicated diverticular disease in 69.9%, and 85% were American Society of Anesthesiologist (ASA) II-III. Intraoperative complications were noted in 5.3% and 3.4% in the LS and OS groups, respectively. Small bowel injuries were the most common intraoperative injury in 8.3%, with a higher incidence in the OS group compared with the LS group (12.2% vs. 4.9%, p < 0.5). Inadvertent injuries were more common in the small bowel (3%) in the LS group. A total of 17.2% in the OS versus 13.3% in the LS group required intensive care unit (ICU) admission (p = 0.2). The most frequent postoperative complication was ileus (12.6% in OS vs. 9.8% in LS group, p = 0.4)). Reintervention was required mainly in the OS group (15.5% vs. 5.3% in LS group, p < 0.5); mortality rate was 1%. Conclusions: Laparoscopic Hartmann's reversal is safe and feasible, associated with superior clinical outcomes compared with open surgery.

First case report of gastric outlet obstruction due to aortofemoral bypass Dacron graft erosion of the duodenum treated with neo aortoiliac system procedure.

INTRODUCTION: Gastric outlet obstruction is an uncommon complication of surgical treatment of aortoiliac occlusive disease with aortofemoral bypass. The most frequent presenting feature of duodenal erosion due to aortic synthetic graft is upper gastrointestinal bleeding, which can range from a minor "herald" bleed to exsanguinating hemorrhage. CASE PRESENTATION: A 64-year-old male patient with an aortofemoral Dacron bypass due to aortoiliac occlusive disease TASC II D with a chronic graft infection required emergency resection of the right limb of the Dacron graft two years ago. The patient developed abdominal pain, postprandial vomiting and progressive weight loss with an upper gastrointestinal endoscopy that showed Dacron graft material eroding into the fourth portion of the duodenum generating a gastric outlet obstruction without aortoenteric fistula and ulceration in the duodenal mucosa. CLINICAL DISCUSSION: The treatment goals of aortoenteric fistula are to control hemorrhage, treat infection, maintain adequate distal perfusion, graft explantation and aortic reconstructions like in this case. Traditional treatment of aortoenteric fistula is graft excision and establishing an anatomic autologous or an extra-anatomic synthetic bypass. Neo aortoiliac system procedure has shown to be the most effective and safest emerging technique today. CONCLUSION: Aortoenteric fistula is a life-threatening condition associated with high morbidity and mortality and it can also pose a diagnostic dilemma. There are many presentations of aortoenteric fistula including gastric outlet obstruction syndrome. The neo aortoiliac system procedure is the ideal curative surgical approach in stable patients.

Metastasis of the abdominal wall in a patient with diagnosis of pulmonary adenocarcinoma: An interesting finding.

Tumors of the abdominal wall are rare, divided into benign and malignant lesions that are composed of primary tumors and by the parietal invasion of intra-abdominal tumors and metastatic parietal implants. In the case of metastases in the abdominal wall, the most frequent are metastases from neoplasms of colonic origin. The case described below is that of a 68-year-old patient with a history of stage IIA left lung adenocarcinoma who received partial response radiotherapy with an indication for chemotherapy, which she refused and lost follow-up.
