The role of RObotic surgery in EMergency setting (ROEM): protocol for a multicentre, observational, prospective international study on the use of robotic platform in emergency surgery.

BACKGROUND: Robotic surgery has gained widespread acceptance in elective interventions, yet its role in emergency procedures remains underexplored. While the 2021 WSES position paper discussed limited studies on the application of robotics in emergency general surgery, it recommended strict patient selection, adequate training, and improved platform accessibility. This prospective study aims to define the role of robotic surgery in emergency settings, evaluating intraoperative and postoperative outcomes and assessing its feasibility and safety. METHODS: The ROEM study is an observational, prospective, multicentre, international analysis of clinically stable adult patients undergoing robotic surgery for emergency treatment of acute pathologies including diverticulitis, cholecystitis, and obstructed hernias. Data collection includes patient demographics and intervention details. Furthermore, data relating to the operating theatre team and the surgical instruments used will be collected in order to conduct a cost analysis. The study plans to enrol at least 500 patients from 50 participating centres, with each centre having a local lead and collaborators. All data will be collected and stored online through a secure server running the Research Electronic Data Capture (REDCap) web application. Ethical considerations and data governance will be paramount, requiring local ethical committee approvals from participating centres. DISCUSSION: Current literature and expert consensus suggest the feasibility of robotic surgery in emergencies with proper support. However, challenges include staff training, scheduling conflicts with elective surgeries, and increased costs. The ROEM study seeks to contribute valuable data on the safety, feasibility, and cost-effectiveness of robotic surgery in emergency settings, focusing on specific pathologies. Previous studies on cholecystitis, abdominal hernias, and diverticulitis provide insights into the benefits and challenges of robotic approaches. It is necessary to identify patient populations that benefit most from robotic emergency surgery to optimize outcomes and justify costs.

Concomitant Sigmoid Diverticulitis and Periampullary Duodenal Diverticulitis Complicated by Lemmel Syndrome: A Case Report.

Diverticular disease is a major cause of hospitalizations, especially in the elderly. Although diverticulosis and its complications predominately affect the colon, the formation of diverticula in the small intestine, most commonly in the duodenum, is well characterized in the literature. Although small bowel diverticula are typically asymptomatic, and diagnosed incidentally, a complication of periampullary duodenal diverticulum is Lemmel syndrome. Lemmel syndrome is an extremely rare condition whereby periampullary duodenal diverticula, most commonly without diverticulitis, leads to obstruction of the common bile duct due to mass effect and associated complications including acute cholangitis and pancreatitis. Here, we present the first case, to our knowledge, of periampullary duodenal diverticulitis complicated by Lemmel syndrome with concomitant colonic diverticulitis with colovesical fistula. Our case and literature review emphasizes that Lemmel syndrome can present with or without suggestions of obstructive jaundice and can most often be managed conservatively if caught early, except in the setting of emergent complications.

Does surgery improve quality of life in patients with ongoing- or recurrent diverticulitis; a systematic review and meta-analysis.

BACKGROUND: Recurrences or persistent symptoms after an initial episode of diverticulitis are common, yet surgical treatment is rarely performed. Current guidelines lack clear recommendations on whether or not to operate, even though recent studies suggest an improved quality of life following surgery. The aim of this study is therefore to compare quality of life in patients with recurrent or ongoing diverticulitis treated conservatively versus surgically, giving a more definitive answer to the question of whether or not to operate on these patients. METHODS: A systematic literature search was conducted in EMBASE, MEDLINE and Cochrane. Only comparative studies reporting on quality of life were included. Statistical analysis included calculation of weighted mean differences and pooled odds ratios. RESULTS: Five studies were included; two RCT's and three retrospective observational studies. Compared to conservative treatment, the SF-36 scores were higher in the surgically treated group at each follow-up moment but only the difference in SF-36 physical scores at six months follow-up was statistically significant (MD 6.02, 95%CI 2.62-9.42). GIQLI scores were also higher in the surgical group with a MD of 14.01 (95%CI 8.15-19.87) at six months follow-up and 7.42 (95%CI 1.23-12.85) at last available follow-up. Also, at last available follow-up, significantly fewer recurrences occurred in the surgery group (OR 0.10, 95%CI 0.05-0.23, p < 0.001). CONCLUSION: Although surgery for recurrent diverticulitis is not without risk, it might improve long-term quality of life in patients suffering from recurrent- or ongoing diverticulitis when compared to conservative treatment. Therefore, it should be considered in this patient group.

Management of Diverticulitis: A Review.

Importance: Care of patients with diverticulitis is undergoing a paradigm shift. This narrative review summarizes the current evidence for left-sided uncomplicated and complicated diverticulitis. The latest pathophysiology, advances in diagnosis, and prevention strategies are also reviewed. Observations: Treatment is moving to the outpatient setting, physicians are forgoing antibiotics for uncomplicated disease, and the decision for elective surgery for diverticulitis has become preference sensitive. Furthermore, the most current data guiding surgical management of diverticulitis include the adoption of new minimally invasive and robot-assisted techniques. Conclusions and Relevance: This review provides an updated summary of the best practices in the management of diverticulitis to guide colorectal and general surgeons in their treatment of patients with this common disease.

Pneumoperitoneum, pneumoretroperitoneum and pneumomediastinum: rare complications of perforation peritonitis: a case report.

BACKGROUND: Gas extravasation complications arising from perforated diverticulitis are common but manifestations such as pneumoperitoneum, pneumoretroperitoneum, and pneumomediastinum happening at the same time are exceedingly rare. This case report explores the unique presentation of these 3 complications occurring simultaneously, their diagnosis and their management, emphasizing the importance of interdisciplinary collaboration for accurate diagnosis and effective management. CASE PRESENTATION: A 74-year-old North African female, with a medical history including hypertension, dyslipidemia, type 2 diabetes, goiter, prior cholecystectomy, and bilateral total knee replacement, presented with sudden-onset pelvic pain, chronic constipation, and rectal bleeding. Clinical examination revealed hemodynamic instability, hypoxemia, and diffuse tenderness. After appropriate fluid resuscitation with norepinephrine and saline serum, the patient was stable enough to undergo computed tomography scan. Emergency computed tomography scan confirmed perforated diverticulitis at the rectosigmoid junction, accompanied by the unprecedented presence of pneumoperitoneum, pneumoretroperitoneum, and pneumomediastinum. The patient underwent prompt surgical intervention with colo-rectal resection and a Hartmann colostomy. The postoperative course was favorable, leading to discharge one week after admission. CONCLUSIONS: This case report highlights the clinical novelty of gas extravasation complications in perforated diverticulitis. The unique triad of pneumoperitoneum, pneumoretroperitoneum, and pneumomediastinum in a 74-year-old female underscores the diagnostic challenges and the importance of advanced imaging techniques. The successful collaboration between radiologists and surgeons facilitated a timely and accurate diagnosis, enabling a minimally invasive surgical approach. This case contributes to the understanding of atypical presentations of diverticulitis and emphasizes the significance of interdisciplinary teamwork in managing such rare manifestations.

Primary anastomosis with diverting loop ileostomy vs. Hartmann's procedure for acute diverticulitis: what happens after discharge? Results of a nationwide analysis.

BACKGROUND: Current guidelines recommend resection with primary anastomosis with diverting loop ileostomy over Hartmann's procedure if deemed safe for acute diverticulitis. The primary objective of the current study was to compare the utilization of these strategies and describe nationwide ostomy closure patterns and readmission outcomes within 1 year of discharge. METHODS: This was a retrospective, population-based, cohort study of United States Hospitals reporting to the Nationwide Readmissions Database from January 2011 to December 2019. There were 35,774 patients identified undergoing non-elective primary anastomosis with diverting loop ileostomy or Hartmann's procedure for acute diverticulitis. Rates of ostomy closure, unplanned readmissions, and complications were compared. Cox proportional hazards and logistic regression models were used to control for patient and hospital-level confounders as well as severity of disease. RESULTS: Of the 35,774 patients identified, 93.5% underwent Hartmann's procedure. Half (47.2%) were aged 46-65 years, 50.8% female, 41.2% publicly insured, and 91.7% underwent open surgery. Primary anastomosis was associated with higher rates of 1-year ostomy closure (83.6% vs. 53.4%, p < 0.001) and shorter time-to-closure [median 72 days (Interquartile range 49-103) vs. 115 (86-160); p < 0.001]. Primary anastomosis was associated with increased unplanned readmissions [Hazard Ratio = 2.83 (95% Confidence Interval 2.83-3.37); p < 0.001], but fewer complications upon stoma closure [Odds Ratio 0.51 (95% 0.42-0.63); p < 0.001]. There were no differences in complications between primary anastomosis and Hartmann's procedure during index admission [Odds Ratio = 1.13 (95% Confidence Interval 0.96-1.33); p = 0.137]. CONCLUSION: Patients who undergo primary anastomosis for acute diverticulitis are more likely to undergo ostomy reversal and experience fewer postoperative complications upon stoma reversal. These data support the current national guidelines that recommend primary anastomosis in appropriate cases of acute diverticulitis requiring operative treatment.

Acute diverticulitis of the appendix.

Acute diverticulitis of the appendix (ADA), though uncommon, often presents similarly to acute appendicitis but carries a higher risk of complications such as perforation and malignancy. We report the case of a male patient in his 50s with acute right iliac fossa abdominal pain, diagnosed via CT scan with ADA. Urgent laparoscopic appendicectomy was performed, and the patient was discharged without further issues. This case highlights the importance of promptly identifying and managing such conditions to minimise complications and improve outcomes. Despite the overlap in symptoms between appendiceal diverticulitis and acute appendicitis, accurate diagnosis is crucial for appropriate treatment. Healthcare providers should maintain a high index of suspicion, particularly in older patients presenting with an acute appendicitis, like clinical picture to ensure timely intervention and optimal patient care.

Gut microbiome composition and metabolic activity in women with diverticulitis.

The etiopathogenesis of diverticulitis, among the most common gastrointestinal diagnoses, remains largely unknown. By leveraging stool collected within a large prospective cohort, we performed shotgun metagenomic sequencing and untargeted metabolomics profiling among 121 women diagnosed with diverticulitis requiring antibiotics or hospitalizations (cases), matched to 121 women without diverticulitis (controls) according to age and race. Overall microbial community structure and metabolomic profiles differed in diverticulitis cases compared to controls, including enrichment of pro-inflammatory Ruminococcus gnavus, 1,7-dimethyluric acid, and histidine-related metabolites, and depletion of butyrate-producing bacteria and anti-inflammatory ceramides. Through integrated multi-omic analysis, we detected covarying microbial and metabolic features, such as Bilophila wadsworthia and bile acids, specific to diverticulitis. Additionally, we observed that microbial composition modulated the protective association between a prudent fiber-rich diet and diverticulitis. Our findings offer insights into the perturbations in inflammation-related microbial and metabolic signatures associated with diverticulitis, supporting the potential of microbial-based diagnostics and therapeutic targets.

Non-malignant left colon emergency surgery: evaluation of factors affecting clinical outcomes and complications.

BACKGROUND: Emergency colorectal resections hold a significant position in general surgical practice, and pathologies of the left colon are relatively common. This study was conducted to assess the outcomes of isolated left colon surgeries with benign etiologies, drawing on clinicopathological and biochemical data. METHODS: We carried out a retrospective review and statistical analysis of demographic, clinical, and laboratory data of patients who underwent left colon surgery at the general surgery clinic of a tertiary care hospital, excluding those with malignancy-related emergencies, from January 2017 to January 2022. RESULTS: The average age of the 48 patients in the study was 56.9±16.4 years. Complicated acute diverticulitis was the most frequent indication for emergency surgery (n=19, 39.6%). The Hartmann procedure was the surgical technique most often employed (n=30, 62.5%). The rates of postoperative morbidity and mortality within 30 days were 27.1% and 8.3%, respectively. Increased postoperative morbidity was linked to advanced age (mean 65.4±15.8 vs. 53.8±15.7, p=0.028), the preoperative administration of vasopressors, lower platelet counts, hypoalbuminemia (<3 mg/dl), and azotemia (blood urea nitrogen >20 mg/dl). There was no statistically significant correlation between comorbidities, American Society of Anesthesiologists (ASA) scores, surgical methods, or other clinical data and postoperative outcomes. CONCLUSION: For emergency colorectal surgery pertaining to left colon pathologies, it is critical to conduct a comprehensive evaluation in the perioperative period, especially for elderly and hypotensive patients with renal function abnormalities and for those requiring vasopressors.

Recurrence of severe diverticulitis is associated with age and birth decade.

BACKGROUND: The risk of recurrence is an important consideration when deciding to treat patients medically or with elective colectomy after recovery from diverticulitis. It is unclear whether age is associated with recurrence. This study aimed to examine the relationship between age and the risk of recurrent diverticulitis while considering important epidemiologic factors, such as birth decade. METHODS: The Utah Population Database was used to identify individuals with incident severe diverticulitis, defined as requiring an emergency department visit or hospitalization, between 1998 and 2018. This study measured the relationship between age and recurrent severe diverticulitis after adjusting for birth decade and other important variables, such as sex, urban/rural status, complicated diverticulitis, and body mass index using a Cox proportional hazards model. RESULTS: The cohort included 8606 individuals with a median age of 61 years at index diverticulitis diagnosis. After adjustment, among individuals born in the same birth decade, increasing age at diverticulitis onset was associated with an increased risk of recurrent diverticulitis (hazard ratio [HR] for 10 years, 1.8; 95% CI, 1.5-2.1). Among individuals with the same age of onset, those born in a more recent birth decade were also at greater risk of recurrent diverticulitis (HR, 1.9; 95% CI, 1.6-2.3). CONCLUSION: Among individuals with an index episode of severe diverticulitis, recurrence was associated with increasing age and more recent birth decade. Clinicians may wish to employ age-specific strategies when counseling patients regarding treatment options after a diverticulitis diagnosis.

Systematic review and meta-analysis of the management of acute uncomplicated diverticulitis: time to change traditional practice.

BACKGROUND: To evaluate comparative outcomes of outpatient (OP) versus inpatient (IP) treatment and antibiotics (ABX) versus no antibiotics (NABX) approach in the treatment of uncomplicated (Hinchey grade 1a) acute diverticulitis. METHODS: A systematic online search was conducted using electronic databases. Comparative studies of OP versus IP treatment and ABX versus NABX approach in the treatment of Hinchey grade 1a acute diverticulitis were included. Primary outcome was recurrence of diverticulitis. Emergency and elective surgical resections, development of complicated diverticulitis, mortality rate, and length of hospital stay were the other evaluated secondary outcome parameters. RESULTS: The literature search identified twelve studies (n = 3,875) comparing NABX (n = 2,008) versus ABX (n = 1,867). The NABX group showed a lower disease recurrence rate and shorter length of hospital stay compared with the ABX group (P = 0.01) and (P = 0.004). No significant difference was observed in emergency resections (P = 0.33), elective resections (P = 0.73), development of complicated diverticulitis (P = 0.65), hospital re-admissions (P = 0.65) and 30-day mortality rate (P = 0.91). Twelve studies (n = 2,286) compared OP (n = 1,021) versus IP (n = 1,265) management of uncomplicated acute diverticulitis. The two groups were comparable for the following outcomes: treatment failure (P = 0.10), emergency surgical resection (P = 0.40), elective resection (P = 0.30), disease recurrence (P = 0.22), and mortality rate (P = 0.61). CONCLUSION: Observation-only treatment is feasible and safe in selected clinically stable patients with uncomplicated acute diverticulitis (Hinchey 1a classification). It may provide better outcomes including decreased length of hospital stay. Moreover, the OP approach in treating patients with Hinchey 1a acute diverticulitis is comparable to IP management. Future high-quality randomised controlled studies are needed to understand the outcomes of the NABX approach used in an OP setting in managing patients with uncomplicated acute diverticulitis.

Current Management of Diverticulitis.

Diverticulosis and diverticulitis remain common diagnoses in western countries, and the incidence continues to rise. Diverticulitis accounts for roughly one-third of admissions to acute care hospitals annually, with even more patients being treated as outpatients due to improved understanding of risk stratification and the natural history of disease progression. Thus, having a thorough understanding of the etiology of the disease in conjunction with computed tomography findings and patient presentation can help dictate the appropriate treatment.

Resultados de una encuesta nacional sobre el manejo de los pacientes diagnosticados de diverticulitis aguda no complicada / Results of a national survey about the management of patients with acute uncomplicated diverticulitis

Introducción: El manejo de los pacientes diagnosticados de diverticulitis aguda no complicada ha evolucionado en los últimos años, y según diversas guías clínicas internacionales actuales, el tratamiento ambulatorio y sin antibioterapia puede ser utilizado en pacientes seleccionados. El objetivo de este estudio es evaluar la adhesión de los distintos centros nacionales a estas y otras recomendaciones en esta enfermedad. Métodos: Se realizó una encuesta online a nivel nacional que se dio a conocer a través de diversas aplicaciones informáticas y se analizaron estadísticamente los resultados obtenidos. Resultados: Participaron 104 cirujanos, representando 69 centros hospitalarios nacionales. En el 82,6% de los centros, se realiza manejo ambulatorio de los pacientes diagnosticados de diverticulitis aguda no complicada. El 23,2% de los centros tiene implantado un protocolo de tratamiento sin antibioterapia en pacientes seleccionados, mientras que en los centros que no siguen estas recomendaciones, las razones principales son las dificultades logísticas para su desarrollo (49,3%) y la ausencia de evidencia actual para ello (44,8%). Se han encontrado diferencias estadísticamente significativas al comparar la implantación de dichos protocolos entre centros con unidades acreditadas avanzadas y aquellas que no, con mayores tasas de manejo ambulatorio y sin antibioterapia en los centros acreditados avanzados (p≤0,05). Conclusiones: A pesar de ser una enfermedad muy frecuente, existe mucha heterogeneidad en su tratamiento a nivel nacional, por lo que sería recomendable la unificación de criterios diagnósticos y de tratamiento mediante la colaboración de las sociedades científicas y la simplificación de la puesta en marcha de protocolos hospitalarios.(AU)

Introduction: Management of patients diagnosed of acute uncomplicated diverticulitis has evolved lately and according to the latest guidelines, outpatient treatment and management without antibiotherapy may be used in selected patients. The aim of this study is to evaluate the adhesion among national centres to these and others recommendations related to this pathology. Methods: An online national survey, that has been broadcast by several applications, was performed. The results obtained were statistically analysed. Results: A total of 104 surgeons participated, representing 69 national hospitals. Of those, in 82.6% of the centers, outpatient management is performed for acute uncomplicated diverticulitis. 23.2% of the hospitals have a protocol stablished for treatment without antibiotherapy in selected patients. Centers that do not follow these protocols allege that the mean reasons are the logistic difficulties to set them up (49.3%) and the lack of current evidence for it (44.8%). Significative statistical differences have been found when comparing the establishment of such protocols between centers with advanced accredited units and those who are not, with higher rates of outpatient management and treatment without antibiotics in accredited units (P≤.05). Conclusions: In spite that this a very common disease, there is a huge national heterogeneity in its treatment. This is why it would adviseable to unify diagnostic and treatment criteria by the collaboration of scientific societies and the simplification of the development of hospitalary protocols.(AU)

Episodic Abdominal Pain-An Unexpected Cause for a Common Clinical Problem.

A previously healthy 55-year-old male patient presented repeatedly to the emergency department with severe episodic periumbilical abdominal pain. After an extensive diagnostic work-up and subsequent clinical deterioration, appendiceal diverticulitis was diagnosed. We identified a correlation of white blood cell counts and possibly faecal calprotectin with the clinical presentation. We suggest that appendiceal diverticulitis should be considered in middle-aged patients with recurrent episodes of abdominal pain that correlate with laboratory markers of inflammation.

Right-sided colonic diverticulitis. Short and long-term surgical outcomes and 2-year quality of life.

AIM: We aimed to investigate the short and the long-term outcomes and 2-year Quality of Life (QoL) of patients with right-sided colonic diverticulitis (RCD) surgically managed. METHOD: We conducted an ambidirectional cohort study of patients with RCD undergoing surgery between 2012/2022. A colonoscopy was performed at 1-year post surgery. The enrolled patients completed the EuroQoL (EQ-5D-3L) during a regular follow-up visit at 12 and 24 months after surgery. RESULTS: Three hundred nineteen patients with RCD were selected: 223 (70%) patients were treated by non-operative management (NOM) while 33 underwent surgery. Acute diverticulitis occurred in 30 patients: 9 (27.2%) were classified by CT as uncomplicated and 21 (63.6%) as complicated diverticulitis. Additionally, chronic diverticulitis occurred in 3 cases (9.2%). Specifically, 27 patients were classified by CT as 1a (81.8%) and 6 patients as 3 (18.2%). Right hemicolectomy was performed in 30 patients (90.8%), and ileo-caecectomy in 3 (9.2%). Nine (27.27%) experienced postoperative complications: 7 (77.7%) were classified according to the Clavien-Dindo as grade I-II, and 2 (22.2%) as grade III. No disease recurrence or colorectal cancer (CRC) was detected on colonoscopy. Thirty (90.8%) patients completed the 24-month follow-up. A statistically significant difference between preoperative and 24-month QoL index values (median 0.72; IQR = 0.57-0.8 vs. median 0.9; IQR = 0.82-1; p = 0.0003) was observed. CONCLUSIONS: The study results demonstrate satisfactory surgical outcomes and a better QoL after surgery. No disease recurrence or CRC was observed at colonoscopy 1 year after surgery.

Short- and long-term outcomes of acute diverticulitis in patients with transplanted kidneys.

AIM: The safety of nonoperative treatment for patients with transplanted kidneys who develop acute diverticulitis is unclear. Our primary aim was to examine the long-term sequelae of nonoperative management in this group. METHOD: We performed a population-based retrospective cohort study using linked administrative databases housed at ICES in Ontario, Canada. We included adult (≥18 years) patients admitted with acute diverticulitis between April 2002 and December 2019. Patients with a functioning kidney transplant were compared with those without a transplant. The primary outcome was failure of conservative management (operation, drainage procedure or death due to acute diverticulitis) beyond 30 days. The cumulative incidence function and a Fine-Grey subdistribution hazard model were used to evaluate this outcome accounting for competing risks. RESULTS: We examined 165 patients with transplanted kidneys and 74 095 without. Patients with transplanted kidneys were managed conservatively 81% of the time at the index event versus 86% in nontransplant patients. Short-term outcomes were comparable, but cumulative failure of conservative management at 5 years occurred in 5.6% (95% CI 2.3%-11.1%) of patients with transplanted kidneys versus 2.1% (95% CI 2.0%-2.3%) in those without. Readmission for acute diverticulitis was also higher in transplanted patients at 5 years at 16.7% (95% CI 10.1%-24.7%) versus 11.6% (95% CI 11.3%-11.9%). Adjusted analyses showed increased failure of conservative management [subdistribution hazard ratio (sHR) 3.24, 95% CI 1.69-6.22] and readmissions (sHR 1.55, 95% CI 1.02-2.36) for patients with transplanted kidneys. CONCLUSION: Most patients with transplanted kidneys are managed conservatively for acute diverticulitis. Although long-term readmission and failure of conservative management is higher for this group than the nontransplant population, serious outcomes are infrequent, substantiating the safety of this approach.

Divertículo de Meckel complicado. Experiencia de 15 años en un hospital interzonal / Complicated Meckel's diverticulum. Fifteen years of experiencein an interzonal hospital in the Province of Buenos Aires

Introducción: el divertículo de Meckel es la anomalía congénita más frecuente del tracto gastrointestinal. Puede presentarse con hemorragia, obstrucción intestinal o diverticulitis, complicaciones que disminuyen con la edad, por lo que en el adulto el diagnóstico suele ser incidental. El tratamiento de las complicaciones es quirúrgico, mediante diverticulectomía o resección segmentaria del intestino delgado, dependiendo de sus características morfológicas. Objetivo: analizar nuestra experiencia en el manejo del divertículo de Meckel complicado en un período de 15 años. Diseño: estudio descriptivo, observacional, transversal, retrospectivo. Material y métodos: se revisaron las historias clínicas de los pacientes operados por divertículo de Meckel complicado en el Servicio de Cirugía General del Hospital San Roque durante el periodo 2007-2022. Se registraron datos demográficos, presentación clínica, diagnóstico preoperatorio, tratamiento quirúrgico, complicaciones postoperatorias y hallazgos histopatológicos. Resultados: se incluyeron 25 pacientes, 21 (84%) hombres, 3 menores de 18 años. La presentación clínica fue un síndrome de fosa iliaca derecha en el 80% de los casos, obstrucción intestinal en el 16% y hemorragia en el 4%. En solo 2 casos se realizó el diagnóstico preoperatorio, confirmado mediante tomografía computada. Se realizó diverticulectomía en el 68% de los pacientes y resección segmentaria el 32%. El abordaje fue laparotómico en el 64%, principalmente en el periodo inicial y laparoscópico en el 36%. Hubo una complicación IIIb de Clavien-Dindo en un paciente pediátrico tratado con drenaje percutáneo. En un solo paciente (4%), que se presentó con hemorragia digestiva masiva, se encontró epitelio de tipo gástrico y páncreas ectópico en el divertículo. Conclusiones: En nuestra experiencia el divertículo de Meckel complicado se presentó predominantemente en hombres. La complicación más frecuente en el adulto fue la diverticulitis. El diagnóstico preoperatorio fue infrecuente y realizado por tomografía computada. La diverticulectomía es suficiente en la mayoría de los casos. Actualmente, la laparoscopia es una herramienta segura, rentable y eficiente que permite el diagnóstico y tratamiento oportunos de esta entidad. (AU)

Introduction: Meckel's diverticulum is the most common congenital malformation of the gastrointestinal tract. It can present with bleeding, intesti-nal obstruction or diverticulitis, complications that decrease with age, so in adults the diagnosis is usually incidental. Treatment of complications is surgical, through diverticulectomy or segmental resection of the small intestine, depending on its morphological characteristics. Objective: to analyze our experience in the management of complicated Meckel's diverticulum over a period of 15 years. Design: descriptive, observational, cross-sectional, retrospective study. Materials and methods: the medical records of patients operated on for complicated Meckel's diverticulum in the General Surgery Service of the San Roque Hospital during the period 2007-2022 were reviewed. Demo-graphic data, clinical presentation, preoperative diagnosis, surgical treatment, postoperative complications, and histopathological findings were recorded. Results: twenty-five patients were included, 21 (84%) men, 3 under 18 years of age. The clinical presentation was a right iliac fossa syndrome in 80% of cases, intestinal obstruction in 16% and hemorrhage in 4%. In only 2 cases was the preoperative diagnosis made, confirmed by computed tomography. Diverticulectomy was performed in 68% of patients and segmental resection in 32%. The approach was by laparotomy in 64%, mainly in the initial period, and by laparoscopy in 36%. There was a Clavien-Dindo IIIb complication in a pediatric patient treated with percutaneous drain-age. In only one patient (4%), who presented with massive gastrointestinal bleeding, gastric-type epithelium and ectopic pancreas were found in the diverticulum. Conclusions: In our experience, complicated Meckel's diverticulum occurred predominantly in men. The most frequent complication in adults was diverticulitis. Preoperative diagnosis was infrequent and was made by computed tomography. Diverticulectomy is sufficient in most cases. Currently, laparoscopy is a safe, profitable and efficient tool that allows for the timely diagnosis and treatment of this entity. (AU)

Acute Colonic Diverticulitis.

Acute colonic diverticulitis is a gastrointestinal condition that is frequently encountered by primary care and emergency department practitioners, hospitalists, surgeons, and gastroenterologists. Clinical presentation ranges from mild abdominal pain to peritonitis with sepsis. It is often diagnosed on the basis of clinical features alone, but imaging is necessary in more severe presentations to rule out such complications as abscess and perforation. Treatment depends on the severity of the presentation, the presence of complications, and underlying comorbid conditions. Medical and surgical treatment algorithms are evolving. This article provides an evidence-based, clinically relevant overview of the epidemiology, diagnosis, and treatment of acute diverticulitis.
