Open vs Minimally Invasive Approach for Emergent Colectomy in Perforated Diverticulitis.

BACKGROUND: Traditionally, perforated diverticulitis has been managed with an open approach, with a Hartmann procedure or a colectomy with primary anastomosis. Minimally invasive surgery is associated with postoperative advantages in the elective setting and may show a benefit in the emergent setting. OBJECTIVE: The aim of this study was to compare postoperative outcomes of open vs minimally invasive approaches for emergent perforated diverticulitis. DESIGN: This was a retrospective review of the American College of Surgeons National Surgical Quality Improvement Program targeted colectomy database using propensity score matching. SETTINGS: Interventions were performed in hospitals participating in the national database. PATIENTS: Patients who underwent emergent colectomy from 2012 to 2017 were included. Procedures were divided into Hartmann procedure and primary anastomosis. Open vs minimally invasive groups were defined by intention to treat. MAIN OUTCOME MEASURES: Outcomes measures included length of stay and overall morbidity and mortality. RESULTS: Of 130,616 patients, 7105 met inclusion criteria (4486 Hartmann procedure and 2619 primary anastomosis). A total of 1989 open Hartmann procedure cases were matched to 663 minimally invasive cases. The minimally invasive group underwent longer operations and had lower rates of respiratory failure. There were no differences in overall complications, mortality, length of stay, or home discharge. In the primary anastomosis group, 1027 cases were matched 1:1. The minimally invasive approach was associated with longer operative times, but reduced wound dehiscence, sepsis, bleeding, overall complications, and length of stay. No difference was detected in anastomotic leak, mortality, reoperation, or readmission rates. LIMITATIONS: Limitations include retrospective nature, data loss, nonuniformity, selection bias, and coding errors. CONCLUSIONS: Emergent minimally invasive primary anastomosis results in a shorter length of stay and decreased 30-day morbidity in comparison with open primary anastomosis for perforated diverticulitis. Emergent open and minimally invasive Hartmann procedures for perforated diverticulitis have comparable outcomes, perhaps because of a 40% conversion rate.

ABORDAJE ABIERTO VERSUS MNIMAMENTE INVASIVO PARA COLECTOMA DE EMERGENCIA EN DIVERTICULITIS PERFORADA: ANTECEDENTES:Tradicionalmente, la diverticulitis perforada se ha tratado con un abordaje abierto, con un procedimiento de Hartmann o una colectomía con anastomosis primaria. La cirugía mínimamente invasiva se asocia con ventajas posoperatorias en el escenario electivo y puede mostrar beneficio en el escenario emergente.OBJETIVO:El objetivo de este estudio fue comparar los resultados posoperatorios del abordaje abierto versus el mínimamente invasivo para la diverticulitis perforada emergente.DISEÑO:Ésta fue una revisión retrospectiva de la base de datos de colectomía dirigida del Programa Nacional de Mejoramiento de la Calidad Quirúrgica del Colegio Americano de Cirujanos utilizando el pareamiento por puntaje de propensión.ESCENARIO:Las intervenciones se realizaron en los hospitales participantes en la base de datos nacional.PACIENTES:Se incluyeron pacientes que fueron sometidos a colectomía emergente de 2012 a 2017. Los procedimientos se dividieron en procedimiento de Hartmann y anastomosis primaria. Los grupos abierto versus mínimamente invasivo se definieron por intención de tratar.PRINCIPALES MEDIDAS DE RESULTADO:Las medidas de resultado incluyeron la duración de la estancia, la morbilidad general y la mortalidad.RESULTADOS:De 130,616 pacientes, 7,105 cumplieron los criterios de inclusión (4,486 procedimiento de Hartmann y 2,619 anastomosis primaria). 1,989 casos abiertos de procedimientos de Hartmann se emparejaron con 663 casos mínimamente invasivos. El grupo mínimamente invasivo se sometió a operaciones más prolongadas y tuvo tasas más bajas de insuficiencia respiratoria. No hubo diferencias en las complicaciones generales, la mortalidad, la duración de la estancia o el alta domiciliaria. En el grupo de anastomosis primaria, 1,027 casos se emparejaron 1: 1. El abordaje mínimamente invasivo se asoció con tiempos quirúrgicos más prolongados, pero también con tasas reducidas de dehiscencia de herida, sepsis, sangrado, complicaciones generales y la duración de la estancia. No se detectaron diferencias en las tasas de fuga anastomótica, mortalidad, reintervención o reingreso.LIMITACIONES:Las limitaciones incluyen la naturaleza retrospectiva, pérdida de datos, falta de uniformidad, sesgo de selección y errores de codificación.CONCLUSIONES:La anastomosis primaria mínimamente invasiva emergente resulta en una estancia más corta y una disminución de la morbilidad a los 30 días en comparación con la anastomosis primaria abierta para la diverticulitis perforada. El procedimiento de Hartmann abierto y mínimamente invasivo de emergencia para la diverticulitis perforada tiene resultados comparables, quizás debido a una tasa de conversión del 40%.

Spontaneous Perforation of Anterior Choroidal Artery with Resultant Pseudoaneurysm Formation: Unusual Cause of Subarachnoid Hemorrhage.

BACKGROUND: Subarachnoid hemorrhage resulting from spontaneous perforation of a small intracranial vessel, with resultant pseudoaneurysm formation, has not been widely reported in the literature. CASE DESCRIPTION: We present the case of a 71-year-old patient with rupture of a small aneurysm of a duplicated left anterior choroidal artery causing an acute third nerve palsy. The aneurysm was not able to be treated endovascularly without sacrifice of the parent vessel. At surgery, a pseudoaneurysm was seen completely separate from the parent vessel, which was actively bleeding through a hole in the vessel. The pseudoaneurysm was indenting the oculomotor nerve. After confirmation of adequate collateral flow, the abnormal segment of vessel was trapped and the pseudoaneurysm removed with surrounding clot. The patient's cranial nerve palsy resolved. CONCLUSIONS: This case illustrates an unusual sequela of subarachnoid hemorrhage presenting a unique challenge in surgical management.

A Fish Mouth Appearing Perforation of the Native Aortic Valve Due to Streptococcus infantarius subspecies coli.

Infective endocarditis due to Streptococcus infantarius with the subspecies (subsp.) coli is infrequently encountered in healthy humans. This entity is associated with hepatobiliary malignancies and colorectal neoplasia. Here, we report on a unique case of endocarditis associated with S. infantarius subsp. coli in an 80-year-old male with no known risk factors of the infective endocarditis.

Epidemiology of Otitis Media with Spontaneous Perforation of the Tympanic Membrane in Young Children and Association with Bacterial Nasopharyngeal Carriage, Recurrences and Pneumococcal Vaccination in Catalonia, Spain - The Prospective HERMES Study.

The Epidemiology of otitis media with spontaneous perforation of the tympanic membrane and associated nasopharyngeal carriage of bacterial otopathogens was analysed in a county in Catalonia (Spain) with pneumococcal conjugate vaccines (PCVs) not included in the immunization programme at study time. A prospective, multicentre study was performed in 10 primary care centres and 2 hospitals (June 2011-June 2014), including all otherwise healthy children ≥2 months ≤8 years with otitis media presenting spontaneous tympanic perforation within 48h. Up to 521 otitis episodes in 487 children were included, showing by culture/PCR in middle ear fluid (MEF): Haemophilus influenzae [24.2%], both Streptococcus pneumoniae and H. influenzae [24.0%], S. pneumoniae [15.9%], Streptococcus pyogenes [13.6%], and Staphylococcus aureus [6.7%]. Culture-negative/PCR-positive otitis accounted for 31.3% (S. pneumoniae), 30.2% (H. influenzae) and 89.6% (mixed S. pneumoniae/H. influenzae infections). Overall, incidence decreased over the 3-year study period, with significant decreases in otitis by S. pneumoniae and by H. influenzae, but no decreases for mixed S. pneumoniae/H. influenzae infections. Concordance between species in nasopharynx and MEF was found in 58.3% of cases, with maximal rates for S. pyogenes (71.8%), and with identical pneumococcal serotype in 40.5% of cases. Most patients (66.6%) had past episodes. PCV13 serotypes were significantly more frequent in first episodes, in otitis by S. pneumoniae as single agent, and among MEF than nasopharyngeal isolates. All non-PCV13 serotypes separately accounted for <5% in MEF. Up to 73.9% children had received ≥1 dose of PCV, with lower carriage of PCV13 serotypes than among non-vaccinated children. Pooling pneumococcal isolates from MEF and nasopharynx, 30% were multidrug resistant, primarily belonging to serotypes 19A [29.8%], 24A [14.3%], 19F [8.3%] and 15A [6.0%]. Our results suggest that increasing PCV13 vaccination would further reduce transmission of PCV13 serotypes with special benefits for youngest children (with none or uncompleted vaccine schedules), preventing first otitis episodes and subsequent recurrences.

Unique Case of Pseudomembranous Aspergillus Tracheobronchitis: Tracheal Perforation and Horner's Syndrome.

Pseudomembranous aspergillus tracheobronchitis is an uncommon form of invasive pulmonary aspergillosis, and it is generally seen in immunocompromised patients. We report about a mildly immunocompromised case with pseudomembranous aspergillus tracheobronchitis, which caused tracheal perforation, and Horner's syndrome. A 44-year-old female with uncontrolled diabetes mellitus, complaining of fever and dyspnea, was admitted to the hospital. She was hospitalized with community-acquired pneumonia and diabetic ketoacidosis. Insulin infusion and empirical antibiotics were firstly commenced. Bronchoscopy showed left vocal cord paralysis with extensive whitish exudative membranes covering the trachea and the main bronchi. Liposomal amphotericin B was added due to the probability of fungal etiology. Mucosal biopsy revealed aspergillus species. Second bronchoscopic examination demonstrated a large perforation in the tracheobronchial system. Despite all treatments, respiratory failure developed on the 25th day and the patient died within 2 days. Pseudomembranous aspergillus tracheobronchitis is fatal in about 78 % of all cases despite appropriate therapy. Early diagnosis and efficient antifungal therapy may improve the prognosis.

Spontaneous colonic perforation: a rare complication of collagenous colitis.

Collagenous colitis is a clinicopathologic syndrome characterized by chronic watery diarrhea and unique histopathologic features. Spontaneous colonic perforation in the setting of collagenous colitis is a highly unusual complication, with only three cases reported in the literature to date. We present a fourth case and propose a potential pathologic mechanism for acute colonic perforation in this patient population.
