Lymphogranuloma venereum: an unusual cause of rectal stenosis.

Lymphogranuloma Venereum (LGV) is a notifiable disease linked to high-risk sexual practices such as cruising, chemsex, or orgies. The anorectal manifestation is associated with receptive anal sex and presents with characteristic symptoms such as proctitis, tenesmus, suppuration, and in advanced cases, anorectal fistulas or stenosis. The case of a 57-year-old man engaging in high-risk sexual practices is presented, showing symptoms such as discharge, fistulizations, rectal stenosis, and a weight loss of 15 kg. Following diagnostic studies, a neoplastic and inflammatory origin was ruled out, confirming the LGV diagnosis. Although the patient responded positively to a three-week course of doxycycline, the stenosis persisted, ultimately necessitating a terminal colostomy. The patient was scheduled to undergo a protectomy to control the inflammatory and infectious process, a procedure that took place months later without significant incidents. The primary treatment for LGV continues to be doxycycline. In cases of complications, such as fistulas, abscesses, or stenosis, surgical interventions, drainage, or pneumatic dilations may be necessary.

Mucinous adenocarcinoma arising from complex perianal fistula: a diagnostic and therapeutic challenge.

We present a case of a 64-year-old male with a history of perianal abscesses that have been surgically treated on 10 occasions. Eight months after the last drainage procedure, he presented with a new abscess. Drainage was performed, revealing a cavity with smooth walls, a chronic appearance, filled with mucoid material. An internal fistulous opening was identified at the 6 o'clock position above the anorectal line, which communicated with the described cavity, forming a trans-sphincteric fistula to the mid-anal canal. Biopsy with pathological anatomy showed a mucinous adenocarcinoma with possible intestinal origin (CK20+, CDX2+, TTF1-, CK7+). After completing the evaluation, he was diagnosed with T4N1M0 rectal neoplasia. A diverting colostomy was performed, followed by neoadjuvant therapy, and subsequently, a laparoscopic abdominoperineal amputation. Pathological anatomy revealed residual adenocarcinoma ypT2N0 N0V0L0, R0. This case is notable for both the rarity of a mucinous adenocarcinoma originating in a perianal fistula and the nonspecific clinical presentation of such tumors. Clinical suspicion is crucial, especially in cases of recurrent abscesses with the discharge of mucoid material through fistulous openings, prompting the need for biopsies to ensure proper diagnosis and subsequent optimal treatment.

Recommendations from Latinx Trans and Non-Binary Individuals to Promote Cancer Prevention in Puerto Rico and Florida.

Latinx trans and non-binary individuals (LTNB) face increased cancer-related health disparities. Studies evidence how barriers at the individual, provider and organizational levels drive cancer disparities among LTNB individuals. These barriers increase the emotional discomfort associated with testing and disengagement from cancer prevention efforts. Moreover, there are no guidelines or interventions that address cancer prevention specifically among LTNB individuals. There is a need to develop interventions informed by the LTNB communities to promote cancer prevention and screening. The study aims to describe the recommendations provided by LTNB individuals to foster cancer screening and prevention in the communities residing in Puerto Rico and Florida. We conducted two online focus groups with a total of 15 LTNB participants. Participants were recruited using non-probabilistic purposive sampling. We used rapid-qualitative analysis for data interpretation. Findings are gathered in three main themes: (1) recommendations for promoting cancer prevention screening among providers; (2) specific recommendations to promote cancer screening among LTBN individuals; and (3) recommendations on delivery formats to foster cancer prevention. These results evidence the need and feasibility of developing community informed tailored interventions targeting cancer screening and preventative care to reduce cancer-related health disparities among the LTNB population.

Prostate gland metastasis as a late relapse of rectal adenocarcinoma.

We present a case report of a 49 year old patient with a known history of rectal adenocarcinoma treated with extended abdominal perineal resection. After five the patient was diagnosed with metastases to the prostate gland. This case stands out not only due to the infrequency of an onset of a colorectal tumor in the prostatic gland but also the late onset of the tumor. In these cases the differential diagnosis between a metastatic tumor and a primary urologic tumor is difficult due to similar morphology and histology, making the CDX-2 immunohistochemical maker expression an important tool to define the histopathology of the tumor.

Cervical ultrasound for the evaluation of the vocal cords: A pilot study in an endocrine surgery unit.

INTRODUCTION: Cervical ultrasound (CE) has emerged as a promising tool in recent years for vocal cord (VC) assessment in patients undergoing thyroid surgery. Our aim is to assess the reliability of CE once implemented in an endocrine surgery unit and performed by the surgeons themselves. MATERIAL AND METHOD: 86 participants with no history of laryngeal pathology or cervical surgery underwent CE by three independent endocrine surgeons. Laryngeal structures and specifically the VCs were analysed. To consider the examination as diagnostic, the VCs had to be visualised statically and during phonation. The time taken to perform the technique and the interobserver variability were also analysed. RESULTS: Of the 86 participants, 51.2% were male with a mean age of 43 years. The range of diagnostic examinations between surgeons was 60-68%, with substantial agreement between the 3 explorers (Fleiss's K-value = .714). Male sex and advanced age were factors associated with non-assessability of the technique. The mean procedure time was 72 s. CONCLUSIONS: CE is a fast, non-invasive, feasible bedside tool useful for the assessment of VCs prior to thyroid surgery, mainly in young women.

Obstructive jaundice secondary to a pseudoaneurysm of the superior mesenteric artery.

Superior mesenteric arteries pseudoaneurysms are rare entity, usually asymptomatic but they can appear as an abdominal pain, throbbing mass or shock, being jaundice an exceptional type of presentation. Diagnosis is made by imaging tests (CT) and currently the endovascular approach is the most widespread, reserving open surgery in selected cases. We describe the case of a patient with an 86mm SMA pseudoaneurysm with compression of the extrahepatic bile duct.

Sigmoid colon Schwannoma simulating colon cancer.

Schwannomas tumours are uncommonly developed in the gastrointestinal tract (2-6%), located in 12% of cases in small and large intestines. An 87-year-old woman was studied due to epigastric pain and dyspepsia. CT scan and colonoscopy showed a neoplastic process in the sigmoid colon. It was performed an oncologic laparoscopic sigmoidectomy. Histological study described a schwannoma and a positive immunohistochemistry to S-100. The diagnostic challenge is that this is a submucosa lesion, therefore, endoscopy biopsy is realized only in the mucosa. This becomes the differential diagnostic very difficult in order to differentiate from another mesenchymal tumor (GIST or leiomyoma). The immunohistochemistry helps in the diagnostic if it is positive to S- 100 and negative to C-KIT, CD-34, actine and desmine (findings of GIST tumors and leiomyoma). In conclusion, schwannoma diagnostic is tough. Those are asymptomatic tumors with nonspecific radiological findings. Diagnostic confirmation is a S-100 positive immunohistochemistry in the histological study.

Cytomegalovirus colitis seems to be colon cancer. HIV debut.

Cytomegalovirus (CMV) infection is very common in immunosuppressed patients. It can y puede afectar a todo el tracto gastrointestinal, presentándose como úlceras o pseudotumores. A 43-year-old male with no personal background of interest, was studied due to constitutional syndrome. The diagnosis was neoplasia of the right colon, reported by colonoscopy and CT scan. A right hemicolectomy was performed with oncologic character. The definitive histology was CMV infectious colitis with positive immunohistochemical staining. Treatment with ganciclovir was started and the patient was diagnosed with HIV infection. The unusual finding of CMV infection as a pseudotumor can simulate, clinically and radiologically, a colonic neoplasm. It has been described in the literature in patients immunocompromised by HIV; however, the absence of risk factors means that it can be confused with a primary neoformative process.

Linfoma de Hodgkin anal primario y tumor neuroendocrino intestinal sincrónicos: a propósito de un caso y revisión de la literatura / Primary rectal Hodgkin's lymphoma and synchronous small bowel neuroendocrine tumor: Case report and literature review

Resumen La localización extranodal gastrointestinal del linfoma de Hodgkin comprende el 5% de todos los linfomas. Dentro de este grupo, el linfoma anal primario representa menos del 0,05%, siendo por tanto una entidad extremadamente rara. Por otro lado, los tumores neuroendocrinos son un grupo heterogéneo de neoplasias relativamente poco frecuentes, pero de localización fundamentalmente digestiva. La asociación entre un linfoma de Hodgkin de localización anal y un tumor neuroendocrino intestinal no ha sido descrita previamente en la literatura, pero no es en absoluto raro que los tumores neuroendocrinos puedan coexistir con otro tipo de neoplasias. Los autores presentan el caso infrecuente de presentación de linfoma Hodgkin de localización anal asociado a un tumor neuroendocrino intestinal en una paciente mujer de 74 años, describiéndose la clínica, resultados de pruebas complementarias y tratamiento recibido.

Abstract Extranodal gastrointestinal Hodgkin's lymphoma comprises 5% of all lymphomas. In this group, primary rectal lymphoma represents less than 0.05%; thus, it is an extremely rare entity. On the other hand, neuroendocrine tumors are a heterogeneous group of infrequent neoplasms, mainly of digestive location. The association between a rectal Hodgkin's lymphoma and an intestinal neuroendocrine tumor has not been previously described in the literature, but it is not at all uncommon for neuroendocrine tumors to coexist with other types of neoplasms. The authors present a rare case of rectal Hodgkin's lymphoma associated with an intestinal neuroendocrine tumor in a 74-year-old female patient, describing the symptoms, complementary test results, and treatment.

Predictors of mortality in patients with rib fractures.

BACKGROUND: The aim of this study was to identify risk factors for morbidity and mortality in patients with rib fractures with focus on identifying a more exact age-dependent cut-off for increased morbidity and mortality. METHODS: Retrospective study of patients 16 years or older with rib fractures from blunt trauma. EXCLUSION CRITERIA: patients undergoing rib plating. Initial chest X-ray and Computed Tomography (CT) scans were re-read for the number of rib fractures (NRF) and presence of pulmonary contusion (PC). Data included demographics, mechanism of injury (MOI), NRF, associated injuries, Injury Severity Score (ISS), Glasgow Coma Scale (GCS), Geriatric Trauma Outcome Score (GTOS), presence of pneumothorax, hemothorax, hemo-pneumothorax, PC, Adult Respiratory Distress Syndrome (ARDS), pulmonary complications (ventilator-associated pneumonia, nosocomial pneumonia), and mortality. PC was quantified from CT scans with Mimics. Continuous data were analyzed using Student's t test. Variables significantly different by univariate analysis were analyzed by logistic regression analysis. RESULTS: The study group consisted of 1188 adult trauma patients admitted during a 2-year period; 800 males and 388 females, with a mean age of 54 ± 21. MOI: MVC, 735 (61.8%); falls, 364 (30.6%); other: 89. Mean NRF, 4 ± 2; GCS, GTOS, and ISS, 15 (15-15), 101 (82-124), and 19 ± 9, respectively. Incidence of PC was 329 (27.7%); PTX, HTX, and HTX/PTX, 264 (20.2%), 57 (4.8%), and 147 (12.4%). Flail chest, in 17 (1.4%); 321 required mechanical ventilation. Age, GCS, male gender, and ISS but not NRF and/or PC were predictive of mortality. CONCLUSIONS: Increased mortality in patients with rib fractures starts at 65 years of age without a further increase until age ≥ 80. NRF does not predict increased mortality independent of age. Severe TBI is the most common cause of death in patients 16-75 years, as opposed to respiratory complications in patients 80 years-old or greater.

Linfoma MALT de localización colónica: a propósito de un caso y revisión de la literatura / Colonic MALT Lymphoma. Case report and literature review

Resumen El linfoma MALT es una forma poco frecuente de linfoma no Hodking de células B de bajo grado, que se desarrolla a expensas del tejido linfoide de las membranas mucosas. La localización más frecuente a nivel gastrointestinal es el estómago relacionando con la infección por Helicobacter pylori. El linfoma MALT colónico es una entidad extremadamente rara y cuya incidencia no supera el 5% de los casos en países asiáticos, con series porcentualmente menores al 2,5%, siendo la ubicación de este tipo de linfoma la más inusual de todo el tracto digestivo en comparación con otras neoplasias malignas que afectan al colon. Los autores exponen el caso infrecuente de presentación de linfoma tipo MALT de localización colónica en un paciente varón de 51 años, describiendo la clínica, los resultados de pruebas complementarias y el tratamiento recibido por el paciente.

Abstract MALT lymphoma is a rare form of low-grade non-Hodking B-cell lymphoma, which develops at the expense of lymphoid tissue of the mucous membranes. The most frequent location at the gastrointestinal level is the stomach related to the infection by Helicobacter pylori. Colonic MALT lymphoma is an extremely rare entity and the incidence of which does not exceed 5% of cases in Asian countries, with a series of less than 2.5%, with the location of this type of lymphoma being the most unusual of the entire digestive tract compared to other malignant neoplasms that affect the colon. The authors present the infrequent case of presentation of MALT-type lymphoma of colonic location in a 51-year-old male patient, describing the clinic, the results of complementary tests and the treatment received by the patient.

Bowel obstruction secondary to intraluminal migration of the abdominal wall mesh.

Eventration is an important public health problem due to its high incidence of around 12-15% in all laparotomies performed. The repair of an eventration has a 5-15% risk of complications. In recent years, the repair with prosthetic material has resulted in additional complications.

Implementación de un programa de cirugía proctológica en régimen de cirugía mayor ambulatoria: experiencia inicial / Early results of an ambulatory surgery programme for benign anorectal disorders

Introducción: La realización en régimen de cirugía mayor ambulatoria (CMA) de procedimientos proctológicos complejos es aún infrecuente en nuestro medio. El objetivo del presente trabajo es presentar los resultados iniciales de un programa de cirugía proctológica en régimen de CMA que incluye procedimientos complejos tales como esfinteroplastias o colgajos de avance rectal. Material y métodos: Se realizó un estudio descriptivo retrospectivo en el que se incluyeron 186 pacientes intervenidos de patología proctológica en un programa de CMA. El programa se basó en la unión de una Unidad de Coloproctología con amplia experiencia en cirugía proctológica y una Unidad de CMA ya establecida en el centro. Se analizaron los resultados tanto de ingreso como de reintervención en el postoperatorio inmediato y precoz. Resultados: Entre enero de 2014 y diciembre de 2015 se realizaron un total de 197 intervenciones, destacando 105 (53,3%) cirugías de fístula anal, 33 (16,8%) hemorroidectomías y 11 (5,6%) esfinteroplastias. De los pacientes intervenidos por fístula perianal, en 25 (23,8%) se realizó un colgajo de avance rectal. Una paciente (0,5%) requirió ingreso tras la cirugía por haberse realizado un proceso más complejo del inicialmente programado, todos los demás pacientes pudieron ser dados de alta sin complicaciones. Tres pacientes (1,5%) reingresaron en el postoperatorio precoz y fueron reoperados debido a una hemorragia poshemorroidectomía, un absceso perianal y dolor anal. Conclusiones: La implementación de un programa de patología proctológica en régimen de CMA que incluya procedimientos complejos como el colgajo de avance endorrectal o la esfinteroplastia es factible, con una baja tasa de ingresos en hospitalización y reingresos posteriores.

Introduction: Complex procedures for anorectal disorders are uncommonly performed as Ambulatory Surgery (AS). The aim of this study was to describe the early results of an AS program that included complex procedures such as advancement rectal flaps for fistula repair. Material and methods: A retrospective descriptive study was performed with 186 patients who were submitted to AS because of benign anorectal disorders. The AS program for anorectal disorders started when a Colorectal Surgery Unit with broad experience in anorectal surgery joined an AS Unit that was already working in the hospital. Hospital admissions and need of early reoperation were analyzed. Results: One hundred and ninety seven procedures were performed between January 2014 and December 2015. One hundred and five (53.3%) fistula repair surgeries were performed, as well as 33 (16.8%) hemorrhoidectomies and 11 (5.6%) anal sphincter repairs. Among the patients who were operated because of an anorectal fistulae, 25 (23.8%) were submitted to advancement rectal flap. One patient (0.5%) could not be discharged after the surgery because the procedure performed was more complex than previously expected. All other patients were discharged. Three patients (1.5%) were addmited during early postoperative course, all of them had to undergo revisional surgery because of hemorrhage, pain and anorectal abscess respectively. Conclusions: Anorectal procedures, including complex procedures such as advancement rectal flap and sphincter repair, can be performed as AS with a low percentage of patients addmited before or after discharge.

Duodenal injuries due to trauma: Review of the literature.

Duodenal injuries constitute a challenge to the Trauma Surgeon, mainly due to their retroperitoneal location. When identified, they present associated with other abdominal injuries. Consequently, they have an increased morbidity and mortality. At best estimates, duodenal lesions occur in 4.3% of all patients with abdominal injuries, ranging from 3.7% to 5%, and because of their anatomical proximity to other organs, they are rarely an isolated injury. The aim of this paper is to present a concise description of the anatomy, diagnosis, surgical management and treatment of complications of duodenal trauma, and an analysis of complications and mortality rates of duodenal injuries based on a 46-year review of the literature.
