Successful emergency surgery for accidental ingestion of multiple neodymium magnets in an Argentine tegu (Salvator merianae).

A large Argentine tegu (Salvator merianae) presented with anorexia. Initial radiographs revealed a metallic foreign body in the stomach. The tegu vomited and became inactive two days later. A follow-up radiograph revealed the persistence of the foreign body in the same region. The foreign body was identified as a cluster of multiple magnets resembling neodymium magnets reported missing by the owner. An emergent laparotomy was performed due to gastrointestinal perforations caused by the multiple magnets. The surgical intervention revealed perforations in the walls of the stomach and small intestine and progressing acute peritonitis. Three magnets were extracted from the abdominal cavity and the tegu showed recovery. At 200 days postoperatively, the tegu continued to demonstrate good appetite and energy levels.

Necrotizing fasciitis of the thigh secondary to perforated rectal cancer: the sciatic foramen as a route for infective spread.

Necrotizing fasciitis (NF) is a potentially life-threatening surgical emergency. It is a rapidly progressive infection of soft tissues, and mortality is related to the degree of sepsis and the general condition of the patient. It is a rare condition that requires a rapid diagnosis and surgical treatment is aggressive debridement. There are a small number of reported cases of perforation of a rectal malignancy leading to NF of the thigh. We present a case with rectal cancer in which the sciatic foramen had provided a channel for the spread of pelvic infection into the thigh.

La fascitis necrotizante es una emergencia quirúrgica potencialmente mortal. Es una infección de tejidos blandos rápidamente progresiva y la mortalidad está relacionada con el grado de sepsis y el estado general del paciente. Es una condición poco común que requiere un diagnóstico rápido, y el tratamiento quirúrgico consiste en un desbridamiento agresivo. Existe un pequeño número de casos notificados de perforación de neoplasia maligna de recto que conduce a fascitis necrotizante del muslo. Presentamos un caso de cáncer de recto en el cual el foramen ciático fue el canal para la propagación de la infección pélvica al muslo.

[Necrosis and intestinal perforation associated with feeding by jejunostomy]. / Necrosis y perforación intestinal asociada a alimentación por yeyunostomía.

Enteral nutrition through jejunostomy is a common practice in any general surgery service; it carries a low risk of complications and morbidity and mortality. We present the case of a patient with an immediate history of subtotal gastrectomy that began nutrition through jejunostomy and complicated with intestinal necrosis due to non-occlusive ischemia in the short period. The purpose of this work is to report on this complication, its pathophysiology and risk factors to take it into account and be able to take appropriate therapeutic action early.

Presentamos el caso de una paciente con antecedente inmediato de gastrectomía subtotal que inició nutrición por yeyunostomía y complicó con necrosis intestinal por isquemia no oclusiva en el corto lapso. La finalidad de este trabajo es informar sobre esta complicación, su fisiopatología y factores de riesgo para tenerla en cuenta y poder tomar precozmente una conducta terapéutica adecuada.

Management of post-ERCP duodenal perforations: experience at Hospital Juárez de México.

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) is an endoscopic study in which the duodenum is observed laterally, and the bile duct is instrumented. There are several indications and complications in the procedure. OBJECTIVE: To determine the incidence of duodenal perforations, using the Stapfer classification in the Hospital Juárez de Mexico over a period of 5 years, as well as the management implemented in such cases. METHOD: The study was carried out at the Hospital Juárez de Mexico of the Ministry of Health. All patients who underwent ERCP between January 1, 2017, to May 30, 2022 were included. RESULTS: 485 ERCP were performed in the study period. Incidence of 1.6% post-ERCP duodenal perforation. The average age of the subjects 56.37 years. In-hospital stay of post-ERCP perforations averaged 9.37 days. The time of the endoscopic study at the time of the surgical procedure is 10 h on average. CONCLUSIONS: Post-ERCP duodenal perforation is a complication that occurs with a low incidence, it tends to increase the number of days of in-hospital stay and increases morbimortality of patients; therefore, it is important to be always alert.

Sigmoid resection and primary anastomosis for perforated diverticulitis with peritonitis: To divert or not to divert-A systematic review and meta-analysis.

BACKGROUND: The role of proximal diversion in patients undergoing sigmoid resection and primary anastomosis for diverticulitis with generalized peritonitis is unclear. The aim of this study was to compare the clinical outcomes of sigmoid resection and primary anastomosis and sigmoid resection and primary anastomosis with a proximal diversion in perforated diverticulitis with diffuse peritonitis. METHOD: A systematic literature search on sigmoid resection and primary anastomosis and sigmoid resection and primary anastomosis with proximal diversion for diverticulitis with diffuse peritonitis was conducted in the Medline and EMBASE databases. Randomized clinical trials and observational studies reporting the primary outcome of interest (30-day mortality) were included. Secondary outcomes were major morbidity, anastomotic leak, reoperation, stoma nonreversal rates, and length of hospital stay. A meta-analysis of proportions and linear regression models were used to assess the effect of each procedure on the different outcomes. RESULTS: A total of 17 studies involving 544 patients (sigmoid resection and primary anastomosis: 287 versus sigmoid resection and primary anastomosis with proximal diversion: 257) were included. Thirty-day mortality (odds ratio 1.12, 95% confidence interval 0.53-2.40, P = .76), major morbidity (odds ratio 1.40, 95% confidence interval 0.80-2.44, P = .24), anastomotic leak (odds ratio 0.34, 95% confidence interval 0.099-1.20, P = .10), reoperation (odds ratio 0.49, 95% confidence interval 0.17-1.46, P = .20), and length of stay (sigmoid resection and primary anastomosis: 12.1 vs resection and primary anastomosis with diverting ileostomy: 15 days, P = .44) were similar between groups. The risk of definitive stoma was significantly lower after sigmoid resection and primary anastomosis (odds ratio 0.05, 95% confidence interval 0.006-0.35, P = .003). CONCLUSION: Sigmoid resection and primary anastomosis with or without proximal diversion have similar postoperative outcomes in selected patients with diverticulitis and diffuse peritonitis. However, further randomized controlled trials are needed to confirm these results.

Intestinal perforation as a form of presentation of a small bowel calcifying fibrous tumor.

Calcifying fibrous tumor (CFT) is a rare, benign, mesenchymal tumor. It has a slight female predominance, and it can appear in any range of age. It can be in the extremities, neck, and gastrointestinal tract, but it has also been described in other locations. Even though it is a benign lesion, recurrence has been described in some cases in the literature. A free-margin surgical resection is the recommended treatment. We present a 56 -year-old woman who underwent surgery for an intestinal obstruction associated with middle jejunum perforation. Histopathological study described the presence of a calcifying fibrous tumor. Spindle cells were positive for CD34, Factor XIIIa and vimentin. To our knowledge, this is the first case of intestinal perforation secondary to a calcifying fibrous tumor described in the literature.

[Perforation of Meckel's diverticulum by a fishbone]. / Perforatsiya divertikula Mekkelya ryb'ei kost'yu.

Meckel's diverticulum is the most common congenital defect of the gastrointestinal tract. It is most often silent or asymptomatic. However, acute abdominal signs of obstruction, inflammation, hemorrhage and perforation are possible in other cases. Different foreign bodies can cause perforation of Meckel's diverticulum. We present an 18-year-old male who presented to the emergency department with abdominal pain within 48 previous hours. After evaluation, acute appendicitis was diagnosed and he underwent laparoscopic appendectomy. Meckel's diverticulum perforated by a fish bone was intraoperatively discovered. Incidental appendectomy and segmental resection of the ileum were performed.

Hartmann's procedure versus primary anastomosis for Hinchey stage III diverticulitis: a prospective case-control study.

INTRODUCTION: Hartmann's procedure (HP) is the conventional treatment in patients with complicated diverticulitis. Segmental resection with primary anastomosis (PA) is a treatment alternative for those patients. Our aim was to compare the postoperative results of HP and PA in patients with complicated diverticulitis (Hinchey stage III). METHODS: A case-control study was conducted on patients operated on for purulent Hinchey stage III diverticulitis, within the time frame of 2000 and 2019. RESULTS: Twenty-seven patients that underwent PA were compared with 27 that underwent HP. The patients that underwent HP had a greater probability of morbidity at 30 days (OR 3.5; 95% CI 1.13-11.25), as well as a greater probability of major complications (OR 10.9; 95% CI 1.26-95.05). CONCLUSION: The patients that underwent segmental resection and PA presented with lower morbidity rates and higher stoma reversal rates than the patients that underwent HP.

Resultados de la cirugía de urgencia en pacientes con cáncer de colon perforado / Results of emergency surgery in patients with perforated colon cancer

RESUMEN: Gran parte de los pacientes con cáncer de colon (CC), son diagnosticados y tratados de forma electiva. Sin embargo, aproximadamente un 20 % de ellos debutará como una emergencia (obstrucción o perforación). El objetivo de este estudio fue determinar morbilidad postoperatoria (MPO) y supervivencia global (SVG) en pacientes resecados por CC perforado (CCP). Serie de casos retrospectiva de pacientes con CCP, sometidos a colectomía y linfadenectomía, de forma consecutiva, en Clínica RedSalud Mayor y Hospital de Temuco, Chile, entre 2010 y 2019. Las variables resultados fueron SVG y MPO. Otras variables de interés fueron: tiempo quirúrgico, resecabilidad, número de linfonodos resecados, estancia hospitalaria, mortalidad operatoria, recurrencia y supervivencia libre de enfermedad (SLE). Los pacientes fueron seguidos de forma clínica. Se utilizó estadística descriptiva, con medidas de tendencia central y dispersión; y análisis de SV con curvas de Kaplan Meier. Se intervinieron 15 pacientes (60 % mujeres), con una mediana de edad de 62 años. La localización más frecuente fue sigmoides (6 casos; 40,0 %). La resecabilidad de la serie fue 100 %. La medianas del tiempo quirúrgico, número de linfonodos resecados y estancia hospitalaria; fueron 80 min, 20 y 5 días respectivamente. La MPO fue 26,7 % (4 casos). Con una mediana de seguimiento de 36 meses, se verificó una recurrencia de 40,0 %. Por otra parte, la SVG y SLE a 5 años fue 46,7 % y 33,3 % respectivamente. Los resultados obtenidos, en términos de MPO y SVG, fueron similares a series internacionales.

SUMMARY: Most patients with colon cancer (CC) are diagnosed and treated electively. However, a fifth of them will debut as an emergency (obstruction or perforation). The aim of this study was to determine postoperative morbidity (POM) and overall survival (OS) in patients resected by perforated CC (PCC). Retrospective case series of patients with PCC undergoing colectomy and lymphadenectomy, consecutively, at RedSalud Mayor Clinic and Temuco hospital, Chile, between 2010 and 2019. The outcome variable were POM and OS. Other variables of interest were surgical time, resectability, number of resected lymph nodes, hospital stay, mortality, recurrence, and disease-free survival (DFS). Patients were followed clinically. Descriptive statistics was used (measures of central tendency and dispersion), and OS analysis was applying Kaplan Meier curves.15 patients (60 % women) were intervened, with a median age of 62 years. The most frequent location was the sigmoid colon (6 cases, 40.0 %). Resectability of the series was 100 %. Median surgical time, number of lymph nodes resected, and hospital stay; they were 80 min, 20 and 5 days respectively. POM was 26.7 % (4 cases). With a median follow-up of 36 months, recurrence was 40.0 %. On the other hand, OS and DFS at 5 years were 46.7 % and 33.3 %, respectively. The observed results, in terms of POM and OS, were like international series.

Jejunal perforation secondary to kick during kick-boxing practice: laparoscopic management.

Small bowel injury in a sports setting is a rare occurrence with a paucity of reported cases. A 30-year old male patient consulted for generalized abdominal pain subsequent to secondary blunt abdominal trauma during kick-boxing practice. A computed tomography scan of the abdomen and pelvis revealed a moderate amount of free fluid in both the parietocolic space and the rectovesical pouch, with perihepatic pneumoperitoneum. Emergency laparoscopy was indicated and a closure of small bowel defect was performed. Diagnosis of small bowel injuries is difficult, resulting in delayed treatment and increased mortality and morbidity.

La lesión intestinal en un entorno deportivo es infrecuente con pocos casos comunicados. Un varón de 30 años consultó por dolor abdominal generalizado posterior a un traumatismo abdominal cerrado secundario a la práctica de kick-boxing. Una tomografía computarizada de abdomen y pelvis reveló líquido libre tanto en el espacio parietocólico como en la bolsa rectovesical, con neumoperitoneo perihepático. Se indicó laparoscopia exploradora con cirugía de rafia intestinal. El diagnóstico de las lesiones del intestino delgado es difícil, lo que provoca un retraso en el tratamiento y un aumento de la mortalidad y la morbilidad.

Multiple Jejunal diverticulosis complicated by perforation: case report and a brief literature review

Background: Multiple small-bowel diverticulosis comprises a rare entity with probable underestimated incidence, and that may be the reason why it is sometimes overlooked when managing cases with peritonitis. Case report: In the present paper, we report the case of a 76-year-old male presenting abdominal pain and fever in an acute setting. Computed tomography (CT) scans revealed jejunal thickening and numerous images of saccular addition that were interpreted as jejunoileal diverticulitis. After an initial period of clinical treatment, surgical management was indicated based on a worsening clinical picture and the presence of an extraluminal focus of gas detected in a subsequent CT scan. Through a laparoscopic approach, multiple small-bowel diverticula and a tamponade perforation were found. A segmental intestinal resection was performed, and the patient was discharged after a ten days. Conclusions: Multiple jejunal diverticulosis is a rare condition that should be remembered in the setting of an acute abdomen. As it prevails among older patients, early diagnosis with radiological aid is crucial to establish the most adequate management, including intestinal resection, if necessary. (AU)

Surgical management of duodenal perforation after endoscopic retrograde cholangiopancreatography: case series.

BACKGROUND: Complications after endoscopic retrograde cholangiopancreatography (ERCP) are rare, approximately 0.09% to 1.8% are duodenal perforation. This type of injury requires early diagnosis and proper management since the outcomes can be catastrophic, leading to death in 20% of cases. OBJECTIVE: To show our experience in the management of these injuries in order to establish if there is benefit from minimally invasive management versus conventional management. METHOD: Observational, retrospective and descriptive study comparing patients who required surgical management after post-ERCP duodenal perforation in three centers in Bogotá, Colombia, between January 2013 and December 2018. RESULTS: 13 patients were taken to surgical management after duodenal perforation post ERCP, 7 laparoscopically (53.8%), with an average hospital stay of 10.7 days and mortality of 0% and 6 by open route (46.1%), with an average hospital stay of 33 days and mortality of 50%, with a minimum follow-up of 6 months. CONCLUSIONS: Post ERCP duodenal perforation, despite its low incidence, should be suspected due to its high mortality. Laparoscopic surgery is a good tool to address duodenal perforations after ERCP, because it presents a lower rate of complications and mortality.

ANTECEDENTES: Las complicaciones tras la colangiopancreatografía retrógrada endoscópica (CPRE) que necesitan manejo quirúrgico son limitadas y aproximadamente el 0.09-1.8% corresponden a perforación duodenal. Este tipo de lesiones requieren un diagnóstico temprano y un manejo adecuado, ya que los desenlaces pueden ser catastróficos, con una mortalidad reportada de hasta el 20%. OBJETIVO: Presentar nuestra experiencia en el manejo quirúrgico de estas lesiones. MÉTODO: Estudio observacional, retrospectivo y descriptivo, de pacientes que requirieron manejo quirúrgico por perforación duodenal tras CPRE en tres centros de Bogotá, Colombia, entre enero de 2013 y diciembre de 2018. RESULTADOS: Fueron llevados a manejo quirúrgico 13 pacientes, 7 (53.8%) por vía laparoscópica, con una estancia hospitalaria promedio de 10.7 días y una mortalidad del 0%, y 6 (46.1%) por vía abierta, con una estancia hospitalaria promedio de 33 días y una mortalidad del 50%, con seguimiento mínimo a 6 meses. CONCLUSIONES: La perforación duodenal tras una CPRE, pese a su baja incidencia, se debe sospechar por su alta morbimortalidad. La decisión del abordaje quirúrgico está condicionada por el estado clínico del paciente, y por ende está ligada al pronóstico de este.

[Ingestion of multiple magnets in pediatrics: endoscopic or surgical emergency?] / Ingestión de múltiples imanes en pediatría: ¿emergencia endoscópica o quirúrgica?

Ingestion of foreign bodies is common in the pediatric population. Most foreign bodies have a benign behavior and are usually eliminated without generating greater morbidity and mortality. In relation to the intake of magnets, its frequency has increased to the point that it currently represents a public health problem in the pediatric population. The ingestion of a single magnet does not generate any risk, but the ingestion of 2 or more of these, or even of magnets and metals in succession is considered an emergency since they can attract each other and can cause serious symptoms of intestinal obstruction, bleeding, fistulas, perforation and even intestinal necrosis. We present 2 pediatric patients, who ingested multiple magnets, in these cases we highlight the variety in the clinical presentation, as well as the complications presented in relation to a late diagnosis.

Treatment of intestinal tuberculosis with small bowel perforation: a case report.

BACKGROUND: Diagnosis of intestinal tuberculosis poses a dilemma to physicians due to nonspecific symptoms like abdominal pain, fever, nausea, and a change in bowel habit. In particular, the distinction between inflammatory bowel disease and intestinal tuberculosis remains challenging. CASE PRESENTATION: A 27-year-old man from Colombia presented with fever, night sweats, and progressive lower abdominal pain. Computed tomography revealed a thickening of the bowel wall with a mesenterial lymphadenopathy, ascites ,and a pleural tumor mass. Histology of intestinal and pleural biopsy specimens showed a granulomatous inflammation. Although microscopy and polymerase chain reaction (PCR) for Mycobacterium tuberculosis (MTB) were negative, empirical MTB treatment was initiated on suspicion. Due to a massive post-stenotic atrophied intestinal bowel, MTB medications were administered parenterally in the initial phase of treatment to guarantee adequate systemic resorption. The complicated and critical further course included an intra-abdominal abscess and bowel perforation requiring a split stoma, before the patient could be discharged in good condition after 3 months of in-hospital care. CONCLUSIONS: This case highlights the clinical complexity and diagnostic challenges of intestinal MTB infection. A multidisciplinary team of physicians should be sensitized to a timely diagnosis of this disease, which often mimics inflammation similar to inflammatory bowel disease, other infections, or malignancies. In our case, radiological findings, histological results, and migratory background underpinned the suspected diagnosis and allowed early initiation of tuberculostatic treatment.
