A new medical device applied in a case of acute fecal impaction with overflow diarrhea: a case report.

BACKGROUND: Fecal impaction is a digestive system disease, that is most common in the elderly population and becomes more prevalent with increasing age. Manual removal can successfully remove the impaction in 80% of fecal impaction cases. In severe cases, endoscopy and surgery may be necessary. CASE PRESENTATION: A 78-year-old Han Chinese man living in a nursing home was diagnosed with fecal impaction; his initial symptom was overflow diarrhea, which is a rare occurrence with regard to fecal impaction. Nevertheless, we were able to effectively treat this situation by employing a new medical device that presents a novel method for addressing fecal impaction. CONCLUSION: Early identification of fecal impaction with atypical symptoms is crucial to provide proper emergency management. A safe and noninvasive treatment method, especially for elderly patients with fecal impaction, should be chosen.

Obstrucción intestinal por fecaloma gigante en adolescente con enfermedad de Hirschsprung

La enfermedad de Hirschsprung (EH) es infrecuente y la mayoría de los escasos casos se presentan en neonatos, raramente se diagnostica durante la adolescencia y menos son los casos documentados. Se presenta el caso de un varón de 16 años quien experimentó 15 días de estreñimiento, anorexia, vómitos postprandiales y distensión abdominal. Los exámenes imagenológicos mostraron un fecaloma masivo que obstruía el colon, y el examen anatomopatológico señaló EH. Ante el fracaso de medidas conservadoras de evacuación se realizó una hemicolectomía izquierda ampliada y una colostomía, más apendicectomía por obstrucción intestinal. El paciente fue dado de alta con antibioticoterapia. Este caso resalta la importancia de considerar EH en adolescentes con estreñimiento crónico y masas abdominales. Aunque los pacientes pueden experimentar problemas postoperatorios, la cirugía es el tratamiento más efectivo para la EH.

Hirschsprung's disease (HD) is uncommon, and most of the cases occur in neonates. It is rarely diagnosed during adolescence, and even fewer cases are documented. We present the case of a 16-year-old male who had 15 days of constipation, anorexia, postprandial vomiting and abdominal distension. Imaging examinations showed a massive fecaloma obstructing the colon, and histopathological examinations showed HD. Given the failure of conservative evacuation measures, an extended left hemicolectomy and colostomy were performed, plus appendectomy for bowel obstruction. The patient was discharged with antibiotic therapy. This case highlights the importance of considering HD in adolescents with chronic constipation and abdominal masses. Although patients may experience postoperative problems, surgery is the most effective treatment for HD.

Large Sigmoid Fecaloma: A Rare Case of a Common Condition in Patients With Parkinson's Disease.

A fecaloma is a rare complication of chronic constipation that is more commonly seen in elderly individuals with chronic neuropsychiatric disorders. We present the case of a 79-year-old patient with Parkinson's disease with refractory constipation due to a large fecaloma mass in the sigmoid colon, which is a rare sequela of poorly managed chronic constipation. The current report highlights the importance of aggressive medical therapy for chronic constipation in this group of patients to prevent life-threatening complications.

Apendicolito libre postapendicectomía

El apendicolito libre postapendicectomía es una complicación rara que puede ocurrir como consecuencia de la salida del apendicolito del apéndice debido a una perforación previa o al no identificar el apendicolito. El fecalito generalmente se vuelve sintomático con el tiempo, debido a la formación de un absceso, obstrucción intestinal, trayecto fistuloso o inflamación del muñón apendicular. Se describen dos casos de apendicolito libre postapendicectomía. Caso 1: mujer de 23 años, que fue sometida a una apendicectomía un día antes, ingresó por emergencia por presentar dolor en el hipogastrio. En la tomografía computarizada (TC) se evidenció un apendicolito libre en la fosa iliaca derecha, y en la laparoscopía diagnóstica se observaron abscesos intraabdominales y un apendicolito libre en el muñón apendicular. Caso 2: varón de 77 años de edad, que fue operado de apendicitis aguda causada por apendicolitos, presentó distensión abdominal al sexto día del posoperatorio. La TC reveló obstrucción intestinal y la presencia de apendicolito libre a nivel de las interasas intestinales; en la reintervención quirúrgica se evidenció erosión del mesenterio por causa del apendicolito. En ambos casos, los pacientes evolucionaron favorablemente después de las reoperaciones. Se desconoce actualmente la incidencia del apendicolito libre después de una apendicectomía, pues se dispone de pocos datos en la literatura a nivel mundial. Por tal motivo es importante la presentación de estos casos, para poder ampliar la casuística y contribuir al conocimiento de los apendicolitos libres postapendicectomía. Asimismo, permite evidenciar sus complicaciones si no son removidos precozmente y cómo prevenirlos. Conclusión: los apendicolitos libres postapendicectomía deben extraerse precozmente para evitar complicaciones.

Dropped appendicolith following an appendectomy is a rare complication which may occur as a consequence of appendicolith expulsion from the appendix due to a previous perforation or failure to identify the appendicolith. A fecalith generally becomes symptomatic over time, as a result of abscess formation, intestinal obstruction, fistula tract or inflammation of the appendiceal stump. Two cases of dropped appendicolith following an appendectomy are described hereinbelow. Case 1: A 23-year-old female patient, who underwent an appendectomy the previous day, was admitted to the emergency room due to hypogastric pain. A computed tomography (CT) scan revealed a dropped appendicolith in the right iliac fossa, and a diagnostic laparoscopy showed intra-abdominal abscesses and a dropped appendicolith in the appendicular stump. Case 2: A 77-year-old male patient, who underwent surgery for acute appendicitis caused by appendicoliths, showed abdominal distension on the sixth postoperative day. The CT scan revealed intestinal obstruction and a dropped appendicolith at bowel loops. In the surgical reintervention, erosion of the mesentery caused by the appendicolith was evidenced. Both patients progressed after the reoperations. The incidence of dropped appendicolith following an appendectomy is currently unknown since few data are available in the literature worldwide. Therefore, it is important to present these cases to expand the casuistry, learn more about dropped appendicoliths following an appendectomy, demonstrate their complications if they are not removed early and show how to prevent them. In conclusion, dropped appendicoliths following an appendectomy must be removed early to avoid complications.

A case of colonic fecal impaction caused by excessive dietary fiber intake that was endoscopically treated with intra-fecal injection of a bowel-cleansing agent.

Background and Aim: A 75-year-old man who had eaten half a head of chopped raw cabbage (approximately 600 g) daily was suffering from the left lower pain, abdominal fullness, and constipation. He was diagnosed with colonic ileus and obstructive colitis due to a fecal impaction in the sigmoid-descending junction. During colonoscopy, a tapered catheter was repeatedly inserted into the impacted feces to inject a bowel-cleansing agent. Finally, the feces were broken to be fragmented enough to path the endoscope through. After the procedure, his symptoms were immediately relieved. Relevance for Patients: Excessive dietary fiber intake can induce fecal ileus. Endoscopic treatment with intra-fecal injection of a bowel-cleansing agent is useful and worth attempting for disimpaction of feces.

Efficacy and safety of anal encirclement combining the Leeds-Keio artificial ligament with injection sclerotherapy using aluminum potassium sulfate and tannic acid in the management of rectal prolapse: a single-center observational study.

PURPOSE: Perineal procedures are an important surgical option for frail and high-risk patients with rectal prolapse. This study aimed to evaluate the efficacy and safety of combined therapy using injection sclerotherapy, with aluminum potassium sulfate and tannic acid (ALTA), and the Thiersch procedure, using the Leeds-Keio ligament (ALTA-Thiersch). METHODS: This study included 106 consecutive patients (mean age, 81.2 years) who underwent ALTA-Thiersch for rectal prolapse. The procedure was performed under caudal epidural anesthesia. ALTA was injected into the submucosa from the tip of the prolapsed rectum down to the dentate line, circumferentially, at 20 to 40 locations. The ligament tape was placed outside the external sphincter muscle and at an approximate depth of 2 cm into the middle anal canal. RESULTS: Of 106 patients, rectal prolapse was cured shortly after surgery in 105 patients. An additional tape was inserted in 1 patient who had persistent prolapse. Postoperative complications were observed in 27 patients (25.5%). Fecal impaction occurred in 12 patients; however, since it was temporary, no tape removal was required. Of the 12 cases in which the tape was infected or exposed, 11 required tape removal. There were 18 cases of recurrence at a mean follow-up of 22.1 months. Cumulative recurrence rates at 3 and 5 years were 21.3% and 38.6%, respectively. CONCLUSION: ALTA-Thiersch is a simple and safe procedure for rectal prolapse, having reasonable outcomes. The use of the Leeds-Keio ligament for anal encircling can help compensate for the disadvantages of the Thiersch operation.

A fecalith mimicking a bladder calculus secondary to an appendicovesical fistula: a case report.

An appendicovesical fistula is defined as an abnormal communication between the appendix and the urinary bladder, with only a few cases reported in the literature. It is very challenging to make an early diagnosis, due to the inability of conventional imaging modalities to detect this unique pathology. The symptoms are often mild, and there are not any specific signs or symptoms that might suggest this type of anomalous communication. We report a case of a 27-year-old male patient who presented difficulty for initiating urination, dysuria, and persistent urinary tract infections. An abdominal x-ray showed a large calculus inside the bladder. A cystoscopy was performed, where the tip of the appendix was seen protruding inside the bladder with a large fecalith adhered to the bladder wall. An appendectomy and partial cystectomy with primary repair were auspiciously achieved. A review of the literature is also presented.

Emphysematous gastritis associated with ileus due to fecal impaction.

Background: Gastric emphysema and emphysematous gastritis (EG) are rare diseases involving air being introduced into the stomach wall. Emphysematous gastritis is an infectious disease with a high fatality rate. Case presentation: An 83-year-old woman had recovered from septic shock, however, an antibiotic-refractory inflammatory response remained. She was diagnosed with pseudogout and administered a non-steroidal anti-inflammatory drug. However, abdominal pain, prominent abdominal distension, and strawberry milk-like gastric juice were recognized. Computed tomography showed ileus due to fecal impaction and GE. The results of culture of the gastric juice were positive (Pseudomonas aeruginosa and Enterococcus faecalis). Disimpaction, fasting management, and antibacterial treatments resulted in the recovery of her symptoms. Conclusion: This is the first case in which ileus associated with fecal impaction caused EG. The present case highlights the importance of promoting regular bowel movements.

Pneumatosis intestinalis: Not always bowel ischemia.

Pneumatosis intestinalis or abnormal intramural gas within the digestive tract usually suggests bowel ischemia necessitating urgent surgery. We report the case of an 82-year-old female presenting with hypotension and nausea, with a past history of schizophrenia, low grade chronic lymphocytic leukemia, stroke, bronchitis and rheumatoid arthritis. Computed tomography performed demonstrated extensive submucosal gas within the entire small bowel, associated with free gas in the peritoneal cavity. Bowel ischemia was diagnosed radiologically. However, a benign diagnosis of fecal impaction was ultimately made due to the patient's stable clinical status. Clinical correlation and close monitoring of clinical status in this context is of greatest diagnostic assistance when encountered with this phenomenon, to prevent unnecessary harm to the patient.

A Case Report of Impacted Fecalith Within Mucosal Pouch: An Unusual Cause of Colocolic Intussusception.

Intussusception involving the colon is unusual in adults and when present is managed with resection due to the risk of malignancy. We present an unusual case where the intussusceptum was impacted stool in a mucosal pouch in the transverse colon. The patient presented with bleeding per rectum and abdominal pain and was found to have a colocolic intussusception on computed tomography. Colonoscopy showed an ulcerated mass in the transverse colon. A laparoscopic right hemicolectomy was performed. Histopathology demonstrated known chronic lymphocytic leukemia, but not solid malignancy. A large fecalith impacted within a mucosal pouch had acted as the lead point. This represents a highly unusual but benign cause of intussusception.

Stercoral colitis due to massive fecal impaction: a case report and literature review.

Stercoral colitis is a rare inflammatory condition involving the large bowel wall secondary to fecal impaction. Stercoral colitis has a clinical course ranging from non-complicated fecaloid impaction to colonic perforation. This case report aims to give a brief review of this condition and discuss its imaging findings. CASE PRESENTATION: We herein report a case 74-year-old female who presented with abdominal pain, abdominal distension, and the absence of gas-feces discharge for a few days. The patient had a one-year history of chronic constipation and recent femoral neck fracture surgery. Physical examination shows abdominal distension with slight tenderness. Abdominal radiographs demonstrated bowel distention and fecal material in the colorectal regions. Computed tomography (CT) images demonstrated abundant fecal material with massive dilatation in the rectosigmoid colon, focal mural thickening, subtle pericolic fat stranding, and minimal free fluid in the abdominal and pelvic cavities. Based on these findings, the diagnosis of stercoral colitis was made. The patient was treated conservatively and eventually discharged with a good health condition. CONCLUSION: Stercoral colitis seems to be more common in elderly patients with comorbid diseases. Chronic constipation causing fecal impaction is a major risk factor. CT scan is the most helpful imaging modality for the diagnosis of stercoral colitis. CT findings that should prompt the radiologist to consider this diagnosis include colonic dilatation containing impacted feces, mural thickening, and pericolic fat stranding. If the fecal impaction is not promptly relieved, life-threatening complications such as colonic perforation can occur.

The usefulness of olive oil enema in children with severe chronic constipation.

PURPOSE: Few reports have determined the efficacy of olive oil enemas for severe constipation. Here, we review our experience with olive oil enemas in children with severe chronic constipation. METHODS: In our outpatient pediatric surgery department, the charts of 118 patients prescribed with olive oil enemas between January 2010 and November 2019 were retrospectively reviewed. A 1-2 ml/kg olive oil enema was given either alone or followed several hours later by a glycerin enema. Ratings included "very effective (VE)," "effective (E)," "limited (L)," "ineffective (I)," and "unknown (U)." RESULTS: One hundred and fifteen (97.5%) patients were able to use olive oil enemas at home. Forty-nine had functional constipation; 43 had anorectal malformation; 40 had Hirschsprung disease; 12 had spina bifida; and 10 had other maladies. Used as an enema, olive oil was effective in treating fecal impaction in 77.6% of patients; as a lubricant, it was effective in treating 76.9% of patients. Efficacy for fecal disimpaction was similar among patients with different underlying disorders. CONCLUSION: Olive oil enemas are useful for more than three-quarters of children with severe chronic constipation. Further study is warranted to add olive oil enemas as an adjunctive treatment in the management of severe constipation.

Successful Resolution of Fecal Impaction During Endoscopy Using a Looped Guidewire.

Fecal impaction is the impaired excretion of a large fecal mass, and mild cases are treated by enema and osmotic laxatives. However, treatment-resistant cases need more invasive alternatives. A woman in her 60s presented with abdominal discomfort. Her abdomen was soft and without tenderness. Computed tomography revealed a large mass of feces in her sigmoid colon and no intestinal dilatation proximal to the mass. Endoscopy confirmed a fecal mass occupying the lumen. A glycerin enema, oral administration of polyethylene glycol, and enteral administration of amidotrizoic acid during colonoscopy were ineffective. We maneuvered a guidewire to form a loop at the tip of an endoscope, with which we subdivided the mass for successful removal. The patient's abdominal discomfort disappeared immediately. Endoscopic disimpaction is far less invasive than surgery and should be considered when treating fecal impaction cases, without severe obstructive colitis, which are nonresponsive to conservative treatment.

Fecal impaction is associated with postoperative urinary retention after hip fracture surgery.

BACKGROUND: Postoperative urinary retention (POUR) is a common hip fracture (HF) complication. Although fecal impaction (FI) is one of the oft-cited causes of POUR in clinical practice, evidence regarding this association is scarce. OBJECTIVE: The aim of this study was to determine whether FI was associated with POUR after HF surgery in older patients. METHODS: All patients consecutively admitted after a HF surgery in a geriatric perioperative unit were included in this cross-sectional study. FI was systematically assessed by a digital rectal exam at admission and according to clinical suspicion during the hospital stay. The dependent variable was POUR, systematically screened according to the department protocol and defined as a bladder volume>400ml requiring catheterization. The association between FI and POUR was assessed by multivariable analysis. RESULTS: A total of 256 patients were included (mean [SD] age 86 [6] years), (76% women): 108 (42%) presented FI and 63 (25%) POUR. The frequency of FI was higher with than without POUR (73% vs. 32%, P<0.001). On multivariable analysis, after adjusting for age, sex, Cumulative Illness Rating Scale score and anticholinergic load, FI was the only factor independently associated with POUR (odds ratio 4.78) [95% confidence interval 2.44-9.71], P<0.001. CONCLUSIONS: FI was the only independent factor associated with POUR after HF surgery in older adults. Further studies are needed to optimize perioperative geriatric care including FI and POUR assessment and management.

Abdominal compartment syndrome due to extremely elongated sigmoid colon and rectum plus fecal impaction caused by disuse syndrome and diabetic neuropathy: a case report and review of the literature.

BACKGROUND: Abdominal compartment syndrome (ACS) is defined as a sustained raised level of intra-abdominal pressure more than 20 mmHg with or without abdominal perfusion pressure less than 60 mmHg and the development of new end-organ failure. Abdominal surgery, major trauma, volvulus, ileus, distended abdomen, fecal impaction, acute pancreatitis, liver dysfunction, sepsis, shock, obesity, and age have all been reported as risk factors. Herein, we report the severest known case of ACS due to extremely elongated sigmoid colon and rectum plus fecal impaction caused by disuse syndrome and diabetic neuropathy, together with a brief review of the literature. CASE PRESENTATION: A 48-year-old Asian man suffering from shock was transported by ambulance to our hospital. His medical history included hypoglycemic encephalopathy sequelae, disuse syndrome, type 2 diabetic neuropathy, and constipation. He recovered consciousness in the ambulance, and his physical examination as well as laboratory findings were normal. X-ray and dynamic computed tomography revealed a thickened gut wall, and an extremely dilated sigmoid colon and rectum filled with a massive amount of stool as well as gas, compressing other intra-abdominal organs. We diagnosed the patient with transient vasovagal syncope, together with ACS, due to extremely elongated sigmoid colon and rectum plus fecal impaction, caused by anorectal disturbance derived from disuse syndrome and diabetic neuropathy. We first repeated stool extraction for bowel decompression and he subsequently became symptom-free, after which we performed a colostomy on the 28th hospital day. The postoperative course was uncomplicated, and he was discharged on the 44th hospital day. CONCLUSIONS: Clinicians need to keep ACS in mind as a differential diagnosis and perform careful and detailed examination when encountering patients presenting with symptoms or risk factors of ACS. In addition, they need to precisely diagnose ACS and perform optimal treatment without delay.

Acute urinary retention in children.

BACKGROUND: Acute urinary retention is a common emergency in adult patients, foremost in older men. In childhood urinary retention is a rare entity with only sparse literature on the etiology. OBJECTIVE: To assess the etiology and treatment of acute urinary retention in the pediatric population and assess age and sex distribution. STUDY DESIGN: A retrospective analysis of all patients admitted to our emergency department with acute urinary retention between 2005 and 2019 was performed. Exclusion criteria were newborns (because of physiologic postnatal oliguria) and postoperative urinary retention during the same hospital stay. RESULTS: 113 children with acute urinary retention (ICD: R33) meeting the above criteria were identified. 16 Patients were excluded because of incomplete medical charts. 97 children were included into the study (age 0.5-18.3 years, mean age 5.3 years). 89 patients had one episode, 8 patients two episodes. A peak around the third year of age was observed. Sex ratio showed a 2:1 male to female distribution. Most common etiology was balanoposthitis (15.5%) and acute constipation/fecal impaction (15.5%). Traumatic urinary retention was found in 11.4% of the cases. Urinary tract infection were found 7.2%. No underlying reason could be found in 12.4% (idiopathic urinary retention). Other causes included febrile non-urinary infection (8.2%), subvesical obstruction (4.1%), vulvovaginitis (3.1%) and urethritis (2.1%). In 50% of the cases of urinary retention under 1 year of age (2 out of 4) an underlying tumor (rhabdomyosarcoma, sacral teratoma) was identified. DISCUSSION: Age and sex distribution were similar to previously published series; however, this study shows a marked difference concerning the etiology: e. g. we identified a significantly higher proportion of functional disorders as a reason for acute urinary retention in childhood. It is hypothesized that this is partly because previously published studies originate from areas (USA, Israel, Iran) with different socio-demographic and cultural background. CONCLUSION: AUR in children is a rare condition with very heterogeneous causes. Although the majority of cases exhibit mild underlying conditions, serious reasons, such as malignant diseases especially in the first year of life, must be excluded. AUR relief without catheterization is a child-friendly approach in cases of mild inflammatory or functional disorders and can help to minimize traumatization.

Distal Intestinal Obstruction Syndrome resolved by dissolution with Coca-Cola® via colonoscopy in a cystic fibrosis patient.

We report the case of a 37 years old woman who presented to emergency department because of a 3 days history of abdominal disconfort and distension. After physical examination and a CT scan of the abdomen she was diagnosed of Distal Intestinal Obstruction Syndrome (DIOS) in the context of her underlying cystic fibrosis. Conservative management was attempted with no improvement. A colonoscopy was performed and thick solid feces were seen filling the cecum and right colon. An attempt to dissolve the impacted stool was made by instilling one liter of Diet Coca-Cola® through the working channel of the colonoscope. After that, the condition of the resolved in the following 24 h with no more interventions.

A case of stercoral colitis with marked elevation of serum carcinoembryonic antigen.

It should be noted that the serum CEA level can become elevated in severe stercoral colitis. Marked elevation of the serum CEA level in stercoral colitis may suggest the necessity of surgery in patients with stercoral colitis.

Complicación mortal de colitis estercorácea en paciente octogenaria / Fatal complication of stercoral colitis in octogenarian patient

La colitis estercorácea se describe como un proceso inflamatorio que afecta a la pared colónica en relación con el aumento de la presión intraluminal por impactación fecal . Se presenta generalmente en ancianos con múltiples comorbilidades, lo que puede facilitar la aparición de complicaciones potencialmente mortales. Debido a sus síntomas inespecíficos, requiere del uso de imágenes diagnósticas para instaurar un tratamiento precoz . Se presenta un caso clínico, diagnosticado en nuestro centro, de colitis estercorácea complicada con múltiples abscesos hepáticos piógenos.

Stercoral colitis is an inflammatory process of the colonic wall caused by increased luminal pressure resulting from fecal impaction. It is generally seen in elderly patients with multiple comorbidities which facilitate potentially fatal complications. Diagnostic imaging is required for initiation of prompt treatment as its symptoms are non-specific. We present a clinical case of stercoral colitis complicated by multiple pyogenic hepatic abscesses diagnosed in our centre.

Differentiation between stercoral perforation and colorectal cancer perforation

SUMMARY OBJECTIVE: To determine the computed tomography (CT) signs associated with stercoral perforation and colorectal cancer perforation. MATERIALS AND METHODS: From May 2003 to Feb. 2015, all surgically and pathologically confirmed patients with stercoral perforation (n=8, mean age 68.3 years) or colon cancer perforation (n=11, mean age 66.3 years) were retrospectively reviewed by two board-certified radiologists blinded to the proven diagnosis. The following CT findings were evaluated and recorded for each patient: wall thickness of the distal colon adjacent to perforation site, pattern of the colon wall thickening and enhancement, length of the thickened bowel wall, presence of fecaloma, degree of proximal colon dilatation, and pericolonic inflammation or presence of pericolonic abscess, and number of enlarged pericolonic lymph nodes. These findings were correlated with the pathologic diagnosis. RESULTS: The mean thickness of the distal colonic wall adjacent to the perforation site was 13.6 mm in patients with colorectal cancer perforation and 5.1 mm with stercoral perforation, which was statistically different. There was a significant correlation between colorectal cancer perforation and eccentric wall thickening (p<0.01). CT findings of layered enhancing wall thickening (p<0.01) and the presence of fecaloma in the proximal colon (p<0.01) were significant findings for stercoral perforation. Patients with colorectal cancer displayed more pericolonic lymph nodes (mean 2.27, p<0.05). CONCLUSION: Fecaloma in the proximal colon and layered enhancing wall thickening adjacent to perforation site are likely due to stercoral perforation. Eccentric bowel wall thickening at the distal portion of the perforation site with many enlarged pericolonic lymph nodes is most likely due to colorectal cancer perforation.

RESUMO OBJETIVO: Determinar os sinais de CT associados à perfuração estercoral e perfuração do câncer colorretal. MÉTODOS: De maio de 2003 a fevereiro de 2015, todos os pacientes cirurgicamente e patologicamente confirmados com perfuração estercoral (n = 8, idade média de 68,3 anos) ou perfuração de câncer de cólon (n = 11, idade média de 66,3 anos) foram revisados retrospectivamente por dois radiologistas certificados por placa cegados ao diagnóstico comprovado. Os seguintes achados CT foram avaliados e gravados para cada paciente: espessura da parede do cólon distal adjacente ao local da perfuração, padrão de espessamento e realce da parede do cólon, comprimento da parede intestinal espessada, presença de fecaloma, grau de dilatação do cólon proximal e inflamação pericolônica ou presença de abscesso pericolônico e número de linfonodos pericolônicos aumentados. Esses achados foram correlacionados com o diagnóstico patológico. RESULTADOS: A espessura média da parede colônica distal adjacente ao local de perfuração foi de 13,6 mm em pacientes com perfuração de câncer colorretal e 5,1 mm com perfuração estercoral, que foi estatisticamente diferente. Houve uma correlação significativa entre a perfuração do câncer colorretal e o espessamento da parede excêntrica (p < 0,01). Os achados de CT de espessamento de parede aprimorada em camadas (p < 0,01) e presença de fecaloma no cólon proximal (p < 0,01) foram achados significativos para perfuração estercoral. Os pacientes com câncer colorretal apresentaram mais linfonodos pericolônicos (média 2,27, p < 0,05). CONCLUSÃO: O fecaloma no cólon proximal e o espessamento da parede que aumenta a camada adjacente ao local da perfuração são provavelmente devidos à perfuração estereocálica. O espessamento da parede intestinal excêntrica na porção distal do local da perfuração com muitos gânglios linfáticos pericolônicos aumentados é provavelmente a perfuração do câncer colorretal.
