Colorectal Oncologic Emergencies: Recognition, Management, and Outcomes.

Colorectal cancer is the third most frequent type of malignancy in the United States, and the age at diagnosis is decreasing. Although the goal of screening is focused on prevention and early detection, a subset of patients inevitably presents as oncologic emergencies. Approximately 15% of patients with colorectal cancer will present as surgical emergencies, with the majority being due to either colonic perforation or obstruction. Patients presenting with colorectal emergencies are a challenging cohort, as they often present at an advanced stage with an increase in T stage, lymphovascular invasion, and metachronous liver disease.

Gastrointestinal perforation associated with bevacizumab in metastatic colorectal cancer.

OBJECTIVE: To investigate the risk factors for gastrointestinal perforation in metastatic colorectal cancer patients receiving bevacizumab. METHODS: We retrospectively reviewed 217 patients with metastatic colorectal cancer receiving bevacizumab to investigate the risk factors for gastrointestinal perforation. Three patients occurred intestinal perforation after receiving bevacizumab. We analyzed the clinical characteristics of three patients with intestinal perforation. RESULTS: All patients receiving bevacizumab. Three of 217 patients occurred intestinal perforation after receiving bevacizumab. Patient no. 1 was 70 years old, female, having history of intestinal obstruction. The patient occurred intestinal perforation and ultimately died after receiving bevacizumab. Patient no. 2 was 59 years old, female, having history of intestinal obstruction. The patient occurred intestinal perforation after receiving bevacizumab, and recovered smoothly after symptomatic treatment. Patient no. 3 was 60 years old, female, having history of intestinal obstruction. The patient occurred intestinal perforation and ultimately died after receiving bevacizumab. CONCLUSIONS: Patients with advanced colorectal cancer receiving bevacizumab are at risk of gastrointestinal perforation. The patient's age, gender and history of bowel obstruction may be associated with gastrointestinal perforation.

Jejunal perforation and septic abdomen resulting from a choristoma in a dog.

A 4.6-year-old spayed female German shepherd dog was admitted to a specialty hospital emergency service upon referral for suspected gastrointestinal foreign body obstruction. Free abdominal fluid was collected, and results of cytologic evaluation were consistent with a septic abdomen. An abdominal barium study revealed free gas and intraperitoneal barium, along with an obstructive gas pattern within the small bowel. Ultrasonography revealed a full-thickness jejunal perforation. On exploratory laparotomy, the perforation was noted to be located mid-jejunum with no associated mass or foreign material. A resection and anastomosis were completed. Histopathologic evaluation of the affected jejunal tissue showed aberrant gastric glandular epithelium consistent with a gastric choristoma, or heterotopic gastric tissue. Key clinical message: Clinicians should consider gastric glandular choristoma as a differential diagnosis in cases of seemingly idiopathic small intestinal perforation with no known cause (i.e., foreign body penetration, neoplasia, NSAID use), and histopathologic evaluation should always be done to obtain a definitive diagnosis.

Perforation jéjunale et abdomen septique résultant d'un choristome chez un chien. Une chienne berger allemand stérilisée âgée de 4,6 ans a été admise dans le service d'urgence d'un hôpital spécialisé après avoir été référée pour une suspicion d'obstruction gastro-intestinale par un corps étranger. Du liquide abdominal libre a été prélevé et les résultats de l'évaluation cytologique étaient compatibles avec un abdomen septique. Un examen abdominal à l'aide de baryum a révélé du gaz libre et du baryum intrapéritonéal, ainsi qu'un patron de gaz obstructif dans l'intestin grêle. L'échographie a révélé une perforation sur toute l'épaisseur jéjunale. Lors d'une laparotomie exploratoire, il a été constaté que la perforation était située au milieu du jéjunum, sans masse ni corps étranger associé. Une résection et une anastomose ont été réalisées. L'évaluation histopathologique du tissu jéjunal affecté a montré un épithélium glandulaire gastrique aberrant compatible avec un choristome gastrique ou un tissu gastrique hétérotopique.Message clinique clé :Les cliniciens doivent considérer le choristome glandulaire gastrique comme diagnostic différentiel dans les cas de perforation de l'intestin grêle apparemment idiopathique sans cause connue (i.e. pénétration d'un corps étranger, néoplasie, utilisation d'AINS), et une évaluation histopathologique doit toujours être effectuée pour obtenir un diagnostic définitif.(Traduit par Dr Serge Messier).

Outcomes for pediatric acute lymphoblastic leukemia patients with intestinal perforation.

OBJECTIVES: Intestinal perforation during acute lymphoblastic leukemia (ALL) treatment in children is rare, but represents a severe complication with possible long-term consequences. In this study, we aim to provide an overview of the epidemiology and clinical characteristics of these patients; analyze surgical pathology findings for possible causes; and determine its impact on patients' therapy, nutritional status, and outcome. STUDY DESIGN: Historical chart review from January 2000 to October 2020 of children with ALL and intestinal perforation during therapy diagnosed at a single institution. Data collected included patient demographics, anthropometric measurements, ALL characteristics, diagnosis and surgery of intestinal perforation, pathology, adjustments to treatment plan, and outcome. RESULTS: Of 1840 ALL patients, 13 (0.7%) presented with intestinal perforation during treatment. Perforation occurred during induction phase in 91% of cases. Most patients underwent laparotomy with ostomy creation, and no patient died from the intervention or developed malnutrition. Pathology mainly revealed inflammation at the perforation site. Two samples showed leukemic infiltration and presence of microorganisms. Patients were able to resume ALL therapy in all cases. A total of eight patients (73%) were in first remission at last follow-up, with a median follow-up time of 42 months (interquartile range = 42). CONCLUSION: Early surgical intervention is a successful treatment approach for intestinal perforation in ALL patients. There is a clear predilection for induction phase in the occurrence of intestinal perforation in ALL patients. No specific cause was identified. Patients can receive bridging chemotherapy during surgical recovery and proceed with their treatment without apparent impact on outcome.

Acute abdominal perforation as a clinical presentation of coeliac disease.

Intestinal perforation is described in coeliac disease in the setting of refractoriness or Enteropathy-Associated T-cell Lymphoma (EATL). We report the case of a man with untreated coeliac disease who presented intestinal perforation and was diagnosed with EATL over one year later.

[Surgical treatment of a patient with tubular colonic duplication complicated by perforation and peritonitis]. / Uspeshnoe lechenie patsienta s tubulyarnoi duplikatsiei tolstoi kishki, oslozhnennoi perforatsiei i peritonitom.

We present successful treatment of a patient with tubular colonic duplication complicated by fecal impaction, perforation and fecal peritonitis. This anomaly is usually detected in children younger 2 years old. In adulthood, this diagnosis is of a precedent-setting nature. If the diagnosis was not confirmed in early childhood, the absence of typical clinical picture, long-term course of disease and difficult interpretation of clinical data complicate subsequent verification of congenital anomaly. Only infectious complications and emergency surgery in adults can make a correct diagnosis.

Case report: a case report and literature analysis on intestinal tuberculosis intestinal perforation complicated by umbilical intestinal fistula and bladder ileal fistula.

BACKGROUND: Intestinal tuberculosis is a chronic and specific infection caused by Mycobacterium tuberculosis invading the intestine. Due to the nonspecific clinical presentation, it is stressed that intestinal perforation complicates umbilical intestinal fistula and bladder ileal fistula is very rare and extremely difficult to be diagnosed. It is significant to identify the disease and take urgent intervene in the early stage. CASE PRESENTATION: An 18-month-old boy patient presented with abdominal pain. Abdominal CT suggested abscess formation in the right lower abdomen and pelvis. The patient underwent resection of necrotic and stenotic intestinal segments with the creation of an ileostomy, cystostomy and vesicoureteral fistula repair for the presence of intestinal perforation complicated by vesicoureteral fistula and umbilical enterocutaneous fistula. Histopathology confirmed the intestinal tuberculosis. The patient was discharged successfully after 11 days post anti-tuberculosis treatment. CONCLUSION: Our case report here is a rare case of umbilical intestinal fistula with bladder ileal fistula secondary to intestinal perforation from intestinal tuberculosis. The purpose of this report is to make the surgical community aware of atypical presentations of intestinal tuberculosis. If our peers encounter the similar situation, they can be prepared for corresponding diagnosis and treatment.

Malignant Atrophic Papulosis Presenting with Intestinal Perforation: A Case Report.

Malignant atrophic papulosis sometimes known as Degos' disease is an idiopathic, uncommon condition with fewer than 200 occurrences documented. It is a chronic thrombo-obliterative vasculopathy characterised by papular skin lesions with a core porcelain-white atrophy and a surrounding telangiectatic border. We report a 15-year-old male patient with a recurrent history of hollow viscus perforation, which was managed on all the occasions with exploratory laparotomy and primary perforation repair. Additionally, the patient had a five month history of numerous, non-itchy, atrophic papules with a core porcelain-like area and hyperkeratotic margins, characteristic of Degos' disease. The only basis for diagnosis is the distinctive skin lesions with biopsy. Along with systemic lupus erythematosus and other connective tissue diseases, tuberculosis must also be taken into account while assessing the clinical presentation of malignant atrophic papulosis. There is currently no known treatment for malignant atrophic papulosis that has been effective. Keywords: case reports; intestinal perforation; malignant atrophic papulosis; ulcer; vasculitis.

Bowel perforation associated with Cushing's disease: a case report with literature review.

Although rare, endogenous hypercortisolemia, including Cushing's disease (CD), is known to cause bowel perforation and to mask typical symptoms of bowel perforation, leading to delayed diagnosis. Additionally, elderly patients with CD are considered to be at a higher risk for bowel perforation because intestinal tissue fragility tends to increase in the elderly. Herein, we describe a rare case in which a young adult patient with CD was diagnosed with bowel perforation associated with CD following severe abdominal pain. A 24-year-old Japanese man was admitted to the hospital for the evaluation of ACTH-dependent Cushing's syndrome. He suddenly complained of severe abdominal pain on the 8th day of hospitalization. Computed tomography revealed free air around the sigmoid colon. The patient was diagnosed with bowel perforation, underwent emergency surgery, and was saved. He was subsequently diagnosed with CD, and the pituitary adenoma was resected transsphenoidally. To date, eight cases of bowel perforation due to CD had been reported, with a median age of 61 years at the time of bowel perforation. Hypokalemia was detected in half of the patients, and all had a history of diverticular disease. Nevertheless, not many patients complained of peritoneal irritation. In conclusion, this is the youngest reported case with bowel perforation due to CD and the first report of bowel perforation in a patient without a history of diverticular disease. Bowel perforation may occur in patients with CD, irrespective of age and the presence of hypokalemia, diverticular disease, or peritoneal irritation.

Report of a case mimicking the acute appendicitis; Small bowel perforation due to olive leaf.

Abdominal pain is one of the most frequent causes of emergency room admissions. Acute appendicitis is the most common surgical pathology in these patients. Foreign body ingestion is a quite rare pathology that takes place in list of differential diagnosis of acute appendicitis. We presented a dry olive leaf ingestion case in this paper.

Surgical management of necrotising enterocolitis in Sweden: A national cohort study.

AIM: Necrotising enterocolitis (NEC) is the dominating surgical emergency in preterm neonates. The aims were to investigate indications, surgical management and mortality for surgically treated neonates with NEC. METHODS: Data were retrieved from the Swedish Neonatal Quality Register for Swedish neonates with surgically treated NEC from 1 January 2017 to 31 December 2021. Diagnosis was validated by surgical records and histopathology. Neonates with isolated spontaneous intestinal perforation were excluded. RESULTS: In total, 109 neonates were included. Median gestational age was 25 weeks (22-38), and median birth weight was 771 g (269-3920). Preoperative pneumoperitoneum was found in 32%, portal venous gas in 25% and clinical deterioration on conservative treatment in 26% of the neonates. Among the 97 neonates presenting with small bowel necrosis, single-focal NEC occurred in 38 (39%), multifocal NEC in 35 (36%) and panintestinal NEC in 24 (25%). A primary anastomosis was performed in 10/87 (11%) of the neonates with bowel resection at primary surgery. Clip-and-drop technique was applied in 24/87 (28%).Mortality rate was 37%. CONCLUSION: Mortality was well comparable with earlier reports considering exclusion of spontaneous intestinal perforation (SIP) and the low gestational age of the study population. Resection of necrotic bowel with stoma formation was the dominating surgical method.

Iatrogenic duodenal diverticulum perforation: a systematic review.

BACKGROUND: Duodenal diverticulum occurs in approximately 20% of the population and can lead to life-threatening complications such as perforation. Most perforations are secondary to diverticulitis, with iatrogenic causes being exceptionally rare. This systematic review explores the aetiology, prevention and outcomes of iatrogenic perforation of duodenal diverticulum. METHODS: A systematic review was performed according to the PRISMA guidelines. Four databases were searched, including Pubmed, Medline, Scopus and Embase. The primary data extracted were clinical findings, type of procedure, prevention and management of perforation and outcomes. RESULTS: Forty-six studies were identified, of which 14 articles met inclusion criteria and comprised 19 cases of iatrogenic duodenal diverticulum perforation. Four cases identified duodenal diverticulum pre-intervention, nine were identified peri-intervention, and the remainder were identified post-intervention. Perforation secondary to endoscopic retrograde cholangiopancreatography (n = 8) was most common, followed by open and laparoscopic surgery (n = 5), gastroduodenoscopy (n = 4) and other (n = 2). Operative management with diverticulectomy was the most frequent treatment (63%). Iatrogenic perforation was associated with 50% morbidity and 10% mortality. CONCLUSION: Iatrogenic perforation of duodenal diverticulum is exceptionally rare and associated with high morbidity and mortality. There are limited guidelines surrounding standard perioperative steps to prevent iatrogenic perforations. A review of preoperative imaging helps identify potential aberrant anatomy, such as a duodenal diverticulum, to allow for recognition and prompt management initiation in the event of perforation. Intraoperative recognition and immediate surgical repair are safe options for this complication.

Two cases of Clostridium ramosum bacteremia with intestinal perforation: The antimicrobial susceptibility of clinical strains.

Clostridium ramosum is one of the obligate anaerobes that constitute the intestinal microbiota, and one of the rare Clostridia. With Clostridium ramosum, very few data have been reported to investigate antimicrobial susceptibility for clinical isolates that have caused bacteremia. Here, we report two cases of Clostridium ramosum bacteremia. The first case was a 54-year-old Japanese man with taking 20mg hydrocortisone for hypopituitarism. He presented to the emergency department for an unknown cause cardiopulmonary arrest. At the hospital day 36, he had fever and a drop in blood pressure. Abdomen computed tomography (CT) revealed free air around the ascending colon, we diagnosed with intestinal perforation, and peritonitis. Blood culture revealed Clostridium ramosum. We administered conservative management by 6-week of antibiotic treatment. The second case was a 78-year-old Japanese man with no significant medical history. He was referred to our hospital with fever and abdominal pain. Abdomen CT revealed perforated appendicitis, and blood cultures revealed Clostridium ramosum. We performed emergency surgery, and administered one-week course of antibiotic treatment. This report demonstrates two cases of Clostridium ramosum bacteremia with intestinal perforation, and the antimicrobial susceptibility of each clinical strain. For the future, it is necessary to accumulate data on the susceptibility of clinical isolates in order to find an appropriate treatment.

Indications for Operative Management of Complicated Duodenal Diverticula: A Review.

The duodenum is the second most common location for a diverticulum to form after the colon. These duodenal diverticula (DD) are often found incidentally and rarely require intervention. In recent years, surgical management has been restricted to patients with significant complicated sequelae, such as perforation, abscess, or fistula formation. We present the rare case of a perforated broad-based diverticulum in the third portion of the duodenum necessitating surgical correction. The patient presented with persistent symptoms following failure of conservative management and underwent surgical resection. Due to difficulty visualizing the extent of the diverticulum, a novel intraoperative technique of bowel insufflation via nasogastric tube was used allowing for elucidation of the diverticular borders and complete resection. Although DD are common, there exists no consensus on when operative intervention is indicated. Given that significant morbidity and mortality can be associated with symptomatic DD, a systematic way to guide management decisions is needed. After conducting a review of the literature, we propose that the modified Hinchey classification can be used not only to categorize duodenal diverticulitis but to guide treatment choice in cases with unclear risk benefit profiles.

Intestinal perforation after intravitreal low dose ranibizumab injection for the treatment of type 1 retinopathy of prematurity: A case report.

PURPOSE: To report a newborn patient with gastrointestinal (GIS) perforation after intravitreal ranibizumab (RBZ) treatment. CASE REPORT: The patient was born at 31 gestational week and hospitalized with the diagnosis of small for gestational age and prematurity. In the follow up he underwent GIS surgery due to necrotizing enterocolitis (NEC) and was diagnosed with retinopathy of prematurity (ROP). At 43 weeks of postmenstrual age, he developed intestinal perforation after 12 h of the second low-dose RBZ injection. According to our knowledge, this is the first report of GIS perforation due to low-dose intravitreal RBZ treatment in an infant with severe ROP. CONCLUSION: The risk of GIS perforation should be taken into consideration during the application of intravitreal vascular endothelial growth factor antagonist agents, especially in newborns with previous GIS surgery and a history of NEC, and these patients should be carefully monitored for GIS complications.

Metastatic melanoma causing small intestinal perforation at the jejunojejunostomy after Roux-en-Y gastric bypass: a case report.

BACKGROUND: Metastatic melanoma of the small intestine is relatively common, and among affected patients, the proportion with involvement of the small intestine ranges from 35% to 70%. Small intestinal perforation as a primary manifestation of metastatic melanoma is rare. We present the exceptional case of a perforation at the jejunojejunostomy after Roux-en-Y gastric bypass caused by metastatic melanoma. CASE PRESENTATION: A 59-year-old woman with a history of a laparoscopic Roux-en-Y gastric bypass and toe amputation due to malignant melanoma (stadium IIIC) presented with an acute abdomen. The abdominal computed tomography scan showed a covered perforation at the jejunojejunostomy of the gastric bypass. The patient underwent an urgent surgical exploration revealing massive tumoral invasion of the anastomosis. The tumoral mass and anastomosis were resected and a new jejunojejunostomy was created. Histopathological examination identified the tumor as a malignant melanoma, so the current abdominal lesions were presumed to be metastases. The postoperative course was uneventful and adjuvant immunotherapy was started a week later. One year after surgery she was doing well with maintenance immunotherapy and there was no evidence of recurrent metastatic disease. CONCLUSION: We report the first case of a perforation at the jejunojejunostomy after Roux-en-Y gastric bypass caused by metastatic melanoma. This exceptional case illustrates that a history of malignant melanoma in case of an acute abdomen should raise suspicion of possible metastatic disease.

A case of HCC successfully treated with infliximab-steroid sequential therapy for small bowel perforation due to atezolizumab/bevacizumab combination therapy.

BACKGROUND: Although reports of gastrointestinal perforation after immune-related adverse events (irAE) enteritis are rare, the anti- vascular endothelial growth factor (VEGF) effect of bevacizumab may be involved in gastrointestinal perforation. We report a rare case of gastrointestinal perforation in a patient with hepatocellular carcinoma treated with atezolizumab/bevacizumab combination therapy and infliximab before steroid use. CASE: A 72-year-old man, who received seven courses of atezolizumab/bevacizumab for hepatocellular carcinoma due to hepatitis B, was admitted to our department with idiopathic abdominal pain and diarrhea (grade 2 [G2]). Computed tomography (CT) and colonoscopy confirmed edema in the gastrointestinal tract. Perforation of the jejunum was observed in a CT performed on the third day and an emergency operation was performed. Intraoperative findings showed severe edema of the jejunum and leakage of feces into the abdominal cavity. The patient was diagnosed with irAE enteritis comprehensively with severe wall thickening on CT and colonoscopy, negative stool culture, and pathological findings of CD8-positive cells. Infliximab was administered before initiating steroids, to prevent reperforation. The enteritis improved by the 22nd day; however, CT performed on the 35th day of illness showed relapse of gastrointestinal wall thickening and G2 diarrhea symptoms; therefore, prednisolone (PSL) 60 mg/day was started on the 36th day of illness. After introducing PSL, enteritis did not reoccur, and the patient was discharged on the 63rd day of illness after admission. CONCLUSION: There are no reports of gastrointestinal perforation by atezolizumab/bevacizumab for hepatocellular carcinoma, and prior administration of infliximab. We therefore report the clinical course and management.

Coexistence of Colon Perforation and Congenital Lipodystrophy.

Lipodystrophy (LD) is an acquired or congenital rare condition consisting of hyperlipidaemia, glucose intolerance/ insulin resistance, and almost complete absence and storage of adipose tissue. Colon perforations can be observed in type 4 congenital LD. Here, we aimed to present a case of sigmoid colon perforation which developed in a young woman with the diagnosis of LD. Extensive purulent peritonitis, significant wall thickening, and oedema in the sigmoid colon were detected during surgical exploration. Anterior resection with end colostomy procedure was then performed. Although bowel perforation has been theoretically reported to occur in LD, the presented case is the first adult patient in the literature. These individuals tend to develop colon perforation as a result of histological changes in their gastrointestinal tract. This situation should always be taken into consideration in order to avoid delay in diagnosis, especially in patients who present with abdominal pain and have a history of LD. Key Words: Intestinal perforation, Congenital lipodystrophy, Peritonitis, Sigmoid colon.
