Small intestine angioleiomyoma as a rare cause of perforation:A case report

BACKGROUND Angioleiomyoma is a rare and benign stromal tumor typically found in subcutaneous tissue.It rarely occurs in the gastrointestinal tract.Among the reported cases,the most common complication was gastrointestinal bleeding.Perforation has only been reported as a complication in the last few decades.CASE SUMMARY This case report detailed the discovery of intestinal angioleiomyoma in a 47-yearold male presenting with abdominal pain that had persisted for 3 d.After suspecting hollow organ perforation,surgical intervention involving intestinal resection and anastomosis was performed.CONCLUSION The report underscores the significance of early surgical intervention in effectively treating angioleiomyoma while emphasizing the pivotal role of timely and appropriate measures for favorable outcomes.

Unusual case of emphysematous cystitis mimicking intestinal perforation:A case report

BACKGROUND Emphysematous cystitis(EC)is a bladder condition commonly caused by gasgenerating bacterial infections.Factors that increase the risk for developing this condition include female gender,age≥60 years,and diabetes mellitus,glycosuria,and urinary stasis.The symptoms of EC often lack specificity,making diagnostic imaging techniques crucial for accurate identification of the condition.CASE SUMMARY This report presents an unusual case of EC that mimicked intestinal perforation.While it was initially challenging to differentiate between intestinal perforation and EC on admission,the patient managed to avoid unnecessary surgery and made a good recovery solely through antibiotic treatment.CONCLUSION Successful treatment of the patient described herein highlights the importance of accurately diagnosing EC,which can be difficult to differentiate from intestinal perforation.

Colon perforation with severe peritonitis caused by erotic toy insertion and treated using vacuum-assisted closure:A case report

BACKGROUND Colorectal foreign bodies are commonly encountered during surgery.They are frequently observed in men 20 to 90 years of age and have bimodal age distribution.Surgical management is necessary for cases of rectal perforation.However,surgical site infections are the most common complications after colorectal surgery.CASE SUMMARY We discuss a case of rectal perforation in a patient who presented to our hospital 2 d after its occurrence.The perforation occurred as a result of the patient inserting a sex toy in his rectum.Severe peritonitis was attributable to delayed presentation.CONCLUSION Vacuum-assisted closure was performed to treat the wound,which healed well after therapy.No complications were noted.

Appendicitis combined with Meckel’s diverticulum obstruction, perforation, and inflammation in children: Three case reports

BACKGROUND Meckel’s diverticulum is a common congenital malformation of the small intestine,with the three most common complications being obstruction,per-foration,and inflammation.To date,only a few cases have been reported world-wide.In children,the clinical symptoms are similar to appendicitis.As most of the imaging features are nonspecific,the preoperative diagnosis is not precise.In addition,the clinical characteristics are highly similar to pediatric acute appendicitis,thus special attention is necessary to distinguish Meckel’s diver-ticulum from pediatric appendicitis.Patients with poor disease control should undergo laparoscopic exploration to avoid serious complications,including intestinal necrosis,intestinal perforation and gastrointestinal bleeding.CASE SUMMARY This report presents three cases of appendicitis in children combined with intestinal obstruction,which was caused by fibrous bands(ligaments)arising from the top part of Meckel's diverticulum,diverticular perforation,and diver-ticular inflammation.All three patients,aged 11-12 years,had acute appendicitis as their initial clinical presentation.All were treated by laparoscopic surgery with a favorable outcome.A complete dataset including clinical presentation,dia-gnostic imaging,surgical information,and histopathologic findings was also provided.CONCLUSION Preoperative diagnosis of Meckel’s diverticulum and its complications is challenging because its clinical signs and complications are similar to those of appendicitis in children.Laparoscopy combined with laparotomy is useful for diagnosis and treatment.

Gastrointestinal perforation in metastatic colorectal cancer patients with peritoneal metastases receiving bevacizumab

AIM:To investigate the safety and efficacy of adding bevacizumab to first-line chemotherapy in metastatic colorectal cancer patients with peritoneal disease.METHODS:We compared rates of gastrointestinal perforation in patients with metastatic colorectal cancer and peritoneal disease receiving first-line chemotherapy with and without bevacizumab in three distinct cohorts:(1) the AGITG MAX trial(Phase Ⅲ randomised clinical trial comparing capecitabine vs capecitabine and bevacizumab vs capecitabine,bevacizumab and mitomycin C);(2) the prospective Treatment of Recurrent and Advanced Colorectal Cancer(TRACC) registry(any first-line regimen ± bevacizumab);and(3) two cancer centres in New South Wales,Australia [Macarthur Cancer Therapy Centre and Liverpool Cancer Therapy Centre(NSWCC) from January 2005 to Decenber 2012,(any first-line regimen ± bevacizumab).For the AGITG MAX trial capecitabine was compared to the other two arms(capecitabine/bevacizumab and capecitabine/bevacizumab/mitomycin C).In the AGITG MAX trial and the TRACC registry rates of gastrointestinal perforation were also collected in patients who did not have peritoneal metastases.Secondary endpoints included progression-free survival,chemotherapy duration,and overall survival.Time-toevent outcomes were estimated using the Kaplan-Meier method and compared using the log-rank test.RESULTS:Eighty-four MAX,179 TRACC and 69 NSWCC patients had peritoneal disease.There were no gastrointestinal perforations recorded in either the MAX subgroup or the NSWCC cohorts.Of the patients without peritoneal disease in the MAX trial,4/300(1.3%) in the bevacizumab arms had gastrointestinal perforations compared to 1/123(0.8%) in the capecitabine alone arm.In the TRACC registry 3/126(2.4%) patients who had received bevacizumab had a gastrointestinal perforation compared to 1/53(1.9%) in the chemotherapy alone arm.In a further analysis of patients without peritoneal metastases in the TRACC registry,the rate of gastrointestinal perforations was 9/369(2.4%) in the chemotherapy/bevacizumab group and 5/177(2.8%) in the chemotherapy alone group.The addition of bevacizumab to chemotherapy was associated with improved progression-free survival in all three cohorts:MAX 6.9 m vs 4.9 m,HR = 0.64(95%CI:0.42-1.02);P = 0.063;TRACC 9.1 m vs 5.5 m,HR = 0.61(95%CI:0.37-0.86);P = 0.009;NSWCC 8.7 m vs 6.8 m,HR = 0.75(95%CI:0.43-1.32);P = 0.32.Chemotherapy duration was similar across the groups.CONCLUSION:Patients with peritoneal disease do not appear to have an increased risk of gastrointestinal perforations when receiving first-line therapy with bevacizumab compared to systemic therapy alone.

Henoch-Schonlein purpura from vasculitis to intestinal perforation: A case report and literature review

Henoch-Sch?nlein purpura(HSP) is generally a selflimited vasculitis disease and has a good prognosis. We report a 4-year-old Thai boy who presented with palpable purpura, abdominal colicky pain, seizure, and eventually developed intestinal ischemia and perforation despite adequate treatment, including corticosteroid and intravenous immunoglobulin therapy. Imaging modalities, including ultrasonography and contrastenhanced computed tomography, could not detect intestinal ischemia prior to perforation. In this patient, we also postulated that vasculitis-induced mucosal ischemia was a cause of the ulcer, leading to intestinal perforation, and high-dose corticosteroid could have been a contributing factor since the histopathology revealed depletion of lymphoid follicles. Intestinal perforation in HSP is rare, but life-threatening. Close monitoring and thorough clinical evaluation are essential to detect bowel ischemia before perforation, particularly in HSP patients who have hematochezia, persistent localized abdominal tenderness and guarding. In highly suspicious cases, exploratory laparotomy may be needed for the definite diagnosis and prevention of further complications.

Perforation of the colon by invading recurrent gastrointestinal stromal tumors during sunitinib treatment

The molecular targets of sunitinib are receptor tyrosine kinases (RTKs),and this drug has also been known to exert blocking effects on the activation of KIT,which is similar to the mechanism of action of imatinib. Moreover,sunitinib has an additional anti-angiogenic effect through its inhibition of the vascular endothelial growth factor receptor activation. We report here a 70-year-old patient diagnosed with a recurrent gastrointestinal stromal tumor (GIST),which invaded the transverse colon and led to a perforation during sunitinib treatment. A computed tomography scan and 3-dimensional reconstruction showed necrosis of the recurrent hepatic mass and perforation of the invaded transverse colon. After percutaneous drainage of the intraperitoneal abscess,antibiotic treatment and restricted diet,the condition of the patient improved. The present case is the first to report that sunitinib,which is administered to treat GIST resistant to imatinib,can cause unexpected colon perforation and subsequent peritonitis.

Intestinal perforation as an early complication in Wegener's granulomatosis

We present the case of a young man with involvement of the gastrointestinal tract in the early phase of Wegener's granulomatosis. The patient presented at the emergency department with sudden onset of abdominal pain, nausea and vomiting. Radiography work up was negative for free air although ultrasound examination showed extraluminal intra-abdominal fluid. Exploratory laparotomy showed perforation of the jejunum. The bowel was vital except for this small segment of jejunum. A 5-cm long segment of jejunum was resected which revealed ulcerative inflammation accompanied by occluded arteries of the small intestine. Although intestinal perforation in Wegener's granulomatosis is uncommon, several cases have been previously reported. Intestinal involvement in the early phase of the disease is even more uncommon. This case combined with prev iously reported cases emphasizes the possibility of gastrointestinal manifestation early in Wegener's disease.

Outcome of surgical treatment of intestinal perforation in typhoid fever

AIM:To represent our clinical experience in the treatment of intestinal perforation arising from typhoid fever.METHODS:The records of 22 surgically-treated patients with typhoid intestinal perforation were evaluated retrospectively.RESULTS:There were 18 males and 4 females,mean age 37 years(range,8-64 years).Presenting symptoms were fever,abdominal pain,diarrhea or constipation.Sixteen cases were subjected to segmental resection and end-to-end anastomosis,while 3 cases received 2-layered primary repair following debridement,one case with multiple perforations received 2-layered primary repair and end ileostomy,one case received segmental resection and end-to-end anastomosis followed by an end ileostomy,and one case received segmental resection and end ileostomy with mucous fistula operation.Postoperative morbidity was seen in 5 cases and mortality was found in one case.CONCLUSION:Intestinal perforation resulting from Salmonella typhi is an important health problem in Eastern and Southeastern Turkey.In management of this illness,early and appropriate surgical intervention is vital.

Perforation of metastatic melanoma to the small bowel with simultaneous gastrointestinal stromal tumor

The gastrointestinal tract (GIT) is a common site of metastases for malignant melanoma. These metastatic tumors are often asymptomatic. We describe a case of a 58-year-old male who presented with a sudden onset of generalized abdominal pain. The patient's past medical history was significant for lentigo melanoma of the right cheek. Laparotomy was performed and two segments ofsmall bowel, one with a perforated tumor, the other with a non-perforated tumor, were removed. Histology and immunohistochemical staining revealed the perforated tumor to be a metastatic malignant melanoma and the non-perforated tumor was found to be a gastrointestinal stromal tumor (GIST). The patient was discharged 7 d postoperatively. To the best of our knowledge, this is the first reported case in the literature of a simultaneous metastatic malignant melanoma and a GIST. Surgical intervention is warranted in patients with symptomatic GIT metastases to improve the quality of life or in those patients with surgical emergencies.

Typhoid intestinal perforation in developing countries: Still unavoidable deaths?

Typhoid fever is a public health challenge mostly concentrated in impoverished, overcrowded areas of the developing world, with lack of safe drinking and sanitation. The most serious complication is typhoid intestinal perforation(TIP), observed in 0.8% to 39%, with a striking rate difference between high-income and low-middle-income countries. Although the mortality rate consequent to TIP in resource-poor countries is improved in the last decades, it is still fluctuating from 5% to 80%, due to surgical-and not surgical-related constraints. Huge economic costs and long timelines are required to provide a short-to middle-term solution to the lack of safe water and sanitation. Inherent limitations of the currently available diagnostic tools may lead to under-evaluation as well as over-evaluation of the disease, with consequent delayed treatment or inappropriate, excessive antibiotic use, hence increasing the likelihood of bacterial resistance. There is a need for immunization programs in populations at greatest risk, especially in sub-Saharan Africa. Uniform surgical strategies and guidelines, on the basis of sound or prospective surgical studies and adapted to the local realities, are still lacking. Major drawbacks of the surgical treatment are the frequent delays to surgery, either for late diagnosis or for difficult transports, and the unavailable appropriate intensive care units in most peripheral facilities. As a consequence, poor patient's conditions at presentation, severe peritoneal contamination and unsuitable postoperative care are the foremost determinant of surgical morbidity and mortality.

Small Intestinal Perforation Caused by Metastasis from Squamous Cell Carcinoma of Scalp --One Case Report

The small bowel metastases from head and neck regions are extremely rare. The diagnosis and treatment of such kind of small bowel metastases remain unclear. This paper reports on a 53-year-old case with small intestine perforation caused by metastasis from squamous cell carcinoma of scalp. After surgical treatment, the patient had a relatively better survival. This paper shares the clinical experience we have learned from managing this patient in hope that it will help other medical professionals in oncology to recognize the disease.

Intestinal perforation with abdominal abscess caused by extramedullary plasmacytoma of small intestine: A case report and literature review

BACKGROUND Extramedullary plasmacytoma(EMP)of the gastrointestinal tract is an extremely rare disease.Clinical manifestations of EMPs are varied and depend on the location and progression of the tumor.CASE SUMMARY Here,we firstly report a case of intestinal perforation with abdominal abscess caused by EMP of the small intestine in a 55-year-old female patient.The patient received emergency surgery immediately after the necessary preoperative procedures.During the operation,EMP was found to have caused the perforation of the small intestine and the formation of multiple abscesses in the abdominal cavity.Partial resection of the small intestine with peritoneal irrigation and drainage was performed.EMP was finally confirmed by postoperative histopathology and laboratory tests.Additionally,we performed a literature review of gastrointestinal EMP to obtain a deeper understanding of this disease.CONCLUSION EMP of the small intestine may have spontaneous perforation,which requires emergency surgery.Surgical resection can obtain good therapeutic effects.

About a rare cause of intestinal perforation

Background: Periarteritis nodosa (PAN) is a necrotizing systemic vasculitis involving mediumsized arteries and rarely the smallsized ones. It affects various organs and is generally revealed by different non specific organs. The aim of the authors is to report a rare revealing manifestation of this disease which is the perforation of the small bowel and to highlight the most important histological features. Case report: The authors describe the case of a 48-year-old Caucasian woman, without a particular past medical history, who presented an acute surgical abdomen. A surgical exploration was decided and showed a necrosis of the small bowel and the appendix. A segmental ileectomy was performed. The histological examination of the specimen showed small vasculitis-affected with fibroid necrosis dealing to the diagnosis of intestinal perforation caused by a PAN was retained. Post-operatively, the patient was put on immunosuppressive therapy and presented a prolonged healing process and was discharged from the hospital 20 days after her admission. Conclusion: Although it is rare for PAN to be revealed by small bowel perforation, it should be kept in mind when facing ischemic change of the small bowel.

Free perforation of the small intestine in collagenous sprue

A 67-year-old man with celiac disease developed recurrent diarrhea,profound weakness and weight loss, with evidence of marked protein depletion.His clinical course was refractory to a strict gluten-free diet and steroid therapy.Postmortem studies led to definition of unrecognized collagenous sprue that caused ulceration and small intestinal perforation.Although PCR showed identical monoclonal T-cell populations in antemortem duodenal biopsies and postmortem jejunum,careful pathological evaluation demonstrated no frank lymphoma.Rarely,overt or even cryptic T-cell lymphoma may complicate collagenous sprue,however, small intestinal ulcers and perforation may also develop independently.The dramatic findings here may reflect an underlying or early molecular event in the eventual clinical appearance of overt T-cell lymphoma.

Intestinal Invagination in Adults: About a Case at the “Mother-Child” Hospital Le Luxembourg in Mali

Intussusception is a pathology of infants and young children. Its occurrence in adults is very unusual. In the vast majority of cases, it is secondary to a benign or malignant tumor. Small bowel malignancies are relatively rare, 1% - 5% of malignant tumors of the gastrointestinal tract. Acute intussusception, a rare pathology in adults, often presents with non-specific symptoms. Contrary to children, the organic origin remains preponderant in the elderly, where the origin of neoplasia must be suspected in first intention. We report the case of a 49-year-old patient admitted urgently from the Luxembourg “Mère Enfant” hospital center in Bamako, Mali, for an occlusive syndrome. Several abdomino-pelvic ultrasounds were performed in several clinics with mixed conclusions: Hydro-aeric distension and a cessation of matter and gas without a clearly visible mass (04/09/2022);Demonstration of the central hydro-aeric levels wider than high containing fine and regular folds corresponding to connivents whose aspect is in factor of left acute small intestine occlusion, to be completed by the surgical opinion (06/09/2022) and a third ultrasound showed a normal appearance of the liver, gallbladder, kidneys, pancreas, spleen, bladder and prostate;diffuse aero-colic distention without lesion of secondary appearance (21/11/2022). A frontal standing ASP dated 11/25/2022 showed hail-like hydro-aeric levels. Surgical management consisted of an open oncological resection of an obstructive bowel tumor with ileo-ileal invagination. The anatomopathological and immunohistochemical study of the surgical specimen concluded to diffuse small cell non-Hodgkin’s lymphoma, without vascular embolism. The resection limits pass into the healthy zone.

A Rare Cause of Pneumoperitoneum: Perforated Gastrointestinal Stromal Tumor (GIST)

Gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor and has a malignant potential. The clinical presentation with pneumoperitoneum and peritonitis is extremely rare. We report a case of a 40-year-old male presented with symptoms of acute abdomen. Radiological work-up confirmed pneumoperitoneum. Emergency laparatomy and complete resection were performed. The final diagnosis revealed perforated GIST originating from the jejunum. If an abdominal mass presents with pneumoperitoneum and peritonitis, jejunal GIST should be considered in diagnosis. A complete radical resection followed by postoperative adjuvant chemotheraphy with Imatinib is recommended.

Neonatal gastric perforation: A single center experience

AIM: To determine the etiology and prognostic factors for neonatal gastric perforation(NGP), a rare but life-threatening disease.METHODS: Between 1980 and 2011, nine patients un-derwent surgical intervention for NGP at Seoul National University Children's Hospital. The characteristics and prognosis of the patients were retrospectively analyzed.RESULTS: Among the nine patients, three(33.3%) were preterm babies and five(55.5%) had associated anomalies, which included diaphragmatic eventration(n = 2), congenital diaphragmatic hernia, esophageal atresia with tracheoesophageal fistula, and antral web. Three(33.3%) patients were born before 1990 and three(33.3%) had a birth weight < 2500 g. Pneumo-peritoneum was found on preoperative images in six(66.7%) patients, and incidentally in the other three(33.3%) patients. Surgery was performed within 24 h after the onset of symptoms in seven(77.8%) patients. The overall mortality rate was 22.2%(2/9). The time between symptoms and surgical intervention was the only prognostic factor for survival, whereas premature birth and birth weight were not.CONCLUSION: Early detection and advances in neo-natal intensive care may improve the prognosis of NGP.

Percutaneous peritoneal drainage in isolated neonatal gastric perforation

A comment on the article by He et al, "Idiopathic neonatal pneumoperitoneum with favorable outcome:A case report and review", published on World Journal of Gastroenterology that reported a case of idiopathic neonatal pneumoperitoneum, possibly due to gastric perforation, with a favorable outcome without surgical intervention.
