Management of serious complications in intra-abdominal desmoid-type fibromatosis

Role of Surgery in the Treatment of Abdominal Desmoid Fibromatosis: A Single-Center Experience

With increasing multidisciplinary management and emphasis on masterly inactivity for abdominal fibromatosis (AF), the indications for surgery are evolving. This retrospective analysis looked at outcomes following surgery. Two groups of patients who underwent surgery for AF between November 2011 and August 2021 were identified-intra-abdominal fibromatosis (IAF) and abdominal wall fibromatosis (AWF). All treatment-related details and follow-up data were gathered from a database and analyzed. Sixteen patients underwent surgery for IAF. R0 resection (wide margin) was achieved in 13 patients (81.2%). Over a median follow-up period of 51.7 (range 5-103) months, 5 patients developed recurrence (31.2%). The conditional probabilities of OS and DFS at 5 years were 80% (95% CI 58.7-100) and 42.2% (95% CI 20.3-87.8), respectively. Ten patients with AWF underwent surgery. R0 resection was achieved at 70% (7/10). Over a median follow-up period of 54.8 (range 12.9-96.7) months, 2 patients (20%) developed recurrence. The conditional probabilities of OS and DFS at 5 years were 88.9% (95% CI 70.6-100) and 77.8% (95% CI 54.9-87.8), respectively. Surgery has a vital role in the management of AF presenting with progressive/symptomatic lesions, especially when watchful waiting is not an option, and must be considered as one of the first-line active therapy. Timely curative surgery avoids disease progression and its morbidity with acceptable recurrence rates and provides durable remissions.

Case report: A rare case of desmoid-type fibromatosis originating in the small intestine

Background

Desmoid-type fibromatosis (DF) is characterized by a rare monoclonal fibroblast proliferation that exhibits variable and unpredictable clinical presentation. DF can be classified into sporadic and hereditary types. Despite extensive research efforts, the exact etiology of DF remains elusive.

Case description

A 31-year-old male patient presented to the hospital with a progressively growing mass in the right lower abdomen, accompanied by abdominal discomfort. Symptoms are discovered 1 week before admission. Enteroscopy revealed no evidence of colonic abnormalities, and blood tests did not indicate any abnormalities. Due to the indeterminate nature of the mass during surgery, a partial resection of the ileum and cecum was performed, followed by ileocolonic end-to-end anastomosis, with no postoperative complications. The final pathological diagnosis confirmed primary desmoid-type fibromatosis of the distal ileum (invasive fibromatosis). To effectively manage DF, we recommend a follow-up schedule for patients. This includes appointments every 3 months in the first year following surgery, followed by appointments every 6 months up to the fifth year, and then once a year thereafter. The follow-up examinations should include collection of the patient's medical history, physical examination, blood tests, ultrasounds, CT scans, and other relevant assessments. During the first year of the follow-up period, no further treatment was administered, and the patient remained disease-free.

Conclusion

Desmoid-type fibromatosis (DF) originating from the small intestine is an extremely rare condition that exhibits local invasiveness and can be life-threatening. Despite its benign histology, DF has a high local recurrence rate and lacks metastatic potential. Diagnosis of DF remains challenging, especially in cases where surgical intervention is not feasible due to asymptomatic patients or partial organ impairment. In such cases, a "watchful waiting" approach is recommended as the initial treatment strategy. However, when preoperative diagnosis is difficult, surgery is typically considered the best option. Given the potential for local recurrence and the uncertain long-term prognosis, regular follow-up is necessary.

Gardner syndrome: A case report

BACKGROUND

Gardner syndrome (GS) is a rare autosomal dominant hereditary disorder. Since GS often has multi-system involvement with diverse clinical manifestations, misdiagnosis is common. Herein we report a case of GS.

CASE SUMMARY

A 38 year-old women presented with intermittent abdominal distension, nausea, and vomiting for 15 mo, which was aggravated for 1 wk. Related tests showed gastrointestinal adenoma and multiple desmoid tumors in the abdominal wall and abdominal cavity, and gene sequencing confirmed the diagnosis of GS. The patient underwent endoscopic intestinal polypectomy and symptomatic treatment, and her symptoms were relieved. Later, the patient's symptoms recurred and became worse than before. Gastrointestinal anastomosis was performed, and the patient had no postoperative discomfort. Finally, her condition improved.

CONCLUSION

The clinical manifestations of GS are varied, and the appearance of extraenteral manifestations before intestinal polyps is very important for the early identification of such patients, so as to achieve early treatment and improve the prognosis.

Case report: Intra-abdominal aggressive fibromatosis: A rare cause of hyperemesis

Rationale

Aggressive fibromatosis is a rare and locally infiltrative monoclonal fibroblastic proliferation with lack of metastatic potential. We describe a rare case of intra-abdominal aggressive fibromatosis on young female with hyperemesis.

Patient concerns

A 23-year-old female was admitted with hyperemesis and loss of weight.

Diagnoses

According to imaging findings and immunohistology findings, a diagnosis of intra-abdominal aggressive fibromatosis was formulated.

Outcomes

After the surgery, no evidence of local recurrence was noted during the 6 months of follow-up.

Lessons

AF may explain why pregnant women may have severe hyperemesis.
