Adenocarcinoma of the third duodenal portion: Case report and review of literature

Signet-ring cell carcinoma of the duodenal bulb presenting with gastrointestinal hemorrhage: a case report and literature review

Background

Primary duodenal cancer (PDC) is rare, especially signet-ring cell carcinoma (SRCC) of the duodenal bulb, and it is commonly misdiagnosed as an ulceration. Here, we report a rare case of SRCC of the duodenal bulb presenting with gastrointestinal hemorrhage in an 82-year-old man.

Case presentation

An 82-year-old man was admitted for gastrointestinal hemorrhage. Physical examination revealed upper abdominal tenderness and pale appearance, but was otherwise unrevealing. Laboratory workup was significant for anemia. Imaging showed no abnormalities. Two endoscopic evaluations along with interventional embolization were attempted and, unfortunately, adequate hemostasis was not achieved, resulting in distal subtotal gastrectomy, including the duodenal bulb. SRCC of the duodenal bulb was diagnosed based on pathology after surgery. Post-operatively, the patient experienced persistent gastrointestinal bleeding. Family declined further intervention and the patient eventually died one month post-resection.

Conclusions

SRCC in the duodenal bulb is difficult to diagnose. For those with high-risk factors, endoscopic examination and biopsy are recommended. For patients who can receive radical tumor resection, pancreaticoduodenectomy (PD) is considered a first-line option. Early diagnosis and resection have been shown to improve prognosis.

Duodenal adenocarcinoma with skin metastasis as initial manifestation: A case report

Background

Duodenal adenocarcinoma (DA) with skin metastasis as initial manifestation is clinically rare. In this study, we report a rare case of skin metastasis of DA.

Case presentation

An 84-year-old male patient developed multiple ecchymoses on the trunk and lower extremities. Physical examination showed that the ecchymosis was dark red and had a hard texture, but showed no bulging, rupture, or tenderness. The skin biopsy implied skin metastatic adenocarcinoma. After an endoscopic duodenal biopsy, the patient was finally diagnosed with DA with skin metastasis. The patient received two courses of oral treatment of Tegafur (40 mg, bid d1–d14). However, the patient stopped taking Tegafur because of its poor effect and received Chinese medicine as a replacement treatment. Unfortunately, he was lost to follow-up.

Conclusions

Early diagnosis of DA metastasis is of significant importance as prognosis of these patients is poor.

Laparoscopic segmental resection for tumours of the Angle of Treitz: a challenging but feasible surgical option. Results from a retrospective case-series analysis

Tumours of the small intestine are rare and account for about 5% of gastrointestinal tract neoplasms. The angle of Treitz (AT) could be defined as the intestinal loop comprised between the third duodenal portion and the first 10 cm of jejunum. A gold standard surgical treatment for AT neoplasm has not yet been well defined. This paper is focused on a very rare disease and at the best of our knowledge this is the largest case series in the literature about the Laparoscopic Segmental Resection (LSR) of AT tumours. Using a prospectively collected database, all data of consecutive patients, from January 2007 to May 2019, who underwent LSR for AT tumours at two different institutions were analysed. Patients’ demographics, intra and post-operative data, 30-day mortality and overall survival were collected. A total of 16 patients were retrieved from our database. The mean operative time was 206,5 ± 79 min. Conversion to open surgery was needed in two cases due to tumor size and, respectively, invasion of the transverse colon which required a multivisceral resection. The mean distal and proximal resection margins were 7.4 ± 2.2 and 3.9 ± 1.2 cm. The median number of harvested nodes was 9 ± 3. Pathological diagnosis was GIST in 11 cases, adenocarcinoma in 4 and sarcoma in 1 case. In conclusion, in experienced hands, LSR appears to be a safe and effective treatment option for tumours of the AT. Prospective studies are needed to confirm these findings.

Duodenal adenocarcinoma: Surgical results of 27 patients treated at a single center

INTRODUCTION

Duodenal adenocarcinoma is a rare malignancy. Given the rarity of the disease, there is limited data related to resection results. The objective is to analyze results at our hospital after the curative resection of duodenal adenocarcinoma (DA).

METHODS

The variables were retrospectively collected from patients operated on between 1990 and 2017 at our hospital.

RESULTS

A total of 27 patients were treated. Twenty-three patients (85%) underwent pancreaticoduodenectomy, and 4 patients (15%) with tumors located in the third and fourth portions of the duodenum underwent segmental duodenal resection. The overall postoperative morbidity was 67% (18 patients). Postoperative mortality was 7% (2 patients); however, postoperative mortality related to surgery was 4% (1 patient). All patients had negative resection margins. A median of 18 lymph nodes (range, 0-38) were retrieved and evaluated, with a median of 1 involved node (range, 0-8). Median follow up was 23 (9-69.7) months. Actuarial overall survival was 62.2 (25.2-99.1) months. Actuarial disease-free survival was 49 (0-133) months.

CONCLUSIONS

The surgical treatment of duodenal adenocarcinoma is associated with a high morbidity, although it achieves considerable survival. Depending on the tumor location and if there is no pancreatic infiltration, segmental duodenal resection with negative margins is an alternative to cephalic pancreaticoduodenectomy.

Focus on the diagnostic problems of primary adenocarcinoma of the third and fourth portion of the duodenum. Case report

Although the small intestine constitutes over 75% of the length and 90% of the mucosal surface of the gastrointestinal tract, small intestine cancer is rare and accounts for only 1% of gastrointestinal malignancies. Adenocarcinoma together with carcinoid tumours are the most common histological types of primary malignant tumours of the small bowel but others, including lymphoma and leiomyosarcoma, may less frequently be encountered. Adenocarcinomas are predominantly located in the duodenum. Primary adenocarcinoma of the duodenum is a rare malignant tumor, accounting for 0.3-0.5% of all gastroenteral malignancies. The diagnosis of primary adenocarcinoma of duodenum is often delayed because its symptoms and signs are nonspecific. In this work we want to focus on the diagnostic and therapeutic problems of duodenal adenocarcinoma, reporting a case report.

[Moderately differentiated adenocarcinoma of the third duodenal portion]

BACKGROUND

Duodenal carcinoma is very rare. It represents 33-45% of the all tumours of the small bowel. The symptoms are non-specific, and the diagnosis is often accidental.

CLINICAL CASE

A 35-year old man was admitted to our hospital with post-prandial abdominal pain. Upper gastrointestinal examination revealed a tumour of the third duodenal portion, which was diagnosed, using endoscopic biopsy, as a tubular adenoma with high grade dysplasia. The computed axial tomography scan, the magnetic resonance imaging, and the endoscopic ultrasound showed the neoplasia of the third duodenal portion with no lymph node or peritoneal metastases. Partial resection of the duodenum was performed. The definitive histopathological diagnosis was primary adenocarcinoma of the third duodenal portion. pT2 N0M0, originated in a tubular adenoma.

CONCLUSIONS

Primitive neoplasia of the duodenum is very rare. Duodeno-cephalo-pancreatectomy is recommended in proximally located tumours, while segmental resection of the duodenum is appropriate for distal locations, with the same survival.

Segmental duodenal resection: indications, surgical techniques and postoperative outcomes

INTRODUCTION

Segmental duodenal resections (DR) have been increasingly performed for the treatment of primary duodenal tumours. The aim of the study is to review the indications for, clinical and operative details, and outcomes of patients undergoing elective DR.

MATERIAL AND METHODS

We retrospectively reviewed all patients who underwent elective segmental DR for the treatment of primary duodenal tumours, at a single institution between January 2007 and December 2013. Demographic data, clinical presentation, preoperative investigations, operative details, postoperative complications/mortality and histopathological results were recorded.

RESULTS

In the study period, 11 duodenal resections were performed (7 male, median age 61 years). Thirty-six percent of the patients presented with anaemia. Surgical resection included two or more segments in seven patients. The most frequently resected part of the duodenum was segment 3 (n = 7). Median operative time was 191 min and blood loss was 675 ml. End-to-end and end-to-side anastomoses were performed in equal numbers. The pathology of resected specimens included adenocarcinoma (n = 4), gastrointestinal stromal tumour (GIST) (n = 1), adenoma (n = 5) and lymphoma (n = 1). Median hospital stay was 14 days. Overall, 30-day morbidity rate was 82% (78% Clavien 2 or less).

CONCLUSIONS

Segmental duodenal resection is a safe and effective surgical technique for the resection of primary duodenal tumours.

Primary Duodenal Adenocarcinoma without Stenosis: A Case Report with a Brief Literature Review

This article focuses on the symptomatic and diagnostic problems of primary duodenal adenocarcinoma (PDA) by way of two case reports and a literature review. An 85-year-old woman with an adenocarcinoma in the 1st duodenal portion was offered palliative care. A 90-year-old woman with an adenocarcinoma in the 3rd duodenal portion was also offered palliative care. A unique finding in the two cases reported herein is that PDA did not cause stenosis and occlusion of the lumen. As no reports of PDA without stenosis have been published so far, these cases may add to our knowledge of PDA. The diagnosis of PDA is often delayed because its symptoms may be absent until the tumor has progressed, thus leading to a delay of several months. Patients typically present with a long history of variable and vague symptoms, and many are diagnosed with advanced disease. As regards clinical manifestations, abdominal pain is the most frequent symptom. The majority of these tumors are found to have infiltrated the duodenal wall at presentation, with many being unresectable due to local and distal invasion. Esophagogastroduodenoscopy and gastrointestinal barium radiography are the main diagnostic tests for PDA, detecting 88.6 and 83.3% of tumors, respectively. In some cases, ultrasonography or computed tomography are useful for detecting PDA and determining vascular invasion.

Primary adenocarcinoma of the fourth portion of the duodenum: "A case report and literature review"

INTRODUCTION

Primary adenocarcinoma of the 4th portion of the duodenum is reported less frequently than those other portions of the duodenum. Therefore, few reports discuss the diagnosis and treatment of this malignancy.

PRESENTATION OF CASE

A 54-year-old woman was admitted to our hospital with a complaint of nausea and vomiting after a meal. Upper gastrointestinal examination and a duodenogram revealed a Type 2 tumor of the 4th portion of the duodenum, which was diagnosed as well-differentiated tubular adenocarcinoma by endoscopic biopsy. Partial resection of the duodenum and jejunum was performed on the basis of intraoperative evaluation of negative lymph node metastasis around the pancreas and proximal duodenum with no macroscopic invasion toward the pancreas and proximal duodenal margin. Her postoperative course was uneventful without any sign of recurrence 5 years later.

DISCUSSION

Primary adenocarcinoma in the 4th portion is relatively less common. It is not easy to diagnose this disease. Patients with primary duodenal adenocaricinoma, who are medically fit to undergo surgery, should be given the option of aggressive resection. Duodeno-cephalo-pancreatectomy remains the standard treatment for adenocarcinomas of the 1st and 2nd portion of the duodenum. Partial resection is the preferred surgical method for patients with adenocarcinoma of the 3rd and 4th portions of the duodenum.

CONCLUSION

This report describes a rare case of primary adenocarcinoma of the 4th portion of the duodenum, successfully treated by partial resection of the duodenum and jejunum. However, larger studies are required to clarify the indications for the preferred surgical method for this malignancy.

Recurrent Adenocarcinoma of Colon Presenting as Duodenal Metastasis With Partial Gastric Outlet Obstruction: A Case Report With Review of Literature

Colorectal cancer is one of the leading causes of cancer related deaths in western world. While most common site for metastasis for colon cancer is liver, lung, and the peritoneum, metastasis to various other organs such as brain, bones and thyroid has been reported. Metastatic lesions to the small bowel are more common than primary lesions and most common primary neoplasms that metastasize to the duodenum are lung cancer, renal cell carcinoma, breast cancer, and malignant melanoma. We report a very rare case of recurrent adenocarcinoma of colon metastasizing to duodenum after 2 years of curative resection of primary cancer. Surgical resection for curative intent as well as palliative management is recommended.
