Pancreaticoduodenectomy for hepatic portal lymph node metastasis after hepatic resection for hepatocellular carcinoma: A clinical case report.

Int J Surg Case Rep 2021 May 27;82:105921. Epub 2021 Apr 27.

Center for Pathology and Cytology, Bach Mai Hospital, Viet Nam.

Introduction: In 2018, Hepatocellular carcinoma (HCC) was predicted to be the sixth most commonly diagnosed cancer. Extra-hepatic metastasis due to HCC is a poor prognostic factor, depending on the stage of the disease.

Presentation Of Case: We report a case of a 52-years old male who had undergone Segment 5 (S5) hepatectomy for HCC of 4.7 × 2 cm. Transcatheter arterial chemoembolization (TACE) four times postoperatively was performed based on a preoperative diagnosis of a recurrent tumour at the S1. After 2 years, the solitary tumour (7.5 × 2.5 × 3.5 cm) is located behind the right lobe of the liver and the head of the pancreas. The tumour was abnormally supplied with blood from the superior mesenteric artery (SMA) and the gastroduodenal artery (GDA). The patient was underwent pancreaticoduodenectomy (PD) to remove a large tumour. Postoperative pathology and immunohistochemical staining showed metastatic HCC. There was no tumour recurrence after 6 months.

Discussion: The organs in the body that liver cancer cells most often spread to are the lungs (44%), the portal vein (35%), the hepatobiliary ganglion (27%), and a small number of cases of bone, eye socket, bronchus metastases. Otherwise, recurrence of lymph nodes (LNs) after hepatectomy for HCC is very rare.

Conclusions: HCC can metastasize to the hepatic pedicle LN after hepatectomy and maybe confused with recurrent liver tumours in the S1. Indications for PD are feasible for solitary metastatic at peri-pancreas. Pathology incorporating immunohistochemistry can determine the origin of metastases.

Causes and Clinical Characteristics of Small Bowel Bleeding in Northern Vietnam.

Can J Gastroenterol Hepatol 2020 27;2020:8884092. Epub 2020 Nov 27.

Department of Gastroenterology & Hepatology, Bach Mai Hospital, Hanoi, Vietnam.

Aim: Causes, clinical features, and diagnostic approaches for small bowel (SB) bleeding were analyzed to derive recommendations in dealing with this clinical condition.

Methods: We included 54 patients undergoing surgical treatment for SB bleeding, from January 2009 to December 2019. Detailed clinical data, diagnosis procedures, and causes of bleeding were collected.

Results: Among 54 cases with SB bleeding, the most common causes were tumors (64.8%), followed by angiopathy (14.8%), ulcers (9.3%), diverticula (5.6%), tuberculosis (3.7%), and enteritis (1.9%). Most tumors (32/35 cases, 91.4%) and vascular lesions (8/8 cases, 100%) were located in the jejunum. The incidence of tumors was higher in the older (30/41 cases, 73.1%) than that in patients younger than 40 years of age (5/13 cases, 38.5%, < 0.01). Common initial findings were melena (68.5%) and hematochezia (31.5%). The overall diagnostic yield of computed tomographic enterography (CTE) was 57.4% (31/54 cases), with the figures for tumors, vascular lesions, and inflammatory lesions being 71.4% (25/35 cases), 62.5% (5/8 cases), and 12.5% (1/8 cases), respectively. Double-balloon enteroscopy (DBE) definitively identified SB bleeding sources in 16/22 (72.7%) patients.

Conclusion: Tumors, angiopathy, ulcers, and diverticula were the most common causes of SB bleeding in Northern Vietnamese population. CTE has a high detection rate for tumors in patients with SB bleeding. CTE as a triage tool may identify patients before double-balloon enteroscopy because of the high prevalence of SB tumors.

Application of the Bethesda System for Reporting Thyroid Cytopathology in the Pediatric Population.

Am J Clin Pathol 2021 04;155(5):680-689

Department of Pathology, Kameda Medical Center, Kamogawa, Japan.

Objectives: We aimed to provide the Asian experience with the Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) in pediatric thyroid nodules.

Methods: Consecutive thyroid fine-needle aspirates (patient age, ≤18 years) were retrospectively collected from 7 tertiary centers in 5 Asian countries.

Results: Of 194,364 thyroid aspirates, 0.6% were pediatric cases (mean age, 15.0 years). Among 827 nodules with accessible follow-up, the resection rate and risk of malignancy (ROM) were 36.3% and 59.0%, respectively. Malignant nodules (n = 179) accounted for 59.7% of resected nodules and 21.6% of all thyroid nodules with available follow-up. Compared with the published adult series, pediatric nodules had a higher resection rate and ROM, particularly in the indeterminate categories.

Conclusions: Our study demonstrates that Asian pediatric thyroid nodules had higher ROM than those from adults. The prototypic outputs of TBSRTC may need to be adjusted in the pediatric population.
