Risk factors for preoperative carcinogenesis of bile duct cysts in adults.

Background: Bile duct cyst (BDC) is a rare congenital bile duct malformation. The incidence of bile duct malignancy in BDC patients is markedly higher than that in the general population. However, few studies have been conducted on the risk factors for preoperative carcinogenesis in BDC patients.

Development, validation and comparison of four methods for quantifying endogenous 25OH-D3 in human plasma.

To meet the increasing clinical needs for 25-hydroxyvitamin D3 (25OH-D3) detection, the development of an efficient and accurate high-performance liquid chromatography-mass spectrometry (HPLC-MS) method for plasma 25OH-D3 quantitation is important. Since 25OH-D3 is an endogenous compound, the lack of a plasma blank increases the difficulty of accurately quantifying 25OH-D3. Selection of a method suitable for clinical monitoring among various methods for endogenous compound quantification is necessary.

Schwannoma originating from the recurrent laryngeal nerve in a thyroid cancer patient: A case report and review of the literature.

Background: Schwannoma rarely originates from the recurrent laryngeal nerve, and there are few reports on schwannoma originating from the recurrent nerve in the mediastinum. Herein, we present an extremely rare case of schwannoma originating from the recurrent laryngeal nerve in the neck.

Case Summary: This is a case report of one patient diagnosed with thyroid cancer with schwannoma originating from the recurrent laryngeal nerve in the neck, which was incidentally found during a thyroidectomy, and a review of the literature.

[Diagnosis and Treatment of Epithelioid Hemangioendothelioma].

Objective To evaluate the clinical feature,diagnosis,and treatment of epithelioid hemangioendothelioma(EHE).Methods Data of 30 EHE patients admitted from January 2001 to December 2017 were retrospectively analyzed. The auxiliary examinations,treatment method,pathological findings,and prognoses were analyzed.

Risk Factors for Nodal Metastasis in cN0 Papillary Thyroid Microcarcinoma.

Background: Despite the majority of papillary thyroid microcarcinoma (PTMC) patients having an excellent prognosis, cervical lymph node metastases are common. The purpose of this study was to investigate the incidence and the predictive risk factors for occult central compartment lymph node metastasis (CLNM) in PTMC patients.

Materials And Methods: 178 patients with clinically node-negative (cN0) PTMC undergoing prophylactic central compartment neck dissection in our hospital from January 2008 to Jun 2010 were enrolled.

Choledochoduodenal fistula caused by migration of endoclip after laparoscopic cholecystectomy.

The wide use of surgical endoclips in laparoscopic surgery has led to a variety of complications. Post-cholecystectomy endoclips migrating into the common bile duct after laparoscopic cholecystectomy is rare. A migrated endoclip can cause obstruction, serve as a nidus for stone formation, and cause cholangitis.

Ileal duplication mimicking intestinal intussusception: a congenital condition rarely reported in adult.

Intestinal duplication is an uncommon congenital condition in young adults. A 25-year-old man complained of chronic, intermittent abdominal pain for 3 years following previous appendectomy for the treatment of suspected appendicitis. Abdominal discomfort and pain, suggestive of intestinal obstruction, recurred after operation.

Mirizzi syndrome: our experience with 27 cases in PUMC Hospital.

Objective: To retrospectively evaluate the diagnosis and treatment of Mirizzi syndrome (MS).

Methods: Patients who received elective or emergency cholecystectomies in our center during 23 years were retrospectively evaluated. The data reviewed included demography, clinical presentations, diagnostic methods, surgical procedures, postoperative complications, and follow-up.

A long adult intussusception secondary to transverse colon cancer.

The occurrence of adult intussusception arising from colorectal cancer is quite rare. We present the case of a 76-year-old man with sudden abdominal pain and vomiting. Clinical symptoms included severe abdominal distension and tenderness.
