Current Status of Bariatric and Metabolic Surgery in Daejeon and Chungcheong Province: Early Experiences after Public Medical Insurance Coverage in 2019.

Purpose: This study aimed to investigate the current status of bariatric and metabolic surgery in Daejeon and Chungcheong province and to describe the early experiences after public medical insurance coverage in 2019.

Materials And Methods: Between January 2019 and August 2019, 64 cases of bariatric and metabolic surgery were performed in patients with morbid obesity or uncontrolled type 2 diabetes. We prospectively collected and analyzed data regarding the patients' demographics and comorbidities, surgical results, and early complications.

Fetal growth of the anal sinus and sphincters, especially in relation to anal anomalies.

Purpose And Methods: The anal sinuses, small furrows above the pectinate line, sometimes form perianal abscesses in adults. We examined the pattern of fetal growth of the anal sinus and sphincters using 22 mid-term (8-18 weeks) and 6 late-stage (30-38 weeks) fetuses.

Results: In mid-term fetuses, the external and internal sphincters gradually increased in thickness, depending on specimen size (from 0.

Clinical feasibility and nutritional effects of early oral feeding after pancreaticoduodenectomy.

Backgrounds/aims: Pancreaticoduodenctomy (PD) is associated with high rates of postoperative morbidity and mortality. Although many studies have shown that early postoperative enteral nutrition improves postoperative outcomes, limited clinical information is available on postoperative early oral feeding (EOF) after PD. The aim of this study was to evaluate the clinical feasibility, safety, and nutritional effects of EOF after PD.

Usefulness of artificial jump graft to portal vein thrombosis in deceased donor liver transplantation.

Severe portal vein thrombosis (PVT) is often considered a relative contraindication for living donor liver transplantation due to high associated risks and morbidity. Meanwhile, improvement in operative techniques, resulting in higher success rates has removed PVT from the list of contraindications in deceased donor liver transplantation (DDLT). In this report, we describe a surgical technique for DDLT using polytetrafluoroethylene graft from the inferior mesenteric vein for portal inflow in patient with portomesenteric thrombosis.

Upper terminal of the inferior vena cava and development of the heart atriums: a study using human embryos.

In the embryonic heart, the primitive atrium is considered to receive the bilateral sinus horns including the upper terminal of the inferior vena cava (IVC). To reveal topographical anatomy of the embryonic venous pole of the heart, we examined horizontal serial paraffin sections of 15 human embryos with crown-rump length 9-31 mm, corresponding to a gestational age of 6-7 weeks or Carnegie stage 14-16. The IVC was often fixed to the developing right pulmonary vein by a mesentery-like fibrous tissue.

Mesoesophagus and other fascial structures of the abdominal and lower thoracic esophagus: a histological study using human embryos and fetuses.

A term "mesoesophagus" has been often used by surgeons, but the morphology was not described well. To better understand the structures attaching the human abdominal and lower thoracic esophagus to the body wall, we examined serial or semiserial sections from 10 embryos and 9 fetuses. The esophagus was initially embedded in a large posterior mesenchymal tissue, which included the vertebral column and aorta.

Liver agenesis with omphalocele: a report of two human embryos using serial histological sections.

We identified 2 human embryos, with crown-rump lengths (CRLs) of 22 mm and 23 mm and a gestational age of approximately 7 weeks (O'Rahilly's stage 21-22), with liver agenesis and omphalocele. Serial histological sections were prepared of the entire body of one specimen, whereas sections of the neck, including the upper part of the heart, were missed for the other specimen as a result of tissue damage during the abortion. In addition, isolated omphalocele was assessed in another embryo (CRL  =  25 mm) for comparison with atypical omphalocele in the embryos with liver agenesis.

Denonvilliers' fascia revisited.

Although several studies have reported that the peritoneum does not contribute to the formation of a fascia between the urogenital organs and rectum, Denonvilliers' fascia (DF), a fascia between the mesorectum and prostate (or vagina) in adults, is believed to be a remnant of the peritoneum. Remnants of the peritoneum, however, were reportedly difficult to detect in other fusion fasciae of the abdominopelvic region in mid-term fetuses. To examine morphological changes of the pelvic cul-de-sac of the peritoneum, we examined 18 male and 6 female embryos and fetuses.

Lymphocyte subpopulations in the liver, spleen, intestines, and mesenteric nodes: an immunohistochemical study using human fetuses at 15-16 weeks.

The roles of the liver and intestines in lymphocyte differentiation in human fetuses were assessed by immunohistochemical analysis of the thymus, bone marrow, liver, spleen, intestines, and lymph nodes of 15-16 week human fetuses using primary antibodies against IgM, CD3, CD7, CD8, CD10, CD20, CD45RO, HLA-DR, and CD68. The density of immunoreactive lymphocytes was high in the thymus and lymph nodes, but much lower in the bones, liver, spleen, and intestines. The medulla of the thymus contained IgM-positive mature B lymphocytes as well as CD20-positve B lymphocytes.

Region-specific differences in the human myenteric plexus: an immunohistochemical study using donated elderly cadavers.

Purpose And Methods: To identify site-dependent and individual differences in neuronal nitric oxide synthase (nNOS)-positive nerves of the myenteric plexus, we examined full-thickness walls of the stomach, pylorus, duodenum, ileum, colon, and rectum in 7 male and 8 female cadavers (mean ages, 80 and 87 years, respectively).

Results: The areas occupied by nNOS-positive nerve fibers in the myenteric plexus were fragmentary and overlapped with areas occupied by vasoactive intestinal polypeptide-positive fibers. The nNOS-positive fiber-containing areas per 1-mm length of intermuscular space tended to be larger at more anal sites, with positive areas four times greater in the rectum than in the stomach.

Distribution of CD10-positive epithelial and mesenchymal cells in human mid-term fetuses: a comparison with CD34 expression.

CD10, a marker of immature B lymphocytes, is expressed in the developing epithelium of mammary glands, hair follicles, and renal tubules of human fetuses. To assess mesenchymal and stromal expression of CD10, we performed immunohistochemical assays in whole body sections from eight fetuses of gestational ages 15-20 weeks. In addition to expression in urinary tract and intestinal epithelium, CD10 was strongly expressed at both gestational ages in fibrous tissues surrounding the airways from the larynx to lung alveoli, in the periosteum and ossification center, and in the glans of external genitalia.

Clinicopathological characteristics and prognostic factors in combined hepatocellular carcinoma and cholangiocarcinoma.

Backgrounds/aims: Combined hepatocellular carcinoma and cholangiocarcinoma (cHCC-CC) is an uncommon subtype of primary liver cancer that has rarely been reported in detail. This study was performed in order to evaluate the clinicopathological characteristics and prognostic factors of cHCC-CC in single center.

Methods: The clinicopathological features of patients diagnosed and operated with cHCC-CC at Chonbuk National Hospital between July 1998 and July 2007 were retrospectively studied by comparing them with patients with only hepatocellular carcinoma (HCC) who had undergone a hepatic resection during the same period.

Computer-assisted three-dimensional reconstruction of the fetal pancreas including the supplying arteries according to immunohistochemistry of pancreatic polypeptide.

Purpose: Computer-assisted three-dimensional reconstruction of the fetal human pancreas was prepared to reconsider topographical relation between the dorsal/ventral anlagen and the vascular supply.

Methods: Tissue sections from the upper abdominal viscera of three fetuses were examined. Sections were immunohistochemically stained to determine pancreatic polypeptide expression, a marker of the ventral pancreas.

Topographical anatomy of Spiegel's lobe and its adjacent organs in mid-term fetuses: Its implication on the development of the lesser sac and adult morphology of the upper abdomen.

At 8-16 weeks of gestation, Spiegel's lobe of the caudate lobe appears as a sac-like herniation of the liver parenchyma between the inferior vena cava and ductus venosus or Arantius' duct. In 5 of 11 fetuses at 20-30 weeks of gestation, we found that an external notch was formed into the posterior aspect of the caudate lobe by a peritoneal fold containing the left gastric artery. This notch appeared to correspond to that observed in adults, which is usually seen at the antero-inferior margin of the lobe after rotation of the lobe along the horizontal or transverse axis.

Prognostic factors for survival in patients with hepatic recurrence after curative resection of gastric cancer.

Background: This study was done to evaluate the prognostic factors that may affect the survival of patients with recurrent hepatic metastasis after curative resection of gastric cancer.

Methods: We reviewed the medical records of 73 patients with recurrent hepatic metastasis after surgical treatment of gastric cancer from January 1995 to December 2005. Prognostic factors were classified into three groups: primary tumor factors, recurrent hepatic factors, and treatment factors.

Serum response factor enhances liver metastasis of colorectal carcinoma via alteration of the E-cadherin/beta-catenin complex.

Serum response factor (SRF) is a transcription factor that controls cell growth, differentiation, and tumor progression as well as muscle development and function. Reduced expression of cell adhesion molecules has been reported to be associated with tumor metastasis. The aim of this study was to evaluate the expression and a role of SRF in liver metastasis of primary colorectal carcinomas.
