Prevalence of Malnutrition in Hospitalized Patients: a Multicenter Cross-sectional Study

BACKGROUND: Malnutrition is associated with many adverse clinical outcomes. The present study aimed to identify the prevalence of malnutrition in hospitalized patients in Korea, evaluate the association between malnutrition and clinical outcomes, and ascertain the risk factors of malnutrition. METHODS: A multicenter cross-sectional study was performed with 300 patients recruited from among the patients admitted in 25 hospitals on January 6, 2014. Nutritional status was assessed by using the Subjective Global Assessment (SGA). Demographic characteristics and underlying diseases were compared according to nutritional status. Logistic regression analysis was performed to identify the risk factors of malnutrition. Clinical outcomes such as rate of admission in intensive care units, length of hospital stay, and survival rate were evaluated. RESULTS: The prevalence of malnutrition in the hospitalized patients was 22.0%. Old age (≥ 70 years), admission for medical treatment or diagnostic work-up, and underlying pulmonary or oncological disease were associated with malnutrition. Old age and admission for medical treatment or diagnostic work-up were identified to be risk factors of malnutrition in the multivariate analysis. Patients with malnutrition had longer hospital stay (SGA A = 7.63 ± 6.03 days, B = 9.02 ± 9.96 days, and C = 12.18 ± 7.24 days, P = 0.018) and lower 90-day survival rate (SGA A = 97.9%, B = 90.7%, and C = 58.3%, P < 0.001). CONCLUSION: Malnutrition was common in hospitalized patients, and resulted in longer hospitalization and associated lower survival rate. The rate of malnutrition tended to be higher when the patient was older than 70 years old or hospitalized for medical treatment or diagnostic work-up compared to elective surgery.

Relationship between Triglyceride and Bone Mineral Density in Healthy Korean Men

BACKGROUND: As the elderly population increasing, the interest in osteoporosis, hyperlipidemia, and cardiovascular diseases has increased in recent years. In accordance with such trend, many studies regarding correlations between bone density and hyperlipidemia have been conducted. However, the study outcomes have been inconsistent so far, and most of the studies focused on females. Therefore, this study aimed to investigate the correlation between serum lipid levels and bone density in healthy Korean male adults. METHODS: This study surveyed 851 male adults, who visited an examination center at a university hospital, on smoking, drinking, hypertension, and diabetes history. A laboratory examination measured total cholesterol, triglyceride, low density lipoprotein cholesterol, high density lipoprotein cholesterol, apolipoprotein A-1, and apolipoprotein B. For bone density, lumbar, femoral neck, and femur were measured using dual energy X-ray absorptiometry. RESULTS: Body mass index (BMI) and bone density T-value showed a positive correlation. Triglyceride exhibited a positive correlation with bone density T-value, and they still revealed a significant positive correlation after correcting for age and BMI. While high density lipoprotein cholesterol showed a negative correlation with bone density, they were not correlated significantly after correcting for age and BMI. There was no correlation found between low density lipoprotein cholesterol and bone density. CONCLUSIONS: This study confirmed that bone densities of all areas measured were significantly increased in Korean male adults as triglyceride increased. Total cholesterol, high density lipoprotein cholesterol, and low density lipoprotein cholesterol did not show a significant correlation with bone density.

Laparoscopic Primary Closure: A Better Method of Treatment in Perforated Peptic Ulcer Disease than Open Repair

PURPOSE: Perforation is a dreadful complication of peptic ulcer disease requiring immediate management. This study examined the feasibility of laparoscopic primary closure in perforated peptic ulcer disease to allow an earlier return to normal life. METHODS: This study reviewed our experience retrospectively with 72 consecutive patients treated with the simple closure of a perforated peptic ulcer disease in our hospital from December 2002 to January 2011. Thirty five patients were treated laparoscopically and the rest underwent open surgery. The operative time, nasogastric tube utilization, abdominal drain usage, time to oral feeding, hospital stay, postoperative complications and recurrence in both groups were compared. A student's t-test was used to make the comparisons. A p value<0.05 was considered significant. RESULTS: The operative time, use of nasogastric tubes, and abdominal drainage were similar in both groups. After laparoscopic surgery, the patients showed an earlier return to normal oral feeding and discharge than the open surgery group (4.17+/-0.62 vs. 5.03+/-2.34 days, p=0.040, 8.63+/-1.96 vs. 10.24+/-3.59 days, p=0.021, respectively). The decreased handling of tissue in laparoscopic surgery led to less wound infection (0 in laparoscopic surgery vs. 3 in open) and postoperative ileus (0 vs. 2). CONCLUSION: Laparoscopic repair of a perforated peptic ulcer is a safe and feasible treatment that offers early oral feeding and a shorter postoperative hospital stay.

Clinical Significance of Lymph Node Ratio in Stage III Colorectal Cancer

PURPOSE: Recent literature has shown that lymph node ratio is superior to the absolute number of metastatic lymph nodes in predicting the prognosis in several malignances other than colorectal cancer. The aim of this study was to evaluate the prognostic significance of the lymph node ratio (LNR) in patients with stage III colorectal cancer. METHODS: We included 186 stage III colorectal cancer patients who underwent a curative resection over a 10-year period in one hospital. The cutoff point of LNR was chosen as 0.07 because there was significant survival difference at that LNR. The Kaplan-Meier and the Cox proportional hazard models were used to evaluate the prognostic effect according to LNR. RESULTS: There was statistically significant longer overall survival in the group of LNR > 0.07 than in the group of LNR 0.07, P = 0.025), but there was no survival difference for the N2 group (4 > or = LN) according to LNR. The multivariate analysis showed that the LNR is an independent prognostic factor. CONCLUSIONS: LNR can be considered as a more accurate and potent modality for prognostic stratifications in patients with stage III colorectal cancer.

Is Conservative Treatment with Antibiotics the Correct Strategy for Management of Right Colonic Diverticulitis?: A Prospective Study

PURPOSE: The goals of this study were to identify whether conservative treatment with antibiotics in right colonic diverticulitis (RCD) patients, our empirical method used until now, is adequate and to determine how the natural history of RCD is affected by conservative treatment. METHODS: This study was designed as a case-control study. Group I was comprised of 12 patients who were managed conservatively, and clinical data were retrospectively collected. In group II, a total of 49 patients, diagnosed by using diagnostic criteria for RCD and managed conservatively, were prospectively included. RESULTS: The period of fasting was 2.7 days, and the hospital stay was 4.6 days in all patients. The intravenous and the oral antibiotic periods were 3.8 days and 9.8 days, respectively. There were no statistically significant differences in treatment results between the two groups except the duration of fasting and the hospitalization, and there were no complications under conservative treatment. Eight patients (13.1%) had recurrent diverticulitis during the follow-up period. The recurrence risk showed no significant difference between the groups. The RCD-free period after management was 60.1 months, and patients with recurrent RCD were treated by conservative treatment or laparoscopic surgery. CONCLUSION: Conservative treatment with antibiotics is the optimal treatment of choice for RCD and shows no increase in complications.

Analysis of Prognosis in Colorectal Mucinous Adenocarcinoma: A Retrospective Analysis with Peritoneal Fluid

PURPOSE: Although many papers have reported poor prognosis of colorectal mucinous adenocarcinoma, the underlying cause for its unfavorable outcome is yet to be elucidated. In the peritoneal fluid studies, we observed that peritoneal recurrences and cytology positive cases were many times mucinous cancers. On the basis of these observations, mucinous and non-mucinous adenocarcinomas were compared and prognostic factors were studied. METHODS: Five hundred and forty-six patients who underwent surgery for colorectal adenocarcinomas from January 2004 to December 2008 were included. RESULTS: Among the 546 patients, mucinous adenocarcinomas were 30 (5.5%) and non-mucinous adenocarcinomas were 516 (94.5%). Mean age was 55.0 years, which was younger than 63.2 years in non-mucinous colon cancers. They tend to develop in the right colon. Mucinous adenocarcinomas were more advanced in depth of invasion and distant metastasis, but no significant difference in lymph node (LN) metastasis. Peritoneal CEA, CA19-9, and positive cytology were more apparent. Liver and peritoneal metastasis did not show significant increases. Five year survival rates were 82.9% and 91.7% and cancer free survival rates were 42.7% and 68.5% each, respectively, for mucinous and non-mucinous cancers. According to stage, only stage III and IV patients showed differences in cancer free survival and overall survival (P=0.001, 0.040). CONCLUSION: Mucinous adenocarcinomas showed worse prognoses and significant differences in recurrences, but had similar prognoses in early cancers. Although no significant differences were in LN metastasis, dissimilarities were in infiltration depth. Infiltrations led to the increase in free cancer cells and peritoneal fluid tumor markers: ultimately cancer recurrences developed.

Early Experience of Treatment for Symptomatic Hemorrhoids with Doppler Guided Hemorrhoidal Artery Ligation and Recto-anal Repair

PURPOSE: Despite all developments in recent years, the choice of an adequate treatment for hemorrhoids remains a problem. Hemorrhoidal artery ligation and recto-anal repair (HAL-RAR) is a nonexcisional surgical technique for the treatment of hemorrhoids, consisting in the ligation of the distal branches of the superior rectal artery, resulting in a reduction of blood flow and decongestion of the hemorrhoidal plexus. The aim of this study was to present the early experience of treating hemorrhoids with HAL-RAR. METHODS: Between December 2008 and November 2009, 70 consecutive patients with symptomatic hemorrhoids were treated with HAL-RAR. The patients underwent sonographic identification and suture ligation of 4 to 8 terminal branches of the superior rectal artery above the dentate line. RESULTS: There were 33 males and 37 females (mean age, 49.72+/-14.1 years). The mean operative time was 43.8 minutes (25~80 min). Most patients (=61, 87%) were without any complaint upon follow-up at 1 week. Nine patients presented with early complication: isolated pain in 1, anemia in 1, isolated bleeding in 1, voiding difficulty (over 1 day) in 2 and tenesmus (over 2 weeks) in 4. CONCLUSION: Based on our results we may conclude that HAL-RAR is a minimally invasive, safe and effective method and may offer an important alternative for the treatment of hemorrhoids. It may offer minimally postoperative pain, and early return of patients to their normal activities.

A Case of Adult Intussusception Induced by Intestinal Tuberculosis / 결핵및호흡기질환

Intussusception primarily occurs in children and is uncommon in adults. Moreover, intussusception caused by intestinal tuberculosis is very rare. We report a case of intussusception induced by intestinal tuberculosis. A 53-year-old man presented to our hospital with complaints of cough and sputum for 2 weeks. We started anti-tuberculosis medication as the patient's sputum acid-fast staining was positive. After 4 days of treatment, the patient developed abdominal cramping pain. Imaging studies showed ileo-ileal type intussusception. The patient underwent segmental resection of the small bowel and intestinal tuberculosis was confirmed on histological examination. He recovered after surgery and was discharged on anti-tuberculosis medication.

Short-Term Outcome of Curative One-Stage Laparoscopic Resection for Obstructive Left-Sided Colon Cancers Followed by Stent Insertion: Comparative Study with Non-Obstructive Left-Sided Colon Cancers

PURPOSE: Laparoscopic surgery has been considered to be contraindicated for treating malignant colorectal obstruction. Stent insertion for obstructive colorectal cancer has recently allowed laparoscopic surgery to be performed by means of preoperative bowel decompression and bowel preparation. The aim of this study is to evaluate the safety and the feasibility of a one-stage laparoscopic resection for obstructive left-sided colon cancer after stent insertion by comparing the results to those for non-obstructive left-sided colon cancer. METHODS: Between May 2006 and January 2009, a laparoscopic colorectal operation was performed on 18 consecutive patients with obstructive left-sided colon cancer after placement of a self-expandable stent by one colorectal surgeon, and the results were compared retrospectively to those for 43 patients with non-obstructive left-sided colon cancer who had undergone a laparoscopic procedure with the same surgeon. The collected data were the clinicopathologic characteristics, the perioperative complications, the oncologic outcomes, the postoperative recovery results, and the survival rate. RESULTS: The obstructive left-sided colon cancer group had significant benefits in retrieved lymph nodes (18.8+/-5.3 vs. 14.0+/-8.7, P=0.036), and distal resection margin (5.5+/-3.0 cm vs. 3.6+/-2.4 cm, P=0.011). There were no significant differences in other clinicopathological characteristics and oncologic outcomes, including the overall 3-yr survival rate, between the two groups. CONCLUSION: Preoperative stent decompression followed by a laparoscopic colorectal resection is a safe and feasible option for treating obstructive left-sided colon cancer. A further large-scale prospective study should be performed to evaluate the long-term outcome of a one-stage laparoscopic resection using stent insertion in cases of obstructive left-sided colon cancer.

Strangulated Small Bowel Herniation Through a 12-mm Trocar Site In an Obese Patient / 대한내시경복강경외과학회지

A trocar site hernia is a rare complication after laparoscopic surgery. Hence, a trocar site that's larger than 10 mm should be closed to prevent complications. Here we describe a case of strangulated small bowel herniation through a 12 mm-trocar site even though the fascia had been closed. A 78-year-old obese (BMI 30.7 kg/m2) patient with rectal cancer underwent an uncomplicated laparoscopic low anterior resection. On the eighth post-operative day, she presented with a right lower quadrant painful mass, and abdominal CT showed small bowel herniation through the right lower quadrant 12-mm trocar site. In the surgical field, the small bowel was resected via the extended trocar site wound and the fascial defect was repaired.

The Relatioships Between Tumor-related Gene Expression and Tumor Budding, Tumor Nodule and Lymph Node Extracapsular Extension in Colorectal Cancer

PURPOSE: Despite the similar lymph node metastasis observed in patients with advanced colorectal cancer (CRC), there was a different clinical outcome. The relationships between tumor-related gene expression and prognostic factors such as tumor budding, tumor nodule and extracapsular extension (ECE) of lymph nodes in patients with CRC remain unclear yet. The purpose of this study was to evaluate the relationship between expression of molecular markers such as vascular endothelial growth factor (VEGF), epidermal growth factor (EGF), matrix metalloproteinases (MMPs) and E-cadherin and the tumor budding, tumor nodule and ECE of lymph nodes in patients with stage III CRC. METHODS: The tissue of 87 patients with stage III CRC were investigated for expressions of molecular markers using immunohistochemical methods. RESULTS: VEGF and MMP-9 expression in tumor tissue were positively associated with the colorectal cancer prognostic factors such as tumor budding, tumor nodule and extracapsular lymph node extension (P<0.05). But, MMP-2, EGF and E-cadherin expression were of no value with regard to them. CONCLUSION: Our results suggest that molecular markers, in particular VEGF and MMP-9, may provide additional prognostic information regarding tumor budding, ECE and tumor nodule.

Multiple Primary Cancers Including Colorectal Cancer

PURPOSE: With advance in diagnostic techniques and treatment modalities, it has been increasing that the patients with colorectal cancer experience another primary malignancies. Understanding the characteristics of multiple primary malignancies is important to establish an effective surveillance program for the early detection of second cancer. METHODS: The database of 2,709 patients diagnosed with colorectal cancer between 1985 and 2007 in Kangnam St. Mary's Hospital was analyzed retrospectively. RESULTS: Out of 2,709 patients, 102 (3.76%) of them were found to have multiple malignancies. Among them, 37 patients had synchronous cancers and 65 patients had metachronous cancers. The most common site of multiple primary malignancies was the stomach, followed by kidney, thyroid and breast. CONCLUSIONS: In the patients with colorectal cancer, it should be considered to evaluate multiple primary malignancies, especially stomach, during the routine follow up. And the most frequent multiple primary cancer before colorectal cancer was also stomach cancer. Careful attention should be paid to the colorectal cancer in stomach cancer patients.

Intracystic Papillary Carcinoma in the Male Breast: A Case Report / 한국유방암학회지

Intracystic papillary carcinoma of the breast is a variant of ductal carcinoma in situ (DCIS) characterized by the presence of papillary carcinoma within a cystically dilated duct. DCIS of the male breast is an uncommon disease, accounting for approximately 7% of all male breast carcinomas. Most DCIS in men is of the papillary type. We experienced one case of intracystic papillary carcinoma in the right breast of a 49-yr-old male and report the case with a review of the literature.

Malignant Fibrous Histiocytoma in the Breast: A Case Report / 한국유방암학회지

Malignant fibrous histiocytoma is the most common form of soft tissue sarcoma during middle and late adulthood in the deep connective tissues of the extremities, abdominal cavity, and retroperitoneum. Primary breast sarcoma is a rare disease entity, comprising less than 1% of all breast malignancies. Malignant fibrous histiocytoma of the breast is very rare. We presented one case of a malignant fibrous histiocytoma of the right breast in a 49-year-old woman and report the case with a review of the literature.

Choledochocele Associated with Recurrent Pancreatitis in an Adult

Choledochocele is a rare cystic dilatation of the distal common bile duct in the wall of the duodenum. It is a type III choledochal cyst among the five types according to Todani's modification of the Alonso-Lej classification, and this type lll cyst comprises less than 4% of all choledochal cysts. We experienced one case of choledochocele in a 41-year-old woman who presented with recurrent pancreatitis, and we report on this case, along with a review of the literature.

Colon Obstruction due to Colonic Metastasis of a Breast Carcinoma

Breast cancer is a common malignancy in women and metastasizes to the liver, the lung, the brain, and the bone, but metastasis to the colon is rare. We describe a 58-year-old woman with colon metastasis of breast cancer. She was diagnosed with right colon cancer, and during investigation for colon cancer, we found a breast cancer. She received a palliative right hemicolectomy due to obstruction before chemotherapy. The histology of the tissue taken from the right colon was shown to be the same as that of the left breast mass. This is a case of colonic metastasis from breast cancer and we report this case with a review of literature.

Laparoscopic Surgery for Splenic Flexure Colon Cancer

Purpose: While a carcinoma of the splenic flexure is uncommon, is associated with a high risk of obstruction, and has a dual lymphatic drainage system, A COST study excluded transverse colon cancer, including splenic flexure colon cancer. This study reviews our experience with splenic flexure colon cancer treated laparoscopically and discusses a appropriate, safe laparoscopic surgical procedure. Methods: The authors reviewed the medical records of patients who underwent laparoscopic surgery for splenic flexure colon cancer from January 1995 to June 2006. The splenic flexure colon was defined as 5 cm from the splenic flexure proximally and distally by using radiologic studies. Curative surgery for splenic flexure colon cancer was defined as: primary cancer removal, a safe resected margin, no metastasis, and a complete lymphadenectomy including high ligation of left colic artery and of the left branch of the middle colic artery. Results: A total of 407 patients underwent laparoscopic surgery for colon cancer; among them, 15 patients underwent a laparoscopic left colectomy for splenic flexure colon cancer. The mean age of the patients was 63.8 years, and the male-to-female ratio was 9:6. The mean operation time was 325.3+/-95.1 minutes, and the average hospital stay was 15.8+/-4.9 days. The average number of harvested lymph nodes was 12.3+/-9.7, the average distal resection margin was 15.3+/-7.6 cm, and the average proximal margin was 10.7+/-3.2 cm. One case of chyle discharge and one case of ileus developed, but were treated conservatively. There was no surgical mortality. Conclusions: A laparoscopic left colectomy for splenic flexure colon cancer is a technically feasible and safe procedure with acceptable short-term outcomes in experienced hands.

Analysis of the Diagnostic Maneuver and Timing of Operation in Adult Intussusception

PURPOSE: Intestinal intussusception in adults is a rare entity and its clinical course and etiology differ from pediatric counterpart. About 90% have a primary pathologic lesion, especially malignancy consists of etiology as 30% in small bowel and 66% in large bowel. The purpose of this study is to investigate of accurate diagnosis, treatment, and timing of operation by review of clinical symptom, physical examination, laboratory finding, pathologic finding, and operation finding of adult intussusception patients. METHODS: We studied 20 adult patients who were diagnosed as intussusception between July 1993 and September 2005. Intussusception by operation and rectal prolapse were excluded. Clinicopatholgic findings were analyzed retrospectively through the medical record. RESULTS: There was 15 males and 5 females in all 20 patients, and mean age was 52.3 years with a range of 29 to 78 years. Preoperative diagnosis was suspected in 14 of 20 patients (70%). We performed emergency operation in 8 cases (40%) and elective operation in 12 cases (60%). Two cases of them which preoperative diagnosis were strangulation and peritonitis accompanied with small bowel necrosis and leukocytosis. There were 12 small bowel lesions (60%) and 6 colonic lesions (30%). In two cases, there were no primary lesions. Of the cases with a defined cause, 12 cases were malignant (60%) and 6 cases were benign (30%). CONCLUSION: The most useful diagnostic method is computed tomography to reveal adult intussusception. Two cases of all were strangulated and also had a leukocytosis. In adult intussusception, most common cause is malignancy. If there is no evidence of strangulation such as leukocytosis, we recommend that elective surgery is adequate.

Laparoscopic Surgery for Colorectal Cancer in Elderly Patients

PURPOSE: Elderly colorectal cancer patients may have increased surgical morbidity and mortality due to comorbidity and compromised cardiopulmonary reserves. The aim of this study is to compare the safety and the outcomes of laparoscopic surgery for colorectal cancer in patients of 70 years of age and older to those of patients younger than 70 years of age. METHODS: From August 2004 to April 2006, the authors retrospectively analyzed the medical records of patients who underwent laparoscopic surgery for colorectal cancer. RESULTS: The elderly group included 35 cases, and the younger group included 67 cases. The mean age of the elderly group was 74.4+/-4.1, and that of the younger group was 58.2+/-9.5. Sixty-three percent (63%) of the elderly group and 27% of the younger group had co- morbidity. The mean operation time in the elderly group was 299.9+/-121.0 minutes, and that in the younger group was 295.1+/-110.8 minutes. The mean number of harvested lymph nodes was 17.7+/-8.6 in the elderly group and 19.4+/-9.8 in the younger group. The day of diet start was the 4.1+/-0.6 postoperative day in the elderly group and the 4.4+/-1.4 day in the younger group. Hospital stay was 16.0+/-7.6 in the elderly group and 15.5+/-4.6 days in the younger group. There were no statistical differences in terms of operation time, number of harvested lymph nodes, blood loss at operation, day of flatus passing, diet start, hospital stay, and complications. There was no surgical mortality in either groups. CONCLUSIONS: Laparoscopic surgery for colorectal cancer is a safe and effective treatment option in elderly patients.
