RÉSUMÉ

PURPOSE: Total thyroidectomy with central lymph node dissection (CLND) is a treatment modality of choice for thyroid cancer. Hypocalcemia is the most common complication after total thyroidectomy. The aim of the current study was to determine the association between surgery-related clinical factors and postoperative hypocalcemia. METHODS: A prospective analysis was performed for 101 patients who underwent total thyroidectomy with CLND for papillary cancer from June 2013 to June 2014. Correlation between clinicopathologic factors and postoperative hypocalcemia was analyzed. RESULTS: Based on the postoperative day-2 calcium, 56 patients (55%) developed hypocalcemia and 45 patients (45%) were normal. No significant differences in histopathologic (tumor size, tumor focality, histologic type, number of retrieved lymph nodes, metastatic lymph node, thyroiditis, retrieved parathyroid gland) findings were observed between the hypocalcemia group and normal calcium group. Mean value of the postoperative day-0 parathyroid hormone (PTH) was significantly lower in the hypocalcemia group (hypoca1cemia group: 14.3+/-9.4 pg/mL; normal group: 25.0+/-16.4 pg/mL; P<0.001). In logistic regression analysis, postoperative PTH was a factor significantly affecting postoperative hypocalcemia (OR 0.93; CI: 0.90-0.97; P<0.001). In ROC analysis, the cut-off value of PTH was 19.965 (sensitivity 79%, specificity 58%), and area under the curve (AUC) was 0.709 (95% CI: 0.607-0.811). CONCLUSION: Postoperative PTH was a factor predicting hypocalcemia after total thyroidectomy with CLND. Use of postoperative PTH as a screening tool for prediction of postoperative hypocalcemia would be useful in management of patients with hypocalcemia.

RÉSUMÉ

PURPOSE: Wound infection after an ileostomy reversal is a common problem. To reduce wound-related complications, purse-string skin closure was introduced as an alternative to conventional linear skin closure. This study is designed to compare wound infection rates and operative outcomes between linear and purse-string skin closure after a loop ileostomy reversal. METHODS: Between December 2002 and October 2010, a total of 48 consecutive patients undergoing a loop ileostomy reversal were enrolled. Outcomes were compared between linear skin closure (group L, n = 30) and purse string closure (group P, n = 18). The operative technique for linear skin closure consisted of an elliptical incision around the stoma, with mobilization, and anastomosis of the ileum. The rectus fascia was repaired with interrupted sutures. Skin closure was performed with vertical mattress interrupted sutures. Purse-string skin closure consisted of a circumstomal incision around the ileostomy using the same procedures as used for the ileum. Fascial closure was identical to linear closure, but the circumstomal skin incision was approximated using a purse-string subcuticular suture (2-0 Polysorb). RESULTS: Between group L and P, there were no differences of age, gender, body mass index, and American Society of Anesthesiologists (ASA) scores. Original indication for ileostomy was 23 cases of malignancy (76.7%) in group L, and 13 cases of malignancy (77.2%) in group P. The median time duration from ileostomy to reversal was 4.0 months (range, 0.6 to 55.7 months) in group L and 4.1 months (range, 2.2 to 43.9 months) in group P. The median operative time was 103 minutes (range, 45 to 260 minutes) in group L and 100 minutes (range, 30 to 185 minutes) in group P. The median hospital stay was 11 days (range, 5 to 4 days) in group L and 7 days (range, 4 to 14 days) in group P (P < 0.001). Wound infection was found in 5 cases (16.7%) in group L and in one case (5.6%) in group L (P = 0.26). CONCLUSION: Based on this study, purse-string skin closure after a loop ileostomy reversal showed comparable outcomes, in terms of wound infection rates, to those of linear skin closure. Thus, purse-string skin closure could be a good alternative to the conventional linear closure.

RÉSUMÉ

Since Kalloo and colleagues first reported the feasibility and safety of a peroral transgastric approach in the porcine model in 2004, various groups have reported more complex natural orifice transluminal endoscopic surgery (NOTES) procedures, such as the cholecystectomy, splenectomy and liver biopsy, in the porcine model. Natural orifice access to the abdominal cavity, such as transgastric, transvesical, transcolonic, and transvaginal, has been described. Although a novel, minimally invasive approach to the abdominal cavity is a peroral endoscopic transgastric approach, there are still some challenging issues, such as the risk of infection and leakage, and the method of gastric closure. Hybrid-NOTES is an ideal first step in humans. Human hybrid transvaginal access has been used for years by many surgeons for diagnostic and therapeutic purposes. Here, we report a transvaginal flexible endoscopic appendectomy, with a 5-mm umbilical port using ultrasonic scissors in a 74-year-old woman with acute appendicitis.

RÉSUMÉ

PURPOSE: Histologically, IPMN (intraductal papillary mucinous neoplasm) includes various grades of lesion, from hyperplasia and adenoma to adenocarcinoma. The prognosis is different for each histological grade. The malignant IPMN contain in-situ and invasive carcinoma. The purpose of this study was to investigate the clinicopathologic features and outcome of invasive IPMN. METHODS: 18 patients with invasive IPMN underwent surgical treatment between October 1994 and December 2005 at Samsung Medical Center. The clinical, biochemical and pathologic features were retrospectively analyzed. Survival and the clinicopathologic features were compared between invasive IPMN and PDAC of the well differentiated type (wd, n=27) and carcinoma in-situ (CIS, n=10). RESULTS: The preoperative CA19-9 level and total bilirubin level of invasive IPMN patients was statistically higher than those of the CIS patients. The tumor size of invasive IPMN was larger than that of PDAC (wd) (P=0.038). The median survival of patients with invasive IPMN was 31.0 month. The 5-year survival rates of patients with PDAC (wd) and invasive IPMN were 35.5% and 41.7%, respectively (P= 0.237). CONCLUSION: there were no differences for invasive IPMN and PDAC (wd) except for tumor size. The survival in patients with surgical resected invasive IPMN was similar to that of the patients with surgical resected PDAC (wd).

RÉSUMÉ

PURPOSE: The prognosis for patients with liver metastases (LM) from colorectal cancer is significantly influenced by the clinician's decision. Recently, there have been remarkable advances in treatment of LM, so there can be some changes in therapeutic modalities. We performed a comparative study between operated and non-operated groups of patients with LM to analyze the clinical outcome. METHODS: From Feb. 2001 to Feb. 2006, 27 patients with LM underwent a hepatectomy, and 113 patients received non-surgical therapy. thirteen hepatectomized cases among the 27 patients had multiple LM. The outcomes of those 13 patients (Group A) were retrospectively compared to those of the non-operated group (Group B, n=21), which had had potentially resectable LM at the initial diagnosis or after chemotherapy, but didn't undergo hepatic resection. RESULTS: After a median follow-up duration of 31.3 months, the estimated 3-years overall survival (OS) rates were 76.9% and 14.3% in group A and B, respectively (P=0.0001). In the stepwise Cox multivariate regression analysis, factors such as the absence of hepatic resection and a greater diameter of the liver mass independently influenced the poor survival (P=0.005 and P=0.012 respectively). Additionally, two radiologists evaluated the intraoperative ultrasonographic (IOUS) results. IOUS detected new metastatic lesions in 4/13 (30%) patients. There were sub-centimeter metastatic lesions (5~7 mm) and had not been detected in SPIO-enhanced MRI. CONCLUSIONS: Our results compared to palliative chemotherapy suggest that aggressive surgical resection should be performed to increase the survival rate in patients with LM. Additionally, the treatment plan for LM patients should be discussed with the gastroenterololgist, the radiologist, the oncologist, and the surgeon.
