RESUMO

PURPOSE: We investigated complications after laparoscopic sentinel basin dissection (SBD) for patients with gastric cancer who were enrolled in a quality control study, prior to the phase III trial of sentinel lymph node navigation surgery (SNNS). MATERIALS AND METHODS: We analyzed prospective data from a Korean multicenter prerequisite quality control trial of laparoscopic SBD for gastric cancer and assessed procedure-related and surgical complications. All complications were classified according to the Clavien-Dindo Classification (CDC) system and were compared with the results of the previously published SNNS trial. RESULTS: Among the 108 eligible patients who were enrolled in the quality control trial, 8 (7.4%) experienced complications during the early postoperative period. One patient with gastric resection-related duodenal stump leakage recovered after percutaneous drainage (grade IIIa in CDC). The other postoperative complications were mild and patients recovered with supportive care. No complications were directly related to the laparoscopic SBD procedure or tracer usage, and there were no mortalities. The laparoscopic SBD complication rates and patterns that were observed in this study were comparable to those of a previously reported trial. CONCLUSIONS: The results of our prospective, multicenter quality control trial demonstrate that laparoscopic SBD is a safe procedure during SNNS for gastric cancer.

RESUMO

BACKGROUND: We investigated the results of quality control study prior to phase III trial of sentinel lymph node navigation surgery (SNNS). METHODS: Data were reviewed from 108 patients enrolled in the feasibility study of laparoscopic sentinel basin dissection (SBD) in gastric cancer. Seven steps contain tracer injection at submucosa (step 1) and at four sites (step 2) by intraoperative esophagogastroduodenoscopy (EGD), leakage of tracer (step 3), injection within 3 minutes (step 4), identification of at least one sentinel basin (SB) (step 5), evaluation of sentinel basin nodes (SBNs) by frozen biopsy (step 6), and identification of at least five SBNs at back table and frozen sections (step 7). RESULTS: Failure in step 7 (n = 23) was the most common followed by step 3 (n = 15) and step 6 (n = 13). We did not find any differences of clinicopathological factors between success and failure group in steps 1~6. In step 7, body mass index (BMI) was only the significant factor. The success rate was 97.1% in patients with BMI < 23 kg/m2 and 80.3% in those with BMI ≥ 23 kg/m2 (P = 0.028). CONCLUSIONS: Lower BMI group showed higher success rate in step 7. Surgeons doing SNNS should be cautious when evaluating sufficient number of SBN in obese patients.

RESUMO

BACKGROUND: Along with the marked increase in early gastric cancer (EGC) in the Eastern countries, there has been an effort to adopt the sentinel node concept in EGC to preserve gastric function and reduce the occurrence of postoperative complications. Based on promising results from a previous quality control study, this prospective multicenter randomized controlled phase III clinical trial aims to elucidate the oncologic safety of laparoscopic stomach-preserving surgery with sentinel basin dissection (SBD) compared to a standard laparoscopic gastrectomy. METHODS/DESIGN: This trial is an investigator-initiated, open-label, multicenter randomized controlled phase III trial with a non-inferiority design. Patients diagnosed with a single lesion of clinical stage T1N0M0 gastric adenocarcinoma, with a diameter of 3 cm or less are eligible for the present study. A total of 580 patients (290 per group) will be randomized to either laparoscopic stomach-preserving surgery with SBD or standard surgery. The primary end-point is 3-year disease-free survival (DFS) and the secondary endpoints include postoperative morbidity and mortality, quality of life, 5-year DFS, and overall survival. Qualified investigators who completed the prior quality control study are exclusively allowed to participate in this phase III clinical trial. DISCUSSION: The proposed trial is expected to verify whether laparoscopic stomach-preserving surgery with SBD achieves similar oncologic outcomes and improved quality of life compared to a standard gastrectomy in EGC patients. TRIAL REGISTRATION: This study was registered at the NIH ClinicalTrial.gov database ( NCT01804998 ) on March 4th, 2013.

RESUMO

PURPOSE: The goal of oncoplastic breast surgery is to restore the appearance of the breast and improve patient satisfaction. Thus, the assessment of cosmetic results and patient-reported outcomes (PROs) using appropriately constructed and validated instruments is essential. The aim of the present study was to assess the long-term objective cosmetic results and corresponding PROs after oncoplastic breast surgery. METHODS: Cosmetic results were assessed by the patients, a medical panel, and a computer program (BCCT.core). PROs were assessed using BREAST-Q, a questionnaire that measures the perception of patients having breast surgery. The cosmetic results and PROs were analyzed in patients who underwent quadrantectomy and partial breast reconstruction utilizing the latissimus dorsi flap. RESULTS: The mean duration of the follow-up period was 91.6 months (range, 33.3-171.0 months), and mean age of the patients was 51 years old (range, 33-72 years). The mean tumor size was 2.1 cm (range, 0.9-5.5 cm). There was fair agreement between the medical panel and BCCT.core score (K = 0.32, P < 0.001), and a statistically significant correlation between the BCCT.core score and medical panel cosmetic results was identified (r = 0.606, P < 0.001). A better BCCT.core result was related to a higher PRO of each BREAST-Q domain-satisfaction with breasts (R(2) = 0.070, P = 0.039), satisfaction with outcome (R(2) = 0.087, P = 0.021), psychosocial well-being (R(2) = 0.085, P = 0.023), sexual well-being (R(2) = 0.082, P = 0.029), and satisfaction with information (R(2) = 0.064, P = 0.049). CONCLUSION: Our long-term results of oncoplastic surgery achieved a high level of patient satisfaction with good cosmetic results. The medical panel and BCCT.core results correlated well with the PROs of the patients using valid, reliable, and procedure-specific measures.

RESUMO

The clinical application of sentinel node biopsies in early gastric cancer is still controversial even though it appears promising. This study was conducted as a prerequisite quality control for surgical standardization of laparoscopic sentinel basin dissection (SBD) prior to the initiation of a phase III trial.Laparoscopic SBD was performed in patients with preoperative stage T1-2N0 and tumor size <4 cm in diameter. Intraoperative endoscopic submucosal injection of a standardized dual tracer was administered. All retrieved sentinel basin nodes (SBN) were investigated with intraoperative frozen hematoxylin and eosin (H&E) staining. A strict checklist consisting of 7 essential steps was followed during laparoscopic SBD as the quality control study for a phase III trial. Completion of all essential steps in the checklist for 10 cases was used to define a qualified institution.Seven institutions participated and 112 patients were enrolled in this study. However, 4 patients were excluded owing to screening failure. The mean number of cases required for institutional qualification was 15 cases (range, 13-20 cases). Sentinel basins (SB) were detected and dissected in 100 of the 108 patients (92.6%); the median number of SB and SBN was 2 and 7, respectively. Lymph node metastases were detected in 10 patients by postoperative permanent H&E staining and they were detected by SBD in all 10 patients. Frozen results of SBN were compatible with permanent staining reports.Laparoscopic SBD is feasible and demonstrated improved sensitivity in detecting metastatic lymph nodes compared to the previous study. A future phase III randomized trial comparing laparoscopic SBD with organ-preserving gastrectomy and laparoscopic standard gastrectomy seems promising for qualified institutions.

RESUMO

OBJECTIVE: Endoscopic resection (ER) of foregut neuroendocrine tumors (NETs) is increasingly performed instead of surgery. This study aimed to compare the long-term therapeutic outcomes of ER and surgical resection (SR) for foregut NETs. METHODS: From 2002 to 2012, a total of 49 patients with histologically confirmed foregut NETs were treated by ER (n = 33) and SR (n = 16). The clinicopathological characteristics and therapeutic outcomes were evaluated. RESULTS: Of the 33 patients who underwent ER [endoscopic mucosal resection (n = 26), endoscopic mucosal dissection (n = 7)], 32 were diagnosed as NET-G1 and NET-G2, and the other as neuroendocrine carcinoma (NEC). Of the 16 patients who underwent SR, 10 were diagnosed as NET-G1, 2 as NET-G2 and 4 as NEC. The median tumor size was significantly smaller in the ER group compared with the SR group (7 mm vs 19 mm, P = 0.001). In almost all patients treated with ER (32/33), NET invasion was limited to the mucosa and submucosa. Non-curative resections were observed in 24.2% of the patients in the ER group (8/33) and 25.0% in the SR group (4/16). No recurrence occurred in NET cases with positive resection margins by ER. However, all cases of non-curative resection with lymphatic invasion (one in the ER group and four in the SR group) developed liver metastasis during the follow-up despite complete resection, and all these five patients has histologically confirmed NECs. CONCLUSION: NET patients treated by ER may have a good prognosis if the tumor size is small and histologically low grade without lymphatic invasion.

RESUMO

Distant metastasis from papillary thyroid carcinoma (PTC), particularly from papillary thyroid microcarcinoma, is rare. We present a case of perigastric lymph node metastasis from PTC in a patient with early gastric cancer and breast cancer. During post-surgical follow-up for breast cancer, a 56-year-old woman was diagnosed incidentally with early gastric cancer and synchronous left thyroid cancer. Therefore, laparoscopic distal gastrectomy with lymph node dissection and left thyroidectomy were performed. On the basis of the pathologic findings of the surgical specimens, the patient was diagnosed to have papillary thyroid microcarcinoma with perigastric lymph node metastasis and early gastric cancer with mucosal invasion. Finally, on the basis of immunohistochemical staining with galectin-3, the diagnosis of perigastric lymph node metastasis from PTC was made. When a patient has multiple primary malignancies with lymph node metastasis, careful pathologic examination of the surgical specimen is necessary; immunohistochemical staining may be helpful in determining the primary origin of lymph node metastasis.

RESUMO

BACKGROUND/AIMS: This study aimed to compare the outcomes of endoscopic submucosal dissection (ESD) and gastrectomy based on the two sets of indications for ESD, namely guideline criteria (GC) and expanded criteria (EC). METHODS: Between January 2004 and July 2007, 213 early gastric cancer (EGC) patients were enrolled in this study. Of these patients, 142 underwent ESD, and 71 underwent gastrectomy. We evaluated the clinical outcomes of these patients according to the criteria. RESULTS: The complication rates in the ESD and gastrectomy groups were 8.5% and 28.2%, respectively. The duration of hospital stay was significantly shorter in the ESD group than the gastrectomy group according to the GC and EC (p<0.001 and p<0.001, respectively). There was no recurrence in the ESD and gastrectomy groups according to the GC, and the recurrence rates in the ESD and gastrectomy groups were 4.7% and 0.0% according to the EC, respectively (p=0.279). The occurrence rates of metachronous cancer in the ESD and gastrectomy groups were 5.7% and 5.0% according to the GC (p=1.000) and 7.5% and 0.0% according to the EC (p=0.055), respectively. CONCLUSIONS: Based on safety, duration of hospital stay, and long-term outcomes, ESD may be an effective and safe first-line treatment for EGC according to the EC and GC.

RESUMO

Bariatric surgery is considered to be the effective treatment alternative conducted over the lifetime for reducing weight in patients with clinically morbid obesity. For many patients, the benefits of weight loss, including decreases in blood glucose, lipids, and blood pressure as well as increase in mobility, will outweigh the risks of surgical complications. But patients undergoing bariatric surgery have the least risk for long-term diet-related complications as reported in several studies. Thus, with an increasing number of severely obese patients undergoing bariatric surgery, the multidisciplinary healthcare system will need to be managed continuously. Many nutrition support specialists will need to become familiar with the metabolic consequences for the frequent monitoring of nutrition status of the patients. South Korea has a very short history with bariatric surgery, and relatively few studies have been conducted on bariatric surgery. Therefore, the objective of this report was to compare the nutrient intake, weight loss, body fat composition, and visceral fat before and after the bariatric surgery.

RESUMO

PURPOSE: There are two surgical procedures for proximal early gastric cancer (EGC): total gastrectomy (TG) and proximal gastrectomy (PG). This study aimed to compare the long-term outcomes of PG with those of TG. MATERIALS AND METHODS: Between January 2001 and December 2008, 170 patients were diagnosed with proximal EGC at Soonchunhyang University Cheonan Hospital, of which 64 patients underwent PG and 106 underwent TG. Clinicopathologic features, postoperative complications, blood chemistry data, changes in body weight, and oncological outcomes were analyzed and retrospectively compared between both groups. RESULTS: Tumor size was smaller and the number of retrieved lymph nodes was lower in the PG group. The postoperative complication rate was 10.9% in the TG group and 16.9% in the PG group. The incidence of Los Angeles grade C and D reflux esophagitis was significantly higher in the TG group. Hemoglobin level was higher and body weight loss was greater in the TG group at 2, 3, and 5 years postoperatively. The albumin levels at 3 and 5 years were lower in the TG group. There was no significant difference in the 5-year overall survival rates between the two groups (P=0.789). CONCLUSIONS: Postoperative complications and oncologic outcomes were observed to be similar between the two groups. The PG group showed better laboratory data and weight loss than did the TG group. Moreover, severe reflux esophagitis occurred less frequently in the PG group than in the TG group. PG can be considered as an effective surgical treatment for proximal EGC.

RESUMO

Leiomyomas are very common benign tumors in the uterus and it is rare condition to present the retroperitoneal leiomyoma. The author reported a 48-year-old female patient who presented right pelvic mass with urinary incontinence and lower abdominal discomfort. Based on the preoperative imaging, provisional diagnosis was mesenchymal sarcoma. In the intraoperative findings, huge mass abutting to the uterus was observed in retroperitoneal space beneath the right broad ligament. After the exposure the retroperitoneal space, we encountered the well-demarcated tumor measuring 8 × 6 cm in diameter and this tumor attached the right surface of the uterus with fibrotic tissue. Pathologic findings demonstrated retroperitoneal uterine leiomyoma.

RESUMO

AIM: To evaluate the factors associated with liver function alterations after laparoscopy-assisted gastrectomy (LAG) for gastric cancer. METHODS: We collected the data of gastrectomy patients with gastric cancer and divided them into 2 groups: open gastrectomy (OG) and LAG. We also collected the data of patients with colon cancer to evaluate the effect of liver manipulations during surgery on liver function alterations. Serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), total bilirubin, and alkaline phosphatase were measured on the preoperative day and postoperative day 1 (POD1), POD3, POD5, and POD7. RESULTS: No changes in liver function were observed after the operation in patients with colon cancer (n = 121). However, in gastric cancer patients (n = 215), AST and ALT levels increased until POD5 compared to those in colon cancer patients and these findings were observed both in the LAG and OG without a significant difference except at POD1. The mean hepatic enzyme levels at POD1 in the LAG group were significantly higher than those in the OG group (P = 0.047 for AST and P = 0.039 for ALT). The factors associated with elevated ALT on POD1 in patients with gastric cancer were body mass index (P < 0.001), operation time (P < 0.001), intraoperative hepatic injury (P = 0.048), and ligation of an aberrant left hepatic artery (P = 0.052) but not type of operation (OG vs LAG, P = 0.094). CONCLUSION: We conclude that the liver function alteration after LAG may have been caused by direct liver manipulation or aberrant hepatic artery ligation rather than the CO2 pneumoperitoneum.

RESUMO

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.

RESUMO

BACKGROUND: Laparoscopy-assisted distal gastrectomy (LADG) has been applied to the treatment of gastric cancer, and there are now several publications regarding its safety and feasibility. In contrast, there have been few reports on laparoscopy-assisted total gastrectomy (LATG), because this procedure is performed less frequently and is technically more difficult to perform than LADG. The purpose of the present study was to evaluate short-term outcomes in a multicenter study of LATG, as well as its safety and feasibility. METHODS: A retrospective multicenter study was carried out in Korea involving 1,485 patients who underwent laparoscopy-assisted gastrectomy for gastric cancer at 10 institutions between April 1998 and December 2005. Of these patients, 131 underwent LATG. We evaluated and analyzed the short-term outcomes and the clinicopathologic characteristics of the 131 patients. RESULTS: The mean (+/- SD) operation time was 270 +/- 79 min; 1 patient required conversion to an open procedure. The mean number of retrieved lymph nodes was 34.7. The mean duration of hospital stay was 11.3 days, and first intake of soft diet was at 5.8 days. The rate of postoperative morbidity was 19% (25/131 patients); there was no mortality. The most common postoperative morbidity was wound complications at the mini-laparotomy site, and there were 3 cases of anastomotic leakage. Six patients (5%) had recurrence of cancer, and 9 patients (7%) died during the follow-up period. CONCLUSION: Our results suggest that LATG is a safe and feasible procedure for gastric cancer patients. A prospective, multicenter, randomized trial of LATG is needed to confirm the efficacy of this procedure.

RESUMO

Modified right lobe graft with middle hepatic vein reconstruction is commonly carried out in living donor liver transplantation these days. Cadaveric vascular graft has been widely used to maintain good outflow in middle hepatic vein tributaries. However, cadaveric donors are limited in Korea. This problem may be compensated with bovine pericardium. From April 2007, we experienced 4 cases of modified right lobe graft living donor liver transplantation using bovine pericardium. After donor hepatectomy, a 2-cm diameter cylinderic shape was made with the large sized bovine pericardium. V5 and V8 (greater than 5mm in diameter) were anastomosed to the bovine pericardium with end-to-side pattern. After reperfusion, it was anastomosed to the recipient's middle and left hepatic vein trunk. All patients recovered well and are currently remaining good liver function (3 to 11 months). Three cases maintain tolerable middle hepatic venous flow and have no congestion of right anterior sector in enhanced computerized tomography or in Doppler ultrasonography. Bovine pericardium can be one of the alternative materials for middle hepatic vein reconstruction of modified right lobe graft in the area of cadaveric organ shortage.

RESUMO

Surgical resection of liver metastases from colorectal cancer can offer long-term survival and cure in patients with metastatic colorectal cancer isolated to the liver. We present a case of a recurrent liver metastasis from rectal cancer, managed with ante-situm liver resection under total vascular exclusion and venovenous bypass with hypothermic perfusion. A 58-year-old man, who was diagnosed with liver metastasis from rectal cancer underwent a left lateral sectionectomy in January 2006. A recurrent lesion developed 1 year after the first hepatectomy. The tumor was 5 cm in size, locating at segments I, IV, and VIII. It was involved in the origin of middle hepatic vein and retro-hepatic vena cava. We performed ante-situm liver resection under total vascular exclusion and venovenous bypass with hypothermic perfusion. The patient remains well without recurrence for 12 months after the last operation. Ante-situm technique made it easy to approach and completely removes the recurrent lesion locating at hardly accessible site and having the incomplete removal risk by conventional liver resection. The authors also reconfirmed that repeat hepatectomy is valuable in recurrent colorectal liver metastases.

RESUMO

Paraduodenal hernia is a congenital internal hernia caused by abnormal retroperitoneal fixation of the intestinal mesentery. The management of paraduodenal hernia consists of reduction of the herniated intestine and repair of the defect. Recently, laparoscopic surgery has been increasingly performed in abdominal procedures. To evaluate the feasibility and efficacy of laparoscopic repair of paraduodenal hernia, we present our experience in 2 cases of laparoscopic repair, compared with 3 other cases treated with conventional open repair; all 5 cases were successfully treated. All patients had symptoms of intestinal obstruction and were diagnosed by preoperative abdominal computed tomography. Two cases were right-sided hernias, and 3 cases were left sided. Among them, 2 patients with left-sided paraduodenal hernia underwent laparoscopic reduction (LR group) of the herniated small bowel, and the other 3 cases underwent open reduction (OR group). In the LR group, the duration of hospital stay, time to first flatus, and time to first intake of a soft diet were shorter than in the OR group. Thus, with an accurate preoperative diagnosis of paraduodenal hernia, laparoscopic surgery may be a feasible and efficient procedure, with good postoperative outcomes.

RESUMO

While the pathogenesis of varicose veins is assumed to be multifactorial, including the aging process, the etiology, especially in the very young, is strongly linked to genetics and is believed to be associated with improper development and regulation of venous tissue maturation. The aim of this study was to identify the genes whose expression is different in primary varicose veins compared to normal veins in the legs. To test this hypothesis, the differentially expressed gene technique was performed on a large-scale screen of mRNA from varicose and normal veins. Transcriptional products corresponding to cDNA were compared between the two vein types, and one gene showed the greatest differential expression between the samples in all sets of experiments, confirmed by reverse-transcriptase polymerase chain reaction. Octamer-binding transcription factor-1 gene (Oct-1) was upregulated in primary varicose veins. Therefore, we suggest that Oct-1 may play an important role in the development of primary lower extremity varicose veins.

RESUMO

Ethyl pyruvate (EP), a stable lipophilic pyruvate derivative, has been shown to exert anti-inflammatory activities through inhibiting the expression of various pro-inflammatory mediators as well as circulating levels of high mobility group box protein 1 (HMGB1) in a variety of in vitro and in vivo model systems. Necrotic cell death triggers an inflammatory response through release of HMGB1 in the extracellular space due to the membrane rupture. In an effort to better understand the pharmacological action mechanism that could explain the anti-inflammatory properties of EP, we examined the effects of EP on necrotic cell death in A549 lung adenocarcinoma cells in response to glucose deprivation (GD), a common characteristic of the tumor microenvironment. Here we show that EP prevented GD-induced necrosis and HMGB1 release and switched the cell death mode to apoptosis through inhibiting GD-induced CuZn superoxide dismutase release and ROS production. These results suggest that the necrosis-to-apoptosis switch activity of EP may contribute to its anti-inflammatory action and that EP may suppress tumor development possibly through its activity to induce the cell death mode switch from tumor promoting necrotic cell death to tumor suppressive apoptotic cell death.

RESUMO

BACKGROUND: Minimally invasive surgery has been applied to nearly all fields of surgery due to its advantages such as reduced morbidity, a better cosmetic outcome, and early recovery. The recent advances in its technique have allowed us to use modified minimally invasive surgery technique in the field of kidney transplantation. MATERIALS AND METHODS: From January 2004 to March 2006, minimally invasive video-assisted kidney transplantation was carried out in 20 patients. Many clinical variables were compared with the conventional method. The operative procedure began with a 7 to 8 cm skin incision. A laparoscopic balloon dissector was used to create the retroperitoneal space for the placement of the grafted kidney. Vascular anastomosis and ureteroneocystostomy were performed under direct vision and with video-assisted TV monitoring. RESULTS: The average length of the wound was 7.8 cm and it was placed below the belt line. The average operating time was 186 min. Less analgesic was given compared with conventional methods. There was one postoperative complication, a mild lymphocele. All patients showed normalized serum creatinine levels within 4 d. All grafted kidneys showed normal findings on the postoperative ultrasound and renal scans. CONCLUSIONS: Minimally invasive video-assisted kidney transplantation is technically feasible and may offer benefits in terms of better cosmetic outcomes, less pain, and quicker recuperation than conventional kidney transplantation.
