Endoscopic Histoacryl injection for esophagojejunostomy leakage after total gastrectomy in patients with gastric cancer

Purpose@#Esophagojejunostomy leakage after total gastrectomy for gastric cancer is one of the most serious and sometimes life-threatening adverse events. The purpose of this study was to evaluate complications after total gastrectomy in patients with gastric cancer during the period when Histoacryl (B. Braun) injection was performed. Therapeutic outcome of endoscopic Histoacryl injection for esophagojejunostomy leakage was also determined. @*Methods@#This was a single-center retrospective study. Between January 2016 and December 2021, clinicopathologic characteristics and surgical outcomes of 205 patients who underwent total gastrectomy were investigated. Baseline characteristics and clinical outcomes of 10 patients with esophagojejunostomy leakage were also investigated. @*Results@#Postoperative complication and mortality rates of total gastrectomy in 205 patients were 25.4% and 0.9%, respectively. Serious complications more than Clavien-Dindo IIIb accounted for 6.3%. Ten (4.9%) esophagojejunostomy leakages occurred in 205 patients. Among 10 esophagojejunostomy leakage patients, endoscopic Histoacryl injection was performed on eight patients and leakage was successfully managed with endoscopic Histoacryl injection in seven patients (87.5%). Mean postinjection hospital stay of seven successfully managed patients was 13.8 days. They were able to drink water at 1–6 days after injection.Among eight patients with endoscopic Histoacryl injection, six patients were injected once and two patients were injected three times. @*Conclusion@#Endoscopic Histoacryl injection for esophagojejunostomy leakage after total gastrectomy can be considered as a useful treatment for some selected cases.

Local complications are related to poor long-term outcome in patients undergoing curative gastrectomy for advanced gastric cancer

Purpose@#The present study was performed to investigate the effects of local complications (LC) on long-term survival and cancer recurrence in patients undergoing curative gastrectomy for gastric cancer. @*Methods@#We analyzed 2,627 patients after curative gastrectomy for gastric cancer between January 2001 and December 2006. Patients were classified into groups no complications (NC), LC, or systemic complications (SC). @*Results@#Among the 2,627 patients, 475 patients developed complications (LC group [n=374, 14.2%] and SC group [n=101, 3.9%]). The 5-year cancer-specific survival rate was significantly poorer in the LC group compared to the NC and SC groups (LC, 78.0%; NC, 85.4%; SC, 80.2%; P=0.007). The occurrence of LC was identified as a significant independent prognostic factor for overall and cancer-specific survival (hazard ratio [HR], 2.08; 95% confidence interval [CI], 1.46–2.97; P=0.001 and HR, 1.77; 95% CI, 1.12–2.81; P=0.015). The tumor recurrence rates were higher in the LC group than the in other two groups (LC, 23.5%; NC, 15.4%; SC, 15.8%; P<0.001). The occurrence of LC was an independent predictor of tumor recurrence in patients undergoing curative gastrectomy for gastric cancer (HR, 1.55; 95% CI, 1.11–2.17; P=0.011). @*Conclusion@#LC are associated with adverse long-term outcomes in patients after curative gastrectomy for advanced gastric cancer.

Extradural Spinal Arachnoid Cyst as a Cause of Cauda Equina Syndrome in a Child / 대한신경손상학회지

Although spinal arachnoid cysts are relatively common findings observed incidentally in adults, they are much rarely reported in children. They are usually asymptomatic and are mainly located in the middle and lower thoracic regions. However, in rare circumstances, these cysts can cause mass effects that lead to neurologic symptoms. We report the rare case of a spinal extradural arachnoid cyst in a 12-year-old boy who showed signs and symptoms of cauda equina syndrome. Magnetic resonance imaging of the lumbar spine revealed a huge extradural arachnoid cyst extending from L2 to L5. Emergent laminectomy and repair of dural defect was performed after total resection of the extradural arachnoid cyst. There were no postoperative complications. Total recovery was achieved 6 months after surgery. Here, we report this rare case with a review of the literature.

The pattern of postoperative quality of life following minimally invasive gastrectomy for gastric cancer: a prospective cohort from Korean multicenter robotic gastrectomy trial

Purpose@#Quality of life (QOL) has become important in the trend of emphasizing patient satisfaction. This study aimed to evaluate the QOL in patients who underwent laparoscopic or robotic gastrectomy for gastric cancer. @*Methods@#A prospective trial was performed involving patients who underwent laparoscopic or robotic gastrectomy for primary gastric cancer at 11 hospitals in Korea. Within this comparative trial, QOL, postoperative pain, and long-term complications were exanimated. The quality-of-life questionnaire (QLQ)-C30 and QLQ-STO22 developed by the European Organization for Research and Treatment of Cancer were used for the QOL survey. We compared the data after dividing it into several types of characteristics as follows; device (robotic or laparoscopic), operation type, pathological stage, and sex.Biased components were extracted by logistic regression analysis. Propensity score matching was applied to the data set with the biased components. @*Results@#In total, 434 patients (211 for laparoscopic surgery and 223 for robotic surgery) were enrolled, out of which 321 patients who responded to both preoperative and postoperative surveys were selected for analysis. Robotic gastrectomy was not different from laparoscopic gastrectomy with respect to postoperative QOL. Distal gastrectomy showed better scores than total gastrectomy in terms of role functioning, social functioning, fatigue, nausea/vomiting, pain, dyspnea, constipation, financial difficulties, dysphagia, eating restrictions, anxiety, taste, and body image. Male patients showed better scores on the 19 scales compared to female patients. @*Conclusion@#Robotic and laparoscopic approaches for gastric cancer surgery did not differ from each other with respect to QOL. Distal gastrectomy resulted in better QOL than total gastrectomy.

Comparison of Interferon-gamma Secretion by Stimulated NK Cells and T cells from Healthy Subjects

Interferon-γ (IFN-γ) is an important cytokine produced by natural killer (NK) cells and T cells in response to various stimuli. The levels of IFN-γ secreted after stimulation of NK cells using a recombinant cytokine is represented as one of functions of NK cells. Recently, a method for evaluating NK cell activity in whole blood samples was developed. The levels of IFN-γ secreted after NK cell stimulation with PROMOCA™ (ATGen, Korea) and T cell stimulation with phytohemagglutinin (PHA) were compared using two different commercial kits: NK Vue Gold (ATGen, Korea) and QuantiFERON-TB Gold In-Tube (Cellestis, Australia). Participants included 43 healthy individuals. Whole blood samples were incubated with either PROMOCA, a recombinant cytokine that specifically activates NK cells, or with PHA. IFN-γ levels in the supernatants were measured by ELISA. The level of IFN-γ by PROMOCA stimulation (PROMOCA IFN-γ) was more varied than that by stimulation with PHA (PHA IFN-γ) (median 1,544.4 pg/mL [ range 193.7–2,530.9] vs. median 2,470.1 pg/mL [ 2,250.1–2,874.4] P=0.0001). The median of PHA IFN-γ/PROMOCA IFN-γ ratio was 1.9 (1.1–12.4). There was a significant difference in levels of IFN-γ secreted after stimulation with PROMOCA or PHA in the healthy population.

Risk Factors for the Development of Incisional Hernia in Mini-laparotomy Wounds Following Laparoscopic Distal Gastrectomy in Patients with Gastric Cancer

PURPOSE: To determine the incidence of incisional hernia (IH) in mini-laparotomy wounds and analyze the risk factors of IH following laparoscopic distal gastrectomy in patients with gastric cancer. MATERIALS AND METHODS: A total of 565 patients who underwent laparoscopic distal gastrectomy for gastric cancer at Dong-A University Hospital, Busan, South Korea, between June 2010 and December 2015, were enrolled. IH was diagnosed through physical examination or computed tomography imaging. Incidence rate and risk factors of IH were evaluated through a long-term follow-up. RESULTS: Of those enrolled, 16 patients (2.8%) developed IH. The median duration of follow-up was 58 months (range, 25–90 months). Of the 16 patients with IH, 15 (93.7%) were diagnosed within 12 months postoperatively. Multivariate analysis showed that female sex (odds ratio [OR], 3.869; 95% confidence interval [CI], 1.325–11.296), higher body mass index (BMI; OR, 1.229; 95% CI, 1.048–1.422), and presence of comorbidity (OR, 3.806; 95% CI, 1.212–11.948) were significant risk factors of IH. The vast majority of IH cases (15/16 patients, 93.7%) developed in the totally laparoscopic distal gastrectomy (TLDG) group. However, the type of surgery (i.e., TLDG or laparoscopy-assisted distal gastrectomy) did not significantly affect the development of IH (P=0.060). CONCLUSIONS: A median follow-up of 58 months showed that the overall incidence of IH in mini-laparotomy wounds was 2.8%. Multivariate analysis showed that female sex, higher BMI, and presence of comorbidity were significant risk factors of IH. Thus, surgeons should monitor the closure of mini-laparotomy wounds in patients with risk factors of IH undergoing laparoscopic distal gastrectomy.

T-Cell Immunoglobulin Mucin 3 Expression on Tumor Infiltrating Lymphocytes as a Positive Prognosticator in Triple-Negative Breast Cancer / 한국유방암학회지

PURPOSE: T-cell immunoglobulin and mucin domain-containing molecule 3 (TIM-3) is an emerging immune response molecule related to T-cell anergy. There has been tremendous interest in breast cancer targeting immune checkpoint molecules, especially in the triple-negative breast cancer (TNBC). This study was designed to investigate TIM-3 expression on tumor infiltrating lymphocytes (TILs), its relationships with clinicopathological para-meters and expression of programmed death receptor 1 (PD-1)/programmed death receptor ligand 1 (PD-L1), and its prognostic role. METHODS: Immunohistochemistry on tissue microarray blocks produced from 109 samples of invasive ductal carcinoma type TNBC was performed with antibodies toward TIM-3, PD-1, PD-L1 and breast cancer-related molecular markers. Associations between their expression and clinicopathological parameters as well as survival analyses were performed. RESULTS: TIM-3 was expressed in TILs from all 109 TNBCs, consisting of 17 cases ( 51%). High TIM-3 was significantly correlated with younger patients (p=0.0101), high TILs (p=0.0029), high tumor stage (p=0.0018), high PD-1 (p=0.0001) and high PD-L1 (p=0.0019), and tended to be associated with higher histologic grade, absence of extensive in situ components and microcalcification. High TIM-3 expression was significantly associated with a combinational immunophenotype group of high PD-L1 and high PD-1 (p < 0.0001). High TIM-3 demonstrated a significantly better disease-free survival (DFS) (p < 0.0001) and longer overall survival (OS) (p=0.0001), together with high TILs and high PD-1. In univariate survival analysis, high TIM-3 showed reduced relapse risk (p < 0.0001) and longer OS (p=0.0003), together with high PD-1 expression. In multivariate analysis, high TIM-3 was statistically significant in predicting prognosis, showing better DFS (hazard ratio [HR], 0.0994; 95% confidence interval [CI], 0.0296–0.3337; p=0.0002) and longer OS (HR, 0.1109; 95% CI, 0.0314–0.3912; p=0.0006). CONCLUSION: In this study, we demonstrate that TIM-3 expression is an independent positive prognostic factor in TNBC, despite its association with poor clinical and pathologic features.

Improper Use of Thrombolytic Agents in Acute Hemiparesis Following Misdiagnosis of Acute Ischemic Stroke / 대한신경손상학회지

OBJECTIVE: Acute hemiparesis is often an early presentation of acute ischemic stroke, though it can occur in various disorders. This study aimed to investigate the improper use of thrombolytic agents for patients with acute hemiparesis, following the misdiagnosis of acute ischemic stroke. METHODS: We analyzed the clinical and radiological data of nine patients initially misdiagnosed with cerebral stroke in the emergency room from May 2013 to January 2017. All the patients were treated with tissue plasminogen activator (TPA) owing to the presence of acute hemiparesis. Subsequently, emergent computed tomography scan showed no intracranial hemorrhage. Clinical findings including neurological deficits, clinical course, and related complications were detected and analyzed. RESULTS: Acute hemiparesis was observed in the following conditions: spontaneous spinal epidural hematoma, Brown-Séquard syndrome caused by cervical disc herniation, cervical epidural abscess, hypoglycemia in the presence of an old stroke, and seizure or convulsion disorder. Although acute hemiparesis was regarded as a contraindication, inappropriate TPA administration did not aggravate the neurological condition in any of the patients who required surgery. CONCLUSION: Upon presentation of acute hemiparesis, various conditions mimicking cerebral stroke should be considered to avoid misdiagnosis. We suggest that physicians should exercise caution when prescribing thrombolytic agents.

Laparoscopic Reinforcement Suture (LARS) on Staple Line of Duodenal Stump Using Barbed Suture in Laparoscopic Gastrectomy for Gastric Cancer: a Prospective Single Arm Phase II Study

PURPOSE: Laparoscopic gastrectomy is accepted as a standard treatment for patients with early gastric cancer in Korea, Japan, and China. However, duodenal stump leakage remains a fatal complication after gastrectomy. We conducted a prospective phase II study to evaluate the safety of the new technique of laparoscopic reinforcement suture (LARS) on the duodenal stump. MATERIALS AND METHODS: The estimated number of patients required for this study was 100 for a period of 18 months. Inclusion criteria were histologically proven gastric adenocarcinoma treated with laparoscopic distal or total gastrectomy and Billroth II or Roux-en-Y reconstruction. The primary endpoint was the incidence of duodenal stump leakage within the first 30 postoperative days. The secondary endpoints were early postoperative outcomes until discharge. RESULTS: One hundred patients were enrolled between February 2016 and March 2017. The study groups consisted of 65 male and 35 female patients with a mean age (years) of 62.3. Of these, 63 (63%) patients had comorbidities. The mean number of retrieved lymph nodes was 38. The mean operation time was 145 minutes including 7.8 minutes of mean LARS time. There was no occurrence of duodenal stump leakage. Thirteen complications occurred, with one case of reoperation for splenic artery rupture and one case of mortality. CONCLUSIONS: Based on the results of this prospective phase II study, LARS can be safely performed in a short operation period without development of duodenal stump leakage. A future randomized prospective controlled trial is required to confirm the surgical benefit of LARS compared to non-LARS.

Are prophylactic antibiotics necessary in elective laparoscopic cholecystectomy, regardless of patient risk?

PURPOSE: The average rate of surgical site infections (SSIs) for laparoscopic cholecystectomy (LC) has been reported in the literature to be between 0.4% and 6.3%. Also, these recent reviews have concluded that a prophylactic antibiotics for elective LCs in low-risk patients is not useful, but there were no results in high-risk patients. METHODS: The aim of this study was to investigate the role of a single dose of first-generation cephalosporin as a prophylactic antibiotic for patients undergoing elective LC, regardless of patient risk. This randomized clinical trial was conducted from October 2013 to December 2014 by single surgeon at our hospital. Patients were randomized into two groups by following method. Odd-numbered patients (group A) received 1-g cefazolin intravenously within 30 minutes before incision, whereas even-numbered patients (group B) received normal saline intravenously instead of prophylactic antibiotics, with the aim of including 100 patients in each group. SSIs were recorded and compared between the groups. RESULTS: There were no differences in preoperative demographics and postoperative findings between the groups. There were no superficial and deep SSIs in either group, 9 cases of superficial seromas developed (4.5%) in the cohort: 4 in group A (4%) and 5 in group B (5%). There were no significant associations between SSIs and the use of prophylactic antibiotics in either group. Additionally, the high-risk group did not show a significantly increased rate of SSIs. CONCLUSION: Based on our study, prophylactic antibiotics are not necessary in elective LC, regardless of patient risk.

Severe Retrolisthesis at the Adjacent Segment after Lumbar Fusion Combined with Dynamic Stabilization / 대한신경손상학회지

Lumbar fusion using the pedicle screw system is a popular operative procedure, with favorable clinical results and high fusion rates. However, the risk of adjacent segment disease after lumbar fusion is problematic. We report a complicated case of severe retrolisthesis at L3-4 level following dynamic interspinous process stabilization at L2-3 level and a fusion at L4-5 level. The radiological and clinical findings of this complication are discussed, and a review of the literature is presented.

Laparoscopic reinforcement suture on staple-line of duodenal stump using barbed suture during laparoscopic gastrectomy for gastric cancer

PURPOSE: Duodenal stump fistula (DSF) is a serious complication after gastrectomy for gastric cancer. Although risk evaluation and management of DSF were presented by some investigators, there was no technical attempt has been made to prevent DSF during laparoscopic gastrectomy until now. METHODS: Consecutive 99 patients were enrolled from April 2014 to February 2016 in 2 institutes. All patients were performed laparoscopic gastrectomy for gastric cancer. After cutting of duodenal stump, laparoscopic reinforcement suture (LARS) commenced with continuous invagination method or interrupted method by barbed suture. Clinicopathologic features and postoperative outcomes were analyzed. RESULTS: Fifty-six patients had comorbidity including 5 patients with duodenal ulcer. Most patients were performed distal gastrectomy with B-II, and 10 patients total gastrectomy with Roux en Y esophagojejunostomy. Although there were 2 esophagojejunostomy leakage and 1 artificial lesser curvature leakage, DSF did not occurred at all in this study. Mean operation time was 3 hours and mean LARS procedure time was 8 minutes. CONCLUSION: LARS of duodenal stump can be considered as one of prevention methods of DSF during laparoscopic gastrectomy for gastric cancer. So this new technique will be necessary to appropriately evaluate by prospective randomized controlled trial in the future.

Effect of visceral fat area on outcomes of laparoscopyassisted distal gastrectomy for gastric cancer: subgroup analysis by gender and parameters of obesity

PURPOSE: The aim of this study was to investigate the impact of the visceral fat area (VFA) of patients with gastric cancer undergoing laparoscopic surgery on operative outcomes such as number of retrieved lymph nodes (LNs) and operative time. METHODS: We retrospectively reviewed the medical records and the CT scans of 597 patients with gastric cancer who underwent laparoscopy assisted distal gastrectomy (LADG) with partial omentectomy and LN dissection (>D1 plus beta). Patients were stratified by gender, VFA, and body mass index (BMI), and the clinicopathologic characteristics and operative outcomes were evaluated. Multiple linear regression analysis was used to assess the effects of VFA and BMI on the number of retrieved LNs and operative time in male and female patients. RESULTS: The mean number of retrieved LNs was significantly decreased for both male and female patients with high VFA. The operative time was significantly longer for both male and female patients with high VFA. The number of retrieved LNs had a statistically significant negative correlation with VFA in both men and women, but not with BMI. The operative time had a statistically significant positive correlation with VFA in men, whereas the operative time had a statistically significant positive correlation with BMI in women. CONCLUSION: The preoperative VFA of male patients with gastric cancer who undergo LADG may affect the number of retrieved LNs and operative time. VFA was more useful than BMI for predicting outcomes of LADG.

Comprehension of readmission after laparoscopy assisted distal gastrectomy: what are the causes?

PURPOSE: The aim of this study is to evaluate long-term outcomes regarding readmission for laparoscopy-assisted distal subtotal gastrectomy (LADG) compared to conventional open distal subtotal gastrectomy (CODG) for early gastric cancer (EGC). METHODS: Between January 2003 and December 2006, 223 and 106 patients underwent LADG and CODG, respectively, for EGC by one surgeon. The clinicopathologic characteristics, postoperative outcomes, postoperative complications, overall 5-year survival, recurrence, and readmission were retrospectively compared between the two groups. RESULTS: Multiple readmission rate in LADG was significantly less than that in CODG (0.4% vs. 3.8%, P = 0.039), although the readmission rate, reoperation rate after discharge, and mean readmission days were not significantly different between the two groups. Readmission rates of the LADG and CODG groups were 12.6% and 14.2%, respectively. First flatus time and postoperative hospital stay was significantly shorter in the LADG group. However, there was no significant difference in the complication rates between the two groups. Overall 5-year survival rates of the LADG and CODG group were 100% and 99.1% (P = 0.038), respectively. CONCLUSION: Compared to the CODG group, the LADG group has several advantages in surgical short-term outcome and some benefit in terms of readmission in surgical long-term outcome for patients with EGC, even though the oncologic outcome of LADG is similar to that of CODG over 5 years.

Prospective randomized controlled trial (phase III) to comparing laparoscopic distal gastrectomy with open distal gastrectomy for gastric adenocarcinoma (KLASS 01) / 대한외과학회지

A randomized controlled trial to evaluate the long-term outcomes of laparoscopic distal gastrectomy for gastric cancer is currently ongoing in Korea. Patients with cT1N0M0-cT2aN0M0 (American Joint Committee on Cancer, 6th edition) distal gastric cancer were randomized to receive either laparoscopic or open distal gastrectomy. For surgical quality control, the surgeons participating in this trial had to have performed at least 50 cases each of laparoscopy-assisted distal gastrectomy and open distal gastrectomy and their institutions should have performed more than 80 cases each of both procedures each year. Fifteen surgeons from 12 institutions recruited 1,415 patients. The primary endpoint is overall survival. The secondary endpoints are disease-free survival, morbidity, mortality, quality of life, inflammatory and immune responses, and cost-effectiveness (ClinicalTrials.gov ID: NCT00452751).

Comparative Study of Hand-Sutured versus Circular Stapled Anastomosis for Gastrojejunostomy in Laparoscopy Assisted Distal Gastrectomy

PURPOSE: Mechanical stapler is regarded as a good alternative to the hand sewing technique, when used in gastric reconstruction. The circular stapling method has been widely applied to gastrectomy (open orlaparoscopic), for gastric cancer. We illustrated and compared the hand-sutured method to the circular stapling method, for Billroth-II, in patients who underwent laparoscopy assisted distal gastrectomy for gastric cancer. MATERIALS AND METHODS: Between April 2009 and May 2011, 60 patients who underwent laparoscopy assisted distal gastrectomy, with Billroth-II, were enrolled. Hand-sutured Billroth-II was performed in 40 patients (manual group) and circular stapler Billroth-II was performed in 20 patients (stapler group). Clinicopathological features and post-operative outcomes were evaluated and compared between the two groups. RESULTS: Nosignificant differences were observed in clinicopathologic parameters and post-operative outcomes, except in the operation times. Operation times and anastomosis times were significantly shorter in the stapler group (P=0.004 and P<0.001). CONCLUSIONS: Compared to the hand-sutured method, the circular stapling method can be applied safely and more efficiently, when performing Billroth-II anastomosis, after laparoscopy assisted distal gastrectomy in patients with gastric cancer.

Long-Term Outcomes and Feasibility with Laparoscopy-Assisted Gastrectomy for Gastric Cancer

PURPOSE: Recently, laparoscopy-assisted gastrectomy (LAG) has been widely accepted modality for early gastric cancer in Korea. The indication of LAG may be extended in an experienced institution. In our institution, the first case of laparoscopy-assisted gastrectomy (LAG) for gastric cancer was performed in May 1998. We retrospectively reviewed the long-term oncologic outcomes over 12 years to clarify the feasibility of LAG for gastric cancer. MATERIALS AND METHODS: The authors retrospectively analyzed 753 patients who underwent LAG for gastric cancer, from May 1998 to August 2010. We reviewed clinicopathological features, postoperative outcomes, mortality and morbidity, recurrence, and survival of LAG for gastric cancer. RESULTS: During the time period, 3,039 operations for gastric cancer were performed. Among them, 753 cases were done by LAG (24.8%). There were 69 cases of total gastrectomy, 682 subtotal gastrectomies, and 2 proximal gastrectomies. According to TNM stage, 8 patients were in stage 0, 619 in stage I, 88 in stage II, and 38 in stage III. The operation-related complications occurred in 77 cases (10.2%). Median follow-up period was 56.2 months (range 0.7~165.6 months). Twenty-five patients (3.3%) developed recurrence, during the follow-up period. The overall 5-year and disease free survival rates were 97.1% and 96.3%, respectively. CONCLUSIONS: The number of postoperative complications and survival rates of our series were comparable to the results from that of other reports. The authors consider LAG to be a feasible alternative for the treatment of early gastric cancer. However, rationale for laparoscopic surgery in advanced gastric cancer has yet to be determined.
