OBJECTIVETo compare clinically relevant postoperative complications after open, laparoscopic, and robotic gastrectomy for gastric cancer.

METHODSClinical data of patients with gastric cancer who underwent gastrectomy between January 1, 2014 and October 1, 2016 at Chinese People's Liberation Army General Hospital were analyzed retrospectively. All the patients were diagnosed by upper endoscopy and confirmed by biopsy without distant metastasis. They were confirmed with R0 resection by postoperative pathology. Patients with incomplete data were excluded. The complications among open group, laparoscopic group and robotic group were compared. The continuous variables were analyzed by one-way ANOVA, and categorical variables were analyzed by χtest or Fisher exact test.

RESULTSA total of 1 791 patients (1 320 males and 471 females) were included in the study, aged from 17 to 98 (59.0±11.6) years, comprising 922 open, 673 laparoscopic and 196 robotic gastrectomies. There were no significant differences among three groups in baseline data (gender, age, BMI, comorbidity, radiochemotherapy) and some of operative or postoperative data (blood transfusion, number of lymph node dissection, combined organ resection, resection site, N stage, postoperative hospital stay). The blood loss in laparoscopic and robotic groups was significantly lower than that in open group[(185.7±139.6) ml and (194.0±187.6) ml vs. (348.2±408.5) ml, F=59.924, P=0.000]. The postoperative complication occurred in 197 of 1 791(11.0%) patients. The Clavien-Dindo II(, III(a, III(b, IIII(a, and IIIII( complications were 5.5%, 4.0%, 1.2%, 0.1%, and 0.2% respectively. The anastomotic leakage (2.4%), intestinal obstruction(1.3%) and pulmonary infection(1.2%) were the three most common complications, followed by wound infection(0.8%), cardiovascular disease(0.7%), anastomotic bleeding (0.7%), delayed gastric emptying (0.6%), duodenal stump fistula(0.5%), intraperitoneal hemorrhage (0.5%), pancreatic fistula (0.3%), intra-abdominal infection(0.2%), chylous leakage (0.1%) and other complications(1.7%). There were no significant differences among three groups as the complication rates of open, laparoscopic and robotic gastrectomy were 10.6%(98/922), 10.8%(73/673) and 13.3%(26/196) respectively (χ=1.173, P=0.566). But anastomotic leakage occurred more common after laparoscopic and robotic gastrectomy compared to open gastrectomy [3.1%(21/673) and 5.1%(10/196) vs. 1.3%(12/922), χ=12.345, P=0.002]. The rate of cardiocerebral vascular diseases was higher in open group[1.3%(12/922) vs. 0.1%(1/673) and 0, χ=8.786, P=0.012]. And the rate of anastomotic bleeding was higher in robotic group [2.0%(4/196) vs. open 0.4%(4/922) and laparoscopic 0.6%(4/673), χ=6.365, P=0.041]. In view of Clavien-Dindo classification, III(a complications occurred more common in laparoscopic group [5.5%(37/673) vs. open 3.3%(30/922) and robotic 2.6%(5/196), χ=6.308, P=0.043] and III(b complications occurred more common in robotic group [3.1%(6/196) vs. open 1.1%(10/922) and laparoscopic 0.7%(5/673), χ=7.167, P=0.028].

CONCLUSIONSMorbidities of postoperative complications are comparable among open, laparoscopic and robotic gastrectomy for gastric cancer. However, in consideration of the high difficulty of anastomosis, the minimally invasive surgery should be performed by more experienced surgeons.

BACKGROUND: To prevent risk of life-threatening stent thrombosis, all patients need to undergo dual antiplatelet therapy (DAPT) for at least 6 weeks to 12 months after stent implantation. If DAPT is continued during noncardiac surgery, there is a risk of severe bleeding at the surgical site. Our study was to assess the risk of bleeding in patients with continued DAPT during orthopedic surgery. METHODS: The clinical data of 78 patients with coronary heart disease who underwent orthopedic surgery from February 2006 to July 2018 were retrospectively analyzed. Prior to orthopedic surgery, DAPT was continued in 16 patients (group I), 24 patients were treated with single antiplatelet therapy (group II), and 26 patients received low-molecular-weight heparin therapy for more than 5 days after the discontinuation of all antiplatelet therapies (group III). Twelve patients were excluded, as they had undergone minimally invasive surgery such as transforaminal endoscopy and vertebroplasty. The perioperative blood loss of each patient was calculated using Nadler's formula and Gross' formula. The intraoperative bleeding volume, total volume of intraoperative bleeding in addition to postoperative drainage, and total blood loss were compared between groups. The level of significance was set at P < 0.05. RESULTS: There were no significant differences between the three groups in age, intraoperative bleeding volume, total volume of intraoperative bleeding in addition to postoperative drainage, and total perioperative blood loss calculated by Nadler's formula and Gross' formula (all P > 0.05). Six patients experienced postoperative cardiovascular complications due to the delayed restart of antiplatelet therapy; one of these patients in group III died from myocardial infarction. CONCLUSIONS Continued DAPT or single antiplatelet treatment during orthopedic surgery does not increase the total intraoperative and perioperative bleeding compared with switching from antiplatelet therapy to low-molecular-weight heparin. However, the discontinuation of antiplatelet therapy increases the risk of serious cardiac complications.

BACKGROUND/AIMS: Endoscopic resection (ER) of superficial esophageal neoplasm (SEN) is a technically difficult procedure. We investigated the clinical outcomes of ER for SEN to determine its feasibility and effectiveness. METHODS: Subjects who underwent ER for SEN at Asan Medical Center between December 1996 and December 2010 were eligible. The clinical features of patients and tumors, histopathological characteristics, adverse events, ER results and survival were investigated. RESULTS: A total of 129 patients underwent ER for 147 SENs. En bloc resection (EnR) was performed in 118 lesions (80.3%). Complete resection (CR) was accomplished in 128 lesions (86.5%), and curative resection (CuR) was performed in 118 lesions (79.7%). The EnR, CR, and CuR rates were significantly greater in the endoscopic submucosal dissection group when compared to those in the endoscopic resection group. Adverse events occurred in 22 patients (17.1%), including bleeding (n=2, 1.6%), perforation (n=12, 9.3%), and stricture (n=8, 6.2%). Local tumor recurrence occurred in 2.0% of patients during a median follow-up of 34.8 months. The 5-year overall and disease-specific survival rates were 94.0% and 97.5%, respectively. CONCLUSIONS: ER is a feasible and effective method for the treatment of SEN as indicated by favorable clinical outcomes.

OBJECTIVEThe history of clinical application of extracorporeal membrane oxygenation (ECMO) has been more than 30 years. But in China, there were only a few ECMO centers with limited successful cases reported by the end of twentieth century. The high morbidities and mortalities in current pediatric ECMO practice are noted in China. Therefore, it is necessary to review the experience on rescue use of ECMO in critically ill pediatric patients.

METHODA retrospective analysis was done for patients who had been receiving ECMO treatment to rescue refractory cardiorespiratory failure from different causes in a hospital between July 2007 and May 2011.

RESULTA total of 12 patients were treated with ECMO; 7 of them were male and 5 female, they aged 6 days to 11 years, weighed 2.8 - 35 (17.21 ± 11.64) kg. The underlying causes of cardiorespiratory failure were as follows: two cases with acute respiratory distress syndrome (ARDS) leading to respiratory failure, 4 with failure of weaning from cardiopulmonary bypass, 3 with fulminant myocarditis, 1 with right ventricular cardiomyopathy leading to repeated cardiac arrest, 1 with preoperative severe hypoxemia, and 1 with anaphylactic shock complicated with massive pulmonary hemorrhage and severe hypoxemia. Of the 12 cases, 3 were established ECMO (E-CPR) while underwent chest compression cardiopulmonary resuscitation (CPR). The mean ECMO support time was 151.75 (15 - 572) h. Seven patients (58.33%) were weaned from ECMO, 6 patients (50.00%) were successfully discharged. Six cases had bleeding from sutures, 2 cases with severe bleeding underwent thoracotomy hemostasis, 2 presented with acute renal failure. Infection was documented in 3 cases, hyperbilirubinemia in 2 cases, lower limb ischemia in 1 case, hyperglycemia in 3 cases, disseminated intravascular coagulation in 1 case, membrane lung leakage in 2 cases, systemic hemolysis in 3 cases, oxygenator failure in 2 cases and oxygenator thrombosis in one case. During the follow-up between 6 months and 4.5 years, 5 patients survived with good quality of life, without any documented central nervous system disorders. One case survived with the right lower extremity disorder from ischemic damage. His motor function has been improved following orthopedic operation at one year after discharge.

CONCLUSIONECMO is a justifiable alternative treatment for reversible severe cardiopulmonary failure in critically ill children.

BACKGROUND/AIMS: Percutaneous coronary intervention (PCI) is often performed therapeutically, and antithrombotic treatment is required for at least 12 months after stent implantation. However, the development of post-PCI upper gastrointestinal bleeding (UGIB) increases morbidity and mortality. We investigated the incidence and risk factors for UGIB in Korean patients within 1 year after PCI. METHODS: The medical records of 3,541 patients who had undergone PCI between January 2006 and June 2012 were retrospectively reviewed. We identified 40 cases of UGIB. We analyzed the incidence and clinical risk factors associated with UGIB occurring within 1 year after PCI by comparing the results for each case to matched controls. The propensity score matching method using age and sex was utilized. RESULTS: UGIB occurred in 40 patients (1.1%). Two independent risk factors for UGIB were a history of peptic ulcer disease (odds ratio [OR], 12.68; 95% confidence interval [CI], 2.70 to 59.66; p=0.001) and the use of anticoagulants (OR, 7.76; 95% CI, 2.10 to 28.66; p=0.002). CONCLUSIONS: UGIB after PCI occurred at a rate of 1.1% in the study population. Clinicians must remain vigilant for the possibility of UGIB after PCI and should consider performing timely endoscopy in patients who have undergone PCI and are suspected of having an UGIB.

OBJECTIVETo evaluate the safety and effectiveness of a modified method of holmium laser enucleation of the prostate (HoLEP)--6-o'clock tunnel HoLEP for the treatment of benign prostate hyperplasia (BPH).

METHODSWe included 112 cases of BPH in this study, 57 treated by 6-o'clock tunnel HoLEP (experimental group) and the other 55 by conventional HoLEP (control group). We compared the operation time, volume of the resected prostatic tissue, intraoperative blood transfusion, volume of bladder irrigation solution, postoperative hemoglobin change, and incidence of urinary incontinence between the two groups.

RESULTSStatistically significant differences were observed between the experimental and control groups in the operation time ([56.01 ± 8.62] min vs [68.65 ± 9.08] min), cases of intraoperative blood transfusion (0 vs 2), volume of bladder irrigation solution ([27.51 ± 3.67] L vs [36.89 ± 6.47] L), postoperative hemoglobin decrease ([10.70 ± 2.50] g/L vs [12.60 ± 3.30] g/L), and cases of postoperative stress-induced urinary incontinence (2 vs 7) (all P <0.05). One-month follow-up revealed smooth urination in both groups of patients but no true urinary incontinence or secondary bleeding in either.

CONCLUSIONModified 6-o'clock tunnel HoLEP can significantly reduce the operation time, bladder irrigation, and intraoperative bleeding, and therefore can be used as a safe and effective option for the treatment of BPH.

To explore the differences in biological characteristics for the small gastrointestinal stromal tumors and the incidence of complications and recurrence between the traditional surgical treatment and endoscopic treatment.
 Methods: We collected the relevant clinical and pathological data from patients who were diagnosed as gastrointestinal stromal tumors with the diameter less than 2 cm by the Department of Pathology of Xiangya Hospital from January 2009 to December 2015. The complications and recurrence after the surgical treatment were analyzed.
 Results: In patients with small gastrointestinal stromal tumors, the proportion of female was higher than that of male (male:female=1:1.69). The median age for patient with this disease was 49 years old and it was more common in middle-aged and elderly. Most lesions were found in the stomach, followed by the esophagus and the small intestine. The small gastrointestinal stromal tumors occurred in the colon and rectum were rare. There was 60.3% (47/78) patients with abdominal pain, 7.7% (6/78) patients with hematochezia or melena, and 98.7% (78/79) with small gastrointestinal stromal tumors' mitotic count ≤5/50 HPF. The positive rates for CD, CD34, DOG-1, actin-smooth, and S-100 were 98.7%, 86.1%, 82.3%, 31.6%, and 24.1%, respectively. Three patients occurred surgical complications, 2 suffered recurrence during the follow-up. There was no significant difference in the incidence of complications and recurrence between the traditional surgical treatment and endoscopic treatment (P>0.05).
 Conclusion: Small gastrointestinal stromal tumors' malignant potential is low, and the recurrence and metastasis rate is low. Its biological behavior tends to be benign. The traditional surgical treatment and endoscopic treatment are both safe and effective for small gastrointestinal stromal tumor. Endoscopic treatment has the advantages in lower cost, shorter hospitalization time, and small trauma. Therefore, endoscopic treatment could be the first choice for small GIST resection under the condition of mature endoscopic technology.

Triple valve surgery is usually complex and carries a reported operative mortality of 13% and 10-yr survival of 61%. We examined surgical results based on our hospital's experience. A total of 160 consecutive patients underwent triple valve surgery from 1990 to 2006. The most common aortic and mitral valve disease was rheumatic disease (82%). The most common tricuspid valve disease was functional regurgitation (80%). Seventy-four percent of the patients were in New York Heart Association (NYHA) class III and IV. Univariate and multivariable analyses were performed to identify predictors of early and late survival. Operative mortality was 6.9% (n=11). Univariate factors associated with mortality included old age, preoperative renal failure, postoperative renal failure, pulmonary complications, and stroke. Of them, postoperative renal failure and stroke were associated with mortality on multivariable analysis. Otherwise, neither tricuspid valve replacement nor reoperation were statistically associated with late mortality. Survival at 5 and 10 yr was 87% and 84%, respectively. Ninety-two percent of the patients were in NYHA class I and II at their most recent follow-up. Ten-year freedom from prosthetic valve endocarditis was 97%; from anticoagulation-related hemorrhage, 82%; from thromboembolism, 89%; and from reoperation, 84%. Postoperative renal failure and stroke were significantly related with operative mortality. Triple valve surgery, regardless of reoperation and tricuspid valve replacement, results in acceptable long-term survival.
