ABSTRACT

Objective@#To investigate short-term efficacy of laparoscopic spleen-preserving splenic hilus lymphadenectomy and left epigastrium mesogastric excision for advanced proximal gastric cancer based on mesangial anatomy.@*Methods@#A case series study was carried out. Case inclusion criteria: (1) patient was confirmed as gastric adenocarcinoma by gastroscopic biopsy before operation; (2) locally advanced gastric cancer was confirmed by abdominal CT before operation; (3) no distant metastases such as liver, lung, and posterior peritoneal lymph nodes, and no tumor directly invading the pancreas, spleen, liver, and colon were verified by superficial lymph node ultrasound, chest and abdominal CT before operation;(4) total gastrectomy or proximal gastrectomy plus D2 lymphadenectomy were performed, and R0 resection was confirmed by postoperative pathology. Exclusion criteria: (1) intraperitoneal dissemination or distant metastasis was found during laparoscopic exploration; (2) No.10 lymph nodes were significantly enlarged or fused into clusters; (3) pathological diagnostic data were incomplete. According to above criteria, the clinicopathological data of 36 patients who underwent laparoscopic spleen-preserving No.10 lymphadenectomy and left epigastrium mesogastric excision based on interspace anatomy for advanced proximal gastric cancer in The First Affiliated Hospital of Zhengzhou University from June 2017 to March 2018 were retrospectively collected and analyzed. The intraoperative conditions, postoperative recovery and complications of patients were analyzed.@*Results@#In 36 patients, the mean age was (59.8±8.0) years, the mean BMI was (23.9±3.5) kg/m2, and 8 cases (22.2%) received preoperative chemotherapy. All the patients underwent successfully the laparoscopic spleen-preserving splenic hilus lymphadenectomy and left epigastrium mesogastric excision. In the examination of postoperative resected specimens, it was found that the mesangial boundary of the upper and posterior part of the stomach was smooth, indicating the efficiency of complete mesangial resection. No case was converted to open operation. The mean time of lymph node dissection and mesangial resection was (34.2±11.4) minutes. The mean blood loss during operation was (44.8±21.3) ml. The mean number of lymph node dissection per patient was 45.6±17.6. The mean number of No. 11p+11d lymph node dissection was 3.1± 2.8 per patient, and 7 patients were pathologically positive with metastasis rate of 19.4% (7/36). The mean number of No.10 lymph node dissection was 2.9±2.5 per patient, and 2 patients were pathologically positive with metastasis rate of 5.6% (2/36). The time to postoperative flatus was (3.8±0.6) days, time to removal of nasogastric was (1.9±0.7) days, time to the first intake of fluid was (3.0±0.4) days, time to removal of drainage tube was (6.0±1.2) days. Postoperative mean hospital stay was (12.8±4.0) days. One case (2.7%) developed pulmonary embolism and 1 case (2.7%) developed gastroplegia after operation. The morbidity of postoperative complication was 5.6% (2/36). No operative site infection, postoperative bleeding and death within postoperative 30-day were observed. All the 36 patients were followed up and the median follow-up was 18 months (12-28 months). Seven patients died of tumor relapse and metastasis (3 cases died within postoperative 1 year) and another 1 case developed colonic cancer 17 months after operation.@*Conclusion@#Laparoscopic spleen-preserving splenic hilus lymphadenectomy and left epigastrium mesogastric excision for advanced proximal gastric cancer based on mesangial anatomy is safe and feasible.

ABSTRACT

OBJECTIVE@#To determine the incidence of surgical site infection (SSI) after abdominal surgery and to further evaluate the related risk factors of SSI in China.@*METHODS@#The multicenter cross-sectional study collected clinical data of all adult patients who underwent abdominal surgery from May 1, 2018 to May 31, 2018 in 30 domestic hospitals, including basic information, perioperative parameters, and incisional microbial culture results. The primary outcome was the incidence of SSI within postoperative 30 days. SSI was classified into superficial incision infection, deep incision infection, and organ/gap infection according to the US Centers for Disease Control and Prevention (CDC) criteria. The secondary outcome variables were ICU stay, postoperative hospital stay, total hospital stay, 30-day mortality and treatment costs. Multivariate logistic regression was used to analyze the risk factors of SSI.@*RESULTS@#A total of 1666 patients were enrolled in the study, including 263 cases of East War Zone Hospital of PLA, 140 cases of Affiliated Hospital of Qingdao University, 108 cases of The First Affiliated Hospital of Nanchang University, 87 cases of Central War Zone Hospital of PLA, 77 cases of West China Hospital, 74 cases of Guangdong General Hospital, 71 cases of Chenzhou First People's Hospital, 71 cases of Zigong First People's Hospital, 64 cases of Zhangjiagang First People's Hospital, 56 cases of Nanyang City Central Hospital, 56 cases of Lanzhou General Hospital of Lanzhou Military Command, 56 cases of Shandong Provincial Hospital, 52 cases of Shangqiu First People's Hospital, 52 cases of People's Hospital of Xinjiang Uygur Autonomous Region, 48 cases of The Second Xiangya Hospital of Central South University, 48 cases of Chinese PLA General Hospital, 44 cases of Affiliated Hospital of Xuzhou Medical University, 38 cases of Hunan Province People's Hospital, 36 cases of Dongguan Kanghua Hospital, 30 cases of Shaoxing Central Hospital, 30 cases of Northern Jiangsu People's Hospital, 29 vases of The First Affiliated Hospital of Zhengzhou University, 27 cases of General Hospital of Tianjin Medical University, 22 cases of Zigong Fourth People's Hospital, 21 cases of The Second Hospital of University of South China, 18 cases of Tongji Hospital, 15 cases of Nanchong Central Hospital, 12 cases of The 901th Hospital of PLA, 11 cases of Hunan Cancer Hospital, 10 cases of Lanzhou University Second Hospital. There were 1019 males and 647 females with mean age of (56.5±15.3) years old. SSI occurred in 80 patients (4.8%) after operation, including 39 cases of superficial incision infection, 16 cases of deep incision infection, and 25 cases of organ/interstitial infection. Escherichia coli was the main pathogen of SSI, and the positive rate was 32.5% (26/80). Compared with patients without SSI, those with SSI had significantly higher ICU occupancy rate [38.8%(31/80) vs. 13.9%(220/1586), P<0.001], postoperative hospital stay (median 17 days vs. 7 days, P<0.001) and total hospital stay (median 22 days vs. 13 days, P<0.001), and significantly higher cost of treatment (median 75 000 yuan vs. 44 000 yuan, P<0.001). Multivariate analysis showed that male rise(OR=2.110, 95%CI:1.175-3.791, P=0.012), preoperative blood glucose level rise(OR=1.100, 95%CI: 1.012-1.197, P=0.026), operative time (OR=1.006, 95%CI:1.003-1.009, P<0.001) and surgical incision grade (clean-contaminated incision:OR=10.207, 95%CI:1.369-76.120, P=0.023; contaminated incision: OR=10.617, 95%CI:1.298-86.865, P=0.028; infection incision: OR=20.173, 95%CI:1.768-230.121, P=0.016) were risk factors for SSI; and laparoscopic surgery (OR=0.348, 95%CI:0.192-0.631, P=0.001) and mechanical bowel preparation(OR=0.441,95%CI:0.221-0.879, P=0.020) were protective factors for SSI.@*CONCLUSIONS@#The incidence of postoperative SSI in patients with abdominal surgery in China is 4.8%. SSI can significantly increase the medical burden of patients. Preoperative control of blood glucose and mechanical bowel preparation are important measures to prevent SSI.

ABSTRACT

Objective To investigate the value of D-dimer in predicting the progression of lower extremity deep venous thrombosis (DVT) during perioperative period of gastrointestinal surgery.Methods Color Doppler ultrasound was used to dynamically monitor the formation and changes of perioperative deep venous thrombosis (DVT) in 239 patients receiving abdominal surgery in our department from Nov 2014 to Aug 2016.Changes of plasma D-dimer were measured,and clinical data of malignant tumor,infection,age,BMI were collected.The relationship between D-dimer elevation and DVT progression was analyzed.Results Lower extremity DVT after surgery developed in 97 patients,and thrombosis progression occurred in 16.6% (16/97).Univariate logistic regression analysis showed that continuous increase of postoperative D-dimer was closely related to the progression of thrombosiss.Multivariate Logistic regression analysis showed that the continuous rise of D-dimer was an independent risk factor for thrombosis.ROC curve analysis showed significantly increased risk of thrombosis progression,when plasma D-dimer polymerization increased >0.87 mg/L on the 3rd day.Conclusion The continuous increase of D-dimer > 0.87 mg/L predicts DVT progression of lower extremity DVT.

ABSTRACT

<p><b>OBJECTIVE</b>To retrospectively evaluate the results of deep sternal wound infection (DSWI) after cardiac surgery.</p><p><b>METHODS</b>Between January 2010 and September 2013, 139 patients suffering from DSWI after median sternotomy. The incidence of DSWI was 0.47% (139/29 574). There were 111 (79.9%) male and 28 (20.1%) female patients. The mean age was (61 ± 11) years, the mean body weight was (74 ± 14) kg. The incidence of postoperative DSWI was 0.88% (91/10 341) after isolated coronary artery bypass grafting (CABG), 0.70% (15/2 143) after valve surgery or other cardiac surgery plus CABG, 0.21% (24/11 429) after valve surgery, 0.15% (3/2 002) after thoracic aortic surgery, and 0.19% (6/3 158) after congenital heart disease. The sternotomy was re-opened and extensive debridement of the wound was performed in all patients. When the wound was clean and there was a bed of fresh granulation tissue, the sternum was rewired. The surgical procedure performed included debridement, drainage, sternal wire reclosure and pectoralis major muscular transpositions depended on the clinical condition of the patient.</p><p><b>RESULTS</b>The in-hospital mortality was 9.3%. Failure of secondary sternal refixation appeared in 15 (10.8%) patients, the reoperation procedure of these 15 patients was pectoralis major muscular transpositions. Other complications included sepsis in 13 patients, perivalvular leakage in 3 patients, and cardiac rupture during the surgical procedure in 3 patients. The mean hospitalization was (39 ± 30) days.</p><p><b>CONCLUSION</b>Deep sternal wound infection is a life-threatening complication after cardiac surgery associated with high morbidity and mortality.</p>

ABSTRACT

ObjectiveTo delineate the anatomy of left gastric artery (LGA) by CT imaging before radical gastrectomy in gastric cancer patients to facilitate intraoperative N07 lymph node dissection.MethodsPreoperative 64 spiral CT angiography (CTA) was applied to observe the origin and course of LGA in gastric cancer patients.ResultsThere were 731 gastric cancer patients undergoing preoperative image evaluation with LGA origin identified from celiac axis in 635 cases. Among those, LGA originated respectively at the crotch of splenic artery and common hepatic artery in 176 cases, from the proximal 1/3 in 292 cases, middle 1/3 in 135 cases and distal 1/3 in 32 cases. There were 9, 28, 27, 4, 4, 1, 4 and 1 cases in whom LGA originates respectively at the angle between celiac trunk and abdominal aorta, from the abdominal aorta, arteria gastrolienalis, splenic artery, common hepatic artery, left hepatic artery, artery gastrohepatica and superior mensentaric artery. LGA has not been observed in 15 cases and the origination of LGA could not be delineated in 3 cases. ConclusionsBeing familiar with the anatomy of LGA as visualized by preoperative CTA in gastric cancer patient, facilitates lymph node dissection around the LGA and decreases iatrogenic injury to vital blood vessels.
