ObjectiveTo investigate factors associated with postoperative complications after laparoscopic radical surgery in rectal cancer.MethodsThe clinical data of patients with rectal cancer performed by the laparoscopic radical resection from February 2013 to December 2016 were analyzed retrospectively. All the data were analyzed by the t test, chi-square test or logistic regression analysis.ResultsThere were 343 patients with rectal cancer performed by the laparoscopic radical resection. The postoperative complications occurred in the 97 (28.3%) patients. The result of univariate analysis showed that the postoperative complications rate was associated with the gender, age, body mass index, preoperative anemia, preoperative comorbidity, location and diameter of tumor, operative time, and surgeon experience (all P<0.050). The results of logistic regression analysis revealed that the gender, age, body mass index, preoperative anemia, preoperative comorbidity, location of tumor, operative time, and surgeon experience were the independent risk factors for the postoperative complications (all P<0.050).ConclusionGender, age, body mass index, preoperative anemia, preoperative comorbidity, location of tumor, operative time, and surgeon experience are independent risk factors for postoperative complications in laparoscopic radical rectal surgery for rectal cancer.
Objective To summarize types of post-mastectomy breast reconstruction and present situation. Method The relevant literatures about post-mastectomy breast reconstruction in recent years were reviewed. Results With the increasing incidence of the breast cancer and the progressing of the treatment methods, it has become a trend for the post-mastectomy breast reconstruction. If the patient’s condition is allowed, the post-mastectomy breast reconstruction can be performed. At present, the post-mastectomy breast reconstruction mainly include the implant based reconstruction, autologous tissue reconstruction, autologous fat transplantation, etc.. There are different options for the breast reconstruction according the indicators and it had the corresponding complications. So the selection of reconstruction technique depend on the individual requirements, determining by the patient choice, advice of the reconstructive surgeon, and anticipated post-mastectomy therapy, particularly the needs for the radiotherapy and chemotherapy, etc.. Conclusions Post-mastectomy breast reconstruction is common abroad, corresponding research has been carried out in our country, experiences in learning are shairing. With deepening of domestic and foreign exchanges and progressing of technology, it is believed that post-mastectomy breast reconstruction might become one of conventional reconstruction options in future.
ObjectiveTo explore the application value of prognostic nutritional index (PNI) in the postoperative complications of McKeown surgery for da Vinci robotic esophageal cancer. MethodsThe clinical data of the patients who underwent da Vinci robotic McKeown surgery for esophageal cancer in the Department of Thoracic Surgery of the First Hospital of Lanzhou University from January 2019 to June 2022 were retrospectively collected. According to the receiver operating characteristic (ROC) curve, the optimal cut-off value of PNI for predicting postoperative complications was explored. The patients were divided into a high PNI group and a low PNI group according to the cut-off value, and the differences in basic characteristics, surgery-related indexes and postoperative complications between the two groups were analyzed. According to the occurrence of postoperative complications, the patients were divided into a non-complication group and a complication group. Univariate and multivariate analyses were used to explore the influence of relevant indicators on the occurrence of postoperative complications in da Vinci robotic McKeown surgery for esophageal cancer. ResultsFinally 120 patients were collected, including 95 males and 25 females, with an average age of 62.82 years. The preoperative hemoglobin content, preoperative blood lymphocyte count, preoperative serum albumin and preoperative blood total cholesterol in the high PNI group were higher than those in the low PNI group (P<0.05). There were statistical differences between the two groups in the incidences of postoperative overall complications, pulmonary infection, pleural effusion and poor incision healing (P<0.05). The relevant indicators that may cause postoperative complications were included in univariate analysis, and the results showed that age, operation time, intraoperative blood loss, preoperative blood lymphocyte count, preoperative hemoglobin content, preoperative blood mononuclear cell count, preoperative blood monocyte count, serum albumin level and PNI were possible influencing factors of postoperative complications after da Vinci robotic McKeown surgery for esophageal cancer. Incorporating these influencing factors into multivariate analysis, the results showed that age, PNI, operation time and intraoperative blood loss were independent influencing factors of postoperative complications. ConclusionPNI has certain predictive value in the postoperative complications of da Vinci robotic McKeown surgery for esophageal cancer. PNI is an independent factor affecting postoperative complications. Improving the level of PNI in esophageal cancer patient before surgery may help reduce the occurrence of postoperative complications.
Objective To summarize and analyze the application value of triple stomach shaping technique in laparoscopic sleeve gastrectomy (LSG). Methods The clinical data of patients undergoing simple LSG with triple stomach shaping technique carried out by the General Surgery Obesity and Metabolic Diseases Center of Chengdu Third People’s Hospital from January to December 2021 were retrospectively collected, recording the operative time and the occurrence of recent complications such as postoperative nausea/vomiting, gastric leakage, bleeding, obstruction/torsion within 30 days after operation. Results A total of 966 patients were collected, including 294 males and 672 females. The age was 16–65 years, average age was (32.8±8.6) years. Body mass index was 27.5–47.2 kg/m2, average was (34.2±3.5) kg/m2. All operations were successfully completed without conversion to laparotomy. The operative time was 45–170 min, average was (100.2+33.4) minutes. Postoperative nausea/vomiting occurred in 484 cases (50.10%), bleeding in 2 cases (0.21%, intraperitoneal bleeding in 1 case, intragastric bleeding in 1 case), gastric leakage in 1 case (0.10%, grade B leakage), and no perioperative death occurred. Hospitalization time was 4–24 d, average was (7.55±2.47) d. Two patients (0.21%) were hospitalized again due to nausea and vomiting within 30 days after operation, they were relieved and discharged after conservative medical treatment. Conclusion Triple gastric shaping technology is more physiological, safe and suitable for promotion.
ObjectiveTo provide clinical reference for the perioperative management of esophageal cancer patients with different stages of chronic obstructive pulmonary disease (COPD) through investigating the impact of COPD on postoperative complications and survival in esophageal cancer patients undergoing oesophagectomy.MethodsThe clinical data of 163 patients who underwent radical resection of esophageal cancer in our department from January 2015 to January 2018 were retrospectively analyzed, including 124 males and 39 females, with a median age of 64 years (IQR: 23.8 years). They were divided into a COPD group (n=87) and a non-COPD group (n=76) according to the presence of COPD before operation. The clinical data were collected and the postoperative complications and 2-year survival between the two groups were compared and analyzed.ResultsThe incidence of major postoperative complications (pulmonary infection, respiratory failure, arrhythmia and anastomotic leakage) in the COPD group were higher than those in the non-COPD group (all P<0.05). Spearman correlation analysis showed that the severity of preoperative COPD was positively correlated with the incidence of postoperative complications in patients with esophageal cancer (r=0.437, P<0.001). The incidence of postoperative respiratory failure and mortality in patients with severe COPD were significantly higher than those in patients without COPD and those with mild or moderate COPD. The 2-year survival rate of patients with esophageal cancer in the COPD group was lower than that in the non-COPD group (56.1% vs. 78.5.%, P=0.001), and the severity of COPD was negatively correlated to the survival rate.ConclusionCOPD significantly increases the incidence of postoperative complications in patients with esophageal cancer, which is not conducive to the prognosis of patients, and the severity of COPD is correlated with postoperative complications and 2-year survival rate.
ObjectiveTo compare the postoperative enhanced recovery outcomes of lobectomy performed under non-intubated video-assisted thoracic surgery (NIVATS) versus intubated video-assisted thoracic surgery (IVATS). Methods Computerized searches were performed in the following databases: China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP Information, China Biomedical Literature Database (CBMdisc), Web of Science, Clinicaltrials.gov, The Cochrane Library, EMbase, and PubMed. We collected randomized controlled trials (RCTs) and observational studies comparing NIVATS and IVATS. The search period extended from the inception of each database to April 1, 2023. Two independent researchers screened the literature and assessed study quality. ResultsA total of 14 studies were included, comprising 4 RCTs, 7 retrospective cohort studies, and 3 propensity score matching studies, involving 1 840 patients. Meta-analysis results indicated that, compared to IVATS, NIVATS was associated with significantly shorter operative time [MD=–13.39, 95%CI (–20.16, –6.62), P<0.001], shorter length of hospital stay [MD=–0.81, 95%CI (–1.39, –0.22), P=0.005], shorter chest tube duration [MD=–0.73, 95%CI (–1.36, –0.10), P=0.02], shorter postoperative anesthesia recovery time [MD=–20.34, 95%CI (–26.83, –13.84), P<0.001], and shorter time to oral intake after surgery [MD=–5.68, 95%CI (–7.63, –3.73), P<0.001]. Furthermore, NIVATS showed a lower incidence of postoperative airway complications [OR=0.49, 95%CI (0.34, 0.71), P<0.001] and less total chest tube drainage volume [MD=–251.11, 95%CI (–398.25, –103.98), P<0.001], all contributing to significantly accelerated postoperative enhanced recovery for patients. Conclusion NIVATS is a safe and technically feasible anesthesia method in thoracoscopic lobectomy, which can to some extent replace IVATS.
ObjectiveTo compare the outcomes of laparoscopic appendectomy (LA) and open appendectomy (OA) for the acute appendicitis patients based on our extensive experiences. MethodsThe data of all the acute appendicitis patients who underwent appendectomy from January 2013 to December 2014 in our department were retrospectively reviewed. A total of 201 patients were enrolled and divided into LA group (n=102) and OA group (n=99). The relevant clinical indexes during and after operation of two groups were compared. ResultsThere were no significant difference in age, gender, and underlying disease between LA and OA patients (P > 0.05). And the abdominal cavity infection rate, abdominal drainage rate and 30-day readmission rate were also similar (P > 0.05). But LA group had less operative time, lower infection operative wound rate, less intestinal function recovery time, shorter inhospital days and higher hospital expenses than OA group (P < 0. 05). In addition, perforated appendix and LA could increase the rate of abdominal drainage[OR=2.710, 95% CI(1.129, 6.507), P=0.026]. ConclusionsBoth LA and OA are safe and effective methods for the treatment of acute appendicitis. But LA has several advantages over OA on less operative time and postoperative complications, earlier recovery, and shorter inhospital days. While LA have higher hospital cost than OA, it still should be considered as a prefer way to cure acute appendicitis. LA is a independent risk factor of abdominal drainage.
Objective To evaluate the clinical effectiveness and safety of different mesh fixation techniques in laparoscopic trans-abdominal preperitoneal hernia repair (TAPP) by using network meta-analysis. Methods CNKI, WanFang Data, VIP, CBM, the Cochrane Library, PubMed, Embase, and Web of Science databases were retrieved to collect randomized controlled trials (RCTs) studies comparing different fixation methods of patches in laparoscopic TAPP. The retrieval time limit was from the establishment of the database to March 1, 2022. After two researchers independently screened the literatures, extracted the data, and evaluated the bias risk, Bayesian network meta-analysis was conducted by using R4.1.2 software. Results Twenty-nine RCTs were included, including 4 095 patients. The results of network meta-analysis showed that the risk of chronic postoperative inguinal pain was higher in staples fixation than that of no fixation [OR=0.06, 95%CI (0.01, 0.26), P＜0.001], glue fixation [OR=0.21, 95%CI (0.04, 0.53), P=0.001] and self-gripping mesh [OR=0.09, 95%CI (0.01, 0.52), P=0.009], the incidence of chronic postoperative inguinal pain with suture fixation was higher than that with no fixation [OR=0.10, 95%CI (0.01, 0.70), P= 0.020]. Postoperative visual analogue scale of staples fixation was higher than those of no fixation [MD=–0.90, 95%CI (–1.49, –0.33), P=0.002] and glue fixation [MD=–0.92, 95%CI (–1.35, –0.49), P＜0.001], the postoperative visual analogue scale with suture fixation was higher than those of no fixation [MD=–0.83, 95%CI (–1.61, –0.08), P=0.030] and glue fixation [MD=–0.85, 95%CI (–1.56, –0.13), P=0.020]. There was no significant difference in the incidence of seroma and hematoma, hospital stay and hernia recurrence among different fixation methods. Conclusions The network meta-analysis shows that medical glue and self-gripping mesh have certain advantages in reducing chronic pain after surgery, which may be the better patch fixation method in TAPP. The non fixation mesh will not increase the risk of postoperative recurrence, and can be used in clinical practice. This conclusion needs to be further verified by large sample, long-term follow-up and high-quality RCTs.
Objective To investigate the clinical characteristics and risk factors for perioperative lung surgery patients with SARS‐CoV‐2 Omicron variant infection. Methods The clinical data of patients who underwent lung surgery at the Department of Thoracic Surgery, Renmin Hospital of Wuhan University from December 1, 2022 to January 9, 2023 were retrospectively analyzed. The patients were divided into an infection group and a non-infection group according to whether they were infected with SARS-CoV-2. And the clinical data of two groups were collected and compared. Multiple linear regression analysis was used to explore the risk factors affecting the time of hospitalization. Results A total of 70 patients were enrolled in this study, including 36 (51.4%) males and 34 (48.6%) females at a median age of 61.0 (49.0, 66.8) years. There were 28 patients in the infection group and 42 patients in the non-infection group. The proportion of preoperative abnormal coagulation function and the risk of postoperative pulmonary infection in perioperative patients infected with SARS-CoV-2 were higher than those in the non-infection group (P<0.05). Subgroup analysis found that patients with preoperative SARS-CoV-2 infection were more likely to have pulmonary infection after surgery, but did not prolong the time of hospitalization or increase the risk of severe disease rate. The patients with postoperative SARS-CoV-2 infection had worse clinical prognosis, including longer time of hospitalization (P=0.004), higher ICU admission rate (P=0.000), higher lung infection rate (P=0.003) and respiratory failure rate (P=0.000). Multiple linear regression analysis showed that gender and extent of surgery were independent risk factors for prolonged hospitalization time. Conclusion Preoperative infection with SARS-CoV-2 Omicron variant will increase the risk of pulmonary infection, but it will not affect the clinical prognosis. However, postoperative infection with SARS-CoV-2 Omicron variant will still prolong the time of hospitalization, increase the ICU rate, and the risk of pulmonary complications.
ObjectiveTo investigate the clinical value of the C-reactive protein (CRP) ratio (CRP value on postoperative day 3/day 1) as an early predictor of postoperative severe complication after laparoscopic gastrectomy (LG) for gastric cancer.MethodsThis retrospective study examined the relationship between the occurrence of severe complication and the CRP ratio of 259 gastric cancer patients, who underwent LG in the Department of General Surgery of General Hospital of Fuxin Mining Industry Group of Liaoning Health Industry Group from January 2015 to January 2020. According to Clavien-Dindo (CD) grading system, gastric cancer patients were divided into the severe postoperative complication group (n=41, 15.8%) and the non-severe postoperative complication group (n=218, 84.2%). The relationship between CRP ratio and clinicopathologic characteristics of patients and the predictive value of CRP ratio for severe complication were analyzed.ResultsThe optimal cutoff value of CRP ratio of 2.2 offered 63.2% sensitivity, 91.0% specificity, 70.7% positive predictive value, and 85.8% negative predictive value for severe postoperative complication. The area under the receiver operating characteristic curve was 0.766. There had distinct differences (P<0.05) on body mass index, preoperative comorbidity, type of surgery, T stage, and TNM stage between the high CRP ratio group (CRP ratio >2.2, n=60) and the low CRP ratio group (CRP ratio ≤2.2, n=199). Logistic regression showed that preoperative comorbidity [OR=3.624, 95%CI (1.191, 11.206), P=0.023], later of TNM stage [OR=9.037, 95% CI (1.729, 47.226), P=0.009], and CRP ratio >2.2 [OR=20.473, 95%CI (7.948, 52.737), P<0.001] were independent risk factors for postoperative severe complication after LG.ConclusionThere must to be paid enough attention to the CRP ratio >2.2 on the day 1 and 3 after LG, it suggests that there might be a risk of severe postoperative complications.
