Outcomes of subsequent abdominal operations after an initial ventral hernia repair.

INTRODUCTION: Nearly 20% of ventral hernia repair (VHR) patients require a subsequent abdominal operation (SAO), and mesh position may impact the complexity and outcome of the SAO. METHODS: Retrospective review of VHR with mesh from 2006 to 2020 from an internal database and the ACHQC. Primary outcomes measured incidence, complexity, and complications of SAO relative to mesh position. RESULTS: SAO was required in 433 of 2539 (17.1%) patients, totaling 671 operations; 197/893 (22.1%) with intraperitoneal mesh (IPM) and 236/1646 (14.3%) with extraperitoneal mesh (EPM; p â€‹< â€‹0.001). SAO was directly related to VHR in 180 (232 total SAOs) and unrelated in 253 (439 total SAOs). There were no significant differences in complications after SAO between IPM and EPM, nor any difference in adhesion complexity. CONCLUSION: Incidence of SAO is higher with IPM, but surgical outcomes are similar. Due to the risk of secondary mesh infection with IPM, significantly more of these were removed at the time of SAO.

The Efficacy of Probiotics, Prebiotics, and Synbiotics in Patients Who Have Undergone Abdominal Operation, in Terms of Bowel Function Post-Operatively: A Network Meta-Analysis.

BACKGROUND: Abdominal operations may lead to post-operative bowel dysfunction, while administration of probiotics, prebiotics and synbiotics may limit its manifestation. Τhe study aimed to assess the efficacy of probiotics, prebiotics and synbiotics in patients who undergone abdominal operation, in terms of bowel function post-operatively. METHODS: PubMed, Scopus, Cochrane Central Register of Controlled Trials (Central), Embase, US Registry of clinical trials, and sources of grey literature were searched. The relative effect sizes were estimated, and we obtained the relative ranking of the interventions using cumulative ranking curves. RESULTS: In total, 30 studies were included in the analysis. For the outcome of post-operative ileus, probiotics was superior to placebo/no intervention (relative risk, RR: 0.38; 95%CI: 0.14-0.98) with the highest SUCRA (surface under the cumulative ranking) value (92.1%). For time to first flatus, probiotics (MD: -0.47; 95%CI: -0.78 to -0.17) and synbiotics (MD: -0.53; 95%CI: -0.96 to -0.09) were superior to placebo/no intervention. For time to first defecation and for post-operative abdominal distension probiotics were superior to placebo/no intervention. For post-operative hospitalization days, synbiotics were superior to placebo/no intervention (MD: -3.07; 95%CI: -4.80 to -1.34). CONCLUSIONS: Administration of probiotics in patients who had undergone abdominal surgery reduced the prevalence of post-operative ileus, time to first flatus, time to first defecation, and prevalence of post-operative abdominal distension. Synbiotics reduce time to first flatus and post-operative hospitalization days.

Patients with gastroenteric tumor after upper abdominal surgery were more likely to require rescue analgesia than lower abdominal surgery.

OBJECTIVES: To find out the reasons why patients still need to use rescue analgesics frequently after gastrointestinal tumor surgery under the patient-controlled intravenous analgesia (IV-PCA), and the different abdominal surgery patients using the difference of analgesics. METHODS: A total of 970 patients underwent abdominal operation for gastrointestinal tumors were included. According whether patients used dezocine frequently for rescue analgesics within 2 days after surgery, they assigned into two groups: RAN group (Patients who did not frequently use rescue analgesia, 406 cases) and RAY group (Patients who frequently used rescue analgesia, 564 cases). The data collected included patient's characteristics, postoperative visual analogue scale (VAS), nausea and vomiting (PONV), and postoperative activity recovery time. RESULTS: No differences were observed in the baseline characteristics. Compared with the RAN group, patients in the RAY group had a higher proportion of open surgery, upper abdominal surgery, VAS score at rest on the first 2 days after surgery and PONV, and a slower recovery of most postoperative activities. Under the current use of IV-PCA background, the proportion of rescue analgesics used by patients undergoing laparotomy and upper abdominal surgery was as high as 64.33% and 72.8%, respectively. Regression analysis showed that open surgery (vs laparoscopic surgery: OR: 2.288, 95% CI: 1.650-3.172) and the location of the tumor in the upper abdomen (vs lower abdominal tumor: OR: 2.738, 95% CI: 2.034-3.686) were influential factors for frequent salvage administration. CONCLUSIONS: In our patient population, with our IV-PCA prescription for postoperative pain control, patient who underwent open upper abdominal surgery required more rescue postoperative analgesia.

Effect of anesthesia at different depths on postoperative cognitive disfunction and inflammatory response in the elderly patients undergoing abdominal operation / 新乡医学院学报

Objective To investigate the effect of anesthesia at different depths on postoperative cognitive disfunction (POCD) and inflammatory response in the elderly patients undergoing abdominal operation.Methods A total of 90 elderly patients who underwent abdominal operation in the Affiliated Hospital of Shaanxi University of Chinese Medicine from June 2014 to June 2016 were divided into observation group and control group according to the depth of anesthesia,45 cases in each group.The patients in the two groups were performed with combined intravenous and inhalation anesthesia,the bispeetral index (BIS) value was maintained at 30-39 during the operation in the observation group,and the BIS value was maintained at 50-59 during the operation in the control group.The mean arterial pressure (MAP) and heart rate(HR) of patients in the two groups were recorded at the time points of entering the operation room(T0),5 minutes after tracheal cannula(T1),opening abdominal cavity (T2),closing abdominal cavity (T3) and tracheal cannula extubation (T4).The mini-mental state examination (MMSE) score of the patients in the two groups was performed before operation and the first,third,seventh day after operation;and the incidence of POCD was recorded.The levels of serum interleukin-6(IL-6) and S-100β protein were detected at the time points of before operation,the end of the operation and the first,third day after operation in the two groups.Results Five cases in the control group and six cases in the observation group were eliminated,39 cases in the observation group and 40 cases in the control group were evaluated finally.The MAP at T1 and T2 was significantly lower than that at T0 in the two groups (P ＜ 0.05).There was no significant difference in the MAP between T3,T4 and T0 in the two groups(P ＜ 0.05).There was no significant difference in the HR each time point in each group(P ＜ 0.05).There was no significant difference in the MAP and HR between the two groups at each time point(P ＜ 0.05).There was no significant difference in the MMSE score between the two groups before operation(P ＜ 0.05).The MMSE score of patients at the first and third day after operation was significantly lower than that before operation and the seventh day after operation in the two groups (P ＜ 0.05).There was no significant difference in the MMSE score between before operation and the seventh day after operation in the two groups(P ＜0.05).The MMSE score in the observation group was significantly higher than that in the control group at the first and third day after operation (P ＜ 0.05).There was no significant difference in the MMSE score between the two groups at the seventh day after opera tion(P ＜ 0.05).The incidences of POCD at the first,third and seventh day after operation in the observation group were 28.21％ (11/39),15.38％ (6/39) and 7.69％ (3/39) respectively;and they were 50.00％ (20/40),37.50％ (15/40) and 20.00％ (8/40) respectively in the control group.The incidence of POCD in the observation group was significantly lower than that in the control group at the first and third day after operation (x =3.934,4.949;P ＜ 0.05).There was no significant difference in the incidence of POCD between the two groups at the seventh day after operation(x2 =2.496,P ＜ 0.05).There was no significant difference in the levels of serum IL-6 and S-100β protein between the two groups before operation (P ＜0.05).The levels of serum IL-6 and S-100β protein at the end of operation and the first,third day after operation were significantly higher than those before operation in the two groups(P ＜ 0.05).The levels of serum IL-6 and S-100β protein in the observation group were significantly lower than those in the control group at the end of operation and the first,third day after operation (P ＜ 0.05).Conclusion Deep anesthesia (BIS value is maintained at 30-39) can reduce the levels of inflammatory factors,the incidence of POCD after operation and the brain damage in the elderly patients with abdominal operation.

Venous thromboembolism in common laparoscopic abdominal surgical operations.

BACKGROUND: Venous thromboembolism (VTE) is potentially a serious postoperative complication. We examined the incidence and outcome of VTE among different laparoscopic abdominal surgical operations for benign diseases. METHODS: The National Surgical Quality Improvement Program database was utilized to evaluate all patients with benign disease who underwent laparoscopic abdominal operations including colorectal surgery, bariatric surgery, cholecystectomy, esophageal surgery, abdominal wall hernia repair, and appendectomy from 2005 to 2014. Multivariate logistic regression analysis was performed. RESULTS: 750,159 patients were studied and the overall incidence of VTE was 0.32% within 30 days of operation. Colorectal surgery had the highest incidence of VTE (734/65512, 1.12%) with significantly longest length of stay and operative time. Patients who developed VTE had higher mortality and worse outcomes compared to non-VTE patients. CONCLUSIONS: Laparoscopic colorectal operations for benign disease is at higher risk for development of VTE compared to other laparoscopic abdominal operations. Further studies should be performed to elucidate the underlying mechanisms for our finding.

Intraoperative baseline oxygen consumption as a prognostic factor in emergency open abdominal surgery.

BACKGROUND: A new anesthesia system, the E-CAIOVX (GE Healthcare) enables the continuous monitoring of oxygen consumption (VO2) and carbon dioxide elimination (VCO2) during the surgical operation. The aim of this study was to evaluate the prognostic role of intraoperative baseline VO2 and VCO2 in an emergency open abdominal operation. METHODS: A total of 103 patients who had an emergency open abdominal operation were enrolled in the study. VO2 and VCO2 were continuously measured from the induction of anesthesia to the end of the operation. RESULTS: There were significant correlations between intraoperative baseline VO2 and body surface area (BSA; P < .001, r = 0.68), VO2 and tidal volume (P < .001, r = 0.59), and VO2 and baseline body temperature (P < .0001, r = 0.49). Also, there were significant correlations between intraoperative baseline VCO2 and BSA (P < .001, r = 0.70), VCO2 and tidal volume (P < .001, r = 0.70), and VCO2 and body temperature (P < .001, r = 0.41). Fifteen (14.6%) of the 103 patients died within 4 months after the operation without having been discharged from hospital. Baseline VO2/BSA was higher in surviving patients (123.7 ± 23.6 mL/min ∙ m(2)) than the deceased (103.8 ± 15.6 mL/min ∙ m(2); P = .002). There was no significant difference in baseline VCO2/BSA levels between surviving (106.2 ± 20.1 mL/min ∙ m(2)) and deceased patients (99.4 ± 21.4 mL/min ∙ m(2)). In multivariate analysis, baseline body temperature lower than 36.2°C (P = .02), serum albumin less than 3.0 g/dL (P = .002), and baseline VO2/BSA less than 111.9 mL/min ∙ m(2) (P = .03) were independent factors. CONCLUSION: Baseline low VO2/BSA less than 111.9 mL/min ∙ m(2) was one of the poor predictors for the prognosis of an emergency open abdominal surgery.

The results of the study can provide a reference for evaluating the nursing service quality of abdominal operation patients.

Clinical analysis of common abdominal operation complicated with pleural effusion / 国际外科学杂志

Pleural effusion is one of the common complications after abdominal surgery, which has a high incidence rate. It not only extends the length of hospital stay and increases the economic burden, but also may affect the prognosis of patients or even endanger lives. Therefore, early diagnosis and treatment of pleural effusion are important for postoperative rehabilitation. So far,the relationship between pleural effusion and clinical pathological factors of postoperation has not been revealed clearly and definitely. Preventive measures and the causes are summarized by reading a large number of literatures and combining with clinical experience to reduce incidence rate.

Factors Related to Postoperative Pulmonary Complication after Abdominal Operation: 193 Cases Report / 中国康复理论与实践

@#Objective To investigate the related factors of postoperative pulmonary complications with abdominal operation. Methods 193 cases after abdominal operation were reviewed. The age, smoking history, surgery duration, surgical site, pulmonary function, artery blood gas analysis, and the incidence of post-operative pulmonary complications were analyzed. Results Pulmonary complications were found in 29 cases. The age was higher and surgery duration was longer in patients with pulmonary complications than those without pulmonary complications (P<0.05). The patients with abnormal forced expiratory volume in the first second (FEV1)%, FEV1/ forced vital capacity (FVC)%, maximum ventilatory volume (MVV)% and smoking history before operation were in higher risk for post-operative pulmonary complications (P<0.05). There was significant difference in artery blood gas analysis between the 2 groups (P<0.05). Conclusion The age,smoking history, surgery duration and pulmonary dysfunction may be the risk factors of pulmonary complications after abdominal operation,while it is important to monitor the blood gas analysis.
