A Comparative Study of Intralobar Sequestration and Extralobar Pulmonary Sequestration

Abstract Objective: This study aims to identify the difference between patients who have been diagnosed with either intralobar sequestration (ILS) or extralobar sequestration (ELS).Methods: In this clinical study, 29 children with pulmonary sequestration (PS), diagnosed via physical examination and imaging at our hospital between January 2019 and January 2020, were enrolled. We compared whether statistical differences existed in the blood loss, operative time, and post-operative hospital stay between the two groups (ILS and ELS) after thoracoscopic pulmonary wedge resection.Results: There were no significant differences in gender, operative age, preoperative weight, and isolated lung position between the ILS and ELS groups (p > 0.05). There was significantly more intra-operative bleeding in children with ILS than those with ELS (p < 0.05), and the operation time and postoperative hospitalization times were significantly longer for those with ILS(p < 0.05). Upon microscopic evaluation after surgery, we found the appearance of ILS and ELS to be similar.Conclusion: Different types of congenital PS have different influences onnewborns during and after operation. For children with ILS, surgery is more difficult and the postoperative recovery is slower than for children with ELS. For this reason, we suggest that more attention should be paid to the clinical treatment of children with ILS. Although ILS and ELS present with different manifestations, we found no evidence of a significant difference in the postoperative microscopy of the two conditions.

AbstractThird space robotic and endoscopic cooperative surgery (TS-RECS) is a novel minimally invasive surgery for resecting gastric submucosal tumours (GSMTs), which could accomplish the completely oncological curability and maximal functional preservation. This study investigated the clinical outcomes and gastrointestinal function after TS-RECS versus laparoscopic wedge resection (LWR) for GSMTs. This was a single-centre retrospective study that included 130 patients with GSMTs who underwent LWR or TS-RECS from 2013 to 2019. To overcome selection biases, we performed propensity score matching (1:1) using seven covariates that could impact the group assignment and outcomes. Then, the clinical outcomes and gastrointestinal function in the LWR and TS-RECS groups were compared in a matched cohort. Among the 130 enrolled patients, 96 patients underwent LWR, and 34 underwent TS-RECS and were matched into 30 patients for each group. There was no significant difference in the operation time between the two groups (P = 0.543). However, the TS-RECS group had significantly less blood loss (20,5–100 vs 95,10–310 ml, P < 0.0001) and better postoperative recovery in terms of time to oral intake (2,2–4 vs 3,2–6 days, P < 0.0001) and postoperative hospital stay (5,4–10 vs 8.5,5–16 days, P < 0.0001) than the LWR group. The severity and frequency scores of postoperative gastrointestinal symptoms in the TS-RECS group were significantly lower than those in the LWR group. The median follow-up period was 24 months (10–60 months) in the LWR group and 18 months (10–27 months) in the TS-RECS group, and there was in total a single recurrence in the LWR group. TS-RECS appears to be a technically safe and effective surgery with preservation of gastrointestinal function for resection of GSMT resection.

Objectives: There is not yet a consensus on the optimal surgical technique for cesarean section. This is the first study comparing two different (Cesarean Section) with respect to the following inflammatory reaction in means of changes in inflammatory marker levels. To evaluate the differences in inflammatory reactions following two different (Cesarean Section) techniques, the modified Misgav-Ladach versus the Pfannenstiel-Kerr technique.Study Desıgn: The study population included 88 pregnant women who met the inclusion criteria. These women were randomized into two groups according to Consolidated Standards of Reporting Trials guidelines: Group 1 (Misgav-Ladach group) and Group 2 (Pfannenstiel Kerr group). To compare the inflammatory reactions following surgery, Interleukin-6 (IL-6) and Tumor Necrosis Factor-α (TNF-α) levels were measured in venous blood samples drawn from the patients just before (0 hour) and 24 hours (24th hour) after the surgery. In 5 women from Group 1 and 2 women from Group 2, the 24th hour blood samples could not be obtained or were lost. Thus, a total of 81 women, 39 women from Group 1 and 42 women from Group 2, comprised the population of study. The differences in inflammatory reactions between the 0 and 24th hours were analyzed by calculating the percent change in IL-6 and TNF-α levels, and these percentages were then compared between the groups.Results: There was a statistically significant difference between Group 1 and Group 2 regarding the serum IL-6 level change between 0 and 24th hour (530±653% and 196±168%, respectively, p=0.022. The difference in TNF-α was also higher in Group 2, but the difference was not statistically significant (229±306% vs. 571±824%, p=0.12). The mean operation time was significantly shorter in Group 1 (9.44 min. vs. 16.86 min, p=0.0001).Conclusions: The results of this study indicate that the modified Misgav-Ladach technique has a weaker inflammatory reaction, which indicates fewer short- and long-term surgical complications.

Die Bonding

In the integrated circuit (IC) packaging process, including operations of die sawing, die bonding, wire bonding, molding, plating, marking, trim/form, and inspection. Purposes of packaging include protecting ICs, making ICs easier to handle, and connecting ICs to the circuit outside. The wire bond stations are the bottleneck in the packaging and assemble process where the heat block is the key auxiliary parts in the stations. This research proposes a RFID-enabled Heat Block Management System (RHMS) to accurately control the progress of the IC packaging production line to meet the customer requirements. Our research analyzed all the flows of heat block management operations during before and after introducing RHMS. Hypothesis testing can verify significant difference between two sample sizes. Based on the statistics test of hypothesis, we compared the difference for before and after introducing RHMS. The results show that the RHMS can bring advantage for heat block management in wire bond stations. Moreover, it has clear improvement of saving counting and revising operation time. The contributions of this research are not only a case study but also a direction for applying RFID technology on IC packaging industry.

Abstract Objective To compare perioperative and oncologic outcomes of open modified ureterosigmoidostomy urinary diversion (OMUUD) and intracorporeal modified ureterosigmoidostomy urinary diversion (IMUUD) following laparoscopic radical cystectomy (LRC). Patients and methods We retrospectively reviewed our single institutional collected database patients undergoing LRC from October 2011 to October 2019. The perioperative characteristics were compared between OMUUD and IMUUD, and overall survival (OS) and progression-free survival (PFS) were evaluated by the Kaplan-Meier method. Results Overall, 84 patients were included. OMUUD and IMUUD were performed in 63 (75%) and 21 (25%) patients, respectively. IMUUD patients demonstrated shorter postoperative length of stay (16.24 ± 3.91 days vs. 18.98 ± 7.41 days, P = 0.033), similar operation time (498.57 ± 121.44 vs. 462.24 ± 99.71, P = 0.175), similar estimated blood loss [400 (200–475) ml vs. 400 (200–700) ml, P = 0.095], and similar overall complication rate within 30 days (19.05% vs. 25.40%, P = 0.848) and 90 days (23.81% vs. 17.46%, P = 0.748). Complete urinary control rate was 87.3% (55/63) in the OMUUD group. In IMUUD, the complete urinary control rate was 90.5% (19/21). There was no significant difference in OS (χ2 = 0.015, P = 0.901) and PFS (χ2 = 0.107, P = 0.743) between the two groups. Conclusion IMUUD postoperative recovery is faster; other perioperative outcomes and oncology results are not significantly different with OMUUD. It is indicated that IMUUD can be utilized safely and effectively in the urinary diversion after LRC.

Objective. To develop a new type infusion set and apply it to the clinic, as well as explore its effectiveness in the prevention from needle stick injuries. Methods. A total of 200 inpatients who were in need of intravenous infusion with a disposable infusion needle were included and randomly divided into two groups: intervention group and control group. Disposable infusion needles with a separation-free safety tube were used in the intervention group, whereas conventional ones were used in the control group. Then, effects of the two types of infusion sets were observed and compared. Results. As for the operation time for infusion, it was (82.19±1.80) seconds in the intervention group and (83.02±1.83) seconds in the control group, with the difference statistically significant (P<0.05). Besides, the exposure time of the needles after infusion in the intervention group was (3.36±0.17) seconds while (18.85±1.18) seconds in the control group; the difference between which was statistically significant (P<0.05). In terms of the time for needle disposal, (18.60±0.84) seconds was required in the intervention group, while for the control group, it took (18.85±1.18) seconds, and the difference between two groups was of statistical significance as well (P<0.05). Nevertheless, there was no statistically significant difference in the accidental slip rate of the needles as that turned out 0% in both groups (P>0.05). It was worth noting that the block rate of the disposed needles in the intervention group was 100%. Conclusion. The separation-free safety tube on the disposable infusion needle could instantly block the sharp needle after infusion, which reduces the needle exposure time and lowers the risk of needle stick injuries. In the meantime, the safety tube is convenient to use, and its application can shorten the time for infusion and needle disposal, consequently improving the working efficiency of nurses. As the new type safety tube has above advantages and would not raise the risk of needle slippage, it is worthy of clinical promotion.

Background. The ability to perform reliable, secure endoluminal closure of the gastrointestinal tract wall, is a prerequisite to support the progress of the emerging field of endoluminal surgery. Along with advanced clipping systems, flexible endoscopic suturing devices are commercially available. Current systems can replicate traditional surgical suturing patterns in the endoluminal environment. The aim of this study was to evaluate the optimal endoluminal suturing technique using a flexible endoscopic suturing device. Materials and Methods. Procedures were performed on bench-top simulators containing 20 explanted porcine stomachs. A standardized 3-cm full-thickness incision was created on the anterior wall of each stomach using monopolar cautery. The gastrotomy was closed endoscopically using an over-the-scope suturing device (OverStitch, Apollo Endosurgery; Austin, TX). Three different techniques were used: single stitches, figure-of-8 pattern, and running suture. Material consumption and operation time were recorded and bursting pressure measurement of the closure was performed. Results. No statistically significant differences were identified in suturing time. Suturing time (minutes) was slightly shorter with the figure-of-8 technique (41.14 ± 4.6) versus interrupted (45.75 ± 1.1) versus continuous (51.44 ± 10.0), but the difference was not statistically significant. The number of sutures required was greater in the interrupted group. No significant difference was found in the burst pressure (mm Hg): figure-of-8 (45.85 ± 26.2) versus interrupted (30.5 ± 22.89) versus continuous (32.0 ± 26.5). In the figure-of-8 group, 85.5% of cases were leakproof above 30 mm Hg, while in the other groups only 50% of cases were so. Conclusion. A figure-of-8 suturing pattern seems to be the preferable suturing technique with the endoscopic suturing device.

Pulmonary Wedge Resection

This study was aimed at studying the pulmonary nodule (PN) classification and diagnosis through computed tomography (CT) images based on segmentation algorithms. 120 PN patients were taken as research subjects. Linear filter fine segmentation algorithm under 3D region growth was compared with the initial segmentation algorithm and applied to images of PN patients. The results showed that the segmentation effect of the proposed algorithm was at the upper-middle level. The cases of patients with smoking history were greatly more than those without (χ2 = 1.256, P < 0.05 ). Benign and malignant PNs were classified, and morphological features included rough ones and round-like ones. The size characteristics included edge length and area. The gray-scale features included the uniformity of the gray-scale value and the mean value of the gray-scale value. The operation time of pulmonary lobectomy (76.2 ± 23.1 min) was obviously longer than that of pulmonary wedge resection (27.5.2 ± 4.5 min) ( P < 0.05 ). The surgical blood loss of patients who underwent pulmonary lobectomy (125 ± 42 mL) was remarkably higher versus patients who underwent pulmonary wedge resection (51.6 ± 13.8 mL) ( P < 0.05 ). After the operation, the length of stay of patients who underwent lobectomy (8.6 ± 1.4 days) was evidently longer than that of patients who underwent wedge resection (6.4 ± 1.2 days) ( P < 0.05 ). The classification of benign and malignant PNs can effectively obtain the shape and size characteristics of PNs. Preoperative positioning surgery based on classification can shorten the operation time, reduce the amount of bleeding during the operation, and help improve the success rate of surgical resection.

Background: This study aims to compare robot-assisted lobectomy versus completely portal robotic lobectomy. Methods: Between January 2014 and December 2019, a total of 41 patients (10 males, 31 females; median age 62 years; range, 50 to 68 years) underwent robotic anatomical pulmonary resection in our institution were retrospectively analyzed. The patients were consecutively divided into two groups: the first 20 (48.8%) patients underwent pulmonary resection by robot-assisted lobectomy technique, while the next 21 (51.2%) patients underwent pulmonary resection by completely portal robotic lobectomy with four arms. Data including age, sex, diagnosis, surgery type and duration, rate of conversion to open surgery, and length of stay of the patients were recorded. The operation time, docking time, console time, and closure duration for each patient were also noted. Results: There was no statistically significant difference in age, sex, comorbidities, complications, length of hospital stay, adequate lymph node staging, or tumor size and side between the two groups (p>0.05). However, the mean console and operation times were statistically significantly shorter in the patients receiving completely portal robotic lobectomy with four arms (p=0.001). Conclusion: The advantage of completely portal robotic lobectomy with four arms is relative, although it significantly shortens the operation time. Based on our experiences, this technique may be preferred in case of inadequate lung deflation, as carbon dioxide insufflation allows sufficient workspace for robotic lung resection.

Abstract BackgroundThe prevalence of and potential risk factors for postoperative cough after thyroidectomy remain unknown. The current study aimed to analyze postoperative cough in patients undergoing thyroidectomy using a prospective analysis.MethodsAdult patients undergoing primary thyroidectomy were prospectively enrolled. Data regarding age, sex, BMI, pathology and surgical procedure were collected and analyzed. All patients were asked to complete the Leicester Cough Questionnaire (LCQ) preoperatively and at 2 weeks and 4 weeks postoperatively.ResultsThere were 1264 patients enrolled in total. Eleven patients with vocal cord paralysis were excluded. In patients with benign disease, postoperative cough occurred in 61 patients, with an prevalence rate of 17. 0% compared to an prevalence rate of 33.1% in patients with malignant disease; the difference was significant. For benign patients, the factors of smoking and operation time were independently related to the occurrence of postoperative cough. For malignant patients, the factors of smoking, operation time, operation extent, and the number of positive nodes at level 6 were independently related to the occurrence of postoperative cough. There was no significant difference regarding the LCQ score in patients with benign or malignant disease at the preoperative and the postoperative 4-week time periods. Patients with malignant disease had a significantly lower LCQ score than patients with benign disease at the postoperative 2-week time point (p=0.004).ConclusionsPatients undergoing thyroid cancer surgery had a higher prevalence of postoperative cough and were also associated with a decreased cough-related quality of life. The factors of smoking and operation time were the most important predictors for postoperative cough after thyroidectomy.

Abstract Objectives: To evaluate the feasibility and advantages of wedge resection plus transverse suture applied to loop ileostomy closure by analyzing the surgical data and the incidence of postoperative complications of patients undergoing this procedure.Methods: We performed a retrospective analysis of the hospitalization data of patients who underwent ileostomy closure surgery and met the research standards from January 2017 to April 2021 in the Guangxi Medical University Cancer Hospital; all surgeries were performed by the same surgeon. The perioperative data were statistically analyzed by grouping.Results: In total, 65 patients were enrolled in this study, with 12 in the wedge resection group, 35 in the stapler group, and 18 in the hand suture group. There was no significant difference in operation time between the wedge resection group and stapler group (P > 0.05), but both groups had shorter operation time than that in the hand suture group (P< 0.05). The postoperative exhaustion time of wedge resection group was earlier than that of the others, and cost of surgical consumables in the wedge resection group was significantly lower than that in the stapler group, all with statistically significant differences (P< 0.05). By contrast, there was no statistically significant difference in postoperative complication incidences among the three groups.Conclusions: The wedge resection plus transverse suture is safe and easy for closure of loop ileostomy, and the intestinal motility recovers rapidly postoperatively. It has less surgical consumables, and is particularly suitable for the currently implemented Diagnosis-Related Groups payment method.
