ABSTRACT
Objective:To analyze the effect of lung protective ventilation on lung ventilation function and serum Clara cell protein 16 (CC16) level in patients undergoing gynecological laparoscopic surgery.Methods:The clinical data of 80 gynecological patients who underwent laparoscopic surgery in Yancheng City Jianhu County People′s Hospital from October 2018 to December 2020 were randomly divided into group A and group B by random number table, each group with 40 cases. The patients in group A were treated with intermittent positive-pressure ventilation, and the patients in group B were ventilated with whole course ventilation mode. The pulmonary ventilation function, CC16 level and postoperative pulmonary complications were observed before anesthesia, 10 min of pneumoperitoneum, 30 min of pneumoperitoneum, 5 min of pneumoperitoneum stop and 2 h after operation. The patients were divided into groups according to whether with pulmonary complications, and their pulmonary ventilation function and serum CC16 level were compared. The predictive value of the above indexes for pulmonary complications was analyzed by receiver operating characteristic (ROC) curve.Results:Repeated measurement analysis of variance showed that alveolar arterial oxygen differential pressure (PA-aDO 2) were significant differences in time point factors, time point interaction factors and group factors ( P<0.05); CC16 index were significant differences in time point factor and group factor ( P<0.05). According to the observation from postoperative to discharge, 4 patients (10.0%) in group A had pulmonary complications, 15 cases (37.5%) had pulmonary complications in group B, the levels of PA-aDO 2 and CC16 in patients with complications were significantly higher than those in patients without complications: group A:(332.9 ± 2.0) mmHg (1 mmHg = 0.133 kPa) vs. (290.4 ± 13.2) mmHg, (53.5 ± 1.5) μg/L vs. (39.5 ± 6.5) μg/L; group B: (339.1 ± 8.8) mmHg vs. (305.7 ± 17.9) mmHg, (41.5 ± 4.2) μg/L vs. (39.7 ± 5.8) μg/L, there were statistical differences ( P<0.05). ROC curve analysis showed that the area under the curve(AUC) of PA-aDO 2 and CC16 in predicting pulmonary complications in group A were 0.882 and 0.833, in group B was 0.885 and 0.731. Conclusions:Lung protective ventilation has little effect on lung ventilation function and serum CC16 in patients with gynecological laparoscopic surgery, and the probability of pulmonary complications is lower. The pulmonary ventilation function and CC16 have certain value in predicting postoperative pulmonary complications.

ABSTRACT
Gastrointestinal stromal tumor (GIST) is a kind of mesenchymal tumor, most commonly found in the stomach, with unique immunophenotype and molecular genetic characteristics. Gastric GIST mostly originates from the musculi propria of the stomach wall. It often grows expansively with clear boundaries and is relatively easy to separate. Surgery is still the preferred treatment for gastric GIST. With the rapid development of laparoscopic technique, laparoscopic surgical treatment for gastric GIST has been gradually recognized. However, it still remains unclear whether laparoscopic surgery can be applied in gastric gastrointestinal stromal tumors located in unfavorable sites. Here, this paper will combine author center′s exploration and clinical application on laparoscopic surgery for gastric GIST located in unfavorable sites and make a brief summary in order to choose a better way for treatment of gastric GIST located in unfavorable sites.
ABSTRACT
Laparoscopy technology is widely used in urology. The mastery of laparoscopic surgery by urologists is very important to improve the quality of surgery and improve the prognosis of patients. However, there is no evaluation system for the maturity of laparoscopic technology of urologists. Based on this situation, in recent years, some evaluation criteria or evaluation elements have emerged to try to evaluate the laparoscopic skills of urologists. This article mainly summarizes the common evaluation tools, application scenarios, and limitations of laparoscopic technology in urology, and made an idea to establish a laparoscopic technology evaluation system in urology, providing a certain reference for the application and development of training and evaluation tools of laparoscopic technologyin urology.
ABSTRACT
Objective:Three-dimensional simulation modeling technology was used to conduct three-dimensional reconstruction, classification and measurement for the anatomic structures of colorectal canal, tumor and key blood vessels in patients with rectal cancer before operation. And the accuracy of the data and information obtained for the prediction of anastomotic tension, important types of vascular variant, positioning of anatomical landmarks, etc. in laparoscopic-assisted radical resection of rectal cancer, and the guiding effect of operation was evaluated.Methods:The clinical data of 50 patients with laparoscopic-assisted radical resection of rectal cancer treated in the General Surgery Department, Beijing Ditan Hospital Capital Medical University from January 2019 to February 2021 were analyzed retrospectively, including 31 males and 19 females, aged from 42 to 83 years old, with an average age of (62.72 ±15.21) years. The patients were divided into two groups according to whether the patients underwent three-dimensional simulation reconstruction before operation. The patients who underwent abdomen pelvic enhancement CT and further three-dimensional reconstruction before surgery were taken as reconstruction group ( n=24), and the patients who were only routinely performed abdomen pelvic enhancement CT before operation were taken as control group ( n=26). For the patients in the reconstruction group, the CT images were modeled by Mimics software before operation, and the key data such as the length of colorectal and tumor, the correlation length of rigid structure of pelvic wall, the length of inferior mesenteric artery (IMA) from the bifurcation point of left and right arteria iliaca communis, the type and proportion of IMA variation, the length of left colonic artery (LCA) from the beginning of IMA and the distance between LCA and IMV were measured, and the consistency correlation coefficient (CCC) was analyzed with the actual data obtained during operation. And then the accuracy of three-dimensional simulation modeling technology for surgical guidance was evaluated. MedCalc 19.0 software was used for statistical analysis. Results:In the reconstruction group, regarding the data of each dimension of the model (intestinal tract, pelvic cavity, blood vessels) and the corresponding structural measurements during the operation, the consistent correlation coefficient (CCC) evaluation was more than 0.9. One case was predicted to have free splenic flexure of colon and one case actually had free splenic flexure of colon. The prediction accuracy was 100%. The IMA variants in the reconstruction group were divided into 4 types, all of which were verified by operation. Compared with the control group, the operation time ( P=0.011) and the location time (IMA, P=0.043; LCA, P=0.007; IMV, P=0.034) of each vessel in the reconstruction group were shorter, and the amount of intraoperative blood loss was less ( P=0.017). Conclusion:The application of three-dimensional simulation modeling technology before operation is helpful for the operator to accurately predict the intraoperative anastomotic tension, the type of IMA variation and the related diameter length, based on which the accurate operation plan can be made to guide the operation.
ABSTRACT
Objective:To explore the effects of different doses of dexmedetomidine (DEX) on inflammatory factors and immune function in patients with gynecological malignant tumors who underwent laparoscopic surgery.Methods:A total of 60 patients with gynecological malignant tumors who underwent laparoscopic surgery from January 2021 to December 2021 in the Second Hospital of Shanxi Medical University were selected as the research objects. All patients were divided into the control group, low-dose DEX group (group D1) and high-dose DEX group (group D2) by using random number table method, 20 cases in each group. Patients in D1 and D2 groups were intravenously pumped DEX 0.5 μg/kg and 1.0 μg/kg 10 minutes before induction of anesthesia, and then maintained with DEX 0.5 μg·kg -1·h -1 and 1.0 μg·kg -1·h -1 until 30 minutes before the end of operation; and patients in the control group were given the same amount of Nacl solution. The 10 ml peripheral venous blood were collected at 10 minutes before induction of anesthesia (T 1), 1 h after pneumoperitoneum relief (T 2) and 24 h after pneumoperitoneum relief (T 3). The changes of interleukin-6 (IL-6), interleukin-10 (IL-10), the proportion of CD4 +, the proportion of CD8 + and CD4 +/CD8 + ratio of the three groups were compared, and the cases of bradycardia and hypotension in perioperative period and the time of first exhaust after operation were recorded. Results:At T 1,T 2 and T 3, the expression level of IL-6 in the control group was (7.95±0.26) pg/ml, (8.30±0.24) pg/ml and (8.35±0.28) pg/ml, respectively, and the difference was statistically significant ( F = 14.14, P < 0.001); the expression level of IL-10 in the control group was (38.9±2.6) pg/ml, (44.5±6.6) pg/ml and (46.3±4.6) pg/ml, respectively, and the difference was statistically significant ( F = 12.45, P < 0.001); the proportion of CD4 + in the control group was (38.5±2.1)%, (29.5±4.6)% and (29.6±3.5)%, respectively, and the difference was statistically significant ( F = 40.82, P < 0.001); the ratio of CD8 + in the control group was (30.1±3.7)%, (35.1±6.3)% and (40.3±8.2)%, respectively, and the difference was statistically significant ( F = 13.02, P < 0.001); the CD4 +/CD8 + ratio in the control group was 1.29±0.14, 0.84±0.09 and 0.75±0.14, respectively, and the difference was statistically significant ( F = 99.94, P < 0.001). The expression level of IL-6 in group D1 and group D2 was (8.10±0.32) pg/ml and (8.01±0.30) pg/ml at T 2, and (8.12±0.35) pg/ml and (8.05±0.34) pg/ml at T 3,which were lower than those in the control group, and the differences were statistically significant (all P < 0.05). The expression level of IL-10 in group D2 was (40.6±3.5) pg/ml at T 2, which was lower than that in the control group, and the difference was statistically significant ( P < 0.05). At T 3, the expression level of IL-10 in group D1 and group D2 was (43.7±3.5) pg/ml and (42.4±3.9) pg/ml, which were lower than those in the control group, and the differences were statistically significant (all P < 0.05). At T 2, the proportion of CD4 + in group D2 was (34.5±4.3)%, which was higher than that in the control group, and the difference was statistically significant ( P < 0.05). At T 3, the proportion of CD4 + in group D1 and group D2 was (32.1±4.2)% and (33.7±2.8)%, which were higher than those in the control group, and the differences were statistically significant (all P < 0.05). At T 2, the proportion of CD8 + in group D2 was (30.7±5.5)%, which was lower than that in the control group, and the difference was statistically significant ( P < 0.05). At T 3, the proportion of CD8 + in group D1 and group D2 was (35.4±5.8)% and (32.5±5.1)%, which were lower than those in the control group, and the differences were statistically significant (all P < 0.05). The CD4 +/CD8 + ratio in group D1 and D2 was 0.99±0.17 and 1.14±0.16 at T 2, 0.93±0.19 and 1.05±0.16 at T 3, which were higher than those in the control group, and the differences were statistically significant (all P < 0.05). Meanwhile, 1 case of hypotension occurred in the the control group and group D1, respectively; 3 cases of bradycardia and 2 cases of hypotension occurred in the group D2. The time of exhaust in the control group was later than that in group D1 and D2, and the difference was statistically significant ( P < 0.05). Conclusions:DEX can inhibit the inflammatory reaction during laparoscopic surgery in patients with gynecological malignant tumors, reduce immune damage. The anti-inflammatory action and immune protection of high-dose of DEX is more significant compared with low-dose of DEX, while high dose of DEX is more likely to cause hemodynamic fluctuations in perioperative period.
ABSTRACT
Objective:To explore the clinical application value of preoperative colonoscopic marking by Nd-Fe-B magnet ring to assist laparoscopy.Methods:A total of 51 patients with colorectal tumor who underwent radical laparoscopy from January 2020 to October 2021 at the Department of Gastrointestinal Surgery, Guizhou Provincial People's Hospital were recruited. The patients were marked by Nd-Fe-B magnet ring under endoscopy one day before the operation, another magnet ring was sent into the abdominal cavity during the radical laparoscopy through cannula. The two magnet rings were attracted and clung to each other to orient the lesions. The basic information of patients, location of preoperative marks under endoscopy and laparoscopy conditions were recorded.Results:All 51 Nd-Fe-B magnet rings were successfully located to the position of colorectal tumor and fixed. According to the location of the lesions, there were 15 cases of transverse colon, 12 cases of descending colon, 19 cases of sigmoid colon, and 5 cases of upper rectal segment. According to the lesion type, there were 21 cases of colon cancer, 25 cases of polyp carcinomatosis, and 5 cases of laterally spreading tumors with partial carcinomatosis. There were 5 cases with positive margins after endoscopic mucosal resection and 1 case with positive margin after endoscopic submucosal dissection. All lesions were accurately located during the operation. The marking time was 4.1±1.2 min (3-6 min) before the operation and the localization time was 1.5±1.1 min (0.9-5.3 min) during the operation. All magnet rings were removed from the body by laparoscope. The mean distances between the tumor and the cutting edge of the proximal and distal intestinal segments were 5.5 cm and 6.3 cm, respectively. No complications such as colon mucosal injury, bleeding, intestinal perforation or local inflammatory reactions occurred.Conclusion:Nd-Fe-B magnet ring tracer technique for laparoscopic orientation is simple, fast, accurate and safe with no need for additional equipment or apparatus, which is worthy of clinical application.

The median course of disease was 6 months (15 days to 40 years). Six cases underwent laparcoscopic cocoon membrane resection and intestinal adhesion lysis, of which 2 cases underwent laparotomy, one case was converted to open surgery, 4 cases underwent concomitant appendectomy. Follow-up ranged from 3 to 69 months, there were 2 cases complicating early inflammatory intestinal obstruction, 1 case suffred wound fat liquefaction and infection, 1 case with a colic 5 months after operation, and the others were doing well.Conclusions:The clinical characteristics of abdominal cocoon disease are not typical. Surgery is the main treatment. The prognosis of the disease is generally fair.
ABSTRACT
Objective:To compare the maternal and fetal outcomes of women with cervical insufficiency (CI) undergoing McDonald cerclage (MC) and laparoscopic cervicoisthmic cerclage (LCC), so as to provide evidence for the selection of cerclage methods.Methods:A retrospective trial was carried out in the First Affiliated Hospital of Sun Yat-sen University from January 2010 to December 2020. A total of 221 women who underwent the prophylactic cerclage were divided into MC group ( n=54), LCC with MC history group ( n=28) and LCC without MC history group ( n=129) by the mode of operation and whether the pregnant women who underwent LCC had MC history. General clinical data, pregnancy complications and pregnancy outcomes were compared between the three groups. Results:(1) General clinical data: the proportion of women accepted cervical cerclage during pregnancy in MC group, LCC with MC history group and LCC without MC history group were 100.0% (54/54), 7.1% (2/28) and 27.1% (35/129), respectively ( P<0.001). The indications of the three groups showed statistical significance ( P=0.003), and the main indication was the history of abortion in the second and third trimester [75.9% (41/54) vs 89.3% (25/28) vs 84.5% (109/129)]. (2) Pregnancy complications: the incidence of abnormal fetal position [7.8% (4/51) vs 17.4% (4/23) vs 19.8% (24/121)], placenta accrete [5.9% (3/51) vs 13.0% (3/23) vs 11.6% (14/121)], uterine rupture [0 vs 4.3% (1/23) vs 5.8% (7/121)] in the MC group were all lower than those in LCC with MC history and LCC without MC history groups. However, there were no statistical significances (all P>0.05). Intrauterine inflammation or chorioamnionitis [15.7% (8/51) vs 0 vs 0.8% (1/121)] and premature rupture of membrane [23.5% (12/51) vs 4.3% (1/23) vs 0] were both significantly higher in MC group than those in LCC with MC history and LCC without MC history groups (all P<0.001). (3) Pregnancy outcomes: the cesarean section rate was significantly lower in MC group (41.2%, 21/51) than that in LCC with MC history group (100.0%, 23/23) and LCC without MC history group (100.0%, 121/121; P<0.001). MC group was associated with lower expenditure than LCC with MC history and LCC without MC history groups (12 169 vs 26 438 vs 27 783 yuan, P<0.001). The success rates of live birth cerclage did not differ significantly in MC (94.4%, 51/54), LCC with MC history (82.1%, 23/28) and LCC without MC history (93.8%, 121/129) groups ( χ2=5.649, P=0.059). There was no significant difference in neonatal intensive care unit occupancy, neonatal birth weight and neonatal asphyxia between the three groups (all P>0.05). Conclusions:Both LCC and MC are the treatment choice for women with CI, which may get similar liver birth. However, MC has the advantages of low cesarean section rate, economical and easy operation. Therefore, MC is recommended as the first choice for CI patients, and LCC is for women with failed MC.
ABSTRACT
Objective:To investigate the clinical advantages of absorbable barbed wires in laparoscopy combined with choledochoscopy treatment of gallbladder polyps.Methods:The clinical data of 103 patients with gallbladder polyps who received laparoscopy combined with choledochoscopy treatment in The First People's Hospital of Lianyungang from February 2016 to March 2018 were retrospectively analyzed. Sixty-five patients in the observation group underwent gallbladder wall sutures with absorbable barbed wires, and thirty-eight patients in the control group underwent gallbladder wall sutures with common absorbable wires. The operative time, gallbladder wall suture time, intraoperative blood loss, average hospitalization time, and postoperative bile leakage were compared between the two groups.Results:There were no significant differences in intraoperative blood loss and average hospitalization time between the two groups ( P = 0.312, P = 0.114). In the observation group, gallbladder wall suture time and operative time were (5.58 ± 1.14) minutes and (60.71 ± 11.03) minutes, respectively, which were shorter than (6.32 ± 1.04) minutes and (68.24 ± 9.61) minutes in the control group ( t = 3.23, 3.50, P = 0.002, 0.001). No bile leakage occurred in the observation group and bile leakage occurred in four (10.5%) patients in the control group. There was a significant difference in bile leakage between the observation and control groups ( χ2 = 4.57, P = 0.032). Conclusion:Absorbable barbed wires for gallbladder wall sutures during operation in laparoscopy combined with choledochoscopy treatment of gallbladder polyps is safe and feasible. It can markedly shorten gallbladder wall suture time and operative time, decrease the incidence of bile leakage, and has a clinical advantage over common absorbable wires.
ABSTRACT
Objective:To explore the clinical efficacy and safety of single-layer with full thickness of duct-to-mucosa pancreaticojejunostomy in laparoscopic pancreaticoduodenectomy.Methods:The clinical data of 45 patients who underwent laparoscopic pancreaticoduodenectomy with the procedures of single-layer with full thickness in Second Hospital of Hebei Medical University from Jan 2020 to Jan 2022 were retrospectively collected and compared with 45 matched patients with traditional two-layer pancreaticojejunostomy.Results:The laparoscopic pancreaticoduodenectomy procedures were successfully performed in all the 90 cases. The mean operation time (285.6±92.4 minutes) and the media pancreaticojejunostomy time 20(15, 35) minutes) of the single-layer with full thickness pancreaticojejunostomy group were shorter than those of the two-layer pancreaticojejunostomy group [the mean operation time: 317.0±85.5 minutes, the media pancreaticojejunostomy time: 46(30, 58) minutes] with significantly statistical differences (all P value<0.05). There were no significantly statistical differences on intraoperative blood loss, the postoperative complications or hospital stay between the two groups. Conclusions:Compared with traditional pancreaticojejunostomy, the single-layer with full thickness of duct-to-mucosa pancreaticojejunostomy is simple and safe, which has the advantage of easy manipulation and less time-consuming and can be recommended for laparoscopic procedures.

Objective:To investigate the application of sentinel lymph node biopsy (SLNB) in early-staged cervical cancer by laparoscopy.Methods:It was a prospective, single-arm, single-center clinical study. Seventy-eight cases of cervical cancer patients were collected from July 2015 to December 2018 at the Fourth Hospital of Hebei Medical University. All the patients were injected with tracer into the disease-free block of cervical tissue after anesthesia by the same surgeon who learned sentinel lymph node (SLN) mapping technique in Memorial Sloan-Kettering Cancer Center, and underwent SLN mapping followed by complete pelvic lymphadenectomy. Moreover, all the dissected lymph nodes were stained with hematoxylin eosin staining (HE) pathological examination. Besides, the negative SLN on hematoxylin-eosin staining were detected by immunohistochemistry cytokeratin staining micro-metastasis. To analyze the distribution, detection rate, false negative rate the sensitivity and negative predictive value of the SLN in early-staged cervical cancer by laparoscopy, and explore the value of SLN mapping in predicting the lymph nodes metastasis in early-staged cervical cancer.Results:The overall detection rate of SLN in cervical cancer was 99% (77/78), bilateral detection rate was 87% (68/78). The average of 12.4 lymph node (LN) and 3.6 SLN were dissected for each patients each side. SLN of cervical cancer were mainly distributed in the obturator space (61.5%, 343/558), followed by external iliac (23.5%, 131/558), common iliac (7.3%, 41/558), para-uterine (3.8%, 21/558), internal iliac (2.2%, 12/558), para abdominal aorta (1.1%, 6/558), and anterior sacral lymphatic drainage area (0.7%, 4/558). Fourteen cases of LN metastasis were found among all 78 cases. There were a total of 38 positive LN, including 26 SLN metastasis and 12 none sentinel LN metastasis. Through immunohistochemical staining and pathological ultra-staging, 1 SLN was found to be isolated tumor cells (ITC), and 5 SLNs were found to be micro-metastases (MIC), accounting for 23% (6/26) of positive SLN. SLN mapping with pathological ultra-staging improved the prediction of LN metastasis in cervical cancer (2/14). Metastatic SLN mainly distributed in the obturator space (65%, 17/26), peri-uterine region (12%, 3/26), common iliac region (15%, 4/26), and external iliac region (8%, 2/26). The consistency of the diagnosis of lymph node metastasis by SLN biopsy and postoperative retroperitoneal lymph node metastasis showed that the Kappa value was 1.000 ( P<0.001), indicated that the metastasis status of SLN and retroperitoneal lymph node were completely consistent. The sensitivity, specificity, accuracy, false-negative rate, and negative predictive value of SLN biopsy in the diagnosis of lymph node metastasis were 100%, 100%, 100%, 0, and 100%, respectively. Conclusions:SLN in early-staged cervical cancer patients were mainly distributed in the obturator and external iliac space, pathalogical ultra-staging of SLN could improve the prediction of LN metastasis. Intraoperative SLN mapping is safe, feasible and could predict the state of retroperitoneal LN metastasis in early-staged cervical cancer. SLNB may replace systemic pelvic lymphadenectomy.
ABSTRACT
Objective:To explore the value of Hong′s single-stitch duct to mucosa pancreaticoenterostomy(HSDMP) in laparoscopic pancreaticoduodenectomy(LPD).Methods:The perioperative clinical data of 300 patients undergoing LPD admitted to the Second Department of Hepatobiliary Surgery in the First Hospital of Jilin University from April 2015 to March 2019 were retrospectively analyzed. The patients were categorized into pancreatic fistula group( n=43) and non pancreatic fistula group( n=257). according to the presence or absence of postoperative pancreatic fistula. Among them, pancreaticojejunostomy was performed with HSDMP in 210 patients, and 90 patients underwent traditional pancreaticoenterostomy. Univariate and multivariate logistic regression were used to analyze the risk factors for the development of pancreatic fistula after LPD, and the difference on the time of pancreaticojejunostomy and the incidence of postoperative pancreatic fistula were compared between HSDMP and traditional pancreaticojejunostomy. Results:Univariate analysis showed that the differences on BMI, abdominal operation history, pancreatic texture, and pancreatic duct diameter were statistically significant compared with non-pancreatic fistula group (all P value <0.05). Multivariate logistic regression showed that BMI ( OR1.180, 95% CI1.047-1.338, P=0.008) and pancreatic texture( OR=0.375, 95% CI 0.135-0.861, P=0.036) were independent risk factors for pancreatic fistula after LPD. Compared with traditional pancreaticojejunostomy, HSDMP was associated with shorter anastomosis time and low incidence of postoperative pancreatic fistula, but there was no statistical significance between the two groups. Conclusions:The independent risk factors for pancreatic fistula are high BMI and soft pancreatic texture. Compared with traditional pancreaticojejunostomy, HSDMP does not prolong LPD time and increase the incidence of postoperative pancreatic fistula.
ABSTRACT
Objective:To investigate the effect of conducting general anesthesia with sevoflurane combined with remifentanil on the anesthetic effect and stress indexes in patients undergoing laparoscopic hysterectomy.Methods:A total of 80 patients undergoing laparoscopic hysterectomy in the Affiliated Hospital of Jining Medical College from April 2020 to August 2020 were selected and divided into the observation group and the control group according of the number table method, with 40 cases in each group. In the control group, sufentanil, propofol and rocuronium were used to induce anesthesia, and propofol and remifentanil were intravenously administered during anesthesia maintenance.The observation group received the same induction anesthesia, followed by 2% sevoflurane inhalation combined with remifentanil to maintain anesthesia. The anesthetic effect, stress indexes at different postoperative time points and adverse reaction between the two groups were compared.Results:The scores of mini mental state evaluation (MMSE) at 0.5, 1 and 2 h after the surgery and the scores of observer′sassessment of alertness/sedation scale (OAA/S) atimmediately after extubation, 1 and 2 h after surgery in the observation group were higher than those in the control group, there were statistical differences ( P<0.05). The wake up time and extubation time in the observation group were shorter than those in the control group: (9.22 ± 1.67) min vs. (15.94 ± 1.44) min, (10.34 ± 1.46) min vs. (17.11 ± 1.33) min, there were statistical differences ( P<0.01). The systolic blood pressure, diastolic blood pressure, epinephrine and cortisol at 10 min after intubation and at the end of surgery in the observation group were lower than those in the control group, there were statistical differences ( P<0.05). Conclusions:Sevoflurane combined with remifentanil conducting anesthesia can better improve the cognitive function of patients, shorten the recovery time of postoperative consciousness, and reduce the intraoperative stress response.
ABSTRACT
Objective:To explore the risk factors of seroma after laparoscopic totally extraperitoneal hernia repair.Methods:The clinical data of 236 patients underwent laparoscopic totally extraperitoneal hernia repair from July 2018 to June 2021 in Jiaozhou Central Hospital of Qingdao City were retrospectively analyzed. The related risk factors of seroma after laparoscopic totally extraperitoneal hernia repair were analyzed.Results:Among 236 patients, the seroma occurred in 36 cases (seroma group), the incidence of seroma was 15.25%; no seroma occurred in 200 cases (non-seroma group). There were statistical differences in the duration of disease ≥5 years, scrotal hernia, internal inguinal ring defect ≥3 cm, rupture of hernia sac, experience of operators <5 years between 2 groups ( P<0.01 or <0.05); there were no statistical difference in age, body mass, type of patch, preoperative complications (including diabetes, chronic obstructive pulmonary disease and cardiac cerebrovascular disease) and operative time between 2 groups ( P>0.05). Multivariate Logistic regression analysis result showed that the duration of disease ≥5 years, scrotal hernia, rupture of hernia sac and experience of operators<5 years were independent influencing factors of seroma after laparoscopic totally extraperitoneal hernia repair ( OR = 5.147, 5.006, 0.044 and 3.315; 95% CI 1.513 to 17.516, 1.845 to 13.583, 0.008 to 0.240 and 1.029 to 10.679; P<0.01 or<0.05). Conclusions:The duration of disease ≥5 years, scrotal hernia, rupture of hernia sac and experience of operators<5 years are independent influencing factors of seroma after laparoscopic totally extraperitoneal hernia repair, and preoperative assessment of risk factors is helpful to reduce the incidence of seroma.
ABSTRACT
Objective:To investigate the safety and curative effect of transumbilical single-incision laparoscopy with fascial platform for ovarian cystectomy.Methods:The clinical data of 105 patients underwent laparoscopy ovarian cystectomy in Fujian Maternity and Child Health Hospital from June 2018 to December 2021 were retrospectively analyzed. Among them, 45 patients underwent transumbilical single-incision laparoscopy with fascial platform for ovarian cystectomy (observation group), and 60 patients underwent multi-port laparoscopy for ovarian cystectomy (control group). The operative time, intraoperative bleeding, conversion to open surgery, cyst rupture, surgical collateral injury, postoperative exhaust time, postoperative hospital stays, hospitalization cost and postoperative infection, etc were recorded. The face rating scale (FRS) was used to evaluate the pain at 6 and 24 h after operation; the incision satisfaction was evaluated by the Kiyak satisfaction scale at 2 months after operation.Results:The operation was carried out successfully in both groups without surgical collateral injury or conversion to open surgery. There were no significant differences in operative time, intraoperative bleeding, postoperative hospital stays, hospitalization cost, cyst rupture rate and postoperative infection rate between 2 groups ( P>0.05); the postoperative exhaust time and FRS 6 and 24 h after operation in observation group were significantly less than those in control group: (22.1 ± 3.5) h vs. (23.9 ± 3.8) h, 1 (0, 2) scores vs. 2 (1, 4) scores and 1 (0, 1) scores vs. 1 (0, 2) scores, the incision satisfaction score was significantly higher than that in control group: 5 (4, 5) scores vs. 4 (3, 4) scores, and there were statistical differences ( P<0.05 or <0.01). Conclusions:Transumbilical single-incision laparoscopy with fascial platform for ovarian cystectomy is safe and feasible, with concealed incision and high patient satisfaction, and has good clinical application value.
ABSTRACT
Objective:To evaluate the feasibility and perioperative safety of retroperitoneal laparoscopic nephrectomy for autosomal dominant polycystic kidney disease (ADPKD) before kidney transplantation.Methods:A total of 22 patients with ADPKD who underwent laparoscopic polycystic nephrectomy before kidney transplantation in Beijing Friendship Hospital, Capital Medical University from January 2013 to December 2020 were enrolled in this retrospective study. Preoperative epidemiological data, operation time, intraoperative blood loss, perioperative blood transfusion, conversion rate, postoperative gastrointestinal function recovery time, drainage tube placement time, postoperative hospital stay, incidence and severity of complications were collected.Results:The mean age of all patients in this study was (50.95±9.28) years old, and the mean preoperative polycystic kidney diameter was (18.83±2.38) cm. In all patients, 20 patients were scheduled for polycystic nephrectomy due to transplantation and 2 patients were done for polycystic renal cyst rupture and hemorrhage. The mean operation time of all patients was (191.14±70.46) min, and the median intraoperative blood loss was 100 mL. Among them, 5 patients had large intraoperative blood loss, and were given intraoperative blood transfusion. Two of all patients were converted to open due to severe intraoperative adhesions. In terms of postoperative recovery, the mean recovery time of gastrointestinal function was (2.09±0.61) d, the mean time of abdominal drainage tube placement was (5.32±2.08) d, the mean postoperative hospital stay was (7.55±2.34) d. In terms of postoperative complications, 4 patients developed postoperative incision pain, bleeding or other complications, but all improved after symptomatic treatment.Conclusions:For patients with ADPKD, original polycystic kidney can be effectively resected by retroperitoneoscopy before transplantation. At the same time, the operation time is short, and patients have quick postoperative recovery, even the incidence and severity of postoperative complications are low. Therefore, retroperitoneal laparoscopic nephrectomy can be used as the first choice for the removal of original polycystic kidney before renal transplantation in ADPKD patients.
