ObjectiveTo observe the effects and security of dexmedetomidine in combined spinal epidural anesthesia (CSEA) for laparoscopic total extraperitoneal hernia repair (TEP). MethodsFrom January 2010 to January 2013, we selected 90 patients who were going to receive TEP surgery as our study subjects. The patients were divided into three groups:M1, M2 and M3 with 30 patients in each. The patients had left lateral position, and anesthesia was done between 3-4 lumbar epidural line. Injection of 0.5% bupivacaine 2 mL was carried out, and epidural catheter was 3-5 cm. Anesthesia plane was adjusted from the chest 4 or 6 vertebra to the sacral vertebra. The three groups of patients were treated with micro pump using dexmedetomidine given at a pre-charge of 0.5 μg/kg, and then group M1 was maintained by 0.3 μg/(kg·h), M2 by 0.5 μg/(kg·h), and M3 by 0.7 μg/(kg·h). The changes of mean arterial pressure (MAP), heart rate, respiration and pulse oximetry (SpO2) were observed at each time point, and bispectral index (BIS) monitor and Ramsay sedation score test were also conducted. ResultsThe changes of MAP, heart rate and respiration in group M1 were not obvious; the Ramsay score for group M1 was 2 to 3, and BIS value after pre-charge was 65-84. For group M2, MAP, heart rate and respiration had a slight decline; Ramsay score was 3-5 points, and BIS value was 60-79. In group M3, patients had a milder decline in their MAP and respiration; the heart rate declined obviously after receiving dexmedetomidine and one patient with severe decline of the heart rate alleviated after active treatment; Ramsay score was 5 to 6 points, and BIS value was between 55 and 75. There was little change in SpO2 in all the three groups, and the difference was not statistically significant (P>0.05). ConclusionContinuous injection of dexmedetomidine at 0.3-0.5 μg/(kg·h) in CSEA is an alternative way for anesthesia, which can effectively promote sedation and reduce pain and discomfort.
ObjectiveTo summarize the data of robotic hysterectomy in patients with large and super-large uterus in single center, and explore the relevant clinical experience and advantages of robotic surgery.MethodsThe medical records of the patients with large uterus caused by gynecological diseases who underwent robotic hysterectomy in the Chinese PLA General Hospital from January 2016 to December 2018 were retrospectively analyzed. The patients with uterine size from 12 to 16 weeks of gestation were divided into large uterus group and those with uterine volume larger than 16 weeks of gestation were divided into super large uterus group.ResultsA total of 62 patients were included, including 28 in the large uterus group with the average uterus size of (14.3±2.1) gestational weeks, and 34 in the super large uterus group with the average uterus size of (19.9±2.8) gestational weeks. There was no significant difference in mean age, body mass index, history of abdominal surgery or diagnostic composition between the two groups (P>0.05), except for the size of the uterus (t=8.772, P<0.001). The operation time in the large uterus group was less than that in the super-large uterus group [(75.4±22.6) vs. (91.7±27.8) min; t=2.495, P=0.015]. The incidence of complications after robotic hysterectomy was 14.5% (9/62) in the 62 patients, including 14.3% (4/28) in the large uterus group and 14.7% (5/34) in the super-large uterus group. There was no significant difference in the amount of bleeding, blood transfusion rate, ratio of conversion to open surgery, average hospitalization days or incidence of postoperative complications between the two groups (P>0.05).ConclusionsRobotic hysterectomy has the advantages of flexible manipulator, 3-D operative field of vision and stability of manipulation. In addition, increased uterine volume does not lead to increased surgical trauma, nor apparently affect the prognosis.
ObjectiveTo investigate the effectiveness of the tubal reconstruction after laparoscopic tubal pregnancy operation by comparing with simple laparoscopic tubal pregnancy operation. MethodsBetween May 2007 and May 2010, 63 patients with tubal pregnancy underwent laparoscopic tubal pregnancy operation and tubal reconstruction in 30 cases (trial group) or simple laparoscopic tubal pregnancy operation in 33 cases (control group). There was no significant difference in age, pregnancy time, and position between 2 groups (P gt; 0.05). The tube patency test and hysterosalpingography (HSG) were carried out to evaluate the efficacy. ResultsThe operation was successfully completed in 29 cases of trial group; 1 case had too severe adhesion to receive re-anastomosis and was excluded. The tube patency test showed that the tube was patency in 26 cases of trial group and in 2 cases of control group during operation, showing significant difference (Z=5.86, P=0.00); it was patency in 25 cases of trial group and in 26 cases of control group at 1 month after operation, showing no significant difference (Z=0.48, P=0.63). HSG examination showed tube was patency in 25 cases of trial group and in 2 cases of control group at 2 months after operation, showing significant difference (Z=5.35, P=0.00). After 24 months, intrauterine pregnancy of trial group (n=25, 86.20%) was significantly higher than that of control group (n=19, 57.58%) (χ2=7.72, P=0.01). ConclusionThe reconstruction after laparoscopic tubal pregnancy operation can significantly increase the intrauterine pregnancy rate, and it is better than simple laparoscopic tubal pregnancy operation.
ObjectiveTo evaluate the security and feasibility of transumbilical laparoendoscopic single-site cholecystectomy (TULESC) with conventional laparoscopic instruments. MethodsThe clinical data of 62 adult patients undergoing TULESC between October 2011 and June 2013 were analyzed retrospectively. There were 13 males and 49 females aged between 22 and 70 years old averaging 40±15. Forty-nine patients suffered from chronic cholecystitis with cholelithiasis, 10 from asymptomatic cholelithiasis and 3 from cholecystic polyposis. A single arc incision was cut on the edge of the umbilicus, and two 10 mm Trocars and one 5 mm Trocar were placed by puncture. Cholecystectomy was performed with conventional laparoscopic instruments and equipment. ResultsAll the 62 patients underwent TULESC successfully without severe complications such as bile leakage or biliary injury. The operation time was 20-70 minutes with the average of (40±15) minutes; The blood loss was 5-40 mL with the average of (15±10) mL. All the patients were discharged from the hospital within 3 to 7 days after surgery, averaging 4.0±1.0. During the 1 to 12-month follow-up (averaging 3 months), there was no obviously visible scars on the abdominal wall and the aesthetic effect was significant. ConclusionTULESC with conventional laparoscopic instruments and equipment is safe, feasible and cosmetic.
ObjectiveTo explore the effect of laparoscopic partial recto-sigmoid resection with rectopexy for adult complete rectal prolapse. MethodsClinical data of 32 adult patients with complete rectal prolapse who underwent laparoscopic partial recto-sigmoid resection with rectopexy in our hospital from May. 2010 to May. 2013 were analyzed. ResultsAll operations were performed successfully and all patients were cured, no one transferred to open surgery. The mean of operation time was 114.7 min (95-167 min), the mean of operative blood loss was 80 mL (55-150 mL), and the mean of hospital stay was 9.8 d (6-14 d). All patients were followed up for 3-48 months (mean of 25.6 months), and anal function of them recovered well. During the follow-up period, there were no operative complications and recurrent case. ConclusionsLaparoscopic partial recto-sigmoid resection with rectopexy is a safe and effective procedure for the treatment of adult complete rectal prolapse, with minimal invasion, quick recovery, and a low recurrence rate. It provides a novel surgical method with a high value of clinical application.
ObjectiveTo compare clinical efficacy of totally laparoscopic gastrectomy (TLG) and conventional laparoscopy-assisted gastrectomy (LAG) and to explore safety and feasibility of total laparoscopic anastomosis in laparoscopic gastrectomy. MethodThe clinical data of 64 patients who received TLG and another 70 patients who received conventional LAG in our department from January 2013 to March 2014 were retrospectively analyzed. ResultsAll procedures were completed successfully. There were no significant differences in the time of anastomosis〔(73.8±10.3) min versus (72.7±8.9) min, t=0.693, P=0.489〕 and the number of dissected lymph nodes (32.4±9.7 versus 33.6±9.6, t=-0.700, P=0.485) between the patients underwent TLG and the patients underwent LAG. However there were obvious differences in the blood loss〔(275.0±66.3) mL versus (364.3±75.7) mL, t=-7.419, P=0.000〕, the incision length〔(3.0±0.8) cm versus (7.3±1.7) cm, t=-19.354, P=0.000〕, the time to fluid diet〔(4.9±0.8) d versus (6.0±0.7) d, t=-8.750, P=0.000〕 and the time to flatus 〔(2.8±0.8) d versus (3.9±0.8) d, t=-8.388, P=0.000〕, the off-bed time〔(1.3±0.5) d versus (3.4±1.2) d, t=-14.118, P=0.000〕, and the hospital stay〔(9.8±1.2) d versus (13.0±1.5) d, t=-17.471, P=0.000〕 between the patients underwent TLG and the patients underwent LAG. Meanwhile it was found that the postoperative pain score〔On day 1 postoperatively: (3.4±0.8) points versus (6.2±1.3) points, t=-15.509, P=0.000; on day 3 postoperatively: (1.7±0.6) points versus (4.0±0.8) points, t=-18.799, P=0.000〕 and the dosage of pain killers (1.7±0.7 versus 4.0±2.1, t=-8.912, P=0.000) in the patients underwent TLG were significantly lower than those in the patients underwent LAG. One patient developed anastomotic leakage and 3 patients developed anastomotic stenosis in the patients underwent LAG, the complication rate related to the anastomosis was 5.7% (4/70). While there were no complications related to the anastomosis in including anastomotic leakage, stenosis, and bleeding in the patients underwent TLG. ConclusionsTotal laparoscopic anastomosis is safe and feasible in laparoscopic gastrectomy for gastric cancer. Compared with small incision-assisted anastomosis, totally laparoscopic anastomosis is associated with minimal trauma, less blood, quicker postoperative recovery, shorter time, slighter pain and satisfactory short-term efficacy.
ObjectiveTo explore the diagnostic and therapeutic significance of laparoscopic surgery for abdominal trauma patients. MethodsClinical data of 65 patients with abdominal trauma who treated in Affiliated Laigang Hospital of Taishan Medical College from January 2010 to December 2014 were collected retrospectively, all patients were diagnosed by laparoscopic exploration, and therapies were depended on the results of laparoscopic exploration. ResultsOf the 65 patients, 60 patients were definitely diagnosed through laparoscopic exploration, but 5 patients transferred to laparotomy because of clear diagnosis was not achieved under laparoscopy. Of the 60 patients who were diagnosed clearly by laparoscopy, 23 patients didn't received any intervention because of no obvious injury observed, 27 patients received laparoscopic surgery (3 patients were assisted with hands), and 10 patients transferred to open operation because of peritoneal contamination. Incision infection occurred in 1 patient after operation, 1 patient suffered from subphrenic abscess, and other 63 patients didn't suffered from any complication. All of the patients were discharged successfully. All of the 65 patients were followed up for 2-48 months with the median time of 10 months. Severe complications did not occurred and no patient needed re-operation within the period of follow-up period. ConclusionsLaparoscopy is feasible, safe, and effective for the evaluation and treatment of abdominal trauma patients with stable hemodynamics, and it also has a higher diagnostic rate. Laparoscopy can also reduce the negative exploratory laparotomy for the abdominal trauma patients.
Objective To investigate the impact of conversion to open in laparoscopic rectal cancer radical resection (LRR) on postoperative recovery. Methods The data from Feb. 2003 to Feb. 2007 of 176 cases who were given LRR and 32 cases receiving conversion in LRR (CRR) were analyzed retrospectively, and were compared about operation time, hospitalization time, hospitalization expenses, intraoperative blood loss, recovery time of bowel movement and postoperative complications with 59 cases of open rectal cancer radical resection (ORR). Results There were no differences among LRR, CRR and ORR about operation time, hospitalization time, intraoperative blood loss and recovery time of bowel movement (Pgt;0.05). The hospitalization expenses of LRR and CRR were higher than that of ORR (P=0.001, P=0.001), there was no difference between CRR and LRR (P=0.843). But the postoperative complications rate of ORR was higher than those of LRR and CRR （P=0.023,P=0.004）. Conclusion Compared with ORR, LRR has relatively conversion rate, and then increases the hospitalization expenses.
Objective To explore the methods， clinical effects， and application value of laparoscopic splenectomy combined with pericardial devascularization. Methods The clinical data of 23 patients with liver cirrhosis and portal hypertension who performed laparoscopic splenectomy combined with pericardial devascularization between july 2009 and july 2012 in our hospital were analyzed retrospectivly. Results In 23 cases， 2 cases were converted laparotomy due to bleeding， 21 cases were successfully performed laparoscopic splenectomy combined with pericardial devascularization. The operative time was 230-380 minutes （average 290 minutes）. The intraoperative blood loss was 300-1 500 mL （average 620 mL）. The postoperative fasting time was 1-3 days （average 2 days）. The postoperative hospital stay was 8-14 days （average 10 days）. Conclusion Laparoscopic splenectomy combined with pericardial devascularization is a feasible， effective， and safe procedure as well as minimally invasive hence is applicable for patients with portal hypertension and hypersplenism．
ObjectiveTo summarize clinical experiences of combination of laparoscope,choledochoscope,and balloon nasobiliary exploration (LCBNE) in treatment of cholecystolithiasis combined with choledocholithiasis with small diameter (0.3-0.8 cm) of common bile duct (CBD). MethodsFrom April 2010 to May 2015,there were 43 cases of cholecystolithiasis combined with choledocholithiasis with small diameter of CBD underwent LCBNE,involving choledochotomy,choledochoscopic exploration,electrohydralic lithothipsy,balloon nasobiliary dilatation for removing cholelith,nasobiliary drainage,and the primary closure of incision. ResultsThe procedure was successful in 27 cases of removing the bile duct residual stones through the choledochoscopic procedure,9 cases through the balloon nasobiliary procedure,and 7 cases were converted to endoscopic sphincterotomy for choledocholithasis.No case was converted to open CBD exploration.No case had residual stone.Bile leakage occurred in 1 case,which was cured by peritoneal drainage and nasobiliary drainage.One patient had a slight pancreatitis after operation.One patient had the stenosis of primary suture of CBD incision.Total postoperative complications rate was 7.0%(3/43).No case had perforations of intestine and bile duct,bleeding,severe pancreatitis,and death after operation. ConclusionFrom preliminary results of limited cases in this study,if patients are indicated,combination of LCBNE in treatment of cholecystolithiasis combined with choledocholithiasis with small diameter of CBD is safe and effective.
