Sutureless re-anastomosis by laparoscopy versus microsurgical re-anastomosis by laparotomy for sterilization reversal: a matched cohort study

BACKGROUND: Sutureless re-anastomosis per laparoscopy is an alternative for microsurgical re-anastomosis by laparotomy in the treatment of sterilized women with renewed child wish. Our aim was to compare pregnancy rates after both surgical techniques. METHODS: We performed a retrospective cohort study in which consecutive women who underwent sutureless re-anastomosis per laparoscopy were compared to women who underwent microsurgical re-anastomosis by laparotomy. Both procedures were performed in neighbouring hospitals in Northern-Brabant, The Netherlands, and women were matched for age. The primary outcome was time to ongoing pregnancy. RESULTS: Overall, we included 41 women who had sutureless re-anastomosis by laparoscopy, and 41 age-matched women who underwent microsurgical re-anastomosis by laparotomy. The number of women who conceived was 20 (15 ongoing pregnancies) in the sutureless laparoscopic group versus 26 (24 ongoing pregnancies) in the laparotomic group, a difference due to a longer follow-up period in the laparotomic group. Time to ongoing pregnancy was comparable in both groups (P=0.46), with 3 year cumulative ongoing pregnancy rates of 45 and 52% respectively. After adjustment for other prognostic factors, the fecundity rate ratio was 0.97 (95% CI 0.26-3.6), indicating a similar performance of the two techniques. CONCLUSION: The simplified stitchless laparoscopic procedure for reversal of tubal sterilization with the use of a tubal splint, clip fixation of the muscularis and fibrin glue resulted in a promising pregnancy rate, which was similar to the pregnancy rate obtained with the microsurgical re-anastomosis per laparotomy.     

Prevention of de-novo adhesion formation after laparoscopic myomectomy: a randomized trial to evaluate the effectiveness of an oxidized regenerated cellulose absorbable barrier

To evaluate the effectiveness of the oxidized regenerated celluloseabsorbable barrier (Interceed®, TC7) in the prevention ofde-novo adhesion formation after laparoscopic myomectomy, aprospective and randomized study was performed at the Departmentof Obstetrics and Gynaecology of the University of Cagliari,Cagliari, Italy. A total of 50 pre-menopausal non-pregnant women,aged 23—42 years, who submitted to laparoscopic myomectomyfrom January 1993 to June 1994, were randomized to surgery alone(control group, n = 25) or surgery and oxidized regeneratedcellulose barrier (Interceed group, n = 25). Neither group receivedany other treatment for adhesion prevention. A second-look laparoscopywas performed 12—14 weeks after laparoscopic myomectomy.The incidence of adhesion-free patients was assessed at second-looklaparoscopy by an investigator not informed of the treatment.The numbers of adhesion-free patients were three out of 25 (12%)in the control group and 15 out of 25 (60%) in the treatmentgroup (P < 0.05). In conclusion, the oxidized regeneratedcellulose absorbable barrier significantly reduced de-novo adhesionformation after laparoscopic myomectomy.     

轻度过度通气下施行CO2气腹对呼吸和动脉血气的影响

目的观察轻度过度通气下施行CO2气腹对呼吸和动脉血气的影响.方法行择期腹腔镜胆囊切除术(LC)病人术前快速诱导麻醉,气管内插管后行机械通气,吸入N2O、持续静脉输注异丙酚维持全麻,硬膜外间断给药.分别在诱导前5 min、气腹前1min和气膜后5、10、20、30、40、50、60min及放气后5 min记录各监测值,同时采桡动脉血作血气分析.结果气腹开始后20～60min,呼气末CO2分压(PETCO2)和Co2排出量(VCO2)较气腹前显著升高.气腹开始后,pH值逐渐降低,30 mm时较诱导前显著降低;PaCO2逐渐升高,60min时较诱导前显著升高,但PETCO2、VCO2、PaCo2及pH的变化均在正常范围.在气腹初期,气道压(PAW)较气腹前显著升高,而呼气分钟通气量(MVE)较气腹前明显降低.结论采用异丙酚静脉全麻复合硬膜外麻醉及气腹前适当过度通气的呼吸管理方式在LC中是切实可行的.

目的 探讨腹腔镜术中处理复杂性胆囊结石及胆总管结石的不同方式对手术的影响。方法回顾性分析青岛市市立医院收治的复杂性胆囊及胆总管结石患者136例,总结并归纳术中情况及相对应处理技巧及经验。结果 本研究中腹腔粘连病例占全组120例（88.2%）,其中炎症粘连73例,手术后粘连47例,术中遵循“宁伤胆囊、远离肝门”的处理原则及相应的处理技巧,98例（81.7%）腹腔粘连患者按照原定手术方式顺利完成,但22例（18.3%）腹腔粘连患者因术中胆总管或胆囊颈管辨别不清、术中发现胆囊癌变等原因施行中转开腹手术。结石嵌顿病例占全组16例（11.8%）,包括胆囊颈管及胆总管结石嵌顿,术中应用推挤法、直接取石法、液电碎石等技巧联合应用胆道镜、碎石仪及扩张球囊等设备,手术均在腹腔镜下完成。结论 腹腔粘连和结石嵌顿是腹腔镜下复杂性胆囊结石及胆总管结石手术中较常见的困难,相应的术中决策和处理技巧能够为提高患者安全、降低手术风险、减少术后并发症等提供更多的方法与思路。     

Experience managing distal ureteral strictures with Boari flap-psoas hitch and comparison of open and laparoscopic procedures

BackgroundTo summarize our experience with the Boari flap-psoas hitch and compare the indications, perioperative data and outcomes between open and laparoscopic procedures.MethodsThis study retrospectively reviewed 35 patients with complex distal ureteral stricture between January 2015 and April 2019. All patients were treated with Boari flap-psoas hitch by either an open or a laparoscopic procedure. Selection criteria were based on the etiology, comorbidities, medical history, and patient preference.ResultsAll surgeries were performed successfully. The median operation time was 201 min (range, 120 to 300 min), and the median estimated blood loss was 50 mL (range, 20 to 400 mL). The median postoperative hospitalization was 9 days (range, 3 to 46 days). Nineteen patients were treated by the open procedure, and 16 were treated by the transperitoneal laparoscopic procedure. The surgical indication of open surgery was broader than that for laparoscopic surgery. For patients experiencing iatrogenic injury and ureterovesical reimplantation failure, no significant differences in sex, laterality, operative time, ASA score or postoperative hospitalization stay were observed between the two groups. The median estimated blood loss was lower in the laparoscopic group than in the open group (P=0.047). Patients in the open group had more surgical complications than patients in the laparoscopic group (P=0.049). The postoperative follow-up showed the radiological resolution of hydronephrosis in 33 patients.ConclusionsWith the appropriate surgical considerations, Boari flap-psoas hitch is a valid method to bridge distal ureteral defects. For select patients, laparoscopic surgery had advantages being a minimal invasive surgery with less estimated blood loss and fewer surgical complications.

COMPLICATIONS IN LAPAROSCOPIC GYNECOLOGIC SURGERY

Objective. To investigate retrospectively the complications and associated factors of gynecological laparescopies.Methods. 1769 laparoscopic surgeries were carried out from January 1994 to October 1999 at our department. The procedures included 1421 surgeries of ovary and tube, 52 myomectomies and 296 cases of laproscopic-assisted vaginal hysterectomy (LAVH). A total of 312 patients had a history of prior laparotomy (17.6%). Results. Complications occured in 34 cases, the overall complication rate was 1.92%. Unintended laparotomies occured in 6 cases(0.34% ). 12 complications were associated with insertion of Veress needle or trocar and creation of pneumoperitoneum, including 5 severe emphysema and 7 vascular injuries, this figure represents 35.3% of all complications of this series. Five intraopemtive complications (14.7 % ) occured during the laparescopic surgery (3 severe bleedings, one bladder injury and one skin bum of leg caused by damaged electrode plate), laparotomy was re-quired in four of these cases. Seventeen complications occured during postoperative stage: 2 intraperitoneal hemor-rhages needing laparotomy, 2 bowel injuries, 4 nerve paresis and 9 febrile morbidities. Cordusions. Operative gynecologic laparoscopy is associated with acceptable morbidity rate, but can not be over-looked. Complication rate seems to be higher in advanced procedures such as LAVH.     

Gastric Banding: Advantages and Complications. A 5- and 10-Year Follow-up

Background: Gastric banding is one of the simplest surgical procedures for the treatment of morbid obesity. We performed more than 150 ‘laparotomy’ (open) gastric bandings and more than 50 ‘laparoscopic’ bandings in the last 10 years. Methods: In most procedures we used non-adjustable bands, but since the beginning of 1995 we have used adjustable silicone banding. Results: The 5- and 10-year follow-up weight loss results are encouraging. The average long-term weight loss was 35.5 kg. Since 1993, we performed all the procedures laparoscopically, and the postoperative complications decreased from 18.5% in the ‘laparotomy’ group to 9.5% in the ‘laparoscopic’ group, with the majority being esophagitis and outlet area irritation. Conclusion: Gastric banding itself and especially the minimally invasive laparoscopic approach is an easy technical procedure. The long-term weight loss results and the reoperation rate are acceptable for bariatric surgery criteria.
