However, vascular surgery via laparoscopy requires advanced skills and techniques;thus, this procedure needs to be simplified while maintaining quality of the surgery to make it a preferred technique for the surgeons. Methods: There were 49 patients who underwent laparoscopic sigmoidectomy or anterior resection till T2 level for sigmoid colon cancer and recto-sigmoid colon cancer. We analyzed short-term and long-term outcomes between stapling ligation and clipping ligation techniques used in these surgeries. Results: The mean volume of blood loss in the stapling ligation group was 12.8 ± 12.3 ml, which was significantly lower than 41.9 ± 71.2 ml of mean volume of blood loss in the clipping ligation group. There was no significant difference in the mean duration of surgery, the mean number of harvested lymph nodes, morbidity, recurrence, and 5-year relapse free survival rates between the 2 groups. Conclusions: This study demonstrates a surgical technique using staplers for vascular treatment of tumor-feeding arteries as a new technical improvement in laparoscopic colectomy for the treatment of early-stage colon cancer. We found that the described procedure was technically safe, simple, convenient, and oncologically valid.展开更多

The increased risk of intraoperative hemorrhage and potential hysterectomy has led many teams to contraindicate it, postponing it three to six months after delivery, thus giving more time for uterine involution, myoma shrinkage and reducing operative time and blood loss. Clinical Observation: We report the case of a polymyomectomy after use of a segmental tourniquet and bilateral ligation of the hypogastric arteries during a cesarean section for hemorrhagic placenta previa at the end of a spontaneous pregnancy of 28 weeks of amenorrhea in a 42-year-old nulliparous primigravida patient. Conclusion: Polymyomectomy during cesarean section is possible and requires knowledge of preventive hemostasis techniques and surgical experience.展开更多

Historical and ...Aim of the study is to comprehensively review the latest trends in laparoscopic complete mesocolic excision(CME) with central vascular ligation(CVL) for the multimodal management of right colon cancer. Historical and up-to-date anatomo-embryological concepts are analyzed in detail,focusing on the latest studies of the mesenteric organ,its dissection by mesofascial and retrofascial cleavage planes,and questioning the need for a new terminology in colonic resections. The rationale behind Laparoscopic CME with CVL is thoroughly investigated and explained. Attention is paid to the current surgical techniques and the quality of the surgical specimen,yielded through mesocolic,intramesocolic and muscularis propria plane of surgery. We evaluate the impact on long term oncologic outcome in terms of local recurrence,overall and disease-free survival,according to the plane of resection achieved. Conclusions are drawn on the basis of the available evidence,which suggests a pivotal role of laparoscopic CME with CVL in the multimodal management of right sided colonic cancer: performed in the right mesocolic plane of resection,laparoscopic CME with CVL demonstrates better oncologic results when compared to standard non-mesocolic planes of surgery,with all the advantages of laparoscopic techniques,both in faster recovery and better immunological response. The importance of minimally invasive mesoresectional surgery is thus stressed and highlighted as the new frontier for a modern laparoscopic total right mesocolectomy.展开更多

Complete mesocolic excision(CME) is widely acclaimed as the new goldstandard in colon cancer resections, thus it is imperative to establish quality criteria of CME in order to make it easily understood and verified by surgeons worldwide. One simple and reproducible tool could be the measurement of arterial stumps postoperatively and a straightforward way to test its reliability is to test it in a comparative study between CME and non-CME surgery.AIM To validate arterial stump measurement as a surgical quality tool by comparing CME with conventional radical colectomies.METHODS This was a retrospective study, carried out on a prospective database. We collected data from two groups of patients, divided according to standard CME with D2 central vascular ligation(group A) and non-standardized surgery(group B). The two groups were compared with regard to the arterial stump length after right-and left-sided colectomies for colon cancer. The actual stump lengths of the ileocolic artery(ICA) and inferior mesenteric artery(IMA) were compared with their theoretical best D2 position of predicted ligation levels(D2 PLLs) for calculating the potential for improvement. Measurements on follow-up computed tomography scans were carried out by three observers. Pathological data were recorded(specimen length, lymph node yield) and correlated with stump length.RESULTS We analysed 58 colectomies. The stump lengths(mean ± SD) in group A were16.97 ± 4.77 mm for ICA and 31.70 ± 15.71 mm for IMA, whereas group B had 49.93 ± 20.29 mm for ICA and 67.24 ± 28.71 mm for IMA. Shorter lengths were obtained in group A, by a mean difference of 35.66 mm(χ~2 = 27.38, P < 0.001),which was significant for all types of colectomies. Except for a 5.85 ± 4.71 mm difference for right colectomies, all the ligations from group A significantly reached their potential height(0.26 ± 12.1展开更多
