Minimally Invasive Insufflation Technique Is and Should Not Be a “Black Box” Principle

Reply

“…In our practice, pneumoperitoneum is created using a disposable Veress needle (Endopath Pneumoneedle Insufflation Needle; Ethicon Endo-Surgery, Inc., Cincinnati, OH) inserted in the umbilicus. Of note, the maximum volume of CO 2 insufflated in the abdomen is \4 L/min according to simple physical law, well reported in the investigation by Jacobs et al [1,4]. For CO 2 insufflation we use an Endoflator (Karl Storz Endoskope, Tuttlingen, Germany).…”

“…We thank Jacobs et al [1] for their interest in our recent articles [2,3]. In performing our study of the effect of pneumoperitoneum pressure on postoperative outcomes in patients undergoing laparoscopic hysterectomy we were concerned about the limited number of investigations of this important topic.…”

“…Nazzaro et al [1] recently presented an interesting study about the possibility of using 2-dimensional (2D) and 3dimensional (3D) power Doppler technology in the differential diagnosis of septate and bicornuate uteri. We fully agree with the authors that Doppler analysis of congenital m€ ullerian anomalies may be an interesting tool for the study of vascular differentiation in the individual class of anomalies.…”

“…Washburn et al[1] have presented a fascinating outline of trends in reported resident surgical experience in hysterectomy. The trends are clear in their graph, even to the naked eye.…”

Tumor extent impacts survival benefit in minimally invasive colectomy for T4 colon cancer: A propensity matched national cohort analysis

“…Surgical resection is a curative‐intent treatment for the majority of patients with localized colon cancer, and like adjuvant chemotherapy, improves survival. Over the last three decades, minimally invasive techniques for colectomy (MC) have been rapidly adopted, beginning with the first description of laparoscopic colectomy in 1991 1 . Early and rapid adoption has been attributed to the improved short‐term recovery and quality of life with MC compared with open colectomy (OC) 2–4 ENREF 2.…”
