Method for transumbilical single-port extraperitoneal route lymph node excision

Abstract

The invention relates to a medical technology, and provides a transumbilical single-hole extraperitoneal route lymph node resection method, which comprises the following steps of: (1) selecting the upper part of an abdominal aorta intersection as a posterior peritoneal route operation entrance, penetrating a suture needle through a posterior peritoneum, and lifting the posterior peritoneum to a transumbilical single-hole incision; (2) after the retroperitoneal suspended suture is pulled to the transumbilical single-hole incision, suturing and reinforcing are carried out at a retroperitoneal operation entrance; (3) inserting a pneumoperitoneum needle into the sutured part in the step (2), injecting carbon dioxide gas, and separating a gap behind the peritoneum; then cutting off the suspension suture reserved in the step (1), opening a window behind the peritoneum to form an incision of 1-3 cm, inserting an incision protector, and installing a single-port laparoscopic surgery port on an incision protection sleeve; and (4) sequentially cutting internal and external iliac lymph nodes and obturator lymph nodes, and cutting lymph nodes beside aorta abdominalis. The lymph node excision method is simple and convenient to operate, and can be used for excising the lymph nodes more clearly without intestinal tract interference.

Description

A method of transumbilical single-port extraperitoneal lymph node dissection technical field The present invention relates to the technical field of medical technology, specifically, relate to a kind of extraperitoneal path lymph node through umbilical single hole method of knot excision. Background technique Laparoscopic lymphadenectomy has the effect of magnifying the surgical field by direct vision, and compared with laparotomy, it has the Accurate, minimally invasive, less bleeding, less complications, quicker postoperative recovery, etc., but the exposure of the vascular region, especially the high abdominal aorta The exposure of lymph nodes has always been a difficult but non-negligible problem. Para-aortic lymphadenectomy lymphade-nectomy, PAL) to determine whether there is lymph node metastasis in the para-aortic lymph nodes, and whether to supplement extended radiation after surgery Field irradiation is closely related and determines the final survival ra...

AI Technical Summary

Problems solved by technology

However, according to the results reported in the existing literature, because multi-hole laparoscopy can only enter the retroperitoneum through the lateral approach, although this approach solves the problem of horizontal para-aortic lymph node exposure and dissection, it is affected by the angle. However, the field of view of the pelvis is limited, and the range of pelvic lymph node resection cannot be exposed, which makes it difficult to expose and dissect the pelvic lymph nodes, which can be easily done by conventional surgery
