ABSTRACT
Objective:To explore the clinical feasibility of extra-peritoneal laparoscopic radical cystectomy based on the concept of 3D membrane anatomy.Methods:The clinical data of 10 male patients with bladder cancer who underwent 3D extra-peritoneal laparoscopic radical cystectomy + ileal-orthotopic-neobladder surgery from October 2020 to June 2021 were retrospectively analyzed. The median age was 67 years. The ASA score was 1-2 in 8 cases and 3 in 2 cases. There were 4 cases of hypertension, 2 cases of diabetes, 1 case of heart disease, no case of abdominal surgery history. During the operation, the concept of 3D membrane anatomy was used to identify the important fascia in the pelvic cavity and to find the key layers and structures in the pelvic cavity.It was separated from the prevesical fascia to the laterovesical space, and confluenced with Retzius space and Bogros space. It was dissected in the layer surrounded by the prevesical fascia, the vesicohypogastric fascia, and the urogenital fascia to complete the process of cystectomy.Results:The operations of 10 patients were completed successfully and there was no conversion to open operation. The median operation time was 276(237-325) minutes, and the median blood loss was 160(50-280)ml. The postoperative bowel recovery median time was 1.8(1-3)days, and the patients were out of bed about 1.3(1-2) days. The median postoperative hospital stay was 9(5-12) days. The number of median lymph node dissection in all patients was 10(6-20). Positive lymph nodes was found in 3 cases. Positive margin was found in no case. Postoperative tumor pathological stages were T 2 stage in 7 cases, T 3 stage in 3 cases. During the follow-up, all patients had no obvious complications. Conclusions:It is feasible to apply the concept of 3D membrane anatomy to identify and locate the key fascia structures and levels in extra-peritoneal laparoscopic radical cystectomy. The operative complications were less and the postoperative recovery was faster. The anatomy is clear during the operation, which has good safety and reduces the difficulty of the operation.
ABSTRACT
Background: Since the advent of minimal access surgery, its application has been widespread starting from appendectomy to complex intestinal surgeries carried out laparoscopically. But hernia surgery is a major debatable section, to compare it with the commonly performed gold standard Lichtenstein repair. First laparoscopic transabdominal preperitoneal and then totally extra peritoneal (TEP) repair came into existence. In today’s era of extended TEP repair laparoscopic TEP repair has emerged to be gold standard.Methods: This is a prospective cohort study including 40 cases of Lichtenstein open meshplasty, against minimally invasive laparoscopic TEP procedure were compared. Patients operated in our department between January 2010 and September 2010 were included after consent and assessment. Procedures were carried out according to standard guidelines, and results compared for technical details, cosmesis, intra or post-operative complications, analgesia requirement, hospital stay, recovery and follow up and all results were analyzed.Results: Operative time was less by 2 minutes, hospital stay less by 1 day, return to work earlier by nearly 20 days for strenuous work, analgesia requirement less for laparoscopic extra peritoneal repair.Conclusions: Study showed that if the period of learning curve has been eliminated than an experienced surgeon performs laparoscopic procedure with better patient satisfaction, less hospital stay, faster recovery and earlier return to work with less operative time, analgesic consumption, and complication.
