Objective

To describe the anatomy of pelvic autonomic nerves as it applies to nerve-sparing radical hysterectomy, and the technique, feasibility, and results of robotic nerve-sparing radical hysterectomy.

Methods

Prospective evaluation of 6 patients undergoing robotic nerve-sparing radical hysterectomy (type C1) for cervical cancer Stage IB (1B1 in 3 and 1B2 in 3 patients). Pelvic lymphadenectomy was performed in 3 patients and pelvic and aortic in the remaining 3 patients.

Results

The operation was completed in all patients. The mean age of the patients was 51.0 (range 33-73) and mean BMI 27.8 (range 23.2-35.1). The mean operating time was 238.6 min (range 207-256), mean blood loss 135 ml (range 100-150), mean number of lymph nodes was 23.6 (range 19-29), mean hospital stay was 2 days (range 1-4). There were no intraoperative complications. Postoperative complications occurred in 1 patient with an ileus who required an extended hospital stay. One patient did not regain normal urinary voidings until the fourth week after surgery. All patients remain free of disease.

Conclusion

Robotic nerve-sparing radical hysterectomy is safe and feasible. Urinary dysfunction may occur.  相似文献

Abstract. Trimbos JB, Maas CP, DeRuiter MC, Peters AAW, Kenter GG. A nerve-sparing radical hysterectomy: Guidelines and feasibility in Western patients.
Surgical damage to the pelvic autonomic nerves during radical hysterectomy is thought to be responsible for considerable morbidity, i.e., impaired bladder function, defecation problems, and sexual dysfunction. Previous anatomical studies and detailed study of surgical techniques in various Japanese oncology centers demonstrated that the anatomy of the pelvic autonomic nerve plexus permits a systematic surgical approach to preserve these nerves during radical hysterectomy without compromising radicality. We introduced elements of the Japanese nerve-preserving techniques and carried out a feasibility study in ten consecutive Dutch patients. The technique involved three steps: first, the identification and preservation of the hypogastric nerve in a loose tissue sheath underneath the ureter and lateral to the sacro-uterine ligaments; second, the inferior hypogastric plexus in the parametrium is lateralized and avoided during parametrial transsection; third, the most distal part of the inferior hypogastric plexus is preserved during the dissection of the posterior part of the vesico-uterine ligament. The clinical study showed that the procedure is feasible and safe, except possibly when used with very obese patients and patients with broad, bulky tumors. Surgical preservation of the pelvic autonomic nerves in radical hysterectomy deserves consideration in the quest to improve both cure and quality of life in cervical cancer patients.  相似文献

In 2002, our group introduced an operation to avoid damage to the pelvic autonomous nerves during radical hysterectomy that proved to be feasible, effective and safe. During the last five years, we have adapted our surgical technique to make this procedure easier and safer in terms of radicality. We report on the changes in the surgical approach and the results in the first 15 consecutive patients. The Swift operation is more radical in the area of the uterosacral ligaments than the original operation, and it dissects the hypogastric nerve free under direct vision. In the area of the parametria, it is more radical in the deep lateral part. The vascular parametrial tissue is dissected and separated ventrally from the ureters. From October 2006 to February 2007, 15 consecutive patients with cervical cancer stage IA2 to IB2 underwent the Swift operation. The extra operating time amounted to 20 min, which was similar to the original operation, and with no extra blood loss. The suprapubic catheter was removed after a median of five days. Up until now (February 2008), no recurrences have been seen in these patients. It was concluded that the Swift procedure is easy to perform and that it offers advantages over the original operation in terms of safety and radicality.  相似文献

Hysterectomy is one of the most frequently performed operations in the world, accounting for 500,000-600,000 procedures annually in the USA; the abdominal route for hysterectomy is the preferred route in 60-80% of these operations. Although the number of total abdominal hysterectomies performed annually has decreased, the number of subtotal abdominal hysterectomies increased by >400%. The major indications for abdominal hysterectomy include abnormal uterine bleeding, myomata uteri, adenomyosis, endometriosis, neoplasia, and chronic salpingitis. The basis for selection for subtotal versus total hysterectomy has little in the way of factual data to support it and may actually present some significant disadvantages, such as continued menstruation and cervical prolapse. The detailed technique for performing intrafascial abdominal hysterectomy relies heavily on precise knowledge of pelvic anatomy and compulsive detail to tissue handling. The consistent and correct usage of prophylactic antimicrobials, measures to prevent thromboemboli, and procedures to avoid urinary retention are key to the overall success of the surgery.  相似文献

BACKGROUND: Intestinal evisceration through the vagina is rare and transvaginal evisceration after transabdominal surgery is far more rare. CASE: We present an unusual case of a postmenopausal woman who presented with transvaginal evisceration of the small bowel after radical abdominal hysterectomy and pelvic lymphadenectomy. CONCLUSION: This was a rare case of terminal ileal evisceration through a ruptured vaginal cuff after radical hysterectomy and bilateral pelvic lymphadenectomy. We performed a delayed closure of the vaginal defect through the vagina after manual reduction of the eviscerated small bowel, and the outcome was satisfactory.  相似文献

Records of 35 patients with cervical cancer Stage IB operated with radical abdominal hysterectomy and pelvic lymphadenectomy were surveyed retrospectively for incidence of febrile morbidity and site-related infections. Febrile morbidity was observed in 6 patients (17%). No surgical site-related infections were observed. It is concluded that radical abdominal hysterectomy in our hospital does not carry any significant risk of postoperative site-related infections and that prophylactic antibiotics cannot be recommended.  相似文献

早期宫颈癌可能存在嗜神经侵袭(PNI)现象,PNI是影响宫颈癌预后的新的高危因素,保留神经可能有一定的潜在风险。这也是目前有关保留神经术式争议的焦点之一。研究宫颈癌PNI的目的在于完善宫颈癌保留神经手术(NSRH)的手术适应证,从而更好地体现该术式的优越性,并不是否定NSRH。PNI是影响NSRH适应证的主要因素之一,因此,明确NSRH的适应证很有必要而且是势在必行。  相似文献

OBJECTIVE: Nerve-sparing dissection of the lateral portion of the cardinal ligament (paracervical lymphadenectomy) has been recently developed with the goal of reducing the late urinary adverse effects of radical hysterectomy without impairing the outcome. This work has been carried out in order to investigate the influence of additional paracervical lymph node dissection at the time of laparoscopically assisted modified radical hysterectomy on outcome and urinary sequelae. METHODS: A total of 95 patients underwent a modified radical hysterectomy using a combined laparoscopic and vaginal approach since 1991. In 47 of these patients treated since 1996 an additional laparoscopic paracervical lymphadenectomy was performed. The operative, postoperative, and survival outcomes were assessed. In 60 patients, 32 and 28 in the groups of patients with or without paracervical dissection, respectively, a careful interview on urinary symptoms was conducted by an independent investigator. RESULTS: Paracervical dissection involves no operative complication and lenghthens the postoperative urinary retention, but has no adverse influence on long-term urinary discomfort. The yield of paracervical dissection is negligible for small tumors: no positive node was found in 38 patients with tumors less than 2 cm in diameter. The outcome of patients after minimal access surgery for tumors less than 2 cm is excellent whether or not a paracervical dissection has been performed. CONCLUSION: Paracervical dissection does not worsen the late urinary symptoms after vaginal radical hysterectomy. It has a limited value in the surgical management of small-size (less than 2 cm) cervical cancers, although it may prevent long-term lateropelvic recurrences.  相似文献

BACKGROUND: Autonomic nerve damage plays a crucial role in the etiology of bladder dysfunction, sexual dysfunction, and colorectal motility disorders that occur after radical hysterectomy. We investigated the extent and nature of nerve damage in conventional and nerve-sparing radical hysterectomy. METHODS: Macroscopical disruption of nerves was assessed through anatomical dissection after conventional and nerve-sparing surgery on five fixed and one fresh cadaver. Immunohistochemical analysis of surgical margins was performed to confirm nerve damage using a general nerve marker (S100) and a sympathetic nerve marker (anti-tyrosine hydroxylase) within sections of biopsies. RESULTS: Macroscopical dissection showed that in the conventional procedure, transsection of the uterosacral ligaments resulted in disruption of the major part of the hypogastric nerve. After nerve-sparing surgery, only the medial branches of the hypogastric nerve appeared disrupted. Division of the cardinal ligaments in the conventional procedure identified the inferior hypogastric plexus running into the most posterior border of the surgical margin. The anterior part of the plexus was disrupted. Dissection of the nerves after the nerve-sparing procedure showed that this anterior part of the plexus was not involved in the surgical dissection line. Dissection of the vesicouterine ligament disrupted only small nerves on the medial border of the inferior hypogastric plexus in both techniques. Microscopical evaluation of the surgical margins confirmed the macroscopical findings. CONCLUSION: Conventional radical hysterectomy results in disruption of a substantial part of the pelvic autonomic nerves. The nerve-sparing modification leads to macroscopic reduction in nerve disruption which is substantiated by microscopical evaluation of surgical margins.  相似文献
