METHODS OF CREATING PNEUMOPERITONEUM : A REVIEW OF TECHNIQUES AND COMPLICATIONS

The existence of numerous techniques for the creation of pneumoperitoneum at laparoscopy indicates that none have been proven totally efficacious or complication free. These methods include the standard technique of insufflation after insertion of the Veress needle via the umbilicus or less commonly via the transfundal or transforniceal routes, open laparoscopy involving dissection through the linea alba and opening of the peritoneum under direct vision, and direct trocar insertion as well as variations on these techniques. After reviewing the methods available and surveying the existing data concerning the rates of failure and complications, we conclude that no single technique can claim to be overwhelmingly superior, and that laparoscopists should, therefore, acquaint themselves with at least two of these techniques. Finally, we recommend a large-scale combined survey by the colleges of obstetricians and gynecologists and surgeons on rates of failure and complications of the varied approaches of abdominal entry for laparoscopy.

Home Within 24 Hours of Laparoscopic Hysterectomy

We assessed the feasibility of safe discharge home within 24 hours following laparoscopic hysterectomy in 30 patients who met the inclusion criteria and consented to be enrolled in the study group. Patients were admitted on the day of their surgery with the expectation of discharge within 24 hours. Appropriate home nursing follow‐up and phone contact by the surgical team were organized preoperatively. Inclusion criteria were: age 30–65 years, absence of any major medical history that would require prolonged hospitalization, availability of home support for the first 48 hours after discharge and presence of a working telephone line and an address within the area of the Community Home Nursing service. All 30 operative procedures were completed without incident. Six patients underwent total laparoscopic hysterectomy (TLH) (all the procedures of hysterectomy being performed laparoscopically including the suturing of uterine arteries, colpotomy and closure of the vaginal vault. The uterus was removed vaginally) and 24 patients underwent laparoscopic hysterectomy (LH) (this techniques differs from TLH in that the colpotomy was performed laparoscopically but the uterosacral ligaments were divided vaginally and the vault also was closed vaginally after the uterus was removed vaginally). The average operating time was 115 minutes (range 85–150 minutes) and the average blood loss was 97 mL (20–250 mL). There were no intraoperative complications, no requirement for transfusion and no readmission to hospital for any of the patients in the study. Postoperative complications were minor (umbilical cellulitis (1), intestinal colic (1)) and both were treated with resolution of the symptoms. Ninety per cent of patients in the study were discharged within 24 hours of their surgery, the average duration of stay being 22.9 hours (20–24 hours). Three patients were not fit for discharge at 24 hours postoperatively due to general lethargy, migraine and nausea; their average discharge time was 53.5 hours. The study showed that laparoscopic hysterectomy can be associated with a reduction in length of in‐patient stay compared to traditional laparotomy. Furthermore this reduction could be safely reduced to 24 hours following laparoscopic hysterectomy. There was also an associated cost saving in terms of inpatient bed days. Patient satisfaction with this protocol was high in this selected and motivated group.

Laparoscopic or Transanal Repair of Rectocele? A Retrospective Matched Cohort Study

PURPOSEThe aim of the study was to analyze the functional and physiologic outcome of patients undergoing laparoscopic rectocele repair compared to a matched cohort undergoing transanal repair.METHODSForty patients with a rectocele who had undergone laparoscopic pelvic floor repair by a laparoscopic gynecologist were matched for age and rectocele size with 40 patients who had undergone a transanal repair by a colorectal surgeon. All patients had clinical evidence of a symptomatic rectocele. All patients were assessed postoperatively with a quality of life (SF-36) score, a modified St. Mark’s continence score, a urinary dysfunction score, a Watt’s sexual dysfunction score, and a linear analog patient satisfaction score. Fifteen patients in each group had also undergone preoperative and postoperative anal manometry.RESULTSAt 44 months median follow-up, the transanal approach resulted in significantly more patients reporting bowel symptom alleviation (P < 0.002) and higher patient satisfaction (P < 0.003). The bowel symptom improvement was also sustained over a significantly longer period (P < 0.03). Only 11 patients (28 percent) in the laparoscopic group reported more than 50 percent improvement in their bowel symptoms compared to 25 patients (63 percent) in the transanal group. On univariate analysis of 50 percent bowel symptom improvement, a larger rectocele (P < 0.009), transanal repair (P < 0.02), and presenting with obstructive defecation rather than fecal incontinence (P < 0.03) were statistically significant. Rectocele size (P < 0.012) and treatment cohort (P < 0.006) remained significant on multivariate analysis. Postoperatively, bowel symptom alleviation correlated with patient satisfaction in both groups (P < 0.015). Although not statistically significant, five patients (13 percent) in the transanal group developed postoperative fecal incontinence, which was associated with a low maximum anal resting pressure preoperatively that was further diminished postoperatively (P > 0.06). Only one patient (3 percent) in the laparoscopic group reported a decline in fecal continence, but four patients (10 percent) reported worsening of their symptoms of obstructed defecation. Postoperative dyspareunia was reported by 24 patients in total (30 percent), with significantly more in the transanal group (P > 0.05).CONCLUSIONSThe transanal repair results in a statistically greater alleviation of bowel symptoms and greater patient satisfaction scores. However, this approach may have a greater degree of functional co-morbidity than the laparoscopic rectocele repair.

Deeply Infiltrating Endometriosis: Implications, Diagnosis, and Management

Deeply infiltrating endometriosis was described in the early part of the last century. Only recently, has there become a greater awareness and understanding of this form of endometriosis aided in part by advances in laparoscopic surgical technology in techniques. The clinical implications of the disease as well as diagnosis and current management are reviewed. Target Audience: Obstetricians & Gynecologists, Family Physicians Learning Objectives: After completion of this article, the reader will be able to describe the pathologic features of deeply invasive endometriosis, to list the implications of deeply invasive endometriosis, and to outline treatment options for deeply invasive endometriosis.

Laparoscopic presacral neurectomy: a review.

Dysmenorrhea can be a severe and debilitating symptom in many women. Although most women may find adequate relief of symptoms from pharmacological approaches, there remain a few with resistant pain. Presacral neurectomy, although technically challenging, may be offered after other approaches are unsuccessful. The operation is now performed increasingly by the laparoscopic approach, which has revived this operation in some centers. The anatomy, technique, and indications as well as a review of the literature supporting this operation are reviewed. The potential complications of this operation are discussed also. Target Audience: Obstetricians & Gynecologists, Family Physicians Learning Objectives: After completion of this article, the reader will be able to explain the evolution of presacral neurectomy, define the anatomy of the autonomic nerves of the pelvis, list the indications for presacral neurectomy, and summarize the data surrounding the presacral neurectomy operation.

Bowel, bladder and sexual function in women undergoing laparoscopic posterior compartment repair in the presence of apical or anterior compartment dysfunction.

Objective: The aim of the study was to analyse the functional outcome of women undergoing a laparoscopic posterior compartment repair in the presence of anterior or apical compartment dysfunction.

Laparoscopic management of a case of abdominal ectopic pregnancy.

The aim of this study was to review the functional and psychological outcomes of subjects with vaginal apla- sia undergoing a laparoscopic creation of a neovagina (Vecchietti procedure). A semi-structured telephone interview was undertaken of five consecutive subjects who underwent the procedure in the preceding three years. Information was obtained with regard to the operation, immediate post-operative period, complica- tions experienced, sexual function and improvements in general and psychological well-being. A functioning neovagina was formed in all sub- jects. All sexually active women noted satisfactory intercourse with significant improvements in self-con- fidence, self-esteem and general well-being up to three years post-operatively.

The Safety of Laparoscopic Treatment for Ovarian Dermoid Tumours

Summary: Whilst laparoscopic surgery has largely replaced laparotomy as the standard surgical option for the management of benign ovarian cysts, concern remains regarding the safety of laparoscopy for benign cystic teratomas. This is based on a higher rate of cyst content spillage compared to laparotomy and the known sequelae of chemical peritonitis and granuloma formation. We present 18 cases of laparoscopic dermoid cystectomy with recommendations for specimen removal from the peritoneal cavity. Our findings together with evidence from the literature confirms the safety of laparoscopy for the treatment of ovarian dermoid cysts.
