Laparoscopic Swenson procedure - An optimal approach for both primary and secondary pull-through for Hirschsprung's disease

Background/Purpose: Several pull-through procedures are available for the surgical management of Hirschsprung's disease (HD) in children. The authors have adopted a laparoscopic approach since 1995, including laparoscopic Swenson procedure (LSw), both for one-stage primary and 2-stage secondary procedures. The aim of this study was to examine the role of LSw in children with HD in both primary and secondary procedures. Methods: From January 1995 to December 2001, 42 children with biopsy-proven HD underwent laparoscopic pull-through procedure for HD. This group included 29 children who underwent LSw, a detailed analysis of which forms the basis of this report. Results: Sixteen children underwent a single-stage neonatal LSw; the median weight of this group at the time of surgery was 3.2 kg and the median age was 5 days. Secondary LSw was performed in the remaining 13 children, which included 3 children with total colonic HD who underwent laparoscopic total colectomy and LSw. The median operating time was 105 minutes (range, 66 to 175 minutes). The median time to commence full diet was 48 hours (range, 24 to 86 hours), and median time to return to normal play and activity was 72 hours (range, 48 hours to 5 days). There was no difference in operating time between primary and secondary pull-through procedures. There were no intraoperative complications, and no patient required open conversion. Postoperative ileus was noted in 3 children and enterocolitis in 2. The median hospital stay was 4 days (range, 2 to 6 days). Follow-up was between 6 months to 7 years with a median follow-up of 2.2 years. At follow-up, 2 children required laparoscopic antegrade continence enema procedure. A satisfactory continence was noted in 15 of the 19 children who were older than 3 years at the time of last follow-up. Conclusions: LSw seems to be a suitable procedure for laparoscopic management of HD in children. LSw is safe and effective, both for primary and secondary type of pull-through procedures, with good short-term results.

Selective approach for transperitoneal and extraperitoneal endoscopic nephrectomy in children

Purpose: From the experience of a large combined series of transperitoneal. (TP) and retroperitoneal (RP) endoscopic complete and partial nephroureterectornies in children, we present a logical selective endoscopic approach to benign renal pathology. Materials and Methods: During a 5-year period 122 complete nephrectomies and nephroureterectomies (bilateral 2, invisible ectopic 8) and 63 partial nephroureterectomies for duplex (52 upper, 8 lower) or singleton polar disease (xanthogranulomatous pyelonephritis 1, cyst 2) were performed. Of the partial nephrectomies, ureterectomy, bladder repair and lower moiety reimplantation were performed in 8. Patient age ranged from 2.7 months to 14 years (mean 2.9 years). Preoperative weight ranged from 2.7 to 98 kg (mean 12.3). The position of the renal remnant, the presence or absence of a refluxing ureter and the need for ureterectomy were the major determining factors affecting choice of endoscopic approach. Results: A total of 179 (96.7%) procedures were successfully completed endoscopically. The 6 open conversions (3.2%) occurred early in our experience. The operating time reflected the complexity of the excision and lower urinary reconstruction (lateral and posterior RP 25 to 145 minutes [mean 921) TP with ureterocelectomy and bladder neck repair 105 to 355 minutes [mean 153]. Hospital stay for RP and simple TP was 1.5 days (mean 1 to 4) and for complicated TP 2 to 8 days (mean 3.5). Conclusions: We suggest a posterior retroperitoneal approach with isolated renal excision without extended ureterectomy. The lateral retroperitoneal approach allows complete ureterectomy as well as better exposure to horseshoe and pelvic kidneys and, therefore, avoids exposure to intraperitoneal. structures. Finally, the transperitoneal approach is recommended when complete moiety excision with lower urinary reconstruction is anticipated.

Postoperative analgesic requirements - total laparoscopic hysterectomy versus vaginal hysterectomy

Background: There is limited information available on the requirement for postoperative analgesic drugs in patients submitted to total laparoscopic hysterectomy (TLH) compared with patients undergoing vaginal hysterectomy (VH). Aim: To compare the postoperative analgesic requirements in patients who underwent a TLH with patients who had a VH. Methods: Chart review of 53 patients who had TLH and 47 who had VH and were seen postoperatively by an acute pain management service in order to assess postoperative analgesic requirements. Patient controlled analgesia (PCA) was part of the standard protocol for postoperative pain management. Analgesic requirement was recorded as the mean doses of morphine and number of days that patients used non-steroidal anti-inflammatory drugs (NSAIDs), oxycodone and tramadol. Results: The requirement for total morphine was approximately half the dose in patients who had a TLH (10.8 +/- 12.6 mg) compared with patients who had a VH (19.4 +/- 21.9 mg) (P 0.017). The length of use of NSAIDs was significantly reduced in patients who had undergone a TLH (2.0 +/- 0.95 days) as compared with patients who had a VH (2.85 +/- 1.1 days) (P < 0.0001). Conclusions: Patients submitted to TLH require less postoperative analgesic drugs when compared with patients who had VH. Prospective randomised trials are warranted to compare analgesic requirements between patients submitted to TLH and VH.

Laparoscopically-assisted resection rectopexy for rectal prolapse: Ten years' experience

PURPOSE: This study has been undertaken to audit a single-center experience with laparoscopically-assisted resection rectopexy for full-thickness rectal prolapse. The clinical Outcomes and long-term results were evaluated. METHODS: The data were prospectively collected for the duration of the operation, time to passage of flatus postoperatively, hospital stay, morbidity, and mortality. For follow-up, patients received a questionnaire or were contacted. The data were divided into quartiles over the study period, and the differences in operating time and length of hospital stay were tested using the Kruskal-Wallis test. RESULTS: Between March 1992 and October 2003, a total of 117 patients underwent laparoscopic resection rectopexy for rectal prolapse. The median operating time during the first quartile (representing the early experience) was 180 minutes compared with 110 minutes for the fourth quartile (Kruskal-Wallis test for operating time = 35.523, 3 df, P < 0.0001). Overall morbidity was 9 percent (ten patients), with one death (< 1 percent). One patient had a ureteric injury requiring conversion. One minor anastomotic leak Occurred, necessitating laparoscopic evacuation of a pelvic abscess. Altogether, 77 patients were available for follow-up. The median follow-up was 62 months. Eighty percent of the patients reported alleviation of their symptoms after the operation. Sixty-nine percent of the constipated patients experienced an improvement in bowel frequency. No patient had new or worsening symptoms of constipation after Surgery. Two (2.5 percent) patients had full-thickness rectal prolapse recurrence. Mucosal prolapse recurred in 14 (18 percent) patients. Anastomotic dilation was performed for stricture in five (4 percent) patients. CONCLUSIONS: Laparoscopically-assisted resection rectopexy for rectal prolapse provides a favorable functional outcome and low recurrence rate. Shorter operating time is achieved with experience. The minimally invasive technique benefits should be considered when offering rectal prolapse patients a transabdominal approach for repair, and emphasis should now be on advanced training in the laparoscopic approach.
