Single-Incision Laparoscopic Ileal Pouch-Anal Anastomosis in Children—How Does It Compare to a Laparoscopic-Assisted Approach?

Initial experience with transanal proctectomy in children

BACKGROUND

The use of transanal proctectomy may have particular advantages for pediatric patients with small pelvic working space. We report short-term outcomes of transanal completion proctectomy (taCP) during surgery for inflammatory bowel disease.

METHODS

All patients (age≤19) underwent taCP from January 1, 2018 to December 31, 2019. Prior total abdominal colectomy (TAC) was performed using a single-incision technique. At operation, patients underwent single-incision laparoscopy with taCP. Patient demographics, pre and perioperative details, and postoperative complications were abstracted.

RESULTS

Seven patients (n = 6) with a median age of 18 years [Range: 13-19] were included in this initial series. All patients had a prior TAC with end-ileostomy with taCP occurring a median of 6 [Range: 3-89] months after TAC. Six of 7 had a diagnosis of ulcerative colitis (UC) while 1 patient had Crohn's colitis. For patients with UC, taCP was part of an ileal pouch-anal anastomosis with the majority (n = 4) proceeding as a modified-two stage and the remaining (n = 2) a three-stage approach. Single-incision laparoscopy through the prior ileostomy site was used in all IPAA patients. Median operative time was 226 [Range: 150-264] minutes with no conversions to more invasive technique. Median hospital length of stay (LOS) was 5 [Range: 2-8] days. In-hospital complications occurred in two patients who had watery diarrhea that prolonged LOS but resolved postdischarge. One patient was readmitted for bowel obstruction that resolved with placement of red rubber catheter at the ileostomy site. Of the 4 patients with a functioning ileal pouch, 1 patient reported 6-10 bowel movements per day, while 3 others reported ≤5 bowel movements per day. Half (n = 2) reported 1-2 nocturnal bowel movements at their first postoperative visit. No patients reported soiling or leakage, though one patient had a single episode of incontinence.

CONCLUSION

In this pilot series, transanal proctectomy was effective and safe. Future work should compare traditional MIS completion proctectomy to taCP for applications in pediatric inflammatory bowel disease.

The effect of diversion on readmission following ileal pouch-anal anastomosis in children

BACKGROUND

Readmission rates as high as 20% have been reported after ileal pouch-anal anastomosis (IPAA) in children, with obstruction and dehydration as the most commonly listed reasons. We hypothesized that a diverting ileostomy contributes to unplanned readmission after IPAA creation.

METHODS

Children (age <18) who underwent IPAA creation from January 2007 to August 2018 at two affiliated institutions were reviewed. Patient demographics, operative details, and post-operative length of stay (LOS) were abstracted. Unplanned readmission within 30 days and details on patient readmission were reviewed.

RESULTS

Ninety-three patients (57% female) with a median age of 15 years (range: 18 months-17 years) underwent IPAA. Indications for IPAA included ulcerative colitis (n = 63; 68%), familial adenomatous polyposis (n = 24; 26%), indeterminate colitis (n = 5; 5%), and total colonic Hirschsprung's (n = 1; 1%). Sixty-one (66%) patients were diverted at the time of IPAA creation. Fourteen patients (15%) were readmitted, and reasons for readmission included bowel obstruction (n = 9; 64%), dehydration (n = 2; 14%), anastomotic leak (n = 2; 14%), and gastrointestinal (GI) bleeding (n = 1; 6%). Patients with a diverting ileostomy at the time of IPAA were more often readmittted than patients who were not diverted (21% vs 3%, p = 0.03). Further, 10 (71%) of the readmitted patients had complications attributable to their ileostomy. In patients readmitted for obstructive symptoms, six (67%) required red rubber catheter insertion for resolution, two (22%) patients required reoperation for obstructions at the level of the stoma, and one (11%) resolved with bowel rest alone.

CONCLUSION

Readmission following IPAA creation in children is often secondary to preventable issues related to diverting ileostomy. Surgeons should carefully consider the necessity of diversion. When it is necessary, particular attention to fascial aperture size and post-discharge initiatives to reduce dehydration may reduce readmission rates.

Complications after proctocolectomy and ileal pouch-anal anastomosis in pediatric patients: A systematic review

BACKGROUND/PURPOSE

Colectomy with ileal pouch-anal anastomosis (IPAA) is the standard of care for patients with familial adenomatous polyposis (FAP) and refractory ulcerative colitis (UC). The rates of postoperative complications are not well established in children. The objective of this systematic review is to establish benchmark data for morbidity after pediatric IPAA.

METHODS

PubMed, Embase, and The Cochrane Library were searched for studies of colectomy with IPAA in patients ≤21 years old. UC studies were limited to the anti-tumor necrosis factor-α agents era (1998-present). All postoperative complications were extracted.

RESULTS

Thirteen studies met the inclusion criteria (763 patients). Compared to patients with FAP, UC patients had a higher prevalence of pouch loss (10.6% vs. 1.5%). Other major complications such as anastomotic leak, abscess, and fistula were uncommon (mean prevalence 4.9%, 4.2%, and 5.0%, respectively, for patients with UC; 8.7%, 4.2%, and 4.3% for FAP). The most frequent complication was pouchitis (36.4% of UC patients).

CONCLUSIONS

Devastating complications from colectomy and IPAA are rare, but patients with UC have poorer outcomes than those with FAP. Much of the morbidity may therefore stem from patient or disease factors. Multicenter, prospective studies are needed to identify modifiable risks in patients with UC undergoing IPAA.

Ileal-pouch anal anastomosis in pediatric NSQIP: Does a laparoscopic approach reduce complications and length of stay?

PURPOSE

The purpose of this study was to determine if a laparoscopic approach reduces complications and length of stay (LOS) after total proctocolectomy with ileal pouch-anal anastomosis (TPC-IPAA) in pediatric patients using a multicenter prospective database.

METHODS

The American College of Surgeons National Surgical Quality Improvement Project Pediatric database from 2012 to 2015 was used to identify patients with a diagnosis of chronic ulcerative colitis (CUC) or familial adenomatous polyposis (FAP) undergoing TPC-IPAA. Major complications, minor complications, and prolonged LOS were compared based on laparoscopic versus open approach.

RESULTS

195 (108 female) patients underwent TPC-IPAA at a median age of 14 years (IQR: 11-16) for CUC (N = 99) or FAP (N = 96). Two-thirds of cases were laparoscopic. A laparoscopic approach was not associated with major complications, but lower odds of minor complications were observed. A reduced LOS was seen in laparoscopic versus open surgery (median LOS 6 vs 8 days, p < 0.01). Open IPAA was independently associated with prolonged LOS (>9 days) in the FAP cohort (OR 4.0, 95% CI 1.1-14.0).

CONCLUSION

A laparoscopic approach was not associated with increased major complications but was associated with lower odds of minor complications and shorter LOS. The laparoscopic approach should continue to be preferred for pouch procedures in pediatric patients.

Complications in children with ulcerative colitis undergoing ileal pouch-anal anastomosis

Total colectomy with ileal pouch-anal anastomosis (IPAA) is considered the standard procedure for the surgical management of ulcerative colitis. Despite the widespread utility of the procedure, as many as 75% of patients who undergo IPAA, experience at least 1 complication. This review highlights difficult intraoperative scenarios and complications of pouch surgery in children, including intraoperative, postoperative, and functional complications. Intraoperative scenarios include insufficient mesenteric length and positive leak tests. Postoperative complications include surgical site infection, anastomotic leak, stricture, fistula, pouchitis, small bowel obstruction, and pouch failure. Less common complications include afferent limb syndrome, pouch prolapse, and superior mesenteric artery syndrome. Functional complications include incontinence, impaired quality of life, infertility, and sexual dysfunction. Despite complications, most patients are satisfied with their outcomes and report an improvement in their lifestyle.

Early Experience with Single-Incision Laparoscopic Total Abdominal Colectomy in Children

PURPOSE

Single-incision laparoscopic surgery for pediatric colorectal disease has been shown to be feasible and safe; however, the literature is scarce regarding the outcomes of single-incision laparoscopic total abdominal colectomy (SIL-TAC) in the pediatric population. The purpose of this pilot study was to review our initial experience and outcomes with SIL-TAC.

MATERIALS AND METHODS

A retrospective review of patients who underwent SIL-TAC from 2013 to 2015 was performed. General demographic and outcome data were analyzed.

RESULTS

Five patients were included. Indications included ulcerative colitis (n = 4) and colonic dysmotility (n = 1). The median age was 13.5 years (8.5-19.4 years) and the median body mass index (BMI) percentile was 77.4 (2.2-98). The median operative time was 182 minutes (163-244 minutes). One case was converted to an open procedure. The median postoperative self-reported pain score was 2.8 (1.2-4.5). The median time until initiation of a diet was 2 days (1-8 days). The median length of hospital stay was 5 days (3-11 days). There were no 30-day complications.

CONCLUSION

SIL-TAC is feasible and safe in children and offers improved cosmesis.

Initial experience of restorative proctocolectomy for ulcerative colitis by transanal total mesorectal rectal excision and single-incision abdominal laparoscopic surgery

AIM

Laparoscopic surgery is well established for colon cancer, with defined benefits. Use of laparoscopy for the performance of restorative proctocolectomy (RPC) with ileoanal anastomosis is more controversial. Technical aspects include difficult dissection of the distal rectum and a potentially increased risk of anastomotic leakage through multiple firings of the stapler. In an attempt to overcome these difficulties we have used the technique of transanal rectal excision to perform the proctectomy. This paper describes the technique, which is combined with an abdominal approach using a single-incision platform (SIP).

METHOD

Data were collected prospectively for consecutive operations between May 2013 and October 2015, including all cases of restorative proctocolectomy with ileoanal pouch anastomosis performed laparoscopically. Only patients having a transanal total mesorectal excision (TaTME) assisted by SIP were included. The indication for RPC was ulcerative colitis (UC) refractory to medical treatment.

RESULTS

The procedure was performed on 16 patients with a median age of 46 (26-70) years. The male:female ratio was 5:3 and the median hospital stay was 6 (3-20) days. The median operation time was 247 (185-470) min and the overall conversion rate to open surgery was 18.7%. The 30-day surgical complication rate was 37.5% (Clavien-Dindo 1 in four patients, 2 in one patient and 3 in one patient). One patient developed anastomotic leakage 2 weeks postoperatively.

CONCLUSION

This initial study has demonstrated the feasibility and safety of TaTME combined with SIP when performing RPC with ileal pouch-anal anastomosis for UC.

Transanal completion proctectomy after total colectomy and ileal pouch-anal anastomosis for ulcerative colitis: a modified single stapled technique

AIM

Minimally invasive surgery has proved its efficacy for the surgical treatment of ulcerative colitis (UC). The recent evolution in single port (SP) surgery together with transanal rectal surgery could further facilitate minimally invasive surgery in UC patients. This technical note describes a technical modification for single stapled anastomoses in patients undergoing transanal completion proctectomy and ileal pouch-anal anastomosis (ta-IPAA) for UC.

METHODS

A step-by-step approach of the ta-IPAA in UC is described, including pictures and a video illustration.

RESULTS

We describe a ta-IPAA with SP laparoscopy at the ileostomy site. All patients underwent a total colectomy with end-ileostomy for therapy refractory UC in a first step. Colectomy was done by multiport laparoscopy in six patients, while the ileostomy site was used as single port access in five patients. In all 11 patients the stoma site was used for SP mobilization of the mesenteric root and fashioning of the J-pouch. Completion proctectomy was done using a transanal approach. A single stapled anastomosis was performed in all patients. An 18 French catheter was used to approximate the pouch to the rectal cuff.

CONCLUSION

A technical modification of the single stapled anastomosis facilitates the formation of the ta-IPAA, further reducing invasiveness in UC patients.

Risk-reduction surgery in pediatric surgical oncology: A perspective

OBJECTIVE

A small percentage of pediatric solid cancers arise as a result of clearly identified inherited predisposition syndromes and nongenetic lesions. Evidence supports preemptive surgery for children with genetic [multiple endocrine neoplasia type 2 (MEN2), familial adenomatous polyposis syndrome (FAP), hereditary nonpolyposis colorectal cancer (HNPCC), and hereditary diffuse gastric cancer (HDGC) and nongenetic [thyroglossal duct cysts (TGDC), congenital pulmonary airway malformations (CPAM), alimentary tract duplication cysts (ATDC), and congenital choledochal cysts (CCC)] developmental anomalies. Our aim was to explore the utility of risk reduction surgery to treat and prevent cancer in children.

METHODS

A systematic review of the available peer-reviewed literature on PubMed was performed using a PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) search strategy, where possible. Search items included "risk reduction surgery", "hereditary cancer predisposition syndrome", "multiple endocrine neoplasia type 2", "familial adenomatous polyposis", "hereditary nonpolyposis colorectal cancer", "hereditary diffuse gastric cancer", "thyroglossal duct cysts", congenital pulmonary airway malformations", "alimentary tract duplication cysts", "malignant transformation", and "guidelines".

RESULTS

We identified 67 articles that met the inclusion criteria describing the indications for prophylactic surgery in surgical oncology. For the genetic predisposition syndromes, 7 studies were related to professional endorsed guidelines, 7 were related to surgery for MEN2, 11 were related to colectomy for FAP, 6 were related to colectomy for HNPCC, and 12 related to gastrectomy for HDGC. Articles for the nongenetic lesions included 5 for techniques related to TGDC resection, 9 for surgery for CPAMs, and 10 for resection of ATDCs. Guidelines and strategies varied significantly especially related to the extent and timing of surgical intervention; the exception was for the timing of thyroidectomy in children with MEN2.

CONCLUSION

Current evidence supporting prophylactic surgery in the management of pediatric cancer predisposition syndromes and nongenetic lesions is best delineated for thyroidectomy to prevent medullary thyroid cancer in children with MEN2 (Strength of Recommendation Grade B/C). Despite the lack of pediatric specific evidence-based recommendations regarding the appropriate extent and timing for risk-reduction surgery for FAP, HNPCC, HDGC and nongenetic anomalies, our review represents an opportunity towards understanding the postgenomic development of these lesions and provides current indications and techniques for preemptive cancer prevention surgery in children.
