Transumbilical single-incision laparoscopic ileocecal resection for Crohn's disease in a child

Therapeutic strategies for stricturing Crohn’s disease in childhood: a systematic review

PURPOSE

Childhood stricturing Crohn's disease (CD) has significant morbidity. Interventions including resection, stricturoplasty and endoscopic balloon dilatation (EBD) are often required. Optimal intervention modality and timing, and use of adjuvant medical therapies, remains unclear. We aim to review the therapies used in paediatric stricturing CD.

METHODS

A systematic review in accordance with PRISMA was performed (PROSPERO: CRD42020164464). Demographics, stricture features, interventions and outcomes were extracted.

RESULTS

Fourteen studies were selected, including 177 patients (183 strictures). Strictures presented at 40.6 months (range 14-108) following CD diagnosis. Medical therapy was used in 142 patients for an average of 20.4 months (2-36), with a complete response in 11 (8%). Interventions were undertaken in 138 patients: 53 (38%) resections, 39 (28%) stricturoplasties, and 17 (12%) EBD. Complications occurred in 11% of resections, versus 15% stricturoplasties, versus 6% EBD (p = 0.223). At a median follow-up of 1.9 years (interquartile range 1.2-2.4) pooled stricture recurrence was 22%. Resection had 9% recurrence, versus 38% stricturoplasty, versus 47% EBD (p < 0.001).

CONCLUSIONS

Resection is associated with a low incidence of recurrence and complications. There remains a paucity of evidence regarding adjuvant medical therapy and the role of EBD. We propose a minimum reported dataset for interventions in paediatric stricturing CD.

Success of Minimally Invasive Transumbilical Single-Incision Laparoscopic Surgery (T-SILS) Plus Double-Balloon Endoscopy (DBE) for Pediatric Intestinal Angiodysplasia: A Case Report

We describe here a child with angiodysplasia of the small intestine, diagnosed by double-balloon endoscopy (DBE), who was treated with transumbilical single-incision laparoscopic surgery (T-SILS). A 9-year-old boy presented to another hospital with intermittent fresh melena of a duration of 5 months and 4 days. Anoscopy and gastric mucosal membrane scintigraphy were unsuccessful diagnostically, and he was referred to our hospital for further examination and treatment. Under general anesthesia, we performed DBE by an anal route, with the ileum assessed for a distance of about 150 cm from the ileocecal valve. Although no bleeding lesion was found in the colon, a flat elevated venous lake approximately 20 mm in size was observed 20 cm from the ileocecal valve, suggesting angiodysplasia of the small intestine. A tattoo was made under DBE, and wedge resection by T-SILS was performed 1 month later under general anesthesia. The excised specimen appeared as a flat, elevated venous lake approximately 20 mm in size. Histopathologic analysis revealed several dilated and distorted veins within the submucosa of the small intestine. The patient was diagnosed with angiodysplasia of the small intestine. His postoperative course was uneventful, and he remained free of recurrent gastrointestinal bleeding 18 months after the operation. This is the first case report showing the diagnosis, localization, and tattooing of an obscure gastrointestinal bleeding lesion of the small intestine by preoperative DBE and removal of the lesion by subsequent T-SILS in children.

Single-incision laparoscopic surgery (SILS) for children with Crohn's disease

PURPOSE

Single-incision laparoscopic surgery (SILS) has been described in adults with Crohn's disease, but its use in pediatric Crohn's patients has been limited. The purpose of this study was to review our experience with SILS in pediatric patients with Crohn's disease.

METHODS

A retrospective review was performed for patients diagnosed with Crohn's disease who underwent small bowel resection or ileocecectomy at a freestanding children's hospital from 2006 to 2014. Data collected included demographic data, interval from diagnosis to surgery, operative time, length of stay, and postoperative outcomes.

RESULTS

Analysis identified 19 patients who underwent open surgery (OS) and 41 patients who underwent SILS. One patient (2.4 %) within the SILS group required conversion to OS. Demographic characteristics were similar between the 2 cohorts. The most common indication for surgery was stricture/obstruction (SILS 70.7 % vs. OS 68.4 %, p = 0.86), and ileocecectomy was the most common primary procedure performed (SILS 90.2 % vs. OS 100 % OS). Operative times were longer for SILS (135 ± 50 vs. 105 ± 37 min, p = 0.02). However, when the last 20 SILS cases were compared to all OS cases, the difference was no longer statistically significant (SILS 123.3 ± 34.2 vs. OS 105 ± 36.5, p = 0.12). No difference was noted in postoperative length of stay (SILS 6.5 ± 2.2 days vs. OS 7.4 ± 2.2 days, p = 0.16) or overall complication rate (SILS 24.4 % vs. OS 26.3 %, p = 0.16).

CONCLUSION

SILS ileocecectomy is feasible in pediatric patients with Crohn's disease, achieving outcomes similar to OS. As experience increased, operative times also became comparable.

The international experience of single-incision pediatric endosurgery: current state of the art

PURPOSE

As application and awareness of single-incision pediatric endosurgery (SIPES) are increasing, various techniques and indications have been independently described by select centers around the world. In order to facilitate a cooperative approach toward advancing and investigating the practice of SIPES, we conducted a survey among members of the International Pediatric Endosurgery Group (IPEG), asking them about their experience and attitudes toward single-incision endosurgery.

MATERIALS AND METHODS

After institutional review board approval, an invitation to participate in an online survey was sent to all IPEG members. Questions focused on demographic information, practice patterns, indications, and equipment used regarding SIPES.

RESULTS

Of the 560 contacted active IPEG members, 115 completed the survey (recall 21%). The respondents represented pediatric surgeons from 32 countries on six continents. Of respondents, 97% had heard of, while 71% had performed, SIPES. Reasons for not having performed SIPES included disbelief in benefit (59%), lack of proficiency (34%), and inadequate resources (28%). The most commonly performed SIPES procedures were appendectomy (85%), cholecystectomy (66%), splenectomy (42%), pyloromyotomy (35%), and intestinal surgery (13%), as well as Nissen fundoplication and gynecologic adnexal pathology (7%). The equipment and techniques utilized showed large variation and included some self-devised, innovative, low-resource approaches. Complications with SIPES reported by the survey participants included technical difficulties, wound infection, and prolonged operating time.

CONCLUSIONS

SIPES is being performed worldwide for a large spectrum of common indications in pediatric surgery. The equipment and techniques used vary with geographic location and resources. Some encountered complications are common to those seen with conventional minimally invasive surgery, whereas others may be SIPES-specific. Different respondents reported diverging views on pain, operating time, and cost.
