Laparoscopic-assisted transanal pull-through for Hirschsprung's disease: Comparison between partial and near total laparoscopic mobilization of rectum

Transanal Endorectal Pull-Through for Hirschsprung's Disease: Complications and Lessons from Our Practice and the Literature

BACKGROUND/OBJECTIVES

Hirschsprung's disease (HD) is a congenital disorder characterised by the absence of ganglion cells in the distal bowel, resulting in functional obstruction. The transanal endorectal pull-through (TEPT) procedure, a minimally invasive approach, aims to treat HD by removing the aganglionic segment. This study assessed the feasibility, safety, and efficacy of single-stage TEPT in paediatric patients, focusing on postoperative complications, bowel function, and quality of life.

METHODS

A retrospective cohort study was conducted on 150 children who underwent single-stage TEPT from January 2005 to December 2023 at the Medical University of Gdansk. Data were collected from medical records, including demographics, preoperative assessments, surgical details, postoperative management, and follow-up outcomes. Statistical analyses were performed using Microsoft Excel 365 and the programming language Python 3.12. The mean age at surgery was 13 months, with a male-to-female ratio of 2.75:1. The mean operative time was 129 min, and the mean hospital stay was seven days.

RESULTS

Postoperative complications included anastomotic leak (4%), wound infections (15%), and enterocolitis (26%). Redo surgeries were required in 18% of cases due to persistent constipation and obstructive symptoms. This article includes a comprehensive review of the literature.

CONCLUSIONS

TEPT demonstrates a favourable safety profile and efficacy in treating HD, though significant concerns include complications such as enterocolitis and the need for additional surgeries. Surgical expertise and thorough preoperative and postoperative management are crucial to optimising patient outcomes.

Minimally Invasive Surgery for Hirschsprung Disease: Current Practices and Future Directions

Hirschsprung disease (HD) is a congenital disorder characterized by the absence of ganglion cells in the distal colon and rectum, leading to functional obstruction and severe constipation. Over the past decades, the surgical management of HD has significantly evolved, with minimally invasive surgery (MIS) techniques revolutionizing treatment approaches. This review explores recent innovations in MIS for HD, focusing on laparoscopic, transanal endorectal pull-through (TERPT), and robotic-assisted techniques. These approaches offer numerous advantages over traditional open procedures, including reduced surgical trauma, improved cosmesis, faster recovery times, and potentially lower complication rates. Laparoscopic surgery has become widely adopted, providing excellent visualization and precise dissection. TERPT has gained popularity for short-segment disease, offering a completely transanal approach with minimal scarring. Robotic-assisted surgery represents the cutting edge, enhancing surgical precision and dexterity. The review also examines emerging technologies and future directions, such as advanced imaging techniques, artificial intelligence applications, and potential developments in tissue engineering. While MIS techniques have shown promising outcomes, challenges remain in standardizing approaches, addressing long-segment disease, and optimizing long-term functional results. The future of HD surgery lies in personalized approaches that integrate genetic and molecular profiling with advanced surgical technologies. As the field continues to evolve, comprehensive long-term studies and efforts to improve access to specialized care will be crucial to further enhancing outcomes for patients with HD.

Comparison between two minimally invasive techniques for Hirschsprung disease: transanal endorectal pull-through (TERPT) versus laparoscopic-TERPT

INTRODUCTION

Surgical treatment for Hirschsprung disease (HD) has recently evolved into different minimally invasive techniques. The aim of the present study is to compare results from two different minimal invasive approaches, transanal endorectal pull-through (TERPT) and laparoscopic-assisted endorectal pull-through (LA-TERPT).

METHODS

Patients have been divided into two groups according to surgical technique. Data of HD patients treated by TERPT and those treated by LA-TERPT, respectively, performed at two different centers from January 2007 to December 2017, were retrospectively collected. Patients with aganglionosis confined to the recto-sigmoid colon with a minimum follow-up period of 4 years have been included. Demographic, clinical, surgical and functional outcome data were reviewed for each group using Chi-square and Fisher tests (statistical differences were considered for p < 0.05).

RESULTS

Among patients treated for HD in the two centers during the study period, 65 met the inclusion criteria (37 TERPT group and 28 LA-TERPT group). No differences regarding demographic and clinical data were observed between the two groups. Operative time was longer in the LA-TERPT group (p < 0.001). Time to start oral feeding was faster in the TERPT group while hospital stay was similar between the two groups. Three patients of the TERPT group required an additional abdominal approach. The rate of early complications was higher in the TERPT group. Long-term bowel function was assessed in 31 patients for the TERPT group and 24 patients for the LA-TERPT group. Outcomes showed that the bowel functional outcome was good (BFS ≥ 17) in 55% (n = 17) of TERPT group and 54% of LA-TERPT group (p = 0.97), moderate (BFS 12 to 16) in 16% (n = 5) and 33% (n = 8), respectively (p = 0.24), and poor in 29% (n = 9) and 13% (n = 3), respectively (p = 0.23).

CONCLUSIONS

Both TERPT and LA-TERPT techniques should be considered safe and feasible for the treatment of HD patients. TERPT patients present faster time to return to normal bowel function while LA-TERPT patients have slightly lower incidence of postoperative complications. Long-term functional outcomes are similar between the two groups.

Single-stage laparoscopic transanal pull-through modified Swenson procedure without leaving a muscular cuff for short- and long-type Hirschsprung disease: a comparative study

PURPOSE

The Soave procedure (SO) is performed most commonly for Hirschsprung disease. SO reduces the risk of injury to the pelvic structures; however, a residual aganglionic muscle cuff could interfere with bowel movement and lead to obstructive enterocolitis. The Swenson procedure is considered ideal in terms of peristalsis. Currently, laparoscopic surgery provides better visualization and facilitates precise dissection, possibly leading to feasible performance of the laparoscopic modified Swenson procedure (SW). We present our operative technique and the efficacy of the SW compared with that of SO.

METHODS

We retrospectively reviewed the records of 16 and 27 patients who underwent SW and SO, respectively, between 2012 and 2017.

RESULTS

Operative time, blood loss, length of stay, and frequency of bowel movements showed no significant difference between the two groups. In the SW group, temporary dysuria occurred in one patient, postoperative enterocolitis in two, wound infection in one, and severe perianal excoriation in four, whereas in the SO group, obstructive symptoms occurred in three patients, small-bowel obstruction in one, and severe perianal excoriation in three. The complications and outcomes were comparable between both groups.

CONCLUSION

Laparoscopic SW was safe and feasible for the short-term follow-up outcomes.

Meta-analysis of hybrid natural-orifice transluminal endoscopic surgery versus laparoscopic surgery

Background

Hybrid natural-orifice transluminal endoscopic surgery (NOTES), combining access through a natural orifice with small-sized abdominal trocars, aims to reduce pain and enhance recovery. The objective of this systematic review and meta-analysis was to compare pain and morbidity in hybrid NOTES and standard laparoscopy.

Methods

A systematic literature search was performed to identify RCTs and non- RCTs comparing hybrid NOTES and standard laparoscopy. The main outcome was pain on postoperative day (POD) 1. Secondary outcomes were pain during the further postsurgical course, rescue analgesia, complications, and satisfaction with the cosmetic result. The results of meta-analysis in a random-effects model were presented as odds ratio (ORs) or standard mean differences (MDs) with 95 per cent confidence intervals.

Results

Six RCTs and 21 non-randomized trials including 2186 patients were identified. In hybrid NOTES the score on the numerical pain scale was lower on POD 1 (−0·75, 95 per cent c.i. −1·09 to −0·42; P = 0·001) and on POD 2–4 (−0·58, −0·91 to −0·26; P &lt; 0·001) than that for standard laparoscopy. The need for rescue analgesia was reduced in hybrid NOTES (OR 0·36, 0·24 to 0·54; P &lt; 0·001). The reduction in complications found for hybrid NOTES compared with standard laparoscopy (OR 0·52, 0·38 to 0·71; P &lt; 0·001) was not significant when only RCTs were considered (OR 0·83, 0·43 to 1·60; P = 0·570). The score for cosmetic satisfaction was higher after NOTES (MD 1·14, 0·57 to 1·71; P &lt; 0·001).

Conclusion

Hybrid NOTES reduces postoperative pain and is associated with greater cosmetic satisfaction in selected patients.
