Impact of “Lateralizing” the Sigmoid Colostomy on Port Ergonomics in Laparoscopic Anorectoplasty for High Anorectal Malformations

Introduction The high-type anorectal malformations (ARM) are conventionally managed by an initial left iliac fossa sigmoid colostomy, followed by laparoscopic anorectoplasty (LARP). Such a stoma occupies left half of the infraumbilical region and hinders the LARP ergonomics, leading to the surgeon's discomfort. We studied the outcome and impact of “lateralizing” (shifting laterally in the abdominal wall) the colostomy on port ergonomics. Materials and Methods This prospective study was conducted in the pediatric surgery unit of a medical college in central India between March 2014 and June 2017 in two parts. In the first part of the study, neonates with high ARM were block randomized in two groups: conventional colostomy (CC) in left iliac fossa and lateral colostomy (LC, laterally placed abdominal colostomy). Outcomes of colostomy were compared among these two groups. In the second part of the study, 40 consecutive infants from both types of colostomy groups underwent ergonomic comparison and assessment of the surgeon's discomfort during LARP (CC-LARP and LC-LARP). Standard statistical tests were used for comparison. Results In the first part of the study, 203 ARM cases were included in this study; 100 underwent CC and 103 underwent LC. Colostomy prolapse, excoriation, reversed stoma, and short distal limb were significantly higher in the CC group. In the second part of the study, the LC-LARP group showed many significant advantages over the CC-LARP group, including less peri-stomal adhesions, better vision, shorter operative time, and better ergonomics (better manipulation, elevation, and azimuth angles). The LC-LARP also significantly reduced the surgeon's discomfort. Conclusion Lateralization of high-sigmoid colostomy should be preferred over left iliac fossa sigmoid colostomy for ARM, as it improves the port ergonomics and reduces the surgeon's discomfort for second stage LARP.

A Rare Case of Isolated Sigmoid Colon Perforation in Patient with Blunt Trauma Abdomen

A 47 years old male presented to emergency department with history of pain abdomen after road traffic accident 6 hours back. He had deceleration injury while driving a minivan when he hit a truck parked on road side. On presentation, his Airway and breathing was intact with GCS 15/15.Pulse was 110/min and blood pressure was 100/70 mmHg. His abdomen was generalized tender, mostly in the hypogastrium. Digital rectal examination was normal. Ultrasound abdomen showed free fluid in the peritoneal cavity and chest and abdominal X-rays were unremarkable. On opening the abdomen there was 7×7 cm isolated perforation in sigmoid colon 5 cm proximal to recto sigmoid junction. Repair of perforation was done and proximal double barrel sigmoid colostomy was made. Patient was discharged on 3rd post-operative day. Later after 4 months reversal of sigmoid colostomy was done and patient was discharged.

Comparison of frequency of complications in loop versus divided colostomy in patients with high variety anorectal malformation

Background: The objective of this study was to compare frequency of stoma related complications of loop versus divided sigmoid colostomy for the management of high variety anorectal malformations. Methodology: This RCT was conducted in the department of Pediatrics Surgery Department of the Children’s Hospital and the Institute of Child Health Lahore, for the period of one year from 1st May 2016 to 1st June 2017. One hundred and twenty patients (Sixty patients in each group) of anorectal malformation meeting inclusion criteria were taken in this study. Patients were divided into two groups randomly using lottery method; loop sigmoid colostomy in Group-A and divided sigmoid colostomy in Group-B. After surgeries patients were followed weekly up till 8 weeks. Stoma related complications (as per operational definition) were noted. Results: The mean age in group –A and group-B were 3.34 ± 1.12 days and 3.36 ± 0.97 days, respectively. In group – A there were 52(86.67%) male and 8(13.33%) females, and in group-B there were 45(75%) male and 15(25%) female patients. In group-A 22(36.66%) patients had complications [3(5.00%) patients had retraction, 8(13.33%) had prolapse, 4(6.67%) had stoma obstruction, parastomal hernia were seen in 4(6.67%), stoma necrosis were seen in 3 (5.00%)] and in group-B, 16(26.66%) patients had different complications [1(1.67%) patients had retraction, 3(5.00%) had prolapse, 5(8.33%) had stoma obstruction, parastomal hernia were seen in 2(3.3%), stoma necrosis were seen 5(8.33%)]. The complications in group-A were higher when compared to group-B, but (p-value = 0.650) were not significant statistically except for stoma prolapse. Conclusion: Though complication rate in both techniques is not statistically different but frequency of stoma prolapse is more in loop colostomy group. Therefore, divide colostomy should be opted as preferred technique.

Image of the Month: High Pressure Distal Colostogram in a Patient with an Anorectal Malformation

An adequately performed high pressure distal colostogram is crucial to plan surgery in male patients born with anorectal malformations. We present two male patients that underwent a divided sigmoid colostomy with distal mucus fistula in the neonatal period and at 6 months of age underwent a high pressure distal colostogram. In the discussion, we will give some tricks beyond the known rules: how to correctly interpret a high pressure distal colostogram, how to identify the level of a recto-urinary fistula, and how to accurately plan the surgical approach.

Divided and Separated Sigmoid Colostomy in Anorectal Malformation : Six Years Experience at Dhaka Shishu Hospital

Background : There are various surgical options for management of anorectal malformations (ARM). Colostomy is a common part of the management of high anorectal malformation in the pediatric population.Objective : The aim of this study was to find out the most common complications after formation of divided sigmoid colostomy.Methods : This prospective observational study was done in the Division of Pediatric Surgery, Bangladesh Institute of Child Health and Dhaka Shishu (Children) Hospital, Dhaka from January 2012 to December 2017. Divided and separated sigmoid colostomy was doneon 116 patients admitted with ARM during this period. Follow up on 2nd, 4th and 8th week after operation was done and in each follow up patients were assessed clinicallyfor wound infection, skin excoriation, prolapse of colostomy, retraction of colostomy and parastomal hernia. If colostomy complications were found then managed as per standard method.Results : The mean age of patients was 2.43±1.29 days and majority of the patients 66 (56.9%) were male.About half of the patients 50(43.1%) had fistula and 21(18.1%) patients had associated anomaly. Among 116 patients 51 (43.97%) developed complications after colostomy. The most common complication was skin excoriation found in 35 (30.2%) patients followed by wound infection in 8(6.9%). Prolapse and retraction of colostomy was found only in 6 (5.17%)and 2 (1.7%) cases respectively. No patient developed parastomal hernia and there was no mortality.Conclusion : Divided and separated sigmoid colostomy provided satisfactory outcome in the management of high anorectal malformation. Skin excoriation was the most common complication and few developed wound infection and prolapse of colostomy.Northern International Medical College Journal Vol.9(2) Jan 2018: 311-314
