RESUMO

The aim of this study is to report the experience of implementing a pediatric robotic surgery program at a free-standing pediatric teaching hospital. A database was created to prospectively collect perioperative data for all robotic surgeries performed by the pediatric surgery department. The database was queried for all operations completed from October 2015 to December 2021. Descriptive statistics were used to characterize the dataset, using median and interquartile ranges for continuous variables. From October 2015 to December 2021, a total of 249 robotic surgeries were performed in the department of pediatric surgery. Of the 249 cases, 170 (68.3%) were female and 79 (31.7%) were male. Across all patients, there was a median weight (IQR) of 62.65 kg (48.2-76.68 kg) and a median (IQR) age of 16 years (13-18 years). The median (IQR) operative time was 104 min (79.0-138 min). The median console time was 54.0 min (33.0-76.0 min) and the median docking time was 7 min (5-11 min). The majority of procedures were performed on the biliary tree (52.6%). In the 249 procedures, there were no technical failures of the robot and only two operations (0.8%) were converted to open procedures and one (0.4%) to laparoscopic. This study highlights the ability to successfully integrate a pediatric robotic surgery program into a free-standing children's hospital with a low conversion rate. Additionally, the program extended across multiple surgical procedures and offered real-time exposure to advanced surgical techniques for current and aspiring pediatric surgery trainees.

RESUMO

Introduction: In children, gallbladder disease has become more common due to the rise in childhood obesity and subsequent shift in etiology. While the gold standard of surgical management remains a laparoscopic technique, there has been increasing interest in robotic-assisted techniques. The aim of this study is to report a 6-year update on the experience of treating gallbladder disease with robotic-assisted surgery at a single institution. Materials and Methods: A database was created to prospectively collect patient demographic and operative variables at the time of operation from October 2015 to May 2021. Descriptive analysis of select available variables was performed using median and interquartile ranges (IQRs) for all continuous variables. Results: In total, 102 single-incision robotic cholecystectomies and one single-port subtotal cholecystectomy were performed. From available data, 82 (79.6%) patients were female, median weight was 66.25 kg (IQR: 58.09-74.24 kg), and median age was 15 years (IQR: 15-18 years). Median procedure time was 84 minutes (IQR: 70.25-103.5 minutes) and median console time was 41 minutes (IQR: 30-59.5 minutes). The most frequent preoperative diagnosis was symptomatic cholelithiasis (79.6%). One (0.97%) operation was converted from a single-incision robotic approach to open. Conclusion: Single-incision robotic cholecystectomy is a safe and reliable technique for the treatment of gallbladder disease in the adolescent population.

RESUMO

PURPOSE: We compare our experience of percutaneous endoscopic gastrostomy, introducer technique (PEG) and laparoscopic technique (LapGT) at a tertiary care pediatric hospital. METHODS: Isolated PEGs and LapGTs placements were reviewed at our institution from August 2016 through January 2018. Demographics, procedure time, operative charges, and 30-day complications were reviewed. Means of quantitative values were compared using the student's t test. Categorical values were compared using the X2 test. RESULTS: Ninety-three isolated gastrostomy tubes were placed in children aged 2 weeks to 19 years. There were 56 PEGs (60%) and 37 LapGTs (40%), based on surgeon preference. There was no significant difference in demographics between the two groups. Mean operative time for PEG was 59% shorter (14 vs. 33 min, p < 0.001). Operating room charges averaged $4500 less in the PEG group ($11,400 vs. $15,900, p < 0.001). Neither group had complications that required a return to the operating room within 30 days postoperatively. There was no difference in the rate of fundoplication after gastrostomy tube placement. In two cases PEGs were converted to LapGTs after safety criteria for PEG were not met. CONCLUSION: The PEG introducer technique, when used with clearly defined safety criteria, decreased operative time and cost without compromising safety. LEVEL OF EVIDENCE: III.

RESUMO

Purpose: There is no one standard procedure encompassing the needs and differences of the entire pediatric population for inguinal hernia repair (IHR). Several techniques can be used, including open repair, laparoscopic, and robotic-assisted laparoscopic repair. This is a report of a single pediatric hospital's experience performing robotic-assisted IHRs in an adolescent population. Methods: Robotic IHRs performed by the pediatric surgery department were prospectively captured and reviewed. The operation performed was a modified robotic transabdominal preperitoneal approach with ProGrip mesh. Results: Between January 2016 and August 2020, 11 robotic-assisted IHRs occurred. All patients were male, median weight interquartile range (IQR) was 76.6 kg (67.425-90.4 kg) and median age (IQR) was 17 years (17-18.5). All together median (IQR) total operative time was 111 (97.5-126) minutes, median (IQR) total console time was 60 (55.5-75.5) minutes. There were no complications or conversions, with all patients discharged on the day of the operation. Conclusion: This study demonstrates a safe and reliable approach to repairing inguinal hernias using robotics through a small initial case series. Robotic-assisted IHR should be considered a viable technique to optimize the surgical care of adolescents.

RESUMO

In this review, the care of children with a previously repaired anorectal malformation is explored. We know that the surgical care of children with anorectal malformations is complex; however, despite an increased understanding of the congenital anomaly and significant technical advances in the operative repair, many of these children continue to have poor functional outcomes. In this article we focus on the common surgical complications, discuss typical presentations, consider appropriate investigations, and review the risks and benefits of revisional surgery in those patients that are 'not doing well' following their primary reconstruction.

RESUMO

BACKGROUND: Persistent or recurrent idiopathic rectal prolapse in children requires surgical intervention. Several techniques have been used to repair this problem. However, recurrence and complications continue to be a challenge in the management of this condition. Here we report our experience in using the modified Delorme's procedure to treat such patients. METHODS: We conducted a retrospective observational study of patients with idiopathic rectal prolapse who underwent the modified Delorme's procedure during 2013-2017. We analyzed the clinical characteristics of the patients and the recurrence and complication rates during a follow-up of 15-68 months. RESULTS: We included 14 patients. The age at operation ranged from 2 to 17 years, and the length of the prolapse was 3-15 cm. There were no intraoperative or postoperative complications. All patients achieved postoperative fecal control, and there were no recurrences. CONCLUSION: The modified Delorme's procedure was effective for the treatment of idiopathic rectal prolapse. There were no recurrences or complications. Because it is a perineal technique, the procedure avoids the risk of nerve injury that exists for transabdominal methods.

RESUMO

INTRODUCTION: Transanastomatic feeding tube (TAT) use in the repair of tracheoesophageal fistulas (TEF) with or without esophageal atresia (EA) and EA with or without TEF allows for earlier enteral feedings, however, may predispose to esophageal stricture. METHODS: We review our institutional experience with esophageal atresia repair over a 15-year period from 2000 to 2015 and report on our observed complication rate with emphasis on the surgical approach and use of TATs. RESULTS: We identified 110 TEF repairs. Ninety-six were Type C, 7 were Type A, 4 were Type D, and 3 were Type E (H-Type). TATs were used in 74% of patients. The stricture rate with the TAT approached 56% versus 17% without a TAT (p<0.0005). There was no difference in leak rate (p=0.27). Ninety-four TEF repairs were performed via open thoracotomy, and 16 were initially approached thoracoscopically. Six out of 16 that were started thoracoscopically were completed with the minimally invasive approach. Whether the case was started thoracoscopically, completed thoracoscopically, or performed open made no difference in the rate of stricture or anastomotic leak, but we did observe an increase in musculoskeletal complications in the open thoracotomy group (28% vs. 0). CONCLUSION: Our data suggests that the use of TATs does not protect against anastomotic leak, but may increase stricture rate. Further, the thoracoscopic group showed no difference in the leak or stricture rate and demonstrated less musculoskeletal complications. Confirmation of these findings will require a prospective study. LEVEL OF EVIDENCE: III.

RESUMO

BACKGROUND/PURPOSE: Fecal incontinence after a pull-through is associated with different factors, although damage to the anal canal seems to be the most important. The objective of this article is to identify the variables related to the presence of fecal control and colitis in a homogeneous group of children after pull-through. METHODS: A retrospective cross-sectional study was performed in patients with HD for evaluation of post-operative problems from May 2014 to November 2016. The patients (39) had a transanal approach and were divided into two groups: Group 1 patients with fecal continence and Group 2 patients with fecal incontinence. RESULTS: Group 1 patients (13) had the anastomosis in the rectum, no damage to the anal canal, and a positive history of colitis. Group 2 (26) had the anastomosis at the skin, anoderm, pectinate line, or a combination of these and a negative history of colitis. CONCLUSIONS: We demonstrated that patients with a technical error in the anastomosis have fecal incontinence, but not colitis. Preservation of the anal canal is associated with fecal control and colitis because it is a high-pressure zone. Education for proper identification of the anal canal during a pull-through is an absolute necessity. TYPE OF STUDY: Retrospective Comparative Study. LEVEL OF EVIDENCE: Level III.

RESUMO

BACKGROUND: The association of rectovestibular fistula (RVF) and vaginal agenesis (VA) presents a diagnostic and management challenge. The vaginal replacement is usually performed with rectum or sigmoid, which are the natural fecal reservoirs; thus, the fecal control could be affected. We present our experience utilizing ileum to preserve the rectum and sigmoid. METHODS: We performed a retrospective study of eight patients with RVF and VA treated from May 2011 to June 2015 at two colorectal centers, at Pittsburgh and Mexico. We recorded the age at diagnosis of VA, treatment, presence of other associated malformations and outcome. RESULTS: Eight of forty-nine girls with RVF had an associated VA (16.3%). Three patients had a timely diagnosis and five a delayed diagnosis. Six patients were submitted to a vaginal replacement with ileum and achieved fecal control. Two are waiting for surgery. CONCLUSIONS: A high index of suspicion of vaginal agenesis helps in a timely diagnosis in girls with RVF. The use of ileum allows for preservation of the fecal reservoirs, thus optimizing the chance for fecal control in patients with anorectal malformations.

RESUMO

PURPOSE: To present our experience in patients with chronic idiopathic constipation complicated by megarectosigmoid and fecal incontinence who underwent a primary sigmoidectomy and appendicostomy. METHODS: We reviewed eight patients referred to the Colorectal Center from 2014 to 2016 with chronic idiopathic constipation and undergoing a sigmoidectomy and appendicostomy. We analyzed the previous medical treatment, indications for the surgical procedure, and outcomes. RESULTS: Age at operation was 5-19 years. Time with constipation was 4-15 years. All patients received multiple laxatives, mainly polyethylene glycol, and all had severe social problems. Four patients have autism. The indication for surgery was an unsuccessful laxative trial, refusal to continue with rectal enemas or both, and social fear of continued fecal incontinence. Post-operatively, all patients were having daily bowel movements without fecal accidents. CONCLUSION: Selected patients with chronic idiopathic constipation complicated by megarectosigmoid and fecal incontinence can obtain great benefit from primary sigmoidectomy and appendicostomy.

RESUMO

INTRODUCTION: The purpose of this study was to assess the utility and strength of a novel endoscopic fixation device, Brace-Bar, in the large intestine and compare the strength with other currently available techniques. The primary outcome was the strength of fixation using 3 endoscopic methods: BraceBar, suture, and commercially available tackers. The hypothesis is that the use of the BraceBar will result in fixation strength similar to the strength of the other methods. MATERIALS AND METHODS: An ex vivo porcine model was used to test 3 fixation methods: Group 1, BraceBar (Prototype); Group 2, ProTack (AutoSuture); and Group 3, TI-CRON suture (Syneture). Large-bowel segments were fixed to abdominal wall tissue at 20 cm from the distal end of the rectum. Primary endpoint was pull away strength. A total of 45 trials of each method were performed. Comparison between the groups was done using JMP 7.0. RESULTS: There was no significant difference in strength between the BraceBar group and the suture group ( P = .1236). The BraceBar method demonstrated significantly higher strength compared with the tacker group (P = .003). CONCLUSION: Use of the BraceBar for fixation of the large bowel is at least comparable with suture fixation, making clinical use of BraceBar a reasonable consideration. Use of this device may make endoscopic repair of certain intestinal conditions feasible.

RESUMO

OBJECTIVE: to evaluate the capacity of Imipenem as a prophylactic treatment for decreasing the number of infected necrosis and surgeries, as well as for diminishing septic complications and the mortality rate among patients with severe acute necrotizing pancreatitis. MATERIAL AND METHODS: from May 2005 to December 2007 a prospective randomized study was conducted in order to evaluate the efficacy of a prophylactic antibiotic therapy in patients with pancreatic necrosis. During this time period 58 patients entered the study protocol. Patients were divided in two groups; the first one underwent antibiotic therapy with Imipenem while the second group received no prophylactic treatment at all. All patients received early enteral nutrition. RESULTS: both studied groups had comparable age, gender ratio, and C.R.P and necrosis percentages. When comparing general morbidity in both groups no difference was found between the group receiving a prophylactic antibiotic and the group that did not receive it (58% vs. 56%). Moreover, when the septic complications were evaluated, it was confirmed that these were more frequent among the group of patients receiving Imipenem (29%), in comparison to the group that did not received antibiotics (15%). 12.5% of the patients that received Imipenem developed pancreatic necrosis infection, while said infection only appeared in 6% of the patients in the group that did not receive antibiotic prophylaxis; nevertheless, none of the comparisons reached statistical significance. The number of patients who required surgery was similar in both groups. When comparing the hospital stay, it was observed that this was longer among the patients receiving prophylactic therapy. No patient died during the study. CONCLUSION: The present study finds no benefits in the use of antibiotic therapy with Imipenem regarding the risk of developing pancreatic necrosis infection and septic complications, and neither when trying to reduce the number of surgeries among patients with severe acute pancreatitis with necrosis.
