Transumbilical laparoscopy-assisted Malone procedure for fecal incontinence in children

BACKGROUND

Transumbilical laparoscopy-assisted Malone procedure (TULAM) is a single-incision laparoscopic procedure in which the appendicostomy is made at umbilicus. The aim of this study is to evaluate the outcomes of TULAM.

METHODS

With IRB approval, the medical records of the patients who underwent TULAM were retrospectively reviewed between July 2013 and December 2018. The data collected included ages, gender, underlying diseases, operative techniques, complications, stoma continence, parental satisfaction and follow-up duration.

RESULTS

Fifteen patients underwent TULAM at the median age of 5.0 years (2.9-10.7 years). There were 4 girls and 11 boys. Thirteen patients had anorectal malformations or cloaca; the other two patients had spina bifida. All patients presented with fecal incontinence; 9 of them had concomitant constipation. TULAM was successfully accomplished in 14 patients; one patient required conversion to the three-port procedure. The median follow-up period was 1.7 years (0.5-3.2 years). One patient required tube replacement under endoscopy guidance in the operation room. One patient required surgical revision because the appendix was disrupted after an episode of enterocolitis. All patients were socially continent with antegrade enemas. 12 patients were stoma continent, and 3 patients had minor leaking less than once a month. The stoma cosmesis was satisfactory. All parents expressed satisfaction with TULAM.

CONCLUSION

TULAM is effective in the management of fecal incontinence and constipation, and provides a continent stoma with excellent cosmesis.

Sacral Curvature in Addition to Sacral Ratio to Assess Sacral Development and the Association With the Type of Anorectal Malformations

Introduction: Sacral ratio (SR) is currently the only measurement to quantitatively evaluate sacral development in patients with anorectal malformations (ARM). This study proposes sacral curvature (SC) as a new indicator to qualitatively assess the sacrum and hypothesizes that sacral development, both quantitatively and qualitatively, can be an indicator to predict the type of ARM. The study aims to investigate the difference of SR and SC between ARM types and the association with the type of ARM. Methods and Materials: This study was retrospectively conducted between August 2008 and April 2019. Male patients with ARMs were enrolled and divided into three groups based on the types of ARM: (1) rectoperineal fistulae, (2) rectourethral-bulbar fistulae, and (3) rectourethral-prostatic or rectobladder-neck fistulae. SC was measured in the sagittal views of an MRI or a lateral radiograph of the sacrum. Results: Included in the study were 316 male patients with ARMs. SRs were 0.73 ± 0.12, 0.65 ± 0.12, and 0.57 ± 0.12 in perineal, bulbar, and prostatic/bladderneck fistula, respectively (p < 0.01). The SCs in perineal fistulae and bulbar fistulae were significantly higher than that in prostatic/bladderneck fistulae (0.25 ± 0.04, 0.22 ± 0.14, and 0.14 ± 0.18, p < 0.01). When SR ≥ 0.779, there was an 89.9% of possibility that the child has a perineal fistula. When SR ≤ 0.490 and SC ≤ 0, the possibilities of the child having prostatic/bladderneck fistulae were 91.6 and 89.5%, respectively. SC < 0 was also noted in 27 (27.8%), 19 (10.5%), and no (0%) patients of prostatic/bladderneck, bulbar, and perineal fistulae (p < 0.01), respectively. Sacral defect was noted in 63% of patients with SC ≤ 0, compared to none with SC > 0 (p < 0.01). Conclusions: The higher the rectal level is in an ARM, the lower are the objective measurements of the sacrum. SC ≤ 0 is associated with sacral defects and implies a high likelihood of prostatic/bladderneck fistulae.

Single-site laparoscopic burnia for inguinal hernias in girls: comparison with open repair

BACKGROUND

Burnia is a suturless repair for inguinal hernias in girls. It is performed under laparoscopy by grabbing the sac, inverting it into the peritoneal cavity, and cauterizing. The aim of this study is to report our experience with single-site laparoscopic burnia (BURNIA) and compare them with open repair (OPEN).

METHODS

With IRB approval, pediatric female patients younger than 18 years of age who underwent inguinal hernia repair between January 2015 and December 2017 were enrolled. Medical records were retrospectively reviewed. The patients were divided into two groups, BURNIA and OPEN.

RESULTS

198 patients were included. In BURNIA, 49 patients underwent bilateral repairs, and 50 patients underwent 51 unilateral repairs (one patient had metachronous contralateral hernia). In OPEN, 27 patients underwent bilateral repairs, and 72 patients underwent 77 unilateral repairs (five patients had metachronous contralateral hernias). The mean age of BURNIA was similar to OPEN for bilateral repairs (49.1 ± 36.6 vs. 43.7 ± 26.4 months, p = 0.46), but significantly older for unilateral repairs (54.6 ± 29.8 vs. 29.0 ± 31.4, p < 0.01). The mean operation time of BUNIA was similar to OPEN for bilateral repairs (24.2 ± 7.6 vs. 22.4 ± 8.6 min, p = 0.35), but significantly longer for unilateral repairs (19.2 ± 7.0 vs, 13.6 ± 8.8 min, p < 0.01). The mean follow-up duration of BURNIA was significantly shorter than OPEN for bilateral and unilateral repairs, respectively (32.5 ± 8.8 vs. 45.4 ± 4.8 months, p < 0.01) (30.2 ± 8.8 vs. 39.1 ± 9.6 months, p < 0.01). No conversion was required in BURNIA. There were no complications and no recurrence in all patients.

CONCLUSIONS

Single-site laparoscopic burnia is technically feasible, and as safe and effective as open inguinal hernia repair.

Should single-incision laparoscopic appendectomy be the new standard for pediatric appendicitis?

BACKGROUND

To compare single-incision laparoscopic appendectomy (SILA) with conventional (CLA) and transumbilical laparoscopic appendectomy (TULA).

METHODS

This is a retrospective cohort study. Patients were divided into three groups, SILA, CLA, and TULA. SILA was defined as performing appendectomy extracorporeally or intracorporeally by using a glove-port incorporated with 3 trocars. TULA was defined as exteriorizing appendix and performing extracorporeal appendectomy by using an operative telescope. Statistical analysis was conducted in patients with simple (SA) and complicated appendicitis (CA), respectively.

RESULTS

A total of 315 patients were enrolled, including 161 in SILA, 105 in CLA, and 49 in TULA. Demographic data were similar. In patients with simple appendicitis, operation time of SILA was shorter than CLA but longer than TULA (62.8 ± 22.5 vs. 82.2 ± 24.3 and 51.6 ± 22.3 min, p < 0.01). SILA had shorter hospital stay than CLA, and similar to TULA (56.1 ± 20.4 vs. 71.5 ± 37.8 and 56.9 ± 19.0 h, p < 0.01). In patients with complicated appendicitis, SILA had shorter operation time than CLA, but a similar time to TULA (80.9 ± 22.4 vs. 105.7 ± 28.8 and 82.5 ± 31.2 min, p < 0.01). Conversion to open surgery was not required in all groups. The rates of complications, such as wound infection, intraabdominal abscess and adhesion ileus, were similar. SILA required fewer additional ports than TULA in both simple and complicated appendicitis (1.1% vs. 13.5%, and 9.6% vs. 41.7%, p < 0.01).

CONCLUSION

SILA has the advantages of shorter operation time and hospital stay over CLA as well as a lower rate of additional ports than TULA.

How much do we know about constipation after surgery for anorectal malformation?

BACKGROUND

To evaluate the occurrence of constipation after anorectal malformations (ARM) repair and the results of laxative treatment.

METHODS

Between August 2012 and July 2017, the clinical data of patients with ARMs was prospectively collected. The patients were divided into two groups, good types and poor types. Good types included rectoperineal, rectovestibular, rectourethral bulbar, and no fistula. Risk factors were defined as spinal cord anomalies, sacral ratio <0.4, or cognitive impairment. Success was defined as that laxative could be tapered.

RESULTS

Eighty-four patients were enrolled with mean age of 6.3 ± 7.8 (0.6-59.9) years. The mean age of onset of constipation was 12.8 ± 8.3 months and the mean interval was 5.9 ± 5.1 months after reconstructions. The interval was not significantly different between patients with good types and poor types. In 23 patients with severe constipation being treated for >6 months, 14 of 18 (77.8%) patients with good types were classified as success, whereas only 1 of 5 (20%) patients with poor types was (p = 0.02). In patients with good types, 9 of 9 (100%) patients with no risk factors were successful; however, only 5 out of 9 (55.6%) patients with risk factors were successful (p = 0.02).

CONCLUSION

Constipation occurs shortly after operations. Patients with good types and no risk factors are susceptible to weaning laxatives.

Single-incision laparoscopic surgery for idiopathic intussusception in children: Comparison with conventional laparoscopy

BACKGROUND

The aim of this study is to evaluate the feasibility of single-incision laparoscopic surgery (SILS) for idiopathic intussusception in children and compare the outcomes with conventional laparoscopy (CLS).

METHODS

Between January 2011 and December 2012, patients who underwent CLS for idiopathic intussusception were assigned into the group of CLS. Between January 2013 and March 2017, patients who underwent SILS were assigned to the group of SILS. For patients who failed to reduce by SILS, bimanual transabdominal approach was conducted.

RESULTS

A total of 23 patients were enrolled, including 7 and 16 patients in SILS and CLS, respectively. The mean age was similar in both group (22.4 ± 18.7 vs. 24.6 ± 18.6 months, p = 0.80). There is no difference in gender distribution. The main indication was radiological reduction failure in both groups (85.7% vs. 75%, p = 0.58). Ileocolic intussusception was found in 6 (85.7%) and 15 (93.8%) patients of SILS and CLS, respectively (p = 0.25). The level of intussusception was at ascending colon in 3 (42.9%) and 12 (75.0%) patients, respectively (p = 0.11). The operation time was similar in both groups (64.9 ± 53.7 and 70.9 ± 26.1 min, p = 0.79). There were 2 (28.6%) and 1 (6.2%) conversions, respectively (p = 0.15). For the two patients in SILS, the intussusception was successfully reduced by bimanual transabdominal approach. There was no significant difference in time to feeding (1.9 ± 1.1 vs. 1.4 ± 0.7 days, p = 0.21). The mean length of postoperative hospital stay was 3.9 ± 1.6 and 3.1 ± 1.1 days, respectively (p = 0.17).

CONCLUSIONS

SILS for pediatric intussusception is technically feasible and has comparable results to CLS. Transabdominal bimanual reduction is applicable in cases of failed laparoscopic reduction.

Transumbilical minilaparotomy in low-birthweight newborns for complicated conditions

BACKGROUND

The purpose of this study is to examine the outcome of transumbilical minilaparotomy for infants and compare the results between normal birthweight (NBW) and low birthweight (LBW).

METHODS

Between July 2010 and March 2017, infants who underwent abdominal surgery through transumbilical minilaparotomy were enrolled. Medical records were retrospectively reviewed. Patients were divided into two groups, NBW and LBW. Complexity was defined as complicated conditions other than intestinal atresia and malrotation.

RESULTS

Totally, 16 patients were included. The diagnosis included intestinal atresia (n = 3), meconium peritonitis (n = 4), bowel infarction/necrosis (n = 4), spontaneous intestinal perforation (n = 2), segmental volvulus and necrosis (n = 1), necrotizing enterocolitis (n = 1), and malrotation (n = 1). The median gestational age and body weight were 32 (24-40) weeks and 1731 (560-4200) grams respectively. The median age at operation was 3 (1-41) days. The surgical procedure included primary repair of the intestine (n = 14), ileostomy (n = 1) and Ladd's procedure (n = 1). Postoperative complications included anastomotic leakage (n = 2), adhesion ileus (n = 1), and missed rectal atresia (n = 1). There was one mortality due to extremely low birthweight and poor lung maturation. Re-operation was required in 3 patients for anastomotic leakage (n = 2) and missed rectal atresia (n = 1). Mean birthweight was 2932 ± 97 and 1263 ± 667 g in NBW (n = 5) and LBW (n = 11), respectively (p < 0.01). Complexity rate was 40% and 90.9%, respectively (p = 0.034). The mean operation time was 139.4 ± 65.8 and 124.3 ± 46.1 min, respectively (p = 0.60). The complicated rate and reoperation rate were similar.

CONCLUSIONS

Transumbilical minilaparotomy is technically feasible and an alternative option of minimally invasive surgery for LBW infants and complex conditions.

Children With Inguinal Hernia Repairs: Age and Gender Characteristics

Objective. This study reports the age and gender characteristics of children with inguinal hernia repairs (International Classification of Diseases, Ninth Revision, Clinical Modification [ICD-9-CM] Operation Codes 530-533). Methods. We used a retrospective cohort study design based on 2 data sources from 2007 to 2011 (the Bureau of National Health Insurance, Department of Health, Taiwan, and a local teaching children's hospital database) and descriptive statistics to analyze the group's age and gender differences as independent variables. Results. The gender ratio was 7 males to 1 female in the general population, whereas the gender ratio in children was 3.5 males to 1 female. Gender difference was found statistically significant in the age subgroup difference: boys (49.1%) were more than girls (39.3%) in ages 1 to 4, while girls (37.8%) were more than boys (23.7%) in ages 5 to 9. Based on the local hospital's data, of those 611 (15%) children born and who received herniorrhaphy, 204 (33.4%) were born as preterm infants and 407 (66.6%) as term infants. The gender ratio among 204 children born prematurely and received herniorrhaphy was 3 males to 1 female. Of those 353 infants under 6 months who received herniorrhaphy, 155 (76%) were preterm infants while 198 (48.6%) were term infants. Conclusion. Early screening of inguinal hernia for children is important and should focus on those born prematurely, particularly those aged <6 months and boys.

Extracorporeal and intracorporeal approaches of single-incision laparoscopic appendectomy in children: is one superior to another?

BACKGROUND

Single-incision laparoscopic surgery has been widely popularized for pediatric appendicitis. Various techniques have been proposed with two main approaches: extracorporeal and intracorporeal. The purpose of this study is to compare the result of different approaches in single-incision laparoscopic appendectomy (SILA) in children.

MATERIAL AND METHODS

With IRB approval, patients less than 18years of age who underwent SILA were enrolled from July 2012 to December 2015. The patients were divided into three groups based on surgical approach: extracorporeal (Extra), mixed (Mix), and intracorporeal (Intra) approaches. Parameters were retrospectively reviewed, including age, gender, white blood cell (WBC), operation time, operative findings, time to diet, length of hospital stay (LOS), and complications. Statistical analysis was performed separately for simple and complicated appendicitis.

RESULTS

There were 32, 32, and 24 patients with simple appendicitis in Extra, Mix, and Intra respectively. There were 27, 15, and 31 patients with complicated appendicitis in the three groups, respectively. No significant difference was noted in the mean age, gender distribution, or WBCs between the different groups. A higher percentage of patients with complicated appendicitis received intracorporeal approach than those with simple appendicitis (42.5% vs. 27.3%, p=0.044). In simple appendicitis, the LOS was significantly longer in Extra as compared to Mix (p=0.043). Otherwise, the mean LOS, time to diet, and complications were not significantly different. The mean operation time was similar between groups of simple appendicitis (56.5±19.5, 63.6±23.5, and 70.1±23.1 min, p=0.08), whereas it was significantly shorter in Extra of complicated appendicitis (67.6±16.4, 86.6±19.0, and 89.9±23.4 min, p<0.001). Multivariate analysis showed that intracorporeal approach is an independent factor for prolonged operation time in both simple and complicated appendicitis.

CONCLUSIONS

Different approaches of SILA in children have similar outcomes for both simple and complicated appendicitis. Extracorporeal is the most time efficient; however, intracorporeal can be helpful to deal with complex situations.

Juvenile polyposis syndrome: An unusual case report of anemia and gastrointestinal bleeding in young infant

BACKGROUND

Juvenile polyposis syndrome, a rare disorder in children, is characterized with multiple hamartomatous polyps in alimentary tract. A variety of manifestations include bleeding, intussusception, or polyp prolapse. In this study, we present an 8-month-old male infant of juvenile polyposis syndrome initially presenting with chronic anemia. To the best of our knowledge, this is the youngest case reported in the literature.

METHODS

We report a rare case of an 8-month-old male infant who presented with chronic anemia and gastrointestinal bleeding initially. Panendoscopy and abdominal computed tomography showed multiple polyposis throughout the entire alimentary tract leading to intussusception. Technetium-99m-labeled red blood cell (RBC) bleeding scan revealed the possibility of gastrointestinal tract bleeding in the jejunum. Histopathological examination on biopsy samples showed Peutz-Jeghers syndrome was excluded, whereas the diagnosis of juvenile polyposis syndrome was established.

RESULTS

Enteroscopic polypectomy is the mainstay of the treatment. However, polyps recurred and occupied the majority of the gastrointestinal tract in 6 months. Supportive management was given. The patient expired for severe sepsis at the age of 18 months.

CONCLUSION

Juvenile polyposis syndrome is an inherited disease, so it is not possible to prevent it. Concerning of its poor outcome and high mortality rate, it is important that we should increase awareness and education of the parents at its earliest stages.

Excision of Mullerian duct remnant for persistent Mullerian duct syndrome provides favorable short- and mid-term outcomes

OBJECTIVE

In dealing with persistent Mullerian duct syndrome (PMDS), excision of Mullerian duct remnant (MDR) has been rarely mentioned in the past, but recent discussions have taken place. This study aimed to evaluate the operative feasibility and outcomes.

MATERIALS AND METHODS

Three patients with PMDS operated on with excision of MDR between 2000 and 2009 were enrolled. Medical records were retrospectively collected and reviewed.

RESULTS

Bilateral undescended testis was manifested in all cases. Two patients presented with incarcerated hernia, requiring emergency herniorrhaphy at the ages of 6 months and 10 days, respectively. Reconstruction comprising simultaneous MDR excision and orchiopexy was made at the age of 1 year. MDR was incidentally found in another patient during operation for undescended testis. Immediate reconstruction was accomplished. Follow-up periods were 12.0, 3.5, and 2.5 years, respectively. Worse outcomes were noted on the two testes with repeated operations for incarcerated hernias, whereas the outcomes on the other four testes with a single operation were favorable.

CONCLUSIONS

Excision of MDR is technically feasible, and provides favorable outcomes in cases of a single operation. For experienced surgeons, immediate reconstruction should be the priority when this abnormality is incidentally encountered at an age suitable for orchiopexy.

Laparoscopy versus open surgery for idiopathic intussusception in children

PURPOSE

This study aims to compare the results of laparoscopy and open surgery for idiopathic intussusception in children as well as evaluate the efficacy of ileopexy.

METHODS AND MATERIALS

Between January 2007 and July 2013, children aged <18 years who were operated for intussusception in our institution were reviewed. Patients were classified into two groups, laparoscopy (LAP) and open (OPEN). Both groups were further divided into two subgroups, ileopexy (IP) and non-ileopexy (NIP). Parameters investigated included age, gender, operative indication, surgical procedure, type of intussusception, level of intussusceptum, presence of spontaneously reduced intussusception and pathologic lead points, operative time (OP time), time to oral intake (PO time), length of postoperative hospital stay (LOS), and surgical recurrence.

RESULTS

There were 23 and 35 patients in LAP and OPEN group, respectively. No significant difference was found on age, operative indication, surgical procedure, type of intussusception, level of intussusceptum, and presence of spontaneously reduced intussusception between both groups. In LAP group, mean OP time was significantly longer; mean PO time and LOS were significantly shorter. One surgical recurrence occurred in each group (p = 0.76). In comparison of LAP-IP (n = 15) and LAP-NIP (n = 8), OP time, PO time, and LOS were similar in both subgroups. One recurrence was noted in LAP-IP (p = 0.46). The overall conversion rate was 13.0 % (6.8 vs. 25 %, p = 0.21). Compared to patients with intussusceptum to ascending colon, the conversion rate was significantly higher in patients with intussusceptum to transverse and descending colon. With the exclusion of conversion, OP time was significantly shorter in LAP-NIP (p = 0.01).

CONCLUSION

Laparoscopy should be considered the primary modality for radiologically irreducible or recurrent idiopathic intussusception in children. Ileopexy provides no benefit on recurrence prevention but contributes to longer OP time.
