RESUMO
PURPOSE: Acquired rectovaginal fistulae (RVF) are a complication of paediatric HIV infection. We report our experience with the surgical management of this condition. METHODS: We retrospectively reviewed the records of paediatric patients with HIV-associated RVF managed at Chris Hani Baragwanath Academic Hospital (2011-2023). Information about HIV management, surgical history, and long-term outcomes was collected. RESULTS: Ten patients with HIV-associated RVF were identified. Median age of presentation was 2 years (IQR: 1-3 years). Nine patients (9/10) underwent diverting colostomy, while one demised before the stoma was fashioned. Fistula repair was performed a median of 17 months (IQR: 7.5-55 months) after colostomy. An ischiorectal fat pad was interposed in 5/9 patients. Four (4/9) patients had fistula recurrence, 2/9 patients developed anal stenosis, and 3/9 perineal sepsis. Stoma reversal was performed a median of 16 months (IQR: 3-25 months) after repair. Seven patients (7/9) have good outcomes without soiling, while 2/9 have long-term stomas. Failure to maintain viral suppression after repair was significantly associated with fistula recurrence and complications (φ = 0.8, p < 0.05). CONCLUSION: While HIV-associated RVFs remain a challenging condition, successful surgical treatment is possible. Viral suppression is a necessary condition for good outcomes.

OBJECTIVE: Wound dehiscence after posterior sagittal anorectoplasty (PSARP) or anorectal vaginal urethroplasty (PSARVUP) for anorectal malformation (ARM) is a morbid complication. We present a novel anoplasty technique employing para-U-stitches along the anterior and posterior portions of the anoplasty, which helps buttress the midline U-stitch and evert the rectal mucosa. We hypothesized that, in addition to standardized pre- and postoperative protocols, this technique would lower rates of wound dehiscence. MATERIALS AND METHODS: A retrospective review of patievnts who underwent primary PSARP or PSARVUP with the para-U-stitch technique from 2015 to 2021 was performed. Wound dehiscence was defined as wound disruption requiring operative intervention within 30 days of the index operation. Superficial wound separations were excluded. Descriptive statistics were calculated. The final cohort included 232 patients. RESULTS: Rectoperineal fistula (28.9%) was the most common ARM subtype. PSARP was performed in 75% and PSARVUP in 25%. The majority were reconstructed with a stoma in place (63.4%). Wound dehiscence requiring operative intervention occurred in four patients, for an overall dehiscence rate of 1.7%. The dehiscence rate was lower in PSARPs compared with PSARVUPs (0.6 vs. 5.2%) and lower for reconstruction without a stoma compared with a stoma (1.2 vs. 2.0%). There were additional six patients (2.6%) with superficial wound infections managed conservatively. CONCLUSION: We present the para-U-stitch anoplasty technique, which is an adjunct to the standard anoplasty during PSARP and PSARVUP. In conjunction with standardized pre- and postoperative protocols, this technique can help decrease rates of wound dehiscence in this patient population.
RESUMO
In patients with anorectal malformations and a colostomy, the high-pressure distal colostogram is the technique of choice to determine the type of malformation and thus to plan the surgical repair. Perforations associated with high-pressure distal colostograms are very rare. The aim of our study was to identify pitfalls to prevent perforation secondary to high-pressure distal colostogram. The study included two male patients and was complicated with rectal perforations secondary to high-pressure distal colostogram. Both patients had an imperforate anus without a fistula. One patient had extraperitoneal rectal perforation with progressive contrast spillage into the peritoneum and demised. The other patient developed an extraperitoneal perforation and an associated necrotizing fasciitis of his perineum and scrotum, but he recovered well after debridement. Two further cases of rectal perforation have been described in the literature. Rectal perforation, although rare, is a described life-threatening complication secondary to high-pressure distal colostogram. The cause is excessive contrast pressure. Injection of contrast should be stopped once the distal end of the colon has a convex shape. Intraperitoneal perforation may cause hypovolemic/septic shock, and patients need to be appropriately resuscitated and should undergo laparotomy. Extraperitoneal perforation requires close monitoring for possible local complications, which may necessitate early debridement.
RESUMO
Perineal trauma is uncommon in the pediatric population and it is estimated that 5 to 21% is secondary to sexual abuse. We aim to present a proposed surgical technique to repair perineal injuries secondary to sexual assault in female children. The technique is based on the posterior sagittal anorectoplasty (PSARP) for repairing anorectal malformations and, between 2017 and 2019, it was used to treat three girls (2 months, 2 years, and 8 years of age) with fourth-degree perineal injuries secondary to sexual assault. One of them underwent laparotomy and Hartmann's colostomy for an acute abdomen. Two underwent wound debridement and suturing and only had a stoma fashioned at 5 days and 6 weeks posttrauma, respectively. The perineal repair was performed 2, 6, and 7 weeks postinjury and done as follows: with the child prone in jack-knife position, stay-sutures are placed on the common wall between the rectum and the vagina. Using a needle tip diathermy, a transverse incision is performed below the sutures lifting the anterior rectal wall up. Stay sutures are then positioned on the posterior wall of the vaginal mucosa. The incision between the walls is deepened until the rectum and the vagina are completely separated. The deep and superficial perineal body is then reconstructed using absorbable sutures and an anterior anoplasty and an introitoplasty are performed. The stoma in each was closed 6 weeks postreconstruction. At follow-up, now 1 year or more postrepair, all patients have an excellent cosmetic outcome and are fully continent for stools.
RESUMO
BACKGROUND/PURPOSE: To assess the number of patients seen at the colorectal clinic of a low-to-middle income-country with emphasis on their social circumstances. METHODS: Between January 2013 and December 2018 we recorded the number of visits to colorectal clinic. From February 2019 prospective data on patients with anorectal malformations (ARMs) focusing on their social conditions (type of housing and sanitation) and HIV-exposure were collected. RESULTS: At the clinic 452 visits were recorded in 2013, 608 in 2014, 904 in 2016, 1392 in 2017, and 1968 in 2018. The ARM cohort included 100 patients: at the time of delivery the HIV status of 74 mothers was negative, positive in 21, and unknown in 5. None of the HIV-exposed patients seroconverted to HIV positive (average follow-up:39â¯months). Seventy-four patients live in formal settlements, 23 in informal, and 3 in unknown type. Forty-six patients have inside toilets, 39 outside flushing toilets, 10 outside pit latrines, 2 community toilets, and 3 an unknown sanitation. CONCLUSIONS: The clinic work-load has increased during the past years. A significant proportion of our patients are HIV-exposed, do not live in formal houses and do not have inside toilets. Tailored strategies for a successful surgical plan and bowel management need to be implemented. LEVEL OF EVIDENCE: II.

BACKGROUND: Childhood mortality is high in low- and middle-income countries. Burns are one of the five leading causes of childhood injury mortality in South Africa (SA). While there is an abundance of literature on burns in the developed world, there are far fewer publications dealing with childhood mortality related to burns in Africa and SA. OBJECTIVE: To describe the mortality of children admitted to a dedicated paediatric burns unit, and investigate factors contributing to reducing mortality. METHODS: A retrospective review was performed of patients admitted to the Johnson and Johnson Paediatric Burns Unit, Chris Hani Baragwanath Academic Hospital, Johannesburg, SA, between May 2009 and April 2012. RESULTS: During the study period, 1 372 patients aged ≤10 years were admitted to the unit. There were 1 089 admissions to the general ward and 283 admissions to the paediatric burns intensive care unit (PBICU). The overall mortality rate was 7.9% and the rate for children admitted to the PBICU 29.3%; 90.8% of deaths occurred in children aged ≤5 years. Of children admitted with an inhalational injury, 89.5% died. No child with a burn injury >60% of total body surface area (TBSA) survived. CONCLUSIONS: Our overall mortality rate was 7.9%, and the rate declined significantly over the 3-year study period from 11.7% to 5.1%. Age ≤5 years, the presence of inhalational injury, burn injury >30% of TBSA and admission to the PBICU were significant risk factors for mortality.
