RESUMO
BACKGROUND: The JPLT3-S (Japanese Study Group for Pediatric Liver Tumors-3) study, conducted cisplatin (CDDP) monotherapy for young children (<3 years old) with standard-risk hepatoblastoma (HB) using a central review system in Japan. In the previous JPLT2 study, cases with resectable tumors without any annotation factors in the PRETEXT (PRETreatment EXTent of disease) classification (standard-risk HB) showed favorable outcomes with treatment consisting of CDDP and pirarubicin, but showed toxicities and late complications. In the JPLT3-S trial, a less intense regimen consisting of CDDP alone was evaluated. METHODS: Patients who were less than 3 years of age and with PRETEXT I, II, or III HB without any annotation factors (e.g., E1, E1a, E2, E2a, H1, N1, P2, P2a, V3, and V3a) were eligible for inclusion in this study. In this trial, the central radiological and pathological features of all patients were reviewed. The primary outcome was the 3-year progression-free survival (PFS). RESULTS: A total of 38 patients (23 female) were included. The median patient age was 12 months (range: 2-34). Two patients discontinued treatment because of progressive disease, and five patients discontinued treatment for other reasons. The 3-year PFS rate was 93.9% (95% confidence interval [CI]: 86.4%-100%). All 38 patients survived (follow-up period 38-98 months), and the OS rate was 100% (CI: 100). Eighteen of the 38 patients (47.4%) experienced ototoxicity as a late complication. CONCLUSION: CDDP monotherapy regimen is feasible in young patients with localized HB, as classified by a central review.
RESUMO
This study investigates the long-term outcomes of palliative and definitive surgeries for esophageal atresia (EA) in patients with trisomy 18 syndrome. A retrospective study included 25 cases undergoing EA surgery at our center between 2008 and 2022. The Palliative group (n = 16) comprised 13 cases with esophageal banding and 3 with tracheoesophageal fistula (TEF) division. The Definitive group (n = 9) included 5 cases with primary repair and 4 with staged repair following TEF division. The patient characteristics exhibited no significant differences between the groups. In the Definitive group, 56% (5/9) were successfully weaned off mechanical ventilation, compared with none in the Palliative group (p = 0.002). Survival-to-discharge rates were 31% (5/16) in the Palliative group and 67% (6/9) in the Definitive group. Home ventilator management was required for all 5 cases that required ventilation in the Palliative group, whereas only 17% (1/6) in the Definitive group needed it. The Palliative group also required continuous oral suction for persistent saliva removal, with two cases undergoing laryngotracheal separation. Overall, definitive surgery for EA in patients with trisomy 18 syndrome may provide enhanced respiratory stability, thereby improving the survival-to-discharge rate and overall quality of life for patients and their families.
RESUMO
PURPOSE: Long-term outcomes of slide tracheoplasty in patients with congenital tracheal stenosis (CTS) have rarely been reported. This study aimed to clarify the long-term outcomes of CTS after slide tracheoplasty. METHODS: The medical records of 33 patients who underwent slide tracheoplasty for CTS at our institution between January 2005 and July 2018, with a follow-up duration > 5 years, were retrospectively reviewed. Patients' characteristics, perioperative condition, operative management, postoperative course, tracheal stenosis rates and growth data, were collected from medical records. RESULTS: The median operative age, minimum tracheal diameter, length of stenosis, duration of hospital stays, and follow-up duration were 8 months, 2.4 mm, 35 mm, 39 days, and 90 months, respectively. One patient died of bleeding in the right lung at 126 months postoperatively. Among the 10 patients requiring postoperative tracheostomy, seven were successfully decannulated at a median of 65 months postoperatively. Tracheal stenosis rates improved postoperatively and were subsequently maintained. Growth impairment and psychomotor delay were observed in 9 and 16 patients, respectively with significant differences found only in cases with genetic abnormalities and not in tracheal stenosis severity. CONCLUSION: Slide tracheoplasty for CTS leads to favorable long-term outcomes. However, various associated anomalies may influence growth and psychomotor development, emphasizing the importance of adequate support.

PURPOSE: To develop a predictive score for small diaphragmatic defects in infants with congenital diaphragmatic hernia (CDH) for determining thoracoscopic surgery indication. METHODS: The Japanese CDH Study Group cohort was randomly divided into derivation (n = 397) and validation (n = 396) datasets. Using logistic regression, a prediction model and weighted scoring system for small diaphragmatic defects were created from derivation dataset and validated with validation dataset. RESULTS: Six weighted variables were selected: no hydramnios, 1 point; 1 min Apgar score of 5-10, 1 point; apex type of the lung (left lung is detected radiographically in apex area), 1 point; oxygenation index < 8, 1 point; abdominal nasogastric tube (tip of the nasogastric tube is detected radiographically in the abdominal area), 2 points; no right-to-left flow of ductus arteriosus, 1 point. In validation dataset, rates of small diaphragmatic defects for Possible (0-3 points), Probable (4-5 points), and Definite (6-7 points) groups were 36%, 81%, and 94%, respectively (p < 0.001). Additionally, sensitivity, specificity, positive predictive value, and C statistics were 0.78, 0.79, 0.88, 0.76, and 0.45, 0.94, 0.94, 0.70 for Probable and Definite groups, respectively. CONCLUSION: Our scoring system effectively predicted small diaphragmatic defects in infants with CDH.

PURPOSE: This study aimed to evaluate prenatal predictors of mortality in fetuses with congenital diaphragmatic hernia (CDH). METHODS: A systematic literature search was performed to identify relevant observational studies that evaluated the ability of lung-to-head ratio (LHR), observed-to-expected LHR (o/e-LHR), observed-to-expected total fetal lung volume (o/e-TFLV), lung-to-thorax transverse area ratio (L/T ratio), intrathoracic herniation of the liver and the stomach, and side of diaphragmatic hernia, using a threshold for the prediction of mortality in fetuses with CDH. Study quality was assessed using the QUADAS-2 tool. Hierarchical summary receiver operating characteristic curves were constructed. RESULTS: A total of 50 articles were included in this meta-analysis. The QUADAS-2 tool identified a high risk of bias in more than one domain scored in all parameters. Among those parameters, the diagnostic odds ratio of mortality with o/e-LHR < 25%, o/e-TFLV < 25%, and L/T ratio < 0.08 were 11.98 [95% confidence interval (CI) 4.65-30.89], 11.14 (95% CI 5.19-23.89), and 10.28 (95% CI 3.38-31.31), respectively. The predictive values for mortality were similar between the presence of liver herniation and retrocardiac fetal stomach position. CONCLUSIONS: This systematic review suggests that o/e-LHR, o/e-TFLV, and L/T ratio are equally good predictors of neonatal mortality in fetuses with isolated CDH.

PURPOSE: The prenatal diagnosis of the stomach position in congenital diaphragmatic hernia (CDH) has been a reliable prognostic factor, but few studies have focused on the postnatal position. We therefore evaluated the significance of the nasogastric (NG) tube position just after birth. METHODS: The Japanese CDH Study Group database enrolled 1037 CDH neonates over 15 years. In our multicenter retrospective study, 464 cases of left-sided isolated CDH with prenatal diagnoses were divided into two groups: NG tube below the diaphragm (BD; n = 190) or above the diaphragm (AD; n = 274). The primary outcome was the 90-day survival rate, and the secondary outcomes were mechanical ventilation duration, hospitalization duration, and recurrence rate. RESULTS: The BD group had a significantly higher 90-day survival rate (98.4 vs. 89.4%, p < 0.001), shorter mechanical ventilation (11 vs. 19 days, p < 0.001), shorter hospitalization (38 vs. 59 days, p < 0.001), and lower recurrence rate (p = 0.002) than the AD group. A multivariate analysis showed that BD (adjusted odds ratio, 3.68; 95% confidence interval 1.02-13.30) was a favorable prognostic factor for the 90-day survival. CONCLUSION: The assessment of the NG tube position revealed it to be a reliable prognostic factor of left-sided isolated CDH. Therefore, it should be included as a routine assessment.

In the JPLT3 study, a real-time central surgical reviewing (CSR) system was employed aimed at facilitating early referral of candidates for liver transplantation (LTx) to centers with pediatric LTx services. The expected consequence was surgery, including LTx, conducted at the appropriate time in all cases. This study aimed to review the effect of CSR on institutional surgical decisions in cases enrolled in the JPLT3 study. Real-time CSR was performed in cases in which complex surgeries were expected, using images obtained after two courses of preoperative chemotherapy. Using the cloud-based remote image viewing system, an expert panel consisting of pediatric and transplant surgeons reviewed the images and commented on the expected surgical strategy or the necessity of transferring the patient to a transplant unit. The results were summarized and reported to the treating institutions. A total of 41 reviews were conducted for 35 patients, and 16 cases were evaluated as possible candidates for LTx, with the treating institutions being advised to consult a transplant center. Most of the reviewed cases promptly underwent definitive liver surgeries, including LTx per protocol.
RESUMO
BACKGROUND: The SIOPEL-4 study has demonstrated that dose-dense cisplatin-based chemotherapy dramatically improves outcome in children with high-risk hepatoblastoma in western countries. However, the feasibility and safety of this regimen have not been clarified in Japanese patients. METHODS: A pilot study, JPLT3-H, was designed to evaluate the safety profile of the SIOPEL-4 regimen in Japanese children with newly diagnosed hepatoblastoma with either metastatic disease or low alpha-fetoprotein. RESULTS: A total of 15 patients (three female) were enrolled. Median age was 2 years (range, 0-14). Three patients were PRETEXT II (where PRETEXT is PRETreatment EXTent of disease), six PRETEXT III, and six PRETEXT IV. All patients had lung metastasis, none had low alpha-fetoprotein. Eight patients completed the prescribed treatment, and seven patients discontinued therapy prematurely, four due to progressive disease and three due to causes other than severe toxicity. Grade 4 neutropenia was documented in most patients in preoperative cycles A1-3 (11/15 in A1, 9/11 in A2, and 7/11 in A3) and in all considering all cycles. Grade 3-4 thrombocytopenia and grade 3 anemia were also frequently observed. Patients experienced several episodes of grade 3 febrile neutropenia, but none had grade 4 febrile neutropenia or severe infections. One patient had grade 3 heart failure only in the first cycle. Other grade 3 or 4 toxicities were hypomagnesemia, anorexia, nausea, mucositis, liver enzyme elevation, fever, infection, and fatigue. There were no unexpected severe toxicities. CONCLUSION: The toxicity profile of JPLT3-H was comparable to that of SIOPEL-4. Dose-dense cisplatin-based chemotherapy may be feasible among Japanese patients with high-risk hepatoblastoma.

PURPOSE: Predicting lethal pulmonary hypoplasia in infants with congenital diaphragmatic hernia (CDH) before extracorporeal membrane oxygenation (ECMO) initiation is difficult. This study aimed to predict lethal pulmonary hypoplasia in patients with CDH prior to ECMO. METHODS: This was a multicenter cohort study involving neonates prenatally diagnosed with isolated unilateral CDH (born 2006-2020). Patients who required ECMO due to respiratory insufficiency were included in this study. Patients who underwent ECMO due to transient disorders were excluded from analysis. Blood gas analysis data within 24 h of birth were compared between survivors and non-survivors. Predictive abilities were assessed for factors with significant differences. RESULTS: Overall, 34 patients were included (18 survivors and 16 non-survivors). The best pre-ductal PaO2 was significantly lower in non-survivors than in survivors (50.4 [IQR 30.3-64.5] vs. 67.5 [IQR 52.4-103.2] mmHg, respectively; p = 0.047). A cutoff PaO2 of 42.9 mmHg had a sensitivity, specificity, and positive predictive value of 50.0%, 94.4%, and 88.9%, respectively, to predict mortality. CONCLUSION: The best PaO2 within 24 h after birth predicted mortality following ECMO initiation. This should be shared to families and caregivers to optimize the best interests of the infants with CDH.

PURPOSE: We compared the efficacy of thoracoscopic repair (TR) with that of open repair (OR) for neonatal congenital diaphragmatic hernia (CDH). METHODS: The subjects of this multicenter retrospective cohort study were 524 infants with left-sided isolated CDH, diagnosed prenatally, and treated at one of 15 participating hospitals in Japan between 2006 and 2018. The outcomes of infants who underwent TR and those who underwent OR were compared, applying propensity score matching. RESULTS: During the study period, 57 infants underwent TR and 467 underwent OR. Ten of the infants who underwent TR required conversion to OR for technical difficulties and these patients were excluded from the analysis. The survival rate at 180 days was similar in both groups (TR 98%; OR 93%). Recurrence developed after TR in 3 patients and after OR in 15 patients (TR 7%, OR 3%, p = 0.40). The propensity score was calculated using the following factors related to relevance of the surgical procedure: prematurity (p = 0.1), liver up (p < 0.01), stomach position (p < 0.01), and RL shunt (p = 0.045). After propensity score matching, the multivariate analysis adjusted for severity classification and age at surgical treatment revealed a significantly shorter hospital stay (odds ratio 0.50) and a lower incidence of chronic lung disease (odds ratio 0.39) in the TR group than in the OR group. CONCLUSIONS: TR can be performed safely for selected CDH neonates with potentially better outcomes than OR.

PURPOSE: Few reports have determined the efficacy of olive oil enemas for severe constipation. Here, we review our experience with olive oil enemas in children with severe chronic constipation. METHODS: In our outpatient pediatric surgery department, the charts of 118 patients prescribed with olive oil enemas between January 2010 and November 2019 were retrospectively reviewed. A 1-2 ml/kg olive oil enema was given either alone or followed several hours later by a glycerin enema. Ratings included "very effective (VE)," "effective (E)," "limited (L)," "ineffective (I)," and "unknown (U)." RESULTS: One hundred and fifteen (97.5%) patients were able to use olive oil enemas at home. Forty-nine had functional constipation; 43 had anorectal malformation; 40 had Hirschsprung disease; 12 had spina bifida; and 10 had other maladies. Used as an enema, olive oil was effective in treating fecal impaction in 77.6% of patients; as a lubricant, it was effective in treating 76.9% of patients. Efficacy for fecal disimpaction was similar among patients with different underlying disorders. CONCLUSION: Olive oil enemas are useful for more than three-quarters of children with severe chronic constipation. Further study is warranted to add olive oil enemas as an adjunctive treatment in the management of severe constipation.

BACKGROUND/PURPOSE: There is no consensus on treatment strategy of congenital esophageal stenosis (CES). This study aimed to assess appropriateness of the treatment we have provided to patients with CES over the past four decades. METHODS: We carried out a retrospective chart review of 83 CES patients treated at three children's hospitals between 1973 and 2015. Each patient underwent an initial treatment with either surgery or a series of dilation that was followed by surgery if dilation failed to improve esophageal transit. Demographic data, course of treatment, outcomes, and complications were analyzed. RESULTS: During this initial treatment, 19 and 64 patients underwent surgery and dilation, respectively. Out of the 64 patients who underwent dilations as an initial treatment, 26 patients eventually required surgery. Out of all patients who required surgery (19 initial treatments + 26 failed dilations), 29 had tracheobronchial remnants and 16 had fibromuscular hypertrophy. Six patients experienced esophageal perforation during dilation and ten experienced anastomotic leakage after surgery. No patients had swallowing difficulties at the latest follow up, 141(9-324) months. CONCLUSIONS: Dilation is recommended as an initial therapy, especially if histological diagnosis of CES is uncertain. Persistent swallowing difficulties after 2 series of dilation may be an indication for surgery. LEVELS OF EVIDENCE: level IV.

PURPOSE: To date, there is no compelling evidence of the optimal timing of surgery for congenital diaphragmatic hernia (CDH). This study aimed to establish the optimal timing of surgery in neonates with isolated left-sided CDH. METHODS: This multicenter cohort study enrolled 276 patients with isolated left-sided CDH at 15 institutions. Based on the timing of surgery, the patients were classified into four groups [< 24 h (G1), 24-47 h (G2), 48-71 h (G3), and ≥ 72 h (G4)]. The clinical outcomes were compared among the groups using a logistic regression model, after adjusting for potential confounders, such as disease severity. RESULTS: Multivariate analyses showed that G2 also had a lower mortality rate than the other groups. In mild and severe cases, there were no significant differences in mortality across the four groups. In moderate cases, G2 resulted in significantly increased survival rates, compared with G1. CONCLUSION: The study results suggest that surgery within 24 h of birth is not recommended for patients with moderate severity CDH, that there is no benefit in the delay of surgery for more than 72 h in mild severity CDH patients, and that there is no definite optimal time to perform surgery in severe cases of CDH.

OBJECTIVE: To determine the appropriate initial ventilatory mode for neonatal congenital diaphragmatic hernia (CDH) by comparing patient prognosis following conventional mechanical ventilation (CMV) versus high-frequency oscillatory ventilation (HFO). STUDY DESIGN: This multicenter retrospective cohort study was performed at 15 participating hospitals in Japan between 2011 and 2016. The 328 eligible CDH infants were classified into CMV (n = 78) and HFO groups (n = 250) to compare mortality and incidence of bronchopulmonary dysplasia (BPD). Propensity score matching was applied to reduce confounding by indication. RESULT: While crude mortality was significantly higher in the HFO than the CMV group, adjusted odds ratio (OR) did not show significant difference in mortality between groups (OR of HFO group: 0.98, 95% confidence interval (CI): 0.57-1.67). Adjusted OR of BPD incidence showed no significant difference between groups (OR of HFO group: 1.66, 95%CI: 0.50-5.49). CONCLUSION: Initial ventilatory mode in CDH patients, whether CMV or HFO, does not affect prognosis.

PURPOSE: We report here the outcomes and late effects of the Japanese Study Group for Pediatric Liver Tumors (JPLT)-2 protocol, on the basis of cisplatin-tetrahydropyranyl-adriamycin (CITA) with risk stratification according to the pretreatment extent of disease (PRETEXT) classification for hepatoblastoma (HB). PATIENTS AND METHODS: From 1999 to 2012, 361 patients with untreated HB were enrolled. PRETEXT I/II patients were treated with up-front resection, followed by low-dose CITA (stratum 1) or received low-dose CITA, followed by surgery and postoperative chemotherapy (stratum 2). In the remaining patients, after 2 cycles of CITA, responders received the CITA regimen before resection (stratum 3), and nonresponders were switched to ifosfamide, pirarubicin, etoposide, and carboplatin (ITEC; stratum 4). Intensified chemotherapeutic regimens with autologous hematopoietic stem-cell transplantation (SCT) after resection were an optional treatment for patients with refractory/metastatic disease. RESULTS: The 5-year event-free and overall survival rates of HB patients were 74.2% and 89.9%, respectively, for stratum 1, 84.8% and 90.8%%, respectively, for stratum 2, 71.6% and 85.9%%, respectively, for stratum 3, and 59.1% and 67.3%%, respectively, for stratum 4. The outcomes for CITA responders were significantly better than those for nonresponders, whose outcomes remained poor despite salvage therapy with a second-line ITEC regimen or SCT. The late effects, ototoxicity, cardiotoxicity, and delayed growth, occurred in 61, 18, and 47 patients, respectively. Thirteen secondary malignant neoplasms (SMNs), including 10 leukemia, occurred, correlating with higher exposure to pirarubicin and younger age at diagnosis. CONCLUSION: The JPLT-2 protocol achieved up-front resectability in PRETEXT I/II patients with no annotation factors, and satisfactory survival in patients who were CITA responders in the remaining patients. However, outcomes for CITA nonresponders were unsatisfactory, despite therapy intensification with ITEC regimens and SCT. JPLT-2 had a relatively low incidence of cardiotoxicity but high rates of SMNs.

PURPOSE: This study aimed to elucidate the clinical characteristics of neonates with congenital diaphragmatic hernia (CDH) associated with pneumothorax and evaluate the risk factors for the development of pneumothorax. METHODS: A retrospective cohort study was conducted in the 15 institutions participating in the Japanese CDH Study Group. A total of 495 neonates with isolated CDH who were born between 2011 and 2018 were analyzed in this study. RESULTS: Among the 495 neonates with isolated CDH, 52 (10.5%) developed pneumothorax. Eighteen (34.6%) patients developed pneumothorax before surgery, while 34 (65.4%) developed pneumothorax after surgery. The log-rank test showed that the cumulative survival rate was significantly lower in patients with pneumothorax than in those without pneumothorax. Univariate analysis revealed significant differences between patients with pneumothorax and those without pneumothorax with regard to the best oxygenation index within 24 h after birth, mean airway pressure (MAP) higher than 16 cmH2O, diaphragmatic defect size, and need for patch closure. Multiple logistic regression analysis indicated that only the MAP was associated with an increased risk of pneumothorax. CONCLUSIONS: The cumulative survival rate was significantly lower in isolated CDH patients with pneumothorax than in those without pneumothorax. A higher MAP was a risk factor for pneumothorax in CDH patients.

PURPOSE: The management of subglottic stenosis (SGS) remains challenging. Although laryngotracheal reconstruction with a costal cartilage graft (LTR) has been widely performed, restenosis with cicatricial tissue may require long-term stenting, especially in patients with severe SGS. An anterior cricoid split (ACS) with long-term stenting has been shown to be useful for patients with mild SGS. Thus, we evaluated the clinical outcomes of patients, including severe SGS, who underwent ACS compared to those with LTR. METHODS: A retrospective chart review was conducted in 25 patients with severe SGS (Grades III and IV) who underwent initial laryngoplasty (ACS or LTR) in our hospital from January 2009 to April 2018. RESULTS: 17 patients (8 with Grade III and 9 with Grade IV) underwent ACS, and 8 (6 with Grade III and 2 with Grade IV) underwent LTR. The median duration of stenting was 11 months (range: 0.8-50) in the ACS group and 12 months (range: 0.4-29) in the LTR group. Thirteen of 17 patients (76.5%) in the ACS group were decannulated, whereas 4 of 8 patients (50%) in the LTR group were decannulated (p = 0.2). CONCLUSION: ACS might be useful even for children with severe SGS. The optimal duration of stenting should be investigated further.

Simultaneous repair of congenital tracheal and cardiovascular lesions remains challenging in small patients. We describe two infants weighing less than 3 kg who underwent successful tracheoplasty with concomitant correction of complex heart anomalies. In both operations, cardiopulmonary bypass was switched to extracorporeal membrane oxygenation after cardiac repair to optimize hemostatic function with transfusion and maintain activated clotting time at 200 to 240 seconds. Slide tracheoplasty was performed in a bloodless field, which prevented intraoperative hemorrhage from running down the divided lower trachea into the lung and causing airway obstruction. Both patients were weaned from extracorporeal support during surgery and extubated within 9 days.

INTRODUCTION: We aimed to establish and validate a risk score for fetuses with congenital diaphragmatic hernia (CDH) using only prenatal ultrasound findings. MATERIAL AND METHODS: Derivation (2011-2016, n = 350) and validation (2006-2010, n = 270) cohorts were obtained from a Japanese CDH study group database. Using a logistic regression analysis, we created a prediction model and weighted scoring system from the derivation dataset and calculated the odds ratio of an unsatisfactory prognosis (death within 90 days of life or hospitalization duration exceeding 180 days). Five adverse prognostic factors obtained using prenatal ultrasound, including an observed/expected lung area-to-head circumference ratio (o/eLHR) <25%, liver herniation occupying more than one-third of the thoracic space, thoracic stomach, right-side CDH, and severe malformations, were used as predictors. The obtained model was validated using the validation cohort. RESULTS: The unsatisfactory prognosis prediction model was obtained based on the adjusted odds ratios. The C statistics of the model were 0.83 and 0.80 in the derivation and validation datasets, respectively. The five variables were weighted proportionally to their adjusted odds ratios for an unsatisfactory prognosis (o/eLHR <25%, 1 point; liver herniation occupying more than one-third of the thoracic space, 1 point; thoracic stomach, 1 point; right-side CDH, 2 points; and severe malformations, 3 points). Unsatisfactory prognosis rates for the low- (0-2 points), intermediate- (3-5 points), and high-risk (6-8 points) groups were 17, 46, and 100%, respectively (p < 0.001), in the validation cohort. CONCLUSION: Our simple risk score effectively predicted the prognosis of fetuses with CDH.

PURPOSE: The aim of this study was to investigate risk factors for recurrence in the perineal canal (PC). METHODS: Patients with PC who underwent operations were enrolled in this study and were divided into recurrence and non-recurrence groups. Preoperative infection, the age at the operation, the presence of colostomy and the treatment procedure for fistula were retrospectively investigated. Regarding the treatment procedure for fistula, either closure of the rectal wall with stitches or ligation of fistula in the rectum was performed. These factors were compared between the two groups. RESULTS: Six of 17 patients with PC who underwent surgical treatment had recurrence. There were no significant differences in the incidence of preoperative infection, age at operation or presence of colostomy (p = 0.60, 0.38, 1.00, respectively). In the recurrence group, all patients were treated by closure of the rectal wall. In the non-recurrence group, five were treated by the closure of the rectal wall with stitches and six by ligation of the fistula. There was a significant association between recurrence and the treatment procedure for fistula (p = 0.04). CONCLUSION: Closure of the rectal wall with stitches is a risk factor for the recurrence of PC.
