GAPS phase II: development and pilot results of the global assessment in pediatric surgery, an evidence-based pediatric surgical capacity assessment tool for low-resource settings.

PURPOSE: Pediatric surgical care in low- and middle-income countries is often hindered by systemic gaps in healthcare resources, infrastructure, training, and organization. This study aims to develop and validate the Global Assessment of Pediatric Surgery (GAPS) to appraise pediatric surgical capacity and discriminate between levels of care across diverse healthcare settings. METHODS: The GAPS Version 1 was constructed through a synthesis of existing assessment tools and expert panel consultation. The resultant GAPS Version 2 underwent international pilot testing. Construct validation categorized institutions into providing basic or advanced surgical care. GAPS was further refined to Version 3 to include only questions with a > 75% response rate and those that significantly discriminated between basic or advanced surgical settings. RESULTS: GAPS Version 1 included 139 items, which, after expert panel feedback, was expanded to 168 items in Version 2. Pilot testing, in 65 institutions, yielded a high response rate. Of the 168 questions in GAPS Version 2, 64 significantly discriminated between basic and advanced surgical care. The refined GAPS Version 3 tool comprises 64 questions on: human resources (9), material resources (39), outcomes (3), accessibility (3), and education (10). CONCLUSION: The GAPS Version 3 tool presents a validated instrument for evaluating pediatric surgical capabilities in low-resource settings.

The outcome of esophageal perforation in neonates and its risk factors: a 10-year study.

PURPOSE: Esophageal perforation is a rare complication in infants that can be difficult to diagnose. The mortality rate due to esophageal perforation is high. This condition is more common in low birth weight premature infants. This study examines esophageal perforation in relation to various demographic and clinical variables. METHODS: This study has a cross-sectional design. All pre-term neonates with esophageal perforation at Valiasr Hospital in Tehran, Iran, were included in the study over the span of ten years, from 2011 to 2021. Factors, such as gestational age, sex, weight, type of delivery, and interventions performed that could contribute to the condition, including intubation and Orogastric (OG) tube insertion, were investigated in the participants. RESULTS: Among the 9924 infants studied over the 10-year period, 15 cases (0.15%) had esophageal perforation. All these infants underwent non-operative management with acceptable results. CONCLUSION:  Learning about the risk factors for iatrogenic esophageal perforation in neonates can help prevent this unwanted event in most cases. Also, the majority of these cases can be managed non-operatively provided that early diagnosis is made.

Multicenter Study of 342 Anorectal Malformation Patients: Age, Gender, Krickenbeck Subtypes, and Associated Anomalies.

INTRODUCTION: Published studies based on Krickenbeck classification of anorectal malformations (ARMs) are still insufficient to assess the global as well as regional relative incidence of different ARM subtypes, gender distribution, and associated anomalies. The primary purpose of this study was to provide an estimate of those in Global Initiative for Children's Surgery (GICS) research group. MATERIALS AND METHODS: We collected ARM data prospectively for 1 year from four institutes of different geographic locations. A total of 342 patients were included in this study (195, 126, 11, and 10 from Bangladesh, Iran, Papua New Guinea, and Oxford, United Kingdom, respectively). RESULTS: Overall male to female ratio was 1:1. The most frequent ARM subtype was perineal fistula (23.7% = 81/342). About 48.5% (166/342) patients had at least one associated anomaly. Cardiac and genitourinary systems were the most commonly affected systems, 31.6% (108/342) and 18.4% (63/342), respectively. These organ-systems were followed by anomalies of vertebral/spinal (9.9% = 34/342), musculoskeletal (4.4% = 15/342), and gastrointestinal/abdominal (3.2% = 11/342) systems. Rectovesical fistula had the highest percentage (96.4% = 27/28) of associated anomalies. About 18.1% (62/342) patients had multiple anomalies. ARMs (both isolated and with associated anomalies) occurred equally in males and females. Comparison between patients from Bangladesh and Iran showed differences in relative incidence in ARM subtypes. In addition, Iranian patient group had higher percentage of associated anomalies compared with Bangladeshi (73 vs. 35.4%). CONCLUSION: Our study provides important insights about ARM subtypes, gender distribution and associated anomalies based on Krickenbeck classification especially from Bangladesh and Iran.

Evaluation of the outcome of complete sinus excision with reconstruction of the umbilicus in patients with umbilical pilonidal sinus.

Umbilical pilonidal sinus is a cause of umbilical discharge. In this study, the outcome of complete excision of the umbilical sinus with umbilical reconstruction is considered. Adult patients with umbilical pilonidal sinus who had not undergone any previous surgeries were operated on using a technique that involves complete excision of the sinus after eversion of the umbilicus followed by reconstruction of the umbilicus. Patients were then followed; and wound complications, recurrence, and patient satisfaction were evaluated at postoperative visits. A total of 45 patients underwent the operation; 39 (86.5%) were male, and 6 (13.5%) were female. The mean age was 22.6 years (18-27 years). Six male patients had synchronous sacrococcygeal pilonidal disease. The mean follow-up period was 34 months (3-62 months). Only four patients had wound drainage after operation, and all required drainage of the wound. No recurrence was observed during the follow-up period, and all patients were satisfied with the appearance of their umbilicus. The technique of complete sinus excision and umbilical reconstruction is an effective and acceptable method for treating umbilical pilonidal sinus and may be recommended for primary treatment of this disease.

Colorectal carcinoma: a retrospective, descriptive study of age, gender, subsite, stage, and differentiation in Iran from 1995 to 2001 as observed in Tehran University.

PURPOSE: Colorectal carcinoma is one of the most common cancers in the world as well as in Iran. There are differences in subsite of the carcinoma when considering age and gender. This study was designed to describe the distribution of colorectal carcinoma by age at diagnosis, gender, and subsite of the tumor. These factors also are evaluated in conjunction with disease stage and tumor differentiation at the time of diagnosis. METHODS: Data from 419 patients from a population that receives no screening between April 1995 and March 2001 operated on in the Cancer Institute and Imam Khomieni Hospital with a diagnosis of colorectal cancer were used to describe distribution of the colorectal carcinoma by age, gender, tumor subsite and pathology, and stage at diagnosis. RESULTS: There were 403 (96.2 percent) cases of adenocarcinoma. Males and females constituted 52.4 and 47.6 percent of cases, respectively. The mean age was 52.3 years. Patients were divided into two age groups (40 years and younger, and older than 40 years); 16.4 percent of patients had tumors in the proximal colon and 83.6 percent in distal parts. Most patients were Stage II and III (48.1 and 33.4 percent, respectively). Tumor subsite distribution was almost the same between the two age groups (aged 40 years and younger: proximal, 18.5 percent, and distal, 81.5 percent; older than aged 40 years: proximal, 15.7 percent, and distal, 84.3 percent). Most patients in the younger age group were Stage III (45 percent) and in the older age group were Stage II (53.2 percent; P<0.001). Tumor differentiation proportions in patients aged 40 years and younger were: good, 24.4 percent; moderate, 53.6 percent; poor, 22 percent; and in patients older than aged 40 years were: good, 41.5 percent; moderate, 52.6 percent; poor, 5.9 percent (P<0.001). There were no differences in stage and tumor differentiation between two genders, but most of the patients with tumors in proximal colon were males (62.5 percent; P=0.1). CONCLUSIONS: Most of the colorectal carcinomas were in distal parts in our study, so most of these carcinomas can be detected by proctosigmoidoscopy. Because younger patients had more advanced disease, the importance of screening and "clinical suspicion" in the young is important.

Comparison of outcomes in Z-plasty and delayed healing by secondary intention of the wound after excision of the sacral pilonidal sinus: results of a randomized, clinical trial.

PURPOSE: Pilonidal sinus is a common disease, mostly among young males. Although the conventional surgery, secondary repair of the wound after wide excision with or without curettage, is not technically difficult, it takes a long time, weeks or months, for a wound to heal. In this study, we compared outcomes and complications of Z-plasty repair with outcomes and complications of delayed healing by secondary intention (conventional surgery). METHODS: In a randomized, clinical trial, we recruited 72 patients in each arm. All of the patients were operated on by a general surgeon and were followed up for variable periods. Patients in the Z-plasty arm were followed for a mean period of 22.01 months. Patients conventional surgery arm were followed for a mean period of 22.23 months. The main studied outcomes were healing of the wound and disease recurrence during the follow-up period. The main complications that were taken into account were bleeding, hematoma, infection, and recurrence. RESULTS: The two arms were comparable in the age and gender distributions, duration of disease, and history of any types of operations. The duration of hospitalization after the operation was shorter in the conventional surgery group (1.76+/-0.75 days vs. 2.86+/-0.73 days, P<0.001). However, wounds healed much faster in the Z-plasty group (15.4 vs. 41 days, P<0.001). Moreover, it took longer for patients in the conventional surgery group to return to normal activity (17.5 vs. 11.9 days, P<0.001). There was no difference in postoperative complications regarding bleeding, hematoma, infection, or recurrence during the follow-up period in two arms. CONCLUSIONS: Healing was considerably faster in patients who were treated with Z-plasty technique of wound closure. This procedure can be used as a desirable treatment for pilonidal sinus, which is a noncomplex method without increased rate of complications. Nonetheless, it might slightly increase the duration of hospitalization.
