Review
INTRODUCTION
Pediatric digestive volvulus is a serious condition that carries with it a high rate of morbidity and mortality.
OBJECTIVE
This review highlights the pearls and pitfalls of pediatric digestive volvulus, including the presentation, diagnosis, and management in the emergency department (ED) based on current evidence.
DISCUSSION
Pediatric digestive volvulus is a deadly condition most commonly associated with malrotation. It occurs when the stomach or small intestine twists on itself, resulting in ischemia and potentially strangulation with necrosis and perforation. Presentation differs based on the gastrointestinal (GI) segment affected, degree of twisting, and acuity of the volvulus. Gastric volvulus most commonly presents with retching with or without nonbilious emesis and epigastric distension with pain, while midgut volvulus typically presents with bilious emesis in infants. Patients with GI necrosis and perforation may present with hemodynamic compromise and peritonitis. If suspected, emergent consultation with the pediatric surgery specialist is necessary, and if this is not available, transfer to a center with a pediatric surgeon is recommended. Imaging includes plain radiography, ultrasound, or upper GI series, while treatment includes resuscitation, administration of antibiotics, and emergent surgical decompression and detorsion of the involved segments.
CONCLUSION
An understanding of pediatric digestive volvulus and its many potential mimics can assist emergency clinicians in diagnosing and managing this deadly disease.

Mvolo County, an Onchocerciasis Endemic Area in Western Equatoria State, South Sudan: An Entomological Study to Prepare for a "Slash and Clear" Community-Based Vector Control Intervention.
BACKGROUND
Mvolo in Western Equatoria of South Sudan has been a hotspot for transmission since the 1940s. In Mvolo onchocerciasis is a disease of public health importance, associated with onchocerciasis-associated epilepsy including nodding syndrome.
METHODS
We conducted an entomological study to map the breeding sites of blackflies (Simulium damnosum, sens lato) on the river Naam, to allow the removal of vegetation from vector breeding sites, the "slash and clear". Three blackfly catching sites were established along the river. Focus group discussions were also conducted to assess the willingness of the communities to support the "slash and clear" intervention and the semi-annual distribution of ivermectin.
RESULTS
A total of 2466 female s.l. were caught in 14×11h (06.00-15.00) catches. The highest biting density of 4210.25 flies/month/h and monthly biting rate (MBR) of 11,482.25 bites/man/month were observed in November 2023. Biting density and MBR reduced to zero in the intervention site by April 2024. While the mean parity rate was 31% (CI: 0.2976±0.9176). Two diurnal biting peaks were observed, one from 9:00-10:00 (at the bridge site) and a prominent one from 14:00-15:00 in the two catching sites in Mvolo. Along the river Naam, only one site was found productive for s.l.; and the larvae and adults were morphologically associated with the anthropophilic . The "slash and clear" intervention was implemented at Dogoyabolu along the river Naam. Communities expressed willingness to support a "slash and clear" intervention and the semi-annual distribution of ivermectin.
CONCLUSION
active breeding was identified along the river Naam in a stretch of 3-5 km close to human settlements. Highest blackfly biting density was 4210.25 flies/month/h, and two fly biting peaks were observed. A community "slash and clear" vector control was implemented, and will be prospectively monitored.

BACKGROUND
Intra-abdominal lymphatic malformations (LMs) are relatively rare congenital anomalies and can be divided into intra- and retroperitoneal subgroups. This study aims to evaluate the outcomes after surgical resection of intraperitoneal LMs in children.
METHODS
The records of all patients ≤16 years of age with intraperitoneal LMs managed at our tertiary center between 2007-2022 were reviewed. Patients with retroperitoneal LMs were excluded. Our preferred approach is surgical exploration for large (>5 cm), symptomatic lesions if they are potentially resectable on imaging.
RESULTS
A total of 12 patients (10 males) were diagnosed with intraperitoneal LMs located in the small bowel mesentery or omentum at a median age of 6.6 (range, 0.6-14.4) years. Ten (83%) patients presented with acute symptoms, including abdominal pain (n = 8; 67%) and vomiting (n = 3; 25%). Two (17%) intraperitoneal LMs were found on imaging performed for other reasons. Surgical exploration was performed in 11/12 (92%) cases. Intestinal volvulus around a mesenteric macrocyst had occurred in 4 (36%) patients. Complete macroscopic resection was achieved in 10/11 (91%) patients. Most lesions were localized to a short intestinal segment. One mixed type LM with an extensive mesenteric involvement was biopsied as the lesion was deemed to be unresectable in preoperative imaging and the diagnosis was initially unclear. There was one recurrence (8%) during postoperative follow-up on imaging (median 3.6 (range, 1.5-6.9) years) but the patient has remained asymptomatic and not undergone interventions. 6/8 (75%) of screened intraperitoneal LMs were positive for a somatic PIK3CA mutation.
CONCLUSIONS
Most large, pedunculated macrocystic LMs in the small bowel mesentery or omental location were amenable to macroscopic resection. Intraperitoneal LMs tend to present with acute symptoms including a risk for intestinal volvulus based on anatomical location. Our results suggest low recurrence rates or need for further interventions over follow-up.

INTRODUCTION
Laparoscopic Nissen Fundoplication is an effective standard surgical procedure for treatment of severe GERD. While it is generally safe and effective, a rare but potentially fatal complication known as acute gastric volvulus can occur following this procedure.
CASE PRESENTATION
A 28-year-old male, ten months post Laparoscopic Nissen Fundoplication presented with a one-day history of severe epigastric pain, abdominal distention, unproductive retching, and difficulty in breathing. Examination revealed tachypnea, subcutaneous emphysema and a tender distended abdomen. Imaging studies showed a left pneumothorax, pneumoperitoneum, and a grossly distended stomach. Emergency exploratory laparotomy confirmed organoaxial gastric volvulus, necrosis of the greater curvature and gastric perforation. Partial gastrectomy and anterior gastropexy were performed. A left thoracostomy tube was placed to drain the left pneumothorax. He recovered fully post-operatively with complete resolution of all symptoms.
DISCUSSION
Acute Gastric volvulus post Laparoscopic Nissen Fundoplication is attributed to adhesions, gastrostomy tubes, and foreign bodies like sutures. Life-threatening complications, such as gastric perforation, can ensue, underscoring the need for swift diagnosis and treatment.
CONCLUSION
Acute gastric volvulus following Laparoscopic Nissen Fundoplication is a rare condition, and is difficult to diagnose. Given the steadily increasing rates of laparoscopic Nissen fundoplications performed in Uganda, maintaining a high index of suspicion is crucial for favorable patient outcomes among patients with this potentially fatal complication.

Introduction Congenital malformation studies serve several purposes, including establishing baseline rates, monitoring changes over time, exploring the origins of these defects, and helping in planning health services. Increasing public awareness about pediatric surgical interventions is another goal of these studies. However, the impact of congenital malformations is often underestimated in developing countries due to insufficient healthcare data and diagnostic facilities, particularly in rural areas. Families affected by the birth of a child with congenital malformations face significant stress and hardship. Methods The main aims of this study were to evaluate the clinical pattern of congenital structural malformations in our region (Uttarakhand, India), identify possibly associated factors of congenital malformations, and find out the immediate outcome of congenital malformations in enrolled participants. Results Among a total of 150 cases, 73 (48.7%) cases were inborn, whereas 77 (51.3%) cases were outborn. Investigation of congenital malformation revealed cleft lip or palate in 37 (24.7%) cases, congenital heart disease (CHD) in 33 (22%) cases, meningomyelocele (MMC) in 18 (12.0%) cases, anorectal malformation (ARM) in 11 (7.3%) cases, hypospadias in 10 (6.7%) cases, congenital talipes equinovarus (CTEV) in nine (6.0%) cases, tracheoesophageal fistula (TEF) in nine (6.0%) cases, polydactyly in seven (4.7%) cases, pelviureteric junction obstruction (PUJO) in four (2.7%) cases, duodenal atresia in three (2.0%) cases, midgut volvulus in three (2.0%) cases, umbilical sinus in two (1.3%) cases, sacrococcygeal teratoma (SCT) in one (0.7%) case, phimosis in one (0.7%) case, microtia in one (0.7%) case, and micrognathia in one (0.7%) case. Mortality was observed in 11 (7.3%) cases, whereas 105 (70%) cases were successfully discharged. Among 11 mortality cases, the cause of death was CHD in seven (63.2%) cases, TEF+CHD in two (18.1%) cases, MMC in one (9%) case, and duodenal atresia in one (9%) case. Conclusion Contrary to the common belief that advanced maternal age of greater than 35 years is a major cause, 86.6% of the congenital structural anomalies in our hospital-based study in Uttarakhand occurred in babies of mothers belonging to the age group of 18-30 years. Also, consanguineous marriage was observed in only 3.3% of cases, indicating that it may not be a major contributing factor causing congenital structural malformations in our region. External congenital anomalies are most commonly observed (60.7%), with cleft lip and cleft palate being the most common. The most frequently observed internal congenital anomaly is CHD (22%) followed by gastrointestinal (GI) (18.6%) and urinary anomalies (10.1%). Death and referral are commonly seen in CHD.

Patients with factor XIII (FXIII) deficiency present with a bleeding tendency that is difficult to diagnose because their coagulation test results are normal. We herein report a case of a 74-year-old male who presented to our hospital in cardiac arrest. After resuscitation, he was found to have sigmoid volvulus and necrosis; therefore, an emergency laparotomy was performed. Intraoperative findings revealed an extensive strangulated ileus in addition to sigmoid volvulus. We performed resection without reconstruction and maintained open abdominal management (OAM) for six days. After abdominal closure, the patient experienced postoperative bleeding four times from the mesenteric transection; three of the bleeding episodes required open hemostasis. Since he had mild coagulopathy during each bleeding episode, FXIII deficiency was suspected and diagnosed. After administration of FXIII concentrate, the tendency to intraoperative bleeding improved significantly. FXIII deficiency should be considered in cases of repeated severe bleeding, even when coagulation tests reveal no major abnormalities.

The torsion of a dilated sigmoid colon around its own mesenteric axis is the cause of sigmoid volvulus, which frequently results in constipation and intestinal obstruction. The clinical presentation of sigmoid volvulus can be observed as nausea, constipation, abdominal distension, and abdominal pain. It is also reported to be insidious. Additionally, it causes blood obstruction, resulting in necrosis, bowel ischemia, and even intestinal perforation if not addressed on time. Physical symptoms might vary depending on the course of the disease but are usually observed as the classical trio of abdominal distension, abdominal pain, and constipation. Computed tomography imaging presents the sign of an inverted U, or classic coffee bean, aiding in the diagnosis of the sigmoid volvulus. A 38-year-old male was admitted to the emergency department of our tertiary care center with significant complaints of obstipation and abdominal pain. The medical history and physical examination revealed peritoneal symptoms, which warranted a prompt radiological imaging diagnosis. The patient was subjected to computed tomography, which was suggestive of sigmoid volvulus. The patient underwent an emergency laparotomy and sigmoidectomy, which were uneventful with no postoperative complications.

Hirschsprung disease, a rare genetic disorder affecting the enteric nervous system, is characterized by the absence of ganglion cells in the myenteric plexus. Typically identified in neonates due to the failure to pass meconium, diagnosis beyond the first year of life is considered delayed. Common clinical manifestations in children with late-onset Hirschsprung disease include abdominal distension, abdominal pain, vomiting, fever, and abnormal bowel sounds. Sigmoid volvulus, though uncommon, can complicate Hirschsprung disease, potentially leading to misdiagnosis and severe complications such as intestinal perforation, hemorrhage, sepsis, and even mortality. Non-surgical interventions such as antibiotic therapy, intestinal decompression, and fluid resuscitation are preferred initial treatments to stabilize the patient. This case involves a 9-year-old boy who has presented with abdominal distension since birth and a lengthy history of irregular bowel habits. The diagnosis of Hirschsprung disease was confirmed at our institution, and the patient underwent a two-stage repair procedure, which was completed without any intraoperative or postoperative complications. The patient experienced an uneventful recovery, was discharged with stable vital signs, and regained normal bowel function. This case highlights the challenges of delayed diagnosis at nine years and underscores the importance of prompt management.

Gastric volvulus and wandering spleen are two rare and uncommon conditions. Gastric volvulus is characterized by the rotation of the stomach around itself, causing a closed obstruction. It was first described in the 19th century and is classified according to the axis, etiology, or chronicity. A wandering spleen is defined by the absence of one or all of the splenic ligaments, which occurs either for congenital or acquired reasons. An enlarged spleen may contribute to the wandering spleen and, in turn, lead to gastric volvulus and infarction of the stomach, requiring emergency surgical intervention. In this report, we present a case of a 19-year-old female who presented to the emergency department with severe abdominal pain and epigastric distension. After performing the necessary investigations, she was diagnosed with a wandering spleen and acute gastric volvulus. An immediate laparotomy was performed and both the spleen and the stomach were resected to save the patient's life at the right time.

We thank Prof. Atamanalp and colleagues for their interest and valuable comments on our article. The authors have highlighted important considerations in the diagnosis of sigmoid volvulus (SV). We would like to respond to their comments. Firstly, although we agree with their opinion that CT, MRI, and endoscopy are more reliable diagnostic tools than plain radiography, we still emphasize that diagnostic imaging for SV is initially based on plain radiography, as recommended by the WSES consensus guidelines. Since SV is the third most common cause of colonic obstruction worldwide, the accessibility of plain radiography is crucial. Among the many plain radiographic signs of SV, Levsky et al. reported that the most sensitive signs were absence of rectal gas, followed by inverted-U appearance and coffee bean sign. Understanding these signs may lead to early detection of SV and further CT evaluation for ischemia or perforation. Despite the high value of plain radiography, there is a global tend to use CT instead from the outset. Secondly, we agree with their opinion that endoscopy is not only a therapeutic, but also a diagnostic procedure to assess mucosal viability. In addition, we believe that endoscopy is also useful in ruling out other obstructive lesions, including colorectal neoplasia and complicated sigmoid diverticular disease. In the clinical setting, endoscopy is performed after the diagnosis of SV by plain radiography or CT and serves as the first line of decompression of SV when ischemia or perforation is not suspected. Finally, we congratulate Prof. Atamanalp and colleagues for their dedicated contribution to the large-scale SV studies in Eastern Anatolia, Turkey, where SV is endemic.
