Case Report: Cola Can Stay-Tab Ingestion in an 8-Year-Old Boy

Foreign body ingestion is a common problem in children. The most commonly ingested objects are coins, toy parts, bones, pins, and disc batteries. The radiolucency of the pull-tabs or stay-tabs of Cola cans constitutes another difficulty. In cases with ingested Cola can stay-tabs, as was in our patient, diagnosis should be confirmed at least by oesophagogram to avoid potential complications.

Pyosalpinx and hydrosalpinx in virginal adolescents: report of two cases

Pyosalpinx and hydrosalpinx are conditions mainly seen in adult women, but also among sexually active adolescents and can bring added hazard to fertility. However these conditions are very rare in childhood, as well as in adolescent girls who are not sexually active. We are presenting two rare cases of young girls in early puberty with hydrosalpinx and pyosalpinx. Both girls had a history of abdomino-pelvic surgery in childhood for congenital bowel anomalies and fecal incontinence. Such cases are good reminders that girls with known abdomino-pelvic anomalies and surgical procedures in childhood need long term follow-up, in particular when entering puberty and maturation. The two cases show how fallopian tubes can be indirectly affected and present in adolescence with serious problems needing surgical procedures and potentially threatening future reproductive system performances.

Sequential cytokine levels in the diagnosis of appendicitis

OBJECTIVE

To determine the diagnostic value of sequential white blood cell count (WBC), tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) in patients with abdominal pain.

MATERIAL AND METHODS

Tests were determined at hospital admission and 6 h later in 105 children. Patients who were non-operatively followed and had a normal histopathology were classified as the non-appendicitis (NA) group. Patients with symptoms consistent with appendicitis were classified as the appendicitis group (A). Data were analyzed as positive/negative predictive value, sensitivity, specificity and accuracy rate (AR). The global power of the variables in discriminating the patients between the two groups and advanced/simple appendicitis was assessed from the area under the receiver operating characteristic (ROC).

RESULTS

Initial measurements showed WBC to be a valuable diagnostic tool in acute appendicitis (AR = 74 %), whereas IL-6 and TNF-alpha were found not to be valuable. The second measurements revealed higher values, and IL-6 reached its highest AR (89 %). When initial values were evaluated in combination, the highest AR of 73 % was observed with TNF-alpha + WBC. The highest AR (90 %) was seen with IL-6 + TNF-alpha in the second measurements. ROC analysis showed WBC to be the most valuable parameter of the three. The area under the curve (AUC) was 0.750 for the initial measurement and 0.779 for the repeat measurement of WBC (p = 0.001). The most useful diagnostic parameter in discriminating between the simple and the advanced cases was IL-6 as assessed with the ROC curve (p<0.01).

CONCLUSIONS

WBC elevation in patients with suspected acute appendicitis is an important parameter supporting the diagnosis at initial admission, whereas IL-6 is a more valuable tool in diagnosing advanced appendicitis.

Effects of different suture materials on wound healing and infection in subcutaneous closure techniques

BACKGROUND

In this study we aimed to investigate the effects of different suture materials on wound healing and infection in subcutaneous closure techniques.

MATERIALS AND METHODS

Twenty-nine rats were randomly allocated to 5 groups. All subjects received 2-cm vertical dermal and subdermal incisions on their backs under sterile and proper surgical conditions. The subdermal cuts were then closed with vicryl (polyglycolic acid), biosyn (monofilament glycomer), prolene (polypropylene) and tissue adhesive (2-octylcyanoacrylate). After 10 days, all sutured areas were examined for seroma, haematoma formation and cosmetic outcome. The incisional lines were excised with 1-cm-wide skin strips and tissue hydroxyproline levels were determined. The specimens obtained were evaluated for the presence of giant cells, mononuclear cells, fibrosis and neutrophils.

RESULTS

No differences in tissue hydroxyproline levels were found between any of the suture materials used. Fibrotic process and inflammatory cell infiltration were more prominent in the biosyn and prolene groups than in other groups. Foreign body giant cells were observed in the biosyn group.

CONCLUSION

Vicryl and tissue adhesive should be preferred in subcutaneous closure techniques.

Association of tumor necrosis factor, interleukin-6 and cyclooxygenase pathway with lipopolysaccharide-induced intussusception

INTRODUCTION

Many factors and mechanisms have been proposed as causes for intussusception (IN); however, the etiology remains unclear. Inflammatory mediators such as tumor necrosis factor (TNF) and interleukin-6 (IL-6), which are elevated during infectious diseases, can significantly affect gastrointestinal motility. Motility changes caused by these agents might contribute to the development of IN. The aim of this experimental study was to determine the preventive effects of indomethacin on lipopolysaccharide (LPS)-induced IN in mice and to investigate the role of TNF and IL-6 on intussusception.

MATERIALS AND METHODS

Seventy-eight mice were divided into five groups. In the Control group (n=6), no procedure was done. In the Sham group (n=6), 1 ml saline, in the Indomethacin group (n=6), 10 mg/kg of indomethacin, in the LPS group (n=30), 12 mg/kg of LPS was administered intraperitoneally (IP). In the Treatment group (n=30), 10 mg/kg of indomethacin was administered IP following 12 mg/kg of LPS. All animals were laparotomized 6 hours following IP injections. The existence of IN was noted and blood specimens were obtained. TNFalpha and IL-6 plasma level measurements were performed by standard ELISA for mice. The results were compared using the Mann-Whitney U test and one-way ANOVA test. A value of p<0.05 was considered significant.

RESULTS

Five mice (1 in the control, 2 in the LPS, 2 in the Treatment group) were excluded from the study. IN was observed in 6 (20%) mice in the LPS group, whereas it was not found in any mice in the Treatment group. Mean TNFalpha and IL-6 levels were statistically higher in the LPS group (394.72+/-403.79; 195.18+/-218.37 pg/ml, respectively) compared to all other groups, including the Treatment group (p<0.05 for each comparison). Within the LPS group of mice, the levels were higher in animals with IN compared to the mice without IN.

CONCLUSION

Increased TNFalpha and IL-6 levels induced by LPS correlated well with the occurrence of IN, and a decrease in these levels via cyclooxygenase (COX) inhibition by indomethacin prevented IN from forming in this experimental model.

Treatment of postoperative enterocutaneous fistulas with octreotide in two neonates

Enterocutaneous fistula (EF) in newborns and prematures is a well-recognized complication after necrotizing enterocolitis and other abdominal surgical procedures. Conservative management consists of bowel rest, antibiotics, wound care, and the administration of drugs that either reduce gastrointestinal motility or secretions. Octreotide decreases gastrointestinal secretions, inhibits or blocks the effects of gastrointestinal hormones, diminishes gut motility and thus reduces the flow through the fistula. We used octreotide and were able to report successful spontaneous closure of a fistula in our 2 neonatal patients, one a premature neonate with necrotizing enterocolitis (NEC) and the other with meconium peritonitis.

Ankyloglossia and effects on breast-feeding, speech problems and mechanical/social issues in children

BACKGROUND

This aim of this study was to define the characteristics of the patients who underwent surgery for ankyloglossia.

PATIENTS AND METHODS

The patients (n = 127) with ankyloglossia underwent surgery between 1987 and 2005. The patients were evaluated for age, gender, complaints, grade, and operative procedures. This study did not cover postoperative evaluation of the procedure.

RESULTS

The ages of the children ranged from 20 days to 7 years, and 84% of them were under 1 year of age. Seventy-two percent were boys; 28% were girls. The most common complaint of the parents of infants under one year of age was breast-feeding (35/84). When the tongue movements of the patients were examined, 57 patients (of whom 18 were over one year of age) had limited tongue mobility. The mean frenulum length of the patients was grade 1 in 72 patients and grade 2 in 55 patients. Ankyloglossia was corrected by frenotomy. Three patients had bleeding from their frenotomy site which resolved with local pressure. General anaesthesia was preferred for 77 patients, and there was a need for suturing in 20 patients.

CONCLUSION

The correction of ankyloglossia at an early age reduces the risk of latent complications. In addition, the early correction will mitigate the feeding- and speech-related concerns of parents and doctors alike.

Surgical breast lesions in adolescent patients and a review of the literature

BACKGROUND/PURPOSE

Breast disease in adolescence is uncommon, with most presenting lesions being benign. Breast lesions in adolescent patients are discussed in this article with a review of world literature.

PATIENTS AND METHODS

The clinical records of 30 patients operated upon for breast lesions in our hospital during 18 years were reviewed.

RESULTS

There were 25 female and five male patients, ranging in age from 16 years. Twenty-five female patients were operated on for breast mass and/or discharge, and five male adolescents were operated on for gynaecomastia. The most frequent (n = 27) complaint was palpation of mass in the breast. The most common histologies were fibro-adenoma (n = 14) and gynaecomastia (n = 5). The average duration of pre-operative symptoms was 2.9 months for fibro-adenoma, 1.6 years for gynaecomastia (extremes 2 days to 1 year). Nipple discharge was observed in three patients. Average diameters of palpable masses were 2.9 cm for fibro-adenomas and 5 cm for gynaecomastia. Lesions were excised surgically in all patients. Masses diagnosed as fibro-adenomas in the pre-operative period were reported upon pathological examination to be precancerous lesions such as cystosarcoma phylloiedes, juvenile fibro-adenoma, solitary intraductal papilloma, tubular adenoma and juvenile papilloma. One postoperative wound infection and one recurrence of fibro-adenoma was seen.

CONCLUSION

The most frequently encountered breast masses were fibro-adenomas. These lesions are mostly benign in nature and can be treated conservatively but the possibility of precancerous lesion should be considered during follow-up.

Unusual localization of hydatid cyst

We report a case of a single large echinococcal cyst that originated from the retroperitoneal space. Diagnosis was confirmed with serologic test and radiological examinations. Especially in the endemic areas hydatid cyst should be considered when evaluating cystic masses and it can be treated by extraperitoneal operation.

Omentum prevents intestinal adhesions to mesh graft in abdominal infections and serosal defects

BACKGROUND

Many studies have evaluated the use of grafts in the reconstruction of abdominal wall defects. In this study, the effects resulting from the presence or absence of the omentum were evaluated in the setting of infection or serosal defects in the formation of adhesions in abdominal closures using mesh grafts.

METHODS

For this study, 60 Wistar albino rats were divided into six groups. A circular 3.79-cm(2) fascioperitoneal defect was created. After group-specific procedures, defects were reconstructed using polypropylene mesh grafts. In group C (control group), only a mesh graft recontruction was performed, whereas group O (O for omentectomy) underwent an omentectomy plus mesh closure. In group SD (serosal defect group), the cecum was abrased with a brush before mesh closure. Group SDO underwent cecal abrasion plus an omentectomy. In group I (infection group), the intraabdominal space was filled with 1 ml of solution containing 100,000 colony-forming units (CFUs) of Escherichia coli per milliliter. Group IO received the same same amount of E. coli solution plus an omentectomy before mesh closure. After 28 days, the groups were evaluated by intraabdominal and blood cultures, grading of intraabdominal adhesions, graft-organ adhesions, proportion of adhesions to graft size, and histopathologic studies. The results were statistically evaluated using one-way variant analysis and Scheffe's and Fisher's definite chi-square tests.

RESULTS

For the groups in which the greater omentum was preserved, intestinal adhesions to the graft surface were less frequently observed, especially in cases with intraabdominal infections and serosal defects (p < 0.05).

CONCLUSIONS

Preservation of the greater omentum reduces the formation of intestinal adhesions, especially in cases with underlying infections and serosal defects in abdominal closures using mesh grafts. This could be beneficial in related clinical situations in lowering the rate of intestinal fistulas, erosions, and obstructions that can be attributed to the formation of adhesions.

Effect of melatonin on healing of colonic anastomosis in a rat model of peritonitis

BACKGROUND

The aim of this study is to determine the effect of melatonin on intestinal anastomosis in the presence of peritonitis.

MATERIAL AND METHODS

32 Wistar albino rats were randomized into four groups (n = 8): A (sham), B (control), C (melatonin 5 mg/kg), and D (melatonin 10 mg/kg). In group A, only cecal dissection was carried out. In the other groups, cecal ligation and puncture (CLP) followed cecal dissection in order to induce bacterial peritonitis. 24 h after the previous operation, cecal resection and ileocolic anastomosis were performed in the rats of all groups. In group C (5 mg/kg) and group D (10 mg/kg), melatonin was injected for 5 consecutive days starting after CLP. At the 48th hour of the CLP procedure, blood was drawn via the tail vein for tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) analysis, and on the 4th day of the experiment relaparotomy was carried out for bursting pressure (BP) measurements. The intestinal tissue containing the anastomotic line was then snap-frozen in liquid nitrogen and stored at -80 degrees C for determination of tissue levels of malondialdehyde (MDA) and glutathione (GSH).

RESULTS

The tissue MDA level, blood TNF-alpha and IL-6 levels of group B were significantly higher than in the other groups, whereas the BP results and GSH levels of group B were found to be significantly lower than in the other groups. The results of groups C and D are statistically different from those of group B. When we compared the results of groups C and D, we found significantly higher results in terms of BP and GSH levels in group D and also significantly lower results in terms of MDA, blood TNF-alpha and IL-6 levels in group D.

CONCLUSION

The findings of this experiment suggest that melatonin has a dose-independent positive effect on wound healing of colonic anastomosis.

Postoperative intussusception in children

Postoperative intussusception (POI) is an uncommon cause of postoperative mechanical bowel obstruction in children. Four cases of POI during a period of 15 years (1987-2001) were analysed retrospectively. Symptoms developed after a median period of 2.5 days following the operation. All cases were succesfully treated with operative manual reduction. POI occurs after a wide variety of surgical procedures and is often difficult to diagnose because the symptoms are often obscure. As a conclusion, we state that reaching a diagnose requires a high index of suspicion.

Effects of amrinone on bilateral renal ischemia/reperfusion injury

Renal ischemia/reperfusion injury could arise as a consequence of clinical conditions such as renal transplantation, shock, cardiac arrest, hemorrhage and renal artery surgery. In this experimental study, we aimed to determine the preventive effects of amrinone on bilateral renal ischemia/reperfusion injury in rats. A total of 60 Wistar-albino rats were divided into six groups ( n=10). Midline laparotomies were made under ketamine anesthesia. In the sham, amrinone1 and amrinone2 without ischemia (AWI1 and AWI2) groups saline, 5 and 10 mg/kg of amrinone was infused, respectively. In the ischemia, ischemia plus amrinone1 (IPA1) and ischemia plus amrinone2 (IPA2) groups, saline and 5 and 10 mg/kg of amrinone was infused, respectively, at the beginning of reperfusion, subsequent to 45 min of bilateral renal artery occlusion. Following 6 h of reperfusion, blood was drawn to study serum BUN and creatinine and a bilateral nephrectomy was done to determine tissue malonyldialdehyde ( MDA) and myeloperoxidase (MPO) levels. The results were analysed by Mann-Whitney U-test. The parameters studied were statistically higher in the ischemia group compared with the other groups ( P<0.05 for each comparison), indicating renal I/R injury. These parameters were lower in the amrinone without ischemia groups (AWI1 and AWI2) than in the sham group, however there were no significant differences between the groups ( P>0.05, for each comparison). The treatment groups IPA1 and IPA2 had statistically similar results compared with the sham group, showing the preventive effect of amrinone on renal I/R injury at the given doses. We conclude that amrinone prevented experimental renal ischemia/reperfusion injury in rats, independently of the administered doses. This preventive effect of the agent could depend on its effect of regulating the microcirculation, in decreasing intracellular calcium and in preventing neutrophil activation. We propose that this preventive effect of amrinone - which has gained clinical application especially in cases of cardiac insufficiency - could also be exploited in clinical conditions related with renal ischemia/reperfusion.

Colon interposition for esophageal stenosis in a patient with epidermolysis bullosa

Epidermolysis bullosa (EB) is a disease with 3 forms, most hereditary, characterized by spontaneous blistering lesions. The autosomally inherited form, epidermolysis bullosa dystrophica recessive (EBDR), is responsible for esophageal lesions consisting of web or stenosis. The authors could find only 9 cases treated by various esophageal replacement procedures in the literature, and the experience with 1 case treated by colon interposition is presented. J Pediatr Surg 36:1861-1863.

Effect of bilirubin in ischemia/reperfusion injury on rat small intestine

PURPOSE

The aim of this study was to determine the effects of bilirubin in experimental small intestinal ischemia/reperfusion (I/R) injury in rats.

METHODS

Thirty rats were divided into 5 groups (n = 6). In group S, saline and in group B, bilirubin, 20 mg/kg were infused via the jugular vein without an additional procedure. In groups S-IR, saline, B(1)-IR and B(2)-IR, 10 and 20 mg/kg/h of bilirubin were infused for 2 hours, respectively. In these groups, an I/R procedure was done after infusions by occluding the superior mesenteric artery for 45 minutes followed by 1 hour of reperfusion. After reperfusion, the small intestines were resected for histopathologic and malondialdehyde (MDA) assessments. Mucosal lesions were scored between 0 and 5. Malondialdehyde levels and histopathologic grades were analyzed statistically.

RESULTS

Mucosal injury was severe in S-IR (grade 4 to 5), mild in B(1)-IR (grade 0 to 3) and none in B(2)-IR group (grade 0). Grades of group S-IR were higher than those of B(1)-IR and B(2)-IR statistically (P <.05). Tissue MDA levels of the S-IR group were significantly higher than those of B(1)-IR and B(2)-IR groups (U = 36, P <.05). Bilirubin levels correlated inversely with MDA levels (r = -0.94).

CONCLUSIONS

Bilirubin effectively prevents intestinal I/R injury in rat. This observation is consistent with the hypotheses regarding bilirubin as an antioxidant, having a role in the body defense. J Pediatr Surg 36:1764-1767.

Postoperative necrotizing enterocolitis following incarcerated inguinal hernia repair: report of a case

The postoperative development of necrotizing enterocolitis (NEC) following major surgery in neonates has often been described. We report herein the case of an older infant in whom postoperative NEC developed following emergency repair of an incarcerated inguinal hernia.

Diffuse fibrous proliferation of tunica vaginalis associated with testicular infarction: a case report

Fibrous pseudotumor of the tunica vaginalis testis is an uncommon lesion of unknown pathogenesis. Although this reactive process of testicular tunics is benign, this usually is diagnosed after radical orchiectomy. The authors describe a case of fibrous pseudotumor of the tunica vaginalis testis associated with testicular infarction. To our knowledge, this is the first case presented with similar association, second case consisting predominantly of myofibroblasts and the fourth reported case encountered in childhood.

Hydatid cysts of the lung in childhood: is capitonnage advantageous?

In the treatment of thoracal hydatid cysts, there is not an agreement whether the cyst cavity to be capitonnaged or not. In this retrospective study, it was aimed to compare the cases of capitonnaged and not capitonnaged thoracal hydatid cysts with regard to hospital stay and post-operative chest tube removal day. Documents of 15 patients operated for pulmonary hydatid cysts in our clinic were reviewed. In 7 cases pericystectomy and removal of germinative membrane was performed whereas in 8 patients capitonnage was added to the procedure. In all cases open airways were suture controlled and pleural cavity was drained with chest tube connected to waterseal system. Average hospital stay of capitonnaged cases was 8 days and of uncapitonnaged ones was 12 days. Thoracal drainage tubes were removed in an average of 4 post-operative days in capitonnaged cases and of 7 days in the others. Statistical analysis were made by Mann-Whitney U test. Difference between the hospital stays of the 2 groups were not significant, whereas it was significant statistically between chest tube removal days (p<0.05). Capitonnage shortens postoperative chest tube drainage period in pulmonary hydatid cysts, resulting in lower morbidity compared with the uncapitonnaged cases.

Comparison of consequent small bowel anastomoses after transient ischemia: an experimental study in rats

BACKGROUND/PURPOSE

The role of ischemia/reperfusion (I/R) damage on intestinal anastomotic healing remains to be precisely determined. The objective of this study was to investigate healing of small bowel anastomoses performed at different times after transient ischemia.

METHODS

Thirty male Wistar-Albino rats were investigated in five groups (four study and one control). Under general anesthesia, the superior mesenteric artery (SMA) was occluded for 40 minutes in the study rats. Biopsy specimens, to document I/R histopathology, were obtained before small intestinal anastomoses at 20 minutes (group 1), 90 minutes (group 2), 6 hours (group 3), and 24 hours (group 4) after reperfusion. In a control group, biopsy and intestinal anastomoses were performed after SMA dissection without occlusion. The rats were relaparotomized on the fifth day to determine in situ bursting pressures and to obtain specimens for hydroxyproline content and histopathologic evaluation.

RESULTS

Hydroxyproline content and bursting pressures were compared statistically with Mann-Whitney U test. Although there was no statistical difference between the control group and group 1, there were significant differences (P < .05) between groups 2, 3, and 4, with both parameters decreasing as the duration after reperfusion increased.

CONCLUSION

Anastomosis are less likely to leak when performed sooner rather than later after an ischemia/reperfusion event.

Assessment of anastomotic reliability with pulse oximetry in graded intestinal ischemia: an experimental study in dogs

BACKGROUND/PURPOSE

Pulse oximetry has been proposed as an appropriate and feasible technique in the assessment of intestinal ischemia in recent years. In this study the authors aimed to assess the reliability of anastomoses in the dog small intestine in which there is graded irreversible ischemia as measured by pulse oxymeter.

METHODS

In a control group of four dogs, without any devascularization, three small bowel anastomoses were formed in each dog. The study group consisted of 12 dogs. In each animal three intestinal segments with different levels of ischemia were created by ligating the marginal vessels proximally and distally in sequence beginning from the midpoint of the segmental vascular arcade. Preanastomotic pulse oximeter readings between 80% and 90% were assigned to mild ischemia, 70% and 80% to moderate, and 60% and 70% to severe ischemia group. Pulse oximetry measurements were obtained from probes applied to the antimesenteric serosal surfaces at the midpoint of small intestinal segments. A total of 48 intestinal segments (12 nonischemic in the control group and 36 with three different levels of ischemia in the study group) were transected in the midpoint and anastomosed in double layers. Postanastomotic SaO2 values were also noted. The anastomoses were evaluated 48 hours later macroscopically if there was any leakage, and biopsy specimens were obtained for histopathologic ischemic gradings. All results were studied statistically.

RESULTS

Histopathologic grades between each group were statistically different (P < .01 for each comparison) except for control and mild ischemia groups (P > .05), worsening as the level of ischemia increased. Pre- and postanastomotic pulse oximetry measurements correlated very well with the histological gradings (r = -0.90, P < .001 and r = -0.93, P < 0.001 respectively). Number of anastomotic leakages were none in control, one in mild, nine in moderate, and 12 (all of the anastomoses) in severe ischemia groups. In the moderate ischemia group with an average preanastomotic pulse reading of 76.75%, each of the leaking anastomoses had a postanastomotic pulse measurement of lower than 70%. The finding that the difference between histopathologic grades of control and mild ischemia groups with average preanastomotic pulse measurements of 96% and 85%, respectively is not statistically significant enables us to suggest that a saturation of at least 85% is necessary for a reliable anastomosis.

CONCLUSION

These results suggest clearly that anastomotic reliability can be predicted objectively with pulse oximetry.

Neovascularization of the testicle through spermatic vessels by omental pedicle flap: a new experimental model

The aim of this experimental study in rats was to consider the supplementary role of an omental pedicle flap on the neovascularization of the testicle through the spermatic vessels, for which a Fowler-Stephens procedure had been planned. To compare results, 12 animals had only the spermatic vessels ligated, without an additional procedure (Fowler-Stephens procedure [FS group]), and 12 others had omentopexy of the spermatic vessels of the left testes, with ligation of the vessels 4 weeks later (Fowler-Stephens procedure plus omentopexy [FSO group]). In the sham group (n = 8), only omentopexy of the left spermatic vessels was performed. Six rats served as controls. In each rat, both testes were evaluated by color Doppler ultrasonography to assess capsular and intratesticular blood flow, followed by orchiectomy to determine testicular weights, testicular biopsy scores, and mean seminiferous tubule diameters. Data were analyzed statistically. According to the color Doppler ultrasonography, the testicular blood flow in the FSO group was better than that of the FS group, but was less sufficient than that of the sham and control groups. The testicular weights and biopsy scores for the FSO group were statistically greater than those of the FS group, and less than those of the sham and control groups. There was no significant difference in the mean seminiferous tubule diameters of the FSO and FS groups. The contralateral tests of the four groups did not differ significantly for any parameter. In light of the data available, it is suggested that the omental pedicle flap neovascularizes the testicle through spermatic vessels. Given the high incidence of testicular atrophy associated with Fowler-Stephens orchiopexies, it might be beneficial to perform laparoscopic orchiopexy of testicles neovascularized with omental pedicle flaps as the first-stage procedure.

Polyorchidism

Polyorchidism, defined as the presence of more than two histologically proven testes, is a rare entity. A review of the literature has yielded 46 cases of true polyorchidism suitable for consideration in this review, and we add two more, one of them being the 12th case of complete duplication of the testis reported in the literature.

Oesophageal rupture due to air-blast injury in children: case report and review of the literature

Perforation of the oesophagus is a surgical emergency that is usually lethal if untreated and commonly fatal if treatment is delayed. The most common type of trauma causing oesophageal perforation is a penetrating injury. Oesophageal ruptures due to external blunt or air-blast injuries are very rare. We report for the first time a case of oesophageal rupture related to air-blast injury to the chest and upper abdomen in a child.
