Aim: To compare tunica vaginalis with dartos flap as soft tissue cover in primary hypospadias repair. Materials and Methods: 25 cases (age range: 12-132 months; all fresh cases) of primary hypospadias were prospectively repaired by tubularized incised plate (TIP)/TIP + graft urethroplasty using tunica vaginalis flap (TVF) as soft tissue cover to urethroplasty (group A). Their results were compared with another set (group B) of age- and anatomy-matched controls (25 patients operated during the previous 3 years) who had undergone TIP repair using dartos flap as soft tissue cover. Statistical analysis of results was done with Fischers exact test. Results: Group A: No fistula, skin necrosis, meatal stenosis, urethral stricture. One case had partial wound dehiscence that resolved on conservative treatment with no sequelae. One case required catheter removal on 3rd day because of severe bladder spasm. There was no testicular atrophy/ascent. Group B: 3 fistulae – all required surgery. There were three cases of superficial skin necrosis that healed spontaneously without sequel. There was no meatal stenosis/urethral stricture. The difference in fistula rate between both the groups, however, was not statistically significant (P = 0.4). Conclusion: TVF may have an edge over dartos fascia for soft tissue coverage of the neourethra.

PURPOSE To test the hypothesis that during laparoscopic hernia repair, partial resection of the distal sac along with suture ligation of the neck is better than simple transection and ligation. METHODS The following two techniques of laparoscopic hernia repair were compared: Group I, circumferential incision of peritoneum at the deep ring and partial resection of the distal sac and suture ligation at the neck; versus Group II, circumferential incision of the peritoneum at the deep ring and suture ligation at the neck. Twenty-five cases of inguinal hernia were randomly selected in each group between the age group of 6 months to 12 years. The outcome measures were recurrence, intra- or postoperative complications, and time taken for surgery. RESULTS There were no recurrences in either group. Other parameters for comparison were also not statistically different between the two groups. There was no conversion. CONCLUSIONS Although partial resection of the sac has been an essential step in open hernia repair over five decades, its value has been questioned by our study, because omitting this step during laparoscopic repair has not adversely affected the outcomes. Partial resection of the sac is not a necessary component of hernia repair. It is a technical necessity of the open approach. Therefore, omitting this step in laparoscopic repair does not adversely affect the outcome.

Laparoscopic repair of hernia in children: Comparison between ligation and nonligation of sac

Nitin Pant; Satish Kumar Aggarwal; Simmi K Ratan

Aim: The essence of the current techniques of laparoscopic hernia repair in children is suture ligation of the neck of the hernia sac at the deep ring with or without its transection. Some studies show that during open hernia repair, after transection at the neck it can be left unsutured without any consequence. This study was aimed to see if the same holds true for laparoscopic hernia repair. Materials and Methods: Sixty patients (52 boys and eight girls, 12-144 months) with indirect inguinal hernia were randomized for laparoscopic repair either by transection of the sac alone (Group I) or transection plus suture ligation of sac at the neck (Group II). Outcome was assessed in terms of time taken for surgery, recurrence, and other complications. Result: Thirty-eight hernia units in 28 patients were repaired by transection alone (Group I) and 34 hernia units in 29 patients were repaired by transection and suture ligation (Group II). Three patients were found to have no hernia on laparoscopy. Recurrence rate and other complications were not significantly different in the two groups. All recurrences occurred in hernias with ring size more than 10 mm. Conclusion: Laparoscopic repair of hernia by circumferential incision of the peritoneum at the deep ring is as effective as incision plus ligation of the sac.

Laparoscopic-assisted transanal pull-through for Hirschsprung's disease: Comparison between partial and near total laparoscopic mobilization of rectum.

Mohit Kumar Mathur; Satish Kumar Aggarwal; Simmi K Ratan; Shandip Kumar Sinha

Background: Transanal pull-through with laparoscopic assistance is gaining popularity. How much rectal dissection to do laparoscopically and how much transanally is not clear. Laparoscopic rectal mobilization is akin to open pelvic dissection of Swensons operation — the most physiological procedure. Through this comparative study, we aim to evolve a technique that maximizes the benefits of Swensons technique and minimizes the problems of a transanal procedure. Materials and Methods: Twenty patients (19 boys and one girl, newborn to 6 years) with Hirschsprungs disease (HD) were randomized for laparoscopic-assisted transanal pull-through (LATAPT) either by near complete (Group A) or partial (Group B) laparoscopic mobilization of rectum. Patients were followed up for at least 3 months. Demographic profile; operative details (time taken, blood loss, operative difficulty, and complications); postoperative course (duration of urinary catheter, oral feeding, and hospital stay); and follow-up stooling pattern, consistency, and continence were compared in the two groups. Results: The time taken for laparoscopic mobilization was marginally higher in group A, but the time taken for transanal dissection in this group was significantly less than in group B. All other comparisons showed no significant difference in the two groups. Stool frequency and continence improved with time in both groups. Conclusion: Extent of laparoscopic mobilization of rectum does not appear to be a factor deciding the outcomes. No recommendations could be made in view of the small number of cases. However, it shows that laparoscopic assistance can be used to maximize the benefits of Swenson type of operation and a transanal pull-through.

Background: To evaluate if hormonal profile of children with isolated hypospadias (IH) associates better with comprehensive local anatomical factor score (LAFS) than with clinically adjudged urethral meatus location or severity of chordee/k.j. Material and Methods: Ninety-nine children with IH were enrolled, as per inclusion criteria. Meatal location was recorded at first clinical examination in OPD; while LAFS was computed per-operatively using indigenously devised scale, except for neonates. Hypospadiacs were first classified into three standard meatal based groups and subsequently into LAFS based two groups (≤19, >19). For all participants, pre HCG and post HCG (96 hour post- injection) estimation of serum gonadotropins, DHEA-S, estrogen (E), progesterone (P), testosterone (T) and Dihydrotestosterone (DHT) was done. Statistical tests were applied to assess significance of hormonal levels with respect to meatal location, chordee and LAFS. Results: Only FSH levels differed significantly among meatal based groups; while among LAFS groups, multiple hormonal differences were noted; with poor LAFS associated significantly with higher FSH, LH and lower E, T/DHT. Children with severe degree of chordee had poorer T output and a significantly lower LAFS as compared to those with moderate/mild chordee. Conclusion: Serotoli cell dysfunction, indirectly indicated by high FSH was found among midpenile hypospadiacs and those with poorer LAFS. Since groups based on LAFS revealed multiple intergroup hormonal differences than what was seen for meatal/chordee based groups; LAFS should be considered a better guide for prognostication and for deciding about hormonal supplementation. Lower androgenic output was particularly noted in children with severe chordee.

OBJECTIVE The objective of this study was to review our experience of laparoscopic (LA) or laparoscopic-assisted pelvic surgery (LAPS) in small infants. MATERIALS AND METHODS The medical records of 35 patients who underwent an LA or LAPS between January 2007 and June 2010 were studied and 21 patients who were younger than 1 year or whose weight was less than 10  kg were included. Indications, procedures, results, and complications were analyzed. RESULTS The indications of surgery and procedures done were impalpable undescended testes (7 cases--3 single-stage orchidopexy and 4 Fowler Stephen stage I ligation of testicular vessels), Hirschsprungs disease (HD; 5 cases--all laparoscopic-assisted transanal pull-through), anorectal malformation (ARM; 3 cases--all laparoscopic-assisted pull-through), disorders of sexual differentiation (3 cases--1 herniotomy and 2 gonadal biopsy), sacrococcygeal teratoma (1 case--laparoscopic mobilization of pelvic component and posterior sagittal excision), and ovarian mass (2 cases; laparoscopic oophorectomy). There were 14 males, 4 females, and 3 of indeterminate sex. All procedures could be successfully completed without conversion. There was no anesthesia-related complication or need for postoperative ventilatory support. There were no immediate procedure-related complications. One female child with ARM had rectal mucosal prolapse; 1 HD case had rectovaginal fistula that healed following fecal diversion. The major advantages of laparoscopy in different indications were magnified access into the depth of pelvis and early frozen section biopsies in HD, accurate placement of neoanus in the center of muscle complex in ARM, early ligation of vessels and avoidance of laparotomy in sacrococcygeal teratoma, ease of decision making and better mobilization of vessels in undescended testes, and diagnostic accuracy and therapeutic procedure in ambiguous genitalia. CONCLUSION Laparoscopic pelvic surgery in small infants is a safe procedure with advantage of magnification, access, and cosmesis.

Association of levels of serum inhibin b and follicle-stimulating hormone with testicular vascularity, volume, and echotexture in children with undescended testes

Abhishek Chinya; Simmi K Ratan; Satish Kumar Aggarwal; Anju Garg; Tarun Kumar Mishra

Aims: The aim of our study was to assess the association between reproductive hormones (inhibin B [inh B], follicle-stimulating hormone [FSH]) with testicular volume, echogenicity, and blood flow (resistive index [RI]) in children with undescended testis (UDT). Settings and Design: This was a prospective study of 1-year study duration. Materials and Methods: A total of 33 patients (16 unilateral and 17 bilateral) UDTs aged 5-12 years with palpable UDT were included in the study. Morning fasting blood samples were taken for estimation of serum inh B and FSH as well as inh B/FSH ratio. Testicular ultrasound was done to compute testicular volume, testicular echogenicity, and testicular vascularity in terms of RI. Results: The mean age of patients enrolled in the study was 8.29 years for unilateral UDT and 7.97 years in bilateral UDT and it was comparable. The study groups were further subdivided into two age-wise subgroups school goers (5-8 years) and prepubertal (9-12 years). The values of inh B, FSH, and inh B/FSH ratios as well as mean testicular volume were comparable between both groups and subgroups. Overall mean testicular volume had a positive correlation with FSH, inh B, and inh B/FSH, but statistical significance was reached only for inh B (P < 0.001) in children with both unilateral and bilateral UDT. Apart from five patients with hypoechogenicity within the testis, all remaining testes were of homogenous echotexture with no instances of irregular echogenicity or tumor. Children with RI >0.6 were separately studied. The incidence of high RI (>0.6) was also comparable in unilateral or bilateral disease. These subjects had unfavorable biochemical parameters in terms of low inh B levels and high FSH levels. Conclusions: Our findings hint to the fact that palpable UDT forms a homogenous group, whether unilateral or bilateral, whereas impalpable testes may form a separate category and need further studies to substantiate this hypothesis.

Perforated duodenal ulcer: A rare cause of acute abdomen in children

Rajpal Singh Sisodiya; Simmi K Ratan; Balkrishna Tripathi

Duodenal ulcer perforation is uncommon in children which is why it is not usually considered in the differential diagnosis of acute abdomen in them. In this brief report, we are presenting a case of successfully managed perforated duodenal ulcer in a child. Another interesting point was the presence of air only under right hemidiaphragm, a sign generally known to be associated with duodenal perforation.
