Chronic right iliac fossa (CRIF) pain in children is associated with repeated hospital attendance, inconclusive investigations, and missed school days. There is increasing evidence for the role of laparoscopic appendectomy for the management of CRIF pain. However, currently there is no substantial evidence to correlate histological changes identified in the appendixes removed with resolution of pain.This study collected prospective data for a single surgeon's series of laparoscopic appendectomy performed for CRIF pain between 2003 and 2014.Forty patients with a median age of 13 years (range 5-19 years) underwent laparoscopic appendectomy for CRIF pain. Twenty-nine patients (73%) had macroscopically normal appendixes, but histological changes were identified in 28 patients (70%). Other findings at laparoscopy included gynecological pathology (ovarian/para-ovarian cysts), unfixed mobile caecum, and a well-defined peritoneal band extending from the caecum to the anterolateral abdominal wall (caeco-peritoneal band). Patients were followed up for a median of 2 months (range 1-15 months). All patients reported resolution of CRIF pain.Laparoscopic appendectomy appears to be an effective treatment for CRIF pain, while also providing the opportunity to diagnose and treat potential sources of CRIF pain other than the appendix. Consistent with the literature, a small number of patients appear to have resolution of pain, despite no histological change being identified in the appendix removed and no other pathology having been identified. The same histological changes commonly seen have also been demonstrated in appendixes removed incidentally. Caution therefore should be applied when interpreting the significance of histological changes seen.

A caeco-peritoneal band (CPB) has been observed during diagnostic laparoscopy for chronic right iliac fossa (RIF) pain. This has a veil-like configuration and arises along a broad base from the caecum and ascending colon and attaches to the anterior abdominal wall.Retrospective analysis of a prospectively collected database of 31 patients, aged 11-16, who underwent diagnostic laparoscopy for ongoing RIF pain over a 10-year period was analysed for intra-operative presence of the CPB. The patients' symptoms, past medical history, diagnostic workup, surgical findings and outcome were evaluated.CPB was identified in five patients. All presented with chronic RIF pain and had inconclusive preoperative investigations. Two patients underwent previous surgery. In all cases, the CPB was the sole abnormal finding on diagnostic laparoscopy. Symptoms resolved following division of the CPB with no recurrence of pain at a mean follow-up of 575 days.CPB is a potential cause of chronic RIF pain in patients with unremarkable examination findings and negative serological and radiological investigations. Laparoscopic identification and division of the CPB has produced symptom resolution in this cohort of patients.

Testicular survival following second-stage Fowler-Stephens (FS) procedure depends upon adequate arterial supply. There is evidence that testicular survival rates are greater following gubernaculum-sparing second-stage FS procedure. The importance of collateral vessels in preservation of the testis has been hypothesised, but never shown in the literature. We aim to map the collateral blood supply to the testicle in gubernaculum-sparing, laparoscopic-assisted, second-stage FS procedure for intra-abdominal testicles.Selected patients undergoing a second-stage FS procedure were photographed prior to pexy in the Dartos pouch. Photographs were evaluated for the extent of vascular collateralisation between gubernacular, deferential and the ligated spermatic artery.Twenty-five patients with 28 undescended testicles underwent staged FS procedure over a 7.5-year period between 2005 and April 2013. Mean age at operation was 2.44 years, and all testicles were delivered to the scrotum. Mean follow-up was 3.29 years, and all patients were reviewed by the operating consultant. Testicular survival rate was 100 %. Representative photographs clearly demonstrate substantial cremasteric vessels running along the gubernaculum with robust collateralisation to the deferential vessel and the spermatic arterial stump.These images confirm the presence of robust collateral between the cremasteric and deferential vessels at second-stage FS procedure. Preservation of these collaterals in a gubernaculum-sparing approach may explain the excellent results seen in this series.

Congenital H-type fistulae are a rare abnormality. They commonly present with only minor respiratory complications and can, therefore, be difficult to identify. Conventionally, correction is via a ligation performed via either a cervical or thoracotomy incision, dependant on the fistula site. Thoracoscopic repair is emerging as a tenable alternative to traditional approaches and offers some advantages. This paper details the technical aspects of the thoracoscopic ligation of an H-type fistula.

A single surgeon's 5-year experience of preserving the gubernaculum in laparoscopic-assisted Fowler-Stephens orchidopexy is reported. Thirty-six cases of impalpable testes are considered. Sixteen patients were confirmed as having intra-abdominal testes, with 20 testes considered to be absent/vanished. At follow-up, all testes had a similar volume to the contralateral testis except for one that had been considered hypoplastic at the initial operation. Mean follow-up was 612 days. The method and potential importance of gubernacular preservation in this situation are discussed.

In recent years, laparoscopic equipment, and experience with its use, has improved. We are now able to appreciate microanatomy, and dissection of individual lymphatic channels is possible. Previously, the results of laparoscopic lymphatic-sparing procedures has been reported. In this study, we report our experience of the preservation of both the lymphatic channels and the testicular artery during laparoscopic varicocelectomy and its outcomes.All boys undergoing laparoscopic varicocelectomy between June 2004 and February 2009 were included in the study. The demographic details, operative findings, complications, and length of stay were recorded on a Microsoft Excel spreadsheet and complications at follow-up noted. The operation was performed via a transperitoneal approach, and the retroperitoneum was entered proximal to the internal ring by peritoneal division over the vessels. The spermatic vein or veins were isolated and stripped of the surrounding lymphatics and artery and secured with ligaclips. Any other tortuous veins around the internal ring were also ligated at the time of operation.Nineteen boys underwent laparoscopic varicolectomy. Complications were 1 intraoperative small bowel injury, 1 hydrocele (5%), and 4 persistent varices (21%), one of which was symptomatic, requiring a low ligation of spermatic veins through a groin approach.This study shows good results with regard to postoperative hydrocoele rates. The preservation of the lymphatic supply ensures adequate lymphatic drainage, therefore, minimizing the risk of developing a hydrocele postoperatively. The risk of persistent varices, compared to the traditional en-masse technique, is a source of concern and requires further study.

The value of laparoscopy in repair of congenital duodenal webs is yet to be established and techniques are evolving. Described are technical details of a successful laparoscopic web ablation without duodenoplasty.

This article highlights the difficulties posed by initial radiological investigations that misleadingly interpreted a linear opacity in the ascending colon of a 2-year-old to be a complicating calcified Ascaris. Final surgical management revealed an unusual cause for the tram tracking effect so pathognomonic of Ascaris infestation. Of interest are the images of the abdominal x-ray, ultrasound scan, and barium study.

We read with interest the article by Choi et al. However, the incidence of bilateral inguinal hernias/patent processus vaginalis (PPV) (infants—61 %, older children—35 %) seen at laparoscopy is significantly higher than other published studies and our own experience. Our 2011 systematic review of 61 studies of pediatric inguinal hernia repairs, published in this journal, identified 2,857 patients from a total of 49,568 who developed a metachronous contralateral hernia after their initial unilateral repair [1]. The incidence of bilateral inguinal hernias in children under 6 months of age was just 12.4 % with an overall incidence of 5.6 %. In the light of these discrepancies, the clinical significance of many inguinal canal defects seen at laparoscopy must be low. As there are risks involved in laparoscopic hernia repairs, especially to the testis in males, it seems sensible that the criteria for correction of sub-clinical contralateral abnormalities should be re-defined to enable convergence of these widely disparate figures.

Circumcisions are among the most frequently performed operations in children and numerous techniques are employed often with varying results. Use of the Plastibell™ (Hollister Incorporated, Illinois, USA), under local anesthetic, is popular for cultural and religious circumcisions but is not without its problems. Complications of Plastibell™ (slippage, migration, bleeding and serious infection) have been reported. Described is a prospective series of cases in which modifications to the standard Plastibell™ technique were utilized to improve outcomes, in particular, the risk of bleeding.

Laparoscopic management of congenital ovarian cysts is widely practiced but there is a dearth of information on the performance of the gonad where organ-preserving surgery is undertaken. Presented is a radiological diary documenting the progress of a complex congenital ovarian cyst from the antenatal period to a year post-laparoscopic decapsulation.

To assess the performance of a paediatric cohort having a FRECA PEG (FP) placed at the time of laparoscopic fundoplication.This is retrospective study of a single surgeon's experience of laparoscopic fundoplications over a decade. Patient details were retrieved form a Microsoft Excel database and demographic, operative, and performance measures analysed.Of a series of 67 laparoscopic fundoplications, 20 with neurological compromise underwent FP placement at the time of surgery. Mean age was 3.37 years with a male to female ratio of 1.1:1. A size 9 French FRECA was placed in patients less than 10 kg (12) with larger patients (8) having a size 15 device. A Watson anterior wrap was performed in 16 cases with the rest having a Nissen fundoplication. Seven of these cases had pre-existing FPs which were taken down before replacement post fundoplication. Feeding was resumed the next morning except in three with delayed gastric emptying. Other complications (3) were seen but were not PEG related. The median stay for the series was 4 days (SD 3) and patients were followed up for a mean of 684 days. Over this period four patients relapsed and resumed medical treatment. A single mortality occurred in a syndromic 3-year-old a year later from problems unrelated to surgery. FPs were changed to a button device under general anaesthetic 3-24 months following placement.FP placement at the time of laparoscopic fundoplication does not appear to compromise the outcome of surgery. Neither the size of patient nor the type of wrap is an impediment to its placement and the device can be used shortly after surgery in the majority allowing for an early discharge. Complications are infrequent; however, change to a button device within 2 years of initial placement requires general anaesthetic.

Laparoscopic cholecystectomy is the treatment of choice in symptomatic paediatric cholelithiasis. However, controversy exists about its role in asymptomatic cholelithiasis and biliary dyskinesia. We have reviewed the experiences of two UK paediatric centres with laparoscopic cholecystectomy over an 8.5 year period and critically evaluated the indications and outcomes of surgery.Patients who underwent laparoscopic cholecystectomy by a single surgeon at the Royal Aberdeen and Royal Alexandra Hospitals between May 1996 to August 2003 and September 2003 to December 2005, respectively, were studied. Information was extracted from prospectively held databases and analysed.A total of 27 cholecystectomies were performed during the period of study. The mean age of patients was 11.7 years with a female preponderance. Symptomatic idiopathic cholelithiasis was the main indication for surgery (14). Cholecystectomy was also performed for haemolytic disease (3), acute recurrent pancreatitis of unknown cause (2), gallbladder trauma (1), and for asymptomatic calcific non-resolving stones (7). All patients were investigated with ultrasound scans with four patients undergoing magnetic resonance cholangiopancreatography (MRCP) for suspected common bile duct (CBD) stones. A standard four-port approach was used with the gallbladder extracted through the umbilical port. The mean operative time in the latter 13 cases was 105 minutes with a median postoperative stay of one day for the whole series. Histology revealed chronic cholecystitis in all but three cases. All patients were discharged after a six-month follow-up period.The advent of laparoscopy has resulted in an expansion of the traditional indications for cholecystectomy. MRCP is a useful investigation in selected children to exclude choledocholithiasis and avoid intraoperative cholangiography. There appears to be no clear correlation between histology and presenting symptoms. The natural history of asymptomatic gallstones in children is not known although a consensus is emerging to support cholecystectomy for all calcific non-resolving gallstones.

The aims of this study was to determine whether an active policy of cost curtailment would impact on the theater cost of laparoscopic surgery in a pediatric setting; to document the extent of cost changes over time and to identify factors that adversely influence expenditure; and to investigate whether the surgeon is a significant factor in the price of the procedure.A prospective audit of laparoscopic procedures was performed in a single unit over a 36-month period. Detailed costs of theater inventory for all procedures were compiled on a case-by-case basis and recorded on a database. The cost of six index procedures were collated and changes over the period of the study analyzed. The factors responsible for increased expenditure were flagged and appraised to enable the implementation of cost-saving measures. The prices of the laparoscopic equipment were based on invoiced figures provided by hospital managers, and no long-term outcome measures were taken into account.A total of 179 cases were performed by six surgeons over a 3-year period between January 1, 2003 and December 31, 2005, with no adverse intraoperative events. The procedures studied in further detail were appendicectomy (n = 50), fundoplication (n = 25), cholecystectomy (n = 12), nephrectomy (n = 10), Fowler Stevens for undescended testes (n = 10), and modified Palomo operations for varicocoele (n = 7). The mean cost of these procedures fell year by year over the period of study but was significant only in appendicectomy (P = 0.017). For this procedure, there was a significant difference in costs between the various surgeons (P = 0.007), but this trend was not noted with the other procedures. There were no major intraoperative events, although 2 patients required conversion owing to technical difficulties posed by the cases. Among the factors that influenced costs were the use of disposables, particularly for hemostasis and suctioning, and an inability to procure reuseable instruments.The costs of commonly performed laparoscopic procedures are falling year by year. The surgeon is a factor in the costs of some procedures. A cost-saving strategy has not been compromised of patient safety; however, some cost-saving measures, though attractive, are labor intensive and are not practical. An overall commitment to the sensible use of health care resources translates into savings for hospitals, thereby strengthening the case for laparoscopic surgery.

Objective: The aim of this paper is to demonstrate that laparoscopy can successfully diagnose otherwise elusive Meckel's diverticuli and at the same time offer a therapeutic access for successful resection. Materials and Methods: Two patients with anemia of unknown cause and a further patient with acute small bowel obstruction underwent diagnostic laparoscopy. A Meckel's diverticulum was identified in each case and successfully resected through a minilaparotomy. Results: All three patients were successfully investigated and treated with laparoscopy with no morbidity or mortality. Conclusion: Laparoscopy is a safe and effective surgical modality for diagnosis of atypically presenting Meckel's diverticulum and has a therapeutic role that results in an excellent cosmetic result.

To determine whether elective laparoscopic appendicectomy is justified for chronic right iliac fossa (RIF) pain of undetermined origin.A retrospective audit of all laparoscopic appendicectomies between January 1997 and August 2003 was performed. The expanded medical audit system (EMAS) and a Microsoft Access database of operative records were used to identify patients with chronic RIF pain subjected to elective appendicectomy. Case notes were retrieved and analysed for patient profile, duration of symptoms including clinic visits and admissions, operative findings, histological analysis, and postoperative performance. A correlation between histological findings and final outcome was investigated.Ninety-eight patients underwent laparoscopic appendicectomy during the period of the study. A total of 11 cases with chronic RIF pain were identified. Nine were female and 2 male. Age ranged from 9 to 14 years with a mean of 11.9 years. The number of clinic visits and admissions for chronic RIF pain ranged from 2 to 8, with a mean of 4. Duration of symptoms ranged from 1 to 36 months, with a mean of 12.1 months. Detailed history, clinical examination, and serological and radiological investigations failed to reveal the cause of the pain in all cases. Patients were followed up in postoperative clinics for between 1 and 72 months, with a mean of 16.1 months. Histology of resected appendices showed acute inflammation (3 cases), fecoliths (2 cases), lymphoid hyperplasia (LH) (1 case), LH and a foreign body reaction (1 case), LH and mucosal hyperplasia (1 case), and Enterobius vermicularis parasites in 1 case. The appendix was normal in 2 cases. Eight patients had complete resolution of RIP pain. Seven of these had pathology within the appendix and 1 was histologically normal. Two patients with resolved RIF pain, but with pain elsewhere, had lymphoid hyperplasia noted within the appendix. One patient with persistent pain 6 years postoperatively had a normal appendix.This study demonstrates that a significant number of patients with chronic RIF pain have pathology within the appendix. The majority of these cases will benefit from elective appendicectomy. It is critical however that all other possible causes of pain in the RIF are excluded. Laparoscopy is an integral part of the diagnosis and management of this particularly difficult group of patients.

Laparoscopic transperitoneal nephrectomy is technically feasible in most cases of benign renal disease. To date, there have been isolated reports of laparoscopic transperitoneal heminephroureterectomy of principally the upper moiety of a duplex system. Rarely reported are lower moiety nephroureterectomies.The aim of this IPEG submission is to present a 3-minute video demonstrating the technical details of a transperitoneal laparoscopic, right, lower moiety, heminephroureterectomy in a 3-year-old. METHODS/TECHNIQUES: A child with marginally functioning (5%) lower moiety of a right duplex system was subjected to a transperitoneal heminephroureterectomy. The patient was placed in a left lateral position and an umbilical camera and two working ports (right iliac fossa, epigastric), all 5 mm, were utilized. The ascending colon was reflected to the left and the underlying lower moiety ureter identified and isolated. With traction on the ureter, the pelvis was brought into view and control of blood supply to the lower moiety was achieved by using a combination of ultrasonic scalpel and hook diathermy. A critical step at this stage was definition of the superior limit of the pelvis, which corresponded to the level of vascular demarcation. The renal parenchyma was transected at this point by using the ultrasonic scalpel, which ensured reasonable hemostasis. Complete hemostasis was assured by approximating the divided kidney with a series of three interrupted intracorporeal sutures. The subtending ureter was dissected close to the bladder base, where it was ligated and divided. A drain was placed percutaneously in the renal bed and the specimen retrieved via an extended umbilical incision.The patient was started on fluids on recovery with oral feeds introduced the next morning. The drain was removed prior to discharge on day 2. At 6 months post-resection, the patient remains well.Laparoscopic transperitoneal lower pole heminephroureterectomy is technically feasible for benign renal disease in children. The combination of ultrasonic scalpel and intracorporeal suturing is adequate to control bleeding of the transected kidney. Dissection of the ureter distally to bladder neck is easily achieved without change in port position. Recovery is robust with minimal requirement for analgesia. The wider space, better view, and ability to access all of the urinary tract make this a tenable alternative to other laparoscopic approaches.

A best evidence topic was constructed according to a structured protocol. The question addressed was: In children undergoing umbilical hernia repair is a rectus sheath block (RSB) better than local anaesthetic infiltration of the surgical site, at reducing post-operative pain? From a total of 34 papers, three studies provided the best available evidence on this topic. One randomised clinical trial showed RSB had a better analgesic effect in the immediate post-operative period. In another randomised trial opioid consumption in the peri-operative period was found to be significantly lower in patients administered RSB. These improvements in pain and analgesia consumption need to be balanced against the expertise, training, equipment required, time implications and complications of performing a RSB.
