    ABSTRACT: In recent years, the use of robotic-assisted surgery (RAS) has expanded within pediatric surgery. Although increasing numbers of pediatric RAS case-series have been published, the level of evidence remains unclear, with authors mainly focusing on the comparison with open surgery rather than the corresponding laparoscopic approach. The aim of this study was to critically appraise the published literature comparing pediatric RAS with conventional minimally invasive surgery (MIS) in order to evaluate the current best level of evidence. A systematic literature-based search for studies comparing pediatric RAS with corresponding MIS procedures was performed using multiple electronic databases and sources. The level of evidence was determined using the Oxford Centre for Evidence-based Medicine (OCEBM) criteria. A total of 20 studies met defined inclusion criteria, reporting on five different procedures: fundoplication (n=8), pyeloplasty (n=8), nephrectomy (n=2), gastric banding (n=1), and sleeve gastrectomy (n=1). Included publications comprised 5 systematic reviews and 15 cohort/case-control studies (OCEBM Level 3 and 4, respectively). No studies of OCEBM Level 1 or 2 were identified. Limited evidence indicated reduced operative time (pyeloplasty) and shorter hospital stay (fundoplication) for pediatric RAS, whereas disadvantages were longer operative time (fundoplication, nephrectomy, gastric banding, and sleeve gastrectomy) and higher total costs (fundoplication and sleeve gastrectomy). There were no differences reported for complications, success rates, or short-term outcomes between pediatric RAS and conventional MIS in these procedures. Inconsistency was found in study design and follow-up with large clinical heterogeneity. The best available evidence for pediatric RAS is currently OCEBM Level 3, relating only to fundoplication and pyeloplasty. Therefore, higher-quality studies and comparative data for other RAS procedures in pediatric surgery are required.

    ABSTRACT: This study presents a technical report of a standardized approach to the perinephric area in a series of pediatric patients, demonstrating that whatever renal or suprarenal surgery is planned, this can be approached and accomplished laparoscopically with an identical or very similar port triangulation, thus facilitating the learning curve within the same surgical team. All patients undergoing renal and adrenal gland surgery with a minimally invasive approach in the period from October 2008 to November 2013 were retrospectively reviewed and included in the study. Technical details and clinical outcomes are described. In total, 68 patients matched the inclusion criteria and were therefore retrospectively examined. No major intraoperative complication occurred. Two patients developed recurrent pelvic-ureteric junction obstruction and were managed with double J stent positioning and laparoscopic dismembered pyeloplasty, respectively. Two patients presenting with adrenal mass experienced a moderate bleeding that could be treated conservatively. Thanks to the reproducibility of the procedure and on the grounds of the presented experience, we support the proposal that the transperitoneal laparoscopic approach to the kidney and the adrenal gland could represent a relatively easy and safe way to quickly achieve confidence and skill in the management of related diseases.

    ABSTRACT: Intussusception is the most common cause of bowel obstruction in children from 3 months to 3 years of age. In the absence of peritonitis, initial treatment is either hydrostatic or pneumatic reduction. If these measures fail, operative intervention is required. In nonreducible cases, we propose the use of intraoperative hydrostatic enema to achieve or confirm reduction. In this study we describe a cohort of patients who have undergone laparoscopic-assisted hydrostatic reduction of intussusception (LAHRI). This is a retrospective cohort study of all patients undergoing LAHRI from the years 2011 to 2013. We performed LAHRI in seven children 4 months to 2 years of age. All patients had ileocolic intussusception that failed initial reduction by radiographic enema. With the patient under general anesthesia, saline enema reduction was facilitated by direct laparoscopic visualization. In 2 of the 7 cases, intussusception reduction was visually confirmed in real time, and only a laparoscopic camera port was required. In 1 patient, the bowel was extensively dilated, requiring mini-laparotomy for visualization. The enema, however, reduced the intussusception without any need for manual reduction. In the remaining 4 cases, minimal laparoscopic manipulation was required after the enema failed to completely reduce the intussusceptum, but enema was used to confirm reduction. No child required bowel resection. In cases of failed reduction by contrast enema, we have demonstrated LAHRI to be a successful treatment modality. The technique has the advantage of little to no bowel manipulation and has evolved into one performed via a single umbilical port.

    ABSTRACT: Good indications for laparoscopic hepatectomy are still considered to be tumors located over anterolateral segments of the liver. Tumors located over the right posterior section are considered to be difficult for laparoscopic resection. In this case series, we present our experience on laparoscopic right posterior sectionectomy. All patient data were prospectively collected. Data on patient demographics, tumor characteristics, operative data, and postoperative outcome were collected and analyzed. During the period of May 2010-May 2014, we performed 13 laparoscopic right posterior sectionectomies. The diagnoses were hepatocellular carcinoma in 11 patients, of which 2 were cases of colorectal liver metastasis. Median operative time was 381 minutes, and median blood loss was 1500 mL. Significant bleeding occurred in the first 5 patients. The median size of the tumor resected was 3.7 cm, and the median resection margin was 8.7 mm. Four of the 13 patients (30.8%) were cirrhotic on histological examination. There was no postoperative mortality. Median hospital stay was 7 days. Laparoscopic right posterior sectionectomy is technically demanding. A proper inflow and outflow control is mandatory for proper anatomical resection. This surgical principle should not be compromised in the era of laparoscopic hepatectomy.

    ABSTRACT: Omohyoid muscle syndrome (OMS) (not omohyoid syndrome) is a rare clinical condition that has a characteristic feature of a protruding lateral neck mass during swallowing. The use of endoscopic surgery on the neck is now pretty well established for thyroid and parathyroid glands. Patients with OMS usually undergo simple surgical transection of the omohyoid muscle. The procedure leaves operative scars on the neck, and most patients worry about the cosmetic problems. We report here the first use of an endoscopic procedure instead of traditional surgery for treatment of OMS. We present a rare case of a 26-year-old Chinese man who noted a protruding mass involving the right side of his neck during the past 10 years. OMS was diagnosed. Laparoscopic simple transection of the omohyoid muscle by an ultrasonically activated scalpel was performed. After laparoscopic transection of the omohyoid muscle, the neck mass completely disappeared during swallowing, and there were no operative scars on the neck. To our knowledge, this is the first report of laparoscopy for treatment of OMS. We believe that the laparoscopic procedure is made acceptable for this unusual disease because of the cosmetic result.

    ABSTRACT: To report a laparoscopic approach for pediatric inguinal hernia repair using a hybrid single-incision laparoscopic (H-SIL) technique and its clinical outcomes. A retrospective study was carried out in inguinal hernia cases treated with the new H-SIL approach using intracorporeal jumping purse-string sutures. The operative time, length of postoperative hospital stay, efficiency of the operation, and complications were analyzed. In total, 157 inguinal high ligations were performed in 106 children (89 boys, 17 girls). The median age was 1.5 years (range, 25 days-11.6 years). The mean operative time was 15.8±3.4 minutes for the single-side procedure and 20.3±2.5 minutes for bilateral procedures. The mean postoperative hospital stay was 0.99±0.52 (range, 0.25-3 days). No postoperative bleeding, abdominal wall emphysema, abdominal viscera injury, or scrotal edema was found, and there were no known cases of postoperative testicular atrophy or hypotrophy. Ninety-three percent of the patients became fully mobile on the first postsurgical day. The median follow-up period was 17 months (range, 9-21 months), with no recurrence, no visible scars on the abdominal wall, and no foreign body felt in the inguinal region. This H-SIL approach is a safe and efficient method for pediatric inguinal hernia repair. The maneuverability is the same as that in the triport laparoscopic technique, and the cosmetic results are similar to those of single-port laparoscopic surgery.

    ABSTRACT: A novel technique using a single-incision laparoscopic approach has been described for several laparoscopic procedures. The aim of this article is to describe our experience with an alternative technique for laparoscopic distal pancreatectomies using a single-port platform. We have performed this procedure on 20 patients with pancreatic tumors in the pancreatic body or tail. A transumbilical incision is performed, and a single-incision platform is introduced. The stomach is sutured to the abdominal wall to expose the pancreas. This technique uses an additional 5-mm trocar in the left quadrant, ultimately used for drainage after the end of the procedure. The median operative time was 176 minutes, and the hospital stay was 2 days. Mortality was 0%, and morbidity was 20%; 4 patients developed grade A pancreatic fistula. During follow-up (median, 11 months), no patient developed an incisional hernia. The cosmetic appearance of the incision was excellent in all cases. Laparoscopic distal pancreatectomy using a single-port platform is feasible and can be successfully performed by surgeons with experience in pancreatic and advanced laparoscopic surgery.

    ABSTRACT: Natural orifice translumenal endoscopic surgery (NOTES(®); American Society for Gastrointestinal Endoscopy [Oak Brook, IL] and Society of American Gastrointestinal and Endoscopic Surgeons [Los Angeles, CA]) is an improvement in surgical interventions. In this study we developed an innovative transtracheal endoscopic thyroidectomy technique and explored its feasibility in animal models. Transtracheal endoscopic thyroidectomy was performed in anesthetized dogs and pigs. The endoscope was advanced into the pretracheal space via a longitudinal incision on the anterior tracheal wall. Hemithyroidectomies and partial lobectomy were performed using special double-lumen endotracheal tubes and conventional endoscopic instruments. The tracheal wall incision was closed using absorbable sutures, and the animals were sacrificed at Day 5 postsurgery. Hemithyroidectomy and partial thyroidectomy were successfully performed on pigs and dogs. The average operative time for each model was 69.4 minutes. No significant complications were encountered during surgery. The transtracheal endoscopic thyroidectomy technique is feasible and has the potential to be an alternative method for other types of thyroid surgeries.

    ABSTRACT: To compare surgical outcomes of two procedures for laparoendoscopic single-site (LESS) hysterectomy: total laparoscopic hysterectomy (TLH) and laparoscopically assisted vaginal hysterectomy (LAVH). Seventy-six patients who had an indication for hysterectomy for benign uterine disease were randomized to LESS-TLH or LESS-LAVH. Surgical outcomes were assessed and compared between the two groups. There were no differences in baseline demographics between the two groups. Surgical outcomes such as operative time, estimated blood loss, length of hospital stay, and complication rate were similar between the two groups. The failure rate in the LESS-TLH group was higher than that in the LESS-LAVH group (5/38 [11%] versus 0/38 [0%]), although this difference did not reach statistical significance (P=.054). Among the 5 cases that failed in the LESS-TLH group, 4 were related to a large lower uterine segment prohibiting visualization during colpotomy. The postoperative pain scores at 18 and 36 hours after surgery were significantly lower in the LESS-TLH group than in the LESS-LAVH group (all P<.001). Vaginal discharge at 1 and 4 weeks after surgery was significantly lower in the LESS-TLH group than in the LESS-LAVH group (all P<.001). LESS-TLH and LESS-LAVH are both safe, feasible procedures with similar surgical outcomes. LESS-TLH was associated with less postoperative pain and less postoperative vaginal discharge, whereas LESS-LAVH may be preferred in patients with a uterus with a large lower uterine segment.

    ABSTRACT: The length of incisions on the abdominal wall directly correlates with wound-related morbidities and patient comfort. Both mini-laparoscopy (only ≤5-mm trocars) and natural orifice specimen extraction avoid larger abdominal incisions. This study described a new natural orifice translumenal endoscopic surgery (NOTES(®); American Society for Gastrointestinal Endoscopy [Oak Brook, IL] and Society of American Gastrointestinal and Endoscopic Surgeons [Los Angeles, CA]) cholecystectomy technique by combination of these two advanced laparoscopic techniques for cholelithiasis in patients who had prior laparoscopic Roux-en-Y gastric bypass (LRYGB) for obesity. Three patients (two males, one female; 39, 62, and 34 years old, respectively) were admitted with symptomatic cholelithiasis (multiple millimeter-sized gallstones), and all had previously had LRYGB. They were treated by mini-laparoscopic cholecystectomy using three 5-mm trocars. The gallbladder was removed through the dilated efferent limb of the jejunum, 5 cm distal from the gastrojejunostomy. Transjejunal extraction was performed under endoscopic guidance. The gallbladder in the jejenum was passed through the anastomosis and extracted with an endoscopic snare by the transoral way. The enterotomy was closed intracorporeally. There was no conversion or additional trocar requirement. All the procedures were completed successfully without problems. Respective operating times were 95, 75, and 120 minutes. Only 1 patient required postoperative analgesic; the others did not. The patients started to get a liquid diet on the night of surgery and were discharged on Days 1, 1, and 2, respectively, with normal diet recommendations. There were no morbidities. Mini-laparoscopic cholecystectomy is technically feasible in patients with previous LRYGB. Prior LRYGB was not an obstacle for transoral specimen extraction. The dilated efferent jejunal limb is a good alternative route for natural orifice specimen extraction. This report described the first natural orifice surgery through the small bowel.

    ABSTRACT: A prospective randomized comparison of three-dimensional (3D) versus two-dimensional (2D) imaging during elective laparoscopic cholecystectomy (LC), both performed separately by an advanced laparoscopic surgeon and by a surgeon experienced in open surgical procedures but a novice at laparoscopic procedures, was designed to address the issue of whether 3D systems offer real operative time advantages to this laparoscopic procedure. Eighty patients were randomized the day of surgery by random computer-generated allocation list to receive either a 3D or 2D high-definition imaging system LC by two surgeons with differing experience. After the insertion of the access ports the surgical procedure was divided in two component tasks. Operative times of the two component tasks and the entire procedure were recorded. The execution times for the two component tasks and the entire procedure were not significantly different between the 2D and 3D groups for the experienced laparoscopic surgeon. However, the execution times for the two component tasks and the entire procedure were significantly faster during 3D compared with 2D for the novice surgeon. Both surgeons experienced better depth perception with the 3D system and subjectively reported less strain using 3D rather than 2D vision. 3D imaging seems not to influence the performance time of LC by an experienced laparoscopic surgeon. Less experienced laparoscopic surgeons could benefit from shorter performance time with 3D imaging due to no need to adapt to 2D vision. Further comparative studies are necessary to verify on great numbers of cases whether 3D can reduce intraoperative complications such as biliary lesions.

    ABSTRACT: Laparoscopic distal pancreatectomy (LDP) is replacing open surgery as the technique of choice for benign and premalignant lesions of the left pancreas. In most laparoscopic series, the supine decubitus or semilateral position is preferred. A posterior approach with the patient in full right lateral decubitus (PA-FRLD) has been proposed as an alternative. From July 2012 to November 2014 we performed 14 LDPs. PA-FRLD was chosen in 8 patients; in 6 patients splenectomy was also performed. Definitive diagnoses were 3 cases of pancreatic ductal adenocarcinoma, 2 cases of nonfunctioning neuroendocrine tumors, 1 case of bulky serous cystic neoplasm, 1 case of inflammatory chronic pancreatitis, and 1 case of pancreatic trauma (duct disruption). No conversions were required. No postoperative pancreatic fistula was detected. No patient required transfusion. Two patients had Clavien II and IIIb postoperative complications. In both cases in which preservation of the splenic vessels was attempted, it was successfully achieved. The PA-FRLD position is a valid alternative to the supine or semilateral position for LDP. This approach is especially beneficial for resection of complex and bulky lesions of the tail of the pancreas and those in close contact with retroperitoneal organs and can also facilitate spleen-preserving LDP.

    ABSTRACT: Natural orifice translumenal endoscopic surgery (NOTES(®); American Society for Gastrointestinal Endoscopy [Oak Brook, IL] and Society of American Gastrointestinal and Endoscopic Surgeons [Los Angeles, CA]) is gaining interest because it allows operations without skin incisions. The aim of this study was to evaluate the feasibility, safety, and cosmetic results of endoscopic thyroidectomy via the oral vestibular approach (ETOVA) compared with endoscopic thyroidectomy via the areola approach (ETAA) in patients with thyroid diseases. Eighty-two patients with thyroid diseases were randomized to receive either ETOVA (n=41) or ETAA (n=41). Perioperative and follow-up data were assessed. The surgery was completed in all cases, and all patients were followed up for at least 1 year. There were no differences between the two groups in operation time, blood loss, or postoperative hospital stay. Respective pain scores were 1.7 versus 2.1 and 0.6 versus 0.8 on Days 1 and 3, respectively, postoperatively. The white blood cell counts and C-reactive protein levels were not significantly different between the two groups. Complications were the same in both groups. Oral incision scars were invisible in the ETOVA group. Rates of skin traction sensation on the surgical field were lower in the ETOVA group than in the ETAA group at 3 and 6 months postoperatively (53.7% versus 80.5% and 24.4% versus 46.3%, respectively). The respective satisfaction score was 9.61 versus 9.22 (P=.021). No recurrent cases were observed in the study. Both the ETOVA and the ETAA procedures are feasible for thyroid diseases. The ETOVA eliminated skin incision scars and gained better cosmetic results in the short-term follow-ups, and the trauma was the same between the two approaches. However, more cases and longer-term follow-ups are needed for confirmation.

    ABSTRACT: Minimally invasive surgical techniques are currently used for numerous urologic disorders and generally offer decreased morbidity and equivalent outcomes compared with open surgery. There is a relative paucity of data on robot-assisted ureteral re-implantation (RAUR) in adult patients for benign stricture disease. We retrospectively reviewed our recent experience with mid-/distal ureteral reconstruction at a single tertiary-care center. From 2010 to 2012, 13 consecutive patients presenting with benign obstruction of mid-/distal ureters were managed with RAUR. In all cases the operative procedure was undertaken with six-port transperitoneal access, and all procedures were completed robotically. All ureters (left, n=5; right, n=7; bilateral, n=1) were re-implanted in a standard Bricker fashion into the dome of the bladder with (n=8) or without (n=6) a psoas hitch. Catheters were removed 4-11 days postoperatively, and all cystograms were negative for leak. Stents were removed 14-48 days after surgery. All were negative for hydronephrosis. Average follow-up was 10 (range, 2-20) months. There were two grade 1, two grade 2, two grade 3, and no grade 4 or 5 complications in 3 patients. RAUR is a safe and effective procedure. Extensive laparoscopic lysis of adhesions represents the primary challenge to an otherwise straightforward minimally invasive surgery. At our institution, RAUR has replaced open ureteral re-implantation as the preferred treatment for benign mid-/distal ureteral stricture disease.

    ABSTRACT: The aim of this study was to test and validate a novel noninvasive method for intraoperative visualization of extrahepatic bile ducts during laparoscopic cholecystectomy. Injury to the common bile duct (CBD) is a rare but major complication of laparoscopic cholecystectomy. Most injuries occur when anatomy is unclear due to the presence of anatomic variations, acute inflammation, or adhesions. Thirty patients were included, and each received an intravenous injection of 0.05 mg/kg of indocyanine green (ICG) (ICG-Pulsion(®); PULSION Medical Systems AG, Munich, Germany) prior to the start of surgery. Laparoscopic cholecystectomy was performed according to standard procedures. The CBD and cystic duct (CD) were visualized before and during dissection of the liver hilus using a conventional laparoscopic camera and a recently developed near-infrared (NIR) camera (Olympus, Tokyo, Japan). Using ICG-NIR, the CBD and CD could be visualized 11 minutes (P=.008) and 8.6 minutes (P=.001) earlier than with a conventional camera. Both early (20/30 patients) and late (26/30 patients) identification of the CBD with ICG-NIR was significantly more frequent compared with conventional images (2/30 and 10/30, respectively; P<.001). One postoperative bilioma required re-admission and endoscopic retrograde cholangiopancreatography with stent placement. Identification of the CBD and CD using a low dose of ICG and the NIR camera was both faster and more frequent compared with conventional laparoscopic images during elective laparoscopic cholecystectomy.

    ABSTRACT: To report the preliminary experience of laparoscopic radical nephrectomy (LRN) in children with Wilms' tumor (WT) and renal cancer. From January 2010 to October 2013, the medical records of 7 cases of WT or renal cancer in children treated by LRN at two medical centers in China were reviewed. All the patients were treated by LRN, and 3 of them underwent preoperative chemotherapy before surgery. The biggest tumor size was 10 cm without crossing the lateral edge of the vertebra at the time of operation. The median hospital stay was 8.5 days (range, 6-11 days). The pathologic investigation showed 5 cases of WT, 1 case of rhabdoid tumor, and 1 case of renal cell carcinoma. With a median follow-up of 1.9±1.5 years (range, 0.3-2.9 years), six children were in complete remission, and the remaining one was lost to follow-up. None of these patients presented evidence of oncological complications (tumoral recurrences, port-site implantation, or secondary lung metastases), and no small bowel obstruction occurred. LRN for WT and renal cancer may be considered as an option in selected children. Preoperative chemotherapy is to decrease tumor size and to facilitate the dissection, avoiding tumor rupture. For trained laparoscopic surgeons, the eventual indication of LRN is the tumor not crossing the midline. A long follow-up and more cases are necessary to evaluate the results of the laparoscopic approach.
