Journal of Laparoendoscopic & Advanced Surgical Techniques

Cloaca malformation repair strategy is strongly dictated by common channel and urethral lengths. Mid to long common channel cloacas are challenging and often require laparotomy for dissection of pelvic structures. The balance of common channel and urethral lengths often dictates the approach for reconstruction. Laparoscopy has been utilized for rectal dissection but not for management of the urogenital (UG) structures. We hypothesized that laparoscopy could be applied to UG separation in reconstruction of cloaca malformations.

Records were reviewed for 9 children with cloaca who underwent laparoscopic rectal mobilization and UG separation. Clinical parameters reviewed included demographics, relevant anatomic lengths, operative duration, transfusion requirements, and perioperative complications.

Repair was perfomed at a median (interquartile range) age of 12 (7, 15) months. Common channel length as measured by cystoscopy was 3.5 (3.3, 4.5) cm. There were no intraoperative complications. Transfusion requirements were minimal. Postoperative length of stay was 6 (5, 11) days. One patient developed a urethral web and 2 developed vaginal stenosis. One patient later underwent a laparotomy for obstruction due to a twisted rectal pull-through.

Laparoscopic rectal mobilization and UG separation in long common channel cloaca are safe and well tolerated. Laparoscopy affords full evaluation of Mullerian structures and enables separation of the common UG wall, which may ultimately enhance long-term urinary continence.

This study set out to assess the efficacy of three different approaches to simulation-based minimal access surgery (MAS) training using a three-dimensional printed neonatal thoracoscopic simulator and a virtual simulator.

Randomized controlled trial of medical students (N = 32), as novices to MAS. The participants performed two construct validated tasks on a thoracoscopic simulator and were then randomly allocated into four intervention groups: (1) three consultant-led sessions on a thoracoscopic simulator; (2) three self-directed learning sessions on the same simulator; (3) self-directed “virtual training” on the “SimuSurg” application; and (4) control. Postintervention participants repeated both tasks. Videos of all task attempts were de-identified and marked by a blinded consultant pediatric surgeon.

There were no statistically significant differences in baseline objective structured assessment of technical skills (OSATS) scores or demographics in any group. For the “ring transfer” task, Groups 1 and 2 showed significant improvement after intervention, with no significant change in Groups 3 or 4. There was no significant difference between Groups 1 or 2 in postintervention scores. For the “needle pass” task, no group demonstrated a statistically significant improvement after intervention.

Practice on a physical simulator either consultant-led or self-directed led to improved scores for MAS novices compared with a virtual simulator or no intervention for a simple “ring transfer” task. This suggests that time on the physical simulator was the most important factor and implies that trainees could usefully practice simple tasks at their convenience rather than require consultant supervision. This improvement is not seen in more challenging tasks such as the “needle pass.”

Minimal esophageal mobilization during laparoscopic fundoplication decreases the rate of wrap transmigration, and previous study has shown that placement of esophageal-crural sutures does not offer any advantages in preventing wrap migration. Our aim was to determine the need for posterior crural sutures during laparoscopic fundoplication.

This was a retrospective review of patients >1 month old who underwent a primary laparoscopic fundoplication from 2010 to 2019. Demographic, surgical, and outcome data were recorded. Primary outcome was transmigration of the fundoplication wrap. Analysis was performed using STATA^® (StataCorp, College Station, TX); P value <.05 was significant.

There were 181 patients included. The median age was 7.2 months (interquartile range [IQR] 3.7, 17.0) with 59% being male patients. Sixty-one (34%) patients received posterior crural stitches and 120 (66%) did not receive stitches according to staff preference. The stitch group had a median of 1 (IQR 1, 1) posterior crural stitches placed. There was no difference in the incidence of wrap migration, the number of patients requiring a workup for recurrent symptoms, or reoperation between the two groups (Table 1). A significantly higher percentage of patients in the no-stitch group underwent concurrent procedures; when controlled for this, there was no difference in the median operative time between the groups (P = .18).

The placement of crural sutures, including the posterior crural suture, does not prevent wrap migration and may not be necessary for prevention of wrap herniation in pediatric fundoplication.

To clarify the characteristics of patients with rectal prolapse after laparoscopically assisted anorectoplasty (LAARP), estimate the causes, and evaluate its impact on postoperative bowel function.

The medical records of patients who underwent LAARP for high- or intermediate-type anorectal malformation between 2000 and 2019 were retrospectively reviewed. Clinical data were compared between patients with (Group P) and without prolapse (normal, Group N). Fecal continence was evaluated using the clinical assessment score for fecal continence developed by the Japanese Study Group of Anorectal Anomalies. For patients who underwent pelvic magnetic resonance imaging (MRI) before LAARP, atrophy, or asymmetry of the anal sphincter and levator ani was evaluated by a radiologist.

Of the 49 patients, 29 (59%) had rectal prolapse after LAARP (Group P) and 20 did not (Group N). We found no significant difference in gender, type of malformations, incidence of associated spinal or lumbosacral anomalies, procedure time, and postoperative bowel function at ages 4, 8, 12, and 16 years. However, LAARP was performed significantly earlier in Group N (median [range], 180 [123–498] days) than in Group P (210 [141–570] days). In Group P, 18 patients (62%) developed prolapse before colostomy takedown. Eight of 26 patients who underwent surgical prolapse repair required redo procedures. Twenty-five patients who underwent preoperative pelvic MRI showed no significant relationship between the muscular abnormalities and the incidence of postoperative rectal prolapse.

Although recurrence is common, performing LAARP at a younger age might prevent postoperative prolapse development.

The Japanese endoscopic surgical skill qualification system (ESSQS) in pediatric surgery was started 10 years ago to encourage safe and appropriate pediatric minimally invasive procedures and avoid severe complications. The present study investigated the impact of the ESSQS on the incidence of serious complications in the field of pediatric endoscopic surgery.

We sent a questionnaire to institutes belonging to the Japanese Pediatric Endoscopic Surgery Group. Institutes were divided into two groups: institutes with (Group A) or without (Group B) ESSQS-qualified pediatric surgeons at any point in the last 10 years. Intraoperative complications (grade 3 and 4 under the Classification of Intraoperative Complications [CLASSIC] classification), postoperative complications (grade ≥IIIb under the Clavien/Dindo classification), and the number and rate of endoscopic procedures and complications of advanced and common procedures were compared between the two groups. This study is an exempt survey since no patient identifier has been collected.

We collected answers from 46 of 102 institutes (response rate: 45%) (Group A: 18 institutes, Group B: 28 institutes). Intra/postoperative complications were significantly more frequent in Group A than in Group B (P = .02 and P < .001, respectively). Endoscopic operations accounted for a larger proportion of advanced and common surgeries in Group A than in Group B, and the rate of postoperative complications of advanced procedures was significantly higher in Group A than in Group B (P = .012).

While endoscopic surgery was performed more frequently in Group A than in Group B, the incidence of intra/postoperative serious complications was significantly higher in Group A. The current Japanese ESSQS was unable to markedly reduce the rate of serious complications.

Pediatric foreign body ingestion remains a common reason for emergency department (ED) visits. Button battery ingestion is an established surgical emergency, requiring immediate removal. Timing of removal for other foreign bodies remains controversial. We hypothesize that there is no difference in complication rate or successful removal of esophageal foreign bodies that wait until the following morning for removal.

A retrospective review for cases involving esophageal foreign body removal by pediatric surgery or pediatric gastroenterology from November 2015 to November 2019 was performed. Patients were divided into two groups based on ED arrival—daytime (05:00–16:59); nighttime (17:00–04:59). Imaging confirmed an esophageal foreign body. Data collected included basic demographics, time of presentation, time of procedure, symptoms, location of the foreign body, and complications within 30 days. Statistical analysis was performed.

After excluding button batteries, 273 children underwent esophageal foreign body removal. Two-thirds presented at night. A significant difference was identified in the median time from ED to the operating room when comparing daytime (194.8 minutes; interquartile range [IQR]: 108.5–347) versus nighttime groups (643 minutes; IQR: 471.5–745; P < .001). Nine children had a complication or readmission within 30 days of their procedure and 25 patients had migration of their foreign body into the stomach, both with no significant difference (P = .94; P = .98, respectively).

We found that waiting until the following morning had minimal impact on complications or success rate when removing esophageal foreign bodies. By waiting, institutions with limited personnel can keep resources and staff available for more pressing emergencies.

Thoracoscopic repair of esophageal atresia (EA) is gaining popularity, but it is a highly technically demanding procedure. The aim of our study is to evaluate our outcomes in the management of type C EA comparing the thoracoscopic and the open (thoracotomy) approaches.

This is a retrospective bicentric study of two major pediatric surgery centers, reviewing all the patients operated for EA with distal tracheoesophageal fistula. Only patients who underwent primary anastomosis were included. From 2008 to 2018, 187 patients were included.

Forty-seven patients were operated thoracoscopically (TS group) and 140 by the open approach (TT group). Mean gestational age was 38 ± 2.4 weeks in TS group and 36.4 ± 3.3 weeks in TT group (P = .005) with a mean birth weight of 2785 ± 654 g and 2404.9 ± 651 g in TS and TT groups, respectively (P = .003). The mean operative time was 127.6 ± 35 minutes in TS group and 105.7 ± 23 minutes in TT group (P = .0005). The mean postoperative ventilation time and the mean length of stay were significantly shorter in the thoracoscopic group (P = .004 and P < .0001, respectively).

The incidence of anastomotic leak was 8.9% in TS group versus 16.4% in TT group (P = .33). Anastomotic stenosis occurred in 33.3% of TS group and in 22.4% of TT group (P = .17).

Surgical outcome of thoracoscopic repair of EA is comparable to the open repair with no higher complication rate with the expected skeletal and cosmetic benefits. However, possible bias regarding prematurity, weight at surgery, and associated anomalies must be taken into consideration.

Anastomotic leak (AL) rates gradually decreased with surgical skills and perioperative management progression, but it is still inevitable. As the traditional management of AL after the pull-through procedure of Hirschsprung's disease (HD), enterostomy could lead to multiple surgeries, repeated hospitalizations, increased costs, and enterostomy-associated complications. This study aimed to explore the safety and feasibility of resuturing without enterostomy treating early AL after the laparoscopic Soave procedure.

From October 2014 to June 2019, 10 patients who had AL after the laparoscopic Soave procedure were included. Six patients underwent simply resuturing with presacral drainage; the reoperation time was 1–5 days after primary surgery. Four patients who had diffused peritonitis or severe inflammations received resuturing with an ileostomy, and the reoperation time was 6–11 days.

Common early symptoms of AL included persistent fever, sacrococcygeal pain, and abdominal pain. The median delay to reoperation was 1.0 (0–2.25) day. Five patients had leaks at the 3–6 o'clock position, two had leaks at the 6–9 o'clock, and the other three had leaks at the 6 o'clock. The median postoperative fever durations were similar in patients without or with an ileostomy, and the median length of intensive care unit (ICU) stays, duration of antibiotic use, and postoperative length of stay were significantly longer in patients with ileostomy. The mean follow-up time was 38.5 ± 16.7 months (15–69 m). As of the time of writing, no reoccurrence was identified.

For patients without diffuse peritonitis, severe inflammations, early diagnosis and timely resuturing of AL within 5 days after the laparoscopic Soave procedure of HD could be a safe, effective, and pleasing treatment.

To compare the effects of retrograde intrarenal surgery (RIRS) and percutaneous nephrolithotomy (PNL) on postoperative pain and their differences in terms of the postoperative need for analgesics in the treatment of 2–4 cm kidney stones.

A total of 132 patients who suffered from renal stones 2–4 cm in size and had surgery at our urology clinic between April 2015 and April 2017 were enrolled in this prospective study (NCT02430168). Patients were randomized into either the RIRS group (Group 1) or PNL group (Group 2) in a ratio of 1:1. Postoperative visual analog scale (VAS) values at 8 and 24 hours postoperatively and analgesic treatments of patients were recorded.

Patients from both groups had similar demographic characteristics. Stone-free states were achieved in 37 (74%) patients in the RIRS group and 45 (90%) patients in the PNL group. Postoperative complication rates were similar in two groups. Moreover, there was no statistically significant difference between the groups in terms of the postoperative need for analgesics (P = .309). However, the PNL group had higher VAS values (P < .001).

Although the early postoperative pain scales were high in the PNL group, there was no significant difference between the groups in terms of the standard analgesic treatments for achieving patient's comfort. PNL, which has similar complications, but with higher success rates, compared with RIRS, did not require additional analgesic treatment during postoperative pain management. Thus, in our opinion, PNL should still remain as a first choice in treatment of 2–4 cm renal stones.

Evaluate the quality of life (QoL) in patients diagnosed with achalasia who performed Heller's myotomy.

Between January 1, 2000 and March 27, 2019, 99 patients were submitted to esophagomyotomy at the São João Hospital in Oporto, Portugal. The exclusion criteria were other diagnoses, age <18 years at the date of surgery, and death. Seventy-five patients were contacted. Pre- and postoperative evaluations were performed using the achalasia disease-specific QoL questionnaire and by the Eckardt score. QoL was assessed by the Medical Outcomes Study SF-36.

Forty-nine patients (65%) answered the questionnaires. The median difference in the achalasia-DSQoL questionnaire between the pre- and postoperative period was −9.0 (interquartile range [IQR]: 5–12), whereas in the Eckardt score was −5.0 (IQR: 3.25–7). Lower postoperative scores correlated with higher scores on the SF-36's mental and physical summary measures (Spearman's rho [ρ] = −0.651 and ρ = −0.577 for the achalasia-DSQoL questionnaire and ρ = −0.552 and ρ = −0.515 for the Eckardt score, P < .001). Physical and mental summary measures were correlated with each other (ρ = 0.788, P < .001).

Heller's myotomy allows a decrease in symptoms and an increase in QoL. Patients with severe symptoms before surgery had higher postoperative scores and patients with fewer symptoms had lower postoperative scores.

To compare the surgical feasibility, oncological and functional results between sutureless and suture techniques in retroperitoneal laparoscopic nephron-sparing surgery (LNSS).

This retrospective study collected consecutive patients with a renal mass who underwent retroperitoneal LNSS in two high-volume centers. Propensity score matching (PSM) analysis was conducted to select two baseline homogeneous cohorts. Descriptive statistics was performed both before and after PSM. Moreover, univariate and multivariate logistic analyses were carried out to identify the risk factors of postoperative acute kidney injury (AKI), whereas Kaplan–Meier analysis for functional deterioration (new-onset stage 3 chronic kidney disease [CKD], estimated glomerular filtration rate [eGFR] <60 mL/min/1.73 m², or CKD upstaging after surgery) was utilized to compare the two cohorts.

After PSM at a ratio of 1:3, the sutureless group (n = 65) was compared with the suture group (n = 152) with no remaining statistically significant differences in baseline characteristics. With regard to patient outcomes, differences in warm ischemia time (WIT) (P < .001), estimated blood loss (P < .001), AKI (P = .002), length of hospital stay (P = .020), and eGFR at discharge (P < .001) were statistically significant. Meanwhile, the postoperative complication rates (9.2% versus 13.8%, P = .378) and positive surgical margins (0% versus 2.0%, P = .556) were not statistically different. At the last follow-up, the eGFR decline percent was the same (−1.5% versus −2.2%, P = .192). No difference was detected on Kaplan–Meier analysis for functional deterioration (log-rank test, P = .304).

Sutureless technique in LNSS is safe and feasible, compared with the traditional suture method, with shorter WIT, lower AKI rate, and comparable long-term oncological and functional outcomes.

Increased popularity of one-anastomosis gastric bypass (OAGB) is associated with increased reports on the procedure-related complications. Protein-energy malnutrition (PEM) is a serious complication that may mandate reversal. The primary outcome of this study is the outcome of surgical management of PEM after OAGB.

A retrospective cohort study of patients presented with PEM after OAGB between January 2014 and December 2018. Patients with a biliopancreatic limb (BPL) >200 cm were excluded. PEM was diagnosed based on the Global Leadership Initiative on Malnutrition criteria. Indications for reversal of OAGB due to PEM included failure of conservative measures, intolerable symptoms, and hepatic decompensation.

Eight patients presented with PEM and were reversed to normal anatomy or Roux-en-Y gastric bypass. The incidence of postoperative 30-day complications in this series was 37.5% (n: 3/7). Postoperative mortality due to hepatic cell failure occurred in 1 patient. Two patients deceased before reversal, one secondary to severe soft tissue infection, whereas the cause of death could not be confirmed for the second.

Socioeconomic status and thorough preoperative counselling are important to predict patient commitment to postoperative supplementations and laboratory investigations. Bariatric teams should apply innovative methods as telemedicine to make patient compliance easier. The etiology of PEM cannot be purely explained by the BPL length. Revisional surgery is mandatory for resistant, recurrent, or complicated PEM.

The aim of this prospective, nonrandomized, observational study was to present our results in operative treatment of complex anal fistulas using video-assisted anal fistula treatment (VAAFT) procedure with a curative intent in 2 years follow-up period.

Between March 2016 and March 2018, 73 patients underwent the VAAFT procedure. Postoperative follow-up was 2 years, up to March 2020. Only patients with complex cryptoglandular anal fistulas were included. All patients were referred for magnetic resonance imaging of the pelvis. Fecal incontinence severity index score was used to assess any continence disturbance prior operation and postoperatively.

Primary healing occurred in 52 cases (71.23%) after first operation. From 21 patients who had recurrence or who had persisting disease, 16 patients accepted reoperation with second VAAFT procedure and additionally 10 patients achieved healing. From a total number of 73 patients who were included in study healing ultimately occurred in 62 cases (84.93%). In the first operation internal opening was identified in 47 cases (64.38%) and was closed with mattress suture, rectal advancement flap or ligation of intersphincteric fistula tract technique depending on its extent and type of fistula. Median primary healing rate was 6 weeks. There were no serious intra- or postoperative complications. None of the patients reported any type of continence disturbance.

VAAFT has been shown to offer good rates of healing, low morbidities, possibilities of multiple attempts in case of first failure and this series adds to the literature.

The diagnosis of occult penetrating diaphragmatic trauma remains challenging, with conventional imaging offering inadequate accuracy for diagnosis. Minimally invasive surgical options for evaluating the diaphragm conventionally require general anesthesia. We propose a technique for evaluating the diaphragm via awake thoracoscopy in the emergency department.

A prospective interventional study was conducted to investigate the safety and accuracy of emergency department awake thoracoscopy for diagnosing diaphragmatic injuries in penetrating thoracoabdominal trauma. All adult patients who presented to the trauma unit with penetrating thoracoabdominal trauma who were hemodynamically stable were enrolled. The patients underwent emergency department awake thoracoscopy with a rigid endoscope through a previously inserted intercostal drain. Only local anesthesia and conscious sedation were provided.

Forty patients were enrolled. All 40 (100%) were men, and the median age was 34 years. Thirty-four had stab wounds (85%), 5 had gunshot wounds (12.5%), and 1 had a suspected iatrogenic diaphragm injury during intercostal drain insertion (2.5%). In 32 (80%), the diaphragm was well visualized, of whom 7 (17.5%) had diaphragm injuries. In the remaining 8 patients in whom the diaphragm was not well visualized, only 1 (2.5%) had a diaphragmatic injury. The diaphragmatic injuries that were identified were confirmed and repaired during a subsequent explorative laparoscopy. There were no procedure-related complications in any of the patients during short-term follow-up.

Awake thoracoscopy is safe, feasible, and accurate for the diagnosis of occult diaphragm injuries and may offer a modality for assessment that does not require general anesthesia.

Urinary system stone disease is an important health problem. It has been reported to have a prevalence of 14.8% in Turkey. The aim of the renal stone removal surgery is to clear the stones with minimal complications. Retrograde intrarenal surgery (RIRS) is a safe method due to the fewer and minor complications. As a clinic in central Anatolia, we aimed at researching the factors affecting RIRS success in our area.

After local ethics committee's approval, the data of the patients who had undergone RIRS between 2014 and 2019 were reviewed. Patients who were <18 years old, had kidney anomalies, and had both ureter and kidney stones were excluded from the study. The patients who were defined as successful were named as Group 1 and the others were named as Group 2. The demographic, intraoperative, and postoperative data of the two groups were compared.

There were a total of 416 patients in our study. Group 1 consisted of 332 patients, whereas Group 2 had 84 patients. Opacity was significantly different between the groups (P = .004). Stone size, stone volume, and operation time were significantly higher in Group 2. After logistic regression analysis, we found that stone size, opacity, and operation time affected the success of RIRS significantly (P < .05). There was a reverse relationship with stone size, operation time, and opacity.

We believe that in patients who have large lower calix stones and who want effective treatment, percutaneous nephrolithotomy should still be an option for treatment.

The rates of incidental appendiceal neoplasms after appendectomy performed for acute appendicitis is <2%. To date, no large studies have investigated the preoperative risk factors or imaging findings associated with incidental appendiceal tumors that present as appendicitis. Our study aims to identify preoperative factors that are associated with an increased risk of appendiceal tumors in patients who present with signs and symptoms of acute appendicitis.

Using the targeted appendectomy American College of Surgeons National Surgical Quality Improvement Program database, we identified patients who underwent nonelective appendectomy for acute appendicitis in 2016. Patients with final pathology consistent with a tumor were compared with those with only appendicitis. A nonmatched case/control method was used to pull a random sample from the appendicitis cohort using a 1:4 ratio (tumor: acute appendicitis) to obtain adequate power for comparison. Preoperative patient variables and imaging findings were investigated using stepwise logistic regression to identify variables associated with appendiceal tumor.

Following multivariate analysis, preoperative imaging read of “indeterminate” and “not consistent with appendicitis,” female gender, increased age, and lower preoperative white blood cell (WBC) count were significant predictors of tumor causing symptoms of appendicitis. The odds of having tumor pathology were significantly increased in patients with preoperative imaging of “indeterminate” and “not consistent with appendicitis.” The odds of having tumor pathology were 82% higher for females than for males, increased by 2% for every 1-year increase in age, and increased by 3% for every one-unit decrease in WBC count.

While incidental appendiceal tumors can present as acute appendicitis, 3 patient variables and one imaging finding were identified that may increase suspicion for appendiceal tumors. Consideration should be given to patients with these associated risk factors for additional preoperative consultation in addition to the potential for intraoperative pathology consultation.

Transanal total mesorectal excision (TaTME) carried out synchronously with laparoscopy is a useful surgical technique in rectal cancer patients who are overweight or who have a narrow pelvis. This retrospective study aims to compare the safety and efficacy of two-dimensional (2D) and three-dimensional (3D) laparoscopic TaTME of rectal cancer based on the short-term postoperative and oncological outcomes of 40 patients in Singapore who underwent laparoscopic TaTME.

Forty patients underwent laparoscopic TaTME for rectal cancer in one of three centers in Singapore from October 2015 to August 2018. Out of these patients, 23 underwent 3D laparoscopic TaTME with the Olympus Flexible Tip™ 10 mm scope. Data on patient demographics, operative details, and postoperative and oncological outcomes were collected retrospectively by going through soft copy patient records, analyzed and compared.

The operative time for 3D group was significantly shorter (340 versus 419 minutes, P = .04). Complete TME grade and R0 resection was achieved in a higher percentage of patients in the 3D group although this was not statistically significant. There were no other significant differences between the two groups in terms of oncological outcomes and other short-term postoperative outcomes.

TaTME is overall a safe technique. Three-dimensional TaTME for rectal cancers is as safe and feasible as 2D TaTME, with the advantage of a shorter operative time.

Despite recent advances in the field of laparoscopic liver surgery, intrahepatic cholangiocarcinoma (iCC) as an entity has been nearly exempted from the new approaches because of proposed technical difficulties in achieving lymphadenectomy (LAD) and beneficial oncologic outcomes.

Clinical courses of all consecutive patients (n = 159) undergoing liver resection for iCC at the Department of Surgery, Charité—Universitätsmedizin between January 2015 and October 2019 were studied. Ultimately, after applying selection criteria 27 laparoscopic liver resections were compared with 31 open liver resections.

Preoperative patient characteristics were similar with regard to general health and tumor characteristics. However, patients in the laparoscopic group tended to have more advanced liver fibrosis. When LAD was performed laparoscopically, a median of eight lymph nodes were resected, complying with current AJCC treatment guidelines. Patients undergoing laparoscopic resection showed lower overall morbidity contributing at least in part to a markedly decreased hospital stay.

Herein, we report on one of the largest series of laparoscopically resected iCC, with a high proportion of major resections. Our data show laparoscopic resection to achieve noninferior outcomes to open resection despite impaired preoperative liver function.
