Single Anastomosis Sleeve Jejunal Bypass in Acute Mesenteric Artery Syndrome: A Case Report.

Superior mesenteric artery syndrome is a rare vascular compression syndrome in which the duodenum is compressed between the aorta and the overlying superior mesenteric artery. This condition is often chronic and secondary to cachexia. It can trigger further weight loss due to the subsequent proximal intestinal obstruction, causing a positive feedback loop. We report a case of acute presentation of superior mesenteric artery syndrome, complicated by gastric necrosis and treated surgically using the principles of a novel bariatric procedure.

Protocol of the LATFIA trial (Laser Assisted Treatment of Fistula in Ano): a multicentre, prospective, randomized controlled trial comparing fistula-tract laser closure (FiLaC™) with rectal advancement flap for high trans-sphincteric fistulas.

AIM: Anal fistula is one of the most common anal diseases, affecting between 1 and 3 per 10 000 people per year. Symptoms have a potentially severe effect on a patient's quality of life. Surgery is the mainstay of treatment, aiming to cure the fistula and preserve anal sphincter function. Rectal advancement flap (RAF) is currently the gold standard treatment but has recurrence rates varying between 20% and 50% and might lead to disturbance of continence. The aim of the trial described in this work is to discover if the minimally invasive fistula tract laser closure (FiLaC™) technique could achieve higher healing rates and a better functional outcome than RAF. METHOD: We will perform a randomized prospective multicentre noninferiority study of the treatment of high trans-sphincteric perianal fistulas, comparing FiLaC™ with RAF in terms of fistula healing, recurrence rate, functional outcome and quality of life. Primary and secondary fistula healing will be evaluated at 26 and 52 weeks' follow-up. Quality of life will be evaluated using the SF-36 questionnaire, the Faecal Incontinence Quality of Life Scale questionnaire and the Vaizey score at 3, 6, 12 and 26 weeks postoperatively. CONCLUSION: High trans-sphincteric fistulas have a potentially severe effect on a patient's quality of life. Classical treatment with RAF is a time-consuming invasive procedure. The LATFIA trial aims to compare FiLaC™ with the gold standard treatment with RAF. In case of noninferiority, FiLaC™ treatment could be standardized as a first line treatment for high trans-sphincteric fistulas. Better conservation of the patient's anal sphincter function could possibly be obtained. Likewise, we will report on the postoperative quality of life when applying these two techniques.

Does minimally invasive laser-assisted treatment of pilonidal sinus disease live up to its expectations: a multi-center study with 226 patients.

PURPOSE: The minimally invasive character, the possibility to perform under local anesthesia, and the ease to repeat have led to increasing popularity of laser-assisted treatment of pilonidal sinus disease. Hereby, potentially avoiding prolonged need for medical care at home, incapacity to work, and high expenses for patients and society. This retrospective, multi-center study is aimed at evaluating the feasibility of laser-assisted treatment for pilonidal sinus disease. METHODS: The patient population is comprised of all patients undergoing laser-assisted treatment of pilonidal sinus disease at three Belgian hospitals between January 2017 and December 2021. Data were retrospectively collected. The primary endpoint was overall wound healing after one or more laser assisted procedures. RESULTS: A total of 226 patients were included with a mean follow-up time of 129 days [7-1120]. The healing rate after one laser procedure was 78.8%. Some of these patients were healed by a second or third procedure adding up to an overall healing rate of 85.4% after one or more laser procedures. Wound infections were the main postoperative complication (8.0%) of which 5 patients required drainage (2.2%). For 29 patients (12.8%), laser-assisted treatment was insufficient, leading to a secondary operation (drainage, excision, or flap). CONCLUSION: This study shows that laser-assisted treatment is feasible for pilonidal sinus disease. The minimally invasive character of this technique might make up for a higher non-healing rate compared to other techniques like flap repair. However, care must be taken that healing rate might be related to the presentation of the sinus and expectations should be lowered as presumed high healing rates are not always achieved.

HOW WE DO IT: the Keystone flap for large skin defects: our experience with 30 consecutive cases.

BACKGROUND: The keystone perforator-based fasciocutaneous island flap is a method of locoregional skin defect reconstruction, consisting of two conjoined V to Y advancement flaps. In this article, we report a series of 30 consecutive cases in various body parts with the aim to demonstrate the versatility of the keystone flap in the reconstruction of various skin defects after removal of a suspected malignant skin lesion and evaluate our clinical experience while maintaining oncological safety and good aesthetic results. METHODS: Patients who underwent keystone flap reconstruction between January 2016 and January 2021 were retrospectively reviewed. Their demographics, operative details, oncological data and postoperative details were obtained from the institution's internal electronic patient records system. RESULTS: The majority of the skin defects were the result of an oncologic resection (97%, n = 29) and were located in the pretibial region (47%, n = 14). In five cases (17%) there was a need for a double keystone flap to cover the skin defect. One or more risk factors (hypertension, smoking, anticoagulation, …) were identified in 22 patients (73%). Minor complications (partial wound dehiscence, effusion or surgical site infection) occurred in ten cases (33%) which were resolved with conservative wound management or systemic antibiotics. There were no major postoperative flap-related complications such as flap failure or need for re-surgery. CONCLUSION: In our experience, the keystone island flap is an effective and reliable technique to attain a single stage tension-free closure of large skin defects. Due to its low technical complexity and high success rate, we consider it a feasible alternative to other reconstructive flaps and grafts for direct closure of secondary defects.

LIFT: a feasible option for primary and recurrent fistulas.

BACKGROUND: The development of a surgical solution for anal fistulas with minimal recurrence and morbidity remains a challenge. Ligation of the intersphincteric fistula tract (LIFT), however, is a sphincter sparing technique that provides complete resolution of the transsphincteric fistula as well as minimizing recurrence and fecal incontinence. Our goal is to evaluate the efficacy of fistula tract ligation for primary and recurrent fistulas. METHODS: A retrospective single-center case study was conducted from data between 2015 and 2019 in a large district hospital in Antwerp, Belgium. Patients who underwent LIFT were included. Demographic patient data as well as primary outcome during the follow-up period were collected. A systematic literature review and analysis was conducted with terms [ANAL FISTULA] [TREATMENT] [LIFT] [LIGATION OF INTERSPHINCTERIC FISTULA]. Primary healing and recurrence associated with surgical modifications were investigated. RESULTS: 4 out of 25 patients presented with early failure (84% primary success rate) after a median follow-up period of 7 months. The median time until recurrence was 105 days. The success rate after a redo ligation was 100%. Twenty-eight studies were included for review and divided into three groups depending on the technical variation of the used technique. The success rate was 74.2% for the LIFT group, 72.9% in the LIFT + group, and 77.5% in the mLIFT group p = .92. CONCLUSION: LIFT is a feasible treatment option for primary and recurrent fistulas, with excellent success rates where fistula characteristics rather than chosen technique dictate the surgical outcome.

Mediastinal parathyroidectomy with the da Vinci robot.

Mediastinal parathyroid glands are often located in a position which is inaccessible through a cervical approach. Because of the significant morbidity of open surgery, the need for minimal invasive approaches is high. More recently, robotic systems have been introduced to refine the dissection and optimize the view in the mediastinal region. We present two cases. The first case is a 34-year-old woman who was diagnosed with primary hyperparathyroidism. Because a bilateral neck dissection disclosed no parathyroid adenoma, we performed a parathyroid sestamibi scan and computed tomographic scan of neck and mediastinum to look for aberrant parathyroid glands. Both showed a parathyroid adenoma in the mediastinum on the left side. The second case is a 66-year-old man. A sestamibi scan showed a parathyroid adenoma of 3 cm in the superior mediastinum which was confirmed by and computed tomographic scan. In both cases, we performed a parathyroidectomy with the da Vinci robotic system through a left-sided approach. Three thoracoports were inserted around the mammary gland for the robot and a fourth auxiliary port was positioned in between. Single-lung ventilation was installed, and the mediastinum was entered by opening the parietal pleura along the left phrenic nerve. The upper margin for dissection was the left brachiocephalic vein that was followed until the right pleura. All the tissue in front of the pericardium was dissected en bloc. The sinking test of the nodule and a preoperative frozen section analysis confirmed the diagnosis of parathyroid adenoma, which was also proven by rapid parathyroid hormone analysis. The resection of a parathyroid adenoma from the aortopulmonary window represents an ideal case for robotic surgery.

Laparoscopic adjustable banded roux-en-y gastric bypass as a primary procedure for the super-super-obese (body mass index > 60 kg/m²).

BACKGROUND: Currently, there is no consensus opinion regarding the optimal procedure of choice in super-super-morbid obesity (Body mass index, BMI > 60 kg/m²). Roux-en-Y gastric bypass (RYGB) is associated with failure to achieve or maintain 50% excess weight loss (EWL) or BMI < 35 in approximately 15% of patients. Also, percent EWL is significantly less after 1-year in the super-super-obese group as compared with the less obese group and many patients are still technically considered to be obese (lowest post-surgical BMI > 35) following RYGB surgery in this group. The addition of adjustable gastric band (AGB) to RYGB has been reported as a revisional procedure but this combined bariatric procedure has not been explored as a primary operation. METHODS: In a primary laparoscopic RYGB, an AGB is drawn around the gastric pouch through a small opening between the blood vessels on the lesser curve and the gastric pouch. The band is then fixed by suturing the gastric remnant to the gastric pouch both above and below the band to prevent slippage. RESULTS: Between November 2009 and March 2010, 6 consecutive super-super-obese patients underwent a primary laparoscopic adjustable banded Roux-en-Y gastric bypass procedure at our institution. One male patient (21 years, BMI 70 kg/m²) developed a pneumonia postoperatively. No other postoperative complications were observed. CONCLUSION: To the best of our knowledge, this is the first series of patients that underwent a laparoscopic adjustable banded RYGB as a primary operation for the super-super obese in the indexed literature. With the combined procedure, a sequential action mechanism for weight loss is to be expected. The restrictive, malabsorptive and hormonal working mechanism of the RYGB will induce weight loss from the start reaching a stabilised plateau of weight after 12 - 18 months. At that time, filling of the band can be started resulting in further gastric pouch restriction and increased weight loss. Moreover, besides improving the results of total weight loss, a gradual filling of the band can as well prevent the RYGB patient from weight regain if restriction would fade away with time.

Laparoscopic adjustable banded sleeve gastrectomy as a primary procedure for the super-super obese (body mass index > 60 kg/m2).

Isolated laparoscopic sleeve gastrectomy is increasingly being used for the treatment of morbid obesity. However, doubts still persist regarding long-term weight loss, and the 5-year results are awaited. Whether the aetiology of failed excess weight loss is the result of an inadequate sleeve or attributable to dilatation of the sleeve is not clear. In an effort to prevent gastric dilatation and increase gastric restriction to promote further weight loss in the long term, we performed a combined procedure of laparoscopic adjustable gastric banding with sleeve gastrectomy. The patient was a 39-year-old woman with a life-long history of obesity and a body mass index of 79.8 kg/m(2). The surgical technique of the laparoscopic adjustable gastric banded sleeve gastrectomy is described. There were no immediate complications, and the patient was discharged home on the third postoperative day. She is doing extremely well on clinic follow-up at 6 weeks. To the best of our knowledge, laparoscopic adjustable gastric banded sleeve gastrectomy, as a primary operation, has not been described in the literature. It is hoped that this combined procedure will be most useful in the super-super obese (body mass index > 60) patients. More patients with a long-term follow-up are necessary to provide definitive conclusions regarding long-term benefits and complications of this combined bariatric procedure.

Standardization of the fully stapled laparoscopic Roux-en-Y gastric bypass for obesity reduces early immediate postoperative morbidity and mortality: a single center study on 2606 patients.

BACKGROUND: Various techniques of laparoscopic Roux-en-Y gastric bypass have been described. We completely standardized this procedure to minimize its sometimes substantial morbidity and mortality. This study describes our experience with the standardized fully stapled laparoscopic Roux-en-Y gastric bypass (FS-LRYGB) and its influence on the 30-day morbidity and mortality. METHODS: We retrospectively analyzed 2,645 patients who underwent FS-LRYGB from May 2004 to August 2008. Operative time, hospital stay and readmission, re-operation, and 30-day morbidity/mortality rates were then calculated. The 30-day follow-up data were complete for 2,606 patients (98.5%). RESULTS: There were 539 male and 2,067 female patients. Mean age was 39.2 years (range 14-73), mean BMI 41.44 kg/m(2) (range, 23-75.5). The mean hospital stay was 3.35 days (range 2-71). Mean total operative time was 63 min (range 35-150). One patient died of pneumonia within 30 days of surgery (0.04%). One hundred and fifty one (5.8%) patients had postoperative complications as follows: gastrointestinal hemorrhage (n = 89, 3.42%), intestinal obstruction (n = 9, 0.35%), anastomotic leak (n = 5, 0.19%) and others (n = 47, 1.80%). In 66 patients, the bleeding resolved without any surgical re-intervention. One hemorrhage resulted in hypovolemic shock with subsequent renal and hepatic failure. CONCLUSION: The systematic approach and the full standardization of the FS-LRYGB procedure contribute highly to the very low mortality and the low morbidity rates in our institution. Gastrointestinal bleeding appears to be the commonest complication, but is self-limiting in the majority of cases. Our approach also significantly reduces operative time and turns the technically demanding laparoscopic Roux-en-Y gastric bypass procedure into an easy reproducible operation, effective for training.

Roux-en-Y gastric bypass as a re-do procedure for failed restricive gastric surgery.

BACKGROUND: Gastric restrictive procedures such as laparoscopic gastric banding or vertical banded gastroplasty show, at longer follow up, more and more failures and complications. This study focuses on the results of Roux-en-Y gastric bypass procedure (RYGBP) done as a re-do procedure, both after a technically failed restrictive procedure or when the restrictive procedure failed to obtain substantial weight loss. METHODS: We reviewed data concerning the postoperative complications and weight loss of 36 patients undergoing re-do surgery for failed restrictive procedures. RESULTS: Over a period of two years, 36 patients with a mean age of 40.9 years were converted to a RYGBP. Median time to conversion was 4.9 years, median follow up after conversion was 6.6 months. Early postoperative complications (less than 30 days postoperatively) were noted in 11 patients (30%). A greater number of early complications were noticed in group A (technical complications) compared to group B (insufficient weight loss) (39% vs. 22%). Late postoperative complications were seen in six patients (16%). In this relatively short follow up period we noticed a drop in body mass index (BMI) from a mean of 38.8kg/m(2) to 30.9 kg/m(2) with a mean excess body weight loss (EBWL) of 33.1% after the re-do procedure. Body mass index decreased from a mean preoperative value of 37.6kg/m(2) to 28.9 kg/m(2) in group A patients with an EBWL 36%, while group B patients had a change in BMI from 40.1kg/m(2) to 32.9 kg/m(2) with a mean EBWL of 30%. CONCLUSION: Based on the literature, we can presume that restrictive surgery for morbidly obese patients will require many reoperations in the future. The standard operation of choice is RYGBP. In our study this procedure showed a higher, but not significantly early morbidity rate when the indication for re-do surgery was a technical complication of the initial procedure.

Urine output rate and maximum volume voided in school-age children with and without nocturnal enuresis.

OBJECTIVE: To compare urine volumes voided and output rates in prepubertal children with and without monosymptomatic nocturnal enuresis (MNE), to investigate the balance between nocturnal urine output and functional bladder capacity. STUDY DESIGN: In 76 prepubertal children with MNE, all voidings were collected over 48 hours: bedwetting volume (BWV), early-morning voiding after a dry night (EMV), and other voided volumes (VV). Output rates were calculated based on volumes voided and time intervals. Data collected in 50 typical prepubertal children were used for comparison. In both populations, holding-exercise volumes (HEV) were also collected, to approximate maximum volume voided (MVV). RESULTS: Of the 15% total bedwetting events recorded with output rates more than 2 standard deviations above the normal population average, only half met the International Children's Continence Society criteria for "nocturnal polyuria." The circadian rhythm of urine output is the same in both populations; during inactivity, low rates and long filling times result in large EMV. BWVs are also produced with low rates, but have shorter filling times. MVV is small for age in MNE, but HEV for age is the same in both populations. Treating MNE with holding exercises needs to be studied prospectively. CONCLUSIONS: The cause of bedwetting might be aborted bladder filling in the circadian inactivity phase rather than nocturnal polyuria.

Do holding exercises or antimuscarinics increase maximum voided volume in monosymptomatic nocturnal enuresis? A randomized controlled trial in children.

PURPOSE: We assessed prospectively the efficacy of holding exercises and/or antimuscarinics (oxybutynin chloride and placebo) for increasing maximum voided volume in prepubertal children with monosymptomatic nocturnal enuresis. MATERIALS AND METHODS: We randomly allocated 149 children to 5 groups, namely holding exercises with placebo (group A), holding exercises with oxybutynin (group B), placebo alone (group C), oxybutynin alone (group D) and alarm treatment (controls, group E). Maximum voided volume was the greatest voided volume from a 48-hour bladder diary, and holding exercise volume was the greatest volume produced with postponement of voiding after a fluid load, once daily for 4 days. Study medication, holding exercise procedures and alarm treatment were administered for 12 weeks. RESULTS: Holding exercises combined with placebo or oxybutynin significantly increased holding exercise volume and maximum voided volume, by 25% (p <0.001) and 21% (p <0.01), respectively, in group A, and by 43% (p <0.001) and 41% (p <0.001), respectively, in group B. Medication without holding exercises (groups C and D) did not increase holding exercise volume or maximum voided volume, and in these groups oxybutynin was not significantly superior to placebo. A borderline increase in holding exercise volume did not affect maximum voided volume in group E. Monosymptomatic nocturnal enuresis response was significantly lower with all 4 holding exercise volume modulating treatments (7%) compared to alarm therapy (73%). CONCLUSIONS: In the treatment of children with monosymptomatic nocturnal enuresis maximum voided volume can be increased significantly through holding exercises, but not with oxybutynin chloride alone. Compared to controls, increasing maximum voided volume had a minimal effect on monosymptomatic nocturnal enuresis.
