PURPOSE: A surgical gastrostomy is mandatory in cases where a PEG is not feasible. Various minimally invasive techniques have been described, but many involve unusable materials in small children and/or have risk of disunion. We describe a technique for true Stamm gastrostomy performed by laparoscopy (LSG) with a purse string suture and four points of attachment onto the wall. METHOD: We reviewed 20 children who underwent an LSG from 2010 to 2013. After incision of the skin at the location planned for the gastrostomy, using three 3-5mm ports the stomach is fixed to the wall by three suspension stitches, which are entered and then emerged subcutaneously. A fourth stitch of attachment is used to make an award on the stomach and tie around the gastrostomy tube. RESULTS: Mean age was 4.2years, with 70% aged <2years. All children were malnourished, most often severely. All but two underwent a concomitant fundoplication. Feeding through the gastrostomy started on D0 or D1. Total feeding by gastrostomy was achieved in a mean duration of 2.9day. Mean hospital stay was 4.5days. There was no perioperative complication. Mean follow-up was 14months. Once, the balloon was accidently deflated and reinflated in the wall leading to its necrosis. Five peristomial granulomas were noticed. It was always possible to replace the tube by a gastrostomy device at least 6weeks after surgery. CONCLUSION: This new technique for true Stamm gastrostomy by laparoscopy reproduces exactly the one done by laparotomy, without special equipment. It can be made since the neonatal period, in all the circumstances when a laparoscopy is possible.

BACKGROUND: Roux-en-Y gastric bypass (RYGBP), one of the commonest performed bariatric procedures, remains a technically challenging operation associated with significant morbidity in high-risk patients. This study was conducted in order to identify predictors of complications after laparoscopic RYGBP. METHODS: Our prospectively established database has been assessed to review 30-day and in-hospital complications graded according to a validated scoring system (Clavien-Dindo) and separated into minor (Clavien-Dindo I-IIIa) and major (Clavien-Dindo IIIb-IV) complications. Patient- and procedure-related factors were analyzed using univariate analysis. Significant factors associated with morbidity were introduced into a multivariate analysis to identify independent predictors. RESULTS: Between 1999 and 2012, 1573 patients underwent laparoscopic RYGBP, 374 male and 1199 female. Mean age was 41 years, and mean body mass index (BMI) was 44.5 kg/m(2). One hundred fifty-nine procedures were reoperations. One hundred fifty (9.5 %) patients developed at least one complication, and 43 (2.7 %) had major complications, leading to death in one case (0.06 %). Risk factors for morbidity were male gender (p = 0.006) and overall experience of the team (p < 0.0001). Prolonged 3-day antibiotic therapy was associated with significantly reduced overall (p < 0.0001) and major (p = 0.005) complication rates. Major complications were associated with smoking (p = 0.016). CONCLUSIONS: The most significant individual risk factors for early complications after RYGBP are male gender, limited surgical experience, and single dose of antibiotics. RYGBP should be performed by experienced teams. Smoking should be discontinued before surgery. Prolonged antibiotic therapy could be considered, especially if a circular stapled gastrojejunostomy is performed with the anvil introduced transorally.

The prevalence of obesity is increasing even in older patients. Bariatric surgery is often considered more risky in this group, and not necessarily associated with the same benefits as in younger patients. In France, guidelines recommend to assess indication for surgery based on comorbidities and physiological age.

BACKGROUND: The use of a robotic surgical system is claimed to allow precise traction and counter-traction, especially in a narrow pelvis. Whether this translates to improvement of the quality of the resected specimen is not yet clear. The aim of the study was to compare the quality of the TME and the short-term oncological outcome between robotic and laparoscopic rectal cancer resections. METHODS: 20 consecutive robotic TME performed in a single institution for rectal cancer (Rob group) were matched 1:2 to 40 laparoscopic resections (Lap group) for gender, body mass index (BMI), and distance from anal verge on rigid proctoscopy. The quality of TME was assessed by 2 blinded and independent pathologists and reported according to international standardized guidelines. RESULTS: Both samples were well matched for gender, BMI (median 25.9 vs. 24.2 kg/m(2), p = 0.24), and level of the tumor (4.1 vs. 4.8 cm, p = 0.20). The quality of the TME was better in the Robotic group (complete TME: 95 vs. 55 %; p = 0.0003, nearly complete TME 5 vs. 37 %; p = 0.04, incomplete TME 0 vs. 8 %, p = 0.09). A trend for lower positive circumferential margin was observed in the Robotic group (10 vs. 25 %, p = 0.1). CONCLUSIONS: These results suggest that robotic-assisted surgery improves the quality of TME for rectal cancer. Whether this translates to better oncological outcome needs to be further investigated.

The authors present the four-arm single docking full robotic surgery to treat low rectal cancer. The eight main operative steps are: 1- patient positioning; 2- trocars set-up and robot docking; 3- sigmoid colon, left colon and splenic flexure mobilization (lateral-to-medial approach); 4-Inferior mesenteric artery and vein ligation (medial-to-lateral approach); 5- total mesorectum excision and preservation of hypogastric and pelvic autonomic nerves (sacral dissection, lateral dissection, pelvic dissection); 6- division of the rectum using an endo roticulator stapler for the laparoscopic performance of a double-stapled coloanal anastomosis (type I tumor); 7- intersphincteric resection, extraction of the specimen through the anus and lateral-to-end hand sewn coloanal anastomosis (type II tumor); 8- cylindric abdominoperineal resection, with transabdominal section of the levator muscles (type IV tumor). The techniques employed were safe and have presented low rates of complication and no mortality.

The gastrointestinal stromal tumor (GIST) is a rare mesenchymal tumor. One should pay special attention when the GIST comes in obese patients during surgery. The laparoscopic resections with standard techniques, such as gastric bypass, have been described with good results. However, GIST resection associated sleeve gastrectomy for the treatment of obesity is rare, but can be done safely, depending on the location of the tumor.

The authors describe a surgical technique which allows, without increasing costs, to perform laparoscopic cholecystectomy with a single incision, without using specific materials and with better surgical ergonomics. The technique consists of a longitudinal umbilical incision, navel detachment, use of a permanent 10mm trocar and two clamps directly and bilaterally through the aponeurosis without the use of 5mm trocars, transcutaneous gallbladder repair with straight needle cotton suture, ligation with unabsorbable suture and umbilical incision for the specimen extraction. The presented technique enables the procedure with conventional and permanent materials, improving surgical ergonomics, with safety and aesthetic advantages.

Objective: to analyze the differences in mortality rates, length of hospital stay, time of surgery and the conversion rate between elective open cholecystectomies (OC) and laparoscopic ones (LC) in elderly patients. Methods : we evaluated medical records of patients 65 years of age or older undergoing open or laparoscopic cholecystectomy at the Hospital Regional de Mato Grosso do Sul between January 2008 and December 2011. We excluded individuals operated in non-elective scenarios or who underwent intraoperative cholangiography. Results : we studied 113 patients, of whom 38.1% were submitted to the OC and 61.9%, to LC. Women accounted for 69% of patients and men, for 31%. The conversion rate was 2.9%. The mean age and duration of the procudure was 70.1 and 84 minutes, respectively, with no significant difference between OC and LC. Patients undergoing LC had shorter hospital stays (2.01 versus 2.95 days, p=0.0001). We identified operative complications in sixpatients (14%) after OC and in nine (12%) after LC, with no statistical difference. Conclusion : there was no difference in morbidity and mortality when comparing OC with LC. The laparoscopic approach led to shorter hospital stay. Operative time did not differ between the two access routes. The conversion rate was similar to other studies.

Background: Controversy exists concerning indications and outcomes of major bariatric surgery procedures. Massive weight loss after bariatric surgery leads to excess skin with functional and aesthetic impairments. The aim of this study was to investigate the major bariatric surgery procedures and their outcomes in two specific subgroups of morbidly obese patients, ≥55-year-olds and the superobese. Further aims were to evaluate whether the preoperative weight loss correlates with laparoscopic gastric bypass complications. The prevalence and impact of excess skin and the desire for body contouring after bariatric surgery were also studied. Patients and Methods: Data from patients who underwent Laparoscopic Adjustable Gastric Banding (LAGB) and Laparoscopic Roux-en-Y Gastric Bypass (LRYGB) at Vaasa Central Hospital were collected and postoperative outcomes were evaluated according to the BMI, age and preoperative weight loss. Patients who had undergone bariatric surgery procedures were asked to complete a questionnaire to estimate any impairment due to redundant skin and to analyse each patient’s desire for body contouring by area. Results: No significant difference was found in operative time, hospital stay, or overall early postoperative morbidity between LAGB and LRYGB. Mean excess weight loss percents (EWL%) at 6 and 12 months after LRYGB were significantly higher. A significant difference was found in operative time favouring patients <55 years. Intraoperative complications were significantly more frequent in the group aged >55 years. No significant difference was detected in overall postoperative morbidity rates. A significant difference was found in operative time and hospital stay favouring all patients who lost weight preoperatively. Most patients reported problems with redundant skin, especially on the abdomen, upper arms and rear/buttocks, which impaired daily physical activity in half of them. Excess skin was significantly associated with female gender, weight loss and ΔBMI. Patients with a WL >20 kg, ΔBMI ≥10 kg/m2 and an EWL % > 50 showed a significantly surplus skin discomfort (p < 0.001). Most patients desired body contouring surgery, with high or very high desire for waist/abdomen (62.2%), upper arm (37.6%), chest/breast (28.3%), and rear/buttock (35.6%) contouring. Conclusions: LRYGB is effective and safe in superobese (BMI >50) and elderly (>55 years) patients. A preoperative weight loss >5% is recommended to improve the outcomes and reduce complications. A WL >20 kg, ΔBMI ≥10 kg/m2 and an EWL % > 50 are associated with a higher functional discomfort due to redundant skin and to a stronger desire for body contouring plastic surgery.

PURPOSE: To analyze the behavior of cardiopulmonary function in postoperative of laparoscopic Nissen fundoplication.METHODS: Thirty-two patients, 13 males (41%) and 19 females (59%), were evaluated. Their age ranged from 25 to 67 years, with a mean of 44.4 +/- 10.9. Pulmonary volumes, respiratory pressures and exercise tests were performed in the preoperative period (PRE) and in the first (PO1), second (PO2), fifth (PO5) and thirtieth (PO30) postoperative periods.RESULTS: Thirty-two patients were evaluated, of whom 59% were females. Mean age was 44.4 +/- 10.9 years. Lung volumes had significant decrease at PO1 and PO2 and were similar to PRE values at PO5. Respiratory pressures were altered only at PO1. The distance covered in the 6-minute walk test had significant reduction until PO2, and climbing time in the stair-climbing test significantly increased at PO2.CONCLUSION: Patients submitted to LNF surgery have decreased cardiorespiratory function in the early postoperative period; however, they soon return to preoperative conditions.

Background: Limitations of endovascular thoracic aneurym treatment include small, tortuous, or severely calcified iliac Back, arteries. We present our experience with a total laparoscopic access to deploy thoracic endografts.Methods. A total laparoscopic left retrocolic approach was used in all cases. A Dacron conduit was laparoscopically sutured to either the iliac artery or to the aorta directly. The endograft was inserted through this conduit. After graft deployment, the Dacron prosthesis was tunneled to the groin and anastomosed with the femoral artery.Results. The laparoscopic procedure could successfully be performed in 11 patients. In six cases, the aorta was used as all access and in five patients, the iliac arteries were preferred. In one of these cases, the right iliac artery, was used for deployment of the endograft. After successful aorto- or ileo-femoral bypass grafting, all patients had an improvement of their ankle brachial index postoperatively. The mean operative time was almost four hours, including laparoscopy, laparoscopic anastomosis, endograft deployment, and femoral artery anastomosis or profundaplasty.Conclusion: Totally laparoscopic assisted graft implantation in aorta or iliac arteries provides a safe and effective access for the endovascular delivery system. However, further evaluation and long follow-up are necessary to ensure the potential advantages of this technique. It is a less invasive option to overcome access-related problems with thoracic endograft deployment, giving the patient the advantage of a totally minimal invasive procedure.

Purpose: To present our series of patients who underwent laparoscopic correction of iatrogenic lesions and a review of the literature.Patients and Methods: We evaluated 23 patients who underwent laparoscopic correction of iatrogenic lesions. Thirteen patients had open surgery, 6 had an endoscopic procedure, and 4 had a laparoscopic approach as the first surgical procedure. Vesicovaginal fistulas (VVF) developed in seven patients after open abdominal hysterectomies, and 1 patient presented with a VVF after ureterolithotripsy. A urethral cutaneous fistula developed in one patient after a laparoscopic resection of endometriosis nodules, and 1 patient presented with a ureterovaginal fistula after a perineoplasty. Three patients presented with encrusted ureteral stents after ureterolithotripsy. Ureteral stenosis developed in seven patients: three after open abdominal surgery, three after ureteroscopy, and one after pyeloplasty. One patient had a ureteral injury during laparoscopic partial nephrectomy, and two patients had bowel injuries after a tension-free vaginal tape procedure and a laparoscopic radical prostatectomy.Results: All patients underwent laparoscopic correction of the iatrogenic injuries. One patient had an early recurrence of a VVF, and one patient had a recurrence of a ureteral stenosis. There was one conversion to open surgery because of technical difficulties and one major bleeding event that necessitated blood transfusion. A lower limb compartmental syndrome developed in one patient.Conclusion: Despite the small number of patients and different types of surgeries performed, laparoscopic management of iatrogenic lesions seems to be feasible and safe in experienced hands. Its precise role in the management of this stressful condition still needs to be determined.
