RESUMO

BACKGROUND: Sleeve gastrectomy (SG) in current literature showed an increased risk of "de novo" gastroesophageal reflux disease (GERD) and increased risk for Barrett's esophagus in longer follow-up series, with a possibility of esophageal adenocarcinoma in this population. Adding primarily an anterior Dor Fundoplication to SG (Sleeve-Dor) may protect the patient for future and can potentially avoid these chronic complications for patients with obesity. METHODOLOGY: A standard SG is performed laparoscopically, and a small redundance of the fundus is maintained as a wrap, and this will be fixed to the right crura without dissection of the anatomy of the hiatus. The resulted anterior 180° Dor fundoplication is usually sufficient to relieve or to avoid reflux symptomatic. DISCUSSION: Based on our preliminary and literature experiences, the SG with anterior Dor fundoplication (Sleeve-Dor) procedure could provide favorable safety profile, satisfactory reflux control and good bariatric outcomes. The complication rate is lower compared to published for Nissen Sleeve or Sleeve-Rossetti technique, with no leaks or major complications recorded to date. Sleeve-Dor procedure may be a potential primary and standard surgery for morbidly obese patients, especially for patients with preoperative GERD symptoms without major findings at endoscopy.

RESUMO

Background: Endoscopic treatment can represent a technical challenge for several special situations, such as resecting gastric tumors with larger size or in unfavorable sites and performing endoscopic retrograde cholangiopancreatography (ERCP) after Roux-en-Y gastric bypass (RYGB). This study aims to describe an innovative and multipurpose technique, intragastric single-port surgery (IGS), which can be applied for abovementioned special situations and for assessing its safety, feasibility, and efficacy. Methods: IGS technique was performed through a 2-3 cm skin incision, where the stomach wall is exteriorized and fixed to the skin. The single-port device is inserted and intragastric access is gained for laparoscopic or endoscopic instruments. Three purposes of IGS were performed: (1). gastric intraluminal lesions resection; (2). to perform ERCP after RYGB; and (3). revision of pancreaticogastric anastomosis after pylorus-preserving pancreaticoduodenectomy. Results: IGS was performed successfully in 20 patients. Ten patients underwent gastric intraluminal lesion resection, mostly for gastric gastrointestinal stromal tumors (n = 7, 70%); all pathological specimens were with negative margin, mean operation time was 102.3 ± 43.5 minutes, and mean postoperative hospital stay was 4.6 ± 1.5 days. Nine patients underwent ERCP after RYGB, cleaning of the bile duct was successful in all patients (100%), and mean operation time and mean postoperative hospital stay were 140.6 ± 46.3 minutes and 4.4 ± 2.6 days, respectively. One patient underwent pancreaticogastric anastomosis revision. There were no mortalities in our series. Conclusions: IGS is a safe, feasible, and effective technique for gastric intraluminal lesion resection and for performing ERCP after RYGB, while it has the potential for other future applications.

RESUMO

BACKGROUND: For high-risk classified patients, patients with superobesity and in cases of contraindication to abdominal surgery, traditional bariatric surgery might lead to potential morbidity and mortality. Endoscopic sleeve gastroplasty (ESG) is a novel and effective bariatric therapy for morbidly obese patients. Our research group initially evaluated the safety, feasibility, and efficacy of ESG for high-risk, high body mass index (BMI) patients, and patients contraindicated to abdominal surgeries. METHODS: Eligible patients characterized as high-risk for bariatric surgery due to high-BMI, severe comorbidities, or impenetrable abdomen were prospectively documented. ESG was performed by using Overstich® (Apollo Endosurgery, Austin, TX, USA). Primary outcomes included technical success, post-procedure adverse events and mortality, and the change of weight and BMI. RESULTS: ESG was successfully performed for all patients (N = 24, mean age was 55.6 (± 9.2) years old, 75% male). Baseline weight and BMI were 157.9 (± 49.1) kg and 49.9 (± 14.4) kg/m2. According to Edmonton Obesity Staging System (EOSS), 8 (33.3%), 14 (58.3%), and 2 (8.3%) patients were respectively classified as EOSS 2, 3, and 4. Mean operation time was 114.7 (± 26.0) min, without intraoperative complication. Weight loss, BMI reduction, %total weight loss (%TWL), and %excess weight loss (%EWL) were 17.5 (± 14.6) kg, 5.6 (± 4.6) kg/m2, 12.2% (± 8.9%), and 29.1% (± 17.9%) at post-ESG 12-month, respectively. One (4.2%) moderate post-procedure adverse event (gastric mucosal bleeding) was observed. CONCLUSIONS: ESG can be used as a safe, feasible, and effective option for the therapy of patients with superobesity, high-risk patients, and patients contraindicated to abdominal surgery.

RESUMO

In order to implement a new bariatric surgery technique, we verify the efficacy of intragastric sleeve to reduce weight gain and subcutaneous adipose tissue (SAT). Animals were divided into two groups: G1 (single-port intragastric sleeve) and G2 (sham group). The stomach was surgically reduced by single-port intragastric sutures to fo a gastric sleeve. Animals were submitted to computer tomography (CT) before the surgical procedure and after 18 weeks. Images were analyzed and measurements of the thickness of SAT, depth and width of the longissimus dorsi muscle and the rib eye area were made. Body weight and CT measurements were analyzed using the GLM PROC. The correlation coefficients were calculated among weight, moments and measures. There was a significant difference in weight gain, in which G1 had an average of 42.803 ± 3.206 kg, lower than G2 (45.966 ± 4.767 kg). The mean values for SAT and muscle measurements differed significantly between groups, in which G1 achieved the lowest values. All variables had significant correlations and high magnitude. Intragastric sleeve surgery induced a significant decrease of SAT. The new intragastric sleeve technique is feasible, safe and effective, mainly in reducing fat deposition, making it an important alternative in bariatric surgical treatment.

RESUMO

BACKGROUND: Intragastric surgery with a single incision has been performed for several diseases, such as gastric tumors[1] and pancreatic pseudocyst[2], safety, feasibility and potential benefits of which have been reported in previous relevant studies[3]. METHODS: The video shows a 65-year-old man with upper gastrointestinal hemorrhage, preoperative abdominal CT scan and endoscopy suggested an endophytic tumor located in gastric corpus, suggesting gastrointestinal stromal tumor (GIST). Intragastric single-port surgery (IGS) was indicated. RESULTS: Under general anesthesia, patient was placed in supine position. Surgeons stood on the right side of the patient. After a 2.5cm transverse incision was made on left upper abdominal wall, gastric anterior wall was exteriorized and fixed to the skin incision. Single-port device was inserted inside the stomach after anterior gastric wall was opened. Next, laparoscope was introduced into gastric cavity and identified the location of tumor. Full thickness resection of the tumor was performed by using linear stapler, then stapler line was embedded with continuous sutures. Finally, after specimen and single-port device removal, the stomach incision was closed extracorporeally. The operation time was 112 minutes. Final pathology confirmed GIST (4.5cm) with negative margins and patient discharged after 4 days, without postoperative complications. In 1-year follow-up time, without recurrence or death. CONCLUSION: IGS is safe and effective for gastric endophytic GIST resection, which not only preserves all advantages of conventional laparoscopic operation, but also includes other benefits like obviating the need of abdominal cavity exploration, potential reduction of risk of neoplasm seeding, and offering good postoperative cosmetic result.

RESUMO

BACKGROUND: Laparoscopic conversion of Nissen Fundoplication to Roux-en-Y gastric bypass (RYGB) is a complex procedure due to increased operative time, morbidity, and length of hospital stay (LOS). In this study, a new simplified technique avoiding the total dismantling of the previous Nissen repair to construct the gastric pouch, the so-called hug technique is presented for the conversion of Nissen fundoplication to RYGB. METHODS: The present study is a prospective single-center clinical series reporting on the feasibility and safety of the "hug" technique for the creation of laparoscopic RYGB. The major innovation of this approach is the fact that the posterior part of the fundoplication wrap is left in place without further dissection or manipulation. The anterior part is stapled and remains attached to the excluded stomach. Prospective data on intraoperative and postoperative morbidity and bariatric outcomes were collected. RESULTS: A total of 44 consecutive patients with a mean body mass index (BMI) of 43.7 kg/m2 (SD = 4.0, range = 35.6-52.0) underwent the "hug" procedure between 2004 and 2015. Mean operative time was 72 min (58-105 min). Morbidity was 4.5%, with no mortality. For patients with follow-up at 3 years, the percentage of total body weight loss (%TBWL) was 32.5%; the excess weight loss (EWL) was 64.2%. CONCLUSION: In contrast to current other techniques of bariatric surgery for patients having previously undergone a Nissen fundoplication, the "hug" procedure to create an RYGB is safe and simple to perform. This technique avoids the deconstruction of the previous repair and is still maintaining anti-reflux anatomy. Nevertheless, there is a need for further studies to evaluate the long-term outcomes of the procedure.

RESUMO

During upper gastrointestinal surgery, retraction of the liver plays an essential role in the visualization and creation of an optimal surgical field. Liver retraction may be problematic, particularly in obese patients. The use of conventional liver retractors requires additional skin incision and has the potential to cause pain as well as liver injuries. The present study is the first to evaluate the performance and safety of the LiVac Sling (Livac Pty Ltd, Melbourne, Australia) trocar-free retractor system in bariatric surgery patients. In this retrospective study, data from laparoscopic primary or revisional bariatric surgeries that were performed with the LiVac Sling system and a standard retractor between May 2017 and December 2017 were collected. Demographic data, body mass index, type of surgery, number and indication of LiVac Sling system used, surgery time, and complications were analyzed. In total, 51 procedures were included. Twenty Sling devices have been used in 17 patients (13 female; 75%). The distribution of baseline characteristics was similar between the standard retractor group and LiVac Sling retractor group. In the LiVac Sling group, the number of trocars used was significantly reduced over the study period. Within 30 days postoperatively, no complications could be identified, and no device-related adverse events were reported. In this bariatric population, the use of the LiVac Sling for liver retraction was safe. No device-related adverse events were registered, and compared with standard retraction, the number of trocars used could be reduced by one.

RESUMO

BACKGROUND: In high-income countries, morbid obesity is a growing health problem that has already reached epidemic proportions. When performing a laparoscopic gastric bypass several operative methods exist. AIM: To describe the institutional experience using a knotless unidirectional barbed suture (V-Loc 180/Covidien, Mansfield, MA) to create a hand-sewn gastrojejunostomy (GJ) and jejunojejunostomy (JJ) during bariatric surgery. METHODS: Evaluation of a case series of 87 morbidly obese patients who underwent laparoscopic gastric bypass with a hand-sewn gastrojejunostomy (GJA) and jejunojejunostomy (JJA) between 01/2015 and 06/2017. The patients were divided into two groups: in group I, GJA und JJA sutures were performed using the knotless unidirectional barbed suture; in group II, GJA and JJA were sutured with resorbable multifilament thread (Vicryl® 3/0 Ethicon, Livingstone, UK). The recorded data on gender, age, BMI, ASA score, operative time, postoperative morbidity, length of hospital stay, and reoperation, were analyzed and compared. RESULTS: All procedures were completed laparoscopically with no mortality. The mean operative time was 123.23 (±30.631) in group I and 127.57 (±42.772) in group II (p<0.05). The postoperative complications did not differ significantly between the two groups. Early complications were observed for two patients (0.9%) in the barbed suture group and for one patient (0.42%) in the multifilament suture group (p<0.05). In group I two patients (0.9%) required reoperation: on the basis of jejunojejunal stenosis in one patient, and local abscess near the gastrojejunostomy, without a leakage, in the other. In group II one patient (0.42%) required reoperation due to stenosis of the GJA. The duration of hospital admission was similar for both groups: 3.36 (±0.743) days in group I vs. 3.38 (±1.058) days in group II (p<0.05). CONCLUSION: The novel anastomotic technique is a safe and effective method and can be applied to gastrojejunal anastomosis and jejunojejunal anastomosis in laparoscopic gastric bypass.

RESUMO

BACKGROUND: Patients who have undergone a Roux-en-Ygastric bypass (RYGB) and suffer from choledocholithiasis postoperatively pose a medical dilemma. Treatment of the cholestasis can be complicated because of the altered anatomy in these patients. The gastric remnant and duodenum are isolated from the pancreaticobiliary limb, making endoscopic retrograde pancreatography (ERCP) challenging and often impossible. OBJECTIVE: To describe a method for safe introduction of the endoscope into the gastric remnant through intragastric single-port surgery (IGS), thus allowing for simultaneous cholecystectomy. SETTING: Pilot clinical study. METHODS: The present study is a nonrandomized clinical series describing our preliminary results using a transgastric inserted single-port device for ERCP after RYGB. The series includes 8 patients who underwent IGS ERCP after RYGB. RESULTS: The technique was successfully applied for intraoperative ERCP through a transgastric inserted single-port device (Gelpoint Mini, Applied Medical, Rancho Santa Margarita, CA). Papilotomy was easily achieved without complications. Average operative time was 144.75 minutes. The patients recovered without complications and could be discharged after a mean of 4.38 days. CONCLUSIONS: The novel IGS technique is safe and effective and can be applied to perform ERCP in patients with RYGB anatomy. Transgastric single port ERCP was simple to perform, achieved excellent results, and allowed for endoscopic treatment and cholecystectomy to be performed in a single procedure. The technique can be indicated in patients with complicated gallstone obstruction under altered anatomy after RYGB.

RESUMO

BACKGROUND: Laparoscopic surgery changed the management of numerous surgical conditions. It was associated with many advantages over open surgery, such as decreased postoperative pain, faster recovery, shorter hospital stay and excellent cosmesis. Since two decades single-incision endoscopic surgery (SIES) was introduced to the surgical community. SIES could possibly result in even better postoperative outcomes than multi-port laparoscopic surgery, especially concerning cosmetic outcomes and pain. However, the single-incision surgical procedure is associated with quite some challenges. METHODS: An expert panel of surgeons has been selected and invited to participate in the preparation of the material for a consensus meeting on the topic SIES, which was held during the EAES congress in Frankfurt, June 16, 2017. The material presented during the consensus meeting was based on evidence identified through a systematic search of literature according to a pre-specified protocol. Three main topics with respect to SIES have been identified by the panel: (1) General, (2) Organ specific, (3) New development. Within each of these topics, subcategories have been defined. Evidence was graded according to the Oxford 2011 Levels of Evidence. Recommendations were made according to the GRADE criteria. RESULTS: In general, there is a lack of high level evidence and a lack of long-term follow-up in the field of single-incision endoscopic surgery. In selected patients, the single-incision approach seems to be safe and effective in terms of perioperative morbidity. Satisfaction with cosmesis has been established to be the main advantage of the single-incision approach. Less pain after single-incision approach compared to conventional laparoscopy seems to be considered an advantage, although it has not been consistently demonstrated across studies. CONCLUSIONS: Considering the increased direct costs (devices, instruments and operating time) of the SIES procedure and the prolonged learning curve, wider acceptance of the procedure should be supported only after demonstration of clear benefits.

RESUMO Racional : Em países de alta renda, a obesidade mórbida é um problema crescente de saúde que já atingiu proporções epidêmicas. Ao realizar um bypass gástrico laparoscópico, existem vários métodos operatórios. Objetivo: Descrever a experiência institucional utilizando uma sutura farpada unidirecional sem nós (V-Loc 180/Covidien, Mansfield, MA) para criar gastrojejunostomia (JJ) e jejunojejunostomia (JJ) costuradas à mão durante a cirurgia bariátrica. Métodos: Avaliação de uma série de casos com 87 pacientes obesos mórbidos submetidos ao bypass gástrico por videolaparoscopia com gastrojejunostomia (JJA) e jejunojejunostomia (JJA) suturados à mão entre 01/2015 e 06/2017. Os pacientes foram divididos em dois grupos; no grupo I, GJA e JJA as suturas foram realizadas com a sutura farpada unidirecional sem nós e, no grupo II, com sutura multifilamentar reabsorvível (Vicryl® 3/0 Ethicon, Livingstone, UK). Foram analisados ​​e comparados os dados registrados sobre gênero, idade, IMC, escore ASA, tempo operatório, morbidade pós-operatória, tempo de internação hospitalar e reoperação. Resultados: Todos os procedimentos foram concluídos por laparoscopia sem mortalidade. O tempo cirúrgico médio foi 123,23 (±30,631) no grupo I e 127,57 (±42,772) no grupo II (p<0,05). As complicações pós-operatórias não diferiram significativamente entre os dois grupos. Complicações precoces foram observadas em dois pacientes (0,9%) no grupo de sutura farpada e um (0,42%) no de sutura multifilamentar (p<0,05). No grupo I, dois pacientes (0,9%) necessitaram de reoperação; um devido à estenose jejunojejunal e abscesso local próximo à gastrojejunostomia, sem vazamento, no outro. No grupo II, um paciente (0,42%) necessitou de reoperação por estenose da GJA. O tempo de internação hospitalar foi semelhante nos dois grupos: 3,36 (±0,743) dias no grupo I vs. 3,38 (±1,058) dias no grupo II (p<0,05). Conclusão: A nova técnica de anastomose é método seguro e eficaz e pode ser aplicado nas anastomoses gastrojejunal e jejunojejunal no bypass gástrico laparoscópico.

RESUMO

Developing a less invasive, practical and cost-effective operative technique for obesity treatment represents a pressing need for our society. In this way, intragastric single port sleeve by endoplication was tested in six pigs during 18 weeks. Celiotomy was performed with animal placed in dorsal decubitus position. Single port gastrostomy was performed and double tobacco pouch sutures were made in fundic region, making a gastric sleeve. At the end, stomach layers and skin were closed in a conventional manner. Means and the standard deviations of surgical time were calculated. The procedure was simple and all animals survived; there were no significant blood loss and no intra and postoperative complications. The procedure was fast (67.4 minutes). The technique has the advantage of not requiring the use of mechanical sutures, making it less costly. The innovation of this procedure was the use of a single port gastrostomy device to perform an intraluminal sleeve. What made this technique less invasive were the use of a single port, nonmanipulation of the stomach intra-abdominally, ease of execution and no need of pneumoperitoneum. The new technique is acceptable and has reproducible viability, had a short procedure time without intra and postoperative complications.

RESUMO

BACKGROUND: Minimally invasive thyroid and parathyroid resections are rarely performed. Promising new endoscopic transoral approaches to the anterior neck (transoral endoscopic thyroidectomy vestibular approach [TOETVA]) have been described with good results and few complications. This study evaluates a new device to allow the safe entrance of trocars in the subplatysmal space for TOETVA in a cadaver model. METHODS: The technique was performed in 4 unilateral thyroidectomies in female cadavers. The technical steps consisted of a 10-mm incision made at the center of the oral vestibule followed by subplatysmal hydrodissection. The blunt dissector is a metallic stick with an olive at the end and promotes progressive gain in subplatysmal space enlarging the operative field. The instrument was inserted creating a space below the platysma to the anterior neck and the strap muscles. Three trocars were inserted in the vestibular area. The dissection begins by cutting the linea alba cervicalis. The isthmus was dissected and transected. Anatomical structures as the superior thyroid artery, parathyroid glands, and the recurrent laryngeal nerve could be safely identified with magnified vision. RESULTS: Optimal operative field due to subplatysmal dissection by the device allowed for exposition of thyroid and parathyroid glands in all cases. Unilateral thyroidectomy was performed in a mean of 54 minutes with excellent aesthetic results. CONCLUSIONS: The new device is a promising feature to allow safe transoral thyroid surgery in a cadaver model. Further studies in clinical series are needed to evaluate the broad application of the device.

RESUMO

PURPOSE: To perform technically the laparoscopic sleeve gastrectomy (LSG) using a unique Intragastric Single Port (IGSG) in animal swine model, evidencing an effective and safe procedure, optimizing the conventional technique. METHODS: IGSG was performed in 4 minipigs, using a percutaneous intragastric single port located in the pre-pyloric region. The gastric stapling of the greater curvature started from the pre-pyloric region towards the angle of His by Endo GIA™ system and the specimen was removed through the single port. In the postoperative day 30, the animals were sacrificed and submitted to autopsy. RESULTS: All procedures were performed without conversion, and all survived 30 days. The mean operative time was 42 min. During the perioperative period no complications were observed during invagination and stapling. No postoperative complications occurred. Post-mortem examination showed no leaks or infectious complications. CONCLUSION: Intragastric Single Port is a feasible procedure that may be a suitable alternative technique of sleeve gastrectomy for the treatment of morbid obesity.

RESUMO

BACKGROUND: Ostomy reversals remain at high risk for surgical complications. Indeed, surgical-side infections due to bacterial contamination of the stoma lead to revision surgery and prolonged hospital stay. AIM: To describe the novel vulkan technique of ostomy reversal that aims to reduce operative times, surgical complications, and readmission rates. METHODS: Ostomy closure was performed using the vulkan technique in all patients. This technique consists of external intestinal closure, circular skin incision and adhesiolysis, re-anastomosis, and closure of the subcutaneous tissue in three layers, while leaving a small secondary wound through which exudative fluid can be drained. The medical records of enterostomy patients were retrospectively reviewed from our hospital database. RESULTS: The vulkan technique was successfully performed in 35 patients mainly by resident surgeons with <5 years of experience (n=22; 62.8%). The ileostomy and colostomy closure times were 53 min (interquartile range [IQR], 41-68 min; n=22) and 136 min (IQR: 88-188 min; n=13; p<0.001), respectively. The median hospital stay was seven days (IQR: 5-14.5 days); the length of hospital stay did not differ between ileostomy and colostomy groups. Major surgical complications occurred only in patients who underwent colostomy closure following the Hartmann procedure (n=2); grade≥IIIb according Clavien-Dindo classification. CONCLUSION: The vulkan technique was successfully applied in all patients with very low rates of surgical-site infections. Off note, residents with limited surgical experience mainly performed the procedure while operating time was less than one hour.

RESUMO

BACKGROUND: Potential benefits of laparoscopic liver resections (LLRs) over open liver resections (OLRs) such as the clinical outcome and health-related quality of life (HRQoL) have not convincingly been investigated, yet. PATIENTS AND METHODS: All patients who had undergone LLR and OLR at our department between 1 June 2014 and 10 October 2016 were identified. HRQoL was assessed using the short form 36 (SF-36). All patients who returned the surveys were then retrospectively analysed with regards to the perioperative outcome. RESULTS: We received 66 eligible questionnaires (50%). The number of major liver resections did not significantly differ between both groups (LLR: 11 [33%], OLR: 16 [48%], P = 0.211).The proportion of patients with two or more co-morbidities (P = 0.044) and liver cirrhosis (P = 0.016), respectively, was significantly higher in the LLR group, when compared to the OLR group (LLR: 11 [33%] vs. 3 of 33 patients [9%], P = 0.016). HRQoL scores were good with no significant differences between both groups. Among these patients, there were significantly more pulmonary complications in the OLR group, and length of hospital stay was longer when compared to the LLR group. CONCLUSIONS: Laparoscopic liver surgery can be performed safely even in multimorbid elderly patients resulting in high HRQoL scores.

RESUMO

This article focuses on the anatomy, literature, and our own experiences in an effort to assist in the decision-making process of choosing between an umbilical or vaginal port. Umbilical access is more familiar to general surgeons; it is thicker than the transvaginal entry, and has more nerve endings and sensory innervations. This combination increases tissue damage and pain in the umbilical port site. The vaginal route requires prophylactic antibiotics, a Foley catheter, and a period of postoperative sexual abstinence. Removal of large specimens is a challenge in traditional laparoscopy. Recently, there has been increased interest in going beyond traditional laparoscopy by using the navel in single-incision and port-reduction techniques. The benefits for removal of surgical specimens by colpotomy are not new. There is increasing interest in techniques that use vaginotomy in multifunctional ways, as described under the names of culdolaparoscopy, minilaparoscopy-assisted natural orifice surgery, and natural orifice transluminal endoscopic surgery. Both the navel and the transvaginal accesses are safe and convenient to use in the hands of experienced laparoscopic surgeons. The umbilical site has been successfully used in laparoscopy as an entry and extraction port. Vaginal entry and extraction is associated with a lower risk of incisional hernias, less postoperative pain, and excellent cosmetic results.
