STAPLED FASCIAL CLOSURE VS. CONTINUOUS HAND-SEWN SUTURE: EXPERIMENTAL STUDY OF THE ABDOMINAL WALL ON PORCINE MODEL AND HUMAN CADAVER.

BACKGROUND: One of the primary complications associated with large incisions in abdominal surgery is the increased risk of fascial closure rupture and incisional hernia development. The choice of the fascial closure method and closing with minimal tension and trauma is crucial for optimal results, emphasizing the importance of uniform pressure along the suture line to withstand intra-abdominal pressure. AIMS: To evaluate the resistance to pressure and tension of stapled and sutured hand-sewn fascial closure in the abdominal wall. METHODS: Nine abdominal wall flaps from human cadavers and 12 pigs were used for the experimentation. An abdominal defect was induced after the resection of the abdominal wall and the creation of a flap in the cadaveric model and after performing a midline incision in the porcine models. The models were randomized into three groups. Group 1 was treated with a one-layer hand-sewn small bite suture, Group 2 was treated with a two-layer hand-sewn small bite suture, and Group 3 was treated with a two-layer stapled closure. Tension measurements were assessed in cadaveric models, and intra-abdominal pressure was measured in porcine models. RESULTS: In the human cadaveric model, the median threshold for fascial rupture was 300N (300-350) in Group 1, 400N (350-500) in Group 2, and 350N (300-380) in Group 3. Statistical comparisons revealed non-significant differences between Group 1 and Group 2 (p=0.072, p>0.05), Group 1 and Group 3 (p=0.346, p>0.05), and Group 2 and Group 3 (p=0.184, p>0.05). For porcine subjects, Group 1 showed a median pressure of 80 mmHg (85-105), Group 2 had a median of 92.5 mmHg (65-95), and Group 3 had a median of 102.5 mmHg (80-135). Statistical comparisons indicated non-significant differences between Group 1 and Group 2 (p=0.243, p>0.05), Group 1 and Group 3 (p=0.468, p>0.05), and Group 2 and Group 3 (p=0.083, p>0.05). CONCLUSIONS: Stapled and conventional suturing resist similar pressure and tension thresholds.

ROBOTIC-ASSISTED VERSUS LAPAROSCOPIC INCISIONAL HERNIA REPAIR: DIFFERENCES IN DIRECT COSTS FROM A BRAZILIAN PUBLIC INSTITUTE PERSPECTIVE.

BACKGROUND: Robotic-assisted surgery research has grown dramatically in the past two decades and the advantages over traditional videolaparoscopy have been extensively debated. For hernias, the robotic system can increase intraoperative strategies, especially in complex hernias or incisional hernias. AIMS: This study aimed to compare the direct cost differences between robotic and laparoscopic hernia repair and determine each source of expenditure that may be related to the increased costs in a robotic program from the perspective of a Brazilian public institution. METHODS: This study investigated the differences in direct costs from the data generated from a trial protocol (ReBEC: RBR-5s6mnrf). Patients with incisional hernia were randomly assigned to receive laparoscopic ventral incisional hernia repair (LVIHR) or robotic ventral incisional hernia repair (RVIHR). The direct medical costs of hernia treatment were described in the Brazilian currency (R$). RESULTS: A total of 19 patients submitted to LVIHR were compared with 18 submitted to RVIHR. The amount spent on operation room time (RVIHR: 2,447.91±644.79; LVIHR: 1,989.67±763.00; p=0.030), inhaled medical gases in operating room (RVIHR: 270.57±211.51; LVIHR: 84.55±252.34; p=0.023), human resources in operating room (RVIHR: 3,164.43±894.97; LVIHR: 2,120.16±663.78; p<0.001), material resources (RVIHR: 3,204.32±351.55; LVIHR: 736.51±972.32; p<0.001), and medications (RVIHR: 823.40±175.47; LVIHR: 288.50±352.55; p<0.001) for RVIHR was higher than that for LVIHR, implying a higher total cost to RVIHR (RVIHR: 14,712.24±3,520.82; LVIHR: 10,295.95±3,453.59; p<0.001). No significant difference was noted in costs related to the hospital stay, human resources in intensive care unit and ward, diagnostic tests, and meshes. CONCLUSION: Robotic system adds a significant overall cost to traditional laparoscopic hernia repair. The cost of the medical and robotic devices and longer operative times are the main factors driving the difference in costs.

Robotic-assisted compared with laparoscopic incisional hernia repair following oncologic surgery: short- and long-term outcomes of a randomized controlled trial.

BACKGROUND: Patients with abdominal site cancer are at risk for incisional hernia after open surgery. This study aimed to compare the short- and long-term outcomes of robotic-assisted (RVIHR) with the laparoscopic incisional hernia repair (LVIHR) in an oncologic institute. METHODS: This is a single-blinded randomized controlled pilot trial. Patients were randomized into two groups: RVIHR and LVIHR. RESULTS: Groups have similar baseline characteristics (LVIHR: N = 19; RVIHR: N = 18). No difference was noted in the length of hospital stay (RVIHR: 3.67 ± 1.78 days; LVIHR: 3.95 ± 2.66 days) and postoperative complications (16.7 versus 10.5%; p = 0.94). The mean operating time for RVIHR was significantly longer than LVIHR (RVIHR was 355.6 versus 293.5 min for LVIHR; p = 0.04). Recurrence was seen in three patients in LVIHR and two in RVIHR at 24-month follow-up, with no significant difference. (p > 0.99). CONCLUSION: Laparoscopic and robotic-assisted incisional hernia repair show similar short- and long-term outcomes for cancer patients.

Short-Term Surgical Outcomes of Robotic Gastrectomy Compared to Open Gastrectomy for Patients with Gastric Cancer: a Randomized Trial.

BACKGROUND: Robotic gastrectomy (RG) has been shown to be a safe and feasible method in gastric cancer (GC) treatment. However, most studies are in Eastern cohorts and there is great interest in knowing whether the method can be used routinely, especially in the West. OBJECTIVES: The aim of this study was to compare the short-term surgical outcomes of D2-gastrectomy by RG versus open gastrectomy (OG). METHODS: Single-institution, open-label, non-inferiority, randomized clinical trial performed between 2015 and 2020. GC patients were randomized (1:1 allocation) to surgical treatment by RG or OG. Da Vinci Si platform was used. INCLUSION CRITERIA: gastric adenocarcinoma, stage cT2-4 cN0-1, potentially curative surgery, age 18-80 years, and ECOG performance status 0-1. EXCLUSION CRITERIA: emergency surgery and previous gastric or major abdominal surgery. Primary endpoint was short-term surgical outcomes. The study is registered at clinicaltrials.gov (NCT02292914). RESULTS: Of 65 randomized patients, 5 were excluded (3 palliatives, 1 obstruction and emergency surgery, and 1 for material shortage). Consequently, 31 and 29 patients were included for final analysis in the OG and RG groups, respectively. No differences were observed between groups regarding age, sex, BMI, comorbidities, ASA, and frequency of total gastrectomy. RG had similar mean number of harvested lymph nodes (p = 0.805), longer surgical time (p < 0.001), and less bleeding (p < 0.001) compared to OG. Postoperative complications, length of hospital stay, and readmissions in 30 days were equivalent between OG and RG. CONCLUSIONS: RG reduces operative bleeding by more than 50%. The short-term outcomes were non-inferior to OG, although surgical time was longer in RG.

Rare complication of ventriculoperitoneal shunt: Catheter protrusion to subcutaneous tissue - Case report.

BACKGROUND: Ventriculoperitoneal (VP) shunt is a day-to-day procedure performed by a neurosurgeon. The most frequent associated complications are obstructive and infectious. Although rare, there are well-reported complications related to the poor positioning of the distal catheter, with perforation of organs and tissues. Still rarer are the complications related to the migration of this catheter. CASE DESCRIPTION: We describe an atypical case of VP shunt postoperative by normal pressure hydrocephalus. After well-documented proper positioning of the distal catheter into the intraperitoneal cavity, it protruded into the subcutaneous space. Even on a new documented satisfactory abdominal tomography, this catheter migrated back again to the subcutaneous tissue. CONCLUSION: We did not find plausible explanation for this rare event.

Tratamento de hérnias da linha média do abdome com uso de grampeador endoscópico para fechamento da linha média / Treatment of mid-line abdominal wall hernias with the use of endo-stapler for mid-line closure

INTRODUÇÃO: A cirurgia minimamente invasiva modificou a maneira de analisar e dissecar os tecidos nos procedimentos cirúrgicos. No entanto, a vantagem deste método é limitada na parede abdominal, devido à falta de desenvolvimento de tecnologias e movimentos articulados para seu emprego nesta região, exigindo a necessidade de investimentos e de tempo para a solidificação. Esta abordagem para reparo operatório da parede abdominal é baseada nos princípios Rives-Stoppa. TÉCNICA: Com o paciente em decúbito dorsal, uma pequena incisão supra-púbica é feita e o espaço pré-peritoneal é alcançado e insuflado. Após os trocárteres serem colocados, o saco peritoneal é dissecado e a cavidade abdominal é atingida acima da linha arqueada. As bainhas posteriores do músculo reto do abdome são liberadas e um grampeador linear é colocado em ambos os lados e acionado, restituindo a linha média e criando um espaço retromuscular, onde a tela é colocada e fixada. CONCLUSÃO: O método é viável, fácil de realizar e reprodutível, economizando tempo e com resultado funcional satisfatório.

INTRODUCTION: Minimally invasive videosurgery has modified anatomy dissection of diseases that are treated operatively. However, the benefit of this method has been delayed due to the lack of development of technologies and articulated movements for the abdominal wall, demanding the need for investments and time for solidification. This approach to repair the abdominal wall is based on the Rives-Stoppa principles. TECHNIQUE: With the patient in supine position, a small supra pubic incision is done and the pre-peritoneal space is achieved and inflated. After the trocars are placed, the peritoneal sac is dissected and the abdominal cavity is entered, above the arcuate line. The posterior rectus sheath is liberated and a linear stapler is placed in both sides and fired, creating a midline and a retromuscular space, where the mesh is placed and fixed. CONCLUSION: The method is feasible, easy to perform, reproducible, saves time and with a good functional result.

Robotic abdominal surgery: a Brazilian initial experience.

BACKGROUND: Robotic brought to laparoscopy the enrichment of movements, the easy to perform maneuvers and procedures, visualization in three dimensions, and ergonomics for the surgeon. AIM: To describe Brazilian experience with robotically-assisted abdominal surgery. METHODS: From July 2008 to April 2010, patients were admitted for abdominal surgery and agreed to being operated with the help of the robot by a trained medical staff. All patients were operated by the same surgical robotic approach. Time required for complete surgery, and console time, were recorded. RESULTS: Forty-four patients were operated, most for hernial hiatal correction or bariatric surgery. All patients, except one, were discharged in the day after surgery. The only complication was a fistula due to a videolaparoscopic clamping procedure during bariatric surgery. There was no hemorrhage. No re-operation was necessary, neither conversion to laparoscopic or open surgery. Mean surgery time for the whole sample was 249.7 minutes (4.1 hours) and console time was 153.4 minutes (2.5 hours). Patients' blood lost was minimal. CONCLUSIONS: Robotically assisted abdominal surgery is safe for the patients, with reduced bleeding and acceptable surgical time, and also ergonomic for the surgeons.

No re-operation was necessary, neither conversion to laparoscopic or open surgery. Mean surgery time for the whole sample was 249.7 minutes (4.1 hours) and console time was 153.4 minutes (2.5 hours). Patients' blood lost was minimal. CONCLUSIONS: Robotically assisted abdominal surgery is safe for the patients, with reduced bleeding and acceptable surgical time, and also ergonomic for the surgeons.

Treatment of mid-line abdominal wall hernias with the use of endo-stapler for mid-line closure.

INTRODUCTION: Minimally invasive videosurgery has modified anatomy dissection of diseases that are treated operatively. However, the benefit of this method has been delayed due to the lack of development of technologies and articulated movements for the abdominal wall, demanding the need for investments and time for solidification. This approach to repair the abdominal wall is based on the Rives-Stoppa principles. TECHNIQUE: With the patient in supine position, a small supra pubic incision is done and the pre-peritoneal space is achieved and inflated. After the trocars are placed, the peritoneal sac is dissected and the abdominal cavity is entered, above the arcuate line. The posterior rectus sheath is liberated and a linear stapler is placed in both sides and fired, creating a midline and a retromuscular space, where the mesh is placed and fixed. CONCLUSION: The method is feasible, easy to perform, reproducible, saves time and with a good functional result.

Procedimento de Rives/Stoppa modificado robô-assistido para correção de hernias ventrais da linha média / Modified robot assisted Rives/Stoppa videosurgery for midline ventral hernia repair

RACIONAL: Os defeitos da linha média podem ser congênitos ou adquiridos. Os procedimentos convencionais para correção desse defeito geralmente envolvem grandes incisões, com grandes descolamentos de pele e tecido celular subcutâneo. O uso da videocirurgia para a correção desses defeitos, ainda é controverso. OBJETIVOS: Realizar descrição inédita na literatura, mostrando a experiência inicial do uso da robótica nas reconstruções de linha média, associando a cirurgia minimamente invasiva à técnicas consagradas como Rives/Stoppa e separação de componentes. MÉTODOS: Foram operados cinco pacientes no mesmo hospital, pela mesma equipe, usando o sistema robótico da Vinci S. RESULTADOS: Foram três mulheres e dois homens, sem mortalidade na amostra. Duas pacientes foram reoperadas com hérnia pelo tunel entre os músculos retos do abdomen e aponeurose posterior, com fechamento dos mesmos na reoperação. CONCLUSÕES: O procedimento robótico para reconstrução da linha média mostrou-se factível e esteticamente aceitável. Tem a vantagem de seguir os princípios tradicionais aventados para a parede abdominal através de via minimamente invasiva.

BACKGROUND:The weakness of the linea alba can be caused by congenital and aquired factors. The conventional procedure to correct these imperfections generally involve large incisions with big detachments of the skin and subcutaneous tissue. The use of videosurgery for the repair of these weaknesses is still controversy. AIM: To describe a new procedure using robotics in the repair of the linea alba, associating minimally invasive tecniques by Rives/Stoppa and component separation tecniques. METHODS: Five patients undergone surgery in the same hospital, the same operating team and using the Da Vinci S. robotics equipment. RESULTS: Three women and two men undergone surgery, with no mortality. Two of these patients were re-operated due a recurrent hernia between muscle and posterior sheath that was closed in the re-access. CONCLUSIONS: The robotic procedure in the reconstruction of the linea alba showed itself feasible and aesthetically acceptable. Also, in advantage, the procedure follows the traditional principals reputable by experts of the abdominal wall trough minimally invasive surgery.

Brazilian experience in obesity surgery robot-assisted.

BACKGROUND: Minimally invasive techniques were associated with bariatric surgery, leading to a decrease in aggression to the organs and systems. Robotic surgery is a new possibility within the concept of minimal invasion. AIM: To evaluate the initial experience of robotic surgery for obesity. METHODS: Twenty seven patients were operated in the same hospital, by the same team with the same surgical system, Da Vinci S. RESULTS: Were performed six gastric band placement , five sleeve gastrectomies and 16 gastric bypasses. There was one major complication and no death in this series. CONCLUSIONS: The robotic surgery for obesity surgery was safe during the initial experience.
