Single-port for laparoscopic gastric resection with a novel platform / Ressecção gástrica laparoscópica com single-port utilizando uma nova plataforma

INTRODUCTION: Laparoscopic gastrointestinal resections using single-port are possible, but triangulation problems and the need of articulated instruments difficult the procedures. AIM: To present a surgical alternative using single-port laparoscopic device on gastric resection. TECHNIQUE: The patient is placed in a supine and reverse Trendelenburg position with surgeon between patient's legs. First assistant was on the right side of the patient with the monitor placed on the patient's cranial side. With the patient under general anesthesia, a transumbilical 3 cm skin incision is performed. A single-incision advanced access platform with gelatin cap, self-retaining sleeve and wound protector is introduced through this incision. Three 5-12 mm operating ports were introduced through the single-port device. Due to the gel cap and sleeves, no articulated instruments are necessary. CO2 pneumoperitoneum is established at 12 mmHg. A rigid 30 degree 10 mm laparoscope is introduced. Operation begins with access to the lesser sac by opening the omentum along the greater curvature of the stomach using harmonic scalpel. Once the stomach is fully exposed and a stay suture is place around the tumor. Gastric wall is divided with cautery 1 cm away from the tumor. Tumor is excised. Gastric wall is sutured with two-layer running suture. No drain was used. Umbilical incision was closed. RESULTS: This procedure was used in one patient with gastric duplication. Operative time was 200 minutes. Blood loss was minimal. Recovery was uneventful and patient discharged on postoperative day 2. Final aspect of the umbilical incision was good. CONCLUSIONS: Gastric resection with single-port laparoscopic platform is feasible and may be safely performed in selected patients. .

INTRODUÇÃO: Ressecções gastrointestinais laparoscópicas com portal único são possíveis, mas os problemas de triangulação e a necessidade de instrumentos articulados dificultam a realização destes procedimentos. OBJETIVO: Apresentar uma alternativa cirúrgica utilizando dispositivo laparoscópico de portal único na ressecção gástrica. TÉCNICA: O paciente é colocado em posição supina e em Trendelenburg reverso com o cirurgião entre as pernas. Auxiliar é posicionado ao lado direito do paciente com o monitor cranialmente situado. Sob anestesia geral, incisão transumbilical de 3 cm é realizada. Através dela, uma plataforma de portal único, com cobertura gelatinosa é introduzida. Três portais de trabalho de 5-12 mm são introduzidos através do dispositivo de portal único. Devido à cobertura gelatinosa, instrumentos articulados não são necessários. O pneumoperitônio é estabelecido em 12 mmHg. É utilizada ótica rígida de 30 graus com introdução de laparoscópio de 10 mm. A operação começa com abertura do omento maior ao longo da grande curvatura do estômago usando bisturi harmônico. Após exposição do estômago, pontos de reparos são colocados e gastrectomia parcial é realizada a cerca de 1 cm do tumor. O procedimento é completado pela sutura contínua da parede gástrica em dois planos. Não é necessária drenagem da cavidade e a incisão umbilical é suturada. RESULTADOS: Este procedimento foi usado em um paciente com a duplicação gástrica. O tempo operatório foi de 200 min. A perda de sangue foi mínima. A recuperação transcorreu sem intercorrências e o paciente recebeu alta no 2º ...

Long segment ileal duplication with extensive gastric heterotopia.

Duplications of the alimentary tract are rare congenital anomalies which can be found at all levels of the alimentary tract. Majority of the duplications present as spherical cysts and usually range from a few millimeters to less than ten centimeters in size. Duplications produce complications such as intestinal obstruction or hemorrhage. A two-month-old infant presented with recurrent episodes of bleeding per rectum. Laparotomy revealed a giant ileal duplicated bowel segment which exhibited extensive gastric heterotopia with focal ulceration.

Gastrointestinal Duplications in Childhood

Gastrointestinal duplications are rare congenital malformation that may require surgical intervention in the neonate, infant, and occasionally the older child. Symptoms produced by duplications vary according to their location, size, type and histology. We report the clinical characteristics and the surgical results of 9 cases of the gastrointestinal duplications treated at at Asan Medical Center between 1989 and 2000. Five patients were boys and four were girls; age of patients ranged from 5 days to 10 years. Eight duplications were cystic and one was tubular. One involved the stomach; five were in the ileum, and two in the cecum. The most common presentation was intestinal obstruction. There was associated anomaly in one patient, pulmonary sequestration and double ureter. Ectopic gastric mucosa was found in two. All patients underwent surgical resection. There was no perioperative mortality or morbidity. Although gastrointestinal duplication is a rare entity, consideration of associated anomalies and being familiar with the anatomy and clinical features are required for adequate management. In cystic form, complete excision is recommended but planned surgery is required for long segment tubular lesion.
