Diagnostic laparoscopy in pancreatic tumors remains controversial. The main argument in favor of this procedure is that it helps prevent a delay of chemotherapy in cases of unresectable tumors or peritoneal/lymph node metastasis. We report a technique of performing this exploration through single-incision laparoscopy. VIDEO: The umbilicus is incised, and a purse-string suture is applied. An 11-mm nondisposable trocar is inserted for a 10-mm, 30° angled scope. Curved and reusable instruments (Karl Storz-Endoskope, Tuttlingen, Germany) are inserted transumbilically. Laparoscopic exploration of the cavity allows the visualization of suspected peritoneal or lymph node metastasis. Peritoneal lavage for cytology is performed. Biopsy is accomplished through the curved shape of the instruments, which establishes the working triangulation inside the abdomen as well as externally. Laparoscopic ultrasonography of the liver and of the pancreas (after opening the lesser sac) is performed after replacement of the 11-mm trocar with a 13-mm trocar and the use of a 5-mm scope. The procedure can be continued either by laparoscopy or by open surgery. At completion, the umbilicus is meticulously closed to avoid complications. Operative time is 45-60 minutes, blood loss is minimal, and the size of the umbilical incision is less than 15 mm. In case of unresectable tumors or peritoneal metastasis, single-access diagnostic laparoscopy for pancreatic tumors permits the start of chemotherapy after less than 7 days. Curved and reusable instruments allow the achievement of ergonomic conditions as classic laparoscopy, without increasing of conventional laparoscopic cost. Source

The authors report resection of a gastric benign tumor through single-incision laparoscopy, guided by peroperative gastroscopy. VIDEO: A 25-year-old man consulted after diagnosis of a 40 × 20 cm(2) endoluminal lesion of the gastric cardia. Preoperative work-up showed a stromal tumor with invasion of the muscular layer. The umbilical scar was incised and, after placement of a purse-string suture, an 11-mm nondisposable trocar was inserted for a 10-mm 30° angled scope. Curved and reusable instruments (Karl Storz-Endoskope, Tuttlingen, Germany) and straight ultrasonic shears (Ethicon Endosurgery, Cincinnati, OH, US) were inserted transumbilically. Peroperative gastroscopy located the lesion on the smaller gastric curvature, 1 cm from the gastroesophageal junction. A stitch was placed in the center of the lesion, and gastroscopic grasper helped in maintaining the limits of resection. Gastrostomy was closed using two converting absorbable running sutures. Because of the curves of the instruments there was no conflict between the instruments' tips inside the abdomen (Fig. 1a), or between the surgeon's hands outside the abdomen (Fig. 1b). Leak test with the gastroscope checked the integrity of the suture. The specimen was retrieved transumbilically in a plastic bag. Operative time was 150 min, and the umbilical incision was less than 15 mm. The patient was discharged after 5 days, and he is doing well 3 months postoperatively. Laparoscopic gastric resection can be safely performed through a single-access. Peroperative gastroscopy permits the limits of resection to be precisely determine, and use of curved and reusable instruments allows surgeon to achieve ergonomic conditions as in classic laparoscopy, without increasing the laparoscopic cost.

Minimally invasive surgery has been expanded recently by an increasing interest in single-incision, single-port, single-access laparoscopy (SAL). The main drawbacks of this laparoscopic approach include the clashing of the instruments and/or the crossing of the surgeon's hands due to the single-access site and an increase in the cost of the procedures due to the use of disposable materials. Furthermore, one of the rules of laparoscopy, which is to maintain the surgeon's two effectors at the right angle using the optical system as the bisector of this angle, is frequently lost during SAL. To solve these problems, curved reusable instruments for basic and advanced procedures in SAL have been developed based on this laparoscopic principle. The technique consists of the placement of a standard 11-mm reusable trocar, a 10-mm standard rigid scope, and the insertion of curved reusable instruments transabdominally without trocars. The 2.5-year experience in 265 patients is reported here. © 2012 Informa Healthcare. Source

Single-incision laparoscopy (SIL) gained in popularity in the last 5-7 years, as a new philosophy has emerged to reduce the invasiveness of minimally invasive surgery. Various abdominal procedures using fewer and smaller trocars in order to obtain pure SIL have been described. To overcome some known problems of SIL, such as establishing the conventional multiport laparoscopic working triangulation, the non-ergonomic positioning of the surgeon, and the increased cost of each procedure, a particular SIL technique has been developed. The technique involves reusable trocars along with specially designed DAPRI curved reusable instruments introduced through the same incision but laterally to the optical system. Hence, the main principle of conventional multiport laparoscopy--working in an appropriate triangulation while maintaining the scope in the center--is respected. The final scar is 15 mm and the cost of the procedure remains unchanged because reusable materials are used. All the abdominal procedures, including upper and lower gastrointestinal, colorectal, hepatobiliopancreatic, solid organs, gynecologic and abdominal wall hernia repair, are here reported, as are the indications for and the results after 740 procedures. In conclusion, SIL has to be considered as one of the most attractive techniques of the new minimally invasive era. © 2014 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and Wiley Publishing Asia Pty Ltd.

Esophagectomy can be performed by different minimal invasive techniques. We report a technique of Ivor Lewis esophagogastrectomy with manual anastomosis performed by thoracoscopy in prone position. Readers are encouraged to view the streaming video that accompanies this article. A 51-year-old man was consulted for adenocarcinoma of the distal esophagus without lymph nodes invasion. Anesthesia was realized using a double-lumen endotracheal tube. The procedure started with the patient supine, and five abdominal trocars were placed. Celiac lymphadenectomy, wide Kocher maneuver, and pyloroplasty were performed. A wide gastric tube was advanced through the hiatus into the right chest. Subsequently the patient was placed in prone position and three trocars (two 5-mm, one 10-mm) were placed in the 5th, 7th, and 9th right intercostal space. The intrathoracic esophagus was dissected, and mediastinal lymphadenectomy with en bloc resection of the left inferior mediastinal pleura was performed. After sectioning the azygos vein, the esophagus was transected by scissors 1 cm cranially. A completely thoracoscopic manual double-layer anastomosis was performed using running sutures with PDS 2/0 (externally) and Maxon 4/0 (internally). Finally the patient was replaced supine; the gastric tube was fixed to the hiatus, and the specimen was retrieved by suprapubic incision. Thoracoscopy lasted 157' (anastomosis 40'), laparoscopy 160', and second laparoscopy 20'. Blood loss was 170 cc. The patient was discharged on postoperative day 6. Thoracoscopy in prone position allows the surgeon to perform a thoracoscopic esogastric anastomosis completely manually using only three trocars and without selective lung desufflation. Source
