Laparoscopic splenectomy for isolated sarcoidosis of the spleen

Sarcoidosis is a granulomatous disease of unknown etiology. Over 90% of patients with sarcoidosis present with pulmonary findings at the time of diagnosis. Extrapulmonary involvement is common, including the liver, eyes, central nervous system, lymph nodes, and joints. However, isolated granulomatous disease confined to the spleen is rare. This report documents a rare case of isolated granulomatous disease of the spleen diagnosed and treated laparoscopically. A 47-year-old female presented to her internist with nausea and mild epigastric abdominal pain. Laboratory evaluation revealed slightly elevated bilirubin and liver function tests as well as neutropenia. An abdominal ultrasound revealed normal biliary and pancreatic anatomy and multiple splenic lesions. Computed tomography of the abdomen confirmed the multiple hypodense lesions within the spleen. The differential diagnosis at this time included neoplasm, infection, and autoimmune etiologies. Subsequently, the patient underwent a diagnostic laparoscopy with splenectomy. No other intra-abdominal pathology was found. Pathology revealed multiple noncaseating, splenic granulomas. Isolated extrapulmonary manifestations of sarcoidosis occur in only 10% of these patients. Moreover, isolated splenic sarcoidosis is rare. Currently, the literature documents only two prior cases of sarcoidosis presenting with isolated splenic lesions. Primary management consists of medical therapy with prednisone, methotrexate, and/or antimalarial drugs. Indications for surgery include symptomatic splenomegaly, severe hypersplenism, prophylaxis for splenic rupture, and neoplastic exclusion. Our patient required a laparoscopic splenectomy for diagnostic purposes and neoplastic exclusion. Once diagnosed, patients require continual follow-up for systemic manifestations and associated complications of sarcoidosis. © Mary Ann Liebert, Inc

Laparoscopic splenectomy for metastatic squamous cell cancer of the neck

Squamous cell carcinoma (SCC) spreads through direct extension, lymphatic vessels, and, rarely, hematogenous routes. The most common malignancies to metastasize to the spleen include carcinomas of the breast, lung, and melanoma. We present an unusual case of SCC of the neck with splenic metastases. The patient presented with a primary solid tumor of the neck that extended into the surrounding soft tissues, including the internal jugular vein and regional lymph nodes. A metastatic work-up with a positron emission tomograph showed enhancement in the left upper quadrant. A computed tomograph (CT) was then performed. The CT revealed three distinct splenic lesions, the largest measuring 6 × 6.5 × 2.5 cm. Subsequently, the patient was scheduled for a splenectomy. At the time of operation, diagnostic laparoscopy revealed only the splenic lesions. A laparoscopic splenectomy was performed successfully and the patient was started on a regular diet on postoperative day 1. This paper describes the first documented case of SCC of the neck with splenic metastases. The lesion was diagnosed and treated laparoscopically. The case is described in detail along with the clinical implications of this rare finding. © Mary Ann Liebert, Inc

An experimental study in six fresh human cadavers using a novel approach to avoid abdominal wall incisions in total colectomy: totally transanal laparoendoscopic single-site pull-through colectomy with J-pouch creation

The use of transanal laparoscopic access to completely avoid abdominal wall incisions represents the most current evolution in minimally invasive surgery. The combination of single-site surgery and natural orifice transluminal endoscopic surgery (NOTES (TM)) can be used for totally transanal laparoendoscopic pull-through colectomy with J-pouch creation (TLPC-J). The aim of the present study was to provide evidence for the feasibility of TLPC-J in adult human cadavers. TLPC-J was performed in six fresh adult human cadavers. The procedure involved endorectal submucosal dissection from 1 cm above the dentate line to a point above the peritoneal reflection, where the rectal muscle was divided circumferentially. The edge of the mucosal cuff was closed distally in order to prevent fecal contamination and the endorectal tube was placed back into the abdomen. A Triport+(TM) or QuadPort+(TM) system was introduced transanally, and it served as a multiport device (MD). Resection of the entire colon, mobilization of the distal ileal segment, and extracorporeal suture of the ileal J-loop were performed via the transanal approach. The J-pouch was created using Endo GIA (TM). After removal of the MD, the J-pouch was sutured to the rectal wall. TLPC-J was performed in all cadavers, with a mean operation duration of 236 +/- A 22 min. Conversion to either transabdominal laparoscopy or laparotomy was not required in any of the cadavers. No bowel perforation or damage to other organs was observed. The use of a curved endoscope greatly facilitated visualization during transanal laparoscopic dissection for partial and total colectomy, making the procedure feasible. All specimens were retrieved through the anus, eliminating the need for additional transabdominal incisions. TLPC-J was technically feasible in adult human cadavers, and abdominal wall incisions were not required. However, clinical studies are needed to determine its feasibility in living adults

Consensus statement of the consortium for LESS cholecystectomy

Many surgeons attempting Laparo-Endoscopic Single Site (LESS) cholecystectomy have found the operation difficult, which is inconsistent with our experience. This article is an attempt to promote a standardized approach that we feel surgeons with laparoscopic skills can perform safely and efficiently. This is a four-trocar approach consistent with the four incisions utilized in conventional laparoscopic cholecystectomy. After administration of general anesthesia, marcaine is injected at the umbilicus and a 12-mm vertical incision is made through the already existing anatomical scar of the umbilicus. A single four-trocar port is inserted.A5-mm deflectable-tip laparoscope is placed through the trocar at the 8 o'clock position, a bariatric length rigid grasper is inserted through the trocar at the 4 o'clock position (to grasp the fundus), and a rigid bent grasper is placed through the 10-mm port (to grasp the infundibulum). This arrangement of the instruments promotes minimal internal and external instrument clashing with simultaneous optimization of the operative view. This orientation allows retraction of the gallbladder in a cephalad and lateral direction, development of a window between the gallbladder and the liver which promotes the "critical view" of the cystic duct and artery, and provides triangulation with excellent visualization of the operative field. The operation is concluded with diaphragmatic irrigation of marcaine solution to minimize postoperative pain. Standardization of LESS cholecystectomy will speed adoption, reduce intraoperative complications, and improve the efficiency and safety of the approach. © Springer Science+Business Media, LLC 2012.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
