Laparoscopy: advances in biopsy and recording techniques.

We have developed a second puncture accessory set and photographic technique for laparoscopy which are easy to use and potentially safer than others commonly used. A smaller second trocar (4mm) with various biopsy accessories, suction-coagulation cannula, and insulated grasper has been developed and successfully used in a series of more than 400 high risk patients where tissue samples were obtained under local anesthesia without serious complications or fatalities. The smaller size facilitated easy and safe introduction and manipulation. For laparoscopic photography a presterilized quartz rod attached to a sealed flash tube is used which is synchronized with a flash generator and 35-mm camera. An accessory trocar and the quartz rod are introduced under visual guidance parallel to the examining trocar. A separate "modeling" light is incorporated to provide illumination for observation. This photographic technique provides excellent illumination through a smaller trocar and probe than previously reported.

A combined fluoroscopic and endoscopic approach for retrieval of retained stones through the T-tube tract.

Use of the flexible fiberoptic choledochoscope has been suggested as an alternate to the steerable catheter method for extracting retained biliary calculi through the T-tube tract. We found disadvantages to the use of this scope and describe the use of the smaller, more flexible fiberoptic bronchoscope which has facilitated the procedure. The ability to view the calculus through the endoscope while manipulating the stone basket obviates the necessity for fluoroscopic monitoring during this phase and, therefore, results in a significant reduction of radiation exposure to all concerned. In addition, an over-all reduction in procedure time has been achieved by this method.

Pseudosarcoma of the larynx: a comprehensive analysis.

Pseudosarcoma of the larynx is a rare and controversial malignant neoplasm. The presence of a squamous cell carcinoma contiguous with an anaplastic-appearing spindle cell stroma constitutes the distinctive histopathologic appearance of this tumor. Laryngeal pseudosarcoma is most commonly seen as a polypoid glottic mass. Prognosis is best for this lesion and less favorable for sessile tumors and for supraglottic or hypopharyngeal involvement. The tumor demonstrates a biologic behavior similar to squamous cell carcinoma of the larynx, with local aggressiveness and metastatic capability to regional lymphatics and distant sites. Surgery is the treatment of choice, even for T1 glottic lesions, as radiation therapy is associated with a high local recurrence rate.

Minilaparoscopy for blunt abdominal trauma.

A new technique of minilaparoscopy has been developed for use in patients with blunt abdominal trauma. Fifteen injured patients underwent laparoscopy using this new method. Six patients had normal findings, seven patients had evidence of minor injury, and two patients had what seemed to be major injuries. The patients with normal findings or minor injuries were treated nonoperatively and all did well. The two remaining patients underwent laparotomy where serious injuries were found and repaired accordingly. With this modified instrumentation, emergency laparoscopy is simple and rapid enough to become a practical tool in the management of blunt abdominal trauma.

Pediatric otoscopy and photography of the tympanic membrane.

A further miniaturization of the lens telescopes (Hopkins Rod) has resulted in a telescope (length, 6 cm; diameter, 2.7 mm) that is suitable for pediatric otoscopy. The adaptation of otoscopic specula, a lightweight motor-driven remote flash camera, and movie and video photography to this telescope has resulted in a system that represents a significant advance in the examination of the ear. In this study, we document ear diseases in children with the use of color photographs.

Laparoscopic diagnosis of peritoneal mesothelioma. Report of a case and review of the diagnostic approach.

This is the second report of a malignant peritoneal mesothelioma diagnosed by laparoscopy and guided needle biopsy and the first with photographic documentation of the lesion. The case illustrates the following points: (1) diagnosis of peritoneal mesothelioma should be considered in the evaluation of exudative ascites; (2) the only definitive diagnostic procedure is to obtain tissue for histology; and (3) laparoscopy with biopsies under direct vision is an accurate and safe technique which is underutilized and should be considered as the diagnostic procedure of choice when peritoneal disease is suspected.

Improved cannula for operative (cystic duct) cholangiography.

A new S-shaped cystic duct metal cannula was developed and used successfully in 200 cystic duct cholangiograms. It has the advantage of being easy to manipulate because the configuration does not obscure the vision and the resistance is less than that of plastic tubes, facilitating injection with lower pressure. It is much cheaper than the disposable cannulas because it can be reused (autoclaved).

Modern operative fluorocholangiography: utopia or overlooked entity?

A system of image amplification with television fluoroscopy and 100 X 100 mm cut film technique is presented for use in the operating room. Biliary surgery has benefited from this equipment as operative cholangiography has been improved and unnecessary extension of operating time avoided. Applications of the equipment for other procedures are discussed.

Operative fluoroscopy and cholangiography. The use of modern radiologic technics during surgery.

Operative cholangiography as currently performed in many hospitals in the United States may be a cumbersome procedure yielding less than optimal information. For maximal accuracy and diagnostic yield, operative radiographic examination of the biliary tract should include fluoroscopic observation and aimed spot films. The advantages gained by using modern radiologic equipment and technics are increased image clarity, increased capability for functional assessment of a dynamic system, increased efficiency, and decreased radiation hazard. In a series of 100 patients undergoing operative cholangiography by our technic, only one retained stone was demonstrated by postoperative studies. Five anomalies of the ductal system were easily identified and possible injury to the anomalous ducts averted. Considering the morbidity and mortality attendant upon inadequate or inappropriate biliary tract operations, investment in the sophisticated equipment necessary for optimal operative radiography is small indeed.

Operative choledochoscopy. Results of a prospective study in several institutions.

A prospective study from six surgical units utilizing choledochoscopy in conjunction with primary choledocholithotomyand cholangiography resulted in an incidence of less than 2 per cent unsuspected residual biliary calculi. Total reliance on choledochoscopy without associated operative cholangiography is not justified and fraught with error. When there are no calculi in the common duct, the choledochoscope allows the surgeon to shorten exploration time with confidence that the postexploratory cholangiogram will confirm his negative findings. The choledoschoscope is of additional value in the extraction of calculi. Certain considerations in the management of biliary tract tumors also can be helped by the addition of choledochoscopy. The simultaneous presence of calculous disease and biliary tract neoplasm can coexist can be brought to light by the use of the choledochoscope. The incorporation of choledochoscopy, using a rigid Berci-Shore choledochoscope, as part of routine common duct exploration, appears to be warranted.
