Rectoscopy and proctoscopy are established methods for diagnosing and treating rectal disease. The combination with video endoscopic technologies permits extraordinarily good visualization as well as clear documentation of findings and extends the range of indications to complex minimally invasive procedures such as transanal rectal surgery.
For these indications, KARL STORZ offers a wide range of products to hospitals and offices, ranging from instruments for rectal biopsies and polyp removal, optical forceps, and instruments for treating hemorrhoids to video endoscopic instruments for transanal endoscopic operation (TEO) and video-assisted anal fistula treatment (VAAFT).

E.P.Si.T. – Endoscopic Pilonidal Sinus Treatment

The pilonidal sinus is an acute or chronic inflammatory process in the subcutaneous adipose tissue, often occurring in the sacrococcygeal region1. E.P.Si.T. – Endoscopic Pilonidal Sinus Treatment – proceeds in two phases. In the first – diagnostic – phase, the sinus cavity and the sinus tracts are examined. The aim of the second – therapeutic – phase is to ablate the abscess cavity and to eliminate the fistula2. Both phases are performed under direct endoscopic control.

Special Features:
- E.P.Si.T. can be performed in an outpatient setting
- Ablation of the abscess cavity and elimination of the fistula under direct vision
- High patient satisfaction3
- Straightforward, safe, effective and reproducible method of treatment3
- Instruments can also be used to treat anal fistulas (VAAFT technique)

Video-Assisted Anal Fistula Treatment
The VAAFT technique is suitable for the surgical treatment of complex anal fistulas and recurrences. VAAFT – Video Assisted Anal Fistula Treatment – proceeds in two phases. The purpose of the first – diagnostic – phase is to inspect the fistula pathway and to locate the internal fistula opening. The goal of the second – therapeutic – phase is the complete destruction of the fistula epithelium. Both phases are performed under direct endoscopic control.

Special Features:
- Exact localization of the internal fistula opening under visual control
- Complete elimination of the fistula from the inside
- Minimal postoperative trauma
- Significant time and cost-saving potential
- Fully autoclavable

TEO® – Transanal Endoscopic Operations

The minimally invasive transanal platform for the treatment of rectal neoplasia Transanal Endoscopic Operations (TEO®) combines the minimal invasiveness of an intervention via a natural body orifice (NOTES) with the precision of resection under endoscopic microsurgery.

Special Features:
- Available in lengths of 7.5, 15 and 20 cm
- Compatible with all standard camera systems for laparoscopy
- Mechanical holding arm enables the platform to be placed in a very stable position

TEO® Platform with Flexible Working Attachment and High-Flow Adaptor – B-PORT

TEO® (Transanal Endoscopic Operations) combines the minimal invasiveness of an intervention via a natural orifice (NOTES) with the precision of resection under visual control. A wide-lumen rectoscope enables precise guidance of operating instruments under endoscopic control. In cooperation with Prof. Luigi Boni, Milan, Italy, it was possible to optimize the TEO® platform for TaTME (Transanal Total Mesorectal Excision).

Special Features:
- Great freedom of movement thanks to flexible working attachment
- Instruments up to size 15 mm can be used
- The high-flow adaptor enables a fast and stable pneumorectum as well as effective smoke evacuation
- Straight distal end simplifies the placement of an endoscopic purse-string suture Also suitable for TaTME


The reusable D-PORT was designed and optimized for transanal surgery. It is also possible to perform Transanal Total Mesorectal Excision (TaTME) with this platform.

Special Features:
- Simultaneous CO2 insufflation and smoke / gas evacuation possible
- Great freedom of movement due to flexible sealing cap
- Small outer diameter of 30 mm facilitates insertion in the anal canal
- Free choice of telescopes (5 mm or 10 mm)
- Reusable and thus cost-effective

ENDOFLATOR® 50 and S-PILOT® – The Perfect Combination

The ENDOFLATOR® 50 in conjunction with the KARL STORZ S-PILOT® creates the perfect prerequisites for optimal smoke evacuation. To make full use of the excellent flow rate provided by the insufflator, appropriate accessories are required.

Special Features:
- Stable OR field thanks to innovative regulation
- Gas heating adapts to various ambient conditions and reliably prevents telescope fogging
- Creates optimal viewing conditions and a stable OR field, even in small cavity surgery
- Rectoscope for Video Documentation – RECTOVISION® with Sliding

Rectoscope for Video Documentation – RECTOVISION® with Sliding Cap

The combination of laparoscopic and rectoscopic technologies permits exceptionally good visualization and documentation of the intraluminal conditions in patients undergoing coloproctological interventions. Video rectoscopy is a straightforward and convenient procedure. RECTOVISION® is intended for use in both outpatient settings and surgical departments.

Special Features:
- Clear, high-resolution display of even the finest details
- Fully reusable; long service life
- Can be used with all 10 mm telescopes – also in conjunction with NIR/ICG for intraluminal perfusion assessment
- Stable examination field thanks to airtight sliding cap


TROIDL SILVER SCOPE® Flexible Rectoscope
The flexible TROIDL SILVER SCOPE® rectoscope combines the fundamental advantages of flexible endoscopy with the application possibilities of rectoscopy.

SAAD Retrieval Tube

For avoiding minilaparotomy in laparoscopic colon resection
Laparoscopic techniques in colorectal resection have become increasingly established in recent years as a standard procedure in colorectal surgery1,2 although a minilaparotomy is still necessary to recover the specimen. The SAAD retrieval tube – which can be introduced both transanally and transvaginally – was designed to avoid minilaparotomy and thus significantly reduce the morbidity of the abdominal wall in the form of wound infections, postoperative pain and the formation of abdominal hernias3.

Special Features:
- Smooth and gentle insertion thanks to anatomically adapted shape The flexible working insert allows instrument use without the loss of CO2
