- A novel approach for the treatment of pelvic abscess: transrectal endoscopic drainage facilitated by transanal endoscopic microsurgery access(2012) MARTINS, B. C.; MARQUES, Carlos Frederico Sparapan; NAHAS, Caio Sergio Rizkallah; HONDO, Fabio Yuji; POLLARA, Wilson; NAHAS, Sergio Carlos; RIBEIRO JUNIOR, U.; CECCONELLO, Ivan; MALUF-FILHO, FauzePostoperative pelvic abscesses in patients submitted to colorectal surgery are challenging. The surgical approach may be too risky, and image-guided drainage often is difficult due to the complex anatomy of the pelvis. This article describes novel access for drainage of a pelvic collection using a minimally invasive natural orifice approach. A 37 year-old man presented with sepsis due to a pelvic abscess during the second postoperative week after a Hartmann procedure due to perforated rectal cancer. Percutaneous drainage was determined by computed tomography to be unsuccessful, and another operation was considered to be hazardous. Because the pelvic fluid was very close to the rectal stump, transrectal drainage was planned. The rectal stump was opened using transanal endoscopic microsurgery (TEM) instruments. The endoscope was advanced through the TEM working channel and the rectal stump opening, accessing the abdominal cavity and pelvic collection. The pelvic collection was endoscopically drained and the local cavity washed with saline through the scope channel. A Foley catheter was placed in the rectal stump. The patient's recovery after the procedure was successful, without the need for further intervention. Transrectal endoscopic drainage may be an option for selected cases of pelvic fluid collection in patients submitted to Hartmann's procedure. The technique allows not only fluid drainage but also visualization of the local cavity, cleavage of multiloculated abscesses, and saline irrigation if necessary. The use of TEM instrumentation allows safe access to the peritoneal cavity.

- Etiology, endoscopic management and mortality of upper gastrointestinal bleeding in patients with cancer(2013) MALUF-FILHO, Fauze; MARTINS, Bruno da Costa; LIMA, Marcelo Simas de; LEONARDO, Daniel Valdivia; RETES, Felipe Alves; KAWAGUTI, Fabio Shiguehissa; SATO, Cezar Fabiano Manabu; HONDO, Fabio Yuji; SAFATLE-RIBEIRO, Adriana Vaz; RIBEIRO JR., UlyssesBackground: The source and outcomes of upper gastrointestinal bleeding (UGIB) in oncologic patients are poorly investigated. Objective: The study aimed to investigate these issues in a tertiary academic referral center specialized in cancer treatment. Methods: This was a retrospective study including all patients with cancer referred to endoscopy due to UGIB in 2010. Results: UGIB was confirmed in 147 (of 324 patients) referred to endoscopy for a suspected episode of GI bleeding. Tumor was the most common cause of bleeding (N = 35, 23.8%), followed by varices (N = 30, 19.7%), peptic ulcer (N = 29, 16.3%) and gastroduodenal erosions (N = 16, 10.9%). Among the 32 patients with cancer of the upper GI tract, the main causes of bleeding were cancer (N = 27, 84.4%) and peptic ulcer (N = 5, 6.3%). Forty-one patients (27.9%) presented with bleeding from the primary tumor or from a metastatic lesion, and seven received endoscopic therapy, with successful initial hemostasis in six (85.7%). Rebleeding and mortality rates were not different between endoscopically treated (N = 7) and nontreated (N = 34) patients (28.6% vs. 14.7%, p = 0.342; 43.9% vs. 44.1%, p = 0.677). Median survival was 20 days, and the overall 30-day mortality rate was 44.9%. There was no predictive factor of mortality or rebleeding. Conclusion: Tumor bleeding is the most common cause of UGIB in cancer patients. UGIB in cancer patients correlates with a high mortality rate regardless of the bleeding source. Current endoscopic treatments may not be effective in preventing rebleeding or improving survival.
