The endoluminal space is tight and small, and during the procedure, this tight space is accessed by the 40 mm GelPOINT® Path transanal platform (Applied Medical, Rancho Santa Margarita, CA, USA). Most of the trocar space is occupied by the 25 mm port of the da Vinci SP® system. There is limited space for an additional trocar, and the full mobility of this trocar is restricted; hence there is a need for an effective suction irrigator during these procedures. Although the da Vinci SP® system has four instrument capabilities, it does not have a suction irrigation instrument. To address this issue, we tested a Remotely Operated Suction Irrigation System (ROSI™) (VTI, Nashua, NH, USA) in three patients undergoing da Vinci SP® submucosal dissection.IMPACT OF INNOVATIONThe impact of innovation is the evaluation of a flexible suction irrigator during endorobotic submucosal dissection (ERSD), addressing space constraints and enhancing surgical precision.TECHNOLOGY MATERIALS AND METHODSThis was a single-center retrospective observational study involving three patients who underwent ERSD, between February 2023 and May 2023. ROSI™ was used selectively for rectal lesions.PRELIMINARY RESULTSThe first patient was a 67-year-old male with a 30 mm tubulovillous adenoma found in the rectum at 4 cm. The second patient was a 49-year-old female, referred after a screening colonoscopy, with a 40 mm rectal mass 12 cm from the anal verge. A biopsy revealed a tubular adenoma without dysplasia. The last patient was a 66-year-old male with a 25 mm tubulovillous adenoma with a focal high-grade dysplasia at 10 cm. There was no evidence of invasive carcinoma or lymph node metastasis on MRI in any of the patients. The patients were placed in a modified lithotomy position, and the GelPOINT® Path was inserted. A silk suture was attached at the proximal end of ROSI™ to facilitate tubing manipulation. ROSI™ was freely passed into the endoluminal space through the gel using a surgical clamp. Any bleeding during the operation was aspirated and irrigated using ROSI™ with the assistance of bipolar forceps. All surgeries were completed without complications and the patients were discharged on the same day.CONCLUSION AND FUTURE DIRECTIONSROSI™ is a flexible foot pedal-controlled suction irrigator that can facilitate da Vinci SP® submucosal dissection. The flexibility and controllability of ROSI in the surgeon's hand may qualify it as an essential tool for performing ERSD and possibly other TAMIS procedures.","PeriodicalId":11299,"journal":{"name":"Diseases of the Colon & Rectum","volume":null,"pages":null},"PeriodicalIF":3.9,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142201227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Median follow-up was 45 months. Recurrence-free survival was worse for liver-first versus primary-first/simultaneous groups (median 12 versus 16 months, p = 0.02), driven by three-year extrahepatic recurrence-free survival of 19%, 58%, and 50% for liver-first, primary-first, and simultaneous groups, respectively.

Conventional laparoscopic instruments are rigid and straight, which can restrict optimal access to the target organ. Although the use of robotic surgical platforms with flexible wrists has significantly reduced movement restrictions and surgeon fatigue, their high cost remains a barrier to widespread adoption.IMPACT OF INNOVATIONRecent technological advancements in laparoscopic instruments have led to the development of an articulating flexible hand-held device that enables greater dexterity and easier access to difficult anatomical locations. This technology has the potential to improve surgical outcomes by using multiple degrees of freedom to perform complex surgical procedures with greater precision.TECHNOLOGY, MATERIALS, AND METHODSThe ArtiSential® product line comprises over 30 end-effectors, such as scissors, hooks, and graspers. The benefits of this device are evident throughout the total mesorectal excision, especially when approaching the left lateral side of the mesorectum (the side opposite the surgeon) or the deepest part of the pelvis around the levator ani muscle. The Samsung Medical Center Institutional Review Board approved this study (2022-01-174).PRELIMINARY RESULTSA 79-year-old male with rectal cancer located 9 cm from the anal verge underwent an laparoscopic ultralow anterior resection using ArtiSential®. There were no intraoperative complications. The pathologic results showed that the tumor was at pT3N0 stage. The patient was discharged without any complications.CONCLUSION AND FUTURE DIRECTIONSThe articulating device can be effectively used for laparoscopic surgery, but has some challenges related to the bulky handpiece and learning curve. A multicenter prospective cohort study to compare the outcomes of articulating laparoscopic surgery and robotic surgery for patients with rectal cancer is oncoing (clinicaltrials.gov number: NCT05566249).","PeriodicalId":11299,"journal":{"name":"Diseases of the Colon & Rectum","volume":null,"pages":null},"PeriodicalIF":3.9,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142201225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Refractory stenosis was defined as obstructive symptoms associated with an anastomotic stenosis upon rectal exam without improvement after serial anal dilatations. Under general anesthesia, an injection of 10mg delayed-action steroid per quadrant was combined with a radial incision of the stenosis using monopolar cautery.PRELIMINARY RESULTSCombined radial incision and steroid injection was performed in 4 children, for either early or late refractory stenosis. This resulted in improvement of refractory anastomotic stenosis, avoiding a redo pull-through in 75% of patients. One child presented with transient improvement after combined radial incision and steroid injection but developed recurrent stenosis despite additional combined radial incision and steroid injection and redo pull-through.

These patients had either bulking tumor scheduled for multivisceral resection, a strong desire for organ preservation, or potentially resectable metastatic lesions.MAIN OUTCOME MEASURESPathological complete response, clinical complete response, toxicity, R0 resection rate, and complications were evaluated.RESULTSPatients tolerated preoperative immunotherapy well. The R0 resection rate was 95.2% and the pathological complete response rate was 47.6%. Three patients (12.5%) were evaluated as clinical complete response and then underwent \"watch and wait\". One half of the cT4b patients were spared multivisceral resection, while 60% (3/5) achieved pathological complete response. All three patients with liver metastases obtained CR of all liver lesions after programmed death-1 blockade treatment.
