Robotic Sigmoidectomy With Natural Orifice Specimen Extraction: A Single-Center Experience.
Curēus 2023 December
Background Natural orifice specimen extraction (NOSE) involves the removal of specimens through a naturally occurring orifice, such as the anus, rather than trans-abdominal extraction. NOSE procedures have been shown to significantly reduce postoperative complications and improve healing. Objective The purpose of this case series is to report the outcomes of 27 patients undergoing sigmoidectomies through natural orifice specimen extraction. Materials and methods We carefully recorded demographic data on age and BMI, as well as operative data on surgical indication, and length of stay. We also collected data on postoperative complications, including infection, hernia, wound dehiscence, urinary tract infections (UTIs), or anastomotic leaks. Results Our patients were majority female ( n = 21, 77.8%) with a median age of 53.5 (range: 25-79) and median BMI of 33.2 kg/m2 (range: 16.7 - 48.3 kg/m2 ). Thirteen patients (48.1%) were obese (BMI > 30.0 kg/m2 ). The majority of these patients underwent sigmoidectomies for benign conditions such as recurrent diverticulitis ( n = 9, 33.3%), rectal prolapse ( n = 8, 29.6%), perforated diverticulitis ( n = 3, 11.1%), colovesical fistula ( n = 3, 11.1%), and abdominal abscess ( n = 3, 11.1%) (Table 1). One patient was receiving treatment for sigmoid cancer. The average estimated blood loss was 63.26 mL. The average hospital stay was 3.61 days. Three patients (11.1%) developed a fever postoperatively (temperature >= 100.4 F), which resolved the day after. One patient completed a post-operative hospital stay of 19 days for dialysis and rehab placement. No patients (0.0%) experienced any postoperative complications, including wound infection, hernia, dehiscence, UTIs, or anastomotic leakages. There was no postoperative mortality. Conclusions Our study demonstrates the practicality and safety of NOSE procedures for sigmoidectomies as an alternative to transabdominal approaches to treat benign colon diseases.
