Protective ileostomy after low anterior resection for extraperitoneal rectal cancer: does the reversal surgery timing affect closure failure?

The Diagnosis and Evolution of Patients with LARS Syndrome: A Five-Year Retrospective Study from a Single Surgery Unit

OBJECTIVES

The aim of the study was to assess the diagnosis and evolution of low anterior rectal resection syndrome (LARS) in patients admitted to a tertiary surgical center in Romania.

MATERIALS AND METHODS

From 120 patients initially included in the analysis, after applying the exclusion criteria, we selected 102 patients diagnosed and operated on for neoplasm of the upper, middle, and lower rectum for which resection and excision (partial or total) of mesorectum was associated. All the patients we treated in the general surgery department of the County Emergency Hospital of Craiova within a time frame of 5 years (1 October 2017-1 September 2022), and all experienced at least one symptom associated with LARS. The group included 68 men and 34 women aged between 35 and 88, who were followed-up for at least 2 years. Patients with progression of neoplastic disease, with advanced neurological disease, and those who died less than 2 years after surgery were excluded.

RESULTS

The overall incidence varied by gender, site of the tumor (requiring a certain type of surgery), and anastomotic complications, and it was directly proportional to the time interval between resection and restoration of continuity of digestion.

CONCLUSIONS

Obesity, size of the remaining rectum, total excision of the mesorectum, anastomotic complications, and prolonged ileostomy time are cofactors in the etiology of LARS. The LARS score decreased in most patients during the 2-year follow-up, although there were a small number of patients in whom the decrease was insignificant. The persistence of major LARS at 6 months after surgery may predict the need for a definitive colostomy.

3D printing and intelligent technology increase convenience, reliability, and patient acceptance of ostomy nursing: a randomized controlled trial

Traditional ostomy bags commonly cause skin allergy and inflammation around the stoma, as well as leakage. This study aimed to examine the effect of a 3D-printed ostomy bag with sensors and stimulators on stoma nursing. This is a randomized controlled trial. This trial involved 113 distinct individuals who undergo colorectal cancer surgery and intestinal obstruction surgery, with resulting stoma. The date of trial registration was January 17, 2019, and the date of first recruitment was May 1, 2019. Patients were randomized into two groups: intelligent 3D-printed ostomy bag (3D group, n = 57) and Coloplast one-piece pouching systems (control group, n = 56). The shape of ostomy and the surrounding skin of all the 57 patients of the 3D group was scanned by a handheld 3D scanner. Then, the ostomy bag chassis (also known as skin barrier) was 3D printed and an intelligent device adhered to the ostomy bag. The wearing time, leakage rate, the Discoloration, Erosion, and Tissue Overgrowth (DET) score, and the Acceptance of Illness Scale (AIS) were observed. In the 3D-printed bag group, the time to wear (0.7 ± 0.4 m) was significantly shorter than that of the control group (9.1 ± 3.5 m). The leakage rate of 3D-printed bag (1.75%) was significantly lower than that of the control group (16.1%). The DET score for the 3D-printed bag group was also lower than that of the control group, and the AIS score for the 3D-printed bag group was higher than that of the control group. The 3D-printed ostomy bags and the linked computer program can significantly reduce wearing time, leakage rate, and stoma complications. This may improve the quality of home ostomy care for patients and reduce the incidence of skin complications around the stoma.Registration number: ChiCTR1900020752.

A comprehensive evaluation of 80 consecutive robotic low anterior resections: impact of not mobilizing the splenic flexure alongside low-tie vascular ligation as a standardized technique

Rectal cancer surgery represents challenges due to its location. To overcome them and minimize the risk of anastomosis-related complications, some technical maneuvers or even a diverting ileostomy may be required. One of these technical steps is the mobilization of the splenic flexure (SFM), especially in medium/low rectal cancer. High-tie vascular ligation may be another one. However, the need of these maneuvers may be controversial, as especially SFM may be time-consuming and increase the risk of iatrogenic. The objective is to present the short- and long-term outcomes of a low-tie ligation combined with no SFM in robotic low anterior resection (LAR) for mid- and low rectal cancer as a standardized technique. A retrospective observational single-cohort study was carried out at Reina Sofia University Hospital, Cordoba, Spain. 221 robotic rectal resections between Jul-18th-2018 and Jan-12th-2023 were initially considered. After case selection, 80 consecutive robotic LAR performed by a single surgeon were included. STROBE checklist assessed the methodological quality. Histopathological, morbidity and oncological outcomes were assessed. Anastomotic stricture occurrence and distance to anal verge were evaluated after LAR by rectosigmoidoscopy. Variables related to the ileostomy closure such as time to closure, post-operative complications or hospital stay were also considered. The majority of patients (81.2%) presented a mid-rectal cancer and the rest, lower location (18.8%). All patients had adequate perfusion of the anastomotic stump assessed by indocyanine green. Complete total mesorectal excision was performed in 98.8% of the patients with a lymph node ratio < 0.2 in 91.3%. The anastomotic leakage rate was 5%. One patient (1.5%) presented local recurrence. Anastomosis stricture occurred in 7.5% of the patients. The limitations were small cohort and retrospective design. The non-mobilization of the splenic flexure with a low-tie ligation in robotic LAR is a feasible and safe procedure that does not affect oncological outcomes.
