Transrectal endoscopic drainage with vacuum-assisted therapy in patients with anastomotic leaks following rectal cancer resection

Effect of refined management in operating room nursing on surgical efficiency and nursing satisfaction during laparoscopic radical resection of colon cancer

AIM

To assess the effect of refined management in the operating room nursing on surgical efficiency and nursing satisfaction during laparoscopic radical resection of colon cancer.

METHODS

In this retrospective study, 100 patients with laparoscopic radical resection of colon cancer were enrolled into this study. There were 51 patients who received refined management (the observation group) and 49 patients who received routine nursing intervention (the control group). The effect of refined management in the operating room nursing was evaluated by comparing the surgical efficiency, quality of care ratings, pain scores, and the nursing satisfaction between the two groups.

RESULTS

The preoperative preparation time, surgical time, intraoperative bleeding volume, and time to first postoperative defecation in the observation group were all less than those in the control group after nursing intervention (all P<0.05). The observation group had higher scores than the control group in five categories: operating room environment and safety, drug and instrument management, hygiene and sterilization, nursing records, and nursing professionalism (all P<0.05). The numerical rating scale (NRS) pain scores of the patients in the observation group were lower than those of the control group at 12, 24, and 48 hours postoperatively (all P<0.05). The rate of satisfaction in the observation group was 96.1%. This was higher than the 91.8% in the control group (P<0.05). The multivariate regression analysis demonstrated that refined management intervention is an independent factor for patients' prognosis.

CONCLUSION

The implementation of a refined management model in the operating room is effective in improving the quality of surgical care and surgical efficiency, and increasing patient satisfaction with nursing staff.

Transanal total mesorectal excision (TaTME) in rectal cancer treatment within an expert center

The objective of this study was to evaluate treatment outcomes in patients who underwent the TaTME procedure for cancer of the middle and low rectum in an expert center. Prospective analysis of the outcomes of all consecutive patients treated using the TaTME technique for cancer of the middle and distal rectum at the our medical center between March 1, 2015, and March 31, 2022. A total of 128 patients (34 women, 94 men; mean age 66.01 [38-85] years) with cancer of the middle and distal rectum qualified for TaTME. TaTME procedures were performed in 127/128 (99.22%) patients. Complications of surgery were observed in 22/127 (17.32%) patients. Negative proximal and distal margins were confirmed in all 127 patients. Complete (R0) resection of the mesorectum was confirmed in 125/127 (98.43%) and nearly complete (R1) resection was confirmed in 2/127 (1.57%) patients. The average follow-up period was 795 days (296-1522) days. Local recurrence was detected during the follow-up period in 2/127 (1.57%) patients. This study showed that the TaTME procedure is an effective and safe method for the minimally invasive treatment of middle and low rectal cancers, particularly within an expert center setting.

Assessment of the efficacy of Handmade Vacuum-Assisted Sponge Drain for Treatment of Anastomotic leakage after Low Anterior Rectal Resection

Anastomotic leakage is one of the major complications of colorectal surgery, which might lead to reoperation, increased hospital stays, further intervention and mortality. Vacuum-assisted closure by devices such as Endo-SPONGE® produced by (B-Braun Medical B.V.) is currently being used to treat leakage and fistula. In this study, we aimed to assess the handmade vacuum-assisted sponge drain for anastomotic leakage following low anterior resection. This prospective study included 22 patients who had undergone sponge drain placement to treat anastomotic leakage. All patients had anastomotic leaks or defects after left anterior rectal resection (LAR) without ileostomy. They were treated with neo-adjuvant chemotherapy before the surgery and then subjected to rigid recto-sigmoidoscopy for 30 days following the operation. Any sign of leakage, such as perianal and pelvic pain, was immediately identified and followed up with a CT scan and another recto-sigmoidoscopy. Twenty-two patients were enrolled in this study, 12 men (54.5%) and 10 women (47.4%). All patients had received neo-adjuvant chemotherapy with an average follow-up of 22.30 ± 3.81. 75% of patients (15 cases) were successfully treated, and 17 patients (85%) underwent successful ostomy closure. Treatment failed in 5 patients (25%), including three men and two women. This study shows that handmade vacuum-assisted sponge drain is a cost-effective method of anastomotic leakage management with efficacy similar to that of Endo-SPONGE^®.

Endoscopic fully covered self-expandable metal stent and vacuum-assisted drainage to treat postoperative colorectal cancer anastomotic stenosis with fistula

BACKGROUND

Digestive tract reconstruction is required after the surgical resection of a colorectal malignant tumor. Some patients may have concomitant anastomotic complications, such as anastomotic stenosis with fistula (ASF), postoperatively. Therefore, we evaluated the efficacy and safety of endoscopic fully covered self-expandable metal stent and homemade vacuum sponge-assisted drainage (FSEM-HVSD) for the treatment of ASF following the radical resection of colorectal cancer.

METHODS

Patients treated with FESM-HVSD were prospectively analyzed and followed up for ASF following colorectal cancer treatment in our medical center from 2017 to 2021 for the observation and evaluation of its safety and efficacy.

RESULTS

Fifteen patients with a mean age of 55.80 ± 11.08 years were included. Nine patients (60%) underwent protective ileostomy. All 15 patients were treated with endoscopic FSEM-HVSD. The median time from the index operation to the initiation of FSEM-HVSD was 80 ± 20.34 days in patients who underwent protective ileostomy versus 11.4 ± 4.4 days in those who did not. The average number of endoscopic treatments per patient was 5.70 ± 1.25 times. The mean length of hospital stay was 27.60 ± 4.43 days. FSEM-HVSD treatment was successful in 13 patients, and no patients had any complications. The follow-up time was 1 year. Twelve of 15 (80%) patients achieved prolonged clinical success after FSEM-HVSD treatment, 1 experienced anastomotic tumor recurrence and underwent surgery again, and 1 patient required balloon dilation for anastomotic stenosis recurrence.

CONCLUSIONS

FSEM-HVSD is an effective, safe, and minimally invasive treatment for ASF following colorectal cancer treatment. This technique could be the preferred treatment strategy for patients with ASF.

Endoscopic vacuum therapy and early surgical closure after pelvic anastomotic leak: meta-analysis of bowel continuity rates

BACKGROUND

Endoscopic vacuum therapy (EVT) with or without early surgical closure (ESC) is considered an effective option in the management of pelvic anastomotic leakage. This meta-analysis evaluated the effectiveness of EVT in terms of stoma reversal rate and the added value of ESC.

METHODS

A systematic search of PubMed, MEDLINE, and the Cochrane Library was conducted in November 2021 to identify articles on EVT in adult patients with pelvic anastomotic leakage. The primary outcome was restored continuity rate. Following PRISMA guidelines, a meta-analysis was undertaken using a random-effects model.

RESULTS

Twenty-nine studies were included, accounting for 827 patients with leakage who underwent EVT. There was large heterogeneity between studies in design and reported outcomes, and a high risk of bias. The overall weighted mean restored continuity rate was 66.8 (95 per cent c.i. 58.8 to 73.9) per cent. In patients undergoing EVT with ESC, the calculated restored continuity rate was 82 per cent (95 per cent c.i. 50.1 to 95.4) as compared to 64.7 per cent (95 per cent c.i. 55.7 to 72.7) after EVT without ESC. The mean number of sponge exchanges was 4 (95 per cent c.i. 2.7 to 4.6) and 9.8 (95 per cent c.i. 7.3 to 12.3), respectively. Sensitivity analysis showed a restored continuity rate of 81 per cent (95 per cent c.i. 55.8 to 99.5) for benign disease, 69.0 per cent (95 per cent c.i. 57.3 to 78.7) for colorectal cancer, and 65 per cent (95 per cent c.i. 48.8 to 79.1) if neoadjuvant radiotherapy was given.

CONCLUSION

EVT is associated with satisfactory stoma reversal rates that may be improved if it is combined with ESC.

Endoluminal vacuum-assisted therapy to treat rectal anastomotic leakage: A critical analysis

Endoluminal vacuum-assisted therapy (EVT) has been introduced recently to treat colorectal anastomotic leaks in clinically stable non-peritonitic patients. Its application has been mainly reserved to low colorectal and colo-anal anastomoses. The main advantage of this new procedure is to ensure continuous drainage of the abscess cavity, to promote and to accelerate the formation of granulation tissue resulting in a reduction of the abscess cavity. The reported results are promising allowing a higher preservation of the anastomosis when compared to conventional treatments that include trans-anastomotic tube placement, percutaneous drainage, endoscopic clipping of the anastomotic defect or stent placement. Nevertheless, despite this procedure is gaining acceptance among the surgical community, indications, inclusion criteria and definitions of success are not yet standardized and extremely heterogeneous, making it difficult to reach definitive conclusions and to ascertain which are the real benefits of this new procedure. Moreover, long-term and functional results are poorly reported. The present review is focused on critically analyzing the theoretical benefits and risks of the procedure, short- and long-term functional results and future direction in the application of EVT.
