Intraoperative maneuvers may affect the development of early postoperative small bowel obstruction after laparoscopic colorectal cancer surgery: Multicenter prospective cohort study

Efficacy of ileus tube combined with meglumine diatrizoate in treating postoperative inflammatory bowel obstruction after surgery

BACKGROUND

Early postoperative inflammatory small bowel obstruction (EPISBO) is easy to be complicated after colorectal cancer surgery. Both intestinal obstruction catheter and meglumine can treat EPISBO.

AIM

To investigate the efficacy of an intestinal obstruction tube combined with meglumine diazo in treating EPISBO of colorectal cancer.

METHODS

Data from 60 patients with colorectal cancer and intestinal obstruction admitted to the Proctology Department of our hospital from April 2018 to May 2022 were collected and analyzed and divided into three cohorts according to different treatment regimens. Cohort A (n = 20) received a transnasal intestinal obstruction catheter with panumglumine, and cohort B (n = 20) received a transnasal intestinal obstruction catheter with liquid paraffin. Cohort C (n = 20) received oral treatment with meglumine. The clinical efficacy, first exhaust/defecation time, length of hospital stay, gastrointestinal decompression time, relief time of abdominal pain, and relief time of abdominal distension were compared among the three cohorts. The levels of C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), monocyte chemotactic protein-1 (MCP-1), serum albumin, and transferrin were compared among the three cohorts before and after treatment. The occurrence of adverse reactions in the three cohorts was compared.

RESULTS

Compared with cohort C, the successful treatment rate of cohort A was significantly higher. There were statistically significant variations in the time of first exhaust/defecation, length of hospital stays, gastrointestinal decompression time, relief time of abdominal pain, and relief time of abdominal distention among the three cohorts. Compared with cohort C, cohort A's first exhaust/defecation time, hospitalization time, gastrointestinal decompression time, abdominal pain relief time, and abdominal distension relief time was reduced (P < 0.05). After treatment, serum CRP, TNF-α, IL-6, and MCP-1 expression levels increased, and serum albumin and serum transferrin levels increased in the three cohorts. The serum albumin level in cohort A was higher than in cohort C. Compared with cohort B and cohort C, the serum transferrin level in cohort A increased (P < 0.05). Compared with cohort C, the total incidence of adverse reactions in cohorts A and B was significantly higher (P < 0.05). The incidence of adverse reactions was similar between cohort A and cohort B.

CONCLUSION

Using an ileus tube combined with meglumine diatrizoate can effectively treat postoperative inflammatory ileus obstructions after surgery colorectal cancer and improve prognosis, inflammatory response, and nutritional status.

Efficacy of Daikenchuto in the prevention of bowel obstruction in patients with colorectal cancer undergoing laparoscopic surgery: An observational study using a Japanese administrative claims database

PURPOSE

Daikenchuto is an herbal medicine widely used in Japan without clear evidence to prevent bowel obstruction after abdominal surgery. We evaluated the efficacy of Daikenchuto in laparoscopic surgery for colorectal cancer (CRC).

METHODS

We included patients from the medical claims databases diagnosed with CRC between January 2012 and December 2019 and treated with laparoscopic surgery. We compared the Daikenchuto and control groups to evaluate early bowel obstruction (EBO) events for 1 year. The Daikenchuto group included patients prescribed Daikenchuto on postoperative day (POD) 0 or 1. An EBO event was defined as the use of a nasogastric tube, transnasal ileus tube, endoscopic balloon dilatation, or the requirement of reoperation for bowel obstruction from PODs 1 to 364.

RESULTS

In total, 46,458 patients met the eligibility criteria; 2407 and 44,051 patients were included in the Daikenchuto and control groups, respectively. Some of the patient's characteristics were significantly different between the groups. The frequencies of EBO events in the Daikenchuto and control groups were 5.7% (95% confidence interval: 4.8-6.7) and 4.6% (4.4-4.8), respectively. The most frequent events were nasogastric tube (3.1%, 2.9%) and transnasal ileus tube insertions (1.4%, 0.8%) in the Daikenchuto and control groups, respectively. The hospital stay was significantly shorter in the Daikenchuto group than in the control; this trend was confirmed in the sensitivity analysis.

CONCLUSIONS

Daikenchuto did not demonstrate efficacy for EBO. It might be adequate for shortening patient's hospital stay. Further studies are warranted.

Diagnosis, Treatment, and Prevention of Ileostomy Complications: An Updated Review

An ileostomy is associated with multiple complications that may frequently or persistently affect the life of ostomates. All healthcare professionals should have knowledge of the diagnosis, treatment, and prevention of ileostomy complications. Peristomal dermatitis is caused by watery and highly alkaline effluent. Skin protective products are typically used for local treatment. Ischemia/necrosis occurs due to insufficient arterial blood supply. Retraction is seen in patients with a bulky mesentery and occurs following ischemia. Convex stoma appliances can be used for skin protection against fecal leakage. Small bowel obstruction (SBO) is common and occurs only at the stoma site. Trans-stomal decompression is most effective in these cases. High output stoma (HOS) is defined as a condition when the output exceeds 1,000- 2,000 ml/day, lasting for one to three days. Treatment includes intravenous fluid and electrolyte resuscitation followed by restriction of hypotonic fluid and the use of antimotility (and antisecretory) drugs. Stomal prolapse is a full-thickness protrusion of an inverted bowel. Manual reduction is attempted initially, whereas emergency bowel resection may be needed for incarcerated cases. A parastomal hernia (PSH) is an incisional hernia of the stoma site. Surgery is considered in cases of incarceration, but most cases are manageable with non-surgical treatment.

High visceral to subcutaneous fat area ratio predicts early postoperative small bowel obstruction after surgery for colorectal cancer

PURPOSE

Risks for postoperative small bowel obstruction have been demonstrated in several reports, most of which indicated male sex was a risk factor, but with the reason remaining unknown. We tested the hypothesis that it could be because males have more visceral fat than females. This prospective observational study aims to examine risks of early postoperative small bowel obstruction (EPSBO) after colorectal cancer surgery and the association between visceral to subcutaneous fat area ratio (V/S ratio) and EPSBO.

METHODS

Four hundred and seventy-four patients who underwent colectomy for colorectal cancer in our hospital were enrolled in this study. The influence of several factors including V/S ratio on the development of EPSBO was analyzed.

RESULTS

Thirty-one of the 474 patients (6.5%) developed EPSBO. EPSBO occurred more frequently in males (p = 0.03) and cases who developed postoperative anastomotic leakage (p < 0.001) or wound infection (p = 0.02). Higher V/S ratio was strongly related to male sex (p < 0.001). Multivariate analysis revealed higher V/S ratio (OR 2.25; p = 0.049) and anastomotic leakage (OR 5.86; p < 0.001) were independent risk factors for EPSBO.

CONCLUSION

Higher V/S ratio was significantly related to EPSBO, suggesting that one of the reasons EPSBO was more likely to occur in males because they have more visceral fat than females. Preoperative identification of this risk factor could help us watch out for this potential complication.

Novel nomogram for predicting risk of early postoperative small bowel obstruction after right colectomy for cancer

Background

Early postoperative small bowel obstruction (EPSBO) is a common complication after colorectal cancer surgery. Few studies have specifically studied risk factors for early small bowel obstruction after right colectomy, especially in establishing predictive models. The purpose of the current study was to establish an effective nomogram to predict the incidence of EPSBO after right colectomy.

Methods

The current study retrospectively analyzed data from a total of 424 patients who underwent right colectomy in a local hospital from January 2014 to March 2021. A logistic regression model was used to identify potential risk factors for EPSBO after right colectomy. A nomogram was established by independent risk factors, and the prediction performance of the model was evaluated using an area under the receiver operating characteristic (ROC) curve and calibration chart.

Results

A total of 45 patients (10.6%) developed early small bowel obstruction after right colectomy. Male sex, history of abdominal surgery, open surgery, long operative time, anastomotic leakage, and preoperative albumin were closely related to EPSBO. Analysis of postoperative rehabilitation indices showed that EPSBO remarkably slowed the postoperative rehabilitation speed of patients. Multivariate logistic regression analysis showed that male sex, open surgery, operative time, and anastomotic leakage were independent risk factors (P < 0.05), and the operation time had the greatest impact on EPSBO. On the basis of multivariate logistic regression, a nomogram was constructed, which showed moderate accuracy in predicting EPSBO, with a C-statistic of 0.716. The calibration chart showed good consistency between the predicted probability and ideal probability.

Conclusion

The current study constructed a nomogram based on the clinical data of patients who underwent right colectomy, which had moderate predictability and could provide reference value for clinicians to evaluate the risk of EPSBO.
