Vertical distance from navel as a risk factor for bowel obstruction associated with feeding jejunostomy after esophagectomy: a retrospective cohort study

Benefit of a laparoscopic jejunostomy feeding catheter insertion to prevent bowel obstruction associated with feeding jejunostomy after esophagectomy

The placement of a jejunostomy catheter during esophagectomy may cause postoperative bowel obstruction. The proximity of the jejunostomy site to the midline might be associated with bowel obstruction, and we have introduced laparoscopic jejunostomy (Lap-J) to reduce jejunostomy's left lateral gap. We evaluated 92 patients who underwent esophagectomy for esophageal cancer between February 2013 and August 2022 to clarify the benefits of Lap-J compared to other methods. The patients were classified into two groups according to the method of feeding catheter insertion: jejunostomy via small laparotomy (J group, n = 75), and laparoscopic jejunostomy (Lap-J group, n = 17). Surgery for bowel obstruction associated with the feeding jejunostomy catheter (BOFJ) was performed on 11 in the J group. Comparing the J and Lap-J groups, the distance between the jejunostomy and midline was significantly longer in the Lap-J group (50 mm vs. 102 mm; P < 0.001). Regarding surgery for BOFJ, the distance between the jejunostomy and midline was significantly shorter in the surgery group than in the non-surgery group (43 mm vs. 52 mm; P = 0.049). During esophagectomy, Lap-J can prevent BOFJ by placing the jejunostomy site at the left lateral position to the midline and reducing the left lateral gap of the jejunostomy.

A clinical nomogram for predicting small bowel obstruction after extubation after radical resection of esophageal cancer and jejunostomy

BACKGROUND

Small bowel obstruction after extubation is among the most serious complications of radical esophageal cancer and jejunostomy resection. This study aimed to explore the risk factors and treatment methods for small bowel obstruction after extubation and construct a predictive model to guide its clinical management.

METHODS

Clinical data for 514 patients who underwent esophagectomy with jejunostomy for esophageal cancer were collected. A nomogram was constructed using the independent risk factors for small bowel obstruction after extubation determined on multivariable logistic regression analysis, and a subgroup analysis was performed of the treatment methods for the 61 patients with small bowel obstruction after extubation.

RESULTS

The nomogram incorporated the independent risk factors for small bowel obstruction after extubation (gastrointestinal function recovery [P < .001], postoperative albumin reduction ratio [P = .009], and serious postoperative complications [P < .001]) in the multivariable logistic regression analysis. The final model had an area under the curve of 0.829 (95% confidence interval, 0.775-0.883). The calibration plots demonstrated high concordance between the predicted and actual probabilities. The model demonstrated excellent discriminatory power for internal and time validation, with adjusted C-statistics of 0.821 and 0.810 (95% confidence interval, 0.686-0.933), respectively. In the subgroup analysis, an abnormal anion gap (P = .016) and low serum albumin level (P = .005) were associated with recurrent small bowel obstruction. The model's area under the curve was 0.815 (95% confidence interval, 0.683-0.948). The probability of recurrence among patients with small bowel obstruction after extubation was 78.3% when the 2 risk factors were present.

CONCLUSION

The clinical nomogram based on small bowel obstruction after extubation predictors recommends aggressive surgical intervention for patients with small bowel obstruction after extubation and an abnormal anion gap and low serum albumin level at admission.

Risk factors for refractory enterocutaneous fistula following button jejunostomy removal and its treatment using a novel extraperitoneal approach in patients with oesophageal cancer: a retrospective cohort study

BACKGROUND

Enterocutaneous fistula after removal of the jejunostomy tube leads to multiple problems, such as cosmetic problems, decreased quality of life, electrolyte imbalances, infectious complications, and increased medical costs. However, the risk factors for refractory enterocutaneous fistula (REF) after button jejunostomy removal remain unclear. Therefore, in this study, we assessed the risk factors for REF after button jejunostomy removal in patients with oesophageal cancer and reported the surgical outcomes of the novel extraperitoneal approach (EPA) for REF closure.

METHODS

This retrospective cohort study included 47 patients who underwent button jejunostomy removal after oesophagectomy for oesophageal cancer. We assessed the risk factors for REF in these patients and reported the surgical outcomes of the novel EPA for REF closure at the International University of Health and Welfare Hospital between March 2013 and October 2021. The primary endpoint was defined as the occurrence of REF after removal of the button jejunostomy, which was assessed using a maintained database. The risk factors and outcomes of the EPA for REF closure were retrospectively analysed.

RESULTS

REFs occurred in 15 (31.9%) patients. In the univariate analysis, REF was significantly more common in patients with albumin level < 4.0 g/dL (p = 0.026), duration > 12 months for button jejunostomy removal (p = 0.003), and with a fistula < 15.0 mm (p = 0.002). The multivariate analysis revealed that a duration > 12 months for button jejunostomy removal (odds ratio [OR]: 7.15; 95% confidence interval [CI]: 1.38-36.8; p = 0.019) and fistula < 15.0 mm (OR: 8.08; 95% CI: 1.50-43.6; p = 0.002) were independent risk factors for REF. EPA for REF closure was performed in 15 patients. The technical success rate of EPA was 88.2%. Of the 15 EPA procedures, fistula closure was achieved in 12 (80.0%). The complications of EPA (11.7%) were major leakages (n = 3) and for two of them, EPA procedure was re-performed, and closure of the fistula was finally achieved.

CONCLUSION

This study suggested that duration > 12 months for button jejunostomy removal and fistula < 15.0 mm are the independent risk factors for REF after button jejunostomy removal. EPA for REF closure is a novel, simple, and useful surgical option for patients with REF after oesophagectomy.

Implementation of the Esophagectomy Complication Consensus Group definitions: the benefits of speaking the same language

In 2015 the Esophagectomy Complication Consensus Group (ECCG) reported consensus definitions for complications after esophagectomy. This aimed to reduce variation in complication reporting, attributed to heterogeneous definitions. This systematic review aimed to describe the implementation of this definition set, including the effect on complication frequency and variation. A systematic literature review was performed, identifying all observational and randomized studies reporting complication frequencies after esophagectomy since the ECCG publication. Recruitment periods before and subsequent to the index ECCG publication date were included. Coefficients of variance were calculated to assess outcome heterogeneity. Of 144 studies which met inclusion criteria, 70 (48.6%) used ECCG definitions. The median number of separately reported complication types was five per study; only one study reported all ECCG complications. The coefficients of variance of the reported frequencies of eight of the 10 most common complications were reduced in studies which used the ECCG definitions compared with those that did not (P = 0.036). Among ECCG studies, the frequencies of postoperative pneumothorax, reintubation, and pulmonary emboli were significantly reduced in 2020-2021, compared with 2015-2019 (P = 0.006, 0.034, and 0.037 respectively). The ECCG definition set has reduced variation in esophagectomy morbidity reporting. This adds greater confidence to the observed gradual improvement in outcomes with time, and its ongoing use and wider dissemination should be encouraged. However, only a handful of outcomes are widely reported, and only rarely is it used in its entirety.
