The impact of adhesions on operations and postoperative recovery in colon cancer surgery

External Nursing Applications in the Supportive Management of Prolonged Postoperative Ileus: Description of Interventions and Case Report

Prolonged postoperative ileus is a common but clinically challenging problem that leads to patient discomfort and prolonged hospitalization; the condition is managed through a multimodular program of supportive measures. In anthroposophic nursing, the management of prolonged postoperative ileus involves additional tools, including external abdominal compresses and massages with plant or silver-containing oils and ointments. We describe 3 typical techniques: Oxalis tincture compresses, Thuja/Argentum ointment compresses, and massage with "Wala Melissenöl" (containing Melissa officinalis, Carvum cari, Foeniculum amari, and Origanum majorana). A 61-year-old man with chronic pain from adhesions after multiple abdominal surgical procedures developed a prolonged postoperative ileus after an elective ileostomy reversal. Following slow recovery during the first postoperative days, he began vomiting. A nasogastric tube was inserted, and daily Oxalis tincture compresses and massage with "Wala Melissenöl" and Thuja/Argentum ointment compresses were applied on the abdomen. The patient's symptoms gradually improved over the next 10 days. No prokinetic medications were needed to manage this episode. External abdominal nursing applications with plant substances and silver can be an additional tool in the management of prolonged postoperative ileus.

Epidemiology and Prevention of Postsurgical Adhesions Revisited

OBJECTIVE

To provide a comprehensive review of recent epidemiologic data on the burden of adhesion-related complications and adhesion prevention. Second, we elaborate on economic considerations for the application of antiadhesion barriers.

BACKGROUND

Because the landmark SCAR studies elucidated the impact of adhesions on readmissions for long-term complications of abdominal surgery, adhesions are widely recognized as one of the most common causes for complications after abdominal surgery. Concurrently, interest in adhesion prevention revived and several new antiadhesion barriers were developed. Although these barriers have now been around for more than a decade, adhesion prevention is still seldom applied.

METHODS

The first part of this article is a narrative review evaluating the results of recent epidemiological studies on adhesion-related complications and adhesion prevention. In part II, these epidemiological data are translated into a cost model of adhesion-related complications and the potential cost-effectiveness of antiadhesion barriers is explored.

RESULTS

New epidemiologic data warrant a shift in our understanding of the socioeconomic burden of adhesion-related complications and the indications for adhesion prevention strategies. Increasing evidence from cohort studies and systematic reviews shows that difficulties during reoperations, rather than small bowel obstructions, account for the majority of adhesion-related morbidity. Laparoscopy and antiadhesion barriers have proven to reduce adhesion formation and related morbidity. The direct health care costs associated with treatment of adhesion-related complications within the first 5 years after surgery are $2350 following open surgery and $970 after laparoscopy. Costs are about 50% higher in fertile-age female patients. Application of an antiadhesion barriers could save between $328 and $680 after open surgery. After laparoscopy, the costs impact ranges from $82 in expenses to $63 of savings.

CONCLUSIONS

Adhesions are an important cause for long-term complications in both open and laparoscopic surgery. Adhesiolysis during reoperations seems to impact adhesion-related morbidity most. Routine application of antiadhesion barriers in open surgery is safe and cost-effective. Application of antiadhesion barriers can be cost-effective in selected cases of laparoscopy. More research is needed to develop barriers suitable for laparoscopic use.

Technique of last resort: characteristics of patients undergoing open surgery in the laparoscopic era

BACKGROUND

The utilization rates for minimally invasive colorectal resection techniques (MICR) continue to increase. In some centers MICR methods are the preferred approach, however, open methods continue to be utilized for select patients. In this study, the profile and short-term outcomes of open colorectal resection (CR) and MICR patients are determined and compared.

METHODS

A retrospective review of patients who underwent elective CR over 11 years at two institutions was performed. The MICR group contained both laparoscopic-assisted and hand-assisted cases. The past medical and surgical histories, indications, operations performed, and short-term outcomes were assessed. The Charlson co-morbidity index (CMI) was used to assess risk.

RESULTS

During the study period 1080 patients underwent CR (Open, 141; MICR, 939). As judged by the CMI, there were more high-risk patients (score ≥2) in the Open group (34.38%) versus MICR (22.11%) p = 0.0029. Significantly more open patients had prior abdominal surgery and specifically CRs (Open, 15.60% vs. MICR, 2.13%, p < 0.001). Intraoperative transfusion (Open 25.7%; MICR 6.8%, p < 0.001) and diversion (25.53 vs. 11.50%, p < 0.001) were more common in the Open group. Not surprisingly, recovery of bowel function and length of stay were longer for the Open group. The overall complication rate was also higher for the Open patients (p < 0.001).

CONCLUSION

When MICR is the procedure of choice, patients selected for Open CR are higher risk and more complex as judged by the CMI and past operative history. Not surprisingly, this translates into a longer length of stay, higher rates of transfusion, diversion, and complications. This disparity in patients undergoing CRs makes direct comparison of MICR and Open resection outcomes not reasonable.

Morbidity related to concomitant adhesions in abdominal surgery

BACKGROUND

We sought to assess the independent effect of concomitant adhesions (CAs) on patient outcome in abdominal surgery.

MATERIALS AND METHODS

Using the American College of Surgeons National Surgical Quality Improvement Program data, we created a uniform data set of all gastrectomies, enterectomies, hepatectomies, and pancreatectomies performed between 2007 and 2012 at our tertiary academic center. American College of Surgeons National Surgical Quality Improvement Program data were supplemented with additional variables (e.g., procedure complexity-relative value unit). The presence of CAs was detected using the Current Procedural Terminology codes for adhesiolysis (44005, 44180, 50715, 58660, and 58740). Cases where adhesiolysis was the primary procedure (e.g., bowel obstruction) were excluded. Multivariable logistic regression analyses were performed to assess the independent effect of CAs on 30-d morbidity and mortality, while controlling for age, comorbidities and the type/complexity/approach/emergency nature of surgery.

RESULTS

Adhesiolysis was performed in 875 of 5940 operations (14.7%). Operations with CAs were longer (median duration 3.2 versus 2.7 h, P < 0.001), more complex (median relative value unit 37.5 versus 33.4, P < 0.001), performed in sicker patients (American Society for Anesthesiologists class ≥3 in 49.9% versus 41.2%, P < 0.001), and harbored higher risk for inadvertent enterotomies (3.0% versus 0.9%, P < 0.001). In multivariable analyses, CAs independently predicted higher morbidity (adjusted odds ratio [OR], 1.35; 95% confidence interval, 1.13-1.61, P = 0.001). Specifically, CAs independently correlated with superficial and deep or organ-space surgical site infections (OR = 1.42 (1.02-1.86), P = 0.036; OR = 1.47 (1.09-1.99), P = 0.013, respectively), and prolonged postoperative hospital stay (≥7 d, OR = 1.34 [1.11-1.61], P = 0.002). No difference in 30-d mortality was detected.

CONCLUSIONS

CAs significantly increase morbidity in abdominal surgery. Risk adjusting for the presence of adhesions is crucial in any efforts aimed at quality assessment and/or benchmarking of abdominal surgery.
