Elective Bowel Surgery with or without Prophylactic Nasogastric Decompression: A Prospective, Randomized Trial

Nurse-delivered acupressure on early postoperative gastrointestinal function among patients undergoing colorectal cancer surgery

Objective

Postoperative gastrointestinal dysfunction occurred up to 25% of patients who undergo colorectal cancer surgery, which could cause severe complications and increase economic burden. This study aims to evaluate the effectiveness of nurse-delivered acupressure on early postoperative gastrointestinal function among patients undergoing colorectal cancer surgery.

Methods

A total of 112 adult patients (≥ 18 years) scheduled to receive colorectal cancer surgery were randomized into two groups. Acupressure was practiced at ST36 for five days after operation, while the control group used gently rubbing skin. Primary outcomes were the time to first passage of flatus and defecation, while the secondary outcomes were the degree of abdominal distention and bowel motility. The Student's t-test and Mann-Whitney U test or Chi-square test and regression analyses were used, while for repeated measures of outcomes, area under the curve (AUC) was compared between groups and subgroups.

Results

After adjusting for potential confounding variables, acupressure significantly shortened the time to have first flatus passage by 11.08 ​h (95%CI: -19.36 to -2.81; P ​< ​0.01). The first passage time of defecation (mean, 77.00 ​± ​36.27 ​h vs. 80.08 ​± ​28.88 ​h), abdominal distention (AUC, 5.68 ​± ​5.24 vs. 5.92 ​± ​4.03), and bowel motility (AUC, 12.09 ​± ​4.70 vs. 11.51 ​± ​3.00) in the intervention group had some improvement although the differences were not statistically significant (P ​> ​0.05).

Conclusions

This study indicated that acupressure done by trained nurses could be an effective and feasible solution to promote early gastrointestinal function recovery among patients undergoing colorectal cancer surgery.

Enhancing recovery after minimally invasive surgery in children: A systematic review of the literature and meta-analysis

OBJECTIVE

Enhanced recovery after surgery (ERAS) has been widely implemented after minimally invasive surgeries (MIS) in adults. The aim of this study was to evaluate the current evidence available on ERAS after MIS in children.

METHODS

Using a defined search strategy (PubMed, Cochrane, Scopus), we performed a systematic review of the literature, searching for studies reporting on ERAS after MIS (thoracoscopy, laparoscopy, retroperitoneoscopy) in children (1975-2019). This study was registered with PROSPERO-international prospective register of systematic reviews. A meta-analysis was conducted using comparative studies for length of stay (LOS), complication rates, and readmission rates.

RESULTS

Of 180 abstracts screened, 20 full-text articles were analyzed, and 9 were included in our systematic review (1 randomized controlled trial, 3 prospective, and 5 retrospective studies), involving a total number of 531 patients. ERAS has been applied to laparoscopy for digestive (n = 7 studies) or urologic surgeries (n = 1), as well as thoracoscopy (n = 1). Mean LOS was decreased in ERAS children compared to controls (6 studies, -1.12 days, 95%IC: -1.5 to -0.82, p < 0.00001). There was no difference in complication rates between ERAS children and control children (5 studies, 13% vs 14%, OR = 0.84, 95%CI: 0.49-1.44, p = 0.52). The 30-day readmission rate was decreased in ERAS children compared to controls (6 studies, 4% vs 10%, OR = 0.34, 95%CI: 0.18-0.66, p = 0.001).

CONCLUSIONS

Although the evidence regarding ERAS in MIS is scarce, these protocols seem safe and effective, by decreasing LOS and 30-day readmission rate, without increasing post-operative complication rates.

Enhanced Recovery After Surgery: Are Benefits Demonstrated in International Studies Replicable in Pakistan?

Objectives

To determine the efficacy of enhanced recovery after surgery (ERAS) protocols in terms of frequency of surgical site infection (SSI) and length of hospital stay in patients undergoing colorectal surgeries for colorectal carcinoma.

Study design

Quasi-experimental study.

Setting/Duration of study

Department of Surgery, Shifa International Hospital, Islamabad, from May 7, 2019 to November 6, 2019.

Methodology

A total of 120 patients with colorectal carcinomas who fulfilled that sample selection criteria were studied. After randomization, patients were divided into two equal groups; one group received management under ERAS while the second group received conventional management. All patients were recorded for length of hospital stay and the development of SSIs. Data were analyzed using SPSS 26.0.

Results

The mean age was 42.34 ± 14.45 years, with a male majority, i.e., 72 (60%). The mean duration of in-patient stay was 3.45 ± 1.73 days with ERAS and 8.25 ± 1.58 days with conventional management (p < 0.001). A total of 28 (23.3%) SSIs developed, of which nine (7.5%) SSIs occurred with ERAS, while 19 (15.8%) occurred with traditional management (p = 0.031).

Conclusion

ERAS protocols have been demonstrated to be effective, cheap, and safe. There is a tangible reduction in length of hospital stay and incidence of SSIs which translates into reduced utilization of resources and financial costs. However, strict adherence to the protocol may be necessary to obtain the aforementioned benefits, which may be difficult to do in the face of professional, institutional, and personal inertia. Intensive efforts are required to make these protocols more convenient and attractive to implement, so as to facilitate conversion to this management approach.

Nasogastric decompression after intestinal surgery in children: a systematic review and meta-analysis

PURPOSE

Postoperative nasogastric decompression has been routinely used after intestinal surgery. However, the role of nasogastric decompression in preventing postoperative complications and promoting the recovery of bowel function in children remains controversial. This systematic review aimed to assess whether routine nasogastric decompression is necessary after intestinal surgery in children.

METHODS

A systematic review was conducted following the PRISMA guideline. Literature search was performed in electronic databases including PubMed, Embase, CENTRAL, and Web of science. Studies comparing outcomes between children who underwent intestinal surgery with postoperative nasogastric tube (NGT) placement (NGT group) and without postoperative NGT placement (no NGT group) were included.

RESULTS

Six studies were eligible for inclusion criteria including two randomized controlled trials (RCT) and four comparative observational studies. The overall rate of postoperative anastomotic leak was 0.6% (1/179) in NGT group and 0.9% (2/223) in no NGT group. The overall rate of wound dehiscence was 2.4% (4/169) in NGT group and 1.6% (4/245) in no NGT group. Meta-analysis of two RCTs in children undergoing elective intestinal surgery showed significant increase of mild vomiting in no NGT group compared with NGT group (OR 3.54 95% CI 1.04, 11.99) but no significant difference in persistent vomiting requiring NGT reinsertion (OR 3.11 95% CI 0.47, 20.54), abdominal distension (OR 2.36 95% CI 0.34, 16.59), NGT reinsertion (OR 3.11 95% CI 0.47, 20.54), wound infection (OR 1.63 95% CI 0.49, 5.48) and time to return of bowel movement (MD - 0.14 95% CI - 0.45, 0.17). There was no incidence of anastomotic leak in these 2 RCTs. However, there was an incidence of NGT-related discomfort in NGT group, which ranged from 30 to 100% of children studied.

CONCLUSION

Routine postoperative nasogastric decompression can be omitted in children undergoing intestinal surgery due to no benefit in preventing postoperative complications while increasing patient discomfort.

Application of enhanced recovery after surgery during the perioperative period in infants with Hirschsprung's disease - A multi-center randomized clinical trial

BACKGROUND & AIMS

Various enhanced recovery after surgery (ERAS) guidelines have been established for several kinds of adult surgeries. While the guidelines for pediatric surgeries remained to be explored. The aim of the study was to prospectively evaluate the safety and efficacy of an ERAS protocol for Hirschsprung's disease (HSCR) infants undergoing pull-through procedures.

METHODS

An infant-specific ERAS protocol was developed and implemented at multiple centers from June 1, 2016 to December 31, 2017. The study included 145 consecutive patients who underwent pull-through surgery for HSCR in three Children's hospitals. Patients were primarily divided into three groups based on the clinical classification and surgical methods. Group I included patients with the short segment type who received transanal endorectal pull-through (TEPT) surgery. Group II comprised of patients with the classical type and long segment type who received laparoscopic-assisted pull-through (LAPT) surgery. Group III involved patients with the long segment type (who had received ileostomy or colostomy during the neonatal period) and total colonic aganglionosis who received open pull-through (OPPT) surgery. Patients in the three groups mentioned above were randomly and equally assigned into the ERAS group and traditional (TRAD) group with random number table row randomization. The primary outcome was the length of postoperative hospital stay (LOS). Secondary outcomes of interest included white blood cell (WBC) and C-reactive protein (CRP) on postoperative day 1 (POD 1), the blood glucose at the time of anesthesia and 24 h after surgery, time to first defecation, time to regular diet, plasma markers of nutrition status on POD 5, plasma natrium on POD 5, the mean intraoperative fluid volume, time to discontinuation of intravenous infusion, incidence of postoperative complications, re-admission within 30 days, hospitalization costs, parental satisfaction, and growth from admission to 6 months after surgery.

RESULTS

73 and 75 patients were assigned to the TRAD and ERAS groups, respectively. There were no significant differences in demographic data. The LOS decreased from 9.5 days in the TRAD group to 7.9 days (P < 0.001) in the ERAS group. WBC count on POD 1 showed no significant difference between the two groups. CRP on POD 1 in the ERAS group was significantly lower (P < 0.001). In the ERAS group, the blood glucose was higher at anesthesia compared to the TRAD group (P < 0.001). On the contrary, the blood glucose at 24 h after surgery was significantly lower in the ERAS group (P < 0.001). Intraoperative fluid volume was lower in the EARS group (P < 0.001). ERAS could also reduce the time to first defecation (P < 0.001), discontinuation of intravenous infusion (P < 0.001) and regular diet (P < 0.001). In the ERAS group, the concentrations of prealbumin and retinol conjugated protein on POD 5 were higher than those in the TRAD group (P < 0.001, P < 0.001, respectively). The plasma natrium had no difference in the two groups on POD 5 (P > 0.05). The rate of complications (P > 0.05) and 30-day re-admission (P > 0.05) were not significantly different between the two groups. Hospitalization costs were also reduced (P < 0.001). ERAS group has a higher parental satisfaction rate, although there was no statistical difference (96% vs 89%). There was no difference in growth between the ERAS and the TRAD groups from admission to 6 months after the surgery (weight for age z score: P > 0.05, weight for length z score: P > 0.05). We also found that the shortening of LOS by the application of ERAS protocol was more obvious in the OPPT group (-2.5 ± 1.0) than that in the TEPT (-1.9 ± 1.3) and LAPT (-1.3 ± 0.4) groups.

CONCLUSIONS

Implementation of the ERAS protocol in infants undergoing HSCR pull-through operations is safe and efficient. The ERAS protocol is worthy of recommendation.

Postoperative ileus following major colorectal surgery

BACKGROUND

Postoperative ileus (POI) is characterized by delayed gastrointestinal recovery following surgery. Current knowledge of pathophysiology, clinical interventions and methodological challenges was reviewed to inform modern practice and future research.

METHODS

A systematic search of MEDLINE and Embase databases was performed using search terms related to ileus and colorectal surgery. All RCTs involving an intervention to prevent or reduce POI published between 1990 and 2016 were identified. Grey literature, non-full-text manuscripts, and reanalyses of previous RCTs were excluded. Eligible articles were assessed using the Cochrane tool for assessing risk of bias.

RESULTS

Of 5614 studies screened, 86 eligible articles describing 88 RCTs were identified. Current knowledge of pathophysiology acknowledges neurogenic, inflammatory and pharmacological mechanisms, but much of the evidence arises from animal studies. The most common interventions tested were chewing gum (11 trials) and early enteral feeding (11), which are safe but of unclear benefit for actively reducing POI. Others, including thoracic epidural analgesia (8), systemic lidocaine (8) and peripheral μ antagonists (5), show benefit but require further investigation for safety and cost-effectiveness.

CONCLUSION

POI is a common condition with no established definition, aetiology or treatment. According to current literature, minimally invasive surgery, protocol-driven recovery (including early feeding and opioid avoidance strategies) and measures to avoid major inflammatory events (such as anastomotic leak) offer the best chances of reducing POI.
