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 meg-lumine 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 abdo-minal 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 signi-ficantly 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.

A prospective randomized trial of transnasal ileus tube vs nasogastric tube for adhesive small bowel obstruction

AIM:To study the therapeutic efficacy of a new transnasal ileus tube advanced endoscopically for adhesive small bowel obstruction.METHODS:A total of 186 patients with adhesive small bowel obstruction treated from September 2007 to February 2011 were enrolled into this prospective randomized controlled study.The endoscopically advanced new ileus tube was used for gastrointestinal decompression in 96 patients and ordinary nasogastric tube(NGT) was used in 90 patients.The therapeutic efficacy was compared between the two groups.RESULTS:Compared with the NGT group,the ileus tube group experienced significantly shorter time for relief of clinical symptoms and improvement in the findings of abdominal radiograph(4.1 ± 2.3 d vs 8.5 ± 5.0 d) and laboratory tests(P < 0.01).The overall effectiveness rate was up to 89.6% in the ileus tube group and 46.7% in the NGT group(P < 0.01).And 10.4% of the patients in the ileus tube group and 53.3% of the NGT group underwent surgery.For recurrent adhesive bowel obstruction,ileus tube was also significantly more effective than NGT(95.8% vs 31.6%).In the ileus tube group,the drainage output on the first day and the length of hospital stay were significantly different depending on the treatment success or failure(P < 0.05).The abdominal radiographic improvement was correlated with whether or not the patient underwent surgery.CONCLUSION:Ileus tube can be used for adhesive small bowel obstruction.Endoscopic placement of the ileus tube is convenient and worthy to be promoted despite the potential risks.

Metal stent combined with ileus drainage tube for the treatment of delayed rectal perforation: A case report

BACKGROUND Acute iatrogenic colorectal perforation(AICP)is a serious adverse event,and immediate AICP usually requires early endoscopic closure.Immediate surgical repair is required if the perforation is large,the endoscopic closure fails,or the patient's clinical condition deteriorates.In cases of delayed AICP(>4 h),surgical repair or enterostomy is usually performed,but delayed rectal perforation is rare.CASE SUMMARY A 53-year-old male patient underwent endoscopic submucosal dissection(ESD)at a local hospital for the treatment of a laterally spreading tumor of the rectum,and the wound was closed by an endoscopist using a purse-string suture.Unfortunately,the patient then presented with delayed rectal perforation(6 h after ESD).The surgeons at the local hospital attempted to treat the perforation and wound surface using transrectal endoscopic microsurgery(TEM);however,the perforation worsened and became enlarged,multiple injuries to the mucosa around the perforation and partial tearing of the rectal mucosa occurred,and the internal anal sphincter was damaged.As a result,the perforation became more complicated.Due to the increased bleeding,surgical treatment with suturing could not be performed using TEM.Therefore,the patient was sent to our medical center for follow-up treatment.After a multidisciplinary discussion,we believed that the patient should undergo an enterostomy.However,the patient strongly refused this treatment plan.Because the position of the rectal perforation was relatively low and the intestine had been adequately prepared,we attempted to treat the complicated delayed rectal perforation using a self-expanding covered mental stent(SECMS)in combination with a transanal ileus drainage tube(TIDT).CONCLUSION For patients with complicated delayed perforation in the lower rectum and adequate intestinal preparation,a SECMS combined with a TIDT can be used and may result in very good outcomes.

Comparison of decompression tubes with metallic stents for the management of right-sided malignant colonic obstruction

BACKGROUND Emergency surgical resection is a standard treatment for right-sided malignant colonic obstruction; however, the procedure is associated with high rates of mortality and morbidity. Although a bridge to surgery can be created to obviate the need for emergency surgery, its effects on long-term outcomes and the most practical management strategies for right-sided malignant colonic obstruction remain unclear.AIM To determine the appropriate management approach for right-sided malignant colonic obstruction.METHODS Forty patients with right-sided malignant colonic obstruction who underwent curative resection from January 2007 to April 2017 were included in the study.We compared the perioperative and long-term outcomes of patients who received bridges to surgery established using decompression tubes and those created using self-expandable metallic stents(SEMS). The primary outcome was the overall survival duration(OS) and the secondary endpoints were the diseasefree survival(DFS) duration and the preoperative and postoperative morbidity rates. Analysis was performed on an intention-to-treat basis.RESULTS There were 21 patients in the decompression tube group and 19 in the SEMS group. There were no significant differences in the perioperative morbidity rates of the two groups. The OS rate was significantly higher in the decompression tube group than in the SEMS group(5-year OS rate; decompression tube 79.5%,SEMS 32%, P = 0.043). Multivariate analysis revealed that the bridge to surgery using a decompression tube was significantly associated with the OS(hazard ratio, 17.41; P = 0.004). The 3-year DFS rate was significantly higher in thedecompression tube group than in the SEMS group(68.9% vs 45.9%; log-rank test,P = 0.032). A propensity score–adjusted analysis also demonstrated that the prognosis was significantly better in the decompression tube group than in the SEMS group.CONCLUSION The bridge to surgery using trans-nasal and trans-anal decompression tubes for right-sided malignant colonic obstruction is safe and may improve long-term outcomes.

A case of postoperative recurrent intussusception associated with indwelling bowel tube

Intussusception is quite uncommon in adults.We report a rare case of a 76-year-old man with small bowel intussusception induced by two indwelling bowel tubes,the first a jejunal feeding tube and the second an ileus tube.After complete reduction of the first intussusception caused by the jejunal feeding tube and adhesion,reintussusception occurred due to the postoperative adhesion and ileus tube inserted into the bowel after the previous operation for intussusception.Finally,the part of the jejunum with re-intussusception and adhesion,including the place where the previous reduced intussusception had occurred,was resected.This case is a reminder that when there is no mucosal lesion other than an indwelling bowel tube or a hard adhesion/ inflammation around intussusception,the patient should be operated on without delay for resection of the intussusception to prevent re-intussusception,even if the resected bowel is predicted to be long.
