Effect of Acupuncture and Biofeedback on Fecal Incontinence after Anus Preservation Operation for Rectal Cancer / 中国康复理论与实践

Objective:To investigate the effect of acupuncture and biofeedback on the recovery of fecal incontinence after anus preservation operation for rectal cancer. Methods:From January 1st, 2016 to June 30th, a total of 226 patients with rectal cancer after anus preservation operation were selected. Finally, 120 patients with fecal incontinence were randomly divided into control group (n = 40), acupuncture group (n = 40) and observation group (n = 40). All the groups accepted levator ani movement. In addition, the acupuncture group received acupuncture, and the observation group received acupuncture and biofeedback, for three months. Cleveland Clinic Florida Faecal Incontinence Scores (CCF-FIS), anorectal pressure, pelvic floor surface electromyography and quality of life were measured before treatment, and one month, two months and three months after treatment. Results:There was no significant difference in CCF-FIS, anorectal pressure, pelvic floor surface electromyography and quality of life among three groups before treatment (F < 2.943, P > 0.05). After treatment, all the above indexes improved (F > 5.235, P < 0.01), and were better in the acupuncture group and observation group than in the control group (P < 0.05), especially in the observation group (P < 0.05) at each time point. The curative effect of the observation group was related to the location of the tumor (χ2 > 4.405, P < 0.05) one month after treatment, and it was related to whether pelvic autonomic nerve preservation was performed during the operation (χ2 > 4.706, P < 0.05) and whether radiotherapy was added after the operation (χ2 > 5.013, P < 0.05) at each time point after treatment. At three months follow-up, the recurrence rate was lower in the observation group (8.6%) than in the acupuncture group (35.7%) and in the control group (35.0%) (χ2 > 5.976, P < 0.05). No complication occurred in all groups. Conclusion:Acupuncture and biofeedback can improve the symptoms of defecation incontinence and promote the recovery of anal function after anus preservation operation for rectal cancer.

Giant chylous cyst and ileal duplication in a young adult

Alimentary tract duplications are rare congenital anomalies that usually present in childhood and occasionally in adults. They are most common in the ileum, but can occur anywhere along the alimentary tract from the mouth to the anus. We report a 24-year-old woman who presented with a giant chylous ileum cyst duplication. To our knowledge, there is only one other report of a patient with a giant chylous cyst in the literature.

Laparoscopic surgery of gastric gastrointestinal stromal tumor / 中华胃肠外科杂志

Gastric gastrointestinal stromal tumor(GIST) is the most common mesenchymal neoplasms of the gastro-intestinal tract.For its unique biological behavior with KIT gene expression and the particular clinical characteristics with the recurrent nature, surgery and molecular targeted therapy is the main treatment of gastric GIST. Laparoscopic technology has been used in the surgical treatment of gastric GIST and is the future trend. In this article, we shed some light on the standardize surgical procedures of radical laparoscopic gastrectomy, obeying the surgical principles, accurate intraoperative localization, and surgery combined with targeted therapy.

<p><b>OBJECTIVE</b>The authors report the newly developed reconstruction technique after laparoscopic total gastrectomy (LTG) or laparoscopic distal gastrectomy (LDG): intracorporeal circular stapling esophagojejunostomy(esophagojejunostomy) using the reverse puncture device(RPD).</p><p><b>METHODS</b>After LTG or LDG, The anvil is then transorally inserted into the esophagus by using the RPD system. Double-stapling esophagojejunostomy with a circular stapler is performed intracorporeally, and the jejunal stump is closed with an Echelon.</p><p><b>RESULTS</b>There was no intraoperative complication or conversion to open surgery, the mean operation time was 155 min and blood loss was 75 ml. Postoperative fluorography revealed no anastomosis leakage or stenosis Patients resumed an oral liquid diet on postoperative day 2, and discharged at day 8.</p><p><b>CONCLUSIONS</b>We have successfully performed LTG or LDG, reconstruction using our technique in 18 patients without any anastomosis complications. We believe that our procedure is a safe and reliable reconstruction method, which is especially useful in obese patients, in whom conventional extracorporeal anastomosis is often difficult.</p>

Effects of duodenal-jejunal bypass and sleeve gastrectomy on the expression of liver glucokinase in diabetic rats / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To investigate the effects of duodenal-jejunal bypass(DJB) and sleeve gastrectomy(SG) on the expression of liver glucokinase(GCK) in diabetic rats.</p><p><b>METHODS</b>Animal models of Goto-Kakizaki rats and Sprague-Dawley rats were established by DJB and SG. Results of fasting glycemia and insulin were compared. Liver tissue was harvested 8 weeks postoperatively.Quantitative real-time PCR and Western blot were used to detect liver GCK mRNA and protein expression after operation.</p><p><b>RESULTS</b>Fasting plasma glucose levels of DJB group and SG group in GK rats were markedly declined 3 day and 1, 2, 4, 6, 8 weeks postoperatively(all P <0.01), while Sham group only dropped 3 day and 1 week postoperatively, and there were no significant differences 2 weeks postoperatively(P >0.05). Fasting plasma glucose levels of each group in SD rats did not change after operation. In GK rats, GCK mRNA level (1.45 +/-0.29) and protein expression (494.25 +/-30.25) after DJB were higher than Sham group (1.05 +/-0.19 and 409.13 +/-26.86) and control group (1.04 +/-0.17 and 404.75 +/-30.90). GCK mRNA level and protein expression after SG were 0.65 +/-0.25 and 345.25 +/-28.13 respectively, which were significantly lower than those in control group(all P <0.01). All the groups in SD rats experienced similar GCK expression change.</p><p><b>CONCLUSION</b>Both DJB and SG can decrease the plasma glucose levels of GK rats, while there are different effects on the expression of liver GCK.</p>

Efficacy of sleeve gastrectomy plus gastric remnant banding on weight reduction and remnant gastric dilatation: an animal experimental study / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To investigate the efficacy of sleeve gastrectomy plus gastric remnant banding on weight reduction and remnant gastric dilatation in SD rat model.</p><p><b>METHODS</b>Sleeve gastrectomy plus gastric remnant banding was performed in 20 male SD rats as the study group; sleeve gastrectomy was performed in 20 SD male rats as the control group, and laparotomy was performed in 10 SD male rats as the blank control group. Body weight was measured before the experiment, at day 1 and at 2-week intervals within 16 weeks after operation.</p><p><b>RESULTS</b>The number of survival rats was 15 in the study group (15/20), 13 in the control group (13/20), and 10 in the blank control group (10/10). Postoperative body weight increased markedly in the blank control group, returned to the pre-operative level two weeks after operation in the control group, and four weeks after operation in the study group. Weight increase of the study group was significantly slower than that of the other two groups (P<0.01). Postoperative gastric dilation of the control group was more obvious as compared to the study group.</p><p><b>CONCLUSION</b>Sleeve gastrectomy plus gastric remnant banding is safe and effective because of the restriction of postoperative gastric dilation.</p>

Laparoscopic resection of submucosal tumors in gastric fundus / 中华外科杂志

<p><b>OBJECTIVE</b>To investigate the feasibility and safety of extraluminal laparoscopic wedge resection (ELWR) in treating submucosal tumors in the gastric fundus.</p><p><b>METHODS</b>Clinical data of 84 patients underwent ELWR for submucosal tumors in the gastric fundus between September 2000 and December 2006 were reviewed and analyzed retrospectively. The four-portal operation procedures were carried out as follows: localization of the tumor, dissection of the omentum, mobilization of the gastric fundus and the upper polar of spleen, exposure of ECJ, and resection of the gastric fundus with Endo GIA.</p><p><b>RESULTS</b>The patients included 53 males and 31 females, age ranged from 32 to 78 years (mean, 59 years). The mean tumor diameter was (4.2 +/- 1.3) cm. The distance from the tumor edge to the ECJ was 1.1 - 3.0 cm. The operations were successful in all the 84 patients, with a mean operation time of (62.6 +/- 8.9) min and mean operative blood loss of (86.2 +/- 8.1) ml. No apparent tumor focus was left. No operation was converted to open surgery, and no significant postoperative complications occurred. The mean post-operative hospital stay was (5.6 +/- 0.5) days. The gastrointestinal function recovered within 36 h after operation in 66 cases (78.6%), and the patients returned to normal activity and restored oral feeding. The distance between the tumor and the resection margin was 0.7 - 2.5 cm from the ECJ [mean, (1.4 +/- 0.5) cm], and 2.5 - 6.0 cm from the other three sides [mean, (4.1 +/- 1.0) cm]. Of the 84 cases, 29 cases were diagnosed with leiomyoma, 51 cases different types of stromal tumor and 4 cases neurofibroma. The mean follow-up duration was (51.0 +/- 4.3) months, no recurrence or metastasis was found in the mean time.</p><p><b>CONCLUSIONS</b>ELWR is a safe, simple and beneficial procedure for submucosal tumors in the gastric fundus, especially in the posterior wall near the ECJ. It avoids intraperitoneal infection, possible splenic injury and postoperative esophageal stenosis. In addition, the resection scope is not limited.</p>
