Long-term follow-up of the Jinling procedure for combined slow-transit constipation and obstructive defecation

Usefulness of Deloyers procedure with minimally invasive coloproctectomy in an elderly patient with synchronous colorectal cancer: A case report

Subtotal colectomy is often performed on patients with synchronous colorectal cancer. However, compared with colorectal anastomosis, ileorectal anastomosis with subtotal colectomy is more likely to result in bowel dysfunction. The Deloyers procedure is useful in preserving bowel function in a patient with synchronous colorectal cancer. An 87-year-old man presented with bloody stool. Colonoscopy showed masses in the cecum, transverse colon, rectosigmoid, and rectum above the peritoneal reflection. Computed tomography scan revealed no evidence of regional lymph node swelling and distant metastasis. Therefore, robot-assisted low anterior resection, laparoscopic extended left hemicolectomy, laparoscopic cecal resection, and diverting ileostomy were performed. The patient was discharged from the hospital without complications. There was no recurrence, and the patient did not have complaints such as urgency, fecal incontinence, and excretory dysfunction. Hence, minimally invasive coloproctectomy using the Deloyers procedure can be safe and useful in preserving postoperative bowel function in elderly patients.

A Shigella species variant is causally linked to intractable functional constipation

Intractable functional constipation (IFC) is the most severe form of constipation, but its etiology has long been unknown. We hypothesized that IFC is caused by refractory infection by a pathogenic bacterium. Here, we isolated from patients with IFC a Shigella species - peristaltic contraction-inhibiting bacterium (PIB) - that significantly inhibited peristaltic contraction of the colon by production of docosapentenoic acid (DPA). PIB colonized mice for at least 6 months. Oral administration of PIB was sufficient to induce constipation, which was reversed by PIB-specific phages. A mutated PIB with reduced DPA was incapable of inhibiting colonic function and inducing constipation, suggesting that DPA produced by PIB was the key mediator of the genesis of constipation. PIBs were detected in stools of 56% (38 of 68) of the IFC patients, but not in those of non-IFC or healthy individuals (0 of 180). DPA levels in stools were elevated in 44.12% (30 of 68) of the IFC patients but none of the healthy volunteers (0 of 97). Our results suggest that Shigella sp. PIB may be the critical causative pathogen for IFC, and detection of fecal PIB plus DPA may be a reliable method for IFC diagnosis and classification.

Modified Duhamel's Two-Staged Procedure for Hirschsprung's Disease: Further Modifications for Improved Outcomes

Aims and Objectives

We studied the short- and long-term outcomes and quality of life (QOL) in patients undergoing a two-staged modified Duhamel's procedure for Hirschsprung's disease.

Materials and Methods

Patients who had undergone this modified procedure, with initial Hartmann's procedure based on contrast enema, followed by bowel preparation and low colo-anal anastomosis below the dentate line were included. The patient who underwent this procedure over 10 years with a minimum 2-year follow-up were analysed based on an interview-based questionnaire.

Results

Of the 152 patients, 69 responded. Mean age at the time of interview was 7.72 ± 3.04 years with mean follow-up of 4.9 years (2-11 years). Perineal excoriation and soiling was present in 60.9% and 36.2% of patients initially which reduced to 0 and 4.3% by the end of 2 years. In the first 6 months, postoperative period, 15.9% of patients had constipation and 78.2% had altered stool consistency. Good fecal continence score was present in 97.1% of patients in the long term. About 95.4% had good QOL scores. There was no mortality in this series.

Conclusions

Although short-term outcomes showed altered bowel function, soiling, and perineal excoriation, this improved significantly in the long term, with good QOL scores in the majority.

Comparison of laparoscopic selective colectomy based on barium-strip examination and subtotal colectomy for adult slow-transit constipation

BACKGROUND

Surgical management of adult slow-transit constipation (ASTC) can be effective for patients with intractable symptoms. This study aimed to evaluate whether barium-strip examination and selective colectomy improved post-operative outcomes in ASTC patients in comparison with subtotal colectomy.

METHODS

A retrospective cohort study of 53 cases with refractory ASTC was conducted between June 2008 and June 2014. Patients were evaluated by the barium-strip technique, colonoscopy, defecography and anorectal manometry. Patients in the standard group underwent laparoscopic subtotal colectomy and patients in the laparoscopic selective colectomy (LSC) group underwent LSC at the precise location identified by barium strip. Spontaneous bowel movements, the Wexner Constipation Scale and the Gastrointestinal Quality of Life Index (GIQLI) were assessed post-operatively at 3, 6, 12 and 24 months.

RESULTS

A total of 49 patients were included in the analysis. The median follow-up was 37 months (range, 26-60 months). The mean post-operative hospital stay was 12 days and similar between groups (P = 0.071). The length of colon resection, operative time and intra-operative blood loss were reduced in the LSC group (all P < 0.05). No major complications occurred. A similar number of patients (24 in the standard group and 25 in the LSC group) exhibited hypoganglionosis or aganglionosis in the colon-wall muscle layer (P = 0.986). Although there were no significant differences in post-operative spontaneous bowel movements and the Wexner Constipation Scale between the two groups, the mean GIQLI of the LSC group was significantly higher at 3, 6 and 24 months post-operatively (all P < 0.05).

CONCLUSIONS

LSC based on barium-strip examination is an appropriate modality for treating ASTC.

Use of high-resolution colonic manometry to establish etiology and direct treatment in patients with constipation: Case series with correlation to histology

BACKGROUND AND AIM

Different clinical treatments are available to treat patients with constipation. We aimed to study the etiology and direct treatment in a case series of patients with constipation by the use of high-resolution colonic manometry (HRCM).

METHODS

High-resolution colonic manometry was used to record the colorectal peristaltic contractions of the entire colon in patients. Based on the results of HRCM, 151 patients with constipation were classified into groups and received different clinical treatment such as a total or subtotal colectomy, local excision, or conservative treatment. Paraffin-embedded samples obtained after resection were studied using hematoxylin and eosin, as well as immunohistochemical staining.

RESULTS

All patients underwent HRCM over 24 h. Based on the amplitude, intensity, and trends in peristaltic contractions recorded by HRCM, we observed 117 patients with slow-transit constipation and 34 with functional outlet obstruction constipation. After an overall evaluation of the results of HRCM and anorectal function, 26, 23, 27, and 75 patients were treated with total colectomy, subtotal colectomy, local excision, and conservative treatment, respectively. Furthermore, histological examination of surgical samples showed vacuolar degeneration of nerve plexuses as well as of the muscularis propria, which also showed fibrosis in its outer layers in patients with constipation.

CONCLUSION

Different types of constipation showed different colonic motility patterns and morphological changes in the colonic wall. HRCM plays an important role in the diagnosis and classification of patients with constipation. Furthermore, HRCM can accurately identify the diseased colonic segments and help to choose the appropriate treatment.

Fluoroscopy-guided trans-anal decompression tube placement in the treatment of acute colonic pseudo-obstruction: a single center experience

PURPOSE

Acute colonic pseudo-obstruction (ACPO or Ogilvie's syndrome) is a rare but often fatal disease; timely colonic decompression may be essential for successful treatment. This study describes a technique of placing a trans-anal tube via fluoroscopy-guiding and investigates the effect of colon decompression on ACPO.

METHODS

Patients undergoing colonic decompression via fluoroscopy-guided trans-anal tube placement from April 2015 to May 2017 were included. The technical and clinical successes of this procedure were evaluated. Clinical features and long-term outcomes are described.

RESULTS

Decompression was successful in 72.73% (16/22) of the patients; the procedure was considered a clinical success in 50% (11/22) of the patients. 31.82% (7/22) of the patients underwent elective surgery, and only 18.19% (4/22) of the patients need emergency surgery.

CONCLUSIONS

Fluoroscopy-guided trans-anal decompression tube placement was an easy and efficient method for treating ACPO. Additionally, ACPO once required emergency surgery, but now may only require elective surgery in certain instances.

Searching for a definition for pharmacologically refractory constipation: A systematic review

BACKGROUND AND AIM

Surgery and other non-pharmacological treatments such as sacral nerve stimulation are used for the treatment of difficult-to-treat chronic constipation. Novel pharmacological therapeutic agents are also being introduced. To evaluate the efficacy of these treatments, it is imperative to have a consistent definition of pharmacologically refractory constipation. A systematic review of studies on refractory, difficult-to-treat or surgically treated constipation was carried out to determine the criteria that various authors used to define this group of patients.

METHODS

A systematic review was performed for literature published from June 2005 to June 2015 using PubMed, Cochrane, and Scopus databases, as well as manual searches. Studies on patients with refractory or intractable constipation were extracted. Criteria used for defining refractory constipation, as well as pharmacological agents tried including dosage, frequency, and duration, were reviewed.

RESULTS

Sixty-one studies were included in this review. Forty-eight involved surgical treatment of constipation, while 13 examined non-surgical therapies for refractory constipation. There is no generally accepted definition of refractory constipation. Authors consider constipation to be refractory when response to management is suboptimal, but there is no consensus on the choice of drug, order of usage, and dosage or treatment duration. Prior medical therapy was not mentioned at all in five studies.

CONCLUSIONS

There is need for a detailed definition of pharmacologically refractory constipation before submitting patients to invasive treatments and to evaluate new pharmacological agents.

Isobaric tags for relative and absolute quantification-based proteomic analysis that reveals the roles of progesterone receptor, inflammation, and fibrosis for slow-transit constipation

BACKGROUND AND AIM

Progesterone receptor, inflammation, neurotransmitter expression, and fibrosis are involved in slow-transit constipation. The aim of the present study was to examine whether patients with slow-transit constipation have an overexpression of progesterone receptor and serotonin, which may impair the fibrosis of muscularis propria in colorectal wall.

METHODS

High-resolution colon manometry was used to record the colorectal peristaltic contractions of the proximal ascending and sigmoid colon in patients. Protein samples prepared from frozen sigmoid colon tissue and the proximal margin of the ascending colon of four female patients were compared using isobaric tags for relative and absolute quantification labeling technique coupled to 2D liquid chromatography-tandem mass spectrometry analysis. Immunohistochemical staining of progesterone receptor, serotonin, and fibronectin was performed in paraffin-embedded sigmoid colon tissues and the proximal margin of the ascending colon or ileum from 43 patients with slow-transit constipation.

RESULTS

Among these differentially regulated proteins based on isobaric tags for relative and absolute quantification and liquid chromatography-tandem mass spectrometry analysis, 56 proteins involved in the response to progesterone, inflammation, matrix remodeling, fibrosis, and muscle metabolism. Immunohistochemical staining confirmed that there was significantly higher expression of progesterone receptor (t = 19.19, P = 0.000) and serotonin (t = 13.52, P = 0.004) in sigmoid colon than in the proximal margin of the ascending colon and ileum. Progesterone receptor and fibronectin expression in the outer layer of muscularis propria were higher than in the middle layer.

CONCLUSIONS

These results demonstrate that progesterone receptor, along with inflammation and fibrosis, may take part in slow-transit constipation development.

Surgery for constipation: systematic review and practice recommendations: Results I: Colonic resection

AIM

To assess the outcomes of colectomy in adults with chronic constipation (CC).

METHOD

Standardised methods and reporting of benefits and harms were used for all CapaCiTY reviews that closely adhered to PRISMA 2016 guidance. Main conclusions were presented as summary evidence statements (SES) with a summative Oxford Centre for Evidence-Based Medicine (2009) level.

RESULTS

Forty articles were identified, providing data on outcomes in 2045 patients. Evidence was derived almost exclusively from observational studies, the majority of which concerned colectomy and ileorectal anastomosis (CIRA) rather than other procedural variations. Average length of stay (LOS) ranged between 7-15 days. Although inconsistent, laparoscopic surgery may be associated with longer mean operating times (210 vs 167 min) and modest decreases in LOS (10-8 days). Complications occurred in approximately 24% of patients. Six (0.4%) procedure-related deaths were observed. Recurrent episodes of small bowel obstruction occurred in about 15% (95%CI: 10-21%) of patients in the long-term, with significant burden of re-hospitalisation and frequent recourse to surgery. Most patients reported a satisfactory or good outcome after colectomy but negative long-term functional outcomes persist in a minority of patients. The influence of resection extent, anastomotic configuration and method of access on complication rates remains uncertain. Available evidence weakly supports selection of patients with an isolated slow-transit phenotype.

CONCLUSION

Colectomy for CC may benefit some patients but at the cost of substantial short- and long-term morbidity. Current evidence is insufficient to guide patient or procedural selection.

Functional Disorders: Slow-Transit Constipation

Constipation is a very common complaint, with slow-transit constipation (STC) accounting for a significant proportion of cases. Old age, female gender, psychiatric illness, and history of sexual abuse are all associated with STC. The exact cause of STC remains elusive; however, multiple immune and cellular changes have been demonstrated. Diagnosis requires evidence of slowed colonic transit which may be achieved via numerous modalities. While a variety of medical therapies exist, these are often met with limited success and a minority of patients ultimately require operative intervention. When evaluating a patient with STC, it is important to determine the presence of concomitant obstructed defecation or other forms of enteric dysmotility, as this may affect treatment decisions. Although a variety of surgical procedures have been reported, subtotal colectomy with ileorectal anastomosis is the most commonly performed and well-studied procedure, with the best track record of success.

Treatment of Slow Transit Constipation With Fecal Microbiota Transplantation: A Pilot Study

BACKGROUND

Fecal microbiota transplantation (FMT) has been proposed as a therapeutic approach for functional gastrointestinal disease. We launched a clinical study to examine the safety and efficacy of FMT for slow transit constipation (STC).

MATERIALS AND METHODS

Twenty-four patients with STC, aged from 20 to 74 were enrolled in this prospective open-label study. Patients received FMT on 3 consecutive days through nasojejunal tubes and followed up for 12 weeks after treatment. Rate of clinical improvement and remission, Wexner constipation scale, Bowel movement per week, and gastrointestinal quality-of-life index were evaluated.

RESULTS

The rate of clinical improvement and remission based on clinical activity at week 12 was 50% (12/24) and 37.5% (9/24), respectively. The patient's stool frequency increased from a mean of 1.8 (SD 1.3) per week pre-FMT to 4.1 (SD 2.6) at week 12 post-FMT without laxative usage (P<0.01). The stool consistency showed a tendency to improve after FMT administration. Comparison of pre-FMT and post-FMT Wexner constipation scores demonstrated a significant reduction between baseline (14.1±3.3) and the first week (9.8±4.9), which was maintained up to the following 12 weeks (7.5±3.2; P<0.01). Compared with baseline, significant overall improvements were also seen in gastrointestinal quality-of-life index score at week 1, week 2, week 4, week 8, and week 12 of follow-up (P<0.01). The improvements were accompanied by the decline of colonic transit time. No severe adverse events during the whole FMT procedure follow-up except for venting (6/24), abdominal pain (3/24), bloating (2/24), and diarrhea (7/24).

CONCLUSION

This is a pilot study demonstrating that FMT was safe and may have the potential to improve symptoms in patients with STC.

Efficacy of Synbiotics in Patients with Slow Transit Constipation: A Prospective Randomized Trial

Synbiotic intake may efficiently restore the balance of gut microbiota and improve gastrointestinal functions. The aim of the study was to evaluate the efficacy of a synbiotic in patients with slow transit constipation. A total of 100 patients with slow transit constipation were randomized to receive either a synbiotic or placebo twice daily for 12 weeks. The primary efficacy endpoints were the clinical remission and improvement rates at weeks 4 and 12. Stool frequency and consistency, colonic transit time (CTT), evacuation and abdominal symptoms, patient assessment of constipation symptoms, gastrointestinal quality-of-life index scores, satisfaction scores, and adverse events were also monitored. The clinical remission rates reached 37.5% at week 4 and 45.8% at week 12 in the treatment group, compared to 13.3% at week 4 and 16.7% at week 12 in the placebo group (p < 0.01 for both comparisons). Over 12 weeks, 64.6% of the patients who received the synbiotic experienced clinical improvement, compared to 29.2% of the patients in the placebo group (p < 0.01). During the intervention period, patients who were treated with the synbiotic exhibited increased stool frequency, improved stool consistency, decreased CTT, and improved constipation-related symptoms. This randomized, placebo-controlled trial suggested that dietary supplementation with a synbiotic improved evacuation-parameters-associated symptoms and colonic motility in patients with slow transit constipation (STC).

Function and clinical implications of short-chain fatty acids in patients with mixed refractory constipation

AIM

The present study was designed to investigate the function and clinical implications of stool short-chain fatty acids (SCFAs) in patients with mixed refractory constipation.

METHOD

Ascending colon specimens obtained from 30 patients with ascending colon cancer were regarded as the control group. Ascending colon specimens obtained from patients with mixed refractory constipation were regarded as the experimental group and were divided into three subgroups, according to Wexner scores [A constipation scoring system to simplify evaluation and management of constipated patients. Dis Colon Rectum 1996; 39: 681-5] of 16-20, 21-25 and 26-30, with 30 patients in each group. The stool SCFAs were extracted and quantitatively analysed using gas chromatography-mass spectrometry (GC-MS). The expression of G protein-coupled receptor 43 (GPR43) and of choline acetyltransferase (ChAT) were detected by immunofluorescence, reverse transcription-polymerase chain reaction (RT-PCR) and western blotting of colon samples.

RESULTS

The levels of acetate, propionate and butyrate were significantly lower in the experimental group than in the control group (P < 0.05). Compared with the control group, the densitometric quantification and mean density of GPR43 and ChAT proteins, and expression of GPR43 and CHAT genes, were significantly decreased in the patients with mixed refractory constipation (P < 0.05).

CONCLUSION

In the patients with mixed refractory constipation, the levels of stool SCFAs, including acetate, propionate and butyrate, as well as the levels of GPR43 and ChAT expressed in the colon, which were all negatively correlated with the Wexner score, were decreased and may be associated with the pathogenesis of mixed refractory constipation.

Laparoscopic-assisted subtotal colectomy combined with modified Duhamel procedure for mixed constipation

Background and Objectives:

To evaluate the effects of subtotal colectomy combined with the modified Duhamel procedure on mixed constipation.

Methods:

A total of 16 female patients with mixed constipation were enrolled and underwent subtotal colectomy combined with the modified Duhamel procedure under laparoscopy from April 2010 to April 2012. Before surgery, physical examinations such as the gastrointestinal transit test, barium enema, and defecography were performed for all the patients. After surgical treatment, 2-year follow-up was performed using questionnaires to assess the effect of treatment.

Results:

All 16 cases were treated successfully, with a mean operation time of 230 minutes (range, 180–290 minutes). No intraoperative or postoperative complications were found, and no deaths occurred. Constipation and relevant symptoms were relieved, and all patients were satisfied with their quality of life. The gastrointestinal quality-of-life score was significantly increased 6 months postoperatively (mean, 102) compared with preoperatively (mean, 75).

Conclusion:

Subtotal colectomy combined with the modified Duhamel procedure under laparoscopy is effective and safe for the treatment of mixed constipation.

Advancing treatment options for chronic idiopathic constipation

INTRODUCTION

Chronic constipation is a global problem affecting all ages and associated with considerable morbidity and significant financial burden for society. Though formerly defined on the basis of a single symptom, infrequent defecation; constipation is now viewed as a syndrome encompassing several complaints such as difficulty with defecation, a sense of incomplete evacuation, hard stools, abdominal discomfort and bloating.

AREAS COVERED

The expanded concept of constipation has inevitably led to a significant change in outcomes in clinical trials, as well as in patient expectations from new therapeutic interventions. The past decades have also witnessed a proliferation in therapeutic targets for new agents. Foremost among these have been novel prokinetics, a new category, prosecretory agents and innovative approaches such as inhibitors of bile salt transport. In contrast, relatively few effective therapies exist for the management of those anorectal and pelvic floor problems that result in difficult defecation.

EXPERT OPINION

Though constipation is a common and often troublesome disorder, many of those affected can resolve their symptoms with relatively simple measures. For those with more resistant symptoms a number of novel, effective and safe options now exist. Those with defecatory difficulty (anismus, pelvic floor dysfunction) continue to represent a significant management challenge.

Chronic severe constipation: current pathophysiological aspects, new diagnostic approaches, and therapeutic options

Chronic constipation is a considerable problem because it significantly affects the quality of a patient's life. Constipation can be diagnosed at every age and is more frequent in women and among the elderly. In epidemiological studies, its incidence is estimated at 2-27% in the general population. Chronic constipation may be primary or secondary. However, primary constipation (functional or idiopathic) can be classified into normal transit constipation, slow transit constipation, and pelvic outlet obstruction. In this review we make an attempt to present the current pathophysiological aspects and new therapeutic options for chronic idiopathic constipation, particularly highlighting the value of patient assessment for accurate diagnosis of the cause of the problem, thus helping in the choice of appropriate treatment.

Changes in Fecal and Colonic Mucosal Microbiota of Patients with Refractory Constipation after a Subtotal Colectomy

The purpose of this study was to investigate the changes in gut microbiota of patients with refractory constipation 6 months after a subtotal colectomy. Feces and mucosal samples of five healthy volunteers and 17 patients with refractory constipation before and six months after subtotal colectomy were collected. Denaturing gradient gel electrophoresis (DGGE) and polymerase chain reaction techniques were used for quantitative analysis of main bacterial groups and archeal methanogens. No significant differences were found in the DGGE profiles among the three groups. After subtotal colectomy, a significantly decreased similarity coefficient was observed in the fecal. The Shannon diversity indices had no significant differences among the three groups. The numbers of predominant bacteria (Bacteriodetes, Clostridium coccoides group, and Clostridium leptum group) did not significantly change in patients before and after surgery compared with healthy control subjects, and the number of total bacteria, Firmicutes, Bacteriodetes, and Clostridium leptum group bacteria in the feces decreased after surgery. However, the numbers of these bacteria remained the same in mucosa from postoperative patients. The numbers of Bifidobacteria and Lactobacilli in feces and the number of Bifidobacteria in mucosa were significantly lower in preoperative compared with healthy control subjects and increased after the surgery. The number of methanogens in the mucosa was decreased in preoperative patients but returned to normal levels postoperatively. In conclusion, although there was no difference in the structure of the predominant bacteria between refractory constipated patients and healthy control subjects, the number of probiotics ( Bifidobacteria and Lactobacilli) was significantly lower in refractory constipated patients. However, subtotal colectomy can significantly normalize the number of intestinal flora.

Clinical and pelvic morphologic correlation after subtotal colectomy with colorectal anastomosis for combined slow-transit constipation and obstructive defecation

BACKGROUND

The treatment of slow-transit constipation combined with outlet obstruction is controversial. Subtotal colectomy with colorectal anastomosis is regarded as a safe and effective surgical option for refractory constipation.

PURPOSE

The clinical and morphologic outcomes of patients who underwent subtotal colectomy with colorectal anastomosis for refractory mixed constipation were prospectively evaluated.

DESIGN

This study is a nonrandomized, prospective review of gathered data.

SETTING

This investigation was conducted at a tertiary-care GI surgical center in China.

PATIENTS

The study prospectively included 42 consecutive patients with refractory constipation who were diagnosed with obstructed defecation syndrome combined with slow colon transit.

MAIN OUTCOME MEASURES

The primary outcomes measured were the Longo obstructive defecation syndrome score and the Wexner constipation scale. The pelvic morphologic changes were determined with defecography before surgery and at 6 and 24 months after surgery.

RESULTS

A significant reduction in the Wexner constipation score was observed between baseline (median 24) and 6 months (median 10), which was maintained until 24 months (median 8, compared with baseline, p < 0.01). Improvement in the constipation score was matched by an overall improvement in the Longo obstructive defecation syndrome score at the 6- and 24-month follow-up times (compared with baseline, p < 0.01). In 17 of 21 patients, preexisting intussusception was no longer visible during defecography. Rectoceles were significantly reduced in depth, from 36 mm to 8 mm (p < 0.01), whereas the number of detectable rectoceles was also significantly decreased, from 29 to 7 (p < 0.01). Incomplete evacuation disappeared in 28 of 38 patients. No stenosis was observed at the colorectal posterior side-to-side anastomosis. Most complications were managed conservatively without significant events.

LIMITATIONS

This study was performed in selected patients with constipation and did not include a comparison group.

CONCLUSIONS

Subtotal colectomy with colorectal anastomosis can correct pelvic anatomical disorders in patients with mixed refractory constipation. The clinical improvement of obstructed defecation syndrome after subtotal colectomy with colorectal anastomosis is highly correlated with the morphologic correction of the rectal redundancy.

A modified total colonic exclusion for elderly patients with severe slow transit constipation

BACKGROUND

The aim of this study was to evaluate outcomes of total colonic exclusion with antiperistaltic ileorectal anastomosis (TCE-AIA) for elderly patients with slow transit constipation (STC).

METHODS

Elderly patients (defined as age >65) who underwent TCE-AIA for severe idiopathic STC between 2009 and 2012 at our institution were identified. Postoperative outcomes and routine follow-up were assessed using the Wexner constipation score (WCS), gastrointestinal quality of life index (GIQLI) and four-point postoperative satisfaction scales.

RESULTS

A total of 13 elderly patients were met the inclusion criteria. Five patients (38.5%) were male, and eight patients (61.5%) were female. The mean age of this population was 74 years (range 63-82 years). The mean operative time was 55 min (range 28-32), and blood loss was minimal. The mean postoperative hospital stay was 6.7 days (range 5-12 days). The mean time until the first postoperative bowel movement was 4 days (range 2-8 days). There was no procedure-related mortality and no major in-hospital complications. The median duration of follow-up was 12.4 months (range 6-29 months). None of the 13 patients had fecal incontinence or recurrence of constipation at the follow-up end point. However, eight patients underwent colonoscopy during follow-up, and four patients presented with diversion colitis. The patients' preoperative WCS was 22.8 ± 3.3, and it had significantly improved to 5.4 ± 2.1 on 6 months after operation (p < 0.05). The preoperative GIQLI of 93.6 ± 20.5 had significantly increased to 120.8 ± 13.0 on 6 months after surgery (p < 0.05). Patient satisfaction at 6 months was very high in 11 patients and high in two patients.

CONCLUSIONS

TCE-AIA is a relatively simple procedure. It might be an effective surgical intervention for the selected elderly patients with STC.

Long-term outcomes and quality of life after subtotal colectomy combined with modified Duhamel procedure for adult Hirschsprung's disease

BACKGROUND

Subtotal colectomy combined with modified Duhamel procedure (Jinling procedure) was used in patients with adult Hirschsprung's disease (AHD) at Jinling Hospital in the last decade. The aim of this study is to evaluate the safety, effectiveness and quality of life of Jinling procedure for AHD.

MATERIALS AND METHODS

All the data are from the database of the Jinling Hospital Constipation Registry System. Primary outcomes, including safety (morbidity and adverse events), effectiveness (satisfaction rate, Wexner constipation scale (WCS) and bowel function score (BFS)) and gastrointestinal quality of life index (GIQLI), were all evaluated.

RESULTS

Fifty-nine patients were available for this study and the mean postoperative period was 44 months. Seventeen major complications were found in 11 patients and most of the complications could be managed conservatively. A significant improvement in WCS, BFS and GIQLI at 6 months postoperatively was obtained.

CONCLUSION

Jinling procedure is safe and effective for AHD.
