Etiological analysis and surgical method selection of adult megacolon

Adult megacolon is a rare disease with heterogeneneous etiology. The treatment schemes of megacolon caused by different causes are also different, but surgery is the final and the most effective method. Due to the lack of early understanding of the disease, many patients have not been clearly diagnosed as adult megacolon and have not been properly treated. This article classifies adult megacolon according to the etiology and summarizes its surgical options. For adult Hirschsprung's disease, modified Duhamel, the Jinling procedure, low anterior resection, or pull-through low anterior resection can be used. For patients with idiopathic megacolon, one-stage subtotal colorectal resection can be selected with adequate preoperative preparations. Some patients admitted to the hospital with emergency intestinal obstruction can be treated with conservative treatment or decompression under colonoscopy followed by selective surgery. For patients with aganglionosis, the procedure is subtotal colorectal resection, the same as that of idiopathic megacolon. The procedure is to remove both the dilated proximal intestine and the stenotic distal intestine, then an ileorectal anastomosis or ascending colon rectal anastomosis is performed. For toxic megacolon, colostomy can be done for mild cases, and for severe infections, subtotal colorectal resection is required. Latrogenic megacolon is mostly caused by segmental stenosis or lack of peristalsis, resulting in chronic dilatation of the proximal end and the formation of megacolon. It is necessary to choose a reasonable surgical procedure according to the specific conditions of the patient. The first choice for the treatment of acute colonic pseudo-obstruction syndrome is decompression under colonoscopy. For those with the secondary changes in the intestine, ostomy is still the most effective surgical procedure, but should be performed with caution.

Efficacy and safety of the Jinling procedure in the treatment of adult Hirschsprung disease

To investigate the safety, efficacy and long-term outcomes of Jinling procedure in the treatment of adult Hirschsprung disease. Clinical and follow-up data of 125 patients with adult Hirschsprung disease undergoing Jinling procedure at the Department of General Surgery between January 2000 and January 2013 were summarized. All the patients were diagnosed by CT, barium enema, anorectal pressure detection and pathology examination. Abdominal symptoms, gastrointestinal quality of life index(GIQLI, the lower score, the worse quality of life), Wexner constipation score (higher score indicated worse symptom), defecography (evaluation included rectocele, mucosal prolapse, intramucosal intussusception, perineal prolapse) and other operative complications were compared before and after operation. Among 125 patients, 69 were male and 56 were female with median age of (41.2±15.5) (18 to 75) years. The follow-up rates were 94.4%(118/125), 92.0%(115/125), 89.6%(112/125) and 88.0%(110/125) at postoperative months 1, 3, 6, and 12. Incidences of abdominal distension and abdominal pain were 100% and 82.4%(103/125) before operation, and were 7.3%(8/110) and 20.9%(23/110) at 12 months after surgery. Wexner score was significantly lower at postoperative months 1(8.7±2.9), 3 (7.2±2.8), 6(6.7±2.2) and 12(6.3±1.7) than that before operation (21.4±7.2) (P<0.01). GIQLI score was 51.6±11.9 before operation, though it decreased at 1 month (47.3±5.5)(P<0.05) after surgery, but increased significantly at postoperative months 3, 6, 12(68.9±8.0, 96.5±8.2, 103.2±8.6)(P<0.01). Abnormal rate of defecography was 70.4%(81/115), 48.2%(54/112) and 27.3%(30/110) at postoperative months 3, 6, 12, which was significantly lower than 91.2%(114/125) before operation (P<0.01). Morbidity of postoperative complication was 29.6%(37/125), including 5 cases of surgical site infection (4.0%), 2 of anastomotic bleeding (1.6%), 8 of anastomotic leakage (6.4%, one died of severe abdominal infection), 4 of urinary retention (3.2%), 3 of recurrent constipation (2.4%, without megacolon relapse), 11 of bowel obstruction (8.8%), 2 of anastomotic stricture(1.6%) and 2 of refractory staphylococcus aureus enteritis (1.6%, diagnosed by stool smear and culture, and both died finally). Jinling procedure is a safe and effective surgical procedure for adult Hirschsprung's disease.

Therapeutic effect and long-term follow-up of the Jinling procedure for refractory constipation: a series of 1 100 cases

To investigate the safety, effectiveness and long-term results of Jinling procedure. A total of 1 100 patients with refractory constipation were admitted to the Institute of General Surgery between February 2000 and December 2013 and received Jinling procedure. There were 217 male and 883 female patients with an average age of (45±15) years and an average duration of (275±159) months. The Jinling procedure modifies the classic procedure of subtotal colectomy with colorectal anastomosis by adding a new side-to-side cecorectal anastomosis. The general clinical data, postoperative complications, gastrointestinal quality of life index (GIQLI), Wexner constipation score, satisfaction rate, body composition, nutritional status, homeostasis, anal manometry and defecography during follow-up were collected. Statistical analysis was performed by t-test analysis, χ(2) test or Fisher's exact probability. The postoperative follow-up rate were 96.73%, 94.36%, 93.00% and 92.55% at 1, 3, 6, and 12 months. The satisfaction rate were 62.50%, 72.45%, 93.16% and 94.70% respectively during 1, 3, 6 and 12 months follow-up. The postoperative 1 month, GIQLI was lower than that of preoperative (P=0.038), but significantly better at postoperative 3 month than the preoperative (P=0.022), and gradually improve after then. Wexner score was significantly lower at postoperative 1 month than the preoperative (P=0.018), and with the gradually reduce. Compared to the preoperative baseline, all body composition and serum protein parameters decreased significantly at the one-month follow-up and then increased gradually over the remaining follow-up period. Weight and prealbumin were significantly higher than the preoperative at postoperative 12 month. Jinling procedure had no effect on electrolytes. All patients were detected in defecography before surgery, but these abnormal indicators were improved after surgery. Anal function, coordinated movement anorectal function, anorectal reflex and rectal sensation were injured at early postoperative, but as time goes on, these indicators gradually returned to preoperative levels, some indicators better than the preoperative level. Postoperative surgical site infection, anastomotic bleeding , anastomotic leakage, urinary retention, sexual dysfunction, recurrent constipation, bowel obstruction, anastomotic stricture and mortality rates were 4.36%, 5.45%, 6.00%, 6.91%, 0.64%, 0.45%, 8.82%, 4.00% and 0.27% respectively. Jinling procedure is a safe and effective surgical procedure for refractory constipation. It can improve defecation function and quality of life significantly, and has a high follow-up satisfaction rate.

Outcomes after surgery for refractory constipation patients complicated with megacolon

To explore the efficacy of different procedures for refractory constipation complicated with megacolon. Clinical data of 112 patients of refractory constipation complicated with megacolon undergoing surgery in our institute from June 2007 to January 2013 were retrospectively analyzed. Of these 112 patients, the duration of constipation ranged from 4 to 22 years. Seventy-four patients had previous abdominal operations. Surgical procedures: (1)Jinling procedure (subtotal colectomy plus ascending colorectal posterior wall side-to-side anastomosis, n=81), including 24 laparoscopy-assisted procedures, 18 terminal ileostomies. (2)total colectomy plus ileorectal side-to-side anastomosis(n=18). (3)total colectomy plus end ileostomy, and ileorectal posterior wall side-to-side anastomosis 6 months later(n=13). The end ileostomy was reversed 6 months after operation. The successful rate was 100%, and no surgery-related deaths were found. Postoperative complications included early diarrhea (90 cases, 80.4%), anal pain and incomplete evacuation (22 cases, 19.6%), urinary retention within 24-48 h after catheter removal (16 cases, 14.2%), anastomosis bleeding (9 cases, 8.0%), anastomosis leakage (6 cases, 5.4%), and intestinal obstruction (15 cases, 13.4%). Six patients with intestinal obstruction underwent adhesiolysis, and others were managed by conservative therapy. At the postoperative follow-up at 6 months, the Wexner constipation score was significantly reduced (5.8-8.3 vs. 21.4-28.7, P<0.01), and malnutrition improved as well. Surgical intervention results in good efficacy for refractory constipation complicated with megacolon.

Novel surgery for refractory mixed constipation: Jinling procedure - technical notes and early outcome.

IntroductionThe treatment of slow-transit constipation combined with outlet obstruction is controversial. This study introduced a new surgical strategy, subtotal colectomy combined with a modified Duhamel procedure (Jinling procedure), of which the safety and satisfactory rate were examined.Material and methodsNinety patients with refractory slow-transit constipation associated with outlet obstruction were consecutively included between Jan 2010 and Dec 2010. All underwent the laparoscopic-assisted Jinling procedure, which added a new side-to-side anastomosis to the colorectal posterior anastomosis after subtotal colectomy. The pre- and post-operative data were collected.ResultsThere was no surgery-related death. A total of 39 complications and adverse events were reported in 22 patients (morbidity rate of 24.4%). Most complications were managed conservatively without significant events. The satisfactory rate was 93.1% at 6-month follow-up.ConclusionsThe Jinling procedure is safe for refractory slow-transit constipation associated with outlet obstruction, with minimal major complications and a high satisfaction rate. However, this procedure requires rigorous preoperative examination, exquisite surgical and laparoscopic techniques and excellent perioperative management. The pelvic floor, especially the presacral space, is damaged, and therefore it may be unsalvageable if severe complications, such as anastomosis leakage or ischemia, occur.

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

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. 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. 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. Jinling procedure is safe and effective for AHD.

Long-term Follow-up of the Jinling Procedure for Combined Slow-Transit Constipation and Obstructive Defecation

Surgery is indicated for chronic constipation refractory to conservative therapy. The treatment of combined slow-transit constipation and obstructive defecation is controversial. The aim of the study is to describe the Jinling procedure and examine safety, effectiveness, and quality of life over 4 years of follow-up. The study is a retrospective review of prospectively gathered data in a patient registry database. This investigation was conducted at a tertiary-care gastroenterology surgical center in China. The study included 117 consecutive patients with slow-transit constipation combined with obstructive defecation treated between January 2005 and December 2007. The Jinling procedure modifies the classic procedure of subtotal colectomy with colorectal anastomosis by adding a new side-to-side cecorectal anastomosis to solve the coexistence of obstructive defecation and slow-transit constipation in one operation. We measured morbidity and mortality rates, Wexner constipation scores, and Gastrointestinal Quality of Life Index at baseline and after 1, 6, 12, 24, 36 and 48 months of follow-up. A total of 117 patients underwent the Jinling procedure, which was laparoscopically assisted in 56 patients (47.9%) and an open procedure in 61 patients (52.1%). Of the total, 72 patients (61.5%) had undergone previous surgical intervention without improvement. A total of 28 complications and adverse events were reported in 117 procedures, giving an overall morbidity rate of 23.9%; 23 patients (19.7%) had 1 or more events. Most complications were managed conservatively. A significant reduction in Wexner constipation score was observed from baseline (mean, 21.9) to 1 month (mean, 9.8), and the reduction was maintained at 48 months (mean 5.1; p < 0.001). Compared with baseline, significant overall improvements were also seen in gastrointestinal quality of life at 12, 24, and 48 months of follow-up (p < 0.01). This study did not include a comparison group. Our clinical practice demonstrates that Jinling procedure is safe and effective for refractory slow-transit constipation associated with obstructive defecation, with minimal major complications, significant improvement of quality of life, and a high satisfaction rate after 4-year follow up.

Novel surgery for refractory mixed constipation: analysis of the technical notes and outcome to Jinling procedure

To discuss a new surgical strategy: Jinling procedure (subtotal colectomy combined with modified Duhamel procedure), of which the indications, technical notes and outcomes were analyzed. The 590 patients with refractory slow-transit constipation associated with outlet obstruction was strictly included between February 2000 and December 2011. The patients included 103 males and 487 females. Their age were 14-75 years (average 42 ± 13). The 412 patients received laparoscopic-assistant Jinling procedure, and 178 patients with open Jinling procedure. The pre- and post-operation data were collected. The follow up rate were 100%, 98.1%, 95.8% and 92.7% at 3, 6, 12 and 24 months. There was no surgery-related death. Mean hospital day was (12 ± 9) days. Most complications were managed conservatively without significant events. The common complications after surgery were adhesive intestinal obstruction (9.2%), anastomosis bleeding (8.1%) and anastomosis leakage (2.9%). The gastrointestinal quality of life index score was 72 ± 9 preoperatively and increased to 68 ± 11, 99 ± 6, 105 ± 9, 106 ± 9 at 3, 6, 12 and 24 month follow-up, respectively (t = 62.1, -25.1, -126.5, -143.2, P < 0.01). The Wexner constipation scale was 21.9 ± 4.5 preoperatively and decreased to 9.6 ± 2.4, 5.9 ± 2.1, 4.6 ± 1.9, 4.5 ± 1.8 at 3, 6, 12 and 24 month follow-up, respectively (t = 48.6, 61.8, 58.2, 45.9, P < 0.01). The satisfactory rate was 77.5%, 92.1%, 93.0% and 94.1% at 3, 6, 12, and 24 month follow-up. Jinling procedure provides a good surgical option for refractory slow-transit constipation associated with outlet obstruction.

Surgical innovation for refractory constipation (Jinling procedure): a long-term follow-up of its safety and efficacy

To propose a novel surgical procedure for refractory constipation, namely Jinling procedure, and to explore its safety and efficacy through long-term follow-up. A total of 614 patients with refractory constipation were admitted to the Department of General Surgery between February 2000 and June 2011. Five hundred and fifty-four patients received Jinling procedure and were included in this study. The general clinical data, complications after Jinling procedure, gastrointestinal quality of life index (GIQLI), Wexner constipation scale and satisfaction rate during follow-up were collected. No operation-associated death occurred. Increased bowel movement frequency was observed during the perioperative period. Temporary difficulty in urination occurred in 24.5% of the patients. Other complications included small bowel obstruction (9.6%), anastomotic bleeding (8.1%), anastomotic leakage (3.1%), sexual dysfunction (3.1%), and wound infection (3.1%). Most postoperative complications were managed conservatively. The most recent follow-up was on August 2011, and the follow-up rate was 100%, 88.8%, 75.1%, 56.3% at 3, 6, 12, and 24 months after surgery. GIQLI temporarily increased from 78.1±9.4 preoperatively to 92.0±9.5 at 3 months follow-up, but continued to decrease during the follow-up at the 6 months (48.4±14.1), 12 months (21.0±4.3), and 24 months (20.0±3.4). Wexner constipation scale decreased from 19.9±4.3 preoperatively to 8.4±2.1 at 3 months follow-up (P<0.01). The low Wexner scale sustained until 24 months after operation. The satisfaction rate at the 3, 6,12 and 24 months follow-up was 78.1%, 91.1%, 94.2% and 94.6%, respectively. Jinling procedure provides refractory constipation patients with a novel, safe and effective surgical option.

Changes of defecography pre- and post-Jinling procedure for mixed constipation: a prospective single center study

To evaluate the anatomy and functional changes of pelvis before and after Jinling procedure (subtotal colectomy and side-to-side colorectal anastomosis) using defecography. Fifty patients with refractory mixed constipation received Jinling procedure in the Jinling Hospital between March 2009 and December 2010 and were included in this prospective study. The defecography was performed at one week before surgery and 6 months after Jinling procedure. Longo outlet obstructed score, Wexner constipation score and Wexner incontinence score were also recorded before and after the procedure. After 6 months follow-up, defecography showed that anterior rectocele, prolapse, intussusception, and descending perineum were significantly improved (P<0.01). Anterior rectoceles were significantly reduced in depth from 22.0±1.8 mm to 2.4±0.4 mm (P<0.01). Intussusception decreased from 1.9±0.4 cm to 0.4±0.5 cm (P<0.01). Compared with preoperative score, Longo score and Wexner constipation score were significantly improved from 17.6±3.8 to 5.3±2.0 and from 19.5±4.8 to 5.5±2.4, respectively (P<0.01). Jinling procedure can correct the anatomy and functional pelvic disorders in mixed constipation. Clinical improvement of obstructed defecation syndrome after Jinling procedure correlates well with morphologic correction of the rectal redundancy.

A New Surgical Innovation for Chronic Constipation (Jinling Procedure): 2 Years Follow-up

Purpose: Surgery is indicated for chronic constipation, which is refractory to conservative therapy. Of the three different types of constipation, the treatment of slow-transit constipation combined with outlet obstruction is controversial. This study proposed a surgical innovation, Jinling procedure, of which the safety, effectiveness and quality of life was examined over a 2-year follow up. Methods: Patients with refractory slow-transit constipation associated with outlet obstruction was strictly included. All received Jinling procedure, which added a new side-to-side anastomosis to colorectal posterior anastomosis after subtotal colectomy. Primary outcomes include safety (morbidity and adverse events), effectiveness (Wexner constipation score and satisfaction rate), and Gastrointestinal Quality of Life Index (GIQLI) documented at baseline and at 3, 6, 12 and 24 months. Results: Between Jan 2005 and Jun 2009, of the 304 patients, 214 (70.4%) received laparoscopic-assistant Jinling procedure; the other 90 (29.6%) received open Jinling procedure. 130 (42.8%) patients had previous surgical intervention without improvements. A total of 107 complications and adverse events were reported in 82 patients (morbidity rate of 35.3%). Most complications were managed conservatively. A significant reduction in Wexner constipation score was observed between baseline (mean 19.9) and 3 months (mean 8.3), which was maintained at 24 months (mean 4.4, p<0.001). Improvement in constipation score was matched by an overall improvement in GIQLI at 6-, 12- and 24-month follow-up.Table: No Caption available.Table 2: Safety data: morbidity and adverse eventsConclusion: Our clinical practice demonstrates that Jinling procedure is safe and effective for refractory slow-transit constipation associated with outlet obstruction, with minimal major complications, significant improvement of quality of life and high satisfaction rate after two-year follow up.Figure
