OBJECTIVETo compare the safety and efficacy of the medial approach(MA) and the lateral approach (LA) in the treatment of colorectal disease.
METHODSStudies published from January 1994 to April 2013 that compared MA to LA in laparoscopic colorectal resection were collected. Publications in English were mainly identified from Medline, Embase, Cochrane Library, and those in Chinese from Wanfang database and CNKI database. Conversion rate, operative time, blood loss, number of harvested lymph nodes, hospital stay, complication, mortality, recurrence, and hospitalization costs of MA and LA were meta-analyzed using fixed-effect and random-effect models.
RESULTSFive cohort studies (2 randomized controlled trials and 3 retrospective studies) including 881 patients were enrolled and analyzed. Of these patients, 416 and 465 underwent laparoscopic colorectal resection with MA and LA respectively. As compared to LA, MA had significantly lower conversion rate (OR=0.42, 95%CI:0.25-0.72, P=0.001), shorter operative time (WMD=-52.62, 95%CI:-63.23--42.01, P<0.01), less number of harvested lymph nodes (WMD=-1.17, 95%CI:-1.89--0.45, P=0.001), while blood loss was less and hospitalization cost lower. Significant differences in intraoperative complications and postoperative complications were not found between the two group (OR:0.57, 95%CI:0.15-2.18, P=0.41; OR:0.78, 95%CI:0.52-1.17, P=0.23).
CONCLUSIONSCompared with LA, MA has the advantages of shorter operative time and lower conversion rate with similar safety. Differences in blood loss, hospitalization cost and oncological safety between the two approaches warrant further investigation.

Hereditary colorectal cancer accounts for approximately 5% of all colorectal cancer cases, mainly including familial adenomatous polyposis and Lynch syndrome. Total proctocolectomy plus ileal pouch-anal anastomosis and total colectomy plus ileorectal anastomosis are two major procedures for familial adenomatous polyposis, however, the exact impact of these two procedures on surgical efficacy, oncologic efficacy as well as functional results still remains uncertain. Segmental colectomy and total colectomy are two major procedures for Lynch syndrome, each of them both has advantages and disadvantages, and there still lacks a consensus about the optimal strategy because of the nature of retrospective study with a relatively insufficient evidence support. As a result, we would make a review about the current surgical treatment status and future perspectives of hereditary colorectal cancer.

OBJECTIVETo discuss a new surgical strategy: Jinling procedure (subtotal colectomy combined with modified Duhamel procedure), of which the indications, technical notes and outcomes were analyzed.
METHODSThe 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.
RESULTSThere 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.
CONCLUSIONSJinling procedure provides a good surgical option for refractory slow-transit constipation associated with outlet obstruction.

OBJECTIVETo consider the relationship to survival rate and quality of life with pararectal lymphadenectomy for lower carcinoma of rectum.
METHODSThe radical operation was performed on 780 cases of progressive cancer located at peritoneal reflection or below it, Among them, 352 cases only cleared in abdominal cavity, 428 cases coupled with extra-peritoneal histopathological type.
RESULTSUrinary function injured, the group cleared in abdominal cavity was 12 cases, accounted for 3.6%; the group coupled with extra-peritoneal clearance was 225 cases, for 52.5% (P < 0.01). Sexual function damaged (only for male), the abdominal cavity group was 23 cases, for 12.6% (23/185); the coupled group was 127 cases, for 53.4% (127/238), (P < 0.01). Local relapse rate, the abdominal cavity group was 15.8% (56/352); the coupled group was 8.6% (41/428), (P < 0.05). 5-year survival rate, the abdominal cavity group was 52.2%; the coupled group was 58.5% (P < 0.05).
CONCLUSIONBy contrast, although abdominal cavity coupled with extraperitoneal lymphadenectomy acted to cut down local relapse and to elevate 5-year survival rate, the postoperative quality of life appeared to be seriously affected.

OBJECTIVETo evaluate the safety and feasibility of hand-sewn anastomosis in totally laparoscopic colectomy.
METHODSClinical data of 19 consecutive patients with benign(n=5) or malignant colonic diseases(n=14, 4 ascending colon cancers, 2 transverse colon cancers, and 8 sigmoid colon cancers) treated with totally laparoscopic colectomy with a hand-sewn anastomosis were reviewed. All the procedures were performed by the same surgeon team including totally laparoscopic resection and hand-sewn anastomosis, ileocolic anastomosis after right hemicolectomy, and hand-sewn purse-string sutures in the colon.
RESULTSHand-sewn anastomosis was performed for 11 patients and circular-stapled anastomosis with hand-sewn purse-string sutures was performed for other 8 patients. The mean hand-sewn anastomosis time was (49.5 ± 29.4) min, and the mean hand-sewn purse-string sutures time was (13.3 ± 5.5) min. No patients required conversion to laparoscopy-assisted or open surgery, and there were no postoperative complications related to anastomosis. One patient with transverse colon lipoma developed mild intra-abdominal infection after surgery and recovered after conservative treatment.
CONCLUSIONTotally laparoscopic intracorporeal hand-sewn anastomosis or hand-sewn purse-string sutures for colectomy is feasible and safe when performed by experienced laparoscopic surgeons.

OBJECTIVETo compare primary anastomosis after intraoperative colonic defecation and Hartmann procedure for obstructive left colon cancer.
METHODSClinical data of 68 patients who underwent emergent laparotomy for left colon cancer with acute bowel obstruction between January 2000 and January 2008 were analyzed retrospectively.
RESULTSPrimary resection and anastomosis with intraoperative defecation was performed in 43 patients and Hartmann's procedure in 25 cases. Patients in both groups were comparable in terms of age, gender, nutritional status, underlying diseases, tumor location and stage, etc. The morbidity and mortality in the two groups were 25.6% vs 28.0% (P=0.761) and 2.3% vs 4.0% (P=0.369), respectively, and the differences were not statistically significant. The length of hospital stay (including first resection operation and second admission for colostomy closure) was (16.6+/-7.8) d in the primary anastomosis group and (24.6+/-9.4) d in the Hartmann procedure group, and the difference was statistically significant (P=0.002). The costs of hospitalization in the two groups were CNY 50,192.8+/-39,727.4 and CNY 58,382.1+/-30,304.9 (P=0.020).
CONCLUSIONPrimary resection with intraoperative colonic defecation is safe and effective, and should be considered as an alternative to Hartmann procedure for obstructive left colon cancer in selected patients.

OBJECTIVETo investigate the safety and feasibility of laparoscopy-assisted total proctocolectomy using medial-to-lateral approach.
METHODSBetween October 2005 and January 2012, 21 consecutive patients underwent laparoscopic-assisted total proctocolectomy by medial-to-lateral approach in Department of General Surgery in Nanfang Hospital. The clinical data and follow-up results were reviewed.
RESULTSTwenty cases underwent laparoscopic resection successfully, and 1 case (4.8%) was converted to open surgery because of serious peritoneal cavity adhesion. The mean operative time was (237.1±64.2) min and intraoperative blood loss was (90.0±77.7) ml. The mean time to first flatus was (2.7±0.8) days. The mean postoperative hospital stay was (11.8±5.7) days. Three patients (14.3%) experienced postoperative complications, including anastomotic leakage (n=1), lymphatic leakage (n=1), and anastomotic stricture (n=1). The median follow-up was 22 months (4-60 months). There were two deaths including one patient died of progressive disease 5 months after surgery and the other died of multiple organ failure.
CONCLUSIONSThe advantages of laparoscopy-assisted total proctocolectomy using medial-to-lateral approach include simplified surgical procedure, clearly revealed surgical plane, and shortened operative time. This procedure is safe and feasible in the experienced department of laparoscopic colorectal surgery.

BACKGROUNDThe incidence of chronic ulcerative colitis (CUC) in China is remarkably increasing, while little information on surgical treatment has been reported. This study aimed to completely describe and analyze the clinical outcome of restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) for CUC in China.
METHODSNinety-five consecutive patients, who suffered CUC and had surgical indications, were carefully selected. All patients underwent IPAA. Data on patient characteristics, surgical indications, surgical details, postoperative complications, functional outcome, and quality of life were collected.
RESULTSThe mean patient age at the time of the operation was 32 years. Twenty-nine (31%) patients underwent an emergency operation, and 66 (69%) underwent elective procedures. Four patients with severe dysplasia underwent operations, but no carcinoma was histologically confirmed. A two-stage operation was performed in 87 (92%) patients, and a hand-sewn technique was applied in 88 (93%) patients. Sixteen patients (17.0%) experienced early complications, and there was a significant difference between the emergency surgery group and the elective group (31.0% vs. 10.6%, respectively; P < 0.01). Five (5.3%) patients developed pouchitis as a late complication. The mean stool frequency after the operation was 4.6 (2-11) during the first 24 hours and 1.5 (0-4) overnight. According to the Kirwan grading scale, 87 (91.8%) patients showed satisfactory anal continence function. The quality of life improved significantly from a preoperative mean value of 0.28-0.61 before ileostomy closure to 0.78 after ileostomy closure (P < 0.01) according to the Cleveland Global Quality of Life index.
CONCLUSIONSIPAA is an effective and safe surgical procedure for patients with CUC in China. However, some characteristics, such as the low incidence of pouchitis, require further study.

OBJECTIVETo investigate and analyse curative effects of Miles operation and anal sphincter preserving operation for rectal carcinoma in 20 years.
METHODSFrom 1984 to 2004, 618 cases of rectal carcinoma that underwent radical resection including Miles operation and anal sphincter preserving procedures were analysed retrospectively each 10 years, earlier 10 years from 1984 to 1994, and later 10 years from 1994 to 2004.
RESULTSAmong the 618 cases, 492 (79.6%) were followed up. The median of the follow-up time was 5.4 years. In the earlier 10 years, local recurrence rate of post operation was 6.9% (14/201), for Miles operation and anal sphincter preserving procedures the local recurrence rate was 6.7% and 7.1% respectively. In the later 10 years, the local recurrence rate was 5.1% (15/291), 4.8% for Miles operation, 5.2% for anal sphincter preserving procedures. With the procedure of canular anastomosis of colon and rectal mucosa, the local recurrence rate was 4.9%. Overall five-year survival rate was 64.7% (130/201) in the earlier 10 years, 66.3% (59/89) for Miles operation, 63.4% (71/112) for anal sphincter preserving procedures. In the later 10 years, the five-year survival rate was 68.0% (198/291) in all, for Miles operation 66.3% (55/83), for anal sphincter preserving procedures 68.7% (143/208). With the procedure of canular anastomosis of colon and rectal mucosa, the five-year survival rate was 71.3% (62/87).
CONCLUSIONSThe operation for rectal cancer should be chosen individually according to locus, biological character, and clinical stages. Anal sphincter preserving procedures are performed increasingly, and they provide the same five-year survival rate as Miles operation does, and the patient's quality of life can be improved obviously.

OBJECTIVETo explore the safety and curative effect of per anus intersphincteric rectal dissection and direct coloanal anastomosis (PIDCA) for patients with very low rectal cancer.
METHODSNineteen patients were prospectively studied from June 2002 to October 2004. There were 11 males and 8 females, with a median age of 56 (range, 41 - 74) years. Nineteen patients had T(1) to T(4) tumors (T(1), n = 4; T(2), n = 10; T(3), n = 4; T(4), n = 1) located between 3.5 and 5.0 cm above the anal verge.The rectum, including the entire width of the internal analsphincter, was transected circumferentially via the anal route to secure the surgical margin of safety under direct vision and was mobilized proximally as far as possible through the intersphincteric plane. Per anus coloanal anastomosis was performed following transabdominal resection of the rectum.
RESULTSThere was no operative mortality. Of nineteen patients, two (10.5%) had anastomotic leakage. Median follow-up duration was 16 (range, 3 - 29) months. Up to now, one patient developed recurrence (5.3%). Acceptable anal function results were obtained in most patients.
CONCLUSIONSCurability and anal function was obtained by PIDCA combined with preoperative or postoperative radiotherapy and postoperative chemotherapy. PIDCA is ideal and safe for selected patients with tumor located below 5 cm from the anal verge.
