Objective To discuss whether age has an influence on short-term effect of intersphincteric resection (ISR) for elderly (≥75 years old) patients with ultra-low rectal or canal cancer or not. Methods From February 2016 to February 2017, 196 patients with ultra-low rectal or canal cancer received ISR in the Gastrointestinal Surgery Center of West China Hospital were eligible to include in this study, then they were divided into ≥75 years old group and <75 years old group according to the patients’ age. The intraoperative index, postoperative index, and complications rate were compared between these two groups. Results There were 113 cases in the ≥75 years old group, 83 cases in the <75 years old group, the baselines such as the gender composition, body mass index, tumor histology type, differentiation degree, tumor size, and distance from the anal margin had no significant differences ( P>0.05), but the preoperative anaesthetized ASA grade, proportions of pulmonary insufficiency, hypoproteinemia, anemia, hypertension, diabetes, and cardiac insufficiency of the ≥75 years old group were significantly higher than those of the <75 years old group (P<0.05). The operative time, intraoperative bleeding, and total complications rate had no differences between these two groups (P>0.05), the first exhaust time, the first eating time, the first defecation time, the first ambulation time, and hospitalization time of the ≥75 years old group were significantly longer than those of the <75 years old group (P=0.023, 0.037, 0.019, 0.020, and 0.012, respectively). There were no significant differences in the incidences of the anastomotic leakage, perianal infection, intestinal obstruction, and wound infection between these two groups (P>0.05). All the 196 patients were followed-up with an average follow-up of 7 months, there were 4 cases of recurrent patients, of which 3 were in the ≥75 years old group and 1 in the <75 years old group; there were 3 cases of death, of which 2 were in the ≥75 years old group and 1 in the <75 years old group. Conclusions Short-term recovery of elderly patients with ultra-low rectal or canal cancer is slower than younger patients because of poor preoperative conditions. ISR surgery is still safe and effective for elderly patients with ultra-low rectal or canal cancer and postoperative complications rate has no obvious increase, but it needs a surgeon’s skilled operation technology and multi-disciplinary team cooperation.
Objective To compare the postoperative anorectal pressure after procedure for prolapse and hemorrhoids (PPH) and Milligan-Morgan hemorrhoidectomy (MMH) in treatment of patients with mixed hemorrhoid of Ⅲ-degree. Methods In total of 112 patients with mixed hemorrhoid of Ⅲ-degree who underwent PPH (n=60) or MMH (n=52) in The First Affiliated Hospital of Xinjiang Medical University between March 2014 to March 2015 were prospectively enrolled, the type of surgery was according to patients’ individual choice. In 6 months after operation, all patients under-went the examination of anorectal manometry which including rectal anal inhibitory reflex, rectal resting pressure, anal resting pressure, maximal anal contractive pressure, and anal canal length of high pressure belt. Results In 6 months after operation, the positive rate of rectal anal inhibitory reflex 〔88.3% (53/60) vs. 61.5% (32/52)〕 , anal resting pressure 〔(56.42± 2.25) mm Hg vs. (46.31±2.58) mm Hg〕, and anal canal length of high pressure belt 〔(3.35±0.12) cm vs. (2.29±0.23) cm〕 of PPH group were all significantly higher than those of MMH group (P＜0.05), but there was no statistical significance between PPH group and MMH group in rectal resting pressure 〔(5.51±1.26) mm Hg vs. (5.39±1.85) mm Hg〕 and maximal anal contractive pressure 〔(156.64±9.78) mm Hg vs. (155.32±8.53) mm Hg〕, P>0.05. Conclusion PPH and MMH are all effective to treat mixed hemorrhoids of Ⅲ-degree, but PPH is more positive in protection of anal function.
ObjectiveTo observe the effect of procedure for prolapse and hemorrhoids (PPH) combined with partial internal anal sphincterotomy (Abbreviated as combined therapy) in the treatment of severe mixed hemorrhoids complicated with high rectal and anal canal resting pressure.MethodsFrom January 2016 to June 2018, the patients with grade Ⅲ–Ⅳ mixed hemorrhoids who underwent surgical treatment in this hospital were selected for the prospective study, including 100 patients with high pressure (>70 mm Hg, 1 mm Hg=0.133 kPa) and 100 patients with low pressure (≤70 mm Hg), then which were divided into an experimental group and a control group according to the random number table method (with 50 cases in each group). The patients in the control group underwent the PPH and in the experimental group underwent the combined therapy. The therapeutic effect and perioperative indicators were observed in each group, Visual Analogue Scale (VAS) was used to evaluate the degree of pain before and after the operation, the incidence of complications and the recurrence rate of symptoms were observed, the factors influencing the therapeutic effect of combined therapy were analyzed.ResultsWhether for the patients with high or low rectal and anal canal resting pressure, although the operation time of the experimental group was significantly longer than that of the control group (t=8.996, P<0.001; t=8.927, P<0.001), the total effective rate was higher (χ2=7.294, P=0.007; χ2=6.775, P=0.009), the length of stay in hospital was shorter (t=11.922, P<0.001; t=11.442, P<0.001), the hospital expenses decreased significantly (t=2.226, P=0.028; t=2.562, P=0.012), the VAS score at 24 h and 72 h after operation were lower (24 h: t=12.659, P<0.001; t=12.191, P<0.001; 72 h: t=9.920, P<0.001; t=9.901, P<0.001), the incidence of postoperative complications was lower (χ2=7.484, P=0.006; χ2=11.416, P=0.001) in the experimental group as compared with the control group; there was no significant difference between the two groups (χ2=1.042, P=0.307; χ2=0.211, P=0.646). The course of disease and the grade of internal hemorrhoids were the independent factors influencing the marked efficiency of combined therapy (χ2=7.417, P=0.009; χ2=4.286, P=0.017).ConclusionsCombined therapy is effective in treatment of severe mixed hemorrhoids complicated with high rectal and anal canal resting pressure, it could accelerate recovery of patients and relieve pain. It should be paid attention to patients with long course of disease and severe degree of internal hemorrhoids.
ObjectiveTo study the advance of malignant anorectal melanoma. MethodsThe literature in recent years about risk factors,clinical characteristic,early diagnosis,treatment and the prognosis of the anorectal melanoma were reviewed.ResultsMalignant anorectal melanoma was very rare.The history of pigment naevus,human immunodeficiency virus infection and sunlight exposure might be the risk factors.Clinic characteristics were rectal bleeding,anorectal mass and changing in bowel habits.Early diagnosis mainly depended on performing routine examination on patients between the ages of 45-80 years.The staining for polycolnal CEA in anorectal melanoma has a role on diagnostic pathology.The treatment is controversial and the combined treatments of chemotherapy with radiation therapy and immunotherapy which were based on surgery (abdominoperineal resection or wide local excision) are introduced.Conclusion Early diagnosis of malignant anorectal melanoma is difficult and the prognosis is poor.It is necessary to pay more attention to this disease and the most successful therapeutic approaches need to be developed.

Objective To investigate the safety and feasibility of the total mesorectal excision （TME） and intersphincteric resection （ISR） for ultra-low rectal cancer and anal sphincter preservation surgery for anorectal cancer， and to evaluate the short term efficacy and postoperative anal function. Methods A retrospective analysis of clinical and follow-up data of 86 cases with TME＋ISR for ultra-low rectal cancer and anorectal cancer from January 2009 to December 2010 in West China Hospital of Sichuan University were performed. Results Eighty-six patients were successfully performed the operation， the lower edge of tumor from the anus was 1-5 cm （average 1.63cm）； tumor diameter was 2-7 cm （average 3.4cm）. The tumors were high differentiation in 4 cases， moderately differentiation in 60 cases，and poorly differentiation in 22 cases. The pTNM stages were stageⅠin 12 cases， stageⅡA in 11 cases， stage ⅡB in 15 cases， stage ⅢA in 2 cases， stage ⅢB in 23 cases， stage ⅢC in 16 cases， and stage Ⅳ in 7 cases. There were postoperative anastomotic leakage in 3 cases， perianal infection in 2 cases （1 case received reoperation with permanent colostomy because of pelvic peritoneal infection caused by perianal severe infections）. Anastomotic bleeding and anastomotic stenosis were of 2 cases respectively. Rectovaginal fistula， inflammatory ileus， urinary retention， and abdominal infection were of 1 case respectively. Eighty-six patients were followed-up for 12-24 months， the mean time was 18 months. Liver metastases was found in 1 case in 7 months after operation， 2 cases dead in the 7th month and 12th month after operation respectively. Local recurrence were found in 3 cases （3.5%） in 1 year after operation. The survival rate of 1-year was 97.7% （84/86）. The times of defecation was 1-5 times a day. The Kirwan’s score level on function of control defecation was 1-2 grade. Conclusions TME＋ISR for low rectal cancer and anorectal cancer is a viable， safe， and radical operation type for preservation of anus. The short term efficacy is satisfactory.

ObjectiveTo investigate effect of preoperative three-dimensional anorectal endosonography (3D-AREUS) in anal fistula surgery.MethodsA total of 100 patients with anal fistula who were admitted to the Chaoyang Central Hospital from December 2017 to December 2018 were included prospectively, then were randomly divided into ultrasound group and control group with 50 cases in each group. The preoperative examination was performed by 3D-AREUS in the ultrasound group, and preoperative routine examination, finger examination or probe exploration were performed in the control group. The postoperative recurrence and anal functions were compared between the two groups.ResultsThere were no statistically significant differences in the gender, age, body mass index, anal surgery history, preoperative anal function, etc. between the two groups (P>0.05). The detection rate of branch fistulas in the ultrasound group was significantly higher than that in the control group (P=0.025). For the patients with complex anal fistula, compared with the control group, the location accuracy rate of internal opening was higher (P=0.014), the change value of preoperative and postoperative fecal incontinence score was lower (P=0.039), anorectal pressure status (resting pressure of anal canal, anal systolic pressure, and length of anal high pressure zone) were lower (P<0.05) in the ultrasound group; For the patients with simple anal fistula, which had no significant differences between the ultrasound group and control group (P>0.05). There were 4 cases of recurrence in each group.ConclusionsFor complex anal fistula, preoperative 3D-AREUS could clarify position of internal opening, presence of branching fistula, and the relationship between fistula and sphincter, so as to make accurate surgical plans, reduce secondary injuries, and retain postoperative anal function of patients.
