Comparison of the Clinical Effect of Conformal Sphincter Preservation Operation and Transsphincter Interrectal Resection in Patients with Low Rectal Cancer
Objective:To analyze and compare the therapeutic effects of conformal sphincter preservation operation(CSPO)and transsphincter interrectal resection in patients with low rectal cancer.Method:A total of 96 patients with low rectal cancer admitted to the Gastroenterology and Anorectal Surgery Department of Zaozhuang Municipal Hospital from March 2021 to March 2023 were selected and divided into two groups according to random number table method,with 48 patients in each group.The control group underwent transsphincter interrectal resection,and the observation group underwent CSPO.Follow-up was performed until 3 months after surgery.Operation-related indexes,anal function,quality of life and complications were compared between the two groups.Result:There were no statistically significant differences in intraoperative bleeding volume and number of lymph node dissection between the two groups(P＞0.05).The operation time in the observation group was(171.63±11.57)min,the anal exhaust time was(2.26±0.75)d and the hospital stay was(6.21±1.35)d,which were shorter than(203.58±14.29)min,(4.71±1.24)d and(8.69±1.84)d in the control group,respectively,the incidence of complications in the observation group was 4.17%(2/48),lower than 18.75%(9/48)in the control group,the differences were statistically significant(P＜0.05).Before surgery,there were no statistically significant differences in the maximum toler-able volume(MTV),rectal resting pressure(RRP),and maximum squeeze pressure(MSP)and the various dimensions of the World Health Organization quality of life scale(WHOQOL-BREF)between the two groups(P＞0.05);after surgery,the MTV of the observation group was(181.50±17.25)mL,the MSP was(129.85±10.45)mmHg,the scores of each dimension in the WHOQOL-BREF were(70.21±3.62),(75.83±4.29),(77.49±3.46),and(76.29±3.98)points,respectively,which were higher than(159.71±15.82)mL,(113.42±8.31)mmHg,(65.38±2.97),(68.96±3.01),(69.35±2.97),and(67.42±3.28)points in the control group,the RRP of the observation group was(8.48±1.46)mmHg,lower than(10.21±2.06)mmHg of the control group,the differences were statistically significant(P＜0.05).Conclusion:Compared with transsphincter interrectal resection,CSPO has a shorter operation time,can maximize the preservation of anal function,promote postoperative recovery of patients,improve quality of life,and fewer complications.
