  ABSTRACT: ObjectiveTo assess the use of gluteus maximus muscle to reconstruct the anal sphincter for very low rectal cancer. This study aimed to evaluate the local recurrence and function of the new anal sphincter after operation. MethodsSixteen patients underwent the replacement operation, and then received biofeedback treatments 1 month after the operation. The therapeutic responses were evaluated using the Vaizey and Wexner scoring systems and vectorial manometry. The controls were 30 cases who had undergone a low anterior resection for rectal cancer and 30 healthy people. ResultsMedian follow-up was 4.2 years. No local recurrence was observed. The Vaizey and Wexner scores and vectorial manometry 1 month after operation were significantly lower than those of the healthy and low anterior resection controls (P <0.001). After biofeedback treatments, the above indexes improved significantly (P <0.001), especially after 1 year (P <0.001), but still remained lower than the controls(P <0.001). The rectoanal reflex only increased to 31.3 % 1 year after operation. ConclusionThe local recurrence after the replacement operation was low. The defecation function was poor early after operation, but increased markedly after biofeedback treatments and long-term functional exercise. This therapy can be one choice for very low rectal cancer.

  ABSTRACT: ObjectiveSpontaneous rupture is an uncommon complication of primary hepatocellular carcinoma (HCC). There is no standard method of treatment, and most often treatment depends on the condition of the patient or the assessment by the surgeon. The aim of this study was to evaluate our experience of emergency laparotomy in the management of spontaneous rupture of HCC. MethodsRetrospective analysis documented 49 rupture HCC cases who received emergency laparotomy from Oct. 1990 to Oct. 2006. ResultsThirty-nine cases (79.6%) had a history of hepatitis and 39 cases (79.6%) were accompanied with liver cirrhosis. The most frequent manifestation which was present in 47 cases (95.9%) was sudden right hypochondrial or epigastric pain. Shock was seen in 40 cases (81.6%), and 42 cases (85.7%) had signs of peritonitis. The methods of operation were performed in the number of cases as follows: suture in 5; packing in 2; hepatic artery ligation in 4; hepatectomy in 21; microwave coagulation in 5; microwave coagulation combined with packing in 3; microwave coagulation combined with hepatic artery ligation in 9. Morbidity occurred in 11 cases (22.4%). The overall hospital mortality rate was 10.2%. The mean survival time was 8.8 months. The main causes of death were liver failure and massive variceal bleeding. ConclusionSpontaneous rupture of HCC represents a life-threatening condition with an overall poor prognosis. Laparotomy should be the first choice for treating HCC rupture if the proper conditions are present. Liver failure is the vital condition influencing the prognosis.

  ABSTRACT: Abdominoperineal resection has been the standard procedure for low rectal cancer. The present study details a new technique, partial longitudinal resection of the anorectum and sphincter, and assesses the oncological and functional outcomes. Between January 2004 and April 2008, 12 patients underwent partial longitudinal resection of the anorectum and sphincter for low rectal cancer. All patients underwent a diverting ileostomy and received biofeedback training before stoma closure. Functional results were assessed by vector manometry, Wexner constipation score and Wexner incontinence score. The quality of life (QoL) was assessed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30). There was no postoperative mortality and a R0 curative resection was confirmed in every case. Morbidity included anastomotic leakage in three patients, one of whom underwent reoperation, and stenosis in 11, which was successfully managed with dilatation. The patient who underwent reoperation was not included in the functional analysis. The 11 successful patients received biofeedback training for 1-4 months, and underwent ileostomy closure 6-12 months after surgery. No patient had severe faecal incontinence after stoma closure. The EORTC QLQ-C30 global health status and QoL scores at 12 months after stoma closure were 50.4 ± 24.3, similar to preoperation scores of 52.3 ± 25.6 (P = 0.927), and not significantly different to scores for the healthy control population of 63.4 ± 23.5 (P = 0.539). No patients developed local recurrence during the median observation period (35.5 months). One patient had distant metastases at 24 months, and underwent resection of the left liver. Curability and acceptable anal function can be obtained by partial longitudinal resection of the anorectum and sphincter in patients with very low rectal cancers. This technique is recommended as an alternative to abdominoperineal resection in patients with external sphincter muscle invasion or tumours located below the dentate line.
