ABSTRACT
Objective:To investigate the application value of Prolene thread-needle continuous suture method in pancreaticojejunostomy pancreaticoduodenectomy.Methods:The clinical data of 80 patients with preoperative diagnosis of periampullary tumors undergoing pancreaticoduodenectomy who were admitted to Shanxian Central Hospital of Heze City from January 2017 to December 2020 were selected. According to the different methods of anastomosis, 80 patients were divided into A group and B group, each group with 40 patients, the patients in A group were performed pancreatic duct-mucosal anastomosis and the patients in B group were performed Prolene thread-needle continuous suture. The preoperative clinical data, operation-related data, postoperative complications in two groups were compared.Results:There were no statistically significant differences between the two groups in clinical data such as gender, age, albumin level, pancreatic duct diameter, combined underlying diseases, preoperative bilirubin, admission symptoms, preoperative biliary drainage and tumor location ( P>0.05).The operation time, intraoperative blood loss, postoperative drainage, operation durationand postoperative hospital stay in B group were lower than those in A group : (353.64 ± 95.28) min vs. (395.38 ± 110.29)min, (330.19 ± 100.27) ml vs. (397.43 ± 105.97) ml, (330.57 ± 110.68) ml vs. (376.18 ± 94.73) ml, (20.74 ± 8.08) min vs. (31.06 ± 7.83) min, (18.72 ± 6.02) d vs. (23.79 ± 7.41) d, the differences were statistically significant ( P<0.05). The incidence of complications such as pancreatic leakage, pancreatic fistula, abdominal infection, lung infection, biliary fistula and delayed gastric emptying in B group were lower than those in A group : 10.0%(4/40) vs. 20.0%(8/40), 7.5%(3/40) vs. 20.0%(8/40), 2.5%(1/40) vs. 12.5%(5/40), 0 vs. 7.5%(3/40), 5.0%(2/40)vs. 17.5%(7/40), 7.5%(3/40) vs. 17.5%(7/40), the differences were statistically significant ( P<0.05). Conclusions:Prolene thread-needle continuous suture method in pancreaticojejunostomy pancreaticoduodenectomy has the characteristics of simple operation, effective shortening of operation time, reliable anastomosisand can reduce the risk of postoperative pancreatic fistula complications.
ABSTRACT
objective To explore a reasonable treatment for upper eyelid shrinking. Methods All 15 patients with upper eyelid retrac-tion were divided in group A,group B and group C. Group A with 9 eyes received botulinum toxin type A,group B with 10 eyes were corrected by central aponeurosis disinsertion,group C with 9 eyes upper eyelid were corrected by the lengthening of the levator muscle and Müller's muscle. And the data was summarized and analyzed. Results Five cases (9 eyes) with upper eyelid shrinking obviously were improved 72 h after injecting botulinum toxin type A,but the eyelids returned to previous states 4~6 months later. The shape of postoperative eyelid was good and the eyelids structure was natural in group B,recurrence was in 2 cases. Patients in group C had satisfactory results. And there was no recurrence and complications after 3~24 months of follow-up. Conclusion The three treatments have effect on upper eyelid shrinking at quiescence phase. The method of injecting botulinum toxin type A is simple,with reliable curative effect and short duration,while it was nee-ded repeated injections. The method of central aponeurosis disinsertion is simple but difficult to quantify properly. The lengthening of the leva-tor muscle is not only simple but also with reliable effect and less complications.
ABSTRACT
To investigate the clinical application of the scrotal flap on penis lengthening. One hundred and fifty-two patients were operated using the scrotal flap from July 1998 to January 2008 at the Department of Plastic and Aesthetic, Surgery Southwest Hospital, Chongqing, China. The procedure consisted of designing a positive sign shaped incision 1.5cm above the root of the penis, dissect and release the superficial suspensory ligament and part of the deep suspensory ligament, then cover the elongated cavernosum with proper scrotal flap. Six-month to 5-year follow-up showed that all patients were satisfied with the good contour and function of the penis. The operation was successful. The method of using scrotal flap on penis lengthening has the following advantages: simple operation, reliable blood supply of the flap, one-stage operation, and satisfactory postoperative results. It is a preferable operation technique for penis lengthening

Objective To explore the effect of MMP-1, TIMP-1 on burn wound healing and hypertrophic scar (HS) forming. Methods Normal human full-thickness skin grafts were transplanted to the back of nude (athymic) mice, after these grafts survived, deep Ⅱ degree burn wounds were made in the middle of these grafts. During the process of burn wound healing and HS formation, the expressions of MMP-1 and TIMP-1 were detected by immunohistochemical staining. Results MMP-1 expression was first noted by day 2 after burns and became more prominent from day 3 to day 15, and then decreased rapidly. Immunostaining for MMP-1 was markedly increased at boundary regions marked by connective tissue fluidity. Immunoreactive TIMP-1 was also detected by day 2 but rapidly assumed the same interface expression pattern as described for MMP-1. Compared with MMP-1, immunostaining of TIMP-1 was irregular, but was obvious around vascular tissues. Conclusions The balance between MMP-1 and TIMP-1 during the inflammation and granulation phases might be important for the regulation of collagen proteins degradation. Within the remodeling phase, the inhibition of MMP-1 by TIMP-1 and the decrease of collagen degradation might lead to HS forming. The striking immunolocalization of MMP-1 and TIMP-1 to epithelial-dermal, eschar-dermal, and vascular-dermal interfaces suggested that they might play a particularly significant role at boundary regions marked by connective tissue fluidity.
