- Early assessment of bilateral inguinal hernia repair: A comparison between the laparoscopic total extraperitoneal and Stoppa approaches(2016) UTIYAMA, Edivaldo Massazo; DAMOUS, Sergio Henrique Bastos; TANAKA, Eduardo Yassushi; YOO, Jin Hwan; MIRANDA, Jocielle Santos de; USHINOHAMA, Adriano Zuardi; FARO JR., Mario Paulo; BIROLINI, Claudio Augusto ViannaBACKGROUND: The present clinical trial was designed to compare the results of bilateral inguinal hernia repair between patients who underwent the conventional Stoppa technique and laparoscopic total extraperitoneal repair ( LTE) with a single mesh and without staple fixation. PATIENTS AND METHODS: This controlled, randomised clinical trial was conducted at General Surgery and Trauma of the Clinics Hospital, Medical School, the University of Sao Paulo between September 2010 and February 2011. Totally, 50 male patients, with a bilateral inguinal hernia, older than 25 years were considered eligible for the study. The following parameters were analysed during the early post-operative period: ( 1) The intensity of surgical trauma, operation time, C-reactive protein ( CRP) levels, white blood cell count, bleeding and pain intensity; ( 2) quality of life assessment; and ( 3) post-operative complications. RESULTS: LTE procedure was longer than the Stoppa procedure ( 134.6 min +/- 38.3 vs. 90.6 min +/- 41.3; P < 0.05). The levels of CRP were higher in the Stoppa group ( P < 0.05) but the number of leucocytes, haematocrit, and haemoglobin were similar between the groups ( P > 0.05). There was no difference in pain during the 1st and 7th post-operative, physical functioning, physical limitation, the impact of pain on daily activities, and the Carolinas Comfort Scale during the 7th and 15th post-operative ( P > 0.05). Complications occurred in 88% of Stoppa group ( 22 patients) and 64% in LTE group ( 16 patients) ( P < 0.05). CONCLUSION: The comparative study between the Stoppa and LTE approaches for the bilateral inguinal hernia repair demonstrated that: ( 1) The LTE approach showed less surgical trauma despite the longer operation time; ( 2) Quality of life during the early post-operative period were similar; and ( 3) Complication rates were higher in the Stoppa group.
- Polypropylene and polypropylene/polyglecaprone (Ultrapro(r)) meshes in the repair of incisional hernia in rats(2015) UTIYAMA, Edivaldo Massazo; ROSA, Maria Beatriz Sartor de Faria; ANDRES, Marina de Paula; MIRANDA, Jocielle Santos de; DAMOUS, Sérgio Henrique Bastos; BIROLINI, Cláudio Augusto Vianna; DAMOUS, Luciana Lamarão; MONTERO, Edna Frasson de SouzaPURPOSE: To compare the inflammatory response of three different meshes on abdominal hernia repair in an experimental model of incisional hernia. METHODS: Median fascial incision and skin synthesis was performed on 30 Wistar rats. After 21 days, abdominal hernia developed was corrected as follows: 1) No mesh; 2) Polypropylene mesh; and, 3) Ultrapro(r) mesh. After 21 days, the mesh and surrounding tissue were submitted to macroscopic (presence of adhesions, mesh retraction), microscopic analysis to identify and quantify the inflammatory and fibrotic response using a score based on a predefined scale of 0-3 degrees, evaluating infiltration of macrophages, giant cells, neutrophils and lymphocytes. RESULTS: No significant difference was seen among groups in adherences, fibrosis, giant cells, macrophages, neutrophils or lymphocytes (p>0.05). Mesh shrinkage was observed in all groups, but also no difference was observed between polypropylene and Ultrapro mesh (7.0±9.9 vs. 7.4±10.1, respectively, p=0.967). Post-operatory complications included fistula, abscess, dehiscence, serohematic collection and reherniation, but with no difference among groups (p=0.363). CONCLUSION: There is no difference between polypropylene (high-density) and Ultrapro(r) (low-density) meshes at 21 days after surgery in extraperitoneal use in rats, comparing inflammatory response, mesh shortening, adhesions or complications.
- Uterine cancer presenting as obstructive jaundice(2016) MANUEL, Valdano; ROCHA, Eserval; FORTINI, Giovana; PASCOAL, Zeida; NETTO, Renata; RENGEL, Lenira; BIROLINI, Claudio; UTIYAMA, Edivaldo MassazoObstructive jaundice as an initial manifestation of uterine cancer is extremely rare. We present a case of a 72-year-old female who presented with obstructive jaundice, supposedly for pancreatic cancer. After detailed diagnostic investigation, the cause of the jaundice was attributed to a metastatic compression of the common bile duct, from the primary neoplasm of the uterus. This case highlights the importance of including uterine cancer in the differential diagnosis of woman presenting with obstructive jaundice, even though it is very rare.
- Great saphenous vein aneurysm: A differential diagnosis of femoral hernia and review(2015) MIRANDA, Jocielle Santos de; DAMOUS, Sergio Henrique Bastos; FARO JUNIOR, Mario Paulo; YOO, Jin Hwan; YASSUSHI, Eduardo Tanaka; ZUARDI, Adriano; MURAKAMI, Abel Hiroshi; BIROLINI, Claudio; UTIYAMA, Edivaldo MassazoINTRODUCTION: Venous aneurysms are unusual clinical entities that might be difficult to diagnose and usually appear as an asymptomatic incidental finding on physical examination or imaging study and discovered only during the surgical exploration. They are important differential diagnosis of groin and other subcutaneous mass. PRESENTATION OF CASE: We report a case of a 67-years-old woman who had a groin mass misdiagnosed as femoral hernia, which was subsequently diagnose as great saphena vein aneurysm in the intraoperative set and treated with ligature and resection. DISCUSSION: In conclusion, venous aneurysms of the superficial system are lesions that are important differential diagnosis of groin and other subcutaneous mass. CONCLUSION: Diagnosis is readily available by duplex ultrasonography; however, in most cases, the diagnosis is done only in the operative field. (C) 2015 The Authors.
- Does a bilateral polypropylene mesh alter the duct deferens morphology, testicular size and testosterone levels? Experimental study in rats(2020) DAMOUS, Sergio Henrique Bastos; DAMOUS, Luciana Lamarao; MIRANDA, Jocielle dos Santos; MONTERO, Edna Frasson de Souza; BIROLINI, Claudio; UTIYAMA, Edivaldo MassazoPurpose: To evaluate the effect of a PP mesh on duct deferens morphology, testicular size and testosterone levels. Methods: Forty adult male rats were distributed into groups: 1) no surgery; 2) inguinotomy; 3) mesh placed on the duct deferens; and 4) mesh placed on the spermatic funiculus. After 90 postoperative days, the inguinal region was resected, and blood samples were collected for the measurement of serum testosterone (pg/dl). The ducts deferens were sectioned in three axial sections according to the relationship with the mesh - cranial, medial and caudal. The wall thickness and duct deferens lumen area were measured. Results: The morphology of the duct deferens was preserved in all groups. The mesh placement did not alter this morphology in any of the analyzed segments. Surgery, with or without mesh placement, did not alter the morphology, wall thickness or lumen area (p>0.05). In all operated groups, serum testosterone levels were similar (p>0.05) but there was a decrease in testicle size (p<0.05). Conclusion: Surgery, with or without mesh placement, did not alter the morphology of the duct deferens and, although this treatment resulted in testicular size reduction, it did not affect serum testosterone levels.
- Temporary abdominal closure with zipper-mesh device for management of intra-abdominal sepsis(2015) UTIYAMA, Edivaldo Massazo; PFLUG, Adriano Ribeiro Meyer; DAMOUS, Sérgio Henrique Bastos; RODRIGUES-JR, Adilson Costa; MONTERO, Edna Frasson de Souza; BIROLINI, Claudio Augusto ViannaOBJECTIVE: to present our experience with scheduled reoperations in 15 patients with intra-abdominal sepsis. METHODS: we have applied a more effective technique consisting of temporary abdominal closure with a nylon mesh sheet containing a zipper. We performed reoperations in the operating room under general anesthesia at an average interval of 84 hours. The revision consisted of debridement of necrotic material and vigorous lavage of the involved peritoneal area. The mean age of patients was 38.7 years (range, 15 to 72 years); 11 patients were male, and four were female. RESULTS: forty percent of infections were due to necrotizing pancreatitis. Sixty percent were due to perforation of the intestinal viscus secondary to inflammation, vascular occlusion or trauma. We performed a total of 48 reoperations, an average of 3.2 surgeries per patient. The mesh-zipper device was left in place for an average of 13 days. An intestinal ostomy was present adjacent to the zipper in four patients and did not present a problem for patient management. Mortality was 26.6%. No fistulas resulted from this technique. When intra-abdominal disease was under control, the mesh-zipper device was removed, and the fascia was closed in all patients. In three patients, the wound was closed primarily, and in 12 it was allowed to close by secondary intent. Two patients developed hernia; one was incisional and one was in the drain incision. CONCLUSION: the planned reoperation for manual lavage and debridement of the abdomen through a nylon mesh-zipper combination was rapid, simple, and well-tolerated. It permitted effective management of severe septic peritonitis, easy wound care and primary closure of the abdominal wall.
