The Lichtenstein open tension-free inguinal hernia repair using a new prosthetic mesh-Bulgarian irresorbable ampoxen.

The routine use of mesh for repair of inguinal hernia has been popularized by Lichtenstein and coworkers. We adopted this technique and performed it widely using a mesh unknown in the Western world. Ampoxen [multifilamented polycaproamide, impregnated with 5-Nitro-8-Hydroxyquinolinum (Nitroxolinum, DCI), MEDICA, SA, Sandanski, Bulgaria] was discovered in 1975 and proved to be an excellent prosthetic material for replacement of attenuated or destroyed abdominal wall; furthermore, this mesh is very cheap and became widely applicable in our country. This report describes our experience with the first 846 adult inguinal hernia repairs under local anesthesia using Ampoxen. All 846 patients had excellent results, without recurrence. There were nine wound infections (1.1%), 16 testicular oedemas (1.9%), no seromata and no deaths. In no patient was the prosthetic mesh removed. There were no complications related to the use of Ampoxen; this mesh is permanent, has a great degree of fibrous tissue reaction, and wide spectrum antimicrobic activity. We advocate the Lichtenstein technique using irresorbable mesh (particularly Ampoxen) for all adult groin hernias except Types 1 and 2 (according to Nyhus' classification), and for all adult recurrent groin hernias.

Stercoral perforation of the colon.

An elderly man presented with abdominal pain and signs of peritonitis. Emergency laparotomy was performed and a stercoral perforation of the cecum was found with a large scybalum plugging the defect. The patient was treated with right colectomy and a stoma was formed from the terminal ileum and transverse colon. Stercoral perforation of the colon is extremely unusual and carries high morbidity and mortality. The etiology, diagnosis and treatment of the condition are briefly discussed.

Perforated nonspecific ulcer of the sigmoid colon: four cases in one year.

During 1993, four consecutive adult male patients underwent emergency surgery for free perforation of nonspecific sigmoid colon ulcers. All four patients presented with peritonitis and in each patient the Hartmann's procedure was performed. In each patient there was a single perforation but two of the patients presented with multiple erosions and ulcerations, and the other two- with solitary ulcers. All patients survived and had uneventful postoperative course. Three of them underwent uncomplicated restorations of the bowel continuity. Colonoscopy should be attempted in every suspicious case to confirm or to exclude the presence of nonspecific colon ulcers that could threat patient's life.

Ingested foreign bodies of the gastrointestinal tract: retrospective analysis of 542 cases.

Ingested foreign bodies (FBs) present a common clinical problem. As the incidence of FBs requiring operative removal varies from 1% to 14%, it was decided to perform this study and compare the data with those from the world literature, as well as to outline an algorithm for management, including indications for surgery. We reviewed all patients with FB ingestion from 1973 to 1993. There were 542 patients with 1203 ingestions, aged 15 to 82 years. Among them, 69. 9% (n = 379) were jail inmates at the time of ingestion, 22.9% (n = 124) had a history of psychosis, and 7.2% (n = 39) were alcoholics or denture-wearing elderly subjects. Most foreign bodies passed spontaneously (75.6%; n = 410). Endoscopic removal was possible in 19. 5% (n = 106) and was not associated with any morbidity. Only 4.8% (n = 26) required surgery. Of the latter, 30.8% (n = 8) had long gastric FBs with no tendency for distal passage and were removed via gastrotomy; 15.4% (n = 4) had thin, sharp FBs, causing perforation; and 53.8% (n = 14) had FBs impacted in the ileocecal region, which were removed via appendicostomy. Conservative approach to FB ingestion is justified, although early endoscopic removal from the stomach is recommended. In cases of failure, surgical removal for gastric FBs longer than 7.0 cm is wise. Thin, sharp FBs require a high index of suspicion because they carry a higher risk for perforation. The ileocecal region is the most common site of impaction. Removal of the FB via appendicostomy is the safest option and should not be delayed more than 48 hours.

Subcutaneous splenosis: a clue to diagnosis of thoracic splenosis.

We describe a unique case of combined thoracic and subcutaneous splenosis.

Abdominoperineal resection and perineal colostomy for low rectal cancer. The Lazaro da Silva technique.

PURPOSE: We sought to evaluate a new technique for creation of a continent perineal colostomy following abdominoperineal resection (APR) of the rectum for low rectal cancer. METHODS: Nine selected patients with low rectal cancer (two males; median age, 55.6 years; classified as Dukes A, 6 patients and as Dukes B, 3 patients) underwent APR. Following this, the original Lazaro da Silva technique was used as follows: 1) for performance of three circular myotomies in the distal sigmoid with a distance between each couple of no more than 8 cm; 2) repair of the myotomies, thus creating three circular colonic valves, the most distal of which remained extraperitoneally; 3) for construction of a perineal colostomy lying flush with the perineal skin; 4) after the patient starts consuming a regular diet, enemas through the perineal stoma are done, usually twice per week, to achieve defecation. Functional outcome was assessed by evaluation of bowel movements and neoanal continence. RESULTS: There were no deaths. From January 1994 until October 1995, no tumor recurrence has occurred, and fecal continence has been good. Four of the patients were able to defecate without enemas (2-4 times per week), and in five patients the self-administration of enemas (2-4 times a week) were necessary to accomplish defecation. CONCLUSION: Initial results with the Lazaro da Silva technique have been encouraging.
