RESUMEN

BACKGROUND: The study aims to evaluate the efficacy of resorbable clips in polydioxanone in laparoscopic surgery. METHODS: The authors report their personal experience regarding the use of Absolok (ABL) resorbable clips in laparoscopic surgery. Out of a total of 745 laparoscopic operations performed from September 1992 to February 1997, 438 included the use of resorbable clips in place of metal clips, both for cystic duct section during cholecystectomy and vascular structures, or to lock continuous sutures. ABL clips were also used for major vessels (e.g. mesenteric artery) during laparoscopic colic resections. RESULTS: In all cases when they were used, ABL never gave rise to complications, such as biliary outflow or hemorrhage caused by the dislocation of the clips themselves. CONCLUSIONS: The authors conclude by affirming the value and safety of this type of clip.

RESUMEN

Three cases of posttraumatic splenic laceration in young patients are reported. In each case, hemostasis of the lesion was obtained by the use of microfiber collagen in emergency laparoscopy. In two cases, complete hemostasis was achieved and the entire organ was saved. In the third case, splenectomy proved necessary after renewed bleeding occurred.

RESUMEN

Described here is a case of constriction of the ileal loop caused by a volvulus forming on an internal hernia through the mesenteric opening in the anastomotic colonic stumps, following left laparoscopic-assisted hemicolectomy. This experience indicates the need for closure of mesenteric gaps with a continuous suture after laparoscopic-assisted left hemicolectomy.

RESUMEN

The authors describe three cases of systemic lupus erythematosus (SLE) associated with Kikuchi's histiocitic necrotizing lymphadenitis (HNL). Two patients presented a cytomegalovirus infection concomitantly with Kikuchi's lymphadenitis; in one of them the onsets of SLE and HNL were simultaneous. In the third case an inguinal HNL was concomitant with vaginitis of unknown aetiology.

RESUMEN

The Authors present cases of groin hernioplasty using the Shouldice method; the method used for more than six years, such as elective technique to treat groin hernia, is evaluated on the basis of results of complications and recurrences. A careful clinical check of patients operated on over one year at least, allows confirmation of the efficiency of the method, because it results in a low percentage of recurrence and complications, plus a low social and economical cost. For these reasons it is proposed that the method is applied in day surgery.

RESUMEN

The paper describes a case of gastric myoblastoma, a rare tumour of the smooth musculature most commonly found in the stomach but also encountered outside the digestive tract. The tumour is potentially malignant and the occasional malignant forms feature histologically a large number of clearly atypical mitoses and clinically an aggressive pattern often involving even widespread metastasis. The case presented is that of a 73 year old woman given a Billroth I gastric resection who was in perfect health 7 months later despite the findings of a myoblastoma with some signs of enhanced mitosis.

RESUMEN

Two cases of adenocarcinoma of the vermiform appendix are described. The literature on these rare cancers which are almost always diagnosed at routine histology and whose prognosis is related to Duke grading and staging, is reviewed. The stable cure observed in one patient after 13 years after straightforward caecal resection for cancer of the appendix extending beyond the base of the implant (which today would be handled with hemicolectomy) and then treated for multiple polyps, two of them in a stage of malignant degeneration, suggests a difference of biological behaviour compared to tumours of the other colon districts. In the second case, stress is laid on the unusual extension of the tumour-related inflammation to the skin of the gluteal region.

RESUMEN

Among 197 pancreatic and periampullar tumours operated between 1970 and 1979, an associated cystic of pseudocystic lesion was found on 15 occasions (a rate of 16%). In 10 cases it was a question of pseudocysts located at the bodytail, while the tumour occupied a distinct site (periampullar tumour or carcinoma of the head); in 5 cases the cavitary lesion coincided with the tumour (2 endocrine tumours of the head, 2 cystoadenocarcinomas and one adenocarcinoma of the body-tail). In 6 cases (of which 5 operated) the error in diagnosis led to misappreciation of the tumour: only 3 of these cases could be treated with radical surgery. In the other 9, correct diagnosis was possible from the start and in 6 radical surgery was performed. Stress is placed on the need for prompt and early diagnosis, in order to allow adequate treatment of the tumour in line with the canons of radical action.

RESUMEN

The authors discuss the main features of the complex pathophysiology of patients subjected to duodenocephalopancreatectomy, and particularly the difficulties inherent in clinical assessment of the digestive and metabolic impairment consequent upon the duodeno-gastro-pancreatic mutilation. Out of a total of 57 cases of this description, they singled out for recheck 23 patients who had undergone duodenocephalopancreatectomy not less than six months and not more than seven years before (chronic pancreatitis, 11 cases; various malignancies of the periampullar area, 10 cases; Zollinger-Ellison syndrome, 1 case; retroperitoneal lymphoma, 1 case). Seventy-six per cent of patients who had been gainfully employed were able to resume their jobs after surgery. Steatorrhea, assessed in terms of fecal fats, was present in all cases; notwithstanding, 70% of the patients gained weight (average increase 7 kg). All patients were on enzyme replacement therapy. Only 4% developed diabetes, and none developed postoperative peptic ulcers. Conversely there was a high incidence (65%) of bone structure reshuffling, signally osteoporosis, probably imputable to steatorrhea and vitamin D malabsorption, plus the often associated increase of serum alkaline phosphatase activity.

RESUMEN

Among 45 operations for pseudocysts the authors report 9 cases of complications, three of them early (haemorrhage and acute pancreatic necrosis) and six delayed (persistence of fistulae and relapse); in six of these surgery was performed and two of them died. Among the different types of surgery performed, external drainage proved to be the one most burdened by complications (2/3 of cases), while their incidence was far lower in internal shunt (2 cases out of 28) and cysto-parenchmal demolitions (one case out of eight). Attention is drawn to the danger of post-operative haemorrhage and the need to combat this complication with decision. For recurring pseudocysts and for fistulae which do not benefit from conservative treatment, the surgical operation, when it does not result in demolition, must be capable of correcting the canalicular alterations of the base pancreatitis.
