Short bowel syndrome: clinical manifestations following extensive intestinal by-pass.

A personal experience with 43 cases of end-to-side jejunoileal bypass is reported. Two major clinical entities appear to emerge from the present study and in accordance with data from the literature: liver failure and the so-called enteric disease from bypass. Such observations were confirmed by the results obtained from an experimental investigation on 96 Wistar rats. The fact that the intestinal bacterial contamination seems to be the common cause of both effects and complications of intestinal bypass should limit by itself possible further developments of the procedure.

A modified Payne technique with a personal antireflux valvular system in the surgical treatment of morbid obesity.

Reflux into the blind loop in end-to-side jejuno-ileal bypass is commonly considered the cause of weight loss failure, but the lower morbidity and mortality suggest that this procedure should be preferred to end-to-end bypass in the surgical treatment of morbid obesity, with the proper technical modifications to prevent the reflux. An antireflux single or double valvular system created 3-6 cm proximally to the anastomosis, with few introverting seroserous stitches, parallel and perpendicular to the ileal axis, is reported. This technique, as compared to others, is not time consuming, is easily feasible and does not interfere with the blind loop down-flow. Comparative clinical data and x-ray controls demonstrated the value of this procedure which is able to give excellent results in cases where other procedures (gastric operations, bilio-intestinal, bilio-pancreatic bypass etc.), are contraindicated.

[Surgical treatment of severe obesity. Criteria of choice of operation. Personal technic].

The criteria underlying the choice of operation in a given case and the personal technique adopted are described. The technique in question is a personal modification of end-to-side jejuno-ileal bypass codified by Payne. To minimize reflux into the blind loop, a number of technical steps are considered indispensable: 1) fluted section of the jejunal stump; 2) isoperistaltic construction of the anastomosis and, particularly, 3) the creation of a single or double valve system upstream from the anastomosis by spiral introflexion of the mucosa using seroserous stitches parallel and perpendicular to the ileal lumen. Other techniques in use are reported. These are held to be extremely interesting but are not yet supported by a long enough follow-up.

[Jejuno-ileal bypass in the treatment of severe obesity: transverse or vertical approach?].

The criteria applicable to the selection of the approach route in the surgical management of essential gross obesity by means of a jejunal-ileal by-pass are discussed. Median vertical and transverse incision are compared in the light of early and late hypoxaemia in the immediate postoperative period; postoperative acidosis and alkalosis; rapidity; exposure; extendibility; tightness; postoperative pain; cosmetic results. A preference for the vertical approach is both stated and justified.

Sentinel lymph node biopsy to stage patients with cutaneous melanoma at the National Cancer Institute of Naples. Results from 240 sentinel node biopsies.

AIMS AND BACKGROUND: The presence of lymph node metastases in patients with cutaneous melanoma represents the basis for correct therapy planning and is the most powerful prognostic factor to evaluate overall survival at diagnosis. METHODS AND STUDY DESIGN: Since 1992, when Dr. Morton published his first experience, the sentinel lymph node (SLN) biopsy technique seems to have resolved this matter by correctly staging patients. We analyzed our data from 240 SLN biopsies performed in the last five years at the National Cancer Institute of Naples, evaluating the total identification rate and the nodal recurrence rate, and compared them with the preliminary data of the MSLT (melanoma sentinel lymph node trial). RESULTS: Of all SLNs evaluated 18.5% were micrometastatic and 14% were identified by immunohistochemical staining. Forty-one patients had metastatic SLNs and nodal dissection of the positive basins revealed no other tumor-positive lymph nodes in more than 80% of them. All patients with a Breslow thickness of less than 2 mm had micrometastases only in the SLN, while with increasing thickness two, three or more positive nodes were found. Among SLN-negative patients nine (4%) developed lymph node recurrence in the previously treated basin and were therefore considered as false negative SLN biopsies. CONCLUSIONS: The prognostic value of SLN biopsy needs to be confirmed by the final results of the MSLT evaluating the therapeutic use of this procedure in patients with a Breslow thickness of less than 2 mm and its possible impact on the course of the disease.

Prognostic value of sentinel node in oral cancer.

AIMS AND BACKGROUND: In stage I oral squamous cell carcinoma, clinical examination and imaging techniques are unable to identify 60-90% of patients at risk of micrometastasis, while the sentinel node biopsy technique allows to avoid the morbidity of elective neck dissection in patients not actually affected by micrometastases. MATERIALS AND METHODS: Forty-one T1-T2N0 patients underwent lymphoscintigraphy after peritumoral injection of human albumin labeled with 99Tc. Focal areas of radiotracer uptake were marked on the skin preoperatively. The sentinel lymph node (SLN) was identified by the combined use of blue dye and gamma probe and subsequently removed. Complete neck dissection was then performed in all patients and the histological findings were compared with those of SLN biopsy. RESULTS: The SLN was identified in 95% of the patients; in four cases (10%) two SLNs were isolated. In 18% of our patients the SLNs were located outside the expected drainage area. When the histology of the negative SLNs was compared with the pathological status of the neck dissection specimens no false negatives were found. Five SLNs in four patients contained micrometastases and were the only positive lymph nodes. CONCLUSIONS: SLN biopsy can be a valuable staging technique in T2 and T2 oral cancer with uninvolved neck in patients whose lymphatic drainage of the neck has not been altered by previous surgery or radiotherapy. It provides reliable detection of micrometastasis, indicating which level(s) should be removed ipsilaterally or contralaterally, and allows the surgeon to accurately plan neck dissection, taking into consideration the pattern of lymphatic drainage of each individual patient. In this way unnecessary neck dissection and its morphofunctional sequelae can be avoided in a considerable number of patients.

Drainage in thyroid surgery: a prospective randomised clinical study.

Drainage in thyroid surgery is still an area of controversy. We analysed the results of a prospective randomised trial conducted in our institution in order to assess the utility of drainage after thyroid surgery. Sixty patients were entered into the study, thirty of whom were drained after surgery and thirty who received no drainage. The two groups were well matched with regard to most characteristics. There was no difference between the two groups in terms of early or late postoperative complications. We therefore conclude that, in our experience, drainage after uncomplicated thyroid surgery is of no benefit.

Neoadjuvant chemotherapy for intermediate/high-grade soft tissue sarcomas: five-year results with epirubicin and ifosfamide.

BACKGROUND: Neoadjuvant chemotherapy for intermediate/high-grade soft tissue sarcomas (STS) may provide some advantages for facilitating the surgical resection of the tumor and for disease control. However its role as induction therapy before surgery should still be proved. PATIENTS AND METHODS: Twenty-one patients with intermediate/high-grade STS and tumor size > or = 5 cm were consecutively treated from 1997 to 2001 with neoadjuvant chemotherapy based on epirubicin 60 mg/m2/day on days 1 and 2 and ifosfamide 1.8 gr/m2/day on days 1 through 5 every three weeks. Evaluation of objective tumor response and toxicity were carried out according to WHO criteria. RESULTS: Nine partial responses were documented; stable disease in 11 patients, progressive disease in one patient. Apart from nine cases of grade 4 neutropenia, the treatment was generally well-tolerated. Twelve patients underwent conservative and limb salvage surgery. CONCLUSION: This therapeutic approach seems to be effective in facilitating surgery. Neutropenia was the most significant toxicity but it was preventable or medically treatable with G-CSF support.

[Histophenotypical variants of squamous cell carcinoma of the skin].

Cutaneous squamous cell carcinoma (SCC) is, in its most frequent presentation, a moderately aggressive neoplastic disease. It can, however, present in a moltitude of clinico-pathological variants, some of which are characterized by a more malignant attitude. It is important to determine which tumors, among the various histophenotypes, are high risk in order to establish the appropriate treatment and follow-up. Histologic subtype has been considered as a possible variable in determining the prognosis of cutaneous SCC. We report our experience with 3 cases of peculiar variants of cutaneous SCC.
