Management of hyperparathyroidism in an endemic goiter area.

In an endemic goiter area patients with hyperparathyroidism (HPTH) frequently also have thyroid abnormalities. In a retrospective study of 95 patients with HPTH we assessed the diagnostic accuracy of imaging techniques (ultrasonography or radionuclide scanning) for preoperative localization of parathyroid adenomas. Altogether 86% of our patients had goiter, requiring thyroid resections in 37%. For 19 patients the parathyroid exploration was the second or third cervical operation, most of them due to goiter. We found that the overall rate of transient and permanent recurrent nerve paralysis is considerably increased in patients with previous neck surgery (26% vs. 7%). The combination of ultrasonography and radionuclide scanning can lead surgeons to the site of parathyroid lesions responsible for HPTH in 85% of cases, although frequent nodular goiters can produce pitfalls for correct imaging in iodine-deficient countries. In endemic goiter areas preoperative localization studies can be recommended in patients with primary HPTH--for evaluation of thyroid pathology possibly leading to resection or its accuracy in localizing parathyroid adenomas. These studies also seem justified in patients with previously unsuccessful neck explorations for HPTH.

Laparoscopic appendectomy does not change the incidence of postoperative infectious complications.

BACKGROUND: It is not clear whether the laparoscopic approach does decrease the incidence of postoperative infectious complications after appendectomy. METHODS: One hundred sixty-nine patients were randomized, 87 with laparoscopic (LA) and 82 with open appendectomy (OA). Patients in the OA group had a McBurney incision; LA was performed in the lithotomy position. RESULTS: Acute appendicitis was confirmed in 75% of patients. The appendix was perforated in 5 patients of the LA versus 2 patients of the OA group. No conversion to the open procedure was necessary. The median operating time was 35 minutes in the LA group and 31 minutes in the open group (P = 0.58). The median postoperative hospital stay was shorter after laparoscopic than after open surgery (3 days versus 4 days, P = 0.026), whereas the time required for return to work was not significantly different (14 versus 15 days). There were 5 (6%) patients with superficial wound infection following LA and 6 (7%) after OA (P = 0.67). Intra-abdominal fluid collections were found in 2 (2%) patients following LA and 3 (4%) patients following OA (P = 0.60). In the LA group, 3 patients presented with intra-abdominal hemorrhage and another 3 developed a paralytic ileus that was treated conservatively. CONCLUSIONS: Laparoscopic appendectomy is as safe and as effective as the open procedure; however, it does not decrease the rate of postoperative infectious complications.

Respiratory symptoms in patients with gastroesophageal reflux disease following medical therapy and following antireflux surgery.

BACKGROUND: It is not known whether antireflux surgery is more effective than medical therapy to control respiratory symptoms (RS) in gastroesophageal reflux disease (GERD). METHODS: In 21 GERD patients with RS, reflux was assessed by endoscopy, manometry, and pH monitoring. Patients had proton pump inhibitor therapy and cisapride for 6 months. After GERD relapsed following withdrawal of medical therapy, 7 patients with normal esophageal peristalsis had a laparoscopic Nissen fundoplication and 14 with impaired peristalsis a Toupet fundoplication. Respiratory symptoms were scored prior to treatment, at 6 months following medical therapy, and at 6 months after surgery. RESULTS: Heartburn and esophagitis were effectively treated by medical and surgical therapy. Only surgery improved regurgitation. Respiratory symptoms improved in 18 patients (85.7%) following surgery and in only 3 patients (14.3%) following medical therapy (P <0.05). Esophageal peristalsis improved following the Toupet fundoplication. CONCLUSION: Medical therapy fails to control reflux since it does not inhibit regurgitation. Surgery controls reflux and improves esophageal peristalsis, which contributes to its superiority over medical therapy in the treatment of RS associated with GERD.

Pain treatment after thoracotomy: is it a special problem?

BACKGROUND: Although it is frequently stated in the literature that thoracotomy is one of the most painful operative incisions, few data supporting this view are available. METHODS: Patients' postoperative pain experience can be assessed on the basis of their usage of patient-controlled analgesia. In a prospective trial the daily self-administered doses of analgesics in 55 patients within the first 4 days after posterolateral thoractomy were compared with those in 30 patients for the same number of days after median laparotomy. The visual analog scale was used as a second measure to evaluate postoperative pain. RESULTS: On the basis of patient-controlled analgesia usage on the first postoperative day and the visual analog scale score for the first 2 days, a small but significant difference between the two patient groups was found which showed that thoracotomy is less painful than median laparotomy. CONCLUSIONS: The common belief that posterolateral thoracotomy is a very painful operative access is not true. Therefore it is not necessary to use special techniques for postthoracotomy pain relief in these patients. Patient-controlled analgesia is sufficient for pain relief after major thoracic or abdominal incisions.

[Laparoscopic versus conventional appendectomy: a prospective randomized study].

The discussion about laparoscopic appendectomy has increased since the introduction of this method. Randomized comparisons are still feasible, whereas this cannot be stated for other laparoscopic procedures (e.g., laparoscopic cholecystectomy). This randomized controlled trial included 170 patients. Open appendectomy was employed in 83 patients, and 87 were treated laparoscopically. The treatment groups were comparable regarding age, sex, Broca index, ASA classification, preliminary operations, and preoperative leucocytes. No statistically significant differences could be found with respect to surgical and general complications, operating time, consumption of analgesics and antibiotics, and return to work. The analysis revealed a statistically significant shorter hospital stay, a shorter time until return to normal physical activity, and a shorter duration of complaints for the laparoscopic group. We were unable to demonstrate any statistically significant advantage in using the open procedure.

Is there a role for laparoscopic ultrasonography (LUS)?

Laparoscopic ultrasound (LUS) was performed in 24 patients undergoing routine laparoscopic cholecystectomy at the Second Surgical Department of the University Hospital of Innsbruck, Austria. After introduction of the ultrasonic probe via the umbilical incision, liver, biliary tract, pancreas, kidneys, stomach, and colon were investigated to assess the sonomorphology of these organs and to judge whether or not LUS is a feasible and reliable means for screening the abdominal organs during routine surgery or laparoscopic staging of upper gastrointestinal (GI) tumors. In all cases, a very accurate investigation of these organs was possible, and the laparoscopic procedure was prolonged for only 15 to 20 min. In eight further patients, LUS was performed to investigate pancreatic pathology (six cases), stomach cancer (one patient), and primary hepatocellular carcinoma (one patient). Three additional patients (pancreatic lesions) who underwent intraoperative ultrasonography with the LUS probe were excluded from this evaluation.

Survival after surgical treatment of recurrent carcinoma of the rectum.

BACKGROUND: From January 1983 to January 1991, radical surgical treatment for carcinoma of the rectum was performed upon 154 patients in our department. In 30 instances, local treatment failure occurred and patients were treated either conservatively or operatively. Survival times of these 30 patients were compared to evaluate if operation, even in instances in which only palliative resection is possible, can prolong survival and if early diagnosis of recurrence leads to a higher rate of radical resections and subsequent cure. STUDY DESIGN: Patients were divided into three groups. Group 1 consisted of patients not undergoing an operation, patients in group 2 had a palliative resection and patients in group 3 had radical resections. The median survival time was estimated for each group. RESULTS: The median survival period was six months for group 1, 17 months for group 2, and 35.5 months for group 3. Four patients who underwent reoperation for cure are still alive: one with recurrent tumor after 28 months, and three without evidence of disease after 32, 42 and 43 months. The most valuable diagnostic mean in the detection of local recurrence was endosonography. CONCLUSIONS: Surgical treatment for recurrent carcinoma of the rectum is justified not only in cases having radical resection but also as a palliative approach. Compared to other investigative methods, endosonography seems to detect recurrences earlier, at a time when curative retreatment is still possible.
