With recent advances in laparoscopy, specifically the development of laparoscopic splenectomy, a complete laparoscopic Hodgkin's staging procedure is now possible. Using five trocars and the patient in the right semidecubitus position, six laparoscopic staging procedures were performed. All were stages IIA or IIB pre-operatively, and none were upgraded to stage III or IV as a result of the procedure. Operative time was from 185-255 min. (mean 210 min.) There were no operative morbidities or mortalities associated with the procedure. We believe this procedure will be adopted by more surgeons as they become more comfortable in performing laparoscopic splenectomies.

OBJECTIVES: We report our initial experience using laparoscopic instruments and techniques in the performance of radical retropubic prostatectomy (RRP) through an entirely extraperitoneal endoscopic (EE) approach. METHODS: A 62-year-old man with a Gleason score of 7 and clinical stage T1c adenocarcinoma of the prostate underwent EERRP. The procedure was evaluated for achievement of removal of the prostate and seminal vesicles and for complete vesicourethral anastomosis. Operative time, blood loss, hospital stay, and pathologic findings were also evaluated. RESULTS: Complete endoscopic removal of the prostate and seminal vesicles was achieved. Endoscopic reconstruction of the bladder neck with a watertight anastomosis was successful. Operative time was 5 hours and 45 minutes, with an estimated blood loss of 600 cc. Hospital stay was 2.5 days. Final pathologic evaluation was a Gleason score of 7 and Stage T2 disease with negative margins. CONCLUSIONS: The initial experience for EERRP is encouraging. Further evaluation to refine the technique and determine its efficacy and role in treating prostate cancer is in order.

BACKGROUND: Large-core biopsies or open biopsies with needle localization have been the mainstay of treatment for evaluating nonpalpable mammographic abnormalities. The newly introduced Advanced Breast Biopsy Instrumentation (ABBI) system combines digital stereotactic imaging with a highly developed single-use biopsy device to locate and remove a radiographically discovered breast lesion to an accuracy of 1 mm. STUDY DESIGN: We conducted a review of the first 58 cases involving the use of the ABBI system. This article evaluates the accuracy of specimen targeting, the success rate of lesion removal, the operative complications, the mechanical difficulties, and patient satisfaction with the ABBI system. RESULTS: The lesion was removed successfully in 47 of the 58 cases. Nine patients were eliminated in initial screening and the procedure could not be completed in two. Although the success rate was high, 14 of the procedures required conversion to "open" ABBI procedures for completion of the biopsy. CONCLUSIONS: The ABBI system is an alternative to open biopsy with needle localization or large-core biopsy for nonpalpable mammographic abnormalities. This technique allows complete removal of the lesion in a one-step procedure. The ABBI system has certain limitations and mechanical problems, at least currently, and offers an advantage over current diagnostic modalities in a very limited number of cases only.

Open surgery in a severely anemic patient may be complicated by a substantial blood loss from a large incision and subsequent poor wound healing secondary to the anemia. We report our success in performing a splenectomy laparoscopically in a profoundly anemic patient. A 50-year-old white male Jehovah's Witness who was HIV positive was referred for splenectomy after he developed profound, worsening anemia secondary to hypersplenism that was refractory to medical management. His preoperative hemoglobin and hematocrit levels were 2.7 g/dl and 8.8%, respectively, but his religious beliefs precluded transfusion. A laparoscopic splenectomy by the posterior gastric approach was performed. The patient tolerated the surgery well and experienced no additional morbidity. On postoperative day 7, his hemoglobin and hematocrit were 6.8 g/dl and 22%, respectively. We conclude that laparoscopic splenectomy is an attractive procedure in a severely anemic patient who requires splenectomy and refuses blood transfusion.

The objective of this study was to determine whether extraperitoneal lymph node dissection for the staging of prostate cancer and extraperitoneal herniorrhaphy could be performed concomitantly with acceptable operative time and morbidity. Sixty patients underwent endoscopic extraperitoneal lymph node dissection (EEPLND) between 1991 and 1996. Eleven of these had 14 hernias repaired with polypropylene mesh. Endoscopic hernia repair added an average of 15 to 20 minutes to the EEPLND, resulting in an average operative time of 127 minutes (range 90 to 182 minutes). There was no difference in postoperative pain between patients undergoing combined operations and those undergoing EEPLND alone. The mean hospital stay after either procedure was 48 hours. There were no complications in the group undergoing herniorrhaphy. We conclude that extraperitoneal endoscopic hernia repair can be safely performed with EEPLND when necessary.

Resident competence in both open and laparoscopic cholecystectomy (LC) has been a concern among general surgeons. Laparoscopic surgery was late in coming at many surgical residency programs in the United States, and many residents have graduated with limited experience in LC. We are chief residents who were fortunate enough to start our training when LC was first introduced at our institution in 1990. This report summarizes our experience with LC in our chief year, during which we performed LC on 147 patients. The average operating time was 37 minutes (range, 12-82 minutes). Six patients (4%) required conversion to an open procedure. There were three complications (2 postoperative cystic duct leaks and 1 intraoperative common bile duct injury) for an overall complication rate of 2%. There was no mortality. It is our conclusion that graduating chief residents with 5 years' exposure to LC may perform the procedure with a complication rate comparable to that reported in the current literature. Insuring that graduating chief residents have adequate training in open cholecystectomy may become a more pressing issue in the near future.
