Decreasing length of stay in bariatric surgery: The power of suggestion.

OBJECTIVE: Enhanced recovery has been utilized to decrease length of stay and cost in bariatric surgery. We have recently focused efforts on pre-operative education with regards to discharge on the first post-operative day. The aim of this study was to determine the effectiveness of pre-operative education on discharge timing and readmission rates. METHODS: A retrospective review was conducted after revising discharge expectation education. Patients undergoing first time bariatric operations were included. Early group education focused on average patient stay of 2 postoperative days. Revised education informed patients they could go home on the first post-operative day. RESULTS: A total of 125 patients met inclusion criteria. Implementation of preoperative education was associated with a decrease in mean LOS and greater percentage of patients discharged on post-operative day one. There was no difference in readmission and complication rates. CONCLUSION: Effective pre-operative education can decrease length of stay in first time laparoscopic bariatric surgery.

Incidence and outcomes of ventral hernia repair after robotic retropubic prostatectomy: A retrospective cohort of 570 consecutive cases.

BACKGROUND: Robotic retropubic prostatectomy (RRP) has become one of the most commonly performed robotic procedures in the United States. Ventral hernia (VH) has been increasingly recognized as an important complication after laparoscopic procedures, in general. However, data related to VH after robotic procedures is relatively scarce, especially after RRP. With increasing popularity of RRP, the purpose of this study was to look at the incidence of VH and outcomes of ventral hernia repair (VHR) after RRP. METHODS: All patients who underwent RRP at a single institution between January 2012 and June 2014 were studied retrospectively using electronic medical records. RESULTS: A total of 570 patients underwent RRP, of which 33 (5.8%) developed VH during the study period. Fourteen (42%) patients were obese and five (15%) had diabetes. One patient (3%) had a surgical site infection after RRP and two (6%) patients were on immunomodulators/steroids. Median duration to develop VH after RRP was 12 (1-25) months. Out of the 33 patients with VH, ten (33%) underwent VHR; five laparoscopic and five open. Median size of hernia defect and mesh used was 25 (1-144) cm2 and 181 (15-285) cm2, respectively. Median length of hospital stay and follow up was 0 (0-4) days and 12 (1-14) months, respectively. One patient who had initial VHR done at an outside institution had a recurrence. Thirty-two (97%) patients were alive at their last follow up. One patient died secondary to progression of prostate cancer. There was no significant 30 day morbidity (surgical site infection, fascial dehiscence, pneumonia, acute kidney injury, myocardial infarction). Of patients who decided non-operative management of VH (n = 23, 67%), none developed a complication requiring emergent surgical intervention. CONCLUSION: The incidence of VH after RRP is likely underreported in prior studies. Repair, either laparoscopic or open, is safe and effective in experienced hands. Patients who decide on watchful waiting can be followed with minimal risk of incarceration/strangulation. Further studies are needed to analyze the extraction techniques after RRP and correlate with incidence of VH.

Incidence and impact of postoperative atrial fibrillation after minimally invasive esophagectomy.

Atrial fibrillation (AF) following open esophagectomy has been associated with increased rates of pulmonary and anastomotic complications, and mortality. This study seeks to evaluate effects of AF after minimally invasive esophagectomy (MIE). A retrospective review of patients consecutively treated with MIE for esophageal carcinoma, dysplasia. and benign disease from November 2006 to November 2011 was performed. One hundred twenty-one patients underwent MIE. Median age was 65 years (range 26-88) with 85% being male. Thirty-eight (31.4%) patients developed AF postoperatively. Of these 38 patients, 7 (18.4%) had known AF preoperatively. Patients with postoperative AF were significantly older than those without postoperative AF (68.7 vs. 62.8 years, P = 0.008) and more likely to be male (94.7% vs. 80.7%, P = 0.04). Neoadjuvant chemoradiation showed a trend toward increased risk of AF (73.7% vs 56.6%, P = 0.07). Sixty-day mortality was 2 of 38 (5.3%) in patients with AF and 4 of 83 (6.0%) in the no AF cohort (P = 1.00). The group with AF had increased length of hospitalization (13.4 days vs. 10.6 days P = 0.02). No significant differences in rates of pneumonia (31.6% vs. 21.7% P = 0.24), stricture (13.2% vs. 26.5% P = 0.10), or leak requiring return to operating room (13.2% vs. 8.4% P = 0.51) were noted between groups. We did not find an increased rate of AF in our MIE cohort compared with prior reported rates in open esophagectomy populations. AF did result in an increased length of stay but was not a predictor of other short-term morbidities including anastomotic leak, pulmonary complications, stenosis, or 60-day mortality.

The difficult gall bladder: Outcomes following laparoscopic cholecystectomy and the need for open conversion.

INTRODUCTION: Surgery for the difficult gallbladder (DGB) is associated with increased risk compared to more routine laparoscopic cholecystectomies (LC). Laparoscopic "damage control" methods including cholecystostomy, fundus-down approach and subtotal cholecystectomy (SC) have been proposed to avoid conversion to open. We hypothesized that a Total LC (TLC) for DBG can be completed safely with an acceptably low conversion rate. MATERIAL AND METHODS: All patients that underwent LC from January 2005-June 2015 were retrospectively reviewed. Cases met criteria for DGB if they were necrotic/gangrenous, involved Mirizzi syndrome, had extensive adhesions, were converted to open, lasted more than 120 min, had prior tube cholecystostomy or known GB perforation. RESULTS: A total of 2212 patients underwent LC during the study time period, of which 351 (15.8%) met criteria for DGB. Of these cases, 213 (60.7%) were admitted from the emergency department and 67 (19.1%) underwent urgent/emergent cholecystectomy (within 24 h). Additionally 18 (5.1%) had pre-operative tube cholecystostomies. Seventy patients (19.9%) were converted to open. Indications for conversion included severe inflammation/adhesion (n = 31, 46.3%), difficult anatomy (n = 14, 20.9%) and bleeding (n = 6, 9.0%). Predictors for conversion included urgent/emergent intervention (OR, 0.80; 95% CI 0.351-0.881, p = 0.032), previous abdominal surgery (OR, 2.18; 95% CI, 1.181-4.035, p = 0.013) and necrotic/gangrenous cholecystitis (OR, 1.92; 95% CI, 1.356-4.044, p = 0.033). Comparing the TLC and the conversion groups, mean operative time and length of hospital stay were significantly different; 147 ± 47 min vs 185 ± 71 min; p < 0.005 and 3 ± 2 days vs 5 ± 3 days; p = 0.011, respectively. There was no significant difference in postoperative hemorrhage, subhepatic collection, cystic duct leak, wound infection, reoperation and 30 day mortality. There was no bile duct injury in either group. CONCLUSION: Total laparoscopic cholecystectomy can be safely performed in difficult gallbladder situations with a lower conversion rate than previously reported. Possible predictors of conversion include urgency, necrotic gallbladder and history of prior abdominal surgeries. For patients converted to open, similar morbidity and mortality can be expected.

Challenging a surgical dictum: results from a 10-year experience on the safety of open inguinal herniorrhaphy in patients on chronic warfarin therapy.

BACKGROUND: Previous reports document the safety of open inguinal herniorrhaphy in patients on chronic warfarin therapy; however, the practice remains controversial. This study is a 10-year update of our experience. METHODS: A retrospective review of 1,839 consecutive patients undergoing open inguinal hernia repair was conducted from 2000 to 2010. All patients on chronic warfarin therapy were included. Three groups: continuation (CW), discontinuation (DW) and case-matched control (C) not on warfarin therapy were compared for operative details and postoperative complications. RESULTS: One hundred and fifty-eight patients were on chronic warfarin therapy. Of these, 40 patients (25%) continued on warfarin during the perioperative period (CW). Average preoperative international normalized ratio (INR) was 2.15 ± 0.76 for CW and 1.38 ± 0.42 for DW, p < 0.001. Mean operative times were equivalent between all three groups (88 min CW vs. 85 min DW vs. 79 min C, p = 0.518). Although CW patients experienced higher incidences of both hematoma and urinary retention overall, no statistically significant differences in complication rates were seen between the three groups (hematoma = 10 vs. 8% DW vs. 5% C, p = 0.703; urinary retention = 15 vs. 10% DW vs. 8% C, p = 0.541). Comparing patients by INR, there were no statistically different postoperative complication rates, particularly for hematoma (8% INR <2 vs. 9.5% INR = 2-3 vs. 20% INR >3, p = 0.65). CONCLUSION: Maintenance of warfarin therapy during the perioperative period for open inguinal herniorrhaphy results in equivalent operative times and postoperative complications as discontinuation.

Inguinal hernia repair in women: is the laparoscopic approach superior?

PURPOSE: Laparoscopic inguinal hernia repair is associated with reduced post-operative pain and earlier return to work in men. However, the role of laparoscopic hernia repair in women is not well reported. The aim of this study was to review the outcomes of the laparoscopic versus open repair of inguinal hernias in women and to discuss patients' considerations when choosing the approach. METHODS: A retrospective chart review of all consecutive patients undergoing inguinal hernia repair from January 2005 to December 2009 at a single institution was conducted. Presentation characteristics and outcome measures including recurrence rates, post-operative pain and complications were compared in women undergoing laparoscopic versus open hernia repair. RESULTS: A total of 1,133 patients had an inguinal herniorrhaphy. Of these, 101 patients were female (9 %), with a total of 111 hernias. A laparoscopic approach was chosen in 44 % of patients. The majority of women (56 %) presented with groin pain as the primary symptom. Neither the mode of presentation nor the presenting symptoms significantly influenced the surgical approach. There were no statistically significant differences in hernia recurrence, post-operative neuralgia, seroma/hematoma formation or urinary retention between the two approaches (p < 0.05). A greater proportion of patients with bilateral hernias had a laparoscopic approach rather than an open technique (12 vs. 2 %, p = 0.042). CONCLUSIONS: Laparoscopic herniorrhaphy is as safe and efficacious as open repair in women, and should be considered when the diagnosis is in question, for management of bilateral hernias or when concomitant abdominal pathology is being addressed.

Bone anchor mesh fixation for complex laparoscopic ventral hernia repair.

BACKGROUND: Laparoscopic ventral hernia repair (LVHR) has gained wide acceptance by both surgeons and patients, but hernias that approach a bony prominence are more complex due to the difficulty of proper fixation. This study was conducted to evaluate the use of bone anchor mesh fixation for complex LVHR. METHODS: A prospective study of patients having complex LVHR with bone anchors was conducted using patients from 2 academic institutions between July 2003 and December 2007. Patient demographic data, characteristics of the hernia, operative details, and postoperative outcomes were recorded. RESULTS: A total of 30 patients who had LVHR using bone anchors were evaluated (20 women, 10 men; mean age 60.9 years, range 41-83 years). In all, 17 suprapubic and 13 lateral hernias were included, requiring a mean of 2.8 and 3.2 bone anchors, respectively. The average hernia defect was 263 cm(2) (range 35-690 cm(2)), and the average mesh size was 663 cm(2) (range 255-1360 cm(2)). Mean operative time was 218 minutes (range 98-420 minutes), with an estimated blood loss of 46 mL (range 10-100 mL). The average length of stay was 5.2 days (range 1-26 days). Seven patients (23.3%) developed postoperative complications, and 1 patient in this study died (mortality 3.3%). During follow-up of 13.2 months (range 1-26 months), 2 patients (6.7%) developed a recurrent hernia. CONCLUSIONS: Bone anchors can be used successfully in the laparoscopic repair of complex ventral hernias, particularly with suprapubic and lateral hernias that approach a bony prominence. The complication rate is acceptable, with a short hospital stay and low recurrence rate.

Laparoscopic parastomal hernia repair.

BACKGROUND: Management of the parastomal hernia represents a common clinical dilemma for both the surgeon and patient. Once established, these defects are notoriously difficult to treat. Although most parastomal hernias can be managed nonoperatively, approximately 30% will require intervention secondary to complications such as obstruction, pain, bleeding, poorly fitting appliances, or leakage. Overall complication rates of up to 88%, combined with a growing body of literature citing decreased patient morbidity and improved outcomes with laparoscopic tension-free mesh repair of ventral hernias, have led many surgeons to apply these techniques to this difficult problem. METHODS: This was a retrospective review of 21 consecutive patients who underwent laparoscopic repair of their parastomal hernias with ePTFE mesh. RESULTS: Nine (43%) were ileal conduits, seven (33%) were ileostomies, and five (24%) were colostomies. Eight patients had undergone prior hernia repair. Follow-up ranges from 1 to 36 months (average 14 months). There has been one recurrence (5%). Other complications included laparoscopic re-operation for obstruction of a urinary conduit (n=1), mesh removal for infection (n=2), Clostridium Difficile colitis (n=1), pneumonia (n=2), renal failure (n=1), surgical site infection (n=1), and bowel obstruction at a site remote from the hernia repair (n=2). CONCLUSION: The laparoscopic approach to parastomal hernias is a new technique that offers many potential advantages over conventional open repairs. Based on our initial experience, this repair seems to be associated with a low recurrence rate.

Plastic wound protectors do not affect wound infection rates following laparoscopic-assisted colectomy.

BACKGROUND: Wound protectors are plastic sheaths that can be used to line a wound during surgery. Wound protectors can facilitate retraction of an incision without the need for other mechanical retractors and have been proposed as deterrents to wound infection. The purpose of this study was to define the ability of wound protectors to reduce the rate of infection when used in laparoscopic-assisted colectomy. METHODS: We completed a retrospective review of the medical records of patients undergoing nonemergent laparoscopic-assisted colectomy between February 1999 and November 2002. All completely laparoscopic cases were excluded. The wound protector, when used, was applied to the extraction incision during the externalized portion of the procedure (colon and mesentery transection, anastomosis). Outcomes for patients with and without the use of a wound protector were compared. RESULTS: A total of 141 patients underwent laparoscopic-assisted colectomy (98 for benign/malignant tumors, 35 for diverticular disease, and eight for Crohn's disease). There were no differences between the wound protector group ( n = 84) and the no wound protector group ( n = 57) with respect to mean age (55 vs 58 years), average body mass index (27 vs 29 kg/m2), gender, indication for surgery, comorbidities, antibiotics used, or mean operative time (185 vs 173 min). Nine patients in the wound protector group and eight in the no wound protector group developed a wound infection at the colon extraction site ( p = 0.42). Patients undergoing resection for Crohn's disease or diverticulitis had a higher infection rate (18.6%) than patients undergoing resection for polyps or cancer (9.2%; p < 0.05). No wound recurrence of cancer was observed in either group at a mean follow-up of 23 months (range, 3-48). CONCLUSIONS: The wound protector, although useful for mechanical retraction of small wounds, does not significantly diminish the rate of wound infection at the bowel resection/anastomotic site. Patients undergoing elective resection for inflammatory processes have higher infection rates than patients undergoing laparoscopic-assisted colectomy for polyps or cancer.

Comparison of ultrasonic energy, bipolar thermal energy, and vascular clips for the hemostasis of small-, medium-, and large-sized arteries.

BACKGROUND: Advanced laparoscopic procedures have necessitated the development of new technology for vascular control. Suture ligation can be time-consuming and cumbersome during laparoscopic dissection. Titanium clips have been used for hemostasis, and recently plastic clips and energy sources such as ultrasonic coagulating shears and bipolar thermal energy devices have become popular. The purpose of this study was to compare the bursting pressure of arteries sealed with ultrasonic coagulating shears (UCS), electrothermal bipolar vessel sealer (EBVS), titanium laparoscopic clips (LCs), and plastic laparoscopic clips (PCs). In addition, the spread of thermal injury from the UCS and the EBVS was compared. METHODS: Arteries in three size groups (2-3, 4-5 and 6-7 mm) were harvested from freshly euthanized pigs. Each of the four devices was used to seal 16 specimens from each size group for burst testing. A 5-Fr catheter was placed into the open end of the specimen and secured with a purse-string suture. The catheter was connected to a pressure monitor and saline was infused until there was leakage from the sealed end. This defined the bursting pressure in mmHg. The ultrasonic shears and bipolar thermal device were used to seal an additional 8 vessels in each size group, which were sent for histologic examination. These were examined with hematoxylin and eosin stains, and the extent of thermal injury, defined by coagulation necrosis, was measured in millimeters. Analysis of variance was performed and, where appropriate, a Tukey's test was also performed. RESULTS: The EBVS's mean burst pressure was statistically higher than that of the UCS at 4 or 5 mm (601 vs 205 mmHg) and 6 or 7 mm (442 vs 175 mmHg). EBVS had higher burst pressures for the 4 or 5-mm group (601 mmHg) and 6 or 7-mm group (442 mmHg) compared with its pressure at 2 or 3 mm (128 mmHg) ( p = 0.0001). The burst pressures of the UCS and EBVS at 2 or 3 mm were not significantly different. Both clips were statistically stronger than the thermal devices except at 4 or 5 mm, in which case the EBVS was as strong as the LC (601 vs 593 mmHg). The PC and LC were similar except at 4 or 5 mm, where the PC was superior (854 vs 593 mmHg). The PC burst pressure for 4 or 5 mm (854 mmHg) was statistically higher than that for vessels 2 or 3 mm (737 mmHg) but not different from the 6 or 7 mm pressure (767 mmHg). Thermal spread was not statistically different when comparing EBVS and UCS at any size (EBVS mean = 2.57 mm vs UCS mean = 2.18 mm). CONCLUSIONS: Both the PC and LC secured all vessel sizes to well above physiologic levels. The EBVS can be used confidently in vessels up to 7 mm. There is no difference in the thermal spread of the LigaSure vessel sealer and the UCS.

Laparoscopic repair of traumatic diaphragmatic injuries.

BACKGROUND: The purpose of this study was to evaluate the feasibility and limitations of laparoscopic repair of traumatic diaphragmatic injuries. METHODS: Laparoscopic repair of an acute traumatic diaphragmatic laceration or chronic traumatic diaphragmatic hernia was attempted in 17 patients between January 1997 and January 2001. The patients in the study included 13 men and 4 women with a mean age of 33.2 years (range, 15-63 years). Nine patients had a blunt injury, and eight patients had a penetrating injury. Laparoscopic repair was attempted for eight patients during their hospitalization for the traumatic injury (mean, 2.3 days; range, 0-6 days) and for ten patients with a chronic diaphragmatic hernia (mean, 89 months; range, 5-420 months). The chronic diaphragmatic hernias-presented with abdominal pain (9/9), or vomiting (3/9). RESULTS: Thirteen traumatic diaphragmatic injuries were repaired laparoscopically, and four (2 acute and 2 chronic) required conversion. Among the laparoscopically repaired diaphragmatic injuries, three defects (chronic) were repaired using expanded polytetrafluoroethylene (ePTFE), and nine were repaired primarily. The mean length of the diaphragmatic defects was 4.6 cm (range, 1.5-12 cm). The mean operative time was 134.7 min (range, 55-200 min). The mean estimated blood loss was 108.5 ml (range, 30-500 ml), and the postoperative length of stay was 4.4 days (range, 1-12 days). There were no intraoperative complications, but three patients developed pulmonary complications (atelectasis/pneumonia). Follow-up evaluation was available for 11 patients. There were no documented recurrences after a mean follow-up period of 7.9 months (range, 1 week to 24 months). Conversion resulted from a reluctance or inability to perform laparoscopic suture of transverse diaphragmatic lacerations longer than 10 cm anterior to the esophageal hiatus and adjacent to the pericardium (n = 2) or communicating with the esophageal hiatus (n = 2). One patient also required spleneotomy for an unrecognized splenic laceration that had occurred at the time of the original trauma. The four patients undergoing laparotomy had a mean postoperative discharge date of 8.7 days (range, 6-14 days). CONCLUSIONS: Laparoscopy is an alternative approach to repairing acute traumatic diaphragmatic lacerations and chronic traumatic diaphragmatic hernias. Large traumatic diaphragmatic injuries adjacent to or including the esophageal hiatus are best approached via laparotomy.

Outcomes for laparoscopic bilateral adrenalectomy.

BACKGROUND AND PURPOSE: Laparoscopic adrenalectomy has become the preferred surgical approach to manage adrenal disorders. Bilateral adrenalectomy is performed for diseases that are unresponsive to medical management and, frequently, for neoplastic disease. The aim of this study was to review our experience with laparoscopic bilateral adrenalectomy and to evaluate its safety, efficacy, and outcomes. PATIENTS AND METHODS: Between July 1996 and May 2001, five male and two female patients with a mean age of 46 years (range 15-69 years) presented for bilateral adrenalectomy (pheochromocytoma [N = 3], Cushing's disease [N = 3], and metastatic cancer [N = 1]). All procedures were performed using a lateral transperitoneal approach. One gland was excised, the patient was repositioned to the opposite lateral decubitus position, and the remaining gland was removed. RESULTS: Laparoscopic bilateral adrenalectomy was completed in all seven patients. The mean tumor/gland size on the right was 5.0 cm (range 3.1-7.0 cm) and on the left was 5.6 cm (range 3.6-7.0 cm). The mean operative time was 308 minutes (range 190-430 minutes), and the mean estimated blood loss was 138 mL (range 30-300 mL). One patient with a pheochromocytoma experienced intraoperative hypertension necessitating treatment. There were no postoperative complications. The mean postoperative hospital stay was 5.1 days (range 3-9 days). All patients have been treated postoperatively with daily hydrocortisone and fludrocortisone replacement. After a mean follow-up of 33 months (range 2-45 months), six patients are alive. The patient undergoing bilateral adrenalectomy for metastatic lung cancer died from recurrent disease 13 months after resection. CONCLUSION: Laparoscopic bilateral adrenalectomy is safe and effective. Patients are discharged postoperatively in a relatively short time with few complications. Appropriate steroid replacement and close follow-up allows these patients to return to self-reliance.

Prospective randomized evaluation of surgical resident proficiency with laparoscopic suturing after course instruction.

BACKGROUND: Laparoscopic suturing is required to develop competency in advanced laparoscopy. METHODS: Manuals detailing laparoscopic suturing were give to 17 Surgery residents. One week later they performed a suture on a training model. Time (s), accuracy (mm), and knot strength (lb) were recorded. The residents were blindly randomized to intervention (n = 9) and control (n = 8) groups. The intervention residents attended a 60-min course with lecture, video, and individual proctoring. Two weeks later they performed a stitch with standard laparoscopic instruments and a stitch with a suturing assist device. Statistical analysis included a Wilcoxon rank-sum test. RESULTS: The intervention residents decreased their suturing time from the first to the second stitich (732.4-257.6s), the control and residents decreased their time from 500.2 s to 421.8 s. The time required to perform the second stitch showed no significant difference between the two groups (p = 0.46), but the difference in reduced time between the first and second stitch was significant (p = 0.001). Using the suturing assist device for the third suture, the intervention and control groups both decreased their times significantly. The control residents performed almost as quickly as the intervention residents with the suturing; device (p = 0.11). Accuracy and knot strength were not different in any test. CONCLUSIONS: Residents can improve suturing skill with a short didactic course and individual proctoring. A suturing assist device decreases time required by inexperienced surgeons to device perform an intracorporeal tie.

Minilaparoscopic appendectomy.

The purpose of this study was to evaluate the feasibility of using 2-mm laparoscopic instruments in the treatment of appendicitis and to identify risk factors that may limit their use. Minilaparoscopic appendectomy was performed through a 2-mm port in the umbilicus for a videoendoscope, a 2-mm working port in the right upper quadrant, and a 5/12-mm suprapubic port for an endoscopic stapler. Minilaparoscopic appendectomy was attempted in 26 consecutive patients with appendicitis. Thirty-two consecutive patients undergoing conventional laparoscopic appendectomy with 5- and 10-mm instruments and videoendoscopes before the availability of 2-mm instrumentation were analyzed for comparison. Statistical comparisons were made by the Student t test and Fisher exact test. Differences were considered statistically significant at a P value less than 0.05. There were no conversions to an open appendectomy in the minilaparoscopic appendectomy or conventional laparoscopic appendectomy group. The mean operative time was 69.5 minutes for the minilaparoscopic appendectomy group and 85.5 minutes for the conventional laparoscopic appendectomy group (P = 0.02). The mean postoperative length of stay was 1.7 days for the minilaparoscopic appendectomy group and 2.5 days for the conventional laparoscopic appendectomy group (P = 0.08). There was no significant difference in the complication rates (P = 0.31). Minilaparoscopic appendectomy was completed in 13 (50.0%) patients. Independent risk factors (P = 0.05) for conversion to 5- or 10-mm ports were a retrocecal appendix and increasing patient age. There were no differences in the mean postoperative length of stay (P = 0.12) or complication rate (P = 0.39) between the two groups, but mean operative time was longer (P = 0.05) in the converted group. Perioperative outcomes for minilaparoscopic appendectomy are comparable to those of conventional laparoscopic appendectomy. The use of 2-mm instrumentation in the management of appendicitis is limited in patients with retrocecal appendicitis. Increasing patient age and a history of abdominal surgery may influence the need to convert 2-mm ports to 5- or 10-mm ports.

Long-term results of laparoscopic splenectomy for immune thrombocytopenic purpura.

OBJECTIVE: To assess the results of laparoscopic splenectomy as a treatment for immune thrombocytopenic purpura (ITP). MATERIAL AND METHODS: We conducted a retrospective study of all patients who underwent laparoscopic splenectomy for ITP at our institution between August 1992 and May 1997. RESULTS: Of 27 patients who underwent attempted laparoscopic splenectomy for ITP at our institution during the study period, 26 had completion of the procedure without conversion to an open splenectomy. The median postoperative hospital stay was 1.5 days, and no postoperative deaths occurred. In one patient, pancreatitis developed postoperatively. In four patients, splenectomy failed--two initially and two subsequently--and reinstitution of medical therapy was necessary. The other patients have remained free of medication, and 19 patients have platelet counts greater than 100 x 10(9)/L. The 3-year actuarial success rate was 81.5%. Response to corticosteroid therapy preoperatively may be an indicator of success of splenectomy. CONCLUSION: Laparoscopic splenectomy is safe and allows prompt recovery. Long-term response rates are similar to those achieved with open splenectomy.
