Acalculous cholecystitis: the use of diagnostic laparoscopy.

Acalculous cholecystitis (AC) carries a high mortality in the critically ill patient. This is partly due to the delay in its diagnosis. Clinical diagnostic examinations are often misleading. The purpose of our study was to evaluate the use of laparoscopy as a diagnostic tool in the evaluation of the critically ill patient suspected of having AC. From May 1993 to January 1994, we evaluated 10 critically ill patients. Mean age was 56 years (range 17-90 years). Nine of the patients were trauma victims (8 blunt, 1 penetrating). The other patient was postcoronary bypass surgery. The laparoscopy was done after a mean of 15 days (range 6-54 days) after ICU admission. All patients were receiving ventilatory support, and all patients had elevated temperatures of greater than 38.5 degrees C. Five patients had abdominal tenderness, and 6 had elevated liver function tests (LFT). Six laparoscopies were done under local anesthesia and IV sedation at the bedside, and 4 were done in the operating room. All patients tolerated the procedure well with no complications. The laparoscopic findings were gangrenous cholecystitis in 2 patients. They both underwent laparoscopic cholecystectomies in the operating room. We elected to drain a very distended gallbladder in 1 patient, who eventually was found to have an empyema of the chest. The other 7 examinations were normal. Six of these patients recovered and were discharged. Our results suggest that laparoscopy can be used in the diagnosis of acalculous cholecystitis. Its positive and negative findings are valuable in the treatment of the critically ill. It can be done safely at the bedside.

Open versus laparoscopic appendectomy. A prospective randomized comparison.

OBJECTIVE: The authors compare open and laparoscopic appendectomy in a randomized fashion with regard to length of operation, complications, hospital stay, and recovery time. METHODS: Adult patients (older than 14 years of age) with the diagnosis of acute appendicitis were randomized to either open or laparoscopic appendectomy over a 9-month period. All patients received preoperative antibiotics. The operative time was calculated as beginning with the incision and ending when the wound was fully closed. Patients that were converted from laparoscopic to open appendectomy were considered a separate group. Return to normal activity and work were determined by questioning during postoperative clinic, telephone, or mailed questionnaire. RESULTS: There was a total of 169 patients randomized, 88 to the open and 81 to the laparoscopic group. The groups were similar demographically. Of the 81 laparoscopic patients, 13 (16%) were converted to open. In the open group, 70 patients (79.5%) had acute appendicitis and 21 (23.9%) had perforative appendicitis. In the laparoscopic group, 62 patients (76.5%) had acute appendicitis and 10 (12.3%) had perforative appendicitis. There was no statistical difference in the return to activity or work between the laparoscopic and open groups. The operative time was significantly longer in the laparoscopic group (102.2 minutes vs. 81.7 minutes, p < 0.01). The hospital stay of 2.2 days in the laparoscopic group and 4.3 days in the open group was statistically (p = 0.007). There was no difference in the hospital stay for those with acute appendicitis (1.89 days vs. 2.61 days, p = 0.067) compared with those with a normal appendix but with pelvic inflammatory disease (1.1 days vs. 2.3 days, p = 0.11). There was a significant difference in patients with perforative appendicitis (1.5 days vs. 9.5 days, p < 0.01). The hospital cost for patients having laparoscopic appendectomy was $6077 and for an open appendectomy $7227 (p = 0.164). There were no increased complications associated with the laparoscopic technique. CONCLUSION: Laparoscopic appendectomy is comparable to open appendectomy with regard to complications, hospital stay, cost, return to activity, and return to work. There was a greater operative time involved with the laparoscopic technique. Laparoscopic appendectomy does not offer any significant benefit over the open approach for the routine patient with appendicitis.

Negative laparotomy in abdominal gunshot wounds: potential impact of laparoscopy.

OBJECTIVE: To evaluate the morbidity and hospital stay resultant from negative exploratory laparotomy (NL) for abdominal gunshot wounds (ABGSWs) and the potential impact the use of diagnostic laparoscopy (DL) could have on these variables. DESIGN: A retrospective study was conducted. MATERIALS AND METHODS: The charts of all patients with ABGSWs over a 4-year period were reviewed. Data was collected on injuries, rate of NL, morbidity and hospital stay. This was compared to a subsequent group of patients with ABGSWs managed with a DL protocol. MEASUREMENTS AND MAIN RESULTS: Over a 4-year period, 817 patients had exploratory laparotomy (EL) for ABGSWs. The NL rate was 12.4% (101 of 817); 69 of these patients had no associated injury or other procedures. They had a 22% morbidity and an average hospital stay of 5.1 days. Subsequently, 85 patients with ABGSWs underwent DL. This group was similar to the EL group and would have undergone EL prior to the introduction of DL at our institution. In this group, 34 patients had no associated injury or other procedures. They had a 3% morbidity, and their average hospital stay was 1.4 days. The morbidity and hospital stay were statistically significantly reduced (p < 0.01) in patients with negative DL versus NL. CONCLUSIONS: These data demonstrate that NL is associated with a high morbidity and long hospital stay. The use of DL can reduce the rate of NL, and result in lower morbidity and shorter hospital stay in patients with ABGSWs.

Laparoscopy in 121 consecutive patients with abdominal gunshot wounds.

OBJECTIVE: The purpose of this study was to evaluate the sensitivity, specificity, and predictive value of diagnostic laparoscopy (DL) in a large group of stable patients with abdominal gunshot wounds (ABGSWs). DESIGN: This study was a prospective case series developed by management protocol. MATERIALS AND METHODS: In a 2 1/2-year period, DL was performed in 121 consecutive patients who were hemodynamically stable with ABGSWs and met protocol criteria. This represented 18% of all patients with ABGSWs seen in this period at the Ryder Trauma Center. The evaluation was conducted to determine peritoneal violation, the presence of intra-abdominal blood, and the need for exploration. MEASUREMENTS AND MAIN RESULTS: There were 42 (35%) positive and 79 (65%) negative DLs. In patients with positive DL, 39 (92.8%) had exploratory laparotomy. In this group, 32 (82%) had therapeutic laparotomy, 6 (15.4%) had nontherapeutic laparotomy, and 1 (2.5%) had a negative laparotomy. In this patient, DL was felt to be inadequate by the attending surgeon, although no penetration or intraperitoneal blood were present, and a negative laparotomy was done. This represents a failure rate of 0.8%. There were 3 (7.2%) positive DLs, in whom laparotomy was not performed. These patients had isolated nonbleeding liver injuries, and nontherapeutic laparotomy was successfully avoided. The negative DL group was divided into 47 patients (60%) with isolated ABGSWs, and 32 patients (40%) with associated injuries, mostly orthopedic and thoracic. There were no false-negative DLs and no delayed laparotomies in these 121 patients. There was no mortality in this study group. The sensitivity for peritoneal penetration was 100%, and the specificity was 98.7%. The positive predictive value was 97.6%, and the negative predictive value was 100%. In deciding on need for laparotomy (i.e., injury requiring repair), DL had a positive predictive value of 82%; more importantly, the negative predictive value was 100%. CONCLUSIONS: In stable patients with ABGSWs and questionable intra-abdominal injury, DL can be safely used. It is highly sensitive and specific. It can effectively reduce the incidence of negative and nontherapeutic laparotomies, and the overall morbidity and hospital stay in this group of patients.

Reclosure of the open abdomen.

BACKGROUND: The open abdomen technique for the treatment of diffuse peritonitis has gained acceptance. Our approach has been to use the zipper technique with daily irrigations. Once the abdominal problem has resolved, the mesh and zipper are removed. Surgeons are reluctant to reoperate on patients with such prior treatment because of the anticipation of a hostile abdomen. Our study is a retrospective review of 12 patients who were treated with the open abdomen technique. At a later date, they underwent elective reoperation. STUDY DESIGN: The charts of 12 patients were reviewed. After initial injury, the patients were in the surgical intensive care unit. Reoperations were performed nine months (mean) after discharge from this facility. The reasons for reoperation were closure of enteric fistula (five patients) and closure of an ostomy (seven patients). The abdominal wall was reconstructed in nine patients. In the other three patients, the abdomen was entered through a lateral incision and the bowel was reanastomosed. RESULTS: All of the patients survived. There were five complications. Two patients had ischemic skin grafts successfully treated by hyperbaric oxygen therapy (HBO). Two patients had ischemic skin flaps that were covering mesh. They responded to HBO with minimal slough of superficial tissue. One patient had a low output fistula that closed after two weeks of total parenteral nutrition. CONCLUSIONS: A history of an open abdomen is not a contraindication to later operation. Bowel continuity can be restored and abdominal wall reconstruction can be performed safely. This can be done as early as three to four months after recovery from the original injury.

Laparoscopic-assisted colostomy closure after Hartmann's procedure.

PURPOSE: The aim of the study was to review our experience with colostomy closure after Hartmann's procedure and the possible impact of laparoscopic colostomy closure. METHODS: A retrospective review of hospital stay after colostomy closure by laparotomy in the last four years was conducted. A chart review of patients undergoing laparoscopic colostomy closure after Hartmann's procedure since the introduction of operative laparoscopy at our institution was also done. RESULTS: One hundred twenty patients had colostomy closure carried out by the trauma service at the University of Miami/Jackson Memorial Hospital. In thirty-seven patients, colostomy closure was associated with other surgical procedures such as ventral herniorrhaphy, delayed closure of the open abdomen, ureteroneocytostomy, and so forth, or they underwent loop colostomy closure. These patients were excluded from further review. Sixty-five patients underwent reversal of Hartmann's procedure by laparotomy. They had an average hospital stay of 9.5 days (range, 6 to 34 days). This group of patients had colostomy closure prior to the introduction of operative laparoscopy in our institution. With increased laparoscopy experience, laparoscopically assisted Hartmann's reversal has been attempted in 18 patients and completed in 14 patients. The average hospital stay in the laparoscopically completed group was 6.3 days (range, 4 to 10 days). This group had a 0 percent mortality and a 14.3 percent morbidity. This compares favorably to recently reported series of colostomy closure by laparotomy. CONCLUSION: Laparoscopically assisted Hartmann's reversal results in comparable morbidity, but may be associated with shorter hospital stay when compared with laparotomy.

Laparoscopic assisted colorectal surgery.

Forty-nine consecutive patients underwent laparoscopic assisted colorectal surgery for benign and malignant lesions of the colon. Thirty-eight of the 49 operations (78%) were completed successfully with laparoscopic assistance. A large tumor bulk or dense adhesions were the most common reasons for conversion to laparotomy. Twenty-eight of the 38 patients (74%) in the laparoscopically completed group were tolerating a diet by postoperative day 2, and 31 (82%) passed flatus or a bowel movement by the third postoperative day. The mean postoperative hospital stay for this group was 4.8 days, which compared very favorably to that reported in the literature for traditional open colorectal operations. Twelve patients developed complications, for a 24% morbidity in the series. However, only 3 (6%) of these complications were related to the laparoscopic part of the procedure. Inspection of the pathologic specimens revealed adequate margins and a lymph node harvest that averaged 11 nodes per specimen. We concluded that laparoscopic assisted colorectal surgery is a safe and feasible technique, which may be associated with a faster return of bowel activity and a shorter hospital stay. Although the extent of resection appears comparable to that of laparotomy, it is too early to assess long-term outcome when it is applied in the treatment of malignancy.

Management of lower extremity arterial trauma.

Extremity vascular trauma is common in most urban trauma centers and controversy remains about the optimal management of arterial injuries. We examined the records of 188 patients who had lower extremity arterial trauma from September 1987 to April 1992 to help clarify these issues. There were 142 (75.5%) gunshot wounds, 18 (9.6%) stab wounds, 5 (2.7%) shotgun wounds, and 23 (12.2%) patients with blunt trauma. There were 43 (22.9%) associated venous injuries. There were 10 repair failures in the acute postoperative period. There were no repair failures for the iliac artery. Three failures involved the superficial femoral artery (SFA), six were popliteal, and one tibial. Vein and polytetrafluoroethylene (PTFE) grafts were used to repair the SFA with equal success. Repair of the popliteal artery with PTFE failed in four of five cases, while vein grafts failed in only 2 of 19 cases (p < 0.01). Graft failure was associated with blunt trauma in 8 of 23 patients (35%), and always resulted in amputation. Penetrating injuries accounted for only 2 of 165 (1.2%) failures and were successfully redone with no amputations. Venous injury was present in all SFA failures. Popliteal vein injury was present in two PTFE and two vein grafts that failed. There were no infections of vein or PTFE grafts. In conclusion, PTFE and vein have equal graft patency for the repair of the iliac and femoral arteries. However, the patency of PTFE was significantly worse in the popliteal location. Vein grafts should be used for repair of this vessel. Graft failure and amputation were more common with popliteal and tibial injuries from blunt mechanisms.(ABSTRACT TRUNCATED AT 250 WORDS)

Laparoscopic treatment of colovesical fistulas: technique and report of two cases.

Colovesical fistulas are a serious complication of diverticular disease. Management by one-stage resection and anastomosis has resulted in lower morbidity and shorter hospital stay. Nevertheless, hospital time remains long, approaching an average of 2-3 weeks. Here we describe our technique of laparoscopic approach to colovesical fistulas. Our initial experience suggests that this is a safe operation with minimal pain, absent ileus, and a short postoperative stay.

Laparoscopy in abdominal gunshot wounds.

The role of laparoscopy in the evaluation of abdominal trauma continues to evolve. It has been successfully used in blunt and penetrating trauma. We report our experience with diagnostic laparoscopy in 28 patients with abdominal gunshot wounds. We found a 100% accuracy and a 0% morbidity in patients with negative laparoscopy. We report a case in which laparoscopy was used to demonstrate an isolated nonbleeding liver injury due to a gunshot wound to the abdomen. Nontherapeutic laparotomy was avoided.

Thoracoscopy in the evaluation and management of thoracic trauma.

Video-thoracoscopy was used to evaluate and manage patients after thoracic trauma. It was used in 29 patients. Indications included retained hemothorax in 16 patients, empyema in 11, evaluation for the source of thoracic bleeding in 1, and an airleak in 1. The mechanism of injury was blunt trauma in 8 cases, 10 with stab wounds, and 11 with gunshot wounds. In blunt trauma, thoracoscopy was carried out an average of 11.7 days post injury, chest tubes were removed after an average of 7 days post thoracoscopy, and discharge averaged 10.7 days after thoracoscopy. The failure rate was 12.5% with no mortality. In stab wounds, it was carried out an average of 8.8 days post injury, chest tube removal occurred after 6.1 days, and discharge averaged 7.8 days after thoracoscopy. The failure rate was 20% with no mortality. In gunshot wounds, it was carried out an average of 7.5 days after injury, chest tubes were removed after 9.9 days, and discharge averaged 16 days post thoracoscopy. The failure rate was 9% with a mortality of 9%. Overall, the failure rate for thoracoscopy was 13.8% (4/29). The mortality rate was 3.5% (1/29). It was successfully performed up to 30 days post injury. It proved to be effective in the management of empyema, evacuation of clotted hemothorax, and diagnosis of ongoing thoracic bleeding.
