Does the complication rate increase in laparoscopic cholecystectomy for acute cholecystitis?

BACKGROUND: Laparoscopic cholecystectomy (LC) has replaced open cholecystectomy for the treatment of gallbladder disease. Despite the well-accepted success of LC in chronic cholecystitis, the efficacy of this technique has been subject to some debate in acute cholecystitis (AC). This study was designed to evaluate our institution's experience with LC for AC and chronic symptomatic calculous cholecystitis (CC), based on complication and conversion rates to open surgery. PATIENTS AND METHODS: The records of 1158 patients with LC from September 1991 to December 2001 were analyzed. The parameters of age, gender, early and late complication rates, and conversion rates from LC to open cholecystectomy were compared in patients with AC and CC. RESULTS: During the study period, LC was performed in 1158 patients. Of these, 162 patients had AC (group 1) and 996 patients had CC (group 2). The conversion rates were 4.3% (7/162) in group 1 and 2.4% (24/996) in group 2. The complication rates were not significantly different (5.6% in group 1, 5.1% in group 2, P > 0.05). Difficulty in dissection around Calot's triangle and obscure anatomy were the main reasons for conversion to conventional open surgery. The mortality rate was 1.2% in group 1 and 0.01% in group 2. CONCLUSION: LC appears to be a reliable, safe, and effective treatment modality for AC and CC. The surgical approach should be performed carefully because of the spectrum of potential hazards of the laparoscopic procedure. Conversion and complication rates are similar in both AC and CC groups, and improve as surgeons gain experience.     

Cryopreserved iliac artery allograft for primary arterial revascularization in adult liver transplantation

Arterial allograft represents a material of choice for primary arterial revascularization in liver transplantation (LT) when interposition of a vascular conduit is required. In case of non-availability of such graft, the use of cryopreserved vessels should be an interesting option. Three patients were grafted using a cryopreserved iliac artery allograft (CIAA) previously harvested and stored at -140°C in a tissue bank. An auxiliary partial LT was performed in one patient for acute liver failure. During follow-up, an efficient regeneration of the native hemi-liver was observed while atrophy of the auxiliary graft occurred, leading to functional portal vein and hepatic artery thrombosis at six and nine months, respectively. Two other patients presented with celiac trunk compression because of arcuate ligament without available arterial allograft in the donor. Late arterial thrombosis occurred at six months in one patient without impairment of graft function. The last patient was alive and symptom free 29 months after LT with a patent cryopreserved arterial conduit. Our preliminary results suggest that CIAA might represent an efficient solution as vessel interposition for primary arterial hepatic revascularization in LT setting when no other suitable graft is available. However, long-term patency of CIAA remains questionable.     

Microsurgical excision of symptomatic sacral perineurial cysts: a study of 15 cases

BACKGROUND: The widespread use of magnetic resonance imaging (MRI), now the first line investigation for back and leg pain, reveals cystic sacral lesions more often than myelography did in the past. There is agreement that symptomatic perineurial sacral cysts should be treated surgically. However, it is still debated whether the preference should be given to the curative option, consisting of excision of the cyst with duraplasty, or to drainage of the cyst to relieve symptoms. In this retrospective study the efficacy of microsurgical cyst resection with duraplasty is evaluated. METHODS: In 15 patients presenting with pain and neurologic deficits, myelography and/or MRI detected sacral cysts. The clinical features suggested that the space-occupying lesions caused the disturbances. Microsurgical excision of the cyst along with duraplasty or plication of the cyst wall was performed in all the cases. Postoperative care included bed rest and CSF drainage for several days. RESULTS: In 13 out of 15 patients the preoperative radicular pain disappeared after surgery. The 2 patients with motor deficits and the 6 patients with bladder dysfunction recovered completely. In all except 1 of the 10 patients complaining of sensory disturbances a significant improvement was achieved. No complications were observed. CONCLUSION: Microsurgical excision of the cyst combined with duraplasty or plication of the cyst wall is an effective and safe treatment of symptomatic sacral cysts and, in the view of the authors, the method of choice.     

Multiple rice body formation accompanying the chronic nonspecific tenosynovitis of flexor tendons of the wrist

Rice body formation is generally a rare disorder related to rheumatoid arthritis. It can also be observed in cases of systemic lupus erythematosus, seronegative arthritis, infectious arthritis (tuberculosis, atypical mycobacterial infection), nonspecific arthritis, and osteoarthritis. It is generally located within joints or bursae. Multiple rice bodies of tendon sheaths are rarely encountered. Rice body formation may also be encountered without underlying systemic disorders. We present a case of multiple rice body formation that accompanied chronic nonspecific tenosynovitis of the flexor tendons of the wrist.     

Minimally disruptive decompression and transforaminal lumbar interbody fusion.

BACKGROUND: Posterior spinal procedures through tubular exposures have been described. However, tubes restrain visibility and require co-axial instrument manipulation, increasing difficulty and potentially compromising surgical results. An independent-blade retractor system overcomes the obstacles of working through a tube and has been used to perform minimally-disruptive decompression and instrumented tranforaminal lumbar interbody fusion (TLIF). PURPOSE: To evaluate the advantages to patient recovery and surgical efficacy of this technique. METHODS/RESULTS: Retrospective review of technique employing a minimally-disruptive approach to decompression and transforaminal lumber interbody fusion (TLIF). CONCLUSIONS: Minimally-disruptive decompression and instrumented TLIF can be performed in a safe and effective manner using an independent-blade retractor system. Relative to traditional-open techniques, surgical goals can be accomplished, but with the benefits of minimally-disruptive surgery.     

Oestrogen-soaked vaginal packing for decubitus ulcer in advanced pelvic organ prolapse: a case series

Introduction

Cervicovaginal decubitus ulceration is a well-known complication of advanced pelvic organ prolapse (POP). There is no consensus for its management. This case series describes the outcome of using repeated vaginal packs soaked with oestrogen cream to reduce POP and promote decubitus ulcer healing. We aimed to investigate the speed of ulcer healing and endometrial safety with this regimen.

Methods

This was a retrospective study of patients with stage 3 or 4 POP and intact uterus with decubitus ulcer who were planned for surgery that included hysterectomy after ulcer healing. Vaginal packs are replaced at least biweekly—or more frequently if extruded—until ulcer resolution.

Results

Thirteen patients were studied. Mean age was 69?±?6 years and mean duration of menopause was 19?±?6 years. Nine patients had a single ulcer and four had multiple ulcers. Mean ulcer diameter was 2.8?±?1.5 cm and mean duration for ulcer healing was 26?±?14 days. Hysterectomy and pelvic floor reconstruction was performed a median of 5 (range 0–153) days after ulcer healing was first noted. Histopathological examination of the endometrium following hysterectomy showed three specimens with endocervical hyperplasia; one had concurrent proliferative endometrium, two had simple endometrial hyperplasia and another two had proliferative endometrium.

Conclusion

Oestrogen-soaked vaginal packing is a viable option for managing a decubitus ulcer in advanced POP. We document a measurable impact on the endometrium with this short-term preoperative regimen. Further research is needed to evaluate its efficacy in promoting ulcer healing and endometrial safety.

     

Timing of surgical treatment for type III supracondylar humerus fractures in pediatric patients

Background  Type III supracondylar humeral fracture is a common cause of emergency hospitalization among children requiring surgical treatment. The configuration of the internal fixation material, surgical technique, and optimal timing of surgery (TS) have always been popular topics of debate. The TS in uncomplicated cases is usually determined by surgeons. Methods  In this study, we prospectively followed children with type III supracondylar fractures. We aimed to clarify the effects of injury side, gender, and post-injury delay on switching to open surgery and the ease of the reduction. Results  Based on our results, the probability of switching to open surgery increased by a factor of 4 every 5 h beginning 15 h after injury. Open surgery was necessary after 32 h. Conclusion  Reduction became technically more difficult as TS increased.     

Left ventricular systolic and diastolic function and carotid intima-media thickness in pediatric dialysis patients

Background  Cardiovascular complications are common in patients with end-stage renal disease (ESRD). We aimed to investigate left ventricular (LV) function and carotid intima-media thickness (cIMT) in children and adolescents with ESRD. Methods  This study included 38 ESRD patients (15 hemodialysis and 23 peritoneal dialysis) and 17 age- and sex-matched healthy subjects. Results  The ESRD patients had significantly lower mean mitral E/A ratio, and higher left ventricular mass index (LVMI) and cIMT than the control group. Compared with PD patients, HD patients had worse LV diastolic function. In stepwise linear regression analysis, LVMI (P = 0.043) and hemoglobin (P = 0.015) turned out to be independent variables for predicting diastolic dysfunction (reduced E/A ratio), and the only significant predictor of cIMT was indexed diastolic blood pressure (DBP) (P = 0.035). Conclusion  Cardiovascular structure and function abnormalities are also common in pediatric dialysis patients, as in adults. Furthermore our data indicated that hemodialysis was disadvantageous for preserving LV diastolic function as compared with peritoneal dialysis.     

One-stage Transthoracic Operation for the Treatment of Right Lung and Liver Hydatid Cysts

In this study we reviewed our experience of hydatid disease of the lung and the liver and discussed the safety and the follow-up results of the one-stage operation. Between 1990 and 2004, 142 patients with pulmonary hydatid disease underwent operation in our clinic. Of these, 27 (19%) patients had cysts located on the dome of the liver, treated with phrenotomy through a right thoracotomy. Hydatid cysts located in the lungs were managed by means of cystotomy. For liver cysts, cystotomy and the inversion of the cavity with sutures was the surgical method of choice, and a drain was left in place. The pulmonary cysts of 12 (8.4%) patients were bilateral and 5 (3.5%) patients had prior surgical treatment of hepatic (n = 1) or pulmonary (n = 4) hydatid cysts. The liver cysts were approached transdiaphragmatically after the lung cysts were excised in 27 (19%) patients. In patients with pulmonary cysts, cystotomy, with or without capitonnage was performed on 123 (86.6%) patients, and wedge resection was performed on 11 (7.7%), segmentectomy was performed on 6 patients (4.2%), and lobectomy was performed on 2 (1.4%) patients. There was no mortality, and only a small number of complications were encountered: empyema in 3, excessive biliary drainage in 2, and bronchopleural fistula in only 1. We suggest that the extraction of pulmonary and hepatic cysts simultaneously through the transthoracic route is a useful and safe surgical technique. This technique also prevents the need for a second operation.
