Urinary and sexual dysfunction rates and risk factors following rectal cancer surgery

OBJECTIVE

The aim of this study was to express the effects of demographic characteristics, the type of the surgery, tumour characteristics and adjuvant therapy on urinary and sexual dysfunctions.

MATERIALS AND METHOD

Pre-operational urinary and sexual dysfunctions of the patients were evaluated by using the surveys prepared according to International Prostate Symptom Score (IPSS) and International Index of Erectile Function (IIEF) in men and Index of Female Sexual Function (IFSF) in women.

FINDINGS

A total of 56 patients were included in the study; 20 of them were women and 36 of them were men. The mean age was 56. Abdominoperineal resection (APR) was performed on 11 patients, and low anterior resection (LAR) was performed on 45. The post-treatment IPSS classes were worsened at a rate of 12.7 % compared to the pre-treatment. The mean post-treatment sexual dysfunction score of both men and women were decreased by 27.5 and 17.8 %, respectively. Rectal tumours located in the lower part resulted in more sexual dysfunction.

CONCLUSION

The tumour in the 1/3 lower part of the rectal area was determined to be the most effective factor that caused both urinary and sexual dysfunction. Patients should be informed about the urinary and sexual dysfunctions in the pre-operative consultations.

D-Dimer in the Early Diagnosis of Acute Mesenteric Ischemia Secondary to Arterial Occlusion in Rats

BACKGROUND

Early diagnosis of mesenteric ischemia can be life saving. The aim of this study is to investigate the time-dependent diagnostic value of plasma D-dimer and other ancillary laboratory evaluations such as creatine phosphokinase, lactic dehydrogenase, aspartate aminotransferase, alanine aminotransferase, amylase, and leukocyte count in an experimental superior mesenteric arterial occlusion (SMA-O) model in rats.

METHODS

Forty male Wistar-Albino rats were separated into 4 groups: 2-, 4-, 6-, and 12-hour SMA-O groups. After laparotomy, the SMA was identified and ligated for 2, 4, 6 and 12 h in the 4 respective study groups. Blood samples were taken for laboratory tests 2 h after laparotomy in the control group and at the end of the ischemic period in the study groups.

RESULTS

The longer the duration of mesenteric ischemia, the higher were the serum D-dimer levels in the study groups, and statistical significance was obtained at 2 h (p = 0.021). Sensitivity, positive predictive value, negative predictive value, and accuracy of the relation were 88.8, 88.8, 100 and 90%, respectively. Leukocyte count was significantly higher than controls after 12 h. No other laboratory parameter correlated positively with the duration of mesenteric ischemia.

CONCLUSION

Serum D-dimer measurements may be a valuable diagnostic parameter in the early diagnosis of mesenteric ischemia.

Missed injuries in military patients with major trauma: original study

OBJECTIVE

The incidence and subsequent outcomes of missed injuries and the primary factors contributing to each missed injury were analyzed.

METHODS

Records of 709 trauma patients were reviewed between December 2003 and December 2004. Demographic data were compared and analyzed for two patient groups: those with multiple injuries diagnosed in 24 hours and those with multiple injuries diagnosed in >24 hours.

RESULTS

Fifty-two missed injuries were determined in 34 (4.8%) patients. There were significant differences between the patients with and without delayed diagnoses, including the mean injury severity scores (23 vs. 16.9), morbidity, and mortality (p < 0.05 for all). Among 69 contributing factors identified, 28 (40.6%) were unavoidable and 41 (59.4%) were potentially avoidable.

CONCLUSIONS

Missed injuries could usually be encountered in the most seriously injured patients, particularly in those with altered levels of consciousness. Missed injuries were mostly avoidable and most were the result of inadequate clinical examination.

The survival effect of E-cadherin and catenins in colorectal carcinomas

AIM

The E-cadherin/catenin complex plays an important role in epithelial tissue architecture. Decreased expression of cell adhesion molecules (E-cadherin, α-, β- and γ-catenin) have been reported to correlate with invasive behaviour. The aim of this study was to investigate the relation between the expression of adhesion molecules and clinicopathological characteristics and survival in colorectal carcinoma.

METHOD

The expression of adhesion molecules were studied by immunohistochemistry in 138 colorectal carcinomas.

RESULTS

The mean age of the patients was 65 years (range: 21-89 years). In primary carcinomas, a reduction in membranous expression of E-cadherin, α-catenin, β-catenin, γ-catenin was demonstrated (70%, 68%, 73%, 77%, respectively). Nuclear expression of β-catenin was found in eight (5%) patients. Decreased membranous β- and γ-catenin expression significantly correlated with tumour differentiation (P = 0.013, P = 0.03, respectively). There was a significant association between advanced stage of the tumour and decreased membranous α-catenin expression (P = 0.012). Decreased E-cadherin and β-catenin membranous expression correlated with short survival following curative resection of the primary tumour (P = 0.04, P = 0.03, respectively).

CONCLUSION

The decreased membranous expression of E-cadherin and β-catenin and increased cytoplasmic expression of β-catenin might be used as a prognostic marker to monitor patients with colorectal cancer.

Comparison of laparoscopic and open surgery for total rectal prolapse

PURPOSE

Total rectal prolapse is a devastating disorder causing constipation and anal incontinence. We compared open and laparoscopic surgical approaches in a limited series.

METHODS

The subjects of this study were 23 patients who underwent laparoscopic procedures (LP group) and 17 patients who underwent open procedures (OP group) for rectal prolapse. We assessed the preoperative colonic transit time, postoperative pain scoring, pre- and postoperative anal functions, and changes in constipation and related symptoms.

RESULTS

The median operation time was 140.8 min for the LP group and 113.1 min for the OP group (P = 0.037). The median postoperative hospital stay was 4.8 days after the LPs and 9.6 days after the OPs (P = 0.001). Less analgesia was needed in the early postoperative period after the LPs (P = 0.007). While more than 70% improvement in continence was seen in the patients who underwent OPs, it was about 85% in those who underwent LPs. Improvement in constipation and related symptoms were similar in both groups. More than 30% of patients still suffered from hard stools and other symptoms of constipation. The colonic transit times were reduced in about 50% of patients who had suffered constipation in both groups. There was no incidence of recurrence in the median follow-up period.

CONCLUSION

Although transabdominal rectopexy has been performed conventionally for rectal prolapse for many years, laparoscopic rectopexy and laparoscopic resection rectopexy are associated with lower morbidity and less postoperative pain. We eliminated the total prolapse and cured incontinence in almost all patients, with a short hospital stay.

Colonic Volvulus Associated with Chilaiditi?s Syndrome: Report of a Case

Hepatodiaphragmatic interposition of the intestine, known as Chilaiditi's syndrome, is a rare and often asymptomatic anomaly, typically found as an incidental radiographic sign. We report a case of Chilaiditi's syndrome associated with transverse colon volvulus, predisposed by segmental agenesis of the right lobe of the liver. A 45-year-old man presented with a 2-day history of abdominal pain, nausea, vomiting, and constipation. Plain chest X-ray and abdominal computed tomography showed colonic interposition and segmental agenesis of the right lobe of the liver. Laparotomy revealed a clockwise volvulus of the transverse colon associated with interposition and incarceration of the colon through the space of the agenetic segment of the liver. The transverse colon, which was adherent to the agenetic space in the liver and diaphragm, was dissected away and repositioned, and the volvulus was reduced. To our knowledge, this is only the sixth reported case of a colonic volvulus associated with Chilaiditi's syndrome and the first case associated with segmental agenesis of the right lobe of the liver.

Simultaneous determination of dextrorphan and guaifenesin in human plasma by liquid chromatography with fluorescence detection

A sensitive liquid chromatographic (LC) method was developed and validated for the simultaneous determination of dextrorphan and guaifenesin in human plasma using fluorescence detection. Dextrorphan and guaifenesin were extracted from plasma by a liquid-liquid extraction procedure using chloroform containing laudanosine as the internal standard. A cyano column (15 cm x 46 mm i.d., Spherisorb 5-CN) and a mobile phase containing acetonitrile-triethylamine-distilled water (10:1:89, v/v/v) (pH 6) were used. The concentration-response relationship for dextrorphan was found to be linear over a concentration range of 23-515 ng ml-1 with a lower limit of detection of 20 ng ml-1; the accuracy of the method would fall (95% confidence limit) within 9.53% and 11.07% of the true value for the inter-and intra-day, respectively; the inter- and intra-day precision, as measured by RSD, ranged from 1.88% to 30.07% (mean 2.28%) and from 4.69% to 7.51% (mean 5.67%) over the dynamic concentration range of the method (33-326 ng ml-1). The concentration-response relationship for guaifenesin was found to be linear over a concentration range of 181-8136 ng ml-1 with a lower detection limit of 30 ng ml-1; the accuracy of the method would fall (95% confidence limit) within 9.78% and 8.04% of the true value for the inter- and intra-day, respectively; the inter- and intra-day precision, as measured by the RSD, ranged from 2.55 to 6.07% (mean 3.90%) and from 3.12 to 3.90% (mean 3.52%) over the dynamic concentration range of the method (435-6430 ng ml-1).(ABSTRACT TRUNCATED AT 250 WORDS)

Poland's syndrome and gastric cancer: report of a case

Poland's syndrome, a rare congenital anomaly characterized by pectoralis muscle defect and ipsilateral hand abnormalities, has been reported in association with various malignancies. Gastric cancer associated with Poland's syndrome has not been described previously. To our knowledge, the case of the 21-year-old man we describe herein represents the first report of Poland's syndrome associated with gastric cancer. Although previously there was no certain evidence that linked Poland's syndrome and cancer, elucidating the molecular mechanisms that cause this syndrome may further clarify the relationship between Poland's syndrome and malignancies. At least, these associations confirm the relationship between Poland's syndrome and malignancies, and require oncologic awareness.

Comparison of modified Limberg flap transposition and lateral advancement flap transposition with Burow's triangle in the treatment of pilonidal sinus disease

BACKGROUND

Although many options exist for surgical treatment of pilonidal sinus disease (PSD), consensus has not yet been achieved, as all surgical methods have various rates of complications, postoperative infection, and recurrence.

METHODS

This study was a prospective, randomized, clinical trial, and was conducted with consecutive 100 patients admitted to Ankara Military Hospital General Surgery Service for treatment of PSD from May 2013 to August 2013. This study compared two surgical treatments for PSD: modified Limberg flap transposition and lateral advancement flap transposition with Burow's triangle. The patients received surgical treatment with either modified Limberg flap transposition (n = 50) or lateral advancement flap transposition with Burow's triangle (n = 50). Clinical healing period, length of hospital stay, operative time, postoperative complications including recurrence, wound dehiscence, and surgical site infection, as noted during postoperative follow-up period; Visual Analog Scale scores for pain.

RESULTS

The mean follow-up period was 12 months. No significant differences were observed between the 2 groups in length of hospital stay (P = .515), operative time (P = .175), wound dehiscence (P = .645), and Visual Analog Scale pain scores (P = .112). The mean operative times were 42.5 minutes in the modified Limberg group and 40.0 minutes in the lateral advancement group.

CONCLUSIONS

Although lateral advancement flap transposition with Burow's triangle is used less often than modified Limberg flap transposition, we could not determine a parameter that was statistically different such as operative time, postoperative complication, or the length of hospital stay. Hence, the lateral advancement flap is as viable an option as other more preferable techniques in the treatment of PSD, which particularly settled on the upper segment without a deep natal cleft.

A rare complication after thyroidectomy: perforation of the oesophagus: a case report

Perforation of the cervical oesophagus after thyroidectomy is an exceptionally rare complication. Total thyroidectomies, particularly for recurrent cases might possess an increased risk. Although rare, it has high mortality and morbidity. A patient that developed oesophagus perforation after a total thyroidectomy in a peripheral hospital for recurrent nodular goitre was treated and followed-up in our clinic. This well-documented case is discussed in conjunction with the information presented in the literature.

The impact of laparoscopic resection rectopexy in patients with total rectal prolapse

Total rectal prolapse is a disabling disease. The aim of this study was to evaluate pain management, hospital stays, constipation, and continence status among military personnel who underwent laparoscopic surgery. Forty patients (mostly men) underwent laparoscopic rectopexy (LR) or laparoscopic resection rectopexy (LRR). Colonic transit time, postoperative pain scores, preoperative and postoperative anal function, and changes in constipation were assessed. The median operation times for LR and LRR were 126 and 223 minutes, respectively. The median postoperative hospital stays were 3 and approximately 6 days for LR and LRR, respectively. Patients needed fewer analgesics in a short postoperative period. However, there was no difference between the two groups in analgesic requirements. Continence improved for approximately 71% of patients, but constipation was treated for 50% of affected patients. No recurrences were noted in the follow-up periods, which were 13 and 22 months for the LRR and LR groups, respectively. The quality of life for the patients who underwent LR was not as good as that for the patients who underwent LRR, at the end of 1 year. We eliminated total rectal prolapse and almost cured incontinence by using laparoscopy, although the disadvantageous aspects were long operation times and suboptimal healing with respect to constipation and related symptoms. LRR is the more feasible procedure, with the emphasis on elimination of incontinence and constipation, producing a better quality of life for patients, in addition to short hospitalizations, necessity for analgesia for a short time, and return to hard training field activities in a short time among military personnel.

Mild and Severe Anal Incontinence after Lateral Internal Sphincterotomy: Risk Factors, Postoperative Anatomical Findings and Quality of Life

<i>Aim:</i> This study aims to evaluate the risk factors for incontinence after lateral internal sphincterotomy (LIS) and assess quality of life in different levels of incontinence. <i>Methods:</i> All consecutive patients (n = 253) with chronic anal fissure who underwent LIS between 2003 and 2006 were retrospectively reviewed. All patients were questioned for possible anal incontinence according to the Wexner Incontinence Score (WIS). Demographics, vaginal delivery history, additional procedures and surgeon’s experience were evaluated as risk factors. Endoanal ultrasound (EUS) was performed in incontinent patients to assess the thickness of the remaining internal sphincter and to evaluate any injury in the external sphincter. Quality of life was questioned with SF-36. <i>Results:</i> Twenty-eight (11.7%) patients suffered from incontinence (mean WIS = 3.6 ± 2.5). The search for a risk factor was unsuccessful when continent and incontinent groups were compared. In subgroup analyses, patients were found to be suffering from mild (WIS <5, n = 19) or severe (WIS >5, n = 9) incontinence. Vaginal delivery history was found more often in the severely incontinent subgroup than in the continent group (p < 0.05). Also, vaginal delivery history and the additional procedures were more frequently observed in the severely incontinent subgroup than in the mildly incontinent subgroup. EUS did not find any external sphincter injury in these cases. WIS had negative correlations with the physical and mental component scores of SF-36. <i>Conclusion:</i> In our opinion, the threat for incontinence is unpredictable; however, vaginal delivery history may increase the risk of severe incontinence.

Early Outcomes of Laparoscopic Procedures Performed on Military Personnel With Total Rectal Prolapse and Follow-up

Total rectal prolapse is a disorder frequently associated with constipation and anal incontinence. The aim of this study was to evaluate the outcomes of the complications, pain management, hospital stay, constipation, and anal functions of the patients undergoing 2 types of laparoscopic surgical approaches. In this study, 33 patients underwent either laparoscopic rectopexy or hand-assisted laparoscopic resection rectopexy. Preoperative colonic transit time, defecation, postoperative pain scoring, pre-postoperative evaluation of the anal function, and the changes in constipation and relating symptoms were assessed. Postoperative evaluation had been performed at the sixth week and the twelfth month. Median operation time was 137 minutes for rectopexy and 230 minutes for resection rectopexy group. Median postoperative hospital stay was 3 days for patients with rectopexy and 7 days for patients with resection rectopexy. Patients needed painkillers in short postoperative period for pain management in both groups. Continence was improved in 11 of 13 patients (84.6%) in a year after laparoscopic surgery. In 15 patients (45.5%), preoperative constipation either remained in the same or became worse in 7 (21.1%) in a year after surgery. No patient developed recurrence in the median follow-up period, which was about 15 months. Laparoscopic rectopexy and resection rectopexy in the young aged patients working the Army are carried out with less morbidity rate. We eliminated the total prolapse and cure incontinence in almost all patients. In addition to constipation was reduced by laparoscopic surgical approaches in a short time hospitalization with short time painkiller need.

Use of vacuum-assisted closure (VAC™) in high-energy complicated perineal injuries: analysis of nine cases

Our study reviewed nine patients who were treated with the VAC™ Abdominal Dressing System after suffering pelvic fractures and soft tissue loss after high-energy pelvic trauma. Between March 2008 and August 2009, our clinic treated nine patients with complicated perineal injuries from high-energy pelvic trauma with multiple irrigation and debridement procedures and broad-spectrum antibiotics. Protective ostomies were created for all nine patients. Required interventions were made for associated injuries, and VAC™ application was started. All patients were male, with an average age of 24·3 (range 21-32) years, and a mean injury severity score of 36·4 (range 16-59). Wound diameters ranged from 15 to 30 cm, and wound depths ranged from 5 to 25 cm. The injuries included one traumatic bilateral hemipelvectomy, and three unilateral and two bilateral lower extremity amputations. Intensive care unit length of stay averaged 12 (6-19) days, and average hospital length of stay was 44·12 (31-64) days. Beginning at an average of day 17 (±5·9 days) post-injury, wound cultures detected no bacterial colonisation. One patient died on the sixth day after injury from septic complications. Two patients' wounds were closed by primary closure, and six patients' wounds were closed by split thickness grafts after an average of 31·4 (17-50) days. Optimal treatment of high-energy perineal injuries requires early and extensive debridement and rich irrigation. The application of the VAC™ system as temporary coverage of large complex wounds in the pelvic region enhances wound healing and facilitates an early grafting process.

Comparison of single-incision and conventional laparoscopic cholecystectomy in terms of quality of life, body image, and cosmesis

Background

Clinical studies indicate that single-incision laparoscopic cholecystectomy (SILC) has many advantages over conventional laparoscopic cholecystectomy (CLC), such as improved cosmesis, reduced postoperative pain, and shorter hospital stay. The aim of this study was to compare quality of life, body image, and cosmesis between single-incision laparoscopic and conventional laparoscopic approaches in patients undergoing cholecystectomies.

Subjects and Methods

This retrospective study between SILC and CLC and was conducted among 58 patients undergoing SILC and CLC from January 2011 to March 2013 in Turkey. After the surgery, the EuroQol-5 Dimension Questionnaire (EQ-5D™), and body image questionnaire (BIQ) were administered to the patients.

Results

Differences between the early and late postoperative scores in the EQ-5D were statistically significant (P < 0.001). Differences between most BIQ areas favored SILC, especially regarding cosmesis (P = 0.016); SILC patients had higher satisfaction with their scar's appearance.

Conclusion

SILC is a promising alternative to traditional laparoscopic cholecystectomy in terms of quality of life, body image, and cosmesis in selected patients.

Bioavailability of dextromethorphan (as dextrorphan) from sustained release formulations in the presence of guaifenesin in human volunteers

A multiple dose bioavailability study with six healthy male human volunteers was conducted. The bioavailability of an experimental sustained release tablet containing dextromethorphan hydrobromide (DXP-HBr), was compared with a marketed sustained release DXP-HBr suspension in a three-way crossover study. Plasma samples, collected serially after oral drug administration, were analysed for the major metabolite of dextromethorphan (DXP), dextrorphan (DX), using a specific HPLC method with fluorescence detection. The bioavailability parameters; area under the concentration-time curve (AUC), maximum plasma concentration (Cmax), and time to peak (Tmax), were obtained from the plasma concentration-time data. Additionally, pharmacokinetic parameters such as mean residence time (MRT), accumulation factor (R), fluctuation index (Fi), total body clearance (Cl), and the average concentration (C) were estimated by using model independent kinetics approach. Analysis of variance of the data revealed that the presence of guaifenesin in the test formulation does not appear to have a statistically significant (p > 0.05) effect on the bioavailability of dextromethorphan as dextrorphan. The relative bioavailability of the tablet dosage form with respect to the suspension was found to be 113% on Day 1 and 110% on Day 6.

Overlapping repair in patients with anal sphincter injury

OBJECTIVE

The aim of this study was to demonstrate the improvement of anal canal function after overlap sphincter repair and confirm that this treatment option is superior in patients with nonobstetric sphincter damage.

SUBJECTS AND METHODS

From 1998 to 2003, 44 women who underwent overlapping sphincter repair were enrolled in this study. The women were allocated to one of two groups, obstetric trauma (n = 31) and nonobstetric (perineal) trauma (n = 13). Both groups were compared in terms of age, operation time, number of deliveries, hospital stay, need for analgesics, complication rate, pre- and postoperative outcomes of anal manometry and quality of life, using the fecal incontinence severity index and a questionnaire for fecal disorders.

RESULTS

Anal canal length was significantly extended postoperatively in both groups compared to preoperative length. Eight-week postoperative resting and squeeze pressures were significantly higher than preoperative pressures in both patients with nonobstetric and obstetric sphincter injury. Although significant increase was seen in both groups, the mean postoperative resting and squeeze pressures at 1 year were rather high in patients with nonobstetric sphincter injury. At the end of a year of follow-up, overall satisfaction of the repair was about 82%.

CONCLUSION

Overlap sphincter repair was feasible, although patient satisfaction was slightly less in the obstetric than in the nonobstetric trauma group. The improvement of anal function at 20- to 24-month follow-up is attributed to both high squeeze pressure and broad anal canal.

Non-urgent patients in an Emergency Medical Service

BACKGROUND

Emergency Medical Services (ES) are medical-surgical facilities where extremely ill patients, victims of accidents, intoxications and other urgent clinical situations should be rapidly and efficiently attended. However, a worldwide experience is that a large proportion of patients who require attention in an ES do not qualify as emergencies and they obstruct the possibilities of other patients that should be attended immediately.

AIM

To evaluate the medical records in our ES and to assess whether patients understand what is a true emergency and which is the role of an ES.

METHODS

Patients attended in the ES of Haydarpasa Military Teaching Hospital in 2001-2002 were classified according to their diagnosis. A random sample of patients and relatives were surveyed about why they required medical attention in the ES.

RESULTS

77,134 patients (39,327 female, 51%) were attended. The most common illness diagnosed was upper respiratory tract infection (18,423 patients, 23.9%). The true emergency condition rate in patients presenting to our ES was lower (44%) than the non-emergency condition rate.

CONCLUSIONS

Improvements in public education are needed to solve this problem. Also, Primary Care facilities should be improved in order to reduce the demand for medical attention in ES by non-urgent patients.

A new method for hepatic resection and hemostasis: absorbable plaque and suture

OBJECTIVE

Blunt and penetrating hepatic injuries are conditions that are frequently encountered in emergency surgeries, and they involve high mortality morbidity. In the handling of such injuries, methods ranging from the application of simple cauterization and suturing for hemostasis to hepatic lobectomies, which might involve the removal of the greater part of the organ, have been defined. Due to the organ's fragility and susceptibility to bleeding, elective hepatic resections necessitate both surgical experience and technological equipment. Therefore, the demand still exists for an affordable and easy-to-use-method that could be applied by all centers.

MATERIALS AND METHODS

To meet this demand, we have developed a method of hemorrhage control via sutures supported by absorbable plaques that provide effective compression and prevent the suture from cutting the tissue during the application of the sutures in the treatment of such fragile organs as the liver. In our method, we have achieved hemostasis by bilaterally compressing the tissue through strong ties after placing, on the part of the tissue on which the sutures are applied, absorbable and flexible plaques that prevent the suture from cutting the tissue during the application of a polyglactin suture to the solid organ. To prevent dislocation of the plaques, we have fastened the sutures by reeving them through the holes made in the plaques.

RESULTS

We have demonstrated the success and the practicality of our method by applying it on four pigs; we experimentally inflicted hepatic injuries on two pigs, and we performed resection on the other two pigs. The hepatic hemorrhages we developed in both of the animals were successfully restrained by the use of our method. On the other hand, two resections were performed on the right and left lobes of the other two animals. There were no hemorrhages during the surgery, and the procedure took 45 minutes in total. No postoperative complications occurred. While the liver function test values were high on the seventh day, due to the operation, they were observed to be normal on the thirtieth day. After the laparotomies, performed six months later, we observed that the plaques as well as the sutures were absorbed and that the injured tissues were completely healed. Additionally, it was observed during the pathological examination that the tissues beneath the area of application were healed through fibrosis and that the liver had no other pathologies.

CONCLUSIONS

In conclusion, we believe that the method can be safely used in hepatic resections or traumatic hemorrhages in the proper locations.

Use of self-expanding covered stent and negative pressure wound therapy to manage late rectal perforation after injury from an improvised explosive device: a case report

Blast injuries, caused by explosions accompanied by high-pressure waves, produce tissue damage in the acute period, followed in the later period by circulatory disorders due to vascular endothelial damage and related tissue necrosis. Blunt rectal perforation is rare and difficult to diagnose. In the acute period following blast pelvic injuries, the main objectives are to stop bleeding, minimise contamination and preserve the patient's life. The patient in this report had major vascular injuries, severe pelvic injury and, in the later period, rectal perforation because of vascular endothelial damage caused by the blast effect. Our aim was to treat the patient conservatively because of his poor general condition. We placed a self-expanding covered stent (SECS) into the rectum and then applied negative pressure wound therapy (NPWT; V.A.C.® Therapy, KCI) to the pelvic region and perirectal area. At the end of the treatment, the rectal perforation was closed, and the patient was discharged with healing. In this article, we discuss the novel use of an SECS with NPWT and review related literature.

A novel laparoscopic suction device for applying precise aspiration during laparoscopic surgery: sponge-tip suction tube

Aspiration of the intra-abdominal fluid and debris is usually needed during different stages of the operation. This is necessary to protect the intra-abdominal space from contamination and/or to remove blood or tissue fluids occurring during the operation. It is also essential for obtaining a clean surgical area. Aspiration of the intra-abdominal fluid is relatively more difficult in laparoscopic surgery because of the suctioning of the omentum and intestine with the aspirator. In this paper, we report on a new suction device (sponge tip suction tube; STST), which allows the surgeon easier suctioning of intra-abdominal fluid. STST has an additional sponge tip and air channel, which prevents the device from suctioning intra-abdominal organs, such as the intestine and omentum. We tested the efficacy of STST in a simulated intra-abdominal space, such as a large transparent plastic bag with fresh sheep intestine-omentum and with 2000 cc of physiologic saline solution and 14 mm Hg of air pressure. Whereas the suctioning of all the fluid was difficult and time consuming when the conventional suction unit was used, all of the saline solution was easily and quickly suctioned when STST was used. In conclusion, STST provides a safe, fast, and complete fluid extraction.
