The influence of platelet-rich plasma (PRP) on colonic anastomosis healing impaired by intraperitoneal 5-flourouracil application. An experimental study

Purpose

5-flourourasil (5-FU) is commonly used for early intraperitoneal chemotherapy in colorectal or appendiceal cancer patients with peritoneal carcinomatosis. Due to its effect, anastomosis healing can be impaired and leads to anastomotic leakage. In this study, we aimed to investigate the potential healing effect of platelet-rich plasma (PRP) on colonic anastomosis impaired by intraperitoneal 5-flourouracil application.

Methods

After ten rats were sacrificed for preparing PRP, forty Wistar-albino rats were subjected to colonic anastomosis, and randomly allocated into four groups including 10 rats each. According to receiving PRP and/or 5-FU application, the groups were formed as control (C), 5-FU without PRP (CT), anastomosis with PRP (C-PRP), and 5-FU with PRP (CT-PRP). CT and CT-PRP groups also received 5-FU intraperitoneally on postoperative day 1 (POD 1). All animals were euthanized on pod 7. The body weight change, anastomotic bursting pressure (ABP), tissue hydroxiprolin (TH) and histopathological examination of each group were analyzed.

Results

5-FU application significantly reduced ABP levels when compared with group C, C-PRP and CT-PRP (for each comparison, p<0,01). PRP application in CT-PRP group raised the measure of ABP up to the levels of C group. Although tissue hydroxyproline levels (THL) levels of CT-PRP group were found higher than CT group, it was not significant (p=0.112). Microscopically, comparing with CT group, PRP application significantly promoted the healing of colonic anastomosis subjected to 5-FU application by improving tissue edema, necrosis, submucosal bridging and collagen formation (p<0.05). Tissue healing in CT-PRP group was observed as good as the control groups. (C, C-PRP, p=0.181, p=0.134; respectively).

Conclusion

PRP administration on colonic anastomosis significantly promotes the healing process of anastomosis in rats receiving 5-FU. This result encourages further clinical use of PRP to reduce the frequency of AL in patients receiving EPIC.

A Giant Aggressive Angiomyxoma of the Pelvis Misdiagnosed as Incarcerated Femoral Hernia: A Case Report and Review of the Literature

Aggressive angiomyxoma (AA) is an uncommon mesenchymal tumor that is mostly derived from the female pelvic and perineal regions. AA is a locally infiltrative slow growing tumor with a marked tendency to local recurrence. Painless swelling located around the genitofemoral region is the common symptom; thus, it is often misdiagnosed as a gynecological malignancy or a groin hernia. A 35-year-old female patient who previously underwent surgery for left femoral hernia operation resulting in surgical failure was reoperated for a giant AA located in the pelvis. The tumor was completely excised with free margins. Histopathologic examination revealed an AA. The tumor size was measured as 24 × 12 × 6 cm with a weight of 4.2 kg. Immunohistochemically, the cells show positive staining with vimentin, desmin, estrogen, and progesterone receptor. S100, MUC4, CD34, and SMA were negative in the tumor cells. AA should be considered in the differential diagnosis of any painless swelling located in the genitofemoral region, particularly in women of reproductive age. The principle treatment should be complete surgical excision with tumor-free margins. Long-term follow-up and careful monitoring are essential due to its high tendency of local recurrence in spite of wide excision of the tumor. Adjuvant antihormonal therapy yields promising results for preventing recurrence.

Intra-abdominal Gossypiboma Revisited: Various Clinical Presentations and Treatments of this Potential Complication

Gossypiboma is the term used to describe a retained non-absorbable surgical material that is composed of cotton matrix which leads to serious surgical complications for both patient and surgeon. Its incidence is not precisely known probably due to medico-legal importance of this potential complication. The condition may manifest either as asymptomatic or severe gastrointestinal complications. The increasing number of recent reports in the literature implies that this issue still remains as an important problem to be solved after intra-abdominal surgery. In this report, we aimed to emphasize this potential complication by presenting the clinical outcomes of our 14 patients who underwent different surgical interventions for gossypiboma. Between February 2009 and October 2014, a total of 14 patients who underwent surgery for gossypiboma were reviewed retrospectively. The patients were analyzed with regard to demographic characteristics, initial diagnosis-prior surgery, clinical presentation, the interval period from the first operation to last definite operation, diagnostic methods, gossypiboma location, definite surgery, and postoperative outcomes. A total of 14 patients including 6 (42.9 %) male and 8 (57.1 %) female with a median age of 41.4 ± 12 years (22-61 years) enrolled in this study. The prior surgery of 10 (71.4 %) patients was performed by general surgeons, while 4 (28.6 %) patients were operated by gynecologists. The interval period from prior surgery to definite surgery ranged from 14 days to 113 months. Three (21.4 %) patients were asymptomatic, whereas the vast of the patients were complicated (fistula, ileus, wound infection). Gossypiboma was removed by open surgery, laparoscopic surgery, and endoscopic intervention in 10, 2, and 1 patient, respectively. Removal was performed from perineal wound side in one patient. Removal was enough for definitive treatment in 10 (71.4 %) patients whereas bowel resection and primary repair was performed in 4 (28.6 %) patients due to fistula or perforation. One patient died from intra-abdominal sepsis on postoperative 13th day. Gossypiboma should strongly be considered in differential diagnosis of any postoperative patient with mild gastrointestinal symptom or with persistent wound infection. Adequate surgical intervention should be planned as soon as possible either to prevent further complications or to overcome medico-legal problems, when gossypiboma is detected.

Ligation under vision in the management of symptomatic hemorrhoids: A preliminary experience

AIM

To evaluate the surgical outcomes of 47 patients who underwent hemorrhoidal arterial ligation under vision (LUV) for symptomatic Grade II and Grade III hemorrhoids.

METHODS

A total of 47 patients who underwent LUV between May 2005 and February 2009 were analyzed retrospectively. The patients were evaluated with regard to demographic data, grade of the disease, symptoms, medical and/or surgical treatment previously received, operation time, pain scores, analgesic requirement, length of hospital stay, and complications related to the procedure.

RESULTS

The study population (n = 47) included 31 (65.9%) men and 16 (34.1%) women with a median age of 37.4 ± 11.7 (range, 19-63) years. Of these 47 patients, 18 (38.3%) patients had Grade II hemorrhoidal disease (HD) and 29 (61.7%) patients had Grade III HD. On average, six ligatures (range, 3-8) were used. The mean operation time was 27 ± 4.8 (range, 15-35) minutes. No major complication that required surgical intervention occurred in the early postoperative period for any of the patients except for two patients with rectal submucosal hematoma. The mean hospital stay was 1.2 ± 0.65 (range, 1-4) days. The median follow-up period was 21.5 ± 7.7 (range, 12-44) months. At the last follow-up, 38 (80.8%) patients remained asymptomatic; two (4.2%) patients with Grade II HD and four (8.5%) patients with Grade III HD were still suffering from bleeding but with a reduction in the frequency; prolapsed hemorrhoids were detected only in three (6.3%) patients.

CONCLUSION

LUV is a safe and easily applied alternative technique with low postoperative complications for the surgical treatment of symptomatic Grade II and III HD.

Transgastric migration of gossypiboma remedied with endoscopic removal: a case report

Background

Retained surgical instrument or sponge following an intra-abdominal surgery is a potentially dangerous medico-legal problem. The condition may manifest either as asymptomatic or severe gastrointestinal complications. Transmural migration of gossypiboma is a rare entity that may lead to bowel or visceral perforation, obstruction and/or fistula formation. Transmural migration of an intra-abdominal gossypiboma has been reported to occur in stomach, ileum, colon, bladder, vagina and diaphragm. To our knowledge, this is the fifth case reported in the medical literature. However, we report the first case of the largest gossypiboma to date: a surgical gas compress measuring 20 × 20 cm which was successfully treated endoscopically.

Case presentation

A 52-year-old woman with obstructive jaundice was referred to our clinic. She had a medical history of cholecystectomy and T-tube drainage for choledocholithiasis a year previously. Abdominal ultrasonography and computed tomography revealed a mass located into the stomach which was compatible with gastric carcinoma. On the gastroscopy, a surgical gas compress that had totally migrated into the stomach was observed. The compress was successfully removed by gastroscopy through the esophagus. The recovery of the patient was uneventful.

Conclusion

Transmural migration of gossypiboma into the stomach should be considered in the differential diagnosis of any postoperative patient with obstructive jaundice symptoms. Endoscopy may be feasible for both diagnosis and treatment even though the size of gossypiboma is large. However, surgery should be considered in case of fixed reaction or incomplete migration of gossypiboma located into the stomach.

A prospective randomized comparison of single-port laparoscopic procedure with open and standard 3-port laparoscopic procedures in the treatment of acute appendicitis

BACKGROUND

This prospective randomized study aimed to evaluate the surgical outcomes of single-incision laparoscopic appendectomy (SILA) comparing with open appendectomy (OA) and standard 3-port laparoscopic appendectomy (SLA) in the treatment of acute appendicitis (AA).

METHODS

Adult patients older than 18 years presenting with AA were randomized into 3 groups to undergo OA, SLA, and SILA from September 2010 to May 2011. The groups were compared with regard of patient's characteristics, perioperative findings/complications, operative time, pain severity, analgesic requirement, time to oral tolerance and flatus, length of hospital stay, and cosmetic results.

RESULTS

A total of 75 consecutive patients enrolled in the study. Each group included 25 patients. The groups showed no significant differences in patient's characteristics. The mean operative time was significantly longer in SILA than OA with a mean difference of 7 minutes (P < 0.05). Postoperative pain after OA were significantly higher than SLA and SILA (P < 0.05). The average time to oral tolerance and flatus was significantly higher in OA than the laparoscopic groups with a mean difference of 1 and 2.5 hours (P = 0.04 and 0.023, respectively). The length of hospital stay in SLA and SILA was significantly lower than OA with a mean difference of 0.8 days (P < 0.05). There was no difference in overall complications between the groups. There was no difference between SLA and SILA in terms of surgical outcomes.

CONCLUSIONS

Either SLA or SILA offer patients faster recovery period with acceptable complications than OA. Hence, laparoscopic approach might be considered as first option in the treatment of AA. However, all 3 techniques provide equivalent clinical outcomes despite the significant findings. Therefore, technique selection is based on surgeon's decision, experience, and availability of laparoscopic instruments.

Comparison of standard 4-row versus 6-row3-D linear cutter stapler in creation of gastrointestinal system anastomoses: a prospective randomized trial

OBJECTIVE

This prospective study was conducted to compare the clinical outcomes of a 6-row 3-D linear cutter with the standard 4-row linear cutter in patients who underwent elective gastrointestinal surgery anastomosis.

METHOD

Patients who underwent elective open gastrointestinal surgery that included stapled anastomosis using a linear cutter (Proximate®, Ethicon Endo-Surgery, Cincinnati, OH) between January 2011 and May 2011 were included in the study. The patients were randomly assigned to two groups according to the linear cutter that was used in the surgery: the standard 4-row cutter (the S group) or the new 6-row cutter (the N group). The groups were compared based on the patient demographic data, the laboratory parameters, the preoperative diagnosis, the surgery performed, the operation time, intra-or postoperative complications, the time to oral tolerance and the length of the hospital stay.

RESULTS

The S group included 11 male and nine female patients with a mean age of 65 ± 12 (35-84) years, while the N group included 13 male and eight female patients with a mean age of 62 ± 11 (46-79) years (p =0.448, p = 0.443, respectively). Anastomotic line bleeding was observed in eight (40%) patients in the S group and in one (4.7%) patient in the N group (p = 0.006). Dehiscence of the anastomosis line was observed in two (10%) patients in the S group and none in the N group (p =0.131). Anastomotic leakage developed in three (15%) patients in the S group and in one (4.7%) patient in the N group (p = 0.269). The mean hospital stay was 12.65 ± 6.1 days in theS group and 9.52 ± 2.9 days in the N group (p = 0.043).

CONCLUSION

The 6-row 3-D linear cutter is a safe and easily applied instrument that can be used to create anastomoses in gastrointestinal surgery. The new stapler provides some usage benefits and is also superior to the standard linear cutter with regard to anastomotic line bleeding.
