RESUMEN

While the 'best pancreatic anastomosis technique' debate is going during Whipple procedure, the laparoscopic pancreaticoduodenectomy lately began to appear more and more often in the medical literature. All the popular anastomosis techniques used in open pancreas surgery are being experienced in laparoscopic pancreaticoduodenectomy. However, when they were adapted to laparoscopy, their implementation was not technically easy, and assistance of robotic surgery was sometimes required at the pancreatic anastomosis stage of the procedure. Feasibility and simplicity of a new technique have a vital role in its adaptation to laparoscopic surgery. We frequently use the extra-mucosal single row handsewn anastomosis method in open and laparoscopic surgery of the stomach, small and large bowel and we found it easy and reliable. Here, we defined the adaptation of this technique to the laparoscopic pancreas anastomosis. The outcomes were not inferior to the other previously described techniques and it has the advantage of simplicity.

RESUMEN

Cyclosporin A (CsA) is the most widely used immunosuppressive drug for preventing graft rejection and autoimmune disease. However, the therapeutic treatment induces several side effects such as nephrotoxicity, cardiotoxicity, hypertension, and hepatotoxicity. Curcumin has been successfully used as a potent antioxidant against many pathophysiological states. This experimental study was performed to test, during CsA treatment, the alterations of curcumin antioxidant properties against CsA-induced endothelial dysfunction. Rats were divided into four groups: control, curcumin alone, CsA, and CsA + curcumin; each group containing eight animals. The animals in the CsA + curcumin group were treated with CsA (10 days, 25 mg/kg, orally) and curcumin (15 days, 200 mg/kg, orally, starting 5 days before CsA administration). At the end of the treatments, the animals were killed; serum and aorta tissue were treated for biochemical and morphological analyses. The results indicate that CsA-induced aortic endothelial dysfunction was characterized by morphological and ultrastructural alterations in tissue architecture, changes in malondialdehyde and ferric reducing/antioxidant power levels, and increase in endothelial nitric oxide synthase and terminal-deoxynucleotidyl-transferase mediated dUTP nick end labeling (TUNEL) expression. In conclusion, our data suggest that the imbalance between production of free oxygen radicals and antioxidant defence systems, due to CsA administration, is a mechanism responsible for oxidative stress. Moreover, we show that curcumin plays a protective action against CsA-induced endothelial dysfunction and oxidative stress, as supported by biochemical, ultrastructural, immunohistochemical, and TUNEL results.

RESUMEN

OBJECTIVE: Thyroid pathologies and non-medullary thyroid cancer often accompany primary hyperparathyroidism (PHPT). The purpose of this study was to examine the association between thyroid diseases, especially micropapillary thyroid cancer, with PHPT. MATERIAL AND METHODS: Data regarding 46 patients who were operated on with a diagnosis of PHPT at Inonu University Faculty of Medicine, General Surgery Clinic between June 2009 and March 2013 were retrospectively analyzed. Age, gender, levels of preoperative calcium, parathyroid hormone and phosphorus, and the histopathological results of the removed parathyroid and thyroid tissues were evaluated. All of the patients had a preoperative diagnosis of PHPT and there was no history of radiation to the head and neck region in any of the patients. RESULTS: Out of the 46 patients who were operated on for PHPT, 39 were female and 7 were male. The mean age was 52.8 years (25-76). Simultaneous thyroidectomy was performed in 35 patients (76.1%) due to an accompanying thyroid disorder. Papillary microcarcinoma was detected in 5 of these 35 (10.9%) patients who underwent thyroidectomy, two of which (40%) were multifocal tumors. The benign thyroid pathologies detected in the remaining 30 (65.2%) cases included lymphocytic thyroiditis in 3, Hashimoto thyroiditis in 1, follicular adenoma in 3 (two of which was Hurtle cell), and nodular colloidal goiter in 23 patients. The preoperative serum phosphate level was significantly higher in the group with papillary thyroid microcarcinoma (p=0.013). CONCLUSION: In regions where goiter is endemic, thyroid diseases and thyroid papillary microcarcinoma occur in association with PHPT at a higher rate compared to the normal population. Therefore, we believe that patients who are planned for surgery due to PHPT should be thoroughly investigated for the presence of any concomitant malignant thyroid pathologies in the preoperative period. It should also be kept in mind that patients with high blood serum phosphate values may have an increased risk of papillary thyroid microcarcinoma.

RESUMEN

BACKGROUND: Mesenteric ischemia and reperfusion (I/R) syndrome (MIRS) has been considered a clinicopathologic entity associated with a variety of clinically severe conditions with decreased intestinal blood flow and has been known to induce I/R damage in various organs. Sirolimus (SRL), a macrolide antibiotic isolated from a strain of Streptomyces hygroscopicus, is a potent and nonnephrotoxic immunosuppressant. OBJECTIVE: This study was designed to investigate the potential impact of sirolimus on MIRS-induced I/R damage in renal, intestinal, pulmonary, and hepatic tissues in an experimental rat model. METHODS: Twenty-four male Sprague-Dawley rats, aged 6 to 8 weeks and weighing 280 (±20 g), were studied. Using computer-generated random numbers, rats were assigned to 1 of the following 3 groups: group 1 (I/R group, n = 8), group 2 (I/R + sirolimus group, n = 8), and group 3 (control group, n = 8). Sirolimus, in a 1 mg/mL (60 mL) solution, was administered intraperitoneally in a dose of 1.5 mg/kg/d to the rats assigned to group 2 starting from 3 days before the surgical procedure. In surgery, a laparotomy was performed to clamp the superior mesenteric artery and, thus, induce bowel ischemia in groups 1 and 2. After 60 minutes of ischemia, the microvascular clamp on the superior mesenteric artery was removed for 3 hours of reperfusion. Soon after experimental induction of MIRS, bowel, lung, kidney, and liver specimens from each animal were harvested for both biochemical and histopathologic analysis. RESULTS: There were statistically significant differences between groups 1 and 3 with regard to degrees of intestinal (P < 0.001), hepatic (P = 0.001), renal (P < 0.001), and pulmonary (P = 0.01) I/R damage. The lung specimens from group 2 had less inflammation and perivascular edema formation compared with specimens from group 1, but no statistical significance was observed between the groups (P < 0.33). There were statistically significant differences between groups 1 and 2 with regard to degrees of intestinal, hepatic, and renal I/R damage (P = 0.001 for all). CONCLUSION: The findings of the present study demonstrate the attenuating effects of sirolimus on I/R damage in the intestine and remote organs, including the liver and kidney in the setting of MIRS in an experimental rat model. As a therapeutic implication, the utility of sirolimus may be of clinical value in procedures associated with a high likelihood of I/R damage, including major abdominal operations and renal transplantation. However, whether these results apply to humans is unclear. Additional experimental and clinical studies are warranted to confirm the clinical utility of sirolimus in conditions potentially associated with I/R damage.

RESUMEN

INTRODUCTION: Laparoscopic Roux-en-Y gastric bypass (LRYGB) is one of the most preferred bariatric procedures in the world for surgical treatment of morbid obesity. The Harmonic scalpel (HS) and LigaSure (LS) are the most commonly used devices in laparoscopic surgery. As far as we know, there is no comparative study of the two energy devices in LRYGB for morbid obesity. AIM: To compare the intraoperative performances of the two energy devices in LRYGB for morbid obesity. MATERIAL AND METHODS: The HS and LS were used in 43 and 42 cases, respectively. The patient demographics of both groups were comparable. The duration of the procedures (gastric pouch creation time and total operation time), quantity of bleeding (during gastric pouch creation and total quantities of bleeding) and the number of pneumoperitoneum desufflations due to smoking that impaired sight fields were recorded prospectively. RESULTS: Gastric pouch creation time (HS: 22.5 ±9.5 vs. LS: 19.5 ±9.7 min, p = 0.15), bleeding during gastric pouch preparation (HS: 15.3 ±30.5 vs. LS: 17.5 ±31.3 ml, p = 0.74), total operation time (HS: 183.2 ±47 vs. LS: 165.3 ±37.1 min, p = 0.06) and total bleeding (HS: 110 ±195.5 vs. LS: 102.5 ±70 ml, p = 0.81) were similar in the two groups. Only the mean number of pneumoperitoneum desufflations due to smoking was lower in the HS group (HS: 0.28 ±0.49 vs. LS: 0.57 ±0.78, p = 0.04). CONCLUSIONS: The HS and LS performed similarly in LRYGB, with fewer desufflations from smoking in the HS group.

RESUMEN

The aim of this study was to demonstrate the feasibility of laparoscopic restorative proctocolectomy (LRPC) without additional abdominal incisions. Two sisters with familial adenomatous polyposis were enrolled. The colon and rectum were mobilized entirely through the five abdominal trocars. The terminal ileum and distal rectum were transected with endoscopic staplers. The entire colorectal specimen was extracted transanally. A circular stapler anvil was introduced transanally. The J-pouch was created intracorporeally. The rectal stump was re-closed and a pouch-anal anastomosis was created using a circular stapler. We used a transanal tube for decompression of the pouch instead of a diverting ileostomy. The patients were discharged on the 10(th) and 12(th) days uneventfully. Both were doing well with their pouches after 18.5 and 12.1 months of follow-up. With the help of transanal specimen extraction and transanal tube decompression, additional abdominal incisions can be avoided following LRPC.

RESUMEN

INTRODUCTION: Retroperitoneal masses presenting as an inguinal hernia are rare conditions. PRESENTATION OF CASE: A 53 year old male admitted with the symptoms of weight loss, abdominal discomfort and left sided recurrent inguinal hernia. Physical examination demonstrated an abdominal mass in the left flank and an irreducible, painless scrotal mass. He had a history of left sided inguinal hernia surgery six years ago. Computed tomography revealed a large enhancing left sided retroperitoneal mass invading the colon, pancreas and kidney and it was going down towards the left scrotum. Unblock tumor resection including the neighboring organs (left kidney, left colon, distal pancreas with spleen) was performed. Scrotal extension of the tumor was also excised and the inguinal canal was repaired primarily. Histopathology of the mass was myxoid-liposarcoma. The patient has disease free, without hernia recurrence but poor in renal function after twenty months follow-up. DISCUSSION: Large retroperitoneal tumors may grow towards the inguinal region and they can mimic an inguinal hernia. An irreducible, painless and hard scrotal mass should be considered from this perspective.

RESUMEN

INTRODUCTION: Spontaneous rupture of the biliary duct, a rare condition in adults, is difficult to diagnose preoperatively and presents with acute abdominal symptoms. The treatment of this rare condition should be based on the individual's clinical status. We present peripheric biliary duct rupture (segment three) treated with external segment III drainage and postoperative endoscopic removal of the stones. PRESENTATION OF CASE: An 82-year-old male patient presented with abdominal pain and fever. An ultrasound (US) revealed a solid gall stone lesion, 3cm in diameter, in liver segments three and four with additional intra-abdominal fluid accumulation without coexisting free air. A diagnostic laparotomy was then performed because the patient had signs of peritonitis. Exploration revealed a biliary leakage from the posterior surface of segment three. An external biliary drainage catheter was inserted to the perforated segment III duct via a 6 French (6F) feeding catheter. He was discharged after 10 days and his intracholedocal stent was removed postoperative after three months. The patient continues to be monitored. DISCUSSION: Spontaneous rupture of the intrahepatic biliary duct is a rare condition. Although occurrence is frequently reported as spontaneous, the majority of cases are related to choledocholithiasis. The role of surgical treatment in cases of spontaneous bile duct rupture is unclear. When biliary peritonitis is present, drainage of contaminated biliary fluid, T-tube drainage, closure of the biliary duct, as well as primary disease conditions, should be reviewed prior to treatment. CONCLUSION: Surgical treatment of spontaneous biliary duct rupture should be indicated only after careful consideration of the patient's clinical and comorbidity status.

RESUMEN

BACKGROUND Idiopathic noncirrhotic portal hypertension (INCPH) is a rare disease characterized by increased portal venous pressure in the absence of cirrhosis and other causes of liver diseases. The aim of the present study was to present our results in using portosystemic shunt surgery in patients with INCPH. MATERIAL AND METHODS Patients who had been referred to our Liver Transplantation Institute for liver transplantation and who had undergone surgery from January 2010 to December 2015 were retrospectively analyzed. Patients with INCPH who had undergone portosystemic shunt procedure were included in the study. Age, sex, symptoms and findings, type of portosystemic shunt, and postoperative complications were assessed. RESULTS A total of 1307 patients underwent liver transplantation from January 2010 to December 2015. Eleven patients with INCPH who did not require liver transplantation were successfully operated on with a portosystemic shunt procedure. The mean follow-up was 30.1±19 months (range 7-69 months). There was no mortality in the perioperative period or during the follow-up. Two patients underwent surgery again due to intra-abdominal hemorrhage; one had bleeding from the surgical site except the portacaval anastomosis and the other had bleeding from the h-graft anastomosis. No patient developed encephalopathy and no patient presented with esophageal variceal bleeding after portosystemic shunt surgery. Shunt thrombosis occurred in 1 patient (9.9%). Only 1 patient developed ascites, which was controlled medically. CONCLUSIONS Portosystemic shunt surgery is a safe and effective procedure for the treatment of patients with INCPH.

RESUMEN

We aimed to perform a more and more minimal invasive splenectomy by only through two 5 mm umbilical trocars and one vaginal trocar. A 43-year-old female (BMI 31 kg/m(2), ASA II) with immune thrombocytopenic purpura was planned for splenectomy. She had a history of a previous cesarean section for three times. Two 5 mm trocars were inserted separately through the umbilicus. We did not use any single port device or similar modifications. A 15 mm trocar was inserted through the posterior fornix of the vagina under umbilical laparoscopic vision. The 5 mm umbilical ports were used for camera and retraction of the spleen. The transvaginal port was used for dissection and division of the spleen by a 10-mm LigaSure Atlas vessel sealing system. No clips or staples were used. As the spleen became completely free in the abdomen, it was removed through the vagina in a bag without fragmentation. The operating time was 200 minutes and the blood loss was minimal (< 20 ml). No drain or abdominal fascia suturing was used but closing the posterior fornix of the vagina. Her postoperative course was uneventful and she was discharged on day two without complication. She did not require any analgesics postoperatively. Platelet values increased to 408.000 mm(3) in the follow-up. To the best of our knowledge, this report described the most minimal invasive splenectomy even. Additionally, it provided an unfragmented spleen extraction. The transvaginal approach seems to be a feasible way to perform natural orifice splenectomy.

RESUMEN

PURPOSE: Natural orifice specimen extraction (NOSE) is an ever-evolving advanced laparoscopic technique. NOSE minimizes surgical injury, involving a low risk of wound complications, fewer incisional hernias, faster recovery and less postoperative pain. Laparoscopic gastrectomy combined with NOSE is a procedure that can potentiate the advantages of both minimal invasive techniques. We aim to demonstrate the feasibility of laparoscopic subtotal gastrectomy with transvaginal specimen extraction in advanced gastric cancer. CASE: A 72-year-old woman with a 2cm adenocarcinoma in gastric antrum was treated by laparoscopic subtotal gastrectomy and lymph node dissection. A totally laparoscopic Roux-en-Y gastrojejunostomy was constructed. Specimen was extracted through the posterior fornix of vagina without difficulty. Histopathology confirmed pT3pN0 tumor. After a 10-month follow-up the patient was asymptomatic and getting adjuvant chemoradiotherapy. CONCLUSIONS: Transvaginal specimen extraction after laparoscopic gastric resection for advanced gastric cancer is a feasible procedure. It is offered to selected patients and of course only to female patients. Natural orifice surgery may provide faster recovery and decrease the wound related complications which may cause a delay on postoperative adjuvant chemo-radio therapies. We have presented, as far as we know, the first human case of a transvaginal extraction of an advanced gastric cancer after laparoscopic gastrectomy.

RESUMEN

AIM: To study the transcolonic extraction of the proximally resected colonic specimens by colonoscopic assistance at laparoscopic colonic surgery. METHODS: The diagnoses of our patients were Crohn's disease, carcinoid of appendix and adenocarcinoma of cecum. We preferred laparoscopic total mesocolic resections. Colon and terminal ileum were divided with endoscopic staplers. A colonoscope was placed per anal and moved proximally in the colon till to reach the colonic closed end under the laparoscopic guidance. The stump of the colon was opened with laparoscopic scissors. A snare of colonoscope was released and the intraperitoneal complete free colonic specimen was grasped. Specimen was moved in to the colon with the help of the laparoscopic graspers and pulled gently through the large bowel and extracted through the anus. The open end of the colon was closed again and the ileal limb and the colon were anastomosed intracorporeally with a 60-mm laparoscopic stapler. The common enterotomy orifice was closed in two layers with a running intracorporeal suture. RESULTS: There were three patients with laparoscopic right-sided colonic resections and their specimens were intended to remove through the remnant colon by colonoscopy but the procedure failed in one patient (adenocarcinoma) due to a bulky mass and the specimen extraction was converted to transvaginal route. All the patients had prior abdominal surgeries and had related adhesions. The operating times were 210, 300 and 500 min. The lengths of the specimens were 13, 17 and 27 cm. In our cases, there were no superficial or deep surgical site infections or any other complications. The patients were discharged uneventfully within 4-5 d and they were asymptomatic after a mean 7.6 mo follow-up (ranged 4-12). As far as we know, there were only 12 cases reported yet on transcolonic extraction of the proximal colonic specimens by colonoscopic assistance after laparoscopic resections. With our cases, success rate of the overall experience in the literature was 80% (12/15) in selected cases. CONCLUSION: Transcolonic specimen extraction for right-sided colonic resection is feasible in selected patients. Both natural orifice surgery and intracorporeal anastomosis avoids mini-laparotomy for specimen extraction or anastomosis.

RESUMEN

BACKGROUND: The length of incisions on the abdominal wall directly correlates with wound-related morbidities and patient comfort. Both mini-laparoscopy (only ≤5-mm trocars) and natural orifice specimen extraction avoid larger abdominal incisions. This study described a new natural orifice translumenal endoscopic surgery (NOTES(®); American Society for Gastrointestinal Endoscopy [Oak Brook, IL] and Society of American Gastrointestinal and Endoscopic Surgeons [Los Angeles, CA]) cholecystectomy technique by combination of these two advanced laparoscopic techniques for cholelithiasis in patients who had prior laparoscopic Roux-en-Y gastric bypass (LRYGB) for obesity. PATIENTS AND METHODS: Three patients (two males, one female; 39, 62, and 34 years old, respectively) were admitted with symptomatic cholelithiasis (multiple millimeter-sized gallstones), and all had previously had LRYGB. They were treated by mini-laparoscopic cholecystectomy using three 5-mm trocars. The gallbladder was removed through the dilated efferent limb of the jejunum, 5 cm distal from the gastrojejunostomy. Transjejunal extraction was performed under endoscopic guidance. The gallbladder in the jejenum was passed through the anastomosis and extracted with an endoscopic snare by the transoral way. The enterotomy was closed intracorporeally. RESULTS: There was no conversion or additional trocar requirement. All the procedures were completed successfully without problems. Respective operating times were 95, 75, and 120 minutes. Only 1 patient required postoperative analgesic; the others did not. The patients started to get a liquid diet on the night of surgery and were discharged on Days 1, 1, and 2, respectively, with normal diet recommendations. There were no morbidities. CONCLUSIONS: Mini-laparoscopic cholecystectomy is technically feasible in patients with previous LRYGB. Prior LRYGB was not an obstacle for transoral specimen extraction. The dilated efferent jejunal limb is a good alternative route for natural orifice specimen extraction. This report described the first natural orifice surgery through the small bowel.

RESUMEN

The majority of swallowed foreign bodies are thrown spontaneously without causing complications in the digestive system. Multiple number of foreign bodies may be swallowed by psychiatric patients which delay diagnosis and increase the complication rate. Long and hard objects cannot pass through the pylorus, and may cause obstruction, ulceration, bleeding and perforation. Endoscopy is used as an effective method in such cases. An exploratory laparatomy was performed after unsuccessful endoscopic foreign object removal in a 28-year-old schizophrenic patient with gastric outlet obstruction due to multiple cigarette lighter swallowing. Ten lighters were removed from the stomach through gastrotomy and one more lighter was removed from the descending colon by milking through the anus. The aim of this paper is to discuss encountered difficulties in psychiatric patients who underwent surgery due to intake of foreign bodies.

RESUMEN

BACKGROUND: We aimed to compare the direct trocar insertion (DTI) and Veress needle insertion (VNI) techniques in laparoscopic bariatric surgery. MATERIALS AND METHODS: Eighty-one patients scheduled for bariatric surgery at Inonu University, Malatya, Turkey, were included in this study. In 39 patients, a bladed retractable nonoptical trocar was used for DTI, and VNI was performed in 42 patients. Intraoperative access-related parameters were compared. Data were analyzed with Student's t and chi-squared tests. A P value of <.05 was considered significant. RESULTS: Both groups had comparable demographic profiles. Laparoscopic entry time was shorter in the DTI group (79.6 ± 94.6 versus 217.6 ± 111.0 seconds; P < .0001). Successful entry rates in the first attempt, CO2 consumptions, failed attempt rates, and overall intraoperative complication rates were similar. However, in the DTI group, 2 patients had mesenteric injuries, and 1 of them required conversion to open surgery due to the mesenteric hemorrhage. CONCLUSIONS: DTI in obese patients significantly shortens the entry time, but there can be severe complications with DTI when a nonoptical bladed trocar is used blindly. Actually, neither method can be recommended for entry into the abdomen in this population based on our results. If the surgeon has to choose a nonoptical trocar in bariatric surgery, preference for the VNI technique instead of the DTI technique is safer.

RESUMEN

INTRODUCTION: Endoscopic esophageal stent placement is used to treat benign strictures, esophageal perforations, fistulas and for palliative therapy of esophageal cancer. Although stent placement is safe and effective method, complications are increasing the morbidity and mortality rate. We aimed to present a patient with small bowel perforation as a consequence of migrated esophageal stent. PRESENTATION OF CASE: A 77-years-old woman was admitted with complaints of abdominal pain, abdominal distension, and vomiting for two days. Her past medical history included a pancreaticoduodenectomy for pancreatic tumor 11 years ago, a partial esophagectomy for distal esophageal cancer 6 months ago and an esophageal stent placement for esophageal anastomotic stricture 2 months ago. On abdominal examination, there was generalized tenderness with rebound. Computed tomography showed the stent had migrated. Laparotomy revealed a perforation localized in the ileum due to the migrated esophageal stent. About 5cm perforated part of gut resected and anastomosis was done. The patient was exitus fifty-five days after operation due to sepsis. DISCUSSION: Small bowel perforation is a rare but serious complication of esophageal stent migration. Resection of the esophagogastric junction facilitates the migration of the stent. The lumen of stent is often allow to the passage in the gut, so it is troublesome to find out the dislocation in an early period to avoid undesired results. In our case, resection of the esophagogastric junction was facilitated the migration of the stent and late onset of the symptoms delayed the diagnosis. CONCLUSION: Patients with esophageal stent have to follow up frequently to preclude delayed complications. Additional technical procedures are needed for the prevention of stent migration.

RESUMEN

Background. Natural orifice transluminal endoscopic surgery (NOTES) is a new approach that allows minimal invasive surgery through the mouth, anus, or vagina. Objective. To summarize the recent clinical appraisal, feasibility, complications, and limitations of transvaginal appendectomy for humans and outline the techniques. Data Sources. PubMed/MEDLINE, Cochrane, Google-Scholar, EBSCO, clinicaltrials.gov and congress abstracts, were searched. Study Selection. All related reports were included, irrespective of age, region, race, obesity, comorbidities or history of previous surgery. No restrictions were made in terms of language, country or journal. Main Outcome Measures. Patient selection criteria, surgical techniques, and results. Results. There were total 112 transvaginal appendectomies. All the selected patients had uncomplicated appendicitis and there were no morbidly obese patients. There was no standard surgical technique for transvaginal appendectomy. Mean operating time was 53.3 minutes (25-130 minutes). Conversion and complication rates were 3.6% and 8.2%, respectively. Mean length of hospital stay was 1.9 days. Limitations. There are a limited number of comparative studies and an absence of randomized studies. Conclusions. For now, nonmorbidly obese females with noncomplicated appendicitis can be a candidate for transvaginal appendectomy. It may decrease postoperative pain and enable the return to normal life and work off time. More comparative studies including subgroups are necessary.

RESUMEN

AIM: Natural orifice translumenal endoscopic surgery (NOTES(®); American Society for Gastrointestinal Endoscopy [Oak Brook, IL] and Society of American Gastrointestinal and Endoscopic Surgeons [Los Angeles, CA]) is a new approach that allows surgical manipulations and specimen extractions through the natural orifices such as the vagina. There have been limited numbers of cases about the adaptation of NOTES for ventral hernia repairs. Here, we aimed to present two more cases and highlight our technical differences compared with the previously reported instances. PATIENTS AND METHODS: Two patients (43 and 46 years old; body mass index of 29 and 30 kg/m(2), respectively) were treated with hybrid transvaginal incisional hernia repairs. Two 5-mm abdominal trocars were used to monitor transvaginal access, adhesiolysis, dissection of the hernia, and tuckering of the mesh. A 15-mm transvaginal trocar was used for scope and mesh introduction into the abdomen. Defects were 3-5 cm in diameter. RESULTS: A rigid 5-mm laparoscope was used. The composite synthetic meshes were, respectively, 11 and 13 cm in diameter. These were passed through the vagina without any protection such as a bag or sheath. No conversion or additional port was required. Respective operative times were 120 and 180 minutes, and the patients were discharged uneventfully on the second day. One patient had seroma, which was managed conservatively (aspiration of 20 mL on Day 7). There were no recurrences after 7 and 13 months, respectively. CONCLUSIONS: Conventional laparoscopic equipment can be used for hybrid transvaginal incisional hernia repair. An anti-adhesive synthetic mesh can be inserted through the vaginal trocar without protective devices. The main advantage of this technique is to avoid 10-15-mm abdominal trocars, which increase the risk of trocar-site hernias themselves.
