Emergency transvaginal hybrid natural orifice transluminal endoscopic surgery

In a clinical series, 10 consecutive female patients with intra-abdominal infections were successfully treated with natural orifice transluminal endoscopic surgery (NOTES) performed transvaginally. The surgery, which consisted of a hybrid NOTES procedure using a transvaginal approach, was performed on an emergency basis by the surgical team on call. The indications for surgery were acute cholecystitis (n = 6), acute appendicitis (n = 2), and pelvic peritonitis (n = 2) with intra-abdominal infection. The procedure was successfully performed in all patients using a dual-channel endoscope and mini-laparoscopy assistance. This is the first clinical series in which NOTES has been performed on an emergency basis to treat intra-abdominal infections. Transvaginal surgery for intra-abdominal infection is a feasible procedure for groups experienced in the elective NOTES approach.

Transvaginal liver resection (NOTES) combined with minilaparoscopy

OBJECTIVE

to report on the first liver resection performed on a human being by a transvaginal NOTES approach combined with minilaparoscopy.

PATIENTS AND METHODS

a sixty-one-year-old woman with a history of Wertheim s hysterectomy for endometrial carcinoma 10 years ago, and malignant melanoma correctly treated in 2006, had suspected segment-V liver metastasis near the gallbladder by CT-scan and MRI. The indication for a laparoscopic approach was made, and a combined transvaginal and minilaparoscopic resection was offered and accepted by the patient. The procedure was performed by a multidisciplinary team composed of surgeons and gastroenterologists. It involved creating a pneumoperitoneum by placing a Veres needle in the umbilical fundus, followed by the insertion of a 5-mm trocar. A second, 3-mm trocar was placed in the right upper quadrant. A lot of pelvic adhesions were found in the major pelvis, and it was necessary to place a third, 5-mm trocar in the left abdominal side. It was employed only for the adhesions, not for liver resection. Adhesions were removed to reveal the minor pelvis and the vaginal fornix. A colpotomy was performed with a 12-mm trocar placed inside the vagina, which allowed the insertion of the videogastroscope as far as the liver hilum.

RESULTS

liver resection (segment-V partial resection) and cholecystectomy were performed by using a combination of working tools inserted through the entry port for the minilaparoscopy and the videogastroscope. The en bloc resection was removed transvaginally through the videogastroscope. There were no postoperative complications, and the patient was discharged after 48 hours.

CONCLUSIONS

transvaginal liver resection is possible and safe when performed by a multidisciplinary team. Natural orifice transluminal endoscopic surgery (NOTES) is an emerging modality that seeks to be less invasive, better tolerated, and more respectful of esthetics. It will probably open the way for very important medical and technological innovations.

[Minimally invasive surgery of the inguinal hernia]

The minimally invasive approach to the inguinal hernia shows advantages with respect to previous conventional approaches in bilateral and recurrent inguinal hernias; while the initial results were bad, new problems were added deriving from the laparoscopic approach. The aim of this article is to describe the surgical technique and analyse the preliminary results of our series of 600 totally extra-peritoneal hernioplasties, performed at the University Clinic of Navarra. The most frequent complication (25.7%) was the accidental rupture of the peritonea. There were no associated intra-abdominal complications. In the follow-up there were 9 relapses (1.5%) and 13 reinterventions. Eleven (1.8%) of the patients developed transitory neuropathic pain in the femoral cutaneous area. In our experience the totally extra-peritoneal approach is a technique that is especially indicated in relapsed and bilateral hernias. The advantages present, in terms of pain and postoperative discomfort, recovery of physical and labour activity, and the good results with respect to relapses and neuropathic pains, encourage us to indicate it not only in relapsed or bilateral inguinal hernias but also in primary ones.

The role of transjugular intrahepatic portosystemic shunt prior to abdominal tumoral surgery in cirrhotic patients with portal hypertension

INTRODUCTION

Major abdominal surgery can be contraindicated in some cirrhotic patients because of severe portal hypertension. The present study reports our experience of three patients with abdominal tumours prepared for surgery by transjugular intrahepatic portosystemic shunts (TIPS) in order to reduce portal hypertension and the risk of intraoperative bleeding.

PATIENTS AND METHODS

Three patients with cirrhosis and portal hypertension diagnosed with a right colon carcinoma, an adenocarcinoma of pancreas and a gastric and sigmoid synchronic tumours in the same patient. Because portal hypertension was the leading cause of surgical contraindication, neoadjuvant TIPS placement was proposed before surgery.

RESULTS

TIPS placement was performed without intra-procedure complications. An average reduction of 18 mmHg was achieved in portosystemic gradients. The planned operations were performed with a delay of 14-45 days after TIPS without intraoperative bleeding. Complications occurred in one patient without operative mortality.

CONCLUSION

TIPS placement allows a pre-operative portal decompression in cirrhotic patients with portal hypertension and abdominal tumours that require surgical treatment. This procedure reduces the risk of bleeding by reducing the portosystemic gradient and the varices around the tumoral area. This procedure is less invasive than conventional shunt surgery, but it is not free of complications and should be performed by experienced interventional radiologists on selected patients. This is still an experimental indication of TIPS which efficacy must be confirmed in larger series.

[Role of surgery in the treatment of primary gastric lymphoma]

Primary gastric lymphoma's optimum management remains controversial. We reviewed our series of 23 patients with primary gastric lymphoma treated in our hospital between 1976 and 1998 with surgery as main therapy. Ten patients underwent surgical resection alone, whereas 13 also received postoperative adjuvant therapy, depending on the oncologist-haematologist's recommendations. No differences were found between treatments regarding mortality and morbidity. Clinical-histological features and patients, follow-up are analyzed. No patient died because of lymphoma and there wasn't either local or distant recurrence. We consider that surgery remains a valid option for the primary gastric lymphoma treatment. The introduction of combined modalities of radiation therapy and chemotherapy will depend on the final stage, the tumor histological features, and the feasibility of getting a radical resection.
