A simple, effective technique for port-site closure after laparoscopy

Background and Objectives:

Fascial closure of port sites represents a challenging issue in laparoscopic surgery. The aim of this article is to introduce a procedure that allows the safe suturing of the abdominal fascia in these wounds.

Methods:

We herein describe a simple technique for fascial closure after laparoscopy using a transcutaneous approach and standard surgical instruments for suture.

Results:

The method was used in 34 patients with no intraoperative incidents and no port-site hernias during a mean follow-up of 23.9 months (median 20.5, range 5 to 47).

Conclusion:

The procedure is easy to perform, safe, fast, and inexpensive.     

Triple coronary artery revascularization on the stabilized beating heart: initial experience

Objective

To decrease health costs and morbidity related to extracorporeal circulation, surgeons have modified the coronary artery bypass (CAB) technique so that it can be completed without the use of extra-corporeal circulation. This study summarizes initial experience with direct coronary artery revascularization on the beating heart using a coronary stabilizer.

Design

A case series.

Setting

The Montreal Heart Institute, a university-affiliated centre, specializing in the treatment of cardiac illnesses.

Patients

Ten patients underwent CAB by this technique. They presented with double or triple coronary artery disease with no intramyocardial, heavily calcified, diffused atheromatous coronary vessels, or left main coronary disease.

Intervention

CAB grafting in the beating heart. The anterior wall was grafted in all patients, the inferior wall in 7 and the posterior wall in 7.

Main outcome measures

Patient survival and graft patency.

Results

One patient died of multiple organ failure not related to the grafting technique itself, and 1 patient suffered a non-Q myocardial infarction. Early coronary angiography performed on 8 patients showed 100% graft patency, most with excellent distal runoff (21/22 grafts).

Conclusion

In patients with adequate anatomy, performance of CAB without extracorporeal circulation can achieve excellent early results provided there is appropriate mechanical stabilization of the beating heart.     

SIMPLIFIED LAPAROSCOPIC CHOLECYSTECTOMY WITH TWO INCISIONS

Background

Laparoscopic cholecystectomy has traditionally been performed with four incisions to insert four trocars, in a simple, efficient and safe way.

Aim

To describe a simplified technique of laparoscopic cholecystectomy with two incisions, using basic conventional instrumental.

Technique

In one incision in the umbilicus are applied two trocars and in epigastrium one more. The use of two trocars on the same incision, working in "x" does not hinder the procedure and does not require special instruments.

Conclusion

Simplified laparoscopic cholecystectomy with two incisions is feasible and easy to perform, allowing to operate with ergonomy and safety, with good cosmetic result.     

Port-Site Closure Using a Modified Aptos Needle

Background and Objectives:

Trocar-site incisional hernias are the most common complications in laparoscopic surgery. Fascial closure of port sites represents a challenging issue in laparoscopic surgery.

Methods:

We describe a simple easy technique for fascial closure of port sites using a double-tip needle (Lasheen needle). This study included 100 patients who underwent laparoscopic surgery from January 2009 through August 2011 in the General Surgery Department, Zagazig University Hospital, Zagazig, Egypt. The mean follow-up period was 2 years for any wound complications at these trocar sites.

Results:

The mean age of the patients was 39.5 years, and the mean time for placement of one suture was 2 minutes. No trocar-site herniation occurred with our technique during the period of follow-up. Infection developed at the trocar site in 3 patients.

Conclusion:

This technique is easy, simple, safe, fast, inexpensive, and effective for fascial closure of trocar sites.     

Ileosigmoid knotting in patients under 25 years of age: A report of two cases

INTRODUCTION

Ileosigmoid knotting is a rare cause of acute abdomen with high morbidity and mortality. Its diagnosis is infrequently made before surgery because of its varying ways of presentation and rarity.

PRESENTATION OF CASE

The first was a 21-year-old male who presented with a history of sudden generalized abdominal pain and progressive abdominal distension. He was pale and severely dehydrated. His extremities were cold and clammy. His pulse rate was 110 per minute and blood pressure was 90/50 mmHg.The second case was 20-year-old male who presented with similar symptoms as above. He was not pale but mildly dehydrated. His pulse rate was 92 per minute and blood pressure 110/70 mmHg.Both patients were resuscitated and had exploratory laparotomy a few hours after presentation. The first patient was found to have ileosigmoid knotting with gangrenous sigmoid colon and terminal ileum. He had Hartmann''s procedure and right hemicolectomy with ileo-transverse anastomosis.The second patient was found to have ileosigmoid knotting with viable loops of bowel. He had careful detorsion, sigmoidectomy with primary anastomosis. Both patients’ have good outcome.

DISCUSSION

This is to report two cases of ileosigmoid knotting in two male patients aged 21 and 20 years, respectively, with the hope of increasing awareness.

CONCLUSION

Ileosigmoid knotting though more common in fourth or fifth decade of life, can also occur in the 2nd decade. Early diagnosis, careful resuscitation and skilful surgical intervention will improve outcome.     

Laparoscopic Repair of Abdominal Hernias Using an ePTFE Patch��A Modification of a Previously Described Technique

Background:

A variety of laparoscopic procedures for the repair of abdominal wall hernias have been described. The repair described in this paper represents a modification and improvement of one approach.

Methods:

Our technique employs an Origin Tacker (Origin Medsystems, Inc, Menlo Park, CA) and a Gore suture passer (W. L. Gore, Flagstaff, AZ) to secure an expanded polytetrafluoroethylene (ePTFE) patch, (DualMesh, W. L. Gore, Flagstaff, AZ) to the anterior abdominal wall.

Results:

This approach simplifies the repair by minimizing the number of steps required to secure the ePTFE graft to the anterior abdominal.

Conclusions:

We have found this to be a safe and reliable technique that may be used in the laparoscopic repair of ventral, umbilical, or inguinal hernias.     

Construct Validity of Fresh Frozen Human Cadaver as a Training Model in Minimal Access Surgery

Background:

The construct validity of fresh human cadaver as a training tool has not been established previously. The aims of this study were to investigate the construct validity of fresh frozen human cadaver as a method of training in minimal access surgery and determine if novices can be rapidly trained using this model to a safe level of performance.

Methods:

Junior surgical trainees, novices (<3 laparoscopic procedure performed) in laparoscopic surgery, performed 10 repetitions of a set of structured laparoscopic tasks on fresh frozen cadavers. Expert laparoscopists (>100 laparoscopic procedures) performed 3 repetitions of identical tasks. Performances were scored using a validated, objective Global Operative Assessment of Laparoscopic Skills scale. Scores for 3 consecutive repetitions were compared between experts and novices to determine construct validity. Furthermore, to determine if the novices reached a safe level, a trimmed mean of the experts score was used to define a benchmark.Mann-Whitney U test was used for construct validity analysis and 1-sample t test to compare performances of the novice group with the benchmark safe score.

Results:

Ten novices and 2 experts were recruited. Four out of 5 tasks (nondominant to dominant hand transfer; simulated appendicectomy; intracorporeal and extracorporeal knot tying) showed construct validity. Novices’ scores became comparable to benchmark scores between the eighth and tenth repetition.

Conclusion:

Minimal access surgical training using fresh frozen human cadavers appears to have construct validity. The laparoscopic skills of novices can be accelerated through to a safe level within 8 to 10 repetitions.     

Spreader graft placement in endonasal rhinoplasty: Technique and a review of 100 cases

BACKGROUND:

Spreader grafts are widely considered to be the mainstay of treatment for insufficient internal nasal valve and are commonly placed preventively during rhinoplasty, after hump removal, to avoid middle vault collapse. Although the placement and suturing of spreader grafts in open rhinoplasty is fairly easy, their positioning and stabilization in endonasal rhinoplasty is associated with a learning curve.

METHODS:

A review of the technique with tips for the novice surgeon is presented, particularly as pertains to correct placement. The technique can be used to insert spreader grafts irrespective of whether the nasal dorsum is addressed. Suturing is usually unnecessary. A retrospective review of 100 patients in whom spreader grafts were placed was undertaken to evaluate complications such as poor placement, displacement or other complications.

RESULTS:

Although there is a learning curve to ensure the dorsal mucosal attachment is maintained while developing the pocket sufficiently dorsally for proper graft placement, the technique is easy to learn, effective, quick and technically simple to perform. Of 100 patients, three had a cartilaginous dorsal spur as the cephalic edge of the graft became visible. One patient developed an ecchymosis along the dorsum that caused a hump that resolved in two months. There were no other aesthetic or functional complications.

CONCLUSION:

The endonasal placement technique provides for simple, safe and easy placement, as well as stabilization of spreader grafts during endonasal rhinoplasty, with few complications.     

Laparoscopic Approach for Metachronous Cecal and Sigmoid Volvulus

Background:

Metachronous colonic volvulus is a rare event that has never been approached laparoscopically.

Methods:

Here we discuss the case of a 63-year-old female with a metachronous sigmoid and cecal volvulus.

Results:

The patient underwent 2 separate successful laparoscopic resections.

Discussion and Conclusion:

The following is a discussion of the case and the laparoscopic technique, accompanied by a brief review of colonic volvulus. In experienced hands, laparoscopy is a safe approach for acute colonic volvulus.     

Acute Cholecystitis is an Indication for Laparoscopic Cholecystectomy: A Prospective Study

Objective:

Acute cholecystitis has been considered as a relative or absolute contraindication to laparoscopic cholecystectomy. The purpose of this study is to present our experience of laparoscopic cholecystectomy as a safe and effective treatment of acute cholecystitis.

Methods:

Laparoscopic cholecystectomy was offered to 34 consecutive patients with acute calculous cholecystitis, diagnosed according to strict clinical and ultrasonographic criteria. We used only three trocars. The gallbladder was routinely aspirated and sharp graspers were used. We adopted the fundus-first method of dissection when safe identification of the Calot'' s triangle was difficult. The cystic duct was ligated whenever necessary.

Results:

The procedure was completed in 31 patients. The mean length of the laparoscopic procedure was 43 minutes, their mean hospital stay was 2.8 days. For the open group the mean length of the operative procedure was 66 minutes, while the mean hospital stay was 5.3 days. The overall morbidity rate was low.

Conclusions:

The benefits of laparoscopic cholecystectomy can be safely extended to patients with acute cholecystitis. The operation must be done early in the course of the disease. The surgeon should have adequate laparoscopic experience and maintain a low threshold for conversion to open exploration. Modifications in technique should be adopted to achieve a successful outcome.     

Thoracoscopic Sympathectomy for Vasospastic Diseases

Background:

Vasospastic disorders (acrocyanosis, Raynaud''s syndrome, causalgia) can arise from different etiologic factors, but the pathogenesis is always represented by an altered mechanism of vasal motility. Upper dorsal sympathectomy has been demonstrated to be an effective treatment for these disorders by decreasing peripheral resistances. Surgical technique has shown long-lasting results, and it can now be performed by endoscopic approach.

Methods:

Our experience with six cases of sympathectomy is illustrated. The indications, thoracoscopic technique, complications and longterm results are evaluated. Four women with Raynaud''s syndrome and two men with causalgia were treated in this series. After an accurate preoperative evaluation, the second, third, fourth and fifth thoracic ganglia of the sympathetic chain were identified and excised.

Results:

All patients experienced relief of symptoms with very limited pain and discomfort. They did not require further medical therapy and are relapse-free at follow-up.

Conclusions:

We conclude that thoracoscopic sympathectomy can be considered an effective, safe and simple treatment for selected cases of vasospastic phenomenon.     

Post-cardiotomy ECMO in pediatric and congenital heart surgery: impact of team training and equipment in the results

Introduction

Post-cardiotomy myocardial dysfunction requiring mechanical circulatory support occurs in about 0.5% of cases. In our environment, the use of extracorporeal membrane oxygenation has been increasing in recent years.

Objective

To evaluate the impact of investment in professional training and improvement of equipment in the rate of weaning from extracorporeal membrane oxygenation and survival.

Methods

A retrospective study. Fifty-six pediatric and/or congenital heart patients underwent post-cardiotomy extracorporeal membrane oxygenation at our institution between November 1999 and July 2014. We divided this period into two phases: phase I, 36 cases (before the structuring of the extracorporeal membrane oxygenation program) and phase II, 20 cases (after the extracorporeal membrane oxygenation program implementation) with investment in training and equipment). Were considered as primary outcomes: extracorporeal membrane oxygenation weaning and survival to hospital discharge. The results in both phases were compared using Chi-square test. To identify the impact of the different variables we used binary logistic regression analysis.

Results

Groups were comparable. In phase I, 9 patients (25%) were weaned from extracorporeal membrane oxygenation, but only 2 (5.5%) were discharged. In phase II, extracorporeal membrane oxygenation was used in 20 patients, weaning was possible in 17 (85%), with 9 (45%) hospital discharges (P<0.01). When the impact of several variables on discharge and weaning of extracorporeal membrane oxygenation was analyzed, we observe that phase II was an independent predictor of better results (P<0.001) and need for left cavities drainage was associated with worse survival (P=0.045).

Conclusion

The investment in professional training and improvement of equipment significantly increased extracorporeal membrane oxygenation results.     

Reducing patient discomfort during digital blockade: The subcutaneous single injection digital block – A simple,safe and fast procedure

BACKGROUND:

Regional anesthesia of a single finger is commonly achieved by the traditional ring block, which requires at least two painful injections in the digit. Single injection digital block techniques have been described to avoid this problem. Among these, the subcutaneous technique described by Harbison appears to be safe and to allow most procedures to be carried out with good tolerance.

OBJECTIVES:

A prospective study was designed to evaluate the results of the subcutaneous technique in terms of patient tolerance, distribution of anesthesia and efficiency.

METHODS:

All blocks were performed by a single investigator. A visual analog scale was used to evaluate pain associated with the injection. Prick testing was used to evaluate the quality of anesthesia at the volar and dorsal aspects of the phalanxes. Tolerance to the surgical procedure and the need for additional injections were also recorded.

RESULTS:

This technique allowed surgery to be performed without complementary injection most of the time and was very well tolerated. The dorsum of the proximal phalanx, however, was unpredictably included in the anesthetized territory.

CONCLUSION:

The subcutaneous single injection digital block is safe, efficient and easy to perform. It allows the treatment of all conditions on the volar aspect of the finger and on the dorsal aspect of the distal and middle phalanxes. For surgery on the dorsal aspect of the proximal phalanx, a combined single injection technique or a supplementary dorsal block should be used.     

Hybrid Technique for Removal of Eroded Adjustable Gastric Band

Background:

Intragastric migration is a late and rare postsurgical complication in patients with gastric band placement. Gastric band erosion rate has previously been described to be 1.46%. In this report, we present the case of a 43-y-old male with gastric band erosion undergoing a laparoendoscopic retrieval of the gastric band, due to intragastric migration.

Method:

A hybrid procedure was performed to retrieve the gastric band. A laparoscopic approach was initially used to extract the connecting tube. Endoscopy was then performed to cut the gastric band with a specific cutter system and was subsequently extracted transorally.

Results:

The postoperative course was uneventful. Clear liquids were started on day 1, and the patient was discharged on day 2.

Discussion:

The purpose of this study was to describe a hybrid technique for the removal of an eroded gastric band, as a safe and feasible option in patients with band erosions.

Conclusion:

The laparoscopic approach enables safe extraction of the connecting tube, while endoscopy allows extraction of the band without creating a large incision in the stomach.     

Ileosigmoid knotting—A disastrous double closed loop obstruction

INTRODUCTION

Ileosigmoid knotting (ISK) is a rare entity which needs prompt recognition and immediate surgical intervention to avoid catastrophic complications caused by gangrenous bowel and subsequent peritonitis. Preoperative investigations are only diagnostic of obstruction and CT findings are helpful but are not always available.

PRESENTATION OF CASE

This case report describes a 22 year old male presenting with acute abdomen managed with emergency exploration in view of findings of peritonitis. Intra-operatively an ileal segment was wrapped around the base of sigmoid colon with gangrenous ileal segment suggesting ISK. Resection of gangrenous ileal segment with double barrel ileostomy was done. Patient tolerated procedure well.

DISCUSSION

Patients with ileosigmoid knotting present with frank obstruction and require immediate medical and surgical treatment. This condition rapidly progresses to gangrenous bowel, generalized peritonitis and sepsis with very high mortality.

CONCLUSION

Early diagnosis, prompt fluid resuscitation, preoperative antibiotics and immediate surgical exploration are keys for optimal management of this condition.     

Current Trends in Laparoscopic Ventral Hernia Repair

Background and Objectives:

The purpose of this study was to analyze the surgical technique, postoperative complications, and possible recurrence after laparoscopic ventral hernia repair (LVHR) in comparison with open ventral hernia repair (OVHR), based on the international literature.

Database:

A Medline search of the current English literature was performed using the terms laparoscopic ventral hernia repair and incisional hernia repair.

Conclusions:

LVHR is a safe alternative to the open method, with the main advantages being minimal postoperative pain, shorter recovery, and decreased wound and mesh infections. Incidental enterotomy can be avoided by using a meticulous technique and sharp dissection to avoid thermal injury.     

Transvaginal Cholecystectomy without Abdominal Ports

Background:

Pioneers in natural orifice transvaginal cholecystectomy are in search of an approach that uses less percutaneous assistance. The approach must be safe and affordable. The authors present a successful cholecystectomy using a technique of transvaginal operative laparoscopy with no abdominal ports.

Methods:

A 24-year-old female patient with gallbladder lithiasis underwent a natural orifice cholecystectomy with only one transvaginal 12-mm port, using a laparoscope with a working channel. We used laparoscopic instruments 5 mm in diameter by 43cm in length (including a needle holder, Maryland dissector clamp, spatula, hook, suction cannula, and clip applier) and assistance with percutaneous marionette leashes.

Results:

The patient stayed in the hospital for 24 hours and was discharged without pain and without scars.

Conclusion:

Transvaginal cholecystectomy performed using an operative laparoscope with a working channel is possible in select cases. This technique requires no abdominal ports and is an alternative to culdolaparoscopy or hybrid transvaginal procedures with flexible endoscopes.     

Extracorporeal Versus Intracorporeal Anastomosis for Laparoscopic Right Hemicolectomy

Background:

During laparoscopic right hemicolectomy, the anastomosis can be created intra- or extracorporeally. This study aimed to determine whether a difference exists in short-term outcomes between these techniques.

Methods:

Prospectively collected data of 80 consecutive patients who underwent laparoscopic right hemicolectomies since 2004 were reviewed retrospectively. An intracorporeal anastomosis was performed in 23 patients, an extracorporeal anastomosis in 57.

Results:

There were no significant differences in median length of stay (4 days), number of removed lymph nodes, estimated blood loss, operative time (190 minutes intracorporeal vs. 180 minutes) and postoperative ileus (22% intracorporeal vs. 16%). The incision length was significantly shorter in the intracorporeal group (4cm vs. 5cm; P=0.004). Complications related to the anastomosis including twisting of the mesentery (n=2), anastomotic volvulus (n=1), or leak (n=1) occurred in 4 patients in the extracorporeal group compared with one minor anastomotic leak in the intracorporeal group. Major complication rates were similar between the 2 groups (4.3% intracorporeal vs. 5.3% extracorporeal).

Conclusion:

The type of anastomosis does not influence short-term outcomes after laparoscopic right hemicolectomy. An intracorporeal anastomosis results in shorter incision length and may decrease wound-related complications.     

A Simple Technique of Laparoscopic Port Closure

Background:

Laparoscopic and robotic surgery is widely practiced in modern medicine. The operative procedure is not complete until the port sites are closed with a fascial suture. We report a simple new technique that is easy, cost-effective, and quick to apply using 2 S-retractors for suture placement under direct visualization to secure the abdominal wall fascia and peritoneum.

Materials and Methods:

As a prospective consecutive case series, this technique was used for fascial closure after laparoscopy ports > 8 mm using 2 S-retractors. One S-retractor is used as a barrier protecting the contents of the abdominal cavity, reducing the risk of visceral injuries. The second S-retractor allows us to directly visualize the different layers, exposing the needle tip during its course through the fascia.

Results:

This method was used in 100 patients with no intraoperative incidents, additional operative time, or need to access costly instruments. Currently, this technique is also used by many surgeons in our institution without any difficulty. No bowel injuries or port-site hernias were reported during a mean follow-up of 6 wk postoperation and 12-mo annual follow-up.

Conclusion:

The procedure is simple, easy, cost-effective, and quick to apply.     

Percutaneous Nephrolithotomy in Autosomal Dominant Polycystic Kidney Disease: Is it Different from Percutaneous Nephrolithotomy in Normal Kidney?

Objectives

Nephrolithiasis has been reported in 20-28% of patients, of whom 50% are symptomatic for stone disease and 20% require definite urologic intervention. The management of nephrolithiasis includes oral alkali dissolution therapy, extracorporeal shock wave lithotripsy and surgical treatment. In such patients, percutaneous nephrolithotomy (PNL) as a method of stone treatment has been reported in few cases with limited experience. The aim of this study is to present our experience of PNL in autosomal dominant polycystic kidney disease (ADPKD) and assessing the outcome results.

Material and Methods

From 2002 to 2011, 22 patients (26 renal units) suffering from ADPKD with stone were managed by PNL. Demographic characteristics, operative parameters and postoperative complications were recorded and analysed.

Result

The overall success rate of PNL was 82.1% and PNL with extracorporeal shock wave lithotripsy for clinically significant residual fragments was 92.85% respectively. The hematuria required blood transfusion (n = 9), postoperative fever due to cyst infection (n = 4) and paralytic ileus (n = 3) were recorded.

Conclusion

The PNL in ADPKD PNL is safe and effective but have more postoperative complications such as bleeding requiring transfusions, fever due to cyst infection and paralytic ileus.Key Words: Percutaneous nephrolithotomy, Nephrolithiasis, Autosomal dominant polycystic kidney disease
