Latero-lateral end anastomosis for right hemicolectomy using staplers

In seven patients undergoing right hemicolectomy for benign or malignant diseases, latero-lateral end anastomoses were made using stapling devices, LS (linear stapler) and GIA (gastrointestinal anastomosis). As no complications directly related to the anastomosis occurred, we conclude that anastomosis using stapling devices for right hemicolectomy is a safe and rapid procedure.     

Sliding functional end-to-end anastomosis for colorectal surgery

Conventional functional end-to-end anastomosis (FEEA) is not indicated for left hemicolectomy, sigmoidectomy, and anterior resection. However, our original anastomosis with stapling devices (SFEEA) can be performed at any site in the intestine. We report our novel surgical technique compared with the double stapling technique (DST). Between January 2001 and August 2003, anterior resection with stapling devices was performed in 74 patients (DST, 54; SFEEA, 20). The SEEEA group was greater than the DST group in operation time and significant intraoperative blood loss. In the DST group, two postoperative complications (3.7%) occurred (leakage and stenosis). On the other hand, no complications were noted in the SFEEA group. Our novel technique for colorectal anastomosis, SFEEA, allows safe, wide, physiological, and clean anastomosis compared with FEEA.     

Right hemicolectomy for colon cancer: does the anastomotic configuration affect short-term outcomes?

Objectives

Right hemicolectomy is a common colorectal operation for resection of cancers of the right colon. The ileocolic anastomosis may be created using a stapled end-to-side, stapled side-to-side or handsewn technique. Anastomotic leak and post-operative bleeding are uncommon but serious causes of morbidity and mortality, while post-operative ileus contributes to prolonged length of stay. The aim of this study was to evaluate differences in short-term outcomes between different anastomotic configurations following right hemicolectomy for colon cancer.

Methods

We conducted a retrospective study using data from the Bowel Cancer Outcomes Registry (BCOR), including 94 hospitals across Australia and New Zealand, of all patients who underwent right hemicolectomy or extended right hemicolectomy for colon cancer with formation of a primary anastomosis between 2007 and 2021.

Results

We included 8164 patients in the analysis. There was no significant difference in rates of anastomotic leak and anastomotic bleeding based on anastomotic technique. A stapled end-to-side anastomosis was associated with a lower rate of post-operative ileus than stapled side-to-side anastomosis (6.5% vs. 7.2%; P = 0.03).

Conclusion

Both handsewn and stapled anastomosis techniques may be utilized for oncologic right hemicolectomy, with comparable rates of anastomotic leak and post-operative bleeding. Stapled end-to-side anastomosis resulted in lower rates of prolonged ileus compared to stapled side-to-side anastomoses.     

Hepatic resection using stapling devices

BACKGROUND: The progress and development of stapling devices has been remarkable. They have become indispensable for gastrointestinal diseases and are increasingly utilized in laparoscopic operations. Liver surgery applications for this technique are continuing to emerge, and in this study, we introduced the use of stapling devices to hepatic surgery. METHODS: We examined the operative procedure and efficacy of hepatic resections using stapling devices as follows: transection of Glisson's pedicle and the hepatic vein using endolineal stapling devices in right and left lobectomies; bisegmentectomy II and III en masse using a stapling device; and application of endolineal stapling devices to vessel transections and dissections of the hepatic parenchyma in laparoscopic hepatectomies. RESULTS: It was considered useful to tactfully apply stapling devices to vessel transections and dissections of the hepatic parenchyma in order to simplify the operative procedures of right or left lobectomies and lateral segmentectomies. Furthermore, the use of endoscopic stapling devices was an acceptable alternative to vessel transactions and dissections of the hepatic parenchyma in laparoscopic hepatectomies. CONCLUSIONS: We believe that stapling devices will become utilized in liver surgery hereafter.

Transoral Cervical Esophagogastrostomy Using the EEA Stapling Device

The use of automatic stapling devices in gastrointestinal surgery is becoming more common. We describe a technique using the EEA stapling device in a high cervical esophageal position to simplify a sometimes difficult anastomosis.     

The best anastomoses after colonic resection

Among the numerous anastomotic techniques after colonic resection, the mechanical sutures using staplers have been credited with a lower incidence of anastomotic leakage than hand-sewn anastomoses. This hypothesis has been tested in two multicentre, prospective, randomized trials after right hemicolectomy for carcinoma and after left colectomy with colorectal anastomosis. After right hemicolectomy, the stapled anastomosis using the GIA and TA staplers appeared to be superior to all hand-sewn anastomoses. This superiority was not apparent after left colectomy followed by colorectal anastomosis. Although the leakage rate of stapled anastomoses was similar to hand-sewn anastomoses, they carry a high rate of intra-operative mishaps. Furthermore, the stapler does not permit a lower anastomosis in this study. Finally, the overall cost of a stapled anastomosis is superior to the cost of an hand-sewn anastomosis.     

Stapling technic for esophagogastrostomy after esophagogastric resection.

A technic of esophagogastrostomy is described for constructing an end-to-side, back-to-front anastomosis using stapling devices. Twelve consecutive cases are reported with no deaths and no anastomotic leaks.     

Bowel anastomoses: The theory, the practice and the evidence base

Since the introduction of stapling instruments in the 1970s various studies have compared the results of sutured and stapled bowel anastomoses. A literature search was performed from 1960 to 2010 and articles relating to small bowel, colonic and colorectal anastomotic techniques were reviewed. ?eferences from these articles were also reviewed, and relevant articles obtained. Either a stapled or sutured gastrointestinal tract anastomosis is acceptable in most situations. The available evidence suggests that in the following situations, however, particular anastomotic techniques may result in fewer complications: A stapled side-to-side ileocolic anastomosis is preferable following a right hemicolectomy for cancer. A stapled side-to-side anastomosis is likely also preferable after an ileocolic resection for Crohn’s disease. Colorectal anastomoses can be sutured or stapled with similar results, although the incidence of strictures is higher following stapled anas-tomoses. Following reversal of loop ileostomy there is some evidence to suggest that a stapled side-to-side anastomosis or sutured enterotomy closure (rather than spout resection and sutured anastomosis) results in fewer complications. Non-randomised data has indi-cated that small bowel anastomoses are best sutured in the trauma patient. This article reviews the theory,practice and evidence base behind the various gastro-intestinal anastomoses to help the practising general surgeon make evidence based operative decisions.     

Stapling devices in gastrointestinal surgery

In a series of 189 patients, 197 operations (251 stapled anastomoses) were performed. U.S. Surgical Corporation instruments (GIA n = 156, EEA n = 36, TA n = 59) were used in surgery of the stomach, pancreas, small and large bowel, and the rates of complications were investigated. The EEA gave 14% complications because of the frequent failure (33%) of the anastomosis after low anterior resection. The reasons for failure were incomplete rings, colonic wall damage and too short rectal stumps. The use of the EEA in esophago-jejunostomy and esophago-gastrostomy was safe and the postoperative course uneventful. The GIA was used in intestinal and colonic surgery and was pleasant and quick to use (right hemicolectomy: 1 hour 40 minutes; sigmoid resection: 1 hour 45 minutes). Complications occurred in the intestine (6%) and colon (7%). Only with GIA stapled anastomoses was there a risk of hemorrhage (2.5%). The incidence of anastomotic leakage (all staplers) was 3.6%; the stapler was responsible for a 2.0% mortality. Weighing up the indications and contraindications of stapling devices, this method presents an advantageous but not indispensable method in gastrointestinal surgery.     

Manual or mechanical right colon anastomosis?

One hundred and forty patients were included in a prospective, randomized, multidepartmental study in order to compare four manual and on mechanical type of ileocolic anastomoses after right hemicolectomy for cancer. The study was designed as a pragmatic trial as defined by Schwartd. The main criterion of assessment was the anastomotic dehiscence judged with clinical criteria or a systematic follow-through with Gastrograffine on the tenth day postoperatively. All groups were similar except for a lower incidence of intraoperative septic factors for the group treated with mechanical anastomoses. The results show that the mechanical anastomosis produces fewer anastomotic dehiscences than all the other procedures except the terminolateral anastomosis with separate stitches using a slow-absorption suture material. Although it is about ten times as expensive as manual anastomosis, we suggest performing a mechanical ileocolic anastomosis after right hemicolectomy for cancer or, failing that, a manual terminolateral anastomosis with separate stitches.     

An alternative linear stapling technique for performing Roux-en-Y anastomosis

BACKGROUND: The use of stapling devices for performing gastrointestinal anastomosis has gained wide acceptance in the last decade. Linear cutting devices have been used routinely during gastrointestinal operations in our hospital since 1992. However, we still have shortage of stapling devices due to cost reduction politics. METHODS: We propose a modification of the standard technique in order to reduce the number of devices used. Our technique employs a single stapled including the section of the jejunum and the side-to-side jejunoanastomosis. RESULTS: We have used this technique for 1 year without complications related to the stapled anastomosis. CONCLUSIONS: This technique may reduce the time of reconstruction of Roux-en-Y anastomosis without interfering in its final result. This modified technique may be useful in hospitals with reduced economic resources.     

Early postoperative complications of resection anastomosis in colonic and colorectal surgery. An analysis of 624 cases]

Six hundred twenty seven patients have been studied retrospectively to evaluate early complications after sewn or staples colonic anastomosis. Seventy four per cent of the patients underwent surgery because of malignant lesions and seventy seven per cent had an elective operation. Fourty seven per cent of the patients had a sewn anastomosis, 53% a stapled anastomosis. In elective surgery, most of the right hemicolectomies and partial proctocolectomies have been performed using stapler devices (p < 0.05). In emergency surgery, most of the anastomosis after partial and total colectomy have been hand sewn (p < 0.05). Operative mortality was 5.6%. It was significantly higher in older patients (> 80 years old) (p < 0.01) and after emergency operations (p < 0.0001). The rate of anastomotic leak was 3.7% and it was significantly higher after right hemicolectomy and partial proctocolectomies when anastomosis has been hand sewn compared to stapled anastomosis (p < 0.05). With regard to postoperative mortality, intra-abdominal abscess, intestinal obstruction, evisceration, pulmonary embolism and anastomotic stenosis 1.4% (global: after a 6 months follow-up) no significant differences have been observed between sewn and stapled anastomosis.

Single‐incision laparoscopic surgery (SILS) in complex colorectal surgery: a technique offering potential and not just cosmesis

Aim Single‐incision (or port) laparoscopic surgery (SILS) has recently emerged as a method to improve morbidity and cosmetic benefit of conventional laparoscopic surgery. The literature contains two reports of SILS right hemicolectomy, and we report our experience of this technique. Method Seven consecutive, unselected patients underwent SILS retrocaecal appendicectomy, right hemicolectomy, extended right hemicolectomy, colectomy with ileorectal anastomosis, proctocolectomy, anterior resection and restorative proctocolectomy/ileoanal pouch using a single Triport (Olympus Keymed, Southend, UK), conventional instrumentation and nerve block analgesia. Three had undergone previous surgery, two had cancer and two were immunosuppressed. Results Umbilical, right‐ and left‐iliac fossa SILS was feasible using conventional instruments. Operative time ranged between 23 and 195 min (median 48 min). Four patients tolerated normal diet within 6 h (12–16 h for the remainder). Only one patient required postoperative enteral morphine (10 mg × 4). Discharge occurred between 8 and 90 h (median 16 h) of surgery. A secondary haemorrhage from the ileorectal anastomosis was managed conservatively. Conclusion SILS colorectal resection is feasible and safe when performed by an experienced laparoscopic surgeon and theatre team. It may have advantages over conventional laparoscopic surgery in terms of reduced pain, lower cost, faster recovery and cosmesis.

Minimally invasive treatment of synchronous colorectal tumours

In patients with colorectal cancers synchronous neoplastic lesions are an increasingly frequent finding at preoperative staging; 3% of the cases are other cancers while 33-35% of the synchronous lesions are villous adenomas. The treatment of most colorectal adenomas can be performed by endoscopic poplypectomy. In 5% of cases there are synchronous colorectal lesions also requiring surgical treatment. From January 1995 to June 2007 we treated 5 patients with rectal lesions by transanal endoscopic microsurgery (TEM) together with a laparoscopic colectomy for the presence of synchronous lesions at the "Clinica Chirurgica Generale e d'Urgenza" of the University of Perugia,. Surgical timing involved performing a sequential exeresis characterised by a cancer resection, followed by resection of the voluminous adenoma: TEM for rectal cancer followed by a laparoscopic right hemicolectomy with an extracorporeal anastomosis for a voluminous villous adenoma (1 patient) and laparoscopic right hemicolectomy with an extracorporeal anastomosis for cancer followed by TEM for a voluminous villous adenoma (2 patients). One patient with left colon cancer associated with a voluminous villous rectal adenoma first underwent TEM for the rectal adenoma and then a left laparoscopic hemicolectomy with an extracorporeal anastomosis in order to ease the transit of the circular mechanical stapler. Another patient with rectal and right colon adenomas first underwent TEM for a voluminous rectal sessile adenoma and later a right hemicolectomy. The use of this minimally invasive approach allowed rectum preservation and less invasive surgery.     

腹腔镜右半结肠癌切除术后消化道重建的研究现状及前景

腹腔镜右半结肠癌切除术后腹腔内吻合正逐渐成为结直肠手术领域中的热点。研究者发现:腹腔内吻合与腹腔外吻合比较,前者在促进病人术后恢复,降低术后并发症发生率等方面有潜在优势。且腹腔内吻合较腹腔外吻合病人术后胃肠功能恢复更快、术后疼痛评分更低。但对于腹腔内吻合的并发症发生率,尤其是重要指标吻合口漏的比较,尚缺乏足够证据。而手术技术不统一、吻合口漏定义不明确是目前研究的主要困难。多项高质量的前瞻性随机对照试验目前正在进行中,对于腹腔镜右半结肠癌切除术的客观评价仍需要更高级别的循证医学证据验证。笔者综合分析国内外研究进展,系统阐述腹腔镜右半结肠癌切除术后消化道重建的研究现状及前景,旨在为我国结直肠外科临床研究探索新方向。

Long-term results of invaginated ileotransversoanastomosis

The authors make an analysis of surgical treatment of 24 patients with right hemicolectomy and the formation of ileotransversoanastomosis. Depending on the method of the formation of interintestinal anastomosis the patients were divided into 2 groups: in the first group of 8 (33.3%) patients the ileotransversoanastomosis was formed by a traditional method using double row seams; in the second group of 16 (66.7%) the ileotransversoanastomosis was formed using a modified method of invagination using a single row seams. The authors based on the investigation performed make a conclusion that the results of right hemicolectomy depend on the method of forming the interintestinal anastomosis, the formation of ileotransversoanastomosis by a "classical" variant is fraught by the development of reflux enteritis. The authors propose a technique of formation of ileotransversoanastomosis by the method of invagination using a 1 row seam, performing the function of the valve, prevents regurgitation of the intestinal contents and is a measure of prophylactics of reflux-enteritis.
